The purpose of this paper is to study the damage induced in “green” and synthetic composites under impact loading.

The study was focussed on epoxy-based composites reinforced with woven hemp or glass fibres. Six assessment techniques were employed in order to analyse and compare impact damages: eye observation, back face relief, terahertz spectroscopy, laser vibrometry, x-ray micro-tomography and microscopic observations.

Different damage detection thresholds for each material and technique were obtained. Damage induced by mechanical and laser impacts showed relevant differences, but the damage mechanisms are similar in both types of impact: matrix cracks, fibre failure, debonding at the fibres/matrix interface and delamination. Damage shape on back surfaces is similar after mechanical or laser impacts, but differences were detected inside samples.

The combination of these six diagnoses provides complementary information on the damage induced by mechanical or laser impacts in the studied green and synthetic composites.

The purpose of the present paper is to quantify and analyze the strain-rate dependence of the yield stress for both unfilled acrylonitrile-butadiene-styrene (ABS) and short carbon fiber-reinforced ABS (CF-ABS) materials, fabricated via material extrusion additive manufacturing (ME-AM). Two distinct and opposite infill orientation angles were used to attain anisotropy effects.

Tensile test samples were printed with two different infill orientation angles. Uniaxial tensile tests were performed at five different constant linear strain rates. Apparent densities were measured to compensate for the voided structure. Scanning electron microscope fractography images were analyzed. An Eyring-type flow rule was evaluated for predicting the strain-rate-dependent yield stress.

Anisotropy was detected not only for the yield stresses but also for its strain-rate dependence. The short carbon fiber-filled material exhibited higher anisotropy than neat ABS material using the same ME-AM processing parameters. It seems that fiber and molecular orientation influence the strain-rate dependence. The Eyring-type flow rule can adequately describe the yield kinetics of ME-AM components, showing thermorheologically simple behavior.

A polymer’s viscoelastic behavior is paramount to be able to predict a component’s ultimate failure behavior. The results in this manuscript are important initial findings that can help to further develop predictive numerical tools for ME-AM technology. This is especially relevant because of the inherent anisotropy that ME-AM polymer components show. Furthermore, short carbon fiber-filled ABS enhanced anisotropy effects during ME-AM, which have not been measured previously.

This study aims to develop a systematic literature review of customer value co-creation in the hospitality and tourism industry and present the different views of the scientific community, highlighting the dimensions, antecedents and outcomes of customer value co-creation.

This study adopted a systematic review process guided by the preferred reporting items for systematic reviews and meta-analyses protocol. Data were collected through a search for papers in Scopus, EBSCO, Web of Science and Science Direct databases. The systematic review was performed based on 216 validated articles.

The study reveals that the manifestations of customer value co-creation can be understood, based on two fundamental dimensions: customer behaviours and factors that shape co-creation. However, some antecedents are closely linked to the customer, social environment, service provider and technological resources. Moreover, there are numerous outcomes resulting from customer value co-creation, grouped in customer results, perceived value and organizational performance and market outcomes.

This research contributes to a more informed explanation for hospitality and tourism organizations about the importance of tourist and guest involvement in value co-creation. This systematic knowledge can facilitate the design of the service, as well as the value proposition offered by hospitality and tourism organizations.

The study extends the literature by systematizing the empirical and conceptual knowledge, using for the first time a systematic literature review.

In Brazil, the city of Pelotas experienced an economic apex between the end of the nineteenth century and the beginning of the twentieth century, reflecting in the construction of several buildings. The aim of this article is to evaluate the state of degradation of the facades of the Old School of Agronomy Eliseu Maciel, using qualitative and quantitative indicators.

The study was divided into visual and photographic survey, damage map and subsequent application of the Degradation Measurement Method (MMD) and the Element Performance Index (Ip). Taking into consideration the evaluation of the building: through historical research and survey of damages. Finally, the building was framed at a level of degradation.

By calculating the average damage between the methods – damage map, MMD and Ip – a more faithful representation of the damage was obtained, since the values become balanced. The results show the potential of the use of the methods in the analysis of pathological manifestations in facades.

The originality of this article refers to the use of methods for evaluation of historical buildings. The authors believe that the methods described applied jointly provide the results about the state of degradation through nondestructive and low-cost analyses. The methods of surveying damage to Brazilian heritage are a little researched area. This work will hopefully be engaged by academics and professionals to help establish and promote broad government interest and investments.

The purpose of this paper is to report on a study that was done among older adults in the city of Bahia Blanca, Argentina regarding their awareness and use of cultural heritage and commercial recreational sites.

This exploratory study among this historically understudied segment of the population used interviews and historical images to analyze their perceptions about such spaces and to establish a link between those perceptions and their civic identity.

