The emergency department (ED) has often been considered the safety net of the American healthcare system. It earned this distinction because every person in the United States has access to a medical screening exam and stabilization at an ED regardless of their ability to pay. Unfortunately, over the past several decades, decreasing numbers of EDs and inpatient beds, coupled with increasing rates of ED usage, has led to crowding of EDs across the country. Crowding leads to unsafe conditions that may increase morbidity and mortality for patients, or cause patients to leave the ED without being evaluated by a physician. Essentially, crowding causes a barrier for patients to access their right to emergency evaluation. The problem of crowding is most pronounced in large urban communities, and these already frequently underserved patients suffer the most from the crowding burden. The main cause of crowding seems to be the boarding of admitted patients in the ED, however many often cite high rates of non-urgent patients presenting to the ED as a cause of crowding. Some have even suggested diverting non-urgent patients to help solve the problem of crowding. I became interested in this topic due to crowding concerns and initiatives to decrease the number of patients who left without being seen at my own institution. As I reviewed relevant research, I became aware of my own misconceptions and noted a trend of literature suggesting non-urgent patients are not the cause of crowding. Drawing on research from many different sources, paired with evaluation based on principles in bioethics, I have come to several conclusions. I believe the systematic diversion of non-urgent patients is unsafe, and that the unequal burden of ED crowding on urban communities represents an unjust barrier in access to care. We must continue to carefully research the demographics of patients frequently presenting to EDs to avoid perpetuating stereotypes about which types of patients are responsible for crowding. We should also look for ways to ease the crowding burden in urban communities. Additionally, we should take a qualitative assessment of our individual communities to determine if there are any particular reasons in our community that people choose to use the ED rather than other healthcare options. I believe these suggestions can be an important addition to the efforts already in motion to help reduce ED crowding and provide equitable access to emergency medical evaluation.

Full textIn the field of human factors engineering the issue of how to present electronic text to people has been studied intensely for over 35 years. However, one major consideration that has largely been overlooked in these studies is how visual impairments affect reading of computer text. Specifically, the issue of how text can be modified to improve readability of CRTs for individuals with low vision. A 2x5x2x3 (visual capability, font size, polarity, and contrast) mixed-factor, repeated-measures experimental design was used to determine if changes in font size, contrast polarity, and/or contrast can improve reading speeds and reduce error rate for people with low vision.
The results of this experiment show that alterations in text can be made that do not affect unimpaired vision readers while dramatically improving the reading capabilities of the impaired vision population. For character size, 12 and 14 point font sizes were found to be too small for the visually impaired population examined. In general, 18 and 30 point font sizes were equal to each other and to the 24 point font size, but for some interactions these two were found to produce longer response times and higher error rates. Thus, a 24 point font size is recommended.
Unlike previous research with visually impaired participants, this experiment found that negative (white-on-black) polarity worsened reading performance. It is thought that this discrepancy is a result of polarity's interaction with small font sizes. For this reason, it is recommended that for font sizes of 18 points and below, positive polarity should be used. For 24 and 30 point sizes either polarity is satisfactory, though previous research (Legge, Pelli, Rubin, and Schleske, 1985b; NRC, 1995; Rubin and Legge, 1989) suggests negative polarity might be better for some visually impaired readers..
Contrasts of 3:1, 7:1, and 18:1 were used in this experiment and had no significant effect for either vision group. However, contrast did significantly interact with both font size and polarity. For font sizes of 18 points or below, it is recommended that contrasts of 18:1 be used for either polarity, but this is very important if negative polarity is used.
The above recommendations are based on a small group of impaired vision readers. Visual impairments vary widely and the sample used in this experiment represented only a portion of them, with respect to both cause and severity. Wherever possible, computer text should be tailored to the unique needs of its users.

