Allosteric Regulation of the Ligand-Binding Ability of Zinc Porphyrins with Sterically Bulky Shielding Units by Metal Complexation
Authors: Ninomiya Yoshikazu , Kozaki Masatoshi , Suzuki Shuichi , Okada Keiji
Published: August 2014

An artificial allosteric system composed of a zinc porphyrin moiety as a ligand-binding site, diphenylanthracene moieties as sterically bulky shielding units, and bipyridine terminals as Fe(II) ion-binding sites, was designed, synthesized, and characterized. The allosteric system forms an [Fe(bpy)3]-type complex in the presence of Fe(II) ions and induces a large conformational change in the alkyl side chains and shielding units, in which the anthracene groups would cover both the top and bottom of the porphyrin Zn(II) center. Consequently, the ligand-binding ability of the zinc porphyrin unit was allosterically suppressed. We found that the formation of the Fe(II) complex resulted in a 9.5-fold reduction in the binding constant between the zinc porphyrin and 3,5-bis(3,5-di-tert-butylphenyl)pyridine at 20 °C. Comparisons of entropy and enthalpy changes in the absence and presence of Fe(II) ions led to the conclusion that the allosteric suppression was mainly due to the destabilization of the Zn(II)-coordinated complex owing to the steric repulsion between the ligand and the shielding unit.
Variations in ecosystem service value in response to land use changes in the upper water source of Beijing and Tianjin-take Chengde as example
Authors: Jiang Lei , Li Chongyang , Chen Yan
Published: August 2014

Land use changes significantly impacts ecosystem services and functions. The estimation of ecosystem services value is conducive to clarifying the ecological changes in response to LULC changes due to urbanization. Chengde was the upper water source of Beijing and Tianjin, the ecosystem is very fragile. After a series of ecology conservation projects like "returning cropland to forestry", the ecosystem service value increased from 5100.17 x 107 Yuan in 1990 to 5104.08 x 107 Yuan in 2008 respectively, with the average increase of 2.3 x 106 Yuan per year. It is indicated that ecosystem service value has the potential to inform policy decisions by emphasizing the benefits of sustainable ecosystem management. So plans on land use management should be made to maintain a balance between urbanization and ecosystem health.
Activist resistance in neoliberal times: stories from Canada
Authors: Calhoun Avery , Wilson Maureen G , Whitmore Elizabeth
Published: August 2014

Neoliberal efforts to extend the impact of the market on social life have been ongoing for several decades – and so has resistance to these efforts. In this article, key developments and effects of neoliberalism in Canada are outlined, especially those of most significance to social work. Within the current context, the work of civil society organisations is particularly remarkable. Allying with this form of resistance to neoliberalism, the article highlights stories from two such organisations told by the workers themselves. The story by the Disability Action Hall is about people with disabilities developing a collective identity and taking social action. The story by the Pembina Institute is about strategies to resist private amassing of profits from a public resource. The article concludes with a brief review of the work of the two organisations using tools available through the perspective of emancipatory social inquiry.
‘No Border, No Nation, Stop Deportation’: protest against immigration control as empowerment
Authors: Zorn Jelka
Published: August 2014

Social work is seen as a profession developing ethical considerations and arguments to advocate for the right to belong to an organised political community, the right to social security and the right to personal liberties as applicable to all people, regardless of their immigration status. Immigration control is thus seen as a source of unjust policies and practices. Those who find themselves undocumented are supposed to remain invisible and without claims on state or society. This article considers some examples of collective mobilisations (the Erased, No Border, Invisible Workers of the World), empowerment and political subjectivisation of non-citizens and the ways in which activism can challenge the notions of belonging, citizenship and access to social rights. When resisting, people create networks of solidarity and invent new ways of belonging. This could be seen as ‘regularisation from below’: the growing autonomy of the city (as opposed to state definitions of belonging) and de-illegalisation at the micro level (at the city level, access to municipal social services, rights with employers etc).
Water Politics in the Sunshine State: Reportage of the Gold Coast Desalination Project in Two Queensland Dailies, 2006–09
Authors: Herron Veena , Cryle Denis
Published: August 2014

