Work-related well-being of Finnish anesthesiologists

Anesthesiologists, according to some studies, are highly stressed, die at a significantly earlier age than their colleagues and the general population,and are among the leaders in physicians' suicide records. Data are,however, sparse and contradictory. The aim of this study was to discover details of the work-related well-being of Finnish anesthesiologists. In 2004, a cross-sectional postal survey including all 550 working Finnish anesthesiologists produced a total of 328 responses (60%); 53% were men. The anesthesiologists had the greatest on-call workload among Finnish physicians. Their average in-hospital on-call period lasted 24 hours (range 14 to 38). Over two-thirds felt stressed. The most important causes of stress were work and combining work with family. Their main worries at work were: excessive workload and time constraints, especially being on call, organizational problems, and fear of harming patients. On-call workload correlated with burnout. Being frequently on call was correlated with severe stress symptoms--symptoms associated with sick leaves. Women were more affected by stress than men. High job control and organizational justice seemed to mitigate hospital-on-call stress symptoms. The respondents enjoyed fairly high job and life satisfaction. Job control and organizational justice were the most important correlates of these wellness indicators. Work-related factors were more important in males, whereas family life played a larger role in the well-being of female anesthesiologists. Women had less job control, fewer permanent job contracts, and a higher domestic workload. Of the respondents, 31% were willing to consider changing to another physician's specialty and 43% to a profession other than medicine. The most important correlates for these job turnover attitudes were conflicts at the workplace, low job control, organizational injustice, stress, and job dissatisfaction. One in four had at some time considered suicide. Respondents with poor health, low social support, and family problems were at the highest risk for suicidality. The highest risks at work were conflicts with co-workers and superiors, on-call-related stress symptoms, and low organizational justice. If a respondent had several risk factors, the risk for suicidality doubled with each additional factor. On-call work-burden, job control, fairness of decision-making procedures,and workplace relationships should be the focus in attempts to increase the work-related well-being of anesthesiologists.

Characterization of inhibition of platelet function by paracetamol and its interaction with diclofenac and parecoxib

Aim: To characterize the inhibition of platelet function by paracetamol in vivo and in vitro, and to evaluate the possible interaction of paracetamol and diclofenac or valdecoxib in vivo. To assess the analgesic effect of the drugs in an experimental pain model. Methods: Healthy volunteers received increasing doses of intravenous paracetamol (15, 22.5 and 30 mg/kg), or the combination of paracetamol 1 g and diclofenac 1.1 mg/kg or valdecoxib 40 mg (as the pro-drug parecoxib). Inhibition of platelet function was assessed with photometric aggregometry, the platelet function analyzer (PFA-100), and release of thromboxane B2. Analgesia was assessed with the cold pressor test. The inhibition coefficient of platelet aggregation by paracetamol was determined as well as the nature of interaction between paracetamol and diclofenac by an isobolographic analysis in vitro. Results: Paracetamol inhibited platelet aggregation and TxB2-release dose-dependently in volunteers and concentration-dependently in vitro. The inhibition coefficient was 15.2 mg/L (95% CI 11.8 - 18.6). Paracetamol augmented the platelet inhibition by diclofenac in vivo, and the isobole showed that this interaction is synergistic. Paracetamol showed no interaction with valdecoxib. PFA-100 appeared insensitive in detecting platelet dysfunction by paracetamol, and the cold-pressor test showed no analgesia. Conclusions: Paracetamol inhibits platelet function in vivo and shows synergism when combined with diclofenac. This effect may increase the risk of bleeding in surgical patients with an impaired haemostatic system. The combination of paracetamol and valdecoxib may be useful in patients with low risk for thromboembolism. The PFA-100 seems unsuitable for detection of platelet dysfunction and the cold-pressor test seems unsuitable for detection of analgesia by paracetamol.

Therapeutic hypothermia after cardiac arrest : Studies on neurological and cardiological outcome and prediction of outcome in hypothermia-treated patients resuscitated from out-of-hospital cardiac arrest

