The role of title insurance under recording and registration

This article outlines a transaction cost theory of title insurance andanalyses the role it plays in countries with recording and registrationof land titles. Title insurance indemnifies real estate right holdersfor losses caused by pre-existing title defects that are unknown whenthe policy is issued. It emerged to complement the errors and omissions insurance of professionals examining title quality. Poor organizationof public records led title insurers in the USA to integrate titleexamination and settlement services. Their residual claimant statusmotivates insurers to screen, cure and avoid title defects. Firmsintroducing title insurance abroad produce little information on titlequality, however. Their policies are instead issued on a casualty basis,complementing and enforcing the professional liability of conveyancers.Future development in markets with land registration is uncertainbecause of adverse selection, competitive reactions from establishedconveyancers and the ability of larger banks to self-insure title risks.

L' univers femení del Jaufré : les dames, motor de l'acció cavalleresca

Els models literaris analitzats se centren quasi exclusivament en les obres de Chrétien de Troyes i en els lais de Maria de França. S'ha pretés en tot moment fer una lectura de la novel·la en clau femenina per tal de demostrar que la figura central de l'heroi actua i evoluciona generalment gràcies a o a causa de la voluntat, les decisions o les accions de les dones que troba en la seua aventura. No hi pot haver cavalleria sense amor; tot cavaller ha de lluitar per la seua dama tant al camp de batalla com a la cort.

L'adquisició de l'entonació en català, castellà i anglès

El principal objectiu del projecte és analitzar el desenvolupament de l’entonació de tres llengües, el català, el castellà i l’anglès. Pretenem investigar el desenvolupament dels diferents patrons entonatius que trobem en la producció primerenca, avaluant si, efectivament, aquests primers contorns produïts pels nens reflecteixen o no les propietats prosòdiques específiques de la llengua input dels adults. En resum, l'objectiu és poder esbrinar com l'infant va configurant la seva gramàtica entonativa així com el significat que va associat a aquestes produccions entonatives. Pretenem analitzar dos tipus de dades. Per una banda, un corpus d’entonació que conté els diàlegs controlats entre 36 nens i 36 adults (12 nens de cada llengua de 2, 4 i 6 anys) i que permet de comparar les mateixes frases produïdes pels adults i pels nens. Per altra banda, els corpus longitudinals de CHILDES que ens permeten analitzar dades sobre actes de parla i formes entonatives (corpus Serra-Solé per al català, corpus Ornat i Llinàs-Ojea per al castellà i el corpus Providence per a l'anglès americà i el Forrester per a l'anglès britànic).

Web services to link interlibrary software with OCLC WorldShare

Purpose - This article describes the use of web services to interconnect the GTBib interlibrary loan program with the OCLC WorldShare platform. Design/methodology/approach - We describe the current problem of duplication of procedures in libraries that have added their collections to the OCLC WorldCat catalogue in recent years and are therefore more likely to receive interlibrary loan requests through the WorldShare Platform. Findings - A solution that uses web services to insert and retrieve requests between the two systems is presented. Autonomous agents periodically check the status of the requests and keep them updated and synchronized. These agents also inform the library staff of any variation or inconsistency that is detected. Practical Implications - This technology reduces process management time by making it unnecessary to introduce the request data in both systems. Agents are used to check the consistency of statuses between the two systems, thus avoiding errors and omissions and improving the efficiency of the whole interlibrary loan process. Originality/value - This paper describes in detail the technical aspects of the solution as a reference for the development of future applications.

Argument omissions in preschool Catalan and Spanish speaking children with SLI

El presente artículo describe tres estudios sobre la producción del verbo y la estructura argumental en niños con Trastorno Específico del Lenguaje (TEL) usando diferentes metodologías. El primero es un estudio observacional que usa una muestra de habla espontánea. El segundo usa una tarea experimental de denominación de oraciones como resultado de la observación de videos de acciones. El tercero comprende la tarea de denominación de oraciones con imágenes estáticas en eventos con diferente complejidad argumental. Aunque los datos concretos varían en función de la metodología usada, hay una clara evidencia de que los niños de habla catalana y española con TEL presentan especiales dificultades en la producción de verbos con una alta complejidad en relación a la estructura argumental y cometen errores en la especificación de los argumentos obligatorios. Se concluye quetanto limitaciones en el procesamiento como déficits en la representación semántica de los verbos pueden estar implicados en estas dificultades

Limitations and biases of conventional analysis of climate change. Towards an analysis coherent with sustainable development

This paper shows the numerous problems of conventional economic analysis in the evaluation of climate change mitigation policies. The article points out the many limitations, omissions, and the arbitrariness that have characterized most evaluation models applied up until now. These shortcomings, in an almost overwhelming way, have biased the result towards the recommendation of a lower aggressiveness of emission mitigation policies. Consequently, this paper questions whether these results provide an appropriate answer to the problem. Finally, various points that an analysis coherent with sustainable development should take into account are presented.

