Rabbit meat in the east of Algeria: motivation and obstacles to consumption
Authors: Sanah Ibtissem , Becila Samira , Djeghim Fairouz , Boudjellal Abdelghani
Published: December 2020

In Algeria, rabbit meat consumption is insufficiently anchored in culinary traditions compared to other types of meat that are widely consumed, namely sheep and chicken. The purpose of this research is to investigate the influence of sociogeographic variables, both intrinsic and extrinsic quality cues, on consumption frequency, purchasing decision, motivations and the main deterrents to rabbit meat consumption. A survey is conducted with 360 consumers across 15 wilayas (districts) in Eastern Algeria. The results help us draw a conclusion that rabbit meat is consumed in all surveyed wilayas with a low frequency of consumption for the majority of respondents (79%). On the one hand, the causes of consumption are mainly: good taste (59%) and nutritional value (27%). On the other hand, the limiting factors are different: scarcity of rabbit meat on the market (42%), price (22%), eating habits (17%), lack of information on nutritional value (13%), bad taste (3%) and its resemblance to cat meat (3%). Regarding purchasing criteria, tenderness (58%) and freshness (14%) were chosen by most consumers. Although most consumers recognise the nutritional benefits of rabbit meat, it is poorly ranked in the choice of its consumers, placing it fourth after sheep, beef and poultry. Cross tabulation results show that gender, employment status and geographical areas are three variables that significantly affect the consumer’s perception and behaviour towards rabbit meat. This study is the first to analyse the Algerian consumer profile and sheds light on factors encouraging and hindering rabbit meat consumption.

Published: December 2020

This study was carried out to assess the effect of dietary levels of zinc on semen indices, growth parameters and testicular sperm reserve of heterogeneous stock of male rabbits. Twenty male rabbits aged 6 mo old were randomly allotted to four groups of five males each and fed diets containing 0, 50, 100 and 150 mg of zinc gluconate per kg diet, respectively, for eight weeks. Semen was collected from the males weekly using an artificial vagina and semen volume (mL), spermatozoa motility (%), sperm concentration (×108/mL) and live sperm cells (%) were assessed. Seminal plasma was separated from the semen by centrifugation, and its zinc concentration was determined using atomic absorption spectrometry. The weights of the males were taken weekly, and the daily feed intake was recorded. At the end of the feeding trial, the rabbits were stunned and slaughtered; the testes and epididymis were carefully removed and homogenised to determine sperm reserves using standard procedure. The result showed that semen indices were not significantly influenced by the dietary levels of zinc gluconate. Seminal zinc concentration was significantly higher in males fed 100 and 150 mg of zinc per kg compared to those in the control group. A higher body weight gain (454±50.3 g), testes weight (6.23±0.25 g) and epididymis weight (1.63±0.59 g) was recorded in males fed diet supplemented with 50 mg of Zinc gluconate per kg. No significant effect of dietary zinc supplementation was recorded in testicular sperm reserve. Epididymal sperm reserve was significantly higher in males fed the diets including 100 and 150 mg of zinc gluconate per kg. In conclusion, dietary levels of zinc gluconate did not improve semen quality and growth indices but increased seminal zinc concentration, which could result in improved prostate health in the heterogeneous stock of male rabbits in the tropics.

Published: December 2020

The aim of the study was to learn about the structure of broiler rabbit skins, with the possibility of using them as dressing for gloves and shoe uppers. The histological structure, organoleptic and rheological properties of leathers such as tensile and puncture strength, energy state based on dynamic tests and topography map of their thickness were assessed. The study material included the skins of two groups of hybrid rabbits (F1), 24 pieces each, from breeds crossing: ♂ Belgian Giant Grey × ♀ Burgundy (BOS×BU), or ♂ Belgian Giant Grey × ♀ New Zealand White (BOS×BNZ). Histological, rheological, organoleptic and topography thickness studies of broiler rabbit leathers have proven that they can be intended for the production of not only gloves, but also shoe uppers. The leathers of BOS x BU hybrid proved to be a better raw material than BOS x BNZ for the production of both gloves and footwear.
The Great Lockdown

Published: December 2020

Voluntary and government-mandated lockdowns in response to COVID-19 have caused causing drastic reductions in economic activity around the world. We present a parsimonious two-country-SIR model with some degree of substitutability between home and foreign goods, and show that trading partners’ asynchronous entries into the global pandemic induce mutual welfare gains from trade. Those gains are realized through exchange rate adjustments that cause a temporary reallocation of production towards the economy with the lowest infection rate at any point in time. We show that international cooperation over containment policies that aim at optimizing global welfare further enhances the ability of countries to exploit trade opportunities to contain the spread of the pandemic. We characterize the Nash game of strategic choices of containment policies as a prisoners’ dilemma.

