FACTORS INFLUENCING TEACHER JOB SATISFACTION AND COMMITMENT AT SENIOR HIGH SCHOOLS IN THE GREATER ACCRA REGION, GHANA

This paper examines the determinants of teacher’s job satisfaction and the implications on their job commitment. The study concentrated on pre-tertiary school teachers in the Greater Accra region, Ghana. Quantitative survey approach based on positivist philosophies research design was adopted in gathering data. Over 96% (676) participated fully in answering questionnaire from a sampling frame of 700. For the analysis of data, a number of descriptive statistical tests and in combination of Exploratory Factor Analysis (EFA) and Confirmation Factor Analysis (CFA) was used. The main tools used were mean, standard deviation, frequency and Ordinary Least Squares (OLS) regression. The findings generally shows teachers are satisfied with their job profession intrinsically and this had impacted on their commitment level. However, extrinsically, results indicates teachers are not satisfied especially in the area of salary and other rewards and better conditions of service; career advancement; recognition and promotion policy; among others. Notwithstanding, the results have shown that teachers were committed to their professional job basically due to the love of the job and the students they teach. Article visualizations:
Physical education professional in basic health attention: the recognition from the family health team

This study aims to analyze the importance of PEF in SUS, through the knowledge of professionals of Family Health Teams in 19 Basic Health Units (BHU) in the city of Apucarana, state of Parana. This is a cross-sectional quantitative study portrait of reality done using a self-answered questionnaire. A total of 68 professionals participated in the research: 13 community health workers (19%), 15 nursing technicians (22%), 13 dentists (19%), 14 nurses (20%), and 13 doctors (19%). Of the professionals, 32 of them (47%) have worked for over 10 years in the FHS, 19 (27%) from 6 to 10 years, 11 (16%) from 1 to 5 years, and 6 (9%) for less than 1 year. About 66 professionals have knowledge about NASF and 62 professionals know that the Physical Education Professional is part of the NASF team. Finally, 86% of professionals advise users to look for the Physical Education Professional and 100% believe that the practice of physical activity reduces the use of pharmacological intervention and avoids non-communicable chronic diseases. We can conclude that the professionals who make up the Family Health Strategy Teams in the city of Apucarana, state of Parana, are aware that the Physical Education Professional is part of NASF and know the benefits it provides to the system and its users.
Backcasting, Nowcasting, and Forecasting Residential Repeat-Sales Returns: Big Data meets Mixed Frequency

The Case-Shiller is the reference repeat-sales index for the U.S. residential real estate market, yet it is released with a two-month delay. We find that incorporating recent information from 71 financial and macro predictors improves backcasts, now-casts, and short-term forecasts of the index returns. Combining individual forecasts with recently-proposed weighting schemes delivers large improvements in forecast accuracy at all horizons. Additional gains obtain with mixed-data sampling methods that exploit the daily frequency of financial variables, reducing the mean square forecast error by as much as 13% compared to a simple autoregressive benchmark. The forecast improvements are largest during economic turmoils, throughout the 2020 COVID-19 pandemic period, and in more populous metropolitan areas.
Effects of L1 morphological type on L2 morphological awareness

Previous studies on bilingual children have shown a significant correlation between first language (L1) and second language (L2) morphological awareness and a unique contribution of morphological awareness in one language to reading performance in the other language, suggesting cross-linguistic influence. However, few studies have compared advanced adult L2 learners from L1s of different morphological types or compared native speakers with advanced learners from a morphologically more complex L1 in their target-language morphological awareness. The current study filled this gap by comparing native English speakers (analytic) and two L2 groups from typologically different L1s: Turkish (agglutinative) and Chinese (isolating). Participants’ morphological awareness was evaluated via a series of tasks, including derivation, affix-choice word and nonword tasks, morphological relatedness, and a suffix-ordering task. Results showed a significant effect of L1 morphological type on L2 morphological awareness. After accounting for L2 proficiency, the Turkish group significantly outperformed the Chinese group in the derivation, morphological relatedness, and suffix-ordering tasks. More importantly, the Turkish group significantly outperformed the native English group in the morphological relatedness task even without accounting for English proficiency. Such results have implications for theories in second language acquisition regarding representation of the bilingual lexicon. In addition, results of the current study underscored the need to guard against the comparative fallacy and highlighted the influential effect of L1 experience on the acquisition of L2 morphological knowledge.
AMOC and Climate Responses to Dust Reduction and Greening of Sahara during the Mid-Holocene

