A Multi-Agent Architecture for An Intelligent Web-Based Educational System
An intelligent educational system must constitute an adaptive system built on multi-agent system architecture. The multi-agent architecture component provides self-organization, self-direction, and other control functionalities that are crucially important for an educational system. On the other hand, the adaptiveness of the system is necessary to provide customization, diversification, and interactional functionalities. Therefore, an educational system architecture that integrates multi-agent functionality [50] with adaptiveness can offer the learner the required independent learning experience. An educational system architecture is a complex structure with an intricate hierarchal organization where the functional components of the system undergo sophisticated and unpredictable internal interactions to perform its function. Hence, the system architecture must constitute adaptive and autonomous agents differentiated according to their functions, called multi-agent systems (MASs). The research paper proposes an adaptive hierarchal multi-agent educational system (AHMAES) [51] as an alternative to the traditional education delivery method. The document explains the various architectural characteristics of an adaptive multi-agent educational system and critically analyzes the system’s factors for software quality attributes

EU-Turkey Relations
This open access book explores the new complexities and ambiguities that epitomize EU-Turkey relations. With a strong focus on the developments in the last decade, the book provides full access to a comprehensive understanding of the multifaceted relationship through three entry points: (1) Theories and Concepts, (2) Institutions, and (3) Policies. Part I brings together complementary and competing analytical approaches to study the evolution of EU-Turkey relations, ranging from traditional integration theories to novel concepts. Part II investigates the institutional machinery of EU-Turkey relations by analyzing the roles and perspectives of the European Council, the European Commission, and the European Parliament. Part III offers analyses of the policies most relevant for the relationship: enlargement policy, trade and macroeconomic policies, foreign and security policy, migration and asylum policies, and energy policy. In Part IV, the volume closes with a systematic survey of the conditions under which cooperative trends in EU-Turkey relations could be (re)invigorated. The systematic setup and the balanced combination of distinguished experts from EU- and Turkey-based institutions make this book a fundamental reading for students, researchers, lecturers, and practitioners of EU-Turkey relations, European integration and Turkish foreign policy

Essays on bounded rationality: individual decision and strategic interaction
Economics is a social science which, therefore, focuses on people and on
the decisions they make, be it in an individual context, or in group situations.
It studies human choices, in face of needs to be fulfilled, and a limited amount
of resources to fulfill them. For a long time, there was a convergence between
the normative and positive views of human behavior, in that the ideal and
predicted decisions of agents in economic models were entangled in one single
concept. That is, it was assumed that the best that could be done in each
situation was exactly the choice that would prevail. Or, at least, that the facts
that economics needed to explain could be understood in the light of models
in which individual agents act as if they are able to make ideal decisions.
However, in the last decades, the complexity of the environment in which
economic decisions are made and the limits on the ability of agents to deal
with it have been recognized, and incorporated into models of decision making
in what came to be known as the bounded rationality paradigm. This was
triggered by the incapacity of the unboundedly rationality paradigm to explain
observed phenomena and behavior. This thesis contributes to the literature
in three different ways. Chapter 1 is a survey on bounded rationality, which gathers and organizes
the contributions to the field since Simon (1955) first recognized the necessity
to account for the limits on human rationality. The focus of the survey is
on theoretical work rather than the experimental literature which presents
evidence of actual behavior that differs from what classic rationality predicts.
The general framework is as follows. Given a set of exogenous variables, the
economic agent needs to choose an element from the choice set that is avail-
able to him, in order to optimize the expected value of an objective function
(assuming his preferences are representable by such a function). If this problem is too complex for the agent to deal with, one or more of its elements is
simplified. Each bounded rationality theory is categorized according to the
most relevant element it simplifes.
Chapter 2 proposes a novel theory of bounded rationality. Much in the
same fashion as Conlisk (1980) and Gabaix (2014), we assume that thinking
is costly in the sense that agents have to pay a cost for performing mental
operations. In our model, if they choose not to think, such cost is avoided,
but they are left with a single alternative, labeled the default choice. We exemplify the idea with a very simple model of consumer choice and identify the
concept of isofin curves, i.e., sets of default choices which generate the same
utility net of thinking cost. Then, we apply the idea to a linear symmetric
Cournot duopoly, in which the default choice can be interpreted as the most
natural quantity to be produced in the market. We find that, as the thinking
cost increases, the number of firms thinking in equilibrium decreases. More
interestingly, for intermediate levels of thinking cost, an equilibrium in which
one of the firms chooses the default quantity and the other best responds to
it exists, generating asymmetric choices in a symmetric model. Our model is
able to explain well-known regularities identified in the Cournot experimental
literature, such as the adoption of different strategies by players (Huck et al.
