The Impact of Fixed and Mobile Telephones on Economic Growth in Algeria during the Period from 1963 to 2015
Venue: Advances in Economics and Business
Year: 2019

Communication is considered as an inevitable consequence of any development policy, whether economic or social, and among the various types of communication, telecommunication representing one of the irreplaceable infrastructure for any society. The demand on these services is increasing, from a simple telephone line to the establishment an information transmission network that dominates the different substrates of conversion, cable, fiber optic, satellite, etc. The telecommunications sector at Algeria has been monopolized by the state and has suffered greatly in response to the growing demand for telephone lines. But things have changed thanks to the new law of the sector, which opened the doors to private investors after thirty eight years; the State has licensed the private sector, and led to increased supply in this area. This article aims to study the causal relationship between GDP and telecommunications across the Algerian fixed and mobile telephones from 1963 to 2015. The empirical analysis moves by steps to test chronological series characteristics by using the Phillips perron (PP) tests, the Johansen cointegration test, and the Vector Error Correction Model short term (VECM) ending with the Granger causality test. The results showed that the coefficient is statistically significant for the VECM test, and the Granger causality test that has showed a unidirectional causal relationship between variables.
The Effects of Ownership Structure and Intragroup Loans on Leverage: Evidence from Family Firms in Chile
Year: 2017

This article examines the effects of family control and pyramidal ownership on firms' capital structure decisions. After studying a sample of listed family and nonfamily firms in Chile, we find that families take a conservative approach to debt and financial risk exposure. We test the hypothesis that family firms restrict the use of debt in order to avoid the monitoring role of creditors, which could limit their enjoyment of the private benefits of control. In keeping with this hypothesis, we find a U shaped relationship between leverage and the degree of pyramidal ownership that is more pronounced among family firms than nonfamily firms. We do not find any evidence that is consistent with the hypothesis that family controlled firms have low leverage ratios due to their access to internal capital markets. In fact, conversely, we find that listed family firms provide more loans to related companies than comparable nonfamily firms.

A Randomized Controlled Trial of Fractional Laser Therapy and Dermabrasion for Scar Resurfacing
Venue: Dermatologic surgery official publication for American Society for Dermatologic Surgery [et al.
Year: 2012

Dermabrasion has been the standard resurfacing procedure for postsurgical scars, but recovery can be long. Fractionated carbon dioxide (CO2) laser is a safe, effective tissue resurfacing modality, but no prospective trial has compared its safety or efficacy with that of dermabrasion for postsurgical scar resurfacing.  To compare the safety and efficacy of single treatment fractional photothermolysis with that of single treatment dermabrasion for postsurgical scar resurfacing on the face.  A split scar method was used to compare fractionated CO2 laser and diamond fraise dermabrasion on postsurgical scars of the face. Primary endpoint was safety at day 0, 1 week, and 1 month. Secondary endpoint was efficacy at 3 months as measured by blinded evaluation of standardized photographs.  Safety data revealed that there was less erythema (p .001) and bleeding (p .001) at day 0, less erythema (p .01) and edema (p .046) at 1 week, and a trend toward less erythema at 1 month (p .06) with fractionated CO2. Efficacy data at 3 months revealed equivalent scar improvements (p .77)  CO2 laser therapy should be considered a safe alternative for surgical scar resurfacing on the face. The safety profile exceeds that of dermabrasion, and it has a quicker clinical recovery and equivalent cosmetic efficacy.
Male Adolescents' Gender Attitudes and Violence: Implications for Youth Violence Prevention.
Venue: American journal of preventive medicine
Year: 2019

