The lack of reliable continuous rainfall records can exacerbate the negative impact of extreme storm events. The inability to describe the continuous characteristics of rainfall from storm events increases the likelihood that the design of hydraulic structures will be inadequate. To mitigate extreme storm impacts and improve water governance at the catchment scale, it is vital to improve the availability of data and the array of tools used to model and forecast hydrological processes. In this paper, we describe and discuss the implementation of a web-based system for the estimation of intensity–duration–frequency (IDF) curves (WEBSEIDF) in Chile. The web platform was constructed using records from 47 pluviographic gauges available in central Chile (30–40° S), with at least 15 years of reliable records. IDF curves can be generated for durations ranging from 15 min to 24 h. In addition, the extrapolation of rainfall intensity from pluviograph to pluviometric gauges (i.e., 24-h rainfall accumulation) can be carried out using the storm index (SI) method. IDF curves can also be generated for any spatial location within central Chile using the ordinary Kriging method. These procedures allow the generation of numerical and graphical displays of IDF curves, for any selected spatial location, and for any combination of probability distribution function (PDF), parameter estimation method, and type of IDF model. One of the major advantages of WEBSEIDF is the flexibility of its database, which can be easily modified and saved to generate IDF curves under user-defined scenarios, that is, changing climate conditions. The implementation and validation of WEBSEIDF serves as a decision support system, providing an important tool for improving the ability of the Chilean government to mitigate the impact of extreme hydrologic events in central Chile. The system is freely available for students, researchers, and other relevant professionals, to improve technical decisions of public and private institutions.

The Impact

The objective of the study was to determine the effect of inflation volatility on an enterprise's innovation strategy. The study showed that increasing inflation leads to a decrease in the stationary level of potential output, as well as to a decrease in the rate of economic growth in the process of transition to a stationary state. A formula is proposed for calculating the total effect of inflation on the level of enterprise output. The negative impact of the inflation rate on the welfare of economic agents was revealed, which is expressed in the fall in their equilibrium consumption level. Higher-income countries have been shown to suffer more from high inflation than poorer countries. All conclusions made in the analysis of the dynamic model of the impact of inflation on potential output are verified based on econometric modelling using methods and models for panel data: models with fixed effects, models with random effects, and a generalized method of moments. Moreover, the obtained empirical results are stable concerning changes in the specification of the equation and estimation method

The Impact

Reduced inequality and gender equality are parts of the sustainable development goals (SDGs) towards global development, but the financial sector appears daunted in respect of financial inclusion for these noble goals. Concerns are more on gender inequality in the area of full utilisation of financial and human resources. Hence, this study investigated the impact of financial inclusion on gender inequality in sub-Saharan Africa. The study employed the generalised method of moments (GMM) estimation method on panel data on some countries in sub-Saharan Africa. The result of the study revealed that financial inclusion substantially reduced gender inequality. Financial inclusion access was found to drive down gender inequality more than usage. Female educational levels were found to have a substantial but negative impact on gender inequality. This study recommends that there is a need for an increase in commercial bank branches to increase accessibility to financial services. The government should increase its expenditure, and this should be channelled towards financial development and higher levels of education for females to improve financial literacy.

The main goal of this study is to compare the impact of Web-based information on surface, deep and total learning, on satisfaction and on navigation information of subjects with different study orientations. Three subject groups were selected and each group included only subjects with a specific study orientation: A meaning study orientation, a reproduction study orientation and a disorganized study orientation. After studying a Web-based presentation on ‘Global Warming’, subject's performance was evaluated regarding surface, deep and total learning, satisfaction and navigation style. Results show that, first, subjects with a disorganized study orientation score lower on deep learning and on total learning than subjects with a reproduction study orientation and, second, subjects with a disorganized study orientation felt easier to navigate in the Web-system than subjects with a meaning study orientation (although they visit more pages and spend less time in each one than subjects with a meaning study orientation).

