Intangible resources have raised the interests of scholars from different research areas due to their importance as crucial factors for firm performance; yet, contributions to this field still lack a theoretical framework. This research analyses the state-of-the-art results reached in the literature concerning intangibles, their main features and evaluation problems and models. In search for a possible theoretical framework, the research draws a kind of indirect analysis of intangibles through the theories of the firm, their critic and developments. The heterodox approaches of the evolutionary theory and resource-based view are indicated as possible frameworks. Based on this theoretical analysis, organization capital (OC) is identified, for its features, as the most important intangible for firm performance. Empirical studies on the relationship intangibles-firm performance have been sporadic and have failed to reach firm conclusions with respect to OC; in the attempt to fill this gap, the effect of OC is tested on a large sample of European firms using the Compustat Global database. OC is proxied by capitalizing an income statement item (Selling, General and Administrative expenses) that includes expenses linked to information technology, business process design, reputation enhancement and employee training. This measure of OC is employed in a cross-sectional estimation of a firm level production function - modeled with different functional specifications (Cobb-Douglas and Translog) - that measures OC contribution to firm output and profitability. Results are robust and confirm the importance of OC for firm performance.

The characteristics of aphasics’ speech in various languages have been the core of numerous studies, but Arabic in general, and Palestinian Arabic in particular, is still a virgin field in this respect. However, it is of vital importance to have a clear picture of the specific aspects of Palestinian Arabic that might be affected in the speech of aphasics in order to establish screening, diagnosis and therapy programs based on a clinical linguistic database. Hence the central questions of this study are what are the main neurolinguistic features of the Palestinian aphasics’ speech at the phonetic-acoustic level and to what extent are the results similar or not to those obtained from other languages. In general, this study is a survey of the most prominent features of Palestinian Broca’s aphasics’ speech. The main acoustic parameters of vowels and consonants are analysed such as vowel duration, formant frequency, Voice Onset Time (VOT), intensity and frication duration. The deviant patterns among the Broca’s aphasics are displayed and compared with those of normal speakers. The nature of deficit, whether phonetic or phonological, is also discussed. Moreover, the coarticulatory characteristics and some prosodic patterns of Broca’s aphasics are addressed. Samples were collected from six Broca’s aphasics from the same local region. The acoustic analysis conducted on a range of consonant and vowel parameters displayed differences between the speech patterns of Broca’s aphasics and normal speakers. For example, impairments in voicing contrast between the voiced and voiceless stops were found in Broca’s aphasics. This feature does not exist for the fricatives produced by the Palestinian Broca’s aphasics and hence deviates from data obtained for aphasics’ speech from other languages. The Palestinian Broca’s aphasics displayed particular problems with the emphatic sounds. They exhibited deviant coarticulation patterns, another feature that is inconsistent with data obtained from studies from other languages. However, several other findings are in accordance with those reported from various other languages such as impairments in the VOT. The results are in accordance with the suggestions that speech production deficits in Broca’s aphasics are not related to phoneme selection but rather to articulatory implementation and some speech output impairments are related to timing and planning deficits.

This article offers an analysis of a struggle for control of a women’s development project in Nepal. The story of this struggle is worth telling, for it is rife with the gender politics and neo-colonial context that underscore much of what goes on in contemporary Nepal. In particular, my analysis helps to unravel some of the powerful discourses, threads of interest, and yet unintended effects inevitable under a regime of development aid. The analysis demonstrates that the employment of already available discursive figures of the imperialist feminist and the patriarchal third world man are central to the rhetorical strategies taken in the conflict. I argue that the trans-discursive or “borderland” nature of development in general and women’s development in particular result in different constructions of “development” goals, means and actors based not only on divergent cultural categories but on historically specific cultural politics. I argue further that the apolitical discourse of development serves to cloak its inherently political project of social and economic transformation, making conflicts such as the one that occurred in this case not only likely to occur but also likely to be misunderstood.

