Application of Big Data Analytics in Agriculture Supply Chain Management

Mangalam Ananthapadmanabhan, Sankara Narayanan 01 June 2019 (has links) (PDF)
The increasing trend in frequency of natural disasters in tandem with globalization of business makes the agricultural supply chain significantly vulnerable to disruption. This thesis presents a pragmatic approach for creating a Business Continuity Model that can notify supply chain planners when there is an increase in risk of agriculture supply chain disruption due to natural disasters. The methodology presented in this thesis applied big data analytics and machine learning algorithms along with agriculture product related exponential decay function to create a regionalized composite risk score, that incorporated both direct and indirect risk associated with the Agriculture Fresh Supply Chain. This model will aid supply chain planners in creating and implementing contingency plans, at the right time per given food production location. This risk score can help food manufacturing organizations to have a Business Continuity Plan that alleviate agriculture business supply chain interruptions. An example application of this model is illustrated with a melon packaging industry.

Hur påverkas läkemedelsföretags aktiepriser vid en naturkatastrof? : En eventstudie om orkanen Ians påverkan på de största läkemedelsföretagens aktiepriser i USA

Bokfors, Petrus, Köyluoglu, Tunahan January 2023 (has links)
Klimatförändringar och global uppvärmning kan ses som bidragande faktorer kring hur naturkatastrofer blir allt mer frekventa. Naturkatastrofer kan skapa obalans mellan utbud och efterfrågan och ha en inverkan på aktiemarknaden. Syftet med denna studie är att undersöka naturkatastrofers, närmare bestämt orkanen Ians, inverkan på läkemedelsföretags aktiepriser. Studien antar en kvantitativ ansats och hämtar sin empiri från databasen Factiva. Genom att använda teorierna effektiva marknadshypotesen (EMH) samt behavioral finance studeras 61 stycken av de största börsnoterade läkemedelsföretagen i USA med en eventstudie. Läkemedelsföretagen delas in i storleksbaserade portföljer inom de tre läkemedelsföretags-kategorierna “Medical Equipment/Supplies”, “Pharmaceuticals” och “Healthcare Provision” där de undersöks och jämförs. Studien har även inkluderat en branschspecifik variabel i form av godkända läkemedelsprodukter för “Pharmaceuticals”. Läkemedelsföretagen observeras fem dagar före eventdagen, under själva eventdagen (28 september), och fem dagar efter eventdagen. Enligt resultaten går det att tyda att endast ett signifikant samband av elva hypotesprövningar kunde observeras, vilket var för mindre stora läkemedelsföretag inom kategorin Healthcare Provision med en negativ CAAR på -4,15 procent. Tidigare forskning visar blandade reaktioner hos branscher till följd av naturkatastrofer, däribland fann Malik och Faff (2022) ett liknande negativt signifikant samband för små läkemedelsföretag inom Healthcare Provision. Resultatet indikerar att mindre stora läkemedelsföretag inte är lika motståndskraftiga vid naturkatastrofer som stora läkemedelsföretag. Vidare indikerar även resultatet att aktieprisförändringarna i eventstudien agerat likartat med aktieindexet S&P 500 och det är därmed troligt att studiens resultat till stor del beror på effekterna av S&P 500. / Climate change and global warming can be seen as contributing factors to the increasing frequency of natural disasters. Natural disasters can create imbalances in supply and demand and have an impact on the stock market. The purpose of this study is to investigate the impact of natural disasters, specifically Hurricane Ian, on pharmaceutical company stock prices. The study adopts a quantitative approach and draws its empirical data from the Factiva database. Using the theories of the Efficient Market Hypothesis (EMH) and behavioral finance, 61 of the largest publicly traded pharmaceutical companies in the United States are studied using an event study. The pharmaceutical companies are divided into size-based portfolios within the three pharmaceutical company categories: "Medical Equipment/Supplies", "Pharmaceuticals", and "Healthcare Provision", where they are examined and compared. The study also includes an industry-specific variable in the form of approved pharmaceutical products for the "Pharmaceuticals" category. The pharmaceutical companies are observed five days before the event day, on the event day itself (September 28), and five days after the event day. According to the results, only one significant relationship out of eleven hypothesis tests could be observed, which was for smaller Healthcare Provision companies with a negative CAAR of -4.15 percent. Previous research shows mixed reactions among industries following natural disasters, including Malik and Faff (2022) finding a similar negative significant relationship for small Healthcare Provision pharmaceutical companies. The result indicates that smaller Healthcare Provision companies are not as resilient to natural disasters as larger pharmaceutical companies. Furthermore, the result also suggests that the stock price changes in the event study have acted similarly to the S&P 500 stock index, indicating that the study's results are largely influenced by the effects of the S&P 500.

