Resolving the (Apparent) Talker Recognition Paradox in Developmental Speech Perception

The infant literature suggests that humans enter the world with impressive built‐in talker processing abilities. For example, newborns prefer the sound of their mother's voice over the sound of another woman's voice, and well before their first birthday, infants tune in to language‐specific speech cues for distinguishing between unfamiliar talkers. The early childhood literature, however, suggests that preschoolers are unable to learn to identify the voices of two unfamiliar talkers unless these voices are highly distinct from one another, and that adult‐level talker recognition does not emerge until children near adolescence. How can we reconcile these apparently paradoxical messages conveyed by the infant and early childhood literatures? Here, we address this question by testing 16.5‐month‐old infants (N = 80) in three talker recognition experiments. Our results demonstrate that infants at this age have difficulty recognizing unfamiliar talkers, suggesting that talker recognition (associating voices with people) is mastered later in life than talker discrimination (telling voices apart). We conclude that methodological differences across the infant and early childhood literatures—rather than a true developmental discontinuity—account for the performance differences in talker processing between these two age groups. Related findings in other areas of developmental psychology are discussed.     

Using an Initial Clinical Interview to Assess the Coparenting Relationship: Preliminary Examples From the Supporting Father Involvement Program

The current study uses an initial intake interview as an assessment tool in the Supporting Father Involvement (SFI) intervention and considers it from a family systems theoretical perspective. SFI includes a 32-hour group for parents with young children that aims to reduce child abuse and promote family well-being through a curriculum focused on enhancing positive father involvement and coparenting. For this study, the initial clinical interview assessed partners’ synchronies and dissonance in parenting, coparenting, and relationship satisfaction domains. Using thematic analysis, we qualitatively analyzed interviews with 15 committed, heterosexual couples, exploring themes that correspond with higher versus lower couple satisfaction measured by the Quality of Marital Satisfaction Index. Results showed a strong concordance between partners’ satisfaction scores, with fathers less satisfied than mothers. Thematic differences between higher and lower satisfaction parents centered on approach to discipline, coparenting communication, and quality of support systems. The importance of father involvement and fathers as “learning” parents and coparents were recurring themes for mothers and fathers, especially among higher satisfaction couples. Higher substance abuse and employment/financial stress were indicative of lower satisfaction couples. Discussion reflects on the utility of an initial clinical interview as an assessment and intervention planning tool and future directions for research.     

Client and program factors associated with dropout from court mandated drug treatment

To examine why court mandated offenders dropout of drug treatment and to compare their characteristics, treatment experiences, perceptions, and outcomes with treatment completers, we analyzed self-reported and administrative data on 542 dropouts (59%) and 384 completers (41%) assessed for Proposition 36 treatment by thirty sites in five California counties during 2004. At intake, dropouts had lengthier criminal histories, lower treatment motivation, more severe employment and psychiatric problems, and more were using drugs, especially heroin. Relatively fewer dropouts received residential treatment and their retention was much shorter. A similar proportion of dropouts received services as completers and the mean number of services received per day by dropouts was generally more, especially to address psychiatric problems, during the first three months of treatment. The most commonly offender-reported reasons for dropout included low treatment motivation (46.2%) and the difficulty of the Proposition 36 program (20.0%). Consequences for dropout included incarceration (25.3%) and permission to try treatment again (24.0%). Several factors predicting drug treatment dropout were identified. Both groups demonstrated improved functioning at one-year follow-up, but fewer dropouts had a successful outcome (34.5% vs. 59.1%) and their recidivism rate was significantly higher (62.9% vs. 28.9%) even after controlling for baseline differences. Understanding factors associated with drug treatment dropout can aid efforts to improve completion rates, outcomes, and overall effectiveness of California's Proposition 36 program. Findings may also aid a broader audience of researchers and policy analysts who are charged with designing and evaluating criminal-justice diversion programs for treating drug-addicted offenders.     

Impact of T-ACASI on Survey Measurements of Subjective Phenomena

Numerous studies have shown that audio-computer-assisted self-interviewing (audio-CASI) and telephone audio-CASI (T-ACASI) technologies yield increased reporting of sensitive and stigmatized objective phenomena such as sexual and drug use behaviors. Little attention has been given, however, to the impact of these technologies on the measurement of subjective phenomena (attitudes, opinions, feelings, etc.). This article reports results for the seven subjective measurements included in the National STD and Behavior Measurement Experiment (NSBME). NSBME drew probability samples of USA and Baltimore adults (Ns = 1,543 and 744, respectively) and randomized these respondents to be interviewed by T-ACASI or telephone interviewer-administered questioning (T-IAQ). Response distributions for all subjective measurements obtained by T-ACASI diverge from those obtained by human telephone interviewers. For six of our seven ordinal-scaled measurements, this divergence involved shifting responses directionally along the ordinal scale, as opposed to a nondirectional redistribution among response categories. When interviewed by T-ACASI, respondents were more supportive of traditional gender roles and corporal punishment, less supportive of integrated neighborhoods and same-gender sex, and more likely to agree that occasional marijuana use is harmless and to describe themselves as attractive. The majority of these results suggest that telephone survey respondents may provide more "tolerant" and "socially liberal" responses to human interviewers than to a T-ACASI computer. Similarly, although the evidence is not entirely consistent, the impact of T-ACASI appears to increase with the social vulnerability of the population surveyed.     

