Thank you for reading experimental and quasi experimental designs for research. Maybe you have knowledge that, people have search numerous times for their favorite readings like this experimental and quasi experimental designs for research, but end up in malicious downloads. Rather than reading a good book with a cup of tea in the afternoon, instead they cope with some infectious virus inside their laptop.

Context: DevOps, the combination of Development and Operations, is a new way of thinking in the software engineering domain that recently received much attention. Given that DevOps is a new term and novel concept recently introduced, no common understanding of what it entails has been achieved yet. Consequently, definitions of DevOps often only represent a part that is relevant to the concept.Objective:This study aims to characterize DevOps by exploring central components of DevOps definitions reported in the literature, specifying practices explicitly proposed for DevOps and investigating the similarities and differences between DevOps and other existing methods in software engineering.Method: A systematic mapping study was conducted that used six electronic databases: IEEE, ACM, Inspec, Scopus, Wiley Online Library and Web of Science.Result: 44 studies have been selected that report a definition of DevOps, 15 studies explicitly stating DevOps practices, and 15 studies stating how DevOps is related to other existing methods. Papers in some cases stated a combination of a definition, practices, and relations to other methods, the total number of primary studies was 49.Conclusion: We proposed a definition for DevOps which may overcome inconsistencies over the various existing definitions of individual research studies. In addition, the practices explicitly proposed for DevOps have been presented as well as the relation to other software development methods.

What is DevOps?: A Systematic Mapping Study on Definitions and Practices

The Power of Habit: Why We Do What We Do in Life and Business

Since 2009, DevOps, the combination of development and operation, has been adopted within organizations in industry, such as Netflix, Flickr, and Fotopedia. Configuration management tools have been used to support DevOps. However, in this paper we investigate which Knowledge, Skills, and Abilities (KSA) have been employed in developing and deploying modern web applications and how these KSAs support DevOps. By applying a qualitative analysis approach, namely grounded theory, to three web application development projects, we discover that the KSAs for both Software Development and IT Operator practitioners support the four perspectives of DevOps: collaboration culture, automation, measurement, and sharing.

Cyber security researchers are starting to experiment with fear appeals, with a wide variety of designs and reported efficaciousness. This makes it hard to derive recommendations for designing and deploying these interventions. We thus reviewed the wider fear appeal literature to arrive at a set of guidelines to assist cyber security researchers. Our review revealed a degree of dissent about whether or not fear appeals are indeed helpful and advisable. Our review also revealed a wide range of fear appeal experimental designs, in both cyber and other domains, which confirms the need for some standardized guidelines to inform practice in this respect. We propose a protocol for carrying out fear appeal experiments, and we review a sample of cyber security fear appeal studies, via this lens, to provide a snapshot of the current state of play. We hope the proposed experimental protocol will prove helpful to those who wish to engage in future cyber security fear appeal research.

Cyber security fear appeals: unexpectedly complicated

Insider threats remain a significant problem within organizations, especially as industries that rely on technology continue to grow. Traditionally, research has been focused on the malicious insider; someone that intentionally seeks to perform a malicious act against the organization that trusts him or her. While this research is important, more commonly organizations are the victims of non-malicious insiders. These are trusted employees that are not seeking to cause harm to their employer; rather, they misuse systems-either intentional or unintentionally-that results in some harm to the organization. In this paper, we look at both by developing and validating instruments to measure the behavior and circumstances of a malicious insider versus a non-malicious insider. We found that in many respects their psychological profiles are very similar. The results are also consistent with other research on the malicious insider from a personality standpoint. We expand this and also find that trait negative affect, both its higher order dimension and the lower order dimensions, are highly correlated with insider threat behavior and circumstances. This paper makes four significant contributions: 1) Development and validation of survey instruments designed to measure the insider threat; 2) Comparison of the malicious insider with the non-malicious insider; 3) Inclusion of trait affect as part of the psychological profile of an insider; 4) Inclusion of a measure for financial well-being, and 5) The successful use of survey research to examine the insider threat problem.

Curiosity Killed the Organization: A Psychological Comparison between Malicious and Non-Malicious Insiders and the Insider Threat

In this paper, we describe the development and validation of three survey instruments designed to measure the human factor in information security and privacy. These instruments are intended to measure the extent to which people engage in the responses necessary to mitigate three different information security and privacy threats: computer performance compromise, personal information compromise, and loss of data and files. This paper makes a significant contribution by providing validated survey instruments that can be used by other researchers in the future. The instruments may be used in combination with various theoretical approaches, such as Protection Motivation Theory. Likewise, researchers may opt to use one, two, or all three survey instruments, depending on the particular needs of the research question(s) being addressed. Response pattern statistics are also provided along with suggestions for how the instruments may be used.
