The role of emotions and beliefs in developing language teacher\u27s professional identity

Many studies have investigated different positive and negative emotions that teachers experience in their work place, in addition to their teaching beliefs. However, none of these studies addressed the role of these emotions in formulating teaching beliefs and how both emotions and beliefs shape teacher’s professional identity; particularly in an Egyptian context. The current study addresses this gap. The participants are seven female experienced teachers who work in different private institutions, under different instructional settings. The study uses semi -structured interviews, narratives and focus group discussion as data collection tools. Lazarus psychological theory of emotions (1991) was used to analyze emotions. The beliefs analysis was guided by Borg (2001) and Goodman (1998) frame works and Gee (2001) levels of identity were found to reflect teacher’s professional identity. The results showed that teachers’ emotions affected their beliefs in relation to their students, their own teaching, the institution they work at and their colleagues. The results also implied that emotions and beliefs affected the development of those teachers’ professional identities in three main contexts; student-related, institution-related and their teacher self-related contexts. The study suggests some pedagogical implications if implemented in teachers’ education programs, would help them to develop sense of awareness of their weaknesses and strengths, reconsider their beliefs, whenever urging to do so, and hence the development of their professional identities

Existence theorems for nonlinear differential equations having trichotomy in Banach spaces

summary:We give existence theorems for weak and strong solutions with trichotomy of the nonlinear differential equation \dot {x}(t)=\mathcal {L}( t)x(t)+f(t,x(t)),\quad t\in \mathbb {R}\leqno {\rm (P)} where $\{\mathcal {L}(t)\colon t\in \mathbb {R}\}$ is a family of linear operators from a Banach space $E$ into itself and $f\colon \mathbb {R}\times E\to E$. By $L(E)$ we denote the space of linear operators from $E$ into itself. Furthermore, for $a0$, we let $C([-d,0],E)$ be the Banach space of continuous functions from $[-d,0]$ into $E$ and $f^{d}\colon [a,b]\times C([-d,0],E)\rightarrow E$. Let $\widehat {\mathcal {L}}\colon [a,b]\to L(E)$ be a strongly measurable and Bochner integrable operator on $[a,b]$ and for $t\in [a,b]$ define $\tau _{t}x(s)=x(t+s)$ for each $s \in [-d,0]$. We prove that, under certain conditions, the differential equation with delay \dot {x}(t)=\widehat {\mathcal {L}}(t)x(t)+f^{d}(t,\tau _{t}x)\quad \text {if }t\in [a,b],\leqno {\rm (Q)} has at least one weak solution and, under suitable assumptions, the differential equation (Q) has a solution. Next, under a generalization of the compactness assumptions, we show that the problem (Q) has a solution too

Investigating the Impact of Omni-Health Integration on Waiting Time in Healthcare Centers

One of the most crucial steps in improving the patient experience is to reduce outpatient wait times. Patientswait for long periods of time for a physician to attend to them due to a lack of a functioning system. HealthCare Centers can benefit from an omni-health approach that enables patients to make payments and completeother necessary tasks before their visit to reduce patient wait time. This study aims to investigate whetherthe Omni health approach can benefit in reducing the wait time of patients. The Random Forest Regressionand correlation analysis have been carried out. To remove biases, this study also included other factorssuch as the number of office-staffs, number of physicians, number of equipment, and costs. The RandomForest Regression shows that Omni health integration is crucial to reduce the wait-time of the patients.However, the number of office-staffs, number of physicians, number of equipment are also importantfactors in reducing the wait time. The cost factor is found to be the least important factor in reducing thewait time. Our results suggest that that the health care center should increase the integration of the Omni- healthapproach to reduce the wait time and to improve the experience of health center clients

Construction Industry and HR Audit: Could it Support the Organizational Objectives and Strategies? A Case Study from the Egyptian Market

It is a usual thing for construction companies to have multiple projects progressing in synchronization with each other and covering multiple geographical locations. With such nature of work, the burden on the HR department gets heavier than usual in assuring that the department, with its diversified activities and locations, is linked to the top strategies and objectives of the business. This is a case study of a construction company human resource function in an endeavor to link such function with the overall business objectives and strategies. To achieve this, there would be an analysis and evaluation of the dominant organizational culture, and a use of the Human Resource Audit tool to make a detailed assessment of the current human resource function situation. By doing so, results obtained by both analyses are used as a guideline in developing a model of human resource department’s strategies and plans oriented with the overall business’ objectives and strategies. The design chosen for this research is the Case Study that would point out the issues of concern within the company, and hence, use the findings in achieving the objectives.

Positioning and Smoothing Movement Approaches of a Linear Actuator Dedicated to A Biomedical Application

The movement of linear stepper motors is characterized by a highly oscillatory translation, which is troublesome for the positional accuracy and the speed constant (often required by many industrial applications such as the syringe pump). These oscillations can lead to loss of synchronism and stall risk. Thus, in order to attenuate the amplitudes of these oscillations and to guarantee the positioning of the actuator without errors, solutions exploiting open-loop and closed-loop control techniques are proposed in this paper for the purpose of improve the performance of the actuato

Examining the Impact of Omnichannel retailing on Buying Intention Using Binary Models

The last decade showed that the customer journey is no longer linear and now contains numerous touchpoints. Omni-channel retailing intends to provide a smooth retail experience irrespective of where the consumer is on the internet or in-store, and which device they are using, or which channel they are accessing content through. The objective of this study was to check whether the integration of omnichannel has any impact on the buying intention of consumers in retail stores. The study used Probit and Logistic model to fulfill the study objective. The results show that omnichannel integration in retail stores has a significant positive impact on buying intention. Moreover, the results also show that the quality of the product, brand image, and social influence has a significant positive impact on the buying intention in the context of retail stores. This study recommends that retail stores can influence the buying intention of consumers by implanting an effective omnichannel strategy

Geometric Parameter Optimization of Switched Reluctance Machines for Renewable Energy Applications using Finite Element Analysis

The choice of SRM design depends on the specific application and performance requirements. Factors such as power output, torque characteristics, and efficiency will all influence the choice of SRM design. To find an optimal geometry, it is therefore necessary to determine the effect of each parameter such as rotor pole angle, stator pole angle, stator external diameter, rotor diameter, air gap length, rotor yoke, stator yoke and shaft diameter on the machine performance. For this reason, this paper discusses a comparative study of the geometric parameters influence on SRM performance. The analysis is performed by finite element simulations based on the variation of rotor inclination, air gap length, stator and rotor polar arc variations of three machine topologies such as the three-phase 12/8 SRM, three-phase 6/4 SRM and four-phase 8/6 SRM. For a reliable comparison, these machines must have the same basic dimensions (stator outer diameter, rotor outer diameter and length) and operate in the same magnetic circuit saturation. Graphical and numerical results of torque and magnetic flux for three SRM topologies are highlighted. The presented study aims to provide reliable results on the dimensions to be adjusted for various applications
