Den svenska polismyndigheten påbörjade den 1 januari 2015 genomförandet av den största omorganisationen på 50 år. Polisen gick från 23 enskilda myndigheter till en nationell, en enrådsmyndighet. Omorganisationen kunde enligt regeringen ge goda förutsättningar för att uppnå de mål och krav som finns för myndigheten, men skulle också leda till större enhetlighet för Polisen. Att ombilda myndigheten till en enårdsmyndighet skulle enligt regeringen också bidra till en “rättssäker, kvalitativ och kostnadseffektiv verksamhet” med jämna resultat. Syftet med reformen var således att uppnå “högre kvalitet, ökad kostnadseffektivitet, ökad flexibilitet och väsentligt förbättrade resultat i polisens verksamhet”. Eftersom mycket missnöje riktats mot reformen, både internt och externt, har ett stort intresse väckts hos oss. Syftet med vår studie är därför att undersöka hur myndigheten samt anställda inom Polisen upplevt och påverkats av reformen. Frågeställningar för vår studie är: ·     Hur upplevs Polismyndighetens omorganisation av anställda? ·     Kan  det  finnas  några  externa  händelser  respektive  omständigheter  som  påverkat reformen i en viss riktning? ·     Hur ser Polisens organisationskultur ut och hur präglar denna kultur myndigheten? ·     Finns det grupper/medarbetare inom myndigheten som påverkats mer än andra av omorganisationen? Studien genomförs utifrån perspektiv om organisationsförändringar, organisationskulturer, samt mål- och resultatstyrning.

Syftet med denna studie var att skapa förståelse för komplexiteten av att beskriva arbetsplatsrelaterat hot respektive våld mot poliser som arbetar i särskilt utsatta områden, med utgångspunkt i den begreppsmässiga problematiken. Genom semi-strukturerade intervjuer med fem poliser som arbetar i särskilt utsatta områden fann vi att det råder en begreppsförvirring avseende arbetsplatsrelaterat hot respektive våld. Det framkom att hot var mer svårdefinierat än våld samtidigt som det var möjligt att identifiera en ambivalens som påvisade att inget av begreppen erhöll en självklar definition. Definitionen baserades dels på vilka uttryck och handlingar som inkluderades respektive exkluderades, dels på vem som sätter gränserna för hot respektive våld. Definitionen baserades även på vem som utför handlingarna. Studiens viktigaste slutsats var att det inte med säkerhet bör gå att dra slutsatser kring omfattning och karaktär utan att ta hänsyn till den begreppsmässiga problematiken som råder avseende arbetsplatsrelaterat hot respektive våld i särskilt utsatta områden. / The purpose of this study was to create an understanding regarding the complexity of describing workplace violence against police officers who work in particularly vulnerable areas, based on the definitional problem. Through semi-structured interviews with five police officers who work in particularly vulnerable areas, we found that there is a definitional confusion regarding workplace violence. It emerged that threats were more difficult to define than violence, while it was possible to identify an ambivalence that showed that none of the concepts received a definite definition. The definition was based partly on which expressions and actions were included and excluded, respectively, on who sets the boundaries regarding threat and violence, but was also based on who is performing the actions. The main conclusion of the study was that it may not be possible to draw conclusions about range and character with certainty, without taking into account the definitional problem that prevails regarding workplace violence in particularly vulnerable areas.

