One can know without observation what one is up to, but can one know without observation what someone else is up to? I explore two strategies for defending the claim that one can. The first strategy relies on the fact that one can know what someone is doing by accepting what they tell one about what they are doing. It proposes that testimony can preserve the credentials of a piece of knowledge so that if a benefactor has non-observational knowledge, then a recipient of their testimony can acquire non-observational knowledge by accepting it. The second strategy appeals to the existence of collective activities. It proposes that where a number of people engage in a collective activity, each can know what each is up to, and that knowledge can be had without observation. My goal is to set out both strategies. A secondary aim is to suggest grounds for greater optimism about the prospects of the first strategy than the second. [ABSTRACT FROM AUTHOR]

Purpose: The insidious proliferation of online misinformation represents a significant societal problem. With a wealth of research dedicated to the topic, it is still unclear what determines fake news sharing. This paper comparatively examines fake and accurate news sharing in a novel experimental setting that manipulates news about terrorism. Design/methodology/approach: The authors follow an extended version of the uses-and-gratification framework for news sharing, complemented by variables commonly employed in fake news rebuttal studies. Findings: Logistic regression and classification trees revealed worry about the topic, media literacy, information-seeking and conservatism as significant predictors of willingness to share news online. No significant association was found for general analytical thinking, journalism skepticism, conspiracy ideation, uses-and-gratification motives or pass-time coping strategies. Practical implications: The current results broaden and expand the literature examining beliefs in and sharing of misinformation, highlighting the role of media literacy in protecting the public against the spread of fake news. Originality/value: This is, to the authors' knowledge, the first study to integrate a breadth of theoretically and empirically driven predictors of fake news sharing within a single experimental framework.

Sharing what we know with others has an important role in facilitating people's social learning and communication across settings. To advance the understanding of when and how people share, the present study examined the role of inspiration, an emotion that contains strong motivational elements, on people's sharing tendencies in three studies. Study 1 showed a positive association between the inspiring level of a given message and its likelihood of being shared. Study 2 replicated the finding with carefully controlling for the effect of positivity of a given message. Study 3 further provided evidence that inspiration shaped how people share. The results showed that participants shared inspiring messages in a more innovative way than when they shared less inspiring messages. The present research has implications for how to promote the sharing process in different settings through the role of inspiration. [ABSTRACT FROM AUTHOR]

Sharing experience via social media communication has been examined in psychology, sociology, communication and linguistic studies. While this research has mostly examined consumption experience and health issues, how people make meanings and develop interactions while sharing mundane matters needs more investigation. This paper reports on a pragmatic investigation into individuals sharing their exam experiences in social media groups. Data were collected from two support groups on Douban , a Chinese social networking site that encourages users to share their thoughts, interests and experiences. A total of 400 original posts, 200 each from a group sharing experiences of failure in examinations and a group sharing their success in examinations, were collected and analysed both quantitatively and qualitatively. The findings showed that the two groups were significantly different in the ways they voluntarily disclosed their identities and in the types of expressions they employed to refer to different participants. In addition, they differed significantly in how they sought or offered support in interactions. Similarities and differences between the two groups' sharing are discussed in relation to the instructions of the two groups, their identity construction, the affordances of social media, and the importance of politeness and face in Chinese culture. • This paper reports on a pragmatic investigation into individuals sharing their exam experiences in social media groups. • The failure and the success groups were significantly different in the ways they voluntarily disclosed their identities. • They were also significantly different in the types of expressions used to refer to different participants. • They differed significantly in how they sought or offered support in interactions.

Organizations are increasingly adopting social technology platforms in an effort to support increased knowledge sharing among workers. Although scholarship has indicated that the use of social technologies can increase multiple forms of communication visibility within organizations, little is known about the nature of these relationships and how the benefits of that visibility may differ based on the use of different functionalities of platforms. This study examines how various uses of a social technology platform in a global organization relate to communication visibility and increased metaknowledge among workers. In addition, our analysis investigates how communication visibility relates to workers' knowledge-sharing intentions and engagement. Findings extend theory by indicating that metaknowledge from communication visibility does indeed differ based on whether employees use functionalities that connect communication partners, or interact with communal communication available to third parties.

The present paper offers an approach to the mature thought of Ignacio Ellacuría Beascoechea (1930-1989), focusing on the fundamental categories of historical reality and praxis, and highlighting the importance of integrating different disciplinary perspectives in order to understand reality and overcome ideologization. In this sense, focusing on the relationship between philosophy and theology, it is proposed that Ellacuría resolves the conflict of disciplinary hierarchization and emphasizes the need for a methodological and epistemological balance that allows enriching the concepts and promoting a dialogue with implications in the transformation of society that overcomes the depletion of different knowledges and promotes an ecology of knowledge.

Justice in production is concerned with ensuring the benefits and burdens of work are distributed in a way that is reflective of persons' status as moral equals. While a variety of accounts of productive justice have been offered, insufficient attention has been paid to the distribution of work's benefits and burdens in the future. In this article, after granting for the sake of argument forecasts of widespread future technological unemployment, we consider the implications this has for egalitarian requirements of productive justice. We argue that in relation to all the benefits affiliated with work, other than undertaking social contribution, the technological replacement of work is unproblematic as these benefits could in principle be attained elsewhere. But because social contribution uniquely corresponds to work (when work is understood as more than a paid job), the normative assessment of technological unemployment will turn on the value that theories of justice give to contributive activity. We then argue that despite technological replacement being plainly beneficial insofar as it relieves persons from the burdens of work, such as dangerous work or drudgery, because the nature of care work makes it less susceptible to technological replacement, egalitarian concern will require the burdens of care work to be shared equally between individuals.

