The interaction between organizational justice and job characteristics: Associations with work attitudes and employee health cross sectionally and over time
Year: 2015

The present study investigates to what extent main and interactive effects of overall organizational justice and job characteristics shape employees' work attitudes (organizational commitment, intention to stay) and health (mental health, somatic health) cross sectionally and after a period of one year. Questionnaire data from 429 Swedish accountants show that generally both organizational justice and job characteristics had main effects on all outcomes at both time points. Interactions between organizational justice and job characteristics were found for every job characteristic studied (demand, control, support) for both time points but mainly for intention to stay and somatic health. The results show that perceptions of organizational justice and job characteristics can have additive and multiplicative synergetic effects for work attitudes and employee health.
Efficient separation of free organic liquid mixtures based on underliquid superlyophobic coconut shell coated meshes
Year: 2020

The separation of multiphase liquid mixtures plays an important role in industrial production and environmental protection. The organic liquids (OLs) usually show approximate wettability on most of common materials owing to smaller surface tension. Therefore, the separation of OL mixtures is more difficult than the separation of oil/water mixtures. The current research on separation of OL mixtures is mainly through the covalent modification to precisely control the surface energy of materials, which is extremely complicated. Herein, a novel underliquid superlyophobic concept was presented for the separation of immiscible OL mixtures, which only depended on a relatively stable liquid repellent interface. Furthermore, the minimum system's free energy principle was used to explain this wetting behavior. Compared with the previous reports, the work does not involve in various low surface energy substances, thus it is facile, eco friendly and easily scale up. Thus, the study provides a general strategy to separate the OL mixtures for the product purification and environmental protection.
Corporate social responsibility and environmental performance: The mediating role of environmental strategy and green innovation
Year: 2020

This study investigates the influence of corporate social responsibility (CSR) on environmental performance, using data from 297 large manufacturing firms in Malaysia. Our results show that CSR has no direct significant influence on environmental performance, but is positively correlated to environmental strategy and green innovation, which again improve environmental performance, i.e. they significantly mediate between CSR and environmental performance. Our study offers a valuable model for general managers of manufacturing organizations and policymakers to manage CSR, environmental strategy, and green innovation in examining environmental performance. It can help to assist general managers of large manufacturing organizations to strengthen their internal resources like CSR, environmental strategy, and green innovation to enhance environmental performance.
EMPLOYMENT IN VS. EDUCATION FOR THE BIOECONOMY
Year: 2018

A number of employees is one of the basic indicators applied for identification of the economic relevance of an industry or an economic sector. Referring to nearly 18.6 million people employed in the 28 EU Member States within the bioeconomy in 2014, it can be stated that this a an economic sphere of significant importance in the European economy. The main aims of the study are to identify a scale of employment in the bioeconomy sector across EU Member States as well as to investigate tertiary education in bioeconomy based on the Polish experience in the Bioeconomy subject area group within the Euroleague for Life Sciences (ELLS) Data used included: (1) the data portal of agro economics modelling DataM of the Joint Research Centre of the European Commission, (2) CAWI research among students of WULS SGGW on their attitudes to the bioeconomy, (3) feedback of participants of the first summer school in bioeconomy coordinated by WULS SGGW. Research results display that the majority of Polish students did not meet the term of bioeconomy generally as well as at the university. There is also one very important students' comment which can describe their attitude: students of economic disciplines are not very much interested as they think that bioeconomy focuses on life sciences (bio) so it is not appropriate for them; students of different fields of life sciences are not very keen to study bioeconomy as according to them it focuses on economy (as in the name itself) Keywords: bioeconomy, employment, tertiary education, student Article DOI: http:/doi.org/10.15544/RD.2017.245
Relier la dynamique de la force de tension cellulaire avec l'architecture de l'actine
Year: 2018

