Property as an economic concept: Reconciling legal and economic conceptions of property rights in a Coasean framework

Adopting a simplistic view of Coase (1960), most economic analyses of property rightsdisregard both the key advantage that legal property rights (that is, in rem rights) provide torightholders in terms of enhanced enforcement, and the difficulties they pose to acquirers interms of information asymmetry about legal title. Consequently, these analyses tend to overstatethe role of "private ordering" and disregard the two key elements of property law: first, theessential conflict between property (that is, in rem) enforcement and transaction costs; and,second, the institutional solutions created to overcome it, mainly contractual registries capable ofmaking truly impersonal (that is, asset-based) trade viable when previous relevant transactionson the same assets are not verifiable by judges. This paper fills this gap by reinterpreting bothelements within the Coasean framework and thus redrawing the institutional foundations of bothproperty and corporate contracting.

Os Liames de Solidariedade entre o Estado e as Organizações de Economia Solidária na Luta contra Pobreza nas Comunidades Rurais em Cabo Verde

La thèse a comme but comprendre, à la lumière du paradigme du don et de la perspective théorique de l’économie solidaire, la nature des relations de coopération entre l’Etat et les Associations Communautaires de Développement, dans le cadre de la lutte contre la pauvreté dans les communautés rurales au Cap Vert. L’objet principal de l’étude est le Programme de la Lutte Contre la Pauvreté et, particulièrement, son (Sous)Programme de la Lutte Contre la Pauvreté au milieu rural. Le PLPR, par sa conception de pauvreté, méthodologie et stratégie d’intervention décentralisé au sein des Associations Communautaires de Développement et respectives communautés, s’est révélé comme le modèle qui illustre mieux comment les deux modalités de solidarité démocratique, réciprocité et redistribution, s’interragent et participent d’un processus dynamique de génération, construction et multiplication d’initiatives et d’expériences d’économie solidaires; d’ampliation et approfondissement du processus de démocratisation de l’Etat et d’approximation de la gestion publique des communautés rurales pauvres. Subsidiairement, le paradigme du don, particulièrement, le concept de solidarité démocratique, nous a forcé à proposer un autre regard sur l’économie (conventionnelle) du Cap Vert, à partir de la réflexion et analyse sur la relation entre l’Etat et la diaspora capverdienne, propagée autour du monde, comme hypothèse dont les liens culturelles et d’identités qui existent entre l’Etat et la Diaspora constituent la motivation principale des émigrants pour envoyer, régulièrement, leurs revenues au Cap Vert. De son côté, à partir des relations de coopération entre l’Etat capverdien et ses traditionnels partenaires internationaux de développement, nous avons formulé l’hypothèse dont l’Aide Publique au Développement consiste en un système international de redistribution de ressources publiques au Cap Vert, (dons aux étrangers), pour faire face aux défis de la lutte pour l’éradication de la pauvreté et de la promotion du développement socioéconomique, représentant ainsi, comme l’équivalent empirique du concept de solidarité distributive international.

Iowa Values Fund and Business Assistance Programs 2007 Annual Report, 2007

Following is the 2007 Annual Report of the Iowa Values Fund (IVF 2005) and Business Assistance Programs covering activity during Fiscal Year 2007 (FY ‘07) and cumulative for the first four years of the Iowa Values Fund Programs. The IVF (2005) is the primary funding source for a menu of financial assistance programs the Iowa Department of Economic Development (IDED) offers as incentives to Iowa companies to expand here, to recruit new companies into Iowa and assist new entrepreneurial ventures. In addition to IDED the law appropriates IVF (2005) funds for economic development activities to the Board of Regents, the Departments of Cultural Affairs and Natural Resources and to Community Colleges for certain workforce training programs. In addition to the IVF (2005), IDED allocates a portion of Community Development Block Grant and Federal Emergency Stimulus funds and several tax credit programs, all of which are included in this report.

Federal AIP Funding For Iowa’s NPIAS Airports 2004-2007, September 13, 2004

Vision 100, the Century of Aviation Reauthorization Act, reauthorizes federal aviation programs through fiscal year 2007 and sets spending levels for the Airport Improvement Program (AIP), Essential Air Service, Small Community Development Grants, and other programs that develop and maintain facilities at airports around the country. A major component of the bill is the Airport Improvement Plan (AIP) program, which provides funding for airport rehabilitation and development projects.

