Description of a Murine Model of Pneumocystis Pneumonia.

Pneumocystis pneumonia is a serious lung infection caused by an original ubiquitous fungus with opportunistic behavior, referred to as Pneumocystis jirovecii. P. jirovecii is the second most common fungal agent among invasive fungal infections after Candida spp. Unfortunately, there is still an inability to culture P. jirovecii in vitro, and so a great impairment to improve knowledge on the pathogenesis of Pneumocystis pneumonia. In this context, animal models have a high value to address complex interplay between Pneumocystis and the components of the host immune system. Here, we propose a protocol for a murine model of Pneumocystis pneumonia. Animals become susceptible to Pneumocystis by acquiring an immunocompromised status induced by iterative administration of steroids within drinking water. Thereafter, the experimental infection is completed by an intranasal challenge with homogenates of mouse lungs containing Pneumocystis murina. The onset of clinical signs occurs within 5weeks following the infectious challenge and immunosuppression can then be withdrawn. At termination, lungs and bronchoalveolar lavage (BAL) fluids from infected mice are analyzed for fungal load (qPCR) and immune response (flow cytometry and biochemical assays). The model is a useful tool in studies focusing on immune responses initiated after the establishment of Pneumocystis pneumonia.

How to promote data sharing among enterprises based on dynamic evolutionary game analysis

ABSTRACT In traditional contexts, enterprises often hesitate to engage in data sharing due to the associated heightened risks and transaction costs. Blockchain technology, leveraging its encryption algorithms and smart contracts, effectively alleviates these challenges, thereby encouraging enterprises to actively participate in data sharing. The adoption of reasonable reward and penalty mechanisms can prevent opportunistic behaviours and stimulate data sharing among businesses. It is noteworthy that blockchain technology and data alliance have a mutually substitutive effect in terms of risk and communication costs, while they complement each other in regulatory and transaction costs. The integration of blockchain technology with data alliance can enhance collaborative revenue and reduce various costs. When distributing collaborative revenue, it is crucial to adhere to the guiding principle of ‘prioritizing efficiency while considering fairness’. Collaboration becomes a reality when all parties collectively achieve a substantial overall revenue threshold. Subsequently, in-depth exploration of fair resource allocation principles is crucial to ensure the equitable distribution of resources.

Social capital and supply chain relationships

AbstractWe examine the role of social capital in influencing decisions pertaining to buyer–supplier relationships. We report that firms make larger relationship‐specific investments when their supply chain partners are headquartered in states with high social capital. This result is more pronounced when supply chain partners have incentives to engage in opportunistic behavior. Furthermore, the duration of supply chain relationships is longer when the firm and its supply chain partner are both headquartered in high social capital states, and when the partner invests in relationship‐specific assets. Collectively, the evidence suggests that social norms reflecting trustworthiness facilitate investment and stability along supply chains.

Do ESG ratings inhibit corporate leverage manipulation? The moderating effects of internal and external supervision

Purpose This paper aims to investigate the relationship between corporate environmental, social and governance (ESG) ratings and leverage manipulation and the moderating effects of internal and external supervision. Design/methodology/approach The authors draw on a sample of Chinese non-financial A-share-listed firms from 2013 to 2020 to explore the effect of ESG ratings on leverage manipulation. Robustness and endogeneity tests confirm the validity of the regression results. Findings ESG ratings inhibit leverage manipulation by improving social reputation, information transparency and financing constraints. This effect is weakened by internal supervision, captured by the ratio of institutional investor ownership, and strengthened by external supervision, captured by the level of marketization. The effect is stronger in non-state-owned firms and firms in non-polluting industries. The governance dimension of ESG exhibits the strongest effect, with comprehensive environmental governance ratings and social governance ratings also suppressing leverage manipulation. Practical implications Firms should strive to cultivate environmental awareness, fulfil their social responsibilities and enhance internal governance, which may help to strengthen the firm’s sustainability orientation, mitigate opportunistic behaviours and ultimately contribute to high-quality firm development. The top managers of firms should exercise self-restraint and take the initiative to reduce leverage manipulation by establishing an appropriate governance structure and sustainable business operation system that incorporate environmental and social governance in addition to general governance. Social implications Policymakers and regulators should formulate unified guidelines with comprehensive criteria to improve the scope and quality of ESG information disclosure and provide specific guidance on ESG practice for firms. Investors should incorporate ESG ratings into their investment decision framework to lower their portfolio risk. Originality/value This study contributes to the literature in four ways. Firstly, to the best of the authors’ knowledge, it is among the first to show that high ESG ratings may mitigate firms’ opportunistic behaviours. Secondly, it identifies the governance factor of leverage manipulation from the perspective of firms’ subjective sustainability orientation. Thirdly, it demonstrates that the relationship between ESG ratings and leverage manipulation varies with the level of internal and external supervision. Finally, it highlights the importance of governance in guaranteeing the other two dimensions’ roles by decomposing overall ESG.

