A comparison of the Bering Sea, Gulf of Alaska, and Aleutian Islands large marine ecosystems through food web modeling / by K. Aydin ... [et al.]

Detailed mass balance food web models were constructed to compare ecosystem characteristics for three Alaska regions: the eastern Bering Sea (EBS), the Gulf of Alaska (GOA), and the Aleutian Islands (AI). This paper documents the methods and data used to construct the models and compares ecosystem structure and indicators across models. The common modeling framework, including biomass pool and fishery definitions, resulted in comparable food webs for the three ecosystems which showed that they all have the same apex predator—the Pacific halibut longline fishery. However, despite the similar methods used to construct the models, the data from each system included in the analysis clearly define differences in food web structure which may be important considerations for fishery management in Alaska ecosystems. The results showed that the EBS ecosystem has a much larger benthic influence in its food web than either the GOA or the AI. Conversely, the AI ecosystem has the strongest pelagic influence in its food web relative to the other two systems. The GOA ecosystem appears balanced between benthic and pelagic pathways, but is notable in having a smaller fisheries catch relative to the other two systems, and a high biomass of fish predators above trophic level (TL) 4, arrowtooth flounder and halibut. The patterns visible in aggregated food webs were confirmed in additional more detailed analyses of biomass and consumption in each ecosystem, using both the single species and whole ecosystem indicators developed here

Analisis Simulasi Penerapan Akuntansi Sumber Daya Manusia Terhadap Perbandingan Kinerja Keuangan (Studi Kasus Pada PT Bank Pembangunan Daerah Lampung Tahun 2012-2014)

Accounting provides financial information which is used by manager to make decisions. Conventional accounting (accounting which accepted generally) treats human resources costs improperly which resulted in irrelevant financial information. Human resources accounting is the answer of problems faced by manager to make decision. PT Bank Pembangunan Daerah Lampung is a company which operational activities engaged in services, which is fully aware that human resources\u27 dominant role as one of the main factors to support the success of the company. It\u27s shown from its attempt done in recruitment, selection, development, and training of the employees to support its employment candidates, yet PT Bank Pembangunan Daerah Lampung haven\u27t applied human resources accounting. This study purposed to analyze the financial performance with profitability ratio analysis and compare the before and after the appliance of human resources accounting simulation by experimental descriptive research method. The types of data used is secondary data from human resource costs sourced by financial statements PT Bank Pembangunan Daerah Lampung obtainable website. The result shows the financial performance of PT Bank Pembangunan Daerah Lampung gets better after human resources accounting is applied, as shows in the human resources accounting simulation. It caused cost of human resouce (acquisitions and development) into an investment not as expense

INVESTIGATING THE CORRELATION BETWEEN STUDENTS’ GRAMMAR MASTERY AND READING COMPREHENSION ACHIEVEMENT

Abstract: The objectives of the study were to find out whether or not there were a significant correlation between students’ grammar mastery and reading comprehension achievement and a significant contribution of the students’ grammar mastery to their reading comprehension achievement. There were 120 eighth graders of one junior high school got involved as participants of this study. The data were collected by using grammar and reading comprehension tests and analyzed statistically by applying Pearson product moment correlation analysis and linear regression. The findings showed that there was a strong positive correlation between the students’ grammar mastery and their reading comprehension in which r-obtained (0.739) was higher than r-table (0.1793). The regression analysis also showed that there was significant contribution of the students’ grammar mastery (54.7%) to their reading comprehension achievement.Keywords: grammar mastery, reading comprehension, eighth grader

The Behavior of Fishpond Farmers with Silvofishery Insight and its Effects on Biodiversity of Macrozoobenthos in Mangrove Ecosystem of Coastal Area

Mangrove ecosystem is an open ecosystem of various orientation of human interests in coastal areas, so that its position as common property makes these ecosystems are vulnerable to all forms of exploitation and environment manipulation that occur in it. Some areas in South Sulawesi Province has experienced such things, one of which is Sinjai district which has an area bordering dominated coastal mangrove vegetation has been experiencing a crisis of environmental degradation, at least negative impact has been felt since 10 years ago. The reason for the coastal area is converted to farms and settlements area. In optimizing the role of fish farmers against Silvofishery program which has been running since 10 years ago, and to avoid the negative impact of prolonged crises of environmental degradation, the need to study the problem formulation through research questions, as follows: (1) Whether the insight of environment knowledge, ecosystems, conservation, attitude and motivation affect the behavior of fish farmers with Silvofishery insight? (2) Whether the behavior of Silvofishery concept can maintain biodiversity that meet the natural standards as ecosystem feasibility? Based on the problem formulation, the objectives of this study was; (1) to analyze the effect of knowledge, attitude and motivation of fish farmers against Silvofishery insightful behavior, (2) to analyze the effect of behavioral patterns of fish farmers with Silvofishery insight that can maintain the natural biodiversity as ecosystem feasibility standard. With a package of biodiversity analysis and quantitative approaches through Structural Equation Model analysis of case-study research data obtained through questionnaires distribution, so that obtained the results below. The results of study showed that: (1) the knowledge insight does not affect the behavior of fish farmers with Silvofishery insight; (2) there is a positive contribution to the fish farmers attitude with Silvofishery insight; (3) there is a positive contribution of motivation to the behavior of fish farmers with Silvofishery insight; (4) patterns of Silvofishery insightful behavior of fish farmers showed biodiversity that meet natural standard of ecosystem feasibility. Thus, the exogenous variables of study ie research knowledge, attitudes and motivation, directly has a major role in influencing the behavior of endogenous variables of Silvofishery insight as a concept of integrated ecosystem management that are environmentally friendly and can maintain the natural biodiversity as a guidance of viable environment quality in a sustainable manner
