This cas...In Ireland, in 2008, pig feed manufactured from recycled human food became contaminated with dioxin and this led to a global recall of all Irish pork products produced from 1st September to 6th December 2008. This case study illustrates several points a) the food chain is only as secure as its weakest link, b) due to the complexity of the modern food chain, once pork is processed, precise traceability to a particular farm of origin is impossible, c) even with a single food agency, overseeing the policing of the food chain, things can go wrong, d) it demonstrated the benefits of having credible consumer protection agencies to undertake scientific risk assessment and communicate with the public, e) if risk management decisions are taken quickly, and communicated in an open and transparent manner to the public, adverse human health effects can be avoided and consumer confidence can maintained, f) in the EU the legal limit for dioxins in pork fat is 1 picogram per gram (10-12 ) and attempting to communicate the risks associated with this level of contamination plus the concepts of bioaccumulation and body burden and the need for continued exposure to result in adverse health effects is extremely challenging, g) there was a major economic impact and damage to the country's reputation as a food exporter and finally h) it illustrates that prevention is better that crisis management. Other countries can learn lessons from this incident that may prevent similar occurrences in their jurisdictions.展开更多

Norms regulate the actions of human actors based on the dynamics of the environment in which they are situated. This dynamics results from both environment evolution and actors' actions. Our objective is to situate norms in the environment in order to provide a context-aware crisis regulation. However, this coupling must be a loose one to keep both levels independent and easyto-change in order to face the complex and changing crisis situations. To that aim, we introduce a constitutive level between environmental and normative states providing a loose coupling of normative regulation with environment evolution. Norms are thus no more referring to environmental facts but to status functions, i.e., the institutional interpretation of environmental facts through constitutive rules. We present how this declarative and distinct SAI modelling succeeds in managing the crisis with a context-aware crisis regulation.展开更多

