Developing Engaged Scholars: The Graduate Advisor-Advisee Relationship

A critical dimension in the development of emerging engaged scholars is the advisor-advisee relationship. A multiyear, multiuniversity study of doctoral students interested in community-engaged scholarship and their advisors found that advisors influenced their advisees’ specific approach to community engagement; advisees built extensively on their own community-based experiences and even pushed their advisors in co-learning about communityengaged scholarship; and advisors and advisees shared recognition of lack of support for community engagement but pursued it anyway. Faculty as Engaged Scholars Scholars are being called to reframe their conventional understanding of teaching, research, and service in the academy in a “scholarship of engagement” that builds on ideas formulated by Ernest Boyer (1990, 1996). The Carnegie Foundation for the Advancement of Teaching (2008) defines community engagement as “collaboration between institutions of higher education and their larger communities . for the mutually beneficial exchange of knowledge and resources in a context of partnership and reciprocity. ” Engaged scholarship is often represented by work done within Stokes’s (1997) “Pasteur’s Quadrant”: that is, doing use-inspired research, building on basic research while improving practice. Although the philosophical, theoretical, and practical dimensions of this movement seem consistent with a social justice mission, many disciplines have contributed little to the theory and practice of scholarly engagement. This lack of involvement in the face of increasing recognition and legitimacy for community-engaged learning in higher education indicates the need for a cadre of faculty members with the knowledge and skills required to participate in engaged scholarship. In this context, there is increasing recognition of the importance of future faculty: graduate students (Applegate, 2002; Bloomfield, 2006; O’Meara & Jaeger, 2007), who are being socialized to the academic career (Austin, 2002). However, established professional development mechanisms or pathways are lacking for graduate students and faculty members who seek community-engaged careers in the academy. Further, faculty members who are not themselves community-engaged often misunderstand or misrepresent community-engaged scholarship. This can dissuade graduate students and other faculty from seriously considering community-engaged academic careers. Thus we focused on this period when graduate students are learning what society expects of faculty and how to apply their research to society. We examined how they become educated as community-engaged scholars and what factors could provide insight for faculty to recognize the importance and implement the practice of community-engaged scholarship.
Full Wave Analysis of RF Signal Attenuation in a Lossy Rough Surface Cave Using a High Order Time Domain Vector Finite Element Method

We present a computational study of signal propagation and attenuation of a 200 MHz planar loop antenna in a cave environment. The cave is modeled as a cylindrical guiding structure with a lossy wall. The wall is nominally circular with a random roughness. To simulate a broad frequency band, the full wave Maxwell equations are solved directly in the time domain via a high order vector finite element discretization using the massively parallel CEM code EMSolve. The numerical technique is first verified against theoretical results for a planar loop antenna in a smooth lossy cave. The simulation is then performed for a series of random rough surface meshes in order to generate statistical data for the propagation and attenuation properties of the antenna in a cave environment. Results for the mean and variance of the power spectral density of the electric field are presented and discussed.
Sampling Similarity in Image and Language - Figure and Ground in the Analysis of Filmic Audio Description

Audio description can be defined as intermodal translation in which the visual representation (for example, of a film) is verbalised and spoken in order to facilitate and enhance reception by visually impaired audiences. By its very essence, audio description requires analysing the relation of language to non-linguistic, visual representation. The theory of Figure and Ground segregation has been developed for both visual perception and language to explain how we perceive “thing-like” figures and “substance-like” grounds in space. This segregation is reflected in language by coding certain elements as figures in reference to a more (static) ground. This paper addresses the Figure and Ground theory both in visual representation and in its linguistic translation. On the basis of theory-led sample analyses on a contemporary film and its different-language audio descriptions, this study presents evidence that the verbal representation can parallel the visual segregation of Figure and Ground. Furthermore, it discusses the application of the theoretical Figure and Ground characteristics and suggests some clarification to them.
Impacts of macroalgal competition and parrotfish predation on the growth of a common bioeroding sponge

