Efeitos do conhecimento de resultados autocontrolado na aprendizagem motora

O objetivo do presente estudo foi analisar três diferentes estratégias de fornecer conhecimento de resultados (CR): autocontrolado, yoked pareado por tentativa e yoked pareado pela frequência média total de CR, na prática aleatória. A amostra foi constituída por 45 voluntários universitários, distribuídos em três grupos (n= 15 sujeitos). A tarefa consistiu em pressionar as teclas 2, 4, 8 e 6 do teclado numérico de um computador, em três diferentes tempos alvo (700, 900 e 1100 ms), praticados aleatoriamente. O experimento constou de fase de aquisição e testes de retenção e transferência atrasados. A análise dos dados foi realizada por meio da ANOVA e não foi constatada diferença significativa entre os grupos. Os resultados demonstraram que não houve efeito das frequências autocontroladas para a aprendizagem motora quando se utiliza a prática aleatória. Além disso, uma nova possibilidade de parear o grupo autocontrolado foi apresentada.

Värdet bakom våldtäkten : En diskursanalys av fyra rättsfall

This paper seeks to explore how victims of crime and defendants are portrayed in sexual assault cases. Lately, more and more voices have been raised in appal against values demonstrated in court decisions and we’ve seen the implementation of a new sexual assault legislation in attempt to increase people’s sexual integrity. Yet, at the same time, there is still a tremendously low amount of reported sexual assaults that go to trial and even fewer result in conviction. This paper is not an attempt to scrutinize the legal system, but to draw attention to what values are portrayed in sexual assault cases. The purpose is to examine the court decisions under consideration to see if and what values are portrayed. My paper can in no way allow generalization; it is merely a small sample of reality. The data consists of four court decisions from Östersund’s Tingsrätt; two of them resulting in conviction and two of them in dismissal. The data was collected systematically and undergoes a discourse analysis; hence it is a qualitative study. The result of the analysis is that although somewhat subtle, the court decisions do indeed portray stereotypical gender roles, particularly regarding victims’ prior sexual history, women’s room to manoeuvre and their given life conditions

Decrescita sostenibile applicata alla mobilità nelle aree urbane.

La mobilità nelle aree urbane di medie e grandi dimensioni risente di molte criticità e spesso è causa di numerose discussioni. L'utilizzo sempre crescente del mezzo di trasporto privato ha prodotto conseguenze negative: l'aumento del traffico e degli incidenti stradali, dell'inquinamento atmosferico e del rumore sono accompagnati da un forte spreco energetico. Dall'altra parte, il trasporto pubblico locale (TPL) non è riuscito a costruirsi canali preferenziali all'interno dell'immaginario cittadino, poiché sottomesso da un modello economico e un mercato fortemente dipendenti dall'automobile. Una via d'uscita dalla mobilità non sostenibile basata sull'utilizzo di combustibili fossili porta a concepire un trasporto pubblico locale gratuito, fruibile dal cittadino in qualsiasi momento della giornata. Attraverso un'analisi dell'azienda del trasporto pubblico bolognese (ATC) e dei dati provenienti dalla sanità regionale, questa tesi intende mostrare che vi sarà un miglioramento della qualità di vita in aree urbane nel momento in cui la teoria della decrescita venga condivisa da tutti i cittadini. Così sarà possibile liberare i centri urbani dai mezzi privati e quindi dagli alti livelli di inquinamento acustico e atmosferico, e dare ai cittadini la vera libertà di movimento. Mobility in medium and large sized urban areas is critical and often a cause for numerous debates. The use of private transport is in constant increase and has generated negative consequences: congestion and road accidents, air and noise pollutio as well as a considerable waste of energy. On the other hand, the local public transport (LPT) has not succeeded in representing the preferred choice by citizens in the urban imaginary. Its potential has been subdued by economic models and markets that are largely dependant on the production of vehicles. An alternative to the current non sustainable mobility based on the combustion of fossil fuels could be the provision of a free local transport network available to the citizen from anywhere at any time. This dissertation's objective is to show how an improvement of the quality of life in urban areas is connected to a collective awareness on the degrowth theory. I intend to achieve this by analysing thoroughly the system of the public transportation agency in Bologna (ATC) and considering data from the local health department. Only then we will be able to limit private vehicles from city centres and as a result of that drastically decrease air and noise pollution whilst providing a true service for a free moving citizen.