Children's sharing behavior is profoundly shaped by social norms within their society, and they can learn these norms by directly observing how most others share in their immediate environment. Here we systematically investigated the impact of majority influence on the sharing behavior of young Chinese children through three studies (N = 336, 168 girls). Four‐ and 6‐year‐olds were allowed to choose 10 favorite stickers and had an opportunity to engage in anonymous sharing. Before making the sharing decision, children were assigned to one of two conditions: watching a video in which three peers all shared 8 out of 10 stickers (i.e., the majority sharing condition) or making their decisions without watching the video (i.e., the control condition). Results showed that both the 4‐ and 6‐year‐old children shared more stickers in the majority sharing condition than in the control condition (Studies 1 & 2). Moreover, the influence of the majority had a stronger effect compared to the influence of a single role model. Children shared more stickers after observing three peers sharing, compared to watching one peer sharing three times (Study 2). Furthermore, children were less likely to copy the majority's non‐sharing behavior when it came to giving away stickers without prosocial outcomes, which was particularly evident among 4‐year‐olds (Study 3). The results reveal that majority influence uniquely shapes children's sharing behavior and that children selectively follow the majority based on whether the behavior exhibits prosocial attributes. A video abstract of this article can be viewed at https://youtu.be/8qNNhf9754I?si=7YfpaFpcD%5fIjlXjJ Research Highlights: Observing a majority of three peers' unanimous generous sharing promoted sharing behavior in both 4‐ and 6‐year‐olds.The influence of three peers on children's sharing was stronger than that of one peer sharing three times.Four‐year‐olds, but not 6‐year‐olds, did not copy the non‐sharing behavior of the majority as it did not lead to prosocial outcomes.

The literature search underpins data collection for all systematic reviews (SRs). The SR reporting guideline PRISMA, and its extensions, aim to facilitate research transparency and reproducibility, and ultimately improve the quality of research, by instructing authors to provide specific research materials and data upon publication of the manuscript. Search strategies are one item of data that are explicitly included in PRISMA and the critical appraisal tool AMSTAR2. Yet some authors use search availability statements implying that the search strategies are available upon request instead of providing strategies up front. We sought out reviews with search availability statements, characterized them, and requested the search strategies from authors via email. Over half of the included reviews cited PRISMA but less than a third included any search strategies. After requesting the strategies via email as instructed, we received replies from 46% of authors, and eventually received at least one search strategy from 36% of authors. Requesting search strategies via email has a low chance of success. Ask and you might receive—but you probably will not. SRs that do not make search strategies available are low quality at best according to AMSTAR2; Journal editors can and should enforce the requirement for authors to include their search strategies alongside their SR manuscripts [ABSTRACT FROM AUTHOR]

Naming or names (ming 名) is one of the key concepts in Daodejing (道德經). According to a popular understanding, names in Daodejing correspond to features (xing 形) of things; ordinary things have names, but Dao is featureless and nameless. What is missing, however, is atheory of the relationship between names and features explaining why ordinary things have names but Dao does not. In this paper, I develop a theory of names in Daodejing that explains how names relate to things and their features. According to this theory, a name corresponds to a feature that is shared by a group of things, and names provide identity conditions for individuating ordinary things. Further, this theory implies that the various descriptions of Dao in Daodejing do not include names; therefore, talking about Dao while insisting that it is unnamable is not committed to any paradox.

Ethnographic research with the Kerewo-speakers in the Kikori area of the Gulf Province shows that they refuse the severance of Australia's and Papua New Guinea (PNG)'s histories. From the Kerewo perspective, PNG's national independence cannot erase valued social relationships forged through past contact with Australia. Drawing on the work of Frederick Cooper and John Pocock, this article contends that Australia's and PNG's shared past should be considered within a single analytical framework that highlights the legacies of colonialism in shaping Papua New Guineans' perceptions of themselves and their place in the world. For Kerewo, recognising a shared past is a necessary (albeit frustrated) basis for re-forging relations in the present. The efforts of historians today to reconnect these stories is political insofar as it seeks to undo the efforts of colonial administrators – in the pursuit of a self-serving decolonisation process – to forget these links.

