Online food delivery services and behavioural intention a test of an integrated TAM and TPB framework
Venue: British Food Journal
Year: 2020

PurposeThis research leverages an integrated framework that uses the technology acceptance model (TAM) and the theory of planned behaviour (TPB) to analyse the main drivers of users' intention to use food delivery apps. The purpose of this paper is to investigate the consumer's willingness to adopt online food delivery (OFD) using the models' constructs and extend them to consider food choices, convenience, trust and the effect of the perceived risks related to the coronavirus disease 2019 (COVID 19) pandemic as contextual factors. to examine the data. The final sample consists of 425 people in Italy. authors have found that combining the TAM and the TPB provides a valid and significant model that can be used to understand OFD users' behavioural intentions. Moreover, the results show that subjective norms have a stronger effect on behavioural intentions than the personal attitude and that trustworthiness and the perception of risks related to COVID 19 have different effects. Accordingly, the authors derive several theoretical and managerial implications from these results.valueThis research contributes to the current debate on consumer behaviour in the OFD context. Only a few studies have integrated the TAM and TPB models in this context. This paper sheds light on the factors useful in predicting people's choice to buy food via OFD. Furthermore, it highlights the key role of some contextual factors and subjective norms over more technical ones.
High fiber media as the most efficient substrates for Pleurotus florida culture
Year: 2011

Implementation of agricultural residues for oyster mushroom culture has been accepted world wide. In this study, we used wheat straw, barley straw, maize stem residue, and lawn residue as substrates coupled with wheat bran, rice bran and soybean powder as complements for the growth of P. florida. Wheat and barley straws which contained a high fiber and C/N ratio had the best growth period, fruiting body weight, yield, and biological efficiency. Assessment of substrate and complement combinations indicated that the lowest growth period was obtained from barley straw enriched with rice bran (24.67 day) However the highest fruiting body number (36.33) fruiting body weight (31.17 g) yield (1039 g) and biological efficiency (207.8 belonged to wheat straw complemented by either wheat or rice bran. In conclusion, the highest fruiting body weight, yield, and biological efficiency was achieved by implementation of composts in which high fiber substrates and complements were combined.
On Fast algorithms for orthogonal Tucker decomposition
Venue: 2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Year: 2014

We propose algorithms for Tucker tensor decomposition, which can avoid computing singular value decomposition or eigenvalue decomposition of large matrices as in the work horse higher order orthogonal iteration (HOOI) algorithm. The novel algorithms require computational cost of O(I<sup>3</sup>R) which is cheaper than O(I<sup>3</sup>R IR<sup>4</sup> R<sup>6</sup> of HOOI for multilinear rank (R, R, R) tensors of size I x I x I.
Effects of triclosan on antioxidant and apoptosis related genes expression in the gill and ovary of zebrafish
Venue: Experimental animals
Year: 2019

Triclosan (TCS) is a broad spectrum antibacterial and anti fungal agent used in a broad variety of personal care products (PCPs) throughout the world. However, the molecular mechanism of TCS's effects on the gill and ovary of fish is not clear. In this study, the effects of TCS exposure on expression of antioxidant and apoptosis related genes were investigated in the gill and ovary of zebrafish (Danio rerio) Zebrafish were exposed to 0, 17, 34, or 68 ug/l TCS for 42 days. Antioxidant related genes (SOD, GPx1a, CAT, sMT B, and MT 2) in the gill were significantly downregulated in the 34 (except GPx1a) and 68 ug/l TCS groups, and these genes (except MT 2) in the ovary were significantly downregulated in the 68 ug/l TCS group. Apoptosis related gene (Bax and p53) expression level in the gill were significantly downregulated in the 68 ug/l TCS group, while the ratios of BCL 2 to Bax and MDM2 gene were significantly upregulated. The Bax gene in the ovary was significantly upregulated in the 34 and 68 ug/l TCS groups, while the ratio of BCL 2 to Bax was significantly downregulated. Moreover, the p53 gene in the ovary in the 34 ug/l TCS group was significantly upregulated. In addition, the MDA contents in the gill in the 34 and 68 mg/l TCS treated groups and in the ovary in 68 mg/l group were significantly increased. The results showed that the higher dose of TCS might cause oxidative damage in the gills and ovaries and accelerate ROS dependent ovary apoptosis in zebrafish.

