Effect of phosphorus on nitrogen migration and transformation in deep subsurface wastewater infiltration systems
Authors: Wang Hongqiang , Zhang Lieyu 
Published: September 2017

Abstract
This paper investigates the effect of phosphorus on nitrogen migration and transformation during the sewage purification processes in deep subsurface wastewater infiltration systems. Good performance was achieved with a hydraulic loading rate of 0.1 m3/m2·d, indicating that the effluent water quality could meet the primary grade A values as put forth by the ‘Cities Sewage Treatment Plant Pollutant Discharge Standard’ (GB18918-2002). In addition, the results of three inflow total phosphorus (TP) concentrations (5 mg L−1, 15 mg L−1, and 30 mg L−1) indicated that high-levels of phosphorus were more advantageous in regards to improving the activity of denitrifying bacteria in soil and strengthening the effect of nitrogen removal, suggesting that the effluent total nitrogen (TN) concentration could meet the primary grade A standard (TN ≤ 15 mg L−1). It was further observed that soil depth was less crucial when inflow TP concentrations were higher. Therefore, the results indicated that inflow phosphorus concentrations could greatly influence nitrogen migration and transformation in deep subsurface wastewater infiltration systems.
An Instructor Learning Analytics Implementation Model
Authors: McKee Holly 
Published: September 2017

With the widespread use of learning analytics tools, there is a need to explore how these technologies can be used to enhance teaching and learning. Little research has been conducted on what human processes are necessary to facilitate meaningful adoption of learning analytics. The research problem is that there is a lack of evidence-based guidance on how instructors can effectively implement learning analytics to support students with the purpose of improving learning outcomes. The goal was to develop and validate a model to guide instructors in the implementation of learning analytics tools. Using design and development research methods, an implementation model was constructed and validated internally. Themes emerged falling into the categories of adoption and caution with six themes falling under adoption including: LA as evidence, reaching out, frequency, early identification/intervention, self-reflection, and align LA with pedagogical intent and three themes falling under the category of caution including: skepticism, fear of overdependence, and question of usefulness. The model should enhance instructors’ use of learning analytics by enabling them to better take advantage of available technologies to support teaching and learning in online and blended learning environments. Researchers can further validate the model by studying its usability (i.e., usefulness, effectiveness, efficiency, and learnability), as well as, how instructors’ use of this model to implement learning analytics in their courses affects retention, persistence, and performance.

With a goal of improving the development and delivery of effective online information literacy resources, the purpose of this study was to look at how program level and the timing of the introduction of a Literature Review library guide influenced online business student perceived value of the resource. A population of undergraduate business students (N=355) and online MBA students (N=319) were introduced to a Literature Review library guide during specific points in their programs. Students were asked to complete an online survey that included 17 closed-ended items designed to measure perceived usefulness, satisfaction and likeliness to use the guide again. The survey also included two open-ended questions asking students to discuss those elements of the guide they found most valuable and whether any features had not been included in the guide, but which they would have liked to see. The data collection strategy required faculty post information about the Literature Review library guide and the survey in their courses at two specified times in the course. A low response rate (3.5%) resulted from inconsistencies in faculty including information about the guide and study in their courses. Although the small sample size (n=24) limited the planned analysis and resulted in no statistical significance between groups, descriptive findings were reported, and trends were used to revise the resource and inform future development of library research guides. Overall, students reported being satisfied with the resource and found it usable. Graduate students were more likely to report elements of the guide that supported effective search and evaluation strategies were valuable; whereas, undergraduate students tended to value the links to writing resources. Student feedback also suggested that the earlier the guide was introduced in the program, the more likely students would use the resource. Adopting a model that embeds resource guides early, and aligning guide content with the curriculum should lead to increased use of the resource.
Analisa Perbandingan Quality of Service Voice Over IP dengan Pengujian Codec Menggunakan Algoritma Low Latency Queuing
Authors: Darmawan Darmawan , Syafriyatno Yayan 
Published: September 2017

