Purpose
This study aims to develop and validate a scale to measure stakeholders' perception of mandatory corporate social responsibility (CSR) activities in the hotel industry in India.
...Design/methodology/approach
CSR items were generated based on a qualitative approach. The underlying factorial structure of the scale is determined using exploratory factor analysis. The measurement model is verified through confirmatory factor analysis with validity checks. Additionally, the nomological and predictive validity of the proposed scale is confirmed through correlation and regression analysis.
Findings
This study proposed a three-dimensional 17-item scale comprising the environment, social and cultural domains to measure stakeholders' perception of mandatory CSR in the Indian hotel industry.
Research limitations/implications
This study adds to the literature by providing a comprehensive approach incorporating CSR activities specified by law on CSR measurement. Validated CSR scales are recommended for future studies to measure CSR in India. This study may also serve as a blueprint for other countries to develop context-specific CSR measurement approaches.
Originality/value
To the best of the authors’ knowledge, this is the first scale development study on mandatory CSR in India. The inclusion of CSR activities prescribed by law on the standardized CSR scale development is a novel outlook.

Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma characterized by a conglomerate of clinically aggressive course and disparate histopathological features. It is ...frequently seen in upper aerodigestive tract area. Histopathologically, it is biphasic and composed of two types of tumor cells, namely basaloid and squamous cells. Tumor markers, namely, BerEp4, epithelial membrane antigen and p53 are used in this case to differentiate from similar tumors which impersonate BSCC histologically but differ prognostically. We report a case of BSCC in a 48-year-old female patient, involving the lateral border of the tongue with an exhaustive picture of its histological and immunohistochemical appearance.
Abstract
Friction stir welding (FSW) was conducted on 5754-H111 aluminium alloy using a response surface methodology to examine the impact of process parameters on the efficiency of the weld. The key ...FSW parameters were the percentage of scandium inclusion in the interlayer, tool rotational speed, and tool travel speed. The significant responses were identified as the tensile strength of the weld and the hardness in the weld zone. An Al-Mg-Sc alloy was employed as an interlayer material between the 5754 plates to enhance the strength in the weld zone. The addition of Scandium had a more pronounced effect on the hardness of the stir zone. The tensile strength was increased by raising the tool’s rotational speed. The results showed that the maximum tensile strength of the joints was 225 MPa and the hardness was highest at 118 HV1 in the weld stir zone. The introduction of Scandium improved the joint strength by producing fine grains and Al

Sc precipitates. The welding speed had the least impact on the tensile properties of the joint among all the variables investigated.
Nonlinear optical processes at soft x-ray wavelengths have remained largely unexplored due to the lack of available light sources with the requisite intensity and coherence. Here we report the ...observation of soft x-ray second harmonic generation near the carbon K edge (∼284 eV) in graphite thin films generated by high intensity, coherent soft x-ray pulses at the FERMI free electron laser. Our experimental results and accompanying first-principles theoretical analysis highlight the effect of resonant enhancement above the carbon K edge and show the technique to be interfacially sensitive in a centrosymmetric sample with second harmonic intensity arising primarily from the first atomic layer at the open surface. This technique and the associated theoretical framework demonstrate the ability to selectively probe interfaces, including those that are buried, with elemental specificity, providing a new tool for a range of scientific problems.
Everyone today actively uses online social networks to get in touch with their friends, for career opportunities, and business also. Some of the most popular social networks are Facebook, Instagram, ...LinkedIn, and Twitter. But the question is how much their authentication systems are built in a secured way. The authentication systems mostly depend on the user's general details such as name, photo, and location. In such systems, mischievous persons can easily create fake profiles by cloning the user’s identity to abuse the user’s information. Using fake profiles they can misuse original user’s photos, contacts, and videos. This kind of mischievous person can be identified by the use of privacy detection mechanisms. So, this research emphasizes some data mining techniques for protecting the original user’s information and to identify the malicious accounts in social network sites. By the assessment of 3PS (Publically Privacy Protection System), this work employs the malicious account detection method in OSN depending upon the mischievous person’s uncountable shared posts in a day and latest activity and behaviors. Examining the network similarity and comparison of attributes threshold values referred to the original user’s profile can be used to identify the malicious accounts. For this E_SVM-NN classifier is used based on the feature reduction techniques. This work involves in creating OSN accounts for experiments and investigates the latest updates, posts, comments, photos, and performing online search etc. which are used to evaluate the effectiveness and significance of the proposed work in contrast to the previous works.
Mucormycosis also termed as phycomycosis or zygomycosis is less commonly seen in oral cavity. However, it is an invasive, life-threatening and aggressive fungal infection. It mostly targets ...individuals with altered immunological system and diabetes. In this recent pandemic situation, the individuals affected with coronavirus disease 2019 (COVID-19) are also affected with this fungal infection which commonly involves the maxilla. In this case report, we present a case of a 45-year-old female affected with mucormycosis in post-COVID scenario involving mandible which is quite rare situation. The case report covers clinical findings, radiographic investigations and histopathological details with brief on literature review. Since mucormycosis is aggressive fungal infection, it should be handled with multimodal approach to reduce the systemic damage of an individual, morbidity and mortality.
Understanding ice accretion and aerodynamic performance degradation is essential in any aircraft certification program to ensure safe flight in icing conditions. In addition to well-known ...meteorological icing parameters and flight conditions, several physical and modeling parameters are known to play a critical role in the simulation of ice accretion on aircraft surfaces. In this study, the sensitivity of eight ice shape attributes and ice mass to five critical physical and modeling parameters was investigated using a high-fidelity computational method. In the sensitivity analysis, the Sobol sequence sampling method, the radial basis function, and Sobol's method were used to generate the sampling points in the given design space, to construct the metamodel, and evaluate the sensitivity indices, respectively. Based on the sensitivity indices, the number of shots turned out to be the largest contributor in the sum of both the first-order and total effects. Surface roughness was also shown to be the dominant parameter affecting the ice horn height and ice horn position because of the strong connection between roughness and heat flux. In general, it was shown that to varying degrees each parameter has a direct effect on ice accretion attributes and aerodynamic performance degradation. Further, it was noted that the parameters' interactions have a significant effect on the ice accretion attributes.
Elicitation of antibody and cell-mediated immune responses are crucial for successful vaccine development against tuberculosis (TB).
Mycobacterium tuberculosis
(Mtb) antigens CFP10 and ESAT6, potent ...and proven vaccine candidates require appropriate adjuvants to trigger better immune response. Virus-like particles carrying repetitive copies of foreign antigens can induce both T and B cell-mediated immunity required for conferring protection against intracellular pathogens. In this study, we developed hybrid potyvirus-like particles (PVLPs) displaying mycobacterial antigens on their surface by translationally fusing the coat protein (CP) gene derived from Johnson grass mosaic virus with CFP 10 or/and ESAT 6 gene(s). The recombinant plasmids carrying fusion constructs were transformed into

