Established Role

Duplex soils are prominent in southern Australia and are generally low in fertility. Their agricultural performance is, therefore, suboptimal in most circumstances without an exogenous source of nitrogen. This is often supplied by legumes which are grown in rotation with non-leguminous crops. Both crop and pasture legumes are now widely used in southern Australia and the contribution that they make to the non-legume phase of rotations is through nitrogen fixation and through other mechanisms such as cereal disease breaks. We use a mathematical programming model, MIDAS (Model of an Integrated Farming Dryland Agricultural System), to investigate the role of legumes in the low rainfall wheatbelt of Western Australia. The impact of legumes on farm profitability is assessed with a special focus on the contribution of legumes grown on a duplex soil. By using the model, the sensitivity of rotation choice on this duplex soil to changes in biological and economic parameters is explored. We conclude that crop legumes, in particular, have a firmly established role on sandy-surfaced duplex soils in low rainfall regions and that substantial increases in both the productivity and legume content of pasture would be required to outperform rotations which include crop legumes.

The Impact

The functioning of various agroecosystems is nowadays shaped by different farming systems, which may impair their functions, as well as being beneficial to them. The benefits include ecosystem services, defined as economic and noneconomic values gained by humans from ecosystems, through supporting soil formation and nutrient circulation, and the impact of agriculture on climate and biodiversity. Their mutual flow and various disturbances depend on the agroecosystem’s management method, which is associated with the type of management of agricultural land (AL) in individual farms. This paper raises a problem of transformation in the structure of three main farming systems in Poland, in 2004–2018, in relation to the implementation of 16 selected ecosystem services and their scale. Special attention was given to organic farming, as the most environmentally friendly and sustainable. The analysis demonstrates the increase in ALs in that type of production during the analyzed period of time. Disparities of transformation associated with the type of agricultural system were noticeable at the regional level, which were presented in 16 Polish voivodeships. The results of the analysis confirm that the organic system, which is an important carrier of various ecosystem services, gained a stable position. Moreover, areas with integrated farming still do not exceed 0.5% of total agricultural lands in such voivodeships. The analysis of factors influencing the deterioration or disappearance of selected environmental services characterizing agricultural systems indicates the need to depart from an intensive conventional management system.

Abstract   Childhood obesity has grown to become one of the most dramatic features of the global obesity epidemic, with long-term consequences. The spread of obesity has been fueled by changes in social norms and living environments that have shaped individual behaviours making them conducive to excessive and imbalanced nutrition, sedentary lifestyles, and ultimately obesity and associated diseases. The STOP project will aim to generate scientifically sound, novel and policy-relevant evidence on the factors that have contributed to the spread of childhood obesity in European countries and on the effects of alternative technological and organisational solutions and policy options available to address the problem. STOP will translate the evidence gathered and generated into indicators and measurements, policy briefs and toolkits and multi-stakeholder frameworks. A special focus of STOP is understanding the stakeholders' networks and drivers of stakeholders' action. STOP will establish new ways for policy-relevant evidence to be generated, made available and used in the design and implementation of effective and sustainable solutions for childhood obesity at the EU, national and local levels. Each of the policy work packages will: Produce evidence syntheses and impact simulations for different policy approaches;Assess selected policy approaches and actions in children cohorts and other relevant settings;Devise policy toolkits and policy guidance to support the adoption and implementation of specific actions by relevant actors;Establish a country-based European accountability and monitoring framework in each policy area. The workshop aims to: Showcase the impact of different policy options evaluated throughout the STOP project;Increase participants' understanding and awareness of the opportunities and challenges associated with the implementation of selected policies;Increase awareness of public health professionals of the importance of overcoming siloes in identifying and implementing public health policies;Increase the understanding of multi-stakeholder engagement. The discussion will explore the role of stakeholders across different policy areas. We will explore the different definitions of “stakeholders” and “multi-stakeholders” engagement. This will also be an opportunity to explore some of the benefits, risks and challenges around stakeholder engagement, and explore what are the different types of stakeholders involved in these policies as well as their roles. The workshop will offer an opportunity to: Inform participants about existing physical activity, regulatory and fiscal policies to address childhood obesity;Inform participants about new, innovative EU-level projects that aim to address childhood obesity;Outline preliminary findings of the STOP project with regards to the effectiveness of the evaluated policies;Identify some of the gaps and limitations of existing policies and discuss some of the steps to ensure successful policy implementation. Key messages Present new evidence on what policy approaches work in addressing key determinants of childhood obesity. Showcase findings on the attitudes of different stakeholders towards obesity policies, and debate the benefits, risks and challenges of multi-stakeholder engagement.

