A Qualitative Exploration of Sleep Habits and Intervention Needs Among Youth with Cystic Fibrosis

Evidence suggests that individuals with Cystic Fibrosis (CF) experience difficulties with sleep architecture and hygiene, although research is limited. There are currently no behavioral sleep interventions for youth with CF. The current study used qualitative methods to understand sleep needs and concerns among youth with CF, as well as to obtain feedback about potentially useful behavioral sleep intervention strategies. Semi-structured interviews were conducted with youth with CF between the ages of 11–17 and their parents. Themes were extracted from the data and will be used to inform the development of a brief behavioral sleep intervention for youth with CF. Youth and their parents described several CF-specific sleep concerns, often related to respiratory symptoms, and a number of strategies used to manage these concerns. They also described concerns that apply to the general population, including pervasive use of technology around bedtime. Many evidence-based behavioral sleep intervention strategies are acceptable to youth with CF, although modifications are appropriate to reduce time burden and address CF-specific needs. Youth with CF experience a number of disease-specific and more generalized sleep concerns which are likely amenable to behavioral intervention. Results from this study will be used to inform the development of a brief behavioral sleep intervention for youth with CF.

     

Evolution of Different Dual-use Concepts in International and National Law and Its Implications on Research Ethics and Governance

This paper provides an overview of the various dual-use concepts applied in national and international non-proliferation and anti-terrorism legislation, such as the Biological and Toxin Weapons Convention, the Chemical Weapons Convention and United Nations Security Council Resolution 1540, and national export control legislation and in relevant codes of conduct. While there is a vast literature covering dual-use concepts in particular with regard to life sciences, this is the first paper that incorporates into such discussion the United Nations Security Council Resolution 1540. In addition, recent developments such as the extension of dual-use export control legislation in the area of human rights protection are also identified and reviewed. The discussion of dual-use concepts is hereby undertaken in the context of human- and/or national-security-based approaches to security. This paper discusses four main concepts of dual use as applied today in international and national law: civilian versus military, peaceful versus non-peaceful, legitimate versus illegitimate and benevolent versus malevolent. In addition, the usage of the term to describe positive technology spin-offs between civilian and military applications is also briefly addressed. Attention is also given to the roles civil society and research ethics may play in the governance of dual-use sciences and technologies.     

American-Japanese cultural differences in judgements of emotional expressions of different intensities

Although research has generated a wealth of information on cultural influences on emotion judgements, the information we have to date is limited in several ways. This study extends this literature in two ways, first by obtaining judgements from people in two cultures of expressions portrayed at different intensity levels, and second by incorporating individual level measures of culture to examine their contribution to observed differences. When judging emotion categories in low intensity expressions, American and Japanese judges see the emotion intended at above-chance rates, albeit lower than when judging high intensity faces. Also, American and Japanese intensity ratings of external displays and internal experiences differ dramatically for low intensity expressions compared to high intensity faces. Finally, the two cultural dimensions measured in this study—individualism versus collectivism (IC) and status differentiation (SD)—accounted for almost all of the variance in the observed differences. These findings are discussed in terms of their underlying possible mechanisms, and future research possibilities.     

The influence of linguistic labels on source‐monitoring decisions

Three studies explored the extent to which people use various object features, including linguistic label, shape, and category membership, to make decisions about the source of their memories. To isolate the influence of each feature, we used items that were related in the following four ways: as synonyms, as similar in shape and category membership, as homographs, or as unrelated. Participants read sentences and either saw or imagined a picture of the critical word's referent. Experiment 1 showed that participants committed more source errors for synonyms (e.g., rabbit and bunny) than for objects that were conceptually and perceptually similar (e.g., doughnut and bagel), which produced more errors than unrelated items. However, there was no effect of label, as people did not have more errors for homographs (e.g., baseball bat and flying bat) than unrelated items. In Experiment 2, presenting the critical word at study was not sufficient to lead people to use an item's label to make source decisions. However, Experiment 3 showed more source errors for homographs than unrelated pairs when semantic context was minimised at study, suggesting that people can use linguistic labels to make source decisions when other information is unavailable.     

