The Experiences of Students During COVID-19 School Disruptions

Bullock, Brandi 01 December 2023 (has links) (PDF)
The purpose of this study was to identify the perceptions of educators with respect to student experiences between March 2020 and February 2021 related to academics, social-emotional health, and safety and security. Data collection strategies included one-on-one interviews with 12 educators in one East Tennessee school district. To qualify for the study, participants had to have taught during COVID-19 schooling disruptions and have taught either 1st, 2nd, 3rd, 4th, or 5th grade in the 2022-23 school year. Data analysis was based on Systems Theory (Laszlo & Krippner, 1998) and Change Theory (Fullan, 2020). The results revealed 5 key themes that were consistent among educators participating in the interviews and their perceptions of student experiences: (a) technology, (b) uncertainty, (c) engagement, (d) isolation, and (e) gratitude.

Pharmaceutical supply chain resilience. An exploratory analysis of vulnerabilities and resilience strategies in the face of dynamic disruptions in the UK pharmaceutical supply chain

Yaroson, Emilia V. January 2019 (has links)
Pharmaceutical supply chains are susceptible to disruptions which impact on the operational and financial performance of firms as well as patient safety. This study aimed to explore why the Pharmaceutical Supply Chain (PSC) in the UK is susceptible to the impact of dynamic disruptions and examine how resilience strategies have were employed to reduce the effects of these disruptions. The Complex Adaptive System (CAS) theory was used as a framework in an exploratory research design using mixed-methods. The qualitative data were gathered through 23 semi-structured interviews with key supply chain actors across the PSC in the UK to explore their experiences. The findings from these semi-structured interviews were used to develop a survey which was distributed to a broader spectrum of supply chain actors where the final sample from the survey was (n=106). The data were triangulated to discuss the research findings. The initial results revealed power, conflict and complexities as drivers of vulnerabilities in the PSC. Antecedents for building resilience strategies included visibility, flexibility and joint decision making as recovery strategies and resource sharing as the resistance strategy. CAS provided a systemic approach to understanding PSC resilience rather than in parts. In doing so, it took into consideration the various elements that make up the entire system. Thus, vulnerabilities and resilience strategies were outcomes of the interactions between supply chain actors. The findings demonstrated that CAS, as a theory, provided a framework that was beneficial in exploring and gaining insights into PSC resilience. Also, by combining the two datasets (interviews and survey), an original output was proposed -the Pharmaceutical Supply Chain Resilience Framework (PSCRF)- which was used to recommend resilience strategies suitable for mitigating disruptions in the PSC.

The resilience of the logistics service providers in supply chain disruptions : – A qualitative study of logistic network resilience at Schenker Dedicated Services and Samskip

Eierdal, Navah, Boulton, Jenny January 2022 (has links)
Globalisation and outsourcing have exacerbated the complexity of supply chains (Christopher, 2016). As a result, new business models have emerged to reduce the complexity of the supply chain by utilising supply chain management solutions. These business models serve as links in the supply chain that facilitate the integration of the functions of the primary organisation with those of other organisations. When disruptions occur in the supply chain, several parties are impacted. In this situation, supply chain and risk management methodologies can assist in assessing internal and external aspects during disruptive events. To understand the perspective of logistics service providers, this thesis examines Schenker Dedicated Services and Samskip's perceptions of disruptive events, the effects of these events, and how resilience plans are developed. In this context, a logistics service provider is an underlying link that helps its clients by applying supply chain management strategies such as coordinating, integrating, establishing connections, and cooperating.  We assembled a panel of supply chain practitioners with different roles at third-party and fourth-party logistics companies to investigate these factors. This panel had a role in our qualitative investigation and expressed their perspectives. It was discovered that their views of interruptions in the supply chain are comparable but slightly different. These discrepancies may be attributable to the company's business style, logistical networks, and geographic location. / Globalisering och outsourcing har gjort leveranskedjorna svårare (Christopher, 2016). Följaktligen har det växt fram nya affärsmodeller för att minimera komplexiteten i försörjningskedjan genom försörjningskedjehanterings verktyg. Dessa affärsmodeller fungerar som länkar i försörjningskedjan som i sin tur hjälper till att integrera den primära organisationens funktioner i andra organisationer. När störningar uppstår i försörjningskedjan påverkas många inblandade parter. I detta fall kan tillvägagångssätten för försörjningskedje - och riskhantering hjälpa till att mäta de interna och externa faktorerna under störningar. Schenker Dedicated Services och Samskips utformar den underliggande länken i försörjningskedjan. Detta leder till ett fokus på hanteringen av försörjningskedjan genom att samordna, integrera, upprätta länkar och samarbeta. Genom att undersöka Schenker Dedicated Services och Samskips uppfattning om störande händelser, dess effekter och hur motståndsplaner utformas fastställs logistiktjänsteleverantörernas perspektiv.  För att undersöka dessa faktorer valde vi en grupp av personer som är insatta med roller inom Schenker Dedicated Services som är ett fjärdepartslogistik företag och Samskip som är ett företag med inslag av tredjepartslogistik och fjärdepartslogistiks verksamhet. Gruppen var med i vår kvalitativa studie och delade sina uppfattningar kring ämnet. Det visade sig att de har liknande uppfattningar om störningar i leveranskedjan men med små skillnader. Dessa skillnader kan ha kopplingar till arten av företagets affärsmodell, deras logistiska nätverk såväl som deras geografiska område.