Executive Summary, Feasibility Report on Proposed Amtrak Service Quad Cities-Chicago, January 7, 2008

Since the introduction of expanded levels of intrastate service on October 30, 2006, Amtrak trains in Illinois have produced impressive gains in both ridership and ticket revenue. This success and continuing stakeholder support has given rise to a formal request from the Illinois Department of Transportation (“Ill. DOT”) to Amtrak to develop a feasibility study regarding possible service consisting of a morning and an evening train in each direction between Chicago and the Quad Cities. The area between Chicago and the Quad Cities includes many rapidly growing communities. From Chicago toward the West and South, many towns and cities have experienced double digit growth increases in population since the year 2000. Southern DuPage, Cook and Will counties have seen especially strong growth, pressuring highway infrastructure, utilities, and schools. Community development and highway congestion are readily apparent when traveling the nearly 3 hour, 175 mile route between Chicago and the Quad Cities. As information, there are only three weekday round trip bus frequencies available between Chicago and the Quad Cities. The Quad City International Airport offers a total of 10 daily scheduled round trip flights to Chicago's O'Hare International Airport via two separate carriers flying regional jets. The Quad Cities (Davenport, Moline, Rock Island, and Bettendorf) are located along the Mississippi River. Nearly 60% of its visitors are from the Chicago area. With dozens of miles of scenic riverfront, river boating, casinos, and thousands of acres of expansive public spaces, the Quad Cities area is a major draw from both Iowa and Illinois. The huge Rock Island Arsenal, one of the largest military arsenals in the country and located along the river, is transitioning to become the headquarters of the United States First Army. As will be discussed later in the report, there is only one logical rail route through the Quad Cities themselves. The Iowa Interstate Railroad operates through the Quad Cities along the river and heads west through Iowa. The Quad Cities are considering at least three potential locations for an Amtrak station. A study now underway supported by several local stakeholders will recommend a site which will then be considered, given available local and other financial support. If Amtrak service were to terminate in the Quad Cities, an overnight storage track of sufficient length along with ample parking and certain other requirements covered elsewhere in the report would be required.

Saberes de mujeres. Legitimización del conocimiento masculino

La asignación de unas categorías de desvalorización hacia profesiones relacionadas con el cuidar debido a la reproducción de tareas tradicionalmente desarrolladas en el ámbito privado y doméstico, tiene que ver con la configuración de un orden social masculino, que ha necesitado de un proceso de deslegitimización y silenciamiento a lo largo de la historia de las aportaciones realizadas por las mujeres y que ha necesitado configurar unos supuestos arbitrarios basados en la biología, para justificar su exclusión. La monopolización del mercado sanitario y su control por la medicina a traves de la creación de instituciones con capacidad para legitimar los saberes y transmitirlos, ha permitido dejar fuera del conocimiento científico ciertas prácticas de curación, como las de las enfermeras y comadronas. Se hace por tanto necesario rescribir la historia para recuperar del olvido mujeres y profesiones que a pesar de haber hecho contribuciones destacables, no aparecen en la historia oficial y que han estado relegadas del conocimiento debido a intereses de poder y control. Dado que la ciencia no es neutral, es necesario visibilizar las estrategias que utiliza para la reproducción y supervivencia de los supuestos en que se apoya el sistema de clasificación social.

El voluntariat social i la participació comunitària : la situació actual i les perspectives de futur al voltreganès

Aquest Treball de Final de Grau d’Educació Social pretén aprofundir i reflexionar al voltant dels conceptes de desenvolupament comunitari, participació i voluntariat social, sobretot en la seva dimensió pràctica. Partint d’aquest marc teòric, s’ha portat a terme una anàlisi de la realitat social i una diagnosi de necessitats socials del Voltreganès, és a dir, de la comunitat que formen els municipis de les Masies de Voltregà i Sant Hipòlit de Voltregà. A partir dels resultats, i la interpretació de les dades extretes de les entrevistes, realitzades a diferents professionals vinculats amb l’àmbit social i d’atenció a les persones, s’ha justificat la necessitat i interès d’un projecte de voluntariat, per poder donar resposta a les necessitats emergents de la població. En la part final del treball presento l’àmbit i les línies principals d’aquest projecte.

