The Terminal Value (TV) Performing in Firm Valuation: The Gap of Literature and Research Agenda

The uncertainty about the future of firms must be modeled and incorporated in the valuation of enterprises outside the explicit period of analysis, i.e., in the continuing or terminal value (TV). There is a multiplicity of factors that influence the TV of firms which are not being considered within current evaluation models. This aspect leads to the incurring of unrecoverable errors, thus leading to values of goodwill or bad will far away from the substantial value of intrinsic assets. As a consequence, the evaluation results will be presented markedly different from market values. There is no consensus in the scientific community about the method of computation of the TV as a forecast in an infinite horizon. The size of the terminal, or non-explicit period, assumed as infinite, is never called into question by scientific literature, or the probability of business bankruptcy. This paper aims to promote a study of the existing literature on the TV, to highlight the fragility of the evaluation models of companies that have been used by the academic community and by financial analysts, and to point out lines for future research to minimize these errors.

A next application prediction service using the BaranC framework

Predicting user behaviour enables user assistant services provide personalized services to the users. This requires a comprehensive user model that can be created by monitoring user interactions and activities. BaranC is a framework that performs user interface (UI) monitoring (and collects all associated context data), builds a user model, and supports services that make use of the user model. A prediction service, Next-App, is built to demonstrate the use of the framework and to evaluate the usefulness of such a prediction service. Next-App analyses a user's data, learns patterns, makes a model for a user, and finally predicts, based on the user model and current context, what application(s) the user is likely to want to use. The prediction is pro-active and dynamic, reflecting the current context, and is also dynamic in that it responds to changes in the user model, as might occur over time as a user's habits change. Initial evaluation of Next-App indicates a high-level of satisfaction with the service.

A probabilistic approach to user mobility prediction for wireless services.

Mobile and wireless networks have long exploited mobility predictions, focused on predicting the future location of given users, to perform more efficient network resource management. In this paper, we present a new approach in which we provide predictions as a probability distribution of the likelihood of moving to a set of future locations. This approach provides wireless services a greater amount of knowledge and enables them to perform more effectively. We present a framework for the evaluation of this new type of predictor, and develop 2 new predictors, HEM and G-Stat. We evaluate our predictors accuracy in predicting future cells for mobile users, using two large geolocation data sets, from MDC [11], [12] and Crawdad [13]. We show that our predictors can successfully predict with as low as an average 2.2% inaccuracy in certain scenarios.

Homesick for the unheimlich: back to the uncanny future in Alien: Isolation

In 2014 Sega released Creative Assembly’s Alien: Isolation, a video game sequel to the 1979 film Alien. As an attempt to create both an authentic homage to the Alien franchise and a credible successor to Ridley Scott’s original film, Alien: Isolation was received as both a work of remediated nostalgia and as a deeply uncanny survival horror. This article discusses Alien: Isolation framed by theories of the uncanny (the unhomely) and of nostalgia (the homely), with the aim of revealing how the production design of the game reconciled these seemingly contradictory but nonetheless overlapping aesthetic qualities. By drawing on examples from Alien: Isolation’s visual and level design, this article discusses how the integration of nostalgic and uncanny qualities could be of value to horror and sci-fi game design, in particular to the development of sequels within existing franchises, and to remediations, remakes and reboots.

Asociación entre la escala de riesgo Framingham y el puntaje de calcio coronario

Introducción: Entre las diferentes herramientas clínicas para evaluar la presencia de enfermedad coronaria mediante puntajes, la más usada es la Escala de Riesgo cardiovascular de Framingham. Desde hace unos años, se creó el puntaje de calcio coronario el cual mide el riesgo cardiovascular según la presencia de placas ateromatosas vistas por tomografía computarizada. Se evaluó la asociación entre la escala de Framigham y el puntaje de calcio coronario en una población de sujetos sanos asintomáticos. Metodología: Se realizó un estudio transversal para evaluar la asociación entre el puntaje de calcio coronario y la escala de Framingham en sujetos asintomáticos que se practicaron exámen médico preventivo en la Fundación Cardioinfantil- Instituto de Cardiología (FCI-IC) en el periodo comprendido entre 1 de Julio 2011 hasta el 31 de octubre de 2015. Resultados: Se evaluaron 262 pacientes en total. La prevalencia de riesgo cardiovascular fue bajo en un 77.86% de la población, medio en 18.70% y alto en 3.44%, según la escala de Framingham. El riesgo cardiovascular según el puntaje de Calcio coronario fue nulo 70.99%, bajo en 21.75%, medio en 4.19%, severo en 3.05%. Se encontró una asociación entre ambos puntajes para riesgo estadísticamente significativa (p0,00001) Discusión: El riesgo cardiovascular establecido por escala de Framingham se relaciona de forma significativa con la presencia de placas aterioscleróticas. El estudio demostró que en una muestra de sujetos asintomáticos, hay una alteración estructural coronaria temprana.

