Peer bullying,self-serving cognitive distortions and school moral climate perception in Spanish and Dutch secondary school students / Acoso escolar,distorsiones cognitivas en beneficio propio y percepción del clima moral escolar en estudiantes de secundaria de España y Holanda

Students’ role in traditional bullying and cyberbullying was investigated in relation to self-serving cognitive distortions (SSCD), perception of school moral climate and bullying observation. Participants were secondary school students from Spain (n = 568; 286 girls) and the Netherlands (n = 421; 223 girls). The results demonstrated that in both country samples, bullies and bully-victims had higher levels of SSCD. Both Spanish and Dutch students who were directly involved in traditional bullying situations showed more negative perceptions of the school moral climate. In cyberbullying situations, bystanders scored higher on school moral climate perception than bullies and bully-victims. Furthermore, school moral climate perception was negatively associated with traditional bullying observation in the group of victims, and with cyberbullying observation in the case of victims and bystanders. The present findings suggest that future research should focus on the cause-effect relations of these factors, which could include measuring the effects on bullying prevalence of an intervention aimed at SSCD reduction in bullies and bystanders and the improvement of the school moral climate.     

Experimental evidence for diagramming benefits in science writing

Arguing for the need for a scientific research study (i.e. writing an introduction to a research paper) poses significant challenges for students. When faced with these challenges, students often generate overly safe replications (i.e. fail to find and include opposition to their hypothesis) or in contrast include no strong support for their hypothesis (i.e. relevant, valid evidence). How can we support novice scientists in generating and defending high quality hypotheses? A long history of research supports the affordances provided by structured representations of complex information. More recently, argument diagramming has gained traction in instruction for philosophy, social studies, and law. However, its effectiveness for supporting students in science is relatively untested. The purpose of the current study was to test the effectiveness of a simple argument diagram optimized for supporting students’ research writing in psychology. Two groups of undergraduate students in research methods lab courses were randomly assigned to diagramming support or no support. In the research papers, those given diagramming support were more likely to argue for an appropriately ‘risky’ hypothesis and wrote more about the relevance and validity of cited studies. Some of these gains show signs of transfer to a second paper written later in the course that did not require use of the diagramming tool.     

On the Correspondence between the Latent Growth Curve and Latent Change Score Models

There has been a great deal of work in the literature on the equivalence between the mixed-effects modeling and structural equation modeling (SEM) frameworks in specifying growth models (Willett &; Sayer, 1994). However, there has been little work on the correspondence between the latent growth curve model (LGM) and the latent change score model (see Grimm, Zhang, Hamagami, &; Mazzocco, 2013 Grimm, K. J., Zhang, Z., Hamagami, F., &; Mazzocco, M. M. (2013). Modeling nonlinear change via latent change and latent acceleration frameworks: Examining velocity and acceleration of growth trajectories. Multivariate Behavioral Research, 48, 117–143.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). We demonstrate that four popular variants of the latent change score model – the no change, constant change, proportional change, and dual change models – have LGM equivalents. We provide equations that allow the translation of parameters from one approach to the other and vice versa. We then illustrate this equivalence using mathematics achievement data from the National Longitudinal Survey of Youth.     

Territorial behavior of laboratory rats under conditions of peripheral anosmia

Two experiments investigated the influence of peripheral anosmia with zinc sulfate solution on aggressive and nonaggressive behaviors of rats in the colony intrusion paradigm. Experiment I was a replication of a previous observation that anosmic intruders arenot attacked by resident males. No significant differences were found in aggressive response to normal or anosmic intruders. Experiment II tested colony residents under normal and anosmic conditions for aggressive and nonaggressive response to intruders. The results were in agreement with previous reports that anosmia abolishes differential responding between males and females as well as all aggressive acts normally directed against unfamiliar males.     

African Americans’ Perception of Mental Health Professions

This study explored African-Americans perceptions of various mental health professions through the ranking of confidence levels across five case vignettes of varying psychiatric severity. Results indicated that African-Americans viewed psychologists and doctoral level licensed professional counselors with similar levels of confidence and ranked doctoral level licensed professional counselors above masters level counselors in every case example. Congruent with previous studies, the African American sample was confident in counselors ability to treat less severe cases and less confident in their ability to treat more severe cases.     

Effects of a combined inversion and plantarflexion surface on knee and hip kinematics during landing

Although landing in a plantarflexion and inversion position is a well-known characteristic of lateral ankle sprains, the associated kinematics of the knee and hip is largely unknown. Therefore, the purpose of this study was to examine the changes in knee and hip kinematics during landings on an altered landing surface of combined plantarflexion and inversion. Participants performed five drop landings from 30 cm onto a trapdoor platform in three different conditions: flat landing surface, 25° inversion, or a combined 25° plantarflexion and 25° inversion. Kinematic data were collected using a seven camera motion capture system. A 2 × 3 (leg × surface) repeated measures ANOVA was used for statistical analysis. The combined surface showed decreased knee and hip flexion range of motion (ROM) and increased knee abduction ROM (p < 0.05). The altered landing surface creates a stiff landing pattern where reductions in sagittal plane motion are transferred to the frontal plane, resulting in increased knee abduction. A stiff landing pattern is frequently related to increased risk of anterior cruciate ligament injury. It may be beneficial for athletes at risk to train for alternate methods of increasing their sagittal plane motion of the knee and hip with active knee or trunk flexion.     

Further evidence for the efficacy of an evidence-based,small group,literacy intervention program for young struggling readers

Abstract

An earlier series of pilot studies and small-scale experimental studies had previously provided some evidence for the efficacy of a small group early literacy intervention program for young struggling readers. The present paper provides further evidence for efficacy based on a much larger sample of young, socially disadvantaged, at-risk readers. The participants comprised 14 successive intakes of Year 1 and Year 2 students into small group remedial literacy intervention programs hosted by two charitably run tutorial centres. In each semester, over the years 2005–2011, eight students (on average) attended each centre for one hour, for four days per week, for 15 weeks. Pre- and post-test assessment data on eight measures of early literacy performance were available on up to 194 students who completed the program. Substantial and statistically significant gains were evident on all literacy measures with large effect sizes. These results provide further evidence for the efficacy of the small group literacy intervention program.     

New and rare lignicolous hyphomycetes from Zhejiang Province, China

Sporidesmiopsis zhejiangensis sp. nov. and Spadicoides americana were found on submerged wood from streams in Zhejiang Province, China. Sporidesmiopsis zhejiangensis is characterized by obclavate to fusiform, 5-6-distoseptate, versicolorous, verruculose conidia with an apical mucilaginous sheath. Spadicoides americana is a new record to China. These taxa are described and illustrated, and morphological differences between these species and their similar species were summarized.     

Effects of Short-Term Training On Residence Hall Assistants

Inasmuch as undergraduate residence hall assistants are being called upon more frequently to counsel students in social-personal problems and little training specific to this function has been given in the past, there is a need to develop an effective but brief training program leading to increased counseling effectiveness. Six hours of specialized training which focused on counselor accurate empathy enabled eight randomly chosen undergraduate resident assistants to increase their levels of accurate empathy significantly higher than a matched control group which received no training. In addition, the experimental Ss also demonstrated somewhat higher levels of counselor warmth.
