Hands are important tools for manual work. Although researchers have identified factors that influence the grip efforts of an entire hand, there appears to be limited research concerning the use of different pinch techniques and how they affect the performance of pinch effort. Therefore, the aim for this pilot study is to determine the effects of different pinch techniques on pinch effort. A total of 110 manual workers from a wooden pallet manufacturing firm participated in this study, which involved an experiment and survey to investigate the most preferred pinch technique applied on screw knobs. The techniques used were the 3-jaw chuck, pulp-2 and lateral pinch. A total of 6 screw knobs of different shapes and sizes were used. After the data were collected, descriptive and Cronbach's alpha reliability analyses were carried out. The results show that the preferred pinch technique for the small cylindrical knob, small sphere knob and all large knobs is the lateral pinch. However, the 3-jaw chuck pinch is preferred for the small 5-lobes knob. This study provides preliminary information for further research on pinch techniques and their influences on the pinching outcomes of individuals.

This study identified the readiness factors that may create challenges in the use of telemedicine among patients in northern Louisiana with cancer. To identify these readiness factors, the team of investigators developed 19 survey questions that were provided to the patients or to their caregivers. The team collected responses from 147 respondents from rural and urban residential backgrounds. These responses were used to identify the individuals’ readiness for utilising telemedicine through factor analysis, Cronbach’s alpha reliability test, analysis of variance and ordinary least squares regression. The analysis results indicated that the favourable factor (positive readiness item) had a mean value of 3.47, whereas the unfavourable factor (negative readiness item) had a mean value of 2.76. Cronbach’s alpha reliability test provided an alpha value of 0.79. Overall, our study indicated a positive attitude towards the use of telemedicine in northern Louisiana.

<p><em>Independent Sri Lanka has been making efforts ever since 1948 to expand the provision of educational opportunities to her citizenry. Several committees and commissions were set up for this purpose. There recommendations along with the deliberations at the higher levels of policy planning for the country have led to the introduction of several innovative practices in education. One such innovation is “distance education”. Conventional face-to-face education is teaching or teacher centered, while distance education is learning or learner centered. It is so because if education is to function as a means of social enlistment and democratization, it cannot but be learner centered. And again, if we accept education to be a life long activity, an activity that constantly engages learners in updating their information and skills, it has to be learner centered.</em></p><p><em>The objectives of the study were: identification of personal characteristics of the distance learners; investigation of the heterogeneity of the students; investigation of the salient trends between the success rates and the student personal and educational characteristics of Sri Lankan distance student population and Identification of the needs and aspirations of distance learners.</em></p><p><em>Therefore, a draft copy of a questionnaires were distributed to a pilot sample of 100 students selected at random from Degree programmes of 2012/2013 academic year. The responses of the student sample was obtained and served as a data source for the pilot study. The data set obtained from the pilot study was subjected to the Reliability analysis (Cronbach, 1951). The reliability coefficient, i.e., Cronbach’s alpha which indicates the suitability of the questionnaire for the purpose and the higher values (<em><em>Cronbach’s alpha</em> is more than </em>0.50) often considered as an acceptability of the questionnaire.

Background: Speech and Language Therapy is an established profession in many countries of the world but still very new in Bangladesh. There is no culturally appropriate adult assessment tool for assessing patient with Apraxia in Bangladesh and has no alternative tool in own language to assess and diagnose patient with apraxia. Objectives: The aim of the study was cultural adaptation of Apraxia Battery for assessing the patient with Apraxia. Methodology: A total of nineteen people diagnosed with apraxia of speech, within the age from 37 to 80 years, participated in this study. The investigator was used quantitative (item analysis, validity determination and reliability determination) and qualitative (observation and focus group discussion) method for the adaptation procedure. After observation and focus group discussion the investigator received concern from the panel of expert for conducting the pilot study. After find out the pilot study result the investigator conducted test and retest. The result was discussed changing forward translation, changing pilot study and test retest findings. The pilot study was examined in a sample of eight apraxia patients. The interval between five days the test and retest reliability was examined in a sample of eleven apraxia patients. Using the Cronbach’s alpha, examined the internal consistency and intra-class correlation for test retest reliability. Results: After modification of ABA-2 tool, the pilot study showed that the ABA-2 tool was in culturally appropriate in Bangladesh for apraxia patient. The test reliability for Diadochokinetic Rate, Increasing word length   (Part A), Increasing word length   (Part B), Limb Apraxia, Oral Apraxia, Latency Time for polysyllabic word, Utterance Time for polysyllabic word and Repeated Trials sub-tests appear to be satisfactory as researchers claim that Cronbach’s alpha coefficients ranging between .8143 and 0.9006 indicate good to excellent reliability. And the retest reliability for these subtests Cronbach’s alpha coefficients ranging between 0.7898 and 0.9095 indicate acceptable to excellent reliability. The intra-class consistency for all subtest of the test and retest was excellent (Cronbach’s alpha =0.9478 to 0.9917). Conclusion: This study suggests that valid assessment of apraxia patient using the ABA-2 assessment tool. The modified ABA-2 assessment tool is feasible for assessing the patient with apraxia in content of Bangladesh. The test retest result also showed that the ABA-2 assessment tool was reliable in culturally. ABA-2 is reliable and valid instrument for evaluating the patients with apraxia. This assessment tools also help Speech and Language Therapists to assess and diagnose the patient with apraxia.
