This study examines the impact of increasing climate variability on food production in South Africa, focusing on maize and wheat yields. A two-way fixed effects panel regression model was used to assess the climate variability impacts, analysing secondary data for the period 2000 to 2019 for nine provinces in South Africa. The study found that increasing climate variability has a negative impact on maize and wheat production in South Africa. Specifically, the results indicated a negative correlation between mean annual temperature with both maize and wheat yields. A decrease in precipitation affected maize yields negatively, while the impact on wheat yields was positive, although insignificant. This analysis, therefore, depicted that crop yields generally increase with more annual precipitation and decrease with higher temperatures. The study recommends that funding initiatives to educate farmers on increasing climate variability and its effects on farming activities in South Africa should be prioritised.

The Impact

One of the topical challenges facing South African municipalities recently is corruption. From time-to-time citizens learn about and witness the corrupt practices of public officials in the Local Government sphere. Arguably, the phenomenon of corruption has both direct and indirect impact on service delivery with specific focus to municipalities. Section 152(1) of the Constitution of the Republic of South Africa (1996) states that the Local Government sphere has the mandate to ensure the provision of services to communities in a sustainable manner. Subsequently, some of the communities across the country still wish to have access to basic services namely: water, electricity, community halls and proper tar roads to name a few. As a result, at times it seems impossible for municipalities to smoothly render such services due to corrupt practices emanating in the South African Local Government sphere. This article aimed to explore the impact of corruption on service delivery in the South African municipalities. The article fully relied on secondary data as it collects information from newspapers, books, journal articles, conference proceedings, officials report and academic dissertations. In pursuit of all this, Afrocentricity: a theory of social change has been placed in context with a view that the needs of the society should be placed at the center of the local government sphere. To be specific, these needs are but not limited to water and electricity. Looking at the findings of the study, indeed literature can confirm that corruptions have negative impact on the ability of the municipalities in South Africa to provide basic services. Because the interests of the public are competing with those of the municipal officials. Therefore, at the end of the day service delivery is compromised due unlawful practices.

The Impact

Quantitatively assessing the spatial divergence of the sensitivity of crop yield to climate change is of great significance for reducing the climate change risk to food production. We use socio-economic and climatic data from 1981 to 2015 to examine how climate variability led to variation in yield, as simulated by an economy–climate model (C-D-C). The sensitivity of crop yield to the impact of climate change refers to the change in yield caused by changing climatic factors under the condition of constant non-climatic factors. An ‘output elasticity of comprehensive climate factor (CCF)’ approach determines the sensitivity, using the yields per hectare for grain, rice, wheat and maize in China’s main grain-producing areas as a case study. The results show that the CCF has a negative trend at a rate of −0.84/(10a) in the North region, while a positive trend of 0.79/(10a) is observed for the South region. Climate change promotes the ensemble increase in yields, and the contribution of agricultural labor force and total mechanical power to yields are greater, indicating that the yield in major grain-producing areas mainly depends on labor resources and the level of mechanization. However, the sensitivities to climate change of different crop yields to climate change present obvious regional differences: the sensitivity to climate change of the yield per hectare for maize in the North region was stronger than that in the South region. Therefore, the increase in the yield per hectare for maize in the North region due to the positive impacts of climate change was greater than that in the South region. In contrast, the sensitivity to climate change of the yield per hectare for rice in the South region was stronger than that in the North region. Furthermore, the sensitivity to climate change of maize per hectare yield was stronger than that of rice and wheat in the North region, and that of rice was the highest of the three crop yields in the South region. Finally, the economy–climate sensitivity zones of different crops were determined by the output elasticity of the CCF to help adapt to climate change and prevent food production risks.

Abstract Advancing our knowledge related to honoring nursing home resident preferences is a cornerstone of person-centered care (PCC). While there are multiple approaches to providing PCC, we focus on resident preferences as assessed via the Preferences for Everyday Living Inventory (PELI). The PELI is an evidenced-based, validated instrument that can be used to enhance the delivery of PCC. In this symposium, we explore the perspectives of a variety of stakeholders including nursing home residents, staff, and the impact of preference-based care on provider level regulatory outcomes. First, we present a comparative study of preference importance among n=317 African America and White nursing home residents that found more similarities than differences between the two groups. Second, a content analysis of the responses from n=196 interviews with nursing home residents details the barriers and facilitators connected to their levels of satisfaction with their preferences being fulfilled. Third, perspectives from n=27 direct care workers explore the concept of pervasive risk avoidance to the delivery of PCC. Fourth, systems-level practices, such as shift assignments and provider schedules are identified as barriers to successfully fulfilling resident preferences from the perspectives of n=19 staff within assisted living. Our final presentation utilizes a fixed-effects panel regression analysis with n=551 Ohio nursing home providers to explore the impact of PELI use on regulatory outcomes such as substantiated complaints and deficiency scores reported in the CMS Nursing Home Compare data. Discussant Dr. Kristi Williams will integrate findings, highlighting implications for policy, practice, and future directions. Research in Quality of Care Interest Group Sponsored Symposium.

