It is widely established that insufficient sleep can lead to adverse health outcomes. However, for full-time workers, men still worked longer than women, working 8.2 hours compared to … Participants spent one night in the sleep laboratory where signals from polysomnography, actigraphy and WristCare were acquired. These planned activities, however, are interrupted or “augmented” by unforeseen emergencies and events (i.e., unplanned activities to which the crew must respond and resolve) such as flooding, collision, equipment casualties, etc. GAO also interviewed Department of Defense (DOD) officials and ship crews to discuss workload, manning levels, enablers of smaller crew size, and implications for the future. It is a physical, fast-paced, indoor/outdoor position in which the RSSR delivers and picks up uniforms, shop towels, chemical cleaning products and other rental items. We provide Governmentwide leadership on Federal work scheduling policies and programs. and WristCare were used for 3-6 days for nap-analysis. As total sleep time was estimated and the algorithm was optimized for this measure, the performance of the WristCare and actigraphy were similar. Conclusion Using linear regression, we examined self-report as a predictor of actigraphy-assessed sleep duration. This was an extension of the investigation by, ... On average, Sailors in the current study, excluding officers, worked 9.90 hours per week more than allotted in the Navy Standard Workweek. A sample of 56 naval cadets first filled in a general questionnaire, and then filled in a daily diary assessing sleep quality during a 30-day training mission across the Atlantic Ocean. The first goal is to assess the prevalence of musculoskeletal (MSK) symptoms, fatigue levels, and use of caffeinated beverages in a sample of active duty personnel in the U.S. Navy. Two-thirds of the sample was male. In an occupational setting, naval service personnel experience a variety of physiological and psychological stressors. Regarding the 12-month prevalence, the lower back (39.5%) and knees (33.6%) were the two body parts most frequently reported for MSK symptoms. In January 2019, the Navy codified these changes in a revision to Navy instruction (OPNAV 1000.16L), establishing a mandatory baseline to use in developing updated ship manpower requirements. In this large validation study including Hispanics/Latinos, we demonstrated a moderate correlation between self-reported and actigraphy-assessed time spent asleep. We also use the escudo rod needing it … GAO analyzed and reviewed data from fiscal years 2000 through 2015 (the most current available) on crew sizes, operating and support costs, material readiness, and the Navy's manpower requirements determination process. Extensions of the SAFTE Model to incorporate dynamic phase adjustment for both transmeridian relocation and shift work are described. Paradoxically, epidemiologic research suggests that individuals who report habitual nightly sleep greater than 9 h also are at risk for adverse health outcomes. Results show that the 3/9 is better than the 5/10 in terms of sleep quality, subjective levels of fatigue, mood, psychomotor vigilance performance, and acceptance by the Sailors. Publicly Released: Oct 21, 2020. It was found that for longitudinal vibrations, the r.m.s. A hardy disposition is regarded as an advantage in demanding and stressful environments and is associated with improved military performance. Concurrently, Hursh extended the original actigraph modeling structure and software expressions for use in other practical applications. Meal and Break Periods. In 2010, the Navy concluded that this initiative had adversely affected ship readiness and began restoring crew sizes on its ships. Eighteen 14-17-year-olds who regularly slept 5–7 hours on school nights were enrolled in a 5-week protocol during the school year.

These criteria are both condition- and time-based, and include compliance with current allowances and approved staffing standards. Interesting observations about Labor > Hours worked > Standard workweek Factoid #38 The former Yugoslavian countries have some of the highest long-term male and female unemployment rates in … Published: Nov 19, 2020. The basic concept underlying the development of a model using the Forces module is that crewmembers spend all of their time in some sort of “planned” activities/events. The findings of this study show that the 3/9 is better than the 6/6 in affording rest and sleep opportunities, sleep hygiene, fatigue levels, psychomotor vigilance performance, work demands, and acceptance from the participants. The occurrence of MSK symptoms was associated with elevated fatigue levels and excessive daytime sleepiness. Sleep duration increased during six days of a sleep extension protocol but activity levels remained similar to their baseline (normal) sleep schedule. It then provides a short tutorial on sleep architecture that describes the function and purpose of various stages of sleep. Additionally, GAO was told by shipboard personnel that in-port workload has been increasing. RSSRs are the face of Cintas to our customers and must work to build rapport with key decision makers, ensure quality standards and pro-actively solve customer concerns. In this study, we defined sociodemographic and sleep characteristics associated with misreporting and assessed whether accounting for these factors better explains variation in objective sleep duration among 2,086 participants in the Hispanic Community Health, Objective/Background Adding sociodemographic and sleep factors to self-reports increased the proportion of variance explained in actigraphy-assessed sleep slightly (18%-32%).

