Metabolic syndrome in young adults – prevalence, childhood predictors and association with subclinical atherosclerosis

Background: Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors including central obesity, insulin resistance, impaired glucose tolerance, hypertension and dyslipidemia. The prevalence of MetS is increasing worldwide in all age groups. MetS is associated with increased risk of cardiovascular disease and type 2 diabetes mellitus. Aims: The aim of the present study was to investigate the prevalence, secular trends and childhood predictors of MetS in young adults. Furthermore, the relations between MetS and subclinical atherosclerosis were studied and whether apolipoproteins (apo) B and A-I, C-reactive protein (CRP) and type II secretory phospholipase A2 (sPLA2) were associated with MetS, and to what extent the atherogenicity of MetS was explained by these factors. Participants and Methods: The present thesis is part of the large scale population-based, prospective study, the Cardiovascular Risk in Young Finns Study. The first cross-sectional study was conducted in 1980 and included 3,596 participants aged 3-18 years. Carotid and brachial ultrasound studies were performed for 2,283 of these participants in 2001 and 2,200 of these participants in 2007. Results: The overall prevalence of MetS in young adults aged 24-39 years in 2001 was 10-15 % and 6 years later in 30-45 year-old adults it was 15-23 % depending on the MetS definition used. Between the years 1986 and 2001, MetS prevalence increased from 1.0 % to 7.5 % (p<0.0001) in 24-year-old participants that was mostly driven by the increased central obesity. Participants with MetS had increased carotid intima-media thickness (cIMT) and decreased carotid elasticity compared to those without the syndrome. Impaired brachial flow-mediated dilatation (FMD) was not related to MetS but it modified the relationship between MetS and cIMT (P for interaction 0.023). High levels of apoB, CRP, sPLA2 and low levels of apoA-I associated with MetS in young adults. In prospective analysis both MetS and high apoB predicted (P<0.0001) incident high cIMT, defined as cIMT>90th percentile and/or plaque. The association between MetS and incident high cIMT was attenuated by ~40 % after adjustment with apoB. Conclusions: MetS is common in young adults and increases with age. Screening for risk factors, especially obesity, at an early life stage could help identify children and adolescents at increased risk of developing MetS and cardiovascular disease later in life. MetS identifies a population of young adults with evidence of increased subclinical atherosclerosis. Impaired brachial endothelial response is not a hallmark of MetS in young adults, but the status of endothelial function modifies the association between metabolic risk factors and atherosclerosis. In addition, the atherogenicity of MetS in this population assessed by incident high cIMT appears to be substantially mediated by elevated apoB.

The Finnish Paper Workers' Union at a crossroads: Labor union representativeness in a changing environment, 1980-2008

