Factors Affecting Performance

It is an accepted fact that no system is perfect from the viewpoint of performance. Problems pertaining to performance affect all types of systems, regardless as to whether they are client/server or Web application systems. It is imperative to understand the factors affecting performance of the system before embarking on the task of tackling them. The constraints affecting the performance may be many but can be broadly classified into (i) technical and (ii) project related factors. The former is very much pronounced in the case of Web-based systems, as the relevant technology has not attained the stage of maturity to address the issues on its own. On the other hand, the project managers struggle to develop an optimal system within the existing technology framework. This in turn, generates many project related factors sub optimizing the performance. Likewise, many factors affecting the performance of the system are discussed in this chapter. The subsequent chapters deal at length with the methods and strategies to tackle these factors.

Purpose The purpose of this study was to investigate the perceptions of construction professionals relative to factors that affect the delivery of optimum health and safety (H&S) on construction projects during the COVID-19 pandemic. Design/methodology/approach The study adopted a quantitative design which entailed the distribution of a web-based questionnaire among construction professionals, namely, architects, construction/project managers, engineers, H&S managers and quantity surveyors working for contractors and construction consultants in Zimbabwe. The data were analysed with descriptive and inferential statistics. Factor analysis was used to reveal interrelated significant sets of factors affecting the delivery of optimum H&S. Findings Factor analysis revealed nine components/factors: change and innovation-related, monitoring and enforcement-related, production-related, access to information and health service-related, on-site facilities and welfare-related, risk assessment and mitigation-related, job security and funding-related, cost-related and COVID-19 risk perception-related factors as the significant factors affecting the delivery of optimum H&S during the COVID-19 pandemic in Zimbabwe. Research limitations/implications The results highlighted the need for social dialogue among construction stakeholders to support initiatives that will enhance the delivery of H&S on construction projects. Construction stakeholders may find the results useful in highlighting the areas that need improvement to protect workers’ H&S during the pandemic. However, the small sample limits the generalisability of the results to construction sectors in other regions. Originality/value The study investigated factors affecting the delivery of optimum H&S during the COVID-19 to inform interventions to enhance H&S.

Abstract Objective: This study analyzes the clinical features and prognosis of stages Ⅰ-Ⅲ colon cancer, and constructs a nomogram to predict the prognosis of patients. Methods: We included data from patients with stages Ⅰ-Ⅲ colon cancer confirmed by pathology after surgical treatment in the United States SEER (Surveillance, Epidemiology, and End Results) database from 2010-2015. The included patients are randomly divided into training cohorts and validation cohorts (ratio 1:1).The independent related factors of the prognosis of colon cancer patients were used to construct the nomogram and the web-based probability calculator.Concordance index (C-index) and calibration curve are used to evaluate the accuracy of the model. Results: After univariate and multivariate analysis, it was indicated that age, marital status, tumor grade, t-stage and n-stage were independent factors affecting prognosis of patients with stages Ⅰ-Ⅲ colon cancer. We built a nomogram and the web-based probability calculator based on this, and its C-index was 0.781 (95% CI: 0.77414–0.78786), and were superior to that of AJCC TNM Stage (C-index: 0.734, 95%CI: 0.72616–0.74184). The consistency test showed that the nomogram can effectively predict the prognosis of patients. The validation cohort confirms the reliability of the model. Conclusion: Age, marital status, tumor grade, t-stage and n-stage are independent factors affecting the prognosis of patients with stages Ⅰ-Ⅲ colon cancer. The nomogram we constructed in this way can better predict the prognosis of patients with stages Ⅰ-Ⅲ colon cancer.

While web applications continue to employ traditional client-server model, most of the current applications demand real time bi-directional communication. In such setups, data exchanges between both the parties (client and server) are very frequent. Thus, performance of the network is subject to various factors decided by the choice of data exchange mechanism. This shows that the choice of data exchange mechanism is vital to performance of a web-application employing it. This paper compares various data exchange mechanisms with respect to factors affecting real time web applications. While the absolute values of benchmarking may vary with the systems, the relative difference between them can be used as a reference for selecting a mechanism for an application. Hence, this paper can be used as a reference to choose appropriate data exchange mechanism for the concerned application.

Gathering Data

The aim of our studies was to design a Metacognitive Questionnaire on Time (MQT) that assesses inter-individual variations in the awareness of factors affecting the experience of the passage of time. In the first study, 532 young adults were asked to reply to an initial questionnaire consisting of 106 questions relating to many different factors (e.g., psychostimulant, body temperature, age, attention) that could affect how time is perceived. Factorial analyses allowed us to extract two discriminant factors, one relating to attention and the other to emotion. The second study sought to validate the final 24-item questionnaire by gathering data from 212 university students. Confirmatory Factorial Analyses (AMOS) showed that the MQT has the same two-factor structure. The third study assessed the construct validity of the MQT by measuring the correlation between the MQT scores and the scores with other questionnaires measuring close or different constructs. In sum, these studies enabled us to develop an easy-to-use questionnaire whereby it is possible to distinguish between individuals according to their subjective feeling of the passage of time. In addition, the participants’ responses on the MQT showed that they were more aware of attention-related factors than of emotion-related factors that might produce time distortions, and that women were more aware of their own temporal distortions than men.

Olfactory Acuity

Mental activity in sleep often involves visual and auditory content. Chemosensory (olfactory and gustatory) experiences are less common and underexplored. The aim of the study was to identify olfaction-related factors that may affect the occurrence of chemosensory dream content. Specifically, we investigated the effects of all-night exposure to an ambient odour, participants’ appraisal of their current olfactory environment, their general propensity to notice odours and act on them (i.e., odour awareness), and their olfactory acuity. Sixty pre-screened healthy young adults underwent olfactory assessment, completed a measure of odour awareness, and spent three nights in weekly intervals in a sleep laboratory. The purpose of the first visit was to adapt to the experimental setting. On the second visit, half of them were exposed to the smell of vanillin or thioglycolic acid and the other half to an odourless control condition. On the third visit, they received control or stimulation in a balanced order. On each visit, data were collected twice: once from the first rapid eye movement (REM) stage that occurred after 3 a.m., and then shortly before getting up, usually from a non-REM stage. Participants were asked to report the presence of sensory dream content and to assess their current olfactory environment. Neither exposure, nor participants’ assessments of the ambient odour, or olfactory acuity affected reports of chemosensory dream content but they were more frequent in individuals with greater odour awareness. This finding may have implications for treatment when such experiences become unwanted or bothersome.
