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
Horsemastership part 3: international perspectives of its therapeutic value
No full textIn previous opinion articles written by the authors, it has been proposed that horsemastership is an effective medium for therapy and education for young adults with additional needs. However, the existing research to support this proposal is informal and limited. Therefore, the first author carried out an international piece of research into the value of horsemastership to this group of people. A questionnaire using both quantitative and qualitative methods was completed by 21 professionals of various disciplines and countries who used horsemastership for therapeutic and educational purposes. This article gives a brief description of the methodology, including justification for the design selected, and discusses the relevance and implications of the results of this study. To pull together the three articles written by the authors, a final conclusion on the value of horsemastership to people with additional needs is drawn.<br/
The effect of maternal body condition score before and during pregnancy on the glucose tolerance of adult sheep offspring
No full textThis study investigates the effects of diet-induced changes in maternal body condition on glucose tolerance in sheep. Welsh Mountain ewes were established, by dietary manipulation, at a body condition score of 2 (lower body condition [LBCS], n = 17) or >3 (higher body condition [HBCS], n = 19) prior to and during pregnancy. Birth weight and postnatal growth were similar in LBCS and HBCS offspring. In young adulthood, LBCS offspring had increased fasting glucose levels (3.8 +/- 0.07 vs 3.6 +/- 0.05 mM, P < .05), poorer glucose tolerance (2274 +/- 22.6 vs 2161 +/- 33 min/mM, P < .01), and reduced insulin secretion (0.58 +/- 0.05 vs 0.71 +/- 0.07 nM/min, P = .07). Increased fasting glycemia, mild glucose intolerance, and impaired initial insulin secretory response, as observed in LBCS offspring, are indictors of increased diabetes risk in humans. These findings suggest that altered maternal body composition and an imbalance between the fetal and postnatal environment influence offspring glucose tolerance
Effect of maternal diet and body condition on glucose metabolism and skeletal muscle structure in mature adult sheep offspring
No full textEarly life nutrition is implicated in the risk of metabolic diseases (e.g. type 2 diabetes) in adulthood. Low birth-weight was associated with defects in the skeletal muscle insulin-signalling pathway of young adult men (1), and insulin resistance was associated with changes in myofibre composition (2). In sheep, maternal undernutrition reduced fetal skeletal muscle myofibre density and composition (3). Recently we reported that lower body condition score (BCS) led to increased fasting glycaemia, mild glucose intolerance and impaired initial insulin secretory response in adult offspring (4). We hypothesised that this would worsen with age, and that altered skeletal muscle structure and insulin signalling pathways are involved. Ewes were established, by dietary manipulation, at a BCS of 2 (lower (L) n = 10) or >3 (higher (H) n = 14) before and during pregnancy (4). In male offspring at 4.04±0.02 years plasma glucose and insulin concentrations were measured during a glucose tolerance test (0.5 g/kg body weight i.v.) and rams were killed by an overdose of barbiturate (i.v. 145 mg/kg). We analysed a) insulin-signalling proteins by Western blotting in abdominal fat and vastus muscle (m.); b) glucose uptake in isolated strips of vastus and soleus m.(5); c) myofibre density and cross-sectional area (CSA) by immunostaining with anti-fast skeletal myosin (3). Data are mean±SE and were analysed by Student’s t test. Glucose tolerance was similar between groups. Basal glucose uptake was similar in L and H group soleus and vastus m. isolated strips. However insulin-stimulated uptake tended to be reduced in the soleus m. only of L rams (H 1.01±0.06; L 0.84±0.07 pmol.min.mg, p<0.1). In vastus, but not soleus, m. total myofibre density (H 343±15; L 294±14 fibres/mm2, p<0.05) and fast myofibre density (H 226±10; L 194±10 fibres/mm2, p<0.05) was lower in L rams. Slow myofibre density tended to be lower in L rams (H 117±7; L 100±6 fibres/mm2, p<0.1). Myofibre CSA was unaltered. Protein levels of (i) Akt1 were lower in the vastus m. (L=83±7% of H, p<0.05), and tended to be lower in abdominal fat (L=71±7% of H, p<0.1), of L rams; (ii) GLUT-4 were increased (L=157±6% of H, p<0.001), and (iii) IGF-IR tended to be reduced (L=78±12% of H, p<0.1), in the vastus m. of L rams. Reduced signalling through Akt1 may therefore mediate the decreased vastus m. myofibre density in L rams resulting in reduced glucose tolerance of the young adult offspring (4). However in mature adulthood, glucose tolerance and glucose uptake into vastus m. was not altered by maternal BCS, and thus the impact of reduced myofibre density may be offset in part by increased GLUT-4. Such adaptations may lead to complications in metabolic control in an overabundant postnatal nutrient environment
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)

Development of a field repair technique for mini-sandwich Kevlar/epoxy aircraft skin.