The outcome of the successfully resuscitated patient is mainly determined by the extent of hypoxic-ischemic cerebral injury, and hypothermia has multiple mechanisms of action in mitigating such injury. The present study was undertaken from 1997 to 2001 in Helsinki as a part of the European multicenter study Hypothermia after cardiac arrest (HACA) to test the neuroprotective effect of therapeutic hypothermia in patients resuscitated from out-of-hospital ventricular fibrillation (VF) cardiac arrest (CA). The aim of this substudy was to examine the neurological and cardiological outcome of these patients, and especially to study and develop methods for prediction of outcome in the hypothermia-treated patients. A total of 275 patients were randomized to the HACA trial in Europe. In Helsinki, 70 patients were enrolled in the study according to the inclusion criteria. Those randomized to hypothermia were actively cooled externally to a core temperature 33 ± 1ºC for 24 hours with a cooling device. Serum markers of ischemic neuronal injury, NSE and S-100B, were sampled at 24, 36, and 48 hours after CA. Somatosensory and brain stem auditory evoked potentials (SEPs and BAEPs) were recorded 24 to 28 hours after CA; 24-hour ambulatory electrocardiography recordings were performed three times during the first two weeks and arrhythmias and heart rate variability (HRV) were analyzed from the tapes. The clinical outcome was assessed 3 and 6 months after CA. Neuropsychological examinations were performed on the conscious survivors 3 months after the CA. Quantitative electroencephalography (Q-EEG) and auditory P300 event-related potentials were studied at the same time-point. Therapeutic hypothermia of 33ºC for 24 hours led to an increased chance of good neurological outcome and survival after out-of-hospital VF CA. In the HACA study, 55% of hypothermia-treated patients and 39% of normothermia-treated patients reached a good neurological outcome (p=0.009) at 6 months after CA. Use of therapeutic hypothermia was not associated with any increase in clinically significant arrhythmias. The levels of serum NSE, but not the levels of S-100B, were lower in hypothermia- than in normothermia-treated patients. A decrease in NSE values between 24 and 48 hours was associated with good outcome at 6 months after CA. Decreasing levels of serum NSE but not of S-100B over time may indicate selective attenuation of delayed neuronal death by therapeutic hypothermia, and the time-course of serum NSE between 24 and 48 hours after CA may help in clinical decision-making. In SEP recordings bilaterally absent N20 responses predicted permanent coma with a specificity of 100% in both treatment arms. Recording of BAEPs provided no additional benefit in outcome prediction. Preserved 24- to 48-hour HRV may be a predictor of favorable outcome in CA patients treated with hypothermia. At 3 months after CA, no differences appeared in any cognitive functions between the two groups: 67% of patients in the hypothermia and 44% patients in the normothermia group were cognitively intact or had only very mild impairment. No significant differences emerged in any of the Q-EEG parameters between the two groups. The amplitude of P300 potential was significantly higher in the hypothermia-treated group. These results give further support to the use of therapeutic hypothermia in patients with sudden out-of-hospital CA.

Atrial remodeling in atrial fibrillation : Epidemiological, clinical and magnetocardiographic aspects

Atrial fibrillation is the most common arrhythmia requiring treatment. This Thesis investigated atrial fibrillation (AF) with a specific emphasis on atrial remodeling which was analysed from epidemiological, clinical and magnetocardiographic (MCG) perspectives. In the first study we evaluated in real-life clinical practice a population-based cohort of AF patients referred for their first elective cardioversion (CV). 183 consecutive patients were included of whom in 153 (84%) sinus rhythm (SR) was restored. Only 39 (25%) of those maintained SR for one year. Shorter duration of AF and the use of sotalol were the only characteristics associated with better restoration and maintenance of SR. During the one-year follow-up 40% of the patients ended up in permanent AF. Female gender and older age were associated with the acceptance of permanent AF. The LIFE-trial was a prospective, randomised, double-blinded study that evaluated losartan and atenolol in patients with hypertension and left ventricular hypertrophy (LVH). Of the 8,851 patients with SR at baseline and without a history of AF 371 patients developed new-onset AF during the study. Patients with new-onset AF had an increased risk of cardiac events, stroke, and increased rate of hospitalisation for heart failure. Younger age, female gender, lower systolic blood pressure, lesser LVH in ECG and randomisation to losartan therapy were independently associated with lower frequency of new-onset AF. The impact of AF on morbidity and mortality was evaluated in a post-hoc analysis of the OPTIMAAL trial that compared losartan with captopril in patients with acute myocardial infarction (AMI) and evidence of LV dysfunction. Of the 5,477 randomised patients 655 had AF at baseline, and 345 patients developed new AF during the follow-up period, median 3.0 years. Older patients and patients with signs of more serious heart disease had and developed AF more often. Patients with AF at baseline had an increased risk of mortality (hazard ratio (HR) of 1.32) and stroke (HR 1.77). New-onset AF was associated with increased mortality (HR 1.82) and stroke (HR of 2.29). In the fourth study we assessed the reproducibility of our MCG method. This method was used in the fifth study where 26 patients with persistent AF had immediately after the CV longer P-wave duration and higher energy of the last portion of atrial signal (RMS40) in MCG, increased P-wave dispersion in SAECG and decreased pump function of the atria as well as enlarged atrial diameter in echocardiography compared to age- and disease-matched controls. After one month in SR, P-wave duration in MCG still remained longer and left atrial (LA) diameter greater compared to the controls, while the other measurements had returned to the same level as in the control group. In conclusion is not a rare condition in either general population or patients with hypertension or AMI, and it is associated with increased risk of morbidity and mortality. Therefore, atrial remodeling that increases the likelihood of AF and also seems to be relatively stable has to be identified and prevented. MCG was found to be an encouraging new method to study electrical atrial remodeling and reverse remodeling. RAAS-suppressing medications appear to be the most promising method to prevent atrial remodeling and AF.

