Social Movements in the Age of Social Media: A Structural and Content-based Analysis

A wave of protest movements in recent years leveraging the potential of social media reveals the evolution in the process of collective identity in social networks, including the radical shift in the content and semantics of protest identity. The interplay of social media with social movements needs to be studied not only by illuminating the structural notion of networks in digital activism but also the actual content that flows through the medium such as the discourses and the iconographies pertaining to the social movement. With an aim to achieve this understanding, we propose a generic framework for the study of social media movements focusing on structure and content of social networks specifically characteristics such as homophily, structural capital and media richness along with the process of resource mobilization. We suggest a mixed-method approach to help answer the proposed research questions and validate the framework. The paper also discusses possible implications for research and practice.
Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa

Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation. The ROS and lipid peroxidation can be detected during preparation and cryopreservation of mammalian spermatozoa. The negative effects of ROS can be partially ameliorated by the action of antioxidants. The aims of this thesis were to 1) study the effects of antioxidants on cryopreserved epididymal spermatozoa from the domestic cats and to apply the results from domestic cats to cryopreserved wild felid ejaculated spermatozoa (flat-headed cats; Prionailurus planiceps) in Thailand; 2) detect lipid peroxidation and its effects on post-thaw epididymal cat spermatozoa and 3) evaluate basic seminal characteristics of captive flat-headed cats. In the first study, the semen extender was supplemented with two types of non-enzymatic antioxidants (cysteine and a water soluble vitamin E analogue Trolox). Vitamin E had positive effects on post-thaw sperm motility, progressive motility and membrane integrity. In the second study, centrifuged post-thaw epididymal cat spermatozoa were resuspended in media with or without egg yolk and with or without a transition metal (Fe2+) (which induces lipid peroxidation). Lipid peroxidation was measured by using a lipophilic dye probe (BODIPY581/591 C11). The results demonstrated that BODIPY581/591 C11 could be used to detect lipid peroxidation in cat spermatozoa. This reaction did not significantly increase during incubation unless induced by Fe2+. In the third study, enzymatic antioxidants (catalase, glutathione peroxidase; GPx and superoxide dismutase) were added to the semen extender. Lipid peroxidation was induced after thawing. Supplementation of GPx resulted in positive effects on post-thaw motility, linear motility, mitochondrial activity, membrane and DNA integrity. Although antioxidants had positive effects on sperm quality, the concentration of antioxidants used in this study did not reduce lipid peroxidation. In the last study, the basic seminal traits of captive flat-headed cats were evaluated, as were the effects of adding the vitamin E and GPx to the semen extender for flat-headed cat spermatozoa. The results demonstrated that the captive flat-headed cats were affected by teratozoospermia. The GPx had positive effects on the post-thaw quality of flat-headed cat spermatozoa in a similar manner to domestic cat sperm quality but it did not significantly affect in vtiro heterologous fertility tests. In conclusion, oxidative stress might be one of the factors causing damage during preservation of domestic and non-domestic cat spermatozoa. Post-thaw sperm quality was enhanced by the action of antioxidants.
Changing a Field of Change

School Psychology: A Blueprint for Training and Practice III (Ysseldyke et al., 2006) continues an over 20-year tradition of reenvisioning school psychology. This latest edition focuses with great clarity on school psychology as, ideally, a profession devoted to the prevention of school-based difficulties for children and capacity building for educational professionals. A reflection on Blueprint III is presented in this article using a brief overview of the history of consultation research as a backdrop to argue for more research attention to implementation realities in schools. These contexts, which change regularly based on characteristics of students, schools, teachers, and federal and state policy, may play a primary role in dictating service delivery patterns. Contextual forces may overwhelm even consultation models found to be effective in clinical trials—especially if school psychologists are not practicing skills that might ready systems for consultation. Further, school psychology training models may require scrutiny in the face of continuing challenges to establish a workforce capable of both knowing about and implementing consensual and evidence-based best practices. Finally, the expert practice of consultation by experienced school psychologists may be an underutilized source of information that should be tapped by consultation researchers who care about both identifying and disseminating efficacious practices into school settings.
Rhipicephalus turanicus, a new vector of Hepatozoon canis

SUMMARY The distribution of Hepatozoon canis mainly encompasses areas where its main tick vector, Rhipicephalus sanguineus sensu lato, is present. However, the detection of this pathogen in dogs, foxes and golden jackals well outside the areas inhabited by this tick species reinforced the hypothesis that additional ixodids are involved in the life cycle and transmission of this protozoon. The present study provides, for the first time, data supporting the sporogonic development of H. canis in specimens of Rhipicephalus turanicus collected from a naturally infected fox from southern Italy. The epidemiological role of R. turanicus as a vector of H. canis is discussed, along with information on the potential use of cell cultures for the experimental infection with H. canis sporozoites. The in vitro infection of canine leucocytes by sporozoites from ticks is proposed as a potential tool for future in-depth studies on the biology of H. canis.

