Does culture affect public service motivation? Evidence of sub-national differences in Switzerland

This article explores societal culture as an antecedent of public service motivation. Culture can be a major factor in developing an institution-based theory of public service motivation. In the field of organization theory, culture is considered a fundamental factor for explaining organization behavior. But our review of the literature reveals that culture has not been fully integrated into public service motivation theory or carefully investigated in this research stream. This study starts to fill this gap in the literature by using institutionalism and social-identity theory to predict how the sub-national Germanic and Latin cultures of Switzerland, which are measured through the mother tongues of public employees and the regional locations of public offices, affect their levels of public service motivation. Our analysis centers on two large data sets of federal and municipal employees, and produces evidence that culture has a consistent impact on public service motivation. The results show that Swiss German public employees have a significantly higher level of public service motivation on the whole, while Swiss French public employees have a significantly lower level overall. Implications for theory development and future research are discussed.

Insights into the regulation of GPEET procyclin during differentiation from early to late procyclic forms of Trypanosoma brucei.

The procyclic form of Trypanosoma brucei colonises the gut of its insect vector, the tsetse fly. GPEET and EP procyclins constitute the parasite's surface coat at this stage of the life cycle, and the presence or absence of GPEET distinguishes between early and late procyclic forms, respectively. Differentiation from early to late procyclic forms in vivo occurs in the fly midgut and can be mimicked in culture. Our analysis of this transition in vitro delivered new insights into the process of GPEET repression. First, we could show that parasites followed a concrete sequence of events upon triggering differentiation: after undergoing an initial growth arrest, cells lost GPEET protein, and finally late procyclic forms resumed proliferation. Second, we determined the stability of both GPEET and EP mRNA during differentiation. GPEET mRNA is exceptionally stable in early procyclic forms, with a half-life >6h. The GPEET mRNA detected in late procyclic form cultures is a mixture of transcripts from both bona fide late procyclic forms and GPEET-positive 'laggard' parasites present in these cultures. However, its stability was clearly reduced during differentiation and in late procyclic form cultures. Alternatively processed GPEET transcripts were enriched in samples from late procyclic forms, suggesting that altered mRNA processing might contribute to repression of GPEET in this developmental stage. In addition, we detected GPEET transcripts with non-templated oligo(U) tails that were enriched in late procyclic forms. To the best of our knowledge, this is the first study reporting a uridylyl-tailed, nuclear-encoded mRNA species in trypanosomatids or any other protozoa.

Major challenges in clinical management of TB/HIV co-infected patients in Eastern Europe compared with Western Europe and Latin America.

INTRODUCTION Rates of both TB/HIV co-infection and multi-drug-resistant (MDR) TB are increasing in Eastern Europe (EE). Data on the clinical management of TB/HIV co-infected patients are scarce. Our aim was to study the clinical characteristics of TB/HIV patients in Europe and Latin America (LA) at TB diagnosis, identify factors associated with MDR-TB and assess the activity of initial TB treatment regimens given the results of drug-susceptibility tests (DST). MATERIAL AND METHODS We enrolled 1413 TB/HIV patients from 62 clinics in 19 countries in EE, Western Europe (WE), Southern Europe (SE) and LA from January 2011 to December 2013. Among patients who completed DST within the first month of TB therapy, we linked initial TB treatment regimens to the DST results and calculated the distribution of patients receiving 0, 1, 2, 3 and ≥4 active drugs in each region. Risk factors for MDR-TB were identified in logistic regression models. RESULTS Significant differences were observed between EE (n=844), WE (n=152), SE (n=164) and LA (n=253) for use of combination antiretroviral therapy (cART) at TB diagnosis (17%, 40%, 44% and 35%, p<0.0001), a definite TB diagnosis (culture and/or PCR positive for Mycobacterium tuberculosis; 47%, 71%, 72% and 40%, p<0.0001) and MDR-TB prevalence (34%, 3%, 3% and 11%, p <0.0001 among those with DST results). The history of injecting drug use [adjusted OR (aOR) = 2.03, (95% CI 1.00-4.09)], prior TB treatment (aOR = 3.42, 95% CI 1.88-6.22) and living in EE (aOR = 7.19, 95% CI 3.28-15.78) were associated with MDR-TB. For 569 patients with available DST, the initial TB treatment contained ≥3 active drugs in 64% of patients in EE compared with 90-94% of patients in other regions (Figure 1a). Had the patients received initial therapy with standard therapy [Rifampicin, Isoniazid, Pyrazinamide, Ethambutol (RHZE)], the corresponding proportions would have been 64% vs. 86-97%, respectively (Figure 1b). CONCLUSIONS In EE, TB/HIV patients had poorer exposure to cART, less often a definitive TB diagnosis and more often MDR-TB compared to other parts of Europe and LA. Initial TB therapy in EE was sub-optimal, with less than two-thirds of patients receiving at least three active drugs, and improved compliance with standard RHZE treatment does not seem to be the solution. Improved management of TB/HIV patients requires routine use of DST, initial TB therapy according to prevailing resistance patterns and more widespread use of cART.

