The Colorblind Crowd? Founder Race and Performance in Crowdfunding
Authors: Younkin Peter , Kuppuswamy Venkat
Published: May 2017

The dearth of minority entrepreneurs has received increasing media attention but few academic analyses. In particular, the funding process creates challenges for either audit or correspondence methods, making it difficult to assess the role, or type, of discrimination influencing resource providers. We use a novel approach that combines analyses of 7,617 crowdfunding projects with an experimental design to identify whether African American men are discriminated against and whether this reflects statistical, taste-based, or unconscious bias on the part of prospective supporters. We find that African American men are significantly less likely than similar white founders to receive funding and that prospective supporters rate identical projects as lower in quality when they believe the founder is an African American male. We conclude that the reduction in perceived quality does not reflect conscious assumptions of differences in founder ability or disamenity but rather an unconscious assumption that black founders are lower quality. In two additional experiments, we identify three means of reducing this bias: through additional evidence of quality via third-party endorsements (i.e., awards, evidence of prior support), through evidence that African American founders have succeeded previously, and by removing indicators of the founder’s race.

Successful return to sports in athletes following non-operative management of acute isolated posterior cruciate ligament injuries
Authors: Agolley D. , Gabr A. , Benjamin-Laing H. , Haddad F. S.
Published: May 2017

Aims

The aim of this study was to report the outcome of the non-operative treatment of high-grade posterior cruciate ligament (PCL) injuries, particularly Hughston grade III injuries, which have not previously been described.

Patients and Methods

This was a prospective study involving 46 consecutive patients who were athletes with MRI-confirmed isolated PCL injuries presenting within four weeks of injury. All had Hughston grade II (25 athletes) or III (21 athletes) injuries. Our non-operative treatment regimen involved initial bracing, followed by an individualised rehabilitation programme determined by the symptoms and physical signs. The patients were reviewed until they had returned to sports-specific training, and were reviewed again at a mean of 5.2 years (3 to 9).

Results

The mean time to return to sports-specific training was 10.6 weeks and the mean time to return to full competitive sport was 16.4 weeks (10 to 40). A total of 42 patients (91.3%) were playing at the same or higher level of sport two years after the injury, with a mean Tegner activity score of 9 (5 to 10). At five years, 32 patients (69.5%) were playing at the same or higher level of sport, and 38 patients (82.6%) were playing at a competitive level, with a mean Tegner activity score of 9 (5 to 10).

Conclusions

Medium-term review of a series of athletes suggests that commencing the non-operative management of isolated, Hughston grade II and III PCL injuries within four weeks of injury gives excellent functional outcomes with a high proportion returning to the same or higher level of sport.

Mediolateral force distribution at the knee joint shifts across activities and is driven by tibiofemoral alignment
Authors: Kutzner I. , Bender A. , Dymke J. , Duda G. , von Roth P. , Bergmann G.
Published: May 2017

Aims

Tibiofemoral alignment is important to determine the rate of progression of osteoarthritis and implant survival after total knee arthroplasty (TKA). Normally, surgeons aim for neutral tibiofemoral alignment following TKA, but this has been questioned in recent years. The aim of this study was to evaluate whether varus or valgus alignment indeed leads to increased medial or lateral tibiofemoral forces during static and dynamic weight-bearing activities.

Patients and Methods

Tibiofemoral contact forces and moments were measured in nine patients with instrumented knee implants. Medial force ratios were analysed during nine daily activities, including activities with single-limb support (e.g. walking) and double-limb support (e.g. knee bend). Hip-knee-ankle angles in the frontal plane were analysed using full-leg coronal radiographs.

Results

The medial force ratio strongly correlated with the tibiofemoral alignment in the static condition of one-legged stance (R² = 0.88) and dynamic single-limb loading (R² = 0.59) with varus malalignment leading to increased medial force ratios of up to 88%. In contrast, the correlation between leg alignment and magnitude of medial compartment force was much less pronounced. A lateral shift of force occurred during activities with double-limb support and higher knee flexion angles.

