The uneasy case for lower parking standards

Minimum parking requirements are the norm for urban and suburban development in the United States (Davidson and Dolnick (2002)). The justification for parking space requirements is that overflow parking will occupy nearby street or off-street parking. Shoup (1999) and Willson (1995) provides cases where there is reason to believe that parking space requirements have forced parcel developers to place more parking than they would in the absence of parking requirements. If the effect of parking minimums is to significantly increase the land area devoted to parking, then the increase in impervious surfaces would likely cause water quality degradation, increased flooding, and decreased groundwater recharge. However, to our knowledge the existing literature does not test the effect of parking minimums on the amount of lot space devoted to parking beyond a few case studies. This paper tests the hypothesis that parking space requirements cause an oversupply of parking by examining the implicit marginal value of land allocated to parking spaces. This is an indirect test of the effects of parking requirements that is similar to Glaeser and Gyourko (2003). A simple theoretical model shows that the marginal value of additional parking to the sale price should be equal to the cost of land plus the cost of parking construction. We estimate the marginal values of parking and lot area with spatial methods using a large data set from the Los Angeles area non-residential property sales and find that for most of the property types the marginal value of parking is significantly below that of the parcel area. This evidence supports the contention that minimum parking requirements significantly increase the amount of parcel area devoted to parking.

A segurança das infraestruturas críticas em Portugal

Portugal, having responsibilities at European level, needs to ensure compliance with European standards, particularly with regard to the European Security Plan for Critical Infrastructures. National critical infrastructures should be a focus of attention with regard to the management of public risks, since these represent "a set of services that are essential to the functioning of the country and the functioning of the forces that ensure national defense." (Soares, 2008) This contribution on national critical infrastructures (CI) has the essential objective of clarifying the development of the strategy adopted by Portugal in pursuit of the security of these fundamental infrastructures. The goal lies not only through producing a descriptive document, but also carry a brief confrontation between the legal framework related to these subjects and the reality in which the Critical Infrastructure Operators and the National Civil Protection Authority (ANPC) operate. It is intended, in this sense, to understand the development of the project for the national security program of critical infrastructures and what effects of its measures on operators. As for the methodology, we followed a methodological strategy, where we combine the literature with data obtained through semi-structured interviews. Portugal, being a geographically peripheral country and having no record of incidents capable of causing major contingencies in key services for the normal development of society, does not have a structured and regulator plan that substantiates the need for operators responsible for CI to invest in security. This same approach is expected at the State level, believing that even though this theme has be widely explored by international institutions, Portugal has not yet tried to give the attention it deserves. Without the existence of an institution and a regulatory system, CI operators can become less available to comply with the legal framework.

Differences and reasons in IASB accounting standards between small and large companies

This paper studies the main differences in accounting standards of the International Accounting Standards Board (IASB) between small and large companies, materialised in the dissimilarities between the International Financial Reporting Standard for Small and Medium-sized Entities and the full International Financial Reporting Standards, as of 2010. Another element of this project is the analysis of the reasons behind the differences between the two aforementioned frameworks, which intends to expose the rationale and the mindset that led to an adaptation of the full standards in a stand-alone document designed for small companies.

Introducing mapping standards in the quality assessment of buildings extracted from very high resolution satellite imagery

Many municipal activities require updated large-scale maps that include both topographic and thematic information. For this purpose, the efficient use of very high spatial resolution (VHR) satellite imagery suggests the development of approaches that enable a timely discrimination, counting and delineation of urban elements according to legal technical specifications and quality standards. Therefore, the nature of this data source and expanding range of applications calls for objective methods and quantitative metrics to assess the quality of the extracted information which go beyond traditional thematic accuracy alone. The present work concerns the development and testing of a new approach for using technical mapping standards in the quality assessment of buildings automatically extracted from VHR satellite imagery. Feature extraction software was employed to map buildings present in a pansharpened QuickBird image of Lisbon. Quality assessment was exhaustive and involved comparisons of extracted features against a reference data set, introducing cartographic constraints from scales 1:1000, 1:5000, and 1:10,000. The spatial data quality elements subject to evaluation were: thematic (attribute) accuracy, completeness, and geometric quality assessed based on planimetric deviation from the reference map. Tests were developed and metrics analyzed considering thresholds and standards for the large mapping scales most frequently used by municipalities. Results show that values for completeness varied with mapping scales and were only slightly superior for scale 1:10,000. Concerning the geometric quality, a large percentage of extracted features met the strict topographic standards of planimetric deviation for scale 1:10,000, while no buildings were compliant with the specification for scale 1:1000.