The propolis extract can be obtained by supercritical fluid extraction using CO2 as solvent, which is a clean and non-toxic technology, leaving no residue. This work aims to extract chemically and biologically extracts of green and red propolis produced by bees of the species Apis mellifera. Supercritical CO2 extraction from the raw propolis and its ethanolic extracts, which were impregnated in filter papers, were performed. The pressures used for fractionation of raw propolis were 90, 120, 150, 200, 250 and 300 bar and, for the propolis impregnated in filter papers, 90, 150 and 300 bar. For comparison of the chromatographic profiles at different pressures, chemical analysis using Thin Layer Chromatography (TLC) and High Performance Liquid Chromatography (HPLC) were done. The chemical composition of the extracts from impregnated propolis ethanolic extracts (PEE) and raw propolis remained similar, but the yield of supercritical extracts from impregnated PEE in filter papers showed much higher values. Supercritical extracts showed antifungal activity and excellent antioxidant activity. / A pr?polis ? uma subst?ncia resinosa produzida pelas abelhas atrav?s da coleta de metab?litos secund?rios da flora e sua composi??o qu?mica ? complexa e variada, conferindo a este produto diversas atividades biol?gicas como antibacteriana, antif?ngica e antioxidante. O extrato da pr?polis pode ser obtido por extra??o supercr?tica, utilizando CO2 como solvente, sendo esta uma tecnologia limpa, at?xica e que n?o deixa res?duo. Este trabalho tem como objetivo extrair e avaliar quimicamente e biologicamente extratos de pr?polis verde e vermelha produzidos pelas abelhas da esp?cie Apis mellifera. Foram realizadas extra??es com CO2 supercr?tico a partir da pr?polis bruta e de seus extratos etan?licos, os quais foram impregnados em pap?is filtro. As press?es utilizadas para fracionamento da pr?polis bruta foram 90, 120, 150, 200, 250 e 300 bar, e da pr?polis impregnada em pap?is filtro, 90, 150 e 300 bar. Para compara??o dos perfis cromatogr?ficos nas diferentes press?es, an?lises qu?micas atrav?s de cromatografia em camada delgada (CCD) e cromatografia l?quida de alta efici?ncia (CLAE) foram realizadas. A composi??o qu?mica dos extratos a partir dos extratos etan?licos de pr?polis (EEP) impregnados e da pr?polis bruta permaneceu similar, por?m o rendimento dos extratos supercr?ticos a partir dos EEP impregnados em pap?is filtro apresentou valores muito mais elevados. Os extratos supercr?ticos obtidos apresentaram atividade antif?ngica e excelente atividade antioxidante.

The public realm of the ancient, Western city evolved situationally - over time and in response to the ethos of its citizens. Some of the urban forms that were born within the context of the ancient city are still in use today. These now archetypal forms met the specific needs of the ancient city, and as they were repeated, patterns arose that came to define what a physical city was. The physical form of the city and the citizen body were intrinsically linked in the ancient world - and in ancient Greece were defined by the same word - polis. In Rome, the city and the collective citizenry come to be defined separately - as urbs and civitas, respectively. The Romans continue to use and elaborate upon the urban forms and patterns developed in Greece, in support of the Roman civitas. The development of the public realm and its most archetypal forms, from the stoa to the public plaza, of a selection of ancient cities will be examined in three parts; Greece, Rome, and Roman colonies. Within these three representative examples, a tripartite examination of the myths, rituals, and development of the public realm will give a complete picture of the city - its form and its ethos. First, the Greek city will be discussed using the architectural development of the Athenian agora within its historical and political context. With an understanding of the Greek public realm, specific architectural advancements, including the stoa form, of the Greeks can be better understood. Second, the Roman elaboration of the Greek forms will be traced in the growth of the Forum Boarium in Rome. While situationally-developed, the archetypal urban forms that grew in Greece and Rome came to define urban patterns that could be used in new settings, like those of colonial settlements, while retaining the ethos of the original. From its first colony of Ostia to its exemplary Gallic capital of Lyon, Rome established a codified set of urban patterns that both represented and explained Roman urban values to its expanding populace. Finally, the Roman contributions, particularly the colony and fora patterns that evolved in Gaul, will be examined in detail using the colonial capital of Lyon as the primary example. As new socio-political systems evolved - the polis in Athens and the Empire in Rome - correlating urban forms developed in support of them. In the ancient city, the city and the public realm were the containers for ritual action - and the architecture that developed reflected this basic purpose of the city.

Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico - CNPq / Propolis is a resinous material collected by bees from different parts of plants. Both its composition as its biological properties are dependent on factors such as climate, soil, vegetation and species of collecting bees. Propolis has great potential for therapeutic use due to its chemical composition and pharmacological properties. Herein it was determined the contents of phenolic compounds, antioxidant capacity and chemical composition (assessed by HPLC-PAD) of twelve green propolis samples from beekeepers and sixteen commercial propolis extracs from different regions of Southeast Brazil. The antioxidant abilities of the extracts were qualitatively determined through the total phenolic contents using the Folin?Ciocalteau method. Total flavonoids were assessed by the method of complexation with aluminium chloride. The quantitative antioxidant activiti of propolis extracts were determined both by trapping the organic radicals DPPH and ABTS.+ as well by the iron reduction method (FRAP). High pressure liquid chromatography allowed the identification and quantification of chlorogenic acid, caffeic acid, ferulic acid, para-coumaric acid, rosmarinic acid, vanillin, hesperidin, naringenin, pinobanksin, kaempferol, 4-hydroxy-3,5-diprenyl cinnamic acid (Artepillin-C), kampheride and pinostrobin. Artepillin C, a well known chemical marker of propolis, was present in all propolis extracts analyzed. We highlight that the presence of rosmarinic acid in propolis samples from Rio de Janeiro was reported for the first time in this work. The discrimination between green propolis in natura and commercial green propolis extracts was performed using PCA (Principal Component Analysis) statistical method. The antioxidant capacity in vivo of propolis extracts were evaluated using Saccharomyces cerevisiae as biological system model, assessing important parameters as stress tolerance and lipid peroxidation rate. The antifungal activity of ethanol extracts of propolis in natura were tested against the phytopathogenic fungus Fusarium oxysporium. / A pr?polis ? um material resinoso coletado pelas abelhas de diferentes partes das plantas, sua composi??o e as suas propriedades biol?gicas dependem do clima, solo, vegeta??o e da esp?cie da abelha. A pr?polis tem grande potencial de aplica??o terap?utica, devido ? sua composi??o e propriedades farmacol?gicas. Nesse trabalho foi determinado o teor de subst?ncias fen?licas, a capacidade antioxidante e composi??o qu?mica por CLAE-DAD de doze amostras de pr?polis verde, adquiridas de apicultores, e dezesseis extratos de pr?polis comerciais, provenientes de diferentes regi?es do Sudeste do Brasil. A capacidade antioxidante dos extratos foi avaliada qualitativamente atrav?s do teor de fen?licos totais, pelo m?todo de Folin?Ciocalteau, e flavonoides pelo m?todo de complexa??o com cloreto de alum?nio. A quantifica??o do potencial antioxidante foi realizada pela captura dos radicais org?nicos DPPH e ABTS.+, al?m do m?todo de redu??o do ?on f?rrico (FRAP). An?lises por cromatografia l?quida de alta efici?ncia permitiram a identifica??o e quantifica??o de ?cido clorog?nico, ?cido cafeico, ?cido fer?lico, ?cido para-cum?rico, ?cido rosmar?nico, ?cido 3,5-diprenil-4-hidroxicin?mico (Artepillin C), vanilina, hesperidina, naringenina, pinobanksina, canferol, canferide e pinostrobina. Em todos os extratos de pr?polis analisados foi identificado o Artepillin C, marcador qu?mico para pr?polis verde. Destacamos que neste trabalho foi reportada pela primeira vez a presen?a de ?cido rosmar?nico em pr?polis do Rio de Janeiro. M?todos quimiom?tricos de an?lise explorat?ria, utilizando ?nalise por Componentes Principais foram utilizados para discriminar extratos de pr?polis verde in natura daqueles extratos comerciais. O potencial antioxidante in vivo dos extratos etan?licos de pr?polis foram avaliados utilizando cepas controles de Saccharomyces cerevisiae como modelo de sistema biol?gico e foram avaliados toler?ncia ao estresse e proxida??o lip?dica. A atividade antif?ngica dos extratos etan?licos de pr?polis in natura foram avaliados, e inibiram o crescimento in vitro do fungo fitopat?geno Fusarium oxysporum.

