Payments for Environmental Services (PES) have been widely adopted worldwide as a new market-based initiative for conservation and environmental management. In Indonesia several PES initiatives exist ranging from watershed and terrestrial to marine ecosystem. Nevertheless, developing and managing PES programs in Indonesia are exacerbated by the complexity of institutional arrangements. Fiscal constraints are still the main obstacle of sustainable financing of PES mechanism. Rules and regulations with regard to PES fiscal mechanism are rather lacking, making it difficult for effective management of PES programs. As a consequence, efficient mechanism between users (firms) and environmental services is rather weak. This paper explores such a problem based on case studies of two existing PES programs in Indonesia. The paper analyzes the complexity of fiscal mechanism as a derivative of regulations and discusses challenges to overcome the constraints. © 2013 The Authors. Source

The Bergman's minimal model of glucose and insulin plasma levels is commonly used to analyse the results of glucose tolerance tests in humans. In this paper, we present the modified minimal model with plasma insulin compartment under the assumption that if the plasma glucose compartment drops below the basal glucose levels, the rate of insulin entering the plasma glucose compartment is zero. Insulin is cleared from the plasma insulin compartment at a rate proportional to the amount of insulin in the plasma insulin compartment. The modified minimal model was used to study the effect of physical exercise via parameters of a mathematical model to qualitative the magnitude of changes in insulin sensitivity (S I) and glucose effectiveness (S G) in response to exercise in type 2 diabetes and healthy human. The short-term effects of physical exercise in type 2 diabetes did not improve S G, but markedly improved the low S I values found in type 2 diabetes, indicating that the effects of exercise on S I are quantitatively important in the interpretation of training-related S I changes and may even be therapeutically useful in type 2 diabetes patients. Physical exercise is indicated either to prevent or delay the onset of type 2 diabetes or to assure a good control of type 2 diabetes by increasing insulin sensitivity. © 2013 Springer-Verlag Berlin Heidelberg.

We report a comprehensive study of the fourth rank tensor describing third harmonic generation (THG) and electric field induced second harmonic (EFISH) in centrosymmetric material from two different viewpoints: group theory and the simplified bond hyperpolarizability model (SBHM). We show that the fourth rank tensor related to THG and direct current EFISH can be reduced to two independent elements, whereas SBHM always gives only one, reproducing perfectly well EFISH experimental results in a metal oxide semiconductor. We argue that it is possible to reduce the fourth rank tensor describing EFISH to a third rank tensor and further deliver a classical explanation of EFISH regarding symmetry breaking, where the term containing r3 in the potential immediately leads to second harmonic generation. © 2015 Optical Society of America.

Polymorphic microsatellite DNA parentage analysis was used to investigate the spatio-temporal variability of selfrecruitment in populations of two anemonefishes: Amphiprion ocellaris and A. perideraion. Tissue samples of A. ocellaris (n = 364) and A. perideraion (n = 105) were collected from fringing reefs around two small islands (Barrang Lompo and Samalona) in Spermonde Archipelago, Indonesia. Specimens were genotyped based on seven microsatellite loci for A. ocellaris and five microsatellite loci for A. perideraion, and parentage assignment as well as site fidelity were calculated. Both species showed high levels of self-recruitment: 65.2% of juvenile A. ocellaris in Samalona were the progeny of parents from the same island, while on Barrang Lompo 47.4% of A. ocellaris and 46.9% of A. perideraion juveniles had parents from that island. Self-recruitment of A. ocellaris in Barrang Lompo varied from 44% to 52% between the two sampling periods. The site fidelity of A. ocellaris juveniles that returned to their reef site in Barang Lompo was up to 44%, while for A. perideraion up to 19%. In Samalona, the percentage of juveniles that returned to their natal reef site ranged from 8% to 11%. Exchange of progeny between the two study islands, located 7.5 km apart, was also detected via parentage assignments. The larger Samalona adult population of A. ocellaris was identified as the parents of 21% of Barrang Lompo juveniles, while the smaller adult population on Barrang Lompo were the parents of only 4% of Samalona juveniles. High self-recruitment and recruitment to nearby island reefs have important implications for management and conservation of anemonefishes. Small MPAs, preferably on every island/reef, should ensure that a part of the population is protected to enable replenishment by the highly localised recruitment behaviour observed in these species. © 2014 Madduppa et al.

Anthropometric data are a prerequisite for designing agricultural tools and equipment that enable workers to achieve better performance and productivity while providing better safety and comfort. A set of thirty anthropometric dimensions was collected from a total sample of 371 male and female farm-workers from three different regions (west, central and east) of Java Island, Indonesia. The mean stature is 162.0cm and 152.5cm, the sitting height is 82.9cm and 77.4cm, and the body weight is 57.1kg and 52.3kg for male and female subjects, respectively. The index of relative sitting height (RSH) was 0.51 on average for both male and female subjects. Significant differences are found in most of the anthropometric dimensions between gender and regional data groups as well. Compared with groups of people from several other countries, the anthropometric dimensions of Indonesian people are quite similar to Indian people, but are relatively smaller than Filipino, Chinese, Japanese, British, and American people. An attempt was conducted to illustrate the use of this anthropometric database and ergonomic considerations in refining the design of traditional tools and equipment commonly in use for rice farming operations. © 2015 Elsevier Ltd and The Ergonomics Society.
