Examining Scholar-Practitioner Identity in Peer-Led Research Communities in Higher Education Programs
Authors: M. Bettencourt Genia , K. Malaney Victoria , J. Kidder Caitlin , A. George Mwangi Chrystal 
Published: October 2017

Aim/Purpose: The purpose of this study is to explore how research skills and communities can be promoted in student affairs and/or higher education graduate preparation programs through a peer-led, team-based model.

Background: Numerous scholars emphasized a lack of empirical research being conducted by student affairs professionals, even though integration of scholarship with practice remains of critical importance to field of higher education.

Methodology: Though a descriptive case study of a graduate research course, we engage both quantitative and qualitative data points in a convergent parallel mixed methods design.

Contribution: This study provides an important contribution in understanding how graduate programs may better prepare students to engage within a spectrum of scholar-practitioner identity.

Findings: Findings suggest that while participants see value in a scholar-practitioner identity and its impact on their future goals, there is often a discrepancy between the perceived feasibility of embodying the role in actual student affairs practice as well as variations across master’s and doctoral student levels.

Recommendations for Practitioners: Recommendations for practice include working to integrate scholarship in professional positions and promoting greater collaboration between graduate coursework and professional supervisors.

Recommendation for Researchers:	Recommendations for researchers include continuing to examine how communities of practice develop across the levels of graduate socialization.

Impact on Society: Understanding how individuals engage in scholarship in their fields carries interdisciplinary implications for merging research into professional roles.

Future Research: A key area for future research is longitudinal inquiry into how emerging professionals in higher education/student affairs negotiate the scholar-practitioner spectrum across career development.
Typology on Leadership toward Creativity in Virtual Work
Authors: A Humala Iris 
Published: October 2017

Aim/Purpose: This study aims to develop a descriptive typology to better identify leadership toward creativity in virtual work in different types of companies.

Background:	The study empirically explores how leadership toward creativity occurs in virtual work and uses the theoretical lenses of creativity-conducive leadership and heterarchy to generate a typology.

Methodology	: A multiple qualitative case study design, interpretivist approach, and abductive analysis are applied. Data is collected by interviewing 21 leaders and employees face-to-face in four companies in the ICT sector and one business advisor company.

Contribution: The empirical evidence of this study enriches the understanding of leadership toward creativity in virtual work and contributes to the limited empirical knowledge on leadership that stimulates a virtual workforce to achieve creativity.

Findings: The four different types of companies in the typology utilize various transitions toward leadership creativity in virtual work. The trend in leadership in the existing virtually networked business environment is toward the “collective mind” company, which is characterized by shared values, meaningful work, collective intelligence, conscious reflection, transparency, coaching, empowering leadership by example, effective multichannel interaction, and assertiveness. The findings empirically support applying a heterarchy perspective to lead a virtual workforce toward creativity and promote leaders who are genuinely interested in people, their development, collaboration, and technology.

Recommendations for Practitioners: The typology helps professionals realize the need to develop leadership, communication, interaction, learning, and growth to foster creative interaction and improve productivity and competitiveness.

Recommendation for Researchers:	This study enables researchers to more rigorously and creatively conceptualize the conditions and relationships in leadership that facilitate creativity in virtual work.

Impact on Society	: The findings highlight humanistic values for developing leadership. The study strengthens the view that collective creativity in virtual work cannot emerge without virtual and physical interaction in appropriate spaces and caring for each other.

Future Research: Future studies may focus on other fields, industries, networks, roles of materialities, and employees in fostering creativity and on theory development. Longitudinal studies are advisable.
Broad Susceptibility of Nucleolar Proteins and Autoantigens to Complement C1 Protease Degradation

Published: October 2017

Abstract
Anti-nuclear autoantibodies, which frequently target the nucleoli, are pathogenic hallmarks of systemic lupus erythematosus (SLE). Although the causes of these Abs remain broad and ill-defined, a genetic deficiency in C1 complex (C1qC1r2C1s2) or C4 is able to induce these Abs. Considering a recent finding that, in dead cells, nucleoli were targeted by C1q and two nucleolar autoantigens were degraded by C1r/C1s proteases, we considered that C1 could help protect against antinuclear autoimmunity by broadly degrading nucleolar proteins or autoantigens. Nucleoli were isolated to homogeneity and structurally defined. After C1 treatment, cleaved nucleolar proteins were identified by proteomic two-dimensional fluorescence difference gel electrophoresis and mass spectrometry, and further verified by Western blotting using specific Abs. The extent of nucleolar autoantigen degradation upon C1 treatment was estimated using SLE patient autoantibodies. The isolated nucleoli were broadly reactive with SLE patient autoantibodies. These nucleoli lacked significant autoproteolysis, but many nucleolar proteins and autoantigens were degraded by C1 proteases; &gt;20 nucleolar proteins were identified as C1 cleavable. These were further validated by Western blotting using specific Abs. The broad autoantigenicity of the nucleoli may attribute to their poor autoproteolysis, causing autologous immune stimulation upon necrotic exposure. However, C1q targets at these nucleoli to cause C1 protease activation and the cleavage of many nucleolar proteins or autoantigens. This may represent one important surveillance mechanism against antinuclear autoimmunity because C1 genetic deficiency causes anti-nuclear autoantibodies and SLE disease.

