ABSTRACT The study sought to ascertain the adverse effects of consanguinity among Muslim parents of Aligarh city located in western Uttar Pradesh in India. More than 478 families were visited and data were collected from only 100 of them being inbred to varying degrees of consanguinity. It was found that increasing degree of consanguinity decreases fertility (R2 = 0.2671, r = -0.1568), but increases mortality (R2 = 0.3161, r = 0.5622). Selection intensity (R2 = 0.1734, r = 0.4164) and secondary sex ratio (R2 = 0.3757, r = 0.6129) also go up as the degree of consanguinity increases. However, the genomic basis of Runs of Homozygosity (ROH) is a more accurate method of calculating homozygosity. Next Generation Sequencing may help better understand ROH and their utility as a tool for inbreeding detection. To avoid the inbreeding load, there is a need to raise public awareness of reproductive health and the potential negative effects of consanguinity.
本研究旨在确定位于印度北方邦西部的阿里加尔市穆斯林父母的血缘关系的不利影响。研究人员访问了478个家庭,仅收集了其中100个不同程度近亲繁殖的家庭的数据。结果表明,亲缘关系越高,生育力越低(R2 = 0.2671, r = -0.1568),死亡率越高(R2 = 0.3161, r = 0.5622)。选择强度(R2 = 0.1734, r = 0.4164)和第二性比(R2 = 0.3757, r = 0.6129)也随亲缘关系的增加而增加。然而,纯合子的基因组基础(run of Homozygosity, ROH)是一种更准确的纯合子计算方法。下一代测序可能有助于更好地了解ROH及其作为近交检测工具的用途。为了避免近亲繁殖负担,有必要提高公众对生殖健康和近亲关系潜在负面影响的认识。

Joint Forest Management (JFM) is a programme that aims to manage the forests of India and to socio-economically develop the forest-fringe communities. A study on JFM was conducted in some forest-fringe villages of Jungle Mahals region of West Bengal. The main objective of the study was to see how JFM is functioning at present in those villages. It is revealed that the local forest department encourages the villagers to use, manage, protect and regulate the forest and its products. However, the villagers have some unfulfilled demands with the forest department. Furthermore, they cooperate with each other within the village but also are engaged in conflict with neighbouring villagers on the matter of the protection of forest and to access its resources. The paper suggests that the local forest department should negotiate with the local communities to resolve such conflicts and to make the JFM programme work more efficiently.
联合森林管理(JFM)是一项旨在管理印度森林并在社会经济上发展森林边缘社区的计划。对西孟加拉邦Jungle Mahals地区的一些森林边缘村庄进行了JFM研究。该研究的主要目的是了解JFM目前在这些村庄的运作情况。据透露,当地林业部门鼓励村民使用、管理、保护和规范森林及其产品。然而,村民们对林业部门有一些未满足的要求。此外,他们在村庄内相互合作,但也在保护森林和获取森林资源的问题上与邻近村民发生冲突。该文件建议,当地林业部门应与当地社区协商解决此类冲突,并使JFM计划更有效地运作。

Technical Vocational Education and Training (TVET) in South Africa has undergone major institutional, structural and curricular changes over the last twenty-seven years. At the centre of these changes lie skills mismatch and poor quality of graduates who have gone through Work Based Education (WBE) experience. This study was conducted on two campuses of one of the public TVET colleges in northern KwaZulu-Natal Province of South Africa. This mixed-method study used purposive sampling to identify the sample size of 21 participants, which comprised campus managers, senior lecturers and WBE champions. The findings revealed that the college management is failing to give necessary support to the implementers on the ground to carry out the WBE programme. Findings also revealed that the college management seems not to fully comprehend their role in enforcing compliance with the regulation guiding the WBE implementation. The need to strengthen ties with existing host employers and to recruit new host employers to address a serious shortage in graduate placement is evident. The study recommends that a clear vision for the implementation of WBE be prioritised and communicated to all stakeholders for effective implementation of the programme.
在过去的27年里,南非的职业技术教育和培训(TVET)经历了重大的体制、结构和课程变化。这些变化的核心是技能不匹配和接受过以工作为基础的教育(WBE)的毕业生质量差。这项研究是在南非夸祖鲁-纳塔尔省北部一所公立职业技术教育学院的两个校区进行的。本研究采用有目的抽样的方法,确定了21名参与者的样本量,这些参与者包括校园管理人员、高级讲师和WBE冠军。调查结果显示,学院管理层未能为实施WBE计划的实施者提供必要的支持。调查结果还显示,学院管理层似乎没有完全理解他们在执行指导WBE实施的规定方面的作用。显然有必要加强与现有东道雇主的联系,并征聘新的东道雇主,以解决毕业生安置严重短缺的问题。该研究建议,为有效实施该方案,应优先考虑实施WBE的明确愿景,并与所有利益攸关方进行沟通。

