The Organizational Culture of Gaza Strip Construction Companies

Organizational culture gives identity to an organization. Nowadays with the increasing of the internationalization of the construction industry, the organizational culture become more importance than any other times. The aim of this research is to investigate the organizational cultural profile of the Gaza Strip construction organizations, this aim was achieved by investigating the importance of the organizational culture, identifying the current organizational cultural type of the Gaza Strip construction organizations, and identifying the desired organizational cultural type of the Gaza Strip construction organizations. The study used a questionnaire that was administered by contracting companies classified at the Palestinian Contractors Union. Out of 134 questionnaires were distributed, only 74 questionnaires were received. The results of the organizational culture profile present that the dominant current and the desired organizational culture was clan culture type for all Gaza Strip construction organizations. Also results showed that the organizational culture affected by changing the organizations size. The results showed that the very small organizations had hierarchy type as the dominant current culture and preferred to be clan type as the dominant desired culture, it showed also that the small organizations had a market type as the dominant current and desired organizational culture, it presented also that the clan culture type was the dominant current and desired organizational culture medium organizations, it showed that the large organizations had clan type as the dominant current culture and preferred to be market type as the dominant desired culture

Importance of Organizational Culture for Gaza Strip Construction Companies

Despite of different definitions of organizational culture, shared meanings, assumptions, beliefs and understandings held by a team are considered as the basic component of the organizational culture definition. Organizational culture gives identity to an organization. Nowadays with the increasing of the internationalization of the construction industry, the organizational culture become more importance than any other times. The aim of this research is to investigate the importance of the organizational culture for Gaza Strip construction companies. The study used a questionnaire that was administered by contracting companies classified at the Palestinian Contractors Union. Out of 134 questionnaires were distributed, only 74 questionnaires were received. The research found out that the existence of the organizational cultural in the organization is very important for its survival and continuity, where the organizational cultural help in achieving the organization goals, the organizational cultural help the organization to take right actions and decisions, the organizational cultural help in creating policies and assignments to increase profitability, growth, and respond to market demands, the organizational cultural help the individuals and teams to do the assigned work efficiently, and the organizational cultural play basic role in sharing of information rapidly inside the organization

Bonding Strength between Geopolymer Fly Ash to Ordinary Portland Cement Concretes using Mohr-Coulomb Theory

This paper presents an experimental study to analyse the bonding strength between geopolymer concrete (GC) and normal concrete (NC) bond substrate. Three different strengths of GC which were 80 MPa, 85 MPa and 90 MPa were bonded to 30 MPa NC and denoted as NC30-GC80, NC30-GC85 and NC30-GC90. Slant shear and split tensile tests were conducted to investigate the bonding strength between two different substrates. The effect of bonding was then determined by using Mohr-Coulomb theory where critical bonding condition (smooth surface) was created. From the analysis, it was found that NC30-GC80 had the most powerful self-adhesion between GC towards NC. This result indicated the highest bonding strength of GC to NC at critical condition. Such strong bond was obtained by the effect of self-adhesive from GC to NC. The self-adhesive characteristic which represented by pure shear strength was obtained from Mohr-Coulomb theory

Elective Cancer Surgery in COVID-19-Free Surgical Pathways During the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study.

PURPOSE: As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19-free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS: This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19-free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS: Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19-free surgical pathways. Patients who underwent surgery within COVID-19-free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19-free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score-matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19-free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION: Within available resources, dedicated COVID-19-free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Preoperative nasopharyngeal swab testing and postoperative pulmonary complications in patients undergoing elective surgery during the SARS-CoV-2 pandemic.

BACKGROUND: Surgical services are preparing to scale up in areas affected by COVID-19. This study aimed to evaluate the association between preoperative SARS-CoV-2 testing and postoperative pulmonary complications in patients undergoing elective cancer surgery. METHODS: This international cohort study included adult patients undergoing elective surgery for cancer in areas affected by SARS-CoV-2 up to 19 April 2020. Patients suspected of SARS-CoV-2 infection before operation were excluded. The primary outcome measure was postoperative pulmonary complications at 30 days after surgery. Preoperative testing strategies were adjusted for confounding using mixed-effects models. RESULTS: Of 8784 patients (432 hospitals, 53 countries), 2303 patients (26.2 per cent) underwent preoperative testing: 1458 (16.6 per cent) had a swab test, 521 (5.9 per cent) CT only, and 324 (3.7 per cent) swab and CT. Pulmonary complications occurred in 3.9 per cent, whereas SARS-CoV-2 infection was confirmed in 2.6 per cent. After risk adjustment, having at least one negative preoperative nasopharyngeal swab test (adjusted odds ratio 0.68, 95 per cent confidence interval 0.68 to 0.98; P = 0.040) was associated with a lower rate of pulmonary complications. Swab testing was beneficial before major surgery and in areas with a high 14-day SARS-CoV-2 case notification rate, but not before minor surgery or in low-risk areas. To prevent one pulmonary complication, the number needed to swab test before major or minor surgery was 18 and 48 respectively in high-risk areas, and 73 and 387 in low-risk areas. CONCLUSION: Preoperative nasopharyngeal swab testing was beneficial before major surgery and in high SARS-CoV-2 risk areas. There was no proven benefit of swab testing before minor surgery in low-risk areas
