Everyday Life Ecologies: Crisis, Transitions and the Aesth-Etics of Desire
Authors: Gobbo Alice Dal
Published: May 2020

Everyday life practices are one of the focuses of interest for so-called ‘sustainable transitions’. Efforts in making daily life more ecological have ranged from awareness-raising and behaviour change strategies to socio-technical innovations, but have produced limited results so far. In a present characterised by a prolonged and multifaceted crisis it is imperative that, as social scientists, we interrogate the (un)sustainability of everyday practices from a more critical angle, linking them to reflections about capitalism's ecological destructiveness. One fruitful way of doing so is to interrogate the dimension of subjectivity as a space where collective discourses, practices and desires are embodied in concrete experience and actions. Drawing on ethnographic material on everyday energy use, I suggest that contemporary ways of living certainly contribute to the overall reproduction of capitalism and yet, in the (dis)juncture of the crisis, more sustainable livelihoods can be experimented with and prefigured. Subjectivity is one crucial dimension in which this process unravels.

Planificación de comidas para la diabetes: manejo de la ingesta de carbohidratos
Authors: Gal Nancy , Dahl Wendy J. , Mendoza Daniela Rivero
Published: May 2020

Mantener una ingesta constante de carbohidratos durante todo el día es un método eficaz de planificación de comidas para ayudar a mantener su objetivo de niveles de glucosa en sangre. Los alimentos que contienen carbohidratos tienen el mayor efecto sobre los niveles de glucosa en sangre en comparación con los alimentos que contienen principalmente proteínas o grasas. Los carbohidratos en los alimentos que contribuyen a la glucosa en la sangre incluyen azúcares y almidones. Los alimentos que contienen carbohidratos se dividen en grupos según su similar contenido de carbohidratos por porción. La cantidad de carbohidratos que consuma se basa en sus objetivos de tratamiento de la diabetes y la tolerancia a los carbohidratos.

Asian longhorned tick, Haemaphysalis longicornis Neumann (Arachnida: Acari: Ixodidae)
Authors: Tian Yuexun , Kaufman Phillip E
Published: May 2020

The Asian longhorned tick, Haemaphysalis longicornis Neumann, also known as the longhorned tick, bush tick (Australia), and cattle tick (New Zealand), is a three-host tick native to East Asia. This tick has been categorized as an invasive species in Australia, New Zealand, and several Pacific Islands. In the U.S., an Asian longhorned tick infestation was recorded in New Jersey during the fall of 2017. This tick is somewhat unique in that females are capable of parthenogenesis, meaning that females can produce offspring without having mated with males. The Asian longhorned tick feeds on a wide range of hosts including birds and mammals, including humans. This tick is considered a medical and veterinary vector due to its ability to transmit pathogens that cause disease in humans and other animals.https://edis.ifas.ufl.edu/in1263

Authors: Hong Cheng-Fang , Zhang Shouan , Gazis Romina , Crane Jonathan H , Wasielewski Jeff
Published: May 2020

Dragon fruit, also known as pitahaya, pitaya, and strawberry pear, is a group of vine-like, climbing cacti. In south Florida, production of dragon fruit has been steadily increasing since the 2000s, and growers in Florida consider dragon fruit as a potential alternative fruit crop to avocado and citrus, two economically important fruit crops largely impacted by laurel wilt and huanglongbing, respectively. This new 4-page article focuses on the symptomology and epidemiology of stem and fruit canker, a prevailing disease on dragon fruit. Suggested management strategies for the disease are also discussed based on recent studies conducted in south Florida. Written by Cheng-Fang Hong, Shouan Zhang, Romina Gazis, Jonathan H.

Everglades Agricultural Area Soil Subsidence and Sustainability
Authors: Bhadha Jehangir H , Wright Alan L , Snyder George H
Published: May 2020

This 4-page major revision, a publication of the UF/IFAS Department of Soil and Water Sciences, highlights the current status of Histosols within the Everglades Agricultural Area in southern Florida. Over the last century, soils within the region have gradually been lost via oxidation, a process commonly referred to as soil subsidence. The rate of subsidence is gradually declining, due to factors such as increased mineral content in soil, humification, and water management (maintenance of higher water tables). Best Management Practices and crop rotation help slow down the rate of oxidation and promote soil sustainability within the region. Written by Jehangir H. Bhadha, Alan L. Wright, and George H.

