The influence of the type of accelerant, type of burned material, time of burning and availability of air on the possibility of detection of accelerants traces

The presented research consisted in a series of field experiments and laboratory analyses of obtained samples. Their aim was to investigate how different factors influence the possibility of identification of accelerant traces in conditions that are as similar as possible to those of real fires. The studied factors were: type of burned material, type of accelerant, length of time between lighting and extinguishing of fire and the air availability level. The obtained results show that, among investigated factors, the type of burned material has the greatest influence. The other factors, with regard to their influence, could be ranked in descending order as follows: 'other' (hard to determine and regulate factors), type of accelerant, time of burning and air availability. 'Other' factors include arrangement of the burned material and dispersion of the accelerant.

The influence of staffing levels on the use of seclusion

This study focussed on the relationship between the use of seclusion and staff characteristics, such as number of nurses on shift, male-female staff ratio, level of education and level of work experience. A retrospective analysis of staff characteristics was applied to administrative data from ten wards in four mid-sized general psychiatric hospitals in the Netherlands. The data show that two variables were associated with seclusion rates: the male-female staff ratio and the variability in team's work experience. More female and less male nurses in a shift and less variability in team's work experience predicted an increase in seclusion rates.     

The influence of sex hormones on the elimination kinetics of ethanol

The goal of the investigation was to research the influence of sex hormones on the elimination kinetics of ethanol. Forty-seven healthy men (average age 25+/-6.1 years) and 61 healthy women (average age 24+/-2.4 years) received 0.79-0.95g of ethanol/kg body weight in the form of an alcohol beverage of their choice. The target concentration for both sexes was a blood alcohol concentration (BAC) of 1.10g/kg. Blood samples for the determination of the ethanol concentration followed in the elimination phase in 10-20min intervals. The sex hormone levels (estradiol, progesterone and testosterone) were determined concomitantly from the serum. In men, the mean testosterone concentration was 5.3+/-1.6ng/ml, the mean estradiol concentration was 34.6+/-13.6pg/ml and the mean progesterone concentration was 0.9+/-0.3ng/ml. In women, the mean estradiol concentration was 47.6+/-52.6pg/ml and the mean testosterone concentration was 0.8+/-0.4ng/ml. Progesterone displayed a so-called dummy effect in women. In the high progesterone group (n=11), the mean concentration was 11.1+/-3.5ng/ml and in the low progesterone group (n=50) the mean was 0.6+/-0.3ng/ml. The mean hourly elimination rate (beta60) was 0.1677+/-0.0311g/kg/h in men. In women, the mean hourly elimination rate was 0.2044+/-0.0414g/kg/h in the high progesterone group and 0.1850+/-0.0276g/kg/h in the low progesterone group (p<0.05). The beta60 for women in the low progesterone group was significantly higher than that of the men, whose progesterone levels fell within a similar range (p>0.01). These results allow one to conclude that the gender differences in the pharmacokinetics of ethanol can partly, but not completely, be explained by progesterone levels.     

The governance of the financial action task force: an analysis of power and influence throughout the years

The international fight against money laundering illustrates changes in global governance as a result of the increasingly cross-border nature of crime and the need it creates for all involved to cooperate. The economic priorities and security concerns that surround it contributed to the strong evolution of global governance in this area and the status of anti-money laundering as a shared problem. The creation of the Financial Action Task Force (FATF), its expansion and cementation throughout the years, is a good example of the many forces working together to responding to the demands of emerging criminal threats and trends. It offers a good illustration of how relationships in global governance have influenced FATF’s priorities and action and ultimately the way in which illicit financial flows are tackled. This analysis offers an overview of FATF’s network across time taking into account the role of states, international organisations, and the private sector in the decision-making processes. It argues that Great Powers – a small, but aligned, group of states of global economic relevance – are responsible for FATF’s direction and the international efforts against illicit financial flows. It suggests, however, that unlike what could be expected, their power is declining following the rise of private sector influence through resourceful, organised and transnational actions e.g. on information sharing.     

The influence of the right to refuse treatment on precommitment patients

The unplanned extension of the right to refuse treatment to the precommitment period is described in this paper. This extension of the right to refuse treatment has important public policy implications for the civil commitment process. These implications, as well as the pros and cons of the extension of the right to refuse treatment, are discussed.

The influence of ethanol on the level of ketone bodies in hypothermia

Presently available possibilities of macro- and microscopic diagnosis of death from hypothermia are very limited as the changes observed are either weakly specific (ecchymoses in the mucous membrane of the stomach, histological features of haemorrhagic pancreatic necrosis, cardiomyocyte necrosis or decreased content of glycogen in hepatocytes) or represent only local action of low temperatures (frostbites, violet patches in the region of knees and elbows, red livores) and they may not be present in cases of death from cooling at environmental temperature close to zero or higher.The study evaluated the usefulness of acetoacetic acid (Ac-Ac), beta-hydroxybutyric acid (beta-HBA) and acetone determinations in blood, urine and vitreous humour for diagnosis of death from hypothermia. These three substances called ketone bodies, are easily assimilated energetic substrates that get oxidized preferentially before glucose and fatty acids. In hypoglycaemia (also hypothermia-induced one), the tissues dependent on glucose (e.g. the brain) cover most of their energetic needs from oxidation of these compounds.The analysis of 16 cases of death in circumstances suggesting hypothermia (mainly of the alcohol abusers) showed that the degree of ketosis was inversely proportional to the blood ethanol concentration. This relation may result from stimulation of insulin release and a decrease in the release of its antagonists by ethanol, as well as from inhibition of free fatty acid (FFA) beta-oxidation due to increase in the NADH/NAD ratio. So, the antiketonaemic effects of ethanol (together with its influence on the dilatation of the peripheral vessels and inhibition of shivering thermogenesis by muscle relaxation), explain increased sensitivity of intoxicated persons to low temperatures.     

