Language change in socially structured populations

Language contact is a significant external social factor that impacts on the change in natural languages over time. In some circumstances this corresponds to language competition, in which individuals in a population choose one language over another based on their social interactions. We investigated the dynamics of language change in two initially separate populations of agents that were then mixed with levels of influence determined by the social classes of the two populations, with 16 different combinations tested. As expected, the study found that how the communities interact with each other impacts on the communal language developed. However, it was also found that the acquisition of new words was substantial even with limited interaction between populations and low levels of influence, and that comprehension could be well established across language groups even when production of words from the other language group was low.

Balancing entertainment and behaviour value: M-games as a social marketing agent of change

In a marketplace where millions of dollars are spent on the design of mobile games (m-games), social marketers are now using this technology as a tool for behaviour change. Despite high expenditure by governments and non-profits on social marketing m-games, little is known about their effectiveness in terms of creating value. Value creation has been demonstrated to have an important impact on satisfaction and behaviour. This paper reports the results of a qualitative study involving four focus groups with 23 participants to reveal two categories of experiential value, entertainment and behaviour. Additionally, it was discovered that entertainment could be characterised by amusement and social value dimensions. Whereas, behaviour could be made up of information, simulation and distraction value dimensions. The categories of value, as well as the dimensions of information, simulation and distraction are entirely new to the social marketing literature and thus represents a unique contribution to social marketing.

Fast and slow climate responses to CO2 and solar forcing: A linear multivariate regression model characterizing transient climate change

Climate change in response to a change in external forcing can be understood in terms of fast response to the imposed forcing and slow feedback associated with surface temperature change. Previous studies have investigated the characteristics of fast response and slow feedback for different forcing agents. Here we examine to what extent that fast response and slow feedback derived from time-mean results of climate model simulations can be used to infer total climate change. To achieve this goal, we develop a multivariate regression model of climate change, in which the change in a climate variable is represented by a linear combination of its sensitivity to CO2 forcing, solar forcing, and change in global mean surface temperature. We derive the parameters of the regression model using time-mean results from a set of HadCM3L climate model step-forcing simulations, and then use the regression model to emulate HadCM3L-simulated transient climate change. Our results show that the regression model emulates well HadCM3L-simulated temporal evolution and spatial distribution of climate change, including surface temperature, precipitation, runoff, soil moisture, cloudiness, and radiative fluxes under transient CO2 and/or solar forcing scenarios. Our findings suggest that temporal and spatial patterns of total change for the climate variables considered here can be represented well by the sum of fast response and slow feedback. Furthermore, by using a simple 1-D heat-diffusion climate model, we show that the temporal and spatial characteristics of climate change under transient forcing scenarios can be emulated well using information from step-forcing simulations alone.

Functional gold nanoparticle-peptide complexes as cell-targeting agents

In this paper, we report a novel approach using peptide CALNN and its derivative CALNNGGRRRRRRRR (CALNNR(8)) to functionalize gold nanoparticles for intracellular component targeting. The translocation is effected by the nanoparticle diameter and CALNNR8 surface coverage. The intracellular distributions of the complexes are change from the cellular nucleus to the endoplasmic reticulum by increasing the density of CALNNR8 at a constant nanoparticle diameter. Additionally, increasing the nanoparticle diameter at a constant density of CALNNR8 leads to less cellular internalization.

Diasporic Agents and Trans-Asian Flows in the Making of Asian Modernity: The Case of Thailand

How do our everyday actions shape and transform the world economy? This volume of original essays argues that current scholarship in international political economy (IPE) is too highly focused on powerful states and large international institutions. The contributors examine specific forms of â everyday' actions to demonstrate how small-scale actors and their decisions can shape the global economy. They analyse a range of seemingly ordinary or subordinate actors, including peasants, working classes and trade unions, lower-middle and middle classes, female migrant labourers and Eastern diasporas, and examine how they have agency in transforming their political and economic environments. This book offers a novel way of thinking about everyday forms of change across a range of topical issues including globalisation, international finance, trade, taxation, consumerism, labour rights and regimes. It will appeal to students and scholars of politics, international relations, political economy and sociology.