Sistemi riconfigurabili a basso consumo per applicazioni di monitoraggio distribuito

The term Ambient Intelligence (AmI) refers to a vision on the future of the information society where smart, electronic environment are sensitive and responsive to the presence of people and their activities (Context awareness). In an ambient intelligence world, devices work in concert to support people in carrying out their everyday life activities, tasks and rituals in an easy, natural way using information and intelligence that is hidden in the network connecting these devices. This promotes the creation of pervasive environments improving the quality of life of the occupants and enhancing the human experience. AmI stems from the convergence of three key technologies: ubiquitous computing, ubiquitous communication and natural interfaces. Ambient intelligent systems are heterogeneous and require an excellent cooperation between several hardware/software technologies and disciplines, including signal processing, networking and protocols, embedded systems, information management, and distributed algorithms. Since a large amount of fixed and mobile sensors embedded is deployed into the environment, the Wireless Sensor Networks is one of the most relevant enabling technologies for AmI. WSN are complex systems made up of a number of sensor nodes which can be deployed in a target area to sense physical phenomena and communicate with other nodes and base stations. These simple devices typically embed a low power computational unit (microcontrollers, FPGAs etc.), a wireless communication unit, one or more sensors and a some form of energy supply (either batteries or energy scavenger modules). WNS promises of revolutionizing the interactions between the real physical worlds and human beings. Low-cost, low-computational power, low energy consumption and small size are characteristics that must be taken into consideration when designing and dealing with WSNs. To fully exploit the potential of distributed sensing approaches, a set of challengesmust be addressed. Sensor nodes are inherently resource-constrained systems with very low power consumption and small size requirements which enables than to reduce the interference on the physical phenomena sensed and to allow easy and low-cost deployment. They have limited processing speed,storage capacity and communication bandwidth that must be efficiently used to increase the degree of local ”understanding” of the observed phenomena. A particular case of sensor nodes are video sensors. This topic holds strong interest for a wide range of contexts such as military, security, robotics and most recently consumer applications. Vision sensors are extremely effective for medium to long-range sensing because vision provides rich information to human operators. However, image sensors generate a huge amount of data, whichmust be heavily processed before it is transmitted due to the scarce bandwidth capability of radio interfaces. In particular, in video-surveillance, it has been shown that source-side compression is mandatory due to limited bandwidth and delay constraints. Moreover, there is an ample opportunity for performing higher-level processing functions, such as object recognition that has the potential to drastically reduce the required bandwidth (e.g. by transmitting compressed images only when something ‘interesting‘ is detected). The energy cost of image processing must however be carefully minimized. Imaging could play and plays an important role in sensing devices for ambient intelligence. Computer vision can for instance be used for recognising persons and objects and recognising behaviour such as illness and rioting. Having a wireless camera as a camera mote opens the way for distributed scene analysis. More eyes see more than one and a camera system that can observe a scene from multiple directions would be able to overcome occlusion problems and could describe objects in their true 3D appearance. In real-time, these approaches are a recently opened field of research. In this thesis we pay attention to the realities of hardware/software technologies and the design needed to realize systems for distributed monitoring, attempting to propose solutions on open issues and filling the gap between AmI scenarios and hardware reality. The physical implementation of an individual wireless node is constrained by three important metrics which are outlined below. Despite that the design of the sensor network and its sensor nodes is strictly application dependent, a number of constraints should almost always be considered. Among them: • Small form factor to reduce nodes intrusiveness. • Low power consumption to reduce battery size and to extend nodes lifetime. • Low cost for a widespread diffusion. These limitations typically result in the adoption of low power, low cost devices such as low powermicrocontrollers with few kilobytes of RAMand tenth of kilobytes of program memory with whomonly simple data processing algorithms can be implemented. However the overall computational power of the WNS can be very large since the network presents a high degree of parallelism that can be exploited through the adoption of ad-hoc techniques. Furthermore through the fusion of information from the dense mesh of sensors even complex phenomena can be monitored. In this dissertation we present our results in building several AmI applications suitable for a WSN implementation. The work can be divided into two main areas:Low Power Video Sensor Node and Video Processing Alghoritm and Multimodal Surveillance . Low Power Video Sensor Nodes and Video Processing Alghoritms In comparison to scalar sensors, such as temperature, pressure, humidity, velocity, and acceleration sensors, vision sensors generate much higher bandwidth data due to the two-dimensional nature of their pixel array. We have tackled all the constraints listed above and have proposed solutions to overcome the current WSNlimits for Video sensor node. We have designed and developed wireless video sensor nodes focusing on the small size and the flexibility of reuse in different applications. The video nodes target a different design point: the portability (on-board power supply, wireless communication), a scanty power budget (500mW),while still providing a prominent level of intelligence, namely sophisticated classification algorithmand high level of reconfigurability. We developed two different video sensor node: The device architecture of the first one is based on a low-cost low-power FPGA+microcontroller system-on-chip. The second one is based on ARM9 processor. Both systems designed within the above mentioned power envelope could operate in a continuous fashion with Li-Polymer battery pack and solar panel. Novel low power low cost video sensor nodes which, in contrast to sensors that just watch the world, are capable of comprehending the perceived information in order to interpret it locally, are presented. Featuring such intelligence, these nodes would be able to cope with such tasks as recognition of unattended bags in airports, persons carrying potentially dangerous objects, etc.,which normally require a human operator. Vision algorithms for object detection, acquisition like human detection with Support Vector Machine (SVM) classification and abandoned/removed object detection are implemented, described and illustrated on real world data. Multimodal surveillance: In several setup the use of wired video cameras may not be possible. For this reason building an energy efficient wireless vision network for monitoring and surveillance is one of the major efforts in the sensor network community. Energy efficiency for wireless smart camera networks is one of the major efforts in distributed monitoring and surveillance community. For this reason, building an energy efficient wireless vision network for monitoring and surveillance is one of the major efforts in the sensor network community. The Pyroelectric Infra-Red (PIR) sensors have been used to extend the lifetime of a solar-powered video sensor node by providing an energy level dependent trigger to the video camera and the wireless module. Such approach has shown to be able to extend node lifetime and possibly result in continuous operation of the node.Being low-cost, passive (thus low-power) and presenting a limited form factor, PIR sensors are well suited for WSN applications. Moreover techniques to have aggressive power management policies are essential for achieving long-termoperating on standalone distributed cameras needed to improve the power consumption. We have used an adaptive controller like Model Predictive Control (MPC) to help the system to improve the performances outperforming naive power management policies.