Debates over water and related issues have become prominent in twenty-first century Australia, where global warming is combining with climatic extremes to produce a volatile public and politics. The specific context of the Gold Coast Desalination Project, to be analysed here, was a prolonged drought earlier in the decade that reduced dams in densely populated South-East Queensland to unprecedented levels. This situation in turn triggered water rationing and uncertainty about the capacity of existing infrastructure to supply one of the fastest-growing areas of Australia. During the crisis, the Queensland state government was criticised in the press for mismanagement of water resources before the drought, and for the inadequate water situation, which ultimately led to the construction of a desalination plant. The period of this study covers the plant's construction and implementation. Capable of providing up to 125 million litres of clean, fresh drinking water to the South-East Queensland region every day, the desalination plant — which remains politically contentious — began in 2006 and was operational in early 2009.

Our sufficient conditions are that W has density less than 1 and is uniformly flat in a sense that extends to singular varieties the notion of uniform flatness introduced in [5]. We present an example of Ohsawa showing that uniform flatness is not necessary for extension in the singular case, and find an example showing that, for rather different reasons, uniform flatness is also not necessary in the smooth case. The latter answers in the negative a question posed in [5].

Zum Status von Intertextualität im Mittelalter: Tristan, Lancelot, Francesca da Rimini
Authors: Klinkert Thomas
Published: August 2014

Riassunto

Il termine di intertestualità fu creato da Julia Kristeva e significa, tra l.altro, disseminazione e perdita del senso. Di conseguenza, nella critica letteraria, il concetto dell.intertestualità sensu Kristeva è stato applicato soprattutto nell.analisi di testi moderni, mentre alcuni critici addirittura ne negano la rilevanza per la letteratura medievale. Questo saggio cerca invece di dimostrare tramite l.analisi di tre testi (Il romanzo di Tristano, Le Chevalier de la Charrette, Inferno V) come, già nel Medioevo, dei rapporti intertestuali potessero provocare un effetto di disseminazione. La struttura dei testi letterari può dunque mostrarsi in contraddizione con i presupposti epistemologici di un.epoca che credeva nell.incarnazione del verbo e dunque nella verità assoluta e nel senso garantito da Dio.
Beatrice und die anderen Engel: die Musik (in) der Vita Nova
Authors: Kuhn Barbara
Published: August 2014

Riassunto

Partendo dal fatto paradossale che la Vita Nova possa essere definito un »Buch der Lieder« (Wehle) o »libro dei canti«, pur parlando della musica in senso stretto solo in due luoghi, il presente contributo intende esaminare il rapporto esistente fra il libro e la »musica» in un senso più ampio e proporre una lettura della Vita Nova che mette l’accento proprio sulla musicalità delle poesie dantesche e le sue implicazioni. Le poesie stesse, come Beatrice, »angiola giovanissima«, e come Amore, agiscono come angeli: sono caratterizzate anche loro da cortesia e gentilezza e soprattutto trasmettono dolcezza e beatitudine, confermando così la convinzione medievale secondo cui il linguaggio degli angeli non sarebbe altro che musica, mentre da parte sua la musica - in primo luogo, s’intende, quella liturgica - riuscirebbe a comunicare già sulla terra un’idea del canto degli angeli. Qui, non solo la canzone è ›angelo‹ nel senso etimologico del termine, essendo mandata dall’io a portare un messaggio ai destinatari; non solo porta metaforicamente l’io, la cui lingua parla »quasi come per se stessa mossa«, al cielo. Innanzitutto, come fa vedere la rilettura di alcune ›canzoni‹, il linguaggio poetico riesce a dire l’ineffabile grazie alle sue caratteristiche proprie, che lo distinguono dal linguaggio tanto prosastico quanto prosaico, caratteristiche che ne fanno una specie di linguaggio angelico: è la poesia che con la sua suavitas riesce a superare i limiti del linguaggio umano e a procurare la beatitudine, trasportando coloro che la sanno udire già in vita »oltre la spera«.

Potential of Coplanar X-band GaN-MMIC Power Amplifiers
Authors: Ersoy Erhan , Chevtchenko Serguei , Kurpas Paul , Heinrich Wolfgang
Published: August 2014

While the vast majority of GaN X-band PAs is realized as microstrip circuits, this paper reports design, fabrication and measurement of a coplanar version. The amplifier is processed using the FBH 4-inch GaN-on-SiC technology with 0.25 µm-gate GaN HEMTs. The two-stage power amplifier circuit delivers more than 12 W cw output power at 10 GHz, with a large-signal gain of 20 dB and a final stage drain efficiency of 45%. Benchmarking shows that these are best-in-class values for a coplanar X-band MMIC, which come very close to the state-of-the-art microstrip counterparts.

