Genetic Trends in Winter Wheat Yield and Test Weight under Dual‐Purpose and Grain‐Only Management Systems
Authors: Khalil Iftikhar H. , Carver Brett F. , Krenzer Eugene G. , MacKown Charles T. , Horn Gerald W.
Published: July 2017

Wheat (Triticum aestivum L.) cultivars of the southern Great Plains are traditionally bred in environments managed for grain production only but are commonly grown for the dual‐purpose of producing winter forage and grain from the same crop. To what extent grain yield and test weight are consistently expressed in those environments requires investigation relative to long‐term attempts to improve them genetically. A historical set of hard red winter (HRW) wheat cultivars was evaluated under grain‐only and dual‐purpose management systems to compare their agronomic performance and derived estimates of genetic progress. Separate experiments were established for each system featuring whole‐plot treatments of a foliar fungicide and split‐plot treatments of 12 cultivars. The study was conducted for 3 yr at the Wheat Pasture Res. Ctr. near Marshall, OK. Dual‐purpose experiments were generally grazed from November through February. Yield in the grain‐only system improved 18.8 kg ha−1 yr−1, equivalent to 1.3% of the mean yield for Turkey. The rate of progress in the dual‐purpose system was significantly lower at 11.3 kg ha−1 yr−1, equivalent to 0.9% of the mean for Turkey. Management for grazing had a more profound influence on estimates of yield improvement than did management for disease protection. Linear trends in test weight were not evident under either system, nor were cultivar differences influenced by management system consistently across years. Breeding practices should emphasize selection for grain yield in both environments if future progress is to be maximized in both.

Published: July 2017

Crop model testing in diverse environments is essential if modelers wish to make applications or extrapolations to those environments. A recent study demonstrated the effectiveness of optimization techniques for deriving cultivar coefficients for the CROPGRO‐Soybean model from typical information provided by soybean performance tests. The objectives of this study were (i) to explore the extent to which cultivar coefficients developed by these approaches from crop performance tests are stable across different regions, (ii) to test the CROPGRO‐Soybean model's ability to predict phenology and seed yield using cultivar coefficients that were developed in different regions, and (iii) to investigate whether 3 yr of crop performance data are adequate for developing stable genetic coefficients. A stepwise procedure was applied to derive cultivar coefficients for 10 common cultivars grown in different environments in Georgia and North Carolina. Regarding the transportability of cultivar coefficients across states, we found that the critical daylength coefficients were the most reliable cultivar traits. We found less stability of the cultivar traits that control genetic differences in seed yield potential. The estimated cultivar coefficients developed in Georgia enabled CROPGRO to predict yield and harvest maturity in North Carolina within 3.8% and 3.5 d, respectively, from the observed averages. Using the cultivar coefficients developed from North Carolina environments allowed us to simulate the actual mean yield and harvest maturity in Georgia to within 2.5% and 2.0 d. Furthermore, the model's ability to predict seed yield and maturity with cultivar coefficients developed from 3 yr of data was nearly as good as that derived from much larger data sets.
Effect of reagents used during detection and quantification of Ascaris suum in environmental samples on egg viability
Authors: Amoah Isaac Dennis , Reddy Poovendhree , Stenström Thor Axel
Published: July 2017

Soil-transmitted helminths (STHs) are a major health concern globally. Infection is mostly through contact with contaminated water, food or soil. Therefore to break the cycle of viable transmission STH eggs must be quantitatively detected in the environment. The effect of different reagents on the viability of Ascaris suum eggs during laboratory detection and quantification was assessed and different incubation solutions compared. Sulphuric acid gave a slightly higher recovery percentage of viable eggs (91.2%) than distilled water (90.0%) and 0.5% formalin (87.6%), although the difference was not statistically significant (p > 0.05). Acetoacetic acid, ethyl acetate, ammonium bicarbonate, zinc sulphate, magnesium sulphate and Tween 80, are reagents widely used in test protocols for the detection and quantification of STH eggs. Eggs were exposed to these reagents for different time durations. Acetoacetic acid resulted in the highest loss of viability (3.4 ± 0.7% viable), while magnesium sulphate resulted in the least effect (88.5 ± 1.2% viable). In conclusion the use of the selected reagents in the detection of these eggs was found to affect the viability of exposed eggs, especially during prolonged exposures. Therefore we recommended that eggs be exposed for ≤5 minutes, to reduce the risk of viability loss.
JQ1, a BET Inhibitor, Synergizes with Cisplatin and Induces Apoptosis in Highly Chemoresistant Malignant Pleural Mesothelioma Cells
Authors: Zanellato Ilaria , Colangelo Donato , Osella Domenico
Published: July 2017

