Abstract Advanced wastewater treatment is often used to produce one single water quality. In recent years, technologies have been developed that allow the production of different qualities that are fit for their purpose. These technology bundles are still not being marketed, and market requirements are unclear. Two constellations in West Basin, California and in Oman were analysed to shed light on the different constellations of actors, resource situations and institutions. The first led to the industrial reuse of several water qualities, while the second produced an application in holiday resorts, leisure and food production. A hypothetical solution was contrasted with an historical case. The analysis of the constellations showed that multi-sectoral investments and dependencies require strong cooperation arrangements and long-term agreements. Governmental institutions were revealed to be suitable for coordinating the process, especially during the initial phase, but also in view of security of supply. A (comparative) examination allows an initial, still provisional systematic overview of other constellations that favour systems with recycled water of different qualities. Further research is required to understand the welfare and distribution effects of multimodal water pricing policies and the feasibility of co-financing of agricultural irrigation and opportunities for more sustainable water reuse.

This paper studies how receiving a bonus changes the consumers’ demand for auto loans and the risk of future delinquency. Unlike traditional consumer products, auto loans have a long-term impact on consumers’ financial state because of the monthly payment obligation. Using a large consumer panel data set of credit and employment information, the authors find that receiving a bonus increases auto loan demand by 21 percent. These loans, however, are associated with higher risk, as the delinquency rate increases by 18.5 −31.4 percent depending on different measures. In contrast, an increase in consumers’ base salary will increase the demand for auto loans but not the delinquency. By comparing consumers with bonuses with those without bonuses, the authors find that bonus payments lead to both demand expansion and demand shifting on auto loans. The empirical findings help shed light on how consumers make financial decisions and have important implications for financial institutions on when demand for auto loans and the associated risk arise.

Insight Into

Purpose The purpose of this paper is to provide an insight into how the demographic of international and home students in the major university cities in three European countries (France, Spain and Germany) offers investors an opportunity to provide students housing. This paper looks at how a mobile and demanding student clientele now demands, well priced, good quality and purpose built accommodation during their studies at University. This offers a good property investment opportunity. Design/methodology/approach This practice briefing is an overview of the demand factors that are creating opportunities in France, Spain and Germany. Findings This paper analyses the link between the under provision of purpose built student housing and an opportunity to develop a long-term cash flow producing investment asset. Practical implications The role of the property developers and investors is to successfully identify trends and demands and provide the assets that meet the market requirements. This paper looks at the meeting point in three major European countries for this latent and, currently, poorly served demand. Originality/value This provides guidance on how investment opportunities develop in non-traditional property markets.

Image Caption

Personalized image caption, a natural extension of the standard image caption task, requires to generate brief image descriptions tailored for users' writing style and traits, and is more practical to meet users' real demands. Only a few recent studies shed light on this crucial task and learn static user representations to capture their long-term literal-preference. However, it is insufficient to achieve satisfactory performance due to the intrinsic existence of not only long-term user literal-preference, but also short-term literal-preference which is associated with users' recent states. To bridge this gap, we develop a novel multimodal hierarchical transformer network (MHTN) for personalized image caption in this paper. It learns short-term user literal-preference based on users' recent captions through a short-term user encoder at the low level. And at the high level, the multimodal encoder integrates target image representations with short-term literal-preference, as well as long-term literal-preference learned from user IDs. These two encoders enjoy the advantages of the powerful transformer networks. Extensive experiments on two real datasets show the effectiveness of considering two types of user literal-preference simultaneously and better performance over the state-of-the-art models.

Abstract Our intent is to reinterpret the concept of middle-income trap using the language of the complex system approach to refer to the unpredictability, non-linearity and the enormous range of possible behaviors of economic development in the long-term time series. By redefining the concept of trap in those terms, we propose to shed light on the institutional background of economic development. In order to advance our argument, we conduct a case study of Latin America, a region that has presented an unstable and non-linear economic trajectory across the 20th century. We argue that the combination between the colonial economic legacy and the political fragmentation amid the process of independence shaped the socio-economic structure and institutional capabilities for years to come, restricting the possibilities of overcoming underdevelopment.

AbstractCOVID-19-related controversies concerning the allocation of scarce resources, travel restrictions, and physical distancing norms each raise a foundational question: How should authority, and thus responsibility, over healthcare and public health law and policy be allocated? Each controversy raises principles that support claims by traditional wielders of authority in “federal” countries, like federal and state governments, and less traditional entities, like cities and sub-state nations. No existing principle divides “healthcare and public law and policy” into units that can be allocated in intuitively compelling ways. This leads to puzzles concerning (a) the principles for justifiably allocating “powers” in these domains and (b) whether and how they change during “emergencies.” This work motivates the puzzles, explains why resolving them should be part of long-term responses to COVID-19, and outlines some initial COVID-19-related findings that shed light on justifiable authority allocation, emergencies, emergency powers, and the relationships between them.