Facts about Wildlife Diseases: Bats and Coronaviruses
Authors: Ober Holly K. , Wisely Samantha M.
Published: May 2020

Bats make valuable contributions to natural ecosystems and provide benefits to people. We explain below how some unusual physical adaptations allow bats to harbor viruses that cause no harm to themselves but cause grave illness in humans. Transmission of these pathogens from bats to humans can occur only when humans have close interactions with bats and contact with their bodily fluids. A number of strategies could reduce the likelihood of bat viruses crossing over to humans, such as restrictions on harvesting of bats as bushmeat, curtailment of live wildlife markets, enforcement of regulations on illegal wildlife trade, and limiting deforestation and cave vandalism to reduce movement of bats into close proximity to humans. Enhancing efforts to protect bat roosts can reduce the likelihood of future zoonotic disease pandemics while also increasing the natural pest reduction services bats provide as they consume insects that cause damage to agronomic crops. Protecting bat roosts can also benefit human health by ensuring bats continue to consume mosquitos responsible for transmitting diseases such as Zika, Dengue, Malaria, and Chikungunya.
Icebreakers for Adults
Authors: Stein Megan , Nash Taylor
Published: May 2020

Building rapport is key when creating a team culture. As groups change over time, it is imperative to continually reintroduce and reacclimate new team members to long-standing teammates. Leaders of groups that undergo constant change, like those whose jobs involve volunteers, may find it challenging to find innovative ways to bring people together. Icebreakers are quick, low- or no-cost activities that allow individuals to get to know the people around them and serve as a means to build trust and openness in a low-stakes environment. This new 3-page publication of the UF/IFAS Department of Agricultural Education and Communication outlines strategies to use when building a team culture and gives examples of simple activities to build cultures within teams or groups.

Obtaining World Coordinate Information of UAV in GNSS Denied Environments
Authors: Chen Chengbin
Published: May 2020

The GNSS information is vulnerable to external interference and causes failure when unmanned aerial vehicles (UAVs) are in a fully autonomous flight in complex environments such as high-rise parks and dense forests. This paper presents a pan-tilt based visual servoing (PBVS) method for obtaining world coordinate information. The system is equipped with an Inertial Measurement Unit (IMU), an air pressure sensor, a magnetometer, and a pan-tilt-zoom(PTZ) camera. In this paper, we explain the physical model and the application method of the PBVS system which can be briefly summarized as follows. We track the operation target with a UAV carrying a camera and output the information about the UAV's position and the angle between the PTZ and the anchor point. In this way, we can obtain the current absolute position information of the UAV with its absolute altitude collected by the height sensing unit and absolute geographic coordinate information and altitude information of the tracked target. We have set up an actual UAV experimental environment. In order to meet the calculation requirements, some sensor data will be sent to the cloud through the network.Through the field tests, it can be concluded that the systematic deviation of the overall solution is less than the error of ordinary GNSS sensor equipment, and it can provide navigation coordinate information for the UAV in complex environments. Compared with traditional visual navigation systems, our scheme has the advantage of obtaining absolute, continuous, accurate and efficient navigation information in a short distance (within 15m from the target). This system can be used in scenarios that require autonomous cruise, such as self-powered inspections of UAVs, patrols in parks, etc.
Short-Chain Fatty Acids
Authors: Markowiak-Kopeć Paulina , Śliżewska Katarzyna
Published: May 2020

The relationship between diet and the diversity and function of the intestinal microbiomeand its importance for human health is currently the subject of many studies. The type and proportionof microorganisms found in the intestines can determine the energy balance of the host. Intestinalmicroorganisms perform many important functions, one of which is participation in metabolicprocesses, e.g., in the production of short-chain fatty acids—SCFAs (also called volatile fatty acids).These acids represent the main carbon flow from the diet to the host microbiome. Maintainingintestinal balance is necessary to maintain the host’s normal health and prevent many diseases.The results of many studies confirm the beneficial effect of probiotic microorganisms on the balanceof the intestinal microbiome and produced metabolites, including SCFAs. The aim of this review is tosummarize what is known on the effects of probiotics on the production of short-chain fatty acidsby gut microbes. In addition, the mechanism of formation and properties of these metabolites isdiscussed and verified test results confirming the effectiveness of probiotics in human nutrition bymodulating SCFAs production by intestinal microbiome is presented.
From Environment to Genome and Back: A Lesson from HFE Mutations
Authors: Rametta Raffaella , Meroni Marica , Dongiovanni Paola
Published: May 2020

