From Leaf to Label: A robust automated workflow for stomata detection
Authors: Meeus Sofie , Wyffels Francis , Van den Bulcke Jan 
Published: June 2019

Leaf stomata are microscopic pores on the leaves of plants which control the balance between water loss and CO2 uptake by the plant. As plants adapt their stomatal traits in response to environmental parameters such as water availability, temperature and atmospheric carbon dioxide concentrations, stomatal size and density of preserved leaves have allowed for reconstruction of past climates. Stomata serve as ‘gates’ between deep-soil water reservoirs and the atmosphere and are a key determinant of transpiration in models for operational predictions of the near-climate. It is well known that stomatal size and density vary widely across plant species and even though efforts have mapped stomatal behavior globally, more detail is needed as including more interspecific trait variation in climate models could significantly reduce the error in model predictions. Despite their important function, no standardized methodology has yet been described to measure stomatal traits which is widely considered to be labour-intensive and time-consuming and to this day mostly performed manually.
Herbaria contain a treasure of unique ecological data covering large temporal scales. We used the African Herbarium of Meise Botanic Garden which contains over 1.2 million African specimens with a very good coverage of the Congo Basin (dating back to 1880) to develop a workflow for extracting stomatal trait data starting from the herbarium specimen, involving the automatic detection of stomata using a deep learning approach. The purpose of developing this workflow is to generate a large amount of data on stomatal traits on an easy, cost- and time- efficient manner. Here, we will present the leaf-to-label workflow and demonstrate how it was used to study the effect of global change on leaf adaptation in central African rainforest over the past 100 years.

Published: June 2019

Background:
Nurses are in a privileged position to detect environmental risks among children. The objective was to determine attitudes, knowledge, and skills related to children's environmental health in undergraduate nursing students.

Method:

A cross-sectional study was designed in eight universities (
n
= 2,462) from September 2017 to June 2018. Descriptive values and multivariate analysis of variance were calculated using three questionnaires.

Results:

Of the total 2,462 students in the sample, 2,155 had a good attitude regarding addressing children's environmental health problems, 501 had good knowledge, and 1,162 had good skills. Students who had attended a session on sustainability more than 3 months prior had a better attitude (9.93%), knowledge (11.16%), and skills (3.82%). Second course students and men had better environmental competency (
p
< .001).

Conclusion:

Undergraduate nursing students have good attitudes; however, they lack knowledge and skills. There is a need to include children's environmental health in nursing curricula.

The contribution of hyperinsulinemia to the hyperandrogenism of polycystic ovary syndrome
Authors: Pateguana Nadia B. , Janes Alvin 
Published: June 2019

Background: Polycystic Ovary Syndrome (PCOS) is a very common endocrine disorder of young women.Aim: The proper treatment of PCOS requires a thorough understanding of the underlying cause of disease. In this article, we review the extent to which hyperinsulinemia contributes to the development of PCOS.Setting: The goal of this review was to assess the current literature on the contribution of hyperinsulinemia to the hyperandrogenism of polycystic ovary syndrome in hopes of promoting future research and advancements in clinical treatments for women with PCOS focusing on this major contributing factor, hyperinsulinemia.Method: A review of published peer-reviewed literature was conducted by searching the keywords.Results: Excessive insulin causes both the overproduction of testosterone and decreased sex hormone binding globulin (SHBG) levels seen in PCOS, both of which collaborate in creating an increased testosterone effect.Conclusion: The majority of research and evidence shows that the hyperandrogenism of PCOS is likely caused by hyperinsulinemia. Yet the conventional treatment of hyperandrogenic symptoms in women with PCOS is not directed towards correcting this underlying hyperinsulinemia. Further research is needed to assess how the treatment of the hyperinsulinemia through lifestyle would compare to the current treatment of hyperandrogenemia through testosterone-lowering drugs.

Abstract

Growing up in complex reality: the unique contribution of pedagogical science in the Netherlands

The inception of the discipline of pedagogical science in the Netherlands was exactly one hundred years ago in 2018. After a brief description of the history of pedagogy, several domains of the current field of pedagogy, in particular child and family studies and clinical child and family studies are highlighted. Next, the interrelations between pedagogy, psychology and psychiatry using the bio-psycho-social model and the socio-ecological model are described. Pedagogical science is an empirically-normative, performance-centered, and integrative science that unites the broad spectrum of behavioural sciences. With this unique combination, pedagogical science helps to answer scientific, clinical, and societal questions to help children reach their full potential.

