The occurrence of Apatopygus gaudensis sp. nov. in the upper part of the late Oligocene (Chattian) Lower Coralline Limestone division, and the lower part of the early Miocene (probably late Aquitanian) Lower Globigerina Limestone division of the Maltese Islands (Central Mediterranean), is the first confirmed record of Apatopygus outside the Australia-New Zealand region. Apatotygus vincentinus (Tate, 1891) from the middle to late Eocene of southern Australia is the earliest known occurrence of the genus, possibly suggesting that Apatotygus may have evolved earlier in the Australasian region, or merely that it is yet to be discovered in pre-Oligocene strata in the Mediterranean area.  相似文献

Since its discovery and raising offshore of Charleston, Warren Lasch Conservation Center scientists have conducted extensive research on the contents and components of the American Civil War submarine H.L. Hunley, the first successful combat submarine. Recent conservation of the aft ballast pump has led to greater focus on the function and configuration of the ballast system and how it pertains to the submarine's sinking. This article relays the latest interpretation on design and use of the ballast system onboard the Hunley; findings from historical research on the components, operation and design of the aft pump, and avenues for further research. Understanding the ballast system and pump may prove highly relevant in answering questions regarding the loss of the vessel and her crew.  相似文献

The wrought iron suspension footbridge, built in 1824 at the Wissekerke Castle in Kruibeke (Belgium) is the oldest surviving chain footbridge in continental Europe. As the footbridge shifted from private to public use, the condition of the footbridge was surveyed and assessed. During restoration works, which started in the winter of 2011, new construction details were revealed. The original foundation was excavated giving insight into the applied-anchorage system of the suspension cable. The iron bridge was blast-cleaned, revealing not only its connections, but uncovering assembly and production stamps. These new findings not only broaden the insight in the construction of the 1824 Wissekerke footbridge, they also contribute to the overall knowledge of early construction in wrought iron.  相似文献

Abstract:

Early twentieth-century Manila saw the motorisation of its urban transport system. This was a significant transformation not only because of the technological changes it brought about but more importantly because of its role in shaping the highly gendered discourse of colonial modernity. Motorised vehicles, like the streetcar and the automobile, were trumpeted as masculine and modern machines by America’s civilising mission. This colonial discourse was continuously shaped and subverted by a collision of masculinities coming from different directions. This essay will focus on four different male groups in an effort to understand how transport motorisation influenced their sense of masculinity. White American colonisers imagined themselves as modern men destined to bring civilisation to the colony through technology. The native elites used the coloniser as their model by appropriating the symbols of masculine modernity. While the male workers of the modern transport sector gained knowledge of and access to the domains of those in power, those in the traditional sector became targets of vilification by the native and colonial elites. Instead of a duel between two sets of masculinity (coloniser vs. colonised) what emerged was a complex set of relationships influenced by the socioeconomic differences that separated these four groups.  相似文献

In the context of the epistemological and methodological debates about rational choice (RC) sparked by Green and Shapiro and the subsequent rejoinders, Hindmoor made the theoretical claim that there is now an opportunity for RC to be enhanced and for past debates to be set aside by incorporating different theoretical perspectives into RC. This article presents an example of one context in which this can be done: the study of illegal private protection (IPP) produced by organised criminals and corrupt officials. It extends a rational theory of criminal protection to enable the simultaneous analysis of corrupt protection and augments this approach with theories of social capital (SC). Both positive and negative forms and effects of SC are considered. This approach highlights a middle ground between advocates and critics of RC, demonstrating a capacity to explain patterns in the production of IPP between organisations and across countries.

针对格林、沙皮罗与弗里德曼的否定者所发起的有关理性选择的认识论及方法论论战,辛德摩尔提出一个理论主张:现在正可以通过吸纳不同的视角而弘扬理性选择,以往的辩论可置之一旁。本文讨论了一个可行的案例:有组织犯罪分子造成的非法私人保护。作者应用理性理论于犯罪保护,对腐败保护做了分析,并用社会资本理论扩展了这一方法。作者对社会资本理论的正负短长做了分析。这样的研究强调了介于理性选择理论赞同方与反对方的中间地带,展示对于组织间及跨国非法私人保护的产生的解释能力。  相似文献

Parenting has a complex but only recently examined history. This article surveys this scholarship, which is driven by the histories of gender, emotions, medicine, bodies, material culture, class and deviance to uncover how parenting is socially and culturally constructed and therefore changes over time. It traces several significant arguments. First, shifting gender constructions have reshaped expectations about mothers' and fathers' roles. Thus, while paternal breadwinning and maternal care is always important, at times fathers have been commended for caring for infants and mothers for economic provision of offspring. Secondly, the material aspects of life have powerfully affected parenting. Until relatively recently, parents struggled against implacably high rates of infant and child mortality: nursing children, preparing them for death and the afterlife, and coping with grief. Therefore, although the depth of feeling over this remained consistent, varying emotional regimes have influenced forms of parental expression and practice. Parents' responsibilities for their children's health at times of inadequate medical treatment often left them physically and mentally exhausted and woefully disempowered. Other limitations or freedoms were imposed on mothering and fathering by the objects and spaces associated with bringing up children. Thirdly, levels of wealth and social class affect parenting, with working‐class, poor and lone parents especially vulnerable to family disruption due to poverty, ill‐health and under‐ or unemployment. Fourthly, the parameters of bad parenting shift over time, and even those mothers and fathers who killed their children were viewed differently over time and place as cultural sensibilities shifted. Finally, the article concludes with some suggestions for the further development of this exciting new field.  相似文献