Voice over IP (VoIP) adalah solusi komunikasi suara yang murah karena menggunakan jaringan IP dibanding penggunaan telephone analog yang banyak memakan biaya. Dalam penerapannya, VoIP mengalami permasalahan karena menggunakan teknologi packet switching yang mana penggunaannya bersamaan dengan paket data sehingga timbul delay, jitter, dan packet loss. Pada penelitian ini, algoritma Low Latency Queuing (LLQ) diterapkan pada router cisco. Algoritma LLQ merupakan gabungan dari algoritma Priority Queuing (PQ) dan Class Based Weight Fair Queuing (CBWFQ) sehingga dapat memprioritaskan paket suara disamping paket data. Algoritma LLQ ini diujikan menggunakan codec GSM FR, G722, dan G711 A-law. Hasil pengujian didapatkan nilai parameter yang tidak jauh berbeda dan memenuhi standar ITU-T.G1010. Nilai delay rata - rata terendah yaitu ketika menggunakan codec G722 sebesar 20,019 ms tetapi G722 memiliki rata - rata jitter yang terbesar yaitu 0,986 ms. Codec dengan jitter rata – rata terkecil adalah G711 A-law sebesar 0,838 ms. Packet loss untuk semua codec yang diujikan adalah 0%. Throughput pada paket data terbesar saat menggunakan codec GSM FR yaitu 18,139 kbps. Codec yang direkomendasikan adalah G711 A-law karena lebih stabil dari segi jitter dan codec GSM FR cocok diimplementasikan pada jaringan yang memiliki bandwitdh kecil.
Менталитет тувинцев в горизонте социокультурной феноменологии Питирима Сорокина
Authors: Tyugashev Evgeny A. , Popkov Yuri V. 
Published: September 2017

В статье представлен оригинальный подход в исследовании этнического менталитета тувинцев, который заключается в его феноменологическом описании. Подход строится на систематике соответствующих явлений, их типологии и классификации. В контексте формулируемых феноменологических теорий возможна не только индивидуализированная характеристика, но и эмпирическая диагностика менталитетов отдельных народов. В качестве фундаментальной базы для решения поставленной задачи используется творческое наследие выдающегося российско-американского социолога П. А. Сорокина, которое содержит развернутое феноменологическое учение о менталитетах культуры. Именно это учение лежит в основании анализа тувинского менталитета. Показано, что в категориях учения П. А. Сорокина социокультурная динамика менталитета тувинцев состоит в циклической смене псевдоидеационального и идеалистического менталитетов, из которых последний воспринимается как норма традиционной культуры.

Published: September 2017

Objective.There is a need for a cognitive function screening test that can be administered to patients with systemic lupus erythematosus (SLE) in clinic. The objectives of this study were to determine (1) prevalence of cognitive impairment (CI) in SLE by the Montreal Cognitive Assessment (MoCA), Mini Mental State Examination (MMSE), in relation to the Hopkins Verbal Learning Test–Revised (HVLT-R), and Perceived Deficits Questionnaire 5-Item (PDQ-5); and (2) associated factors with CI.Methods.Consecutive patients followed at a single center were recruited. HVLT-R, MoCA, and MMSE were administered. Sensitivity/specificity, positive (PPV)/negative (NPV) predictive values, and positive likelihood ratio (LR+) of MoCA/MMSE were determined (compared to HVLT-R). A test on intellectual ability and questionnaires on anxiety, depression, and perceived cognitive deficits were completed. Regression analyses determined associations with CI.Results.Of 98 patients, 48% had CI using MoCA and 31% using HVLT-R. Sensitivity was higher for MoCA (73%) compared to MMSE (27%), though MMSE was more specific (90%) than MoCA (63%). PPV and LR+ were similar in MoCA and MMSE (PPV: 47%, 53%; LR+: 2.0, 2.6, respectively), but NPV was higher in MoCA (84%) than MMSE (74%). PDQ-5 predicted objective CI (HVLT-R: sensitivity 100%, specificity 89%). Although CI was associated with depression in univariate analyses, it did not hold in the multivariate analysis, while longer SLE disease duration and more years of education remained significant.Conclusion.CI is highly prevalent and MoCA may be a useful tool to screen for CI in SLE. Patients with more years of education were less likely to have CI.

