Towards formulating effective research and development national strategies in Arab countries

Extremely weak R&D has a negative impact on growth and development in Arab countries. Developing a better R&D strategy could enhance capacity and effectiveness of R&D. The failure of the previously developed strategies in Arab countries was due to lack of vision, incorrect identification of R&D priorities, and disregard consulting stakeholders. This article discusses the challenges of developing R&D national strategies in Arab countries including identifying R&D priorities, managing stakeholders, assessing the current situation of R&D, and defining objectives of the strategies.     

Application of Volume‐of‐Fluid Method to Analyze the Viscosity Effect on the Spine Formation of Bloodstains

In bloodstain pattern analysis, the blood droplet volume and surface impact velocity play an important role, and many related experimental studies have been carried out. If an appropriate computational fluid dynamics (CFD) model that could solve bloodstain patterns, especially spine formation bloodstain patterns, can be obtained, the blood droplet volume and impact speeds at various crime scenes can be predicted more accurately. For this purpose, Flow‐3D software using the volume‐of‐fluid method was applied to analyze the behavior of human blood droplets during an impact event, especially focusing on the viscous effect on splashing, which forms the spine which can be used to predict the impact velocity. To obtain a non‐Newtonian viscosity model of blood for a computational fluid dynamic analysis, the venous blood samples of 163 people were tested using a hemorheology instrument. Among the venous blood samples of 163 people, 37 samples for which all blood test results were in a normal range were selected for the non‐Newtonian viscosity modeling. From the CFD analysis, it could be concluded that a non‐Newtonian viscosity model is more appropriate than a constant viscosity model for predicting splashing that forms the spine. The gradient of the non‐Newtonian model at a high shear rate has more of an effect on spine formation than that at a low shear rate. The lowest viscosity with a high velocity at the outer front of the radiating flow plays an important role in forming the splashing pattern.     

Acute Aortic Dissection Diagnosed after Embalming: Macroscopic and Microscopic Findings

A 58‐year‐old man died suddenly in Madagascar and poisoning was suspected. The body was embalmed after death and the general state of preservation was good. We found a major aortic dissection with a large false lumen from the aortic root to the common iliac arteries and a hemopericardium with formalinized blood clot. The intimal tear was on the ascending aorta, and an intramural hemorrhage was noted at the right coronary artery, attesting to a retrograde dissection. Microscopic studies confirmed aortic dissection with extensive intramural hemorrhage and also confirmed the retrograde dissection to the right coronary artery with a reduction of 90% of the true lumen. Classically, aortic dissection occurs in individuals with hypertension and individuals with genetic disorders of collagen formation. The diagnosis is often first established at the postmortem examination. Aortic dissection is therefore dealt with largely in necropsy studies. The usual cause of death is rupture into the pericardial sac. One case of bloodless dissection has been reported but the sudden death was explained by acute myocardial ischemia secondary to dissection of the left coronary artery. In our case, we found major hemopericardium and also intramural hemorrhage at the right coronary artery. We were able to make the diagnosis of aortic dissection and exclude the suspicion of homicide 15 days after death and after embalming.     

Long Bone (Humerus,Femur, Tibia) Measuring Procedure in Cadavers

In this work, we present a measuring methodology for long bones of the limbs (humerus, femur, and tibia) of human corpses. Measurements of cadaveric height and long bone lengths were conducted on 72 corpses (20 females and 52 males) from the School of Medicine at the National Autonomous University of Mexico. Additionally, these measurements were compared with those taken from dry bones of a subsample of individuals. Our results show marginal differences (TEM% = 0.59) between cadaveric and dry bone measurements, resulting from different osteometric technical procedures. This note outlines the measuring methodology, which will be subsequently used to create regression formulas for stature estimation.     

The Rationale Behind the Creation and Diffusion of Independent Regulatory Agencies: The Case of the Telecommunications Sector in Egypt

The creation and diffusion of Independent ^{1 1}Three different meanings of the regulatory state have been identified by Jordana and Levi-Faur (2004): the minimal, the prudent, and the overambitious meaning. The minimal meaning refers to the regulatory state as a field of study grouping scholars from different disciplines. The prudent meaning emphasises the tendency of modern states to use power and authority. An overambitious notion, the regulatory state developed to replace other state forms such as the welfare, developmental, and stabilisation state. Regulatory Agencies (IRAs) was greatly investigated in the context of the developed countries, particularly in Europe. Many scholars have provided different theories to explain the logic behind the formation and the spread of such agencies. These theories are important but not sufficient to explain the same phenomenon in the context of the developing countries wherein socio-economic and political environments are different. Adopting an institutional framework of analysis, and based on an in-depth qualitative documentary analysis and interviews with different stakeholders, this article investigates the creation and diffusion of the IRAs in Egypt particularly in the telecommunication sector. The findings show that the creation of the IRAs in the Egyptian telecommunications sector represents a rational response to the external isomorphic pressures exerted by international agency and can be explained on functional and practical grounds rather than any other factors of democratic governance or political uncertainties.     

Public management in South Asia: dimensions and directions of change

Public management in South Asia has been influenced by the colonial past which has resulted in the domination of administrative systems by the bureaucrats. Bureaucracies remained firmly entrenched as powerful groups and performed both administrative and political functions. India, Pakistan, Bangladesh, Nepal and Sri Lanka represent cases with similar backgrounds which opted for different political and economic systems after achieving independence. Consequently, a number of issues have emerged in public management in South Asia. These include debureaucratization of the policy process, complex relationship between specialists and generalists, integration of administrative structures, reconciliation of merit and equity, choice between professional and political patronage, revitalization of management, bridging the ever widening gap between the citizens and administrators, and the establishment of a sound ethical base of administration. The success of South Asian governments in dealing with these issues will determine, to a considerable extent, the dimensions and directions of change. While some of the issues will have to be addressed in the natural course of development, others will require a substantial degree of commitment from the governments as well as the societies.     

Shifting emphasis in the role of the state: Urban housing reform in China 1

Studies on the role of the state and its control over the economy favour a reduction of state involvement in the process. While such efforts were conducive to the political and economic arrangements in the capitalist world, China presented an entirely different challenge. The state played a dominant role in the production and delivery of all public goods and exercised effective control over the economy in China. However, the changing circumstances following China's adoption of liberalisation have set in motion a number of changes including an apparent reduction of state control over the economy. A case in point is the shift in the role of the state in the production and distribution of public housing in the urban areas. There have been efforts to introduce a market system in housing provision through privatisation, commercialisation and socialisation, and these have resulted in increased private home ownership as well as the formulation of new regulations to govern the real estate market. The intention was to gradually transfer the responsibility of production and management of this essential commodity to property development and professional management companies. However, the state has continued to play a prominent role on the pretext of protecting the citizens from negative consequences of the reforms. The state must take into consideration the nature of the society and its tradition of providing public services and adjust policies to derive maximum benefit from the reforms. As a result, the role of the state has shifted, rather than reduced, and the transformation provides a new perspective on the potential pitfalls in liberalising and rolling back the state.     

Measuring the efficiency of Spanish municipal refuse collection services

The aim of this article is to analyse the technical efficiency of the refuse collection services in 75 municipalities located in Catalonia, Spain. The analysis has been carried out using a great variety of techniques, both parametric and non‐parametric. Although the results naturally differ according to the technique used, they nevertheless are consistent in ranking the units analysed. Finally, we have looked into the relation existing between efficiency and the public or private management of the service. The results seem to support the idea that the framework for competition in which the service is provided could be more relevant than the private‐public management dichotomy.