The North Africa was green during the mid-Holocene (6 ka) and emitting much less dust to the atmosphere than in present day. Here we use a fully coupled atmosphere-ocean general circulation model, CESM1.2. 2, to test the impact of dust reduction and greening of Sahara on the Atlantic Meridional Overturning Circulation (AMOC) during this period. Results show that dust removal leads to a decrease of AMOC by 6.2 % while greening of Sahara with 100 % shrub (100 % grass) causes an enhancement of the AMOC by 6.1 % (4.8 %). The AMOC is increased by 5.3 % (2.3 %) when both the dust reduction and green Sahara with 100 % shrub (100 % grass) are considered. The AMOC changes are primarily due to the precipitation change over the west subtropical North Atlantic, from where the salinity anomaly is advected to the deepwater formation region. Global mean surface temperature increases by 0.09 °C and 0.40 °C (0.25 °C) when global dust is removed and when North Africa and Arabian region are covered by shrub (grass), respectively, showing a dominating effect of vegetation over dust. The comparison between modeled and reconstructed sea-surface temperature is improved when the effect of vegetation is considered. The results may have implication for climate impact of future wetting over North Africa, either through global warming or through building of solar farms and wind farms.
Factors Affecting Quality of Life in Liver Transplant Candidates: An Observational Study

Health-related quality of life (HRQOL) before and after liver transplant (LT) is an important outcome in LT candidates as, in these patients, HRQOL is commonly impaired. However, evidence regarding factors that influence HRQOL in patients with end-stage liver disease is inconclusive. The aim of the present study was to identify factors associated with poor HRQOL. An observational study was conducted over LT candidates. The 36-item Short Form Health Survey (widely used to assess HRQOL) and the Hospital Anxiety and Depression Scale were administered to 211 patients during the pre-transplant assessment. Baseline demographic and clinical data were also collected. Multiple regression analysis was performed to investigate risk factors for poor HRQOL. Female sex (lower B = 7.99 95%C = 0.07–15.92, higher B = 18.09 95%CI = 7.56–28.62), encephalopathy (lower B = −9.45, 95%CI = −14.59–−4.31, higher B = −6.69, 95%CI = −13.13 to −0.25), higher MELD scores (lower B = −1.14, 95%CI = −1.67 to −0.61, higher B = −0.33, 95%CI = −0.65 to −0.12), anxiety (lower B = −3.04 95%C = −4.71 to −1.36, higher B = −1.93 95%CI = −3.39 to −0.47)and depression (lower B = −3.27 95%C = −4.46 to −2.08, higher B = −1.02 95%CI = −1.90 to −0.13) symptoms were associated to poorer HRQOL. Psychosocial interventions should be addressed to liver transplant candidates, especially to women, patients with anxiety, depression or episodes of encephalopathy, in order to prevent the impact that these conditions can have on HRQOL.
Luminescent Zinc Phosphonates for Ratiometric Sensing of 2,4,6-Trinitrophenol and Temperature

Three new luminescent zinc phosphonates, [Zn(H2L)(H2O)2]·H2O (1), [Zn(H2L)] (2), and [Zn(H3L)2(H2O)2]·3H2O (3), have been hydrothermally synthesized based on 1-hydroxy-2-(imidazo(1,2-a)pyridin-3-yl)ethylidene-1,1-diphosphonic acid (H4L). Single-crystal X-ray diffraction reveals that compounds 1–3 are a binuclear cluster, two-dimensional polar sandwich-like framework, and mononuclear unit, respectively. Compounds 1–2 exhibit remarkable capabilities to detect the trace of 2,4,6-trinitrophenol rapidly and quantitatively through luminescent quenching. It is worth to note that compounds 1–2 can be readily recovered and reused. On the other hand, compound 1 features dual emissions which facilitates it to serve as a useful self-calibrated ratiometric luminescent thermometer in the temperature range of 77–243 K, as well as a more reliable and sensitive intensity-based luminescent thermometer in the temperature range of 10–60 °C. Furthermore, compound 1 has good stability under simulated physiological conditions, .
Pyrolysis of Municipal Sewage Sludge to Investigate Char and Phosphorous Yield together with Heavy-Metal Removal—Experimental and by Thermodynamic Calculations