“There Ain’t No Bond in Town Like There Used to Be”: The Destruction of Social Capital in the West Virginia Coalfields1

There is a paucity of research focusing on the circumstances that cause or contribute to a decline in social capital within communities. Furthermore, relatively few researchers employ qualitative methods in their studies of social capital, despite the multidimensional and many‐layered nature of this concept, characteristics that make social capital well suited for qualitative analysis. To address these two gaps in social capital research, I explore the mechanisms that have led to a depletion of social capital in the southern coal‐producing region of West Virginia. I examine whether the coal industry, which has caused bitter conflicts among residents over environmental degradation and union loyalties, has also undermined social capital in the region. My principal data include 40 semi‐structured, face‐to‐face interviews with randomly selected individuals in a coal‐mining town and a demographically similar non‐coal‐mining town in West Virginia. I analyze the experiences of residents in each town, assessing the qualitative differences in community and personal life associated with social capital. I find that the loss of social capital in the coal‐mining community has arisen through a combination of depopulation and the community‐wide conflict that arose when an anti‐union coal company bought out the union coal mine at which many in the community worked, challenging the union identity so engrained in this region.     

Racializing the "Social Development" State: Investing in Children in Aotearoa/New Zealand

This paper focuses on the claim that the child is emerging asa key figure of social governance. International studies suggestthat as liberal welfare states increasingly draw on social investmentdiscourse, the child—particularly the child-as-worker-in-becoming—hasemerged as an iconic figure. This has resulted in the childbecoming the central subject of social policies and programsand the focus of new spending priorities. In Aotearoa/New Zealand,however, the figure of the child is much less prominent thanelsewhere. Moreover, in the policies and programs of the NewZealand "social development" state, the child is often racializedby virtue of its location within specific family groupings andgeographical communities. In turn, this has implications forthe positioning of women. As we show, the child/mother who standsto benefit from the "investments" of social development in Aotearoa/NewZealand is actually more likely to be a Pkeh child/mother, whereasthe child/mother requiring continued programmatic interventionis more likely to be Mori or Pacific. This finding points tothe need for feminist scholars to examine further the complexinterpenetration of gender and race/ethnicity in the shapingof contemporary socio-political landscapes.     

Social services for sexual minority youth: Preferences for what,where, and how services are delivered

As part of an internet-based study to investigate experiences of sexual minority youth in the U.S., 544 youth, ages 14–19, were surveyed about their need for services, where they preferred to receive these services, and their preferred method of service delivery. The survey was anonymous and youth were recruited from LGBTQ-specific listservs and venues as well as through social networking sites as a way of reaching youth often not represented in LGBTQ surveys. Youth highly endorsed many types of services, settings, and modes of delivery. Some subgroup differences emerged. Transgender youth and those uncertain about their gender identity expressed stronger interest than others in services to address stress, family issues, and self-defense, and in receiving support and guidance from LGBTQ adults. Few differences in service preferences along demographic lines such as race/ethnicity emerged; however, African American youth were more likely than others to prefer services offered in a place of worship. Contrary to predictions, geographic and community variables were not related to service type, delivery format, or location preferences.     

Stepfamily childbearing in Sweden: quantum and tempo effects, 1950-99

Several studies have demonstrated that stepfamily couples have a higher risk of childbearing than couples in a stable union with the same total number of children. Analysing retrospective data from a nationally representative sample of Swedish adults, we find that the risk of a second or third birth is higher when it is the first or second child in a new union. We also find a faster pace of childbearing after stepfamily formation than after a shared birth. The risk of a second birth (in total) is only a little higher in the first two years after stepfamily formation than in the first two years after a shared birth, and thereafter the risk is lower for stepfamilies. The risk of a third birth (in total) is particularly high early in the stepfamily union and remains higher than that of couples with two shared children for at least five years. The stepfamily difference was lower after than before 1980, when the Swedish government introduced parental leave incentives for short birth intervals.     

Partners’ relationship quality and childbearing

This study examines the influence of partner relationship quality on childbearing. We are innovative in using relationship quality reports from both partners, drawing on the first and second wave of the Netherlands Kinship Panel Study. Thus, we can identify potential effects of discordant perceptions of the relationship on childbearing. We also pose a new hypothesis on the direction of the effect of relationship quality on fertility, predicting that medium levels of relationship quality result in the highest childbearing rates. Our results indicate that only women’s perceptions of relationship quality influence a first birth, whereas women’s and men’s perceptions affect second births. We do not find unique effects of disagreement in assessments of relationship quality; effects of partners’ perceptions are additive. Women reporting medium levels of relationship quality are most likely to have a(nother) child, whereas men with medium and high quality relationships are most likely to have a second child.     

Parameter identifiability in a class of random graph mixture models

We prove identifiability of parameters for a broad class of random graph mixture models. These models are characterized by a partition of the set of graph nodes into latent (unobservable) groups. The connectivities between nodes are independent random variables when conditioned on the groups of the nodes being connected. In the binary random graph case, in which edges are either present or absent, these models are known as stochastic blockmodels and have been widely used in the social sciences and, more recently, in biology. Their generalizations to weighted random graphs, either in parametric or non-parametric form, are also of interest. Despite these many applications, the parameter identifiability issue for such models has only been touched upon in the literature. We give here a thorough investigation of this problem. Our work also has consequences for parameter estimation. In particular, the estimation procedure proposed by Frank and Harary for binary affiliation models is revisited in this article.
