This paper analyses corporate and government strategies during the purchase, period of control and divestment by BMW of the car manufacturer Rover over the period 1994 to 2000. This paper examines three types of ‘failure’. It views BMW’s purchase of Rover as a ‘corporate failure’, with British Aerospace keen to sell Rover to raise cash and with BMW not realising the real condition of Rover. It then moves on to examine BMW’s ‘divide and rule’ strategies with regard to working conditions and subsidy-seeking and its decision to sell Rover as an example of ‘strategic failure’. Finally, it considers the ‘hands-off’ nature of British policy towards such transnational firms, and BMW in particular, as an example of ‘government failure’. This paper concludes by raising the possibility of an EU-wide policy towards transnationals, especially in terms of monitoring the activities of such firms.

Optical fibre based sensors are transforming industry by permitting monitoring in hitherto inaccessible environments or measurement approaches that cannot be reproduced using conventional electronic sensors. A multitude of techniques have been developed to render the fibres sensitive to a wide range of parameters including: temperature, strain, pressure (static and dynamic), acceleration, rotation, gas type, and specific biochemical species. Constructed entirely of glass or polymer material, optical fibre devices like fibre gratings offer the properties: low loss, dielectric construction, small size, multiplexing, and so on [1-3]. In this paper, the authors will show the latest developing industrial applications, using polymer optical fibre (POF) devices, and comparing their performance with silica optical fibre devices. The authors address two pressing commercial requirements. The first concerns the monitoring of fuel level in civil aircraft. There is a strong motivation in the aerospace industry to move away from electrical sensors, especially in the fuel system. This is driven by the need to eliminate potential ignition hazards, the desire to reduce cabling weight and the need to mitigate the effects of lightning strikes in aircraft where the conventional metallic skin is increasingly being replaced by composite materials. In this case, the authors have developed pressure sensors based on a diaphragm in which a polymer fibre Bragg grating (POFBG) has been embedded [3]. These devices provide high pressure sensitivity enabling level measurement in the mm range. Also, it has developed an approach incorporating several such sensors which can compensate for temperature drifts and is insensitive to fluid density. Compared with silica fibre-based sensors, their performance is highly enhanced. Initial results have attracted the interest of Airbus from UK, who is keen to explore the potential of optical technology in commercial aircraft. The second concerns the monitoring of acoustic signals and vibration in the subsea environment, for applications in geophysical surveying and security (detection of unwanted craft or personnel). There is strong motivation to move away from electrical sensors due to the bulk of the sensor and associated cabling and the impossibility of monitoring over large distances without electrical amplification. Optical approaches like optical hydrophones [5] offer a means of overcoming these difficulties. In collaboration with Kongsberg from Norway, the authors will exploit the sensitivity improvements possible by using POF instead of silica fibre. These improvements will arise as a result of the much more compliant nature of POF compared to silica fibre (3 GPa vs 72 GPa, respectively). Essentially, and despite the strain sensitivity of silica and POFBGs being very similar, this renders the POF much more sensitive to the applied stress resulting from acoustic signals or vibration. An alternative way of viewing this is that the POF is better impedance-matched to the surrounding environment (water for the intended applications), because although its impedance is higher than that of water, it is nearly an order of magnitude smaller than that of silica. Finally, other future industrial applications will be presented and discussed, showing the vast range of the optical fiber devices in sensing applications.

