Party on wheels: mobile party spaces in the Norwegian high school graduation celebration

Research on partying and nightlife often emphasizes commercial control while overlooking participants’ creativity and agency. Due to their age, appearance and transgressive partying, participants in the Norwegian high school graduation celebration have limited access to bars and pubs in the ordinary night‐time economy. To create alternative party spaces under their own control they utilize the spatial opportunities offered by automobility. Groups of students get together many years in advance and buy old buses which they refurbish to become rolling nightclubs that enable them to ‘transcend space’ through partying while on the move. These mobile party spaces provide a material and symbolic centre of communion and a tight space for physical assembly that enhances the production of intense positive emotions. In a cat‐and‐mouse game with the police, the buses provide a sense of nomadic autonomy, and enable participants to drink heavily for days on end. The study examines how youth may creatively zone their own party spaces within the context of automobility and how these mobile spaces again shape the partying that goes on within them. While this party practice opens up for autonomy, creativity and social transgressions reminiscent of liminal phases or carnivals, at a deeper level participants clearly reproduce class‐based differences and exaggerate conventional practices and symbols.     

SEPARATION, WEAK EXOGENEITY, AND P-T DECOMPOSITION IN COINTEGRATED VAR SYSTEMS WITH COMMON FEATURES

The aim of this paper is to study the concept of separability in multiple nonstationary time series displaying both common stochastic trends and common stochastic cycles. When modeling the dynamics of multiple time series for a panel of several entities such as countries, sectors, firms, imposing some form of separability and commonalities is often required to restrict the dimension of the parameter space. For this purpose we introduce the concept of common feature separation and investigate the relationships between separation in cointegration and separation in serial correlation common features. Loosely speaking we investigate whether a set of time series can be partitioned into subsets such that there are serial correlation common features within the sub-groups only. The paper investigates three issues. First, it provides conditions for separating joint cointegrating vectors into marginal cointegrating vectors as well as separating joint short-term dynamics into marginal short-term dynamics. Second, conditions for making permanent-transitory decompositions based on marginal systems are given. Third, issues of weak exogeneity are considered. Likelihood ratio type tests for the different hypotheses under study are proposed. An empirical analysis of the link between economic fluctuations in the United States and Canada shows the practical relevance of the approach proposed in this paper.     

Macroeconomic Forecasting Using Pooled International Data

The genetic algorithm is examined as a method for solving optimization problems in econometric estimation. It does not restrict either the form or regularity of the objective function, allows a reasonably large parameter space, and does not rely on a point-to-point search. The performance is evaluated through two sets of experiments on standard test problems as well as econometric problems from the literature. First, alternative genetic algorithms that vary over mutation and crossover rates, population sizes, and other features are contrasted. Second, the genetic algorithm is compared to Nelder–Mead simplex, simulated annealing, adaptive random search, and MSCORE.     

Computing Wald criteria for nested hypotheses

We present a numerically convenient procedure for computing Wald criteria for nested hypotheses. Similar to Szroeter’s (1983) generalized Wald test, the suggested procedure does not require explicit derivation of the restrictions implied by the null hypothesis and hence its use might eliminate an intricate step in testing linear and nonlinear hypotheses. We show that the traditional Wald test, Szroeter’s (1983) generalized Wald test and our procedure are asymptotically equivalent under H₀. A class of nonlinear transformations of the restrictions for which the Wald statistic is asymptotically invariant is discussed. Finally, we illustrate the use of our procedure for testing the common factor restrictions in a dynamic regression model.     

Stress,health and the working environment of Swedish prison staff

Abstract

A random stratified sample of just over 2000 was drawn from staff working in 67 different prisons in Sweden. Questionnaires on working conditions and symptoms of ill health were administered and subjects were given health examinations. Morning plasma Cortisol and gamma glutamyltransferase (g GT) levels were measured and factual information on the prisons was collected for use in the analyses.

There were differences between prisons in terms of both objective and self-reported working conditions which appeared to affect health status, physiological state and sick leave rate. Cardiovascular and hypertensive conditions were found more often among prison staff than among a large reference group made up of many different occupations. Sick leave rates among prison staff, especially those over 45 years old, were very high compared with this reference group. The situation appeared particularly difficult in prisons with a high proportion of drug abusing inmates.

