A combined spectrophotometric and morphometric study of the lunar mare dome fields near Cauchy, Arago, Hortensius, and Milichius

In this Study we examine the spectral and morphometric properties of the four important lunar mare dome fields near Cauchy, Arago, Hortensius. and Milichius. We utilize Clementine UV vis mulfispectral data to examine the soil composition of the mare domes while employing telescopic CCD imagery to compute digital elevation maps in order to determine their morphometric properties, especially flank slope, height, and edifice Volume. After reviewing previous attempts to determine topographic data for lunar domes, we propose an image-based 3D reconstruction approach which is based on a combination of photoclinometry and shape from shading. Accordingly, we devise a classification scheme for lunar Marc domes which is based on a principal component analysis of the determined spectral and morphometric features. For the effusive mare domes of the examined fields we establish four Classes, two of which are further divided into two subclasses, respectively, where each class represents distinct combinations of spectral and morphometric dome properties. As a general trend, shallow and steep domes formed out of low-TiO2 basalts are observed in the Hortensius and Milichius dome fields, while the domes near Cauchy and Arago that consist of high-TiO2 basalts are all very shallow. The intrusive domes of our data set cover a wide continuous range of spectral and morphometric quantities, generally characterized by larger diameters and shallower flank slopes than effusive domes. A comparison to effusive and intrusive mare domes in other lunar regions, highland domes, and lunar cones has shown that the examined four mare dome fields display Such a richness in spectral properties and 3D dome shape that the established representation remains valid in a more global context. Furthermore, we estimate the physical parameters of dome formation for the examined domes based on a rheologic model. Each class of effusive domes defined in terms of spectral and morphometric properties is characterized by its specific range of values for lava viscosity, effusion rate, and duration of the effusion process. For our data set we report lava viscosities between about 10(2) and 10(8) Pas, effusion rates between 25 and 600 m(3) s(-1), and durations of the effusion process between three weeks and 18 years. Lava viscosity decreases with increasing R-415/R-750 spectral ratio and thus TiO2 content; however, the correlation is not strong, implying an important influence of further parameters like effusion temperature on lava viscosity.

Generative acts: Family and community involvement of older Australians

The article adopts a developmental approach to successful human aging by exploring the concept of generativity in relation to a study of older Australians' lived experiences of involvement in the family and community. Qualitative data, collected through focus group interviews, were analyzed interpretively using recent developments in Erikson's theory of generativity as a framework. As a result, the present study contributes an in-depth understanding of the role of generative acts to the lives of older people. The data provide illustrative support for Erikson's contention of a generativity/stagnation crisis in later life. Involvement in the family and community is seen as a productive and generative activity, which promotes a positive experience of aging. Two further emergent themes are also explored. First, the experiences of study participants illustrate the reciprocal and cyclical nature of grand-generativity, and the importance of intergenerational relationships. Finally, the data contribute to our knowledge of cultural generativity, and in particular the passing on of cultural knowledge through narratives and modeling.

Engaging game characters: Informing design with player perspectives

The behavior of characters in current computer games is generally scripted and predictable. This paper discusses some issues related to creating game characters that enhance player engagement and identifies the need for a more player-centered approach to game character design. This paper reports the results of a focus group that was carried out with experienced game players to determine what game character behaviors would enhance their engagement in a game. The four general areas of concern that came out of this discussion were consistency with context, player expectations, social interactions and consistency with the environment. This paper discusses these issues and their implication for game character design with a view to creating engaging game characters. © Springer

