Autonomous Controller-Aware Scheduling of Intra-Platoon V2V Communications.

In this paper, we investigate the problem of reducing the use of radio resources for vehicle-to-vehicle communications in an autonomous platooning scenario. Achieving reliable communications, which is a key element allowing for the tight coordination of platoon vehicles' motion, might be challenging in a case of heavy road traffic. Thus, in this paper, we propose to reduce the number of intra-platoon transmissions required to facilitate the safe autonomous control of vehicle mobility, by analyzing the impact of cars' behaviors (in terms of acceleration changes) on the evolution of the inter-vehicle distance errors within the platoon. We derive formulas representing the relation between the platoon leader's acceleration changes and the evolution of the distance error, velocity difference, and the accelerations for the first pair of vehicles. Furthermore, we propose a heuristic algorithm for selection of the intra-platoon messaging period for each platoon vehicle that minimizes the use of radio resources subject to the safety constraint, represented as the fraction of the total time when emergency braking is activated. The presented simulation results indicate that the proposed approach is capable of ensuring safe platoon operation and simultaneously providing a significant reduction in the use of resources, compared with conventional fixed-period transmission.

A Pill for the Ill? Patients' Reports of Their Experience of the Medical Encounter in the Treatment of Depression.

BACKGROUND: Starting in the 1960s, a broad-based patients' rights movement began to question doctors' paternalism and to demand disclosure of medical information, informed consent, and active participation by the individual in personal health care. According to scholars, these changes contributed to downplay the biomedical approach in favor of a more patient-oriented perspective. The Swedish non-profit organization Consumer Association for Medicines and Health (KILEN) has offered the possibility for consumers to report their perceptions and experiences from their use of medicines in order to strengthen consumer rights within the health care sector. METHODOLOGY: In this paper, qualitative content analysis was used to analyze 181 KILEN consumer reports of adverse events from antidepressant medications in order to explore patients' views of mental ill health symptoms and the doctor-patient interaction. PRINCIPAL FINDINGS: Overall, the KILEN stories contained negative experiences of the patients' medical encounters. Some reports indicated intense emotional outrage and strong feelings of abuse by the health care system. Many reports suggested that doctors and patients had very different accounts of the nature of the problems for which the patient was seeking help. Although patients sought help for problems like tiredness and sleeplessness (often with a personal crisis of some sort as a described cause), the treating doctor in most cases was exceptionally quick in both diagnosing depression and prescribing antidepressant treatment. When patients felt they were not being listened to, trust in the doctor was compromised. This was evident in the cases when the doctor tried to convince them to take part in medical treatment, sometimes by threatening to withdraw their sick-listing. CONCLUSIONS: Overall, this study suggests that the dynamics happening in the medical encounter may still be highly affected by a medical dominance, instead of a patient-oriented perspective. This may contribute to a questionable medicalization and/or pharmaceuticalization of depression.

Professionals' perceptions of and views about vocational rehabilitation for people with psychiatric disabilities.

OBJECTIVE: One of the challenges agencies and professionals face is to enable people on sick leave to be successful in their vocational rehabilitation. The objective of this study was to explore and analyze some professionals' perceptions of and views about vocational rehabilitation among people with psychiatric disabilities. PARTICIPANTS: Eight professionals from four different agencies (social services, the employment service, the social insurance office, and a psychiatric outpatient setting) working in the area of vocational rehabilitation for people with psychiatric disabilities. METHODS: Eight in-depth interviews were conducted. The data collected was analyzed using qualitative content analysis together with an interpretive approach. RESULTS: The results suggested the respondents were in consensus regarding that which they considered to facilitate or enable successful vocational rehabilitation. Intensive support over a long period of time and a holistic view that takes into account the habits and routines of daily life outside of work as well as the social and psychological aspects of individuals during their rehabilitation processes were considered to be just as crucial to the vocational rehabilitation process as training in the workplace. CONCLUSIONS: These professionals dealt with a complex vocational rehabilitation system; they felt that their organizations' directives and inability to collaborate successfully with other authorities restricted their scope of action and hindered their exercise of good practice.

