Contamination of the coastal waters of Bermuda by organotins and the triazine herbicide Irgarol 1051
No full textA study of the distribution of the 'booster' biocide 2-methylthio-4-tert-butylamino-6-cyclopropyl amino-s-triazine (Irgarol 1051) was carried out in the coastal waters of Bermuda. Irgarol 1051 concentrations (as determined by GC/MS) up to 590 ngl-1 have been measured within Hamilton Harbour. The data presented herein unequivocally demonstrate contamination of the coastal system of Bermuda by Irgarol 1051. Concurrently, TBT concentrations were measured and results indicate that levels are falling through legislated changes in antifouling treatments, from 220 ngl-1 in 1990 to <20 ngl-1 (as Sn) by 1995, in the open water area of Hamilton Harbour. Concentrations of TBT immediately offshore from a boatyard were found to be >600 ngl-1 (Sn), indicating continuing release due to painting operations and sediments in the area

The effects of domestic violence on behavior problems of preschool children
No full textUsing four waves across 5 years of a recent longitudinal dataset, this study examined whether domestic violence toward mothers by a child’s father at Year 1 had long-term effects on preschool children’s externalizing and internalizing behavioral outcomes at Year 5 directly or indirectly through maternal mental health and parenting at Year 3. The study also analyzed whether the effects differed depending on poverty and marital status. Findings from structural equation modeling conducted in AMOS showed that domestic violence toward mother by a child’s father at Year 1 was associated with poor maternal mental health and greater use of spanking at Year 3, which in turn were related to greater children’s externalizing and internalizing behavior problems at Year 5. These associations among latent variables in the models still remained significant even when control variables were included in the analyses; only the path between maternal mental health at Year 3 and children’s internalizing behavior problems at Year 5 was no longer significant. Notably, the direct effect of domestic violence on children’s behavior problems was still significant even after including mediators and control variables in the analyses. Findings from the multiple-group analyses for fully-controlled models revealed that the effects of domestic violence at Year 1 on children’s behavioral outcomes at Year 5 varied by poverty and marital status. Regarding the moderating role of poverty status, contrary to the hypotheses, the overall impacts of domestic violence at Year 1 on both types of behavioral outcomes of children at Year 5 were bigger for nonpoor than for poor families. With respect to the moderating role of marital status, the impacts of domestic violence at Year 1 on children’s externalizing behavior problems at Year 5 were bigger for unmarried-mother than for married-mother families. In contrast, the impacts of domestic violence at Year 1 on children’s internalizing behavior problems at Year 5 were bigger for married-mother than for unmarried-mother families. Findings from this study highlight that the effects of domestic violence on the behavior problems of preschool children are long-term, that those effects vary by socioeconomic categories, such as poverty and marital status, and, therefore, that children’s and their mothers’ needs in violent families vary widely as well. Policy, practice, and research implications are discussed.Ph. D.Includes bibliographical referencesby Jeong Ah Yo
Investigation on cycling and calendar aging processes of 3.4 ah lithium-sulfur pouch cells
No full textMuch attention has been paid to rechargeable lithium-sulfur batteries (Li–SBs) due to their high theoretical specific capacity, high theoretical energy density, and affordable cost. However, their rapid c fading capacity has been one of the key defects in their commercialization. It is believed that sulfuric cathode degradation is driven mainly by passivation of the cathode surface by Li2S at discharge, polysulfide shuttle (reducing the amount of active sulfur at the cathode, passivation of anode surface), and volume changes in the sulfuric cathode. These degradation mechanisms are significant during cycling, and the polysulfide shuttle is strongly present during storage at a high state-of-charge (SOC). Thus, storage at 50% SOC is used to evaluate the effect of the remaining degradation processes on the cell’s performance. In this work, unlike most of the other previous observations that were performed at small-scale cells (coin cells), 3.4 Ah pouch Li–SBs were tested using cycling and calendar aging protocols, and their performance indicators were analyzed. As expected, the fade capacity of the cycling aging cells was greater than that of the calendar aging cells. Additionally, the measurements for the calendar aging cells indicate that, contrary to the expectation of stopping the solubility of long-chain polysulfides and not attending the shuttle effect, these phenomena occur continuously under open-circuit conditions.</p
Ah ku and karayuki-san : prostitution in Singapore, 1870-1940 /
No full text"This history describes and analyses brothel prostitution in Singapore between 1870 and 1940. The vital role of Chinese and Japanese prostitutes in sustaining Singapore's pre-war economy and society has not been fully recognized. Starting with village backgrounds in rural China and Japan, and the hazards of the trade in women and children, the author follows the prostitutes through their encounters with brothel life in general, and in particular explores their routines and crises of earning, spending, social relations, leisure, mobility, disease, and death. A rare portrait of the daily lives of the ah ku and karayuki-san emerges. It is also a historical account of human nature, of human relationships compelled by the pride and prejudice of the human spirit. The author has used Coroners Inquests and Inquiries, statistical and other records, as well as photographs and oral reminiscences to resurrect the lives of the ah ku and karayuki-san.""By organizing the case material around themes relating to the workplace and working conditions, the author has converted a mass of depositions into an 'inner history', evoking a milieu and sentiment whose details were often clouded by an atmosphere of unease, irony, and danger: of Loh Sai Soh's fatal objection to Lam Loh Suh leaving the brothel: of Otoyo and her penalized client of two years, Lance-Corporal Albert Chacksfield; of the beautiful Duya Hadachi, her experiences of a relationship strained beyond endurance, and the deadly struggle between her paramours; and many, many others. Such ordinary people tumble from the pages of the records: they talk about choice of partners, love and betrayal, desperation and alienation, drawing us into their lives. These short vignettes turn out to have remarkable implications for the pace and texture of Ah Ku and Karayuki-san, and for stitching together a tapestry of poverty, sexual antagonisms, subordination, and conflict in the social history of prostitutes' and coolies' experiences. Combining a life-span approach with collective biography, the author has created a personal history of the ah ku and karayuki-san's times closely based on intimate experience, while still paying careful attention to the larger historical influences - the institutions, processes, and interactions - which determined their fates in Singapore. This social history is the companion volume to Rickshaw Coolie: A People's History of Singapore (1880-1940)."--Jacket.Maps on lining papers.Includes bibliographical references (pages 414-428) and index.Pt.

