Triggering the internationalization of Malaysian quantity surveying firms

Although there is an increasing trend of services being traded across borders, quantity surveying (QS) firms in the construction sector remain under-researched. The triggers for the increasing globalization of QS firms are not clear, nor how these triggers are perceived by managers at different levels. A questionnaire was administered in over 84 QS consultancy firms, and the results were analyzed using the repertory grid technique, allowing a comparison between the general respondents and a focus group of senior managers. The findings show that senior managers with significant experience realize the importance of a strong internal capability of the QS firm and the capability to develop innovative offerings, coupled with an awareness of the target market and the ability to secure revenue through key contracts. Firm- and location-specific factors were more important than other competitive advantages or foreign markets’ characteristics when deciding to globalize

RET Germline Mutations Identified by Exome Sequencing in a Chinese Multiple Endocrine Neoplasia Type 2A/Familial Medullary Thyroid Carcinoma Family

BACKGROUND: Whole exome sequencing provides a labor-saving and direct means of genetic diagnosis of hereditary disorders in which the pathogenic gene harbors a large cohort of exons. We set out to demonstrate a suitable example of genetic diagnosis of MEN 2A/FMTC (multiple endocrine neoplasia type 2/familial medullary thyroid carcinoma) using this approach. METHODOLOGY/PRINCIPAL FINDINGS: We sequenced the whole exome of six individuals from a large Chinese MEN2A/FMTC pedigree to identify the variants of the RET (REarranged during Transfection) protooncogene and followed this by validation. Then prophylactic or surgical thyroidectomy with modified or level VI lymph node dissection and adrenalectomy were performed for the carriers. The cases were closely followed up. Massively parallel sequencing revealed four missense mutations of RET. We unexpectedly discovered that the proband's daughter with MEN 2A-related MTC presented a novel p.C634Y/V292M/R67H/R982C compound mutation, due to the involvement of p.C634Y in the proband with MEN 2A and p.V292M/R67H/R982C in the proband's husband with FMTC. In the maternal origin, p.C634Y caused bilateral MTC in all 5 cases and bilateral pheochromocytoma in 2 of the 5; the earliest onset age was 28 years. In the paternal origin, one of the six p.V292M/R67H/R982C carriers presented bilateral MTC (70 years old), one only had bilateral C-cell hyperplasia (44 years), two had bilateral multi-nodules (46 and 48 years) and two showed no abnormality (22 and 19 years). CONCLUSIONS/SIGNIFICANCE: The results confirmed the successful clinical utility of whole exome sequencing, and our data suggested that the p.C634Y/V292M/R67H/R982C mutation of RET exhibited a more aggressive clinical phenotype than p.C634Y or p.V292M/R67H/R982C, while p.V292M/R67H/R982C presented a relatively milder pathogenicity of MTC and likely predisposed to FMTC

Functional high-k nanocomposite dielectrics for flexible transistors and inverters with excellent mechanical properties

The development of high performance flexible electronics requires dielectrics possessing a high dielectric constant and enhanced mechanical stability. In this study, we report on novel polymer nanocomposite dielectrics based on n-octadecylphosphonic acid (ODPA) functionalized aluminum titanate (AT) nanoparticles as dopants in poly(4-vinylphenol) (PVP). The robust surface layer covering the nanoparticles induces improved dielectric properties of the resulting composite films due to better interfacial adhesion. The nanocomposite layer with tunable dielectric permittivity and low leakage current is highly compatible on flexible substrates and has been deposited via a simple solution process. The air-stable p-type and n-type transistors fabricated on the composite dielectric layer exhibited superior electrical performance than those on the pristine polymer dielectric layer. The complementary inverters made from these transistors possessed a large signal gain and sharp switching. We systematically studied the electrical performance of the capacitors, transistors and inverters under different applied strains on flexible substrates. From the flexibility test, all these devices were found to be mechanically stable and environmentally robust, demonstrating that the composite dielectric layer is an excellent candidate for the future development of conformable sensors, portable displays and other flexible electronic applications