I limiti al diritto di proprietà derivanti dagli strumenti di pianificazione urbanistica. I vincoli urbanistici.

Nella prima parte viene ricostruito il concetto di vincolo espropriativo alla luce dell’elaborazione della giurisprudenza della Corte costituzionale e della Corte EDU, giungendo alla conclusione che rientrano in tale concetto le limitazioni al diritto di proprietà che: - derivano da scelte discrezionali dell’Amministrazione non correlate alle caratteristiche oggettive del bene; - superano la normale tollerabilità nel senso che impediscono al proprietario la prosecuzione dell’uso in essere o incidono sul valore di mercato del bene in modo sproporzionato rispetto alle oggettive caratteristiche del bene e all’interesse pubblico perseguito. Ragione di fondo della teoria dei vincoli è censurare l’eccessiva discrezionalità del potere urbanistico, imponendo una maggiore obiettività e controllabilità delle scelte urbanistiche. Dalla teoria dei vincoli consegue altresì che nell’esercizio del potere urbanistico l’Amministrazione, pur potendo differenziare il territorio, deve perseguire l’obiettivo del riequilibrio economico degli interessi incisi dalle sue determinazioni. L’obbligo della corresponsione dell’indennizzo costituisce la prima forma di perequazione urbanistica. Nel terzo e nel quarto capitolo viene analizzata la giurisprudenza civile e amministrativa in tema di vincoli urbanistici, rilevandone la non corrispondenza rispetto all’elaborazione della Corte costituzionale e l’incongruità dei risultati applicativi. Si evidenzia in particolare la necessità del superamento del criterio basato sulla distinzione zonizzazioni-localizzazioni e di considerare conformative unicamente quelle destinazioni realizzabili ad iniziativa privata che in concreto consentano al proprietario di conseguire un’utilità economica proporzionata al valore di mercato del bene. Nel quinto capitolo viene analizzato il rapporto tra teoria dei vincoli e perequazione urbanistica, individuandosi il discrimine tra i due diversi istituti non solo nel consenso, ma anche nella proporzionalità delle reciproche prestazioni negoziali. Attraverso la perequazione non può essere attribuito al proprietario un’utilità inferiore a quella che gli deriverebbe dall’indennità di esproprio.

Interpretare per il Tribunale penale internazionale per il Ruanda. Il trauma vicario e le sue conseguenze sul lavoro degli interpreti.

