An outbreak of a bacterial contagion is a critical threat for human health worldwide. Recently, light-activated heterostructured nanomaterials (LAHNs) have shown potential as antibacterial agents, owing to their unique structural and optical properties. Many investigations have revealed that heterostructured nanomaterials are potential antibacterial agents under light irradiation. In this review, we summarize recent developments of light-activated antibacterial agents using heterostructured nanomaterials and specifically categorized those agents based on their various light harvesters. The detailed antibacterial mechanisms are also addressed. With the achievements of LAHNs as antibacterial agents, we further discuss the challenges and opportunities for their future clinical applications.

Sustainable manufacturing requires simultaneous consideration of economic, environmental, and social implications associated with the production and delivery of goods. Fundamentally, sustainable manufacturing relies on descriptive metrics, advanced decision-making, and public policy for implementation, evaluation, and feedback. In this paper, recent research into concepts, methods, and tools for sustainable manufacturing is explored. At the manufacturing process level, engineering research has addressed issues related to planning, development, analysis, and improvement of processes. At a manufacturing systems level, engineering research has addressed challenges relating to facility operation, production planning and scheduling, and supply chain design. Though economically vital, manufacturing processes and systems have retained the negative image of being inefficient, polluting, and dangerous. Industrial and academic researchers are re-imagining manufacturing as a source of innovation to meet society's future needs by undertaking strategic activities focused on sustainable processes and systems. Despite recent developments in decision making and process- and systems-level research, many challenges and opportunities remain. Several of these challenges relevant to manufacturing process and system research, development, implementation, and education are highlighted.

This article puts forward the fundamental lines of thought on the Political Economy of Communications and the Media, since the development of capitalism up to the present day. Clarifying the distinction between Economy and Political Economy, this work examines the central split between two traditions within Political Economy: the Classic approach which is centred on markets and competition mechanisms and the Critical approach which is centred on the analysis of property and the distribution of power in society. Despite internal distinct traditions, for political economists’ questions about cultural production and consumption are never simply matters of economic organisation or creative expression and the relations between them. They are always also questions about the organisation of power and its consequences for the constitution of public life. Based on different Political Economy perspectives, this article attempts to present the most recent developments on communications and media markets in Europe and the major challenges and opportunities the discipline faces in a time marked by the emergence of a digital public sphere.

This chapter summarizes the physical properties of THz antennas, provides a summary of some of the most important recent developments in the field of energy harvesting of Earth long-wave infrared radiation, discusses the potential applications and identifies the future challenges and opportunities. In particular, a THz antenna is designed in order to transform the thermal energy, provided by the Sun and re-emitted from the Earth, in electricity. The proposed antenna is a square spiral of gold printed on a low cost dielectric substrate. Simulations have been conducted in order to investigate the behavior of the antenna illuminated by a circularly polarized plane wave with an amplitude chosen according to the Stefan-Boltzmann radiation law. Moreover, these THz antennas could be coupled with other components to obtain direct rectification of T radiation. As a consequence, these structures further optimized could be a promising alternative to the conventional photovoltaic solar cells.

Globally increasing numbers of older people bring both challenges and opportunities for old age psychiatry services. This chapter outlines the history, underlying principles, and policy context for contemporary mental health services for older people. It discusses components of services, including community health teams, memory assessment services, consultation-liaison psychiatry, and in-patient mental health care, as well as newer types of service, such as crisis teams and outreach to care homes. Other recent developments include various models of case management and emphasis on post-diagnostic support. Equally important are issues of equality and access, and the chapter covers several key areas, such as age, gender, sexual orientation, religion and spirituality, and rurality. Major challenges to old age psychiatry come from limited resources and non-recognition of the distinct needs of older adults, as well as the demands of the growing older population, advances in science and technology, and the need to attract talented psychiatrists into this field.

This chapter introduces digital rights management (DRM) in the perspective of digital policy management (DPM) focusing on the enterprise and corporate sector. DRM has become a domain in full expansion with many stakes which are by far not only technological. They also touch legal aspects as well as business and economic. Information is a strategic resource and as such requires a responsible approach of its management, almost to the extent of being patrimonial. Digital rights and policy management is now well established mainly in two distinct sectors sharing the same fundamental underlying technical principles: on the one hand, the entertainment and media industry, and on the other hand, the enterprise sector. This chapter mainly focuses on the latter, introducing DRM concepts, standards, and the underlying technologies from its origins to its most recent developments in order to assess the challenges and opportunities of enterprise digital policy management.

This study examines recent developments in destination assessment and certification as a basis for identifying challenges and benefits they engender, from tourist and tourism organizations’ perspectives. It uses online surveys and semi-structured interviews to collect primary data from prospective tourists and key informants on destination assessment and certification. The findings highlight the strengths and weaknesses of schemes currently in use, including various factors that might influence their future development. Specifically, the study finds that destination assessment and certification are affected by four key issues, namely, practicability, reliability, visibility, and (un)availability of incentives. It concludes that the manifestation of these issues and their ensuing complexity affect the way in which tourists and tourism destinations engage with destination assessment and certification. This, therefore, delimits the inherent opportunities and constraints within such schemes.

Bioactive compounds are a large group of compounds (antimicrobials, antioxidants, nutrients, etc.), but its use in edible films and coatings for application on fruits and vegetables has been very important because nowadays the consumers demand fruits and vegetables that are fresh, healthy, high quality and easy to prepare. A number of investigations have shown that the use of additives in edible films and coatings improve its functionability and provide compounds for human health. However, it is necessary to continue research that can generate specific or tailor-made edible films and coatings for each product with the best characteristics for preservation. In this review we present and analyze the concepts, progress and perspectives in the design and application of edible films and coatings for fruits and vegetables in order to define the challenges and opportunities that this topic of study in the field of science, technology and food engineering.
