Democratic Stability through the Concept of Reasonableness in John Rawls

The paper addresses the question of the stability of a democratic state and shows the shortcomings of the political and institutional structure for this purpose. It argues for the need of an additional factor of reasonableness as defined by John Rawls. We reflect on its articulation with rationality, its role regarding laws and the areas where its presence is crucial to the health and maintenance of a democratic political society. The analysis concludes by justifying the instrumental need of such faculty in the political arena as well as vindicating it as a mandatory civic duty.

The concept of transport capacity and its use in different geomorphic process domains

The notion of sediment-transport capacity has been engrained in geomorphological and related literature for over 50 years, although its earliest roots date back explicitly to Gilbert in fluvial geomorphology in the 1870s and implicitly to eighteenth to nineteenth century developments in engineering. Despite cross fertilization between different process domains, there seem to have been independent inventions of the idea in aeolian geomorphology by Bagnold in the 1930s and in hillslope studies by Ellison in the 1940s. Here we review the invention and development of the idea of transport capacity in the fluvial, aeolian, coastal, hillslope, débris flow, and glacial process domains. As these various developments have occurred, different definitions have been used, which makes it both a difficult concept to test, and one that may lead to poor communications between those working in different domains of geomorphology. We argue that the original relation between the power of a flow and its ability to transport sediment can be challenged for three reasons. First, as sediment becomes entrained in a flow, the nature of the flow changes and so it is unreasonable to link the capacity of the water or wind only to the ability of the fluid to move sediment. Secondly, environmental sediment transport is complicated, and the range of processes involved in most movements means that simple relationships are unlikely to hold, not least because the movement of sediment often changes the substrate, which in turn affects the flow conditions. Thirdly, the inherently stochastic nature of sediment transport means that any capacity relationships do not scale either in time or in space. Consequently, new theories of sediment transport are needed to improve understanding and prediction and to guide measurement and management of all geomorphic systems.

Chinese Men and "Leftover Women" : How do Chinese Men Position Themselves in Relation to the Concept of Labelling Women as "Leftover"?

In recent years there has been a resurgence of gender inequality in China. Today, women are pressured to get married by the state and their social surroundings, as they told if they remain unmarried and have the "three highs"; high age, education and salary, they will become leftovers on the marriage market. Previous research on the concept of labelling women as "leftover" has 4 shown that labelling women as "leftover" can have several different negative impacts. In this thesis, both the theory of masculine hegemony and the theory of symbolic interaction have been used. The concept creates a hegemonic masculinity as it is a normative practice that promotes the subordination of women. However, as the concept is based on the notion that all Chinese men, or at least those of relevant social standing, would find the "three highs" undesirable, it is relevant to see how Chinese men in fact do position themselves in relation to the hegemonic masculinity on an individual level. In symbolic interaction, the concept of gender is created through social construction when people attach special meanings to the sex of a person, a process which is called "doing gender". Therefore symbolic interaction is used to see what special meaning Chinese men attach to women having the "three highs" and masculine hegemony to put their answers into a larger context. If it could be shown that Chinese men do not comply with the hegemonic masculinity, Chinese women would not have to feel obliged to adjust to the hegemonic masculinity and thereby making it easier for them to pursue higher education, high paying jobs and marrying at a later age. However, as this thesis is a qualitative study, and therefore a limited number of data subjects, the generalizability of the result should not be exaggerated. The interviews that were conducted for this thesis showed that the data subjects were familiar with the concept and that they considered it to be natural for there to be women China labelled as "leftover". Nevertheless, in relation to their own marital choices, the data subjects did not attach the negative meaning as set out by the hegemonic masculinity, a result which to some extent was confirmed by the data subjects’ experiences and other control questions. The result is interesting, and enforces Connell and MesserSchmidt’s theory, that even though a hegemonic masculinity is normative, not everyone has to comply with it. As the cornerstone of the concept is that Chinese men find women with the "three highs" undesirable, the result of the study shows that there is a need for the concept to be further examined and questioned.

Art-Map: concept of moving curatorial project and its practical realization in Aveiro

In this dissertation, I present the results of a project which aim was to find out and try an effective model of independent curatorial project executable in small and medium cities in Portugal. The concept of Moving Curatorial Project ARTMAP is a result of theoretical research and reflection about municipal exhibition spaces and possibility of presentation of the contemporary art in these spaces. To test if this curatorial project is realizable and if there are conditions to continue it, a first trial was implemented in Aveiro. A curated international exhibition, entitled “A Poética do Visual" occupied two municipal and two private gallery spaces and brought together 111 artists from 25 different countries. The art event was carried out in collaboration with the Municipality of Aveiro and the University of Aveiro, and involved several private cultural spaces in the city. This first experience showed that there are all conditions for the presentation of contemporary art in small and medium size locations in Portugal, and for this project to be replicated in other regions of the country.

