Strengths and Weaknesses of Anthropology and Political Science in Observing Nationalism: The Case of Cyprus (1968-1977)

Abstract This paper reflects the results of a Political Science research that investigated the re-construction ofGreek Cypriot national identity in 1968-1977. It utilized a qualitative methodology and conducted a documentaryresearch. It also followed a deductive approach and tested the validity of theoretical approaches, arguing thatnational identities and nationalism politics are constructed based on economic and political interests. Even thoughthe data gathered supported the validity of these approaches for the studied case, the research remained insufficientin accounting for the roles of language, ethno-symbols and collective memories in shaping national identities. Thepaper discusses its results based on the strengths and weaknesses of Political Science, and Sociocultural Anthropology,in studies of nationalism and national identity.
The Quest for the FFA and Where It Led

This article tells the story behind our first paper on the fusiform face area (FFA): how we chose the question, developed the methods, and followed the data to find the FFA and subsequently many other functionally specialized cortical regions. The paper's impact had less to do with the particular findings in the paper itself and more to do with the method that it promoted and the picture of the human mind and brain that it led to. The use of a functional localizer to define a candidate region in each subject individually enabled us not just to make pictures of brain activation, but also to ask principled, hypothesis-driven questions about a thing in nature. This method enabled stronger and more extensive tests of the function of each cortical region than had been possible before in humans and, as a result, has produced a large body of evidence that the human cortex contains numerous regions that are specifically engaged in particular mental processes. The growing inventory of cortical regions with distinctive and often very specific functions can be seen as an initial sketch of the basic components of the human mind. This sketch also serves as a roadmap into the vast and exciting new landscape of questions about the computations, structural connections, time course, development, plasticity, and evolution of each of these regions, as well as the hardest question of all: how do these regions work together to produce human intelligence?
Effects of acute increases in left ventricular preload on indices of myocardial function in conscious, unrestrained and intact, tranquilized baboons.

The effects of acute volume loading were examined on indices of left ventricular (LV) function in conscious, unrestrained and intact, tranquilized baboons. Experiments were conducted 1-3 mo after implantation of ultrasonic transducers to measure LV internal diameter and wall thickness, and miniature LV pressure gauges and aortic and left atrial catheters. In 10 intact, tranquilized baboons, rapid volume loading with saline increased LV end-diastolic pressure by 23.7+/-2.6 mm Hg, LV end-diastolic diameter by 7.8+/-1.5%, LV stroke work by 37.5+/-7.8%, while mean arterial pressure and peak LV wall stress did not change significantly. Despite the increase in preload and activation of the Frank-Starling mechanism, LV dP/dt(max) and the maximum velocity of myocardial fiber shortening (LV dD/dt(max)) did not change. Volume loading after beta-adrenergic or combined beta-adrenergic and cholinergic blockades or volume loading with blood instead of saline also failed to augment LV dP/dt(max) and LV dD/dt(max) despite the increase in preload. In order to volume load the baboons in the conscious state, a radiofrequency (RF) interrogator system was devised, which upon receipt of a radio command, activated a battery operated pump to infuse 1,000 ml of saline i.v. to the baboons. In these experiments, preload rose, i.e., LV end-diastolic diameter increased by 13.9+/-2.1% and the Frank-Starling mechanism could be demonstrated, i.e., stroke work rose by 42.8+/-7.4%, but LV dP/dt(max) and LV dD/dt(max) did not change. After preload was depressed by hemorrhage, the rapid infusion of either blood or saline increased LV dP/dt(max) by 92.7+/-18.5% and LV dD/dt(max) by 64.3+/-10.1%. Thus, acute volume loading in the conscious baboons increased LV end-diastolic size and even stroke work substantially. However, preload dependency of LV dP/dt(max) and the maximum velocity of myocardial fiber shortening was only encountered at low levels of LV preload.
Preventing drive-by download via inter-module communication monitoring

