Back to the Future – in support of a renewed emphasis on generic agility training within sports-specific developmental pathways

Perhaps as a consequence of increased specialism in training and support, the focus on engendering and maintaining agility as a generic quality has diminished within many contemporary sports performance programmes. Reflecting this, we outline a rationale suggesting that such a decreased focus represents an oversight which may be detrimental to maximising the potential of performers. We present an evidence-based argument that both generic and specific elements of agility performance should be consistently emphasised within long-term performance-training programmes. We contend that prematurely early specialisation in athlete development models can diminish focus on generic movement skill development with a subsequent detriment in adult performance. Especially when this is coupled with poor primary physical education and limited movement experiences. More speculatively, we propose that generic agility can play a role in operationalising movement development through facilitating skill transfer: thereby enabling the learning of new skills, reduce incidence of injury and facilitating re-learning of old skills during rehabilitation and Return-to-Play processes.     

Gamma heavy chain disease in a patient with rheumatoid arthritis – a laboratory evaluation

Introduction:

Heavy chain diseases (HCD) are neoplastic proliferations of B cells which secrete truncated immunoglobulin heavy chains without associated light chains. Being rare and probably underdiagnosed diseases the aim of this report is to show an additional case of gamma heavy chain disease in a 48 year old female patient with rheumatoid arthritis focusing on the laboratory presentation.

Materials and methods:

Laboratory work-up included agarose gel electrophoresis (AGE), capillary zone electrophoresis (CZE), immunofixation and nephelometrically determined immunoglobulin and immunoglobulin subclasses of the patient’s serum. Urine samples were also subjected to immunofixation and to a SDS-PAGE with consecutive immunoblot.

Results:

Nephelometrically measured elevated IgG concentrations were noted in combination with a decreased gamma globulin region and an increased beta globulin region on AGE. A definite monoclonal spike was not identified on AGE but at least suspected on CZE; finally serum and urine immunofixation demonstrated a monoclonal gamma heavy chain devoid of any corresponding light chains confirming the diagnosis of HCD. Analysis of the gamma heavy chain (HC) with means of SDS-PAGE revealed proteins of 40 kD and 80 kD most likely presenting a truncated HC in its monomeric and dimeric form and possibly leading to the failure of IgG-subclass typing with the applied IgG subclass antisera.

Conclusion:

This case report illustrates a new case of gamma HCD demonstrating variable laboratory manifestations and therefore the need for heightened awareness concerning this disease when confronted with abnormal and discrepant protein profiles in routinely applied laboratory tests.     

Task Characteristics and Learning Potentials—Empirical Results of Three Diary Studies on Workplace Learning

Most learning in the workplace occurs while pursuing working rather than learning goals. The studies at hand aimed to identify task characteristics that foster learning in the workplace. Task characteristics are supposed to exert a major effect on the learning potential. However, the fact that learning is more often than not a rather unconscious by-product of working poses methodological challenges because respondents might not be capable of accurately recalling daily work experiences. Diaries were applied in order to bring measurement closer to the processes. Three diary studies were conducted in the field of office work within vocational education and training, with trainees requested to record particular work tasks several times a day. Each diary record, i.e., each work task, required a rating of ten standardized items relating to task characteristics including the perceived learning potential of the present task. Eighteen trainees aiming to become retail salespersons recorded 488 work tasks, 10 trainees aiming to become bank clerks recorded 1,113 work tasks, and 20 trainees aiming to become industrial clerks recorded 573 work tasks. The aim of these studies was to explain the variance in the perceived learning potentials from further task characteristics using regression analyses. The extent of the explained variance ranged from 46.6 % in study 1 to 77.8 % in study 3. Interestingness, novelty, assistance from others, and feedback turned out to be the best predictors, whereas scope of action even showed negative influences. Practical implications for workplace learning as well as methodological recommendations for using diary methods in the workplace are discussed.     

Guidance in inquiry-based instruction – an attempt to disentangle a manifold construct

Inquiry-based instruction is an important teaching strategy in science education that can be implemented to achieve different learning goals (e.g. the learning of science content or of inquiry skills and strategies). Inquiry-based instruction is often combined with guidance attempting to assist students to effectively engage in inquiry activities and, through this engagement, reach the intended goals. In recent research, the type and amount of guidance needed to foster student’s learninghas received considerable attention. One challenge in interpreting the results of this line of research is the manifold meanings of the term ‘guidance’ and its implementation in inquiry-based instruction. Moreover, the effectiveness of a particular type and amount of guidance may also depend on the learning goal that is to be achieved. In this paper, we draw on existing research and theoretical considerations in attempting to disentangle three major dimensions in which the implementation of guidance may vary: (a) the degree of autonomy, (b) the degree of conceptual information, and (c) the cognitive domain of guidance. We discuss how these dimensions can be used to capture and systemise fidings of existing studies as well as to infer desiderata for further research on the role of guidance in inquiry-based instruction.     

Exposure to bullying,reactions and psychological adjustment of secondary school students

A sample of 575 secondary school students aged 11–15 years was administered a checklist on experiences of bullying, then divided into groups of victims, witnesses and not exposed, and by gender. Participants completed the Strengths and Difficulties Questionnaire on psychosocial adjustment. Victims and witnesses completed another questionnaire on the extent to which they would endorse retaliation/vengeance and avoidance towards the perpetrator. Girls reported being victimised significantly more than boys. Amongst victims, boys scored higher than girls on desire for retaliation/vengeance and on externalising behaviours; girls scored higher on internalising behaviour. Experience of bullying victimisation, rather than merely witnessing it or not being exposed to it, was associated with internalising behaviours for both boys and girls. These measures of psychosocial adjustment were associated with the desire for retaliation/vengeance. Implications are discussed of the links between gender, exposure to bullying, reactions and psychosocial adjustment of secondary school children.
