The main aim of this paper is to identify critical success factors (CSFs) and investigate whether they are the same or not across different project organization structures. The organization structures under the study are: functional, project, and matrix. The study is based on a survey that was conducted on a large number of software projects in Jordan. To rank success factors (SFs) and identify critical ones, we use the importance index of SFs, which is calculated based on the likelihood and impact across different structures. For deeper analysis, we carry out statistical experiments with an ANOVA test and Spearman’s rank correlation test. Analysis results of an ANOVA test partially indicates that the values of the SF importance index are slightly different across the three organization structures. Moreover, the Spearman’s rank correlation test results show a high degree of correlation of the SF importance index between the function and project organization structures and a low degree of correlation between the function and matrix organization structures.

A great emphasis has taken place to identify and analyse the factors that have been af­fecting the success and the failure of construction projects in recent decades. As a project-based industry, construction has heavily invested in such research. Moreover, the construction industry suffers the most to meet deadlines and budgets limits. The objective of this paper is to identify the critical success factors in construction industry. The study focused on Middle East region. In order to achieve this objective, 25 project success factors were identified by reviewing related literature. The factors were assessed for their impact and contribution to the actual performance of the project on three criteria: schedule, cost, and quality. Then a questionnaire was developed and sent to dif­ferent experts in the construction industry. The collected data of 111 responses was then analysed statistically by using different tools such as: importance index, Spearman’s rank correlation factor and T-test. As a result, company’s technical capacity and scope and work definition were ranked the most important factors. The results of this research may provide a great assistance to professionals and researchers in identifying the critical factors in the construction industry.

Project Delay

This Meta-Analysis has examined the past ten years' studies concerning the causes of construction project delay. It aims to update the subject area and investigate critical causes of project delay in three different conditions of the external environment. The data from 50 studies have been analyzed and synthesized to determine the top ten critical causes of delay. The Relative Importance Index (RII) technique was applied to rank the critical causes; subsequently, the Spearman's Rank correlation coefficient was calculated to evaluate the critical causes. The review findings indicate substantial differences between the critical causes of project delay in defined situations. The top ten critical causes of delay in developed countries root in the project's internal environment. The leading causes of delays in developing countries are from the project's internal and task environment.

The article presents research on the local property tax policy of rural and urban-rural municipalities in Poland. Various methods were used to investigate the data interdependencies of mathematical statistics (Pearson’s correlation test, Spearman’s correlation test and Pearson’s independence test). For direct data and coefficients, Pearson’s classic correlation was used. With regard to the processed, dichotomic and enumerated data (including the contingency tables), Spearman’s rank correlation was used. The study showed that the tax policy of the analysed municipalities was differentiated and could, under certain conditions, give rise to a positive upward tendency of incomes generated in property tax – which should be seen as an original contribution of work from the authors of this article.

Persistent Thrombocytopenia

Background: Sepsis is defined as life-threatening organ dysfunction caused by dysregulated host responses to infection. Recent studies have suggested that endotheliopathy may be the common basis for multiple organ failure in sepsis. Under septic conditions, accumulation of proteases accelerates shedding of proteoglycans, such as syndecan-1, from the endothelial surface, resulting in augmented leukocyte adhesion to the vascular wall, enhanced vascular permeability, and intravascular coagulation. The purpose of this study was to determine the potential utility of syndecan-1 as a biomarker linking endotheliopathy to organ failure.Methods: One hundred patients with suspected infections who were admitted to the intensive care unit (ICU) at Kagoshima University Hospital were consecutively enrolled in the study. Serum syndecan-1 levels were measured using an in-house enzyme-linked immunosorbent assay. The difference between serum syndecan-1 levels in 28-day survivors and non-survivors was analyzed by the Mann–Whitney U-test. Receiver-operating characteristics curve analysis with area under the curve calculation was used to quantify the predictive performance of serum syndecan-1 for 28-day mortality. The correlations between serum syndecan-1 and coagulation markers were analyzed by Spearman's rank correlation test.Results: Serum syndecan-1 levels in non-survivors were significantly higher than those in survivors on Day 1 and Day 3 (P < 0.01). Among multiple organ failures, coagulation failure and renal failure were significantly correlated with serum syndecan-1. Spearman's rank correlation test indicated that serum syndecan-1 was weakly but significantly correlated with disseminated intravascular coagulation score (rho = 0.33, P < 0.01). Patients with serum syndecan-1 ≥21.4 ng/mL showed delayed recovery from thrombocytopenia relative to patients with serum syndecan-1 <21.4 ng/mL.Conclusions: Elevated circulating syndecan-1 on the first day of ICU admission was associated with persistent thrombocytopenia and lethal outcome in patients with suspected sepsis.