Progression Of Atherosclerosis

The development and progression of atherosclerosis (ATH) involves lipid accumulation, oxidative stress and both vascular and blood cell dysfunction. Erythrocytes, the main circulating cells in the body, exert determinant roles in the gas transport between tissues. Erythrocytes have long been considered as simple bystanders in cardiovascular diseases, including ATH. This review highlights recent knowledge concerning the role of erythrocytes being more than just passive gas carriers, as potent contributors to atherosclerotic plaque progression. Erythrocyte physiology and ATH pathology is first described. Then, a specific chapter delineates the numerous links between erythrocytes and atherogenesis. In particular, we discuss the impact of extravasated erythrocytes in plaque iron homeostasis with potential pathological consequences. Hyperglycaemia is recognised as a significant aggravating contributor to the development of ATH. Then, a special focus is made on glycoxidative modifications of erythrocytes and their role in ATH. This chapter includes recent data proposing glycoxidised erythrocytes as putative contributors to enhanced atherothrombosis in diabetic patients.

The Impact

Prior research has indicated that the nature of work has changed dramatically in recent years in response to economic shifts and an increasingly global economy. In part, this shift has resulted in a greater efficacy of various work-life balance and worker schedule flexibility elements in the experiences of employees in the workplace. However, little is known about the overall comparative quality of work and job satisfaction around the world in response to a shifting and increasingly interconnected global economy. In this study, we use non-panel longitudinal data from the most recent wave of the International Social Survey Program (Work Orientations IV, 2015) to conduct an exploratory comparative analysis of the impact of various workplace conditions, job characteristics, and employee attitudes in relation to comparative job satisfaction across the globe, with a special focus on the role of work-life balance and worker scheduling flexibility. Employees across the globe respond quite differently to work scenarios, which poses challenges for companies operating in multiple countries, requires adjustments to human resource practices to optimize performance levels of employees and reduce turnover expenses, and should caution managers to scrutinize their procedures to adjust to new demands in the workplace. This study adds value by making global comparisons of various workplace factors and their impact on job satisfaction using a database reflecting practices in 37 countries.

Purpose The purpose of this paper is to review the development of the German advertising industry starting from 1950 to 2018 with a special focus on the American influence. Design/methodology/approach The paper uses the oral history methodology. The content is based on 27 semi-structured interviews with current and former experts from the German and American advertising industry. An analysis of secondary sources supports the line of argumentation. Findings The paper confirms the outstanding role of the American influence on the German advertising industry, owing to new standards of professionalism, to novel versions of terminology and to the introduction of the theory of marketing. However, incompatible management styles, increasing global competition and financial pressure diminished the impact. Likewise, the American interference did not suppress the development of specific German industry characteristics such as a strong entrepreneurial culture or sustainable leadership. Originality/value This paper provides an overview of the history of German advertising with a focus on advertising agencies in the period from 1950 to today (2018). Further, this paper assesses the special impact of the American influence on the German advertising industry. Further, subjects of investigation are particularities of the German advertising industry, such as special attributes of agency leaders and their relationship with clients, distinct versions of ownership structures, agency service offerings and, finally, the role of creativity.

