摘要 犯罪係人類社會長期持續存在的問題,其成因涉及複雜的政治、經濟、思想、文化、教育、人際關係及地理、環境等多方因素型塑而成,也反映出一個社會的病態現象。由於現今社會,顯現出交通日趨便利、資訊快速流通、經濟蓬勃發展、網路世界無遠弗界、社會日益多元開放等特質,由此導致治安情勢日趨複雜,犯罪型態日趨多元、犯罪模式亦隨之變異與難以捉摸,犯罪工具更加精緻,犯罪組織分工更為細緻,犯罪手法更為殘暴、狡黠等,面對此一趨勢,警察人員偵辦刑案之處境,殊值深究。 本研究採取深入訪談法,以13位員警為訪談對象,藉以深入瞭解犯罪狡黠之態樣,探討犯罪狡黠化對員警所造成工作負荷、工作成就之影響,並藉由資深員警的經驗歸納因應對策。研究結果如下: 一、犯罪狡黠、用詞妥適 現行犯罪隨著社會型態的改變而越趨狡黠,以狡黠來形容犯罪尚稱妥適,至於犯罪狡黠的態樣堪稱極其多元。 二、員警負荷、超出預期 由於犯罪越趨狡黠,受訪者之工作負荷有增無減,猶如排山倒海般紛至沓來,相關負荷諸如勤業務繁重、人力不堪負荷,裝備老舊不足等。 三、員警成就、感受不同 在犯罪狡黠之情況下,員警對工作成就的看法,頗多分歧,因人而異,隨著自已的感觸而有所不同。 四、因應對策、多頭併進 犯罪狡黠化所帶來的工作負荷是多元的,因應之道在做法上,可採辦理訓練講習提昇刑案偵辦能力、打擊跨域犯罪、缺額補實強化警察陣容等措施。 五、狡黠犯罪、全面抑制 今日科技產物已淪為犯罪工具、毒品惡瘤再度成為國內萬惡淵藪、暴力犯罪造成社會震撼,跨域犯罪與組織犯罪問題日趨嚴重,企需全面抑制狡黠犯罪。 本研究依據研究結果,提以下建議:一、對警察機關的建議:狡黠用詞可以援引,科技犯罪應嚴予查緝,毒品惡瘤亟待壓制,組織犯罪應逐案控管,因公涉訟確實輔助,因公傷殘落實關懷照護;二、對員警的建議:積極進取,強化專業職能,才能自立自強,對抗狡黠犯罪。 關鍵字:犯罪狡黠化 / Abstract Crimes are persistent in the long history of human society. Their causes are complex due to reasons in politics, economy, thinking, culture, education, human relations, geography and environment. Crimes are shaped by these reasons and also reflect the sickness a society has. In current days, the causes of criminal matters have become even more complicated due to the increasing convenience in transportation, rapid replay of information, the omnipresent Internet and the openness of society. The types of crime have diversified and their patterns have also become more difficult to predict. Crime makers have begun using more refined tools, their organization is highly developed and they've become more violent and sly. In the face of this change, it is a special matter to be given more studies on the environment of police's investigation of crime cases. The research adopts in-depth interview to communicate with 13 police officers. The research wishes to understand the pattern of sly crime makers and also discuss the pressures and influences due to the increasing sly level of them. The research concludes response to these matters with the experiences of senior officers. The results are listed in the following: 1. Sly crimes and proper wording Current crimes types have become slyer with the changes of social pattern. Using 'sly' to describe these cases are quite appropriate and the varieties of crimes are diversified. 2. Officers' burdens are beyond expectation Since the crime makers have become slyer, the pressures of all interviewees have increased. Also, various kinds of pressure accumulate on their shoulders, such as heavy workload, insufficient police officers and antique equipment. 3. Every police officer has his own meaning of achievement As the crimes turn to slyer, police officers have their own definition of achievement in work. Each varies from each other, based on individual sense of feeling. 4. Response strategies should be carried out in various directions The change of crime nature has brought multi-faceted pressure to police officers. To respond to the situation, it is possible to organize training camps to improve crime investigation abilities, break cross-zone crimes and recruit new people to enforce the strength of police. 5. Total crack on sly crimes Current technological products are now used for crime commitment. Drugs are still the source of crimes and violence shocks the whole society. The issues of cross-zone crime and organized crimes are increasingly serious. The police have to crack these sly crimes with a total force. According to the results, the research proposes the following: 1. Suggestions for the police agencies: Use the word sly, strictly investigate technological crimes, crack on drugs, control organized crimes, accusations caused by service should be aided, injuries caused by service should be taken care of, 2. Suggestions to police officers: Be more active, improve professional abilities, be independence and fight against sly crimes. Keywords: Sly crimes

