Interdisciplinary project-based learning: technology for improving student cognition

The article studies a way of enhancing student cognition by using interdisciplinary project-based learning (IPBL) in a higher education institution. IPBL is a creative pedagogic approach allowing students of one area of specialisation to develop projects for students with different academic profiles. The application of this approach in the Ural State University of Economics resulted in a computer-assisted learning system (CALS) designed by IT students. The CALS was used in an analytical chemistry course with students majoring in Commodities Management and Expertise (‘expert’ students). To test how effective the technology was, the control and experimental groups were formed. In the control group, learning was done with traditional methods. In the experimental group, it was reinforced by IPBL. A statistical analysis of the results, with an application of Pearson χ 2 test, showed that the cognitive levels in both IT and ‘expert’ experimental groups improved as compared with the control groups. The findings demonstrated that IPBL can significantly enhance learning. It can be implemented in any institution of higher or secondary education that promotes learning, including the CALS development and its use for solving problems in different subject areas.

‘Driving Forces of Investment Decisions in Mutual Funds’

Unfortunately, in India it is a fact that most of the investors are not interested in mutual funds. Those who are investing, they are investing only very small amounts. But what is important to be noted here is that when compared to other financial instruments, investments in mutual funds are safer and also yields more returns on the investment portfolio. Moreover as an investment avenue mutual fund is available for those investors who are not willing to take any exposure directly in the security market. It also helps such investors to build their wealth over a period of time. At the retail level, investors are unique and are highly heterogeneous, and the mutual fund schemes' selection will also differ depends on their expectations. Hence, investors’ expectation is a very important factor in this regard that needs to be analysed by all the investment houses. Hence, the factors that drive the investment decisions of individual investors to meet their expectations by investing money in mutual funds need an in-depth analysis. These driving forces include the preference of investors on mutual fund compared to various available avenues of financial investments, risk attitude of investors, influence of characteristics of instruments of mutual funds on investors, the investment specific attitudes of investors, and influence of qualities of fund management on investors. The success of any mutual fund, a popular means of investment, depends on how effectively an Asset Management Company has been able to understand the level of influence of these factors on the decision of investors to invest in mutual funds. For a substantial growth in the mutual fund market, there must be a high level precision in the design and marketing of the products of mutual funds taking into account these driving forces by the Asset Management Companies. Therefore, there is a need to conduct a detailed study on investments in mutual funds in this direction. A review of available literature also revealed that no detailed study on mutual funds has so far been attempted in this direction; hence the present study on Driving Forces of Investment Decisions in Mutual Funds is undertaken.

Políticas educacionais para a educação tecnológica: a proposta do Curso Superior de Tecnologia em Gestão de Recursos Humanos da FAP e o histórico dualismo da educação brasileira

O presente estudo analisou as políticas públicas voltadas para a Educação Profissional e Tecnológica e sua influência sobre o projeto pedagógico do Curso Superior de Tecnologia em Gestão de Recursos Humanos da Faculdade do Pará e, em particular, como este Curso se apresenta ante ao histórico processo dual de oferta da educação no Brasil. Para tanto, analisamos o conteúdo das políticas públicas voltadas para a educação Profissional e Tecnológica no Brasil, a partir da década de 1990. Utilizamos os procedimentos da pesquisa qualitativa, fazendo uso de entrevistas e de análise documental, para analisar o nosso objeto. Partimos da hipótese segundo a qual as políticas de educação profissional e tecnológica de nosso país pressupõem a formação especificamente para o trabalho e visam a conformação das classes sociais fundamentais, proprietárias e não-proprietárias, e que o Curso Superior de Tecnologia em Gestão de Recursos Humanos da Faculdade do Pará fortalece esta mesma perspectiva político-pedagógica. Analisamos os documentos que normatizam os cursos superiores de tecnologia no Brasil, o projeto pedagógico e o desenho curricular do curso em questão e as falas de professores, técnicos, egressos e gestores da instituição à luz de autores identificados com o materialismo histórico. Verificamos que, tanto os documentos normatizadores da educação profissional tecnológica brasileira quanto àqueles que definem a estrutura do curso estudado na Faculdade do Pará têm sido orientados para o desenvolvimento do “fazer”, do “saber-fazer”, não dando conta das bases científicas deste fazer e nem de uma formação que considere as relações histórico-sociais nas quais está inserido. Assim, o direcionamento dado à formação de tecnólogos tem, fundamentalmente, promovido a capacidade de aprendizagem dos processos tecnológicos específicos, incentivando à produção e a inovação científico-tecnológica e suas aplicações no mundo do trabalho, visando o desenvolvimento de competências profissionais tecnológicas, gerais e específicas. Concluímos nosso estudo com a convicção de que o conteúdo das políticas para a educação profissional e tecnológica bem como do Curso Superior de Tecnologia em Gestão de Recursos Humanos fortalecem a histórica dualidade da educação brasileira ao se orientarem apenas para a conformação dos processos formativos as demandas dos setores produtivos e para a aquisição de conhecimentos relativos, unicamente, ao desenvolvimento de funções específicas.

