STAYING AFLOAT VIA GUANXI: STUDENT NETWORKS, SOCIAL CAPITAL AND INEQUALITY IN CHINESE ADULT HIGHER EDUCATION

ABSTRACT This study illuminates students’ purposive cultivation of guanxi, or social networks based on continuous exchange of resources, in the context of China’s Adult Higher Education (HE) system. Interviews with 30 students reveal the motivations underpinning their creation of informal ties amongst peers, which they consider to procure beneficial resources for the present and long-term. They deem guanxi with peers to compensate for the isolation they experience. Such experiences, taken in the context of a competitive HE and graduate employment landscape, are then related to social capital. The marriage of the concepts guanxi and social capital is also discussed in light of our analysis.

Carbon nanotube-doped electric hydrogels via ultrafast laser processing and loading conductive polymer

Carbon nanotube, the smallest nanoelectronic materials, has been extensively used as electric materials for chip-scale electronics due to their high electronics conductivity, desirable mechanical properties, and easy surface functionalization. Also the conductive polymer, well-known for its high work function, real-time responsiveness, easy film-formation ability and stretchability. Herein, we combine the carbon nanotube-doped hydrophilic materials with conductive polymer via two-photon hydrogelation for conductivity-tunable functional devices. Taking advantage non-covalent π-π effect, we interpenetrated π-conjugated poly (3,4-ethylenedioxythiophene) into multiwall carbon nanotube-embedded mesoscopic hydrogels, which sustains electronic conductivity, hydrogel-like mechanical properties and desirable tolerance to humid/acid environments. Some reliable, nanostructured, metal-free electronic circuits and interdigital capacitors were fabricated and identified. Carbon nanotube-doped electric hydrogels successfully breaks current limitations by making better use of two photon hydrogelation and intermolecular force with conductive polymer. Moreover, a fast-speed two-photon fluorescence imaging technique using same optical system was deployed to detect the distribution of conductive polymer around electric patterns. Keywords: multi-wall carbon nanotube, conductive polymer, two-photon hydrogelation, mesoscopic electric hydrogels.
Effect of heavy metals on four different earthworm’s species specific autofluorescing eleocytes

Earthworm is key bio-indicator of soil milieu to assess heavy metal contaminations. The celomic fluid of earthworm plays a significant role in the storage of riboflavin within the celomic cavity thereby maintaining its homeostasis. So the measurement of these autofluorescent ‘self-marking’ eleocytes will give more information about chloragocyte derived cells and species. The present study is to investigate the percentage of autofluorescing cells, riboflavin content, elemental and heavy analysis of immunologically significant eleocytes. The present study is focused on four different earthworms namely Lampito mauritii, Octochaetona serrata, Eudrilus eugeniae and Eisenia fetida, to characterize immune factors such as cellular and riboflavin content exposed to various heavy metal concentrations under laboratory conditions. Four different earthworms were exposed to three different concentrations (63.5, 112.4 and 207.2 μg/mL) of heavy metals (Cu, Cd, and Pb) over 96 h. The celomic fluid were subjected for FACS analysis to find out the percentage difference of autofluorescent eleocytes cells between control and exposed species. The discrepancies between riboflavin content of control and heavy metal exposed worms were analyzed by spectrofluorescence. The low and negligible percentage of autofluorescent cells were recorded in E. eugeniae and L. mauritii but large numbers of autofluorescent cells were recorded in E. fetida and O. serrata. The experimental results show that riboflavin content and autofluroscence cells of the heavy metal exposed worms displays significant decrease in the celomic fluid. The present study clearly demonstrated that investigated species possess the significant population of celomocytes, but they differ considerably in the number of cells per body mass and by species. This non-invasive technique proves stable cellular biomarkers in earthworm for toxicological and biological soil monitoring studies.
An Innovative Tour Recommendation System using Graph Algorithms