Étude de SLY et de la régulation (épi)génétique des chromosomes sexuels pendant la spermiogenèse / Study of SLY and the (epi)genetic regulation of sex chromosomes during spermiogenesis

Moretti, Charlotte 28 November 2016 (has links)
Globalement réprimés à la méiose (MSCI), les chromosomes sexuels sont partiellement réactivés dans les spermatides rondes avant l’arrêt général de la transcription dans les spermatozoïdes. Alors qu’il est clairement démontré que le MSCI est essentiel pour la poursuite de la spermatogenèse, la proportion de gènes réactivés ainsi que le mécanisme de régulation des chromosomes sexuels après la méiose demeurent un sujet de recherche et de débats. Chez la souris, la délétion du bras long du chromosome Y (MSYq) provoque la surexpression de plusieurs centaines de gènes, dont la majorité est portée par les chromosomes sexuels, associée à des modifications de la chromatine; ceci aboutit à la production de spermatozoïdes malformés et non-fécondants, présentant notamment une compaction anormale de leur chromatine. Sly est un des cinq gènes multicopies du MSYq et l’abolition de son expression chez la souris (souris Sly-KD) a récemment démontré qu’il est à la base de la dérégulation épigénétique des chromosomes sexuels et des problèmes de compaction de la chromatine des mâles MSYq-. De plus, les mâles avec délétion partielle de MSYq ainsi que les mâles Sly-KD produisent une descendance avec un excès de femelles, ce qui suggère l’existence d’un conflit intragénomique avec Slx, un gène multicopie homologue de Sly et porté par le chromosome X. Quel rôle pour SLY pendant la spermiogenèse ? Afin de répondre à cette question nous avons étudié les gènes cibles et les partenaires de SLY. Nous avons montré que SLY interagit avec TBL1XR1, membre inhérent au complexe répressif Ncor. De plus, localisée au niveau des promoteurs de gènes exprimés dans les spermatides et liés aux chromosomes sexuels et autosomaux, SLY contrôle des gènes impliqués dans la régulation génique et chromatinienne (e.g, variants H2A et DOT1L). Nous avons également détecté une baisse significative de la marque H3K79me2 accompagnée d’une rétention anormale des histones dans les spermatozoïdes des souris Sly-KD et proposons que DOT1L, la seule H3K79 méthyltransférase identifiée à ce jour, est essentielle au remodelage de la chromatine. Quels sont les mécanismes moléculaires du conflit intragénomique entre SLY et SLX ? Des expériences de co-immunoprécipitations ont démontré que SSTY, codée comme SLY par un gène multicopies du MSYq, interagit préférentiellement avec SLX in vivo. En outre, SLX et SLY sont capables toutes deux d’interagir avec SPIN1, homologue de SSTY et capable de se lier à H3K4me3. Ces différentes interactions entre SLX/SLY et SPIN1/SSTY pourraient participer au conflit intragénomique. Par la réévaluation de plusieurs jeux de données (RNA-Seq et ChIP-Seq) nous avons démontré que la répression des chromosomes sexuels ne persiste pas au-delà de la méiose et que le conflit intragénomique entre SLY et SLX représente une pression de sélection considérable, en partie responsable du paysage épigénétique spécifique des chromosomes sexuels et de leur enrichissement en gènes multicopies exprimés après la méiose. En conclusion, nos travaux ont permis de caractériser le mode d’action de SLX/SLY et d’identifier de nouveaux facteurs impliqués dans la régulation (épi)génétique pendant la spermiogenèse qui sont conservés chez l’homme. / Sex chromosomes in mammals are globally