Computer services and the development of rural areas: Trends in the Pacific Northwest in the 1990s

Some researchers hypothesize that the increasing use of computers and telecommunications will lead to a greater flexibility in the location of jobs, particularly in nonmetro counties. Others see the continued dominance of metro counties, especially in well-paid employment. This research examines change in employment in the service category of computer and data processing comparing this with the broader categories of business and producer services. Trends in metro and nonmetro counties of the Pacific Northwest in the 1990s are evaluated to see if inequality between county types in these industry categories widened or narrowed over time. Findings from this research indicate that while nonmetro counties did increase their share of overall employment, employment in producer, business and, notably, computer services remained highly concentrated in metro counties. Location quotients also show that computer service employment was increasingly over-represented in dominant metro economies. In addition, the inequality in estimated salaries between the two largest metro counties in the region and other county types increased substantially in the short time period under consideration.     

Posterior likelihood ratios for evaluation of forensic trace evidence given a two-level model on the data

In forensic science, in order to determine whether sets of traces are from the same source or not, it is widely advocated to evaluate evidential value of similarity of the traces by likelihood ratios (LRs). If traces are expressed by measurements following a two-level model with random effects and known variances, closed LR formulas are available given normality, or kernel density distributions, on the effects. For the known variances estimators are used though, which leads to uncertainty on the resulting LRs which is hard to quantify. The above is analyzed in an approach in which both effects and variances are random, following standard prior distributions on univariate data, leading to posterior LRs. For non-informative and conjugate priors, closed LR formulas are obtained that are interesting in structure and generalize a known result given fixed variance. A semi-conjugate prior on the model seems usable in many applications. It is described how to obtain credible intervals using Monte Carlo Markov Chain and regular simulation, and an example is described for comparison of XTC tablets based on MDMA content. In this way, uncertainty on LR estimation is expressed more clearly which makes the evidential value more transparent in a judicial context.     

Approximations to permutation distributions in the completely randomized design

The permutation distribution of a statistic T equivalent to the usual F ratio for the completely randomized design is considered. A correction to the second moment of T derived by Robinson (1983) is presented and the third and fourth moments are educed. Inadequacies in the conventional permutation distribution approximations are demonstrated.     

Visualising everyday ethnicity: moving beyond stereotypes of Roma minorities

ABSTRACT

The visual image of Roma people in the media is mired in racialised notions of ‘the other’. Whilst we know what Roma stereotypes look like, there is little clarity as to how a ‘non-stereotypical’ image might be constructed. In order to examine the non-stereotypical, two sources of images are analysed: (1) entrants from an anti-stereotype Roma photography competition and (2) self-representations produced by Roma participants during ethnographic research. The findings show that if ‘Roma’ is foregrounded as the subject, even a non-stereotypical approach can reproduce ‘difference’ (from a supposed ‘norm’). ‘Roma’ is thus, at the moment, still strongly linked to a notion of ethnicity that is seen as different and racialised. However, when ethnicity is not emphasised, but rather self-representations and the ‘everyday’, such orthodoxies are challenged. These sources provide a unique opportunity to create a deeper understanding of ‘non-stereotypical’ images in order to challenge misrepresentations and racism.     

DETERMINANTS OF REVENUE IN SPORTS LEAGUES: AN EMPIRICAL ASSESSMENT

This study investigates determinants of revenue in North America's four major professional sports leagues. Revenue is positively associated with on‐field success in baseball (MLB), basketball (NBA), and hockey (NHL), but not in football (NFL). The returns to success are not diminishing as commonly assumed, which casts doubt on the uncertainty of outcome hypothesis, and differences across leagues are consistent with revenue sharing arrangements. Estimates indicate a strong negative but diminishing relationship between stadium age and revenue. Teams in larger markets generate more revenue than smaller markets, but the returns to success do not differ according to market size. (JEL Z21)     

Understanding Settlement Pathways of African Immigrants in France Through a Capability Approach: Do Pre-migratory Characteristics Matter?

With the increase in asylum-related immigration since 2015, understanding how immigrants settle in a new country is at the centre of social and political debate in European countries. The objective of this study is to determine whether the necessary time to settle for Sub-Saharan Africa immigrants in France depends more on pre-migratory characteristics or on the structural features of the host society. Taking a capability approach, we define settlement as the acquisition of three basic resources: a personal dwelling, a legal permit of a least 1 year and paid work. We use data from the PARCOURS survey, a life-event history survey conducted from 2012 to 2013 that collected 513 life histories of Sub-Saharan African immigrants living in France. Situations regarding housing, legal status and activity were documented year by year since the arrival of the respondent. We use a Kaplan–Meier analysis and chronograms to describe the time needed for settlement, first for each resource (personal dwelling, legal permit and paid work) and then for the combined indicator of settlement. Discrete-time logistic regressions are used to model the determinants of this settlement process. Overall, women and men require 6 and 7 years (medians), respectively, to acquire basic resources in France. This represents a strikingly long period of time in which immigrants lack basic security. The settlement process varies according to gender, but very few sociodemographic factors influence settlement dynamics. Therefore, the length of the settlement process may be due to structural features of the host society.     

Children's accounts of moving to a foster home

Little is known about how children themselves understand their moves to and between foster homes. The data presented in this paper come from a study that sought children's views on becoming and being a foster child. A key finding of that study was how children's accounts of being fostered illustrated a high level of anxiety and concern about their moving to live with a foster family. This paper firstly explores the key issues about looked‐after children's moves. It then describes the research study undertaken, before exploring the data generated from children's accounts of their moves to a new foster home. Lastly, there is a discussion of the implications for social work practice in this area.
