Women as wives and rulers in Martin Luther's theology

This article offers a theological analysis of Martin Luther's complex view on women and their role in society, focusing on his exposition of the narratives of creation and fall in the Lectures on Genesis. Luther's understanding of women is defined by an ostensible paradox. On the one hand, Luther claims that all women are equal to men in relation to God and hold the power to rule over the earth, which they execute as leaders of the household. On the other hand, Luther passes on a traditional view of women being of a weaker nature and argues that wives have to subordinate to their husbands. I interpret this understanding of women as an outcome of Luther's theological anthropology based on his doctrine of justification. Men and women are equal as priests and kings in relation to God and authorized to manage their relationship with him, to teach and pray for others, and to disobey authority that interferes with this faith relation. As sinners, though, they must submit to authority to suppress sin. Both men and women exercise authority through their gender-specific callings in the earthly hierarchies, which constitute God's created order. However, women have to subordinate to their husbands in order to suppress sin. The article discusses whether this complex view on women promoted patriarchal social structures or whether the freedom and equality of the spiritual realm over time filtered through to the role of women in society, paving the way for their liberation.     

Face-based categorization, context-based categorization, and distortions in the recollection of gender ambiguous faces

In three studies, we examined the impact of face-based and context-based categorization in the recollection of gender ambiguous faces. Gender ambiguous faces were created by morphing male and female source faces. In Study 1, the recollection of moderately ambiguous faces (i.e., 70% male-30% female faces and 70% female-30% male faces) was accentuated towards face distracters that were more typical of the spontaneous (i.e., face-based) categorization of these faces. In Study 2, the recollection of extremely ambiguous faces (50% male-50% female faces) was accentuated towards face distracters that were more typical of the gender category suggested by context cues attached to these faces prior to the face presentation. Study 3 relied on the same design as Study 2, but this time context cues were provided after face encoding. In line with predictions, no accentuation effect emerged under the latter conditions. The theoretical and practical implications of these findings are discussed.     

Gaussian model‐based partitioning using iterated local search

The emergence of Gaussian model‐based partitioning as a viable alternative to K‐means clustering fosters a need for discrete optimization methods that can be efficiently implemented using model‐based criteria. A variety of alternative partitioning criteria have been proposed for more general data conditions that permit elliptical clusters, different spatial orientations for the clusters, and unequal cluster sizes. Unfortunately, many of these partitioning criteria are computationally demanding, which makes the multiple‐restart (multistart) approach commonly used for K‐means partitioning less effective as a heuristic solution strategy. As an alternative, we propose an approach based on iterated local search (ILS), which has proved effective in previous combinatorial data analysis contexts. We compared multistart, ILS and hybrid multistart–ILS procedures for minimizing a very general model‐based criterion that assumes no restrictions on cluster size or within‐group covariance structure. This comparison, which used 23 data sets from the classification literature, revealed that the ILS and hybrid heuristics generally provided better criterion function values than the multistart approach when all three methods were constrained to the same 10‐min time limit. In many instances, these differences in criterion function values reflected profound differences in the partitions obtained.     

Can brown lemurs (<Emphasis Type="Italic">Eulemur fulvus</Emphasis>) learn to deceive a human competitor?

In the present study we asked whether lemurs could learn to manipulate information in order to deceive a human competitive trainer. Four brown lemurs were trained to communicate about the location of a hidden reward to a cooperative trainer, who rewarded the subject if he indicated the baited bowl. Next, a competitive trainer was introduced who kept the reward for himself if the subject indicated the baited bowl. In a first experiment, sessions were randomly assigned to be with either the cooperative or competitive trainer. No subject was able to show an efficient tactic with both trainers. In a second experiment, the participation of the two trainers was randomized across the trials for each session. When trials were mixed, one subject significantly chose baited location when interacting with the cooperative trainer, and reliably increased his choices of the unbaited location when presented with the competitive trainer. As with most other primate species tested under the same paradigm, associative learning may explain deceptive pointing by lemurs in this study.     

Money, Work–Life Balance and Autonomy: Why do IT Professionals Choose Self-Employment?

