Pneumocystis-carinii-Pneumonie bei Säuglingen mit vertikaler HIV-Infektion in der Schweiz [Pneumocystis carinii pneumonia in infants with vertically acquired HIV infection in Switzerland]

OBJECTIVE: Review of incidence, clinical picture, therapy, and outcome of Pneumocystis carinii pneumonia (PCP) in infants with vertically-acquired HIV infection in Switzerland. METHODS: Inquiry among members of the Swiss Pediatrics AIDS Group, review of the data base of the Swiss Neonatal HIV Study and retrospective analysis of the charts from infants with PCP. RESULTS: Since 1986 PCP has been diagnosed in 10 out of 107 infants with vertically-acquired HIV infection. PCP occurred in 7 infants at the age of 3-6 months and in 3 at the age of 9-11 months. 4 infants showed symptoms related to HIV infection before developing PCP. Before the development of PCP, infection with HIV had been ascertained in 6 infants. In 2 the diagnosis was still unclear and in the 2 remaining the risk of HIV infection was not known. None of the infants was on primary prophylaxis against PCP. Signs and symptoms of PCP included cough and tachypnea (100%) as well as high fever up to 40 degrees C (90%). Transcutaneous oxygen saturation was 70-95%. Chest X-rays revealed interstitial infiltrates in 6 infants, localized infiltrates in 2 and interstitial as well as localized infiltrates in 2. The CD4+ cell count was, with one exception, < 1500/microliters, i.e. below the normal value for age. Side effects of high dose cotrimoxazole were noted in 6 patients. 5 infants required intubation and mechanical ventilation. 4 infants died due to PCP, including 3 of those who required intubation and mechanical ventilation. CONCLUSIONS: PCP in infants with vertically-acquired HIV infection preferentially occurs at the age of 3 to 6 months and is often lethal, especially in patients requiring intubation. Evaluation for HIV infection should be done as early as possible in order to introduce primary PCP prophylaxis in infants at risk for this opportunistic infection.

JXTA security in mobile constrained devices

JXME is the JXTA protocols implementation formobile devices using J2ME. Two different flavors of JXME have been implemented, each one specific for a particular set of devices, according to their capabilities. The main value of JXME is its simplicity to create peer-to-peer (P2P) applications in limited devices. In addition to assessing JXME functionalities, it is also important to realize the default security level provided. This paper presents a brief analysis of the current state of security in JXME, focusing on the JXME-Proxied version, identifies existing vulnerabilities and proposes further improvements in this field.

Associations between online pornography and sexual behavior among adolescents: myth or reality?

This study aimed to compare the sexual behavior of adolescents who were or were not exposed to online pornography, to assess to what extent the willingness of exposure changed these possible associations, and to determine the profiles of youths who were exposed to online pornography. Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health, a self-administered cross-sectional, paper and pencil questionnaire. From the 7529 adolescents aged 16-20 years, 6054 (3283 males) used the Internet during the previous month and were eligible for our study. Males were divided into three groups (wanted exposure, 29.2%; unwanted exposure, 46.7%; no exposure, 24.1%) whereas females were divided into two groups (exposure, 35.9%; no exposure, 64.1%). The principal outcome measures were demographic characteristics, Internet use parameters and risky sexual behaviors. Risky sexual behaviors were not associated with online pornography exposure in any of the groups, except that males who were exposed (deliberately or not) had higher odds of not having used a condom at last intercourse. Bi/homosexual orientation and Internet use parameters were not associated either. Additionally, males in the wanted exposure group were more likely to be sensation-seekers. On the other hand, exposed girls were more likely to be students, higher sensation-seekers, early maturers, and to have a highly educated father. We conclude that pornography exposure is not associated with risky sexual behaviors and that the willingness of exposure does not seem to have an impact on risky sexual behaviors among adolescents.

De què vas, tio?

