Aims - This thesis describes an open drug market and its suspected drug users in a Swedish city. This drug market is located at the local bus hub called Navet, in the city of Sundsvall, which has a reputation of being a place to avoid because of the substance abuse and accompanied crime. The aim was to disclose what happens at Navet that is associated with drug related activities. Method - two observers visited Navet from November 2016 to March 2017 at different times of the day with an ethnographic approach to take notes of the daily life at Navet, using their own experiences as basis for the description and analysis. No interactions with the actors at Navet were initiated by the observers. Results - Navet is more than just adrug market, it also provides a meaningful social aspect for the actors by spending time at Navet granting a feeling of belonging to a group. Four different groups of people were identified, the traveling citizens using Navet for transportation, people using navet as their meeting place without taking part of the drug activities, the suspected drug users and the young suspected drug users. The most frequent and openly used substances was alcohol followed by unspecified pills, other types of illegal substances were suspected to be common at Navet but never witnessed to be consumed. Conclusion - As rumored, Navet is a place where drugs and suspected drug users are present during almost all hours of the day. However, the generally perceived feeling of hostility and danger is exaggerated, contributing to a worse reputation of Navet compared to what can be supported through this study. / <p>2017-06-01</p>

The aim of this bachelor thesis was to examine how the reader perceived the media's reporting during #metoo, and if the reader’s trust in Swedish journalism was affected after publishing the names of suspected offenders.  The research questions examined were: How did readers perceive the Swedish media coverage of #metoo? Has the general confidence in Swedish journalism been affected after #metoo? How do the readers perceive Martin Timell today, after he was acquitted of crime? Do the readers think that the name publication of suspected offenders during #metoo was justified?  We used a survey study to investigate our selected research questions. 214 participators took the survey and responded to 9 questions. The image of Martin Timell that was framed in the media in autumn 2017 generally remains, and despite Timell's acquittal of accusations, the reader perceives him as guilty.

No / The purpose was to determine if an age based, local diagnostic reference level for paediatric skeletal surveys could be established using retrospective data. Methods: All children below two years of age referred for a primary skeletal survey as a result of suspected physical abuse during 2017 or 2018 (n ¼ 45) were retrospectively included from a large Danish university hospital. The skeletal survey protocol included a total of 33 images. Dose Area Product (DAP) and acquisition parameters for all images were recorded from the Picture Archival and Communication System (PACS) and effective dose was estimated. The 75th percentile for DAP was considered as the diagnostic reference level (DRL). Results: The 75th percentile for DAP was 314 mGy*cm2 , 520 mGy*cm2 and 779 mGy*cm2 for children <1 month, 1e11 months and 12 < 24 months of age respectively. However, only the age group 1e11 months had a sufficient number of children (n ¼ 27) to establish a local DRL. Thus, for the other groups the DAP result must be interpreted with caution. Effective dose was 0.19, 0.26 and 0.18 mSv for children <1, 1e11 months and 12 < 24 months of age respectively. Conclusion: For children between 1 and 11 months of age, a local diagnostic reference level of 520 mGy*cm2 was determined. This may be used as an initial benchmark for primary skeletal surveys as a result of suspected physical abuse for comparison and future discussion. Implications for practice: While the data presented reflects the results of a single department, the suggested diagnostic reference level may be used as a benchmark for other departments when auditing skeletal survey radiation dose.

The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes. What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child? We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community. The people we interviewed think differently about collaboration. The municipality have different workforms. In the smaller municipality works a social worker at the police station once or twice a week. While in the larger municipality the police and social worker work separately but together nonetheless. The result shows that they are not completely satisfied with the interaction that is today, but it takes a lot of time to build it up and it can always be better. Furthermore, the study shows that the lack of time and resource issues control much of social service work. For the analyzes we have used a theory of interaction. The result shows that the professionals are using the children’s perspective a lot when they are working with children who are suspected of crime.

