The vast diversity of present vegetation and environments that occur throughout South America (12°N to 56°S) is the result of diverse processes that have been operating and interacting at different spatial and temporal scales. Global factors, such as the concentration of CO2 in the atmosphere, may have been significant for high altitude vegetation during times of lower abundance, while lower sea levels of glacial stages potentially opened areas of continental shelf for colonisation during a substantial portion of the Quaternary. Latitudinal variation in orbital forcing has operated on a regional scale. The pace of climate change in the tropics is dominated by precessional oscillations of c. 20 kyr, while the high latitudes of the south are dominated by obliquity oscillations of c. 40 kyr. In particular, seasonal insolation changes forced by precessional oscillations must have had important consequences for the distribution limits of species, with potentially different effects depending on the latitude. The availability of taxa, altitude and human impact, among other events, have locally influenced the environments. Disentangling the different forcing factors of environmental change that operate on different timescales, and understanding the underlying mechanisms leads to considerable challenges for palaeoecologists. The papers in this Special Issue present a selection of palaeoecological studies throughout South America on vegetation changes and other aspects of the environment, providing a window on the possible complexity of the nature of transitions and timings that are potentially available.

The scholarly interest in norm implementation in the area of minority rights protection emerged during the period of the European accession of post-communist societies, which were characterised by persistent cleavage along ethnic lines. These studies have analysed democratic transition of ethnically segmented societies and developed into a broad field that focuses its attention on inter-ethnic relations, the role of history, interstate cooperation and the impact of international organisations on post-communist states' treatment of domestic minorities. All these are usually conducted from a vantage point of the European conditionality research. In our introduction to the special issue we sketch a number of reasons why it is encouraging and indeed, desirable to move beyond the perusal of conditionality into the domain of implementation research.

This article summarizes the key findings from the five mapping case studies presented in this special issue and relates them back to the conceptual, definitional, and theoretical issues presented in the opening article (MacCarthaigh & Roness, 2012). In so doing, the article considers the alternative ways in which organizational change can best be captured, mapped, and explained and the key issues to be considered when conducting such exercises. As well as identifying how the case studies have advanced the possibilities for mapping public sector organizational change over time in a cross-national context and the benefits this offers for other aspects of public administration research, the article identifies some impediments to future research and collaboration in the field and suggests ways to overcome them. © Taylor & Francis Group, LLC.

An analytical survey of how regions have entered into the arguments of the
social sciences serves to highlight the uses and limitations of different understandings of regions and their various theoretical biases. It also provides a way of introducing the articles in the rest of this special issue. It considers how regions have come to be used as a classificatory device across the social sciences, discusses the various meanings given to regions in empirical research, and examines the main philosophical and theoretical controversies that have been sparked by their use. Matching regions to purpose and avoiding a singular conception of ‘region’ that claims to fit all arguments are the main conclusions.

Purpose: This paper aims to provide a brief overview of the global financial crisis (GFC), highlighting its most frightening dimensions, the policy responses and issues around the management of labour during and post-GFC. Further, this paper introduces the five research papers that encompass this special issue. Design/methodology/approach: The papers presented here are early contributions on how the GFC has impacted the management of people. The key areas focused upon include the human resource management responses of multinational enterprises, the response of trade unions, the roles of employee representative bodies and the rationalisation of post-crisis managerial strategies. Findings: The major conclusions of this special issue are that the impact of the GFC was variable across countries and sectors in addition to the process of decision making, the types of decisions made, and the determinants and consequences of those decisions. Originality/value: The papers of the special issue provide some of the first empirical findings on how the GFC has impacted on people management, trade unions and the HR function in different contexts. © Emerald Group Publishing Limited.

This paper presents the design and implementation of a measurement-based QoS and resource management framework, CNQF (Converged Networks’ QoS Management Framework). CNQF is designed to provide unified, scalable QoS control and resource management through the use of a policy-based network
management paradigm. It achieves this via distributed functional entities that are deployed to co-ordinate the resources of the transport network through centralized policy-driven decisions supported by measurement-based control architecture. We present the CNQF architecture, implementation of the
prototype and validation of various inbuilt QoS control mechanisms using real traffic flows on a Linux-based experimental test bed.

Climate change continues to dominate academic work within green/environmental politics. Indeed, there appears to be almost an inverse relationship between the lack of political leadership on tackling climate change and the growth in ever more sophisticated academic analyses of this complex and multifaceted problem. There is an increasing disjunction between the growth in our knowledge and understanding of the ethical, political, economic, sociological, cultural, and psychological aspects of climate change and the lack of political achievement in putting in place clear and binding targets, an agreed decarbonisation roadmap, and associated regulatory and policy instruments with enforcement. This gap might be taken as evidence that we do not need more reports on climate change. To quote that most unlikely of green politicians, Arnold Schwarzenegger, former Governor of California: ‘The debate is over. We know the science. We see the threat. And we know that the time for action is now’ (California Energy Commission 2007, p. 1). This special issue focuses on a variety of ways in which climate change is conceptualised in normative political and ethical theory, and addressed in policy and regulations.

Oxidation of NADH in the mitochondrial matrix of aerobic cells is catalysed by mitochondrial complex I. The regulation of this mitochondrial enzyme is not completely understood. An interesting characteristic of complex I from some organisms is the ability to adopt two distinct states: the so-called catalytically active (A) and the de-active, dormant state (D). The A-form in situ can undergo de-activation when the activity of the respiratory chain is limited (i.e. in the absence of oxygen). The mechanisms and driving force behind the A/D transition of the enzyme are currently unknown, but several subunits are most likely involved in the conformational rearrangements: the accessory subunit 39 kDa (NDUFA9) and the mitochondrially encoded subunits, ND3 and ND1. These three subunits are located in the region of the quinone binding site. The A/D transition could represent an intrinsic mechanism which provides a fast response of the mitochondrial respiratory chain to oxygen deprivation. The physiological role of the accumulation of the D-form in anoxia is most probably to protect mitochondria from ROS generation due to the rapid burst of respiration following reoxygenation. The de-activation rate varies in different tissues and can be modulated by the temperature, the presence of free fatty acids and divalent cations, the NAD/NADH ratio in the matrix, the presence of nitric oxide and oxygen availability. Cysteine-39 of the ND3 subunit, exposed in the D-form, is susceptible to covalent modification by nitrosothiols, ROS and RNS. The D-form in situ could react with natural effectors in mitochondria or with pharmacological agents. Therefore the modulation of the re-activation rate of complex I could be a way to ameliorate the ischaemia/reperfusion damage.