No full textAn experimental analysis was performed on Kevlar/epoxy
cloth "mini-sandwich" panels with cellular foam core. Three
undamaged panels and twenty-three other panels with damage
and repairs were subjected to static shear loading. Four
parameters were varied in the types of repairs; hole size,
hole plug filler material, patch material, and patch overlap
distance. All twenty-six panels were tested to failure. A
repair technique employing a cellular foam plug and fiberglass
patches overlapping the original hole by 0.50 inches,
symmetrically applied with structural adhesive, was found to
be suitable for repair cf up to three inch diameter circular
holes at field repair level. Additionally, postbuckling
energy absorption was Qualitatively examined for undamaged
panels and for hole sizes ranging from 1.00 to 5.00 inches
diameter.Approved for public release; distribution is unlimited.Captain, United States Armyhttp://archive.org/details/developmentoffie109451925

Secure signal processing: Privacy preserving cryptographic protocols for multimedia
No full textRecent advances in technology provided a suitable environment for the people in which they can benefit from online services in their daily lives. Despite several advantages, online services also constitute serious privacy risks for their users as the main input to algorithms are privacy sensitive such as demographic information, shopping patterns, medical records, etc. While traditional security mechanisms can eliminate a number of attacks from outside, these mechanisms can not protect the privacy of the users as the service provider itself constitutes the biggest potential risk. In this thesis, we focus on principled solutions to protect the privacy of users in multimedia applications. For this purpose we propose to keep the privacy-sensitive data safe by means of encryption during processing. This approach eliminates the risk of possible privacy abuse as the sensitive data is only available to the owner but no other party. However, once encrypted, the structure in data is destroyed as a consequence of the encryption procedure and thus we need appropriate tools to process encrypted data. Therefore, we focus on a number of cryptographic tools such as homomorphic encryption schemes and multiparty computation (MPC) techniques to realize privacy-preserving multimedia applications. The proposed principled solutions consider the signal processing aspect of the multimedia applications which is a new idea to the best of our knowledge. In particular, we focus on a number of prototypical applications namely, face detection, user clustering in a social network, recommendation generation and anonymous fingerprinting. Based on these selected applications, we addressed the major challenges for secure signal processing: data representation, data expansion, realizing linear and non-linear operations and efficiency of the proposed protocols in terms of communication and computational costs. We propose to scale and round the signal values prior to encryption as these operations are highly inefficient to be realized in the encrypted domain. Moreover, we reserve sufficient space in terms of bit length for each signal sample to accommodate the possible expansion in bit size in the subsequent processing steps. However, reserving more bits for signals does not contradict with the data expansion problem. As the cipher text space is much larger than the size of the original -- and even scaled -- signal samples, data expansion after encryption increases data transmission and storage costs significantly. In order to minimize the cost we propose to pack a number of signal samples in one encryption and process them when they are in the packed form. This approach requires cryptographic protocols particularly designed for the packed data but in the end saves considerable resources regarding bandwidth and storage capacity, even computational power. Homomorphism plays a crucial role in our proposed solutions. With the help of homomorphic encryption, we are able to implement linear operations such as correlation and projection without interaction. However, linear operations are only a part of the signal processing. For the non-linear operations like distance computation, thresholding and comparison, we exploit MPC techniques. These techniques are often interactive and computationally expensive compared to the original systems in plain. However, by using data packing and designing the protocols with care, the communication and computational costs were reduced significantly. In this thesis, we have shown that preserving privacy for multimedia signal processing is feasible. We determined the major challenges of secure signal processing and combined a set of cryptographic tools successfully with signal processing to realize the applications in the encrypted domain. The proposed solutions demonstrate that the privacy concerns in multimedia signal processing applications can be coped with by using cryptographic tools. Moreover, protocols that are designed to realize certain operations in the encrypted domain can be used in other applications and settings with a number of modifications.MediamaticsElectrical Engineering, Mathematics and Computer Scienc
