Novel Dynamic Scaling Algorithm for Energy Efficient Cloud Computing

Huge data processing applications are stored efficiently using cloud computing platform. Few technologies like edge computing, Internet of Things (IoT) model helps cloud computing framework for executing data with less energy and latencies for better infrastructure. Recently researches focused on providing excellent services to cloud computing users. Also, cloud-based services are highly developed over IT field. Energy a level varies based on the cloud setup like speed, memory, service capability and bandwidth. The user job requirements are varied based its nature. The process of identifying efficient energy resources for the user job is main aim of this research work. Initially IoT, Edge devices capture the job and process to help cloud infrastructure. Data transferring process is a Non-deterministic Polynomial (NP) hard problem which can be easily supported by technologies like IoT and Edge computing. Main issue is, tremendous increase of data over the cloud causes difficult to manage consumption of energy. In this research work server clouds with edge devices and centralized cloud servers are combined to work for providing efficient energy consumption. Here, in this paper we implement novel dynamic speed scaling (NDS) algorithm. The CPU workload is first computed using NDS algorithm for incoming application. The less energy computation is achieved using energy internet of things (EIoT). Fine methodology called speed processor scaling, helps to consume less energy and less computation price. High energy consumption of processor is due to high computation speed. likewise, less energy is consumed during less processor computation speed. This technique is building in NDS algorithm and computed in Edge devices for less energy consumption. The result evaluation proves that proposed technique consumes only 10 s for data computation when compared to other existing techniques.

Investigating the Nature of Change in Factors Affecting Gender Equity in the IT Sector: A Longitudinal Study of Women in Ireland

How and why do societal, organizational and individual factors affecting gender equity in the IT field change over time? To answer this question a longitudinal investigation of the nature of change in factors affecting the position of women in the IT profession was undertaken. It was conducted in Ireland against the backdrop of fluctuations in the nation’s socio-economic status. The individual differences theory of gender and IT was used to analyze life history interviews conducted at four points in time with a total of 63 women whose stories cover the decades from the 1970s to the 2010s. What resulted is a dynamic extension of this theory through the addition of seven themes that characterize the nature of change in factors affecting women IT professionals. The effect on women of economic changes in Ireland is shown to occur through changes in other factors: environmental (i.e., policy, infrastructural, and cultural), identity (e.g., motherhood) and individual (e.g., family). The results reveal both gradual and dramatic changes in an evolving picture of women in this sector, against the back drop of the peaks and valleys of Ireland’s economy. Both transformational and enduring images emerge from this look at Ireland over five decades.

From Knowledge-Driven to Learning- Driven -The Importance of Workplace Learning

Workplace learning is not only essential for the operation and development of the knowledge economy, but also an important factor in lifelong learning. Moreover, it is one of the most emphasized areas of adult learning. In recent decades, we have also witnessed the fact that school‐based education and training lose their importance while individual learning becomes the dominant knowledge acquisition process and activity in adulthood. Our qualitative research is based on interviews with 23 IT companies operating in Hungary. This sector was chosen because the IT field belongs to the knowledge‐intensive sector, so workplace learning processes can be well studied. The focus of the research is on the learning processes generated by the knowledge gaps in organizations. How does the need for arise? From what sources and in what ways do those working in the organization obtain the necessary information and knowledge? How will the acquired knowledge affect life in the organization? The results of the research enrich the fields of both lifelong learning and adult learning research, and they also contribute to some extent to knowledge management approach.

Платформа MOODLE як інструмент реалізації дистанційного навчання у процесі підготовки майбутніх учителів іноземних мов

Introduction. The training of future foreign language teachers should focus on current advances in the IT field, in particular on the use of elements of distance learning in mastering professional and general competencies. One of the common learning management systems that provide distance education is the Moodle system –Learning Management System(LSM), courses, virtual learning environment, or just a learning platform that provides educational subjects and administrators with a large set of tools for computerized teaching and learning. Purpose. The purpose of the paper is to analyze the features and advantages of distance learning in the information and educational environment of higher education, the structure and principles of working with distance courses in the Moodle system during the training of future teachers of foreign languages, which is used at Mariupol State University, and also to determine the advantages of the Moodle learning management system in the educational process. Results. We believe that the Moodle system, which was developed in the logic of the “pedagogy of social constructionism” (P. Berger and T. Lukman), is able to significantly increase the level of education if the work of students is properly organized in it: it will create a solid base and allow to prepare a specialist who is well trained and possesses competencies at a high level. On the example of our distance course “Methodological workshop” for students of OS Master in specialty 014 Secondary education “Language and Literature (English)”, which organically combines the theoretical principles and practice of teaching English, as well as in-depth study of the courses“Methods of teaching basic foreign language in secondary education”and“Modern technologies for teaching a basic foreign language (English) in high school”, which have practical importance in the professional development of future specialists, we analyzed the productivity of work organization and the effectiveness of students learning in Moodle, using the principle of “constructive coordination” (John Biggs). In its construction, we approached the planning of the entire process of studying the discipline as a set of interconnected types of educational activities of students. The principle of “first content, then technology” works here. This course contains three components that are consistent with each other: 1) expected learning outcomes, consistent with the objectives of the educational program and programmatic learning outcomes; 2) assessment, which verifies certain learning outcomes; 3) all types of activities during the course that are aimed at achieving learning outcomes. Conclusion. According to online surveys and our own experience, the use of distance learning courses created in the Moodle system in the educational process of students allows them to better study a specific academic discipline, helps to improve students’ achievement; complements enriches and makes the learning process convenient for both students and teachers.

Peculiarities of the correlation between professional well-being and organizational commitment of information technology specialists


 
 
 The article analyzes the problem of the correlation between professional well-being and organizational commitment of specialists in the field of IT in Ukraine. The concept of "professional well-being" is defined as the psychological state of the employee associated with the efficiency and productivity of his work; the concept of "organizational commitment" as an emotional attachment, identification with the norms and values of the organization, acceptance of goals, excessive work in the interests of the company. The professional well-being was studied according to the method of "Professional well-being" K. Ruth (indicators: autonomy in professional activity, competence, professional growth, positive relations in the team, professional goals, acceptance of oneself as a professional, general indicator); and organizational commitment according to the method of "Professional demand for personality" O. Kharitonova (indicators: satisfaction with the realization of professional potential, belonging to the professional community, experiencing professional demand, professional competence, professional authority, evaluation of professional results, attitude to others, self- esteem and general indicator of personal demand in the professional plan) and the Questionnaire of J. Meyer and N. Allen "Scale of organizational commitment" (indicators: affective loyalty, normative loyalty, continuance loyalty). The correlation between professional well-being and organizational commitment has been empirically identified by correlation analysis. Loyalty scales have been found to be negatively correlated with professional well-being scales, suggesting that the more competent an IT professional considers himself, the less likely he is to become loyal to an organization. It is concluded that the structure of professional well-being and commitment to the company of IT employees has its own characteristics and requires more detailed further research.
