Abstract In ungauged or data-scarce watersheds, systematic analyses of a set of proximate watersheds (for example, selected based on locational proximity or similarity in climate, morphometry, lithology, soils, and vegetation) have been shown to lend significant insights regarding hydrologic response and prediction. Current approaches often rely on: (a) statistical regression models that use measurable watershed attributes, such as area, slope, and stream length; and (b) comparative hydrology that considers watershed characteristics to assess hydrologic similarity to select analogous gauged watersheds as proxies. Newer conceptions regarding hydrologic similarity focus on hydrologic response and therefore emphasize the use of dynamical measures of the stream network and watershed terrain. For example, the width function and hypsometric curve can be readily estimated using the available global digital terrain datasets and represented as functional forms involving a small set of parameters, thus achieving significant data reduction. In this study, a new approach to hydrological similarity in watersheds, one that utilizes these functional forms to identify dynamically similar watersheds, is presented. Dissimilarity matrices are created based on divergence measures, and watersheds are classified using hierarchical clustering. The joint analysis of watershed width functions and hypsometric curves allows for the classification of watersheds into a reduced number of dynamically-similar groups. An illustrative case study for the Narmada River, with 72 sub-watersheds, is presented.

Resilient socioeconomic unsustainability poses a threat to democracy whose importance has yet to be fully acknowledged. As the prospect of sustainability transition wanes, so does perceived legitimacy of institutions. This further limits representative institutions’ ability to take action, making democratic deepening all the more urgent. I investigate this argument through an illustrative case study, the 2017 People’s Climate March. In a context of resilient unsustainability, protesters have little expectation that institutions might address the ecological crisis and this view is likely to spread. New ways of thinking about this problem and a new research agenda are needed.

Although teaching reflection diaries (TRDs) are prevalent tools for teacher training, TRDs are rarely used in Japanese secondary educational settings. In order to delve into the effects of TRDs on teaching development, this illustrative case study was conducted with two female teachers (one novice, and one experienced) at a Japanese private senior high school. The research findings demonstrated that both in-service teachers perceived TRDs as beneficial tools for understanding their strengths and weaknesses. TRDs and class observations illustrated that the novice teacher raised their self-confidence in teaching and gradually changed their teaching activities. On the other hand, the experienced teacher held firm teaching beliefs based on their successful teaching experiences and were sometimes less willing to experiment with different approaches. However, they changed their teaching approaches when they lost balance between their class preparation and other duties. Accordingly, although teachers’ firm beliefs and successful experiences may sometimes become possible hindrances from using TRDs effectively, TRDs can be useful tools to train and help teachers realise their strengths and weaknesses.

Purpose A new conceptualization of the process of country of origin (COO) branding based on fresh theoretical foundations is developed. This paper aims to provide a strategic perspective that integrates extant views of COO branding, based on identity and image, with a relational perspective based on a process approach to developing collective brand meaning. Design/methodology/approach A systematic review of the literature on COO branding and geographical indicators is undertaken, together with a review of contemporary research on branding. Our framework conceptualizes COO branding as an integrating process that aligns a network of relationships to co-create collective meaning for the brand’s value propositions. Findings An illustrative case study provides empirical evidence to support the new theoretical framework. Research limitations/implications Issues for further research include exploring and refining the theoretical framework in other research contexts and investigating broader issues about how COO branding influences self and collective interests in business relationships and industry networks. Practical implications Adopting a broadened perspective of COO branding enables managers to understand how identity and image are integrated with their business relationships in the context of developing collective brand meaning. Providing a sustained strategic advantage for all network actors, an integrated COO branding process extends beyond developing a distinctive identity and image. Originality/value Accepted consumer, product, firm and place level perspectives of COO branding are challenged by developing and verifying a new integrated conceptualization of branding.

Customers’ pressure, social responsibility, and government regulations have motivated the enterprises to consider the reverse logistics (RL) in their operations. Recently, companies frequently outsource their RL practices to third-party reverse logistics providers (3PRLPs) to concentrate on their primary concern and diminish costs. However, to select the suitable 3PRLP candidate requires a multi-criteria decision making (MCDM) process involving uncertainty owing to the presence of many associated aspects. In order to choose the most appropriate sustainable 3PRLP (S3PRLP), we introduce a hybrid approach based on the classical Combined Compromise Solution (CoCoSo) method and propose a discrimination measure within the context of hesitant fuzzy sets (HFSs). This approach offers a new process based on the discrimination measure for evaluating the criteria weights. The efficiency and practicability of the present approach are numerically demonstrated by solving an illustrative case study of S3PRLPs selection under a hesitant fuzzy environment. Moreover, sensitivity and comparative studies are presented to highlight the robustness and strength of the introduced methodology. The result of this work concludes that the introduced methodology can recommend a more feasible performance when facing with determinate and inconsistent knowledge and qualitative data.

An industrial strategy emerges from possibilities for structural change, that depend on material constraints and opportunities afforded by economic structure, the distribution of power in society and the institutional arrangements organized at the political level. Building on a structural political economy perspective, this article develops a structure–power–institutions conceptual framework to describe how economic structure, the distribution of power, and institutions interact through a ‘circular process,’ which is useful for analysing the historical transformation of industrial strategy. In this framework, an industrial strategy refers to the institutional arrangements through which the government manages emerging conflicts or agreements between different powers and influences structural change. As an illustrative case study, the structure–power–institutions framework is applied to analyse the historical transformation of US industrial strategy from the era of Alexander Hamilton to that of Donald Trump.