This dissertation discusses the professional figure of interpreters working for the International Criminal Tribunal for Rwanda (ICTR). The objective is to investigate specific job-related stress factors, particularly the psychological consequences interpreters may have to face, the so-called vicarious trauma. People working for the ICTR are exposed to genocide victims’ violent and shocking testimonies, a situation that could have negative psychological impacts. Online interviews with some interpreters working for the ICTR were carried out in order to arrive at a more thorough understanding of this topic. The study is divided into four chapters. Chapter I outlines the historical aspects of the simultaneous interpreting service in the legal field at the International Military Tribunal, in the trials of the Nazi leaders, and then it analyses a modern international criminal jurisdiction, the ICTR. Chapter II firstly discusses the differences between conference interpreting and court interpreting and in the second part it investigates job-related stress factors for interpreters, focusing on the legal field. Chapter III contains a detailed analysis of vicarious trauma: the main goal is to understand what psychological consequences interpreters have to cope with as a result of translating abused people’s accounts. Chapter IV examines the answers given by ICTR interpreters to the online interviews. The data collected from the interview was compared with the literature survey and the information derived from their comparison was used to put forward some suggestions for studies to be carried out in the future.

Investigating the effect of construction management strategies on project greenhouse gas emissions using interactive simulation

The challenges posed by global climate change are motivating the investigation of strategies that can reduce the life cycle greenhouse gas (GHG) emissions of products and processes. While new construction materials and technologies have received significant attention, there has been limited emphasis on understanding how construction processes can be best managed to reduce GHG emissions. Unexpected disruptive events tend to adversely impact construction costs and delay project completion. They also tend to increase project GHG emissions. The objective of this paper is to investigate ways in which project GHG emissions can be reduced by appropriate management of disruptive events. First, an empirical analysis of construction data from a specific highway construction project is used to illustrate the impact of unexpected schedule delays in increasing project GHG emissions. Next, a simulation based methodology is described to assess the effectiveness of alternative project management strategies in reducing GHG emissions. The contribution of this paper is that it explicitly considers projects emissions, in addition to cost and project duration, in developing project management strategies. Practical application of the method discussed in this paper will help construction firms reduce their project emissions through strategic project management, and without significant investment in new technology. In effect, this paper lays the foundation for best practices in construction management that will optimize project cost and duration, while minimizing GHG emissions.

Firing Up the Crucible with Senator Lee Metcalf & Governor Forrest Anderson -- Judge Gordon Bennett in “The Crucible of Change”

