Alcohol use, alcohol-related aggression and intimate partner abuse: a cross-sectional survey of convicted versus general population men in Scotland

Introduction and Aims. Scotland has a particular problem with alcohol, and the links between intimate partner abuse (IPA) and alcohol appear stronger here than elsewhere across Europe. This study explored differences in alcohol use, related aggression and relationship conflict across a number of groups: men convicted for intimate partner abuse, men convicted of general offences and men recruited from community sports teams. Design and Methods. Participants (n = 64) completed three questionnaires exploring their experiences of alcohol use (Alcohol Use Disorders Identification Test, AUDIT); alcohol and aggression (Alcohol Related Aggression Questionnaire, ARAQ-28), and relationship conflict (Revised Conflict Tactics Scale, CTS-2). Results. There were significant differences across the groups in terms of AUDIT and ARAQ-28 scores, IPA and general offenders scored higher than the community sample. CTS-2 scores showed significant differences: both offender groups reported more use of negotiation and psychological abuse, than the community men, and IPA offenders reported causing more physical harm than either general offenders or the community sample. ARAQ-28 scores correlated with psychological abuse for general offenders. Alcohol use was very high across all groups, but the community group did not endorse an aggression-precipitating view of alcohol and did not report high IPA. Discussion and Conclusions. Discussed is the need for cross-cultural research to explore putative mediators and moderators in the relationship between alcohol, aggressiveness and IPA.

Mathematical Game Creation and Play Assists Students in Practicing Newly-Learned Challenging Concepts

Twenty-four high-performing fifth grade students (aged 10 - 11 years) participated in a year-long study in which conditions alternated for six instructional units between lecture-based mathematics instruction and practice through solving additional problems in small groups versus practice through designing and playing mathematics games related to the topic. Students scored similarly on all units at the time of the posttest. Creating games allowed students to examine concepts on their own, making sense of them at a deeper level, avoiding confusion. Game-making may also have made the mathematics more personal, relevant, and interesting. The authors suggest that mathematics teachers consider adding game-making to their strategies for practicing and applying mathematical concepts

A comparison of lead-based and lead-free bullets for shooting sambar deer (Cervus unicolor) in Australia

Context: In response to the toxic health threats posed by lead (Pb), there is currently a focus on transitioning to lead-free bullets for shooting wild animals. Aim: We aimed to quantify the killing efficiency and animal welfare outcomes of lead-based and lead-free (copper-based) bullets for ground-based shooting of sambar deer (Cervus unicolor) in Victoria, south-eastern Australia. Methods: We used shooter-collected data from recreational diurnal hunting and professional nocturnal culling during 2020–2021. Shooters recorded rifle calibre, cartridge type, bullet mass, bullet type, shooting outcomes (miss, wound or kill), shooting distance, flight distance (the distance between where the animal was shot and where it died) as an assumed positive correlate of time to incapacitation, anatomical zones struck by bullets, and frequency of bullet exit wounds. We used flight distance as our response variable, assuming that it is positively correlated with time to incapacitation. To examine the role of several predictor variables (including bullet type) potentially influencing flight distance, the dataset was reduced to those deer killed with a single thoracic shot. Key results: Our data captured shooting events involving 276 deer, with 124 deer shot at with lead-based bullets and 152 with copper-based bullets. Most (87%) of the deer were killed with a single shot. The frequency of non-fatal wounding was <4% for both bullet types and there was no distinct difference in the probability of a single shot kill for deer shot with either bullet type. For those deer killed with a single thoracic shot (n = 198), there was no evidence that bullet energy or shooting distance influenced flight distance. After accounting for differences in terminal kinetic energy, the mean flight distance of deer shot with lead-free bullets (35 m) was 56% greater than that of deer shot with lead-based bullets (22 m). Conclusions: Lead-based and lead-free bullets produced similar animal welfare outcomes for shooting sambar deer. Implications: A transition to lead-free ammunition for shooting sambar deer would have minimal impact on efficiency or animal welfare outcomes

Late presentation of a mucinous ovarian adenocarcinoma which was initially diagnosed as a primary pancreatic carcinoma: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Adenocarcinoma of the ovary is an aggressive neoplasm which often metastasizes to the lung or liver. Metastases rarely occur to the pancreas, but a tissue diagnosis is required to confirm this event. Although most tumors of the pancreas are primary pancreatic neoplasms, metastatic lesions have been reported most commonly as arising from renal cell carcinoma.</p> <p>Case presentation</p> <p>We report the case of a 51-year-old Caucasian woman with ovarian mucinous adenocarcinoma with metastasis to the head of the pancreas that was originally misdiagnosed as a pancreatic primary tumor.</p> <p>Conclusion</p> <p>Mucinous ovarian adenocarcinomas rarely metastasize to the pancreas. New pancreatic lesions should be investigated through tissue biopsy and tumor markers, while keeping an open-minded differential diagnosis to avoid a misdiagnosis or a delay in treatment.</p