Full textThis dissertation explores inequality in access to dental and vision care. It includes three chapters. The first chapter examines the impact of vision coverage on vision health and vision care utilizations using nationally representative Behavioral Risk Factor Surveillance System (BRFSS) data. It also examines the trend in cost/insurance barrier to access vision care. I found significant evidence suggesting positive relationship between vision insurance and vision care utilization. This finding confirms the findings of previous studies on the same topic. Examining the cost/insurance barrier to access vision care, I have found evidence suggesting increase in the barrier to access vision care in recent years.
The second chapter analyzes the effect of the early Medicaid expansion under the Affordable Care Act (ACA) on dental care utilization among U.S. adults using nationally representative BRFSS survey data for the years 2006 to 2012. Childless adults, who were not eligible to be covered in Medicaid before the implementation of the ACA except through 1115 waiver or state/locally funded programs, were made eligible for mainstream Medicaid through the ACA. In this chapter, I examine whether the early implementation of the Medicaid eligibility expansion to childless adults during 2010-2012, gave rise to increase in dental care utilization of this group. Using differences-in-differences model for the analysis, I find no significant evidence of changes in dental care utilization of childless adults in the post expansion period. Also, I find evidence of no (very small) significant change in dental care utilization of childless adults compared to parents in the post eligibility expansion period as Medicaid payment to dentist’s increase.
The third chapter analyzes income related inequality and inequity in dental care utilization among adults in New York state using data from the BRFSS survey. To my knowledge, this is the first paper which tries to estimate income related inequality in adult dental care utilization in New York state. I improve on existing inequality literature by using multiple imputation to deal with the problem of calculating income inequality using interval-censored and top-coded income data. This paper calculates inequality using the corrected concentration index proposed by Erreygers which has not been commonly used in previous literature to estimate inequality in dental care utilization. In decomposition of inequality, I allow for heterogeneity in the utilization with respect to need using the procedure proposed by Van de Poel, Van Doorslaer and O’Donnell (2012) and thereby allow for violation of the assumption of vertical equity which is an implicit assumption in decomposition of inequality in previous literature analyzing inequality in dental care. I find evidence of pro-rich inequality and inequity in dental care utilization. The findings suggest that conventional horizontal inequity index overestimates the need-justified index of inequity for the state of New York.

Full textThis research work is dedicated to the development of an autonomous navigation strategy which includes generating an optimal trajectory with obstacles avoiding capabilities, detecting specific object of interest (i.e. a window) and then conducting the subsequent maneuver to approach the window and finally access into the building. The vehicle is navigated by a vision system and a combination of inertial and altitude sensors, which achieve a relative localization of the quad-rotor with respect to its surrounding environment. A MPC-based path planning method using the information provided by the GPS and the visual sensor has been developed to generate an optimal real-time trajectory with collision avoidance capabilities, which starts from an initial point given by the user and guides the vehicle to achieve the final point outside the target building. With the aim of detecting and locating the object of interest, two different vision-based object detection strategies are proposed and are applied respectively in the stereo vision system and the vision system using the Kinect. After estimating the target window model, a motion estimation framework is developed to estimate the vehicle’s ego-motion from the images provided by the visual sensor. There have been two versions of the motion estimation frameworks for both vision systems. A quad-rotor experimental platform is developed. For estimating the translational dynamic of the vehicle, a Kalman filter is implemented to combine the imaging, inertial and altitude sensors. A hierarchical sensing and control system is designed to perform the navigation and control of the quad-rotor helicopter, which allows the vehicle to estimate the state without artificial marks or other external positioning systems

Full textA major finding in the scientific study of conscious perception has been the existence of two temporally-distinct phases of visual processing. The first, characterized by the feed-forward propagation of evoked activity in early visual cortex, is not typically associated with conscious perception. The second phase involves a reactivation of early sensory cortex by downstream regions and is often cited as a correlate -- if not a proximal cause -- of consciousness. This raises a few crucial questions: firstly, what causes this feedback process to emerge, and secondly, what distinguishes a stimulus representation that has undergone such feedback processing from one that has not ? At the time of writing, two competing theories have been proposed. The first theory, hitherto referred to as "early-and-local", posits that conscious access emerges from the very emergence of a feedback loop between high-level sensory cortex and its primary counterpart, and that this cortical resonance is driven entirely by upstream activations along the feed-forward chain. This implies that only those stimuli that exhibit high salience from the onset can become conscious, and by extension, that the stimulus' reportability is governed entirely by early evoked activity in primary sensory cortex. "Late-and-global" theory, by contrast, posits that conscious perception is the direct result of routing of information through a distributed cortico-cortical network called the Global Neuronal Workspace (hereafter GNW). By this account, visual information in various local cortical regions is given access to routing infrastructure by some selective process, namely attention. In 2013, Sergent and colleagues tested a prediction derived from this second model: that an arbitrary sensory representation that has initially failed to become conscious can be hooked into the GNW by means of an attentional manipulation. To do this, a low threshold target Gabor patch was presented, followed by an extrinsic cue either at the location in which the Gabor had been presented, or on the opposite side of the screen. Subjects were better at discriminating the orientation of the Gabor in trials where the cue had been presented on the same side as the target, and also reported seeing the target more clearly, suggesting that the retrospective intervention of attention was enabling a weak signal to gain access to the global neuronal workspace. We present data from psychophysical modeling and functional magnetic resonance imaging that point to a causal role for attention in the emergence of a conscious percept, with implications for the structure of perceptual representations in early sensory cortex