Evaluating tracemaker recovery after the Cretaceous–Paleogene (K–Pg) boundary event: different biotic responses at the Caravaca section

AbstractTrace fossils are an aid to characterize major extinction events, enriching evolutionary paleoecology research. Ichnological analysis at the Cretaceous–Paleogene (K–Pg) marine boundary interval, worldwide, points to a relatively minor disruption in the macrobenthic tracemaker community; that is, trace-fossil assemblages do not change significantly across the K–Pg boundary, showing relatively rapid recovery, locally in just a few years post-impact. To evaluate the incidence of this event and the rapid recovery of the tracemaker community afterwards, the evolution of planktic and benthic groups at the K–Pg boundary interval was analysed in the Caravaca section (Betic Cordillera) based on the integration of available data. In general terms, planktic foraminifera and calcareous nannoplankton dropped in abundance and diversity at the K–Pg boundary, whereas benthic foraminifera did not show significant extinction, but rather a sudden and dramatic decrease in diversity and reorganization. After the K–Pg boundary event, planktic communities exhibit a prolonged delay in recovery—mainly occurring above the dark boundary layer—with respect to benthic foraminifera. The K–Pg boundary event did not induce a severe crisis for the burrowing macroinfauna, as revealed by the similarity between pre- and post-event ichnotaxa, showing a comparatively rapid first colonization phase, less than 2 ky after the event. The record of Zoophycos and Chondrites at the base of the dark boundary layer evidences an opportunistic behaviour of tracemakers and a high independence from oxygen in pore waters and food in the sediment, allowing for the colonization of an overall unfavorable environment.

Adopting restriction: how coalition governments respond to radical right parties

Radical right parties (RRPs) have gained representation in parliaments across Europe, but little is known about their impact on government policy. Even though RRPs tend to end up in opposition, they have considerable influence on policy making within coalition governments. One expectation is that coalition governments are tough on immigration to optimise voter support when being exposed to right-wing parties in parliament. Coalition negotiations temporarily reduce accountability and allow cabinets to adjust policy positions without bearing the costs associated with opportunistic behaviour. This argument is tested using novel data on pre-electoral policy positions and post-electoral immigration policies for coalition cabinets in 24 European democracies from 1980 to 2015. The findings reveal that governments shift to more restrictive immigration policies in face of RRPs. This article expands on prior research on the influence of the radical right by demonstrating its direct influence on coalition governments’ joint immigration policy plans.

ACCOUNTING INFORMATION DISCLOSURE: HOW FAR IS SO FAR

Purpose: Accounting information asymmetry increases moral hazard, agency costs, shareholders’ discontent, and further aggravates the discomfort of minority shareholders. As such, how far is so far when connecting information disclosure with firm characteristics has remained a debate. This study thus investigated the nexus between firm characteristics and accounting information disclosure with emphasis on the banking sub-sector in Nigeria. Theoretical Framework: Accounting information disclosure is not hidden from theoretical discussions within the corridors of opportunistic behaviors, agency-theory and information asymmetry or information failure theory Design/Methodology/Approach: Annual reports of eleven top banks in Nigeria were analyzed covering a period of 5 years from 2010 to 2014 using the firm characteristics – size, profitability, age, and international presence. A disclosure checklist consisting 137 voluntary items was developed and multiple regression analysis performed. Findings: The results revealed a positive significant relationship between accounting information disclosure with age, international exposure, and a negative significant relationship was observed for profitability and size. Generally, the level of disclosure in the banking sector was found to be high at 62%. Research, Practical & Social Implications: This study recommends accounting information democratization and sharing to build and restore confidence in banks’ activities and public perception. Originality/Value: The investigation on how far is so far in accounting information disclosure should be perceived from the eye of the stakeholders investments. Be that as it may, it is only fair and ethically moral for persons/groups that have invested in a business and or in a bank to regularly have access to concrete and verifiable mandatory and voluntary information disclosure on the financial position of their hard-earn funds to make reasonable decisions.

