Teleoperaattorinlaajakaistaviankorjauksen tehostaminen

Työssä tutkittiin voidaanko helpdesk-asiantuntijoille kehitetyn asiantuntijan ja tietojärjestelmän väliseen dialogiin ja puumaiseen ongelmanratkaisulogiikkaan perustuvan tukijärjestelmän käytöllä tehostaa laajakaistaliittymäviankorjausta. Työ selvitti dialogi-työkalun käyttöönoton jälkeisen vuoden seurantajakson aikana helpdeskin ongelmanratkaisuasteen ja liittymäviankorjausprosessin kehitystä sekä arvioi prosessin tehostumisen vaikutusta palvelun laatuun. Seurantajakson aikana helpdeskissä päätettyjen asiakaskontaktien määrä kasvoi merkittävästi, viankorjausprosessin keskimääräinenläpimenoaika lyhentyi ja vikailmoituksen kohdentamistarkkuus oikeaan työjonoon parani. Prosessin tehostumista kuvaavien mittareiden muutos on tilastollisesti erittäin merkitsevä. Dialogi-työkalulla voidaan tehostaa laajakaistaliittymien viankorjausprosessia merkittävästi ja vaikuttaa joiltain osin myös palvelun laatuun.

Dialogue journal writing: a tool for critical reflection in the adult ESL learner

This study attempted to determine whether or not dialogue journal writing encouraged critical reflection in the adult ESL (English as a Second Language) learner. According to research in adult education and anecdotal evidence, the process ofdialogue journal writing can facilitate critical reflection in the adult learner. However, little research has been conducted to examine whether or not journal writing can facilitate critical reflection in the second language learner. As a result, ten low-intermediate level adult ESL students from Brock University's Intensive English Language Programme participated in a dialogue journal writing programme in their writing class. The participants wrote journal entries over a 10-week period, and were interviewed once throughout the process to determine their perceptions ofthe journal writing experience. They also were observed by the researcher throughout the journal writing sessions to establish whether any behaviours or intrusions might affect the participants' writing processes. After the content ofthe journals and the interviews, and the observations made by the researcher were analysed, it was confirmed that, for these participants, dialogue journal writing did not necessarily encourage critical reflection. Moreover, the participants' perceptions ofjournal writing were that it helped them to practise the syntax, vocabulary, and rhetorical patterns ofEnglish; nevertheless, it did not foster critical reflection or thinking.

Corporate responsibility guaranteed by dialogue? Examining the relationship between nongovernmental organizations and business

The main objective of this doctoral dissertation is to examine the relationship between non-governmental organizations and business in the context of academic discourse, corporate responsibility discourse, and stakeholder dialogue. More specifically, motivated by the increasing emphasis on stakeholder dialogue as a tool for corporate responsibility and accountability, the aim is to critically assess the role of stakeholder dialogue as a self-regulatory mechanism, in particular from the perspective of foreign direct investments. The study comprises two parts; an introductory essay containing the research objectives, theoretical foundations and methodological choices, and four research articles that address one sub-objective: 1) to review the literature on NGO-business relations in business and society, management, and international business journals from 1998–2007; 2) to critically analyze the academic discourse on NGO-business relations; 3) to analyze the problematic aspects of sustainable foreign direct investments as a conceptual construct; and 4) to analyze the problematic aspects of stakeholder dialogue in connection with a foreign direct investment. The ontological and epistemological foundations of this dissertation build on the social constructionist view of reality. The dialogue in this study is viewed as a legitimacy bargaining process that is actively shaped by societal parties in discourse. Similarly, articulations of ‘partnership’ and ‘adversarial’ in NGO-business relations in academic business and society discourse are viewed as competing hegemonic interventions in the field. More specifically, the methods applied in the articles are literature review (Article 1), discourse theory (Article 2), conceptual analysis (Article 3), and case study with document analysis (Article 4). This dissertation has three main arguments and contributions. First, it is argued that the potential of stakeholder dialogue as a tool for corporate responsibility and accountability is inherently limited in both contexts. Second, the study shows the power implications of privileging partnership oriented NGO-business relations over adversarial ones, and of placing business at the centre of governance discourse. The third contribution is methodological: a new way to analyze academic discourse is presented by focusing on the problem setting of an article.

