A Study of Android Malware Detection Techniques and Machine Learning
Venue: MAICS

Android OS is one of the widely used mobile Operating Systems. The number of malicious applications and adwares are increasing constantly on par with the number of mobile devices. A great number of commercial signature based tools are available on the market which prevent to an extent the penetration and distribution of malicious applications. Numerous researches have been conducted which claims that traditional signature based detection system work well up to certain level and malware authors use numerous techniques to evade these tools. So given this state of affairs, there is an increasing need for an alternative, really tough malware detection system to complement and rectify the signature based system. Recent substantial research focused on machine learning algorithms that analyze features from malicious application and use those features to classify and detect unknown malicious applications. This study summarizes the evolution of malware detection techniques based on machine learning algorithms focused on the Android OS.
A study of android malware detection techniques in virtual environment
Venue: Cluster Computing

With the rapid development of mobile environment, cyber attacks have become more commonplace and more sophisticated. In smartphone operating system market, in particular, Android platform accounts for a large portion (65 or higher) At the same time, malwares on the Android platform, has increased exponentially. This, such as mobile Internet service provider (ISP) operator and device manufacturers, have applied an anti virus product. However, there exhibit a high false positive rate to detect malwares because these are based on patterns or heuristic. To solve this problem, this study proposed and implemented Android malware detection techniques in virtual environment, using single physical machine. The proposed system is divided into a host system and virtual environment. The former features black market crawler designed to collect malware, hypervisor targeted for the communication and control of virtual machine and host machine and main module which transmits analysis file and result log to each system. In virtual environment, agent and emulator were implemented to analyze malware suspicious application. This study implemented more active and faster Android malware detection techniques through black market crawling and Linux kernel hooking mechanism.

The study aims to provide useful guidance for future investigations in computational algorithms
Bridging Islamic Financial Literacy and Halal Literacy: The Way Forward in Halal Ecosystem

Halal business is not just about halal ingredients and production. Besides focusing on halal production, the right Halal business operators should also concentrate in adopting Halal financing that is called Islamic financing. However, the assessment of the level of awareness, knowledge and skills of Halal and Islamic financing among business operators should be prepared. This paper aims to bridge the Halal Literacy and Islamic Financial Literacy on the attitude of Halal business producers towards Islamic financing adoption. This study proposes the measurement and validity approach for Halal Literacy and Islamic Financial Literacy. Halal Literacy and Islamic Financial Literacy are two crucial concepts where it can lead to the behavior of person towards its decisions especially in adopting Islamic financing. Halal Literacy and Islamic Financial Literacy will be measured using true/false test questions with an option to choose don't know. Then, Confirmatory Factor Analysis (CFA) will be used to analyze the scoring using Weighted Least Square method to test the construct validity. This study is attempted to contribute towards new theoretical knowledge especially in proposing the measurement items for Halal Literacy and Islamic Financial Literacy. This study also expected to help the policymaker to understand the level of literacy among consumers, especially from Halal business producer's perspective.
Giant Benign Mediastinal Masses Extending into the Pleural Cavity.
Venue: Surgery journal

The aim of the study was to evaluate the results of surgery to remove huge mediastinal masses and their pathology. Surgical resection was chosen for accurate diagnosis and treatment of the huge mediastinal masses extending into the pleural cavity.  Records were reviewed for eight patients who had the diagnosis of huge benign mediastinal masses and who underwent operation; details of the patients and operations were recorded.  Mean age was 34.5 (range 22 to 44) years, and male to female ratio was 2:6. Computed tomography and magnetic resonance imaging (MRI) were used to evaluate the location and extent of the abnormality and to characterize the tissue components of the mass. Most of the tumors were located in the posterior mediastinum. The most frequent presenting symptom was exertional dyspnea. The majority of cases underwent posterolateral thoracotomy, and complete resection was possible in seven patients. Partial resection could only be performed in one. The mean diameter of the resected masses was 15 x 10 cm. Histopathologic examination revealed 3 neurogenic tumors, 2 teratomas, 1 thymolipoma, and 1 ectopic thyroid, and 1 hemangioma. Minor complication was seen in two cases.  The presurgical thoracic MRI provided correct diagnosis along with radiologic characterization and topography. Surgery must be the preferred treatment in huge benign mediastinal masses.