Runkoelementtitehtaan materiaalitoimintojen kehittäminen prosessiajattelun näkökulmasta

Työn tavoitteena on ollut selvittää runkoelementtitehtaan materiaalien hankinnanorganisointi ja ohjaus nykytilanteessa. Tutkimuksessa on pyritty löytämään materiaaliprosessin kannalta toimintaa rajoittavia pullonkauloja sekä etsitty kehitystoimenpiteitä ongelmakohtiin prosessiajattelun näkökulmasta. Tarkastelun kohteena on ollut yrityksen operatiivinen materiaaliprosessi nimikkeiden tilauksesta varastointiin. Työssä on käytetty kvalitatiivista tutkimusmenetelmää ja empiirisen osuuden tiedot on hankittu haastatteluilla ja laatuohjeistuksesta. Yrityksen nykytilanne on mallinnettu prosessikaavioiden avulla, ja on selvitetty mitkä ovat prosessin tieto- ja materiaalivirrat sekä mitkä ovat tärkeimmät toiminnot materiaaliketjussa. Prosessianalyysin ja haastatteluiden pohjalta määriteltiin kehitysehdotukset prosessin suorituskyvyn tehostamiseksi. Nykytilan kartoituksen jälkeen suurimmat ongelmat materiaaliprosessissa liittyvät tilausten ajoitusten hallintaan, muutoksien vaikutukseen prosessissa sekä vastuiden ja kokonaishallinnan puuttumiseen. Ongelmat johtuvat pääosin rakennusalan projektimaisesta luonteesta. Yhdeksi kehityskohteeksi nousi myös tiedonhallinnan tehostaminen, etenkin prosessin vaiheiden automatisointi tietojärjestelmiä hyödyntäen. Toimintaan on pyritty etsimään ratkaisuja prosessiajattelun avulla, mikä osoittautui sopivaksi menetelmäksi toiminnan kehittämisessä. Tutkimuksen tuloksena syntyi kehitysehdotuksia, joiden pohjalta muodostettiin uusi materiaalien ohjauksen toimintamalli. Toimintamallissa tärkeimpänä on ennakkotiedon hyödyntäminen tilaussuunnittelun tukena. Alustavat materiaalimäärät välitetään ennakkotietona myös toimittajille, jotka voivat paremmin suunnitella omaa tuotantokapasiteettiaan. Tilausten suunnittelu tapahtuu tarkentuvasti ja lopullinen materiaalimäärä ja tarveajankohta välitetään kotiinkutsun yhteydessä. Toimintamalliin liittyy lisäksi materiaalien vastaanoton ja varastoinnin kehittäminen sekä muutoksien hallinta tietojärjestelmää paremmin hyödyntäen. Kriittisintä materiaaliprosessissa tulee olemaan prosessin tiedonhallinta ja siihen liittyvät vastuukysymykset.

Quantitative TCR:pMHC Dissociation Rate Assessment by NTAmers Reveals Antimelanoma T Cell Repertoires Enriched for High Functional Competence.

Experimental models demonstrated that therapeutic induction of CD8 T cell responses may offer protection against tumors or infectious diseases providing that T cells have sufficiently high TCR/CD8:pMHC avidity for efficient Ag recognition and consequently strong immune functions. However, comprehensive characterization of TCR/CD8:pMHC avidity in clinically relevant situations has remained elusive. In this study, using the novel NTA-His tag-containing multimer technology, we quantified the TCR:pMHC dissociation rates (koff) of tumor-specific vaccine-induced CD8 T cell clones (n = 139) derived from seven melanoma patients vaccinated with IFA, CpG, and the native/EAA or analog/ELA Melan-A(MART-1)(26-35) peptide, binding with low or high affinity to MHC, respectively. We observed substantial correlations between koff and Ca(2+) mobilization (p = 0.016) and target cell recognition (p < 0.0001), with the latter independently of the T cell differentiation state. Our strategy was successful in demonstrating that the type of peptide impacted on TCR/CD8:pMHC avidity, as tumor-reactive T cell clones derived from patients vaccinated with the low-affinity (native) peptide expressed slower koff rates than those derived from patients vaccinated with the high-affinity (analog) peptide (p < 0.0001). Furthermore, we observed that the low-affinity peptide promoted the selective differentiation of tumor-specific T cells bearing TCRs with high TCR/CD8:pMHC avidity (p < 0.0001). Altogether, TCR:pMHC interaction kinetics correlated strongly with T cell functions. Our study demonstrates the feasibility and usefulness of TCR/CD8:pMHC avidity assessment by NTA-His tag-containing multimers of naturally occurring polyclonal T cell responses, which represents a strong asset for the development of immunotherapy.

O centenário da Teoria de Bohr

The year 2013 marks the centennial of that wondrous year in which Niels Bohr proposed a novel theory about the constitution of atoms and small molecules after which the way we regard atoms and their behaviour began to be drastically altered. Bohr drew on several sources for his original description of the atoms, most importantly on spectroscopy and Balmer's equation thereof, the new quantum hypothesis advanced a few years earlier by Planck, and the planetary atom proposed by Rutherford. Although Bohr's ideas were to be eventually overtaken by the advent of quantum mechanics, his theory was the basis of a new thinking about atoms and molecules which constitutes an invaluable asset in the development of science ever since.