Economic rationality and ethical behavior

This paper argues that economic rationality and ethical behavior cannotbe reduced one to the other, casting doubts on the validity of formulaslike 'profit is ethical' or 'ethics pays'. In order to express ethicaldilemmas as opposing economic interest with ethical concerns, we proposea model of rational behavior that combines these two irreducible dimensions in an open but not arbitrary manner. Behaviors that are neither ethicalnor profitable are considered irrational (non-arbitrariness). However,behaviors that are profitable but unethical, and behaviors that are ethicalbut not profitable, are all treated as rational (openness). Combiningethical concerns with economic interest, ethical business is in turn anoptimal form of rationality between venality and sacrifice.Because every one prefers to communicate that he acts ethically, ethicalbusiness remains ambiguous until some economic interest is actuallysacrificed. We argue however that ethical business has an interest indemonstrating its consistency between communication and behavior by atransparent attitude. On the other hand, venal behaviors must remainconfidential to hide the corresponding lack of consistency. Thisdiscursive approach based on transparency and confidentiality helpsto further distinguish between ethical and unethical business behaviors.

Trade-off between formal and informal care in Spain

The remarkable growth of older population has moved long term care to the front ranks of the social policy agenda. Understanding the factors that determine the type and amount of formal care is important for predicting use in the future and developing long-term policy. In this context we jointly analyze the choice of care (formal, informal, both together or none) as well as the number of hours of care received. Given that the number of hours of care is not independent of the type of care received, we estimate, for the first time in this area of research, a sample selection model with the particularity that the first step is a multinomial logit model. With regard to the debate about complementarity or substitutability between formal and informal care, our results indicate that formal care acts as a reinforcement of the family care in certain cases: for very old care receivers, in those cases in which the individual has multiple disabilities, when many care hours are provided, and in case of mental illness and/or dementia. There exist substantial differences in long term care addressed to younger and older dependent people and dependent women are in risk of becoming more vulnerable to the shortage of informal caregivers in the future. Finally, we have documented that there are great disparities in the availability of public social care across regions.

Should banking supervision and monetary policy tasks be given to different agencies?

This paper adds some new arguments to the thesis that the responsibility forbanking supervision should be assigned to an agency formally separated bythe Central bank. We also provide some additional evidence on the macroand microeconomic performance of OECD countries whose banking systems areclassified according to the regulatory regime in place. We find that theinflation rate is considerably higher and more volatile in countries wherethe Central bank acts as a monopolist in banking supervision. Besides,although banks seem to be more profitable when Central banks supervise them,they incur into higher costs and rely more on deposits with respect to moresophisticated liabilities as a funding source.The data are not definitively in favor of functional separation. However, we argue that the evolution of financial intermediaries, moral hazard problems and especially cost accountability seem to suggest that separation would be a better solution for industrialized countries.We also critically discuss the current arrangement of financial regulationand supervision in the EMU: our proposal is to establish an independentEuropean System of Financial Supervisors (ESFS) structured similarly to theESCB.

Insurance and safety after September 11, 2001: Coming to grips with the costs and threats of terrorism

This chapter, originally written as a consequence of the terrorist attacksof September 11, 2001, provides an elementary, everyday introduction tothe concepts of risk and insurance. Conceptually, risk has two dimensions:a potential loss, and the chance of that loss being realized. People can,however, transfer risk to insurance companies against the payment ofso-called premiums. In practice, however, one needs accurate assessmentsof both losses and probabilities to judge whether premiums are appropriate.For many risks, this poses little problem (e.g., life insurance); however,it is difficult to assess risks of many other kinds of events such as actsof terrorism. It is emphasized, that through evolution and learning, peopleare able to handle many of the common risks that they face in life. Butwhen people lack experience (e.g., new technologies, threats of terrorism),risk can only be assessed through imagination. Not surprisingly, insurancecompanies demand high prices when risks are poorly understood. In particular,the cost of insurance against possible acts of terrorism soared afterSeptember 11. How should people approach risk after the events of that day?Clearly, the world needs to protect itself from the acts of terrorists andother disturbed individuals. However, it is also important to address the root causes of such antisocial movements. It is, therefore, suggested thatprograms addressed at combatting ignorance, prejudice, and socialinequalities may be more effective premiums for reducing the risk ofterrosrtism than has been recognized to date.

