An Exploratory Study of Far Transfer: Understanding Writing Transfer from First-Year Composition to Engineering Writing-in-the Major Courses

This study aims to investigate how engineering undergraduates perform writing transfer from first-year composition (FYC) to engineering writing-in-the major courses. A sample of seventeen engineering students’ Junior Writing Portfolios, containing FYC research papers and engineering lab reports, was chosen for analysis in five broad rhetorical categories including invention, disciplinary knowledge, audience awareness, arrangement, and style. Informed by Yancey, Roberston, and Taczack’s 2014 study of writing transfer in composition courses, we grouped 17 engineering writing samples into three types of prior knowledge as identified in their study: remix, assemblage, and critical incidents. We found that the remix group students (n = 9) demonstrated an ability to integrate new engineering disciplinary knowledge into the schema of the old FYC knowledge. We observed a mixture of productive and unproductive transfer from FYC courses to engineering major courses with the assemblage group (n = 3). The critical incident students (n=5) struggled with multiple aspects of rhetorical principles, and they received the lowest scores in audience awareness and arrangement. Results from an accompanying focus group comprised of engineering students reported their perceptions of the similarities and distinctions between FYC assignments and engineering lab reports. These combined results suggest that students developed an understanding that genre features are genre specific and informed by disciplinary contexts.
Chlorogenic Acid Isomers Isolated from Artemisia lavandulaefolia Exhibit Anti-Rosacea Effects In Vitro

Rosacea is a chronic inflammatory disease affecting facial skin. It is associated with immune and vascular dysfunction mediated via increased expression and activity of cathelicidin and kallikrein 5 (KLK5), a serine protease of stratum corneum. Therefore, KLK5 inhibitors are considered as therapeutic agents for improving the underlying pathophysiology and clinical manifestation of rosacea. Here, we isolated the active constituents of Artemisia lavandulaefolia (A. lavandulaefolia) and investigated their inhibitory effect on KLK5 protease activity. Using bioassay-guided isolation, two bioactive compounds including chlorogenic acid isomers, 3,5-dicaffeoylquinic acid (isochlorogenic acid A) (1), and 4,5-dicaffeoylquinic acid (isochlorogenic acid C) (2) were isolated from A. lavandulaefolia. In this study, we evaluated the effects of isochlorogenic acids A and C on dysregulation of vascular and immune responses to rosacea, and elucidated their molecular mechanisms of action. The two chlorogenic acid isomers inhibit KLK5 protease activity, leading to reduced conversion of inactive cathelicidin into active LL-37. This inhibition of LL-37 production by isochlorogenic acids A and C reveals the efficacy of suppressing the expression of inflammatory mediators induced by LL-37 in immune cells such as macrophages and mast cells. In addition, both isomers of chlorogenic acid directly inhibited the proliferation and migration of vascular endothelial cells induced by LL-37.
Cascaded multilevel inverter using series connection of novel capacitor-based units with minimum switch count

This paper presents a new family of cascaded multilevel inverters (CMLIs) which can generate a considerable number of output voltage levels with minimum number of required accompanying switching devices. Conceptually, each stage of proposed CMLI is composed of using a novel capacitor-based unit including two floating capacitors, one embedded dc voltage source and three power switches. In this case, the balanced voltage of integrated capacitors can be precisely provided as self-voltage balancing without using any auxiliary circuits, close loop systems and intricate modulation techniques. In addition, to reach different number of output voltage levels, four different algorithms pertaining to the symmetrical, binary asymmetrical, trinary asymmetrical and also hybrid patterns for determining the magnitude of isolated dc voltage sources are presented. Hereby, proposed hybrid structure is capable of working under mixed switching frequency without aiming the conventional full H-Bridge cell. Therefore, a high quality of output waveforms with reduced switching devices as well as power loss dissipation can be alternatively achieved. To confirm the validity of proposed CMLI, a complete comparison with several recently presented topologies besides several simulation and experimental results based on trinary asymmetrical and hybrid evolved structures will be also given.
Enjoy Your Favourite Book as a Movie: Using an Experiential Learning Exercise to Improve Student Understanding of Brand Extensions and Marketing Plan Preparation

Marketers frequently use brand extensions to introduce new products and services. However, educators have limited resources to simulate the challenges of this strategy in classrooms. Using the scenario of a book being turned into a movie, we describe an experiential learning activity that guides students through the many stages of developing a brand extension. In this project, they also have the opportunity to put themselves in the shoes of a marketing manager in the preparation of a thorough plan for expanding an established brand to a new target market. The outcomes of its implementation in a marketing course, as well as the implications for marketing educators, are reviewed.
A New Neural Network Model for Prediction Next Stage of Alzheimer's Disease