This research aims: i) to provide the acoustic description of the sibilant fricatives produced in Porto Alegre/RS and Florian?polis/SC in onset and coda; ii) to investigate the effects of the linguistic bias (contrastive and non-contrastive function of sibilant fricatives) on the phonetic perception of sibilant fricatives in onset and coda; and iii) to investigate the effects of the cognitive bias on the perception of phonetic variation of sibilant fricatives in coda. The corpus of this study consists of two samples of production data, one referring to data from 16 informants from Florian?polis and another sample referring to data from 24 informants from Porto Alegre. Regarding the perception data, the sample collected in Florian?polis consists of 30 participants, while the sample collected in Porto Alegre consists of 10 participants. The acoustic analysis of the sibilant fricatives partially confirmed the predicted coarticulatory effects of the surrounding vowel contexts and the effects of syllable stress on the spectral characterization of the sibilant fricatives, except for the vowels [u] and [o] preceding the fricative sibilant in coda and the unstressed pretonic syllable in the case of the alveolar fricative in onset. It seems that the variability of the phonetic production correlates with the gender of the speakers in the two cases indicated. The gender of the speakers also seems to interfere in the production of the alveolar fricative in onset by more educated people from Porto Alegre, with men tending to increase the Centroid, while women tend to reduce it. The temporal parameter examined showed a constant effect, namely the increase of frequencies as a function of the duration of the sibilants in onset and coda. The increase in frequencies due to the monitored speech style has also been confirmed and it is suggested to be an articulatory behavior associated specifically to women. Concerning the analysis of perception data, contrast and noncontrast relations of sibilant fricatives do affect the perception of men and women from Florian?polis and men from Porto Alegre, but not in the perception of women from Porto Alegre. Regarding the perception of phonetic variation, the results suggest that automatic associations between the stereotype of native/local resident and the palatoalveolar fricative in Florian?polis and the association between the stereotype of portoalegrense and the alveolar fricative in Porto Alegre are activated during perception. Moreover, the implicit association tends to become stronger as participants overtly report a greater difference between alveolar and palato-alveolar stimuli. However, the fact that some participants associate this difference to linguistic aspects other than the sibilant fricative in coda shows that the perception of socially structured phonetic variation occurs unconsciously. It is therefore concluded that the production of voiceless sibilant fricatives in Brazilian Portuguese is phonetically gradient and varies according to the gender of the speakers and that the perception of these sounds is mediated by linguistic and cognitive biases. / Esta tese trata da produ??o e percep??o das fricativas sibilantes n?o-vozeadas [s] e [?] em ataque e coda sil?bica nas variedades de portugu?s brasileiro faladas em Porto Alegre/RS e Florian?polis/SC sob a perspectiva da Sociofon?tica (FOULKES; DOCHERTY, 2006; FOULKES; SCOBBIE; WATT, 2010; THOMAS, 2011). A pesquisa teve como objetivos: i) realizar a descri??o ac?stica das fricativas sibilantes produzidas em Porto Alegre/RS e Florian?polis/SC em ataque e coda sil?bica; ii) investigar os efeitos do vi?s lingu?stico (fun??o contrastiva e n?o-contrastiva das fricativas sibilantes) sobre a percep??o fon?tica das fricativas sibilantes em ataque e coda sil?bica; e iii) investigar os efeitos do vi?s cognitivo sobre a percep??o da varia??o fon?tica das fricativas sibilantes em coda sil?bica. O corpus deste estudo contou com duas amostras de dados de produ??o, a saber, uma amostra referente a dados de 16 informantes florianopolitanos e outra amostra referente a dados de 24 informantes porto-alegrenses. Quanto aos dados de percep??o, a amostra florianopolitana ? constitu?da por 30 participantes, ao passo que a amostra portoalegrense conta com 10 participantes. A an?lise ac?stica das fricativas sibilantes confirmou parcialmente os efeitos coarticulat?rios dos contextos voc?licos circundantes e da tonicidade sobre a caracteriza??o espectral das fricativas sibilantes, exceto pelas vogais [u] e [o] em contexto precedente ? sibilante em coda e pela tonicidade pret?nica no caso da fricativa alveolar em ataque. Ao que parece, a produ??o fon?tica vari?vel se correlaciona com o g?nero dos falantes nos dois casos indicados. O g?nero dos falantes tamb?m parece interferir na produ??o da fricativa alveolar em ataque pelos porto-alegrenses que possuem n?vel Superior de escolaridade, sendo que os homens tendem a aumentar