Developing a Diamond Framework Model Based on “Integration” of Project Success Measures for Construction Project Management in Yemen

The most prominent obstacle facing the construction industry in Yemen is mismanagement. Developing appropriate tools, approaches, and standards for managing construction projects will contribute effectively to the development and prosperity of the Yemeni construction industry. This study aims to provide the tools, approaches and standards for project management based on the opinions of the Yemeni advisory bodies. It presents an Integrated Cost, Quality, Time, and Scope (ICQTS) diamond framework model by developing the traditional triangle model in project management providing a practical contribution to researchers and companies working in the construction industry. The study uses a descriptive and analytical approach through a comprehensive literature review followed by a field study using a designed questionnaire distributed to the relevant Yemeni advisory bodies. The study concluded with the development of the traditional triangle model resulting in the introduction of the diamond framework model in the management of construction projects. Integration management was found to have a strong impact on project success presenting the framework model as an easy and flexible tool that unifies and integrates the processes and roles in the project and directing it towards achieving project stakeholder objectives. The literature largely neglects the impact of integration management in the various models and is mostly overlooked. Inclusion of integration management in the presented model will highlight measures of project success stressing the need to integrate and manage them together. Future studies may research the differences in the opinions of construction companies.
Active ageing in Europe: are changes in social capital associated with engagement, initiation and maintenance of activity in later life?

Abstract The demographic landscape of European countries is rapidly changing because of population ageing; in this context, societies are called to offer older people opportunities to age actively. Although ‘active ageing’ has been broadly explored, there is still room to further our knowledge on the individual conditions that may favour or hinder activity in later life. This study aims to contribute to the literature in this field by focusing on the role of social capital. Specifically, it explores, through logistic regression models, how social capital and changes in social capital are associated with engagement in, the initiation of and continued participation in various domains of activity: volunteering and charity work, active participation in political or community-related organisations, informal care-giving and paid work. The data analysed stem from the Survey of Health, Ageing and Retirement in Europe (SHARE). We focused on people aged 55+ participating in Waves 4–6. The key findings are: (a) having a larger social network is positively associated with participation in and the initiation of activities; (b) receiving social support (rarely) may stimulate reciprocity and thus care-giving; and (c) an increase in social network size is positively associated with initiation and maintenance of activities during later life.
Studying the Impact of Leadership Style on Organizational Culture in New Agencies Under the Ministry of Culture and Islamic Guidance

Purpose: The performance of an organization’s members and its results root in an ethical organizational culture. One of the most critical factors that promote the organizational culture and develop the news agencies is " leadership style. " Accordingly, the present study aims to evaluate the impact of leadership style on organizational culture in news agencies under the Ministry of Culture and Islamic Guidance. Design/Methodology/Approach: The statistical population includes all employees of news agencies governed by the Ministry of Culture and Islamic Guidance, who were 500 people. Using Cochran's formula and a simple random sampling method, 217 people were selected as a statistical sample. A questionnaire was used to collect the data, and they were analyzed using SPSS software. Findings: The descriptive results of the research showed that the organizational culture average is 74.6%, leadership style average is 66.8%, organizational behavior average is 65.1%, individual behavior average is 52.9%, and internal intention average is 70.9%. Practical Implications: The inferential results of the study also showed that the relationship between leadership style and its dimensions (organizational behavior, individual behavior, and internal intention) with organizational culture is statistically significant. Also, the variables of organizational behavior, individual behavior, and internal intention (as dimensions of leadership style) were significantly effective in the regression model of organizational culture, which could explain 45% of the changes in organizational culture, from that the effect of organizational behavior was more than the other two variables. Originality/Value: This study confirms the positive effect of leadership style on organizational culture in news agencies under the Ministry of Culture and Islamic Guidance, which can improve the working situation.
Modelling Techniques to Improve the Quality of Food Using Artificial Intelligence

Artificial intelligence (AI), or AI/machine vision, is assuming an overwhelming part in the realm of food handling and quality affirmation. As indicated by Mordor Intelligence, AI in the food and refreshments market is required to enlist a CAGR of 28.64%, during the conjecture time frame 2018–2023. Artificial intelligence makes it workable for PCs to gain as a matter of fact, investigate information from the two data sources and yields, and perform most human assignments with an improved level of accuracy and proficiency. Here is a concise gander at how AI is expanding sanitation and quality activities. This exploration has along these lines tried to furnish policymakers with a way to assess new and existing strategies, while likewise offering a reasonable premise through which food chains orders can be made stronger through the thought of the executive’s practices and strategy choices. This survey centers on the AI applications according to four mainstays of food security that is food accessibility, food availability, food use, and strength.
Air Passengers’ Preferences for Aviation Voluntary Carbon Offsetting: A Co-benefits Perspective

