Research on the dynamics of reward-based, goal-directed decision making has largely focused on simple choice, where participants decide among a set of unitary, mutually exclusive options. Recent work suggests that the deliberation process underlying simple choice can be understood in terms of evidence integration: Noisy evidence in favor of each option accrues over time, until the evidence in favor of one option is significantly greater than the rest. However, real-life decisions often involve not one, but several steps of action, requiring a consideration of cumulative rewards and a sensitivity to recursive decision structure. We present results from two experiments that leveraged techniques previously applied to simple choice to shed light on the deliberation process underlying multistep choice. We interpret the results from these experiments in terms of a new computational model, which extends the evidence accumulation perspective to multiple steps of action.

RESUMENLa teoría de Holland permite clasificar e identificar personas y ambientes conforme a la Tipología RIASEC. Utilizando una adaptación del Self-Directed Search (Holland, 1994) a adolescentes gallegos,Búsqueda Encaminada, 1998 (Eire, 1998) se obtuvieron códigos diferenciados correspondientes a cada una de las opciones académicas que se pueden dar en Bachillerato (Ciencias, Letras y Mixtas) que permiten establecer el grado de congruencia entre el Código Holland de un aspirante y la opción académica. Se discuten diversas implicaciones para orientadores y responsables de los servicios de orientación.ABSTRACTHolland’s theory allows to classify and to identify people and environmennts according to the RIASEC typology. Using an adaptation of the Self-Directed Search (Hollannd, 1994) to Galician adolescents —Búsqueda Encamiñada, 1998-BE-98 (Eire, 1998)— differentiated codes were obtained corresponding to each one of the academic options that there exist in High School (Sciences, Mixed and Letters) and that allow to establish the congruence degree between the Code Holland of an aspirantand the academic option. Different implications for the careers guidance and the orientation servicesare discussed.

How do children and adults differ in their search for rewards? We considered three different hypotheses that attribute developmental differences to (a) children’s increased random sampling, (b) more directed exploration toward uncertain options, or (c) narrower generalization. Using a search task in which noisy rewards were spatially correlated on a grid, we compared the ability of 55 younger children (ages 7 and 8 years), 55 older children (ages 9–11 years), and 50 adults (ages 19–55 years) to successfully generalize about unobserved outcomes and balance the exploration–exploitation dilemma. Our results show that children explore more eagerly than adults but obtain lower rewards. We built a predictive model of search to disentangle the unique contributions of the three hypotheses of developmental differences and found robust and recoverable parameter estimates indicating that children generalize less and rely on directed exploration more than adults. We did not, however, find reliable differences in terms of random sampling.

Abstract Alport syndrome (AS) is the most frequent inherited kidney disease after autosomal dominant polycystic kidney disease. It has three different patterns of inheritance—autosomal dominant, autosomal recessive and X-linked—which in part explains the wide spectrum of disease, ranging from isolated microhaematuria to end-stage renal disease early in life. The search for a treatment for AS is being pursued vigorously, not only because of the obvious unmet need but also because AS is a rare disease and any drug approved will have an orphan drug designation with its various benefits. Moreover, AS patients are quite young with very few comorbidities, which facilitates clinical trials. This review identifies the particularities of each pattern of inheritance but focuses mainly on new drugs or therapeutic targets for the disease. Most treatment-related investigations are directed not at the main abnormality in AS, namely collagen IV composition, but rather at the associated inflammation and fibrosis. Thus, AS may serve as a proof of concept for numerous drugs of potential value in many diseases that cause chronic kidney disease.

<b><i>Introduction:</i></b> Recent studies suggest that nonoperative management of appendicitis (NOMA) may be a reasonable option for managing uncomplicated acute appendicitis. We examined the Internet to see if patients are likely to find the information they need to make an informed decision between the 2 options. <b><i>Methods:</i></b> A list of 29 search terms was established by a focus group and then entered into Google, resulting in 49 unique webpages, each reviewed by 3 reviewers. Consensus was obtained for bias (surgery, NOMA, or balanced), webpage type, JAMA score, reading grade, and DISCERN score, a measure of quality of written information for patients. <b><i>Results:</i></b> Thirty of the 49 websites (61%) favored surgery, while 13 (27%) favored NOMA, and 6 sites (12%) provided balanced information. Twelve of 49 sites (24%) did not list NOMA as an option. The majority of patient-directed (11/12 = 92%) and physician-directed (7/9 = 78%) webpages favored surgery, whereas academic webpages presented a more balanced distribution. Academic and physician-directed webpages ranked higher than commercial and news webpages (median ranks 3 and 4 vs. 7.5 and 8). Only 8/49 sites (16%) mentioned that the presence of a fecalith predicts the failure of NOMA. Reading grades were almost all well above the recommended grade 8 level. <b><i>Conclusion:</i></b> Most of the webpages available on the Internet do not provide enough information, nor are they sufficiently understandable to allow most patients to make an informed decision about the current options for the management of acute appendicitis.

