An empirical analysis of construction organisations’ competitive strategies and performance

Purpose – The essence of strategy formulation is to assist an organisation obtain a strategic fit with its environment and help enhance organisational continuous improvement in achieving performance excellence. The purpose of this paper is to investigate the type of competitive strategies used by construction organisations in attaining their strategic goals in South Africa. Design/methodology/approach – The study employs an inductive research approach using a well-structured questionnaire to elicit information from large construction organisations based in South Africa. Findings – The research identifies five strategic attributes that could assist organisations to grow their businesses and enhance their returns. It reveals that all Porters’ generic competitive strategies are significantly related to organisational financial performance measures except focus strategy. The research found that three generic competitive strategies are positively related to non-financial performance and that differentiation and cost-leadership strategies are capable of assisting organisations’ achieve their financial performance goals. Practical implications – The study results will be of immense benefit to chief executive officers as well as managers of construction organisations in growing their businesses and enhancing their corporate performance. Originality/value – The paper contributes both theoretically and empirically to the current discussion and findings on competitive strategy and its relationship with organisational performance. The results presented in the paper have important implications for the implementation of competitive strategies in construction companies and future studies in the area of strategic management

Fungal enrichment of cassava peels proteins

About 60% of the cassava produced all over the world is used for human consumption. These peels waste were found to contain 42.6% carbohydrate, 1.6% protein, 12.1% ether extract, 5.0% total ash and 22.5% crude fibre. With the advent of biotechnology approaches, there are opportunities for economic utilization of agro industrial residues such as cassava peels waste. The Microorganisms isolated from the fermenting cassava waste were Aspergillus niger, A. flavus, and A. fumigatus. These and Trichoderma sp. from soil were studied for their ability to increase the protein content of cassava peels waste.Keywords: Cassava peels, Aspergillus flavus, Aspergillus niger, Aspergillus fumigatu

Impact of organisational structure and strategies on construction organisations' performance

There is an age long interest that the strategic management literature requires a better understanding of how the structure and strategy of an organisation influence its corporate performance. This standing interest increases the number of studies on structure-strategy-performance trilogy, but yet the outcomes are inconclusive. This paper examines how organisational structure and strategies influence organisation’s corporate performance, and investigate whether organisational structure has a moderating impact on the association between organisational performance and strategy. This is achieved by undertaking a Meta-analysis of literature on strategic management and explores the elements of organisational structure with respect to strategies and corporate performance. Based on the identified dimensions in literature, a questionnaire survey approach was adopted to obtain quantitative data from large construction organisations in South Africa. The data were analysed using correlation and regression analysis. The results revealed that organisational structure has an explanatory effect on the relationship between strategy and organisational corporate performance. The study provides a better understanding of the relationship between organisational structure, strategies and performance. It will also contribute to current discuss on the strategic planning practices in the global construction environment

Study on the short-term effects of increased alcohol and cigarette consumption in healthy young men's seminal quality

Many studies have reported a negative impact of lifestyle factors on testicular function, spermatozoa parameters and pituitary-gonadal axis. However, conclusions are difficult to draw, since studies in the general population are rare. In this study we intended to address the early and late short-term impact of acute lifestyle alterations on young men's reproductive function. Thirty-six healthy male students, who attended the Portuguese academic festivities, provided semen samples and answered questionnaires at three time-points. The consumption of alcohol and cigarette increased more than 8 and 2 times, respectively, during the academic festivities and resulted in deleterious effects on semen quality: one week after the festivities, a decrease on semen volume, spermatozoa motility and normal morphology was observed, in parallel with an increase on immotile spermatozoa, head and midpiece defects and spermatozoa oxidative stress. Additionally, three months after the academic festivities, besides the detrimental effect on volume, motility and morphology, a negative impact on spermatozoa concentration was observed, along with a decrease on epididymal, seminal vesicles and prostate function. This study contributed to understanding the pathophysiology underlying semen quality degradation induced by acute lifestyle alterations, suggesting that high alcohol and cigarette consumption are associated with decreased semen quality in healthy young men.publishe

