Complex cost structures and multiple conflicting objectives make selecting an appropriate cloud service difficult. The purpose of this study is to propose a novel group consensus decision making method for cloud services selection with knowledge deficit by trust functions.

This article proposes a knowledge deficit-based multi-criteria group decision-making (MCGDM) method for cloud-service selection based on trust functions. Firstly, the concept of trust functions and a ranking method is developed to express the decision-making opinions. Secondly, a novel 3D normalized trust degree (NTD) is defined to measure the consensus levels. Thirdly, a knowledge deficit-based interactive consensus model is proposed for the inconsistent experts to modify their decision opinions. Finally, a real case study has been carried out to illustrate the framework and compare it with other methods.

The proposed method is practical and effective which is verified by the real case study. Knowledge deficit is an important concept in cloud service selection which is verified by the comparison of the proposed recommended mechanism based on KDD with the conventional recommended mechanism based on average value. A 3D NTD which considers three values (trust, not trust and knowledge deficit) is defined to measure the consensus levels. A knowledge deficit-based interactive consensus model is proposed to help decision-makers reach group consensus. The proposed group consensus model enables the inconsistent decision-makers to accept the revised opinions of those with less knowledge deficit, rather than accepting the recommended opinions averagely.

The proposed a knowledge deficit-based MCGDM cloud service selection method considers group consensus in cloud service selection. The concept of knowledge deficit is considered in modeling the group consensus measuring and reaching method.

The aim of the paper is to determine the asymmetric impact of tourism on the deficit in the balance of payments (BOPs).

The research uses the non-linear autoregressive distributed lag (ARDL) model to investigate the asymmetric impact of tourism on Pakistan's BOPs deficit using quarterly data from 1995 to 2019.

The finding reveals that due to the positive change in tourism, the BOPs deficit decreases by 27%, although due to the negative change in tourism, the BOPs deficit rises by 2.3%. In addition, the significance of F-statistics (10.609) confirms the existence of co-integration between tourism and the deficit in the BOPs. The Wald test confirms the asymmetric association between tourism and the deficit in the BOPs over the long term.

In order to improve tourism in Pakistan, policymakers must consider the following implications. First, there is a need for an adequate infrastructure that can help the tourist. Second, the Government must maintain a stable law and order situation as a whole and particularly at tourist destinations. Finally, the Government should develop tourism-friendly policies in order to boost tourism in Pakistan.

The research provides new evidence of the impact of tourism on the BOPs using the novel non-linear ARDL (NARDL) technique. The evidence will help policymakers to develop policies to improve tourism in order to reduce the BOPs deficit.

Within the theoretical frameworks of conservation of resources and job demands-resources (JD-R), the study aims to examine how sleep deficit could be negatively related to creativity at work by depleting critical resources of creativity.

The survey data were collected from 368 individuals nested in 40 teams at a call center. The authors conducted multilevel analysis to test the proposed hypotheses to account for the hierarchical nature of the data while simultaneously estimating the effect of predictors at different levels on individual-level outcomes and maintaining the predictors' level of analysis.

Through the data, the study presents how the depletion of resource, that is, emotional exhaustion, functions as a mediating mechanism that connects sleep deficit to creativity at work. Further, the study presents that higher job demands can worsen the negative effects of resource depletion on creativity at work because they further deplete resources needed for creative behaviors. Specifically, when sleep-deprived, those working in a high-task-interdependence climate are likely to experience emotional exhaustion more severely than do those in a low-task-interdependence climate. Also, the relationship between emotional exhaustion and creativity is more negative for managers than for non-managers because of managers' higher job demands.

By presenting sleep deficit-linked inhibitors of creativity at work, the authors highlight the importance of securing sufficient sleep and affective resources when designing jobs and HR practices in organizations.

This paper addresses the call for attention to examining the mechanisms through which sleep deficit affects employee creative behavior.

This study aims to evaluate the dynamics between healthcare resource capacity expansion and disease spread. Further, the study estimates the resources required to respond to a pandemic appropriately.

This study adopts a system dynamics simulation and scenario analysis to experiment with the modification of the susceptible exposed infected and recovered (SEIR) model. The experiments evaluate diagnostic capacity expansion to identify suitable expansion plans and timelines. Afterwards, two popularly used forecasting tools, artificial neural network (ANN) and auto-regressive integrated moving average (ARIMA), are used to estimate the requirement of beds for a period when infection data became available.