Sewage sludge is regarded as a potential source for soil fertilizer However, the direct utilization of sewage sludge in agricultural land is restricted since it also contains heavy metals, pathogens, and toxic compounds. Pyrolysis of the sewage sludge destroys the organic pollutants and partly volatilizes the heavy metals. In this study, pyrolysis of sewage sludge was carried out in order to determine the optimum residence time and temperature to recover the phosphorous and remove heavy metals from the resultant sewage sludge char (SSC). Pyrolysis was conducted on dried sewage sludge (DSS) by means of thermogravimetric analysis (TGA) and high-temperature oven with an N2-atmosphere. Microwave Plasma-Atomic Emission Spectroscopy (MP-AES) was used to determine the concentration of P and trace elements in the resulting solid char fraction. A combination of chemical fractionation (step-by-step leaching) of the DSS and thermodynamic equilibrium calculations were utilized to estimate the availability of phosphorous and removal of heavy metals in the SSC fraction at different temperatures. The results from the thermodynamics calculation were in line with the measured chemical composition of the SSC. Furthermore, the energy contents of the SSC obtained at different temperatures were measured. The pyrolysis evaluation results indicate that phosphorous was enriched in the char, while lead, zinc, and cadmium were significantly removed.
Spontaneous Mammary Tumor with Concurrent Cavernous Hemangioma in Albino Mice- A Rare Case Report from Mizoram, India

Background: Mouse mammary tumor is a common neoplasm of the species. Mice is an established model for human breast cancer studies and in recent times for transgenic studies. Hemangiomas are tumors of blood vascular system. Hemangioma with breast cancer is reported in human beings. Presented study describes an unusual case of concurrent mouse mammary tumor and cavernous hemangioma from Mizoram, India.Methods: A mortality of 8 out of a colony of 25 female albino mice was observed due to mammary tumors. Dead mice were thoroughly necropsied and tissue samples were collected from different parts of each tumor mass and fixed in neutral buffered formalin. The fixed tissues were processed for hematoxylin and eosin staining by routine paraffin embedding, microtomy and staining protocol. Result: Gross examination revealed variable sized tumors on abdomen of affected mice. Histopathology revealed two different forms of mammary tumor viz, acinar and solid mammary carcinoma. Most peculiar finding was remarkable presence of large, endothelial lined cavernous spaces with presence of stagnant blood. These were diagnosed as cavernous hemangioma. Perusal of available literature did not reveal any report of cavernous hemangioma occurring with mouse mammary tumor, while it is found in other species including human beings.
Polarimetric Properties of Event Horizon Telescope Targets from ALMA

We present the results from a full polarization study carried out with ALMA during the first VLBI campaign, which was conducted in Apr 2017 in the $\lambda$3mm and $\lambda$1.3mm bands, in concert with the Global mm-VLBI Array (GMVA) and the Event Horizon Telescope (EHT), respectively. We determine the polarization and Faraday properties of all VLBI targets, including Sgr A*, M87, and a dozen radio-loud AGN. We detect high linear polarization fractions (2-15%) and large rotation measures (RM $>10^{3.3}-10^{5.5}$ rad m$^{-2}$). For Sgr A* we report a mean RM of $(-4.2\pm0.3) \times10^5$ rad m$^{-2}$ at 1.3 mm, consistent with measurements over the past decade, and, for the first time, an RM of $(-2.1\pm0.1) \times10^5$ rad m$^{-2}$ at 3 mm, suggesting that about half of the Faraday rotation at 1.3 mm may occur between the 3 mm photosphere and the 1.3 mm source. We also report the first unambiguous measurement of RM toward the M87 nucleus at mm wavelengths, which undergoes significant changes in magnitude and sign reversals on a one year time-scale, spanning the range from -1.2 to 0.3 $\times\,10^5$ rad m$^{-2}$ at 3 mm and -4.1 to 1.5 $\times\,10^5$ rad m$^{-2}$ at 1.3 mm. Given this time variability, we argue that, unlike the case of Sgr A*, the RM in M87 does not provide an accurate estimate of the mass accretion rate onto the black hole. We put forward a two-component model, comprised of a variable compact region and a static extended region, that can simultaneously explain the polarimetric properties observed by both the EHT and ALMA. These measurements provide critical constraints for the calibration, analysis, and interpretation of simultaneously obtained VLBI data with the EHT and GMVA.
Mechanical Stirring Induces Heteroaggregate Formation and Self‐assembly of Pseudoenantiomeric Oxymethylene Helicene Oligomers in Solution