ABSTRACT The majority of the smallholder farmers mainly used clue implements. However, the extent to which they are determined to change such practice remains unknown. This paper investigates the smallholders’ willingness to pay (WTP) for tractor services, factors that affect the smallholders’ WTP for tractor services as well as factors that affect the amount of money the smallholder is willing to pay for tractor services. Multi-stage sampling technique was used to collect data from 280 respondents in the study area. The contingent valuation methodology was used to measure the smallholders’ WTP. Descriptive statistics and the double hurdle model were used to analyse the results. The majority of the smallholder farmers were willing to pay for tractor-use. Age, farm size and location affect the smallholder’ WTP for tractor services. Expenditure and location affect the amount of money willing to pay for tractor services by the smallholder. There is a prospective growth for hired tractor services business due to smallholders’ WTP. It was suggested that entrepreneurs should invest in the business of tractor hired services since the farmers were willing to pay for their services. More researchers should be done on how to sustain the smallholders’ demand and WTP for tractor services.
大多数小农主要使用线索农具。然而,他们决心在多大程度上改变这种做法仍不得而知。本文研究了小农购买拖拉机服务的支付意愿、影响小农购买拖拉机服务的支付意愿的因素以及影响小农购买拖拉机服务的支付意愿的因素。采用多阶段抽样技术,对研究地区的280名调查对象进行数据收集。采用条件价值评估方法对小农WTP进行测度。采用描述性统计和双栏模型对结果进行分析。大多数小农户愿意支付使用拖拉机的费用。年龄、农场规模和地点影响小农对拖拉机服务的WTP。费用和地点影响小农愿意为拖拉机服务支付的金额。由于小农的WTP,租用拖拉机服务业务有一个潜在的增长。有人建议企业家应该投资拖拉机租赁服务业务,因为农民愿意为他们的服务付费。应该对如何维持小农对拖拉机服务的需求和WTP进行更多的研究。

ABSTRACT The aim of the study was to assess the inter-generational differences in food and nutrient intake of three generations (grandparents, parents and children) living together. A cross-sectional survey assessed the food group and nutrient intake, changes in the intake over the years by using 24-hour dietary recall repeated over three days and focus group discussions. A total of 226 middle income families including 1,038 participants, grandparents (n=302), parents (n=423) and children (n=313) completed the diet survey. Focus group discussions with different generations explored the dietary transition over a period of time and the generation(s) responsible for menu related decisions. Children had significantly higher intake of cereals, other vegetables, sugars and fats as compared to their parents and grandparents (p<0.001) and highest mean percent adequacy of energy, protein and calcium (p<0.001). Information generated can be used to understand dynamics of food selection within a household and improve diet quality of all generations.
摘要本研究旨在评估共同生活的三代人(祖父母、父母和子女)在食物和营养摄入方面的代际差异。一项横断面调查通过使用三天内重复的24小时饮食回忆和焦点小组讨论,评估了食物组和营养素摄入量、多年来摄入量的变化。共有226个中等收入家庭完成了饮食调查,其中包括1038名参与者、祖父母(n=302)、父母(n=423)和子女(n=313)。与不同世代的焦点小组讨论探讨了一段时间内的饮食转变以及负责菜单相关决策的世代。与父母和祖父母相比,儿童的谷物、其他蔬菜、糖和脂肪摄入量明显更高(p<0.001),能量、蛋白质和钙的平均充足率最高(p<001)。所产生的信息可用于了解家庭内食物选择的动态,并提高各代人的饮食质量。

