Certain families of atympanate (deaf) moths are more abundant during the summer at times when bat activity is low. Atympanate moths were collected at ultraviolet lights throughout the summer at a site in southeastern Ontario. Seasonal frequency distributions for individual families showed different trends when compared with ambient bat activity levels. Most saturniids were collected between mid-May and mid-June, before the time when bats are most active (July and August). Lasiocampids were also collected outside the range of high bat activity, emerging in early May, late June, or late August. Population levels of the sphingids, on the other hand, were similar to bat activity levels. From these data, I suggest that some families of deaf moths face reduced selection pressure by bats through temporal isolation.

Mist Net

We evaluated the annual activity cycle of Nytophilus gouldi and N. geoffroyi using 82 nights of mist-netting data from a site near Armidale in northern NSW. Our purpose was to assess whether these bats hibernated or used short bouts of daily torpor combined with foraging on at least some nights. During the cold months of the year (May - August) bat activity levels inferred from net captures was very low providing support for the hypothesis that these bats use daily torpor and at least sometimes actively forage as opposed to entering hibernation.

Relation Approach

The name generator approach and the role relation approach are among the most common ways to measure ego-centered social networks. The name generator approach, which first requires of a respondent to name actual persons and then usually asks several additional questions about these persons gives richer data on the respondent's social network, but is, on the other hand, relatively costly and burdensome. On the other hand the role relation approach is simpler to use and probably less burdensome for the respondent (he/she names persons in his/her networks only in terms of their roles, e.g., partner, friend), but provides less precise data on the respondent's network (e.g., network composition and size). Previous experiments which compared both approaches with regard to network composition (proportions of family, friends, neighbors and co-workers) provide incomplete evidence because the two approaches differed in several methodological aspects (e.g., question wording, limitation of the number of named alters, ranking of named alters). In this article, an experiment was designed in which all factors that were found to interact with network composition and the two approaches were controlled for. Based on previous studies, several hypotheses were formulated and tested. Data were collected on a quota sample of 683 respondents by students at the Faculty of Social Sciences and the Faculty of Arts in Ljubljana in October and November 2008. Results show that, in general, differences in frequency distributions were not large. Provision of instrumental support is similar for both approaches, but larger differences appear in emotional, informational and work support. Differences were greater for strong ties and for the category "no one". Differences were also slightly larger for first choices. Dispersion of roles was slightly greater with the name generator approach. Results are discussed in comparison with previous findings.

Two-step sequential procedures for the Pd-catalyzed synthesis of 5- and 6-azaindoles are reported. The reactions proceed in very good yields. 6-Azaindoles are formed through site-selective Pd-catalyzed Sonogashira reaction of 3,4-dibromopyridine with alkynes, followed by a Pd-catalyzed tandem C–N coupling and cyclization with amines. On the other hand, 5-azaindoles are obtained by a site-selective Pd-catalyzed C–N coupling reaction of 3,4-dibromopyridine with amines, followed by C–C coupling and cyclization with alkynes.

The identification of the lakes of the Cyzicene and the determination of the site of Dascylium, the seat of the Hellespontine satraps, are problems which have worried every scholar who has had to deal with the history or geography of the district. They are inseparable, because not only the names themselves, but also the statements of our ancient authorities, prove that Dascylium involves the neighbourhood of a Dascylite lake, and the Dascylite lake the neighbourhood of a Dascylium. Investigators have generally adopted one of two theories. Those who, like Dr. Richard Kiepert, have started from a place Dascylium, have fixed it at Daskeli or Diaskeli (Yaskil, Eskil Liman), a roadstead and village on the coast midway between Mudania and the Rhyndacus, and have conjured up a vanished lake in the valley of the Ulfer or Nilufer a few miles to the south. Since the publication of Heinrich Kiepert's large map this view has become an accepted tradition, and still holds the field. Those on the other hand who have started from a lake have usually found it in Lake Manyas, 10 or 12 miles south of Panderma, and have cast about for a site for Dascylium in its vicinity. Mr. F. W. Hasluck discusses the problems in his scholarly book on Cyzicus and the country adjacent to it, and regards this latter solution as the more probable of the two, but hazards a conjecture that Dascylium is perhaps to be sought farther eastward near Brussa. Some new evidence which has lately accrued from the recently published Hellenica Oxyrhynchia and from archaeological discoveries justifies a fresh examination of the questions.

