Politics,democratic action,and solidarity

I agree with the critique of rationalism proposed by Spinosa, Flores, and Dreyfus in ‘Disclosing New Worlds’. Today the defence of democracy requires us to understand that allegiance to democratic institutions can only rest on identification with the practices, the language‐games, and the discourses which are constitutive of the democratic ‘form of life’, and that it is not a question of providing them with a rational justification. My comments are developed in two directions. First, as a development of their thesis concerning the centrality of practices, I suggest that in order to grasp the present crisis of democratic forms of individuality we can learn a lot from Nietzsche's analysis of ‘nihilism’. Second, I point to a dimension which I consider to be missing in the perspective put forward in the article. It fails to take account of the fact that the constitution of a ‘we’ always requires the determination of a ‘them’. This, in my view, has important consequences for the relation between solidarity and politics. I conclude by arguing for the need to introduce an agonistic element in the view of solidarity, and for the crucial role of the category of the adversary in a pluralist democracy whose aim is to transform antagonism into agonism.     

Restrained eaters act on impulse

Impulsivity and bulimic symptoms often go together. It is not only the eating behaviour of bulimics that is impulsive; many studies show that the eating disorder frequently is accompanied by non-eating related impulsive behaviours like substance abuse, self-harm or theft. This co-morbidity suggests that there might be a more basic lack of inhibitory control that makes someone vulnerable for both the bulimic symptoms and the other impulsive behaviours. The present study tested whether an analogous group of 34 restrained eaters showed a basic inhibitory control deficit by using a stop-signal task, compared to 29 control women. It was found that the restrained eaters were significantly worse in inhibiting their basic non-food related motor responses than unrestrained eaters. Food exposure during the task did not affect motor performance. A fundamental lack of general response inhibition might play a role in the development of a specific eating disinhibition.     

The capacity to generate alternative ideas is more important than inhibition for logical reasoning in preschool-age children

There is little consensus about the nature of logical reasoning and, equally important, about how it develops. To address this, we looked at the early origins of deductive reasoning in preschool children. We examined the contribution of two factors to the reasoning ability of very young children: inhibitory capacity and the capacity to generate alternative ideas. In a first study, a total of 32 preschool children were all given generation, inhibition, and logical reasoning measures. Logical reasoning was measured using knowledge-based premises such as “All dogs have legs,” and two different inferences: modus ponens and affirmation of the consequent. Results revealed that correctly reasoning with both inferences is not related to the measure of inhibition, but is rather related to the capacity to generate alternative ideas. In a second study, 32 preschool children were given either the generation or the inhibition task before the logical reasoning measure. Results showed that receiving the generation task beforehand significantly improved logical reasoning compared to the inhibition task given beforehand. Overall, these results provide evidence for the greater importance of idea generation in the early development of logical reasoning.     

Interactions between inferential strategies and belief bias

The dual strategy model of reasoning proposed by Verschueren, Schaeken, and d’Ydewalle (Thinking & Reasoning, 11(3), 239–278, 2005a; Memory & Cognition, 33(1), 107–119, 2005b) suggests that people can use either a statistical or a counterexample-based strategy to make deductive inferences. Subsequent studies have supported this distinction and investigated some properties of the two strategies. In the following, we examine the further hypothesis that reasoners using statistical strategies should be more vulnerable to the effects of conclusion belief. In each of three studies, participants were given abstract problems used to determine strategy use and three different forms of syllogism with believable and unbelievable conclusions. Responses, response times, and feeling of rightness (FOR) measures were taken. The results show that participants using a statistical strategy were more prone to the effects of conclusion belief across all three forms of reasoning. In addition, statistical reasoners took less time to make inferences than did counterexample reasoners. Patterns of variation in response times and FOR ratings between believable and unbelievable conclusions were very similar for both strategies, indicating that both statistical and counterexample reasoners were aware of conflict between conclusion belief and premise-based reasoning.     

