WATER DIFFUSION COEFFICIENT AND MODELING OF WATER UPTAKE IN PACKAGED YERBA MATE

JOURNAL OF FOOD PROCESSING AND PRESERVATION, Issue 4 2007
LAURA A. RAMALLO
ABSTRACT Effective water diffusion coefficient (Deff) was determined from the kinetics of moisture gain in a yerba mate bed. A value of 1.5 × 10,9 ± 0.4 × 10,9 m2/s was obtained at 40C and 90% relative humidity, by fitting experimental data to the series solution of Fick's second law. A model was developed to predict moisture profile and water uptake in packaged yerba mate. In order to simulate moisture gain in the packaged food, the model considers that the global process of humidity gain is controlled by combined mechanisms of package permeability, product sorption balances and water diffusion within the food bed. The explicit finite difference method was used to numerically solve the resulting equations. The validity of the model was tested by comparing predicted and experimental moisture profiles for high (WVTR , 20 g/m2/day) and low (WVTR , 400 g/m2/day) barrier packages. The model was found to adequately predict the profile of moisture content. [source]


The demographic transition revisited as a global process

POPULATION, SPACE AND PLACE (PREVIOUSLY:-INT JOURNAL OF POPULATION GEOGRAPHY), Issue 1 2004
David S. Reher
Abstract With dramatic declines in fertility taking place throughout the world, it is increasingly important to understand the demographic transition as a global process. While this universality was a cornerstone of classic transition theories, for many decades it was largely neglected by experts because fertility in the developing world did not seem to follow the expected pattern. When comparing earlier and more recent transition experiences, important similarities and disparities can be seen. Everywhere mortality decline appears to have played a central role for fertility decline. The differences in the timing of the response of fertility to mortality decline, with very small gaps historically and prolonged ones in more recent transitions, plus the much more rapid decline in vital rates in many developing countries, constitute an important challenge to any general explanation of the process. The specific characteristics of recent transitions have led to decades of higher population growth rates, and promise to give way to much more rapid dynamics of population ageing in many countries. This may limit the ability of newcomers to take full advantage of the demographic transition for the social and economic modernisation of their societies. Copyright © 2004 John Wiley & Sons, Ltd.

The Institutional Context of Market Ideology: A Comparative Analysis of the Values and Perceptions of Local Government CEOs in 14 OECD Countries

PUBLIC ADMINISTRATION, Issue 2 2004
Morten Balle Hansen
During recent decades, various versions of market practices have, in most nation states, diffused into the public sector. We analyse variations in the adoption of market ideologies and examine plausible explanations for these variations. Four managerial ideal types are constructed, based on their attitudes towards two dimensions of market ideology. Managerial attitudes and perceptions are conceived as embedded in a global process of diffusion highly affected by varying institutional preconditions. The impact of five types of institutional contexts is examined: the national context, the organizational context, the context of interaction, the context of socialization and the norms of the manager.

Progressive brain changes in schizophrenia: a 1-year follow-up study of diffusion tensor imaging

ACTA NEUROPSYCHIATRICA, Issue 6 2009
Miho Ota
Objective: Recent cross-sectional studies suggest that brain changes in schizophrenia are progressive during the course of the disorder. However, it remains unknown whether this is a global process or whether some brain areas are affected to a greater degree. The aim of this study was to examine the longitudinal brain changes in patients with chronic older schizophrenia by magnetic resonance imaging (MRI). Methods: Three-dimensional (3D) T1-weighted and diffusion tensor (DT) MRI were performed twice on each of 16 chronic older schizophrenia patients (mean age = 58.1 ± 6.7 years ) with an interval of 1 year between imaging sessions. To clarify the longitudinal morphological and white matter changes, volume data and normalised diffusion tensor imaging (DTI) metrics were compared between the first and follow-up studies using a paired t -test. Results: Focal cortical volume loss was observed in the left prefrontal lobe and anterior cingulate on volumetric study. In addition, DTI metrics changed significantly at the bilateral posterior superior temporal lobes, left insula, genu of the corpus callosum and anterior cingulate. Conclusion: There are ongoing changes in the brains of schizophrenic patients during the course of the illness. Discrepancies between volume data and DTI metrics may indicate that the pattern of progressive brain changes varies according to brain region. [source]


In the Mirror: The Legitimation Work of Globalization

LAW & SOCIAL INQUIRY, Issue 4 2002
Susan Bibler Coutin
This essay examines the legitimation work of globalization by bringing into dialogue the authors' research on immigration, finance, and intercountryadoption. It is concerned with the practices that produce, define, and preclude both movement and connection, such as "naturalizing" some border crossings while criminalizing others; denying the histories and policies that allow some parents to "choose" babies while others must abandon them; and challenging the practices through which small states tweak transnational financial systems while allowing multinational corporations privileges denied small states. Legitimation work (re)configures jurisdictionality, transparency, and sovereignty,the constructs on which debates over globalization's consequences hinge. Examining how these constructs order, include, and exclude persons, goods, and practices sheds light on the boundaries, slippages, and connections between the legitimate and the illegitimate within global processes.