Purpose: Acupuncture is one of the complementary medicine therapies with the greatest demand in Switzerland and many other countries in the West and in Asia. Over the past decades, the pool of scientific literature in acupuncture has markedly increased. The diagnostic methods upon which acupuncture treatment is based, have only been addressed sporadically in scientific journals. The goal of this study is to assess the use of different diagnostic methods in the acupuncture practices and to investigate similarities and differences in using these diagnostic methods between physician and non-physician acupuncturists. Methods: 44 physician acupuncturists with certificates of competence in acupuncture – traditional chinese medicine (TCM) from ASA (Assoziation Schweizer Ärztegesellschaften für Akupunktur und Chinesische Medizin: the Association of Swiss Medical Societies for Acupuncture and Chinese Medicine) and 33 non-physician acupuncturists listed in the EMR (Erfahrungsmedizinisches Register: a national register, which assigns a quality label for CAM therapists in complementary and alternative medicine) in the cantons Basel-Stadt and Basel-Land were asked to fill out a questionnaire on diagnostic methods. The responder rate was 46.8% (69.7% non-physician acupuncturists and 29, 5% physician acupuncturists). Results: The results show that both physician and non-physician acupuncturists take patients’ medical history (94%), use pulse diagnosis (89%), tongue diagnosis (83%) and palpation of body and ear acupuncture points (81%) as diagnostic methods to guide their acupuncture treatments. Between the two groups, there were significant differences in the diagnostic tools being used. Physician acupuncturists do examine their patients significantly more often with western medical methods (p<.05) than this is the case for nonphysician acupuncturists. Non-physician acupuncturists use pulse diagnosis more often than physicians (p<.05). A highly significant difference was observed in the length of time spent with collecting patients’ medical history, where nonphysician acupuncturists clearly spent more time (p<.001). Conclusion: Depending on the educational background of the acupuncturist, different diagnostic methods are used for making the diagnosis. Especially the more time consuming methods like a comprehensive anamnesis and pulse diagnosis are more frequently employed by non-physician practitioners. Further studies will clarify if these results are valid for Switzerland in general, and to what extent the differing use of diagnostic methods has an impact on the diagnosis itself and on the resulting treatment methods, as well as on the treatment success and the patients’ satisfaction.

This honors thesis project uses history and literature to analyze the role of the myth of chivalry in mystifying racial violence and oppression in the American South. The central claim is that the myth of chivalry¿ and particularly the exaltation of the white woman¿ is a myth system used to justify racial violence, oppress white womanhood, and allow white patriarchy to maintain political, social and economic dominance. This project traces the role of literature, especially Sir Walter Scott¿s historical romance, in developing the foundational myths of a southern society based in violence, racial hierarchy and gender inequality. It then follows the role of white womanhood in this myth¿ the restrictions on miscegenation, the exaltation of pure white femininity, and the violent actions performed in the name of southern women. With this historical baseline established, this study then explores three works of historical fiction that attempt to subvert this mythology by critiquing and demystifying the myth of chivalry, while also offering counter-narratives to popularized history. These works are Charles Chesnutt¿s 1901 novel The Marrow of Tradition¬, which analyzes the 1898 Wilmington N.C. race riot, Gwendolyn Brooks¿ 1960 poem ¿A Bronzeville Mother Loiters in Mississippi. Meanwhile, a Mississippi Mother Burns Bacon¿ and Lewis Nordan¿s 1993 novel Wolf Whistle, two works about Emmett Till¿s tragic murder in 1955. This study, then, illuminates the intersection of literature and mythology, revealing how literature is useful for both creating and subverting myth¿and revealing how authors undertake this task.

Insulin-like growth factor I (IGF-I) plays a key role in the complex system that regulates bony fish growth, differentiation, and reproduction. The major source of circulating IGF-I is liver, but IGF-I-producing cells also occur in other organs, including the gonads. Because no data are available on the potential production sites of IGF-I in gonad development, developmental stages of monosex breedings of male and female tilapia from 0 day postfertilization (DPF) to 90 DPF were investigated for the production sites of IGF-I at the peptide (immunohistochemistry) and mRNA (in situ hybridization) level. IGF-I mRNA first appeared in somatic cells of the male and female gonad anlage at 7 DPF followed by IGF-I peptide around 9-10 DPF. Gonad anlagen were detected from 7 DPF. Starting at 7 DPF, IGF-I peptide but no IGF-I mRNA was observed in male and female primordial germ cells (PGCs) provided that IGF-I mRNA was not under the detection level, this observation may suggest that IGF-I originates from the somatic cells and is transferred to the PGCs or is of maternal origin. While in female germ cells IGF-I mRNA and peptide appeared at 29 DPF, in male germ cells both were detected as late as at 51-53 DPF. It is assumed that the production of IGF-I in the germ cells is linked to the onset of meiosis that in tilapia ovary starts at around 28 DPF and in testes at around 52-53 DPF. In adult testis, IGF-I mRNA and peptide occurred in the majority of spermatogonia and spermatocytes as well as in Leydig cells, the latter indicating a role of IGF-I in the synthesis of male sex steroids. In adult ovary, IGF-I mRNA and IGF-I peptide were always present in small and previtellogenic oocytes but only IGF-I peptide infrequently occurred in oocytes at the later stages. IGF-I expression appeared in numerous granulosa and some theca cells of follicles at the lipid stage and persisted in follicles with mature oocytes. The results suggest a crucial role of local IGF-I in the formation, differentiation and function of tilapia gonads.