The purpose of this study was to analyse the tracking systems used to identify patients with tuberculosis who missed a clinic appointment at primary health care facilities in Waterberg District. A quantitative descriptive correlation design was used to determine if there was an association between the tracking systems used and the defaulter rates. Data was collected using a questionnaire with nurses from 46 primary health care facilities, defaulter rates were accessed from the ETR.Net and the two sets of data were correlated. The results showed that the blue folder yielded the lowest mean defaulter rate while the green card yielded the highest mean defaulter rate. Nurses were unaware of the true defaulter rate in their facilities as they underestimated these rates. They therefore did not implement relevant intervention strategies to recall patients or find ways to improve the tracking systems used to reduce the defaulter rate in their health facilities. / Health Studies / M.A. (Health Studies)

In the present investigation peripheral blood lymphocytes from patients with inflammatory bowel disease (IBD) and different cancer states were treated with various agents and compared with lymphocytes from healthy control individuals (HCI) treated in the same way and measured in the Comet assay. For inflammatory bowel disease, patient's responses in IBD patients treated with H2O2 were higher than in HCI and Crohn's patients (CD) were found to have higher responses than Ulcerative colitis (UC) patients. The responses for all IBD and HCI were all reduced in the presence of chaga mushroom extract which behaved in an antioxidant manner. A second group of IBD patients were treated with the heterocyclic amine (food mutagen), IQ and H2O2 and responses were reduced in the presence of the flavonoids, quercetin and epicatechin and compared with HCI similarity treated. In all cells responses were reduced with flavonoids and again CD had higher responses than the UC patients and IBD patients higher than HCI. The responses with CD and UC were that confirmed in two independent studies with IBD, one with chaga mushroom extract and the other with flavonoids. Peripheral lymphocytes from malignant melanoma and suspected melanoma patients and colon cancer and polyposis patients were compared to the lymphocytes from HCI and treated with UVA. There were differential sensitivities when measured in the micronucleus and Comet assays. The cancer patients had higher responses than those in the precancerous states and they in turn were higher than responses in HCI. In all the studies, untreated baseline DNA damage values were also higher in IBD and cancer patients and pre-cancerous patients than HCIs. This would suggest that baseline frequencies of different diseases compared to controls could be an important biomarker in the diagnosis of pre-cancers and early stage cancers. Also peripheral lymphocytes are a useful surrogate for cancers and pre-cancerous disease states since, blood is present in all organs and tissues and DNA is basically the same in all cells.

The phonological system can be described and analyzed on three levels; word, syllable and segment. The non-linear nature of the system enables an analysis from different viewpoints on phonology. LINköpingsUnderSökningen (LINUS) is a phonological test for children between the ages of 3 to 6 years which enables a non-linear analysis. Previous studies at  Linköping University have shown that children with phonological language impairment have phonological deviations on all three levels. Even though there is research involving Swedish-speaking children with expressive phonological impairment, further research is needed due to lacking in sample size and age span of participants. The purpose of this thesis is to compare the expressive phonological ability of children between the ages of 3 to 5 years who have been referred to a speech and language pathologist (SLP) for suspected phonological difficulties with a control group consisting of peers without known difficulties. In the study 10 children participated who were recruited from a speech and language pathologist clinic in a big city in Sweden, and raw data was also used from a previous study on an additional 11 children. Children with language impairment were matched with a control group with children of the same age. The age interval of participating children was between 3 years and 2 months and 4 years and 11 months.  The LINUS test was issued at a speech and language pathologist clinic together with a SLP.  The results showed similar deviations on word, syllable and segment level for both the study group and the control group. However the results of the study group contained a higher amount of deviations. The word and syllable level caused the greatest challenge for both groups. Additionally, both the study group and the control group exhibited deviations in terms of word structure where the most frequent shortcoming was reduction of consonant clusters. To conclude, similar types of deviations occurred in both groups, although the study group had a higher amount of deviations on all levels. For stronger conclusions, a larger sample size and younger participants are needed.

