The neoliberal period was accompanied by a momentous transformation within the US health care system. As the result of a number of political and historical dynamics, the healthcare law signed by President Barack Obama in 2010 ‑the Affordable Care Act (ACA)‑ drew less on universal models from abroad than it did on earlier conservative healthcare reform proposals. This was in part the result of the influence of powerful corporate healthcare interests. While the ACA expands healthcare coverage, it does so incompletely and unevenly, with persistent uninsurance and disparities in access based on insurance status. Additionally, the law accommodates an overall shift towards a consumerist model of care characterized by high cost sharing at time of use. Finally, the law encourages the further consolidation of the healthcare sector, for instance into units named “Accountable Care Organizations” that closely resemble the health maintenance organizations favored by managed care advocates. The overall effect has been to maintain a fragmented system that is neither equitable nor efficient. A single payer universal system would, in contrast, help transform healthcare into a social right.

Permanent magnet synchronous motors (PMSMs) provide a competitive technology for EV traction drives owing to their high power density and high efficiency. In this paper, three types of interior PMSMs with different PM arrangements are modeled by the finite element method (FEM). For a given amount of permanent magnet materials, the V-shape interior PMSM is found better than the U-shape and the conventional rotor topologies for EV traction drives. Then the V-shape interior PMSM is further analyzed with the effects of stator slot opening and the permanent magnet pole chamfering on cogging torque and output torque performance. A vector-controlled flux-weakening method is developed and simulated in Matlab to expand the motor speed range for EV drive system. The results show good dynamic and steady-state performance with a capability of expanding speed up to four times of the rated. A prototype of the V-shape interior PMSM is also manufactured and tested to validate the numerical models built by the FEM.

The advancement of GPS technology has made it possible to use GPS devices as orientation and navigation tools, but also as tools to track spatiotemporal information. GPS tracking data can be broadly applied in location-based services, such as spatial distribution of the economy, transportation routing and planning, traffic management and environmental control. Therefore, knowledge of how to process the data from a standard GPS device is crucial for further use. Previous studies have considered various issues of the data processing at the time. This paper, however, aims to outline a general procedure for processing GPS tracking data. The procedure is illustrated step-by-step by the processing of real-world GPS data of car movements in Borlänge in the centre of Sweden.

This paper is reviewing objective assessments of Parkinson’s disease(PD) motor symptoms, cardinal, and dyskinesia, using sensor systems. It surveys the manifestation of PD symptoms, sensors that were used for their detection, types of signals (measures) as well as their signal processing (data analysis) methods. A summary of this review’s finding is represented in a table including devices (sensors), measures and methods that were used in each reviewed motor symptom assessment study. In the gathered studies among sensors, accelerometers and touch screen devices are the most widely used to detect PD symptoms and among symptoms, bradykinesia and tremor were found to be mostly evaluated. In general, machine learning methods are potentially promising for this. PD is a complex disease that requires continuous monitoring and multidimensional symptom analysis. Combining existing technologies to develop new sensor platforms may assist in assessing the overall symptom profile more accurately to develop useful tools towards supporting better treatment process.

Motor vehicle theft costs dearly to the Australian economy. Conservative estimates have put the annual cost of this form of illegal activity at 654 million during 1996. A number of initiatives aimed at reducing the incidence and cost of car theft have been implemented in recent years, yet statistics indicate that car theft is on the increase. Several authors have proposed an integrated approach to the regulation of markets for stolen property. Understanding property crime as a market is central to identifying approaches to its control. This paper discusses an industry model of crime and develops it on Australian data. Our model is an adaptation of one originally proposed by Vandeale (1978). It considers a production sector that uses inputs from a market of illegal labour to generate a supply of illegal goods that are traded in a product market. These sectors interact with each other and with a criminal justice sector. The model is applied to the analysis of car theft in Queensland.

Los porteros de f?tbol son un componente muy importante dentro de un equipo de f?tbol donde se debe tener en cuenta las caracter?sticas de este a la hora de selecci?n deportiva y especificidad del jugador ya que de dicha selecci?n depende del futuro de un talento deportivo. El objetivo de este estudio fue determinar las caracter?sticas antropom?tricas y motoras de los porteros de la escuela de f?tbol de la Universidad del Valle categor?a pre-juvenil en un estudio de car?cter descriptivo y de corte transversal. Para lograr este objetivo se evaluaron 10 futbolistas en la posici?n de porteros con edades de 13 y 14 a?os de edad ni?as de 12 y 13 a?os pertenecientes a la escuela de futbol de la universidad del valle. Se midieron variables antropom?tricas como masa corporal, estatura, I.M.C, envergadura; mediciones de per?metros como t?rax, brazo contra?do, brazo relajado, antebrazo, cintura, cadera, muslo, pierna; para la composici?n corporal se midieron los pliegues subescapular, tr?ceps, b?ceps, antebrazo, t?rax, supra-il?aco, abdomen, muslo, pierna y para el componente de desarrollo motor: resistencia, velocidad, fuerza miembro superior e inferior. En general nuestros porteros de 14 y 15 a?os obtuvieron promedios similares en todas las variables, las diferencias observadas en sus promedios son normales durante el crecimiento y desarrollo. Hubo muchas diferencias en los promedios arrojados en el componente de flexibilidad ya que este fue donde sacaron un promedio no favorable y programar trabajar esta cualidad en los entrenamientos.