INTERVENÇÃO LÚDICO-SIMBÓLICA JUNTO A PORTADORES DE DISPEPSIA FUNCIONAL

O presente estudo aborda uma intervenção grupal lúdico-simbólica junto a portadores de dispepsia funcional (DF), um distúrbio gastrointestinal caracterizado por sintomas como dor ou desconforto na região superior do abdômen, sem causa orgânica. Tem como objetivo intervir de forma grupal lúdicosimbólica junto ao portador de DF; analisar o nível de estresse dessa população e relacionar os dados da intervenção frente o nível de estresse. Trata-se de pesquisa exploratório-descritiva de caráter qualitativo. A intervenção grupal utiliza-se de técnicas de imaginação e pensamento dirigido; o nível de stress é avaliado através do Inventário de Sintomas de Stress para adultos de LIPP (ISSL). Os participantes do grupo são 12, predominantemente do sexo feminino, sendo a metade entre 20 e 50 anos e os demais, acima. Através da análise de conteúdo dos dados da entrevista dirigida pôde-se observar que todos fizeram uma associação do aparecimento dos sintomas a conflitos emocionais, focalizando cenas e situações como fatores estressores e desencadeadores da dispepsia funcional. A análise simbólica das intervenções grupais tem como base teórica a psicologia analítica de Carl Gustav Jung. Os resultados demonstraram que os participantes da intervenção grupal apresentaram redução dos sintomas da dispepsia funcional e do nível de estresse, sendo que, no início oito participantes encontravam-se na fase de resistência; um na de alerta e três sem estresse e, ao final, três se encontram na fase de resistência, um permanece na fase alerta e oito sem estresse. Essa transformação ocorreu após terem considerado os sintomas como símbolos de emoções e sentimentos através das intervenções lúdico-simbólicas, e após tê-los integrados à consciência ao fazerem conexões psíquicas entre mente e corpo para reconhecerem atitudes tomadas ou a tomar e agilizar enfrentamentos para não cristalizar sintomas da dispepsia funcional, do ponto de vista da psicologia analítica.

'He was like a zombie':off-label prescription of antipsychotic drugs in dementia

This paper explores the legal position of the off-label prescription of antipsychotic medications to people with dementia who experience behavioural and psychological symptoms of dementia (BPSD). Dementia is a challenging illness, and BPSD can be very difficult for carers to manage, with evidence that this contributes to carer strain and can result in the early institutionalisation of people with dementia. As a result, the prescription of antipsychotic and other neuroleptic medications to treat BPSD has become commonplace, in spite of these drugs being untested and unlicensed for use to treat older people with dementia. In recent years, it has become apparent through clinical trials that antipsychotic drugs increase the risk of cerebrovascular accident (stroke) and death in people with dementia. In addition, these types of medication also have other risk factors for people with dementia, including over-sedation and worsening of cognitive function. Drawing on recent questionnaire (n = 185), focus group (n = 15), and interview (n = 11) data with carers of people with dementia, this paper explores the law relating to off-label prescription, and the applicability of medical negligence law to cases where adverse events follow the use of antipsychotic medication. It is argued that the practice of off-label prescribing requires regulatory intervention in order to protect vulnerable patients. © The Author [2012].

Forms of capital, mixed embeddedness and Somali enterprise

What form is small business activity taking among new migrants in the UK? This question is addressed by examining the case of Somalis in the English city of Leicester.We apply a novel synthesis of the Nee and Sanders' (2001) `forms of capital' model with the `mixed embeddedness' approach (Rath, 2000) to enterprises established by newly arrived immigrant communities, combining agency and structure perspectives. Data are drawn from business-owners (and workers) themselves, rather than community representatives. Face-to-face in-depth interviews were held with 25 business owners and 25 employees/`helpers', supplemented by 3 focus group encounters with different segments of the Somali business population.The findings indicate that a reliance solely on social capital explanations is not sufficient. An adequate understanding of business dynamics requires an appreciation of how Somalis mobilize different forms of capital within a given political, social and economic context.

Children's views on unlicensed/off-label paediatric prescribing and paediatric clinical trials

Objectives - To explore the views and perspectives of children on the unlicensed/off-label use of medicines in children and on the participation of children in clinical trials. Methods - Focus-group discussions, involving school children, were carried out in a range of primary and secondary schools in Northern Ireland. A purposeful sample was chosen to facilitate representation of various socioeconomic groupings. Results - A total of 123 pupils, aged from 10 to 16 years, from six schools, participated in 16 focus groups. In general, pupils viewed the unlicensed/off-label use of medicines in children as unsafe and unethical and felt it is necessary to test medicines in children to improve the availability of licensed products. The majority felt that older children should be told, and that parents should be told, about the unlicensed/off-label use of medicines in children, yet they recognised some implications of this, such as potential medication non-adherence. Conclusions - This is the first study to explore the views of healthy children on unlicensed medicine use in children. Children were able to recognise potential risks associated with the unlicensed use of medicines and felt it is necessary to test and license more medicines in children. Practice implications - Health care professionals should consider the views of children in decisions that affect their health.