Congruencia entre los valores personales y organizacionales y su influencia con el engagement en el trabajo : estudio de caso en una organización del sector salud

La capacidad de gestión del personal se ha convertido en un imperativo para las organizaciones modernas. Por tanto se vienen introduciendo temas como la administración en valores y el engagement de los trabajadores. Sin embargo, la relación entre estos dos aún no ha sido estudiada. El presente estudio tiene como objetivo analizar el efecto que tiene el grado de articulación y reconocimiento de los valores organizacionales y personales y organizacionales sobre los niveles de engagement de los empleados. Para esta investigación se utilizó una muestra constituida por 54 trabajadores de una organización del sector salud de la ciudad de Bogotá a quienes les fueron aplicadas dos escalas: el Inventario para Medir la Articulación entre la Persona y la Organización (Inventario APO) y Utrech Work Engagement Scale (UWES). Como principal resultado se obtuvo que de las tres dimensiones consideradas predictoras del engagement, solamente el reconocimiento de los valores organizacionales tuvo un efecto estadísticamente significativo.

Repensar=Reutilizar. o abandono como oportunidade. Fábrica Robinson: o instante na construção de um tempo provisório

Esta investigação procura mostrar/problematizar programas que questionem a reutilização de lugares, através de uma proposta de projeto provisório de arquitetura, no panorama do Património Industrial, num processo de revitalização. O intuito é procurar modelos/ações que possam responder às transformações, partindo do problema do abandono, dos espaços pós-industriais. O objetivo principal consiste em criar um processo de aproximação à problemática da reutilização cujo processo de elaboração de projeto encontra nas suas formas de produção e operação um discurso que faz a síntese entre prática artística, posição curatorial e arquitetura, na elaboração de um programa para um lugar revitalizando-o. O objeto deste estudo faz parte de uma investigação de pesquisa por projeto e encontra lugar no conjunto arquitetónico da Fábrica Robinson, em Portalegre, cuja apropriação inicial de parte do Convento de S. Francisco dá hoje lugar ao Espaço Robinson. O reconhecimento deste conjunto, como lugar de encontro entre um passado recente e um futuro pendente, marcou a proposta projetual. Proposta de projeto temporário cujo conceito estabelece a viabilidade de apropriação como forma de atuação provisória, subjacente ao ato de reutilizar, criando novos programas de ocupação, promovendo novas ideias e definições de património e assim devolvendo o significado às estruturas industriais vazias. O que preservar e como conservar pode demarcar a importância de salvaguarda deste património e a previsão da sua transmissão para o futuro, fixada pela ideia de preservação. A Fábrica Robinson e a revitalização urbana deste espaço configura, hoje, uma nova oportunidade para estes conjuntos arquitetónicos, e a importância da sua salvaguarda, na valorização do Património Industrial. O trabalho pretende demonstrar a ordem de relação entre programa e lugar no debate interdisciplinar e a hipótese de concretização projetual que preencha um vazio temporalmente suspenso; ABSTRACT: Rethinking = Reuse: The abandonment as opportunity Robinson Factory: The instant in the construction of a provisory time This research aims to show architectural programs that question the reuse of places in the context of industrial heritage, through an architectural design, in a revitalization process. The aim is to look to models / actions that, starting with the abandonment problem, may answer to the post-industrial spaces transformations. The main goal is to create an approximation process to the problem of reuse, whose project design process finds in its production and operations forms a symbiosis between artistic practice, curatioral approach and architecture, in the development of a program to revitalize a place. The object of this study is part of a research project / research by design concerning the architectural complex Fábrica Robinson located in Portalegre, whose original appropriation of part of Convento de S. Francisco is today occupied by Espaço Robinson. The acknowledgment of this complex as a space placed in-between a recent past and a pending future marked the design proposed. A temporary design proposal whose concept establishes the validity of the temporary action, underlying to the act of reuse, creating new occupation programs, promoting new ideas and heritage definitions and thus given back meaning to the empry industrial structures. What to preserve and how to save may mark the importance of safeguarding this heritage and the prediction of its transmission to the future, set by the idea of preservation. The Fábrica Robinson and the urban regeneration of this area sets itself as a new opportunity to safeguard these architectural ensembles and enhance the value of the industrial heritage. This study intend to show the relationship between the program and a vacant place, through a temporary proposal, supported by the interdisciplinary debate and the hypothesis of design implementation that completes a void temporarily suspended.