The Complexity of Vascular and Non-Vascular Complications of Diabetes: The Hong Kong Diabetes Registry

Diabetes is a complex disease characterized by chronic hyperglycemia and multiple phenotypes. In 1995, we used a doctor-nurse-clerk team and structured protocol to establish the Hong Kong Diabetes Registry in a quality improvement program. By 2009, we had accrued 2616 clinical events in 9588 Chinese type 2 diabetic patients with a follow-up duration of 6 years. The detailed phenotypes at enrollment and follow-up medications have allowed us to develop a series of risk equations to predict multiple endpoints with high sensitivity and specificity. In this prospective database, we were able to validate findings from clinical trials in real practice, confirm close links between cardiovascular and renal disease, and demonstrate the emerging importance of cancer as a leading cause of death. In addition to serving as a tool for risk stratification and quality assurance, ongoing data analysis of the registry also reveals secular changes in disease patterns and identifies unmet needs

Mortality after infection with methicillin-resistant Staphylococcus aureus (MRSA) diagnosed in the community

<p>Abstract</p> <p>Background</p> <p>Outbreak reports suggest that community-acquired methicillin-resistant <it>Staphylococcus aureus </it>(MRSA) infections can be life-threatening. We conducted a population based cohort study to assess the magnitude of mortality associated with MRSA infections diagnosed in the community.</p> <p>Methods</p> <p>We used the United Kingdom's General Practice Research Database (GPRD) to form a cohort of all patients with MRSA diagnosed in the community from 2001 through 2004 and up to ten patients without an MRSA diagnosis. The latter were frequency-matched with the MRSA patients on age, GPRD practice and diagnosis date. All patients were older than 18 years, had no hospitalization in the 2 years prior to cohort entry and medical history information of at least 2 years prior to cohort entry. The cohort was followed up for 1 year and all deaths and hospitalizations were identified. Hazard ratios of all-cause mortality were estimated using the Cox proportional hazards model adjusted for patient characteristics.</p> <p>Results</p> <p>The cohort included 1439 patients diagnosed with MRSA and 14,090 patients with no MRSA diagnosis. Mean age at cohort entry was 70 years in both groups, while co-morbid conditions were more prevalent in the patients with MRSA. Within 1 year, 21.8% of MRSA patients died as compared with 5.0% of non-MRSA patients. The risk of death was increased in patients diagnosed with MRSA in the community (adjusted hazard ratio 4.1; 95% confidence interval: 3.5–4.7).</p> <p>Conclusion</p> <p>MRSA infections diagnosed in the community are associated with significant mortality in the year after diagnosis.</p

Star Formation and Dynamics in the Galactic Centre

The centre of our Galaxy is one of the most studied and yet enigmatic places in the Universe. At a distance of about 8 kpc from our Sun, the Galactic centre (GC) is the ideal environment to study the extreme processes that take place in the vicinity of a supermassive black hole (SMBH). Despite the hostile environment, several tens of early-type stars populate the central parsec of our Galaxy. A fraction of them lie in a thin ring with mild eccentricity and inner radius ~0.04 pc, while the S-stars, i.e. the ~30 stars closest to the SMBH (<0.04 pc), have randomly oriented and highly eccentric orbits. The formation of such early-type stars has been a puzzle for a long time: molecular clouds should be tidally disrupted by the SMBH before they can fragment into stars. We review the main scenarios proposed to explain the formation and the dynamical evolution of the early-type stars in the GC. In particular, we discuss the most popular in situ scenarios (accretion disc fragmentation and molecular cloud disruption) and migration scenarios (star cluster inspiral and Hills mechanism). We focus on the most pressing challenges that must be faced to shed light on the process of star formation in the vicinity of a SMBH.Comment: 68 pages, 35 figures; invited review chapter, to be published in expanded form in Haardt, F., Gorini, V., Moschella, U. and Treves, A., 'Astrophysical Black Holes'.