This study analyzed the associations among male adolescents' gender attitudes, intentions to intervene, witnessing peers' abusive behaviors, and multiple forms of adolescent violence perpetration. This community based evaluation aims to inform future youth violence prevention efforts through the identification of potential predictors of interpersonal violence perpetration.  Cross sectional data were from baseline surveys conducted with 866 male adolescents, aged 13 19 years, from community settings in 20 lower resource neighborhoods in Pittsburgh, PA (August 2015 June 2017) as part of a cluster RCT to evaluate a sexual violence prevention program. Participants completed in person, anonymous electronic surveys about gender attitudes, bystander intentions, witnessing peers' abusive behaviors, violence perpetration, and demographics. The analysis was conducted between 2018 and 2019.  The youth identified mostly as African American (70% or Hispanic, multiracial, or other (21% Most (88% were born in the U.S. and 85% were in school. Youth with more equitable gender attitudes had lower odds of self reported violence perpetration across multiple domains, including dating abuse (AOR=0.46, 95% CI=0.29, 0.72) and sexual harassment (AOR=0.50, 95% CI=0.37, 0.67) The relationship between intentions to intervene and violence perpetration was inconclusive. Witnessing peers engaged in abusive behaviors was associated with increased odds of multiple types of violence perpetration, such as dating abuse (witnessed 3 or more behaviors, AOR=2.41, 95% CI=1.31, 4.44)  This is the first U.S. based study to elicit information from male adolescents in community based settings (rather than schools or clinics) about multiple types of interpersonal violence perpetration. Findings support violence prevention strategies that challenge harmful gender and social norms while simultaneously increasing youths' skills in interrupting peers' disrespectful and harmful behaviors.
Adaptive inverse control of a temperature regulation system with feedforward
Venue: 2012 IEEE International Conference on Fuzzy Systems
Year: 2012

This paper presents an adaptive inverse control scheme in which adaptive signal processing techniques are used for system identification, dynamic compensation, and disturbance canceling. Unlike an approach proposed by Plett, no constraints are applied on the magnitude and distribution of the output signal of the disturbance canceller. Rather, the scheme allows feed forward control to compensate for known or measured disturbances. Experimental results of a temperature control system demonstrate effectiveness of the propose scheme.
Small and Medium Enterprises Across the Globe
Year: 2007

This paper analyzes the relationship between the relative size of the small and medium enterprise (SME) Sector and the business environment in 76 countries. The paper first describes a new and unique cross country database that presents consistent and comparable information on the contribution of the SME sector to total employment in manufacturing and GDP across different countries. We then relate the importance of SMEs and the informal economy to indicators of different dimensions of the business environment. We find that several dimensions of the business environment, such as lower costs of entry and better credit information sharing are associated with a larger size of the SME sector, while higher exit costs are associated with a larger informal economy.
Personalized digital marketing recommender engine
Year: 2020

E business leverages digital channels to scale its functions and services and operates by connecting and retaining customers using marketing initiatives. To increase the likelihood of a sale, the business must recommend additional items that the customers may be unaware of or may find appealing. Recommender Engine (RE) is considered to be the preferred solution in these cases for reasons that include delivering relevant items, hence improving cart value, and boosting customer engagement. The paper describes a model for delivering real time, personalised marketing information concerning the recommended items for online and offline customers, using a blend of selling strategies: up selling, cross selling, best in class selling, needs satisfaction selling and consultative selling. The model further defines the e marketplace by clustering items, customers and unique selling proposition (USP) and then gathering, storing, and processing transactional data, and displaying personalised marketing information to support the customer in their decision making process, even when purchasing from large item spaces. An experimental study using a quantitative research methodology was conducted in a mid size healthcare retailer, based out of India, to determine the tangible benefits. The model was tested with 100 online customers and, with the adoption of the proposed methodology, the results indicated growth in average monthly revenue (33.49% Average Order Value (AOV) (32.79% and Items per Order (IPO) (1.93%
Multi CNN Feature Fusion for Efficient EEG Classification
Venue: 2020 IEEE International Conference on Multimedia Expo Workshops (ICMEW)
Year: 2020

Recently, motor imagery (MI) signals have been used in BCI systems for disabled persons, controlling robots or wheelchairs or even driving cars. Hence, researchers are using machine learning and deep learning techniques for decoding MI signals. The properties of EEG signals like a low signal to noise ratio and its dynamic nature make it more complex and harder to decode. Research has shown that EEG has both spatial and temporal characteristics which can be exploited by deep learning models like convolution neural networks (CNN) This paper shows that the multilevel CNN model can extract dynamic correlations from EEG MI data. Multilevel CNN models are fused using autoencoder to extract the best features for EEG data which help improve MI decoding accuracy. The proposed fusion methods give a good performance for EEG decoding when tested for within subject trials as well as cross trials. The results are compared with state of the art techniques on public EEG dataset BCI competition IV 2a. Novel cross encoding technique is also proposed which helps us achieve big improvement in cross subject EEG decoding.
The effects of working memory training on improving fluid intelligence of children during early childhood
Year: 2017