Public health nursing and interprofessional collaboration in Norwegian municipalities: a questionnaire study.

The purpose of this study was to examine collaboration relating to public health nursing in different sized Norwegian municipalities. It sought to gain insight into factors that are important for successful collaboration, frequency of meeting points for collaborating activities and missing professionals in different sized municipalities. A cross-sectional e-post questionnaire study was carried out on a national sample of public health nurses and their collaborators. A total of 849 public health nurses (43.64%), 113 doctors at clinics and school health services (54.8%), 519 child protection workers (16.34%) and 115 midwives (41.3%) returned the questionnaire. The data were analysed using descriptive and inferential statistics. Analysis of variance (anova), Kruskal-Wallis H and chi-square tests were used to tests differences between groups. Trust, respect and collaborative competence were ranked highest by all the respondents and formalised structures, economy and leadership ranked least important in collaborative activity. The majority of the respondents stated that they do not have fewer meeting points compared with 5 years ago. Collaboration with mental health services was missed most by all respondents. There were associations between frequency of meeting points and statements on collaboration related to municipality size. Norway is in the throes of a major coordination reform. The fact that relational factors were deemed most important for successful collaboration is an important finding at a time when focus is on structural change. The findings indicate the need for further in depth qualitative studies on reasons for 'missing collaborators,' on professional cultures in different sized municipalities and on interpersonal relationships. Qualitative enquiry is necessary to gain a greater understanding of how relational concepts of respect, trust and conflict are understood by municipal public health professionals.

Internet-based mental health services in Norway and Sweden: characteristics and consequences.

Internet-based mental health services increase rapidly. However, national surveys are incomplete and the consequences for such services are poorly discussed. This study describes characteristics of 60 Internet-based mental health services in Norway and Sweden and discusses their social consequences. More than half of the services were offered by voluntary organisations and targeted towards young people. Professionals answered service users' questions in 60% of the services. Eight major themes were identified. These characteristics may indicate a shift in the delivery of mental health services in both countries, and imply changes in the understanding of mental health.

Experiences from consumer reports on psychiatric adverse drug reactions with antidepressant medication: a qualitative study of reports to a consumer association.

BACKGROUND: The new European pharmacovigilance legislation has been suggested as marking the beginning of a new chapter in drug safety, making patients an important part of pharmacovigilance. In Sweden since 2008 it has been possible for consumers to report adverse drug reactions (ADRs) to the Medical Products Agency (MPA), and these reports are now understood as an increasingly valuable contribution in the monitoring of safety aspects in medicines. Already in 2002 it was possible to report experiences with medicines to the non-profit and independent organization Consumer Association for Medicines and Health (KILEN) through a web-based report form with an opportunity to describe ADR experiences in free text comments. The aim of this study was to qualitatively analyze the free text comments appended to consumer reports on antidepressant medication. METHODS: All reports of suspected adverse reactions regarding antidepressant medications submitted from January 2002 to April 2009 to KILEN's Internet-based reporting system in Sweden were analyzed according to reported narrative experience(s). Content analysis was used to interpret the content of 181 reports with free text comments. RESULTS: Three main categories emerged from the analyzed data material: (1) Experiences of drug treatment with subcategories (a) Severe psychiatric adverse reactions, and (b) Discontinuation symptoms; (2) Lack of communication and (3) Trust and distrust. A majority of the reports to KILEN were from patients experiencing symptoms of mental disturbances (sometimes severe) affecting them in many different ways, especially during discontinuation. Several report included narratives of patients not receiving information of potential ADRs from their doctor, but also that there were no follow-ups of the treatment. Trust was highlighted as especially important and some patients reported losing confidence in their doctor when they were not believed about the suspected ADRs they experienced, making them attempt to discontinue their antidepressant treatment on their own. CONCLUSIONS: The present study indicates that free text comments as often contained in case reports directly submitted by patients can be of value in pharmacovigilance and provide important information on how a drug may affect the person using it and influence his or her personal life.