In this paper, we present an entangled state controlled semi-quantum secret sharing CSQSS protocol for the first time. In this scheme, with the permission of a trusted classical user, B o b 1 , Alice, as a quantum user, can share a one-bit specific message with n classical users, and the secret can only be recovered by the cooperation of all classical users. Then, the protocol is extended where m-bit specific messages, K (k 1 , k 2 ,... , k m) , can be shared with n classical users. The security of the proposed protocol against common attacks is analysed in detail, which shows that the proposed protocol is theoretically secure. Compared with previous SQSS protocols, the proposed protocol can achieve a lower cost because it does not use returning qubits for producing the secret message, uses fewer returning qubits for eavesdropping check, and does not perform entangled state measurement. Moreover, the proposed protocol has the highest qubit efficiency among the previous SQSS schemes. [ABSTRACT FROM AUTHOR]

While affective disposition theory (ADT) claims that moral judgment of a character is the key mechanism underlying enjoyment, we often enjoy stories where characters violate our moral standards (morally ambiguous characters, or MACs). Initial research suggests that similarity between MACs and viewers (e.g. sharing ethnicity) may increase moral approval. However, the effect of internal similarity (similarity in higher-order human qualities) on moral judgment of MACs is underexplored. Humans share three basic psychological needs but are motivated by these needs to different degrees. Thus, similarity in degree of sensitivity to a given need is an internal quality that participants can share with MACs. The effect of similarity in basic needs on moral judgment of MACs is examined in a posttest-only experiment with 185 participants. Similarity in basic needs had a small effect on moral judgment of MACs as people, although it had no effect on judgment of a MAC's behavior. [ABSTRACT FROM AUTHOR]

Multi-Task Learning is an effective method for learning cross-task knowledge. However, existing methods cannot fairly treat each task, their public parts are prone to continuously fit new tasks and decrease the performances of previous tasks. In this paper, we propose the Fitting-sharing Multi-Task Learning method to address this problem. In the Fitting step, a group of indicator parameters are trained to extract task-specific features and store them into an in-task template matrix. After all models converge, the indicators and templates are frozen to protect the learned knowledge. In the Sharing step, a group of connector parameters are trained to acquire information from other templates and to reason cross-task knowledge. Since the learning and sharing processes are separate, each model can acquire the learned knowledge from other tasks without affect them, and the imbalanced cross-task knowledge problem can be naturally avoided. Experimental results on public datasets illustrate that the proposed method can insistently improve the performance compared with existing methods. [ABSTRACT FROM AUTHOR]

Real-time collaborative programming (RCP) entails developers working simultaneously, regardless of their geographic locations. RCP differs from traditional asynchronous online programming methods, such as Git or SVN, where developers work independently and update the codebase at separate times. Although various real-time code collaboration tools (e.g., Visual Studio Live Share, Code with Me, and Replit) have kept emerging in recent years, none of the existing studies explicitly focus on a deep understanding of the processes or experiences associated with RCP. To this end, we combine interviews and an e-mail survey with the users of Visual Studio Live Share, aiming to understand (i) the scenarios, (ii) the requirements, and (iii) the challenges when developers participate in RCP. We find that developers participate in RCP in 18 different scenarios belonging to six categories, e.g., pair programming, group debugging, and code review. However, existing users' attitudes toward the usefulness of the current RCP tools in these scenarios were significantly more negative than the expectations of potential users. As for the requirements, the most critical category is live editing, followed by the need for sharing terminals to enable hosts and guests to run commands and see the results, as well as focusing and following, which involves "following" the host's edit location and "focusing" the guests' attention on the host with a notification. Under these categories, we identify 17 requirements, but most of them are not well supported by current tools. In terms of challenges, we identify 19 challenges belonging to seven categories. The most severe category of challenges is lagging followed by permissions and conflicts. The above findings indicate that the current RCP tools and even collaborative environment need to be improved greatly and urgently. Based on these findings, we discuss the recommendations for different stakeholders, including practitioners, tool designers, and researchers. [ABSTRACT FROM AUTHOR]

A queueing system with the discipline of flexible limited sharing of the server is considered. This discipline assumes the admission, for a simultaneous service, of only a finite number of orders, as well as the use of a reduced service rate when the bandwidth required by the admitted orders is less than the total bandwidth of the server. The orders arrive following a batch-marked Markov arrival process, which is a generalization of the well-known MAP (Markov arrival process) to the cases of heterogeneous orders and batch arrivals. The orders of different types have different preemptive priorities. The possibility of an increase or a decrease in order priority during the service is suggested to be an effective mechanism to prevent long processing orders from being pushed out of service by justarrived higher-priority orders. Under a fixed priority scheme and a mechanism of dynamic change of the priorities, the stationary analysis of this queueing system is implemented by considering a suitable multidimensional continuous-time Markov chain with a generator that has an upper Hessenberg structure. The possibility of the optimal restriction on the number of simultaneously serviced orders is numerically demonstrated. [ABSTRACT FROM AUTHOR]

Urban sprawl does not invariably impede factor agglomeration; rather, it can foster polycentric urban configurations, thereby enhancing productivity and encouraging enterprise innovation. This study investigates the effect of urban sprawl on enterprise innovation using data for A-share listed Chinese companies from 2010 to 2020. The results reveal a significant inverted U-shaped relationship between urban sprawl and enterprise innovation, particularly among large enterprises, well-established entities, non-state-owned enterprises, and those operating in non-manufacturing sectors. Additionally, the effects of urban sprawl on the inverted U-shaped relationship are more pronounced in the north-eastern regions and small cities. Regional integration significantly moderates the inverted U-shaped relationship between urban sprawl and enterprise innovation. This research contributes new insights to the field of enterprise innovation, offering theoretical and empirical support for analyzing the economic implications of urban sprawl.