Background: Tour recommendation and path planning are the most challenging jobs for tourists as they decide Points of Interest (POI). Objective: To reduce the physical effort of the tourists and recommend them a personalized tour is the main objective of this paper. Most of the time people had to find the places he wants to visit in a difficult way. It kills a lot of time.Methods: To cope with this situation we have used different methodology. First, a greedy algorithm is used for filtering the POIs and BFS (Breadth First Search) algorithm will find POI in terms of user interest. The maximum number of visited POI within a limited time will be considered. Then, the Dijkstra algorithm finds the shortest path from the point of departure to the end of tours.Results: This work shows its users list of places according to the user's interest in a particular city. It also suggests them places to visit in a range from the location of the user where a user can dynamically change this range and it also suggests nearby places they may want to visit.Conclusion: This tour recommendation system provides its users with a better trip planning and thus makes their holidays enjoyable.
LA AMBIGÜEDAD LÉXICO-SEMÁNTICA EN EL PROCESO DE ENSEÑANZA-APRENDIZAJE DE LA TRADUCCIÓN: FUNDAMENTOS TEÓRICOS

La ambigüedad léxico-semántica ha sido estudiada por varias disciplinas lingüísticas; mayormente asociada a la comprensión en lengua materna y a la adquisición de segundas lenguas. Sin embargo, este fenómeno lingüístico también afecta la traducción de textos y por ende la habilidad de traducción propiamente, lo cual se refleja desde la formación de traductores. Por tanto, el presente trabajo tiene como objetivo analizar los fundamentos teóricos más importantes del tratamiento de la ambigüedad léxico-semántica en el proceso de enseñanza-aprendizaje de la traducción, a fin de realizar valoraciones que apunten a pautas para su orientación didáctica.
The value of practice simulations and Objective Structured Professional Assessments (OSPAs) for school psychology training: Participant perspectives

ABSTRACT This paper explores trainee educational psychology doctoral students’ experiences of Objective Structured Professional Assessments (OSPAs), implemented at three UK universities and involving participation in a series of timed, simulated scenarios. Focus groups were audio-recorded, transcribed, and subjected to thematic analysis. Themes linked with cognitions included identification of learning processes (reflection, discovery, reception) or practical constraints (authenticity and timing of scenarios). Statements of emotion included positive responses (containment, reassurance, and relief) as well as more adverse reactions to the experience (anxiety and anger). Overall, the findings suggest that many students valued OSPAs as worthwhile and useful in developing professional competencies.

Multi-Domain Modelling of LEDs for Supporting Virtual Prototyping of Luminaires

This paper presents our approaches to chip level multi-domain LED (light emitting diode) modelling, targeting luminaire design in the Industry 4.0 era, to support virtual prototyping of LED luminaires through luminaire level multi-domain simulations. The primary goal of such virtual prototypes is to predict the light output characteristics of LED luminaires under different operating conditions. The key component in such digital twins of a luminaire is an appropriate multi-domain model for packaged LED devices that captures the electrical, thermal, and light output characteristics and their mutual dependence simultaneously and consistently. We developed two such models with this goal in mind that are presented in detail in this paper. The first model is a semi analytical, quasi black-box model that can be implemented on the basis of the built-in diode models of spice-like circuit simulators and a few added controlled sources. Our second presented model is derived from the physics of the operation of today’s power LEDs realized with multiple quantum well heterojunction structures. Both models have been implemented in the form of visual basic macros as well as circuit models suitable for usual spice circuit simulators. The primary test bench for the two circuit models was an LTspice simulation environment. Then, to support the design of different demonstrator luminaires of the Delphi4LED project, a spreadsheet application was developed, which ensured seamless integration of the two models with additional models representing the LED chips’ thermal environment in a luminaire. The usability of our proposed models is demonstrated by real design case studies during which simulated light output characteristics (such as hot lumens) were confirmed by luminaire level physical tests.
Miniaturized photoacoustic probe for in vivo imaging of subcutaneous microvessels within human skin.

