Instituto de liderazgo público UNAL - ADEXUN : Una universidad para el liderazgo público
No full textilustraciones en blanco y negroLa creación del Instituto de Liderazgo Público de la Universidad
Nacional de Colombia (ilp unal - adexun) se encuentra arraigada en
la historia y los principios fundamentales de la Universidad Nacional
de Colombia (unal), así como en la misión de la Asociación de Exalumnos de la Universidad Nacional de Colombia (adexun). Ambas
instituciones comparten el compromiso de impulsar procesos democráticos y ciudadanos desde una perspectiva académica, centrándose en la gestión y transferencia de conocimiento para abordar las
problemáticas sociales colombianas.
Históricamente, la unal ha sido un referente en la formación de
ciudadanos integrales, agentes éticos de transformación cultural y
comprometidos con el país y el mundo. El liderazgo ha sido un elemento constitutivo de su adn institucional, cohesionando a la comunidad universitaria en su conjunto. La universidad ha buscado construir
una sociedad basada en el conocimiento, el diálogo constructivo y participativo y el intercambio transformador de saberes. Por otro lado,
la adexun, desde su fundación, ha tenido como misión integrar a los
egresados de la unal, promoviendo su liderazgo y posicionamiento a
nivel nacional e internacional. Además, ha estimulado el sentido de
pertenencia y solidaridad entre sus miembros, generando acciones
conjuntas para fortalecer la comunidad de exalumnos. (Texto tomado de la fuente)Primera edición, 2024Introducción

Managerial practices for designing circular economy business models: The case of an Italian SME in the office supply industry
No full textPurpose: The purpose of this paper is to investigate the managerial practices that companies can implement in order to design a circular economy business model and how companies can create and capture value from a circular economy business model. Design/methodology/approach: The paper adopts a single case study methodology with semi-structured interviews and company, supplier, and manufacturing site visits, conducted in a small-to-medium-size Italian company operating in the office supply industry. Findings: The theoretical setting maps a set of managerial practices for a circular economy business model and sets the research gaps and questions in a research framework designed along three main dimensions: value network, customer value proposition and interface, and managerial commitment. Then, through an empirical analysis, the findings reveal that the proposed dimensions are interdependent and reinforce each other. Moreover, the managerial commitment as moderating factor between the value network and the customer value proposition and interface dimensions is identified as essential for reaching the intended goals of circular economy business models. Research limitations/implications: This study maximizes the depth of the phenomenon under investigation by leveraging a single case study methodology, which ideally helps in a theory-testing approach as in the present case. Future research opportunities could be found in qualitative and quantitative studies to increase the generalizability of the findings of this paper. Practical implications: The paper presents a set of relevant managerial practices for circular economy business models that can be used by managers who have the will to embrace in practice circular economy principles to support the design, change, or upgrade of the business model of companies within which they operate. Originality/value: An interdisciplinary approach that integrates the research streams of circular economy, social psychology, organizational behavior, and business model design has been pursued to test the theoretical setting and the research framework for circular economy business models in a real-world context
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Hedging and Coordinated Risk Management: Evidence from Thrift Conversions
No full textThe authors propose an approach to analyzing risk management activities when multiple risks are bundled within a firm's assets or liabilities. They classify potentially bundled risks into two types: compensated risk and hedgeable risk. Firms earn rents for bearing compensated risk such as credit risk, and earn zero economic rents for bearing hedgeable risk such as interest rate risk. Because the costs associated with reducing hedgeable risk are lower than those associated with compensated risk, firms rationally eliminate hedgeable risks using either on- or off-balance sheet strategies. Thus, hedging becomes desirable even for risk-neutral or risk-seeking firms as a means of allocating risk. They denote this approach of optimal risk allocation among multiple risks with a firm as Coordinated Risk Management. The authors test the coordinated risk management approach by examining the interaction between interest rate risk (hedgeable risk) and credit risk (compensated risk) management at thrift institutions following conversion form a mutual-to-stock form of ownership. Although the concept of coordinated risk management applies to any firm, they use this sample because of data availability for the sample of converting thrifts and the control groups of non-converting institutions. The time-series findings are consistent with the coordinated management of interest rate risk and credit risk. In particular, immediately at conversion they observe decreased interest rate risk across institutions combined with a more gradual trend toward increasing credit risk. The negative relation between interest rate risk and credit risk is also significant in pooled tests. In addition, institutions use both on-balance sheet strategies and derivative instruments to reduce interest rate risk. This finding of decreasing interest rate risk occurs despite incentives to increase total risk following conversion. In light of the current discussions on the use of derivatives, this finding also indicates that thrifts use derivatives instruments for hedging rather than for speculative purposes. The cross-sectional results support models of optimal hedging. The authors provide evidence that interest rate risk hedging within an institution is positively associated with ex ante growth opportunities. They also provide evidence that managerial security holdings are a significant determinant of hedging activity. Finally, they report a negative association between managerial option holdings and interest rate risk hedging. Managers holding relatively high numbers of options maintain a risky position on-balance sheet with respect to unexpected changes in interest rates.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Computing the survival probability in the Madan–Unal credit risk model: application to the CDS market
No full textWe obtain a quasi-analytical approximation of the survival probability in the credit risk model proposed in [Madan, D.B. and Unal, H., Pricing the risk of default. Rev. Deriv. Res., 1998, 2(2), 121–160]. Such a formula, which extensive numerical simulations reveal to be accurate and computationally fast, can also be employed for pricing credit default swaps (CDSs). Specifically, we derive a quasi-analytical approximate expression for CDS par spreads, and we use it to estimate the parameters of the model. The results obtained show a rather satisfactory agreement between theoretical and real market data
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