Background:

Malignant Pleural Mesothelioma (MPM) is an asbestos-associated tumor
with poor prognosis and few therapeutic options. JQ1, a selective antagonist of BRD4, modulates
transcription of oncogenes, including MPM chemoresistance-associated c-Myc and Fra-1.

Objective:

We investigated if JQ1 could enhance the efficacy of cisplatin against MPM.

Methods:

The antiproliferative activity of cisplatin in combination with JQ1 was assessed on MPM
cell lines representative of the cellular phenotypes of this tumor (epithelioid, sarcomatoid and biphasic),
and on one cisplatin resistant sub-line. The combination schedule was optimized adopting a 3Dspheroid
model. Drug combination effects were correlated with cell cycle distribution and senescence-
associated β-galactosidase positive cells. The expression of c-Myc and Fra-1 proteins and
some apoptosis markers was assessed by immunoblotting and RT-qPCR. DNA damage and repair
were evaluated by means of alkaline comet assay.

Results:

JQ1 in combination with cisplatin elicited additive or synergistic (superadditive) antiproliferative
effects on MPM cells, depending on the cell line. The combination showed tumor regression
on the 3D-spheroid model. It induced increased apoptosis, along with decreased c-Myc and, sometimes,
Fra-1 expression. JQ1 decreased cisplatin-induced DNA breaks in all MPM cells and increased
senescence even in less proficient cells, thus enhancing the DNA Damage Response (DDR).

Conclusion:

The superadditive effect is due to c-Myc repression. The consequent DDR enhancement
triggers to apoptosis induction and/or permanent growth arrest (senescence), depending on the
MPM cellular context, leading to tumor regression. Thus, the pharmacological modulation of BET
activity could represent a promising tool for future MPM therapy.
MicroRNA Key to Angiogenesis Regulation: MiRNA Biology and Therapy
Authors: Tiwari Ankit , Mukherjee Bratati , Dixit Manjusha
Published: July 2017

Angiogenesis is involved in maintaining normal physiological processes like embryonic
development, wound healing, inflammation and reproduction. Pathogenesis of various diseases like
diabetic retinopathy, rheumatoid arthritis and cancer are associated with imbalanced angiogenesis.
Angiogenic stimulators and inhibitors act together for keeping angiogenic switch in balance. Recently,
miRNAs have been found to regulate various stages of angiogenesis. miRNAs are 21-23 nucleotides
long, single stranded, noncoding RNA molecules generated endogenously. miRNA's ability
to target multiple genes within a signaling pathway makes them promising target for the development
of second generation anti-angiogenesis drugs. This review was conceived with the notion of
availability of specific and comprehensive knowledge about AngiomiRs at one place. This will facilitate
the research in basic understanding and in the development of new drugs.

In this review, we have summarized the biology and therapeutic potential of the miRNAs, which are
involved in controlling angiogenesis process. In miRNA biology, we have provided the updated
summary of miRNAs in the regulation of endothelial cells, showed role of miRNAs in the signaling
pathways of angiogenesis and, discussed the gaps in complete knowledge of mechanism. We have
also provided exclusive insights regarding therapeutic potential of these miRNAs, in angiogenesis
related disorders. Additionally, we have discussed the challenges in miRNA based drug delivery and
updated the current efforts in the development of miRNA delivery methods. Though much research
is needed to discover the complete miRNA network regulating angiogenesis but once it is done, targeting
miRNA may be considered as a potential candidate for therapeutic invention against angiogenesis
related disorders.
Bond Capability of Universal Adhesive Systems to Dentin in Self-etch Mode after Short-term Storage and Cyclic Loading
Authors: Costa Daniele Morosini , Somacal Deise Caren , Borges Gilberto Antonio , Spohr Ana Maria
Published: July 2017

Objective:

The aim was to evaluate, in vitro, the tensile bond strength to dentin of Scotchbond Universal (SU), All-Bond Universal (AU) and One Coat 7 Universal (OC7) adhesives applied in self-etch mode, after 24 h of storage and after 500,000 loading cycles, using Clearfil SE Bond (SE) as a control.

