Authors: Mackert Michael , Guadagno Marie , Lazard Allison , Donovan Erin , Rochlen Aaron , Garcia Alexandra , Damásio Manuel José
Published: December 2016

Pregnancy outcomes in the United States continue to rank among the worst in the developed world. Traditional maternal–child health promotion tends to focus exclusively on women, leaving men out of programs that can affect family health. Scholars advocate including men in prenatal health to reduce maternal and infant mortality and morbidity. This study explored the perceived role of men in prenatal health, the use of an e-health application, and participant-suggested ways of improving the application moving forward. This study interviewed men in a large Southwestern U.S. city with an average age of 26.0 years ( N = 23). The sample was 52% White, 26% Hispanic, 9% Asian, 9% multiracial or other, and 4% Black. Participants were asked about pregnancy health and used a pregnancy-related e-health application on a tablet computer. Participants provided opinions on content, ease of use of tablets, and recommendations for a stronger application. Despite perceived barriers such as time constraints, financial burdens, and an unclear role, men believe it is important to be involved in pregnancy health. Most found the application to contain useful and interesting information. Participants recommended the addition of videos and interactive modules to make the application stronger. This study explored the use of a targeted e-health application to introduce men to prenatal health education. Results indicate men feel favorable to this type of intervention. Additional refinement of the application could include interactive tools or “push content” to further engage men in this important topic.

Published: December 2016

Background

Flow diverter (FD) malapposition is associated with stroke-related complications. We document the use of self-expanding nitinol stents to remove/reduce the ledge of a FD deployed for aneurysm treatment.

Methods

We identified five patients who were treated with the Pipeline embolization device (PED) in conjunction with a Neuroform EZ stent for inadequate wall apposition of the ends of the FD at our institution between May 2014 and July 2015. Among other parameters, angiographic results, cone-beam computed tomography assessment of wall apposition and patient clinical outcome were evaluated.

Results

Incomplete device end apposition was seen in three cases, and precarious positioning of the distal end of the PED over the aneurysm neck was seen in two cases. In all five cases, successful treatment with good wall apposition and proper pinning of the PED distal edge was achieved using an additional Neuroform EZ stent. Appropriate aneurysm neck coverage and flow stagnation was seen in all cases. The combination of high radial outward force and open-cell design permits the Neuroform EZ stent to jail the malappositioned edges of the FD while maintaining good vessel-wall apposition itself and prevent migration of the PED. Short-term follow-up angiography showed device patency and complete aneurysm obliteration in all cases.

Conclusions

Preliminary results of this small case series suggest that the Neuroform EZ stent allows for effective treatment of FD malapposition in selected patients amenable for this endovascular approach. Long-term and larger cohort studies are needed to validate these results.
Nonlinear multiple-input-multiple-output adaptive backstepping control of underwater glider systems
Authors: Cao Junjun , Cao Junliang , Zeng Zheng , Lian Lian
Published: December 2016

In this article, an adaptive backstepping control is proposed for multi-input and multi-output nonlinear underwater glider systems. The developed method is established on the basis of the state-space equations, which are simplified from the full glider dynamics through reasonable assumptions. The roll angle, pitch angle, and velocity of the vehicle are considered as control objects, a Lyapunov function consisting of the tracking error of the state vectors is established. According to Lyapunov stability theory, the adaptive control laws are derived to ensure the tracking errors asymptotically converge to zero. The proposed nonlinear MIMO adaptive backstepping control (ABC) scheme is tested to control an underwater glider in saw-tooth motion, spiral motion, and multimode motion. The linear quadratic regular (LQR) control scheme is described and evaluated with the ABC for the motion control problems. The results demonstrate that both control strategies provide similar levels of robustness while using the proposed ABC scheme leads to the more smooth control efforts with less oscillatory behavior.
The journey of individuation: A Jungian alternative to the theory and practice of leading authentically
Authors: Ladkin Donna , Spiller Chellie , Craze Gareth
Published: December 2016