The results from the study reflect that aggressive testing with isolation and integration of quarantine can be effective strategies to prevent disease outbreaks. The findings demonstrate that decision-makers must rapidly expand the diagnostic capacity during the first two weeks of the outbreak to support aggressive testing and isolation. Further, results confirm a healthcare resource deficit of at least two months for Delhi in the absence of these strategies. Also, the study findings highlight the importance of capacity expansion timelines by simulating a range of contact rates and disease infectivity in the early phase of the outbreak when various parameters are unknown. Further, it has been reflected that forecasting tools can effectively estimate healthcare resource requirements when pandemic data is available.

The models developed in the present study can be utilised by policymakers to suitably design the response plan. The decisions regarding how much diagnostics capacity is needed and when to expand capacity to minimise infection spread have been demonstrated for Delhi city. Also, the study proposed a decision support system (DSS) to assist the decision-maker in short- and long-term planning during the disease outbreak.

The study estimated the resources required for adopting an aggressive testing strategy. Several experiments were performed to successfully validate the robustness of the simulation model. The modification of SEIR model with diagnostic capacity increment, quarantine and testing block has been attempted to provide a distinct perspective on the testing strategy. The prevention of outbreaks has been addressed systematically.

The effects of government expenditure on the shadow economy have been investigated. However, the effect from a moderating factor that affects this relationship has been largely ignored in the existing literature. This paper investigates how fiscal deficit moderates the effects of government expenditure on the shadow economy for 32 Asian countries for the past two decades since 2000.

The authors use various techniques, which allow cross-sectional dependence and slope homogeneity in panel data analysis, to examine this relationship in both the long run and short run. The analysis also considers the marginal effects of government expenditure on the shadow economy at different degrees of fiscal deficits.

Empirical findings from this paper indicate that an increase in government expenditure and fiscal deficit will increase the shadow economy size. Interestingly, the effects of government expenditure on the shadow economy will intensify with a greater degree of the budget deficit. The authors also find that enhancing economic growth to improve income per capita and extending international trade appears to reduce the shadow economy in the Asian countries.

The authors consider that policies targeting reducing shadow economy should follow conventional economic policies on economic growth, unemployment and inflation.

To the best of the authors’ knowledge, this is the first empirical study conducted to examine the moderating role of fiscal deficit in the government expenditure–shadow economy nexus in Asian countries.

The perpetration of sexual coercion is a complex public health problem associated with many kinds of deficits. The literature has shown that women also perpetrate sexually coercive behaviours. Recent work has suggested that this kind of behaviour could be explained by two distinct developmental pathways. However, this model does not allow the authors to identify how the individual processes social information in situ and may decide to resort to coercive behaviours. This study aimed to investigate the role of social information processing in women’s sexual coercion.

A sample of 125 French-speaking women from the general population were recruited to complete online questionnaires pertaining to dark triad personality traits, emotion abilities, alexithymia and antecedents of sexual coercion.

Results revealed that women with a history of sexual coercion had a significantly higher narcissistic traits score and more emotion regulation (ER) deficits than those without a history. For women with a history of sexual coercion perpetration, correlational analyses showed positive correlations, respectively, between psychopathic traits and alexithymia and between Machiavellianism and deficits in ER.

These results contribute to identifying the deficits relating to SIP in terms of sexual coercion perpetrated by women. Women with a history of sexual coercion perpetration appear to endorse more dark triad traits and to have ER issues. Certain level of these deficits could be a trigger and affect the SIP of women and increase the likelihood behaving in a sexually coercive manner.

This paper aims to investigate asymmetric long-run effects of bilateral exchange rate on US trade imbalances with China and to examine if the effects are the same under China’s fixed and managed floating exchange rate systems.

The authors estimate both linear autoregressive distributed lag (ARDL) model assuming symmetric effect and nonlinear ARDL model assuming asymmetric effect of exchange rate on US trade deficit with China. The authors use data from 1994Q1 to 2005Q2 (under Chinese fixed exchange rate system), from 2005Q3 to 2021Q3 (under Chinese managed floating exchange rate regime), and from 1994Q1 to 2021Q3 (overall data).

The Chow test indicates 2005Q3 is a structure break point. Further, the results suggest the effects of bilateral exchange rate on US trade deficit with China are not the same under different exchange rate systems. The asymmetric long-run effect of bilateral exchange rate does exist. The results also demonstrate the depreciation of Chinese currency will not significantly affect US trade imbalances with China.

