TL;DR: A large-scale assessment suggests that experimental reproducibility in psychology leaves a lot to be desired, and correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.
Abstract: Reproducibility is a defining feature of science, but the extent to which it characterizes current research is unknown. We conducted replications of 100 experimental and correlational studies published in three psychology journals using high-powered designs and original materials when available. Replication effects were half the magnitude of original effects, representing a substantial decline. Ninety-seven percent of original studies had statistically significant results. Thirty-six percent of replications had statistically significant results; 47% of original effect sizes were in the 95% confidence interval of the replication effect size; 39% of effects were subjectively rated to have replicated the original result; and if no bias in original results is assumed, combining original and replication results left 68% with statistically significant effects. Correlational tests suggest that replication success was better predicted by the strength of original evidence than by characteristics of the original and replication teams.

TL;DR: Insight is provided into how obligate parasites with diverse life strategies arose from a once free-living phototrophic marine alga, and co-regulated with genes encoding the flagellar apparatus supporting the functional contribution of flagella to the evolution of invasion machinery.
Abstract: The eukaryotic phylum Apicomplexa encompasses thousands of obligate intracellular parasites of humans and animals with immense socio-economic and health impacts. We sequenced nuclear genomes of Chromera velia and Vitrella brassicaformis, free-living non-parasitic photosynthetic algae closely related to apicomplexans. Proteins from key metabolic pathways and from the endomembrane trafficking systems associated with a free-living lifestyle have been progressively and non-randomly lost during adaptation to parasitism. The free-living ancestor contained a broad repertoire of genes many of which were repurposed for parasitic processes, such as extracellular proteins, components of a motility apparatus, and DNA- and RNA-binding protein families. Based on transcriptome analyses across 36 environmental conditions, Chromera orthologs of apicomplexan invasion-related motility genes were co-regulated with genes encoding the flagellar apparatus, supporting the functional contribution of flagella to the evolution of invasion machinery. This study provides insights into how obligate parasites with diverse life strategies arose from a once free-living phototrophic marine alga.

TL;DR: Ozonation has been the most extensively reported and successfully implemented AOP at an industrial scale for effluent treatment or reuse within pulp and paper mills, although Fenton processes have actually addressed better oxidative results at a lab scale, but still need further development at a large scale.
Abstract: Paper industry is adopting zero liquid effluent technologies to reduce fresh water use and meet environmental regulations, which implies water circuits closure and the progressive accumulation of pollutants that must be removed before water re-use and final wastewater discharge. The traditional water treatment technologies that are used in paper mills (such as dissolve air flotation or biological treatment) are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies, such as advanced oxidation processes (AOPs), are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. A deep review of the current state of the art regarding the use of AOPs for the treatment of the organic load of effluents from the paper industry is herein addressed considering mature and emerging treatments for a sustainable water use in this sector. Wastewater composition, which is highly dependent of the raw materials being used in the mills, the selected AOP itself, and its combination with other technologies, will determine the viability of the treatment. In general, all AOPs have been reported to achieve good organics removal efficiencies (COD removal >40%; and about an extra 20% if AOPs are combined with biological stages). Particularly, ozonation has been the most extensively reported and successfully implemented AOP at an industrial scale for effluent treatment or reuse within pulp and paper mills; although Fenton processes (photo-Fenton particularly) have actually addressed better oxidative results (COD removal ≈65-75%) at lab scale, but still need further development at large scale.

TL;DR: Using a sample of 3,745 firms across manufacturing industries in the United States during the period 2001-2009, support is found for the moderation argument and less convincing support for mediation, suggesting that firms may not form interlocks necessarily to reduce uncertainty.
Abstract: We examine how uncertainty influences the performance effects of directorate interlocks. Our study offers a new perspective of directorate interlocks as mechanisms that enable firms to improve performance when confronted with greater uncertainty, suggesting that uncertainty positively moderates the interlock-performance relationship. This contrasts with the view based on resource dependence theory suggesting networks reduce uncertainty and enhance firm performance, implying that uncertainty mediates the interlock effect upon performance. Using a sample of 3,745 firms across manufacturing industries in the United States during the period 2001-2009, we find support for the moderation argument and less convincing support for mediation, suggesting that firms may not form interlocks necessarily to reduce uncertainty. Instead, firms may create interlocks to enable adaptation and enhance performance when confronted by uncertainty.

