Effect of corporate governance board leadership models and attributes on earnings quality of quoted nigerian companies

Abstract Purpose This study examined the effect of corporate governance leadership models and attributes on firms’ earnings quality using evidence from Nigerian quoted firms. Design/Methodology/Approach This study used an ex-post facto design with a two-stage multiple random and fixed effect regression analyses. A sample of 37 quoted firms in Nigerian Stock Exchange between 2014 and 2018 was selected for the study. Findings Relative to unitary corporate leadership, dual board leadership model outperformed and significantly improves earnings persistence and value relevance. Earnings persistence and value relevance increased in boards where CEOs and board chairpersons have equal financial expertise. Also the quality of earnings improved significantly with a good mix of financial expertise and legal skills in the board. Thus, the capital market places a premium on such good leadership attribute mix. Research Limitation This study concentrated on non-financial firms in Nigeria. Thus, it should not primarily be generalized as it is context-specific and most applicable among the developing economies Policy Implication The implication is that investors can mitigate adverse portfolio selection if they target firms, where both CEOs and board chairpersons have strong accounting and legal knowledge mix. Investors should consider board leadership structures in assessing the overall firms’ earnings quality. Leadership roles separation provides for higher reporting quality. Originality This study provides the latest evidence of the effect of board leadership models and attributes on firms’ earnings quality in Nigeria. It makes original contribution to the effect of corporate governance on earnings persistence and predictability and how the market reacts to certain attribute combinations.
Users' Involvement in Value Co‐Creation: The More the Better?

Literature on value co-creation often postulates that a greater degree of co-production increases the potential of value co-creation. To test this hypothesis , we build a computational model of value proposition inspired by March's model of organizational learning (1991[24]). The model allows to represent various cases of co-creation: (i) without co-production, (ii) with downstream co-production, and (iii) with upstream co-production. Repeated simulations are partly supporting the literature. On one hand, we find that deeper involvement of consumers into the value offering process increases the potential for value co-creation. One the other hand, we find that co-production can increase inequalities of satisfaction among consumers. Also, while scenarios with learning consumers offer the highest potential for value co-creation, a negative relationship emerges between the number of learning consumers and organizational performance. We thank the two anonymous reviewers for their very insightful comments on an earlier version of this paper. This paper draws on a research carried out within the Co-Val project, funded by the European Commission under the Horizon 2020 framework.
The trend of the Gini coefficient of China (1978–2010)

ABSTRACT This study proposes a new approach to analyse the effects of an overlap term on the calculation of the overall Gini coefficient and estimates China’s Gini ratios since the adoption of the economic reform and open-door policies. A decomposition of the Chinese Gini coefficient for 1978–2010 reveals that the key factor contributing to income inequalities is the income disparity between rural and urban inhabitants. We further investigate the features of this income inequality between rural and urban areas and employ statistical approaches to evaluate the effects of urbanisation and rural-to-urban average income on nationwide income inequality. The results show that accelerating the pace of urbanisation is mainly responsible for decreasing China’s income disparity. Drawing on these results, we conclude with suggestions for related policies.
Visualizing Climate Change Adaptation: An Effective Tool for Agricultural Outreach?

Landscape photovisualizations (PVZs) are digitally altered photographs that show existing landscapes altered to include a simulated future scenario. They are commonly used to support dialogue and decision-making in multistakeholder contexts. In agricultural sectors, stakeholders increasingly must contend with pressures to adapt to climatic changes and shifts in weather patterns. This study examines the potential of PVZs to engage agricultural stakeholders about climate change adaptation, specifically around best management practices (BMPs). In 2015, survey data were collected (n = 133) at six agricultural conferences Vermont. Participants were asked about their climate change knowledge, perceptions of adaptation, and their intentions to adopt or recommend one or more of the following BMPs: riparian buffers, drainage tiles with constructed wetlands, retention ponds, and silvopasture. In addition, respondents were asked about how well PVZs did or did not clarify their understanding of each BMP and its associated limiting factors. Results from five multivariate ordered logit models show an increase in interest among some agricultural stakeholders in adopting a BMP (among farmers) or recommending a BMP (among agricultural advisors) after seeing a PVZ depicting that practice. Interest in adoption or recommendation of BMPs was also more likely among respondents who believe that it is important for farms to adapt to climate change. Although PVZs are not common in agricultural outreach programs, these results suggest that PVZs are relevant to agricultural education and land-use decision-making, specifically in the domain of climate change adaptation.
Re-reading marine spatial planning through Foucault, Haugaard and others: an analysis of domination, empowerment and freedom