The environment and the human genome are closely entangled and many genetic variations that occur in human populations are the result of adaptive selection to ancestral environmental (mainly dietary) conditions. However, the selected mutations may become maladaptive when environmental conditions change, thus becoming candidates for diseases. Hereditary hemochromatosis (HH) is a potentially lethal disease leading to iron accumulation mostly due to mutations in the HFE gene. Indeed, homozygosity for the C282Y HFE mutation is associated with the primary iron overload phenotype. However, both penetrance of the C282Y variant and the clinical manifestation of the disease are extremely variable, suggesting that other genetic, epigenetic and environmental factors play a role in the development of HH, as well as, and in its progression to end-stage liver diseases. Alcohol consumption and dietary habits may impact on the phenotypic expression of HFE-related hemochromatosis. Indeed, dietary components and bioactive molecules can affect iron status both directly by modulating its absorption during digestion and indirectly by the epigenetic modification of genes involved in its uptake, storage and recycling. Thus, the premise of this review is to discuss how environmental pressures led to the selection of HFE mutations and whether nutritional and lifestyle interventions may exert beneficial effects on HH outcomes and comorbidities.

A high-fat diet and obesity, the development of which is encouraged by the western lifestyle, can significantly affect male fertility. An inappropriate diet may be directly related to the increase of oxidative stress, but also contribute to the development of obesity, which is associated with the deterioration of fertility, both in terms of generating oxidative stress as well as hormonal or immunological disorders. In obese individuals, disorders on the hypothalamic-pituitary-gonadal axis are observed, as well as elevated oestrogen levels with simultaneous decrease of testosterone, LH and FSH hormone levels.
Weight loss in obese men seems to be the first, and the most basic step in the treatment of male infertility.

At present, microalgae are industrially produced mainly for the extraction of high-value products for food additives. At the same time, the microalgae possess also environmental advantages as it can be used for wastewater treatment, mitigation of industrial CO2 emissions as well as for oxygen production and atmospheric CO2 capturing. Due to increasing the environmental problems, it is reasonable to expand the “green” applications of microalgae and increase significantly their output. From this point of view, the problem of utilization of the microalgal biomass becomes more important and one of the most reliable ways to do it is a conversion of the biomass to a biofuel. It is expected that such a conversion can be implemented into the existing infrastructure for traditional hydrocarbons. In the case of microalgae, the hydrothermal liquefaction (HTL) with the production of bio-oil as a target product has attracted more attention in recent years because the bio-oil can be used in the existing refinery industry. The paper is also concerned with the use of microalgae to solve the environmental issues on the basis of HTL as a convenient and efficient method for the biomass-to-biofuel conversion. The known advantages of the HTL are the possible use of fresh microalgae just after harvesting, the processing of the whole biomass and high thermodynamic efficiency. In the paper it is shown that the latter is achieved due to the high HTL pressure that keeps the high-temperature potential of aqueous media after hydrothermal treatment and so creates the opportunity of more efficient heat recovery. The fundamental aspects of the process thermodynamics are discovered in the paper. It is shown that one of the main advantages of the process is provided by a combination of thermodynamic parameters. The problem of solar radiative transfer in photobioreactors with suspended microalgae and the desired thermophysical properties of the refined biofuels are also briefly discussed in the paper.
Trazar un lugar en la memoria. Mnemotecnias en los planos, mapas y dibujos de isla Dawson de Miguel Lawner
Authors: Accatino Sandra
Published: May 2020