My study is based on an ethnography of two groups of young people from working-class neighbourhoods in Barcelona. I was interested in researching the impact of Catalan language policies on the identities of young people of Spanish-speaking immigrant families. I sought to go beyond the constraints of traditional structuralist approaches in Sociolinguistics in order to make my analysis relevant to people working for gender equality, the promotion of the Catalan language, or other social causes. I combine ideas from Bakhtin, Bourdieu, Fairclough, Foucault and Goffman to build a dialectical, historical, process-centred perspective that conceptualises practices in terms of social and political struggles.I analyse young people's peer-group activities in terms of their significance for the construction of gender identities. I propose a variety of forms of masculinity and femininity according to the various ways in which members organised their gender displays in face-to-face interaction.I also show how their use of argot and dialectal Spanish was part of the processes whereby members defined their relationships, constructed particular subject positions in interaction and struggled to legitimate their own values.I explore the meanings constructed through Catalan and Spanish by looking into the code-switching practices of my participants. I analysed their talk in terms of narratives that present particular sequential dramatisations of events for conversational audiences. These narratives follow the expressive intention of the author, and are populated with multiple voices of animated characters. I argue that, in the groups I studied, Catalan was generally not used to animate the voices that were central to the identities of the peer-group, and particularly to masculine identities.In order to contextualise these practices within the wider society, I also look into the processes of language choice in face-to-face encounters. I argue that existing conventions made it difficult for people to find opportunities to speak Catalan. I also pointed to the difficulties that my participants had to find employment, which were particularly acute amongst the more politically aware individuals. I conclude that these young working-class people had little possibilities of investing in more egalitarian forms of identity given their lack of resources and opportunities to develop their identities in other social spaces, such as the workplace.

Cannabis use and other predictors of the onset of daily cigarette use in young men: what matters most? Results from a longitudinal study.

BACKGROUND: According to the gateway hypothesis, tobacco use is a gateway of cannabis use. However, there is increasing evidence that cannabis use also predicts the progression of tobacco use (reverse gateway hypothesis). Unfortunately, the importance of cannabis use compared to other predictors of tobacco use is less clear. The aim of this study was to examine which variables, in addition to cannabis use, best predict the onset of daily cigarette smoking in young men. METHODS: A total of 5,590 young Swiss men (mean age = 19.4 years, SD = 1.2) provided data on their substance use, socio-demographic background, religion, health, social context, and personality at baseline and after 18 months. We modelled the predictors of progression to daily cigarette smoking using logistic regression analyses (n = 4,230). RESULTS: In the multivariate overall model, use of cannabis remained among the strongest predictors for the onset of daily cigarette use. Daily cigarette use was also predicted by a lifetime use of at least 50 cigarettes, occasional cigarette use, educational level, religious affiliation, parental situation, peers with psychiatric problems, and sociability. CONCLUSIONS: Our results highlight the relevance of cannabis use compared to other potential predictors of the progression of tobacco use and thereby support the reverse gateway hypothesis.

Naisyrittäjien välinen vertaistuki, Case: Yrittäjyyden Tuki-projekti

Yrittäjyyden Tuki - projekti toimi osana valtakunnallista WomEqual - kehittämiskumppanuushanketta vuosina 2005-2007 tavoitteenaan tukea naisyrittäjien toimintaedellytyksiä kehittäen heille vertaisryhmätoimintaan perustuvaa tukimallia. Tässä tutkimuksessa ensisijaisena tavoitteena on selvittää, miten kyseisen projektin vertaisryhmätoimintaan osallistuneet naisyrittäjät kokivat naisyrittäjien välisen vertaistuen toimintamuotona. Pyrkimyksenä on myös ymmärtää, mitkä seikat sitouttivat naisyrittäjiä vertaisryhmätoimintaan ja mitä he kokivat oppineensa vertaisryhmätoiminnan seurauksena. Lisäksi kiinnostuksen kohteena on tarkastella, kuinka vertaistukiryhmä toimii naisyrittäjien välisen verkostoitumisen välineenä. Tutkimus on laadullinen ja aineistolähtöinen. Tutkimuksen primääriaineisto on kerätty puolistrukturoiduin teemahaastatteluilla ja sekundaariaineisto kyselytutkimuksen avulla. Tutkimustulokset osoittavat, että naisyrittäjät kokevat henkisen ja sosiaalisen tuen tärkeäksi. Toiselta naisyrittäjältä, vertaiselta, saatu tuki koettiin vertaistukiryhmän vahvuudeksi. Vertaisryhmässä oppiminen tapahtui kokemusten jakamisen kautta. Uusien verkostojen luomisessa vertaistukiryhmä ei täysin vastannut odotuksia.