Along with increasing interest in the concept of ‘authenticity’ as it applies to leadership, critique of dominant authentic leadership theorizing is also on the rise. This paper joins that critique in relation to a key aspect of dominant theorizing: its neglect of the unconscious and its role in shaping one’s experience and behaviour. This oversight results in an unrealistic version of ‘authenticity’ which over-emphasizes pro-social, positive conduct, prescribes components through which authenticity is achieved, and directs individuals to act from an individually determined ‘true self’ rather than recognizing the role that both others and the wider context play in the creation of that self. The notion of ‘mature personhood’, underpinned by Jung’s theory of individuation is offered as an alternative aspirational aim for those wishing to take up the leading role in a way which align what is ‘real’ for them at a given moment within the demands of organizational contexts. Drawing from Jung’s ideas of ‘the shadow’, the ‘centre point’ and ‘the collective’, we theorize an integrated approach to leadership which accounts for unconscious as well as conscious processes, works with less desirable aspects of the self rather than dismissing them, is achieved through reflexive processes rather than prescriptive formulae; and is collectively, rather than individually determined.
Traditional practices and adverse pregnancy outcomes in migrant women
Authors: Morton Adam
Published: December 2016

Traditional practices during pregnancy may lead to adverse outcomes in migrant women. Very little is known regarding the efficacy or safety of many cultural practices during pregnancy, and research is required to address this deficiency in knowledge. Greater awareness of traditional practices by health professionals may result in improved pregnancy outcomes in migrant women.
Interspecific and Intraspecific Variation in Functional Traits of Subtropical Evergreen and Deciduous Broadleaved Mixed Forests in Karst Topography, Guilin, Southwest China

Published: December 2016

Interspecific variation in plant functional traits is the basis of species coexistence in natural ecosystems. However, intraspecific variation is extremely important to community assemblage as well. Here, we quantify leaf trait variation within and across 32 dominant shrub species within two different leaf forms (16 evergreen species and 16 deciduous species) in subtropical evergreen and deciduous broadleaf mixed forest in the Karst topography of Guilin, southwest China. Results showed that leaf area (LA) and leaf thickness (LT) of evergreen species were significantly lower than those of deciduous species, whereas specific leaf areas (SLA) and leaf dry matter content (LDMC) showed the opposite pattern. For SLA and LA, the majority variance was found among species (50.82% vs. 65.01%) and little was found within species (22.98% vs. 27.89%), whereas the largest variation was within species (44.87% vs. 48.2%) with little among species (40.73% vs. 43%) for LDMC and LT. The large variability of LDMC and LT within species may reflect niche differentiation and the importance of intraspecific variation on species coexistence. Our results will help design conservation strategies for this unique subtropical evergreen-deciduous broadleaved forest ecosystem.
The Effect of Growth Hormone on Chondral Defect Repair
Authors: Danna Natalie R. , Beutel Bryan G. , Ramme Austin J. , Kirsch Thorsten , Kennedy Oran D. , Strauss Eric
Published: December 2016

Objective

Focal chondral defects alter joint mechanics and cause pain and debilitation. Microfracture is a surgical technique used to treat such defects. This technique involves penetration of subchondral bone to release progenitor cells and growth factors from the marrow to promote cartilage regeneration. Often this results in fibrocartilage formation rather than structured hyaline cartilage. Some reports have suggested use of growth hormone (GH) with microfracture to augment cartilage regeneration. Our objective was to test whether intra-articular (IA) GH in conjunction with microfracture, improves cartilage repair in a rabbit chondral defect model. We hypothesized that GH would exhibit a dose-dependent improvement in regeneration.

Design

Sixteen New Zealand white rabbits received bilateral femoral chondral defects and standardized microfracture repair. One group of animals ( n = 8) received low-dose GH by IA injection in the left knee, and the other group ( n = 8) received high-dose GH in the same manner. All animals received IA injection of saline in the contralateral knee as control. Serum assays, macroscopic grading, and histological analyses were used to assess any improvements in cartilage repair.

Results

Peripheral serum GH was not elevated postoperatively ( P = 0.21). There was no improvement in macroscopic grading scores among either of the GH dosages ( P = 0.83). Scoring of safranin-O–stained sections showed no improvement in cartilage regeneration and some evidence of increased bone formation in the GH-treated knees.