Many natural and synthetic compounds present in the environment exert a number of adverse effects on the exposed organisms, leading to endocrine disruption, for which they were termed endocrine disrupting chemicals (EDCs). A decrease in reproduction success is one of the most well-documented signs of endocrine disruption in fish. Estrogens are steroid hormones involved in the control of important reproduction-related processes, including sexual differentiation, maturation and a variety of others. Careful spatial and temporal balance of estrogens in the body is crucial for proper functioning. At the final step of estrogen biosynthesis, cytochrome P450 aromatase, encoded by the cyp19 gene, converts androgens into estrogens. Modulation of aromatase CYP19 expression and function can dramatically alter the rate of estrogen production, disturbing the local and systemic levels of estrogens. In the present review, the current progress in CYP19 characterization in teleost fish is summarized and the potential of several classes of EDCs to interfere with CYP19 expression and activity is discussed. Two cyp19 genes are present in most teleosts, cyp19a and cyp19b, primarily expressed in the ovary and brain, respectively. Both aromatase CYP19 isoforms are involved in the sexual differentiation and regulation of the reproductive cycle and male reproductive behavior in diverse teleost species. Alteration of aromatase CYP19 expression and/or activity, be it upregulation or downregulation, may lead to diverse disturbances of the above mentioned processes. Prediction of multiple transcriptional regulatory elements in the promoters of teleost cyp19 genes suggests the possibility for several EDC classes to affect cyp19 expression on the transcriptional level. These sites include cAMP responsive elements, a steroidogenic factor 1/adrenal 4 binding protein site, an estrogen-responsive element (ERE), half-EREs, dioxin-responsive elements, and elements related to diverse other nuclear receptors (peroxisome proliferator activated receptor, retinoid X receptor, retinoic acid receptor). Certain compounds including phytoestrogens, xenoestrogens, fungicides and organotins may modulate aromatase CYP19 activity on the post-transcriptional level. As is shown in this review, diverse EDCs may affect the expression and/or activity of aromatase cyp19 genes through a variety of mechanisms, many of which need further characterization in order to improve the prediction of risks posed by a contaminated environment to teleost fish population.

Cet article traite des expressions de la perception sensuelle de l’ouest nilotique. La première partie de l’article présente une terminologie ophrésiologique en louo et burun et démontre que cette catégorie lexicale détient aussi une catégorie grammaticale particulière. Phénomènes très rares dans les langues du monde, les termes ophrésiologiques sont seulement présentés sous forme introductive pour encourager davantage les recherches futures. La seconde partie de l’article porte sur les descriptions des couleurs utilisées pour les animaux domestiques. Quand les modalités de l’économie changent, les noms utilisés pour les couleurs des animaux peuvent aussi être employés pour d’autres concepts culturels. La troisième partie de l’article montre que les classificateurs nominaux en mabaan (burun) expriment des principes concernant le toucher en tant que structure cognitive. En conséquence, différents procédés de grammaticalisation sont assumés et corrélés avec des ponctuations dans l’histoire culturelle et mentale des ancêtres des locuteurs de l’ouest nilotique.

L’internet est reconnue de manière générale comme un instrument de recherche valable. Bien que les langues africaines ne soient pas bien représentées sur internet il y a assez d’informations qui peuvent être découvertes dans la recherche sur terrain virtuel. Des petits vocabulaires et des descriptions de plusieurs langues africaines sont écrits par des auteurs individuels, des départements d’universités et des agences de voyages. Des textes en langues africaines sont en majorité publiés par des missionaries ou des ONGs. Ces données tendent à refléter les variantes standards des langues utilisées. Ce sont des contributions dans des forums qui sont témoins d’un langage proche de la langue parlée. On recherche les données linguistiques en utilisant les noms des langues respectives combinés avec des termes tels que “langue”, “grammaire”, “cours” ou le nom d’un auteur comme terme de recherche. Des chaînes de mots (en guillemets) qui sont très courantes dans le langage parlé et/ou écrit peuvent constituer de bons termes de recherche pour trouver des textes ou des contributions dans des forums.

