Lessons learnt from nursing home an d homecare managers’ experiences with using the SAFE-LEAD gui d e

Background : In the SAFE-LEAD intervention we implemented a research-based guide (paper- and web-version) for managers to support their quality improvement work. This paper explores managers’ experiences with the SAFE-LEAD guide, and key factors of relevance for sustainability. Methods : Four Norwegian nursing homes and four homecare services participated, and 36 workshops with managers working together with researchers on the guide were conducted. After the intervention, nine focus groups with managers were conducted. Systematic text condensation was used for analysis. Results : Managers perceived the guide as useful in their quality improvement work. It helped create a systematic approach and overviewof improvement activities. The guide supported collaborative reflections, awareness and fitted with their daily work. Most preferred the web-version, but technical adjustments were required to ease its use. Priori-tization, anchoring, super users, and local adjustments were key factors for sustainability. Conclusion: Key factors for successful implementationwereadapting the guide to the local context, accessto supporting learning tools, thorough anchoring, acknowledging its benefits, and prioritizing. Further implementation studies should take technological maturity, ongoing changes and reorganizations in the sector and units into account. Careful planning and timing of the intervention, involving all relevant stakeholders at an early stage, is important.
Amperometric Detection of Dopamine based on a Graphene Oxide/PEDOT:PSS Composite Electrode

Dopamine (DA) is a hormone and a neurotransmitter that plays many important roles within the brain and body. It is an organic compound in the catecholamines and phenethylamines groups. A considerable effort has been made since its discovery, and numerous techniques for DA detection have been developed. Graphene and its derivatives have great potential for the development of sensors and biosensors. Since it has excellent characteristics, such as good conductivity and a large surface area, a graphene-based biosensor is expected to have high sensitivity, selectivity, and long-term stability characteristics. Graphene oxide (GO) was synthesized using a chemical method through graphite oxidation. Graphene oxide/poly (3,4-ethylene-dioxythiophene):poly (4-styrenesulfonate) (GO/PEDOT:PSS) composite films were prepared using an electropolymerization method on the surface of the working electrode. The properties of this composite electrode were characterized by cyclic voltammetry (CV) and scanning electron microscopy (SEM). The performance of the composite film was evaluated using three-electrode systems that consisted of a glassy carbon electrode (GCE) modifying a composite film electrode as a working electrode, a platinum electrode as an auxiliary electrode, and Ag/AgCl as a reference electrode. The variation of the composite electrode was applied and evaluated to DA electrochemical sensing. The GO/PEDOT:PSS-modified electrode also exhibits high performance with a low detection limit of 1 μM. The results obtained have shown that GO/PEDOT:PSS/GCE composites are promising candidates for modifying electrode material used in electrochemical sensing.
High-Contrast Electrochromic Polymers from Alkyl-Derivatized Poly(3,4-ethylenedioxythiophenes)

The syntheses of two new derivatives of 3,4-ethylenedioxythiophene (EDOT), specifically 5-octyldioxeno[2,3-c]thiophene (EDOT-C8) (2) and 5-tetradecyldioxeno[2,3-c]thiophene (EDOT-C14) (3), and their polymers are reported in this paper. Cyclic voltammetry of 2 and 3 in 0.1 M TBAP/CH3CN show irreversible monomer oxidation peaks (Ep,m) at 0.89 and 0.93 V, respectively. Multiple scans yield electroactive and conducting polymer films on electrode surfaces. The PEDOT-C8 and PEDOT-C14 formed oxidize with relatively low peak potentials at −0.22 and −0.19 V, respectively, indicating the doped form of the polymer to be quite stable. Both PEDOT-C8 and PEDOT-C14 show two reduction processes with peaks at −0.18 and −0.16 V (Ec2,p) and −0.55 and −0.36 V (Ec1,p) respectively. Optoelectrochemical studies reveal an Eg of 1.75 eV for both polymers. The polymers are electrochromic, relatively transmissive and light gray in the oxidized form, while being opaque and deep purple in the reduced form exhibiting high electrochrom.
Fatigue Characterization for Composite Materials used in Artificial Socket Prostheses with the Adding of Nanoparticles