The study comprehensively reassessed workload and time for productive work, training, service diversion activities, sleep, personal activities, messing, and other components of a 168-hour week across the fleet. For transverse vibrations, r.m.s. Crewmembers on the 5/10 also had lower psychomotor vigilance performance than their counterparts on the 3/9 schedule (15% longer reaction times and 59% more 355-millisecond lapses greater combined with false starts). Further, studies have shown that long sleepers have decreased activity levels, which may partially explain the relationship between, Introduction accelerations are 10.8 times higher than standard when there is no attenuator, 6.4 times higher in the neoprene case and 2.7 times higher for rigid foam. The working frequencies were 0÷100 Hz. Results of multi-level analyses showed a positive main effect of hardiness on job performance. This paper describes the working fatigue model as it is being developed by the DOD laboratories, using the conceptual framework, vernacular, and notation of the SAFTE Model. activity during the school year, when short sleep is very common on school nights. The Navy Standard Workweek, paygrade tables, and workload allowances date from the 1960s and 1970s. Individual Sailors aboard USS CHUNG-HOON (DDG-93) wore Wrist Activity Monitors to collect actigraphy data. Each sailor wore an actigraph, completed a daily activity log, and performed a 3-minute psychomotor vigilance test (PVT) before and after standing watch. Congress required the Navy in the 2018 National Defense Authorization Act to work on “a comprehensive assessment” of its standard workweek and to … For each additional hour of self-reported sleep, actigraphy time spent asleep increased by 20 minutes (95% confidence interval: 19, 22). 7 years ago. The regular workweek for overtime-eligible non-bargaining unit employees is normally 35 to 40 hours per week. Phase 3 recommendations for future work are described for the upcoming fiscal year. Also in nap-analysis, actigraphy and WristCare performed similarly as the number of naps and the length of the naps were compared. These results are generally congruent with earlier research on U.S. Navy ships in which over 50% of the participants worked more than 95 hours per week, approximately 13.6 hours per day. Publicly Released: Nov 20, 2020. Both of these departments have critical duties while underway, yet they experience the most sleep deprivation. 5 : There is a change in the Here we report results of a pilot study examining the impact of experimental sleep extension on the waking sedentary, light, and moderate/vigorous activity of habitually short-sleeping teens. Study/Study of Latinos who completed more than 5 nights of wrist actigraphy and reported habitual bed/wake times from 2010 to 2013. ... Another issue of concern is the association between MSK symptoms and extended work hours, a common problem of life at sea (Green, 2009; ... Week (NSWW). In addition, because of the 24/7 nature of the military mission, opportunities for sleep often occur during circadian-misaligned time periods. We explore causal factors of insufficient sleep and inventory known effects of sleep restriction on human performance. Week 1 was a baseline to confirm habitual sleep. For example, today’s more highly … Results Includes assessments of more than 35 watchstanding plans that have been observed in civilian or military operations and/or studied in laboratories, and 331 technical references.

NA. Based on this initial work, the Army conducted a study of 1 wk of restricted sleep in 66 subjects with multiple measures of performance, termed the Sleep Dose-Response Study (SDR). The study was conducted aboard the USS Jason Dunham, a U.S. Navy destroyer operating in the vicinity of the Persian Gulf during the months of November and December 2012. Subjects were placed directly on the ship's deck, then on neoprene and rigid foam. Approximately 43% of the sample was overweight and 7% obese. ... Our results show that while underway, personnel receive much less sleep than the eight hours per day that is widely accepted as normal. For more information, contact John Pendleton at (202) 512-3489 or [email protected]. Both actigraphy and WristCare overestimated appreciably total sleep time (TST). The objective of this study is to assess the effect of ship departments on crew sleep patterns and psychomotor vigilance performance. Exempt Employees Each Sailor completed surveys detailing tasks in which they were engaged. The performance of the WristCare can be assumed to be well comparable to actigraphy in sleep/wake studies. 7-19 8-1 8-1 8-2 8-5 8-7 8-8 8-12 9-1 9-1 9-4 Appendix A Acronyms A-I Appendix B Glossary of Terms B-1 Appendix C Navy Standard Workweeks C-l More importantly, based on FAST results, most Sailors had predicted effectiveness levels lower than the predicted effectiveness level of the Navy Standard Workweek Model. More About The Navy and These Standards. The Navy expects these changes to keep factors current and accurate, thereby leading to more accurate and properly sized ship crews. his study compares the patterns of crew rest and sleep, psychomotor vigilance performance, and work demands/rest opportunities afforded by two different schedules, the 3-hour on/9-hour off (“3/9”) and the 6-hour on/6-hour off (“6/6”) watchstanding schedules. Publicly Released: Nov 19, 2020. This book is an annotated bibliography with more than 680 references. We postulate that concerns about the implementation of the 3/9 schedule may be ameliorated by adjusting sunlight exposure, providing sleep hygiene training, and by considering an alternative distribution of duties between watch sections to allow protected sleep times for those on night watch duty. Sleep ≥56 hours/7-day period USN does not have a regulation dedicated to work/rest times (except aviation) Results • Participants –Predominantly young (25.0±3.72 years of age) –Male (80%) –Enlisted (95%) • Crewmembers worked ≥14 hours/day for 21% of Crewmembers from the Reactor Department on the USS NIMITZ (N=117, 24.6±3.89 years old, 95 males, 109 enlisted, with 4.25±2.65 years of active duty) participated in this study. During the weigh-in portion of their semiannual Physical Readiness Test in Spring 2014, crewmembers of a U.S. Navy aircraft carrier were invited to complete an anonymous survey. Actigraphy results show that crewmembers were chronically sleep deprived, receiving on average 6.6 hours of daily sleep. Naval cohorts rely heavily on personnel to ensure the efficient running of naval organisations. School night sleep averaged 6.16 hours during HAB and 7.34 hours during EXT (p<.001). An Overview of Sleep Th is fi rst section of the chapter provides the rationale and scientifi c justifi cation for the entirety of the program of research that follows. The revised instruction further includes criteria and triggers that necessitate the updating of manpower requirements. Additionally, the January 2019 revision of OPNAVINST 1000.16L codified the process by which these standards should be revised. For example, it recommended a readjustment of the productive work factor, the creation of a new individual training component, and an increased allotment for service diversion activities in the workweek.