ABSTRACT Marine spatial planning (MSP) has emerged as a radical approach to achieving sustainable development objectives at sea. While critics challenge its avowed radicalness, often through highlighting dominative processes, more insidious mechanisms of restricted agency remain under-elaborated, as are the productive power and potential of planning. This paper offers a more robust and balanced reading of MSP/power. First, drawing on Haugaard, we read MSP as providing actors with dispositional power to act in concert, thus entailing a move from the risks of ‘resource rush’ to structuring, which facilitates predictability and promotes agency. However, MSP’ing may also restrict agency when (1) powerful actors misuse opportunities for concerted action to pursue sectoral goals; (2) planning fantasies and the planner’s cognitive limitation sustain dominative power-relations; and (3) in setting the boundaries of MSP, bias is mobilized in favor of vested interests. We thus deploy Foucault’s notion of freedom, to analyze the relationship between ‘steering’ and resistance subjectivities, and his concept of parrhesias to consider to what extent, an ethico-political planner may contribute towards more equitable processes and outcomes. We conclude that besides the planner, the state as the ultimate authority in MSP must intervene substantively to minimize differentials in the distribution of actors’ social resources.
Teachers Teaching Teachers: The Role of Workplace Peer Effects on Financial Decisions

This paper studies the role of workplace peers in the transmission of information pertinent to an important household financial decision: the mortgage refinancing choice. Exploiting commonalities in teaching schedules of school teachers in Texas to identify peer groups, we find that refinancing activity among teachers’ peers increases their likelihood of refinancing by 20.7%. The effect of peers increases with the potential savings realized upon refinancing and is stronger among younger teachers. Peers also affect teachers’ choice of lender. Overall, our findings suggest that peer interactions greatly reduce a household’s cost of acquiring and processing financial information.

Improving well-being through mobile money: a replication study in Niger

ABSTRACT Around the world, there has been an exponential growth in cash-based programmes as part of social policies. Innovative payment mechanisms, such as mobile money, could have benefits for recipients. An experimental study suggests that the use of mobile money, Zap delivery, might improve intra-household socio-economic dynamics on Niger. Our replication study evaluates the impact of Zap delivery in contrast to more traditional delivery mechanism. We examined original author´s findings and estimated similar results about increasing household diet diversity without decreasing their durable and nondurable assets. The heterogeneity evaluation by age groups suggests that the Zap delivery had a different impact on older beneficiaries than younger ones. In addition, we evaluated the robustness, which considers multiple imputation and Lee bounds analysis; as well as a nutritional evaluation of children under 5 years using anthropometric measures.
The ‘New’ Migration for Work Phenomenon: The Pursuit of Emancipation and Recognition in the Context of Work

This article examines the ‘new’ migration for work phenomenon gripping Southern Europe since the Global Financial Crisis struck in 2008, by focusing on the case of skilled Greeks migrating to Germany for work purposes. In applying Honneth’s concept of emancipation to the domain of work, the article frames emancipation as a phenomenon which emerges from an individual’s search for meaningful work and as a form of resistance to deteriorating institutions and social injustice. Informed by this is an assessment of the new migration for work phenomenon from Greece to Germany by employing survey data on the perceptions of skilled emigrants. Following analysis of the findings, it is concluded that migration is a form of emancipation that allows individuals to regain recognition and self-respect while also to protest the erosion of social and human rights in their home country.
The influence of team social media usage on individual knowledge sharing and job performance from a cross-level perspective

Purpose The purpose of this paper is to examine how team social media usage (SMU) affects two types of knowledge sharing (KS), namely, in-role and extra-role KS, and then individual job performance. The study also examines the mediating effects of two types of KS and the main and moderating effects of team performance norms on individual job performance. Design/methodology/approach This study applies the theory of communication visibility to develop a cross-level model and then validate it through a three-wave survey from 600 individuals in 120 teams. Hierarchical linear model is used to test the hypotheses. Findings The results suggest that team SMU improves team members’ in-role and extra-role KS, and thus enhances their individual job performance. The in-role and extra-role KS have partial mediating effects between team SMU and job performance. The results also show that team performance norms have a positive main effect on individual job performance, but negatively moderate the relationship between individual extra-role KS and job performance. Research limitations/implications This study contributes to the operations management literature by examining the effects of team SMU from a multilevel perspective. Practical implications The findings provide managers with ways to improve individual KS and job performance. Originality/value This study is one of the first to investigate the effects of team SMU on individual KS and job performance. It also identifies the two-sided effects of team performance norms.
Explaining the freedom of information in local government: What influences information disclosure?

