In the present study, a test was developed to measure the knowledge level of dairy farmers about scientific dairy farming. A preliminary set of 87 knowledge items was initially administered to 60 randomly selected dairy farmers for item analysis. The difficulty index and discrimination index was found out, and the items with difficulty index ranging from 30 to 80 and the discrimination index ranging from 0.30 to 0.55 were included in the final format of the knowledge test. A total of 48 items which fulfilled both the criteria were selected for the final format of knowledge test. Reliability of the test through split half method was found out to be 0.386 and the coefficient of correlation value by the test-retest method was 0.452, which was found to be significant at 1% level of significance. Hence, the knowledge test constructed was highly stable, reliable and validated for measuring what it intends to.

Difficulty Index

This study, conducted in the Republic of Korea, analyzed nursing faculty members’ knowledge of and attitudes toward research ethics according to their characteristics and the institutional environment. A survey was conducted from April 24 to July 23, 2017. The participants were 210 nursing professors from 57 universities in Korea. The survey questionnaire gathered information on participants’ characteristics, their knowledge of and attitudes toward research ethics, and their perceived training needs. A relatively low difficulty index was found for knowledge items dealing with conflicts of interest (0.66), copyright (0.65), and plagiarism and duplicate publications (0.17) than for the other six items. Of the 12 items assessing attitudes toward research ethics, use of a plagiarism-checking program and reviewing manuscripts from members of one’s own research group had the lowest scores. The knowledge level of participants whose institutions provided a plagiarism-checking program was higher than those whose institutions did not. Former group also showed better attitudes toward research ethics. High-priority training needs were obtaining institutional review board (IRB) approval, writing informed consent forms, and obtaining informed consent for studies on children and pregnant women. A more intensive training program for nursing faculty is required on specific topics, including conflicts of interest, copyright, plagiarism, duplicate publications, IRB approval, and informed consent. Furthermore, all nursing institutions in Korea should provide a plagiarism-checking program to faculty members.

Background: Multiple choice questions (MCQs) are a common method of assessment of medical students. The quality of MCQs is determined by three parameters such as difficulty index (DIF I), discrimination index (DI), and Distractor efficiency (DE). Item analysis is a valuable yet relatively simple procedure, performed after the examination that provides information regarding the reliability and validity of a test item. The objective of this study was to perform an item analysis of MCQs for testing their validity parameters.Methods: 50 items consisting of 150 distractors were selected from the formative exams. A correct response to an item was awarded one mark with no negative marking for incorrect response. Each item was analysed for three parameters such as DIF I, DI, and DE.Results: A total of 50 items consisting of 150 Distractor s were analysed. DIF I of 31 (62%) items were in the acceptable range (DIF I= 30-70%) and 30 had ‘good to excellent’ (DI >0.25). 10 (20%) items were too easy and 9 (18%) items were too difficult (DIF I <30%). There were 4 items with 6 non-functional Distractor s (NFDs), while the rest 46 items did not have any NFDs.Conclusions: Item analysis is a valuable tool as it helps us to retain the valuable MCQs and discard or modify the items which are not useful. It also helps in increasing our skills in test construction and identifies the specific areas of course content which need greater emphasis or clarity.

Multidimensional Constraints

Women, who try to enter the field of industry in either managerial or entrepreneurial role, are generally exposed to various constraints. Though the entrepreneurial process is the same for men and women, there are however, in practice, women have to confront many additional problems of varying dimensions and magnitudes, which prevent them from realizing their full potential as entrepreneurs. Women entrepreneurs experience multidimensional constraints. The governments at the centre and the states have established a number of specialized institutions to cater to the needs of women entrepreneurs but they still face many problems. At this juncture, the constraints faced by women entrepreneurs were studied as one of the objective. This objective was to ascertain the financial, production and labour constraints faced by women in their enterprise. To achieve the purpose of the study, 40 registered women entrepreneurs in Micro Small and Medium Enterprise (MSME) were identified in Coimbatore District of Tamil Nadu. Series of questions were asked through well structured interview schedule. Evidence in the paper shows that the most serious financial constraint faced by women was, that the entire loan was not given at a time (65.00%). In production and labour, most serious constraints faced by women entrepreneurs were labour management in various essential activities (92.5%). Methodology and design not clarified here. No recommendations The ex post - facto type of research was employed. Proportionate Random sample method” was adopted to select the respondents from the four Entrepreneurial Hubs. Women should attend training programs, seminars, workshop and conferences Related to develop professional competencies in managerial, leadership, marketing, financial, production process, profit planning, maintaining books of accounts and other skills.