Pitfalls in the Treatment of Persons with Dementia

Pitfalls in the treatment of persons with dementia Persons with dementia require high-quality health care, rehabilitation and sufficient social services to support their autonomy and to postpone permanent institutionalization. This study sought to investigate possible pitfalls in the care of patients with dementia: hip fracture rehabilitation, use of inappropriate or antipsychotic medication, social and medicolegal services offered to dementia caregiving families. Three different Finnish samples were used from years 1999-2005, mean age 78 to 86 years. After hip fracture operation, the weight-bearing restriction especially in group of patients with dementia, was associated with a longer rehabilitation period (73.5 days vs. 45.5 days, p=0.03) and the inability to learn to walk after six weeks (p<0.001). Almost half (44%) of the pre-surgery home-dwellers with dementia in our sample required permanent hospitalization after hip fracture. Potentially inappropriate medication was used among 36.2% of nursing home and hospital patients. The most common PIDs in Finland were temazepam over 15 mg/day, oxybutynin, and dipyridamole. However, PID use failed to predict mortality or the use of health services. Nearly half (48.4%) of the nursing home and hospital patients with dementia used antipsychotic medication. The two-year mortality did not differ among the users of conventional or atypical antipsychotics or the non-users (45.3% vs.32.1% vs.49.6%, p=0.195). The mean number of hospital admissions was highest among non-users (p=0.029). A high number of medications (HR 1.12, p<0.001) and the use of physical restraints (HR 1.72, p=0.034) predicted higher mortality at two years, while the use of atypical antipsychotics (HR 0.49, p=0.047) showed a protective effect, if any. The services most often offered to caregiving families of persons with Alzheimer s disease (AD) included financial support from the community (36%), technical devices (33%), physiotherapy (32%), and respite care in nursing homes (31%). Those services most often needed included physiotherapy for the spouse with dementia (56%), financial support (50%), house cleaning (41%), and home respite (40%). Only a third of the caregivers were satisfied with these services, and 69% felt unable to influence the range of services offered. The use of legal guardians was quite rare (only 4.3%), while the use of financial powers of attorney was 37.8%. Almost half (47.9%) of the couples expressed an unmet need for discussion with their doctor about medico-legal issues, while only 9.9% stated that their doctor had informed them of such matters. Although we already have many practical methods to develop the medical and social care of persons with AD, these patients and their families require better planning and tailoring of such services. In this way, society could offer these elderly persons better quality of life while economizing on its financial resources. This study was supported by Social Insurance Institution of Finland and part of it made in cooperation with the The Central Union of the Welfare for the Aged, Finland.

The Risk of Cancer Associated with Immunosuppressive Therapy for Skin Diseases

The possible carcinogenic risk of immunosuppressive therapies is an important issue in everyday clinical practise. Carcinogenesis is a slow multi step procedure, thus a long latency period is needed before cancer develops. PUVA therapy is used for many skin diseases including psoriasis, early stage cutaneous T cell lymphoma, atopic dermatitis, palmoplantar pustulosis and chronic eczema. There has been concern about the increased melanoma risk associated to PUVA therapy, which has previously been associated with an increased risk on non-melanoma skin cancer, especially squamous cell carcinoma. The increased risk of basal cell carcinoma (BCC) is also documented but it is modest compared to squamous cell carcinoma (SCC). This thesis evaluated melanoma and noncutaneous cancer risk associated to PUVA, and the persistence of nonmelanoma cancer risk after the cessation of PUVA treatment. Also, the influence of photochemotherapy to the development of secondary cancers in cutaneous T cell lymphoma and the role of short term cyclosporine in later cancer development in inflammatory skin diseases were evaluated. The first three studies were performed on psoriasis patients. The risk of melanoma started to increase 15 years after the first treatment with PUVA. The risk was highest among persons who had received over 250 treatments compared to those under 250 treatments. In noncutaneous cancer, the overall risk was not increased (RR=1.08,95% CI=0.93-1.24), but significant increases in risk were found in thyroid cancer, breast cancer and in central nervous system neoplasms. These cancers were not associated to PUVA. The increased risk of SCC was associated to high cumulative UVA exposure in the PUVA regimen. The patients with high risk had no substantial exposure to other carcinogens. In BCC there was a similar but more modest tendency. In the two other studies, the risk of all secondary cancers (SIR) in CTCL patients was 1.4 (95% CI=1.0-1.9). In separate sites, the risk of lung cancer, Hodgkin and non-Hodgkin lymphomas were increased. PUVA seemed not to contribute to any extent to the appearance of these cancers. The carcinogenity of short-term cyclosporine was evaluated in inflammatory skin diseases. No increased risk for any type of cancer including the skin cancers was detected. To conclude, our studies confirm the increased skin cancer risk related to PUVA treatment in psoriasis patients. In clinical practice, this has led to a close and permanent follow-up of patients treated with PUVA. In CTCL patients, PUVA treatment did not contribute to the development of secondary cancers. We could not detect any increase in the risk of cancer in patients treated with short term cyclosporine, unlike in organ transplant patients under such long-term therapy.