Does corporate governance affect investment efficiency of Indian firms? Panel evidence from new governance indices

AbstractThis study examines the effects of corporate governance (CG) on investment inefficiency for 506 Indian listed firms. Using new stipulations of CG and globally recognized governance practices, an overall corporate governance index (CGI) and five sub‐indices such as board index (BINDEX), audit index (AINDEX), ownership index (OINDEX), nomination and remuneration index (NRINDEX), and disclosure index (DINDEX) were constructed. Employing newly developed governance indices along with firm‐specific control variables, several pooled regression models were estimated. Robustness checks were conducted using two‐step system GMM and an alternate measure of managerial investment efficiency. The pooled estimated coefficient of CGI and sub‐indices (except OINDEX) on investment inefficiency, overinvestment and underinvest is found to be negative and significant suggesting that effective/robust governance at firm level reduces investment inefficiencies (improves investment efficiency) through effective supervision and monitoring thereby reducing the opportunistic behavior of managers.

Body mass mediates spatio-temporal responses of mammals to human frequentation across Italian protected areas.

Protected area (PA) networks are a pivotal tool to fight biodiversity loss, yet they often need to balance the mission of nature conservation with the socio-economic need of giving opportunity for outdoor recreation. Recreation in natural areas is important for human health in an urbanized society, but can prompt behavioural modifications in wild animals. Rarely, however, have these responses being studied across multiple PAs and using standardized methods. We deployed a systematic camera trapping protocol at over 200 sites to sample medium and large mammals in four PAs within the European Natura 2000 network to assess their spatio-temporal responses to human frequentation, proximity to towns, amount of open habitat and topographical variables. By applying multi-species and single-species models for the number of diurnal, crepuscular and nocturnal detections and a multi-species model for nocturnality index, we estimated both species-specific- and meta-community-level effects, finding that increased nocturnality appeared the main strategy that the mammal meta-community used to cope with human disturbance. However, responses in the diurnal, crepuscular and nocturnal site use were mediated by species' body mass, with larger species exhibiting avoidance of humans and smaller species more opportunistic behaviours. Our results show the effectiveness of standardized sampling and provide insights for planning the expansion of PA networks as foreseen by the Kunming-Montreal biodiversity agreement.

Optimizing malaria vector control in the Greater Mekong Subregion: a systematic review and mathematical modelling study to identify desirable intervention characteristics

BackgroundIn the Greater Mekong Subregion (GMS), new vector-control tools are needed to target mosquitoes that bite outside during the daytime and night-time to advance malaria elimination.MethodsWe conducted systematic literature searches to generate a bionomic dataset of the main malaria vectors in the GMS, including human blood index (HBI), parity proportion, sac proportion (proportion with uncontracted ovary sacs, indicating the amount of time until they returned to host seeking after oviposition) and the resting period duration. We then performed global sensitivity analyses to assess the influence of bionomics and intervention characteristics on vectorial capacity.ResultsOur review showed that Anopheles minimus, An. sinensis, An. maculatus and An. sundaicus display opportunistic blood-feeding behaviour, while An. dirus is more anthropophilic. Multivariate regression analysis indicated that environmental, climatic and sampling factors influence the proportion of parous mosquitoes, and resting duration varies seasonally. Sensitivity analysis highlighted HBI and parity proportion as the most influential bionomic parameters, followed by resting duration. Killing before feeding is always a desirable characteristic across all settings in the GMS. Disarming is also a desirable characteristic in settings with a low HBI. Repelling is only an effective strategy in settings with a low HBI and low parity proportion. Killing after feeding is only a desirable characteristic if the HBI and parity proportions in the setting are high.ConclusionsAlthough in general adopting tools that kill before feeding would have the largest community-level effect on reducing outdoor transmission, other modes of action can be effective. Current tools in development which target outdoor biting mosquitoes should be implemented in different settings dependent on their characteristics.Graphical

Exploring Modalities Best Suited for Public Private Partnership Concession Agreements in the Education Sector of Zambia