Les postures des animateurs et des animatrices scientifiques quant au dialogue "sciences en/et société"

Cette recherche a eu pour objectif d’explorer les postures d’animateurs et d’animatrices scientifiques quant au dialogue « sciences en/et société » et les moyens qu’ils utilisent pour assurer ce dialogue à travers leurs interventions pédagogiques dans le cadre d’ateliers scientifiques hors scolaires. Six animateurs scientifiques ont été interviewés. Ces entretiens ont permis de recueillir des données riches sur leur compréhension de la nature des sciences, leurs postures pédagogiques en tant que transmetteur, guide ou médiateur du développement de l’alphabétisation scientifique chez les jeunes dans les espaces hors scolaires, ainsi que sur la manière dont ils perçoivent le rôle de leurs interventions pédagogiques dans le cadre du développement de l’alphabétisation scientifique chez les jeunes et de la compréhension qu’ils ont des sciences comme outil d’action sociopolitique, tel qu’entendu dans le dialogue « sciences en/et société ». Les postures épistémologiques, pédagogiques et sociales identifiées sont d’une grande diversité et révèlent des tendances qui s’inscrivent dans des spectres allant de l’empirisme au constructivisme, du divertissement à l’empowerment et de la valorisation de la place des sciences en société à la critique de sa primauté. Plusieurs animateurs scientifiques de notre échantillon ont ainsi eu des postures hybrides et parfois conflictuelles, ce qui met en évidence la valeur potentielle d’interventions éducatives qui donnent aux animateurs scientifiques l’occasion de questionner et de réexaminer de manière critique leurs pratiques.

A tool for mapping research skills in undergraduate curricula

There has been considerable interest recently in the teaching of skills to undergraduate students. However, existing methods for collating data on how much, where and when students are taught and assessed skills have often been shown to be time-consuming and ineffective. Here, we outline an electronic research skills audit tool that has been developed to map both transferable and discipline-specific skills teaching and assessment within individual modules, the results of which can be collated and analysed across entire degree programmes. The design and use of the audit tool is described in detail and a bioscience case study is presented to illustrate the types of data that can be collected. The audit tool has been designed as a time-effective way of collecting information on skills teaching and assessment, but also actively encourages staff to reflect on their teaching and learning practices. Conclusions are drawn about the practicalities of using the audit tool and its importance in both curriculum design and as a resource to encourage dialogue with graduate employers.

Exploratory study of corporate social responsibility: blogs as a communication tool to enhance company-stakeholders relationships

O conceito de responsabilidade social corporativa (RSE) evoluiu gradualmente do objetivo de satisfazer as expectativas dos acionistas para o cumprimento das expectativas das partes interessadas. Tornou-se um conceito amplamente aceitado e promovido como as empresas enfrentam maiores pressões de atores internos e externos para cumprir objetivos sociais maiores. Assim, elas cada vez mais comunicam sobre os esforços de responsabilidade social delas, a fim de fomentar a confiança e o envolvimento dos stakeholders. Mas o aumento da cidadania global e as novas tecnologias de informação e de comunicação – como as mídias sociaias – está criando uma paisagem desafiador para a comunicação RSE, se traduzindo em escrutínio e ceticismo do público. No entanto, também está criando novas oportunidades para as empresas compartilhar e interagir com as partes interessadas. O estudo analisa especificamente como os blogs corporativos dedicados à comunicação RSE conseguem melhorar as relações entre as empresas e as partes interessadas. Esta pesquisa exploratória da estrutura e das mensagens de 9 blogs corporativos, é baseada em um quadro de análise sobre comunicação RSE em plataformas de mídias sociais desenvolvido por Gomez e Chalmeta (2013). O quadro está melhorado e adaptado para blogs graças à literatura sobre comunicação RSE, mídias sociais e blogs corporativos. Os resultados demonstram que o uso de características de blogs como apresentação, conteúdo e interatividade, é diversificado e reflete estratégias diferentes de comunicação RSE. Blogs permitem às empresas aumentar a visibilidade da comunicação RSE, melhorar a credibilidade e a legitimidade dos esforços de responsabilidade social, e também trazer discussões com os stakeholders. No entanto, demonstramos que as características e recursos dos blogs raramente são totalmente desenvolvidos, sugerindo avenidas para a melhoria no campo da comunicação nas mídias sociais. Especificamente, o uso da interatividade para criar relações baseadas em diálogo entre empresas e stakeholders está até atrasado em relação à extensão das oportunidades oferecidas pelos blogs. Além disso, o grau de utilização das ferramentas de blogs determina a eficácia da comunicação de RSE 2.0 das empresas na criação de relações empresa-stakeholder.

