Selecting the individual numerical scale and prioritization method in the analytic hierarchy process : a 2-tuple fuzzy linguistic approach

The validity of the priority vector used in the analytic hierarchy process (AHP) relies on two factors: the selection of a numerical scale and the selection of a prioritization method. The traditional AHP selects only one numerical scale (e.g., the Saaty scale) and one prioritization method (e.g., the eigenvector method) for each particular problem. For this traditional selection approach, there is disagreement on which numerical scale and prioritization method is better in deriving a priority vector. In fact, the best numerical scale and the best prioritization method both rely on the content of the pairwise comparison data provided by the AHP decision makers. By defining a set of concepts regarding the scale function and the linguistic pairwise comparison matrices (LPCMs) of the priority vector and by using LPCMs to unify the format of the input and output of AHP, this paper extends the AHP prioritization process under the 2-tuple fuzzy linguistic model. Based on the extended AHP prioritization process, we present two performance measure criteria to evaluate the effect of the numerical scales and prioritization methods. We also use the performance measure criteria to develop a 2-tuple fuzzy linguistic multicriteria approach to select the best numerical scales and the best prioritization methods for different LPCMs. In this paper, we call this type of selection the individual selection of the numerical scale and prioritization method. We also compare this individual selection with traditional selection by using both random and real data and show better results with individual selection.

Wavelets/multiwavelets bases and correspondence estimation problem : an analytic study

Correspondence estimation in one of the most active research areas in the field of computer vision and number of techniques has been proposed, possessing both advantages and shortcomings. Among the techniques reported, multiresolution analysis based stereo correspondence estimation has gained lot of research focus in recent years. Although, the most widely employed medium for multiresolution analysis is wavelets and multiwavelets bases, however, relatively little work has been reported in this context. In this work we have tried to address some of the issues regarding the work done in this domain and the inherited shortcomings. In the light of these shortcomings, we propose a new technique to overcome some of the flaws that could have significantly impact on the algorithm performance and has not been addressed in the earlier propositions. Proposed algorithm uses multiresolution analysis enforced with wavelets/multiwavelts transform modulus maxima to establish correspondences between the stereo pair of images. Variety of wavelets and multiwavelets bases, possessing distinct properties such as orthogonality, approximation order, short support and shape are employed to analyse their effect on the performance of correspondence estimation. The idea is to provide knowledge base to understand and establish relationships between wavelets and multiwavelets properties and their effect on the quality of stereo correspondence estimation.

Analytic solution for the three-layer multiple beam interferometer

We present a simple analytic solution for the condition of constructive interference for light transmitted through an interferometer incorporating three ideally transparent layers of arbitrary thickness and refractive index. We also consider the effect of adding two metallic coatings to the outer surfaces of the interferometer and give empirical expressions for the associated phase changes for silver coatings on silica, sapphire, and mica substrates. A particular application to fringes of equal chromatic order can be utilized to obtain precise measurements of the thickness of extremely thin films sandwiched between two substrates.

Deleuze : 'Had I not done philosophy I would have done law'

For those too few of us who carry a flame for an idea or shape of community and if necessary law to come Deleuze provides us with some useful signposts and overall a working toolbox with which to tackle both the micro and macro of our daily encounters. The whole package of Deleuzian machines and assemblages can be taken up as an abstract discourse which too outsiders might appear devoid of any linkage to reality. The whole notion of Deleuzian lawyers is one that can easily raise a chuckle, but nevertheless some of us seem to persevere with playing with the law with this toolbox.

Analytic study on pure bending of metal sheets

In this work, analytical models of pure bending are developed to simulate a particular type of bend test and to determine possible errors arising from approximations used in analyzing experimental data. Analytical models proposed for steels include a theoretical solution of pure bending and a series of finite element models, based on the von Mises yield function, are subjected to different stress and strain conditions. The results show that for steel sheets the difference between measured and calculated results of the moment-curvature behaviour is small and the numerical results from the finite element models indicate that experimental results obtained from the test are acceptable in the range of the pure bending operation. Further for magnesium alloys, which exhibit unsymmetrical yielding, the algorithm of the yield function with a linear isotropic hardening model is implemented by programming a user subroutine in Abaqus for bending simulations of magnesium. The simulations using the proposed user subroutine extract better results than those using the von Mises yield function.