A participatory approach to the development of a co produced and co delivered information programme for users of services and family members: the EOLAS programme (paper 1)
Venue: Irish Journal of Psychological Medicine

The EOLAS programme is a peer and clinician led mental health information programme on recovery from mental health difficulties, specifically for people with a diagnosis of schizophrenia spectrum or bipolar disorders, their family members and significant others.  This article, the first of a two part series, outlines the background to and the rationale behind the EOLAS programme, and traces the participatory process used to inform the development and implementation of the pilot phase of the project. The aims of the programme, and the overarching principles that guided its development, delivery and evaluation, including the set up of the project steering group are outlined and discussed.  Two separate programmes, one for family members and one for service users were designed. In addition, participant and facilitator handbooks were developed for each programme, including a training programme for facilitators.  Central to a recovery oriented service is the involvement of service users and families in the design and delivery of services. EOLAS is one potential model for achieving this aim.
Developing an Experiential Definition of Recovery: Participatory Research With Recovering Substance Abusers From Multiple Pathways
Venue: Substance use misuse

The What is Recovery? (WIR) study identified specific elements of a recovery definition that people in substance abuse recovery from multiple pathways would endorse.  To explain how participatory research contributed to the development of a comprehensive pool of items defining recovery; and to identify the commonality between the specific items endorsed by participants as defining recovery and the abstract components of recovery found in four important broad recovery definitions.  A four step, mixed methods, iterative process was used to develop and pretest items (August 2010 to February 2012) Online survey recruitment (n 238) was done via email lists of individuals in recovery and electronic advertisements; 54 were selected for in depth telephone interviews. Analyses using experientially based and survey research criteria resulted in a revised item pool of 47 refined and specific items. The WIR items were matched with the components of four important definitions.  Recovering participants (1) proposed and validated new items; (2) developed an alternative response category to the Likert; (3) suggested criteria for eliminating items irrelevant to recovery. The matching of WIR items with the components of important abstract definitions revealed extensive commonality.  The WIR items define recovery as ways of being, as a growth and learning process involving internal values and self awareness with moral dimensions. This is the first wide scale research identifying specific items defining recovery, which can be used to guide service provision in Recovery Oriented Systems of Care.
Routing optimization for server centric data center networks
Venue: Comput. Sci. Inf. Syst.

Server centric data center architecture has been proposed to provide high throughput, scalable construction and error tolerance with commodity servers and switches for cloud data centers. To fully utilize those advantages of servercentric data center, an effective routing algorithm to find high quality multiple paths in Server centric network is needed. However, current routing algorithms cannot achieve this completely: 1) the state of art routing algorithms in server centric data center just consider hop count when selecting paths; 2) traditional multi constraint QoS routing algorithms only find one feasible path and are usually switch oriented; 3) present multi path algorithms cannot guarantee the performance of the founded paths. In this paper, we propose a multi constrained routing algorithm for servercentric data centers, named Server Centric Multi Constrained Routing Algorithm (SCRAT) This algorithm exploits the topology features of the Server Centric data center to decrease the algorithm complexity and returns optimal and feasible paths simultaneously. In simulations, SCRAT has a very high probability (more than 96% to find the exact optimal path, and the cost of the optimal path found in SCRAT is about 10% less compared with path found in previous TS MCOP. Compared with previous MPTCP, SCRAT reduces the path delay by 18% less and increase the bandwidth by 20%
Students' Preferences on the Use of Mother Tongue in English as a Foreign Language Classrooms: Is It the Time to Re Examine English Only Policies?

In literature on bilingual teaching, different perspecttives exist for and against the use of first language (L1) in English as a Foreign Language (EFL) classrooms. There is a continuing matter of debate on whether L1 contributes to or precludes the learning of a second language (L2) Numerous studies have been conducted on this topic, but no clear consensus exists on whether L1 should be banned or its inclusion in EFL classrooms should be allowed. A significant body of literature has explored this phenomenon from teachers' perspectives, and an adequate number of studies have explored the phenomenon from the students' perspectives. However, few studies have identified the reasons for which students need such an inclusion. More importantly, no studies seem to have considered demographic variables that may directly influence students' perceptions of the use of L1 in their (L2) classrooms, that is; educational background and their language proficiency level. This study primarily investigated whether students' educational background and their L2 proficiency influenced their perceptions of the use of Turkish in their L2 classrooms as well as their perceptions and needs for the use of L1 in their classrooms. The study was conducted on a sample of 303 Turkish learners of EFL at English Preparatory School of European University of Lefke in Northern Cyprus. Data were collected using a questionnaire. Analysis of the data indicated that EFL students had high positive perceptions toward the inclusion of L1 in their L2 classes and that their perceptions were affected by their demographic characteristics. Students with lower level of L2 proficiency were also found to have more positive perceptions toward the use of L1. Furthermore, the particular issues where students needed L1 were also identified. Implications for language teachers and policy makers are discussed.
The Gender Wage Gap: Extent, Trends, and Explanations

