“…Choosing a particular sample number was arbitrary as the actual population size was high (Cochran, 1977). The research budget, time, and quality were also considered in drawing the sample size (Lynn, 2016). A hundred sampled farmers were questioned utilizing a pre-tested interview schedule in October 2019 to collect data.…”

Determinants of training needs of the tilapia (Oreochromis sp.) fish farmers: an empirical study from a selected area in Bangladesh

Capacity building of fish farmers is inevitable for profitable fish farming. This research was undertaken primarily to identify the factors influencing the training requirements of tilapia fish farmers and to assess the level of training required for optimal farm management. Thus, the research was conducted in Phulpur Upazila (sub-district) under the Mymensingh district of Bangladesh. Face-to-face interviews were conducted with 100 randomly selected tilapia fish farmers using a pre-tested questionnaire. The training needs of tilapia fish farmers were measured using a four-point rating scale. The overwhelming majority (99%) of the respondents reported high training needs. Determination of mono-sex tilapia, a non-probiotic and probiotic fish production, and production techniques of mono-sex tilapia were identified as significant areas of training needs. Linear multiple regressions confirmed that level of education, experience in fish farming, training received, extension media contact and social mobility were the statistically significant determinants (P0.05) of the training needs for the tilapia fish farmers. The high cost of fish feed, unavailability of extension service, and high fertilizer costs were identified as the major problems faced by the respondents. Respective authorities, especially the Department of Fisheries (DoF), should emphasize initiating capacity-building programs for the farmers, considering the identified training needs and problems. In addition, providing training, ensuring the availability of credits at low-interest rate, supply inputs for tilapia culture for improving tilapia fish farming could facilitate the farmers.

“…Participating EIs were randomly selected from the study population using proportionate stratified sampling to guarantee that the sample reflected the structure of the population (see e.g. Lynn, 2016). The research questionnaire was sent to the sampled EI’s principal or school leader, who in turn was asked to distribute it to the staff.…”

Over the last two decades, the prevention of violent radicalisation, extremism and terrorism has become a major policy issue in Europe, and educational institutions’ central role in it has become widely acknowledged. However, what has rarely been addressed is that living in today’s media-centred world, in which terrorism receives much dramatic attention, news about violent extremist attacks reach every student and can significantly impact their emotions, beliefs, attitudes and feelings of safety. Since little attention has been given to how educators have addressed issues of violent radicalisation, extremism and terrorism with their students, this study relies on data-driven content analysis to investigate Finnish educators’ experiences regarding two issues in particular: first, what kind of themes associated with violent radicalisation, extremism and terrorism have been brought up in classroom discussions? Second, what provided the impetus for these discussions? The discussions in educational institutions dealt with the motives behind ideologically motivated violence, extreme ideologies, security concerns, immigration and ethical considerations. Recent violent attacks, curriculum content, students’ experiences and jokes requiring educators’ intervention provided the impetus for such discussions. The study findings are important for developing educational approaches to address violent radicalisation, extremism and terrorism-related issues in a pedagogically and ethically sustainable manner and to create ‘safe spaces’ for the discussions.

“…Email-diarists (see Table 1) were invited to take part using non-probability sampling, which has benefits of cost, ease of administration and accessibility (Lynn, 2002). Non-probability sampling is a practical method of recruiting participants by asking readily available respondents to participate.…”

The global research community has identified that, as the population becomes ever more mobile, and society 24/7-oriented, data collection methods that reflect the day-to-day experiences of its participants need to be developed. This paper reviews the success and issues of using a solicited emaildiary, developed to investigate the impact on commuters of London hosting the 2012 Olympic Games. Research on the effectiveness of diaries as a method of data collection is limited, whilst there appears to be no analysis using email as a method of soliciting diary responses. The paper identifies the research opportunities for an emaildiary and the solutions it provides to a number of the problems and limitations experienced with a traditional pen-and-paper diary.
