The paper investigates how energy-intensive industries respond to the recent government-led carbon emission schemes through the content analysis of 306 annual and standalone reports of 25 UK listed companies from 2004 to 2012. This period of reporting captures the trend and development of corporate disclosures on carbon emissions after the launch of EU Emissions Trading Schemes (ETS) and Climate Change Act (CCA) 2008. It is found that in corresponding to strategic legitimacy theory, there is an increase in both the quality and quantity of carbon disclosures as a response to these initiatives. However, the change is gradual, which reflects in the achievement of peak disclosure period two years after the launch. It indicates that the new legislations have a lasting impact on the discourses rather than an immediate legitimacy threat from the perspective of institutional legitimacy theory. The results also show that carbon disclosures are an institutionalised practice as companies in the same industries and/or with same carbon trading account status appear to imitate and adopt the industry’s ‘best practice’ disclosure strategy to maintain legitimacy. The trend analysis suggests that the overall disclosure practice is still in its infant stage, especially in the reporting of quantitative and monetary items. The paper contributes to the social and environmental accounting literature by adopting both strategic and institutional view of legitimacy, which explains why carbon disclosures evolve in a specific way to meet the expectation of various stakeholders.

This paper discusses the use of the Trans-theoretical Model of Behavior Change in the treatment of sex offenders. Constructs within this theory are the Stages of Change, Processes of Change and Decisional Balance. The first section of this paper provides a brief description of these constructs. The second section provides a brief review of research related to these constructs and discusses the implications of this research in relation to the treatment of sex offenders. The third section of this paper provides a practical description of the use of the constructs of the Trans-theoretical Model of Behaviour Change in the treatment of sex offenders. Although the validity of this model among sex offenders requires further investigation, the Trans-theoretical Model of Behavior Change appears to have considerable utility as an overarching theoretical model to conceptualize and facilitate behavior change among sex offenders.

Resource management decisions influence not only the output of the economy but also the distribution of utility between groups within the community. The theory of Benefit Cost Analysis provides a means of incorporating this distributional change through the application of distributional or welfare weights. This paper reports the results of research designed to estimate distributional weights suitable for inclusion in a Benefit Cost Analysis framework. The findings of a choice modelling experiment estimating community preferences with respect to intergenerational utility distribution are presented to illustrate this innovative application of a stated preference technique.

Background Subjective wellbeing (SWB) in people with intellectual disabilities has been the focus of increased interest in the identification of support needs and as an outcome measure for interventions and service delivery evaluations. It is therefore important to conduct further research in this area, and to develop appropriate scales to measure SWB.

Methods A new scale, the Personal Wellbeing Index-Intellectual Disability (PWI-ID) was administered to 114 adults with mild (n = 82) or moderate (n = 32) level ID in Victoria, Australia.

Results The PWI-ID demonstrated good reliability and validity. A comparison of the findings with previous research indicates that participants' SWB levels are within the normative range, and are similar to those reported by the general population.

Conclusions The results support the notion that individuals with ID do not experience life quality lower than normal, which can be explained theoretically by the Theory of Subjective Wellbeing Homeostasis. The use of the PWI-ID may ultimately assist in ensuring that the needs of people with ID are being met and inform the planning and delivery of congruent resources and services.

Cosmopolitan scholarship has been at the forefront of efforts to consider political structures capable of realising justice in a more robust manner than prevailing global governance arrangements. In particular, the arguments of Thomas Pogge have contributed significantly to scholarly thinking about global poverty and his scheme of 'institutional cosmopolitanism' aspires to institutionalise human rights in the structures of global governance. This essay critiques the capacity of Pogge's cosmopolitan approach to productively guide political action in relation to global poverty by questioning whether global institutions generated by human rights are sufficient to address global poverty. The argument in this essay is that a viable guide to political action which alleviates global poverty must also take account of the potential utility of the state. This essays draws upon republican ideas to contend that cosmopolitanism needs to encompass a robust account of local institutions such as the state.