Drive-by download attack is one of the most severe threats to Internet users. Typically, only visiting a malicious page will result in compromise of the client and infection of malware. By the end of 2008, drive-by download had already become the number one infection vector of malware [5]. The downloaded malware may steal the users' personal identification and password. They may also join botnet to send spams, host phishing site or launch distributed denial of service attacks. Generally, these attacks rely on successful exploits of the vulnerabilities in web browsers or their plug-ins. Therefore, we proposed an inter-module communication monitoring based technique to detect malicious exploitation of vulnerable components thus preventing the vulnerability being exploited. We have implemented a prototype system that was integrated into the most popular web browser Microsoft Internet Explorer. Experimental results demonstrate that, on our test set, by using vulnerability-based signature, our system could accurately detect all attacks targeting at vulnerabilities in our definitions and produced no false positive. The evaluation also shows the performance penalty is kept low.
Role for hACF1 in the G2/M damage checkpoint

Active chromatin remodelling is integral to the DNA damage response in eukaryotes, as damage sensors, signalling molecules and repair enzymes gain access to lesions. A variety of nucleosome remodelling complexes is known to promote different stages of DNA repair. The nucleosome sliding factors CHRAC/ACF of Drosophila are involved in chromatin organization during development. Involvement of corresponding hACF1-containing mammalian nucleosome sliding factors in replication, transcription and very recently also non-homologous end-joining of DNA breaks have been suggested. We now found that hACF1-containing factors are more generally involved in the DNA damage response. hACF1 depletion increases apoptosis, sensitivity to radiation and compromises the G2/M arrest that is activated in response to UV- and X-rays. In the absence of hACF1, γH2AX and CHK2ph signals are diminished. hACF1 and its ATPase partner SNF2H rapidly accumulate at sites of laser-induced DNA damage. hACF1 is also required for a tight checkpoint that is induced upon replication fork collapse. ACF1-depleted cells that are challenged with aphidicolin enter mitosis despite persistence of lesions and accumulate breaks in metaphase chromosomes. hACF1-containing remodellers emerge as global facilitators of the cellular response to a variety of different types of DNA damage.
Asymmetric self-learning for tackling Twitter Spam Drift

Spam has become a critical problem on Twitter. In order to stop spammers, security companies apply blacklisting services to filter spam links. However, over 90% victims will visit a new malicious link before it is blocked by blacklists. To eliminate the limitation of blacklists, researchers have proposed a number of statistical features based mechanisms, and applied machine learning techniques to detect Twitter spam. In our labelled large dataset, we observe that the statistical properties of spam tweets vary over time, and thus the performance of existing ML based classifiers are poor. This phenomenon is referred as “Twitter Spam Drift”. In order to tackle this problem, we carry out deep analysis of 1 million spam tweets and 1 million non-spam tweets, and propose an asymmetric self-learning (ASL) approach. The proposed ASL can discover new information of changed tweeter spam and incorporate it into classifier training process. A number of experiments are performed to evaluate the ASL approach. The results show that the ASL approach can be used to significantly improve the spam detection accuracy of using traditional ML algorithms.
TR-CIS-06-18 Security Protocols with Isotropic Channels

We investigate the security properties of isotropic channels, broadcast media in which a receiver cannot reliably determine whether a message originated from any particular sender and a sender cannot reliably direct a message away from any particular receiver. We show that perfect isotropism implies perfect (informationtheoretic) secrecy, and that asymptotically close to perfect secrecy can be achieved on any channel that provides some (bounded) uncertainty as to sender identity. We give isotropic security protocols under both passive and active adversary models, and discuss the practicality of realizing isotropic channels over various media.
Malaria Cell Counting Diagnosis within Large Field of View