Contrasts, Contacts, and Interconnections — Tel Kinrot as an Early Iron Age Key Site in the Northern Jordan Rift Valley at the Dawn of the 1st Millennium BCE

Ancient Kinneret (Tēl Kinrōt [Hebrew]; Tell el-ʿOrēme [Arabic]) is located on a steep limestone hill on the northwestern shores of the Sea of Galilee (2508.7529 [NIG]). The site, whose settlement history began sometime during the Pottery-Neolithic or the early Chalcolithic period, is emerging as one of the major sites for the study of urban life in the Southern Levant during the Early Iron Age (c. 1130–950 BCE). Its size, accessibility by major trade routes, and strategic location between different spheres of cultural and political influence make Tēl Kinrōt an ideal place for studying the interaction of various cultures on urban sites, as well as to approach questions of ethnicity and regionalism during one of the most debated periods in the history of the ancient Levant. The paper will briefly discuss the settlement history of the site during the Early Iron Age. However, the main focus will lie on the material culture of the late Iron Age IB city that rapidly evolved to a regional center during the transition from the 11th to the 10th century BCE. During this period, ancient Kinneret features a multitude of cultural influences that reach from Egypt via the Central Hill Country until the Northern parts of Syria and the Amuq region. While there are indisputably close ties with the ‘Aramaean’ realm, there are also strong indications that there were – at the same time – vivid socio-economic links with the West, i.e. the Southern and Northern Mediterranean coasts and their hinterland. It will be argued that the resulting ‘cultural blend’ is a typical characteristic of the material culture of the Northern Jordan Rift Valley in the advent of the emerging regional powers of the Iron Age II.

CCL5/RANTES is a key chemoattractant released by degenerative intervertebral discs in organ culture.

Release of chemotactic factors in response to tissue damage has been described for different musculoskeletal tissues, including the intervertebral disc (IVD). This study investigated the chemoattractants that are released by induced degenerative IVDs and may be involved in recruiting mesenchymal stem cells (MSCs). Bovine caudal discs were cultured within a bioreactor and loaded under conditions that mimicked physiological or degenerative settings. Between days 4-6, medium was replaced by PBS, which was subsequently used for proteomic, ELISA and immunoprecipitation analyses of secreted chemokines and cytokines. A Boyden chamber assay was used to observe human MSC migration towards native and chemokine depleted media. Gene expression levels of chemokine receptors in human MSCs were analysed, and CCL5 was localised in bovine and human IVD by immunohistochemistry. Proteomic analysis revealed the presence of CCL5 and CXCL6 within conditioned media. Higher concentrations of CCL5 were found in the degenerative media, and a relationship was found between interleukin-1β and CCL5 concentration. Chemokine immunoprecipitation showed that MSCs had a significantly reduced chemotactic migration towards CCL5-immunoprecipitated and CCL5/CXCL6 co-immunoprecipitated media, whilst CXCL6 depletion did not change MSC chemotaxis. MSCs showed a significant increase in mRNA expression of the CCL5 receptors, CCR1 and CCR4, upon culture in degenerative media. Furthermore, CCL5 was identified in bovine and human disc tissue by immunohistochemistry. Hence, CCL5 may be a key chemoattractant that is produced and released by the intervertebral disc cells. Therefore, these factors could be used to enhance stem/progenitor cell mobilisation in regenerative therapies for early stages of disc degeneration.

Trading Values in Early Modern Antwerp

In his Descrittione di tutti i Paesi Bassi of 1567, the Italian merchant and humanist Ludovico Guicciardini described Antwerp as the warehouse of the world where all kinds of commodities were traded and displayed. Early modern Antwerp’s pre-eminent position depended upon links between material trade and exchange and the circulation of information, knowledge and beliefs. In this multidisciplinary volume of the NKJ, articles by leading scholars in the fields of art and material culture, literature and history explore ways in which value was propagated in the city from its so-called golden age, before the Revolt of the Netherlands, far into the seventeenth century.