TL;DR: In this article, the relationship between experience in the CEO position of a different firm and the post-succession financial performance of the firm that they currently lead was investigated. And the results showed that experience is negatively related to firm performance.
Abstract: We sample CEOs of the 2005?S&P 500 corporations to look at the relationship between experience in the CEO position of a different firm and the post-succession financial performance of the firm that they currently lead. We find that experience in the CEO position is negatively related to firm performance. CEOs who directly move to their current CEO position from the previous one and those with job-specific experience in the same or related industry or at the helm of a previous company similar in size to the current one are associated with significantly lower post-succession performance than those without prior CEO experience. The results contribute to the literatures on CEO succession, the performance effect of job-specific experience, and the transferability of human capital.

TL;DR: The results suggest that while a trade-off between photosynthetic capacity at the leaf level and hydraulic function of xylem could be established across populations, it functions independently of the compromise between safety and efficiency of the hydraulic system with regard to water use at the interpopulation level.
Abstract: The aim of this study was to provide new insights into how intraspecific variability in the response of key functional traits to drought dictates the interplay between gas-exchange parameters and the hydraulic architecture of European beech (Fagus sylvatica L.). Considering the relationships between hydraulic and leaf functional traits, we tested whether local adaptation to water stress occurs in this species. To address these objectives, we conducted a glasshouse experiment in which 2-yearold saplings from six beech populations were subjected to different watering treatments. These populations encompassed central and marginal areas of the range, with variation in macro- and microclimatic water availability. The results highlight subtle but significant differences among populations in their functional response to drought. Interpopulation differences in hydraulic traits suggest that vulnerability to cavitation is higher in populations with higher sensitivity to drought. However, there was no clear relationship between variables related to hydraulic efficiency, such as xylem-specific hydraulic conductivity or stomatal conductance, and those that reflect resistance to xylem cavitation (i.e., Ψ12, the water potential corresponding to a 12% loss of stem hydraulic conductivity). The results suggest that while a trade-off between photosynthetic capacity at the leaf level and hydraulic function of xylem could be established across populations, it functions independently of the compromise between safety and efficiency of the hydraulic system with regard to water use at the interpopulation level.

TL;DR: The results suggest that both integrative mechanisms, joint decision making and joint sense making, affect performance although in different ways, including operational efficiency and innovation.
Abstract: Purpose – There are two major objectives in the research. First, the authors investigate the impact of knowledge integration in terms of joint decision-making and joint sense-making, on relational performance, including operational efficiency and innovation. Second, the authors examine the key antecedents that might facilitate knowledge integration: strategic supply management and trust. The paper aims to discuss these issues. Design/methodology/approach – This paper expands and tests theory drawing upon survey data from 133 buyer-supplier relationships (BSRs). The authors employed a two-step process of analysis to evaluate first the measurement model and then the structural model. The measurement model test built upon confirmatory factor analysis, while the structural model quality test built upon path analysis. Findings – The results suggest that both integrative mechanisms, joint decision making and joint sense making, affect performance although in different ways. This study also finds that while trus...

TL;DR: The authors found that self-comparisons with concrete, influential leaders of the past or present (self-to-exemplar comparisons) relate positively to motivation to lead, while the effect of comparison with more general representations of leaders is mediated through individuals' leadership self-efficacy perceptions.
Abstract: Drawing on social comparison and identity literature, we suggest that individuals' comparisons of themselves to their own standards of leadership relate to their leadership motivation. We propose and test a model of motivation to lead (MTL) based on two types of self-to-leader comparisons: self-to-exemplar and self-to-prototype comparisons with respect to affiliation. In our main study, using data from a sample of 180 executives, we apply structural equation models to test our predictions. We find that self-comparisons with concrete, influential leaders of the past or present (self-to-exemplar comparisons) relate positively to MTL. We also find that self-comparisons with more general representations of leaders (self-to-prototype comparisons in affiliation) relate to MTL. Whereas the effect of self-to-exemplar comparisons is mediated through individuals' leadership self-efficacy perceptions, the effect of self-to-prototype comparisons is not. We replicate these findings in three follow-up studies using different research designs. We derive implications for theory and practice.

