Dry-Hop Creep Potential of Various Saccharomyces Yeast Species and Strains

Previous research has shown that hops contain enzymes able to hydrolyze unfermentable dextrins into fermentable sugars when added during the dry-hopping process. In the presence of live yeast, these additional fermentable sugars can lead to an over-attenuation of the beer; a phenomenon known as “hop creep”. This study attempts to analyze the effect of different Saccharomyces yeast species and strains on hop creep, with the intent to find an ability to mitigate the effects of dry-hop creep by using a specific yeast. Thirty different yeast species and strains were chosen from commercial and academic collections and propagated for pilot fermentations. Brews were performed at the Anheuser-Busch Research Brewery (1.8 hL, 10 °P, 20 IBU) at UC Davis and split to 40 L cylindroconical fermenters, with one fermenter in each yeast pair receiving 10 g/L Centennial hop pellets towards the end of fermentation. Standard analytical measurements were performed over the course of fermentation, with real degrees of fermentation (RDF) and extract measured on an Anton Paar alcolyzer. In order to preemptively determine the amount of hop creep to be experienced with each unknown fermentation, bench-top fermentations with 20 g/L dry-hops were performed concurrently and compared to the pilot scale fermentations. RDF was significantly higher (p < 0.01) on dry-hopped than non-dry-hopped fermentations beginning two days post dry-hopping to the end of fermentation, with the exceptions of SafAle™ BE-134, a S. cerevisiae var. diastaticus, and UCDFST 11-510, a S. mikatae. No apparent correlation between flocculation and increased RDF was shown in dry-hopped treatments. pH was significantly different between the dry-hopped and non-hopped fermentations (p < 0.05 one day post dry-hop, p < 0.01 for all subsequent days); this may have impacted on additional attenuation. No yeasts in this study indicated their use for mitigation of dry-hop creep, but this is a first look at beer fermentation for some of the chosen yeasts. The results also present a new perspective on how hop creep varies in fermentation.

“Involved Is an Interesting Word”: An Empirical Case for Redefining School-Based Parental Involvement as Parental Efficacy

School-based parental involvement is a common practice in the United States, and yet there is an emerging view that parents’ involvement in schools may have little if any academic benefit for their children. However, such conclusions are often based on narrowly construed survey questions, such as “Did you attend PTA in the past year? ”. In our study, we re-examine commonly used measurements of school-based parental involvement using 130 interviews with parents and administrators across three diverse elementary schools. We compare conventional survey measures of school-based parental involvement with our own qualitative assessments of parental efficacy. Notably, we find that highly efficacious parents employed a wide range of involvement strategies, undetected by some traditional metrics of involvement (i.e., attending PTA meetings). As expected, we also find that efficacious parents were largely advantaged themselves and concentrated in advantaged schools. However, school contexts can play a powerful role in shaping the reception of parents’ engagement with schools—the presence of a Spanish immersion program transformed how teachers and administrators interpreted the involvement activities of Latinx parents. Our results point to the importance of (1) recasting parental involvement as parental efficacy and (2) integrating school contexts to understand how efficacy can be more effectively encouraged and deployed.
Health Risk Assessment of Cadmium and Mercury via Seafood Consumption in Coastal Area of Nai Thung, Nakhon Si Thammarat Province, Thailand

Metal contamination in seafood may cause adverse effects on human health. The objectives of this study were to determine the concentrations of cadmium and mercury in seafood from the coastal area of Nai Thung sub-district, Nakhon Si Thammarat Province, Thailand, and to evaluate the potential health risk of seafood consumption. A total of 46 samples (including 26 species of fish and shellfish) were caught in March and July 2018. Results indicated that the concentrations of metals in seafood samples were within the standards established for human consumption. However, cadmium concentrations in most shellfish samples were higher than the fish samples, and mercury in fish was higher than other marine organisms. The health risk assessment (HRA) of cadmium and mercury in seafood consumption was between 0.0004 - 0.07 and 0.001 - 0.035, respectively. The results showed that seafood from Nai Thung was unlikely to affect human health.
PRICING AMERICAN OPTIONS WITH THE RUNGE–KUTTA–LEGENDRE FINITE DIFFERENCE SCHEME

This paper presents the Runge-Kutta-Legendre finite difference scheme, allowing for an additional shift in its polynomial representation. A short presentation of the stability region, comparatively to the Runge-Kutta-Chebyshev scheme follows. We then explore the problem of pricing American options with the Runge-Kutta-Legendre scheme under the one factor Black-Scholes and the two factor Heston stochastic volatility models, as well as the pricing of butterfly spread and digital options under the uncertain volatility model, where a Hamilton-Jacobi-Bellman partial differential equation needs to be solved. We explore the order of convergence in these problems, as well as the option greeks stability, compared to the literature and popular schemes such as Crank-Nicolson, with Rannacher time-stepping.
How robust is the evidence for beneficial hydrological effects of urban tree planting?