Co-benefits are positive outcomes from voluntary carbon offsetting (VCO) programs beyond simple reduction in carbon emissions, which include biodiversity, air quality, economic, health, and educational benefits. Given the rates of aviation VCOs remain at less than 10%, this study investigated air passengers’ preferences for co-benefits as well as certification, location, and cost of VCO programs. Using discrete choice modeling, this study shows that aviation VCO programs with higher levels of co-benefits, particularly biodiversity and health benefits, are preferred by air passengers and confirms a preference for domestically based and certified VCO programs. The latent class choice model identified three classes with different preferences for VCO program attributes and demographic characteristics. The results of this study contribute to the knowledge of VCO co-benefits and imply that airlines should take note of this preference for biodiversity and health co-benefits when designing VCO programs and differentiate between market segments to increase the uptake of VCOs.
Mechanical characterisation of directionally frozen polycaprolactone scaffolds using 1,4-dioxane and glacial acetic acid for articular cartilage tissue engineering

Polymer scaffolds have shown promising results in bone and cartilage repair when the underlying property being designed for is morphological. Despite their ability to mimic the morphology of the native extracellular matrix, current studies have not managed to find a polymer-solvent-method combination that provides sufficient mechanical strength. This study performs a comparison of the strength, stiffness and structure of different biomedical scaffolds created using a thermally-induced phase separation (directional freezing) method with different solvents and polymer concentrations. 1,4-dioxane and glacial acetic acid are used with polycaprolactone, a combination which has not been studied before using the directional freezing method. Strength tests are performed with an Instron compression/tension tester and structural comparisons made using Scanning Electron Microscopy. It is found that higher polymer concentrations create stiffer and stronger scaffolds and that using 1,4-dioxane as a solvent creates substantially stiffer scaffolds than using glacial acetic acid. The 15 w/v% 1,4-dioxane scaffold had a maximum tensile strength of 840.7 ± 117.3 kPa compared to 93.5 ± 26.2 kPa for glacial acetic acid. The 1,4-dioxane scaffolds display significant cross-linking compared to glacial acetic acid scaffolds and also showed a porous structure similar to that of a cartilage extracellular matrix. This method produced scaffolds with a distinctive bi-phasic polymer structure, similar in morphology to cartilage which requires load bearing properties and lubricating properties. The study shows that thermally-induced phase separation can create porous scaffolds which mimic the physiological properties of the native extracellular matrix.
Comparative study of tension band wiring and malleolar screw fixation for the treatment of medial malleolus fracture

Background: Malleolar fractures are the most common type of ankle fractures. These intra-articula fractures need to be managed properly as they have high chance of non-union and are usually treated operatively. Open reduction and internal fixation with malleolar screw or tension band wiring (TBW) are mostly used treatment modalities for medial malleolus fracture. The objective of this study was to compare the functional and radiological outcome of patient who underwent TBW or malleolar screw fixation. Methods: It was a prospective comparative study conducted in 40 patients at Gandaki Medical College over the period of 24 months. Patients fulfilling the inclusion criteria were included in in the study. 20 patients were randomly selected in either group of malleolar screw and TBW which were followed for six months postoperatively. Functional outcome was measured using Olerud and Molander scoring system. Radiological outcome, adverse radiological outcome, range of motion and complications were studied and compared. Results: The mean age of TBW group was 41.3± 14.76 while in malleolar screw group it was 39.65±15.34. Male to female ratio in TBW group and malleolar screw group was 0.82 and 0.66 respectively which is not statistically significant. Mode of injury, fracture type pre and postoperative hospital stay and duration of surgery were statistically similar in both the groups. Most common mode of injury was RTA (50%) and twisting of ankle (35%). Higher rate of smoking was seen in malleolar screw group(40%) than in TBW group(20%) while alcohol consumption was seen in 40% TBW patients and 15% malleolar screw patients. Average duration of bony union was significantly higher in TBW group (8.32±1.61 weeks) compared to malleolar screw fixation group (10.69±3.35weeks) (P=0.008), however there is no significant difference in term of functional outcome score, radiological outcome and complication rate. Conclusions: There is no significant difference in term of functional outcome and complication rate between TBW or malleolar screw fixation for medial malleolar fracture however, patients treated with TBW fixation tend to show earlier radiological union.
The conflict market: Polarizing consumer culture(s) in counter-democracy