Le Verglas, analyse et réemploi des images d’une catastrophe

Vignaud, Pierre 02 1900 (has links)
Mémoire en recherche-création. / À partir d’archives diffusées sur YouTube, ce mémoire s’intéresse à la catastrophe naturelle du Verglas de 1998. Les vidéos sont l’occasion d’une réflexion sur l’esthétique des images d’information journalistique de catastrophes naturelles, sur le support VHS qui a permis leur premier enregistrement (la création d’une mémoire), et sur la télévision, médium qui les a d’abord diffusées. Conjointement à l’analyse de ces images est exposée la démarche de leur réemploi qui a mené à la réalisation d’un essai filmique. Le réemploi s’est notamment effectué en altérant des archives avec des magnétoscopes, fruits de la technologie de l’époque, qui avaient permis d’enregistrer les images télévisées. Avec ce geste de réemploi sont apparues des perspectives esthétiques qui permettent de voir la catastrophe autrement. D’autre part, ce projet a conduit l’auteur, muni d’une caméra VHS, à aller sur les lieux de l’événement, filmer les pylônes reconstruits, mais aussi au-delà, à la Baie James. Ce travail de recherche-création procède d’une méthode non systématique mais qui suit des chemins ouverts par les archives, par les technologies rencontrées ou par les images créées. Il envisage la question fondamentale que posent les catastrophes naturelles : celle du rapport qu’entretient l’homme avec la nature. / From archives released on YouTube, this thesis aims to explore the natural disaster of Ice Storm of 1998. The videos offer an opportunity to reflect on the aesthetic images of journalistic information on natural disasters, but also on the VHS medium that allowed their first recording (the creation of a memory), as well as on television, the medium that first distributed them. Alongside the analysis of these images, this thesis presents the process for reusing them, which led to the production of a film essay. Archives were altered thanks to video recorders, the technological advancement of the time, which allowed the recording of televised images. With reuse, came aesthetic perspectives that allow us to see the disaster differently. On the other hand, this project led the author, equipped with a VHS camera, to go to the scene of the event, to film the reconstructed pylons, but also to go beyond, to James Bay. This research-creation work was developed through a non-systematic method, rather following the paths opened up by the archives, technologies encountered or images created. It considers the fundamental question posed by natural disasters : that of the relationship between man and nature.

Centralized Disaster Management Collaboration in Turkey

Hermansson, Helena January 2017 (has links)
Following unprecedented earthquakes in 1999, highly centralized Turkey initiated reforms that aimed to improve disaster management collaboration and to empower local authorities. In 2011, two earthquakes hit the country anew affecting the city of Van and town of Erciş in Turkey’s southeast. In attempts to reduce disaster risk, global disaster risk reduction frameworks and disaster scholars and practitioners advocate collaborative and decentralized disaster management strategies. This thesis investigates how such strategies are received in a centralized and hierarchical national political-administrative system that largely is the anti-thesis of the prescribed solutions. More specifically, this research investigates the barriers and prerequisites for disaster management collaboration between both public and civil society actors in Turkey (during preparedness, response, and recovery) as well as how Turkey’s political-administrative system affects disaster management collaboration and its outcomes. The challenges to decentralization of disaster management are also investigated. Based on forty-four interviews with actors ranging from national to village level and NGOs, the findings suggest that the political-administrative system can alter the relative importance, validity, and applicability of previously established enabling or constraining conditions for collaboration. This may in turn challenge previous theoretical assumptions regarding collaboration. By adopting a mode of collaboration that fit the wider political-administrative system, collaborative disaster management progress was achieved in Turkey’s national level activities. Although there were exceptions, collaboration spanning sectors and/or administrative levels were generally less forthcoming, partly due to the disjoint character of the political-administrative system. Political divergence between local and central actors made central-local collaboration difficult but these barriers were partly trumped by other prerequisites enabling collaboration like interdependence and pre-existing relations. The findings suggest that the specific attributes of disasters may both help and hinder disaster management collaboration. Such collaboration generally improved disaster response. The findings also indicate that the decentralization attempts may have been premature as the conditions for ensuring a functional decentralization of disaster management are presently lacking. Decentralization attempts are commonly suggested to increase local capacity and local participation but the findings of this dissertation suggest that in Turkey, these commodities may currently have better chances of being increased by refraining from decentralization.

Due to the low investment in urban planning and disaster forecast, the public sector response time of cities, state and federation is longer than the expected by the population that need to live with tragedy imminent risk. Financial resources restriction of small cities together with low investment in ICT solutions to improve the quality of the services delivered to the population. However, the financial impact after tragedy is significant. Considering the expenses increase with disasters impacts and the disaster planning financial investment resources restriction context, the use of open standards in network components (sensors, hubs, proxies, database systems), with cloud data processing, allows solution design and implementation to leverage the natural disasters management planning in small cities with effectiveness and cost significantly lower than the currently available solutions.