Full textPurpose: To examine if disparities exist among US adults aged 40 and above that reported reasons for no access to eye care.
Methods: A secondary analysis was conducted on 14,129 US adults aged 40 and above who responded to the Vision Module of the 2007 BRFSS using cross-tabulations, logistic regression and chi square statistics.
Results: Respondents reporting cost/insurance as the main reason for not accessing an eye doctor was greater among adults with education level < HS than with > HS (p<0.001). The percentage who reported cost/insurance as the main reason was greater among adults with income < $25,000 than with >$50,000 (p<0.001). Similarly, a greater percentage of Black adults reported cost/insurance as the reason for not accessing an eye doctor compared to White adults.
Conclusion: Given that Cost/Insurance was the most frequently cited reason, making eye health/health insurance available to most or all Americans will go a long way in narrowing the gap in vision health disparities.
Kufa, Erica. "The timing of first antenatal care visit and factors associated with access to care among antenatal care attendees at Chitungwiza municipal clinics, Zimbabwe." Thesis, University of the Western Cape, 2012. http://hdl.handle.net/11394/4553.
Full textBackground and Rationale: Antenatal care (ANC) is vital for accessing prevention of mother to child transmission (PMTCT) services. The timing of the first ANC visit is critical for HIV infected pregnant women to access antiretroviral (ARV) prophylaxis as recommended. In addition pregnant women access other interventions like syphilis screening and treatment, provision of ferrous iron supplements, malaria prevention and treatment, health education, identification and management of risk factors. There is however paucity of information on factors associated with the timing and adequate use of ANC services in Chitungwiza Township, Zimbabwe. Aim: This study aimed to determine the factors associated with early access to and adequate use of ANC services among women attending ANC in the four polyclinics in Chitungwiza Township.Method:The study included a retrospective record review of women who registered for ANC in 2010 and a cross sectional study of pregnant women attending ANC clinic for the first time during the current pregnancy during the survey period. Data on gestation age at first ANC visit, number of ANC visits, age, gravidity, parity, tetanus, iron sulphate, rhesus results, HIV test result, WHO clinical stage, CD4 count, cotrimoxazole, PMTCT option accepted, date of initiation of AZT or ART; partner HIV test results; and infant feeding adherence done was abstracted into an MS Excel spreadsheet from the 2010 ANC registers in the four primary health care clinics. Every fourth record was captured. Exit interviews were also conducted on all women attending ANC for the first time during the current pregnancy using a structured questionnaire. Questions on socio-economic status, pregnancy history, reasons for seeking ANC, knowledge and belief about ANC services and their perception of the service received were asked. The outcome variables were gestation age at first ANC visit and the number of ANC visits. The spreadsheet was imported into Epi Info 7.0.9.7 and STATA 11 for analysis. The questionnaires were captured into an Epi Info 7 database exported to STATA 11 for analysis. A sample of 1,236 of first ANC visit records were abstracted from the 2010 ANC registers in the four primary care clinics and 80 women coming for ANC were interviewed in three clinics. The prevalence of pregnant women attending ANC for the first time at gestation age less or equal to 14 weeks and the prevalence of women with less than 4 ANC visits were computed. Pearson Chi-square tests were used to determine the strength of the relationships between the dependent variable (gestation age at the time of the first visit) and independent variables of age, marital status, level of education, parity, gravidity. All statistical tests were performed at 5% significance level and estimates were calculated at 95% confidence interval. Multiple logistic regression analysis was used to investigate the association between the outcome and the independent variables. Model interpretation was done using odds ratios (OR). Levels of knowledge and perception about ANC services as well as service content during the visit were also summarized. Results: Less than 1% of the women who attended ANC in 2010 came for 1st visit at week 14 or less, while of the women interviewed, 2.5% came at similar gestation age. Thirty-nine percent of women attending ANC in 2010 had at least four visits. Lower parity and tetanus immunization were significantly associated with early ANC initiation, while tetanus immunization and syphilis screening were associated with the number of visits.Among the interviewed women (n=80), 72.1% believed that a pregnant women should start ANC at 14 weeks or earlier. Most women (61.7%) cited having no money for booking as the reason for not coming earlier. Need for husband or partners permission, procrastination and not having any health problems with previous pregnancies were also a barrier to access. Uptake of HIV testing was very high at 94.7% of the women. However partner testing was very low at 2.1%. Knowledge of the appropriate time of the first ANC visit was somewhat high but not universal. Conclusions and Recommendations: Timely and adequate uptake of ANC services is very low in Chitungwiza Township. The user-fees appeared to be a major barrier to accessing ANC timely. While correct knowledge about when to go for ANC and the health problems women face during pregnancy and childbirth is prevalent,other factors like the need for permission from spouse or partner and procrastination were barriers to seeking service. Abolishing maternity fees should be seriously considered in order to increase access to timely ANC services. Sustainable means of financing services without reducing quality should be sought. There was variable uptake of various interventions in the ANC package due in part to supplies stock outs. There is need for strengthening the procurement and distribution systems so as to ensure continuous supplies at service delivery level.

