Property Education : an evaluation of how well undergraduate property students are prepared for commencing their careers

The evolution of property education to adapt to the changing business environment requires changes to course content, method of delivery and assessment. Many universities have a special interest in understanding how the students transition in and transition out of the property programs. The impact of the first year student experience is often easier to assess through students’ progression in the course and performance in their intermediate and advanced units. However, the students’ success in transitioning from university student to property professional is often more difficult to determine. In an environment where many property students commence their professional careers while still completing their undergraduate property qualification, a survey of current final year students was undertaken to identify the students’ perception of their level of preparedness for entry into the professional world. This study has also been informed by feedback received from and informal discussions held with industry representative bodies, alumni and senior members of professional organisations. The QUT UD40 Bachelor of Urban Development, Property Economics course has been designed to achieve graduate capabilities in core technical skills and generic professional skills which are required by property professionals. The results of this study were that some units in the program were perceived to provide direct preparation for students commencing their professional careers whilst the impact of other units was less tangible. Valuable feedback received during the study included an assessment of the relevance of many multi-disciplinary units, the appropriateness of the programming of units within the course and the appropriateness of repetition of content during the course. The further research question arises as to how universities can better assist students in the transition to the professional environment when frequently this occurs prior to completion of the property course.

Recommending best answer in a collaborative question answering system

The World Wide Web has become a medium for people to share information. People use Web-based collaborative tools such as question answering (QA) portals, blogs/forums, email and instant messaging to acquire information and to form online-based communities. In an online QA portal, a user asks a question and other users can provide answers based on their knowledge, with the question usually being answered by many users. It can become overwhelming and/or time/resource consuming for a user to read all of the answers provided for a given question. Thus, there exists a need for a mechanism to rank the provided answers so users can focus on only reading good quality answers. The majority of online QA systems use user feedback to rank users’ answers and the user who asked the question can decide on the best answer. Other users who didn’t participate in answering the question can also vote to determine the best answer. However, ranking the best answer via this collaborative method is time consuming and requires an ongoing continuous involvement of users to provide the needed feedback. The objective of this research is to discover a way to recommend the best answer as part of a ranked list of answers for a posted question automatically, without the need for user feedback. The proposed approach combines both a non-content-based reputation method and a content-based method to solve the problem of recommending the best answer to the user who posted the question. The non-content method assigns a score to each user which reflects the users’ reputation level in using the QA portal system. Each user is assigned two types of non-content-based reputations cores: a local reputation score and a global reputation score. The local reputation score plays an important role in deciding the reputation level of a user for the category in which the question is asked. The global reputation score indicates the prestige of a user across all of the categories in the QA system. Due to the possibility of user cheating, such as awarding the best answer to a friend regardless of the answer quality, a content-based method for determining the quality of a given answer is proposed, alongside the non-content-based reputation method. Answers for a question from different users are compared with an ideal (or expert) answer using traditional Information Retrieval and Natural Language Processing techniques. Each answer provided for a question is assigned a content score according to how well it matched the ideal answer. To evaluate the performance of the proposed methods, each recommended best answer is compared with the best answer determined by one of the most popular link analysis methods, Hyperlink-Induced Topic Search (HITS). The proposed methods are able to yield high accuracy, as shown by correlation scores: Kendall correlation and Spearman correlation. The reputation method outperforms the HITS method in terms of recommending the best answer. The inclusion of the reputation score with the content score improves the overall performance, which is measured through the use of Top-n match scores.

Leveraging the network information for evaluating answer quality in a collaborative question answering portal

Collaborative question answering (cQA) portals such as Yahoo! Answers allow users as askers or answer authors to communicate, and exchange information through the asking and answering of questions in the network. In their current set-up, answers to a question are arranged in chronological order. For effective information retrieval, it will be advantageous to have the users’ answers ranked according to their quality. This paper proposes a novel approach of evaluating and ranking the users’answers and recommending the top-n quality answers to information seekers. The proposed approach is based on a user-reputation method which assigns a score to an answer reflecting its answer author’s reputation level in the network. The proposed approach is evaluated on a dataset collected from a live cQA, namely, Yahoo! Answers. To compare the results obtained by the non-content-based user-reputation method, experiments were also conducted with several content-based methods that assign a score to an answer reflecting its content quality. Various combinations of non-content and content-based scores were also used in comparing results. Empirical analysis shows that the proposed method is able to rank the users’ answers and recommend the top-n answers with good accuracy. Results of the proposed method outperform the content-based methods, various combinations, and the results obtained by the popular link analysis method, HITS.

