Based on the survey data of 354 farming households, this paper, taking the national poverty county of Lingao County, Hainan Province for an example, examined the characteristics of rural poverty of the county. Moreover, this paper established the spatial lag model(SLM) from five dimensions, namely, status of the household head, household structure, health status, income composition and traffic accessibility, to analyze the main influencing factors of rural poverty according to the values of Moran's I and the diagnosis of spatial dependence of the OLS model. It is found that the poor farming households gathered mainly in five towns in the north and southwest of the county, and the rural poverty have the characteristics of low educational level of the heads, more minor children, high population of farming peasants, high incidence of disease and low proportion of household wage-equivalent income. The results also showed that the variables such as the number of minor children, the number of migrant worker, the number of farming peasants and the proportion of wage-equivalent income have significant effectiveness on rural poverty, while the status of the household head, health status and traffic accessibility have little influence. It is an important way to realize the goal of poverty alleviation by controlling the number of farmers' fertility, strengthening the vocational skills training of farmers, vigorously developing specialization and large-scale agriculture and increasing the employment opportunities of farmers.展开更多

METHODS: This was a retrospective, chart review, cohort study in a Canadian, tertiary care, academic, hospital-based endoscopy clinic. Patients included were: those undergoing esophagogastroduodenoscopy, colonoscopy or flexible sigmoidoscopy and patients who failed to appear were compared to a control group. The main outcome measure was a multivariate analysis of factors associated with truancy from scheduled endoscopic procedures. Factors analyzed included gender, age, waiting time, type of procedure, referring physician, distance to hospital, first or subsequent endoscopic procedure or encounter with gastroenterologist, and urgency of the procedure. RESULTS: Two hundred and thirty-four patients did not show up for their scheduled appointment. Compared to a control group, factors statistically significantly associated with truancy in the multivariate analysis were: non-urgent vs urgent procedure (OR 1.62, 95% CI 1.06, 2.450), referred by a specialist vs a family doctor (OR 2.76, 95% CI 1.31, 5.52) and office-based consult prior to endoscopy vs consult and endoscopic procedure during the same appointment (OR 2.24, 95% CI 1.33, 3.78). CONCLUSION: Identifying patients who are not scheduled for same-day consult and endoscopy, those referred by a specialist, and those with non-urgent referrals may help reduce patient truancy.展开更多

How and where did the children growing up without traditional family structure learn to be men? This study examines a specific group of children – young apprentices in medeival England – in order to reconstruct how fatherless sons learned the concept of masculinity. To further the question – did the separation of their natal fathers during their youth made boys less masculine? By examining the indentures, court records and various administrative records, this study demonstrates that, apprentices went through more masculine relationships than the children grew up with their fathers’ prescence, because masters wielded he supreme power which made them de facto “surrogate fathers”. This study also manisfests that apprenticeship was the extension of fatherhood, because it led apprentices to experience absolute subordination to their masters, reducing them to the position of “full-dependence” in their social communities.展开更多

Due to globalization and changes in the world, housing is no longer only a structure that provides sheltering but is also a factor that provides mutual interaction in formation of life style and quality. The elements such as the increase in the effect of consumption preferences and life style on selections, the changes in family structure, and urban structures also influence the residences used and housing preferences. The purpose of this study is to determine the general situation of housing preferences while taking into account the family life style in Turkey and at the same time to make an evaluation based on international publications.展开更多

This demographic change has some impact on the economic and social situation of the latter, in particular, the functioning of the family structure and solidarity between generations. The successive crises (food and financial) coupled with structural adjustment programs have in fact worsened the problems of the elderly, without having for compensation, provided the corresponding benefits for other age groups. This study contributes to the analysis of changes over time in the family support system, especially with regard to household's heads aged in Cameroon. To achieve this, the discussion turns around three questions: (1) what is the extent and nature of the ageing in Cameroon? (2) what are the demographic, economic, and social implications? and (3) what is the impact of economic and social change on intergenerational relationships? The data used come from the Population Census (1976, 1987, and 2005), and the Cameroonian Household Survey of 2007. The gradual deterioration of the support system for the family, especially due to modernization, and the current and future numbers of older should bring more policymakers to meet the specific needs of this group in Cameroon.展开更多

The rapid growth of the elderly population will inevitably bring about changes in the family structures, which leads to the inevitable development trend of the old-age pension institutions for the elderly. With the progress of the society, the needs of the elderly for the old-age pension are not only satisfied with their life care, but also with the spiritual needs. Based on the planning contents of the 13th Five-Year Plan for the elderly, on the basis of the Maslow's demand level theory, this paper analyzes the present status of the services of the institutions for the elderly to the elderly psychological health, and concludes that the needs of the emotions of the elderly, the needs of their self-esteem, the needs of their self-realization and their physiological needs of the elderly and their security needs are equally important.展开更多

The result of the model showed urban residents' annual disposable income and having meals out of home play the greatest effect on the consumption of aquatic products, followed by the number of retail chains stores; family structure plays a negative effect on the consumption of aquatic products. Also, the analysis shows not only the prices of the aquatic products as well as substitutes should be considered and also the quantity of the meals consumed by residents out of home and the number of retail chains stores should be used as important associated factors in studying the change trend of aquatic products consumption, and simultaneously the effect of family structure on the consumption quantity of aquatic products should be taken seriously, so that the aquatic products consumption of Chinese residents should be further promoted and also the aquatic products market can attain a development.展开更多