J/psi Polarization in pp Collisions at root s=7 TeV

The ALICE Collaboration has studied J/psi production in pp collisions at root s = 7 TeV at the LHC through its muon pair decay. The polar and azimuthal angle distributions of the decay muons were measured, and results on the J/psi polarization parameters lambda(theta) and lambda(phi) were obtained. The study was performed in the kinematic region 2: 5 < y < 4, 2 < p(t) < 8 GeV/c, in the helicity and Collins-Soper reference frames. In both frames, the polarization parameters are compatible with zero, within uncertainties.

The Accuracy and Reliability of Traditional Surface Flow Type Mapping: Is It Time for A New Method of Characterising Physical River Habitat?

Surface flow types (SFT) are advocated as ecologically relevant hydraulic units, often mapped visually from the bankside to characterise rapidly the physical habitat of rivers. SFT mapping is simple, non-invasive and cost-efficient. However, it is also qualitative, subjective and plagued by difficulties in recording accurately the spatial extent of SFT units. Quantitative validation of the underlying physical habitat parameters is often lacking, and does not consistently differentiate between SFTs. Here, we investigate explicitly the accuracy, reliability and statistical separability of traditionally mapped SFTs as indicators of physical habitat, using independent, hydraulic and topographic data collected during three surveys of a c. 50m reach of the River Arrow, Warwickshire, England. We also explore the potential of a novel remote sensing approach, comprising a small unmanned aerial system (sUAS) and Structure-from-Motion photogrammetry (SfM), as an alternative method of physical habitat characterisation. Our key findings indicate that SFT mapping accuracy is highly variable, with overall mapping accuracy not exceeding 74%. Results from analysis of similarity (ANOSIM) tests found that strong differences did not exist between all SFT pairs. This leads us to question the suitability of SFTs for characterising physical habitat for river science and management applications. In contrast, the sUAS-SfM approach provided high resolution, spatially continuous, spatially explicit, quantitative measurements of water depth and point cloud roughness at the microscale (spatial scales ≤1m). Such data are acquired rapidly, inexpensively, and provide new opportunities for examining the heterogeneity of physical habitat over a range of spatial and temporal scales. Whilst continued refinement of the sUAS-SfM approach is required, we propose that this method offers an opportunity to move away from broad, mesoscale classifications of physical habitat (spatial scales 10-100m), and towards continuous, quantitative measurements of the continuum of hydraulic and geomorphic conditions which actually exists at the microscale.

IT Adoption and Usage in Non-Profit Organizations: a Cross-generational Case Study

A gulf has tended to develop between the adoption and usage of information technology by different generations, at the heart of which is different ways of experiencing and relating to the world around us. This research idea is currently being developed following data collection and feedback is sought on ways forward to enable impact. The research focuses on information technology in the form of multimedia. Multimedia meaning ‘media’ and ‘content’ that uses a combination of different content forms; or electronically integrated communication engaging all or most of the senses (e.g. graphic art, sound, animation and full-motion video presented by way of computer or other electronic means) mainly through presentational technologies. Although multimedia is not new, some organization’s particularly those in the non-profit sector do not always have the technical or financial resources to support such systems and consequently may struggle to adopt and support its usage amongst different generations. However non-profit organizations are being forced to pay more attention to the way they communicate with markets and the public due to the professionalism of communication everywhere in society. The case study used for this study is a church circuit comprising of 15 churches in the Midlands region of the United Kingdom which was selected due to the diverse age groups catered for within this type of non-profit organization. Participants in the study also had a range of skills, experiences and backgrounds which adds to the diversity of the population studied. Data gathered focused on the attitudes and opinions of the adoption and use of multimedia amongst different age groups. 395 questionnaires were distributed, comprising of 11 opinion questions and 4 demographic questions. 83% of the questionnaires were returned, representing 35% of the total circuit membership. Three people from each of the following age categories were also interviewed: 1920 – 1946 (Matures); 1947-1964 (Baby Boomers); 1965-1982 (Generation X); 1983-2004 (Net Generation). Results of the questionnaire and comments from the interviews were found not to tally with the widespread assumption that the younger generation is attracted by the use of multimedia in comparison to the older generation. The highest proportion of those who said that they gain more from a service enhanced by multimedia was from the Baby Boomers. Comments from interviews suggested that: ‘we need to embrace multimedia if we are to attract and retain the younger generation’; ‘multimedia often helps children to remain focused and clarifies the objective of the service’. However, because the younger generations’ world tends to be dominated by computer technology the questionnaire showed that they are more likely to have higher standards when it comes to the use of multimedia, such as identifying higher levels of equipment failing to work and annoying use of sounds compared to older age groups. In comparison problems experienced with multimedia for the Matures age group had the highest percentage of difficulty with the size of letters; the colour of letters and background and the sound not loud enough which is to be expected. Since every organization is unique any type of multimedia adopted and used should be specific to their needs, its stakeholders and the physical building in order to enhance that uniqueness and its needs. Giving thought to whether the type of multimedia is the best method for communicating the message to the particular audience alongside how technical and financial resources are best used can assist in accommodating different age groups that need to be catered for.

The Use of a Computer-Based Simulation Game (CSG) for Learning and Teaching

Introduction A computer-based simulation game (CSG) was used for the first time in a final-year undergraduate module. A change management simulation game was used in the seminar classes as a formative exercise that was linked to parts of the students’ summative assessment. The module evaluation suggests that most students learned from using the CSG.
