Accessibility measure for haemophilia patients: Study of anti-haemophilic factors availability in the Rhône-Alpes County, France

Abstract Accessibility measures are useful for studies in Economic Geography. For example, accessibility to potential customers can be used in a study of firm behaviour. In such a study, it would be relevant to consider where potential customers live. This can be accomplished by splitting the accessibility measure into three parts: accessibility within the municipality, in other municipalities within the functional region, and in other regions. Many studies have proved this to be a very useful way to incorporate the spatial structure of the economy into economic studies. This paper deals with the issue of finding the distance-friction parameters needed to calculate such accessibility measures. There is a particular distance-friction parameter for interaction within the municipality, between municipalities within the functional region, and between regions. One way to find the distance-friction parameters is to solve a constrained gravity model, in which the functional regions are used as constraints. Both the models and the optimisation procedures in matrix form, and the Matlab programs used in the research are presented. The spatial constraints are gradually introduced into the models, which empowers the researcher to make such adjustments on their own. The data set used is available for downloading, and the reader can then try the models before creating a data set of their own.

Accessibility Measure

Time is considered as an important element for rural inhabitants to access different essential activities efficiently. A time-space prism is a tool through which inaccessibility problems of the rural population can be resolved. Hence, the motive of this research is to examine the travel patterns, and to develop a time-space prism for the local population of the study area. The time-space prism was developed from the data, which were collected from the sampled households with the help of a questionnaire survey. This research found that transportation facilities in rural sub-regions could reduce the travel time of people, which could enhance their capability of accessing routine activities within the available time. The accessibility standards can be improved in this way, which can put the positive impacts on the sub-regional economy.

Accessibility Measure

Since accessibility is an essential factor in land-use and transport planning, several methods have been developed to evaluate it. Nevertheless, it has seldom been an essential part of performance measures for policy evaluation from the viewpoint of individuals' quality of life (QoL). The objective of this study is to develop an integrated evaluation method of accessibility, QoL, and social interaction which contributes to the evaluation of land-use and transport policies for livable and sustainable urban development. In this paper, based on quantification of the weights of multielements of QoL, we develop a QoL-based accessibility measure and a QoL performance measure to address appropriate policies of land-use transport coordination and integration by disentangling the mismatch between real urban structures and people's demand for QoL. Furthermore, we explore embryonic ideas for the development of a generalised framework of QoL evaluation, incorporating social interactions and institutional design which link the QoL concept with quality of space and quality of procedure.

Accessibility Measure

We analyze the impact of different accessibility measures on the interpretation of associated equity analysis using the Gini coefficient and the (pseudo) Palma ratio, and the impact of the method of assigning zonal accessibility on Gini estimation results using four different alternatives. Two types of potential accessibility measures (zonal and person-based) and two ratios of potential jobs to potential population (intra-modal and multi-modal) are estimated for car and transit in the Netherlands' Randstad region, Greater London, and São Paulo relying on network data, schedule-based data, and speed profiles. Gini results are heavily influenced by the accessibility indicator and the method of assignment. The Palma ratio is also influenced by the choice of accessibility indicator, with the person-based potential accessibility measure tending to show greater inequity.

Accessibility Measure

Background and ObjectivesAnxiety buffer disruption theory (ABDT) is an application of terror management theory to posttraumatic stress disorder (PTSD). ABDT predicts that posttraumatic stress reactions occur when buffers of awareness of death, such as meaning in life, self-esteem, and social intimacy, fail to suppress overwhelming death-anxiety. In this study, we hypothesized that generativity may also serve as an effective buffer of awareness of death and PTSD. Design The present study investigated the presence of anxiety buffering disruption in first responders with a spectrum of posttraumatic stress via a mediation path model of self-report measures of PTSD symptoms, anxiety buffer variables, and death-though accessibility. MethodsTo investigate the role of anxiety buffering in PTSD, a sample of 986 first responders completed self-report measures of PTSD symptoms and anxiety buffer variables in randomized order, and a death-thought accessibility measure following random assignment to mortality salience (n = 290) or control (n = 302) conditioning. Results and ConclusionWhile results indicate PTSD symptoms have a small relation to increased awareness of death, results indicate anxiety buffering variables did not mediate the relation between PTSD symptoms and awareness of death. Nonetheless, generativity and meaning in life, self-esteem, and social support were significant predictors of lower levels of PTSD.

Accessibility Measure

In Europe, the share of people aged 65 years and above is expected to increase exponentially, and in 2050, for the first time in human history, the number of older people will be larger than the number of children under the age of 15. Aging is associated with increased vulnerability and dependence on medical care services. For these reasons, providing access to health services to people aged 65 years and over is crucial. From the perspective of social equity, everyone should have the opportunity to access healthcare services equally, but due to economic and geographical issues, achieving this level of equity is challenging. The aim of this study was to fill the gap between scientific and actual practices using an accessibility measure to evaluate urban accessibility to primary healthcare services and to support decision-makers to better allocate resources in local restructuring of welfare policies. The accessibility measure was designed considering both the land use and the transportation components, the local healthcare supply system, and a multimodal transportation network. The methodology was applied to the city of Naples considering Local Health Agency (ASL) healthcare services to the elderly. The ASL is the largest health agency in Europe, consisting of 17 buildings serving nearly 200,000 elderly. The results show that the entire elderly neighborhood population suffers from poor accessibility to primary health services, especially in the city suburbs, and that the methodology could be effectively applied to urban planning strategies to achieve a high quality of life for elderly people. Due to poor dialogue between the authorities, this could help to improve the decision-making process through the lens of social equity.
