Older workers in the hospitality industry: valuing experience and informal learning

The research sets out to identify the learning processes adopted by older workers in the hospitality and visitor attraction industry in Scotland, with a view to determining how employers may better support their education and training within enterprises. The study was undertaken as part of the ESRC project on ‘sustaining the employability of older workers in the hospitality sector: personal learning strategies and cultures of learning. The data collection period was from 2008-2010 and focused on six case studies; three in hospitality and three visitor attraction centres. The conceptual framework of the research is based upon the simple yet important notion of experience and how this enhances the learning lives of older employees. It will be argued that the learning processes used by older employees are primarily recognisable as social practices, based upon the utilisation of existing knowledge and skills. The analysis suggests that organisations should be encouraged to avoid using a ‘one size fits all’ approach to education and training and, in the case of older workers, to make more use of their past work and life experiences in order to facilitate their own and others’ learning

Multifunctional silver-coated transparent TiO2 thin films for photocatalytic and antimicrobial applications

Transparent TiO2 thin films coated with Ag NPs were synthesized using two industrially applicable techniques, pulsed laser ablation (PLAL) and spray pyrolysis without using high vacuum. These transparent thin films were deposited on glass in order to generate glass materials with photocatalytic and antimicrobial properties and a minimum loss of transparency. The structural, morphological and optical properties of the thin films were examined using Grazing incidence X-ray diffraction (GIXRD), Raman spectroscopy, Scanning electron microscopy (SEM) and ultraviolet–visible spectroscopy. Transmission electron microscopy (TEM) was used to identify the NPs on the TiO2 surface. The transmittance value for the thin films was greater than 80%.The thin films thus synthesized were then assessed to determine their photocatalytic capacity by monitoring the degradation of Rhodamine B (RhB) under UV light irradiation. Ag NPs on the TiO2 surface ensures an improvement in the photocatalytic properties, with a 99% degradation of RhB in 210 min under UV light. In addition, these transparent thin films showed high antimicrobial activity on Gram-negative bacteria when irradiated by UV light for 4 h, killing 93% of these bacteria.Funding for open access charge: CRUE-Universitat Jaume

LES-based Study of the Roughness Effects on the Wake of a Circular Cylinder from Subcritical to Transcritical Reynolds Numbers

This paper investigates the effects of surface roughness on the flow past a circular cylinder at subcritical to transcritical Reynolds numbers. Large eddy simulations of the flow for sand grain roughness of size k/D = 0.02 are performed (D is the cylinder diameter). Results show that surface roughness triggers the transition to turbulence in the boundary layer at all Reynolds numbers, thus leading to an early separation caused by the increased momentum deficit, especially at transcritical Reynolds numbers. Even at subcritical Reynolds numbers, boundary layer instabilities are triggered in the roughness sublayer and eventually lead to the transition to turbulence. The early separation at transcritical Reynolds numbers leads to a wake topology similar to that of the subcritical regime, resulting in an increased drag coefficient and lower Strouhal number. Turbulent statistics in the wake are also affected by roughness; the Reynolds stresses are larger due to the increased turbulent kinetic energy production in the boundary layer and separated shear layers close to the cylinder shoulders.We acknowledge “Red Española de Surpercomputación” (RES) for awarding us access to the MareNostrum III machine based in Barcelona, Spain (Ref.

Managing by design

This editorial written by myself and Marc Gruber of EPFL. It explores the role of design thinking in the management of large organisations, and focuses on how design principles can be applied to the design of the workplace and the nature of work itself. As Head of Service Design at the RCA, my contribution is on how to apply design thinking methods for managers and the 6 key elements described in this approach In the last decade the importance of design and the value of design thinking as a tool for innovation has been recognized by both business and government. Design has become a strategic tool for business helping to translate technological innovation into user value, connecting with consumer needs and creating compelling product and service experiences that create new business value. In this paper we consider a further application of design thinking by considering how managers can apply it to the design of the workplace experience. Many enterprises, especially those in the knowledge economy, are defined by their human resources and their capacity to attract and retain talent. In this competitive environment the design of the employee experience and the services that support them and enable them to deliver value to the clients and colleagues, is a key differentiator. Applying design thinking to the design of work itself, the systems that support it, and the physical and virtual environments in which it takes place can help business and organizational leaders to attract and retain top talent, as well as to enhance productivity and operational effectiveness. In this paper we explore the key factors and principles by which leaders and managers can apply design thinking to transform the workplace experience and we propose 6 key elements for managers to enable that transformation and enhance social capital and business and organisational performance

Molecular profiling of circulating tumor cells links plasticity to the metastatic process in endometrial cancer

