Flipped Classrooms

While current research on the flipped classroom generally focuses on test results and (or) student/teacher perceptions as a measurement of its pedagogical efficacy, students' adaptation to it and the essential conditions for its application are rarely explored. This exploratory case study aims to rectify this by examining how university students adapted to flipped classrooms implemented in a public university in East China. The findings suggest that while the flipped model is impeded by entrenched polarity between students in terms of their learning dispositions and academic competence, students do develop a prototype of theories of learning, a sense of better self through learning from their peers and an awareness of the importance of intrinsic motivation. A gradualist approach is thus proposed for implementing flipped classrooms, which requires longitudinal studies accordingly to understand its long-term effects on learning behavior hitherto left unexplored.

Using the 2008 Zaragoza International Exhibition “Water and sustainable development” as a case study, this paper aims to respond to the increasing demand for measurements of the effects and the implications of the performance of cross-sector partnerships from the perspective of their intended final beneficiaries. A contingency framework for measuring the short-, medium- and long-term effects of the 2008 Zaragoza International Exhibition is developed based on a “results chain” or “logic model”. Our results highlight that there are positive long-term synergies between the two main purposes of the 2008 Zaragoza International Exhibition; first, to increase public awareness of and commitment to the problems of water and sustainable development and, second, to make the city of Zaragoza better known internationally and to modernize its infrastructures. Although respondents to our survey consider that the long-term effects on the city are greater, the main short- and medium-term effects are related to awareness of water problems, sustainable development and non-governmental organizations. These results are in tune with what has happened around the city in the last 10 years providing indirect validity both to our study and to the proposed methodology.

It is known that bolt forces reduce significantly after tightening bolted flanged connections in which expanded PTFE gaskets are used. Bolts are often post-tightened in practice after a while to compensate for the reduction of bolt forces. The viscoelastic characteristic of expanded PTFE gaskets is the main cause for the phenomenon. However, the long term effects of the post-tightening on the residual bolt forces and the sealing performance of flanged connections have not been clarified yet. In this study, two sets of flanged connections (2 inch in nominal size), in which PTFE gaskets were used, were prepared and tightened. One of the flanges was post-tightened after a designated time. The reduction of bolt forces and the change in the sealing performance were measured for about two months. The results were compared with those of flanges without post-tightening. Based on the test results, the effectiveness of post-tightening was discussed from the viewpoint of the residual bolt force and the sealing performance. It has been clarified that the effectiveness of post-tightening depends on gasket material and that post-tightening is effective for expanded PTFE gaskets.

Customer Centricity

Purpose – The purpose of this paper is to argue that in order to achieve customer centricity through business process management (BPM), companies have to obtain the profound understanding of customers’ processes and when necessary change not only the interactions with but also the processes of their customers. A method is presented that allows doing this in a systematic manner. Design/methodology/approach – A case study of a large multinational company was conducted. Several different sources and methods were used, including document analysis, interviews and a qualitative analysis of responses to open-ended questions. Data were gathered at three points in time: before, during and after the implementation of the presented approach. Findings – The method that was successfully employed by the case organisation consisted of combining BPM with service blueprinting, and of extending these efforts by integrating the customers’ internal processes into the scope of improvement. Research limitations/implications – The paper does not thoroughly evaluate the long-term effects of the proposed approach. Some results of the case study analysis had to be excluded from this paper due to reasons of confidentiality. Practical implications – The paper presents an approach for organisations to not only understand the needs of their customers but also the way in which their product is used in customers’ processes. In this way BPM can be implemented in a truly customer-oriented way. Originality/value – This paper extends previous work by presenting one way in which BPM can follow up on its promise of increasing an organisations customer orientation. While servitisation has received a lot of attention in various disciplines, its application within BPM research and practice has been scarce.

Answer Copying

In educational testing, answer-copying is considered a behaviour that poses threats to the validity of test scores interpretations, which is a concern when interpreting the test results for the purpose of making changes to curriculum and educational policies. Answer copying involves at least two examinees, one being the source and the other the copier. While different methods have been developed to detect answer-copying using statistical indices, researchers have not yet examined the use of video digitizing technology via a kinematic sanalysis of the data to detect answer-copying during test taking situations. The purpose of this case study was to explore the use of video digitizing technology to detectanswer-copying by measuring examinees’ response time, displacement and velocity from item to item on a test. A sample of two university students volunteered to demonstrate the benefits and challenges of using video digitizing technology to detect answer-copying. While this is a small scale demonstration, the outcome of this study may shed light on whether or not the use of video digitizing technology provide evidence of feasibility and some preliminary reliability in the detection of answer copying.The lesson learned from this study can inform the direction of a future program of research.