In the United States, many are critical of agricultural policies and economic incentives that support large-scale food production and the dominant actors in the mainstream agrifood system. Critics point out that at the same time agribusinesses and very large-scale farmers receive support, there are those in poverty who struggle to meet their food needs. Critics question what that relationship should be between civil society and the agrifood system. A variety of activities are addressing concerns of social injustices in the system. For example, participation is increasing in civic and urban agriculture. Civic agriculture is the interrelated activities of small-scale, socially and environmentally sound practices of food production and consumption that aim to increase community sustainability. Urban agriculture is food production in and near cities. By focusing on Kansas and the Kansas City metropolitan area, this dissertation addresses the following questions: How do the relations between civil society and the U.S. agrifood system impact the level of fairness in the system? To what extent are urban agricultural activities fostering fairness in the agrifood system, including access to fresh foods, civic engagement, and fulfilling careers, while also benefiting the environmental health of the city? Survey and interview data collected by a research team on agriculture in Kansas sets the context for my examination of urban agriculture in Kansas City’s urban core. In addition to participant observations and primary and secondary data analysis, I conducted 38 semi-structured interviews with growers (27), food advocates (4), community organizers (4), and governmental employees (3). In Kansas City, many of the activities and programs in place are building community, strengthening civil society, and promoting food justice for the poor and for people of color, for example, in food deserts, which are locales where people particularly face challenges in meeting their food needs. While some participants are more focused on their immediate communities and less so on overt widespread change, others feel a part of a social movement aiming to change the agrifood system. Diverse people from various social classes and races are increasingly becoming involved in growing food and food advocacy to expand fairness in the system.

Full textThe law of the bearing July 27th, 1999 creation of the universal health coverage intervened within the framework of a general policy of fight against exclusion. In order to improve the access to the care of a growing number of poor people, the Socialists worked out a device comprising two facets. The first facet aimed at the generalization of the health insurance, by allowing the affiliation the general scheme on a subsidiary criterion of residence. The second facet had as an ambition to offer a complementary coverage health, to the million people who did not profit from it. This service being subjected to the respect of a condition of residence and a condition of resources. The whole of the device founded by law CMU replaced for the departmental medical assistance and the personal insurance. The extent of the inequalities of health, concerning initially the poorest individuals and most isolated from the society, led to general warm welcome of law CMU. However, although regarded as a great law of public health, certain measurements were the theatre of debates and oppositions, as well on the political scene as in the society. That in particular was the case concerning the effect of threshold induced by the introduction of a ceiling of resources, the risk of deresponsabilisation of the recipients having access free to the device, rules of financing primarily based on public taxes and contributions, the choice of a partnership management between social security and private partners with in particular the organizations of complementary health, or concerning the reserve of a minority of health professionals with regard to the device leading to refusal of care

