Assessment of Health Care Workers’ Knowledge and Practice Toward Infection Standard Precautions in Primary Health Care setting, Buraidah, Saudi Arabia

Background: This study aimed to assess knowledge of standard precautions (SPs) and infection control by healthcare workers (HCWs) at the primary healthcare level in Buraidah City, Qassim Region, Saudi Arabia. Methods: A cross sectional study enrolled HCWs (doctors, nurses, lab workers) from 20 primary healthcare (PHC) centers in Buraidah. Two-hundred participants were selected randomly to participate in this study. Data was collected by a pretested, self-administered questionnaire, containing 29 items about basic knowledge of components of SPs and infection control including hand hygiene, personal protective equipment, sharps disposal, environmental sanitation and care of healthcare providers. Data was entered and analyzed using SPSS. Results: The mean age of HCWs was 35.7 (SD±6.6) years. Females represented (51.5%) of the study participants. History of receiving formal training in standard infection control precaution in the last three years was mentioned by almost two-thirds (68.5%) of them. About 102 (51.0%) of the HCWs had adequate level of knowledge (>5 correct answers) regarding standard precautions(SPs) of infection control. The younger (p=0.020), non-Saudi healthcare workers (p<0.001), physicians (p<0.001); particularly consultants (p=0.018), were more knowledgeable than their counterparts. The barriers of improper use of PPEs reported by HCWs were uncomfortable (61.5%), some patients feel stigmatized when PPEs are used (60.5%), shortage in items at PHCC (54%) and workload due to patients’ over-crowding (49%). Conclusion: Generally the study finding revealed adequate knowledge of SPs among the study participants. However, inadequate knowledge particularly concerning the disposal of sharp instruments and hand hygiene were also detected. These findings highlighted the necessity of the provision of a comprehensive training program to ensure compliance with infection control measures by HCWs. Key words: knowledge, practice, infection standard precautions, primary health care
A qualitative exploration of post-migration stressors and psychosocial well-being in two asylum reception centres in Belgium

Purpose Prolonged exposure to daily stressors can have long-term detrimental implications for overall mental health. For asylum seekers in European Union transit or destination countries, navigating life in reception centres can represent a significant burden. The purpose of this study was to explore post-migration stressors during residency in reception centres, and to formulate recommendations for adequate service provision in Belgium. Design/methodology/approach Research was conducted in two reception centres in Belgium. A total of 41 in-depth interviews were carried out with asylum seeker residents (n = 29) and staff (n = 12). Purposive recruitment was used for asylum seekers (for variation in length of centre residency and family status) and staff (variation in job profiles). Interviews were conducted in English, French or with a translator in Arabic or Dari. Interviews were audio-recorded, transcribed verbatim and manually coded using thematic analysis. Findings Asylum seekers face significant constraints with regard to their living conditions, including total absence of privacy, overcrowding and unhygienic conditions. These act as continuous and prolonged exposure to daily stressors. Several barriers to accessing activities or integration opportunities prevent meaningful occupation, contribute towards eroded autonomy and isolation of asylum seeker residents. Inadequate capacity and resources for the provision of psychosocial support in reception centres leads to a sense of abandonment and worthlessness. Originality/value Analysis indicates that structural and practical challenges to adequately support asylum seekers are rooted in policy failures necessary for appropriate resourcing and prioritization of preventative measures. Such deliberate decisions contribute towards state deterrence strategies, eroding both individual well-being and manufacturing a crisis in the systems of support for asylum seekers.
Auditor career concerns, audit fees and audit quality

ABSTRACT This study examines how engagement signing auditors’ career concerns affect audit fees and audit quality. Based on a sample of listed companies in China, we find that audit fees and audit quality are lower for firms audited by auditors in their early years of being signing auditors. Moreover, we find that the results are more pronounced for signing auditors in local Chinese audit firms than those in Big 4. These results may be attributed to differential quality control mechanism and incentive systems. Our results have implications for regulators and audit firms in formulating standards and guidelines on monitoring newly promoted signing auditors.
Multimodel Ensemble Projections of Wave Climate in the Western North Pacific Using CMIP6 Marine Surface Winds