The influence of forensic evidence on the case outcomes of homicide incidents

Objective

In spite of the growth of forensic science services little published research exists related to the impact of forensic evidence on criminal case outcomes. The present study focused on the influence of forensic evidence on the case processing of homicide incidents.

Materials and Methods

The study utilized a prospective analysis of official record data that followed homicide cases in five jurisdictions from the time of police incident report to final criminal disposition.

Results

The results showed that most homicides went unsolved (34.5% conviction rate). Only 55.5% of the 400 homicide incidents resulted in arrest of which 77% were referred to the district attorney. On the other hand, 94% of cases referred to the district attorney were charged. Cases were more likely to have arrests, referrals, and charges when witnesses provided information to the police. Suspects who knew their victims were more likely to be arrested and referred to the district attorney. Homicides committed with firearms were less likely to be cleared. The most noteworthy finding was that none of the forensic evidence variables significantly influenced criminal justice outcomes.

Conclusions

The study results suggest that forensic evidence is auxiliary and non-determinative for homicide cases.     

Scale, technique and composition effects in the Mexican agricultural sector: the influence of NAFTA and the institutional environment

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.

The influence of strain on law enforcement legitimacy evaluations

Purpose

While law enforcement officers have the state-sanctioned authority to use force as a way to ensure citizen obedience with the law, research has found that when private citizens evaluate the police as legitimate, they are more likely to comply with legal demands and cooperate with the police. Although procedural justice has shown to be a highly significant predictor of perceived police legitimacy, research has found other correlates of this outcome, including ethnic identity, low self-control and structural economic disadvantage. To date, no study has explored whether strain influences perceptions of the legitimacy of law enforcement.

Methods

A series of linear regression equations was estimated using survey data collected from a convenience sample of college students to determine the effect of strain on perceived police legitimacy.

Results

Even after controlling for procedural justice, strain exerted a negative and statistically significant influence on law enforcement legitimacy evaluations.

Conclusions

Police officers are encouraged to interact with citizens in procedurally just manners and to also consider people's strain levels when enforcing the law.     

The influence of camera-to-object distance and focal length on the representation of faces

When one thinks of the so-called barrel or wide-angle distortion, grotesquely warped faces may come to mind. For less extreme cases with primarily inconspicuous facial proportions, the question, however, still arises whether there may be a resulting impact on the identification of faces. In the first experiment, 3 test persons were photographed at a fixed camera-to-object distance of 2 m. In the second experiment, 18 test persons were each photographed at a distance of 0.5 m and 2.0 m. For both experiments photographs were taken from a fixed angle of view in alignment with the Frankfurt Plane. An isolated effect of the focal length on facial proportions could not be demonstrated. On the other hand, changes in the camera-to-object distance clearly influenced facial proportions and shape. A standardized camera-to-object distance for passport photos, as well as reconstruction of the camera-to-object distance from crime scene photos and the use of this same distance in taking photographs for comparison of suspects are called for. A proposal to refer to wide-angle distortion as the nearness effect is put forward.     

The influence of putrefactive changes on the determination of Paraquat in autopsy materials

This paper describes how the putrefactive changes in a cadaver will influence the determination of Paraquat in autopsy material. The carcasses of rats that had been given large doses of Paraquat and subsequently killed by cervical dislocation, were left at room temperature for up to seven days. Samples of stomach, caecum and liver were removed for the colorimetric determination of Paraquat with sodium dithionite following extraction on a Dowex 50W-4 column.Paraquat recovered from the stomach and caecum showed a decrease with time after death with the rate of decrease being greater in the caecum samples. However, the concentration of Paraquat in the liver increased for three days and then began to decrease gradually.The possible causes of these variations in Paraquat recovery are discussed. The findings appear to demonstrate the value of Paraquat determination even in samples from material that is in a state of advanced putrefaction.

The effect of board size and composition on European bank performance

Banks are “special” financial institutions generating distinct corporate governance challenges. The present paper examines the relationship between two of the most pertinent corporate governance factors—that is, the size of the Board of Directors and the proportion of non-executive directors—and firm performance on a sample of 58 large European banks over the period 2002–2004. The empirical analysis embraces a number of bank-specific variables. Our results reveal that bank profitability is negatively related to the size of the Board of Directors, while the impact of Board composition, although positive in all models, is, in most cases, insignificant. The results are robust after controlling for firm-specific variables.      

Measuring the autonomous influence of an international bureaucracy: the Division for Sustainable Development

International bureaucracies influence global governance processes as independent agents. Biermann and Siebenhüner (Managers of global change: the influence of international environmental bureaucracies. MIT Press, Cambridge, 2009) have developed an analytical framework to measure and explain the degree of autonomous influence of bureaucracies. We test the validity of the causal claims in the framework by applying it to the Division for Sustainable Development, the bureaucracy that services the Commission on Sustainable Development and compare the results with existing applications of the framework to the United Nations Environmental Program and the Climate Secretariat (UNFCCC). The test shows that the framework is comprehensive and captures the main elements of bureaucratic influence. The structure of the explanatory variables, however, as well as some causal claims, needs to be improved. For instance, the framework includes too many explanatory variables, and interplay between the variables is not taken into account. The article suggests five concrete measures to improve the framework by, for example, creating protocols, collapsing variables, and introduce weightings to the variables.