We explore if misinformation from political elites (i.e., members of the US Congress) and extreme partisan information from media outlets generate greater engagement than accurate information and non‐extreme partisan information. We also investigate how exposure to these information types leads to negative emotions (e.g., anger) in individuals and its association with attitude polarisation. To this end, we analysed fact‐checked tweets from political elites, tweets from media outlets and replies to those tweets. Together, these tweets received more than 100 000 replies and were shared more than two million times. We also conducted two online experiments. Our field studies reveal that misinformation and extreme partisan information are associated with higher levels of negative emotions and greater engagement than accurate information and non‐extreme partisan information. Our data also show that—while negative emotions in response to extreme partisan information are higher among social media users at the ideological extreme than those at the ideological centre—there is no difference in the two groups' level of negative emotions in response to misinformation. The online experiments demonstrate that exposure to misinformation and extreme partisan information elicits stronger negative emotions than exposure to accurate information and non‐extreme partisan information. These negative emotions, in turn, contribute to attitude polarisation. Our work makes practical and theoretical contributions concerning social media information sharing, negativity and political polarisation. We also provide future research avenues with associated research questions. [ABSTRACT FROM AUTHOR]

Knowledge sharing, although a key process for achieving business success and competitive advantage, does not always run smoothly. A number of factors, also called knowledge sharing barriers, hinder this process. They are extremely diverse and sometimes hard to find. The manifestation of knowledge sharing barriers is highly dependent on the context and in each organisation they manifest in a different way depending on the individual characteristics of the employees, the organisational structure and culture, the relevance and adequacy of the information and communication technologies used, etc. They cannot be completely overcome or eliminated, but their negative impact on knowledge sharing can be mitigated or minimised. The aim of the present study is to identify and rank knowledge sharing barriers in Bulgarian companies based on a literature review and conducting an empirical study. The research revealed three main barriers to knowledge sharing – lack of time, inadequate organisational culture and lack of trust. At the same time, some of the most frequently discussed barriers to knowledge sharing in the literature were not highly rated by respondents. The results of the research can serve business management as a guide in building a knowledge management system and an environment in which people will be able to freely share their knowledge.

Joint attention is an early-emerging and uniquely human capacity that lies at the foundation of many other capacities of humans, such as language and the understanding of other minds. In this article, I summarize what developmentalists and philosophers have come to find out about joint attention, and I end by stating that two problems or questions of joint attention require additional research: 1) the relation between joint attention and the skills for dyadic sharing or affect exchange in young infants, and 2) the evolution of joint attention.

While there is much research on coordinating the dual‐channel supply chain using the revenue‐sharing contract, it is unclear if there is a better mechanism design in the buy‐online‐and‐pickup‐in‐store (BOPS) mode. In this channel integration environment, the customer service provided by the bricks‐and‐mortar store is critical to the chain's success. Based on a stackable game model, we analyze the contract methods for the cases of revenue sharing and no revenue sharing, where the latter is classified into two types: All the credit goes to the offline or online channel. Focusing on improving consumer service and supply chain performance in the BOPS mode, we observe that revenue sharing is not necessarily the best contract type, while the non‐revenue‐sharing contract of a lump‐sum subsidy plus quantity discount can coordinate the supply chain. We also analyze the impacts of some endogenous parameters and derive the conditions for the equilibrium outcomes. We find that revenue sharing cannot effectively stimulate the offline channel to improve its service effort as the offline channel is more concerned about service cost sharing than revenue sharing. The results are similar to those of revenue allocation to the online or offline channel in the BOPS mode, but the conditions are slightly different. Conducting numerical studies to gain insights from the analytical findings, we find that the subsidy contract is better than the revenue‐sharing approach under various market conditions.

[Purpose] Spectrum is a scarce and valuable national resource. With 5G, it is predicted that the demand for spectrum will increase gradually. In order to overcome the increasing data traffic problem and connection needs, the spectrum should be used as efficiently as possible. This paper aims to develop a new perspective on spectrum management in Turkey, and the applicability of spectrum sharing applications in Turkey has been investigated. Suggestions were made regarding the changes that can be made in the current legislation. [Methodology/Approach/Design] Within this study, interviews were held with the three leading mobile operators in Turkey through focus group discussion, and evaluations were made about the approach of Turkey's mobile communication sector to the subject. In addition, innovative spectrum management practices in Europe and United States (US) regarding the emerging spectrum sharing approach were examined. The current practices of European countries were presented in the semi-structured interview via e-mail. [Findings] This paper provides opinions of Turkish leading mobile operators about spectrum sharing, current EU and US practices, and necessary changes in Turkish legislation to enable spectrum sharing. A new perspective on spectrum management in Turkey has been developed, and the applicability of spectrum sharing applications in Turkey has been investigated. Suggestions were made regarding the changes that can be made in the current legislation. [Practical Implications] What outcomes and implications for practice, applications and consequences are identified? How will the article impact on society, business, or enterprise? What changes to practice should be made as a result of this research? What is the legal or economic impact? [Originality/Value] This paper fulfills the need for originality and presents new knowledge about spectrum sharing in Turkey's telecommunication sector. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to explore the relationship between higher educational institution bullying policies and the subsequent cultural impact to determine the effectiveness of policy in ameliorating bullying within the university culture. Design/methodology/approach: This study consisted of two separate but related case studies at two universities in different countries, focussing on university staff. The field work gathered data about existing anti-bullying policy, the extent to which it was part of the organisational culture for staff, and the levels of staff bullying experienced or seen within the organisation. Both qualitative and quantitative data were collected. Findings: The study found that despite one university having significant policy and the other having very little policy, the knowledge of policy in both universities was and subsequent experience of bullying for staff were very similar. Research limitations/implications: The findings indicate that anti-bullying policy alone appears to have a limited impact on organisational behaviour. This suggests that the entrenched and historical master/servant relations of academia enable such practices to continue. Policy implementation is insufficient and training and development to generate more inclusive, people-focussed management cultures is necessary to ameliorate bullying behaviour. Practical implications: The paper draws on the experiences, critique and suggestions of the study participants to prepare a possible agenda for cultural change that human resource (HR) managers could develop in association with academic and professional managers within their institution. Social implications: The findings suggest that in any social setting or organisational structure where strong historical patterns of master/servant endure, the opportunity for bullying behaviours to grow and flourish is fertile and that policy statements alone may have little impact on curtailing such behaviour. Originality/value: This study makes two contributions to existing knowledge. First, it provides evidence that anti-bullying policy is alone unlikely to have an effective impact on instances of bullying within the culture. Second, the case study contrast displays that unacceptable levels of bullying exist in two very different institutions in two very different cultures. Whilst one country has a war-torn history and the other exists in splendid isolation, the same patterns persist, indicating that universities have structured cultural issues that are difficult to change.