<p>Ostracod assemblages from Lake Trasimeno (Umbria, central Italy), the largest endorheic lake in Italy, were investigated relating their species distribution and ecology to modern physical, chemical and biological parameters. Nineteen living species were collected in the lake<em> </em>(<em>Darwinula stevensoni, Candona (Candona) candida, Candona (Neglecandona) angulata, Fabaeformiscandona fabaeformis, Pseudocandona marchica, Cypria ophtalmica, Ilyocypris gibba, I. salebrosa, I. getica, Cypridopsis vidua, Eucypris virens, Trajancypris clavata, Herpetocypris helenae, Heterocypris salina, H. incongruens, Isocypris beauchampi, Cyprideis torosa, Limnocythere inopinata, </em>and<em> </em><em>L. stationis</em>)<em>. </em>All the identified species belong to the fresh-water Italian ostracod fauna but<em> </em><em>Cyprideis</em> <em>torosa </em>is documented in an oligohaline athalassic lacustrine environment in Italy for the first time.<em> </em>The occurrence of<em> </em><em>Ilyocypris</em> <em>salebrosa </em>represents the southernmost record in Italy and the westernmost in Eurasia. The recovery of<em> </em><em>Limnocythere</em> <em>stationis</em> represents the westernmost record in Eurasia. The distribution of the different ostracods recovered in Lake Trasimeno is linked to the dominant physical and chemical parameters for each ecological niche. Physical and chemical data along with substratum type, grain-size and presence of aquatic macrophytes have been related to different ostracods using a multivariate analyses approach (NMDS, CCA, Spearman’s rank correlation test). These results allow to differentiate several ecological niches within the lake and indicate that the main parameters affecting the ostracod assemblages are the aquatic macrophyte coverage, the Total Organic Carbon (TOC) and, to a lesser extent, temperature and type of substrate.<em> </em><em>Cyprideis</em> <em>torosa </em>and<em> </em><em>Candona </em>(<em>Neglecandona</em>)<em> </em><em>angulata </em>have been recovered both in the distal part of the lake and in the lakeshore area. In both cases they are associated with scarce or absent aquatic macrophytes and low amounts of TOC. The<em> </em>alternate dominance of these two species in the distal deeper assemblages seems to be mainly linked with the bottom oxygen availability, being<em> </em><em>C.(N.) angulata </em>dominant in the most oxygen-depleted sediments and<em> </em><em>C. torosa </em>dominant in higher oxygen conditions.<em> </em>Along the lakeshore area they are often discovered together with other prevailing species, such as<em> </em><em>Cypridopsis</em> <em>vidua </em>that is common in very shallow to shallow<em> </em>(20-140 cm) sites with high TOC content, abundant macrophytes and algae, and Limnocythere inopinata, which dominates slightly deeper areas (around 150-210 cm) where the previous species are almost absent. The Spearman’s rank correlation test showed significant positive correlation between some ostracods and macrophyte species.</p>

