The human hippocampus and its significance in neuropsychology and disease

This article discusses the structure, anatomical connections, and functions of the hippocampus (HC) of the human brain and its significance in neuropsychology and disease. The HC is concerned with the analysis of highly abstract data derived from all sensory systems but its specific role remains controversial. Hence, there have been three major theories concerning its function, viz., the memory theory, the spatial theory, and the behavioral inhibition system (BIS) theory. The memory theory has its origin in the surgical destruction of the HC, which results in severe anterograde and partial retrograde amnesia. The spatial theory has its origin in the observation that neurons in the HC of animals show activity related to their location within the environment. By contrast, the behavioral inhibition theory suggests that the HC acts as a ‘comparator’, i.e., it compares current sensory events with expected or predicted events. If a set of expectations continues to be verified then no alteration of behavior occurs. If, however, a ‘mismatch’ is detected then the HC intervenes by initiating appropriate action by active inhibition of current motor programs and initiation of new data gathering. Understanding the anatomical connections of the hippocampus may lead to a greater understanding of memory, spatial orientation, and states of anxiety in humans. In addition, HC damage is a feature of neurodegenerative diseases such as Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), Pick’s disease (PiD), and Creutzfeldt-Jakob disease (CJD) and understanding HC function may help to explain the development of clinical dementia in these disorders.

Double or quits: should money found be risked?

This article examines social attitudes towards risk-preference and risk-aversion. First, we briefly discuss the theoretical approach to the analysis of risk-preference and risk-aversion that was developed within rational choice theory. Next, we present an approach to operationalise risk-preference using survey data. Our measurement of attitudes towards risk follows the usual strategy: respondents are asked to choose between a small amount of money they get for sure, and a large but risky amount. Drawing on the theoretical models and earlier empirical research, we formulate hypotheses about the social factors that have an impact on actual decision making in the situations under study. The hypotheses are tested using survey data. The article ends with a brief discussion. The novelty of our paper is that – to the best of our knowledge – neither previous Hungarian nor international research has attempted to examine attitudes towards risk using data from large-scale surveys.

Fogalmak, módszerek. Páros összehasonlításokon alapuló rangsorolási módszerek (Ranking methods based on paired comparisons)

A páronként összehasonlított alternatívák rangsorolásának problémája egyaránt felmerül a szavazáselmélet, a statisztika, a tudománymetria, a pszichológia és a sport területén. A nemzetközi szakirodalom alapján részletesen áttekintjük a megoldási lehetőségeket, bemutatjuk a gyakorlati alkalmazások során fellépő kérdések kezelésének, a valós adatoknak megfelelő matematikai környezet felépítésének módjait. Kiemelten tárgyaljuk a páros összehasonlítási mátrix megadását, az egyes pontozási eljárásokat és azok kapcsolatát. A tanulmány elméleti szempontból vizsgálja a Perron-Frobenius tételen alapuló invariáns, fair bets, PageRank, valamint az irányított gráfok csúcsainak rangsorolásra javasolt internal slackening és pozíciós erő módszereket. A közülük történő választáshoz az axiomatikus megközelítést ajánljuk, ennek keretében bemutatjuk az invariáns és a fair bets eljárások karakterizációját, és kitérünk a módszerek vitatható tulajdonságaira. _____ The ranking of the alternatives or selecting the best one are fundamental issues of social choice theory, statistics, psychology and sport. Different solution concepts, and various mathematical models of applications are reviewed based on the international literature. We are focusing on the de¯nition of paired comparison matrix, on main scoring procedures and their relation. The paper gives a theoretical analysis of the invariant, fair bets and PageRank methods, which are founded on Perron-Frobenius theorem, as well as the internal slackening and positional power procedures used for ranking the nodes of a directed graph. An axiomatic approach is proposed for the choice of an appropriate method. Besides some known characterizations for the invariant and fair bets methods, we also discuss the violation of some properties, meaning their main weakness.

New Public Management Reforms: Institutions matter!

New Public Management (NPM) has played a decisive role and has had a radical effect on the productivity and efficiency of the public sector in the Anglo-Saxon countries. However, the effective introduction of the NPM reforms is not an easy task. The scientific community is zealously analyzing the experiences of the developing countries. The stories, they tell, are full of failures, and ineffective reforms. The goal of the current study is to uncover the factors that might influence the successful implementation of the NPM reforms. In our analysis, by relying on the theories of new institutional economics, we developed a model with which we wish to prove that in regards to the success of the reforms the informal and the formal institutions characteristic of the given country are the decisively determining factors. When answering the question, we introduced a new indicator based on public choice theory – the politicians’ interest index – by which we could measure the success of the NPM. We tested our hypothesis by a comparative statistical analysis using the data from 31 countries. Based on our results, we find that informal institutions, the culture shared by the members of society, fundamentally determine the probability of the successful implementation of the NPM reforms, these results having a significant practical relevance.

