Physiological Regulation and Fearfulness as Predictors of Young Children's Empathy‐related Reactions

Indices of physiological regulation (i.e., resting respiratory sinus arrhythmia [RSA] and RSA suppression) and observed fearfulness were tested as predictors of empathy‐related reactions to an unfamiliar person's simulated distress within and across 18 (T1, N = 247) and 30 (T2, N = 216) months of age. Controlling for T1 helping, high RSA suppression and low fearfulness at T1 predicted T2 helping. In a structural model, empathic concern was marginally positively related to resting RSA at both assessments whereas personal distress was related to RSA suppression within time (marginally positively at T1 and significantly negatively at T2). Fearfulness was associated with self‐oriented, distress‐related reactions within time. Comfort seeking (an index of personal distress) declined in mean level with age whereas helping increased, and both behaviors exhibited differential continuity (as did resting RSA). Individual, as well as developmental, differences in the types of reactions that young children exhibit when witnessing others' suffering and distress were discussed.     

Step-Down Multiple Comparison Procedures Using Medians and Permutation Tests

Richter and McCann (2007 Richter , S. J. , McCann , M. H. ( 2007 ). Multiple comparisons using medians and permutation tests . Journal of Modern Applied Statistical Methods 6 ( 2 ): 399 – 412 . [Google Scholar]) presented a median-based multiple comparison procedure for assessing evidence of group location differences. The sampling distribution was based on the permutation distribution of the maximum median difference among all pairs, and provides strong control of the FWE. This idea is extended to develop a step-down procedure for comparing group locations. The new step-down procedure exploits logical dependencies between pairwise hypotheses and provides greater power than the single-step procedure, while still maintaining strong FWE control. The new procedure can also be a more powerful alternative to existing methods based on means, especially for heavy-tailed distributions.     

Caregiving Youth Knowledge and Perceptions of Parental End-of-Life Wishes in Huntington’s Disease

Knowledge of patient end-of-life (EOL) wishes and discussions are vital for family caregivers, including children and youth who may be in caregiving roles (“young carers” or “caregiving youth”). However, little is known about caregiving youth awareness and perceptions of EOL issues. This study sought to explore caregiving youth knowledge of EOL wishes and their willingness for EOL discussions. Face-to-face interviews with 40 caregiving youth ages 10–20, who have a parent with Huntington’s disease (HD), provided information about their knowledge of the presence of their ill parent’s living will (LW) and durable power of attorney for health care (DPAHC), and willingness to talk with the parent about EOL choices and possibility of death. Less than one-half of the participants were aware of the parent’s LW or DPAHC. Content analysis revealed themes in reasons to want or not want EOL discussion with the parent: respect for the parent’s wishes, caregiving youths’ opinion not valued, and avoidance of EOL issues. Themes also included reasons to not want discussion with the parent about possibility of death: protecting the parent, parent in denial, parent not ready, and realization of the terminal outcome. Findings suggest HD patients and their caregiving youth need support for open EOL discussions, and could benefit from educational programs and support groups around EOL issues.     

Implementation fidelity in a teacher-led alcohol use prevention curriculum

There is now ample evidence that teachers tend to make substantial modifications to both the prescribed content and methods of the curricula they administer, and that such modifications are likely to attenuate curricula effects. We examine the fidelity with which teachers implement "Protecting You, Protecting Me," an underage alcohol use prevention curriculum. Findings suggest that while teachers attempted to implement most sections of a lesson, the lessons taught were consistently--and often extensively--adapted. We conclude that since teachers are likely to continue to modify lessons, curriculum developers and trainers should enhance their understanding of how prevention curricula are taught under real world conditions, help teachers to reinforce key curriculum concepts, and consider modifying those curricular sections that teachers are adapting with greatest frequency.     

Of worms, flies, dwarfs, and things that go bump in the night

Studies over the past several years have found that antagonism of the insulin/insulin-like growth factor 1 (IGF-1) signaling pathway increases life-span in Caenorhabditis elegans and Drosophila. However, a persistent problem in these studies is the fact that the genetic mutation has effects on the development of the organism as well as on reproductive function. These effects act as potential confounding variables that complicate the interpretation of results. Kenyon and colleagues circumvent these issues by suppressing the insulin/IGF-1-like daf-2 signaling pathway at specific stages in the life-span of C. elegans. The results of their investigation challenge our understanding of the evolution of aging and provide opportunities for future studies in mammalian models.     

Is the Person-Affecting Intuition Paradoxical?

This article critically examines some of the inconsistency objections that have been put forward by John Broome, Larry Temkin and others against the so-called "person-affecting," or "person-based," restriction in normative ethics, including "extra people" problems and a version of the nonidentity problem from Kavka and Parfit. Certain Pareto principles and a version of the "mere addition paradox" are discussed along the way. The inconsistencies at issue can be avoided, it is argued, by situating the person-affecting intuition within a non-additive form of maximizing consequentialism – a theory which then competes with such additive, or aggregative, forms of maximizing consequentialism as "totalism" and "averagism."     

Using the Internet and Email for Health Purposes: The Impact of Health Status*

Objective. Increasingly, people use the Internet and email for health purposes; however, we know little about whether this varies by health status. This study examines whether sick or healthy people are more likely to access the Internet, conduct online health searches, and exchange emails regarding health issues. Methods. We conduct multivariate analysis on a random sample of 2,038 adults. Results. Despite greater Internet access, respondents in excellent/good health are less likely to say they conduct online health searches because they have no health concerns or are satisfied with other health sources. In contrast, sick and disabled respondents are more likely to seek medical information online, and do so more frequently. They are also more likely to exchange health emails with friends and physicians. Conclusions. Practitioners especially need to educate their sicker patients about the uneven quality of online health information since they are more likely than healthier patients to conduct online health searches.
