The Application of Remote Sensing for Detecting Mass Graves: An Experimental Animal Case Study from Costa Rica*

Abstract: Detection of mass graves utilizing the hyperspectral information in airborne or satellite imagery is an untested application of remote sensing technology. We examined the in situ spectral reflectance of an experimental animal mass grave in a tropical moist forest environment and compared it to an identically constructed false grave which was refilled with soil, but contained no cattle carcasses over the course of a 16‐month period. The separability of the in situ reflectance spectra was examined with a combination of feature selection and five different nonparametric pattern classifiers. We also scaled up the analysis to examine the spectral signature of the same experimental mass grave from an air‐borne hyperspectral image collected 1 month following burial. Our results indicate that at both scales (in situ and airborne), the experimental grave had a spectral signature that was distinct and therefore detectable from the false grave. In addition, we observed that vegetation regeneration was severely inhibited over the mass grave containing cattle carcasses for up to a period of 16 months. This experimental study has demonstrated the real utility of airborne hyperspectral imagery for the detection of a relatively small mass grave (5 m²) within a specific climatic zone. Other climatic zones will require similar actualistic modeling studies, but it is clear that the applications of this technology provide the international community with both an early detection tool and a tool for ongoing monitoring.     

Instruction Bias and Lineup Presentation Moderate the Effects of Administrator Knowledge on Eyewitness Identification

Pairs (N = 234) of witnesses and lineup administrators completed an identification task in which administrator knowledge, lineup presentation, instruction bias, and target presence were manipulated. Administrator knowledge had the greatest effect on identifications of the suspect for simultaneous photospreads paired with biased instructions, with single-blind administrations increasing identifications of the suspect. When biased instructions were given, single-blind administrations produced fewer foil identifications than double-blind administrations. Administrators exhibited a greater proportion of biasing behaviors during single-blind administrations than during double-blind administrations. The diagnosticity of identifications of the suspect in double-blind administrations was double their diagnosticity in single-blind administrations. These results suggest that when biasing factors are present to increase a witness’s propensity to guess, single-blind administrator behavior influences witnesses to identify the suspect.     

Eating Regulation Styles, Appearance Schemas, and Body Satisfaction Predict Changes in Body Fat for Emerging Adults

Obesity and high body fat percentages are a major public health issue. The percentage of obese and overweight Americans has increased over the past 30 years. On average, overweight individuals with higher percent body fat than normal weight individuals are at increased risk for numerous negative outcomes both physically and mentally. A prime time to investigate changes in body composition and associated psychological influences on decision making is during the emerging adulthood period. The first few years of college are a time when adolescents begin to regulate for themselves their own eating behaviors. Previous research shows that freshmen gain weight and increase in percent body fat during their first year of college. The current study addresses the limitations of previous research by investigating (1) individual growth in percent body fat over a longer period of time in college than previous available research and (2) important psychological and sex differences in this growth. This study measures percent body fat across the first 3 years of college at 8 time points for 542 undergraduates (351 females, 65 %; 191 males, 35 %). Longitudinal data analysis was conducted to identify changes in percent body fat, psychological predictors of those changes, and how changes differ for males and females. Our study found that significant increases exist in percent body fat during undergraduates' college years and that change differs for males and females. In addition, through the use of nested hierarchical models, eating regulation style (autonomous or controlled regulation), appearance schema (self-evaluative salience or motivational salience), and body satisfaction were identified as influential predictors of change in percent body fat. For example, young females, who do not feel in control of their physical appearance yet spend a great deal of time maintaining their appearance, have the highest initial body fat percentage and the steepest increase in percent body fat. Overall, males and females with high autonomous regulation and high motivational salience are likely to maintain (instead of increase) percent body fat over the college years. Knowing the influence of these predictors can be useful for promoting health and intervening with young adults in the college setting and other emerging adults who are not enrolled in postsecondary institutions.     