Climate change and its impact on agriculture are challenging issues regarding food production and food security. Many researchers have been trying to show the direct and indirect impacts of climate change on agriculture using different methods. In this study, we used linear regression models to assess the impact of climate on crop yield spatially and temporally by managing irrigated and non-irrigated crop fields. The climate data used in this study are Tmax (maximum temperature), Tmean (mean temperature), Tmin (minimum temperature), precipitation, and soybean annual yields, at county scale for Mississippi, USA, from 1980 to 2019. We fit a series of linear models that were evaluated based on statistical measurements of adjusted R-square, Akaike Information Criterion (AIC), and Bayesian Information Criterion (BIC). According to the statistical model evaluation, the 1980–1992 model Y[Tmax,Tmin,Precipitation]92i (BIC = 120.2) for irrigated zones and the 1993–2002 model Y[Tmax,Tmean,Precipitation]02ni (BIC = 1128.9) for non-irrigated zones showed the best fit for the 10-year period of climatic impacts on crop yields. These models showed about 2 to 7% significant negative impact of Tmax increase on the crop yield for irrigated and non-irrigated regions. Besides, the models for different agricultural districts also explained the changes of Tmax, Tmean, Tmin, and precipitation in the irrigated (adjusted R-square: 13–28%) and non-irrigated zones (adjusted R-square: 8–73%). About 2–10% negative impact of Tmax was estimated across different agricultural districts, whereas about −2 to +17% impacts of precipitation were observed for different districts. The modeling of 40-year periods of the whole state of Mississippi estimated a negative impact of Tmax (about 2.7 to 8.34%) but a positive impact of Tmean (+8.9%) on crop yield during the crop growing season, for both irrigated and non-irrigated regions. Overall, we assessed that crop yields were negatively affected (about 2–8%) by the increase of Tmax during the growing season, for both irrigated and non-irrigated zones. Both positive and negative impacts on crop yields were observed for the increases of Tmean, Tmin, and precipitation, respectively, for irrigated and non-irrigated zones. This study showed the pattern and extent of Tmax, Tmean, Tmin, and precipitation and their impacts on soybean yield at local and regional scales. The methods and the models proposed in this study could be helpful to quantify the climate change impacts on crop yields by considering irrigation conditions for different regions and periods.

Abstract The subject of research in this paper is the profitability of the biggest banks in the European financial market, some of which operate in Montenegro. The profitability of banks is influenced by a large number of factors, including internal banking and external macroeconomic factors. The aim of this paper is to use statistical and econometric methods to examine which factors and with what intensity affect the profitability of large banks in Europe. The empirical analysis used highly balanced panel models with annual data on 47 large banks from 14 European countries over the period 2013-2018. Three static panel models were estimated and evaluated (pooled ordinary least squares, model with fixed effects and model with random effects), as well as dynamic model utilizing general methods of moments. The POLS model was chosen as the best, confirming that all macroeconomic factors have a statistically significant impact on the profitability of big banks, while the impact of internal factors, which are controlled by the bank’s management, is not significant. GDP growth rate, inflation rate and market concentration have a positive effect on profitability, while the membership of the European Union has a negative impact on profit, meaning that banks with headquarters outside the EU are more profitable.

