Is Teenage Sexual Behavior Rational?1

We evaluate the applicability of a decision making framework to the teenage contraceptive and sexual behavior of 1032 Philadelphia teenagers. We examine three reasons why the decision making perspective may not apply in this domain: (a) because the decision makers are teenagers, (b) because the decision concerns sexual behavior, and (c) because the costs of contraception and abstinence are immediate and certain, while the benefits are delayed and uncertain. Using multiple regression, we examine the predictors of sexual activity and contraceptive use. We find support for the decision making model in that the variables ordinarily included in decision analyses do significantly predict behavior. But respondents seem to place disproportionate weight on some considerations, such as the discomfort of using birth control, and very little on others, such as the effectiveness of birth control or their attitude toward motherhood.     

Drawing the line: How the workplace shapes the naming of sexual harassment

Although sexual harassment naming – the process by which individuals identify and label experiences as sexual harassment – is key to tackling the problem of workplace sexual harassment, extant research focused on individual differences has explained a limited amount of variance in individuals’ propensity to name. We push this research in a new direction, drawing on institutional theory and strategic human resource management to identify workplace contextual factors that influence individuals’ propensity to name sexual harassment. Surveying 408 employed adults, we find that current employment in an industry with a high prevalence of sexual harassment reduces individuals’ likelihood of identifying scenarios as sexual harassment. Further, prior work experience in highly sexually harassing industries has a lasting negative effect on individuals’ propensity to name. In contrast, we show that individuals’ propensity to identify sexual harassment is greater when they perceive that their organization has implemented more HR practices supporting a climate for naming and that these HR practices can actually reduce the negative effect of current employment in a highly sexually harassing industry. Critically, by demonstrating that changing industry norms or adopting specific HR practices can shift individual naming of sexual harassment, we offer new avenues for sexual harassment prevention.     

Pilot test of a measure to assess clients’ perceptions of their home visitors

Home visiting services for caregivers of infants and young children have been found to be an effective method for promoting child development. Unfortunately, such services suffer from high rates of attrition, suggesting the need to identify factors related to client retention in services. Research has indicated that the client-provider relationship is an important predictor of client retention in home visiting services; however, measures to assess this relationship are limited. This study reports on a pilot test of the Client Perceptions of Home Visitors Questionnaire, developed to assess home visiting clients’ perceptions of their relationship with their home visitor. The measure was completed by 39 diverse home visiting clients during pregnancy in a midwestern town in the United States. The scale was found to have good internal consistency. Validity analyses found that the scale was positively associated with client satisfaction with services and perceived provider cultural sensitivity. The scale was also positively associated with retention in services at an 8-month follow-up. Additional research should examine the measure's psychometrics with larger samples.     

Internalized transphobia: Exploring perceptions of social messages in transgender and gender-nonconforming adults

Background: Transgender and gender nonconforming (TGNC) individuals encounter a variety of minority stressors that have yet to be fully articulated or explored within the research literature. The purpose of this study is to better understand internalized stigma—the experience of accepting and internalizing negative social messages and experiences about one's identity—an underexplored minority stressor for TGNC people.

Method: We conducted in-depth interviews with 30 diverse TGNC participants using consensual qualitative research (CQR) methodology.

Results: Following data saturation and analysis, six distinct themes emerged across participants: (1) TGNC identities are regarded negatively by society; (2) social messages are perceived as originating from the media and religious ideology; (3) TGNC individuals report emotional distress; (4) negative self-perceptions in response to social messages; (5) TGNC individuals report resilience processes in response to negative social messages; and (6) social messages are perceived generally to differentially impact TGNC people of color.

Conclusion: Findings highlight the common experience of encountering social marginalization for TGNC individuals. Structural interventions that target pervasive sociocultural messages regarding TGNC identities are warranted.     