Incidence and outcomes of women with Hodgkin’s lymphoma in pregnancy: a population-based study on 7.9 million births
Authors: El-Messidi Amira , Patenaude Valerie , Hakeem Ghaidaa , Abenhaim Haim A.
Published: August 2014

Objective: The purpose of our study was to estimate the incidence and maternal and fetal outcomes of Hodgkin’s lymphoma (HL) in pregnancy.

Methods: We carried out a population-based cohort study on all births identified in the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample from 2003 to 2011. We calculated disease incidence and used logistic regression analysis to estimate the adjusted effect of HL on maternal and neonatal outcomes.

Results: There were 638 cases of HL in pregnancy among 7,916,388 births, for an overall incidence of 8.06 per 100,000 births, with no perceivable trend over the 8-year study period. Relative to controls, HL in pregnancy was more common among Caucasians and women aged 25–34 years. After adjusting for baseline characteristics, women with HL in pregnancy were more likely to have preterm births, odds ratio (OR) 1.93 (1.53, 2.42) require postpartum blood transfusion, OR 1.38 (1.05, 1.82), and have venous thromboembolism (VTE), OR 7.93 (2.97, 21.22).

Conclusion: The incidence of HL in pregnancy appears to be higher than previously reported with no temporal trend over an 8-year period. Although there is a greater risk of preterm birth and maternal postpartum blood transfusion and VTE, overall maternal and neonatal major morbidity and mortality does not appear to be increased.
Analysis of shrinkage and creep behaviors in polymer-coated lightweight concretes
Authors: Bideci Alper , Bideci Özlem Sallı , Oymael Sabit , Yıldırım Hasan
Published: August 2014

The creep and shrinkage properties of polymer-coated lightweight concretes were examined. Five-hundred-dose lightweight concretes were produced by coating pumice aggregates with three different polymers (Sonomeric1: SNMC, KB Pur 214: KBP, and Polipol3455: PLP). The 3-, 7-, and 28-day compressive strength values of the obtained lightweight concrete samples were determined, and the 840-h and 12-month creep and shrinkage deformations were measured. It was found that the ductility of the SNMC- and KBP-coated concrete samples increased, while their shrinkage deformation results decreased when compared with the control samples. In contrast, the ductility of PLP concrete samples decreased and the shrinkage deformation became higher. In conclusion, the use of SNMC- and KBP-coated pumice aggregates had a positive effect on the creep and shrinkage properties of the concrete. Furthermore, it was observed that the compressive strength values of the lightweight concretes made of the coated samples were higher than those of the control sample.
Make Your Own Working Models of Heart Valves!
Authors: Hudson Margaret L.
Published: August 2014

Heart valves play a vital role in efficient circulation of the blood, and the details of their physical structure are related crucially to their function. However, it can be challenging for the learner to make the mental connection between anatomical structures of valves and the changing pressure gradients that the valves experience and come to an understanding of valve function. Making your own simple, inexpensive working models allows your students to visualize valve action quickly and easily, and to predict effects on function if valve structure were altered. A link to a video showing use and construction of the working valve models is given.
Vaccine Message Framing and Parents’ Intent to Immunize Their Infants for MMR
Authors: Hendrix Kristin S. , Finnell S. Maria E. , Zimet Gregory D. , Sturm Lynne A. , Lane Kathleen A. , Downs Stephen M.
Published: August 2014

BACKGROUND AND OBJECTIVE:

Emphasizing societal benefits of vaccines has been linked to increased vaccination intentions in adults. It is unclear if this pattern holds for parents deciding whether to vaccinate their children. The objective was to determine whether emphasizing the benefits of measles-mumps-rubella (MMR) vaccination directly to the vaccine recipient or to society differentially impacts parents' vaccine intentions for their infants.