: Alzheimer’s disease (AD) is a brain-related illness; The risk of development is minimized when diagnosed early. The early detection and treatment of Alzheimer’s disease are crucial since they can decrease disease progression, improve symptom management, allow patients to receive timely guidance and support, and save money on healthcare. Regrettably, much current research focuses on characterizing illness states in their current phases rather than forecasting disease development. Because Alzheimer’s disease generally progresses in phases over time, we believe that analyzing time-sequential data can help with disease prediction. Long short-term memory (LSTM) is a recurrent neural network that links previous input to the current task. A new Alzheimer’s Disease Random Forest (RF) LSTM Prediction Model (RFLSTM-PM) is proposed to capture the conditions between characteristics and the next stage of Alzheimer’s Disease after noticing that a patient’s data could be beneficial in predicting disease progression. Experiments reveal that our approach beats most existing models and can help with early-onset AD prediction. Furthermore, tests show that it can recognize disease-related brain regions across multiple data modalities (Magnetic resonance imaging (MRI), Neurological Test). Also, it showed decreased value in Mean Absolute Error and Root Mean Square Error for forecasting the progression of the disease.
Lecturers perception of contributory pension scheme implementation and job commitment in South-South Nigerian Universities

This study investigated lecturers’ perception of contributory pension scheme implementation and job commitment in South-South Nigerian universities. To guide the study, two research questions and one hypothesis were raised. A descriptive survey research that adopted correlational design. The population of the study was all the lecturers in the six federal universities in South-South Nigeria. The sample consisted of 579 lecturers in four selected universities established before the introduction of Contributory Pension Scheme. A multistage stratified random sampling was used in selecting the sample size of the study. Two research questionnaires were used for data collection, “Contributory pension scheme implementation Questionnaire (CPSIQ)’’ and “University Lecturers’ ob Commitment Questionnaire (UL CQ) . The reliability of the questionnaires were determined using Cronbach alpha statistics with values of . for CPSIQ and . for UL CQ respectively. The data collected were collated and analyzed with ean (x ) and standard deviation to answer the research questions while the Pearson Product Moment Correlation Statistic was used to test the hypothesis at 0.05 level of significance. The study revealed that the level of contributory pension scheme implementation as perceived by lecturers in South-South Nigerian Universities was low. It also revealed that the level of Job Commitment of University Lecturers in South-South Nigerian Universities was low; and that there was a significant relationship between Contributory Pension Implementation and Lecturers’ ob Commitment in South-South Nigerian Universities. The study therefore, recommended among others that government and university management should address the concerns of lecturers about the implementation of Contributory Pension Scheme in Nigerian Universities by ensuring prompt and regular remittance of deductions to lecturers’ Retirement Savings Accounts (RSA) so as to create confidence.
Joint Computation and Communication Resource Allocation With NOMA and OMA Offloading for Multi-Server Systems in F-RAN

Since mobile devices typically have limited computation resources, offloading computation tasks to fog access points (F-APs) is a promising approach to support delay-sensitive and computation-intensive applications. This paper considers joint computation and communication resource allocation for multiuser multi-server systems, which aims to maximize the number of users being served and minimize the total energy consumption subject to delay tolerance constraints. The joint computation and communication resource allocation problem is solved optimally for both non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) schemes. The joint user pairing and fog access point assignment problem for NOMA is proved to be NP-hard. For both NOMA and OMA, heuristic and optimal algorithms based on graph matching are designed. The optimal algorithms, though of high complexity, allow NOMA and OMA to be compared at their full potential and serve as benchmarks for evaluating the heuristic algorithms. Simulation results show that NOMA significantly outperforms OMA in terms of outage probability and energy consumption, especially for tight delay tolerance constraints and large computational tasks. Simulation results also demonstrate that our proposed NOMA and OMA schemes significantly outperform the swap-enabled matching algorithm widely used in the literature.
Making Sense of Consumer Inflation Expectations: The Role of Uncertainty

Consumers’ inflation expectations play a key role in the monetary transmission mechanism. As such, it is crucial for monetary policymakers to understand what they are and how they are formed. In this paper we introduce the (un)certainty channel as means to shed light on some of the more puzzling aspects of reported quantitative inflation perceptions and expectations. These include the apparent overestimation of inflation by consumers as well as the negative correlation observed between the economic outlook and inflation expectations. We also show that the uncertainty framework fits with some of the stylised facts of consumers’ inflation expectations, such as their correlation with socio-demographic characteristics and economic sentiment.

