Context dependent revocation in delegated XACML

The XACML standard defines an XML based language for defining access control policies and a related processing model. Recent work aims to add delegation to XACML in order to express the right to administrate XACML policies within XACML itself. The delegation profile draft explains how to validate the right to issue a policy, but there are no provisions for removing a policy. This paper proposes a revocation model for delegated XACML. A novel feature of this model is that whether a revocation is valid or not, depends not only on who issued the revocation, but also on the context in which an attempt to use the revoked policy is done

Financial decentralization in Ukraine: prerequisites, problems, prospects

The purpose of the article is to analyze the prerequisites, advantages, problems and prospects for the development of the processes of financial decentralization in Ukraine. Initially, the article reveals the features of the federal and unitary arrangements of states. As research has shown, the principles of fiscal federalism have been increasingly used by unitary states. The legislative and normative legal acts regulating the implementation of the decentralization policy in Ukraine are justified and given. Characteristics of the formation of new structures, such as: united territorial societies and their sources of financing are characterized. Changes in incomes in local budgets as a result of decentralization are analyzed, and their significant growth is observed. The mechanism of horizontal leveling of the tax ability of territories has been developed, which helps to remove imbalances and unevenness, most of the budgets of Ukraine are recipients of budgetary funds, since they receive a basic subsidy. The influence of the development of information technologies on entrepreneurial activity in small towns and villages is determined. Information technology is a tool of points of growth of territories. Decentralization will not gradually increase due to urbanization processes, but will be accompanied by new development mechanisms, where the labor force and the means of production will unite and help create a qualitatively new environment

Value Attainment, Orientations, and Quality-Based Profile of the Local Political Elites in East-Central Europe. Evidence from Four Towns

The present paper is an attempt at examining the value configuration and the socio-demographical profiles of the local political elites in four countries of East-Central Europe: Romania, the Czech Republic, Bulgaria, and Poland. The treatment is a comparative one, predominantly descriptive and exploratory, and employs, as a research method, the case-study, being a quite circumscribed endeavor. The cases focus on the members of the Municipal/Local Council in four towns similar in terms of demography and developmental strategies (i.e. small-to-medium sized communities of around 35,000 inhabitants, with economies largely based on food industry and commercial activities): Tecuci (Galați county, Romania), Česká Lípa (Liberec region, Czech Republic), Targovishte (Targovishte province, Bulgaria), and Oleśnica (Lower Silesia province, Poland). Hypothesizing that the local elites of the former Sovietized Erurope tend to differ in outlook, priorities, and value attainment, as compared to their Western counterparts, the paper considers the former’s attitudes and perspectives in regard to seven values: a series of values customarily connected with the concept of ‘democracy’ (i.e. citizen participation, political conflict, gradual change, economic equality), state intervention in economy, decentralization and increased local autonomy, cultural-geographical self-identification. The study uses, as well, five models of value attainment in what concerns the ‘ideal portrait’ of the local councilor (Putnam 1976): ethical, pragmatic, technocratic, political, and gender. According to the results of a study applying a standard written questionnaire among the local councilors of the three communities in the period December 2010-February 2013, the paper distinguishes among three corresponding types of local elites: (1) ‘predominantly elitistic,’ (2) ‘democratic elitist,’ and (3) ‘predominantly democratic,’ following two types of explanation accounting for the differences among the four cases: the legacy of the defunct regime and the degree of administrative decentralization

CamFlow: Managed Data-sharing for Cloud Services

A model of cloud services is emerging whereby a few trusted providers manage the underlying hardware and communications whereas many companies build on this infrastructure to offer higher level, cloud-hosted PaaS services and/or SaaS applications. From the start, strong isolation between cloud tenants was seen to be of paramount importance, provided first by virtual machines (VM) and later by containers, which share the operating system (OS) kernel. Increasingly it is the case that applications also require facilities to effect isolation and protection of data managed by those applications. They also require flexible data sharing with other applications, often across the traditional cloud-isolation boundaries; for example, when government provides many related services for its citizens on a common platform. Similar considerations apply to the end-users of applications. But in particular, the incorporation of cloud services within `Internet of Things' architectures is driving the requirements for both protection and cross-application data sharing. These concerns relate to the management of data. Traditional access control is application and principal/role specific, applied at policy enforcement points, after which there is no subsequent control over where data flows; a crucial issue once data has left its owner's control by cloud-hosted applications and within cloud-services. Information Flow Control (IFC), in addition, offers system-wide, end-to-end, flow control based on the properties of the data. We discuss the potential of cloud-deployed IFC for enforcing owners' dataflow policy with regard to protection and sharing, as well as safeguarding against malicious or buggy software. In addition, the audit log associated with IFC provides transparency, giving configurable system-wide visibility over data flows. [...]Comment: 14 pages, 8 figure