Managing hypercholesterolemia and its correlation with carotid plaque morphology in patients undergoing carotid endarterectomy

Purpose: Hypercholesterolemia is a critical problem in patients with carotid atherosclerosis. The adequacy of attention to lipid risk factors in patients with carotid stenosis awaiting carotid endarterectomy (CEA) has rarely been studied. We also assessed patient awareness of hypercholesterolemia and carotid plaque morphology. Methods: A prospective study was conducted of 141 consecutive patients admitted electively for CEA. Each patient’s medical history was taken. Plasma cholesterol concentrations were determined. Plaque histology was scored according to American Heart Association criteria and their modification. Results: Of patients who were aware of their hypercholesterolemia and who were receiving treatment, 28.6% had total cholesterol levels ≥5 mmol/L. Among those patients who had been told that they had no problem with hypercholesterolemia, 32.5% had plasma cholesterol concentrations ≥5 mmol/L. Among those patients who had never had their plasma cholesterol measured, 48.4% had total cholesterol levels ≥5 mmol/L. Patients in this last group tended to have more severe types of plaque pathology than those in other groups (12.9% plaque rupture). Conclusions: Hypercholesterolemia does not seem to be well managed in patients awaiting CEA.
Effects of Linguistic Structure on Children's Ability to Isolate Initial Consonants

In 4 experiments, preschoolers and kindergarteners were asked to pronounce the initial consonants of spoken words. Children performed better on short words, such as bay, than on long words, such as bonus. Words with initial consonant clusters, such as brow, were more difficult for the children than words without initial consonant clusters, such as bar. A consonant cluster at the end of the word did not harm performance. Children did relatively well on words like suppose, for which the word's first syllable, /»/, constitutes a correct answer on the initial consonant isolation task. Children did more poorly on words like satin, for which this was not the case. Thus, the linguistic structure of a word affects children's ability to isolate the initial consonant. Implications for the design of phonemic awareness instruction are discussed. Children's ability to analyze spoken words into phonemes has received a good deal of attention from researchers and educators in recent years (see Adams, 1990; Brady & Shankweiler, 1991; Goswami & Bryant, 1990; Gough, Ehri, & Treiman, 1992; Rieben & Perfetti, 1991; Sawyer & Fox, 1991). The research reviewed in these volumes shows that phonemic awareness plays an important role in learning to read and write an alphabetic system. The research further shows that children who lack phonemic awareness skills are at risk for developing reading problems. On a more positive note, phonemic awareness can be taught. Such teaching improves children's reading and spelling performance. To design effective phonemic awareness instruction, detailed information about specific phonemic awareness tasks is needed. How do children perform these tasks? Do they do better with some kinds of words than others? Answers to these questions can help in the design of phonemic awareness instruction. For example, if some types of words are easier to analyze than others, the easy words can be taught first. Harder words can be introduced only after children have mastered the easier ones. The long-term goal of the research reported in this article is to improve phonemic awareness instruction, and ultimately reading, through the study of linguistic factors that affect children's performance in phonemic awareness tasks. Researchers and teachers have used a variety of phonemic awareness tasks. These include counting phonemes ("How many sounds do you hear in fishT), deleting phonemes ("Say fry without the/"), comparing phonemes ("Does dog end with
Platelet-activating factor: the biosynthetic and catabolic enzymes.

INTRODUCTION Several reviews [1-6] have covered various aspects of recent progress in the platelet-activating factor (PAF) field, but none of these has focused solely on the specific characteristics of the individual enzymes involved in the biosynthesis and catabolism of PAF and its analogues. The need for a quick source of such information is especially timely and pertinent, since during the past few years a number of new concepts have emerged about the close relationship between PAF biosynthesis and the trafficking of arachidonate and other polyenoates among membrane phospholipids via transacylation reactions [7-10]. Moreover, Lee et al. [11] have shown that PAF can serve as an acetate donor to
Optimality and Duality for Non-smooth Multiple Objective Semi-infinite Programming

The purpose of this paper is to consider a class of non-smooth multiobjective semi-infinite programming problem. Based on the concepts of local cone approximation, directional derivative and subdifferential, a new generalization of convexity, namely generalized uniform convexity, is defined for this problem. For such semi-infinite programming problem, several sufficient optimality conditions are established and proved by utilizing the above defined new classes of functions. The results extend and improve the corresponding results in the literature. Subsequently, these optimality conditions are utilized as a basis for formulating dual problems. Weak, strong and reverse duality theorems are also derived for Mond-Weir type multiobjective dual programs, using generalized invexity on the functions involved. Some previous duality results for differentiable multiobjective programming problems turn out to be special cases for the results described in the paper.
Renewed Global Partnerships and Redesigned Roadmaps for Rabies Prevention and Control