Clionaids, an abundant group of bioeroding sponges, are important competitors of corals, but their interactions with other major taxa are poorly understood. This study examined the relative effect of predation and macroalgal competition on the growth of Cliona tenuis at Glover's Reef Atoll, Belize. A field experiment was designed to isolate the importance of each factor and its interactions, by means of exclusion cages to assess the effects of fish predators, and algal trans- plantation to assess the effects of macroalgal competition (Lobophora variegata), over 286 d. To obtain complementary data on the net outcome of predation and competition in situ, predation intensity and the competitive effects on C. tenuis of 5 different competitors were monitored in the field. Competition with macroalgae significantly reduced the size of the sponge by 38 ± 11% (SE). Despite a high predation rate (1 bite 100 cm �2 h �1 ), no effect of the interaction of predation with macroalgal competition was detected. The in situ observations found that L. variegata was the strongest competitor limiting the growth of C. tenuis. Overgrowth of corals by clionaids and macroalgae continues to be a matter of concern, but our results suggest that the antagonistic competition between sponges and algae might weaken their potential combined effect on corals.
Molecular Characterization and Phylogenetic Analysis of Diphyes dispar (Siphonophora: Diphyidae) from the Laccadive Sea, off the south-west coast of Arabian Sea, Indian Ocean

Diphyes dispar is a hydroid in the family Diphyidae. Ecologically, they are insatiable predators of zooplankton and can have significant effects on marine ecosystem formation and functioning. Using morphological characters to accurately assign this species based on taxonomy would require comprehensive anatomical studies. Molecular characterization using DNA barcodes are useful to discover new species, reveal cryptic species and assess taxonomically-significant variation within species with broad or disjunct distributions. In this study, a portion of the mitochondrial Cytochrome Oxidase I (mtCOI) gene obtained from D. dispar was used as DNA barcode for molecular taxonomy. Kimura-2Parameter (K2P) genetic distance between sequence variants within the dispar species ranged from 0 to 0.058 (mean 0.033). K2P genetic distances were significantly lower between individuals of the same species than between individuals of different species within the genus, Diphyes (mean 0.133; S.D.0.011). A phylogenetic tree generated by Neighbor Joining (NJ) using K2P distances reliably clustered all barcodes of the same species with 100% bootstrap support, ensuring accurate identification of species. Intraand inter-specific variation of the mtCOI gene is appropriate to be used as a DNA barcode for species-level identification and phylogenetic analysis. This is the first study conducted to characterize D.dispar from the Laccadive Sea, off the south-west coast of Arabian Sea in the Indian Ocean using the sequence analysis of mtCOI. This study provides a set of molecular tools that can be used to address questions of speciation, biodiversity, and population boundaries. In light of the crucial position of zooplankton in ocean food webs, their usefulness as rapid responders to environmental alteration, and the increasing scarcity of taxonomists, the use of DNA barcodes is an important and useful approach for rapid analysis of species diversity and distribution.
Sampling People or People in Places? The BES as an Election Study

Electoral surveys conducted as part of the regular series of British Election Studies have used a stratified, clustered sampling design. This is constructed to ensure a nationally representative sample of voters (after weighting) but does not necessarily ensure a representative sample of the different social areas within the country. Much recent work has indicated the important role of local social and electoral milieux in the structuring of electoral behaviour but these are not reflected in the sampling design. An analysis of the geography of the face-to-face pre-election component of the 2005 BES shows not only that it was unrepresentative of certain types of area (defined using bespoke neighbourhood data) but also that it was less representative of such areas than the two (larger) internet samples (pre- and post-election) also undertaken as part of the 2005 BES. This suggests the need to reconsider the nature of the sample designs (even the entire survey methodology) to be deployed at future election studies in Great Britain.
Study of flow stress and spall strength of additively manufactured Ti-6-4 alloy

The use of additive manufacturing (AM) by Electron Beam Melting (EBM) or Selective Laser Melting (SLM) has extensively grown in the past few years. A major goal in AM is to manufacture materials with mechanical properties at least as good as traditionally manufactured materials. In this work we present the results of planar impact tests and Split Hopkinson Pressure Bar tests (SHPB) on Ti-6Al-4V manufactured by EBM and LSM techniques. Stress strain curves based on SHPB measurements at strain rate of about 1500 s-1 display similar plastic flow stresses for SLM and EBM processed Ti-6Al-4V alloys, and about 15% higher than reported for commercial Ti-6Al-4V alloy. Results of planar impact tests on SLM samples display slightly higher spall strength than EBM while the stress at Hugoniot elastic limit (HEL) is practically the same. Hugoniot elastic limit and spall strength estimates for EBM-and SLM-processed Ti-6Al-4V alloys are at least as high as values obtained for conventionally-processed alloys. The results of post mortem SEM analysis of the spall fracture have demonstrated significant differences in the spall fracture characteristics between the AM-processed and commercial Ti-6Al-4V alloys.
Nanomechanical switches based on metal-insulator-metal capacitors from a standard complementary-metal-oxide semiconductor technology

