Polyethylene terephthalate (PET) as a fiber molding polymer is widely used in aerospace, electrical and electronic, clothing and other fields. The purpose of this study is to improve the thermal insulation performance of polyethylene terephthalate (PET), the SiO₂ aerogel/PET composites slices and fibers were prepared, and the effects of the SiO₂ aerogel on the morphology, structure, crystallization property and thermal conductivity of the SiO₂ aerogel/PET composites slices and their fibers were systematically investigated.

The mass ratio of purified terephthalic acid and ethylene glycol was selected as 1:1.5, which was premixed with Sb₂O₃ and the corresponding mass of SiO₂ aerogel, and SiO₂ aerogel/PET composites were prepared by direct esterification and in-situ polymerization. The SiO₂ aerogel/PET composite fibers were prepared by melt-spinning method.

The results showed that the SiO₂ aerogel was uniformly dispersed in the PET matrix. The thermal insulation coefficient of PET was significantly reduced by the addition of SiO₂ aerogel, and the thermal conductivity of the 1.0 Wt.% SiO₂ aerogel/PET composites was reduced by 75.74 mW/(m · K) compared to the pure PET. The thermal conductivity of the 0.8 Wt.% SiO₂ aerogel/PET composite fiber was reduced by 46.06% compared to the pure PET fiber. The crystallinity and flame-retardant coefficient of the SiO₂ aerogel/PET composite fibers showed an increasing trend with the addition of SiO₂ aerogel.

The SiO₂ aerogel/PET composite slices and their fibers have good thermal insulation properties and exhibit good potential for application in the field of thermal insulation, such as warm clothes. In today’s society where the energy crisis is becoming increasingly serious, improving the thermal insulation performance of PET to reduce energy loss will be of great significance to alleviate the energy crisis.

In this study, SiO₂ aerogel/PET composite slices and their fibers were prepared by an in situ polymerization process, which solved the problem of difficult dispersion of nanoparticles in the matrix and the thermal conductivity of PET significantly reduced.

The use of waste polyethylene terephthalate (PET) plastics derived from shredded bottles in concrete is not formalized yet, especially in reinforced members such as beams and columns. The disposal of plastic wastes in concrete is a viable alternative to manage those wastes while minimizing the environmental impacts associated to recycling, carbon dioxide emissions and energy consumption.

This paper evaluates the suitability of 2D deterministic and stochastic finite element (FE) modeling to predict the shear strength behavior of reinforced concrete (RC) beams without stirrups. Different concrete mixtures prepared with 1.5%–4.5% PET additions, by volume, are investigated.

Test results showed that the deterministic and stochastic FE approaches are accurate to assess the maximum load of RC beams at failure and corresponding midspan deflection. However, the crack patterns observed experimentally during the different stages of loading can only be reproduced using the stochastic FE approach. This later method accounts for the concrete heterogeneity due to PET additions, allowing a statistical simulation of the effect of mechanical properties (i.e. compressive strength, tensile strength and Young’s modulus) on the output FE parameters.

Data presented in this paper can be of interest to civil and structural engineers, aiming to predict the failure mechanisms of RC beams containing plastic wastes, while minimizing the experimental time and resources needed to estimate the variability effect of concrete properties on the performance of such structures.

This study aims to deal with both the development and mechanical investigations of unsaturated polyester matrix (UPR) composites containing recycled polyethylene terephthalate (PET) fibers as new fillers.

UPR/PET fibers composites have been developed as mats by incorporating 5, 8, 13 and 18 parts per hundred of rubber (phr) of 6-, 10- and 15-mm length PET fibers from the recycling of postconsumer bottles. The mechanical and physical properties of the composites were investigated as a function of fiber content and length. A significant increase in stress at break and in ultimate stress (sr) were observed for composites reinforced with 5 and 8 phr of 15-mm length PET fibers. The Izod impact strength of UPR/mat PET fiber composites as a function of fiber rate and length showed that the 5 and 8 phr composites for the 15-mm length PET fiber have the optimal mechanical properties 13.55 and 10.50 Kj/m², respectively. The morphological study showed that the strong adhesion resulting from the affinity of the PET fiber for the UPR matrix. The ductile fracture of materials reinforced with 5 and 8 phr is confirmed by the fiber deformation and fracture surface roughness.

