Does Who We Are Influence What We Say? The Impact of Organizational Identity on Responses to Ethical Issues

Business organizations frequently face ethical issues which may lead stakeholders to question the competence or integrity of organizational actors. In such cases, the way the organization communicates with its stakeholders can play a critical role in preserving or restoring organizational reputation, financial performance, and trust. Thus, understanding factors that influence organizational communication in the wake of ethical issues is important. Previous research has focused on the impact of situational characteristics on organizational responses and stakeholder reactions to those responses but has not explored the role that organizational characteristics play in shaping firms\u27 responses to ethical issues. The current study seeks to understand how organizational characteristics influence responses to ethical issues. The focus of the paper is the initial communicative response, defined as the first public statement made by an organization regarding an issue which may be perceived as an ethical one. This study examines responses to one type of ethical issue which many companies face - financial restatements. The outcomes of interest in this study are the prominence and informativeness of restatement announcements made by organizations after learning of a need to correct previous financial misstatements. Hypotheses focus on the influence of organizational characteristics on restatement announcements, using an organizational identity framework. Specifically, it is predicted that organizational identity orientation and the extent to which social responsibility is included in the content of an organization\u27s identity will shape managers\u27 perceptions of and responses to ethical issues. Results provide evidence of a relationship between a relational/collectivistic OIO and the informativeness of a firm\u27s initial restatement announcement as well as a positive correlation between the magnitude of the restatement and the informativeness of the restatement announcement. Results also show a significant negative interaction between a relational/collectivistic OIO and the magnitude of the restatement in predicting the amount of information provided. The interaction between commitment to social responsibility and the magnitude of the restatement in predicting the informativeness of the announcement is marginally significant and positive. Taken together, these findings provide evidence that organizational characteristics can influence responses to ethical issues and also interact with situational factors to further influence responses to these issues

Health systems thinking : the need for a more critical approach

The present study intends to bring more insights and added value to health systems thinking using systems ideas. It inquires about the current state of health systems thinking, analyses different strengths of alternative systems approaches, and suggests what systems thinking can offer in order to improve the current understanding and the technical performance of health systems. It does not intend to develop a blue print model but rather a more critical approach to deal with some of the intractable problems encountered in current health sector reforms. The thesis is not expected to serve public health practitioners only but also systems thinking theorists, particularly those interested in social systems and pluralism in management sciences. Specifically, this thesis aims at analysing the current state of Health systems thinking; explores what other systems approaches can offer to enlighten health systems; and yields knowledge on critical health systems thinking. To achieve these aims the researcher articulated the study on the basis of the definition of health by the World Health Organisation, the interconnectedness among key health determinants and the global health challenges with particular emphasis in Sub-Saharan Africa. Critical systems thinking is the theoretical framework in which knowledge about systems is expressed and the current state of Health systems thinking is the area of concern in relation to which the researcher has aspirations. The methodology consists in two major steps conducting thought experiments in the context of three scenarios from the researcher's own experience. The first step uses Jackson's four major systems approaches and associated methodologies and yields learning about the current state of health systems thinking; and the second step, using critical systems practice in mode 2, generates a more critical approach to health systems thinking

Juries, Social Norms, and Civil Justice

At the root of many contemporary debates and landmark cases in the civil justice system are underlying questions about the role of the civil jury. In prior work, I examined the justifications for the civil jury as a political institution, and found them wanting in our contemporary legal system. This Article looks closely and critically at the justification for the civil jury as an adjudicative institution and questions the conventional wisdom behind it. The focus is on tort law because the jury has more power to decide questions of law in tort than any other area of law. The Article makes three original contributions.

Managing social risk through stakeholder partnership building : empirical descriptive process analysis of stakeholder partnerships from British Petroleum in Colombia and Hoechst in Germany for the management of social risk

This thesis sets out to provide a systematic study of stakeholder partnership building of BP in Colombia and Hoechst in Germany in the context of social risk management. Each company built an NGO and a community partnership that became an integral part of firms' strategy. In examining and evaluating the two companies and the four stakeholder partnerships, the leading research question of how firms build stakeholder partnerships is answered. The present study seeks to identify the characteristics of stakeholder partnership building, as well as to isolate the similarities and differences of this process. Additionally, it is an attempt to define the features of the firms' social risk navigation as context of this research project. The thesis is divided into four parts. The first part introduces the research phenomenon, reviews conceptual foundations, and elaborates methodological issues. The case studies of BP and Hoechst are subdivided into internal processes of social integration and reintegration with regard to the two companies, and external processes of partnership building with regard to the four stakeholder partnerships that are chronologically presented in part two. Part three conceptualises stakeholder partnership building in terms of navigating social risk and partnership alchemy. Finally, part four comprises the research synopsis and reflection. Business and society, stakeholder theory, and strategic relationships are the theoretical areas that contributed to the framework for analysing partnership building. Two longitudinal in-depth case studies provide qualitative data for the processual analysis. The empirical data are categorised, aggregated and compared, in order to extract research findings. The contribution of this research is the extension of behavioural stakeholder theory. It develops is a stakeholder partnership building theory that comprises three parts. First, the 4-Ps of stakeholder partnership building are identified. Second, variables are isolated that describe these elements of partnership alchemy. Finally, four patterns of stakeholder partnership building are identified. As a result, the research presents four propositions for partnership building. Based on the analysis of firms' navigation of social risk, a fifth proposition distinguishes between firm-specific and partnership-specific partnership building. The empirical data provides a contribution to knowledge in its own right by providing detailed insight into the practice of social risk management through stakeholder partnership building