The data allowed the identification of several factors which might counteract the effects of stress at work: a proactive management style, goal consensus among staff, a high degree of decision latitude, satisfaction with work performance and a supportive psychosocial climate.     

Robust Resource Allocation Decisions in Resource‐Constrained Projects*

The well‐known deterministic resource‐constrained project scheduling problem involves the determination of a predictive schedule (baseline schedule or pre‐schedule) of the project activities that satisfies the finish–start precedence relations and the renewable resource constraints under the objective of minimizing the project duration. This baseline schedule serves as a baseline for the execution of the project. During execution, however, the project can be subject to several types of disruptions that may disturb the baseline schedule. Management must then rely on a reactive scheduling procedure for revising or reoptimizing the baseline schedule. The objective of our research is to develop procedures for allocating resources to the activities of a given baseline schedule in order to maximize its stability in the presence of activity duration variability. We propose three integer programming–based heuristics and one constructive procedure for resource allocation. We derive lower bounds for schedule stability and report on computational results obtained on a set of benchmark problems.     

Young Dutch People's Experiences of Trading Sex: A Qualitative Study

In recent years, the subject of transactional sex among young Dutch people has generated a heated social debate in the Netherlands. However, accurate data on this phenomenon are scarce. This article describes the findings of a qualitative study on young Dutch people's experiences of having sex in return for money or a material reward. Thirty in-depth interviews were conducted with young Dutch men and women aged 14 to 24. Participants came from diverse backgrounds in terms of gender, ethnicity, sexual orientation, and socioeconomic status. Experiences of trading sex differed in terms of the motivation to trade sex, the presence or absence of coercion, and the availability of other options for earning money. Participants' feelings about their experiences varied. For most participants, the sex itself was unpleasant and required considerable emotion management. Still, some felt adequately compensated by the reward or felt trading sex was preferable to other jobs. Gender played an important role, with feelings of disgust or shame reported especially by female participants, whereas male participants reported more positive experiences. Interactions involving coercion or financial dependence on trading sex generally had a negative emotional impact. Participants stressed the differences between their own experiences and professional prostitution.     

Sexual Victimization and Physical Health: An Examination of Explanatory Mechanisms

ABSTRACT

There is a growing body of research illustrating a significant relationship between a history of sexual victimization and the development of physical health problems; however, few researchers have examined variables that mediate this relationship. The present study examined two potential mediating variables: experiential avoidance and current stress. Results indicated that current stress significantly mediated the relationship between adult sexual assault and physical health complaints, and experiential avoidance may be a partial mediator. Implications of the findings and future directions are discussed.     

The discreet charm of the children of the bourgeoisie: economic capital and its symbolic expressions at an elite business school

We address a largely neglected issue in contemporary research on cultural class divisions: economic capital and its associated lifestyles and symbolic expressions. Using qualitative interviews, we explore how adolescents from wealthy elite backgrounds, namely students at Oslo Commerce School (OCS), traditionally one of the most prestigious upper‐secondary schools in Norway, demarcate themselves symbolically from others. They draw symbolic boundaries against students at other elite schools in Oslo, more characterized by backgrounds with high cultural capital, accusing them of mimicking a ‘hipster’ style. Within the OCS student body, we describe identity work centring on styles of material consumption and bodily distinctions. The most salient dividing line is between those who manage to master a ‘natural’ style, where expensive clothes and the desired bodily attributes are displayed discreetly, and those who are ‘trying too hard’ and thus marked by the stigma of effort. We also show some interesting intersections between class and gender: girls aspiring to the economic elite obey the ‘rules of the game’ by exercising extensive control over their bodies and adhering to demanding bodily norms for their weight and slimness. Such rules are less evident among the boys, where a lack of discipline, unruliness, hard partying and even fighting constitute parts of the lifestyle valued. This article contributes to the field of cultural stratification, highlighting the importance of the ‘hows’ of material consumption when expressing elite distinction. It also adds new insight to the research field of elite education by showing how a mastery of ‘high‐end’ consumer culture is involved in fostering favourable dispositions at elite schools.