Durante los primeros meses de la dictadura en Chile encabezada por el general Augusto Pinochet, el arquitecto Miguel Lawner fue recluido en la isla Dawson, en el extremo austral de Chile. En ese tiempo, memorizó los planos del centro de detención y del campo de concentración en los que estuvo prisionero y realizó una serie de dibujos con el objeto de preservar la memoria de esos lugares y los hechos allí ocurridos. A partir del imperativo “no olvidaremos”, que Lawner escribió en uno de los planos, este ensayo analiza la compleja trama gráfica de esos materiales a la luz de las antiguas técnicas del ars memoriae y revela su función como dispositivos que elaboran, registran y ordenan contenidos de la memoria.
La imagen urbana revisitada desde los imaginarios migrantes latinoamericanos. El caso de la calle Maruri en Santiago, Chile
Authors: Inzulza Contardo Jorge , Gallardo Frías Laura , Castillo Espinoza Eduardo , Cambiaso Hott Alexandra
Published: May 2020

Han pasado casi seis décadas desde que La imagen de la ciudad de Kevin Lynch lograra posicionarse en la academia global como una metodología relacional para entender la morfología de la ciudad. Si bien este concepto se mantiene dentro de las premisas urbanas vigentes y con aplicación sobre los procesos de diseño y mejoramiento en barrios y ciudades, se requiere de nuevas visiones que integren el actuar de los residentes, retratadas por medio de sus propios imaginarios. El presente artículo posiciona el debate y la aplicación de la imagen urbana desde una visión dinámica, emergida desde la revisión del propio Lynch (1995) que permite aplicarse en las actuales prácticas socioespaciales de migrantes latinoamericanos en centros urbanos, y cómo sus imaginarios urbanos se transforman en activos culturales. Situados en la calle Maruri, en Santiago de Chile, se adopta un enfoque cualitativo multidisciplinar que combina el análisis clásico de la imagen urbana de Lynch (1960) con registros visuales en esta área central, de manera de comprender la experiencia del residente migrante respecto de sus apropiaciones del espacio público. Los resultados muestran que estas prácticas socioespaciales de los migrantes, en tanto nuevos residentes, están permitiendo amplificar el significado y uso de la calle, reactivando espacios de transición como la fachada y la platabanda con nuevos usos que prolongan la actividad barrial y la integración cultural. Se concluye que el vínculo entre “imagen e imaginario” requiere una relación recíproca e indisoluble para ser transformada en normativa urbana y, de esta forma, permear en la planificación urbana en materia de integración social y programas específicos de mejoramiento barrial.
Trans Men and Trans Women
Authors: Rome Julian
Published: May 2020

This paper addresses one of the ways in which transgender individuals identify with respect to personal history, living “stealth,” whereby transgender individuals do not disclose their transgender status (that is, they present themselves as cisgender), oftentimes no longer considering themselves transgender. Individuals who live stealth are often criticized for inauthenticity; thus, this paper analyses Sartrean notions of authenticity and personal history, thereby arguing that the person who lives stealth is not living inauthentically but rather is constituting their conception of self through their past, present, and future projects.
When Language Breaks
Authors: Heft Peter
Published: May 2020

In “Logic and Conversation,” H. P. Grice posits that in conversations, we are “always-already” implying certain things about the subjects of our words while abiding by certain rules to aid in understanding. Itis my view, however, that Grice’s so-called “cooperative principle” can be analyzed under the traditional Heideggerian dichotomy of ready-to-hand and presentat-hand wherein language can be viewed as a “mere” tool that sometimes breaks. Ultimately, I contend that the likening of language to a tool allows for a more robust understanding of it and conversational failures, while ontologically recategorizing language as an object of sorts.
On Methodologies of Resisting Testimonial Injustice
Authors: Humphreys Christopher
Published: May 2020

Testimonial injustice, in its most pernicious form, subjects a speaker to identity-prejudicial deficits in the credibility that is rightly due their testimony. This paper compares two prominent accounts of testimonial injustice to determine which achieves the best understanding of the phenomenon and how it can be combatted. Where Fricker’s focus is limited to strictly epistemic wrongs, Medina’s analysis extends to the pertinent non-epistemic elements central to the injustice. Thus, Medina’s methodology is better-suited to the task of phenomenological analysis, and positions us to achieve a more complete understanding of what injustice has been perpetrated, and of how to resist it.
The Ethical Implications of Evolutionary Theory
Authors: Parker Marc Anthony
Published: May 2020