Molecular Genetics of Age-related Macular Degeneration

Age-related macular degeneration (AMD; OMIM # 603075) is an eye disease of the elderly, signs of which appear after the age of 50. In the Western world it is a leading cause of permanent visual loss with a prevalence of 8.5% in persons under 54 years of age and of 37% in persons over 75 years of age. Early forms of AMD may be asymptomatic, but in the late forms usually a central scotoma in the visual field follows severely complicating daily tasks. Smoking, age, and genetic predisposition are known risk factors for AMD. Until recently no true susceptibility genes had been identified though the composition of drusen deposits, the hallmarks of AMD, has suggested that the complement system might play a role in the pathogenesis of AMD. When four groups reported in March 2005, that, on chromosome 1q32, a Y402H variant in the complement factor H (CFH) gene confers risk for AMD in independent Caucasian samples, a new period in the field of genetic research of AMD started. CFH is a key regulator of the complement system. Thus, it is logical to speculate, that it plays a role in the pathogenesis of AMD. We performed a case-control association study to analyse whether the CFH Y402H variant contain a risk for AMD in the Finnish population. Although the population of Finland represents a genetic isolate, the CFH Y402H polymorphism was associated with AMD also in our patient sample with similar risk allele frequencies as in the other Caucasian populations. We further evaluated the effects of this variant, but no association between lesion subtype (predominantly classic, minimally classic or occult lesion) or lesion size of neovascular AMD and the CFH Y402H variant was detected. Neither did the variant have an effect on the photodynamic therapy (PDT) outcome. The patients that respond to PDT carried the risk genotype as frequently as those who did not respond, and no difference was found in the number of PDT sessions needed in patients with or without the risk genotypes of CFH Y402H. Functional analyses, however, showed that the binding of C-reactive protein (CRP) to CFH was significantly reduced in patients with the risk genotype of Y402H. In the past two years, the LOC387715/ high-temperature requirement factor A1 (HTRA1) locus on 10q26 has also been repeatedly associated with AMD in several populations. The recent discovery of the LOC387715 protein on the mitochondrial outer membrane suggests that the LOC387715 gene, not HTRA1, is the true predisposing gene in this region, although its biological function is still unknown. In our Finnish patient material, patients with AMD carried the A69S risk genotype of LOC387715 more frequently than the controls. Also, for the first time, an interaction between the CFH Y402H and the LOC387715 A69S variants was found. The most recently detected susceptibilty gene of AMD, the complement component 3 (C3) gene, encodes the central component of the complement system, C3. In our Finnish sample, an additive gene effect for the C3 locus was detected, though weaker than the effects for the two main loci, CFH and LOC387715. Instead, the hemicentin-1 or the elongation of very long chain fatty acids-like 4 genes that have also been suggested as candidate genes for AMD did not carry a risk for AMD in the Finnish population. This was the first series of molecular genetic study of AMD in Finland. We showed that two common risk variants, CFH Y402H and LOC387715 A69S, represent a high risk of AMD also in the isolated Finnish population, and furthermore, that they had a statistical interaction. It was demonstrated that the CFH Y402H risk genotype affects the binding of CFH to CRP thus suggesting that complement indeed plays an important role in the pathogenesis of AMD.

Pannus invasion into cartilage and bone in rheumatoid arthritis

Rheumatoid arthritis is the most common of all types of arthritis and despite of intensive research etiology of the disease remains unclear. Distinctive features of rheumatic arthritis comprise continuous inflammation of synovium, in which synovial membrane expands on cartilage leading to pannus tissue formation. Pannus formation, appearance of proteolytic enzymes and osteoclast formation cause articular cartilage and bone destruction, which lead to erosions and permanent joint damage. Proteolytic pathways play major roles in the development of tissue lesions in rheumatoid arthritis. Degradation of extracellular matrix proteins is essential to pannus formation and invasion. Matrix metalloproteinases (MMP) form a large proteolytic enzyme family and in rheumatoid arthritis they contribute to pannus invasion by degrading extracellular matrix and to joint destruction by directly degrading the cartilage. MMP-1 and MMP-3 are shown to be increased during cell invasion and also involved in cartilage destruction. Increase of many cytokines has been observed in rheumatoid arthritis, especially TNF-α and IL-1β are studied in synovial tissue and are involved in rheumatoid inflammation and degradation of cartilage. Underlying bone resorption requires first demineralization of bone matrix with acid secreted by osteoclasts, which exposes the collagen-rich matrix for degradation. Cathepsin K is the best known enzyme involved in bone matrix degradation, however deficiency of this protein in pycnodysostosis patient did not prevent bone erosion and on the contrary pannus tissue invading to bone did not expressed much cathepsin K. These indicate that other proteinases are involved in bone degradation, perhaps also via their capability to replace the role of other enzymes especially in diseases like pycnodysostosis or during medication e.g. using cathepsin K inhibitors. Multinuclear osteoclasts are formed also in pannus tissue, which enable the invasion into underlying bone matrix. Pannus tissue express a receptor activator of nuclear factor kappa B ligand (RANKL), an essential factor for osteoclast differentiation and a disintegrin and a metalloproteinase 8 (ADAM8), an osteoclast-activating factors, involved in formation of osteoclast-like giant cells by promoting fusion of mononuclear precursor cells. The understanding of pannus invasion and degradation of extracellular matrix in rheumatic arthritis will open us new more specific methods to prevent this destructive joint disease.

