Schema matching
is a process that serves in integrating structured and semi-structured data. Being a handy tool in multiple contemporary business and commerce applications, it has been investigated in the fields of databases, AI, Semantic Web, and data mining for many years. The core challenge still remains the ability to create quality algorithmic matchers, automatic tools for identifying correspondences among data concepts (
e.g.
, database attributes). In this work, we offer a novel post processing step to schema matching that improves the final matching outcome without human intervention. We present a new mechanism,
similarity matrix adjustment
, to calibrate a matching result and propose an algorithm (dubbed ADnEV) that manipulates, using deep neural networks, similarity matrices, created by state-of-the-art algorithmic matchers. ADnEV learns two models that iteratively adjust and evaluate the original similarity matrix. We empirically demonstrate the effectiveness of the proposed algorithmic solution for improving matching results, using real-world benchmark ontology and schema sets. We show that ADnEV can generalize into new domains without the need to learn the domain terminology, thus allowing cross-domain learning. We also show ADnEV to be a powerful tool in handling schemata which matching is particularly challenging. Finally, we show the benefit of using ADnEV in a related integration task of ontology alignment.
Scalable, near-zero loss disaster recovery for distributed data stores
Authors: Alquraan Ahmed , Kogan Alex , Marathe Virendra J. , Al-Kiswany Samer
Published: June 2020

This paper presents a new Disaster Recovery (DR) system, called Slogger, that differs from prior works in two principle ways: (i) Slogger enables DR for a
linearizable
distributed data store, and (ii) Slogger adopts the
continuous backup
approach that strives to maintain a tiny lag on the backup site relative to the primary site, thereby restricting the data loss window, due to disasters, to milliseconds. These goals pose a significant set of challenges related to consistency of the backup site's state, failures, and scalability. Slogger employs a combination of asynchronous log replication, intra-data center synchronized clocks, pipelining, batching, and a novel
watermark service
to address these challenges. Furthermore, Slogger is designed to be deployable as an "add-on" module in an existing distributed data store with few modifications to the original code base. Our evaluation, conducted on Slogger extensions to a 32-sharded version of LogCabin, an open source key-value store, shows that Slogger maintains a very small data loss window of 14.2 milliseconds which is near the optimal value in our evaluation setup. Moreover, Slogger reduces the length of the data loss window by 50% compared to incremental snapshotting technique without having any performance penalty on the primary data store. Furthermore, our experiments demonstrate that Slogger achieves our other goals of scalability, fault tolerance, and efficient failover to the backup data store when a disaster is declared at the primary data store.

Published: June 2020

Finding a set of users of interest serves several applications in behavioral analytics. Often times, identifying users requires to explore the data and gradually choose potential targets. This is a special case of Exploratory Data Analysis (EDA), an iterative and tedious process. In this paper, we formalize and solve the problem of guided exploration of user groups whose purpose is to find target users. We model exploration as an iterative decision-making process, where an agent is shown a set of groups, chooses users from those groups, and selects the best action to move to the next step. To solve our problem, we apply reinforcement learning to discover an efficient exploration strategy from a simulated agent experience, and propose to use the learned strategy to recommend an exploration policy that can be applied to the same task for any dataset. Our framework accepts a wide class of exploration actions and does not need to gather exploration logs. Our experiments show that the agent naturally captures manual exploration by human analysts, and succeeds to learn an interpretable and transferable exploration policy.

Authors: Metwali Mohamed M. A.
Published: June 2020

The existence of a.e. monotonic solutions for functional quadratic Hammerstein integral equations with the perturbation term is discussed in Orlicz spaces. We utilize the strategy of measure of noncompactness related to the Darbo fixed point principle. As an application, we discuss the presence of solution of the initial value problem with nonlocal conditions.
90 YEARS OF PROGESTERONE: New insights into progesterone receptor signaling in the endometrium required for embryo implantation
Authors: DeMayo Francesco J , Lydon John P
Published: June 2020