This paper presents a method for conducting dynamic due diligence to evaluate Mergers and Acquisitions; demonstrates its effectiveness in a particular case; and extrapolates its theoretical and practical implications to the general case. It may be called the ‘ECIPP’ method - an acronym for: Establishing mandates; Creating projections; Identifying issues; Prioritizing procedures and Performing them.

Two established alternative due diligence methods are examined. The prevailing finance-theory-based procedure has the virtues of simplicity and elegance; the vice is abstraction. The prevailing practitioner-based regime has the virtues of thoroughness and concreteness but the vices of rigidity and inefficiency. Resolving the tradeoffs inherent in both static prescriptions provides an opportunity for a dynamic, innovative approach derived from grounded theory and an application of Hindle’s (1993) theory of venture renaissance through application of an enhanced paradigm of Entrepreneurial Business Planning. The ECIPP method retains simplicity, concreteness and thoroughness but eliminates abstraction, rigidity and inefficiency.

This is demonstrated in a case. ChildCo’s CEO had only one month to complete his M&A evaluation; no expertise or previous experience; severely limited budget for the exercise and had been flatly informed by prevailing M&A experts that what he wanted could not be done. Using the ECIPP method, the CEO and the author did it: on time, within budget and to the satisfaction of a previously skeptical board of one of the world’s largest multi-national companies including arguably the world’s most professional corporate M&A division.

The replicability logic of the case research permits two generalisations. (1) ECIPP extends the range and utility of Entrepreneurial Business Planning as a management technology, well beyond the constraints to which it is usually confined. (2) The ECIPP method of dynamic due diligence is an innovation worthy of mature consideration and further investigation by theorists and practitioners in the M&A field, in the disciplines of both Finance and Entrepreneurship and, well beyond, in the realms of general management theory, methodology and practice.

It has often been argued that there exists an underlying biological basis of utility functions. Taking this line of argument a step further in this paper, we have aimed to computationally demonstrate the biological basis of the Black-Scholes functional form as applied to classical option pricing and hedging theory. The evolutionary optimality of the classical Black-Scholes function has been computationally established by means of a haploid genetic algorithm model. The objective was to minimize the dynamic hedging error for a portfolio of assets that is built to replicate the payoff from a European multi-asset option. The functional form that is seen to evolve over successive generations which best attains this optimization objective is the classical Black-Scholes function extended to a multiasset scenario.

Business process designers are increasingly being challenged to develop processes that are not only useful in achieving business objectives but also accepted by the process participants and followed in the work place. Those objectives can only be achieved when both the business and the social/cultural aspects of the specific business environment are taken into account. Humans are not unaided individuals separated from a social group and from supporting artefacts but they are complemented by the environment in which they live in. This paper presents a novel framework for the design of business processes based on the application of activity system, providing a comprehensive framework of humans acting in the world, and the theory of affordances, representing action opportunities offered by the environment. The contribution of this paper is two-fold. First, it provides a theoretical contribution to affordance studies by offering a conceptual model that consolidates new developments in the concept, post Gibson. Second, it introduces a new framework (Activity/Affordance Framework - AAF) to aid the design of business processes. Finally, a case study is used to illustrate the utility of the framework in design practice.

The article argues that the theoretical framework presented by the Copenhagen School is currently unsuited to empirical studies outside the West owing to two factors. First, the presence of the ‘Westphalian straitjacket’ has prevented explicit interrogation of the normative concepts underlying the framework: there is a presumption that European understandings of society and the state are universal. Second, the centrality of the speech-act for securitization to the exclusion of other forms of expression, such as physical action, results in the theoretical framework producing a Westernized description of a given situation. The extent to which these factors limit the utility of the concepts of securitization and societal security in a non-Western setting is illustrated through the case of the overthrow of the government in Kyrgyzstan in March 2005. This example forms an empirical critique to highlight how theoretical shortcomings result in a simplified and Westernized description of the situation that does not take into account the specific local socio-political context. The article concludes that if the Copenhagen School’s theoretical framework is to be considered suitable for universal application, future theoretical developments must explicitly address the issues discussed to enable progress in escaping International Relations’ Westphalian straitjacket.