Studies of Earth Dynamics with the Superconducting Gravimeter

The superconducting (or cryogenic) gravimeter (SG) is based on the levitation of a super­conducting sphere in a stable magnetic field created by current in superconducting coils. Depending on frequency, it is capable of detecting gravity variations as small as 10-11ms-2. For a single event, the detection threshold is higher, conservatively about 10-9 ms-2. Due to its high sensitivity and low drift rate, the SG is eminently suitable for the study of geodynamical phenomena through their gravity signatures. I present investigations of Earth dynamics with the superconducting gravimeter GWR T020 at Metsähovi from 1994 to 2005. The history and key technical details of the installation are given. The data processing methods and the development of the local tidal model at Metsähovi are presented. The T020 is a part of the worldwide GGP (Global Geodynamics Project) network, which consist of 20 working station. The data of the T020 and of other participating SGs are available to the scientific community. The SG T020 have used as a long-period seismometer to study microseismicity and the Earth s free oscillation. The annual variation, spectral distribution, amplitude and the sources of microseism at Metsähovi were presented. Free oscillations excited by three large earthquakes were analyzed: the spectra, attenuation and rotational splitting of the modes. The lowest modes of all different oscillation types are studied, i.e. the radial mode 0S0, the "football mode" 0S2, and the toroidal mode 0T2. The very low level (0.01 nms-1) incessant excitation of the Earth s free oscillation was detected with the T020. The recovery of global and regional variations in gravity with the SG requires the modelling of local gravity effects. The most important of them is hydrology. The variation in the groundwater level at Metsähovi as measured in a borehole in the fractured bedrock correlates significantly (0.79) with gravity. The influence of local precipitation, soil moisture and snow cover are detectable in the gravity record. The gravity effect of the variation in atmospheric mass and that of the non-tidal loading by the Baltic Sea were investigated together, as sea level and air pressure are correlated. Using Green s functions it was calculated that a 1 metre uniform layer of water in the Baltic Sea increases the gravity at Metsähovi by 31 nms-2 and the vertical deformation is -11 mm. The regression coefficient for sea level is 27 nms-2m-1, which is 87% of the uniform model. These studies are associated with temporal height variations using the GPS data of Metsähovi permanent station. Results of long time series at Metsähovi demonstrated high quality of data and correctly carried out offsets and drift corrections. The superconducting gravimeter T020 has been proved to be an eminent and versatile tool in studies of the Earth dynamics.

Pelon ja toivon välissä : Pätkätyöläisen urakerronta

This study analyzes the forming of the occupational identity of the well-educated fixed-term employees. Fixed-term employment contracts amongst the well-educated labour force are exceptionally common in Finland as compared to other European countries. Two groups of modern fixed-term employees are distinguished. The first comprises well-educated women employed in the public sector whose fixed-term employment often consists of successive periods as temporary substitutes. The other group comprises well-educated, upper white-collar men aged over 40, whose fixed-term employment careers often consist of jobs of project nature or posts that are filled for a fixed period only. Method of the study For the empirical data I interviewed 35 persons (26 women and 9 men) in 33 interviews, one of which was conducted by e-mail and one was a group interview. All the interviews were electronically recorded and coded. All the interviewees have two things in common: fixed-term employment and formal high education. Thirteen (13) of them are researchers, four nurses, four midwives, four journalists, and ten project experts. I used the snowball method to get in touch the interviewees. The first interviewees were those who were recommended by the trade unions and by my personal acquaintances. These interviewees, in turn, recommended other potential interviewees. In addition, announcements on the internet pages of the trade unions were used to reach other interviewees. In analysing process I read the research material several times to find the turning points in the narrative the interviewees told. I also searched for the most meaningful stories told and the meaning the interviewees gave to these stories and to the whole narrative. In addition to that I paid attention to co-production of the narrative with the interviewees and analyzed the narrative as performance to be able to search for the preferred identities the interviewees perform. (Riesman 2001, 698-701). I do not pay much attention to the question of truth of a narrative in the sense of its correspondence with facts; rather I think a working life narrative has two tasks: On the one hand one has to tell the facts and on the other hand, he/she has to describe the meaning of these facts to herself/himself. To emphasize the double nature of the narrative about one’s working life I analyzed the empirical data both by categorizing it according to the cultural models of storytelling (heroic story, comedy, irony and tragedy) and by studying the themes most of the interviewees talked about. Ethics of the study I chose to use narrative within qualitative interviews on the grounds that in my opinion is more ethical and more empowering than the more traditional structured interview methods. During the research process I carefully followed the ethical rules of a qualitative research. The purpose of the interviews and the research was told to the interviewees by giving them a written description of the study. Oral permission to use the interview in this research was obtained from the interviewees. The names and places, which are mentioned in the study, are changed to conceal the actual identity of the interviewees. I shared the analysis with the interviewees by sending each of them the first analysis of their personal interview. This way I asked them to make sure that the identity was hidden well enough and hoped to give interviewees a chance to look at their narratives, to instigate new actions and sustain the present one (Smith 2001, 721). Also I hoped to enjoy a new possibility of joint authorship. Main results As a result of the study I introduce six models of telling a story. The four typical western cultural models that guide the telling are: heroic story, comedy, tragedy and satirical story (Hänninen 1999). In addition to these models I found two ways of telling a career filled with fixed-term employments that differ significantly from traditional career story telling. However, the story models in which the interviewees pour their experience locates the fixed term employers work career in an imagined life trajectory and reveals the meaning they give to it. I analyze the many sided heroic story that Liisa tells as an example of the strength of the fear of failing or losing the job the fixed term employee feels. By this structure it is also possible to show that success is felt to be entirely a matter of chance. Tragedy, the failure in one’s trial to get something, is a model I introduce with the help of Vilppu’s story. This narrative gets its meaning both from the sorrow of the failure in the past and the rise of something new the teller has found. Aino tells her story as a comedy. By introducing her narrative, I suggest that the purpose of the comedy, a stronger social consensus, gets deeper and darker shade by fixed-term employment: one who works as a fixed term employee has to take his/her place in his/her work community by him/herself without the support the community gives to those in permanent position. By studying the satiric model Rauno uses, I argue that using irony both turns the power structures to a carnival and builds free space to the teller of the story and to the listener. Irony also helps in building a consensus, mutual understanding, between the teller and the listener and it shows the distance the teller tells to exist between him and others. Irony, however, demands some kind of success in one’s occupational career but also at least a minor disappointment in the progress of it. Helmi tells her story merely as a detective story. By introducing Helmi’s narrative, I argue that this story model strengthens the trust in fairness of the society the teller and the listener share. The analysis also emphasizes the central position of identity work, which is caused by fixed-term employment. Most of the interviewees talked about getting along in working life. I introduced Sari’s narrative as an example of this. In both of these latter narratives one’s personal character and habits are lifted as permanent parts of the actual professional expertise, which in turn varies according to different situations. By introducing these models, I reveal that the fixed-term employees have different strategies to cope with their job situations and these strategies vary according to their personal motives and situations and the actual purpose of the interview. However, I argue that they feel the space between their hopes and fears narrow and unsecure. In the research report I also introduce pieces of the stories – themes – that the interviewees use to build these survival strategies. They use their personal curriculum vitae or portfolio, their position in work community and their work morals to build their professional identity. Professional identity is flexible and varies in time and place, but even then it offers a tool to fix one’s identity work into something. It offers a viewpoint to society and a tool to measure one’s position in surrounding social nets. As one result of the study I analyze the position the fixed-term employees share on the edge of their job communities. I summarize the hopes and fears the interviewees have concerning employers, trade unions, educational institutions and the whole society. In their opinion, the solidarity between people has been weakened by the short-sighted power of the economy. The impact the fixed-term employment has on one’s professional identity and social capital is a many-sided and versatile process. Fixed-term employment both strengthens and weakens the professional identity, social capital and the building of trust. Fixed-term employment also affects one’s day-to-day life by excluding her/him from the norm and by one’s difficulty in making long-term plans (Jokinen 2005). Regardless of the nature of the job contract, the workers themselves are experts in making the best of their sometimes less than satisfying work life and they also build their professional identity by using creatively their education, work experiences and interpersonal relations. However, a long career of short fixed-term employments may seriously change the perception of employee about his/her role. He/she may start concentrating only in coping in his/her unsatisfactory situation and leaves the active improvement of the lousy working conditions to other people.