This study concluded that the PET fiber enhances the properties of composites, a good correlation was observed between the results of the mechanical tests and the structural analysis revealing that for the lower concentrations, the PET fibers are well dispersed into the resin, but entanglements are evidenced when the fiber content increases.

It can be shown from scanning electron microscopy micrographs that the fabrication technique produced composites with good interfacial adhesion between PET fibers and UPR matrix.

Pet-friendly hotels are growing rapidly. The prevalence of pet adoption has largely resulted from the loneliness due to social distancing that happened during the Coronavirus disease 2019 pandemic. Many hotels around the world aim to become pet-friendly to satisfy the growing demand. Hoteliers believe that the popularity of pet-friendly hotels will continue, as pet owners often treat pets as their kids. This study aims to investigate how pet-friendly hotels need to design and manage pet-friendly services and policies.

Using grounded theory methodology, this research conducts interviews with 25 pet-friendly hotel managers from Hong Kong (HK). The study includes hotels from different hotel categories and classifications. It examines the conceptualization of pet-friendly service design, drawing on a service blueprint.

Building on the service marketing and service blueprint literature, this research provides a synthesis that reflects how pet-friendly hotels can serve both guests with and without pets. The findings reveal that pet-owner’s service expectations are formed on anthropomorphism, that is, an inclination of attributing human features to nonhuman entity. Hotel managers, and particular those who have pets personally understand better how pet-friendly service can be adapted to meet the expectations and requirements of pet owners while accommodating guests without pets. The market of pet-friendly hospitality is growing, with high profit potential from pet owners who are willing to spend generously.

Data were collected from selected pet-friendly hotels in HK through interviews with pet-friendly service providers. The research is qualitative and exploratory in nature. It aims to explore and examine the multilevel pet-friendly hospitality service design from a managerial perspective. This research enriches the literature on anthropomorphism theory, the design of pet-friendly services and the application of service blueprint.

The research offers explicit suggestions for the design of pet-friendly hospitality services. A pet-friendly hotel service blueprint is developed. This can help managers to develop essential pet-friendly policies and service collaborations between internal departments and with external specialist organizations, maximizing the value for all stakeholders.

The study explores a rapidly emerging market and scrutinizes its specific design requirements. It extends theoretical insights by enriching the anthropomorphism theory and broadening the conceptualizations of service blueprint based on anthropomorphism theory.

Social exclusion is a complicated psychological phenomenon with behavioral ramifications that influences consumers' lifestyles and behaviors. In contrast, anthropomorphism is a phenomenon that marketing strategists employ and that occurs in customers' lives as a result of social isolation. The literature discusses these two complicated structures as ones that require investigation based on consumer judgments. The purpose of the current study is to understand the fundamental motivations that underlie the propensity for anthropomorphizing in people who suffer social isolation through their pets.

To look into the motivations driving these themes, a study technique with three distinct components was created. Cyberball was employed as a technique to manipulate social exclusion in the initial stage of this research methodology. Two scenarios, one of which had an anthropomorphizing tendency and the other of which did not, were presented to participants who had suffered social exclusion and advanced to the second phase in order to determine the anthropomorphizing tendency. The Attachment to Pets Scale (LAPS), which Johnson et al. (1992) created based on the social support provided by pets, was utilized while creating the scenarios. The Zaltman method was applied as an interviewing technique in the third stage of the research design, with the interviewees being guided by visuals that reflected their emotions and thoughts.

The results of the data analysis were evaluated in light of social psychology. A more thorough expression of the complex relationship between anthropomorphism and those who experience social exclusion has been made. The findings showed that when people anthropomorphize their pets in response to feelings of social exclusion, the motivations that emerge include pure love, loyalty, animals' need for a human, living creature and embracing. The study emphasizes that these ideas will be helpful in customers' interactions with anthropomorphic objects.

