An infinite supermultiplet of massive higher-spin fields

The representation theory underlying the inflnite-component relativistic wave equation written by Majorana is revisited from a modern perspective. On the one hand, the massless solutions of this equation are shown to form a supermultiplet of the superPoincare algebra with tensorial central charges; it can also be obtained as the inflnite spin limit of massive solutions. On the other hand, the Majorana equation is generalized for any space-time dimension and for arbitrary Regge trajectories. Inspired from these results, an inflnite supermultiplet of massive flelds of all spins and of equal mass is constructed in four dimensions and proved to carry an irreducible representation of the orthosymplectic group OSp(1j4) and of the superPoincargroup with tensorial charges.
Nicotine induces intracellular Ca 2+ increases in cultured hippocampal astrocytes by nAChR-dependent and -independent pathways

Nicotine, the major addictive substance in tobacco, interacts with nicotinic acetylcholine receptors (nAChRs) located in neuronal and glial cells, modulating synaptic transmission and memory. Here, we show that nAChRs agonists, including nicotine, acetylcholine, and choline, increase the intracellular Ca2+ concentration ([Ca2+]i) in cultured hippocampal astrocytes, indicating the involvement of nAChRs. Interestingly, inhibition of nAChRs, with a cocktail of antagonists (mecamylamine, methyllycaconitine plus dihydro-β- erythroidine), does not prevent the astrocytic [Ca2+]i increases generated by nicotine. This last effect would be attributable to inhibition of K+ currents by nicotine in these cells, as previously we showed using patch- clamp recordings. Furthermore, the application of tetraethylammonium, an inhibitor of K+ currents, also increases the [Ca2+]i. Together, these results indicate that nicotine increases [Ca2+]i in hippocampal astrocytes through two pathways: by activation of nAChRs, and likely by direct inhibition of K+ currents.
Hizmetiçi Eğitimin Örgütsel Özdeşleşme ve İşten Ayrılma Niyetine Etkisi: Antalya daki Beş Yıldızlı Otel İşletmeleri Örneği (The Effect of Service Training on Organizational Identification and Intention to Leave: A Case Study on Five Star Hotels in Antalya)

Turizm sektöründe insan emeğinin ön planda olması, otel işletmelerinde çalışanların nitelikli olmasını gerekli kılmaktadır. Bu nedenle, çalışanlara uygulanan hizmetiçi eğitim önemli bir unsur olmaktadır. Otel işletmelerinde çalışanlara verilen hizmetiçi eğitimler misafir ve çalışan memnuniyeti sağlarken, çalışanlarında örgütle özdeşleşme düzeylerine etki ederek işten ayrılma niyetlerini azaltmaktadır. Bu doğrultuda çalışmanın amacı otel işletmelerinde verilen hizmetiçi eğitimin, çalışanların örgütsel özdeşleşme ve işten ayrılma niyetine etkisini belirlemektir. Bu amaç doğrultusunda veri toplamak amacıyla Antalya’da hizmetiçi eğitim uygulayan beş yıldızlı otel işletmelerinde çalışan 501 işgören üzerinde anket uygulanmıştır. Araştırmada verilerin analizinde ilişki ölçüm testlerinden korelasyon ve regresyon analizleri kullanılmıştır. Araştırma sonucunda; hizmetiçi eğitim ile örgütsel özdeşleşme ve işten ayrılma niyeti arasında anlamlı bir ilişkinin olduğu tespit edilmiştir. Bununla birlikte, beş yıldızlı otel işletmelerinde verilen hizmetiçi eğitimin çalışanların örgütsel özdeşleşme düzeyleri üzerine pozitif yönlü, işten ayrılma niyetleri üzerine ise negatif yönlü etkisi olduğu sonucuna ulaşılmıştır.
Biomechanics of Interspinous Devices

A number of interspinous devices (ISD) have been introduced in the lumbar spine implant market. Unfortunately, the use of these devices often is not associated with real comprehension of their biomechanical role. The aim of this paper is to review the biomechanical studies about interspinous devices available in the literature to allow the reader a better comprehension of the effects of these devices on the treated segment and on the adjacent segments of the spine. For this reason, our analysis will be limited to the interspinous devices that have biomechanical studies published in the literature.
Quadruplex formation by both G-rich and C-rich DNA strands of the C9orf72 (GGGGCC)8•(GGCCCC)8 repeat: effect of CpG methylation