This paper analyses the factors that influenced the freedom of information in Spanish municipalities and which explain the levels of information disclosure. A dynamic panel System General Method of Moments (System-GMM) estimation was used to analyses data from 100 Spanish largest municipalities for the period of 2008-2014. The analysis indicates that disclosure of information about municipal management is associated with financial dependence, internet access, unemployment, electoral turnout and political rivalry.
Panic Attack: How Illegitimate Invasions of Privacy Cause Consumer Anxiety and Dissatisfaction

This research fills a gap in the literature regarding face-to-face privacy invasions. Most research in the privacy arena examines information privacy (e.g., credit card and data information) and ignores the privacy component of face-to-face interactions. Using three studies, the authors explore the impact of physical and visual invasions on privacy control. The findings show that only one dimension of privacy needs to be invaded for consumers to feel less control over their privacy. Perceptions of privacy control have a negative relationship with satisfaction, as mediated through feelings of anxiety. Importantly, two invasions do not have a greater impact than one, and a legitimate reason for physical or visual invasions can lessen the negative consequences in terms of anxiety and satisfaction. These results have important theoretical and practical implications for marketers aiming to design satisfying consumption experiences that also preserve consumer welfare.
Location-Based Tracking Data and Customer Movement Pattern Analysis Using for Sustainable Fashion Business

Retailers need accurate movement pattern analysis of human-tracking data to maximize the space performance of their stores and to improve the sustainability of their business. However, researchers struggle to precisely measure customers’ movement patterns and their relationships with sales. In this research, we adopt indoor positioning technology, including wireless sensor devices and fingerprinting techniques, to track customers’ movement patterns in a fashion retail store over four months. Specifically, we conducted three field experiments in three different timeframes. In each experiment, we rearranged one element of the visual merchandising display (VMD) to track and compare customer movement patterns before and after the rearrangement. For the analysis, we connected customers’ discrete location data to identify meaningful patterns in customers’ movements. We also used customers’ location and time information to match identified movement pattern data with sales data. After classifying individuals’ movements by time and sequences, we found that stay time in a particular zone had a greater impact on sales than the total stay time in the store. These results challenge previous findings in the literature that suggest that the longer customers stayed in a store, the more they purchase. Further, the results confirmed that effective store rearrangement could change not only customer movement patterns but also overall sales of store zones. This research can be a foundation for various practical applications of tracking data technologies.
Evaluating Circular Economy under a Multi-Parametric Approach: A Technological Review

A circular economy (CE) is conceptualized under different rounds of materials and energy cycling flows and is a matter of a three-level deployment: inter-enterprise circulation, regional circulation, and social circulation. Regarding them, the aim of this research was to get an update on the current technological advances and the perspectives of its implementation. Thus, a multi-parametric approach has been conducted to analyze the functionality of technologies in wastewater treatment, organic waste management, agrarian development, and food waste in the context of CE. Beside the narrative of the technological view, a critical approach assimilates the environmental, marketing, economic, governmental, and procedural viewpoints and leads to key indicators which are subject to positive and negative externalities. Due to this co-existence, we denoted the complexity of CE principle implementation and the need for specific envisage in each case, while proposing strategies are formulated in the light of social-environmental impact. Finally, further research gaps were proposed for deeper consideration.
Exploring the Weekly Travel Patterns of Private Vehicles Using Automatic Vehicle Identification Data: A Case Study of Wuhan, China

Automatic vehicle identification (AVI) systems collect 24 h vehicle travel data for the efficient management of traffic flows. The automatic vehicle identification data collected by an overhead traffic monitoring system provides a means for understanding urban traffic flows and human mobility. This article explores the weekly travel patterns of private vehicles based on AVI data in Wuhan, a megacity in Central China. We extracted origin–destination information and applied the K-Means clustering algorithm to classify spatial traffic hot spots by camera locations. Subsequently, the Latent Dirichlet Allocation algorithm was used to mine the temporal travel patterns of individual vehicles. The cluster results are summarized in nine travel probability matrixes. The effectiveness of this approach is illustrated by a case study using a large set of AVI data collected from 19 to 24 November 2018, in Wuhan, China. The results revealed six variations of the travel demand on weekdays and weekends—the commuting behaviors of private drivers triggered a tidal change in traffic flows. This study also exposed nine weekly travel patterns for private cars, reflecting temporal similarities of human mobility patterns. We identified four types of commuters. These results can help city managers understand daily changes in urban travel demands.
Tour guides’ perceptions of below-cost tours and managerial implications

