DIAGNOSIS-RELATED GROUP ANALYSIS AND STRATEGIC HEALTHCARE BUDGETING
2011
The term Diagnosis-Related Group DRG) refers to a classification system used to assess hospital services with the aim of streamling health care costs and improving performance. The DRG system focuses on the utilization of resources, and is not concerned with the specific type of care provided to the patient. This system highlights any diseconomies and eventual critical aspects of the hospital system. This article examines the variables used to correctly evaluate hospital performance based on the DRG system. These include: Average length of Stay, Average Daily Patients Load, Comparative Performance Index and Case Mix Index.
Analyzing Stakeholder Diversity in G2G Efforts: Combining Descriptive Stakeholder Theory and Dialectic Process Theory
2008
Author's version of an article published in e-Service Journal, 6 (2), 3-23. Previous research indicates that the benefits of e-government initiatives are slower to realize than initially expected. This has partly been ascribed to the particularly complex settings of e-government projects, consisting of a variety of stakeholders promoting different and often conflicting objectives. Yet few studies have explicitly addressed the inherent challenges of this diversity. This study presents an analytical approach for investigating contradictory stakeholder interests by combining descriptive stakeholder theory and dialectic process theory. Descriptive stakeholder theory is concerned with why some s…
Las representaciones del saber académico: Aportaciones desde la Geografía Escolar
2019
When we talk with basic education´s teachers there is an impression in the case of learning Social Sciences, and Geography in particular that these sciences are not useful for the explanation of socio-environmental and daily problems. In this research, improvement proposals are sought so that students are motivated to learn about these problems. Based on two case studies such as flood risks (and their relationship with climate change) and the problems of the rural areas, the possibilities of combining motivation for learning close to personal emotions and with their own rigor have been explored of the conceptual explanation. To validate these results, quantitative and qualitative research t…
Pattern formation in clouds via Turing instabilities
2020
Pattern formation in clouds is a well-known feature, which can be observed almost every day. However, the guiding processes for structure formation are mostly unknown, and also theoretical investigations of cloud patterns are quite rare. From many scientific disciplines the occurrence of patterns in non-equilibrium systems due to Turing instabilities is known, i.e. unstable modes grow and form spatial structures. In this study we investigate a generic cloud model for the possibility of Turing instabilities. For this purpose, the model is extended by diffusion terms. We can show that for some cloud models, i.e special cases of the generic model, no Turing instabilities are possible. However,…
Why Don't We Do What We Want? Non-Consumers and the Public Dilemma in Cultural Promotion
2005
We deal with tastes and preferences, revising the linkages between both in order to analyse the special case where we express preferences to goods that do not appeal to us. We deduce the concept of a deconstructed demand and define two types of goods (embarrassing and reputable). With the help of this structure we build a demand function for cultural promotion, where the non-market-expressed non-consumers' preferences are the basis of the demand for cultural policies. Finally, in this framework the State faces a dilemma that could be solved in different ways.
Juvenile nasopharyngeal angiofibroma with orbital extension
2015
Abstract Clinical case The case of a 21-year-old male with a history of left proptosis and diplopia of two weeks of onset is presented. The MRI showed an ethmoid-orbital vascular lesion with anterior skull base invasion and orbital extension. Biopsy of the ethmoid confirmed fibrovascular tissue, which supported the diagnosis of angiofibroma. Discussion It is a benign neoplasm with local characteristics of malignancy due to its ability to invade adjacent areas. In this case, the debut presented with manifestations of orbital extension. A broad and multidisciplinary approach is needed in order to improve prognosis.
Spontaneous Meckel's cave hematoma: A rare cause of trigeminal neuralgia
2015
Background: The most common etiology of classic trigeminal neuralgia (TN) is vascular compression. However, other causes must be considered. Among these, spontaneous hematoma of the Meckel′s cave (MC) causing symptomatic TN is very rare. Case Description: We present the case of a 60-year-old woman with a 2-month history of left TN and diplopia. Neuroradiological examinations revealed a well-defined hematoma in the left MC. The patient underwent surgical decompression with a progressive neurological improvement. Conclusion: Despite the number of lesions potentially affecting the MC, spontaneous hemorrhage is rare but should be taken into account in the differential diagnosis.
Varieties of Codes and Kraft Inequality
2007
Decipherability conditions for codes are investigated by using the approach of Guzman, who introduced in [7] the notion of variety of codes and established a connection between classes of codes and varieties of monoids. The class of Uniquely Decipherable (UD) codes is a special case of variety of codes, corresponding to the variety of all monoids. It is well known that the Kraft inequality is a necessary condition for UD codes, but it is not sufficient, in the sense that there exist codes that are not UD and that satisfy the Kraft inequality. The main result of the present paper states that, given a variety V of codes, if all the elements of V satisfy the Kraft inequality, then V is the var…

Cluster sets and quasiconformal mappings
2010
Certain classical results on cluster sets and boundary cluster sets of analytic functions, due to Iversen, Lindelof, Noshiro, Tsuji, Ohtsuka, Pommerenke, Carmona, Cufi and others, are extended to n-dimensional quasiconformal mappings. Unlike what is usually the case in the context of analytic functions, our considerations are not restricted to mappings of a disk or ball only. It is shown, for instance, that quasiconformal cluster sets and boundary cluster sets, taken at a non-isolated boundary point of an arbitrary domain, coincide. More refined versions are established in the special case where the domain is the open unit ball. These include cluster set considerations of the induced radial…
