SOCIAL BEHAVIOUR DI PESANTREN SALAF

Salaf pesantren is an institution that is still strongly bound by old traditions. By inheriting and maintaincontinuity of Islamic tradition developed by scholars from time to time indefinite periodesasinya, has elementswhich include clerics, students, cottage / hostel, mosque, recitals of classical texts / yellow book, applyingthe method bandongan, sorogan, wetonan, principled firmly on Islamic education material. Pesantren Salafurgently need progress in science and technology. Pesantren Salaf there are many who “failed†to preserve itsown leadership weights, weak in preparing a “succession†Kyai guardians comparable with the foregoing, letalone exceeded. Answering the needs of the era, schools Salaf open formal educational institutions. Sensitivitypesantren Salaf against the phenomena that appear in the society is a social concern and reflexive owned evenare characteristic. So that the aspirations of the people making the boarding school received the developmentand advancement of science and technology. The real step taken is establishing formal educational institutionsfrom kindergarten through college. The character of a scholar is asceticism and totality. On the other hand,people still expect the efficacy of the function and role of pesantren Salaf like period once, without knowing thatit is actually what is expected it is experiencing overcast condition and shrinkage. Expenses are given the addedweight and more and more, but the ability to lift a boarding school in general was declining. Source overcastcondition and depreciation mainly boils down to the weight and quality of the “clerics who brought upâ€. Both interms of science, wisdom, exemplary, sincerity, and shelter to the people.Keywords : Social behavior, pesantren Sala

EFFECTS OF DIFFERENT WARM-UP TECHNIQUES ON DYNAMIC BALANCE AND MUSCULAR STRENGTH ON PLAYERS: A STUDY

Warm-up helps the individual to prepare themselves for the strenuous workout. Warm-up is generally executed prior participation in any physical activity or sports. Active warm-up includes low-intensity exercises, whereas passive warm-up includes external heat resources that are useful to enhance body temperature. The objective of the study was to compare the effect of active, passive and combined warm-up techniques on dynamic balance and muscular strength of the players belonging to hand dominated sports such as handball, volleyball, and basketball. To fulfill the objective 15 players of hand dominated sports were recruited as the sample further they were divided into 3 groups i.e. active, passive and combined comprising 5 players each on a random basis. The average chronological age, stature height, and body weight of the subjects were 26.5 ± 5.7 years, 172.4 ± 3.4 cm, and 68.7 ± 5.6 kg, respectively. For dynamic balance, the equilibrium management test was administered by stabilometer (Techno-Body Machine). The test was done with open and closed eyes, with two stability level i.e. 10 & 20. An isokinetic dynamometer (BIODEX) was used to measure muscle strength. The test was started as participant performed 5 repetitions of CON/CON at low speed of 60/60 0/sec. and by a high speed of 180/180 0/sec. Before taking data on dynamic balance and muscular strength, all 3 groups were given different warm-up techniques which technique was assign to their group. The obtained data were statistically analyzed by using IBM SPSS v.20 software. Descriptive statistic and one-way ANOVA were computed. The results revealed there is no significant difference in any warm-up method on muscular strength as well as on dynamic stability

A COMPARATIVE STUDY OF EXERCISE MOTIVATION BETWEEN MALE AND FEMALE UNDER 17 YEARS SOCCER PLAYERS

The purpose of the present research was to compare the level of exercise motivation of male and female soccer players. Secondary purpose of this work was to answer of the question “which gender needs what extend of exercise motivation to perform better in sports?” The method carried out in this study was quantitative in nature and based on the questionnaire study. Population of this research consisted on all male and female soccer players in Rakiraki Public High School, Kings Road, Fiji. Among the total population the sample consisted on 50 boys and 50 girls (all subjects were below 17 years of age). The Exercise Motivation Inventory developed by Markland and Hardy, (1993) was used to gauge the level of exercise motivation of both genders. Results of statistical analysis (t-test) showed that there was no significant difference between male and female players on their level of exercise motivation, but the mean value of female players was found considerably higher than the male players. This finding leads to conclude that both male and female under 17 years soccer players having same level of exercise motivation.  Article visualizations

MENTAL TOUGHNESS AS A DETERMINANT FACTOR OF PERFORMANCE IN TABLE TENNIS

The purpose of this study was to investigate the effect of mental toughness on the performance score of table tennis players. To work on this purpose a total of 24 table tennis players (male and female) were selected as the subjects purposively. The Mental Toughness Questionnaire developed by Goldberg (1995) was used to measure the level of mental toughness of the players. ANOVA and independent t-test was computed to find out the significant relationship. Level of significance was set at 0.05. The results indicate that- there is significant relationship exists for the handling pressure a sub-category of mental toughness among table tennis female and male players, further it was found that there is no significant difference exists between table tennis female and male players in the variables of concentration, mental rebounding, and winning attitude and/or other sub-categories of mental toughness. The comparison between female and male in this study has not shown any significant difference but as a means, the male players have greater mental toughness than their counterpart.   Article visualizations

PHYSICAL FITNESS VARIABLES REQUIRED FOR PRE-SERVICE TEACHERS

This study undertaken to identify which physical fitness variables are involved while pre-service primary teachers (PSPT) perform their teaching-learning activity. A qualitative research approach was adopted in this study. Ten classes of PSPT were observed during their internship program. During observations it was documented that PSPT were unknowingly engaged themselves in different physical movements such as- sit-ups, bending, squatting, sitting, standing, sitting on toes, hand raise, walking, dancing movements, and neck movements etc. All of these physical movements everyone performs on regular basis but with quite less frequency and intensity. Those who engaged in teaching-learning process have to do these movements in higher frequency and intensity as observed by the investigator. Consequences of increased frequency and intensity of these movements are physical and mental fatigue which subsequently hampers the performance of PSPT. As every movement is associated with different physical fitness variables, thus a matching exercise with consultation of experts was performed. The most dominant variables were identified as- strength endurance of legs, shoulders, back and calf; flexibility of hip, cervical, spine and shoulders; and coordination of leg & hand.  Article visualizations

Landlessness in Rural Areas of Pakistan and Policy Options: A Preliminary Investigation

The quantification of landlessness is a formidable task. Conceptual ambiguities involved in the classification of landlessness and data limitations compound the difficulties in the estimation. Landlessness, which is an elusive concept, tends to acquire interpretations which vary with the objectives, context and estimation procedures adopted in different research endeavours. The denotation and connotation of the concept of landlessness, the population of interest (or at risk) and the objectives of measurement therefore need to be spell out very clearly for a meaningful and policy-relevant exercise. Identification of the state of landlessness using the criterion of ownership and access to land, has often been made. While the 'ownership' may be clear in certain contexts, that of 'access' needs further explanations in terms of the nature, extent and type of access. A related question, is the demarcation of the population or its subset whose landlessness is to be estimated: are all the inhabitants of an area or the ones who primarily depend on land for their livelihood be regarded as the relevant population. The dependence on land needs to be further specified whether the person is engaged in agricultural operations as worker or not
