A relatively new approach to address the teaching of the target culture in Algerian middle school:the fifth use of ICTs in language learning
Year: 2016

Both language teachers and applied linguists are becoming aware of the importance of addressing the culture of a community while teaching the language of its speakers  In Algeria, in the case of English as a Foreign Language (EFL) in middle and secondary schools, the four language skills: reading, writing, listening, and speaking are the first concern of both teachers and educators. Teaching the foreign culture; however, is rarely taken into account when planning and designing curricula and textbooks for instance. One of the reasons behind this is that it is not yet clear how to teach culture, at what stage of learning the language it should be added and how to make young learners aware of the differences between their own culture and that of the target language. My research investigates the possibility of using educational technologies, specifically Information and Communication Technologies (ICTs) to raise cultural and intercultural awareness amongst Algerian middle school learners of English. It aims first at checking the current situation of the target culture in textbooks of English at the level of middle schools; second, identifying the factors affecting the use of ICTs in teaching and learning EFL. Last and most importantly, it aims at finding out how ICTs could be used in teaching the target culture rather than restricting their use to develop the language skills only. I will be using qualitative methods in collecting my data, I will first conduct a textual analysis of the two middle school textbooks of English, the old one and the new one. Then, I will use interviews with both Algerian EFL middle school teachers and inspectors of English of the same level. I will also try to get access to textbook designers and interview them, and take some field notes during teachers training courses. Based on the analysis and discussions of my data, I intend to formulate suggestions and recommendations concerning both future use of ICTs in EFL learning and the status of culture in the process of teaching and learning EFL in Algeria.
Does doing good lead to doing better in emerging markets? Stock market responses to the SRI index announcements in Brazil, China, and South Africa
Venue: Journal of the Academy of Marketing Science
Year: 2019

This paper investigates whether and how emerging markets reward firms' corporate social responsibility (CSR) performance. We focus on the socially responsible investment (SRI) index, which lists the top CSR performers and serves as a tool to help investors make investment decisions based on financial and social criteria. We empirically test the financial market responses to the announcements of pioneering SRI indices recently launched in Brazil, China, and South Africa. We find that inclusion on an SRI index in these markets is associated with positive abnormal returns. However, inclusion on an SRI index does not benefit all firms equally: the positive financial response is strengthened by R&D expenditures but weakened by advertising expenditures; it is stronger for firms that have expanded globally to developing countries than those to developed countries.

The Effects of Message Framing and Source Credibility on Green Messages in Hotels
Year: 2014

This study used an experimental approach to examine the influence of message framing and source credibility on potential hotel customers' attitudes, behavioral intentions, attention, and environmentally friendly activities (EFAs) toward messages about protecting the environment. With 386 participants, this study employed a 2 x 2 between subject design comparing a positive message frame, a negative message frame, a credible source, and a noncredible source. The results reveal that messages from a credible source that are positively framed led to the most positive attitudes toward the messages themselves, visit intention, and EFAs. Even without regard to source credibility, positively framed messages were more effective than those with a negative frame. The implication for hospitality practitioners is to maintain a positive frame for messages that encourage guests to participate in a hotel's sustainability programs, and to add a credible source for additional message strength.
Who Is Bowling Alone? Quantile Treatment Effects of Unemployment on Social Participation
Year: 2020

This article examines heterogeneity in the effect of unemployment on social participation. Whereas existing studies on this relationship essentially estimate mean effects, we use quantile regression methods to provide a broader and more complete picture. To ac count for the potential endogeneity of job loss, we estimate quantile treatment effects (on the treated) based on entropy balancing and focus on unemployment due to plant closures. Using German panel data, we show that the effect of unemployment varies across the distribution of public social activities. It is large and negative for individuals in the middle and lower part of the distribution of public activities, whereas those participating a lot are not affected. By contrast, the effect of unemployment on private social participation is virtually zero for individuals at the lower part of the outcome distribution and weakly positive in the middle. Our findings suggest that active labor market policies should account for target group specific elements, tailored to those individuals which are most adversely affected by unemployment.
A procedure for semi automated cadastral boundary feature extraction from high resolution satellite imagery
Year: 2018

