In-group favouritism and out-group discrimination in naturally occurring groups.

We study in-group favouritism and out-group discrimination in a multiplayer dictator game in a naturally occuring group setting. An allocator divides a large sum of money among three groups of around 20 recipients each and also to themselves. The groups are supporters of two rival political movements in Thailand and politically neutral subjects. The non-rival out-group acts as a reference point and allows us to measure in-group favouritism and out-group discrimination. A treatment with artificial groups ser...

Group conquers efficacy: Preschoolers' imitation under conflict between minimal group membership and behavior efficacy.

Research has found that preschoolers' imitation demonstrates in-group bias and is guided by behavior efficacy. However, little is known about whether children's sensitivity to behavior efficacy affects their in-group imitation. This study aimed to investigate preschoolers' imitation tendency when group preference and behavior efficacy are in conflict. Participants were 4-year-old (N = 72) and 6-year-old (N = 72) preschoolers in China. They observed two demonstrators (one in-group and one out-group) pressing...

The 2,2-Dimethyl-2-(-nitrophenyl)acetyl (DMNPA) Group: A Novel Protecting Group in Carbohydrate Chemistry.

The 2,2-dimethyl-2-(-nitrophenyl)acetyl (DMNPA) group was introduced to synthetic carbohydrate chemistry as a protecting group (PG) for the first time. Benefiting from a unique chemical structure and novel deprotection conditions, the DMNPA group can be cleaved rapidly and mutually orthogonal to other PGs. Orchestrated application of the DMNPA group with other PGs led to the highly efficient synthesis of the glycan of thornasterside A.

Intermittent administration of low dose ketamine can shorten the course of electroconvulsive therapy for depression and reduce complications: A randomized controlled trial.

This study aimed to investigate the efficacy and safety of intermittent low-dose ketamine on improving the efficacy of ECT. Patients diagnosed with Major Depressive Disorder (MDD) (n = 134) were randomized into 3 groups: routine ECT group (group E, n = 45); repeated ketamine-assisted ECT group (group RK, n = 43), and intermittent ketamine-assisted ECT group (group IK, n = 46). Patients in group RK were given ketamine at the dose of 0.3 mg/kg for each ECT treatment, patients in group IK wer...

The impact of environmental factors on persons with dementia attending recreational groups.

The Comprehensive Process Model of Group Engagement posits that personal factors (e.g., cognitive function), stimulus factors (e.g., group activity content, group size) and environmental factors (e.g., light, noise) impact the response to group activities. This paper reports the impact of environmental and group characteristics on engagement, mood, and sleepiness of persons with dementia attending group activities.

Towards the elucidation of evolution of out-group aggression.

We focus on the implications of De Dreu and Gross's findings for the evolutionary perspective on out-group aggression and in-group cooperation. Although their experimental protocols are potentially useful in determining the origins of out-group aggression in humans, they so far provide inconclusive evidence only. We suggest ways of furthering our understanding of the connection between parochial cooperation and intergroup conflict.

Effect of vibration on the vestibular system in noisy and noise-free environments in heavy industry.

Chronic exposure to whole body vibration can affect the gastrointestinal system, the lumbar spine, the peripheral veins and the vestibulocochlear system. The aim of this study was to evaluate the effects of vibration on the vestibular system in noisy and noise-free environments using the video head impulse test (vHIT). A total of 138 employees were included in this study. Group 1 were exposed to vibration and noise. Group 2 only exposed to vibration, with no exposure to noise. Group 3 were not exposed to ...

Semen parameters and testicular dimensions in small breed dogs below ten-kilogram bodyweight.

Because of few available data on semen parameters in small breed dogs, the study aimed to analyse semen and measure testes of dogs < 10.0 kg bodyweight. Semen was collected from 41 fertile stud dogs which were divided based on bodyweight: group 1 < 5.0 kg, and group 2 between 5.1 and 10.0 kg.

We have extensively explored Au-Hg system under high pressure in the range of 0-300 GPa with and without spin-orbit coupling (SOC) inclusion. The variable-composition methodology has been used as employed in Universal Structure Predictor: Evolutionary Xtallograpgy (USPEX) in combination with Vienna Ab Initio Simulation Package (VASP). We have predicted several thermodynamically stable stoichiometric compounds of Au-Hg system, i.e. Au3Hg (space group 194, P63/mmc), AuHg (space group 62, Pnma), AuHg2 (space g...

Returning to home cage serves as an effective reward for maze learning in rats.

This study examined the effectiveness in rats of 'returning to home cage' as a reward for learning a Lashley III maze. Rats could return to their home cage directly (Direct HC group) or they could be removed manually by an experimenter from the maze's goal box (Indirect HC group). In the third group, hungry rats received a food reward in the goal box (Food group). The Direct HC group reliably learned the maze and its performance was very similar to that of the Food group. In contrast, performance by the Ind...

