The European Basic Safety Standards (EU-BSS) describes a set of NORM (Naturally Occurring Radioactive Material)-processing industries which produce residues known to be possibly enriched in NORs (Naturally Occurring Radionuclides). These residues can be used as a component in building materials aimed for public usage. The industrial processes, in which the residues are produced, are often complex and total monitoring can be challenging especially when the origin of the used raw materials varies. In this study the NORs present in non-ferrous fayalite slags of a secondary smelter facility, a NORM-processing industry according to the EU-BSS, were monitored daily during a one-month production period...

Herjeet Marway
Fair skin is often regarded as a beauty ideal in many parts of the world. Genetic selection for non-disease traits may allow reproducers to select fair skin for the purposes of beauty, and may be justified under various procreative principles. In this paper I assess the ethics of genetic selection for fair skin as a beauty feature. In particular, I explore the discriminatory aspects and demands of such selection. Using race and colour hierarchies that many would find objectionable, I argue that selection for beauty that is underpinned by such hierarchies is not a trivial selection...

BACKGROUND/AIMS: Appropriate and timely screening instruments that sensitively capture the cognitive functioning of multiple sclerosis (MS) patients are the need of the hour. We evaluated newly derived regression-based norms for the Symbol Digit Modalities Test (SDMT) in a Dutch-speaking sample, as an indicator of the cognitive state of MS patients. METHODS: Regression-based norms for the SDMT were created from a healthy control sample (n = 96) and used to convert MS patients' (n = 157) raw scores to demographically adjusted Z-scores, correcting for the effects of age, age2, gender, and education...

BACKGROUND: The objective of the current study was to examine social functioning among adolescents and young adults (AYAs) within the first 2 years after a cancer diagnosis and compare their scores with population norms and identify trajectories of social functioning over time and its correlates. METHODS: A multicenter, longitudinal study was conducted among 215 AYA patients with cancer aged 14 to 39 years. A total of 141 patients completed a self-report measure of social functioning within the first 4 months of diagnosis and again at 12 months and 24 months later...

BACKGROUND: This study aimed to examine potential differences in walking, cycling, public transport and passive transport (car/moped/motorcycle) to work and to other destinations between college and non-college educated working young adults. Secondly, we aimed to investigate which psychosocial and environmental factors are associated with the four transport modes and whether these associations differ between college and non-college educated working young adults. METHODS: In this cross-sectional study, 224 working young adults completed an online questionnaire assessing socio-demographic variables (8 items), psychosocial variables (6 items), environmental variables (10 items) and transport mode (4 types) and duration to work/other destinations...

The relationship between the coral genotype and the environment is an important area of research in degraded coral reef ecosystems. We used a reciprocal outplanting experiment with 930 corals representing ten genotypes on each of eight reefs to investigate the influence of genotype and the environment on growth and survivorship in the threatened Caribbean staghorn coral, Acropora cervicornis. Coral genotype and site were strong drivers of coral growth and individual genotypes exhibited flexible, non-conserved reaction norms, complemented by ten-fold differences in growth between specific G-E combinations...

Advances in virtual reality technology present new opportunities for human factors research in areas that are dangerous, difficult, or expensive to study in the real world. The authors developed a new pedestrian simulator using the HTC Vive head mounted display and Unity software. Pedestrian head position and orientation were tracked as participants attempted to safely cross a virtual signalized intersection (5.5 m). In 10% of 60 trials, a vehicle violated the traffic signal and in 10.84% of these trials, a collision between the vehicle and the pedestrian was observed...

This article tests a longitudinal model of the antecedents and consequences of changes in identification with indigenous (Mapuche) among indigenous and nonindigenous youth in Chilean school contexts over a 6-month period (633 nonindigenous and 270 Mapuche students, Mages  = 12.47 and 12.80 years, respectively). Results revealed that in-group norms supporting contact and quality of intergroup contact at Time 1 predicted student's changes in Mapuche identification at Time 2, which in turn predicted changes in support for adoption of Chilean culture and maintenance of Mapuche culture at Time 2; some of the relationships between these variables were found to be moderated by age and ethnicity...