Unusual DNA/RNA structures of the C9orf72 repeat may participate in repeat expansions or pathogenesis of amyotrophic lateral sclerosis and frontotemporal dementia. Expanded repeats are CpG methylated with unknown consequences. Typically, quadruplex structures form by G-rich but not complementary C-rich strands. Using CD, UV and electrophoresis, we characterized the structures formed by (GGGGCC)8 and (GGCCCC)8 strands with and without 5-methylcytosine (5mCpG) or 5-hydroxymethylcytosine (5hmCpG) methylation. All strands formed heterogenous mixtures of structures, with features of quadruplexes (at pH 7.5, in K+, Na+ or Li+), but no feature typical of i-motifs. C-rich strands formed quadruplexes, likely stabilized by G•C•G•C-tetrads and C•C•C•C-tetrads. Unlike G•G•G•G-tetrads, some G•C•G•C-tetrad conformations do not require the N7-Guanine position, hence C9orf72 quadruplexes still formed when N7-deazaGuanine replace all Guanines. 5mCpG and 5hmCpG increased and decreased the thermal stability of these structures. hnRNPK, through band-shift analysis, bound C-rich but not G-rich strands, with a binding preference of unmethylated > 5hmCpG > 5mCpG, where methylated DNA-protein complexes were retained in the wells, distinct from unmethylated complexes. Our findings suggest that for C-rich sequences interspersed with G-residues, one must consider quadruplex formation and that methylation of quadruplexes may affect epigenetic processes.
Repositioning the Culture of Power: Advocating for Systemic Change in Public Affairs Education

Abstract The present study sets out to characterize and analyze difficulties that typically face faculty of color who teach at Predominantly White Institutions (PWIs). Using personal narratives of junior faculty at a PWI, we explore the themes of shifting identity and marginality for faculty of color as these intersect with the presentation of public selves in university settings. This exploration is consistent with development of the themes of intersectionality and multiplicity in the work of Rivera and Ward in their Spring, 2008 Social Equity and Diversity symposium (2008). We as authors were initially unsure whether the effort to analyze concerns surrounding multiple identities in a PWI was an act of empowerment, or a strategic response to a work setting where some refused to recognize us as we defined ourselves. Building on this framing question and a review of pertinent literature, we set out to explore how the institutional context shapes our identities as faculty of color. Ultimately, we argue that, in addition to creating inclusive strategies for faculty of color at this level, in order to empower them the PWI must also engage in a critique of the culture of power that still prevails in higher-education institutions.
Simulation of singularities and instabilities arising in thin film flow

We present a finite element scheme for nonlinear fourth-order diffusion equations that arise for example in lubrication theory for the time evolution of thin films of viscous fluids. The equations are in general fourth-order degenerate parabolic, but in addition singular terms of second order may occur which model the effects of intermolecular forces or thermocapillarity. Discretizing the arising nonlinearities in a subtle way allows us to establish discrete counterparts of the essential integral estimates found in the continuous setting. As a consequence, the algorithm is efficient, and results on convergence, nonnegativity or even strict positivity of discrete solutions follow in a natural way. Applying this scheme to the numerical simulation of different models shows various interesting qualitative effects, which turn out to be in good agreement with physical experiments.
The Determinants of Audit Fees - Evidence from the Voluntary Sector

Given the growing demand for accountability in the public sector, there is a need to begin to investigate audit pricing issues in markets within this sector. This study makes three principal contributions. First, it develops and estimates, for the first time, a model of audit fee determinants relevant to the charity sector. The model is based on 210 of the top 500 UK charities with average incoming resources of 27 million pounds. As in previous private sector company studies, size, organisational complexity and audit firm location are the major determinants. A positive association between audit fees and fees for non-audit services is also observed. Charity sector factors of empirical significance include the fundamental nature of the charity (i.e., predominantly grant-making or fund-raising), the importance of trading as a source of charity income and the charity's activity. Separate models are developed for grant-making and fund-raising charities, the results reflecting the relative complexity of the audit of fund-raising charities. Second, the lower auditor concentration in the charity sector market, compared to the private sector market, permits a more powerful test of whether large firms and/or auditor expertise are rewarded with a fee premium. The results show that Big 6 audit firms receive higher audit fees (18.5%, on average) than non-Big 6 firms for audits of fund-raising charities. There is also evidence that non-Big 6 audit firms with expertise in the sector are rewarded with a fee premium over other non-Big 6 firms, again in the more complex audit environment of fund-raising charities. Finally, the study demonstrates that the charity audit fee rate is significantly lower than that of private sector companies; in fact it is approximately half. Further research that discriminates between alternative explanations of this differential is called for. A change in the reporting of charity audit fees is proposed to reflect any element of 'charitable giving' by the audit firm.
An SIRS Epidemiological Model with Nonlinear Incidence Rate Incorporating Media Coverage

In this paper, an SIRS epidemiological model with nonlinear incidence rate incorporating media coverage is investigated and the threshold of the existence of various equilibria are found. By means of constructing Dulac function and combing with the local stability of the corresponding linear system, one can verify that the disease-free equilibrium is globally asymptotically stable if the reproduction number R0 is less than unity, and the endemic equilibrium is globally asymptotically when it exists. From the analysis and simulation, we can find that though the media coverage is not a determined fact to eradicate the infection of the diseases, to a certain extent, the effective media coverage can postpone the arrival of the infection peak, and a fewer number of individuals become infected in the course of transmission.
Development and Standardization of a Semantic Comprehension Assessment Tool for Dementia in Bengali