Progesterone’s ability to maintain pregnancy in eutherian mammals highlighted this steroid as the ‘hormone of pregnancy’. It was the unique ‘pro-gestational’ bioactivity of progesterone that enabled eventual purification of this ovarian steroid to crystalline form by Willard Myron Allen in the early 1930s. While a functional connection between normal progesterone responses (’progestational proliferation’) of the uterus with the maintenance of pregnancy was quickly appreciated, an understanding of progesterone’s involvement in the early stages of pregnancy establishment was comparatively less well understood. With the aforementioned as historical backdrop, this review focuses on a selection of key advances in our understanding of the molecular mechanisms by which progesterone, through its nuclear receptor (the progesterone receptor), drives the development of endometrial receptivity, a transient uterine state that allows for embryo implantation and the establishment of pregnancy. Highlighted in this review are the significant contributions of advanced mouse engineering and genome-wide transcriptomic and cistromic analytics which reveal the pivotal molecular mediators and modifiers that are essential to progesterone-dependent endometrial receptivity and decidualization. With a clearer understanding of the molecular landscape that underpins uterine responsiveness to progesterone during the periimplantation period, we predict that common gynecologic morbidities due to abnormal progesterone responsiveness will be more effectively diagnosed and/or treated in the future.
90 YEARS OF PROGESTERONE: Selective progesterone receptor modulators in gynaecological therapies
Authors: Critchley H O D , Chodankar R R
Published: June 2020

Abnormal uterine bleeding (AUB) is a chronic, debilitating and common condition affecting one in four women of reproductive age. Current treatments (conservative, medical and surgical) may be unsuitable, poorly tolerated or may result in loss of fertility. Selective progesterone receptor modulators (SPRMs) influence progesterone-regulated pathways, a hormone critical to female reproductive health and disease; therefore, SPRMs hold great potential in fulfilling an unmet need in managing gynaecological disorders. SPRMs in current clinical use include RU486 (mifepristone), which is licensed for pregnancy interruption, and CDB-2914 (ulipristal acetate), licensed for managing AUB in women with leiomyomas and in a higher dose as an emergency contraceptive. In this article, we explore the clinical journey of SPRMs and the need for further interrogation of this class of drugs with the ultimate goal of improving women’s quality of life.

Published: June 2020

In this paper we continue to investigate the properties of the problem with nonlocal conditions, which are multipoint perturbations of mixed boundary conditions, started in the first part. In particular, we construct a generalized transform operator, which maps the solutions of the self-adjoint boundary-value problem with mixed boundary conditions to the solutions of the investigated multipoint problem. The system of root functions $V(L)$ of operator $L$ for multipoint problem is constructed. The conditions under which the system $V(L)$ is complete and minimal, and the conditions under which it is the Riesz basis are determined. In the case of an elliptic equation the conditions of existence and uniqueness of the solution for the problem are established.
Cécités et créations
Authors: Arentsen Maria Fernanda , Thompson Hannah
Published: June 2020

Ce numéro spécial interroge et affirme les liens productifs et innovateurs qui existent entre cécité et création. Nous réunissons ici des réflexions historiques, créatives et littéraires qui montrent, de manière pluridisciplinaire, que de nouvelles conceptions de la cécité peuvent briser les images stéréotypées de la personne aveugle qui hantent la société contemporaine. Nous rejetons le modèle médical de la cécité qui représente la personne aveugle comme victime ou objet de pitié souffrant de son sort. Tout en reconnaissant les inconvénients qu’affrontent les personnes aveugles dans un monde fait pour et par les personnes non aveugles, nous affirmons que la cécité n’est ni problème ni tragédie. Au contraire, elle ouvre de nouvelles perspectives intellectuelles, imaginatives, esthétiques et innovatrices qui remettent en question la position privilégiée de la vue dans la hiérarchie des sens.
Adaptive Musical Instruments (AMIs): Past, Present, and Future Research Directions
Authors: Grond Florian , Shikako-Thomas Keiko , Lewis Eric
Published: June 2020

We review and discuss the literature related to adaptive musical instruments since 2000, focusing on the use of such instruments with children with disabilities. The aim of this review is to provide a synthesis of perspectives and answer the following questions: How have music technologies, including both software and hardware, been used for children with disabilities and how have they been tested and evaluated? What have been the research questions asked and outcomes evaluated concerning these instruments? The studies reviewed include intervention, narrative and descriptive studies. One observation is that adaptive instrument design and research cuts across many different disciplines including music therapy, education and engineering. We considered articles taking functional and rehabilitation informed perspectives as well as critical disability studies, for which music making is often discussed as a human right independently of potential benefits. We discuss methodological approaches used in these studies, and reports of user’s opinions concerning the use of AMIs. It is worth noting that most uses of AMIs by the population under consideration are highly improvisatory, and so a methodological challenge frequently reported is how can the effectiveness of AMIs be assessed without focusing only on easily measurable outputs? We reveal divisions existing between research focusing on the use of AMIs with precise therapeutic and pedagogic goals in mind, and that interested in more general positive effects of improvised collective creative activity and its role in community building. With this two-fold perspective, we analyse the limitations of current research and derive questions for future directions.
“Hap Walk”: A Reading of Living a Feminist Life by Sara Ahmed and “Docile Bodies” in Discipline and Punish by Michel Foucault
Authors: Ki Patricia
Published: June 2020

