The potential use of Lentinus edodes to manage and control water hyacinth in Zimbabwe

The rapid expansion and reproduction of certain plant species represents one of the biggest problems in aquatic environments, ranging from eutrophication to the limited availability of water for human consumption. Among these plants is water hyacinth (Eichhornia crassipes), a herbaceous hydrophyte often branded the world’s worst aquatic weed due to its invasive aggression, negative impact on aquatic environments, and the cost usually associated with its management. Water hyacinth is a biomass, typically rich in lignocellulosic material and making it a potential raw material for the synthesis of products of industrial and domestic interest; e.g. edible fungi. Among the commonly known edible fungi is Lentinus edodes, a commercial mushroom whose versatile nature as a white rot fungus provides basis for the continued exploration of its biochemical processes during solid state fermentation on various lignocellulosic biomass as potential substrates. The fungus naturally feeds on lignocellulose by secreting various extracellular enzymes responsible for breaking down this organic polymer into simple soluble molecules that the hyphae can absorb and develop into mycelia. In this study, L. edodes was assessed for its ability to grow on water hyacinth and possibly utilizing it as a substrate. When cultured onto this noxious biomass followed by assessment by agar plate-based clearing assay and spectrophotometry, the fungus demonstrated its ability to secrete cellulases, xylanases, pectinases, peroxidases and laccases, thus showing its capabilities to physiologically utilize this hydrophyte as a substrate. If properly optimized, this approach can be remarkably used as a sustainable way to control water hyacinth in Zimbabwe. Key words: Lentinus edodes, water hyacinth, lignocellulosic biomass, lignocellulolytic enzymes, cellulases, xylanases, pectinases, lignin peroxidases, laccases.
A fully integrated EGS evaluation workflow

The development of an EGS is one of the goals of the GEMex project, an international collaboration of two consortia, one from Europe and one from Mexico. The research is based on exploration, characterization and assessment of two geothermal systems located in the Trans-Mexican volcanic belt, Los Humeros and Acoculco. Los Humeros has been a producing field for several years, but Acoculco is yet to be developed. Thanks to surface manifestations of hydrothermal activities, the existence of a geothermal system is evident. However, two wells reached very high temperatures, but did not find any fluids. For that reason, the Acoculco Caldera is foreseen as EGS development site, hoping to connect existing wells to a productive zone. In this study, we develop a workflow to assess the feasibility of this EGS. The approach aims at generating a realistic predictive mechanical model for fracture stimulation from the well borehole. The strength of the method stands in the combination of reliable data obtained from field work and experimental measurements on mechanical properties of the target rocks, used together to populate a numerical model. The workflow starts with the identification and description of the surface discontinuities using the scanline survey method. These surveys are interpolated and extrapolated using the multiple point statistics method to generate geological discrete fracture networks. These discrete fracture networks, together with the mechanical properties measured in the rock physics laboratory are then used to analyze the fracture propagation and its interaction with the pre-existing natural fractures. The results of the hydraulic fracture propagation simulations are then used in a finite element method program to evaluate the heat and fluid flow transfer, comparing reservoir properties before and after treatment. The method offers a physically sound prediction of the reservoir flow characteristics as well as an accurate mechanical model of the fracture propagation and the pressure distribution for well borehole stimulation. Because the workflow is based on easily accessible data and thanks to its simplicity, this approach could be applied in most EGS case studies.
SMALLSCALE FAMILY ENTREPRENEURSHIP AS SUPPORT TO THE NEOLIBERAL STATE IN POSTSOCIALIST SERBIA Sitno porodično preduzetništvo kao oslonac neoliberalnoj državi u postsocijalističkoj Srbiji

This paper points to the danger of the neoliberal instrumentalization of feminism in promoting family entrepreneurship as an emancipatory practice for women. It criticizes the key myths of neoliberal feminism about the freedom of choice that women have and their empowerment through family entrepreneurship. To that end, and through empirical research, it explores the benefits of women’s participation in the management of small-scale family entrepreneurship and business in 30 micro and small-sized firms in the traditional sectors, during the post-socialist transformation of Serbia. The aim of this article is to show that the process of women’s emancipation does not rest on these myths, but rather on the possibilities to change power structures based on the logic of capital and the neoliberal state in the semi-periphery of the world system, as well as the patriarchal gender regimes, that reproduce the strong subordination of women. The economic, social and moral benefits of entrepreneurship for women are debatable and limited by the interests of big capital and the neoliberal state. The possibilities of transforming gender relations through gender policies remain limited, because they do not derive from critically situated feminist discourse and do not correspond to the structural dispositions of a semi-peripheral economy and society like Serbia.
The Impact of Agricultural Market Information System in Bosnia & Herzegovina on MarketIntegration: Assymetric Information and Market Performance