Published: December 2020

Recent financial crises including the ongoing one caused by the COVID-19 pandemic have consistently drawn attention to the need to strengthen the quality of public debt management in emerging markets and developing countries. Deeper and more efficient domestic government debt markets—being, a key segment of the LCBM for many emerging markets and developing economies—play a key role in reducing financial vulnerability to shocks and enable governments to finance critical economic and fiscal policy measures in response to them. Policymakers and international organizations have long recognized that developing and strengthening LCBMs is a key policy prescription to sound public debt management. Robust legal and regulatory frameworks are recognized as being critical building blocks for the structure, development and functioning of LCBMs. This Working Paper seeks to outline a strategically anchored methodology that can be applied to design, build and implement the legal and tax foundations for the development of LCBMs that would adequately address common challenges and impediments.

Published: December 2020

The COVID-19 pandemic has worsened Brazil’s longstanding vulnerabilities of low potential growth, high income inequality, and weak fiscal position. While the authorities mounted a rapid and effective response to support the economy and protect the poor and vulnerable, the virus outbreak is yet to be brought under control.
Outlook and Risks. Real GDP is projected to contract by 5.8 percent in 2020 followed by a partial recovery to 2.8 percent in 2021. With weak domestic demand, inflation is likely to end 2020 substantially below target. Debt is projected to jump to 100 percent of GDP, due to a 10.6 percentage point deterioration in the primary deficit in 2020, and continue to rise over the next five years. The high level of debt exposes Brazil to confidence shocks. Securing congressional passage of structural reforms to raise potential growth remains challenging.

Published: December 2020

The article describes methods for spherical visualizing of data as global geophysical, environmental, atmospheric processes on the surface of planets and different kinds of processes on the surface of spherical bodies. Such data can be demonstrated through virtual globes and spherical screens. Volumetric visualization significantly increases the degree of visibility, comprehension and assimilation of the demonstrated content and may be used in the scientific and educational process. The main goal of this research is to develop database requirements for spherical visualization. The requirements are based on the modern educational and science research representation approaches. The following tasks have been formed and accomplished: a strict classification of data; a convenient way to interact at the stage of adding data to the database and analyzing; their representativeness; introduction of additional data classifications; the possibility of individual user navigation and a high degree of inter-activity. For the proposed model, the basic functions of the database management system are described. Requirements to a basic hierarchical data model were substantiated. The main object of hierarchical data model is a spherical Slide representing a separate topic of particular discipline. The superstructure is used above the hierarchical model in the form of an individual route map representing a directory with links to the main database.
Methods Calculating the Slab Radiance Factor
Authors: Budak Vladimir , Efremenko Dmitry
Published: December 2020

One of the most critical problems of realistic visualization of the real-world objects is physically adequate modeling of their reflection of light. Reflection of light by objects occurs both from the surface and the bulk of matter (scattering). Accounting for the light reflection from the surface of objects was solved almost a century ago based on its representation as a Fresnel randomly rough surface. Scattering by a bulk of matter is the subject of radiation transfer theory, which has only recently received its known completion in the form of discrete transfer theory. Strict analytical methods for solving the radiation transport equation (RTE) are often not highly effective for calculating the radiance factor. For a long time, in the absence of effective numerical methods for solving problems and the unavailability of high-speed computers for practical calculations, approximate methods for solving RTE were developed. However, their accuracy and applicability limits were poorly defined. The discrete transfer theory allowed us to evaluate the existing approximate methods for solving the UPI, their accuracy, and the efficiency of application for calculating the radiance factor. It is shown that the most effective method is the method of synthetic iterations. The method is based on the selection of the solution anisotropic part based on a small-angle approximation of the RTE solution. The solution regular part can be calculated by any approximation. Then a simple iteration from the complete solution is performed to refine the angular distribution of the radiance factor.

