Social Sustainability: the challenges to the restaurant sector
Authors: Maia Beatriz , Silva Susana , Melo António 
Published: March 2024

The guarantee of sustainable development has been a growing concern in various economic sectors, particularly from the economic and environmental perspective. In a post-pandemic scenario, the restaurant industry was one of the most affected worldwide and had to undergo abrupt changes to remain operational. Thus, this study primarily focuses on addressing the challenges faced by Human Resources Management (HRM) in attracting and retaining employees in the restaurant sector. This research aims to understand the challenges faced in retaining and attracting talent to restaurants and to explore the strategies that should be adopted to ensure the restaurant’s social. It used a qualitative methodology, with 10 (5 female and 5 male, with a mean age of 35 years old) semi-structured interviews with professionals who chose to leave this profession, to ensure a concerted view of the current state of the sector in the north of Portugal. Through thematic analysis of the interviews, the results identified the current difficulties in attracting and retaining employees in the sector, as well as some HRM strategies that can address these challenges. These findings emerged from the themes 'Special Features of the Restaurant Sector' and 'Attraction and Retention Strategies.' The first theme contextualizes and characterizes the sector's reality, arising from four categories: activity context, company type, the COVID-19 pandemic, and turnover factors. Meanwhile, the second theme presents the attraction and retention strategies that HRM in restaurant companies should implement, while also exploring some challenges faced in designing and implementing these strategies in practice. Specifically, recruitment and selection, compensation and benefits, onboarding, integration and socialization, and career management. In conclusion, social sustainability still has little prominence in the restaurant sector. To become more attractive, the restaurant sector needs to invest in better non-monetary benefits, such as flexible working hours, health insurance, professional recognition, training investment, and career advancement opportunities. This study intends to help companies take measures to improve employee satisfaction and also increase talent retention and new employees’ attraction.
Unlocking the Potential of Hybrid Learning: Tourism Student Voices in South African Universities of Technology

Published: March 2024

This article examines the impacts the pandemic learning environment had on student learning and wellness, and how rethinking higher education (HE) design could bolster the improved student well-being. In the wake of Covid-19, academia is searching for some “normalcy” which requires a critical review of the suitability of current structures, as policy design struggles with the possibilities of a hybrid approach to pedagogic delivery. The body of knowledge on blended/hybrid learning design requires the student voice, in cold face experiences of pandemic-induced academic evolution, to get closer to discovering a model that benefits both teaching and learning. The unearthing of possible unrealised disruptions to the learning environment, affecting social, personal and cognitive presence. A sequential explanatory study that included the collection of quantitative survey data, and qualitative focus group interviews was conducted. The census enquiry of tourism management students at three universities of technology in South Africa was concluded online, as per remote learning requirements at the height of the pandemic. Study results indicate that remote learning during the Covid-19 pandemic impacted negatively on student learning and mental health at universities of technology (UOTs) in South Africa. Student data indicated that even through strict pandemic regulations, the university campus life morphed, and did not die. Students gravitated towards parts of the campus considered soothing, with proper internet access, arguing for a holistic, sustainable university architecture that bolsters learning and student support. HE institutions need to further consider the role and design of university architecture for hybrid/blended learning, with a user-focused perspective.