ABSTRACT Sustainable urban water management initiatives are increasingly required to combat rapid urbanization and climate pressures. Initiatives include the role of tree planting, for which there is a need for strong evidence of benefits and drawbacks to support effective future planning. We report on the robustness of evidence from an assimilated database of urban hydrological impact studies which often had differing primary purposes. Consistent impacts were found at the local level, with trees reducing runoff and infiltration. Despite the consistency of evidence, much is undermined by the studies being somewhat lacking in robustness and scientific rigour. Many studies lack adequate controls, and models are often not strongly tested against observations. Moreover, evidence of impact at larger scales is lacking. Effects of tree characteristics were also investigated, such as maturity and species (for which evidence is consistent and detailed) and arrangement (for which there is less evidence). Realizing the full potential of trees in urban water management decision-making would benefit from more rigorous evidence.
Board characteristics, auditing characteristics and audit report lag in African Central Banks

PurposeThe purpose of this paper is to examine the determinants of audit report lag in Sub-Saharan African Central Banks. In this case, the determinants were divided into two categories: independent variables and mediating variables. The independent variables, which were generated from board characteristics, included board size, board gender diversity, governor duality, audit committee size and audit committee meetings. The mediating variables were auditing characteristics and they comprised audit mandate, audit approach and audit quality.Design/methodology/approachThe study used data from 192 observations from African Central Banks' financial reports for the period 2000–2016. The data collected were analyzed using path analysis, whereby four regression models were run and tested simultaneously. From the analysis, the study determined total effects and then decomposed the total effects into direct and indirect effects.FindingsThe study results indicate that in the case of board characteristics, governor duality and audit committee size were found to have a positive influence on audit report lag. In the case of audit quality, only audit mandate was found to have a negative influence on audit quality in the Central Banks. However, the introduction of mediating variables increased the positive effect of governor duality and audit committee size, while also making board size and board gender diversity have a significant negative effect on audit report lag.Practical implicationsThe findings of this paper have implications for the practice and policy of the auditing and governance of Central Banks, which includes designing appropriate governance structures as well as proper auditing strategies.Originality/valueThis is the first study which has examined factors influencing audit report lag in Central Banks. Previous studies on Central Banks' governance have examined the independence and autonomy of the Central Banks, as well as their accounting. This paper extends prior studies by examining the effects of those factors. Another contribution is the study's application of auditing characteristics as mediating variables.
R&D Intensity and Its Curvilinear Relationship with Firm Profitability: Perspective from the Alternative Energy Sector

There is an inconclusive debate concerning the relationship between environmental research and development (R&D) and corporate financial performance (CFP). The debate becomes more complex because a win–win situation between environmental and financial goals is not as plausible in practice as it is in theory. Though arguments have been made that when time-lag is considered, the relationship can produce positive outcomes for both entities, ambiguities persist because linear models dominate this analysis. This study, therefore, empirically tested the existence of a curvilinear relationship between R&D intensity and CFP in the context of the alternative energy sector. Using a panel dataset of 24 companies and 232 unbalanced firm-year observations for 10 years, it was found that after passing the inflection points, investment in R&D reaps financial benefits that will eventually offset the cost of the initial investment. The curvilinear relationship of R&D intensity on return on sales and net profit margin is strongly supported.
The Synthesis of CuS Hexagonal Nanosheet-Graphene for Use as a High Performance Photocatalyst

CuS hexagonal nanosheet/graphene was fabricated by a facile one-pot microwave-thermal method. The samples possess excellent photocatalytic activity for degradation of organic pollutant under visible light. The high photocatalytic activity was attributed to the deposition of CuS hexagonal nanosheet onto graphene. CuS nanosheet serves as a transporter which efficiently inhibits the recombination of the photo-induced charge carriers in the nanocomposites. The developed method demonstrates a facile approach towards the synthesis of two-dimensional semiconductor-graphene nanocomposites with excellent photocatalytic performance under visible light.
Migration Groups: A Poorly Explored Point of View for Genetic Damage Assessment Using Comet Assay in Human Lymphocytes