When identical commodities are being exchanged between two or more markets, the prices of those commodities should be equal according to the law of one price, with the only difference in the transport cost between those markets. Therefore, in the perfectly integrated economy, local demand has no impact onto the formation of the market price, and once changes in local demand occur, the prices are being equalized in the national market through efficient allocation of resources (Pareto efficiency). Quantity supplied is being adjusted by shifting goods towards the markets with higher demand. This represents “the first fundamental theorem of welfare economics”, which is confirmation of Adam Smith's "invisible hand". The concept is further expanded first by Stigler, explaining the relevance of market information for the purpose of increasing market efficiency. When there is lacking significant market information, agents in the market cannot engage in optimal arbitrage and the price dispersion is present, so therefore markets are not efficient (Stigler, 1961). We put this theory into perspective of the particular setting in B&H. We analysethe extent of agro-food market integration in B&H by studying price differentials between different market locations to answer whether the introduction of ICT service improved market efficiency, thereby potentially revealing that actors in the market did not actually have access to relevant price information.
The Age of Immanence: Postoperaismo, Postcapitalism and the Forces and Relations of Production

This working paper relates the movement between Marx and Spinoza in the postoperaismo of Antonio Negri to its subsequent reception on the contemporary left via the intellectual regeneration offered by postcapitalist and ‘post-work’ thinking. The latter, we argue, translates Negri's Spinozism into a hopeful assessment of political possibility not reflected in preset conditions. In postoperaismo, and in particular the turn to Spinoza in the work of Negri, key categories of Marx’s critique of political economy are reevaluated in line with a utopian analysis of the potentialities of contemporary capitalism and its immanent tendency towards a postcapitalist transformation. Through a close reading of Negri’s three translated books and collections dealing with Spinoza, the paper critiques the underlying ideas and consequences of this appraisal. In so doing it is informed by a countervailing appreciation of value, labour and class in capitalist society grounded in the ‘critique of political economy as a critical social theory’ approach. The working paper argues that Negri, owing to his positing of Spinozian plane of immanence of which all social principles are an ontologically equivalent part, essentially ends up at a conservative position that takes the world as it is, and reflects it back on itself. A political vision based around the immanent power of the multitude, constrained only by limits of its own self-valorising creation, possesses intellectual resources only for a very passive form of resistance which merely affirms capitalist development. From unorthodox beginnings, Negri’s worldview ends up little different to the most crudely deterministic historical materialism, paradoxically combining resigned quietism with revolutionary overoptimism. The wrong kinds of theory impoverish the critical resources undergirding political praxis, and Negri’s ideas, whilst innocuous in and of themselves, cascade through contemporary left politics. His celebratory account of societal and technological change is carried over in the left ‘accelerationism’, ‘postcapitalism’ and ‘Fully Automated Luxury Communism’ discussed in the concluding section of this paper. It is suggested that the development of an alternative to technological utopianism is a necessary step for left renewal following the defeat of Corbynism and the failure of a policy agenda inspired in part by the worldview surveyed here.
Gender Disparity Signals : Analyzing gender disparities with mobile phone metadata

Ending gender discrimination in all its forms has long been a sustainable development goal of the United Nations. Despite initiatives and efforts of different governments across the world, however, gender discrimination still exists. One of the biggest problems has been the lack of accurate information about gender disparity. This project aims at modeling educational gender disparity at the district level in Pakistan using network data extracted from call detail records. Using survey-based educational gender disparity as ground truth data, we first explore the prominent network metrics and patterns that help in better understanding of gender disparities in the population. In the second half of this project, we use these network metrics to predict educational gender disparity at the district level.
SUPPLEMENTARY MATERIALS: Threshold uncertainty, early-warning signals, and the prevention of dangerous climate change

Hurlstone and Newell1 experimentally examined whether early-warning signals of approaching climate thresholds could overturn the impediment of threshold uncertainty on cooperation in a catastrophe avoidance threshold public goods game. They showed that large initial—and subsequently unabated—threshold uncertainty undermines cooperation, consistent with earlier studies,2–4 but additionally that a marked subsequent reduction in threshold uncertainty— mimicking an early-warning signal—does little to improve the prospects of cooperation. The findings suggest that early-warning signals indicating that a critical climate threshold is approaching are unlikely to offer the leverage necessary to motivate countries to take the necessary action to avert catastrophe. This supplementary document reports additional details about the study including an extended literature review; the instructions given to participants; and ancillary statistical analyses. Note that this document is not meant to be self-explanatory—please consult Hurlstone and Newell1 for further information.
EXPERIMENTAL VALIDATION OF STABLE OBSTACLE CLIMBING WITH A FOUR-WHEEL MOBILE ROBOT OpenWHEEL i 3 R