Below-cost tours (BCTs) have long been considered a serious issue in the travel industry, yet they have rarely been discussed from a tour guides’ perspective. Today’s tour guides are mostly freelancers, hired by tour operators to lead tour groups. While previous studies cover the management and behaviors of tour guides, there is little insight into personal perceptions of their work. To better understand BCTs, this study provides an intimate look at the phenomenon through the use of semi-structured interviews from tour guides and employment of nonparticipant observation on their experiences. The structural problems of the travel industry and impacts of BCTs on tour guide performance are explored and highlighted. Framed in the agency theory, the managerial implications and solutions to the BCT problems are discussed and recommended.
The times they are a-changin’: party campaign strategies in the 2018 Italian election

Abstract The 2018 Italian election produced striking results, with both a historic success for the two challenger parties (League and M5S) and massive defeats for the two mainstream parties (PD and FI). This article analyses party campaign strategies and their consistency with the opportunity structures provided by the configuration of Italian public opinion. Relying on issue-yield theory, original survey data were collected for both issue support and priority among Italian voters, and party emphases on issues in the electoral campaign – through Twitter data. The findings indicate a generalised ideological inconsistency of the constituencies of the main parties, while campaign strategies appear much more ideologically consistent. Moreover, it is found that parties focused mostly on conflict-mobilisation strategies, rather than on problem solving. Finally, the article shows that, in general, parties acted strategically, by aligning their campaign to the available opportunities, although with relevant variations across parties.
Technology-Intensive Trade, Economic Growth and CO2 Emissions: ARDL Bounds Test Approach and Causality Analysis for BRICS

This study identified long-run and short-run relationship as well as causal direction of medium and high tech (MHT) trade (proxy for tech-intensive trade), economic growth and CO2 emissions in BRICS for the period of 1992-2015 applying ARDL bound test approach and error-correction based Granger causality. The disequilibrium (non-stationary) characteristics of CO2 emissions in China during 1992-2014, along with unavailability of MHT trade data prior to 1992, constrained the analysis of short-run and long-run relationship among the variables for the country. The study found that structural change did not affect CO2 emissions in India and Russia in the long-run but it did in the short-run in India. The study did not find any long-run cointegration among the variables for South Africa. It identified long-run causality running from MHT trade and growth to CO2 emissions for India and Russia, whereas long-run causality directed from MHT trade and CO2 emissions to growth was found in Brazil and India, and causality running from CO2 emissions and growth to MHT trade only held for India.
Koroner Arter Bypass Cerrahisinde Akut Normovolemik Hemodilüsyonun Koagülasyon, Fibrinolitik Sistem, Protein C ve Protein S Üzerine Etkisi THE EFFECT OF ACUTE NORMOVOLEMIC HEMODILUTION ON COAGULATION, FIBRINOLYTIC SYSTEM, PROTEIN C AND S IN CORONARY ARTERY BYPASS SURGERY

Summary Background: Cardiac surgery performing with cardiopulmonary bypass (CPB) causes multiple alterations in the hemostatic system. In this study, we investigated the effect of acute normovolemic hemodilution on coagulation, fibrinolytic system and physiologic anticoagulants such as protein C and S among patients who underwent coronary artery bypass grafting (CABG). Methods: Forty one patients who underwent CABG with (Group 1, n = 20) and without (Group 2, n = 21) acute normovolemic hemodilution were enrolled in this study. Activated clotting time (ACT), prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimer (fibrin degradation product), fibrinogen, protein C and S, and platelet count were measured. Blood samples were collected after induction of anesthesia, 20 minutes after the beginning of CPB, 30 minutes after administration of protamine, and 24 hours after the weaning from CPB. Transfused blood products and mediastinal bleeding were recorded. Results: Within both groups, D-dimer elevated, and protein C values and platelet count decreased significantly at all samples compared with preoperative values. The changes of ACT, PT, aPTT, D-dimer, fibrinogen, protein C and S and platelet count were similar in both groups. There were no statistically significant differences between both groups with respect to the blood transfusion and mediastinal bleeding. Conclusions: Acute normovolemic hemodilution in CABG surgery does not significantly decrease blood products requirements and the changes in hemostatic system are not effected by this technique.
Compensation consultants’ reputation, non-compensation consulting services and CEO pay

ABSTRACT In this study, we draw on the reputation and product quality literature to examine whether compensation consultants with higher reputation have incentives to provide higher-quality services in terms of CEO pay level and pay performance sensitivity (PPS). Using 1,827 US firm-year observations for 2009 and 2010, we find that consulting firms with a higher reputation, proxied by consultant size, are associated with lower compensation and higher PPS. We also find that the PPS for consultants that also provide non-compensation-related services (NCS) is significantly positive for consultants with a higher reputation, consistent with the reputation protection explanation, and significantly negative for the other consultants with a lower reputation consistent with the conflict of interest argument.
