Estudio exploratorio de variables a través de análisis estructural MICMAC en la prestación del servicio en la administración pública municipal de Monterrey México
Full text linkDurante muchos años se ha intentado subsanar las graves deficiencias de la Administración Pública municipal en los países con una economía en transición, como es el caso de México. Situación que a pesar de que la administración pública municipal cuenta con avances en capacitación, modernización y parámetros de medición del servicio, aún tiene graves rezagos sistémicos y problemáticas como: conflicto de intereses, procedimientos lentos, prepotencia e infraestructura deficiente, entre las quejas más recurrentes de los ciudadanos de la ciudad de Monterrey respecto de la prestación del servicio por parte de la administración pública municipal; debido a ello, se realizó un estudio exploratorio de variables a través del sistema MICMAC (análisis estructural), es mediante este estudio que se plantea encontrar las variables más impactantes en las que la administración debería realizar acciones correctivas en la prestación del servicio del municipio de Monterrey, México
Implications Of Changes In Tax Rates For Firm Debt Levels: Evidence From The 1986 Tax Reform Act
Full text linkIn a recent paper, Jalbert (2002) develops and tests valuations equations for firms that are subject to pass-through taxation and for firms that are subject to double taxation. This work is extended by Jalbert and Dukes (2003) who examine the implications of a zero percent tax rate on dividend income. In this paper, we extend this line of work by developing equations for the implied changes in firm capital structure around a change in tax regime. The results show that firms change their capital structures in predictable ways when tax rates change. These results are important for determining likely changes in firm policy around future tax regime changes. 
Dollar Index Adjusted Stock Indices
Full text linkThis paper presents stock indices that reflect changes in both stock value and underlying currency value. An earlier study develops the first known currency adjusted stock index. This paper extends the literature by utilizing a better measure of US dollar value to develop currency value adjusted indices. We examine distributional properties of the indices and determine the portion of wealth change attributable to stock value change and currency value change. The results show significant differences in return variance between original and dollar adjusted indexes. The results further show that changes in the stock index level explain most wealth changes. However, changes in currency value explain as much as 14.9 percent of wealth changes
Intraday Index Volatility: Evidence From Currency Adjusted Stock Indices
Full text linkA recent research stream develops currency adjusted stock indices. The analysis in previous papers is limited to daily closing data. This paper extends the existing body of literature by examining tick data. We examine tick data from 2002 through 2013 for eight indices. In general, results show the Dollar Index adjusted indices display significantly lower variation than the unadjusted indices. Correlation between the Dollar Index and unadjusted stock indices is negative. Both raw and Dollar index adjusted indices display departures from intra-tick symmetry. The results also show that Dollar Index changes explain as much as fifteen percent of wealth changes
International Evidence On Currency Adjusted Stock Indexes
Full text linkRecent literature examines currency value adjusted indexes. The extant research examines U.S. stock indexes as adjusted for the value of the U.S. dollar and the value of gold. The literature examines only U.S. stock indexes. This paper extends the existing literature by examining currency adjusted stock indexes from eight countries. The analysis includes daily closing data from 1993-2016. The results show that currency adjusted indexes produce significantly different return distributions than original indexes. Further, currency value changes explain as much as 31 percent of total wealth changes, a result substantially higher than previously reported for U.S. currency adjusted indexes. The combined evidence indicates that currency value changes impact total wealth changes more for international indexes than for U.S. indexes.
 
Causality And Cointegration Of Currency-Adjusted Stock Indices: Evidence From Close-Of-Day Data
Full text linkA recent line of research develops currency adjusted stock indices. These indices incorporate the effects of both stock value changes and underlying currency value changes to measure wealth changes. This paper extends the extant literature by examining time series properties of currency-adjusted indices. This research examines daily data for eight existing stock indexes and their currency adjusted counterparts for the period 1993-2013. The paper includes cointegration and Granger causality analyses. Results show cointegration between each combination of series examined. About half the pairwise index combinations display bidirectional Granger causality
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