Conclusions

Treatment with either low- or high-dose IA GH does not appear to enhance short-term repair in a rabbit chondral defect model.
Development of a Cartilage Shear-Damage Model to Investigate the Impact of Surface Injury on Chondrocytes and Extracellular Matrix Wear
Authors: Trevino Robert L. , Pacione Carol A. , Malfait Anne-Marie , Chubinskaya Susan , Wimmer Markus A.
Published: December 2016

Background

Many i n vitro damage models investigate progression of cartilage degradation after a supraphysiologic, compressive impact at the surface and do not model shear-induced damage processes. Models also neglect the response to uninterrupted tribological stress after damage. It was hypothesized that shear-induced removal of the superficial zone would accelerate matrix degradation when damage was followed by continued load and articulation.

Methods

Bovine cartilage underwent a 5-day test. Shear-damaged samples experienced 2 days of damage induction with articulation against polyethylene and then continued articulation against cartilage (CoC), articulation against metal (MoC), or rest as free-swelling control (FSC). Surface-intact samples were randomized to CoC, MoC, or FSC for the entire 5-day test. Samples were evaluated for chondrocyte viability, GAG (glycosaminoglycan) release (matrix wear surrogate), and histological integrity.

Results

Shear induction wore away the superficial zone. Damaged samples began continued articulation with collagen matrix disruption and increased cell death compared to intact samples. In spite of the damaged surface, these samples did not exhibit higher GAG release than intact samples articulating against the same counterface ( P = 0.782), contrary to our hypothesis. Differences in GAG release were found to be due to tribological testing against metal ( P = 0.003).

Conclusion

Shear-induced damage lowers chondrocyte viability and affects extracellular matrix integrity. Continued motion of either cartilage or metal against damaged surfaces did not increase wear compared with intact samples. We conjecture that favorable reorganization of the surface collagen fibers during articulation protected the underlying matrix. This finding suggests a potential window for clinical interventions to slow matrix degradation after traumatic incidents.
Endoscopic ultrasound in gastric cancer staging before and after neoadjuvant chemotherapy. A comparison with PET‐CT in a clinical series

Published: December 2016

Background

Treatment of gastric cancer is based on accurate staging. Emerging methods, such as PET‐CT, are increasingly being used for this purpose. Our aim was to analyze the results of EUS and PET‐CT in staging and restaging our patients with gastric cancer, comparing both of them with the histological results.

Methods

Patients with confirmed gastric cancer were prospectively enrolled. Inclusion criteria for the final analysis included only patients who finally received a surgical resection. All patients underwent preoperative TNM staging by means of EUS and PET‐CT within 21 days prior to the surgical treatment.

Results

A total of 256 patients were included. The overall EUS accuracy for T staging was 78% and 80.2% in restaging. EUS showed its best accuracy when distinguishing T1–T2 tumors vs. T3–T4, with an increased accuracy in restaging. Regarding N staging, the overall accuracy of EUS was 76.2%, and 72.5% for PET‐CT (p  = 0.02). With regards to restaging, accuracy of EUS and PET‐CT for N staging was 88.5% and 69%, respectively, with significant differences (p  < 0.0001).

Conclusions

EUS performed better than PET‐CT in gastric cancer N staging and restaging. EUS accuracy in this setting is still suboptimal and probably more than one single diagnostic procedure should be used.
The machine that ate bad people: The ontopolitics of the precrime assemblage
Authors: Mantello Peter
Published: December 2016

This article examines the “aesthetic” and “prescient” turn in the surveillant assemblage and the various ways in which risk technologies in local law enforcement are reshaping the post hoc traditions of the criminal justice system. The rise of predictive policing and crime prevention software illustrate not only how the world of risk management solutions for public security is shifting from sovereign borders to inner-city streets but also how the practices of authorization are allowing software systems to become proxy forms of sovereign power. The article also examines how corporate strategies and law enforcement initiatives align themselves through media, connectivity, and consumer-oriented opt-in strategies that endeavor to “mold” and “deputize” ordinary individuals into obedient and patriotic citizens.
Autophagy, a key mechanism of oncogenesis and resistance in leukemia
Authors: Auberger Patrick , Puissant Alexandre
Published: December 2016

