Intercultural training for international placements

Despite its increasing popularity, much intercultural training is not developed with the same level of rigour as training in other areas. Further, research on intercultural training has brought inconsistent results about the effectiveness of such training. This PhD thesis develops a rigorous model of intercultural training and applies it to the preparation of British students going on work/study placements in France and Germany. It investigates the reasons for inconsistent training success by looking at the cognitive learning processes in intercultural training, relating them to training goals, and by examining the short- and long-term transfer of intercultural training into real-life encounters with people from other cultures. Two cognitive trainings based on critical incidents were designed for online delivery. The training content relied on cultural practice dimensions from the GWBE study (House, Hanges, Javidan, Dorfman & Gupta, 2004). Of the two trainings, the 'singlemode training' aimed to develop declarative knowledge, which is necessary to analyse and understand other cultures. The 'concurrent training' aimed to develop declarative and procedural knowledge, which is needed to develop skills for dealing with difficult situations in a culturally appropriate way. Participants (N-48) were randomly assigned to one of the two training conditions. Declarative learning appeared as a process of steady knowledge increase, while procedural learning involved cognitive re-categorisation rather than knowledge increase. In a negotiation role play with host-country nationals directly after the online training, participants of the concurrent training exhibited a more initiative negotiation style than participants of the single-mode training. Comparing cultural adjustment and performance of training participants during their time abroad with an untrained control group, participants of the concurrent training showed the qualitatively best development in adjustment and performance. Besides intercultural training, multicultural personality traits were assessed and proved to be a powerful predictor of adjustment and, indirectly, of performance abroad.

iServe:a serious game for servitization

Servitization concerns the process of manufacturers shifting from a focus on producing and selling tangible goods to service-based business models. Factors that drive adoption of servitization are financial, strategic (competitive advantage) and marketing. However, uptake is slow and active efforts are being made to transfer knowledge about servitization to the manufacturing sector. This paper presents early results from the first test of a serious computer game which has the goal of educating managers about what advanced services are and how they fit in supply chains. Results suggest the role-play scenario tested is appropriate for an audience of largely non-expert gamers, and that the approach has the potential to instruct users about the role of services in the supply chain.

Do strategic groups play a role in the SME financing process?

This exploratory paper, developing a conceptual model of owner-manager characteristics and access to finance, aims to investigate whether the concept of strategic groups plays a role in the process of small and medium-sized enterprises (SMEs) accessing finance. Strategic groups are groups of firms making similar patterns of investments in order to achieve their goals. This paper explores how strategic groups, which represent a classification of SMEs based upon their realised strategies, helps to provide an understanding of the success of SMEs in raising finance. The data, from a representative survey of 400 SMEs conducted by the Barclays Bank Telephone Research Unit, were subject to two-stage cluster analysis, thus codified into strategic groups using the natural rhythm of the data, rather than any subjective and value-laden categories being imposed by the authors. The findings show clear differentiation between strategic groups of SMEs, the characteristics of their owner-managers, and the financing strategies adopted. As such, the paper develops a novel typology of strategic groups of SMEs which, therefore, informs their financing strategies, as well as advising other stakeholders.

Angiotensin II directly induces muscle protein catabolism through the ubiquitin-proteasome proteolytic pathway and may play a role in cancer cachexia