Canine rabies, responsible for most human rabies deaths, is a serious global public health concern. This zoonosis is entirely preventable, but by focusing solely upon rabies prevention in humans, this “incurable wound” persists at high costs. Although preventing human deaths through canine rabies elimination is feasible, dog rabies control is often neglected, because dogs are not considered typical economic commodities by the animal health sector. Here, we demonstrate that the responsibility of managing rabies falls upon multiple sectors, that a truly integrated approach is the key to rabies elimination, and that considerable progress has been made to this effect. Achievements include the construction of global rabies networks and organizational partnerships; development of road maps, operational toolkits, and a blueprint for rabies prevention and control; and opportunities for scaling up and replication of successful programs. Progress must continue towards overcoming the remaining challenges preventing the ultimate goal of rabies elimination.
Tangible windows for a free exploration of wide 3D virtual environment

Exploring virtual environment with immersive metaphor is still largely unexplored, with the costly CAVE exception. This question takes importance in lots of fields, such as fluid mechanics, where space and time resolved dataset become more and more common. For that reason, we present an interaction design study of an window exploration metaphor, for large 3D virtual environment. The metaphor is based on the use of a tablet as a tangible and movable window on a virtual environment. Rotations in the environment are tracker-less mapped on the rotations of the tablet. Our design is inspired by fluid mechanics issues, but is build keeping generalizability in mind. The study shows that mapping three degrees of freedom onto corresponding real three degrees of freedom of space raises the transparency, the efficiency of data exploration and the space awareness of users.
Lying: An Experimental Investigation of the Role of Situational Factors

ABSTRACT: Individuals often lie for psychological rewards (e.g., preserving self image and/or protecting others), absent economic rewards. We conducted a laboratory experiment, using a modified dictator game, to identify conditions that entice individuals to lie solely for psychological rewards. We argue that such lies can provide a ready means for individuals to manage others’ impression of them. We investigated the effect of social distance (the perceived familiarity, intimacy, or psychological proximity between two parties) and knowledge of circumstances (whether parties have common or asymmetric information) on the frequency of lying. We found that lying occurs more frequently when social distance is near and that the effect is exacerbated when information is asymmetric. Our theoretical development suggests that, under these conditions, individuals’ need to manage others’ impression is magnified. We discuss the implications of our findings.
Mobile Platform for Networked RFID Applications

RFID (radio-frequency identification) technology is widely used for supply chain management and inventory control. Furthermore, RFID has been recognized as a tool to realize a ubiquitous environment. The typical architecture of RFID applications comprises RFID tags, which are embedded in or attached to an object, an RFID reader, and IS (information services) server. The RFID reader reads the code in the RFID tag and interprets it by communicating with the IS server via a proper communication network. This is the typical architecture defined by EPCglobal. The RFID reader can be stationary or mobile. A mobile RFID reader affords more applications than the stationary one. In this paper, we describe the core components for realizing a mobile RFID application, such as a mobile RFID reader, platform architecture, and the corresponding network architecture. Although there are several types of mobile RFID readers in the market, we propose a specially designed mobile RFID technology that has several positive features including security, network architecture, operation scenario, and code resolution mechanism. Furthermore, we analyze the characteristics of the proposed technologies.
DNA replication and cell cycle control in Xenopus egg extracts

Summary Aspects of the regulation of DNA replication and mitosis have been studied using a cell-free extract of Xenopus eggs. The extract is characterized by repeated cycles of DNA replication and mitosis, which are accompanied by periodic synthesis and degradation of cyclins as well as fluctuations in the level of Histone H1 kinase activity. DNA replication in this system is dependent upon the formation of a nucleus. However, while nuclear structures are clearly required for initiation, a complete nuclear membrane does not appear to be necessary. Indirect immunofluorescence and DIC microscopy indicate that nuclear reformation from chromosomes occurs asynchronously around individual chromatids. Lamin polymerization, biotin-11-dUTP incorporation and association of polymerases with chromatin occur before membrane formation is complete. S phase nuclei are typified by the co-distribution of both anti-DNA polymerase α and anti-PCNA antibodies as discrete spots of fluorescence which align the chromatin. However, as DNA replication is terminated, PCNA fluorescence fades and DNA polymerase α dissociates from the chromatin and is redistributed throughout the nucleoplasm. By inhibiting DNA replication with aphidicolin, both DNA polymerase α and PCNA remain associated with the chromatin throughout prolonged incubation. Under these conditions mitosis is delayed by up to 70 min, although both the general rate of protein synthesis and more importantly the rate of cyclin synthesis and histone kinase activation are unaffected. Upon nuclear envelope breakdown and lamin dispersal, cyclins degrade; however, no chromosomes are formed, and both PCNA and DNA polymerase α remain associated with the chromatin. Also, histone kinase activity is maintained at elevated levels.
Modest Inflammation Enhances Diclofenac Hepatotoxicity in Rats: Role of Neutrophils and Bacterial Translocation