Cultural Orientations,Parental Beliefs and Practices,and Latino Adolescents’ Autonomy and Independence

Despite the salience of behavioral autonomy and independence to parent–child interactions during middle adolescence, little is known about parenting processes pertinent to youth autonomy development for Latino families. Among a diverse sample of 684 Latino-origin parent–adolescent dyads in Houston, Texas, this study examines how parents’ cultural orientations are associated directly and indirectly, through parental beliefs, with parenting practices giving youth behavioral autonomy and independence. Informed by social domain theory, the study’s parenting constructs pertain to youth behaviors in an “ambiguously personal” domain—activities that adolescents believe are up to youth to decide, but which parents might argue require parents’ supervision, knowledge, and/or decision-making. Results for latent profile analyses of parents’ cultural identity across various facets of acculturation indicate considerable cultural heterogeneity among Latino parents. Although 43 % of parents have a Latino cultural orientation, others represent Spanish-speaking/bicultural (21 %), bilingual/bicultural (15 %), English-speaking/bicultural (15 %), or US (6 %) cultural orientations. Structural equation modeling results indicate that bilingual/bicultural, English-speaking/bicultural, and US-oriented parents report less emphasis on the legitimacy of parental authority and younger age expectations for youth to engage in independent behaviors than do Latino-oriented parents. Parental beliefs endorsing youth’s behavioral independence and autonomy, in turn, are associated with less stringent parental rules (parental report), less parental supervision (parental and youth report), and more youth autonomy in decision-making (parental and youth report). Evidence thus supports the idea that the diverse cultural orientations of Latino parents in the US may result in considerable variations in parenting processes pertinent to Latino adolescents’ development.     

Developmental Trajectories of Prejudice and Tolerance Toward Immigrants from Early to Late Adolescence

Adolescence is an important period for the development of relationships between immigrants and non-immigrants, yet little is known about how problematic personality traits affect adolescents’ relationships with and attitudes toward immigrants. This work identified the roles of intergroup relationships and one dimension of problematic personality traits, namely callous–unemotional traits, in the development of adolescents’ tolerance and prejudice. Three annual measurements of a large community sample (N = 1,542) of non-immigrant adolescents (M _age = 15.31 at first measurement; 50.2 % girls) were used to show that tolerance and prejudice toward immigrants represent two dimensions with distinct developmental trajectories from early to late adolescence. Callous–unemotional traits predicted fewer decreases in prejudice toward immigrants, yet were not directly associated with tolerance. Intergroup friendships predicted stronger increases in tolerance, which, in turn, predicted decreases in prejudice toward immigrants. Thus, tolerance and prejudice toward immigrants seem to be differentially influenced by social experiences and problematic personality traits.     

Westminster No More? Governance,Devolution and Delegation in Scotland

Abstract

Politicians have returned frequently to the need to reform schools to achieve wider objectives of social reform and economic prosperity. Within the UK education systems, however, there have been differing experiences and approaches at both national (Scottish, English, Welsh and Northern Irish) and local levels towards school governance reform. School governance in Scotland remains distinct compared to the rest of the UK, both in terms of the pace of reform and the content. The pace of reform in Scotland has been slower and the content has been shaped to a greater extent by political and professional modes of accountability. This article argues that a new phase in school governance reform is likely to follow the election of the Scottish National Party (SNP) majority government in May 2011. A number of factors both external (international comparison of the school performance; the post 2008 politics of austerity) and internal (changes led by the SNP government to the policy-making process, namely outcomes-based policy-making) have placed debates about school autonomy and school governance on the political agenda.

Legitimating beliefs: Sources and indicators

The more a government is effective and fair, the more legitimacy that government is likely to attain, and the more it will possess the potential to elicit compliance without excessive monitoring or punitive action. We explore this proposition using contemporary survey data from sub‐Saharan Africa. In particular, we are interested in the conditions that promote popular legitimating beliefs that provide support for governments that are attempting to serve their entire populations competently and in a manner that is relatively impartial and equitable. This article provides empirical support for a long hypothesized link between the extent of government effectiveness, procedural justice, and citizens' willingness to defer to governmental tax authority. The sample, drawn from a continuum of developing societies in Africa, allows us to analyze the impact of variations in government effectiveness and citizen perceptions of fairness on the sense of obligation to comply with the tax authorities, our indicator for legitimating beliefs.     

Towards a critique of the theory of state monopoly capitalism

Marx and Engels's writings on Ireland are usually associated with their positive support for Irish nationalism. This article seeks to examine the extent and depth of their knowledge of Ireland, politically and economically, by focusing attention on Marx's analysis of post-famine agricultural readjustment. Comparing the latter's comments in Capitaland elsewhere with actual developments, it is suggested that Marx and Engels's understanding was less than accurate. The source of their misinterpretation lies principally with their inadequate analysis of tenants, agrarian capitalism, and land fever.