The ability of angiotensin I (Ang I) and II (Ang II) to induce directly protein degradation in skeletal muscle has been studied in murine myotubes. Angiotensin I stimulated protein degradation with a parabolic dose-response curve and with a maximal effect between 0.05 and 0.1 μM. The effect was attenuated by coincubation with the angiotensin-converting enzyme (ACE) inhibitor imidaprilat, suggesting that angiotensin I stimulated protein degradation through conversion to Ang II. Angiotensin II also stimulated protein breakdown with a similar dose-response curve, and with a maximal effect between 1 and 2.5 μM. Total protein degradation, induced by both Ang I and Ang II, was attenuated by the proteasome inhibitors lactacystin (5 μM) and MG132 (10 μM), suggesting that the effect was mediated through upregulation of the ubiquitin-proteasome proteolytic pathway. Both Ang I and Ang II stimulated an increased proteasome 'chymotrypsin-like' enzyme activity as well as an increase in protein expression of 20S proteasome α-subunits, the 19S subunits MSSI and p42, at the same concentrations as those inducing protein degradation. The effect of Ang I was attenuated by imidaprilat, confirming that it arose from conversion to Ang II. These results suggest that Ang II stimulates protein degradation in myotubes through induction of the ubiquitin-proteasome pathway. Protein degradation induced by Ang II was inhibited by insulin-like growth factor and by the polyunsaturated fatty acid, eicosapentaenoic acid. These results suggest that Ang II has the potential to cause muscle atrophy through an increase in protein degradation. The highly lipophilic ACE inhibitor imidapril (Vitor™) (30 mg kg-1) attenuated the development of weight loss in mice bearing the MAC16 tumour, suggesting that Ang II may play a role in the development of cachexia in this model. © 2005 Cancer Research.

Epithelial transport and deamidation of gliadin peptides:a role for coeliac disease patient immunoglobulin A

In coeliac disease, the intake of dietary gluten induces small-bowel mucosal damage and the production of immunoglobulin (Ig)A class autoantibodies against transglutaminase 2 (TG2). We examined the effect of coeliac patient IgA on the apical-to-basal passage of gluten-derived gliadin peptides p31-43 and p57-68 in intestinal epithelial cells. We demonstrate that coeliac IgA enhances the passage of gliadin peptides, which could be abolished by inhibition of TG2 enzymatic activity. Moreover, we also found that both the apical and the basal cell culture media containing the immunogenic gliadin peptides were able to induce the proliferation of deamidation-dependent coeliac patient-derived T cells even in the absence of exogenous TG2. Our results suggest that coeliac patient IgA could play a role in the transepithelial passage of gliadin peptides, a process during which they might be deamidated.

(Para)translated ideologies in Simone de Beauvoir's 'Le deuxième sexe': the (para)translator's role

At the beginning of the 80s new approaches to translation were emerging in such a way that, in the global context of postmodernism and poststructuralism, they provoked a reassessment of Translation Studies (TS), acknowledging ideologies as a relevant concept to TS and considering the political and visible role of the translator. This introduction aims to establish a basic theoretical framework in which we can develop an analysis of the ‘alterations’ that, consciously or unconsciously, translators have imposed on Le deuxième sexe (1949, Gallimard) by Simone de Beauvoir for the last fifty years. Furthermore, it is essential to examine the divergences of the censoring attitude adopted by the first male translators (Parshley, Palant and Milliet) who considered this text to be a sex manual, and the one adopted by more recent female translators (Martorell and Simons) who considered it to be a philosophical book on feminism. Nevertheless, despite this tendency to consider that translators are the only professionals responsible for the translation process, it is necessary to bear in mind the work carried out by the paratranslator, who is the real censor and ‘decider’ of the way a work is presented to the translation community. Paratranslators work with paratexts (also known as ‘analysis-spaces’), and this makes it possible to study the ideological adaptation that a cultural object undergoes when it is incorporated into a new culture and society (covers, volumes, tables of contents, titles, iconic or visual elements and so forth). In short, the analysis of the texts and paratexts of Le deuxième sexe, along with its subsequent translations and rewritings into Spanish, Portuguese and English, will help reveal the function of the censoring apparatus and demonstrate the essential role that –without exception– ideologies play in the professional work of translation and paratranslation, since they have a decisive influence on the reception of the cultural (and ideological) object, in both the society in which it is created and that in which it is received.