Participative Budgeting and Participant Motivation: A Review of the Literature

In their discussion - Participative Budgeting and Participant Motivation: A Review of the Literature - by Frederick J. Demicco, Assistant Professor, School of Hotel, Restaurant and Institutional Management, The Pennsylvania State University and Steven J. Dempsey, Fulton F. Galer, Martin Baker, Graduate Assistants, College of Business at Virginia Polytechnic Institute and State University, the authors initially observe: “In recent years behavioral literature has stressed the importance of participation In goal-setting by those most directly affected by those goals. The common postulate is that greater participation by employees in the various management functions, especially the planning function, will lead to improved motivation, performance, coordination, and functional behavior. The authors analyze this postulate as it relates to the budgeting process and discuss whether or not participative budgeting has a significant positive impact on the motivations of budget participants.” In defining the concept of budgeting, the authors offer: “Budgeting is usually viewed as encompassing the preparation and adoption of a detailed financial operating plan…” In furthering that statement they also furnish that budgeting’s focus is to influence, in a positive way, how managers plan and coordinate the activities of a property in a way that will enhance their own performance. In essence, framing an organization within its described boundaries, and realizing its established goals. The authors will have you know, to control budget is to control operations. What kind of parallels can be drawn between the technical methods and procedures of budgeting, and managerial behavior? “In an effort to answer this question, Ronen and Livingstone have suggested that a fourth objective of budgeting exists, that of motivation,” say the authors with attribution. “The managerial function of motivation is manipulative in nature.” Demicco, Dempsey, Galer, and Baker attempt to quantify motivation as a psychological premise using the expectancy theory, which encompasses empirical support, intuitive appeal, and ease of application to the budgetary process. They also present you with House's Path-Goal model; essentially a mathematics type formula designed to gauge motivation. You really need to see this. The views of Argyris are also explored in particular detail. Although, the Argyris study was primarily aimed at manufacturing firms, and the effects on line-supervisors of the manufacturing budgets which were used to control and evaluate their performance, its application is relevant to the hospitality industry. As the title suggests, other notables in the field of behavioral motivation theory, and participation are also referenced. “Behavioral theory has been moving away from models of purported general applicability toward contingency models that are suited for particular situations,” say the authors in closing. “It is conceivable that some time in the future, contingency models will make possible the tailoring of budget strategies to individual budget holder personalities.”

Yrkesverksamma högstadielärares syn på det fria skolvalet utifrån ett segregations- och mångfaldsperspektiv

Den här uppsatsen behandlar det fria skolvalet ur ett mångfalds- och segregationsperspektiv där yrkesverksamma högstadielärare har intervjuats angående hur de upplever att det fria skolvalet påverkar den svenska skolan ur ett segregations- och mångfaldsperspektiv. Studien har varit kvalitativ och har använt sig av intervjuer som empirisk insamlingsmetod. Empirin har presenterats för att sedan analyseras med hjälp av två analysverktyg: Rational Choice Theory och Strukturalism. Lärarna upplevde det fria skolvalet som en påverkansfaktor utifrån både ett segregations- och mångfaldsperspektiv, där det fria skolvalet inte enbart har varit negativt.

O processo de criação do programa Universidade para Todos - PROUNI

From the end of the 80s, the Brazilian higher education experience strong growth, coming from the private sector, which would intensify further in the late 90th Higher education has become a lucrative business. With a drop in the number of students entering and strong competition, the number of idle places in private institutions of higher education reached 49.5% in 2004. That same year, by Measure, was the University for All Program (PROUNI) program, to include high school students from public higher education, offering scholarships to those students in private HEIs. In exchange, the IES gain tax exemption. The objective of this research is to investigate the game of interest occurred in the formulation of this program and identify the model and the political game and has led to the creation of PROUNI, analyzing the process occurred since the wording of a bill, the issue of Measure Law and that the legitimacy PROUNI, with the most important changes made initial model. Since the first draft of the Law to the final Act, the PROUNI was disfigured in its main points, as the percentage of stock for paying students, the process of selection of stock and bond of the IES program. Throughout the process of creating the program, it is quite clear the performance of the institutions representing the private higher education. As reference for the analysis was based on Rational Choice Theory of Political Science. The basic argument of the methods based on rational choice is the maximization of the benefit will be the main motivation of individuals, but they can give that your goals can be achieved more effectively through institutional action and thereby discover that their conduct is shaped by institutions. Thus, individuals rationally choose to get to a certain extent constrained to join in certain institutions, whether voluntarily or not. The PROUNI was submitted by government and public policy covered by the mystical aura of the discourse of social justice and economic development, as in higher education includes a stratum of people who would not have access to the university, due to restrictions in the supply network public higher education. However, the greatest benefit from the program are the private HEIs, which through a difficult time in a scenario marked by high competition and idleness of nearly half of the vacancies offered. The PROUNI became a program that prioritizes access and not the residence of the student to higher education. More serious than a supporting program for students Fellows is a program supporting the institutions of private education