Autophagy is a lysosomal pathway involved in degradation of intracellular material. It appears as an adaptation mechanism that is essential for cellular homeostasis in response to various stress conditions. Over the past decade, many studies have linked alteration of autophagy with cancer initiation and progression, autoimmune, inflammatory, metabolic, and degenerative diseases. This review highlights recent findings on the impact of autophagy on leukemic transformation of normal hematopoietic stem cells and summarizes its role on leukemic cell response to chemotherapy.
LW-AFC, a new formula derived from Liuwei Dihuang decoction, ameliorates behavioral and pathological deterioration via modulating the neuroendocrine-immune system in PrP-hAβPPswe/PS1ΔE9 transgenic mice
Authors: Wang Jian-Hui , Lei Xi , Cheng Xiao-Rui , Zhang Xiao-Rui , Liu Gang , Cheng Jun-Ping , Xu Yi-Ran , Zeng Ju , Zhou Wen-Xia , Zhang Yong-Xiang
Published: December 2016

Background

Accumulating evidence implicates the neuroendocrine immunomodulation (NIM) network in the physiopathological mechanism of Alzheimer’s disease (AD). Notably, we previously revealed that the NIM network is dysregulated in the PrP-hAβPPswe/PS1ΔE9(APP/PS1) transgenic mouse model of AD.

Methods

After treatment with a novel Liuwei Dihuang formula (LW-AFC), mice were cognitively evaluated in behavioral experiments. Neuron loss, amyloid-β (Aβ) deposition, and Aβ level were analyzed using Nissl staining, immunofluorescence, and an AlphaLISA assay, respectively. Multiplex bead analysis, a radioimmunoassay, immunochemiluminometry, and an enzyme-linked immunosorbent assay (ELISA) were used to measure cytokine and hormone levels. Lymphocyte subsets were detected using flow cytometry. Data between two groups were compared using a Student’sttest. Comparison of the data from multiple groups against one group was performed using a one-way analysis of variance (ANOVA) followed by a Dunnett’s post hoc test or a two-way repeated-measures analysis of variance with a Tukey multiple comparisons test.

Results

LW-AFC ameliorated the cognitive impairment observed in APP/PS1 mice, including the impairment of object recognition memory, spatial learning and memory, and active and passive avoidance. In addition, LW-AFC alleviated the neuron loss in the hippocampus, suppressed Aβ deposition in the brain, and reduced the concentration of Aβ1–42in the hippocampus and plasma of APP/PS1 mice. LW-AFC treatment also significantly decreased the secretion of corticotropin-releasing hormone and gonadotropin-releasing hormone in the hypothalamus, and adrenocorticotropic hormone, luteinizing hormone, and follicle-stimulating hormone in the pituitary. Moreover, LW-AFC increased CD8+CD28+T cells, and reduced CD4+CD25+Foxp3+T cells in the spleen lymphocytes, downregulated interleukin (IL)-1β, IL-2, IL-6, IL-23, granulocyte-macrophage colony stimulating factor, and tumor necrosis factor-α and -β, and upregulated IL-4 and granulocyte colony stimulating factor in the plasma of APP/PS1 mice.

Conclusions

LW-AFC ameliorated the behavioral and pathological deterioration of APP/PS1 transgenic mice via the restoration of the NIM network to a greater extent than either memantine or donepezil, which supports the use of LW-AFC as a potential agent for AD therapy.
A novel method for estimation of remaining oil saturations in water-flooded layers
Authors: Yan Weichao , Sun Jianmeng , Zhang Jinyan , Golsanami Naser , Hao Shuyan
Published: December 2016