Across three studies, this research elucidates how message frames—sharing versus donating—can affect consumers' private information disclosure for societal benefits through perceived sacrifice. This effect is moderated by perceived importance of the cause. First, we demonstrate that the sharing (donating) frame can generate more (less) private information disclosure for societal benefits. Second, we examine the mechanism by which the sharing (donating) frame leads to less (more) perceived sacrifice and then more (less) information disclosure. Third, we introduce the perceived importance of the cause and find that for people who perceive the importance of the cause is high, the donating (sharing) frame leads to less (more) perceived sacrifice and stronger (weaker) intention for private information disclosure. This research has implications for marketers, consumers, and society as a whole. [ABSTRACT FROM AUTHOR]

This study aims to create and validate a scale that measures peer collaboration among secondary school students. The study had three objectives: 1) to identify the constructs of collaboration, 2) to develop a collaboration scale, and 3) to validate the collaboration scale. The study included 363 9th-grade students, and after an extensive literature review, it identified four constructs of collaboration: social interdependence, conflict resolution, cooperation, and sharing of resources. The consistency between these constructs was found to be positive. The scale reliability was established with a Cronbach's alpha coefficient of 0.768 and a test-retest reliability coefficient of 0.71. The content validity of the scale was also established with a Cohen kappa coefficient of 0.66. The study found that differences between boys and girls can be determined by obtaining standard scores on the collaboration scale. This new collaboration scale will be a useful tool for practitioners who use constructivist pedagogy to measure collaboration. [ABSTRACT FROM AUTHOR]

Image Secret Sharing (ISS) is a cryptographic technique used to distribute secret images among multiple users. However, current Visual Secret Sharing (VSS) schemes produce a halftone image with only 50% contrast when reconstructing the original image. To overcome this limitation, the Randomized Image Secret Sharing (RISS) scheme was introduced. RISS achieves a higher contrast of 70% when extracting the secret image but comes with a high computational cost. This research paper presents a novel approach called Graphics Processing Unit (GPU)-based Randomized Image Secret Sharing (GRISS), which utilizes data parallelism within the RISS pipeline. The proposed technique also incorporates an Autoencoder-based Single Image Super-Resolution (ASISR) to enhance the contrast of the recovered image. The performance of GRISS is evaluated against RISS, and the contrast of the ASISR images is compared to current benchmark models. The results demonstrate that GRISS outperforms state-of-the-art models in both efficiency and effectiveness. [ABSTRACT FROM AUTHOR]

Based on social capital theory, this paper aims to investigate the impact of member enterprises of alien merchant chambers on enterprise innovation, within A‐share listed companies on the Shanghai and Shenzhen Stock Exchanges of China from 2010 to 2020. Additionally, the study seeks to explore the role played by social capital resulting from participation in these alien merchant chambers. Furthermore, we delve into the moderating effects of the number of alien merchant chambers and the degree of marketization in the enterprise's location. Moreover, we analyze the influence of heterogeneity in firm ownership and firm type. Our findings reveal that member enterprises of alien merchant chambers can increase their social capital and consequently promoting innovation; both the quantity of alien merchant chambers and the level of marketization in an enterprise's location positively influence this enhancement. Furthermore, the impact of state‐owned enterprises and non‐high‐tech enterprises on enterprise innovation, following their engagement with alien merchant chambers, surpasses that of non‐state‐owned enterprises and high‐tech enterprises. This research bridges the gap in understanding the corporate governance implications of alien merchant chambers, provides empirical evidence concerning Chinese alien merchant chambers, and addresses inquiries regarding the influence of merchant chambers' social capital. Additionally, it proposes a novel approach for listed companies to overcome resource constraints and to collaboratively pursue development, especially in light of the challenges posed by the COVID‐19 pandemic.