At the beginning of the millennium, consumer culture researchers predicted that people would increasingly demand that marketplace actors subscribe to contemporary ethics of liberal democracy. Although their prediction indeed came true, they did not foresee that an algorithm-powered media ecosystem in combination with growing authoritarian movements would soon come to fuel an increasingly polarized political landscape and challenge the very fundament of liberal democracy per se. In this macroscopic, conceptual article, I discuss three assumption-challenging logics—counter-democratic consumer culture, de-dialectical algorithmic manipulation, and growing illiberal consumer resistance—according to which the market increasingly monetizes the conflicts accompanying this polarization and, thereby, reinforces it. I call this new logic a conflict market and illustrate it through three, historically situated and currently conflicting, consumer ideoscapes—the neoblue, the neogreen, and the neobrown—between which consumers engage in marketized conflicts, not in a de-politicizing way, but in an increasingly un-politicizing, de-dialectical, and polarizing way. At the technologically manipulated conflict market, the role of marketers is to monetize politically sensitive topics by creating conflict, knowingly renouncing large groups of consumers, and giving fodder to the political extremes.

Computational modeling of biosludge drying

Considerable increases in industrial and urban wastewater sludge generation in recent years require proper treatment, such as thermal drying, and disposal. The sludge drying is a complex process involving simultaneous and coupled heat and mass transfer, which can be modeled by taking into account mass and heat balances, and assuming that water diffuses according to kinetic laws. This research implemented a simulation model for biosludge drying processes to predict the temperature and moisture distribution inside the biosludge, using the COMSOL Multiphysics® simulation program v5.2. A parametric analysis was carried out to determine the effect of initial moisture content on biosludge final temperature and moisture reduction. The simulated temperature and moisture content were experimentally validated and good agreement was observed between the simulation and experimental results. This model is a useful tool to optimize the drying process and develop better strategies for the control of the system.
Assessment of Serum Level of Interleukin-17 in Patients with Vitiligo

Vitiligo is a multifactorial disorder related to both genetic and non-genetic factors. The pathogenesis of vitiligo is associated with the melanocytes destruction that may result from immune and inflammatory mediators. The autoimmune theory is the most important theory about the pathogenesis of vitiligo. The aims of the study are the evaluation and assessment of serum levels of IL17 in vitiligo patients to reveal their possible role in pathogenesis of vitiligo and to correlate their levels with the severity of the disease. Patients and Methods: In this study, thirty patients (15 male and 15 females) were included in the present study and 30 apparently healthy, age and sex matched individuals were included as a control group. Patients were recruited from the outpatient clinic of Benha University Hospitals from Dermatology, Venereology and Andrology Department. All patients were subjected to full history, full dermatological and general examination. Measurement of serum levels of IL-17 using the commercially available ELISA kit. Results: The present study revealed significant increase in serum levels of IL-17 in patients than controls. Conclusion: Vitiligo is associated with increased serum level in IL-17 indicating that IL-17 may play a significant role in the pathogenesis of vitiligo.
Ecological Risk Assessment of Five Endocrine-Disrupting Compounds in Wastewater Treatment Plants from Monterrey, Mexico

The potential ecological risk of five residual endocrine-disrupting compounds (EDCs) in four wastewater treatment plants (WWTPs) was studied. The wastewater samples were collected in WWTPs of the Metropolitan Area of Monterrey, Mexico (designed as Monterrey City hereinafter) and 17β-estradiol (E2), 17α-ethinylestradiol (EE2), bisphenol A (BPA), 4-nonylphenol (4NP), and 4-tert-octylphenol (4TOP) were studied by SPE/GC-MS method. Results showed that all EDCs are widely distributed in WWTPs, finding high concentrations of BPA (450 ng/L) and EE2 (407.5 ng/L) in influents, while EE2 and 4TOP were the most abundant in effluents at levels from 1.6–26.8 ng/L (EE2) and < LOQ – 5.0 ng/L (4TOP), which corroborate that the wastewater discharges represent critical sources of EDCs to the aquatic environments. The potential ecological risk of residual EDCs was evaluated through risk quotients (RQs), and results indicated that the effluents of the WWTPs represent a high risk to exposed aquatic species, mainly due to the effect of residual estrogens E2 and EE2 which were considered as the most hazardous compounds among the studied EDCs, with RQ values up to 49.1 and 1165.2, respectively.
Risk Factors for Neonatal Sepsis in Secondary and Tertiary Care Hospitals of a District in Sri Lanka: A Case–Control Study