We report experimental demonstrations of contact-mode nano-electromechanical switches obtained using a capacitor module based on metal-insulator-metal configuration of a standard commercial complementary metal oxide semiconductor technology. The developed 2 terminals Titanium Nitride switches operate at low voltages (∼10 V) thanks to its small gap (27 nm), showing an excellent ION/IOFF ratio (104) and abrupt behavior (5 mV/decade, one decade of current change is achieved with a 5 mV voltage variation). A switch configuration is also presented where using two electrodes three different contact mode states can be obtained, adding functionalities to mechanical switches configurations.
Residual based a posteriori error estimators for eddy current computation

We consider H (curl ;Ω)-elliptic problems that have been discretized by means of Nedelec's edge elements on tetrahedral meshes. Such problems occur in the numerical computation of eddy currents. From the defect equation we derive localized expressions that can be used as a posteriori error estimators to control adaptive refinement. Under certain assumptions on material parameters and computational domains, we derive local lower bounds and a global upper bound for the total error measured in the energy norm. The fundamental tool in the numerical analysis is a Helmholtz-type decomposition of the error into an irrotational part and a weakly solenoidal part.
SUBTLE METHODS IN C

Nowadays complex software systems are designed and implemented with the help of the object-oriented paradigm principally. However, object-oriented languages support the object-oriented paradigm in different ways with different constructs. C++ has a sophisticated inheritence notation based on access modifiers. C++ distinguishes virtual, pure virtual and non-virtual methods. Java uses final classes and methods to disable inheritance. However, Java does not support multiple inheritance. Eiffel allows renaming inherited methods. In this paper we present some method utilites for C++ to create safer and more flexible object-oriented systems. We present how the method renaming can be implemented. We developed constructs to create final and unhidable methods. These constructs are implemented with the help of C++ template facilities. We present scenarios where one can write safer code with our constructs.

Genetic Variability of Service Tree (Sorbus domestica L.) in the Hungarian Middle Mountains : Based on cpDNA Analysis in Two Regions

A genetic inventory was conducted at maternally inherited chloroplast DNA (cpDNA) gene loci of 196 adult service trees (S. domestica). The sampled trees represent autochthonous collectives/populations originating from 2 distant regions, from contrasting habitats, a forested area (eastern part of the Dunazug Mountains) and cultured habitats (Zemplén Mountains), respectively. Strong intrapopulation variation was observed; percentages of molecular variance were: between regions 27%, among populations/regions 6%, within populations 67%. Considering all samples, the major part of total diversity (ht = 0.752) was contributed by intrapopulation diversity (hs = 0.583). Species diversity was represented differently in individual populations. E.g. the population Kácsárd contains only one haplotype: the doubtless sign of local human cultivation. The population Buda Hills has an average differentiation considering the whole sampled material but the highest when evaluating the region north from Budapest separately. That points to the dispersion after an introduction event, probably parallel to adaptive radiation under selection influence. In the study genetically polymorphic populations containing unique haplotypes were detected, providing important information for forest management, gene conservation and nature protection activities. The described work is part of ex situ gene conservation projects of the species in Hungary.
'Dependent Contractors' in the Gig Economy: A Comparative Approach

In response to worker misclassification lawsuits in the United States, there have been recent calls for the creation of a hybrid category in between employee and independent contractor specifically for the gig economy. However, such an intermediate category is not new. In fact, the intermediate category has existed in many countries for decades, producing successful results in some, and misadventure in others. In this article, we use a comparative approach to analyze the experiences of Canada, Italy, and Spain with the intermediate category. In our analysis we focus on a set of questions: Is labour law fundamentally outdated for the digital age? Does the gig economy need its own specialized set of rules, and what should they look like? What role does digitalization and technology play in the casualization of work? We ultimately conclude that workable proposals for a third category must also encompass other forms of precarious employment.
Study on the evaluation of serum hsCRP as predictor of the coronary artery disease by using Framingham Risk Score (FRS)