Relating two simultaneous events in discourse: the role of on-goingness devices in L1 Tunisian Arabic, L1 French and L2 French by Tunisian learners

Our PhD study focuses on the role of aspectual marking in expressing simultaneity of events in Tunisian Arabic as a first language, French as a first language, as well as in French as a second language by Tunisian learners at different acquisitional stages. We examine how the explicit markers of on-goingness qa:’id and «en train de» in Tunisian Arabic and in French respectively are used to express this temporal relation, in competition with the simple forms, the prefixed verb form in Tunisian Arabic and the présent de l’indicatif in French. We use a complex verbal task of retelling simultaneous events sharing an interval on the time axis based on eight videos presenting two situations happening in parallel. Two types of simultaneity are exploited: perfect simultaneity (when the two situations are parallel to each other) and inclusion (one situation is framed by the second one). Our informants in French and in Tunisian Arabic have two profiles, highly educated and low educated speakers. We show that the participants’ response to the retelling task varies according to their profiles, and so does their use of the on-goingness devices in the expression of simultaneity. The differences observed between the two profile groups are explained by the degree to which the speakers have developed a habit of responding to tasks. This is a skill typically acquired during schooling. We notice overall that the use of qa:’id as well as of «en train de» is less frequent in the data than the use of the simple forms. However, qa:’id as well as «en train de» are employed to play discursive roles that go beyond the proposition level. We postulate that despite the shared features between Tunisian Arabic and French regarding marking the concept of on-goingness, namely the presence of explicit lexical, not fully grammaticalised markers competing with other non-marked forms, the way they are used in the discourse of simultaneous events shows clear differences. We explain that «en train de» plays a more contrastive role than qa:’id and its use in discourse obeys a stricter rule. In cases of the inclusion type of simultaneity, it is used to construe the ‘framing’ event that encloses the second event. In construing perfectly simultaneneous events, and when both «en train de» and présent de l’indicatif are used, the proposition with «en train de» generally precedes the proposition with présent de l’indicatif, and not the other way around. qa:id obeys, but to a less strict rule as it can be used interchangeably with the simple form regardless of the order of propositions. The contrastive analysis of French L1 and L2 reveals learners’ deviations from natives’ use of on-goingness devices. They generalise the use of «en train de» and apply different rules to the interaction of the different marked and unmarked forms in discourse. Learners do not master its role in discourse even at advanced stages of acquisition despite its possible emergence around the basic and intermediate varieties. We conclude that the native speakers’ use of «en train de» involves mastering its role at the macro-structure level. This feature, not explicitly available to learners in the input, might persistently present a challenge to L2 acquisition of the periphrasis.

The role of texture amplitude in shape from shading: evidence from a haptic matching task

The pattern of illumination on an undulating surface can be used to infer its 3-D form (shape from shading). But the recovery of shape would be invalid if the shading actually arose from reflectance variation. When a corrugated surface is painted with an albedo texture, the variation in local mean luminance (LM) due to shading is accompanied by a similar modulation in texture amplitude (AM). This is not so for reflectance variation, nor for roughly textured surfaces. We used a haptic matching technique to show that modulations of texture amplitude play a role in the interpretation of shape from shading. Observers were shown plaid stimuli comprising LM and AM combined in-phase (LM+AM) on one oblique and in anti-phase (LM-AM) on the other. Stimuli were presented via a modified ReachIN workstation allowing the co-registration of visual and haptic stimuli. In the first experiment, observers were asked to adjust the phase of a haptic surface, which had the same orientation as the LM+AM combination, until its peak in depth aligned with the visually perceived peak. The resulting alignments were consistent with the use of a lighting-from-above prior. In the second experiment, observers were asked to adjust the amplitude of the haptic surface to match that of the visually perceived surface. Observers chose relatively large amplitude settings when the haptic surface was oriented and phase-aligned with the LM+AM cue. When the haptic surface was aligned with the LM-AM cue, amplitude settings were close to zero. Thus the LM/AM phase relation is a significant visual depth cue, and is used to discriminate between shading and reflectance variations.