Materials and Methods:

The adhesives were applied on the dentin of bovine teeth, followed by the application of a composite resin. Thirty specimens were obtained for each adhesive. Half of the specimens were submitted to cyclic loading for 500,000 cycles. All specimens were submitted to a tensile bond strength test in a universal testing machine at a crosshead speed of 0.5 mm/minute.

Results:

According to two-way ANOVA and Tukey’s test (α=5%), the interaction between the adhesive and cyclic loading factors was significant (p=0.001). The means followed by the same letter represent no significant difference in the bond strength (MPa) after 24 h: OC7=7.86A (±2.90), SU=6.78AB (±2.03), AU=5.61BC (±2.32), and SE=3.53C (±1.89). After cyclic loading, SE, SU and AU maintained bond strength comparable to 24 h period. There was a significant decrease only for OC7.

Conclusion:

SU, AU and OC7 had bond strength to dentin comparable to that of SE. Only OC7 had decreased bond strength to dentin after cyclic loading.
A Study of the Surface Air Temperature Variations in Nigeria
Authors: Yusuf Najib , Okoh Daniel , Musa Ibrahim , Adedoja Samson , Said Rabia
Published: July 2017

Background:

Simultaneous measurements of air temperature were carried out using automatic weather stations at 14 tropical locations in Nigeria. Diurnal variations were derived from the 5-minute update cycle initial data for the years ranging between 2007 and 2013. The temperature trends in Nigeria revealed a continuous variability that is seasonally dependent within any particular year considered.

Method:

The analysis was carried out using available data from the network and the results are presented with a focus to characterize the temperature variations at different locations in the country using the mean, maximum and minimum temperatures from the north which is arid in nature to the south, which is a tropical monsoon climate type and a coastal region.

Result:

In overall, temperature variations in Nigeria were observed to have higher values in the far north, attributed to the influence of Sahara Desert, which has less cloud cover and therefore is more transparent to solar irradiance and lowers values in the south, where there are more cloud cover and abundant vegetation.

Conclusion:

Measured maximum and minimum temperatures in Nigeria are respectively 43.1°C at Yola (north-east part of Nigeria) and 10.2°C for Jos (north-central part of Nigeria). The least temperature variations were recorded for stations in the southern part of the country, while the largest variations were recorded in the north-central region of the country.
Cholesterol Screening and Statin Prescription is Low Among HIV-Infected Patients on Protease-Inhibitor Regimens in Botswana
Authors: Mosepele M. , Letsatsi V. , Mokgatlhe L. , Hudson F.P. , Gross R.
Published: July 2017

Background:

Little is known about the use of statin for cardiovascular disease (CVD) risk reduction among HIV-infected patients on protease inhibitors (PI`s) in sub-Saharan Africa (SSA).

Objective:

Cholesterol screening and statin use were retrospectively assessed among HIV-infected participants on PI`s between 2008 and 2012 at a large urban HIV clinic in Botswana.

Methods:

Proportion of participants screened per year was calculated and statin indication was assessed using atherosclerosis CVD (ASCVD) and Framingham risk (FRS) scores as of the year 2012 guidelines.

Results:

Cholesterol screening ranged between 19% and 30% per year (2008-2011) but increased to 80% after study enrollment. The rate of hypercholesterolemia (> 5.0 mmol/L) was 31% in 2012. Fewer than 1% participants were on statin therapy but 14.3% and 9.4% had statins indicated by ASCVD and FRS respectively.