Viestintää valtuustossa : Valtuutettujen viestintätyyli ja käsitys Helsingin kaupunginvaltuuston kokouksien viestinnästä

The goal of the study was to determine the kind of communication used in the meetings of the City Council. Councillors' addresses were studied by observing their communication styles. A questionnaire was used to study councillors' perception of communication in council meetings as perceived communication climate. A second goal of the study was to develop a method for analysing communication style. The nature of the study was a longitudinal case study. Studies of speech communication at the individual level and those of organisational communication at the community level served as the theoretical frame of reference. Due to the chosen object of study, political research and communication context shaped the frame of reference for the study. Verbal, nonverbal and paraverbal characteristics form the communication style. The perceived communication climate is dynamic in nature and consists of characteristics. The research material was gathered from the meetings of the Helsinki City Council held from 1993 to 1996. The communication style was analysed from meeting addresses (N=1271) given by the permanent members (N=95) of the council. The perceived communication climate was studied using a questionnaire modified from Wiio's OCD2 questionnaire. The questionnaire survey was carried out twice. The first time, 58 questionnaires (68%) were returned and, the second time, 49 questionnaires (58%) were returned. The method of analysis used for communication style was classification and cross tabulation. Based on the subset of material for the first year, five communication style categories were defined Communication style was examined using gender, length of council membership, and political party as subgroups. The results related to the perceived communication climate were analysed as averages and percentages. A comparison of the results from two different measuring times revealed how the perceived communication climate changed during a council term. The finding of the study was that the municipal politicians could be placed in all five communication style categories in each year of their four-year council term. The sizes of the style categories varied only little in the different years. A relatively stable - rather than changing - communication style was more characteristic of individuals during a council term. Gender did not explain an individual's communication style. On the other hand, the length of service in the council and, to some extent, the political party were connected with a certain communication style. Changes in style mainly manifested themselves as variation in communication activity so that activity was highest at the beginning and at the end of the council term. The method of researching communication style developed for this study proved to be functional, though labour-consuming. The perceived communication climate in the Helsinki City Council was good. Women's and men's satisfaction with the communication in the council differed; women's perception became considerably more positive at the end of the council term. Satisfaction with the communication in the council was characteristic of the Coalition Party and the Social Democrat councillors and dissatisfaction was characteristics of the Green councillors. Long council experience increased satisfaction with communication in the council. Only in the case of a few style categories was it possible to show any connection between the communication style and the perceived communication climate. The study confirmed the perception that an individual's communication style in the same communication context was relatively stable in the long term as well.