For decades, the western North Pacific (WNP) has been commonly indicated as a region with high vulnerability to oceanic and atmospheric hazards. This phenomenon can be observed through general circulation model (GCM) output from the Coupled Model Intercomparison Project (CMIP). The CMIP consists of a collection of ensemble data as well as marine surface winds for the projection of the wave climate. Wave climate projections based on the CMIP dataset are necessary for ocean studies, marine forecasts, and coastal development over the WNP region. Numerous studies with earlier phases of CMIP are abundant, but studies using CMIP6 as the recent dataset for wave projection is still limited. Thus, in this study, wave climate projections with WAVEWATCH III are conducted to investigate how wave characteristics in the WNP will have changed in 2050 and 2100 compared to those in 2000 with atmospheric forcings from CMIP6 marine surface winds. The wave model runs with a 0.5° × 0.5° spatial resolution in spherical coordinates and a 10-min time step. A total of eight GCMs from the CMIP6 dataset are used for the marine surface winds modelled over 3 h for 2050 and 2100. The simulated average wave characteristics for 2000 are validated with the ERA5 Reanalysis wave data showing good consistency. The wave characteristics in 2050 and 2100 show that significant decreases in wave height, a clockwise shift in wave direction, and the mean wave period becomes shorter relative to those in 2000.
Photoalignmentability of silsesquioxane-containing citraconimide and its solvent-induced surface enrichment in PMMA matrix

ABSTRACT Photo-reactive polymer of silsesquioxane-containing citraconimide (SQ-CI) was synthesised and evaluated as a photoalignment layer for polymerisable liquid crystals (PLC). A generation mechanism of the anisotropy by the linearly polarised ultraviolet light was discussed by comparing optical retardation of SQ-CI with theoretical calculations using density functional theory. In addition, the SQ-CI and poly(methyl methacrylate) were blended for a model of unification of photoalignment layer and protection layer in liquid crystal display. The orientation of PLC on the blend film was dominated by the solvent used for the sample preparation of PMMA/SQ-CI blend. We found that the SQ-CI was enriched at surface of the blend film prepared from the ? -butyrolactone solution, while not in the case of the film prepared from cyclopentanone solution. The surface enrichment in the film prepared from ? -butyrolactone solution does not follow the conventional mechanism which is that the lower surface free energy component segregates to the blend surface, because the surface free energy of SQ-CI is higher than that of PMMA. Based on the result of solvent-annealing effect and photoalignmentability, we concluded that the mechanism of surface enrichment was explained due to the difference of affinity between the polymer and the solvent.

Investigation of Ni­Al hydroxide with silver addition as an active substance of alkaline batteries

Layered double hydroxides with different ratios of nickel and aluminum in the presence of Ag + ions and without silver have been synthesized: Ni: Al – 80 %: 20 %, Ni: Al: Ag – 80 %: 15 %: 5 % and 75 %: 15 %: 5 %. The obtained nickel hydroxide powders have a structure similar to α-Ni(OH) 2 with a large number of crystal lattice defects. As a result of galvanostatic charge-discharge cycling, it was revealed that the addition of silver in the chemical synthesis stage increases the hydroxide utilization coefficient at fast discharges but decrease it at slow discharges. A possible mechanism that explains the influence of added silver during synthesis on discharge characteristics of hydroxide powders was proposed. The mechanism is that silver oxide, which is a semiconductor, is mixed with hydroxide and increases the specific conductivity of the powder. Increased electrical conductivity has a positive effect on charge effectiveness, because the initial phase has lower electrical conductivity than the oxidized form – NiOOH. Because the charge involves two processes – the main process of active material charging and evolution of molecular oxygen, the electrical conductivity would play a key role in the electrode charging. At low electrical conductivity and fast charge, the current would primarily be consumed by the side process of oxygen evolution. In case of slow charges, additional electrical conductivity due to the presence of silver oxide would not have a great effect on charge effectiveness, because under such conditions the own conductivity of hydroxide is sufficient. Additionally, the presence of silver oxide would decrease the hydroxide content, which in turn would decrease the utilization coefficient that is calculated from the total mass of the powder.
Sinking Slab Stress and Seismo‐Tectonics of the Indo‐Burmese Arc: A Reappraisal

Differing views on the north‐eastern Indian plate subduction and its seismic potential place the subduction process as relict, ceased, creeping, or fully locked, challenging the seismic hazard uncertainty estimates of Indo‐Burmese Arc (IBA) at either extreme. To clear some of these contentions, we re‐examine the state of the IBA stress field using available earthquake faulting mechanism solutions. Our stress inversion results underline the tectonic complexity and emphasize that the stress of this subduction is primarily driven by the northward oblique motion of the Indian Plate. Models highlight the presence of the least compressive stresses as the margin‐normal component, all along the shallow sinking slab. Furthermore, solutions link the shallow strike‐slip earthquakes with the lateral slab shear due to oblique slip‐partitioning. Spatial variations in the Indian slab stress field indicate higher margin parallel compression at the Naga versus the Chin and Rakhine‐Arakan segments, implying resistance to the northward motion of India, illuminating the buttressing effects on the IBA. Models also depict active ∼ E‐W shortening across the Kabaw Fault. Inversion solutions bring out a higher compressional environment toward the south, along the Sagaing Fault. Finally, based on the overall stress field variations, we speculate that the Rakhine‐Bangladesh Megathrust could be a low‐stress forearc, as across the arc interacting stress fields are weak, capable of generating megathrust ruptures. Being weak, the stress replenishment times could be longer than the mechanically strong subduction zones. Due to the spatial stress field variations and buttressing effects, the interface may exhibit a variable rupture mode.

