Polarization maps of the Vela C molecular cloud were obtained at 250, 350, and 500 μm during the 2012 flight of the balloon-borne telescope BLASTPol. These measurements are used in conjunction with 850 μm data from Planck to study the submillimeter spectrum of the polarization fraction for this cloud. The spectrum is relatively flat and does not exhibit a pronounced minimum at λ ∼ 350 μm as suggested by previous measurements of other molecular clouds. The shape of the spectrum does not depend strongly on the radiative environment of the dust, as quantified by the column density or the dust temperature obtained from Herschel data. The polarization ratios observed in Vela C are consistent with a model of a porous clumpy molecular cloud being uniformly heated by the interstellar radiation field.

We introduce the Baryon Oscillation Spectroscopic Survey (BOSS) Emission-Line Lens Survey GALaxy-Lyα EmitteR sYstems (BELLS GALLERY) Survey, which is a Hubble Space Telescope program to image a sample of galaxy-scale strong gravitational lens candidate systems with high-redshift Lyα emitters (LAEs) as the background sources. The goal of the BELLS GALLERY Survey is to illuminate dark substructures in galaxy-scale halos by exploiting the small-scale clumpiness of rest-frame far-UV emission in lensed LAEs, and to thereby constrain the slope and normalization of the substructure-mass function. In this paper, we describe in detail the spectroscopic strong-lens selection technique, which is based on methods adopted in the previous Sloan Lens ACS (SLACS) Survey, BELLS, and SLACS for the Masses Survey. We present the BELLS GALLERY sample of the 21 highest-quality galaxy–LAE candidates selected from

galaxy spectra in the BOSS of the Sloan Digital Sky Survey III. These systems consist of massive galaxies at redshifts of approximately 0.5 strongly lensing LAEs at redshifts from 2–3. The compact nature of LAEs makes them an ideal probe of dark substructures, with a substructure-mass sensitivity that is unprecedented in other optical strong-lens samples. The magnification effect from lensing will also reveal the structure of LAEs below 100 pc scales, providing a detailed look at the sites of the most concentrated unobscured star formation in the universe. The source code used for candidate selection is available for download as a part of this release.
INFALLING–ROTATING MOTION AND ASSOCIATED CHEMICAL CHANGE IN THE ENVELOPE OF IRAS 16293–2422 SOURCE A STUDIED WITH ALMA

Published: June 2016

We have analyzed rotational spectral line emission of OCS, CH3OH, HCOOCH3, and H2CS observed toward the low-mass Class 0 protostellar source IRAS 16293–2422 Source A at a sub-arcsecond resolution (∼0.″6 × 0.″5) with ALMA. Significant chemical differentiation is found on a scale of 50 au. The OCS line is found to trace well the infalling–rotating envelope in this source. On the other hand, the distributions of CH3OH and HCOOCH3 are found to be concentrated around the inner part of the infalling–rotating envelope. With a simple ballistic model of the infalling–rotating envelope, the radius of the centrifugal barrier (a half of the centrifugal radius) and the protostellar mass are evaluated from the OCS data to be from 40 to 60 au and from 0.5 to 1.0 M
⊙, respectively, assuming the inclination angle of the envelope/disk structure to be 60° (90° for the edge-on configuration). Although the protostellar mass is correlated with the inclination angle, the radius of the centrifugal barrier is not. This is the first indication of the centrifugal barrier of the infalling–rotating envelope in a hot corino source. CH3OH and HCOOCH3 may be liberated from ice mantles by weak accretion shocks around the centrifugal barrier and/or by protostellar heating. The H2CS emission seems to come from the disk component inside the centrifugal barrier in addition to the envelope component. The centrifugal barrier plays a central role not only in the formation of a rotationally supported disk but also in the chemical evolution from the envelope to the protoplanetary disk.

