A Data Driven Model for Predicting the Financial Market Prices for Investors with Non Financial Experts: The Case of Saudi Arabia

The Fama and French (FF) three factors model has been one of most famous models in explaining the returns of stocks. This study investigates if the three factors of the FF model at the micro level may impact the return of portfolios in Saudi Arabia Stock Exchange (SASE) using an accurate modern technique in forecasting: Artificial Neural Networks (ANN). This study examined monthly data relating to common stocks from the listed companies of Saudi Arabia Stock Exchange from January 2007 to December 2011. The results from this study indicate that the FF model is applicable to measure the Stocks and portfolios reruns. Also, ANN technique can be used in predicting the stock and portfolios returns.

Embracing Social Media to Engage Students and Teach Narrative Writing.

I initially experimented with the following activity in a graduate-level Creative Writing course at Cadi Ayyad University in Marrakech, Morocco. Working through a unit on narrative fiction and short stories, students were developing their narrative-writing skills in what was, for many, the first time they had written an entire short story. After reading a few short stories and discussing the “essentials” of plot, character, setting, theme, and point of view, students set out to write their own piece of fiction. Yet, even for advanced-level graduate students, the task was daunting. The idea of breaking away from “academic writing” and “intellectual dialogue” was unsettling. A writing task that I had imagined would be a fun and creative break from the norm turned out to be, for many students, an anxiety-ridden plunge into uncertainty.
Parallelization of SIFT on Rigel

With the trend towards parallel processing in computing, interest is developing in enabling workloads to be done at faster speeds to enable new usage models. SIFT is an algorithm for image detection and can be used for a variety of purposes. It collects key-point features that are invariant to changes in lighting, orientation and affine transforms. We ported the SIFT algorithm to the many-core architecture Rigel and studied the amount of speedup that can be gained by parallelizing the algorithm. Our results showed the algorithm to provide a speedup of 75x when parallelized over 128 cores.
Ethnicity Moderates the Relationship Between Perceived Social Support and Self-Care Confidence in Heart Failure Patients

Summary: The purpose of this data analysis was to examine the relationship between perceived social support and self-care confidence in a sample of patients with Heart Failure Content Outline: Content Outline: “Ethnicity Moderates the Relationship Between Perceived Social Support and Self-Care Confidence in Patients with Heart Failure” • Introduction o Main Point#1 – Heart failure (HF) affects approximately 6.5 million people in the United States 1 and is a chronic disease that leads to high healthcare costs and rehospitalizations. ▪ Re-hospitalization is often a result of inadequate self-care.2 ▪ Poor overall self-care, low self-care confidence (SCC) and lower levels of perceived social support (PSS) are factors related to increased risk for hospitalizations in HF. o Main Point #2 – African Americans have the overall highest risk of developing HF and have a more progressive disease trajectory.3 ▪ African Americans are hospitalized seven to eight times more often than Caucasians.4,5 ▪ Ethnic differences related to HF exist not only in health outcomes, but also in HF self-care and social support.3 o Main Point #3 Previous investigators reported that SCC is a moderator of self-care ability in people with HF, however, little is known regarding the factors that may impact SCC in people with HF. • Methods o Measures ▪ Patients with HF completed measures of PSS (Multidimensional Scale of Perceived Social Support) and SCC (Self-Care of Heart Failure Index; Self-Care Confidence Subscale). ▪ Patients included in this analysis were either African American or Caucasian. o Statistical analysis Moderation analysis was conducted using hierarchal linear regression. • Results o The mean age of the sample (N = 429) was 60.8 + 11.5, 68% were male, and 54.7% were New York Heart Association class I or II. o Results from moderation analysis yielded a significant interaction of PSS and ethnicity. o In African American patients, there is a non-significant relationship between perceived social support and self-care confidence, b = -0.776, 95% CI [-0.049, 0.060], t = 0.212, p = 0.832. o In Caucasian patients, there is a significant positive relationship between perceived social support and self-care confidence b = -0.224, 95% CI [0.046, 0.094], t = 5.65, p <. 001. • Discussion/Conclusion o Ethnicity may play an important role in PSS and SCC in patients with HF. o Our results show there was no change in self-care confidence scores as levels of perceived social support increased in African American patients. o Conversely, Caucasian patients demonstrated higher self-care confidence scores as level of perceived social support increase. Further research is needed to develop and test interventions that are tailored to the ethnicity and levels of social support in patients with HF.
The LGBTQ Supportive Environments Inventory: Methods for quantifying supportive environments for LGBTQ youths