After long-term production by water injection, the conductivity features of oil reservoirs are changed, leading to difficulties in calculating remaining oil saturation by traditional well-logging techniques. There are some specific phenomena relating to petrophysical properties in water-flooded layers, and a deep investigation of them could help us understand resistivity changes of rocks during the water-injection process. We compared traditional mixed-fluid resistivity methods and determined their drawbacks. In addition, we revised the theoretical models and came up with a novel method to calculate mixed-fluid resistivity. The displacement process was divided into three stages: non-water-flooded stage, low and medium water-flooded stage, and high water-flooded stage. To study the relationships between rock resistivities and water saturations when injecting fresh-/saltwater, we used digital rock numerical methods. We first constructed 3D digital rock models based on the process-based method, and then we obtained oil and water distributions in the pore space by the pore morphology method. When resistivities of every component in digital rock models were assigned, rock resistivities could be calculated in different water saturations by the finite-element method. We found that in the case of freshwater injection, the relationship between water saturations and rock resistivities formed an S-shaped curve, but in the case of saltwater injection, if the injection water salinity was higher, the rock resistivity would be decreased by increasing the water saturation. In different rock heterogeneity and wettability conditions, these curves showed similar shapes and trends. Combined with resistivity logging data, this novel approach was used in the interpretation of a real oil well. Compared with the existing models in the interpretation practices, this new model better matched the real-field saturations and improved the accuracy of saturation interpretation in the studied water-flooded oil reservoir.
Is the WTO Passé?
Authors: Bagwell Kyle , Bown Chad P. , Staiger Robert W.
Published: December 2016

The WTO has delivered policy outcomes that are very different from those likely to emerge out of the recent wave of preferential trade agreements (PTAs). Should economists see this as an efficient institutional hand-off, where the WTO has carried trade liberalization as far as it can manage, and is now passing the baton to PTAs to finish the job? We survey a growing economics literature on international trade agreements and argue on this basis that the WTO is not passé. Rather, and subject to some caveats, our survey of research to date suggests that the WTO warrants strong support while a more cautious view of PTAs seems appropriate. (JEL F13, F14, K33, N70)
Executive Compensation: A Modern Primer
Authors: Edmans Alex , Gabaix Xavier
Published: December 2016

This article studies traditional and modern theories of executive compensation, bringing them together under a simple unifying framework accessible to the general-interest reader. We analyze assignment models of the level of pay, and static and dynamic moral-hazard models of incentives, and compare their predictions to empirical findings. We make two broad points. First, traditional theories find it difficult to explain the data, suggesting that compensation results from “rent extraction” by CEOs. However, more modern “shareholder value” theories, that arguably better capture the CEO setting, do deliver predictions consistent with observed practices, suggesting that these practices need not be inefficient. Second, seemingly innocuous features of the modeling setup, often made for tractability or convenience, can lead to significant differences in the model's implications and conclusions on the efficiency of observed practices. We close by highlighting apparent inefficiencies in executive compensation and additional directions for future research. (JEL G38, M12, M48, M52)

Este documento refere-se aos primeiros resultados do projeto de pesquisa intitulado “Acumulação de Capacidades Tecnológicas e Fortalecimento da Competitividade Industrial no Brasil: Análise Empírica e Recomendações Práticas para Políticas Públicas e Estratégias Empresariais”. No estudo introdutório aqui reportado buscou-se traçar um panorama sobre a questão da competitividade e da inovação, situando o Brasil de hoje em relação ao seu próprio passado e ao contexto internacional. É um pano de fundo inicial do projeto, e a base para se começar o mapeamento das vantagens e desvantagens competitivas das empresas e de setores industriais brasileiros.Na etapa de desenvolvimento em que se encontra o Brasil, o papel da inovação em conceito amplo, que não se restringe à alta tecnologia, é fundamental. Depois de um período de crescimento aceitável (mas insuficiente para produzir convergência com o mundo desenvolvido) entre 2000 e 2010, a produtividade do trabalho e a produtividade total dos fatores (PTF) desaceleram-se nos anos mais recentes. Os indicadores internacionais de competitividade confirmam as dificuldades da economia nacional, com destaque para as áreas ligadas à inovação. O fechamento da economia, que isola as empresas brasileiras das cadeias globais de valor e as protege da pressão competitiva externa, piora esse quadro.A esse respeito, para o Brasil superar a chamada armadilha de renda média e voltar a crescer em um ritmo suficiente para convergir para o padrão socioeconômico das economias avançadas, é fundamental fortalecer a competitividade, o que depende de restabelecer um ritmo vigoroso de elevação da produtividade e desenvolvimento de capacidades tecnológicas inovadoras, em nível de empresas e indústrias.