Research of quantitative trait loci (QTL) for macronutrient accumulation in soybean seed is limited. Therefore, the objective of this research was to identify QTL related to macronutrients (N, C, S, P, K, Ca, and Mg) in seeds in 92 F5:7 recombinant inbred lines (RILs) developed from a cross between MD 96-5722 (MD) and Spencer using a total 5,376 Single Nucleotide Polymorphism (SNP) markers. A genetic linkage map based on SNP markers was constructed using the Illumina Infinium SoySNP6K BeadChip Array. The RILs were genotyped using 537 polymorphic, reliably segregating SNP markers. A total of 8 QTL for K (qPOT001-qPOT008) were identified on LGs D1b (Chr 1), N (Chr 3), A1 (Chr 5), O (Chr 10), F (Chr 13), B2 (Chr 14), and J (Chr 16). Four QTL for Mg (qMAG001-qMAG004) were identified on LGs N (Chr 3), A1 (Chr 5), J (Chr 16), and G (Chr 18). One QTL for P (qPHO001), one for C on LG J (Chr 16), one for N (qNIT001) and S (qSUL001) on the same LG J (Chr 16), and one QTL for Ca (qCAL001) on LG G (Chr 18). K and Mg QTL were clustered together on LG A1 (Chr 5) with a peak position of 9.50 cM and LOD support interval of 8.50-9.50 cM. Similar observation was noticed for P, K, Mg, C, N, and S, where the QTL were clustered on LG J (Chr 16) with peak position of 11 cM for K, P, and S, and 10 cM for C and N, and 12 cM for Mg. The LOD support intervals for all these clustered QTL were between 8.90 and 12.30 cM. The QTL clustering of these nutrients suggests possible common physiological and genetic relationships, suggesting possible similar metabolic processes and pathways for these nutrients. The inverse relationships between N:S ratio and all nutrients suggest possible use of N:S ratio as a measure for higher nutrients accumulation in seed. Since most of QTL identified in this study were not previously reported, this research will further help breeders to improve nutrient accumulation in seeds and contribute to our understanding of the physiological and genetic bases of seed nutrition quality.

For more than 30 years, institutions funded by NIH had less than an impressive record for achieving diversity in the bio- medical workforce. To address this concern, NIH recently implemented a series of bold initiatives to bridge the gaps in NIH training programs to further promote diversity. However, critical to the success of these initiatives is the timely report- ing, from institutions with large diverse populations such as HBCUs, of evidence-based practices, strategies, and interven- tions for training and transitioning individuals underrepre- sented (UR) in the biomedical sciences from baccalaureate to Ph.D. degree programs. To this end, the purpose of this study is to evaluate the 10-year success of the NIH-funded MBRS Fayetteville State University (FSU) Research Initiative for Scientific Enhancement (FSU-RISE) program for training and subsequent transitioning of UR students from the baccalaure- ate degree into advanced degree programs in the biomedical sciences. We hypothesized that the FSU-RISE program would significantly increase the number of well-prepared under- graduate UR biology and chemistry students who would graduate and transition into advanced degree programs in the biomedical sciences. This article provides evidence-based findings on practices, strategies and interventions for prepar- ing UR individuals from a Historically Black College and Uni- versity (HBCU) for successful entry into Ph.D. programs
Act for Your Life: Widows in Vrindavan
Authors: Ganapathy Radhica 
Published: June 2019

Abstract
To draw further attention to the notion of the physical body as a contested space, I observed widows in Vrindavan, India. Widows relocate to Vrindavan for a multitude of reasons, but, given certain performative theories of identity, this relocation marks the beginning of a distinct performance of widowhood, involving clothing, religious practices, commitments to religious institutions, and begging. Vrindavan's widows' survival depends on their performance of widowhood.
Can't Buy Me Love: Commodification and Redemption in F. Scott Fitzgerald's “The Popular Girl”
Authors: Senn Farrah R. 
Published: June 2019

AbstractF. Scott Fitzgerald's popular magazine fiction story “The Popular Girl” mirrors in its commodification of characterization, language, relationships, and plot points the same commodification in the author's career, personal life, and national societal experiences in the jazz age. However, the story's emphasis on social and cultural capital—and that of the author and his country—cannot be fully understood through discussion centered strictly on commodification/consumerism or social class alone. Pierre Bourdieu's theory of the interplay of economic and cultural capital can be applied to explain the actions of the main character, Yanci, and by extension Fitzgerald's and 1920s America.
Things of the World: Migration, Presence, and the Arts of Presencing
Authors: Cintrón Ralph , Schneider Jason 
Published: June 2019