Each child has a different ability to adapt. Some children experience the late process of social adaptation during preschool age. Therefore, this research was purposed to find out the correlation between parenting pattern and social adaptation development in preschool children studying at RA Muslimat NU 202 Assa’adah Sukowati, Bungah, Gresik.  The type of research was analytic done by applying cohort retrospective design. The population involved all parents and their children studying at the school mentioned above, totally 40 people, in which 36 respondents were taken as the samples by using probability sampling, namely simple random sampling technique. Questionnaires and observational sheets were used to collect the data, which were then analyzed by using Spearman’s Rank correlation test with the significance level of 0.05.  The result of research showed that most of the respondents (55.6%) applied democrative, whereas nearly all of the children (80%) had a good social adaptation development. Moreover, the result of correlation test showed that p = (0.000) < α (0.05) so that H0 was rejected illustrating that there was a correlation between parenting pattern and social adaptation development in preschool children studying at RA Muslimat NU 202 Assa’adah Sukowati, Bungah, Gresik.  The research concluded that the parents applying democratic parenting pattern resulted in a good social adaptation development in their children. Thus, they should apply the correct parenting pattern according to the age of their children.

Background and Aim: Uropathogenic Escherichia coli (UPEC) is commonly involved in urinary tract infections (UTIs), which are generally treated with antibiotics. However, the emergence of multidrug-resistant (MDR) strains of UPEC has made the treatment difficult. There is thus a need to continuously assess their sensitivity to antibiotics. This study aimed to determine the antibiotic resistance patterns and MDR phenotypes of UPEC strains isolated from children diagnosed with UTIs at the Russian Children's Clinical Hospital in Moscow, Russia. Materials and Methods: Kirby–Bauer's disc diffusion method was used to study the sensitivity to antibiotics of 106 UPEC isolates from urine specimens from children (aged from 9 months to 18 years old) diagnosed with UTIs. The results were interpreted in accordance with the Clinical and Laboratory Standards Institute guidelines and the correlations of variables with the degree to which each antibiotic inhibited the UPEC strains in terms of diameter on the disc were determined using Spearman's rank correlation test. A t-test and principal component analysis were performed to visualize the correlations of the susceptibility of UPEC to antibiotics with the age and sex of the patients. Statistical significance was set at p≤0.05. Results: Among the 106 UPEC strains tested, none (0%) showed resistance to fosfomycin (FO), while 84 (79.2%) were resistant (R) to at least one antibiotic. The highest rates of resistance were observed to amoxicillin (69.8%), ampicillin (62.3%), cefazolin (39.6%), trimethoprim (TR) (37.7%), ceftriaxone (34.9%), and tetracycline (33.0%). Interestingly, 22 (20.8%) strains were R to imipenem. UPEC isolates from males aged 1-6 years were more R to antibiotics than those from the other groups, with the exception of TR, to which UPEC isolates from females aged 13-18 years old were less sensitive (S). The multidrug-resistance (MDR) index ranged between 0.00 and 0.75 and we found that more than a quarter of UPEC (31/106) had an MDR index ≥0.5 and only 22 (20.7%) strains were S to all antibiotics tested (MDR index=0). Finally, Spearman's rank correlation test showed that, with the exception of FO, there were correlations between the inhibition diameters of all other antibiotics. Conclusion: FO is the only antibiotic to which all UPECs were S and may be suggested as the first line of treatment for UPEC. Further research is needed to continue monitoring antibiotic resistance and to investigate the genetic features associated with such resistance observed in this study.

Studies have shown that site sanitation practices are capable of improving the health and safety (H&S) performance of construction companies. In spite of this, evidence has shown that the level of compliance to these practices by construction firms is still poor. This study evaluated the effect of site sanitation on the safety performance of workers on construction sites. Data were obtained through a well-structured questionnaire. Analysis of data was done using Relative Importance Index (RII), Mean Item Score (MIS) and Spearman’s Rank Correlation. It was found that provision of first aid facilities is the measure most complied with on sites (RII = 0.96); relationship between level of compliance to good sanitation measures and accident rate is not significant; and provision of Personal Protective Equipment is the most effective strategy for minimising rate of accidents (MIS = 4.95). It was concluded that the effect of site sanitation on safety performance of workers on construction sites in Minna is not significant. It was thus recommended that construction firms should always comply with the measures for enhancing good sanitation on sites, especially “Provision of drinking water”, in order to improve safety performance on site.