Summary The study about the relationship between serum hsCRP value and the cardiovascular disease has been few in Japan and its relationship is uncertain yet. The aim of the study is to clarify the relationship between serum hsCRP value and Framingham Risk Score (FRS) as a forecast score of the coronary artery disease by using basics medical checkup data. We divided a subject into following five groups according to serum hsCRP: ''Low'' as 0.01-0.06 mg/dl, ''Mild'' as 0.07-0.11 mg/dl, ''Moderate'' as 0.12-0.19 mg/dl, ''High'' as 0.20-0.38 mg/dl, ''Highest'' as 0.38-1.50 mg/dl. Results as follows: As the relationship between serum hsCRP and FRS, higher group of serum hsCRP value showed higher FRS, and ''Low'' and ''Mild'' group were significance differences with other three groups. Groups of serum hsCRP 0.12 mg/dl over showed high risk of the coronary artery disease as FRS≧6 by logistic-regression analysis. The result of present study suggested that serum hsCRP value was associated with a risk factor of the coronary artery disease for men and women. Serum hsCRP value showed a relationship with the FRS as well as a coronary artery disease-related factor. As known the inflammation is a new risk factor of the coronary artery disease, serum hsCRP value could be a representative test value to show episode risk of the coronary artery disease.
ASSESSING VALIDITY AND RELIABILITY OF SOCIAL MEDIA AS AN EMPOWERMENT TOOL FOR A GROUP AT RISK IN MALAYSIA

This article discusses a study on empowerment of a group at risk via social media in Malaysia which focuses on five important dimensions namely economy, social and cultural, legal, political, and psychology. The group at risk focused in the study refers to women. The study employed a survey that uses a set of online questionnaire distributed to women who are actively using social media, particularly social networking sites. This study involves a sample of 1,307 respondents in an exploratory study, in which a 5-factor 24-item instrument to measure empowerment comprising of the five hypothesised dimensions were being developed. Results confirm factor structures of the empowerment model and suggest a more parsimonious instrument for each; a 5-factor 15-item scale for social media empowerment, as compared to the result of pilot study conducted. Goodness-of-fit indices for the model are presented. The result shows that the five dimensions are significant to the empowerment model of women in Malaysia. The findings can contribute greatly to a better understanding of the empowerment mechanism behind social media issues pertaining to women.
An Agent-based CBIR System for Medical Images

The growing number of image acquisition and storage systems in the digital world demand for the new retrieval methods. Most of the existing retrieval methods use textual information, which has been mainly entered manually for every image in the image collection. In order to access the images of interest, user gives textual input against which images are retrieved from the image collection. Sometimes, this results in garbage retrieval due the human involvement in the image annotation process. So more efficient image retrieval mechanism is needed. To overcome the issue, other approach which is generally considered is content-based image retrieval (CBIR). CBIR depends on the automatically extracted features for every image in the image collection as well as their storage and comparison upon a query. Therefore, feature extraction technique and their storage space are important aspects of CBIR. In this paper, we design and develop agent-based CBIR system for image retrieval and suggest the best feature extraction technique in terms of less storage space and more accurate search results. Although the proposed image retrieval technique can be used for any type image collection, our work focuses on the medical images.
New Software Generation for Greener Energy Efficient Mechatronic System Design & Analysis

In the world of simulation software, many different approaches are used to obtain accurate hydraulic circuit simulation. Most of these tools model components as a set of mathematical equations parameterized with mechanical and geometric data for each component. They are able to simulate in depth specific functions of a circuit, however it becomes progressively a more demanding task to simulate more complex and complete systems. One of the key elements of simulation software is its ability to model valve performance in terms of flow characteristics, pressure drop and flow force. This also holds true for pumps and motors where the knowledge of efficiencies is required to achieve realistic duty cycle behavior. In this paper, the chosen approach is to demonstrate the efficiency of modeling components using a software downstream design methodology by implementing readily available performance curves and other characteristics of hydraulic components and functions. This downstream method of modeling components ensures the reliability and accuracy of systems behavior based on manufacturer specific data and allows for fast simulation of complete virtual machines which is impractical to achieve by traditional upstream programming. The simulation of a complete hydraulic system delivers global validation and analysis capabilities that can also be exploited beyond the engineering design scope including maintenance diagnostics and training activities. This paper will demonstrate that using Automation Studio™ ? a commercially available off-the-shelf drawing and simulation software tool that uses mainly downstream design? simulation data and OEM product information can be easily entered from a readily available hydraulic component vendor in order to create valves, pumps and motors for fast and accurate sizing and system simulation of a virtual machine. The ability to realistically simulate entire machines offers a unique capability to monitor, and study specific performance criteria such as: hysteresis, pressure drop, leakage, flow force, and other flow/pressure characteristics, power generation and transmission up to the full energy consumption at various operating conditions.
