Disrupting the market for illegal rhino horn and ivory

This paper considers methods for regulating the trafficking of rhino horn and ivory, seen through the lens of compliance theories. It stresses the importance of the distinction between normative and instrumental motivations. It argues for a balanced set of strategies that include normative levers designed to change the behaviour of poachers, traffickers and consumers of these products. In particular it considers the options needed to achieve demand reduction in consumer countries, and those needed to provide incentives to local communities in producer countries to disengage from poaching.

Evidence from neurolinguistic methodologies: can it actually inform linguistic/ language acquisition theories and translate to evidence-based applications?

This special issue is a testament to the recent burgeoning interest by theoretical linguists, language acquisitionists and teaching practitioners in the neuroscience of language. It offers a highly valuable, state-of-the-art overview of the neurophysiological methods that are currently being applied to questions in the field of second language (L2) acquisition, teaching and processing. Research in the area of neurolinguistics has developed dramatically in the past twenty years, providing a wealth of exciting findings, many of which are discussed in the papers in this volume. The goal of this commentary is twofold. The first is to critically assess the current state of neurolinguistic data from the point of view of language acquisition and processing—informed by the papers that comprise this special issue and the literature as a whole—pondering how the neuroscience of language/processing might inform us with respect to linguistic and language acquisition theories. The second goal is to offer some links from implications of exploring the first goal towards informing language teachers and the creation of linguistically and neurolinguistically-informed evidence-based pedagogies for non-native language teaching.

Sexual System, Sex Ratio, and Group Living in the Shrimp Thor amboinensis (De Man): Relevance to Resource-Monopolization and Sex-Allocation Theories

The sexual system of the symbiotic shrimp Thor amboinensis is described, along with observations on sex ratio and host-use pattern of different populations. We used a comprehensive approach to elucidate the previously unknown sexual system of this shrimp. Dissections, scanning electron microscopy, size-frequency distribution analysis, and laboratory observations demonstrated that T amboinensis is a protandric hermaphrodite: shrimp first mature as males and change into females later in life. Thor amboinensis inhabited the large and structurally heterogeneous sea anemone Stichoclactyla helianthus in large groups (up to 11 individuals) more frequently than expected by chance alone. Groups exhibited no particularly complex social structure and showed male-biased sex ratios more frequently than expected by chance alone. The adult sex ratio was male-biased in the four separate populations studied, one of them being thousands of kilometers apart from the others. This study supports predictions central to theories of resource monopolization and sex allocation. Dissections demonstrated that unusually large males were parasitized by an undescribed species of isopod (family Entoniscidae). Infestation rates were similarly low in both sexes (approximate to 11%-12%). The available information suggests that T. amboinensis uses pure search promiscuity as a mating system. This hypothesis needs to be formally tested with mating behavior observations and field measurements on the movement pattern of both sexes of the species. Further detailed studies on the lifestyle and sexual system of all the species within this genus and the development of a molecular phylogeny are necessary to elucidate the evolutionary history of gender expression in the genus Thor.

Spontaneous breaking of superconformal invariance in (2+1) D supersymmetric Chern-Simons-matter theories in the large N limit

In this work we study the spontaneous breaking of superconformal and gauge invariances in the Abelian N = 1,2 three-dimensional supersymmetric Chern-Simons-matter (SCSM) theories in a large N flavor limit. We compute the Kahlerian effective superpotential at subleading order in 1/N and show that the Coleman-Weinberg mechanism is responsible for the dynamical generation of a mass scale in the N = 1 model. This effect appears due to two-loop diagrams that are logarithmic divergent. We also show that the Coleman-Weinberg mechanism fails when we lift from the N = 1 to the N = 2 SCSM model.

On the effective potential in higher-derivatives superfield theories

we study the one-loop quantum corrections for higher-derivative superfield theories, generalizing the approach for calculating the superfield effective potential. In particular, we calculate the effective potential for two versions of higher-derivative chiral superfield models. We point out that the equivalence of the higher-derivative theory for the chiral superfield and the one without higher derivatives but with an extended number of chiral superfields occurs only when the mass term is contained in the general Lagrangian. The presence of divergences can be taken as an indication of that equivalence. (C) 2009 Elsevier B.V. All rights reserved.

