Studies have shown that monolithic 3D ( M3D ) ICs outperform the existing through-silicon-via ( TSV ) -based 3D ICs in terms of power, performance, and area ( PPA ) metrics, primarily due to the orders of magnitude denser vertical interconnections offered by the nano-scale monolithic inter-tier vias. In order to facilitate faster industry adoption of the M3D technologies, physical design tools and methodologies are essential. Recent academic efforts in developing an EDA algorithm for 3D ICs, mainly targeting placement using TSVs, are inadequate to provide commercial-quality GDS layouts. Lately, pseudo-3D approaches have been devised, which utilize commercial 2D IC EDA engines with tricks that help them operate as an efficient 3D IC CAD tool. In this article, we provide thorough discussions and fair comparisons (both qualitative and quantitative) of the state-of-the-art pseudo-3D design flows, with analysis of limitations in each design flow and solutions to improve their PPA metrics. Moreover, we suggest a hybrid pseudo-3D design flow that achieves both benefits. Our enhancements and the inter-mixed design flow, provide up to an additional 26% wirelength, 10% power consumption, and 23% of power-delay-product improvements.

Purpose The purpose of this study is to examine psychological ownership (PO) experienced by followers of social media influencers toward both influencer and the product. Design/methodology/approach Data were collected using face-to-face semi-structured interviews that were conducted with 30 respondents and analyzed using thematic analysis. Findings The study demonstrated that the PO experienced by the follower changes under different conditions resulting from perceived value, social currency and follower activity. Social currency plays a vital role in determining the target of PO, often affecting the narrative by the follower. Originality/value To the best of the author’s knowledge, this is the first paper to examine the transference of PO between product and influencer as experienced by the follower. It provides an understanding on PO that is experienced in different levels of intensity and changes depending on the motive of the follower; hence, transference of PO occurs and it is not a static.

Purpose The authors wanted to examine why undeclared workers had not received financial assistance in Europe during the pandemic and find the best way to help them and bring them out of the shadows. Design/methodology/approach To identify those whose paid work is entirely undeclared, a Eurobarometer survey of undeclared work in Europe is reported conducted in September 2019, just prior to the pandemic, and involving 27,565 face-to-face interviews in 28 European countries. Findings The paid work of one in every 132 citizens in Europe comprises wholly of undeclared work and one in 28 work at least some of the time in the undeclared economy. These workers have received no support, but they are more likely to be financially vulnerable. A high percentage of undeclared workers are widowed, divorced and living in households with multiple persons. Originality/value The authors argue that short-term support for these individuals could not only help them to survive the pandemic financially, but also transform undeclared work into declared work with long-term benefits for individuals and the wider economy.

Purpose The purpose of this paper is to provide a commentary on Alex Cockain’s article “De-fusing and re-fusing face-to-face encounters involving autistic persons in Hong Kong”. Design/methodology/approach The commentary considers the issues raised in Cockain’s article primarily from a focus on Goffman’s concept of “stigma”. Cognitive, emotional and behavioural components of stigma are examined and its wider relevance considered. Findings There has been less research on the stigma of learning disability than on that of mental health, despite a very early study of learning disability (Edgerton, 1967) using the concept only four years after the publication of Goffman’s (1963) seminal work. A number of points of relevance of stigma are identified including to social role valorisation, visible and invisible stigmas, the concept of “passing”, microaggression, disablism and labelling. Originality/value The commentary illustrates the relevance of the concept of stigma to other aspects of learning disability and disability scholarship.

Purpose The purpose of this paper is to estimate and analyse the technical efficiency (TE) component of productivity for a sample of winegrowers from the Douro Demarcated Region in Portugal. Design/methodology/approach The data were collected through face-to-face surveys and includes a sample of 110 farmers’ vineyards with specific input-output information and other data about production systems during the year of 2017. The authors use a two-stage data envelopment analysis using bootstrap techniques to obtain TE scores in the farmers’ vineyards and to examine the determinants of its efficiency. Findings The results show that some farmers’ vineyards have a low efficiency level and that there are essential determinants of the production system, which can influence its efficiency. This suggests considerable opportunities for improvement of wine grape productivity through better use of available resources considering the state of technology. Originality/value This work has overcome the lack of data in the farmers’ vineyards, the lack of efficiency studies in the region and also allowed to evaluate the production systems and to assess their impact on efficiency.

Purpose The purpose of this paper is to analyse the factors that make tourist shopping districts successful. Design/methodology/approach In total, 12 sets of face-to-face interviews were conducted in 7 cities on 4 continents in September and October, 2019. In total, 21 individuals participated in the interviews. Interviews were conducted in Bangkok Thailand, Singapore, Melbourne and Brisbane Australia, Ottawa Canada, New York USA (three sets of interviews) and London England (four sets of interviews). Findings The literature focusses on operational issues, while respondents highlighted higher order issues relating primarily to organisational structure, governance and funding. Research limitations/implications The study focusses primarily on English speaking jurisdictions, with the exception of Bangkok. As such, the results may not be generalisable to non-English speaking economies. Practical implications Insights into factors influencing the success of tourism retail shopping districts are highlighted, especially the role of governance and creativity. Social implications The paper indicates that local stakeholders also play a key role in the success of such districts. Originality/value This is the first comprehensive, global study of the factors that make tourism shopping districts successful.

Purpose The purpose of this study was to investigate the adoption and use of electronic document and records management system (EDRMS) in the public service in Namibia and Zimbabwe with the aim of establishing barriers and enablers, and best practices which each country could adopt from the other. Design/methodology/approach This multi-case study was informed by an interpretivist paradigm. Qualitative in nature, the study applied face-to-face interviews as the data collection method, supplemented by documents analysis. The study population was Namibia and Zimbabwe’s public sectors with units of analysis, being the governments’ ministries, offices and agencies which have implemented EDRMS. Findings The paper provides the state of EDRMS implementation in Namibia and Zimbabwe. It establishes how the two countries have implemented EDRMS and factors that have contributed to the success/failure of the implementation in both countries. Originality/value The paper is a response to the need for further research studies on the implementation of EDRMS in various countries.