This paper describes the experimental validation for stable climbing of an obstacle such as a step with a mobile robot that has only four wheels. The robot structure OpenWHEEL i3R is described, with two axles linked by a 3R intermediate serial mechanism. The climbing process is the interpolation between a series of poses where static stability is guaranteed. Experiments are performed on a reduced scale model including five actuators. The comparison of the real behavior of the robot with the simplified bi-dimensional model initially used brings results to improve design and control of the robot, particularly stability margin and wheel adherence. Conclusions are drawn about this new climbing mode and future work is traced for an improved control.
AI FOR BETTER STORYTELLING IN LIVE FOOTBALL

Artificial Intelligence (AI) represents almost limitless possibilities for the future and is already having a transformational impact in many areas. Live football production is one where there is a real need to drive operational efficiencies as rights holders are pushed to deliver more and better live content to an increasingly diverse and connected audience. With the right machine learning agents in place, AI is able to mimic creative human behaviour, overcoming the limitations of automation and performing high-level, complex tasks with the speed and reliability that is required in live environments. In this paper, we will present our vision of AI as a built-in production assistant, through some potential future applications as well as current use cases in the context of live football storytelling. We will showcase applications such as assisted framing, camera selection, camera calibration and automatic robotic camera steering that all contribute to delivering better storytelling in live sport productions
Platform-Merchant Competition for Selling Services

In this paper, we study whether a monopolistic platform prefers to impose price parity when it competes with merchants for selling services. The platform and the direct sales channel are differentiated in quality on the consumer side and in terms of efficiency. We show that the platform imposes price parity when it is highly differentiated in quality on the consumer side and that this restriction lowers the total transaction fee paid by consumers and merchants. Price parity increases the total buying price of consumers who buy from merchants who receive high benefits of selling on<br>the platform and decreases it otherwise.
ROMANIAN VERBS OF EMISSION

This paper aims to bring some clarifications regarding Romanian verbs of emission. On the one hand, we provide a classification of these verbs, following the semantic classification in Levin and Rappaport Hovav (1995). On the other hand, we bring morphological and syntactic arguments for the unergative status of verbs of emission. Thus, not only are these verbs not derived with the prepositional prefix în-, but, more importantly, they do not show the reflexive clitic pronoun se present with most Romanian unaccusatives. Moreover, some verbs of emission show the Agent-Instrument pattern, a blueprint of unergativity (cf. Potashnik 2009).
Applying An Eye-Tracker To Study Effects Of Using Human Presenter In Product Image

This study applies an eye-tracker to investigate effects of using human presenter in product images. Fixation duration of five different product images on e-commerce webpages were collected using Mirametrix S2 Eye Tracker. The five different product images are [2] using no human presenter in product image, [1] using male presenter with positive emotion (smiling face) in product image, [3] using male presenter with neutral emotion in product image, [4] using female presenter with positive emotion (smiling face) in product image, and [6] using female presenter with neutral emotion in product image. This study was conducted in a laboratory. The data was collected from 100 undergraduate students from Chulalongkorn Business School, Thailand. The result indicates that product image with positive emotion female presenter gets the highest fixation duration, however, not significantly higher than fixation duration of other types of product images.
ICPE 2018

The article presents a review aimed at studying the relationship between the process quality of the educational environment and the indicators of preschool language development. By process quality is understood the quality of the processes of teacher-child interaction in kindergarten groups (the CLASSTM assessment). The review considers correlation and longitudinal studies. The analysis and systematization of research results is carried out separately for the CLASSTM domains: Instructional Support, Emotional Support and Classroom Organization, which correspond to the emotional, instructional and organizational aspects of teacher-child interactions. The results of the studies testify to the existence of a stable connection between the organizational features of teacher-child interactions and their results of language development. The high level of consistency in the research results testifies to the effectiveness of the method used to assess the process quality of the educational environment the Classroom Assessment Scoring System (CLASSTM) and the significant effect of process quality on preschool language development. This review can be useful for researchers of the quality of preschool education, since it presents systematic results of studies and information on the effectiveness of methods used in them. © 2018 Published by Future Academy www.FutureAcademy. org.UK
Prevalence of Depression among the Farmers and its Determinants: A Cross Sectional Study