Abstract
Several complement proteins exacerbate prion disease, including C3, C1q, and CD21/35. These proteins of the complement cascade likely increase uptake, trafficking, and retention of prions in the lymphoreticular system, hallmark sites of early prion propagation. Complement regulatory protein factor H (fH) binds modified host proteins and lipids to prevent C3b deposition and, thus, autoimmune cell lysis. Previous reports show that fH binds various conformations of the cellular prion protein, leading us to question the role of fH in prion disease. In this article, we report that transgenic mice lacking Cfh alleles exhibit delayed peripheral prion accumulation, replication, and pathogenesis and onset of terminal disease in a gene-dose manner. We also report a biophysical interaction between purified fH and prion rods enriched from prion-diseased brain. fH also influences prion deposition in brains of infected mice. We conclude from these data and previous findings that the interplay between complement and prions likely involves a complex balance of prion sequestration and destruction via local tissue macrophages, prion trafficking by B and dendritic cells within the lymphoreticular system, intranodal prion replication by B and follicular dendritic cells, and potential prion strain selection by CD21/35 and fH. These findings reveal a novel role for complement-regulatory proteins in prion disease.

Published: October 2017

Little is known about men with prostate cancer who decline conventional treatment and use only complementary and alternative medicine (CAM). Objectives To 1) explore why men decline conventional prostate cancer treatment and use CAM 2) understand the role of holistic healing in their care, and 3) document their recommendations for health care providers. Methods Semi-structured interviews and follow-up focus groups. Sample Twenty-nine men diagnosed with prostate cancer who declined all recommended conventional treatments and used CAM. Results Based on strong beliefs about healing, study participants took control by researching the risks of delaying or declining conventional treatment while using CAM as a first option. Most perceived conventional treatment to have a negative impact on quality of life. Participants sought healing in a broader mind, body, spirit context, developing individualized CAM approaches consistent with their beliefs about the causes of cancer. Most made significant lifestyle changes to improve their health. Spirituality was central to healing for one-third of the sample. Participants recommended a larger role for integrated cancer care. Conclusion Men who decline conventional prostate cancer treatment and use CAM only may benefit from a whole person approach to care where physicians support them to play an active role in healing while carefully monitoring their disease status.

Abstract. Globally, the waste sector contributes to nearly a fifth of anthropogenic methane emitted to the atmosphere and is the second largest source of methane in the UK. In recent years great improvements to reduce those emissions have been achieved by the installation of methane recovery systems at landfill sites, and subsequently methane emissions reported in national emission inventories have been reduced. Nevertheless, methane emissions of landfills remain uncertain and quantification of emission fluxes is essential to verify reported emission inventories and to monitor changes in emissions. Here we present a new approach for methane emission quantification from a complex source such as a landfill site by applying a computational fluid dynamics (CFD) model to calibrated in situ measurements of methane as part of a field campaign at a landfill site near Ipswich, UK, in August 2014. The methane distribution for different meteorological scenarios is calculated with the CFD model and compared to methane mole fractions measured by an in situ Fourier-transform infrared (FTIR) spectrometer downwind of the prevailing wind direction. Assuming emissions only from the active site, a mean daytime flux of 0.83 mg m−2 s−1, corresponding to a spatially integrated emission of 53.3 kg h−1, was estimated. The addition of a secondary source area adjacent to the active site, where some methane hotspots were observed, improved the agreement between the simulated and measured methane distribution. As a result, the flux from the active site was reduced slightly to 0.71 mg m−2 s−1 (45.6 kg h−1), and at the same time an additional flux of 0.32 mg m−2 s−1 (30.4 kg h−1) was found from the secondary source area. This highlights the capability of our method to distinguish between different emission areas of the landfill site, which can provide more detailed information about emission source apportionment compared to other methods deriving bulk emissions.