Abstract The social environment in which lesbian, gay, bisexual, transgender, and queer (LGBTQ) youths live influences health and well-being. We describe the development of the LGBTQ Supportive Environments Inventory (LGBTQ SEI), designed to quantify the LGBTQ-inclusiveness of social environments in the United States and Canada. We quantify aspects of the social environment including: (1) presence/quality of LGBTQ youth-serving organizations; (2) LGBTQ-inclusive community resources; and (3) socioeconomic and political environment. Using geographic information systems (GIS) tools, we aggregated data to buffers around 397 schools in three regions. The LGBTQ SEI can be used to assess the role of the social environment in reducing health disparities for LGBTQ youths.
Effective Joint Regularization in Medical Imaging for Nonsmooth Nonlinear Priors

This thesis describes methods for medical image registration, denoising and anatomy reconstruction. We develop and investigate a broad range of regularization approaches to improve accuracy of the provided estimates. The formulated problems are then solved within an optimization framework based on the method of multipliers. Smoothness priors are conveniently used in medical imaging, as they provide tractable formulation of the optimization problem. However they generally reduce the resolution of the estimate due to the oversmoothing of the initial problem. More flexible regularizations (such as total variation) do allow discontinuities, but at the cost of complicated numerical optimization schemes. In this work we exploit recent advances in mathematical optimization to allow efficient implementation of such flexible regularizations by adopting the method of multipliers for medical imaging tasks. To further improve plausibility of the provided estimates, we develop and present regularizations that are aimed to impose prior knowledge in a joint fashion. We employ and adapt different formulations of the total variation measure to tackle problems of image registration and denoising. Transformation consistency over loops is then used to determine the correctness of registrations in the cases of linear and nonlinear displacement fields, yielding a novel consistency models. A sparsity inducing regularization is employed to account for possibly uncompensated cardiac motion for the denoising of in vivo diffusion weighted images. Specialized regularization was developed to jointly account for the helical myofiber architecture and the uncertainty of the diffusion estimates. All methods have been evaluated on clinical images from different modalities (CT, MRI and DW-MRI) and different anatomies (thorax, abdomen, cardiac, corpus callosum). The accuracy of the resulting estimates was shown to be improved compared to the generic and specialized state of the art methods.
A New Method for Face Pose Interaction in Virtual Environment

A new method is proposed for face pose estimation based on the area ratio in the paper.First,the change of triangle area ratio which consist of feature points is analyzed when a face turns.Then,the BP neural network is applied to train the relationship between position parameters of area ratio of face and the parameters of pose for face pose estimation.Finally,the method is applied to roam in the virtual environment.The experimental results demonstrate that this method can estimate accurately pose using only few characteristic points,and also does well in recognition rate and stability.
The Relationship between College Teachers' Occupation Efficiency and Well-being Research