This essay is primarily concerned with important arguments involved in the debate about the relationship between evolution and morality. Though the paper holds that it is plausible that certain natural traits would have evolved into human moral sentiments, it argues that evolutionary theory cannot tell us how to be good people or why moral sentiments ought to take priority over immoral sentiments. Evolutionary theory is in this way an incomplete moral theory, analyzing how humans and human morality evolved through natural selection can uncover implications of evolutionary theory, which have a strong impact on a theory of morality
A Critical Assessment of George Klosko’s Version of the Principle of Fair Play
Authors: Moauro Leonardo
Published: May 2020

The nature of our obligation to obey the law has consistently been an important object of philosophical dispute. Fair play based theories of obligation purport to show that it is unfair for us to benefit from anorganizational scheme (such as the state) without contributing our fair share to the provision of goods. George Klosko is a major proponent of this approach. I develop his particular version of the argument from fair play into a defensible theory of citizens’ obligation to obey the laws of their state.
Change and Moral Development in Kant’s Ethics
Authors: Curran Kyle
Published: May 2020

This paper is concerned with an ambiguous aspect of Kant’s ethics, namely, how moral change is possible. Kant conceives that change is possible, indeed desirable, without making clear the mechanism by which this change occurs. I conclude that one’s moral development must come about through the autonomous rationality of humanity. This allows for the moral law to be held at all times and for the rejection of immoral sentiments and inclinations. Further, it is constant soulsearching that allows one to keep a check on their maxims, facilitating the development of a moral disposition.
Purity Balls
Authors: Doolen Nicole B.
Published: May 2020

In this paper, I draw on the principles of Aristotelianethics, the work of modern virtue ethicists, and previous feministcritiques of purity balls to interrogate the effects of this practiceon moral development. I argue that purity balls discourage youngwomen from making autonomous, informed, and virtuouslymotivated decisions regarding their sexuality. While most critiquesof purity balls are rooted in the explicitly patriarchal structure ofthese events, my analysis emphasizes the negative impact they haveon moral agency. I conclude that purity balls are unethical becauseof the detrimental effects they have on the becoming of virtuousagents.

The Labour Market of Chinese Cruise Seafarers: Demand, Opportunities and Challenges
Authors: Li Hua , Zhang Pengfei , Tong Helong
Published: May 2020

The rapid development of the Chinese cruise market has brought with it an urgent increase in demand for Chinese cruise seafarers. This brings great opportunities and challenges to the Chinese seafarer labour market. This research aims to contribute to this relatively understudied area by calculating the demand for Chinese cruise seafarer, and understanding the Chinese seafarers' labour market from the aspects of training, recruitment and their work experience on ships. In order to achieve this objective, a demand model is constructed through the idea of market-driven, in-depth interviews using a detailed questionnaire. The study estimates that the total demand for Chinese cruise seafarers in 2020 will be 29,200 and 100,000 in 2030. This reveals a predicted gap between demand and supply of 19,200 in 2020. The current source of seafarers is mainly from domestic shipping companies, hotels and related institutions. Their entry age is relatively young, current job profiles are mostly those in the capacity of assistants and the average wage is $1217. Thus, there is a lot of room for improvement with their increasing experience. The study has found that most seafarers on board are satisfied with the work on cruise ships and are more concerned about their career development rather than salary. English communication skills and practical skills are two important aspects of crew training. China's cruise ship labour market thus represents both, a high aggregate demand as well as the lack of high-end experienced talent. Labour market policies and systems in China remain to be improved.
Factors Influencing Green Purchase Behavior among Young Consumers in Saudi Arabia
Authors: Mohammed Abdulalem , Homaid Abdo , Alaswadi Wail
Published: May 2020

For environmental and business reasons, understanding the consumer behaviour of the young towards green products is very important. Therefore, the main purpose of this study is to investigate the factors influencing green product buying intention and behaviour among young consumers in Saudi Arabia. The study has developed a set of hypotheses utilising the theory of planned behaviour (TPB) as a guiding principle. They were tested based on data collected from 257 individuals through the use of the Partial Least Square (PLS) method. The findings showed that a culture of collectivism was the best way to predict the green purchasing intentions of young Saudis, followed by a willingness to pay, environmental self-identity and peer pressure. Additionally, purchasing intention is a major factor influencing actual green purchasing behaviour.

