Perceived Skin Tone Discrimination Across Contexts: African American Women’s Reports

There is a void in empirical research that examines African American women’s self-reported skin tone discrimination from out-groups (e.g., whites) and in-groups (blacks). We analyzed data of women from diverse socioeconomic backgrounds in the nationally representative National Survey of American Life (N = 1653). Light-skinned women reported less out-group colorism, and light-, medium-, and dark-skinned women with higher self-mastery perceived lower out-group colorism. Medium-skinned women perceived less in-group colorism, while dark-skinned women perceived more in-group and out-group colorism than counterparts. Implications for intergroup and intragroup race relations as well as well-being are discussed.     

Police Endorse Color-Blind Racial Beliefs More Than Laypersons

Racial disparities in the US criminal justice system (CJS) have been extensively documented in scholarly work. Critical race scholars have suggested that color-blind racial attitudes inform the set of beliefs that CJS practitioners use in decision making. If this is the case, factors that are related to color-blind racial attitude trends in CJS practitioners must be better understood. We focus on a single CJS practitioner—the police—to assess their color-blind racial beliefs and compare these to the broader US public. Using the Color-Blind Racial Attitudes Scale (CoBRAS), we identified sociodemographic variables associated with high CoBRAS scores in a multiracial lay sample (N = 1401; males and females, mean age = 33.4 years). Police (N = 112) and police recruits (N = 52) CoBRAS scores were compared to CoBRAS scores of lay participants with similar sociodemographics as the police and recruit samples, (respectively, N = 451; N = 291). Police scored significantly higher on the CoBRAS than laypersons even when controlling for sociodemographic variables. Police recruits also have higher CoBRAS scores than laypersons, again controlling for sociodemographic variables. These findings suggest that police work attracts people who endorse color-blind racial beliefs. These findings make understanding the relationship between color-blind racial beliefs and discriminatory behavior of CJS practitioners imperative.     

Effects of Affective and Anxiety Disorders on Outcome in Problem Gamblers Attending Routine Cognitive–Behavioural Treatment in South Australia

This study evaluated the influence of 12-month affective and anxiety disorders on treatment outcomes for adult problem gamblers in routine cognitive–behavioural therapy. A cohort study at a state-wide gambling therapy service in South Australia. Primary outcome measure was rated by participants using victorian gambling screen (VGS) ‘harm to self’ sub-scale with validated cut score 21+ (score range 0–60) indicative of problem gambling behaviour. Secondary outcome measure was Work and Social Adjustment Scale (WSAS). Independent variable was severity of affective and anxiety disorders based on Kessler 10 scale. We used propensity score adjusted random-effects models to estimate treatment outcomes for sub-populations of individuals from baseline to 12 month follow-up. Between July, 2010 and December, 2012, 380 participants were eligible for inclusion in the final analysis. Mean age was 44.1 (SD = 13.6) years and 211 (56 %) were males. At baseline, 353 (92.9 %) were diagnosed with a gambling disorder using VGS. For exposure, 175 (46 %) had a very high probability of a 12-month affective or anxiety disorder, 103 (27 %) in the high range and 102 (27 %) in the low to moderate range. For the main analysis, individuals experienced similar clinically significant reductions (improvement) in gambling related outcomes across time (p < 0.001). Individuals with co-varying patterns of problem gambling and 12 month affective and anxiety disorders who present to a gambling help service for treatment in metropolitan South Australia gain similar significant reductions in gambling behaviours from routine cognitive–behavioural therapy in the mid-term.     

Growing Up Where ‘No One Looked Like Me’: Gender,Race, Hip Hop and Identity in Vancouver

This paper examines how youth whose parents came from sub-Saharan Africa negotiate racialized forms of masculinity and femininity in Vancouver, Canada. The study is based on interviews with second generation African-Canadian men and women, and explores gendered and racialized dimensions of growing up in neighbourhoods where they were usually the only African and Black children. In this context, the second generation engages with representations of Black masculinity and femininity widely circulated through American popular culture, especially through hip hop, constituting a dominant frame of reference among adolescents that contributes to the great popularity of African-Canadian teenage boys, while girls find it much harder to fit in.

The population dynamics of the voleClethrionomys rufocanus in Hokkaido, Japan

Population dynamics of the gray sided-vole,Clethrionomys rufocanus, in Hokkaido, Japan were described on the basis of 225 time series (being from 12 to 31 years long); 194 of the time series have a length of 23 years or longer. The time series were classified into 11 groups according to geographic proximity and topographic characteristics of the island of Hokkaido. Mean abundance varied among populations from 1.07 to 21.07 individuals per 150 trap-nights. The index of variability for population fluctuation (s-index) ranged from 0.204 to 0.629. Another index for population variability (amplitude on log-10 scale) ranged from 0.811 to 2.743. Mean abundance and variability of populations were higher in the more northern and eastern regions of the island. Most populations, except for the southernmost populations, exhibited significant direct density-dependence in population growth. Detection rate for delayed density-dependence varied among groups from 0% to 22.6%. Both direct and delayed density-dependence tended to be stronger in the more northern and eastern populations. The proportion of cyclic populations was higher in the northern-eastern areas than that in the southern-western areas. There was a clear gradient from the asynchronous populations in southwest, to the highly synchronized populations in the northeast.

Nonparametric models and their estimation

Summary Nonparametric models have become more and more popular over the last two decades. One reason for their popularity is software availability, which easily allows to fit smooth but otherwise unspecified functions to data. A benefit of the models is that the functional shape of a regression function is not prespecified in advance, but determined by the data. Clearly this allows for more insight which can be interpreted on a substance matter level. This paper gives an overview of available fitting routines, commonly called smoothing procedures. Moreover, a number of extensions to classical scatterplot smoothing are discussed, with examples supporting the advantages of the routines.