The paper explores the relationship between occupation efficiency and well-being and the mediating effect of job burnout. A total of 507 college teachers were investigated by Maslach Burnout Invertory (MBI), Occupation Efficacy Questionnaire and General well-being Scale (GWBS). And results are as follows: (1)Every factor's scores of occupation efficacy was higher than the theoretical average(Ps<0.001), teaching prestige has the highest score followed by teaching ability and knowledge quality, research quality, and stable self-esteem. (2) 82.05% of the college teachers have job burnout, and every factor's scores of job burnout was higher than the theoretical average (Ps<0.001). (3) Job burnout was negatively correlated with occupation efficiency and well-being (Ps<0.001), and occupation efficiency was significantly positively correlated with well-being (p<0.001). (4) The mediatory effect of job burnout between occupation efficiency and well-being was significant and proportion of mediatory effect in total effect was 53.99%. As a result, for college teachers, occupation efficiency was high and job burnout was serious. Job burnout partially mediated the relationship between occupation efficiency and well-being. 1. Question Raising Well-being as an index to evaluate individual’s social life quality and mental health, usually refers to individual’s gross satisfaction of their life condition and their evaluation of emotional condition [1]. Work is an essential part of people’s life, working ability, achievements and satisfaction influence people’s well-being greatly. Professional self-efficacy, also called career self-efficacy is a core concept that professional psychologists Hackett and Betz apply Bandula’s self-efficacy theory to professional behavior research. Career self-efficacy (CSE) refers to individual’s confidence and belief formed through judgement and evaluation of own professional ability based on comprehensive information rather than a specific personality trait or professional behavioral ability itself. It reflects individual’s confidence and belief ton the ability and perception to complete a specific professional task or achieve professional behavior goal [2]. Researches on teacher’s career self-efficacy mainly focus on teaching efficacy with research object as primary and middle school teachers [3-4]. There are few researches on teachers’ self-efficacy especially college teachers. Job burnout, also called work burnout, work exhaust, and professional exhaust, etc. was proposed by American psychologist Freudenberger in 1970s, which refers to a chronical comprehensive response due to continuous pressure from work including emotional exhaustion, deindividuation, and reduced self-achievability [5]. Teachers’ job burnout occurred frequently. This research will discuss the relationship between teachers’ career self-efficacy, subjective well-being and job burnout through investigation on college teachers.
An Analysis of Security Problems of Routing Protocols in Wireless Sensor Networks

The primary goal of current routing protocols for wireless sensor networks(WSNs) is to improve the energy efficiency while guarantee the required communication.Almost all of these protocols do not take security into consideration.As a result,many potential security problems exist in such protocols that they may be vulnerable to various attacks and cannot be applied to many fields.An illustration of various attacks on routing protocols is presented first.Then the security problems of typical protocols are analyzed.Finally attacks to which each of these protocols can be susceptible are found respectively.
Healthy and pathological aspects of parenting among Iranian families: A qualitative research

The aim of this study was to investigate the health and pathological aspects of parenting in Iran. This study has a qualitative design and the method used is Grounded Theory (GT). The population consisted of all Muslim parents with children over 10 years of age, living in Tehran and Karaj during the summer of 2016 to the summer of 2017. The sample contained 44 Muslim parents who were studied through semi-structured interviews. The interviews’ data analyzed based on Grounded Theory model and eventually, the result consisted of open, axial and, selective coding, 216 initial codes, 9 concepts and 3 cluster. In the axial analysis of the initial codes, 9 concepts(parenting styles) were extracted: rejection; kindness/support; over protection; inflexibility; optimum structure; chaos; coercion; assertiveness; autonomy support; negligence/passivity. These concepts can be conceptually distinguished although they have common features. In the following analysis and selective coding, 9 concepts are integrated around 3 major axis: intimacy (rejection; kindness/support; over protection); structure/law (inflexibility; optimum structure; chaos); autonomy/freedom of action (coercion; assertiveness; autonomy support; negligence/passivity). Of the three concepts that were organized around each axis, the medium concept draws a balanced and healthy situation and two other concepts represent the pathological aspects of that axis. The results of this study showed that most of the parents involved in the study used a kind of authoritarian parenting style (the combination of over protection, inflexibility and coercion). Healthy parenting (the combination of kindness/support, optimum structure and autonomy support) is in second rank.

Explorations into the social contexts of neologism use in early
 English correspondence

This paper describes ongoing work towards a rich analysis of the social contexts of neologism use in historical corpora, in particular the Corpora of Early English Correspondence, with research questions concerning the innovators, meanings and diffusion of neologisms. To enable this kind of study, we are developing new processes, tools and ways of combining data from different sources, including the Oxford English Dictionary, the Historical Thesaurus, and contemporary published texts. Comparing neologism candidates across these sources is complicated by the large amount of spelling variation. To make the issues tractable, we start from case studies of individual suffixes (-ity, -er) and people (Thomas Twining). By developing tools aiding these studies, we build toward more general analyses. Our aim is to develop an open-source environment where information on neologism candidates is gathered from a variety of algorithms and sources, pooled, and presented to a human evaluator for verification and exploration.
A short note on the rationality of the false consensus effect

