Nanoethics—A Collaboration Across Disciplines

The field of nanoscience and nanotechnology is expanding rapidly, promising great benefits for society in the form of better medicine, more efficient energy production, new types of materials, etc. Naturally, in order for the science and technology to live up to these promises, it is important to continue scientific research and development, but equally important is the ethical dimension. Giving attention to the social, ethical and legal aspects of the field, among others, will help in developing a fully responsible—and thereby capable—science and technology. Nanoethics has emerged as a field concerned with such ethical issues related to nanoscience and nanotechnology. Even though this field is relatively new, a significant amount of literature has already been published. This paper focuses on three of the major issues which are discussed in the literature of nanoethics, and also points to a certain bias in this literature. Each quite different in nature, these issues are: (1) The naming and (2) the timing of and approach to the field, as well as (3) the issue of safety. As will be seen, these issues are almost exclusively discussed by ethicists, (throughout the article, the term’ethicist’ is used in a broad definition covering philosophers, social and political scientists as well as philosophers of science) thus having no direct influence on the work being carried out by scientists. One can argue, therefore, that this bias creates a distortion of the ethical debate, making it insufficient and misleading. Ultimately, this bias is caused by the lack of communication and collaboration between ethicists on the one hand, and nanoscientists on the other. Thus, an argument is made for the different disciplines to begin collaborating, so as to more effectively and responsibly develop the field of nanoscience.     

Does Happiness Predict Medication Adherence among African Americans with Hypertension?

Poor medication adherence is a leading cause of excessive cardiovascular morbidity among African Americans. Many adherence-promoting interventions have addressed economic barriers, improved the patient-provider relationship, simplified regimens, and used reminder systems; however, the problem of low adherence remains intractable. Meanwhile, positive psychological attributes that might serve to promote medication adherence have not been fully explored. To address this gap, we examined the association between happiness and medication adherence among low-income African Americans with hypertension treated in a safety-net setting. Data were obtained from the Alabama Collaboration for Cardiovascular Equality, 2007?C2008. Happiness was measured using the 4-item scale of Lyubomirsky and Lepper; low, moderate, and high happiness were defined by tertiles because of the non-normal distribution. Medication adherence was assessed with the Morisky Medication Adherence Scale. Associations were quantified with ordinal logistic regression. Our sample of 573 African Americans was 71.6?% female and had an average age?±?SD of 53.6?±?9.7?years and a median happiness score of 5.2. Compared to participants with low happiness, the odds (OR; 95?% CI) of being in a better medication adherence category were greater for those with moderate (1.53; 1.02?C2.27) and high (2.26; 1.52-3.37) happiness, after adjusting for age, sex, income, education, and difficulty paying for medical care. Within this cohort of low-income African Americans with hypertension, participants with greater happiness exhibited better medication adherence. Although one interpretation of our study is that more adherent patients are naturally happier, our findings raise the possibility that adding happiness-boosting components may increase the effectiveness of more traditional adherence interventions.     

Limits of focused attention in three-dimensional space

The present experiment examined the shape of the attentional gradient in three-dimensional space. Subjects performed a response-compatibility task in which they were instructed to respond to a centrally located target and ignore flanking distractors. The irrelevant distractors were presented at combinations of seven different depths, three different horizontal separations, and three different vertical separations relative to the target. Depth was varied in a stereoscopic display viewed through polarized glasses. Overall, the size of the response-compatibility effect decreased with increased separation in all three dimensions. Interestingly, the response-compatibility effect was larger for horizontal separations than for vertical separations and was larger for crossed disparities than for uncrossed disparities. The results suggest an elliptical focus of attention, with steeper gradients in the vertical dimensions than in the horizontal dimensions. In addition, the results suggest, along the vertical dimension, a steeper gradient for objects located beyond the focus of attention relative to that for objects located between the observer and the focus of attention.     

The judgment-choice discrepancy: Noncompatibility or restructuring?

The study examines the relative merits of a noncompatibility and a restructuring explanation of the recurrent empirical finding that a prominent attribute looms larger in choices than in judgments. Pairs of equally attractive options were presented to 72 undergraduates who were assigned to six conditions in which they performed (1) only preference judgments or choices, (2) preference judgments or choices preceded by judgments of attractiveness of attribute levels, or (3) preference judgments or choices accompanied by think-aloud reports. The results replicated the prominence effect for choices, but a prominence effect was also found for preference judgments. In accordance with the restructuring explanation, the think-aloud protocols indicated that options were more often restructured in choices than in preference judgments. However, restructuring could not explain the prominence effect observed for preference judgments. A modified compatibility hypothesis is offered as an alternative explanation.     

Who is Afraid of Figure of Speech?

Aristotle's illustrations of the fallacy of Figure of Speech (or Form of Expression) are none too convincing. They are tied to Aristotle's theory of categories and to peculiarities of Greek grammar that fail to hold appeal for a contemporary readership. Yet, upon closer inspection, Figure of Speech shows many points of contact with views and problems that inhabit 20th-century analytical philosophy. In the paper, some Aristotelian examples will be analyzed to gain a better understanding of this fallacy. The case of the Third Man argument and some modern cases lend plausibility to the claim that Figure of Speech is of more interest as a type of fallacy than has generally been assumed. Finally, a case is made for the view that Figure of Speech, though listed among the fallacies dependent upon language, is not properly classified as a fallacy of ambiguity. More likely, it should be looked upon as a type of non sequitur. This has important consequences for the profile of dialogue associated with this fallacy.     

Running on Empty: The Effects of Aggregate Travel Stress on Team Performance

Purpose

In this study, we explore the effects of travel on performance at the team level using conservation of resources (COR) theory as an explanatory mechanism. We investigate the effects of aggregate travel stress, which we define as the accumulated strain experienced by a team when traveling, on key components of team functioning and performance including team task performance, team concentration level, and counterproductive work behaviors (CWB).

Design/Methodology/Approach

We analyze 3054 games played in the National Football League across six seasons using multilevel structural equation modeling. Replicating our findings, we also analyzed an additional 11,802 games played in the National Basketball Association across five seasons.

Findings

Aggregate travel stress, as a latent construct, negatively impacts team task performance and team concentration level. Team concentration partially mediates the relationship between aggregate travel stress and CWB.

Implications

Findings suggest that travel has a deleterious effect on various forms of team functioning and performance. As a result, organizations and leaders need to be aware of the potential side effects of travel, and researchers need to further incorporate travel into models and examinations of workplace stress.

Originality/Value

This is the first study to provide a theoretically driven investigation of the effects of business travel on team outcomes and to apply COR theory to team-level phenomena. Results put forth offer a more nuanced understanding of the effects of travel as well as open up new avenues of exploration for COR theory.

     

Chronicity, severity, and timing of maternal depressive symptoms: relationships with child outcomes at age 5

The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems.