Published: December 2020

Application of the Internet-connected operational devices in the heating, ventilation and conditioning (HVAC) systems has extended the cyber-attack surface by introducing different malicious scenarios. The analysis of the HVAC data may provide insight on typical patterns of the system operations. Implementation of the thoroughly elaborated visualization models may significantly increase the efficiency of the suspicious activity identification in the HVAC systems. In the paper we present the results of the laboratory usability testing of three visualization models used to analyze HVAC data – matrix-based visualization technique, non-linear multidimensional visualization technique RadViz and timeline chart. Matrix-based visualization and RadViz visualization are often used in anomaly detection process, while timeline charts are a traditional way to present operational HVAC data. We describe the experiment design and discuss the results obtained. The usability testing revealed advantages and limitations of these visualization techniques in behavior pattern and anomaly identification tasks. The results can further serve as guidelines for task-dependent selection of a visualization technique.

Authors: Andreev Sergey , Bondarev Alexander , Bondarenko Alexander , Galaktionov Vladimir , Bondareva Nicole
Published: December 2020

The tasks of constructing stereo representations of texts and formulas on an autostereoscopic monitor in stereo presentations designed to display the results of numerical modeling are an urgent sub-task in developing methods and algorithms for constructing stereo displays of scientific research results. In this paper, the construction of stereo images on an autostereoscopic monitor is considered. The autostereoscopic monitor allows you to watch stereo images without glasses, while ensuring the quality of the stereo image, which is not inferior to the quality of the stereo image presented using the classic 3D projection stereo system. The possibility of combining several stereo objects with different parameters on one frame with various parameters allowing to achieve the maximum stereo effect is being investigated. This technology has been applied practically to visualize the problems of verification of numerical methods and their comparative analysis. Similar solutions for the two-parameter problem are represented in the form of error surfaces constructed for each numerical method involved in the comparison. The construction of error surfaces in stereo mode is implemented for an autostereoscopic monitor based on a multi-view.

Published: December 2020

Fiducial markers are used in vision systems to determine the position of objects in space, reconstruct movement and create augmented reality. Despite the abundance of work on analysis of the accuracy of the estimation of the fiducial markers spatial position, this question remains open. In this paper, we propose the computer modeling of images with ArUco markers for this purpose. The paper presents a modeling algorithm, which was implemented in the form of software based on the OpenCV library. Algorithm is based on projection of three-dimensional points of the marker corners into two-dimensional points using the camera parameters and rendering the marker image in the new two-dimensional coordinates on the modeled image with the use of the perspective transformation obtained from these points. A number of dependencies were obtained by which it is possible to evaluate the error in determining the position depending on markers size. Including the probability of detecting a marker depending on its area on an image.

Published: December 2020

In-flight measurements are one of the directions of aircraft testing which has been developed actively recently. Creation of a flight laboratory based on an unmanned vehicle to reduce the cost of developing and analysis techniques for in-flight measurements is proposed. For the laboratory an onboard system for recording experimental images during a flight was developed. It was decided to conduct computer modeling of images that can be obtained using the developed system for its verification. Unity a cross-platform photorealistic graphic engine with visual integrated development environment was chosen for this purpose. For modeling both external and internal real camera parameters, including distortion coefficients, and parameters of the measured surface could be preassigned. The developed methodology for computer modeling of images of the deformable surface allows to evaluate the accuracy of various algorithms for processing experimental images, as well as the influence of the parameters of the experimental setup on the error of the measurements results.
Revisiting Second Wave Feminism in the Light of Recent Controversies
Authors: Power Nina
Published: December 2020

This paper revisits elements of second wave feminism—in its psychoanalytic, radical, materialist, Marxist and deconstructionist aspects—the better to understand how it is we might define sexual difference today. The vexed question of sexuation, of what it means to be a woman in particular has today generated great tensions at the theoretical, legal and philosophical level. This paper is an attempt to return to aspects of the second wave—an unfinished project where many enduring feminist concerns were for the first time thoroughly and metaphysically articulated—the better to defend the importance of sexual difference. To this end, the transcendental and parallax dimensions of sexed life will be discussed, alongside a defence of the centrality of the mother to our thinking about the relevance and necessity of preserving the importance of sexual difference, not only for thought but also for political and legal life.