jxSensor: a sensor network integration layer for JXTA

Nowadays, Wireless Sensor Networks (WSN) arealready a very important data source to obtain data about the environment. Thus, they are key to the creation of Cyber-Physical Systems (CPS). Given the popularity of P2P middlewares as ameans to efficiently process information and distribute services, being able to integrate them to WSN¿s is an interesting proposal. JXTA is a widely used P2P middleware that allows peers to easily exchange information, heavily relying on its main architectural highlight, the capability to organize peers with common interests into peer groups. However, right now, approaches to integrate WSNs to a JXTA network seldom take advantage of peer groups. For this reason, in this paper we present jxSensor, an integrationlayer for sensor motes which facilitates the deployment of CPS¿s under this architecture. This integration has been done taking into account JXTA¿s idiosyncrasies and proposing novel ideas,such as the Virtual Peer, a group of sensors that acts as a single entity within the peer group context.

Lentopetrolin hinnanmuutoksilta suojautuminen johdannaisilla Case Jetflite Oy

Tutkielman tavoitteena on selvittää, miten lentoyhtiöt, kuten case-yritys Jetflite Oy, voivat hyödyntää johdannaisinstrumentteja suojautuessaan polttoainekustannusten nousulta. Tutkielmassa kootaan tietoa eri lentoyhtiöiden riskienhallintastrategioista ja niiden implementoinnissa käytetyistä johdannaissopimustyypeistä. Tutkielmassa pyritään tuottamaan tietoa case-yrityksen johdolle riskienhallintastrategian luomista varten kartoittamalla toteutuneita polttoainekustannuksia Jetfliten ostolaskuista. Lentoyhtiöt voivat määritellä suojausstrategian, jonka mukaisesti määrättynä ajanjaksona haluttu osuus tulevista polttoainehankinnoista suojataan johdannaissopimuksin muun muassa futuureita, optioita ja swappeja käyttäen. Johdannaisia käytetään sekä lähitulevaisuuden polttoainehankintojen suojauksissa että pitkän aikavälin riskienhallintastrategioita toteutettaessa. Koska polttoainekustannukset ovat lentoyhtiöiden toiminnan kannattavuuden kannalta keskeinen kuluerä, on em. kustannusten nousulta suojautuminen lentoyhtiöille myös strateginen menestystekijä.

Induction practices : experiences of newly qualified teachers

The thesis consists of four studies (articles I–IV) and a comprehensive summary. The aim is to deepen understanding and knowledge of newly qualified teachers’ experiences of their induction practices. The research interest thus reflects the ambition to strengthen the research-based platform for support measures. The aim can be specified in the following four sub-areas: to scrutinise NQTs’ experiences of the profession in the transition from education to work (study I), to describe and analyse NQTs’ experiences of their first encounters with school and classroom (study II), to explore NQTs’ experiences of their relationships within the school community (study III), to view NQTs’ experiences of support through peer-group mentoring as part of the wider aim of collaboration and assessment (study IV). The overall theoretical perspective constitutes teachers’ professional development. Induction forms an essential part of this continuum and can primarily be seen as a socialisation process into the profession and the social working environment of schools, as a unique phase of teachers’ development contributing to certain experiences, and as a formal programme designed to support new teachers. These lines of research are initiated in the separate studies (I–IV) and deepened in the theoretical part of the comprehensive summary. In order to appropriately understand induction as a specific practice the lines of research are in the end united and discussed with help of practice theory. More precisely the theory of practice architectures, including semantic space, physical space-time and social space, are used. The methodological approach to integrating the four studies is above all represented by abduction and meta-synthesis. Data has been collected through a questionnaire survey, with mainly open-ended questions, and altogether ten focus group meetings with newly qualified primary school teachers in 2007–2008. The teachers (n=88 in questionnaire, n=17 in focus groups), had between one and three years of teaching experience. Qualitative content analysis and narrative analysis were used when analysing the data. What is then the collected picture of induction or the first years in the profession if scrutinising the results presented in the articles? Four dimensions seem especially to permeate the studies and emerge when they are put together. The first dimension, the relational ˗ emotional, captures the social nature of induction and teacher’s work and the emotional character intimately intertwined. The second dimension, the tensional ˗ mutable, illustrates the intense pace of induction, together with the diffuse and unclear character of a teacher’s job. The third dimension, the instructive ˗ developmental, depicts induction as a unique and intensive phase of learning, maturity and professional development. Finally, the fourth dimension, the reciprocal ˗ professional, stresses the importance of reciprocity and collaboration in induction, both formally and informally. The outlined four dimensions, or integration of results, describing induction from the experiences of new teachers, constitute part of a new synthesis, induction practice. This synthesis was generated from viewing the integrated results through the theoretical lens of practice architecture and the three spaces, semantic space, physical space-time and social space. In this way, a more comprehensive, refined and partially new architecture of teachers’ induction practices are presented and discussed.