Finansmarknadens reaktioner på naturkatastrofer förorsakade av enskilda bolag : En eventstudie av katastrofen i den Mexikanska golfen 2010

Moya, Juan, Östlund, Johannes January 2010 (has links)
Bakgrund: Den 20:e april 2010 inträffade en explosion på BP:s oljeplattform Deepwater Horizon i Mexikanska Golfen. Explosionen uppstod på grund av metangas som under högt tryck expanderade på plattformen och sedan antändes. Detta ledde senare till att oljeplattformen sjönk och ett stort okontrollerat oljeläckage uppstod på cirka 1500 meters djup.          Att explosionen i den mexikanska golfen har påverkat BP negativt och varit mycket kostsamt för företaget är uppenbart, börskursen hade som mest sjunkit med cirka 60 procent. Det kan vara intressant att undersöka huruvida denna katastrof, utlöst av en enskild aktör, också har spridit sig över till andra aktörer i Olja &amp; Gas sektorn. Syfte: Syftet med denna C-uppsats är att undersöka huruvida BP:s katastrof i den Mexikanska golfen har påverkat andra aktörer i samma sektor (Olja &amp; Gas sektorn). Metod: Sekundärdata presenteras som en kvantitativ ansats i form av siffror och för att kunna dra slutsatserna använder vi oss av en deduktiv ansats.I denna studie tillämpas en metodikteknik i form av en eventstudie, där beräkningar av den abnorma och förväntade avkastningen baseras på marknadsmodellen. Vidare har två hypoteser testats, där syftet med Hypotes I är att pröva huruvida information om händelsen i den Mexikanska Golfen påverkar andra företag i samma sektor som BP. Syftet med Hypotes II är att testa samma företag under samma period som Hypotes I, men undersöker förändring i tradingvolymerna istället för i aktiekurserna. Teori: Effektiva Marknadshypotesen, Random Walk och Flockbeteende Slutsatser: Dessa båda undersökningar d.v.s. Hypotes I och Hypotes II pekar starkt på slutsatsen att eventet har haft inverkat på övriga bolag i sektorn. Vi kunde vid en jämförelse med tidigare studier som genomförts på andra katastrofer, konstatera att skeendet har både likheter och skillnader. / Background: On the 20th April 2010, the BP oil platform Deepwater Horizon, situated in the Mexican Gulf, exploded. The explosion was caused by methanol gas that, under high pressure expanded and thereafter ignited. The platform submerged and caused a severe and uncontrollable oil leakage at 1500 meters depth.It is obvious that the explosion in the Mexican Gulf has impacted BP in a negative manner and cause BP large financial loss, the company shares had at its worst point depreciated by 60 percent. It may be of interest to investigate whether this catastrophe, caused by one independent party, also have affected other companies within the Oil and Gas industry. Purpose: The aim of this assignment is to investigate whether BP’s catastrophe in the Mexican Gulf has affected other companies within the same industry. (Oil and Gas) Methodology: Secondary data is presented as a quantitative approach in the shape of values and we use a deductive approach in order to draw the conclusions.The methodology used in this study is event study, in which calculation of the abnormal and expected revenue are based on the market model. We will test two types of hypothesis, where the aim of Hypothesis I is to test in which way information about the event in the Mexican Gulf affects other companies in the same industry as BP. The aim of Hypothesis II is to test the same companies during the same period as Hypothesis I, but with a focus on analyzing trading volume instead of the stock market value. Theory: Efficient Market Hypothesis, Random Walk and Herd Behavior Conclusion: Both investigations, i.e. Hypothesis I and Hypothesis II indicate that the event has had an impact on other companies in the same industry. We could, in a comparative analysis with earlier studies, based on other catastrophes, conclude that the event demonstrates similarities as well as differences.

Krizové řízení výrobní plastikářské společnosti / Risk management of the production plastic company

MALÝ, Jan January 2009 (has links)
Nowadays more and more new chemicals are used for numerous technologies and ap-plications by diverse chemical, plastic processing and other companies. Are all such companies fit to manage and solve chemical breakdowns, extraordinary events and critical or even emergency situations? Surely a very interesting question. Therefore I have decided for my study to analyse a crisis management system of a plastic processing company located in the City of Liban, region Hradec Kralove. Current status of coordination of the integrated rescue system (hereinafter referred to as the "IZS"). Classification of hazardous chemical substances. Simulating of extraordinary events using the software tool TerEx with respect to diverse chemicals operated by and within the Company. Evaluation of selected chemical substances according to hazards induced. Risk analysis, Analysis of occurrance of extraordinary events like e. g. windstorm, fire or escape of dangerous chemical substance, disconnecting of supply medium (heat, energy, power, water) and their treatment. Methods of actions at threat of bomb attack. Determination whether the IZS coordination including of the documentation elaborated are satisfactory with respect to the plastic processing company as well as with respect to successful mastering of extraordinary and emergency situations. Crisis management of business economics and economic distress.