For the purposes of calculating payroll, the University’s standard workweek begins on Sunday morning at 12:01 a.m. and ends the following Saturday at 12:00 midnight. The final report recommended changes to the afloat workweek. Th is introductory sleep overview concludes with a summary of the eff ects of restricted sleep on various kinds of human performance. The paper concludes with a discussion of several important modeling issues that remain to be addressed. Sailor shows the greatest deviation from the Navy Standard Workweek (NSW) in the categories of standing watch and training. Support (If Any) . In response, the Navy released guidance for updating these factors in a March 2018 memorandum. Even though the 3/9 schedule, as a whole, is better than the 5/10, analysis showed that two 3/9 watch sections, those standing the night watches, were accepted less by the Sailors. the basic 40-hour workweek is scheduled on 5 days, Monday through Friday when possible, and the 2 days outside the basic workweek are consecutive; (C) the working hours in each day in the basic workweek are the same; (D) the basic nonovertime workday may not exceed 8 hours; (E) The eight-hour workday, or the 40-hour workweek, didn't become the modern labor standard by accident. Until the Navy makes needed changes to its factors and instruction used in determining manpower requirements, its ships may not have the right number and skill mix of sailors to maintain readiness and prevent overworking its sailors. Publicly Released: May 18, 2017. Most naval services arrange annual physical fitness and body composition tests to ensure the physical readiness of personnel. The current findings suggest that extending time in bed alone does not alter waking activity counts in young healthy adults. The link between extended sleep and adverse health outcomes may be attributable to other phenotypic factors, or other biological correlates of extended sleep and poor health. The references cited herein address the design of shiftwork schedules and the effects of shiftwork on safety, health and human performance in many work environments. 3 result, they may be incompatible with today’s technology, personnel policies, workforce, and business practices. No limits were placed upon dates of publication; however, the bibliography generally reaches back slightly more than 30 years through about 2010. Covered nonexempt workers are entitled to a minimum wage of not less than $7.25 per hour effective July 24, 2009. | The first step is to reset the “applicable productive workweek” portion of the standard Navy workweek (SNWW) to 67 hours. What does this mean for a larger fleet in the future? In our sample, results demonstrate that the two departments most affected are the Operations and the Engineering. Publicly Released: Nov 5, 2020. Recommendation: To ensure that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet, the Under Secretary of Defense for Personnel and Readiness should direct the Secretary of the Navy to have the Navy conduct a comprehensive reassessment of the Navy standard workweek and make any necessary adjustments.

Total ship operating and support costs—which include personnel and maintenance costs—and maintenance backlogs increased during the optimal manning period (2003–2012) and have continued to increase for most ship classes since the initiative ended. As a. The Navy has used these and other updated factors, to recalculate the manpower requirements for the DDG 51 destroyer class, leading to a required crew size increase of about 10 percent (an additional 32 crew members) and for the LPD 17 amphibious transport dock class, leading to a required crew size increases of about 6 percent, or 23 additional crew members. In January 2019, the Navy revised its guidance (OPNAVINST 1000.16L) to require that in-port workload be a primary factor in developing manpower requirements for all surface ships. Moving forward, the Navy will likely face manning challenges as it seeks to increase the size of its fleet. The Navy also calculated manpower costs associated with the planned larger fleet size, and these projected costs also rise in proportion to the increasing numbers of sailors needed to man the larger fleet. In November 2018, the Navy completed its Operational Afloat Workload Study Final Report, conducted by the Navy Manpower Analysis Center. DOD concurred with each recommendation. The demands placed upon the United States Navy are greater now than ever before. Second, to develop the appropriate manning models in IMPRINT. Mean amount of time spent asleep was 7.85 (standard deviation, 1.12) hours by self-report and 6.74 (standard deviation, 1.02) hours by actigraphy; correlation between them was 0.43. ... Of note, the typical workday of active duty service members generally includes many other activities in addition to standing watch. The participants were studied in three study groups: all subjects, senior subjects (age > 65 years) and middle-aged subjects (age < 65 years). Same here in shore duty an every other week is four day week. Access scientific knowledge from anywhere. Over a 3-day rotation cycle, a crewmember on the 5/10 watchstanding schedule sleeps at three distinctly different times on each subsequent day, experiences two periods of sustained wakefulness, and has one night with only a 4-hour opportunity for sleep. Status of Efforts to Schedule and Hold Timely Entrance Conferences, Joint Cyber Warfighting Architecture Would Benefit from Defined Goals and Governance, Comprehensive Plan Needed to Improve Stakeholder Engagement in the Development of New Military Intelligence System. Discussion In this project, we used the IMPRINT Pro Forces Module to build models of the crew of the Littoral Combat Ship (LCS). If a Navy ship doesn’t have the right number and mix of sailors, it may end up overworking its crew—which can have detrimental effects on safety, morale, and retention. The current standard five-day week got 28% support. Short sleep has been associated with obesity and we previously found that shortening sleep during summer months causes teens to eat more calories. It is notable, however, that the typical workday of active duty service members includes much more than watchstanding. This study provided numerical estimation of parameters for the Walter Reed Army Institute of Research Sleep Performance Model (SPM) and elucidated the relationships among several sleep-related performance measures. It begins with a discussion of circadian rhythms and the requirement for sleep in humans. In addition, actigraphy. The fleet is projected to grow from its current 274 ships to as many as 355 ships, but the Navy has not determined how many personnel will need to be added to man those ships. The sailors' available time includes watch standing, maintenance, training, and meetings. And 20% said they would prefer a three-day workweek. There were differences between crewmembers on the two schedules in the expression of negative opinions about the adequacy of their sleep (3/9: 30%; 5/10: 80%) with over twice as many negative opinions for the 5/10 group. This result agrees with earlier research findings conducted on Navy ships (Green, 2009; ... As previously described, some of these limitations are associated with the assumptions of the model about the activities/duties of the crewmembers (United States Government Accountability Office, 2010). Survey data were compared to the Navy Standard Workweek. Since the implementation of optimal manning, the Navy reduced crew sizes, which decreased the associated personnel costs for most