Workplace training is a key strategy often used by organisations to optimise performance. Further, trainee motivation is a key determinant of the degree to which the material learned in a training programme will be transferred to the workplace, enhancing the performance of the trainee. This study investigates the relationship between several components of the Revised Human Resource Development (HRD) Evaluation and Research Model. This model provides a framework for diagnosing and understanding the causal influences of HRD intervention outcomes on training effectiveness. Data were obtained from an online questionnaire completed by 105 employees of various organisations. Findings revealed that affective organisational commitment, job involvement and utility perceptions are predictors of motivation to learn and transfer learning. An interaction effect was found, with increased affective organisational commitment predicting greater motivation to learn when training was of lower perceived utility. These findings suggest that the design and delivery of training should emphasise the relevance and utility of the programme in order to encourage greater trainee motivation and maximise return on investment. Additionally, implementing strategies aimed at promoting organisational commitment would appear beneficial.

Moral norms and anticipated regret are widely used extensions to the theory of planned behaviour, yet there is some evidence to suggest that these constructs may conceptually overlap as predictors of intention. Two health-related behaviours with distinct moral implications (Study 1: organ donation registration, N = 352 and Study 2: condom usage, N = 1815) were therefore examined to ascertain whether moral norms and anticipated regret are indeed conceptually distinct. While evidence consistent with conceptual overlap was identified in Study 1, the evidence for such overlap in Study 2 was more ambiguous. In Study 3, a meta-analysis of existing literature revealed that the relationship between moral norms and anticipated regret was moderated by the extent of the moral implications arising from the behaviour under examination. Taken together, these findings suggest that conceptual overlap between moral norms and anticipated regret is more likely to occur among behaviours with obvious moral implications. Researchers wishing to examine the predictive utility of moral norms and anticipated regret among such behaviours would therefore be advised to aggregate these measures to form a composite variable (personal norms).

This chapter examines the nature and role of theory in criminal justice evaluation. A distinction between theories of and theories for evaluation is offered to clarify what is meant by ‘theory’ in the context of contemporary evaluation practice. Theories of evaluation provide a set of prescriptions and principles that can be used to guide the design, conduct and use of evaluation. Theories for evaluation include programme theory and the application of social science theory to understand how and why criminal justice interventions work to generate desired outcomes. The fundamental features of these three types of theory are discussed in detail, with a particular focus on demonstrating their combined value and utility for informing and improving the practice of criminal justice evaluation

This paper critically analyzes the use of Absorptive Capacity (ACAP) theory in information systems (IS) research. Drawing on a comprehensive review of the evolution of ACAP theory and models for the construct, we empirically investigate a number of ACAP-related papers published in reputable IS journals. The analysis involves four main areas: 1) summary analysis of ACAP in IS papers; 2) domains of ACAP usage; 3) analysis of hypotheses to show how ACAP is being used to explain various organizational phenomena in IS research; and 4) analysis of measures to gain insights into the operationalization of ACAP in IS research. This research advocates that organization-level ACAP should be applied as the dependent variable in studying the impact of IS. Furthermore, ACAP should be conceptualized as a “capability,” rather than an “asset.” This paper contributes to IS and ACAP studies by investigating and clearly specifying the utility of ACAP in IS research.

We develop portfolio choice theory taking into consideration the first p~ moments of the underIying assets distribution. A rigorous characterization of the opportunity set and of the efficient portfolios frontier is given, as well as of the solutions to the problem with a general utility function and short sales allowed. The extension of c1assical meanvariance properties, like two-fund separation, is also investigated. A general CAPM is derived, based on the theoretical foundations built, and its empirical consequences and testing are discussed
