The outbreak of Covid-19 has changed education, including the mechanism of delivery of gross pathology laboratories. Herein, we describe how we revised our preclinical gross pathology lab to a flipped model to fit with COVID-19 regulations. A series of short, session objective-driven videos are made available online. Students are expected to watch the videos before coming to the hands-on lab. Groups of 2 students enter the gross lab on a timed basis and rotate through a series of stations. At each station, students examine gross pathology specimens while answering questions designed to apply the clinical correlation of pathophysiology and heighten observational skills. One or 2 pathologists are available throughout the lab session to address the questions from the students. The design of this laboratory exercise maintains appropriate distancing and hygiene in the time of COVID-19. The laboratory rooms are mapped to set up an appropriate number of timed stations. Flow-through of the rooms is unidirectional. Comparing with the traditional show-and-tell of teaching gross pathology, the renovated flipped model is genuinely student-centered and focuses on active learning. Holding the specimen in their hands, students learn from discovery as they are completely engaged by exploring the specimen and deriving answers themselves. The flipped learning gross pathology method has been very well received and evaluated highly by both faculty and students.

Faculty Workshop

A great deal of interest has emerged recently in the flipped classroom (FC), a student-centered teaching approach. After attending a presentation by the first author on the FC, a faculty member of a medical school in Mexico arranged for a 3-day workshop for 13 faculty members. The goal of the workshop was to train faculty to use the FC strategy in their classrooms to increase student engagement in learning. The workshop was in the FC style, where the participants would assume the role of students. Pre- and posttraining surveys were administered to examine participants’ current teaching practices and to evaluate their perceptions of the FC. The participants overwhelmingly reported the need to change their lecture-based teaching, as it was not engaging students. Their large class size, lack of technology, training, and uncertainty of the effectiveness of new teaching methods had hindered participants from changing their teaching technique. The on-site training not only allowed the entire department to work closely and discuss the new teaching approach, but also reinforced the idea of changing their teaching strategy and embracing FC teaching method. After the workshop, participants reported being determined to use the FC strategy in their classrooms and felt more prepared to do so. The post-survey results indicated that participants valued the FC training in the flipped style and wanted more of the hands-on activities. In conclusion, the 3-day faculty workshop on the FC was successful, since every participant was motivated to use this teaching method.

We developed a laboratory exercise that involves the construction and subsequent manipulation of a model of the cardiovascular system. The laboratory was designed to engage students in interactive, inquiry-based learning and to stimulate interest for future science study. The model presents a concrete means by which cardiovascular mechanics can be understood as well as a focal point for student interaction and discussion of cardiovascular principles. The laboratory contains directions for the construction of an inexpensive, easy-to-build model as well as an experimental protocol. From this experience students may gain an appreciation fo science that cannot be obtained by reading a book or interacting with a computer. Students not only learn the significant physiological concepts but also appreciate the importance of laboratory experimentation for understanding complex concepts. Model construction provides a hands-on experience that may substantially improve performance in science processes. We believe that model construction is an appropriate method for teaching advanced concepts.

Teaching wireless networking fundamentals is often difficult because many students appear to find the subject technical, and dry when presented in traditional lecture format. To overcome this problem, we provide an opportunity for experiential learning where students can learn wireless networking fundamentals by hands-on practical activities using low-cost Wi-Fi (wireless fidelity) devices such as wireless cards and access points. Students can easily set up and configure networks using wireless cards and access points more effectively. By measuring network performance such as throughput and end-to-end delays, students are able to gain a deeper understanding of wireless networking. The effectiveness of Wi-Fi-based practical activities has been evaluated by students and the teaching team. This chapter reports on the overall effectiveness of teaching and learning of wireless network using radially available low-cost Wi-Fi cards and access points.

Set Up

A technique is presented to measure platelet aggregation (PA) and platelet shape change (PSC) with high accuracy in small samples (100 ul) using a turbidimetric method wich a He-Ne-Laser as light source. Both, transmitted and scattered light, Is measured by two independent light sensitive elements. Transmitted light is detected by a photodiode with a sensitive area of 1 mm2 covering a space angle of Ω= 0.004 sterad. Scattered light is detected by a photoelement surrounding the photodiode which covers a space angle of U-1.4 sterad. Ar, electronic set up forms a signal, which is proportional to the ratio scattered light/scattered light + transmitted light.The output voltage is linearly correlated to the turbidity of the suspension. The whole set up is employed with three different types of cuvettes.1. A cuvette where through a semipermeable hollow fiber membrane different drugs can diffuse into the platelet suspensions avoiding any stirring of the sample ()2. A flow through cuvette to measure the extent of PA in PRP samples.3. A couette type platelet aggregometer.