Glacial kettles as archives of early human settlement along the Northern Rocky Mountain Front

Abstract The Northern Rocky Mountain Front (hereafter Northern Front) is a prominent geographic feature in archaeological models of human dispersal in the terminal Pleistocene and Early Holocene of North America. Testing those models has been arduous because of local geomorphological factors that tend to obliterate or otherwise limit access to archaeological finds of relevant age. In this paper, we present well-stratified archaeological and environmental records dating back to 14,000–13,000 cal yr BP from the site of Billy Big Spring (Blackfeet Indian Reservation, Montana), located on a glacial kettle, a type of landform that has been largely ignored by regional archaeological research to date. Findings from Billy Big Spring show the continuous use of the Northern Front foothills throughout the major climatic and environmental disturbances of the Early Holocene, and possibly the terminal Pleistocene as well. As such, Billy Big Spring contributes to refining several archaeological models of early settlement of the Northern Front, particularly those that posit differential use of foothills versus plains settings during the midst of the Holocene Thermal Maximum. The record at Billy Big Spring also suggests that kettles, regardless of physiographic setting, provide a yet unsuspected and unsampled potential for preserving high-quality and easily accessible early archaeological and paleoenvironmental records.
Simulating the Capacity of Rainfed Food Crop Species to Meet Social Demands in Sudanian Savanna Agro-Ecologies

West African land use systems have been experiencing one of the fastest transformations in the world over recent decades. The Sudanian savanna is an interesting example, as it hosts the cultivation of some crops typical of the Guinean savanna as well as some of the Sahel. Therefore, this region is likely to experience further changes in its crop portfolio over the next decades due to crop migration processes responding to environmental change. Simulation approaches can guide the development of agricultural production strategies that contribute to sustainably optimize both food and fuel production. This study used crop models already available in the APSIM platform to simulate plant production and the soil water and nutrient cycles of plots cultivated with groundnut, millet, sorghum, maize, and rice on three (two upland and one lowland) soil fertility classes and subjected to five levels of management (conventional tillage without residue incorporated to the soil and nor fertilizer application; conventional tillage without residue incorporated to the soil and 5 kg N ha−1; conventional tillage with residue incorporated to the soil 20 kg N ha−1, and no-till herbicide treated with 50 and 100 kg N ha−1). Simulation outputs were contrasted against data reported in the literature and converted into nutritional, fuel and feed yields based on the qualities and uses of their different plant comparments. Groundnut yields outperformed all of the cereals across most growing conditions, nutritional and feed indicators. Maize and rice provided the highest caloric yields, with the least fertile growing conditions. Sorghum provided average to high caloric and iron yields across all of the treatments. Millet provided the highest iron yields and high fuel yields across most treatments. Some simulated treatments could not be compared against literature review data because of their absence in actual cropping systems and the lack of experimental data. Plant production was simulated with higher accuracy than the other components of the simulation. In particular, there is a need to better parameterize and validate the rice, groundnut and millet models under Sudanian savanna conditions in order to perform more accurate comparative assessments among species.
Consumption Pricing Mechanism of Scientific and Technological Resources Based on Multi-Agent Game Theory: An Interactive Analytical Model and Experimental Validation

SUMMARY In the context of Web 2.0, the interaction between users and resources is more and more frequent in the process of resource sharing and consumption. However, the current research on resource pricing mainly focuses on the attributes of the resource itself, and does not weigh the interests of the resource sharing participants. In order to deal with these problems, the pricing mechanism of resource-user interaction evaluation based on multi-agent game theory is established in this paper. Moreover, the user similarity, the evaluation bias based on link analysis and punishment of academic group cheating are also included in the model. Based on the data of 181 scholars and 509 articles from the Wanfang database, this paper conducts 5483 pricing experiments for 13 months, and the results show that this model is more e ﬀ ective than other pricing models - the pricing accuracy of resource resources is 94.2%, and the accuracy of user value evaluation is 96.4%. Besides, this model can intuitively show the relationship within users and within resources. The case study also exhibits that the user’s knowledge level is not positively correlated with his or her authority. Discovering and punishing academic group cheating is conducive to objectively evaluating researchers and resources. The pricing mechanism of scientiﬁc and technological resources and the users proposed in this paper is the premise of fair trade of scientiﬁc and technological resources.
Driving angle prediction of lane changes based on extremely randomized decision trees considering the harmonic potential field method