The Problem of Enhanced Control

I defend (metaphysical) ground against recent, unanswered objections aiming to dismiss it from serious philosophical inquiry. Interest in ground stems from its role in the venerable metaphysical project of identifying which facts hold in virtue of others. Recent work on ground focuses on regimenting it. But many reject ground itself, seeing regimentation as yet another misguided attempt to regiment a bad idea (like phlogiston or astrology). I defend ground directly against objections that it is confused, incoherent, or fruitless. This vindicates the very attempt to regiment ground. It also refocuses our attention on the genuine open questions about ground and away from the distracting, unpersuasive reasons for dismissing them.     

Spouse and Family Functioning Before and After a Marine’s Suicide: Comparisons to Deaths by Accident and in Combat

The impact of service member suicides on families is not well understood. Civilian studies have demonstrated that family survivors of suicide deaths experience complicated grief, feel guilt and shame, and often do not receive sufficient social support. In this exploratory study, spouse survivors of Marines who died by suicide (N = 17), accident (N = 19), and in combat (N = 34) retrospectively reported on their immediate pre- and postmortem and current personal and family functioning. Nonparametric analyses revealed that several between-group differences existed. Observation of the means suggested that the spouses and families of Marines who died by suicide exhibited significantly poorer pre- and postmortem functioning compared with those whose spouses died in combat. Specific challenges included low family cohesion, high family conflict, perceived stigma, and shame. There were no differences in current spouse or family functioning, and there was weak evidence for posttraumatic growth among surviving spouses of those dying by suicide. These results should be considered preliminary and interpreted with caution given several methodological challenges.     

Measuring Collective Efficacy Among Children in Community-based Afterschool Programs: Exploring Pathways toward Prevention and Positive Youth Development

Collective efficacy refers to a perceived sense of connectedness and willingness to intervene among youth, and is a potential aspect of positive youth development (Larson in Am Psychol 55:170–183, 2000; Lerner et al. in Child Dev 71:11–20, 2000; Sampson et al. in Science 277:918–924, 1997). Theoretically, those who feel connected to a group that is empowered to positively influence the behavior of their peers may demonstrate fewer problem behaviors. Few studies, however, have measured the impact of youth perceptions of collective efficacy. As a relatively new child-related research topic, there is much to be learned. One contribution to the foundation of this research agenda begins by evaluating the reliability and validity of a measure of collective efficacy with elementary children attending community-based afterschool programs. This paper describes the internal consistency reliability and various indicators of construct and concurrent validity of the Collective Efficacy Among Children Scale. The measure was found to have high internal consistency reliability. Construct validity was tested using exploratory factor analyses of collective efficacy including the dimensions of willingness to intervene and cohesion found in previous research (Sampson et al. in Science 277:918–924, 1997). Concurrent validity assessed relations between the scale and other measures in theoretically congruent ways. Using Hierarchical Linear Models to account for children's nestedness in after-school programs, connectedness was found to be more related to emotional adjustment, particularly children’s prosocial attitudes (caring about others and sharing). Children’s perception of the willingness of the group to intervene was found to be related to less problem behavior, (i.e. smoking tobacco, drinking alcohol, vandalism, and stealing). The implications suggest that future research should further explore children’s collective efficacy, and ways to foster its development in youth-serving afterschool settings.     

The testing effect in free recall is associated with enhanced organizational processes

In two experiments with categorized lists, we asked whether the testing effect in free recall is related to enhancements in organizational processing. During a first phase in Experiment 1, subjects studied one list over eight consecutive trials, they studied another list six times while taking two interspersed recall tests, and they learned a third list in four alternating study and test trials. On a test 2 days later, recall was directly related to the number of tests and inversely related to the number of study trials. In addition, increased testing enhanced both the number of categories accessed and the number of items recalled from within those categories. One measure of organization also increased with the number of tests. In a second experiment, different groups of subjects studied a list either once or twice before a final criterial test, or they studied the list once and took an initial recall test before the final test. Prior testing again enhanced recall, relative to studying on the final test a day later, and also improved category clustering. The results suggest that the benefit of testing in free recall learning arises because testing creates retrieval schemas that guide recall.