The asynchronous polyphase induction motor has been the motor of choice in industrial settings for about the past half century because power electronics can be used to control its output behavior. Before that, the dc motor was widely used because of its easy speed and torque controllability. The two main reasons why this might be are its ruggedness and low cost. The induction motor is a rugged machine because it is brushless and has fewer internal parts that need maintenance or replacement. This makes it low cost in comparison to other motors, such as the dc motor. Because of these facts, the induction motor and drive system have been gaining market share in industry and even in alternative applications such as hybrid electric vehicles and electric vehicles. The subject of this thesis is to ascertain various control algorithms’ advantages and disadvantages and give recommendations for their use under certain conditions and in distinct applications. Four drives will be compared as fairly as possible by comparing their parameter sensitivities, dynamic responses, and steady-state errors. Different switching techniques are used to show that the motor drive is separate from the switching scheme; changing the switching scheme produces entirely different responses for each motor drive.

Em tempos de grandes argumentações em torno da globalização, temos vindo a assistir, em Portugal, e um pouco por todo o mundo, à discussão sobre a autonomia dos indivíduos e das instituições. Ao mesmo tempo, discutem-se as vantagens e desvantagens, não só dessa autonomia, mas também de uma maior desconcentração e descentralização por parte do Estado, em geral, e dentro de cada uma das suas unidades orgânicas. O Ministério da Educação português não tem estado alheio a esta discussão e tem produzido legislação no sentido de as concretizar. O presente estudo alinha-se nestas preocupações e tenta determinar se às escolas públicas enquanto instituições estatais, garante do ensino público, tem sido outorgada essa autonomia e qual o seu grau de exercício. Em simultâneo visa aferir das dificuldades que esse processo descentralizador tem vindo experimentar.

The male gametophyte of the semi-aquatic fern, Marsilea vestita, produces multiciliated spermatozoids in a rapid developmental sequence that is controlled post-transcriptionally when dry microspores are placed in water. Development can be divided into two phases, mitosis and differentiation. During the mitotic phase, a series of nine successive division cycles produce 7 sterile cells and 32 spermatids in 4.5-5 hours. During the next 5-6 hours, each spermatid differentiates into a corkscrew-shaped motile spermatozoid with ~140 cilia. This document focuses on the role of motor proteins in the regulation of male gametophyte development and during ciliogenesis. In order to study the mechanisms that regulate spermatogenesis, RNAseq was used to generate a reference transcriptome that allowed us to assess the abundance of transcripts at different stages of development. Over 120 kinesin-like sequences were identified in the transcriptome that represent 56 unique kinesin transcripts. Members of the kinesin-2, -4, -5, -7, -8, -9, -12, -13, and -14 families, in addition to several plant specific and ‘orphan’ kinesins are present. Most (91%) of these kinesin transcripts change in abundance throughout gametophyte development, with 52% of kinesin mRNAs enriched during the mitotic phase and 39% enriched during differentiation. Functional analyses show that the temporal regulation of kinesin transcripts during gametogenesis directly correlates with kinesin protein function. Specifically, Marsilea makes one kinesin-2 (MvKinesin-2) and two kinesin-9 (MvKinesin-9A and MvKinesin-9B) transcripts, which are present during spermatid differentiation and ciliogenesis. Silencing experiments showed that MvKinesin-2 and MvKinesin-9A are required for ciliogenesis and motility in the Marsilea male gametophyte; however, these kinesins display atypical roles during these processes. In contrast, spermatozoids produced after the silencing of MvKinesin-9B exhibit normal morphology. MvKinesin-2 is necessary for cytokinesis as well as for regulating ciliary length and MvKinesin-9A is needed for the correct orientation of basal bodies, events not typically associated with these proteins. In addition, Marsilea makes motile, ciliated gametophytes without the help of IFT dynein, outer arm dynein, or the BBsome. These results are the first to investigate the kinesin-linked mechanisms that regulate ciliogenesis in a land plant.

A Repartição de Operações do Estado-Maior do Corpo Expedicionário Português foi responsável pela coordenação das tropas portuguesas na frente ocidental e pela integração da força no dispositivo britânico. Elaborou o plano de defesa do setor atribuído e emitiu uma série de ordens para gerir as operações correntes. Com este trabalho pretendeu-se compreender a atividade desta repartição e o respetivo impacto no desempenho operacional do Corpo. Foram identificados os fatores que marcaram a beligerância portuguesa, que mais influência tiveram na repartição e no desempenho do Corpo, avaliado o impacto da estrutura da força e do seu Estado-Maior, identificados os fatores mais relevantes do setor atribuído e do seu dispositivo com impacto no desempenho e ainda determinado o papel da repartição durante a condução das operações. Com o intuito de atingir os objetivos propostos, foi analisado um conjunto de fontes, fundamentalmente do Arquivo Histórico Militar e da Biblioteca do Exército, para recolha de informação, e bibliografia nacional e estrangeira acerca do tema. Concluímos que a repartição contribuiu para o normal desempenho do CEP, não tendo sido identificados erros cometidos pela mesma com impacto negativo na prestação da força. Abstract: The Operations Division of the General Staff of the Portuguese Expeditionary Corps was responsible for coordinating the Portuguese troops on the western front and for the integration of the force in British defense system. It prepared the defense plan for the assigned sector, and issued several orders to manage current operations. This work was intended to understand the activity of this division and its impact on the operational performance of CEP. Were identified the factors that marked the Portuguese belligerence which more influence had in the Operations Division and CEP's performance, assessed the impact of the force structure and its staff, identified the most important factors of the assigned sector and its force structure with impact on performance and also determined the role of the operations division during the operations. In order to achieve the proposed goals, we studied a number of sources, mainly from the Military Historical Archives and the Library of the Army for information collection, and also from national and foreign literature on the subject. We conclude that the operations division contributed to the normal performance of the CEP, and didn’t identify errors committed by it with negative impact on the force performance.