Intercultural Performance and Dialogue. From Richard Schechner Performance Studies Onwards

Attraverso un excursus storico, teorico e metodologico, questa tesi di dottorato analizza la nascita, gli sviluppi e l’attuale dimensione costitutivo-identitaria dei Performance Studies, un ambito di ricerca accademica che, nato negli Stati Uniti alla fine degli anni Settanta, ha sempre palesato una natura restia nei confronti di qualunque tentativo definitorio. Se i Performance Studies concepiscono la performance sia come oggetto d’analisi sia come lente metodologica, e se, come evidenziato da Richard Schechner, praticamente tutto può essere “elevato a performance” e quindi indagato secondo le categorie analitiche di questa disciplina, ecco allora che, con uno slittamento transitivo e “meta-metodologico”, questa ricerca dottorale ha scelto come proprio oggetto di studio i Performance Studies stessi, osservandoli “as performance” e avvalendosi degli strumenti metodologici suggeriti dal suo stesso oggetto d’analisi. Questo lavoro indaga come l’oggetto di studio dei Performance Studies sia, seguendo la teoria schechneriana, il “behaved behavior”, e dunque come di conseguenza, il repertorio, prima ancora che l’archivio, possa essere considerato il fedele custode delle “pratiche incorporate”. Soffermandosi su esempi di “reenactment” performativo come quelli messi in atto da Marina Abramović e Clifford Owens, così come sui tentativi condotti dalla sezione dell’Intangible Cultural Heritage dell’UNESCO, suggerisce validi esempi di “archiviazione” della performance. L’elaborato prende poi in esame casi che esemplificano la proficua identificazione tra “studiare performance” e “fare performance”, sottolinea il ruolo cruciale e imprenscindibile determinato dal lavoro di ricerca sul campo inteso come “osservazione partecipante”, ed evidenzia il costante coinvolgimento sociale e politico assunto dai Performance Studies. Questa dissertazione affronta e supporta l’efficacia dei Performance Studies nel proporsi come uno strumento innovativo in grado di analizzare un mondo sempre più performativo nelle sue dinamiche. La loro natura tanto interdisciplinare quanto interculturale sembra farne una lente adeguata attraverso cui promuovere livelli diversi di performance dialogica tra culture localmente distinte ma globalmente assimilabili.

Partnership Actions for Mitigating Syndromes (PAMS): Experience with a transdisciplinary tool in the NCCR North-South programme

Partnership Actions for Mitigating Syndromes (PAMS) are small transdisciplinary projects which bring scientific research insights from the NCCR North-South into policy and practice. They are implemented by researchers from different disciplines in collaboration with non-scientific actors. PAMS aim to implement and test approaches, methods and tools developed in research, in order to identify promising strategies and potentials for sustainable development. In this sense, they are solution-oriented. This paper will provide insights into our experience with PAMS, with a special focus on the implementation of transdisciplinarity and its outcomes. From 2001 to 2010, 77 PAMS were implemented in Africa, Asia and Latin America. An internal evaluation of the first 55 projects was conducted in 2006. Results of this evaluation led to a refinement and improvement of the tool. A second internal evaluation is currently underway in the NCCR North-South. This evaluation will provide an overview of 22 new PAMS. We will look at partners involved, project beneficiaries, activities implemented, outcomes achieved, and lessons learnt. In the first evaluation, transdisciplinarity was considered as “a form of collaboration within scientific fields … and as a form of continuous dialogue between research and society” (Messerli et al., 2007). The evaluation report concluded that this understanding of transdisciplinarity was not satisfactorily applied in the 55 projects. Only about half of the PAMS addressed mutual exchange between researchers and society. Some involved only one specific field of research and clearly lacked interdisciplinary co-operation, and most often knowledge was transferred mainly unilaterally from the scientific community to society, without society having any effect on science. It was therefore recommended to address transdisciplinarity more carefully in Phase 2 PAMS. The second evaluation, which is currently under way, is analysing whether and how this recommendation has been met, based on criteria defined in the NCCR North-South’s Outcome Monitoring Strategy. The analysis is focusing on partners with whom researchers interact and investigating whether practices have changed both in research and society. We are also exploring the role of researchers in PAMS. Preliminary results show that researchers can assume different roles, from direct implementation, mediation, and promotion of social learning between different actors, to giving advice as neutral outsiders.

Sim-xl: A Powerful And User-friendly Tool For Peptide Cross-linking Analysis.

