    Description: Patient demand is often based on false perceptions about the safety of caesarean sections, which are not unambiguously supported by evidence.4 Patients leaving the hospital to find help in private clinics if public hospital providers do not agree to perform the requested caesarean section is no exception in Bangladesh.2 Additional beneficiaries of such practices are brokers, employed by private clinics who undermine efforts of public hospital providers and deviate patients to private clinics for a small reward.

    Description: This study sets out to examine the communication strategies (CSs) employed by non-native speaker novice science teachers (NNS-NvSTs) in teaching science in English. Twenty Secondary Four science lessons conducted by ten NNS-NvSTs were audio-recorded, transcribed and coded deductively as well as inductively. Perceptions on the meanings and uses of the CSs were also obtained from all ten NNS-NvSTs via stimulated recall and sixty-one Secondary Four students via group interview. The findings indicated that the NNS-NvSTs employed a variety of CSs for diverse intentions reflecting their multiple roles as teachers, novice teachers, and English language learners. In general, there is a high congruence between the NNS-NvSTs' and students' perception on the meanings and uses of CSs. The NNS-NvSTs were able to articulate the reasons for employing the specific CSs, allowing them to execute their roles as science teachers in the L2 science classroom. Nevertheless, there is still a need to address NNS-NvSTs strategic competence, particularly those CSs which require a greater production of the L2.

    Description: Ultraviolet irradiation (UV) is an important alternative to disinfection for production of potable water. Viable Escherichia coli is a widely used indicator for public health risk. However, UV efficacy is reduced by suspended solids that can act as both UV shielding and UV absorbing, agents. Failure of UV irradiation can lead to an enduring health legacy. Here the probabilistic Fr 13 methodology of Davey et al. (2015) is demonstrated for turbulent flow of feed water with suspended solids irradiated in an annular reactor and, a comparison made with the traditional deterministic method. The aim was to examine the impact of naturally occurring fluctuations in suspended solids concentration on failure to inactivate viable E. coli. A UV failure factor (p) is defined in terms of the design and actual log10 reduction in viable E. coli. UV irradiation is simulated using (Latin Hypercube) Monte Carlo sampling. Illustrative overall results show some 32.1% and 43.7% of apparent successful operations could unexpectedly fail over the long term due, respectively, to combined impact of random fluctuations in feed water flow (Q), lamp intensity (I0) and shielding and absorption of UV by suspended solids [conc]. This translates to four (4) failures each calendar month (the comparison rate without suspended solids is 16% or two (2) failures per month). An unexpected finding however is, although the initial presence of suspended solids as both UV shielding (median particle size 23μm) and absorbing agent has a highly significant impact on reducing UV efficacy, fluctuations in concentration of these in the feed water do not meaningfully impact overall vulnerability. UV failure is impacted highly significantly by fluctuation in feed water flow. It is concluded this is strong quantitative evidence to emphasize that solids should be removed prior to the UV reactor, and that an improved flow control be used to reduce variance on feed water flow, rather than increased UV dose. This work will be of benefit to operators of UV equipment and researchers in risk analyses. fx1 •UV efficacy for potable water significantly impacted by initial suspended solids.•However UV efficacy not vulnerable to fluctuations in suspended solids.•Overall UV efficacy is a mix of successful and unsuccessful inactivation of E. coli.•Results can be used to improve UV efficacy, reliability and safety.•Benefit to designers, operators and risk analysts of UV treatment for potable water.

    Description: The study investigated the effects of FIFA 11+ and HarmoKnee, both being popular warm-up programs, on proprioception, and on the static and dynamic balance of professional male soccer players. ; Under 21 year-old soccer players (n = 36) were divided randomly into 11+, HarmoKnee and control groups. The programs were performed for 2 months (24 sessions). Proprioception was measured bilaterally at 30°, 45° and 60° knee flexion using the Biodex Isokinetic Dynamometer. Static and dynamic balances were evaluated using the stork stand test and Star Excursion Balance Test (SEBT), respectively. ; The proprioception error of dominant leg significantly decreased from pre- to post-test by 2.8% and 1.7% in the 11+ group at 45° and 60° knee flexion, compared to 3% and 2.1% in the HarmoKnee group. The largest joint positioning error was in the non-dominant leg at 30° knee flexion (mean error value = 5.047), (p〈0.05). The static balance with the eyes opened increased in the 11+ by 10.9% and in the HarmoKnee by 6.1% (p〈0.05). The static balance with eyes closed significantly increased in the 11+ by 12.4% and in the HarmoKnee by 17.6%. The results indicated that static balance was significantly higher in eyes opened compared to eyes closed (p = 0.000). Significant improvements in SEBT in the 11+ (12.4%) and HarmoKnee (17.6%) groups were also found. ; Both the 11+ and HarmoKnee programs were proven to be useful warm-up protocols in improving proprioception at 45° and 60° knee flexion as well as static and dynamic balance in professional male soccer players. Data from this research may be helpful in encouraging coaches or trainers to implement the two warm-up programs in their soccer teams.

