The sociocultural shaping of mothers’ doing, being, becoming and belonging after returning to work

ABSTRACT The aim of this study was to explore the influence of social ideologies on the doing, being, becoming, and belonging of Western employed professional women who are new mothers, after returning to work outside the home within the first 18 months after giving birth. Although occupational science has provided valuable insights into mothering occupations, it perpetuates an individualistic focus that often neglects the complex and multifaceted societal influence on mothering. A narrative approach was used to collect and analyse data from seven Swiss women who had returned to professional level jobs after giving birth to their first child. Hitch et al.’s (2014a, 2014b) framework was employed to analyse how social ideologies influence working mothers’ doing, being, becoming, and belonging. The findings are presented through stories that illustrate the complex interplay between social norms and participants’ possibilities for doing and being as mothers and workers. Three stories are presented: ‘Balancing being a mother and work: The aspect of doing’; I don’t want to be seen as the mother only: The aspect of being a mother and belonging at work’; and ‘As a mother, you get criticised a lot: The aspect of doing and belonging to society’. This study enriches current understandings of how social ideologies pervade the context in which occupations are performed and how working mothers are influenced by them in their doing, being, becoming, and belonging.
Exploring the connection between odour and clothing disposal

Abstract Increasing textile waste poses a significant environmental problem. There are many motivating factors that can influence a person's choice about when and how to dispose of unwanted clothing. The development and persistence of odour within clothing may be one such factor. The purpose of this study was to explore the relationship between clothing odour and disposal behaviour. In particular, whether consumers dispose of odorous clothing differently from non-odorous clothing. A questionnaire was developed and distributed to a convenience sample through social networks. Responses from 529 consumers residing in Canada and the United States were analysed. The majority of respondents (98.7%) have perceived odour in a clothing item at some point. Of these, approximately half had gotten rid of an article of clothing at some time because it became too odorous to wear. Odour was not a major reason for consumers to discard their clothing. However, when odour was a reason for disposal, respondents reported they were less likely to donate, give-away or sell odorous clothing and more likely to throw odorous clothing items directly into the trash. Therefore, although persistent odour in clothing plays only a minor role on sustainable disposal behaviour, when odour is a motivating factor for discard it leads to less sustainable disposal practices.
Effect of Vegetation Removal on Soil Erosion and Bank Stability in Agricultural Drainage Ditches

Maintenance of agricultural drainage ditches can be difficult to optimize if farmers have no guidelines on where to target their maintenance efforts. A main concern is whether ditch banks will experience soil erosion or mass movement (failure). In order to help identify sites that are more likely to experience soil erosion and/or mass movement, soil susceptibility to detachment was assessed in this study using a cohesive strength meter (CSM) and measurements of shear strength in unsaturated direct shear tests. The results showed that soil roots play an important role in stabilizing ditch banks against mass movement and in reducing the rate of soil detachment. A positive stabilizing effect was detected by CSM and confirmed by shear strength measurements. The conclusion is that native vegetation should be maintained on ditch banks, instead of being removed during maintenance work as is currently the case.
Investigation on energy harvesting enabled device-to-device networks in presence of co-channel interference

Energy harvesting from ambient radio-frequency (RF) sources has been a novel approach for extending the lifetime of wireless networks. In this paper, a cooperative device-to-device (D2D) system with the aid of energy-constrained relay is considered. The relays are assumed to be able to harvest energy from information signal and co-channel interference (CCI) signals broadcasted by nearby traditional cellular users and forward the source’s signal to its desired destination (D2D user) utilizing amplify-andforward (AF) relaying protocol. Time switching protocol (TSR) and power splitting protocol (PSR) are proposed to assist energy harvesting and information processing at the relay. The proposed approaches are applied in a model with three nodes including the source (D2D user), the relay and the destination (D2D user), the system throughput is investigated in terms of the ergodic capacity and the outage capacity, where the analytical results are obtained approximately. Our numerical results verify the our derivations, and also points out the impact of CCI on system performance. Finally, this investigation provide fundamental design guidelines for selecting hardware of energy harvesting circuits that satisfies the requirements of a practical cooperative D2D system.
Single step lithography for double-recessed gate pseudomorphic high electron mobility transistors

An asymmetric double-recessed gate process achieved through a single lithography step and a combination of wet and dry etching techniques is presented. The double-recessed gate process is beneficial in the fabrication of InGaAs/AlGaAs/GaAs pseudomorphic high electron mobility transistors (PHEMTs) because breakdown voltage is enhanced while surface effects on the drain side of the gate are minimized. In contrast to conventional processes that require two lithography steps, the current process requires only a single lithography step for the asymmetric placement of a T-gate in a wide recess trench. The process utilizes a four-layer resist of polymethylmethacrylate (PMMA) and P(MMA-MAA) exposed by electron beam lithography. Upon development of the resist, a wet selective etch (citric acid:H2O2) is used to define the wide recess trench and then a dry selective etch (SiCl4/SiF4) is used to recess a narrow trench (within the wide recess trench) in which the gate foot rests. This technique can achieve gate length.
Video Seals Recognition using Transfer Learning of Convolutional Neural Network