Customer Loyalty toward grocery retailing service: a multidimensional approach to costumer perceived value

Structured abstract Purpose: To deepen, in grocery retail context, the roles of consumer perceived value and consumer satisfaction, as antecedents’ dimensions of customer loyalty intentions. Design/Methodology/approach: Also employing a short version (12-items) of the original 19-item PERVAL scale of Sweeney & Soutar (2001), a structural equation modeling approach was applied to investigate statistical properties of the indirect influence on loyalty of a reflective second order customer perceived value model. The performance of three alternative estimation methods was compared through bootstrapping techniques. Findings: Results provided i) support for the use of the short form of the PERVAL scale in measuring consumer perceived value; ii) the influence of the four highly correlated independent latent predictors on satisfaction was well summarized by a higher-order reflective specification of consumer perceived value; iii) emotional and functional dimensions were determinants for the relationship with the retailer; iv) parameter’s bias with the three methods of estimation was only significant for bootstrap small sample sizes. Research limitations:/implications: Future research is needed to explore the use of the short form of the PERVAL scale in more homogeneous groups of consumers. Originality/value: Firstly, to indirectly explain customer loyalty mediated by customer satisfaction it was adopted a recent short form of PERVAL scale and a second order reflective conceptualization of value. Secondly, three alternative estimation methods were used and compared through bootstrapping and simulation procedures.

Expansion of sunflower crop production in Brazil: a survey of future trends.

Sunflower cropped area in Brazil has been showing potential possibilities to be increased in a short period of time for biofuel production. Planning the activities is one of the requirements for the success of future cropped area expansion. This requires a previous survey that identifies future trends in the transformation and rearrangement of the sunflower agro-industry sector and also identifies technological needs that may affect this process. With the objectives of identify future trends and technological needs, a value production chain was built and a questionary was applied to agents of all the sectors participating at the V National Brazilian Symposium of Sunflower and at the XVII Sunflower National Research Meeting Network. The results pointed out a strong tendency for area expansion in the next two to five years (75%); being as a secondary follow-up crop (83%) specially after soybean and top be used for biofuel (77%). The main research needs were linked with disease control, crop zoning and varietal improvement for disease resistance and high oleic oil content. Also considering the vision of and concerns regarding the future expansion and transformation of the sunflower productive complex, it is believed that the expansion is a consolidated trend, requiring a strategic sector planning associated with an economic and technological police for its success within the Brazilian agribusiness.

The Experience of Adult Literacy as a Learning Process in the Formation of Future Educators

Learning is constructed when it is significant, therefore, promoting experiences that can make sense and joy, which constitutes a challenge in the formation of future educators. In this article, we share the considerations emanated from an investigation that gathers the experience of alphabetizing adults, carried out by college students as part of their formation. As a result, this creates a learning process that favors the respect to diversity and the value of reading and writing as the liberation of mankind. The work displays the learnings constructed, the ways of respecting diversity that emerge from the alphabetizing experience, and the value that the students give to reading and writing as a liberating way of expression.

Prediction of a low-risk concentration of diflubenzuron to aquatic organisms and evaluation of clay and gravel in reducing the toxicity.

Resumo: Predição da concentração de baixo risco de diflubenzuron para organismos aquáticos e avaliação da argila e brita na redução da toxicidade. O diflubenzuron é um inseticida que além de ser usado agricultura, tem sido amplamente empregado na piscicultura, apesar do seu uso ser proibido nesta atividade. Este composto não consta na lista da legislação brasileira que estabelece limites máximos permissíveis em corpos de água para a proteção das comunidades aquáticas. No presente trabalho, a partir da toxicidade do diflubenzuron em organismos não-alvo, foi calculada a concentração de risco para somente 5% das espécies (HC5). O valor deste parâmetro foi estimado em aproximadamente 7 x 10-6 mg L-1 . Este baixo valor é devido à extremamente alta toxicidade do diflubenzuron para dafnídeos e à grande variação de sensibilidade entre as espécies testadas. Dois matérias de relativamente baixo custo se mostraram eficientes na remoção da toxicidade do diflubenzuron de soluções contendo este composto. Dentre esses materiais, a argila expandida promoveu a redução em aproximadamente 50% da toxicidade de uma solução contendo diflubenzuron. Os resultados podem contribuir para políticas públicas no Brasil relacionadas ao estabelecimento de limites máximos permissíveis de xenobióticos no compartimento aquático. Também, para a pesquisa de matérias inertes e de baixo custo com potencial de remoção de xenobióticos presentes em efluentes da aquicultura ou da agricultura. Abstract: Diflubenzuron is an insecticide that, besides being used in the agriculture, has been widely used in fish farming. However, its use is prohibited in this activity. Diflubenzuron is not in the list of Brazilian legislation establishing maximum permissible limits in water bodies for the protection of aquatic communities. In this paper, according toxicity data of diflubenzuron in non-target organisms, it was calculated an hazardous concentration for only 5% of the species (HC5) of the aquatic community. This parameter value was estimated to be about 7 x 10 -6 mg L -1 . The low value is due to the extreme high toxicity of diflubenzuron to daphnids and to the large variation in sensitivity among the species tested. Two relatively low cost and inert materials were efficient in removing the diflubenzuron from solutions containing this compound. Among these materials, expanded clay shown to promote reduction of approximately 50% of the toxicity of a solution containing diflubenzuron. The results may contribute to the establishment of public policies in Brazil associated to the definition of maximum permissible limits of xenobiotics in the aquatic compartment. This study is also relevant to the search of low cost and inert materials for xenobiotics removal from aquaculture or agricultural effluents.