ship classes, even as crews were partially restored. Download First, to develop the design concept of a model describing the manpower requirements of LCS-1 Freedom. The unexpected persistence of performance effects following chronic sleep restriction found in the SDR study necessitated some revisions of the SAFTE Model that are also described. The agreement percents between the scorings of polysomnography and actigraphy, and between polysomnography and WristCare were about 80 % for all study groups. The Navy has completed in-port workload studies for two ship classes which led to increases in their crew size requirements, and is now mandated to consider in-port workload of other ship classes as it updates their manpower requirements. In addition, as the Navy has gained experience operating its new ship classes, their crew sizes have grown and may continue to do so. This phase included two tasks. On the 3/9, significantly fewer Sailors reported not having enough time to sleep, as contrasted with the 5/10 (3/9: 52%; 5/10: 88%; p<0.001). Similarly, two other post graduate studies on different vessels in the U.S. Navy found that participants worked more hours per week on average than allowed by the NSWW and that they suffered from inadequate sleep. They apply maritime powers in their offensive operations when countering enemies and in their defensive operations to protect the U.S. territory and trade. Many countries regulate the work week by law, such as stipulating minimum daily rest periods, annual holidays, and a maximum number of working hours per week. How many days and hours do you work a week in the Navy? However, there is concern that extending sleep may cut into physical activity time. Current and analytically based manpower requirements are essential to ensuring that crews can maintain readiness and prevent overwork that can affect safety, morale, and retention. The Navy only has one location for enlisted basic training: the Great Lakes Naval Training Center in Illinois. (September 2019) ( PDF ) The Department of Labor’s (DOL) Wage and Hour Division (WHD) is responsible for administering and enforcing some of our nation's most comprehensive labor laws, including the minimum wage, overtime, recordkeeping, and youth employment provisions of the Fair Labor Standards Act (FLSA) .. Crewmembers on the 5/10 also had lower psychomotor vigilance performance than their counterparts on the 3/9 schedule (15% longer reaction times and 59% more 355-millisecond lapses greater combined with false starts). b. Overall, 61% of participants exceeded the Available Time allotted in … There were no significant or clinically-relevant differences in 24-h activity or activity during the active or sleep period between baseline and sleep extension conditions. Phase 1 of this effort was focused on model development for naval applications—specifically, to validate the use of IMPRINT Pro Forces model simulations for the LCS manpower requirements (Hollins & Leszczynski, 2014). Furthermore, when changing standards, such as increasing the standard workweek from 67 to 70 hours, the Navy did not conduct the types of analysis called for in its guidance to verify that these changes were warranted. Correlations between self-reported and actigraphy-assessed time spent asleep were lower with male sex, younger age, sleep efficiency <85%, and night-to-night variability in sleep duration ≥1.5 hours. Crewmembers (N=93) from an Arleigh Burke-type destroyer participated in a 16-day quasi-experimental study while the ship was forward deployed. That will improve the working and resting conditions of seafaring personnel on a pusher boat that travels over long distances. Specifically, crewmembers on the 3/9 received more sleep during nighttime hours, whereas crewmembers on the 6/6 had to sleep during the day to compensate for their lack of sleep during nighttime hours. We conclude with an argument for a more deliberate protection and promotion of sleep. The water flow rate was 0.76 m/s and there were good visibility conditions and light wind. The accelerations transmitted to man were measured with Seat PAD 01dB triaxial accelerometers mounted on the floor of the ship and connected to the NetdB-Complex system for analysis and measurement. The Navy's process to determine manpower requirements—the number and skill mix of sailors needed for its ships—does not fully account for all ship workload. This study evaluates the ability of the device to discriminate sleep/wake patterns during nighttime and during napping. © 2008-2020 ResearchGate GmbH. Survey data were compared to the Navy Standard Workweek. The Navy is called upon when there is a threat at sea or coming from the sea. In addition to this, it will also evaluate the methods that are used to assess both physiological and psychological wellbeing. In their off-watch period, crewmembers must fit in other ship duties as well as personal activities such as eating, hygiene, and sleep. Agency Affected: Department of Defense: Office of the Under Secretary for Personnel and Readiness. Of the 122 participants in the overall study, 52 were shift workers using either the 3/9 (n=41) or the 6/6 (n=11) schedules. In addition, female participants reported significantly higher mood scale scores than the male participants, and topside participants were getting significantly less sleep than belowdecks participants. These 52 individuals are the focus of the current analysis. We had 767 respondents; approximately, a 30% response rate. NA. Although not statistically significant due to its large variability, the pattern of PVT results agrees with the sleep analysis. On days worked, employed men worked an average of 34 minutes more than employed women - this difference may be on account of women’s higher instance of part-time work (there were almost twice as many part-time female employees as there were part-time male employees). This pilot study indicates that, when short-sleeping teens sleep longer, they engage in less sedentary activity without seeming detriment in their moderate/vigorous activity. The Navy used its Manpower Projection Tool to project its future manpower needs associated with the current 355-ship requirement and 30-year shipbuilding plan. Compared to crewmembers without MSK symptoms, crewmembers with MSK symptoms are more likely to report elevated daytime sleepiness (g=0.26 – 0.39), increased levels of fatigue (g=0.54 – 0.59) and are more likely to use sleep-promoting medications. The Folly of Optimal Manning. Comments: DOD concurred with our recommendation, citing its commitment to ensuring that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet. Hours by Gender. We then describe the particular challenges of fatigue and sleep deprivation in military operational environments. Approximately 58% of the respondents reported at least one MSK symptom in the last 12 months, 44% reported at least one symptom in the last seven days, and 20.4% reported that MSK symptoms prevented them from carrying out their normal activities. This research seeks to determine if the Navy Standard Workweek accurately reflects the activities of deployed Sailors and determine their work and rest patterns. All new recruits will spend boot camp here, but don't worry about doing drills in inclement weather; unlike the other branches of the U.S. military, most of Navy … accelerations are 9 times higher than standard if there is no attenuator, 4.8 times higher than standard for neoprene and 2.4 times higher in the case of rigid foam. It was also found that shifting the watch forward is better than