METHODS:

In a national online survey, parents (N = 802) of infants <12 months old were randomly assigned to receive 1 of 4 MMR vaccine messages: (1) the Centers for Disease Control and Prevention Vaccine Information Statement (VIS), (2) VIS and information emphasizing the MMR vaccine's benefits to the child, (3) VIS and information emphasizing societal benefits, or (4) VIS and information emphasizing benefits both to the child and society. Parents reported their likelihood of vaccinating their infants for MMR on a response scale of 0 (extremely unlikely) to 100 (extremely likely).

RESULTS:

Compared with the VIS-only group (mean intention = 86.3), parents reported increased vaccine intentions for their infants when receiving additional information emphasizing the MMR vaccine’s benefits either directly to the child (mean intention = 91.6, P = .01) or to both the child and society (mean intention = 90.8, P = .03). Emphasizing the MMR vaccine’s benefits only to society did not increase intentions (mean intention = 86.4, P = .97).

CONCLUSIONS:

We did not see increases in parents’ MMR vaccine intentions for their infants when societal benefits were emphasized without mention of benefits directly to the child. This finding suggests that providers should emphasize benefits directly to the child. Mentioning societal benefits seems to neither add value to, nor interfere with, information highlighting benefits directly to the child.
Health Care Provider Advice for Adolescent Tobacco Use: Results From the 2011 National Youth Tobacco Survey
Authors: Schauer Gillian L. , Agaku Israel T. , King Brian A. , Malarcher Ann M.
Published: August 2014

BACKGROUND:

Health care providers play an important role in promoting tobacco use abstinence among adolescents. This study aimed to provide nationally representative data on the prevalence of provider tobacco use screening and advice delivered to adolescents. Cessation behaviors and correlates of past year quit attempts among current smokers are also explored.

METHODS:

Data came from the 2011 National Youth Tobacco Survey, a nationally representative school-based survey of adolescents in grades 6 through 12 (n = 18 385). Provider screening and advice were assessed by smoking status and demographic characteristics. Logistic regression was used to assess the association between advice and past year quit attempt.

RESULTS:

The overall prevalence of current tobacco use was 16.6%; 10.8% were current cigarette smokers (3.6% were established smokers, 7.2% were nonestablished smokers); 17.3% were former smokers; and 71.9% were never smokers (22.6% high susceptibility, 77.4% low susceptibility). Among all respondents, the prevalence of being asked about tobacco use by a health care provider was 32.2%; the prevalence of being advised to quit or avoid tobacco was 31.4%. Established smokers were more likely than other groups to report provider assessment of tobacco use and advice. Receipt of advice was associated with a higher adjusted odds of having made a past year quit attempt (odds ratio: 1.47, 95% confidence interval: 1.18–1.82).

CONCLUSIONS:

Less than one-third of adolescents report being asked about tobacco use or being advised not to use tobacco. Increased tobacco use intervention by health care providers is needed to prevent initiation and increase cessation.
Cross-conjugation as a Motif for Organic Non-Linear Optical Molecules

We studied the effect of a cross-conjugated bridging group (χC) on charge-transfer in a push-pull chromophore system. The hyperpolarizability of such molecules was found to be comparable to that of a fully π-conjugated molecule (πC) with the same donor and acceptor. The cross-conjugated moiety was then applied as a pendant to a fully π-conjugated chromophore containing a tricyanopyrroline acceptor (TCP). The addition of a χC moiety did not alter the intrinsic hyperpolarizability and provides an avenue for extending and aiding πC systems. The molecules were examined by X-ray diffraction (XRD), hyper-Raleigh scattering (HRS) and UV-visible (UV-vis) spectroscopy. Experimental results were compared with the predictions of density functional theory (DFT). Cross-conjugated molecules have comparable β values, relative to πC molecules, due to reduced spatial overlap between the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO). Thus, the χC architecture could facilitate independent modification of donor and acceptor strengths while minimizing unfavorable effects on electronic transitions and dipole moments.

