- The purpose of this study was to investigate the prevalence of toxic agents in attempted and completed suicides. The purpose was also to explore the sources of the drugs taken by suicide attempters. Verbal information on drug intake was collected from 280 suicide attempters during 1987-1990 in the Lund-Orup catchment area. Information on the sources of the drugs was collected from 143 of these attempters. The study also includes toxicological screening from 73 fatal poisonings in southern Sweden during 1989. According to verbal information, the most common drugs used by suicide attempters were benzodiazepines (51%), analgesics (29%) and antidepressants (20%). In suicide attempters, diazepam and levomepromazine were reported more than expected from prescription data. Toxicological screenings of fatal poisonings showed that benzodiazepines were most common (55%), followed by analgesics (38%), mainly propoxyphene (29%) and antidepressants (30%), mainly amitriptyline (22%). Amitriptyline and diazepam were more commonly detected in completed suicides than expected from prescription data. The most common sources of drugs to attempted suicides were physicians, and especially psychiatrists. We therefore conclude that continuous information to physicians on drug overdose is important, and it is also important to introduce alternative strategies to prevent suicidal behaviour.

Market-driven requirements engineering processes for software products - a report on current practices
- 2003
-
Konferensbidrag (refereegranskat)abstract
- This paper reports on some preliminary results from the first stage of an interview survey, focusing on current practices and challenges in market-driven RE. The interviews are analysed based on the characteristics of market-driven RE presented in the literature. The interviews correspond largely with the literature. Identified discrepancies compared with the literature concerns the time-to-market attribute and documentation of requirements. Two major groupings among the participating companies were found. The RE processes of one of these groupings are focused on facilitating the activities fundamental in market-driven RE, e.g. the release planning activity, while the other is more document-driven. The results of the interviews also include some ideas on how market-driven RE activities may be performed.

The Meta-Contrast Technique : a projective test predicting suicide
- 1992

Tidskriftsartikel (refereegranskat)abstract
- Sixty-nine inpatients who had attempted suicide were studied by means of the Meta-Contrast Technique (MCT), a projective test measuring personality factors, especially defensive strategies. The patients were divided into 3 subgroups, one of which was defined as stereotypy only, which denotes stereotypy (perceptual retardation) without any other coded defenses. At follow-up 7 of 8 completed suicides belonged to this subgroup and they matched various main diagnoses according to DSM-III-R. When the MCT findings of all patients were compared with 99 depressed inpatients from a previous study, the latter group more often had mature defensive strategies. In both investigations most completed suicides were found in the stereotypy only group. Our findings indicate that, regardless of psychiatric diagnosis, stereotypy without other defenses in MCT predicts suicide.

Challenges in Market-Driven Requirements Engineering - an Industrial Interview Study
- 2002
-
Ingår i: Proceeding of the Eighth International Workshop on Requirements Engineering: Foundation for Software Quality. ; , s. 37-49
-
Konferensbidrag (refereegranskat)abstract
- Requirements engineering for commercial off-the-shelf software packages entails special challenges. This paper presents preliminary results from an empirical study investigating these challenges through a qualitative approach using semi-structured interviews. The survey is exploratory with the objective of eliciting relevant topics for further research. Seven employees at five software companies with a market-driven development focus were interviewed. The areas of interest include process-related issues on release planning, requirements quality and decision support, as well as artefact-related issues regarding requirements as discrete entities and their representation. The paper also contains a characterization of each company, regarding aspects such as products, processes and customers. A number of challenging issues were elicited, including communication gaps between marketing and development, the problem of balancing the influence between marketing and development on requirements decisions, as well as the limited value of monolithic requirements specifications and the problem of requirements overloading.

- Requirements engineering for market-driven software development entails special challenges. This paper presents results from an empirical study that investigates these challenges, taking a qualitative approach using interviews with fourteen employees at eight software companies and a focus group meeting with practitioners. The objective of the study is to increase the understanding of the area of market-driven requirements engineering and provide suggestions for future research by describing encountered challenges. A number of challenging issues were found, including bridging communication gaps between marketing and development, selecting the right level of process support, basing the release plan on uncertain estimates, and managing the constant flow of requirement.s

The role of monoamines in suicidal behavior
- 1993

Tidskriftsartikel (refereegranskat)abstract
- Cerebrospinal fluid (CSF), urine, platelet and neuroendocrine challenge tests of monoaminergic function give evidence of monoamines, especially serotonin, playing an important role in suicidal behavior. However, additional clinical, social and biochemical factors are necessary to better define suicide-prone psychiatric patients.

Deliberate self‐poisoning : repeaters and nonrepeaters admitted to an intensive care unit
- 1991
-
Ingår i: Acta Psychiatrica Scandinavica. - : Wiley. - 0001-690X .- 1600-0447. ; 84:3, s. 266-271

Tidskriftsartikel (refereegranskat)abstract
- Seventy‐nine patients admitted to the Lund Intensive Care Unit after deliberate self‐poisoning were investigated by a psychiatrist and a social worker by means of a semi structured interview. Suicide risk evaluation included statistical risk factors according to the SAD PERSONS Scale, severity of suicidal intent according to the Suicidal Intent Scale, and interviewer reaction according to Motto. Two‐thirds of the patients were in treatment or had had counselling with a social worker. More than half of the sample were repeaters. Compared with nonrepeaters, repeaters were less often employed, lacked social support and more often had relational problems. The majority of the repeaters had ongoing treatment, mostly psychiatric treatment. Repeaters more often acted impulsively, and their suicidal intent tended to be less severe than those of nonrepeaters. Interviewers more often reacted with negative or neutral feelings towards repeaters. Our results indicate that those who repeat suicidal behaviour differ from nonrepeaters. Self‐poisoners, and especially repeaters, often had ongoing or previous psychiatric treatment. For the repeater group it is important to consider their impulse dyscontrol and their hostile attitude when alternative treatment strategies are devised and evaluated.
