Background: Human papillomavirus (HPV) causes cervical cancer and external genital warts. The purpose of this study is to document the genotype distribution of HPV in females aged between 18 and 34 who self-referred to an STI clinic with visible external genital warts (EGW). Scrapings were taken from visible external genital warts (EGW). These scrapings were analysed by PCR for the presence of HPV DNA. Positive samples were then genotyped by means of a commercially available assay (LiPA). A comparison of genotyping results determined by the LiPA assay and direct amplicon DNA sequencing was also performed. Results: Ninety-two patients out of 105 samples (88%) had detectable levels of HPV DNA. The majority of individuals with EGW (66%) showed the presence of two or more genotypes. The most common HPV genotypes present in the study population were HPV-6, HPV-11, HPV-16, HPV-18, HPV-33 and HPV-53. Potential effects of vaccination on HPV molecular epidemiology indicate that 40% of the patients could have been protected from the high risk genotypes HPV-16 and HPV-18.Conclusion: This is the first report of the molecular epidemiology of external genital warts in women aged between 18 and 34 from Ireland based on results from a LiPA assay. The study shows that most individuals are infected with multiple genotypes including those with high oncogenic potential and that the newly available HPV vaccines could have a significant impact on prevalence of the most common HPV genotypes in this study population.

Tetradiids are a group of colonial, tubular fossils that occur globally in Middle to Upper Ordovician strata. Tetradiids were first described as a type of tabulate coral; however, based on their four-fold symmetry, division, and presence of a central-sparry canal, they were recently reinterpreted as a florideophyte rhodophyte algae, a reinterpretation that is tested in this thesis. This study focused on understanding the affinity and taphonomy of this order of fossil. Research was conducted by stratigraphic and petrographic analyses of the Black River Group in the Kingston, Ontario region. Tetradiid occurrences were divided into fragment or colonial, with three morphologies of tetradiids described (Tetradium, Phytopsis and Paratetradium). Morphology is specific to depositional environment, with compact Tetradium consistently within ooid grainstones and open branching Phytopsis and chained Paratetradium consistently within mudstones. Two types of patch reefs were recognized: a Paratetradium bioherm, and a Paratetradium, Phytopsis, stromatolite bioherm. The presence of bioherms implies that tetradiids were capable of hypercalcifying. Preservation styles of tetradiids were investigated, and were compared to brachiopods, echinoderms, mollusks, and ooids. Tetradiids were preferentially preserved as molds and demonstrated complete dissolution of skeletal material. Rare specimens, however, demonstrated preserved horizontal partitions, central plates, and a double wall. Skeletal molds were filled with either calcite spar, mud or encrusted by a cryptomicrobial colony. Both calcitic and aragonitic ooids were discovered. The co-occurrence of aragonitic ooids, aragonitic crytodontids, and the evolution of aragonitic, hypercalcifying tetradiids is interpreted as representing the geochemical favoring of aragonite and HMC in a time of global calcite seas. The geochemical favoring of aragonite is interpreted to be independent to global Mg: Ca ratios, but was the result of increased saturation levels and temperature driven by high atmospheric pCO2. Based on the presence of epitheca, tabulae, septa, and the commonality of growth forms, tetradiids are interpreted as an order of Cnidaria. The evolution of an aragonitic skeleton in tetradiids is interpreted to be the result of de novo acquisition of a skeleton from an unmineralized clade.