La stabilite structurale et l'integrite mecanique sont des elements cles pour le bon fonctionnement et la preservation des systemes vivants complexes. Etant en interaction constante avec leur environnement et en ce qui concerne les intrants externes, de tels systemes doivent pouvoir faire face aux changements afin de prosperer. Ces entrees peuvent affecter le systeme dans son ensemble. Toute perturbation qui ne peut pas etre supportee mecaniquement par le systeme vivant entrainera un dysfonctionnement crucial ou, en fin de compte, sa mort. Le mecanisme responsable du maintien des conditions physiologiques du systeme a l'etat correct, malgre les variations environnementales, est identifie comme etant l'homeostasie. Plus precisement, le processus connu en mecanobiologie pour preserver l'equilibre mecanique approprie d'un systeme vivant est appele homeostasie tensionnelle.Il est important de noter que tout ce qui precede est vrai a la fois a l'echelle du comportement collectif des organismes complexes et jusqu'au niveau de la cellule unique. En fait, c'est en fait cette derniere petite echelle qui nous interesse. Les cellules font face a des perturbations mecaniques constantes de leur environnement et sont capables de repondre au maintien d'un etat mecanique interne relativement stable. L'existence de cet equilibre tensionnel interne est liee a un processus tres dynamique avec des boucles de retroaction constantes entre les machines contractiles biochimiques internes et les forces actives externes generees.Notre interet est de comprendre ce mecanisme dynamique en perturbant dynamiquement le systeme homeostatique tensionnel en etudiant son retour a l'equilibre.
Influences on intercultural classroom communication: student voices
Year: 2017

The case study is an attempt to understand how students experience intercultural classroom communication and what kind of competence they need to cope in intercultural classroom communication. The context is a supplementary course in English for university enrolment in Denmark. It is a multinational student body and all the students have finished a 3 year upper secondary school. The motive is to uncover challenges in intercultural classroom communication and to suggest tools to improve student learning outcome. The method applied is grounded theory focusing on observation of classroom communication, student questionnaires and semi structured interviews. The study shows different categories of students in relation to the students' intercultural communication and awareness. Some student categories are interested in intercultural classroom communication, whereas other student categories are less interested. The outcome of the study is related to theories of student behaviour and intercultural competence. Influences on intercultural classroom communication are student agendas in relation to learning and communication. Other influences are course description and the students' language skills. The study suggests tools to improve intercultural classroom communication. In the intercultural classroom, teachers can act as mediators across cultures and students can act as initiators of intercultural communication.
Photothermal efficiency enhancement of a nanofluid based direct absorption solar collector utilizing magnetic nano rotor
Venue: Energy Conversion and Management
Year: 2019

The concentration of nanofluids and receiver depth are important factors that significantly affect the efficiency of direct absorption solar collectors. In the current work, the impact of the two factors is investigated using reduced graphene oxide/ethanol glycol nanofluids. The results show uneven temperature distribution in the receiver at high nanofluid concentration or when the receiver is deep. To overcome these issues, a forced convection nanofluid absorption system using a Fe2O3 magnetic nanoparticles as the nano rotor, and driven by an external rotating magnetic field, was designed. The mechanism of the new system is compared with the conventional one in detail. The photothermal conversion efficiency of the binary nanofluids (a Fe2O3 graphene oxide/ethanol glycol nanofluids) in the new system reaches 56.8% which is 14.5% higher than non external rotating magnetic field nanofluids, for an RGO content of 0.007 wt% This enhancement is ascribed to two effects of a Fe2O3: improving the optical absorption capacity of binary nanofluids and acting as a nano rotor. The optimum photothermal conversion efficiency is achieved at an RGO/a Fe2O3 ratio of 3 in the current system.
Adjustment of milling, mash electroporation and pressing for the development of a PEF assisted juice production in industrial scale
Year: 2012