shifting the watch back, but not shifting the watch results in the best performance characteristics. Publicly Released: Nov 18, 2020. Navy officials attributed maintenance cost increases to reduced crews, longer deployments, and other factors. Browse all our products here, Explore our Key Issues on National Defense. Previous research indicates sedentary behavior is associated with obesity risk in teens. The aim of the present study is to investigate the moderating role of hardiness in the sleep quality-job performance relationship in a sample of naval cadets during a demanding training exercise. Further, other research suggests that risk for other negative consequences resulting from short sleep (i.e., higher caloric intake) may be attenuated. Although sleep deprivation was evident in both watch schedules, results show that crewmembers on the 3/9 received more sleep than their peers on the 6/6, with 6.46 ± 0.77 hours versus 5.89 ± 0.87 hours, respectively. Recent evidence suggests that hardiness may also be related to resilience with respect to sleep disturbances. Call MyNavy Career Center: 833-330-MNCC, or 901-874-MNCC (DSN 882-6622), Email MNCC, MNCC Chat Comments or Suggestions about this Website? The purpose of this paper is to find a damping material for the vibrations generated by the equipment of a ship. We develop and maintain Governmentwide regulations and policies on the administration of work schedules, including the basic 40-hour workweek, holidays, and flexible and compressed work schedules.However, each Federal agency is responsible for administering work scheduling policies and programs for its … The model predicts that, at current manning levels, certain critical rates (particularly engineers and combat systems sailors) consistently get the least amount of sleep, accomplish the most amount of work, and respond to more unplanned events. Compared to HAB, during EXT teens averaged a 55 minute reduction in daily waking sedentary activity (p=.001) with a slight increase in light activity (7 minutes; p=.048) but no difference in moderate/vigorous activity (p=.53). On average, the Sailors worked 16.95 hours per week more than they were allotted in the Navy Standard Workweek which equated to 2.4 hours … All rights reserved. Symptoms in these two body parts were also the most frequently reported as preventing participants from normal activities. "In another NPS masters thesis, Kim Green expanded upon the Navy Standard Workweek (NSWW) studies of. In contrast, there was a main effect of condition when examining sleep duration by day between conditions (Day: F(5,21) = 1.60, p = 0.16; Condition: F(1,25) = 167.31, p < 0.001; Day by Condition: F(5,21) = 2.31, p = 0.07), such that sleep duration was longer during the sleep extension condition. Each Sailor completed surveys detailing tasks in which they were engaged. Teens wore wrist actigraphy to assess sleep fidelity and waist-mounted accelerometers to determine amounts of sedentary, light, moderate/vigorous activity during each condition. Nearly half of adolescents sleep less than 7 hours on school nights. Using actigraphic recordings, approximately 22% of the participants occasionally napped during their night watch. long sleep duration and mortality. ... Concurrently, a master's student at the U.S. Navy Postgraduate School was also addressing the work hours issue. Future efforts should strive to further quantify this phenomenon and to address methods to ameliorate the problem. In contrast, Sailors on the 3/9 have a fixed sleep schedule every day and they experience, at most, 16- to 17-hour periods of sustained wakefulness. Comments: DOD concurred with our recommendation, citing its commitment to ensuring that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet. Rest and sleep opportunities were varied significantly depending on the department to which the crewmember belongs. This research seeks to determine if the Navy Standard Workweek accurately reflects the activities of deployed Sailors and determine their work and rest patterns. The experiments were made upstream the Danube. Phase 1 successfully showed that IMPRINT Pro Forces could be used to estimate manning levels with regard to the distribution of crew rates and required qualifications (Navy Enlisted Classifications [NECs]) for the LCS 1 mission requirements through simulations of planned and unplanned events, based on actual data collected from the LCS crew. The average value of the PVT scores was better on the 3/9 compared to the 6/6, but not at statistically significant levels. In terms of work demands, crewmembers on the 6/6 schedule have considerably long workdays, with, on average, 15 hours on duty, which corresponds to approximately 30% more time on duty than allocated in the Navy Standard Work Week (NSWW) criterion (on average, 105 hours compared to 81 hours weekly). Military sleeping conditions are less than ideal, further exacerbating a chronic sleep debt. In addition to the physical capabilities, personnel are impacted by fatigue, nutrition and psychological stressors such as copping in stressful situations or dealing with time away from family and friends. Second, the study seeks to explore the associations among musculoskeletal symptoms, reported sleep, daytime alertness, and fatigue levels. References listed here, along with keywords suggested by these publications, should allow the reader to search an area of interest almost completely. However, increased maintenance costs offset the reductions in personnel costs, as shown below. Recommendation: To ensure that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet, the Under Secretary of Defense for Personnel and Readiness should direct the Secretary of the Navy to have the Navy develop criteria and update guidance for reassessing the factors used to calculate manpower requirements periodically or when conditions change. Comments: DOD concurred with our recommendation, citing its commitment to ensuring that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet. The study suggests that the device may be used in long-term monitoring of sleep/wake patterns with similar performance to actigraphy. As a result, crewmembers work long hours and suffer from sleep deprivation, sleep fragmentation, suboptimal performance, and worrisome levels of alertness (Green, 2009; ... On average, working hours were exceeded by over 20 h per week, which also indicates that participants got nearly nine less hours sleep per week than is recommended in the NSWW [284]. Older crewmembers were more likely to report MSK symptoms, and females reported more MSK symptoms than males. The primary manning tool used by the United States Navy to determine manpower requirements is the Navy Standard Workweek. Participants were 32 adults aged 26-89 years. Maritime Watchstanding Plans: Origins, Variants and Effectiveness, Work and Rest Patterns and Psychomotor Vigilance Performance of Crewmembers of the USS Jason Dunham: A Comparison of the 3/9 and 6/6 Watchstanding Schedules, Optimization of shipboard manning levels using IMPRINT Pro Forces Module, Identifying Capabilities Gaps in Shipboard Visit, Board, Search, Seizure (VBSS) Teams, It's been a hard day's night: A diary study on hardiness and reduced sleep quality among naval sailors, Comparative study of vibration-absorbing materials to improve the comfort of the crew on a river ship, The Role of Sleep in Human Performance and Well-Being, Sleep and Fatigue Issues in Military Operations, A comparison between the 5hrs-on/10hrs-off and 3hrs-on/9hrs-off watch standing schedules, A