A tanulmány azt a kérdést vizsgálja, hogy versenyeznek-e az európai kormányok gázolajra vonatkozó jövedékiadó-kulcsaikkal a nagyobb adóbevételekért, és ha igen, befolyásolja-e az országok mérete kormányaik adóztatási stratégiáját. Az üzemanyagturizmussal szembesülő kormányok adókivetési magatartását egy kétországos adóverseny modellel jelezzük előre, amelyben a standard modellektől eltérően a fogyasztók kereslete árrugalmas. Megmutatjuk, hogy ha a kereslet nem teljesen rugalmatlan, mint Nielsen [2001], illetve Kanbur-Keen [1993] modelljeiben, akkor a nagy ország kormányának egyensúlyi viselkedése nemcsak abban különbözik a kicsiétől, hogy nagyobb adót állapít meg, hanem abban is, hogy válaszfüggvénye meredekebb. Az aszimmetrikus adóverseny általunk használt modelljét a dízelüzemanyagoknak 16 európai ország 1978 és 2005 közötti jövedékiadó-adatain vizsgáljuk. Az 1995 és 2005 közötti időszakra vonatkozó becslési eredményeink megerősítik, hogy az európai országok szomszédaik adókulcs-változtatásának hatására változtattak saját adókulcsaikon, és hogy a területileg/gazdaságilag kisebb országok kisebb intenzitással reagáltak szomszédaik adóváltoztatásra, mint a nagyobbak. Tanulmányunk ezzel magyarázatot nyújt arra is, hogy miért erősödött fel a tagállamok jövedéki adókulcsainak méret szerinti differenciálódása az elmúlt bő tíz évben, valamint hogy miért nem sikerült az Európai Uniónak a minimumadószintre vonatkozó előírásával előbbre lépnie az egységes adóztatás megvalósításában. / === / The paper assesses spatial competition in diesel taxation among European governments. By adding an extension to the standard model, it is shown that asymmetric competition – small countries undercutting large – implies that small countries respond less strongly to tax changes by their neighbours than large countries do. An estimate is then made of the fiscal reaction functions for national governments, employing a first-difference regression model with a weighting scheme constructed from road-traffic density data at national borders. Data from 16 countries (EU-15 minus Greece plus Norway and Switzerland) between 1978 and 2005 provides evidence that European governments set their diesel tax interdependently, and moreover, that small European countries tend to react less strongly to changes in their competitors' tax rate than large countries do.

Isla del Coco (Cocos Island) is a small volcanic island located in the Pacific 500 km west of Costa Rica. Three collecting trips to Isla del Coco, in addition to herbarium research, were completed in order to assess the floristic diversity of the island. The current flora of Isla del Coco contains 262 plant species of which 37 (19.4%) are endemic. This study reports 58 species as new to the island. Seventy-one species (27.1%) were identified as introduced by humans. In addition, five potentially invasive plant species are identified. Seven vegetation types are identified on the island: bayshore, coastal cliff, riparian, low elevation humid forest, high elevation cloud forest, landslide and islet. ^ The biogeographic affinities of the native and endemic species are with Central America/northern South America and to a lesser extent, the Caribbean. Endemic species in the genus Epidendrum were investigated to determine whether an insular radiation event had produced two species found on Isla del Coco. Phylogenetic analysis of the internal transcribed spacer (ITS) of nuclear ribosomal DNA was not able to disprove that the endemic species in this genus are not sister species. Molecular biogeographic analyses of ITS sequence data determined that the Isla del Coco endemic species in the genera Epidendrum, Pilea and Psychotria are most closely related to Central American/northern South American taxa. No biogeographical links were found between the floras of Isla del Coco and the Galápagos Islands. ^ The native and endemic plant diversity of Isla del Coco is threatened with habitat degradation by introduced pigs and deer, and to a lesser extent, by exotic plant species. The IUCN Red List and RAREplants criteria were used to assess the extinction threat for the 37 endemic plant taxa found on the island. All of the endemic species are considered threatened with extinction at the Critically Endangered (CR) by the IUCN criteria or either CR or Endangered (EN) using RAREplants methodology. ^

A global corporation values both profitability and social acceptance; its units mutually negotiate governance and represent a highly interdependent network where centers of excellence and high-potential employees are identified regardless of geographic locations. These companies try to build geocentric, or “world oriented” (Marquardt, 1999, p. 20), organizational cultures. Such culture “transcends cultural differences and establishes ‘beacons’ – values and attitudes – that are comprehensive and compelling” (Kets de Vries & Florent-Treacy, 2002, p. 299) for all employees, regardless of their national origins. Creating a geocentric organizational culture involves transforming each employee’s mindset, beliefs, and behaviors so that he/she can become “a world citizen in spite of having a national identity” (Marquardt, 1999, p. 47). The purpose of this phenomenological study was to explore how employees with different national identities experience a geocentric organizational culture of a global corporation. Phenomenological research aims to understand “how people experience some phenomenon—how they perceive it, describe it, feel about it, judge it, remember it, make sense of it, and talk about it with others” (Patton, 2002, p. 104). Twelve participants were selected using criteria, convenience, and snow-ball sampling strategies. A semi-structured interview guide was used to collect data. Data were analyzed inductively, using Moustakas’s (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data. The participants in this study experienced a geocentric organizational culture of a global corporation as on in which they felt connected, valued, and growing personally and professionally. The participants felt connected to the companies via business goals and social responsibility. The participants felt valued by the company because their creativity was welcomed and they could contribute to the corporation certain unique knowledge of the culture and language of their native countries. The participants felt growing personally and professionally due to the professional development opportunities, cross-cultural awareness, and perspective consciousness. Based on the findings from this study, a model of a geocentric organizational culture of a global corporation: An employee perspective is proposed. Implications for research and practice conclude this study.

