Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
The drug addict : intergenerational family therapy and the Lulama programme
Get PDFMA (Clinical Psychology), North-West University, Potchefstroom CampusThe question posed in this research is whether intergenerational family
therapy included in the Lulama Programme has a different effect on the addict
and his family of origin than the Lulama Programme alone. This topic was
chosen as the problem of drug abuse and its treatment poses an ever-increasing
dilemma for the South Afriecan Health Care professions .
In the literature study numerous researchers indicate that the family and the
structure within it lead · to and aggravate drug addiction . The young child
involved in the triangle, or the need to maintain the equilibrium within the
family for survival , are just a few examples mentioned . Further, a look is taken
at what some theorists see as intergenerational family therapy and how it is
applied. The theorists that were discussed were Bowen, Boszormenyi-Nagy
and Spark and Napier.
Against this background a programme including intergenerational family
therapy was designed and applied to a section of the population at Lulama.
This was consequently compared to a section of the populaton which only went
through the Lulama Programme.
The results indicated that the null hypothesis had to be accepted for the researcher.
The results indicated that there were significantly more differences
between the two groups during post-testing on the measuring instruments
used . Some of the differences were in favour of the Lulama Programme and
others were in favour of the combined programme. There was also a significant
difference in some dimensions in the level of growth that the two pro-
grammes had precipitated . Here too, there was a discrepancy in the success
of the two programmes.
The results also indicated that there were several problems. One of the main
problems was that the sample was too small. The reason for this was the
ethical and practical problems involved in obtaining the sample. Other
questions suet, as the tests used and the length of the programme and the
period between the pre- and post-testing also became an issue.
It is the view of this researcher that research in this field is vitally important.
It has become clear in this research that the programme including the
intergenerational family therapy had limited success, more research has to be
done before this becomes a programme that can be widely recommended.Master
The evaluation of a premarital enrichment programme for second marriages
Get PDFThesis (M.A. (Clinical Psychology))--North-West University, Potchefstroom Campus, 2005.The aim of the research was to evaluate the premarital enrichment programme designed by Pretorius (1997) for couples who wish to remarry. The study was motivated by literature, which shows a high likelihood of divorce among divorcees who remarry. Three interested couples responded to advertisements placed in a local Potchefstroom newspaper and announcements made in churches. A qualitative (case study method) research design was used. The programme consisted of six two-hour sessions. The programme was conducted over two weekends. The first
three sessions were held with all three couples and the last three sessions with each couple separately due to conflicting schedules. The effect of the programme was assessed by five measuring instruments, participants' metaphoric drawings of their relationships, semi-structured interviews, and the researcher's observations of the interaction between the participants. The
assessment took place a week before and four weeks after the programme presentation. The results obtained indicated that two of the couples experienced changes whilst the other couple experienced minimal change. The change that occurred in the two couples were with regards to their communication and conflict management, their implementation of boundaries, intimacy, security in their relationship, growth, and dyadic adjustment. It was concluded that the premarital enrichment programme prepared two couples for remarriage, specifically with regards to their
adjustment in the relationship.Master
Short message service (sms) and loneliness in a group of adolescents
No full textThesis (M.A. (Clinical Psychology))--North-West University, Potchefstroom Campus, 2007The aim of the research was to explore the relationship between the use of SMS communication by adolescents and their perceived feelings of loneliness. The SMS seems to be the new communication medium for young people as they are most comfortable with and enthusiastic about this technology and its applications. The adolescent stage is characterised by the building of own social networks, the definition of boundaries between themselves and parents, self-presentation constructed on a social stage in relation to others and characterised by the development of romantic attachments, feelings of anxiety, self-esteem development and maintenance which may result in feelings of isolation and loneliness. Loneliness can be defined as an emotional and cognitive reaction to having fewer and less satisfying relationships than one desires. This includes the absence or self-perceived absence of satisfying social relationships and the unpleasant experience that occurs when a person's network of social relations is deficient in some important way. The motivation for this research was to get insight into the relationship between the use of SMS communication and loneliness in the South African context. An internet search on the 13th February 2006 indicated that no research has yet been done on the relationship between the use of the SMS and loneliness of adolescents in South Africa.
An availability sample was used. One hundred and seventeen Grade 11 and 12 learners from two schools in the North West Province participated in the research project. An explanatory cross-sectional survey design with features of qualitative data analysis was used in this investigation. Three methods were used to obtain data, namely the UCLA Loneliness Scale (Version 3), Satisfaction with Life Scale as well as a self-compiled questionnaire. After scoring the UCLA scale the researcher determined which of the participants had the highest level of loneliness and the lowest level of loneliness. Two groups were chosen, each consisting or 15 learners, according to the highest and lowest scores on the loneliness scale respectively. These two groups represented the top and bottom 14% of the sample. The data obtained from the self-compiled questionnaire and Satisfaction with Life scale were qualitatively compared. Analysis of the data indicated that there might be a relationship between the experience of loneliness and the following: gender; number of siblings; involvement in romantic relationships; amount of money spent on bill (financial constraints); quantity of SMS messages sent and received; need to stay in contact with friends over the weekend; reasons for sending SMS messages; feelings regarding sending or receiving SMS messages; feelings regarding no response to SMS messages; feeling with regard to not receiving SMS messages from a friend for a long time; initiating of friendships via cellphone and the SMS rather than face-to-face communication. Suggestions for future research projects were made.Master
