Development of a Web-Based Human Resource Sourcing System for Labour Only Contracts

Nowadays in some areas of Nigeria, it has been noticed that the search for a satisfactory team of labourers (skilled and unskilled) or even the right amount of people to undertake the job has become a laborious activity. Therefore, there is need to build a two-way partnership system linking construction firms with the required skilled labour and vice versa. The aim of this research is to develop a web-based human resource sourcing system for labour only contracts. The study made use of a questionnaire instrument and developed a web-based interface for skilled labour sourcing. The questionnaire was distributed to fifty (50) construction professionals who were selected through a convenience sampling technique. The data collected was analyzed using SPSS v.21. The design of the system was done using hypertext markup language (HTML) for authoring web pages. The study revealed that contractors’ sourcing techniques for skilled labour on construction projects were mostly by referral from colleagues and workers from past projects. The study identified the major barriers in sourcing for skilled labour on construction projects as the unavailability of trained skilled labour. The study revealed that years of experience, wages charged and behavior of the worker were major criteria considered while sourcing for skilled labour on construction projects. In conclusion, the study developed a web based human resource sourcing system for labour only contracts that incorporated the needs of the skilled labour and requirement of construction firms. It was recommended that construction professionals and contractors need to harness the benefits of web-based technologies. In addition, there is need to increase the information and communication technology (ICT) trainings of workers in the construction industry so has to have a successful integration of ICT and the construction industry

A systematic review of home-based dietary interventions during radiation therapy for cancer.

Purpose: Our objectives are to assess (1) the acceptability and feasibility of dietary interventions for patients undergoing radiation therapy (RT), and (2) the impact of dietary interventions on patient reported outcomes, toxicities, and survival. Methods: A PICOS/PRISMA/MOOSE selection protocol was used to include articles that evaluate adding dietary interventions to patients receiving RT. Acceptability was defined as (# accepting/# approached); feasibility was (# completing/# approached). Patient-reported outcomes were reported based on questionnaires used in each study and survival was measured from the date of diagnosis until death in each study. Level of evidence was assessed with Center for Evidence-Based Medicine (CEBM) criteria. Results: Sixteen articles were included; among these, 2027 patients were approached regarding the intervention, and 1661 accepted (81.9%); of these, 1543 (92.9%) completed the prescribed diet + RT course. The most common cancers included were gynecological, head and neck, and gastrointestinal. For patients with pelvic cancers, a high fiber diet may improve diarrhea (CEBM level 1b). Enteral nutrition formula, including formulas with proteins such as L-arginine, lipids such as eicosapentaenoic acids, glucids, and ribonucleotides, may help prevent of malnutrition in head and neck cancer patients undergoing RT (level 2b). Vitamin C and β-carotene may reduce of xerostomia in head and neck cancer patients; however, the studies evaluating these vitamins included vitamin E, which increases all-cause mortality (level 2b). No dietary intervention for cancer patients receiving RT has been shown to improve survival. Conclusion: There are limited data to support safe and efficacious use of dietary interventions during RT

Molecular Cloning and Sequence Analysis of a Novel P450 Gene Encoding CYP345D3 from the Red Flour Beetle, Tribolium castaneum

A novel cDNA clone encoding a cytochrome P450 gene has been isolated from the insecticide-susceptible strain of the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). The nucleotide sequence of the clone, designated CYP345D3, was determined. The cDNA is 1554 bp in length and contains an open reading frame from base pairs 32 to 1513, encoding a protein of 493 amino acid residues and a predicted molecular weight of 57466 Daltons. The putative protein contains the classic heme-binding sequence motif FxxGxxxCxG (residues 430–439) conserved among all P450 enzymes as well as other characteristic motifs of the cytochrome P450s. Comparison of the deduced amino acid sequence with other CYP members shows that CYP345D3 shares 91% identity with the previously published sequence of CYP345D1 from the T. castaneum genome project and the nucleotide sequence identity between them is less than 80%. Phylogenetic analysis of amino acid sequences from members of various P450 families indicated close phylogenetic relationship of CYP345D3 with CYP6 of other insects than those from mammals and amore distant relationship to P450 from other families. CYP345D3 was submitted to GenBank, accession number EU008544