Deterministische, dynamische Systemstrukturen in der Automatisierungstechnik
Authors: Mersch Henning
Published: December 2020

Für die Weiterentwicklung der Automatisierungstechnik ist die erweiterte Zusammenarbeit der ­automatisierungstechnischen Geräte wichtig. Viele aktuelle Themen, wie „Industrie 4.0“ oder „Cyber Physical Systems“ gehen davon aus, dass Informationen aus dem Engineering zur Produktionszeit bereit stehen. In der Automatisierungstechnik wird dafür immer mehr angestrebt, Modelle zur Beschreibung der unterschiedlichsten Sachverhalte zu nutzen. Dabei werden Themen-spezifische Modelle entwickelt, die unabhängig voneinander eigene Blickwinkel der Automatisierungstechnik auf eine Anlage beschreiben. Die vorliegende Arbeit beschreibt Mittel, um diese Modelle zur Anwendung zu bringen, verzichtet dabei aber auf ein zentralistisches Modell: Existierende, heterogene Modelle werden durch eine verteilte, dynamische Ausführungs­umgebung für Modelle und Dienste in der Automatisierungstechnik nutzbar gemacht, welche kollaborative Ansätze zur gemeinsamen Datenhaltung auf unterschiedlichen Ger...

Zur Instationären Unwuchtidentifikation Modellgestütztes Auswuchten von Rotoren mit drehzahlveränderlichen Parametern
Authors: Siegl Benjamin
Published: December 2020

Die vorliegende Arbeit wendet sich an Ingenieure und Wissenschaftler im Bereich der Auswuchttechnik und Rotordynamik. In ihr wird ein Unwuchtidentifikationsverfahren im Zeitbereich entwickelt, das mit nur einem schnellen Hoch- oder Auslauf ohne Testunwuchtsatz auskommt. Dadurch wird die Meßprozedur im Vergleich zu klassischen Verfahren verkürzt. Außerdem sind die während des Durchlaufs von Resonanzen auftretenden Schwingungsamplituden gegenüber quasi-stationären Meßläufen deutlich verringert. Die Besonderheit bei dem in dieser Arbeit entwickelten Verfahren ist, daß sich die Systemmatrizen der Bewegungsgleichungen mit der Drehzahl ändern dürfen. Somit können Systemänderungen während des instationären Meßlaufs berücksichtigt werden, beispielsweise durch Kreiselwirkung oder Gleitlagerung. Das vorgestellte Auswuchtverfahren wird anschließend an einigen Rotorsystemen – darunter einem Rotor in aktiven Magnetlagern und einem in Schwimmbuchsen gelagerten Abgasturbolader –...

Erhöhung der Elektromigrationsrobustheit in der Verdrahtung digitaler Schaltungen
Authors: Bigalke Steve
Published: December 2020

Studien zur zukünftigen IC-Entwicklung sagen einvernehmlich voraus, dass die Zuverlässigkeit zukünftiger integrierter Schaltungen (ICs) stark durch das Auftreten von Elektromigration (EM) gefährdet ist. Ursache ist die anhaltende Strukturverkleinerung im IC, welche nicht nur zur Erhö- hung der EM-Gefahr, sondern auch zur gleichzeitigen Abnahme der EM-Grenzwerte führt. Digitale Schaltungen sind auch gefährdet, da sie bisher bei der EM-Berücksichtigung vernachlässigt wurden, sodass geeignete Gegenmaßnahmen fehlen. Aus diesem Grund muss ein Paradigmenwechsel im Layoutentwurf vollzogen werden, welcher das traditionell nach der Layouterstellung stattfndende Verifzieren der EM-Robustheit durch einen proaktiven EM-robusten Layoutentwurf ersetzt. Ziel dieser Arbeit ist es, die dafür notwendigen Neuentwicklungen in der Verdrahtung digitaler Schaltungen vorzustellen. Das umfasst den Aufbau eines EM-Modells,

Experimentelle und numerische Bestimmung strukturmechanischer und akustischer Eigenschaften von metallischen Hohlkugelstrukturen
Authors: Winkler Rolf
Published: December 2020