Using PSID microdata over the 1980 2010, we provide new empirical evidence on the extent of and trends in the gender wage gap, which declined considerably over this period. By 2010, conventional human capital variables taken together explained little of the gender wage gap, while gender differences in occupation and industry continued to be important. Moreover, the gender pay gap declined much more slowly at the top of the wage distribution that at the middle or the bottom and by 2010 was noticeably higher at the top. We then survey the literature to identify what has been learned about the explanations for the gap. We conclude that many of the traditional explanations continue to have salience. Although human capital factors are now relatively unimportant in the aggregate, women's work force interruptions and shorter hours remain significant in high skilled occupations, possibly due to compensating differentials. Gender differences in occupations and industries, as well as differences in gender roles and the gender division of labor remain important, and research based on experimental evidence strongly suggests that discrimination cannot be discounted. Psychological attributes or noncognitive skills comprise one of the newer explanations for gender differences in outcomes. Our effort to assess the quantitative evidence on the importance of these factors suggests that they account for a small to moderate portion of the gender pay gap, considerably smaller than say occupation and industry effects, though they appear to modestly contribute to these differences.
A novel research methodology for supply network collaboration management
Venue: Inf. Sci.

A supply chain has a multi stage complex topological structure that is reconfigured dynamically and evolves over time. These features represent great challenges to supply network collaboration management. This paper proposes a novel research methodology for supply network collaboration research, including a methodological basis, a procedure model, and a conceptual decision making model. The methodology integrates a three dimensional flow model with a SCOR (Supply chain operations reference model) based process modeling approach, a multi agent system, distributed simulation technology and a three dimensional decision making model to support supply network analysis, modeling, standardization, development, implementation and decision making. This method creatively uses material, information and time flows as the research objects, combines process oriented and agent oriented modeling approaches and integrates multiple models, approaches and technologies to reduce research assumptions and constraints while improving the quality of research findings. The case for a five stage make to order (MTO) supply network is studied for the application of the methodology and to verify its effectiveness.
Stuck song syndrome: musical obsessions when to look for OCD.
Venue: The British journal of general practice the journal of the Royal College of General Practitioners

Earworms or musical obsessions (also known as stuck song syndrome [SSS] are common in the general population, but can be more pronounced and debilitating in patients with obsessive compulsive disorder (OCD) Recurring tunes that involuntarily pop up and stick in your mind are common: up to 98% of the Western population has experienced these earworms.1 Usually, stuck songs are catchy tunes, popping up spontaneously or triggered by emotions, associations, or by hearing the melody.1 Aetiologically, earworms are related to memory: auditory information functions as a strong mnemonic. Psychologically, earworms are a 'cognitive itch' the brain automatically itches back, resulting in a vicious loop. The more one tries to suppress the songs, the more their impetus increases, a mental process known as ironic process  Those most at risk for SSS are: females, youth, and patients with OCD.1 Patients with OCD (lifetime prevalence >1% typically suffer
Identification of Faults in Power System Using Fuzzy Logic Technique

Power reliability and quality of electrical power supply is mostly affected by occurrence of faults in transmission/distribution network. To reduce the time of power outages and for the immediate restoration, the fault identification method must be very effective. Under faulty condition system operator receives very complex information difficult to make decision on restoring a tripped feeder to normal operation. Hence, to build the decision making ability effectively, fuzzy logic based fault diagnosis method is presented in this paper. This method can classify and identify the ten types of shunt faults that occur to Radial topology of transmission/distribution network. This method uses three phase feeder current, neutral current and phase voltages as input to the fuzzy inference system (FIS)
Towards a Complete View of the Certificate Ecosystem
Venue: Internet Measurement Conference

The HTTPS certificate ecosystem has been of great interest to the measurement and security communities. Without any ground truth, researchers have attempted to study this PKI from a variety of fragmented perspectives, including passively monitored networks, scans of the popular domains or the IPv4 address space, search engines such as Censys, and Certificate Transparency (CT) logs. In this work, we comparatively analyze all these perspectives. We find that aggregated CT logs and Censys snapshots have many properties that complement each other, and that together they encompass over 99% of all certificates found by any of these techniques. However, they still miss 1.5% of certificates observed in a crawl of all domains in .com, .net, and .org. We go on to illustrate how this combined perspective affects results from previous studies. In light of these findings, we have worked with the operators of Censys to incorporate CT log data into its results going forward, and we recommend that future HTTPS measurement adopt this new vantage.
Teacher Factors That Influence Secondary School Student Participation in Lodwar, Turkana County, Kenya