This study examined differences in women's anticipated emotional orientations towards unintended pregnancy by relationship status and race/ethnicity. Data from a prospective survey of 437 women aged 18-44 who intended no more children for at least two years were analyzed along with 27 in-depth interviews among a diverse sub-sample. Cohabiting women and women in a romantic relationship not living together were less likely to profess happiness (OR=0.42, p<.05, OR=0.25, p<.01, respectively), even when partners' intentions/feelings were controlled...

BACKGROUND: The well-known insertion/deletion polymorphism (rs4646994) of the angiotensin-converting enzyme (ACE) gene has been previously associated with obesity, blood flow, muscular strength, and ACE enzyme activity. Despite the relevant role of ACE in homeostasis, few data are currently available on the relationship between rs4646994 and hydration status. Thus, we tested the association between the ACE Ins/Del polymorphism, body composition, and hydration status in a young Italian population...

We review the latest research investigating how people explain their own actions when they have been activated nonconsciously. We will discuss evidence that when nonconsciously activated behavior is unexpected (e.g., norm- violating, against self -standards), negative affect arises and triggers confabulations aimed to explain the behavior. Nonconsciously activated behaviors may provide a window into everyday confabulation of (erroneous) explanations for behavior, which may also affect self-knowledge. Implications for self-concept formation and intentionality are discussed...

OBJECTIVE: Although there is no causal relationship to medical morbidity, routine clinical assessment of somatic symptoms aids medical diagnosis and assessment of treatment effectiveness. Regardless of their causes, somatic symptoms indicate suffering, distress, and help-seeking behavior. The aim of the present study was to develop and validate a brief self-report questionnaire to assess somatic symptom strain. METHODS: A brief form of the Giessen Subjective Complaints List (GBB-8) was developed and validated in a large population sample representative of the Federal Republic of Germany (N=2008)...

This study examined how the experience of harsh discipline from teachers is related to students' experience of bullying victimization in a Philippine high school. Respondents were 401 first- to fourth-year high school students of an urban public school in the Philippines. Using structural equation modeling, a hypothesized model with direct associations between harsh discipline and bullying victimization, and an indirect path via students' perception of teacher support, was tested. The data adequately fit the model and showed that experiences of harsh teacher discipline predicted higher bullying victimization and students' negative perception of teacher support...

YouTube, a popular online site for user-generated content, is emerging as a powerful source of peer modeling of smoking. Previous research suggests that in counteracting such influence, health messages may inadvertently increase the perceived prevalence of drug use (a descriptive norm) without reducing its acceptability (injunctive norm). This research tested the ability of health messages to reduce the social acceptability of peer smoking on YouTube despite enhancing its perceived prevalence. In an online experiment with 999 adolescents, participants were randomly assigned to view one of two videos: (a) a mosaic displaying a variety of YouTube videos of adolescents smoking followed by a message about the mortality risk to those smokers, or (b) a control video on a health topic unrelated to smoking...

Karen N Breidahl
Since the late 1990s, a wide range of so-called new civic integration policies aimed at civilizing or disciplining newcomers have been introduced. Consequently, migration scholars have discussed whether a converging restrictive 'civic turn' has taken place in Western Europe or whether national models have been resilient: Based on an in-depth historical and comparative analysis of labour market activation policies targeting newly arrived immigrants in Sweden, Norway, and Denmark since the early 1990s, the article contributes to the overall question: To what extent do the institutional pathways of the Scandinavian welfare states prevail when confronted with newcomers? Activation policies targeting newly arrived immigrants exemplifies how the ambition of states to promote functional, individual autonomy is also an important, ongoing process in diverse policy areas of the welfare state and not restricted to early integration instruments...
