The sexes of most sea urchin species are externally indistinguishable from one another. Where gross sexual dimorphism does exist, it is invariably associated with nonplanktotrophy. In the most extreme examples, female morphology has become modified to create depressions on the test where offspring may be sheltered throughout development. Since a number of the features used for taxonomic classification are lost on fossilization, it can be difficult to recognize fossil individuals as the dimorphic males and females of the same species. In addition, diagnoses of dimorphic taxa commonly concentrate on the striking female traits, hindering identification of the simpler male form. Here, we present an approach based on morphology and crystallographic determination of developmental mode that allows the recognition of the males of marsupiate echinoid taxa. Males of the brooding temnopleurid Pentechinus mirabilis from the Oligocene of Victoria, Australia are described for the first time.  相似文献

In post-conflict politics, forgiveness is as controversial as it is popular. Generally conceived as the overcoming of negative moral emotions such as resentment and anger, forgiveness is, on the one hand, credited with bestowing significant psychological benefits on its practitioners, contributing to processes of interpersonal and societal reconciliation, and avoiding revenge. On the other hand, however, critics warn that rather than helping to address the negative emotions, forgiveness actually helps to provoke resentments and grievances by heaping injustice upon injustice. Herein lies the dilemma with which this article is concerned. By examining the nature of the negative emotions and their relationship to the pursuit of justice, as well as the nature and consequences of forgiveness, it considers the role that victim participation in human rights trials plays in helping post-conflict societies to overcome the forgiveness dilemma. To do so, it focuses on Case 001, heard before the Extraordinary Chambers in the Courts of Cambodia.  相似文献

Since 2006, four maritime archaeology field schools, desktop and field surveys have been carried out in Guam. In 2012 a site associated with the United States Navy's Construction Battalion (US Seabees) was investigated. This paper summarizes the historical background of Guam and the known sites of maritime archaeological interest, particularly those dating to World War II. The problems of public interpretation of the cultural material of colonial powers are considered, and, using the Seabee site as an example, ways in which Guam's indigenous Chamorro people can be included in this history are presented.  相似文献

This article examines how the Japanese Woman's Christian Temperance Union, in the name of promoting liberty and rights of women in their relations with men, constructed hierarchies to ascribe value to themselves through moral condemnation. The JWCTU used extramarital sex as a political issue to strengthen the position of the legal wife in the household as opposed to the concubine and prostitute. Their efforts to prohibit Japanese women from going abroad as prostitutes, while understood as an attempt to end a system of slavery that violated the inherent rights of Japanese womanhood, was actually a desire to regulate the behaviour of the poor. The JWCTU based its moral reform agenda on the importance of premarital chastity, strict monogamy and the obligation to work for the good of the nation. Its construction of prostitution as evil represents an important strand in the history of the relationship between prostitution and family as a socio‐political issue in modern Japan.  相似文献

This article considers the capacity of formal education to undermine established processes of caste and class reproduction in an area of north India, with particular reference to the views and strategies of educated Dalit young men. It draws on quantitative and qualitative research conducted by the authors in a village in Bijnor district, western Uttar Pradesh (UP). We discuss how educated Dalit young men perceive education, how they seek to use educational credentials to obtain ‘respectable’ jobs, and how they react when this strategy fails. Increased formal education has given Dalit young men a sense of dignity and confidence at the village level. However, these men are increasingly unable to convert this ‘cultural capital’ into secure employment. This has created a reproductive crisis which is manifest in an emerging culture of masculine Dalit resentment. In response to this culture, Dalit parents are beginning to withdraw from investing money in young mens’ higher secondary and tertiary‐level education. Without a substantial redistribution in material assets within society, development initiatives focused on formal education are likely to be only partially successful in raising the social standing and economic position of subordinate groups.  相似文献

When Constantine first entered Rome after his defeat of Maxentius in October 312, he encountered a rich and complex Christian community and a bishop whose position was precarious. Centuries of growth and a long religious peace had resulted in the development of a large number of locally based communities in Rome with their own centres of worship - the tituli. Constantine needed to convince these communities of his bona fides as a Christian emperor. The bishop of Rome, Miltiades, was the ruler of a relatively newly unified see, recently fractured by persecution and controversy. Miltiades' relative weakness was to Constantine's political advantage, especially since it made him eager to receive the vast ocean of generosity which Constantine began to pour into the Roman Church. The particular and immediate beneficiary of this generosity was the bishop, who gained a vast and lavishly appointed cathedral, and a palace to go with it.  相似文献