Developing a measure of interpretation bias for depressed mood: An ambiguous scenarios test

The tendency to interpret ambiguous everyday situations in a relatively negative manner (negative interpretation bias) is central to cognitive models of depression. Limited tools are available to measure this bias, either experimentally or in the clinic. This study aimed to develop a pragmatic interpretation bias measure using an ambiguous scenarios test relevant to depressed mood (the AST-D).¹ In Study 1, after a pilot phase (N = 53), the AST-D was presented via a web-based survey (N = 208). Participants imagined and rated each AST-D ambiguous scenario. As predicted, higher dysphoric mood was associated with lower pleasantness ratings (more negative bias), independent of mental imagery measures. In Study 2, self-report ratings were compared with objective ratings of participants’ imagined outcomes of the ambiguous scenarios (N = 41). Data were collected in the experimental context of a functional Magnetic Resonance Imaging scanner. Consistent with subjective bias scores, independent judges rated more sentences as negatively valenced for the high versus low dysphoric group. Overall, results suggest the potential utility of the AST-D in assessing interpretation bias associated with depressed mood.     

Work engagement and task performance within a global Dutch ICT-consulting firm: The mediating role of innovative work behaviors

The information and communication technology (ICT) sector within the Netherlands is a major driver of globalization, the country’s economic growth and innovation. The Dutch ICT sector’s performance is increasingly becoming dependent upon employee driven innovations in order to address the needs of the sectors they service. In other words, the ICT sector within the Netherlands is largely dependent upon the performance and innovative capacity of its employees; both of which are functions of employee engagement. Given the high demand, and low supply of talent within this sector, ICT organizations need to develop innovative ways to enhance the performance capacities of its people. Developing an engaged and highly innovative workforce seems to be an efficient way to activate employees’ performance. As such, the aim of this paper was to investigate the mediating function of employee driven innovative work behaviors in the relationship between work engagement and task performance within the a Dutch ICT consulting firm. A cross-sectional survey-based research design, employing a census-based sampling method, was employed to obtain data from a global ICT consulting firm within the Netherlands (n = 232). The Utrecht Work Engagement Scale, the Innovative Work Behavior Scale and the Task Performance Scale was used to assess the associative subjective experiences of ICT employees. The results showed that work engagement is a significant driver for innovative work behaviors, which in turn affects the task performance of employees. Further, innovative work behaviors are therefore important to translate the engaging energies of employees into performance. This paper discusses the theoretical and practical implications of these findings.

     

Testing for negligible interaction: A coherent and robust approach

Researchers often want to demonstrate a lack of interaction between two categorical predictors on an outcome. To justify a lack of interaction, researchers typically accept the null hypothesis of no interaction from a conventional analysis of variance (ANOVA). This method is inappropriate as failure to reject the null hypothesis does not provide statistical evidence to support a lack of interaction. This study proposes a bootstrap‐based intersection–union test for negligible interaction that provides coherent decisions between the omnibus test and post hoc interaction contrast tests and is robust to violations of the normality and variance homogeneity assumptions. Further, a multiple comparison strategy for testing interaction contrasts following a non‐significant omnibus test is proposed. Our simulation study compared the Type I error control, omnibus power and per‐contrast power of the proposed approach to the non‐centrality‐based negligible interaction test of Cheng and Shao (2007, Statistica Sinica, 17, 1441). For 2 × 2 designs, the empirical Type I error rates of the Cheng and Shao test were very close to the nominal α level when the normality and variance homogeneity assumptions were satisfied; however, only our proposed bootstrapping approach was satisfactory under non‐normality and/or variance heterogeneity. In general a × b designs, although the omnibus Cheng and Shao test, as expected, is the most powerful, it is not robust to assumption violation and results in incoherent omnibus and interaction contrast decisions that are not possible with the intersection–union approach.     

Negotiating Identity: Three Events that Weaken the Maternal Identity of Addicted Law-Breaking Women

This qualitative study aimed to comprehend how mothers experienced and built their maternal identity throughout their lives. Thirty-eight semi-structured interviews were conducted with drug-using and law-breaking mothers. Results showed that three events were significant for participants: pregnancies, loss of custody, and incarceration. As each event challenged their maternal identity, they questioned their substance use and their criminal involvement. Our results suggest that these events represent key moments to encourage their growing awareness and to foster changes in their deviant lifestyle. We conclude this article by discussing interventions possible for each of these important moments in these mothers’ lives.
