Spending profiles of sultan idris education university undergraduates: a CHAID-based segmentation

Issues on college students spending behaviour have been studied numerous times due to improper use of education funds. Various studies examined determinant factors for this misbehaviour in order to understand, identify and recommend ways to educate these future generations. Some documented relationships between financial behaviours and financial literacy, money beliefs and socialization agents. This study walks the same path but focuses on spending behaviour rather than financial behaviour and examines its association with determinant factors by means segmentation analysis. The aim of the study is to profile Sultan Idris Education University undergraduates’ according to their spending using a decision tree analysis procedure called Chi-squared Automatic Interaction Detector (CHAID). CHAID generates predictive tree models by segmenting based on predictor variables which include demographic characteristics, program of study related traits and funding aspects that were utilized to profiles students’ spending. Spending in this study excludes most incurred expenditures namely living and subsistence costs. Spending profiles were determined based on 751 feedbacks received from business students of Sultan Idris Education University. It was found that, top five most incurred non-subsistence expenses were personal hygiene products, study materials, telecommunications services, clothing and health products. Interestingly, all these five types of spending can be segmented according to only one predictor variable namely, faculty. It can be assumed from this results that, spending profiles are shared within the same faculty. Since spending profiles can be differentiated between faculties, it can be recommended that education programs directed at influencing spending behaviour should be tailor-made according to faculties.
Análise de Sentimentos em comentários na língua portuguesa: uma comparação de métodos

: This article presents a study on the sentiment analysis applied to films reviews dataset and news comments dataset in Portuguese language, based on the comparison of performance indicators for an English language dataset. Two widely used feature engineering methods, the bag of words (BoW) and the word embedding (MWE), were applied. The results of the experiments show positive and negative aspects of both approaches and emphasize the power of word density in the performance indicator, both for the BoW method and for the word dictionary formulation of word embedding.

Cancer Therapy with the Aid of Nanotherapeutics

The utilization of polymeric micelles in providing optimal drug delivery against cancer has been thoroughly investigated and exhibits many promising facets, as evidenced by many research scientists all over the globe. The acceleration in the rapid development of these micelles as a robust delivery platform is primarily dictated by the fate of these micelles in vivo, which ultimately governs their stability profile and efficacy in the blood stream [1]. As a result of this ever-evolving interest in developing nanotherapeutics, several micellar based anticancer treatments are currently in advanced stages of clinical development [2]. Chemotherapeutic medications suffer from various limitations such as dose-limiting toxicities, unfavorable bio distribution profile and lack of therapeutic efficacy at the target site of action [3]. These inherent drawbacks can be alleviated by the judicious use of nanotherapy, particularly polymeric micelles. The therapeutic strategy of “magic bullet”, as envisioned by Paul Ehlrich, proposed that the delivery system will usher the pharmacologically active molecule to the site of interest with maximum accuracy and minimal distribution to the peripheral organs of elimination [4,5]. These nano particulate therapies have exhibited similar characteristics to this binding principle of magic bullet.
Curvature Angle Splitting Suppression and Optimization on Nonplanar Coils Used in Wireless Charging System

This article investigates the tapered and curved coil used in wireless power transfer (WPT) system for the purpose of improving flexibility in specific applications. The WPT transmission performance is always declined by coil bending. To solve this problem, the models of the coils are built, and their magnetic flux are analyzed. The phenomenon of curvature angle splitting is studied, the mechanism is revealed, and the method is proposed to avoid the splitting. Formulas are derived to determine whether the system is working in curvature angle splitting state. By optimizing the coil parameters to make the system work in critical splitting state, the maximum output power and excellent stability under different angles are achieved. Experimental results show that when the optimally designed receiver coil is bent in the range of 50°–130°, the maximum current change rate is only 4.3%. The study in this article will further promote the application of WPT technology in a wider range of fields.
Towards Multimodal Office Task Performance Estimation

The performance of human workers can be fluctuated due to changes in the cognitive state during sustained work. Though past researches have made human performance monitoring possible by utilizing physiological signals, little attention has been paid to the context of office works. This research proposes a multimodal approach to estimate office task performance. A transcription typing experiment was conducted to simulate the real working environment while typing speed and error rate represented as performance metrics. Physiological data collected during the experiment, together with conventional machine learning algorithms showed feasibility to accurately predict two levels (good/bad) of task performance. More importantly, a comprehensive comparison between choices of modality suggests that using data from particular sources could gain predictive performance comparable to the complete set of modalities.
Verticalization and gait training in burn patients