Emergent Invasive Group A Streptococcus dysgalactiae subsp. Equisimilis, United States, 2015-2018.

The term group A Streptococcus is considered synonymous for the species Streptococcus pyogenes. We describe an emergent invasive S. dysgalactiae subspecies equisimilis lineage that obtained the group A antigen through a single ancestral recombination event between a group C S. dysgalactiae subsp. equisimilis strain and group A S. pyogenes strain.

Spinopelvic parameters in degenerative spondylolisthesis.

The purpose of this study was to compare various sagittal spinopelvic parameters between patients with and without degenerative lumbar spondylolisthesis (DLS). A total of 165 patients who underwent surgery for low back and/or radicular pain were divided into two groups: those without DLS (non-DLS group; n = 85) and those with DLS (DLS group; n = 80). In all sagittal spinopelvic parameters, no significant difference was found between the non-DLS and DLS groups. The mean pelvic incidence (PI) value of the DLS...

Power struggles: when and why the benefits of power for individuals paradoxically harm groups.

Research on the dysfunctions of power for group interactions is covered in this review. While individuals generally benefit from possessing power, groups often are plagued by power struggles when one or more individuals within the group possess power, such as in groups with high intra-group power dispersion (e.g. a clear job title hierarchy or differences in salary levels) or a high average level of member power (e.g. management teams, all-star sports teams). In such groups with at least one powerful member...

Group bias in children's merit-based resource allocation.

From early in life, children show sensitivity to both merit and group membership. However, little research has examined how children react to the conflicting demands of allocating meritoriously and favoring in-groups during resource allocation over the course of their development. We compared how children aged 3-5 years and children aged 6-8 years allocated and reasoned about allocations to in-group and out-group members in a merit-based context. In Study 1, in four distribution tasks, children needed t...

Does group membership affect children's judgments of social transgressions?

Children judge in-group members more favorably than out-group members. They also judge moral transgressions as more serious and more worthy of punishment than conventional transgressions. Here we asked whether children's judgments of moral and conventional transgressions vary by the group membership of the transgressor (in-group, neutral, out-group, or self). In addition, we asked whether judgments of the transgressions would extend to the transgressors themselves, including cases in which the self was the ...

Ir(III)-Catalyzed Mono-Olefination of Aryl C-H Bonds Using -SCF as a Weak Directing Group.

The trifluoromethylthionyl group (-SCF) is an efficient weak directing group for Ir(III)-catalyzed aryl C-H olefination. Various trifluoromethylthioethers provide high levels of mono-olefination products in good to excellent yields under mild conditions with a 2,2'-bipyridine ligand or AgBF as an additive. Mechanistic studies indicate the C-H cleavage is the rate-determining step. The directing group ability of the -SCF group is benchmarked against several other weak directing groups by competition experime...

A Group Dynamics-Based Exercise Intervention to Improve Physical Activity Maintenance in Breast Cancer Survivors.

To maintain increases in physical activity (PA), interventions that implement group dynamics principles and strategies with the intent of enhancing group cohesion may be advantageous. This study examined group cohesion and PA following a group dynamics-based PA intervention among breast cancer survivors.

Engaging children and youth in research and evaluation using group concept mapping.

Group concept mapping is a systematic methodology that recognizes participants' expertise in their own experiences. In this approach, participants share their diverse knowledge and interpret the data generated by all group members. This approach uniquely blends quantitative and qualitative techniques to create illustrative, structured conceptualizations. In this article, we describe the steps in group concept mapping and report feedback on this method from 37 children and youth who participated in group con...

Three hundred and six patients about to receive AKS were consecutively enrolled in this randomized, controlled study and randomly allocated into three groups: very early analgesia (VEA) group, early analgesia (EA) group, and postoperative analgesia (PA) group. Pain v...

Advantaged- and disadvantaged-group members have motivations similar to those of defenders and attackers, but their psychological characteristics are fundamentally different.

Modern societies are characterized by group-based hierarchies. Similar to attackers, disadvantaged-group members wish to change the status quo; like defenders, advantaged-group members wish to protect it. However, the psychological arrays that are typical of disadvantaged- and advantaged-group members are opposite to those of attackers and defenders - suggesting that the Attacker-Defender Game does not capture the dynamics between advantaged and disadvantaged groups.

Correlation of Preoperative Biomarkers with Severity of Adhesion in Endometriosis.

This study was undertaken to evaluate the preoperative correlation of serum markers and pelvic adhesions in endometriosis patients, and to explore their clinical value for prediction. Preoperative basic serum laboratory test and CA 125 were analyzed, and the adhesion score calculated. The group with less than 28 points was defined as a mild adhesion group, and a score of 28 or more as a severe adhesion group. CA 125 was significantly higher in severe adhesion group than mild adhesion group. CA 125, size of ...