Conclusion:

The high proportion of participants indicated for, but not prescribed statins highlights a substantial gap in the care to reduce CVD risk among these patients.
Study of Evaluation of Symptoms of Juvenile Recurrent Parotitis Prior to and After Sialendoscopy
Authors: Faizal Bini , Abraham Sania Mariam , T Krishnakumar
Published: July 2017

Background:

Juvenile recurrent parotitis(JRP) causes recurrent pain and swelling of one or both parotid glands in children. They are subjected to repeated courses of antibiotics and analgesics for this condition. Though self- limiting, some may progress to chronic parotitis which in some instances result in parotidectomy later on. But it does affect quality of life of the child with poor feeding during attacks and school absenteeism. Among various therapies, steroid lavage under endoscopic visualisation of the parotid salivary duct system has become popular after the advent of sialendoscopy. There are few studies comparing the response to conservative measures and salivary endoscopy.

Objective:

To evaluate the efficacy of sialendoscopy over medical management in JRP.

Methodology:

Twenty two patients of JRP between the age group 3 to 18 years were enrolled in this study. This retrospectively analysed the frequency of pain and parotid swelling after sialendoscopy. The results were compared to their pre intervention status when they were on medical management. Sialendoscopic management was offered only to those patients under medical treatment with symptoms of two or more attacks in 6 months.

Results:

Conservative measures as well as salivary endoscopy had good results, but latter fared better with regard to pain score and long remission. Majority were asymptomatic and the symptomatic patients experienced less pain with longer remission between attacks.

Conclusion:

Sialendoscopic visualisation and lavage seems to be a promising tool in the management of JRP. It appears that it contains the inflammatory process better and may prevent the progression to chronic parotitis.

Authors: Kharizsa Ayu , Priyanto Sigit , Jopson Ann
Published: July 2017

Aims of this research are to determine the prominent factor behind car dependency, examine the correlation between the factors that indicate car dependency, and the correlation between social status and car use in Jakarta. The primary question of this research is “What are the influence factors behind car dependency in Jakarta? Does prestige influence car use behavior in Jakarta?” By using Jakarta as a case study, the research applies Factor Analysis and Logistic Regression Analysis based on Theory of Planned Behavior. It used to measure individual’s behavior based on attitudes toward behavior, subjective norm, and perceive behavior. The result shows that factors of dependency in term of car users consist of the starting place, habits, and control belief. While factors on car dependency for car users on occasion are intention and control belief. Correlation between prestige and car use is identified based on attitudes and subjective norm. For car users, attitudes are influenced by higher degrees of prestige which is slightly contrary to people who use cars occasionally. Other indicators of prestige are car types which can influence people’s behavior in using the car. The conclusion which can be drawn from the results are no significant correlation found between car dependency and social status, but significant in the case of correlation between car use and social status.

Authors: Posso Chaparro María Isabel , Chica Velásquez Mónica Fernanda , Gallego Sandra Mónica
Published: July 2017

Se identifica el impacto psicológico de la exposición indirecta y directa a la violencia, evidenciado en tres cuadros clínicos como son la ansiedad, la depresión y el trastorno de estrés postrauma (TEPT), de 70 menores de ambos sexos, con edades entre los 8 y 12 años pertenecientes a dos casas de protección del ICBF5 y a una institución educativa de la ciudad de Cali. La investigación fue de tipo transversal con un diseño ex post facto retrospectivo. Los instrumentos empleados fueron la Escala revisada de Ansiedad Manifiesta para niños, CMAS-R (Reynold y Richmond, 1978), el Cuestionario Child Depression Inventory, CDI (Kovacks, 1981); el Trauma Symptoms Checklist for Children (TSCC), (Briere, 1996) y el Cuestionario de exposición a violencia (CEV), (Cuevas, Peña y Varela, 2003; Cuevas, 2004). Los resultados de la investigación indican que los niños están siendo víctimas de la exposición a la violencia de manera directa e indirecta, fenómeno que conduce a la pérdida de vidas humanas y a la trasgresión de la integridad física, moral y psicológica de los implicados. Sobre todo de los menores quienes en los últimos tiempos han sido los más afectados, sufriendo como consecuencia un gran impacto psicológico.
La felicidad, un asunto de niños
Authors: Chala Trujillo Mabel Goretty
Published: July 2017