REHTORIT PORTINVARTIJOINA : sekä miten rehtoreiden kertomuksista muodostuu pääkaupunkiseudun Tehostetun ja erityisen tuen kehittämisverkoston tarina

Research objectives. The Special Education Strategy, the legislative change based on it, and the change in the Finnish National Core Curriculum for Pre-primary and Basic Education build the background for this study. An improvement initiative called KELPO was founded in 2008 to implement a new three-level support system in municipalities. To support this initiative, the Network of Intensified and Special Support in the Metropolitan Area was founded in 2010. The Network consists of 22 pilot schools from four metropolitan municipalities and the Centre for Educational Assessment at the University of Helsinki that carries out the developmental assessment of the initiative. The objective of my study was to form an overall view of the functioning of the Network. The data included interviews of 20 principals of the schools belonging to the Network. The interviews were conducted by the Centre for Educational Assessment in the autumn of 2010. The research question is: What do principals speak about the networking done inside and between the municipalities? Methods. I received the data as already transcribed for my use. I researched it using a narrative research approach. As a method I used both thematic reading and classifying narratives by the holistic-content. These methods belong under the analyze of narratives. I collected the narratives from the principals under themes that arose from the data delimited by my research question. The narrative analysis materialized by writing the research story, as a new story was built by the principals stories theme by theme. The classification of the narratives by the holistic-content method was realized according to what kind of a gatekeeper s role each principal had. With a gatekeeper I here mean the intermediary role of a principal between the school and outside world. In addition, I used the analysis of interactive production of the narrative when applicable. Results and conclusions. Explicit features in the story of the Network were the principals at least partial uncertainty of the purpose of the networking, lack of time and resources, changing of initiatives, and lack of continuity. Positive narratives about ownership and empowerment could also be found. Nonetheless, many of the preconditions for success described by the school reform and school networking theories were not fulfilled. According to the collective story, there was no shared goal or purpose, and nor were the needs of autonomy, competence, and relatedness fulfilled. Three different kinds of gatekeepers were found in the data: The Exemplary ones, The Survivors and The Losers. The distinguishing factor turned out to be sharing of information at school. Based on the narratives, the schools with principals taking care of sharing information were the most active in partaking in networking.

O raciocínio clínico do enfermeiro na avaliação de feridas em clientes com afecções oncológicas

Estudo de natureza qualitativa, descritiva e exploratória, que teve como objeto o raciocínio clínico elaborado pelos enfermeiros ao cuidarem de feridas em clientes com afecções oncológicas. Os objetivos traçados para o estudo foram: identificar as estratégias cognitivas que os enfermeiros com especialização em área oncológica consideram adotar para o estabelecimento de um julgamento clínico na avaliação de feridas em clientes com afecções oncológicas e caracterizar as etapas de elaboração mental para construção do raciocínio clínico que os enfermeiros consideram percorrer quando da avaliação de feridas em cliente acometido por afecções oncológicas. O campo de pesquisa foi o Instituto Nacional do Câncer, no qual os cenários de coleta foi a unidade HC-I nas Seções de Oncologia Clínica, Neurocirurgia, Abdominopélvica, Centro de Tratamento Intensivo e Cirurgia de Cabeça e Pescoço. Os sujeitos do estudo foram treze enfermeiros com especialização em oncologia, que assistiam clientes com afecções oncológicas, há pelo menos cinco anos. A coleta dos dados aconteceu nos meses de junho e julho de 2009, sendo utilizado um roteiro de entrevista semi-estruturada para captar as informações. A análise dos dados foi realizada com base no método de análise de conteúdo, que ao ser aplicado possibilitou a apreensão de quatro categorias: (1) a afecção oncológica como fator expressivo na elaboração mental diagnóstica do enfermeiro; (2) a relevância do conhecimento teórico-prático avançado para a elaboração mental avaliativa do enfermeiro; (3) a construção da elaboração mental para o raciocínio clínico diagnóstico do enfermeiro; (4) a importância da interação humana no contexto avaliativo. Concluiu-se que, este estudo identificou, na discussão das categorias, as quatro principais estratégias cognitivas que os enfermeiros com especialização em área oncológica consideram adotar para o estabelecimento de um julgamento clínico na avaliação de feridas em clientes com afecções oncológicas e caracterizou as etapas de elaboração mental para construção do raciocínio clínico diagnóstico do tipo hipotético-dedutivo e intuitivo. Compreendeu-se que os sujeitos da pesquisa detêm qualidades intelectuais específicas e avançadas, quando elaboram diagnósticos e intervenções baseadas nas respostas humanas em situação de avaliação de feridas nos clientes com doença oncológica, e foi considerado que o ensino pode impulsionar o desenvolvimento das competências cognitivas no sentido de formar profissionais capazes de avaliar o próprio conhecimento, bem como a fomentação de novas pesquisas relativas a essa temática imprescindível para uma assistência de enfermagem qualificada.

