Addressing the critical challenge of Scope 3 emissions, this research investigates the dynamics between a French food MNE’s UK subsidiary (Company X) in UK, acting as a Tier 1 supplier, and its lower-tier suppliers in Scotland and Norway. We explore how do multinational enterprise subsidiaries act as bridging mechanisms to mediate sustainability mandates and local institutional contexts, driving environmental upgrading and addressing Scope 3 emissions in the context of salmon value chains. Through qualitative analysis of interviews and secondary data, the findings highlight the subsidiary’s bridging role in reconciling global corporate mandates with local institutional pressures. Institutional context plays a defining role in shaping subsidiary’s bridging strategy with divergent implications for Scottish and Norwegian suppliers environmental upgradin 2026-10-16T00:00:00Z http://hdl.handle.net/1893/38392 Title: A stage-weighted environmental risk and visual severity integration model for climate-smart management of cassava anthracnose in humid tropical systems Author(s): Bulut, Cevdet; Onwona-Hwesofour Asante, Kwaku; Akon-Yamga, Gordon; Adu-Gyamfi, Monica Ode; Appiah-Kubi, Zippora; Odame Afari, Sarah; Brett, Josua; Onwona Simpe, Kwame; Nutefe Kuavedzi, Reuben Abstract: Colletotrichum anthracnose is a persistent constraint on cassava root yield and planting material quality in humid tropical systems, where calendar-based management often leads to poorly timed or excessive fungicide use. This study developed and pilot-tested the Cassava Anthracnose Risk Index (CARI), a stage-sensitive, persistence-adjusted early-warning framework integrating low-cost environmental sensing with structured visual severity scoring for climate-smart, input-reduced disease management. Microclimate sensors were deployed at CSIR-CRI Fumesua, Ghana, across a 13-month rainfed crop cycle (March 2025 – April 2026) using the susceptible landrace Debo. A stage-weighted Environmental Risk Subscore (ERS; 0–600 points, ERS%) was constructed from six environmental components, moderated by a persistence factor requiring sustained infection-favorable conditions, and stratified across three growth stages. A Visual Symptom Subscore (VSS; 0–40) was derived from standardised weekly severity assessments of 15 sentinel plants, integrated into a composite CARI (0–100) with stage-specific alert thresholds. Across 73 valid Stage 3 monitoring days, CARI classified all observations as Low Risk and issued no Amber or Red alerts, including on 37 of 73 days with sustained nocturnal high-humidity conditions that would have triggered a precautionary alert under a simple threshold approach. In the single confirmed disease episode observed, an approximately one-day interval separated the highest environmental risk signal from confirmed symptom onset; this is not presented as a validated lag value, a preceding 25-day sensor outage means antecedent conditions cannot be characterised. CARI did not issue an intervention recommendation during this episode (11–24 February 2026) because concurrent environmental risk remained below the Amber threshold. Published decision support systems for Colletotrichum anthracnose in other pathosystems report fungicide reductions of 30–70% relative to calendar-based approaches; these figures are cited only for benchmarking and were not measured here, as no comparative fungicide trial was conducted. These results provide proof of concept for the technical operability of CARI and identify the dataset and analyses required for formal predictive evaluation in a planned multi-season study; they should not be interpreted as evidence of CARI’s predictive accuracy or input-reduction performance. 2026-10-06T00:00:00Z http://hdl.handle.net/1893/38377 Title: Do Professionals Choke in the Face of Pressure and Distraction? Author(s): Butler, David; Butler, Robert; Singleton, Carl Abstract: We ask whether facing partisan audiences affects the execution of a skilled task. Our setting is penalty shootouts in the high-stakes environment of elite professional football (soccer). In this context, performers take penalties under intense pressure, while facing a subset of the crowd behind the goal who attempt to distract them through visual and auditory tactics. Using data on 1,322 penalties taken in the later rounds of major English cup competitions from 1992 to 2026, we find no evidence that having supportive allied spectators behind the goal provides a strategic advantage. This implies that elite professionals in this domain can effectively screen out crowd-induced distractions when performing under extreme stress. 2026-12-01T00:00:00Z http://hdl.handle.net/1893/38320 Title: Inference in downstream analysis using individual-level posterior means from mixed logit models Author(s): Campbell, Danny; Sandorf, Erlend Dancke; Börger, Tobias; Dekker, Thijs Abstract: Mixed logit models are widely used to recover individual-level preferences for secondary analysis, yet both first-stage sampling uncertainty and variability in conditional distributions are often overlooked. This technical note illustrates the implications of ignoring these sources of uncertainty and provides reproducible R code, compatible with the apollo package, to better approximate the empirical sampling distribution and improve the reliability of second-stage inference. 2026-09-01T00:00:00Z