Using Conducting Polymers as Active Agents for Marine Antifouling Paints

Antifouling coatings were prepared with paints containing polyaniline (PAni) and derivatives as active pigment, and evaluated by antifouling performance on metallic or polyvinyl chloride substrates. The paints, PAni and its derivatives were characterized by FT-IR spectrophotometry, thermogravimetric analysis, electrical conductivity and scanning electron microscopy. Coatings were also characterized by salt spray, leaching and erosion tests. Antifouling coatings’ performance was evaluated by immersion tests in a marine environment or in fresh water. Paints containing PAni-ES, PAni/DBSA and SPAN, and a co-biocide PyZn, showed antifouling performance similar to a commercial antifouling paint

On Combining Stated Preferences and Revealed Preferences Approaches to Evaluate Environmental Resources Having a Recreational Use

This work aims at analysing the value of recreational water uses for the Idro Lake (Lombardy, Northern Italy), which has been experiencing dramatic fluctuations in its levels in recent years, due to excessive productive withdrawal that affected recreational uses. It estimates the economic benefits deriving from recreational uses, by considering the current recreational demand and the hypothetical one obtained by considering an “improved quality” scenario. Through an on-site survey, we built a panel dataset. Following Whitehead et al. (2000) and Hanley et al. (2003) we get welfare estimates by combining SP and RP responses. The present CS is estimated in €134 per individual, whilst the increase in CS is estimated in €173 per individual. These figures can be confronted with the economic value of competitive uses and with the clean up costs, respectively, to infer some policy indications

An Exploration of the Experiences of Elite Youth Footballers: The Impact of Organisational Culture

The present study explored how the organisational cultural experiences of elite youth footballers shaped their identity development and behaviour. The first author occupied the position of sport psychology practitioner-researcher within one professional football club over a 3-year duration. Traditional ethnographic research methods were employed, including; observations, field notes, reflections, and informal interviews. A Cultural Sport Psychology (CSP) perspective on identity as a social construction, and research on the cultural characteristics of professional football were used as frameworks to make sense of the data. Despite the introduction of the Elite Player Performance Plan (EPPP) in 2012, the traditional masculine culture of professional football dominated the studied club. Creative non-fiction vignettes revealed that youth players were encouraged to develop their self-stories focused on a single-minded dedication to professional football. The limited identity-related resources offered at both club, and cultural level is detrimental for players in terms of their well-being, and long term psychological development. From the results of this study, we suggest that future sports psychology practice within professional football may best be delivered at an organisational level. However, in order for a sport psychologist to be effective in this role they must develop an understanding of the sub-cultural features and characteristics of the organisation. In line with this, there would be great value in introducing a focus on organisational culture within sport psychology professional training and education routes

Validity of willingness to pay measures under preference uncertainty

This paper is part of the project ACCEPT, which is funded by the German Federal Ministry for Education and Research (grant number 01LA1112A). The publication of this article was funded by the Open Access fund of the Leibniz Association. All data is available on the project homepage (https://www.ifw-kiel.de/forschung/umwelt/projekte/accept) and from Figshare (https://dx.doi.org/10.6084/m9.figshare.3113050.v1).Recent studies in the marketing literature developed a new method for eliciting willingness to pay (WTP) with an open-ended elicitation format: the Range-WTP method. In contrast to the traditional approach of eliciting WTP as a single value (Point-WTP), Range-WTP explicitly allows for preference uncertainty in responses. The aim of this paper is to apply Range-WTP to the domain of contingent valuation and to test for its theoretical validity and robustness in comparison to the Point-WTP. Using data from two novel large-scale surveys on the perception of solar radiation management (SRM), a little-known technique for counteracting climate change, we compare the performance of both methods in the field. In addition to the theoretical validity (i.e. the degree to which WTP values are consistent with theoretical expectations), we analyse the test-retest reliability and stability of our results over time. Our evidence suggests that the Range-WTP method clearly outperforms the Point-WTP method.Publisher PDFPeer reviewe