This thesis consists of four articles and an introductory section. The main research questions in all the articles refer to the changes in the representativeness of the Finnish Paper Workers' Union. Representativeness stands for the entire entity of external, internal, legal and reputational factors that enable the labor union to represent its members and achieve its goals. This concept is based on an extensive reading of quantitative and qualitative industrial relations literature, which includes works based on Marxist labor-capital relations (such as Hyman's industrial relations studies), and more recent union density studies as well as gender- and ethnic diversity-based 'union revitalization' studies. Müller-Jentsch's German studies of industrial relations have been of particular importance as well as Streeck's industrial unionism and technology studies. The concept of representativeness is an attempt to combine the insights of these diverse strands of literature and bring the scientific discussion of labor unions back to the core of a union's function: representing its members. As such, it can be seen as a theoretical innovation. The concept helps to acknowledge both the heterogeneity of the membership and the totality of a labor union organization. The concept of representativeness aims to move beyond notions of 'power'. External representativeness can be expressed through the position of the labor union in the industrial relations system and the economy. Internal representativeness focuses on the aspects of labor unions that relate to the function of the union as an association with members, such as internal democracy. Legal representativeness lies in the formal legal position of the union – its rights and instruments. This includes collective bargaining legislation, co-decision rules and industrial conflict legislation. Reputational representativeness is related to how the union is seen by other actors and the general public, and can be approximated using data on strike activity. All these aspects of representativeness are path-dependent, and show the results of previous struggles over issues. The concept of representativeness goes beyond notions of labor union power and symbolizes an attempt to bring back the focus of industrial relations studies to the union's basic function of representing its members. The first article shows in detail the industrial conflict of the Finnish paper industry in 2005. The intended focus was the issue of gender in the negotiations over a new collective agreement, but the focal point of the industrial conflict was the issue of outsourcing and how this should be organized. Also, the issue of continuous shifts as an issue of working time was very important. The drawn-out conflict can be seen as a struggle over principles, and under pressure the labor union had to concede ground on the aforementioned issues. The article concludes that in this specific conflict, the union represented its' female members to a lesser extent, because the other issues took such priority. Furthermore, because of the substantive concessions. the union lost some of its internal representativeness, and the stubbornness of the union may have even harmed the reputation of the union. This article also includes an early version of the representativeness framework, through which this conflict is analyzed. The second article discusses wage developments, union density and collective bargaining within the context of representativeness. It is shown that the union has been able to secure substantial benefits for its members, regardless of declining employment. Collective agreements have often been based on centralized incomes policies, but the paper sector has not always joined these. Attention is furthermore paid to the changing competition of the General Assembly, with a surprisingly strong position of the Left Alliance still. In an attempt to replicate analysis of union density measures, an analysis of sectoral union density shows that similar factors as in aggregate data influence this measure, though – due to methodological issues – the results may not be robust. On this issue, it can be said that the method of analysis for aggregate union density is not suitable for sectoral union density analysis. The increasingly conflict-ridden industrial relations predicted have not actually materialized. The article concludes by asking whether the aim of ever-increasing wages is a sustainable one in the light of the pressures of globalization, though wage costs are a relatively small part of total costs. The third article discusses the history and use of outsourcing in the Finnish paper industry. It is shown using Hyman's framework of constituencies that over time, the perspective of the union changed from 'members of the Paper Workers' Union' to a more specific view of who is a core member of the union. Within the context of the industrial unionism that the union claims to practice, this is an important change. The article shows that the union more and more caters for a core group, while auxiliary personnel is less important to the union's identity and constituencies, which means that the union's internal representativeness has decreased. Maintenance workers are an exception; the union and employers have developed a rotating system that increases the efficient allocation of these employees. The core reason of the exceptional status of maintenance personnel is their high level of non-transferable skills. In the end it is debatable whether the compromise on outsourcing solves the challenges facing the industry. The fourth article shows diverging discourses within the union with regard to union-employer partnership for competitiveness improvements and instruments of local union representatives. In the collective agreement of 2008, the provision regulating wage effects of significant changes in the organization or content of work was thoroughly changed, though this mainly reflected decisions by the Labor Court on the pre-2008 version of the provision. This change laid bare the deep rift between the Social Democratic and Left Alliance (ex-Communist) factions of the union. The article argues that through the changed legal meaning of the provision, the union was able to transform concession bargaining into a basis for partnership. The internal discontent about this issue is nonetheless substantial and a threat to the unity of the union, both locally and at the union level. On the basis of the results of the articles, other factors influencing representativeness, such as technology and EU law and an overview of the main changes in the Finnish paper industry, it is concluded that, especially in recent years, the Finnish Paper Workers' Union has lost some of its representativeness. In particular, the loss of the efficiency of strikes is noted, the compromise on outsourcing which may have alienated a substantial part of the union's membership, and the change in the collective agreement of 2008 have caused this decline. In the latter case, the internal disunion on that issue shows the constraints of the union's internal democracy. Furthermore, the failure of the union to join the TEAM industrial union (by democratic means), the internal conflicts and a narrow focus on its own sector may also hurt the union in the future, as the paper industry in Finland is going through a structural change. None of these changes in representativeness would have been so drastic without the considerable pressure of globalization - in particular changing markets, changing technology and a loss of domestic investments to foreign investments, which in the end have benefited the corporations more than the Finnish employees of these corporations. Taken together, the union risks becoming socially irrelevant in time, though it will remain formally very strong on the basis of its institutional setting and financial situation.