Гемифациальный спазм (ГФС) – заболевание, проявляющееся безболезненными пароксизмальными непроизвольными односторонними тоническими или клоническими сокращениями лицевой мускулатуры, иннервируемой ипсилатеральным лицевым нервом. Частота встречаемости ГФС составляет примерно 11 на 100 000 населения, при этом заболевание манифестируется в среднем в районе третьего десятка жизни пациента. Гемифациальный спазм подразделяется на первичный, когда наличие спазмов обусловлено нейроваскулярным конфликтом в области лицевого нерва, и вторичный, когда наличие фасцикуляций лицевой мускулатуры обусловлено другими причинами. Первичный гемифациальный спазм чаще всего возникает из-за сдавления лицевого нерва артерией (передней нижней мозжечковой, задней нижней мозжечковой, позвоночной), реже венозными сосудами в области выхода нерва из ствола головного мозга. Учитывая распространенность гемифациального спазма, поражение преимущественно пациентов молодого возраста, инвалидизирующий характер заболевания, изучение этиологии, патогенеза, анатомических осбенностей первичного ГФС является актуальной проблемой современной нейрохирургии.
Hemifacial spasm (HFS) is a disease manifested by painless paroxysmal involuntary unilateral tonic or clonic contractions of the facial muscles innervated by the ipsilateral facial nerve. The incidence of HFS is approximately 11 per 100,000 population, and the disease manifests itself on average around the third decade of the patient’s life. Hemifacial spasm is divided into primary – when the presence of spasms is due to a neurovascular conflict in the area of the facial nerve and secondary – when the presence of fasciculations of the facial muscles is due to other reasons. Primary hemifacial spasm most often occurs due to compression of the facial nerve by an artery (anterior inferior cerebellar, posterior inferior cerebellar, vertebral artery), less often – by venous vessels in the area where the nerve exits the brain stem. Considering the prevalence of hemifacial spasm, the affection of predominantly young patients, the disabling nature of the disease, the study of the etiology, pathogenesis, and anatomical features of primary HFS is an urgent problem of modern neurosurgery.

Analyser les discours institutionnels (1998-2019) : posture de recherche et questionnement éthique
Authors: Mahmoudi Kaltoum 
Published: March 2024

Ce texte a pour objectif d’interroger la posture de l’analyste de discours face à son objet de recherche qui l’implique sur le terrain professionnel. Professeure documentaliste et docteure en SIC, l’objectif de notre thèse fut de mettre au jour la force d’évidence de la formule « esprit critique » et les schèmes idéologiques qui soutiennent son usage dans les discours institutionnels. Une finalité de cette recherche doctorale vise à interroger la dimension critique de cette culture telle qu’elle est perçue dans les discours institutionnels et ce, à partir d’une approche interdisciplinaire et au moyen d’une analyse de trois corpus de discours couvrant 21 années (1998-2019). En retraçant les étapes qui ont jalonné ce parcours de recherche, nous soulèverons les questionnements d’ordre éthique inhérents à la posture de « praticienne- chercheuse », expression empruntée à Catherine De Lavergne (2007). Entre prétendue neutralité descriptive comme gage de scientificité et positionnement critique de la praticienne impliquée, quelle posture éthique pour l’analyste de discours ?
Ideals with componentwise linear powers
Authors: Hibi Takayuki , Moradi Somayeh 
Published: March 2024

AbstractLet
$S=K[x_1,\ldots ,x_n]$
be the polynomial ring over a field K, and let A be a finitely generated standard graded S-algebra. We show that if the defining ideal of A has a quadratic initial ideal, then all the graded components of A are componentwise linear. Applying this result to the Rees ring
$\mathcal {R}(I)$
of a graded ideal I gives a criterion on I to have componentwise linear powers. Moreover, for any given graph G, a construction on G is presented which produces graphs whose cover ideals
$I_G$
have componentwise linear powers. This, in particular, implies that for any Cohen–Macaulay Cameron–Walker graph G all powers of
$I_G$
have linear resolutions. Moreover, forming a cone on special graphs like unmixed chordal graphs, path graphs, and Cohen–Macaulay bipartite graphs produces cover ideals with componentwise linear powers.
The effective reproduction number: Convexity, concavity and invariance
Authors: Delmas Jean-François , Dronnier Dylan , Zitt Pierre-André 
Published: March 2024

Motivated by the question of optimal vaccine allocation strategies in heterogeneous population for epidemic models, we study various properties of the
effective reproduction number
. In the simplest case, given a fixed non-negative matrix

K

, this corresponds mathematically to the study of the spectral radius

R_{e}(\eta)

of the matrix product

\mathrm{Diag}(\eta)K

, as a function of

\eta \in \mathbb{R}_{+}^{n}

. The matrix

K

and the vector

\eta

can be interpreted as a next-generation operator and a vaccination strategy. This can be generalized in an infinite-dimensional case where the matrix

