Within the scope of judicial decisions, approaches to distinguish between true and fabricated statements have been of particular importance since ancient times. Although methods focusing on “prototypical” deceptive behavior (e.g., psychophysiological phenomena, nonverbal cues) have largely been rejected with regard to validity, content-based techniques constitute a promising approach and are well established within the applied forensic context. The basic idea of this approach is that experience-based and non-experience-based statements differ in their content-related quality. In order to test the validity of the most prominent content-based techniques, Criteria-Based Content Analysis (CBCA) and Reality Monitoring (RM), we conducted a comprehensive meta-analysis on English- and German-language studies. Based on a variety of decision criteria, 56 studies were included revealing an overall effect size of g = 1.03 (95% CI [0.78, 1.27], Q = 420.06, p < .001, I² = 92.48%, N = 3429). There was no significant difference in the effectiveness of CBCA and RM. Additionally, we investigated a number of moderator variables such as characteristics of participants, statements, and judgment procedures, as well as general study characteristics. Results showed that the application of all CBCA criteria outperformed any incomplete CBCA criteria set. Furthermore, statement classification based on discriminant functions revealed higher discrimination rates than decisions based on sum scores. Finally, unpublished studies showed higher effect sizes than studies published in peer-reviewed journals. All results are discussed in terms of their significance for future research (e.g., developing standardized decision rules) and practical application (e.g., user training, applying complete criteria set).

This study examines the validity of the complex problemsolving (CPS) test MicroDYN by investigating a) the relation between its dimensions – rule identification (exploration strategy), rule knowledge (acquired knowledge), rule application (control performance) – and working memory capacity (WMC), and b) whether CPS predicts school grades in different domains beyond WMC. A sample of n=393 German high school students (age M=17.07, SD=1.12) completed the computer-based tests Memory Updating Numerical and the CPS scenario MicroDYN. Using structural equation modeling, WMC predicted rule knowledge and rule application, which remained substantially correlated after controlling forWMC. Rule knowledge predicted school grades in science and social studies beyondWMC, but not in language subjects. Explanations for the differential concurrent validity of CPS as well as prerequisites for valid CPS assessment are discussed. [less ▲]

As a histone deacetylase inhibitor, valproic acid (VPA) is a candidate for anticancer therapy. Besides, VPA exhibits various mechanisms of action and its effects on the molecular basis of hematopoiesis remain unclear. To study the effects of VPA on the hematopoietic system, we performed microarray analysis using K562 cells treated with 1mM VPA over a 72h time course. The association between gene ontology (GO) terms and the lists of differentially expressed genes was tested using the Bioconductor package GOstats. Enrichment analysis for cellular differentiation pathways was performed based on manually curated gene lists. Results from microarray analysis were confirmed by studying cell differentiation features at the molecular and cellular levels using other hematopoietic cell lines as well as hematopoietic stem/progenitor CD34(+) cells. Microarray analysis revealed 3440 modulated genes in the presence of VPA. Genes involved in the granulo-monocytic differentiation pathway were up-regulated while genes of the erythroid pathway were down-regulated. This was confirmed by analyzing erythrocytic and myeloid membrane markers and lineage-related gene expression in HEL, MEG01, HL60 as well as CD34(+) cells. Moreover, GATA-1 and its co-factors (FOG1, SP1) were down-regulated, while myelopoiesis activator PU.1 was up-regulated, in agreement with an inhibition of erythropoiesis. Our functional profiling and cell phenotyping approach demonstrates that VPA is able to alter hematopoietic homeostasis by modifying the cell population balance in the myeloid compartment. This may lead to a potential failure of erythropoiesis in patients with cancer or chronic inflammatory diseases having a well-described propensity to anemia. [less ▲]

Financial returns series typically exhibit excess kurtosis and volatility clustering. GARCH models are often applied to describe these two stylised facts. Nevertheless, applications of these processes to stock returns have shown that they cannot capture all excess kurtosis, high Jarque-Bera and inherent non-linearity. The aim of this work is to suggest a new non-linear framework for the calculation of the Value-at-Risk. As it has been demonstrated in Kyrtsou and Terraza V. (2004) the use of a mixed non-linear model in the estimation of VaR can improve the obtained results. In this paper we apply the traditional VaR-GARCH and the VaR-Mackey-Glass-GARCH models both to the initial and the filtered Nikkei returns series without outliers. [less ▲]

Starting out from the frequent empirical finding that immigrants exhibit higher educational aspirations than non-immigrants, we analyse the role of immigrants’ value of education, i.e. the subjective belief that education is beneficial for one’s life, in idealistic and realistic educational aspirations in four distinct institutional settings, comparing Sweden, Germany, the Netherlands and England. While the first part of the analyses relates to how immigrants differ from non-immigrants in the value they assign to education, the second part centres on country differences considering immigrant integration policies and education systems as crucial factors. A third part relates to the links between the value of education and educational aspirations to gain some insight into how the value of education may contribute to educational decisions. Analyses are based on longitudinal data of the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU). While results show that immigrants assign a higher value to education, the value of education does play a minor role in idealistic and realistic educational aspirations. The results of the country comparison are rather ambivalent, including very weak support for the argument that immigrants strive for education to a higher extent in countries with less favourable conditions.

This paper investigates whether relative corporate sustainability as measured by the SAM sustainability ranking and sustainability reporting in terms of Global Reporting Initiative (GRI) application levels are associated with a higher market valuation. We conduct a value relevance study for the 600 largest European companies with the Feltham and Ohlson valuation model as a reference point. Our results indicate that for the observation period 2001 to 2011, the association between corporate sustainability and market value is positive. The empirical evidence of a positive relationship between GRI reporting and market value is statistically significant in some but not all of the model specifications. We find no evidence of interaction between the value relevance of corporate sustainability and sustainability reporting, nor do we find any positive effect of external assurance on the capital market perception of GRI application levels. Our results support the notion that conducting business in accordance with ethical norms is also a shareholder valueincreasing business strategy. However, it is not possible to verify the information given in sustainability reports through external assurance. [less ▲]
