Christians and Muslims Faced with the Wrath of Abū Marwān al-Yuḥānisī, a Thirteenth-Century “Friend of God”

This article examines the nature of the wrath of Abū Marwān al-Yu[hdot]ānisī, a thirteenth-century Andalusi saint, and the protagonist of the Tu?fat al-mughtarib of al-Qashtālī. I have divided the study into two main parts. The first sets out and analyses various occasions on which the saint committed violent acts against Christians. Two of them died as a consequence of these aggressions. All the cases in this first part took place in the Muslim East during the saint's stay in this area. The second part examines cases of violence committed against Muslim people from al-Andalus. The victims suffered the consequences of the wrath of the saint, although he was not directly involved in the aggressions themselves. The stories are narrated by al-Yu[hdot]ānisī himself, and we do not know whether they really took place. Regarding these manifestations of violence, the hagiographic sources not only justify all the violent acts committed by the saint, murder included, but they present the saint to society as an “example” to follow, and indeed as a “hero”.     

Comparison of split double and triple twists in pair figure skating

In this study, we compared the kinematic variables of the split triple twist with those of the split double twist to help coaches and scientists understand these landmark pair skating skills. High-speed video was taken during the pair short and free programmes at the 2002 Salt Lake City Winter Olympics and the 2003 International Skating Union Grand Prix Finals. Three-dimensional analyses of 14 split double twists and 15 split triple twists from eleven pairs were completed. In spite of considerable variability in the performance variables among the pairs, the main difference between the split double twists and split triple twists was an increase in rotational rate. While eight of the eleven pairs relied primarily on an increased rotational rate to complete the split triple twist, three pairs employed a combined strategy of increased rotational rate and increased flight time due predominantly to delayed or lower catches. These results were similar to observations of jumps in singles skating for which the extra rotation is typically due to an increase in rotational velocity; increases in flight time come primarily from delayed landings as opposed to additional height during flight. Combining an increase in flight time and rotational rate may be a good strategy for completing the split triple twist in pair skating.     

The relationship between selected body composition variables and muscular endurance in women

The primary purpose of this study was to determine if muscular endurance is affected by referenced waist circumference groupings, independent of body mass and subcutaneous abdominal fat, in women. This study also explored whether selected body composition measures were associated with muscular endurance. Eighty-four women were measured for height, weight, body mass index (BMI), waist circumference (WC), and abdominal skinfold thickness (SFAB) and performed 60-s sit-ups (SU) and maximal push-ups (PU) tests. Mean differences in SU and PU scores were tested across three groups based on WC as follows: WCG1 < 70 cm; WCG2 between 70 and 89 cm; WCG3 > or = 90 cm. There were no significant differences in SU and PU scores between WCG1 and WCG2. WCG3 had significantly lower SU and PU scores compared to the other groups. After adjusting for the influence of SFAB, BMI, and weight, the differences disappeared. The regression analysis revealed a two-variable (BMI and SFAB) model that accounted for the variation in SU performance. For PU, only BMI loaded into the regression model. The results of this study suggest that women with a WC > or = 90 cm have decreased muscular endurance compared to their lower WC counterparts. This difference is related to higher body masses.     

Self-citations as strategic response to the use of metrics for career decisions

There is limited knowledge on the extent to which scientists may strategically respond to metrics by adopting questionable practices, namely practices that challenge the scientific ethos, and the individual and contextual factors that affect their likelihood. This article aims to fill these gaps by studying the opportunistic use of self-citations, i.e. citations of one’s own work to boost metric scores. Based on sociological and economic literature exploring the factors driving scientists’ behaviour, we develop hypotheses on the predictors of strategic increase in self-citations. We test the hypotheses in the Italian Higher Education system, where promotion to professorial positions is regulated by a national habilitation procedure that considers the number of publications and citations received. The sample includes 886 scientists from four of science’s main disciplinary sectors, employs different metrics approaches, and covers an observation period beginning in 2002 and ending in 2014. We find that the introduction of a regulation that links the possibility of career advancement to the number of citations received is related to a strong and significant increase in self-citations among scientists who can benefit the most from increasing citations, namely assistant professors, associate professors and relatively less cited scientists, and in particular among social scientists. Our findings suggest that while metrics are introduced to spur virtuous behaviours, when not properly designed they favour the usage of questionable practices.     

The role of allocentrism on perceptions and reactions to congruity

We investigated how allocentrism, or the tendency to emphasize in-group attributes was related to the amount and the kind (intrinsic vs. extrinsic) of congruity perceived between own and in-group goals. School teachers (N=114) rated the importance of own and coworkers’ intrinsic and extrinsic goals and completed measures of allocentrism and coworker satisfaction. As predicted, allocentrism was positively correlated with extrinsic goal congruity. In general, increasing congruity on intrinsic goals was related to higher coworker satisfaction. However, there were individual differences in reactions to congruity: high allocentrics who perceived congruity on both, intrinsic and extrinsic goals were more satisfied than those who perceived high congruity only on extrinsic goals.     

Patient-based benefit-risk assessment of medicines: development,refinement, and validation of a content search strategy to retrieve relevant studies

Introduction:Poor indexing and inconsistent use of terms and keywords may prevent efficient retrieval of studies on the patient-based benefit-risk assessment (BRA) of medicines. We aimed to develop and validate an objectively derived content search strategy containing generic search terms that can be adapted for any search for evidence on patient-based BRA of medicines for any therapeutic area.Methods:We used a robust multistep process to develop and validate the content search strategy: (1) we developed a bank of search terms derived from screening studies on patient-based BRA of medicines in various therapeutic areas, (2) we refined the proposed content search strategy through an iterative process of testing sensitivity and precision of search terms, and (3) we validated the final search strategy in PubMed by firstly using multiple sclerosis as a case condition and secondly computing its relative performance versus a published systematic review on patient-based BRA of medicines in rheumatoid arthritis.Results:We conceptualized a final search strategy to retrieve studies on patient-based BRA containing generic search terms grouped into two domains, namely the patient and the BRA of medicines (sensitivity 84%, specificity 99.4%, precision 20.7%). The relative performance of the content search strategy was 85.7% compared with a search from a published systematic review of patient preferences in the treatment of rheumatoid arthritis. We also developed a more extended filter, with a relative performance of 93.3% when compared with a search from a published systematic review of patient preferences in lung cancer.
