Varela and Contemporary Psychoanalysis,an Epistemological Gesture: From Representations to Co-emergence

This paper intends to articulate common epistemological elements between Francisco Varela’s and Contemporary psychoanalytic relational-intersubjective theories. These shared elements could be described as a common epistemological gesture, the overcome of a reductionist and dualist paradigm, instead giving away to a paradigm of complexity. In both perspectives, a phenomenological and close to experience philosophical reflection is incorporated, which can account the human experience as an irreducible and valid source of knowledge. In Varela’s theory, the notion of embodiment permit to conceive the mind as natural endowment of the body. In Contemporary psychoanalytic theories, nature of human experience is conceive as intrisically social, proposing a “two person” psychology and the intersubjective model. Finally, in line with both currents and in a preliminary way, I propose the notion of co-emergency, seeking to overcome different forms of dualisms like internal/external, subject/world, I/Other, etc. From a clinical perspective, co-emergency can be conceived a s the coupling of two subjectivities, as a particular experiential mode of being with others, intending to overcome dualism regarding transference and represented mental states.     

Estimation in High-Dimensional Analysis and Multivariate Linear Models

This article presents a new approach of estimating the parameters describing the mean structure in the Growth Curve model when the number of variables compared with the number of observations is large. An unbiased, consistent, and asymptotic normal estimator is derived as well as its.     

Racialisation and racial formation in urban spaces*

ABSTRACT

In this paper, I try to clarify the notions of racialisation and racial formation and how they operate in the framework of nation states like Brazil. My main argument is that these processes are always constrained by the formation of social classes and national cultural repertoires even if transnational forces are important in nurturing them. I conclude by making a preliminary effort to unravel mechanisms and institutions which allow these processes of racialisation and racial formation to form part of the daily lives of black Brazilians in the context of class-structured urban spaces.     

Involvement of advanced glycation end products in the pathogenesis of diabetic complications: the protective role of regular physical activity

Advanced glycation end products (AGEs) may play an important role in the pathogenesis of chronic diabetic complications and in the natural process of biological aging. In fact, maintained hyperglycaemia favours the formation of AGEs at the tissue level in diabetic patients, which may influence the triggering of different chronic pathologies of diabetes such as retinopathy, nephropathy, neuropathy and macro- and micro-vascular diseases. Moreover, the literature has also demonstrated the involvement of AGEs in biological aging, which may explain the accelerated process of aging in diabetic patients. The practice of regular physical activity appears to positively influence glycaemic control, particularly in type 2 diabetes mellitus patients. This occurs through the diminution of fasting glycaemia, with a consequent reduction of glycation of plasmatic components suggested by the normalisation of HbA1c plasmatic levels. This exercise-induced positive effect is evident in the blood of diabetic patients and may also reach the endothelium and connective tissues of different organs, such as the kidneys and eyes, and systems, such as the cardiovascular and nervous systems, with a local reduction of AGEs production and further deceleration of organ dysfunction. The aim of this paper was to review the literature concerning this topic to coherently describe the harmful effects of AGEs in organ dysfunction induced by diabetes in advanced age as well as the mechanisms behind the apparent protection given by the practice of regular physical activity.     

Lean-healthcare approach to reduce costs in a sterilization plant based on surgical tray rationalization

Abstract

Sterilization plants process all reusable materials used in hospitals during different stages of healthcare provision. Most items sterilized come from the surgical theater in the form of individual instruments, linen and surgical trays. Reducing the number of instruments in trays impacts on the performance of the sterilization process. Here, we propose a three-phase method, based on lean healthcare principles, cluster analysis and kaizen groups of experts to rationalize surgical trays, reducing sterilization processing costs. We innovate by proposing a strategy to approach tray rationalization prioritizing surgical specialties that are both complex and frequent, and by using group technology to cluster surgical trays expediting expert analyses carried out by kaizen groups. Our propositions were tested in a high complexity, tertiary care hospital, covering 12 surgical specialties, reducing the number of instruments by average 9.75%, and the time-to-assemble trays by average 9.68%, obtaining annual savings of US$285.756,00 in sterilization processing costs.     

A maximal domain of preferences for strategy-proof,efficient, and simple rules in the division problem

The division problem consists of allocating an amount M of a perfectly divisible good among a group of n agents. Sprumont (1991) showed that if agents have single-peaked preferences over their shares, the uniform rule is the unique strategy-proof, efficient, and anonymous rule. Ching and Serizawa (1998) extended this result by showing that the set of single-plateaued preferences is the largest domain, for all possible values of M, admitting a rule (the extended uniform rule) satisfying strategy-proofness, efficiency and symmetry. We identify, for each M and n, a maximal domain of preferences under which the extended uniform rule also satisfies the properties of strategy-proofness, efficiency, tops-onlyness, and continuity. These domains (called partially single-plateaued) are strictly larger than the set of single-plateaued preferences. However, their intersection, when M varies from zero to infinity, coincides with the set of single-plateaued preferences.An earlier version of this paper circulated under the title A maximal domain of preferences for tops-only rules in the division problem. We are grateful to an associate editor of this journal for comments that helped to improve the presentation of the paper and to Matt Jackson for suggesting us the interest of identifying a maximal domain of preferences for tops-only rules.

Extending an order to the power set: The Leximax Criterion

This work analyzes the issue of ranking the levels of well-being enjoyed by an agent when dealing with her opportunity set in a freedom of choice context. We try to propose a natural extension of a preference relation over a (possibly) infinite set X to its power set, compatible with the finite Leximax criterion.

Information and communication technologies and migrant intimacies: the case of Punjabi youth in Manila

This article examines how South–South migrants use information and communication technologies (ICTs) in negotiating their encounters with traditional cultural imaginaries of intimacy. It focuses on second-generation Punjabi Indian youth in the Philippine capital of Manila. Through an ethnographic approach, it unpacks how these migrants harness technologies to steer through two particular ideals about the end-goal of intimate relationships: the Punjabi notion of arranged marriage and the Filipino notion of love marriage. I characterise how the young Punjabis use ICTs to enact what I call a ‘temporarily resolution’ to their migrant double consciousness about intimacy. I also describe how this temporary resolution continues to be entwined with the wider dynamics of multicultural relations in the Philippines. Ultimately, I aim to better understand the role of ICTs in migrant intimacies, especially within the realities of multiculturalism in a postcolonial city in the Global South.     

Housing Valuation,Wealth Perception,and Homeowners’ Portfolio Composition

This study explores the link between wealth perception from an appreciation of the residential property price and homeowners’ preference toward asset categories pooled by risk. Household survey data for Portugal were used to build shares of low, medium, and high risk assets representing fractions of household’s total wealth. Data showed incomplete household portfolios along with housing capturing the largest share of households’ wealth, in line with the literature on composition puzzles. The findings indicate robust empirical evidence that the rate of housing valuation is an indicator of households’ wealth perception. When the housing price appreciates with respect to its initial cost, households suffer an endowment effect and tend to increase diversity in their portfolio, expanding the holdings of safe deposits as they raise the share of high risk assets.