The prostheses sockets use normally composite materials which means that their applications may be related with the human body. Therefore, it was very necessary to improve the mechanical properties of these materials. The prosthetic sockets are subjected to varying stresses in gait cycle scenario which may cause a fatigue damage. Therefore, it is necessary or this work to modify the fatigue behavior of the materials used for manufacturing the prostheses sockets. In this work, different Nano particle materials are used to modify the mechanical properties of the composite materials, and increase the fatigue strength. By using an experimental technique, the effect of using different volume fractions for various types for Nano particle materials on the fatigue behavior for composite materials, and preparing the fatigue samples and tested using the fatigue apparatus. The Nano particles used were (Nano SiO2 and Nano Al2O3) materials with volume fraction as (0% to 2%), for each type of Nano material used. The artificial neural network technique was adopted to have a verification for the experimental results and calculating the fatigue life and strength for composite materials, with the addition of nanoparticles and then, a comparison of the results was achieved. The comparison of the results indicate a maximum error between results calculated by two technique did not exceeded about (1%). Then, the results calculated showed that the mechanical properties and fatigue life and strength increase with reinforcement with Nano particle. Also, the results showed that the modified for fatigue limits with materials by (Nano SiO2) Nano particle was more than the modified for fatigue limits for materials reinforcement with other materials. Finally, it can be concluded that the modified for fatigue strength, by reinforcement with (Nano SiO2), leads to 60% more than fatigue limit without Nano additive.
Phlebotomus (Adlerius) simici NITZULESCU, 1931: first record in Austria and phylogenetic relationship with other Adlerius species

Background Phlebotomine sand flies are the principal vectors of Leishmania spp. (Kinetoplastida: Trypanosomatidae). Information on sand flies in Central Europe is scarce and, to date, in Austria, only Phlebotomus mascittii has been recorded. In 2018 and 2019, entomological surveys were conducted in Austria with the aim to further clarify sand fly distribution and species composition. Results In 2019, a Ph. simici specimen was trapped in Austria for the first time. Analyses of two commonly used marker genes, cytochrome c oxidase I ( cox I ) and cytochrome b ( cytb ), revealed high sequence identity with Ph. simici specimens from North Macedonia and Greece. Phylogenetic analyses showed high intraspecific distances within Ph. simici , thereby dividing this species into three lineages: one each from Europe, Turkey and Israel. Low interspecific distances between Ph. simici , Ph. brevis and an as yet unidentified Adlerius sp. from Turkey and Armenia highlight how challenging molecular identification within the Adlerius complex can be, even when standard marker genes are applied. Conclusion To our knowledge, this study reports the first finding of Ph. simici in Austria, representing the northernmost recording of this species to date. Moreover, it reveals valuable insights into the phylogenetic relationships among species within the subgenus Adlerius . Phlebotomus simici is a suspected vector of L. infantum and therefore of medical and veterinary importance. Potential sand fly expansion in Central Europe due to climatic change and the increasing import of Leishmania -infected dogs from endemic areas support the need for further studies on sand fly distribution in Austria and Central Europe in general.

Optimization Of Extraction Conditions For Andrographolide Using Fractional Factorial Design

Andrographolide is a major bioctive compound found in king of bitter ( Andrographis paniculata ). In this study, the extraction method and its condition were investigated in order to get an extract with maximum amount of andrographolide by comparing three other extraction methods, i.e. maceration, soxhletation and ultrasonication and also determination for the optimum condition of the selected extraction method. The highest andrographolide amount was found by maceration, so this method was choosen for further optimization of extraction condition. The optimum condition based on the prediction amount from 27 factor combinations was obtained in 360 times of extraction time, 2g/100mL of sample to solvent ratio, and 3fold of extraction frequency with prediction of andrographolide amount was 3.50%. While by using prediction profile, the optimum condition was obtained in 360min of extraction time, 2 g/100mL of sample and solvent ratio, and 4 times of extraction frequency with the amount was 3.47-3.74%.
Rich on Paper? Chinese Firms’ Academic Publications, Patents, and Market Value

By combining various databases of academic publications and patents of China’s publicly listed firms, we explore the effects of academic publications on firm values and possible mechanisms. We find that Chinese firms’ academic publications are positively associated with their market valuation; more importantly, such a positive relation is more pronounced when these firms have stronger patent records, highlighting a synergy between basic research and applied technologies. Mechanism tests indicate that firm’s academic publications promote their market values through enhancing their human capital and sending credible signals to professional investors and the general public. Additional tests show that publications in English-language journals are more value-relevant than in Chinese-language journals.
The Influence of Fence on Body Mass and Population Dynamics of Plateau Pika