Social motility of African trypanosomes is a property of a distinct life-cycle stage that occurs early in tsetse fly transmission

The protozoan pathogen Trypanosoma brucei is transmitted between mammals by tsetse flies. The first compartment colonised by trypanosomes after a blood meal is the fly midgut lumen. Trypanosomes present in the lumen-designated as early procyclic forms-express the stage-specific surface glycoproteins EP and GPEET procyclin. When the trypanosomes establish a mature infection and colonise the ectoperitrophic space, GPEET is down-regulated, and EP becomes the major surface protein of late procyclic forms. A few years ago, it was discovered that procyclic form trypanosomes exhibit social motility (SoMo) when inoculated on a semi-solid surface. We demonstrate that SoMo is a feature of early procyclic forms, and that late procyclic forms are invariably SoMo-negative. In addition, we show that, apart from GPEET, other markers are differentially expressed in these two life-cycle stages, both in culture and in tsetse flies, indicating that they have different biological properties and should be considered distinct stages of the life cycle. Differentially expressed genes include two closely related adenylate cyclases, both hexokinases and calflagins. These findings link the phenomenon of SoMo in vitro to the parasite forms found during the first 4-7 days of a midgut infection. We postulate that ordered group movement on plates reflects the migration of parasites from the midgut lumen into the ectoperitrophic space within the tsetse fly. Moreover, the process can be uncoupled from colonisation of the salivary glands. Although they are the major surface proteins of procyclic forms, EP and GPEET are not essential for SoMo, nor, as shown previously, are they required for near normal colonisation of the fly midgut.

Otium et negotium. Reading processes and their cultural backgrounds in early Italian and German humanism

Reading and reading habits have radically changed in the digital age. Readers are no longer physically bound to textual objects and libraries, they deal with texts by copying, altering, and annotating them, and they mix established textual forms with other semiotic systems such as pictograms, icons and images. These circumstances also provoke a renewed research interest in the history of reading. In this talk, I will concentrate on reading processes as to how they were enacted and practised in early Italian and German humanism. I will start with some paradigmatic scenes described in Petrarch’s letters (among others the famous visit of the Mont Ventoux, where Petrarch, after having enjoyed a spectacular panorama, withdraws into the contemplative reading of St-Augustine). The transmission of Petrarch’s writings in humanist circles of Southern Germany (e.g. with the Schedel and Gossembrot families in Nurnberg, Augsburg and Strasburg) will then lead to specific reading practices documented in manuscripts that once belonged to coherent libraries and are nowadays spread all over Europe. In the case of the former tradesman and mayor Sigismund Gossembrot, complex habits of textual annotating and cross-referencing can be observed. The dichotomy of the Latin terms otium (‘rest’ and ‘leisure’) and negotium (‘activity’, but also ‘practice’, ‘negotiation’, ‘circulation of social energy’ in the sense of New Historicism) will be used as an ideal-type outline to describe the occurring processes of reading.

Refractions of Canada in European Literature and Culture

Ever since the first exploratory expeditions in the early modern period, North America has epitomized to Europeans a promise and the hope for the fulfilment of great expectations, be it of more freedom, greater wealth, social liberation or religious tolerance. While numerous features in this dialogic intercontinental relationship will hold true for North America in its entirety, the vast northern territories which we know as Canada today began to emerge early on as a specific iconic location in European mind-maps, and they definitely acquired a distinctive profile after the formation of the USA. As a rich source of cultural exchange and an important partner in political and economic cooperation Canada has come to occupy an important position in the cultural discourses of many European nations. It is these refractions and images of Canada which this volume thoroughly explores in European literature and culture. The contributions include literature, philosophy, language, life-writing and the concept of 'Heimat' (homeland) as well as the cultural impact of the World Wars. While there is an emphasis on literary texts, other fields of cultural representation are also included.

Female Imitatio Christi in early modernity – the search for strong virgins like St Wilgefortis

At first glance you think that this is Christ crucified. At a second glance, you recognize a woman hanging on a cross. This is not an invention of the 20th century but reaches back to history where we we can find women cross-dressed or even bearded as men. St Wilgefortis or St Uncumber was a bearded and crucified woman who was venerated widely in northern Europe during the fifteeneth and sixteenth centuries. Wilgefortis is a corruption of the term „virgo fortis“ („strong virgin“). She and other female saints were considered as „imitations of Christ“. The paper deals with the reasons why this saint became so popular and how even today ideas about such strong virgins which mirror androgynous symbolism live on in popular culture.