Reaching out to people struggling with their lives: a discourse analysis of answers from Internet-based services in Norway and Sweden.

The Internet has enlarged the scope of human communication, opening new avenues for connecting with people who are struggling with their lives. This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services' answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples' messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.

Struggles for recognition: a content analysis of messages posted on the Internet.

BACKGROUND: The Internet has enlarged the possibilities of human communication and opened new ways of exploring perceptions of mental health. This study is part of a research project aiming to explore, describe, and analyze different discourses of mental health in Norway and Sweden, using material from Internet-based services. AIM: To examine messages posed by users of publicly available question-and-answer services and to describe their content. METHODS: A Web search was used to identify Norwegian and Swedish Websites offering mental health services by email or posted messages. A total of 601 messages from 20 services, 10 Norwegian and 10 Swedish, were analyzed by means of qualitative content analysis and further interpreted in light of the social theory of recognition by Honneth. RESULTS: EIGHT CATEGORIES EMERGED FROM THE ANALYSIS: family life, couples, others, violence, the ungovernable, self-image, negotiating normality, and life struggles. These categories were then grouped into three themes: (1) relationship to significant others, (2) relationship to self, and (3) relationship to the social community. The themes promoted an understanding of mental health as closely connected to political and social factors. CONCLUSIONS: The results showed a variety of concerns from various parts of life and empowered the view that mental health should be understood broadly, at a conceptual level. Mental health emerged as a deeply relational concept that emphasized the equal distribution of chances in life. It strengthened the moral grammar of social inclusion and the acceptance of plurality in social life.

Implementation of standardized time limits in sickness insurance and return-to-work: experiences of four actors.

PURPOSE: In 2008, time limits were introduced in Swedish sickness insurance, comprising a pre-defined schedule for return-to-work. The purpose of this study was to explore experienced consequences of these time limits. Sick-listed persons, physicians, insurance officials and employers were interviewed regarding the process of sick-listing, rehabilitation and return-to-work in relation to the reform. METHOD: The study comprises qualitative interviews with 11 sick-listed persons, 4 insurance officials, 5 employers and 4 physicians (n = 24). RESULTS: Physicians, employers, and sick-listed persons described insurance officials as increasingly passive, and that responsibility for the process was placed on the sick-listed. Several ethical dilemmas were identified, where officials were forced to act against their ethical principles. Insurance officials' principle of care often clashed with the standardization of the process, that is based on principles of egalitarianism and equal treatment. CONCLUSIONS: The cases reported in this study suggest that a policy for activation and early return-to-work in some cases has had the opposite effect: central actors remain passive and the responsibility is placed on the sick-listed, who lacks the strength and knowledge to understand and navigate through the system. The standardized insurance system here promoted experiences of procedural injustice, for both officials and sick-listed persons.

What can we learn from consumer reports on psychiatric adverse drug reactions with antidepressant medication? Experiences from reports to a consumer association.

