Integration of decision support systems to improve decision support performance

Decision support system (DSS) is a well-established research and development area. Traditional isolated, stand-alone DSS has been recently facing new challenges. In order to improve the performance of DSS to meet the challenges, research has been actively carried out to develop integrated decision support systems (IDSS). This paper reviews the current research efforts with regard to the development of IDSS. The focus of the paper is on the integration aspect for IDSS through multiple perspectives, and the technologies that support this integration. More than 100 papers and software systems are discussed. Current research efforts and the development status of IDSS are explained, compared and classified. In addition, future trends and challenges in integration are outlined. The paper concludes that by addressing integration, better support will be provided to decision makers, with the expectation of both better decisions and improved decision making processes

Exploring ‘Gender-ICT-Climate Change’ Nexus in Development: from Digital Divide to Digital Empowerment

How gender influences the effectiveness of information and communication technologies (ICTs) in tackling climate change is under-researched. Gender is social expectations and stereotypes of how men, women, boys and girls, should behave in society. Gender enables some groups of men and women to get access to ICTs, whilst constraining others from doing so. Different control over ICTs, built on unequal power relationships, affects how poor people adapt to the changing climate and respond to climate-related disasters. Conceptually, this paper explains why, and how, women are more constrained than men from using ICTs in tackling climate change. In term of assets, compared to men, women have less access to technology, to information, to finance, and are more deprived of land rights. Women are more institutionally-constrained than men. With regard to social structures, women are excluded from decision-making in policy design and resource allocation. They are less represented in formal decision-making bodies, such as the Clean Development Mechanism (CDM) and the Reducing Emissions from Deforestation and Forest Degradation (REDD) initiative. In addressing these limitations, this paper makes four digital empowerment proposals in an attempt to make 'ICT-climate change' interventions more gender-sensitive: (1) Contextualise gender mainstreaming: gender mainstreaming helps integrate gender analysis into ICT policies. It acknowledges that men and women perceive and receive information differently, and that this requires diverse approaches to adaptation. However, the attempt to re-position women and girls as 'eco-carers' is problematic because this fails to capture their protective, as well as their destructive, role in relation to natural resources. Without addressing the unequal power relations between women and girls, e-adaptive practices can also help reproduce the inter-generational equalities. (2) Strengthen governance: crafting new and reforming old, institutional arrangements is essential to improve gender inclusion. Women-only interventions are sometimes necessary to empower previously-excluded women to engage in ICT-related decisions. However, poor and powerless men should also have their say in climate change policies. (3) Develop gender-sensitive funding mechanisms: securing adequate funding to support ICT interventions is crucial to gender empowerment. Yet, targeting women by micro-credit projects risk putting an additional financial burden on them, and that needs serious re-consideration. (4) Recognise agency-structure dynamics: women are active agents, but they are socially constrained from engaging in ICT-related decisions. Women's preferences, institutional arrangements and politics need to be taken into account in order to tackle digital exclusion. These four proposals will be useful for development agencies, governments and NGOs seeking to improve the gendered outcomes from use of ICTs in response to climate change

Open semantic service networks

Online service marketplaces will soon be part of the economy to scale the provision of specialized multi-party services through automation and standardization. Current research, such as the *-USDL service description language family, is already defining the basic building blocks to model the next generation of business services. Nonetheless, the developments being made do not target to interconnect services via service relationships. Without the concept of relationship, marketplaces will be seen as mere functional silos containing service descriptions. Yet, in real economies, all services are related and connected. Therefore, to address this gap we introduce the concept of open semantic service network (OSSN), concerned with the establishment of rich relationships between services. These networks will provide valuable knowledge on the global service economy, which can be exploited for many socio-economic and scientific purposes such as service network analysis, management, and control