Torres, Macrozamia moorei F. Muell. ex C. Moore (Zamiaceae) were macerated and dissociated by Jeffrey's technique, rinsed with water, dehydrated and gold-plated for observation with scanning electron microscopes. The results showed that the pinna and rachis of the leaf tissues of the four cycad species possess many vessel elements and a few tracheid elements in the conducting tissue of the xylem. Annular, spiral, scalariform, pitted and reticulate vessels and some transitional types, including scalariform-pitted, scalariform-reticulate and reticulate-pitted vessels, were observed in the conducting tissues. The characteristics of the vessels of each species, and the evolutionary relation of four genera of cycads were analyzed. Compared with those of angiosperms, the structural characters of vessels of cycad are at the moderate level of evolution and more advanced than some primitive taxa of angiosperms and ferns. Vessels have been discovered in many genera of ferns, which are even more primitive than cycads. In many ferns, only vessel elements, but no tracheids are found in vascular tissue. In the present study, the authors discovered vessels in different genera of three families ofcycads which showed that the existence of vessels in primitive plant taxa is a widespread phenomenon. Vessel elements in vascular tissues of cycads have probably allowed cycads to adapt to various environmental stresses and enabled their persistence over their long evolutionary history. Cycads are the most primitive of the extant seed plants and the widespread existence of vessels in the group has broad implications for plant systematics, evolution and comparative morphology.展开更多

The results show that the migrants' domestic income has increased in the last 10 years, which originated from the tncreasing trend of active and extensive rural labor migration, while the resettlement has not influenced the domestic income significantly. The resettlement stimulates younger farmers to work.far away from home whose wages contribute nearly 80% of domestic income, The resettlement decreases their savings due to higher expenditure of daily life for those who work far away from home, and higher expenditure of food for those who stay at home, losing cultivated lands with irrigation system for vegetable. On the other hand. the increase of rural labor migration leads the migrants who stay at home to have access to more cultivated lands for rice and cotton, and the farmers also apply more fertilizer in the same cultivated land for more agriculture products. The resettlement makes most of migrants spend their savings on the improvement of their housing conditions due to not enough governmental financial support for new building. After the analysis, some factors that influence migrants' income and consumption are discussed. The paper may contritbute to the building of Poyang Lake Ecological Economic Zone.展开更多

According to the surveys, per capita net income level of the villages maintained consistent growth, as indicated by survey data on the years of 1930, 1936, 1957, 1986 and 1997, except for 1946 which saw decline, and enjoyed rapid growth particularly in the years of reform and opening-up after 1986. The changes reflect the national trendsustained decline of the proportion of net income from household operations versus eontinuous growth of the proportion wages income takes of the whole income.展开更多

Some of them are possibly starting to adopt modem corporate management practices to remain viable in a more competitive environment. However, changes in the business structure have not always been accompanied by changes in farm management practices. This study represents a theoretical and empirical investigation into farm modernization practices to provide perspective and recommendations to enhance farm business. Various aspects of farm modernization were considered, including temporal, economic and functional modernization. Critical elements of farm modernization were examined using a structural equation model of surveys, wherein questionnaires were delivered to 2,260 agricultural corporations across Japan in 2014 and 2016, generating 669 usable responses from rice farming corporations. Overall, these corporations demonstrated moderate degrees of modernization, indicating that they have not yet completely transitioned from conventional management styles to modem corporate management and that the farm-household complex system still exists for many of them. It was also found that farm modernization is significantly affected by both production and business management systems, although it was unclear whether a farmer's managerial capabilities were critical for farm modernization. The findings of this study indicate that current farming corporations may benefit from incorporating additional modernization practices. The analytical framework and results will help farmers to better understand their management practices and can be used to provide ideas for policy development to promote competitive farm businesses.展开更多

This paper casts light on the profound national income distribution and redistribution effects of changing ownership and economic reforms, as well as the microscopic household income distribution effects of changes in macroscopic distribution structure. Based on an analysis of changes in macroscopic distribution pattern, this paper explains the structural contradictions of national income distribution in China and their effects on China's economy, providing a theoretical analysis of income distribution for deepening supply-side structural reform.展开更多

文摘Rural poverty and poverty reduction are not only the focal issues that have attracted worldwide attention, but also the vital issues on people's livelihood that has attached great importance and aimed to be solved by the central and local governments of China. Based on the survey data of 354 farming households, this paper, taking the national poverty county of Lingao County, Hainan Province for an example, examined the characteristics of rural poverty of the county. Moreover, this paper established the spatial lag model(SLM) from five dimensions, namely, status of the household head, household structure, health status, income composition and traffic accessibility, to analyze the main influencing factors of rural poverty according to the values of Moran's I and the diagnosis of spatial dependence of the OLS model. It is found that the poor farming households gathered mainly in five towns in the north and southwest of the county, and the rural poverty have the characteristics of low educational level of the heads, more minor children, high population of farming peasants, high incidence of disease and low proportion of household wage-equivalent income. The results also showed that the variables such as the number of minor children, the number of migrant worker, the number of farming peasants and the proportion of wage-equivalent income have significant effectiveness on rural poverty, while the status of the household head, health status and traffic accessibility have little influence.

Overall, these corporations demonstrated moderate degrees of modernization, indicating that they have not yet completely transitioned from conventional management styles to modem corporate management and that the farm-household complex system still exists for many of them. It was also found that farm modernization is significantly affected by both production and business management systems, although it was unclear whether a farmer's managerial capabilities were critical for farm modernization. The findings of this study indicate that current farming corporations may benefit from incorporating additional modernization practices. The analytical framework and results will help farmers to better understand their management practices and can be used to provide ideas for policy development to promote competitive farm businesses.