Full textENGLISH ABSTRACT: In percutaneous procedures, where the surgeon inserts a needle into a target in the patient, it is challenging to access the target at the rst attempt. Repeated needle insertion attempts are highly undesirable, as they lead to increased theatre time, patient haemorrhage and radiation exposure. The proposal of this thesis was to develop a low-cost system to aid surgeons with the process of positioning and orientating the needle prior to insertion. The proposed system uses a stereo pair of images produced by a standard C-arm uoroscope. By applying computer vision techniques, such as triangulation, the desired needle position and orientation are determined from the set of images. An articulated manipulator is used to position and orientate the needle. The surgeon makes selections on the images, via a graphical user interface (GUI), to indicate the desired position and orientation of the needle. Following these selections, an algorithm determines the necessary angles for the manipulator. The surgeon then positions the manipulator accordingly. Results from tests on a phantom showed the system to be repeatable and accurate to 2 mm. This is less accurate than similar, existing systems which, reported accuracies of 0:25 and 1:21 mm. However, 2 mm accuracy is considered adequate as it allows a range of percutaneous procedures to be performed such as needle biopsy, regional anaesthesia, brachytherapy and percutaneous nephrolithotomy (PCNL). Tests on both a phantom kidney and a porcine kidney indicated that the system can function in a real percutaneous procedure and with an anatomical target. The total cost to develop the prototype system was R15 000. The accuracy of the proposed system and the time to gain access to the target indicate that the system can be a bene cial aid to surgeons when performing percutaneous procedures. As minimal X-ray imaging is required, patients will also be spared excessive radiation exposure and theatre time.
AFRIKAANSE OPSOMMING: In perkutane prosedures, waar die chirurg 'n naald in 'n teiken op die pasiënt invoeg, is dit moeilik om met die eerste probeerslag toegang tot die teiken te bekom. Herhaalde pogings om die naald in te voeg is hoogs ongewens, aangesien dit tot verlengde teatertyd, bloeding by pasinte sowel as stralingsblootstelling lei. 'n Laekostestelsel is ontwikkel om chirurge by te staan met die proses om die naald voor invoeging te plaas en te oriënteer. Die stelsel gebruik 'n paar stereobeelde wat deur 'n standaard-C-arm- uoroskoop voortgebring word. Met behulp van rekenaarsigtegnieke, soos triangulasie, word die gewenste naaldposisie en -oriëntasie uit die stel beelde bepaal. 'n Geartikuleerde manipuleerder word gebruik om die naald te plaas en te oriënteer. Die chirurg voer die vereiste invoerdata deur middel van 'n gra ese gebruikerskoppelvlak (GGK) in, waarna 'n algoritme die vereiste hoeke vir die manipuleerder bepaal. Die chirurg plaas dan die manipuleerder dienooreenkomstig. Die resultate van toetse op 'n fantoom toon dat die stelsel herhaalbaar en tot op 2 mm akkuraat is. Dit is minder akkuraat as soortgelyke, bestaande stelsels, wat 'n akkuraatheid van 0:25 mm en 1:21 mm onderskeidelik aangemeld het. Tog kan akkuraatheid van 2 mm as voldoende beskou word, aangesien dit 'n verskeidenheid perkutane prosedures moontlik maak, soos naaldbiopsies, regionale anestesie, bragiterapie en perkutane nefrolitotomie (PCNL). Toetse op 'n fantoomnier dui daarop dat die stelsel wél in 'n werklike perkutane prosedure kan funksioneer. Toetse op 'n varknier toon dat die stelsel wél ook met 'n anatomiese teiken kan werk. Die totale koste om die prototipe te ontwikkel was R15 000. Die akkuraatheid van die voorgestelde stelsel en die tydsduur om toegang tot die teiken te bekom, dui daarop dat die stelsel 'n nuttige hulpmiddel kan wees vir chirurge wat perkutane prosedures uitvoer. Aangesien minimale Xstraalbeelding vereis word, sal dit pasiënte ook oormatige stralingsblootstelling en verlengde teatertyd spaar.