During the lead-up to Montana second progressive era, Lee Metcalf and Forrest Anderson, along with others, kept the progressive flame lit in Montana. Metcalf’s political history is replete with close electoral wins because of his commitment to progressive ideals when the times were not always politically favorable for that. As State Legislator, MT Supreme Court Justice, Congressman and eventually as US Senator, Lee won races by as little as 55 votes because he stuck to his guns as a progressive. In Forrest Anderson’s career as a County Attorney, State Legislator, MT Supreme Court Justice and 12 years as MT Attorney General he was respected as a pragmatic practitioner of politics. But during that entire career leading up to his election as Governor, Forrest Anderson was also a stalwart supporter of the progressive agenda exemplified by FDR and the New Deal, which brought folks out of the Great Depression that was brought on by the bad policies of the GOP and big business. As MT’s second progressive period began in 1965, the first important election was Senator Metcalf’s successful re-election battle in 1966 with the sitting MT Governor, Tim Babcock. And the progressive express was really ignited by the election of Forrest Anderson as Governor in 1968 after 16 years of Republican Governors in MT. Gordon Bennett played a rather unique role, being a confidant of Metcalf and Anderson, both who respected his wide and varied experience, his intellect, and his roots in progressivism beginning with his formative years in the Red Corner of NE Montana. Working with Senator Metcalf and his team, including Brit Englund, Vic Reinemer, Peggy McLaughlin, Betty Davis and Jack Condon among others, Bennett helped shape the progressive message both in Washington DC and MT. Progressive labor and farm organizations, part of the progressive coalition, benefitted from Bennett’s advice and counsel and aided the Senator in his career including the huge challenge of having a sitting popular governor run against him for the Senate in 1966. Metcalf’s noted intern program produced a cadre of progressive leaders in Montana over the years. Most notably, Ron Richards transitioned from Metcalf Intern to Executive Secretary of the Montana Democratic Party (MDP) and assisted, along with Bennett, in the 1966 Metcalf-Babcock race in a big way. As Executive Secretary Richards was critical to the success of the MDP as a platform for Forrest Anderson’s general election run and win in 1968. After Forrest’s gubernatorial election, Richards became Executive Assistant (now called Chief of Staff) for Governor Anderson and also for Governor Thomas Judge. The Metcalf progressive strain, exemplified by many including Richards and Bennett, permeated Democratic politics during the second progressive era. So, too, did the coalition that supported Metcalf and his policies. The progressivism of the period of “In the Crucible of Change” was fired up by Lee Metcalf, Forrest Anderson and their supporters and coalitions, and Gordon Bennett was in the center of all of that, helping fire up the crucible, setting the stage for many policy advancements in both Washington DC and Montana. Gordon Bennett’s important role in the 1966 re-election of Senator Lee Metcalf and the 1968 election of Governor Forrest Anderson, as well as his wide experience in government and politics of that time allows him to provide us with an insider’s personal perspective of those races and other events at the beginning of the period of progressive change being documented “In the Crucible of Change,” as well as his personal insights into the larger political/policy picture of Montana. Gordon Bennett, a major and formative player “In the Crucible of Change,” was born in the far northeast town of Scobey, MT in 1922. He attended school in Scobey through the eighth grade and graduated from Helena High School. After attending Carroll College for two years, he received his BA in economics from Carleton College in Northfield, MN. During a brief stint on the east coast, his daily reading of the New York Times (“best newspaper in the world at that time … and now”) inspired him to pursue a career in journalism. He received his MA in Journalism from the University of Missouri and entered the field. As a reporter for the Great Falls Tribune under the ownership and management of the Warden Family, he observed and competed with the rigid control of Montana’s press by the Anaconda Company (the Great Falls Tribune was the only large newspaper in Montana NOT owned by ACM). Following his intellectual curiosity and his philosophical bend, he attended a number of Farm-Labor Institutes which he credits with motivating him to pursue solutions to economic and social woes through the law. In 1956, at the age of 34, he received his Juris Doctorate degree from the Georgetown University Law Center in Washington, DC. Bennett’s varied career included eighteen years as a farmer, four years in the US Army during WWII (1942-46), two years as Assistant MT Attorney General (1957-59) with Forrest Anderson, three years in private practice in Glasgow (1959-61), two years as Associate Solicitor in the Department of Interior in Washington, DC (1961-62), and private law practice in Helena from 1962 to 1969. While in Helena he was an unsuccessful candidate for the Montana Supreme Court (1962) and cemented his previous relationships with Attorney General Forrest Anderson and US Senator Lee Metcalf. Bennett modestly refuses to accept the title of Campaign Manager for either Lee Metcalf (1966 re-election over the challenger, MT Republican Governor Tim Babcock) or Forrest Anderson (his 1968 election as Governor), saying that “they ran their campaigns … we were only there to help.” But he has been generally recognized as having filled that critical role in both of those critical elections. After Governor Anderson’s election in 1968, Bennett was appointed Director of the MT Unemployment Compensation Commission, a position from where he could be a close advisor and confidant of the new Governor. In 1971, Governor Anderson appointed him Judge in the most important jurisdiction in Montana, the 1st Judicial District in Helena, a position he held for seventeen years (1971-88). Upon stepping down from his judgeship, for twenty years (1988-2008) he was a law instructor, mediator and arbitrator. He currently resides in Helena with his wife, Norma Tirrell, former newspaper reporter and researcher/writer. Bennett has two adult children and four grandchildren.

Governor Forrest Anderson’s Leadership & Political Acumen -- Alec Hansen “In the Crucible of Change”

