Congruence of group therapist and group member alliance judgments in emotionally focused group therapy for binge eating disorder.
2016
We used West and Kenny's (2011) Truth-and-Bias (TB) model to examine how accurately group therapists' judge their group members' alliances, and the effects of therapist-patient congruence in alliance ratings on patient outcomes. Were considered: (a) directional bias - therapists' tendency to over- or underrate their clients' alliances, (b) truth strength - clients' alliance ratings, and (c) bias strength - therapists' tendency to conflate their alliance ratings for a specific group member with the average alliance ratings for the other members of the group. There were 118 obese adult patients with binge-eating disorder that were treated by 8 therapists with Emotionally Focused Group Therapy…
Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample
2017
While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model …
Effectiveness of child protection practice models : a systematic review
2020
Background Attempts to improve child protection outcomes by implementing social work practice models embedded in a particular theory and practice approach, have increased internationally over the past decade. Objective To assess the evidence of the effectiveness of child protection practice models in improving outcomes for children and families. Participants and setting Children < 18 years and their families involved in child protection services. Methods A systematic review was conducted to synthesize evidence regarding the effectiveness of child protection practice models. Systematic searches across 10 electronic databases and grey literature were conducted to identify quasi-experimental s…
Stock Volatility Predictability in Bull and Bear Markets
2020
Recent literature on stock return predictability suggests that it varies substantially across economic states being strongest during bad economic times. In line with this evidence, we document that stock volatility predictability is also state dependent. In particular, using a large data set of high-frequency data on individual stocks and a few popular time-series volatility models, in this paper we comprehensively examine how volatility forecastability varies across bull and bear states of the stock market. We find that the volatility forecast horizon is substantially longer when the market is in a bear state than when it is in a bull state. In addition, the volatility forecast accuracy is…
Readability and the Web
2012
Readability indices measure how easy or difficult it is to read and comprehend a text. In this paper we look at the relation between readability indices and web documents from two different perspectives. On the one hand we analyse how to reliably measure the readability of web documents by applying content extraction techniques and incorporating a bias correction. On the other hand we investigate how web based corpus statistics can be used to measure readability in a novel and language independent way.
AUDIENCE SUPPORT DECISIONS IN IN THE AFTERMATH OF A SOCIAL SCANDAL: THE ROLES OF LEGITIMACY AND REPUTATION
2014
Constituent audience evaluations and decisions regarding whether to continue to support a corporation after it has been perceived as culpable for socially irresponsible behaviour following corporate social irresponsibility (CSI) scandals are coin of the realm in selecting which firms (or which parts of a firm) will be able to survive a CSI-scandal. Research has largely taken for granted that CSI leads to the loss of corporate legitimacy and, consequently, of constituent audience support. Though legitimacy may be reconstructed, empirics suggest this is a necessary but insufficient condition for the maintenance of audience support. Adopting the evaluators’ perspective, this study focuses on t…
Guía para la incorporación de la perspectiva de género en la docencia en Sociología, Economía y Ciencias Políticas
2019
Sociology has constructed a male worldview that entails a biased interpretation of social reality. For its part, the traditional economy has made invisible the dependence of the commercial sphere of the domestic sphere. And in the field of political science, we also find many gender biases in basic concepts such as justice, equality or citizenship. This article, based on the work done by the authors in the Guia per a una docència universitària amb perspectiva de gènere de Sociologia, Economia i Ciència Política, offers some proposals, teaching resources and consultation tools to introduce the gender perspective in teaching, knowledge transfer and research in these disciplines.
On Response Bias in the Face Congruency Effect for Internal and External Features
2017
Some years ago Cheung et al. (2008) proposed the complete design (CD) for measuring the failure of selective attention in composite objects. Since the CD is a fully balanced design, analysis of response bias may reveal potential effects of the experimental manipulation, the stimulus material, and/or attributes of the observers. Here we used the CD to prove whether external features modulate perception of internal features with the context congruency paradigm (Nachson et al., 1995; Meinhardt-Injac et al., 2010) in a larger sample of N = 303 subjects. We found a large congruency effect (Cohen's d = 1.78), which was attenuated by face inversion (d = 1.32). The congruency relation also strongly…
Coupled conditional backward sampling particle filter
2020
The conditional particle filter (CPF) is a promising algorithm for general hidden Markov model smoothing. Empirical evidence suggests that the variant of CPF with backward sampling (CBPF) performs well even with long time series. Previous theoretical results have not been able to demonstrate the improvement brought by backward sampling, whereas we provide rates showing that CBPF can remain effective with a fixed number of particles independent of the time horizon. Our result is based on analysis of a new coupling of two CBPFs, the coupled conditional backward sampling particle filter (CCBPF). We show that CCBPF has good stability properties in the sense that with fixed number of particles, …
Biaixos atencionals en l’esquizofrènia: una revisió bibliogràfica
2018
Antecedents: En la present revisió s’analitzen diverses investigacions on s’estudien els biaixos atencionals en el processament de la informació d’estímuls amb diferent valència emocional en persones amb esquizofrènia. Metodologia: Bases de dades PubMed i PsycINFO, articles complets en anglés, que utilitzen participants adults. L’objectiu és analitzar articles des de l’any 2000 al 2016 on s’estudien els biaixos atencionals en l’esquizofrènia. Pregunta de recerca: Existeixen biaixos atencionals en el processament de la informació davant estímuls amb diferent valència emocional ‒càrrega emocional agradable, desagradable o neutra‒ en persones amb esquizofrènia?