The Principle of Summation

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

THE NATURE OF HOPE

Both traditional accounts of hope and some of their recent critics analyze hope exclusively in terms of attitudes that a hoper bears towards a hoped-for prospect, such as desire and probability assignment. I argue that all of these accounts misidentify cases of despair as cases of hope, and so misconstrue the nature of hope. I show that a more satisfactory view is arrived at by noticing that in addition to the aforementioned attitudes, hope involves a characteristic attitude towards an external factor, on whose operation the hoper takes the prospect's realization to depend causally.     

The Influence of Children on Their Parents’ Values

Many parents report that their values are influenced by their children. However, few studies provide direct evidence regarding child–parent value transmission. We review this evidence and propose five main processes of child influence: (i) Passive child influences, causing change in parental values by the mere presence or development of children; (ii) Active child influences, due to children directly attempting to influence their parents’ opinions or providing parents with relevant information; (iii) Differentiation, the emergence of a distinction between parents’ own personal values and their socialization values; (iv) Reciprocal influences; in which parents’ and children’ influences are intertwined; and (v) Counter‐influences, in which parental values change in a direction opposite to that of children's values. A study on child influence illustrates some of these processes. The roles of migration, aging, and parent and child characteristics in child‐to‐parent influences are discussed.     

Indiscriminability as Indiscernibility by Default

Most solutions to the sorites reject its major premise, i.e. the quantified conditional . This rejection appears to imply a discrimination between two elements that are supposed to be indiscriminable. Thus, the puzzle of the sorites involves in a fundamental way the notion of indiscriminability. This paper analyzes this relation and formalizes it, in a way that makes the rejection of the major premise more palatable. The intuitive idea is that we consider two elements indiscriminable by default, i.e. unless we know some information that discriminates between them. Specifically, following Rough Set Theory, two elements are defined to be indiscernible if they agree on the vague property in question. Then, a is defined to be indiscriminable from b if a is indiscernible by default from b. That is to say, a is indiscriminable from b if it is consistent to assume that a and b agree on the relevant vague property. Indiscernibility by default is formalized with the use of Default Logic, and is shown to have intuitively desirable properties: it is entailed by equality, is reflexive and symmetric. And while the relation is neither transitive nor substitutive, it is “almost” substitutive. This definition of indiscriminability is incorporated into three major theories of vagueness, namely the supervaluationist, epistemic, and contextualist views. Each one of these theories is reduced to a different strategy dealing with multiple extensions in Default Logic, and the rejection of the major premise is shown to follow naturally. Thus, while the proposed notion of indiscriminability does not solve the sorites by itself, it does make the unintuitive conclusion of many of its proposed solutions—the rejection of the major premise—a bit easier to accept.     

A Measure for the Reliability of a Rating Scale Based on Longitudinal Clinical Trial Data

A new measure for reliability of a rating scale is introduced, based on the classical definition of reliability, as the ratio of the true score variance and the total variance. Clinical trial data can be employed to estimate the reliability of the scale in use, whenever repeated measurements are taken. The reliability is estimated from the covariance parameters obtained from a linear mixed model. The method provides a single number to express the reliability of the scale, but allows for the study of the reliability’s time evolution. The method is illustrated using a case study in schizophrenia. The authors are grateful to J&J PRD for kind permission to use their data.

Prosocial behavior from early to middle childhood: genetic and environmental influences on stability and change

Prosocial behavior is important for the functioning of society. This study investigates the extent to which environment shared by family members, nonshared environment, and genetics account for children's prosocial behavior. The prosocial behavior of twins (9,424 pairs) was rated by their parents at the ages of 2, 3, 4, and 7 and by their teachers at age 7. For parent ratings, shared environmental effects decreased from .47 on average at age 2 to .03 at age 7, and genetic effects increased from .32 on average to .61. The finding of weak shared environmental effects and large heritability at age 7 was largely confirmed through the use of teacher ratings. Using longitudinal genetic analyses, the authors conclude that genetic effects account for both change and continuity in prosocial behavior and nonshared environment contributes mainly to change.
