As the nature of information systems (IS) has evolved from primarily standalone, to enterprise, and distributed applications, the need for a better understanding of collective IS use has become a research and practical necessity. In view of contributing to this understanding, we conceptually define collective IS use as a unit level construct, rooted in instances of individual-level IS use within the context of a common work process. Its emergence from the individual to the unit level is shaped by different configurations of task, user, and system interdependence between instances of individual-level IS use. On the basis of this definition, we propose a typology of collective IS use that comprises four ideal types, namely siloed use, processual use, coalesced use, and networked use. For each ideal type, we theorize on the emergence process from the individual to the unit level and we consider the measurement implications for each.

Both reliability and independence of global climate model (GCM) simulation are essential for model selection to generate a reasonable uncertainty range of dynamical downscaling simulations. In this study, we evaluate the performance and interdependency of 37 GCMs from the Coupled Model Intercomparison Project Phase 6 (CMIP6) in terms of seven key large-scale driving fields over 14 CORDEX domains. A multivariable integrated evaluation method is used to evaluate and rank the models’ ability to simulate multiple variables in terms of their climatological mean and interannual variability. The results suggest that the model performance varies considerably with seasons, domains, and variables evaluated, and no model outperforms in all aspects. However, the multi-model ensemble mean performs much better than almost all models. Among 37 CMIP6 models, the MPI-ESM1-2-HR and FIO-ESM-2-0 rank top two due to their overall good performance across all domains. To measure the model interdependency in terms of multiple fields, we define the similarity of multivariate error fields between pairwise models. Our results indicate that the dependence exists between most of the CMIP6 models, and the models sharing the same idea or/and concept generally show less independence. Furthermore, we hierarchically cluster the top 15 models with good performance based on the similarity of multivariate error fields to identify relatively independent models. Our evaluation can provide useful guidance on the selection of CMIP6 models based on their performance and relative independence, which helps to generate a more reliable ensemble of dynamical downscaling simulations with reasonable inter-model spread.

Cascading effects and cascading disasters are emerging fields of scientific research. The widespread diffusion of functional networks increases the complexity of interdependent systems and their vulnerability to large-scale disruptions. Although in recent years studies of interconnections and chain effects have improved significantly, cascading phenomena are often associated with the “toppling domino metaphor”, or with high-impact, low-probability events. This paper aimed to support a paradigm shift in the state of the art by proposing a new theoretical approach to cascading events in terms of their root causes and lack of predictability. By means of interdisciplinary theory building, we demonstrate how cascades reflect the ways in which panarchies collapse. We suggest that the vulnerability of critical infrastructure may orientate the progress of events in relation to society’s feedback loops, rather than merely being an effect of natural triggers. Our conclusions point to a paradigm shift in the preparedness phase that could include escalation points and social nodes, but that also reveals a brand new field of research for disaster scholars.

This article contributes to understandings of the conviviality which has dominated recent sociological approaches to urban multiculture. The article argues for conviviality’s conceptual extension by reference to recent rethinking of community as a profound sociality of ‘being with’ and a culture of urban practice. The article draws from a qualitative dataset examining sustained encounters of cultural difference and the relationships within social leisure organizations in three different English urban geographies. The article explores how the elective coming together of often ethnically diverse others, over time, in places, to do leisure ‘things’ meant these organizations could work as generative spaces of social interaction and shared practice through and in contexts of urban difference. The article concludes that putting conviviality as ‘connective interdependencies’ into dialogue with community as ‘being in common’ develops their sociological and explanatory power and counters the reductions and limitations that are associated with both concepts.

Photorespiration is frequently considered a wasteful and inefficient process. However, mutant analysis demonstrated that photorespiration is essential for recycling of 2-phosphoglycolate in C₃ and C₄ land plants, in algae, and even in cyanobacteria operating carboxysome-based carbon (C) concentrating mechanisms. Photorespiration links photosynthetic C assimilation with other metabolic processes, such as nitrogen and sulfur assimilation, as well as C₁ metabolism, and it may contribute to balancing the redox poise between chloroplasts, peroxisomes, mitochondria and cytoplasm. The high degree of metabolic interdependencies and the pleiotropic phenotypes of photorespiratory mutants impedes the distinction between core and accessory functions. Newly developed synthetic bypasses of photorespiration, beyond holding potential for significant yield increases in C₃ crops, will enable us to differentiate between essential and accessory functions of photorespiration.

Greater interdependence is often taken to require more global governance, but the logic requires scrutiny. Cross-border spillovers do not always call for international rules. The canonical cases for global governance are based on two sets of circumstances: global commons and “beggar-thy-neighbor” (BTN) policies. The world economy is not a global commons (outside of climate change), and much of our current discussions deal with policies that are not true BTNs. Some of these are beggar-thyself policies; others may produce domestic benefits, addressing real market distortions or legitimate social objectives. The case for global governance in such policies, I will argue, is very weak, and possibly outweighed by the risk that global oversight or regulation would backfire. While these policy domains are certainly rife with failures, such failures arise not from weaknesses of global governance, but from failures of national governance and cannot be fixed through international agreements or multilateral cooperation. I advocate a mode of global governance that I call “democracy-enhancing global governance,” to be distinguished from “globalization-enhancing global governance.”