Maqasid al-Syari’ah dalam Penegakkan Hukum Lalu Lintas di Indonesia
No full textThe high number of traffic accidents in Indonesia occurred because the traffic law enforcement does not run optimally. This paper tried to explore the rules regarding the traffic that have been contained in the form of Law no. 22 of 2009 concerning Road Traffic and Transportation and other regulations from an Islamic legal point of view, especially through the study of maqashid al-shari’ah. The maqashid al-shari’ah approach is used as an approach because maqashid explains the wisdom behind the rules of Islamic shari’ah. The maqashid approach used by the author in this paper is the maqashid classification used by Jamaluddin al-Athiya which divided maqashid into four domains, they are maqashid al-shari’ah in the individual realm, maqashid al-shari’ah in the family realm, maqashid al-shari’ah in the realm of the ummah and maqashid al-shari’ah in the realm of humanity. It can be concluded that law enforcement in traffic matters in Indonesia is in line with the objectives of maqashid al-shari’ah relating to maqashid al-ummah, especially in terms of maintaining stability, security, and justice. Regulations concerning traffic order are matters of the nature of dharuriyyat at this time because the existence of rules regarding traffic will protect matters that are essential in human life, they are religion, soul, mind, descent, and property.Â
The Author in the Age of Mechanical Reproduction Marcel Duchamp's Fountain and the Originality of Replica
No full textIn 1917, Marcel Duchamp chose a mans urinal, signed it R. Mutt 1917," entitled it Fountain, and submitted it for an art exhibition. Although Fountain was rejected, it posed the fundamental questions regarding the nature of art and its authenticity. Fountain was canonized as the groundbreaking practice of Readymade, which changed the course of modem art once and for all. Yet, it is a sheer mystery how this urinal, one of the standardìzed products, mechanically manufactured in a factory to be consumed for everyday needs, was alienated from its initial field of commodity to be de-commiditized, re-valorized, and circulated as a significant work of art, without the material existence of the object and a visible author. For the urinal or Fountain disappeared soon after the rejection-either lost or destroyed. Moreover, since Duchamp kept his authorship a secret, only a handful of people knew that Mr. R. Mutt was in fact Duchamp. In the early 1930s, Duchamp began reproducing his lost original as accurately as possible based on his memory, documentation, and photograph. Although his original work was mechanically produced, the process of reproductions was highly controlled and the outcomes were carefully crafted by the artist. The range of histories of the things functioning as replicas of the lost Fountain reveals the iηtensity of the aspiration of the author to preserve the authenticity of the original and subsequently the authority of the artist by putting thε copies in circulation. By investigating the Fountains reproductions, I argue that bεhind the mystery of Fountain， there exists an author whose power is not activated by his manual labor of production, but by his name, i.e., the signature, in the realm of mass production in the age of mechanical reproduction
`Plural Shar��ah�. A Liberal Interpretation of the Shar��ah Constitutional Clause of the 2014 Egyptian Constitution
No full textThis article addresses the Egyptian Constitution issued in 2014 (dust�r �umh�riyyah mi�r al-�arabiyyah). Article 2 declares that Islam is the religion of the State and that the Shar��ah is the main source of legislation. The aim of the author is to interpret this provision considering the role that the Islamic religion plays in the cultural and legal framework of Arab countries, notably in Egypt. Furthermore, this article tries to develop a pluralistic interpretation of the norm, taking into account some foundational aspects of the Egyptian legal system including the Civil Code of 1948, the particular tradition of Arab Constitutionalism, and the former jurisprudence of the Supreme Constitutional Cour
Analysis of 3.4 Ah lithium-sulfur pouch cells by electrochemical impedance spectroscopy
No full textDespite great progress in lithium-sulfur (Li-S) batteries, the electrochemical reactions in the cell are not yet fully understood. Electrode processes, complex interfaces and internal resistance may be characterized by electrochemical impedance spectroscopy (EIS). EIS is a non-destructive technique and easy to apply, though there are challenges in ensuring the reproducibility of measurements and the interpretation of impedance data. Here, we present the impedance behavior of a 3.4 Ah Li-S pouch cell characterized by EIS. The impedance changes were analyzed over the entire depth-of-discharge, depth-of-charge, and at various temperatures. Based on the formation of intermediates during (dis)charging, the changes of resistances are observed. Overall, the increase in temperature causes a decrease in electrolyte viscosity, lowering the surface energy which can improve the penetration of the electrolyte into the electrode pores. Moreover, the effect of superimposed AC current during EIS measurement was analyzed, and the results show the dependence of the charge transfer resistance on superimposed AC current which was lower compared to steady-state conditions and consents with theory