ObjectiveNudges are interventions that alter the way options are presented, enabling individuals to more easily select the best option. Health systems and researchers have tested nudges to shape clinician decision-making with the aim of improving healthcare service delivery. We aimed to systematically study the use and effectiveness of nudges designed to improve clinicians’ decisions in healthcare settings.DesignA systematic review was conducted to collect and consolidate results from studies testing nudges and to determine whether nudges directed at improving clinical decisions in healthcare settings across clinician types were effective. We systematically searched seven databases (EBSCO MegaFILE, EconLit, Embase, PsycINFO, PubMed, Scopus and Web of Science) and used a snowball sampling technique to identify peer-reviewed published studies available between 1 January 1984 and 22 April 2020. Eligible studies were critically appraised and narratively synthesised. We categorised nudges according to a taxonomy derived from the Nuffield Council on Bioethics. Included studies were appraised using the Cochrane Risk of Bias Assessment Tool.ResultsWe screened 3608 studies and 39 studies met our criteria. The majority of the studies (90%) were conducted in the USA and 36% were randomised controlled trials. The most commonly studied nudge intervention (46%) framed information for clinicians, often through peer comparison feedback. Nudges that guided clinical decisions through default options or by enabling choice were also frequently studied (31%). Information framing, default and enabling choice nudges showed promise, whereas the effectiveness of other nudge types was mixed. Given the inclusion of non-experimental designs, only a small portion of studies were at minimal risk of bias (33%) across all Cochrane criteria.ConclusionsNudges that frame information, change default options or enable choice are frequently studied and show promise in improving clinical decision-making. Future work should examine how nudges compare to non-nudge interventions (eg, policy interventions) in improving healthcare.

Background Acute limb ischemia represents a clinical emergency with eventual limb loss and life-threatening consequences. It is characterized by a sudden decrease in limb perfusion. Acute ischemia is defined as a duration of symptoms for less than 14 days. Aging of the population increases the prevalence of acute limb ischemia. The two principal etiologies are arterial embolism and in situ thrombosis of an atherosclerotic artery. Immediate diagnosis, accurate assessment and urgent intervention when needed are crucial to save the limb and to prevent a major amputation. Delay in diagnosis and therapy may lead to irreversible ischemic damage. Method To assess the current treatment options in acute limb ischemia, this review is based on a selective literature search in PubMed representing the current state of research. Results and Conclusion Patients with acute limb ischemia should receive immediate anticoagulation. Treatment depends on the classification based on the degree of ischemia and limb viability. Especially acute (< 14 days symptom duration) Rutherford Categories IIa and IIb with marginally and immediately threatened limbs require definitive therapeutic intervention and are salvageable, if promptly revascularized. The current literature suggests that open surgical revascularization is more time effective then catheter-directed thrombolysis. However, with the advent of thrombolytic delivery systems and mechanical thrombectomy devices, treatment time can be minimized and successful utilization in patients with Category IIb (Rutherford Classification for Acute Limb Ischemia) has been reported with promising limb-salvage and survival rates. Large randomized studies are still missing, and guidelines suggest choosing the method of revascularization depending on anatomic location, etiology, and local practice patterns, with the time to restore the blood flow being an important factor to consider.