Chemical cross-linking has emerged as a powerful approach for the structural characterization of proteins and protein complexes. However, the correct identification of covalently linked (cross-linked or XL) peptides analyzed by tandem mass spectrometry is still an open challenge. Here we present SIM-XL, a software tool that can analyze data generated through commonly used cross-linkers (e.g., BS3/DSS). Our software introduces a new paradigm for search-space reduction, which ultimately accounts for its increase in speed and sensitivity. Moreover, our search engine is the first to capitalize on reporter ions for selecting tandem mass spectra derived from cross-linked peptides. It also makes available a 2D interaction map and a spectrum-annotation tool unmatched by any of its kind. We show SIM-XL to be more sensitive and faster than a competing tool when analyzing a data set obtained from the human HSP90. The software is freely available for academic use at http://patternlabforproteomics.org/sim-xl. A video demonstrating the tool is available at http://patternlabforproteomics.org/sim-xl/video. SIM-XL is the first tool to support XL data in the mzIdentML format; all data are thus available from the ProteomeXchange consortium (identifier PXD001677).

Capillary electrophoresis (CE): a powerful tool to characterize humic acid (HA)

The present study evaluates the possibility of eliminating the purification steps involved in the characterization of HA by capillary zone electrophoresis (CZE). The HAs of various sources were analyzed, showing different electropherograms by CZE, which depend on the charge and size of HA. The data suggest that the purification of the sample is not necessary to characterize HAs. Based on the results, CZE showed to be a promising tool to characterize HA of different origins without the purification step of the sample.

Catalytic enantioselective arylations: boron to zinc exchange as a powerful tool for the generation of transferable aryl groups

The transmetalation between boron and zinc is of great importance for application in organic synthesis, since it allows the formation of new carbon-carbon bonds between organometallic units and electrophiles. The direct arylation of aldehydes or more scarcely ketones, in a catalytic, enantioselective manner using chiral catalysts has been described recently. The enantiomerically enriched diarylmethanols obtained in these reactions are valuable precursors for important bioactive molecules. This review provides a synopsis of this ever-growing field and highlights some of the challenges that still remain.

Ratio of weight to height gain: a useful tool for identifying children at risk of becoming overweight or obese at preschool age

PURPOSE: To analyze the usefulness of the weight gain/height gain ratio from birth to two and three years of age as a predictive risk indicator of excess weight at preschool age. METHODS: The weight and height/length of 409 preschool children at daycare centers were measured according to internationally recommended rules. The weight values and body mass indices of the children were transformed into a z-score per the standard method described by the World Health Organization. The Pearson correlation coefficients (rP) and the linear regressions between the anthropometric parameters and the body mass index z-scores of preschool children were statistically analyzed (alpha = 0.05). RESULTS: The mean age of the study population was 3.2 years (± 0.3 years). The prevalence of excess weight was 28.8%, and the prevalence of overweight and obesity was 8.8%. The correlation coefficients between the body mass index z-scores of the preschool children and the birth weights or body mass indices at birth were low (0.09 and 0.10, respectively). There was a high correlation coefficient (rP = 0.79) between the mean monthly gain of weight and the body mass index z-score of preschool children. A higher coefficient (rP = 0.93) was observed between the ratio of the mean weight gain per height gain (g/cm) and the preschool children body mass index z-score. The coefficients and their differences were statistically significant. CONCLUSION: Regardless of weight or length at birth, the mean ratio between the weight gain per g/cm of height growth from birth presented a strong correlation with the body mass index of preschool children. These results suggest that this ratio may be a good indicator of the risk of excess weight and obesity in preschool-aged children.

Flow cytometry as a tool in the evaluation of blood leukocyte function in Chelonia mydas (Linnaeus, 1758) (Testudines, Cheloniidae)

Chelonia mydas is a sea turtle that feeds and nests on the Brazilian coast and a disease called fibropapillomatosis is a threat to this species. Because of this, it is extremely necessary to determine a methodology that would enable the analysis of blood leukocyte function in these sea turtles. In order to achieve this aim, blood samples were collected from C. mydas with or without fibropapillomas captured on the São Paulo north coast. Blood samples were placed in tubes containing sodium heparin and were transported under refrigeration to the laboratory in sterile RPMI 1640 cell culture medium. Leukocytes were separated by density gradient using Ficoll-PaqueTM Plus, Amershan Biociences®. The following stimuli were applied in the assessment of leukocyte function: Phorbol Miristate-Acetate (PMA) for oxidative burst activity evaluation and Zymosan A (Saccharomyces cerevisiae) Bio Particles®, Alexa Fluor® 594 conjugate for phagocytosis evaluation. Three cell populations were identified: heterophils, monocytes and lymphocytes. Monocytes were the cells responsible for phagocytosis and oxidative burst.