ABSTRACTThis essay argues for the value of presence as rhetorical heuristic. Beginning with the philosophical tradition, the authors establish a long-standing interest in presence or isness, understood as the thing-itself outside subjectivity. We then trace how rhetorical theorists including Aristotle, Quintilian, and Perelman have privileged isness as a baseline for true conviction, positioning rhetoric as an effort to imitate material proofs. Such views highlight the tension between presence (things of the world in their isness) and the arts of presencing (the capacity of words and symbols to shape an isness), suggesting a generative frame for analysis. To demonstrate, we examine global migration. Drawing on ethnographic fieldwork among undocumented migrants, we posit that these individuals' paradoxical experiences of bodily presence but legal absence reveal a fraught interplay among rhetoric, state power, and competing notions of truth. However, immigration is only a case study; presence is a much more widely applicable heuristic.
Dwelling Narratively: Exploring Heideggerian Perspectives in the Narrative Paradigm
Authors: Qvortrup Mads , Nielsen Esben Bjerggaard 
Published: June 2019

ABSTRACTWalter Fisher's narrative paradigm has sparked intense debate about the role of narratives in rhetorical scholarship. The theory has subsequently been followed up by numerous criticisms and revisions. This article argues that especially the latter can benefit from a complementary phenomenological perspective that Fisher himself placed within the original paradigm. Through the Heideggerian concepts of building and dwelling, rhetoric within the narrative paradigm may be seen as a primary means for engaging with both individual and communal goals and exigencies, providing a more nuanced account for how people care for and act on the narratives in their lives.

Authors: S Shuna , L Ping , W Junfei 
Published: June 2019

Objective: To explore the expression levels of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) in ascites in ovarian tumor and provide a theoretical basis for the diagnosis and prognosis evaluation of ovarian cancer ascites.Methods: ELISA was used to detect the levels of MMP-2 and MMP-9 in ascites samples from 73 cases of patients with malignant ovarian tumor, and RIA was used to detect the expression level of CA125 in the serum in these patients.Results: The expression levels of MMP-2 and MMP-9 in ascites in malignant ovarian tumor were higher than those in ascites in benign ovarian tumor (t = 8.08, 10.39, p < .01), and the difference was of statistical significance. The expression levels of MMP-2 and MMP-9 in patients with stage III and IV malignant ovarian tumors were higher than those in patients with stage I and II malignant ovarian tumors, and the difference was statistically significant (t = 2.75, 2.75, p < .05). There was no statistically significant difference in the expression levels of MMP-2 and MMP-9 among the patients with different pathological types, different histological grades, lymph node metastasis or not, different ascites volumes and different residual lesions (p > .05). The sensitivities of detecting MMP-2 and MMP-9 in ascites were 76.0% and 88.0%, respectively, which were significantly higher than those of ascites cytological examinations (χ2 = 4.61, 12.74, p < .05), but in comparison with serum CA125, there was no statistically significant difference (p > .05). The specificities of detecting MMP-2 and MMP-9 in ascites were 78.3% and 82.6%, respectively, which were significantly lower than those of ascites cytological examinations (χ2 = 5.61, 4.38, p < .05), but in comparison with serum CA125, there was no statistically significant difference (χ2 = 1.64, 2.68, p < .05).Conclusions: The levels of MMP-2 and MMP-9 in ascites may be markers for the differential diagnosis of benign and malignant ovarian lesions, and they are related to the prognosis in patients with malignant ovarian tumors.

Este trabajo se realizó con el objetivo de analizar las redes de apoyo de jóvenes universitarios y mostrar que la feminización del cuidado, arraigada en nuestra cultura, induce patrones en la dinámica del apoyo social de esta población. Es un estudio cuantitativo y transversal que se llevó a cabo con jóvenes universitarios, que tenían entre 18 y 30 años de edad y que durante el 2016 se encontraban cursando una carrera en el Centro Universitario de la Ciénega de la Universidad de Guadalajara. La recogida de la información se efectuó mediante la aplicación de en línea basado en la rejilla de dispersión de dependencias de Kelly. El análisis de concentración -dispersión se desarrolló mediante POSAC (Partial Order Scalogram Analysis)y SPSS. En los resultados se encontró que la madre es la principal provedora de apoyo para el 94% de los participantes. Mientras que otras personas de la red familiar, como los abuelos, ofrecen poco apoyo. Otro de los hallazgos es que los tíos se colocan como fuente de apoyo relevante, aún más que el propio padre, quien tan solo aparece como figura importante para el apoyo instrumental, asociado a requerimientos económicos.

