Hierarchical nanostructured electrospun carbon fiber/NiCo2O4 composites as binder‐free anodes for lithium‐ion batteries

Hierarchical structured composite materials consisting of NiCo2O4 and electrospun carbon fibers were fabricated through the coprecipitation of NiCo compounds on electrospun carbon fibers. Post thermal treatment converted NiCo compounds to NiCo2O4. We aimed to identify how different fiber diameters affect the structures and electrochemical performance of NiCo2O4/carbon fiber composites. Carbon fibers with diameters smaller than 400 nm resulted in the formation of NiCo2O4 needles, whereas those with diameters larger than 800 nm resulted in the development of NiCo2O4 flowers. The composites with needle‐type NiCo2O4 exhibited richer mesopores and larger specific surface areas than fibers with flower‐like NiCo2O4 did. When used as lithium‐ion battery anodes, the needle‐like and flower‐like composites exhibited specific capacities of 639 and 498 mAh/g, respectively, at a current density of 200 mA/g after 100 cycles, which were much higher than pristine carbon fibers. The enhanced specific capacity resulted from the combinative effects of the efficient electron transfer in the carbon fiber networks and the high specific capacity of NiCo2O4. Furthermore, needle‐like materials with large mesopore volume allowed for the accommodation of volume changes and favored fast lithium‐ion transfer during continuous electrochemical reactions, leading to more favorable cycling stability and rate capability than the flower‐like materials did.
Cerebrocortical proteome profile of female rats subjected to the western diet and chronic social stress

ABSTRACT The energy-dense western diet significantly increases the risk of obesity, type 2 diabetes, cardiovascular episodes, stroke, and cancer. Recently more attention has been paid to the contribution of an unhealthy lifestyle on the development of central nervous system disorders. Exposure to long-lasting stress is one of the key lifestyle modifications associated with the increased prevalence of obesity and metabolic diseases. The main goal of the present study was to verify the hypothesis that exposure to chronic stress modifies alterations in the brain proteome induced by the western diet. Female adult rats were fed with the prepared chow reproducing the human western diet and/or subjected to chronic stress induced by social instability for 6 weeks. A control group of lean rats were fed with a standard diet. Being fed with the western diet resulted in an obese phenotype and induced changes in the serum metabolic parameters. The combination of the western diet and chronic stress exposure induced more profound changes in the rat cerebrocortical proteome profile than each of these factors individually. The down-regulation of proteins involved in neurotransmitter secretion (Rph3a, Snap25, Syn1) as well as in learning and memory processes (Map1a, Snap25, Tnr) were identified, while increased expression was detected for 14-3-3 protein gamma (Ywhag) engaged in the modulation of the insulin-signaling cascade in the brain. An analysis of the rat brain proteome reveals important changes that indicate that a combination of the western diet and stress exposure may lead to impairments of neuronal function and signaling.
Environmental disclosure quality and risk: the moderating effect of corporate governance

Purpose The purpose of this article is to investigate the relationship between environmental disclosure quality (EDQ) and risk and to further examine whether corporate governance (CG) practices moderate this relationship. Design/methodology/approach This study uses a set of unique, hand collected data (from 2011 to 2016) to measure EDQ for a sample of 762 firm-years Iranian listed companies. Ordinary least squares regression analysis is performed in testing hypotheses after controlling for a variety of firm, industry and year effects. Moreover, several analyses are performed to establish the robustness of the findings. Findings The results indicate a negative association between EDQ and firm risk. While board independence moderates this relationship, other CG practices such as CEO duality and board size do not show any effects on the relationship between EDQ and risk. The results remain robust after performing sensitivity tests and under various specifications, including the fixed-effects panel data and Heckman two-stage regressions. Research limitations/implications Results are from a sample of firms from one country. Practical implications The results have implications for policymakers, legislators and corporate executives, as environmental initiatives are gaining more attention worldwide. Social implications Sustainability initiatives in the areas of environmental and social performance and disclosure are gaining global attention. This study addresses the link between firm risk and EDQ. Originality/value This study contributes to the literature by shedding light on the relationship between corporate risk-taking and EDQ in the context of a developing economy.
Links between Maternal Employment and Child Nutrition in Rural Tanzania

