Academic literature on the topic 'References point'

This master‘s thesis is formed as a part of the research project for whose analyse is used the worldwide experimental network called PlanetLab. The whole dilemma is engaged by IPTV technology. IPTV is a protocol that makes possible transfer data of a television content over the Internet to the end user. In the IPTV technology the server is a source. These data are presented as a video and audio signal (streem) which are required to deliver to the end users. Some structure, which presents alternate these computers´connection, has been established, because the technology making use of the big pretention is used. The most patent way between the source and the destination is found. My objective is design this structure in the pursuit. The principle of the signal ramification from one node to several nodes (in group) is called multicast. Rather said from one node to the set of nodes. In the IPTV is presented each one single program for one multicast group. The concrete end users (recipients) are members of one or several obtainable multicast groups. The switch between programs demands a change from one multicast group to other group. For an analyse is used the worldwide experimental network called PlanetLab. This network was created after the floatation of three American´s universities in 2002. Nowadays it takes in more than 800 nodes which are distributed over the world. The PlanetLab is used by multinational company such as the Intel or the Hewlett-Packard. It is created for the testing and the scientific scope. I make the scripts in the Linux for the formation of the interconnecting structure. The main item by the course of the unreeling is response time. I investigate it with a command called “ping”. Everything is created in the Linux because all nodes use the operation system Linux in PlanetLab. By the help of the command “ping” I take the active nodes and response times. According to the response time I make a distance vectors which are used for the finding a location in the face of the references points which were determined before. According to the similarity of these vectors is designated to what end point is put to the point.

It is well-established that, when confronted with a decision to be taken under risk, individuals use reference payoff levels as important inputs. The purpose of this paper is to study which reference points characterize decisions in a setting in which there are several plausible reference levels of payoff. We report an experiment, in which we investigate which of four potential reference points: (1) a population average payoff level, (2) the announced expected payoff of peers in a similar decision situation, (3) a historical average level of earnings that others have received in the same task, and (4) an announced anticipated individual payoff level, best describes decisions in a decontextualized risky decision making task. We find heterogeneity among individuals in the reference points they employ. The population average payoff level is the modal reference point, followed by experimenter's stated expectation of a participant's individual earnings, followed in turn by the average earnings of other participants in previous sessions of the same experiment. A sizeable share of individuals show multiple reference points simultaneously. The reference point that best fits the choices of the individual is not affected by a shock to her income.

Presentación realizada en el marco de las VI Jornadas Nacionales de Bibliotecas Universitarias:"REDESCUBRIENDO LA EDUCACIÓN SUPERIOR EN LA ERA DEL CONOCIMIENTO", realizado 28-30 de Mayo del 2014, Lima. Perú.<br>Los Centros de Información de la Universidad de Peruana de Ciencias Aplicadas (UPC) implementan el Servicio de referencia virtual, a través de la plataforma Question Point, en el año 2009, con el soporte tecnológico de OCLC (Online Computer Library Center) y ante la necesidad de los usuarios que demandaban un canal de comunicación online, que les permita realizar sus consultas académicas, referentes a los servicios que ofrecen los Centros de información. La implementación de este servicio ha permitido atender hasta la fecha 6534 consultas vía email (formulario web) y chat, lo que no solo ha servido para satisfacer las consultas de los usuarios sino también para formarlos en estrategias de búsquedas y en el uso correcto de los servicios físicos y digitales que ofrecemos a la comunidad universitaria. A partir del año 2011, se integra un Qwidget de chat del Question Point en el Aula Virtual de los alumnos, debido a que se identifica a esta última, como el ambiente virtual más utilizado por los alumnos, al consultar los materiales de enseñanza de sus cursos. Esta estrategia tiene como finalidad que los alumnos puedan encontrar en su principal medio de interacción virtual, una nueva alternativa de comunicación con los Centros de Información, para la resolución de sus consultas referentes a la búsqueda de fuentes de información bibliográfica así como también para solicitar orientación en el uso de los distintos servicios que se ofrecen. Esta estrategia ha dado como resultado que en el año 2013 el número de consultas vía chat se incremente en un 73% respecto al año 2011. Asimismo, cabe resaltar que en promedio el 59% de las consultas vía chat son realizadas desde el Qwidget insertado en el Aula Virtual. Finalmente, un dato resaltante es que el 74% de las consultas recibidas son a través del canal del chat, lo cual indica que existe una marcada tendencia de los usuarios al uso de estos servicios, por lo que se recomienda a otras áreas de la universidad, tomar esta experiencia como modelo para la atención de las consultas que reciben de sus usuarios.