Conclusion

The medial force ratio depends on both the tibiofemoral alignment and the nature of the activity involved. It cannot be generalised to a single value. Higher medial ratios during single-limb loading are associated with varus malalignment in TKA. The current trend towards a ‘constitutional varus’ after joint replacement, in terms of overall tibiofemoral alignment, should be considered carefully with respect to the increased medial force ratio.

Published: May 2017

Aims

Pelvic reconstruction after the resection of a tumour around the acetabulum is a challenging procedure due to the complex anatomy and biomechanics. Several pelvic endoprostheses have been introduced, but the rates of complication remain high. Our aim was to review the use of a stemmed acetabular pedestal cup in the management of these patients.

Patients and Methods

The study involved 48 patients who underwent periacetabular reconstruction using a stemmed pedestal cup (Schoellner cup; Zimmer Biomet Inc., Warsaw, Indiana) between 2000 and 2013. The indications for treatment included a primary bone tumour in 27 patients and metastatic disease in 21 patients. The mean age of the patients at the time of surgery was 52 years (16 to 83).

Results

At a median follow-up of 6.6 years (95% confidence interval 4.6 to 8.2), local control was achieved in all patients; 19 patients had died (16 of disease). Complications occurred in 19 patients (40%), of which deep infection was the most common, affecting eight patients (17%). Seven patients (15%) had a dislocation of the hip. Aseptic loosening was found in three patients (6%). Two (4%) underwent hindquarter amputation for non-oncological reasons. The risk of revision, with death being treated as a competing event, was 28% at one year, 39% at five years and 48% at ten years post-operatively. The mean Musculoskeletal Tumour Society Score at final follow-up was 71% (27% to 93%).

Conclusion

This type of reconstruction is a satisfactory option for the treatment of patients with a periacetabular tumour. There remains, however, a high rate of complication, which may be reduced by future modifications of the device such as silver coating and tripolar articulation.

Oxidised zirconium versus cobalt alloy bearing surfaces in total knee arthroplasty
Authors: Anderson F. L. , Koch C. N. , Elpers M. E. , Wright T. M. , Haas S. B. , Heyse T. J.
Published: May 2017

Aims

We sought to establish whether an oxidised zirconium (OxZr) femoral component causes less loss of polyethylene volume than a cobalt alloy (CoCr) femoral component in total knee arthroplasty.

Materials and Methods

A total of 20 retrieved tibial inserts that had articulated with OxZr components were matched with 20 inserts from CoCr articulations for patient age, body mass index, length of implantation, and revision diagnosis. Changes in dimensions of the articular surfaces were compared with those of pristine inserts using laser scanning. The differences in volume between the retrieved and pristine surfaces of the two groups were calculated and compared.

Results

The loss of polyethylene volume was 122 mm3 (standard deviation (sd) 87) in the OxZr group and 170 mm3 (sd 96) in the CoCr group (p = 0.033). The volume loss in the OxZr group was also lower in the medial (72 mm3 (sd 67) versus 92 mm3 (sd 60); p = 0.096) and lateral (49 mm3 (sd 36) versus 79 mm3 (sd 61); p = 0.096) compartments separately, but these differences were not significant.

Conclusion

Our results corroborate earlier findings from in vitro testing and visual retrieval analysis which suggest that polyethylene volume loss is lower with OxZr femoral components. Since both OxZr and CoCr are hard surfaces that would be expected to create comparable amounts of polyethylene creep, the differences in volume loss may reflect differences in the in vivo wear of these inserts.

Published: May 2017

Turismo é uma atividade econômica, relacionada ao capitalismo, caracterizada pela mercantilização de produtos e serviços. Assim, o patrimônio histórico e cultural passa a ser considerado um produto, atrativo de demandas, resultante de diferentes estratégias criadas pela atividade turística. Percebe-se que há uma estreita correlação entre o desenvolvimento do turismo de alguns dos países que mais recebem turistas e os seus patrimônios, a exemplo do que ocorre na Espanha, um dos mais visitados. Dentre as cidades mais visitadas, consagra-se Barcelona – CAT/ES, possuidora de nove patrimônios históricos e culturais reconhecidos pela UNESCO, dentre eles, sete representantes do legado do arquiteto Gaudí. Este trabalho tem como objetivo analisar resultados preliminares acerca da importância desse patrimônio histórico e cultural reconhecido pela UNESCO, em vista de sua utilização como atrativo turístico. A metodologia da pesquisa se pautou no estudo de caso, devido aos procedimentos de coleta de dados e informações, provenientes de fontes secundárias e primárias, quantitativas e qualitativas. Dentre os resultados obtidos, aponta-se a necessidade de avanços nos processos de controle da demanda, principalmente nos legados de Gaudí, contratação de profissionais ligados ao turismo, ou à história, utilizando o referido patrimônio com ética, valorizando seus significados.