Abstract
Systemic lupus erythematosus (SLE) is a highly heterogeneous disease with limited therapeutic options, where clinical manifestations are the result of activation of innate and adaptive immune mechanisms. The elucidation of these mechanisms is critical for identifying novel therapeutic targets and agents that are more likely to benefit individual patients. In this study we investigated the role that CD8+ T cells play in SLE. We studied CD8+ T cell activity in two different cohorts of SLE patients under standard of care (n = 65 total). The analyses included phenotyping of T cell differentiation, intracellular cytokine staining, and whole blood gene expression. We identified a subset of SLE patients (between 30 and 45%) with elevated numbers of terminally differentiated CD8+ T cells, identified as CCR7−CD45RAint-hiCD28−. We refer to this phenotype as cytotoxic, as it is accompanied by an increase in perforin and granzyme B expression and is correlated with a whole blood gene module of cytotoxic activity (p &lt; 5 × 10−9). Consistent with the potential for tissue damage, this cytotoxic phenotype associates with lupus nephritis (p &lt; 0.02). We have identified an SLE endophenotype, characterized by the increase in terminally differentiated CD8+ T cells that correlated with cytotoxic signature and renal manifestations of the disease. These findings suggest that this subgroup of SLE patients may benefit specifically from therapies that block CD8+ T cell activation and differentiation.
The Scaffolding Protein IQGAP1 Interacts with NLRC3 and Inhibits Type I IFN Production

Abstract
Sensing of cytosolic nucleotides is a critical initial step in the elaboration of type I IFN. One of several upstream receptors, cyclic GMP–AMP synthase, binds to cytosolic DNA and generates dicyclic nucleotides that act as secondary messengers. These secondary messengers bind directly to stimulator of IFN genes (STING). STING recruits TNFR-associated NF-κB kinase–binding kinase 1 which acts as a critical node that allows for efficient activation of IFN regulatory factors to drive the antiviral transcriptome. NLRC3 is a recently characterized nucleotide-binding domain, leucine-rich repeat containing protein (NLR) that negatively regulates the type I IFN pathway by inhibiting subcellular redistribution and effective signaling of STING, thus blunting the transcription of type I IFNs. NLRC3 is predominantly expressed in lymphoid and myeloid cells. IQGAP1 was identified as a putative interacting partner of NLRC3 through yeast two-hybrid screening. In this article, we show that IQGAP1 associates with NLRC3 and can disrupt the NLRC3–STING interaction in the cytosol of human epithelial cells. Furthermore, knockdown of IQGAP1 in THP1 and HeLa cells causes significantly more IFN-β production in response to cytosolic nucleic acids. This result phenocopies NLRC3-deficient macrophages and fibroblasts and short hairpin RNA knockdown of NLRC3 in THP1 cells. Our findings suggest that IQGAP1 is a novel regulator of type I IFN production, possibly via interacting with NLRC3 in human monocytic and epithelial cells.

Abstract
IL-19, a member of the IL-10 cytokine family that signals through the IL-20 receptor type I (IL-20Rα:IL-20Rβ), is a cytokine whose function is not completely known. In this article, we show that the expression of IL19 in biopsies of patients with active ulcerative colitis was increased compared with patients with quiescent ulcerative colitis and that colitis was attenuated in IL-19–deficient mice. The disruption of the epithelial barrier with dextran sodium sulfate leads to increased IL-19 expression. Attenuated colitis in IL-19–deficient animals was associated with reduced numbers of IL-6–producing macrophages in the inflamed colonic lamina propria. Microbial-driven expression of IL-19 by intestinal macrophages may contribute to the pathogenesis of inflammatory bowel disease.
Colouring Squares of Claw-free Graphs
Authors: de Joannis de Verclos Rémi , Kang Ross J. , Pastor Lucas 
Published: September 2017

AbstractIs there some absolute $\unicode[STIX]{x1D700}>0$ such that for any claw-free graph $G$, the chromatic number of the square of $G$ satisfies $\unicode[STIX]{x1D712}(G^{2})\leqslant (2-\unicode[STIX]{x1D700})\unicode[STIX]{x1D714}(G)^{2}$, where $\unicode[STIX]{x1D714}(G)$ is the clique number of $G$? Erdős and Nešetřil asked this question for the specific case where $G$ is the line graph of a simple graph, and this was answered in the affirmative by Molloy and Reed. We show that the answer to the more general question is also yes, and, moreover, that it essentially reduces to the original question of Erdős and Nešetřil.
Cost, Contractors and Scale: An Empirical Analysis of the California Solar Market
Authors: Mauritzen Johannes 
Published: September 2017

ABSTRACT This paper presents an empirical analysis of the rapidly growing California rooftop solar photovoltaic market using detailed data of over 100,000 solar installations between 2007 and 2014. The rapid fall in the cost of solar panels stand central in the expansion of this market. I use a semi-parametric regression model to aid identification of cost factors by decomposing time-varying and cross-sectional components. I find that the use of Chinese manufactured panels are associated with costs that are 6% lower. Economies of scale at the local level (number of yearly installations in a zip code) and at the installation level (size of the installation) are also associated with lower costs. Higher subsidies, and higher contractor market-share are associated with higher costs. I use an exploratory analysis of the dominant contractor, SolarCity, to discuss non-cost factors in the expansion of the solar photovoltaic market.

