Free entry in infrastructure

With a policy of free entry, individuals, firms, or community groups who wish to supply power, water, and sanitation services can do so with minimal legal restrictions. Free entry is the opposite of"exclusivity"or"legal monopoly". Free entry is allowed in most industries, but governments usually allow only one provider of power, water, and sanitation in any given area. This is supposed to prevent wasteful duplication and ensure a supply of essential services to poor and marginal areas. But monopoly water and power utilities often operate at high cost, lack funds to invest, and provide low-quality, unreliable service. Worse, poor and marginal areas are often unserved. When the monopoly model doesn't work, it is time to look at alternatives. The authors provide examples of alternative solutions in developing countries: *In Karachi, Pakistan, the Orangi Pilot Project provides sanitation in an unplanned settlement. Roughly 800,000 working class people lived in an area where sanitary conditions were medievaland a long-hoped-for sewerage system never came. Starting in 1980, a charitable group developed a low-cost approach to piped sanitation, explained the technology to the community, and catalyzed community action. Householders and neighborhoods funded the construction of household pourflush latrines and sewerage lines. * In Paraguay, 300 to 400 private individuals and aguateros supply good quality piped water to areas unserved by the public water company. Unlike the public company, the aguateros allow payment of connection fees on installment, making it easier for low-income consumers to connect. * In Yemen, small-scale electricity providers innovatively meet the rural and village demand for electricity that the public utility does not meet. These entrants seldom duplicate investments, although some government intervention to ensure interconnection could improve efficiency. Limitations on entry may sometimes be justified for environmental reasons or to promote private sector investment, but those cases are rare. Legalizing alternative providers will allow them to expand and meet new needs. Limits on their entry may be needed sometimes, but limits should be the exception, not the rule, the authors argue. Generally, free entry should be allowed in power, water, and sanitation.Health Economics&Finance,Decentralization,Water and Industry,Economic Theory&Research,Environmental Economics&Policies,Town Water Supply and Sanitation,Environmental Economics&Policies,Health Economics&Finance,Water and Industry,Economic Theory&Research

System and method for the adaptive mapping of matrix data to sets of polygons

A system and method for converting bitmapped data, for example, weather data or thermal imaging data, to polygons is disclosed. The conversion of the data into polygons creates smaller data files. The invention is adaptive in that it allows for a variable degree of fidelity of the polygons. Matrix data is obtained. A color value is obtained. The color value is a variable used in the creation of the polygons. A list of cells to check is determined based on the color value. The list of cells to check is examined in order to determine a boundary list. The boundary list is then examined to determine vertices. The determination of the vertices is based on a prescribed maximum distance. When drawn, the ordered list of vertices create polygons which depict the cell data. The data files which include the vertices for the polygons are much smaller than the corresponding cell data files. The fidelity of the polygon representation can be adjusted by repeating the logic with varying fidelity values to achieve a given maximum file size or a maximum number of vertices per polygon

The earth community and ecological jurisprudence

Legal philosophical discourse tends to be animated by some conception of self and the parameters of community. Reflecting a vast heritage of humanist philosophy and theology, western legal concepts reflect anthropocentric values. Theories of law and legal concepts promote human beings as separate to the environment and define frameworks for the exploitation of nature. Against this paradigm, environmental philosophers have sought to redefine human beings as integral members of a greater Earth community – nature is a community of subjects, not a collection of objects. This alternative conception of self carries important consequences for legal philosophy. This paper explores these consequences first by analysing the ecological conception of self and community articulated by ‘geologian’ Thomas Berry (1914-2009). Second, this paper uses Berry’s analysis to develop an ecological theory of jurisprudence. This theory connects human law with ecological integrity and holds that human law attains legal quality (in part) when enacted for the common good of the comprehensive Earth community. Throughout this analysis, the paper also highlights the limitations Berry’s philosophical and legal writing and seeks dialogue with leftist political theory. El discurso filosófico jurídico tiende a estimularse por una concepción del individuo y por parámetros de comunidad. Como reflejo de una vasta herencia de la filosofía humanista y la teología, los conceptos jurídicos occidentales reflejan valores antropocéntricos. Teorías del derecho y conceptos legales promueven seres humanos separados del medio ambiente y definen los marcos para la explotación de la naturaleza. Frente a este paradigma, los filósofos ambientales han tratado de redefinir los seres humanos como miembros de una comunidad de la Tierra más amplia – la naturaleza es una comunidad de sujetos, no una colección de objetos. Esta concepción alternativa del individuo conlleva importantes consecuencias para la filosofía del derecho. Este artículo explora estas consecuencias, primero mediante el análisis de la concepción ecológica del individuo y de la comunidad articulada por el geólogo Thomas Berry (1914-2009). En segundo lugar, este trabajo utiliza el análisis de Berry para desarrollar una teoría ecológica de la jurisprudencia. Esta teoría conecta el derecho humano con la integridad ecológica y sostiene que el derecho humano alcanza (en parte) la calidad jurídica cuando se promulga por el bien común de la comunidad global de la Tierra. A lo largo de este análisis, el informe también pone de relieve las limitaciones de la escritura filosófica y jurídica de Berry y busca el diálogo con la teoría política de izquierdas