El modelo de negocios es realizado con la metodología Canvas, y posteriormente analizado utilizando herramientas como 5 Fuerzas de Porter, PESTEL y FODA; de manera de proponer estrategias para una organización exitosa. La metodología concluye con el análisis económico y las conclusiones que dan cuenta de su viabilidad. Formando Futuro contempla la creación de una red de jardines infantiles orientado a generar igualdad de oportunidades al acceso a una educación de calidad que además no seleccione a su alumnado y promueva la movilidad social mediante la equiparación de competencias. La propuesta de valor se basa en entregar un servicio de educación preescolar para niños entre 2 y 6 años, asegurando estándares de cuidado y enseñanza exigidas por la JUNJI, y sumado a ello, ampliando la propuesta a la incorporación de metodologías y mejores prácticas a internacional adaptadas a la realidad local. Inspirados en el benchmark internacional, se definen los pilares fundamentales del proyecto educativo: el valor del individuo, la cooperación y el aprendizaje por medio de la acción. El proyecto fue evaluado para tres (3) establecimientos para un horizonte de evaluación de 15 años, con una tasa social de descuento de 6%. El valor presente neto es de 962 millones de pesos, con una tasa interna de retorno de un 18, con lo que el proyecto es atractivo para inversionistas que estén evaluando ser benefactores de iniciativas sociales. Sin embargo, la nueva normativa que prohíbe el lucro en la educación incrementa las exigencias para los sostenedores de los establecimientos lo que a su vez ha provocado un desincentivo para llevar a cabo este tipo de iniciativas. Sin perjuicio de lo anterior, un proyecto como éste genera muchas externalidades positivas motivan a organizaciones sin fines de lucro, corporaciones religiosas o municipalidades a invertir; como por ejemplo: el aumento de cobertura y calidad educacional, el apoyo a la inserción laboral femenina, la creación de nuevas fuentes laborales, la capacitación familiar y social en temas relacionados con educación infantil, posibles proyectos con la comunidad, etc.

Full textLike the rest of the society modern health care has to deal with the ever increasing information flow. Imaging modalities such as CT, MRI, US, SPECT and PET just keep producing more and more data. Especially CT and MRI and their 3D image stacks cause problems in terms of how to effectively handle these data sets. Usually a PACS is used to manage the information flow. Since a PACS often is implemented with a server-client setup, the management of these large data sets requires an efficient representation of medical image stacks that minimizes the amount of data transmitted between server and client and that efficiently supports the workflow of a practitioner.
In this thesis an efficient wavelet representation for large medical image stacks is proposed for the use in a PACS. The representation supports features such as lossless viewing, random access, ROI-viewing, scalable resolution, thick slab viewing and progressive transmission. All of these features are believed to be essential to form an efficient tool for navigation and reconstruction of an image stack.
The proposed wavelet representation has also been implemented and found to be better in terms of memory allocation and amount of data transmitted between server and client when compared to prior solutions. Performance tests of the implementation has also shown the proposed wavelet representation to have a good computational performance.

Full textThis PhD dissertation focuses on the ways and means of the museum experience for visitors with visual or hearing deficiencies. For that matter, the aim is to grasp both the cultural mediation systems, the welcoming apparatus proposed by museums but also the experience lived by the visitors. This allows to touch upon the discourses then carried out regarding accessibility and difference. A field work was carried out in the museums of the region Île-de-France and through interviews with people with disabilities. The main objective was to bring out the way in which museums, through the devices they propose and by the discourses they carry and relay on accessibility, organize and reveal at the same time the social treatment of disability. Museums can be considered frameworks for analysis and for understanding identity trajectories, since the social processes giving a place and an identity to people are strongly perceptible in this institution. Moreover, the sensitive connection to environment and, in this case to the exhibits, is also conditioned by the museum. It therefore contributes to establish a self-image for the visitor, and thus to structure the visitor's journey. In addition, by also highlighting the ability of individuals to seize these elements to develop their identity trajectories, this work highlights the responsibility of the museum as an institution, which participates in the construction of social and personal identities

Full textThe thesis investigates research data, as there is a growing demand for opening them. Research data are information that is collected by scientists in order to be used as evidence for theories. It is a complex, contextual notion. Since the 2000s, open access to scientific data has become a strategic axis of research policies. These policies has been relayed by third actors, who developed services dedicated to support researchers with data management and sharing.The thesis questions the relationship between the ideology of openness and the research practices. Which kinds of data management and sharing practices already exist in research communities? What drives them? Do scientists rely on research data services? Fifty-seven interviews were conducted with researchers from the University of Strasbourg in many disciplines. The survey identifies a myriad of different data management and sharing practices. It appears that data sharing is embedded in the researcher’s strategy: his main goal is to protect his professional interests. Thus, research data are part of a credibility cycle, in which they get both use value (for new publications) and exchange value (as they are traded for other valuable resources). The survey also shows that researchers rarely use the services developed in a context of openness. Two explanations can be put forward. (1) The service offer comes too early to reach researchers’ needs. Currently, data management and sharing are not within researchers’ priorities. The priority is publishing, which is defined as source of reward and recognition of the scientific activities. (2) Data management services are offered by actors outside the research communities. But scientists seem to be more influenced by internal networks, close to their research topics (like journals, infrastructures…). These results prompt us to reconsider the mediation between scientific communities and open research data policies

