Procurement System

The Procurement plan and procedure in Nigeria have gone through a number of changes, with main objective of reducing or at best eliminating corruption in public procurement, realizing values for money, efficiency in procurement process among others. The data of assessment of procurement plan in the Nigerian construction industry was collected through administrating questionnaire to selected members of the companies and was analyzed using three statistical tools, namely; percentage analysis, chi-square and measures of dispersion. The table from which was  drawn the  analysis of  assessment of procurement  plan in the Nigeria construction industry reveal that  among the professionals who responded to the questionnaire 27.6% are members of the Nigeria Institute of Quality Surveyors (NIQS) , 13.2% belong to the Nigeria Institute of Architects (NIA), and 22.4% belong to the Nigeria institute of Builders (NIOB), while 3.9% are members of Nigeria Society of Engineers (NSE), those who belong to other professional body other  than the those above are 9.2% and 23.7% are not registered with any professional body. From the chi-square test of independence, it was found that at 5% level of significance opinion of respondents is not independent of their professional background. The Likert summary table also show reveal the following (i) procurement system affect project cost (ii) procurement system affect quality of work (iii) procurement plans affect design team performance. Also, the statements with low variance and standard deviation are more reliable than those with high variance and standard deviation. Therefore, on commencement of construction projects consultant must advise their clients on the building procurement system available.

Abstract Background This study aimed to assess the level of trust in the COVID-19 risk communication efforts in Nigeria. Methods We conducted a descriptive cross-sectional study among community members aged 15 years and above in Ondo state in October, 2020. Data were collected using an interviewer-administered questionnaire. Data were analyzed using SPSS version 22. Descriptive statistics were summarized using frequencies. Trust was ranked from “1” implying “Low level of trust” to “7” denoting “High level of trust”. We conducted bivariate Chi-square test on respondents’ level of trust in the Nigeria Centre for Disease Control (NCDC) and socio-demographic characteristics. The level of significance was set at p<0.05. Results Among the 691 respondents, 244 (35.3%) were aged 21 to 29 years, and 304 (51.4%) used the NCDC to obtain COVID-19 knowledge. Overall, 205 (41.8%) had high level of trust in the NCDC. Furthermore, 51 (51.5%) individuals aged 30-39 years had high level of trust in the NCDC (ᵡ2=17.455, p= 0.001). Also, 114 (48.5%) persons who lived with children below 18 years had high level of trust in the NCDC (ᵡ2= 8.266, p= 0.004). Conclusion Policy makers should prioritize the involvement of young and educated persons in COVID-19 risk communication strategies.

Abstract Background The present study aimed to investigate the patients’ perception of the dental practice during the COVID-19 outbreak, and whether the pandemic will affect the attendance of orthodontic patients at the dental practice. An online questionnaire, including the Patient Health Questionnaire-4 (PHQ-4), was submitted to Italian dental patients with items about their perceived risks when going to the dentist, concerns about continuing orthodontic treatment, and the onset of temporomandibular disorders (TMD). Data were analyzed with a chi-square test and logistic regression analysis. The level of significance was set at P < 0.05. Results A total of 1566 subjects completed the survey, including 486 who were under orthodontic treatment or who had a child in orthodontic treatment. A total of 866 participants (55.3%) thought the risk of contracting the COVID-19 infection was higher in a dental practice; this perception was associated with gender (women more than man), age (over 60 years old) and high levels of distress (P<0.001). However, 894 patients (57.1%) felt comfortable going back to the dentist. Most of the orthodontic patients (84%) would continue their treatment. After the lockdown, there was a slight increase in the frequency of TMD pain (356 versus 334). Conclusions Most of the participants believed that the dental practice is a place at greater risk of contracting COVID-19, even if they continue to go to the dentist. Gender, age, and the level of distress were associated with the increase in the fear of going to the dentist due to COVID-19. Because of the pandemic, 16% of patients undergoing orthodontic treatment would not return to the dental practice to continue their orthodontic treatment after the lockdown. The prevalence of TMD pain in the population increased due to the pandemic.

Purpose The Nigerian construction industry is bedeviled with poor project performance and outcomes which value management (VM) could address if applied. The application of VM on Nigerian construction projects is very minimal due to certain obstacles, namely, lack of VM experts, paucity of knowledge on the techniques, etc., which inhibits the adoption into the construction industry. Therefore, this study aims to develop a conceptual framework of the adoption of VM on construction projects in a typical developing economy. Design/methodology/approach This study engaged 15 selected VM experts in two rounds of Delphi survey to develop a conceptual framework of VM adoption. The method of data analysis includes mean score, standard deviation, Kendall’s coefficient of concordance, chi-square (χ2) test, interrater agreement analysis and significant level analysis. The developed conceptual framework was sent to a team of local and international VM experts for validation. Findings This study reveals that the adoption of VM requires the collective effort of relevant stakeholders in the construction industry. The framework developed presents individual and collective activities to be undertaken by the stakeholders. The activities include training, legislation, government-funded research, etc. Thus, the adoption of innovative management methodology like VM requires the collaboration of academics, construction professional bodies and government parastatals. This will assist in the judicious use of limited construction resources and boost the relevance of the Nigerian construction industry among developing nations and in the global construction market. Originality/value This study used the opinions of few construction professionals that can be regarded as VM experts in Nigeria, as against engaging a pool of construction professionals who may not be knowledgeable in VM process. Engaging the few VM experts in the Nigerian construction industry is important to have a valid basis for drawing conclusion, as large questionnaire survey could be possibly filled by inexperienced or unqualified respondents if stringent criteria are not considered at the outset of this study.