La felicidad es un estado anhelado por los seres humanos y a la vez, es un tema que resulta de interés para los investigadores. Este artículo describe las experiencias de felicidad descritas por 60 niños y niñas, matriculados en instituciones públicas de Bogotá, Neiva y Pasto (Colombia) durante el año 2013. Desde el enfoque cualitativo y el diseño metodológico Relatos de Vida, se buscó conocer el significado sobre felicidad que construyen los las niñas y los niños escolarizados con edades en edades entre 9 y 11 años en las mencionadas ciudades. Los participantes se refieren a la felicidad como una vivencia de la cotidianidad, disfrutando de compañía de seres queridos, del juego y de actividades sencillas en las que pueden compartir con otros. Se sienten felices cuando sus necesidades básicas están satisfechas, cuando son reconocidos y aceptados y/o cuando pueden interactuar con sus pares o sus familiares positivamente. La discusión se centra en la concordancia entre la vivencia de emociones positivas, lo cual genera estados de bienestar y satisfacción y el significativo aporte que pueden brindar los adultos a la felicidad de niños y niñas, cuando los reconocen como seres singulares, con necesidades particulares, y se ocupan de satisfacerlas.

Published: July 2017

Los discursos de la identidad nacional a partir de la Selección Nacional de Colombia (SNC) han sido el tema de varias investigaciones. En especial, la academia se ha centrado en los medios de comunicación masiva y en el de los hinchas para entender las estrategias de esta clase de manifestaciones. En este estudio se analizan cuatro discursos presidenciales, emitidos durante la presentación de la SNC en la Copa Mundo Brasil-2014. El estudio muestra que, para apoyar los Diálogos de Paz, y por esta vía, su reelección, Juan Manuel Santos empleó varios imaginarios populares, como la unidad, la identidad y la fortaleza, excusado en las victorias del combinado nacional. De acuerdo con el presidente, la SNC representaba el sentido de nacionalidad.

Penelitian untuk mengetahui penyebab masih bertahannya pedagang tuak di Desa Datah, karena kondisi desa yang tandus menyebabkan pekerjaan bercocok tanan lebih cocok dilakukan saat musim hujan saja, karena kondisi desa yang tandus sehingga tanah lebih cocok ditanami pohon aren. Selain hasil berupa minuman keras (tuak), pohonya juga dapat memberikan manfaat ekonomis bagi pemilik pohon aren tersebut, dikarenakan hasil dari daun pohon aren tersebut dapat dijual yang untuk selanjutnya dapat dimanfaatkan sebagai sarana upacara keagamaan. Hasil dari buah dan daun pohon aren tersebut juga memerlukan waktu untuk memanennya, namun menyadap tuak dapat dilakukan setiap hari sehingga langsung dapat dijual ke konsumen. Jadi menjual tuak dapat dikatakan pekerjaan utama karena dari hasil menjual tuak tersebut mereka langsung dapat gunakan untuk memenuhi kebutuhan hidup keluarga. Keadaan seperti ini yang menyebabkan banyak penjual tuak tidak bisa berbuat banyak untuk hidupnya dan sulit beralih kepekerjaan lain.Kata Kunci: Tuak (Alkohol Bali), Sosial dan Ekonomi, Desa Datah

Mujeres y criminalidad: un estudio sobre la participación de las mujeres en el cultivo de cannabis en el Vale do São Francisco, Brasil
Authors: Pontes Fraga Paulo Cesar , Do Nascimento Silva Joyce Kel , Da Silva Martins Rogéria
Published: July 2017

Este artículo presenta los resultados de una investigación donde se analizó la participación femenina en los plantíos ilícitos de cannabis en ciudades del Vale do Rio São Francisco, en el nordeste brasileño. Aquí se presentan los relatos de vida de cinco mujeres que estuvieron involucradas en esta actividad. Las entrevistas a profundidad buscan elementos objetivos y subjetivos de las relaciones entre las entrevistadas y las instituciones y los actores relacionados con ese ilícito, revelando que aun en una actividad donde predomina la presencia masculina, la participación femenina merece ser destacada por: a) influir en el aumento de la productividad y rentabilidad de los cultivos; b) su relación con el desempeño de actividades específicas; y c) la relativa protección de la represión policiaca y la violencia, derivada de que su actividad no suele vincularse con la construcción de una carrera criminal y tiene cierta invisibilidad.