Same- and Other-Sex Victimization : Risk Factors, Consequences, and Protection by Peers

Bullying can be viewed as goal-oriented behavior in the strive for dominance and prestige in the peer group (Salmivalli, 2010). To ensure the effectiveness of their power demonstrations, bullies often choose targets from among their vulnerable peers (Salmivalli, 2010; Veenstra et al., 2007). A large number of studies have also shown that victimization has severe consequences for the victims’ psychosocial adjustment (Reijntjes, Kamphuis, Prinzie, & Telch, 2010; Ttofi, Farrington, Lösel, & Loeber, 2011). In this thesis I investigate – based on three empirical studies – whether similar dynamics on the risk factors and consequences apply to same- and other-sex victimization. In the empirical studies, we used the data from the randomized control trial of the KiVa antibullying program for the elementary school grades 4–6 (2007–2008), and for the middle school grades 7–9 (2008–2009). We measured same- and other-sex victimization, and victims’ defending relationships by dyadic questions: “By which classmates are you victimized?” and “By which classmates are you supported, comforted, or defended?” In addition, we used self-reports and peer reports to measure adjustment and social status. The findings imply that other-sex victimization may be challenging for antibullying work. First, although targets of bullying seemed to be selected from among vulnerable peers for the most part, perceived popularity increased the risks of other-sex victimization. Popularity of these victims may falsely lead to an impression that the victims are doing well. Second, the consequences considering victims’ later psychosocial adjustment were alarming concerning girls bullied by boys. Thus, despite the fact that the targets may be perceived as popular, other-sex victimization can have even more severe consequences than same-sex victimization. Third, we found that defending relationships were mostly same-sex relationships, and consequently, we may ask whether defending is effective against other-sex bullies. Finally, the KiVa antibullying program was less effective against other-sex victimization in the adolescent sample. The findings altogether emphasize the importance of taking into account the sex composition of the bully-victim dyad, both considering future research on bullying and in the antibullying work with children and adolescents.

Bullying as a social process : factors influencing bystander behaviour

Bullying was approached as a social phenomenon in the present study. The central aim of this thesis was to uncover some of the factors that contribute to the attitudes and behavioural choices of bystanders during bullying situations. With this type of information, interventions can be tailored to change the behaviour of bystanders during bullying situations, and thus the ethos of the larger group. Thus, acting to alter the available sources of reinforcement for bullying behaviour and peer intervention attempts. Six hundred and twenty-six students participated. Students were sampled from grades 4 (n=140), 5 (n=l 13), 7 (n=205), and 8 (n=168). Students were measured for their involvement in bullying and victimization, as well as for involvement in the following bystander behaviours: encouraging, onlooking, defending, and seeking adult support. In addition, students were measured for tolerance of deviance, pro-victim attitudes, social anxiety and fear, and self-efficacy for peer intervention. Last, students were asked to complete a series of qualitative measures, including a series of hypothetical vignettes and open-ended questions. Analyses centered on the following areas: 1) rates of bullying, victimization, and bystander behaviour; 2) the influence of age and gender on bystander behaviour; 3) the characteristics associated with students who predominantly report involvement with defending, seeking adult assistance, encouraging, and onlooking behaviour; and 4) the influence of past involvement with bullying and victimization on bystander behaviour. b .--' -i . k Rates of bullying, victimization, and bystander behaviour were comparable to findings in the existing literature, where male students were more likely than female students to report involvement in both bullying and victimization. Boys were more likely than girls to report participation in encouraging and onlooking behaviours, while being less likely to report involvement in defending and seeking adult assistance. Partly consistent with existing findings, older students were more likely to report involvement in bullying, encouraging, and onlooking behaviour than younger students, who were more likely to report victimization, defending, and seeking adult assistance. Self-identified encouragers and onlookers reported a similar array of characteristics, in that they tended express high levels of tolerance of deviance, while expressing low levels of pro-victim attitudes and self-efficacy for peer intervention. Likewise, self-identified defenders and seekers of adult assistance tended to report a similar array of characteristics to each other, in that they tended to report low levels of tolerance of deviance, while expressing high levels of pro-victim attitudes and self efficacy for peer intervention. Additionally, self-identified bullies and self-identified bully-victims tended to report increased involvement in encouraging and onlooking, whereas self-identified victims tended to report increased involvement in defending behaviour and seeking adult assistance. Results are discussed in terms of implications for bullying prevention and intervention. Specifically, evidence from the present study suggests that as bystanders, students predominantly act to either support bullying acts or to support the victims of these acts, or alternatively, to actively remain outside bullying situations. Thus, encouraging students to make small changes in the way they express these sentiments during bullying situations would act to alter the culture of the larger peer group and the sources of reinforcement available for bullying acts as well as peer intervention attempts.