Relations Of Power

The notion of the body as “a medium of culture” (Bordo, 1990, p. 13), and specifically the female body as a site on which the oppression of patriarchy is inscribed or played out has been discussed by many feminist theorists (Bartky, 1988; Bordo, 1990; Dimen, 1989). More recently there has been increasing interest in the material body as a source of kinesthetic pleasure rather than, or simultaneously as, a site of inscription and oppression. In searching for new ways to think and talk about the body, there is a recognition that it cannot be seen simply as either a site of oppression or pleasure, but rather as a site where many apparently contradictory and opposing discourses can coexist and where interesting and complex mixes of pleasure and oppression can occur simultaneously (Shilling, 1993).In this paper we attempt to explore these complexities through a study of belly dancing. This is a form of physical activity with an increasingly large following. On one hand, it seems possible to conceive of belly dancing as ‘feminist project’ as it offers possibilities for challenging hegemonic constructions of femininity and for women’s empowerment; on the other hand, many of the practices associated with belly dancing work to construct discourses which sit uncomfortably with feminist understandings of the body. This paper then becomes an exploration of the complex meanings which constitute the contemporary practice of belly dancing, with reference to a specific dance class in a regional city in Australia.While we are using the description ‘feminist project’ as a guiding principle for this paper, we also recognize that this is not a totalizing concept and will be different for different women in different contexts. We also recognize that the attribute “feminist” is itself not unitary but that feminist theory takes many forms, takes up different issues and defines its objects of study in a variety of ways. In the paper we draw on feminist post-structuralist theory to examine the various discourses and social practices of belly dancing. This allows us to recognize that in talking about the dance, the women interviewed may draw on a wide range of discourses which are concerned with women and their bodies, and which in their different ways may be characterized as feminist. On the other hand, the consequences of taking up one discourse rather than another have implications for how women are located and locate themselves in relations of power. We are wary, for instance, of essentializing discourses which attempt to naturalize sexual differences in a context where male and female attributes are often seen as constituting the opposite sides of a binary where those attributes associated with women are regarded as of lesser value.

Allen’s (2011) provocative argument on the difference between topographic and topologic ontologies in human geography offers human geographers an important opportunity to re-engage with other similarly spirited arguments about the limitations of the topographic. For example, debate over Marston et al.’s (2005) argument for a ‘site ontology’ has tended to sidestep the question of topological space and has instead dwelled on whether or not their representation of human geography research on scale is accurate. However, if Allen’s research gives human geographers another opportunity to take up the question of sociospatial practice as contingent, site-specific, and self-structuring, it also poses at least two problems. On the one hand, Allen characterizes the topographic and topologic according to a too neat calendar of sociospatial relations. On the other hand, Allen overlooks a long-standing appreciation for the topologic in human geography by drawing a strong distinction between past and newer intellectual approaches to power and space.

Empirical Material

This essay analyses skin bleaching among middle-class Tanzanian women as performative practice. It draws on empirical material from interviews with middle-class Tanzanian women as well as from advertisements in Dar es Salaam. Skin bleaching is situated at a ‘site of ambivalence’ (Butler), revolving around ‘light beauty’ as postcolonial regulatory ideal. Thus on the one hand, skin bleaching is analyzed as a practice of ‘passing for light(-skinned), embodying urban ‘modern’ forms of subjectivation. On the other hand, the decolonizing potential of skin bleaching becomes apparent as the interviewed women’s forms of embodiment renegotiate postcolonial Blackness putting forward notions of ‘browning’ (Tate). However, ‘light beauty’ then also appears as norm, according to which forms of embodiment can only ‘fail’. In this regard, skin bleaching challenges essentialized notions of Blackness, embodied in the color of one’s skin, while it also illustrates the performativity of racialized embodiment and its intersections with other structural categories.

Experiments were performed with intact human red blood cells to determine whether the inhibitory effects of high Cl- concentrations on Cl- exchange are primarily due to interaction at the cytoplasmic or the external surface of the membrane. When internal Cl- was varied from 150 mM to 600 mM Cl- (using the nystatin technique), keeping external Cl- constant at 150 mM (with sucrose added to maintain osmotic balance), Cl- exchange was inhibited almost exactly as much as when both internal and external Cl- were increased from 150 mM to 600 mM. On the other hand, if internal Cl- was maintained constant at 600 mM, variation of external Cl- (with either sucrose, gluconate, or citrate-sucrose mixtures replacing Cl-) had no consistent effect on Cl- exchange. Even if internal Cl- was kept at 150 mM by substitution of gluconate for Cl-, an increase in external Cl- from 150 mM to 600 mM did not significantly inhibit Cl- exchange. Thus the self-inhibitory effects of Cl- seem to be caused primarily by binding to a site at the cytoplasmic side of the membrane. External Br-, on the other hand, did cause a significant inhibition of Cl- exchange. In contrast to the inhibitory effects of Cl- at neutral pH, at very high pH (around pH 11) there is an activation of Cl- exchange at very high Cl- concentrations. This effect, however, depends on binding of Cl- to an external site. Thus there seem to be at least two different low-affinity Cl- binding sites, one at the cytoplasmic side, which inhibits Cl- exchange, and one at the external side, which activates Cl- exchange at high external pH.

