Climate change can significantly increase massive fish escapes from marine aquaculture facilities as coastal extreme events become more frequent and severe. Despite the significant environmental and economic consequences of fish escapes, regulations and management measures remain scarce worldwide, particularly in Mediterranean areas. This research presents a transdisciplinary evaluation of fish escape management measures in Spain by (i) identifying measures to reduce the impact of massive escape events, (ii) analysing how stakeholders prioritise these measures, and (iii) comparing stakeholders' priorities with consumers' perceptions. For this purpose, two surveys were conducted: one targeting stakeholders directly involved in escape management (aquaculture farmers, fisheries sector, researchers, and public administration officers, n = 97), and another targeting fish consumers (n = 807). Using the Unweighted TOPSIS multicriteria method, six mitigation, contingency and restoration measures were evaluated by stakeholders. Both stakeholders and consumers expressed the strongest support for market transparency measures aimed at preventing food fraud, particularly detailed labelling and information systems for fish escape events, as selling escaped farmed fish as wild-caught is not currently subject to compulsory control or regulation. Improving site selection and relocation of facilities, as well as the adoption of the UNE 173202 standard, are also considered as suitable solutions to minimise the risk of massive fish escapes. An effective escape management framework should combine rapid operational response mechanisms with long-term preventive planning that explicitly accounts for the effects of climate change, while ensuring consumer protection.
This paper aims to help managers in the decision-making process of improving sustainability by implementing joint lean and resilient supply chain strategies. Lean and resilient strategies have a positive impact on sustainability performance and, moreover, there exists a positive relationship between practices pertaining to both strategies in the sense that some of the practices facilitate the implementation of other practices. A decision-making model that improves the company’s sustainability level while maximizing the future impact of the present supply chain strategies’ implementation is developed. Under budgetary constraints, it becomes especially important to take advantage of the existing synergies between supply chain practices’ implementation to decrease the total implementation cost. A case study in the aerospace sector is carried out in order to illustrate the benefits of the proposed model with respect to traditional models found in the literature. The results imply that, under budgetary stress, a sequential implementation of supply chain practices is recommended, and the proposed mathematical model performs more efficiently than traditional models.
This study compared the effects of two pitch sizes (40 × 20 m and 30 × 15 m) on mental workload (MWL), perceived physical effort (RPE), and physical performance during 8-vs-8 small-sided football games (SSGs). Sixteen amateur players (an average age of 13.95 years) participated in a cross-over design over three weeks, playing on both pitch sizes. Pre- and post-tests measured neuromuscular fatigue via countermovement jumps (CMJ), the RPE scale, and MWL with the NASA-TLX. VO2Max was assessed once to explore its relationship with MWL changes. Results showed a significant effect of time on neuromuscular fatigue and a significant pitch size effect on RPE, with a 9.39
Purpose This study investigated the role of stakeholder pressure (SPRE) as a key driver of circular business model (CBM) adoption in Ecuador's manufacturing sectors. It further explored how Industry 4.0 technologies (I4.0T) and organizational agility (OA) act as mediators in this process, enabling organizations to navigate the transition toward a CBM more effectively. Design/methodology/approach A theoretical framework was developed, incorporating CBM, SPRE, OA and I4.0T. Empirical data were collected through a survey of 150 organizations in Ecuador. The study employed partial least squares structural equation modeling (PLS-SEM) based on established measurement models to analyze the relationships among these variables. Findings The results showed a significant influence of SPRE on CBM adoption. Furthermore, I4.0T acted as a mediator in the relationship between SPRE and CBM adoption, while OA played a similar role in the link between SPRE and CBM. Furthermore, the findings highlight the impact of I4.0T in optimizing product design and traceability, which accelerates the transition to a circular economy (CE). In addition, OA strengthens the adaptive capacity of organizations, enabling them to proactively align with CBM. Originality/value This research addressed a critical gap in understanding the interplay of stakeholder dynamics, technological innovation and agility in CBM adoption. It provides empirical evidence on the mediating role of I4.0T and OA, offering valuable insights for organizations seeking to transition toward CBM.
The relationship between soccer players' match performance and cumulative training loads needs to be analysed. Therefore, the objectives of this study were: 1) to examine the influence of accumulated weekly training loads on subsequent mechanical match outcomes, and 2) to analyze individual variability in training and match loads using the coefficient of variation (CV) throughout the season. Internal and external loads over the entire season of 22 semi-professional soccer players (age 23.2 ± 4.2 years, body mass 75.0 ± 5.8 kg, and body height 1.79 ± 0.06 m) were analyzed. The devices used were 10-Hz Playertek+ GPS/GNSS units equipped with an inertial system and an accelerometer (Catapult Innovations, Melbourne, Australia) and the Borg scale in its 6-20 points version. The analysis of the data with the entire squad included all demarcations (except goalkeepers), however, in a second analysis players with the highest participation throughout the season were included, i.e., six defenders (three center back and three fullback players), three midfielders and three forwards (two wingers and one striker). Match high-speed running (HSR) showed significant correlations with most of the variables analyzed (r = 0.14-0.52). Training load variables analyzed (14.7-64.5%) exhibited larger CV values than those observed in matches (4.4-31.8%). Players with greater match HSR showed superior accumulated HSR during the week before the match than those who presented less match HSR (p = 0.024). The cumulative training load indicates a direct relationship with match HSR performance acutely and chronically. Thus, coaches should design tasks emphasizing HSR accumulation throughout the season.