To determine the influence of the fence on plateau pika (Ochotona curzoniae), we measured the body mass, breeding status, population densities, using live-trapping and line-transect sampling in April and September 2006. In April, body mass of both male and female plateau pika inside of fence were significant higher than that outside of fence (♀: F = 6.583, df = 1.20, p = 0.019; ♂: F = 6.49, df = 1.17, p = 0.021). The ratio of spermary drop of an adult male was also higher (92.31% vs 57.14%). In September, body mass of adult male in both study sites showed no significant difference (F = 0.001, df = 1.23, p = 0.975), but were all significant higher than that of April (F = 121.713, df = 1.22, p df = 1.20, p df = 1.38, p = 0.131), but the population density inside of fence was much higher than that outside of fence (F = 7.534, df = 1.38, p = 0.009) in September. Our results show that the changes of quality and quantity of food that available to plateau pika in winter, can depress the range of reducing body mass of plateau pika, make breeding season ahead, and then promote the increase of population.
A simple completion of Fisher’s fundamental theorem of natural selection

Abstract Fisher's fundamental theorem of natural selection shows that the part of the rate of change of mean fitness that is due to natural selection equals the additive genetic variance in fitness. Fisher embedded this result in a model of total fitness, adding terms for deterioration of the environment and density dependence. Here, a quantitative genetic version of this neglected model is derived that relaxes its assumptions that the additive genetic variance in fitness and the rate of deterioration of the environment do not change over time, allows population size to vary, and includes an input of mutational variance. The resulting formula for total rate of change in mean fitness contains two terms more than Fisher's original, representing the effects of stabilizing selection, on the one hand, and of mutational variance, on the other, making clear for the first time that the fundamental theorem deals only with natural selection that is directional (as opposed to stabilizing) on the underlying traits. In this model, the total (rather than just the additive) genetic variance increases mean fitness. The unstructured population allows an explanation of Fisher's concept of fitness as simply birth rate minus mortality rate, and building up to the definition in structured populations.
Epidemiological Profile of Male Infertility in Two Hospitals of Douala: A Cross-Sectional Study in a Sub-Saharan Africa Setting

Background: Male infertility is defined as a lack of pregnancy for a couple after 12 months of regular and normal sexual intercourse without contraception with the cause being clearly from the male origin. Contrary to popular belief, the prevalence of male infertility is similar to that of female infertility and sometimes even higher. However, data on the subject in Cameron are scarce and nonexistent in the city of Douala. This motivated the realization of this study in two centers in the city of Douala. The objective was to describe the epidemiological profile of male infertility. Methods: We conducted a cross-sectional study among patients who consulted for infertility in two hospital centers in Douala from January 2014 to October 2019. A consecutive sample of all eligible cases was considered for this study. Data were analyzed using Statistical Package for Social Sciences (SPSS Inc, Chicago, Illinois, USA) V. 20.0 and EPI-INFO V. 3.5 software. Analyzed variables included sociodemographic data (age, marital status, educational level, profession, region, alcohol, smoking habit and mean infertility duration) and other causes of infertility (obesity, history of testes infection, STI, testes traumatism, varicocele or varicocele surgery, herniorrhaphy, genetic or malformative disease). Results: We included 137 patients' records. The frequency of male infertility for patients consulting in urology was 5.6%. Their average age was 35.4±7.4 years. The average number of sexual intercourses per week was 2.7±0.97. Those patients were mainly from an intellectual profession (40.2%), married (71.5%) with a higher education level (67.2%). Almost 60% of the studied population had alcohol consumption. Primary infertility accounted for 65.7% of the study population and the average duration of infertility was 5.9±5.3 years. The main factors for infertility were respectively history of sexually transmitted infections (STI) in 59 (43.1%) and childhood mumps in 42 (32.7%) cases. Furthermore, herniorrhaphy (16.1%) and varicocelectomy (10.9%) were the most representative surgical background. Conclusion: Male infertility is not uncommon in urological consultation with primary infertility been more frequent. Risk factors of infertility in our setting included a history of STI, mumps, and surgery.
Thermal Stable Cetyltrimethylammonium−Magadiites: Influence of the Surfactant Solution Type

The reaction of protonated magadiite with the cationic surfactant cetyltrimethylammonium (C16TMA) was studied using different C16TMA solutions. The intercalation was achieved from C16TMAOH solution. However, only adsorption of C16TMA cations occurred on the external silicate surfaces from C16TMABr and C16TMACl solutions. Higher pH values were necessary to intercalate C16TMA cations from the bromide or chloride solutions. The intercalated C16TMA cations exhibited good stability in water and in basic (NaOH) solution, which was not the case in acidic (HCl) solution. Raman spectroscopy indicated that the intercalated C16TMA cations exhibited mainly trans conformation similar to the solid C16TMABr with additional gauche conformation. The decomposition temperature of intercalated C16TMA cations occurred at lower temperatures compared to pure C16TMABr. In situ Raman spectroscopy and X-ray diffraction at high temperatures were used to study the thermal stability of the organomagadiites and possible change in conf.
Knowledge-Sharing Enablers and Barriers in Research Centers: A Literature Review

