The purpose of this paper is to discuss the impacts of the communication time-delays to the distributed containment control of the second-order multi-agent systems with directed topology.

A basic theoretical analysis is first carried out for the containment control of the second-order multi-agent systems under directed topology without communication time-delay and a sufficient condition is proposed for the achievement of containment control. Based on the above result and frequency-domain analysis method, a sufficient condition is also derived for the achievement of containment control of the second-order multi-agent systems under directed topology with communication time-delays. Finally, simulation results are presented to support the effectiveness of the theoretical results.

For the achievement of containment control of the second-order multi-agent systems under directed topology with communication time-delay, the control gain in the control protocols is completely dependent on the communication topology structure and the maximum of time-delay in the control protocols is dependent on the given control gain and communication topology structure.

The paper investigates the containment control of the second-order multi-agent systems under directed topology with communication time-delays and presents a sufficient conditions for the achievement of containment control. The results and approach proposed in the paper may benefit interesting researchers.

Leaders at higher education institutions (HEIs) in the USA experience substantial pressure to contain costs while advancing their educational missions. The purpose of this paper is to explore the association between publicly stated academic cost-containment objectives found in HEI’s strategic plans and mission statements, which help to unify stakeholders and link strategy to an organization’s purpose.

This paper analyzes mission statements and strategic plans of 57 small, private HEIs in the Northeastern USA. HEIs in this sample published strategic plans with an explicit cost-containment goal. Mission statements were analyzed for readability. Thematic analysis was conducted using the balanced scorecard approach. Associations between a stated academic cost containment goal and mission statement themes are presented using logistic regression.

Mission statements of HEIs focused on academic cost containment are wordier and more varied. They tend not to mention “liberal arts,” a potential signal of a high-quality, high-cost school; less selective schools may be more likely to emphasize academic cost cutting.

This paper contributes to the literature demonstrating mission statements’ role in goal setting. Further, it considers college costs from college administrators’ perspectives. Given the small sample size, future work should expand the sample and use case studies to explore how mission shapes or constrains strategic objectives.

This is the first paper using qualitative and quantitative analysis to explore the association between the mission statements of small HEIs and academic cost containment goals in strategic plans, documents intended to support differentiation in a crowded market.

This study aims to explore the efficacy of government policy directions in mitigating the effects of the COVID-19 pandemic by employing a panel of 22 countries throughout the 2020-second quarter of 2022.

The panel autoregressive distributed lag (ARDL) model is employed to examine this phenomenon and to investigate the long-run effects of government policy decisions on infection and mortality rates from the pandemic.

The study reveals the following key findings: (1) Income support and debt relief facilities and stringent standards of governments are associated with reduced infection and death rates. (2) The response of governments has resulted in decreased mortality rates while simultaneously leading to an unexpected increase in infection rates. (3) Containment and healthcare practices have led to a decrease in infection rates but an increase in mortality rates, presenting another counterintuitive outcome. Despite the expectation that robust government responses would decrease infection rates and that healthcare containment practices would reduce mortality, these results highlight a lack of health equity and the challenge of achieving high vaccination rates across countries.

To effectively combat the spread of COVID-19, it is crucial to implement containment health practices in conjunction with tracing and individual-level quarantine. Simply implementing containment health measures without these interconnected strategies would be ineffective. Therefore, policy implications derived from containment health measures should be accompanied by targeted, aggressive, and rapid containment strategies aimed at significantly reducing the number of individuals infected with COVID-19.

This study concludes by suggesting the importance of implementing economic support in terms of income, and debt relief has played a crucial role in mitigating the spread of COVID-19 infections and reducing fatality rates.

To effectively combat the spread of COVID-19, it is crucial to implement containment health practices in conjunction with tracing and individual-level quarantine. Simply implementing containment health measures without these interconnected strategies would be ineffective. Therefore, policy implications derived from containment health measures should be accompanied by targeted, aggressive, and rapid containment strategies aimed at significantly reducing the number of individuals infected with COVID-19.

This research makes a unique contribution to the existing literature by investigating the impact of government responses on reducing COVID-19 infections and fatalities, specifically focusing on the period before COVID-19 vaccinations became available.

The purpose of this paper is to integrate psychological dimension, social dimension, and environmental dimension – six internet psychological characteristics (dissociative anonymity, invisibility, asynchronicity, solipsistic introjection, dissociative imagination, and minimization of status and authority), deindividuation, social influence (subjective norm and descriptive norm), and containment theory (inner containment and outer containment) – to propose an innovative model which can make up for deficiencies in previous studies of the toxic online disinhibition effect.

On the basis of 530 valid responses collected from an online survey questionnaire, partial least squares technology was used to examine the research model.

The result shows that dissociative anonymity has a significant impact on deindividuation and toxic disinhibition. In addition, asynchronicity and dissociative imagination have a direct effect on toxic disinhibition. Besides, in social influence, the authors found that subjective norm is a stronger predictor of toxic disinhibition than descriptive norm. Moreover, in containment theory, the result shows that inner containment can effectively reduce toxic disinhibition but not outer containment.

This study can provide academics and practical side empirical evidence as to what factor would cause toxic disinhibition and provides an innovative view regarding the relationship between social influence and containment theory on toxic disinhibition.