Every nation under heaven: the importance of the biblical concept of nations for contemporary mission practice

Is there a concept of nationhood in the Bible that can provide us with a framework for cross-cultural Christian mission? This thesis argues that current evangelical missiology has accepted too willingly the categories of the secular Enlightenment understanding of ethnicity and nationhood, and that it needs to rethink its understanding of nations from a biblical standpoint. While the pressures of globalisation are seen by some as rapidly eclipsing the nation-state, this thesis will argue that we need to move beyond the narrower secular categories of citizenship, political power and the boundaries of the state to recover a more biblical understanding of nationhood. By reference to Genesis 10-11, Acts 2:1-11 and those passages in the Book of Revelation that discuss the destiny of the nations, it will show that the biblical understanding of nations includes deeper ideas of shared history, culture and language as the essential components of nationhood. It will explain how nations are part of the created order, and explore the impact of the Babel narrative on our understanding of nations in relation to God. It will demonstrate that Pentecost did not reverse the curse of Babel, but served rather to honour the dignity and value of nations and their languages. It will also argue that nations have a destiny in the New Creation according to the Book of Revelation. This biblical concept of nationhood has significant implications in several areas: the development of a public theology; a Christian response to nationalism; the question of how urban mission fits within mission to the nations; and the importance of indigenous languages in cross-cultural mission, especially in the multicultural cities of Europe.

Contradictory male/masculine/men's "I"s: the unwriting of men, and the concept of sex

May I start with two observations? First, men’s relations to feminism are problematic—there is always a gap, a gap between men and feminism; second, the gendering of men and masculinities is now recognised. There are several challenges here. The gender challenge concerns how to move from the presumed “genderlessness” of men towards the gender-consciousness of being a man/men. Another challenge concerns the “public/private,” the disruption of dominant narratives of “I” of men and the masculine “I.” There is also a temporal challenge, of moving away from simple linearity of the “I.” Together, these challenges can be seen as moving away from taken-for-granted “gender power-coherence” towards gender power-consciousness. To address these kinds of question means interrogating the uneven non-equivalences of what it means to be male, a man, masculine. This is not easily reduced to sex or gender. Rather gender/sex, or simply gex, helps to speak of such blurrings.

Prosocial behavior and self-concept of Spanish students of Compulsory Secondary Education

This study analyzed the relationship between prosocial behavior and self-concept dimensions in a sample of 2022 Spanish students (51.1% males) of Compulsory Secondary Education. The prosocial behavior was measured with the Prosocial Behavior scale of the Teenage Inventory of Social Skills (TISS) and the self-concept was measured with the Self-Description Questionnaire-II (SDQ-II). Logistic regression analyses revealed that prosocial behavior is a positive and significant statistically predictor of high scores on the following self-concept dimensions: physical ability, parent relations, same-sex relations, opposite-sex relations, verbal, school, trustworthiness, and self-esteem. Those results were found in males, females and every Compulsory Secondary education year. However, prosocial behavior is not a significant statistically predictor of high scores on physical appearance, math, and emotional stability.

The concept of low glycemic index and glycemic load foods as panacea for type 2 diabetes mellitus; prospects, challenges and solutions.

Background: This article examines the concepts of low glycemic indices (GIs) and glycemic load (GL) foods as key drivers in the dietary management of type 2 diabetes as well as their shortcomings. The controversies arising from the analysis of glycemic index (GI) and GL of foods such as their reproducibility as well as their relevance to the dietary management of type 2 diabetes are also discussed. Methods: Search was conducted in relevant electronic databases such as: Pubmed, Google Scholar, HINARI, the Cochrane library, Popline, LILACS, CINAHL, EMBASE, etc to identify the current status of knowledge regarding the controversies surrounding management of diabetes with low GI and GL foods. Conclusion: This article suggests that in view of discrepancies that surround the results of GI versus GL of foods, any assay on the GI and GL of a food with the aim of recommending the food for the dietary management of type 2 diabetes, could be balanced with glycated hemoglobin assays before they are adopted as useful antidiabetic foods.

A New Concept of Interprofessional Education in Planning Programmes: Reflections on Healthy Urban Planning Project

Although widely debated, some of the defining professional characteristics of planners appear to be competencies in coordination , mediation and multidisciplinary working. Despite this, there is little pedagogical reflection on how interprofessional skills are promoted in planning programmes. This paper reflects on the experience of bringing together undergraduate students from medicine and planning to explore the concept of Healthy Urban Planning in a real life context of an urban motorway extension. This reveals a number of unexpected outcomes of such collaboration and points to the value of promoting interprofessional education, both as a way of increasing interest in some of the key challenges now facing society and in order to induce greater professional reflection amongst our students.

