The effects of iron deficiency on infants' developmental test performance
No full textAim: To assess the effects of iron deficiency on developmental test scores in infants. Methods: This prospective, single-blind, controlled clinical intervention study was made on 108 children aged 6-30 mo who applied to our paediatric outpatient clinic. The cases were classified as control (n = 31, haemoglobin greater than or equal to11 g/dl, serum ferritin > 12 mug/l, MCV greater than or equal to70 fl), non-anaemic iron deficiency (NAID, n = 40, haemoglobin greater than or equal to 11 g/dl, serum ferritin less than or equal to 12 mug/l, MCV greater than or equal to70 fl) and iron deficiency anaemia (IDA, n = 37, haemoglobin <11 g/dl, ferritin &LE; 12 &mu;g/l, MCV <70 fl) due to their anaemia status. In each group, MCV, haemoglobin and ferritin levels were measured, and Denver Developmental Screening Test (DDST) and Bayley Scales of Infant Development (BSID-I) were administered before and after a 3-mo follow-up. IDA and about half of the NAID subjects were treated with oral iron for 3 mo. Results: Subjects with iron deficiency showed significantly lower developmental test scores both with BSID-I and DDST-II compared to their iron-sufficient peers (p < 0.05). After 3 mo of iron treatment, lower mental developmental test scores were no longer observed among the IDA and NAID groups whose anaemia and iron deficiency were also corrected. No significant differences were found between control NAID and control IDA groups on DGTT-II results after treatment. The difference in motor and mental developmental scores did not appear to depend on environmental and family factors considered in the analyses. Conclusion: These findings support the conclusions that iron deficiency may cause lower mental I and motor test scores in infants and these adverse effects can be improved by iron therapy
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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
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
Context Representation for the Semantic Web
No full textThe unambiguous and effective delivery of data and knowledge on the Web relies heavily on the correct representation and understanding of the associated contexts. However, the current way of encoding data and knowledge on the Web is largely ad hoc. Contexts are often embedded in the application program or are implied by the application- or community-specific agreements. This makes the linking and reusing of data and knowledge, and thus the integration of Web applications, a difficult problem. Therefore, building the architectural support for contexts is one of the major challenges for the Web, and in particular, for the Semantic Web. In this paper, we propose a framework for contexts that provides formal and explicit representations for the usually implicit contextual assumptions of data and knowledge on the Web. This is done by supporting the description of logic institutions, relations of contexts, and provenance. Our framework is able to tackle some critical issues for extending Web as a "Social Machine", such as, permitting different views on the same data, faithful knowledge integration and situation awareness
Early adverse emotional response to childbirth in Turkey: The impact of maternal attachment styles and family support
No full textEarly adverse emotional response which is often detected in the form of depressive symptoms is a predictor of postpartum depression following the birth. The aim of our study is to highlight contextual and individual factors that have an impact on mothers' depressive symptoms during the early postpartum period. One hundred mothers participated in the study. Maternal depressive symptoms were screened by Edinburgh Postpartum Depression Scale (EPDS), and maternal anxiety level was assessed by State-Trait Anxiety Inventory (STAI) at early postpartum period (7-10 days). The Multidimensional Scale of Perceived Social Support (MSPSS) was used for the assessment of maternal social support. The Adult Attachment Scale (AAS) was used to determine the attachment style of the mother. The mean EPDS score of mothers who live in extended families is found to be significantly lower than mothers who live in nuclear families (extended families 7.13 +/- 7.39, nuclear families 11.77 +/- 5.96, p=0.006). Significant positive correlations were found between EPDS total scores and ambivalent attachment style group (r=.0436, p=.000), and avoidant attachment style group (r=.328, p=.001). The level of perceived family support also showed a negative correlation with EPDS total score (r=-.363, p=.000). The regression of EPDS total score with ambivalent attachment style and state anxiety level are positively predicted and the level of perceived family support and existence of wider social network negatively predict the EPDS total score in the first postpartum week. Maternal attachment patterns, living with the extended family and existence of family support have an important impact on early postpartum emotional adaptation. Early intervention strategies should count towards these individual and contextual factors when designing screening and preventive interventions for postpartum depression