, the fusion proteins, viz. ESAT6-CP, CP-CFP10 and ESAT6-CP-CFP10, were expressed and purified using Ni-NTA

affinity chromatography under denaturing conditions. The chimeric CP fusion proteins were self-assembled in vitro into PVLPs by the gradual removal of denaturing conditions. The purified hybrid PVLPs carrying Mtb antigens when injected into mice showed enhanced immunogenicity for both ESAT6 and CFP10 antigens compared to the same antigens immunized without any adjuvant. In vitro stimulation of splenocytes derived from mice immunized with chimeric PVLPs upregulates the expression of cytokines involved in TB immune response.
Purpose
This paper aims to investigate the customers’ response to mandatory activities as per the corporate social responsibility (CSR) laws of India in the Indian hotel industry. Further, it ...analyzes the influence of mandatory CSR activities of the companies on the purchase intention (PI) of customers with the mediating role of customer satisfaction (CS). It also examines the link between mandatory CSR activities and the customers’ evaluation of corporate.
Design/methodology/approach

Findings
The study proves three propositions, namely, the mandatory CSR activities influence the PIs of customers, the CS partially mediates the relationship of CSR activities on the PI of the customers and the mandatory CSR activities demonstrate a positive impact on customers’ evaluation of corporate in the Indian hotel industry.
Originality/value
The comprehensive CSR assessment based on hotel customers’ response by considering CSR law in India is a novel outlook. The study will aid in determining the association between mandatory CSR and PI and evaluate the role of mandatory CSR on favorable corporate evaluation.
Accurately predicting de-icing processes is essential to ensure the proper sizing and design of ice protection systems in aircraft icing. A unified framework was developed to simulate an unsteady ...electrothermal de-icing process, using an unsteady formulation to account for phase change and runback water. Two physically-motivated concepts were newly introduced to the icing model to accurately describe the unsteady electrothermal de-icing (ice accretion/melting) process. A conjugate heat transfer method was utilized to tightly couple the ice and conduction solvers. Sub-iterations were incorporated at every time step to ensure the convergence of temperature and heat flux at the interface. The unsteady de-icing framework consists of a compressible Navier-Stokes-Fourier airflow solver, Eulerian droplet impingement solver, unsteady ice accretion/melting solver, and heat conduction solver, which can handle multilayer composite materials. All solvers were formulated based on partial differential equations and developed in a unified finite volume framework, enabling the use of a single grid system and eliminating unnecessary grid generation for the ice layer. The results showed better agreement with experimental data compared to other results. The unified solver was used to analyze the unsteady electrothermal de-icing process by investigating the ice accretion, ice melting, runback water film, and freezing of water film in unprotected areas. Runback water film due to ice melting may exceed the impingement limits and freeze in unprotected areas, leading to ice ridge formation.