This paper deals with the binary classification of seals videos. To address this problem, we propose a novel system based on two phases : offline and online. The offline phase aims to generate a trained model. For this end, we use a transfer learning of convolutional neural network approach. Especially, we employed the VGG-16 deep network trained on the large ImageNet database and transfer their hyperparameters to recognize seals in the video. Finally, fully connected layer followed by a softmax method are used to decide if the seals exist or not in a given frame. For the online phase, we extract different information from a given video based on the file video name and on the trained model in the offline phase. The evaluation of the proposed method in a seals videos database demonstrates promising results.
Religiosity from Age 12 to 20: Stability, Change, and Bidirectional Effects of Attendance, Prayer, and Salience

ABSTRACT Religiosity is a protective factor for adolescents, though research has indicated religiosity declines across adolescence. However, little research has examined how various dimensions of religiosity may change across time. With yearly data from a sample of 489 participants, the current study examined rank-order and mean level changes in religiosity from early adolescence (12 years-old) into late adolescence/emerging adulthood (20 years-old). Three dimensions of religiosity were examined, public religious practices (religious service attendance), private religious practices (prayer), and religious salience. Using cross-lagged models, reciprocal relationships between these dimensions were examined. There was significant rank-order stability, though stability was highest for attendance. The mean of all three dimensions decreased over time. The decline for attendance was initially slow though the decline increased through late adolescence. Prayer declined linearly and religious salience declined rapidly during early adolescence with the decline dampening in later adolescence and late adolescence. Each dimension was reciprocally related to the other dimensions, though this relationship differed across time. For instance, in early adolescence, attendance predicted religious salience and in late adolescence, salience predicted attendance. When significant, parent income and education were negatively associated with religiosity.
Talking War: Representation, Veterans and Ideology in Post-War Parliamentary Debates

Abstract How do politicians in post-war societies talk about the past war? How do they discursively represent vulnerable social groups created by the conflict? Does the nature of this representation depend on the politicians’ ideology or their record of combat service? We answer these questions by pairing natural language processing tools and a large corpus of parliamentary debates with an extensive data set of biographical information including detailed records of war service for all members of parliament during two recent terms in Croatia. We demonstrate not only that veteran politicians talk about war differently from their non-veteran counterparts, but also that the sentiment of war-related political discourse is highly dependent on the speaker's exposure to combat and ideological orientation. These results improve our understanding of the representational role played by combat veterans, as well as of the link between descriptive and substantive representation of vulnerable groups in post-war societies.
Full fluid moment model for low temperature magnetized plasmas

A one-dimensional full fluid moment model is developed to study shear-induced electron transport in low-temperature, partially magnetized plasmas. Ions and electrons are treated as two different fluids that interact with each other through collisions and electromagnetic fields. Conservation of mass, momentum, and energy is solved for both the fluids and the Poisson equation is solved to obtain the electrostatic electric field. A global Lax–Friedrichs flux splitting scheme with a monotonic upwind scheme for conservation laws is used for the inviscid flux calculation. Moments of a shifted Maxwellian distribution that is constructed from the fluid quantities are taken to calculate fluxes at the boundaries, henceforth called the kinetic fluxes. Two full fluid moment models are developed based on the treatment of the electron energy: (i) the total energy and (ii) the internal energy, i.e., temperature. A DC low-temperature magnetized plasma in a Hall effect thruster is modeled using the full fluid moment model and the results are compared with drift-diffusion models that are commonly used for low-temperature plasmas, providing insights into nonclassical electron transport driven by the electron shear in cross-field devices.
Determination of Analgesics (Dipyrone and Acetaminophen) in Pharmaceutical Preparations by Cyclic Voltammetry at a Copper(II) Hexacyanoferrate(III) Modified Carbon Paste Electrode

Copper(II) hexacyanoferrate(III) (CuHCF) modified carbon paste electrode was used for the electroanalytical determination of dipyrone and acetaminophen in pharmaceutical preparations by cyclic voltammetry. Several parameters were investigated for the optimization of the sensor such as composition of the electrode, electrolytic solution, effect of pH, scan rate of potential and interference. The best conditions were found for an electrode composition in mass of 20% CuHCF, 55% graphite and 25% mineral oil in acetate buffer containing 0.05 mol L -1 of NaCl. The analytical curve was linear in the dipyrone and acetaminophen concentration ranged from 1.25 x 10 -5 mol L -1 to 1.23 x 10 -3 and 2.84 x 10 -4 to 2.59 x 10 -3 mol L -1 respectively, being successfully applied to the determination of dipyrone and acetaminophen in phar- maceutical preparations. The CuHCF modified carbon paste electrode presented comparable results to those obtained us- ing iodimetry and ultraviolet spectrophotometry methods, respectively.
Wealth creation through corporate diversification – the bondholders’ perspective

