An innovative method for human height estimation combining video images and 3D laser scanning

Digitalization has increased the number of video surveillance systems that sometimes capture crime images. Traditional methods of human height estimation use projective geometry. However, sometimes they cannot be used because the video camera surveillance system is not available or has been moved and there are no reference lines on the frame. Scientific studies have developed a new method for human height estimation using 3D laser scanning. This model necessarily requires a series of approximations, which increase the final measurement error. To overcome this problem, in the present study, images of a subject are projected directly on the 3D model, estimating the height of the subject. This article describes the methodological approach adopted through the analysis of a real case study in a controlled environment executed by Carabinieri Forensic Investigation Department (Italy). The aim is to obtain a human anthropometric measure derived from frames extracted from the videos associated with the digital survey of the framed area obtained with 3D laser scanning and point cloud analysis. The result is the height estimation of five subjects filmed by a camera obtained through the combination of 2D images extracted by a DVR/surveillance systems with 3D laser scanning. Results show that most estimated measurements are less than the real measurement of the subject; it also depends on the posture of the subject while walking. Furthermore, results shows the differences between the real height and the estimated height with a statistical approach.     

Fatal poisoning due to ingestion of boiled oleander leaf extract

Nerium oleander is an ornamental evergreen shrub belonging to the family Apocynaceae. The Apocynaceae family includes the attractive evergreen shrub known as oleander. The cardiotoxic glycoside, oleandrin, is present in all portions of the common oleander plant. Oleander consumption can result in deadly situations accidentally or as a suicide attempt. After consuming kettle-boiled oleander leaf extract as part of a suicide attempt, an 80-year-old man was discovered comatose in his home and taken to our emergency room. The patient's heart rate was 30 beats per minute, and he had hypotension. Arterial blood gas analysis revealed remarkable metabolic acidosis and hyperkalemia (K: 7.7 mEq/L). An electrocardiogram showed a wide QRS wave, similar to a sine curve. The patient collapsed following cardiac arrest soon after hospital arrival. Veno-arterial extracorporeal membrane oxygenation was initiated; however, the patient eventually died. The serum level of oleandrin at hospital arrival, subsequently measured by LC–MS/MS, was found to be 33.4 ng/mL, far above the levels reported in previous fatal cases.     

Theory and Practice of Public Administration in the Philippines: Concerns for an Identity Crisis

Abstract

The discipline of public administration in the Philippines has been undergoing its version of an ‘identity crisis’ over the past decade. This crisis has been manifested in four areas: (1) the inordinate influence of mostly American public administration theories and concepts upon Philippines public administration has led Filipino academics in the early to mid-1980s to ask the question ‘is there a Philippine public administration?’; (2) the perceived disconnect between theories of public administration as taught in schools and the realities in the outside world has raised questions of the relevance of the discipline to real world challenges; (3) the continued frustration over the perception that in spite of many public administration and governance reforms, the Philippines continues to be among the more corrupt nations in the region; and (4) the recent fascination of academics in other disciplines, especially economists, that ‘institutions matter’, has led some public administration scholars to argue that their discipline has been arguing precisely the same point since the 1950s.     

Legislative Oversight under the Nigerian Presidential System

Oversight function is a major component of the activities of modern legislatures irrespective of the form of government in practice. This study examines the extent to which the Nigerian legislature, characterised by infrequent appearances on the political scene and operating in an environment largely dominated by the executive arm, has performed its oversight role. The study, which is basically empirical, argues that the Nigerian legislature has been incapable of effectively performing its oversight role because, in addition to constraints like executive interference, crippling internal conflict, inexperience and high rate of members turnover hampering legislative efficiency, the legislature has compromised its role. However, occasional flashes of a measure of assertiveness by the legislature suggest that with effective mitigation of its internal problems its performance will improve as legislative culture deepens.     

Después del consenso: el liberalismo en México (1990-2012)

This article explores the renewal of liberalism in Mexico over the last two decades. It argues that after the long period of one-party hegemonic rule, intellectuals have embraced many of liberalism’s tenets in public debates, such as economic and institutional reform, the defense of individual rights and freedom of expression, etc. It argues that the end of authoritarian rule made this renewal possible and attempts to account for key factors that unite intellectuals from very different ideological backgrounds.     

A Macro–Micro Analysis of the Effects of Electricity Reform in Senegal on Poverty and Distribution

This paper uses a computable general equilibrium (CGE) macro–micro model to explore the distributional effects of price reform in the electricity sector of Senegal. In the first part of the paper we analyse the distribution of electricity in Senegal by income quintiles, between 1995 and 2001. The analysis demonstrates that poor and rural households are not the main beneficiaries of the expanded network. The results of the CGE model show that direct price effects are weaker than general equilibrium effects on poverty and inequality. Moreover, compensatory policies tested can help attenuate some adverse effects.     

Colonisation,Institutions and Development: New Evidence

This article analyses current attempts to identify the factors underlying long-term economic growth. The author criticises some of the arguments and historical evidence on which the two main explanations that dominate recent literature are based: the institutional approach and the approach focusing on the importance of geographical factors. Using an approach which is deliberately eclectic, the author considers the role of geography, international trade, human capital and institutional quality in explaining development. A new estimation is carried out through Two Stages Least Squares (TSLS) with instrumental variables. The results of the empirical model confirm the central role of institutions in long-term economic growth. However, certain geographical conditions also seem to have influenced countries' chances of progress. The human capital is a less robust factor in explaining economic growth and trade openness does not seem significant in any estimation. Nevertheless, several questions remain to be answered, suggesting that cross-country estimations need to be complemented with a deeper historical analysis.     

Effect of Temperature on Bone Tissue: Histological Changes

The analysis of burned human remains has been of great interest among forensic anthropologists largely due to the difficulty that their recovery, classification, reconstruction, and identification present. The main purpose of this analysis is to present histological methodology for the interpretation of bones altered by thermal processes. We include analyses of the microscopic changes among bones exposed to different temperatures, with the goal of establishing categories of histological morphology in relation to fire temperature. Samples of bone (ilium) were exposed systematically to controlled temperatures. Analysis of the resulting histological changes has allowed the formation of a clear four‐stage classification of the alterations observed. This classification should prove useful in assessing bone changes in relation to temperature of exposure, particularly in cases where this temperature was previously not known.
