Authors: Yuan Renmin , Luo Tao , Sun Jianning , Liu Hao , Fu Yunfei , Wang Zhien
Published: April 2016

Abstract. Atmospheric aerosol greatly influences human health and the natural environment, as well as the weather and climate system. Therefore, atmospheric aerosol has attracted significant attention from society. Despite consistent research efforts, there are still uncertainties in understanding its effects due to poor knowledge about aerosol vertical transport caused by the limited measurement capabilities of aerosol mass vertical transport flux. In this paper, a new method for measuring atmospheric aerosol vertical transport flux is developed based on the similarity theory of surface layer, the theory of light propagation in a turbulent atmosphere, and the observations and studies of the atmospheric equivalent refractive index (AERI). The results show that aerosol mass flux can be linked to the real and imaginary parts of the atmospheric equivalent refractive index structure parameter (AERISP) and the ratio of aerosol mass concentration to the imaginary part of the AERI. The real and imaginary parts of the AERISP can be measured based on the light-propagation theory. The ratio of the aerosol mass concentration to the imaginary part of the AERI can be measured based on the measurements of aerosol mass concentration and visibility. The observational results show that aerosol vertical transport flux varies diurnally and is related to the aerosol spatial distribution. The maximum aerosol flux during the experimental period in Hefei City was 0.017 mg m−2 s−1, and the mean value was 0.004 mg m−2 s−1. The new method offers an effective way to study aerosol vertical transport in complex environments.
Water mass characteristics and their temporal changes in a biological hotspot in the southern Chukchi Sea

Published: April 2016

Abstract. We analysed mooring and ship-based hydrographic and biogeochemical data obtained from a Hope Valley biological hotspot in the southern Chukchi Sea. The moorings were deployed from 16 July 2012 to 19 July 2014, and data were captured during spring and autumn blooms with high chlorophyll a concentrations. Turbidity increased and dissolved oxygen decreased in the bottom water at the mooring site before the autumn bloom, suggesting an accumulation of particulate organic matter and its decomposition (nutrient regeneration) at the bottom. This event may have been a trigger for the autumn bloom at this site. The bloom was maintained for 1 month in 2012 and for 2 months in 2013. The maintenance mechanism for the autumn bloom was also studied by hydrographic and biogeochemical surveys in late summer to autumn 2012 and 2013. Nutrient-rich water from the Bering Sea supplied nutrients to Hope Valley, although a reduction in nutrients occurred in 2012 by the influence of lower-nutrient water that would have remained on the Chukchi Sea shelf. In addition, nutrient regeneration at the bottom of Hope Valley could have increased nutrient concentrations and explained 60 % of its nutrient content in the bottom water in the autumn of 2012. The high nutrient content with the dome-like structure of the bottom water may have maintained the high primary productivity via the vertical nutrient supply from the bottom water, which was likely caused by wind-induced mixing during the autumn bloom. Primary productivity was 0.3 g C m−2 d−1 in September 2012 and 1.6 g C m−2 d−1 in September 2013. The lower productivity in 2012 was related to strong stratification caused by the high fraction of surface sea ice meltwater.

Published: April 2016

Abstract. During the last decade there has been considerable development in remote sensing techniques relating to soil moisture retrievals over large areas. Within the framework of the European Space Agency's (ESA) Climate Change Initiative (CCI) a new soil moisture product has been generated, merging different satellite-based surface soil moisture based products. Such remotely sensed data need to be validated by means of in situ observations in different climatic regions. In that context, a comprehensive, distributed network of in situ measurement stations gathering information on soil moisture, as well as soil temperature, has been set up in recent years at the Finnish Meteorological Institute's (FMI) Sodankylä Arctic research station. The network forms a calibration and validation (CAL–VAL) reference site and is used as a tool to evaluate the validity of satellite retrievals of soil properties. In this paper we present the Sodankylä CAL–VAL reference site soil moisture observation network, its instrumentation as well as its areal representativeness over the study area and the region in general as a whole. As an example of data utilization, comparisons of spatially weighted average top-layer soil moisture observations between the years 2012 and 2014 against ESA CCI soil moisture data product estimates are presented and discussed. The comparisons were made against a single ESA CCI data product pixel encapsulating most of the Sodankylä CAL–VAL network sites. Comparisons are made with daily averaged and running weekly averaged soil moisture data as well as through application of an exponential soil moisture filter. The overall achieved correlation between the ESA CCI data product and in situ observations varies considerably (from 0.479 to 0.637) depending on the applied comparison perspective. Similarly, depending on the comparison perspective used, inter-annual correlation comparison results exhibit even more pronounced variation, ranging from 0.166 to 0.840.