Introduction: Burns belong to the most dramatic injuries that may affect a human being. Due to their severe functional and aesthetic complications, they pose a serious challenge for physicians, physiotherapists and psychologists. The therapeutic process in patients after thermal injuries is difficult and involves a great risk, including a loss of life. The patients’ recovery to full ability requires their patience, engagement and regularity in practising rehabilitation exercises. Aim of the study: The aim of the study is a presentation of consecutive stages of patient verticalization after thermal burns and an assessment of their functional ability in general motor skills. The study is an attempt to describe the complex process of rehabilitation management to prepare a patient for verticalization on the basis of the authors’ own experience of work with burn patients. Material and methods: The study covered 95 patients, aged from 27 to 65, with burn injuries of grade IIb/III extending on over 30% of TBSA with accompanying lower limb burns. The group consisted of 15 women and 70 men. The hospitalization period ranged from 8 to 12 weeks. The surgical treatment in the study group involved fasciotomy, necrectomy, and skin autografts of medium thickness. All the patients were in danger of possible motor difficulties. The management included positional treatment, exercise adjusted to the treatment stage and to the patient’s ability, verticalization and gait training. For an evaluation of functional ability in general motor skills, the Rivermead Motor Assesment was applied. The Rivermead Mobility Index is a motor-functional scale that evaluates mobility and locomotion, e.g. position changing, transfers, gait and stair climbing ability. Conclusions: 1. Early verticalization is an important component of the therapeutic process in burn disease. 2. A patient’s adequate preparation for verticalization involves a range of obligatory procedures and rehabilitation measures. 3. Verticalization is a gradual process where the correct sequence of stages must be maintained.
The Role of Support Groups in the Management of Depression amongst People Living with HIV at Regional Hospital of Bamenda

Depression is the most common neuropsychiatric mental condition found among people living with HIV (PLHIV). Despite its high prevalence, depression remains under diagnosed amongst PLHIV, and determining its prevalence is very cumbersome. As a mental condition, it has been associated with increased comorbidity, non-adherence to HAART, suicidal attempts, unsafe sex practice, just to name a few. Support groups have been shown to play an important role in the improvement of the quality of life of PLHIV and could be a means of managing depressive symptoms that arise in their lifetime. The aim of this research was to assess the role of support groups in the management of depression amongst PLHIV at the Bamenda Regional Hospital (BRH). This was a hospital based, observational cross sectional and descriptive study used to gather information from, one hundred and fifty two (152) HIV positive patients sticking to appointments at the treatment centre of BRH. The patient health questionnaire 9 (PHQ-9) was the screening tool for depression. Minimal, mild, moderate, moderately severe and severe depression constituted the levels of depression in which participants with depressive symptoms felt. A score of nine and above (≥9) was considered positive for depression. Further, the role of support groups were assessed through other questions that constituted the questionnaire and the activities carried out in support groups were observed and compared to standards of practice. Analysis revealed that 29.61% (95% CI: 22.5% - 35.7%) were positive for depression, and 108 (71.06%) participants presented with depressive symptoms. The role of support groups to participants was that it helps them in adhering to medication, filling hopeful and aiding them in disclosing their seropositive status to family members. The student t-test: t (70, N = 71) = ? 0.468, p = 0.641, showed no significant difference amongst support groups attendees and non-attendees, however, they are important to PLHIV and its practice at the level of Bambui District Hospital should be improved.
Factors that influence the ways univrsity students think about referencing and related concepts

ABSTRACT The role and importance of referencing is underestimated and neglected by university students globally. Literature illustrate that poor referencing practices might contribute to the persistent rise of plagiarism in higher educational institutions all over the world. Persistent poor referencing practices observed among our students at one of the South African universities led me to examine the socio-educational and cultural factors that influence the ways university students think about referencing and related concepts. This study interviewed fifteen third and fourth year students from one South African University of Technology. Grounded theory coding revealed that despite different cultural and schooling backgrounds, the majority of the students received their first formal referencing training at the university. The students felt that the training provided at our university was not in-depth, practical or extensive enough. Students reported that the reading and writing practices in high school were limited to memorising and regurgitating chunks of text from authoritative texts without necessarily being encouraged to acknowledge sources of information. The students were used to being given all the information considered necessary by teachers in class, and therefore saw no need to search for information themselves. It is therefore imperative that students are introduced to extensive referencing training and be trained to think critically about what they read from the first year of their study through to postgraduate studies.
Inclusion and citizenship: Syrian and Palestinian refugees in Lebanon