The Impact

Government expenditure has been considered to be having an extent of impact on economic performance at both sectoral level and aggregate national level. Evidence from literature, however shows that this notion has not been generally accepted across countries and sectors. Considering the significance of agriculture in an economy most especially in Africa, and the consequent role of government, this study examines the impact of government expenditure on agricultural productivity in South Africa using annual time series data from 1983 to 2016. It is shown that there exists a long-run relationship between government expenditure on agriculture and agricultural productivity, and a positive significant effect only to be expected in the long-run. The finding underscores the non-negotiable role of the South African government funding of agricultural sector in an era of climate change and a highly commercialized agricultural system. Furthermore, considering the low and declining pattern of government expenditure in the sector in South Africa, the desired productivity growth impact will only be experienced in the long-run all things being equal. Improving government funding in the sector could accelerate the desired agricultural productivity in the short-term.

An On farm trial was conducted at KrishiVigyan Kendra, Vaishali, Bihar to study the impact of planned honeybee pollination on the seed production and quality of Cauliflower seeds as well as pollination behavior of Apis mellifera. More number of bees were found visiting the crop under net house condition (6.05 , 5.35, 5.05 bees/plant at all the three locations of traditionally seed producing Hariharpur, Rajapakar and Chakwaravillages of Vaishali district.Bees in the open conditions were found to spend less time on flower as compared to the net house conditions. Honeybees played an important role in enhancing the seed production of cauliflower at all location under study. Planned honeybee pollination was found to result maximum impact on the seed production seeds/pod in the range of 15.50-19.10 seeds/pod in net pollination as compared to 13.60-17.20 seeds/pod in open condition. Similarly, average 1000 seed wt. in net pollinated condition was 3.30-4.19 gm whereas 3.00- 3.97 gm in open field condition, and the yield in net condition was in range 534-637 kg/ha with additional income of 14 to 17 lakh rupees per hectare.

PurposeDrawing on the signaling theory and technology acceptance model, the main purpose of this study was to predict prospective employees' intentions to apply for jobs in a firm, with a special focus on the mediating role of attitudes toward corporate websites and the moderating role of perceived value fit.Design/methodology/approachCollecting data from a convenient sample of 318 prospective job candidates, the research hypotheses were tested using structural equation modeling (SEM) with AMOS (version 24) and SPSS Process Macro (version 3.4).FindingsThe test results revealed that prospective employees' attitudes toward corporate websites partially mediate the association of corporate reputations, perceived ease of use and perceived usefulness with their intentions to apply for jobs in an organization. Noticeably, perceived value fit moderated the perceived usefulness–application intentions link in such a way that the impact of perceived usefulness on intentions to apply appears higher for individuals with a low level (than a high level) of perceived value fit.Research limitations/implicationsConsistent with the research findings, a notable theoretical contribution and practical implications for HR professionals have been discussed. This paper ends with outlining some limitations and future research directions.Originality/valueDespite having the salient buffering effects of perceived value fit on the applicant attraction process, empirical study on this theoretical phenomenon is still sparse in a pre-employment context. This may be the first study that demonstrates under what circumstances prospective employees' job pursuit intentions could be optimized in respect of their perceived value fit within a single framework comprised of two theories.

Dyslipidemia is an established risk factor for cardiovascular disease. While statin therapy remains the most important component of dyslipidemia management, a substantial proportion of patients on statin monotherapy fails to achieve guideline-recommended lipid levels. Ezetimibe is a secondline lipid-lowering agent that reduces sterol absorption, and has a favorable effect on lipid profile. This article reviews studies examining the role of ezetimibe on lipid profile, metabolic biomarkers, and cardiovascular outcomes in individuals with metabolic diseases. Special focus is given to studies in patients with dyslipidemia, Type 2 diabetes, and the metabolic syndrome. The controversy surrounding the role of ezetimibe in mitigating atherosclerosis is also highlighted. The article concludes that the ezetimibe–statin combination improves lipid parameters and helps attain guidelinerecommended lipid goals in patients with metabolic diseases. However, further research is needed to better understand the role of ezetimibe monotherapy, and the impact of ezetimibe on clinical cardiovascular outcomes.