Authors: Murali M.G , Rao Arun D. , Ramamurthy Praveen C.
Published: August 2014

A new donor-acceptor structured conjugated polymer (PDODTBI) with trifluoromethylated benzimidazole and benzo[1,2-b;3,4-b']dithiophene (BDT) unit have been designed and synthesized using Stille coupling polymerization reaction. The polymer is highly soluble in common organic solvents such as chloroform, tetrahydrofuran and chlorobenzene with good film forming properties. The structure of the polymer is elucidated by 1H NMR and FTIR spectroscopic techniques. The introduction of a trifluoromethyl group at 4th position of the benzimidazole unit has significantly altered the optical and electrochemical properties of polymer. Polymer film showed broad absorption band in the range of 400-680 nm. Optical band gap of the polymer estimated from the absorption band edge and is found to be ∼1.88 eV. Polymer exhibited deeper HOMO (-5.0 eV) and the LUMO (-3.12 eV) energy levels. Bulk heterojunction (BHJ) solar cell device with PDODTBI as a donor and PC61BM as an acceptor were evaluated.

Published: August 2014

Copper nanoparticles are synthesized successfully through chemical reduction of different copper salts stabilized by Ocimum Sanctum Leaf extract, a natural biopolymer. The resulting copper nanoparticles are characterized by using UV Visible Absorption Spectrometer, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Small Angle X-ray Scattering (SAXS) and Fourier Transform Infrared Spectroscopy (FTIR) experiments. Copper nanoparticles prepared display an absorption peak at around 558 nm. X-ray diffraction analysis shows that the particles are FCC crystalline. SEM and TEM display the formation of copper nanoparticles with an average size of 10 nm. The SAXS studies demonstrate the formation of spherical nanoparticles with bimodal size distribution. The FTIR spectrum analysis has confirmed the presence of functional groups of stabilizer Ocimum Sanctum leaf extract in capping the copper nanoparticles.

Utilizou-se a base de dados da pesquisa Nascer no Brasil. Foram estimadas as razões de produtos cruzados OR brutas e ajustadas entre as características do hospital, maternas e de assistência ao parto com os desfechos: aspiração de vias aéreas e gástrica, uso do oxigênio inalatório, uso de incubadora, contato pele a pele, alojamento conjunto e oferta do seio materno na sala de parto e na primeira hora de vida. Foi observada grande variação das práticas usadas na assistência ao recém-nascido a termo na sala de parto. Práticas consideradas inadequadas como uso de oxigênio inalatório (9,5%), aspiração de vias aéreas (71,1%) e gástrica (39,7%) e uso de incubadora (8,8%) foram excessivamente usadas. A ida ao seio na sala de parto foi considerada baixa (16,1%), mesmo nos hospitais com título de Hospital Amigo da Criança (24%). Esses resultados sugerem baixos níveis de conhecimento e aderência às boas práticas clínicas.

Published: August 2014

O transumanismo é uma controversa perspectiva de investimento na transformação da condição humana. Visando ao melhoramento biotecnológico da natureza humana, ele protagoniza o debate acerca do futuro (pós-)humano. Na base da concepção transumanista está o investimento na biotecnociência como um modo de Iluminismo humanista de raízes biológicas. O objetivo do artigo é analisar o debate sobre o futuro da humanidade. Para tanto, apresentamos a perspectiva transumanista, ressaltando definições, características, valores e principais argumentos, analisando o conceito de natureza humana, pois ele é fundamental na polarizada discussão travada entre os transumanistas e bioconservadores. Nossas principais conclusões apontam para a impertinência dessa polarização, bem como do uso do conceito de natureza humana e pós-humano para esclarecer o tema do melhoramento humano. Assim, cumpre despolarizar o debate e apostar otimista e prudentemente no futuro biotecnológico.
Os sentidos e disputas na construção da Política Nacional de Promoção da Saúde
Authors: Silva Patrícia Ferrás Araújo da , Baptista Tatiana Wargas de Faria
Published: August 2014

Este estudo teve como objetivo analisar a definição da Política Nacional de Promoção da Saúde de 2006 no Brasil, buscando explicitar os sentidos e disputas no processo de formulação e suas implicações para o campo da saúde. Para tanto, foram feitas revisão bibliográfica, análise de documentos e entrevistas com participantes da rede de discussão sobre promoção da saúde no Brasil. Partimos de uma visão de ciência construcionista, compreendendo a política como um processo dinâmico que se constitui a partir de diferentes fatores que influenciam as escolhas e posicionamentos dos atores e grupos. Identificamos no processo alguns tensionamentos que podem ser entendidos como dilemas que o debate da promoção suscita. Um primeiro dilema apresentou-se no debate propriamente dito em torno do modelo de promoção, que decorre da polarização historicamente construída entre a perspectiva regulatória e a perspectiva emancipatória. Um segundo dilema refere-se à apropriação desta polarização se desdobrando na discussão entre o amplo e o restrito, onde as propostas voltadas para o coletivo são tidas como comprometidas com um projeto emancipatório e as propostas voltadas para o individual são entendidas numa perspectiva de controle. O terceiro dilema se traduziu no emprego do conceito de empowermentsem uma discussão aprofundada de seus efeitos no processo de construção desta política em nosso âmbito.

