Published: December 2020

Background
Observational studies suggest that low 25-hydroxyvitamin D status is common and has been associated with higher mortality in critically ill patients. This study aim to investigate whether vitamin D supplementation is associated with lower mortality in critically ill patients.

Method
We searched Medline, Embase, and Cochrane databases from inception to January 12, 2020, without language restrictions, for randomized controlled trials comparing the effect of vitamin D supplementation with placebo in critically ill patients. Two authors independently performed data extraction and assessed study quality. The primary outcome was all-cause mortality at the longest follow-up.

Result
We identified nine trials with a total of 2066 patients. Vitamin D supplementation was not associated with reduced all-cause mortality at the longest follow-up (RR 0.90, 95% CI 0.74 to 1.09, I2 = 20%), at 30 days (RR 0.81, 95% CI 0.56 to 1.15), at 90 days (RR 1.15, 95% CI 0.92 to 1.44), and at 180 days (RR 0.82, 95% CI 0.65 to 1.03). Results were similar in the sensitivity analysis. The sample size met the optimum size in trial sequential analysis. Similarly, supplemental vitamin D was not associated with length of ICU stay, hospital stay, or mechanical ventilation.

Conclusion
Vitamin D supplement was not associated with reduced all-cause mortality in critically ill patients.

Published: December 2020

Context: This article presents the arguments that su­pport the formulation of a research model from the idea of “guided models,” which allows the designing of routes and methodologies for the approaching, formulating, and solving problems in the training of technologists and engineers.
Method: The methodology used was based on groun­ded theory, which allows solving problems and de­velop innovative research through theoretical and methodological categories.
Results: It was possible to organize the model with a special emphasis on the generation of monitoring and contrasting matrices as a control mechanism and guide for the researcher.
Conclusions: The implications of the incorporation of this model are analyzed in relation to the training purposes of engineering and technology professio­nals, articulated through a progression hypothesis as a reference every researcher will be able to get when analyzing and reviewing their own research processes regardless of the methodology developed.

Authors: Karnjuš Igor , Prosen Mirko , Krivičić Boško , Ličen Sabina 
Published: December 2020

Introduction: Student mobility programmes have become a valuable instrument in student education as they enable the acquisition of essential knowledge, skills and attitudes, and equip the individual more effectively to work in the globalised world. The aim of the study was to examine the impact of international exchange programmes on the personal and professional development of undergraduate nursing students.Methods: A quantitative secondary analysis was conducted. The primary data were collected in 2016 as part of the study entitled International Nursing Student Exchange – Comparison Between Slovene and Foreign Students. The sample in the secondary analysis consisted of 73 nursing students from Slovenia and other European countries. The questionnaire included 20 statements which were rated on a 5-point Likert scale (1-strongly disagree to 5-strongly agree). The data were described on the basis of calculated mean values and the Mann-Whitney U test.Results: On the personal level, students stressed that mobility can improve their self-confidence (Z = –2.088, p = 0.037) and acceptance of other cultures (Z = –3.116, p = 0.002). On the professional level, they highlighted the need to upgrade students' professional competencies (Z = –3.116, p = 0.002), particularly in the field of culturally competent nursing care (Z = –2.391, p = 0.017).Discussion and conclusion: The benefits reported by nursing students seem to show that it is sensible to continue to support and promote international student mobility programmes.
The operating mechanisms of self-efficacy and peer feedback: An exploration of L2 young writers
Authors: Kong Amy , Teng Mark Feng 
Published: December 2020

Abstract
There is a huge scarcity of documentation of instances in which students do not follow the peer review training guidelines. One factor in these unanticipated scenarios could be learners’ self-efficacy (SE). The current investigation illustrates how different sources of SE contribute to students’ agentic orientations during peer review. For this purpose, six secondary-one students were paired to implement peer reviews in an after-school English writing course, after receiving peer review training. The data from three dyadic peer review sessions, stimulated recalls, and pre-/post-interviews were triangulated with quantitative data from 20 learners. The results showed that the students’ low SE for self-regulation (SESR) for peer review at the outset overshadowed the impact of training and influenced the use of strategies by them during the peer reviews. Whereas those with high SESR followed the instructions from the training session and regulated the peer reviews professionally, those with low SESR ignored these guidelines, which resulted in constrained agency and promoted their skepticism of peer review in the end. However, by comparing their own performances as reviewers with those of their peers, the students’ SE for regulating future peer review also changed. This paper underscores SE as an important construct in peer review for L2 young learners.
Endogenous Peer Group Effects on Adolescents’ Crime Reporting Intentions
Authors: Agee Mark D. 
Published: December 2020