ABSTRACT This article critically explores how laws and practices of states and international organisations attempt to control refugees, drawing upon conceptions of ‘biopower’ and ‘technologies of anti-citizenship’ (Foucault 1972). This is examined in the Lebanese context, which has an estimated 1.5 million Syrian refugees (HRW 2016a), in an overall population of approximately 6 million (Worldometers 2018) – including approximately 500,000 long-term Palestinian refugees (UNRWA 2018). Firstly, I consider how ‘embodiment’ and ‘vulnerability’ relate to constructions of the ‘citizen’ in law, where refugees are constituted as vulnerable bodies ‘out of place’. Secondly, I examine how public, legal and policy constructions affect the lived experiences of refugees in Lebanon. This entails a recognition of the multiple axes of exclusionary intersectionalities, where the ideal citizen is constructed as adult, male, heterosexual, able-bodied, ‘intellectually competent’, economically productive, as well as holding a legal status as a national of the state. Thirdly, I examine two refugee initiatives that aim to address the discriminations faced in education and society. Drawing on these different sources of evidence, the article advances the argument that through global technologies of ‘human security’ promoting (neoliberal) individual self-reliance, exclusion is nevertheless perpetuated through depoliticised discourses and practices of vulnerability and (non-) citizenship.
Acute and sub-acute sinus node dysfunction following pulmonary vein isolation: a case series

Abstract Six patients submitted to paroxysmal atrial fibrillation (AF) ablation presented with long post-reversion sinus pauses between a few hours to 2 months after their procedures, causing recurrent syncope or pre-syncope. Five patients required urgent pacemaker implantation. None of these patients had previous symptoms suggestive of sick sinus syndrome (SSS) or a history of symptomatic bradycardia. Acute or sub-acute sinus node dysfunction (SND) has only recently been suggested as a potential complication of AF ablation. In three of our patients, the sinus node artery (SNA) was exclusively left-sided, running along the high anterior left atrium in close proximity to the ostia of the left and right superior pulmonary veins. In a fourth case, the SNA originated from the right coronary artery and coursed along the high anterior left atrium close to the ostium of the right superior pulmonary vein. In the remaining two cases, a pre-procedural assessment of the SNA was not possible, although a post-procedural CT scan performed in one of these did not reveal any signs of the SNA. Overdrive suppression of the sinus node exacerbated by thermal injury to the SNA may have been implicated. This was supported by (i) the lack of symptoms/signs suggestive of SSS pre-ablation, (ii) post-ablation acute/sub-acute pronounced post-AF reversion sinus pauses, and (iii) the observation that the SNA coursed along areas typically ablated during an AF ablation. Although this case series is hypothesis-generating only, we hope it will raise the awareness for the occurrence of acute/sub-acute SND as a potential complication of AF ablation.
Fixed points for α-βE-Geraghty contractions on b-metric spaces and applications to matrix equations

In this paper, we introduce the notion of ? -? E-Geraghty contraction type mappings on bmetric spaces and prove the existence and uniqueness of fixed point for such mappings. These results are generalizations of the recent results in [Fulga and Proca, Fixed points for ? E-Geraghty contractions, J. Nonlinear Sci. Appl. 10 (2017), 5125-5131]. We give some examples illustrating the presented results. An application on matrix equations and numerical algorithms are also provided.
Factors Affecting Community-Based Tourism Development and Environmental Protection: Practical Study in Vietnam

