Population statistics and population registration in Norway. Part 1. The vital statistics of Norway: An historical review

From olden times in Norway, as also in Sweden and Denmark, the church official in each parish has kept the official registers of marriages, births and deaths, and has produced the records which form the basis of Norwegian vital statistics.     

Women's experiences of participation in a pregnancy and postnatal group incorporating yoga and facilitated group discussion: A qualitative evaluation

BackgroundThis paper reports on a small qualitative research study which explored women's experiences of participation in a pregnancy and postnatal group that incorporated yoga and facilitated discussion. The group is offered through a community based feminist non-government women's health Centre in Northern NSW Australia.QuestionThe purpose of the research was to explore women's experiences of attending this pregnancy and postnatal group.MethodsAn exploratory qualitative approach was used to explore women's experiences of attending the group. Fifteen women participated in individual, in-depth face-to-face interviews. Interviews were recorded and transcribed verbatim. Thematic analysis was undertaken to analyse the qualitative data.FindingsSix themes were developed, one with 3 subthemes. One theme was labelled as: ‘the pregnancy and motherhood journey’ and included 3 sub-themes which were labelled: ‘preparation for birth’, ‘connecting with the baby’ and ‘sharing birth stories.’ The other five themes were: ‘feminine nurturing safe space’, ‘watching and learning the mothering’, ‘building mental health, well-being and connections’, the “group like a rock and a seed’ and ‘different from mainstream’.ConclusionThis research adds to the overall body of knowledge about the value of yoga in pre and postnatal care. It demonstrates the value of sharing birth stories and the strong capacity women have to support one another, bringing benefits of emotional and social well-being, information, resources and support derived from group based models of care.     

Sex in America online: an exploration of sex, marital status, and sexual identity in internet sex seeking and its impacts

This was an exploratory study of sex and relationship seeking on the Internet, based on a survey of 15,246 respondents in the United States Seventy-five percent of men and 41% of women had intentionally viewed or downloaded porn. Men and gays/lesbians were more likely to access porn or engage in other sex-seeking behaviors online compared with straights or women. A symmetrical relationship was revealed between men and women as a result of viewing pornography, with women reporting more negative consequences, including lowered body image, partner critical of their body, increased pressure to perform acts seen in pornographic films, and less actual sex, while men reported being more critical of their partners' body and less interested in actual sex. Married and divorced were more likely than singles to go online seeking a serious relationship. Only 2% of users met the threshold of compulsive use established by previous studies.     

French People’s Positions Regarding National Policies About Illicit Drugs: A Preliminary Study

French people’s positions regarding actual and potential drug policies were examined. Adults (N = 225) aged 18–81 were presented with 28 vignettes that were composed according to a three within-subject orthogonal factor design: (a) demand for drugs in the country, (b) information campaigns regarding their dangerousness, and (c) current state policy regarding soft and hard drugs, from “laissez faire” policy for all drugs to complete prohibition of all drugs. Participants rated the level of acceptability of each policy. Three clusters were identified. The first one (32 % of participants) was called “Radical Constructionists” because participants considered that all policies were unacceptable. The second one (26 %) was called “Prohibitionists” because only one drug policy was considered fully acceptable: Complete prohibition with the condition that information campaigns are conducted. The third cluster (42 %) was called “Regulationists” because only one drug policy was considered as fully acceptable: Complete state regulation (with the same condition). In all clusters, the “laissez-faire” policy was always judged as the least acceptable one, even when it was just about soft drugs. The strongest opposition observed was not between prohibition and regulation but between “laissez-faire” on the one hand and regulation and prohibition on the other hand. Methodological implications and implications for decision-makers are discussed.     

Flexible‐Duration Extended Warranties with Dynamic Reliability Learning

Frequent technological innovations and price declines adversely affect sales of extended warranties (EWs) as product replacement upon failure becomes an increasingly attractive alternative. To increase sales and profitability, we propose offering flexible‐duration EWs. These warranties can appeal to customers who are uncertain about how long they will keep the product as well as to customers who are uncertain about the product's reliability. Flexibility may be added to existing services in the form of monthly billing with month‐by‐month commitments or by making existing warranties easier to cancel with pro‐rated refunds. This paper studies flexible warranties from perspectives of both customers and the provider under customers' reliability learning. We present a model of customers' optimal coverage decisions and show that customers' optimal coverage policy has a threshold structure under some mild conditions. We further show that flexible warranties can result in higher profits and higher attach rates in a homogeneous market as well as in a heterogeneous market with multiple segments differing in various dimensions.     

Preference reversals and the measurement of environmental values

Numerous studies have demonstrated that theoretically equivalent measures of preference, such as choices and prices, can lead to systematically different preference orderings, known as preference reversals. Two major causes of preference reversals are the compatibility effect and the prominence effect. The present studies demonstrate that the combined effects of prominence and compatibility lead to predictable preference reversals in settings where improvements in air quality are compared with improvements in consumer commodities by two methods-willingness to pay for each improvement and choice (For which of the two improvements would you pay more? Which improvement is more valuable to you?). Willingness to pay leads to relatively greater preference for improved commodities; choice leads to relatively greater preference for improved air quality. These results extend the domain of preference reversals and pose a challenge to traditional theories of preference. At the applied level, these findings indicate the need to develop new methods for valuing environmental resources.     

D‐optimal minimax fractional factorial designs

The D‐optimal minimax criterion is proposed to construct fractional factorial designs. The resulting designs are very efficient, and robust against misspecification of the effects in the linear model. The criterion was first proposed by Wilmut & Zhou (2011); their work is limited to two‐level factorial designs, however. In this paper we extend this criterion to designs with factors having any levels (including mixed levels) and explore several important properties of this criterion. Theoretical results are obtained for construction of fractional factorial designs in general. This minimax criterion is not only scale invariant, but also invariant under level permutations. Moreover, it can be applied to any run size. This is an advantage over some other existing criteria. The Canadian Journal of Statistics 41: 325–340; 2013 © 2013 Statistical Society of Canada     

Formative evaluation of a motivational intervention for increasing physical activity in underserved youth

The present study was designed to develop an innovative motivational intervention (based on Self-Determination Theory and Social Cognitive Theory) to increase physical activity (PA) in underserved adolescents. Sixty-four adolescents (35 females, 29 males; 50% minority; 65% on reduced lunch program; ages 11-13 yr) participated in either an 8-week motivational intervention after-school (n = 32) or a typical after-school program (n = 32). The conceptual framework for the intervention targeted the social environment (perceived autonomy, perceived social support, participation, fun), cognitive mediators (perceived choice, self-efficacy, and relatedness/belongingness), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Formative evaluation data was collected by staff through daily forms throughout the 8-week program and through observational data completed by independent objective observers during 2 weeks of the program. The major themes that were identified addressed theoretical concepts regarding the intervention and logistical issues in delivering the intervention. The data revealed information regarding the importance of the cognitive appropriateness of the PA and motivational activities, the environmental climate for promoting nurturing relationships, developing specific strategies for increasing intrinsic rather than extrinsic reinforcement, and developing methods for preventing social "cliques" and gender conflicts to maintain an appropriate level of support in the social climate. Themes for training staff included focusing on team building, leadership, and nurturing. This formative evaluation is being used to formalize a randomized trial to test the effects of a student-centered motivational intervention on increasing PA in underserved 6th graders.
