Willingness To Help

Individuals prefer helping some people more that others when it comes to finding a mate, and these preferences depend on whether long- or short-term mates are considered. Study 1 ( N = 108) examined three theoretical frameworks (inclusive fitness, reciprocal altruism, and parental investment) for understanding why individuals would be more willing to help some individuals find mates instead of others. College participants reported how willing they were to help different types of individuals (e.g., sister, stranger) find a mate. When considering willingness to help others find a long-term mate, people preferred kin over nonkin, supporting an inclusive fitness model. However, when considering willingness to help others find short-term mates, people preferred helping people their own age, supporting a reciprocal altruism model. Study 2 ( N = 143) replicated this age-cohort effect. Although rates of willingness to help others find mates were generally low, people were more likely to help others find a long-term mate than a short-term one.

Physical Features

Identifying reproductive opportunities and intrasexual rivals has necessitated the evolution of sensitivity to features diagnostic of mate value. In determining the presence of good genes through physical features, individuals may additionally infer targets’ short- and long-term mating motives. This study tested how individuals perceive men and women’s mating intentions through physical features conducive to reproductive goals. Participants evaluated preferred mating strategies of male and female targets varying in size of sex-typical features (i.e., muscles or breasts) and adiposity. Greater adiposity connoted long-term mating interest. Large muscles and breasts connoted short-term mating interests. We frame results from an affordance management framework with respect to inferences regarding parental investment and intrasexual competition.

AbstractReferendums are rare events in most parliamentary democracies, and when they do occur they present an analytical puzzle. Are they such unusual events that they fall outside of the theoretical frameworks familiar to students of elections? Or, even though they enter political life infrequently, can they be understood as something not entirely foreign to our thinking about electoral politics? Here, we argue that voting in referendums such as the constitutional referendum of October 26, 1992 is driven by many of the same factors that are present in elections—parties, leaders, issues, a campaign timetable, the interplay between long- and short-term forces and the dynamic of the campaign itself. In spite of their unique features, referendums can be understood in terms of models of voting behaviour familiar to students of elections in Canada and elsewhere. But, devoid of some of the long-term partisan and social anchors which play a role in elections, their outcome is even more dependent on the short-term elements of the campaign. As such, referendums are subject to greater volatility and uncertainty than that typically found in ordinary parliamentary elections.

Context Dependent

Previous studies suggest that humans use facial characteristics as a cue of kinship in a context-dependent manner: a self-resembling face is preferred as a target of cooperation because cooperating with kin enhances inclusive fitness, but avoided as a mating partner because mating with kin increases the risk of inbreeding. Another line of evidence indicates that children internalize faces of their family members and later use them as a referent with which faces of others are compared. Using digital morphing techniques, we conduct an experiment in a village in Sumba, Indonesia, to investigate effects of facial self- or parent-resemblance on perceived attractiveness of opposite-sex faces in the context of a long-term or short-term relationship. Our results show that females prefer a male face not resembling themselves and males prefer a female face not resembling their mothers, both in the long-term context.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.

Previous short term toxicological studies of one to two weeks duration have demonstrated that MDL 19,660 (5-(4-chlorophenyl)-2,4-dihydro-2,4-dimethyl-3Hl, 2,4-triazole-3-thione), an antidepressant drug, causes a dose-related thrombocytopenia in dogs. Platelet counts started to decline after two days of dosing with 30 mg/kg/day and continued to decrease to their lowest levels by 5-7 days. The loss in platelets was primarily of the small discoid subpopulation. In vitro studies have also indicated that MDL 19,660: does not spontaneously aggregate canine platelets and has moderate antiaggregating properties by inhibiting ADP-induced aggregation. The objectives of the present investigation of MDL 19,660 were to evaluate ultrastructurally long term effects on platelet internal architecture and changes in subpopulations of platelets and megakaryocytes.Nine male and nine female beagle dogs were divided equally into three groups and were administered orally 0, 15, or 30 mg/kg/day of MDL 19,660 for three months. Compared to a control platelet range of 353,000- 452,000/μl, a doserelated thrombocytopenia reached a maximum severity of an average of 135,000/μl for the 15 mg/kg/day dogs after two weeks and 81,000/μl for the 30 mg/kg/day dogs after one week.

Objectives School-age children with and without parent-reported listening difficulties (LiD) were compared on auditory processing, language, memory, and attention abilities. The objective was to extend what is known so far in the literature about children with LiD by using multiple measures and selective novel measures across the above areas. Design Twenty-six children who were reported by their parents as having LiD and 26 age-matched typically developing children completed clinical tests of auditory processing and multiple measures of language, attention, and memory. All children had normal-range pure-tone hearing thresholds bilaterally. Group differences were examined. Results In addition to significantly poorer speech-perception-in-noise scores, children with LiD had reduced speed and accuracy of word retrieval from long-term memory, poorer short-term memory, sentence recall, and inferencing ability. Statistically significant group differences were of moderate effect size; however, standard test scores of children with LiD were not clinically poor. No statistically significant group differences were observed in attention, working memory capacity, vocabulary, and nonverbal IQ. Conclusions Mild signal-to-noise ratio loss, as reflected by the group mean of children with LiD, supported the children's functional listening problems. In addition, children's relative weakness in select areas of language performance, short-term memory, and long-term memory lexical retrieval speed and accuracy added to previous research on evidence-based areas that need to be evaluated in children with LiD who almost always have heterogenous profiles. Importantly, the functional difficulties faced by children with LiD in relation to their test results indicated, to some extent, that commonly used assessments may not be adequately capturing the children's listening challenges.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.