Die vorliegende Arbeit befasst sich mit der Charakterisierung mechanischer und akustischer ­Eigenschaften von metallischen Hohlkugelstrukturen. Dieser relativ junge zellulare Werkstoff ­kennzeichnet sich durch seine besondere Zellmorphologie aus. Im Gegensatz zu bisher ­bekannten Metallschäumen weist der Strukturaufbau mit Hohlkugeln geringere Abweichungen in der Zellgröße und -anordnung auf. Ausgehend von geringeren Unregelmäßigkeiten in ihrem Strukturaufbau werden die Eigenschaften der Hohlkugelstrukturen oftmals als isotrop angenommen. Die meisten bisherigen analytischen und numerischen Betrachtungen beschränkten sich auf ideale Hohlkugelanordnungen, während sich der Großteil der experimentellen Untersuchungen mit zufälligen Anordnungen beschäftigt. Aus dieser Diskrepanz heraus ergibt sich die Motivation dieser Arbeit. Der Schwerpunkt liegt in der Analyse des anisotropen mechanischen und akustischen Verhaltens unter dem Einfluss unregelmäßiger bzw. beliebiger Hohlkuge...
Bayesian Environment Representation, Prediction, and Criticality Assessment for Driver Assistance Systems
Authors: Schreiner Matthias
Published: December 2020

This work deals with the questions i) how to represent the driving environment in an environment model, ii) how to obtain such a representation, and iii) how to predict the traffic scene for critica­lity assessment. Bayesian inference provides the common framework of all designed methods. First, Parametric Free Space (PFS) maps are introduced, which compactly represent the vehicle environment in form of relevant, drivable free space while suppressing irrelevant details of ­common occupancy grids. They are obtained by a novel method for grid mapping and tracking in dynamic environments. In addition, a maneuver-based, long-term trajectory prediction and criticality assessment system is introduced together with the Time-To-Critical-Collision-Probability (TTCCP) metric for uncertain, multi-object driving situations. Finally, the Advanced Driver Assistance System (ADAS) PRORETA 3 is described, which constitutes an integrated approach to collision avoidance and vehicle automation.

Model-based and Experimental Analysis of Transient Electrodialysis Processes
Authors: Johannink Matthias
Published: December 2020

This thesis is concerned with the integration of a model-based and experimental analysis for the systematic investigation of transient electrodialysis (ED) processes. In this context a mechanistic process model for transient ED systems is developed which is based on a rigorous dynamic description of the underlying ionic transport processes. Important requirements for a systematic model development are elaborated in a systematic manner. This includes the development of a new method for the characterization of partial differential-algebraic equations and an experimental sensitivity analysis of a transient electrodialysis system. The findings can easily be generalized to related electrochemical processes such as fuel cells or batteries. By this means this work provides important results for scientist and engineers in the fields of mechanistic modeling, electromembrane processes and electrochemical systems.

Published: December 2020

Titanium dioxide (TiO2) nanoparticles are extensively manufactured due to their potential properties and applications in various fields such as biomedical, electrical and environmental. These particles are likely to reach the aquatic environment and may cause adverse effects on aquatic organisms. In this study, we investigated the effects of different concentrations (1, 50 and 100 mg L-l) of TiO2 nanorods (NRs). The enzymatic activity of glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), and lactate dehydrogenase (LDH) was measured in the liver and muscle of an Indian major carp, Cirrhinus mrigala, under short-term exposure (96 h). The synthesised particles were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy (UV-Vis) and photoluminescence (PL) techniques before conducting the toxicity assay. The GOT and GPT activities were significantly elevated in both liver and muscle of fish treated with TiO2 nanorods (except 50 mg L-l in muscle for GPT). Similarly, the activity of LDH was also found to be elevated. The findings of the present investigation suggest that TiO2:NRs might have be absorbed, circulated, accumulated in liver and muscles of C. mrigala resulting in alterations in the enzyme activities. The results revealed that TiO2 nanorods induced alterations in GOT, GPT and LDH activities of fish at tested concentrations. The alterations of these enzymatic parameters can be useful for monitoring the environmental contamination of titanium dioxide (TiO2) nanoparticles in freshwater ecosystem.
Culture‑Bound Syndromes and Cultural Concepts of Distress in Psychiatry
Authors: Teodoro Tomás , Afonso Pedro
Published: December 2020

Culture‑bound syndromes (CBS) and cultural concepts of distress include syndromes or disease manifestations whose occurrence is related to particular cultural contexts. The term CBS is controversial, because ultimately all psychiatric and medical conditions are associated with culture. They constitute different points of view on mental health based on alternative explanatory models of mental distress. These idioms of distress have experienced a growing interest in Western countries either by an increase in the number of cases or the influence that transcultural psychiatry has come to conquer. This review describes clinical, epidemiological and contextual characteristics of most commonly reported CBS and briefly discusses the relationship between culture and psychiatric disorders. Modern societies are increasingly multi‑ethnic and multicultural and thus, discussion of these concepts remains relevant, aiming to integrate CBS in current classification systems or establishing criteria that best define them as legitimate nosological entities.

