Sustainable indicator for feature attributes assessment of urban green space / Rabi'ah Ahmad and Abdul Nassir Matori

Urban green space features are natural or human-made facilities commonly found in community or recreational parks.Green features attributes such as size, design, usage, location and facilities are very influential in determining the satisfaction level of park users or visitors. There is a need to study the physical environment of green space that can be associated with the aspirations and demands of park users. For that reason, this research performed a study to design and develop a model for urban green space feature attributes. Two prominent recreational parks in Ipoh city have been chosen as a case study and the research investigates the influence of attributes features towards the needs of urban green space. The influence and effectiveness are measured using an integrated GIS mapping approach with qualitative assessments on satisfactory level of park visitors with the feature attributes available in both parks. A geo-referenced classified map of feature attributes of the recreational parks under study is initially prepared. Subsequentlyin the qualitative assessment, the variables measured on the physical and natural characters of the parks suggested that diversity of feature attributes for urban green space supports the social interaction for all age group. A sustainable indicator that defines the importance of urban green space feature components is proposed in defining the future Malaysian National Urbanisation Policy

Cloaking Neo-Imperialism in the Shadows of Human Rights and Liberal Peacebuilding

The concept of intervention to curtail humanitarian crisis in conflict zones has generated a great deal of polemics on the matters of state sovereignty, human rights, democracy and even the legitimacy of liberal peacebuilding. These discussions often include the justification or otherwise of both political and militarised interventions. While interventionism has become the most common approach by world powers, the concept of liberal peace building with its cloaked connotation of fostering and sustaining tranquillity and curtailing humanitarian crisis is seen by many as lacking in the not only the protection of people but also in ensuring sustainable peace. The view of some scholars is that, intervention in the name of humanitarianism raises so many questions as world powers continue resorting to militarised approaches that do not translate to the welfare of those they claim to protect. Instead, the outcome has been largely a convoluted and surging circle of crisis across many corners of the world.

Wound healing potential of aloe vera in climbing perch (Anabas testudineus).

Fresh gel portion of Aloe vera leaves was evaluated for the wound healing potential in climbing perch (Anabas testudineus). Fifteen adult climbing perch were divided into three groups. Group 1 received Aloe vera gel, group 2 received Betadine® antiseptic ointment (positive control) and group 3 received no treatment (negative control). Wound was created at the flank area using a punch biopsy (8 mm in diameter). One topical application was applied on the wound. Assessment of healing progress was carried out on day 10. Gross observation and histological studies were carried out. There was no significant difference in wound reduction among the groups. However, group 2 showed highest rate of healing followed by group 1 and group 3, and groups 1 and 3 had similar rate of healing. Histological examination on cellular activity of healing process showed increased thickness of epithelium layer, infiltration of inflammatory cells, presence of fibroblast cell and rearrangement of the cell

