Institutional consequentialism and global governance

Elsewhere we have responded to the so-called demandingness objection to consequentialism – that consequentialism is excessively demanding and is therefore unacceptable as a moral theory – by introducing the theoretical position we call institutional consequentialism. This is a consequentialist view that, however, requires institutional systems, and not individuals, to follow the consequentialist principle. In this paper, we first introduce and explain the theory of institutional consequentialism and the main reasons that support it. In the remainder of the paper, we turn to the global dimension where the first and foremost challenge is to explain how institutional consequentialism can deal with unsolved global problems, such as poverty, war and climate change. In response, following the general idea of institutional consequentialism, we draw up three alternative routes: relying on existing national, transnational and supranational institutions; promoting gradual institutional reform; and advocating radical changes to the status quo. We evaluate these routes by describing normatively relevant properties of the existing global institutional system, as well as by showing what institutional consequentialism can say about alternatives to it: a world government; and multi-layered sovereignty/neo-medieval system.     

Political Economy of Conflict and Conflict Resolution Between Islam,the Arab World,and the West

The problem studied in respect to politico-economic turmoil in an uneasy world centers around conflicts in the Arab world and between Islam and the West. In this respect, the Arab political economy is deeply embroiled in a quagmire of complex factors that have deepened and are confounded by Western political, strategic, and economic interests in the region. To study the topic of the politico-economic future of the Arab world is to delve into the study of complex factors. The present scenario of war, dissensions, power conflict, and Western belligerence with elitist self interest in the region is an example of a more permanent representation of the complexity of power, Western belligerence, regional interests, and religious conflicts. With respect to the political economy of conflict and conflict resolution concerning the West there is the uneasy alliance that has been unjustifiably established between the Arab world and the West. The conflict in this case rages around the spectre of political power and governance within which the cultural, religious, and economic forces tie in to generate the global political economic disorder. Conflict resolution in this arena requires an understanding based on acceptance of epistemological perspectives that wrap up the diverse oppositional factors into a discursive and consensual learning global social contract. This article studies this case of Arab political economy as a study of conflict and conflict resolution between contending forces and reconstructive politico-economic possibilities between the Arab world and the West and between Islam, the Arab world, and Occidentalism.     

Individual ambidexterity: the duality of exploration and exploitation and its relationship with innovative performance

Organizational ambidexterity has been established as an important antecedent of organizational innovation and performance. Recently, researchers have started to argue that ambidexterity is not only essential at the organizational, but also at the individual level. Thus, to be innovative, individuals need to engage in both explorative and exploitative behaviours. However, questions remain regarding the optimal balance of explorative and exploitative behaviours and how ambidexterity can be operationalized. At the organizational level, most empirical research utilized either the difference between, or the product of, exploration and exploitation. In this article, we criticize these approaches on conceptual and methodological grounds and argue for an alternative operationalization of ambidexterity: polynomial regression and response surface methodology. In two diary studies with daily and weekly data, we demonstrate the advantages of this approach. We discuss implications for ambidexterity research and innovation practice.     

The regression trunk approach to discover treatment covariate interaction

The regression trunk approach (RTA) is an integration of regression trees and multiple linear regression analysis. In this paper RTA is used to discover treatment covariate interactions, in the regression of one continuous variable on a treatment variable withmultiple covariates. The performance of RTA is compared to the classical method of forward stepwise regression. The results of two simulation studies, in which the true interactions are modeled as threshold interactions, show that RTA detects the interactions in a higher number of cases (82.3% in the first simulation study, and 52.3% in the second) than stepwise regression (56.5% and 20.5%). In a real data example the final RTA model has a higher cross-validated variance-accounted-for (29.8%) than the stepwise regression model (12.5%). All of these results indicate that RTA is a promising alternative method for demonstrating differential effectiveness of treatments.

An experimentally confirmed statistical model on arm movement

The purpose of this research work was to develop a methodology to model arm movement in normal subjects and neurologically impaired individuals through the application of a statistical modelling method. Thirteen subjects with Parkinson's disease and 29 normal controls were recruited to participate in an arm motor task. An infrared optoelectronic kinematic movement analysis system was employed to record arm movement at 50 times per second. This study identified the modified extended Freundlich model as one that could be used to describe this task. Results showed that this model fit the data well and that it has a good correspondence between the observed and the predicted data. However, verification of the model showed that the residuals contained a sizeable autocorrelation factor. The Cochrane and Orcutt method was applied to remove this factor, which improved the fit of the model. Results showed that Parkinson's disease subjects had a higher autocorrelation coefficient than the normal subjects for this task. A positive correlation (r(s) = 0.72, p < 0.001) was found between the Langton-Hewer stage and the autocorrelation coefficient of PD subjects. This finding suggests that if autocorrelation is positively correlated with disease progression, clinicians in their clinical practice might use the autocorrelation value as a useful indicator to quantify the progression of a subjects' disease. Significant differences in model parameters were seen between normal and Parkinson's disease subjects. The use of such a model to represent and quantify movement patterns provides an important base for future study.     

