Entrepreneurship is an important part of any economy today regardless of its level of development. However, not in all contexts do entrepreneurs operate in the same way, nor are they motivated by the same factors. This research seeks to identify possible coincidence factors and differences between entrepreneurs that operate in different contexts from the point of view of their historical evolution, the duration of these and the economic and social model applied in the countries. Specifically, a comparative study is carried out between entrepreneurs from the republics of Ecuador and Cuba considering various variables such as: personality characteristics (attitude to failure, risk, perseverance and innovation), use of the available time fund for work in entrepreneurship; Impact of the environment in relation to: government regulations, taxes, level of competition and availability of suppliers, as well as the structure of personal expenses projected in the short and long term that entrepreneurs assume as a stimulus for their actions. For the development of the study, a description of the behavior of the variables was initially made and later, by hypothesis testing, to verify differences and similarities between both populations. The study allowed us to identify common and divergent aspects between both populations analyzed. Similarly, it showed how differences in the administrative and financial environment in which entrepreneurs operate generate changes in their priorities and projections.

This paper presents findings of a comparative study on the removal and disposal of fenestration units in two separate buildings, belonging to the same period and built with similar construction materials. Demolition techniques were used for removing the fenestration units from a building that was undergoing refurbishment; while, deconstruction techniques were used for dismantling similar units from another building that was being selectively demolished. It was concluded that the amount of energy consumed, time taken and waste generated, were far greater, and the revenues much lower, when conventional demolition techniques and tools were used. Hence, from the point of view of resource conservation (material, energy, time, and money) deconstruction was found to be more advantageous in the disposal of reusable building components.

The objective of the research was to evaluate the performance of the teaching staff of the Baghdad and Salahaddin University-Erbil from the point of view of the heads of their departments in a number of different colleges as a comparative study. The research community was (247) individuals from the heads of departments in the above universities, and a sample size was chosen randomly was(197) unit, and (134) individuals from the department heads at the University of Baghdad, and (63) unit from the department heads at Salahaddin University-Erbil. To achieve the research objectives, a (closed — open) questionnaire was prepared consisting of (49) paragraphs distributed into six specific fields of alternatives. To answer it and one open question in the questionnaire, the validity and reliability of the questionnaire was verified. The data was analyzed using the (weighted mean equation, the percentage weight equation and the chi-square test). The results showed there was no differences between the responses of department heads in evaluating the teaching performance of faculty members in the research sample in two universities. In addition, a number of proposals were presented to develop the performance of faculty members from the point of view of department heads in both universities. The two researchers made a number of recommendations as well, as well as a number of proposals to conduct future research for researchers in this field.

Object Oriented Metrics

This chapter presents the analysis of ten recently proposed object-oriented metrics based on cognitive informatics. The metrics based on cognitive informatics use cognitive weight. Cognitive weight is the representation of the understandability of the piece of software that evaluates the difficulty experienced in comprehending and/or performing the piece of software. Development of metrics based on Cognitive Informatics (CI) is a new area of research, and from this point of view, for the analysis of these metrics, it is important to know their acceptability from other existing evaluation and validation criteria. This chapter presents a critical review on existing object-oriented cognitive complexity measures. In addition, a comparative study based on some selected attributes is presented.