The cropping-plan decision-making : a farm level modelling and simulation approach

L'assolement' c'est à dire l'attribution des cultures sur les différentes parcelles de l'exploitation agricole' est un élément fondamental de la stratégie de l'agriculteur. Il provient d'un équilibre entre des contraintes et objectifs multiples alliant les dimensions sociale' économique' agronomique et environnementale (utilisation des ressources). Il reflète deux dimensions: une dimension stratégique (lié aux orientations de l'exploitation) et une dimension tactique plus lié à l'adaptation des attributions suite à des contextes changeant (climatique' prix). Afin représenter ces deux niveaux et ainsi structurer les enjeux relatifs aux choix d'assolement à l'échelle de l'exploitation nous proposons une approche basées sur : i) une analyse du processus décisionnel par le biais d'enquêtes en exploitation; ii) une modélisation dynamique aussi bien sur des processus biophysiques (modèles de culture) que sur des processus de gestion (modèle de décision) pour comprendre et simuler. ABSTRACT : Evolutions of the institutional and environmental contexts are driving search for alternative cropping systems to reduce water use while maintaining high levels of productivity. This thesis is an account of the long tradition of research on cropping-plan choices at the farm level. It concerns the scope of modelling agricultural systems with an opening to economy. The objective of the research described in this thesis is to produce formalised knowledge on farmers’ croppingplan choices under uncertain environment (price and weather) by analysing and modelling their decision-making processes. Formalising and modelling decision-making processes is becoming a crucial point to develop decision support systems that go beyond limitations of formerly developed prescriptive approaches. This thesis contributes to the development of a formalised and integrated methodology to study and model complex decision-making process. This methodology enables to fill the gap between field surveys and decision-model implementation. The methodology is drawn upon a theoretical background of the decision-making' and consistently combined tools to respectively survey' analyse' model and implement coupled agent and biophysical models. In this thesis' I address the question of uncertainty in two directions. I first analyse the spatio-temporal dynamic of individual farmers’ decision-making process. Then I estimate farmers’ aversion to risk by comparing stated and revealed elicitation methods. On the basis of field survey results' I develop a decision model called CRASH. The approach to develop the model stresses on explicit formalisation of the decision-making process in its temporal and spatial dimensions' and representation of the domain knowledge through generic concepts that are close to ones used by decision-makers. The implementation of developed models is carried out on the RECORD platform as trail blazing project. The originality relies on the use of dynamic models on both the biophysical and management processes. This research opens new perspectives for developing farm specific decision support systems that are based on simulating farmers’ decisionmaking processes. The modelling and simulating the cropping-plan decision-making processes should enable to design with farmers cropping systems that re-conciliate the required adaptive capacities and needs to maintain cropping systems productivity

Nature-inspired survivability: Prey-inspired survivability countermeasures for cloud computing security challenges

As cloud computing environments become complex, adversaries have become highly sophisticated and unpredictable. Moreover, they can easily increase attack power and persist longer before detection. Uncertain malicious actions, latent risks, Unobserved or Unobservable risks (UUURs) characterise this new threat domain. This thesis proposes prey-inspired survivability to address unpredictable security challenges borne out of UUURs. While survivability is a well-addressed phenomenon in non-extinct prey animals, applying prey survivability to cloud computing directly is challenging due to contradicting end goals. How to manage evolving survivability goals and requirements under contradicting environmental conditions adds to the challenges. To address these challenges, this thesis proposes a holistic taxonomy which integrate multiple and disparate perspectives of cloud security challenges. In addition, it proposes the TRIZ (Teorija Rezbenija Izobretatelskib Zadach) to derive prey-inspired solutions through resolving contradiction. First, it develops a 3-step process to facilitate interdomain transfer of concepts from nature to cloud. Moreover, TRIZ’s generic approach suggests specific solutions for cloud computing survivability. Then, the thesis presents the conceptual prey-inspired cloud computing survivability framework (Pi-CCSF), built upon TRIZ derived solutions. The framework run-time is pushed to the user-space to support evolving survivability design goals. Furthermore, a target-based decision-making technique (TBDM) is proposed to manage survivability decisions. To evaluate the prey-inspired survivability concept, Pi-CCSF simulator is developed and implemented. Evaluation results shows that escalating survivability actions improve the vitality of vulnerable and compromised virtual machines (VMs) by 5% and dramatically improve their overall survivability. Hypothesis testing conclusively supports the hypothesis that the escalation mechanisms can be applied to enhance the survivability of cloud computing systems. Numeric analysis of TBDM shows that by considering survivability preferences and attitudes (these directly impacts survivability actions), the TBDM method brings unpredictable survivability information closer to decision processes. This enables efficient execution of variable escalating survivability actions, which enables the Pi-CCSF’s decision system (DS) to focus upon decisions that achieve survivability outcomes under unpredictability imposed by UUUR