Managing project risk using combined analytic hierarchy process and risk map

The main purpose of the study is to develop an integrated framework for managing project risks by analyzing risk across project, work package and activity levels, and developing responses. Design/methodology/approach: The study first reviews the literature of various contemporary risk management frameworks in order to identify gaps in project risk management knowledge. Then it develops a conceptual risk management framework using combined analytic hierarchy process (AHP) and risk map for managing project risks. The proposed framework has then been applied to a 1500 km oil pipeline construction project in India in order to demonstrate its effectiveness. The concerned project stakeholders were involved through focus group discussions for applying the proposed risk management framework in the project under study. Findings: The combined AHP and risk map approach is very effective to manage project risks across project, work package and activity levels. The risk factors in project level are caused because of external forces such as business environment (e.g. customers, competitors, technological development, politics, socioeconomic environment). The risk factors in work package and activity levels are operational in nature and created due to internal causes such as lack of material and labor productivity, implementation issues, team ineffectiveness, etc. Practical implications: The suggested model can be applied to any complex project and helps manage risk throughout the project life cycle. Originality/value: Both business and operational risks constitute project risks. In one hand, the conventional project risk management frameworks emphasize on managing business risks and often ignore operational risks. On the other hand, the studies that deal with operational risk often do not link them with business risks. However, they need to be addressed in an integrated way as there are a few risks that affect only the specific level. Hence, this study bridges the gaps. © 2010 Elsevier B.V. All rights reserved.

What do students really think? Understanding postgraduate students' perception of service quality

This paper explores the components of Service Quality in HE from the Business School Postgraduate student perspective. A six-dimensional scale measuring Service Quality is developed based on focus group and survey data. Our findings highlight that postgraduate students are highly outcome oriented; the award of a reputable degree to gain employment is more important than learning for life. Whilst developing employable graduates, Business Schools must not neglect the core service; teaching & learning. In the long-term this contributes to employability rates and the reputation of institutions. However, as student satisfaction is an increasingly paramount objective, balancing the core service and factors perceived as important by postgraduate students is key.

Perspectives of carers on medication management in dementia:lessons from collaboratively developing a research proposal

Background: The need for carers to manage medication-related problems for people with dementia living in the community raises dilemmas, which can be identified by carers and people with dementia as key issues for developing carer-relevant research projects.A research planning Public Patient Involvement (PPI) workshop using adapted focus group methodology was held at the Alzheimer's Society's national office, involving carers of people with dementia who were current members of the Alzheimer's Society Research Network (ASRN) in dialogue with health professionals aimed to identify key issues in relation to medication management in dementia from the carer viewpoint. The group was facilitated by a specialist mental health pharmacist, using a topic guide developed systematically with carers, health professionals and researchers. Audio-recordings and field notes were made at the time and were transcribed and analysed thematically. The participants included nine carers in addition to academics, clinicians, and staff from DeNDRoN (Dementias and Neurodegenerative Diseases Research Network) and the Alzheimer's Society. Findings. Significant themes, for carers, which emerged from the workshop were related to: (1) medication usage and administration practicalities, (2) communication barriers and facilitators, (3) bearing and sharing responsibility and (4) weighing up medication risks and benefits. These can form the basis for more in-depth qualitative research involving a broader, more diverse sample. Discussion. The supported discussion enabled carer voices and perspectives to be expressed and to be linked to the process of identifying problems in medications management as directly experienced by carers. This was used to inform an agenda for research proposals which would be meaningful for carers and people with dementia. © 2014 Poland et al.; licensee BioMed Central Ltd.