A influência do movimento renovador em aulas de educação física de escolas municipais do Rio de Janeiro

Como crítica à perspectiva da Educação Física Escolar (EFE) voltada à aptidão física e ao desenvolvimento técnico-esportivo, tão comum até a década de 1970, surgem, a partir da década de 1980, novas propostas de ensino que a aproximariam dos reais objetivos da escola é o que se chama de movimento renovador da EFE. Ao longo dos anos, essas propostas foram incorporadas aos cursos de graduação, de pós-graduação e aos documentos oficiais de ensino. Era de se esperar que as aulas de EFE nas escolas brasileiras, hoje, representassem, hegemonicamente, as propostas do movimento renovador, mas paradoxalmente temos visto intervenções difusas e até aleatórias, muitas vezes representadas pelo rola a bola. Diante da necessidade de investir em práticas renovadoras e a fim de abolir o caráter de estudos que apenas pomovem denúncias de práticas caducas, este estudo buscou professores que, alinhados aos conhecimentos renovadores, procuram desenvolver aulas de EFE que se aproximam e representam tais conhecimentos didático-metodológicos. Assim, buscou-se investigar a influência do movimento renovador na intervenção pedagógica de cinco professores de Educação Física da rede municipal de ensino do Rio de Janeiro. O estudo divide-se em três artigos complementares. O primeiro traz a problematização e a revisão bibliográfica. O segundo busca identificar o que os professores pensam acerca do movimento renovador, bem como analisar características acadêmicas e profissionais-interventivas. Os resultados do artigo 2 apontam que os professores parecem conhecer, se alinham e afirmam ministrar aulas em acordo com as propostas renovadoras, mas possuem ambientes e condições de trabalho distintas. O terceiro artigo traz a análise de 20 aulas de EFE dos cinco professores, a partir de uma ficha de observação sistemática composta por indicadores didático-metodológicos sugeridos por Resende e Nascimento (2004), além da discussão de uma entrevista sobre questões didáticas e metodológicas e críticas às intervenções. Percebeu-se que, apesar de intervenções com características distintas, a maioria das ações intervetivas se aproximou dos indicadores nas categorias planejamento, objetivo, conteúdo, método, avaliação e relação professor-aluno. Todos os professores fizeram críticas às aulas, acreditando que estas deveriam ser melhores e diferentes do que frequentemente são, o que representa limitações do campo interventivo e o compromisso dos professores com a qualidade da intervenção. Acredita-se que os dados deste estudo representam mais um pequeno passo às discussões e construções de práticas renovadoras no campo da EFE, ao buscar e apontar possibilidades, limitações e exemplos de ações didáticas concretas do cotidiano.

A PPCCIPS: a Política Pública da Coleta Complementar Itinerante e Programada de Sangue, sob a luz da teoria do ciclo da política pública

This study aimed to focus on aspects of public administration concerning the implementation of the public policy of complementary blood collection by the itinerant and scheduled PPCCIPS services either trough off local unity or mobile unit blood collection operations, which are managed by the State Institute of Hematology Arthur de Siqueira Cavalcanti - HEMORIO. The case study method was used in that public health institutional field, in search for a better understanding of responsibilities and management related to collection, serology, fractionation, storage and distribution of blood supply to almost all public hospitals and clinics, summed up to agreements with the single health system of the State of Rio de Janeiro. Bibliographic references, documentary and field data obtained through interviews and systematic observation in the public servants of HEMORIO workplaces, were treated by the analysis of the content method and the results of this research revealed the complexity of those services, and needs in outstanding aspects of infrastructure, equipment, logistics and personnel, which are critical for the achievement of the increased public collection of blood in the Rio de Janeiro State, endorsing the suggestions for the implementation of PPCCIPS in HEMORIO. The main point found in this research results concern the immanent ethical commitment of that public service personnel, including staff members and low ranking members as well, perceived due to a brief philosophical overlook on that personnel¿s attitudes. An important strategic aspect was revealed by the need for excellence of midia communications and education programs to implement the community involvement in the whole process. Final reflections point out that personnel posture is considered vital for the quality of the expected care of the technical activities and also for the quality of its final products release to the local public, fluminense, which is the irreplaceable human blood, and their derivatives. Despite the author¿s effort in this dissertation there is much more to be studied on that crucial theme.