Origins of molecular neurobiology:The role of the physicists

The revolution in the foundations of physics at the beginning of the twentieth century suggested to several of its most prominent workers that biology was ripe for something similar. In consequence, a number of physicists moved into biology. They were highly influential in initiating a molecular biology in the 1950s. Two decades later it seemed to several of these migrants, and those they had influenced, that the major problems in molecular biology had been solved, and that it was time to move on to what seemed to them the final problem: the nervous system, consciousness, and the age-old mind-body problem. This paper reviews this "double migration" and shows how the hopes of the first generation of physicist-biologists were both realized and dashed. No new physical principles were discovered at work in the foundations of biology or neuroscience. On the other hand, the mind-set of those trained in physics proved immensely valuable in analyzing fundamental issues in both biology and neuroscience. It has been argued that the outcome of the molecular biology of the 1950s was a change in the concept of the gene from that of "a mysterious entity into that of a real molecular object" (Watson, 1965, p.6); the gates and channels which play such crucial roles in the functioning of nervous systems have been transformed in a similar way. Studies on highly simplified systems have also opened the prospect of finding the neural correlatives of numerous behaviors and neuropathologies. This increasing understanding at the molecular level is invaluable not only in devising rational therapies but also, by defining the material substrate of consciousness, in bringing the mind-body problem into sharper focus.

Attentional shifting and the role of the dorsal pathway in visual word recognition

A substantial amount of evidence has been collected to propose an exclusive role for the dorsal visual pathway in the control of guided visual search mechanisms, specifically in the preattentive direction of spatial selection [Vidyasagar, T. R. (1999). A neuronal model of attentional spotlight: Parietal guiding the temporal. Brain Research and Reviews, 30, 66-76; Vidyasagar, T. R. (2001). From attentional gating in macaque primary visual cortex to dyslexia in humans. Progress in Brain Research, 134, 297-312]. Moreover, it has been suggested recently that the dorsal visual pathway is specifically involved in the spatial selection and sequencing required for orthographic processing in visual word recognition. In this experiment we manipulate the demands for spatial processing in a word recognition, lexical decision task by presenting target words in a normal spatial configuration, or where the constituent letters of each word are spatially shifted relative to each other. Accurate word recognition in the Shifted-words condition should demand higher spatial encoding requirements, thereby making greater demands on the dorsal visual stream. Magnetoencephalographic (MEG) neuroimaging revealed a high frequency (35-40 Hz) right posterior parietal activation consistent with dorsal stream involvement occurring between 100 and 300 ms post-stimulus onset, and then again at 200-400 ms. Moreover, this signal was stronger in the shifted word condition, compared to the normal word condition. This result provides neurophysiological evidence that the dorsal visual stream may play an important role in visual word recognition and reading. These results further provide a plausible link between early stage theories of reading, and the magnocellular-deficit theory of dyslexia, which characterises many types of reading difficulty. © 2006 Elsevier Ltd.

Leadership development: the role of developmental readiness, personality dispositions, and individual values

Increased awareness of the crucial role of leadership as a competitive advantage for organisations (McCall, 1998; Petrick, Scherer, Brodzinski, Quinn, & Ainina, 1999) has led to billions spent on leadership development programmes and training (Avolio & Hannah, 2008). However, research reports confusing and contradictory evidence regarding return on investment and developmental outcomes, and a lot of variance has been observed across studies (Avolio, Reichard, Hannah, Walumbwa, & Chan, 2009). The purpose of this thesis is to understand the mechanisms underlying this variability in leadership development. Of the many factors at play in the process, such as programme design and delivery, organisational support, and perceptions of relevance (Mabey, 2002; Day, Harrison, & Halpin, 2009), individual differences and characteristics stand out. One way in which individuals differ is in their Developmental Readiness (DR), a concept recently introduced in the literature that may well explain this variance and which has been proposed to accelerate development (Avolio & Hannah, 2008, 2009). Building on previous work, DR is introduced and conceptualised somewhat differently. In this study, DR is construed of self-awareness, self-regulation, and self-motivation, proposed by Day (2000) to be the backbones of leadership development. DR is suggested to moderate the developmental process. Furthermore, personality dispositions and individual values are proposed to be precursors of DR. The empirical research conducted uses a pre-test post-test quasi-experimental design. Before conducting the study, though, both a measure of Developmental Readiness and a competency profiling measure are tested in two pilot studies. Results do not find evidence of a direct effect of leadership development programmes on development, but do support an interactive effect between DR and leadership development programmes. Personality dispositions Agreeableness, Conscientiousness, and Openness to Experience and value orientations Conservation, Open, and Closed Orientation are found to significantly predict DR. Finally, the theoretical and practical implications of findings are discussed.