O desenvolvimento industrial e tecnológico é um dos fatores decisivos para que os países avancem para a categoria de alta renda per capita. Não se trata de uma panaceia, mas a história ensina que nações que se desenvolveram industrialmente, por meio da acumulação de capacidades tecnológicas para inovação, também obtiveram significativo desenvolvimento socioeconômico. Tornaram-se países de alta renda, transformaram-se em líderes no mercado global e em fornecedores de tecnologia para vários tipos de indústria2.Nesse sentido, este documento é parte integrante de um projeto de pesquisa mais amplo sobre o tema da acumulação de capacidades tecnológicas e competitividade industrial no Brasil, que examinou alguns setores industriais, entre eles o sucroenergético.

Η συγκεκριμένη μελέτη επανεξετάζει την έννοια της δημιουργικότητας στο πλαίσιο της προσχολικής εκπαίδευσης αναδεικνύοντας το νόημά της στο πλαίσιο του «ελεύθερου» παιχνιδιού στο νηπιαγωγείο υπό το πρίσμα της κοινωνιο-πολιτισμικής θεωρίας και της θεώρησης των παιδιών ως δρώντων προσώπων στην συνδιαμόρφωση της καθημερινής τους εμπειρίας (νέα κοινωνιολογία της παιδικής ηλικίας). Η δημιουργικότητα έχει κυρίως συνδεθεί στις μέχρι τώρα έρευνες με τη γνωστική ικανότητα που συνδέεται με συγκεκριμένες ποιότητες της σκέψης όπως η παραγωγή νέων ιδεών, η πρωτοτυπία και η ευελιξία κατά τη διάρκεια επίλυσης προβλημάτων. Στο πλαίσιο της κοινωνιο-πολιτισμικής θεωρίας η δημιουργικότητα των παιδιών δεν αντιμετωπίζεται στην παρούσα εργασία σαν ατομικό χαρακτηριστικό ορισμένων παιδιών αλλά πλαισιώνεται ως αποτέλεσμα των αλληλεπιδράσεων των παιδιών μεταξύ τους και με το εκπαιδευτικό περιβάλλον κατά τις οποίες τα παιδιά κατασκευάζουν δικά τους ενδιαφέροντα, δραστηριότητες με νόημα γι’ αυτά και διαπραγματεύονται τους κανόνες και τα όρια που περιορίζουν τη δράση τους. Υπό αυτή την έννοια, δημιουργικότητα θεωρείται η ικανότητα των παιδιών να διαμορφώσουν το πλαίσιο της δράσης τους αναλαμβάνοντας πρωτοβουλίες, επιλέγοντας λύσεις και τρόπους αντίστασης στις ενήλικες επιλογές, με τρόπο που εξυπηρετεί τις επιθυμίες τους στο παιχνίδι. Στο πλαίσιο της νέας κοινωνιολογίας της παιδικής ηλικίας αναγνωρίζεται η ικανότητα των παιδιών να συμμετέχουν στη λήψη αποφάσεων και να επηρεάζουν το περιβάλλον που μεγαλώνουν. Σε αυτό το θεωρητικό πλαίσιο η συγκεκριμένη έρευνα μελετά τους τρόπους με τους οποίους τα παιδιά μπορεί να είναι δημιουργικά στη διάρκεια του ελεύθερου παιχνιδιού αλλά και το πώς οι αξίες, ο τρόπος οργάνωσης της εκπαιδευτικής διαδικασίας και οι κανόνες της τάξης μπορούν να παρέμβουν στις ευκαιρίες που έχουν τα παιδιά να είναι δημιουργικά στο παιχνίδι τους. Η συλλογή δεδομένων βασίστηκε σε επιτόπιες παρατηρήσεις και συνεντεύξεις με τα παιδιά και τις εκπαιδευτικούς σε δύο τάξεις νηπιαγωγείου. Τα αποτελέσματα της έρευνας έδειξαν ότι η δημιουργικότητα των παιδιών εκδηλώνεται κατά τις προσπάθειες των παιδιών να αλλάξουν το πλαίσιο του παιχνιδιού (χρόνος, χώρος, κανόνες, σενάρια) είτε μέσω της προσαρμογής στους κανόνες των ενηλίκων ή μέσα από τη δόμηση νέων νοημάτων και ενδιαφερόντων, τρόπων και δραστηριοτήτων. Η έρευνα αυτή καταλήγει με προτάσεις για εκπαιδευτικούς σε σχέση με το πώς να αναγνωρίζουν τη δημιουργικότητα των παιδιών και πώς να υποστηρίζουν σχετικές ευκαιρίες για την ανάπτυξή της.

