The paper seeks to bridge the already familiar benefits of 3D printing (3DP) to the rehabilitation of cultural heritage, still based on the use of complex and expensive handcrafted techniques and scarce materials.

A compilation of different information on frequent anomalies in cultural heritage buildings and commonly used materials is conducted; subsequently, some innovative techniques used in the construction sector (3DP and 3D scanning) are addressed, as well as some case studies related to the rehabilitation of cultural heritage building elements, leading to a reflection on the opportunities and challenges of this application within these types of buildings.

The compilation of information summarised in the paper provided a clear reflection on the great potential of 3DP for cultural heritage rehabilitation, requiring the development of new mixtures (lime mortars, for example) compatible with the existing surface and, eventually, incorporating some residues that may improve interesting properties; the design of different extruders, compatible with the new mixtures developed and the articulation of 3D printers with the available mapping tools (photogrammetry and laser scanning) to reproduce the component as accurately as possible.

This paper sets the path for a new application of 3DP in construction, namely in the field of cultural heritage rehabilitation, by identifying some key opportunities, challenges and for designing the process flow associated with the different technologies involved.

This paper presents a comparative analysis of artwork produced in the context of social movements waged by Mexicans and Chicanos (U.S. inhabitants of Mexican descent) during the two decades between the mid-1960s and the mid-1980s. Despite the fact that activists in these movements shared many elements of Mexican culture and history, were part of the same generation of radical social movements born in the 1960s, and experienced some significant interchange among movement participants from each side of the U.S.-Mexico border, an examination of movement art reveals significant differences in key elements of the movements’ collective identity and expression of political citizenship. Analysis of the artwork also highlights different aesthetic choices made by movement artists, particularly with regard to the deployment of formal elements associated with the “Mexican School” of art made famous by artists associated with the Mexican Revolution of the early 20th century. Variations in the representational strategies developed by movement artists reflect the distinct relationship of movement constituents in Mexico and the U.S. to each nation's prevailing regimes of accumulation and modes of regulation. The analysis is based on an examination of 374 pieces of art.

This chapter explores the work of Stephen Bunker through a review of the role of women in Amazonian extractive economies and how shifting ideas of development affected them in the Western Amazon. While the initial development programs for Extractive Reserves focused on green marketing, consumer coops and value added through processing carried out in an urban factory in the village of Xapuri, as structural adjustment programs gained importance, the development emphasis shifted to decentralized processing and piecemeal contracts on the individual seringal (rubber tapping estate) or in mini factories in forests. While this was an appealing approach given the kinds of development concerns at the time; non-timber forest products, income generation for women in the forest itself, and neoliberal ideologies of economic and labor decentralization, it failed to appreciate the demands and the opportunity costs on women's time in rural areas and underestimated the importance of formal employment in urban areas. The logics on which the shift was justified, enhanced production, efficiency and lower costs, did not materialize.

The manufacturing of intelligent and secure visual data transmission over the wireless sensor network is key requirement nowadays to many applications. The two-way transmission of image under a wireless channel needed image must compatible along channel characteristics such as band width, energy-efficient, time consumption and security because the image adopts big space under the device of storage and need a long time that easily undergoes cipher attacks. Moreover, Quizzical the problem for the additional time under compression results that, the secondary process of the compression followed through the acquisition consumes more time.

Hence, for resolving these issues, compressive sensing (CS) has emerged, which compressed the image at the time of sensing emerges as a speedy manner that reduces the time consumption and saves bandwidth utilization but fails under secured transmission. Several kinds of research paved path to resolve the security problems under CS through providing security such as the secondary process.

Thus, concerning the above issues, this paper proposed the Corvus corone module two-way image transmission that provides energy efficiency along CS model, secured transmission through a matrix of security under CS such as inbuilt method, which was named as compressed secured matrix and faultless reconstruction along that of eminent random matrix counting under CS.

Experimental outputs shows intelligent module gives energy efficient, secured transmission along lower computational timing also decreased bit error rate.

The transition to omnichannel retail is the recognized future of retail, which uses digital technologies (e.g. augmented reality shopping assistants) to enhance the customer shopping experience. However, retailers struggle with the implementation of such technologies in brick-and-mortar stores. Against this background, the present study investigates the impact of a smartphone-based augmented reality shopping assistant application, which uses personalized recommendations and explainable artificial intelligence features on customer shopping experiences.

The authors follow a design science research approach to develop a shopping assistant application artifact, evaluated by means of an online experiment (n = 252), providing both qualitative and quantitative data.

Results indicate a positive impact of the augmented reality shopping assistant application on customers' perception of brick-and-mortar shopping experiences. Based on the empirical insights this study also identifies possible improvements of the artifact.

This study's assessment is limited to an online evaluation approach. Therefore, future studies should test actual usage of the technology in brick-and-mortar stores. Contrary to the suggestions of established theories (i.e. technology acceptance model, uses and gratification theory), this study shows that an increase of shopping experience does not always convert into an increase in the intention to purchase or to visit a brick-and-mortar store. Additionally, this study provides novel design principles and ideas for crafting augmented reality shopping assistant applications that can be used by future researchers to create advanced versions of such applications.

This paper demonstrates that a shopping assistant artifact provides a good opportunity to enhance users' shopping experience on their path-to-purchase, as it can support customers by providing rich information (e.g. explainable recommendations) for decision-making along the customer shopping journey.

This paper shows that smartphone-based augmented reality shopping assistant applications have the potential to increase the competitive power of brick-and-mortar retailers.
