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

传统社会向现代社会的过渡常常导致社会冲突,解决冲突的方式不一,其中以改革和革命为主.当改革不足以解决尖锐的社会冲突之时,革命便不可避免,旧制度随之寿终正寝,而由国家实施的改革模式则力主法律的继承性和合理化变化.19-20世纪初的俄国则成为这样两种社会发展模式博弈的舞台.俄国通过革命解决了当时的社会冲突,其革命模式对许多亚非拉国家产生了深远影响.然而,这些采取革命方式解决冲突的国家多以失败告终,不仅未能步入现代化道路,反而使国家陷入混乱状态.现代化进程顺利与否完全取决于其自身的历史条件与外部因素,盲目效仿他人不足取. 相似文献

In this article, we focus on how a variety of illiberal discourses construct a scene for new geopolitical and geocultural imageries of the post-Soviet space, Europe, and Eurasia. Academically, our approach falls into disciplinary niches known as popular geopolitics (when it comes to territories) and biopolitics (when it comes to people). More specifically, we try to see how Russian artistic personalities and public intellectuals contribute to the re-imagination of the post-Soviet space along the lines of Russian illiberal – and largely anti-Western – thinking. Among our protagonists are Valery Gergiev, Iosif Kobzon, Yulia Chicherina, Gleb Kornilov, Ivan Okhlobystin, and Zakhar Prilepin. All of them are important cultural figures who produce cultural justifications for imperial foreign policy in general, and Russia’s annexation of Crimea and de facto occupation of Donbas in particular. Our main argument is that the illiberal imagery of the post-Soviet world drastically reduces the validity of the major pillars of international society, such as state territorial borders, national jurisdictions, citizenship, and legal obligations and commitments. Instead of the rule of law Russian performative illiberalism puts a premium on a series of loosely defined yet foundational for this type of imagery concepts such as patriotism, national spirit and pride, and “natural,” “organic” bonds defining the sense of belonging to Russia as a trans-border political community. 相似文献

This article, written by a Russian cultural historian, analyzes the concept of “ideology” in the work of Clifford Geertz and his role in understanding the figurative nature of ideology as a cultural system. The author compares Geertz's semiotic approach to culture with the semiotics of culture developed by Russian theorists, particularly Yuri Lotman, showing the convergence and divergence of the two different national traditions. This understanding of the nature and functions of ideology opens new possibilities for discussing the tortured relations of ideology and literature, showing the way fiction can affect the formation of ideological systems and influence practical politics. The analysis is illustrated by examples from Russian political life of the 1990s,when revolutionary changes demanded new sets of ideological metaphors that in their turn shaped the direction of events. 相似文献

In river valleys, both human occupation and subsequent preservation of archaeological sites are affected by active landscape
transformation caused by river lateral migration, incision/aggradation cycles and changes of river hydrological regime. In
the middle Vychegda River valley (Northern Russia), there are numerous traces of human presence since the Mesolithic. We exploit
multi-disciplinary archaeological, geomorphological and geochronological approach to elucidate the environmental preferences
of settlements positioning during different epochs of the Holocene. High resolution space image supplemented with data on
alluvial stratigraphy derived from bank exposures and hand cores, as well as 51 radiocarbon dates were used to make the geomorphic
map showing ages of floodplain/terrace segments and palaeochannels. Using this map together with sediment facial interpretation,
position of archaeological sites was analysed in the context of local geomorphic and hydrologic situation. The majority of
archaeological sites and modern settlements are found on terraces at river banks or at oxbow lakes which were well connected
to the river. Few exceptions from this rule may be explained by seasonal character of dwelling functioning, ritual burial
practice or specialization of settlements. Geomorphic situation was used as a background for planning further prospection
of different-age archaeological objects. 相似文献

Studies of home-based telework by women yield mixed results regarding the usefulness of telework in facilitating work–life balance. Most research on the social impacts of home-based telework focuses on workers—employees or self-employed—who deliberately choose that alternative work arrangement. Labour force analysts, however, predict an increase in employer-initiated teleworking. As a case study of the workforce of one large, financial-sector firm in Canada, this article considers the conditions of employment of involuntary teleworkers, those required by their employer to work full-time from a home office. In-depth interviews were co nducted with a sample of 18 female teleworkers working for the case study firm in a professional occupation. Study participants described the advantages and disadvantages of working from home, particularly with regard to spatial and social aspects of locating work in a home setting. The gendered nature of their jobs, and the caring and supportive functions they provide both through their employment and their household responsibilities are seen to support the relocation of their jobs from office to their homes. In many jurisdictions, telework is promoted as a means of giving women more flexibility to balance their paid work with their household responsibilities; the article highlights some of the contradictions involved in moving the workplace into women's homes. 相似文献
