This article, the purpose of which is to deal with some problems in studying and teaching English, is merely for the students of English to read, who have just entered the second year at a foreign languages institute. When teaching the second-year students, I have often been asked this awkward question: "What do you think is the correct way to study English?" It took me quite a time to answer it. Now after many years of teaching I think I have some ideas on this subject. 展开更多

This paper reports the results acquired in a research work about "questionable" practices and behaviors in the academic production of researches and postgraduate social sciences and humanities studies of the programs that are appointed by the National Program of Quality Postgraduate Studies (PNPC, by its acronym in Spanish) in Mexico. Through a qualitative methodology, the authors interpreted some of the arguments that explain and/or justify certain practices in relation to doubled production, authorship, and coauthorship of academic products. In this paper, the authors present and analyze the results that they obtained after reviewing documents produced by professors and students of six postgraduate programs that are taught in two Mexican public universities. At the same time, the authors examine some of the practices that take place within said programs, given the institutional demands of improving finished studies efficiency. One of the hypotheses of this work is the demands that are imposed by external evaluations of academic processes on professors and their programs in order to reach desirable rates with the purpose of maintaining or increasing the levels of productivity, gives way to certain practices that must be analyzed. This work's theoretic framework is constituted by the contributions of career sociology and professional ethics. 展开更多

This paper compares 12 representative Chinese and English online questionanswering communities(Q&A communities) based on their basic functions, interactive modes, and customized services. An empirical experiment from a comparative perspective was also conducted on them by using 12 questions representing for four types of questions,which are assigned evenly to three different subject fields so as to examine the task performance of these 12 selected online Q&A communities. Our goal was to evaluate those online Q&A communities in terms of their quality and efficiency for answering questions posed to them. It was hoped that our empirical research would yield greater understanding and insights to the working intricacy of these online Q&A communities and hence their possible further improvement. 展开更多

Two motor-cognitive interventions were implemented to evaluate their efficacy in cognitive improvement in Mexican older adults 65 years and more. The intervention group received a dance video games plus a cognitive task (dual-task);the comparison group received only the dance video game, in sessions of 45 minutes, 3 times a week, for 12 weeks. The Barthel Index and Lawton and Brody Index, the Center for Epidemiologic Studies Depression Scale-Revised were applied the Digit Span Test, the Stroop Test, and Color Trail Making. Gait parameters were assessed by GAITRite? electronic walkway (CIR Systems). The design was quasi-experimental. Sites were randomly assigned to intervention groups. The intervention group started with 32 participants and finished with 15;the comparison group started with 20 participants and finished with 18. Participants in the intervention group had to mimic the dance movement of a video game and, after the second week to name progressively three objects without stopping dancing. A multivariate repeated measures model (MANO-VA) was fit with four variables. A time-by-group interaction was observed in the Stroop test, and Digits Span Backwards was in favor of the dual task group. The Stroop test, Digit Span Backwards, gait speed, and step length showed effect time. Both groups improved in gait speed and step length by the end of the intervention. Results show it is feasible for Mexican older adults with little schooling to perform dual tasks and improve cognitive tasks and gait speed. Limitations were high attrition due to unforeseen situations and small sample size. 展开更多

Objective:This study aimed to explore the existing knowledge about midwives’views and experiences of providing care for women in the context of task shifting.Methods:We conducted a qualitative systematic review using meta-ethnography to describe the views and experiences of midwives on providing care in the context of task shifting.Comparative textual analysis of published qualitative studies involved translation of first-order key concepts and meanings from included studies to generate second-and third-order concepts.A grid was made to identify core findings and compare them reciprocally.Results:Thirty-six qualitative studies met the inclusion criteria.The literature comprised of 32 first key concepts.Eight second-order constructs emerged,and three third-order interpretations were generated.The three overarching themes were:(1)midwives perceived themselves as providing culturally competent and high quality women-centered care;(2)they valued their profession but saw it as complex and challenging;(3)as health professionals,they reported a variety of organizational,cultural,and professional barriers to providing women-centered care.Conclusions:While performing a specific task in the task shifting context,midwives perceived their crucial roles and responsibilities,along with achieved value and reward.However,due to a range of existing barriers,the caring task posed great challenges in completely implementing women-centered care.It is essential for systems to identify and eliminate these barriers early,to consider midwives’emotional well-being,and to develop overall strategies to better support the midwifery workforce.Policy makers and administrators should establish a supportive environment to facilitate midwives to perform women-centered caring tasks in more effective and efficient ways. 展开更多

Incidental visualizations convey information to a person during an ongoing primary task,without the person consciously searching for or requesting that information.They differ from glanceable visualizations by not being people’s main focus,and from ambient visualizations by not being embedded in the environment.Instead,they are presented as secondary information that can be observed without a person losing focus on their current task.However,despite extensive research on glanceable and ambient visualizations,the topic of incidental visualizations is yet a novel topic in current research.To bridge this gap,we conducted an empirical user study presenting participants with an incidental visualization while performing a primary task.We aimed to understand how complexity contributory factors—task complexity,output complexity,and pressure—affected primary task performance and incidental visualization accuracy.Our findings showed that incidental visualizations effectively conveyed information without disrupting the primary task,but working memory limitations should be considered.Additionally,output and pressure significantly influenced the primary task’s results.In conclusion,our study provides insights into the perception accuracy and performance impact of incidental visualizations in relation to complexity factors. 展开更多
