Land and agricultural commercialisation in Meru County,Kenya: evidence from three models*

What are the relative pros and cons of different pathways of agricultural commercialisation in Africa? This paper examines aspects of three commercial farming cases, each of which represents one of the three most dominant models of commercial agriculture – small-scale outgrowers, medium-size commercial farms and a large estate – in the high-potential area of Meru County in Kenya. The paper provides a comparative perspective across the cases, examining their outcomes in terms of land relations, labour, livelihoods and local economic linkages. The study used a mixed-methods approach, including a household survey and a range of qualitative methods including detailed life histories. We find diverse dynamics across our cases: increasing land consolidation spurred by the rising class of commercial coffee farmers, but also land fragmentation as a result of population pressure and prevalence of inheritance as a pathway to land acquisition in the case of horticultural outgrowers. The plantation generates relatively better paid employment for permanent skilled workers, while the commercial farms create employment for casualised, insecure and poorly paid seasonal labour. These labour regimes are highly gendered. The outgrowers combine family and hired labour. Across the three cases, farmers diversify income between on-farm and off-farm sources. The commercial and outgrower farms are dynamically integrated into the local economy, while the estate is less so. These features of the three models generate processes of social differentiation, which are reshaping the agrarian structure and rural economy in Meru County.     

Image analysis as an adjunct to sodium rhodizonate test in the evaluation of gunshot residues: an experimental study

It is important to investigate the clothing, as well as the body, to determine the range of fire of entry wounds in firearm injuries. Clothing can affect the amount of gunshot residues (GSR) reaching the body and their distribution. The amount and distribution of the GSR also vary according to the distance between the firearm and the target. Sodium rhodizonate test provides valuable data when clothing is available for examination. In the absence of clothing, light microscopic examinations may add additional information regarding the range of fire. In this study, a sodium rhodizonate test was done on 80 garment samples containing the bullet entrance. The 80 calfskin samples were processed histologically and were stained using Alizarin Red S. These were also evaluated with computer-assisted image analysis. Gross residues were seen on military camouflage clothing in samples from < or = 45-cm group. White flannel undershirts under the military camouflage contained rhodizonate-positive particles only around the contact wounds. With image analysis, however, the residues could be detected also in the skin samples of the 2.5-cm- and 5-cm-range groups. We suggest that the image analysis can be combined with other techniques and it can provide valuable data in the determination of entry wounds and also in the estimation of firing distance.     

Sudden death in infancy due to bicuspid aortic valve

Symptoms of bicuspid aortic valve usually occur in the age group of 50-70 years, but rarely, it can also lead to sudden unexpected death in infancy and early childhood. The autopsy of a 2-month-old baby boy, found dead in his cot, revealed the heart weight as 25 g, and the macroscopic examination showed the circumference of the aortic valve consisting of two leaflets as 8 mm. The thickness of the left ventricle, right ventricle, and septum was measured as 8, 7, and 10 mm, respectively. Microscopically, the heart revealed hypertrophic changes of myocytes. Subendocardial areas displayed necrosis of myocytes, and severe and diffuse ischemic changes characterized by loss of myofibers and vacuolization. Interstitial pneumonia was identified in the lungs. Death occurred as a result of a congenital bicuspid aortic valve obstructing the left ventricular outflow tract complicated by lung infection. As there are only a few reported cases in infancy, and congenital bicuspid aortic valve can lead to sudden unexpected death, this case is presented to the forensic community.     

Ethiopian federalism: autonomy versus control in the Somali region

This study examines the relationship between Ethiopia's federal and regional authorities since the Tigray led regime came to power in 1991. The redivision of Ethiopia into ethnic regions was aimed to effect two changes: to abolish certain ethnic domination of the state; and to enable various communities to govern their local affairs. Using material from the Somali Region, this article evaluates whether ethnic‐based regional authorities have sufficient autonomy from the centre to be accountable to local populations. The ability of local people to elect their leaders is central to undoing past ethnic injustices. Although communities have gained from the new order, however, the federal ruling party tightly controls regional political authorities. Federal domination of regional governance is partly the result of the ineptness of local elite. This arrangement creates formal ethnic regions without significantly altering power relations in Ethiopia. Consequently, the spirit of the 1991 change is lost as local communities lack leeway while a new ethnic group reigns supreme at the federal level.     

Subvalvular aortic stenosis as a cause of sudden death: two case reports

Sudden death is defined as a death that occurs suddenly, develops during an unpredictable course, and is due to natural or unnatural causes. Although there is no universally standardized definition on how "sudden" a sudden death is, WHO defines sudden death as a death that occurs within 24 hours after the onset of symptoms. The aim of this study is to present 2 rarely reported autopsy cases and to emphasize the importance of systemic autopsy at sudden death. On macroscopic examination, crescent-shaped, thick, fibrous membranes, located 5 mm and 3 mm away from the aortic valves, were detected. Fibrous membranes extended from the ventricular septum to the left ventricular outflow tract, thus apparently narrowing this region. Left ventricular wall and septum were slightly thickened, and there were scattered grayish-white areas of a small diameter. These became more intense in the septum and myocardium of the left ventricle on the anterior plane of the myocardial sections. In both cases, the aortic valves of were thickened and also markedly narrowed on one of them. In this case, the fibrous membrane adhered to the aortic valve and extended to the anterior leaflet of the mitral valve at one side. Both aortic valves comprised 3 leaflets. Other valves and coronary arteries showed no macroscopic pathologic findings. Microscopic examination of both cases demonstrated that the fibrous membrane comprising abundant collagen fibers was situated on the ventricular septum. Hypertrophy, moderate to severe interstitial fibrosis, and focal areas of scarring were observed in the specimens taken from the septal and ventricular myocardium. No abnormality was found on the conduction system examinations. Toxicologic analysis results in blood were negative. Based on the findings, membranous-type (discrete type) subvalvular aortic stenosis, diagnosed during the autopsy, was considered as the cause of sudden death in both cases.     

Estimation of stature from body parts

Anthropometric technique commonly used by anthropologists and adopted by medical scientists has been employed to estimate body size for over a hundred years. With the increasing frequency of mass disasters, the identification of an isolated lower extremity and the stature of the person it belonged to has created problems for the investigation of the identity of some of the victims. In spite of a need for such a study, there is a lack of systematic studies to identify fragmented and dismembered human remains. The purpose of the paper is to analyze anthropometric relationships between dimensions of the lower extremity and body height. Analysis is based on a sample of middle class male (N=203) and female (N=108) adult Turks residing in Istanbul. The participants are mostly students and staff members of a medical school, and military personnel. Measurements taken are stature, trochanteric height, thigh length, lower leg length, leg length, and foot height, breadth, and length. Of the five variables entered into the regression analysis, all but foot breadth participate in the analysis with leg length as the first and followed by thigh and foot lengths, and finally foot height in males (R(2)). There were also individually calculated formulae for some of these measurements which provided smaller R(2)-values. Student's t-test to assess if there was any intraobserver error in measurements take by individual anthropometrist did not show such any statistically significant difference. In conclusion, the study suggested that estimation of a living height can be made possible using various dimensions of the lower extremity. One must consider differences between populations in order to apply functions as such to others.