Published: August 2014

El objetivo del trabajo es analizar la elaboración y aplicación de la perspectiva de género en las políticas de seguridad pública efectuadas por el Ministerio de Justicia y Seguridad de la Provincia de Buenos Aires (Argentina) en la primera década del siglo XXI. Analizo las estrategias utilizadas como así la interacción de diversos agentes que tienen el objetivo de forjar definiciones sobre género y políticas de género e instituir formas de actuación frente a denuncias de violencia familiar. A través del análisis de estos aspectos muestro, por un lado, que desde lo conceptual, las políticas de género despiertan múltiples sentidos, y por otro lado, señalo las reservas que tienen los propios actores que intervienen en la ejecución de tales políticas. Al analizar la implementación de estas políticas en una Comisaría de la Mujer y la Familia en una localidad, indico que las mismas tienen una ejecución particular de acuerdo a los actores que allí intervienen.
Three-dimensional characterisation of particle size and shape for ballast
Authors: Sun Y. , Indraratna B. , Nimbalkar S.
Published: August 2014

The size and shape of particles influence how effectively coarse angular aggregates of ballast interact. The aim of this study was to improve the characterisation of ballast particles using a three-dimensional (3D) imaging method. Various size and shape indices, such as elongation ratio, sphericity and roundness, were determined from the scanned 3D images. A modified index called ‘ellipsoidness’ was proposed to capture adequately the shape of the 3D particles. Variation of these indices with particle size was studied. Comparison of the 3D true sphericity and the corresponding two-dimensional sphericity indicated that the latter would underestimate sphericity. A modified approach for transforming particle size distribution to constriction size distribution is proposed by capturing the size and shape effects of particles.
Medication Health Literacy Measure: Development and Psychometric Properties
Authors: Stilley Carol S. , Terhorst Lauren , Flynn William B. , Fiore Roberta M. , Stimer Erin D.
Published: August 2014

Background and Purpose: Low levels of health literacy are prevalent worldwide. This report details development and psychometric properties of a health literacy measure for oral medications based on design of the Newest Vital Sign. Methods: The measure was completed during the baseline interview. A principal components analysis evaluated dimensionality of the measure. Cronbach’s alpha assessed subscale internal consistencies. Results: Internal consistencies and reliability for the subscales were acceptable for a new instrument (α = .661, α = .686, α = .400). A 3-factor structure explained 65.34% of the total variance. Divergent validity with the Rapid Estimate of Adult Literacy in Medicine (REALM) was established. Conclusions: Our data indicates that the medication health literacy tool is multidimensional, valid, and reliable. This information is important in light of emerging evidence of the impact of health literacy on medication adherence and health.

Background and Purpose: Patient care is changing rapidly with increased complexity of care, patient volumes, and financial constraints with rising health care costs and limited reimbursements. In response, the clinical nurse leader (CNL) role was developed. No appropriate instrument exists to measure staff satisfaction with the CNL role. This study describes the development and testing of an instrument designed to measure staff satisfaction with implementation of the CNL role. Methods: The psychometric properties and factor structure of the Clinical Nurse Leader Staff Satisfaction (CNLSS) instrument was examined. Results: A 2-factor solution was discovered for the CNLSS. Cronbach’s alpha coefficients were acceptable for the subscales and instrument. Conclusion: The CNLSS is a valid and reliable instrument. Future research should focus on establishing test–retest reliability and construct validity.