Idiosyncratic adverse drug reactions (IADRs) represent an important human health problem, yet animal models for preclinical prediction of these reactions are lacking. Recent evidence in animals suggests that some IADRs arise from drug interaction with an inflammatory episode that renders the liver sensitive to injury. Diclofenac (DCLF) is one of those drugs for which the clinical use is limited by idiosyncratic liver injury. We tested the hypothesis that modest inflammation triggered in rats by a small dose of lipopolysaccharide (LPS) renders a nonhepatotoxic dose of DCLF injurious to liver. Cotreatment of rats with nonhepatotoxic doses of LPS and DCLF resulted in elevated serum alanine aminotransferase activity and liver histopathologic changes 6 h after DCLF administration. Neither LPS nor DCLF alone had such an effect. Gene array analysis of livers revealed a unique gene expression pattern in the LPS/DCLF-cotreated group compared with groups given either agent alone. Antiserum-induced neutrophil (PMN) depletion in LPS/DCLF-cotreated rats protected against liver injury, demonstrating a role for PMNs in the pathogenesis of this LPS/DCLF interaction. Gut sterilization of LPS/DCLF-treated rats did not protect against liver injury. In contrast, gut sterilization did attenuate liver injury caused by a large, hepatotoxic dose of DCLF, suggesting that hepatotoxicity induced by large doses of DCLF is caused in part by its ability to increase intestinal permeability to endotoxin or other bacterial products. These results demonstrate that inflammation-DCLF interaction precipitates hepatotoxicity in rats and raise the possibility of creating animal models that predict human IADRs.
Sex roles and the school

Schools reflect the society which surrounds them but they must also be agents of change. When first published, this book argued that, for a variety of reasons, schools and other educational institutions enforce a set of gender roles more rigid than those current in wider society, leading to a repetitive pattern of under-achievement, particularly amongst working class girls. The last decade has seen an explosion of research on gender and education and, in this updated edition, Sara Delamont examines new research findings and strategies for change, continuing to argue that both sexes lose out from sexist schooling.
Incorporating model quality information in climate change detection and attribution studies

In a recent multimodel detection and attribution (D&A) study using the pooled results from 22 different climate models, the simulated “fingerprint” pattern of anthropogenically caused changes in water vapor was identifiable with high statistical confidence in satellite data. Each model received equal weight in the D&A analysis, despite large differences in the skill with which they simulate key aspects of observed climate. Here, we examine whether water vapor D&A results are sensitive to model quality. The “top 10” and “bottom 10” models are selected with three different sets of skill measures and two different ranking approaches. The entire D&A analysis is then repeated with each of these different sets of more or less skillful models. Our performance metrics include the ability to simulate the mean state, the annual cycle, and the variability associated with El Niño. We find that estimates of an anthropogenic water vapor fingerprint are insensitive to current model uncertainties, and are governed by basic physical processes that are well-represented in climate models. Because the fingerprint is both robust to current model uncertainties and dissimilar to the dominant noise patterns, our ability to identify an anthropogenic influence on observed multidecadal changes in water vapor is not affected by “screening” based on model quality.
Initial interaction of herpes simplex virus with cells is binding to heparan sulfate

We have shown that cell surface heparan sulfate serves as the initial receptor for both serotypes of herpes simplex virus (HSV). We found that virions could bind to heparin, a related glycosaminoglycan, and that heparin blocked virus adsorption. Agents known to bind to cell surface heparan sulfate blocked viral adsorption and infection. Enzymatic digestion of cell surface heparan sulfate but not of dermatan sulfate or chondroitin sulfate concomitantly reduced the binding of virus to the cells and rendered the cells resistant to infection. Although cell surface heparan sulfate was required for infection by HSV types 1 and 2, the two serotypes may bind to heparan sulfate with different affinities or may recognize different structural features of heparan sulfate. Consistent with their broad host ranges, the two HSV serotypes use as primary receptors ubiquitous cell surface components known to participate in interactions with the extracellular matrix and with other cell surfaces.