Malaria is one of the most serious parasitic infections of human. The accurate and timely diagnosis of malaria infection is essential to control and cure the disease. Some image processing algorithms to automate the diagnosis of malaria on thin blood smears are developed, but the percentage of parasitaemia is often not as precise as manual count. One reason resulting in this error is ignoring the cells at the borders of images. In order to solve this problem, a kind of diagnosis scheme within large field of view (FOV) is proposed. It includes three steps. The first step is image mosaicing to obtain large FOV based on space-time manifolds. The second step is the segmentation of erythrocytes where an improved Hough Transform is used. The third step is the detection of nucleated components. At last, it is concluded that the counting accuracy of malaria infection within large FOV is finer than several regular FOVs.
Drosophila RecQ4 Is Directly Involved in Both DNA Replication and the Response to UV Damage in S2 Cells

The RecQ4 protein shows homology to both the S.cerevisiae DNA replication protein Sld2 and the DNA repair related RecQ helicases. Experimental data also suggest replication and repair functions for RecQ4, but the precise details of its involvement remain to be clarified. Here we show that depletion of DmRecQ4 by dsRNA interference in S2 cells causes defects consistent with a replication function for the protein. The cells show reduced proliferation associated with an S phase block, reduced BrdU incorporation, and an increase in cells with a subG1 DNA content. At the molecular level we observe reduced chromatin association of DNA polymerase-alpha and PCNA. We also observe increased chromatin association of phosphorylated H2AvD - consistent with the presence of DNA damage and increased apoptosis. Analysis of DmRecQ4 repair function suggests a direct role in NER, as the protein shows rapid but transient nuclear localisation after UV treatment. Re-localisation is not observed after etoposide or H2O2 treatment, indicating that the involvement of DmRecQ4 in repair is likely to be pathway specific. Deletion analysis of DmRecQ4 suggests that the SLD2 domain was essential, but not sufficient, for replication function. In addition a DmRecQ4 N-terminal deletion could efficiently re-localise on UV treatment, suggesting that the determinants for this response are contained in the C terminus of the protein. Finally several deletions show differential rescue of dsRNA generated replication and proliferation phenotypes. These will be useful for a molecular analysis of the specific role of DmRecQ4 in different cellular pathways.
Comparative Efficacy of Silver-Containing Dressing Materials for Treating MRSA-Infected Wounds in Rats with Streptozotocin-Induced Diabetes.

OBJECTIVE Silver plays an important part in severe wound management, mainly by reducing microbial growth within dressed wounds and wound beds. However, it is unknown how silver-coated dressing materials affect diabetic wounds. The purpose of this study is to evaluate the efficacy of silver-containing dressing materials for the treatment of methicillin-resistant Staphylococcus aureus (MRSA)-infected wounds in streptozotocininduced diabetic rats. METHODS Full-thickness skin defects were created on the backs of rats with streptozotocin (STZ)-induced diabetes (n = 108) and were infected with MRSA. The rats were assigned to 6 groups according to the wound dressing used: nanocrystalline silver (Acticoat, Smith & Nephew, Inc, London, UK), silver carboxymethylcellulose (Aquacel-Ag, ConvaTec, Skillman, NJ), silver sulfadiazine (Medifoam silver, Genewel Science Co Ltd, Seongnam, South Korea), nanocrystalline silver (Poly- Mem silver, Ferris Mfg Corp, Burr Ridge, IL), silver sulfadiazine (Ilvadon, Ildong Pharmaceuticals, Seoul, South Korea), and 10% povidone iodide (control). The wound size, histological findings, and bacterial colony count for each group was analyzed and compared to normal Sprague-Dawley rats. RESULTS Wound size decreased over time in every group. On day 10, a significant difference in wound area was detected between the silver dressing groups and the control group (P = 0.0040). In the wound biopsy, on days 4, 7, and 10, the would-healing effect increased in every group. However, between days 4 (P = 0.8250) and 10 (P = 0.9912), there was no statistical difference between groups. The number of bacteria in each group decreased with time in the bacterial wound culture. The silver dressing groups were more effective on antimicrobial efficacy, but there was no statistically significant difference between the silver dressing groups and the control group. CONCLUSION Silver-containing dressing materials are an effective method for MRSA-infected wounds, but nano silver-containing dressing materials did not have better results in a diabetic rat model compared to a normal rat model in historical review. Further investigation is necessary to determine the relative safety of these products on the healing wound. Once that is done, the relative value of the products can be determined by balancing their antimicrobial and cytotoxicity characteristics.
Factors Associated with Development of Speech Perception Skills in Children Implanted by Age Five