Montana Governor Forrest Anderson was perhaps the most experienced and qualified person ever to be elected as Governor of Montana. Having previously served as a county attorney, a member of the legislature, a Supreme Court Justice, and twelve years as Attorney General, Anderson roared to a large victory in 1968 over the Incumbent GOP Governor Tim Babcock. Though the progressive change period in Montana began a few years earlier, Anderson’s 1968 win catapulted progressive policy-making into the mainstream of Montana political and governmental affairs. He used his unique skills and leadership to craftily architect the reorganization of the executive branch which had been kept weak since statehood so that the peoples’ government would not be able to challenge corporations who so dominated Montana. Anderson, whose “Pay More, What For?” campaign slogan strongly separated him from Tim Babcock and the GOP on the sales tax issue, not only beat back the regressive sales tax in the 1968 election, but oversaw its demise at the polls in 1971, shaping politics in Montana for decades to come. Anderson also was a strong proponent of the concept of a new Montana Constitution and contributed strategically to its calling and passage. Anderson served only one term as Governor for health reasons, but made those four years a launch pad for progressive politics and government in Montana. In this film, Alec Hansen, Special Assistant to Governor Anderson, provides an insider’s perspective as he reflects on the unique way in which Governor Anderson got things done at this critical period “In the Crucible of Change.” Alec Hansen is best known in Montana political and governmental circles as the long-time chief of the Montana League of Cities and Towns, but he cut his teeth in public service with Governor Forrest Anderson. Alec was born in Butte in 1941, attended local schools graduating from Butte High in 1959. After several years working as a miner and warehouseman for the Anaconda Company in Butte, he attended UM and graduated in History and Political Science in 1966. He joined the U.S. Navy and served with amphibious forces in Vietnam. After discharge from the Navy in 1968, he worked as a news and sports reporter for The Montana Standard in Butte until in September of 1969 he joined Governor Anderson as a Special Assistant focused on press, communications and speech-writing. Alec has noted that drafts were turned into pure Forrest Anderson remarks by the man himself. He learned at the knee of “The Fox” for the rest of Anderson’s term and continued with Governor Tom Judge for two years before returning to Butte to work for the Anaconda Company as the Director of Communications for Montana operations. In 1978, after Anaconda was acquired by the Atlantic Richfield Company, Alec went to work in February for U.S. Senator Paul Hatfield in Washington D.C., leaving after Hatfield’s primary election loss in June 1978. He went back to work for Gov. Judge, remaining until the end of 1980. In 1981 Alec worked as a contract lobbyist and news and sports reporter for the Associated Press in Helena. In 1982, the Montana League of Cities and Towns hired him as Executive Director, a position he held until retirement in 2014. Alec and his wife Colleen, are the parents of two grown children, with one grandson.

Governor Tom Judge: Early Years - The Path to Becoming Montana's 18th Governor -- Sidney Armstrong, Larry Pettit & Kent Kleinkopf “In the Crucible of Change”