Full textThe powers and enforcement methods used by the french economic control authorities constantly changed since the beginning of the 00s. In many aspects, these new prerogatives and approach have raised concern, as the amount of sanctions imposed to the operators exploded. One of the problems relies in the fact that, willing to foster a quicker and more effective public action, the legislator accepted to give more autonomy to the authorities, especially vis a vis the courts and judges. Thus facilitating the concentration of powers in the sole hands of the control authorities, which in many branches of economical regulation, are now able both to prosecute and impose penalties. However, since 1992, a growing array of fundamental rights have been attributed to the economic operators as legal persons, especially the right to have a fair trial, and to have access to legal recourse. The aim of our research, is to determine how the equilibrium between the law enforcement and the respect of this fundamental rights could be improved. After analysing the different hard spots in the procedures of the french authorities regarding fundamental rights, several solutions are proposed, classified in two categories: Upstream, the measures that could be taken to improve the legal security of economic operators in France ; The more targeted measures to be taken regarding the major hard spots in the authorities powers and procedures

This study investigated the influences on visit access design in terms of visitor behavior, museum display space and access-affecting exhibition design through literature review to understand factors affecting visit access design and case study with survey and site observation to assess the influences on the design of visit access in the display spaces of the case. Results indicated that 56.5% of visitors were lost in the visit; the difference between visitor attribute and characteristics and visit access is insignificant; the values of influence in ascending order in the regressive analysis of display design elements are “showroom and floor layout correlations”, “production and placement of access signs”, “lighting design and layout”, and “location of text description”; where the “coordination between guiding vision and special display contents” and visit access satisfaction are negatively correlated. The possible reason for this construct is that most visitors visit a show randomly, though this visitor behavior is correlated with the museum’s spatial arrangement. Also, the influence of “DM” (tour map) and “monument/artwork placement and display manner” on visit access is insignificant. This study primarily investigated the suitability of the design elements of display spaces in museums in terms of visit access design and planning, hoping to provide a reference for display space planners of museums and so to ensure both designers and visitors can enjoy a successful and effective exhibition.

Museums are social educational institutions that promote public welfare and also the places for storing memorial objects. To cope with problems stemming from population aging and increasing prevalence of dementia, many foreign museums have launched access programs for visitors with dementia. Utilizing collections and rich educational resources, these museums work with professional organizations in providing services such as reminiscence therapy, art tour, and social interactions to visitors with dementia and their care partners. This study first reviewed related literature to investigate the implementation methods, strategies, and characteristics of museum access programs in United States and United Kingdom. Later, using “Meet Me at MoMA”, an access program created by Museum of Modern Art in New York, and “A Tour of Taiwan History” launched by National Museum of Taiwan History for patients with Alzheimer's disease as examples, this study analyzed the implementation methods, required supportive systems, current implementation statuses, problems encountered, and effectiveness of these two programs. Besides, the opinions of directors of these programs and related professional organizations were collected through interview. This study attempted to integrate domestic and foreign experiences and provide substantive suggestions to museums. Results showed that museums can make use of their spatial characteristics, diverse collections, and interpretive media to develop access programs for visitors with dementia. The access programs will have positive effects on the living quality and emotions of visitors with dementia and their care partners. For museums, developing substantive support policies, implementing professional training, integrating internal resources, and seeking external cooperation are keys to developing this kind of activities. When designing activities for elderly patients and patients with dementia, they should take into account the fitness of participants and develop diverse and inclusive courses. In the present, local museums do not have as abundant internal and external resources as foreign museums. Therefore, developing a resource sharing mechanism and promoting cross-department cooperation may be the directions for the authority concerned when providing assistance to museums.