Hard Custom, Hard Dance : Social Organisation, (Un)Differentiation and Notions of Power in a Tabiteuean Community, Southern Kiribati

Hard Custom, Hard Dance: Social Organisation, (Un)Differentiation and Notions of Power in a Tabiteuean Community, Southern Kiribati is an ethnographic study of a village community. This work analyses social organisation on the island of Tabiteuea in the Micronesian state of Kiribati, examining the intertwining of hierarchical and egalitarian traits, meanwhile bringing a new perspective to scholarly discussions of social differentiation by introducing the concept of undifferentiation to describe non-hierarchical social forms and practices. Particular attention is paid to local ideas concerning symbolic power, abstractly understood as the potency for social reproduction, but also examined in one of its forms; authority understood as the right to speak. The workings of social differentiation and undifferentiation in the village are specifically studied in two contexts connected by local notions of power: the meetinghouse institution (te maneaba) and traditional dancing (te mwaie). This dissertation is based on 11 months of anthropological fieldwork in 1999‒2000 in Kiribati and Fiji, with an emphasis on participant observation and the collection of oral tradition (narratives and songs). The questions are approached through three distinct but interrelated topics: (i) A key narrative of the community ‒ the story of an ancestor without descendants ‒ is presented and discussed, along with other narratives. (ii) The Kiribati meetinghouse institution, te maneaba, is considered in terms of oral tradition as well as present-day practices and customs. (iii) Kiribati dancing (te mwaie) is examined through a discussion of competing dance groups, followed by an extended case study of four dance events. In the course of this work the community of close to four hundred inhabitants is depicted as constructed primarily of clans and households, but also of churches, work co-operatives and dance groups, but also as a significant and valued social unit in itself, and a part of the wider island district. In these partly cross-cutting and overlapping social matrices, people are alternatingly organised by the distinct values and logic of differentiation and undifferentiation. At different levels of social integration and in different modes of social and discursive practice, there are heightened moments of differentiation, followed by active undifferentiation. The central notions concerning power and authority to emerge are, firstly, that in order to be valued and utilised, power needs to be controlled. Secondly, power is not allowed to centralize in the hands of one person or group for any long period of time. Thirdly, out of the permanent reach of people, power/authority is always, on the one hand, left outside the factual community and, on the other, vested in community, the social whole. Several forms of differentiation and undifferentiation emerge, but these appear to be systematically related. Social differentiation building on typically Austronesian complementary differences (such as male:female, elder:younger, autochtonous:allotochtonous) is valued, even if eventually restricted, whereas differentiation based on non-complementary differences (such as monetary wealth or level of education) is generally resisted, and/or is subsumed by the complementary distinctions. The concomitant forms of undifferentiation are likewise hierarchically organised. On the level of the society as a whole, undifferentiation means circumscribing and ultimately withholding social hierarchy. Potential hierarchy is both based on a combination of valued complementary differences between social groups and individuals, but also limited by virtue of the undoing of these differences; for example, in the dissolution of seniority (elder-younger) and gender (male-female) into sameness. Like the suspension of hierarchy, undifferentiation as transformation requires the recognition of pre-existing difference and does not mean devaluing the difference. This form of undifferentiation is ultimately encompassed by the first one, as the processes of the differentiation, whether transformed or not, are always halted. Finally, undifferentiation can mean the prevention of non-complementary differences between social groups or individuals. This form of undifferentiation, like the differentiation it works on, takes place on a lower level of societal ideology, as both the differences and their prevention are always encompassed by the complementary differences and their undoing. It is concluded that Southern Kiribati society be seen as a combination of a severely limited and decentralised hierarchy (differentiation) and of a tightly conditional and contextual (intra-category) equality (undifferentiation), and that it is distinctly characterised by an enduring tension between these contradicting social forms and cultural notions. With reference to the local notion of hardness used to characterise custom on this particular island as well as dance in general, it is argued in this work that in this Tabiteuean community some forms of differentiation are valued though strictly delimited or even undone, whereas other forms of differentiation are a perceived as a threat to community, necessitating pre-emptive imposition of undifferentiation. Power, though sought after and displayed - particularly in dancing - must always remain controlled.

Matkailurakentaminen ja sen diskursiivinen rakentuminen Kilpisjärvellä

This master s thesis examines tourism related housing and related discourses in the village of Kilpisjärvi, Finland. I study the tourism development in Kilpisjärvi and the debate related to this process. My methodology is based on discourse and content analysis. The purpose of this study is to examine and classify the discourses of tourism related housing and what are the lessons learned from the recent development of Kilpisjärvi. Kilpisjärvi is the northernmost village in western Finnish Lapland, located in the middle of the highest mountain area of Finland. The area has been reindeer herding area of Saami people for centuries, but it has lacked permanent settlement until the beginning of 20th century. The first tourist accommodation was built in 1930s, followed by the road in 1940s and the hotel in 1950s. Traditionally the area has attracted skiers and hikers. The area is also known for its extraordinary nature and rare plant life. Tourism development was slow in Kilpisjärvi until the turn of millennium when rapid growth in tourism related housing was triggered by extensive land use planning. Small wilderness village of Kilpisjärvi has grown to a tourism centre with over 800 beds in commercial enterprises, more than hundred second-homes, and two large caravan areas. This development has raised conflicts among villagers. The empirical part of this study is based on the interviews of 17 permanent dwellers of Kilpisjärvi and three Norwegian cottage owners. Six discourses can be distinguished: 1) Nature and landscape, 2) Economy, 3) Place, 4)Reindeer herding, 5) Governance and 6) Possibilities to influence decision-making. The first discourse stressed that tourism development and building should adapt to nature and landscape, while economic discourse stressed the economical importance of tourism to Kilpisjärvi and the municipality of Enontekiö. The third discourse noted the change of Kilpisjärvi as a place due to the boom of tourism development. The discourse of reindeer herding was clearly distinguished from others, seeing tourism development merely negative. Governance was seen as an important tool in regulating development, but many saw that the municipal administration has failed to take into account other aspects of tourism development than economical factors. Many villagers saw their influence in decision-making weak, while landowners and municipal decision-makers were seen as oligarchy in land-use planning regardless of formal participatory planning process enforced by law. I conclude that it is important to take into account the diversity of local discourses in tourism development and land use issues. Transparent and genuine participatory planning process would promote sustainable development, prevent conflicts and allow decisions and development which would satisfy larger number of local dwellers than presently.