La Banque mondiale propose la bonne gouvernance comme la stratégie visant à corriger les maux de la mauvaise gouvernance et de faciliter le développement dans les pays en développement (Carayannis, Pirzadeh, Popescu & 2012; & Hilyard Wilks 1998; Leftwich 1993; Banque mondiale, 1989). Dans cette perspective, la réforme institutionnelle et une arène de la politique publique plus inclusive sont deux stratégies critiques qui visent à établir la bonne gouvernance, selon la Banque et d’autres institutions de Bretton Woods. Le problème, c’est que beaucoup de ces pays en voie de développement ne possèdent pas l’architecture institutionnelle préalable à ces nouvelles mesures. Cette thèse étudie et explique comment un état en voie de développement, le Commonwealth de la Dominique, s’est lancé dans un projet de loi visant l’intégrité dans la fonction publique. Cette loi, la Loi sur l’intégrité dans la fonction publique (IPO) a été adoptée en 2003 et mis en œuvre en 2008. Cette thèse analyse les relations de pouvoir entre les acteurs dominants autour de évolution de la loi et donc, elle emploie une combinaison de technique de l’analyse des réseaux sociaux et de la recherche qualitative pour répondre à la question principale: Pourquoi l’État a-t-il développé et mis en œuvre la conception actuelle de la IPO (2003)? Cette question est d’autant plus significative quand nous considérons que contrairement à la recherche existante sur le sujet, l’IPO dominiquaise diverge considérablement dans la structure du l’IPO type idéal. Nous affirmons que les acteurs "rationnels," conscients de leur position structurelle dans un réseau d’acteurs, ont utilisé leurs ressources de pouvoir pour façonner l’institution afin qu’elle serve leurs intérêts et ceux et leurs alliés. De plus, nous émettons l’hypothèse que: d’abord, le choix d’une agence spécialisée contre la corruption et la conception ultérieure de cette institution reflètent les préférences des acteurs dominants qui ont participé à la création de ladite institution et la seconde, notre hypothèse rivale, les caractéristiques des modèles alternatifs d’institutions de l’intégrité publique sont celles des acteurs non dominants. Nos résultats sont mitigés. Le jeu de pouvoir a été limité à un petit groupe d’acteurs dominants qui ont cherché à utiliser la création de la loi pour assurer leur légitimité et la survie politique. Sans surprise, aucun acteur n’a avancé un modèle alternatif. Nous avons conclu donc que la loi est la conséquence d’un jeu de pouvoir partisan. Cette recherche répond à la pénurie de recherche sur la conception des institutions de l’intégrité publique, qui semblent privilégier en grande partie un biais organisationnel et structurel. De plus, en étudiant le sujet du point de vue des relations de pouvoir (le pouvoir, lui-même, vu sous l’angle actanciel et structurel), la thèse apporte de la rigueur conceptuelle, méthodologique, et analytique au discours sur la création de ces institutions par l’étude de leur genèse des perspectives tant actancielles que structurelles. En outre, les résultats renforcent notre capacité de prédire quand et avec quelle intensité un acteur déploierait ses ressources de pouvoir.

Over the past decade, Portugal and Spain received large numbers of immigrants from HTLV-1 endemic areas. Our aim was to investigate the diversity of subtypes circulating in these two countries and the introduction of new variants. We performed a molecular analysis of HTLV-1 strains in patients diagnosed since 1998. LTR and env proviral sequences from 26 individuals were analyzed to generate phylogenetic trees along with reference HTLV-1 subtypes from several geographic origins. Epidemiological and clinical data were recorded. Most subjects were immigrants (57.7%) from South America and Africa. All isolates belonged to the cosmopolitan A subtype. Most carried the transcontinental subgroup A, but five subjects carried subgroup D and one carried subgroup C, previously unreported in Europe. HTLV strains showed separate clusters linked to the patients' geographic origin. Although subjects with HTLV-1 infection tend not to be engaged in high-risk practices, silent dissemination of a broad diversity of HTLV-1 viruses may still occur.