Based on the results, the Chinese Government should embrace a more transparent and flexible exchange rate system. It will not significantly hurt Chinese trade balance, but it will help to reduce the tension between the USA and China.

All previous literature (except two papers) related to the effect of Chinese exchange rate on US trade deficit with China assume the effect is symmetric, and all (except one) use data under different Chinese exchange rate systems. To the best of the authors’ knowledge, this is the first paper that studies the possible asymmetric long-run effect of bilateral exchange rate under different Chinese exchange rate regimes.

This study aims to investigate the effect of knowledge hiding on individual task performance and examine the moderating influence of transformational leadership.

This study included 256 participants employed by financing companies in Indonesia. In addition, to analyze the data, descriptive statistics were computed using SPSS 25, and the structural equation model-partial least square (SEM-PLS) was used for hypothesis testing.

The findings revealed the negative effects of knowledge hiding on individual task performance and its potential consequences for individuals and organizations. However, it also suggested that transformational leadership may not be sufficient to reduce the negative effects of knowledge hiding on individual task performance.

This study only focused on the context of a specific industry or country, which limited the generalizability of the findings.

This study enriches the understanding of the importance of addressing knowledge-hiding behaviors and investigating additional factors that can enhance task performance in organizations.

This study adds value to the existing literature by emphasizing the importance of investigating supplementary factors other than transformational leadership that have the potential to reduce the negative effects of knowledge hiding on organizational performance.

This paper analyses the direct relationship between budget deficits and economic growth, the channels through which budget deficits inhibit growth and finally, the Granger causality between budget deficit and economic growth in South Africa over the period 1975 to 2020.

In a bid to control for endogeneity that is common in economic growth regressions, the author employed the dynamic ordinary least squares (DOLS) approach.

Towards analysing the direct relationship between budget deficit and economic growth, results show that a 10-percentage rise in the budget deficit slows economic growth by 0.2 percentage points. Results show that the growth inhibiting consequences of the budget deficit in South Africa are principally driven by negatively affecting private and public physical capital accumulation growth, as well as a drop in gross national savings. However, results show no evidence of a deficit reduction effect through long term-real interest rate. The findings reveal a one-way Granger causality running from budget deficits to economic growth.

Based on the findings in this article, expanding the fiscal deficit to support growth is not a viable policy option for the South African economy.

The originality of this paper lies in establishing the Granger causality between budget deficit and economic growth, thus adding to the scant literature, as well as establishing the channels through which budget deficit retards economic growth for the South African economy.

This study aims to assess the nexus among oil price (OP), renewable energy consumption (REC) and trade balance (TB) for India using annual time series data for the time period 1985–2019. In particular, the authors examine whether REC improves India's TB in the context of high oil import dependence.

The study uses autoregressive distributed lags (ARDL) bound testing approach that has the advantage of yielding estimates of long-run and short-run parameters simultaneously. Moreover, the small sample properties of this approach are superior to other multivariate cointegration techniques. Fully modified ordinary least square (FMOLS) and dynamic ordinary least squares (DOLS) are also applied to test the robustness of the results. The causality among the series is investigated through block exogeneity test based on vector error correction model.

The findings based on ARDL bounds testing approach indicate that OPs exert a negative impact on TB of India in both long run and short run, whereas REC has a favorable impact on the TB. In particular, 1% increase in OPs decreases TBs by 0.003% and a 1% increase in REC improves TB by 0.011%. The results of FMOLS and DOLS corroborate the findings from ARDL estimates. The results of block exogeneity test suggest unidirectional causation from OPs to TB; OPs to REC and REC to TB.

The study underscore the importance of renewable energy as a potential tool to curtail trade deficits in the context of Indian economy. Our results suggest that the policymakers must pay attention to the hindrances in augmentation of renewable energy usage and try to capitalize on the resulting gains for the TB.

Climate change is a major challenge for developing countries like India. Renewable energy sector is considered an important instrument toward attaining the twin objectives of environmental sustainability and employment generation. This study underscores another role of REC as a tool to achieve a sustainable trade position, which may help India save her valuable forex reserves for broader objectives of economic development.

To the best of the authors’ knowledge, this is the first study that probes the dynamic nexus among OPs, REC and TB in Indian context. From a policy standpoint, the study underscores the importance of renewable energy as a potential tool to curtail trade deficits in context of India. From a theoretical perspective, the study extends the literature on the determinants of TB by identifying the role of REC in shaping TB.