The Zambian public sector has been known to face several challenges in the provision of infrastructure among others education infrastructure. Thus, the introduction of Public Private Partnerships (PPPs). In as much as the education sector of Zambia can benefit tremendously from the PPP initiative, poorly designed PPP concession agreements risk worsening existing educational sector challenges. The objectives of the paper were to establish the extent of application of PPPs in the Zambian education sector, identify the challenges surrounding concession agreements in PPPs in Zambia, and suggest the right modalities that could be applied to PPP concession agreements in the Zambian education sector. Both secondary and primary data was collected to establish that no private sector entity has had or is currently engaged in an ongoing concession with the Government in the procurement of infrastructure for schools. Challenges surrounding concession agreements in PPPs included contract misspecifications, lack of contractual flexibility, opportunistic behaviour by either party, and shielded concession agreement creation and process. In view of the foregoing, right modalities that could be applied to PPP concession agreements in the Zambian education sector include proper risk allocation, adequate concession period, clear allocation of roles and responsibilities, and inclusion of stabilization clauses.

Integrating agency and resource dependency theories: the moderating effect of board size on the relationship between dividends and firm value in Malaysia

PurposeThis paper aims to examine the moderating effects of board size on the relationship between dividends and firm value in Malaysian settings. The theoretical foundations of this research were the integration between agency and resources dependency theories.Design/methodology/approachPanel data are extracted from DataStream and the annual report for the period of 2012 to 2021, and pooled OLS, random effects, and fixed effects analyses were employed to examine the relationship. Breusch–Pagan Lagrange multiplier (LM) test and the Hausman test used to determine the most appropriate between these three analyses (OLS, random effects, and fixed effects). The results are valid even after calculating the robust standard error to mitigate the potential heteroskedasticity and serial correlation.FindingsThe empirical results show that board size positively moderates the relationship between dividends and firm value in all the models tested. The results indicate that a larger board of size can minimize the agency problem (agency theory) because a larger board size can more effectively monitor and control management's opportunistic behavior due to more set of skilled and talented individuals included in the boardroom (resources dependency theory). Additionally, effective monitoring can also lead to the increase in dividend payout to maintain a good reputation among investors and simultaneously increase firm value.Practical implicationThis study contributes to helping the regulators and industry players in Malaysia to improve existing guidelines for determining dividend and board size to increase firm value. The findings may also provide inputs to the policymakers in recommending the optimum dividend and board size that resulting an increase in valuation.Originality/valueBy incorporating agency and resources dependency theory, authors investigate the moderating effect of board size on dividend and firm value relationships in Malaysian markets.

Social capital and procedural formalism

ABSTRACT Differences in the extent of formalism of civil proceedings between common and civil law countries have expanded between 1950 and 2000. We study the role of social capital in this divergence using data on up to 35 countries. We find that higher-trust societies, and those that are less tolerant of opportunistic behaviours, were more likely to reduce the degree of procedural formalism over time, thus making litigation a more efficient means of seeking administration of justice. This result suggests that lowering of formalism may reflect a cultural bias for less formal dispute resolution among parties in high social capital societies.

Stock Liquidity, Corporate Governance and Dividend Payout: Evidence From Tehran Stock Exchange

The main goal of this article is the impact of Corporate Governance and Stock Liquidity on the Dividend payout. In order to test the hypotheses, a sample of companies accepted in the Tehran Stock Exchange was selected between 2016 and 2021, which was analyzed using R software. The research method is multivariate regression using panel data. According to the research findings, there is not a meaningful relationship between Corporate Governance, Stock Liquidity and Dividend payout. Companies finance through debt regardless of the stock liquidity, therefore, stock liquidity does not have a decisive role in financing. Better corporate governance mechanisms apply more supervision, so that these mechanisms prevent the opportunistic behavior of managers and preventing them from hiding and manipulating information. By testing the mutual effect of stock liquidity and the quality of corporate governance, a significant relationship was found with the dividend payout of companies accepted in the Tehran Stock Exchange. The study tries to contribute to the current literature of corporate governance and stock liquidity by providing new evidence on the causal impacts of stock liquidity and corporate governance quality on dividend payout. Also, this study contributes to the literature on stock liquidity, corporate governance quality and dividend payout by exploring the mechanism of corporate governance quality and dividend payout from equity financing and internal financing.