This paper grew from the imagining that Sara Ahmed and Michel Foucault, both influential scholars in my ever-developing understanding of the world, met face-to-face one ordinary day, discussed their ideas, responded to each other’s queries, reflected on historical and ongoing social injustices, and shared hopeful imaginings for the future. In this imaginary account, through the form of dialogues, I compare, contrast, and examine concepts in Foucault’s and Ahmed’s works—specifically, the chapter “Docile Bodies” in Discipline and Punish, published in 1977, and the book Living a Feminist Life, published 40 years later in 2017.1 Following Ahmed, I use path, walls, and tables as both metaphors and material effects of disciplinary power to link theorizations from the two texts regarding the embodiment of discipline, through which white, capitalist, and heteropatriarchal norms persist. Further, I ask questions of Foucault’s text about the seeming invisibility of women and disabled people in its discussion of docile bodies and disciplinary power and echo other feminist scholars in arguing that it is through the perspectives and experiences of those who have been cast out of belonging and rendered invisible that we may find the means to expose the most cemented and hidden structures and techniques of domination and to imagine forms of resistance and subversions that point to a different future. For the purpose of clarity, direct quotes from Ahmed’s and Foucault’s texts are italicized within the dialogues, accompanied by in-text citations.
Colonialismo: un episodio en la historia africana
Authors: Ajayi J. F. Ade , Campos Serrano Alicia
Published: June 2020

En 1969 la descolonización era un proceso en curso que ya había dado lugar a numerosos estados independientes. Y jóvenes historiadores, fuera y dentro del continente, trabajaban con entusiasmo por ofrecer una "historia africana" alejada de los presupuestos hegelianos y eurocéntricos que habían negado, en las décadas anteriores, la historicididad de las poblaciones al sur del Sáhara. Eran tiempos de "construcción de naciones", y había que proporcionar historias donde los africanos paarecieran como protagonistas, hacedores de estados y sistemas comerciales, y no como meras víctimas o elementos del paisaje.
Factors Associated with Depression in Middle-Aged and Elderly People in Romania
Authors: Rada Cornelia
Published: June 2020

The objectives of this study were the determination of the prevalence of self-reported depressive symptoms by the Geriatric Depression Scale and the influences of variable income, physical activity, socialization and sexual activity. A total of 601 patients aged 55–93 years with a mean age of 67.32 years and a median age of 67 years participated in this study between 2016 and 2017. Non-cooperative people and individuals with strong auditory or visual sensory deficits, severe cognitive deficits, or disorders accompanied by psychotic elements with serious somatic pathology were excluded from the interviews. Employing the SPSS GENLIN procedure, an ordinal logistic model was used. Over ½ of the respondents are within the categories of moderate and severe depression, almost half of the respondents feel that their family incomes are not enough or make it hard to meet their needs, approximately 10% think they are sedentary, over ½ participate in no sexual activity, and over ¼ do not frequently respond with pleasure to partner-initiated sexual relationships. Those who were in the higher depression category perceived their income to be extremely low (p = .001), perceived themselves as sedentary (p < .001), infrequently met with friends or neighbours in their leisure time (p = .002), and had lower sexual interest (p < .001). Middle-aged adults and older adults should learn about the health benefits of physical activity, socialization and sexual activity. Social policies must take into account this low-income segment. Poverty itself can be a contributor to depressive states, and additionally, due to their low incomes, elderly people are at risk of benefiting less from pharmacotherapy and psychotherapy.