Adherence and experimental infection of bacteria associated with periodontal infections of young cattle in Brazil ("Cara inchada")

In vitro- and in vivo-assays were conducted, to study the possible role of streptomycin- and actinomycin-producing soil actinomycetes for the pathogenesis of "Cara inchada" in cattle (CI). Adherence of Bacteroides spp. to epithelial cells of the bovine gingiva, known to be associated with the progressive lesions of CI, was significantly increased by the addition of streptomycin, actinomycin or antibiotic culture supernatants of the soil actinomycetes. Applications of these mixtures together with Actinomyces pyogenes to the marginal gingiva of the upper premolar teeth of about 1 month old Holstein Friesian calves did not lead to progressive lesions of CI. Only one calf exhibited a slight diarrhea and a temporary retraction of the gingiva at the site of application.

How (not) to interview children : interviews with young children in sexual abuse investigations in Finland

The present thesis had two main objectives: The first was to assess how child sexual abuse (CSA) interviews in Finland are conducted through analysing the interviewing techniques applied and the language used by the interviewers, as well as to suggest ways to improve interviews if they were found to have deficiencies. The second main aim was to contribute to the growing research corpus concerning CSA interviews, in particular, by addressing how interviewers follow up information provided by the child, by analysing whether child health care professionals would use childadapted language, and by studying the kind of modifications in the verbal behaviour of interviewers and children that were associated with a) repeated interviews, b) a support person’s presence at the interview, and c) the use of anatomically detailed dolls. Two complementary samples of CSA interviews were analysed. The first one was composed of child interviews with 3-12-year-old children (N = 27) that had been considered problematic by lawyers or other involved professionals (Studies I and IV). The second sample consisted of unselected interviews (N = 43) with children aged 3 to 8 years conducted in a number of hospitals in different parts of the country (Studies II and III). Study I: The verbal interaction between interviewer and child was analysed in a sample of interviews that had been considered to be problematic by involved professionals. Results showed that interviewers used inappropriate questioning techniques, relying on option-posing, specific suggestive and unspecific suggestive questions to a significant extent, these comprising around 50% of all interviewer utterances. The proportion of invitations, which the research community recommends interviewers to rely on, was strikingly low. Invitations and directive utterances were associated with an increase in informative responses by the child in terms of response type, number of new details reported, as well as length of response. The opposite was true for option-posing and suggestive utterances. Longer questions by the interviewer (in number of words) often rendered no reply from the child, whereas shorter questions were followed by descriptive answers. Even after the child had provided an informative answer, interviewers failed to follow up the information in an adequate way and instead continued to rely on focused and leading questions. Study II: Due to the possible bias of the sample analysed in Study I, the most important analyses were rerun with the unselected sample and reported separately. Results were quite similar between the two studies, indicating that the problems observed in Study I, with interviewers relying on option-posing and suggestive questions to a significant extent, are likely to be general and not specific for those interviews. Even if suggestive questions were slightly less and invitations slightly more common in this sample than in the previous study, almost half of the interviewer questions were still optionposing or suggestive, and also in this sample, interviewers failed to follow up information by the child in a facilitating manner. Differentiating between judicial and contextual details showed that while facilitators, invitations, and directive utterances elicited more contextual than judicial details, the opposite was true for specific suggestive utterances. These results might be explained by the reluctance of children to describe sexual details related to the abuse events. Alternatively, they may also be due to children describing incorrect sexual details as a result of suggestive interviewing techniques. Study III: This study examined features of the language used by the interviewers. Interviewer utterances included multiple questions, long statements, complicated grammar and concepts, as well as unclear references to persons and situations. More than a fifth of the interviewer utterances were coded as belonging to at least one of these categories. The results suggest that even professionals who are experienced in interacting with children may have difficulties in using a child-sensitive language, adding to the pool of studies showing similar problems to occur in legal hearings with children conducted by lawyers. As children rarely comment on, or even recognise, their lack of comprehension, the use of a language that is too complex can have detrimental consequences for the outcomes of investigative interviews. Interviewers used different approaches to introduce the topic of abuse. While 15% of the children spontaneously addressed the topic of abuse, probably indicating that they felt confident with the interviewer and the situation, in almost 50% of the cases, the interviewer introduced the topic of abuse in a way that can be considered leading. Interviews were characterised by a lack of structure, apparent in frequent rapid switches of topic by the interviewer. This manner was associated with a decrease in the number of new details provided by the children. Study IV: This study analysed possible changes in the interview dynamics associated with repeated interviewing, the presence of a support person (related to the child), and the use of anatomically detailed (AD) dolls. Repeated interviewing, in combination with suggestive questions, has previously been found to seriously contaminate children’s accounts. In the present material, interviewers used significantly more suggestive utterances in the repeated condition, thus endangering the reliability of the children’s reports. Few studies have investigated the effects of a support person’s presence at the interview. The results of the present study showed that interviewers talked more and children provided less information when a support person was present. Supporting some earlier findings regarding the use of AD dolls, the present results showed that using AD dolls was associated with longer interviewer utterances and shorter, less responsive, and less detailed child responses. Interviewers used up to five times more unspecific suggestive utterances when dolls were used, for instance through repeatedly asking the child to show “what really happened” with the dolls. Conclusion: The results indicate that CSA interviews in Finland are not conducted in a manner that follows best practice as defined by the research community and as stated in a number of guidelines. When comparing these questioning strategies with the recommendations, which have been predominant in the field for more than ten years now, it can be concluded that the interviews analysed were conducted in a manner that undermines the possibility to elicit an uncontaminated and accurate narrative from the children. A particularly worrying finding was the fact that interviewers did not follow up relevant information by the children in an adequate way. A number of clinical implications can be drawn from the results, particularly concerning the need for improvement in the quality of CSA interviews. There is convincing research regarding how to improve CSA interviews, notably through training forensic child interviewers to use a structured interviewing protocol, and providing them with continuous supervision and feedback. Allocating appropriate resources to improve the quality of forensic child interviews is a matter of protecting the rights of all persons involved in CSA investigations, in particular those of the children.

