Struggling against suicide: the need for an integrative approach

Transcultural comparisons would be beneficial for both our understanding of suicide phenomena and the setting up of preventative strategies. Changes in attitude throughout history, gender and age differences, socio-economic factors, influence of race and ethnicity, and the impact of religion are among the aspects mentioned in this article. All of them can actually have a considerable effect on suicide rates, and all of them should be taken into account when interpreting suicide trends and designing antisuicide strategies. In fact, both risk and protective factors may vary remarkably in different cultures. The need for an integrative approach is evident today more than ever, and this fact calls for more concerted and coordinated, multidisciplinary approaches to suicide prevention.     

3D measurements on extrusion marks in plastic bags

The surface of different types of garbage bags was scanned using non-contact laser profilometry. Manufacturing defects known from visual inspection of the bags (fish eyes, arrowheads, and surface scratches) appear as differences in the height profile. Extrusion lines could only be detected in low-density polyethylene bags. Their correlation length is a couple of centimeters, whereas visually they continue over meters. This can be used to link together the end of one garbage bag with the beginning of the subsequent bag. Extrusion lines are of the order of 0.1 microm for high-density polyethylene garbage bags.     

Multiple regression models for age estimation by assessment of morphologic dental changes according to teeth source

The aims of this study were twofold: (1). to measure parameters that contribute significantly to estimates of dental age, using a combination of classic methods and a computer-assisted image analysis procedure to avoid the bias inherent in observer subjectivity; and (2). to develop new mathematical regression models for age prediction according to postmortem interval. Two different populations were studied. Forty-three permanent teeth (Group I), extracted for valid clinical reasons, were taken from patients 25-79 years of age. The other population group (Group II) was composed of 37 healthy erupted permanent teeth obtained from human skeletal remains (age 22-82 years) with a postmortem interval ranging from 21 to 37 years. Morphologic age-related changes were investigated by measuring variables on intact and half-sectioned teeth. Multiple regression analyses were performed with age as the dependent variable for each sample source. In fresh extracted teeth, the variables that made the greatest contributions to predictions of age were dental attrition, dentin color, and translucency width, the latter measured with a computer-assisted image analysis method. In teeth from human skeletal remains, the variables that made the greatest contributions to age calculation were cementum apposition, pulp length measured by computer-assisted image analysis, dental attrition, root translucency, and dental color. We conclude by recommending different regression models to calculate age depending on the postmortem interval.     

Crisis intervention models in the French-speaking countries

The article presents the crisis intervention model devised by Andreoli (Geneva) which is currently being developed in most crisis units and emergency services in the French-speaking countries of Europe. Two clinical examples are presented: the Short Therapy Centre (Geneva, Switzerland) and the crisis unit of the Saint-Luc Clinic (Brussels, Belgium). The following aspects of these approaches are discussed: (a) the need for crisis intervention rather than a simple answer to emergency, (b) the need for crisis intervention in all acute psychiatric disorders and not only in psychosocial problems, (c) the need to integrate psychiatric hospitalization into a coherent mental health policy, (d) the need for well-trained and round-the-clock teams, (e) the need for continuity of care.     

The Implications of Childhood Sexual Abuse on Adult Social Behavior

Research indicates that childhood sexual abuse creates many long-term psychological difficulties, which may impair social behavior. These problems include anxiety, fear, depression, self-hatred, alienation, and suicidal tendencies. It was hypothesized that childhood sexual abuse would produce impaired social behavior in adults sexually abused as children. Two hundred and twenty-two male and female introductory psychology students from the University of Manitoba completed the Rand Corporation's Social Health Battery amplpar1978amprpar;, Linn's Social Dysfunction Rating Scale (1969), and a shortened version of Finkelhor's Sexual Victimization Survey (1979). Participants who experienced childhood sexual abuse exhibited impaired social behavior, which included fewer friends and social contacts, and more social adjustment problems. The importance of early intervention for children who experienced sexual abuse was discussed.     

An unusual case of suicide by means of a pneumatic hammer.

We describe an extraordinary case of a 49-year-old man who committed suicide by using a pneumatic hammer. As an industrial accident was initially assumed, difficulties in determining the manner of death are discussed. In addition, the ability to perform activity and evidence of a protracted agony in a situation of extensive cerebral destruction are considered. To our knowledge, no such case of suicide has ever been reported.     

Sweat testing in addicts under methadone treatment: an Italian experience

In determining the possibility that a specific weapon was responsible for a specific injury it is often valuable to examine the damage marks left on any clothing worn by a victim. Correlating this damage both to the skin and clothing with the dimensions of the suspect weapon (if available) may help in determining these possibilities. In this work four different types of knives were used to produce damage marks on various different fabrics both stretched and loose over skin. Statistically significant differences were found between the length of wound on the skin and the corresponding damage to the fabrics when the fabric was stretched over the skin while no statistically significant differences were observed when the fabric was loose over the skin. This was true for all of the knives examined.     

Reconstruction of ripped-up documents using fragment stack analysis procedures

Reconstruction of ripped-up documents can be a very time-consuming task for forensic experts. Currently, this task is often carried out using various homespun or loosely defined procedures. Under the main assumption that a (partially) ordered set of fragments can be recovered, we propose and discuss a more formal analysis methodology for this type of reconstruction problem. We discuss several complications that can occur in real-life problems and illustrate the efficiency of the proposed methods. Although several avenues for further research remain, we show that the proposed approach offers both a better understanding of the problem, as well as important strategies for devising very fast manual and semi-automatic fragment reassembly procedures.     

城市、社团和法律--从中世纪城市兴起看西方近代宪政制度

本文考察西方中世纪中晚期城市、社团及其城市法律制度。城市共同体的兴起促进了西欧范围的市场贸易活动的广泛复兴,并对中世纪欧洲封建地方体制给予了有力冲击;同时,城市共同体作为社团组织的独特发展形式,形成特有的城市等级会议制度,动摇和破坏封建社会的内部关系并为新社会结构的形成奠定了基础。这是导致历史上早期宪政观念产生的最为关键的因素。由于城市共同体自身的缺陷,统一市场的变革要求被民族国家所替代。