Published: August 2014

Faculty development that builds research capacity is a significant yet challenging expectation in academia. The School of Nursing faculty at Ryerson University established several research clusters to support research collaborations and productivity. This article explicates one cluster's development process, and specifically, its adoption of the narrative reflective process (NRP). Engaging in NRP permitted the group to creatively enter into critical dialogue, address both individual and collective needs, and establish a supportive environment that nurtures the creative process—all of which ultimately enhances scholarship and academic productivity.
Confronting 60 Minutes’ “Imminent Danger”: The Evidence on Schizophrenia and Psychotropic Medications, Violence, and Forced Orders to Treat
Authors: Watson Toby T.
Published: August 2014

Recently, considerable attention has been given to individuals labeled “mentally ill,” with the possibility that they too often go untreated with psychotropic medications and in turn, commit disproportionally higher rates of violence. The world-known television show60 Minutesbroadcasted a special on this topic in the United States on September 29, 2013; however, they created a disturbingly inaccurate picture of those who suffer with what some label as “mental illness.” There are decades of peer-reviewed research demonstrating that individuals diagnosed with severe mental illness, labeledschizophrenia,and given psychotropic medications are in fact less likely to recover from their disorder and more likely to be rehospitalized. Additionally, although mental health commitments, often calledforced orders to treat,are quite common and now being supported more so due to such programming, the research on mental health commitments has not shown they are actually effective.

Authors: Strauser David R. , Wagner Stacia , Chan Fong , Wong Alex W. K.
Published: August 2014

Purpose: Identify barriers to career development and employment from both the survivor and parent perspective.

Method: Young adult survivors (N = 43) and their parents participated in focus groups to elicit information regarding perceptions regarding career development and employment.

Results: Perceptions of both the young adults and parents indicate that there is a significant need for comprehensive career and employment services targeted for young adult central nervous system cancer survivors.

Conclusions: Findings provide initial evidence and support for the need to incorporate career and vocational services into psychosocial treatment programs. More research is needed in this area to gain an understanding of the specific career and vocational needs and to further explore how the interaction between the young adults and their parents impact vocational outcomes.
Digital Image Analysis Method for Estimation of Fusarium‐Damaged Kernels in Wheat

Published: August 2014

Fusarium head blight (FHB) of wheat (Triticum aestivum L.), or head scab, causes a reduction in grain yield and quality through the formation of shriveled, dull‐grey seeds called “tombstones” or Fusarium‐damaged kernels (FDK). Fusarium‐damaged kernels are commonly quantified on a percentage basis by visually separating damaged from healthy kernels following harvest, in a process that is both time consuming and labor intensive. The objective of this study was to evaluate an alternative method for quantifying FDK through the use of the digital image analysis program ImageJ. The ‘NC‐Neuse’ × ‘AGS 2000’ F5–derived recombinant inbred population of 172 lines and the NC‐Neuse ×‘Bess’ double haploid population of 112 lines were used in this study. NC‐Neuse and Bess were moderately resistant and AGS 2000 was susceptible to FHB. The populations were evaluated under moderate to heavy FHB epidemics in a total of five environments in North Carolina, Maryland, and Missouri with two to three replications per environment during the 2010 to 2011 and 2011 to 2012 seasons. Following hand harvest and grain processing, FDK was estimated by (i) visual separation of diseased kernels and (ii) digital image analysis using ImageJ on captured images of grain samples. The correlation between the two methods ranged from 0.72 to 0.80 over five environments. A lower correlation was observed in one environment due to cracked and broken kernels in the samples. Digital image analysis was three times faster than the visual method and estimated FDK on a larger scale per plot sample, whereas labor and time constraints limited the sample size for the visual method. Digital image analysis was consistent over samples and appears well suited as an alternative form to estimate percent of FDK in grain that is not damaged in other ways.
Scaling function based on Chinese remainder theorem applied to a recursive filter design
Authors: Stamenkovic Negovan , Zivaljevic Dragana , Stojanovic Vidosav
Published: August 2014

Implementation of IIR filters in residue number system (RNS) architecture is
more complex in comparison to FIR filters, due to introduction of the
scaling function. This function performs operation of division by a constant
factor, which is usually the power of two, and after that the operation of
rounding. In that way dynamic range reduction in digital systems is
achieved. There are different methods for scaling operation implementation,
already presented in references. In this paper, some RNS dynamic reduction
techniques have been analyzed and then application of one selected technique
has been presented on example. In all RNS calculations the power of two
moduli set {2n-1, 2n, 2n+1} has been applied.
EERA and its European Conferences on Educational Research: A Patchwork of Research on European Educational Research
Authors: Keiner Edwin , Hofbauer Susann
Published: August 2014