Neste contexto, o Problema de Corte de Estoque com Aproveitamento de Sobras (PCES) enfoca tal questão visando a melhor utilização da matéria-prima, ou seja, utilizar as sobras em um processo de corte futuro, desde que elas apresentem condições para isso. Buscamos com este trabalho determinar soluções inteiras para um PCES por meio de um estudo computacional dos modelos matemáticos propostos por Pinto (2008). Exploramos também uma reformulação do modelo matemático da Estratégia 5 de Pinto (2008), a qual denominamos Estratégia 5 Reformulada (5R). Analisamos a eficácia dos modelos, considerando critérios de avaliação estabelecidos, a priori, pela comparação dos resultados com os resultados de heurísticas propostas por Cherri e outros (2009), por meio de simulações computacionais realizadas em um conjunto de classes de exemplares gerados aleatoriamente. Os resultados mostram que, conforme as classes vão crescendo em termos de dimensão e demanda dos exemplares, a concentração dos melhores resultados tende para a Estratégia 5R e para os procedimentos heurísticos, em particular para os residuais RAGR1, RAGR2 e RAGR3.

O gerenciamento de projetos tem sido uma abordagem com acelerada difusão nas últimas três decadas nas organizações de diversos segmentos do mercado no Brasil e no mundo. Apesar da ampla divulgação  e utilização, ainda é alto o índice de insucesso ou sucesso parcial na execução dos emprendimentos. Como esse campo de estudo é recente, levou-se ao questionamento se esse índice é consequência da imaturidade das organizações na utilização dos conhecimentos, técnicas e habilidades dessa área. Este estudo, realizado a partir de pesquisa bibliográfica, tem como objetivo comparar e identificar as diferenças conceituais dos modelos Organizational Project Management Maturity Model® (OPM3®) e Kerzner Project Managemente Maturity Model® (KPMMM®) utilizadas para avaliação da maturidade em gerenciamento de projetos nas organizações. A comparação dos métodos OPM3® e KPMMM®, com base em revisão bibliográfica, permite concluir que há complementaridade entre as duas abordagens e algumas diferenças, o que possibilita que o modelo KPMMM® possa ser aplicado em combinação com o OPM3®, para assim maximizar os resultados ao mesmo tempo definir um foco para as primeira análises, o que possibilita economizar, recursos e reduzir o tempo para obter indicações para melhorias.

A função compras é estratégica para as empresas já que pode promover redução de custos no processo de suprimento e permitir que os materiais utilizados na produção estejam sempre disponíveis no momento e em quantidade desejados. Como consequência de uma gestão de compras adequada, as empresas podem aumentar sua competitividade com essa potencial redução de custos e aumento da eficiência em seu suprimento. As empresas do setor elétrico no Brasil, em virtude da recente crise energética, dentre outros motivos, buscam redução de gastos com a geração e transmissão de energia para tornar o setor mais competitivo no país. Neste contexto, a função compras pode contribuir, sobretudo, na gestão adequada dos suprimentos nesse setor que, algumas vezes, encontra dificuldades para manter o fornecimento contínuo de energia, o que resulta em multas e perda da qualidade no serviço prestado ao consumidor. Assim, este artigo propõe um sistema de suporte à decisão para gestão de compras públicas em regime de Registro de Preços. Para tanto, utilizou-se como objeto de estudo uma empresa do setor elétrico situada no estado do Pará. O sistema proposto corresponde a um módulo computacional adicionado ao sistema usado na empresa, tendo por objetivo auxiliar o gerenciamento do ressuprimento de materiais através do controle da vigência dos processos de compras, bem como das informações pertinentes à execução de tais processos. A partir da implantação do sistema proposto na empresa estudada, foi possível observar melhorias, como a redução de tempo e custos na geração e gestão dos processos de compras.

Published: June 2016

Objective.

Total hip arthroplasty (THA) is performed more frequently in patients with systemic lupus erythematosus (SLE) than in the general population. However, whether patients with SLE have higher complication rates than patients with osteoarthritis (OA) is unknown. This study compares adverse events (AE) in SLE with OA controls.

Methods.

Patients in our institution’s registry were eligible. SLE was identified by the International Classification of Diseases, 9th ed code. AE were identified by chart review and questionnaire. Patients with SLE were matched with OA controls. Multivariate regression was performed to identify independent predictors of AE.

Results.

Fifty-eight patients with SLE THA were matched with 116 OA controls. Of the patients with SLE, 47.4% had Charlson-Deyo comorbidity scores (excluding SLE) > 1 versus 13.1% of OA (p < 0.0001). Length of stay was longer for SLE (6.0 days vs 4.7 days, p = 0.0008). Patients with SLE had more falls (10.3% vs 1.7%, p = 0.017), deep vein thrombosis (5.2% vs 0%, p = 0.036), acute renal disease (8.6% vs 0%, p = 0.004), wound infections (6.9% vs 0.9%, p = 0.043), and revision surgeries (5.2% vs 0%, p = 0.036). In a logistic regression controlling for comorbidities, SLE had an increased risk of AE (OR 3.77, 95% CI 1.74–8.16). Comorbidity scores were not significantly associated with AE. Among those with SLE, there were no significant differences in AE in those taking corticosteroids.