LINGKUNGAN VEGETASI DULU DAN KINI DI SITUS KOBATUWA II, NUSA TENGGARA TIMUR

Kobatuwa II site is located in the Soa Basin, at an altitude of 345 metres above sea level, surrounded by hills and volcanoes, i.e. to the North is Mount Weawavo, Mount Hill Rega, Nuke, and Mangu, South of there is the mountain Inerie and the mountain Logobada, on the West by Mount Meze (Wolo Meze), on the East by Mount Matataka, in the Southeast by Mount Abulobo astronomically, it lay in the 08 position 41 & 23.5 South latitude and longitude 121 05' & amp; 09,3 " East longitude. The purpose of this research is to know the state of vegetation environment that supports human life and the environment of prehistoric vegetation is now associated with the utilization of the natural resources that exist in the vicinity of the site. The method used is the method the vegetation survey and analysis of sediment pollen (Palinology). The survey results indicate that the site Kobatuwa II this included into the savanna vegetation blend, this is because the savanna in this region is dominated by an open forest canopies are composed by plants in the form of trees and shrubs and layers below it overgrown by a mixture of grasses and shrubs are tolerant of drought. The open Savanna Woodland pastures in this region is the dominant terrestrial type. Tree kesambi (Schleichera oleosa) which is one of the dominant species of tree savanna. From the results of the analysis of pollen while it can be noted that there has been a change in the vegetation which has been proven by the discovery of fossils of the Fagaceae only pollen found in wet forests. There has been also a changes in the vegetation of wet forest to savanna vegetation that is currently dominated by the expanse of grassland.Situs Kobatuwa II terletak di daerah cekungan Soa, pada ketinggian 345 meter dari permukaan laut yang dikelilingi oleh perbukitan dan gunung api, yaitu disebelah Utara Bukit Weawavo, Bukit Rega, Bukit Nuke, dan Bukit Mangu, di Selatan Gunung Inerie dan Gunung Logobada, di Barat Gunung Meze (Wolo Meze), di Timur Gunung Matataka, di sebelah tenggara Gunung Abulobo, secara astronomis terletak pada posisi 0841 23,5 LS dan 12105 09,3 BT. Tujuan penelitian ini untuk mengetahui keadaan lingkungan vegetasi yang mendukung kehidupan manusia prasejarah dan lingkungan vegetasi sekarang yang berkaitan dengan pemanfaatan sumberdaya alam di sekitar situs. Metode yang digunakan adalah metode survei dan analisa polen sedimen (Palinology). Hasil survei menunjukkan bahwa situs Kobatuwa II termasuk ke dalam vegetasi savana campuran, hal ini disebabkan karena savana di wilayah ini didominasi tajuk hutan terbuka yang disusun dari jenis tumbuhan berupa pohon maupun semak belukar dan lapisan bawahnya ditumbuhi campuran rumput dan perdu yang toleran terhadap kekeringan. Savana di daerah ini merupakan jenis terestrial yang dominan. Pohon Kesambi (Schleichera oleosa) merupakan salah satu jenis pohon yang dominan. Dari hasil analisis polen diketahui bahwa telah terjadi perubahan vegetasi sejak dulu, terbukti dengan ditemukannya fosil polen jenis Fagaceae yang hanya terdapat pada hutan-hutan basah. Telah terjadi pula perubahan vegetasi dari hutan basah ke vegetasi savana yang saat ini didominasi oleh hamparan padang rumput

Nationalism in Microstates : Realpolitik in the Two Samoas

The aim of this paper is to examine one of the divided nations, the Samoas in the Pacific. The Samoan Archipelago is divided into two microstates: Western Samoa, an independent country; and American Samoa, a US territory. Although they recognize themselves as a nation, they are not interested in unification at all. Although the separation has created differences in their modern administrative organizations, their educational systems, and their degrees of modernization, the main reason for their different attitudes toward unification lies in the realistpolitics (Realpolitik) of the microstates. In the case of the Samoas nationalism does not provide the power to recover the original united nation

Abiotic and biotic control of Argulus sp. among goldfish (Carassius auratus)

Argulus spp. are branchiuran crustaceans with a direct life cycle, therefore current aquaculture practice with a high density of potential hosts provides ideal conditions for effective transmission of this obligate ectoparasite. Chemicals are usually used to treat parasite infestation of fishes. However chemical treatments result in side-effects including environmental pollution, parasite resistance, alteration of zooplankton ecosystem, changes in certain hematological parameters and contamination of host organs. Thus there is a need for alternative measures to control parasitic diseases in the aquaculture industry. To date, there are no studies reported on biological control of fish lice, in particular the use of Thai silver barb (TSB) (Pontius gonionotus) to control Argulus population. In this study, the effectiveness of abiotic and biotic control methods for an ectoparasite infestation was examined. Therefore, an abiotic study was designed firstly to examine the effect of water current on parasite abundance and incidence of the fish lice, Argulus sp. among captive goldfish (Carassius auratus). Secondly, in a biotic study, the effectiveness of using TSB to reduce the parasite number was investigated and thirdly, to compare both the abiotic and biotic control methods in their effectiveness to reduce parasite number. The mean abundance and incidence of the ectoparasite, Argulus sp., on goldfish was measured. In the abiotic study goldfish infected with Argulus sp. was mixed with other susceptible goldfish hosts and kept in tanks with fast flowing or stagnant water. There was no difference in the parasite mean abundance and incidence between fast flowing and stagnant water. Thai Silver Barb which is a predator of the Argulus was introduced to the parasite infected goldfish for the biotic study. The mean parasite abundance was significantly lowered (P<0.05) after introducing the predator TSB into the tanks. Combination of both control methods did not further improve the effectiveness in reducing Argulus population. Hence this study showed that utilizing this method of biotic control among goldfish is definitely a future control solution. This study also showed that water current seemed to reduce Argulus transmission and population. The predator effect of TSB was lessened by the fast flowing current. The major finding in this study indicated that TSB was a very effective biological control where with only two TSBs, 96% of Argulus was removed in less than 24 hours. The number of TSB used in the biotic control did not affect the predator efficiency. It is suggested that the biological control tested in this study can be used to reduce Argulus population among goldfish in aquaculture settings
