A nonparametric statistical procedure for the detection of marine pollution

This paper is devoted to the estimation of the derivative of the regression function in fixed-design nonparametric regression. We establish the almost sure convergence as well as the asymptotic normality of our estimate. We also provide concentration inequalities which are useful for small sample sizes. Numerical experiments on simulated data show that our nonparametric statistical procedure performs very well. We also illustrate our approach on high-frequency environmental data for the study of marine pollution.     

An action research methodology for manufacturing technology selection: a supply chain perspective

This paper presents an empirical research approach to developing and implementing a manufacturing technology-selection framework. In this paper, the selection of action research as an empirical research methodology is preferred because it provides the researcher with the necessary flexibility to actively participate in the research activity and to analyse the situation in detail by being part of the research system under investigation. The main objective of this paper is to use action research as an empirical research tool in order to provide a methodology for technology selection in the context of extended supply chains considering intra- and inter-organisational (supply chain) perspective while promoting active collaboration between industry and academia.     

Physiological Daily Inhalation Rates for Health Risk Assessment in Overweight/Obese Children,Adults, and Elderly

Physiological daily inhalation rates reported in our previous study for normal‐weight subjects 2.6–96 years old were compared to inhalation data determined in free‐living overweight/obese individuals (n = 661) aged 5–96 years. Inhalation rates were also calculated in normal‐weight (n = 408), overweight (n = 225), and obese classes 1, 2, and 3 adults (n = 134) aged 20–96 years. These inhalation values were based on published indirect calorimetry measurements (n = 1,069) and disappearance rates of oral doses of water isotopes (i.e., ²H₂O and H₂¹⁸O) monitored by gas isotope ratio mass spectrometry usually in urine samples for an aggregate period of over 16,000 days. Ventilatory equivalents for overweight/obese subjects at rest and during their aggregate daytime activities (28.99 ± 6.03 L to 34.82 ± 8.22 L of air inhaled/L of oxygen consumed; mean ±  SD) were determined and used for calculations of inhalation rates. The interindividual variability factor calculated as the ratio of the highest 99th percentile to the lowest 1st percentile of daily inhalation rates is higher for absolute data expressed in m³/day (26.7) compared to those of data in m³/kg‐day (12.2) and m³/m²‐day (5.9). Higher absolute rates generally found in overweight/obese individuals compared to their normal‐weight counterparts suggest higher intakes of air pollutants (in μg/day) for the former compared to the latter during identical exposure concentrations and conditions. Highest absolute mean (24.57 m³/day) and 99th percentile (55.55 m³/day) values were found in obese class 2 adults. They inhale on average 8.21 m³ more air per day than normal‐weight adults.     

Christ vs. Communism: Communism as a Religious Social Problem in Finland's Proto‐Fascist Lapua Movement in the 1930s

This article traces the emergence of religious anti‐communist discourse in Finland's proto‐fascist Lapua Movement in the 1930s. Applying constructionist social problems theory, it discusses the constructions of communism as a religious social problem, Christian piety as a solution to the problem of godless communism, and the religious legitimation of violence. The article argues that by identifying Christianity with the Finnish nation the construction of communism as a religious problem—itself an outcome of the influence of revivalist Lutheran ministers in the leadership of the movement—resonated with the broader audience, but that this indigenous religious nationalism lost support with the increasing belligerence of the movement.     

Alternative Tests for Parameter Stability

ABSTRACT

We propose new tests for parameter stability based on estimates computed from a sequence of subsamples moving forward and backward across the sample. We obtain a sequence of moving estimates tests and we derive their asymptotic null distribution based on the functional central limit theorem. The critical values are approximated using Durbin's method. Our simulation results show that these tests have comparable size and slightly higher power in detecting structural change than other competing tests.     

Business ethics,company value and ownership structure

This paper examines the effect of ethical performance on the value of a company and the attractiveness of its stocks for major owners; institutional investors and insiders. Using the Ethisphere^® Institute Ethics Quotient to distinguish between ethical and unethical companies, results show that good ethical performance enhanced company value for a sample of 240 large US companies. Furthermore, strong evidence is found that institutional investors are attracted to ethical companies, but that insiders do not show any investment preferences based on the ethical performance of a company.