This study aimed to determine the factors associated with the occurrence of body weight below the red line in toddlers in the working area of Karang Intan 1. This study used analytic survey methods with cross-sectional approach. This study population was all toddlers, amounting to 801 people and a sample of 267 people with the purposive sampling method. The instrument used a questionnaire. The test used was the Chi-Square statistical test. The results showed a relationship between the history of exclusive breastfeeding (ρ=0.001), feeding patterns (ρ=0,000), history of infectious diseases (ρ=0.042), maternal visits to Integrated healthcare center (Posyandu) (ρ=0.002), family economic status (ρ =0,0151) with the occurrence of body weight below the red line (BGM) in infants. Conclusion: there is a relationship between exclusive breastfeeding, eating care, history of infectious diseases, maternal visits to the Posyandu, family economic status towards the occurrence of body weight below the red line in toddlers. Parenting is a significant determinant of BGM events. These determinants can be used for screening the development and growth of infants.
Trabajo colaborativo en el aula, bullying y cyberbullying: Estudio con adolescentes
Authors: Chacón Cuberos Ramón , Epelde Larrañaga Amaya , Oñederra Ramírez José Antonio
Published: May 2020

El acoso escolar se ha convertido en una práctica común entre adolescentes y especialmente a través del cyberbullying. Estas prácticas generan graves problemas en un colectivo en desarrollo cognitivo, social y emocional, siendo esencial actuar preventivamente. Se realizó un estudio de tipo descriptivo y corte transversal en una muestra de 227 adolescentes de Melilla (España), el cual perseguía analizar las relaciones existentes entre bullying, cyberbullying y prácticas de trabajo cooperativo. Se emplean como principales instrumentos el test de cyberbullying (Garaigordobil, 2013) y un cuestionario de trabajo en equipo mediante validación de expertos. Los resultados revelan que el trabajo cooperativo es más elevado en las chicas, disminuyendo el mismo con la edad. El trabajo grupal se relacionó inversamente con las situaciones de acoso. También se observó que a mayor edad se sufre más victimización ligada a cyberbullying e incrementan las situaciones en las que se es agresor. Se concluye cómo el trabajo cooperativo en las aulas puede actuar preventivamente ante situaciones de acoso al ayudar a construir mejores relaciones entre pares e identidad de grupo.

Uno de los componentes de las secuencias fue la posición mientras los otros dos variaron en propiedad dimensional: colores y/o números. El Experimento 1 evaluó las diferencias en el aprendizaje y recuerdo de una secuencia de colores o números. Los resultados mostraron que la secuencia de números se aprendió más rápido que la de colores. El Experimento 2 buscó aislar el efecto del aprendizaje inicial de la secuencia de posiciones sobre el aprendizaje y recuerdo posterior de una secuencia de colores o números superpuesta a la secuencia de posiciones ya aprendida. Los resultados mostraron que aprender inicialmente la secuencia de posiciones facilitó el aprendizaje de los componentes posteriores de la secuencia. El análisis se orienta a la identificación de un gradiente de posición como factor explicativo del aprendizaje de este tipo de secuencias; además se propone la existencia de un efecto de la dimensión de los componentes de las secuencias en su aprendizaje y recuerdo. Finalmente, se analizan las funciones atípicas obtenidas en las curvas de posición serial de los dos experimentos.

Existe una estrecha relación entre la creencia en mitos románticos acerca de las relaciones de pareja y la presencia de dependencia emocional debido a que dichas creencias promueven que las necesidades e intereses individuales se dejen en un segundo plano. El objetivo de la presente investigación consistió en identificar si existen diferencias en función del nivel educativo de los individuos en la relación existente entre la presencia de mitos románticos y la dependencia emocional en la relación de pareja y para ello se trabajó con 34 estudiantes de bachillerato y 61 estudiantes de licenciatura, a quienes se les aplicó la Escala de Mitos, Falacias y Creencias Amorosas Erróneas del Amor Romántico y un cuestionario de Dependencia Emocional. Los resultados muestran que los alumnos de bachillerato tienen puntajes más altos en dependencia emocional y mayor aceptación de los mitos. En el alumnado universitario se encontraron más correlaciones entre mitos y dependencia que en el estudiantado de bachillerato. Palabras clave: dependencia emocional, mitos del amor, relación de pareja