The New Software Package for Dynamic Hierarchical Clustering for Circles Types of Shapes

In data mining, efforts have focused on finding methods for efficient and effective cluster analysis in large databases. Active themes of research focus on the scalability of clustering methods, the effectiveness of methods for clustering complex shapes and types of data, high-dimensional clustering techniques, and methods for clustering mixed numerical and categorical data in large databases. One of the most accuracy approach based on dynamic modeling of cluster similarity is called Chameleon. In this paper we present a modified hierarchical clustering algorithm that used the main idea of Chameleon and the effectiveness of suggested approach will be demonstrated by the experimental results.

Kiemelt gazdálkodástani kutatások a Public-Private Partnership területén – összehasonlító elemzés = Selected publications on Public-Private Partnership from a business studies perspective – comparative analysis

A tanulmányban összefoglalóan bemutatom a Public_Private Partnership (PPP) gazdálkodástani szempontból releváns kutatói munkáinak fogalomhasználatát, kérdésfeltevéseit, illetve főbb eredményeit. Ezzel betekintést kívánok nyújtani abba, hogy mit kutatnak a PPP területén a kollégák gazdálkodástani szempontból. Láthatóvá szeretném tenni, hogy eszerint melyek a „jelentős” témák és kérdések a tudományos közösség mai felfogása alapján. Az elemzés középpontjában huszonhárom, a Public-Private Partnership gazdálkodástani megközelítéséhez kapcsolódó, konkrét tudományos kutatásra épülő irodalom áll, amelyek láthatóvá teszik a PPP sokféle értelmezését a szerzők által alkalmazott részben eltérő definíciókkal. A többféle szempontból végzett szisztematikus elemzés eredményeképpen látható, hogy noha az írások mondanivalójuk függvényében vagy kiemelik a PPP partneri, kockázatmegosztó jellegét, vagy ezt nem hangsúlyozzák és általánosabb értelmezéssel dolgoznak. A PPP-t leginkább kritikusan bíráló szerzők körében jellemző, hogy a gyakorlati megvalósulás alapján a PPP-nek inkább feladatátadó, semmint partneri, illetve inkább finanszírozási, semmint értéknövelő jellegét hangsúlyozzák. = This working paper summarizes the terminology, research focus and primary results of academic articles on Public-Private Partnership (PPP) from a business studies approach. This is to show what fellow researchers focus on. I mean to highlight the „significant” topics as per the current understanding of the academic community. The analysis focuses on twenty-three academic articles that reveal the various interpretations of PPP, using somewhat different definitions. Analytical results show that the articles do not use a common interpretation, but authors either highlight the partnership, i.e. risk sharing nature of PPP; or it is not emphasized, and they use a more general interpretation instead. Researchers most critical with PPP typically give importance to the outsourcing and financing aspects of PPP in practice, rather than its partnership or value increasing character.

Costs and Benefits of Stem Cell Research and Treatment: Media Presentation and Audience Understanding in Hungary

This study examined the press coverage and audience understanding of the costs and benefits of stem cell research/treatment in Hungary. A content analysis of five newspapers and a focus group study was conducted. The way participants talked about the costs and benefits in many aspects echoed the dominant framing of the issue in the press (medical benefits = main benefit, high expense of treatment = dominant negative aspect). Even though participants applied analogical reasoning to formulate some risks that were missing from the reporting on stem cells, many gaps of the media coverage were echoed in gaps in lay discussions.

Measuring Organisational Innovation – The Example of the European Community Innovation Survey (CIS)

In the last decade, non-technological and particularly organisational innovations have gained more and more importance and research focus. However, there is no consensus among the academic community either about the definition or about the broader theoretical and methodological foundations of this phenomena. In the present study the authors intend to partly improve this knowledge deficiency syndrome by analysing the most important theoretical contributions of organisational innovation and by reviewing the development in the methodological tools aimed to measure organisational innovation on a European level. By doing so, the authors will focus on the various waves of the Community Innovation Survey (CIS) as an employer-oriented and of the European Working Conditions Survey (EWCS) as an employee-oriented survey. Finally, they will formulate some remarks for further empirical research streams.
