IntroductionFollowing a pandemic, laboratory medicine is vulnerable to laboratory errors due to the stressful and high workloads. We aimed to examine how laboratory errors may arise from factors, e.g., flexible working order, staff displacement, changes in the number of tests, and samples will reflect on the total test process (TTP) during the pandemic period.Materials and methodsIn 12 months, 6 months before and during the pandemic, laboratory errors were assessed via quality indicators (QIs) related to TTP phases. QIs were grouped as pre-, intra- and postanalytical. The results of QIs were expressed in defect percentages and sigma, evaluated with 3 levels of performance quality: 25th, 50th and 75th percentile values.ResultsWhen the pre- and during pandemic periods were compared, the sigma value of the samples not received was significantly lower in pre-pandemic group than during pandemic group (4.7σ vs. 5.4σ, P = 0.003). The sigma values of samples transported inappropriately and haemolysed samples were significantly higher in pre-pandemic period than during pandemic (5.0σ vs. 4.9σ, 4.3σ vs. 4.1σ; P = 0.046 and P = 0.044, respectively). Sigma value of tests with inappropriate IQC performances was lower during pandemic compared to the pre-pandemic period (3.3σ vs. 3.2σ, P = 0.081). Sigma value of the reports delivered outside the specified time was higher during pandemic than pre-pandemic period (3.0σ vs. 3.1σ, P = 0.030).ConclusionIn all TTP phases, some quality indicators improved while others regressed during the pandemic period. It was observed that preanalytical phase was affected more by the pandemic. 相似文献

Learning takes place in various spaces through human and nonhuman interactions. Considering the urgent need for rethinking how humans relate to nature, in this article we present a MA level course in the context of art, craft and design to discuss how learning with the natural environment approach can impact learning experiences. We introduce walking with nature as a creative method that fosters students’ ability to let the environment actively shape their creative events. The encounter with nature-based materials in their different forms and following the material's flow provides students with a foundation for their creative processes. This study proposes that walking can facilitate the entanglement between the student's knowledge and encountered materials, generating an emotional and dialogical relationship with the natural environment that contributes to a holistic learning experience. We propose that such an experience can help in comprehending the importance of the caring actions we need to take and maintain towards the nonhuman world. 相似文献

ABSTRACTThis paper explores the perspectives of Flemish secondary school principals and coordinating principals on the government-proposed changes and uncovers their experiences with these changes in an in-depth manner. In a school system characterised by school freedom and free school choice, semi-structured interviews with 21 school leaders revealed the significance of school autonomy to create bottom-up solutions to the change-related problems. However, infrastructure, monetary resources, teacher, and parent reactions sometimes proved to be obstacles, jeopardised effective implementation, and affected the leaders’ workload extensively. The results showed the critical roles played by the school principals to satisfy the change-related needs of the staff and motivate them for change. The findings collectively suggest the need for more attention devoted to 1) the human side of the change, 2) greater support provided throughout the process, and 3) a loose connection between politics and change-related decisions. 相似文献

The purpose of this study was to investigate and compare the impact of task-based instruction (TBI) and traditional instruction (TI) on the motivation and vocabulary development in secondary language education. The focus of the study was to also find out the perceptions of teachers about implementing these two instructional methods in their teaching practices. The participants were 97 students and 2 teachers engaged in the 7th grade EFL program at a private school in Istanbul, Turkey. Data was collected quantitatively from a vocabulary check test and motivation scale, as well as qualitatively from semi-structured interviews. The findings revealed that implementing TBI had positive impact on students' vocabulary development as well as their motivation. In line with these findings, it was also suggested that teachers perceived TBI to be a more effective method to be incorporated in secondary grade language practices. Based on the gathered findings, suggestions for redesigning and implementing the existing 7th grade EFL program were provided. 相似文献

