Flexible working: a new way forward to an old concept

This article provides a high level overview around flexible working, an employer and employees legislative requirements and the benefits available to those who choose to embrace flexible working. Flexible working is not a new concept however COVID-19 has had an impact on working patterns that many companies never considered or wanted to implement. The application of flexible working in the veterinary industry is not well explored, which is concerning given the health and wellbeing concerns the industry already faced prior to the pandemic. Veterinary practices being able to accommodate a flexible working request will always come down to a number of considerations such as position, type of work and the flexible working request that the employee is exploring.

P-OGC13 Chest drainage after oesophageal resection: A systematic review

Background Modern enhanced recovery protocols discourage drain use due to negative impacts on patient comfort, mobility, and recovery, and lack of proven clinical benefit. After oesophagectomy, however, drains are still routinely placed. This review aimed to assess the evidence for, and how best to use chest drains after oesophageal surgery. Methods A systematic literature search was performed in Medline, Embase and Cochrane collaboration databases. Studies reporting outcomes for different types or uses of thoracic drainage, or outcomes related to drains after trans-thoracic oesophagectomy were included. Studies were collated into domains based on variations in number, position, type, removal criteria, diagnostic use and complications of drains. Methodological quality was assessed with Newcastle-Ottawa and Jadad scores. Results Among 434 potentially relevant studies, 27 studies met the inclusion criteria and these included 2564 patients. Studies that examined the number of drains showed pain reduction with a single drain compared to multiple drains (3 studies, n = 103), and transhiatal placement compared to intercostal (6 studies, n = 425). Amylase levels may aid diagnosis of anastomotic leak (9 studies, n = 888). Narrow calibre Blake drains may effectively drain both air and fluid (2 studies, n = 163). Drain removal criteria by daily drainage volumes of up to 300ml did not impact subsequent effusion rates (2 studies, n = 130). Complications related directly to drains were reported by 3 studies (n = 59). Conclusions Available evidence on the impact of thoracic drainage after oesophagectomy is limited, but has the potential to negatively affect outcomes. Further research is required to determine optimum drainage strategies.

Shot Characteristics Based on Match Period in Elite Table Tennis Matches

This study aimed to compare the shot characteristics amongst different match periods in table tennis matches. For the shot characteristics of position, type, placement and efficacy, 13 men’s singles matches comprising 72 sets from a round of 16 to the final in the 2019 World Table Tennis Championships were selected for notational analysis. Kruskal–Wallis and Mann–Whitney tests were conducted to quantify the differences in various categories of each variable amongst the initial, intermediate and ending match periods. There are no significant differences in each distribution between initial and intermediate periods. From intermediate to ending periods, significant decreases were found in chop type (p < 0.01) and middle long placement (p < 0.01), whereas a significant increase was found in backhand half placement (p < 0.05). By comparing the initial and ending periods, significant decreases were found in middle backhand turn position (p < 0.05), middle long placement (p < 0.01), chop (p < 0.01), and poor shots (p < 0.05). Therefore, shot characteristics in table tennis matches are match period related, and the main differences existed between the beginning and the ending period. From initial to ending period, the frequency of applying the middle long placements is decreasing. At the end of every set, the players adopted a safe stroke position, performed offensive stroke types and deployed flexible stroke placement. Results suggested that coaches can establish different scenarios on the basis of varying match periods for players’ training.

714 UTILITY, TECHNIQUES, AND OUTCOMES FOR THORACIC DRAINAGE AFTER OESOPHAGECTOMY: A SYSTEMATIC REVIEW

The routine use of post-operative drains in surgery continues to evolve as part of modern practices. Modern enhanced recovery protocols eschew using abdominal drains due to their impact on patient comfort, mobility, and recovery. This change in practice has not applied to thoracic drainage after oesophagectomy, where one or multiple drains are routinely placed. The aim of this study was to determine the evidence for, and how best to use drains during oesophageal surgery. Methods A systematic literature search was performed in Medline, Embase and Cochrane collaboration databases until Jan 25th, 2021. All studies which compared outcomes for different types or uses of thoracic drainage, or reported outcomes directly related to chest drains in oesophageal surgery were included. Studies were collated into domains based on variations in number, position, type, removal criteria, diagnostic use and complications of drains. Methodological quality was assessed by the Newcastle-Ottawa and Jadad Scores. Results 28 studies met the inclusion criteria. Four studies compared drain numbers, three showed similar outcomes and pain reduction using one. A single study showed that another, ‘anastomotic drain’ aided diagnosis and reduced leak mortality. Transhiatal drains had less pain and similar outcomes compared to intercostal drains. Drain fluid amylase aids leak diagnosis, however, accuracy requires drains to remain for 6 days. Removal of drains with daily volumes of less than 300 mL did not impact effusion rate. Complications can arise from drains with a 7% chance of drains migrating into the lumen of a leak and a risk of drain-site metastasis. Conclusion Drain use is a small facet of oesophageal surgery that can have a significant impact on outcomes. There is no evidence for non-drain use. A single transhiatal drain reduces pain without impacting on outcomes. Drains can have a role in diagnosing and managing anastomotic leaks, however, to be accurate drains have to stay in situ for longer. This extends patients discomfort and moves away from ERP trends and other surgical specialities.

