Deep Predictive Coding Neural Network for RF Anomaly Detection in Wireless Networks
Intrusion detection has become one of the most critical tasks in a wireless
network to prevent service outages that can take long to fix. The sheer variety
of anomalous events necessitates adopting cognitive anomaly detection methods
instead of the traditional signature-based detection techniques. This paper
proposes an anomaly detection methodology for wireless systems that is based on
monitoring and analyzing radio frequency (RF) spectrum activities. Our
detection technique leverages an existing solution for the video prediction
problem, and uses it on image sequences generated from monitoring the wireless
spectrum. The deep predictive coding network is trained with images
corresponding to the normal behavior of the system, and whenever there is an
anomaly, its detection is triggered by the deviation between the actual and
predicted behavior. For our analysis, we use the images generated from the
time-frequency spectrograms and spectral correlation functions of the received
RF signal. We test our technique on a dataset which contains anomalies such as
jamming, chirping of transmitters, spectrum hijacking, and node failure, and
evaluate its performance using standard classifier metrics: detection ratio,
and false alarm rate. Simulation results demonstrate that the proposed
methodology effectively detects many unforeseen anomalous events in real time.
We discuss the applications, which encompass industrial IoT, autonomous vehicle
control and mission-critical communications services.Comment: 7 pages, 7 figures, Communications Workshop ICC'1

OCEAN LITERACY OF PRIMARY STUDENTS OF INTERNATIONAL SCHOOLS IN RIYADH, SAUDI ARABIA
Background and Purpose: Recently, human impacts on marine ecosystems have intensified as the population and pressures increase. Human-originated pollutants of all kinds have impacted the oceans and the marine ecosystems. Oil spills, sewage, plastics, chemicals, garbage, carbon dioxide, and overfishing are the most challenging issues. It is known that school students are the future generation; they receive their information at school. Therefore, it is essential to assess students' knowledge and awareness regarding ocean related issues.
Methodology: This study investigated ocean literacy (OL) of primary school students at international schools in Riyadh, Saudi Arabia, based on the seven principles of ocean literacy. Resources from which children get information about the oceans was also investigated. Finally, the study investigated the attitudes of primary school students towards learning oceanography, protecting the oceans, and the relationship between humans and the environment. A questionnaire had been adapted from the Survey of Ocean Literacy and Experience (SOLE) and the Survey of Ocean Stewardship (SOS). The SOLE and SOS surveys had been developed originally by Greely (2008). However, due to the grade level of students and time issues, the number of questionnaire items were reduced and simplified. The questionnaire was distributed in two separate sessions. Students from three international schools, boys' sections, received the survey. 120 students answered the SOLE, and 102 students answered the SOS.
Findings: Results indicated a rather moderate level of ocean literacy of participants with a mean score of 12.56 (SD= 5.18) concerning the SOLE, and a mean score of 3.30 (SD= 1.12) concerning the SOS. As for the resource of information, results indicated the education program to be the students’ main source of education, television channels came second.
Contributions: Students of Riyadh international primary schools showed a positive attitude toward ocean stewardship. The study can help policy makers, curriculum developers and textbook authors to better understand the level of ocean literacy among students and take decisions to develop school curricula especially in the efforts to align with UN Decade of Ocean Science for Sustainable Development (2021-2030). It also corresponds to the 2020-2030 vision in Saudi Arabia.
Keywords: Ocean Literacy level, ocean Sciences materials, Saudi Arabia learners' attitudes

A Malaysian professional communication skills in English framework for English for occupational purposes courses
Malaysian employers have considerable reservations when it comes to graduates’ employability skills, particularly their flawed English language competence. Given the challenges faced by higher education institutions in Malaysia to match employers’ requirements, there is a need to initiate holistic and comprehensive research on the curriculum practices of current English for Occupational Purposes (EOP) courses. This study sought to better comprehend employers’ perspectives, expectations and practices in dealing with the English language demands of the workplace environment. The requirements demanded by Malaysian employers will determine the key definition of professional communication skills for successful workplace functions.
The aim of this study was twofold. Firstly, it intended to define Professional Communication Skills (PCS) by looking at the needs and requirements of Malaysian stakeholders, namely employers, the government and academia. This component explores the requirements, suggestions as well as common practices in relation to English language communication carried out at the workplace in the public and private sectors in Malaysia as voiced by the stakeholders. These valuable facts will help to fulfil the fundamental objective of this study, which is to determine the key definition of professional communication skills identified by Malaysian stakeholders for successful workplace functions. A clearly defined Professional Communication Skills Framework in English is aimed for at the end of this study. Secondly, it also aims to produce an informed, impartial and highly valid PCS framework for English by having the stakeholders thoroughly involved in creating meaning and amending the components within the framework during the validation stage of the study. Additionally, in order to make sure that the framework is not only valid but also achievable, a few experts in the field of teaching English in higher education have looked through the framework thoroughly.
This qualitative study sits within the interpretivist paradigm, where data were primarily drawn from in-depth interviews with 24 respondents in the following subgroups: 1) human resource managers from key multi-national industries (10 respondents); 2) government executives who recruit entry-level employees for public sector (4 respondents) and; 3) EOP instructors and HE liaison officers for industrial training (10 respondents). The data were subjected to rigorous deductive and iterative analysis in which soft systems methodology (SSM) was applied. To assure the rigour, integrity and legitimacy of the research process and its worth, trustworthiness criteria were applied all the way through the study.
Key findings of the study centre on the complexities of graduates’ English language workplace literacies, where it was discovered that the balance of breadth and depth of communicative competence should be embedded throughout the system of education, as early as in pre-primary education. Contrary to expectations, the findings illustrate that graduates’ personal attributes were rated more important than communicating fluently in the English language. Stakeholders compellingly proposed that these attributes should be stressed during the teaching and learning process in HE institutions and observable measures should be designed to assess the graduates’ personal attributes that are desired by stakeholders. The findings also stress the dire need to put emphasis on fluency over accuracy in the HE curriculum.
This study has yielded findings that make an original contribution to both the theory and practice of English language literacies since it adds to the broader view of workplace literacies by unveiling the requirements for English language used in a professional setting situated in a Malaysian context. This study has provided conclusive evidence by documenting Malaysian stakeholders’ requirements regarding the workplace literacies of graduates, scrutinising the findings and developing a practical PCS framework for English, using a Communication Competence Model (Morealle, Spitzberg and Barge, 2007) as its point of departure. These outcomes are especially beneficial for informing policy makers’ agendas in producing competent graduates for the future local and global workforce

Brain drain of Malaysian talent to Singapore
Globalization has inadvertently brought about the global war for talent.The competition for talent is not merely confined to companies but has extended to countries.Countries with the best talents are the ones most likely to attract foreign investments.As foreign companies and entrepreneurs mull over which Asian country to base their business operations in, the availability of a productive, cost-effective, and
efficient workforce definitely plays in favor of a given business jurisdiction.This article was motivated by the increasing number of Malaysian professionals fleeing the home country to serve in foreign lands.With the Prime Minister’s agenda of trying to achieve the high income nation status before 2020 at hand, this has been a critical issue and warrants immediate attention.This article addresses the need of these experts here in the home country to improve the nation’s economy. While the country is losing high skilled labor, it is only able to attract low skilled labor.Also the main concern is that Malaysia is losing its most talented citizens to its closest neighbor such as Singapore, Australia and also to the USA, UK, Hong Kong just to name a few. This article looks at factors that have led to the Brain Drain phenomenon and intends to put forward efforts in order to overcome this predicament
