“…we have to take into account the fact that museology and museums are two completely different things.” Martin R. Shärer[1] In the 20th century, growing populations produced a growing body of heritage. The transmission of this heritage to succeeding generations coalesced into three major modern institutions: universities, library/archives and museums. Traditional systems of social and cultural memory had become overloaded and therefore evolved conceptually. This evolution took place within the primary context of a naturally occurring museology through the process I call museogenesis. The term museogenesis refers to the origin and development of museological thought in a specific cultural context. By museological thought, I refer to ideas and theories surrounding the parameters of “the natural and cultural heritage, the activities concerned with the preservation and communication of this heritage, the institutional frame-work, and society as a whole” (Mensch 1992). This broadly inclusive definition relates museology to another broadly defined concept: cultural context. By cultural context, I refer to the “webs of significance and systems of meaning which is the collective property of a group” (Geertz 1973). [1] ICOFOM Study Series – ISS 34, 2003, ISS 34_03.pdf, p.7

Durante la turbulenta década de 1930, los intelectuales de Ecuador encontraron en la Guerra Civil española un conflicto que se presentaba como un espejo para las inquietudes y las esperanzas de su propio país. Este artículo esboza una breve contextualización de la situación política bajo los gobiernos de Federico Páez y Alberto Enríquez Gallo y señala las diferentes actitudes de los dos presidentes ante la guerra española. Estudia el impacto que tuvo la guerra en intelectuales de izquierda y derecha. También examina la manera en que poetas, narradores, ensayistas y periodistas emprendieron un activismo apasionado a favor de los dos bandos (la España “leal” y la España “nacionalista”), en poemas y artículos notables por su emoción y su maniqueísmo y en la organización colectiva de manifestaciones, asambleas, revistas, manifiestos y colectas.

En este artículo se analiza la evolución histórica de los flujos migratorios entre Ecuador y Europa. Se observa una nueva migración europea hacia Ecuador y otros países suramericanos, pese a lo cual la Unión Europea no ha adaptado su política migratoria a esta nueva realidad. Por tanto, se plantea la necesidad de que la UE elimine el requisito de visado a los ciudadanos ecuatorianos. Se presentan escenarios así como estrategias para lograr ese objetivo, incluida una propuesta de solidaridad y acción colectiva de UNASUR en materia de visados.

This paper aims to analyze the decision issued by the Constitutional Court for Transition within the unconstitutionality presented against the Mining Act. Proponents, in the main, formal allege unconstitutional by the Mining Law have been issued by the Committee on Legislation and Oversight (National Assembly during the Transitional Period after the adoption of the 2008 Constitution) without the prior execution of a legislative pre query, this query being a collective right of national, indigenous peoples and communities recognized in Article 57 paragraph 17 of the Constitution of the Republic. The Constitutional Court ruled Transition to reject the unconstitutionality confirming the constitutionality of the regulatory body and the substantial and non-formal pre-legislative consultation.

For many networks in nature, science and technology, it is possible to order the nodes so that most links are short-range, connecting near-neighbours, and relatively few long-range links, or shortcuts, are present. Given a network as a set of observed links (interactions), the task of finding an ordering of the nodes that reveals such a range-dependent structure is closely related to some sparse matrix reordering problems arising in scientific computation. The spectral, or Fiedler vector, approach for sparse matrix reordering has successfully been applied to biological data sets, revealing useful structures and subpatterns. In this work we argue that a periodic analogue of the standard reordering task is also highly relevant. Here, rather than encouraging nonzeros only to lie close to the diagonal of a suitably ordered adjacency matrix, we also allow them to inhabit the off-diagonal corners. Indeed, for the classic small-world model of Watts & Strogatz (1998, Collective dynamics of ‘small-world’ networks. Nature, 393, 440–442) this type of periodic structure is inherent. We therefore devise and test a new spectral algorithm for periodic reordering. By generalizing the range-dependent random graph class of Grindrod (2002, Range-dependent random graphs and their application to modeling large small-world proteome datasets. Phys. Rev. E, 66, 066702-1–066702-7) to the periodic case, we can also construct a computable likelihood ratio that suggests whether a given network is inherently linear or periodic. Tests on synthetic data show that the new algorithm can detect periodic structure, even in the presence of noise. Further experiments on real biological data sets then show that some networks are better regarded as periodic than linear. Hence, we find both qualitative (reordered networks plots) and quantitative (likelihood ratios) evidence of periodicity in biological networks.

This article investigates the ideology of Al-Qaeda as perceived from within the network. Particular attention is paid to the ideological background of Al-Qaeda's intellectual leadership, its sociopolitical context and the nature of its recruits. The inner logic of the Al-Qaeda organisation advances an intellectual concept that is not based on the main schools of Islamic theology, but on a new ideological starting point that results from the application of Islamic principles to sociopolitical change. With its political goals reinforced by the teachings of the Quran, exemplified by the content and rhetoric of a recently discovered training manual, the organisation creates powerful imagery embedded in the collective consciousness of the Muslim community. Thus, the message provided by Al-Qaeda inspires its followers to commit violent acts of destruction while being fully convinced that they are fulfilling the ordained will of Allah.

Cooperative housing is a long-established form of housing tenure found in many countries. This article will examine the different definitions and forms of cooperative housing and the different roles it has donned in a number of countries, including the United Kingdom and Sweden. The philosophy behind this form of housing will be described. The pragmatic reasons for its existence, such as the need for a collective form of tenure to deal with common repair problems, will also be discussed. The main areas of research on housing cooperatives will be described: (i) their efficiencies being compared with those of other tenure forms and (ii) identifying the factors that influence resident involvement.