Published: May 2017

A partir de uma revisão das obras: O Contrato Social (2014) e O Emílio, ou; Da Educação, do filósofo francês Jean-Jacques Rousseau; bem como de textos de pesquisadores comentadores do referido teórico, objetivamos nesse estudo apresentar e discutir o pensamento de Jean-Jacques Rousseau em relação a (01) Sociedade e (02) Educação, buscando compreender as continuidades e rupturas das ideias apresentadas na contemporaneidade. A obra de Rousseau no curso sócio-histórico teve, e ainda tem grande influência sobre as formas de observar e refletir a sociedade e a educação em âmbito inter-nacionais. De sua obra são suscitadas reflexões sobre a criança, o cidadão, a organização e relação social, entre outros temas que dialogam com a contemporaneidade, mesmo, sendo seus escritos datados do século XVIII. A atemporalidade das ideias de Jean-Jacques Rousseau são fundamentais para pesquisadores/as da educação e de outros campos do saber, sendo assim pertinente a discussão proposta neste estudo, proporcionando um diálogo inter e transdisciplinar sobre os temas apresentados.

Este Artigo discute as teorias de Paulo Freire, Luiz Carlos Cagliari, Piaget e Vygotsky, à partir de uma análise das referidas teorias, e à luz das dificuldades e deficiências que os alunos de rede pública do ensino fundamental apresentam em relação a leitura e a escrita. Entende-se aqui, que a leitura é um processo que envolve outras habilidades além da decodificação. A leitura é um processo linguístico que acompanha o desenvolvimento da própria linguística seguindo o processo ascendente, descendente e interativo. Pode-se dizer que o significado que uma leitura tem para o leitor, é uma tradução do significado que o autor quis lhe dar, mais uma construção que envolve o texto, os conhecimentos prévios de leitura, que o aborda e seus objetivos, de acordo com os pensadores o ensino da língua portuguesa deve desenvolver no aluno a capacidade de compreender o texto como uma atividade necessária ao universo da vida social e escolar estabelecendo relação entre leitura de códigos e leitura de mundo. Para reverter o quadro apresentado do baixo índice de aprendizagem em relação aos estudos realizados, o professor deve ser um mediador que desenvolva no educando o senso crítico e sua maturidade respeitando a individualidade e a necessidade da realidade de cada um em relação ao ritmo de aprendizagem traçando caminhos que leve o educando a ser livre de preconceitos, respeitando as diversidades étnicas e variedades linguísticas. Entende-se que não desenvolvendo bons leitores, limitando-se as possibilidades de leitura de mundo quanto a realidade social. Constatou-se que a sociedade carece de profissionais competentes e compromissados que desenvolvam suas competências e habilidades, na consciência do seu papel como agentes transformadores da sociedade.

Divergent Students, Disruptive Students: Gender Anxieties in U.S. K–12 Schools
Authors: McLaughlin Grace
Published: May 2017

This article analyzes the operative fears informing protests of gender non-conforming K-12 students’ challenges to school bathroom, locker room, and dress code policies in the United States. It argues that anxieties raised by parents, administrators, and commentators can be understood not just as transphobic, but as mobilizing rhetoric centered on fears for the child or children as a vulnerable social category and proteophobia, or fear of the ambiguous, uncategorizable, and changing. In light of this language, and of the youth of K-12 gender nonconforming students, dress code battles specifically may allow T/GNC advocates to further a conception of gender not just as an identity, but as an expressive practice of self-fashioning or exploration.
Long-Distance Movement of a Female Polar Bear from Canada to Russia
Authors: Johnson Amy C. , Pongracz Jodie D. , Derocher Andrew E.
Published: May 2017

