The silent victims of humanitarian crises and livelihood (in)security: a case study among migrants in two Chadian towns

Once a humanitarian disaster receives coverage in the global media, the international community usually mobilises to reduce the most severe consequences. However people in Chad are experiencing endemic crises that are detached from speci!c triggers, and they are not receiving any international assistance to help relieve the hardships they face. "is study involves 111 migrant households from central Chad that, as a result of war and drought, have lost everything and now have to live in squatter areas of N’Djamena and Mongo, facing uncertainty and threats while negotiating their livelihoods. Qualitative and quantitative methods have been combined in this study to reveal the intriguing story of their daily lives in the face of complex and endemic crises. Anthropometric and health data were generated to determine the nutritional status of mothers and their children under !ve. Life histories, in-depth interviews and participatory observation allowed the researchers to capture the negotiation strategies they use to access food and shelter, their experiences of food insecurity and sanitary vulnerability, and the consequences these have on daily life. Results indicate that 62% of households were female headed, there were high rates of acute (40-50%) and chronic (35-40%) malnutrition and 46% of the mothers were underweight and anaemic. Infant mortality rates were also high at 30%-42% and 97% of the children had had incomplete or no vaccinations. No households had access to clean water, sanitation or public-health services. Endemic corruption and abuse by the authorities were identi!ed as major sources of day-to-day insecurity. "ese migrants were not expecting any improvement in their livelihoods in the foreseeable future and saw these miserable conditions as norma

Measuring Symbol and Icon Characteristics: Norms for Concreteness, Complexity, Meaningfulness, Familiarity, and Semantic Distance for 239 Symbols

This paper provides rating norms for a set of symbols and icons selected from a wide variety of sources. These ratings enable the effects of symbol characteristics on user performance to be systematically investigated. The symbol characteristics that have been quantified are considered to be of central relevance to symbol usability research and include concreteness, complexity, meaningfulness, familiarity, and semantic distance. The interrelationships between each of these dimensions is examined and the importance of using normative ratings for experimental research is discussed

Ecology and power in the periphery of Maasina : the case of the Hayre in the nineteenth century

This article explores political tensions between successive nineteenth-century rulers of the inland delta of the Niger in central Mali (the Fulbe Diina of Hamdullahi and the Futanke successors of al-Hajj Umar) and the pastoral interests of the Fulbe chiefdoms on their eastern periphery, in a region known as the Hayre. A close study of changing forms of local governance and natural resource management demonstrates that although different strategies were employed by the Fulbe and Futanke states to control the Hayre, the internal dynamics of the region can only partly be explained by the influence of these central powers

Corporate motivation for integrated management system implementation : why do firms engage in integration of management systems: a literature review & research agenda\ud

Integration of management systems such as for quality, environment, occupational health and safety, risk management, and corporate social responsibilities is a viable organisational approach to cost reduction, efficient utilization of resources, greater motivation of employees, and better compliance to social obligations and stakeholders‘ requirements. Identification of drivers for corporate motivation for IMS decision making and its implementation is a matter of interest for academicians, practitioners, industry, and government regulatory agencies; paradoxically literature on this subject is pretty thin. This paper describes the literature review and research agenda for the exploration of drivers of IMS implementation and factors influencing IMS implementation. The exploratory research is meant to be executed by an inductive approach through case studies in Pakistani manufacturing firms

System implementation: managing project and post project stage - case study in an Indonesian company

The research reported in this paper aims to get a better\ud understanding of how the implementation process of\ud enterprise systems (ES) can be managed, by studying the\ud process from an organisational perspective. A review of\ud the literature on previous research in ES implementation\ud has been carried out and the state of the art of ES\ud implementation research is defined. Using several body of\ud literature, an organisational view on ES implementation is\ud described, explaining that ES implementation involves\ud challenges from triple domain, namely technological\ud challenge, business process related challenge, and\ud organisational challenge. Based on the defined state of the\ud art and the organisational view on ES implementation\ud developed in this research, a research framework is\ud presented, addressing the project as well as the postproject\ud stage, and a number of essential issues within the\ud stages. System alignment, knowledge acquisition, change\ud mobilisation are the essntial issues to be studied in the\ud project stage while institutionalisation effort and\ud continuous improvement facilitation are to be studied in\ud the post-project stage. Case studies in Indonesian\ud companies are used to explain the framework

Symmetry properties of Penrose type tilings

The Penrose tiling is directly related to the atomic structure of certain decagonal quasicrystals and, despite its aperiodicity, is highly symmetric. It is known that the numbers 1, $-\tau$, $(-\tau)^2$, $(-\tau)^3$, ..., where $\tau =(1+\sqrt{5})/2$, are scaling factors of the Penrose tiling. We show that the set of scaling factors is much larger, and for most of them the number of the corresponding inflation centers is infinite.Comment: Paper submitted to Phil. Mag.