A 1:1 mixture of pseudoenantiomeric oxymethylene helicene (P)-pentamers and (M)-hexamers formed hetero-double-helix and self-assembled as a result of mechanical stirring in solution at 25 °C. No aggregation occurred without stirring, and heteroaggregation was accelerated at high stirring rates. Repeatedly alternating between mechanical stirring and stopping respectively induced and then ceased the heteroaggregation. Sonication also promoted the heteroaggregation, which did not occur at high pressures or during centrifugation. Mechanisms based on friction due to mechanical stirring, which generated local and temporal high-temperature domains, are considered. It is shown that different methods of mechanical stimulation, namely, stirring and surface contact, induce enantiomeric heteroaggregate formation.
Utilization of prilled fat on milk production and milk quality fed to lactating dairy cows

The objective was to determine the effects of supplemental prilled fat in lactating dairy cows’ diet on milk production and milk quality. There hasn’t been any novel information about the effect of different content of palmitic acid in the prilled fat. The study conducted for 49 days, consisted of 42 days of adaptation and 7 days of data collection. Sixteen mid-lactation multiparous Friesian Holstein cows were assigned in a completely randomized block design experiment of four dietary treatments and four groups. The treatments were: basal diet (T1), basal diet + 2% of prilled fat with 75% of palmitic acid (T2), basal diet + 2% of prilled fat with 85% of palmitic acid (T3), and basal diet + 2% of prilled fat with 95% of palmitic acid (T4). The basal diet that used containing approximately 60% forages and 40% grains. The total dry matter intake resulted highest in T2 (P<0.05) with an average 17.42 kg/head/day, whereas, the milk production was not affected. The milk quality-analysed were total solid (TS), %fat, %protein, %lactose and solid non-fat (SNF). The %fat resulted the best in T2 with average 4.22% (P<0.05), while there were not any significant differences in TS, %protein, %lactose and SNF.
Higher Total White Blood Cell and Neutrophil Counts Are Associated With Increased Stroke Mortality Risk: The Guangzhou Biobank Cohort Study

Background: To investigate the relations of white blood cell (WBC) count and its dynamic change with future stroke mortality risk in a relatively healthy elderly population.Methods: A total of 27811 participants without stroke history at baseline were included and followed up for an average of 11.5 (SD=2.3) years. After review of available records, 399 stroke (277 ischaemic and 172 haemorrhagic) deaths were recorded among all-cause mortality. Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Results: Compared with the lowest quartile, the highest quartile of WBC count showed 53% and 67% increased mortality risk for total (adjusted HR [aHR]=1.53, 95% CI 1.16-2.02, P=0.003) and haemorrhagic (aHR=1.67, 95% CI 1.10-2.67, P=0.03) stroke, respectively; the highest neutrophil count showed 45% and 65% increased mortality risk for total (aHR=1.45, 95% CI 1.10-1.89, P=0.008) and ischaemic (aHR=1.65, 95% CI 1.10-2.47 P=0.02) stroke. The same results found for total and ischaemic stroke but not for haemorrhagic stroke were observed for both WBCs and neutrophils within the normal range level after further C-reactive protein (CRP) adjustment. Compared with the stable group, the 25% increased groups of both WBCs (aHR=1.60, 95% CI 1.07-2.40, P=0.02) and neutrophils (aHR=1.45, 95% CI 1.02-2.05, P =0.04) showed 60% and 45% increased stroke mortality risk, respectively.Conclusions: These findings support the role of WBCs, especially neutrophils, as simple, inexpensive and readily available predictors of future stroke mortality in an elderly population. Trial registration: The Guangzhou Medical Ethics Committee of the Chinese Medical Association approved the study.
Factors Influencing Arable Crop Farmers’ Willingness to Adopt Bio-Organic Technology in Ondo State, Nigeria

