Biogeographers, ecologists, palaeontologists, and conservation managers often deal with checklists in which not all individuals have been identified to a species level, or the accuracy of species identification is questionable. Is it possible and credible to investigate species richness based on such checklists? Studies on macrofauna in the Far Eastern seas, eastern Arctic seas, and adjacent waters of the Pacific and Arctic Oceans suggest that in different habitats and for diverse taxa, species, and higher taxa richness strongly correlate with each other and increase with an expansion in the study area and sample size according to the species–area law. Such an increase is higher in the bottom zone than in the pelagic. Species and higher taxa richness also show a decrease from lower to higher latitudes, which is in line with the Humboldt–Wallace’s law. According to Willis’ law and self-similarity in the organisation of taxonomic levels, species richness can be assessed based on the genus, family, and order richness. In other words, supraspecies richness itself can tell us the same as species richness and therefore certain global patterns revealed at the species level may also be revealed at the supraspecies level. Such a concordance in general trends among richness parameters at different taxonomic levels in practice implies that species richness can be studied based on lists that lack species identifications or lists with doubtful species identification. We suggest bolder use of supraspecies richness in science and practice, discussing the disadvantages and advantages of this approach.  相似文献

When the National-Socialists started their restrictive measures against Jewish civil servants and professionals in 1933, they caused a wave of emigration only to be surpassed by the one following the Anschluß of Austria and the ‘November pogrom’ in 1938. Due to their great number, jewish doctors were to become the main object of Nazi persecution in the professional group. Up until 1935 Palestine was their main destination of immigration. In 1935 the British Mandatory Government passed a numerus clausus which mainly cut down the licensing of newly arrived doctors. The article deals with the social problems caused by the mass immigration of a highly qualified professional group in Palestine and with the fight against the restrictive measures of the mandatory Government. A short retrospective glance is cast at the situation in Palestine before 1933. Finally an outlook is given at the impact of this immigration on the health system in Israel.  相似文献

Do social protests affect government housing-related decisions? If so, in what way? To answer this question this study examines the influence of Israel's 2011 social protest on the government's housing policy, using an empirical cumulative-aggregative analysis of housing-related decisions over the past two decades. The empirical analysis is based on two generic classifications of government interventions commonly used in housing literature: first, decisions aimed at increasing the housing stock (supply-side), as opposed to policies aimed at augmenting consumers' financial capacity to obtain adequate housing (demand-side); and second, decisions that encourage homeownership as opposed to those that promote rental housing. The research findings show that the 2011 social protest definitely affected Israel's housing policy, because it prompted the government to engage in housing. However, the interventions introduced focused largely on increasing the inventory of housing units (supply-side) for homeownership and benefited mainly members of the middle class who qualify for mortgages and investors. Thus, despite the increase in government involvement in the post-protest period, Israel's housing policy has remained neoliberal, though in an advanced form of neoliberalism that combines market-oriented policies with centralized tendencies, which we call “centralized neoliberalism.” The study discusses the findings and their implications for various population groups. Given the current global affordable-housing crisis, the findings are relevant to many countries whose existing neoliberal housing policy is failing to address housing-market problems and challenges.  相似文献

This article examines the intense debates over the New Criminal Code of Great Qing (Da-Qing xin xinglü) in the National Assembly (Zizheng yuan) during the Qing empire’s New Policy Reform (1901–11). The focus is on the conflict between those who drafted and supported the new code and those who expressed reservations, especially over reform of the laws on filial piety and fornication. The issue of reconfiguring the family and social order through law was closely related to the overarching agenda of twentieth century legal reform in China—making an empire that “ruled through the principle of filial piety” into a modern nation-state that had direct relationships with its citizens. More importantly, an analysis of the late Qing debate over family law enables this article to problematize such concepts as “Chinese” and “Western” during this crucial moment of China’s empire-to-nation transformation. It showcases the paradox of China’s modern-era reforms—a contradiction between imposing Western-inspired order with a largely indigenous logic and maintaining existing sociopolitical order in the name of preserving national identity.  相似文献

Geographical distance constitutes friction in searching for research collaborators. Taking advantage of a quasinatural experiment featured by High-Speed Railway (HSR) lines in China, this paper employs the difference-in-differences model to identify the causal impact of a substantial improvement in the intercity transportation infrastructure on collaborative innovation across cities. The data pertain to a universe of patent applications filed by Chinese universities and their citations. We find that HSR contributes to a substantial increase in the innovation quantity and quality of collaborative patenting innovation between universities and corporates. It contributes to industry collaboration by utilizing university academic disciplines in the related technology fields. Lastly, HSR facilitates universities to search for new research partners with better quality beyond the geographical boundary.  相似文献

The article explores the role of state-owned enterprises (SOEs) in the globalisation of China's infrastructure capital. Examining how accumulation strategies of Chinese SOEs are driven by a complex set of political and economic, state and private, interests, it foregrounds the inherently hybrid nature of China's state capitalism. We use Kenya's Standard Gauge Railway (SGR) as a case study to analyse how state infrastructure capital traverses borders, and the specific ways that contradictions of accumulation in China are relocated through the improvised hybridity of SOEs. In Kenya, China Road and Bridge Corporation, the main SGR contractor, shifted and adapted its strategies as the pursuit of economic productivity gave way to political priorities in China, simultaneously responding to changing socio-political circumstances in Kenya and across East Africa. Analysing these dynamics, we highlight the contingencies of, and limitations to, structural reorganisation of actually existing forms of state capitalism in China and beyond.  相似文献

Israeli plans to partially annex West Bank territory have mainly been perceived as frustrating the two-state solution, and as putting Palestine/Israel on a path leading to the one-state alternative. This paper analyses partial annexation plans without assuming that the future of Palestine/Israel would necessarily abide by either statist resolution. It argues that by ostensibly distancing Israel's hold of the West Bank from an identifiable configuration of a belligerent occupation, partial annexation is offered to Jewish Israelis as a path for detaching the futurity of the two nations, and as a trajectory for normalising the Israeli state, without having to make what much of this public would see as painful concessions. It further explores settlers’ objections to such plans, claiming that even a partial incorporation of West Bank territory into formal Israel is expected to erode the exclusivity of Jewish domination which Israel has been upholding in its settler-colonial frontier.  相似文献