Developmental changes in the processing of hierarchical shapes continue into adolescence

The present study was designed to trace the normal development of local and global processing of hierarchical visual forms. We presented pairs of hierarchical shapes to children and adults and asked them to indicate whether the two shapes were the same or different at either the global or the local level. In Experiments 1 (6-year-olds, 10-year-olds, adults) and 2 (10-year-olds, 14-year-olds, adults), we presented stimuli centrally. All age groups responded faster on global trials than local trials (global precedence effect), but the bias was stronger in children and diminished to the adult level between 10 and 14 years of age. In Experiment 3 (10-year-olds, 14-year-olds, adults), we presented stimuli in the left or right visual field so that they were transmitted first to the contralateral hemisphere. All age groups responded faster on local trials when stimuli were presented in the right visual field (left hemisphere); reaction times on global trials were independent of visual field. The results of Experiment 3 suggest that by 10 years of age the hemispheres have adult-like specialization for the processing of hierarchical shapes, at least when attention is directed to the global versus local level. Nevertheless, their greater bias in Experiments 1 and 2 suggests that 10-year-olds are less able than adults to modulate attention to the output from local versus global channels-perhaps because they are less able to ignore distractors and perhaps because the cerebral hemispheres are less able to engage in parallel processing.     

Soviet Philosophy Revisited – Why Joseph Bocheński Was Right While Being Wrong

Josef Bocheski, pioneer of the discipline ofphilosophical sovietology and one of the firstto criticize Eurocentric attitudes, emphasizedthe central role of logic and sound argument inacademic philosophy. This helped him todemonstrate both the general flaws of and thedifferences in quality within Sovietphilosophy. His endeavors and results areindispensable for the yet-to-be-written historyof Soviet philosophy. By the same token, itmade him less perceptive of the centralpolitical, not just philosophical, role of thepartijnost'-principle. More recent developmentshave shown both Soviet philosophy andBocheski's own, Neo-Thomist position to bepart of a fundamentally outdated idea ofscientific philosophy. However, the criteria oflogical scrutiny and sound argument have notlost their force within globalizingphilosophical culture.     

Global challenges as inspiration: A classroom strategy to foster social responsibility

Social responsibility is at the heart of the Engineer’s Creed embodied in the pledge that we will “dedicate [our] professional knowledge and skill to the advancement and betterment of human welfare...[placing] public welfare above all other considerations.” However, half century after the original creed was written, we find ourselves in a world with great technological advances and great global-scale technologically-enabled peril. These issues can be naturally integrated into the engineering curriculum in a way that enhances the development of the technological skill set. We have found that these global challenges create a natural opportunity to foster social responsibility within the engineering students whom we educate. In freshman through senior-level materials engineering courses, we used five guiding principles to shape several different classroom activities and assignments. Upon testing an initial cohort of 28 students had classroom experiences based on these five principles, we saw a shift in attitude: before the experience, 18% of the cohort viewed engineers as playing an active role in solving global problems; after the experiences, 79% recognized the engineer’s role in solving global-scale problems. In this paper, we present how global issues can be used to stimulate thinking for socially-responsible engineering solutions. We set forth five guiding principles that can foster the mindset for socially responsible actions along with examples of how these principles translate into classroom activities. An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005.

The modality shift effect and the effectiveness of warning signals in different modalities

Which is better, a visual or an auditory warning signal? Initial findings suggested that an auditory signal was more effective, speeding reaction to a target more than a visual warning signal, particularly at brief foreperiods [Bertelson, P., & Tisseyre, F. (1969). The time-course of preparation: confirmatory results with visual and auditory warning signals. Acta Psychologica, 30. In W.G. Koster (Ed.), Attention and Performance II (pp. 145-154); Davis, R., & Green, F. A. (1969). Intersensory differences in the effect of warning signals on reaction time. Acta Psychologica, 30. In W.G. Koster (Ed.), Attention and Performance II (pp. 155-167)]. This led to the hypothesis that an auditory signal is more alerting than a visual warning signal [Sanders, A. F. (1975). The foreperiod effect revisited. Quarterly Journal of Experimental Psychology, 27, 591-598; Posner, M. I., Nissen, M. J., & Klein, R. M. (1976). Visual dominance: an information-processing account of its origins and significance. Psychological Review, 83, 157-171]. Recently [Turatto, M., Benso, F., Galfano, G., & Umilta, C. (2002). Nonspatial attentional shifts between audition and vision. Journal of Experimental Psychology: Human Perception and Performance, 28, 628-639] found no evidence for an auditory warning signal advantage and showed that at brief foreperiods a signal in the same modality as the target facilitated responding more than a signal in a different modality. They accounted for this result in terms of the modality shift effect, with the signal exogenously recruiting attention to its modality, and thereby facilitating responding to targets arriving in the modality to which attention had been recruited. The present study conducted six experiments to understand the cause of these conflicting findings. The results suggest that an auditory warning signal is not more effective than a visual warning signal. Previous reports of an auditory superiority appear to have been caused by using different locations for the visual warning signal and visual target, resulting in the target arriving at an unattended location when the foreperiod was brief. Turatto et al.'s results were replicated with a modality shift effect at brief foreperiods. However, it is also suggested that previous measures of the modality shift effect may still have been confounded by a location cuing effect.