Land-use changes and especially management intensification currently pose a major threat to biodiversity both on and beneath the soil surface. With a comparative approach, we investigated how management intensity in orchards and meadows influences soil macro-invertebrate communities in a North-Italian Alpine region. We compared soil fauna assemblies from traditional low-input sites with respective intensively managed ones. As expected, the taxonomical richness and diversity were lower in both intensive management types. Extensive management of both types revealed similar communities, while intensification led to substantial differences between management types. From these results, we conclude that intensification of agricultural practices severely alters the soil fauna community and biodiversity in general, however, the direction of these changes is governed by the management type. In our view, extensive management, traditional for mountain areas, favors soil fauna communities that have adapted over a long time and can thus be viewed as a sustainable reference condition for new production systems that consider the protection of soil diversity in order to conserve essential ecosystem functions.

The introduction of nitrogen fixing bacteria (NFB) and arbuscular mycorrhizal fungi (AMF) into the soil is an advisable agricultural practice for the crop, since it enhances nutrient and water uptake and tolerance to biotic and abiotic stresses. The aim of this work was to study plant nutrition, biological nitrogen fixation (BNF) and crop yield and quality, after inoculating seeds with NFBs ((Rhizobium leguminosarum, Burkholderia cenocepacia, Burkholderia vietnamiensis)) and/or AMFs (Rhizophagus irregularis, Claroideoglomus etunicatum, Claroideoglomus claroideum and Funneliformis mosseae) in a fava bean crop in two seasons. The composition of the nodule bacterial community was evaluated by the high-throughput sequencing analysis of bacterial 16 S rRNA genes. It was found that microbial inoculation accompanied by a 20% decrease in mineral fertilization had no significant effect on crop yield or the nutritional characteristics compared with a non-inoculated crop, except for an increase in the grain protein content in inoculated plants. None of the inoculation treatments increased biological nitrogen fixation over a non-inoculated level. The bacterial rRNA analysis demonstrated that the genus Rhizobium predominated in all nodules, both in inoculated and non-inoculated treatments, suggesting the previous presence of these bacteria in the soil. In our study, inoculation with Rhizobium leguminosarum was the most effective treatment for increasing protein content in seeds, while Burkholderia sp. was not able to colonise the plant nodules. Inoculation techniques used in fava beans can be considered an environmentally friendly alternative, reducing the input of fertilizers, while maintaining crop yield and quality, with the additional benefit of increasing the grain protein content. However, further research is required on the selection and detection of efficient rhizobial strains under local field conditions, above all those related to pH and soil type, in order to achieve superior nitrogen-fixing bacteria.

Temperature strongly influences the growth of maize, particularly in the early growth stages. The exogenous application of some amino acids has been proven to have a positive effect on plant growth and development under stressful conditions. The objective of the study was to evaluate the response of maize that was grown under an optimal and stress (fluctuating) temperature to L-Arginine (L-Arg) and Glycine (Gly) application. In the study, it was assumed that the exogenously applied amino acids would alleviate the adverse effects of temperature stress on the maize height, as well as on the biomass of shoots and roots. Ten concentrations of each amino acid from 0.006 mM to 9.0 mM were tested under constant temperature conditions 20–22 °C/23–25 °C (night/day) an fluctuating stress of rising and dropping temperatures between 12–15 °C (night) and 30–38 °C (day). The amino acids were applied to the crop at growth stages V3–V4. In plants that were obtained from seeds pre-treated with L-Arg and Gly, the amino acids increased both the length of radicles and the number of lateral roots. A large discrepancy between the effects of the two amino acids was observed after foliar application. Under optimal thermal conditions, L-Arg increased the mass of shoots and roots by 55–59%. Under stress conditions, root mass was increased even by 100% when compared to the control plants. The best results were recorded at concentrations of 6 mM and 3 mM. Plants that were treated with Gly concentrations generally reached the height of untreated plants or less. It was shown that Gly applied at concentrations of 0.2 mM to 3 mM has a negative effect on the fresh mass of the crop.