Mentoring is defined as an "intense caring relationship in which persons with more experience work with less experienced persons to promote both professional and personal development" (Caffarella, 1992, p. 38). It is "a powerful emotional, and passionate interaction whereby the mentor and protégé experience...intellectual growth and development" (Galbraith & Zelenak, 1991, p. 126). In cross-cultural mentoring, mentors and protégés from different cultures confront social and cultural identities, goals, expectations, values, and beliefs (Cross & Lincoln, 2005) to "achieve a higher level of potency in education and society" (Mullen, 2005, p. 6). Cross-cultural mentoring research explores attitudes, behaviors, linguistics and motivators of the more visible racial and ethnic groups in the U.S. (Elmer, 1986, Ulmer, 2008). The cross-cultural mentoring experiences of Indo-Caribbeans in the U.S. are obscured from the research despite their rich socio-historic culture. The purpose of this phenomenological study was to explore the perceptions of Indo-Caribbean protégés regarding the effects of their cross-cultural mentoring experiences in the United States. Phenomenology is "the systematic attempt to uncover and describe...the internal meaning structures, of lived experience [by studying the] particulars or instances as they are encountered" (Van Manen, 1990, p. 10). Criterion and snowball sampling were used to recruit 15 participants. A semi-structured interview guide was used to gather data and Creswell's (2007) simplified version of Moustakas's (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data was used to analyze the data. Three themes emerged: (a) "Sitting at the feet of gurus" taught protégés how to accept guidance, (b) Guru-Shishya: Learning and Discipleship, ways that protégés perceived mentors' guidance related to work, skill acquisition, and social or emotional support, and (c) Samavartan sanskar: Building Coherence, helped protégés understand, manage and find meaning. Protégés' goals and professional expectations determined what they wanted from cross-cultural mentoring relationships and what they were willing to endure within those relationships. Since participants valued achievement and continuous improvement, mentor support was integral to making meaning and developing a sense of coherence in their lives. Implications regarding cross-cultural mentoring relationships together with recommendations for future research conclude the study.

This phenomenological study explored how HR professionals who identified themselves as facilitators of strategic HRD (SHRD) perceived the experience of being an organizational agent-downsizing survivor. Criterion and snowball sampling were used to recruit 15 participants for this study. A semi-structured interview guide was used to interview participants. Creswell's (2007) simplified version of Moustakas's (1994) Modification of the Stevick-Colaizzi-Keen Method of Analysis of Phenomenological Data was used to analyze the data. Four main themes and corresponding sub-themes emerged from an inductive data analysis. The four main themes were a) the emotionality of downsizing, b) feeling responsible, c) choice and control, and d) possibilities for growth. Participants perceived downsizing as an emotional organizational change event that required them to manage their own emotions while helping others do the same. They performed their roles within an organizational atmosphere that was perceived as chaotic and filled with apprehension, shock, and a sense of ongoing loss, sadness and grieving. They sometimes experienced guilt and doubt and felt deceptive for having to keep secrets from others when planning for downsizing. Participants felt a strong sense of responsibility to protect employees emotionally, balance employee and organizational interests, and try to ensure the best outcomes for both. Often being there for others meant that they put on their games faces and took care of themselves last. Participants spoke of the importance of choosing one's attitude, being proactive rather than reactive, and finding ways to regain control in the midst of organizational crisis. They also perceived that although downsizing was emotionally difficult to go through that it provided possibilities for self, employee, and organizational growth.