The purpose of the study is to explore the enablers and barriers of knowledge-sharing and consider how knowledge-sharing is implemented by research centers. The literature review covers journals which are indexed (Scopus, ProQuest, and Thomson Reuters) and specialized in knowledge-sharing in research centers. The papers could be easily explored using the key search terms via search engines such as Google Scholar, Emerald Insight, and ProQuest. The review process included the studies from 1994 to 2018. Key search terms include “knowledge management”, “knowledge sharing”, “knowledge sharing enablers and barriers”, and “research centers” to reduce interpretation bias. Individual enabler factors supporting knowledge-sharing consist of social relations and networks, physical proximity to colleagues, a ‘no stupid questions’ culture, monetary rewards, trust, openness in communication, interactive communication, and intrinsic motivational factors. Meanwhile organisational factors include the provision of meeting facilities and informal spaces, appreciation of research by firms and society, diffusion and routine dissemination, simplification of the patenting process, organizational rewards, organizational culture, intention to knowledge sharing methods, extrinsic motivation factors, and others (teamwork, and solid research team). The study was approached from a theoretical perspective and the model proposed can be empirically validated by identifying statements for each dimension. Future research should explore more empirical studies from different countries especially case studies in research centers.
The Effect of Direct Versus Indirect Focused Written Corrective Feedback on Developing EFL Learners’ Written and Oral Skills

There has been an increasing attention to written corrective feedback (WCF) and its potential effectiveness in recent years. This paper examines the roles of direct versus indirect WCF in fostering learners’ written and oral accuracy across language proficiency. A quasi-experimental design was adopted to conduct the study. Seventy-six pre-intermediate and upper-intermediate EFL learners were randomly assigned into six groups (four experimental and two control groups). In the experimental group, a series of pictures were used as prompts for writing tasks in the treatment sessions, and pre-, immediate, and delayed posttests were used to measure written and oral accuracy. According to the results, WCF, regardless of the type, was facilitative in developing learners’ both written and oral accuracy, which was a manifestation of implicit knowledge. The results also revealed that the proficiency level played a key role in determining which type of CF was more beneficial. While the pre-intermediate learners benefited more from direct CF, the upper-intermediate group improved more as a result of indirect CF treatment. This study calls for more informed decisions by L2 teachers in the correction of written errors considering that it improved L2 learners’ oral accuracy.

Electronic properties of poly(vinylidene fluoride): a density functional theory study

We present a theoretical study of the piezoelectric polymer poly(vinylidene fluoride), PVDF. By density functional theory calculations, some of the distinct properties of this material have been obtained. Among such properties are hardness, capacitance, dipolar moment and energy associated with the conformational structural changes. For the calculations, we employed the B3LYP functional and the 6311+G(d,p) basis set. Five chain molecules of varying length were studied, H–(CH2–CF2) x –H, where x = 1–4 and 6 for the four different PVDF conformations, namely, I = Tp, II = TGa, III = TGp and IV = T3G, where T means trans and G means gauche.
The vacancy formation enthalpy in Ni determined by positron annihilation

The monovacancy formation enthalpy, H1vF, was determined for Ni using the Doppler broadening technique. The 58Co positron source was ion implanted in Ni of 99.995 wt. % purity. A 103Ru gamma -ray line (497 keV) was recorded simultaneously with the positron annihilation 511 keV line, and was used in stabilising the data. Measurements were performed on three similar Ni samples, which were annealed in an ultra-high vacuum chamber (10-8-10-9 Torr) at approximately 30 degrees C below their melting point for at least two hours prior to the in situ measurements. For one of the samples, a comparison was made of H1vF values deduced prior to and after in situ melting. A value of H1vF=1.8+or-0.1 eV was determined from the present data. In addition, a value for the monovacancy migration enthalpy, H1vM=1.1+or-0.1 eV, has been deduced from a comparison of the present H1vF measurement with previous self-diffusion results.
Macao College Freshman Students’ Beliefs and Intentions regarding Learning English as a Foreign Language (EFL): A Theory of Planned Behaviour Perspective

This paper investigated Macao college freshman students’ English learning under the framework of the Theory of Planned Behaviour (TPB), and a total of 544 valid questionnaire responses were collected for the analyses. Factors like attitudes towards English learning, subjective norms, and perceived behaviour control of Macao college freshmen were analysed with varimax rotation using Principal Component methods. Gender and previous learning places have a significant difference in those factors and their learning intention. The findings showed that the TPB explained Macao college freshman students’ English learning beliefs and attitudes. This study provides valuable implications for ways to increase student attitude. English instructors should understand freshman students’ English learning intention and adopt efficient teaching methods to increase their motivation.