Improving child nutrition and empowering women are two important and closely connected development goals. Fostering female employment is often seen as an avenue to serve both these goals, especially if it helps to empower the mothers of undernourished children. However, maternal employment can influence child nutrition through different mechanisms, and the net effect may not necessarily be positive. We develop a theoretical model to show that maternal employment can affect child nutrition through changes in income, intrahousehold bargaining power, and time available for childcare. The links are analyzed empirically using panel data from farm households in rural Tanzania. We find that the links between maternal employment and child height-for-age Z-scores (HAZ) are non-linear. Off-farm employment is negatively associated with child HAZ at low levels of labor supply. The association turns positive at higher levels of labor supply and negative again at very high levels. The associations between maternal on-farm work and child nutrition are weaker and not statistically significant. These findings can help to better design development interventions that foster synergies and avoid potential tradeoffs between female empowerment and child nutrition goals.
Disease cycle of Austropuccinia psidii on Eucalyptus globulus and Eucalyptus obliqua leaves of different rust response phenotypes

Myrtle rust poses a signiﬁcant biosecuri ty threat to Australia with potential for long-term damaging impacts on nativeﬂora and plant industries. This study describes the disease cycle of Austropuccinia psidii, the myrtle rust pathogen, in Eucalyptus globulus and Eucalyptus obliqua, two commercially and ecologically important species from different sub-genera of Eucalyptus. Ontogeny and morphology of infection structures of A. psidii on plants of both Eucalyptus species with different rust response phenotypes, i.e. completely resistant, hypersensitive and highly susceptible, were investigated. Plants were inoculated with single-uredinium-derived urediniospores and examined by scanning electron microscopy. No differences between rust response phenotypes were observed in germination of urediniospores, formation of appressoria or length of germ tubes. The growth of germ tubes had no afﬁnity towards stomata of either spe cies. Histological observations indicated direct penetration by infection pegs through the leaf cuticle and no penetration beyond the epidermis on rust-resistant E. obliqua.Eucalyptus obliqua plants that were identiﬁed as susceptible to A. psidii at 3- and 6-months-old showed no disease when reinoculated with A. psidii at 12-months-old; this indicated possible early acquisition of adult plant resistance to A. psidii in this species. In the susceptible phenotype of E. globules rust inoculation led to rapid colonization of leaf parenchyma cells with the disease cycle completed within 10 days. These ﬁndings provide valuable insights into host – pathogen interactions in the Eucalyptus – A. psidii pathosystem,which might be useful for the development of effective rust control strategies across Eucalyptus subgenera.
Detección y cuantificación de virus de hepatitis A en moluscos en las bahías de Concepción y Arauco, Chile.

Antecedentes: El virus de la Hepatitis A (VHA) se asocia comunmente al consumo y manipulacion de alimentos contaminados, entre otras causas, destacandose los moluscos bivalvos como una de las categorias de alimentos frecuentemente relacionadas a grandes brotes. La prevalencia y epidemiologia de la enfermedad varia entre y al interior de cada pais. En Chile, la region del Biobio es actualmente de alta endemia de VHA, especialmente en comunas del borde costero, asociandose a insuficiencias en el saneamiento ambiental. Objetivo: Detectar y cuantificar las particulas virales de VHA en moluscos en las bahias de Concepcion y Arauco, region del Biobio, Chile, para el ano 2016. Como una forma de evaluar la capacidad bioacumuladora de los moluscos bivalvos consumidos localmente y por ende el riesgo de enfermedad Metodologia: Se analizaron 72 muestras, de la zona, correspondientes cada una, a un pool de hepatopancreas proveniente de 10 especimenes. La deteccion se realizo via retro PCR en tiempo real (RT-qPCR), y la cuantificacion mediante la utilizacion de curva estandar realizadas para cada virus, interpolando los resultados de Cq observados, solo en el caso de las muestra VHA positivas. Resultados: El virus fue detectado en 35 de 72 muestras de moluscos principalmente almejas y mejillones de las dos bahias. La concentracion de moluscos encontradas fue entre 10 y 3.900 copias del genoma por gramo de hepatopancreas. Discusion: Desde al ano 2000 al 2013, la region presentaba tasas de baja endemia similares al resto del pais, periodo en que el pais logro mejorar significativamente sus condiciones sanitarias. Los resultados sugieren la necesidad de reevaluar y fortalecer el saneamiento ambiental. Es necesario promover politicas que resguarden la produccion formal de alimentos libres de patogenos, pero que tambien consideren la extraccion informal. Asi como es necesario generar sistemas de vigilancia de VHA conjuntos, clinicos, epidemiologicos y ambientales.
Can indicators for sustainable tourism improve tourism planning in the coastal
destinations?