This report presents the preliminary results of the study of rocks and sediments obtained by dredging during four cruises of the R/V Jean Charcot and R/V Le Suroit during a cooperative program between CNEXO and CEPM (CH 58: April 1975; SU 01: December 1975; CH 66: February 1976; and CH 67: March 1976). Several dredges on the continental slope of the Goban Spur recovered "granitic" rocks on two morphological structures, Granite Cliff and "Menez Bihan" (Pautot et al., 1976), in water depths ranging from 3200 to 4200 meters. According to the radiometric age and petrology, the granodiorite appears to have a close affinity with similar igneous facies which have been described in Iberia (Capdevilla et al., 1973) and attributed to the Variscan intrusive episode which is also found in the nearby continental area (southwest Great Britain and Brittany, France). They often are coated by a centimeter-thick layer of ferromanganiferous deposits (Shaaf et al., 1977).

The natural and anthropogenic changes that are occurring at the coastal zone around the world represent the greatest problem to society in this century. This problem becomes more evident due to high density of coastal cities, to growing tourist-estate speculation of those areas and to climate change that tend to trigger and accelerate the erosive processes that operating in the littoral. In this context, it‟s possible perceive ever more a significant increase of problems associated to the coastal erosion and retreat of cliffs in the state of Rio Grande do Norte, where this study area of this search is located. The area is located in the coastal zone of the city of Baía Formosa/RN, in south-eastern coast of Rio Grande do Norte, and has a extension of about 1200 meters along the Porto beach. The main objective of this study is to analyze the stability of these cliffs in this region. Through field investigations, testings and computational analysis using the Finite Element Method and Equilibrium Limit Methods. The area was divided into four sections, and were applied checklists, and also realized characterization tests and direct shear tests with materials obtained along these sections. In this manner, it was found that the segments of cliff in this coastal zone have heights around 4 meters to 14 meters and inclinations of approximately 40° to 90°.However the constituents soils of the cliffs were classified, in general terms in accordance to Unified Soil Classification System (USCS), as clayey sands or silty sands, clays of low plasticity, clayey gravels and poorly graduaded sands. The most variegated and clayey soils belong to base of the cliff. The stability analysis showed that the safety factors ranged in section 01, from 1.92 to 4.93, in the section 02, from 1.00 to 1.43, in the section 03, from 1.36 to 1.75 , and section 04, from 1.00 to 3.64. Thus, the sections 02 and 03 were considered more unstable. However, the section 03 can be considered as the most critical section due to the absence of coastal protection structures and the narrow strip of beach.

This research starts from the presupposition that Cartilha do Silêncio(1997), a novel by the Brazilian writer Francisco Dantas, has a double articulated shift. One of the moves is towards the modern experience, with the idea that modernity is filled with contraries, as remarked by Nietzsche; the other is linked to the livelihoods ashore on traditional experiences, which encompasses the notion of memory as individual and collective ownership. The aim here is to analyze such perspective, social and critical issues within the characters' life stories that regards the calling of past as clear example that tradition is not gone, though modern life presents its own signs. Such dynamics gives to the plot a paradoxal feature. This work is mainly grounded on Marshall Berman' s thoughts in All That Is Solid Melts Into Air: The Experience of Modernity (1982) as well as on Antoine Compagnon'sFive Paradoxes of Modernity (1994). Assuming that Francisco Dantas' Novel is set as a split narrative, outcome of social memory originated on individual experiences aside social process and patriarchal family, this research brings into play the concept of memory by Jacques Le Goff in History and Memory (1992) along EcléaBosi's study in Memória e Sociedade: lembranças de velhos (1979). Keen to check how Cartilha do silêncio adjoins modern livelihoods with aesthetics order, the method articulates text and context, literary and social life, according to Antonio Candido'sLiteratura e Sociedade (1965). Thus, after reading the novel, it is possible to notice how the identity of the characters are built throughout the plot and it is also kept against settling on its social context during the transition from patriarchal tradition to modernity, creating a taut mood between both registries.