Conclusion.

SLE is an independent risk factor for AE after THA. Patients with SLE had higher rates of falls, acute renal disease, infections, and revision surgeries than matched OA controls. Further research is needed to understand the causes of increased AE in patients with SLE.
Comparison of CAROC and FRAX in Fragility Fracture Patients: Agreement, Clinical Utility, and Implications for Clinical Practice
Authors: Rotondi Nooshin Khobzi , Beaton Dorcas E. , Elliot-Gibson Victoria , Sujic Rebeka , Josse Robert G. , Sale Joanna E.M. , Leslie William D. , Bogoch Earl R.
Published: June 2016

Objective.

To examine the level of agreement between 2 fracture risk assessment tools [Canadian Association of Radiologists and Osteoporosis Canada (CAROC) and Canadian Fracture Risk Assessment (FRAX)] when applied within the context of the Canadian guidelines, in a population of fragility fracture patients.

Methods.

The sample consisted of 135 treatment-naive fragility fracture patients aged 50+ years and screened as part of an osteoporosis (OP) program at an urban hospital. Ten-year probabilities of future major osteoporotic fractures were calculated using the FRAX and CAROC. We also integrated additional qualifiers from the 2010 Canadian guidelines that place hip, spine, and multiple fractures at high risk regardless. A quadratic weighted κ (Kw) and 95% CI were calculated to estimate the chance corrected agreement between the risk assessment tools. Logistic regression was used to evaluate the factors associated with concordance.

Results.

Among patients with fragility fractures, the agreement between CAROC and FRAX was Kw = 0.64 (95% CI 0.58–0.71), with 45 of 135 cases in the cells reflecting disagreement. Younger persons and males were more likely to be found in discordant cells.

Conclusion.

The level of agreement between 2 commonly used fracture risk assessment tools was not as high in the patients with fragility fractures as it was in general community-based samples. Our results suggest discordance is found in less-typical patients with OP who need more consistency in messaging and direction. Users of these fracture risk tools should be aware of the potential for discordance and note differences in risk classifications that may affect treatment decisions.

Published: June 2016

Objective.

Prior studies investigating the efficacy of oral treprostinil to treat digital ulcers (DU) in systemic sclerosis (SSc)-associated Raynaud phenomenon have yielded conflicting results. In this investigation, we examined whether DU burden increased after patients withdrew from oral treprostinil that was administered during an open-label extension study.

Methods.

A multicenter, retrospective study was conducted to determine DU burden in the year after withdrawal from oral treprostinil. DU burden 3–6 months (Time A) and > 6–12 months (Time B) after drug withdrawal was compared with DU burden at baseline, defined as the last day receiving drug in the open-label extension study, by a paired Student t test. Changes in DU burden while receiving drug in the open-label study were compared with changes in DU burden at Time B by a paired Student t test.

Results.

Fifty-one patients from 9 clinical sites were included for analysis. DU burden increased significantly from baseline (mean 0.47) to Time A (mean 2.1, p = 0.002, n = 23) and Time B (mean 1.45, p = 0.013, n = 30). Total DU burden decreased during oral treprostinil exposure (mean change −0.6) and then increased by Time B (mean change 1.05, p = 0.0027 for comparison, n = 30). In the year after drug withdrawal, many patients required vasodilator therapy and pain medications. Three patients were hospitalized for complications from DU, and 4 patients required surgery for DU.

Conclusion.

Total DU burden increased significantly after discontinuation of oral treprostinil. These data provide supportive evidence of a beneficial effect of oral treprostinil for the vascular complications of SSc and suggest that further study is warranted.
Summed and Weighted Summary Scores for the Medsger Disease Severity Scale Compared with the Physician’s Global Assessment of Disease Severity in Systemic Sclerosis
Authors: Harel Daphna , Hudson Marie , Iliescu Alexandra , Baron Murray ,   Canadian Scleroderma Research Group, Steele Russell
Published: June 2016

Objective.