The aim of the article was to overview the pathophysiology of the conventional outflow pathway, trabecular meshwork, and intraocular pressure and to discuss the options of future glaucoma treatment directed to improvement in aqueous outflow. The literature search in the Medline, Embase, and Cochrane databases from April to May 2012 was performed; a total of 47 articles analyzed. The diminished conventional pathway may be altered by several pathophysiological mechanisms like TM obstruction caused by transforming growth factor-β2, clastic nondeformable cells, macrophages leaking from hypermature cataract, iris pigment, lens capsular fragments after YAG-laser posterior capsulotomy, proteins and their subfragments. It is known that trabecular meshwork contraction reduces outflow, and the actomyosin system is directly linked to this mechanism. New glaucoma drugs are still under investigation, but it is already proven that agents such as latranculin-B are effective in improving aqueous drainage. Selective Rho-associated coiled coilforming protein kinase inhibitors have been shown to cause a significant improvement in outflow facility and may become a new option for glaucoma treatment. Caldesmon negatively regulates actin-myosin interactions and thus increases outflow. Stem cells may replace missing or nonfunctional trabecular meshwork cells and hopefully will bring a new treatment solution. Pathophysiological mechanisms regulating conventional aqueous humor outflow are still not fully understood and require further investigations. Future treatment decisions should be directed to a specific mechanism regulating an elevation in intraocular pressure.

Influenza A viruses (IAVs) infect humans and cause significant morbidity and mortality. Different treatment options have been developed; however, these were insufficient during recent IAV outbreaks. Here, we conducted a targeted chemical screen in human nonmalignant cells to validate known and search for novel host-directed antivirals. The screen validated saliphenylhalamide (SaliPhe) and identified two novel anti-IAV agents, obatoclax and gemcitabine. Further experiments demonstrated that Mcl-1 (target of obatoclax) provides a novel host target for IAV treatment. Moreover, we showed that obatoclax and SaliPhe inhibited IAV uptake and gemcitabine suppressed viral RNA transcription and replication. These compounds possess broad spectrum antiviral activity, although their antiviral efficacies were virus-, cell type-, and species-specific. Altogether, our results suggest that phase II obatoclax, investigational SaliPhe, and FDA/EMEA-approved gemcitabine represent potent antiviral agents.

In three directed search models with horizontal differentiation, this thesis characterizes the unique symmetric equilibrium for each model and studies the welfare property of equilibrium allocations. In Chapter 2, horizontal differentiation is modeled as buyers' valuations being independent. In equilibrium, sellers use a mixed strategy with the support consisting of a countable number of prices. Equilibrium price dispersion exists and equilibrium allocation is constrained inefficient due to price dispersion. Chapter 3 extends the model in Chapter 2 by allowing different degrees of horizontal differentiation. With large degrees of horizontal differentiation, sellers use a mixed strategy qualitatively similar to the equilibrium in Chapter 2. With small degrees of differentiation, sellers use a pure strategy. Chapter 4 extends the model in Chapter 2 by allowing differentiation to be endogenous. Initially buyers are equally uncertain about the characteristics of sellers' goods and no differentiation exists. Then sellers choose prices together with the amounts of information disclosed to buyers about the characteristics of sellers' goods. Information disclosure leads to differentiation after buyers receive the information. It is shown that a seller's profit by disclosing full information is higher than that by disclosing partial information. In equilibrium both sellers disclose full information and use a pricing strategy that is identical to the equilibrium in Chapter 2.

The current research represents the planning, design, implementation and evaluation of a user directed software clustering approach that utilizes Search Based Software Engineering (SBSE). The aim of this research is to examine if a user directed software clustering approach contributes to the quality of software clustering. Because of the explorative and constructive character this research project utilises the System Development Research Methodology. This research is enabled by the implementation of the Search Based Reverse Engineering (SBRE) component. The SBRE component features multiple similarity measurements and the inclusion of user constraints in the clustering process to create different implementation perspectives of the software system depending on the requirements and preferences of the stakeholders. These similarity measurements are based on software metrics, which measure different software-attributes. The SBRE component utilizes a greedy and tabu search algorithm for the identification of the cluster landscape of the analyzed software systems. The evaluation showed that a user controlled SBSE cluster approach is able to adapt to different user configurations and derive corresponding cluster landscapes from software systems. Different measures are introduced to control the cluster process. It has been shown how these measures contribute to the quality of the clustering. It is demonstrated that tabu search is applicable in the field of software clustering. Finally, it has been examined that a multiple metric approach allows adapting the clustering process to the requirements of the stakeholders and the design of the software system to optimize the clustering result.