Meta-analytic review of neurocognition in bipolar II disorder

Objective: The clinical distinction between bipolar II disorder (BD II) and bipolar I disorder (BD I) is not clear-cut. Cognitive functioning offers the potential to explore objective markers to help delineate this boundary. To examine this issue, we conducted a quantitative review of the cognitive profile of clinically stable patients with BD II in comparison with both patients with BD I and healthy controls.
Method: Meta-analytical methods were used to compare cognitive functioning of BD II disorder with both BD I disorder and healthy controls.
Results: Individuals with BD II were less impaired than those with BD I on verbal memory. There were also small but significant difference in
visual memory and semantic fluency. There were no significant differences in global cognition or in other cognitive domains. Patients with BD II performed poorer than controls in all cognitive domains.
Conclusion: Our findings suggest that with the exception of memory and semantic fluency, cognitive impairment in BD II is as severe as in BD I. Further studies are needed to investigate whether more severe deficits in BD I are related to neurotoxic effects of severe manic episodes on medial temporal structures or neurobiological differences from the onset of the illness.

Philosophy and the view from above in Alejandro's Amenabar's agora

 This paper examines the depiction of neoplatonic philosopher, geometer and astronomer Hypatia in Alejandro Amenabar's 2010 fil Agora.  The paper uses Pierre Hadot's work, and his arguments that ancient philosophy was conceived as a way of life, aiming at the ideal existence of the sage, and characterised by spiritual exercises.  The paper argues that Amenabar's film employs the technique of the view from above, one such spiritual exercise, wherein the agent relooks at his or life sub spaecie aeternitatis or 'from above', to frame Hypatia's life and death, and the end of the pagan epoch in Alexandria.

Philosophy has consequences! Developing metacognition and active learning in the ethics classroom

The importance of enchancing metacognition and encouraging active learning in philosophy teaching has been increasingly recognised in recent years. Yet traditional teaching methods have not always centralised helping students to become reflectively and critically aware of the quality and consistency of their own thinking. This is particularly relevant when teaching moral philosophy, where apparently inconsistent intuitions and responses are common. In this paper I discuss the theoretical basis of the relevance of metacognition and active learning for teaching moral philosophy. Applying recent discussions of metacognition, intuition conflicts and survey-based teaching techniques, I then outline a strategy for encouraging metacognitive awareness of tensions in students’ pretheoretical beliefs, and developing a critical self-awareness of their development as moral thinkers.

Is narrative identity four-dimensionalist?

The claim that selves are narratively constituted has attained considerable currency in both analytic and continental philosophy. However, a set of increasingly standard objections to narrative identity are also emerging. In this paper, I focus on metaphysically realist versions of narrative identity theory, showing how they both build on and differ from their neo-Lockean counterparts. But I also argue that narrative realism is implicitly committed to a four-dimensionalist, temporal-parts ontology of persons. That exposes narrative realism to the charge that the narratively constituted self, on the one hand, and the self that is the object of much of our everyday self-reference and self-experience, on the other, can’t be the same thing. This conclusion may well force narrativists to abandon metaphysical realism about narrative selves — which, in turn, may leave the invocation of ‘narrativity’ as identity-constituting somewhat under-motivated.

Towards a transpersonal psychology of Daoism

Daoism (Taoism) is a collection of Chinese philosophical beliefs and psychospiritual practices with a history of thousands of years, and a living community that stretches throughout East Asia. I will argue that Daoism and its corresponding texts such as those included in the Daozang provide a wealth of material regarding trans-egoic experiences (e.g., unitive absorption in the Dao), that may enhance Western psychologists’ understanding of transpersonal phenomena. Curiously, however, despite the obvious points of intersection between Daoism and transpersonal psychology (e.g., a mutual interest in phenomena typically referred to as altered states of consciousness), to date transpersonal psychologists have neglected to investigate Daoism. Indeed, the majority of published research concerning the relationships between Daoism and Western psychology has been undertaken from within the Jungian analytic and humanistic psychological movements. After reviewing this literature, I will formulate various proposals for future empirical studies that may interest transpersonal psychologists.