Fit for purpose land administration aims to align cadastral policies, administration and technology selection with the prevailing societal needs and capacity within a country context. It seeks to support delivery of more rapid and low cost cadastral boundary mapping and ultimately more widespread land tenure security. The philosophy suggests that when high positional accuracies are not the primary concern, but when time pressure is, high resolution satellite images can serve as a source for creating cadastral boundary information. This paper explores the potential of mean shift segmentation plug in in QGIS to semi automatically extract cadastral boundaries in rural areas based on the land cover information from WorldView 2 satellite images. The segmentation gives a vector file satisfying many cadastral boundary requirements and ready to be used in a GIS environment. The buffer overlay method was used to assess the quality of extracted boundaries. For a non vegetated terrain having visible boundaries, the approach could be taken as an alternative to support existing, relatively slow, boundary mapping approaches by minimizing the effects of manual digitization and surveying.
Heterogeneous Cellular Network With Energy Harvesting Based D2D Communication
Venue: IEEE Transactions on Wireless Communications
Year: 2016

The concept of mobile user equipment (UE) relay (UER) has been introduced to support device to device (D2D) communications for enhancing communication reliability. However, as the UER needs to use its own power for other UE's data transmission, relaying information in D2D communication may be undesirable for the UER. To overcome this issue, motivated by the recent advances in energy harvesting (EH) techniques, we propose a D2D communication provided EH heterogeneous cellular network (D2D EHHN) where UERs harvest energy from an access point (AP) and use the harvested energy for D2D communication. We develop a framework for the design and analysis of D2D EHHN by introducing the EH region (EHR) and modeling the status of harvested energy using Markov chain. The UER distribution is derived, and a transmission mode selection scheme including the efficient UER selection method is proposed. The network outage probability is derived in close form to measure the performance of D2D EHHN. Based on our analysis results, we explore the effects of network parameters on the outage probability and the optimal offloading bias in terms of the outage probability. Particularly, we show that having a high EH efficiency enhances the performance of D2D EHHN, but can also degrade, especially for dense network.
Rethinking the Role of Invited Inferencing in Change from the Perspective of Interactional Texts
Year: 2018

The hypothesis that "invited inferences" are factors in change and challenges to it are reviewed. In light of recent work on historical construction grammar and interactional discourse analysis, I suggest that at least three types of inferences play a role in interactional contexts: local inferences associated with specific expressions; discourse structuring inferences pertaining to factors like coherence, backgrounding and foregrounding; and turn taking inferences associated with turn relevant positions. A case study tests this suggestion: the development of discourse structuring uses of a family of Look expressions. Turn taking has been regarded as a trigger in related changes. However, in this case not turn taking, but rather a profile shift associated with non use of complementizers is hypothesized to be a crucial enabling factor.
Multi train trajectory optimization for energy efficient timetabling
Venue: Eur. J. Oper. Res.
Year: 2019

This paper proposes a novel approach for energy efficient timetabling by adjusting the running time allocation of given timetables using train trajectory optimization. The approach first converts the arrival and departure times to time window constraints in order to relax the given timetable. Then a train trajectory optimization method is developed to find optimal arrival/departure times and optimal energy efficient speed profiles within the relaxed time windows. The proposed train trajectory optimization method includes two types, a single train trajectory optimization (STTO) which focuses on optimizing individual train movements within the relaxed arrival and departure time windows, and a multi train trajectory optimization (MTTO) which computes multi train trajectories simultaneously with a shared objective of minimizing multi train energy consumption and an additional target of eliminating conflicts between trains. The STTO and MTTO are re formulated as a multiple phase optimal control problem, which has the advantage of accurately incorporating varying gradients, curves and speed limits and different train routes. The multiple phase optimal control problem is then solved by a pseudospectral method. The proposed approach is applied in case studies to fine tune two timetables, for a single track railway corridor and a double track corridor of the Dutch railway. The results suggest that the proposed approach is able to improve the energy efficiency of a timetable.
Real Time Multi Material Reflectance Reconstruction for Large Scale Scenes Under Uncontrolled Illumination from RGB D Image Sequences
Venue: 2019 International Conference on 3D Vision (3DV)
Year: 2019

Real time reflectance reconstruction under uncontrolled illumination conditions is well known to be a challenging task due to the complex interplay of scene geometry, surface reflectance and illumination. Nonetheless, recent works succeed in recovering both unknown reflectance and illumination in an uncontrolled setting. However, they are either limited regarding the scene complexity (single objects homogeneous materials) or are not suitable for real time applications. Our proposed method enables the recovery of heterogeneous surface reflectance (multiple objects and spatially varying materials) in complex scenes at real time frame rates. We achieve this goal in the following way: First, we perform a 3D scene reconstruction from an input RGB D stream in real time. We then use a deep learning based method to estimate Ward BRDF parameters from observations gathered from individual segmented scene objects. Subsequently we refine these reflectance parameters to allow for spatial variations across the object surfaces. We evaluate our method on synthetic scenes and successfully apply it to real world data.
r UNet: Leaf Position Reconstruction in Upstream Radiotherapy Verification
Venue: IEEE Transactions on Radiation and Plasma Medical Sciences
Year: 2021