ABSTRACT A lane-changing process is complicated due to multiple factors in the driving environment, and unsafe lane-changing behaviour may lead to a severe crash. This study proposes a method for the driving angle prediction of lane changes based on extremely randomized decision trees. First, the harmonic potential is defined to characterize the interaction between the lane-changing vehicle and the surrounding vehicles. Next, we construct extremely randomized decision trees to predict driving angles considering relative velocity, relative acceleration, and potential as input variables. Then, the NGSIM dataset is used to verify the method proposed, and the lane-changing process is divided into two stages by different environments. Furthermore, a comparison of prediction performance with several traditional machine learning methods further demonstrates the superior learning ability of the proposed method. Finally, we conduct a sensitivity analysis on the significant variables and discuss the effects of these variables on the prediction results.
S2 Alar Iliac Screw and S1 Pedicle Screw Fixation for the Treatment of Sacral Fractures : A Finite Element Study

Background: Five different sacral fracture fixation methods were compared using finite element (FE) analysis to study their biomechanical characteristics.Methods: Denis type I sacral fractures were created by FE modeling. Five different fixation methods for the posterior pelvic ring were simulated: sacroiliac screw (SIS), lumbopelvic fixation (LPF), transiliac internal fixator (TIFI), S2-alar-iliac (S2AI) screw and S1 pedicle screw fixation (S2AI-S1), and S2AI screw and contralateral S1 pedicle screw fixation (S2AI-CS1). Four different loading methods were implemented in sequence to simulate the force in standing, flexion, right bending, and left twisting, respectively. Vertical stiffness, relative displacement, and change in relative displacement were recorded and analyzed.Results: As predicted by the FE model, the vertical stiffness of the five groups in descending order were S2AI-S1, SIS, S2AI-CS1, LPF, TIFI. In terms of relative displacement, S2AI-S1 and S2AI-CS1 groups displayed a smaller mean relative displacement, although the S2AI-CS1 group exhibited greater displacement in the upper sacrum than the S2AI-S1 group. The SIS group displayed a moderate mean relative displacement, although the displacement of the upper sacrum was smaller than that of the S2AI-CS1 group. The LPF and TIFI groups displayed larger mean relative displacements. In terms of change in relative displacement, the TIFI and LPF groups displayed the greatest fluctuations in their motion, while the SIS, S2AI-S1, and S2AI-CS1 groups displayed smaller fluctuations.Conclusion: Compared with SIS, unilateral LPF and TIFI, S2AI-S1 displayed the greatest biomechanical stability of the FE models and can be used as a new method for the treatment of sacral fractures. When the S1 pedicle screw insertion point on the affected side is damaged, S2AI-CS1 can be used as a good alternative to S2AI-S1.
Selenium clusters in Zn-glutamate MOF derived nitrogen-doped hierarchically radial-structured microporous carbon for advanced rechargeable Na–Se batteries

Sodium–selenium (Na–Se) batteries are a promising substitute for traditional Li-ion batteries due to their high theoretical volumetric capacity (∼3260 mA h cm−3). However, shuttle effects and large volume changes still limit their practical applications. Herein, we embed Se clusters in nitrogen-doped hierarchically radial-structured microporous carbon (N-HRMC) derived from a zinc-glutamate metal–organic framework (MOF) for advanced sodium storage. In this carbon-based composite, the micropores and the C–Se and C–O–Se bonds in N-HRMC effectively confine the Se clusters and Na2Se during the discharge–charge process. The nitrogen doping in N-HRMC strongly enhances the electrical conductivity of Se and chemical adsorption on Na2Se. In particular, density functional theory (DFT) calculations demonstrate that pyridinic-N atoms provide much more chemical adsorption of Na2Se than graphitic-N and pyrrolic-N atoms. Consequently, the cathode with Se clusters embedded in N-HRMC deliver a capacity of 612 mA h g−1 after 200 cycles at 0.2C, with cycling stability for >500 cycles and a capacity retention of ∼100% from the 20th cycle at 0.5C, representing one of the best reported results for Na–Se batteries. Our work here suggests that embedding Se clusters in nitrogen-doped hierarchically structured microporous carbon systems presents an attractive strategy to enhance the capacity and rate capability of Na–Se batteries.
