This essay explores the evolving international relationship of the two national park agencies that in 1968 began to offer joint training classes for protected-area managers from around the world. Within the British settler societies that dominated nineteenth century park-making, the United States’ National Park Service (NPS) and Canada’s National Parks Branch were the most closely linked and most frequently cooperative. Contrary to campfire myths and nationalist narratives, however, the relationship was not a one-way flow of information and motivation from the US to Canada. Indeed, the latter boasted a park bureaucracy before the NPS was established. The relationship of the two nations’ park leaders in the half century leading up to 1968 demonstrates the complexity of defining the influences on park management and its diffusion from one country to another.

The purpose of this paper is to provide an overview of the differences in the strength of social capital that is bonding and bridging two community groups, namely land-dwellers and Sama Bajo boat-dwellers in three islands in Wakatobi Marine National Park. This study used a post-positivistic research paradigm, and the primary data were collected by using a questionnaire to 240 respondents who represented the group of land-dwellers and Sama Bajo boat-dwellers on the islands of Wangi-wangi, Kaledupa, and Tomia. This research was also supported by qualitative data through in-depth interviews from several informants and desk studies. The results showed that bridging social capital relations tend to be weak in the two forms of interactions between the Sama Bajo and the land-dwellers on Wangi-wangi Island and Kaledupa Island, while bridging social capital tend to be secured in Tomia Island. We found that the social context through the historical links in the past and identity played a role in the relationship of bridging social capital and bonding social capital in the three communities as an analytical unit of this research.

The importance of lameness in dairy cattle in UK in terms of its economic consequences and welfare considerations is well documented (Russel and others, 1982). While such epidemiological work has identified factors of importance in the aetiology of the various conditions associated with lameness it has been less successful in apportioning their relative importance, particularly for those conditions affecting the hoof. A series of experiments has been conducted at the West of Scotland College over the period 1983 to 1989 mainly investigating the relationship of nutrition and lameness. In one of these Manson and Leaver (1988) found a significant difference in the prevalence of lameness between two groups of cattle fed complete diets containing either 16.1 or 19.8% crude protein. They also found a significant increase in mean locomotion score (LS) and commented that further studies were needed to understand the dietary processes by which the hoof of the cow was predisposed to such problems.The objective of this experiment was to investigate the influence of the type of protein source in the concentrate upon the locomotion of the cows, the incidence and prevalence of lameness and finally on hoof hardness, shape, growth and wear.

A review of cultivation changes in agricultural landscapes in the enclave village of Bromo TenggerSemeru National Park, Ngadas, Malang Regency Ngadas village is one example of an agricultural villagelocated in the mountains. Ngadas village is located in the enclave of Bromo Tengger Semeru National Park(TNBTS) in the Malang Regency, East Java. The dependence of the community on agricultural land makesNgadas have a strong agrarian image. Ngadas people do more activities in the fields than in the house. Asbasic landscape units in the form of mountains, they have a vulnerability if not used wisely. The problem ofvulnerability to erosion in the agricultural landscape, makes Ngadas Village interesting to study. Primarily,regarding the relationship of landscapes and land conservation efforts that must be made to a complexagricultural landscape. Therefore, there is a need for research that focuses on efforts to conserve land, especially in an agricultural landscape. Research is conducted through qualitative methods with spatial andqualitative descriptive comparative analysis. The results of the study show that changes in farming methodshave several disadvantages that can cause land degradation and reduced productivity in each period, includingthe shifting cultivation system to reduce nutrients, upper slopes planted with tubers and monoculture agriculture.Therefore, it is necessary to have the right recommendations, namely planting upper slopes with hard woodplants, planting with polyculture systems, and agroforestry systems applied on the upper slopes.

AbstractThe observation of the sky had an important rôle among the Maya, Aztecs and other prehispanic peoples of Mesoamerica. Their familiarity with the regularities of the apparent motion of the Sun, the Moon and bright planets is attested in a large amount of astronomical data contained in codices and monumental hieroglyphic inscriptions, as well as in their sophisticated calendrical system. On the other hand, the study of architectural alignments has disclosed that civic and ceremonial buildings were largely oriented on astronomical grounds, mostly to sunrises and sunsets on certain dates, allowing the use of observational calendars that facilitated a proper scheduling of agricultural and the associated ritual activities in the yearly cycle. Both accurate knowledge and other astronomically-derived concepts reveal that the significance attributed to certain celestial events by the ancient Mesoamericans can be explained in terms of the relationship of these phenomena with specific environmental and cultural facts, such as seasonal climatic changes and subsistence strategies. It was particularly due to its practical utility that astronomy, intertwined with religious ideas and practices, had such an important place in the worldview and, consequently, in the cosmologically substantiated political ideology of Mesoamerican societies

Taman Nasional Sebagau (TNS) or Sebangau National Park has been now striving to provide optimal benefits for the community surrounding its area through productive economic business development program, as it did in one buffer village, namely Sebangau Mulya. This program aims to improve community welfare, and as a form of community involvement in preserving the TNS area. However, the success of the program remains questionable. This study aims, first, to examine the development of productive economic business programs in Sebangau Mulya Village. Second, to analyze the effect of such program on the welfare of villagers. The research sample was 40 villagers who received direct assistance from the program. This figure account for 10% of the villagers. Descriptive analysis and multiple linear regression were used to study the relationship of 7 independent variables, namely facilitators (X1), institutions (X2), human resources capacity (X3), skills and knowledge of human resources (X4), type of productive economic assistance (X5), counseling and training (X6) and supervision (X7) with 1 dependent variable, i.e. community welfare. The results show that the program has been providing positive benefits, marked by the increase of cattle and goats number, compared to those provided by TNS management five years before. In addition, the program has been successfully tying villagers and TNS management in maintaining and managing the area according to the planned agenda. The factors that partially influence the beneficiaries welfare is skills and knowledge (X4), which is amounting to 26.80%. Since the community in carrying out productive economic businesses is in accordance with their skills and knowledge so that they are able to develop ideal businesses with the environmental conditions of Sebangau Mulya Village. Other six factors have no significant effect on villagers’ welfare.