The solution of social insecurity because of Economic causes is also discussed in the light of Teachings of Holy Prophet.
A legal status of paper currency in view of Muslim Scholars in the Sub-Continent
Authors: Ahmed Muhammad Mashhood , Prof. Dr. Shabib ul Hasan  , Saifee Dr. Aziz ur Rehman
Published: December 2020

This study was conducted to determine the relevant fatwas of different clerics of different school of thoughts regarding paper currency and further to discuss the pros and cons and explanations regarding it, given by Muslim scholars, in the Sub-Continent. The paper currency is a new concept whose existence and something similar to it did not exist in the era of “Quroon-e-Uoola” (قرونِ اولی) i.e. early days of Islam. Therefore its status is neither mentioned in Quraan nor in Sunna nor discussed in the lives of “Aaima-e-Mujtah-e-deen” implying four ‘fiqhi’ Imam i.e. Imam Abu Hanifa, Imam Shafai, Imam Malik and Imam Hanbal (R.A). Islam is the most comprehensive religion owing to its inclusive teachings that has the capacity and depth to be a shining light for human being in every areas of life through its guidance. The Imams meanwhile have prescribed such principles and rules in accordance with the teaching of Quraan and Sunnah which provides us with resolution of our problems and disputes for good. Therefore, the same guidance (Quran, Sunna and fiqhi rulings) aids us in shedding light on the issue of paper currency after undertaking an analysis at length. The results would be different since different people have different opinions, causing a debate among various scholars, while making it debatable. Our scholars just as well have different point of views about the status of paper currency in light of Islamic jurisprudence since each of them has developed their opinions according to their research carried out by them respectively.

Introduction: Lithium disilicate-based ceramics are extensively used in restorative dentistry, considering these materials combines adequate mechanical and optical properties, which, associated with dentin bonding by resin luting cement, makes them suitable for load-bearing posterior regions. This case report aims to describe the clinical and laboratory steps of a ceramic crown restoration.

Case Report: A 30-year-old female patient had the second right maxillary premolar restored with lithium disilicate. The tooth was conditioned with phosphoric acid 37, followed by washing with water and drying with air jet. After this stage, the adhesive was applied to the surface and blasted with air. The prosthetic part was prepared with 10% hydrofluoric acid on the internal surface, washed with water, application of silane and adhesive. For definitive cementation, resinous cementing agent was used on the internal surface, the excess was removed and photopolymerization was performed.

Conclusion: This case report represents a successful esthetic treatment and shows resistant ceramic restorations that can be placed over minimally invasive tooth preparations.
O Processo de Individuação Psicanalítico como Modo de Subjetivação em Contextos Neoliberais
Authors: Antonio Maria Carolina Araujo
Published: December 2020

Este artigo busca entender o processo de construção de um modo subjetivação implícito na concepção de sujeito desejante produzida pela teoria psicanalítica lacaniana e operacionalizada pelos psicanalistas no processo terapêutico. Por meio da análise dos dados recolhidos em etnografia realizada em instituições lacanianas de formação de psicanalistas, o objetivo aqui é apreender como estes psicanalistas concebem a articulação entre teoria e clínica psicanalítica, como tal articulação resulta em uma concepção específica de pessoa que orienta a produção de realidades psicológicas. A terapêutica direciona o gerenciamento da vida/saúde a partir de conceitos como falta estrutural, singularidade e responsabilização, que são mobilizados pelos psicanalistas e incorporados pelos analisantes no modo de compreensão de si. Argumenta-se a relação da psicanálise com o sistema de pensamento neoliberal, uma vez que mobiliza certa noção de pessoa presente nas sociedades ocidentais, a saber, o indivíduo autônomo, livre, porém em incessante busca por satisfação. A psicanálise se mostra não só como reflexo do contexto social no qual se insere, como espaço de elaboração de seus mecanismos de agenciamentos. Com isso, se evidencia, através da etnografia, os processos de individuação presentes no modo de subjetivação inerente aos contextos neoliberais.