The coastline from Rio Grande do Norte state is characterized for the presence of dunes and cliffs. The latter consist of slopes with height up to 40 meters and inclinations ranging from 30° to 90° wich horizontal. Thus, this dissertation had as objective the evaluation of the stability of cliff from Ponta do Pirambu in Tibau do Sul/RN, and the realization of a parametric study on the stability of a homogeneous cliff considering as variables the material's cohesion, the cliff height and the slope inclination. The study in Ponta do Pirambu considered yet the possibility of the existence of a colluvial cover with thickness ranging from 0.50 to 5.00 meters. The analyzes were performed by Bishop method, using GEO5 software. In parametric analysis were produced graphics that relate height cliff with the inclination, to safety factors equals to 1.00 and 1.50; besides graphics where it is possible easily get the lowest safety factor as from the cohesion, cliff height and its inclination. It was concluded that these graphs are very useful to preliminary analyzes, for the definition of critical areas in risk mappings in areas of cliffs and for determination of an equation for obtaining the lowest safety factor function of the strength parameters and of slope geometry. Regarding the cliff from Ponta do Pirambu, the results showed that the cliff is subject to superficial landslides located in the points where may there be the presence of colluvium with thicknesses greater than two meters. However, the cliff remains stable presenting the global safety factor equal or superior to 2.50 in the saturated condition.

This dissertation consists of three distinct components: (1) “Double Rainbow,” a notated composition for an acoustic ensemble of 10 instruments, ca. 36 minutes. (2) “Appalachiana”, a fixed-media composition for electro-acoustic music and video, ca. 30 minutes, and (3) “'The Invisible Mass': Exploring Compositional Technique in Alfred Schnittke’s Second Symphony”, an analytical article.

(1) Double Rainbow is a ca. 36 minute composition in four movements scored for 10 instruments: flute, Bb clarinet (doubling on bass clarinet), tenor saxophone (doubling on alto saxophone), french horn, percussion (glockenspiel, vibraphone, wood block, 3 toms, snare drum, bass drum, suspended cymbal), piano, violin, viola, cello, and double bass. Each of the four movements of the piece explore their own distinct character and set of compositional goals. The piece is presented as a musical score and as a recording, which was extensively treated in post-production.

(2) Appalachiana, is a ca. 30 minute fixed-media composition for music and video. The musical component was created as a vehicle to showcase several approaches to electro-acoustic music composition –fft re-synthesis for time manipulation effects, the use of a custom-built software instrument which implements generative approaches to creating rhythm and pitch patterns, using a recording of rain to create rhythmic triggers for software instruments, and recording additional components with acoustic instruments. The video component transforms footage of natural landscapes filmed at several locations in North Carolina, Virginia, and West Virginia into a surreal narrative using a variety of color, lighting, distortion, and time-manipulation video effects.

(3) “‘The Invisible Mass:’ Exploring Compositional Technique in Alfred Schnittke’s Second Symphony” is an analytical article that focuses on Alfred Schnittke’s compositional technique as evidenced in the construction of his Second Symphony and discussed by the composer in a number of previously untranslated articles and interviews. Though this symphony is pivotal in the composer’s oeuvre, there are currently no scholarly articles that offer in-depth analyses of the piece. The article combines analyses of the harmony, form, and orchestration in the Second Symphony with relevant quotations from the composer, some from published and translated sources and others newly translated by the author from research at the Russian State Library in St. Petersburg. These offer a perspective on how Schnittke’s compositional technique combines systematic geometric design with keen musical intuition.

Communities of practice (CoPs) are among the professional development strategies most widely used in such fields as management and education. Though the approach has elicited keen interest, knowledge pertaining to its conceptual underpinnings is still limited, thus hindering proper assessment of CoPs' effects and the processes generating the latter. To address this shortcoming, this paper presents a conceptual model that was developed to evaluate an initiative based on a CoP strategy: Health Promotion Laboratories are a professional development intervention that was implemented in local public health organizations in Montreal (Quebec, Canada). The model is based on latest theories on work-group effectiveness and organizational learning and can be usefully adopted by evaluators who are increasingly called upon to illuminate decision-making about CoPs. Ultimately, validation of this conceptual model will help advance knowledge and practice pertaining to CoPs as well as professional and organizational development strategies in public health.