Objective This study investigated factors contributing to speech perception outcomes in children with prelingual deafness after 4 to 7 yr of multichannel cochlear implant use. The analysis controlled for the effects of child, family and implant characteristics so that educational factors most conducive to maximum implant benefit could be identified. Design One hundred eighty-one 8- and 9-yr-old children from across the US and Canada who received a cochlear implant by age 5 were administered a battery of speech perception tests. Type and amount of educational intervention since implantation constituted the independent variables. Characteristics of the child, the family, and the implant itself constituted intervening variables. A series of multiple regression analyses determined the amount of variance in speech perception ability accounted for by the intervening variables and the amount of additional variance attributable to independent variables. Results The children achieved an average level of about 50% open-set speech perception through listening alone and almost 80% through lipreading and listening together, but with scores for individual children ranging from 0 to 100% correct. Over half of the variance in speech perception scores was predicted by characteristics of the child, family, implant and educational program. Significant predictors of good speech perception included greater nonverbal intelligence, smaller family size, longer use of the updated SPEAK/CIS processing strategy, a fully active electrode array, greater electrical dynamic range between threshold and maximum comfort level, and greater growth of loudness with increasing stimulus intensity. After the variance due to these variables was controlled, the primary rehabilitative factor associated with good speech perception skill development was educational emphasis on oral-aural communication. Conclusions Children with profound hearing loss achieved unprecedented levels of speech perception skill 4 to 7 yr after cochlear implantation. Use of an updated speech processor, such as SPEAK, contributed significantly to improved speech perception skills, even in children who were initially fitted with an earlier strategy, such as M-PEAK. In addition, the audiologist who programs the cochlear implant makes an important contribution to the child’s successful outcome with the device. A well-fitted map, as evidenced by a wide dynamic range and optimal growth of loudness characteristics, contributed substantially to the child’s ability to hear speech. Finally, the classroom communication mode used in the child’s school affects speech perception outcome. Children whose educational program emphasized dependence on speech and audition for communication were better able to use the information provided by the implant to understand speech.
Controlling elections with bounded single-peaked width

The problems of controlling an election have been shown NP-complete in general but polynomial-time solvable in single-peaked elections for many voting correspondences. To explore the complexity border, we consider these control problems by adding/deleting votes in elections with bounded single-peaked width k. Single-peaked elections have single-peaked width k=1. We prove that the constructive control problems for Copelandα with 0≤α<1 turn out to be NP-hard even with k=2, while for Copeland1 and Maximin, the constructive control problems remain polynomial-time solvable with k=2 but become NP-hard with k=3. In contrast, we show that the constructive control problems for Condorcet and weak Condorcet and the destructive control problems for Maximin and Copelandα with 00≤α≤1 are all polynomial-time solvable with k being a constant; more precisely, these problems are fixed-parameter tractable (FPT) with k as parameter. A byproduct of our results is that the Young winner determination problem is FPT with respect to k. Finally, for the class of voting correspondences passing the Smith-IIA criterion we provide a general characterization to identify voting correspondences whose control problems are FPT with respect to k.
Wnt/Calcium Signaling Mediates Axon Growth and Guidance in the Developing Corpus Callosum

