How Can Low‐income Countries Gain from a Framework Agreement on Climate Change? An Analysis with Integrated Assessment Modelling

By using the integrated assessment model RICE this article carries out a scenario analysis with different assumptions about international negotiations on climate change, in particular hypothesising about reduction in targets for greenhouse gas emissions, technology transfers and financial transfer programmes. It finds that, in terms of growth, developing countries and in particular sub‐Saharan Africa will benefit from agreements that reduce the level of pollution and promote technological diffusion. Moreover, when developed countries are subject to emissions limits and poor regions have no such commitments, financial transfers from rich to developing countries for adaptation and mitigation enhance pro‐poor growth and help the effectiveness of poor countries in reducing emissions.     

Why Are Socially Anxious Adolescents Rejected by Peers? The Role of Subject‐Group Similarity Characteristics

This study addressed the role of actual and perceived similarity in peer rejection of socially anxious adolescents. Videotapes of 20 high and 20 low socially anxious adolescents (13–17 years old) giving a speech were rated by groups of unfamiliar peers with regard to perceived similarity and desire for future interaction (lower scores indicating rejection). Actual similarity between speakers and observers regarding social anxiety and gender was also taken into account. Findings showed that high socially anxious students were more rejected and that perceived but not actual similarity between peer observers and speakers (partly) mediated rejection.     

Your lying,incompetent and selfish member of Congress: Cynical appeals in U.S. Senate advertising

Scholars still do not fully understand what activates cynicism in citizens. Although many expect that negative campaigning contributes to this, no consistent evidence has been found. This research introduces a new measure of appeals to cynicism that expands the commonly used positive–negative taxonomy of tone in advertising. Through a content analyses of more than 600 political advertisements aired during U.S. Senate elections, we identify the extent to which candidates use cynical appeals and the conditions under which these are used. We find that appeals to cynicism are common, are distinct from negative appeals, and that most often, ad sponsors target opponents with cynical appeals, describing them as selfish, dishonest and incompetent. Cynicism appears to be a central part of American campaign rhetoric, used by all sorts of candidates, regardless of party, in many different situations. The prevalence of appeals to cynicism may help explain rising cynicism among the public.     

Parental Influence on Friendships Between Native and Immigrant Adolescents

Parental influence on friendships between native (N = 5,683) and immigrant (N = 3,371) adolescents (aged ± 15) was investigated with the CILS4EU data of pupils in German and Dutch school classes (N = 446) and parents. The researchers examined whether parents affect friendships across group boundaries by shaping the structural opportunities to establish out‐group friends and their children's out‐group attitudes. The results show that if parents have more out‐group friends and if they consider it less important to maintain in‐group traditions, their children have more out‐group friends. Part of this relationship is mediated by children's out‐group attitudes. Some evidence is found that the opportunity structure mediates the relationship between parental characteristics and adolescent out‐group friendship.     

ADHD and Brain Anatomy: What Do Academic Textbooks Used in the Netherlands Tell Students?

Studies of brain size of children classified with ADHD appear to reveal smaller brains when compared to ‘normal’ children. Yet, what does this mean? Even with the use of rigorously screened case and control groups, these studies show only small, average group differences between children with and without an ADHD classification. However, academic textbooks used in the Netherlands often portray individual children with an ADHD classification as having a different, malfunctioning brain that necessitates medical intervention. This conceptualisation of ADHD might serve professional interests, but not necessarily the interests of children.     

Depression and Anxiety Symptoms in Female Adolescents: Relations with Parental Psychopathology and Parenting Behavior

Parental psychopathology and parenting behavior are known to be related to adolescents depression and anxiety, but unique roles of mothers and fathers are not clear. Our aim was to examine the relation of maternal and paternal psychopathology, emotional support, and respect for autonomy, and their interaction to depression and anxiety symptoms in adolescents. In total, 142 female adolescents participated, together with 138 mothers and 113 fathers. Data were analyzed using latent growth curve modeling. Paternal emotional support was negatively related to adolescent baseline level of depression and anxiety symptoms. Further, we found that there was a positive association between respect for autonomy and depression symptoms in adolescents for higher levels of paternal symptoms of psychological problems.     

The (non) gradual association of popularity with peer‐nominated and observed behavior in a cooperative and competitive context

Popularity among peers might be related to behavior in gradual or non‐gradual ways. In this research, a popularity subgroups approach was used to examine whether some behaviors were associated with only specific levels of popularity. Moreover, observational data in popularity research is valuable yet scarce. This research, therefore, also examined the association between popularity and observed behavior in a cooperative and competitive setting. In total, 182 early adolescents (58.2% girls, M_age = 10.7 years) completed peer nominations and were observed during a cooperative and a competitive task in groups of four. Results show that affective ties increased gradually with increasing popularity, but that relational aggression, bullying and attention‐attracting qualities distinguished popular adolescents from other early adolescents, and victimization distinguished unpopular adolescents from the other early adolescents. Observations showed that high popularity was defined by high levels of negative behavior, prosocial resource control, skillful leadership, and influence, with the effect of popularity on influence being stronger in the cooperative than the competitive setting. Using multiple methods, and taking context into account, a more complete behavioral profile of different levels of popularity is provided.     

Dynamic Pricing with Constant Demand Elasticity

The celebrated model of Gallego and van Ryzin is specialized to the case of constant elasticity of demand. A closed form is developed, which has an even simpler form than that arising with exponential demand and which possesses an excellent approximation. In this environment, monopoly is efficient, which means that all the behavior usually attributed to monopoly pricing is actually a consequence of efficient pricing and would arise even in a perfectly competitive environment. If the initial supply is not too large, consumers have no incentive to delay their purchases to get a lower price at the average inventory prevailing at any time.     

Motivating talents in Thai and Malaysian service firms

Talent development in Thailand and Malaysian service firms has become a prioritized human resource management practice as these societies move toward knowledge-based economies. This paper discusses talent management in the social, organizational and managerial context of firms in Thailand and Malaysia, and argues that such structures often counterbalance investments made in talent development. The paper concludes that new human resource management practices do not produce a difference per se. It is the mindset and attitude of various managers that makes the difference. The learning for practitioners is that they need to adapt existing social and organizational structures to their new human resource management practices. The paper is based mainly on qualitative interviews with human resource managers from Thai and Malaysian service firms.     

Incorporating Neighborhood Choice in a Model of Neighborhood Effects on Income

Studies of neighborhood effects often attempt to identify causal effects of neighborhood characteristics on individual outcomes, such as income, education, employment, and health. However, selection looms large in this line of research, and it has been argued that estimates of neighborhood effects are biased because people nonrandomly select into neighborhoods based on their preferences, income, and the availability of alternative housing. We propose a two-step framework to disentangle selection processes in the relationship between neighborhood deprivation and earnings. We model neighborhood selection using a conditional logit model, from which we derive correction terms. Driven by the recognition that most households prefer certain types of neighborhoods rather than specific areas, we employ a principle components analysis to reduce these terms into eight correction components. We use these to adjust parameter estimates from a model of subsequent neighborhood effects on individual income for the unequal probability that a household chooses to live in a particular type of neighborhood. We apply this technique to administrative data from the Netherlands. After we adjust for the differential sorting of households into certain types of neighborhoods, the effect of neighborhood income on individual income diminishes but remains significant. These results further emphasize that researchers need to be attuned to the role of selection bias when assessing the role of neighborhood effects on individual outcomes. Perhaps more importantly, the persistent effect of neighborhood deprivation on subsequent earnings suggests that neighborhood effects reflect more than the shared characteristics of neighborhood residents: place of residence partially determines economic well-being.