Sustainable Marketing

Current changes in the business environment mean that the pursuit of economic development—without accounting for social welfare and environmental constraints—is replaced by the concept of sustainable development. Enterprises, in order to meet market requirements, adopt sustainable marketing as part of their strategy to provide long-term benefits in the social, economic, and environmental dimensions. The article aims to assess the differences in the use of marketing mix tools (5P) according to the concept of sustainable development in countries with different socioeconomic conditions. The empirical study was based on 262 questionnaires conducted among small and medium-sized enterprises (SMEs) operating in two different countries, i.e., 150 companies operating in Poland (as an example of a developed country) and 112 in Sri Lanka (as an example of a developing country). The obtained results show that there are statistically significant differences between the analyzed markets in terms of implementing sustainable marketing tools. The results allow us to conclude that the sustainable marketing mix activities are significantly more important for SEM managers in Sri Lanka than in Poland.

The results of 5 years operation of 8 full-scale up-flow aerated Biofor® biofilters, installed at the West Basin Recycling Plant treatment plant (California), demonstrated the efficiency and reliability of this technology in the production of high quality ammonia free water for industrial reuse as cooling water in oil refineries. High nitrification rates up to 0.75 kg d−1 m−3 (0.047 lb d−1 ft−3) were obtained atwater velocities of 6.7 m h−1 (867.5 gpm). The hydraulic retention time in the biofilters was short without any negative consequences on the process. During all five years of operation, all Biofor® units demonstrated very reliable performances with 100% ammonia removal efficiency and very low residual suspended solids concentration of about 4.0 mg TSS L−1.

By adopting the chaîne opératoire approach as a dynamic theoretical and methodological framework for studying ancient technologies, this paper investigates the modalities behind the appearance of the potter's wheel in the Aegean during the Early Bronze Age II (c. 2550–2200 bc). Based on the comparative examination of ceramic assemblages from different Aegean sites, an extended technological study has been carried out in order to track the earliest wheel-made pottery and reconstruct the craft behaviours perpetrated by the use of the potter's wheel across the Aegean. The paper presents the results of this multi-site study and aims to (a) trace out the wheel-based technological traditions, (b) explore the contexts of the learning and transmission of the new tool, (c) shed light on the connectivity among Aegean and western Anatolian communities that enabled the transfer of the new craft knowledge, and, finally, (d) bring into view the mechanisms behind its emergence and appropriation. By considering technologies as representing an entire social system of knowing, perceiving and acting on the material world, it will be argued that the spread of the potter's wheel in the Aegean does not reflect a moment of linear diffusion of a technological innovation, adopted thanks to certain techno-functional advantages. Instead, it discloses the resilience of social identities and values embedded through the practical engagement of individuals in the production of their material culture. The potter's wheel, in fact, emerges as a socially and culturally mediated practice, specific to small groups of potters trained within a technological tradition of Anatolian origin, performing their craft in the Aegean socio-cultural milieus. Furthermore, its transfer reveals a multidirectional and dynamic crossing of material cultures that designated a navigable world where traditions, objects and people travelled, mixed and merged in unpredictable ways.

We live in an age characterized by increasing environmental, social, economic, and political uncertainty. Human societies face significant challenges, ranging from climate change to food security, biodiversity declines and extinction, and political instability. In response, scientists, policy makers, and the general public are seeking new interdisciplinary or transdisciplinary approaches to evaluate and identify meaningful solutions to these global challenges. Underrecognized among these challenges is the disappearing record of past environmental change, which can be key to surviving the future. Historical sciences such as archaeology access the past to provide long-term perspectives on past human ecodynamics: the interaction between human social and cultural systems and climate and environment. Such studies shed light on how we arrived at the present day and help us search for sustainable trajectories toward the future. Here, we highlight contributions by archaeology—the study of the human past—to interdisciplinary research programs designed to evaluate current social and environmental challenges and contribute to solutions for the future. The past is a multimillennial experiment in human ecodynamics, and, together with our transdisciplinary colleagues, archaeology is well positioned to uncover the lessons of that experiment.

Over Time

Purpose Business relationships are considered long-term and stable. Furthermore, over time, business relationships are expected to become and remain “institutionalized”. The undertone is that this process is deterministic and inevitable. While the authors do not question the long-term nature of business relationships, they argue that the process of “institutionalization” requires more construct clarity. Consequently, they ask the following: What is the source of resilience in business relationships, and how are these relationships maintained over time? Design/methodology/approach To unravel these questions, the authors conducted an historical case study of a business relationship between a government buyer and a software seller extending over two decades. Findings The authors found that while the network around the business relationship is crumbling and all odds are in favor of relationship dissolution, the active maintenance work of key individuals in the relationship prevented detrimental effects and resulted in not only its continuation but also an increased degree of institutionalization. Research limitations/implications The authors contribute to the Industrial Network approach (INA) by providing a non-deterministic approach to the typically taken-for-granted end phase of business relationships. Practical implications The findings illustrate that the process of institutionalization is manageable but requires hard work, highlighting managers as the principle vehicle of relationship maintenance. Originality/value The authors provide construct clarity around the process of “institutionalization”. In fact, they regard the process as reverse compared to the early interpretation in the INA literature in which a business relationship is assumed to start as a “clean slate” and then begins to represent the industry codes of practice over time. They found that “institutionalization” implies that a business relationship is no longer compared with nor is comparable to the institutional prescriptions; in contrast, the relationship has established its own rules and norms, which have been taken for granted by the buyer and seller organization.
