Positive impact of sunlight exposure on mental health in a naval population.

Naval shipboard operations impose numerous environmental and occupational stressors, which can adversely affect mental and physical health outcomes. Moreover, this operational setting also complicates the implementation of countermeasures to protect personnel from these stressors. Thus, any easily accessible or modifiable protective factors should be explored further for their potential to support the health of military personnel.

Steps toward developing a comprehensive fatigue monitoring and mitigation solution: perspectives from a cohort of United States Naval Surface Force officers.

Study Objectives: This study analyzed fatigue and its management in US Naval Surface Force warships, focusing on understanding current practices and barriers, and examining the influence of organizational and individual factors on managing chronic fatigue. Furthermore, this study explored the impact of organizational and individual factors on fatigue management.

Methods: As part of a larger study, 154 naval officers (mean ± standard deviation; 31.

Organizational caring as a predictor of good mental health in an operational naval environment.

Military service members encounter numerous stressors that adversely affect their mental health. These pervasive stressors emphasize the need to continually surveil, identify, and mitigate negative factors before they can produce cascading consequences for the individual. The present study utilized a large sample ( = 13,666) to identify several factors that might lead individuals to have poor mental health days in an austere naval operating environment.

Psychological endurance: how grit, resilience, and related factors contribute to sustained effort despite adversity.

Many concepts describe how individuals sustain effort despite challenging circumstances. For example, scholars and practitioners may incorporate discussions of grit, hardiness, self-control, and resilience into their ideas of performance under adversity. Although there are nuanced points underlying each construct capable of generating empirically sound propositions, the shared attributes make them difficult to differentiate.

Selecting senior leaders in the public sector: Challenges and best practices.

Although the careful assessment and selection of leaders are important for an organization to succeed, selecting senior leaders can prove paramount given their potential to impact the entire organization. While private sector businesses expend substantial resources to recruit and retain senior leaders, the public sector struggles to do so, which in turn impacts the attitudes and retention of employees throughout the enterprise. For example, a recent survey of federal employees in the United States found that most respondents did not believe their senior leaders generated high levels of motivation and commitment in the workforce.

Deficits in Visual Processing During Hypoxia as Evidenced by Visual Mismatch Negativity.

Hypoxia is an ever-present threat in tactical aviation and gained recent attention due to its putative role in physiological episodes. Previous work has demonstrated that hypoxia negatively impacts a variety of sensory, cognitive, and motor systems. In particular, the visual system is one of the earliest systems affected by hypoxia.

Impaired Sensory Processing During Low-Oxygen Exposure: A Noninvasive Approach to Detecting Changes in Cognitive States.

The ability to detect novelty in our environment is a critical sensory function. A reliable set of event-related potentials (ERP), known as the auditory deviance response (ADR), are elicited in the absence of directed attention and indexes functionally relevant networks. The ADR consists of three peaks: mismatch negativity (MMN), P3a, and reorienting negativity (RON) that are sequentially evoked in response to unattended changes in repetitive background stimulation.
