The purpose of this study is to examine the risks of using statistical tools in a project basis. A systematic search of certain academic databases has been conducted for this study. Statistical tools could be used in a project, and they should be properly planned and designed. Statistical tools include major activities, such as collecting and analyzing data, providing meaningful interpretation, and reporting findings. When dealing with statistical tools, there are several risks that may exist and impact the project either positively or negatively. This study covers a brief outline of the risk management, statistical tools, and the relationship between the two concepts. Finally, a discussion of the common type of risks that are initiated by using statistical analysis tools are provided, which could be planned, identified, and analyzed in the early stages of the project.

Over Time

Projects are very important to all organizations, as project managers view various issues in the organization from a higher perspective. The conclusions drawn from these projects determine the base on which various decisions affecting the organizations will be made. This paper introduces the statistical analysis tools used in various project environments to differentiate between the effective and ineffective tools of statistical analysis. Statistical analysis tools are useful in analyzing data collected for a study to be conducted on the same data. The literature review illustrates how statistical analysis tools have been effective and useful to researchers. Over time, more effective statistical tools will be invented that will improve the process of data analysis. The findings on different statistical analysis tools will also be highlighted. Thus, the discussions show the impact, applications, and lessons learned from the statistical analysis tools by the project managers and engineers. The study will also present the limitations, along with the conclusions and recommendations.

The Relationship

The term ‘risk management’ implies that risk is something which can be quantified, predicted and controlled. This paper seeks to demonstrate the limits of this assumption where complex projects are involved. The argument is based upon a case study of a failed £80 million IT venture known as Taurus. Analysis focuses upon the relationship between politics and the assumption of risk. Acceptance of risk, it is argued, is ultimately determined by the balance of power between decision makers. Moreover, risk analysis and other techniques of management may actually compound the difficulties by fostering an illusion of control and escalation. The implications for project management are discussed.

The Relationship

The aim of the study is to assess the relationship between project management (PM) practices and project success (PS) criteria in engineering firms in Kuwait. As a first step, a comprehensive literature review followed by interviews with CEOs from 10 selected firms and consultations with three experts were conducted to design the research framework. As a result, a research model that consists of PM practices measured by six dimensions (leadership, IT, teamwork, planning, governance, and communication) and PS criteria measured by three dimensions (impact on customers, impact on project team, and business success) were instilled. Based on statistical analysis on the survey responses, it was found that communication and teamwork are the strongest predictors for PS criteria, and other PM dimensions were perceived to be less important. This result is encouraging and comforting as it shows that the team-oriented factors are perceived to be important in the success of projects and implies that having a cohesive team is crucial for managing successful projects.

The Relationship

In this research, the concept of Duration with a new application in project management has been defined. The Duration of each project provides the project manager with a combined measure containing concepts of return, cost and time of the project. Further in this article, the changes in project return, based on different assumptions such as discount rate, have been examined. To examine the effect of the changes in these factors, the Monte Carlo simulation has been used. The relationship between these factors is nonlinear which reflects the great importance of investment on appropriate risk management systems. The data from a set of construction projects have been used in order to verify the results of this study. Similar relationships can be expected to exist in other industries as well.

Nova Outburst

We have evolved a large number of models of thermonuclear runaways in the hydrogen-rich envelopes of 1.00 M⊙ carbon-oxygen white dwarfs. Models characterized by enhanced CNO abundances satisfy the observations of the common nova outburst. They eject from 1027 to 1029 g moving with velocities of 200–2400 km s−1: kinetic energies of 1044 to 1045 erg. The theoretical light curves are similar to the observed light curves of common novae during the early stages of the outburst. As a consequence of our studies, we can present an explanation for the continuous ejection of mass which is observed for long times after the initial outburst and for the relationship between maximum magnitude and the decline to minimum. We are also now able to present an explanation for the constant luminosity phase of the outburst and the oval shapes of the ejected nebulae.We have extended our earlier work to models with extreme enhancements of 12C and to models which include the infalling material in the evolution. The extreme 12C studies result in outbursts which reach near supernova proportions while the accretion models result in light curves which resemble observed light curves quite closely. Finally, the accretion studies also demonstrate the need for enhanced abundances.

Malignant syphilis is a rare skin manifestation of secondary syphilis, which has been reported primarily in the HIV-infected population. This study aimed to investigate the relationship between HIV infection, malignant syphilis, and neurosyphilis through a systematic chart review of 26 malignant syphilis patients seen at our hospital. We also performed a literature review of 83 reported malignant syphilis cases since 1987, when the first case of malignant syphilis co-infected with HIV was reported. We found there was no direct association between HIV infection and malignant syphilis or neurosyphilis. In contrast, we found that much higher proportion (30%) of malignant syphilis patients develop concurrent neurosyphilis compared to those with the common type of secondary syphilis (13.1%). Physicians should be aware of the fact that neurosyphilis is more common among patients with malignant syphilis and the importance of investigating for neurosyphilis in such patients.

