This is a brief and accessible introduction to the thought of the great Franciscan theologian St. Bonaventure (c. 1217-74). Cullen focuses on the long-debated relation between philosophy and theology in the work of this important but neglected thinker, revelaing Bonaventure as a great synthesizer. Cullen's exposition also shows in a new and more nuanced way Bonaventure's debt to Augustine, while making clear how he was influenced by Aristotle. The book is organized according to the categories of Bonaventure's own (...) classic text. De reductione artium ad theologiam. Part I is devoted to the definition of Christian Wisdom. In Part II, "The Light of Philosophical Knowledge," individual chapters are devoted to Bonaventure's physics, metaphysics, and moral philosophy. Part III, "The Light of Theological Knowledge," includes chapters on the Trinity, Creation, Sin, the Incarnation, Grace, the Sacraments, and the Last Things. (shrink)

Businesses and the social sciences are increasingly facing calls to further scholarship dedicated to understand sustainability. Furthermore, multinationals are also facing similar calls given their high profile and their role in environmental degradation. However, a literature review shows that there is very limited understanding of sustainability at a cross-national level. Given the above gaps, we contribute to the literature by examining how selected GLOBE [House et al., Culture, leadership and organizations: The GOBE study of 62 societies. Sage Publications, Thousand Oaks, (...) 2004 ] cultural dimensions are related to individuals’ propensity to support sustainability initiatives in 33 countries. We use data from the World Values Survey [World Values Study Group, World Values Surveys and European Value Surveys, 1999–2001. Inter-University Consortium for Political and Social Research, Ann Arbor, 2004 ] and test our hypotheses using Hierarchical Linear Modeling (HLM). Results support all but one hypothesis. Specifically, uncertainty avoidance is not related to propensity to support sustainability initiatives. In contrast, performance orientation and assertiveness have the desired negative relationship with our dependent variable while collectivism, future orientation, and human orientation have the desired positive relationship. We discuss the conceptual and practical implications of this study. (shrink)

Prediction of long-lived anomalous behaviour in the atmosphere is fundamental to extended range and seasonal forecasting. Prediction of changes in the climatology of such anomalous behaviour is also fundamental to regional climate modelling. Anomalous atmospheric behaviour is often related to mid-latitude tropospheric ‘blocking’ patterns, where the normal westerly flow associated with the temperature difference between the Poles and the Equator is disrupted. Following recent work on stratosphere–troposphere coupling, we show that the vertical structure of the atmosphere can strongly influence the (...) climatology of tropospheric blocking. We invoke dynamical theory to argue that the development and decay of anomalous circulations is most efficient for a preferred aspect ratio of the flow, implying that the development of large-scale anomalies requires a large vertical scale. Evidence for this link comes from the observed evolution of the geopotential height. In particular, we find that the development of the large-scale tropospheric anomalies associated with blocking requires a vertical scale extending well into the stratosphere. This process is inhibited during periods of high stratospheric activity, when the vertical scale of tropospheric developments is restricted, leading to the persistence of large horizontal scales.

Diagnoses of circulations in the vertical plane provide valuable insights into aspects of the dynamics of the climate system. Dynamical theories based on geostrophic balance have proved useful in deriving diagnostic equations for these circulations. For example, semi-geostrophic theory gives rise to the Sawyer–Eliassen equation (SEE) that predicts, among other things, circulations around mid-latitude fronts. A limitation of the SEE is the absence of a realistic boundary layer. However, the coupling provided by the boundary layer between the atmosphere and the (...) surface is fundamental to the climate system. Here, we use a theory based on Ekman momentum balance to derive an SEE that includes a boundary layer (SEEBL). We consider a case study of a baroclinic low-level jet. The SEEBL solution shows significant benefits over Ekman pumping, including accommodating a boundary-layer depth that varies in space and structure, which accounts for buoyancy and momentum advection. The diagnosed low-level jet is stronger than that determined by Ekman balance. This is due to the inclusion of momentum advection. Momentum advection provides an additional mechanism for enhancement of the low-level jet that is distinct from inertial oscillations. (shrink)

The societal need for reliable climate predictions and a proper assessment of their uncertainties is pressing. Uncertainties arise not only from initial conditions and forcing scenarios, but also from model formulation. Here, we identify and document three broad classes of problems, each representing what we regard to be an outstanding challenge in the area of mathematics applied to the climate system. First, there is the problem of the development and evaluation of simple physically based models of the global climate. Second, (...) there is the problem of the development and evaluation of the components of complex models such as general circulation models. Third, there is the problem of the development and evaluation of appropriate statistical frameworks. We discuss these problems in turn, emphasizing the recent progress made by the papers presented in this Theme Issue. Many pressing challenges in climate science require closer collaboration between climate scientists, mathematicians and statisticians. We hope the papers contained in this Theme Issue will act as inspiration for such collaborations and for setting future research directions. (shrink)

The purpose of this study was to determine whether the ethical climate dimensions identified by Victor and Cullen (1987, 1988) could be replicated in the subunits of a multi-unit organization and if so, were the dimensions associated with particular types of operating units. We identified three of the dimensions of ethical climate found by Victor and Cullen and also found a new dimension of ethical climate related to service. Partial support was found for Victor and Cullen's hypothesis (...) that certain ethical climate dimensions are associated with particular forms of organizational governance and control. (shrink)

Victor and Cullen (1988) identified several dimensions of ethical climate that exist in organizations and organizational subunits. We tested the relationship between these dimensions of ethical climate and ethical behavior at different levels of analysis. Using Within and Between Analysis (WABA) (cf. Dansereau, Alutto and Yammarino, 1984), partial support was found for a relationship between dimensions of ethical climate and ethical behavior.

This paper studies the relationship between organizational ethical climate and the forms of organizational citizenship behavior (OCB), including in-role and extra-role behaviors, and examines the mediating effect of employee loyalty. A sample of employees from a traditional Hong Kong-based company was used as a study group. The purpose of this study was to examine the causes and implications of how various ethical work climates affect employee performance. Based on a model proposed by Victor and Cullen, ethical climate is arranged (...) from lower levels to higher levels. The results suggest that lower levels of ethical climate (instrumentality and independence), characterizing a weak relational contract between employee and employer, are associated with negative extra-role behavior. In contrast, higher levels of ethical climate (caring and law-and-code), symbolic of a strong relational contract at work, are associated with positive extra-role behavior. Moreover, normative commitment mediated a positive relationship between caring and identification with the company, whereas attitudinal loyalty mediated the negative relationship between independence and altruism. Implications for future research and practice are discussed. (shrink)