O fenómeno da criminalidade itinerante

In an increasingly globalized society, the crime appears as a reality that crosses borders. Globalization has potentiated the emergence of new forms of crime, which have been the subject of more interventional, particularly in terms of political, judicial and police authorities as well as civil society approaches. The media allow rapid expansion of criminal methodologies, which aggregate to the ease of movement of itinerant criminal groups, increases the opportunities for the continuation of the practice of criminal offenses, threatening, increasingly, the tranquility and safety of populations. Criminal organizations are characterized by their complexity, thus contributing to the difficulty in combat, by police and judicial authorities, forcing rapid adaptation to new political and criminal reality, particularly at the level of institutional cooperation, national and international, as exemplified by the creation of the "European Area of Freedom, Security and Justice" and new agencies in the field of police cooperation. It was intended with this paper to answer the central question: Is it possible to define a concept of Itinerant Crime in the European regulatory framework (Police and Judiciary)? To fulfill this aim, we performed the characterization of the concept of itinerant crime including itinerant criminal group, we analyzed the work that is being done by the authorities, police and judiciary, in order to contain the phenomenon. Finally, we studied type of existing cooperation at European level between the Member States and the authorities with responsibilities in this area. At the end, we conclude that efforts are being made towards the enhancement of operational, police and judicial cooperation, between the competent authorities of the European Union by combating this phenomenon. Define, and also proposed, a unique concept of Itinerant Crime, in order to be included in the legal standards, in order to facilitate research, in particular to better fit the itinerant crime and assist the prosecution of offenders.

The effect of secular trends in the classroom furniture mismatch: support for continuous update of school furniture standards

In order to create safer schools, the Chilean authorities published a Standard regarding school furniture dimensions. The aims of this study are twofold: to verify the existence of positive secular trend within the Chilean student population and to evaluate the potential mismatch between the anthropometric characteristics and the school furniture dimensions defined by the mentioned standard. The sample consists of 3078 subjects. Eight anthropometric measures were gathered, together with six furniture dimensions from the mentioned standard. There is an average increase for some dimensions within the Chilean student population over the past two decades. Accordingly, almost 18% of the students will find the seat height to be too high. Seat depth will be considered as being too shallow for 42.8% of the students. It can be concluded that the Chilean student population has increased in stature, which supports the need to revise and update the data from the mentioned Standard. Practitioner Summary: Positive secular trend resulted in high levels of mismatch if furniture is selected according to the current Chilean Standard which uses data collected more than 20 years ago. This study shows that school furniture standards need to be updated over time.

Genetic regulatory mechanisms by means of extended interactive Petri nets

In our work we have chosen to integrate formalism for knowledge representation with formalism for process representation as a way to specify and regulate the overall activity of a multi-cellular agent. The result of this approach is XP,N, another formalism, wherein a distributed system can be modeled as a collection of interrelated sub-nets sharing a common explicit control structure. Each sub-net represents a system of asynchronous concurrent threads modeled by a set of transitions. XP,N combines local state and control with interaction and hierarchy to achieve a high-level abstraction and to model the complex relationships between all the components of a distributed system. Viewed as a tool XP,N provides a carefully devised conflict resolution strategy that intentionally mimics the genetic regulatory mechanism used in an organic cell to select the next genes to process.

Participación de las células supresoras mieloides (CSM) y T regulatorias (Treg) en el control de la infección con Trypanosoma cruzi y el desarrollo de la patología inflamatoria asociada a la infeccion. Role of Myeloid-Derived Suppressor Cells and regulatory T cells in the control of T. cruzi infection and the infection-associated pathology.