Following the COVID-19 outbreak, various economies imposed different financial interventions as part of initiatives to cushion their stock markets from deteriorating performance. Our article examines the effectiveness of these interventions in protecting stock markets during the pandemic.

The authors employ Panel Vector Autoregression to model the magnitude and timing of shocks from COVID-19 to stock markets. The fixed effects regression is then utilized to assess the role of financial interventions in protecting stock markets during COVID-19. The study uses daily stock index returns as well COVID-19 containment measures stringency index data from 39 countries ranging from 2nd January 2020 to 30th September 2021.

Our findings firstly reveal a significant positive stock market reaction to country-level containment measures stringency but only during the first wave of COVID-19. We secondly show that stock market functioning interventions that include short selling bans and circuit breakers amplify the positive effects of COVID-19 containment measures stringency on stock market performance.

The authors stress the need for policymakers and regulators to timely intervene in protecting economies and stock markets during crises such as COVID-19 in order to reduce panic among investors. Moreover, investors should adjust their portfolios by investing in stocks from countries that have proper financial market interventions in place.

Despite growing body of literature on COVID-19 and stock market performance, there is limited evidence on the role of financial sector interventions to cushion stock markets during tumultuous conditions caused by the pandemic.

Does internal integration extend to business continuity and to managing supply chain disruptions (SCDs)? Despite the voluminous literature on supply chain integration, evidence on its effectiveness on risk management and disruption response is scant. The purpose of this paper is to assess the effectiveness of business continuity management (BCM) and of supply chain involvement in BCM (SCiBCM) on reputational and operational damage containment in the face of SCDs.

This study draws on Simons’ Levers of Control framework to explain how the involvement of supply chain in BCM affects firm capabilities in containing damages caused by major SCDs. The authors develop and test hypotheses by analyzing large-scale questionnaire responses from 448 European companies.

Results of the data analysis suggest that BCM improves reputational damage containment, whereas SCiBCM improves operational damage containment. The findings also show that the significant effects of BCM and SCiBCM on reputational and operational damage containment, respectively, were amplified for the firms facing higher supply chain vulnerability. Post-hoc analysis further reveals the complementarity effect between BCM and SCiBCM for the companies exposed to high supply chain vulnerability.

Evidence on the effects of BCM and its internal integration on performance is limited. This study offers empirical evidence on the topic. Also, while supply chain integration can improve information sharing and coordination, some may not fully recognize its potential benefits in addressing SCDs. This study theoretically and empirically demonstrates the role played by internal integration, in the form of SCiBCM, in improving organizational damage containment efforts.

Although COVID-19 has caused a global slowdown, the magnitude of GDP losses appears to vary across countries. This study considers the question: could digital finance help to mitigate the adverse impact of COVID-19 on GDP? Countries with higher levels of digital financial inclusion are found to experience less fall in GDP, whereas countries relying more on cash transactions experience a greater GDP decline. These results suggest that digital financial inclusion might play a key role in mitigating the adverse impact of COVID-19 on GDP.

The study focuses on (1) the success of three strategies employed during the pandemic – two “persevering” strategies, curbside pickup and return window extension and one innovative strategy, virtual try-on technology and (2) whether the strategies are likely to be successful in the post-pandemic world.

The authors utilize a panel dataset containing 17 department store chains in the US The panel includes weekly sales by the retailers at the city level from 2018 to 2021, encompassing both a pre-COVID-19 period and a period during the pandemic. A two-way fixed effects model, including retailer-city fixed effects and year-week fixed effects, is used to estimate department store sales.

The authors find that the two persevering strategies offset the negative impact of government-imposed containment and health measures on sales performance. On the other hand, the innovative strategy is more effective with a low level of containment and health measures, leading to our observation that virtual try-on may be more sustainable than the other two strategies in a post-pandemic environment.

This paper makes the following contributions: First, the authors contribute to the literature on strategies that may be used to respond to crises. Second, the authors contribute to the retail management literature, assessing the impact of the three retail strategies on department store sales. Finally, the authors compare the impact on sales of the two persevering strategies to the innovative strategy and conclude that a mix of these types of strategies may be most effective at generating short-term sales during a crisis and longer-term sales post crisis.

A study of property developers in Singapore showed that their crisis management capabilities are influenced by their size and opinion. Developers generally concentrate on preparing formal procedures to deal with crises pertaining to breakdowns. Explicit procedures to deal with crises in the areas of psychopathology and human resource factors were often found lacking. Few developers implement damage containment mechanisms for external information attack and human resource factors, much less effect the same for psychopathic attacks. Developers have identified the key personnel, tasks, services and products necessary to conduct business operations. However, the ability of developers to recover from crisis situations is hampered by the lack of alternative sites for their critical operations and backups to crucial business function. Although it is the requirement of the developers to discuss the lessons learned for those involved in accidents and crisis, the ability to learn from past mistakes is often impeded by the assignment of blame.

Chief executive officers (CEOs) at America’s top 100 commercial banks, savings institutions and credit unions were surveyed to determine the importance of cost containment and customer retention practices. The study explores differences that exist among the three types of financial institutions. The results of the survey indicate that commercial bank CEOs rate themselves higher than others in almost all areas of cost containment and customer service. Commercial bank and credit union CEOs gave highest priority to customer retention items. Principles for improving service quality and customer retention are discussed in detail.