Characterizing adaptations of serve indicators in top-level male volleyball among seasons

The purpose of this study was to analyse selected serve characteristics in top-level male volleyball, with a special focus on detecting adaptations of the serve skill among seasons. The indicators examined were type, position, direction and quality of serve. The sample consisted of 5482 serves from three final phases of different top-level tournaments (Olympic Games 2012, N = 1942, World League 2017, N = 1883, World Championship 2018, N = 1657). The interrelationships between variables were analyzed using chi-squared tests, log-linear modelling and multiple correspondence analysis. The results showed that the interaction of all serve indicators are statistically important, but the combination of the variables’ categories that were more responsible for association alternated across the seasons under study. A 3-way association term was revealed for season 2012 (type/position/direction) and 2018 (type/position/quality), while for season 2017 multiple 2-way interactions were found (type/position, type/direction, position/quality, direction/quality). The direction of the serve to the horizontal axis of the court was correlated to the quality of serve and consequently with the advantage of the serving team, while a more tactical perspective for serve skill is formed over periods in top level male volleyball.

A Conversation Analysis of Repair Trouble Sources, Inadequacy and Positions in the Iraqi University Viva Discussions in English

Oral interaction is sometimes not articulated by its participants as perfect as they project. The unsuccessful instances of talk in exchange may cause serious communicative breakdowns between the involved partners of the interactive activity. Conversation analysis (CA) is privileged to have a powerful mechanism, which is called repair organization that is exploited in interaction to prevent and fix any variety of troubles in talk. This strategic organization of repair is then operated to capacitate talkers of unavoidable interactive breakdowns of talk. Accordingly, this study aims at observing, describing, analyzing and identifying the trouble sources of repair strategies which exist in the Iraqi university viva discussions in English, and investigating their repair positions and inadequacies. Likewise, it is hypothesized that misunderstanding errors is the most frequent trouble source of repairs in the Iraqi university viva discussions in English, non-repair is the most frequent repair inadequacy, and that the fourth position of repair is the most frequent position type. The procedure adopted to fulfil the aims and to verify the hypotheses include collecting data which consists of four hours and ten minutes of audiotaped oral interactions in the MA and Ph.D. viva discussions, developing a model for repair strategies from various theories in CA, observing and collecting the data by recording audiotaped samples of those interactions in viva discussions as sample of the study, putting the datasets into orthography, calculating and describing by the use of the model, and analyzing the dataset of the study qualitatively and quantitatively. The study concludes that the eclectic model suggested and applied in the study gives a multi- faceted description of the different repair study. It is found that repair sources of trouble include grammar, vocabulary, pronunciation, discourse, factual information, channel, processing, misunderstanding errors, repair of no errors. It also exposes that there are zero occurrence of miss-repair, self-repair and other-repair failures, that pronunciation trouble source of repair results in the highest occurrences and that factual information and repair of no errors are the least frequent trouble sources. The study reveals that non-repair is the most frequent repair inadequacy and same turn repair position is the most frequent one.

Academics’ preferences for office spaces

Purpose This paper aims to investigate preferences for office spaces among academic staff at a university. The authors consider differences across age groups, seniority, position type and current office situation. Design/methodology/approach This paper is an empirical investigation of survey data using descriptive statistics and regression analyses. The sample consists of 485 academic employees at the Norwegian University of Science and Technology. Findings Staff in individual offices are substantially more satisfied with their office space than those who share office space. Moreover, those in large offices are more satisfied than those in smaller. Large offices are occupied by staff with high seniority, and staff with large offices tend to host meetings more frequently than their colleagues. However, it is not clear whether differences in office spacing reflect real needs or mostly status. Originality/value Understanding which office spaces that stimulate the best research and higher education is of great importance when policy makers plan resource allocation.

High-Resolution Coherency Functionals for Improving the Velocity Analysis of Ground-Penetrating Radar Data

We aim at verifying whether the use of high-resolution coherency functionals could improve the signal-to-noise ratio (S/N) of Ground-Penetrating Radar data by introducing a variable and precisely picked velocity field in the migration process. After carrying out tests on synthetic data to schematically simulate the problem, assessing the types of functionals most suitable for GPR data analysis, we estimated a varying velocity field relative to a real dataset. This dataset was acquired in an archaeological area where an excavation after a GPR survey made it possible to define the position, type, and composition of the detected targets. Two functionals, the Complex Matched Coherency Measure and the Complex Matched Analysis, turned out to be effective in computing coherency maps characterized by high-resolution and strong noise rejection, where velocity picking can be done with high precision. By using the 2D velocity field thus obtained, migration algorithms performed better than in the case of constant or 1D velocity field, with satisfactory collapsing of the diffracted events and moving of the reflected energy in the correct position. The varying velocity field was estimated on different lines and used to migrate all the GPR profiles composing the survey covering the entire archaeological area. The time slices built with the migrated profiles resulted in a higher S/N than those obtained from non-migrated or migrated at constant velocity GPR profiles. The improvements are inherent to the resolution, continuity, and energy content of linear reflective areas. On the basis of our experience, we can state that the use of high-resolution coherency functionals leads to migrated GPR profiles with a high-grade of hyperbolas focusing. These profiles favor better imaging of the targets of interest, thereby allowing for a more reliable interpretation.