The process of Europeanisation is closely linked to the process of an emerging European Educational Research Area and an education research identity. The European Conferences on Educational Research (ECER), European Educational Research Association (EERA) and its networks are involved in new directions and strands of educational research in particular European nations as well as in processes to construct a common European Educational Research Area. ECER to a large extent contributes to such developments both as observer and actor. Against the background of diverse functions and contexts of ECER for communication on and development of educational research in Europe, the authors describe some small-scale research studies about ECER that have been carried out during the past ten years dealing with attendance motives and assessments of ECER, and provide content analyses of proposal abstracts of ECER. In doing so, they would like to present a mirror to EERA at its 20th anniversary that could contribute to further systematic self-observation and self-governance of EERA and ECERs as vivid, inspiring, powerful, discursive, democratic and scholarly high-standing conferences in the future.
A Case Report of Gingival Enlargement Associated With Invasive Cervical Resorption
Authors: Bal MV , Yıldırım Ş , Saygun I
Published: August 2014

Invasive cervical resorption (ICR) is a rare external dental resorption with unknown etiology; it progresses asymptomatically in the cervical area of the permanent teeth. Lesions are mostly misdiagnosed as internal resorption or caries, which leads to erroneous treatments. This case report presents the clinical and radiological diagnosis, as well as the results of treatment and 3-year follow-up in a 50-year-old female patient with gingival enlargement associated with ICR in tooth No. 25. Granulation tissue was removed by accessing the cervical resorption area through a flap operation. Following the endodontic treatment, the tooth was restored using composite resin and the hyperplastic lesion was excised. In conclusion, it should be kept in mind that clinical, radiological, and pathological evaluation in the differential diagnosis of localized hyperplastic lesions in the gingiva is of importance and that ICR could play a role in the etiology of these lesions.
Adsorption Kinetics of Reactive Dyes on Ash from Town Heating Plant
Authors: Djordjevic Dragan , Stojiljkovic Dragan , Smelcerovic Miodrag
Published: August 2014

In order to investigate the mechanism of adsorption of reactive dyes from the textile industry on ash from heating plant produced by brown coal combustion, some characteristic sorption constants are determined using Langergren adsorption equations for pseudo-ﬁ rst and pseudo-second order. Combined kinetic models of pseudo-ﬁrst order and pseudo-second order can provide a simple but satisfactory explanation of the adsorption process for a reactive dye. According to the characteristic diagrams and results of adsorption kinetic parameters of reactive dyes on ashes, for the applied amounts of the adsorbents and different initial dye concentrations, it can be concluded that the rate of sorption is fully functionally described by second order adsorption model. According to the results, the rate constant of pseudo-second order decreases with increasing initial dye concentration and increases with increasing amount of adsorbent – ash.
Surface Properties of Particles Emitted from Selected Coal-Fired Heating Plants and Electric Power Stations in Poland: Preliminary Results
Authors: Pastuszka Józef S. , Konieczyński Jan , Talik Ewa
Published: August 2014

The surface properties of particles emitted from six selected coal-fired power and heating plants in Poland have been studied in this work for the first time. Samples were collected beyond the control systems. Surface composition of the size-distributed particles was obtained by photoelectron spectroscopy (XPS).

The reflection of the smallest, submicron particles was also measured to calculate their specific/mass absorption. The surface layer of the emitted particles was clearly dominated by oxygen, followed by silicon and carbon. The sum of the relative concentration of these elements was between 85.1% and 91.1% for coarse particles and 71.8–93.4% for fine/submicron particles. Aluminum was typically the fourth or fifth, or at least the sixth most common element. The mass absorption of the submicron particles emitted from the studied plants ranged from 0.02 m2g-1 to 0.03 m2g-1. Only specific absorption obtained for the “Nowy Wirek” heating plant was significantly higher than in other studied plants probably because the obsolete fire grate is used in this heating plant.

The obtained results suggest that the power/heating-plant-emitted fine particles contain less carbonaceous material/elemental carbon on their surfaces than those that are typical in urban air.
