Challenging Assumptions for Strategic Information Systems Planning: Theoretical Perspectives

A number of well-documented, fundamental assumptions are associated with strategic information systems planning (SISP). A core activity for this domain is the alignment of an organisations systems and technology strategy with its business objectives. The difficulty is the complex and diverse nature of the strategy process itself that renders such a match increasingly problematic. The evidence w...

Strategic Information Systems Security: Definition and Theoretical Model

Information systems security has become a critical topic both academically and in industry due to its importance in today’s organizational environment. But while its criticality is undeniable, information systems security continues to be viewed reactively, as a “necessary evil,” or, worse, as a black hole with little or no ROI.

Security as a theoretical attribute construct

This paper provides an overview of the field of security metrics and discusses results of a survey of security experts on the topic. It describes a new framework for developing security metrics that focuses on effectiveness measures while maintaining measures of correctness. It introduces a view of security as a theoretical concept which encapsulates multiple aspects of a system. Viewing securi...

Strategic Information Systems Planning Success: An Investigation of the Construct and Its Measurement

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