Intensified aquaculture has strong impact on fish health by stress and infectious diseases and has stimulated the interest in the orchestration of cytokines and growth factors, particularly their influence by environmental factors, however, only scarce data are available on the GH/IGF-system, central physiological system for development and tissue shaping. Most recently, the capability of the host to cope with tissue damage has been postulated as critical for survival. Thus, the present study assessed the combined impacts of estrogens and bacterial infection on the insulin-like growth factors (IGF) and tumor-necrosis factor (TNF)-α. Juvenile rainbow trout were exposed to 2 different concentrations of 17β-estradiol (E2) and infected with Yersinia ruckeri. Gene expressions of IGF-I, IGF-II and TNF-α were measured in liver, head kidney and spleen and all 4 estrogen receptors (ERα1, ERα2, ERβ1 and ERβ2) known in rainbow trout were measured in liver. After 5 weeks of E2 treatment, hepatic up-regulation of ERα1 and ERα2, but down-regulation of ERß1 and ERß2 were observed in those groups receiving E2-enriched food. In liver, the results further indicate a suppressive effect of Yersinia-infection regardless of E2-treatment on day 3, but not of E2-treatment on IGF-I whilst TNF-α gene expression was not influenced by Yersinia-infection but was reduced after 5 weeks of E2-treatment. In spleen, the results show a stimulatory effect of Yersinia-infection, but not of E2-treatment on both, IGF-I and TNF-α gene expressions. In head kidney, E2 strongly suppressed both, IGF-I and TNF-α. To summarise, the treatment effects were tissue- and treatment-specific and point to a relevant role of IGF-I in infection.

INTRODUCTION As the importance of systematic review (SR) conclusions relies upon the scientific rigor of methods and the currency of evidence, we aimed to investigate the currency of orthodontic SRs using as proxy the time from the initial search to publication. Additionally, SR information regarding reporting guidelines, registration, and literature searches were recorded when available. MATERIALS AND METHODS A systematic PubMed search was carried out using the Clinical Queries page to identify orthodontic SRs cited between 1 January 2008 and 7 November 2013. Data related to reporting guidelines, review registration, dates of review processing, literature search, and abstract reporting were retrieved and classified by journal type. Survival analysis was used to assess the time to reach predefined manuscript stages for orthodontic and non-orthodontic journals. RESULTS One hundred twenty seven of the originally identified 585 SRs were considered eligible. The median interval from search until publication was 13.2 months (interquartile range: IQR = 9.7 months) irrespective of the journal type. There was evidence (P = 0.05) that SRs published by non-orthodontic journals appeared in PubMed faster than in orthodontic journals (non-orthodontic: median = 6.5 months; IQR = 5.7 months; orthodontic: median = 10.2 months; IQR = 5.6 months) from submission to publication and from acceptance to publication (non-orthodontic: median = 1.5 months; IQR = 2.4 months; orthodontic: median = 6.0 months; IQR = 6.2 months; P < 0.001). More than half of these SRs did not cite adherence to any reporting guidelines, whereas all but five studies were not prospectively registered. Search of unpublished research was undertaken in approximately 21 per cent and 29 per cent of the SRs published in non-orthodontic and orthodontic periodicals, respectively. CONCLUSIONS This study indicates that SR users should be aware that median time for orthodontic SRs from search to publication is 13.2 months. SRs published in non-orthodontic journals are likely to be more current in terms of submission until time to publication and acceptance until time to publication compared with those published in orthodontic journals.