Sustainable transport policy - An evaluation of Singapore's past, present and future
Authors: Lee Der-Horng , Palliyani Sreyus
Published: July 2017

The whole world is in a fuel crisis nearly approaching exhaustion, with climate change knocking at our doorsteps. In the fight against global warming, one of the principle components that demands technocratic attention is Transportation, not just as a significant contributor to atmospheric emissions but from a much broader perspective of environmental sustainability. From the traditional technocratic aspect of transport planning, our epiphany comes in the form of Land Use integrated sustainable transport policy in which Singapore has been a pioneer, and has led the way for both developed and developing nations in terms of mobility management. We intend to investigate Singapore’s Transport policy timeline delving into the past, present and future, with a case by case analysis for varying dimensions in the present scenario through selective benchmarking against contemporary cities like Hong Kong, London and New York. The discussions will include themes of modal split, land use policy, vehicular ownership, emission policy, parking policy, safety and road traffic management to name a few. A visualization of Singapore’s future in transportation particularly from the perspective of automated vehicles in conjunction with last mile solutions is also detailed.
Infrastructure provision in developing Asia's giants: A comparative perspective on China, India, and Indonesia
Authors: Abiad Abdul , Teipelke Renard
Published: July 2017

This paper provides a comparative perspective on infrastructure provision in developing Asia's three largest countries: China, India, and Indonesia. It discusses their achievements and shortfalls in providing network infrastructure (energy, transport, water, and telecommunications) over the past two decades. It documents how three quite distinct development paths—and very differentlevels of national saving and investment—were manifested in different trajectories of infrastructure provision. The paper then describes the institutional, economic, and policy factors that enabled or hindered progress in providing infrastructure. Here, contrasting levels of centralization of planningplayed a key role, as did countries’ differing abilities to mobilize infrastructure-related revenue streams such as user charges and land value capture. The paper then assesses future challenges for the three countries in providing infrastructure in a more integrated and sustainable way, and links these challenges with the global development agenda to which the three countries have committed. The concluding recommendations hope to provide a platform for further policy and research dialogue.
Pháp luật về các biện pháp hạn chế rủi ro trong hoạt động cho vay của tổ chức tín dụng ở Liên bang Nga và bài học kinh nghiệm cho Việt Nam
Authors: Lê Thị Thuỷ Thu
Published: July 2017

Hệ thống ngân hàng đóng vai trò quan trọng trong việc phát triển các quan hệ kinh doanh, thương mại giữa các chủ thể trong nền kinh tế thị trường hiện nay. Ngân hàng là trung gian giữa người đi vay (cá nhân, tổ chức có nhu cầu về vốn) và người cho vay (người gửi tiền), trên cơ sở đó đảm bảo sự luân chuyển vốn nhịp nhàng giữa người thừa vốn và người thiếu vốn. Tuy nhiên, để đảm bảo sự hoàn trả các nguồn vốn vay và hạn chế rủi ro trong hoạt động cho vay, ngân hàng phải áp dụng nhiều biện pháp.