Context: India being an agrarian country, where agriculture plays a vital role in ensuring food security and poverty alleviation. Farmers who are completely involved in agriculture face a number of unique occupational stressors such as physical environment, family structure, farm economy. These stressors have resulted in various psychiatric disorders such as depression, anxiety resulting in high rates of suicides among farmers.
Wide load range resonant converter supplying the SAE J-1773 inductive charging interface

The recommended practice for electric vehicle battery charging using inductive coupling (SAE J-1773), published in January 1995 by the Society of Automotive Engineers, Inc. (SAE), outlines values and tolerances for critical vehicle inlet parameters which must be considered when selecting a driving topology. The inductive coupling vehicle inlet contains a significant discrete capacitive component in addition to low magnetizing and high leakage inductances. Driving the topology with a variable-frequency, series-resonant converter results in a four-element topology with many desirable features: unity transformer turns ratio; buck-boost voltage gain; current source operation; monotonic power transfer characteristic over a wide load range; throttling capability down to no-load; high-frequency operation; narrow frequency range; use of zero-voltage-switched MOSFETs with slow integral diode; high efficiency; inherent short-circuit protection; secondary dv/dt control and current waveshaping for the cable, coupler and vehicle inlet resulting in enhanced electromagnetic compatibility.
Structural Complexity Evolution in Free Software Projects: A Case Study

While Free Software projects do have quality assurance activities, there is still room for improvement and introduction of new methods and tools. This paper presents a case study of structural complexity evolution in a small project written in C. The approach used can be used by Free Software developers in their own projects to understand and control complexity, and the results provide initial understanding on the study of structural complexity evolution
Towards a Connectionist Model for Minimalist Syntax

Many neuroscientists, linguists and computer scientists attempt to unravel the secret of language. Most (though certainly not all) do so in relative independence, with their own means. The goal of this paper is to show how combining the three perspectives may help in making conceptual decisions in linguistics, designing neuroscientific experiments and developing an artificial language system. I do not mean to deny the great value of the findings in each field separately, and the interdisciplinary approach employed here is only able to touch on each subject from the outside. But I feel that it is a valuable, clarifying touch. The strategy employed here will be as follows. I will formulate linguistic key elements in terms of connectionist mechanisms, derived from findings in computer science. During this translation process, I will relate decisions to neuroscientific data. The linguistic framework employed here will be the Minimalist Program. Its defining characteristic is the goal to remove all unnecessary theoretical artifacts and reduce the conceptual machinery to (ideally) the pure necessities. In this sense, the Minimalist Program is more fit than any other linguistic framework for the goal of this paper. A choice between two mutually exclusive views in the Minimalist Program is first made in section 2. Further specifics of the Minimalist Program will be reviewed in section 4. The influence of computer science in this paper is apparent mainly in my decision to assume a synchrony-based encoding underlying the language faculty. Neuroscience is not yet fully able to actually destill from brain-imaging data the proof for a synchrony-based encoding, but certain findings, for instance on brain waves, do hint in this direction. Synchrony-based encoding is explained in section 3. My usage of this connectionist mechanism is based mainly on the dissertation of Makino ([16]) and earlier work by Henderson ([10]), although it differs in some important respects. The Minimalist Program is just that: a program. It is not, and does not claim to be, a complete theory of language. There are many contradictory views within the Minimalist Program, and many open questions exist. This makes it difficult to isolate the key elements, and throughout this paper decisions will have to be made regarding which theory of language to pursue. These decisions
Analyzing the Important Factors for Cloud Service Provider Selection among the IT firms in Turkey

Cloud computing, as being one of the trendy topics, provides mechanisms for the companies to meet all the information technology and management requirements at a desired performance level with reduced upfront investments. From the economical perspective, it creates a positive impact by helping them focus on their own business. With this positive impact, it causes a huge increase on the number of user firms, and many service providers try to provide solutions based on the user firms’ needs. There are studies on identifying the factors that are used in selecting cloud service solutions in the literature. Having examined the pivotal points among the Information Technology (IT) sector in Turkey, we conducted a survey among the managers of various firms to gather information about their cloud service provider and the factors that provision their choice. Since that decision is very strategic, and once decided it is very hard to alter, it is worth analyzing the set of factors that are used in the survey further in order to identify the most important ones and help new companies for their selection. We provide statistical evaluations based on the results of the survey in this study.
