IntroductionThe ParticipACTION Report Card on Physical Activity for Children and Youth is the most comprehensive national assessment of physical activity and related behaviors, characteristics, and opportunities for children and youth. The 2022 Report Card assigned grades based on data gathered during the COVID-19 pandemic to reflect this extraordinary time-period in Canada. Further, while not graded, efforts were made to summarize key findings for early years children and those identifying as: having a disability, Indigenous, 2SLGBTQ+, newcomers to Canada, racialized, or girls. The purpose of this paper is to summarize the 2022 ParticipACTION Report Card on Physical Activity for Children and Youth.MethodsThe best available physical activity data captured during the whole COVID-19 pandemic was synthesized across 14 different indicators in four categories. The 2022 Report Card Research Committee assigned letter grades (i.e., A–F) based on expert consensus of the evidence.SynthesisGrades were assigned for: Daily Behaviors (Overall Physical Activity: D; Active Play: D−; Active Transportation: C−; Organized Sport: C+; Physical Education: Incomplete [INC]; Sedentary Behaviors: F; Sleep: B; 24-Hour Movement Behaviors: F), Individual Characteristics (Physical Literacy: INC; Physical Fitness: INC), Spaces and Places (Household: C, School: B−, Community and Environment: B), and Strategies and Investments (Government: B−). Compared to the 2020 Report Card, the COVID-19 specific grades increased for Active Play and Active Transportation; and decreased for Overall Physical Activity, Sedentary Behaviors, Organized Sport, and Community and Environment. There were many data gaps for equity-deserving groups.ConclusionDuring the COVID-19 pandemic, the grade for Overall Physical Activity decreased from a D+ (2020) to a D, coinciding with decreases in grades reflecting fewer opportunities for sport and community/facility-based activities as well as higher levels of sedentary behaviors. Fortunately, improvements in Active Transportation and Active Play during COVID-19 prevented a worse shift in children’s health behaviors. Efforts are needed to improve physical activity for children and youth during and post-pandemic, with a greater emphasis on equity-deserving groups.

BackgroundMost existing prognostic models of COVID-19 require imaging manifestations and laboratory results as predictors, which are only available in the post-hospitalization period. Therefore, we aimed to develop and validate a prognostic model to assess the in-hospital death risk in COVID-19 patients using routinely available predictors at hospital admission.MethodsWe conducted a retrospective cohort study of patients with COVID-19 using the Healthcare Cost and Utilization Project State Inpatient Database in 2020. Patients hospitalized in Eastern United States (Florida, Michigan, Kentucky, and Maryland) were included in the training set, and those hospitalized in Western United States (Nevada) were included in the validation set. Discrimination, calibration, and clinical utility were evaluated to assess the model's performance.ResultsA total of 17 954 in-hospital deaths occurred in the training set (n = 168 137), and 1,352 in-hospital deaths occurred in the validation set (n = 12 577). The final prediction model included 15 variables readily available at hospital admission, including age, sex, and 13 comorbidities. This prediction model showed moderate discrimination with an area under the curve (AUC) of 0.726 (95% confidence interval [CI]: 0.722—0.729) and good calibration (Brier score = 0.090, slope = 1, intercept = 0) in the training set; a similar predictive ability was observed in the validation set.ConclusionAn easy-to-use prognostic model based on predictors readily available at hospital admission was developed and validated for the early identification of COVID-19 patients with a high risk of in-hospital death. This model can be a clinical decision-support tool to triage patients and optimize resource allocation.

IntroductionRisk factors for noncommunicable diseases such as insufficient physical activity (PA), overweight or hypertension are becoming increasingly predominant among children globally. While school-based interventions are promising preventive strategies, evidence of their long-term effectiveness, especially among vulnerable populations, is scarce. We aim to assess the short-term effects of the physical and health KaziKidz intervention on cardiometabolic risk factors and the long-term, pre-and post-COVID-19 pandemic changes thereof in high-risk children from marginalized communities.MethodsThe intervention was tested in a cluster-randomized controlled trial between January and October 2019 in eight primary schools near Gqeberha, South Africa. Children with overweight, elevated blood pressure, pre-diabetes, and/or borderline dyslipidemia were identified and re-assessed 2 years post-intervention. Study outcomes included accelerometry-measured PA (MVPA), body mass index (BMI), mean arterial pressure (MAP), glucose (HbA1c), and lipid levels (TC to HDL ratio). We conducted mixed regression analyses to assess intervention effects by cardiometabolic risk profile, and Wilcoxon signed-rank tests to evaluate longitudinal changes in the high-risk subpopulation.ResultsWe found a significant intervention effect on MVPA during school hours for physically inactive children, and among active as well as inactive girls. In contrast, the intervention lowered HbA1c and TC to HDL ratio only in children with glucose or lipid values within the norm, respectively. At follow-up, the intervention effects were not maintained in at-risk children, who showed a decline in MVPA, and an increase in BMI-for-age, MAP, HbA1c and TC to HDL ratio.ConclusionWe conclude that schools are key settings in which to promote PA and improve health; however, structural changes are necessary to ensure that effective interventions reach marginalized school populations and achieve sustainable impact.
A Novel Automated Model for Evaluation of the Efficiency of Hole Cleaning Conditions during Drilling Operations