Oxidized LDL and physical fitness in healthy young men: associations with body composition, smoking, metabolic syndrome and androgen status

Background: In the past, oxidized low density lipoprotein (ox-LDL) has been associated with an unbeneficial lipid profile. This atherogenic lipid profile increases the risk of atherosclerotic cardiovascular diseases. Physical fitness has substantial effect on serum lipoprotein concentration as well as body composition and humoral responses, however interrelationships between ox-LDL and physical fitness have not been widely examined in a nationally representative sample. Aims: This thesis evaluates how cardiorespiratory and muscular fitness associate with ox-LDL lipids and how the other known risk factors of atherosclerosis might alter these associations. Subjects and Methods: The study cohort consisted of 846 healthy young males (mean age 25.1, SD 4.6) who were gathered by voluntary nationwide recruitment. Each participant conducted a series of physical fitness tests (cardiorespiratory and muscular fitness) and answered a detailed questionnaire that included lifestyle habits (i.e. smoking and leisuretime physical activity). Venous blood samples including ox-LDL and serum lipids were also collected. Results: Higher levels of ox-LDL were found in overweight and obese men, however, high cardiorespiratory fitness seemed to protect the overweight from high levels of ox-LDL. Young men who smoked and had poor cardiorespiratory or muscular fitness possessed a higher concentration of ox-LDL lipids when compared to comparable levels of cardiorespiratory or muscular fitness non-smoking young men. Metabolic syndrome was associated with increased levels of ox-LDL and high levels of ox-LDL combined with poor cardiorespiratory and abdominal muscle fitness seems to predict metabolic syndrome in young men. Also, participants with poor cardiorespiratory fitness and low levels of testosterone had higher levels of ox-LDL when compared to participants with high cardiorespiratory fitness / low testosterone as well as those with poor cardiorespiratory fitness / high testosterone. Conclusions: Good cardiorespiratory and muscular fitness protects young men from increased levels of ox-LDL lipids. This association was discovered in young men who were categorized as being overweight, smokers, metabolic syndrome or with low levels of testosterone. Being fit seems to prevent higher levels of ox-LDL, even in young healthy

Weed control in young coffee plantations through post emergence herbicide application onto total area