The term neural population models (NPMs) is used here as catchall for a wide range of approaches that have been variously called neural mass models, mean field models, neural field models, bulk models, and so forth. All NPMs attempt to describe the collective action of neural assemblies directly. Some NPMs treat the densely populated tissue of cortex as an excitable medium, leading to spatially continuous cortical field theories (CFTs). An indirect approach would start by modelling individual cells and then would explain the collective action of a group of cells by coupling many individual models together. In contrast, NPMs employ collective state variables, typically defined as averages over the group of cells, in order to describe the population activity directly in a single model. The strength and the weakness of his approach are hence one and the same: simplification by bulk. Is this justified and indeed useful, or does it lead to oversimplification which fails to capture the pheno ...

This book follows a revolutionary trend popular among young activists and would-be radicals after 1917, the formation of collective units of cohabitation and association known as 'urban communes'. In these spaces, activists tried to live what they understood as the 'socialist lifestyle', self-consciously putting Marxist and Bolshevik theories into practice. By telling the story of the urban communes, this book reveals how grand revolutionary ideals, such as collectivism, equality, proletarian ethics, and modern practice, were experienced, understood, and appropriated on a human level. This enables us to better understand the messy realities of the early Soviet state, showing how ideological beliefs and revolutionary contingencies actually came into being during this time.

We consider the time evolution of an exactly solvable cellular automaton with random initial conditions both in the large-scale hydrodynamic limit and on the microscopic level. This model is a version of the totally asymmetric simple exclusion process with sublattice parallel update and thus may serve as a model for studying traffic jams in systems of self-driven particles. We study the emergence of shocks from the microscopic dynamics of the model. In particular, we introduce shock measures whose time evolution we can compute explicitly, both in the thermodynamic limit and for open boundaries where a boundary-induced phase transition driven by the motion of a shock occurs. The motion of the shock, which results from the collective dynamics of the exclusion particles, is a random walk with an internal degree of freedom that determines the jump direction. This type of hopping dynamics is reminiscent of some transport phenomena in biological systems.

”I believe in something”: Constructions of Beliefs in Sweden Research results are dependent on how social phenomena are conceptualized. In the present article, consequences are discussed of the standardized conceptualization of religiosity as ”church-oriented”. In its place, a multifaceted approach to the phenomenon of religious belief is suggested. This approach was used for an analysis on how eleven Swedish women and men with different religious and spiritual as well as non-religious and atheist affiliation talk about beliefs. The results suggest that beliefs were meaningful because they related to specific perceptions of a Zeitgeist. It was hereafter underlined that belief in ”something” or other brief descriptions of the sacred placed the sacred outside of the individual. Finally, while subjective authority is valued for choosing to believe, this subjectivity seems in part to be dependent on collective dimensions of recognition. The value of choosing beliefs can be conceptualized as a meaningful yet analytically distinct aspect of belief co-existing with descriptions of the sacred. Thus, it is concluded that a multifaceted approach to religious belief may develop our understanding of religion and religiosity in contemporary society

The power of homosociality: how young men “do” masculinity in groups and individually Using young men’s narratives, about other men, friends, dates and girlfriends, this article discusses the following questions: Can the interpretation – the understanding of young men’s collective presentations of masculinity as a surface that hides a more complex masculinity – undermine how we interpret young men’s talk about and interaction with other men, as well as with women? Can this disassembling understanding have an impact on how young men interpret and relive the interactions with other men, as well as with women? Can this disassembling of the homosocially created masculinity from the more individually created masculinity shape secondary gains for the young men, such as e.g. a more flexible and stretchable arena of responsibility, as well as more flexible space of acting? Thomas Johansson, Professor of Social Work social work, states that if we only focus the homosocially created masculinity, this will reshape a less nuanced picture of young men’s way of doing masculinity (Johansson 2005). Thus, young men’s vulnerability and difficulties remain hidden. However, this disassembling of the homosocially created masculinity from the more individually based doings of masculinity could possibly also give secondary gains, such as e.g. a more flexible and stretchable field of responsibility, as well as more flexible space of acting. This article shows that using a fragmentised and situated masculinity, as a way of understanding the complexity and the ambivalence in young men’s project of doing masculinity, makes evident – on the one hand – the vulnerability in young men’s process of doing masculinity. On the other hand, however, this view also makes it possible for young men to avoid responsibility for their actions. Instead the situated context – e.g. if in a peer group or alone, and what kind of relations the young man has – will be significant for how the act will be interpreted. The empirical material consists of six individual interviews and one group interview with four men. The age span of the participants is 16 to 24 years old. The overall theme for the discussions is heterosexual practice and relations.

This paper investigates the income inequality generated by a jobsearch process when di§erent cohorts of homogeneous workers are allowed to have di§erent degrees of impatience. Using the fact the average wage under the invariant Markovian distribution is a decreasing function of the discount factor (Cysne (2004, 2006)), I show that the Lorenz curve and the between-cohort Gini coe¢ cient of income inequality can be easily derived in this case. An example with arbitrary measures regarding the wage o§ers and the distribution of time preferences among cohorts provides some insights into how much income inequality can be generated, and into how it varies as a function of the probability of unemployment and of the probability that the worker does not Önd a job o§er each period.

Sabatini (2002) and Roberts and Wibbles (1999) Pointed Out That Voters in Latin American Countries are no Longer Choosing According to Their Ideological Preferences. Ashworth and Heyndels (2002) Showed That the Tax Choice In Oecd Countries Does not Follow the Ideological Pattern of Party Preferences. the Most Robust Result of This Work Shows That the Tax Choice in Latin American Countries Still Depends on This Ideological Preference. We Also Verified That Changes in the Tax Structure Depend on Changes Both in the Tax Burden and the Openness of the Economy