Full textRESUMO - Enquadramento: A deficiência visual é um importante problema de saúde pública que afeta 252,2 milhões de pessoas no mundo. Em 2015 existiam globalmente 36 milhões de pessoas cegas e 216,6 milhões de pessoas com deficiência visual severa a moderada. Dado o envelhecimento da população estima-se que o número de pessoas com deficiência visual irá aumentar dramaticamente provocando uma maior carga de doença e um maior impacto económico no futuro. Objetivos: Com a realização desta tese pretendeu-se investigar e caracterizar o impacto da deficiência visual em aspetos selecionados do sistema de saúde e da sociedade. Para alcançar este objetivo foram desenvolvidos cinco artigos de investigação. Considerou-se que três artigos constituíam a componente principal do trabalho realizado investigando: 1) O acesso de doentes com doenças da retina a um novo tratamento com anti-VEGF; 2) A utilização de cuidados informais em pessoas com deficiência visual e os fatores associados a essa utilização; 3) Perdas de produtividade e os seus determinantes em pessoas com deficiência visual. Foram ainda desenvolvidos mais dois artigos complementares que pretendiam: 4) Investigar medidas de resultados auto-reportadas utilizando um questionário específico para a deficiência visual (activity inventory) e um questionário genérico (EQ5D);5) Investigar o perfil dos indivíduos que aceitaram participaram nas entrevistas realizadas no âmbito dos estudos apresentados nos artigos principais. Metodologia: Foram utilizadas duas bases de dados. A base de dados nacional de morbilidade hospitalar foi utilizada para investigar o acesso a tratamentos com anti-VEGF. Dados do estudo sobre a Prevalência e custos da baixa visão em Portugal foram utilizados para os artigos referentes aos cuidados informais, perdas de produtividade, análise de medidas auto-reportadas e análise do perfil dos entrevistados. Utilizaram-se diferentes estratégias para selecionar os casos e para a recolha de informação. Utilizou-se estatística descritiva para sintetizar a informação sociodemográfica e clínica. Utilizou-se testes de chi-quadrado para comparar a composição de grupos. Utilizou-se testes T para comparar variáveis com distribuição normal e testes não-paramétricos nomeadamente teste de Mann-Whitney e teste de Kruskal-Wallis para comparar grupos. Para analisar os determinantes associados à difusão dos tratamentos anti-VEGF recorreu-se a modelos lineares generalizados. Utilizou-se modelos de regressão logística para investigar fatores associados à utilização de cuidados informais e às perdas de produtividade. Recorreu-se a modelos de regressão linear para determinar fatores associados à intensidade de utilização de cuidados informais. xii Resultados: Verificou-se que a difusão e consequentemente o acesso a um novo tratamento ocular foi significativo, distribuído de forma desigual e associado à disponibilidade de prestadores de cuidados de saúde. O número reduzido de tratamentos encontrado em alguns concelhos é problemático na medida em que pode conduzir a um aumento do número de indivíduos com deficiência visual por causas tratáveis. Verificou-se também que a deficiência visual tem repercussões significativas a nível socioeconómico dado que afeta o nível de autonomia dos indivíduos que está por sua vez associado à necessidade de cuidados informais. Afeta também a participação dos indivíduos na sociedade, afetando, a situação no mercado de trabalho e a qualidade de vida produzindo perdas de produtividades avultadas. Conclusão: A deficiência visual em Portugal produz um impacto diverso e significativo. Muitas das causas de perda de visão podem ser preveníeis ou tratadas através da tecnologia existente. Os cuidados de saúde oculares dispõem de um conjunto de intervenções de saúde baseadas na evidência, custo-efetivas e de baixo risco pelo que a medida mais importante a tomar é a de garantir que estas intervenções estão disponíveis e alcançam todas as pessoas que delas podem beneficiar.

The two fast developing industries, mobile communication and the internet, will converge in the 21st century. It is already a reality that user is able to surf the internet or view their emails and messages directly through their mobile devices, and the 3G mobile phone will soon fulfill the dream of "Internet in the pocket". The purpose of this paper, while using Roger''s Innovation Adoption Theory as its frame, is to identify the acceptance of the 3G mobile phone based on consumers'' preference and their demand for broad band. In addition, we try to find out whether the mobile phone consumers can be segregated by their life style so as to identify target consumer groups and to provide our research results to the industry to formulate their marketing strategies. The samples we used for this study are the attendants of the 2000 Taipei Communication Exhibits. From the samples we discovered that potential users can be effectively segregated by life style and Group 2 and 4 have the highest acceptance rate, though difference do exist in terms of marketing, servicing, brand, appearance and expendability. In order to target these potential customers, different marketing strategies are required. About 70% of the sample attendants who has heard of 3G mobile phone have expressed that the new generation mobile phone can provide multifunctional services when compared to WAP and GPRS phones. Primary sources of such 3G mobile phone information comes from TV, newspapers and magazines, the rest are from internet and telecommunication industry. Majority of the sample attendants showed strong interests in this new generation mobile phone and have expressed their intention to purchase the phone within a 6 to 12 month period. Between those who accept the 3G mobile phone and those who don''t, there is a clear variance on the convenience, the expandability and the appearance.