Uno dei problemi più importanti della 3D Computer Vision è il cosiddetto surface matching, che consiste nel trovare corrispondenze tra oggetti tridimensionali. Attualmente il problema viene affrontato calcolando delle feature locali e compatte, chiamate descrittori, che devono essere riconosciute e messe in corrispondenza al mutare della posa dell'oggetto nello spazio, e devono quindi essere invarianti rispetto all'orientazione. Il metodo più usato per ottenere questa proprietà consiste nell'utilizzare dei Local Reference Frame (LRF): sistemi di coordinate locali che forniscono un'orientazione canonica alle porzioni di oggetti 3D che vengono usate per calcolare i descrittori. In letteratura esistono diversi modi per calcolare gli LRF, ma fanno tutti uso di algoritmi progettati manualmente. Vi è anche una recente proposta che utilizza reti neurali, tuttavia queste vengono addestrate mediante feature specificamente progettate per lo scopo, il che non permette di sfruttare pienamente i benefici delle moderne strategie di end-to-end learning. Lo scopo di questo lavoro è utilizzare un approccio data-driven per far imparare a una rete neurale il calcolo di un Local Reference Frame a partire da point cloud grezze, producendo quindi il primo esempio di end-to-end learning applicato alla stima di LRF. Per farlo, sfruttiamo una recente innovazione chiamata Spherical Convolutional Neural Networks, le quali generano e processano segnali nello spazio SO(3) e sono quindi naturalmente adatte a rappresentare e stimare orientazioni e LRF. Confrontiamo le prestazioni ottenute con quelle di metodi esistenti su benchmark standard, ottenendo risultati promettenti.

This thesis investigates the reference point effect on M&As. Prospect theory proposes that the reference dependence bias is firmly rooted in people’s minds, affirming that people rely heavily on a piece of relevant information while making decisions. This thesis applies this reference point to M&As, showing that M&A participants are subject to reference-dependence bias. The reference point theory explains the M&A motives in a new way. The results of this thesis offer important implications to M&A practitioners. Baker et al. (2012) suggest that the target’s reference price enhances the target’s bargaining power in the U.S. market, inspiring the author’s thinking that the reference point effect is likely to be reinforced in a competitive market and in the scenario where the bidder is in the face of considerable information barriers. In this pursuit, Chapter 3 studies the reference point effect on a sample of public acquisitions involving a U.K. target. Using the target 52-week high as the reference price, a positive relationship emerges between the reference price and the offer premium. Further, there is evidence of overpayment among domestic bidders whereas little evidence among cross-border bidders, indicating that the market acquiesces the payment according to the target reference point among cross-border bidders. Evidence that reference- dependence bias serves as the bargaining power is confirmed outside the United States. However, the real M&A motive of the bidder is unlikely to be revealed solely depending on the target reference point. Therefore, Chapter 4 extends Baker et al.’s paper (2012) by adding both the target and the bidder reference points. A Relative Reference Point (RRP) is proposed for M&A misvaluations as per Shleifer and Vishny (2003), indicating the extent to which the bidder is more overvalued relatively to the target. The joint reference point effects can explain the motivation of why bidders paying high offer premiums. The results obtained in this chapter show that bidders are likely to pay with stocks when RRP increases, suggesting that bidders accelerating the process of overvaluation dilution is a sign of bidder overvaluation. In addition, the offer premium increases with the RRP, indicating the motive of diluting overvaluation is to be seen by the target, leading targets to bargain over high offer premiums. When assessing the long-term performance of stock bidders, it became evident that bidders time the market by paying stocks according to the RRP. A direct implication of prospect theory is that people seek risk in the face of loss gauged by a reference point. Chapter 5 proposes the bidder reference point to assess the market anticipation effect. Investors suffer mental loss when their firm’s current performance is significantly below its best recently achieved performance. They anticipate that the firm will take risks to turn the table round. It was evident that the firm is rewarded with positive market reactions when it takes risks according to the market’s anticipation. In a further analysis, it also emerged that managers taking the market-anticipated risks exhibit greater efforts in the processes of M&A negotiation and post-merger integration, reflected in the low offer premiums paid to the target shareholders and positive long-term abnormal returns earned. This thesis has empirically investigated many implications of the reference point effect in the M&A context. The main aim of this thesis is to simplify M&A decisions for managers in order to structure M&A effectively.