Regulatory regime change in Turkish banks:Reactive or proactive?

This paper examines the positive contributions made toward restructuring the regulatory framework of Turkey's banking and financial sectors prior to and post the 2000–2001 financial crisis. Drawing on a framework initially developed by Onis and Senses, 2007 and Onis and Senses, 2009 and further referred to by Onis, 2009 and Onis, 2010 it argues that financial reforms undertaken by the Turkish government would not have been successful without the strong support of domestic coalitions. While the external pressures put on the Turkish government from the International Monetary Fund, The World Bank and the European Union for financial reforms were necessary to kick start the reforms as a reactive process, these pressures on their own may have served only the interests of financial business elites at the expense of the broader stakeholders. Empirical data for the study was collected from documentary analysis of key financial institutions and interviews with twenty major Turkish regulatory agents and other stakeholders. The paper then discusses how the perceptions of these stakeholders are embodied into, and have influenced, regulatory regime change in Turkey from a reactive state to a more proactive one.

Climate Change Mitigation and Intergenerational Justice

Existing climate change mitigation policies are particularly concerned with the reconciliation of two seemingly conflicting aims: environmental protection and economic efficiency. The normative principles underlying these policies meanwhile focus on two central ideas: fair burden-sharing and agents' responsibility. However, both existing policy instruments and their supporting philosophical principles are highly problematic in terms of intergenerational justice and truly effective climate change mitigation. Three competing conceptions for allocating and distributing the burdens of climate change mitigation (cap-and-trade schemes, carbon emission taxes, and personal ecological space quotas) and their compatibility with principles of intra- and intergenerational justice are analysed and evaluated. None of the proposed instruments is able to satisfy the demands of effective mitigation and egalitarian justice on its own, which suggests that existing proposals for the distribution of emission rights and climate change-related costs need to be supported by a thicker account of intergenerational justice.

Varieties of Economic Crisis, Varieties of Ideational Change: How and Why Macroeconomic Policy and Financial Regulation Differ

One of the principal tasks facing post-crash academic political economy is to analyse patterns of ideational change and the conditions that produce such change. What has been missing from the existing literature on ideational change at times of crises however, is a sense of how processes of persuasive struggle, and how the success of those ‘norm entrepreneurs’ arguing for ideational change is shaped by two contextual variables: the most immediate material symptoms and problems that a crisis displays (the variety of crisis); and the institutional character of the policy subsystem that agents have to operate within to affect change. Introducing these two variables into our accounts of persuasive struggle and ideational change enables us to deepen our understanding of the dynamics of ideational change at times of crisis. The article identifies that a quite rapid and radical intellectual change has been evident in the field of financial regulation in the form of an embrace of a macroprudential frame. In contrast in the field of macroeconomic policy - both monetary and fiscal policy, many pre-crash beliefs remain prominent, there is evidence of ideational stickiness and inertia, and despite some policy experimentation, overarching policy frameworks and their rationales have not been overhauled. The article applies Peter Hall’s framework of three orders of policy changes to help illuminate and explain the variation in patterns of change in the fields of financial regulation and macroeconomic policy since the financial crash of 2008. The different patterns of ideational change in macroeconomic policy and financial regulation in the post-crash period can be explained by timing and variety of crisis; sequencing of policy change; and institutional political differences between micro policy sub systems and macro policy systems.

Tracking Change in Northern Ireland Policing: Temporal Phases and Key Themes

Purpose
– The purpose of this paper is to explore and explain the change process in Northern Ireland policing through an analysis of temporally bracketed change phases and key change delivery themes ranging from 1996 to 2012.

Design/methodology/approach
– The research approach adopted is process based, longitudinal and multi-method, utilising “temporal bracketing” to determine phases of change and conjunctural reasoning to unravel the systematic factors interacting over time, within the case.