Breathing, swallowing and voice in laryngeal disorsers

The aim of this work was to examine how breathing, swallowing and voicing are affected in different laryngeal disorders. For this purpose, we examined four different patient groups: patients who had undergone total laryngectomy, anterior cervical decompression (ACD), or injection laryngoplasty with autologous fascia (ILAF), and patients with dyspnea during exercise. We studied the problems and benefits related to the automatic speech valve used for the rehabilitation of speech in laryngectomized patients. The device was given to 14 total laryngectomized patients who used the traditional valve especially well. The usefulness of voice and intelligibility of speech were assessed by speech pathologists. The results demonstrated better performance with the traditional valve in both dimensions. Most of the patients considered the automatic valve a helpful additional device but because of heavier breathing and the greater work needed for speech production, it was not suitable as a sole device in speech rehabilitation. Dysphonia and dysphagia are known complications of ACD. These symptoms are caused due to the stretching of tissue needed during the surgery, but the extent and the recovery from them was not well known before our study. We studied two patient groups, an early group with 50 patients who were examined immediately before and after the surgery and a late group with 64 patients who were examined 3 9 months postoperatively. Altogether, 60% reported dysphonia and 69% dysphagia immediately after the operation. Even though dysphagia and dysphonia often appeared after surgery, permanent problems seldom occurred. Six (12 %) cases of transient and two (3 %) permanent vocal cord paresis were detected. In our third study, the long-term results of ILAF in 43 patients with unilateral vocal cord paralysis were examined. The mean follow-up was 5.8 years (range 3 10). Perceptual evaluation demonstrated improved results for voice quality, and videostroboscopy revealed complete or partial glottal closure in 83% of the patients. Fascia showed to be a stable injection material with good vocal results. In our final study we developed a new diagnostic method for exertional laryngeal dyspnea by combining a cardiovascular exercise test with simultaneous fiberoptic observation of the larynx. With this method, it is possible to visualize paradoxal closure of the vocal cords during inspiration, which is a diagnostic criterion for vocal cord dysfunction (VCD). We examined 30 patients referred to our hospital because of suspicion of exercise-induced vocal cord dysfunction (EIVCD). Twenty seven out of thirty patients were able to perform the test. Dyspnea was induced in 15 patients, and of them five had EIVCD and four high suspicion of EIVCD. With our test it is possible to set an accurate diagnosis for exertional laryngeal dyspnea. Moreover, the often seen unnecessary use of asthma drugs among these patients can be avoided.

The struggle for protection of environmental refugees: who's responsibility? Discourses from the United Nations and Non-governmental organizations

This thesis identifies, examines and problematizes some of the discourses that have so far come to light on the issue of protection for environmental refugees. By analyzing the discourses produced by the United Nations Office of the High Commissioner for Refugees (UNHCR) and two non-governmental organizations - the Environmental Justice Foundation (EJF) and Equity and Justice Working Group Bangladesh (EquityBD), I examine the struggling discourses that have emerged about how protection for environmental refugees has been interpreted. To do this, I rely on Ernesto Laclau and Chantal Mouffe's theory and method of discourse analysis. The results show that responsibilization is the main point of struggle in the discussions on the protection of environmental refugees. As a floating signifier, it was utilized by the discourses produced by the UNCHR and the selected NGOs in contingent ways and with different political objectives. The UNHCR discourse responsibilized both the environmental refugees for their own protection and the individual states. The EJF and EquityBD, by contrast, allocated responsibility for the protection of environmental refugees to the international community. These contingent understandings of responsibilization necessitated different justifications. While the EJF discourse relied on humanitarianism for the assistance of environmental refugees, the EquityBD discourse constructed a rights based, more permanent solution. The humanitarian based discourse of the EJF was found to be inextricably linked with the neoliberal discourse produced by the UNHCR. Both these discourses encouraged environmental refugees to stay in their homelands, undermining the politics of protection. Another way in which protection was undermined was by UNHCR's discourse on securitization. In this context, climate change induced displacement became threat to developed countries, the global economy and transnational classes. The struggling discourses about who/what has been allocated responsibility for the protection of environmental refugees also meant that identities of the displaced be constructed in specific ways. While the UNHCR discourse constructed as voluntary migrants and predators, the EJF and EquityBD discourses portrayed them as victims. However, even though the EJF discourse constructed them as victims, their reliance on humanitarianism could also be interpreted as a way of giving the environmental refugee a predator like identity. These discourses on responsibilization and identity formation clashed with each other in the aim of achieving a hegemonic position in discussions and debates about the protection of environmental refugees.