Polar bears (Ursus maritimus) display fidelity to large geographic regions, and their movements are influenced by sea ice distribution. Polar bear subpopulations are moderately distinct from one another, and long-distance movements between subpopulations are rare. We describe and analyze the movements of a female polar bear tracked by satellite telemetry from spring 2009 for 798 days. This female traveled an exceptionally long distance (totaling 11 686 km) from the sea ice off the Yukon Territory, Canada (Southern Beaufort Sea subpopulation) to Wrangel Island, Russia (Chukchi Sea subpopulation). In comparison to other polar bears in this study, this bear traveled farther, moved faster, and had a much larger home range in the first year. Furthermore, the calculation of the home range size by two different methods demonstrated that the commonly used minimum convex polygon method overestimated the home range compared to the less biased Brownian bridge movement model. This female’s long-distance movement was unusual and provides additional evidence for gene flow between subpopulations. Monitoring polar bear movements is useful to track such events, which is especially important at present because sea ice loss due to climate change can affect subpopulation boundaries and influence management.

Published: May 2017

Some coastal communities in western Alaska have observed the occurrence of “slush-ice berms.” These features typically form during freeze-up, when ice crystal – laden water accumulates in piles on the shore. Slush-ice berms can protect towns from storm surge, and they can limit access to the water. Local observations from the communities of Gambell, Shaktoolik, Shishmaref, and Wales were synthesized to develop a taxonomy of slush-ice berm types and a conceptual process model that describes how they form and decay. Results indicated two types of slush-ice berm formation processes: in situ (forming in place) and advective (pushed in by storm winds). Several formation mechanisms were noted for the crystals that compose in situ berms. Cold air temperatures cool the surface of the water, and winds that translate surface cooling through a greater depth aid crystal formation. Snow landing in the water cools via melting of the snow and by contributing crystals directly to the water. A negative surge can expose the wet beach to cold air, allowing crystals to form on the beach, which are then picked up by waves. Slush crystals for advective berm events form offshore. Winds move the slush towards shore, where it accumulates, and wind-induced waves move it up onto the beach.

Published: May 2017

Schools as educational institutions bringing children for community are very effective for gaining values. The fundamental goal of schools is to nurture academically successful individuals adopted with basic values. Values are understandings that are sources of behaviors and used to judge them. Schools should work gaining of these basic values through practices by giving place to conscious implementations for gaining of values like tolerance, being fair, sharing, cooperation, being reliable, etc. Activation of values in learning-teaching environment contributes to social and emotional developments of children. For effective learning-teaching environment in gaining values, teachers' consideration of acquisition and accumulation related to values is significant. This study is performed with the purpose of exploring views of principals, teachers, students and parents about the values that teachers should have. Working group of the study includes 5 school principals, 30 teachers, 112 students (9th, 10th, 11th grades) and 50 parents within 2 high schools in the city center of Eskişehir. As a data collection tool, four different question forms are prepared for administrators, teachers, students and parents. Qualitative research method was used. According to analysis esults, 5 themes are reached depending on administrators views. With highest frequency, administrators indicated that teachers should have values as being selfless and tolerate. Teachers expressed their point of views that the most essential value teachers should have is guidance and the least necessary value is use of language. According to students' views, communication ability has the highest frequency as a basic value that teachers should have. Parents give more value to Professional qualifications of teachers. The findings are interpreted in the light of relevant literature.

Published: May 2017

Aluminium matrix material reinforced with particulates constitutes a material matrix composite with low wear rate and substantial hardness, owing to which it has marked its path in many engineering applications. The sub-sequential design and selection of new variants of composites can be done to improve its tribological performance. In the present work, the wear behaviour of aluminium metal matrix composites (AA7075 as matrix material and titanium carbide (TiC) particulates as reinforced material) fabricated through stir casting method was studied. The wear rate was investigated on a pin-on-disc machine and analysis of variance was used to identify the effect of control parameters such as sliding velocity, sliding distance and wt.% of reinforcement on the volumetric wear rate at a fixed load of 20 N. The hardness and wear resistance of the composites were found to be strengthened with the TiC particles reinforced into the AA7075 matrix material. Results show that volumetric wear rate decreases with increasing sliding velocity but increases with increasing sliding distance, irrespective of the wt.% of TiC particles added to composites. Confirmation tests were carried out to verify the experimental results and the worn-out surfaces of selected samples were analysed with scanning electron microscopy
A study on the damage evolution of P91 steel under cyclic loading at high temperature
Authors: Saad A.A. , Bachok Z. , Sun W.
Published: May 2017