ABSTRACT The government of South Africa assisted beneficiaries with the establishment of projects to help alleviate poverty and create jobs in the country. Several projects were established amongst them: broiler production, vegetable production, and egg layer production. The focus of this study is on egg layer production. The objective of this study is to investigate the effect of COVID-19 on the marketing of eggs in the Vhembe district of Limpopo province, South Africa. In this study, the research design, which involved investigating the effect of COVID-19 on the marketing of eggs during the pandemic in the Vhembe district, using qualitative and explorative research was employed. The study employed focus group discussions where 7 members of the project from a total of 3 projects were interviewed. Egg layer projects have experienced a market loss of eggs during the past three months, structured interviews were also carried out with 1 extension officer in the college of agriculture who is responsible for conducting training and monitoring of such projects. The coded data were then analyzed using Statistical Packages for Social Sciences (SPSS version 22). The egg layer projects were facing the low market return of egg sales because of competition with commercial farmers who bring the stock to the local market. In conclusion, it is presumed that the results of this study would lead to informed decisions by the department of agriculture in terms of arranging markets and making sure that the commercial farmers do not compete with the projects in terms of prices of eggs.
摘要南非政府协助受益人建立项目,以帮助减轻贫困并在该国创造就业机会。其中建立了几个项目:肉鸡生产、蔬菜生产和蛋鸡生产。本研究的重点是蛋鸡生产。本研究的目的是调查新冠肺炎对南非林波波省Vhembe区鸡蛋营销的影响。在这项研究中,采用了定性和探索性研究的研究设计,包括调查新冠肺炎在Vhembe地区大流行期间对鸡蛋营销的影响。该研究采用了焦点小组讨论,共采访了3个项目中的7名成员。在过去的三个月里,蛋鸡项目经历了鸡蛋的市场损失,还对农业学院负责培训和监测此类项目的1名推广官员进行了结构化采访。然后使用社会科学统计软件包(SPSS版本22)对编码数据进行分析。蛋鸡项目面临着鸡蛋销售的低市场回报,因为与将库存推向当地市场的商业农民竞争。总之,据推测,这项研究的结果将导致农业部在安排市场和确保商业农民不会在鸡蛋价格方面与项目竞争方面做出明智的决定。

ABSTRACT Parasuicide is referred to as an apparent attempt at suicide without the actual intention of killing oneself. Its prevalence continues to increase at Brits District Hospital. The current study aimed to review the parasuicide cases presented at this hospital from 2013 to 2018. The hospital is located in Madibeng district, in the North-West Province of South Africa. The study results have painted a clear picture of parasuicide cases at Brits district hospital where the phenomenon was more often observed among young African females, who were single, unemployed, and with a secondary level of education.

摘要:自杀未遂是指在没有实际自杀意图的情况下进行的明显的自杀企图。它在英国地区医院的流行率继续上升。目前的研究旨在回顾2013年至2018年在该医院出现的准自杀病例。该医院位于南非西北省的马迪本区。研究结果清楚地描绘了英国地区医院的准自杀病例,在那里,这种现象更常见于单身、失业和中等教育水平的年轻非洲女性。对他们中的大多数人来说,这是第一次尝试,主要发生在1月和2月。药物过量是最常见的方法,关系问题仍然是促使这一尝试的主要原因。

ABSTRACT Due to the prevalence of poverty in Sub-Saharan African countries and Nigeria in particular, this paper seeks to investigate the influence of household endowments in reducing poverty among rural households in Ijebu-Jesa, Osun State. Using a multistage sampling approach, data was collected from 120 households and analysed using frequencies and percentages, Foster Greer and Thorbecke (FGT) index and logistic regression analysis. The result shows that the incidence of poverty among rural households is slightly pervasive (48.3%). It is also realised that gender, membership of the cooperative society, access to mobile, income, and household size are significant variables to explain the effect of the household endowment on poverty reduction. It is therefore recommended that the government should introduce policies aimed at facilitating the smooth establishment of cooperative associations in the study area and that tariffs on telecommunication should be subsidised to encourage more people to access and utilise mobile phones.
摘要由于撒哈拉以南非洲国家,特别是尼日利亚的贫困普遍存在,本文试图调查家庭捐赠对奥孙州Ijebu Jesa农村家庭减贫的影响。使用多阶段抽样方法,从120个家庭收集数据,并使用频率和百分比、Foster-Grier和Thorbecke(FGT)指数和逻辑回归分析进行分析。结果表明,农村家庭的贫困发生率略为普遍(48.3%)。性别、合作社成员、流动性、收入和家庭规模是解释家庭养老对减贫影响的重要变量。因此,建议政府出台政策,促进研究地区合作协会的顺利成立,并对电信资费进行补贴,以鼓励更多人使用和使用手机。