This study investigated on classroom attentiveness of children from home with inter parental violence in Chamwino, Dodoma, Tanzania. The study employed the cross-sectional survey design whereby 312 out of 652 children from five secondary schools were randomly selected to participate by filling the questionnaire. Chi square test was employed to determine the relationship between violence against mothers and children’s attentiveness at the 0.05 level of significance. The results indicated a significant relationship between parental conflicts and lack of pupils’ adequate concentration in learning. The findings further showed that female children whose mothers are accustomed to violence are more inattentive than male children during the teaching and learning processes. The study recommends that effective intervention strategies such as developing training through psycho education within families, schools and the community be in place.

Saudi Arabia has had many issues in delivering mega construction projects, such as delays, high costs, and low customer satisfaction. Some studies show that around 70% of public projects in Saudi Arabia are delayed. One factor that might be causing these performance issues is the traditional low bid contracting system in Saudi Arabia, or the Saudi procurement system. In Saudi Arabia, owners select contractors based only upon the lowest price. This paper researched ways to modify the current Saudi procurement system and show quick and simple modifications that can be done to improve the low performance. This research proposes that by adding the clarification phase from the Performance Information Procurement System (PIPS) to the Saudi traditional procurement process could greatly improve construction performance. The clarification phase requires the selected contractor to submit a project scope, detailed and milestone schedule, potential risks that they do not control, and performance measurement before a contract is awarded. The PIPS system is one of the most successful systems around the world, which shows success rate of 98% in six different countries with risk and cost reduction up to 30%. The clarification phase has been identified as the most important step in the PIPS to ensuring a successful project. This paper conducted a survey among construction professionals in Saudi Arabia, including 157 engineers, 33 consultants 9 owners, 5 vendors, 13 academics, and 28 architects, in order to develop the public procurement system in Saudi Arabia. The participants work in government sectors with an interest in the Saudi Arabian procurement system. The survey confirmed that professionals in the Saudi construction industry believe that the procurement system should be changed and that the inclusion of the clarification phase to the procurement system is a way to improve the procurement system.

 This study presents an attitude of female students studying B.Ed. third year towards physical education and sports within Kathmandu valley. Initially, it was hypothesized that there is no significance difference in attitude of physical education and sports among female students of different campuses. From these 6 campuses, 184 female students were randomly selected. A five-point Likert-type scale was applied for data collection from the selected students who studied in B.Ed. third year. Altogether five opinion statements were used for data collection. It was found that all respondents showed positive attitudes towards physical education and sports. In order to test whether there is significant interdependence in score among the respondents in different perspectives. The chi-square test score was applied as statistical test at the 0.05 level of significance. The chi-test under contingency table: independent of opinion among the respondent, if (χ2>α=0.05 in different degree of freedom) and independent if (χ2≤ α=0.05 in different degree of freedom). For the measurement of attitude for physical education and sports,it has enough evidence in the data to accept alternatives hypothesis; there is relation or interdependence of attitude towards physical education and sports among the respondents. Because, the score is very high among the response of respondent. The study suggests that the university teacher must be accountable to construct professional environment.

Since the declaration of Malaysian independence, the public sector has significantly contributed to the country’s development. In the 1990s, a new procurement system was developed due to CIBD various changes in the construction industry. Since that period, the poor quality of public sector projects has started to attract public attention. This paper describes a study that was conducted to identify the dominant public procurement systems in place, the problems associated with these systems, and the satisfaction level of the industry players in the Malaysian construction industry. The results were drawn from 84 survey responses and interviews with industry players. The public sector is using a traditional system inherited from the British, with an intention to adopt new procurement systems. Aside from the disputes that are present in most systems, the public sector seems to encounter particular problems in relation to capabilities, time, and cost of the major procurement systems used. Traditional work culture and the industry environment influence public sector practice, which accounts for the modifications of each procurement system used. Thus, the full advantages of using an alternative procurement system may not be realised in public sector organizations. This produces an average level of satisfaction gained from the procurement system adopted. As a developing country, Malaysia needs to exert significant efforts to improve the public procurement system.

This study aimed to identify types and sites of body injury, location of injury occurrence, and the mechanism and severity of injuries in novice and advanced Brazilian jiu-jitsu (BJJ) athletes. One hundred and eight BJJ athletes took part in this study separated in two groups: advanced (n = 53) and novice (n = 55). Athletes answered a questionnaire concerning regions of injury, locality of occurrence, injury severity and mechanism. Chi square test and a logistic regression analysis were used with the level of significance set at p < 0.05. The main results showed that shoulders and knees were the most injury location reported by novice and advanced athletes. Novice athletes demonstrated higher prevalence of injuries during training sessions (54.5%), whereas advanced athletes reported more injuries during competitions (66.1%). Significant associations between novice and advanced athletes were observed for major joints (p < 0.05). The odds ratio of having injury was 70-87% less for novice versus advanced athletes for the major joints cited. We concluded that BJJ athletes demonstrate high prevalence of injury mainly at knee and shoulder. While risk of injury appeared less in novice, the advanced demonstrated higher number of injuries during competitions as a consequence of injured joint keys. By contrast, novice athletes reported higher number of injuries associated with training sessions as a consequence of overuse.