Stable and High Performance Flexible ZnO Thin Film Transistors by Atomic Layer Deposition.
Venue: ACS applied materials interfaces
Year: 2015

Passivation is a challenging issue for the oxide thin film transistor (TFT) technologies because it requires prolonged high temperature annealing treatments to remedy defects produced in the process, which greatly limits its manufacturability as well as its compatibility with temperature sensitive materials such as flexible plastic substrates. This study investigates the defect formation mechanisms incurred by atomic layer deposition (ALD) passivation processes on ZnO TFTs, based on which we demonstrate for the first time degradation free passivation of ZnO TFTs by a TiO2/Al2O3 nanolaminated (TAO) film deposited by a low temperature (110 degC) ALD process. By combining the TAO passivation film with ALD dielectric and channel layers into an integrated low temperature ALD process, we successfully fabricate flexible ZnO TFTs on plastics. Thanks to the exceptional gas barrier property of the TAO film (water vapor transmission rate (WVTR)<10( 6) g m( 2) day( 1) as well as the defect free nature of the ALD dielectric and ZnO channel layers, the TFTs exhibit excellent device performance with high stability and flexibility: field effect mobility>20 cm2 V( 1) s( 1) subthreshold swing<0.4 V decade( 1) after extended bias stressing >10,000 s) air storage >1200 h) and bending (1.3 cm radius for 1000 times)
Convergence Rates for Distributed Stochastic Optimization Over Random Networks
Venue: 2018 IEEE Conference on Decision and Control (CDC)
Year: 2018

We establish the $O(\frac{1}{k} convergence rate for distributed stochastic gradient methods that operate over strongly convex costs and random networks. The considered class of methods is standard each node performs a weighted average of its own and its neighbors' solution estimates (consensus) and takes a negative step with respect to a noisy version of its local function's gradient (innovation) The underlying communication network is modeled through a sequence of temporally independent identically distributed (i.i.d. Laplacian matrices such that the underlying graphs are connected on average; the local gradient noises are also i.i.d. in time, have finite second moment, and possibly unbounded support. We show that, after a careful setting of the consensus and innovations potentials (weights) the distributed stochastic gradient method achieves a (order optimal) $O(\frac{1}{k} convergence rate in the mean square distance from the solution. To the best of our knowledge, this is the first order optimal convergence rate result on distributed strongly convex stochastic optimization when the network is random and the gradient noises have unbounded support. Simulation examples confirm the theoretical findings.
Few Shot Adaptation for Multimedia Semantic Indexing
Venue: ACM Multimedia
Year: 2018

We propose a few shot adaptation framework, which bridges zero shot learning and supervised many shot learning, for semantic indexing of image and video data. Few shot adaptation provides robust parameter estimation with few training examples, by optimizing the parameters of zero shot learning and supervised many shot learning simultaneously. In this method, first we build a zero shot detector, and then update it by using the few examples. Our experiments show the effectiveness of the proposed framework on three datasets: TRECVID Semantic Indexing 2010, 2014, and ImageNET. On the ImageNET dataset, we show that our method outperforms recent few shot learning methods. On the TRECVID 2014 dataset, we achieve 15.19~ and 35.98~ in Mean Average Precision under the zero shot condition and the supervised condition, respectively. To the best of our knowledge, these are the best results on this dataset.
Moving toward risk based deposit insurance premiums in the European Union: the case of Spain
Year: 2014

This article provides a scenario based analysis of how the European Union proposal for a new funding model for deposit insurance systems (DISs) would affect the Spanish banking sector. We examine the risk profiles of commercial banks, savings banks and credit cooperatives over the period 2007 to 2011 and compare the contributions to the deposit insurance fund (DIF) under the current flat rate regime with those that would have occurred under the new risk sensitive system. We find that a risk based scheme could provide an incentive for sound management by reducing the premiums for credit institutions with better risk profiles. We also conclude that the proposed reform may help to mitigate the moral hazard associated with larger credit institutions.
"You are Dead, but You are Not" Social medium (Facebook) is the message in grieving and continuing bonds
Year: 2020