Synopsis: Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. Our study seeks to reveal and analyse the causes for professionalization processes in international sport federations, the forms resulting from it, as well as related consequences. Abstract: AIM OF ABSTRACT/PAPER - RESEARCH QUESTION Sport organisations are facing multiple challenges originating from an increasingly complex and dynamic environment in general, and from internal changes in particular. In this context, professionalization seems to have been adopted by sport organisations as an appropriate strategy to respond to pressures such as becoming more “business-like”. The ongoing study seeks to reveal and analyse the internal and external causes for professionalization processes in international sport federations, the forms resulting from it (e.g. organisational, managerial, economic) as well as related consequences on objectives, values, governance methods, performance management or again rationalisation. THEORETICAL BACKGROUND/LITERATURE REVIEW Studies on sport as specific non-profit sector mainly focus on the prospect of the “professionalization of individuals” (Thibault, Slack & Hinings, 1991), often within sport clubs (Thiel, Meier & Cachay, 2006) and national sport federations (Seippel, 2002) or on organisational change (Griginov & Sandanski, 2008; Slack & Hinings, 1987, 1992; Slack, 1985, 2001), thus leaving broader analysis on governance, management and professionalization in sport organisations an unaccomplished task. In order to further current research on above-mentioned topics, our intention is to analyse causes, forms and consequences of professionalisation processes in international sport federations. The social theory of action (Coleman, 1986; Esser, 1993) has been defined as appropriate theoretical framework, deriving in the following a multi-level framework for the analysis of sport organisations (Nagel, 2007). In light of the multi-level framework, sport federations are conceptualised as corporative actors whose objectives are defined and implemented with regard to the interests of member organisations (Heinemann, 2004) and/or other pressure groups. In order to understand social acting and social structures (Giddens 1984) of sport federations, two levels are in the focus of our analysis: the macro level examining the environment at large (political, social, economic systems etc.) and the meso level (Esser, 1999) examining organisational structures, actions and decisions of the federation’s headquarter as well as member organisations. METHODOLOGY, RESEARCH DESIGN AND DATA ANALYSIS The multi-level framework mentioned seeks to gather and analyse information on causes, forms and consequences of professionalization processes in sport federations. It is applied in a twofold approach: first an exploratory study based on nine semi-structured interviews with experts from umbrella sport organisations (IOC, WADA, ASOIF, AIOWF, etc.) as well as the analysis of related documents, relevant reports (IOC report 2000 on governance reform, Agenda 2020, etc.) and important moments of change in the Olympic Movement (Olympic revenue share, IOC evaluation criteria, etc.); and secondly several case studies. Whereas the exploratory study seeks more the causes for professionalization on an external, internal and headquarter level as depicted in the literature, the case studies rather focus on forms and consequences. Applying our conceptual framework, the analysis of forms is built around three dimensions: 1) Individuals (persons and positions), 2) Processes, structures (formalisation, specialisation), 3) Activities (strategic planning). With regard to consequences, we centre our attention on expectations of and relationships with stakeholders (e.g. cooperation with business partners), structure, culture and processes (e.g. governance models, performance), and expectations of and relationships with member organisations (e.g. centralisation vs. regionalisation). For the case studies, a mixed-method approach is applied to collect relevant data: questionnaires for rather quantitative data, interviews for rather qualitative data, as well as document and observatory analysis. RESULTS, DISCUSSION AND IMPLICATIONS/CONCLUSIONS With regard to causes of professionalization processes, we analyse the content of three different levels: 1. the external level, where the main pressure derives from financial resources (stakeholders, benefactors) and important turning points (scandals, media pressure, IOC requirements for Olympic sports); 2. the internal level, where pressure from member organisations turned out to be less decisive than assumed (little involvement of member organisations in decision-making); 3. the headquarter level, where specific economic models (World Cups, other international circuits, World Championships), and organisational structures (decision-making procedures, values, leadership) trigger or hinder a federation’s professionalization process. Based on our first analysis, an outline for an economic model is suggested, distinguishing four categories of IFs: “money-generating IFs” being rather based on commercialisation and strategic alliances; “classical Olympic IFs” being rather reactive and dependent on Olympic revenue; “classical non-Olympic IFs” being rather independent of the Olympic Movement; and “money-receiving IFs” being dependent on benefactors and having strong traditions and values. The results regarding forms and consequences will be outlined in the presentation. The first results from the two pilot studies will allow us to refine our conceptual framework for subsequent case studies, thus extending our data collection and developing fundamental conclusions.

This thesis is an examination of the memoirs of three core Holocaust writers, Elie Wiesel (Night and Day), Primo Levi (If This is A Man), and Charlotte Delbo (Auschwitz and After), exploring the ways in which each of the three authors uses his or her memoir to simultaneously document and resist the dehumanizing influence of the concentration camp experience.
