Purpose The purpose of this study is to examine supplier financial risk through the lens of Enactment Theory, to explore the role of transparency and communication on buyers’ perceptions of supplier default risk. The authors develop a theoretical model proposing that buyer communication with suppliers leads to preemptive actions that may prevent supplier financial default and fewer supply disruptions. The results suggest that reducing equivocality in buyers through communication with suppliers leads to understanding of financial factors not captured through third-party financial indicators, leading to proactive risk mitigation activities that prevent disruptions during recessionary economic cycles. This research proposes that transparency and communication reduces equivocality in buyers, spurring them to take contractual actions that reduces, financial default in key suppliers, which leads to fewer supply disruptions. Design/methodology/approach Survey data collected from 175 firms in the North America and Brazil during a period of the global recession is used to test the impact of communication with suppliers on supply chain disruptions in periods of economic crisis. This relationship is mediated by proactive contract renegotiation and supplier financial health, supporting a model grounded in Enactment Theory. Findings Results show that buyers who regularly assess and develop an understanding of their key suppliers’ financial conditions are more likely to re-negotiate contracts that revise payment terms, leading to improved supplier working capital and fewer supply chain disruptions. Research limitations/implications Validation of industry-specific financial ratios and figures could provide a richer set of insights and some quantitative measures for establishing baseline on what levels of financial ratios actually result in disruptions. However, future research should consider using a cross-sectional sample and, in addition, a qualitative approach to capture risk from a greater variety of industries and supply chain dynamics. Originality/value The notion of effective communication flows as a means for reduction of supplier disruption risk is aligned with Enactment Theory views that emphasize the benefits of risk reduction. Equivocality is reduced in buyers through information exchange and formal assessments in complex environments. This research suggests that while such communication does not have a direct effect on supply disruption risk, it is mediated through proactive buyer actions to improve supplier financial health and contract re-negotiation mechanisms that may preempt financial distress. These are important lessons learned that provide guidelines for supply chain executives in future economic recessions that may occur in the coming years.

PurposeThe impact of supply disruptions from unplanned events can cause goods shortage, limited responsiveness and high opportunity cost thus compromising development aid programmes' achievement targets. These situations force humanitarian aid agencies to develop new strategies for effectively managing their supplies. The purpose of this paper is to illustrate the foundation of humanitarian supply chain resilience through the development of an adapted Kraljic portfolio model.Design/methodology/approachAction research was used to adapt and validate the Kraljic portfolio model to the development aid context. The research team worked with a humanitarian aid agency in developing criterions and used Analytical Hierarchical Process (AHP) in weighting those key criterions.FindingsThe adapted portfolio model was able to evaluate purchases done by the aid agency by incorporating different perspectives related to the strategic importance of purchase and supply vulnerability. In particular, development aid programmes require large supplies annually. Better classification offers improved visualisation of purchases, leading to a more precise adoption of mitigation strategies and policies to minimise supply disruption risks.Research limitations/implicationsAdapting the Kraljic portfolio model is a stepping-stone to building humanitarian supply chain resilience. The proposed humanitarian supply chain resilience framework is based on the foundation that current humanitarian supply chain needs to be re-engineered. In order to re-engineer, the supply base strategy must first be revisited.Practical implicationsMany aid agencies do not have a holistic view on their purchases and commonly apply a transactional classification of purchases that only considers the consumption values. Purchasing strategies mostly focus on cost minimisation, whereas risk mitigations have been disregarded. The proposed portfolio model overcomes these drawbacks. Societal impact may be limited but development aid agencies will be able to offer more reliable aid delivery as part of their mandate.Originality/valueThe proposed portfolio model is among the first tool to guide humanitarian aid agencies to develop procurement strategies to alleviate supply disruptions and increase development aid programmes resilience.

The rise in global oil prices observed since September 2010 results in part from the social and political instability in the Middle East and North African regions, and in part from longer-term trends reasserting themselves. The unrest sweeping Tunisia earlier this year spread over many surrounding nations, including some major oil producers, such as Algeria and, most significantly, Libya. The Middle East currently supplies about a third of world oil and possesses over half of the world's proven reserves. Clearly, instability in the region automatically raises worries of supply disruptions and possible oil shortage, stimulating speculation and driving world oil prices to new peaks. Speculators have a tendency to overshoot the impact of a supply shock, and in any case supply-driven spikes should remain temporary, fading away as political stability returns.

Rural communities are disproportionally affected by food insecurity, making them vulnerable to the consequences of supply disruptions caused by the COVID-19 pandemic. While access to food was initially diminished due to food supply disruptions, little is known about the mechanisms through which federal emergency assistance programs impacted food access in rural populations. Through a series of five focus groups in spring 2021, we examined the impact of the COVID-19 pandemic on food access in a rural Appalachian community in Kentucky. Data were analyzed using a Grounded Theory Approach. Findings revealed the following four primary themes: food scarcity in grocery stores; expanded federal food assistance; expanded community food resources; and expanded home gardening. Participants provided details regarding the way increased federal assistance, especially expanded benefits within the Supplemental Nutrition Assistance Program, allowed them to purchase greater quantities of nutritious food. This study unveils the specific impacts of the COVID-19 pandemic on one rural population, including the influence of some social determinants of health on food insecurity. Policymakers and stakeholders should recognize the layered protection of multiple federal emergency assistance programs against food insecurity and the potential for long-term population health promotion in rural areas.

We have modeled a new (Q, r) inventory system which involves a single product, a supplier, and a retailer with customer differentiation under continuous review inventory policy. The supplier provides the retailer with all requirements, and the retailer sells products to the customers. The supplying process is randomly subject to disruptions. Partial backordering is applied when a stock out occurs, and customer can select either to leave the system without purchasing or to backorder products. The customers are categorized into two main classes regarding to their backordering probabilities. The main contribution of this paper is including the customer differentiation in the inventory model. We used simulation technique to verify the impact of supply disruptions and customer differentiation and carried out sensitivity analysis. To test the performance of the model, we have compared our model to one from the latest related research. As the results show, the average of total annual cost of the (Q, r) inventory system is lower than that of the previously developed models such as (r, T) inventory systems.

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.
