Dependence function for continuous bivariate densities

The notion of cross-product ratio for discrete two-way contingency table is extended to the case of continuous bivariate densities. This results in the “local dependence function” that measues the margin-free dependence between bivariate random variables. Properties and examples of the dependence function are discussed. The bivariate normal density plays a special role since it has constant dependence. Continuous bivariate densities can be constructed by specifying the dependence function along with two marginals in analogy to the construction of two-way contingency tables given marginals and patterns of interaction. The dependence function provides a partial ordering on bivariate dependence.     

Adolescent Weblog Use: Risky or Protective?

Weblogs, or personal websites updated in time-based fashions, are common media used for expressing thoughts and networking socially online (Lenhart et al. in Teens and social media, Pew Internet and American Life Project, Washington, DC, 2007). This qualitative study describes the content of 100 adolescent weblog users’ communications through a risk and resilience framework. These users primarily utilized weblogs for community building, as most of their postings involved communications designed to foster and nurture relationships with peers via the weblog. The majority of the content posted involved the discussion of common prosocial behaviors, such as doing homework, hanging out with friends, or planning for events such as dances. A surprisingly small amount of weblog content included text about risk factors and related problem behaviors. Findings are described in relation to adolescent use of the Internet. Specific implications are drawn for social workers and other professionals involved in youth work.     

A Qualitative Analysis of College Women's Leaving Processes in Abusive Relationships

Abstract

Objective: This study assessed the process of leaving an abusive dating relationship utilizing a qualitative design. Methods: Participants included 123 college women in abusive dating relationships who participated at the beginning and end of a 10-week academic quarter. Results: Qualitative content analyses were used to analyze the transcribed responses to an open-ended question about women's leaving processes over the interim period. A variety of categories and themes emerged for women in different stages of the leaving process, consistent with the Transtheoretical Model of Change and Investment Model. Data also underscored women's lack of acknowledgment, minimization, and normalization of abuse. Conclusions: These data demonstrate the importance of dating violence intervention and prevention programming on college campuses and offer information that may be useful to college health providers who assist women in abusive dating relationships.     

Hindsight,foresight and insight: The challenges of longitudinal qualitative research

This paper describes a UK based longitudinal qualitative study following approximately 100 young people over 9 years. It provides an overview of the research design, methods of data collection and analysis as well as reflecting on the strengths and weaknesses of the strategies employed. We focus on the value of a devolved research design, complementary cross-section and temporal analytic approaches and the effects of being involved in a longitudinal study on researchers and participants. The paper aims to contribute to a growing understanding of the practical, ethical and epistemological challenges presented by longitudinal qualitative methods, and highlights those challenges that are specific to this method as well as those which are amplified by this kind of approach.     

Potential Selective Responding in a Parent Questionnaire Study of Post-Institutionalized Children

This study assesses selective responding in a single wave of data collection and a four-wave study. Participants were 121 parents of post-institutionalized children, identified as “never responders,” “previous responders,” or “wave 4 responders.” Parents evaluated their adopted child's family, school, peer, and behavioral adjustment. Children (47% male) were 2 to 20 years old (M = 10.79, SD = 4.59) and adopted between 5 and 54 months of age (M = 15.49, SD = 9.94). Within a single wave of data collection, no evidence suggested that selective responding contributes much bias. Over a multi-wave study, however, results may under-represent adjustment difficulties.     

Reflexivity

Just as the concept paradigmenergized the human sciences in spite of its manydefinitions and uses, so now does the conceptreflexive seem to be of increasingsalience, again with many definitions and uses. It is argued thatreflexivity, as a fundamental human quality underliesvarious attempts to understand and intervene in humanrelationships. By juxtaposing paradigms, reflexivity, and therapeutic progression it is possible toset out several types of reflexivity, some relativelyself-contained and others at the edge of our possibleknowledges.     

Positive and negative affect: A maximum-likelihood approach

Using the LISREL maximum-likelihood program, the relation between Bradburn's positive affect and negative affect scales is examined for three age groups of adults. It is found that (a) unequal item loadings fit significantly better than equal item loadings; (b) the best-fitting loadings for the elderly are significantly different from those of the non-elderly; (c) the positive and negative affect scales are substantially correlated and (d) correlations with related variables are stronger when positive and negative affect scales are formed by maximum-likelihood loadings rather than by unit loadings. Given the widespread use of Bradburn's scales, implications of these results for subjective well-being are discussed.     

The social context of hoarding behavior: Building a foundation for sociological study

This paper aims to build a foundation from which sociologists can effectively address hoarding as a social problem embedded in a wider economic, cultural, and historic context. By focusing on practices of consumerism, interior design, collecting and waste disposal, we can see how socially constructed attitudes toward objects are linked with three primary hoarding behaviors: the acquisition of objects, clutter within the home, and difficulty discarding items. The transformation of shopping into a leisurely pastime has created a cultural context in which the acquisition of objects is normal and expected. Arrangement of objects within the home can be used to create of a sense of class membership, and collecting as a hobby and a lifestyle has been socially and economically encouraged since the late 1800s. Finally, a look at disposal practices reveals that the way we get rid of objects can be just as socially dictated as the way we use them. The behaviors associated with hoarding have been historically developed and are actively encouraged in contemporary western society. By examining the social context of hoarding behaviors, we can move toward an understanding of the ways that hoarders and nonhoarders alike navigate the social and economic landscape using material culture.     

Getting Out and About: The Relationship Between Urban Form and Senior Travel Patterns

As the overall U.S. population expands outward from the central city and core suburbs and as people age in place, more seniors will reside in suburban and exurban locations. This research seeks to determine whether older adults who live in areas with differing urban forms experience travel pattern variations under controls for other factors related to travel. We analyzed data from a telephone survey of a random sample of seniors aged 75 years and older and we employed a unique approach for establishing the urban form of their residential settings. The results show that urban form does influence travel patterns, including the number of trips and transportation mode, and suggest that the construction of compact, mixed-use communities where today's older adults can age in place may be part of the solution to addressing the mobility needs of our aging population.
