Previous issue date: 2013-09-18 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / This study focuses on researching the possibilities and limits of student authorship
promoted through the use of digital Communication and Information Technologies
(CIT) and of digital media. The investigation also analyzes the role of these tools in
contributing for the development of student authorship in the educational process at
one selected school. The purpose of this study resides in the relevance of the theme
today since communication, production, use and sharing of information are
increasingly more present in social and virtual relationships. Furthermore, there are
few studies about the topic, and even fewer which analyze student authorship
through the use of digital media and CIT. The context of study is a private school in
the city of Sao Paulo, which has been developing practices with digital CIT for over
10 years. One of such practices is the workshop about production of multimedia
news content, which is offered from 7th graders to the senior year of high school.
This is a qualitative study that used focus group protocol involving eight students and
the teaching team, which included the teacher, the school principal and two
journalists, besides the application of a questionnaire with the students and a
documental analysis based on the workshop planning and the students blog. Results
showed that students exert their authorship with responsibility and awareness, with
the help of teachers mediation. During the process of creation and content
production, students exert their authorship both individually and collectively, which
allows for collaboration and interaction among them. They frequently resort to digital
media and CIT to express their ideas through a number of different languages, and
for the creation of news stories - which requires the development of creativity,
autonomy and a critical view from their participants. Hence, students are no longer
consumers: they start to be the producers of information which is shared in the
knowledge network of the digital culture. It also shows that exercising authorship is
the type of practice that contributes to build knowledge with the students in an active
and engaged manner and presents viewpoints that enhance the integration of digital
media and CIT in the educational process / O presente estudo tem por objetivo investigar as possibilidades e os limites da
autoria de alunos com o uso das Tecnologias Digitais de Informação e Comunicação
(TDIC) e das mídias digitais e analisar como estas podem contribuir para o
desenvolvimento da autoria pelos alunos no processo educativo da escola
investigada. Apresenta, como justificativa, a importância do tema na realidade atual,
em que a comunicação, a produção, o uso e o compartilhamento de informações
estão cada vez mais presentes nas relações sociais e virtuais. Além do mais, são
poucas as produções acadêmicas sobre o tema, principalmente quando se referem
à autoria dos alunos com o uso das TDIC e das mídias digitais. O contexto da
investigação é uma escola privada da cidade de São Paulo, que, há mais de 10
anos, desenvolve práticas com o uso das TDIC, entre as quais a Oficina de
produção de conteúdo multimídia com caráter jornalístico, oferecida aos alunos que
cursam da 7º série do Ensino Fundamental II até o 3º ano do Ensino Médio. O
estudo de cunho qualitativo utilizou a técnica de grupo focal com oito alunos e com a
equipe docente, composta pela professora, coordenadora e dois jornalistas, além da
aplicação de um questionário para os alunos e uma análise documental, composta
pelos roteiros da Oficina e o blog produzido pelos alunos. A pesquisa apresentou
como resultados, que os alunos exercem sua autoria de forma consciente e
responsável, sob mediação dos professores. Durante o processo de criação e
produção dos conteúdos, os alunos exercem a autoria de forma individual e coletiva,
o que permite a colaboração e a interação entre os alunos. Utilizam com frequência
as TDIC e as mídias digitais para expressarem suas ideias por meio das diferentes
linguagens e para criação das matérias jornalísticas produzidas, que exigem o
desenvolvimento da criatividade, da autonomia e de um olhar crítico de seus
participantes. Desta forma, os alunos deixam de ser consumidores e passam a ser
produtores de informação, que é compartilhada na rede de conhecimento da cultura
digital. Além disso, o exercício da autoria mostra-se como uma prática que contribui
para a construção de conhecimento dos alunos, de forma ativa e participante e
apresenta perspectivas que potencializam a integração das TDIC e das mídias
digitais no processo educativo.

Probleminventering av några forskares informationshantering : En fråga för biblioteket? / An inventory of problems found in researchers’ information management processes : A question for the Library?Egevad, Per January 2009 (has links)
The aim of this Master’s thesis is to investigate if the library can be a real partner for researchers in managing and dealing with their research information. In this study, six researchers have been interviewed about their problems with information management. This study uses the method Critical Incident Technique for the interviews with the researchers. This method focuses mainly on problems and what happens around those problems. The interview results have been prepared with automatic clustering and analysed with the help of a theoretical model from Minnesota University Library. This is a model of the scholarly research process described in four overlapping areas: 1) Discover, 2) Gather, 3) Create and 4) Share. The studies result gives that there seems to be no problem with accessing full text information, the problem is rather narrowing down the search to get enough time to read it all. The researchers do not find any search skills in the library that match their own search skills. On the question if the library works well as a partner, the answer in this study is no. The researchers do not see the library as a partner in working with research information, but only as a supplier of documents. When they need assistance, they turn to colleagues, students, email, and as a last resort, the library.