A new point of view for genetic damage assessment using the comet assay is proposed based on the number of migration groups, the number of comets in each group, and the groups with the highest number of comets. Human lymphocytes were exposed to different concentrations of Methyl Methane Sulfonate (MMS), Maleic Hydrazide (MH), 2,4-Dichlorophenoxyacetic (2,4-D), and N-nitroso diethylamine (NDEA). Using comet assay, the migration means of the comets were determined and later grouped arbitrarily in migration groups with no higher differences than 1 µc. The number of migration groups, the number of comets in each group, and the groups with the highest number of comets (modes) were determined. All four of the genotoxic agents studied showed a significant increase (p < 0.05) in the tail length and the number of migration groups compared to the negative control. The number of migration groups did not show a significant variation between the four-genotoxic agents nor within their different concentrations. However, the comparison of the modes did show differences between the genotoxic agents, but not within the concentrations of a same genotoxic agent, which indicated a determined chemical interaction on the DNA. These parameters can improve the detection of genetic damage associated with certain genotoxic agents.
‘The green potion is the virus. The blue one is the corona test. The coloured one makes your wish come true’: Irish children’s changing perceptions of a scientist as a result of the onset of COVID-19

ABSTRACT This study explored the impact of the COVID-19 pandemic on primary school children’s perceptions of scientists. Perceptions of scientists were examined using Chambers, D. (1983. “Stereotypic Images of the Scientist: The Draw-a-Scientist Test.” Science Education 67 (2): 255–265) ‘Draw-A-Scientist Test’ (DAST) and involved children (n = 104), from senior infants and fourth class, making drawings of scientists. Half the drawings were created in March 2020 one week before school closure due to the COVID-19 pandemic and the remainder in November 2020 when schools reopened. Compared to pre-pandemic drawings, images created during the pandemic revealed more informed understandings of scientists and their work and fewer drawings were classed as ‘uncategorised’. However, drawings made during the pandemic revealed more stereotypical perceptions of scientists and their work as indicated by the larger number of stereotypical indicators incorporated into drawings. These increases were statistically significant for younger children. A welcome finding was broader conceptions of the nature of a scientists’ work, a shift that appeared to be motivated by the context of the COVID-19 pandemic.
On the Relationship Between Non-alcoholic Fatty Liver Disease with Body Composition and Bone Mineral Density in Overweight/Obese Adolescents

Background: Nonalcoholic fatty liver disease (NAFLD) is a health problem growing in line with the rising prevalence of obesity in children and adolescents, which may be correlated with different metabolic abnormalities such as osteoporosis. Objectives: This study aimed to evaluate the possible relationship between NAFLD with body composition and bone mineral density (BMD) in obese and overweight adolescents. Methods: This cross-sectional study encompassed 70 adolescents aged 11 - 18 years and was conducted during March 2016 and September 2016 in Mashhad, Iran. Anthropometric parameters and blood biomarkers were measured. Fat mass, fat-free mass, and BMD were determined using dual-energy X‐ray absorptiometry (DXA) scans, and NAFLD was also assessed using Fibroscan. All statistical data were analyzed using SPSS software version 21. Multivariate linear regression assessed the relationship between liver fat content with bone-related indicators, and multivariate logistic regression detected the relationship between body composition and NAFLD. Results: Total and trunk fat mass were significantly correlated with higher NAFLD even after controlling for intervening factors (total fat mass, OR = 1.27; 95% CI, 1.016 to 1.59, P = 0.036; trunk fat mass, OR = 1.35; 95% CI, 0.97 to 1.88, P = 0.045). Moreover, liver fat content was significantly correlated with lower BMD Z-score after adjusting for gender, BMI Z-score, ALT, fat mass index, total lean mass, and physical activity (β = -0.285, P = 0.048). Conclusions: The findings of the present study suggest that excess adipose tissue is correlated with higher NAFLD. Moreover, liver steatosis may be correlated with decreased BMD Z-score in overweight/obese adolescents.
LIFE IN THE DIGITAL SLOW LANE: HOW DEPRIVED YOUNG PEOPLE ARE SET UP TO FAIL