Impact of Cash Flow and Dividend Policy on Manufacturing Firm Value

A cash flow statement is a report showing how running, spending, and funding activities impact cash over an accounting period. In addition to cash flow, the dividend policy determines whether the company's earnings will be paid as dividends to investors or retained for reserve funds to support future investments. Firm value is the price a prospective buyer willing to pay if the business is sold. The research objective was to evaluate the impact of cash flow and dividend policies on firm value in Indonesian-listed manufacturing companies (BEI). The research tool used is multiple regression analysis techniques to evaluate the linear relationship between two or more independent variables and the dependent variable. The results showed a small effect of cash flow and dividend policies on firm valuation. Meanwhile, cash flow and dividend strategies have a strong and important effect on firm valuation.
Comment on gmd-2021-352

One goal of this paper is to convince the reader that the model can be used for scientific studies using a resolution of 16km. While many studies have shown this is too coarse to accurately represent ice sheet dynamic accurately, it can be a good trade off between computing cost and model accuracy especially for paleo time scale simulations. Keeping this in mind, I would have liked this paper focusing more on convincing the reader it could do so and quantify the errors with higher resolution results in the experiments presented here. In many of the experiments, either 16km is the highest resolution, or higher resolutions is used without comparing with results at 16km. For this reason, I find this study incomplete, and I strongly encourage the authors to add simulations to their suite of runs. Also, please, be a bit more quantitative in your analysis of each experiment.
Teachers’ language practices and choices in a bilingual, co-located kindergarten in Finland

This article explores the language practices and choices of four teachers in a co-located kindergarten in Finland. Following Finland’s official bilingualism, the education system is built on two tracks – Finnish and Swedish. As official languages of Finland, the two languages share the same status, but since Finnish is the registered language of the vast majority of the population, Swedish can be seen as a de facto minority language – one reason why Swedish education has been seen as an important space for maintaining Swedish language and culture. This constitutes an important perspective for research on Finnish and Swedish early childhood education units that are located in the same building. In this article, the language practices and choices of four kindergarten teachers are examined. The teachers worked in different groups: two of them in Swedish groups and two in Finnish groups. These teachers’ everyday activities were observed and recorded, and the teachers were interviewed about their language practices and choices. Through data source and methodological triangulation, this article illustrates how the teachers worked side by side in collaboration and across language borders, and thus created a feeling of community between the Finnish and Swedish groups. Sharing some of the spaces and activities broadened the space and made it more bilingual. At the same time, the teachers’ language practices gave extra support to Swedish, which was used not only in the Swedish groups but also with bilinguals in the Finnish groups.
Reversal of G-Quadruplexes’ Role in Translation Control When Present in the Context of an IRES

G-quadruplexes (GQs) are secondary nucleic acid structures that play regulatory roles in various cellular processes. G-quadruplex-forming sequences present within the 5′ UTR of mRNAs can function not only as repressors of translation but also as elements required for optimum function. Based upon previous reports, the majority of the 5′ UTR GQ structures inhibit translation, presumably by blocking the ribosome scanning process that is essential for detection of the initiation codon. However, there are certain mRNAs containing GQs that have been identified as positive regulators of translation, as they are needed for translation initiation. While most cellular mRNAs utilize the 5′ cap structure to undergo cap-dependent translation initiation, many rely on cap-independent translation under certain conditions in which the cap-dependent initiation mechanism is not viable or slowed down, for example, during development, under stress and in many diseases. Cap-independent translation mainly occurs via Internal Ribosomal Entry Sites (IRESs) that are located in the 5′ UTR of mRNAs and are equipped with structural features that can recruit the ribosome or other factors to initiate translation without the need for a 5′ cap. In this review, we will focus only on the role of RNA GQs present in the 5′ UTR of mRNAs, where they play a critical role in translation initiation, and discuss the potential mechanism of this phenomenon, which is yet to be fully delineated.
Application of intelligent tools to detect and classify broken rotor bars in three-phase induction motors fed by an inverter

A comprehensive study of intelligent tools used to classify broken rotor bars in induction motors, which operate with three different types of frequency inverters, is presented. The diagnosis of defective rotor bars is a critical issue for the predictive maintenance of induction motors. A proper classification of these defects in their early stages of evolution is necessary for preventing major machine failures and production downtime. The proposed approach is performed by analysing the amplitude of the stator current signal in the time domain, using a dynamic acquisition rate based on machine frequency supply. To assess classification accuracy under the various severity levels of the faults, the performance of four different learning machine techniques is investigated: (i) fuzzy ARTMAP network; (ii) support vector machine (sequential minimal optimisation); (iii) k-nearest neighbour; and (iv) multilayer perceptron network. Results obtained from 1274 experimental tests are presented in order to validate the study, which considers a wide range of load conditions and operating frequencies. Experimental results presented in this study validate the robustness and efficacy of the proposed approach.
Estimating Embodied Energy in Residential Buildings in a Nigerian Context