Today, one may no longer alive but his social networking sites (SNS) account will still live on. Empirical studies on death and SNS started since 2004 covering issues on grief, bereavement, mourning, relational continuity functions of SNS, and digital legacy. Majority of them applied content and discourse analyses on SNS messages directed to or related to the deceased. Applying McLuhan's aphorism medium is the message, researcher focused on the interplay among forms and functions of Facebook (FB) as a medium and message that mediates grief and the bereaved persons who are communicators that decided to grieve on FB. This research adopts grounded theory approach where in depth interviews with 10 bereaved persons who maintain relational continuity with their deceased loved ones through FB were conducted. The conclusions are drawn to prove that bereaved users preferred to engage in a transcoporeal mediated communication with deceased for continuing bonds due to four main reasons the deceased are perceived "dead but they are not" maintaining relational continuity via FB is essential to "finish their unfinished business" they felt aided and embraced when adopting "FB the Public Platform for Private Grief" and they imagined a mutual communication based on "past experience and religious belief" The mediated transcopereal communication (TcC) is enabled because the social medium (FB) is the message.
On the role of context in business process management
Year: 2016

We emphasize the importance of going beyond a one size fits all approach to BPM.We suggest a comprehensive consideration of contextual factors in BPM.We propose a framework to identify BPM contexts along four dimensions. Business Process Management (BPM) has proven successful to help organizations improve and innovate, and its application has grown in scope and context. One essential problem related to this development is that the BPM body of knowledge does not account for a broader variety of business contexts. On the contrary, most approaches, methods, or models in BPM suggest one way forward, and we recognize that BPM projects following a one size fits all approach are prone to fail, since they do not sufficiently consider situational requirements. In this viewpoint article, we argue that BPM needs to be contextual in order for projects to be most efficient and effective. We observe a lack of research on how to identify and characterize business contexts relevant for tailoring the right BPM approach. Therefore, we examine contextual factors that influence BPM and propose a framework to identify the context in which BPM is applied. We define context in BPM as situational factors related to goal process organization and environment dimensions. Our viewpoint article not only creates awareness for contextual BPM, it also intends to stimulate research on the role of context in BPM and to help practitioners better understand the specific business context in which BPM initiatives are applied.
Research on The Effect of Service Recovery Quality on Customer Repurchase Intention in Online Shopping
Year: 2020

This article applies the theory of service recovery in traditional industries to the online shopping environment, taking the quality of service recovery as the independent variable, customer repurchase intention as the dependent variable, and consumer sentiment as the intermediary variable, to study the model of the impact of service recovery quality on customers' repurchase intention. Empirical research found that in the context of service failures, the service recovery quality will positively affect customers' repurchase intentions; Customers' emotions are related to the quality of service recovery. The higher the quality of service recovery, the more likely it is for customers to have positive emotions. Customers' emotions play an intermediary role in the process of service recovery quality affecting customers' repurchase intentions.
Childhood Trauma, DNA Methylation of Stress Related Genes, and Depression: Findings From Two Monozygotic Twin Studies
Venue: Psychosomatic medicine
Year: 2018

DNA methylation has been associated with both early life stress and depression. This study examined the combined association of DNA methylation at multiple CpG probes in five stress related genes with depressive symptoms and tested whether these genes methylation mediated the association between childhood trauma and depression in two monozygotic (MZ) twin studies.  The current analysis comprised 119 MZ twin pairs (84 male pairs [mean 55 years] and 35 female pairs [mean 36 years] Peripheral blood DNA methylation of five stress related genes (BDNF, NR3C1, SLC6A4, MAOA, and MAOB) was quantified by bisulfite pyrosequencing or 450K BeadChip. We applied generalized Poisson linear mixed models to examine the association between each single CpG methylation and depressive symptoms. The joint associations of multiple CpGs in a single gene or all five stress related genes as a pathway were tested by weighted truncated product method. Mediation analysis was conducted to test the potential mediating effect of stress gene methylation on the relationship between childhood trauma and depressive symptoms.  Multiple CpG probes showed nominal individual associations, but very few survived multiple testing. Gene based or gene set approach, however, revealed significant joint associations of DNA methylation in all five stress related genes with depressive symptoms in both studies. Moreover, two CpG probes in the BDNF and NR3C1 mediated approximately 20% of the association between childhood trauma and depressive symptoms.  DNA methylation at multiple CpG sites are jointly associated with depressive symptoms and partly mediates the association between childhood trauma and depression. Our results highlight the importance of testing the combined effects of multiple CpG loci on complex traits and may unravel a molecular mechanism through which adverse early life experiences are biologically embedded.
Inconsistencies in the behavioural effects of consumer ethnocentrism: The role of brand, product category and country of origin
Year: 2017