AbstractBackgroundCohort studies of people with a history of COVID-19 infection and controls will be essential to understand the epidemiology of long-term effects. However, clinical diagnosis requires resources that are frequently restricted to the severely ill. Cohort studies may have to rely on surrogate indicators of COVID-19 illness. We describe the prevalence and overlap of five potential indicators: self-reported suspicion, self-reported core symptoms, symptom algorithm, self-reported routine test results, and home antibody testing.MethodsAn occupational cohort of staff and postgraduate students at a large London university who participated in surveys and antibody testing. Self-report items cover March to June 2020 and antibody test results from ‘lateral flow’ IgG/IgM antibody test cassettes sent to participants in June 2020.ResultsValid antibody test results were returned for 1882 participants. Of the COVID-19 indicators, the highest prevalence was core symptoms (770 participants positive, 41%), followed by participant suspicion of infection (n=509, 27%), a symptom algorithm (n=297, 16%), study antibody positive test (n=124, 6.6%) and self-report of a positive external test (n=39, 2.1%). Study antibody positive result was rare in people who had no suspicion they had experienced COVID-19 (n=4, 0.7%) or did not experience core symptoms (n=10, 1.6%). When study antibody test results were compared with earlier external antibody results in those who had reported them, the study antibody results agreed in 88% cases (kappa= 0.636), with a lower proportion testing positive on this occasion (proportion with antibodies detected 15% in study test vs 24% in external testing).DiscussionOur results demonstrate that there is some agreement between different COVID indicators, but that they a more complete story when used together. Antibody testing may provide greater certainty and be one of the only ways to detect asymptomatic cases, but is likely to under-ascertain due to weak antibody responses to mild infection, which wane over time. Cohort studies will need to review how they deal with different and sometimes conflicting indicators of COVID-19 illness in order to study the long-term outcomes of COVID-19 infection and related impacts.What is already known on this subject?Research into the effects of COVID-19 in the community is needed to respond to the pandemic. Objective testing has not been widely available and accuracy may not be high when carried out in retrospect. Many cohort studies are considering how best to measure COVID-19 infection status.What this study adds?Antibody testing is feasible, but it is possible that sensitivity may be poor. Each indicator included added different aspects to the ascertainment of COVID-19 exposure. Using combinations of self-reported and objectively measured variables, it may be possible to tailor COVID-19 indicators to the situation.

Purpose The purpose of this case study is to investigate how the personnel in an organization experienced the process of change when moving from private offices to an activity-based office (ABO) and how their perceptions of change were associated with changes in their satisfaction with the work environment a year after relocation. Design/methodology/approach A comparative pre-post study design and mixed methods were used. Survey data was obtained from 154 employees before the relocation and 146 after the relocation. The data on the 105 employees who responded to both surveys were statistically analyzed. Representatives of different units were interviewed (n = 17) and documentary material was analyzed as complementary material. Findings The personnel’s criticisms concerned the reasons for the change, their opportunities to influence the office design and the extent to which their views were taken into account. Environmental satisfaction decreased after moving to the ABO. The personnel’s ratings of the workplace change process before the relocation were associated with the later change in environmental satisfaction. Based on logistic regression, the degree of agreement with management’s reasons for the change was the strongest predictor of the change in environmental satisfaction. Practical implications Organizations that move from private offices to an ABO should invest in high-quality change management and simultaneously develop both work and facilities. Special attention should be paid to clarifying the rationale for the change to the employees and to providing them with opportunities to influence during the change. Organizations should continue to monitor user experiences and evaluate the effects of the change after the office redesign and should take corrective action as needed. Originality/value This empirical case study is unique as it combined qualitative and quantitative methods and investigated the process of relocation and its outcomes in a one-year follow-up. This approach captured the importance of managing change and assessing the long-term effects of office redesign when moving from private offices to an ABO.

Abstract Objective Soroxchi/Acute Mountain Sickness (AMS) is a condition that can result in cerebral and pulmonary hypoxia. Neuropsychological research on AMS is minimal and the long-term effects on cognition and behavior are unclear. AMS is associated with cognitive impairments in processing speed, attention, and executive functions as well as neurobehavioral symptoms. This case study delineates the neuropsychological and neurobehavioral changes secondary to bilateral globus pallidus (GP) lesions associated with AMS. Case Description Patient is a 51-year old, primarily Spanish-speaking, male of Mexican descent with 9 years of education, and who had traveled to La Paz, Bolivia (4,070 MASL) for work. Upon arrival, fatigue and dizziness led to hospitalization to treat acute pulmonary edema and hypoxia. Brain MRI revealed hyperintense bilateral GP lesions. Medical history was notable for hyperlipidemia. Psychiatric history was unremarkable. Neuropsychological assessment 4 months post-AMS revealed impairments in visuo-conceptual and speeded complex visuospatial abilities, executive functions, and confrontation naming. Cognitive improvements were noted in delayed recall of non-contextual verbal information and confrontation naming ten months post-AMS. Significant mood and personality changes were reported; patient endorsed anhedonia, fatigue, alexithymia, avolition, and sleep difficulties. Family described patient as depressed, apathetic, and socially withdrawn. Pharmacological and psychotherapy treatments were recommended and initiated. Diagnostic Impressions and Outcomes Findings were consistent with a diagnosis of Mild Neurocognitive Disorder. His family denied neurobehavioral improvements post interventions. Discussion This case study is the first to characterize the long-term neuropsychological and neurobehavioral changes following bilateral GP lesions secondary to AMS. Declines in visual-conceptual abilities reveal a new finding for this type of cerebral incident.
