Laughter in Conversation: Features of Occurrence and Acoustic Structure

Although human laughter mainly occurs in social contexts, most studies have dealt with laughter evoked by media. In our study, we investigated conversational laughter. Our results show that laughter is much more frequent than has been described previously by self-report studies. Contrary to the common view that laughter is elicited by external stimuli, participants frequently laughed after their own verbal utterances. We thus suggest that laughter in conversation may primarily serve to regulate the flow of interaction and to mitigate the meaning of the preceding utterance. Conversational laughter bouts consisted of a smaller number of laughter elements and had longer interval durations than laughter bouts elicited by media. These parameters also varied with conversational context. The high intraindividual variability in the acoustic parameters of laughter, which greatly exceeded the parameter variability between subjects, may thus be a result of the laughter context.     

Salient Beliefs About Earthquake Hazards and Household Preparedness

Prior research has found little or no direct link between beliefs about earthquake risk and household preparedness. Furthermore, only limited work has been conducted on how people's beliefs influence the nature and number of preparedness measures adopted. To address this gap, 48 qualitative interviews were undertaken with residents in three urban locations in New Zealand subject to seismic risk. The study aimed to identify the diverse hazard and preparedness‐related beliefs people hold and to articulate how these are influenced by public education to encourage preparedness. The study also explored how beliefs and competencies at personal, social, and environmental levels interact to influence people's risk management choices. Three main categories of beliefs were found: hazard beliefs; preparedness beliefs; and personal beliefs. Several salient beliefs found previously to influence the preparedness process were confirmed by this study, including beliefs related to earthquakes being an inevitable and imminent threat, self‐efficacy, outcome expectancy, personal responsibility, responsibility for others, and beliefs related to denial, fatalism, normalization bias, and optimistic bias. New salient beliefs were also identified (e.g., preparedness being a “way of life”), as well as insight into how some of these beliefs interact within the wider informational and societal context.     

No Longer Intending: The Relationship Between Relinquished Fertility Intentions and Distress

We use data from both waves of the National Survey of Families and Households to assess whether relinquishing a serious intention to have (more) children leads to greater increases in depressive symptoms than continuing confidence in childbearing intentions. Our sample includes 2,200 individuals of childbearing age, men and women, all parities, and all marital statuses. Change score analysis shows that individuals who relinquished a serious intent to have children had elevated distress at Time 2 and that the association is conditioned by gender, health, and education. We find that fertility potential can be important to psychosocial well‐being and that closing the door on future fertility, especially for women, those in ill health, and the better educated, leads to increased distress.     

Efficient survey sampling of households via Gaussian quadrature

Summary.  The collection of data through surveys is a costly and time-consuming process, particularly when complex economic data are involved. The paper presents an efficient approach, based on Gaussian quadrature, to survey sampling when some information is available about the target population. Using household data from Mozambique, we demonstrate that Gaussian quadrature subsamples, based on relatively easy to observe household characteristics such as size and educational attainment of members, generate better estimates of the moments of household expenditure than random samples of equal size.     

Do the Benefits Justify the Costs? An Evaluation of the ‘Sitter Service’ in Scotland

This research identified the costs and benefits of the sitter service in Scotland. A ‘sitter service’ is one that provides home‐based childcare outside the hours of 8:00 am to 6:00 pm on weekdays and at weekends to support children of shift workers, single parents/carers and for children who require additional support. Nine sitter services, organised by voluntary or not‐for‐profit organisations in Scotland, were contacted; their costs were compared and the views of sitters and users identified. For very little expenditure, they provided a service that resulted in a range of individual and community benefits. However, the research concludes that most sitter services are hat small scale and piecemeal funding endangers their long‐term viability.     

Turning sexual science into news: sex research and the media.

In this article we report on the findings of a two-part project investigating contemporary issues in sexuality researchers' interaction with journalists. The goal of the project was to explore best practices and suggest curricular and training initiatives for sexuality researchers and journalists that would enhance the accurate dissemination of sexuality research results in the media. We present the results of a survey of a convenience sample of 94 sexuality researchers about their experiences and concerns regarding media coverage and a summary of the main themes that emerged from an invitational conference of sexuality researchers and journalists. In addition, we present some preliminary recommendations for training and best practices. Topics assessed include reporting accuracy; sex researchers' comfort with various topics, media, and journalists; researchers' perceptions of the purpose and content of articles; concern about the impact of media coverage; and training for sexuality researchers.