Background Patients with prostate cancer (PC) and their spouses are confronted with several treatment-related and psychosocial challenges that can reduce their health-related quality of life (HRQoL). Patients with advanced PC (aPC) and their spouses are at highest risk for psychological distress and show lower HRQoL compared with couples in other phases. The aim of this study was to investigate the psychological interdependencies between HRQoL and anxiety, fear of progression (FoP), and depression in patients with aPC and their spouses. Methods Ninety-six heterosexual couples with aPC participated in this cross-sectional study. Patients and spouses provided information about anxiety and depression (Patient Health Questionnaire-4), fear of progression (short form of the Fear of Progression Questionnaire), and HRQoL (EORTC QoL-C30, version 3). Psychological interdependencies were analyzed with various actor-partner interdependence models using structural equation modeling. Results Anxiety, FoP, and depression were significant predictors of HRQoL for patients with aPC and their spouses (actor effects). Spouses’ anxiety and FoP were negatively associated with patients’ HRQoL (partner effects), showing that patients’ HRQoL is associated with their own and their spouses’ anxiety and FoP. No partner effect was revealed between depression and HRQoL in the patients or spouses. Conclusions The resulted partner effects between spouses and patients underline the importance of considering HRQoL in patients with aPC from a dyadic perspective. It is important that physicians explore patients’ and spouses’ needs and psychological burden to offer support and access to psycho-oncological services. Future studies are needed to investigate the effects of suitable interventions on spouses’ anxiety and FoP.

Self-serving leadership is a form of unethical leadership behavior that has destructive effect on its targets and the overall organization. Adopting a social cognition perspective, this study expands our knowledge of its adverse effect and the way to mitigate the effect. Integrating two sub-theories of social cognition (social information processing and social learning), we propose a theoretical model wherein self-serving leadership hinders team creativity through psychological safety as well as knowledge hiding, with task interdependence acting as a contextual condition. Results from a sample of 107 R&D teams revealed that self-serving leadership not only reduced team psychological safety, but also induced team knowledge hiding, both of which ultimately affected team creativity. The presence of high task interdependence buffered the destructive effect of self-serving leadership on team creativity via team psychological safety as well as the indirect effect via knowledge hiding.

Research Summary: This paper extends the relational view to offer a dynamic perspective on the factors that drive value creation and value capture over the alliance life cycle. We argue that access to complementary resources provides an initial rationale for forming alliances, but benefits from complementarity can attenuate over time. Indeed, viewed dynamically, factors that often lead to higher value creation—informal trust, repeated ties, customized assets—may also lead to diminished alliance performance. We highlight interdependence between the complementary resources of partners as the critical factor determining the pattern of alliance value creation, notably how quickly alliances generate value and how quickly they are likely to dissolve. We identify factors, both internal and external to the alliance, that trigger diminished value creation and increased competition for value capture among partners. Managerial Summary: The “relational view” perspective has shown that firms create value in alliances when they identify partners with complementary resources, when they build high levels of informal trust and they share knowledge and make investments that are customized to the partner. The level of resource interdependence in alliances determines how quickly alliances can reach their potential in value creation and how quickly they are likely to dissolve. Viewed dynamically, factors that often lead to higher value creation—like informal trust, repeated ties, customized assets—may also lead to diminished alliance performance. Finally, a number of factors both internal to and external to an alliance may trigger competition between the partners within an alliance to capture the value created by the alliance and also diminish the value created within the alliance.

Breast cancer is the most frequent cancer among women, and metastases in distant organs are the leading cause of the cancer‐related deaths. While survival of early‐stage breast cancer patients has increased dramatically, the 5‐year survival rate of metastatic patients has barely improved in the last 20 years. Metastases can arise up to decades after primary tumor resection, hinting at microenvironmental factors influencing the sudden outgrowth of disseminated tumor cells (DTCs). This review summarizes how the environment of the most common metastatic sites (lung, liver, bone, brain) is influenced by the primary tumor and by the varying dormancy of DTCs, with a special focus on how established metastases persist and grow in distant organs due to feed‐forward loops (FFLs). We discuss in detail the importance of FFL of cancer cells with their microenvironment including the secretome, interaction with specialized tissue‐specific cells, nutrients/metabolites, and that novel therapies should target not only the cancer cells but also the tumor microenvironment, which are thick as thieves. Graphical Abstract Metastases can arise decades after primary breast tumor resection. This review by M. Bentires‐Alj and colleagues describes how the environment of the most common metastatic sites is influenced by the primary tumor and the varying dormancy of disseminated tumor cells, with a focus on feed‐forward loops.