Published: June 2020

Background and Study Aim: Electromyostimulaiton (EMS) has been used for both physical therapy and strength improvements for a few decades. This study aimed to investigate the effects of a four-week local-EMS training performed on a fingerboard (FT) in wrist strength and endurance.
Material and Methods:  Sixteen physically active, non-climber students were divided into EMS+FT and FT groups. Each group performed the same training program about 25 min a day, 3 days a week for four weeks. The EMS+FT implementation was performed with a signal width of 260 ms and a frequency of 60 Hz. Before and after training, isokinetic measurements were collected. The parameters used in the research during flexion and extension at 60 and 180°/sec were; Peak Torque (PT), Peak Torque/Body Weight (PT/BW), and Average Power (AP).
Results: The EMS+FT group showed statistically significant alterations in all of the parameters (p<0.01 and p<0.05) except in the left wrist AP during flexion and extension at 180°/sec. However, the FT group showed significant changes in only wright wrist AP during extension at 60°/sec, and wright and left wrist AP during flexion at 180°/sec, and left wrist PT during extension at 180°/sec.
Conclusions: Accordingly, it could be inferred that FT done by using EMS for four weeks improve the isokinetic wrist strength and endurance significantly. Muscular fitness has an essential role in climbing performance, and this study points that EMS trainings on fingerboard could be used to enhance the climbing performance.

Published: June 2020

The purpose of this study is to determine the construction of the meaning of Sunda Wiwitan religion in Sundanese Baduy indigenous people. The research uses interpretive paradigms with qualitative methods, and symbolic interaction study approaches as a tool of analysis. Data gathered through participatory observation and in-depth interviews. Sunda Wiwitan religion is the main symbol in the Baduy indigenous people, and is a dimension that reaches every side of life, and is a collective representation of the belief system of the Baduy indigenous community. This symbol serves as a reference for the collective paradigm, and as a reference for interpreting natural phenomena and determining the behavior of the Baduy indigenous people. The symbol of traditional institutions and traditional ceremonies represent three essential issues, namely: (1) Understanding and appreciation of religion (belief) of the Baduy indigenous people as Sunda Wiwitan descendants; (2) Observance and practice of the daily life of the Baduy indigenous people as members of the traditional Sundanese or Sunda Buhun social groups; and (3) Symbolization of the existence and recognition of the existence of government and power outside the Baduy Customary institution.
Optimal Solar Panel Area Computation and Temperature Tracking for a CubeSat System using Model Predictive Control
Authors: Al-Hemeary Nawar , Polcz Péter , Szederkényi Gábor
Published: June 2020

Recently, there has been a rising interest in small satellites such as CubeSats in the aerospace community due to their small size and cost-effective operation. It is challenging to ensure precision performance for satellites with minimum cost and energy consumption. To support maneuverability, the CubeSat is equipped with a propellant tank, in which the fuel must be maintained in the appropriate temperature range. Simultaneously, the energy production should be maximized, such that the other components of the satellite are not overheated. To meet the technological requirements, we propose a multicriteria optimal control design using a nonlinear dynamical thermal model of the CubeSat system. First, a PID control scheme with an anti-windup compensation is employed to evaluate the minimum heat flux necessary to keep the propellant tank at a given reference temperature. Secondly, a linearization-based controller is designed for temperature control. Thirdly, the optimization of the solar cell area and constrained temperature control is solved as an integrated nonlinear model predictive control problem using the quasilinear parameter varying form of the state equations. Several simulation scenarios for different power limits and solar cell coverage cases are shown to illustrate the trade-offs in control design and to show the applicability of the approach.
Automated Search for Locations of Detention Groups to Reduce Security Activity Risk
Authors: Pyankov Oleg , Smyshnikov Dmitry
Published: June 2020

Property security management is a crucial problem in keeping tangible and intangible assets safe. Its solution using technical means and mobile detention groups ensures assets preservation and reduces security activities risk. Classical definition of a risk, which relates the probability of damage to the protected object to the amount of damage, is proposed to use. For determining the probability, an assumption, where only arrival time of the detention group at secured facility is recorded by the alarm signal, is introduced.

In order to minimize the total risk of security activities the task of finding the location of the detention group on the ground with dispersed objects is formulated. As a solution to the formulated problem, a search for the location of the detention groups which takes into account the magnitude of the damage and the current coordinates of the object on the plane is proposed. Examples of calculating locations of detention groups on the plane are presented.

An objective function Ф of the effectiveness of security activities implementation, linking the financial and economic indicators of security organization with the value of security activities risk is introduced and substantiated. The analysis of function Φ behavior with a change in the number of detention groups is shown, the presence of function extremum is shown, the interval of finding the extremum is determined.

It is proposed to calculate the distances between objects on a map and to use it to determine the coordinates in a new auxiliary plane. Coordinates are calculated using Gram matrices. A computational example is presented.

A step-by-step algorithm for secured facility allocation between detention groups with minimization of the total risk of security activities is developed; an example of its use is presented.

