Deconstructing neoliberal hegemony
Authors: Lotz Corinna , Cole Penny
Published: August 2019

Neoliberal hegemony or power is seen as the contemporary form of capitalism, a social-historical formation with three dialectically-related aspects: the state, the economic system and ideological systems. These exist side by side and are interconnected and inter-dependent but they are not identical. Considering these aspects “in themselves” is a challenge, because the economic foundations of neoliberal capitalism are frequently viewed as a seamless, monolithic, omnipotent social system.The paper examines the contradictions with the neoliberal Ideal, drawing on the approach of the oppositional Soviet philosopher Evald Ilyenkov. The Ideal is internally contradictory and therefore “unquiet” with the power to stimulate action. It exists in a negated way within the individual but also has an independent existence outside the individual. It is objective because it is not the property of, or nor does it arise from one individual’s actions in the world: it is the objective form of the whole social existence of human beings.

Published: August 2019

The Australian Group on Antimicrobial Resistance (AGAR) performs regular period-prevalence studies to monitor changes in antimicrobial resistance in selected enteric Gram-negative pathogens. The 2017 survey was the fifth year to focus on blood stream infections, and included Enterobacterales, Pseudomonas aeruginosa and Acinetobacter species.
Seven thousand nine hundred and ten isolates, comprising Enterobacterales (7,100, 89.8%), P. aeruginosa (697, 8.8%) and Acinetobacter species (113, 1.4%), were tested using commercial automated methods. The results were analysed using Clinical and Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST) breakpoints (January 2018). Of the key resistances, non-susceptibility to the third-generation cephalosporin, ceftriaxone, was found in 11.3%/11.3% of Escherichia coli (CLSI/EUCAST criteria), 8.8%/8.8% of Klebsiella pneumoniae, and 5.7%/5.7% of K. oxytoca. Non-susceptibility rates to ciprofloxacin were 12.1%/18.0% for E. coli, 4.4%/11.2% for K. pneumoniae, 1.3%/3.5% for K. oxytoca, 3.0%/8.5% for Enterobacter cloacae complex, and 5.1%/9.8% for P. aeruginosa. Resistance rates to piperacillin-tazobactam were 2.8%/5.9%, 3.7%/7.3%, 9.6%/11.0%, 22.5%/27.6%, and 6.4%/13.2% for the same five species respectively. Twenty-seven isolates from 25 patients were shown to harbour a carbapenemase gene: 12 bla[IMP] (11 patients), five bla[OXA-181] (four patients), three bla[OXA-23], two bla[NDM], two bla[KPC], two bla[VIM], and one bla[GES].
Kestävän luontomatkailun uhat ja mahdollisuudet Kolin ja Urho Kekkosen kansallispuistoissa
Authors: Karhu Jani
Published: August 2019

In the past few decades, sustainable nature tourism has become one of the most growing and debatable fields of the tourism industry. This article focuses on analyzing the possibilities and threats regarding sustainable nature tourism of two Finnish national parks: Koli in North Karelia and Urho Kekkonen National Park in Lapland. The main data of the study consists of the interviews of the park managers and planners and of the survey study of the companies and societies cooperating with the parks. The main findings of the study suggest that the entrepreneurs operating in the national parks have adapted to the sustainability thinking and are developing their businesses in that regard. From the park management’s point of view, the concept of sustainable nature tourism and local cooperation by that means has been an effective tool to improve tourism and the positive attitudes towards the parks. Nevertheless, the concept of sustainability is complex, and there are multiple factors setting different expectations for tourism and the parks. This means that reaching a compromise between the park and tourism development and the limits of sustainability is more or less debatable.

Japanese Experience in Ensuring Social and Economic Security in the National Security System of the Country
Authors: Shvaiba D.
Published: August 2019

It should be noted that the global practice of ensuring the socio-economic security of the state is wide and diverse. This article discusses the practice of its enforcement in Japan. This state has accumulated significant financial and economic experience, including in matters of social and economic security. Studying the financial and economic dynamics of Japan, we will focus on the financial, economic and political aspects of ensuring socio-economic security of the state, the accompanying institutional circumstances. Scientists have noted that the financial and economic development of Japan in the post-war period is now a traditional case of realization of significant competitiveness of the state economy, in General, and some individual sectors of the economy, in particular, in the criteria of energy and raw material resources deficit. As a state with few natural resources; which was backward in almost all respects seventy years ago, Japan has transformed into a prosperous power in the world in terms of financial and economic development. However, the rise of the competitive economy is not determined by the involvement of an increasing number of means of the production process, but by the increase in the effectiveness of their application, the indicators of which act as financial and economic factors of the macro-competitiveness of the sectors of the economy, the state economy are innovative. At the same time, in recent years, the labor index as a whole had a negative impact on the financial and economic recovery, which, in our opinion, is considered a harbinger of, in-1, increasing unemployment; in-2, the situation of population aging. However, the rise in the productivity of the production process during the same time, leveled the negative impact of the presented factor and provided a cumulative recovery of the economy.