Early childhood is a phase of rapid development in many aspects, and early interventions can be more effective than interventions provided later on. In prior research, working memory training has demonstrated the possibility to improve the fluid intelligence of both adults and school aged children. This study examined the training effects of enhancing the development of fluid intelligence in the long term for preschoolers. Seventy four preschoolers participated in the experiment. Participants in the experimental group were trained for 14 days using n back program. Fluid intelligence tests were administered four times: pretest, post test, 6 month follow up, and 12 month follow up. Results indicated that, the experimental group significantly enhanced their working memory performance. The experimental group also significantly outperformed the two control groups on the fluid intelligence post test and maintained their superior performance for up to 12 months. Implications are discussed within the context of providing effective early childhood interventions to improve fluid intelligence.
InFo: Indoor localization using Fusion of Visual Information from Static and Dynamic Cameras
Venue: 2019 International Conference on Indoor Positioning and Indoor Navigation (IPIN)
Year: 2019

Localization in an indoor or Global Positioning System (GPS) denied environment is paramount. It drives various applications that require locating humans or robots in an unknown environment. Various localization systems using different ubiquitous sensors such as camera, radio frequency, inertial measurement unit have been developed. Most of these systems cannot accommodate for scenarios which have substantial changes in the environment such as a large number of people (unpredictable) and sudden change in the environment floor plan (unstructured) In this paper, we propose a system, InFo that can leverage real time visual information captured by surveillance cameras and augment that with images captured by the smart device user to deliver accurate discretized location information. Through our experiments, we demonstrate that our deep learning based InFo system provides an improvement of 10% as compared to a system that does not utilize this real time information.
Fabrication of low resistance LaNixO3+d thin films for ferroelectric device electrodes
Year: 2018

LaNiO 3 thin films with different La/Ni ratios were deposited on Si substrates by sol gel process. The electrical resistivities of LaNi x O 3+ d films with different La/Ni ratios were measured by four probe method. LaNi 0.95 O 3+ d thin film has the lowest resistivity. First principle calculations show that LaNi 0.95 O 3+ d has the largest Ni O Ni bond angle and the shortest Ni O bond length, which means LaNi 0.95 O 3+ d has the strongest metallic property, hence, the electrical resistivity is the lowest. Au/PZT (PbZr 0.52 Ti 0.48 O 3 /LaNi x O 3+ d and Au/PZT/Pt ferroelectric capacitors were fabricated to evaluate LaNi x O 3+ d as a bottom electrode. It is shown that fatigue properties of PZT films can be significantly improved by using LaNi x O 3+ d instead of Pt as the bottom electrode. The I V test results of PZT films show that LaNi 0.95 O 3+ d as bottom electrode can reduce the threshold voltages of PZT films, suggesting that La/Ni ratio in LaNi x O 3+ d has a large influence on the film properties.
Family History of Premature Coronary Artery Disease (P CAD) A Non Modifiable Risk Factor? Dietary Patterns of Young Healthy Offspring of P CAD Patients: A Case Control Study (MAGNETIC Project)
Venue: Nutrients
Year: 2018

Dietary habits of healthy offspring with a positive family history of premature coronary artery disease (P CAD) have not been studied so far. The aim of this study was twofold: (1) to identify dietary patterns in a sample of young healthy adults with (cases) and without (controls) family history of P CAD, and (2) to study the association between dietary patterns and family history of P CAD. The data came from the MAGNETIC case control study. The participants were healthy adults aged 18 35 years old, with (n 351) and without a family history of P CAD (n 338) Dietary data were collected with food frequency questionnaire FFQ 6. Dietary patterns (DP) were derived using principal component analysis (PCA) The associations between the adherence to DPs and family history of P CAD were investigated using logistic regression. Two models were created: crude and adjusted for age, sex, smoking status, place of residence, financial situation, education, and physical activity at leisure time. Three DPs were identified: 'prudent' 'westernized traditional' and 'dairy, breakfast cereals, and treats' In both crude and adjusted models, subjects with family history of P CAD showed higher adherence by 31% and 25% to 'westernized traditional' DP (odds ratio (OR) 1.31, 95% confidence interval (95% CI) 1.12 1.53; p 0.005; per 1 unit of standard deviation (SD) of DP score and adjOR 1.25, 95% CI: 1.06 1.48; p 0.007; per 1 unit of SD of DP score, respectively) Young healthy adults with family history of P CAD present unfavorable dietary patterns and are potentially a target group for CAD primary prevention programs.

