The history of the General Agreement on Tariffs and Trade negotiations is full of anecdotes on missed deadlines, failed ministerial conferences, and brinkmanship situations. Tactics such as walking away from the table or sleep-depriving night sessions are legendary in the context of attempting to overcome impasse in negotiations. This article traces and explains the recurrent deadlock in the Doha Round negotiations. It identifies four structural/contextual factors – ideas, institutions, interests, and information – as necessary for understanding and anticipating potential deadlocks. The article also offers a definition of deadlock, and discusses a set of factors highlighted in the international relations literature that explain the existence and persistence of deadlock. With the help of game theory, it then illustrates the challenges faced by actors during trade negotiations. The article concludes by outlining two general scenarios for the Doha Development Agenda and discusses their implications for the World Trade Organization.

BACKGROUND Cytomegalovirus (CMV) replication has been associated with more risk for solid organ graft rejection. We wondered whether this association still holds when patients at risk receive prophylactic treatment for CMV. METHODS We correlated CMV infection, biopsy-proven graft rejection, and graft loss in 1,414 patients receiving heart (n=97), kidney (n=917), liver (n=237), or lung (n=163) allografts reported to the Swiss Transplant Cohort Study. RESULTS Recipients of all organs were at an increased risk for biopsy-proven graft rejection within 4 weeks after detection of CMV replication (hazard ratio [HR] after heart transplantation, 2.60; 95% confidence interval [CI], 1.34-4.94, P<0.001; HR after kidney transplantation, 1.58; 95% CI, 1.16-2.16, P=0.02; HR after liver transplantation, 2.21; 95% CI, 1.53-3.17, P<0.001; HR after lung transplantation, 5.83; 95% CI, 3.12-10.9, P<0.001. Relative hazards were comparable in patients with asymptomatic or symptomatic CMV infection. The CMV donor or recipient serological constellation also predicted the incidence of graft rejection after liver and lung transplantation, with significantly higher rates of rejection in transplants in which donor or recipient were CMV seropositive (non-D-/R-), compared with D- transplant or R- transplant (HR, 3.05; P=0.002 for liver and HR, 2.42; P=0.01 for lung transplants). Finally, graft loss occurred more frequently in non-D- or non-R- compared with D- transplant or R- transplant in all organs analyzed. Valganciclovir prophylactic treatment seemed to delay, but not prevent, graft loss in non-D- or non-R- transplants. CONCLUSION Cytomegalovirus replication and donor or recipient seroconstellation remains associated with graft rejection and graft loss in the era of prophylactic CMV treatment.

BACKGROUND Polymorphisms in the interferon-λ (IFNL) 3/4 region have been associated with reduced hepatitis C virus clearance. We explored the role of such polymorphisms on the incidence of CMV infection in solid-organ transplant (SOT) recipients. METHODS Caucasian patients participating in the Swiss Transplant Cohort Study in 2008-2011 were included. A novel functional TT/-G polymorphism (rs368234815) in the CpG region upstream of IFNL3 was investigated. RESULTS A total of 840 SOT recipients at risk for CMV were included, among whom 373 (44%) received antiviral prophylaxis. The 12-months cumulative incidence of CMV replication and disease were 0.44 and 0.08, respectively. Patient homozygous for the minor rs368234815 allele (-G/-G) tended to have a higher cumulative incidence of CMV replication (SHR=1.30 [95%CI 0.97-1.74], P=0.07) compared to other patients (TT/TT or TT/-G). The association was significant among patients followed by a preemptive approach (SHR=1.46 [1.01-2.12], P=0.047), especially in patients receiving an organ from a seropositive donor (D+, SHR=1.92 [95%CI 1.30-2.85], P=0.001), but not among those who received antiviral prophylaxis (SHR=1.13 [95%CI 0.70-1.83], P=0.6). These associations remained significant in multivariate competing risk regression models. CONCLUSIONS Polymorphisms in the IFNL3/4 region influence susceptibility to CMV replication in SOT recipients, particularly in patients not receiving antiviral prophylaxis.