Role and Discipline Relationships in a Transdisciplinary Biomedical Team: Structuration, Values Override and Context Scaffolding

Though accepted that "team science" is needed to tackle and conquer the health problems that are plaguing our society significant empirical evidence of team mechanisms and functional dynamics is still lacking in abundance. Through grounded methods the relationship between scientific disciplines and team roles was observed in a United States National Institutes of Health-funded (NIH) research consortium. Interviews and the Organizational Culture Assessment Instrument (OCAI) were employed.. Findings show strong role and discipline idiosyncrasies that when viewed separately provide different insights into team functioning and change receptivity. When considered simultaneously, value-latent characteristics emerged showing self-perceived contributions to the team. This micro/meso analysis suggests that individual participation in team level interactions can inform the structuration of roles and disciplines in an attempt to tackle macro level problems.Comment: Presented at COINs13 Conference, Chile, 2013 (arxiv:1308.1028

Aid Financing of Global Public Goods: an Update

The paper compares different aggregates of aid financed global public goods and detects the presence, for the period 1995-2006, of the substitution effect between these aggregates and traditional aid that was found by former studies for earlier periods. A second focus of the paper is on the differences in the importance that donors attach to the various types of global public goods, trying to detect regular patterns in their choices of financing. Statistical regularities, representative of common historical, social, cultural factors, for groups of countries (Anglo-Saxon, Northern European and Central European) give rise to the existence of a certain clusterized homogeneity in global public goods financing. Potential explanatory variables are examined in a panel analysis, which reveals the dominance of the donors’ wealth, preferences for public goods and public finance constraints in the decision of aid funding of global public goods. Finally, there is evidence that some global public goods with weakest-link technologies have become increasingly important at the global level. The increase in their financing through aid flows could be explained by the rich countries’ fear of an insufficient provision by poor countries, which, increasingly, cannot afford to pay for them: rich countries are therefore stepping in to avoid sub-optimal levels of provision, as already foreseen by Sandler (1998).Foreign aid, Global public goods

Dynamics of the Corruption Eradication in Indonesia

The paper discusses an important aspect of the complexity of corruption eradication in Indonesia. Corruption eradication is practically not merely about law enforcement, but also related to social, economic, and political aspects of the nation. By extracting the data from national news media and implement models describing the sentiment relations among political actors, the connection between balance of the sentiment among political elites and the critical levels of the investigation and law enforcement is apparently demonstrated. The focus group discussions among experts, practitioners, and social activists confirm the model

CONFLICT, DECENTRALISATION AND LOCAL GOVERNANCE IN COLOMBIA, 1974-2004

The objective of this paper is to determine the variables that explain the geographical expansion and armed activity of Colombian irregular groups since the mid seventies, taking into account the role of the political, fiscal and budgetary decentralization and its effects over local governance. This period of Colombian history (1974-2004) has been graved by strong economic, social and institutional changes that have deepened particularly since the decentralization process of the mid eighties. In fact, this paper states that decentralization process transformed the conflict into a dispute over the local power, intensifying the use of violence in order to appropriate part of the public goods and resources, interfere the political process and consolidate the group´s territorial control. The analysis of the illegal group´s early activity (1974-1982) shows that the use of violence is explained by grievances such as poverty or inequality. However, subsequent years reveal deep changes in the illegal group´s strategic procedures in which the decentralization process have given them incentives to control the local governments by using violence (greed). The results demonstrate a strong and significant relationship between the intensification of the armed conflict and the greater political, budgetary and fiscal autonomy of local governments. In fact, the presence of local resources such as royalties and taxes triggers violence against politicians being more intense in the municipalities where the actions of the illegal groups are higher.Armed conflict, Violence, Decentralization, Local governance, Spatial Econometrics