Authors: Frivaldsky Michal , Morgos Jan , Kanovsky Andrej 
Published: June 2019

Dual interleaved LLC resonant converter with half bridge topology of main circuit characterized by high switching frequency (500 kHz), high power density (60 W/inch3) and high efficiency (above 96 %) over entire operational range (20 %–100 %) is described. Focus was given on the practical design of power converter, which will be able to fulfil requirements on wide load range operation characterized by upcoming normative. Since proposed topology is based on dual interleaved LLC converter, the resonant component´s critical tolerance was also investigated to secure reliable and optimal operational point. Consequently, proposals for elimination of intolerance negative impact are also described. The results of theoretical analysis were verified directly through experimental measurements. Experimental results are finally compared with upcoming industrial standard 80 Plus Titanium.

Video Viewing Patterns Using Different Teaching Treatments: A Case Study Using YouTube Analytics
Authors: Walsh John N. , O'Brien Michael P. , Slattery Darina M. 
Published: June 2019

This study explores the viewing patterns of 17 instructional videos in both a traditional and flipped classroom environment by 732 business students taking an IT-related module. While previous work has concentrated mainly on outputs(e.g. student satisfaction/results), this study focuses on how the nature of students’ interactions with videos can be determined through a deep analysis of analytics data. The main findings show that there were less interactions with the instructional videos in the flipped classroom environment compared to the traditional environment, and that videos were used more as a revision aid prior to exams (in both environments) than as an ongoing support to develop skills during term. Implications of this study include the need for regular monitoring of how instructional videos are being used during termand the importance of undertaking a deeper analysis of analytics data as the initial summary data may be misleading.
Effects of Tin Mine Tailings on the Growth and Development of Common Bean (Phaseolus vulgaris L.) in Jos, Nigeria
Authors: Ali A. D. , Habila S. , Isiwu N. C. , Osaji K. J. , Nyam D. D. 
Published: June 2019

Aims: To study the effects of mine tailings on the growth and yield of two genotypes of common bean (Phaseolus vulgaris L.).
Study Design: The experiment was laid in a Randomized Complete Block Design (RCBD) with four treatments, two blocks and each block was replicated three times.
Place and Duration of Study: Botanical Garden, Department of Plant Science and Biotechnology University of Jos, Plateau State, Nigeria during the rainy season in a field experiment in 2014.
Methodology: The mine tailings combinations include four different additions mine tailings soil {(T0) 0 kg as control, (T1) 2 kg, (T2) 3 kg, (T3) 4 kg} and the respective mine tailings soils were added to 6.3 kg of normal soil. Two common bean accessions were used (Cranberry-G1 and Pinto-G2), which gave the total of eight treatment combinations (T0G1, T0G2, T1G1, T1G2, T2G1, T2G2, T3G1, T3G2).
Results: The control recorded significant higher mean plant height (cm), number of leaves and number of trifoliate leaves, number of pods and number of seeds per pod in both genotypes for all the different weeks after planting (WAP). A significant decrease in plant height, number of trifoliate leaves, number of leaves per plant, number of pods and number of seeds per pod in both genotypes were observed with increased levels of mine tailings. There was a significant increase in time to 50% flower and 50% pod production (P = 0.01) over the control which increased with increasing levels of mine tailings. The genotypes exhibited no significant difference (P = 0.05) for most traits accessed, except for number of pod per plant. It is evident from the findings that Cranberry is more tolerant to heavy metals contamination in soil, perhaps may be more suitable for planting in such mining soils.
Conclusion: The study showed that inclusion of mine tailings had detrimental effect on both the growth and yield of common bean.
Controllable Polarization Rotator with Broadband High Transmission Using All‐Dielectric Metasurfaces

Published: June 2019

AbstractIn recent years, how to fully manipulate the polarization state of linearly polarized (LP) light has become an emerging research hotspot in the region of photonics. Here, a novel alternative approach based on all‐dielectric metasurfaces to realize and control the polarization state of light with broadband and high transmission is theoretically and numerically investigated. In contrast with the polarization rotation mechanism of non‐chiral metasurfaces, the proposed configuration can be illustrated by the Jones matrix in a theoretical analysis. The proposed design is based on multi‐conversion of the incident linearly polarized light in a double‐layer quarter‐wave plate structure. Through an elaborate design of the structural units, a one‐layer quarter‐wave plate structure can convert a linearly polarized light to a circularly polarized state. An arbitrary polarization rotation with high efficiency (>88%) and broadband (approximately equal to the bandwidth of quarter‐wave plate) can be achieved through the collective effect of the two quarter‐wave plates. The proposed approach based on all‐dielectric metasurfaces exhibits the capacity of arbitrarily manipulating the polarization states, which can facilitate future applications in photonics.
