Discrimination of multidimensional geometrical figures by chickens: categorization and pattern-learning

Japanese bantam hens were trained to discriminate between geometrical figures varying along four integral dimensions. Only one dimension predicted food: selections of sharp-cornered figures were reinforced, while selections of rounded figures were not. In experiment 1, hens were subsequently trained to discriminate between nine figure pairs in a simultaneous discrimination task. Because single pairs contained multiple redundant cues, whereas the relevant dimension was obvious only across stimulus pairs, the results revealed effects of both generalization and reversal learning. Accordingly, learning speed was enhanced for later discriminations. Experiment 2 tested the hens’ transfer performance to unknown pairs, following experience of 9 or 18 figure pairs. Four of seven hens showed reliable transfer after experience with 9 figures, but only three showed transfer after experience with 18 figures, indicating lower transfer with higher number of stimulus pairs learned. In experiment 3, hens were trained to discriminate 27 figure pairs. Discrimination ratios further decreased and the groups of pairs differed significantly in their ratios of discrimination. Individual hens’ pecking behaviour was analysed in relation to each dimension of single figures and in relation to relative differences in the levels of dimensions between paired figures. Hens were shown to be oriented towards irrelevant information and more towards relational and configurational than elemental and dimensional aspects. The results are discussed in the biological context of individual recognition in chickens’ dominance hierarchies, in which we suppose that chickens identify individual flock mates by representation of their visual pattern rather than by single characteristics.

关于城市伦理的几个问题

城市伦理研究城市社会的道德问题。城市伦理研究所运用的是结构—功能分析、城市和乡村社会结构的比较、辩证唯物主义和历史唯物主义等方法。环境的高度人工化、社会交往和联系的普遍性、职业分工的扩张趋势、价值主体的多元化构成了城市社会的道德机制。由此形成了城市道德的基本特征 :道德形成的共识性、价值的终极指向性、职业道德的社会化、功能上的整合性、适用的普世性、内容上的开放性。传统道德对当代城市道德既有消极阻碍的作用又有积极的构成作用。

Religious Organizations and Government: An Ecclesial Lutheran “Take”

Sharp debates exist today about the appropriate relationship between religious organizations and government, with views ranging from Christian nationalism to strict secularists. This essay explores a mediating position expressed in the conceptual phrase that religious bodies should “work with civil authorities in areas of mutual endeavor, maintaining institutional separation and functional interaction.” The essay uses historical and ecclesial sources to describe the struggles and underpinnings that lead to this position and then unpacks its meaning and import. While originating from within the conceptual and ecclesial American Lutheran tradition, the essay points to this approach as a public proposal for sound relationship between religious communities and political authority in the United States.     

The meaning of masculinity for educated young Bedouins

Israel's Bedouin population—an Indigenous, traditional, collective, patriarchal society—is at the height of social change, introducing modernization, religion and altered gender relations. Young Bedouin men are experiencing the ramifications of their masculine identity. As in other collective societies that emphasize mutual dependence and cooperation, honour has great meaning and unlike individualistic societies, maintaining masculine and family honour is important in the construction of masculinity. These cultural differences may influence young men's views of honour, particularly family honour, which is a key principle in collective cultures. An exploratory qualitative study used semi-structured interviews of 20 educated Bedouin young men and grounded theory to investigate what masculinity means for them. They defined masculinity by comparing theirs to that of the ‘other’. They also described the crucial evaluators of masculinity: the family's older men. Protection and close supervision of women were found to be key factors in the assessment of masculinity. Also evident was the influence of the men's education on their gendered perceptions and their use of Western-oriented language regarding egalitarianism and women's rights. The findings may contribute to social work practice, especially in patriarchal societies, and may help in understanding how men may use their patriarchal power to generate change.

The deliberate university: Remarks on the ‘Idea of the University’ from a perspective of knowledge

The current discussion on the role of the (European) universities often starts off with a perspective on the university as a scientific and/or pedagogical institution and consequently runs into a conflict between both logics in which each element is somehow devalued from the other perspective. Therefore, it may be productive to analyse the university from a standpoint in between, a perspective of knowledge as such. In order to conceptualise such a third perspective of knowledge, the history of the European university is reconstructed and interpreted as a process of reflection on the ‘spiral of knowledge’. Before this background the idea of the university is renewed in terms of knowledge and summarised in the idea of a ‘deliberate university’.

Using Social Representations Theory to Examine Lay Explanation of Contemporary Social Crises: The Case of Ireland's Recession

Social actors operate under a basic imperative to construct explanations for the events that surround them. Many issues that dominate the societal agenda today are not available to direct perception, derive from traditionally expert domains and are relatively remote from immediate local experience. This presents a challenge for lay explanation of these issues. Social representations theory offers a useful framework through which the construction of lay explanation for such issues can be examined. The current study recruited this theoretical framework to investigate lay explanations of the recent economic recession in Ireland. Data consisted of semi‐structured interviews with 14 members of the public and a web‐based survey (N = 138). The data suggested that explanations for the recession could be organised into three major themes: Power, Ordinary People and Fatalism. Strictly economic explanations were eschewed; instead, people drew upon a wide range of ideas about society, politics, morality, public spheres and personhood. The implications of these findings for understanding lay explanation of contemporary social crises are discussed. Copyright © 2011 John Wiley & Sons, Ltd.     

Open society fosters satisfaction: explanation to why individualism associates with country level measures of satisfaction

ABSTRACT

Although the association between individualism and satisfaction in societies is well documented, the precise mechanism linking these two remained understudied so far. Here we coin and describe the specific facet of individualism responsible for the above association–the ‘open society’. Open societies foster four others-benefitting attitudes: tolerance, trust, civic engagement, and minimization of materialistic pressure. In the others-benefitting qualities of these four attitudes, this paper finds the mechanism promoting life satisfaction of societies. Further, when open society attitudes are controlled for, the most common facet of individualism (quantified by Hofstede) turns out to be a negative predictor of satisfaction in societies. At the individual level of analysis, the relation of endorsement of four open society attitudes with individual life satisfaction is almost absent. Thus, open society promotes the satisfaction of communities in a eusocial way only.     

Normative systems theory for sustaining democracy

Democracy is the most widely admired type of political system but also perhaps the most difficult to maintain. If democracy does not operate by the principles of justice, the people may prefer to be governed through their own consent. Legitimacy requires effective performance. But effectiveness may be sacrificed to consent. Democracy is sustainable when its institutional framework promotes normatively desirable and politically desired objectives. It can be said that the viability of a democratic system depends on the principle of justice, which leads to the functioning of autopoietic system in the complex environment of civil society.
