A companison of socially responsible and conventional investors

Socially responsible investment is a rapidly emerging phenomenon within the field of personal investment. However, the factors that lead investors to choose socially responsible investment products are not well understood, especially in an Australian context. This study provides a comparative examination of conventional and socially responsible investors, with the aim of identifying such factors. A total of 55 conventional investors and 54 ethical investors participated in the study by completing mailed questionnaires about their investment and general behaviour and their attitudes and beliefs. Results indicated some important differences between socially responsible and conventional investors in their beliefs of the importance of ethical issues, their investment decision-making style, and their perceptions of moral intensity. These results support the notion that socially responsible investors differ in critical ways to conventional investors, and are discussed in terms of theoretical and practical implications.

Separation and hedging results with state-contingent production

A state-contingent model of production under uncertainty is developed and compared with more traditional models of production under uncertainty. Producer behaviour with both production and price risk, in the presence and in the absence of futures and forward markets, is analysed in this state-contingent framework. Conditions for the optimal hedge to be positive or negative are derived. We also show that, under plausible conditions, a risk-averse producer facing price uncertainty and the ability to hedge price risk will never willingly adopt a nonstochastic technology. New separation results, which hold in the presence of both price and production risk, are then developed. These separation results generalize Townsend's spanning results by reducing the number of necessary forward markets by one.

Virtual Model Control of a Biped Walking Robot

The transformation from high level task specification to low level motion control is a fundamental issue in sensorimotor control in animals and robots. This thesis develops a control scheme called virtual model control which addresses this issue. Virtual model control is a motion control language which uses simulations of imagined mechanical components to create forces, which are applied through joint torques, thereby creating the illusion that the components are connected to the robot. Due to the intuitive nature of this technique, designing a virtual model controller requires the same skills as designing the mechanism itself. A high level control system can be cascaded with the low level virtual model controller to modulate the parameters of the virtual mechanisms. Discrete commands from the high level controller would then result in fluid motion. An extension of Gardner's Partitioned Actuator Set Control method is developed. This method allows for the specification of constraints on the generalized forces which each serial path of a parallel mechanism can apply. Virtual model control has been applied to a bipedal walking robot. A simple algorithm utilizing a simple set of virtual components has successfully compelled the robot to walk eight consecutive steps.

Emociones y toma de decisiones éticas: desarrollo e implicaciones para la empresa

Los líderes organizacionales se deben enfrentar a retos ambientales del mundo de los negocios y diversas presiones que los ponen día a día en un alto riesgo ético. Sortear dichos riesgos ha demandado cambios sustanciales en las dinámicas de las organizaciones contemporáneas, por lo que las exigencias a los directivos de tomar decisiones acertadas en situaciones de alta complejidad moral son cada vez mayores. Estas decisiones involucran un comportamiento ético de quien las toma, lo cual a su vez está mediado por sus emociones.

EAD: O POLO DE APOIO PRESENCIAL COMO ESPAÇO ORGANIZADOR DA AÇÃO EDUCATIVO-CULTURAL

Esta pesquisa estuda a organização e estruturação de três polos de apoio presencial ligados a modalidade a distância, bem como os processos de gestão e autonomia no contexto em que atuam. Trata-se, portanto, de dois momentos de análise, considerando que o primeiro se relaciona a um estudo descritivo-exploratório no que se refere a organização e estruturação dos polos, a partir de diretrizes preestabelecidas e da discussão sobre a realidade cultural e, ao mesmo tempo contingencial existente neste espaço; o segundo, relacionado à utilização da técnica da entrevista para a análise do processo de gestão e autonomia existente nos polos pesquisados. Para a aplicação da pesquisa, foram realizadas visitas aos polos de apoio presencial (dois localizados no Estado de São Paulo e um no Estado do Paraná) e entrevistas com seus coordenadores, sendo importante destacar que dois destes polos estão ligados à realidade privada e um deles à realidade pública. Respectivamente, tais análises e entrevistas indicaram que apesar das diretrizes preestabelecidas, os polos pesquisados possuem um modelo contingencial e, portanto, cultural de adaptação à realidade em que se instalam; sendo que no caso das entrevistas semiestruturadas e, respectivamente do processo de gestão, existe uma proposta clara por parte dos coordenadores no exercício em se fazer EAD, compreendendo assim, uma gestão voltada a adequações e readequações diante de um contexto em constante desenvolvimento. No que se refere ao processo de autonomia, os fatores que merecem atenção estão diretamente relacionados à compreensão dos sujeitos sobre a existência de trâmites não negociáveis, respectivamente relacionados às bases legais que regulamentam a existência dos polos de apoio presencial, contudo, estabelecidos estes parâmetros, a autonomia se determina pela tomada de decisão deste gestor diante da realidade em que se instala.

