. The objective was to study the habitat complexity of mite populations on Caryocar brasiliense trees under natural and cultivated field conditions. The study was performed in the municipality of Montes Claros, in the state of Minas Gerais, Brazil, over 3 years. Three types of areas were studied: 1) Cerrado, 2) pasture, and 3) a university Campus. Several chlorotic spots were detected on leaves with larger populations of Tetranychus sp. and Eutetranychus sp. (Tetranychidae). The greatest numbers of Agistemus sp. (Stigmaeidae) on leaves and Histiostoma sp. (Histiostomidae) and Proctolaelaps sp. (Ascidae) on fruits were observed in the pasture, and that of Histiostoma sp. on leaves in the pasture and on the university Campus. In general, the herbivorous mites (e.g., Tetranychus sp.) found on C. brasiliense plants were correlated with more clayey soils with a higher cationic exchange capacity; larger populations of mites (e.g., Agistemus sp. and Histiostoma sp.) were found on the C. brasiliense trees with the largest crown sizes; and associations between predator mites (e.g., Agistemus sp.) and phytophagous mites (e.g., Tetranychus sp.1) were observed. Greater habitat diversity and more complex plant architectures favored the mite populations. The positive effect of loamier soil on herbivorous mites indicates that these species are adapted to Cerrado conditions. Some recorded species of herbivorous mites can be pests in commercial plantations of C. brasiliense.

A demonstration vegetable garden was constructed for students in elementary, middle and high schools to expose them to agricultural science. On Charter Day, a University-wide celebration, students were invited to the garden on the University campus. The purpose of this project was twofold: (1) for participants to learn how to make a garden and (2) for visitors to see a variety of available crops and cultural techniques. Approximately 30 vegetable crops were grown. The garden also presented some cultural practices to improve plant development, which included weed control by solarization, mulching, a drip irrigation system, staking, shading and crop cover. Different types of compost bins were shown and various nitrogen-fixing legumes were displayed as useful hedge plants for the garden.

Abstract Background A healthy youth is considered the major human resource for any country development. They are suffering from unmet health needs. Considering these needs and their attitude towards the use of youth health center (YHC) services would help to improve both the quality and quantity of these services. Objectives To identify the students’ perceived health needs and their attitude towards use of the YHCs in Assiut University campus, Upper Egypt a cross-sectional study was conducted among 305 randomly selected university students. Data were collected using an interviewer-administered questionnaire. Results The majority of the students (80%) said that youth have special health needs. The most reported needs were psychological support, health education on different topics including reproductive health and sexually transmitted diseases, and nutritional services respectively. There was a high perception among surveyed students (71.5%) that the existing health services are inadequate for meeting their needs. Counseling, laboratory services, and premarital examination were the most frequently reported services mentioned by youth to be offered in YHCs. The majority (78.1%) preferred the health provider to be of the same sex. Despite the prevailing conservative culture in Upper Egypt, the students had positive attitude towards availability of sexual and reproductive information and establishment of a YHC in the university campus. A low awareness rate (15.1%) about the already existing YHC in university campus was revealed. Conclusion University students perceived that there are unmet needs for youth-specialized services, mainly for providing sexual and reproductive information, and establishment of an on-campus YHC. The study provides important information for policymakers about the perspectives of youth which should be taken into consideration when new YHC are planned and implemented.

As colleges and universities to improve the overall level of the building, a good campus landscape is an important part of campus construction. In this paper, the new campus of the University of Linyi landscape ideas, landscape planning and design in general, the central area of landscape design and water system planning in four areas, described the landscape in Linyi University campus to block a corridor decorated with a matrix structure for the model of the landscape, ecological as a precondition to build growth and open campus planning and design ideas. To the construction of a modern university campus landscape play a role in learning.

Abstract This paper presents findings from a qualitative study that investigated seven female Saudi Arabian students of the University of Liverpool’s online Masters programmes. Qualitative, first-person research methods and hermeneutic phenomenology were chosen for the analysis and interpretation of transcripts (Langeveld, 1983; van Manen, 1997; Creswell, 2007, Roth, 2012). The principles of cultural anthropology (Hall & du Gay, 1996; Hannerz, 1992; Lull, 2001; Coleman, 2010) were used to take a snapshot of the interviewees’ particular world to provide an overview of the Saudi Arabian culture where the role of women is at the centre of academic, political, religious and social debate These findings reflect the participants’ everyday lives, identities, values and beliefs, presented in a self-reflective, personal ‘life-world’ story of one single Saudi Arabian woman. The findings demonstrate that the primary motivators in choosing online international education to further study are existing limitations of travelling to a university campus and customary gender-segregated education in Saudi Arabia. As a contrast, international online education offers the opportunity to gain up-to-date research-based knowledge in their chosen profession, learn critical thinking and problem solving skills and communicate with male and female students from different cultures.

At the beginning of XX Century there was a great advance in Spanish science and culture, but not in universities. The Second Republic launched a great university reform inspired by other European and American universities. The introduction of research, new studies plans, and the proliferation of university colleges, were some of the keys to the new Spanish university model. The project of the university reform of the Second Republic was actively developed until the summer of 1936, when many faculties, engineering schools, research laboratories, residences and other institutions of the Madrid Campus were already opened. The experience of Madrid was adopted by other Spanish uni-versities. In some cases, pedagogical and research methodologies have been at the forefront internationally. Access to university education and research for women has become ubiquitous. Among the university teachers were leading representatives of the Silver Age of Spanish sci-ence and culture. However, this project of reforming Spanish universi-ties was thwarted by the mutiny of July 18, 1936, one of the goals of which was to stop the modernization process launched by the Second Republic. The mutiny led to a bloody civil war, during which the new-ly opened faculties of the university campus became a zone of fierce fighting, buildings were destroyed, as was the entire university reform project.