Despite football being deeply entrenched in Scottish culture it is under-researched from a business perspective. This research develops a conceptual framework that views professional football clubs from a number of different perspectives. It draws on strategic management literature since this views the firm as the intersection between internal competence, customer perception and competition within an industry. A review of previous sports business research highlighted five main themes that were used to create a structure for the analysis: on-field performance, attendance, finance, the playing squad and the manager. These themes were used as frames to view the firms within the industry from a number of different perspectives. Each frame allows a different aspect of the firm to be considered singly in turn and then collectively to develop a deeper understanding of the existing frames in use within the industry. The research is based on a pragmatic philosophy that allows mixed methods to be combined to provide both an objective and subjective view of the industry. The subjective view was drawn from five interviews with senior figures within Scottish professional football. These participants were from a number of different roles and organisations within the industry to provide a balance of experiences. The views were triangulated with a descriptive analysis of secondary data from a number of industry sources to establish patterns within and between these frames. A peer group of six clubs was selected as they competed in the Scottish Premier League in each of the seasons within an eleven-year period (2000-2011). The peer group clubs selected were: Aberdeen, Dundee United, Heart of Midlothian (Hearts), Hibernian, Kilmarnock and Motherwell. By focussing on a small group of clubs with a similar on-field record a broad study across the five frames could be carried out in detail without the findings being influenced by the impact of relegation to a lower division or sustained participation in European football. Within each of the original five frames a number of sub-components were identified and linked to the framework; this expanded the content to reflect the findings of this project. There appeared to be little link between on-field performance and attendance although progress to the later stages of cup competitions allowed clubs to connect with fans who do not regularly attend. The relationship between a club’s income and wage bill should be expanded to include interest repayments since this expenditure can be used to highlight future financial problems caused by increased debt levels. Although all of the interview participants spoke with pride of the players that had progressed from the club’s youth academy to success at the highest level the peer group clubs only produced one player each season that played more than ten matches for the club. Almost half of the players signed from the youth academy left the club without playing for the 1st Team. The importance of the relationship between the manager and club chairman was highlighted, although the speed with which managers were appointed suggests that little consideration was given to this before offering a contract. Once appointed there appeared to be little clarity over the job description and areas of responsibility. Several of the interviewees brought experience from other businesses to football but admitted that short-term decision making and entrenched behaviour made change difficult. The conclusion of the research is that by taking a firm-wide view of the club, longer-term decisions can be taken within football. Player development and supporter relationships were both identified as long-term processes that are impacted by the current short-termism. With greater role clarity for managers and a mixture of short and long-term objectives those involved in the industry are more likely to have opportunities to learn from experience and performance, across the different frames, will improve as a result.

The following paper is an action research made with a group of 6 teenagers aged 11-13 from the city of Cali. The project was carried out at a non-formal education institution and basically describes the process of a teaching intervention in which the concepts of Critical Pedagogy and Task-Based Learning were the protagonists. The results show first, that students really need to feel motivated in order to accept a critical approach; second, that the role of the teacher in the achievement of the objectives is extremely relevant; it is necessary for them to have a critical perspective before working on this field besides the constant seeking of information in order to innovate in their classes; third, that the TBL (Task Based Learning) and the critical pedagogy are processes that need some time in order to bear fruits; and fourth, that a needs analysis is essential for the quality of the intervention.

Mass Customization (MC) is not a mature business strategy and hence it is not clear that a single or small group of operational models are dominating. Companies tend to approach MC from either a mass production or a customization origin and this in itself gives reason to believe that several operational models will be observable. This paper reviews actual and theoretical fulfilment systems that enterprises could apply when offering a pre-engineered catalogue of customizable products and options. Issues considered are: How product flows are structured in relation to processes, inventories and decoupling point(s); - Characteristics of the OF process that inhibit or facilitate fulfilment; - The logic of how products are allocated to customers; - Customer factors that influence OF process design and operation. Diversity in the order fulfilment structures is expected and is found in the literature. The review has identified four structural forms that have been used in a Catalogue MC context: - fulfilment from stock; - fulfilment from a single fixed decoupling point; - fulfilment from one of several fixed decoupling points; - fulfilment from several locations, with floating decoupling points. From the review it is apparent that producers are being imaginative in coping with the demands of high variety, high volume, customization and short lead times. These demands have encouraged the relationship between product, process and customer to be re-examined. Not only has this strengthened interest in commonality and postponement, but, as is reported in the paper, has led to the re-engineering of the order fulfilment process to create models with multiple fixed decoupling points and the floating decoupling point system