This study was carried out to investigate the efficiency of several herbicides under field conditions, by post-emergence application onto the entire area, their effect on the control of weeds in young coffee plantations and commercial coffee and bean intercropping system, as well as on both crops. Seedlings of Coffea arabica cv. Red Catuaí with four to six leaf pairs were transplanted to the field and treated according to conventional agronomic practices. A bean and coffee intercropping system was established by sowing three lines of beans in the coffee inter-rows. At the time the herbicides were sprayed, the coffee plants had six to ten leaf pairs; the bean plants, three leaflets; and the weeds were at an early development stage. Fluazifop-p-butyl and clethodim were selective for coffee plants and controlled only Brachiaria plantaginea and Digitaria horizontalis efficiently. Broad-leaved weeds (Amaranthus retroflexus, Bidens pilosa, Coronopus didymus, Emilia sonchifolia, Galinsoga parviflora, Ipomoea grandifolia, Lepidium virginicum, and Raphanus raphanistrum) were controlled with high efficiency by sole applications of fomesafen, flazasulfuron, and oxyfluorfen, except B. pilosa, C. didymus, and R. raphanistrum for oxyfluorfen. Sequential applications in seven-day intervals of fomesafen + fluazifop-p-butyl, or clethodim, and two commercial mixtures of fomesafen + fluazifop-p-butyl simultaneously controlled both types of weed. Cyperus rotundus was only controlled by flazasulfuron. Except for fluazifop-p-butyl and clethodim, all herbicide treatments caused only slight injuries on younger coffee leaves. However, further plant growth was not impaired and coffee plant height and stem diameter were therefore similar in the treatments, as evaluated four months later. Fomesafen, fluazifop-p-butyl, and clethodim, at sole or sequential application, and the commercial mixtures of fomesafen + fluazifop-p-butyl were also highly selective for bean crop; thus at doses recommended for bean crop, these herbicides may be applied to control weeds in coffee and bean intercropping systems by spraying the entire area.

Effects of weed species competition on the growth of young coffee plants

The effects of competition of seven weed species on the growth of coffee plants were evaluated under greenhouse conditions. Thirty days after coffee seedling transplantation into 12 L pots with soil level area of 6.5 dm², weeds were transplanted into or sown in those pots, at densities of 0, 1, 2, 3, 4 and 5 plants per pot. Competition or weedy periods from weed transplantation or emergence to plant harvesting, at weed pre-flowering stage, were: 77 days - Bidens pilosa, 98 days - Brachiaria decumbens, 180 days - Commelina diffusa, 82 days - Leonurus sibiricus, 68 days - Nicandra physaloides, 148 days - Richardia brasiliensis and 133 days - Sida rhombifolia. Coffee plant height, stem diameter, leaf number and shoot dry matter were determined. Effects of competition by N. physaloides and S. rhombifolia against coffee plants were among the lowest, since only a slight decrease in all the characteristics evaluated in coffee plants was observed. The other weed species caused severe decrease in growth, mainly with increasing weed plant densities. Competition degree was found to depend on weed species and density.

Young Registered Nurses’ Intent to Leave the Profession in Finland - A Mixed-Method Study

The purpose of this study was to examine and expand understanding concerning young Finnish registered nurses (RN) with an intention to leave the profession and the related variables, specifically when that intention has emerged before the age of 30. The overall goal of the study was to develop a conceptual model in relation to young RNs’ intention to leave the profession. Suggestions for policymakers, nurse leaders and nurse managers are presented for how to retain more young RNs in the nursing workforce. Suggestions for future nursing research are also provided. Phase I consists of two sequential integrative literature reviews of 75 empirical articles concerning nurses’ intention to leave the profession. In phase II, data had been collected as part of the Nurses’ Early Exit (NEXT) study, using the BQ-12 structured postal questionnaire. A total of 147 young RNs participated in the study. The data were analysed with statistical methods. In phase III, firstly, an in-depth interpretive case study was conducted in order to understand how young RNs explain and make sense of their intention to leave the profession. The data in this study consisted of longitudinal career stories by three young RNs. The data was analysed by using narrative holistic-content and thematic methods. Secondly, a total of 15 young RNs were interviewed in order to explore in-depth their experiences concerning organizational turnover and their intent to leave the profession. The data was analysed using conventional content analysis. Based on earlier research, empirical research on the young RNs intention to leave the profession is scarce. Nurses’ intention to leave the profession has mainly been studied with quantitative descriptive studies, conducted with survey questionnaires. Furthermore, the quality of previous studies varies considerably. Moreover, nurses’ intention to leave the profession seems to be driven by a number of variables. According to the survey study, 26% of young RNs had often considered giving up nursing completely and starting a different kind of job during the course of the previous year. Many different variables were associated with an intention to leave the profession (e.g. personal burnout, job dissatisfaction). According to the in-depth inquiries, poor nursing practice environments and a nursing career as a ‘second-best’ or serendipitous career choice were themes associated with young RNs’ intention to leave the profession. In summary, young RNs intention to leave the profession is a complex phenomenon with multiple associated variables. These findings suggest that policymakers, nurse leaders and nurse managers should enable improvements in nursing practice environments in order to retain more young RNs. These improvements can include, for example, adequate staffing levels, balanced nursing workloads, measures to reduce work-related stress as well as possibilities for advancement and development. Young RNs’ requirements to provide high-quality and ethical nursing care must be recognized in society and health-care organizations. Moreover, sufficient mentoring and orientation programmes should be provided for all graduate RNs. Future research is needed into whether the motive for choosing a nursing career affects the length of the tenure in the profession. Both quantitative and in-depth research is needed for the comprehensive development of nursing-turnover research.