TL;DR: In this article, the authors present a new data set on voting rules and establish the broader importance of voting rules by illustrating how they help states achieve four core institutional design objectives: control, compliance, responsiveness, and effective membership.
Abstract: This article presents a new data set on one of the most visible features of institutional design - voting rules. The data set covers 266 intergovernmental organizations (IGOs) that vary in size and substantive scope and includes data on IGO issue area and founding membership characteristics that complement the measures on voting rules. The article outlines the characteristics and categorization of voting rules in the data set and establishes the broader importance of voting rules by illustrating how they help states achieve four core institutional design objectives: control, compliance, responsiveness, and effective membership. The utility of the data set and patterns in the relationships between its variables are identified through the evaluation of preliminary propositions connecting institutional context and voting rule selection. The preliminary findings emerging from this analysis establish a platform for further analyses of voting rules in IGOs, as well as other dimensions of the design and function of IGOs.

TL;DR: This article found that pay dispersion had an inverted U-shaped effect on employee participation, which in turn enhanced innovation and had a positive effect on voluntary turnover, which impaired innovation, and revealed the mediation mechanisms of employee participation and voluntary turnover in the relationship between pay disparity and organizational innovation.
Abstract: Building on social comparison theory, we posit that a firm’s pay dispersion affects its innovation through employee participation and voluntary turnover. By analyzing data collected at both employee and organizational levels from 1419 firms, we found that pay dispersion had an inverted U-shaped effect on employee participation, which in turn enhanced innovation. Pay dispersion had a positive effect on voluntary turnover, which in turn impaired innovation. These findings contribute to research on economic inequity by revealing the mediation mechanisms of employee participation and voluntary turnover in the relationship between pay dispersion and organizational innovation.

TL;DR: It is found that contract duration is indeed associated with structural and positional embeddedness of participant firms, with the relational embeddeds of the buyer-seller dyad, and with the duration of other contracts to which it is connected through common firms.
Abstract: This paper presents new evidence on the role of embeddedness in predicting contract duration in the context of Information Technology (IT) Outsourcing. Contract duration is a strategic decision that aligns interests of clients and vendors, providing the benefits of business continuity to clients and incentives to undertake relationship specific investments for vendors. Considering the salience of this phenomenon, there has been limited empirical scrutiny into how contract duration is awarded. We posit that clients and vendors obtain two benefits from being embedded in an inter-organizational network. First, the learning and experience accumulated from being embedded in client-vendor network could mitigate the challenges in managing longer-term contracts. Second, the network serves as a reputation system that can stratify vendors according to their trustworthiness and reliability, which is important in longer term arrangements. We analyze a dataset of 22039 outsourcing contracts implemented between 1989 and 2008. We find that contract duration is indeed associated with structural and positional embeddedness of participant firms, with the relational embeddedness of the buyer-seller dyad and with the duration of other contracts to which it is connected through common firms. Given the nature of our data, identification using traditional OLS based approaches is difficult given the unobserved errors being clustered along two non-nested dimensions and the autocorrelation in a firm’s decision (here the contract) with those of contracts in its reference group. We employ a multi-way cluster robust estimation and a network auto-regressive estimation to address these issues. Implications for literature and practice are discussed.

TL;DR: In this paper, the performance budget of a local government organization, in this case a province in the Netherlands, can be attuned to the specific task characteristics of the programmes in these budgets.
Abstract: This paper shows how the performance budget of a local government organization, in this case a province in the Netherlands, can be attuned to the specific task characteristics of the programmes in these budgets. Three ways of alignment are suggested: differentiating between standardized and complex programmes; focussing on the politically most relevant programmes in order to avoid information overload; and distinguishing between the types of performance information in terms of the role of the province in the programme (facilitator versus executor) and the stage in the policy making cycle (policy development, policy elaboration or policy execution). These suggestions challenge the generally straightforward NPM rationale of performance budgeting, in which standardized outputs are directly related to resources. Our empirical research shows on the one hand that the redesigned programme budget based on the above principles received substantial approval of its users, i.e., the provincial councillors. On the other hand, as regards the use of this programme budget the picture is rather diffuse, i.e., the majority of the councillors indicate that they use the information rather intensively, but its formal use in official Council and Council committee meetings remains limited.