Business leadership in the classroom

This action research assesses a framework that assists business educators in promoting leadership within a classroom. It is designed to better prepare students to assume leadership and fill the "leadership gap" in business. Two classes of 2nd-year community college business students participated in running and managing their own business community as teams of sales professionals by developing and practicing their own individual leadership for 28 weeks during their sales courses. The intent was to assess the development of leadership resulting from the implementation of the "Business Leadership in the Classroom" framework. This framework balances leadership principles to simulate a business environment with the practical elements of a learning community under the facilitation of an experienced business educator. The action research approach was used to assess and adjust approaches to business leadership on a continuous basis throughout the research. Data were collected from 61 students based on journals, surveys, peer group reviews, and my (facilitator) reflective journal.The findings reveal that both individual and collective business leadership views and practical skills developed over time. A business leadership mind-set evolved that ranged from a general awareness of the importance of leadership, to a conscious and deliberate use of individual leadership. Areas important in building a progression of leadership included: leadership teams, membership roles, weekly leadership teams, peer feedback, and activity-based learning. Emerging themes included leadership, leadership style, teamwork, as well as influence and motivation. The research framework was effective in supporting the development of business leadership but required some adjustments. These included increased structure and feedback mechanisms. Interpretation of the findings demonstrates the importance of real-world practical education in the classroom. Results show how focusing on a single mind-set such as business leadership, can result in enormous individual growth and development. When business students are encouraged to act as real businesspeople, managing their own learning, the results are effective in preparing them for the business world. All participants expressed their leadership in different ways based on personality and individual strengths. There was an overwhelming and, in some cases, passionate interest in leadership. The use of action research with a range of data collection methods provides a way to measure and track individual student learning and to generate adjustments to the research framework design and learning approaches. The findings generate implications and recommendations to continue this research further. Key recommendations center around how to ensure leadership development is sustained, including improved approaches to heighten the real-world feel of the classroom. Specifically, the use of leadership goals and action plans for each individual participant and an active use of outside business resource people as contacts for participants is recommended.

Les caractéristiques des amis comme facteurs de risque et de protection associés à la victimisation par les pairs à l’adolescence: une perspective longitudinale

Cette étude s’intéresse aux relations d’amitié et aux caractéristiques des amis comme facteurs de risque interpersonnels susceptibles de prédire les changements à travers le temps, de la victimisation par les pairs au début du secondaire. L’échantillon est composé de 524 élèves de secondaire I et II pour lesquels le niveau de victimisation a été mesuré par les pairs lors de deux années consécutives. Les facteurs de risque individuel associés à la victimisation par les pairs (i.e. les comportements agressifs, les comportements de retrait social et le rejet par les pairs) ainsi que les caractéristiques des amis (i.e. agressivité, retrait social et victimisation des amis) ont également été évalués par les pairs lors du premier temps de mesure. Les résultats démontrent qu’au-delà des facteurs de risque individuels, un plus grand nombre d’amis prédit une diminution de la victimisation par les pairs sur une période d’un an. De plus, pour les élèves rejetés socialement, la victimisation des amis permet de rendre compte d’une augmentation de la victimisation dans le temps. Contrairement aux résultats obtenus par d’autres études, l’agressivité des amis permet de prédire une diminution de la victimisation seulement pour les élèves bien acceptés socialement. Pour les jeunes qui sont rejetés socialement, l’agressivité des amis permet de prédire une augmentation de la victimisation par les pairs. Ces résultats apportent un regard nouveau sur l’inter influence entre l’identité des amis et le contexte social dans lequel les adolescents évoluent.