This paper analyzes labor market frictions caused by heterogeneity among traders on the demand side (firms). Vacancy numbers per firm created at once can vary, and this heterogeneity affects the application probability of workers through the wage settings of firms, which determines the overall matching efficiency. I formulate a matching function that reflects vacancy concentration level in its efficiency parameter, and verify that concentration improves matching efficiency when its level is not so high, and such positive impacts can peak at an intermediate concentration level for the period of 1996-2005 in the Japanese regional labor markets (Chapter 1). In the following chapters, I examine whether this result fits the theoretical prediction. For this aim, I present a directed search model in which vacancy distribution among firms is asymmetric, in order to investigate matching efficiency and equilibrium wage levels. In Chapter 2, the model considers a monopsony market with two firms that have multiple vacancies each, while in Chapter 3 I extend the model to allow wage competition among more than two firms, using the framework of a dominant firm and competitive fringe firms. The models indicate that the derived equilibrium is generally not constrained efficient, and that matching efficiency can deteriorate with concentration, depending on the concentration level and worker-vacancy ratio. These results are consistent with my empirical findings of regional labor markets in Chapter 1. In the model of Chapter 3, the gap between the maximized output level in an efficient market and the level of the equilibrium is minimized in the case of intermediate concentration. Further, positive wage differentials are usually not obtained, but are obtained under certain market parameters.

Nous prenons l’approche d’annonce des salaires avec la recherche d’emploi à étudier trois problèmes dans le marché du travail. Le premier problème concerne l’arrêt de travail prématuré des travailleurs. Tel arrêt de travail prématuré crée des risques de chiffre d’affaires pour les entreprises, donc les entreprises veulent proposer des profils de salaire pour minimiser ces risques. Dans ce problème, l’asymétrie de l’information joue un rôle important. Nous adoptons une approche du mécanisme design et considérons les différents timings auxquels l’information privée est réalisée. Dans un papier de suivi, nous proposons une politique d’Age spécifique par laquelle cette inefficacité peut être atténuée, et étudions son implication sur le bien-être et la production globale. Dans le deuxième problème, nous revisitons l’analyse du bien-être de l’impact de la discrimination sur le choix des compétences sous une norme d’embauche multidimensionnelle le long des caractéristiques qui sont soit liées à la productivité soit indépendantes de la productivité. Nous montrons comment l’investissement de compétences stratégique entre le groupe favorise et discrimine se pose. Nous comparons également deux mécanismes de détermination des salaires (salaire annoncé et négocié) pour vérifier la robustesse de résultats. Dans le troisième problème, nous considérons dans quelle mesure l’allocation de chômage et le salaire minimum peuvent corriger les répartitions inefficaces découlant du pouvoir de marche des firmes. Notre contexte concerne les petits marchés ou le ratio travailleurs/firmes ne soit pas grand. L’imperfection de marche vient du fait qu’au marché du travail à petite échelle les firmes paient un niveau de salaire moins que le niveau compétitif. Nous procédons à partir d’un point de vue d’organisation industrielle, et proposons en se concentrant sur la mauvaise répartition d’emploi et de surplus lors de l’analyse de l’efficacité de l’instrument de la politique
We take the wage posting approach with search friction to study three issues in labor market. The first issue concerns the premature quitting of workers. Our framework is suitable for contexts such as disability shock, retirement, maternity leaves etc. Such premature quitting creates turnover risks for firms, hence the firms propose wage profiles to minimize or avoid it. In this issue, the asymmetric information plays an important role. We adopt an approach of mechanism design and consider different timings at which the private information is realized. In a follow-up paper, we propose an age-directed policy by which this inefficiency can be alleviated and study its implication on welfare and aggregate output. In the second issue, we revisit welfare analysis of impact of discrimination on skill choice under a multi-dimensional hiring norm along both productivity-related and -unrelated characteristics. We show how strategic skill investment between favored and discriminated group arise. We compare also two wage determination mechanisms (posted and bargained wage). In the third issue, we consider to which extent can the roles of unemployment benefit and minimum wage correct inefficient allocations arising from firms’ market power. Our context concerns small markets where the workers/firms ratio is not large. The market imperfection comes from the fact that in such a small market firms pay less than competitive level of wages. We proceed from an industrial organizational perspective and suggest focusing on both misallocation of labor and surplus when analyzing the effectiveness of the policy instrument