Findings
– The paper identifies and temporally brackets four phases of change: “Tipping point”; “Implementation, Symbolic Modification and Resistance”; “Power Assisted Steering”; and “A Return to Turbulence”, identifies four themes that emerge from RUC-PSNI experience: the role of adaptive leadership; pace and sequencing of change implementation; sufficient resourcing; and the impact of external agents acting as boundary spanners, and comments on the prominence of these themes through the phases. The paper goes on to reflect upon how these phases and themes inform our understanding of organisational change within policing organisations generally and within politically pressurised transition processes.

Originality/value
– The contribution of the paper lies in the documentation of an almost unique organisational case in an environmentally forced change process. In this it contains lessons for other organisations facing similar, if less extreme challenges and presents an example of intense change analysed longitudinally.

Belief change with noisy sensing in the situation calculus

Situation calculus has been applied widely in arti?cial intelligence to model and reason about actions and changes in dynamic systems. Since actions carried out by agents will cause constant changes of the agents’ beliefs, how to manage
these changes is a very important issue. Shapiro et al. [22] is one of the studies that considered this issue. However, in this framework, the problem of noisy sensing, which often presents in real-world applications, is not considered. As a
consequence, noisy sensing actions in this framework will lead to an agent facing inconsistent situation and subsequently the agent cannot proceed further. In this paper, we investigate how noisy sensing actions can be handled in iterated
belief change within the situation calculus formalism. We extend the framework proposed in [22] with the capability of managing noisy sensings. We demonstrate that an agent can still detect the actual situation when the ratio of noisy sensing actions vs. accurate sensing actions is limited. We prove that our framework subsumes the iterated belief change strategy in [22] when all sensing actions are accurate. Furthermore, we prove that our framework can adequately handle belief introspection, mistaken beliefs, belief revision and belief update even with noisy sensing, as done in [22] with accurate sensing actions only.

La reconnaissance entre échange, pouvoirs et institutions. Le républicanisme de Philip Pettit.

Cet article propose une lecture critique de l’approche néorépublicaine de la reconnaissance et du projet d’une économie de l’estime, développé par Ph. Pettit et G. Brennan. Il vise à montrer en quoi la conception de la reconnaissance qui est celle de ce dernier est trop étroite, dans la mesure où elle va de pair avec une analyse insuffisante des conditions de la visibilité sociale des performances et capacités des agents, ainsi que de la manière dont les luttes de reconnaissance peuvent contribuer à une telle visibilité. Ce texte montre ainsi en quoi il convient d’élargir la conception néorépublicaine de la reconnaissance. Il vise aussi à dégager les limites du projet d’une économie de l’estime, en montrant ses lacunes eu égard à une réflexion suffisante sur les conditions d’un pluralisme des standards d’estime.

Régulations homéostatiques cardiovasculaires suite à une transfusion par échange avec du sang hyperagrégeant chez le rat

Dans le but de vérifier l’impact d’un changement soudain dans l’agrégation érythrocytaire sur certains paramètres cardiovasculaires, une transfusion par échange sanguin du tiers du volume a été effectuée avec du sang hyperagrégeant chez le rat de souche Brown Norway. La pression caudale, le volume cardiaque systolique, la fraction d’éjection, le débit cardiaque, le rythme cardiaque et la résistance périphérique à l’écoulement sanguin ont été observés non-intrusivement sur 19 jours suite à la transfusion. Les rats ont été sacrifiés plus d’un mois suivant la transfusion et une étude ex vivo de la réponse à deux agents dilatateurs (l’acétylcholine et le nitroprussiate de sodium) a été menée sur les artérioles mésentériques. Des variations des paramètres cardiovasculaires, soit le débit, le volume systolique et la résistance périphérique, ont été remarquées dans les trois premiers jours posttransfusion. Une résistance du muscle vasculaire lisse au monoxyde d’azote a été notée chez les rats transfusés au sang hyperagrégeant alors qu’aucune dysfonction endothéliale n’était apparente en réponse à l’acétylcholine.