Restructuring Governance of New Zealand Seaports: Geographical Impacts of Corporatisation

NEW ZEALAND GEOGRAPHER, Issue 2 2004
Ali Memon
ABSTRACT This study examines the rationales for and geographical outcomes of the post 1988 changes in port governance in New Zealand and their implications from a policy perspective. The study offers insights into the interrelationship between global processes and local places in the context of economic deregulation, a devolved infrastructure planning mandate and intra-industry competitive dynamics. A trend towards port concentration consequent on globalisation has been long recognised in the international literature. In New Zealand, the trend towards port concentration can be described as selective, limited primarily to import trade while export trade is more dispersed. This new port geography is part of wider political and socio-economic development geographies of the national and global hinterlands and forelands these ports interact with. [source]


LIVING A DISTRIBUTED LIFE: MULTILOCALITY AND WORKING AT A DISTANCE

ANNALS OF ANTHROPOLOGICAL PRACTICE, Issue 1 2008
Brigitte Jordan
In the last few years, new collaboration and communication technologies have led to a deterritorialization of work, allowing for the rise of new work- and lifestyles. In this article, I use my own transition from the life of a corporate researcher to that of a multilocal mobile consultant for tracking some of the patterns I see in a changing cultural and economic environment where work and workers are no longer tied to a specific place of work. My main interest lies in identifying some of the behavioral shifts that are happening as people are caught up in and attempt to deal with this changing cultural landscape. Writing as a knowledge worker who now moves regularly from a work,home place in the Silicon Valley of California to another in the tropical lowlands of Costa Rica, I use my personal transition as a lens through which to trace new, emergent patterns of behavior, of values, and of social conventions. I assess the stresses and joys, the upsides and downsides, the challenges and rewards of this work- and lifestyle and identify strategies for making such a life successful and rewarding. Throughout, there emerges an awareness of the ways in which the personal patterns described reflect wider trends and cumulatively illustrate global transformation of workscapes and lifescapes. These types of local patterns in fact constitute the on-the-ground material reality of global processes that initiate and sustain widespread culture change and emergent societal transformations.

Negotiating Individualist and Collectivist Futures: Emerging Subjectivities and Social Forms in Papua New Guinean High Schools

ANTHROPOLOGY & EDUCATION QUARTERLY, Issue 2 2003
Assistant Professor Peter Demerath
This article explains the academic disengagement of a critical mass of high school students in Manus Province, Papua New Guinea, as resulting in part from emerging personal subjectivities and new social networks. Based on a year of ethnographic research in 1994,95, the article describes the authority these young people attributed to their own perceptions of the limited opportunity structures facing them and to the idealized village-based egalitarian student identity being circulated through peer networks. As such, it illuminates the educational implications of youth culture, and demonstrates how local and global processes are mediated through the social fields of high schools. [source]


Looking Forward by Looking Back: May Day Protests in London and the Strategic Significance of the Urban

ANTIPODE, Issue 4 2004
Justus Uitermark
This paper deals with the question of how oppositional movements can adapt their protest strategies to meet recent socio-spatial transformations. The work of Lefebvre provides several clues as to how an alternative discourse and appropriation of space could be incorporated in such protest strategies. One of the central themes in Lefebvre's work is that the appearances, forms and functions of urban space are constitutive elements of contemporary capitalism and thus that an alternative narrative of urban space can challenge or undermine dominant modes of thinking. What exactly constitutes the "right" kind of alternative discourse or narrative is a matter of both theoretical and practical consideration. The paper analyses one case: the May Day protests in London in 2001, in which a protest group, the Wombles, managed to integrate theoretical insights into their discourse and practice in a highly innovative manner. Since cities, and global cities in particular, play an ever more important role in maintaining the consumption as well as production practices of global capitalism; they potentially constitute local sites where global processes can be identified and criticised. It is shown that the Wombles effectively made use of these possibilities and appropriated the symbolic resources concentrated in London to exercise a "lived critique" of global capitalism. Since the Wombles capitalised on trends that have not yet ended, their strategies show a way forward for future anti-capitalist protests. [source]