Published: October 2017

Abstract. In this paper we discuss the results of an intercomparison for electric field strength measurements within the German Calibration Service (Deutscher Kalibrierdienst – DKD). The comparison has been carried out on the field strength value required to reach a display reading of 20 V m−1 of the field probes for frequencies between 100 MHz and 18 GHz. Five laboratories joined the intercomparison including the Physikalisch-Technische Bundesanstalt (PTB), the German National Metrology Institute that keeps the primary standard for electric field strength. As measurement artefacts both a small 1-axis probe usually used as transfer sensor at PTB and a larger 3-axis commercial field probe have been used. While the results agree well for the small field probe and when the larger commercial 3-axis field probe is oriented in the direction of the magnetic field, larger deviations occur, when the larger 3-axis field probe is oriented into the direction of the Poynting vector of the calibration field.
Quando os laços de amizade e solidariedade são rompidos: questões de disputa e medição de terras e posse de animais
Authors: Von Mühlen Caroline 
Published: October 2017

Este artigo analisa alguns confrontos cotidianos e episódios conflituosos ocasionados por questões econômicas envolvendo alemães, seus descendentes e nacionais em São Leopoldo, entre 1846 e 1871. Ao analisar e quantificar os dados de processos criminais, constatou-se
que os agentes históricos faziam uso da violência em situações de disputas de terras, problemas decorrentes de medições e invasões de propriedades. Os desentendimentos e os conflitos ocorreram, sobretudo, entre vizinhos, amigos e conhecidos. Assim, as relações sociais, por um lado, podiam ser permeadas por redes de amizade, solidariedade e reciprocidade,
mas, por outro, podiam ser rompidas, gerando inimizades, rixas e
conflitos. Busca-se, neste texto, atentar para os comportamentos dos indivíduos envolvidos nas querelas, as motivações para as disputas e o contexto histórico dos atores sociais.

Authors: Voos Ivani Cristina , Ferreira Gabriela Kaiana 
Published: October 2017

Este artigo tem como objetivo realizar uma breve análise dos Objetos Educacionais Digitais (OED) disponíveis nas coleções didáticas da componente curricular Física selecionadas no Programa Nacional do Livro Didático (PNLD/2015) a fim de averiguar se os mesmos apresentam recursos de acessibilidade para estudantes com deficiência visual. Foram analisadas as quatro coleções de Física que disponibilizaram o recurso digital como parte integrante da obra. Discutir a acessibilidade disponibilizada nos recursos digitais se faz necessária visto o crescente número de estudantes com deficiência visual no ensino regular. Após as análises concluiu-se preliminarmente que nenhuma das quatro coleções apresenta acessibilidade para os recursos, fato esse que pode ser negativo para o processo educativo de estudantes cegos e baixa visão que farão uso dos OED.
GrowYourIC: A Step Toward a Coherent Model of the Earth's Inner Core Seismic Structure
Authors: Lasbleis Marine , Waszek Lauren , Day Elizabeth A. 
Published: October 2017

AbstractA complex inner core structure has been well established from seismic studies, showing radial and lateral heterogeneities at various length scales. Yet no geodynamic model is able to explain all the features observed. One of the main limits for this is the lack of tools to compare seismic observations and numerical models successfully. We use here a new Python tool called GrowYourIC to compare models of inner core structure. We calculate properties of geodynamic models of the inner core along seismic raypaths, for random or user‐specified data sets. We test kinematic models which simulate fast lateral translation, superrotation, and differential growth. We explore first the influence on a real inner core data set, which has a sparse coverage of the inner core boundary. Such a data set is however able to successfully constrain the hemispherical boundaries due to a good sampling of latitudes. Combining translation and rotation could explain some of the features of the boundaries separating the inner core hemispheres. The depth shift of the boundaries, observed by some authors, seems unlikely to be modeled by a fast translation but could be produced by slow translation associated with superrotation.
Hollow Mesoporous Functional Hybrid Materials: Fascinating Platforms for Advanced Applications
Authors: Park Sung Soo , Ha Chang‐Sik 
Published: October 2017

AbstractFunctionalized hollow nano‐ and microspheres containing both hollow and mesoporous structures are fascinating materials for a broad range of applications, such as nanoparticle collectors, catalysis, drug delivery systems, immobilization of biomolecules, and the adsorption and separation of gas and pollutants, because of their empty interior. These hollow mesoporous silica materials are synthesized mainly via soft‐ and hard‐templating routes and are usually modified with a range of organic functional groups (SH, NH2, CN, CH3, CC, benzene, fluorine linked organoalkylsilanes, and ethane‐, amine, benzene, and biphenyl‐bridged silanes) to improve their performance in many applications. This article outlines the most advanced applications of silica‐based and functionalized hollow mesoporous materials that are reported in the last 3 years (January 2014–June 2017). The high applicability of hollow materials in various fields is discussed, including drug delivery and cancer therapy, bioimaging, adsorption/separation, catalysis, thermal and electrical insulators, anticorrosion, sensors, fuel cells, proton conductors, membrane, optics, superhydrophobic surfaces, and fire safety.
Clay Minerals—Ionic Liquids, Nanoarchitectures, and Applications
Authors: Dedzo Gustave Kenne , Detellier Christian 
Published: October 2017