Torsion theories induced from commutative subalgebras

We begin a study of torsion theories for representations of finitely generated algebras U over a field containing a finitely generated commutative Harish-Chandra subalgebra Gamma. This is an important class of associative algebras, which includes all finite W-algebras of type A over an algebraically closed field of characteristic zero, in particular, the universal enveloping algebra of gl(n) (or sl(n)) for all n. We show that any Gamma-torsion theory defined by the coheight of the prime ideals of Gamma is liftable to U. Moreover, for any simple U-module M, all associated prime ideals of M in Spec Gamma have the same coheight. Hence, the coheight of these associated prime ideals is an invariant of a given simple U-module. This implies the stratification of the category of U-modules controlled by the coheight of the associated prime ideals of Gamma. Our approach can be viewed as a generalization of the classical paper by Block (1981) [4]; it allows, in particular, to study representations of gl(n) beyond the classical category of weight or generalized weight modules.

A Discussion of Globalization Theories - Through International Consumer Perceptions

Globalization has developed more and more within the business world as well as private life during the last decades. Globalization has influenced the way companies are conducting business and their approach towards the consumers which can have an influence on their way of purchasing. Consumers nowadays have more than ever the possibility to get involved and gather experiences from abroad, as well as companies are taking advantage of this globalization. Within this thesis the following question will be discussed: Do consumers see the value companies try to create for them with an identical offer the same way in different markets? This idea is based on Theodore Levitt’s theory of globalization which comprises standardization of an offer since consumer needs are homogenizing globally. Douglas & Wind instead state that segmentation with adaptations is necessary to fulfill all consumer needs. Within this elaboration the question whether standardization is accepted and liked by the consumers is discussed and analyzed by including an empirical research. This research is based on Zeithaml’s model of the Perceived Quality Components, which was the fundamental base behind formulating the survey questions. These were submitted in Germany, the Republic of Ireland and Sweden to be able to discuss and visualize how the consumers of these different markets perceive different aspects of a company’s offer. One particular company, which is seen as doing business globally, was chosen as a test object. Based on the test object Lidl - which consumers were questioned about in the survey - it was possible to conduct a comparison of consumers’ general expectations against components of Lidl’s offer such as price, weekly specials, product range, etc. where differences and similarities between the three countries of Lidl’s fulfillment of these expectations were achieved. They were analyzed to discover to which extent globalization is present. Resulting from the comparison it was concluded that nowadays segmentation is important but developing with time globalization seems to increase in significance. Recommendations for further research about topics which were omitted due to limited resources are presented.

Recensionernas retorik : Om könsroller i kulturjournalistiken

At the centre of this study lies the question if normative gender thinking affects the way poetry gets reviewed and how the reviews are written, this in relation to both the gender of the reviewer and the poet. The study crosses three academic fields; gender studies, poetry and journalism, and is based on the cultural studies theory of media affecting and even creating the world around it. The study is based on two types of analysis. One quantitative analysis based on the thematic criticism theory about detail studies that shows bigger patterns, this analysis focuses on how the poet and his/hers work are being treated in the reviews in areas such as how much space they´re given in the newspapers, how they are named by the reviewer and the tendency to quote the reviewed work.  And one qualitative analysis based on the new criticism method of close reading, that focuses on the reviewers way of writing and how that may be connected with theories of gender differences, this both connected to the gender of the reviewers and the poets. The material chosen for this study are all the reviews that were published in the same newspapers and that reviewed two specific poetry works by two specific poets chosen with great sensibility to age and career so that their difference in gender would be the most significant difference between them. The works were chosen based on year of publishing, they were supposed to be published as newly as possible and as close to each other in time as possible. The works I ended up with were Dimman av allt (2001) and Svart som silver (2008) by Bruno K. Öijer and Silverskåp (2000) and Nu försvinner vi eller ingår (2007) by Birgitta Lillpers. The results of this study show several differences in how poetry is being judged and how poetry reviews are being written are connected with the gender of the poets and the reviewer. Lillpers got 35% less space in the newspapers and Öijers poetry got quoted a lot more which confirms that female poetry often is considered as less important than the male poetry, and that men in general tends to be judged as more professional than woman. The male reviewers tended to express themselves with greater certainty than the female reviewers who held a more professional tone in their reviews and focused more on the technical aspects of the poetry. This confirms the theory of the male words are being looked upon as the truth but contradicts the theory of women writing more based on personal experience and of women being less skilled in language techniques. In conclusion, there are differences in how poetry gets reviewed and how the reviews are written that are connected to the genders of the poet and the reviewer but these differences are complex and does not show a clear normative way of thinking about gender