Assessment of Young Learners’ English Proficiency in Bilingual Content Instruction CLIL

This applied linguistic study in the field of second language acquisition investigated the assessment practices of class teachers as well as the challenges and visions of language assessment in bilingual content instruction (CLIL) at primary level in Finnish basic education. Furthermore, pupils’ and their parents’ perceptions of language assessment and LangPerform computer simulations as an alternative, modern assessment method in CLIL contexts were examined. The study was conducted for descriptive and developmental purposes in three phases: 1) a CLIL assessment survey; 2) simulation 1; and 3) simulation 2. All phases had a varying number of participants. The population of this mixed methods study were CLIL class teachers, their pupils and the pupils’ parents. The sampling was multi-staged and based on probability and random sampling. The data were triangulated. Altogether 42 CLIL class teachers nationwide, 109 pupils from the 3rd, 4th and 5th grade as well as 99 parents from two research schools in South-Western Finland participated in the CLIL assessment survey followed by an audio-recorded theme interview of volunteers (10 teachers, 20 pupils and 7 parents). The simulation experimentations 1 and 2 produced 146 pupil and 39 parental questionnaires as well as video interviews of volunteered pupils. The data were analysed both quantitatively using percentages and numerical frequencies and qualitatively employing thematic content analysis. Based on the data, language assessment in primary CLIL is not an established practice. It largely appears to be infrequent, incidental, implicit and based on impressions rather than evidence or the curriculum. The most used assessment methods were teacher observation, bilingual tests and dialogic interaction, and the least used were portfolios, simulations and peer assessment. Although language assessment was generally perceived as important by teachers, a fifth of them did not gather assessment information systematically, and 38% scarcely gave linguistic feedback to pupils. Both pupils and parents wished to receive more information on CLIL language issues; 91% of pupils claimed to receive feedback rarely or occasionally, and 63% of them wished to get more information on their linguistic coping in CLIL subjects. Of the parents, 76% wished to receive more information on the English proficiency of their children and their linguistic development. This may be a response to indirect feedback practices identified in this study. There are several challenges related to assessment; the most notable is the lack of a CLIL curriculum, language objectives and common ground principles of assessment. Three diverse approaches to language in CLIL that appear to affect teachers’ views on language assessment were identified: instrumental (language as a tool), dual (language as a tool and object of learning) and eclectic (miscellaneous views, e.g. affective factors prioritised). LangPerform computer simulations seem to be perceived as an appropriate alternative assessment method in CLIL. It is strongly recommended that the fundamentals for assessment (curricula and language objectives) and a mutual assessment scheme should be determined and stakeholders’ knowledge base of CLIL strengthened. The principles of adequate assessment in primary CLIL are identified as well as several appropriate assessment methods suggested.