Pulsed electric field (PEF) assisted juice recovery from apple and carrot was performed. Different mash structures were subjected to PEF treatment at two different treatment intensity levels. Solid liquid separation was performed using four different systems: belt press, rack and cloth press, hydraulic filter press and decanter. The combination of milling and PEF treatment provided a method for the independent control of particle size and cell disintegration. An increase of juice yield after PEF treatment was found for apple mash in the range of 0 11% and for carrot mash in the range of 8 31% depending on mash structure and de juicing system. It was the aim of the study to investigate the interdependency of the aforementioned processing steps in order to develop adjustment concepts for the maximization of the juice yield increase by PEF and to evaluate the impact on related juice quality parameters. Industrial relevance Pulsed electric field (PEF) treatment of fruit and vegetable mashes and the resulting cell disintegration is a promising alternative to conventional enzymatic maceration or thermal disintegration to improve juice yields. PEF equipment is commercially available for industrial scale processing of fruit and vegetable mashes. Despite the uncomplicated technical implementation of the PEF system in the existing processing line, related processing steps such as milling and pressing need to be adjusted in order to maximize the beneficial PEF effect on the juice yield. The present study provides the basis for the required process analysis and optimization.
NEDD4 Negatively Regulates GITR via Ubiquitination in Immune Microenvironment of Melanoma
Venue: OncoTargets and therapy
Year: 2019

Melanoma is a common skin cancer that is usually associated with poor clinical outcomes. Recently, the immune checkpoint GITR has been identified as a promising target for immunotherapy of melanoma. In this study, we aimed to investigate the post translational regulation mechanism of GITR in melanoma.  Western blotting was used to evaluate the protein expression of NEDD4, GITR and Foxp3. Real time PCR (RT PCR) was performed to determine expression levels of NEDD4, GITR, Foxp3 and IL 2. Cell viability was detected by MTT assay. The ubiquitination of GITR was evaluated by immunoprecipitation. NEDD4 expression data and melanoma survival data were obtained from The Cancer Genome Atlas (TCGA) and cBioPortal databases.  We demonstrate that E3 ligase NEDD4 binds to GITR and mediates ubiquitination and degradation of GITR. Overexpression of NEDD4 inhibits anti tumor immunity mediated by T cells against melanoma cells. We also found that the expression of NEDD4 is increased in metastatic melanoma. High NEDD4 expression level is correlated with the poor prognosis of melanoma patients.  In summary, our findings demonstrated that E3 ligase NEDD4 mediates ubiquitination and degradation of GITR and suppresses T cell mediated killings on melanoma cells. Our work highlighted the E3 ligase NEDD4 as a novel prognosis biomarker and therapeutic target for melanoma.
Black, Asian and Minority Ethnic groups in England are at increased risk of death from COVID 19: indirect standardisation of NHS mortality data.
Venue: Wellcome open research
Year: 2020

International and UK data suggest that Black, Asian and Minority Ethnic (BAME) groups are at increased risk of infection and death from COVID 19. We aimed to explore the risk of death in minority ethnic groups in England using data reported by NHS England.  We used NHS data on patients with a positive COVID 19 test who died in hospitals in England published on 28th April, with deaths by ethnicity available from 1st March 2020 up to 5pm on 21 April 2020. We undertook indirect standardisation of these data (using the whole population of England as the reference) to produce ethnic specific standardised mortality ratios (SMRs) adjusted for age and geographical region.  The largest total number of deaths in minority ethnic groups were Indian (492 deaths) and Black Caribbean (460 deaths) groups. Adjusting for region we found a lower risk of death for White Irish (SMR 0.52; 95%CIs 0.45 0.60) and White British ethnic groups (0.88; 95%CIs 0.86 0.0.89) but increased risk of death for Black African (3.24; 95%CIs 2.90 3.62) Black Caribbean (2.21; 95%CIs 2.02 2.41) Pakistani (3.29; 95%CIs 2.96 3.64) Bangladeshi (2.41; 95%CIs 1.98 2.91) and Indian (1.70; 95%CIs 1.56 1.85) minority ethnic groups.  Our analysis adds to the evidence that BAME people are at increased risk of death from COVID 19 even after adjusting for geographical region. We believe there is an urgent need to take action to reduce the risk of death for BAME groups and better understand why some ethnic groups experience greater risk. Actions that are likely to reduce these inequities include ensuring adequate income protection (so that low paid and zero hours contract workers can afford to follow social distancing recommendations) reducing occupational risks (such as ensuring adequate personal protective equipment) reducing barriers in accessing healthcare and providing culturally and linguistically appropriate public health communications.
The SaveMyBike Project: ITS Technologies and Rewarding Policies to Improve Sustainable Mobility in Cities
Year: 2018