The pivotal role played by education to growth and development of an individual cannot be underestimated. In spite of this, some regions in Kenya, Turkana County included, still experience low level of participation in education. Many factors have been attributed to this phenomenon. However, few studies have addressed the teacher factors influencing the level of participation of secondary school students in school. The study therefore focused on establishing this using descriptive survey design. Simple random sampling was used to select a sample size of 200 students from 8 schools in Lodwar, Turkana County. The study established that teacher qualification, personal characteristics and their role in motivating learners to work hard enhance student performance and shape their decisions about the future. However, there was neither gender nor grade level difference in students determining teacher factors contributing to level of participation. The study recommends that the government should encourage the training of teachers to incorporate not only skills related to pedagogy, but also other skills that necessitate them to work effectively and efficiently.
Challenges Facing Mobile Schools among Nomadic Pastoralists: A Case Study of Turkana County, Kenya

As the universalization of primary education has become a central factor in countries' global competitiveness, nations round the world are engaging in alternative approaches for educational provision initiatives aimed at reaching the disadvantaged nomadic pastoralist groups. Among the strategies in use are mobile schools, as a Non Formal Education (NFE) approach. Mobile schools are weighed down with challenges of implementation and its graduates being integrated into the formal system of education, hence threatening its survival. This study presents the findings of a qualitative multiple case study conducted on mobile schools aimed at exploring the challenges facing provision of education to the nomadic pastoralists of Turkana County, Kenya. This study used bottom up policy implementation theoretical approach. The findings of this study indicate that inadequate number of teachers; lack of teacher motivation; lack of community awareness and sensitization on importance of schooling; lack of food and water for both human and livestock; and unavailability of health services as the key challenges. The study recommends more teachers to be employed, teachers motivation be improved and a multifaceted approach in education provision in order to promote the sustainability of this form of education provision through mobile schools.
Partial oxidation of hydrogen sulfide to sulfur over vanadium oxides bronzes

Me containing V 2 O 5 materials (Me Ag, Cu, Ca and Na) were prepared hydrothermally (from aqueous gels containing V 2 O 5 /H 2 O 2 /MeCl x mixtures, with Me/V ratios of 0.17) The samples were finally heat treated in air or in N 2 atmosphere. The heat treated samples have been characterized by several physico chemical techniques and tested in the partial oxidation of hydrogen sulfide. According to XRD, electron paramagnetic resonance and 51 V NMR results, Ag 0.35 V 2 O 5 and Na 0.33 V 2 O 5 (or NaV 6 O 15 bronzes with a minority presence of V 2 O 5 were mainly obtained in the case of Ag and Na containing materials in samples both heat treated in air or in N 2 atmosphere. In the case of Cu and Ca containing samples, V 2 O 5 was mainly observed in samples calcined in air. However, Cu 0.26 V 2 O 5 and Ca 0.17 V 2 O 5 bronzes, with the minority presence of V 2 O 5 have been observed in Cu and Ca containing samples heat treated in N 2 On the other hand, the catalytic behavior strongly depends on the metal promoter. Thus catalysts presenting vanadium oxide bronzes, i.e. samples presenting Ag 0.35 V 2 O 5 NaV 6 O 15 Cu 0.26 V 2 O 5 or Ca 0.17 V 2 O 5 shows a catalytic activity during the partial oxidation of H 2 S to sulfur higher than that observed over pure V 2 O 5 or over promoted catalysts presenting mainly V 2 O 5 (i.e. Cu or Ca containing samples calcined in air) Moreover, some differences in the selectivity to sulfur were observed. A higher formation of SO 2 at high reaction temperature has been favored over Ag 0.35 V 2 O 5 containing catalyst. This different behavior between samples could be explained by the presence of metallic Ag on the surface of Ag 0.35 V 2 O 5 which was detected by XRD. Also, higher formation of SO 2 is favored in the case of catalyst heat treated in N 2 in which the presence of VO 2 as minority, could have a role in combustion of sulfur. Accordingly, this work should be considered as a first approach to relate catalytic activity of the Me containing vanadium oxide bronze (containing Ag, Cu, Ca and Na) for the selective oxidation of hydrogen sulfide.