To develop a weighted summary score for the Medsger Disease Severity Scale (DSS) and to compare its measurement properties with those of a summed DSS score and a physician’s global assessment (PGA) of severity score in systemic sclerosis (SSc).

Methods.

Data from 875 patients with SSc enrolled in a multisite observational research cohort were extracted from a central database. Item response theory was used to estimate weights for the DSS weighted score. Intraclass correlation coefficients (ICC) and convergent, discriminative, and predictive validity of the 3 summary measures in relation to patient-reported outcomes (PRO) and mortality were compared.

Results.

Mean PGA was 2.69 (SD 2.16, range 0–10), mean DSS summed score was 8.60 (SD 4.02, range 0–36), and mean DSS weighted score was 8.11 (SD 4.05, range 0–36). ICC were similar for all 3 measures [PGA 6.9%, 95% credible intervals (CrI) 2.1–16.2; DSS summed score 2.5%, 95% CrI 0.4–6.7; DSS weighted score 2.0%, 95% CrI 0.1–5.6]. Convergent and discriminative validity of the 3 measures for PRO were largely similar. In Cox proportional hazards models adjusting for age and sex, the 3 measures had similar predictive ability for mortality (adjusted R2 13.9% for PGA, 12.3% for DSS summed score, and 10.7% DSS weighted score).

Conclusion.

The 3 summary scores appear valid and perform similarly. However, there were some concerns with the weights computed for individual DSS scales, with unexpected low weights attributed to lung, heart, and kidney, leading the PGA to be the preferred measure at this time. Further work refining the DSS could improve the measurement properties of the DSS summary scores.
Infection in Southern Chinese Patients with Systemic Lupus Erythematosus: Spectrum, Drug Resistance, Outcomes, and Risk Factors
Authors: Chen Dongying , Xie Jingyi , Chen Haihong , Yang Ying , Zhan Zhongping , Liang Liuqin , Yang Xiuyan
Published: June 2016

Objective.

To investigate the spectrum, antibiotic-resistant pattern, risk factors, and outcomes of infection in patients hospitalized with systemic lupus erythematosus (SLE).

Methods.

We collected the clinical and microbiological data from hospitalized patients with SLE with infection between June 2005 and June 2015, and then conducted retrospective analyses.

Results.

Among our sample of 3815 hospitalized patients, 1321 (34.6%) were diagnosed with infection. The majority (78.3%) of infection occurred within 5 years of SLE onset. Bacterial infection was predominant (50.6%), followed by viral infection (36.4%) and fungal infection (12.5%). The lungs (33.7%) and upper respiratory tracts (26.3%) were most commonly affected. Gram-negative bacteria (GNB) were predominant over gram-positive bacteria (178 isolates vs 90 isolates). The most frequently isolated bacteria were Escherichia coli (24.6%), followed by Acinetobacter baumannii (13.4%) and coagulase-negative Staphylococcus (13.4%). Multidrug-resistant (MDR) strains were detected in 26.9% of bacterial isolates. The most common fungus was Candida spp. (99 episodes), followed by Aspergillus (24 episodes) and Cryptococcus neoformans (13 episodes). The overall mortality rate for this cohort was 2.2%; 48 patients died of infection. Factors associated with bacterial and viral infection were higher Systemic Lupus Erythematosus Disease Activity Index, renal involvement, thrombocytopenia, accumulated dose of glucocorticoids (GC), and treatment with cyclophosphamide (CYC). Renal involvement, accumulated dose of GC, and treatment with CYC were associated with fungal infection.

Conclusion.

Infection was the leading cause of mortality in patients hospitalized with SLE. There were some notable features of infection in Chinese patients including early onset, higher proportion of respiratory tract involvement, predominance of GNB with emergence of MDR isolates, and a variety of pathogens.

Published: June 2016

Objective.

The termscleroderma patterntypically defines capillary abnormalities of scleroderma spectrum disorders, mainly systemic sclerosis (SSc) and dermatomyositis (DM). Our study aimed to investigate differences in nailfold videocapillaroscopy (NVC) between DM and SSc, with a cross-sectional and longitudinal evaluation.

Methods.

NVC features of 29 consecutive patients with DM were compared with 90 patients with SSc categorized into the 3 subsets of scleroderma pattern: early, active, and late. Twenty patients with DM and all with SSc were also longitudinally reevaluated after 30 months of followup.

Results.