Background: About 20% of patients diagnosed with endometrial cancer (EC) are considered high-risk with unfavorable prognosis. In the framework of the European Network for Individualized Treatment in EC (ENITEC), we investigated the presence and phenotypic features of Circulating Tumor Cells (CTC) in high-risk EC patients. Methods: CTC isolation was carried out in peripheral blood samples from 34 patients, ranging from Grade 3 Stage IB to Stage IV carcinomas and recurrences, and 27 healthy controls using two methodologies. Samples were subjected to EpCAM-based immunoisolation using the CELLection™ Epithelial Enrich kit (Invitrogen, Dynal) followed by RTqPCR analysis. The phenotypic determinants of endometrial CTC in terms of pathogenesis, hormone receptor pathways, stem cell markers and epithelial to mesenchymal transition (EMT) drivers were asked. Kruskal-Wallis analysis followed by Dunn's post-test was used for comparisons between groups. Statistical significance was set at p < 0.05. Results: EpCAM-based immunoisolation positively detected CTC in high-risk endometrial cancer patients. CTC characterization indicated a remarkable plasticity phenotype defined by the expression of the EMT markers ETV5, NOTCH1, SNAI1, TGFB1, ZEB1 and ZEB2. In addition, the expression of ALDH and CD44 pointed to an association with stemness, while the expression of CTNNB1, STS, GDF15, RELA, RUNX1, BRAF and PIK3CA suggested potential therapeutic targets. We further recapitulated the EMT phenotype found in endometrial CTC through the up-regulation of ETV5 in an EC cell line, and validated in an animal model of systemic dissemination the propensity of these CTC in the accomplishment of metastasis. Conclusions: Our results associate the presence of CTC with high-risk EC. Gene-expression profiling characterized a CTC-plasticity phenotype with stemness and EMT features. We finally recapitulated this CTC-phenotype by over-expressing ETV5 in the EC cell line Hec1A and demonstrated an advantage in the promotion of metastasis in an in vivo mouse model of CTC dissemination and homing

“Savages Who Speak French”: Folklore, Primitivism and Morals in Robert Hertz

Hertz's analysis of the Alpine cult of Saint Besse apparently marks a break from his studies of death, sin and the left to folkloric studies. This analysis helps one to understand the personality of Robert Hertz. His sociological curiosity about folklore reveals his ambiguous position in social sciences at the beginning of the twentieth century. His text appears to be a variation from the Durkheimian norm, but another reading could suggest that Hertz continued and went beyond Durkheimian thought to something between sociology of the modern world and engaged socialism. Through this study, Hertz linked his political ideals, his work in ethnology and his desire for social involvement. The cult of Saint Besse perpetuated as much religious tradition as local identity. The Alpine people were presented in the text as wilful perpetuators of an ideal social order, whose loss for his contemporary city dwellers Hertz feared. The alpine Other, marked by a material and moral backwardness, represented for activist and socialist Hertz one of the paths of balanced social organization that stabilized the identity of a group across time if it fit rather well into the folkloric stereotypes of the beginning of the twentieth century. Finally, by linking events in Herz's life (e.g., the accidental Alpine death of his father), this article suggests that the legend of Saint Besse embodied several recurring motifs in Hertz' career: the accidental deaths of saint and father by falls, the military role of the saint and of Hertz himself

Outcomes of gynecologic cancer surgery during the COVID-19 pandemic: an international, multicenter, prospective CovidSurg-Gynecologic Oncology Cancer study

Background The CovidSurg-Cancer Consortium aimed to explore the impact of COVID-19 in surgical patients and services for solid cancers at the start of the pandemic. The CovidSurg-Gynecologic Oncology Cancer subgroup was particularly concerned about the magnitude of adverse outcomes caused by the disrupted surgical gynecologic cancer care during the COVID-19 pandemic, which are currently unclear. Objective This study aimed to evaluate the changes in care and short-term outcomes of surgical patients with gynecologic cancers during the COVID-19 pandemic. We hypothesized that the COVID-19 pandemic had led to a delay in surgical cancer care, especially in patients who required more extensive surgery, and such delay had an impact on cancer outcomes. Study Design This was a multicenter, international, prospective cohort study. Consecutive patients with gynecologic cancers who were initially planned for nonpalliative surgery, were recruited from the date of first COVID-19-related admission in each participating center for 3 months. The follow-up period was 3 months from the time of the multidisciplinary tumor board decision to operate. The primary outcome of this analysis is the incidence of pandemic-related changes in care. The secondary outcomes included 30-day perioperative mortality and morbidity and a composite outcome of unresectable disease or disease progression, emergency surgery, and death. Results We included 3973 patients (3784 operated and 189 nonoperated) from 227 centers in 52 countries and 7 world regions who were initially planned to have cancer surgery. In 20.7% (823/3973) of the patients, the standard of care was adjusted. A significant delay (>8 weeks) was observed in 11.2% (424/3784) of patients, particularly in those with ovarian cancer (213/1355; 15.7%; P<.0001). This delay was associated with a composite of adverse outcomes, including disease progression and death (95/424; 22.4% vs 601/3360; 17.9%; P=.024) compared with those who had operations within 8 weeks of tumor board decisions. One in 13 (189/2430; 7.9%) did not receive their planned operations, in whom 1 in 20 (5/189; 2.7%) died and 1 in 5 (34/189; 18%) experienced disease progression or death within 3 months of multidisciplinary team board decision for surgery. Only 22 of the 3778 surgical patients (0.6%) acquired perioperative SARS-CoV-2 infections; they had a longer postoperative stay (median 8.5 vs 4 days; P<.0001), higher predefined surgical morbidity (14/22; 63.6% vs 717/3762; 19.1%; P<.0001) and mortality (4/22; 18.2% vs 26/3762; 0.7%; P<.0001) rates than the uninfected cohort. Conclusion One in 5 surgical patients with gynecologic cancer worldwide experienced management modifications during the COVID-19 pandemic. Significant adverse outcomes were observed in those with delayed or cancelled operations, and coordinated mitigating strategies are urgently needed