La infección de mamíferos con el T. cruzi resulta en diferentes alteraciones inmunológicas que permiten la persistencia crónica del parásito y destrucción inflamatoria progresiva del tejido cardiaco, nervioso y hepático. Los mecanismos responsables de la patología de la enfermedad de Chagas han sido materia de intensa investigación habiéndose propuesto que el daño producido en esta enfermedad puede ser consecuencia de la respuesta inflamatoria del individuo infectado y/o de una acción directa del parásito sobre los tejidos del hospedador. El propósito del presente proyecto es estudiar comparativamente, en dos cepas de ratones con diferente susceptibilidad a la infección y desarrollo de patología, la participación y los mecanismos efectores de las células supresoras mieloides (CSM) y las celulas T regulatorias inducidas por la infección experimental con Trypanosoma cruzi en el control de la infección con este protozoario y en el desarrollo de la patología hepática siendo los objetivos especificos desarrolar: - Investigar la generación y/o reclutamiento de células de CSM en bazo e hígado de ratones infectados con Trypanosoma cruzi y su contribución a la desigual susceptibilidad a la infección y respuesta inmune desarrollada en las cepas de ratones BALB/c y C57BL/6; - Investigar la capacidad de las CSM inducidas por la infección con T. cruzi en bazo e hígado de ratones de ambas cepas para suprimir la respuesta de células T in vitro e indagar sobre los mecanismos de supresión utilizados; - Investigar la generación y/o reclutamiento de células Treg durante la infección experimental con Trypanosoma cruzi, su participación en la desigual susceptibilidad a la infección y respuesta inmune desarrollada en ambas cepas de ratones y los mecanismos de supresión utilizados. - Analizar en tejido hepático o leucocitos infiltrantes la presencia de COX2, PGE2, MMP2 y 9, IL1b, IL6, IDO, IL10 y GM-CSF capaces de inducir la expansión de las CSM; - Dilucidar si la administración del ligando para TLR2 (Pam3CyS) previo a la infección de ratones C57BL/6 (en los cuales se detecta un menor número de CSM) es capaz de modular la respuesta inflamatoria y el daño hepático a través de la inducción de CSM y/o T reg en hígado y bazo. La comprension de los eventos celulares y moleculares que regulan la producción de citoquinas pro- y anti-inflamatorias y otros mediadores, así como el papel de los receptores de la inmunidad innata durante la infección con T. cruzi contribuirá a responder interrogantes que son claves para el diseño de nuevas estrategias de intervención inmune tendientes a preservar los mecanismos de defensa del huésped. Two nonexclusive mechanisms have been proposed to explain the Chagas’s disease pathology: 1) The pathology of the disease seems to be consequence of the inflammatory response triggered for the parasite; or 2) The damage is produced by the parasite direct effect. Recently, we reported that TLR2, TLR4 and TLR9 (innate immune response receptors) are differentially modulated in injured livers from BALB/c (lesser liver pathology) and C57BL/6 (elevated liver pathology) mice during Trypanosoma cruzi infection. The aim of our proposal is the study of role of Myeloid-Derived Suppressor Cells (MDSC) and regulatory T cells in the control of T. cruzi infection and the infection-associated pathology. Our specific aims are: -To study the induction or recruitment of MDSC in splenn and liver of BALB/c and C57BL/6 mice and their relationship with the differential susceptibility and immune response observed in these both mice strains; - To determine the ability and the mechanisms used by the T. cruzi-induced MDSC to suppress the T cell proliferative response; -To study the induction or recruitment of Treg in liver of BALB/c and C57BL/6 mice and their relationship with the differential susceptibility and immune response observed in these both mice strains; -To analize in liver tissue or tissue infiltrating lymphocytes the activation of COX2, PGE2, MMP2 y 9, IL1b, IL6, IDO, IL10 y GM-CSF known to promote the development of MDSC; -To determine whether the treatment with Pam3CyS (TLR2 ligand) is able to modulate the liver inflammatory respose and damage througth the induction of MDSC or Treg.

A comparison of environmental licensing systems in operation in the wood panel manufacturing industry in the Northern Hemisphere

The objective of this thesis is to compare and contrast environmental licensing systems, for the wood panel industry, in a number of countries in order to determine which system is the best from an environmental and economic point of view. The thesis also examines the impact which government can have on industry and the type of licensing system in operation in a country. Initially, the thesis investigates the origins of the various environmental licensing systems which are in operation in Ireland, Scotland, Wales, France, USA and Canada. It then examines the Environmental Agencies which control and supervise industry in these countries. The impact which the type of government (i.e. unitary or federal) in charge in any particular country has on industry and the Regulatory Agency in that country is then described. Most of the mills in the thesis make a product called OSB (Oriented Strand Board) and the manufacturing process is briefly described in order to understand where the various emissions are generated. The main body of the thesis examines a number of environmental parameters which have emission limit values in the licenses examined, although not all of these parameters have emission limit values in all of the licenses. All of these parameters are used as indicators of the potential impact which the mill can have on the environment. They have been set at specific levels by the Environmental Agencies in the individual countries to control the impact of the mill. Following on from this, the two main types of air pollution control equipment (WESPs and RTOs) are described in regard to their function and capabilities. The mill licenses are then presented in the form of results tables which compare air results and water results separately. This is due to the fact that the most significant emission from this type of industry is to air. A matrix system is used to compare the licenses so that the comparison can be as objective as possible. The discussion examines all of the elements previously described and from this it was concluded that the IPC licensing system is the best from an environmental and economic point of view. It is a much more expensive system to operate than the other systems examined, but it is much more comprehensive and looks at the mill as a whole rather than fragmenting it. It was also seen that the type of environmental licensing system which is in place in a country can play a role in the locating of an industry as certain systems were seen to have more stringent standards attached to them. The type of standard in place in a country is in turn influenced by the type of government which is in place in that country.