Third sector organisations and social welfare : a study of the role of social service and charitable organisations in Taiwan

This study is about the role and operation of ‘third sector’ organisations (TSOs) within the Taiwanese social welfare context. TSOs have increased dramatically and become actively involved in social service provision. This phenomenon has not only had significant impact on the development and operation of TSOs in Taiwan but it is also of increasing interest to public policy academics. The latter are especially interested in the implications for the government-third sector relationship. This research examines the reasons why TSOs have been established, why they actively participate in social service provision, and their role and operation within the social welfare context of Taiwan. The study has both quantitative and qualitative data. It sampled ‘social service’ and ‘charitable’ organisations (SSCOs), which are the main type of TSOs in Taiwan, to examine their role, operation and interaction with government. Questionnaires were mailed to collect quantitative data first. After the quantitative data were collected and analysed, semi-structured interviews were undertaken to collect qualitative data. The study found that TSOs in Taiwan exist in a highly institutionalised environment, which is affected by traditional Confucian ideas and contemporary Western ideas such as social justice and civil rights. The rapid growth of TSOs has a strong connection with the desire to fill social service gaps left by government and family. TSOs mainly play the role of service provider rather than that of advocate. They cooperate with government in social service provision and have developed different types of symbiotic relationships with government. A ‘resonance effect’ between government and TSOs was also found as they implement social policy.

The role of cytoskeletal proteins in the mechanism of insulin release

This thesis is concerned with the role of /3-cell cytoskeletal proteins in the mechanism of insulin release from islets of experimental animals, the Aston obese diabetic hyperglycaemic (ob/ob) mouse and their lean littermates and the cultural insulin secreting /?-cell lines, HIT-TT5 and RINm5F. Investigations were carried out into the glucose induced insulin response of the lean and obese mouse islets and HIT-TI5 cells and the D-glyceraldehyde response of RINm5F cells using a static incubation system. Colchicine was found to inhibit insulin release from both lean and obese mouse islets more significantly than cultured TTT-TI5 and RINm5F cells. (Colchicine pre-treatment also inhibited the second phase of insulin release from perifused lean mouse islets and HIT-TI5 cells). Cytocha-lasin B, used to investigate the role of the microfilamentous system in the mechanism of insulin release enhanced insulin release from both lean and obese mouse islets to a significantly greater degree than that from cultured HIT-TI5 and RINm5F cells. Pre-treatment of isolated lean and obese mouse islets and cultured /?-cells with a combination of colchicine and cytochalasin B significantly reduced the insulin response of the HIT-TI5 and RINm5F cells compared with the control values suggesting that intact microtubules are more important for the sustained release of insulin than the microfilamentous system. However, the response was not so clearly defined with the lean and obese mouse islets. Tubulin was separated from the extracts of lean mouse islets and the HIT-TI5 and RINm5F cells and actin was separated from all of the cell types including the obese mouse islets by SDS- polyacrylamide electrophoresis. A tubulin radioimmunoassay and a colchicine binding assay were developed to measure the tubulin content of lean and obese mouse islets, and the shift between the proportions of tubulin dimers and polymerized tubulin under stimulatory and non-stimulatory conditions. The assay methods developed were not prone to be accurate, sensitive and precise but gave some indication of the shift from unpolymerised to polymerised tubulin during glucose stimulated insulin release. These studies show that microtubules do play a fundamental role in the mechanism of insulin release from both islets and cultured HIT-TI5 and RINm5F cells.

The role of line managers in employee career management:an attachment theory perspective

Line managers increasingly play a key role in organizational career development systems, yet few studies have examined the nature of this role or its implications for employee career attitudes and behaviors. In two studies, we used attachment theory to explore this issue. In Study 1, in-depth interviews (N = 20) showed that employees viewed career management as a relational process in which line managers are expected to act as ‘caregiver’ to support individualized career development. Study 2 was a large-scale international survey (N = 891). Participants scoring higher on attachment avoidance in their line manager relationships reported more negative perceptions of career growth opportunities, lower participation in organizational career development activities and higher turnover intentions. Trust in the organization partially mediated the relationship. Theoretical and practical implications for HRM are discussed.