This article deals with the reasons why IT professionals chose self-employment, as well as advantages and drawbacks of this form of employment. A growing number of workers in industrialized countries are now self-employed, most notably in the IT sector. In order to understand this trend better, we carried out a quantitative survey in collaboration with a professional association of independent IT workers in Quebec (Canada). We examined the different reasons why self-employment is attractive for IT professionals, the advantages they experience and the disadvantages they point out. While some authors postulate that self-employment is attractive because it facilitates work–life balance, our results show a strong predominance of the financial advantages and a weak impact of factors related to work–life balance. We also find high levels of job satisfaction, but the effects on work–life balance remain indirect.     

Basic visual perceptual processes in children with typical development and cerebral palsy: The processing of surface,length, orientation,and position

The present study aims to assess how the processing of basic visual perceptual (VP) components (length, surface, orientation, and position) develops in typically developing (TD) children (n = 215, 4–14 years old) and adults (n = 20, 20–25 years old), and in children with cerebral palsy (CP) (n = 86, 5–14 years old) using the first four subtests of the Battery for the Evaluation of Visual Perceptual and Spatial processing in children. Experiment 1 showed that these four basic VP processes follow distinct developmental trajectories in typical development. Experiment 2 revealed that children with CP present global and persistent deficits for the processing of basic VP components when compared with TD children matched on chronological age and nonverbal reasoning abilities.     

When memory shifts toward more typical category exemplars: accentuation effects in the recollection of ethnically ambiguous faces

In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphing program). In all studies, the prevalence of exclusive ethnic features in a face distorted participants' recollections of the face toward faces more typical of the category. Specifically, the recollection of 30% North African (or 30% Asian) faces shifted toward Caucasian source faces, whereas the recollection of 70% North African (or 70% Asian) faces shifted toward North African (Asian) source faces. Memory distortions did not emerge for extremely ambiguous (50%) faces and proved larger on mixed-race than same-race continua (Studies 3 and 4). Memory distortions also emerged with high levels of confidence. The authors elaborate on the theoretical and practical implications of these findings.     

La mesure du stress en milieu professionnel avec l’échelle de stress perçu (Perceived Stress Scale): pertinence des versions en dix et quatre items

This article presents the psychometric qualities of the Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983) in ten- and four-item version. Our objectives are to verify if we find the main results of the literature as regards the ten-item version and to observe if the psychometric properties of the four-item version are enough good to use this questionnaire. The population of the study consists of 16853 employees working in French large companies. The analyses concern the structure of questionnaires, internal consistency, capacity to discriminate from groups of persons according to gender, age group and professional status, and the convergent validity of both versions. Our results show that 1) we find the main psychometric characteristics of the ten- item version described in the literature and 2) the four-item version presents qualities enough good to be used in an estimation of the perceived stress.     

Optimising retention through multiple study opportunities over days: The benefit of an expanding schedule of repetitions

Few studies have investigated how scheduling repeated studies of the same material over several days influences its subsequent retention. The study-phase retrieval hypothesis predicts that, under these circumstances, expanding intervals between repetitions will promote the greatest likelihood that the participant will be reminded of previous occurrences of the item, thus leading to a benefit for subsequent recall. In the present article, participants studied vocabulary pairs that were repeated according to one of three schedules. In the expanding schedule, pairs were presented on days 1, 2 and 13; in the uniform schedule, on days 1, 7 and 13; and in the contracting schedule, on days 1, 12 and 13. Cued-recall was assessed after a retention interval (RI) of 2, 6 or 13 days. Consistent with predictions, the expanding schedule generally led to better performance than the other schedules. However, further analyses suggested that the benefit of an expanding schedule may be greater when the RI is longer.     

Increasing compliance with medical examination requests directed to children with autism: effects of a high-probability request procedure

The purpose of this study was to evaluate the effectiveness of a high-probability (high-p) request sequence as a means of increasing compliance with medical examination tasks. Participants were children who had been diagnosed with autism and who exhibited noncompliance during general medical examinations. The inclusion of the high-p request sequence effectively increased compliance with medical examination tasks. In addition, the procedure was efficient, could be implemented by parents and medical professionals, and did not involve aversive procedures.