The dramatic period of progressive change in Montana that is documented "In the Crucible of Change" series really exploded with the election of Governors Forrest Anderson and Tom Judge. Anderson's single term saw the dispatching of the sales tax as an issue for a long period, the reorganization of the executive branch of state government and the revision of Montana's Constitution. As a former legislator, county attorney, Supreme Court justice, and Attorney General, Anderson brought unmatched experience to the governorship when elected. Tom Judge, although much younger (elected MT’s youngest governor at age 38 immediately following Anderson), also brought serious experience to the governorship: six years as a MT State Representative, two years as a MT State Senator, four years is Lieutenant Governor and significant business experience. The campaign and election of John F. Kennedy in 1960 spurred other young Americans to service, including Tom Judge. First elected in 1960, he rose rapidly through MT’s political-governmental hierarchy until he took over the governorship in time to implement many of the changes started in Governor Anderson’s term. But as a strong progressive leader in his own right, Governor Judge sponsored and implemented significant advancements of his own for Montana. Those accomplishments, however, are the subject of other films in this series. This film deals with Tom Judge’s early years – his rise to the governorship from when he returned home after college at Notre Dame and newspaper experience in Kentucky to his actual election in November 1972. That story is discussed in this episode by three major players in the effort, all directly involved in Tom Judge’s early years and path to the governorship: Sidney Armstrong, Larry Pettit and Kent Kleinkopf. Their recollections of the early Tom Judge and the period of his advancement to the governorship provide an insider’s perspective of the growth of this significant leader of the important period of progressive change documented “In the Crucible of Change.” Sidney Armstrong, President of Sidney Armstrong Consulting, serves on the board and as the Executive Director of the Greater Montana Foundation. Formerly Executive Director of the Montana Community Foundation (MCF), she has served on national committees and participated in national foundation initiatives. While at MCF, she worked extensively with MT Governors Racicot and Martz on the state charitable endowment tax credit and other endowed philanthropy issues. A member of MT Governor Thomas L. Judge’s staff in the 1970s, she was also part of Governor Brian Schweitzer’s 2004 Transition Team, continuing to serve as a volunteer advisor during his term. In the 1980s, Sidney also worked for the MT State AFL-CIO and the MT Democratic Party as well as working two sessions with the MT Senate as Assistant Secretary of the Senate and aide to the President. A Helena native, and great granddaughter of pioneer Montanans, Sidney has served on numerous nonprofit boards, and is currently a board member for the Montana History Foundation. Recently she served on the board of the Holter Museum of Art and was a Governor’s appointee to the Humanities Montana board. She is a graduate of the International School of Geneva, Switzerland and the University of Montana. Armstrong's Irish maternal immigrant great-grandparents, Thomas and Maria Cahill Cooney, came to Virginia City, MT in a covered wagon in 1865, looking for gold. Eventually, they settled on the banks of the Missouri River outside Helena as ranchers. She also has roots in Butte, MT, where her journalist father's family, both of whom were newspaper people, lived. Her father, Richard K. O’Malley, is also the author of a well-known book about Butte, Mile High, Mile Deep, recently re-published by Russell Chatham. She is the mother of four and the grandmother of eight. Dr. Lawrence K. Pettit (Larry Pettit) (b. 5/2/1937) has had a dual career in politics and higher education. In addition to being Montana’s first Commissioner of Higher Education (the subject of another film in this series); Pettit, of Lewistown, served as legislative assistant to U.S. Senators James E. Murray and Lee Metcalf, campaign manager, head of transition team and assistant to Montana Governor Thomas L. Judge; taught political science at The Pennsylvania State University (main campus), was chair of political science at Montana State University, Deputy Commissioner for Academic Programs at the Texas Higher Education Coordinating Board, Chancellor of the University System of South Texas (since merged with Texas A&M University), President of Southern Illinois University, and President of Indiana University of Pennsylvania from where he retired in 2003. He has served as chair of the Commission on Leadership for the American Council on Education, president of the National Association of (University) System Heads, and on many national and state boards and commissions in higher education. Pettit is author of “If You Live by the Sword: Politics in the Making and Unmaking of a University President.” More about Pettit is found at http://www.lawrencekpettit.com… Kent Kleinkopf of Missoula is co-founder of a firm with a national scope of business that specializes in litigation consultation, expert vocational testimony, and employee assistance programs. His partner (and wife of 45 years) Kathy, is an expert witness in the 27 year old business. Kent received a BA in History/Education from the University of Idaho and an MA in Economics from the University of Utah. The Kleinkopfs moved to Helena, MT in 1971 where he was Assistant to the Commissioner of State Lands (later Governor) Ted Schwinden. In early 1972 Kent volunteered full time in Lt. Governor Tom Judge’s campaign for Governor, driving the Lt. Governor extensively throughout Montana. After Judge was elected governor, Kent briefly joined the staff of Governor Forrest Anderson, then in 1973 transitioned to Judge’s Governor’s Office staff, where he became Montana’s first “Citizens’ Advocate.” In that capacity he fielded requests for assistance from citizens with concerns and information regarding State Agencies. While on the Governor’s staff, Kent continued as a travel aide with the governor both in Montana and nationally. In 1977 Kent was appointed Director of the MT Department of Business Regulation. That role included responsibility as Superintendent of Banking and Chairman of the State Banking Board, where Kent presided over the chartering of many banks, savings and loans, and credit unions. In 1981 the Kleinkopfs moved to Missoula and went into the business they run today. Kent was appointed by Governor Brian Schweitzer to the Board of the Montana Historical Society in 2006, was reappointed and continues to serve. Kathy and Kent have a daughter and son-in-law in Missoula.

Immunoglobulin M-enriched intravenous immunoglobulin inhibits classical pathway complement activation, but not bactericidal activity of human serum

Acute or even hyperacute humoral graft rejection, mediated by classical pathway complement activation, occurs in allo- and xenotransplantation due to preformed anti-graft antibodies. Intravenous immunoglobulin (IVIg) preparations can prevent complement-mediated tissue injury and delay hyperacute xenograft rejection. It is known that IgM-enriched IVIg (IVIgM) has a higher capacity to block complement than IVIgG. Different IVIgs were therefore tested for specificity of complement inhibition and effect on anti-bacterial activity of human serum. IVIgM-I (Pentaglobin), 12% IgM), IVIgM-II (IgM-fraction of IVIgM-I, 60% IgM), and three different IVIgG (all >95% IgG) were used. The known complement inhibitor dextran sulfate was used as control. Hemolytic assays were performed to analyze pathway-specificity of complement inhibition. Effects of IVIg on complement deposition on pig cells and Escherichia coli were assessed by flow cytometry and cytotoxicity as well as bactericidal assays. Complement inhibition by IVIgM was specific for the classical pathway, with IC50 values of 0.8 mg/ml for IVIgM-II and 1.7 mg/ml for IVIgM-I in the CH50 assay. Only minimal inhibition of the lectin pathway was seen with IVIgM-II (IC50 15.5 mg/ml); no alternative pathway inhibition was observed. IVIgG did not inhibit complement in any hemolytic assay. Classical pathway complement inhibition by IVIgM was confirmed in an in vitro xenotransplantation model with PK15 cells. In contrast, IVIgM did not inhibit (mainly alternative pathway mediated) killing of E. coli by human serum. In conclusion, IgM-enriched IVIg is a specific inhibitor of the classical complement pathway, leaving the alternative pathway intact, which is an important natural anti-bacterial defense, especially for immunosuppressed patients.

