The majority of these changes have affected the growth traits of fish life history, which include a smaller size-at-age, an earlier age-at-maturation and among others. Currently, the causes of these life history traits changes still require systematic analyses and empirical studies. The explanations that have been cited are merely expressed in terms of fish phenotypic adaptation. It has been claimed that the original traits of fish can be recovered once the intensity of exploitation of the fish is controlled. Sustained environmental and fishing pressure will change the life history traits of most fish species, so the fish individual's traits are still in small size-at-age and at earlier age-at-maturation in exploited fish populations. In this paper, we expressed our view of points that fishing gear has imposed selectivity on fish populations and individuals as various other environmental factors have done and such changes are unrecoverable. According to the existing tend of exploited fish individual's life history traits, we suggested further researches in this field and provided better methods of fishery management and thereby fishery resources protection than those available early.展开更多

In the years immediately following these key events, protected area acts and regulations were strictly applied and the role of local people in managing natural resources was neglected. However with the passage of time, and with changes in the socio-political and economic characteristics of Nepal, management regimes have shifted towards a more liberal model which recognizes more clearly the contributions of people living and working within protected areas. Recently, landscape level conservation models including the designation of multiple use areas have been utilized in the development of management plans for protected areas in Nepal. Conservation agencies have attempted to tackle challenges such as land use conflict, poaching and smuggling of wildlife parts and illegal harvesting of highly valued medicinal herbs through regulation, but these efforts are not always successful. We recommend a holistic conflict resolution approach which recognizes and resolves the different needs of all stakeholders.展开更多

Although humans have been interested in quicksand over the years (particularly through film), there remains a void of research into the meaning and value in the lives of those who engage in a recreational pursuit of quicksand, most notably the community of individuals who self-describe as sinkers. The purpose of this exploratory study was to examine if sinking can contribute to a participant’s understanding of history and natural resources at state parks. In order to obtain a better understanding of the effects, a qualitative study was conducted in the summer of 2016 at Stephen C. Foster State Park, a state park adjacent to Okefenokee Swamp. The researchers exercised grounded theory techniques and inductive content analysis to analyze interview data and compile coded text into four main categories: learning, enjoyment, traveling, and economic impact. Findings suggest that participants believed their knowledge of park history and natural resources increased through a recreational pursuit of quicksand.展开更多

This is one of the most effective ways to exploit limited oil reserves more economically and efficiently. There are two steps in closed-loop reservoir management: automatic history matching and reservoir production opti- mization. Both of the steps are large-scale complicated optimization problems. This paper gives a general review of the two basic techniques in closed-loop reservoir man- agement; summarizes the applications of gradient-based algorithms, gradient-free algorithms, and artificial intelligence algorithms; analyzes the characteristics and application conditions of these optimization methods; and finally discusses the emphases and directions of future research on both automatic history matching and reservoir production optimization.展开更多

Management accounting has long lived in the shadow of financial accounting, and has been often accused of fostering productivity rather than creativity. The revolution involving the business environment in the last decades has much improved the role of creativity and innovation and the adaptability of the fn-m to the context often was a key to success. This article supports the innovative role of management accounting in the post-modem era, aimed at reducing the strategic dominance of the increasing uncertainty.展开更多

This square was realized in 1935 by the architect Salvatore Caronia Roberti and is representative of the 1930s' fascist regime. The aim of this research is the knowledge of this urban space: the historical references, the compositive choices, the planimetric layout and its geometric rigor, and the monumentality and representativeness of the buildings overlooking the square. The research used the tools of Survey and Representation to better understand the dimensional ratios both at the urban and architectural scale. We have carried out an integrated survey (direct, photogrammetric, 3D laser scanning) in order to acquire a whole set of information essential to describe, document, and appreciate all the features of this urban space. Our investigation started by analyzing the historical documents preserved at the Historic Archive of the city of Enna (project drawings, letters, and historical images) to better understand why some decisions have been taken. The final result represents the historical memory up-to-date of the whole urban space, and it allows any academics to investigate more about the project: the initial decisions, the conservation state, and the possible and more coherent interventions of maintenance and preservation.展开更多

The first issue is when management accounting system was formed; the second is how to evaluate its development in subsequent decades; the third is how to evaluate the development of practice and research of management accounting in almost twenty years after Relevance Lost was published. The role of Relevance Lost in practice and theoretical research of management accounting is widely recognized, and the disagreement with it in this paper is in the specific area of the development history of management accounting. The authors of this paper believe that the development, through having its ups and downs over time, is generally speaking a continuous process, not separated by disconnected phases, leaping from one to another. Along with the progress in practice and research, researchers and practitioners are deepening their understanding about the theoretical foundation and practical development of management accounting. The history of development of management accounting is consistent with the process people gradually understand it.展开更多

This was accomplished by analyzing surviving historical documents, including budgetary notes and a diary. The Kabu-ido system was a customary institution for groundwater management in a ring levee area of the Noubi Plain in Japan that consisted of three programs: restriction of groundwater pumping through a permit system, groundwater pricing and economic compensation. The system was created in the 1810s and survived for 100 years. This paper covers the Kabu-ido system from the 1810s to the 1860s, the first half of the 100-year history. Excessive groundwater pumping is not a new environmental problem. Although many case studies have investigated remedial actions, few have investigated how local residents addressed the problem before the 20th century because of a lack of documents. The Kabu-ido system is an exception in which of the procedure was documented in writing. The historical data indicate that it was a pioneering institution for groundwater management.展开更多