This study aimed at comparing students‟ ability in writing descriptive text withblogtechnique and without blog. This study is used to answer the questions: Is thereany significant difference in the achievement between the students who wrotedescriptive text with blogtechnique and the students who wrote descriptive text withoutblog? And how well the students write descriptive text after being taught by using blog.Quantitative method was used in analyzing the gathered data. The basic outline showedthat in the writing skill, the second year students in the first semester of Junior HighSchool are supposed to write a descriptive text, so the data weredescriptive textswritten by two classes of the second year students of MTs Brangsong Kendal as thesample. One of them was the experimental group and the other one was the controlgroup. The result of the study shows that Blog technique applied in writingdescriptiontexts of VIIIgrade of MTs Brangsong, Kendal, actually gave contribution in improvingthe students‟ skill in writing descriptive texts. This technique could be an effectivemethod. It is proper since there was a significant difference between the control groupand the experimental group when the study was conducted. Based on the statisticalanalysis, it could be seen that the students‟ in the experimental group was improvinghigher than the control group. The mean of the experimental group was higher (from71.81to 80.11) than the control group (from 71.72 to 74.61). The t-value for two meansof post-test was 4.170; meanwhile the critical value at α = 5% was 1.67. Since the tvaluewas in the Ho rejection area, it was concluded that there is a significantdifference in the achievement between the students in control group who were not giventhe treatment and the experimental group who were given the treatment (Blogtechnique). By using this technique in the experimental class, the class situation wasvery enjoyable, the students freely communicated to each other to share their ideas.The writer had observed that the writing descriptive texts scores of the experimentalclass were higher than those of the students who wrote descriptive text without Blog.Keywords: Blog, Descriptive Text, WritingSkill
The effectiveness of process genre and product genre approaches to teach writing to introvert and extrovert students (the case of the tenth year students of state senior high school 1 Wirosari-Grobogan in the academic year of 2013/2014)

This present study aims to investigate the effectiveness of Process Genreand Product Genre Approaches to teach writing to introvert and extrovertstudents. A quasi-experimental study with 2x2 factorial designs was conductedto gain answers. Data were collected by using Myers Briggs Type Indicator,observation notes and a pre-and-posttest. Data were analyzed by using T-test,Two-Way Anova, and Tukey test. The findings revealed that first, ProcessGenre Approach was significantly effective to be used to teach writing to boththe introvert and extrovert students; while, the Product Genre Approach wasonly effective to be used to teach writing to the extrovert students. Second,quantitatively, the Process Genre Approach was not significantly more effectiveto be used to teach writing compared to the Product Genre Approach. Third,the students‟ personalities significantly influenced their writing quality, inwhich the extrovert students‟ writings were better than the introvert students‟writings. Fourth, there was a significant interaction occurred between theteaching approaches and the students‟ personalities on their writing quality.Based on the study results, the researcher suggests English teachers to considerusing Process Genre Approach in their writing classes and identify eachstudent‟s personality in the very beginning of lessons, acknowledging that thestudents‟ personalities significantly influence the students‟ writing quality.Keywords: Process Genre Approach; Student’s Personality; Writing Instruction
Quantum description of a field in macroscopic electrodynamics and photon properties in transparent media
Authors: Toptygin I N
Published: July 2017

Applying a quantum mechanical treatment to a high-frequency macroscopic electromagnetic field and radiative phenomena in a medium, we construct quantum operators for energy–momentum tensor components in dispersive media and find their eigenvalues, which are different in the Minkowski and Abraham representations. It is shown that the photon momentum in a medium resulting from the quantization of the vector potential differs from that defined from Abraham’s symmetric energy–momentum-tensor but is equal to the momentum defined from the Minkowski tensor. A similar result is obtained by calculating the intrinsic angular momentum (spin) of an electro-magnetic field in the medium. Only the Minkowski tensor leads to the experimentally confirmed spin values that are multiples of ħ, providing the grounds for choosing the Minkowski representation as the proper form for the momentum density of a transverse electromagnetic field in a transparent medium, in both classical and quantum descriptions of the field. The Abraham representation is unsuitable for this purpose and leads to contradictions. The conclusion drawn does not apply to quasistatic and static fields.
Areal-Averaged Spectral Surface Albedo in an Atlantic Coastal Area: Estimation from Ground-Based Transmission

Tower-based data combined with high-resolution satellite products have been used to produce surface albedo at various spatial scales over land. Because tower-based albedo data are available at only a few sites, surface albedos using these combined data are spatially limited. Moreover, tower-based albedo data are not representative of highly heterogeneous regions. To produce areal-averaged and spectrally-resolved surface albedo for regions with various degrees of surface heterogeneity, we have developed a transmission-based retrieval and demonstrated its feasibility for relatively homogeneous land surfaces. Here, we demonstrate its feasibility for a highly heterogeneous coastal region. We use the atmospheric transmission measured during a 19-month period (June 2009–December 2010) by a ground-based Multi-Filter Rotating Shadowband Radiometer (MFRSR) at five wavelengths (0.415, 0.5, 0.615, 0.673 and 0.87 µm) at the Department of Energy’s Atmospheric Radiation Measurement (ARM) Mobile Facility (AMF) site located on Graciosa Island. We compare the MFRSR-retrieved areal-averaged surface albedo with albedo derived from Moderate Resolution Imaging Spectroradiometer (MODIS) observations, and also a composite-based albedo. We demonstrate that these three methods produce similar spectral signatures of surface albedo; however, the MFRSR-retrieved albedo, is higher on average (≤0.04) than the MODIS-based areal-averaged surface albedo and the largest difference occurs in winter.