Monolithic active pixel sensor (MAPS) devices are an effective tool for upstream verification of intensity modulated radiotherapy (IMRT) treatments. It is crucial to measure with high precision the positions of the multi leaf collimators (MLCs) used to shape the beam in real time, in order to enhance the quality and safety of treatments. This article describes r UNet, a deep learning based solution for leaf position reconstruction. The model is used to analyze the high resolution images produced by a Lassena MAPS device in order to automatically determine the leaf positions. Image segmentation and leaf position estimation are performed simultaneously in a multitask setting. r UNet obtained an average Dice coefficient of 0.96 0.03 for the reconstructed image masks in the held out test set; whilst the mean squared error (MSE) resulting from the estimation of the MLC positions is 0.003 mm, with a resolution ranging between 45 and 53 <inline formula> <tex math notation="LaTeX"\mu \text{m} /tex math>/inline formula> for leaf extensions between 1 and 35 mm. On unseen leaf positions, r UNet yielded a single leaf resolution between 54 and 88 <inline formula> <tex math notation="LaTeX"\mu \text{m} /tex math>/inline formula> depending on the leaf extension, and an average MSE of 0.07 mm. These results were obtained using single frames of data collected at 34 frames/s.
Why Do Short Selling Bans Increase Adverse Selection and Decrease Price Efficiency?
Year: 2020

When short selling is costly, owners of an asset have greater incentive to become informed than nonowners because trading on negative information is easier for them. Thus, information acquisition concentrates among investors owning the asset. A short selling ban restricts selling to only the relatively more informed investors who own the asset, increasing adverse selection but only on the sell side of the market. Price efficiency declines due to less overall information acquisition because a ban magnifies the disincentive to gather information for investors not owning the asset. Evidence from the 2008 U.S. short selling ban is consistent with these theoretical predictions.
Dendritic Cells and Programmed Death 1 Blockade: A Joint Venture to Combat Cancer
Venue: Front. Immunol.
Year: 2018

Two decades of clinical cancer research with dendritic cell (DC) based vaccination have proved that this type of personalized medicine is safe and has the capacity to improve survival, but monotherapy is unlikely to cure the cancer. Designed to empower the patient's antitumor immunity, huge research efforts are set to improve the efficacy of next generation DC vaccines and to find synergistic combinations with existing cancer therapies. Immune checkpoint approaches, aiming to breach immune suppression and evasion to reinforce antitumor immunity, have been a revelation in the immunotherapy field. Early success of therapeutic antibodies blocking the programmed death 1 (PD 1) pathway has sparked the development of novel inhibitors and combination therapies. Hence, merging immunoregulatory tumor specific DC strategies with PD 1 targeted approaches is a promising path to explore. In this review, we focus on the role of PD 1 signaling in DC mediated antitumor immunity. In the quest of exploiting the full potential of DC therapy, different strategies to leverage DC immunopotency by impeding PD 1 mediated immune regulation are discussed, including the most advanced research on targeted therapeutic antibodies, lessons learned from chemotherapy induced immune activation, and more recent developments with soluble molecules and gene silencing techniques. An overview of DC/PD 1 immunotherapy combinations that are currently under preclinical and clinical investigation substantiates the clinical potential of such combination strategies.
Solitary Rectal Ulcer Syndrome in a 12 Year Bangladeshi Boy: an Unusual Cause of Rectal Bleeding
Year: 2020