Due to the continuous increase of the tourism industry, tourism destinations need to be managed under a sustainable framework, with the main aim of minimizing the adverse effects caused by tourism flows. In recent years, several attempts have been made to measure those effects and value the level of sustainability of every destination. A clear example of this is the European Tourism Indicator System (ETIS). In the paper, the results are presented of a project which aimed to test indicators of sustainable tourism in coastal destinations of Catalonia, Istrian Region, and Tuscany Region. The results of 33 collected indicators are available on the online platform of the project INTERREG MED MITOMED+. During the first year, in every category of indicators (economic, social-cultural and environmental) only some indicators were collected, which was expected because different regions apply different methodologies. The collected data is the starting point that shows destinations how the indicator can be obtained and what its purpose is. Furthermore, collected data can help local and regional tourism stakeholders to prevent factors of risk, to take decisions and to improve the implementation of policies for sustainable maritime and coastal tourism development in the Mediterranean area.
Playing in the backstore: interface gamification increases warehousing workforce engagement

PurposeIn a warehouse setting, where hourly workers performing manual tasks account for more than half of total warehouse expenditure, a lack of employee engagement has been directly linked to company performance. In this article, the authors present a laboratory experiment in which two gamification elements, goal setting and feedback, are implemented in a wearable warehouse management system (WMS) interface to examine their effect on user engagement and performance in an item picking task. Both implicit (neurophysiological) and explicit (self-reported) measures of engagement are used, allowing for a richer understanding of the user's perceived and physiological state.Design/methodology/approachThis experiment uses a within-subject design. Two experimental factors, goals and feedback, are manipulated, leading to three conditions: no gamification condition, self-set goals and feedback and assigned goals and feedback. Twenty-one subjects participated (mean age = 24.2, SD = 2.2). FindingsThis article demonstrates that gamification can successfully increase employee engagement, at least in the short-term. The integration of self-set goals and feedback game elements has the greatest potential to generate long-term intrinsic motivation and meaningful engagement, leading to greater employee engagement and performance.Originality/valueThis article explores the underlying effects of gamification through two of the most prominent motivational theories (self-determination theory [SDT] and goal-setting theory) and one of the leading employee engagement models (job demands-resource model [JD-R[ model). This provides a theory-rich interpretation of the data, which allows to uncover the motivational pathways by which gamification affects engagement and performance.
Effects of assembling method and force on the performance of proton‐exchange membrane fuel cells with metal foam flow field

Recently, highly porous metal foams have been used to replace the traditional open‐flow channels to improve gas transport and distribution in the cells. Deformation of flow plate, gas diffusion layer (GDL), and metal foam may occur during assembling. When the cell size is small, the deformation may not be significant. For large area cells, the deformation may become significant to affect the cell performance. In this study, an assembling device that is capable of applying uniform clamping force is built to facilitate fuel cell assembling and alleviate the deformation. A compressing plate that is the same size of the active area is used to apply uniform clamping force before surrounding bolts are fastened. Therefore, bending of the flow plate and deformation of GDL and metal foam can be minimized. Effects of the clamping force on the microstructures of GDL and metal foam, various resistances, pressure drops, and cell performance are investigated. Distribution of the contact pressure between metal foam and GDL is measured by using pressure sensitive films. Field‐emission scanning electron microscope is used to observe the microstructures. Electrochemical impedance spectroscopy analysis is used measure resistances. The fuel cell performance is measured by using a fuel cell test system. For the cell design used in this study, the optimum clamping force is found to be 200 kgf. Using this optimum clamping force, the cell performance can be enhanced by 50%, as compared with that of the cell assembled without using clamping plates. With appropriate clamping force, the compression force distribution across the entire cell area can approach uniform. This enables uniform flow distribution and reduces mass transfer resistance. Good contact between GDL and metal foam also lowers the interface resistance. All these factors contribute to the enhanced cell performance.
Exploiter des modèles de langue pour évaluer des sorties de logiciels d'OCR pour des documents français du XVIIe siècle ()

Pour comparer deux sorties de logiciels d’OCR, le Character Error Rate (ou, CER) est frequemment utilise. Moyennant l’existence d’une verite de terrain de qualite pour certains documents du corpus, le CER calcule le taux d’erreur de ces pieces et permet ensuite de selectionner le logiciel d’OCR le plus adapte. Toutefois, ces verites de terrain sont tres couteuses a produire et peuvent freiner certaines etudes, meme prospectives. Nous explorons l’exploitation des modeles de langue en agregeant selon differentes methodes les probabilites offertes par ceux-ci pour estimer la qualite d’une sortie d’OCR. L’indice de correlation de Pearson est ici utilise pour comprendre dans quelle mesure ces estimations issues de modeles de langue covarient avec le CER, mesure de reference.
Secular Trends in the Achievement of Physical Activity Guidelines: Indicator of Sustainability of Healthy Lifestyle in Czech Adolescents