The study aims to investigate the effectiveness and ineffectiveness of different statistical analysis tools in project management environments. Furthermore, this study focuses on identifying some factors that affect project management by highlighting some commonly used statistical analysis tools and by evaluating ineffective analysis tools. Quantitative data was collected through participant observation, as well as a review of the relevant materials to meet these objectives. Some of the dependent variables that were tested in the study include the project manager's skills, the organization's financial status, and the affordability of the analysis tools. The independent variable is the effectiveness and ineffectiveness of the statistical analysis tools. After collecting and analyzing the data, the study finds that a tool's effectiveness or ineffectiveness depends on the dependent variables, i.e., the project managers' skills, the organization's financial status, etc.

Obviously the use of Information Communication Technology (ICT) by organizations is increasing over the years, whether in government or the private sector. The use of ICT can be seen to increase efficiency and effectiveness of the services or products offered. To meet the demand of stakeholders today, ICT projects need to be developed through outsourcing. However the method of outsourcing has some issues that can affect the success of the development of ICT projects as has been much debated by previous studies. Yet, the discussion on project management success (PMS) factors that concentrate on the competency measurement for the department's officers who are managing the procurement process has not been sufficiently clarified. The aim of this Systematic Literature Review (SLR) is to identify the common attributes that influence project management success through the procurement procedure carried out by the procurement officer (PO). The outcome of the review explained the important relationship pattern between the identified attributes which will be applied in the future empirical and exploratory survey that will be carried out. Addition to this, the competency measurement model of ICT procurement officer to be developed.

Background The COVID-19 outbreak has forced teachers to transition to online teaching, requiring them to adapt their courses and pedagogical methods to an online format rapidly without relevant training. This has presented a formidable challenge to higher education teachers. The present study uses a person-centered approach to identify heterogeneity among higher education teachers’ affective experiences and the relationship between this heterogeneity and their psychological adjustment to online teaching. Methods In total, 2,104 teachers in higher education institutions in Southern China were surveyed using the Positive and Negative Affect Schedule and the Psychological Adjustment to Online Teaching Scale (a measure developed for this study) between March 25 and March 31, 2020. The collected data were analyzed using latent profile analysis. Results Based on their affective experiences during online teaching immediately after the COVID-19 outbreak, higher education teachers were divided into three latent classes: the common, ambivalent, and positive types. Among them, the positive type accounted for the largest proportion (44.85%), while the ambivalent type accounted for the smallest proportion (23.93%). The rest was the common type, which accounted for 31.15%. Significant differences in psychological adjustment to online teaching were found between the three latent classes. Regarding positive psychological adjustment, teachers belonging to the ambivalent type had significantly lower scores than those belonging to the other two types. Further, the common type had a significantly lower score than the positive type. Regarding negative psychological adjustment, the ambivalent type had a significantly higher score than the other two types, and the common type had a significantly higher score than the positive type. Conclusion Based on a novel person-centered perspective, this study revealed the differences and complexity in higher education teachers’ affective experiences of online teaching immediately after the COVID-19 outbreak. The three different types of affective experiences (common, ambivalent, and positive) had a significant influence on psychological adjustment, with teachers belonging to the ambivalent type showing the worst psychological adjustment. This study provides a new perspective for the discussion of the relationship between teachers’ affective experiences and their psychological adjustment to online teaching.

Widespread Interest

The common widespread interest in the socio-cultural aspect of language learning among applied linguists has made ESL researchers draw attention to learners' motivation and autonomy in the European and Asian educational circles. The rationale of this study is to pinpoint the relationship between EFL learners’ motivation and autonomy. To gather relevant data, motivation and autonomy questionnaires were distributed among 100 EFL learners, who were chosen through Quick Placement Test (QPT), and were put them into B2, C1, and C2 levels of linguistic proficiency based on Common European Framework Rubric (CEFR) model. To fulfill the objectives of this study, both descriptive and inferential statistics were utilized in the process of data analysis. Regarding the statistical analysis, learners’ motivation significantly correlated with their autonomy. Additionally, it was found that there was a significant positive correlation between autonomy and intrinsic motivation, while the correlation between autonomy and extrinsic motivation was significant but negative. This study can shine a light on language teaching in general and in particular on the relationship between EFL learners' motivation and autonomy.