The Impact

<p>Several recent large flood events have had severe economic and social impacts. The winter 2015-16 UK floods resulted in 16,000 properties flooding and damage to critical infrastructure. It is increasingly being recognised that traditional approaches of flood defence are not sustainable due to the pressures of climate change and economic constraints. The solution to the flood risk problem in cities is no longer seen as being just on-site, and thinking is shifting upstream and to the catchment/landscape scales, known as Nature-Based Solutions or Natural Flood Management (NFM). The approach consists of measures that “Work with Natural Processes”, such as storing water in ponds, and slowing the flow in rivers. The evidence for the impacts is strong at the local scale, but the larger spatial scale impact is highly uncertain due to the cumulative impacts resulting from amplifying/mitigating effects of different interventions, controlled by spatial location and storm-track interaction.</p><p>To date, Nature-Based Solution schemes have proceeded on an opportunistic basis, without a clear design strategy (which measure and where to implement it). However, if schemes are implemented without clear understanding of their impacts, they may, at best, fail to achieve the optimum flood reduction benefit downstream, or, at worst, make flooding more severe (if implemented in inappropriate locations, when tributaries’ flows are synchronised).  </p><p><span>Impacts of NFM measures are spatially and temporally dependent i.e. the same intervention in two locations will have different effects on flows, and the same intervention will have different impacts during different storm events. Therefore, it is essential that when strategically designing NFM schemes for catchments, that WHERE? and WHAT? are answered together to optimise the impact, as it is possible that whilst upstream NFM may be beneficial locally it may make tributary peaks coincide and make flood magnitudes worse downstream. Here we demonstrate the importance of the spatial configuration of Nature-Based Solutions on their catchment scale effectiveness in reducing flood risk.</span></p>

The Impact

This study examines the impact of fiscal policy on agricultural output in Nigeria using the most recent official data. The metrics for fiscal policy is government capital expenditure and custom duties on fertilizer. The study used annual time series data obtained from CBN annual statistical bulletin, NCS, and FIRS which was found to be stationary at the order of I(1) and I(0). The order of unit root test led to the use of ARDL estimation method employed in the empirical analysis of this research work. The study found evidence of both short and long run relationship between the variables (VAO, GEX, IDMF, and ACGSF) using both Johansen co-integration and ARDL Bounds test. Although government expenditure (GEX) to agricultural sector was found to be statistically insignificant which recommend that government should increase agriculture capital expenditure to ensure that its contribution is significant. Consequently, custom duties on fertilizer (IDMF) was found to be negatively signed and significant indicating a negative impact on agricultural output. This demands that the policy makers should be prudent in the use of fiscal policy instrument in achieving its desired objective.

The Impact

The paper examines the impact of credits to private sector and foreign direct investment (FDI) flows on the economic growth of ASEAN countries in the period 1995-2017. The paper also validates the capital spread of FDI inflows to economic growth through credits to private sector. Using fixed effect estimation method (FEM), random effect (REM) and generalized least square (GLS) for panel data, we found that FDI inflows are positvely correlated with the economic growth of the ASEAN countries. This once again confirms the role of FDI in promoting the economic growth as evidenced in previous studies. Meanwhile, credits to private sector exert a negative impact on the economic growth in these countries which is an interesting finding given that few studies yield a similar result. To assess the spillover effect of FDI to growth through credits to private sector, we augment our model with a variable that reflects the interaction between credits to private sector and FDI. This variable is negative and statistically significant, suggesting that FDI is yet to show its positive impact on growth through spreading capital to credits to privatte sector.

The Empirical Analysis

AbstractThis paper studies the impact of official development assistance (ODA) provided by South Korea for its exports to recipient countries. The empirical analysis is based on data from 1996 to 2014 and covers 121 recipient countries. The paper uses a 3SLS estimation method that accounts for a two-way causal relationship between ODA and exports while the endogeneity and sample selection bias are accounted for. Using the gravity model, we confirm the positive effects of ODA when fixed unobserved effects are controlled. The model is further generalized by disaggregating ODA into its underlying types of aid. Our results show that technical cooperation and loans have positive and significant effects, but grants have a negative impact on South Korea’s exports to recipient countries. In addition, we also examine South Korea’s ODA allocations. Our findings suggest that there is a two-stage decision-making process in the provision of aid. In the first stage, the aid’s humanitarian purpose plays a key role in responding to countries’ needs even when there is lower bilateral trade with these countries. In the second stage, decisions regarding the size of ODA are considered and these present a mixed purpose for giving ODA to higher importer countries.