The Once and future pioneers? : the role of voluntary organizations in innovation in the personal social services

This thesis explores the innovative capacity of voluntary organizations in the field of the personal social services. It commences with a full literature review, which concludes that the wealth of research upon innovation in the organization studies field has not addressed this topic, whilst the specialist literatures upon voluntary organizations and upon the personal social services have neglected the study of innovation. The research contained in this thesis is intended to right this neglect and to integrate lessons from both fields. It combines a survey of the innovative activity of voluntary organizations in three localities with cross-sectional case studies of innovative, developmental and traditional organizations. The research concludes that innovation is an important, but not integral, characteristic of voluntary organizations. It develops a contingent model of this innovative capacity of voluntary organizations, which stresses the role of external environmental and institutional forces in shaping and releasing this capacity. It concludes by considering the contribution of this model both to organization studies and to the study of voluntary organizations.

A quantitative approach to the organizational design problem

The span of control is the most discussed single concept in classical and modern management theory. In specifying conditions for organizational effectiveness, the span of control has generally been regarded as a critical factor. Existing research work has focused mainly on qualitative methods to analyze this concept, for example heuristic rules based on experiences and/or intuition. This research takes a quantitative approach to this problem and formulates it as a binary integer model, which is used as a tool to study the organizational design issue. This model considers a range of requirements affecting management and supervision of a given set of jobs in a company. These decision variables include allocation of jobs to workers, considering complexity and compatibility of each job with respect to workers, and the requirement of management for planning, execution, training, and control activities in a hierarchical organization. The objective of the model is minimal operations cost, which is the sum of supervision costs at each level of the hierarchy, and the costs of workers assigned to jobs. The model is intended for application in the make-to-order industries as a design tool. It could also be applied to make-to-stock companies as an evaluation tool, to assess the optimality of their current organizational structure. Extensive experiments were conducted to validate the model, to study its behavior, and to evaluate the impact of changing parameters with practical problems. This research proposes a meta-heuristic approach to solving large-size problems, based on the concept of greedy algorithms and the Meta-RaPS algorithm. The proposed heuristic was evaluated with two measures of performance: solution quality and computational speed. The quality is assessed by comparing the obtained objective function value to the one achieved by the optimal solution. The computational efficiency is assessed by comparing the computer time used by the proposed heuristic to the time taken by a commercial software system. Test results show the proposed heuristic procedure generates good solutions in a time-efficient manner.

Protesting or justifying? A latent class model for contingent valuation with attitudinal data

This article develops a latent class model for estimating willingness-to-pay for public goods using simultaneously contingent valuation (CV) and attitudinal data capturing protest attitudes related to the lack of trust in public institutions providing those goods. A measure of the social cost associated with protest responses and the consequent loss in potential contributions for providing the public good is proposed. The presence of potential justification biases is further considered, that is, the possibility that for psychological reasons the response to the CV question affects the answers to the attitudinal questions. The results from our empirical application suggest that psychological factors should not be ignored in CV estimation for policy purposes, allowing for a correct identification of protest responses.

