The focus of the present paper is the development of a resilience framework suitable to be applied in assessing the safety of ship LNG (Liquefied Natural Gas) bunkering process. Ship propulsion considering LNG as a possible fuel (with dual fuel marine engines installed on board) has favored important discussions about the LNG supply chain and delivery on board to the ship power plant. Within this context, a resilience methodological approach is outlined, including a case study application, to demonstrate its actual effectiveness. With specific reference to the operative steps for LNG bunkering operations in the maritime field, a dynamic model based on Bayesian inference and MCMC simulations can be built, involving the probability of operational perturbations, together with their updates based on the hard (failures) and soft (process variables deviations) evidence emerging during LNG bunkering operations. The approach developed in this work, based on advanced Markov Models and variational fitting algorithms, has proven to be a useful and flexible tool to study, analyze and verify how much the perturbations of systems and subsystems can be absorbed without leading to failure.

A critical examination is undertaken of a new set of data—the 1991 Census of Population samples of anonymised records (SARs)—as an instrument for improving the quality of the indices used in the English Standard Spending Assessments system for the allocation of central government funds to local authorities. The ‘additional education needs' index is used as a case study. Application of the Department of the Environment's existing methodological approach in conjunction with the SARs produces significant improvements in the explanatory power of the regression-based models. It is concluded that the SARs represent an invaluable source of data to supplement or replace the databases currently utilised in the standard spending assessment indices. The implications of this for the 2001 Census of Population are also identified and discussed.

This paper presents the early results of a study aimed at experimenting an innovative approach to the design and the evaluation of complex urban transformation processes, based on the combined use of different design strategies and tools. The purpose of the paper is to illustrate, by means of a case study, a multi-level decision aiding process, able to support strategic urban design, with specific reference to regeneration processes for abandoned industrial sites in urban areas. The case study presented in the paper concerns different alternative proposals for the requalification of the former Shougang/Er-Tong mechanical factory in Beijing, China. The choice of a Chinese case study as a field test for an experimentation about mixed methods research approaches in the domain of urban transformation is related to the peculiar emerging conditions of that context, in which huge economic potentials are speeding up the transformation but a substantial lack of cultural and methodological instruments to manage a so fast modification exists. During the design process, three methods in particular have been combined according to a multi-phase design: (i) Stakeholders Analysis, (ii) Multicriteria Analysis, and (iii) Discounted Cash Flow Analysis. Each one of them has been applied in parallel to the evolution of the different design scenarios. The results of the performed study show that mixed methods approaches are a promising line of research in the field of environmental evaluation and urban design. Insights and guidelines for the replication of the proposed methodological approach in other territorial contexts are also proposed.

We propose a penalized likelihood approach in hidden Markov models (HMMs) to perform automated variable selection. To account for a potential large number of covariates, which also may be substantially correlated, we consider the elastic net penalty containing LASSO and ridge as special cases. By quadratically approximating the non-differentiable penalty, we ensure that the likelihood can be maximized numerically. The feasibility of our approach is assessed in simulation experiments. As a case study, we examine the ‘hot hand’ effect, whose existence is highly debated in different fields, such as psychology and economics. In the present work, we investigate a potential ‘hot shoe’ effect for the performance of penalty takers in (association) football, where the (latent) states of the HMM serve for the underlying form of a player.

Abstract Advances in sociophonetic research resulted in features once sorted into discrete bins now being measured continuously. This has implied a shift in what sociolinguists view as the abstract representation of the sociolinguistic variable. When measured discretely, variation is variation in selection: one variant is selected for production, and factors influencing language variation and change are influencing the frequency at which variants are selected. Measured continuously, variation is variation in execution: speakers have a single target for production, which they approximate with varying success. This paper suggests that both approaches can and should be considered in sociophonetic analysis. To that end, I offer the use of hidden Markov models (HMMs) as a novel approach to find speakers’ multiple targets within continuous data. Using the lot vowel among whites in Greater St. Louis as a case study, I compare 2-state and 1-state HMMs constructed at the individual speaker level. Ten of fifty-two speakers’ production is shown to involve the regular use of distinct fronted and backed variants of the vowel. This finding illustrates HMMs’ capacity to allow us to consider variation as both variant selection and execution, making them a useful tool in the analysis of sociophonetic data.

Covid-19 has had a significant impact on the disruption of the global economic sector, including for startup businesses. This encourages entrepreneurs to carry out a continuous innovation process to become more ambidextrous and continue to innovate in an effort to futureproof their business. The paper aims to provide a business resilience framework by exploring capability (innovation ambidexterity, dynamic capability, and technology capability), behavior (agile leadership), and knowledge (knowledge stock) in startup businesses. This study uses a literature review synthesis to gain a greater understanding of startup resilience and its implementation. This study also uses a case study approach in building a framework by obtaining data from semi-structured interviews with three startups owners in Indonesia. This preliminary research has identified four propositions that will be used to develop questionnaires and data collection instruments. Thus, this study provides new insights on how startups can overcome contradictory pressures for business resilience in anticipating, dealing with, and emerging from business turbulence due to the Covid-19 pandemic by considering the factors proposed in this study. The implications and recommendations of this study are also discussed in detail.

Abstract Background Core outcome sets (COS) should be relevant to key stakeholders and widely applicable and usable. Ideally, they are developed for international use to allow optimal data synthesis from trials. Electronic Delphi surveys are commonly used to facilitate global participation; however, this has limitations. It is common for these surveys to be conducted in a single language potentially excluding those not fluent in that tongue. The aim of this study is to summarise current approaches for optimising international participation in Delphi studies and make recommendations for future practice. Methods A comprehensive literature review of current approaches to translating Delphi surveys for COS development was undertaken. A standardised methodology adapted from international guidance derived from 12 major sets of translation guidelines in the field of outcome reporting was developed. As a case study, this was applied to a COS project for surgical trials in gastric cancer to translate a Delphi survey into 7 target languages from regions active in gastric cancer research. Results Three hundred thirty-two abstracts were screened and four studies addressing COS development in rheumatoid and osteoarthritis, vascular malformations and polypharmacy were eligible for inclusion. There was wide variation in methodological approaches to translation, including the number of forward translations, the inclusion of back translation, the employment of cognitive debriefing and how discrepancies and disagreements were handled. Important considerations were identified during the development of the gastric cancer survey including establishing translation groups, timelines, understanding financial implications, strategies to maximise recruitment and regulatory approvals. The methodological approach to translating the Delphi surveys was easily reproducible by local collaborators and resulted in an additional 637 participants to the 315 recruited to complete the source language survey. Ninety-nine per cent of patients and 97% of healthcare professionals from non-English-speaking regions used translated surveys. Conclusion Consideration of the issues described will improve planning by other COS developers and can be used to widen international participation from both patients and healthcare professionals.