At baseline, all SSc groups showed giant capillaries, with significant differences with DM only for early and active pattern. Ramified capillaries were significantly more frequent and severe in DM than in early and active patterns, while DM showed an opposite trend compared with late pattern. Capillary loss was lower in early pattern and higher in active and late, compared with DM. Finally, giant-ramified capillaries were almost exclusive of DM. During followup, NVC showed a different evolution in DM and SSc. In DM we recorded a reduction of giant capillaries, while ramified capillaries increased both in DM and in early and active SSc pattern. The number of capillaries recovered in DM; conversely, capillary loss slightly worsened in all SSc patterns. Giant-ramified capillaries significantly decreased in patients with DM, remaining rare in patients with SSc.

Conclusion.

Our study strengthens the specificity of DM and SSc microangiopathy and points out the need for large prospective studies to confirm our results and possibly to revise current terminology by distinguishing between “scleroderma” and “dermatomyositis” patterns.
La pédalisation au pianoforte et la pratique de l’accompagnement des romances françaises vers 1800
Authors: Verwaerde Clotilde
Published: June 2016

L’usage des pédales au pianoforte a fait l’objet de plusieurs études récentes, mais ces dernières s’appuient principalement sur le répertoire soliste. Cet article vise à replacer ce mode de jeu parmi les techniques d’accompagnement au clavier dans la musique vocale, notamment la romance française autour de 1800. Des exemples, extraits de romances mises en musique entre autres par Adrien Boieldieu, Gabriel Lemoyne, et Félix Blangini, montrent de quelle façon les images sonores inhérentes à ce mode de jeu particulier sont employées en lien étroit avec la signification du texte ou l’atmosphère qu’il crée. L’intérêt se concentre plus spécifiquement sur des œuvres dont le texte est issu ou inspiré des romans gothiques anglais, afin d’observer les conditions de mise en œuvre du tremendo dans l’accompagnement, une technique caractéristique de l’école française qui requiert l’emploi des pédales et fait référence au topos de la mort.
Pour une sociologie des répertoires d’actions électorales
Authors: Desrumaux Clément , Lefebvre Rémi
Published: June 2016

Pour analyser les pratiques, les techniques et les savoirs mobilisés lors des campagnes électorales, cet article propose l’usage de la notion de répertoires d’actions électorales . La littérature sur les campagnes électorales est généralement dominée par des considérations d’efficience électorale et les changements observés dans les pratiques sont principalement liés à des évolutions technologiques. La notion de répertoires d’actions électorales permet d’analyser les choix produits par les agents dans un contexte où « le choix des armes » est structuré historiquement et sociologiquement. Les agents puisent dans des répertoires d’actions électorales en fonction de contextes politiques enserrés dans des cadres légaux, en fonction aussi de leur appartenance partisane et du rapport de force interne aux partis. La notion de répertoire permet aussi d’expliquer les mobilisations électorales en tenant compte des trajectoires des agents mobilisés et des interactions qu’ils entretiennent avec leurs publics. Enfin, il s’agit aussi d’analyser les évolutions historiques et géographiques des répertoires en lien avec des croyances qui entourent les modes d’action et les phénomènes de circulation dont ils font l’objet.
Les représentant.e.s d’intérêt et la campagne présidentielle de 2012. Rapports au politique et formes de coopération avec les candidat.e.s
Authors: Courty Guillaume , Gervais Julie
Published: June 2016

L’élection présidentielle de 2012 a fait l’objet d’un protocole de recherche original visant à observer les pratiques d’agents peu étudiés de l’élection : les représentant.e.s d’intérêt. L’article porte sur les sollicitations que les groupes mobilisés en campagne ont adressées aux candidat.e.s et à leurs équipes (soit des revendications, des invitations, des propositions, des requêtes ou encore des questionnaires). Il en ressort notamment que ce qui préside à la coopération des agents politiques et des représentant.e.s d’intérêt tient avant tout à la position sociale homologue qu’ils détiennent dans leurs espaces respectifs ainsi qu’aux compétences politiques de ces dernier.e.s.
Physician Utilization Patterns for VEGF-Inhibitor Drugs in the 2012 United States Medicare Population: Bevacizumab, Ranibizumab, and Aflibercept
Authors: Baisiwala Shivani , Bundorf M. Kate , Pershing Suzann
Published: June 2016

BACKGROUND AND OBJECTIVE:

To evaluate variation in physician use of vascular endothelial growth factor (VEGF) inhibitors.