As a contribution to the literature, the study findings offer the five major motivations underpinning these beliefs. These findings may help marketing scientists comprehend social exclusion and anthropomorphism, thereby benefiting the individual and society.

The majority of research in the literature (Chen et al., 2017; Epley et al., 2008; Eyssel and Reich, 2013; Waytz et al., 2019) verified that people who were socially excluded would use anthropomorphism, but no studies were discovered about the motivations outlined in the current study. The results of this investigation should add to the body of knowledge in this area. The pet was employed as an anthropomorphism tool in the current study because it is the object that a person chooses to anthropomorphize deliberately and independently. It adds to the study's originality by explaining in the individual's own terminology how he will feel as a result of his social isolation, how he will make up for it and potential responses he may have. In addition to all of these contributions, the study's primary goal of analyzing the motivations behind anthropomorphism yields significant findings that are relevant to both industry and academic research.

This paper aims to assess retail shopping avenues for young consumers based on the type of guidance and assistance they pursue (social media vs professional service provider) in purchasing situations judged to be important. Young consumers consider themselves pet parents and pets represent an extension of self. Thus, pet-related products, by their importance, represent an excellent area of analysis for this inquiry.

Data collection was completed in a way that is contextually relevant and gives the results ecological validity with the assistance of a major supplier of pet food. A total of 470 Gen Z owners of small companion animals were obtained. The partial least squares structural equation modeling testing method is considered appropriate for the model analysis due to the structure and homogeneity of the sample and due to the precision of the method.

Results indicate that, in accordance with social media engagement (SME) theory, high SME elevated social commerce purchase intentions while professional advice seekers reported increased brick-and-mortar shopping. Thus, context-dependent, young consumers may purchase from brick-and-mortar sites.

This paper draws on SME and Advice Response Theory and proposes an original model explaining channel selection preferences for young consumers based on the type of advice sought for important purchasing decisions. The model represents a steppingstone to investigate the mechanism that translates information search sources into buying through different channels.

This study aims to prepare an imprinted composite membrane with grafted temperature-sensitive blocks for the efficient adsorption and separation of rhenium(Re) from aqueous solutions.

PVDF resin membrane was used as the substrate, dopamine and chitosan (CS) were used to modify the membrane surface and temperature-sensitive block PDEA was grafted on the membrane surface. Then acrylic acid (AA) and N-methylol acrylamide (N-MAM) were used as the functional monomers, ethyleneglycol dimethacrylate (EGDMA) as the cross-linker and ascorbic acid-hydrogen peroxide (Vc-H₂O₂) as the initiator to obtain the temperature-sensitive ReO4⁻ imprinted composite membranes.

The effect of the preparation process on the performance of CS–Re–TIICM was investigated in detail, and the optimal preparation conditions were as follows: the molar ratios of AA–NH₄ReO₄, N-MAM and EGDMA were 0.13, 0.60 and 1.00, respectively. The optimal temperature and time of the reaction were 40 °C and 24 h. The maximum adsorption capacity of CS–Re–TIICM prepared under optimal conditions was 0.1071 mmol/g, and the separation was 3.90 when MnO4⁻ was used as the interfering ion. The quasi first-order kinetics model and Langmuir model were more suitable to describe the adsorption process.

With the increasing demand for Re, the recovery of Re from Re-containing secondary resources becomes important. This study demonstrated a new material that could be separated and recovered Re in a complex environment, which could effectively alleviate the conflict between the supply and demand of Re.

This contribution provided a new material for the selective separation and purification of ReO4⁻, and the adsorption capacity and separation of CS–Re–TIICM were increased with 1.673 times and 1.219 time compared with other Re adsorbents, respectively. In addition, when it was used for the purification of NH₄ReO₄ crude, the purity was increased from 91.950% to 99.999%.

