A Review of Leadership Theories, Principles and Styles and Their Relevance to Educational Management

Rose Ngozi Amanchukwu, Gloria Jones Stanley, Nwachukwu Prince Ololube

Management, 2015, 5(1), pp. 6-14

DOI: 10.5923/j.mm.20150501.02

This study was motivated by the premise that no nation grows further than the quality of its educational leaders. The purpose of this theoretical debate is to examine the wider context of leadership and its effectiveness towards improving school management. This academic evaluation examines recent theoretical developments in the study of educational leadership in school management. It begins with a concise overview of the meaning and concept of leadership in terms of research, theory, and practice. This is followed by an examination of the theories of leadership, principles and styles of leadership. Each section ends with an identification of contemporary issues and possible means of amelioration. This article concludes that success is certain if the application of the leadership styles, principles and methods is properly and fully applied in school management because quality educational leadership tradition offers great opportunity to further refine educational leadership and management policies and practices by accepting and utilizing the basic principles and styles of educational leadership.

Internet of Things: Ubiquitous Home Control and Monitoring System using Android based Smart Phone

Rajeev Piyare

International Journal of Internet of Things, 2013, 2(1), pp. 5-11

DOI: 10.5923/j.ijit.20130201.02

This paper presents a low cost and flexible home control and monitoring system using an embedded micro-web server, with IP connectivity for accessing and controlling devices and appliances remotely using Android based Smart phone app. The proposed system does not require a dedicated server PC with respect to similar systems and offers a novel communication protocol to monitor and control the home environment with more than just the switching functionality. To demonstrate the feasibility and effectiveness of this system, devices such as light switches, power plug, temperature sensor and current sensor have been integrated with the proposed home control system.

Aqueous Two Phase Systems for the Recovery of Biomolecules – A Review

Selvaraj Raja, Vytla Ramachandra Murty, Varadavenkatesan Thivaharan, Vinayagam Rajasekar, Vinayagam Ramesh

Science and Technology, 2011, 1(1), pp. 7-16

DOI: 10.5923/j.scit.20110101.02

Aqueous two phase system (ATPS) is a liquid – liquid extraction method which employs two aqueous phases having applications in the field of biotechnology for the separation and purification of biological materials such as proteins, enzymes, nucleic acids, virus, antibodies and cell organelles. This review discusses the basic principles of ATPS, the factors affecting partitioning, optimization by design of experiments and the recent applications like extractive fermentation, membrane supported liquid – liquid extraction and aqueous two phase floatation. A comparative study between ATPS and other conventional methods is also discussed. The emphasis is given to PEG/salt two-phase systems because of the low cost of the system.