o Centroide, enquanto as mulheres tendem a reduzi-lo. O par?metro temporal examinado apresentou um efeito constante, a saber, o aumento das frequ?ncias em fun??o da dura??o das sibilantes em ataque e coda. O aumento das frequ?ncias em fun??o do estilo de fala monitorado tamb?m se confirmou e sugere se tratar de um comportamento articulat?rio associado especificamente ?s mulheres. No que diz respeito ? an?lise dos dados de percep??o, as rela??es de contraste e de n?o-contraste das fricativas sibilantes de fato interferem na percep??o dos homens e mulheres florianopolitanos e dos homens portoalegrenses, mas n?o na percep??o das mulheres porto-alegrenses. Em rela??o ? percep??o da varia??o fon?tica, os resultados sugerem que associa??es autom?ticas entre o estere?tipo de morador nativo e a fricativa palato-alveolar em FLN e entre o estere?tipo de porto-alegrense e a fricativa alveolar em POA s?o ativadas durante a percep??o. Mais do que isso, a associa??o impl?cita tende a se tornar mais forte conforme os participantes reportam explicitamente uma diferen?a maior entre os est?mulos alveolar e palato-alveolar. Todavia, o fato de que alguns participantes relacionam essa diferen?a a outros aspectos lingu?sticos que n?o ? fricativa sibilante em coda evidencia que a percep??o da varia??o fon?tica socialmente estruturada ocorre de modo inconsciente. Conclui-se, portanto, que a produ??o das fricativas sibilantes n?o-vozeadas do portugu?s brasileiro ? foneticamente gradiente e varia em fun??o do g?nero dos falantes e que a percep??o desses sons ? mediada por vieses lingu?sticos e cognitivos.

<p>This licentiate thesis builds on the assumption that there is a shift in professional perspective when a police officer takes on the task of a police teacher in the Police Basic Education Training Programme.

The analysis is built on theories from George Herbert Mead, Moira von Wright, and Ludwik Fleck about the importance of in-tersubjective interaction in the interpersonal or social perspective of construction knowledge about oneself as a subject and the surrounding world. Professional identity is defined as the way, consciously or unconsciously, an individual under-stands oneself as a professional; it is seen as an ongoing process shaped by con-tinuous intersubjective meetings with others in a changeable world.

The development of new professional and personal knowledge is due to the ability to reflect on the outcome of the intersubjective meetings with students and other teachers. This change of professional identity of the police teachers complicates their mission in two aspects. First, the denial of the relationship with the students as colleagues could be in conflict with the expectation from the stu-dent police officers. Secondly, the gap in knowledge about police work between the reflected personal knowledge of the police teachers and the student police offi-cers’ knowledge built on movies and books makes it difficult to meet the students at their level. This situation demands opportunities for police teachers to discuss their tasks with other teachers on campus, in the context of intersubjective meet-ings.</p>

<p>SAMMANFATTNING</p><p><p>Ländryggsbesvär är generellt vanligt förekommande i befolkningen och samhällsekonomiskt kostsamt. Riskfaktorer för ländryggsbesvär beskrivs vara flerdimensionella, där nämns främst arbetsrelaterade och psykosociala faktorer. Poliser är en yrkesgrupp där arbetssjukdomar rapporteras vanligt förekommande oavsett kön. Trots det är polisers arbetssituation dåligt utforskad. Syftet med studien är att kartlägga upplevt hälsotillstånd och arbetssituation bland utryckningspoliser med fokus på ländryggsbesvär, som underlag för preventiva åtgärder. Metoden bestod av en tvärsnittsstudie i form av en omfattande enkätundersökning. Urvalet inom polisens utryckningsenhet i Västerås var totalt. Så många som 60 % angav arbetsrelaterade ländryggsbesvär, en större del med besvär var män och förekomst av tunga lyft var vanligare bland svarande med besvär. Personer med ländryggsbesvär tog i mindre utsträckning pauser, kände sig stressade på arbetet och besvärades oftare av kroppslig värk. Deltagarna själva kopplade sina ländryggsbesvär till dåligt utformad arbetsutrustning, dålig sittställning i yrkesfordonen och till fysiska ingripanden. Av litteraturen beskrivna riskfaktorer för ländryggsbesvär var vanligt förekommande inom enheten. Där nämns ogynnsamma arbetsställningar och arbetsmoment samt psykosociala faktorer i form av hög arbetsbelastning, lågt stöd från arbetsledning och låg möjlighet att påverka sin arbetssituation.</p><p>Slutsats: För att förbättra arbetsmiljön för utryckningspoliser bör åtgärder inriktas mot belastningsergonomiska- och psykosociala faktorer i arbetet samt utformning av utrustning och arbetsfordon utifrån ergonomi och säkerhet.