Despite the well established impact of consumer ethnocentrism (CET) on purchase intentions, extant literature offers limited evidence on actual purchase behaviour. The purpose of this paper is to address the gap by investigating the factors underlying variations in CET behaviour using reported brand purchases. Product category, product cost and visibility, brand and country of origin (COO) of purchased products are investigated for their impact on the differences in the behavioural effects of CET.  This study uses survey data collected in the USA from a sample of 468 consumers. Self reported brand purchases are used and involve ten product categories, 432 brands, and 22 countries of origin. Logistic regressions for repeated measures are used to test the hypotheses formulated.  The results confirm that product category is an important determinant of the behavioural effects of CET. CET also has a significant impact on purchases of the most expensive product categories rather than frequently purchased convenient items. Contrary to existing empirical evidence, cultural similarity does not mitigate the negative effects of CET and product visibility does not strengthen the behavioural effect of CET.  The study results should enhance managers' understanding of the determinants of ethnocentric behaviour. The results caution managers about the value of self reported measures and indicate that product features other than COO may be more effective in mitigating the negative effects of CET.  This study contributes to extant literature on CET and COO by investigating, for the first time, the problem of inconsistent predictions of purchase behaviour in the context of foreign vs domestic brands. For this purpose, the study adopted a novel methodological approach to investigate actual brand purchases.
?Cuantos somos? Una historia de los censos civiles y de la organizacion estadistica en Colombia en la primera mitad del siglo XX
Year: 2017

Este articulo estudia el proceso de configuracion de las estadisticas censales en la primera mitad del siglo XX en Colombia. Se senalan las singularidades de la produccion y de los usos de estas cifras, y se describen los problemas que enfrento el Estado colombiano para producir estadisticas demograficas con caracter cientifico y fiables, como imperativo de la modernidad. El analisis de la documentacion mostro que los censos de 1905, 1912 y 1918 buscaron cuantificar principalmente la poblacion masculina con derecho al voto y apta para el servicio militar. Ademas, se pusieron en evidencia la fragilidad administrativa de los servicios de estadistica oficial y la participacion de expertos internacionales en la elaboracion de los censos posteriores.
RadioMic: Sound Sensing via mmWave Signals
Venue: ArXiv
Year: 2021

Voice interfaces has become an integral part of our lives, with the proliferation of smart devices. Today, IoT devices mainly rely on microphones to sense sound. Microphones, however, have fundamental limitations, such as weak source separation, limited range in the presence of acoustic insulation, and being prone to multiple side channel attacks. In this paper, we propose RadioMic, a radio based sound sensing system to mitigate these issues and enrich sound applications. RadioMic constructs sound based on tiny vibrations on active sources (e.g. a speaker or human throat) or object surfaces (e.g. paper bag) and can work through walls, even a soundproof one. To convert the extremely weak sound vibration in the radio signals into sound signals, RadioMic introduces radio acoustics, and presents training free approaches for robust sound detection and high fidelity sound recovery. It then exploits a neural network to further enhance the recovered sound by expanding the recoverable frequencies and reducing the noises. RadioMic translates massive online audios to synthesized data to train the network, and thus minimizes the need of RF data. We thoroughly evaluate RadioMic under different scenarios using a commodity mmWave radar. The results show RadioMic outperforms the state of the art systems significantly. We believe RadioMic provides new horizons for sound sensing and inspires attractive sensing capabilities of mmWave sensing devices.