K

is replaced by a positive integral compact operator, which is composed with a multiplication by a non-negative function

\eta

. We give sufficient conditions for the function

R_{e}

to be convex or a concave. Eventually, we provide equivalence properties on models which ensure that the function

R_{e}

is unchanged.
Wreath products of groups acting with bounded orbits
Authors: Leemann Paul-Henry , Schneeberger Grégoire 
Published: March 2024

If

\mathbf{S}

is a subcategory of metric spaces, we say that a group

G

has property

\mathrm{B}\mathbf{S}

if any isometric action on an

\mathbf{S}

-space has bounded orbits. Examples of such subcategories include metric spaces, affine real Hilbert spaces,

\operatorname{CAT}(0)

cube complexes, connected median graphs, trees or ultra-metric spaces. The corresponding properties

{\mathrm{B}\mathbf{S}}

are respectively Bergman’s property, property

\mathrm{FH}

(which, for countable groups, is equivalent to the celebrated Kazhdan’s property

\textup{(T)}

), property

\mathrm{FW}

(both for

\operatorname{CAT}(0)

cube complexes and for connected median graphs), property

\mathrm{FA}

and uncountable cofinality. Historically many of these properties were defined using the existence of fixed points. Our main result is that for many subcategories

\mathbf{S}

, the wreath product

G\wr_{X}H

has property

{\mathrm{B}\mathbf{S}}

if and only if both

G

and

H

have property

{\mathrm{B}\mathbf{S}}

and

X

is finite. On one hand, this encompasses in a general setting previously known results for properties

\mathrm{FH}

and

\mathrm{FW}

. On the other hand, this also applies to the Bergman’s property. Finally, we also obtain that

G\wr_{X}H

has uncountable cofinality if and only if both

G

and

H

have uncountable cofinality and

H

acts on

X

with finitely many orbits.
Efficacy and safety of perioperative therapy for locally resectable gastric cancer: A network meta-analysis of randomized clinical trials
Authors: Kuang Zi-Yu , Sun Qian-Hui , Cao Lu-Chang , Ma Xin-Yi , Wang Jia-Xi , Liu Ke-Xin , Li Jie 
Published: March 2024

BACKGROUND
Gastric cancer (GC) is the fifth most commonly diagnosed malignancy worldwide, with over 1 million new cases per year, and the third leading cause of cancer-related death.
AIM
To determine the optimal perioperative treatment regimen for patients with locally resectable GC.
METHODS
A comprehensive literature search was conducted, focusing on phase II/III randomized controlled trials (RCTs) assessing perioperative chemotherapy and chemoradiotherapy in treating locally resectable GC. The R0 resection rate, overall survival (OS), disease-free survival (DFS), and incidence of grade 3 or higher nonsurgical severe adverse events (SAEs) associated with various perioperative regimens were analyzed. A Bayesian network meta-analysis was performed to compare treatment regimens and rank their efficacy.
RESULTS
Thirty RCTs involving 8346 patients were included in this study. Neoadjuvant XELOX plus neoadjuvant radiotherapy and neoadjuvant CF were found to significantly improve the R0 resection rate compared with surgery alone, and the former had the highest probability of being the most effective option in this context. Neoadjuvant plus adjuvant FLOT was associated with the highest probability of being the best regimen for improving OS. Owing to limited data, no definitive ranking could be determined for DFS. Considering nonsurgical SAEs, FLO has emerged as the safest treatment regimen.
CONCLUSION
This study provides valuable insights for clinicians when selecting perioperative treatment regimens for patients with locally resectable GC. Further studies are required to validate these findings.
Impact of Alcian blue and periodic acid Schiff expression on the prognosis of gastric signet ring cell carcinoma
Authors: Lin Juan , Chen Zhu-Feng , Guo Guo-Dong , Chen Xin 
Published: March 2024