Dementia is a neuro-communication disorder characterized by an impairment of the semantic memory responsible for processing meaning-related knowledge. The effect of dementia on semantic comprehension skill varies based on severity of dementia. In the same context, semantic memory has been described as the form of memory that allows humans to understand the meanings of words, objects, and events; to name and to produce meaningful statements; and to behave in a manner that reflects knowledge about the objects and events that exist in the environment. No standardized test has been documented till date for measuring semantic comprehension in dementia patients in Indian languages. With Bengali being the second widely spoken language in India (Census, 2001), the development and standardization of semantic comprehension test in Bengali was envised. The present study aimed to develop and standardize semantic comprehension test in Bengali and to assess the extent of semantic comprehension deficit across mild, moderate and severe dementia subjects categorized through dementia severity rating scale in Bengali using the developed test. A total of sixty participants (30 dementia patients and 30 normal subjects) participated in the study. The clinical population consisted of 10 mild, 10 moderate and 10 severe degree dementia patients identified with the help of clinical dementia rating scale. The developed semantic comprehension test comprised of seven sections representing noun, polar questions, semantic anomaly, syntagmatic relations, paradigmatic relations, semantic contiguity, and semantic similarity. Noun section of the semantic protocol was categorized into five sub-sections like body parts, common objects, colours, geometric forms, and numbers. Stimulus was given through auditory, picture and orthographic mode. Responses were analyzed and a score of ‘2’/ ‘1’/ ‘0’ were given for every correct response without prompt, with prompt, and incorrect/no response even after prompt responses respectively. Results indicated significant difference between the scores obtained by mild, moderate and severe dementia patients on semantic comprehension test. The mild dementia patients performed better than moderate and severe dementia patients in the semantic comprehension test. Results also indicated the developed semantic comprehension test to be valid and to be a reliable tool for assessment of semantic comprehension deficits across different degrees of dementia. The semantic comprehension test was thus validated to be an efficient, reliable and valid tool to be used with native Bengali speakers for evaluating semantic comprehension skills among individuals with neuro-communication disorders.
A Keyquery-Based Classification System for CORE

We apply keyquery-based taxonomy composition to compute a classification system for the CORE dataset, a shared crawl of about 850,000 scientific papers. Keyquery-based taxonomy composition can be understood as a two-phase hierarchical document clustering technique that utilizes search queries as cluster labels: In a first phase, the document collection is indexed by a reference search engine, and the documents are tagged with the search queries they are relevant�for their so-called keyqueries. In a second phase, a hierarchical clustering is formed from the keyqueries within an iterative process. We use the explicit topic model ESA as document retrieval model in order to index the CORE dataset in the reference search engine. Under the ESA retrieval model, documents are represented as vectors of similarities to Wikipedia articles; a methodology proven to be advantageous for text categorization tasks. Our paper presents the generated taxonomy and reports on quantitative properties such as document coverage and processing requirements.
Humanoid Robot: A Review of the Architecture, Applications and Future Trend

With the advancement in the area of robotics, exoskeleton technology has come a long way since its beginnings in the late 60's. Researchers over the world have developed their own exoskeleton prototypes and some of the well known exoskeleton includes the BLEEX, MIT exoskeleton, HAL, LOPES, ALEX and many more. Although technologies have since improved from the 60's, challenges still exist in exoskeleton design. In this study, we are going to review different exoskeleton technologies as well as its role in the area of rehabilitation. This purpose in rehabilitation is promising, based on countless of researches which have been done.
Measuring the Relationship between Individual and Contextual Variables with Technology Implementation: Analyses of Year Three - IMPACT Project

SHATTUCK, DOMINICK C. Measuring the Relationship between Individual and Contextual Variables with Technology Implementation: Analyses of Year Three IMPACT Project. (Under the direction of Denis Gray, Committee Chairperson; Jason Osborne, Jason Allaire and Roger Mitchell.) The field of educational technology is continually looking to more precisely understand the relationship between leadership, technology-related beliefs, technology resources, supportive environment and technology implementation in classrooms. Previous research has identified relationships between these factors. However, the types of predictors examined, the quality of the dependent variables used and the sophistication of the statistical tools used have sometimes been lacking. This research evaluated these factors within the context of the IMPACT project a three-year technology-enrichment intervention. Utilizing the last year of the data from this project, this cross-sectional study used structural equation modeling (SEM) to investigate the causal relationship between leadership, beliefs, technology resources, supportive environment and technology implementation, which is divided into planning, instruction and student use in classrooms. Differentiating technology implementation is an important contribution of this research as previous studies focused on a particular technology and a specific type of application. We found that teachers’ beliefs about technology had the strongest positive relationship with technology implementation. Leadership was found to indirectly influence technology implementation through teachers’ their beliefs about technology. When developing technology based interventions, policy makers should include evidence of the technology’s effectiveness to influence teachers’ beliefs about that technology. This study provides a unique look at technology implementation using a large scale intervention with a comparison group and differentiated forms of technology implementation.