This study analyzed the influence of the occupational context on the conceptualization of career satisfaction measured by the career satisfaction scale (CSS). In a large sample of N ¼ 729 highly educated professionals, a cross-occupational (i.e., physicians, economists, engineers, and teachers) measurement invariance analysis showed that the CSS was conceptualized according to occupational group membership, that is, 4 of the 5 items of the scale showed measurement noninvariance. More specifically, the relative importance, the response biases, and the reliabilities associated with different career satisfaction content domains measured by the CSS (i.e., achieved success, overall career goals, goals for advancement, goals for income, and goals for development of new skills) varied by occupational context. However, results of a comparison between manifest and latent mean differences between the occupational groups revealed that the observed measurement noninvariance did not affect the estimation of mean differences.

The present study analyzed (a) gender differences in the gender composition (i.e., the proportion of male to female contacts) of professional support networks inside and outside an individual’s academic department and (b) how these differences in gender composition relate to subjective career success (i.e., perceived career success and perceived external marketability). Results showed that the networks’ gender composition is associated with subjective career success. Men’s networks consist of a higher proportion of male to female supporters, which, in turn, was positively related to subjective career success. Additional analyses revealed that the findings could not be accounted for by alternative factors, such as network size, networking behaviors, and career ambition.

Das Career Futures Inventory (CFI; Rottingaus, Day & Borgen, 2005) erfasst die drei laufbahnbezogenen Zukunftsfaktoren career adaptability (Berufliche Anpassungsfähigkeit), career optimism (Beruflicher Optimismus) und knowledge of job market (Arbeitsmarktwissen). Die Ziele dieser Studie waren (a) eine deutschsprachige Version des CFIs zu konstruieren und (b) an zwei Stichproben mit Erwerbstätigen mittels (c) unterschiedlicher Indikatoren des Berufserfolgs und anhand von Persönlichkeitseigenschaften zu validieren. Es konnte in beiden Stichproben (N1 = 153; N2 = 110) die 3-faktorielle Struktur des CFIs nachgewiesen werden. Zudem konnten Annahmen zur konvergenten und diskriminanten Validität in beiden Stichproben bestätigt werden, da die CFI-Faktoren in erwarteter Richtung mit Berufserfolg (z. B. Beförderungen, Karrierezufriedenheit) bzw. Persönlichkeitseigenschaften (d. h. Big Five) korrelierten bzw. nicht korrelierten. Eine Analyse der inkrementellen Validität zeigte, dass Arbeitsmarktwissen zusätzliche Varianz beim Gehalt über Kontrollvariablen und Persönlichkeit hinaus erklärte. Hinsichtlich Karrierezufriedenheit war dies für beruflichen Optimismus der Fall. Diese Validierungsstudie ermöglicht den Einsatz des CFIs im deutschsprachigen Raum.

Researchers have claimed that high quality of supervisor–employee relationships (i.e., leader– member exchange; LMX) fosters creativity at work. Moreover, researchers have acknowledged that this relationship is not clear-cut but rather complex. The present study focused on the moderating role of job autonomy in the LMX-creative work involvement relationship. Longitu-dinal field survey data (N = 144) collected in a high-technology firm revealed a positive asso-ciation between LMX and creative work involvement and confirmed our assumptions on the moderating role of job autonomy. The positive relationship between LMX and creative work involvement was stronger when employees experienced greater job autonomy. Our findings point to the importance of considering the interplay of both, the leader–member relationship and job design issues for increasing employees' creative work involvement.