BACKGROUND: According to the World Health Organization (WHO) the cost of adverse drug reactions (ADRs) in the general population is high and under-reporting by health professionals is a well-recognized problem. Another way to increase ADR reporting is to let the consumers themselves report directly to the authorities. In Sweden it is mandatory for prescribers to report serious ADRs to the Medical Products Agency (MPA), but there are no such regulations for consumers. The non-profit and independent organization Consumer Association for Medicines and Health, KILEN has launched the possibility for consumers to report their perceptions and experiences from their use of medicines in order to strengthen consumer rights within the health care sector. This study aimed to analyze these consumer reports. METHODS: All reports submitted from January 2002 to April 2009 to an open web site in Sweden where anyone could report their experience with the use of pharmaceuticals were analyzed with focus on common psychiatric side effects related to antidepressant usage. More than one ADR for a specific drug could be reported. RESULTS: In total 665 reports were made during the period. 442 reports concerned antidepressant medications and the individual antidepressant reports represented 2392 ADRs and 878 (37%) of these were psychiatric ADRs. 75% of the individual reports concerned serotonin-reuptake inhibitor (SSRI) and the rest serotonin-norepinephrine reuptake inhibitor (SNRI). Women reported more antidepressant psychiatric ADRs (71%) compared to men (24%). More potentially serious psychiatric ADRs were frequently reported to KILEN and withdrawal symptoms during discontinuation were also reported as a common issue. CONCLUSIONS: The present study indicates that consumer reports may contribute with important information regarding more serious psychiatric ADRs following antidepressant treatment. Consumer reporting may be considered a complement to traditional ADR reporting.

From cooperation to conflict? Swedish rehabilitation professionals' experiences of interorganizational cooperation.

PURPOSE: This article analyses Swedish rehabilitation professionals' experiences of interorganizational cooperation in return-to-work and labour market reintegration. METHOD: Two groups (n = 15) from different organizations met on a regular basis to discuss their practice from a cooperation perspective. The participants had experience of cooperation in the organizational setting of Coordination Associations. The groups worked with a tutor according to a problem-based methodology, to discuss how their practice is influenced by new structures for cooperation. The material was analysed inductively using qualitative content analysis. RESULTS: Interorganizational cooperation in rehabilitation is generally perceived as promoting coherence and communication. Nevertheless, there are several contradictory factors in the implementation of such work forms, primarily inflexible sickness insurance regulations and inability of managers to implement cooperation in regular practice. CONCLUSIONS: While interorganizational cooperation promotes professional discretion and tailored solutions, the insurance system contradicts such ambitions through increased governance. Ultimately, the contradictory tendencies of cooperative initiatives and the stricter governance of sickness insurance regulations are political matters. If political attempts to promote interorganizational cooperation are to succeed, the increasing sectorization that results from strict governance of sickness insurance regulations needs to be targeted on a system level.

Swedish rehabilitation professionals' perspectives on work ability assessments in a changing sickness insurance system.

PURPOSE: Changes in the Swedish sickness insurance system shifts focus from return-to-work to labour market reintegration. This article analyses Swedish rehabilitation professionals' perspectives on how the changed regulations affect practice, with a special focus on work ability assessments. METHODS: Two groups of representatives (n = 15) from organizations involved in rehabilitation and return-to-work met at seven occations. The groups worked with a tutor with a problem-based approach to discuss how their practice is influenced by the changed regulations. The material was analysed inductively using qualitative content analysis. RESULTS: The new regulations require developed cooperation among insurance, health care, employers and occupational health care; however, these demands are not met in practice. In work ability assessments, several flaws regarding competence and cooperation are identified. An increasing number of people previously assessed as work disabled are required to participate in labour market reintegration, which puts demands on professionals to engage in motivational activities, although this is perceived as hopeless due to the group's lack of employability. CONCLUSIONS: The possibility for employers to sidestep their responsibility has increased with changed regulations. The overall lack of cooperation between relevant actors and the lack of relevant competence undermine the ambitions of activation and reintegration in the reform.

The bodily presence of significant others: Intensive care patients' experiences in a situation of critical illness.

This study is about intensive care patients and the bodily presence of significant others. The aim of the study is to inquire and understand the patients experience of the body in relation to their significant others during critical illness. Open, unstructured, in-depth interviews with six former intensive care patients provide the data for the study. The phenomenological-hermeneutical analysis points to a theme among ICU patients' experience of conflict between proximity and distance during the bodily presence of their relations. Patients experience different and conflicting forms of responses to the presence of their significant others. Patients experience significant positive confirmation but also negation through this presence. In the ICU situation, the reactions of significant others appear difficult to deal with, yet the physical presence is significant for establishing a sense of affinity. Patients seek to take some responsibility for themselves as well as for their relatives, and are met with a whole spectrum of reactions. Intensive care patients experience the need to be actively, physically present, which often creates sharp opposition between their personal needs and the needs of their significant others for active participation.