Hop-to-Hop Reliability in IP-Based Wireless Sensor Networks - A Cross-Layer Approach

To interconnect a wireless sensor network (WSN) to the Internet, we propose to use TCP/IP as the standard protocol for all network entities. We present a cross layer designed communication architecture, which contains a MAC protocol, IP, a new protocol called Hop-to-Hop Reliability (H2HR) protocol, and the TCP Support for Sensor Nodes (TSS) protocol. The MAC protocol implements the MAC layer of beacon-less personal area networks (PANs) as defined in IEEE 802.15.4. H2HR implements hop-to-hop reliability mechanisms. Two acknowledgment mechanisms, explicit and implicit ACK are supported. TSS optimizes using TCP in WSNs by implementing local retransmission of TCP data packets, local TCP ACK regeneration, aggressive TCP ACK recovery, congestion and flow control algorithms. We show that H2HR increases the performance of UDP, TCP, and RMST in WSNs significantly. The throughput is increased and the packet loss ratio is decreased. As a result, WSNs can be operated and managed using TCP/IP.

Pathways to care in subjects at high risk for psychotic disorders — A European perspective

Evidence-based decisions on indicated prevention in early psychosis require large-scale studies on the pathways to care in high-risk subjects. EPOS (The European Prediction of Psychosis Study), a prospective multi-center, naturalistic field study in four European countries (Finland, Germany, The Netherlands and England), was designed to acquire accurate knowledge about pathways to care and delay in obtaining specialized high risk care. Our high risk sample (n=233) reported on average 2.9 help-seeking contacts, with an average delay between onset of relevant problems to initial help-seeking contact of 72.6 weeks, and between initial help-seeking contact and reaching specialized high risk care of 110.9 weeks. This resulted in a total estimated duration of an unrecognized risk for psychosis of 3 ½ years. Across EPOS EU regions, about 90% of care pathway contacts were within professional health care sectors. Between EPOS regions, differences in the pathways parameters including early detection and health-care systems were often very pronounced. High-risk participants who later made transition to a full psychotic disorder had significantly longer delays between initial help-seeking and receiving appropriate interventions. Our study underlines the need for regionally adapted implementation of early detection and intervention programs within respective mental health and health care networks, including enhancing public awareness of early psychosis.

Plötzlicher Tod infolge eines persistierenden Ductus arteriosus. Fall eines 4 Tage alt gewordenen Säuglings

Ein persistierender Ductus arteriosus (Ductus Botalli) ist seit Jahren als Ursache eines plötzlichen und unerwarteten Neugeborenentods und pulmonaler Hämorrhagien identifiziert. Insbesondere Frühgeborene weisen ein erhöhtes Risiko zur Entwicklung eines hämodynamisch signifikanten persistierenden Ductus arteriosus auf. Vorgestellt wird der plötzliche und unerwartete Todesfall eines 4 Tage alt gewordenen Säuglings, der 2 Wochen vor dem errechneten Termin geboren worden war. Bei der Obduktion zeigte sich ein sehr muskelkräftiger arterieller Gefäßkurzschluss zwischen der A. pulmonalis und dem Aortenbogen mit einem Durchmesser knapp unter dem der A. pulmonalis. Als Folge der pulmonalen Hyperperfusion fanden sich eine massive akute Blutstauung und kongestives Herzversagen infolge des „shunting“ von der systemischen in die pulmonale Zirkulation.

Ptychographic reconstruction of attosecond pulses

We demonstrate a new attosecond pulse reconstruction modality which uses an algorithm that is derived from ptychography. In contrast to other methods, energy and delay sampling are not correlated, and as a result, the number of electron spectra to record is considerably smaller. Together with the robust algorithm, this leads to a more precise and fast convergence of the reconstruction.