ß-Catenin Regulation during the Cell Cycle: Implications in G2/M and Apoptosis

ß-catenin is a multifunctional protein involved in cell-cell adhesion and Wnt signal transduction. ß-Catenin signaling has been proposed to act as inducer of cell proliferation in different tumors. However, in some developmental contexts and cell systems ß-catenin also acts as a positive modulator of apoptosis. To get additional insights into the role of ß-Catenin in the regulation of the cell cycle and apoptosis, we have analyzed the levels and subcellular localization of endogenous ß-catenin and its relation with adenomatous polyposis coli (APC) during the cell cycle in S-phase¿synchronized epithelial cells. ß-Catenin levels increase in S phase, reaching maximum accumulation at late G2/M and then abruptly decreasing as the cells enter into a new G1 phase. In parallel, an increased cytoplasmic and nuclear localization of ß-catenin and APC is observed during S and G2 phases. In addition, strong colocalization of APC with centrosomes, but not ß-catenin, is detected in M phase. Interestingly, overexpression of a stable form of ß-catenin, or inhibition of endogenous ß-catenin degradation, in epidermal keratinocyte cells induces a G2 cell cycle arrest and leads to apoptosis. These results support a role for ß-catenin in the control of cell cycle and apoptosis at G2/M in normal and transformed epidermal keratinocytes.

Citizens' control and the efficiency of local public services

Està àmpliament acceptat que la descentralització fiscal incrementa el control dels ciutadans sobre els polítics, fomenta el rendiment de comptes i augmenta l¿eficiència. Aquest treball té per objectiu identificar les característiques socio-econòmiques dels ciutadans (votants potencials) que generen un major control sobre els responsables polítics locals provocant, així, un major nivell d'eficiència en un context descentralitzat.També s'analitzen les característiques fiscals dels governs locals que fomenten aquest control i eficiència. L'estudi s'ha aplicat a una mostra de municipis catalans seguint la metodologia convencional basada en l'estimació en dues etapes. A la primera etapa s'estima l'eficiència en que operen els municipis mitjançant la tècnica DEA. La novetat rau en el càlcul d'una nova versió d'indicador global d¿output municipal. En la segona etapa, a través d¿una estimació tipus Tobit (models censurats) i de mètodes bootstrap, es mostra com els factors abans comentats poden influir sobre l¿eficiència. Els resultats suggereixen que la forta presencia de comerciants, jubilats i persones amb dret a vot afavoreixen el control dels ciutadans, el rendiment de comptes i l¿eficiència. Un factor que facilita aquest control, i per tant una major eficiència, és la presència de baixos costos d'oportunitat d'obtenir informació sobre la gestió local dels serveis públics.

Dynamical properties of discrete breathers in curved chains with first and second neighbor interaction

We present the study of discrete breather dynamics in curved polymerlike chains consisting of masses connected via nonlinear springs. The polymer chains are one dimensional but not rectilinear and their motion takes place on a plane. After constructing breathers following numerically accurate procedures, we launch them in the chains and investigate properties of their propagation dynamics. We find that breather motion is strongly affected by the presence of curved regions of polymers, while the breathers themselves show a very strong resilience and remarkable stability in the presence of geometrical changes. For chains with strong angular rigidity we find that breathers either pass through bent regions or get reflected while retaining their frequency. Their motion is practically lossless and seems to be determined through local energy conservation. For less rigid chains modeled via second neighbor interactions, we find similarly that chain geometry typically does not destroy the localized breather states but, contrary to the angularly rigid chains, it induces some small but constant energy loss. Furthermore, we find that a curved segment acts as an active gate reflecting or refracting the incident breather and transforming its velocity to a value that depends on the discrete breathers frequency. We analyze the physical reasoning behind these seemingly general breather properties.

Open inflation and the singulary boundary

The singularity in the Hawking-Turok model of open inflation has some appealing properties, such as the fact that its action is integrable. Also, if one thinks of the singularity as the boundary of spacetime, then the Gibbons-Hawking term is nonvanishing and finite. Here, we consider a model where the gravitational and scalar fields are coupled to a dynamical membrane. The singular instanton can then be obtained as the limit of a family of no-boundary solutions where both the geometry and the scalar field are regular. Using this procedure, the contribution of the singularity to the Euclidean action is just 1/3 of the Gibbons-Hawking term. Unrelated to this issue, we also point out that the singularity acts as a reflecting boundary for scalar perturbations and gravity waves. Therefore, the quantization of cosmological perturbations seems to be well posed in this background.