The Internet of Things (IoT) includes billions of sensors and actuators (which we refer to as IoT devices) that harvest data from the physical world and send it via the Internet to IoT applications to provide smart IoT services and products. Deploying, managing, and maintaining IoT devices for the exclusive use of an individual IoT application is inefficient and involves significant costs and effort that often outweigh the benefits. On the other hand, enabling large numbers of IoT applications to share available third-party IoT devices, which are deployed and maintained independently by a variety of IoT device providers, reduces IoT application development costs, time, and effort. To achieve a positive cost/benefit ratio, there is a need to support the sharing of third-party IoT devices globally by providing effective IoT device discovery, use, and pay between IoT applications and third-party IoT devices. A solution for global IoT device sharing must be the following: (1) scalable to support a vast number of third-party IoT devices, (2) interoperable to deal with the heterogeneity of IoT devices and their data, and (3) IoT-owned, i.e., not owned by a specific individual or organization. This paper surveys existing techniques that support discovering, using, and paying for third-party IoT devices. To ensure that this survey is comprehensive, this paper presents our methodology, which is inspired by Systematic Literature Network Analysis (SLNA), combining the Systematic Literature Review (SLR) methodology with Citation Network Analysis (CNA). Finally, this paper outlines the research gaps and directions for novel research to realize global IoT device sharing. [ABSTRACT FROM AUTHOR]

Background: Cannabis use before the COVID-19 pandemic for many involved sharing prepared cannabis for inhalation, practices that were less prevalent during the pandemic. State-level COVID-19 containment policies may have influenced this decrease. This study examined the extent to which the intensity of state-level COVID-19 policies were associated with individual-level cannabis sharing. Findings have the potential to guide harm reduction policies for future respiratory pandemics and seasonal respiratory virus waves. Methods: This study used cross-sectional individual-level data from the COVID-19 Cannabis Study, an anonymous U.S.-based web survey on cannabis use disseminated during the early phase of the pandemic (Full sample N = 1,883). We combined individual-level data with state-level policy data from Kaiser Family Foundation's State COVID-19 Data and Policy Actions for three time-points from June to August 2020 that overlapped with the survey period. Cannabis sharing was dichotomized as any versus no sharing. We adapted a previously published coding framework to score the intensity of COVID-19 policies implemented in each U.S. state and averaged the policy score across the time period. We then used Poisson regression models to quantify the associations of the average state-level COVID-19 policy score with cannabis sharing during the pandemic. Results: Participants (n = 925) reporting using inhalation as a mode for cannabis use were included in this analysis. Most respondents were male (64.1%), non-Hispanic White (54.3%), with a mean age of 33.7 years (SD 8.8). A large proportion (74.9%) reported sharing cannabis during the pandemic. Those who shared cannabis more commonly lived in states with a lower average policy score (16.7, IQR 12.3–21.5) compared to those who did not share (18.6, IQR 15.3–25.3). In adjusted models, the prevalence ratio of any cannabis sharing per every 5-unit increase in the average COVID-19 policy score was 0.97 (95% CI 0.93, 1.01). Conclusions: Fewer individuals shared cannabis in states with more intense COVID-19 containment policies compared to those in states with less intense policies. Individuals who use cannabis may be willing to make changes to their behavior and may further benefit from specific and directed public health messaging to avoid sharing during respiratory infection outbreaks.

Conventional techniques for sharing paper documents in teleconferencing tend to introduce two inconsistencies: 1) media inconsistency: a paper document is converted into a digital image on the remote site; 2) space inconsistency: a workspace deliberately inverts the partner's handwriting to make a document easy to read. In this paper, we present a novel system that eliminates these inconsistencies. The media and space inconsistencies are resolved by reproducing a real paper document on a remote site and allowing a user to handover the paper document to a remote partner across a videoconferencing display. From a series of experiments, we found that reproducing a real paper document contributes to a higher sense of information sharing. We also found that handing over a document enhances a sense of space sharing, regardless of whether the document is digital or paper-based. These findings provide insights into designing systems for sharing paper documents across distances. [ABSTRACT FROM AUTHOR]

Motivation The scale of omics research presents many obstacles to full sharing and access to analysis results. Current publication models impose limits on the number of pages and figures, requiring careful preparation and selection of content. At the same time, depositing data in open repositories significantly shifts the burden of access and reproduction to readers, who may include people who are not programmers or analysts. Results We introduce shinyExprPortal, an R package that implements omics web portals with minimal coding effort.

Cloud-based Radio Access Network (Cloud-RAN) leverages virtualization to enable the coexistence of multiple virtual Base Band Units (vBBUs) with collocated workloads on a single edge computer, aiming for economic and operational efficiency. However, this coexistence can cause performance degradation in vBBUs due to resource contention. In this paper, we conduct an empirical analysis of vBBU performance on a Linux RT-Kernel, highlighting the impact of resource sharing with user-space tasks and Kernel threads. Furthermore, we evaluate CPU management strategies such as CPU affinity and CPU isolation as potential solutions to these performance challenges. Our results highlight that the implementation of CPU affinity can significantly reduce throughput variability by up to 40%, decrease vBBU's NACK ratios, and reduce vBBU scheduling latency within the Linux RT-Kernel. Collectively, these findings underscore the potential of CPU management strategies to enhance vBBU performance in Cloud-RAN environments, enabling more efficient and stable network operations. The paper concludes with a discussion on the efficient realization of Cloud-RAN, elucidating the benefits of implementing proposed CPU affinity allocations. The demonstrated enhancements, including reduced scheduling latency and improved end-to-end throughput, affirm the practicality and efficacy of the proposed strategies for optimizing Cloud-RAN deployments.