This study aims at building a theoretical base for continuous change in education and using this base to test the mediating roles of two key contextual variables, knowledge sharing and trust, in the relationship between the distributed leadership perceptions and continuous change behaviours of teachers. Data were collected from 687 public school teachers. The results showed that the combined effect of knowledge sharing and faculty trust in principal mediated the relationship between teachers’ distributed leadership perceptions and continuous change behaviours. The directions of the coefficients of the relationships between the independent variable and the dependent variable suggested that higher distributed leadership perception leads to increased knowledge sharing and trust in principal, which in turn was associated with greater continuous change behaviours. The study showed that school systems have an extensive capacity for self-improvement, even in the absence of a pre-developed change plan. 相似文献

Attacks on academic freedom in Turkey have become increasingly systematic in recent years and thousands of academics have been dismissed. This study reflects on the effects of this worsening repression through interviews with academics in the social sciences, both those dismissed and those still active in their profession. Although the dismissed academics are socially in a very precarious position, they are continuing their scholarly activities in alternative, underground forms. This resistance stands in contrast to the accommodation and self-censorship that seem, according to the interviewees, to prevail in university departments. 相似文献

Abstract： An innovative occupant friendly retrofitting technique has been developed for reinforced concrete （RC） building structures with hollow brick infill wails used as partition walls which constitute the major portion of the existing building stock in Turkey. The idea is to convert the existing hollow brick infill wall into a load carrying system acting as a cast-in-place RC wall by reinforcing it with relatively thin concrete plates bonded to the mortar coated infill wall by use of tile adhesive and fixed by qb6 （6 mm diameter） bolts. Test parameters were the shape and thickness of the plates, presence of reinforcement in plates, number and arrangement of O6 bolts. It was observed that lateral strength, stiffness, energy dissipation capacity, and ductility of the strengthened infill walls were improved and behaviour was enhanced by the proposed technique. Plates with two different basic shapes were used to strengthen the test specimens. 相似文献

The aim of this study was to evaluate the possible therapeutic or protective effects of Helichrysum plicatum DC. subsp. plicatum ethanol extract (HPE) against gentamicin-induced nephrotoxicity. Thirty-six Sprague Dawley male rats weighing between 200 and 250 g were used as live material. They were formed into six groups containing 6 rats each and were allowed to adapt to laboratory conditions for 7 d. Group I: control, 5% DMSO intraperitoneal (i.p.); Group II: HPE 100 mg/(kg·d) i.p.; Group III: HPE 200 mg/(kg·d) i.p.; Group IV: gentamicin as 80 mg/(kg·d) i.p.; Group V: gentamicin as 80 mg/(kg·d) i.p.+HPE 100 mg/(kg·d) i.p.; and Group VI: gentamicin as 80 mg/(kg·d) i.p.+HPE 200 mg/(kg·d) i.p. for 8 d. Following treatment, serum, liver, and kidney tissues were used to assess blood urea nitrogen (BUN), creatinine, enzymatic and non-enzymatic antioxidants, and lipid peroxidation. Gentamicin significantly increased serum BUN, creatinin, and liver and kidney levels of malondialdehyde (MDA). It also decreased the activity of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD). Treatment with the HPE 100 mg/kg reversed gentamicin-induced alterations as evidenced by decreased serum BUN and creatinin, liver and kidney oxidant marker, and tubular necrosis as well as by an increase in antioxidant enzymes. It was found that HPE 200 mg/kg significantly increased liver and kidney tissue MDA levels in nephrotoxicity in rats. As a result, these findings support the proposition that HPE in 100 mg/kg dose demonstrates in the kidney and liver as free radicals and scavenger to prevent the toxic effects of gentamicin in both the biochemical and histopathology parameters. 相似文献

Higher education systems need to increasingly transform in order to face new challenges of society in a modern and global context. Both Europe and China are facing challenges in restructuring their higher education systems and embracing the potential for higher education to deliver innovative teaching and learning as well as social and economic services for a changing society. This paper analyses the challenges to European and Chinese universities today and elaborates on the implications of these challenges for EU-China higher education collaboration. An analysis of challenges and relevant strategies in these two contexts can offer us insights into the strengths and weaknesses of each system. This can act as a solid basis for future collaborations or as potential barriers. Thus, this paper endeavors to fill in the gap regarding EU-China higher education cooperation by reducing the knowledge deficit and bringing mutual understanding, respect, trust, and ultimately benefit to both sides. 相似文献