TL;DR: The arrival of new scientific personnel is likely to exert stronger positive effects on the performance of incumbent scientists with shorter (cf. longer) organizational tenure; in addition, academic departments with less diversified expertise and with higher levels of internal collaborations likely reap greater benefits from learning by hiring.
Abstract: This study investigates the effects of scientists’ inbound mobility on the research performance of incumbent scientists in an academic setting. The theoretical framework integrates insights from learning theory and social comparison theory to suggest two main mechanisms behind these effects: localized learning and social comparison. The authors propose several hypotheses about the conditions that might intensify or weaken such effects. Specifically, the arrival of new scientific personnel is likely to exert stronger positive effects on the performance of incumbent scientists with shorter (cf. longer) organizational tenure; in addition, academic departments with less diversified expertise and with higher levels of internal collaborations likely reap greater benefits from learning by hiring. The empirical findings, based on a longitudinal analysis of a sample of 94 U.S. academic chemical engineering departments, provide empirical support for these contentions.

TL;DR: In this paper, the authors followed a secondary-care cohort of patients with bipolar disorder (BD) and found that patients with BD spent only half of their time euthymic.
Abstract: Objectives The long-term outcome of bipolar disorder (BD) has been extensively investigated. However, previous studies may be biased towards hospitalized patients with bipolar I disorder (BD-I), and generalizability to the current treatment era remains uncertain. In this naturalistic study, we followed a secondary-care cohort of patients with BD. Methods In the Jorvi Bipolar Study, 191 patients with BD-I and bipolar II disorder (BD-II) were followed using a life-chart method. Interviews were conducted at six months, 18 months, and five years. Time to full remission, time to first recurrence, total time ill, their predictors, and BD-I versus BD-II differences were investigated among the 151 patients remaining in follow-up. Results Nearly all subjects recovered from the index episode, but almost all (90%) had a recurrence, and most had multiple recurrences. The patients spent about one-third of their time in illness episodes and 15% of their time with subthreshold symptoms; half of the time they were euthymic. After controlling for confounders, no difference in time spent in depressive states between patients with BD-I and BD-II persisted. Among patients with a depressive index phase, cluster C personality disorders [hazard ratio (HR) = 0.452, p = 0.040] and higher 17-item Hamilton Depression Scale score (HR = 0.951, p = 0.022) predicted longer time to remission, whereas lifetime psychotic symptoms (HR = 2.162, p = 0.016) predicted shorter time to first recurrence. Conclusions Among patients with BD, chronicity as uninterrupted persistence of illness was rare, but multiple recurrences were the norm. Patients with BD spent only half of their time euthymic. Patients with BD-I and BD-II may differ little in proneness to depressive states. Severity of depression, cluster C personality disorders, and psychotic symptoms predicted outcome.

TL;DR: This paper examined the role of Chinese characteristics in the emergence of three accounting regulations for foreign invested firms (FIFs) as part of China's recent transformation to become part of the "world order".
Abstract: Drawing on actor network theory (ANT), this paper analyses the role of Chinese characteristics in the emergence of three accounting regulations for foreign invested firms (FIFs) as part of China’s recent transformation to become part of the “world order”. The paper examines how international accounting standards (IAS) and existing Chinese accounting were translated into new regulations for FIFs, and how these translations were shaped by malleable interpretations of Chinese characteristics. Chinese characteristics were a discursive obligatory passage point (OPP) rendered malleable through cognition and the sanctions of political authority to suit the interests of actors seeking to produce new accounting regulations. Chinese characteristics were a signifier that carved out a space for local networks to attain their identity and retain some measure of independence from global networks, shaped the construction of each accounting regulation for FIFs into an attractive package, and influenced the adaptation and transformation of those elements of Western accounting that arrived into China. In turn, IAS became part of the discursive field on accounting regulation that helped mediate the shifts in the interpretation of Chinese characteristics over time.