Motivos da recusa à doação de órgãos apontados familiares de pessoas com morte encefálica

Purpose: Study aiming to understand the reasons for the refusal to donate organs by relatives of potential donors living in the Mid-Western region of the São Paulo state. Method: Qualitative study performed after data collection by the Organ Procurement Organization (OPO) Division of a reference hospital in the region. Relatives were contacted to participate in a semi-structured interview, and after the subjects in the study were characterized, four guiding questions were presented; their respective answers were recorded to be transcribed later. The Analysis of Content method proposed by Bardin was used to organize the speeches. Results: From 2006 to 2008, 30 (35.3%) families contacted by OPO have refused to agree with the organ donation. From that universe, 16 family members were interviewed. Data was systematized in three major themes: The experience of being informed on a family member’s brain death, decision concerning to the organ donation and aspects that would facilitate the decision to agree with the organ donation. Conclusion: the identification of reasons for the refusal and the suggestions presented has provided subsidies to improve the organ donation for transplantation process.

Non-Destructive Method to Estimate the Moisture Content in Bread using Multi-Channel Electrical Impedance Spectroscopy

Bread undergoes several physicochemical changes during storage that results in a rapid loss of freshness. These changes depend on moisture content present in bread product. An instrument based on electrical impedance spectroscopy technique is developed to estimate moisture content of bread at different zones using designed multi-channel ring electrodes. A dedicated AT89S52 microcontroller and associated peripherals are employed for hardware. A constant current is applied across bread loaf through central pair of electrodes and developed potential across different zones of bread loaf are measured using remaining four ring electrode pairs. These measured values of voltage and current are used to measure the impedance at each zone. Electrical impedance behavior of the bread loaf at crust and crumb is investigated during storage. A linear relationship is observed between the measured impedance and moisture content present in crust and crumb of bread loaf during storage of 120 hours.

Introduction of high-content screening method for studying drug-induced mitochondrial dysfunction in hepatocytes

Drug induced liver injury is one of the frequent reasons for the drug removal from the market. During the recent years there has been a pressure to develop more cost efficient, faster and easier ways to investigate drug-induced toxicity in order to recognize hepatotoxic drugs in the earlier phases of drug development. High Content Screening (HCS) instrument is an automated microscope equipped with image analysis software. It makes the image analysis faster and decreases the risk for an error caused by a person by analyzing the images always in the same way. Because the amount of drug and time needed in the analysis are smaller and multiple parameters can be analyzed from the same cells, the method should be more sensitive, effective and cheaper than the conventional assays in cytotoxicity testing. Liver cells are rich in mitochondria and many drugs target their toxicity to hepatocyte mitochondria. Mitochondria produce the majority of the ATP in the cell through oxidative phosphorylation. They maintain biochemical homeostasis in the cell and participate in cell death. Mitochondria is divided into two compartments by inner and outer mitochondrial membranes. The oxidative phosphorylation happens in the inner mitochondrial membrane. A part of the respiratory chain, a protein called cytochrome c, activates caspase cascades when released. This leads to apoptosis. The aim of this study was to implement, optimize and compare mitochondrial toxicity HCS assays in live cells and fixed cells in two cellular models: human HepG2 hepatoma cell line and rat primary hepatocytes. Three different hepato- and mitochondriatoxic drugs (staurosporine, rotenone and tolcapone) were used. Cells were treated with the drugs, incubated with the fluorescent probes and then the images were analyzed using Cellomics ArrayScan VTI reader. Finally the results obtained after optimizing methods were compared to each other and to the results of the conventional cytotoxicity assays, ATP and LDH measurements. After optimization the live cell method and rat primary hepatocytes were selected to be used in the experiments. Staurosporine was the most toxic of the three drugs and caused most damage to the cells most quickly. Rotenone was not that toxic, but the results were more reproducible and thus it would serve as a good positive control in the screening. Tolcapone was the least toxic. So far the conventional analysis of cytotoxicity worked better than the HCS methods. More optimization needs to be done to get the HCS method more sensitive. This was not possible in this study due to time limit.