Sickness absence, social relations, and self-esteem: a qualitative study of the importance of relationships with family, workmates, and friends among persons initially long-term sickness absent due to back diagnoses.

OBJECTIVE: The aim of the present study was to explore and analyze accounts of social interactions and relationships with family, workmates, and friends supplied by persons with experience of sickness absence due to back, neck, or shoulder diagnoses. The focus was on experiences that seemed to involve positive and negative self-evaluative aspects, and therefore may be important to the self-conception and self-esteem of the absentee, and possibly to return to work. PARTICIPANTS: The interviewees were women and men between 25 to 34 years of age who had been sickness certified due to back, neck, or shoulder diagnosis. METHODS: A descriptive and explorative method was used to analyze data from five focus-group interviews. RESULTS: The importance of being supported and encouraged by family members, and the importance of feeling needed at work as well as being part of a social context were aspects stressed by the respondents. CONCLUSIONS: Our results indicate that these interactions and relations are important to the absentees' self-esteem, and that this should be taken into account when discussing rehabilitation efforts.

Focus on health, motivation, and pride: A discussion of three theoretical perspectives on the rehabilitation of sick-listed people.

OBJECTIVE/METHOD: During the last decades sickness absence from work has become a great societal problem. Questions of how rehabilitation processes should become successful and how peoples' ability to work can be improved have become of great public interest. In this paper we discuss three well-known theoretical perspectives regarding their usefulness when it comes to research on rehabilitation for return to work. RESULTS: The three perspectives are: Antonovsky's salutogenic model of health, Kielhofner's model of human occupation and Scheff's sociological theory of "shame and pride". CONCLUSIONS: Each of these can be applied to increase understanding and knowledge concerning sickness absence and return to work. We discuss points of affinity among the three perspectives, as well as significant differences, and we propose that a very essential common denominator is the importance of self-experience.

Towards a working life? Experiences in a rehabilitation process for people with psychiatric disabilities.

The aim of this study was to reveal the meaning some people with psychiatric disabilities assigned to important personal experiences in relation to an ongoing rehabilitation process. The data comprises open-ended interviews of eight participants. A hermeneutic approach together with a content analysis was used to analyse the data. The results indicated the importance of not relying on simplified prognoses early in a rehabilitation process when assessing rehabilitation measures and/or work capacity. The phenomenon of rehabilitation seemed to be very complex, diverse, and changed over time depending on different circumstances that arose during the rehabilitation process. These circumstances arose on individual, contextual as well as structural levels and all had an impact on the outcomes. The results also indicated that it seemed to be possible to achieve success, change attitudes, and create a positive image of a future related to a working life if the support was perceived as relevant and the activities undertaken were perceived as contributing to achievement of the individual's goals. Regardless of which path the informants later chose these factors were seen to support an empowerment process and active participation in their own rehabilitation.

A matter of trust? A study of coordination of Swedish stakeholders in return-to-work.

INTRODUCTION: Stakeholder cooperation in return-to-work has been increasingly emphasized over the last years. However, there is a lack of empirical studies on the subject. This study explores different public stakeholders' experiences of participating in Coordination Associations (CAs), a Swedish form of structured cooperation in return-to-work. The aim of the study is to determine the impact of stakeholder interests on the prerequisites for cooperation. METHODS: Thirty-five representatives from two CAs in eastern Sweden were interviewed regarding the aim, structure and strategies for their common work. RESULTS: Stakeholders' actions are to a high degree determined by their institutional preferences and self-interest. In the CAs, the motives for cooperation differ, and although these differences supposedly could be overcome, they are in fact not. One of the stakeholders, the Public Employment Service, limit its interest to coordinating resources, while the other three wishes to engage in elaborated cooperative work forms, implying the crossing of organizational borders. This discrepancy can largely be attributed to the difficulties for representatives from state authorities in changing their priorities in order to make cooperation work. CONCLUSIONS: Stakeholders' interests have a high impact on the prerequisites for cooperation in return-to-work. By referring to organizational goals, stakeholders engage in non-cooperative behaviour, which threatens to spoil cooperative initiatives and to develop distrust in cooperative work forms. The results of this study expose the complexity of and threats to cooperation, and its conclusions may be used by return-to-work stakeholders in different jurisdictions to improve the possibilities for the development of cooperative structures.