Published: August 2019

This article discusses the reform of the judicial system of the Russian Federation through the creation of separate appellate and cassation courts of General jurisdiction. The question of the competence of new courts, the composition of the court, as well as the characteristics of these courts are analyzed. In particular, attention is focused on the creation of appeal and cassation courts within the territories of the respective judicial appeal and cassation districts that do not coincide with the administrative-territorial division of the Russian Federation. In addition, attention is drawn to the establishment of a permanent judicial presence, which will be located outside the permanent seat of the court. The positive and negative sides of the reform, its expediency are analyzed. The main advantage of the judicial reform, according to the author, is the separation of the courts of appeal and cassation from the courts of first instance, which will affect the improvement of the judicial system. The author also points to the problems solved in connection with the reform of the judicial system.

Authors: Shestakova L. , Gorevskikh A.
Published: August 2019

The need for the study is substantiated by the insufficient development of the conditions for organizing activities for the formation of cognitive universal educational actions in students through the use of competence-oriented tasks. The above indicates that the problem of the formation of cognitive universal educational actions through the use of competence-oriented tasks is insufficiently developed and requires additional research. Thus, a number of contradictions were singled out: between the modern requirements of society for students, who should have perfect cognitive educational devices that do not ensure their development in a secondary school; and between the need to develop cognitive learning in the process of teaching mathematics and the insufficient elaboration of this issue in pedagogical theory and practice. The outlined contradictions testify to the relevance of the research topic and allow us to formulate its problem: what should be the conditions for the use of competent-oriented tasks in order to form cognitive universal learning activities for students (based on mathematics)? Under the terms of the organization of activities in this article we will understand the complex of special conditions created by the teacher to achieve the goals set, namely the education and training of students. In the process of conducting research, certain skills are selected that are part of the cognitive universal educational actions. For the formation of the selected characteristics was organized training activities of students in compliance with the following conditions. First, the development and implementation of the mathematical circle I am learning to analyze. Secondly, the construction of work based on the use of specific types of competence-oriented tasks. Thirdly, two types of work were used: with ready competence-oriented tasks and to transform tasks from textbooks into competence-oriented ones. Experimental work has yielded positive results. Significance of the study: the materials of the article may be useful for school teachers of mathematics.

Towards a decade of synergising corpus linguistics and critical discourse analysis: a meta-analysis
Authors: Nartey Mark , Mwinlaaru Isaac N.
Published: August 2019

The incorporation of corpus linguistics (CL) methods within critical discourse analysis (CDA) has increasingly gathered momentum over the last decade. This paper surveys studies using this triangulated framework, drawing on a database of 121 studies collected from three citation indexes: Social Sciences Citation Index, Arts and Humanities Citation Index, and Scopus. It presents a meta-analysis of these studies focussing on four variables, namely their chronological development, the domains of engagement, the issues that have been topicalised, and the area/regional coverage of the studies. In particular, the paper accounts for the factors that have contributed to the popularity of corpus-based CDA in the last decade as an approach to discourse analysis, provides insights into the evolution of this eclectic approach, and anticipates the future of the framework by offering suggestions. The paper concludes that corpus-based CDA presents both discourse analysts and corpus linguists with a robust methodology to tackle research questions bordering on discursive reflections of social issues and to identify new sites of public discourse for systematic analysis.
Paradigmatic influences on lexical bundles in research articles in the discipline of education
Authors: Candarli Duygu , Jones Steven
Published: August 2019

Lexical bundles are pervasive in English academic writing; however, little scholarly attention has been paid to how quantitative and qualitative research paradigms influence the use of lexical bundles in research articles. In order to investigate this, we created two equal-size corpora of research articles in the discipline of education. We examined four-word lexical bundles in terms of their structural characteristics and discourse functions in the quantitative and qualitative research articles published in international English-medium journals. We attribute intra-disciplinary variations in the use of lexical bundles to the knowledge-making practices that are specific to quantitative and qualitative research articles. This paper provides further evidence that the research article is not a unitary construct. The results have implications for academic writing, and corpus building and design in academic discourse. One of the key implications of this study is that L2 novice writers need to take into account the influences of research paradigms on the use of lexical bundles when writing research articles for English-medium journals in the discipline of education.
Do Non-District Donors Reward Moderates? Evidence from the Senate, 1990-2014
Authors: Keena Alex
Published: August 2019

Money from non-district donors represents a growing share of money raised in congressional elections. Yet little research has probed the links between this money and the behavior of legislators in office. I conduct a longitudinal study of the Senate (1990-2014) to understand the links between extremism in floor voting and receipts from out-of-state donors. I find that, among senators not facing reelection during a given two-year congress, there is a negative correlation between extremism and out-of-state donations, which suggests that non-district donors reward “centrists” who vote with the middle of the pack. However, this relationship disappears among senators facing reelection at the end of a congress. These results illuminate the ways in which non-district donors seek to influence the behavior of politicians through their gifts during periods of electoral safety, and suggest that senators behave strategically in order to win favor from non-state donors for support.

