Association for Supply Chain Management, Procurement and Logistics

Purpose The study investigates stakeholder engagement in public procurement of works within tertiary institutions in Ghana, emphasizing its role in advancing environmental sustainability. It aims to determine the present level of stakeholder engagement, assess stakeholders' understanding of environmental sustainability and explore barriers hindering effective engagement. Design/methodology/approach Structured questionnaires were administered to procurement professionals, stakeholders and institutional representatives. Data was analysed using descriptive statistics, one-sample t-test, and mean score ranking to identify patterns, levels and barriers to stakeholder engagement. Findings The results highlight that stakeholder engagement is most prominent at the preparation and planning stage, while later procurement phases, such as tendering and contract implementation, experience reduced participation. Stakeholders demonstrated a generally high understanding of environmental sustainability. However, significant barriers were identified, including difficulty in identifying representatives, lack of clear benefits and financial constraints. These systemic and resource-related challenges limit comprehensive stakeholder involvement across procurement phases. Practical implications The findings emphasize the need for tertiary institutions to adopt comprehensive stakeholder mapping, implement structured engagement frameworks and promote transparency. Tailored training programs and adequate resource allocation are necessary to overcome identified barriers and ensure sustainable procurement practices. Originality/value This study offers new insights into stakeholder engagement in Ghana's tertiary institutions, providing a localized understanding of the interplay between procurement practices and environmental sustainability. It proposes practical strategies to enhance participation and sustainability outcomes, aligning procurement processes with global best practices.

Abstract Research on blockchain technology in supply chain management has gained significant attention in recent years due to its potential to address critical challenges such as transparency, traceability, and operational efficiency. Despite this interest, the relationship between blockchain implementation and its measurable success has not been thoroughly investigated. This study conducts a systematic literature review of 46 peer-reviewed papers published between 2008 and 2024, synthesizing current research on how blockchain performance is assessed within supply chains. By categorizing the findings across key success factors, research methodologies, and performance indicators, this study provides a structured understanding of blockchain’s role in SCM. Emerging from our review, we develop a dynamic evaluation framework that systematically integrates use cases, objectives, input criteria, research methodologies, and expected outcomes, illustrating their interdependencies. This framework demonstrates blockchain’s capacity to enhance supply chain performance through improved transparency, enhanced traceability, and strengthened sustainability practices. Furthermore, it provides a structured approach to assessing blockchain’s long-term viability, emphasizing its iterative nature, which allows organizations to refine and adapt their implementations in response to evolving business and regulatory landscapes. Our findings underscore the cross-industry applicability of blockchain technology, spanning various sectors and bridging both operational and strategic objectives. However, the analysis reveals significant research gaps, particularly in empirical studies validating blockchain’s long-term impact on supply chain resilience, sustainability, and multi-stakeholder collaboration. Additionally, inconsistencies in performance measurement approaches hinder the comparability of findings across studies. Addressing these gaps through future research will be essential to fully unlocking blockchain’s transformative potential in SCM and ensuring its effective integration into global supply chain ecosystems.

Die Schatzungen fur das jahrliche Beschaffungsvolumen offentlicher Auftraggeber der Bundesrepublik Deutschland belaufen sich zwischen 260 Mrd. Euro und 480 Mrd. Euro. Die EU-Kommission beziffert das Beschaffungsvolumen in Deutschland fur das Jahr 2010 auf 480 Mrd. Euro und in der EU auf 2,41 Billionen Euro [30]. Dies entspricht einem Anteil von etwa 19% am Bruttoinlandsprodukt der EU-27-Staaten, was die wirtschaftliche Bedeutung des offentlichen Auftragswesens unterstreicht. Die Bedeutung des offentlichen Beschaffungswesens ist sogar noch groser, wenn nicht nur der Anteil des offentlichen Sektors an den Ausgaben fur Waren und Dienstleistungen insgesamt betrachtet wird, sondern auch bestimmte Branchen bzw. Wirtschaftszweige berucksichtigt werden. In der Baubranche erreicht der Anteil der offentlichen Ausgaben zum Beispiel 40% des Gesamtvolumens; in der Verteidigung und zivilen Sicherheit betragt er fast 100% [31].

Frankfurt ist die einzige Stadt in Deutschland, die seit 10 Jahren ein jährliches Drogenmonitoring erstellen lässt. Es wird im Auftrag des städtischen Drogenreferats vom Centre for Drug Research der Universität Frankfurt ausgeführt. Das Monitoring beinhaltet auch eine repräsentative Befragung der 15- bis 18-jährigen Frankfurter Schülerinnen und Schüler zu ihrem Drogenkonsum und Freizeitverhalten. Diese Befragung ist Grundlage für die Planungen des Drogenreferats im Bereich Suchtprävention. Das Monitoring und die wichtigsten Erkenntnisse und Schlussfolgerungen werden einleitend kurz vorgestellt.

Two decades of survey research has shown that transit‐time differences among ocean carriers are often secondary considerations in carrier selection. However, this study found that shippers can pay substantial premiums for superior ocean transit‐time service, and cut logistics costs even when substantial variability occurs in landside segments of supply chains.