PurposeThis paper aims to introduce a web-based pilot system for minimizing the ripple effect (i.e. spreading of the negative impact of an exceptional event along the supply chain from its original position) caused by operational risks in the context of make-to-order supply chains.Design/methodology/approachThe study employs a design science research methodology, which covers three major stages: system requirements identification, business process design and the implementation and evaluation of a web-based pilot system.FindingsThe developed system has the potential to significantly reduce the negative impact of the ripple effect caused by operational risks in a make-to-order supply chain in terms of material shortages, late deliveries and subsequent additional costs associated with expediting measures when a customer order is running late.Research limitations/implicationsThe system presented in this paper is a prototype that needs to be further developed and tested in the future.Practical implicationsThis paper provides integrated business processes and useful guidelines for supply chain managers and information system developers in dealing with the ripple effect in the supply chain.Originality/valueIn contrast to prior studies that have focused on investigating the impact of the ripple effect on the supply chain caused by natural or man-made disasters, this research attempts to offer a novel approach to address the research problem (i.e. the ripple effect caused by operational risks such as delays) directly from the design science perspective.

ObjectiveTo analyse the impact of the COVID-19 pandemic on rheumatic patients’ and rheumatologists’ usage, preferences and perception of digital health applications (DHAs).MethodsA web-based national survey was developed by the Working Group Young Rheumatology of the German Society for Rheumatology and the German League against Rheumatism. The prospective survey was distributed via social media (Twitter, Instagram and Facebook), QR code and email. Descriptive statistics were calculated, and regression analyses were performed to show correlations.ResultsWe analysed the responses of 299 patients and 129 rheumatologists. Most patients (74%) and rheumatologists (76%) believed that DHAs are useful in the management of rheumatic and musculoskeletal diseases (RMDs) and felt confident in their own usage thereof (90%; 86%). 38% of patients and 71% of rheumatologists reported that their attitude had changed positively towards DHAs and that their usage had increased due to COVID-19 (29%; 48%). The majority in both groups agreed on implementing virtual visits for follow-up appointments in stable disease conditions. The most reported advantages of DHAs were usage independent of time and place (76.6%; 77.5%). The main barriers were a lack of information on suitable, available DHAs (58.5%; 41.9%), poor usability (42.1% of patients) and a lack of evidence supporting the effectiveness of DHAs (23.2% of rheumatologists). Only a minority (<10% in both groups) believed that digitalisation has a negative impact on the patient–doctor relationship.ConclusionThe COVID-19 pandemic instigated an increase in patients’ and rheumatologists’ acceptance and usage of DHAs, possibly introducing a permanent paradigm shift in the management of RMDs.

Background/Aims: The coronavirus disease of 2019 (COVID-19) pandemic has impacted the training of medical trainees internationally. The aim of this study was to assess the global impact of COVID-19 on endoscopy training from the perspective of endoscopy trainers and to identify strategies implemented to mitigate the impact on trainee education.Methods: Teaching faculty of gastroenterology (GI) training programs globally were invited to complete a 36-question web-based survey to report the characteristics of their training programs and the impact of COVID-19 on various aspects of endoscopy training, including what factors decisions were based on.Results: The survey response rate was 52.6% (305 out of 580 individuals); 92.8% reported a negative impact on endoscopy training, with suspension of elective procedures (77.1%) being the most detrimental factor. Geographic variations were noted, with European programs reporting the lowest percentage of trainee participation in procedures. A higher proportion of trainees in the Americas were allowed to continue performing procedures, and trainers from the Americas reported receiving the greatest support for endoscopy teaching.Conclusions: This study demonstrated that the COVID-19 pandemic has had a significant negative impact on GI endoscopy training internationally, as reported by endoscopy trainers. Focus-optimizing endoscopy training and assessment of competencies are necessary to ensure adequate endoscopy training.