(1) Background: The increasing socio-economic and educational demands on adolescents should be reflected in their lifestyles accordingly. The aim of the study was therefore to identify the trends in the achievement of physical activity (PA) guidelines by Czech adolescents through objective and subjective PA monitoring. (2) Methods: The research was carried out between 2010 and 2017 and involved 49 secondary schools, 2 higher vocational schools, and 8 universities in the Czech Republic. In total, the projects involved 1129 girls and 779 boys. PA monitoring was performed by Yamax SW-700 pedometers and IPAQ-long questionnaires. (3) Results: The results according to the average number of steps/day confirm a decrease in the amount of PA in boys and girls and in the achievement of the recommended 11,000 steps/day. However, the estimates of meeting the recommended weekly PA expressed as MET-min/week based on the IPAQ-long questionnaire are not so convincing about the decrease. (4) Conclusions: The combination of objective monitoring of weekly PA using wearables and subjective estimates of weekly PA using a questionnaire regarding the ease of application, appears to be a sufficient indicator of the status of and trend in PA and thus the sustainability of a healthy lifestyle in youths.
Asymmetry in Charge Transfer Pathways Caused by Pigment–Protein Interactions in the Photosystem II Reaction Center Complex

This article discusses the photoinduced charge transfer (CT) kinetics within the reaction center complex of photosystem II (PSII RC). The PSII RC exhibits a structural symmetry in its arrangement of pigments forming two prominent branches, D1 and D2. Despite this symmetry, the CT has been observed to occur exclusively in the D1 branch. The mechanism to realize such functional asymmetry is yet to be understood. To approach this matter, we applied the theoretical tight-binding model of pigment excitations and simulated CT dynamics based upon the framework of an open quantum system. This simulation used a recently developed method of computation based on the quasi-adiabatic propagator path integral. A quantum CT state is found to be dynamically active when its site energy is resonant with the exciton energies of the PSII RC, regardless of the excitonic landscape we utilized. Through our investigation, it was found that the relative displacement between the local molecular energy levels of pigments can play a crucial role in realizing this resonance and therefore greatly affects the CT asymmetry in the PSII RC. Using this mechanism phenomenologically, we demonstrate that a near 100-to-1 ratio of reduction between the pheophytins in the D1 and D2 branches can be realized at both 77 K and 300 K. Our results indicate that the chlorophyll Chl D 1 is the most active precursor of the primary charge separation in the D1 branch and that the reduction of the pheophytins can occur within pico-seconds. Additionally, a broad resonance of the active CT state implies that a large static disorder observed in the CT state originates in the fluctuations of the relative displacements between the local molecular energy levels of the pigments in the PSII RC.
Catcher in the Mind: An Examination of Visual and Verbal Patterns during Reading

This study examined the nature of individuals’ thoughts during reading. We examined whether self-reports of thought characteristics (i.e., mind wandering, visual, verbal, valence) varied across time and task. In two sessions, participants (n=85) responded to thought probes across focused meditation and narrative reading tasks. Results showed that participants’ thought patterns were stable across sessions. Further, reports of mind wandering, visual imagery, and valence varied based on task, whereas verbal thinking remained stable across tasks. this study presents some of first work to systematically examine the role of visual and verbal thought during reading. Additional analyses will examine how individuals’ reports of visual imagery relate to their recall of text information, as well as the impact of individual differences known to be important to comprehension. Future studies will examine how participants’ reports of visual imagery relate to comprehension processes, such as the generation of inferences or the access to prior knowledge. These studies have the potential to provide more clarity on the comprehension process as it relates to individuals’ own conscious experiences.

WhatsApp Chat Visualizer: A Visualization of WhatsApp Messenger’s Artifact Using the Timeline Method

WhatsApp is a medium that everyone can use to interact and to share information effectively and efficiently. However, it can be misused for criminal activities. Analyzing WhatsApp' artifacts is quite challenging as the suspect may have a lot of random conversational data to be considered. This makes it difficult for the trial process to obtain digital traces that can be identified in malicious activities such as knowing who was involved when the conversation was held and the timespan. Therefore, in this research, a social media investigation of WhatsApp was carried out by acquiring data from rooted Android devices that were used as target devices for forensic activities. A python-based application is developed to show the content of the conversation, and a web-based application is presented to visualize the data using the Timeline method. Experimental results in this research display important timeline information such as information about who was involved when and what time the conversation was carried out with the suspect.