repressed during meiosis (MSCI ) and then partially reactivated in round spermatids prior to the transcriptional activity shut down occurring in spermatozoa. Whereas the MSCI is essential for spermatogenesis, the proportion of reactivated genes and the underlying mechanisms of the sex chromosomes regulation after meiosis is still a conundrum. In mice, deletions of the long arm of the Y chromosome (MSYq-) are responsible for the overexpression of more than hundred sex chromosome genes associated with epigenetic modifications that leads to impaired sperm functions and abnormal chromatin compaction. Sly is one of the five multicopy genes present on MSYq and Sly deficiency (Sly-KD) has recently been showed to be at the basis of the gene deregulation and sperm defects obrserved in MSYq- mice. Additionally, partially deleted MSYq males and Sly-KD mice produce offspring with a sex ratio distortion in favor of females; these observations suggest a postmeiotic intragenomic conflict involving Sly and its homolog Slx, an X-linked multicopy gene. What role for SLY during spermiogenesis? In order to decipher SLY mechanisms of action, we sought to study SLY target genes and partners. We showed that SLY interacts with TBL1XR1, an inherent member of the repressive Ncor complex. Meanwhile, we found that SLY is enriched at the promoter of spermatid expressed genes encoded both by sex chromosomes and autosomes. Additionally, SLY controls genes involved in genetic and chromatin regulation (e.g, H2A variants and DOT1L). We also observed a significant reduction of H3K79me2 levels associated with abnormal histone retention in Sly-KD spermatozoa. We propose that DOT1L, the principal H3K79 methyltransferase identified to date, is essential for chromatin remodeling in spermatids. What are the molecular mechanisms involved in the ongoing intragenomic conflict between SLY and SLX? We showed by co-immunoprecipitation that SSTY, another Y-linked multicopy gene, preferentially interacts with SLX in vivo. Furthermore, both SLX and SLY interact with SPIN1, a homolog of SSTY which is able to recognize H3K4me3. The interactions between SLX/SLY and SPIN1/SSTY could be part of the intragenomic conflict. By re-evaluating several RNA-Seq and ChIP-Seq datasets we demonstrated that MSCI does not persist beyond meiosis. We proposed that the intragenomic conflict between SLY and SLX constitutes a considerable selection pressure, partly responsible for the specific epigenetic landscape of sex chromosomes and their enrichment in multicopy genes expressed after meiosis. In conclusion, our work allowed a better understanding of the mode of action of SLX/SLY and the identification of new factors involved in the (epi)genetic regulation during spermiogenesis that are conserved in humans.

Om Sly : En utforskande designprocess av ett naturmaterial och formgivning.

Modin, Victor January 2019 (has links)
Materialet sly står i centrum i mitt examensprojekt. Som student på Konstfack och i min framtida yrkespraktik har frågor om cirkulär ekonomi och cirkulär design varit närvarande. Det är avgörande för att påverka samtiden och framtiden mot en mer hållbar framtid. Sly är en resurs, ett material som både finns lokalt, regionalt och nationellt. Jag har arbetat med ett material från naturen som av tradition har betraktas ha ett lågt ekonomiskt värde. Syftet var att se om materialet kan förädlas och användas som råvara i produktutveckling och produktdesign. Vidare arbetar jag i en ämnesfråga där begrepp som cirkulär design och biologisk, social och ekologisk hållbarhet är centrala. Projektet rör sig i ämnesfält som bioekonomi, cirkulär design och frågor om lokal produktion.