Whilst a growing body of support exists for the use of prison animal programmes (PAPs), research within UK prisons is sparse. Opportunity to add to this body of literature is also limited due to the practical barriers around safely embedding animals within forensic settings. This study aims to capitalise on an opportunity to explore a visitation model of a prison-based dog programme (PBDP), recently implemented within a UK prison. The intervention requires staff members to volunteer to bring their pets into the prison on a weekly basis and to accompany them as they complete their normal day-to-day prison roles.

Data was collected within a Category B adult prison for males convicted of a sexual offence. Semi-structured interviews were carried out with six prisoners who had spent time with the visitation dogs and six staff members who had been part of those interactions. Reflexive thematic analysis was used to analyse the data, and three themes were developed that focused specifically on the value of this model of PBDP (staff members bringing their pets into the prison).

Three themes (reconnecting men to their outside lives; legitimising pro-social narrative; and “a safe space for them to open up”) were developed from participants’ lived experience of the intervention and its perceived value.

The potential for a low-level PAP to contribute to a rehabilitative prison culture was supported.

To the best of the author’s knowledge, this is the first study to explore the value of this particular model of PBDP within a UK prison.

Because of the anisotropy of the process and the variability in the quality of printed parts, finite element analysis is not directly applicable to recycled materials manufactured using fused filament fabrication. The purpose of this study is to investigate the numerical-experimental mechanical behavior modeling of the recycled polymer, that is, recyclable polyethylene terephthalate (rPET), manufactured by a deposition FFF process under compressive stresses for new sustainable designs.

In all, 42 test specimens were manufactured and analyzed according to the ASTM D695-15 standards. Eight numerical analyzes were performed on a real design manufactured with rPET using Young's compression modulus from the experimental tests. Finally, eight additional experimental tests under uniaxial compression loads were performed on the real sustainable design for validating its mechanical behavior versus computational numerical tests.

As a result of the experimental tests, rPET behaves linearly until it reaches the elastic limit, along each manufacturing axis. The results of this study confirmed the design's structural safety by the load scenario and operating boundary conditions. Experimental and numerical results show a difference of 0.001–0.024 mm, allowing for the rPET to be configured as isotropic in numerical simulation software without having to modify its material modeling equations.

The results obtained are of great help to industry, designers and researchers because they validate the use of recycled rPET for the ecological production of real-sustainable products using MEX technology under compressive stress and its configuration for numerical simulations. Major design companies are now using recycled plastic materials in their high-end designs.

Validation results have been presented on test specimens and real items, comparing experimental material configuration values with numerical results. Specifically, to the best of the authors’ knowledge, no industrial or scientific work has been conducted with rPET subjected to uniaxial compression loads for characterizing experimentally and numerically the material using these results for validating a real case of a sustainable industrial product.

Understanding how firms manage multiple stakeholders is an academic and business call. This paper aims to describe a firm’s processes to implement a stakeholder value creation system, defined as the firm’s processes to create appropriate value with multiple stakeholders.

The authors based their investigation on a conceptual framework extracted from a previous literature review. From there, the authors conducted qualitative empirical research designed as a multiple-case study. In-depth interviews with 47 people from 11 different firms are the key source of this study.

This paper proposes a framework demonstrating how a firm can implement a stakeholder value creation system. Results pointed to three processes: value creation, distribution and capture. Value distribution mechanisms are drivers for both value creation and capture processes. The system is a set of multiple flow relationships between the firm and its stakeholders.

This research is limited to the Brazilian context.

The stakeholder value creation system is composed of seven elements: walk-the-talk organizational behavior, stakeholder business model, societal non-attended need, stakeholder preference matrix, stakeholder bargaining power, retention of rents and governance mechanism. Managers may design their firm’s unique processes using these elements as drivers.

The present investigation demonstrates that societal issues matter for firms to formulate strategies that positively impact their economic, social and environmental results.

The authors investigated competitive strategy concepts of value creation and appropriation from a combination of resource-based and stakeholder theories and a system perspective. The framework of this study consolidated both theories’ ideas from a complementary perspective. The authors suggest managers and academics should adopt the power of the “AND” position instead of the “OR” trade-off position.
