Little Black Boxes: Legal Anthropology and the Politics of Autonomy in Tort Law

[Excerpt] Law’s interdisciplinary turn toward social sciences suggests a growing realization that jurists may not be independently equipped to explain the world in and upon which they act. But if law embraces empirical social science for its usable output, it struggles to make sense of the more interpretive disciplines such as anthropology. This has proven to be a major setback for both law and anthropology and confounds the historically productive rapport between the two fields stretching back more than a century. While it may be tempting to conclude that today’s legal academic misunderstands the interpretive turn in anthropology, that conclusion offers little to facilitate a rapport of the kind badly needed today

A Socio Religious Analysis of Suicides and its Impact on Economic Development

The aim of this paper is to gaining deeper insight into the reasons and consequences of condemned suicidal act from the socio-religious point of view and its impact on the economic development of a society. The condemned act of suicide and problems relating to it, keeping in view the available facts and figures is analysed in view of social and religious beliefs in the known religions of the world. Suicide is a serious public social problem. It is one of the important problems. Different reports on the causes and consequences of suicide have presented an extremely grim picture. It has threatened the life itself. The people resorted to suicides in huge numbers since last decade. Accordingly, the problem of suicide and other related matters may be viewed in terms of the role performance failure of the social & religious systems concerned and the social entities in their environment. Analogously, the problem may be interpreted in terms of the mal-functions of relationships based role on the reciprocity of expectations amongst the interacting social systems.Suicidal, Economics, Socio-religious, Beliefs, Rituals, problems, Reasons, Consequences, Role-Performance, Interaction.

Herschel PACS and SPIRE Observations of TWA brown dwarf discs

We present Herschel SPIRE observations for the TW Hydrae association (TWA) brown dwarf discs SSSPM J1102-3431 (SS1102) and 2MASSW J1207334-393254 (2M1207). Both discs are undetected in the SPIRE 200-500mu bands. We have also analyzed the archival PACS data and find no detection for either source in the 160mu band. Based on radiative transfer modeling, we estimate an upper limit to the disc mass for both sources of 0.1 M_Jup. The lack of detection in the SPIRE bands could be due to a paucity of millimeter sized dust grains in the 2M1207 and SS1102 discs. We also report a non-detection for the brown dwarf 2MASS J1139511-315921 (2M1139) in the PACS 70 and 160mu bands. We have argued for the presence of a warm debris disc around 2M1139, based on an excess emission observed at 24mu. The mid-infrared colors for 2M1139 are similar to the transition discs in the Taurus and Ophuichus regions. A comparison of the brown dwarf disc masses over a ~1-10 Myr age interval suggests a decline in the disc mass with the age of the system.Comment: Accepted in A&

Fatima Jinnah’s Concern for Women’s Technical Education

Madar-i-Millat Mohtarma Fatima Jinnah is known for her contribution to the uplift of various segments of Pakistani society which is indicated through her speeches, statements, messages and addresses at different functions and institutions, delivered on various occasions. Her special concern was that women of Pakistan which formed 50 percent of the population should be moulded to play their role on various aspects of human life. An important aspect to which she felt attached, was the promotion of technical education in the country. Along with men, she desired women of Pakistan should equally contribute to the industrial development of Pakistan. This could be done by spreading technical education amongst the girls of Pakistan. For this purpose she delivered a number of speeches, addressed various institutions and established various industrial homes.

Country Risk Ratings of Small Island Tourism Economies

Over the last twenty years, there has been a growing fascination within public and academic circles about the livelihood of islands with small populations and territory which are present in each of the world’s great oceans. The Small Island Tourism Economies analysed in this paper vary profoundly in their size, land area, and location. Moreover, they have depended heavily on financial aid from their former colonists for infrastructure development, which has declined dramatically since the collapse of Communism. These economies also differ in their narrow natural resource bases on land and in water, in their prospects for self reliance in economic development, and their overwhelming reliance on tourism as a source of exports. These economies are developing countries which need a consistent inflow of foreign direct investment to maintain economic growth. Such sovereign island economies differ in the extent to which they are home to a multitude of ethnic diversity, political systems, historical experience, economic and environmental vulnerability, ecological fragility, the types of risks facing private investors, and in the extent to which they are perceived as, or perceive themselves to be, insular and peripheral. In spite of the vast diversity as well as similarities, researchers are fascinated by the world of small island economies, and are intrigued by their unique features which cannot be addressed through a generalised set of rules. This paper analyses the geographical, historical, economic, tourism-oriented and institutional characteristics, as well as vulnerability to changes in the international economic, financial and political climates, of twenty Small Island Tourism Economies. The snapshot images provide a comparative assessment of the international country risk ratings, and highlight the importance of economic, financial and political risk ratings as components of a composite risk rating for Small Island Tourism Economies.Small size, Tourism, Volatility, Vulnerability, Country risk ratings, Economic risk, Financial risk, Political risk, Composite risk

Adapting ACME to the database caching environment : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Information Systems at Massey University

The field of database cache replacement has seen a great many replacement policies presented in the past few years. As the challenge to find the optimal replacement policy continues, new methods and techniques of determining cache victims have been proposed, with some methods having a greater effect on results than others. Adaptive algorithms attempt to adapt to changing patterns of data access by combining the benefits of other existing algorithms. Such adaptive algorithms have recently been proposed in the web-caching environment. However, there is a lack of such research in the area of database caching. This thesis investigates an attempt to adapt a recently proposed adaptive caching algorithm in the area of web-caching, known as Adaptive Caching with Multiple Experts (ACME), to the database environment. Recently proposed replacement policies are integrated into ACME'S existing policy pool, in an attempt to gauge its ability and robustness to readily incorporate new algorithms. The results suggest that ACME is indeed well-suited to the database environment, and performs as well as the best currently caching policy within its policy pool at any particular point in time in its request stream. Although execution time increases by integrating more policies into ACME, the overall time saved increases by avoiding disk reads due to higher hit rates and fewer misses on the cache

Models of Collapsing and Expanding Anisotropic Gravitating Source in f(R,T)f(R,T) Theory of Gravity

In this paper, we have formulated the exact solutions of the non-static anisotropic gravitating source in $f(R,T)$ gravity which may lead to expansion and collapse. By assuming the no thermal conduction in gravitating source, we have determine parametric solutions in $f(R,T)$ gravity with non-static spherical geometry filled with anisotropic fluid. We have examined the range of parameter for which expansion scalar become negative and positive leading to collapse and expansion, respectively. Further, using the definition of mass function the condition for the trapped surface have been explored and it has been investigated there exists a single horizon in this case. The impact of coupling parameter $\lambda$ has been discussed in detail in both cases. For the various values of coupling parameter $\lambda$, we have plotted energy density, anisotropic pressure and anisotropic parameter in case of collapse and expansion. The physical significance of the graphs has been explained in detail.Comment: 18 Pages, 8 Figures, Accepted for Publication in European Physical Journal
