Advancing climate change policy in Jordan: strengthening national, regional and international positions. Policy brief

The Hashemite Kingdom of Jordan is one of the world’s most natural resource poor, arid and freshwater stressed countries. It is also exceptionally vulnerable to the effects of climate change and has limited mitigation and adaptation capacities. Importantly, the negative consequences of anthropogenic climate change have been exacerbated by associated infrastructural, demographic, and economic pressures. Hence, for the Hashemite Kingdom to ensure its national economic, social and political stability, it needs to develop and maintain robust mitigation and adaptation policies which accommodate a wide variety of voices. Furthermore, while Jordan (being a minor emitter) is rarely mentioned in global climate change talks, due to its importance in Middle Eastern regional politics, this situation needs to change and the country’s needs ought to be elevated at international discussions

Association between Multimorbidity and COVID-19 Mortality in Qatar: A Cross-Sectional Study

This study assessed the association between multimorbidity and mortality from COVID-19 in the Middle East and North Africa region, where such data are scarce. We conducted a cross-sectional study using data of all cases with COVID-19 reported to the Ministry of Public Health of Qatar from March to September 2020. Data on pre-existing comorbidities were collected using a questionnaire and multimorbidity was defined as having at least two comorbidities. Proportions of deaths were compared by comorbidity and multimorbidity status and multivariable logistic regression analyses were carried out. A total of 92,426 participants with a mean age of 37.0 years (SD 11.0) were included. Mortality due to COVID-19 was associated with gastrointestinal diseases (aOR 3.1, 95% CI 1.16–8.30), respiratory diseases (aOR 2.9, 95% CI 1.57–5.26), neurological diseases (aOR 2.6, 95% CI 1.19–5.54), diabetes (aOR 1.8, 95% CI 1.24–2.61), and CVD (aOR 1.5, 95% CI 1.03–2.22). COVID-19 mortality was strongly associated with increasing multimorbidity; one comorbidity (aOR 2.0, 95% CI 1.28–3.12), two comorbidities (aOR 2.8, 95% CI 1.79–4.38), three comorbidities (aOR 6.0, 95% 3.34–10.86) and four or more comorbidities (aOR 4.15, 95% 1.3–12.88). This study demonstrates a strong association between COVID-19 mortality and multimorbidity in Qatar

Effects of fungicides and bactericides on orchid seed germination and shoot tip cultures in vitro

Amphotericin B, benomyl, gentamycin, nystatin, quintozene penicillin G, sodium omadine, and vancomycin singly and in several combinations have no deleterious effects on the germination of orchid seeds, but inhibit the growth in vitro of shoot tip explants. © 1981 Martinus Nijhoff/Dr W.

An economy dominated by a public good : Egypt and the Nile over 5000 years

This thesis comprises the first systematic application of the theory of public goods to the study of the economics of Egypt during the 5000 years of its history. That history has provided an unparalleled experiment under quasi laboratory conditions. From the period of great coincidence that introduced agricultural technology in the Nile Valley, to the present day, that river with its system of irrigation has been an essentially indivisible instrument of production, a public good that has almost always dominated the economy. Over the ages, the country has been controlled by various rulers representing a number of very different civilizations: Pharaohs, Persians, Greeks, Romans, Arabs, Turks and British. Each new conquest influenced Egypt in its own way and introduced an element of foreign culture. Despite the diversity of these external influences, the qualities of timelessnes and changelessness have never ceased to mark the Egyptian scene. There has been a unique continuity in basic institutions and in the form and functions of government. In examining the economic history of Egypt, marked as it is by this same continuity, the present thesis proves to constitute a confirmation of the theory of public goods