The study found that appreciation of local cultural heritage sites was considerably lower than appreciation of commercial recreational areas and suggests possible interventions to enhance the use and appreciation of cultural heritage sites.

This paper about Bahia Blanca derives its relevance from venturing into an analysis of the opinions about such sites among an age segment, the elderly, that has been poorly addressed in other studies, in particular in the Latin American context. The study reported here generated firsthand information that may serve public servants in making decisions in the context of locally developed cultural policies and presents a methodological model and data collection and analysis techniques that may be of interest for development elsewhere.

In Argentina there is a lack of research studies in the “older adults” age bracket. The contribution of this manuscript lies in creating a connectivity among concepts such as recreation/leisure, heritage and lived space, by using new contributions in the geography of leisure that are associated with the geography of everyday life. The concepts are integrated in the study of subjective spaces of individuals.

The quality of tourist accommodation establishments is a recurring theme in public strategies for planning and managing tourist destinations. The applying standards as a way to achieve quality. This strategy consists of legally regulating a series of minimum physical standards by using measureable parameters, as well as the desired characteristics or levels of amenities, which vary according to the type of provision required. The purpose of this study is to analyze the strengths and weaknesses of applying strategies that regulate standards for accommodations in coastal tourism areas in the Canary Islands (Spain).

The authors used an explanatory case study methodology. An “inter-case” comparison has been chosen, because the object of analysis (public policy applying tourism standards) has changed over time; furthermore, a content analysis approach was selected so that the subject of this research is the process of implementing this kind tourism policy. The result is a systematization of the process in stages.

Quantifiable criteria that exclusively consider the physical or operational parameters of a tourist establishment are no longer sufficient to provide quality service that meets the needs and expectations of customers. It is not enough to set standards for surface area parameters or essential amenities when organizing new tourist developments, but rather it is the qualitative aspect that must be addressed. At the same time, quality tourist accommodation establishment is not obtained merely by reducing density, which constitutes the significant standard.

This paper evidence is presented that may influence the quality of accommodation perceived by the client, which increases their level of satisfaction and, in turn, the degree of trust and, therefore, fidelity, understood as the future decision to repeat or not the tourist experience. There are also issues related to the approach that the quality of accommodation establishments has a direct effect on the visitor’s perception of the destination, which cannot be merely physical, mensurable in square metres.

The relationship between urban standards and quality is no longer linear. This determines that the regulated tourist accommodations (defined by sectoral regulations) it is common to set a required plot size in m2 based on the number of bed places offered by the establishment is no longer valid. Today, tourists rate accommodation establishments by the prestige of their brand or the diversity of services and experiences (entertainment, sensations, emotions, etc.) they provide. These experiences play such an important role in producing customer satisfaction and loyalty to a hotel that guests are willing to pay more for their stay, with the understanding that they will be able to experience certain emotions. It has been evidenced that the main reason for setting physical quality parameters that can be measured by a rating system for accommodation establishments, to provide a basic reference for customers, is no longer necessary, given the amount of easily accessible real-time information freely available through multiple independent channels based on the 2.0 paradigm, information technologies and communication, as well as applications and virtual platforms.

Applying this public strategy of classifying or rating tourist accommodations on a territorial scale has some strengths and weaknesses. However, it is not easy to find a comprehensive evaluation of the impact of such strategies because, among other issues, the public administration seems disinterested in measuring the consequences of their decisions, instead focussing on whether the formal legal requirements are being complied with. Moreover, whenever such assessments have been carried out, the discussion has been limited to the effectiveness of the implementation. This is why, beyond such purely mechanical responses, there are currently no studies or technical reports that specifically examine the positive or negative effects of such approaches. Evidently, these circumstances make any work analyzing this material relevant and timely.

This study examines the impact of corporate social responsibility (CSR) on innovation, considering the role of the three dimensions of intellectual capital (human capital, structural capital and relational capital). Specifically, the analysis explores the direct effect of CSR and intellectual capital on innovation, the effect of CSR on intellectual capital, and the mediating effect of intellectual capital on the relationship between CSR and innovation.

Data were collected from a sample of 101 Tunisian firms operating in various industries. The conceptual model of direct and indirect effects was tested with partial least squares structural equation modelling (PLS-SEM) using SmartPLS 4 software.

CSR is positively related to innovation, as well as all dimensions of intellectual capital. Structural capital is the only dimension of intellectual capital that has a significant effect on innovation. CSR affects innovation through its impact on structural capital.

Most studies have examined the direct effect of CSR on innovation in firms in developed countries. In contrast, this research sheds light on the mediating role of intellectual capital in this relationship, underlining the specific role of human capital, relational capital and structural capital. In addition, the study focuses on a developing country, which thus differentiates it from previous studies.