BACKGROUND
The Alcian blue (AB) and periodic acid Schiff (PAS) stains are representative mucus markers in gastric signet ring cell carcinoma (SRCC). They are low-cost special staining methods used to detect acidic mucus and neutral mucus, respectively. However, the clinical importance of the special combined AB and PAS stain is unclear.
AIM
To investigate AB expression, PAS expression and the AB-to-PAS (A/P) ratio in gastric SRCC patients and to assess patient prognosis.
METHODS
Paraffin-embedded sections from 83 patients with gastric SRCC were stained with AB and PAS, and signet ring cell positivity was assessed quantitatively. Immunohistochemical staining for Ki67, protein 53 (P53) and human epidermal growth factor receptor 2 (HER2) was performed simultaneously. The cancer-specific survival (CSS) rate was estimated via Kaplan-Meier analysis. Cox proportional hazards models were used for univariate and multivariate survival analyses.
RESULTS
Kaplan-Meier survival analysis revealed that the 3-year CSS rate was significantly greater in the high-PAS-expression subgroup than in the low-PAS-expression subgroup (P < 0.001). The 3-year CSS rate in the A/P ≤ 0.5 group was significantly greater than that in the A/P > 0.5 group (P = 0.042). Univariate Cox regression analysis revealed that the factors affecting prognosis included tumor diameter, lymph node metastasis, vessel carcinoma embolus, tumor stage, the A/P ratio and the expression of Ki67, P53 and the PAS. Cox multivariate regression analysis confirmed that low PAS expression [hazard ratio (HR) = 3.809, 95% confidence interval (CI): 1.563-9.283, P = 0.003] and large tumor diameter (HR = 2.761, 95%CI: 1.086-7.020, P = 0.033) were independent risk factors for poor prognosis.
CONCLUSION
A/P > 0.5 is potentially a risk factor for prognosis, and low PAS expression is an independent risk factor in the prognosis of gastric SRCC. PAS expression and the A/P ratio could help in predicting the clinical prognosis of patients with SRCC.

BACKGROUND
Pancreatic ductal adenocarcinoma (PDAC) is a common cancer with increasing morbidity and mortality due to changes of social environment.
AIM
To evaluate the significance of serum carbohydrate antigen 19-9 (CA19-9) and tumor size changes pre- and post-neoadjuvant therapy (NAT).
METHODS
This retrospective study was conducted at the Chongqing Key Laboratory of Translational Research for Cancer Metastasis and Individualized Treatment, Chongqing University Cancer Hospital. This study specifically assessed CA19-9 levels and tumor size before and after NAT.
RESULTS
A total of 156 patients who completed NAT and subsequently underwent tumor resection were included in this study. The average age was 65.4 ± 10.6 years and 72 (46.2%) patients were female. Before survival analysis, we defined the post-NAT serum CA19-9 level/pre-NAT serum CA19-9 level as the CA19-9 ratio (CR). The patients were divided into three groups: CR < 0.5, CR > 0.5 and < 1 and CR > 1. With regard to tumor size measured by both computed tomography and magnetic resonance imaging, we defined the post-NAT tumor size/pre-NAT tumor size as the tumor size ratio (TR). The patients were then divided into three groups: TR < 0.5, TR > 0.5 and < 1 and TR > 1. Based on these groups divided according to CR and TR, we performed both overall survival (OS) and disease-free survival (DFS) analyses. Log-rank tests showed that both OS and DFS were significantly different among the groups according to CR and TR (P < 0.05). CR and TR after NAT were associated with increased odds of achieving a complete or near-complete pathologic response. Moreover, CR (hazard ratio: 1.721, 95%CI: 1.373-3.762; P = 0.006), and TR (hazard ratio: 1.435, 95%CI: 1.275-4.363; P = 0.014) were identified as independent factors associated with OS.
CONCLUSION
This study demonstrated that post-NAT serum CA19-9 level/pre-NAT serum CA19-9 level and post-NAT tumor size/pre-NAT tumor size were independent factors associated with OS in patients with PDAC who received NAT and subsequent surgical resection.