Shared recycling model for waste electrical and electronic equipment based on the targeted responsibility system in the context of China

The formal recycling of waste electrical and electronic equipment (WEEE) has long faced collection difficulties owing to the inadequate recycling system and insufficient collection capacity under China’s fund-based recycling model. The government has introduced the recycling Target Responsibility System (TRS) to motivate producers to develop and share recycling systems, yet without clear incentive mechanisms. In this study, we provide a “1 + N” shared recycling model referring to the theory of the sharing economy, and we propose a credit mechanism with a deposit system and a penalty mechanism for dishonesty to constrain the opportunistic behavior of sharing. In addition, according to the TRS, we design a “reduction-penalty-subsidy” fund policy to incentivize producers and recyclers to achieve recycling targets. On this basis, we apply evolutionary game theory and system dynamics approach to analyze the collaborative mechanism of shared recycling and the incentive effect of the funding policy. Game analysis yields the evolution of shared recycling from the developing stage to the mature stage. The system simulation results indicate that the government’s “penalty” and “subsidy” strategies provide evident incentives for producers and recyclers, respectively, in the developing stage, whereas endogenous dynamics derived from economies of scale under market mechanisms promote the multi-agent collaborative implementation of shared recycling in the mature stage.

Changing value system, shifting geography of opportunity: Trajectory of migrant workers in the garment industry in Beijing

Research on the geography of metropolitan opportunities has focused on a set of opportunities in different urban areas over time to justify policy interventions. The Beijing government implemented large-scale policy interventions to achieve structural industrial changes in order to stop the downward spiral of poverty and segregation in “urban villages.” Beijing has accelerated the redevelopment of urban villages and helped tens of thousands of low-wage migrant workers in garment villages move to surrounding secondary cities or small towns in Hebei Province with better opportunities. However, low-wage migrant workers did not respond linearly to the intervention. This study analyzes the reasons underlying the response of low-wage migrant workers to these policy interventions. First, the antipoverty policy is a geographic exercise, moving low-end industries from a global center to peripheral locations. This study considers why this mobility strategy for improving opportunity has become the arena for opportunistic behavior and conceptualizes the logic of opportunism and the self-worth of low-wage migrant workers in a metropolitan area. Second, the Beijing government is attempting to disperse the low-end informal industries into formal industrial bases in Hebei. Dispersal campaigns inevitably involve circuitous mobility and the outcome of dispersal is inherently unstable. One of the crucial questions in dispersal strategies is scale. Would an upscaled Beijing-Tianjin-Hebei (BTH) City Region or a downscaled “neighborhood effect” better implement the antipoverty strategy? This dispersal strategy can break up the concentration of migrants, but their perceived opportunities remain in Beijing. One of the obstacles to the full implementation of the dispersal strategy is grassroots opposition. This study uses a three-year survey conducted prior to the COVID−19 lockdown to analyze how displaced migrant workers perceive these opportunities in their processual and networked decision-making. Garment villages are important “anchor places” where migrants can mobilize their social capital and facilitate upward mobility outside a dominant institution in Beijing. This study reveals how garment workers replicated informal habitats in more remote locations in Beijing as the old habitats disappeared.

Public procurement and innovation policy in Russia: a perspective of narrative economics

Objective: to identify narratives describing the use of public procurement system for innovation policy implementation and to critically analyze them.Methods: quantitative analysis of the frequency of narratives, qualitative analysis of narratives to identify protomodels, institutions and social context.Results: in the modern Russian economic system, public procurement is used as a tool for implementing the national innovation policy. The analysis of legal acts regulating public procurement of innovative and high-tech goods showed the trends that potentially reduce the variability of procuring entities' actions and the transparency of procurement procedures. Based on the tools of narrative economics, the authors analyzed the attitude of actors (representatives of the state, business and academia) of the Russian innovation system to the existing practice of public procurement in the context of the national innovation policy. As a result, the work presents a typology of public procurement problems, discussed in mass media, for Russia’s innovative development.Scientific novelty: the considered narratives show that, in relation to the Russian innovation system, the public procurement subjects can act in the logic of the “principal-agent” theory, while the tendency to reduce transparency is welcomed by some actors.Practical significance: institutional analysis of the recent changes in public procurement, including the rules governing the procurement of innovative and high-tech products, has revealed the devolution of formalized rules aimed at the implementation of state innovation policy. Together with the increased level of privacy in organizational activities of procuring entities, this carries the risks of not only increasing the level of opportunistic behavior of the public procurement market subjects, but also decreasing confidence in the entire public procurement system.