As auditorias em dados financeiros mostram-se limitadas na identificação de fraudes, pois em grande parte, ainda são realizadas com dados coletados por amostragem e incapazes de identificar as situações de delito em tempo real. Este trabalho, visando auxiliar no atendimento a esta lacuna, tem por objetivo propor um método estatístico de monitoramento por Cartas de Controle multivariadas, com base na Lei de Benford, para a detecção de suspeitas de fraude em lançamentos financeiros, entre eles os devidos à lavagem de dinheiro. Foi definido um modelo conceitual com distribuição de probabilidades representando dados oriundos de lançamentos financeiros, e adotada a suposição de que aderem a distribuição da Lei de Benford. Posteriormente foi considerada a distribuição empírica, estimada a partir dos próprios dados e dois procedimentos foram testados para verificar as suspeitas de fraude por lavagem de dinheiro utilizando a avaliação dos primeiros dígitos significativos: A Carta de Controle multivariada _2 e a Carta de Controle multivariada T2 de Hotelling. Foram simulados dados com auxílio do software R-Project até a ocorrência do 50.000o sinal. Foram avaliados casos simulados e reais, com o fim de exemplificar a operação do método. A partir da simulação, as duas Cartas de Controle testadas foram avaliadas quanto ao ARL, isto é, o número médio de observações até sinalizar que a série passou a operar em um estado fora de controle, o que significa a suspeita de lançamentos fraudulentos. Após aplicação do método de análise retrospectiva, com base nas proporções dos primeiros dígitos de Benford em lançamentos financeiros da campanha para Prefeito em 2016, não foram evidenciadas suspeitas de fraude nos dados obtidos junto ao sítio do Tribunal Superior Eleitoral (TSE). Em um conjunto de dados de uma instituição financeira, foram observados sinais de divergência entre as frequências dos primeiros dígitos nos lançamentos e nos valores esperados, porém os pontos além dos limites de controleidentificados encontram-se em um período próximo nas três análises realizadas, concentrando os dados de investigação para a auditoria financeira. A contribuição acadêmica deu-se pelo desenvolvimento de um modelo de aplicação de Cartas de Controle multivariadas e da Lei de Benford, com uma abordagem inovadora do controle estatístico de processos voltado à área financeira, utilizando recurso computacional acessível, de fácil processamento, confiável e preciso, que permite aprimoramento por novas abordagens acadêmicas. No que tange à contribuição à sociedade, se dá pelo uso do modelo por entidades que atuam com movimentações financeiras e pela comunidade, em dados de organizações civis e estatais divulgados nos canais de informação, de modo a proporcionar a prática cidadã pelo acesso à análise e a constatação da idoneidade dos fatos e dos dados. / Large losses are generated in the countryes financial systems, by money laundering. The volume of financial data is big issue to identify digital crime and money laundering. Audits in financial data have limitations in detecting fraud, in large part it is still performed in a traditional way, data are collected by sampling and often unable to identify a real-time crime situation. This research is aiming to serve in addressing this gap, to propose an monitoring statistical method, from multivariate control chart based on Benford’s law for detecting suspicious of fraud in financial data, including those due to money laundering. It was initially defined as a conceptual model in order to determine the type of probability distribution that represents data from financial launches. It was adopted an assumption that this type of data adheres to the Benford’s Law distribution. Subsequently, an empirical distribution was obtained, estimated from the own data. Two procedures were tested to verify a suspected money laundering fraud through the significant first-digit assessment: The Multivariate 2 Control Chart and the Multivariate Hotelling’s T2 Control Chart. Data were simulated using the R-Project software until the occurrence of the 50.000o signal. Finally, the simulation procedures were applied to real data in order to exemplify the method operationally. From the simulation, the two Control Charts tested were evaluated for ARL, that is, average number of observations until the signaling that the series started to operate in an out-of-control state, which it means suspicious of fraudulent launches. The application of the retrospective analysis method in the financial launchings of county’s campaign from 2016 Elections in five capitals of Brazil, based on the expected proportions from the first digit given by Benford’s Law, no suspicions fraud were evidenced in the data obtained from the site of Tribunal Superior Eleitoral (TSE). Considering the application in a set of data from a financial institution, signs of divergence between the frequencies of the first digits of the entries and the expected values were observed, but these points beyond the identified limits are close in all three analyzes. Indicating the period of the data which ones the audit will focus in a further investigation. Academic contribution is identified by developing a multivariate Control Chart together the Benford’s law in an application model with an innovative approach to the statistical process control aimed at the financial area,using accessible, easy to process, reliable and accurate computational resources that allow improvement through new academic approaches. As regard to the contribution to society, it is given the opportunity of applying the model by financial entities and the community in the data of civil and state organizations, disclosed in the information channels in order to provide access to analysis and verification of the suitability of facts and data by citizen practice.