Solitary rectal ulcer syndrome (SURS) is an benign, rare, rectal disorder in children. In 1829, Cruveilhier described four unusual cases of rectal ulcers. The term "solitary ulcers of the rectum" was used by Lloyd Davis in the late 1930s. The term solitary rectal ulcer syndrome is a misnomer because i) ulcers are found in 40% of patient, others having single or multiple ulcers including hyperemic mucosa to broad based polypoid or mass lesions ii) 20% of patients have a solitary ulcer, other lesions are different in shape and size and iii) may involve the sigmoid colon. Regarding pediatric age group, there are very limited data. From adult study, SRUS is an infrequent, with an estimatedprevalence ofabout 1 in 100000 persons per year. The pathogenesis is incompletely understood. Various factors may be involved in its disease process. Most accepted theories are factors associated with direct trauma or causes of local ischemia. Case Report XX, a 12 year old immunized boy, 5th issue of nonconsanguineous parents, presented with painless fresh per rectal bleeding for last 3 years. Bleeding occur drop by drop after defecation or occasionally mixed with stool with variable amount. He also mentioned about something coming out per rectum for last 1 year  He had no history of abdominal pain, fever, tenesmus, constipation, manual disimpaction of stool, diarrhea, joint pain, bleeding manifestation from other site, contact with tuberculosis patient or family history of colonic polyp. But he had history of feeling of incomplete defecation and prolonged straining during defecation. With these complaints he visited to several physicians and underwent colonoscopy for 3 times. Colonoscopy findings was, mucosa of rectum and sigmoid colon looked granular, loss of vascular pattern, covered with whitish mucous like substances, friable and was diagnosed as a case of ulcerative colitis.  Solitary rectal ulcer syndrome (SRUS) is an uncommon cause of per rectal bleeding in children. Due to it's wide variety of presentation and rarity, it is frequently misdiagnosed as other clinical condition like inflammatory bowel disease, rectal polyp, amoebiasis or malignancy. Here we presenting a case initially misdiagnosed as ulcerative colitis, latter after thorough evaluation diagnosed as a case of SRUS.
Digital Copyright Protection Scheme Based on JUNA Lightweight Digital Signatures
Venue: 2012 Eighth International Conference on Computational Intelligence and Security
Year: 2012

With the swift development of computer network and digitalization technology, researches on the digital copyright protection becomes specially important. Images, texts, and common signatures are used as invisible watermarks in traditional digital copyright protection systems, which will lead to a complicated embedding process. In this paper, JUNA(Joint Unit for Numbering Algorithm) Lightweight Digital Signature is acted as a visible watermark and stacked on the lower right corner of the original work in a dominant way. So we needn't to consider the selection of embedded position. The scheme can simplify the process of the digital copyright protection, meanwhile, ensure the security of the system. The length of the signature is only 80 bits. After the signature is coded by 32 bit system, the length of which is only 16 characters. That means, in the digital copyright protection system, it can implement the requirement of lower space consumption, lower time consumption and lower cost. With the combination of cloud computing concept, the author proposes a digital copyright protection scheme based on JUNA Lightweight Digital Signature, builds a digital copyright protection model, and analyzes the performance of the scheme.
Pan Turkism and Discussion on Muslim National School in the Middle Volga Region After 1905
Year: 2015

This article examinesthe situation in the Muslim school (madrasah) in the Middle Volga region after 1905 and changing aspirations of Russians towards the acculturation of Muslims connected with it. The fears and suspicions of the Russian authorities concerned the development of cultural ties between Russian and Turkish Muslims, which legitimized the idea that these ethnic groups could unite in a new political entity on the basis of common religion or on a common ethno linguistic basis (Turkish) Much of the blame for the spread of Pan Turkic and Pan Islamic ideas was placed upon the new method schools of the region. Muslim traditional educational system also underwent changes which particularly involved teaching of the Russian language and other secular subjects.While Muslim community continued to reform their educational system, the local authorities continued to question the idea of the Muslim "
Outcome of a one month therapy intensive for chronic aphasia: variable individual responses.
Venue: Seminars in speech and language
Year: 2010

We examined the outcome of a 1 month intensive treatment block for people with chronic aphasia. The selected participants were eight chronically impaired people (mean months post onset [MPO] 34) We conducted pre and post treatment assessments using the English language version of the Aachen Aphasia Test (EAAT) and the Communicative Effectiveness Index (CETI) The group had significant overall improvement following treatment, which was maintained for 1 month, most significant changes seen on the EAAT were mainly in naming, comprehension, and reading and writing. Improvement was also observed on the CETI. Individual responses to treatment were variable, with some participants making more progress than others. Although the more mildly aphasic participant made most gains overall, the most severe and oldest participant made the most gains. We observed significant improvement in some subtests for some participants 1 month after treatment had ceased, suggesting a delayed effect of treatment. We conclude that short term blocks of intensive treatment for chronically aphasic individuals can be effective.