A Comparative Study of the Impact of Metalinguistic Feedback and Explicit Correction on the Writing Performance of Iranian EFL Learners
Authors: Khah Yazdan Azizi , Farahian Majid
Published: April 2016

The present study aimed at investigating the impact of two different strategies of providing written corrective feedback on English as foreign language (EFL) learners’ writing performance. To achieve this goal, sixty EFL learners who participated in the study were assigned into two groups. Throughout the period of the study, two techniques of written feedback, metalinguistic feedback and explicit correction feedback were put into practice as the treatment. The first writing assignment was used as the pretest and the last writing assignment was the posttest. To determine the proficiency level of the participants, A Nelson English Proficiency Test was used. The result of the paired t-tests showed that the writing performance of two groups improved; however, the independent t-test was performed between the posttests of the two groups indicated that the group with metalinguistic feedback had greater improvement than the group which received the explicit correction feedback. The findings suggest that providing teacher corrective feedback is effective in reducing EFL learners’ grammatical errors and improves their writing achievement.
Pontos comuns e heterogeneidade das culturas políticas nos PALOPs
Authors: Cahen Michel
Published: April 2016

Nas interpretações da evolução dos PALOPs, muitas vezes o que foi feito, em particular por académicos de esquerda, corresponde exatamente ao que os autores pioneiros dos estudos subalternos na Índia censuravam aos autores próximos do nacionalismo modernista do Partido do Congresso ou do marxismo estalinizado do Partido comunista da Índia: a saber, uma hipertrofia do papel dos discursos, do papel das elites em via de globalização e uma desvalorização das expressões das subalternidades. Além disso, se muitos artigos, teses, e livros em ciências sociais sobre e nos países de língua portuguesa incluíram frequentemente nos seus títulos a palavra “pós(-)colonial” a partir dos finais do século xx, na grande maioria dos casos, o sentido foi meramente cronológico (“pós-colonial”), sem ligação com uma aproximação teórica “póscolonial”. Mas também se deve evitar a essencialização da herança colonial trazida pela teoria póscolonial, que subestima os processos contemporâneos de produção da subalternidade, sem os quais essas heranças coloniais perderiam rapidamente a sua relevância em certos estratos sociais. Neste contexto, o objetivo deste artigo é desenvolver uma análise subalternista mas “pós-póscolonial” da evolução dos PALOPs, relativizando o papel do discurso político das elites no poder, para dar prioridade à evolução das formações sociais, e, neste quadro, voltar a analisar o “conteúdo social” da cultura política manifestada pelo discurso. Além disso, é necessário considerar a grande diversidade dos PALOPs, que são países bem mais inseridos na história das suas regiões respectivas do que “ex-portugueses”.
OS IMPOSTOS E OS DIREITOS HUMANOS: A IMUNIDADE TRIBUTÁRIA RELIGIOSA COMO POTENCIAL INCENTIVO ECONÔMICO À HOMOFOBIA
Authors: Pinheiro Douglas Antônio Rocha
Published: April 2016

O presente texto é fruto de uma pesquisa interdisciplinar maior que investiga se (e como) os estudos econômicos podem dar suporte a demandas por direitos humanos. Este artigo, em particular, busca verificar se a imunidade tributária religiosa, garantida pela Constituição Federal aos templos de qualquer culto, gera vantagens competitivas para as igrejas nas disputas que as mesmas travam com as entidades de defesa de direitos LGBT na esfera pública. Para atingir tal objetivo, o artigo faz uma pesquisa bibliográfica sobre a amplitude jurídica de tal imunidade, à luz da interpretação feita pelo Supremo Tribunal Federal, assim como sobre seu impacto no próprio mercado religioso e no mercado da opinião pública – especialmente em relação aos debates que versam sobre orientação sexual e identidade de gênero. Por fim, o texto defende a extensão da imunidade tributária às entidades defensoras de direitos LGBT como forma de corrigir uma falha do mercado da opinião pública e de evitar um incentivo econômico à homofobia.

Weblogs as Tools for Encouraging Self-Reflection and Peer Feedback among Student Teachers
Authors: AL-Ajmi Sarah A.
Published: April 2016

A weblog is one of the most effective tools among the latest inventions that enhance student teachers’ learning and practice. With technology becoming crucial for both personal and professional developments, this study focused on the effectiveness of using reflective weblogs in teacher education programs. In this regard, the research investigated the level to which weblogs successfully promote self-reflection and yield peer feedback among student teachers. Furthermore, it explored student teachers’ perceptions regarding the use of weblogs as tools for self-reflection and peer feedback.

A case study of seven EFL student teachers taking a practicum course at Kuwait University was analyzed in this paper. The study was conducted in the English Curricula and Teaching Methods Department in the College of Education during the first semester of the 2013/2014 academic year. During the 4-week application period, participants were requested to reflect on their teaching practices and provide feedback on their peers’ posts. The data were collected through different qualitative methods such as semi-structured interviews and content analysis.