AbstractClay minerals, whose world resources are extremely large, have the potential to be more exploited as the basis for functional materials. Of interest are their interactions with ionic liquids (ILs). These compounds have found a large number of applications in the last few decades due to unique properties, such as low vapor pressure, high thermal stability, and remarkable solvation abilities. In the case of the swelling smectites, the organic cation of ILs can replace interlayer cations and find applications in the preparation of nanocomposites. This feature article is mainly focused on kaolinite, a nonswelling 1:1 phyllosilicate, whose layers are essentially neutral. Consequently, the intercalation of ILs involves both cation and anion. The organic cations can be designed to bear hydroxyl groups that will react with the aluminol internal surface of kaolinite, resulting in ionic liquids not only intercalated but also grafted. The resulting nanohybrid materials are characterized by a fixed, rigid, constrained 2D structure, whose dimension can be tuned by the size of the organic cation, whereas the anion is exchangeable. These materials are used for sensing applications such as the specific detection of anions as well as their quantitative analysis. They are also used as catalyst support for nanoparticles.

Published: October 2017

AbstractThe thin‐film directed self‐assembly of molecular building blocks into oriented nanostructure arrays enables next‐generation lithography at the sub‐5 nm scale. Currently, the fabrication of inorganic arrays from molecular building blocks is restricted by the limited long‐range order and orientation of the materials, as well as suitable methodologies for creating lithographic templates at sub‐5 nm dimensions. In recent years, higher‐order liquid crystals have emerged as functional thin films for organic electronics, nanoporous membranes, and templated synthesis, which provide opportunities for their use as lithographic templates. By choosing examples from these fields, recent progress toward the design of molecular building blocks is highlighted, with an emphasis on liquid crystals, to access sub‐5 nm features, their directed self‐assembly into oriented thin films, and, importantly, the fabrication of inorganic arrays. Finally, future challenges regarding sub‐5 nm patterning with liquid crystals are discussed.

Published: October 2017

AbstractCobalt‐catalyzed sp2 C−H bond functionalization of diarylphosphinamides with heterobicyclic alkenes was demonstrated at room temperature employing commercially available cobalt(II)‐salts. The effectiveness of this strategy was illustrated with the reaction of various 8‐aminoquinoline derived phosphinic amides and 7‐oxa/azabenzonorbornadienes. The reaction conditions exhibited excellent functional group tolerance and high diastereoselectivities. Furthermore, extension of this approach to the preparation of polyaryl cyclic phosphinamides was achieved through the dehydrative ring opening/aromatization sequence.magnified image
Recognizing Through‐Bond and Through‐Space Self‐Exchange Charge/Spin Transfer Pathways in Bis(triarylamine) Radical Cations with Similar Geometrical Arrangements
Authors: Uebe Masashi , Kazama Tatsuya , Kurata Ryohei , Sakamaki Daisuke , Ito Akihiro 
Published: October 2017

AbstractRadical cations of bis(triarylamine)s, 3 and 4, in which the triarylamine redox centers are bridged by an ortho‐phenylene and ortho‐carborane cluster, respectively, have been prepared to elucidate the difference in intramolecular charge/spin‐transfer (ICT/IST) pathway owing to the two different bridging units affording similar geometrical arrangements between the redox centers. Electrochemistry, absorption spectroscopy, VT‐ESR spectroscopy, and DFT calculations reveal that 3.+ and 4.+ are classified into class II and class I mixed‐valence systems, respectively, and therefore, through‐bond and through‐space mechanisms are dominant for the ICT/IST phenomena in 3.+ and 4.+, respectively. Moreover, SQUID measurements for dicationic species provide the fact that virtually no spin‐exchange interaction is observed for spins in 42+, while the antiferromagnetic interaction for spins in 32+, in accordance with the existence of a conjugation pathway for the ortho‐phenylene bridge.
Preparation of Functionalized Diaryl‐ and Diheteroaryllanthanum Reagents by Fast Halogen–Lanthanum Exchange

Published: October 2017

AbstractAryl and heteroaryl halides (X=Br, I) undergo a fast and convenient halogen–lanthanum exchange with nBu2LaMe, which leads to functionalized diaryl‐ and diheteroaryllanthanum derivatives. Subsequent trapping reactions with selected electrophiles, such as ketones, aldehydes, or amides, proceeded smoothly at −50 °C in THF, affording polyfunctionalized alcohols and carbonyl derivatives. Kinetic competition experiments revealed a similar reactivity trend as for Br/Mg exchange, but 106‐times higher rates, making it comparable to Br/Li exchange.
