Biggs [2007] describes how understanding relationships between generations lies at the heart of society’s contemporary dilemmas yet in the social sciences, it remains to be a relatively under explored lens to understanding processes of change [Biggs, 2007, p. 695]. The following research gathered existing literature that discusses intergenerational relations in the domains of a) Sociology and b) Social Gerontology. The sociological tradition discusses processes of social change or how significant historical events shape the environment we age in while the Social Gerontological tradition examines social structures that organize activities across the life course. Using Suhair Inayatullah’s Causal Layered Analysis as a framework, the following research deconstructed a projected trend of rising demographic depende...

Subjects were recruited from Faculty of Physical Education for Men, Alexandria University, Egypt, with ages between 19 to 20 years old. The experimental group attended 16 sessions (8 for tennis, 8 for field hockey) over six weeks (40 minutes each) and used mental training exercises (relaxation, visualization and concentration-attention control) pertinent to the forehand, backhand in tennis and push pass, hit in field hockey. Two waves of measurements were conducted (before and after the completion of the intervention) with the use of motor assessment tests related to the sport of tennis and field hockey. Each student was evaluated regarding to his technique of forehand, backhand in tennis and push pass, hit in field hockey in order to examine the effectiveness of mental training. Questionnaires were also used to measure visualization and concentration-attention control. The results showed a highly significant improvement in learning forehand, backhand in tennis and push pass in field hockey. However, no statistical difference was found for the performance of the hit stroke in field hockey. In addition, the findings showed also a significant difference between the initial and the final measurement regarding to the ability of concentration and visualization by using questionnaires. The results revealed a value of 0.780 which indicates a good reliability of the tool. As a conclusion, a combination of mental and practical training promises the greatest improvement in performance and learning, because it involves all senses.

Patients and methods: Thirty patients were included in this study and had preoperative infantile esotropia with large angles (ie, 30 prism diopters [PD]). Patients were divided into Group A, which underwent bilateral medial rectus (BMR) recession and Group B, which underwent bilateral Y-split recession of medial recti muscles. All patients were subjected to complete ophthalmologic examination and met the criteria for inclusion in this study. The degrees of BMR recessions performed ranged from 6.0-7.5 mm. All operations were performed under general anesthesia. Follow-up visits were conducted at 1 and 2 weeks, and 1, 3, and 6 months postoperatively. Rates of reoperation for residual esotropia and consecutive exotropia were determined. Results: The patients' preoperative angles of deviation ranged from 30-80 PD. Group A consumed 57% less operative time than Group B. Immediately postoperatively, the Y-splitting technique showed satisfactory results (ie, orthotropic or residual angles 15 PD) in 73% of patients vs 67% only for the BMR recession patients. By the end of six months of follow up; 13% of the BMR technique patients vs 27% of the Y-splitting technique patients showed negative change of PD but without reoperation. Conclusion: Our results suggest that, although the Y-splitting technique is more difficult and time consuming, both procedures are effective and have shown comparable results for the correction of horizontal deviation 70 PD.