     

Achievement Orientations,School Adjustment,and Well-being: A Longitudinal Study

This study set out to identify the kinds of achievement orientations that adolescents show, and to examine the kinds of antecedents and consequences the use of a particular orientation has. The participants were 734 Swedish adolescents (335 boys and 399 girls) who filled in questionnaires measuring their achievement beliefs and behaviors, depressive symptoms, engagement with school, and norm-breaking behavior. By using clustering-by-cases analysis, five achievement orientation groups were identified: optimism, defensive-pessimism, self-handicapping, and learned helplessness, and a group showing average levels of criteria variables. The results showed further that a decrease in depressive symptoms and an increase in engagement with school predicted a move to the use of optimistic and defensive-pessimistic groups, whereas a reverse pattern predicted a move to the helplessness and self-handicapping groups. Moreover, the optimistic and defensive-pessimistic achievement orientations at Time 1 predicted an increase in engagement with school and a decrease in depressive symptoms later on, whereas self-handicapping and learned helplessness predicted a decrease in engagement with school and increases in depressive symptoms and norm-breaking behavior.     

Breaking the in‐group out‐group: shifting boundaries in transnational partner choice processes of individuals of Moroccan,Tunisian, Algerian,Turkish, Punjabi Sikh,Pakistani and Albanian descent in Belgium

The ongoing popularity in some second and third generation migrants in Western Europe of marrying a partner from the countries of origin of their (grand)parents is considered to be problematic for micro and macro level societal integration of some migrant populations. Partner choice and marriage practices in migrant communities are problematized in public, media and political discourses by discriminating them from marriage practices in the ‘native’ population on the basis of three related dichotomies: (1) agency versus structure, (2) us versus them and (3) romantic versus instrumental marriage intentions dichotomies. By means of in‐depth qualitative research methodologies on the partner choice processes of women and men of Turkish, Moroccan, Algerian, Tunisian, Punjabi Sikh, Pakistani and Albanian descent in Belgium and an intersectional theoretical approach, this article aims to deconstruct popular and simplifying dichotomous representations of partner choice processes in these migrant populations. Our study reveals how religious, gender and social class boundaries are stretched to meet personal/individual desires and preferences. Individuals do experience social restrictions when it concerns social group boundaries and the potential partners that they can look for. At the same time individuals are never fully determined by their social environment, they creatively develop strategies to by‐pass certain restrictions and to some extent are able to meet their personal needs while being sensitive to the desires of their social environment.     

The Relationship Among the Material Welfare,Maternity, and Marital Status of Women in the State of Georgia

Childbearing among unmarried women has been the subject of intense public health debate for decades, reflecting concerns about the impact on family structure and the economic security of born children. This report analyzes 2007 data from the OASIS, the website of the Division of Public Health of the Georgia Department of Community Health. Significant inverse correlations were recorded among the counties' median household income on one side and birth rate (r = –.239, p < .01), percentage of all births from unmarried mothers (r = –.679, p < .001), and percentage of all births from mothers with less than a 12th-grade education (r = –.488, p < .001). We believe that creating a network of maternity education and support programs across the state of Georgia that works under centralized supervision from a maternity committee could help alleviate the negative effect of median household income on nonmarital birth and decrease regional disparities related to nonmarital births.     

The Early‐career Gender Wage Gap among University Graduates in the Finnish Private Sector

In the Finnish private sector, the gender wage gap increases significantly during the first 10 years after labour market entry, accounting for most of the lifetime increase in the gender wage differentials. This paper investigates the reasons for this gender difference in early‐career wage development. By focusing on university graduates the paper considers several explanations based on the human capital theory, job mobility, and labour market segregation. The results suggest that only about 20–26 per cent of the average early‐career gender wage gap is explained by gender differences in experience, the field of education, employer characteristics, and mobility. A substantial unexplained gap thus remains. Of the investigated factors gender differences in the field of education and work experience matter most.
