    The 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” 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

    We 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

    Three essays in labor, environmental, and behavioral economics

    This thesis is made up of three papers in the areas of labor, environmental, and behavioral economics. The first paper examines the impact that trade liberalization has had on wage inequality in Mexico since the North American Free Trade Agreement (NAFTA) was enacted in the mid 1990s. The second and third papers examine the problem of how to boost support for land uses widely perceived to benefit society, but present net costs to their prospective host communities. Such land uses have been termed not-in-my-backyard or NIMBY projects. I use wind farms as the type of NIMBY project to test the ideas in the latter two papers. In the first paper, I attempt to isolate one piece of NAFTA’s effect on wage inequality. I match annual industry wage and employment data with data on the tariffs the U.S. and Canada impose on goods from Mexico. A difficulty in isolating NAFTA’s effects through changes in U.S. and Canadian tariffs on Mexican exports is that these tariffs are highly correlated with the tariffs that Mexico’s other major trading partners impose on imports from Mexico. Since exports to these countries impact Mexican wages, leaving these relationships out of a model for estimation will leave the estimates for the effect that U.S. and Canadian tariffs have on wages biased. Since tariff data for this period is available for one of Mexico’s other top importers, I include this data to help mitigate the bias. The result is that the estimates for the effect that U.S. and Canadian tariffs have increase several fold. However, because the U.S. and Canada had little room left to lower their tariffs on the manufactured goods evaluated here, the small changes in tariffs that occurred in the post-NAFTA period result in calculations that attribute a less than one percent change in inequality to changes in U.S. and Canadian tariffs on Mexican exports. Additionally, it has been widely noted that while Mexico has a low-skill advantage compared to the U.S. and Canada, it may not be abundant in low-skilled labor in the global sense. Namely at the same time the U.S. and Canada lowered tariffs on Mexican exports, they also lowered tariffs on Chinese exports. With China arguably being the most abundant country in the world in low-skilled labor, Chinese exports to Mexico’s NAFTA partners could well be expected to cut into demand for Mexican products. I account for this effect by interacting the tariffs the U.S. and Canada charge on Mexican exports with the tariffs they respectively charge on Chinese exports. Since the tariffs the U.S. and Canada charge on Chinese exports are correlated with the tariffs they charge on goods from their other major exporters, I include tariffs from these partners as well to cut down on bias. The result is that this China effect is statistically significant. However, since the U.S. and Canada had already brought their tariffs on Chinese exports down to very low levels by 1995, the small changes each made in the post-NAFTA period appeared to have caused only miniscule changes in inequality in Mexico. The second paper analyzes how the more directly someone in a prospective host community sees compensation as addressing their concerns over a proposed land use, the less likely the person may be to see the offer of compensation as a bribe. Other studies note an often significant bribe effect, but cannot distinguish why one form of compensation might be seen as a bribe while another worth the same amount of money might not be. The NIMBY literature notes that compensation perceived as appropriate is more likely to be acceptable, but offers reasons that can primarily only be applied ex post in determining why a given offer of compensation might be seen as appropriate. The theory developed here can be applied ex ante in developing compensation and mitigation packages that are likely to be seen as appropriate and therefore acceptable. The theory developed here was tested in a survey on central Illinois residents regarding their responses to offers of different forms of compensation and mitigation for a hypothetical proposed wind farm. This population was chosen as it is made up of residents who primarily live in areas that are likely to face future wind farm development. The results here can be interpreted as how individuals might initially react to a proposed wind farm with accompanying offers of compensation and mitigation. The results are consistent with the idea that the more (less) directly individuals see compensation or mitigation as addressing their concerns, the less (more) likely they are to see it as a bribe. The results are robust to different estimation methods and a number of specifications. The NIMBY literature notes that offering compensation can cause support associated with civic duty to decline. No such decline is detected in the research here. However, since the wind farm proposed in the survey used here poses few or no perceived threats to public health, it differs dramatically from the nuclear waste sites associated with this crowding out of support associated with civic duty. That support associated with civic duty does not decline significantly is important since for all respondents and those with initially neutral or lower support, civic duty does appear to be a driving factor behind individuals’ support for the wind farm proposed. Further, while only a minority of respondents initially opposed the wind farm, most of them did not hold what are often referred to as NIMBY attitudes. Most of those who opposed the wind farm also opposed wind power in general. Indeed, respondents’ support or opposition towards wind power in general was one of the strongest predictors of how much respondents supported or opposed the wind farm proposed. The results here suggest that overcoming opposition to wind power in general may be especially helpful in overcoming opposition to wind farms in individuals’ back yards. The third paper primarily examines the effect of others’ support on individuals’ support for a wind farm hypothetically proposed one mile from their home. It also investigates how others’ support may affect individuals’ support for wind power in general and how directly individuals see compensation as addressing their concerns. Others’ support is only found to significantly affect support for the wind farm among those who have neutral or lower support for wind power in general. It is especially noteworthy that others’ support significantly affects these groups since the finding is consistent with conformity as a driving force, but not reciprocity—two of the primary behaviors believed to motivate conditional cooperation. Others’ support will only move a reciprocator to engage in a kind act—one that s/he believes will confer some benefit to others or society. It is unlikely that those who have neutral or lower support for wind power believe hosting a wind farm constitutes a kind act. Alternatively, it could be that respondents in these groups saw high others’ support as signaling fewer impacts from the wind farm than they previously expected. For respondents in these groups, there was no significant difference in the impacts expected among those in the high treatment group versus those in the low group. However, the results for those with neutral or lower support for wind power may be sensitive to the small number of respondents who indicated these levels of support. It also appears that others’ support for the wind farm proposed positively affects individuals’ support for wind power in general. Whether this effect is long-lasting or fleeting cannot be determined from the data gathered. It also appears that others’ support positively affected how directly the following groups saw compensation as addressing their concerns: those with initially neutral or lower support for the proposed wind farm and those with neutral or lower support for wind power in general. While the effect of how directly respondents saw compensation as addressing their concerns is positively significant for all respondents, those with initially neutral or lower support for the wind farm proposed, and those with high support for wind power in general, it is not for those with neutral or lower support for wind power in general. Overall, the work here finds that others’ support does appear to have significantly affected individuals’ behavior in a real world setting—providing further evidence to the literature that conditional cooperation may matter in how individuals make significant economic decisions in their everyday lives.Item withdrawn by Mark Zulauf ([email protected]) on 2013-07-08T13:32:06Z Item was in collections: University of Illinois Theses & Dissertations (ID: 1) No. of bitstreams: 1 Hanig_Ross.pdf: 3886164 bytes, checksum: fceddc779b78b4134e68fca712e4f3db (MD5)Made available in DSpace on 2013-08-22T16:48:06Z (GMT).