Learning behaviour of artificial agents is commonly studied in the framework of Reinforcement Learning. Reinforcement Learning gained increasing popularity in the past years. This is partially due to developments that enabled the possibility to employ complex function approximators, such as deep networks, in combination with the framework. Two of the core challenges in Reinforcement Learning are the correct assignment of credits over long periods of time and dealing with sparse rewards. In this thesis we propose a framework based on the notions of goals to tackle these problems. This work implements several components required to obtain a form of goal-directed behaviour, similar to how it is observed in human reasoning. This includes the representation of a goal space, learning how to set goals and finally how to reach them. The framework itself is build upon the options model, which is a common approach for representing temporally extended actions in Reinforcement Learning. All components of the proposed method can be implemented as deep networks and the complete system can be learned in an end-to-end fashion using standard optimization techniques. We evaluate the approachon a set of continuous control problems of increasing difficulty. We show, that we are able to solve a difficult gathering task, which poses a challenge to state-of-the-art Reinforcement Learning algorithms. The presented approach is furthermore able to scale to complex kinematic agents of the MuJoCo benchmark.
Inlärning av beteende för artificiella agenter studeras vanligen inom Reinforcement Learning.Reinforcement Learning har på senare tid fått ökad uppmärksamhet, detta berordelvis på utvecklingen som gjort det möjligt att använda komplexa funktionsapproximerare, såsom djupa nätverk, i kombination med Reinforcement Learning. Två av kärnutmaningarnainom reinforcement learning är credit assignment-problemet över långaperioder samt hantering av glesa belöningar. I denna uppsats föreslår vi ett ramverk baseratpå delvisa mål för att hantera dessa problem. Detta arbete undersöker de komponentersom krävs för att få en form av målinriktat beteende, som liknar det som observerasi mänskligt resonemang. Detta inkluderar representation av en målrymd, inlärningav målsättning, och till sist inlärning av beteende för att nå målen. Ramverket byggerpå options-modellen, som är ett gemensamt tillvägagångssätt för att representera temporaltutsträckta åtgärder inom Reinforcement Learning. Alla komponenter i den föreslagnametoden kan implementeras med djupa nätverk och det kompletta systemet kan tränasend-to-end med hjälp av vanliga optimeringstekniker. Vi utvärderar tillvägagångssättetpå en rad kontinuerliga kontrollproblem med varierande svårighetsgrad. Vi visar att vikan lösa en utmanande samlingsuppgift, som tidigare state-of-the-art algoritmer har uppvisatsvårigheter för att hitta lösningar. Den presenterade metoden kan vidare skalas upptill komplexa kinematiska agenter i MuJoCo-simuleringar.

In many turbomachinery applications a compressor is directly driven by a turbine; for turbocharger applications a centrifugal compressor is usually adopted which is generally driven by a radial flow turbine, although mixed flow or axial flow turbines are occasionally required. A non-dimensional design procedure is developed to provide the basic dimensions and blade angles of centrifugal compressor impellers, whilst accounting for the turbine conditions as assessed through the matching requirements. The design of the turbine is then considered further in Part B. The procedure can be applied for any desired compressor pressure ratio and target efficiency to develop an initial non-dimensional skeleton design. No other parameters are required from the initial specification and the design is developed non-dimensionally without recourse to empirical loss models and the associated uncertainties as the target efficiency must be specified. The procedure provides graphical information with respect to the impeller discharge conditions and inlet conditions from which the designer must select the most appropriate design. The screen graphics interface enables the designer to search across the design options; as this search is carried out numerical data are displayed and continuously up-dated to provide immediate information on which an infnrmed assessment can be based. In addition to the compressor design options which are provided the matching conditions for the drive turbine provides information, such as specific speed, non-dimensional mass flow rate and pressure ratio, relevant to the turbine design. Judgements with respect to the design options for the compressor can then be made with the consequences for the associated turbine design clearly in view. The non-dimensional design can be translated into an absolute design through the specification of the required mass flow rate and the inlet stagnation pressure and temperature.