Published: May 2023

Hole cleaning for the majority of vertical and directional drilling wells continues to be a substantial difficulty despite improvements in drilling fluids, equipment, field techniques, and academic and industrial research. Poor hole cleaning might cause issues such as stuck pipe incidents, drilling cuttings accumulation, torque and drag, the erratic equivalent circulating density in the annulus, wellbore instability, tight spots, and hole condition issues. In order to enable the real-time and automated evaluation of hole cleaning efficiency for vertical and directional drilling, the article’s objective is to develop a novel model for the cutting transport ratio (CTRm) that can be incorporated into drilling operations on a real-time basis. The novel CTRm model provides a robust indicator for hole cleaning, which can assess complications and enhance drilling efficiency. Moreover, the novel CTRm model was successfully tested and validated in the field for four wells. The results of the real-time evaluation showed that the novel model was capable of identifying the hole cleaning efficiency in a normal drilling performance for Well-C and a stuck pipe issue in Well-D. In addition, the novel CTRm improved the rate of penetration by 52% in Well-A in comparison to Well-B.
Tourism and Marginalization in the Alps. The Case of Media-Alta Valtellina Region
Authors: Mazza Francesca 
Published: May 2023

Tourism and marginalization are broadly considered different trajectories in the Alpine region's development. On the one hand, tourism is one of the main economic drivers in the Alps. However, many areas still depend on a mass tourism economy that produces relevant ecological, sociocultural and economic impacts. At the same time, marginalization identifies those contexts excluded by mass tourism development affected by shrinkage, abandonment and economic decline. Within this framework, the paper points out that these processes often overlap and coexist, producing complex and layered spatial geographies. The Media-Alta Valtellina Region, located in the Lombard Italian Alps, is provided as a case study to investigate the relationship between mass tourism and marginalization through two sets of indicators. Tourism indicators measure the impact of mass tourism development, while territorial capital indicators assess marginalization processes and the potential expressed by environmental, productive, demographic, infrastructural, settlement, and cultural resources. As a result, besides popular mass tourism poles and non-touristic marginalized areas, several mature tourism destinations emerge where marginalization effects and mass tourism issues overlap. Furthermore, territorial capital broadly appears as the intrinsic potential that must be activated and valorized to build new development trajectories. In conclusion, according to the different potentials expressed by territorial capital, the paper provides preliminary suggestions and guidelines for achieving the territorial rebalance between the multiple processes investigated.

Authors: Silva Cândida , Silva Susana , Rodrigues Bruna 
Published: May 2023

The evolution of social media has transformed the way people communicate, share experiences and search for information before and after a trip. These platforms can bring countless benefits to businesses but implementing them effectively brings countless challenges.
In the hotel industry, the use of social media as a digital marketing strategy has become fundamental to promote brands and services, as well as to create a closer relationship with the customer. It then becomes essential to understand how hotels can use these platforms effectively. Moreover, defining communication strategies, especially in periods of global crisis, with customers and public that include social networks are fundamental and a great challenge.
In this sense, in this paper a case study of a hotel in a period including the global pandemic crisis of COVID-19 was conducted where good practices for social media management in hospitality are proposed, supported by the literature review and the practical learning provided in the fieldwork. These good practices also take into consideration the application of successful social media strategies in a hotel during times of crisis.