Tackling trafficking in human beings in a security integrated Europe: addressing the challenges using trafficking schematics

This paper aims to conceptualise trafficking in human beings (THB) as an organised crime by drawing on the rational choice theory. Utilising crime scripting principles, it proposes trafficking schematics to capture and visualise THB in its entirety. Stemming from its transnational nature and varying conceptualisations, combatting THB faces challenges, such as the lack of harmonisation of policy instruments and differing stakeholder agendas. To mitigate these challenges, this paper proposes trafficking schematics. Their core lies in the modelling of THB constituent elements, including stages and their sequence, key actors and relationships, and financial modus operandi. Trafficking schematics may therefore contribute to addressing THB in a holistic, dynamic and integrated way, by enriching stakeholders’ understanding of the phenomenon and facilitating collaboration to address it. The paper contributes to theory and practice by drawing up a model of the procedural, human, logistical and environmental elements of THB that may be viewed as an instrument of public value creation.

Second choices in a visual span of apprehension task

Four Ss were run in a visual span of apprehension experiment to determine whether second choices made following incorrect first responses are at the chance level, as implied by various high threshold models proposed for this situation. The relationships between response biases on first and second choices, and between first choice biases on trials with two or three possible responses, were also examined in terms of Luce's (1959) choice theory. The results were: (a) second choice performance in this task appears to be determined by response bias alone, i.e., second choices were at the chance level; (b)first and second choice response biases were not related according to Luce's choice axiom; and (c) the choice axiom predicted with reasonable accuracy the relationships between first choice response biases corresponding to trials with different numbers of possible response alternatives. © 1967 Psychonomic Society, Inc.

La institucionalización de la lucha contra el terrorismo transnacional a través del derecho internacional

Hasta hace casi una década, la guerra contra el terrorismo fue una lucha solitaria de los Estados. Actualmente y debido a las implicaciones globales de este fenómeno, las acciones contra este flagelo han adquirido connotación internacional. Gran parte de los países miembros de las Naciones Unidas han acogido esta guerra –contra un enemigo común, pero indefinido- como un compromiso político en favor de la paz y seguridad internacional. La producción constante de instrumentos internacionales que condenan el terrorismo y que exigen tomar medidas para combatirlo, demuestran que esa intención política originaria se ha decantado en el ordenamiento internacional como una obligación autónoma, de carácter consuetudinario; que hace que actualmente no haya país en el mundo que pueda excusarse de combatir al terrorismo (interno o transnacional) independientemente de las justificaciones que se puedan aludir para el no cumplimiento.

Argumentación, decisión y justificación: retratos de conversos al Islam en Bogotá

Los estudios de las prácticas sociales se han abordado desde diversas perspectivas. Algunas se enfocan principalmente en el rol de las instituciones, estructuras o de las ideologías para la comprensión de las prácticas sociales; mientras que otras, de manera opuesta, se han enfocado en el estudio de las acciones de los individuos. La presente investigación se afilia a esta segunda perspectiva del estudio social y a partir de la misma estudia un fenómeno social particular, el cual es, el fenómeno de la conversión religiosa. A partir del estudio de las acciones de los individuos y, principalmente, de las argumentaciones y justificaciones que dan de la misma, el presente documento busca dar cuenta de los motivos que fundamentan e impulsan la conversión y el cambio radical dentro del sistema de creencias del Individuo.

The Allocation of Asylum Responsibilities in the EU: a Law & Economics Analysis

This dissertation focuses on how the design of the EU asylum allocation system, the system that allocates the EU’s asylum duties to its member states, relates to the development of asylum crises. The current EU asylum allocation system, the Dublin system, has in the literature frequently been blamed as an important factor that contributed to the events that occurred during the 2015/2016 EU Asylum Crisis. In the first part of this dissertation, I use a Law & Economics methodology based on rational choice theory to study how the Dublin system creates behavioural incentives for both asylum seekers and member states and how this relates to the events during the 2015/2016 EU Asylum Crisis. In the second part, I analyse how behavioural incentives for asylum seekers and member states would change if the EU would replace the Dublin system with a so-called (tradable) quota system. By comparing the outcomes of the first and the second part of the dissertation I make some normative recommendations on desirable features for an EU asylum allocation system that provides better incentives for asylum seekers and member states.