Background: COVID-19 patients with chronic diseases and comorbidities are more susceptible to the severe form of the infection. Neurological symptoms are reported by some patients infected by the virus and research seeks the relationship between the virus and neurological diseases, such as Parkinson’s Disease (PD). Objectives: To understand how COVID-19 and its effects affect patients with PD. Methods: Integrative review with search on Google Scholar, Scielo, PubMed and Science Direct platforms through an online scenario, selected articles from the years 2020 and 2021. Results: SARS-CoV-2 frequently undergo mutations, causes damage and inflammation. There are reports of symptoms such as anosmia, ageusia and headache. Anosmia stands out for its relationship with one initial symptom of PD, hyposmia. As the majority of PD patients are elderly and have comorbidities, there is a higher risk of being infected. Some patients with PD infected by the virus report worsening in motor and non-motor symptoms and such worsening can occur due to systemic inflammation, stress and the measures to contain the pandemic. Conclusions: PD is not a risk factor for COVID-19, however patients may experience worsening symptoms due to comorbidities, old age and stress caused by the pandemic. Strategies that reduce stress are options for maintaining the health of patients with PD.

Introductory graduate level courses and upper division technical electives often present a student with his or her first research project. Time limitations of a course require a balance between open ended discovery, development of specialized technical knowledge, and teaching the mechanics of research methodology. The case study presented in this paper is an outline of two different strategies to introduce research to undergraduate students within the framework of a rotor dynamics laboratory. The laboratory had historically been designed to demonstrate machinery malfunctions in a series of short exercises. The laboratory was changed to have several introductory labs designed to prepare students for an extended self-directed research project that included literature searches, paper reviews, design of experiments, and presentation of research findings to the class. In one strategy the students were expected to practice discovery primarily through experimentation with specific, restricted goals. In the other strategy the students were given more flexibility defining the research question and in establishing priorities. Both projects had students design an experiment whose results were compared to mathematical simulations and each led to research that was presented at a conference. Although both were considered successful in terms of student learning and research outcomes, a balance biased toward experimentation and restricted student options for discovery actually led to broader research findings and more in-depth student research but with less student appreciation for and practice with the necessary preliminary stages of conducting research. The student learning experiences and methodologies for each scenario are presented and compared in this paper.

A comprehensive optimization study considering both system configurations and control strategies is needed for micro-grid energy systems. In order to address this need, this study provides an advanced optimization framework that extends existing energy system optimization studies in following four aspects: complete system optimization from scratch; comprehensive energy conversion equipment modeling for heating, cooling and power generations; modeling of cascaded configurations such as a cascaded absorption-compression refrigeration system and a cascaded organic Rankine cycle-direct heating system; and consideration of transient loads and weather profiles. The optimization framework aims to find optimum system configurations and control strategies for any given equipment options, and load- and weather-profiles in order to minimize life cycle cost. First, correlation based equipment models and cascaded system models were developed. Then the optimization framework was established using a genetic algorithm solver built in Matlab. The framework was presented through a case study on an oceanic container transportation application under transient loads and weather profiles. It was found that the optimized system was able to reduce life cycle cost by 40%. The optimized system is in favor of cascaded organic Exploring waste heat from the main engine that is used for main propulsion is the key to reduce life cycle cost. The developed optimization framework can be used for any applications as an efficient tool to search for novel energy system designs and their evaluations.

The Covid-19 crisis led multilateral and bilateral donors to revise their funding strategies to respond to the crisis and to adapt existing programming to the new context it created. This resulted in changes to overall allocations, with some countries increasing aid commitments and institutions like the World Bank scaling up lending to low- and middle-income countries while others have cut aid budgets due to low economic growth and demands on domestic resources at home. Changes in aid volumes and disbursal mechanisms are anticipated to have significant impacts on low- and middle-income countries’ abilities to cope with the crisis in the short term, and the targeting of these investments are likely to have a lingering effect on recoveries for years to come. Although aid makes up a small proportion of countries’ available finance to tackle the Covid-19 crisis, “other financing options such as foreign direct investment, workers’ remittances, and taxes – have fallen and are slow to recover” (Prizzon, 2021). Aid finance will therefore be critical to many countries’ short-term responses to Covid-19 and capacities to abate longer-term negative impacts on social and economic outcomes as countries begin to recover. This report gives a broad overview of trends in bilateral, multilateral, and private foundations’ funding strategies over the course of the pandemic to highlight observable shifts in practice. The review is based on a rapid search of funding announcements from a selection of bilateral donors, a selection of multilateral institutions, and overall trends reported by foundations. The report also includes evidence reported by secondary literature on finance for development over the course of the Covid-19 crisis.