ABSTRACT The phenomenon of digital differentiation, or stark variations in ability to access Internet hardware and/or infrastructure, has been a feature of provision since its early days. This article explores the impact of digital differentiation on two groups of young people, in England and Germany. It is based on fieldwork that took place during the academic year 2018-2019, just before the global pandemic threw the issue of equality of Internet access into sharp relief. The article begins by describing the empirical design of the My Life Online project, including background, sampling, instruments, ethical aspects and the initial data analysis approach taken to ensure reliability and validity. It then develops a further analysis drawing on Halford and Savage’s hybrid Bourdieu/Actor Network Theory model (2010) to map out the socio-technical network surrounding the young people in our study. In this way we identify areas of change and conflict that compound existing social deprivation. We conclude by making a case for a better education policy awareness of the key issues, and more equitable distribution of national infrastructure moving forwards.
Sleep duration and its relationship with school performance in Iranian adolescents

Summary Background Inadequate or poor sleep quality is common problems in adolescent that affect on their learning, memory and school performance. The present study aimed to determine the association between sleep hours and academic performance in young adults. Methods This cross-sectional study was designed as a descriptive-analytic study. Samples of adolescents of 14-18 years old in Qazvin city were enrolled. The Pediatric sleep questionnaire and BEARS questionnaire used for all students to screen comprehensively major sleeps problems in them. Chi-square test, t-test, analysis of variance (ANOVA), and correlation were performed to determine the relationship between the data (P < 0.001). Results Between 653 adolescents, 40% were male and 60% were female. Sleep duration, sleep onset delay, sleep insufficient, rate of oversleeping and academic performance had a direct relationship with gender (P < 0.001). The sleep duration, rate of oversleeping and academic performance were significantly higher in boys, sleep onset delay and sleep insufficient was significantly higher in girls. Time of falling sleep at weekend nights and weekday nights have positively correlation with age (P < 0.001). Also, a significant relationship between students’ sleep hours with academic performance was shown (P < 0.001). Conclusions The overall result was that sleep duration, sleep onset delay, sleep insufficient and rate of oversleeping of students in this study had a significant influence on academic performance. Students without difficulty in falling asleep had good academic performance in compared to students with difficulty in falling asleep.
The correlation between cognitive styles and written corrective feedback preferences among Iranian and Turkish EFL learners

This study aimed at finding the correlation between Iranian and Turkish EFL learners’ cognitive styles and their preferences for different WCF types. Sixty out of seventy-five EFL students at the intermediate level in two contexts (Iran and Turkey) were selected through the Oxford Placement Test. There were two instruments in this research: The Learning Styles Questionnaire, and CF questionnaire. The researcher gave detailed instructions on how to complete the surveys. The findings demonstrated that there was a correlation between EFL students’ cognitive styles and their WCF preferences in both Iran and Turkey contexts. The second research question results indicated that there was a relationship between learners’ cognitive styles and their preferences for different types of errors to be corrected. The results of the third research question showed that the correlation between Iranian students’ cognitive styles and their preferences for different CF frequencies was not significant. The last research question results showed that the correlation between Turkish students’ cognitive styles and their preferences for different CF frequencies was not significant. Keywords: Cognitive Styles – EFL Learners – Preferences – Written Corrective Feedback.
Selected ‘Starter Kit’ energy system modelling data for Congo Republic (#CCG)

Energy system modelling can be used to assess the implications of different scenarios and support improved policymaking. However, access to data is often a barrier to starting energy system modelling in developing countries, thereby causing delays. Therefore, this article provides data that can be used to create a simple zero order energy system model for Congo Republic, which can act as a starting point for further model development and scenario analysis. The data are collected entirely from publicly available and accessible sources, including the websites and databases of international organizations, journal articles, and existing modelling studies. This means that the dataset can be easily updated based on the latest available information or more detailed and accurate local data. These data were also used to calibrate a simple energy system model using the Open Source Energy Modelling System (OSeMOSYS) and two stylized scenarios (Fossil Future and Least Cost) for 2020-2050. The assumptions used and results of these scenarios are presented in the appendix as an illustrative example of what can be done with these data. This simple model can be adapted and further developed by in-country analysts and academics, providing a platform for future work.
