Export production under exchange rate uncertainty

Given that a multinational enterprise can react flexibly upon exchange rate movements, international trade flows may be interpreted as an option. An enterprise will opt to export if the profits obtained from exporting under given exchange rate developments are greater than if foreign subsidiary sales were opted. Naturally, given negative exchange rate scenario situations, an enterprise will choose not to export. By virtue of a favorable exchange rate situation it may be more advantageous to implement the flexibility given by the inherent option exercise privilege. Interestingly, even taking account of entrepreneurial risk aversion aspects of enterprises, it is demonstrated that situations characterized by enhanced exchange rate volatility may still lead to greater export trade volumes. --Export,Exchange Rate Volatility,Risk Aversion,Real Option

Formazanate coordination compounds:Synthesis, reactivity, and applications

Formazans (Ar1-NH-NCR3-NN-Ar5), a class of nitrogen-rich and highly colored compounds, have been known since the late 1800s and studied more closely since the early 1940s. Their intense color has led to their widespread use as dyes, especially in cell biology where they are most often used to quantitatively assess cell-viability. Despite structural similarities to well-known ligand classes such as β-diketiminates, the deprotonated form of formazans, formazanates, have received relatively little attention in the transition metal and main group coordination chemistry arenas. Formazanate ligands benefit from tunable properties via structural variation, rich optoelectronic properties owing to their highly delocalized π-systems, low-lying frontier orbitals that stabilize otherwise highly reactive species such as radicals, and redox activity and coordinative flexibility that may have significant implications in their future use in catalysis. Here, we review progress in the coordination chemistry of formazanate ligands over the past two decades, with emphasis on the reactivity and applications of the subsequent complexes

The organic crisis of British capitalism and race: the experience of the seventies

Chapter 1 of the "Empire Strikes Back" examines the place of "race" and racism in the political transformation of Britain at the end of the 1970s, and argues that Britain has entered a long-term political and economic crisis which has brought new urgency to the politics of race and nation. The authors argue that the British state is very far from its popular image as a liberal democracy, and all our notions of culture, nation and class are based on deeply racist structures

Die Prinzipal-Agent-Theorie als Erklärungsinstrumentarium von Korruption: Angewendet auf den Praxisfall „Siemens“

Zunehmend wird Korruption aus einem wirtschaftswissenschaftlichen Verständnis betrachtet und erklärt. Als besonders ergiebiges Instrumentarium zur Erklärung von Korruptionsfällen hat sich die Prinzipal-Agent-Theorie bewährt. In diesem Artikel wird die Prinzipal-Agent-Theorie allgemein und theoretisch vorgestellt und anschließend auf den Praxisfall Siemens angewendetKorruptionsprävention im Unternehmen, Prinzipal-Agent-Theorie, Neuen Institutionsökonomik, Siemens Konzern

Ist Fairer Handel Wirklich Fair?

Organisationen des Fairen Handels verfolgen das Ziel benachteiligten Produzenten in Entwicklungsländern faire Preise für deren Erzeugnisse zu zahlen. Dennoch ist es aus makro- und mikroökonomischer Sicht fraglich, ob die Zahlung eines Preisaufschlags wirklich effektiv für die betroffenen Produzenten ist. Am Beispiel des Bananenmarktes soll anhand einer Kosten-Nutzen-Analyse und der Analyse möglicher negativer Externalitäten des Fairen Handels auf nichtteilnehmende Produzenten die Frage erörtert werden, inwieweit dieses alternative Handelsmodell als „fair“ bezeichnet werden kann.Fairer Handel, Bananenmarkt, Kosten-Nutzen-Analyse, Verteilungsaspekte, negative Externalitäten

Implementation of a herd management system with wireless sensor networks

This paper investigates an adaptation of Wireless Sensor Networks (WSNs) to cattle monitoring applications. The proposed solution facilitates the requirement for continuously assessing the condition of individual animals, aggregating and reporting this data to the farm manager. There are several existing approaches to achieving animal monitoring, ranging from using a store and forward mechanism to employing GSM-based techniques; these approaches only provide sporadic information and introduce a considerable cost in staffing and physical hardware. The core of this study is to overcome the aforementioned drawbacks by using alternative cheap, low power consumption sensor nodes capable of providing real-time communication at a reasonable hardware cost. In this paper, both the hardware and software has been designed to provide a solution which can obtain real-time data from dairy cattle whilst conforming to the limitations associated with WSNs implementations

Band-Gap Tuning in Acceptor-Donor-Acceptor Boron Difluoride Formazanates

π-Conjugated molecules with acceptor-donor-acceptor (A-D-A) electronic structures are an important class of materials due to their tunable optoelectronic properties and applications in, for example, organic light-emitting diodes, nonlinear optical devices, and organic solar cells. The frontier molecular orbital energies, and thus band gaps, of these materials can be tuned by varying the donor and acceptor traits and π-electron counts of the structural components. Herein, we report the synthesis and characterization of a series of A-D-A compounds consisting of BF2 formazanates as electron acceptors bridged by a variety of π-conjugated donors. The results, which are supported by DFT calculations, demonstrate rational control of optoelectronic properties and the ability to tune the corresponding band gaps. The narrowest band gaps (EgOpt= 1.38 eV and EgCV= 1.21 eV) were observed when BF2 formazanates and benzodithiophene units were combined. This study provides significant insight into the band-gap engineering of materials derived from BF2 formazanates and will inform their future development as semiconductors for use in organic electronics

Locating the ‘radical’ in 'Shoot the Messenger'

This is the author's accepted manuscript. The final published article is available from the link below, copyright 2013 @ Edinburgh University Press.The 2006 BBC drama Shoot the Messenger is based on the psychological journey of a Black schoolteacher, Joe Pascale, accused of assaulting a Black male pupil. The allegation triggers Joe's mental breakdown which is articulated, through Joe's first-person narration, as a vindictive loathing of Black people. In turn, a range of common stereotypical characterisations and discourses based on a Black culture of hypocrisy, blame and entitlement is presented. The text is therefore laid wide open to a critique of its neo-conservatism and hegemonic narratives of Black Britishness. However, the drama's presentation of Black mental illness suggests that Shoot the Messenger may also be interpreted as a critique of social inequality and the destabilising effects of living with ethnicised social categories. Through an analysis of issues of representation, the article reclaims this controversial text as a radical drama and examines its implications for and within a critical cultural politics of ‘race’ and representation

Sacred communities: contestations and connections

This article discusses a project whose purpose was to review existing qualitative and quantitative data from two separate studies to provide new insights about everyday religion and belonging. Researchers engaged in knowledge exchange and dialogue with new and former research participants, with other researchers involved in similar research, and with wider academic networks beyond the core disciplines represented here, principally anthropology and geography. Key concluding themes related to the ambivalent nature of ‘faith’, connections over place and time, and the contested nature of community. Implicit in terms like ‘faith’, ‘community’, and ‘life course’ are larger interwoven narratives of space, time, place, corporeality, and emotion. The authors found that understanding how places, communities, and faiths differ and intersect requires an understanding of social relatedness and boundaries