Abstract
This paper provides an empirical analysis of the determinants of adolescents’ crime reporting intentions with particular emphasis on the role of social interactions. The empirical strategy extends the discrete choice random utility model to allow preferences to be defined over the expected actions of an individual’s peer group defined by his or her class at school. In this context, students choose whether to report instances of bullying, property theft, or academic cheating they may witness at or around school. Both endogenous and exogenous peer group effects on adolescents’ crime reporting intentions are identified and estimated using a 1620-student dataset. Results lend support to the hypothesis that social interactions play a significant role in shaping adolescents’ decisions to report wrongdoing they may witness. These group influences can strengthen, or temper school policies aimed at encouraging students to take a more active role in reducing school or community crime.

Abstract
The marine shale in southern China has undergone complex tectonic evolution with a high thermal evolution degree. Excessive thermal evolution brings certain risks to shale gas exploration and development. With the advancement of experimental methods, the evolution process of shale reservoirs can be better understood from the micro-nanoscale. This work takes the Ordovician-Silurian Wufeng and the first member of Longmaxi Formation in the Sichuan Basin and Lower Cambrian Niutitang Formation in Outer Margin of the Sichuan Basin to study the impact of maturity upon the genesis of shale gas and development features of the reservoir. A series of geochemical research methods, including TOC, gas component and gas isotope, were adopted to study the impact of different thermal evolution stages of organic matter upon the genesis of shale gas. The nanoscale micro-imaging technique, such as FIB-SEM and FIB-HIM, was used to analyze the development of OM-hosted pores. As shown from the results, when R
o = 1.2–3.5%, the marine shale gas is dominated by methane and other hydrocarbon gases, since the mixture of cracking gas from liquid hydrocarbons and kerogen-cracking gas cause the carbon isotope reversal. Besides, the pyrobitumen pores characterized by the strong connectivity and storage capacity were primarily developed. When R
o > 3.5%, the organic matter is at the graphitization stage. The shale gas is mainly composed of nitrogen at this stage. The nitrogen is originated from the atmosphere and the thermal evolution process, and the OM-hosted pores (pyrobitumen and kerogen pores) characterized by the bad connectivity and storage capacity are developed. Finally, the main component of shale gas, the genesis of shale gas and the pattern of OM-hosted pores under different thermal evolution stages of organic matter are summarized, which provide technical support for the exploration and development of shale gas.
Inverse characterisation of gradient distribution of the modulus of bamboo using a four-point bending test
Authors: Gao Xianzhi , Liu Guangyan , Wang Lu , Yi Yanan , Lin Guang , Ma Shaopeng 
Published: December 2020

Abstract
As a natural graded material, bamboo has gradually increasing elastic modulus along the radial direction from the inner to the outer skin. Accurate measurement of the modulus distribution plays an important role in bamboo-based structural design. However, it is difficult to characterise this modulus distribution by using conventional testing approaches on bamboo slices. A more effective method was developed in this study for the inverse identification of gradually varying material properties. The method is based on the digital image correlation and finite element model updating techniques. The radial distribution of the elastic modulus of bamboo was obtained through only one four-point bending test. The inversely identified modulus distribution was verified through uniaxial tensile tests on sliced bamboo strips and microscopic observation of the volume fraction distribution of its vascular bundle. The results showed that the elastic modulus of the bamboo material decreased from the outer skin (20 GPa) to the inner skin (2 GPa), which is in good consistence with the tensile test results on sliced specimens.
Effect of Nb addition on the solidification structure of Fe–Mn–C–Al twin-induced plasticity steel
Authors: Du Wen-Hui , Li Chang-Rong , Zhuang Chang-Ling 
Published: December 2020