Background Subcutaneous microvascular visualization is important for accurate diagnosis and precise treatment of those diseases that are associated with subcutaneous microangiopathy. Pure optical imaging technology and ultrasound imaging technology are commonly used to observe subcutaneous blood vessels non-invasively. However, pure optical imaging is limited to visualizing superficial skin features due to the strong scattering of light by biological tissues, while ultrasound imaging which can detect deep tissues has poor resolution and low contrast to reveal microvascular networks. This results in a lack of intuitive understanding of the disease lesion. Methods A miniaturized photoacoustic (PA) probe, which is capable of imaging subcutaneous microvessels with high resolution and deep penetration, was built in this work. The probe is small enough to be hand-held and takes 16 seconds to obtain a maximum amplitude projection image of 400×400 pixels with the imaging area of 2×2 mm2. Results The miniaturized PA probe was measured to have a lateral resolution of about 8.9 µm and an imaging depth of about 2.4 mm. Besides, in vivo animal experiments and human skin imaging have been implemented. The results show that the miniaturized PA probe not only visualizes the subcutaneous microvessels, but also obtains quantitative information such as the diameters and the depths of blood vessels. Conclusions The miniaturized PA probe has potential been used into clinic, and providing quantitative blood vessel information for the diagnosis and monitoring of vascular diseases.
A hybrid approach for speech enhancement using Bionic wavelet transform and Butterworth filter

Digital noise reduction schemes are proposed for minimizing the output of the hearing aid in the existence of noise. That oversimplification does not observe the reality that individual perception and preference determine which sounds are required and which sounds are not required. Though numerous approaches have been endorsed to diminish the noise level, there is a necessity of development in the noise reduction systems. This paper offered a hybrid method to shrink the commotion in the signals. First, the robust signal is fetched from the database and that signal is subjected to pre-reconstruction with the assistance of empirical mode decomposition. After that the input to Bionic wavelet transform (BWT) is set as the resultant reconstructed signal to derive the de-noised signal. Butterworth filter is used for fine tuning de-noised signal. Consequently, inverse BWT is utilized to derive the final de-noised signal. The recommended methodology is implemented in the MATLAB platform. This method is assessed utilizing more number of noises; furthermore, the technique's performance is matched with the prevailing noise removal techniques.
Silver nanoparticles stabilized with a silicon nanocrystal shell and their antimicrobial activity

The antimicrobial activity of a hybrid nanoparticle (NP) composed of a silver (Ag) NP core decorated with silicon (Si) nanocrystals (NCs) on the exterior (Ag/Si NPs) is evaluated. The shell of Si NCs effectively protects the surface of Ag NPs, thus the particles are more stable in water and in air compared to conventional organic-capped Ag NPs. The bacterial growth kinetic analysis reveals that the Si NC shell does not suppress the release of Ag ions from the Ag NP surface due probably to the porous structure. For the antimicrobial coating application, a thin film of the hybrid Ag/Si NPs is produced by drop coating the solution on a cover glass. Thanks to the Si NC shell, agglomeration of Ag NPs in the film is prevented and the film shows a very similar optical absorption spectrum to that of the solution. The film exhibits a larger zone of inhibition in an agar diffusion assay of Escherichia coli compared to a film produced from organic-capped Ag NPs.
Corporate social responsibility: An old wine in a new gourd

A corporation’s moral obligation is said to be sustained by two viewpoints: the narrow and broad views. The narrow view restrains a corporation’s moral obligation to the corporation’s owners and shareholders while the broad view, which is often deployed to support Corporate Social Responsibility initiatives, extends the corporation’s moral obligation towards others beyond the confines of the corporation walls to include all stakeholders, and the environment in which the corporation operates and so on. We argue from an ethical perspective that this dichotomy is a facade. We conclude that the broad view is indeed a narrow view in disguise. Key words: Corporate Social Responsibility (CSR), broad view, narrow view, stakeholders, stockholders, egoism.
Carbon Dioxide Adsorption on Porous and Functionalized Activated Carbon Fibers

Polyacrylonitrile-based activated carbon fibers (ACFs), modified using potassium hydroxide (KOH) or tetraethylenepentamine (TEPA), were investigated for carbon dioxide (CO2) adsorption, which is one of the promising alleviation approaches for global warming. The CO2 adsorption isotherms were measured, and the values of isosteric heat of adsorption were calculated. The results showed that the KOH-modified ACFs exhibited a great deal of pore volume, and a specific surface area of 1565 m2/g was obtained. KOH activation made nitrogen atoms easily able to escape from the surface of ACFs. On the other hand, the surface area and pore volume of ACFs modified with TEPA were significantly reduced, which can be attributed to the closing or blocking of micropores by the N-groups. The CO2 adsorption on the ACF samples was via exothermic reactions and was a type of physical adsorption, where the CO2 adsorption occurred on heterogeneous surfaces. The CO2 uptakes at 1 atm and 25 °C on KOH-activated ACFs reached 2.74 mmole/g. This study observed that microporosity and surface oxygen functionalities were highly associated with the CO2 uptake, implying the existence of O-C coordination, accompanied with physical adsorption. Well cyclability of the adsorbents for CO2 adsorption was observed, with a performance decay of less than 5% over up to ten adsorption-desorption cycles.
The lottery of spermatogenesis