The influence of corporate diversification on firm value is an important field in strategy research. Studies in strategic management and finance research have analyzed value creation through product and geographic diversification from a shareholder’s perspective. This study completes this picture by analyzing the bondholders’ perspective. It is suggested that product diversification creates value for bondholders, while geographic diversification destroys bondholder value. The hypotheses are tested on a sample of S&amp;P 1,200 firms in 2001–2011 using a fixed-effects panel model. Drawing on prior research, bondholder value creation is measured using the Merton model. The empirical results support the hypothesis that bondholders gain value through product diversification but lose value through geographic diversification. Considering prior research results, these results show that product diversification is preferable for bondholders, while geographic diversification is preferable from a shareholder’s perspective. The opposite effects of both diversification strategies on shareholders, respectively, bondholders offer an important new perspective on corporate diversification. The results show that firms with a high level of corporate debt should struggle to justify a strategy involving geographic dispersion of activities and support a more diversified product portfolio strategy. This study also offers several avenues for investigating the bondholder’s perspective on corporate diversification in more detail.
Assessment of anti-cancer potential of Hyalomma dromedarii salivary glands extract: in vitro study

Cancer is still one of the deadly diseases worldwide and the need for naturally-derived effectors is a pursued aim in health research. With the outstanding ability to bypass the host’s various defense mechanisms, tick saliva constitutes an interesting rich source for the discovery of therapeutically-valuable molecules. Therefore, the present work aimed to evaluate the anti-tumor potential of Hyalomma dromedarii salivary glands extract (SGE). Three cell lines were used in this study, namely HCT116 (colorectal cancer), A549 (lung cancer) and HFB4 (normal skin) cells. MTT assay and light microscopy revealed significant dose-dependent inhibition of proliferation with obvious morphological changes in tested cell lines. Colon cells exhibited more sensitivity than lung ones, therefore they were selected for further investigations. Although cytotoxic effects were observed in treated-HFB4 cells, its IC50 value was much higher than that of HCT116 cells. Flow cytometry analysis of treated HCT116 cells showed accumulation of cellular DNA at the G2/M phase and induction of apoptosis. In addition, RT-qPCR indicated down-regulation in the expression of vascular endothelial growth factor (VEGF), fibroblast growth factor-2 (FGF-2), transforming growth factor-β (TGF-β) and interleukin-4 (IL-4) genes. These results demonstrated that H. dromedarii SGE has anti-proliferative, apoptotic and anti-angiogenic potential. Also, they open perspectives for characterization of effective molecules that could be used in developing treatments for colorectal cancer. Further investigations are required to identify the mechanisms, molecules and signaling pathways involved in the inhibitory effect of the SGE.
Sustainable Smart Cities and Energy Management: The Labor Market Perspective

Nowadays, sustainability is one of the strategic goals of smart cities. They are the essential solution to creating the sustainable future. On the other hand, the smart city is intended to deal with the problems of energy management. This paper examines the influence of the smart sustainable cities concept on energy management from the labor market perspective. The paper fulfills the research gap about energy manager profession transformation considering smart sustainable city concept. The aim of the paper is to create an up-to-date holistic energy manager skill model with a focus on emerging technologies. The skill model reflects the synergy of two methodological approaches: the theoretical and practical approaches. Descriptive statistics are used to present the labor market research results. It is concluded that the core elements of the smart sustainable city concept have an impact on energy management are sustainability and big data. The labor market research also draws differences in the amount and structure of demand on energy manager skills by countries, but at the same time similar skills requirements are found. The skill model of the energy manager profession is built around several main groups associated with specific knowledge, social skills, and behavior skills. The findings of the present research can contribute to knowledge and practice by applying it in the process of developing energy manager competency models in commercial and non-commercial enterprises as well as in education programs and training courses.
Financial and Biotechnological Assessment of New Oil Extraction Technology

Grape seed oil is recognized for its high quality bioactive compounds, however, these are sensitive to increased temperatures during manufacture. Technical and economical potential of the pretreatment in combination with the mixture of hydrolyzing enzymes have been analyzed. It was confirmed that the shockwave pretreatment significantly enhances the subsequent enzymatic hydrolysis, which subsequently better liberates the vacuoles rich in oil (without exceeding the temperature limitation). The assessment of oil yields achieved together with the holistic cost analysis indicates that this technology has significant technical potential. Admittedly, it still faces difficulties linked with increased cost of production.
Development of a Robotic Hand Orthosis for Stroke Patient Rehabilitation