AbstractImplementation of Law No. 13 of 2003 on manpower is interesting to do because the company has violated and does not provide freedom for employees to exercise their religious beliefs. The limitation of worship facilities in the workplace is one of the forms of how the company has no commitment to implementation of the by that have been laid down. The research on freedom of worship of the workers has chosen a place, namely in Bekasi Regency. The purpose of this research is to provide a deep description and understanding of freedom in the conduct of the worship of workers under the Law No. 13 of 2003 on employment in freedom of exercise of religious obligations for the workers in Bekasi regency. This research uses a Quali-tatif method and gives birth to the Keismpulan namely (1) companies that become a site of research in Bekasi has provided the facilities and infrastructure of worship as stipulated Act No. 13 of 2003 on employment in freedom of exercise of religious obligations. Nevertheless, on the other hand, the workers still expect the improvement of the quality and quantity of worship facilities so that it can run the worship more comfortably; and (2) in general, consciousness worships the workers at levels or levels. That is to say, they have faith in God with minimal knowledge of faith. They also carry out religious practices as evidence of the faith itself and as evidence of obedience to God.AbstrakImplementasi Undang-Undang Nomor 13 Tahun 2003 tentang Kete­naga­kerjaan menjadi menarik dilakukan karena kerapkali perusahaan melanggar dan tidak memberikan kebebasan untuk para pegawai dalam menjalankan keyakinan agamanya. Keterba­ta­san sarana ibadah di tempat kerja pun merupakan salah satu bentuk bagaimana perusahaan tidak memiliki komitmen terhadap imple­mentasi atauran yang telah diundang­kan. Penelitian menge­nai kebebasan beribadah kaum pekerja ini memilih tempat, yaitu di Kabupaten Bekasi. Tujuan penelitian ini untuk memberikan deskripsi dan pemahaman secara mendalam mengenai Kebebasan Dalam Menjalankan Beribadah Pekerja Dihubung­kan Undang-Undang Nomor 13 Tahun 2003 tentang Ketenagakerjaan Dalam Kebebasan Menjalankan Kewajiban Beragama Bagi para kaum pekerja di Kabupaten Bekasi. Penelitan ini menggunakan metode kuali­tatif dan melahirkan keismpulan yakni (1) perusahaan-perusahaan yang menjadi tempat penelitan di Kabupaten Bekasi sudah menye­diakan sarana dan prasarana ibadah sebagaimana diatur Undang-Undang Nomor 13 tahun 2003 tentang Ketenaga­kerja­an dalam Kebe­ba­san Men­jalan­kan Kewajiban Beragama. Namun demikian, di sisi lain, para buruh masih mengharapkan per­baikan kualitas dan kuantitas sara­na ibadah sehingga dapat menjalankan ibadah lebih nyaman; dan (2) secara umum, kesa­da­ran beribadah para pekerja berada pada tingkat atau level biasa. Artinya, bahwa benar mereka beriman kepada Allah dengan penge­­tahuan keimanan yang minimal. Mereka juga melak­sana­kan praktik agama sebagai bukti dari keimanan itu sendiri dan sebagai bukti ketaatan kepada Allah.

Metabolic Behavior

In vivo injections of three types of anions (75SeO3=, 75SeO4=, 35SO4=) into rabbits revealed a basic difference between the metabolic behavior of the selenium anions and that of sulfur anion in cartilage; whereas sulfate was incorporated predominantly into glycosaminoglycans, the entry of both selenium ions into this fraction was almost nonexistent. On the other hand, protein and lipid fractions isolated from cartilage had higher activity levels when selenium ions were injected than when sulfate was injected. In cartilage, the selenate activity disappeared at a faster rate than either selenite or sulfate. In blood sera the rate of activity disappearance was higher with both selenate and sulfate than with selenite.