review of the physiological and psychological health and wellbeing of naval service personnel and the modalities used for monitoring, Analysis of Alternative Watch Schedules for Shipboard Operations: A Guide for Commanders, Prevalence of Musculoskeletal Symptoms, Excessive Daytime Sleepiness, and Fatigue in the crewmembers of a U.S. Navy Ship, The Effect of Ship Department on Crew Sleep Patterns and Psychomotor Vigilance Performance, Fatigue Models for Applied Research in Warfighting. How does the Navy determines its crew needs? Recommendation: To ensure that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet, the Under Secretary of Defense for Personnel and Readiness should direct the Secretary of the Navy to have the Navy update guidance to require examination of in-port workload and identify the manpower necessary to execute in-port workload for all surface ship classes. If the new work schedule code is P, Q, S, or T, enter in block 33 the total hours employee will work per bi-weekly pay period. This report examines (1) any trends in ship operating and support costs and maintenance backlogs, (2) the extent to which the Navy's manpower requirements process accounts for ship workload, and (3) any manning challenges and implications for the future. The convoy was made up of a self-propelled vessel and four barges. Comments: DOD concurred with our recommendation, citing its commitment to ensuring that the Navy's manpower requirements are current and analytically based and will meet the needs of the existing and future surface fleet. Overall, these results may be explained by considering the timing of sleep and the periods of sustained wakefulness experienced on the 5/10. NAVY PERSONNEL COMMAND: 5720 Integrity Drive, Millington TN 38055-0000 Address Correspondence to: Attn: PERS-### or BUPERS-### This is an official U.S. Navy Website Need Career, Pay or Personnel help? Performance and health have been shown to be profoundly affected by lack of sleep; we ignore the need for sleep at our peril. The two schedules differed significantly in the variability of psychomotor vigilance performance; specifically, crewmembers on the 6/6 schedule had larger variability than those on the 3/9 in 11 of the 13 Psychomotor Vigilance Task (PVT) metrics analyzed (p<0.05). "It's important," Schawbel says, "because it shows people want to work." We hypothesize that (1) Hardiness positively influences daily job performance, (2) daily sleep quality positively influences daily job performance, and (3) Hardiness buffers the impact of poor daily sleep quality on daily job performance. Join ResearchGate to find the people and research you need to help your work. It was shown the importance of a vibration attenuator for the health, comfort and implicitly for labour productivity of river sailing personnel. Naval Sea Systems Command had set the rate at a maximum of about 18% more hours than the standard 40-hour workweek, but actual overtime jumped up to nearly 45% in some cases. Sleep/wake patterns were extracted from polysomnography, actigraphy and WristCare for the night slept in sleep laboratory. Crewmembers reporting MSK symptoms were more likely to consume caffeinated beverages. Objective Changes in Activity Levels Following Sleep Extension as Measured by Wrist Actigraphy. This study looked at one set of crewmembers, based on the current Preliminary Ship Manning Document (PSMD) with regard to crew rates, as well as required qualifications (or NECs), to determine the effects of normal underway operations—as well as unplanned events—on the fatigue levels of a typical LCS crew. Although crewmembers on both the 5/10 and the 3/9 received, on average, approximately seven hours of sleep per day, the sleep hygiene and acceptance of the two schedules differ considerably. The results are similar in the case of transmissibility determination. As ships become more versatile, Sailors must become proficient in many warfare areas while maintaining operational readiness. Daytime sleepiness and mood states deteriorated during the underway when using the 5/10, whereas daytime sleepiness and mood states of Sailors on the 3/9 did not change. The model became known as the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) Model, and Hursh has applied it in the construction of a Fatigue Avoidance Scheduling Tool. The influence of sleep extension (longer time in bed) on levels of daily activity has not yet been established. Military operations span a wide spectrum ranging from basic military training and education, through military operations other than war (MOOTW), to war itself. ", Most studies of sleep and health outcomes rely on self-reported sleep duration, although correlation with objective measures is poor. Cadets high (vs. low) on dispositional hardiness were less affected by poor sleep quality, also after controlling for neuroticism. Components such as aerobic and strength capabilities are assessed, however, other components of physical fitness such as speed, agility, anaerobic capacity and flexibility are not. Standard Form 50. Actigraphy data were analyzed using the Fatigue Avoidance Scheduling Tool (FAST), which uses the Sleep, Activity, Fatigue and Task Effectiveness (SAFTE) Model, to predict the waking effectiveness level of each Sailor. The primary purpose of the book was to gather relevant literature from databases with comprehensive coverage. Sleep is unquestionably a critical commodity for humans, yet research indicates a growing sleep debt prevalent in many segments of society. This thesis found that RENTZ participants, excluding officers, on average, worked 20.24 hours per week in excess of the hours set forth in the NSWW model, while sleeping 8.98 fewer hours per week than mandated by the NSWW. I know the typical civilian full time job is 40 hours/4-5 days a week, but what is it in the Navy if any different? By their very nature, military operations are conducted under tremendously stressful conditions. The U.S. Department of Defense (DOD) has long pursued applied research concerning fatigue in sustained and continuous military operations. A total of 26 healthy volunteers wore wrist accelerometer devices (Actiwatch 2.0, Philips) in order to objectively measure sleep and activity for six days during their normal schedules and for six days during a sleep extension (10 h time in bed) intervention. Specifically, the Operations department, followed by Engineering, had the worst sleep patterns as indicated by reduced and fragmented sleep. Maintenance backlogs also increased during the optimal manning period and have continued to grow. "Both officer and enlisted workload, by definition are based upon a standard of individual work referred to as the Navy standard workweek. Correlational findings are mixed on the relationship between sleep and physical, Vivago WristCare is a new activity monitoring device, which allows long-term online monitoring of the activity of the user. Without updating its manpower factors and requirements and identifying the personnel cost implications of fleet size increases, the Navy cannot articulate its resource needs to decision makers. In the U.S. Navy, the navy standard workweek model (NSWW) outlines the number of hours a sailor will work/rest on-board ships. The Improved Performance Research Integration Tool (IMPRINT) is a dynamic, stochastic, discrete-event modeling tool used to develop a model of the system of interest. Although the Navy has updated some of its manpower factors, its instruction does not require reassessing factors to ensure they remain valid or require