    Description: We aimed to investigate the effect of FIFA 11+ (11+) and HarmoKnee injury preventive warm-up programs on conventional strength ratio (CSR), dynamic control ratio (DCR) and fast/slow speed ratio (FSR) in young male professional soccer players. These ratios are related to the risk of injury to the knee in soccer players. ; Thirty-six players were divided into 3 groups; FIFA 11+, HarmoKnee and control (n = 12 per group). These exercises were performed 3 times per week for 2 months (24 sessions). The CSR, DCR and FSR were measured before and after the intervention. ; After training, the CSR and DCR of knee muscles in both groups were found to be lower than the published normal values (0.61, 0.72, and 0.78 during 60°.s, 180°.s and 300°.s, respectively). The CSR (60°.s) increased by 8% and FSR in the quadriceps of the non-dominant leg by 8% in the 11+. Meanwhile, the DCR in the dominant and non-dominant legs were reduced by 40% and 30% respectively in the 11+. The CSR (60°.s) in the non-dominant leg showed significant differences between the 11+, HarmoKnee and control groups (p = 0.02). As for the DCR analysis between groups, there were significant differences in the non-dominant leg between both programs with the control group (p = 0.04). For FSR no significant changes were found between groups. ; It can be concluded that the 11+ improved CSR and FSR, but the HarmoKnee program did not demonstrate improvement. We suggest adding more training elements to the HarmoKnee program that aimed to enhance hamstring strength (CSR, DCR and FSR). Professional soccer players have higher predisposition of getting knee injuries because hamstring to quadriceps ratio were found to be lower than the average values. It seems that the 11+ have potentials to improve CSR and FSR as well as prevent knee injuries in soccer players.

    Description: This study examines factors influencing and constraining the decision to recognize zero goodwill impairment in a sample of 52 Singaporean listed firms from 2010–2012. Using binary logistic regressions, the results reveal that firms that are approaching violation of their debt covenants have a higher likelihood of exercising the recognition choice, while a higher proportion of audit committee independence constrains this choice. The policy implication of this study is that to improve the quality of the financial statements, the relevant authorities need to monitor firms’ reporting incentives closely. This study contributes to the literature on IFRS by providing evidence that supports the applicability of the debt hypothesis in explaining the decision of Singaporean listed firms to recognize zero goodwill impairment.

    Description: Removal of low-concentration ammonia (1-10 ppm) from aquaculture wastewater was investigated via polysulfone (PSf)/zeolite mixed matrix membrane. PSf/zeolite mixed matrix membranes with different weight ratios (90/10, 80/20, 70/30 and 60/40 wt.%) were prepared and characterized. Results indicate that PSf/zeolite (80/20) was the most efficient membrane for removal of low-concentration ammonia. The ammonia elimination by PSf/zeolite (80/20) from aqueous solution for 10, 7, 5, 3 and 1 ppm of ammonia was 100%, 99%, 98.8%, 96% and 95% respectively. The recorded results revealed that pure water flux declined in higher loading of zeolite in the membrane matrix due to surface pore blockage caused by zeolite particles. On the other hand, ammonia elimination from water was decreased in higher contents of zeolite because of formation of cavities and macrovoids in the membrane substructure.

    Description: Neat cellulose acetate (CA) and CA/polysulfone (PSf) blend ultrafiltration membranes in the presence of polyvinylpyrrolidone as a pore former were prepared via a phase inversion technique. The prepared membranes were characterized by Fourier transform infrared, scanning electron microscopy, mechanical strength, water content, porosity, permeate flux and heavy metals (Pb, Cd, Zn and Ni) rejection to comprehend the impact of polymer blend composition and additive on the properties of the modified membranes. The water flux expanded by increasing of PSf content in the polymer composition. CA/PSf (60/40) had the highest flux among prepared membranes. Prepared blend membranes were able to remove heavy metals from water in the following order: Pb 〉 Cd 〉 Zn 〉 Ni. The CA/PSf (80/20) blend membrane had great performance among prepared membranes due to the high heavy metals removal and permeate flux.