AbstractThe solidification microstructure of an Fe–Mn–C–Al high-Mn steel with added Nb was studied by optical microscopy and scanning electron microscopy. The results showed that the size of the columnar and equiaxed grains in the solidified structure of the high-Mn steel without added Nb was large. When Nb was added, the size of the equiaxed and columnar grains in the solidification structure of the high-Mn steel decreased. The twin-induced plasticity in the high-Mn steel with added Nb clearly refined the grain size of the solidified structure and simultaneously increased the equiaxed crystallization rate. The high-melting-point second-phase particles increased the heterogeneous nucleation rate, which was beneficial for grain refinement. A large amount of Nb precipitates from the solidification process increased the equiaxed crystallization rate of the solidified microstructure. The increased crystallization rate affected the growth direction of the columnar and equiaxed grains during solidification and indirectly decreased the probability of crack formation, which improved the quality of the twin-induced plastic steel.

Published: December 2020

Abstract
Adsorption as an air purification method is widely employed to remove volatile organic compounds with low concentration using zeolites. In this study, ZSM-5 and LSX zeolites modified by alkali metal cations (Li+, Na+ and K+) were used as adsorbents for the abatement of toluene. The adsorption behaviors of toluene onto adsorbents with different pore sizes and cation contents were evaluated systematically based on the experiments of adsorption equilibrium, kinetic diffusion and desorption. Besides, Langmuir and Freundlich model, constant-pattern wave propagation model and Kissinger method were applied to fit with the above experimental data. The adsorption amount followed the sequence of Li-LSX > Na-LSX > K-LSX > Li-ZSM-5 > Na-ZSM-5 > K-ZSM-5 obtained from equilibrium isotherms. LSX zeolites showed twice adsorption capacity on unit volume compared to ZSM-5. The mechanisms of steric hindrances and electrostatic interactions controlling the diffusion rate under high and low concentrations were proposed, respectively. At relatively low loadings of toluene, the diffusion resistances were primarily affected by electrostatic interaction due to preferential adsorption of toluene on cationic sites. While at relatively high loadings, the diffusion resistance was mainly restricted by steric effect because of saturated cationic sites. The strength of adsorbate-adsorbent interactions was assessed by temperature programmed desorption experiments. It showed that both adsorption sites and microporous walls contributed to the desorption energy.
Investigation on influences of loose gas on gas-solid flows in a circulating fluidized bed (CFB) reactor using full-loop numerical simulation
Authors: Huo Pengju , Li Xiaohong , Liu Yang , Qi Haiying 
Published: December 2020

Abstract
The influences of loose gas on gas-solid flows in a large-scale circulating fluidized bed (CFB) gasification reactor were investigated using full-loop numerical simulation. The two-fluid model was coupled with the QC-energy minimization in multi-scale theory (EMMS) gas-solid drag model to simulate the fluidization in the CFB reactor. Effects of the loose gas flow rate, Q, on the solid mass circulation rate and the cyclone separation efficiency were analyzed. The study found different effects depending on Q: First, the particles in the loop seal and the standpipe tended to become more densely packed with decreasing loose gas flow rate, leading to the reduction in the overall circulation rate. The minimum Q that can affect the solid mass circulation rate is about 2.5% of the fluidized gas flow rate. Second, the sealing gas capability of the particles is enhanced as the loose gas flow rate decreases, which reduces the gas leakage into the cyclones and improves their separation efficiency. The best loose gas flow rates are equal to 2.5% of the fluidized gas flow rate at the various supply positions. In addition, the cyclone separation efficiency is correlated with the gas leakage to predict the separation efficiency during industrial operation.
Spiritual Talk: Addressing Existential Themes in Interfaith Encounters
Authors: Liefbroer Anke I. , Olsman Erik 
Published: December 2020

Abstract
Spiritual caregivers increasingly care for clients with other religious/spiritual (R/S) orientations than their own. To date, the ways in which spiritual caregivers deal with these differences have hardly been explored. Based on an analysis of audio records of 34 spiritual caregiver-patient interactions, this paper describes communication techniques used by spiritual caregivers to address existential themes in conversations with patients with various R/S orientations. The model presented describes these techniques regarding the extent to which spiritual caregivers comply with the patient’s R/S orientation and disclose their own R/S orientation. This model can be used to analyze how spiritual caregivers interact with their clients.
Timothy: Preparing for The Holy Eucharist within the Community when Communication is Non-verbal
Authors: Cooreman-Guittin Talitha 
Published: December 2020