<p>O setor agrícola foi severamente afetado pela pandemia de Covid-19, gerando incertezas sobre a produção e a distribuição de alimentos, o que afetou diretamente o trabalho de milhões de agricultores. Este artigo visa a analisar o impacto da pandemia na produção de alimentos em Brasília-DF, especialmente entre os agricultores assentados/acampados da reforma agrária. Para a análise, foram utilizados dados primários obtidos através de um questionário on-line destinado ao público da reforma agrária em áreas rurais das regiões administrativas da capital federal, além de dados secundários, disponibilizados por instituições públicas. Os resultados mostraram que o impacto da pandemia foi intenso entre os agricultores, deixando-os extremamente vulneráveis, principalmente nos meses iniciais da pandemia. Como forma de enfretamento dos efeitos da pandemia, os trabalhadores adotaram quatro medidas específicas: a utilização do serviço de entrega delivery; a venda de cestas agroecológicas; a participação em redes solidárias e a venda direta em feira de reforma agrária. Essas novas dinâmicas de comercialização têm transformado as formas de interação campo-cidade ao demandar estratégias diferenciadas para alcançar os consumidores finais, contribuindo para amenizar os efeitos disruptivos da pandemia nos sistemas alimentares locais.</p><p><span>Abstract</span></p><p>IMPACTS OF COVID-19 ON FOOD PRODUCTION AND COMMERCIALIZATION IN BRASILIA-DF: CHALLENGES FOR AGRARIAN REFORM SETTLERS/CAMPED</p><p>The agricultural sector was severely affected by the pandemic of Covid-19, genera- ting uncertainties about food production and distribution, which directly affected the work of millions of farmers. This article aims to analyze the impact of the pandemic on food production in Brasília-DF, especially among farmers settled in agrarian reform settlements. The analysis used primary data obtained through an on-line questionnaire addressed to the public of agrarian reform in rural areas of the administrative regions of the federal capital, as well as secondary data made available by public institutions. The results showed that the impact of the pandemic was intense among farmers, leaving them extremely vulnerable, especially in the initial months of the pandemic. As a way of countering the effects of the pandemic, workers have adopted four specific measures: the use of delivery services; the salof agro-ecological baskets; participation in solidarity networks; and direct sales at agrarian reform fairs. These new commercialization dynamics have transformed the forms of countryside-city interaction by demanding different strategies to reach final consumers, contributing to mitigate the pandemic’s disruptive effects on local food systems.</p>

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

Purpose The purpose of this paper is to analyze the relevant aspects that influence foreign subsidiary’s performance and remain how they retain competitiveness in international markets during economic crisis. To investigate this effect, this research analyzes the behavior of Japanese subsidiaries located in European countries during the pre- and post-crisis periods that started in the USA in 2008 and spread all over the world. Design/methodology/approach This is a quantitative study with an analysis based on longitudinal data of foreign subsidiaries of Japanese multinational firms during the period 2006-2013. It applies a multiple linear regression with panel data using fixed effects models. Findings The findings show that within-firm factors related to local experiential knowledge, market entry through joint ventures with partners from the same nationality, and subsidiary management with a team of expatriates all have a positive impact on subsidiary performance during times of economic crisis. Moreover, within-country factors involving macroeconomic aspects related to inflation rate and population income indicators show a negative impact on performance. Finally, the results confirm that subsidiary performance is higher in the pre-crisis period, showing the importance of considering economic crisis aspects in longitudinal studies. Practical implications The result has implications for managers of multinational firms to understand which factors most impact the success of their foreign subsidiaries during times of economic crisis. In this way, managers can, with greater confidence, decide to reach the most important performance indicator in subsidiary management. Originality/value The majority of studies on economic crisis is based on an economic perspective and mostly investigates Asian and Argentinean crises. When considering a firm-level perspective, most research studies conducted on a subsidiary level are cross-sectional or use survival as a measure of performance. This paper applies a longitudinal study using subsidiary-level data and analyzes performance by sales and productivity measurement. In addition, it investigates whether or not within-country and within-firm factors impacted subsidiary performance during the 2008 economic crisis.

PurposeThe mechanism of marketing strategy style and its impact on firms are research issues received wide attention. In particular, the aggressive style of marketing strategy has been chosen by many companies, but recent studies have shown that it has a negative effect on corporate performance. This leads to the core issue of this paper – does the aggressive style of marketing strategy always had a negative impact on corporate performance? Are there any factors that can alleviate this negative impact?Design/methodology/approachBased on the resource-based theory and agency theory, this paper takes the Growth Enterprise Market (GEM) listed companies as the research objects, collects secondary data and conducts the research by regression model.FindingsThe empirical research shows that: (1) the aggressive style of marketing strategy significantly and negatively affects the performance of firm; (2) the resource constraint can moderate the main effect and resource control play a weak adjustment role.Practical implicationsIn practice, this paper confirms the adverse impact of aggressive style of marketing strategy on the performance of listed companies on GEM and inspires the industry to strengthen the control and supervision of marketing resources.Originality/valueThis paper makes up for the research gap in the field of cross-research in finance and marketing theoretically.