Authors: Bourodimos Georgios , Koutsiaras Michael , Psiroukis Vasilios , Balafoutis Athanasios , Fountas Spyros
Published: August 2019

Spray drift is one of the most important causes of pollution from plant protection products and it puts the health of the environment, animals, and humans at risk. There is; thus, an urgent need to develop measures for its reduction. Among the factors that affect spray drift are the weather conditions during application of spraying. The objective of this study was to develop and evaluate a spray drift evaluation tool based on an existing model by TOPPS-Prowadis to improve the process of plant protection products’ application and to mitigate spray drift for specific meteorological conditions in Greece that are determined, based on weather forecast, by reassessing the limits for wind speed and direction, temperature, and air relative humidity set in the tool. The new limits were tested by conducting experimental work in the vineyard of the Agricultural University of Athens with a trailed air-assisted sprayer for bush and tree crops, using the ISO 22866:2005 methodology. The results showed that the limits set are consistent with the values of the spray drift measured and follows the tool’s estimates of low, medium, and high risk of spray drift.

In Chile, durum wheat is cultivated in high-yielding Mediterranean environments, therefore breeding programs have selected cultivars with high yield potential in addition to grain quality. The genetic progress in grain yield (GY) between 1964 and 2010 was 72.8 kg ha−1 per year. GY showed a positive and significant correlation with days to heading, kernels per unit ground area and thousand kernel weight. The gluten and protein content tended to decrease with the year of cultivar release. The correlation between the δ13C of kernels and GY was negative and significant (−0.62, p < 0.05, for all cultivars; and −0.97, p < 0.001, excluding the two oldest cultivars). The yield progress (genetic plus agronomic improvements) of a set of 40–46 advanced lines evaluated between 2006 and 2015 was 569 kg ha−1 per year. Unlike other Mediterranean agro-environments, a longer growing cycle together with taller plants seems to be related to the increase in the GY of Chilean durum wheat during recent decades.

A study was conducted in an irrigated arid agroecosystem in southwestern USA, to compare two conservation tillage systems (strip tillage (ST) and no-tillage (NT)) to conventional, plow-based tillage (PT) system. Corn silage (Zea mays L.) was planted in this trial. Growth parameters (plant population and height) of corn silage were measured during the season and yield was evaluated at harvest. Soil physical measurements assessed included mean weight diameter of dry aggregates, wet aggregate stability, and penetrometer resistance. While soil biological measurements included total microbial biomass, diversity index (DI), total bacteria biomass, total fungi biomass (TFB), arbuscular mycorrhizae fungi (AMF), and total saprophytes. Results showed that plant population and silage yield at 65% moisture content were not significant with tillage during both trial years. Soil physical parameters were mostly not significant with tillage, while three out of the six biological measurements (DI, TF, and AM) were significant with tillage at p ≤ 0.05. No-tillage had higher DI and TFB than the ST, but not different from PT, while AMF was significantly higher in PT than ST, but not different from NT. The study demonstrates that farmers in the study region can adopt conservation tillage without yield losses during the early years of transition.

Chokeberry (Aronia melanocarpa L.) contains a large number of bioactive compounds, which make of it a highly nutritional and antioxidant food with anti-cancer and anti-inflammatory properties. It has been recently seen its consumption increased because of its interesting composition and properties as a functional food. The ultrasound-assisted extraction method has been optimized, since it is a simple and fast technique to extract phenolic compounds, as well as anthocyanins, not only separately but also simultaneously. Multiple response has been optimized and demonstrated an effectiveness level similar to the individual ones. This represents a considerable reduction in costs, time and work. The optimal conditions for simultaneous extractions were: 54% methanol as extraction solvent at pH 2.72 and 69.4 °C temperature, 70% amplitude, 0.7 s cycle, and 0.5:18.2 g:mL sample mass/solvent volume ratio. The developed methods showed a high precision level with coefficients of variation lower than 5%. The methods were successfully applied to commercial samples. Additionally, the extraction of other compounds of biological interest, such as organic acids and sugars, was also studied.