This study developed a robotic orthosis capable of detecting the intention of a wearer to move their fingers, thereafter augmenting their muscle force. This was with the aim of producing a device that can be used in post-stroke hand rehabilitation. The design of the orthosis was based on an existing design, which was modified using BLENDER release 2.78 and printed with ABS plastic. An actuator was mounted at the rear end of the orthosis, to provide actuation to perform full range flexion and extension motion for digits. Force sensors were embedded at the fingertips of the orthosis to detect minute finger movements. For severe cases where stroke survivors are incapable of little finger movements, the study employed a brain-computer interface to detect the intent to move. The robotic orthosis achieved an accuracy of 64.1% and 62% in detecting unclench and clench activities respectively and actuating the orthosis digits in response. The results revealed that the design presented here can help provide effective hand rehabilitation. The study concluded that the design incorporated with BCI systems is capable of performing hand rehabilitation in a clinical setting as it obtains some level of accuracy in detecting patient intent to move and actuating in response. This design is low cost, and hence will lessen the economic burden for stroke survivors in a poor-resource country.
Spatially resolved spectroscopy of an impulse plasma for thin film deposition

Radially resolved emission measurements have been employed for a better understanding of plasma generated in a pulsed coaxial accelerator operating in a mixture of propane and butane under conditions which enable diamond-like layer deposition. The measurements were taken at two positions along the axis of symmetry of the discharge. Assuming the Boltzmann and Saha equilibrium, the emission from the plasma has been quantified. Abel-transformed radial profiles of the spectral lines of C I, C II and C III have been used to study radial changes in the concentration of excited neutral, singly and doubly ionized carbon, in the excitation temperature, in the ionization temperature and in the electron number density. Values of excitation and ionization temperatures and their radial profiles for a given axial position did not differ significantly. On the axis of symmetry of the discharge, the excitation temperature of C II and the electron density were found to reach values of about 29 000 K and 5 × 1017 cm−3, respectively. In addition, the relative densities of the C, C+ and C2+ species were evaluated, and hence the spatial inhomogeneous plasma structure with respect to the distribution of neutral and ionized fractions of carbon has been revealed and discussed in terms of deposition conditions.
A HPV16-related prognostic indicator for head and neck squamous cell carcinoma

Background The human papillomavirus (HPV) is emerging as an important risk factor in head and neck squamous cell carcinoma (HNSCC) patients. This has been observed particularly in the case of HPV16. The HPV16+ HNSCC subtype has distinct pathological, clinical, molecular, and prognostic characteristics. This study aimed to identify potential microRNAs (miRNAs) and their roles in HPV16+ HNSCC progression. Method miRNA, mRNA and the clinical data of 519 HNSCC and 44 HNSCC-negative samples were obtained from The Cancer Genome Atlas (TCGA) database. Differentially expressed miRNAs (DEMs) in HPV16-related HNSCC tissues with prognostic value were selected. DEM levels were assessed based on clinicopathological parameters and overall survival (OS). Target genes were also predicted and functional analysis based on Gene Set Enrichment Analysis (GSEA) were then performed. Results In HPV16+ HNSCC tissues, miR-99a-3p and miR-4746-5p were significantly upregulated. In contrast, miR-411-5p was shown to be downregulated. miR-99a-3phighmiR-411-5plowmiR-4746-5phigh expression could estimate improved OS and low frequent perineural invasion (PNI). Predicted target genes were enriched in cell growth, neuroepithelial cell differentiation, MAPK and FoxO signaling pathways. Epithelial mesenchymal transition (EMT) gene set and invasion related genes were downregulated in miR-99a-3phighmiR-411-5plowmiR-4746-5phigh HNSCC patients. Conclusion miR-99a-3p, miR-411-5p and miR-4746-5p might participate in HPV16+ HNSCC progression through EMT related pathways and affect prognosis.
Healthy, Housed, and Well-Fed: Exploring Basic Needs Support Programming in the Context of University Student Success

Meeting college students’ basic needs is the goal of a new set of student success initiatives that address students’ urgent food, housing, or financial hardships in an effort to help them remain and succeed in college. Focusing on one California public university, we describe one such basic needs program, identifying the students who participate, their hardships and services received, and their retention over time. Students presented with issues in four main areas: food insecurity, mental health, multiple severe hardships, and need for one-time supports. In general, participants were retained at lower rates than the campus average, which is to be expected given their severe hardships. However, those who enrolled in the Supplementation Nutrition Assistance Program (SNAP) were retained at higher rates, on par with or higher than university-wide retention. California has amended SNAP regulations to waive work requirements for low-income students, making it easier for college students to qualify.