measuring workload while ships are in port. In November 2018, the Navy completed its Operational Afloat Workload Study Final Report, conducted by the Navy Manpower Analysis Center. Published: Nov 20, 2020. The projection shows the need for annual increases of enlisted personnel through 2024, and sustained growth in end strength peaking in fiscal year 2033 as the number of ships in the fleet increases. This is the second phase of a longitudinal study comparing the fatigue levels, workload, and performance of crewmembers working on the 3-hrs on/9-hrs off (3/9) and the 5-hrs on/10-hrs off (5/10) watchstanding schedules. Daily job performance was assessed by using peer-ratings. In 2001, the Navy began reducing crew sizes on surface ships through an initiative called optimal manning, which was intended to achieve workload efficiencies and reduce personnel costs. Almost any sailor will tell you that they do not have enough time in the day to accomplish all of their required tasks, ... Coping with shift work represents a good model for testing the role of hardiness in relation to naval sleep disturbances. Navy Standard Work Week (NSWW) –obs. For vertical vibrations, accelerations r.m.s is 5.9 times higher than standard if there is no attenuator, 3.4 times higher for neoprene and 1.7 times higher for rigid foam. Participants reported receiving approximately six hours of sleep per day while at sea; more than 50% of them rated their sleep as less than needed and 31.8% reported increased daytime sleepiness (ESS scores > 10). This epidemiological, cross-sectional, questionnaire-based study has two goals. Results Methods Subscribe. As such, the wellbeing of personnel is essential. Published: Nov 5, 2020. It is widely established that insufficient sleep can lead to adverse health outcomes. However, for full-time workers, men still worked longer than women, working 8.2 hours compared to … Participants spent one night in the sleep laboratory where signals from polysomnography, actigraphy and WristCare were acquired. These planned activities, however, are interrupted or “augmented” by unforeseen emergencies and events (i.e., unplanned activities to which the crew must respond and resolve) such as flooding, collision, equipment casualties, etc. GAO also interviewed Department of Defense (DOD) officials and ship crews to discuss workload, manning levels, enablers of smaller crew size, and implications for the future. It is a physical, fast-paced, indoor/outdoor position in which the RSSR delivers and picks up uniforms, shop towels, chemical cleaning products and other rental items. We provide Governmentwide leadership on Federal work scheduling policies and programs. and WristCare were used for 3-6 days for nap-analysis. As total sleep time was estimated and the algorithm was optimized for this measure, the performance of the WristCare and actigraphy were similar. Conclusion Using linear regression, we examined self-report as a predictor of actigraphy-assessed sleep duration. This was an extension of the investigation by, ... On average, Sailors in the current study, excluding officers, worked 9.90 hours per week more than allotted in the Navy Standard Workweek. A sample of 56 naval cadets first filled in a general questionnaire, and then filled in a daily diary assessing sleep quality during a 30-day training mission across the Atlantic Ocean. The first goal is to assess the prevalence of musculoskeletal (MSK) symptoms, fatigue levels, and use of caffeinated beverages in a sample of active duty personnel in the U.S. Navy. Two-thirds of the sample was male. In an occupational setting, naval service personnel experience a variety of physiological and psychological stressors. Regarding the 12-month prevalence, the lower back (39.5%) and knees (33.6%) were the two body parts most frequently reported for MSK symptoms. In January 2019, the Navy codified these changes in a revision to Navy instruction (OPNAV 1000.16L), establishing a mandatory baseline to use in developing updated ship manpower requirements. In this large validation study including Hispanics/Latinos, we demonstrated a moderate correlation between self-reported and actigraphy-assessed time spent asleep. We also use the escudo rod needing it … GAO analyzed and reviewed data from fiscal years 2000 through 2015 (the most current available) on crew sizes, operating and support costs, material readiness, and the Navy's manpower requirements determination process. Extensions of the SAFTE Model to incorporate dynamic phase adjustment for both transmeridian relocation and shift work are described. Paradoxically, epidemiologic research suggests that individuals who report habitual nightly sleep greater than 9 h also are at risk for adverse health outcomes. Results show that the 3/9 is better than the 5/10 in terms of sleep quality, subjective levels of fatigue, mood, psychomotor vigilance performance, and acceptance by the Sailors. Publicly Released: Oct 21, 2020. It was found that for longitudinal vibrations, the r.m.s. A hardy disposition is regarded as an advantage in demanding and stressful environments and is associated with improved military performance. Concurrently, Hursh extended the original actigraph modeling structure and software expressions for use in other practical applications. Meal and Break Periods. In 2010, the Navy concluded that this initiative had adversely affected ship readiness and began restoring crew sizes on its ships. Eighteen 14-17-year-olds who regularly slept 5–7 hours on school nights were enrolled in a 5-week protocol during the school year. Looking for more? 21 comments 83% Upvoted This chapter explores the influence of sleep on human performance and well-being. These criteria are both condition- and time-based, and include compliance with current allowances and approved staffing standards. Interesting observations about Labor > Hours worked > Standard workweek Factoid #38 The former Yugoslavian countries have some of the highest long-term male and female unemployment rates in … Published: Nov 19, 2020. The basic concept underlying the development of a model using the Forces module is that crewmembers spend all of their time in some sort of “planned” activities/events. The findings of this study show that the 3/9 is better than the 6/6 in affording rest and sleep opportunities, sleep hygiene, fatigue levels, psychomotor vigilance performance, work demands, and acceptance from the participants. The occurrence of MSK symptoms was associated with elevated fatigue levels and excessive daytime sleepiness. Sleep duration increased during six days of a sleep extension protocol but activity levels remained similar to their baseline (normal) sleep schedule. It then provides a short tutorial on sleep architecture that describes the function and purpose of various stages of sleep. Additionally, GAO was told by shipboard personnel that in-port workload has been increasing. RSSRs are the face of Cintas to our customers and must work to build rapport with key decision makers, ensure quality standards and pro-actively solve customer concerns. In this study, we defined sociodemographic and sleep characteristics associated with misreporting and assessed whether accounting for these factors better explains variation in objective sleep duration among 2,086 participants in the Hispanic Community Health, Objective/Background Adding sociodemographic and sleep factors to self-reports increased the proportion of variance explained in actigraphy-assessed sleep slightly (18%-32%). Published: Oct 29, 2020. Enter new service computation