Performance success and positive development are goals of youth sport coaching that need not but often do find themselves in conflict with each other, yet there is a dearth of research that has inquired into the tensions between these 2 goals for sport coaches. Adopting an autoethnographic research design, this study explored the first author’s coaching experiences with a focus on his attempts to facilitate players’ personal development and the team’s performance success in a Canadian elite minor ice hockey context. Framed in a positive-youth-development approach, the first author’s philosophy and behaviors were informed by key tenants of achievement goal theory and self-determination theory. Three key areas were problematized: pursuing personal development and performance success, creating a task-oriented environment, and implementing autonomy-supportive behaviors. Practical implications for elite youth coaches and coach educations programs are discussed.

For 12 externally scoring college women, marginally significant correlations of EMG recordings with self-estimates of success in tensing forearm muscles (–.50) and with success in relaxing these muscles (–.54) were obtained. Similar correlations for 12 internally scoring women were much smaller. Analysis of variance of means had indicated no differences in ability of these groups to control muscles of the forearm.

The main aim of this research was to determine to which degree the system of variables used to evaluate specific motor skills correlated with the system of variables used to evaluate successful performance in football play. The study was conducted on a sample of 170 senior football players. There were 16 predictor variables to assess specific motor skills and eight criterion variables to assess successful performance. A canonical correlation analysis was applied in the statistical procedure to determine the relationships (correlations) between these spaces. Correlations were established between the investigated spaces with four pairs of canonical factors, and it has been shown that situational motor skills have high correlations with performance success in the game of football (Can R.=0.71, on average). It is indicated that the participants whose performance in football play was more successful also had better situational motor skills and that the mechanism for structuring movement is shown to be of great importance for the successful performance of tactical and technical elements in football players.

PurposeThe purpose of this paper is to explore why some firms succeed while others flounder or fail to implement quality improvement programmes. It synthesises self-efficacy literature to propose a model of self-efficacy’s role in affecting implementation success of quality improvement programmes in organisations.Design/methodology/approachA review of scholarly articles on the topics of self-efficacy and quality initiatives brings to light self-efficacy’s role in successful quality programme implementation. When considered in the context of organisation barriers, it can lead to organisational success.FindingsIt is determined that quality training programmes play an important role in affecting existing efficacies and leading to “quality self-efficacy” in employees. The proposed model and related propositions suggest that right approaches of implementing quality training among certain types of employees and/or organisations can promote teamwork to achieve performance success.Research limitations/implicationsMoving forward, the proposed model should be empirically tested to improve our understanding of quality self-efficacy construct and its role in aiding organisational success. Furthermore, it would offer guidelines for the implementation of quality programmes in the most optimal way.Practical implicationsIn applying theories on self-efficacy, motivation, empowerment, and quality training, the authors posit that existing efficacy and quality self-efficacy are crucial for quality implementation efforts to overcome organisational barriers and lead to effective teamwork and performance success.Social implicationsThe authors postulate that deciding factors for organisational success originate from employees themselves as existing efficacies. Even though employees can foster quality self-efficacy through the implementation of quality improvement initiatives, existing self-efficacy, and organisation barriers will be moderating forces on eventual effectiveness of quality self-efficacy, teamwork, and organisational performance.Originality/valueThe model and related propositions, linking self- and collective efficacies to quality training, teamwork, and quality performance, offered in this paper will prove useful for organisational decision-makers in selecting quality programmes for implementation in organisation to achieve performance success.

The Motivation Rating Scale was administered to 238 subjects. Respondents scoring at the extremes ( N = 40 in each) for the subscale of mental roughness were then tested in a choice RT task under conditions of success or failure. The experimental design consisted of a 2 (high, low mental roughness) × 2 (success, failure) factorial. There were no differences between groups, between success levels, or in the interaction of groups × levels.

It has repeatedly been show that with conventional electron microscopes very fine electron probes can be produced, therefore allowing various micro-techniques such as micro recording, X-ray microanalysis and convergent beam diffraction. In this paper the function and performance of an SIEMENS ELMISKOP 101 used as a scanning transmission microscope (STEM) is described. This mode of operation has some advantages over the conventional transmission microscopy (CTEM) especially for the observation of thick specimen, in spite of somewhat longer image recording times.Fig.1 shows schematically the ray path and the additional electronics of an ELMISKOP 101 working as a STEM. With a point-cathode, and using condensor I and the objective lens as a demagnifying system, an electron probe with a half-width ob about 25 Å and a typical current of 5.10-11 amp at 100 kV can be obtained in the back focal plane of the objective lens.