Venue: IEEE Access
Year: 2021

The importance of RFID technology is increasing as a means of enhancing productivity and efficiency, and reducing costs. The purpose of this research paper is to study the influence of technological, organizational, environmental, and innovation factors on the adoption of RFID technology by construction companies in Australia. With the growth of Australia's economy, in particular, the construction sector, the logistics departments in construction companies should pay attention to the adoption of more efficient technologies to provide better services for their customers. This paper provides a consolidated framework of RFID technology adoption based on studies on RFID technology adoption in particular from an IS perspective. The paper combines an integrated model of the Technology Organization Environment framework, the Diffusion of Innovation theory, and Actor Network Theory to establish a more comprehensive innovation adoption framework for RFID technology. The data gathered to study the factors affecting the adoption of RFID technology are analysed from the results of a survey of construction companies in Australia,  staff were participants in this research. The research results show that the factors which had a statistically significant and positive impact on the adoption of RFID services in construction companies were: relative advantage, compatibility, cost, expected benefits, top management support, external support and organization size. The findings from this research study have the potential to provide insights to firms seeking to make investment decisions on the adoption of RFID technology.
You've Been Pranked: Reality Tv, National Identity and the Privileged Status of Australian Children's Drama
Year: 2013

Australian children have always been considered a special television audience. In November 2009, Australia's public service broadcaster the ABC launched Australia's first dedicated free to air children's channel. Within a year of its launch, ABC3's most popular program was a local version of the transnational reality format,  The popularity of reality television with children challenges policy settings, including the Children's Television Standards (CTS) that privilege drama in the expression of the goals of cultural nationalism. While public service broadcasting ideology is expressed and applied to Australian commercial free to air channels through the CTS, public service media compete with pay TV channels for the child audience using a range of genres. Thus contemporary Australian children's television is characterised by an abundance of supply, pan platform delivery and a policy regime that has remained largely unchanged since the late 1970s.
How grass keeps growing: an integrated analysis of hormonal cross talk in the maize leaf growth zone
Venue: The New phytologist
Year: 2019

We studied the maize leaf to understand how long distance signals, auxin and cytokinin, control leaf growth dynamics. We constructed a mathematical model describing the transport of these hormones along the leaf growth zone and their interaction with the local gibberellin (GA) metabolism in the control of cell division. Assuming gradually declining auxin and cytokinin supply at the leaf base, the model generated spatio temporal hormone distribution and growth patterns that matched experimental data. At the cellular level, the model predicted a basal leaf growth due to cell division driven by auxin and cytokinin. Superimposed on this, GA synthesis regulated growth through the control of the size of the region of active cell division. The predicted hormone and cell length distributions closely matched experimental data. To correctly predict the leaf growth profiles and final organ size of lines with reduced or elevated GA production, the model required a signal proportional to the size of the emerged part of the leaf that inhibited the basal leaf growth driven by auxin and cytokinin. Excision and shading of the emerged part of the growing leaf allowed us to demonstrate that this signal exists and depends on the perception of light intensity.

When brands use CEOs and employees as spokespersons
Year: 2020

This paper aims to clarify the persuasion mechanism of chief executive officers (CEOs) and employees as endorsers of brand advertising and helps discern consumer attitudes toward internal endorsement.,The exploratory character of the present research required a qualitative approach combining focus groups and face to face interviews considered as both meaningful and complementary.,The findings suggest that while the celebrity endorsement ensures familiarity and likability, internal endorsement supports credibility and congruity with an important role of storytelling. Moreover, employee endorsements induce an internalization process based on the real self, while the endorser CEO induces admiration grounded in the ideal self. More fundamentally, the study reveals how the internal endorsement modifies the meaning transfer model and involves a process of meaning translation, which affects the corporate brand image rather than the product brand image.,The present paper reveals that CEOs and employees can be strong levers for gilding the corporate brand image compared to the celebrities who enhance the product brand image. Moreover, the authors show that the CEO is a character who can be admired without the threat of upward comparison at the opposite of celebrities. Finally, this research highlights the specific role of employees bringing authenticity because of their anchorage in real life.