Trinexapac-Ethyl and Sulfometuron-Methyl Selectivity to Young Eucalyptus Plants

Trinexapac-ethyl and sulfometuron-methyl are the most widely used ripeners in sugarcane. The application is performed by airborne spraying. Thus, if weather conditions are unfavorable, spray drift to neighboring areas may occur. The objective of this study was to assess the selectivity of the plant growth regulators trinexapac-ethyl and sulfometuron-methyl, used as sugarcane ripeners, to eucalyptus (Eucalyptus urograndis) young plants. The experiment was installed in an eucalyptus commercial yield area, in the municipality of Tambaú, state of São Paulo, Brazil, and arranged in a 2 x 8 factorial design in randomized blocks with four replications. The treatments studied were trinexapac-ethyl and sulfometuron-methyl, sprayed in eight doses, 0; 1.0; 2.5; 5.0; 10; 25; 50 and 100% of the dose used in sugarcane as ripeners (200 g ha-1 of trinexapac-ethyl and 15 g ha-1 of sulfometuron-methyl). Chemical ripeners were applied on eucalyptus plants with 48 cm in height on average; 10.1 branches; 4.5 mm of stem diameter and 44.3 cm of crown diameter, at 46 days after seeding. Trinexapac-ethyl was selective to eucalyptus and stimulated crown diameter growth. At higher doses, sulfometuron-methyl promoted severe noticeable injuries in eucalyptus plants, such as apical bud death. However, during the assessment period the plants recovered and the visual symptoms of phytotoxicity and growth alterations were not observed at 60 days after application. The plant growth regulators trinexapac-ethyl and sulfometuron-methyl were selective to eucalyptus young plants.

Negotiating home and belonging. Young Kurds in Finland

This study looks at negotiation of belonging and understandings of home among a generation of young Kurdish adults who were born in Iraq, Iran, and Turkey and who reached adulthood in Finland. The young Kurds taking part in the study belong to the generation of migrants who moved to Finland in their childhood and early teenage years from the region of Kurdistan and elsewhere in the Middle East, then grew to adulthood in Finland. In theoretical terms, the study draws broadly from three approaches: transnationalism, intersectionality, and narrativity. Transnationalism refers to individuals’ cross-border ties and interaction extending beyond nationstates’ borders. Young people of migrant background, it has been suggested, are raised in a transnational space that entails cross-border contacts, ties, and visits to the societies of departure. How identities and feelings of belonging become formed in relation to the transnational space is approached with an intersectional frame, for examination of individuals’ positionings in terms of their intersecting attributes of gender, age/generation, and ethnicity, among others. Focus on the narrative approach allows untangling how individuals make sense of their place in the social world and how they narrate their belonging in terms of various mechanisms of inclusion and exclusion, including institutional arrangements and discursive categorisation schemes. The empirical data for this qualitative study come from 25 semi-structured thematic interviews that were conducted with 23 young Kurdish adults living in Turku and Helsinki between 2009 and 2011. The interviewees were aged between 19 and 28 years at the time of interviewing. Interview themes involved topics such as school and working life, family relations and language-learning, political activism and citizenship, transnational ties and attachments, belonging and identification, and plans for the future and aspirations. Furthermore, data were collected from observations during political demonstrations and meetings, along with cultural get-togethers. The data were analysed via thematic analysis. The findings from the study suggest that young Kurds express a strong sense of ‘Kurdishness’ that is based partially on knowing the Kurdish language and is informed by a sense of cultural continuity in the diaspora setting. Collective Kurdish identity narratives, particularly related to the consciousness of being a marginalised ‘other’ in the context of the Middle East, are resonant in young interviewees’ narrations of ‘Kurdishness’. Thus, a sense of ‘Kurdishness’ is drawn from lived experiences indexed to a particular politico-historical context of the Kurdish diaspora movements but also from the current situation of Kurdish minorities in the Middle East. On the other hand, young Kurds construct a sense of belonging in terms of the discursive constructions of ‘Finnishness’ and ‘otherness’ in the Finnish context. The racialised boundaries of ‘Finnishness’ are echoed in young Kurds’ narrations and position them as the ‘other’ – namely, the ‘immigrant’, ‘refugee’, or ‘foreigner’ – on the basis of embodied signifiers (specifically, their darker complexions). This study also indicates that young Kurds navigate between gendered expectations and norms at home and outside the home environment. They negotiate their positionings through linguistic repertoires – for instance, through mastery of the Finnish language – and by adjusting their behaviour in light of the context. This suggests that young Kurds adopt various forms of agency to display and enact their belonging in a transnational diaspora space. Young Kurds’ narrations display both territorially-bounded and non-territorially-bounded elements with regard to the relationship between identity and locality. ‘Home’ is located in Finland, and the future and aspirations are planned in relation to it. In contrast, the region of Kurdistan is viewed as ‘homeland’ and as the place of origins and roots, where temporary stays and visits are a possibility. The emotional attachments are forged in relation to the country (Finland) and not so much relative to ‘Finnishness’, which the interviewees considered an exclusionary identity category. Furthermore, identification with one’s immediate place of residence (city) or, in some cases, with a religious identity as ‘Muslim’ provides a more flexible venue for identification than does identifying oneself with the (Finnish) nation.