Use of saline water for irrigation is essential to mitigate increasing agricultural water demands in arid and semi-arid regions. The objective of this study is to address the potential of using straw biochar as a soil amendment to promote wheat production under saline water irrigation. A field experiment was conducted in a clay loam soil from eastern China during 2016/2017 and 2017/2018 winter wheat season. There were five treatments: freshwater irrigation (0.3 dS m−1), saline water irrigation (10 dS m−1), saline water irrigation (10 dS m−1) combined with biochar of 10, 20, 30 t ha−1. Saline water irrigation alone caused soil salinization and decreased wheat growth and yield. The incorporation of biochar decreased soil bulk density by 5.5%–11.6% and increased permeability by 35.4%–49.5%, and improved soil nutrient status. Biochar also reduced soil sodium adsorption ratio by 25.7%–32.6% under saline water irrigation. Furthermore, biochar alleviated salt stress by maintaining higher leaf relative water content and lower Na+/K+ ratio, and further enhanced photosynthesis and relieved leaf senescence during reproductive stages, leading to better grain formation. Compared to saline water irrigation alone, biochar application of 10 and 20 t ha−1 significantly increased wheat grain yield by 8.6 and 8.4%, respectively. High dose of biochar might increase soil salinity and limit N availability. In the study, biochar amendment at 10 t ha−1 would be a proper practice at least over two years to facilitate saline water irrigation for wheat production. Long-term studies are recommended to advance the understanding of the sustainable use of straw biochar.

The Midwestern U.S. landscape is one of the most highly altered and intensively managed ecosystems in the country. The predominant crops grown are maize (Zea mays L.) and soybean [Glycine max (L.) Merr]. They are typically grown as monocrops in a simple yearly rotation or with multiple years of maize (2 to 3) followed by a single year of soybean. This system is highly productive because the crops and management systems have been well adapted to the regional growing conditions through substantial public and private investment. Furthermore, markets and supporting infrastructure are highly developed for both crops. As maize and soybean production have intensified, a number of concerns have arisen due to the unintended environmental impacts on the ecosystem. Many areas across the Midwest are experiencing negative impacts on water quality, soil degradation, and increased flood risk due to changes in regional hydrology. The water quality impacts extend even further downstream. We propose the development of an innovative system for growing maize and soybean with perennial groundcover to recover ecosystem services historically provided naturally by predominantly perennial native plant communities. Reincorporating perennial plants into annual cropping systems has the potential of restoring ecosystem services without negatively impacting grain crop production and offers the prospect of increasing grain crop productivity through improving the biological functioning of the system.

The Ethiopian fruit fly (EFF), Dacus ciliatus, is a key, invasive pest of melons in the Middle East. We developed and implemented a novel decision support system (DSS) to manage this pest in a greenhouse environment in Southern Israel. Dacus ciliatus is commonly controlled in Israel with repeated calendar-sprayings (every 15 days) of pyrethroid pesticides. The current study compares the performance of a DSS against calendar-spraying management (CSM). DSS was based on EFF population monitoring and infestation. DSS took into consideration concerns and observations of expert managers and farmers. During 2014, EFF damage was concentrated in the spring melon production season. Fall and winter production did not show important damage. Damage during the spring of 2014 started to increase when average EFF/trap/day reached 0.3. This value was suggested as the threshold to implement pesticide spraying in DSS greenhouses. EFF/trap/day trends were derived from monitoring with conventional traps and a novel electronic remote sensing trap, developed by our group. CSM during the spring of 2015 included 3 EFF control sprays, while DSS-managed greenhouses were only sprayed once. At the end of the spring season, damage was slightly higher in DSS greenhouses (1.5%), but not significantly different to that found in CSM greenhouses (0.5%). Results support continuing DSS research and optimization to reduce/remove pesticide use against EFF in melon greenhouses. Interactions with farmers and managers is suggested as essential to increase adoption of DSS in agriculture.
Change the Humans First: Principles for Improving the Management of Free-Roaming Cats

Published: August 2019

In Australia, free-roaming cats can be found in urban and rural areas across the country. They are inherently difficult to manage but it is frequently human behaviour that demands the most attention and is in most need of change. To the frustration of policy makers and practitioners, scientific knowledge, technological developments, and legal and institutional innovations, often run afoul of insufficient public capacity, opportunity and motivation to act. This paper demonstrates how the behavioural science literature can provide important insights into maximising the impact of free-roaming cat control activities within an ethical framework that prioritises acting “with” all stakeholders, rather than “on” stakeholders. By better understanding how human values, attitudes and beliefs are shaped, practitioners can more effectively and respectfully interact with how people interpret the world around them, make choices and behave. This literature also has much to say about why certain types of media and marketing messages elicit behaviour change and why other types fall flat. Finally, in addition to explaining the behavioural science and its implications, this review provides researchers, policy makers and engagement specialists with an inclusive, practical framework for conceptualising behaviour change and working to ensure land managers, cat owners and the general public can agree on and adopt best practices for managing free-roaming cats.