Perceptions of public health nursing practice by municipal health officials in Norway.

OBJECTIVES: The objective of this study was to describe and analyze municipal decision-maker's views on public health nursing and to reflect upon and discuss the relevance of those views to the future of public health nursing in Norway. DESIGN: This explorative qualitative study using face-to-face interviews is part of a larger project, comprising 5 studies, that explores perceptions of public health nursing. SAMPLE: A purposeful sample of 11 municipal decision-makers was selected for interview during 2006-2007 to reflect variation in community size and perspective. RESULTS: Thematic content analysis of the transcribed interviews revealed 4 content categories: contribution, collaboration, challenges, and visibility. The decision-makers expressed satisfaction with the public health nursing services, showed concern about lack of visibility and clear boundaries, and some expressed irritation over lacking collaboration. The interviewees elaborated on their past experiences as the public health nurses coworkers, leaders, collaborators, and service users. CONCLUSIONS: The respondents recognized public health nursing's contribution to public health but they lack sufficient knowledge of its content and tend to take services at local health clinics for granted. Dialogue between nurses and decision-makers is necessary in order to ensure updated evaluation and continued development of public health nursing services.

The work ability divide: holistic and reductionistic approaches in Swedish interdisciplinary rehabilitation teams.

INTRODUCTION: Stakeholder cooperation in return to work has been increasingly emphasised in research, while studies on how such cooperation works in practise are scarce. This article investigates the relationship between professionals in Swedish interdisciplinary rehabilitation teams, and the aim of the article is to determine the participants' definitions and uses of the concept of work ability. METHODS: The methods chosen were individual interviews with primary health care centre managers and focus groups with twelve interdisciplinary teams including social insurance officers, physicians, physiotherapists, occupational therapists, medical social workers and coordinators. RESULTS: The results show that the teams have had problems with reaching a common understanding of their task, due to an inherent tension between the stakeholders. This tension is primarily a result of two factors: divergent perspectives on work ability between the health professionals and the Social Insurance Agency, and different approaches to cooperative work among physicians. Health professionals share a holistic view on work ability, relating it to a variety of factors. Social insurance officers, on the other hand, represent a reductionistic stance, where work ability is reduced to medical status. Assessments of work ability therefore tend to become a negotiation between insurance officers and physicians. CONCLUSIONS: A suggestion from the study is that the teams, with proper education, could be used as an arena for planning and coordinating return-to-work, which would strengthen their potential in managing the prevention of work disability.

Metaphors of a shifting sense of self in men recovering from substance abuse and suicidal behavior.

The purpose of this descriptive study was to explore and interpret men's experience of sense of self within the context of recovery from substance abuse and suicidal behavior. A secondary analysis of data from a previous study of four young Norwegian men revealed how a shifting sense of self was constructed through the use of metaphors. The analysis identified three themes related to the participants' sense of self: The Meaning of Being Isolated, The Meaning of Being Close to the Point of No Return, and The Meaning of Still Being on the Edge. By acknowledging metaphorical expressions as a source of important knowledge, this study reflects on how mental health professionals can use metaphors in the recovery process. As part of the' treatment alliance and therapeutic communication, we suggest that metaphors may aid the assessment of suicidal ideation, promote a sense of a more active self, and signal acceptance and recognition of subjectivity.