The effects of language complexity in a counterattitudinal appeal to laypeople : an application of the elaboration likelihood model of persuasion to a legal issue

The effects of a complexly worded counterattitudinal appeal on laypeople's attitudes toward a legal issue were examined, using the Elaboration Likelihood Model (ELM) of persuasion as a theoretical framework. This model states that persuasion can result from the elaboration and scrutiny of the message arguments (i.e., central route processing), or can result from less cognitively effortful strategies, such as relying on source characteristics as a cue to message validity (i.e., peripheral route processing). One hundred and sixty-seven undergraduates (85 men and 81 women) listened to eitller a low status or high status source deliver a counterattitudinal speech on a legal issue. The speech was designed to contain strong or weak arguments. These arguments were 'worded in a simple and, therefore, easy to comprehend manner, or in a complex and, therefore, difficult to comprehend manner. Thus, there were three experimental manipulations: argument comprehensibility (easy to comprehend vs. difficult to comprehend), argumel11 strength (weak vs. strong), and source status (low vs. high). After listening to tIle speec.J] participants completed a measure 'of their attitude toward the legal issue, a thought listil1g task, an argument recall task,manipulation checks, measures of motivation to process the message, and measures of mood. As a result of the failure of the argument strength manipulation, only the effects of the comprehel1sibility and source status manipulations were tested. There was, however, some evidence of more central route processing in the easy comprehension condition than in the difficult comprehension condition, as predicted. Significant correlations were found between attitude and favourable and unfavourable thoughts about the legal issue with easy to comprehend arguments; whereas, there was a correlation only between attitude and favourable thoughts 11 toward the issue with difficult to comprehend arguments, suggesting, perhaps, that central route processing, \vhich involves argument scrutiny and elaboration, occurred under conditions of easy comprehension to a greater extent than under conditions of difficult comprehension. The results also revealed, among other findings, several significant effects of gender. Men had more favourable attitudes toward the legal issue than did women, men recalled more arguments from the speech than did women, men were less frustrated while listening to the speech than were ,vomen, and men put more effort into thinking about the message arguments than did women. When the arguments were difficult to comprehend, men had more favourable thoughts and fewer unfavourable thoughts about the legal issue than did women. Men and women may have had different affective responses to the issue of plea bargaining (with women responding more negatively than men), especially in light of a local and controversial plea bargain that occurred around the time of this study. Such pre-existing gender differences may have led to tIle lower frustration, the greater effort, the greater recall, and more positive attitudes for men than for WOlnen. Results· from this study suggest that current cognitive models of persuasion may not be very applicable to controversial issues which elicit strong emotional responses. Finally, these data indicate that affective responses, the controversial and emotional nature ofthe issue, gender and other individual differences are important considerations when experts are attempting to persuade laypeople toward a counterattitudinal position.

The road not taken: observing a process of issue selection and model conceptualization

This article describes a case study involving information technology managers and their new programmer recruitment policy, but the primary interest is methodological. The processes of issue generation and selection and model conceptualization are described. Early use of “magnetic hexagons” allowed the generation of a range of issues, most of which would not have emerged if system dynamics elicitation techniques had been employed. With the selection of a specific issue, flow diagraming was used to conceptualize a model, computer implementation and scenario generation following naturally. Observations are made on the processes of system dynamics modeling, particularly on the need to employ general techniques of knowledge elicitation in the early stages of interventions. It is proposed that flexible approaches should be used to generate, select, and study the issues, since these reduce any biasing of the elicitation toward system dynamics problems and also allow the participants to take up the most appropriate problem- structuring approach.

A model of private bank-note issue

A random-matching model (ofmoney) is formulated in which there is complete public knowledge of the trading histories of a subset of the population, called the banking sector, and no public knowledge of the trading histories of the complement of that subset, called the non bank sector. Each person, whether a banker or a non banker, is assumed to have the technological capability to create indivisible and durable objects called notes. If outside money is indivisible and sufficiently scarce, then the optimal mechanism is shown to have note issue and note destruction (redemption) by members of the banking sector.