文摘Corona Virus Disease-2019(COVID-19)was reported at first in Wuhan city,China by December 2019.World Health Organization(WHO)declared COVID-19 as a pandemic i.e.,global health crisis onMarch 11,2020.The outbreak of COVID-19 pandemic and subsequent lockdowns to curb the spread,not only affected the economic status of a number of countries,but it also resulted in increased levels of Depression,Anxiety,and Stress(DAS)among people.Therefore,there is a need exists to comprehend the relationship among psycho-social factors in a country that is hypothetically affected by high levels of stress and fear;with tremendously-limitingmeasures of social distancing and lockdown in force;and with high rates of new cases and mortalities.With this motivation,the current study aims at investigating theDAS levels among college students during COVID-19 lockdown since they are identified as a highly-susceptible population.The current study proposes to develop Intelligent Feature Subset Selection withMachine Learning-based DAS predictive(IFSSML-DAS)model.The presented IFSSML-DAS model involves data preprocessing,Feature Subset Selection(FSS),classification,and parameter tuning.Besides,IFSSML-DAS model uses Group Gray Wolf Optimization based FSS(GGWO-FSS)technique to reduce the curse of dimensionality.In addition,Beetle Swarm Optimization based Least Square Support Vector Machine(BSO-LSSVM)model is also employed for classification in which the weight and bias parameters of the LSSVM model are optimally adjusted using BSO algorithm.The performance of the proposed IFSSML-DAS model was tested using a benchmark DASS-21 dataset and the results were investigated under different measures.The outcome of the study suggests the development of specialized programs to handleDAS among population so as to overcome COVID-19 crisis.
文摘After more than 40 years of development,China's travel agency industry has grown rapidly,but the situation of scattered,small,weak and poor has not fundamentally changed.The unexpected the public health event crisis of COVID-19 in 2020 has brought great influence on China's travel agency industry,which makes China's travel agency industry face double challenges at home and abroad,but also breeds opportunities for development.In the face of the crisis,China's travel agency industry has responded to it,trying to restore confidence and revive the economy.This paper puts forward some idea from the aspects of crisis management,marketing and product development,including the establishment and implementation of the normalized tourism public crisis response mechanism;the reconstruction of the tourism image of the travel agency industry;the strengthening of marketing,with special attention to new media marketing;the emphasis on natural education,and the enhancement of the upgrading of tourism products.
文摘This case study presents the dilemma faced by a French university with Christian identity regarding a students’request to officially approve a club for the LGBTQ+community:which would be the most prudent response considering all matters involved?The case is disguised:it combines elements taken from very similar cases impacting today more than a few Catholic universities around the globe.Part A describes this university:history,principles and values,academic and financial information,relations with its stakeholders,etc.This part also describes its religious context and some relevant statistics regarding the LGTBQ+community.Finally,a series of opinions regarding the issue and how to answer the students’request presented in the form of an open discussion at the university’s steering committee provides different arguments in favor or against the approval.Part B offers some guidelines useful to take a prudent response considering all matters involved:legal,ethical,governance,and communicative.These guidelines are divided in three chapters:what should be the framework for such a discussion,strategic recommendations,and practical suggestions.Their aim is to provide a sort of a blueprint for university heads and administrators,to design a tailor-made response fitting the identity and stakeholders’map of their own university.
文摘Pre-crisis management involves the optimal selection of relief and rescue centers to minimize vulnerability.Iran is particularly vulnerable due to its location on the Alpine-Himalaya seismic belt,resulting in an average death rate six times higher than the global average during earthquakes.Therefore,selecting appropriate relief and rescue centers is crucial to Iran’s disaster preparedness.When selecting the placement of rescue centers,accessibility and the appropriateness of the land should be taken into account as well as the distance from high-risk areas.The location of these centers does not require any particular combinations.To address this issue,a study was conducted utilizing GIS,artificial neural networks,fuzzy logic,and mathematical models to determine the optimal placement based on 12 indicators within two clusters:natural and human.To examine the information layers of the initial stage,a spatial data repository concerning the variables impacting the placement of these centers was established using ARCGIS.Using functions and algorithms such as Fuzzy Logic in IDRISI,TOPSIS,and VIKOR software,the layers were assessed for weightage before being overlaid.The study’s analysis of the models used revealed that the positioning priority limits of the areas differed across all four models.Notably,the areas with high desirability varied to a greater extent:the fuzzy model varied by 9.3%,neural network by 12.4%,VIKOR by 4.5%,and TOPSIS by 16.2%.The variance in results can be attributed to the differing levels of risk acceptance and non-acceptance in each model.Additionally,the study yielded other significant findings such as the correlation between study area size and model accuracy.Specifically,smaller study areas exhibited higher model accuracy.The research also demonstrated that both fuzzy and VIKOR models achieved greater accuracy.As a result,employing these models in crisis management planning,particularly in pre-crisis management for identifying rescue center locations,would be highly advantageous and increase the precision of these endeavors.
文摘During a period of profound adjustments to the international power structure,China-US financial competition may intensify and lead to a crisis for the international financial system and even the international power system.The China-US financial relationship is structured in mainly four dimensions:the international monetary system,bilateral financial exchanges,the international financial system and the construction of international financial and/or economic concepts.Management of this competition relationship is thereby four-pronged:managing the relationship between the RMB and the US dollar in the international monetary system,the China-US bilateral creditor-debtor relationship,the indirect China-US relationship in global financial governance organizations and normative frameworks,and the divergence of both countries in regard to their economic ideologies.In particular,to stabilize the international monetary system,China should postpone the strategic confrontation between the RMB and the US dollar,strengthening their complementarity and cooperation based on market choice and their monetary function.Meanwhile,China should be prudent as a creditor to the United States,neither coerced by its over-reliance on American financial markets,nor tempted to weaponize the US debt by dumping US bonds.Also,before aiming for systematic reforms,China should first aim to become a stakeholder in the current global financial governance system by comprehensively accepting and becoming deeply integrated into it.Finally,China should avoid the economic competition model between China and the United States,and should instead apply the“Chinese Approach”to better facilitate solutions to international problems.These approaches to crisis management aim to help China endure this turbulent period of the international power system with more prudent strategies and policies,and to maintain a relatively stable international financial and economic environment for the sustained rise of its economy and for the rejuvenation of the Chinese nation.

文摘Nowadays,resilience has become an indispensable term in several aspects and areas of research and life.Reaching consensus on what actually constitutes"resilience,""community,"and"community resilience"is still a task that guarantees a vivid exchange of opinions,sometimes escalating into debates,both in the scientific community and among practitioners.Figuring out how to practically apply resilience principles goes even a step further.This study attempts to circumvent the need for a universal agreement on the definition of"community resilience,"which may still be immature,if not impossible,at this time.We accomplish this by proposing a practical methodological approach with concrete methods on how to agree and implement commonly accepted community resilience principles in the context of technology development and pilot testing for disaster management.The proposed approach was developed,tested,and validated in the context of the Horizon 2020 EU-funded project Search and Rescue.Major aspects of the approach,along with considerations for further improvement and adaptation in different contexts,are addressed in the article.

文摘Public emergencies exert a significant impact on the mental health of the people,while psychological crisis intervention can efficiently improve the level of the mental health. The existing psychological crisis intervention in China has weakness in organization system,budget input,human resources,social cognition,and other aspects. The psychological crisis intervention work in the future can be performed by actively perfecting the organization management system of psychological crisis intervention,increasing the budget input,strengthening the construction of psychological intervention teams,improving the level of social cognition,and so on.
