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
Türkiye'de objektif ve öznel iyi oluş ilişkisini anlamak
No full textThesis (M.A) -- İstanbul Technical University, Institute of Social Sciences, 2017In this thesis, we investigate the association between two aspects of well-being in Turkey: objective and subjective. By employing the third European Quality of Life Survey for 2011, we assessed the generalized ordered logistic regression in which we conclude that if an improvement occurs in objective well-being components, subjective well-being is getting improved as well. Mental well-being is another indispensable well-being component which should be employed in well-being studies. Focusing on monetary measures of well-being is limited because of ignoring the subjectivity. Then we recommend the combined application of objective and subjective well-being as it provides promising and valuable insights.M.A
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
Yoksulları Hedefleme: Burkina Faso'da Sağlık Kartı Dağıtımı
No full textThesis (M.A) -- İstanbul Technical University, Institute of Social Sciences, 2019Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Sosyal Bilimler Enstitüsü, 2019This study compares two targeting mechanisms commonly used in Africa; proxy mean test (PMT) and community- based targeting (CBT). The performance comparison of the two methods is extended through a new set of poverty criteria: health and nutrition. First, consumption per capita household was used as the main welfare metric. Then, household health index was created based on the household survey. This index was used the determine household welfare level. Lastly, nutrition score was used as a welfare metric. For this purpose, household dietary diversity score (HDDS) was calculated based on 12 food group. Results showed that while PMT outperforms on consumption welfare metric, CBT outperforms on health and nutrition welfare metric. These indicated that poverty perception of the community doesn't solely base on the consumption like PMT formula.Bu çalışma, Afrika'da yaygın olarak kullanılan iki hedefleme mekanizmasını karşılaştırmaktadır; temsili ortalama testi (PMT) ve topluluk temelli hedefleme (CBT). İki yöntemin performans karşılaştırması yeni yoksulluk kriterleri seti ile genişletilmiştir. Bunlar sağlık ve beslenmedir. İlk olarak, kişi başına düşen hane halkı tüketimi ana refah ölçüsü olarak kullanılmıştır. Ardından, hanehalkı anketine dayanarak hane sağlığı endeksi oluşturulmuştur. Hanehalkı refah düzeyini belirlemek için bu endeks kullanılmıştır. Son olarak, beslenme puanı refah metriği olarak kullanılmıştır. Bu amaçla, hane halkı beslenme çeşitliliği skoru 12 besin grubu üzerinden hesaplanmıştır. Sonuçlar, PMT'nin tüketim refahı metriklerinde daha iyi performans göstermesine karşın, CBT'nin sağlık ve beslenme refahı metriklerinden daha iyi performans görüldüğünü göstermiştir. Bu sonuçlar, toplumun yoksulluk algısının PMT formülü gibi yalnızca tüketime dayanmadığını göstermiştir.Yüksek LisansM.
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
Three Essays on Poverty in Sub-Saharan Africa: Multidimensional Poverty Change in Zimbabwe; Long-Term Impact of Cash Transfers in Niger; and Targeting Efficiency of Social Protection Programs in Cameroon
No full textThis dissertation focuses on identifying the poor in Sub-Saharan Africa (SSA) and the potential of social assistance programs to address their condition. Each essay is related to one particular key step of the poverty alleviation agenda: poverty definition and measurement in Zimbabwe; targeting poor households in Cameroon; and impact evaluation of anti-poverty interventions in Niger.
The first essay explores changes in poverty across multiple dimensions in a period of dramatic economic crisis and recovery in Zimbabwe. The essay analyzes changes in household well-being between 2001, 2007 and 2011/12, using an Alkire-Foster multidimensional poverty index. Results indicate a large increase in multidimensional poverty across between 2001 and 2007, followed by a (smaller) decrease in poverty between 2007 and 2011/12 (recovery period after the hyperinflation peak in 2008). However, decomposition of the index shows significantly different trends in poverty dimensions over time, as for instance health related dimensions continued to deteriorate after 2007.
The second essay contributes to the policy debate on targeting by studying the ex-post efficiency of two targeting mechanisms employed in a cash transfer project in rural Cameroon: Proxy Means Testing (PMT) and community targeting. Results show a poor performance of community targeting in selecting households with low per capita consumption, compared to PMT targeting—whose errors remain high nonetheless. Communities tend to select small, isolated households with low physical and human capital, regardless of their actual consumption level, but produce variable outcomes. Overall results suggest that a higher coverage contributes to reducing targeting errors, and that better guidance should be provided to communities if the policy objective is to select low per capita consumption individuals.
The third essay investigate whether cash transfers induce investments in assets and productive activities that survive the termination of program payments using data from an unconditional cash transfer project in Niger 18 months after its termination. Based on quasi-experimental methods, results indicate that local saving/credit systems (tontines) participation and livestock ownership significantly increased among project participants. There is also evidence of improvement in private assets, micro-enterprises and agriculture. The findings imply that cash transfer programs can have long-term sustainable impacts in rural SSA.Ph. D
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