</p></p> / <p>ABSTRACT</p><p>Low back pain is a common disorder which causes high economic costs for the society. Risk factors for back pain are described as multidimensional, including both work related and psychosocial factors. Police-officers belong to an occupational group were work related diseases are frequently reported, irrespective of gender. The work situation for these officers however is poorly covered by targeted research. The purpose of this study is to survey the health- and work situation among police-officers with the focus on low back pain. The hope is that the results can be used as a base for preventive interventions. A cross sectional design with an extensive survey was used for the study. The selection was total within the unit of patrolling police officers in Västerås. As many as 60 % reported low back pain, with an overrepresentation among men. Heavy lifting was more common among those with low back pain. Those reporting low back pain more rarely took breaks during the work day, they felt more stressed at work and were more often troubled with physical pain. The study participants linked their back problems to badly designed work equipment, badly adjusted vehicles and to physical interventions. Risk factors for low back pain, described by the literature, were common within the unit. Especially, work tasks involving unfavorable movements and body positions were singled out. Among psychosocial factors, low social support from management and low ability to influence the work situation were associated with low back pain.</p><p>Conclusion: To improve the work environment for patrolling police-officers, measures should be focused on load and strain ergonomics, psychosocial factors as well as to develop equipment and vehicles more on the basis of ergonomics and safety measures.</p>

Övergripande diskuterar avhandlingen olika aspekter av att samhällets system av stöd och kontroll för barn och unga knyts närmare samman. Det handlar om hur samverkan framställs och uppfattas på olika nivåer och hur den konkretiseras i polisens och socialtjänstens arbete kring unga som utvecklat eller bedöms riskera att utveckla kriminalitet och/eller missbruk. Studieobjektet inbegriper övergripande ideologisknivå, lokal/praktisknivå och individuell nivå. Syftet med avhandlingen är att identifiera, beskriva och analysera polisens och socialtjänstens samverkan kring barn och ungas kriminalitet och missbruk. Utgångspunkten är hur; samverkan mellan myndigheterna framställs i offentliga dokument, hur lokala aktörer uppfattar behovet av men också möjligheter, svårigheter och hinder kring samverkan, hur myndigheterna lokalt är organiserade för att aktualisera, handlägga, behandla och avsluta barn och unga, och slutligen vilka barn och unga som denna samverkan kan omfatta. Avsikten är att få en bild av vad denna samverkan på policynivå innebär och sätta detta i relation till hur polis och socialtjänst förstår och skapar sina respektive och gemensamma uppdrag i förhållande till varandra lokalt.  I avhandlingen används tre olika empiriska material och olika metoder för analys: Analys av statliga offentliga dokument, kvalitativa intervjuer med poliser, socialarbetare och deras chefer i en kommun och en kvantitativ kartläggning av aktuella ungdomar i kommunen. Handlingsnät som teoretisk grund används för att studera kopplingar mellan de båda myndigheterna och de tre olika nivåerna av studien.  Genom att använda handlingsnät blir det möjligt att se hur polisens och socialtjänstens olika uppdrag kopplas samman kring barn och ungas kriminalitet och missbruk. Resultaten av studien visar att det pågår en ettablering av ett socio-polisiärt handlingsnät på den övergripande ideologiska nivån och den lokala kommunala nivån.  I policydokumenten förspråkas ett kontrollerande förhållningsätt gentemot ungas kriminalitet. På den lokala nivån handlade det om ett kontrollstödjande förhållningsätt för att motverka både ungas kriminalitet och missbruk.  Resultaten av studien visar att socialtjänsten fått ta ett större ansvar för att utreda och verkställa påföljder för ungas kriminella handlingar, samtidigt som det inom socialtjänsten riskerar att utvecklas en logik mera baserad på straffvärdet av den brottsliga handlingen än den unges individuella behov av hjälp och stöd.    Studien visar att i polisens och sociatjänstens arbete med enskilda barn och unga finns få möjligheter till samarbete. Dessutom var det få unga personer som samtidigt var aktuella för både polis och socialtjänst, vilket gör det svårt att uppnå något djupare längre samarbete kring enskilda ungdomar under längre tid. Det kan i bästa fall mera handla om en form av remissförfarande från polis till socialtjänst. / This thesis discusses different aspects of the link between social support and control systems for children and young people. By analysing the ideas and practice, it opens up a critical perspective in understanding collaboration between police and the social services. This study seeks knowledge about how collaborative forms are officially presented and perceived at