Communication is an essential part to achieve the goals of any organization. Thus, nowadays, many organizations are committed to have an appropriate communication flow, being of total obligation to provide their collaborators with the necessary tools for an assertive communication; therefore, if the collaborators perceive that the institution offers them value, they will show great commitment to the achievement of the goals, based on internal communication. The government institution under study, which manages tourism in a region of Peru, presents several problems related to the organizational climate and its factors, such as lack of cooperation, poor relations between employees, conflicts and poor communication, which causes low productivity by the institution. The general objective is to determine the relationship between the organizational climate of the Regional Management of Foreign Trade and Tourism of Lambayeque and the impact on the achievement of the institution's objectives. Its variables seek to know if there is a relationship between organizational climate and the impact on the achievement of goals. Likewise, in relation to the methodology, it was a quantitative study, the method used was inductive and deductive, with a non-experimental design of correlational cross-sectional cut. Its population consisted of 35 workers of the Regional Management of Foreign Trade and Tourism of Lambayeque, and its sample was a census, since it worked with the entire population and had a non-probabilistic sampling, of these correspond to 19 males and 16 females. Likewise, in terms of techniques and instruments, a survey was used, and a questionnaire was used as an instrument for both variables. As the main result, when applying Spearman's Rho, a value of 0.872 was obtained, which indicates that there is a strong and positive relationship between organizational climate and goal fulfillment. In view of the above, it has been concluded that there is a significant relationship between organizational climate and goal achievement.
What do hotel managers think of employee rewards? An exploration of five-star hotels in Cape Town
Authors: Cwibi Mzukisi 
Published: May 2023

Reward systems are important tools that management can use to motivate employees; the main objective of organizations in awarding rewards is to attract and retain efficient, productive, and motivated employees. However, there is no evidence available regarding managers' perceptions of employee rewards in five-star hotels in Cape Town. Therefore, this study aims to explore the perceptions of five-star hotel managers about the reward systems offered to employees. Further, this paper attempts to explore the influence and impact of the covid-19 pandemic on the employee reward systems offered at five-star hotels. A total of 14 interviews were conducted with managers working in four selected five-star hotels. The study used semi-structured interviews to collect qualitative data. The data were analysed using Creswell’s six steps. The study's findings indicate that managers offered distinct types of rewards to their employees, including extrinsic and intrinsic rewards. Managers revealed that extrinsic rewards, specifically money, are the most preferred rewards. The study revealed that the impact of the Covid-19 pandemic led to hotels adjusting their employee reward systems to offer less extrinsic rewards and more intrinsic rewards. This paper concludes by recommending strategies to hotel management for enhancing the type of rewards offered to employees and offering utilisation of effective intrinsic rewards. This is to ensure that employees increase their value towards intrinsic rewards as much as they value extrinsic rewards Implications for future research are also presented.

The Covid-19 pandemic impacted the world economies. Among the most affected sectors is the service sector, with the tourism segment standing out. Museums, parks, theatres, and tourist monuments had a great challenge with the period of social detachment. Digital transformation was the way adopted by companies to connect with their audiences and, consequently, contribute to the different segments of the value chain such as accommodation, transport and leisure and recreation. Thus, the managers of tourist attractions bet on entrepreneurial actions supported by digital transformation to change the business model in the face of the new pandemic scenario. The literature is still scarce to explore these actions adopted by museums worldwide. Thus, the research aims to identify the actions related to digital transformation adopted by museums in Ouro Preto during the pandemic period and compare them with the actions adopted by other museums around the world. Ouro Preto is a historical city of Brazil, conferred by Unesco. These museums are one of the main attractions of the city, whose economy is anchored in this segment of the service sector. This research comprises a Systematic Literature Review, using the PRISMA method. The literature served as a basis for the preparation of the protocol for collecting information from museums in Ouro Preto, guiding the comparative study of the actions practiced by them and compared with actions in the world. The study identifies the digital presence of museums on social platforms and verifies the reaction of these organisations to the pandemic. The information was collected in 12 museums. The protocol was answered through secondary data published on Facebook, Twitter, Instagram and digital platforms used by the museums. The results show differences between the strategies of Ouro Preto museums and other museums. It was observed that Ouro Preto museums adopted a more passive strategy when compared to the strategies adopted by other museums in the world. This result demonstrates the lack of an improvement agenda of adopting advanced technologies to increase the added value of museums.

Abstract
In this study, a high critical temperature (high-T
c) superconducting flux transformer is prepared using a commercially available REBa2Cu3O
y
(REBCO) high-T
c superconducting (HTS) tape conductor. The device configuration includes a 10 cm diameter pickup coil and a 3 cm diameter multi-turn input coil, which are formed by the “cut-and wind” method. The static magnetic field transfer efficiency between both coils has been estimated using inductance calculation of the multi-turn coils. The transfer efficiency measured is close to the calculation, and the field amplification of the transferred magnetic field compared to the applied field to the pickup coil is confirmed in the device which equipped with the multi-turn input coil. The magnitude of this magnetic field amplification has achieved to 125% of the applied field. This result suggests that the HTS flux transformer proposed in this study is effective in the sensitivity enhancement of the magnetometer for static magnetic fields.