Information Infrastructure and Environmental, Social, and Governance Performance of the Enterprise: A Quasi-Experimental Analysis

ABSTRACT Information infrastructure development substantially impacts the transformation of enterprises’ decision-making. Based on the “Information Consumption Demonstration City Construction” policy issued by the Chinese Ministry of Industry and Information Technology in 2016, we conducted a quasi-experiment to examine the effects and mechanisms of information infrastructure construction on the enterprise’s environmental, social, and governance (ESG) performance. Overall, information infrastructure construction was shown to substantially improve the ESG performance of these companies and exhibit a strong promoting effect on labor-intensive and state-owned enterprises. Regarding internal mechanisms, the information infrastructure has accelerated the digital transformation of enterprises and improved information efficiency, which is beneficial for suppressing opportunistic behavior. Regarding external mechanisms, information infrastructure development and ESG investment have jointly reduced corporate financing constraints, improving their credit market performance. These findings provide substantial practical evidence for promoting the construction of an information infrastructure from the perspective of enterprise governance transformation.

Opportunistic leadership behavior and its impact on the spiritual elevation of employees (An analytical study of the opinions of a sample of decision makers in the General Company for Pastry Manufacturing in Baqubah

The current research aims to address the weaknesses in opportunistic leadership behaviors and thus stay away from threatening positions that weaken that leadership, and in a way that is consistent with the spiritual highness of the employees in the company under investigation. Based on the above, the main research problem can be clarified, which is “Is there a statistically significant correlation and impact between... Opportunistic leadership behavior and the spiritual elevation of employees in the researched company. In light of the main research problem, a hypothetical model was built that reflects the relationship and impact between the main research dimensions and variables, and thus finding the best appropriate solutions to that problem. The research relied on the descriptive analytical approach, which gives the possibility of using description in forming a framework. Intellectual and theoretical, the study population was represented by the General Company for Pastry Production in Diyala, where the research community reached 250 individuals representing the decision-makers in the researched company. 80 individuals were selected to represent the research sample from the decision-makers in the researched company. The questionnaire form was distributed in a regular manner to all members of the sample, and all members of the sample were retrieved. The distributed questionnaires enriched the research with important information and data from sources and references related to the theoretical side. As for the field side, reliance was placed on a set of statistical tools, including the questionnaire, the arithmetic mean, and the simple and multiple regression coefficient to stabilize the relationship of correlation and impact. The research reached a set of results and recommendations, the most prominent of which is building successful leadership characteristics from By modifying opportunistic behavior that would eliminate the spiritual highness of workers

Configuration analysis of asymmetric trust between infrastructure PPP project participants

PurposeTrust is the glue that holds cooperative relationships together and often exists in an asymmetric manner. The purpose of this study is to explore how to mitigate the issue of losses or increased transaction costs caused by opportunistic behavior in a soft environment where trust asymmetry is quite common and difficult to avoid.Design/methodology/approachThis study focuses on examining asymmetric trust between the government and the private sector in public-private partnership (PPP) projects. Drawing upon both project realities and relevant literature, the primary conditional variables influencing asymmetric trust are identified. These variables encompass power perception asymmetry, information asymmetry, interaction behavior, risk perception differences and government-side control. Subsequently, through the use of a survey questionnaire, binary-matched data from both the government and the private sector are collected. The study employs fuzzy-set qualitative comparative analysis (fsQCA) to conduct a configurational analysis, aiming to investigate the causal pathways that trigger asymmetric trust.FindingsNo single conditional variable is a necessary condition for the emergence of trust asymmetry. The pathways leading to a high degree of trust asymmetry can be categorized into two types: those dominated by power perception and those involving a combination of multiple factors. Differences in power perception play a crucial role in the occurrence of high trust asymmetry, yet the influence of other conditional variables in triggering trust asymmetry should not be overlooked.Originality/valueThe findings can contribute to advancing the study of trust relationships in the field of Chinese PPP projects. Furthermore, they hold practical value in facilitating the enhancement of trust relationships between the government and the private sector.
