Alcohol may not cause partner violence but it seems to make it worse: a cross national comparison of the relationship between alcohol and severity of partner violence.

This study assesses whether severity of physical partner aggression is associated with alcohol consumption at the time of the incident, and whether the relationship between drinking and aggression severity is the same for men and women and across different countries. National or large regional general population surveys were conducted in 13 countries as part of the GENACIS collaboration. Respondents described the most physically aggressive act done to them by a partner in the past 2 years, rated the severity of aggression on a scale of 1 to 10, and reported whether either partner had been drinking when the incident occurred. Severity ratings were significantly higher for incidents in which one or both partners had been drinking compared to incidents in which neither partner had been drinking. The relationship did not differ significantly for men and women or by country. We conclude that alcohol consumption may serve to potentiate violence when it occurs, and this pattern holds across a diverse set of cultures. Further research is needed that focuses explicitly on the nature of alcohol's contribution to intimate partner aggression. Prevention needs to address the possibility of enhanced dangers of intimate partner violence when the partners have been drinking and eliminate any systemic factors that permit alcohol to be used as an excuse. Clinical services for perpetrators and victims of partner violence need to address the role of drinking practices, including the dynamics and process of aggressive incidents that occur when one or both partners have been drinking.

Per aprendre anglès, quan abans millor? L'aprenentatge de l'anglès com a llengua estrangera. When Learning English, is it a case of 'The earlier the better?' Learning English as a foreign Language

En contra del que molts pares i mestres pensen, i en contra del que s'ha trobat en contextos d'adquisició natural de segones llengües i d'immersió, començar al més aviat possible l'aprenentatge d'idiomes, sobretot pel que fa a les tasques cognitivament més exigents, com l'escriptura, no sembla l'opció més eficaç. Els resultats del Grup de Recerca en Adquisició de Llengües (GRAL) estudià aprenents d'anglès que començaren als vuit i onze anys i trobaren, sistemàticament, que a llarg termini, després de les mateixes hores d'instrucció, eren els més grans, que havien començat als onze anys, els que obtenien millors resultats en totes les proves orals i escrites d'anglès excepte en alguna de prova de reconeixement fonètic. La maduresa cognitiva dels alumnes més grans i els diferents mecanismes d¿aprenentatge implícit i explícit entre els nens més petits i els adults ajuden a explicar per què només començar abans l'aprenentatge d'idiomes no sembla suficient per obtenir millors resultats.

Looking for Validity or Testing It? The Perils of Stepwise Regression, Extreme-Scores Analysis, Heteroscedasticity, and Measurement Error

When researchers introduce a new test they have to demonstrate that it is valid, using unbiased designs and suitable statistical procedures. In this article we use Monte Carlo analyses to highlight how incorrect statistical procedures (i.e., stepwise regression, extreme scores analyses) or ignoring regression assumptions (e.g., heteroscedasticity) contribute to wrong validity estimates. Beyond these demonstrations, and as an example, we re-examined the results reported by Warwick, Nettelbeck, and Ward (2010) concerning the validity of the Ability Emotional Intelligence Measure (AEIM). Warwick et al. used the wrong statistical procedures to conclude that the AEIM was incrementally valid beyond intelligence and personality traits in predicting various outcomes. In our re-analysis, we found that the reliability-corrected multiple correlation of their measures with personality and intelligence was up to .69. Using robust statistical procedures and appropriate controls, we also found that the AEIM did not predict incremental variance in GPA, stress, loneliness, or well-being, demonstrating the importance for testing validity instead of looking for it.

Percutaneous drainage versus emergency cholecystectomy for the treatment of acute cholecystitis in critically ill patients: does it matter?

Background The aim if this study was to compare percutaneous drainage (PD) of the gallbladder to emergency cholecystectomy (EC) in a well-defined patient group with sepsis related to acute calculous/acalculous cholecystitis (ACC/AAC).Methods Between 2001 and 2007, all consecutive patients of our ICU treated by either PD or EC were retrospectively analyzed. Cases were collected from a prospective database. Percutaneous drainage was performed by a transhepatic route and EC by open or laparoscopic approach. Patients' general condition and organ dysfunction were assessed by two validated scoring systems (SAPS II and SOFA, respectively). Morbidity, mortality, and long-term outcome were systematically reviewed and analyzed in both groups.Results Forty-two patients [median age = 65.5 years (range = 32-94)] were included; 45% underwent EC (ten laparoscopic, nine open) and 55% PD (n = 23). Both patient groups had similar preoperative characteristics. Percutaneous drainage and EC were successful in 91 and 100% of patients, respectively. Organ dysfunctions were similarly improved by the third postoperative/postdrainage days. Despite undergoing PD, two patients required EC due to gangrenous cholecystitis. The conversion rate after laparoscopy was 20%. Overall morbidity was 8.7% after PD and 47% after EC (P = 0.011). Major morbidity was 0% after PD and 21% after EC (P = 0.034). The mortality rate was not different (13% after PD and 16% after EC, P = 1.0) and the deaths were all related to the patients' preexisting disease. Hospital and ICU stays were not different. Recurrent symptoms (17%) occurred only after ACC in the PD group.Conclusions In high-risk patients, PD and EC are both efficient in the resolution of acute cholecystitis sepsis. However, EC is associated with a higher procedure-related morbidity and the laparoscopic approach is not always possible. Percutaneous drainage represents a valuable intervention, but secondary cholecystectomy is mandatory in cases of acute calculous cholecystitis.

Is it the grain size or the characteristic pore size that controls the induced polarization relaxation time of clean sands and sandstones?

There is a wide range of evidence to suggest that permeability can be constrained through of induced polarization measurements. For clean sands and sandstones, current mechanistic models of induced polarization predict a relationship between the low-frequency time constant inferred from induced polarization measurements and the grain diameter. A number of observations do, however, disagree with this and indicate that the observed relaxation behavior is rather governed by the so-called dynamic pore radius L. To test this hypothesis, we have developed a set of new scaling relationships, which allow the relaxation time to be computed from the pore size and the permeability to be computed from both the Cole-Cole time constant and the formation factor. Moreover, these new scaling relationships can be also used to predict the dependence of the Cole-Cole time constant as a function of the water saturation under unsaturated conditions. Comparative tests of the proposed new relationships with regard to various published experimental results for saturated clean sands and sandstones as well as for partially saturated clean sandstones, do indeed confirm that the dynamic pore radius L is a much more reliable indicator of the observed relaxation behavior than grain-size-based models.
