Web content analysis of agricultural cooperatives located in Turkey

After the appearance of the globalization process post of 1980＇s, world has becaming a big village, that had been brought many important outcomes related with cooperatives which are aimed to emit the capital to the base. These conditions have been forced the movement to adopt themselves to this process vitally. As of year 2007, there are 26 several types of cooperatives with 90.086 unit cooperatives which have total number of 8,561.618 partners that are all dependent to Turkish cooperative association as well as Ministry of Industry and Commerce. In this study, the web sites of Turkish agricultural cooperatives were examined in terms of their contents. Also, it is tried to find out the sufficiency level of their electronic marketing activities. Within the context of this study, web sites of 5 agricultural cooperatives are examined in terms of their design.

Communication for Social Mobilization： An Evaluative Study of the National Immunization Campaign in Nigeria

This study critically evaluates the communication strategies used in the campaign for social mobilization for the National Programme on Immunization in Nigeria. Its objective is to determine the communication factors that contributed to the participation of individuals and groups in the programme at the federal, state, and local government levels. Fifty four subjects, consisting of five policy and decision makers in health, information, and education sectors, five community leaders, 15 media personnel, 15 state health officials, 20 LGA officials, 12 representatives of non-governmental organizations, five opinion leaders, seven clinic staff, six state health officials, and eight mothers were purposively selected from the federal level and two states; Imo and Kano states of Nigeria. Methodology used for data collection includes individual and group interviews and critical evaluation instruments. Findings show that the mass campaign strategy proved to be the most effective strategy for reaching both rural and urban dwellers and specific groups with immunization messages. The alliance between the health workers and community leaders, social groups, NGOs and the information education sectors, had a multiplier effect on the campaign and helped to create feelings of solidarity. The ubiquitous channels of traditional and religious leaders and youth groups helped to spread immunization messages and gain support for the programme. Women and women groups were adequately involved at the federal level and in Imo State, a Christian state in the South-East. This was not the case in Kano State, a Muslim state in the north due to sociocuitural factors. The sustainability of the programme lies in more integration, more intersectoral collaboration, more institutionalization, more quality verification, more decentralization, greater local political commitment, and a multistrategic approach to campaign planning and implementation.

Influence of rolling ways on microstructure and anisotropy of AZ31 alloy sheet

Two rolling ways,unidirectional rolling and cross rolling,were carried out on twin roll cast AZ31 alloy sheet to study the influence of strain path change on the evolution of the rolling microstructure and texture as well as the anisotropic properties of AZ31 alloy sheet with microscopy,X-ray diffraction technique and tensile tests.It is found that cross rolling gives rise to more uniform microstructure and stronger texture intensities compared with unidirectional rolling.The differences in the microstructure and texture intensities are reflected in the anisotropy characterized by the difference in the yield stress and the fracture elongation that were measured along directions in the rolling plane at angles of 0■,45■and 90■from the rolling direction.

Market Transition, Labor Market Segmentation and Organizational Mobility

On the basis of data from the 2008 Chinese General Social Survey, this paper analyzes the changing organizational job mobility patterns of members of society in a segmented labor market. The structure of labor market segmentation is based on differences in the power of different labor sectors to distribute social resources, leading to further differences in their power of ＂attraction＂ or ＂repulsion＂ that influence people＇s organizational mobility. These forces are strongest in the primary labor market, lessening the possibility that workers will leave their jobs and raising the possibility of cross-sector mobility. In the course of China＇s market transition, changes in the power to allocate social resources have entailed changes in the structure of labor market segmentation, changes that have been reflected in organizational mobility. Our examination of changing modes of organizational mobility reveals that the structure of urban labor market segmentation has changed from being mainly systemic at the outset of reform and opening up to the current coexistence of systemic segmentation and market segmentation.

Effect of puerarin on neural function and histopathological damages after transient spinal cord ischemia in rabbits

Objective: To investigate the effect of puerarin on the neural function and the histopathological changes after ischemic spinal cord injury in rabbits. Methods: Thirty male New Zealand white rabbits were randomly divided into three groups as follows: puerarin group (n=10) receiving intravenous infusion of 30 mg/kg puerarin for 10 minutes, control group (n=10) receiving intravenous infusion of the same volume of normal saline as puerarin for 10 minutes, and sham operation group (n=10) undergoing only the surgical exposure of the abdominal aorta. Temporary spinal cord ischemia was induced by infrarenal aortic occlusion for 20 minutes and followed by reperfusion. The neural status was scored with the Tarlov criteria at 8, 12, 24 and 48 hours after reperfusion. All the animals were killed at 48 hours after reperfusion and the spinal cords (L 5) were removed immediately for histopathological study. Results: The neural function scores at 8, 12, 24 and 48 hours after reperfusion were higher in the puerarin group and sham operation group than those in the control group (P< 0.05). More normal motor neurons in the anterior horn of spinal cord were present in the puerarin group and sham operation group than those in the control group (P< 0.01). There was a strong correlation between the final neural function scores and the number of normal motor neurons in the anterior horn of spinal cord (r= 0.839, P< 0.01). Conclusions: Puerarin can significantly ameliorate the neural function and the histopathological damages after transient spinal cord ischemia in rabbits.