Στη 2η πειραματική ομάδα τα ίδια μαθησιακά αντικείμενα εντάχθηκαν στο σχολικό εκπαιδευτικό υλικό, ενώ στη 3η ομάδα ελέγχου δεν εφαρμόστηκε καμία πειραματική παρέμβαση. Τα αποτελέσματα αναδεικνύουν τη θετική συσχέτιση ανάμεσα στη συχνότητα χρήσης του online εκπαιδευτικού υλικού της εξ αποστάσεως εκπαίδευσης, της ακαδημαϊκής επίδοσης των μαθητών και της ικανοποίησης που αντλούν. Παράλληλα, διαπιστώνεται η αποτελεσματικότητα των μαθησιακών αντικειμένων του Φωτόδεντρου ως εργαλείων εμπλουτισμού του εκπαιδευτικού υλικού της εξ αποστάσεως εκπαίδευσης, που υπολείπεται όμως σε σύγκριση με την αντίστοιχη της συμβατικής.

Published: December 2016

Today, during the ‘fourth industrial revolution’ which is led by the Internet and the digital ecosystem it creates, schools are expected to achieve the development of not only the functional skills of literacy and numeracy but also of general knowledge. The apparent inadequacy of the standardized education system to respond to the needs and interests of 21st-century students urges researchers to adopt new forms of teaching as meaningful and high-quality teaching requires a more active use of innovative educational methods and tools. With the rapid development of IT globally, there is a tendency to utilize the capabilities of e-learning as a mode of distance learning since itcan function both independently of and in conjunction with conventional teaching. The varied applications of Web 2.0 tools create new possibilities in the educational sector. It provides the ability to develop innovative educational methods that transform students from passive recipients of information to knowledge creators through an active involvement in the learning process often within a modern interactive environment. This study presents the results of the implementation of a teaching intervention, with the use of a flexible and student-centered web system developed and used as complementary to the ‘Research Project’ course during the first term of the 2015-2016 school year. The ultimate goal of this effort was to highlight and consequently incorporate the use of a digital platform for student conferences which we implemented in schools as a means to research, learning, and skill development. The students had the opportunity to participate in a digital community which employed distance learning tools for communication, cooperation, and learning during a digital conference in which they had leading roles as writers and reviewers. The initial results of the pilot study indicated that the use of the digital platform increased the interest of students, supported the development of various skills and contributed to the overall improvement of the teaching and learning process.

Published: December 2016

Quantitative cross-linking/mass spectrometry (QCLMS) probes protein structural dynamics in solution by quantitatively comparing the yields of cross-links between different conformational statuses. We have used QCLMS to understand the final maturation step of the proteasome lid and also to elucidate the structure of complement C3(H2O). Here we benchmark our workflow using a structurally well-described reference system, the human complement protein C3 and its activated cleavage product C3b. We found that small local conformational changes affect the yields of cross-linking residues that are near in space while larger conformational changes affect the detectability of cross-links. Distinguishing between minor and major changes required robust analysis based on replica analysis and a label-swapping procedure. By providing workflow, code of practice and a framework for semi-automated data processing, we lay the foundation for QCLMS as a tool to monitor the domain choreography that drives binary switching in many protein-protein interaction networks.