Differential effectiveness of residential versus outpatient aftercare for parolees from prison-based therapeutic community treatment programs

<p>Abstract</p> <p>Background</p> <p>Research has indicated that more intense treatment is associated with better outcomes among clients who are appropriately matched to treatment intensity level based on the severity of their drug/alcohol problem. This study examined the differential effectiveness of community-based residential and outpatient treatment attended by male and female drug-involved parolees from prison-based therapeutic community substance abuse treatment programs based on the severity of their drug/alcohol problem.</p> <p>Methods</p> <p>Subjects were 4,165 male and female parolees who received prison-based therapeutic community substance abuse treatment and who subsequently participated in <it>only </it>outpatient or <it>only </it>residential treatment following release from prison. The dependent variable of interest was return to prison within 12 months. The primary independent variables of interest were alcohol/drug problem severity (low, high) and type of aftercare (residential, outpatient). Chi-square analyses were conducted to examine the differences in 12-month RTP rates between and within the two groups of parolees (residential and outpatient parolees) based on alcohol/drug problem severity (low severity, high severity). Logistic regression analyses were performed to determine if aftercare modality (outpatient only vs. residential only) was a significant predictor of 12-month RTP rates for subjects who were classified as low severity versus those who were classified as high severity.</p> <p>Results</p> <p>Subjects benefited equally from outpatient and residential aftercare, regardless of the severity of their drug/alcohol problem.</p> <p>Conclusion</p> <p>As states and the federal prison system further expand prison-based treatment services, the demand and supply of aftercare treatment services will also increase. As this occurs, systems and policies governing the transitioning of individuals from prison- to community-based treatment should include a systematic and validated assessment of post-prison treatment needs and a valid and reliable means to assess the quality of community-based treatment services. They should also ensure that parolees experience a truly uninterrupted continuum of care through appropriate recognition of progress made in prison-based treatment.</p

Preferably, the graphical user interface includes one or more user-selectable options for graphically displaying at least one of convection information, turbulence information, icing information, weather satellite information, SIGMET information, significant weather prognosis information, and winds aloft information

Ethical Considerations for the Return of Incidental Findings in Ophthalmic Genomic Research

This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License. Available from PubMed Central (PMC).http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4757467/Whole genome and whole exome sequencing technologies are being increasingly used in research. However, they have the potential to identify incidental findings (IF), findings not related to the indication of the test, raising questions regarding researchers' responsibilities toward the return of this information to participants. In this study we discuss the ethical considerations related to the return of IF to research participants, emphasizing that the type of the study matters and describing the current practice standards. There are currently no legal obligations for researchers to return IF to participants, but some viewpoints consider that researchers might have an ethical one to return IF of clinical validity and clinical utility and that are actionable. The reality is that most IF are complex to interpret, especially since they were not the indication of the test. The clinical utility often depends on the participants' preferences, which can be challenging to conciliate and relies on participants' understanding. In summary, in the context of a lack of clear guidance, researchers need to have a clear plan for the disclosure or nondisclosure of IF from genomic research, balancing their research goals and resources with the participants' rights and their duty not to harm

Investigation of eight candidate genes on chromosome 1p36 for autosomal dominant total congenital cataract

Purpose: To identify the causative gene for autosomal dominant total congenital cataract in a six-generation Australian family displaying linkage to chromosome 1p36. Methods: Eight candidate genes (HSPB7, FBXO42, EFHD2, ZBTB17, CAPZB, FBLIM1, ALDH4A1, and MFAP2) from within the previously defined linkage interval were selected based on expression in lens and their known or putative function. The coding exons were sequenced in multiple affected family members and compared to the reference sequence. Results: No segregating mutations were identified in any of the eight genes. Thirty-one polymorphisms were detected, 20 of which were in the exons and 11 in the flanking introns. Conclusions: Coding mutations in HSPB7, FBXO42, EFHD2, ZBTB17, CAPZB, FBLIM1, ALDH4A1, and MFAP2 do not account for congenital cataract in this family