PATIENTS AND METHODS:

Population-based analysis of comprehensive, publicly available 2012 Medicare claims, aggregated by physician specialty and service type — including intravitreal injections of bevacizumab (Avastin; Genentech, South San Francisco, CA), ranibizumab (Lucentis; Genetech, South San Francisco, CA), and aflibercept (Eylea; Regeneron, Tarrytown, NY). Physicians were characterized by total patients treated, proportion treated with each drug, total intravitreal injection payments, and proportion of total payments for each drug.

RESULTS:

The authors identified 2,869 ophthalmologists. On average, each treated 203 patients with VEGF-inhibitors, 75.9% of which were treated with bevacizumab. Using all three agents was the most common practice (1,121 physicians), closely followed by using bevacizumab only (1,061 physicians). Ranibizumab accounted for most payments, but bevacizumab was the largest payment source for a sizeable proportion of physicians who used only/mostly bevacizumab.

CONCLUSION:

Most ophthalmologists use multiple VEGF inhibitors, but vary in their relative use. A subset of ophthalmologists predominantly use ranibizumab, but ophthalmologists overall use more bevacizumab despite financial incentives favoring ranibizumab.

Multimodal Imaging in Wagner Syndrome
Authors: Thomas Akshay S. , Branham Kari , Van Gelder Russell N. , Daiger Stephen P. , Sullivan Lori S. , Bowne Sara J. , Heckenlively John R , Pennesi Mark E.
Published: June 2016

Wagner syndrome is a rare vitreoretinopathy described in a limited number of families. Here the authors describe four cases of suspected Wagner syndrome. All four cases had depressed rod and cone function on electroretinography, outer retinal disruption on spectral-domain optical coherence tomography, and constricted central visual fields with smaller isopter testing. Fundus autofluorescence performed in one patient highlighted a perivascular pattern to chorioretinal atrophy. Two patients had a history of uveitis with active cystoid macular edema. The diagnosis of Wagner syndrome was supported in three cases with genetic testing for
VCAN
mutations, whereas the other case harbored a variation of unknown significance in
VCAN
that may have been nonpathogenic.

A Focal Chorioretinal
Bartonella
Lesion Analyzed by Optical Coherence Tomography Angiography

Neovascularization may be associated with cat-scratch neuroretinitis in the absence of retinal vascular occlusion.
Bartonella
organisms establish an intimate relationship with the vascular endothelium, causing angioproliferative lesions, which might represent a dedicated pathogenic strategy for expanding the bacterial host cell habitat. In the eye, pathological angiogenesis caused by
Bartonella
has been described as peripapillary or macular choroidal neovascularization, but the presence of neovascularization within foci of chorioretinitis has never before been reported. The authors present a case of
Bartonella
chorioretinitis in which optical coherence tomography angiography, by detecting erythrocyte motion, was able to identify neovessels inside the infectious focus.

Spectral-Domain Optical Coherence Tomography Findings in Lipemia Retinalis
Authors: Özturk Banu Turgut , Bozkurt Banu , Meşen Ali , Gonul Saban , İpekci Süleyman Hilmi
Published: June 2016

Severe hypertriglyceridemia can give rise to a fundus appearance with whitish-colored retinal vessels called lipemia retinalis. A 52-year-old man with hypertriglyceridemia presented with a best-corrected visual acuity of 20/20 in both eyes and creamy-white retinal vessels on fundus. Spectral-domain optical coherence tomography (SD-OCT) revealed hyperreflective and engorged retinal vessels and white dots mainly accumulated in the inner nuclear and ganglion cell layer. Follow-up fundus examination after plasmapheresis sessions revealed normal retinal vessels. The hyperreflective appearance of the retinal vessels in OCT reversed rapidly 5 days after the treatment, whereas hyperreflective dots in retina disappeared slowly in 3 months. OCT is useful in demonstrating inner retinal changes associated with lipemia retinalis at histopathological level. The hyperreflective dots in inner retina associated with leakage from superficial retinal capillaries attested the correlation of their location with their origin.