Abstract
Persons with intellectual disabilities are still regularly refused access to the Eucharist, as illustrated in an article in the Washington Post. Although Pope Francis and several Bishops’ Conferences and the new Directory for Catechesis (n°269–272) have made it clear that Catholics with disabilities have a right to participate in the sacraments as all other members of the ecclesial community, many church leaders still refrain from allowing persons with profound intellectual disabilities to access the Eucharist. This article investigates the experience of a pastoral team that prepared First Communion of a young boy with profound intellectual disabilities. The experience raised practical theological, pedagogical and pastoral ecclesial issues to be solved. These issues structure the article.
The left and right periphery in native and non-native speech – A comparative study between French L1/L2, Spanish L1/L2 and Swedish L1
Authors: Fant Lars , Bartning Inge , Österberg Rakel 
Published: December 2020

AbstractHigh-proficient Swedish users of L2 French and Spanish were compared with native speakers of French, Spanish and Swedish with regard to how the syntactic peripheries in natural colloquial speech are structured. Two different though interrelated aspects were included: thus a cross-linguistic analysis comparing the three native speaker groups is combined with an analysis addressing the question of the upper limits of L2 acquisition. All left peripheral (LP) and right peripheral (RP) constituents of a corpus of 110,759 words were classified in a taxonomy relying both on syntactic and functional-pragmatic criteria. The cross-linguistic analysis showed that French and Spanish L1 speakers produced significantly longer LP sequences than the Swedish L1 speakers, who, in turn, put conspicuously more weight on the RP. Significant differences between the three languages were also found with regard to several LP and RP constituent categories. The L2 acquisition-oriented analysis showed that with few exceptions the high-proficient L2 users behaved like L1 users. Although a few interlanguage-related phenomena could be observed, no instances of any clear transfer from the speaker’s L1 appeared in either L2 speaker group.

Abstract
This article addresses the issue of the profitability of Food Quality Scheme (FQS) products as compared to reference products, which are defined as analogous products without quality label. We approach this question by taking into account the level of the value chain (upstream, processing, and downstream), the sector (vegetal, animal, seafood) and the type of FQS (PGI, PDO, Organic). We collected original data for several products produced in selected European countries, as well as in Thailand and Vietnam. Comparisons depending on value chain level, sector and FQS are possible by using two comparable indicators: price premium and net price premium (including cost differential). The following principal conclusions were reached: 1) Price is higher for FQS products than for the reference products, regardless of the production level, the type of FQS or the sector; 2) Price premiums generated by FQS do not differ along the value chain, nor between sectors (vegetal, animal or seafood/fish); 3) Price premium for organic products is significantly higher than for PGI products, and this conclusion holds at upstream and processing levels, taking into account the costs directly related to production; 4) All organic products and almost all PDO and PGI products analysed benefit from a positive quality rent; 5) At upstream level and processing level, the relative weight of intermediate consumption in the cost structure is lower for organic products than for reference products.
Efficacy of expanded polystyrene as fine aggregate in cement mortars modified with latex paint as an alternative to polymer admixture

Published: December 2020

Abstract
In this present study, the effectiveness of expanded polystyrene (EPS) waste used as 20, 40 and 60% fine sand replacement in development of lightweight cement composite was evaluated. The cement mortar was strengthened by 10% low cost latex paint emulsion as an alternative to the more expensive polymer admixtures. Six different mix designs were produced and tested for compressive and split tensile strength according to BS EN standards. Scanning electron microscope (SEM) analysis was also conducted to analysis the micrograph of the samples. It was observed that as the EPS content, latex paint polymer admixture and curing days were increased, marginal increment in compressive strength was obtained. However, EPS fines were most effective in improving the split strength while latex paint admixture had comparatively less part to play in the strength development. The micrograph images showed that the EPS fines were uniformly distributed within the microstructure and the latex paint developed polymer films. These mechanisms coupled with the cement hydrate products were responsible for the enhanced strength observed in the samples.