The impact of digital technologies in improving supply chain resilience: An exploratory study in the agri-food industry

Dao, Luong 05 1900 (has links)
Globalization, geopolitics, and socio-economic uncertainties increase supply chain vulnerabilities. Climate changes, natural disasters, and man-made accidents have increased the tension of disturbances. The COVID-19 pandemic has disrupted many supply chains worldwide, putting the agri-food supply chain at a higher risk than ever. Agri-food supply chains face severe and complex challenges due to industry-specific characteristics, such as perishability, short shelf life, long lead time production, and weather dependence. Consumer awareness of having healthy, traceable, and environmentally friendly food products has become an increasing concern, making sustainable development also a vital factor in the agri-food industry. To ensure sustainable development, firms must improve supply chain resilience by discovering, nurturing, and developing resilience capability and competitive advantage. Resilience describes the ability to respond quickly to disruptions and help the supply chain recover. Recently, digital technologies have developed rapidly, supported by the Industrial Revolution 4.0, which plays a crucial role in a company's operations. Digital technologies help promote core resilience competencies such as visibility, collaboration, and agility through typical technologies such as blockchain, artificial intelligence, fifth-generation technology, big data analytics, additive manufacturing, tracking, tracing technologies, etc. This study uses a theoretical framework from dynamic capabilities and extant literature reviews to determine the research gap in the agri-food industry. The study uses mixed methods: a qualitative research method to examine and uncover the role of supply chain resilience in responding to disruptions in the agri-food industry, and a second study used a quantitative method to examine the influence of digital technologies on resilience in the agri-food supply chain. This study confirms the critical role of resilience in the agri-food supply chain and the significance of digital technologies in improving supply chain resilience and firm performance. The study also suggests that a firm should proactively build its resilience capability rather than learn from past disruptions. The findings are useful for academics and practitioners alike, in the acknowledgment of the significant effects of digital technologies on supply chain resilience in the agri-food industry. Some technologies are not agri-food specific but have a place in the industry, while others are tailor made for farming applications. Parties in the agri-food industry must take advantage of Industrial Revolution 4.0 and digital technologies to flourish in the agri-food industry. / Business Administration/Interdisciplinary

Resilience strategies and the pharmaceutical supply chain: the role of agility in mitigating drug shortages

Yaroson, Emilia V., Breen, Liz, Hou, Jiachen, Sowter, Julie January 2019 (has links)
No / Supply chain resilience has been suggested to curb the impact of disruptions on supply chains. While this proposition seems coherent in theory, empirical evidence supporting this is limited, as existing literature has centred on exploring the impact of supply chain resilience on disruptions which are based on set time frames, non-supply chain specific as well as examining non-dynamic disruptive events. This study contends that resilience strategies are dynamic and as such their applications within supply chains differ. Therefore examining the impact of resilience will be appropriate on a dynamic disruption within a specific supply chain. In view of this, the paper examines through existing literature the applicability of agility within the pharmaceutical supply chain when dynamic disruptions like drug shortages occur. The study finds alertness, accessibility, connectivity and visibility as dimensions of supply chain agility that are capable of reducing the impact of drug shortages.

Advancing the Understanding of Pharmaceutical Supply Chain Resilience using Complex Adaptive System (CAS) Theory

Yaroson, Emilia V., Breen, Liz, Hou, Jiachen, Sowter, Julie 04 December 2020 (has links)
Yes / Purpose The objective of this study was to advance our knowledge of pharmaceutical supply chain resilience using Complex Adaptive System theory (CAS). Design/methodology/approach An exploratory research design which adopted a qualitative approach was used to achieve the study’s research objective. Qualitative data were gathered through 23 semi-structured interviews with key supply chain actors across the PSC in the United Kingdom (UK). Findings The findings demonstrate that CAS, as a theory, provides a systemic approach to understanding PSC resilience by taking into consideration the various elements (environment, PSC characteristics, vulnerabilities and resilience strategies) that make up the entire system. It also provides explanations for key findings, like the impact of power, conflict and complexity in the PSC, which are influenced by the interactions between supply chain actors and as such increase its susceptibility to the negative impact of disruption. Furthermore, the antecedents for building resilience strategies were the outcome of the decision-making process referred to as co-evolution from a CAS perspective. Originality/value Based on the data collected, the study was able to reflect on the relationships, interactions and interfaces between actors in the PSC using the CAS theory, which supports the proposition that resilience strategies can be adopted by supply chain actors to enhance this service supply chain. This is a novel empirical study of resilience across multiple levels of the PSC and as such adds valuable new knowledge about the phenomenon and the use of CAS theory as a vehicle for exploration and knowledge construction in other supply chains.

Living with power outages : Urban energy infrastructure disruptions and their impact on households in the City of Cape Town

Igel, Margret January 2024 (has links)
Amidst the backdrop of a for years lasting electricity crisis in South Africa, the study aims to examine the impact of prolonged urban energy infrastructure disruptions on residents on the household level. This investigation will aid a deeper understanding of the interdependencies between infrastructural services, households, and their socio-economic situations in urban landscapes. The study contributes to the literature of urban infrastructural disruptions and explores individual coping mechanisms and resilience strategies of the affected people.  For that, the research poses the following research question: How do urban dwellers react to, are limited by and cope with long-lasting and frequent urban electricity outages in the domestic realm in Cape Town. Drawing upon the theoretical frameworks of assemblage thinking, social practice theory and the concept of resilience, the thesis takes up a relational approach that emphasizes the complexity of the correlation between electricity networks and the life of urban residents. The researcher conducted seven qualitative in-depth interviews with residents of Cape Town regarding their individual experience with load shedding. The findings have shown that residents actively counteract power outages by assembling alternative energy appliances and the adjustment of routines. It was also visible that the respective socio-economic living situations affected the resilience of residents. Specifically, participants from less affluent backgrounds showed lower resilience in maintaining their usual daily social practices. The paper advocates for the importance of including especially the most vulnerable groups in counter initiatives in a way that would reduce the impact of power outages.