Abstract
Since 2005, the National Institute of Standards and Technology (NIST) has collaborated with the National Institutes of Health (NIH), Office of Dietary Supplements (ODS) to improve the quality of measurements related to human nutritional markers of vitamin Dstatus. In support of the NIH-ODS Vitamin D Initiative, including the Vitamin D Standardization Program (VDSP), NIST efforts have focused on (1) development of validated analytical methods, including reference measurement procedures (RMPs); (2) development of Standard ReferenceMaterials (SRMs); (3) value assignment of critical study samples using NIST RMPs; and (4) development and coordination of laboratory measurement QA programs. As a result of this collaboration, NIST has developed RMPs for 25-hydroxyvitamin D2 [25(OH)D2], 25(OH)D3, and 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3]; disseminated serum-based SRMs with values assigned for 25(OH)D2, 25(OH)D3, 3-epi-25(OH)D3, and 24R,25(OH)2D3; assigned values for critical samples for VDSP studies, including an extensive interlaboratory comparison and reference material commutability study; provided an accuracy basis for the Vitamin D External Quality Assurance Scheme; coordinated the first accuracy-based measurement QA program for the determination of 25(OH)D2, 25(OH)D3, and 3-epi-25(OH)D3 in human serum/plasma; anddeveloped methods and SRMs for the determination of vitamin D and 25(OH)D in food and supplement matrix SRMs. The details of these activities and their benefit and impact to the NIH-ODS Vitamin D Initiative are described.
Percepciones de la crisis en 'El último verano', del colectivo NOPHOTO / Sensing the crisis in Nophoto’s 'El último verano'
Authors: Snyder Haight Jonathan David 
Published: September 2017

Resumen: El proyecto fotográfico El último verano (2012) del colectivo NOPHOTO, ofrece un conjunto de percepciones fragmentadas, y a veces contradic-torias, sobre una cotidianidad estructurada por la crisis económica. Partiendo de la noción del impasse neoliberal de Lauren Berlant, este análisis aborda las formas en que la crisis resulta perceptible en las fotos, primero en el apego afectivo del sujeto hacia sus pérdidas anticipadas, y después en las tácticas de supervivencia desarrolladas en tiempos de crisis. El hecho de hacer un balance del presente en el impasse, parece estar inmerso en estas fotografías con un fuerte sentido de temporalidad en el que el cambio y la pérdida desestabilizan el presente, evocando senti-mientos de retorno, nostalgia, proyección futura, fantasía escapista, ansiedades sobre las perspectivas de riesgo, etc. Y en las fotografías, el carácter compuesto del proyecto señala a los espectadores otras formas de mirar en tiempos de crisis, desde perspectivas plurales, que en su conjunto ensamblan una circunstancia colectiva y compartida de la vida cotidiana en tiempos de austeridad
Palabras clave: fotografía documental, crisis financiera, neoliberalismo, temporalidad, afecto, subjetividad.
Abstract: NOPHOTO’s collective photography project El último verano provides a fragmented, contradictory document to the deteriorating conditions of everyday life in times of crisis. In it, nine photographers turn their lenses toward portraits of downward mobility, precarity, and the growing phenomenon of emigration, as well as summer pleasures and moments of escape. Drawing from Lauren Berlant’s writings on the impasse in neoliberalism, I read how la crisis is sensed first in these photos in the subject’s affective attachments to perceptible losses and then in strategies for survival developed amid an ongoing crisis. Taking stock of the present at an impasse, I argue, is immersed in a strong sense of temporality for the present ungrounded by change—of nostalgia and return, of future projection, of escapist fantasy, of present anxieties for risk—and in the photographs, indexes for viewers other narratives on the crisis, in plural ways, that piece together a collective, shared circumstance in times of austerity.
Key Words: documentary photography, financial, crisis, neoliberalism, temporality, affect, subjectivity.