Community-based tourism (CBT) is considered as one of the typical types of tourism towards sustainable development with three important goals such as bringing back economic benefits, protecting natural environment and preserving indigenous cultural values. Therefore, this paper analyzes the factors that affect community ecotourism development associated with environmental protection in emerging economies, including Vietnam, by the method of key and community tourism potential value assessment with 721 sample surveys. In this paper, we have applied to assess the key factors of tourism in Vietnam and other key points to have more comprehensive solutions to promote the development of community-based tourism with environmental protection. The article has used guest-based approach and method of assessing the key success factors. The results of researching factors to develop community tourist (impacting tourist community needs of tourists) by running Logit function have shown the great influence of factors such as: environmental protection (influence factor +3.585780, with a statistical significance of 99%), security and safety (+3.024816—statistical significance 99%) followed by infrastructure conditions & facilities for the community based tourism, the level of information etc… for your community based tourism needs. From the research results, we propose the following policy groups: 1) Developing guidelines for CBT, the first step as a basis for the development of community based tourism laws later; 2) Policies related to the implementation of planning, development of key community tourist areas and destinations; 3) Policies related to the development of community-based tourism associated with the protection of natural and cultural environments; 4) Policies related to tourism management; coordinating monitoring of community tourism resource points; policies related to the local community in community tourism development; 5) Policies related to human resource development; promotion work; developing community based tourism products.
Greater male than female variability in regional brain structure across the lifespan

For many traits, males show greater variability than females, with possible implications for understanding sex differences in health and disease. Here, the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) Consortium presents the largest-ever mega-analysis of sex differences in variability of brain structure, based on international data spanning nine decades of life. Subcortical volumes, cortical surface area and cortical thickness were assessed in MRI data of 16,683 healthy individuals 1-90 years old (47% females). We observed significant patterns of greater male than female between-subject variance for all subcortical volumetric measures, all cortical surface area measures, and 60% of cortical thickness measures. This pattern was stable across the lifespan for 50% of the subcortical structures, 70% of the regional area measures, and nearly all regions for thickness. Our findings that these sex differences are present in childhood implicate early life genetic or gene-environment interaction mechanisms. The findings highlight the importance of individual differences within the sexes, that may underpin sex-specific vulnerability to disorders.
A stochastic-statistical residential burglary model with independent Poisson clocks

Residential burglary is a social problem in every major urban area. As such, progress has been to develop quantitative, informative and applicable models for this type of crime: (1) the Deterministic-time-step (DTS) model [Short, D’Orsogna, Pasour, Tita, Brantingham, Bertozzi & Chayes (2008) Math. Models Methods Appl. Sci. 18, 1249–1267], a pioneering agent-based statistical model of residential burglary criminal behaviour, with deterministic time steps assumed for arrivals of events in which the residential burglary aggregate pattern formation is quantitatively studied for the first time; (2) the SSRB model (agent-based stochastic-statistical model of residential burglary crime) [Wang, Zhang, Bertozzi & Short (2019) Active Particles, Vol. 2, Springer Nature Switzerland AG, in press], in which the stochastic component of the model is theoretically analysed by introduction of a Poisson clock with time steps turned into exponentially distributed random variables. To incorporate independence of agents, in this work, five types of Poisson clocks are taken into consideration. Poisson clocks (I), (II) and (III) govern independent agent actions of burglary behaviour, and Poisson clocks (IV) and (V) govern interactions of agents with the environment. All the Poisson clocks are independent. The time increments are independently exponentially distributed, which are more suitable to model individual actions of agents. Applying the method of merging and splitting of Poisson processes, the independent Poisson clocks can be treated as one, making the analysis and simulation similar to the SSRB model. A Martingale formula is derived, which consists of a deterministic and a stochastic component. A scaling property of the Martingale formulation with varying burglar population is found, which provides a theory to the finite size effects. The theory is supported by quantitative numerical simulations using the pattern-formation quantifying statistics. Results presented here will be transformative for both elements of application and analysis of agent-based models for residential burglary or in other domains.

Real-Time Implementation of Optimal Energy Management in Hybrid Electric Vehicles: Globally Optimal Control of Acceleration Events

Widely published research shows that significant fuel economy improvements through optimal control of a vehicle powertrain are possible if the future vehicle velocity is known and real-time optimization calculations can be performed. In this research, however, we seek to advance the field of optimal powertrain control by limiting future vehicle operation knowledge and using no real-time optimization calculations. We have realized optimal control of acceleration events (AEs) in real-time by studying optimal control trends across 384 real world drive cycles and deriving an optimal control strategy for specific acceleration event categories using dynamic programming (DP). This optimal control strategy is then applied to all other acceleration events in its category, as well as separate standard and custom drive cycles using a look-up table. Fuel economy improvements of 2% average for acceleration events and 3.9% for an independent drive cycle were observed when compared to our rigorously validated 2010 Toyota Prius model. Our conclusion is that optimal control can be implemented in real-time using standard vehicle controllers assuming extremely limited information about future vehicle operation is known such as an approximate starting and ending velocity for an acceleration event.