This study aimed to investigate the effect of cyclic loading on structural integrity of a P91 specimen at high temperature. The experiments were conducted using a thermomechanical fatigue test machine at 600 °C and electron microscopy investigation. The evolution of the elastic modulus can be used as an indication of the strength degradation of the material. Scanning and transmission electron microscopy were used to investigate the microstructural variations that occurred in the specimen at different life fractions during the cyclic tests. Based on the experimental stress–strain data, variations in the Young’s modulus and the area enclosed in the hysteresis loops were determined, together with the variations in other parameters throughout the test. The initiation of cracks begins in the second stage of cyclic softening. The changes of structure, on a micro-scale, do not significantly affect the strength of the specimen, as the Young’s modulus values of the specimen remain approximately constant up to the end of the stage 2 cyclic softening before damage to the specimen starts to increase. The cracks cause the material to become weaker, as indicated by the decrease of the Young’s modulus value. The evolution of damage was found to be significant in the final stages of softening owing to the propagation of cracks in the P91 steel affecting the integrity of the material.

This paper investigates the fatigue damage behaviour of random service loading histories and suggests a criterion to determine fatigue damaging cycles by using probability values. The rainflow strain range distribution is often used in fatigue damage prediction. The existence of very small amplitude of cycles that do not significantly contribute to damage makes the prediction process unnecessarily complex. Therefore, a criterion to determine the size of damaging cycles that contribute significantly to total damage values is desired. In this study, two datasets were compared, i.e. the standard SAE road profile for the suspension system and an experimental data recorded using a strain gauge installed on a vehicle component. Fatigue damage was determined using the Coffin–Manson, Morrow and Smith–Watson–Topper models. The distribution of strain ranges was identified by distribution fitting process. The relation between strain range magnitude and RMS values was explored using the probability of damage occurrence values. The results show that both sets of strain histories data fit well to a mixed Weibull distribution with n subpopulations. The probability of damage occurrence values obtained were very high, i.e. 0.9362 and 0.9987, indicating very high chances of damage incurred by these damaging cycles. Therefore, 2 RMS values is suggested as a criterion for damaging cycles determination.

USP9X (ubiquitin-specific peptidase 9, X chromosome) is the mammalian orthologue ofDrosophiladeubiquitinase fat facets that was previously shown to regulate the maintenance of the germ cell lineage partially through stabilizing Vasa, one of the widely conserved factors crucial for gametogenesis. Here, we demonstrate that USP9X is expressed in the gonocytes and spermatogonia in mouse testes from newborn to adult stages. By usingVasa-Cremice, germ cell-specific conditional deletion ofUsp9xfrom the embryonic stage showed no abnormality in the developing testes by 1 week and no appreciable defects in the undifferentiated and differentiating spermatogonia at postnatal and adult stages. Interestingly, after 2 weeks,Usp9x-null spermatogenic cells underwent apoptotic cell death at the early spermatocyte stage, and then, caused subsequent aberrant spermiogenesis, which resulted in a complete infertility ofUsp9xconditional knockout male mice. These data provide the first evidence of the crucial role of the spermatogonial USP9X during transition from the mitotic to meiotic phases and/or maintenance of early meiotic phase inUsp9xconditional knockout testes.