Macular Telangiectasia Type 1 Managed With Long-Term Aflibercept Therapy
Authors: Kovach Jaclyn L. , Hess Harald , Rosenfeld Philip J.
Published: June 2016

A 60-year-old man diagnosed with macular telangiectasia type 1 (MacTel 1) was treated for 3 years with monthly aflibercept (Eylea; Regeneron, Tarrytown, NY) and serially imaged with spectral-domain optical coherence tomography. When administered monthly, aflibercept appeared to have a beneficial effect on macular edema secondary to MacTel 1. Visual acuity preservation despite minimal chronic macular edema could be attributed to the lack of significant photoreceptor disruption.

“Female Charm”
Authors: Costa Carlos , Breda Zélia , Bakas Fiona Eva , Durão Marília , Pinho Isabel
Published: June 2016

A significant challenge faced by the tourism and hospitality industries in a rapidly changing world, is the ability to sustain organisational growth. Some of the main strategies for achieving organisational growth are those related to innovation, internationalisation and networking. Addressing tourism studies' contemporary shift to a focus on social influences, this study investigates the relations between gender and organisational growth. Qualitative analysis of focus groups with managers from the seven administrative regions in Portugal provides an in-depth account of tourism and gender issues based on empirical evidence. Viewing the ways in which tourism managers contribute to organisational growth through the angle of gender, this chapter provides a compelling account of the delicate and often invisible interactions between economic and social transactions. Results illustrate how women as a labour source are paradoxically viewed as both an asset and an impediment to organisational growth strategies.
The Role of Inquiry in Teachers' Learning from the National Board Certification Process
Authors: Coskie Tracy L. , Place Nancy A.
Published: June 2016

In this chapter the authors present a framework for teacher inquiry. Drawing on data from two multiple-year qualitative studies of National Board candidates, the authors use case study methodology and document analysis to develop an understanding of the National Board as a site for inquiry in teacher learning. Three teachers' experiences, representing a range of inquiry stances, are explored to provide an opportunity to understand important elements of inquiry in teacher learning and how the National Board certification process may (or may not) support such learning.
Examining What Elementary School Teachers Take Away from Mathematics Professional Development
Authors: Polly Drew
Published: June 2016

The process of providing effective ongoing professional development to teachers is an arduous task for educational leaders. In areas, such as mathematics, professional learning opportunities must deepen teachers' knowledge of content, pedagogy, and other skills connected to teaching. This chapter provides an examination of what teachers learned during a professional development project that was designed based off of principles for Learner-Centered Professional Development and addressed components of the Mathematical Knowledge for Teaching framework. The project included 3 half-day meetings with classroom-embedded activities completed between workshops. An inductive, thematic analysis of workshop evaluations indicated that teachers' learning related to: a) a deeper understanding of the Common Core Mathematics Standards, b) exploring mathematical tasks, and c) planning lessons that start with mathematical tasks instead of direct teaching.
Not Too Young to Lead
Authors: Pucella Tanya Judd
Published: June 2016

This chapter reviews the case for leadership development opportunities for pre-service educators so that prospective teacher leaders are willing and able to take on leadership roles once in the classroom. The chapter discusses the various curricular approaches to developing the knowledge, skills, and dispositions needed for effective teacher leadership. This chapter provides a comprehensive review of the various knowledge, skills, and dispositions that can begin to be developed during an undergraduate teacher preparation program. In addition, the chapter will examine focus areas for leadership development for teachers that may not be part of the traditional pre-service teacher preparation curriculum, including the concepts of followership, power, and influence techniques.
Mediating the Sources and Benefits of Teacher Self-Efficacy for Systemic Transformative Meaning-Making
Authors: Gallavan Nancy P.
Published: June 2016

Educating the whole child, the basis of U.S. education and the progressive education movement, is imperative for teacher candidates to understand and implement their work associated with teaching, learning, and schooling P-12 learners. Thus, educating the whole teacher candidate is essential for teacher educators to emphasize and facilitate in their work in teacher preparation to optimize candidates' knowledge, skills, and dispositions. Recognizing candidates' immediate concerns and their pre-existing conditions, teacher educators strive to build teacher capacity. Framing teacher candidates' personal growth, professional development, pedagogical expertise, and political astuteness on the four sources of self-efficacy leads to a life-long journey of critical consciousness and systemic transformative meaning-making. From this research, teacher candidates provide insights and inspirations beneficial for both teacher educators and teacher candidates to improve their practices and increase their self-efficacy evident in their educator preparation programs and future P-12 classrooms.