different levels and how they are realised in the police’s and social services’ work with young people who have developed or at risk of developing criminal behaviour and/or substance abuse. The object of the study embraces the overarching ideological, local/practical and individual levels. The purpose is to identify, describe and analyse police and social service collaboration with regard to crime and substance abuse among children and young people. It addresses the following questions: How are collaborative concepts formulated in public documents in relation to the causes and problems that the collaboration is expected to resolve? What are local actors’ perceptions of collaboration? How do the police authorities and social service departments at the local level organise their activities to prevent young people’s criminality and substance abuse? How many children and young people are estimated to be involved in either the police authority, the social services department, or both? The study’s starting points are: how inter-agency collaboration is portrayed in public documents; how local actors perceive the need for – but also the possibilities, difficulties and obstacles associated with – collaboration; how the agencies are organised locally for observing, administrating, and treating children and young people and deciding when the young person requires no further attention; and finally which children and young people are subject to this collaborative work. The thesis consists of three studies using different empirical material and different methods of analysis: policy analysis of public documents, qualitative interviews with social workers, police officers and their managers in a municipality and a quantitative mapping exercise.  Actor-network theory is used to understand how actions are connected between organizations and between the three levels of the study. Using the concept actor-network it is possible to show how police and social service commitments are linked. The results of the thesis show that there was an establishment of a socio-police actor-network both at an ideological and a local level. The main idea, expressed in the official documents was that there should be a controlling attitude towards youth crime. At a local level the main ideas among those interviewed was that they had both a controlling and supportive attitude to youths, with both crime and abuse problems. It is possible that the social services logic has changed from values based on individual needs to values based on punishment. The study also showed that in practice there were just a small number of young people who were current for both the police and social services at the same time.

This licentiate thesis builds on the assumption that there is a shift in professional perspective when a police officer takes on the task of a police teacher in the Police Basic Education Training Programme. This shift of perspective is described as a professional process as well as a learning process, and the investigation focuses the reshaping of one’s professional identity. The investigation is based on focus group interviews with four different groups of police teachers in Växjö, Stockholm, and Umeå, where they were asked to talk about their task as police teachers. The analysis is built on theories from George Herbert Mead, Moira von Wright, and Ludwik Fleck about the importance of in-tersubjective interaction in the interpersonal or social perspective of construction knowledge about oneself as a subject and the surrounding world. Professional identity is defined as the way, consciously or unconsciously, an individual under-stands oneself as a professional; it is seen as an ongoing process shaped by con-tinuous intersubjective meetings with others in a changeable world. Professional, personal and possibly tacit knowledge is in that aspect developed and may be pos-sible to articulate in the right environment, for example within focus groups. The findings indicate that the change of professional task of the police teachers affects their understanding of themselves as professionals, i.e., their professional identity. The development of new professional and personal knowledge is due to the ability to reflect on the outcome of the intersubjective meetings with students and other teachers. This change of professional identity of the police teachers complicates their mission in two aspects. First, the denial of the relationship with the students as colleagues could be in conflict with the expectation from the stu-dent police officers. Secondly, the gap in knowledge about police work between the reflected personal knowledge of the police teachers and the student police offi-cers’ knowledge built on movies and books makes it difficult to meet the students at their level. This situation demands opportunities for police teachers to discuss their tasks with other teachers on campus, in the context of intersubjective meet-ings.