Background & Aims: Liver stiffness (LS) measurement by Transient Elastography (TE) has been widely accepted as a tool for fibrosis assessment. The aim of this study was to assess LS dynamics in a group of patients with HCV liver cirrhosis after interferon free treatment (IFT).Methods: This two-center clinical trial included 225 patients with compensated HCV cirrhosis (all genotype 1b), who received IFT for 12 weeks. All patients were evaluated by means of TE at the beginning and at the end of treatment (EOT), and a subgroup (170 patients) also 12 weeks after EOT; all of them had sustained viral response (SVR). Reliable LS measurements (LSM) were defined as a median value of 10 valid LSM, with IQR <30% and SR ≥60%. Both M and XL probes were used. For diagnosing cirrhosis we used a cut-off value of 12kPa as proposed by the Tsochatzis meta-analysis. We considered a decrease or increase of more than 10% in LSM as being significant.Results: Out of 225 subjects, reliable measurements were obtained in 93.7%, so that the final analysis included 211 patients. The mean LS values decreased significantly after IFT: 26.4±11.7 vs. 23.5±13.3 kPa (p=0.01). Most patients, 59.2% (125/211) presented more than 10% decrease in LS values, 24.1% (51/211) had stable LS values, while in 16.4% (35/211) cases, the LS values increased. In the subgroup of 170 patients with LSM also performed 12 weeks after EOT (SVR), the mean LS values were significantly lower as compared to baseline: 21.3±11 kPa vs. 27.4±11.9 kPa (p<0.0001) and also as compared to EOT: 21.3±11 kPa vs. 23.7±13.3 kPa (p<0.0001).Conclusion: In our patients with HCV liver cirrhosis, the mean LS values evaluated by TE significantly decreased after antiviral treatment at EOT and also 12 weeks after EOT as compared to baseline. Overall, about 60% of patients had LS values at EOT lower than at baseline, while 12 weeks after EOT about 75% of patients had LS values lower than at baseline. –.Abbreviations: APRI: aspartate aminotransferase platelet ratio index; BMI: body mass index; DAA: direct acting agents; EOT: end of treatment; FIB-4: fibrosis 4; HBV: hepatitis B virus; HCV: hepatitis C virus; IFT: interferon free treatment; IQR: interquartile range; LS: liver stiffness; LSM: liver stiffness measurements; SR: success rate; SVR: sustained viral response; TE: Transient Elastography.

Narrativas das mulheres das classes populares: modos de subjetivação e educação escolar
Authors: Ferrari Anderson , Mattos Zaine Simas
Published: May 2017

Este texto é resultado de uma pesquisa que tem como foco de análise os atravessamentos de classe e gênero nos modos de subjetivação de mulheres das classes populares. O campo de investigação é uma escola pública municipal que atendia e atende mulheres das classes populares, de maneira que foi possível trabalhar com duas gerações de famílias chefiadas por mulheres. Trabalhando com entrevistas narrativas, a pesquisa tem como foco os relatos que ressaltam as vivências delas nos modos de serem mulheres, mães, ex-alunas, representantes das classes populares e de gerações distintas no que tange às suas relações com a educação escolar. Para isso, assumiu-se uma questão motivadora, que se buscou responder neste texto: de que modos as mulheres narram as suas relações com a educaçãoescolar e como essas relações são atravessadas por classe e gênero? Este, o referencial teórico-metodológico do qual este artigo se aproxima, privilegiando os estudos foucaultianos por um viés pós-estruturalista.

A docência nas séries iniciais do ensino fundamental: reflexões sobre a escolha da profissão e sobre o exercício profissional
Authors: Pontes Ana Paula Furtado Soares
Published: May 2017

Este artigo discute a iniciação à docência e os dilemas do exercício profissional na visão dos professores das séries iniciais do ensino fundamental de escolas estaduais da Paraíba, onde desenvolve-se um projeto de extensão. A pesquisa, de cunho qualitativo (ALVES-MAZZOTTI, 2002), foi desenvolvida em três escolas públicas, localizadas em João Pessoa, a partir de entrevistas com 11 professores. O artigo traz uma breve discussão acerca da docência como profissão, seguida da análise dos resultados em termos de caracterização dos professores entrevistados, escolha da profissão e exercício profissional. As conclusões avançam no sentido de se compreender que a docência tem perdido conquistas profissionais históricas, chamando-se a atenção para o desafio do resgate da valorização da colegialidade docente e para o fortalecimento da relação entre os pares (IMBERNÓN, 2000) como estratégia importante no fortalecimento da docência como profissão.