Criteria for Identifying Wound Infection
Authors: Cutting K.F. , Handing CG.
Published: December 2016

Criteria used to identify infection may often be restricted to the presence of pus, or pus with inflammation1. Traditional criteria have been used in many surveys and their advantage is that they are simple, reproducible and easily recognised by different observers. However, identification of infection may be difficult in some circumstances, and identifying patients who are likely to develop infection is rare.

Spectrum regulation for mid-infrared ultrafast pulses via a time-synchronization aperiodically poled LiNbO3
Authors: Zhong Haizhe , Qin Fen , Yang Jianlong , Zhang Lifu , Xu Changwen , Li Ying , Fan Dianyuan
Published: December 2016

Restricted to temporal separation during the coupled-waves interaction, aperiodically quasi-phase-matching (QPM) nonlinear crystals are primarily implemented for prechirped pulses, showing limited applications in ultrafast temporal scale. Under the proposed time-synchronization framework, pump and signal waves travel with identical group-velocity, which permits sustaining energy transfer in long aperiodically poled LiNbO3 crystals (APPLN) even with ultrafast pulse duration. With the help of this structure, adiabatic frequency conversion shows extra advantages compared with the common cases, which enables lower stretching ratio and smoother gain spectrum. Focusing on the typical mid-infrared wavelength of ~3 μm, we numerically study the potential performance of APPLN with chirp-free ultrabroad interacting waves. In contrast to the spectral shift and conversion efficiency degradation presented by its traditional Type-0 QPM counterpart, the proposed design demonstrated impressive ability to obtain arbitrary spectrum via a simple femtosecond OPA/OPO. Peculiarly, the QPM chirp rate sign plays a significant role to the output spectrum, and a positive chirp rate is preferential in delivering a bandwidth-controllable spectrum. The proposed design provides a promising technical route to achieve spectrum manipulation in ultrafast temporal scale.

Published: December 2016

The use of an optical fiber as a real-time distributed microphone is demonstrated employing a phase-OTDR with direct detection. The method comprises a sample-and-hold circuit capable of both tuning the receiver to an arbitrary section of the fiber considered of interest and to recover in real-time the detected acoustic wave. The system allows listening to the sound of a sinusoidal disturbance with variable frequency, music and human voice with ~60 cm of spatial resolution through a 300 m long optical fiber.
Surface plasmon dispersion in hexagonal, honeycomb and kagome plasmonic crystals

Published: December 2016

We present a systematic experimental study on the optical properties of plasmonic crystals (PlC) with hexagonal symmetry. We compare the dispersion and avoided crossings of surface plasmon modes around the Γ-point of Au-metal hole arrays with a hexagonal, honeycomb and kagome lattice. Symmetry arguments and group theory are used to label the six modes and understand their radiative and dispersive properties. Plasmon-plasmon interaction are accurately described by a coupled mode model, that contains effective scattering amplitudes of surface plasmons on a lattice of air holes under 60°, 120°, and 180°. We determine these rates in the experiment and find that they are dominated by the hole-density and not on the complexity of the unit-cell. Our analysis shows that the observed angle-dependent scattering can be explained by a single-hole model based on electric and magnetic dipoles.

Published: December 2016

Todas las lenguas presentan formas de marcar el foco para diferenciarlo de los patrones no-marcados. La prosodia constituye una herramienta esencial para la producción y percepción del foco oracional. El objetivo del presente trabajo es analizar la identificación del foco y sus asociaciones con la percepción de la prominencia. Se realizó un experimento con 540 oraciones afirmativas e interrogativas, y con distintas variaciones focales (sujeto, predicado y foco neutro). Siete hablantes del español definieron el tipo de oración, identificaron el tipo de foco y marcaron el nivel de prominencia para cada una de las sílabas de la oración. Los resultados muestran que la totalidad de los hablantes definen de manera correcta el tipo de oración. Sin embargo, un alto porcentaje de evaluadores percibió con foco en el predicado a las oraciones emitidas con foco neutro. Además, se observó que las curvas de prominencia tonal no siempre correlacionaron con la producción de foco.