Abstract Objective The aim of this study was to determine the risk factors for neonatal sepsis. Methods A case–control study was performed in secondary and tertiary care hospitals of a district in Sri Lanka. Neonates who diagnosed with sepsis based on clinical criteria or culture positivity were taken as the case group (n = 240) and neonates born during the same period who had not been diagnosed with sepsis were taken as the control group (n = 240). The controls were recruited from the community. The study instruments were, pretested interviewer administered questionnaire, a check list and record sheets. Multiple logistic regression analysis was performed. The results were expressed as odds ratios (OR) with the 95% confidence intervals (CI). Results The independent risk factors for neonatal sepsis were history of abortions, still birth, and early neonatal deaths (OR: 6.78; 95% CI: 3.2–14.3), registration of pregnancy after 8 weeks of gestation (OR: 1.91; 95% CI: 1.07–3.4), total antenatal clinic visits ≤4 (OR: 7.18; 95% CI: 2.1–24.5), history of maternal fever prior to the week of delivery (OR: 2.74; 95% CI: 1.25–6.0) leaking amniotic fluid >18 hours (OR: 10.0; 95% CI: 2.1–47.4), performed >3 vaginal examinations before delivery (OR: 3.28; 95% CI: 2.1–24.5), meconium stained amniotic fluid (OR: 10.57; 95% CI: 3.7–29.7), mode of delivery by cesarean section, forceps or vacuum (OR: 2.33; 95% CI: 1.4–3.9), time of birth of the neonate being during on-call hours (OR: 2.12; 95% CI: 1.3–3.5), being a male baby (OR: 1.74; 95% CI: 1.1–2.8), and birth weight <2,500 g (OR: 5.17; 95% CI: 2.8–9.6) of neonates. Conclusion Most of the identified risk factors for neonatal sepsis were modifiable. Stringent implementation of guidelines and protocols would prevent neonatal sepsis.
Forecasting serve performance in professional tennis matches

Many research papers on tennis match prediction use a hierarchical Markov Model. To predict match outcomes, this model requires input parameters for each player’s serving ability. While these parameters are often computed directly from each player’s historical percentages of points won on serve and return, doing so fails to address bias due to limited sample size and differences in strength of schedule. In this paper, we explore a handful of novel approaches to forecasting serve performance that specifically address these limitations. By applying an Efron-Morris estimator, we provide a means to robustly forecast outcomes when players have limited match data over the past year. Next, through tracking expected serve and return performance in past matches, we account for strength of schedule across all points in a player’s match history. Finally, we demonstrate a new way to synthesize historical serve data with the predictive power of Elo ratings. When forecasting serve performance across 7,622 ATP tour-level matches from 2014-2016, all three of these proposed methods outperformed Barnett and Clarke’s standard approach.
Supervisory feedback to postgraduate research students: a literature review

Abstract Feedback is a complex socio-cultural construct, utilising various modalities over the lifespan of a research candidature. This study reports findings from a review of global literature on supervisory feedback to postgraduate research students. Three focus questions guided the review: students’ problems in receiving feedback, perceptions of positive feedback strategies, and potential improvements to the feedback process. The review method combined a systematic search process with explicit inclusion and exclusion criteria applied to literature published over the last decade. A detailed content analysis of 43 articles is reported in a thematically ordered narrative. Findings suggested that problems with feedback were found to be caused by the content, processes involved and the expectations of those involved. Second, feedback strategies that positively impacted learning and teaching capabilities of both students and supervisors were identified as most effective. Third, improvements to the feedback process were canvassed through the three key actors of institutions, supervisors and students, providing insights into the synergistic relationship among these actors. Further research is warranted as feedback processes and products are at the mercy of research supervision, which is increasingly operating in online environments spanning different time zones, with professional, cultural and linguistic diversities impacting feedback processes and products.