This study investigated whether the interference between two tasks in dual-task processing stems from bottleneck limitations or insufficient cognitive resources due to resource sharing. Experiment 1 used tone discrimination as Task 1 and word or pseudoword classification as Task 2 to evaluate the effect of automatic versus controlled processing on dual-task interference under different SOA conditions. Experiment 2 reversed the task order. The results showed that dual-task interference persisted regardless of task type or order. Neither experiment found evidence that automatic tasks could eliminate interference. This suggests that resource limitations, rather than bottlenecks, may better explain dual-task costs. Specifically, when tasks compete for limited resources, the processing efficiency of both tasks is significantly reduced. Future research should explore how cognitive resources are dynamically allocated between tasks to better account for dual-task interference effects. [ABSTRACT FROM AUTHOR]

This article revisits claims made a decade ago about the importance of the word "sharing" in the context of social network sites (SNSs). Based on an analysis of the home pages of 61 SNSs between the years 2011 and 2020, the findings incontrovertibly show that "sharing" has lost its central place in the terminology employed by social media platforms in their self-presentation. Where in the mid-2000s SNSs relied heavily on a rhetoric of sharing to promote their services, by 2020, this rhetoric had been almost entirely dropped. The research reported here implies that social media platforms no longer feel a need or desire to be associated with these cultural beliefs. Given this, questions are raised as to whether "sharing" remains a keyword for social media. [ABSTRACT FROM AUTHOR]

Ruling elites commonly concede institutional reforms such as expanding the franchise. In existing models, sharing power in this manner enables ruling elites to credibly commit to perpetual redistribution. In 'Power Sharing with Weak Institutions,' Powell (2024) explains why the commitment problem runs deeper: When institutions are weak, elites are likely to block the implementation of promised institutional concessions. I provide new insights into three foundational premises of Powell (2024) and related models. First, I identify a necessary condition for a common result: Ruling elites always minimize permanent power-sharing concessions vis-à-vis temporary concessions, subject to preventing revolt. However, unless reforming institutions is somehow costly, these two tools are perfect substitutes. Second, I discuss how to conceptualize institutional strength within this class of models. Third, in weak institutional environments, I suggest how scholars can model credible commitments to share power or democratize. [ABSTRACT FROM AUTHOR]

Democratic transitions, franchise extensions, and civil war settlements can often be seen as power-sharing agreements in which opposing factions try to use institutional structures to 'lock in' the terms of a settlement. But the commitment power inherent in institutions varies. When the institutional environment is weak and credibility is low, it is difficult for a powerful elite to tie its hands and give up power. This article studies a window-of-opportunity model in which an enfranchised elite faces a periodic threat. Institutional weakness is parameterized in terms of the elite's marginal return to trying to undermine a power-sharing agreement. The analysis shows that (i) bargaining breaks down if the overall institutional environment is too weak and why it does; (ii) equilibrium agreements share more power with the opposition when the institutional environment is weak; (iii) there is a non-monotonic relation between power sharing and how often the opposition poses a threat; and (iv) power sharing is path dependent.

In this article, we study the fluctuations of the empirical occupa)tion measures of servers around their mean-field limit in a large system of heterogeneous processor sharing servers. It is assumed that there are M different servers grouped by their speeds and that the total number of servers is N. In particular, we study the sensitivity of the fluctuations to arrival rate parameters at the diffusion scale. The job arrival process is assumed to be Poisson with rate N(λ − β/√N ) and the job lengths are assumed to be exponentially distributed with unit mean. On arrival, a finite number of servers from each group are selected and the destination server depends on the server occupancy normalized to their speeds and pre-defined thresholds, referred to as the Join-Below-Threshold scheme. We derive Functional Central Limit Theorems (FCLTs) for the fluctuations that enable us to estimate the error of the mean field approximations to the empirical measures associated with a system with N servers. We then use these results to show mean response time for finite systems can be approximated by the response time given by the mean-field limit and the error isO( 1/√N ) for which the constants can be precisely calculated.

The EU and its member states have provided an unprecedented amount of military, humanitarian and financial aid to Ukraine after Russia's attack on February 24, 2022. However, while some EU member states have provided a disproportionately high level of support to Ukraine, other member states committed an unexpectedly low level of aid. This article aims to explain the diverging levels of EU member state support to Ukraine by building on theories of military burden-sharing. Methodologically, it applies the innovative fit robustness procedure of Coincidence Analysis (CNA). The results of the analysis indicate that conditions derived from theories of military burden-sharing can explain support to Ukraine. More specifically, the pattern of support was (mainly) explained by the level of threat that each member state faced from Russia, past military investments and public opinion. Conversely, in contrast to the frequently tested and confirmed exploitation hypothesis, the economic size of the member states did not have an impact on their support to Ukraine.