Desenvolvimento do conceito de ângulo: um estudo no 5.ºano de escolaridade

A investigação em curso visa compreender a influência da implementação de um conjunto de tarefas no desenvolvimento do conceito de ângulo em alunos do 5.º ano de escolaridade, procurando responder às seguintes questões: a) Que conceções revelam alunos do 5.º ano de escolaridade relativamente ao conceito de ângulo?; b) Que estratégias utilizam os alunos do 5.º ano de escolaridade na exploração das tarefas utilizadas?; e c) Que aspetos do conceito de ângulo são desenvolvidos pelos alunos através da realização das tarefas propostas? A presente comunicação incide na primeira questão do estudo. Optou-se por uma abordagem metodológica qualitativa de paradigma interpretativo com a modalidade de experiência de ensino. Selecionou-se quatro alunos para constituir o grupo-alvo. Procedeu-se à avaliação diagnóstica das conceções de ângulo dos quatro alunos através da realização, no 1.º Período do ano letivo de 2011/12, de entrevistas clínicas semiestruturadas individuais, gravadas em vídeo. Além das entrevistas, foram usadas, como técnicas de recolha de dados, a observação participante das aulas, videogravadas, bem como a análise de documentos. Para analisar os dados, foram elaboradas categorias analíticas. Os resultados relativos à avaliação diagnóstica evidenciam conceções erradas de ângulo e respetiva amplitude: (a) os ângulos são os lados de polígonos (1 aluna); (b) o comprimento dos segmentos representativos dos lados está relacionado com o tamanho dos ângulos (2 alunos); (c) o comprimento do arco marcando o ângulo está relacionado com o tamanho dos ângulos (3 alunos); (d) nos polígonos côncavos, sãoângulos apenas os de amplitude inferior a 1800 (3 alunos); (e) em figuras que não são polígonos, os ângulos são os espaços entre os segmentos de reta e as linhas curvas (1 aluno); (f) o ângulo é a área entre dois segmentos representativos dos lados (4 alunos); e (g) os ângulos retos são apenas os posicionados na posição usual horizontal/vertical (1 aluna).

Physical interpretation of the correlation between multi-angle spectral data and canopy height

Recent empirical studies have shown that multi-angle spectral data can be useful for predicting canopy height, but the physical reason for this correlation was not understood. We follow the concept of canopy spectral invariants, specifically escape probability, to gain insight into the observed correlation. Airborne Multi-Angle Imaging Spectrometer (AirMISR) and airborne Laser Vegetation Imaging Sensor (LVIS) data acquired during a NASA Terrestrial Ecology Program aircraft campaign underlie our analysis. Two multivariate linear regression models were developed to estimate LVIS height measures from 28 AirMISR multi-angle spectral reflectances and from the spectrally invariant escape probability at 7 AirMISR view angles. Both models achieved nearly the same accuracy, suggesting that canopy spectral invariant theory can explain the observed correlation. We hypothesize that the escape probability is sensitive to the aspect ratio (crown diameter to crown height). The multi-angle spectral data alone therefore may not provide enough information to retrieve canopy height globally.

[recovery: Systematic Review Of A Concept].

The concept of recovery has been described in papers as a state of psychic, physical and social recuperation of day-to-day functions. The scope of this article is to analyze the concepts of the term in different research methodologies and the paradigmatic evolution of the recovery concept. Systematic bibliographical research was conducted in the Pubmed database using the words recovery + schizophrenia limited to freely available full papers published in the previous two years. Nineteen papers were analyzed. The majority of the papers sought associations between characteristic data and recovery; few papers discussed the concept in a way to distinguish it from other words like cure or rehabilitation. Recovery as a state in which people with severe mental illness can feel like the creators of their own itinerary tend to be found in qualitative studies and in bibliographic reviews in which the meaning of recovery is not related to the lack of symptoms and tends to prioritize how participative the life of an individual can be despite the disease. Some quantitative studies detect this conceptual difference. In qualitative research there is an increase in the concept of recovery and in ways of promoting it.

Exploring the potential of functionally graded materials concept for the development of fiber cement

In this study we establish the concept of functionally graded fiber cement. We discuss the use of statistical mixture designs to choose formulations and present ideas for the production of functionally graded fiber cement components for Hatschek machines. The feasibility of producing functionally graded fiber cement by grading PVA fiber content has been experimentally evaluated. Thermogravimetric analysis (TG) was employed to assess fiber distribution profiles and four-point bending tests were applied to evaluate the mechanical performance of both conventional and graded composites. The results show that grading PVA fiber content is an effective way to produce functionally graded fiber cement, which allows for a reduction of the total fiber volume without a significant reduction on modulus of rupture of composite. TG tests were found adequate to assess the fiber content at different points in functionally graded fiber cements. (C) 2009 Elsevier Ltd. All rights reserved.