The recent rapid rise of multi-drug resistant Enterobacteriaceae (MDR-E) is threatening the treatment of common infectious diseases. Infections with such strains lead to increased mortality and morbidity. Using a cross-sectional study, we aimed to estimate the prevalence of gut colonization with extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae among healthy infants born in Pakistan, a setting with high incidence of MDR-E infections. Stool samples were collected from 104 healthy infants between the ages of 5 and 7 months. Enterobacteriaceae isolates were screened for resistance against several antimicrobial classes. Presence of ESBL and carbapenemase genes was determined using multiplex PCR. Sequence types were assigned to individual strains by multi-locus sequence typing. Phylogenetic analysis of Escherichia coli was done using the triplex PCR method. Forty-three percent of the infants were positive for ESBL-producing Enterobacteriaceae, the majority of which were E. coli. We identified several different ESBL E. coli sequence types most of which belonged to the phylogenetic group B2 (23%) or D (73%). The widespread colonization of infants in a developing country with ESBL-producing Enterobacteriaceae is concerning. The multiple sequence types and reported non-human sources support that multiple non-epidemic MDR lineages are circulating in Pakistan with healthy infants as a common reservoir.

The efficacy of fluoroquinolone-based eradication therapy largely depends on the fluoroquinolone resistance of H. pylori. The aim of this study was to investigate the changes in the primary resistance rate of H. pylori to fluoroquinolone and the mechanism of resistance in Korea. A total of 153 strains and 48 strains of H. pylori were isolated at a tertiary hospital in 2005/2006 and 2017/2018, respectively. The minimum inhibitory concentrations (MICs) of fluoroquinolone were determined by the serial 2-fold agar dilution method. DNA sequences in the quinolone resistance-determining regions of gyrA/gyrB were analyzed in resistant strains. Subsequent natural transformation study was performed to determine the association between gyrase mutation and resistance. The resistance rates increased from 19.0% (29/153) to 43.8% (21/48) both for levofloxacin and moxifloxacin. The MIC values for resistant strains increased from 2–8 µg/mL to 4–16 µg/mL over time. Mutation of gyrA was detected in 93.1% (27/29) and 100% (21/21) among the resistant strains in both periods, respectively. A novel Gly-85 mutation of gyrA was found and confirmed to be associated with fluoroquinolone resistance. Fluoroquinolone resistance rate of H. pylori has markedly increased over time in Korea. The resistance is mostly due to the point mutation of gyrA. Fluoroquinolone-containing regimens should be carefully selected in Korea, considering the increasing fluoroquinolone resistance.

Despite limited indications, redundant anaerobic antimicrobial prescriptions (RAAPs) are frequent. The objective of this study was to assess the prevalence and characteristics of RAAPs in German acute care hospitals. In a retrospective data analysis, antimicrobial prescriptions from a point prevalence survey on antimicrobial use in German acute care hospitals in 2016 were analyzed and RAAPs were identified. RAAPs were defined as a patient simultaneously receiving any of the following combinations: Penicillin/beta-lactamase inhibitor (PenBLI) plus clindamycin; PenBLI plus metronidazole; PenBLI plus moxifloxacin; PenBLI plus carbapenem; carbapenem plus clindamycin; carbapenem plus metronidazole; carbapenem plus moxifloxacin; clindamycin plus metronidazole; clindamycin plus moxifloxacin; and metronidazole plus moxifloxacin. Data from 64,412 patients in 218 hospitals were included. Overall, 4486 patients (7%) received two or more antimicrobials. In total, 441 RAAP combinations were identified. PenBLI plus metronidazole was the most common anaerobic combination (N = 166, 38%). The majority of RAAPs were for the treatment of community-acquired (N = 258, 59%) infections. Lower respiratory tract infections (N = 77; 20%) and skin/soft tissue infections (N = 76; 20%) were the most frequently recorded types of infections. RAAPs are common in German hospitals. Reducing redundant antimicrobial coverage should be a key component of future antimicrobial stewardship activities.