Effects of Police-Mental Health Collaborative Services on Calls, Arrests, and Emergency HospitalizationsZauhar, Sean Russel-Jacque 01 January 2019 (has links)
With the increasing amount of police calls involving persons experiencing a mental health crisis (PICs), agencies are looking for ways to reduce the overuse of emergency services and criminal confinement. Police-mental health collaborative (PMHC) programs were developed to utilize the expertise of both mental health and law enforcement practitioners to provide immediate linkage to psychiatric services in an effort to prevent unnecessary involvement in the criminal justice system. The theoretical framework for this study was built on the sequential intercept model (SIM) along with the theories of social network and social support. The SIM identifies 5 key points where PICs can be diverted away from the criminal justice system. PMHC programs fall within the first intercept where persons with mental illness can be diverted at their first initial contact with law enforcement. Limited empirical research exists that show PMHC programs are reaching their intended objectives. The purpose of this quantitative study was to determine the effect of PMHC services on the likelihood that PICs will have future mental health calls (MHCs), arrests, and emergency hospitalizations (EHPs). Archival data from 1 midwestern police agency and online public court records was used in the analysis. The study employed OLS and logistic regression techniques, which revealed no statistically significant relationships between the PMHC interventions and the likelihood of future MHCs, arrests, and EHPs. However, significance was achieved for several covariates including transient status, prior history of MHCs, arrests, and EHPs. These findings will contribute to positive social change by informing policymakers and practitioners on best practices in community mental health crisis response.

Competency-Based assessment in Australia - does it work?Mhlongo, Nanikie Charity, n/a January 2002 (has links)
South Africa since the liberation in 1994 has faced a lot of changes. The changes
include being a member of the international community. As part of the international
community, South Africa is finding itself largely faced by the challenges associated
with this position. Looking at other countries South Africa is realizing that the world
is looking at better ways of educating their people and organizing their education and
training systems so that they might gain the edge in an increasingly competitive
economic global environment. Success and survival in such a world demands that
South Africa has a national education and training system that provides quality
learning and promotes the development of a nation that is committed to life-long
learning.
Institutions of higher education in South Africa are currently changing their present
education system to conform to a Competency-Based Training (CBT) system. This
system has only been planned but not implemented yet and it is not clear how CBT
will be implemented, especially how the learners are going to be assessed.
Competency-Based Assessment (CBA) is an integral part of CBT that needs
particular attention if the new system is to succeed.
The key aims of this thesis are to investigate the current assessment policy and
practice at the Canberra Institute of Technology (CIT) underpinned by Competency-
Based Training system. The project will describe and analyze the Competency-Based
Assessment system used within CIT's CBT system. The project will focus on:
Observing classroom practice of CBA, analyzing students' and teachers' perceptions
of their involvement with CBA, and analyzing employers' perceptions of the
effectiveness of CBA.
The main aim of this thesis is to suggest recommendations for an assessment model
that will be suitable to implement within hospitality training institutions in South
Africa.

Performance Characterization Of A Cylindrical Ion Trap Mass SpectrometerChatterjee, Saikat 10 1900 (has links)
The cylindrical ion trap (CIT) is made up of two planar endcap electrodes and a cylindrical ring electrode. The investigation of simpler geometries like CIT has been started off in recent years with a view towards miniaturization. As a step towards this, numerical studies on CITs were carried out in our laboratory. Here in this study, our motive is to characterize a CIT through experiments. We have designed a mass spectrometer where a CIT is used as the mass analyzer. The trap performance was observed by varying six parameters associated with our experiment. The parameters are (1) the ionization voltage, (2) the ramp time, (3) the ionization time, (4) the cooling time, (5) the dead time and (6) the bias voltage applied across the filaments. All the experiments have been performed in the mass selective boundary ejection mode.

Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT / Nuklearmedicinska metoder vid idiopatisk Parkinsonism : pre- och postsynaptisk dopamin SPECTJakobson Mo, Susanna January 2013 (has links)
Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis. Clinical differentiation between PD and APD is often difficult in the early stages. The aims of the thesis were to evaluate the differential diagnostic and prognostic value of SPECT in early PD, MSA and PSP, to map the pattern of progression with dopamine SPECT, and map the pattern of dopamine SPECT in non-affected elderly volunteers with a prospective approach. Also, we evaluated the methodological aspects of dopamine SPECT with respect to image evaluation tools, reconstruction parameters and gamma cameras. Methods: 172 patients, included in an on-going clinical prospective study on idiopathic parkinsonism, participated in the SPECT study. Also, 31 age-matched healthy controls (HC) were followed within this study. SPECT was done with 123I-FP-Cit (DAT SPECT) and 123I-IBZM (D2R SPECT). Regions of interest (ROI) were used as a standard method for semi-quantitative image analysis. Results: SPECT uptake ratios from different gamma cameras could be equalised through correction equations derived from images of a brain-like phantom, provided that attenuation correction was applied. The ROI method had high reproducibility. SPECT uptake in HC, measured with the ROI method and a volume based (VOI) method rendered similar trends, but gender and age differences in SPECT uptake were more marked with the VOI method, and less pronounced in DAT SPECT compared to D2R SPECT with both methods. The DAT SPECT uptake was significantly reduced in very early disease stage of PD and APD compared to HC. DATSPECT uptake was more reduced in PD with postural and gait disturbance (PIGD) compared to tremor-dominant PD. Decline in DAT SPECT uptake during the first year was more pronounced in PD and PSP compared to HC. D2R SPECT uptake overlapped between untreated PD and APD. After initiated treatment, the D2R SPECT uptake was significantly higher in MSA patients compared to PD, PSP and HC. Decline in D2R SPECT uptake during the first year was not significantly different between patients or compared to HC. Conclusions: 123I-FP-Cit SPECT is a valuable and sensitive method to detect early stage idiopathic parkinsonism. A different level of uptake between PIGD-PD compared to TD-PD indicates a prognostic potential. It is not possible to differ between PD, MSA and PSP in early stage with 123I-FP-Cit SPECT and no differential diagnostic value was found using 123I-IBZM SPECT in the early, untreated stage of PD, MSA and PSP. A different pattern of uptake of this ligand in MSA compared to PD and PSP during the first years of L-dopa treatment may, however, indicate a diagnostic value during the follow-up period.

Genetic and biochemical dissection of complex evolved traits in bacteriaQuandt, Erik Michael 10 September 2015 (has links)
Evolutionary innovations often arise from complex genetic and ecological interactions, which can make it challenging to understand retrospectively how a novel trait arose. In a long-term experiment, Escherichia coli gained the ability (Cit⁺ ) to utilize abundant citrate in the growth medium after ~31,500 generations of evolution. Exploiting this previously untapped resource was highly beneficial: later Cit⁺ variants achieve a much higher population density in this environment. All Cit⁺ individuals share a mutation that activates aerobic expression of the citT citrate:C₄-dicarboxylate antiporter, but this mutation confers only an extremely weak Cit⁺ phenotype on its own. To determine which of the other >70 mutations in early Cit⁺ clones were needed to take full advantage of citrate, we developed a Recursive Genome-Wide Recombination and Sequencing (REGRES) method and performed genetic backcrosses to purge mutations not required for Cit⁺ from an evolved strain. We discovered a mutation that increased expression of the dctA C₄-dicarboxylate transporter greatly enhanced the Cit⁺ phenotype after it evolved, implicating the intracellular supply of succinate or other C₄-dicarboxylates to be a critical factor for the expression of the phenotype. The activity level of citrate synthase (CS), encoded by the gltA gene, was also found to be important for Cit⁺. A mutation to gltA (gltA1) occurred before the evolution of Cit⁺ and led to an increase in CS activity by diminishing allosteric inhibition by NADH. This mutation was found to be deleterious for high-level citrate utilization, a situation that was remedied shortly after the evolution of Cit⁺ by the evolution of compensatory mutations to gltA which decreased CS activity. We speculate that the gltA1 mutation may have been important to 'potentiate' the evolution of a weak Cit⁺ phenotype by increasing succinate production via an upregulated glyoxylate pathway but that as cells became able to import succinate by virtue of the dctA mutation that this pathway became maladaptive, prompting this evolutionary reversal. Overall, our characterization of this metabolic innovation highlights the degree to which interactions between alleles shape the evolution of complex traits and emphasizes the need for novel whole-genome methods to explore such relationships.

INVESTIGATIONS OF CuInTe2 / CdS & CdTe / CdS HETEROJUNCTION SOLAR CELLSGutta, Venkatesh 01 January 2011 (has links)
Thin film solar cells of Copper Indium Telluride and Cadmium Sulfide junctions were fabricated on plain ITO glass slides and also on those coated with intrinsic Tin Oxide. CdS was deposited through chemical bath deposition and CIT by electrodeposition. Both compounds were subjected to annealing at temperatures between 350°C and 500°C which produced more uniform film thicknesses and larger grain sizes. The CIT/ CdS junction was characterized after performing XRD and spectral absorption of individual compounds.
Studies were also made on CdS / CdTe solar cells with respect to effect of annealing temperatures on open circuit voltages. NP acid etch, the most important process to make the surface of CdTe tellurium rich, was also studied in terms of open circuit voltages. Thermally evaporated CdS of four different thicknesses was deposited on Tin Oxide coated ITO and inferences were drawn as to what thickness of CdS yields better results.