Set Up

A free-zone electrophoresis system is used for rapid production of substantially purified factor VIII from either citrated plasma or from a factor VIII Concentrate of intermediate purety. Using concentrate, a total yield of 43% of clotting activity is obtained with fibrinogen reduced to approximately 30% of its starting level. Protein level is reduced to 20% of the original value. Using plasma, the albumin, factor VIII and fibrinogen were all separated from factor VIII. In these experiments, factor-VIII-related antigen migrates with the coagulant factor VIII illustrating that both have similar mobilities equivalent to that of an alpha-globulin, or else that they are connected together. The particular advantage of this separation is that it is carried out in a continuous flow apparatus in liquid buffer with no solid matrix and that once the apparatus is set up, material can flow through the machine at a rate of 5 mls/min being continuously separated. The main problem and area for further study is that of concentrating the relatively dilute fractions without undue loss.

Microplastic pollution is an environmental threat with substantial effects on ecosystems. Persistence and ubiquity are the central causes of the problems microplastics generate, especially throughout water-based food webs. To limit microplastic pollution, accountability of individuals is needed, which requires reliable information for an individual to act accordingly. Knowledge about sources, contamination, fate, and effects of microplastic in the environment may be an essential element in enhancing students' motivation and sense of responsibility. Our module “Plastic Detectives – The Search for Plastic” offers consciousness-raising tasks that involve students in hands-on learning activities. Within student-centered activities, different tasks on sources in everyday life, sinks in aquatic ecosystems, effects on marine animals, and prevention strategies for microplastics are in focus. With an appropriate overview, students may be sufficiently enabled to ponder their purchase decisions and potentially limit microplastic pollution in everyday life.

Government Level

Purpose – The purpose of this paper is to examine how the structure of government-funded event agencies affected the development of the events industry in Northern Ireland. The institutional arrangements for two agencies which operated at different times in Northern Ireland were analysed. Design/methodology/approach – A total of 62 in-depth interviews were conducted with event organisers and public officials who had worked directly with these two organisations. Findings – The standalone National Events Agency which began operating in 1999 was found to be more hands-on and worked closely with event organisers to develop the quality of their event. As a quango it worked at arms length from government. Unfortunately it abused this freedom and used public monies to manage its own events, highlighting the need for transparency and accountability when managing this type of agency. In 2008 it was replaced by an Events Unit which was set up within the National Tourism Organisation. Under this structure event tourism and not event development was the priority. For the events industry this created development issues and reduced its clout at government level. Originality/value – This paper addressed a gap in the literature and found that the institutional arrangements did affect how a government-funded events agency operated and what it regarded as a strategic priority. This in turn had repercussions for the development of the events industry.

Sick Pay

During the 1930s there were allegations that London bus drivers and conductors had an undue amount of sickness, especially gastric disorders. Dr Bradford Hill (1937) was asked to investigate this allegation, but found that the data were limited. The London Passenger Transport Board determined that in the future adequate data for such investigations should be available. This was not possible until after the war. In 1948 the Central Record of Staff Statistics was set up to compile sickness-absence statistics and for other purposes. This lecture is mainly an account of the uses made of the statistics produced: how they can be used to study the effect of sick pay provisions, the secular trend of sickness absence in occupational groups, and the differences in sickness-absence experience between groups of various kinds. If the experience of these groups is related to the employees' work and the conditions under which it is done, the results are valuable in answering questions on health from management and unions. The data collected can also be used in medical administration and for research into the causation of disease.

Purpose – The purpose of this paper is to describe how librarians at the State University of New York College at Buffalo used iPads during one class session of a semester-long library instruction course to increase student engagement, energize the traditional library tour, build collaboration and give students experience using tablet technology in an educational setting. Design/methodology/approach – Librarians provided iPads to groups of students and sent them to photograph different areas of the library during one class session of a semester-long course. Students then uploaded the photographs to a common Web site for class discussion. Findings – Formal and informal student feedback was positive. Students connected with the instructors and with each other, enjoyed discovering library spaces and services and became more comfortable with tablet technology. The project also increased student enthusiasm for the class. Originality/value – This paper is the first to systematically describe a simple activity that can be used by instruction librarians to incorporate tablets into the curriculum. The method requires minimal time to set up and implement, involves a very short learning curve and is easily adaptable to various mobile devices.