The causes of male infertility are yet to be fully understood. Here, we propose that male infertility can be partly attributed to the insufficiency of cytoplasmically-inherited proteins in sperms. Using a simple stochastic model of spermatogenesis, we show that in a range of parameters, the proportion of viable sperms can be reduced simply due to stochastic transmission of proteins from spermatogonia to spermatids.
Fault Slip Through measurement in software development process

The pressure to improve software development process is not new, but in today's competitive environment there is even greater emphasis on delivering a better service at lower cost. In market-driven development where time-to-market is of crucial importance, software development companies seek improvements that can decrease the lead-time and improve the delivery precision. One way to achieve this is by analyzing the test process since rework commonly accounts for more than half of the development time. A large reason for high rework costs is fault slippage from earlier phases where they are cheaper to find and remove. As an input to improvements, this article introduces a measure that can quantify this relationship. That is, a measure called faults-slip-through, which determines the faults that would have been more cost-effective to find in an earlier phase.
Blood Pressure and Echocardiographic Changes in College Football Players

Football players are widely recognized for their physical prowess. Decades of research have demonstrated that physical activity and fitness are associated with lower all-cause mortality and a variety of health benefits in healthy individuals and individuals with chronic diseases. The specific mechanisms responsible for these outcomes appear to be multifactorial and include a reduction in cardiovascular risk factors, and favorable effects on thrombosis, inflammation, endothelial function, and autonomic tone. However, a distinction must be made between competitive sports and recreational exercise, the latter from which the majority of research on the benefits of exercise are derived. The physiological and emotional demands during training and performance of competitive athletics are indeed quite different. Competitive athletes participate in an organized sport that rewards athletic excellence and achievement and requires systematic training and regular competition. Accordingly, these athletes characteristically extend themselves to high levels of effort for long periods of time, often doing so regardless of other considerations. Although the health benefits of regular exercise and physical activity are unequivocal, and overall cardiovascular risks during exercise and sports activities appear to be low, a small proportion of athletes often with undiagnosed pathological cardiac conditions are at risk of tragic cardiovascular events. Most known hazards described in football players are traumatic, and these include musculoskeletal injury and the newly described, very disturbing potential risk of chronic traumatic encephalopathy. Yet, sudden cardiac death is the leading medical cause of death and cause of death during exercise in National Collegiate Athletic Association student–athletes. A recent series demonstrates this risk to be 1:38 497 football players per year. Are there other, more insidious cardiovascular health risks to college football players perhaps incurred by the lifestyle, diet, and training demands of these players? This question is addressed by the provocative study by Weiner et al in this issue of Circulation.
Antimicrobial Polyurethane Containing an Association of Antibiotics

Introduction The use of polymeric devices for temporary implantation has progressed greatly in latter years. However, implant infection is a serious complication (1), mainly due to Staphylococcus aureus, coagulase negative Staphylococcus epidermidis. Antimicrobial agents adsorbed on implant surfaces are possible approaches to prevent infections. For this purpose, we realized surfaces that minimized the risk of deviceassociated infections, through antibiotic adsorption on suitably modified biocompatible polymeric materials. To improve the resistance of the device to microbial infections, a combination of two antibiotics, cefamandole nafate (CEF) and a rifampin (RIF), having different action mechanisms, were adsorbed on functionalized polyurethane films. The polymers were characterized by FTIR and H-NMR spectroscopy, water swelling, dynamic contact angle measurement and thermal analysis. Antibiotic release kinetics were evaluated by in vitro tests. Antibiotic release increased by adding, as pore formers, polyethylenglycol (PEG) of a different molecular weight.