Private car mobility registers a high accident rate and, in addition, in 2014 in the EU 28, around 70% of the overall CO2 emissions from transport were generated by road mode. As a result, a modal shift of at least a part of passenger transport in urban areas, from private car to sustainable transport systems is desirable. Several policies have been adopted in the EU in this direction. The SaveMyBike project regards the development of a rewarding system for sustainable mobility based on an open source platform able to monitor systematically trips in the city, starting to integrate the platform with a service to incentive private bike use by means of UHF RFID systems, creating secure areas for bike parking and finding stolen bicycles. The real testing application to the Livorno case study from the beginning of 2018. Then, SaveMyBike project introduces four innovations: it's, for the first time, an open source rewarding platform, called GOOD_GO linked to an anti theft system for private bikes, it is applied to a whole city and it introduces a 'financially hot system' for municipalities able to find financial resource from bike services.
The Effects of Avatar Visibility on Behavioral Response with or without Mirror Visual Feedback in Virtual Environments
Venue: 2020 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)
Year: 2020

Existing studies have shown that increasing avatar visibility could not improve perceptual responses. With the recent advances of VR technology, full body tracking avatars have been adopted to social interactions and games with light weight head mounted displays. However, it is unknown about the effects of full body avatars on behavioral responses. Hence, in this study, we designed a full body avatar visibility with or without virtual mirror feedback, and investigated their effects on presence, embodiment, and task performance in a bow shooting game. This study provides initial results of using avatar visibility to enhance behavioral responses in virtual environments
Validation of predicted vibratory loads of a coaxial rotor at high advance ratios with wind tunnel test data
Year: 2016

The predictions of a comprehensive analysis based on UMARC are compared to experimental coaxial rotor results. The experiments cover a range of collective pitch angles from 2 to 10 advance ratios from 0:2 to 0:5, and lift offset from 0% to 20% The experimental model rotor system is a pair of hingeless coaxial rotors, with two blades each, and a first flap frequency of approximately 1:6/rev. It was tested in the Glenn L. Martin Wind Tunnel at the University of Maryland as isolated rotors and as a counter rotating coaxial rotor system The simulation is validated against coaxial performance and vibratory loads. The simulation captures increasing rotor efficiency with lift offset and advance ratio and also properly models 2/rev vibratory loads with advance ratio, lift offset, and rotor to rotor phase. The inversion of thrust between upper and lower rotor with advance ratio is identified.
Managemental Interventions to Reduce Heat Stress in Chickens
Year: 2020

Chickens are very sensitive to environmental temperature. Their growth, egg production and health are severely affected during extremes of weather conditions. Therefore, within the economically feasible limits, optimum temperature has to be provided to the poultry birds, in order to obtain optimal growth rate and returns from the farming entity. During the summer season, the chickens will need more special attention. Chickens have a much higher body temperature than other animals and humans. The average body temperature for a chicken normally will run at 102 103 degF. Their heart rate is normally 280 315 beats per minute. Another fact is a rooster will take around 18 20 breaths per minute while a hen has 30 35 breaths per minute. The average life span for an egg laying chicken is around 5 8 years for large breeds such as your Rhode Island Red's but have been known to live 20 years while broiler meat purpose birds only live up to 1 3 years. The summer heat can create more problems for chickens than cold weather. It's easy to see they are insulated well with many feathers. Chickens fluff up their feathers as many birds will do which traps air between the layers which keep them warm during cold weather. In hot weather they seek out shade. They lay down and spread their wings and bodies out to cool down. However, the provision of cold drinking water can ameliorate huge amount of stress from the chickens.
Fatigue Life Prediction of Commercial Dental Implant Using Analytical Approach and Verification by FEA
Year: 2018