Rikottujen ikkunoiden nollatoleranssi. Tutkimus New Yorkin rikoksentorjunnan uuskonservatiivi-mallista Suomessa

Väitöskirja on kriminologista kontrollin ja rikoksentorjunnan tutkimusta sekä poliisitutkimusta. Kohteena on ympäri maailmaa levinnyt nollatoleranssiksi kutsuttu järjestyspoliisistrategia. Strategiaa kokeiltiin vuosituhannen vaihteessa vuoden kestäneessä järjestyksenvalvonnan hankkeessa Tampereella. Vaikka kyseessä oli kokeilu, niin tutkimuksessa osoitetaan toimintatavan olleen ja olevan pitkälti kiinteä osa perinteistä suomalaisen järjestyspoliisin toimintaperiaatetta. Artikkeliväitöskirja sisältää viisi vuosina 1998–2005 julkaistua kirjoitusta. Kokoavan yhteenvetoartikkelin tutkimusongelmat ovat seuraavat: Millaisia ovat Yhdysvaltojen ja Suomen järjestyspoliisitoiminnan nollatoleranssien mekanismien, kontekstien ja vaikutusten keskeiset erot ja yhtäläisyydet? Millainen on Tampereen nollatoleranssikokeilu ja New Yorkin rikottujen ikkunoiden nollatoleranssi rikoksentorjunnan arvioinnin ja moraalisäätelyn esimerkkeinä? Tampereen kokeilun prosessi- ja vaikuttavuusarviointitutkimus koostaa tutkimuksen empiirisen aineiston. Hankkeen alku- ja loppumittauksena toimi lomakekysely tamperelaisille (2 x n2000). Lisäksi analyysissä käytettiin kansalaiskyselyn uhrikyselyä, poliisin rikos- ja päivystyskeskustilastoja, Tilastokeskuksen tilastoja, hankkeen suoritelomakkeita sekä rangaistusvaatimus- ja rikesakkolomakkeita sekä kouluterveystutkimuksia. Tampereen poliiseille tehtiin lomakekysely ja teemahaastatteluja. Sosiaali-, nuoriso- ja vapaaehtoistyöntekijöitä sekä yli viisikymmentä tamperelaista nuorta sekä kymmenkunta tamperelaista aikuista haastateltiin. Yhdysvaltojen osalta nojaudutaan verrattain suureen määrään julkaistua korkeatasoista ja ajankohtaista kriminologista tutkimusta. New Yorkiin ja Yhdysvaltoihin sovelletussa hallintavalta- ja moraalisäätelyanalyysissa rikotut ikkunat -teoria osoittautuu uuskonservatiiviseksi moraaliprojektiksi, joka opastaa kaupunkeja hankkimaan itselleen oikeuden tiukkaan järjestyksenvalvontaan. Aiemmin sen oli estänyt kansalaisoikeusmyönteinen lakien tulkinta. New Yorkissa ja Tampereella syntyi useita kielteisiä sivu- ja vastavaikutuksia, kuten ongelmien siirtymistä (displacement). Tämä on yksi keskeinen tulos tilannetorjunnan ja kontrollin tehostamisen ja kohdistamisen hankkeissa. Tulokset haastavat arvioimaan kriittisesti, ovatko kaikki lapsiin ja nuoriin kohdistuvat varhaisen puuttumisen hankkeet seuraustensa perusteella oikeutettuja.