The aim of the present paper is twofold. We first give an overview of the multi-faceted construct of career success with its “objective” (real attainments) and “subjective” (perceived attainments) components and with the different methodologies measuring them (“subjectivist” vs. “objectivist” approaches). We also discuss the relationship between the different components of career success as revealed in the literature. Our second aim is to show that the interrelationship between the different facets of career success varies with the employment context. We analyze subjective and objective career success measures collected from professionals working either in the private sector, in the public sector, or that are self-employed. Our findings show that objective success and subjective success are more closely related in the private and self-employment sectors than in the public sector. Moreover, the interrelationship between objective and subjective success varies with the specific subjective success measure chosen. It is stronger for an “other-referent” subjective success measure than for a “self-referent” subjective success measure. Conclusions regarding the measurement of career success as well as regarding the relevance of subjective success for studying occupational careers are drawn.

The present research analyses the adequacy of the widely used Career Satisfaction Scale (CSS; Greenhaus, Parasuraman, & Wormley, 1990) for measuring change over time. We used data of a sample of 1,273 professionals over a 5-year time period. First, we tested longitudinal measurement invariance of the CSS. Second, we analysed changes in career satisfaction by means of multiple indicator latent growth modelling (MLGM). Results revealed that the CSS can be reliably used in mean change analyses. Altogether, career satisfaction was relatively stable over time; however, we found significant variance in intra-individual growth trajectories and a negative correlation between the initial level of and changes in career satisfaction. Professionals who were initially highly satisfied became less satisfied over time. Theoretical and practical implications with respect to the construct of career satisfaction and its development over time (i.e., alpha, beta, and gamma change) are discussed.

While previous research has mainly emphasised the importance of leader–member exchange (LMX) to job satisfaction, there is a lack of research on reciprocal relationships between job satisfaction and LMX. In this study, we not only suggest that good LMX increases job satisfaction, but that job satisfaction can also enhance high-quality supervisor–employee relationships. A full cross-lagged panel analysis was used to test reciprocal relationships between LMX and job satisfaction. Employees (N= 279) of a large information technology company filled out questionnaires at two times, with a time lag of 3 months. In line with our predictions, findings revealed a positive relationship between LMX and job satisfaction both at Time 1 and Time 2. Moreover, LMX at Time 1 predicted the increase of job satisfaction at Time 2, and job satisfaction at Time 1 predicted the increase of LMX at Time 2. The results demonstrate the need to consider reciprocal relationships between job satisfaction and LMX when explaining employees' workplace outcomes. Our findings are discussed in terms of positive psychology theory.

The protean and boundaryless career attitudes have gained special attention during the past years. Aprotean career attitude implies that aperson strives towards adevelopmental progression and self-fulfillment; aboundaryless career attitude is characterized by ahigh physical and/or psychological mobility. The aim of the present paper is twofold: First, we want to empirically investigate the relationship between protean and boundaryless career attitudes and subjective (i.e., career satisfaction and success in comparison with colleagues) and objective (i.e., promotions and salary) career success. Second, we want to integrate research on protean and boundaryless career attitudes with research on predictors of career success. We analyze the career attitudes-career success relationship with asample of 116 professionals. Our findings suggest that components of the protean career attitude are rather more related with subjective career success and that components of the boundaryless career attitude are more related with objective career success. Conclusions regarding the relevance of career attitudes for career success are drawn.

People are increasingly in search for meaning in their work and private life. They want to increase their self-awareness and reach personal fulfillment. People who are not able to cope with life‘s challenges often suffer from burnout, anxiety and depression. Consequently, the construct of calling becomes more and more important in the occupational context because of its positive consequences regarding numerous work (e.g. organizational commitment) and non-work-related outcomes (e.g. depression, life satisfaction) for individuals as well as for organizations. Building on first promising findings, the aim of the following chapter is to investigate the association of experiencing a calling in one‘s job and burnout (here defined as psychological phenomenon of prolonged exhaustion and disengagement at work, cf., Maslach, Schaufeli, & Leiter, 2001). Our findings suggest that experiencing one‘s work as a calling is negatively related to burnout. Especially with regard to the sub-dimension of disengagement, experiencing a calling turned out to be a protective factor. Further, the burnout sub-dimension of disengagement mediated the relationship between the experience of a calling and job satisfaction. Implications for further research and health-related preventive strategies are discussed.
