Genetics in TNF TNFR pathway: A complex network causing spondyloarthritis and conditioning response to anti TNFa therapy
Venue: PloS one
Year: 2018

We investigated whether polymorphisms (SNPs) in the promoter region of TNFA, or in the autoinflammatory TNFRSF1A and MEFV genes, concur with HLA B27 in enhancing the risk of Spondyloarthritis (SpA) and/or in predicting the response to anti TNFa treatment.  controls and 137 SpA (82 with Psoriatic Arthritis PsA and 55 with Ankylosing Spondylitis AS; 98/137 under TNFa inhibitor therapy) from the Veneto Region (Italy) were studied. TNFA polymorphisms 1031T>C; 857C>T; 376G>A; 308G>A; 238G>A) and HLA B27 were assayed by RT PCR. Direct sequencing of MEFV (exons 2,3,5 and 10) and TNFRSF1A (exons 2,3,4 and 6) genes were performed.  HLA B27 was associated with AS (kh2 120.1; p 0.000) Only the TNFA 1031T>C was singly associated with SpA, and the haplotype C/G, resulting from 1031T>C/ 308G>A combination, was significantly associated with a reduced risk of SpA (OR: 0.67, CI: 0.46 0.97; p 0.035) Two SNPs were identified in TNFRSF1A, the R92Q (Minor allele frequency MAF 0.034) and c.625+10A>G (MAF 0.479) None of them was associated with SpA (p>0.05) The TNFRSF1A c.625+10 G allele was associated with late response to anti TNFa therapy (p 0.031) Twenty one SNPs were identified in MEFV gene, 10 with a known potential functional significance. Variant alleles were extremely rare in our population (MAF<0.025) except for R202Q (MAF 0.27) None was associated with SpA diagnosis (p>0.05) Conclusion TNFRSF1A and MEFV gene SNPs are not associated with SpA in the North East of Italy. AS risk appears to depend not only on HLA B27, but also on the protective TNFA haplotype 1031C/ 308G. The TNFRSF1A c.625+10A>G impacts on the response to anti TNFa therapy.
EFL Teachers as Designers of Ubiquitous Learning Experiences
Venue: Arab World English Journal
Year: 2019

Ubiquitous learning, also known as U learning, refers to the learner's ability to learn at any place at any time. This paper argues that U learning represents a new perspective in terms of pedagogy. The main contributor to this process is foremost the teacher, who has to adhere to the everchanging language learning/teaching scenery. This study aims at setting the fundamentals of materials development at the intersection of two major areas of contemporary education, namely the needs of the 'net generation' students and the educational potential of the evolving social web and digital technology. It seeks to answer the following questions: What is digital technology and how does it lead to U learning? What is web 2.0 and how does it affect classroom pedagogy, practice, and the design of quality teaching/learning materials? How does it help teachers improve their practice and materials development procedures? And how can teachers transform today's innovative technology into ubiquitous learning experiences, promoting learner autonomy, regardless of any geographical or institutional boundaries? We will illustrate the whole procedure with a framework for web 2.0 integration that identifies the crucial features underpinning the extramural, ubiquitous learning experiences, in which learners can engage.
Feeding humanity through global food trade
Year: 2014

The recent intensification of international trade has led to a globalization of food commodities and to an increased disconnection between human populations and the land and water resources that support them through crop and livestock production. Several countries are not self sufficient and depend on imports from other regions. Despite the recognized importance of the role of trade in global and regional food security, the societal reliance on domestic production and international trade remains poorly quantified. Here we investigate the global patterns of food trade and evaluate the dependency of food security on imports. We investigate the relationship existing between the trade of food calories and the virtual transfer of water used for their production. We show how the amount of food calories traded in the international market has more than doubled between 1986 and 2009, while the number of links in the trade network has increased by more than 50% Likewise, global food production has increased by more than 50% in the same period, providing an amount of food that is overall sufficient to support the global population at a rate of 2700 3000 kcal per person per day. About 23% of the food produced for human consumption is traded internationally. The water use efficiency of food trade (i.e. food calories produced per unit volume of water used) has declined in the last few decades. The water use efficiency of food production overall increases with the countries' affluence; this trend is likely due to the use of more advanced technology.
Desensitization of Axial Compressor Performance and Stability to Tip Clearance Size
Year: 2015

This paper presents a computational and analytical study to identify and elucidate fundamental flow features associated with the desensitization of performance and aerodynamic stability of an axial compressor rotor to tip clearance change. Parametric studies of various design change on a baseline double circular arc axial rotor led to the identification of two flow features associated with reducing sensitivity to tip clearance, namely high incoming meridional momentum in the tip region and reduction/elimination of double tip leakage. Numerical experiments were subsequently performed on the baseline rotor geometry to validate these two flow features and explain the associated flow physics by variations in incoming meridional momentum and pitch size. Finally, two designs were proposed, namely full forward chordwise sweep and partially low stagger angle, to exploit these flow features. The results indicated that both designs produce the intended flow effects and exhibit lower performance and aerodynamic stability sensitivity to tip clearance.