, 1999), the inter temporal rigidity of choices (Bosch-Dom enech & Vriend,
2003) and the dispersion of quantities in the context of di cult decision making (Bosch-Dom enech & Vriend, 2003).
Chapter 3 applies a model of bounded rationality in a game-theoretic set-
ting to the well-known turnout paradox in large elections, pivotal probabilities
vanish very quickly and no one should vote, in sharp contrast with the ob-
served high levels of turnout. Inspired by the concept of rhizomatic thinking,
introduced by Bravo-Furtado & Côrte-Real (2009a), we assume that each per-
son is self-delusional in the sense that, when making a decision, she believes
that a fraction of the people who support the same party decides alike, even
if no communication is established between them. This kind of belief simplifies the decision of the agent, as it reduces the number of players he believes
to be playing against { it is thus a bounded rationality approach. Studying
a two-party first-past-the-post election with a continuum of self-delusional
agents, we show that the turnout rate is positive in all the possible equilibria,
and that it can be as high as 100%. The game displays multiple equilibria,
at least one of which entails a victory of the bigger party. The smaller one
may also win, provided its relative size is not too small; more self-delusional
voters in the minority party decreases this threshold size. Our model is able
to explain some empirical facts, such as the possibility that a close election
leads to low turnout (Geys, 2006), a lower margin of victory when turnout is
higher (Geys, 2006) and high turnout rates favoring the minority (Bernhagen
& Marsh, 1997)
Drivers and consequences of residents' satisfaction with off-campus student housing in South-South, Nigeria
The student housing system worldwide and South-South Nigeria in particular has witnessed an unprecedented transformation, such that private off-campus student housing facilities (SHFs) are now the primary source of accommodation for students in tertiary institutions. A considerable gap exists between the supply and demand for on-campus student housing and the quest to fill this gap has stimulated the creation of a significant student housing market in the areas where these tertiary institutions are located. The prospect for economic investments in the student housing sector is high and private investors are involved in the provision and management of offcampus student housing. The main consequence of this practice in South-South, Nigeria is the delivery of low-quality buildings that are not able to meet the needs and expectations of residents. SHFs that are constructed without due regard to residents needs are characterised by dissatisfaction with attributes of housing and low investment performance. The implication is that residence users are often not satisfied with the attributes of the residential environment that are provided; thus their behaviours often impose some consequences on investors gains and objectives.Therefore, understanding the dynamics among attributes that are important to students, that give the required satisfaction, and the impact of the availability or lack-of on behaviour such as loyalty, willingness to pay for attributes and word of mouth behaviour are critical to profitability. Most often, the relationship among these attributes are treated as linear and symmetrical with the assumed implication that better attributes produce improved behaviours. However, this may not always be the case. This approach is rarely addressed and is little understood in student housing studies. Therefore, the aim of this study was to identify student housing attributes that act as drivers of resident atisfaction and the consequences/effects of these drivers on student behaviour in order to determine appropriate measures that could be used to develop, maintain and upgrade student accommodation. The methodology of the study included an extensive literature review and a field study conducted to obtain the perceptions of students in seven tertiary institutions located in South-South, Nigeria. The main task was to define attributes of student housing facilities based on the symmetric and asymmetric impact of the performance of attributes on satisfaction with residence. The Kano model and importance-performance analysis (IPA) were used to establish sets of criteria that could be used to prioritise attributes that are required in student housing for optimal investor gains. Analysis of the findings lead to the conclusions that different degrees of behaviour were associated to the perception of importance that is attached to attributes by residents and the satisfaction that is derived from the use of such attributes. The implication of the conclusions is that to meet users satisfaction needs, varied improvement strategies are required for different attributes in order to maximise the use of resources for maximum gains. The recommendations for investors in SHFs include among others to segment the SHFs market based on demographic characteristics, prioritise and provide only attributes that add-value to identified groups. Emphasis should also be placed on providing attributes that are not only satisfactory, but with capacity to improve loyalty/retention, willingness to pay and positive word of mouth behaviour. It is also recommended that the local authority should improve critical attributes that are deemed to be outside the scope of the investors