Prediction Nomogram for 68Ga-PSMA-11 PET/CT in different clinical settings of PSA failure after radical treatment for Prostate Cancer

Objective The objective of this study was to develop a clinical nomogram to predict gallium-68 prostate-specific membrane antigen positron emission tomography/computed tomography (68Ga-PSMA-11-PET/CT) positivity in different clinical settings of PSA failure. Materials and methods Seven hundred three (n = 703) prostate cancer (PCa) patients with confirmed PSA failure after radical therapy were enrolled. Patients were stratified according to different clinical settings (first-time biochemical recurrence [BCR]: group 1; BCR after salvage therapy: group 2; biochemical persistence after radical prostatectomy [BCP]: group 3; advanced stage PCa before second-line systemic therapies: group 4). First, we assessed 68Ga-PSMA-11-PET/CT positivity rate. Second, multivariable logistic regression analyses were used to determine predictors of positive scan. Third, regression-based coefficients were used to develop a nomogram predicting positive 68Ga-PSMA-11-PET/CT result and 200 bootstrap resamples were used for internal validation. Fourth, receiver operating characteristic (ROC) analysis was used to identify the most informative nomogram’s derived cut-off. Decision curve analysis (DCA) was implemented to quantify nomogram’s clinical benefit. Results 68Ga-PSMA-11-PET/CT overall positivity rate was 51.2%, while it was 40.3% in group 1, 54% in group 2, 60.5% in group 3, and 86.9% in group 4 (p < 0.001). At multivariable analyses, ISUP grade, PSA, PSA doubling time, and clinical setting were independent predictors of a positive scan (all p ≤ 0.04). A nomogram based on covariates included in the multivariate model demonstrated a bootstrap-corrected accuracy of 82%. The nomogram-derived best cut-off value was 40%. In DCA, the nomogram revealed clinical net benefit of > 10%. Conclusions This novel nomogram proved its good accuracy in predicting a positive scan, with values ≥ 40% providing the most informative cut-off in counselling patients to 68Ga-PSMA-11-PET/CT. This tool might be important as a guide to clinicians in the best use of PSMA-based PET imaging.

Performance assessment of vehicular connectivity in hybrid electric vehicles for fuel and emissions reduction

Nowadays, the spreading of the air pollution crisis enhanced by greenhouse gases emission is leading to the worsening of global warming. Recently, several metropolitan cities introduced Zero-Emissions Zones where the use of the Internal Combustion Engine is forbidden to reduce localized pollutants emissions. This is particularly problematic for Plug-in Hybrid Electric Vehicles, which usually work in depleting mode. In order to address these issues, the present thesis presents a viable solution by exploiting vehicular connectivity to retrieve navigation data of the urban event along a selected route. The battery energy needed, in the form of a minimum State of Charge (SoC), is calculated by a Speed Profile Prediction algorithm and a Backward Vehicle Model. That value is then fed to both a Rule-Based Strategy, developed specifically for this application, and an Adaptive Equivalent Consumption Minimization Strategy (A-ECMS). The effectiveness of this approach has been tested with a Connected Hardware-in-the-Loop (C-HiL) on a driving cycle measured on-road, stimulating the predictions with multiple re-routings. However, even if hybrid electric vehicles have been recognized as a valid solution in response to increasingly tight regulations, the reduced engine load and the repeated engine starts and stops may reduce substantially the temperature of the exhaust after-treatment system (EATS), leading to relevant issues related to pollutant emission control. In this context, electrically heated catalysts (EHCs) represent a promising solution to ensure high pollutant conversion efficiency without affecting engine efficiency and performance. This work aims at studying the advantages provided by the introduction of a predictive EHC control function for a light-duty Diesel plug-in hybrid electric vehicle (PHEV) equipped with a Euro 7-oriented EATS. Based on the knowledge of future driving scenarios provided by vehicular connectivity, engine first start can be predicted and therefore an EATS pre-heating phase can be planned.