This paper reports the syntheses of two new complexes, [Co(L1)(H2O)2] (1) and [{Zn(L2)(μ-OAc)Zn(n-PrOH)}2] (2), from asymmetric halogen-substituted Salamo-type ligands H2L1 and H3L2, respectively. Investigation of the crystal structure of complex 1 reveals that the complex includes one Co(II) ion, one (L1)2− unit and two coordinated water molecules. Complex 1 shows slightly distorted octahedral coordination geometry, forming an infinite 2D supramolecular structure by intermolecular hydrogen bond and π–π stacking interactions. Complex 2 contains four Zn(II)ions, two completely deprotonated (L2)3− moieties, two coordinated μ-OAc− ions and n-propanol molecules. The Zn(II) ions in complex 2 display slightly distorted trigonal bipyramidal or square pyramidal geometries.
Integrating Mental and Physical Health Care for Low-Income Americans: Assessing a Federal Program’s Initial Impact on Access and Cost
Authors: Goldstein Evan
Published: July 2017

Individuals with mental health disorders often die decades earlier than the average person, and low-income individuals disproportionately experience limited access to necessary services. In 2014, the U.S. Health Resources & Services Administration (HRSA) leveraged Affordable Care Act funds to address these challenges through behavioral health integration. The objective of this study is to assess the US$55 million program’s first-year impact on access and cost. This analysis uses multivariable difference-in-difference regression models to estimate changes in outcomes between the original 219 Federally Qualified Health Center (FQHC) Behavioral Health Integration grantees and two comparison groups. The primary outcome variables are annual depression screening rate, percentage of mental health and substance use patients served, and per capita cost. The results change when comparing the Behavioral Health Integration (BHI) grantees to a propensity score-matched comparison group versus comparing the grantees to the full population of health centers. After one year of implementation, the grant program appeared ineffective as measured by this study’s outcomes, though costs did not significantly rise because of the program. This study has limitations that must be discussed, including non-randomized study design, FQHC data measurement, and BHI program design consequences. Time will tell if FQHC-based behavioral–physical health care integration will improve access among low-income, medically-underserved populations.

Platelet activation is involved in cardiovascular diseases, such as atherosclerosis and ischemic stroke. Licochalcone A (LA), an active ingredient of licorice, exhibits multiple biological activities such as anti-oxidation and anti-inflammation. However, its role in platelet activation remains unclear. Therefore, the study investigated the antiplatelet mechanism of LA. Our data revealed that LA (2–10 μM) concentration dependently inhibited platelet aggregation induced by collagen, but not thrombin and U46619. LA markedly attenuated collagen-stimulated ATP release, P-selectin secretion, calcium mobilization, and GPIIbIIIa activation, but did not interfere with the collagen binding to platelets. Moreover, LA significantly reduced the activation of PLCγ2, PKC, Akt and MAPKs. Thus, LA attenuates platelet activation, possibly by inhibiting collagen receptor downstream signaling but not by blocking the collagen receptors. In addition, LA prevented adenosine diphosphate (ADP)-induced acute pulmonary thrombosis, fluorescein sodium-induced platelet thrombus formation, and middle cerebral artery occlusion/reperfusion-induced brain injury in mice, but did not affect normal hemostasis. This study demonstrated that LA effectively reduced platelet activation and thrombus formation, in part, through the inhibition of PLCγ2–PKC, Akt, and MAPK pathways, without the side effect of bleeding. These findings also indicate that LA may provide a safe and alternative therapeutic approach for preventing thromboembolic disorders such as stroke.