Light Induced Reversible Control of Ferroelectric Polarization in BiFeO3.
Venue: Advanced materials
Year: 2018

Manipulation of ferroic order parameters, namely (anti )ferromagnetic, ferroelectric, and ferroelastic, by light at room temperature is a fascinating topic in modern solid state physics due to potential cross fertilization in research fields that are largely decoupled. Here, full optical control, that is, reversible switching, of the ferroelectric/ferroelastic domains in BiFeO3 thin films at room temperature by the mediation of the tip enhanced photovoltaic effect is demonstrated. The enhanced short circuit photocurrent density at the tip contact area generates a local electric field well exceeding the coercive field, enabling ferroelectric polarization switching. Interestingly, by tailoring the photocurrent direction, via either tuning the illumination geometry or simply rotating the light polarization, full control of the ferroelectric polarization is achieved. The finding offers a new insight into the interactions between light and ferroic orders, enabling fully optical control of all the ferroic orders at room temperature and providing guidance to design novel optoferroic devices for data storage and sensing.

Is body dissatisfaction changing across time? A cross temporal meta analysis.
Venue: Psychological bulletin
Year: 2017

It remains unclear whether body dissatisfaction, a widely recognized predictor of eating related pathologies and depressive symptomatology, is consistent across cohorts and time. This question is important to investigate because dominant theories propose that sociocultural influences, which may fluctuate, play an important role in the development of body dissatisfaction. Previous efforts for tracking body dissatisfaction across cohorts and time are limited by relying on data from a single institution or using assessments that lack psychometric support across genders. In this study, we utilized cross temporal meta analyses to examine changes in 2 dimensions of body dissatisfaction: thinness oriented dissatisfaction as assessed with the Eating Disorder Inventory Body Dissatisfaction subscale (data available across 31 years from 326 unique samples, n 100,228 participants) and muscularity oriented dissatisfaction as measured with the Drive for Muscularity Scale (data available across 14 years from 117 unique samples, n 23,575 participants) Results revealed a significant interaction between year of study and gender in predicting thinness oriented dissatisfaction: girls and women scored higher than boys and men consistently (ds 0.51 1.17) although only girls' and women's scores decreased gradually across time (d 0.49) Boys and men scored higher than girls and women on muscularity oriented dissatisfaction (d 1.72) with no significant changes across time. These patterns remained when controlling for age and geographic location. Overall, these findings highlight the importance of considering multiple dimensions of body dissatisfaction in research and offer evidence that sociocultural shifts in body acceptance and diversity may be countering thinness related pressures for girls and women.
Prevalence and Antimicrobial Resistance of Salmonella from Antibiotic Free Broilers During Organic and Conventional Processing.
Venue: Journal of food protection
Year: 2020

Salmonella is one of the top causes for bacterial foodborne infections in the United States, emphasizing the importance of controlling this pathogen for protecting public health. Poultry and poultry products are commonly associated with Salmonella, and interventions during production and processing are necessary to manage the risk of infection due to consumption of poultry products. In recent times, the demand for organic and antibiotic free poultry has increased owing to consumer perceptions and concerns of increasing prevalence of antimicrobial resistant (AMR) pathogens. However, the microbiological effect of these management practices is not clear. This study was conducted to determine the difference in the AMR of Salmonella isolated from poultry processed conventionally and organically. Fecal samples, carcass rinses, and environmental samples were collected over 1 year and analyzed for the prevalence of Salmonella and AMR. Results of this experiment showed that organic chickens were associated with statistically higher levels of Salmonella during early processing steps. However, no difference in Salmonella prevalence was observed between organic and conventional carcasses postchill. In addition, for most antimicrobial agents tested, prevalence of AMR Salmonella in conventional processing was lower in this study than was reported by the National Antimicrobial Resistance Monitoring System for chickens at slaughter. These observations indicate that organic methods may introduce greater risk of Salmonella contamination; however, proper interventions during processing can abate this risk. In addition, this study supports the assertion that raising chickens without the use of antibiotics may result in lower prevalence of AMR Salmonella.