As climate change impacts and competition for water increases, sharing of water resources is becoming a challenging endeavour. This becomes harder in a transboundary setting where a basin is shared by different countries in a region that is 60% arid and semi-arid areas, such as the Horn of Africa where tensions due to water scarcity are high. Stakeholders in the transboundary settings often represent varied interests, drawn from different sectors and levels from local to national to regional scales in the riparian countries. Hence the need for a benefit-sharing dialogue. [ABSTRACT FROM AUTHOR]

Debates on allies' contributions to alliances focus mainly on the material dimension. Accordingly, smaller partners are often belittled for failing to contribute their fair share to their defensive alliances with more powerful allies. While acknowledging that junior partners' contributions do not match the same level of material capabilities provided by a more significant power like the United States, this study highlights the importance of other intangible contributions. We argue that defensive alliances during peacetime require a crucial, albeit overlooked, ideational contribution by all allies. We examine the US–Japan and ANZUS alliances to explore the process through which junior partners advance the interests of an alliance through ideational contributions. Our findings reveal that Japan and Australia contribute to their respective alliances with the United States by mobilizing fundamental ideas and norms that sustain and promote a specific global order and security vision. We maintain that such intangible contributions are necessary for alliance success. [ABSTRACT FROM AUTHOR]

This article investigates how a district administration in Bangladesh managed COVID‐19 pandemic risk governance. Interviews were conducted with civil administrators, local government representatives, and representatives from community‐based organizations and nongovernmental organizations. The findings indicate that, despite limited health facilities, widespread ignorance of the virus, joblessness among wage earners, economic pressure, and a massive outbreak of COVID‐19, the district administration has demonstrated its diligence, professionalism, local knowledge, and promptness in providing optimal public services through coordination and information sharing among all stakeholders. The synergies and coordination between local administration, security forces, and local government representatives were great challenges in implementing nonpharmaceutical polices and support programs.

Ridesharing effectively tackles urban mobility challenges by providing a service comparable to private vehicles while minimising resource usage. Our research primarily concentrates on dynamic ridesharing, which conventionally involves connecting drivers with passengers in need of transportation. The process of one-to-one matching presents a complex challenge, particularly when addressing it on a large scale, as the substantial number of potential matches make the attainment of a global optimum a challenging endeavour. This paper aims to address the absence of an optimal approach for dynamic ridesharing by refraining from the conventional heuristic-based methods commonly used to achieve timely solutions in large-scale ride-matching. Instead, we propose a novel approach that provides snapshot-optimal solutions for various forms of one-to-one matching while ensuring they are generated within an acceptable timeframe for service providers. Additionally, we introduce and solve a new variant in which the system itself provides the vehicles. The efficacy of our methodology is substantiated through experiments carried out with real-world data extracted from the openly available New York City taxicab dataset. [ABSTRACT FROM AUTHOR]

Digital platforms facilitate the coordination, match making, and value creation for large groups of individuals. In consumer-to-consumer (C2C) online sharing platforms specifically, trust between these individuals is a central concept in determining which individuals will eventually engage in a transaction. The majority of today's online platforms draw on various types of cues for group coordination and trust building among users. Current research widely accepts the capacity of such cues but largely ignores their changing effectiveness over the course of a user's lifetime on the platform. To address this gap, we conduct a laboratory experiment, studying the interplay of cognitive and affective trust cues over the course a multi-period trust experiment for the coordination of groups. We find that the trust-building capacity of affective trust cues is time-dependent and follows an inverted u-shape form, suggesting a dynamic complementarity of cognitive and affective trust cues.

Existence of nonlinear loads makes load power sharing more challenging in the islanded microgrids. Conventional droop control may cause the poor harmonic power sharing among the distributed generations (DGs) due to the mismatched line impedance. This paper proposes an adaptive regulation method of the virtual harmonic impedance for the accurate harmonic power sharing. Consensus algorithm is used to regulate adaptively the virtual harmonic impedance according to the harmonic power sharing error among the DGs with considering of the mismatched line impedance. This method does not require the prior knowledge of the line impedance. The feasibility of the proposed method is demonstrated by simulation result for achieving the accurate harmonic power sharing to reduce the voltage distortion at the point of common coupling (PCC).

Faced with the environmental emergency, eco-design needs to be "augmented" in order to further reduce the environmental impact of the products we use. To avoid products that are overloaded with unnecessary functions or that do not fully meet the consumer's needs, products whose lifespan is too short in relation to the resources consumed for their production, or products that are never fully used because they meet needs that are too infrequent, this article argues that we should consider a different frame of reference than lifecycle thinking, based on the maximum usefulness of exploitation of the extracted raw materials. This new framework called "Usefulness Thinking" focuses on the usefulness of the consumed resources in relation to 1/ the usage needs of consumers, 2/ the product exploitation time and 3/ its exploitation space/community. Following an analysis of the literature, the article presents the initial methodological drivers for an eco-design approach based on "Usefulness thinking" and applies it to the case of a cordless upright vacuum cleaner for a consumer living in an apartment or a detached house. For each configuration, a significant environmental performance is obtained, approaching a gain factor of 2. [ABSTRACT FROM AUTHOR]