Dental implants are nowadays commonly used as replacement for natural teeth when natural teeth get damaged due to injury, infection or old age. Despite high success rates of implantation, complications and failures of implants still occur. The aim of this study is to predict fatigue life of commercially available implant system using FEA and verification by analytical method. Implant is basically a mechanical screw made of titanium alloy Ti 6Al 4V with threads on its periphery. A three dimensional finite element model (FE model) of implant prosthesis (implant, abutment, fitting screw and crown) is modeled using linear isotropic material properties for implant, abutment, cortical bone and cancellous bone using commercial software code. Occlusal load (vertical and lateral) on teeth is applied as static load on the crown to find the stresses around implant bone interface. Analytical approach is used to predict fatigue life of implant. Good correlation is observed in analytical method and FEA results. The study is useful for better understanding of stress concentration location of implant systems. Guidelines for selecting the best implant can be suggested.
Ecological feedbacks stabilize a turf dominated ecosystem at the southern extent of kelp forests in the Northwest Atlantic
Venue: Scientific Reports
Year: 2019

Temperate marine ecosystems globally are undergoing regime shifts from dominance by habitat forming kelps to dominance by opportunistic algal turfs. While the environmental drivers of shifts to turf are generally well documented, the feedback mechanisms that stabilize novel turf dominated ecosystems remain poorly resolved. Here, we document a decline of kelp Saccharina latissima between 1980 and 2018 at sites at the southernmost extent of kelp forests in the Northwest Atlantic and their replacement by algal turf. We examined the drivers of a shift to turf and feedback mechanisms that stabilize turf reefs. Kelp replacement by turf was linked to a significant multi decadal increase in sea temperature above an upper thermal threshold for kelp survival. In the turf dominated ecosystem, 45% of S. latissima were attached to algal turf rather than rocky substrate due to preemption of space. Turf attached kelp required significantly (2 to 4 times) less force to detach from the substrate, with an attendant pattern of lower survival following 2 major wave events as compared to rock attached kelp. Turf attached kelp allocated a significantly greater percentage of their biomass to the anchoring structure (holdfast) with a consequent energetic trade off of slower growth. The results indicate a shift in community dominance from kelp to turf driven by thermal stress and stabilized by ecological feedbacks of lower survival and slower growth of kelp recruited to turf.
EmotionMeter: A Multimodal Framework for Recognizing Human Emotions
Venue: IEEE Transactions on Cybernetics
Year: 2019

In this paper, we present a multimodal emotion recognition framework called EmotionMeter that combines brain waves and eye movements. To increase the feasibility and wearability of EmotionMeter in real world applications, we design a six electrode placement above the ears to collect electroencephalography (EEG) signals. We combine EEG and eye movements for integrating the internal cognitive states and external subconscious behaviors of users to improve the recognition accuracy of EmotionMeter. The experimental results demonstrate that modality fusion with multimodal deep neural networks can significantly enhance the performance compared with a single modality, and the best mean accuracy of 85.11% is achieved for four emotions (happy, sad, fear, and neutral) We explore the complementary characteristics of EEG and eye movements for their representational capacities and identify that EEG has the advantage of classifying happy emotion, whereas eye movements outperform EEG in recognizing fear emotion. To investigate the stability of EmotionMeter over time, each subject performs the experiments three times on different days. EmotionMeter obtains a mean recognition accuracy of 72.39% across sessions with the six electrode EEG and eye movement features. These experimental results demonstrate the effectiveness of EmotionMeter within and between sessions.