TL;DR: In this paper, the authors examine how self-construal and goal type are conceptually linked and jointly impact consumer behavior and find that attainment (maintenance) goals can be more motivating for participants with a more independent (interdependent) self-consistency and that differences in salient knowledge about pursuing the goals are one potential mechanism underlying this effect.
Abstract: This research examines how self-construal (i.e., independent vs. interdependent) and goal type (i.e., attainment vs. maintenance) are conceptually linked and jointly impact consumer behavior. The results of five experiments and one field study involving different operationalizations of self-construal and goal pursuit activities suggest that attainment (maintenance) goals can be more motivating for participants with a more independent (interdependent) self-construal and that differences in salient knowledge about pursuing the goals are one potential mechanism underlying this effect. This interaction effect was found within a single culture, between cultures, when self-construal was experimentally manipulated or measured, and when potential confounding factors like regulatory focus were controlled for. The effect was also found to impact consumer behavior in real life—self-construal, as reflected by the number of social ties consumers had, impacted the likelihood that they opted to reduce versus maintain their bodyweight. Further, after setting their goal, consumers who were more independent exhibited more (less) motivation, as measured by the amount of money they put at stake, when their goal was weight reduction (maintenance). These findings shed light on the relationship between self-construal and goal type, and offer insights, to both consumers and managers, on how to increase motivation for goal pursuit.

TL;DR: In this article, the authors provide evidence that firms considering entering new markets are more likely to appoint directors with experience in those markets; and subsequently, they show that directors' market experience increases the likelihood of new-market entry.
Abstract: In this study we provide evidence that firms considering entering new markets are more likely to appoint directors with experience in those markets; and subsequently, we show that directors' market experience increases the likelihood of new-market entry. Moreover, we explore the presence of constraints in both, acquiring experienced directors and utilizing their experience. Specifically, we find that experienced directors are less likely to join firms with financial restatements in the recent past as well as firms with a lower status than the firms where they currently serve. In addition, we find that interlocking directors' experience is less likely to lead to new-market entry for firms that lack new-product development experience and that exhibit a high level of market overlap with interlocked firms.

TL;DR: In this paper, the authors investigated the role of university and PRO-oriented seed funds (USFs) as instruments for addressing funding gaps and facilitating the commercialization of academic technologies.
Abstract: This work investigates the role of university and PRO-oriented seed funds (USFs)—VC funds with an explicit mission to make investments in academic spin-offs and support technology transfer—as instruments for addressing funding gaps and facilitating the commercialization of academic technologies. We first offer an overview of USFs in Europe, highlighting their heterogeneity and principal characteristics. Second, we exploit a unique data set of 1,497 start-ups (including 733 USF-backed start-ups and another 764 start-ups backed by other VC funds) to analyze how USF-backed companies perform in terms of exit rates, staging, and syndication levels when compared with non-USF-backed companies. Empirical evidence suggests that USF-backed companies perform better in staging and syndication but worse in exit rates. Moreover, our analyses show that, within the group of USF-backed companies, the ones that can attract more follow-on funding and investors are those financed by USFs that are internally managed by a universities/PROs and are linked to universities with high scientific rankings.

TL;DR: In this paper, the authors build on existing family business research conducted in the European context to portray Europe as a critically important context for extending our knowledge on important family business topics, and also count on the view of the Secretary General of European Family Businesses to enhance our understanding of the institutional frameworks that can benefit family businesses in the EU zone.
Abstract: Family businesses are the most ubiquitous form of business organisation in Europe. Yet, most of the existing family business literature has been developed within a North American context. This introductory article builds on existing family business research conducted in the European context to portray Europe as a critically important context for extending our knowledge on important family business topics. It also counts on the view of the Secretary General of European Family Businesses to enhance our understanding of the institutional frameworks that can benefit family businesses in the EU zone. Specifically, the content of the article discusses some contextual factors that might affect the broadness, diversity, uniqueness and growth potential of family business research; identifies some of the interesting research questions that emerge from examining the distinctive traits of the European context; and stimulates further family business work in the European context and comparison with studies conducted in different geographies.