The housing sector in Nigeria is characterized by huge deficits coupled with un-innovative construction methods. Previous studies indicate a strong relationship between construction materials and techniques on the one hand and embodied energy on the other. Also, studies on construction innovation in Nigeria have focused on its economic and financial benefits while playing down the environmental implications. This paper examined the environmental implications of residential building construction in a Nigerian context using embodied energy as an index of measurement with a view to identifying areas that could benefit from innovative strategies. Primary data for the study were obtained from survey research complemented by observation and interviews. For the embodied energy estimation, the life cycle assessment (LCA) framework and international energy protocols were adopted for the study. The study found that opportunities for embodied energy mitigation exist mostly in the building frame and walls as well as in the recurring embodied energy component. In other to achieve substantial reduction in the embodied energy intensity, substitution of conventional building materials with low energy and durable materials as well as adoption of innovative construction methods were recommended.

The impact of “freedom day” on COVID-19 health protective behaviour in England: An observational study of hand hygiene, face covering use and physical distancing in public spaces pre and post the relaxing of restrictions

Objectives: To study the prevalence of COVID-19 health protective behaviours before and after rules eased in England on the 19th July 2021. Design: Observational study pre (12th-18th July) and post (26th July-1st August) 19th July, and a cross-sectional online survey (26th to 27th July). Setting: Observations occurred in supermarkets (n = 10), train stations (n = 10), bus stops (n = 10), a coach station (n = 1) and a London Underground station (n = 1). The survey recruited a nationally representative sample. Participants: All adults entering the observed locations during a one-hour period (n = 3819 pre- and n = 2948 post-19th July). In the online survey, 1472 respondents reported having been shopping for groceries/visited a pharmacy and 566 reported having used public transport or having been in a taxi/minicab in the last week. Main outcome measures: We observed whether people wore a face covering, maintained distance from others and cleaned their hands. We investigated self-reports of wearing a face covering while in shops or using public transport. Results: In most locations observed, the proportion of people wearing face coverings, cleaning the hands and maintaining physical distance declined post 19th July. Pre 19th July, 70.2% (95% CI 68.7 to 71.7%) of people were observed to be wearing a face covering versus 55.8% (54.2 to 57.9%) post 19th July. Equivalent rates for physical distancing were 40.9% (39.0 to 42.8%) versus 29.5% (27.4 to 31.7%), and for hand hygiene were 4.4% (3.8 to 5.1%) versus 3.9% (3.2 to 4.6%). Self-reports of “always” wearing face coverings were broadly similar to observed rates. Conclusions: Adherence to protective behaviours was sub-optimal and declined during the relaxation of restrictions, despite appeals to exercise caution. Self-reports of “always” wearing a face covering in specific locations appear valid.
Predator-Prey Interactions between Nonnative Juvenile Largemouth Bass (Micropterus salmoides) and Local Candidate Prey Species in the Pearl River Delta: Predation Capacity, Preference and Growth Performance

An ontogenetic dietary shift is crucial for the survival and growth of piscivorous largemouth bass (LB). However, there is much to learn about the predator-prey interaction during the switching process. We carried out a series of indoor experiments to examine the predation capacity, predation preference, and growth performance of exotic juvenile LB feeding on candidate prey species in the Pearl River Delta. The widely distributed oriental river prawn (Macrobranchium nipponense), barcheek goby (Ctenogobius giurinus), western mosquitofish (Gambusia affinis), silver carp (Hypophthalmichthys molitrix), and mud carp (Cirrhinus molitorella), with relatively similar total lengths, were selected as potential prey based on their availability and habitat use. Our results show that predation capacity and preference varied quantitatively and qualitatively among prey species. The number of oriental river prawns killed was significantly less than that of fish species, comparing the 1st hour with the 24th hour (p < 0.01). The feeding rhythm of LB varied significantly from crayfish to fish. Numerically, Jacobs’ selection index reinforced LB’s special preference for predating G. affinis. Although there were obvious variations in predation capacity and feed selection, no statistically significant growth differences were detected among LB groups feeding on live M. nipponense, G. affinis, H. molitrix, and C. molitorella (p < 0.05). These findings suggest that the successful ontogenetic dietary shift of juvenile LB may depend on the availability and vulnerability of local fish species. Further study on the reproductive phenology of potential fish prey may help to predict LB’s establishment.