The findings of the study suggest that the use of the practicum blog is considered to be effective in facilitating student teachers’ ability to reflect upon their teaching practices and provide comments on their peers during the practicum course. Most participants agree on the usefulness of using weblogs in teacher education programs. Overall, the study results show that student teachers find the weblog as an effective tool for writing reflections, sharing ideas, providing feedbacks, and increasing proficiency levels. The results of the study provide the rationale for using weblogs in student teacher education programs.

Liposclerosing Myxofibrous Tumor: A Review
Authors: Deel Chelsey , Hassell Lewis
Published: April 2016

Liposclerosing myxofibrous tumor is a benign fibro-osseous lesion, with distinct radiographic and clinical features and diverse histologic patterns. This lesion occurs in the fourth decade of life, with equal male and female incidence. Most lesions are discovered incidentally, but patients can present with bone pain or fracture. Liposclerosing myxofibrous tumor exhibits a very strong predilection for the proximal femur with characteristic radiographic findings, often providing an initial clue to diagnosis. Microscopically, this tumor is characterized by a variety of patterns, including myxofibrous tissue, fibrous dysplasia–like features, and ischemic ossification. It can be mistaken for many other fibro-osseous lesions; therefore, this unique lesion should be included in the differential diagnosis of fibro-osseous lesions, particularly in this location. Patients with this lesion are generally successfully treated by curettage and bone graft and have a favorable prognosis. A small risk of malignant transformation has been suggested to be associated with these lesions. This necessitates the need for follow-up monitoring of this entity. In this review, we discuss current knowledge of this lesion and its clinical relevance.

Authors: Lee Hwajeong , Westerhoff Maria , Shen Bo , Liu Xiuli
Published: April 2016

Context.—Idiopathic inflammatory bowel disease manifests with different clinical phenotypes showing varying behavior and risk for neoplasia. The clinical questions that are posed to pathologists differ depending on phase of the disease and the clinical circumstances. Understanding the clinical aspects of the dynamic disease process will enhance the role of pathology in optimizing the care of patients with inflammatory bowel disease.

Objective.—To review clinical and surgical aspects of inflammatory bowel disease that are relevant to practicing pathologists.

Data Sources.—The literature was reviewed.

Conclusions.—Diagnosis and management of inflammatory bowel disease require an integrated evaluation of clinical, endoscopic, radiologic, and pathologic features. Therefore, close interaction between clinicians and pathologists is crucial. Having this team approach improves understanding of the pertinent clinical and surgical aspects of the disease and assists in the recognition of unusual presentation of variants, as well as mimics of idiopathic inflammatory bowel disease, by pathologists.
Recent Updates on Neuroendocrine Tumors From the Gastrointestinal and Pancreatobiliary Tracts
Authors: Kim Joo Young , Hong Seung-Mo
Published: April 2016

Context.—Gastrointestinal (GI) and pancreatobiliary tracts contain a variety of neuroendocrine cells that constitute a diffuse endocrine system. Neuroendocrine tumors (NETs) from these organs are heterogeneous tumors with diverse clinical behaviors. Recent improvements in the understanding of NETs from the GI and pancreatobiliary tracts have led to more-refined definitions of the clinicopathologic characteristics of these tumors. Under the 2010 World Health Organization classification scheme, NETs are classified as grade (G) 1 NETs, G2 NETs, neuroendocrine carcinomas, and mixed adenoneuroendocrine carcinomas. Histologic grades are dependent on mitotic counts and the Ki-67 labeling index. Several new issues arose after implementation of the 2010 World Health Organization classification scheme, such as issues with well-differentiated NETs with G3 Ki-67 labeling index and the evaluation of mitotic counts and Ki-67 labeling. Hereditary syndromes, including multiple endocrine neoplasia type 1 syndrome, von Hippel-Lindau syndrome, neurofibromatosis 1, and tuberous sclerosis, are related to NETs of the GI and pancreatobiliary tracts. Several prognostic markers of GI and pancreatobiliary tract NETs have been introduced, but many of them require further validation.

Objective.—To understand clinicopathologic characteristics of NETs from the GI and pancreatobiliary tracts.

Data Sources.—PubMed (US National Library of Medicine) reports were reviewed.

Conclusions.—In this review, we briefly summarize recent developments and issues related to NETs of the GI and pancreatobiliary tracts.