In experiments which measure subjects’ beliefs, both beliefs about others’ behavior and beliefs about others’ beliefs, are often correlated with a subject’s own choices. Such phenomena have been interpreted as evidence of a causal relationship between beliefs and behavior. An alternative explanation attributes them to what psychologists refer to as a ‘false consensus eﬀect’. It is my impression that the latter explanation is often prematurely dismissed because it is thought to be based on an implausible psychological bias. The goal of this note is to show that the false consensus eﬀect does not rely on such a bias. I demonstrate that rational belief formation implies a correlation of behavior and beliefs of all orders whenever behaviorally relevant traits are drawn from an unknown common distribution. Thus, if we assume that subjects rationally update beliefs, correlations of beliefs and behavior cannot support a causal relationship.

Physical Education students’ beliefs in four important curricular outcomes: results from three Greek Faculties

Purpose: This study aimed to investigate Physical Education (PE) students’ belief systems toward the four important curricula outcomes goals (physical activity and fitness, self-actualization, motor skill development and social development) and to compare these beliefs according to gender and undergraduate Faculty program attended. Method: 690 Students from the three major PE Faculties in Greece were enrolled (465 males, 225 females). They completed a previously validated four-factor belief systems instrument. Results: Internal consistency reliability for the instrument was . 915. A confirmatory factor analysis demonstrated a good fit of the current sample to the hypothesized four-factor outcomes model. The students did not view the outcome goals as equally important. The prevailing goal was physical activity and fitness, followed by self-actualization. Multivariate analysis of variance results for comparisons between sub-groups revealed significant differences between genders and undergraduate programs attended. Discussion/Conclusion: The findings, coupled with those of previous researches, imply that PE students form their beliefs mostly based on their previous experiences. These beliefs appear to be very solid and thus, undergraduate studies seem to have a small effect on their formation and modification.

Case report: A successful re-challenge report of GLS-010 (Zimberelimab), a novel fully humanized mAb to PD-1, in a case of recurrent endometrial cancer

With the widespread use of immune checkpoint inhibitors (ICI), there is growing concern about reports of immune-related adverse events (irAE). In clinical practice, patients who experience severe toxicities by ICI-based therapies would require utmost caution in resuming ICI therapy because of the potential risk of serious irAEs caused by the reintroduction of immunotherapy. In this study, we report a case of recurrent endometrial cancer patient with PD-L1 positive as well as dMMR suffering from immunotherapy-associated myocarditis after first-line treatment with ICI combined with a multi-targeted anti-angiogenic agent. After symptomatic treatment, the patient was in complete remission from treatment toxicities. Subsequently, through MDT discussions, we selected a new PD-1 agent, zimberelimab, for rechallenge therapy, and the patient achieved a sustained disease remission without any treatment-related toxicities. To date, the manner and timing of the ICI re-challenge has been a subject of iterative deliberation. We believe that our experience could shed some light on ICI rechallenge therapy, and we look forward to more literatures to refine the ICI rechallenge scenarios.

Challenges Facing Women in School Leadership Positions: Experiences from a District in Zimbabwe

Successful educational leadership entails possessing the knowledge, skills and understanding of effective leadership skills along with the personal ability to effectively implement those skills. In Zimbabwe the occupational and leadership status of women in general is still suffering a wide gap, as there is unequal representation in leadership positions between men and women. This study, conducted in a rural district in Zimbabwe, aimed at understanding the challenges facing women in school leadership positions. In this article we argue that there are cultural, social and structural domains among others that impede the effective operations of women in school leadership positions. Using a qualitative research paradigm, six schools in one rural district were chosen for the study. A semi-structured interview guide was used to collect data from six female heads - three from primary schools and three from secondary schools. Focus group discussions were held with teachers from the same schools. The study established that there are cultural, structural, economic and social barriers facing women in school leadership positions. We recommend that different strategies should be set up for developmental programs for women in leadership positions.