Aquesta tesi analitza diversos aspectes de les motivacions individuals i de les seves implicacions en processos econòmics. Específicament, analitzo en detall criteris normatius que poden aplicar els individus com són els de justícia i reciprocitat. En la Introducció defineixo l'ús que en faig de conceptes com la reciprocitat, la justícia, la "dependència del menú" i els "punts de referència" donat que s'empren en el desenvolupament dels diferents capítols. També es descriu la metodologia emprada, que consisteix en alguns models teòrics sobre el comportament dels individus en situacions estratègiques, incorporant elements de la Teoria dels Jocs i l'ús de la metodologia experimental. En el segon capítol, " El concepte de justícia de Rabin i la provisió privada de béns públics", analitzo en detall les implicacions de la teoria de Rabin (1993) sobre el comportament estratègic d'individus. Aquest model introdueix en la funció d'utilitat , a més dels pagaments econòmics que un individu obté, aspectes psicològics com el sentit de justícia en les relacions econòmiques amb altres individus. En aquest capítol examino les implicacions d'una extensió de la teoria a un camp a on existeix una acumulació de resultats experimentals en contradicció amb el comportament predit pels models estàndard de la teoria dels jocs. Mostro que la teoria d'en Rabin és consistent amb el que s'anomena "splitting" però inconsistent amb el que es coneix com a "efecte MPCR". El tercer capítol, "Punts de referència i reciprocitat negativa en jocs seqüencials simples", analitza la influència que poden tenir certs vectors de pagaments no disponibles en un moment de decisió, anomenats "punts de referència", sobre la preferència per un altre conjunt de vectors de pagaments. Això es connecta amb l'atribució de certes intencions a altres subjectes quan trien determinats cursos d'acció en el joc. Mitjançant la utilització d'experiments s'obtenen resultats que confirmen la importància dels punts de referència en les consideracions de reciprocitat que empren els individus. El quart capítol, " Aspectes distribucionals i els punts de referència", analitza alguns aspectes que poden combinar-se amb els punts de referència en la atribució d'intencions. Aquests aspectes són: el pagament que podia rebre un agent en el punt de referència, el seu pagament relatiu a l'altre agent i, finalment, el pagament conjunt que podien obtenir els dos agents en el punt de referència. Els resultats experimentals obtinguts mostren que cap d'aquests efectes pot explicar per ell mateix els resultats. Finalment, el cinquè capítol, " Els joc del dilema dels presoners en forma seqüencial: Reciprocitat i efectes de dimensió del grup" estudia les reaccions dels individus a certes decisions d'altres individus del procés i els canvis d'aquestes reaccions amb la dimensió del grup. Els resultats experimentals obtinguts , mostren que el comportament observat és consistent amb consideracions de reciprocitat i d'aversió a la desigualtat.<br>This thesis analyzes several aspects of the motivations that drive individuals and their implications in economic processes. In particular, I analyze in detail normative criteria that individuals apply such as those of fairness and reciprocity. In the Introduction I define the use I make of the concepts of reciprocity, fairness, menu dependence and reference points that will be used in the course of the different chapters. The methodology developed in this thesis employs some theoretical models on the behavior of individuals in strategic interactions, using elements of Game Theory and Experimental Economics. In the second chapter, "On Rabin's Concept of Fairness and the Private Provision of Public Goods", I analyze in detail the implications of Rabin's (1993) theory of individual behavior and its implications. This model introduces, apart from the economic payoffs that the individual obtains in a strategic interaction, psychological phenomena, mainly a sense of fairness in the relation with other agents. In this chapter I analyze the implications of an extended version of this theory to a field where there exists a vast amount of experimental evidences contradicting the behavior predicted by standard game theoretical models. I show that Rabin's theory is consistent with one piece of evidence repeatedly found in experiments, the so call "splitting". I also show that the model is inconsistent with another piece of evidence in the field, the "MPCR effect". The third chapter, "Reference Points and Negative Reciprocity in Simple Sequential Games", analyzes the influence that certain payoff vectors, the "reference points", not attainable at that time, may have on the preference by other payoff vectors. This is connected with the attribution of certain intentions to the other players when selecting some courses of action. By using experiments I obtain results that confirm the importance of these reference points in the reciprocity considerations that individuals apply. Chapter four , "Distributional Concerns and Reference Points", analyzes some aspects that may interact with the reference points in the attributions of intentions. These aspects are the payoff to the agent from a given course of action, his/her relative payoff and the joint payoff. The experimental results show that none of these elements is able to explain by itself the results. Finally, the fifth chapter, "The Sequential Prisoner's Dilemma Game: Reciprocity and Group Size Effects" analyzes how aspects of the individual motivations interact with social aspects. In particular it studies how the reactions of individuals change with the dimension of the group in certain processes. The experimental results obtained show that in the prisoner's dilemma game (two-person and three-person games) the behavior of subjects may be consistent with reciprocity considerations and with inequality aversion considerations.