The BIR 2015 workshops captured important and novel topics on information logistics and knowledge supply, security and compliance in business processes, and use of ontologies in information systems. Within this context the fifth publication included in this issue complements the topic of the business informatics research with the investigation of a model-driven approach on the gesture-based interaction in information systems.
GestUI: A Model-driven Method and Tool for Including Gesture-based Interaction in User Interfaces
Authors: Parra Otto , España Sergio , Pastor Oscar
Published: April 2016

Among the technological advances in touch-based devices, gesture-based interaction have become a prevalent feature in many application domains. Information systems are starting to explore this type of interaction. As a result, gesture specifications are now being hard-coded by developers at the source code level that hinders their reusability and portability. Similarly, defining new gestures that reflect user requirements is a complex process. This paper describes a model-driven approach to include gesture-based interaction in desktop information systems. It incorporates a tool prototype that captures user-sketched multi-stroke gestures and transforms them into a model by automatically generating the gesture catalogue for gesture-based interaction technologies and gesture-based user interface source codes. We demonstrated our approach in several applications ranging from case tools to form-based information systems.
The functional O-mannose glycan on α-dystroglycan contains a phospho-ribitol primed for matriglycan addition

Published: April 2016

Multiple glycosyltransferases are essential for the proper modification of alpha-dystroglycan, as mutations in the encoding genes cause congenital/limb-girdle muscular dystrophies. Here we elucidate further the structure of anO-mannose-initiated glycan on alpha-dystroglycan that is required to generate its extracellular matrix-binding polysaccharide. This functional glycan contains a novel ribitol structure that links a phosphotrisaccharide to xylose. ISPD is a CDP-ribitol (ribose) pyrophosphorylase that generates the reduced sugar nucleotide for the insertion of ribitol in a phosphodiester linkage to the glycoprotein. TMEM5 is a UDP-xylosyl transferase that elaborates the structure. We demonstrate in a zebrafish model as well as in a human patient that defects in TMEM5 result in muscular dystrophy in combination with abnormal brain development. Thus, we propose a novel structure—a ribitol in a phosphodiester linkage—for the moiety on which TMEM5, B4GAT1, and LARGE act to generate the functional receptor for ECM proteins having LG domains.
Hysterosalpingo‐Contrast Sonography With a Saline‐Air Device Is Equivalent to Hysterosalpingography Only in the Presence of Tubal Patency
Authors: Robertshaw Isela M. , Sroga Julie M. , Batcheller April E. , Martinez Alan M. , Winter Thomas C. , Sinning Kristin , Maxwell Rose , Lindheim Steven R.
Published: April 2016

Objectives

To compare hysterosalpingo‐contrast sonography with a saline‐air device to hysterosalpingography for evaluating tubal patency.

Methods

Eighty women undergoing infertility evaluations were recruited for this prospective cohort study. All patients underwent both office‐based hysterosalpingo‐contrast sonography with a saline‐air device and hysterosalpingography as the reference standard, and the fallopian tubes were individually assessed for tubal patency in each procedure. The Cohen κ coefficient was used to assess agreement between each procedure, and the Student t test and χ2 test were used to compare differences in time, pain, and procedural preference.

Results

In total, 75 patients with 148 fallopian tubes were evaluated. Tubal patency on hysterosalpingo‐contrast sonography with the saline‐air device was noted in 85.8% (n = 127) of tubes compared to 92.5% (n = 137) on hysterosalpingography, with a positive predictive value of 95.2%. Tubal occlusion was noted in 21 tubes (14.2%) on hysterosalpingo‐contrast sonography compared to 11 (7.4%) on hysterosalpingography, with a negative predictive value of 23.8% (24 of 28). Overall, hysterosalpingo‐contrast sonography agreed with hysterosalpingography in 126 of 148 fallopian tubes (85.1%; κ = 0.47; P < .001). The procedural time and pain scores were significantly greater for hysterosalpingo‐contrast sonography compared to hysterosalpingography.

Conclusions

There was a significant degree of agreement between hysterosalpingo‐contrast sonography with a saline‐air device and hysterosalpingography when the fallopian tube was patent but not when it was occluded. In the absence of patency, further evaluations with hysterosalpingography may be indicated to avoid false‐positive results. Although the procedure time and degree of pain appear to be greater, avoidance of radiation exposure by using hysterosalpingo‐contrast sonography with a saline‐air device may outweigh the drawbacks.

Published: April 2016

Pumpkin has been employed for the first time as a renewable, low‐cost precursor for the preparation of porous carbon materials with excellent performance. Unlike most other precursors, pumpkin is rich in sugars and starch, and it has advantageous properties for large‐scale production. The as‐prepared materials adopted a unique morphology that consisted of numerous fused sphere‐like carbon grains with a high specific surface area (2968 m2 g−1), abundant micro and mesopores, and excellent electrochemical properties. The pumpkin‐derived activated carbon (PAC) material not only exhibited a high specific capacitance of 419 F g−1, but also showed considerable cycling stability, with 93.6 % retention after 10 000 cycles. Moreover, a symmetrical supercapacitor that was based on PAC showed a high energy density of 22.1 W h kg−1 in aqueous electrolyte. These superior properties demonstrate that PAC holds great promise for applications in electrochemical energy‐storage devices.