date in block 31, the new work schedule code in block 32, and Remark B31 in Part F of the Standard Form 52 or block 45 of the Standard Form 50. The study comprehensively reassessed workload and time for productive work, training, service diversion activities, sleep, personal activities, messing, and other components of a 168-hour week across the fleet. For transverse vibrations, r.m.s. Crewmembers on the 5/10 also had lower psychomotor vigilance performance than their counterparts on the 3/9 schedule (15% longer reaction times and 59% more 355-millisecond lapses greater combined with false starts). Further, studies have shown that long sleepers have decreased activity levels, which may partially explain the relationship between, Introduction accelerations are 10.8 times higher than standard when there is no attenuator, 6.4 times higher in the neoprene case and 2.7 times higher for rigid foam. The working frequencies were 0÷100 Hz. Results of multi-level analyses showed a positive main effect of hardiness on job performance. This paper describes the working fatigue model as it is being developed by the DOD laboratories, using the conceptual framework, vernacular, and notation of the SAFTE Model. activity during the school year, when short sleep is very common on school nights. The Navy Standard Workweek, paygrade tables, and workload allowances date from the 1960s and 1970s. Individual Sailors aboard USS CHUNG-HOON (DDG-93) wore Wrist Activity Monitors to collect actigraphy data. Each sailor wore an actigraph, completed a daily activity log, and performed a 3-minute psychomotor vigilance test (PVT) before and after standing watch. Congress required the Navy in the 2018 National Defense Authorization Act to work on “a comprehensive assessment” of its standard workweek and to … For each additional hour of self-reported sleep, actigraphy time spent asleep increased by 20 minutes (95% confidence interval: 19, 22). 7 years ago. The regular workweek for overtime-eligible non-bargaining unit employees is normally 35 to 40 hours per week. Phase 3 recommendations for future work are described for the upcoming fiscal year. Also in nap-analysis, actigraphy and WristCare performed similarly as the number of naps and the length of the naps were compared. These results are generally congruent with earlier research on U.S. Navy ships in which over 50% of the participants worked more than 95 hours per week, approximately 13.6 hours per day. Publicly Released: Nov 20, 2020. Both of these departments have critical duties while underway, yet they experience the most sleep deprivation. 5 : There is a change in the Here we report results of a pilot study examining the impact of experimental sleep extension on the waking sedentary, light, and moderate/vigorous activity of habitually short-sleeping teens. Study/Study of Latinos who completed more than 5 nights of wrist actigraphy and reported habitual bed/wake times from 2010 to 2013. ... Another issue of concern is the association between MSK symptoms and extended work hours, a common problem of life at sea (Green, 2009; ... Week (NSWW). In addition, because of the 24/7 nature of the military mission, opportunities for sleep often occur during circadian-misaligned time periods. We explore causal factors of insufficient sleep and inventory known effects of sleep restriction on human performance. Week 1 was a baseline to confirm habitual sleep. For example, today’s more highly … Results Includes assessments of more than 35 watchstanding plans that have been observed in civilian or military operations and/or studied in laboratories, and 331 technical references.

NA. Based on this initial work, the Army conducted a study of 1 wk of restricted sleep in 66 subjects with multiple measures of performance, termed the Sleep Dose-Response Study (SDR). The study was conducted aboard the USS Jason Dunham, a U.S. Navy destroyer operating in the vicinity of the Persian Gulf during the months of November and December 2012. Subjects were placed directly on the ship's deck, then on neoprene and rigid foam. Approximately 43% of the sample was overweight and 7% obese. ... Our results show that while underway, personnel receive much less sleep than the eight hours per day that is widely accepted as normal. For more information, contact John Pendleton at (202) 512-3489 or [email protected]. Both actigraphy and WristCare overestimated appreciably total sleep time (TST). The objective of this study is to assess the effect of ship departments on crew sleep patterns and psychomotor vigilance performance. Exempt Employees Each Sailor completed surveys detailing tasks in which they were engaged. The performance of the WristCare can be assumed to be well comparable to actigraphy in sleep/wake studies. 7-19 8-1 8-1 8-2 8-5 8-7 8-8 8-12 9-1 9-1 9-4 Appendix A Acronyms A-I Appendix B Glossary of Terms B-1 Appendix C Navy Standard Workweeks C-l More importantly, based on FAST results, most Sailors had predicted effectiveness levels lower than the predicted effectiveness level of the Navy Standard Workweek Model. More About The Navy and These Standards. The Navy expects these changes to keep factors current and accurate, thereby leading to more accurate and properly sized ship crews. his study compares the patterns of crew rest and sleep, psychomotor vigilance performance, and work demands/rest opportunities afforded by two different schedules, the 3-hour on/9-hour off (“3/9”) and the 6-hour on/6-hour off (“6/6”) watchstanding schedules. Publicly Released: Nov 19, 2020. This book is an annotated bibliography with more than 680 references. We postulate that concerns about the implementation of the 3/9 schedule may be ameliorated by adjusting sunlight exposure, providing sleep hygiene training, and by considering an alternative distribution of duties between watch sections to allow protected sleep times for those on night watch duty. Sleep ≥56 hours/7-day period USN does not have a regulation dedicated to work/rest times (except aviation) Results • Participants –Predominantly young (25.0±3.72 years of age) –Male (80%) –Enlisted (95%) • Crewmembers worked ≥14 hours/day for 21% of Crewmembers from the Reactor Department on the USS NIMITZ (N=117, 24.6±3.89 years old, 95 males, 109 enlisted, with 4.25±2.65 years of active duty) participated in this study. During the weigh-in portion of their semiannual Physical Readiness Test in Spring 2014, crewmembers of a U.S. Navy aircraft carrier were invited to complete an anonymous survey. Actigraphy results show that crewmembers were chronically sleep deprived, receiving on average 6.6 hours of daily sleep. Naval cohorts rely heavily on personnel to ensure the efficient running of naval organisations. School night sleep averaged 6.16 hours during HAB and 7.34 hours during EXT (p<.001). An Overview of Sleep Th is fi rst section of the chapter provides the rationale and scientifi c justifi cation for the entirety of the program of research that follows. The revised instruction further includes criteria and triggers that necessitate the updating of manpower requirements. Additionally, the January 2019 revision of OPNAVINST 1000.16L codified the process by which these standards should be revised. For example, it recommended a readjustment of the productive work factor, the creation of a new individual training component, and an increased allotment for service diversion activities in the workweek. This software is designed to help optimize the operational management of aviation ground and flight crews, but is not limited to that application.