    The Returns to Wages for Mexican Workers in a Post NAFTA World: Has the Gap in Returns to Wages Grown Between Mexican Workers in the U.S. and their Domestic Counterparts?

    No full text
    I test to see if the returns to wages for Mexican workers have changed in the Pre- and Post-NAFTA periods using data from the Mexican Migration Project using a pseudo panel analysis framework. The results here suggest that the returns to wages for workers in Mexico have declined significantly in the Post-NAFTA period. However, due to severe measurement error in the data on wages earned in Mexico, and consequently insufficient data to provide suitable cohort sizes, the results here should be viewed as suggestive rather than inferential. I present several tables at the end of the paper with similar regression results from the INEGI data set which do not suffer these problems in measurement error and will form the basis for a significantly updated draft of this paper to be presented at the AAEA conference. The INEGI results suggest the workers in Mexico may actually have not been made significantly worse off from NAFTA. However, the coefficient for workers in the agricultural sector declines, suggesting this sector may have incurred significant losses in wage-returns. These latter results appear consistent with the other work finding that at best, NAFTA may have had an insignificant impact on Mexican wages. The updated version of this paper will present cross-sectional as well as pseudo-panel findings with cohorts grouped by five-year birth spans, gender, and educational attainment to better account for the generational effects and endogeneity with fixed effects.Labor and Human Capital,

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