The study analysed factors influencing arable crop farmers’ willingness to adopt bio-organic technology in Ondo State. Multi-stage sampling procedure was used to select 180 respondents for the study. Questionnaire was used to collect data which were analysed with percentages, 4-point likert-type scale and logit regression model. The findings revealed that the females (67.0%) dominated arable crop farming, the mean age was 41 years and 55.6% had formal education. All the respondents are aware of mixed cropping and crop rotation and less than 50% were aware of alley cropping (43.2) and biological pest control (26.6). The majority (67.6%) of the arable crop farmers had unfavourable perception of bio-organic technology. The study showed that increase in extension visit, membership of farmers’ group, access to information and education positively increase the likelihood of farmers to adopt bio-organic technology. Enhanced extension services that would adequately support farmer and extended education programs geared towards broadening farmers’ knowledge on bio-organic technology should be promoted.
What is the effect of smoking on postoperative outcomes after ankle-fracture surgery? A retrospective cohort study

Background: Smoking is a primary modifiable factor associated with postoperative complications after ankle-fracture fixation. Although most literature concludes that smoking is detrimental to wound healing and tissue oxygenation, there remains disparity in studies reporting on outcomes after ankle-fracture surgery. Therefore, our purpose was to evaluate the differences in (1) infection; (2) malunion and nonunion rates; (3) return to the operating room; and (4) overall complication rates between smokers and nonsmokers who underwent ankle-fracture fixation. Methods: Patients who had ankle-fracture surgery at our institution between July 2012 and April 2014 were retrospectively identified. Information was collected on demographics, injury data, and smoking status. The incidences of infection, malunion or nonunion, and postoperative complications and revision surgery were determined. A P value of 0.05 was used to determine statistical significance. There were 263 patients included in this study, 112 smokers and 151 nonsmokers. Results: The overall infection rate in the smoker cohort was 29.4% compared with 9.9% in the nonsmoker cohort, and there was a four-fold higher rate of malunions and nonunions in the smoker compared with the nonsmoker cohort (8.7% vs. 2%). The overall rate of return to the operating room was higher in the smoker compared to nonsmoker group (67.8 vs. 43.7%), as well as complication rates (8.9% vs. 2.6%; odds ratio [OR] 3.6, 95% confidence interval [CI] 1.1 to 11.8). Conclusions: This study showed that tobacco smoking had a direct adverse effect on infection rates, union, and return to the operating room in patients who underwent ankle-fracture fixation. These findings reiterated the importance of advocating for smoking cessation to improve postoperative clinical outcomes. Level of Evidence: Level III.
In Vitro PAH-Binding Ability of Lactobacillus brevis TD4

Abstract Recently, there has been a growing attention in utilizing microorganisms, particularly, lactic acid bacteria and probiotics in reduction of various toxic compounds such as heterocyclic amines, polycyclic aromatic hydrocarbons, acrylamide, heavy metals and mycotoxins. Therefore, this study was aimed to evaluate detoxification ability of Lactobacillus brevis TD4 in removal of four PAHs (PAH4), namely, Benzo(a)anthracene (BaA), Benzo(a)pyrene (BaP), Benzo(b)fluoranthene (BbF) and Chrysene (Chr) from artificially contaminated phosphate buffer saline (PBS). In this regard, response surface methodology (RSM) in combination with Box-Behnken design was applied to investigate the effect of incubation time (1-24 h), PAH concentration (5-15 ppm), pH (3-7) and bacterial population (7-9 log CFU/mL) at three levels on binding rate of BaA, BaP, BbF and Chr as a response. The results showed that L. brevis TD4 was able to remove PAH4 from PBS and this removal was entirely toxin-specific. The results also showed that pH, bacterial population, initial concentration of each PAH and time were the variables that significantly affected BaA, BbF, BaP and Chr binding rate by L. brevis TD4 in linear and quadratic manners. Furthermore, there was an interaction between initial concentration of each PAH and time in removal of BaA, BbF, BaP and Chr. In this respect, the highest binding rate of each PAH occurred at pH near 5, initial concentration of 10 ppm, bacterial population of 109 CFU/mL and after 24 h incubation. It can be generally concluded that according to the PAH type and concentration, there is a definite incubation time, pH and bacterial population to obtain maximum binding rate of BaA, BaP, BbF and Chr.