It has been shown in vivo that Wnt5a gradients surround the corpus callosum and guide callosal axons after the midline (postcrossing) by Wnt5a‐induced repulsion via Ryk receptors. In dissociated cortical cultures we showed that Wnt5a simultaneously promotes axon outgrowth and repulsion by calcium signaling. Here to test the role of Wnt5a/calcium signaling in a complex in vivo environment we used sensorimotor cortical slices containing the developing corpus callosum. Plasmids encoding the cytoplasmic marker DsRed and the genetically encoded calcium indicator GCaMP2 were electroporated into one cortical hemisphere. Postcrossing callosal axons grew 50% faster than pre‐crossing axons and higher frequencies of calcium transients in axons and growth cones correlated well with outgrowth. Application of pharmacological inhibitors to the slices showed that signaling pathways involving calcium release through IP3 receptors and calcium entry through TRP channels regulate post‐crossing axon outgrowth and guidance. Co‐electroporation of Ryk siRNA and DsRed revealed that knock down of the Ryk receptor reduced outgrowth rates of postcrossing but not precrossing axons by 50% and caused axon misrouting. Guidance errors in axons with Ryk knockdown resulted from reduced calcium activity. In the corpus callosum CaMKII inhibition reduced the outgrowth rate of postcrossing (but not precrossing) axons and caused severe guidance errors which resulted from reduced CaMKII‐dependent repulsion downstream of Wnt/calcium. We show for the first time that Wnt/Ryk calcium signaling mechanisms regulating axon outgrowth and repulsion in cortical cultures are also essential for the proper growth and guidance of postcrossing callosal axons which involve axon repulsion through CaMKII. © 2010 Wiley Periodicals, Inc.

‘The New Order of Things’: Immobility as protection in the regime of immigration controls

In this paper, I discuss two 1835 ordinances passed by the local council of the British colony of Mauritius. Passed shortly after Britain’s 1833 Slavery Abolition Act, these restrictions initiated the regulation and restriction of immigration within the British Empire. Seen as quite novel in their day, these ordinances employed the rhetoric of ‘protecting emigrants’ to legitimise the new constraints they imposed on free human mobility. Today, when the national ‘logic of constraint’ on human mobility is almost uncontested, the idea that immigration controls protect migrants remains central to the discursive practices concerning human trafficking. Nation-state constraints on human mobility are normalised while the exploitation and abuse of people on the move is ideologically redirected to ‘modern-day slavers’ or ‘evil traffickers’, thus absolving both the state and globally operative capital of their culpability.
Patterns of Synonymous Codon Usage on Human Metapneumovirus and Its Influencing Factors

Human metapneumovirus (HMPV) is an important agent of acute respiratory tract infection in children, while its pathogenicity and molecular evolution are lacking. Herein, we firstly report the synonymous codon usage patterns of HMPV genome. The relative synonymous codon usage (RSCU) values, effective number of codon (ENC) values, nucleotide contents, and correlation analysis were performed among 17 available whole genome of HMPV, including different genotypes. All preferred codons in HMPV are ended with A/U nucleotide and exhibited a great association with its high proportion of these two nucleotides in their genomes. Mutation pressure rather than natural selection is the main influence factor that determines the bias of synonymous codon usage in HMPV. The complementary pattern of codon usage bias between HMPV and human cell was observed, and this phenomenon suggests that host cells might be also act as an important factor to affect the codon usage bias. Moreover, the codon usage biases in each HMPV genotypes are separated into different clades, which suggest that phylogenetic distance might involve in codon usage bias formation as well. These analyses of synonymous codon usage bias in HMPV provide more information for better understanding its evolution and pathogenicity.
Language identification of names with SVMs

The task of identifying the language of text or utterances has a number of applications in natural language processing. Language identification has traditionally been approached with character-level language models. However, the language model approach crucially depends on the length of the text in question. In this paper, we consider the problem of language identification of names. We show that an approach based on SVMs with n-gram counts as features performs much better than language models. We also experiment with applying the method to pre-process transliteration data for the training of separate models.