For older people group music making can assist them remain independent and active in the community. Across Melbourne there are many non-competitive leisure based choirs made of older, active volunteer participants. This paper presents the findings of a phenomenological qualitative case study that was undertaken with members of The Choir of the U3A Hawthorn. This group is auspiced by the international University of the Third Age (U3A) that promotes life-long learning and personal fulfilment amongst older people. In 2008 we began a large joint ongoing research project between Deakin University and Monash University, Well-being and ageing: community, diversity and the arts in Victoria. In 2013 members of the U3A Hawthorn Choir were interviewed about their perceived benefits concerning active music engagement in choir membership. Participants recounted joining the group for different reasons including a positive attitude to singing, convenience, and a desire for social connectedness. Those interviewed considered ongoing choir membership an effective use of leisure time that also provided opportunities for shared learning and personal validation. The data were analysed using Interpretative Phenomenological Analysis and are reported under two themes: Music engagement and Social connections. Membership of the Hawthorn U3A choir provided participants opportunities for friendship, companionship, happiness, a sense of belonging, and acceptance. This resilient community music group (first formed in 1996) has maintained a busy schedule of rehearsals and performances. This music making offers significant ways for older people to maintain well-being and contribute to the wider community.

The 'taste of food' plays an important role in food choice. Furthermore, foods high in fat, sugar and salt are highly palatable and associated with increased food consumption. Research exploring taste importance on dietary choice, behaviour and intake is limited, particularly in young adults. Therefore, in this study a total of 1306 Australian university students completed questionnaires assessing dietary behaviors (such as how important taste was on food choice) and frequency of food consumption over the prior month. Diet quality was also assessed using a dietary guideline index. Participants had a mean age of 20 ± 5 years, Body Mass Index (BMI) of 22 ± 3 kg/m(2), 79% were female and 84% Australian. Taste was rated as being a very or extremely important factor for food choice by 82% of participants. Participants who rated taste as highly important, had a poorer diet quality (p = 0.001) and were more likely to consume less fruit (p = 0.03) and vegetables (p = 0.05). Furthermore, they were significantly more likely to consume foods high in fat, sugar and salt, including chocolate and confectionary, cakes and puddings, sweet pastries, biscuits, meat pies, pizza, hot chips, potato chips, takeaway meals, soft drink, cordial and fruit juice (p = 0.001-0.02). They were also more likely to consider avoiding adding salt to cooking (p = 0.02) and adding sugar to tea or coffee (p = 0.01) as less important for health. These findings suggest that the importance individuals place on taste plays an important role in influencing food choice, dietary behaviors and intake.

A tanulmány a marketing-erőforrások és a vállalatok versenyképessége közötti összefüggéseket elemzi és hasonlítja össze az öt évvel korábbi felmérés eredményeivel. A háromszáz hazai vállalatra kiterjedő kutatás során a szerzők azt állapították meg, hogy a vizsgált marketing-erőforrások mindegyike hatással van a vállalati teljesítményre. Ez annyiban jelent változást az öt évvel korábbi eredményekhez képest, hogy akkor a marketingképességek szerepe még nem volt egyértelmű. Az elemzés során kimutatták, hogy a vállalatok által birtokolt marketing-erőforrások hasonló struktúrát mutatnak, mint korábban. Ezek közül kiemelkedik a marketingfunkcióhoz leginkább köthető piacszervezési dimenzió, amely a legszorosabb összefüggést mutatja a versenyképességgel. A vizsgált vállalatok egy kis csoportjának (12%) sikerült a versenyképes termékkínálat és árak fenntartása mellett e képesség kifejlesztésében és birtoklásában előre lépniük. Körükben a sikeres vállalatok aránya kiemelkedő. --------- The study aimed to analyse the association between marketing resources and corporate competitiveness and it compared the results to the ones of a similar research conducted five years before. Based on the survey of 300 domestic organisations the authors found that all the marketing resources investigated have a significant effect on marketing performance. These results differ from the previous ones only in terms of marketing capabilities, as their role was ambiguous at that time. They revealed the same structure of marketing resources owned by the companies as last time. Among them the most marketing related resource-dimension called market management excels regarding the strength of the association with competitiveness. A small group of the companies investigated (12%) managed to advance in development and possession of this dimension of marketing resources whilst maintaining competitive product supply and price. The proportion of successful companies among them is highly significant