Systems biology Inference of gene regulatory networks and compound mode of action from time course gene expression profiles

Motivation: Time series expression experiments are an increasingly popular method for studying a wide range of biological systems. Here wedevelopedanalgorithmthatcan infer the localnetworkofgene–gene interactions surrounding a gene of interest. This is achieved by a perturbation of the gene of interest and subsequently measuring the gene expression profiles at multiple time points. We applied this algorithm to computer simulated data and to experimental data on a nine gene network in Escherichia coli. Results: In this paper we show that it is possible to recover the gene regulatory network from a time series data of gene expression following a perturbation to the cell. We show this both on simulated data and on a nine gene subnetwork part of theDNA-damage response pathway (SOS pathway) in the bacteria E. coli.

We Want an Education in a Safe School: Students Demand Institutional Accountability for Anti-Asian Violence at South Philadelphia High School

On December 3, 2009, dozens of Asian immigrant students at South Philadelphia High School (SPHS) in Philadelphia, Pennsylvania, were targeted and assaulted by their non-Asian peers throughout the school day. Sadly, this horrific event was simply another addition to the ongoing and pervasive anti-Asian and anti-immigrant violence at the school. Despite students' and community advocates' previous efforts to address bias-based harassment for over a year, in the days following the attacks, school and district officials endeavored to downplay the severity of these assaults and refused to acknowledge that the attacks were racially motivated. In the face of indifference by these officials, Asian immigrant students from the school, with the support of community advocates, began a campaign against the ongoing violence.
Generalised Reciprocity and Reputation in the Theory of Cooperation: A Framework

Abstract We study the Iterated Bilateral Reciprocity game in which the need for help arises randomly. Players are heterogeneous with respect to ‘neediness’ i.e. probability of needing help. We find bounds on the amount of heterogeneity which can be tolerated for cooperation (all players help when asked to help) to be sustainable in a collectivity. We introduce the notion of Generalised Reciprocity. Individuals make a costly first move to benefit another under the reasonable expectation that either the other or somebody else will reciprocate. We hope that these tentative attempts at extending Axelrod’s seminal work on cooperation will inspire future efforts in the field of organisational culture and social theory more generally.
Interest Rate Pass-Through in Romania and Other Central European Economies

Interest rate pass-through from policy interest rates to market rates and inflation has been hypothesized to play a lesser role in Romania than in other Central European transition economies. This paper tests this hypothesis and concludes that it cannot be supported by the data. Hence pass-through in Romania is concluded to be in line with that in comparable economies in the region. Moreover, the interest rate pass-through has become more pronounced over time.
Mobile robot design in education

This paper describes the course on robot design that electronics systems engineers take in their last semester at the Instituto Tecnologico de Estudios Superiores de Monterrey (ITESM) in Mexico. In this course, the use of project oriented learning (POL) and collaborative learning are proposed. The paper also describes the design and implementation of a modular, low-cost, three-wheeled autonomous robotic platform, to serve as a base platform from which different applications, educational and research, could be mounted.
Sequential Implementation of Parallel Narrowing

Parallel narrowing has been proposed by Antoy, Echahed and Hanus. They generalize to narrowing the notion of necessary set of redexes introduced by Sekar and Ramakrishnan. We present a high-level implementation by transforming weakly orthogonal, constructor-based programs into Prolog with the help of parallel deenitional trees. For strategies based on parallel rewriting, this is particularly diicult, because we have to take into consideration the whole term. A better strategy is obtained by combining parallel narrowing with simpliication, exploiting both determinism and expression parallelism. We point out the advantages of the new strategy by comparative measurements.
The Relationship Between Blood Lead, Bone Lead and Child Intelligence

We report associations between serial measures of blood lead and intelligence in children age 10–12 years, half heavily exposed to lead from the prenatal period onward, and half relatively unexposed. For a subsample, we examine bone lead-IQ associations, comparing them with blood lead associations. Both blood and bone lead levels were associated with intelligence decrements, small relative to the contribution of social factors. For each doubling of Tib-Pb, Full Scale, Performance, and Verbal IQ decreased by an estimated 5.5, 6.2, and 4.1 points, respectively. Bone lead-IQ associations were stronger than those for blood lead, which nonetheless provide robust analogues. Current BPb, easy to obtain, provides a useful means for assessing Pb exposure/IQ associations.