Corporate Social Responsibility and Human Resource Management: Towards Sustainable Business Organizations
Year: 2020

Today's organizations are immersed in a global market, where any detail can provide a competitive advantage over rival companies and condition their sustainability. Corporate Social Responsibility and Human Resource Management have become very powerful tools within companies. However, the potential, development, and measurement of Corporate Social Responsibility (CSR) and Human Resource Management (HRM) have not been sufficiently explored. The literature has developed multiple case studies on CSR and HRM and has studied the combination of both factors and their link to economic, environmental, and social sustainability, but has not yet found a solid basis from which to address the new functionality of CSR, HRM, and sustainable business management. This work aims to investigate trends in scientific production related to Corporate Social Responsibility and Human Resource Management. Bibliometric techniques and SciMAT software have been used for this purpose. A total of 314 articles from Web of Science (WOS) indexed journals were analyzed. The results obtained confirm that the interest in the study of these concepts has grown exponentially in the last decade. It should be noted that the definitions of CSR and HRM, and even the relationship between the two, continue to be subject to multiple interpretations. The contribution of this work lies in the fact that, through the longitudinal analysis carried out, light is shed on the groups of issues that emerge with special projection, such as green management, stakeholders, commitment, competitive advantage, satisfaction, performance, sustainability, or research methods analysis, and which must continue to be explored in order to respond to the demands that business organizations have in this respect, and to help the total integration of the different approaches related to CSR and HRM.
Control of clathrin mediated endocytosis by NIMA family kinases
Year: 2019

Endocytosis, the process by which cells internalize plasma membrane and associated cargo, is regulated extensively by posttranslational modifications. Previous studies suggested the potential involvement of scores of protein kinases in endocytic control, of which only a few have been validated within their native context. Here we show that the conserved NIMA related kinases NEKL 2/NEK8/9 and NEKL 3/NEK6/7 (the NEKLs) control clathrin mediated endocytosis in C. elegans. Loss of NEKLs leads to clathrin mislocalization and to a dramatic reduction in clathrin mobility at the apical membrane. Strikingly, reducing the levels of active AP2, the major clathrin adapter complex, rescues nekl mutant defects, whereas increased levels of active AP2 exacerbate nekl defects. Moreover, NEKL inhibition alleviates defects associated with reduced AP2 activity, attesting to the tight link between NEKL and AP2 functions. We also show that NEKLs are required for the clustering and internalization of membrane cargo and that human NEKs rescue defects in nekl mutant worms.
Bayesian Active Learning for Wearable Stress and Affect Detection
Venue: ArXiv
Year: 2020

In the recent past, psychological stress has been increasingly observed in humans, and early detection is crucial to prevent health risks. Stress detection using on device deep learning algorithms has been on the rise owing to advancements in pervasive computing. However, an important challenge that needs to be addressed is handling unlabeled data in real time via suitable ground truthing techniques (like Active Learning) which should help establish affective states (labels) while also selecting only the most informative data points to query from an oracle. In this paper, we propose a framework with capabilities to represent model uncertainties through approximations in Bayesian Neural Networks using Monte Carlo (MC) Dropout. This is combined with suitable acquisition functions for active learning. Empirical results on a popular stress and affect detection dataset experimented on a Raspberry Pi 2 indicate that our proposed framework achieves a considerable efficiency boost during inference, with a substantially low number of acquired pool points during active learning across various acquisition functions. Variation Ratios achieves an accuracy of 90.38% which is comparable to the maximum test accuracy achieved while training on about 40% lesser data.

Fostering Flexibility in the New World of Work: A Model of Time Spatial Job Crafting
Venue: Front. Psychol.
Year: 2019

In today's "new world of work," knowledge workers are often given considerable flexibility regarding where and when to work (i.e. time spatial flexibility) and this has become a popular approach to redesigning work. Whilst the adoption of such practices is mainly considered a top down approach to work design, we argue that successful utilization of time spatial flexibility requires proactivity on the part of the employee in the form of time spatial job crafting. Previous research has demonstrated that time spatial flexibility can have both positive and negative effects on well being, performance, and work life balance; yet remains mute about the underlying reasons for this and how employees can handle the given flexibility. Drawing on research from work design, we posit that in order for employees to stay well and productive in this context, they need to engage in time spatial job crafting (i.e. a context specific form of job crafting that entails reflection on time and place) which can be considered a future work skill. We propose a theoretical model of time spatial job crafting in which we discuss its components, shed light on its antecedents, and explain how time spatial job crafting is related to positive work outcomes through a time/spatial demands fit.