A search procedure for the location of the detention group on the ground by the determined coordinates on the plane is defined; a search process is illustrated. A general location search algorithm is proposed and the results are presented.
Two-Module Weight-Based Sum Code in Residue Ring Modulo M=4
Authors: Efanov Dmitry , Sapozhnikov Valery , Sapozhnikov Vladimir
Published: June 2020

The paper describes research results of features of error detection in data vectors by sum codes. The task is relevant in this setting, first of all, for the use of sum codes in the implementation of the checkable discrete systems and the technical means for the diagnosis of their components. Methods for sum codes constructing are described. A brief overview in the field of methods for sum codes constructing is provided. The article highlights codes for which the values of all data bits are taken into account once by the operations of summing their values or the values of the weight coefficients of the bits during the formation of the check vector. The paper also highlights codes that are formed when the data vectors are initially divided into subsets, in particular, into two subsets. An extension of the sum code class obtained by isolating two independent parts in the data vectors, as well as weighting the bits of the data vectors at the stage of code construction, is proposed.

The paper provides a generalized algorithm for two-module weighted codes construction, and describes their features obtained by weighing with non-ones weight coefficients for one of data bits in each of the subvectors, according to which the total weight is calculated. Particular attention is paid to the two-module weight-based sum code, for which the total weight of the data vector in the residue ring modulo M = 4 is determined. It is shown that the purpose of the inequality between the bits of the data vector in some cases gives improvements in the error detection characteristics compared to the well-known two-module codes. Some modifications of the proposed two-module weighted codes are described. A method for calculating the total number of undetectable errors in the two-module sum codes in the residue ring modulo M = 4 with one weighted bit in each of the subsets is proposed. Detailed characteristics of error detection by the considered codes both by the multiplicities of undetectable errors and by their types (unidirectional, symmetrical and asymmetrical errors) are given. The proposed codes are compared with known codes. A method for the synthesis of two-module sum encoders on a standard element base of the single signals adders is proposed. The classification of two-module sum codes is presented.

Published: June 2020

This article was migrated. The article was not marked as recommended. Introduction: It is important for nurse educators to evaluate the teaching performance of nurse preceptors related to these workplace-based assessment tools. The objective structured teaching evaluation was developed to evaluate teaching performance. However, limited attention has been given to the relationship between the use of these workplace-based assessment tools and previous OSTE training. Hence, this study is to investigate the relationship between the teaching behaviors of nurse preceptors and previous objective structured teaching evaluation (OSTE) training. Methods: This cross-sectional study recruited 42 N3-level nurse preceptors who had completed previous OSTE training at a medical teaching hospital in central Taiwan. Demographics, teaching behaviors, and OSTE-related variables of the participants were assessed using a questionnaire. Results: For assessment tools, 90.6% of the nurse preceptors used direct observations of procedural skills (DOPS), 59.4% used mini-clinical evaluation exercises (mini-CEX), and 40.6% used case-based discussions (CBD). The sandwich feedback technique was used for clinical teaching evaluations. Shown out of the passing score, the mean scores of the nurse preceptors for each OSTE station were 82.9/66.8 for DOPS, 71.0/73.3 for mini-CEX, and 69.4/71.5 points for CBD. The use of all three assessment tools was correlated with use of the sandwich feedback technique (r = 0.94-1, p < 0.01). The OSTE scores were not correlated with teaching behaviors (r = −0.06-0.25, p > 0.01). Conclusions: Nurse preceptors exhibited good teaching behaviors, using workplace-based assessment tools and the sandwich feedback technique. Clinical teaching behaviors may be more dependent on hospital teaching policies than on previous OSTE training scores.
Interconnection of functional subsystems of corporate governance
Authors: Sharokhina Svetlana , Pudovkina Olga
Published: June 2020

The article discusses the features of corporate governance associated with the distribution of ownership and management functions. The components of corporate governance elements are considered in two directions: from the standpoint of the requirements of the current law; from the position of identifying corporate governance with the overall management system in the enterprise. The necessity of applying a systematic approach to the allocation of management functions is justified and their relationship in the corporate governance system is determined. The authors argue that in analyzing corporate governance, one cannot identify it with the enterprise management system in general and exclude the influence of owners on the corporate governance process. The authors propose from the set of corporate governance functions called the following list of functions arranged according to their priority, ambiguity, essence: planning, organization, accounting, control, analysis, regulation. The article describes the goals of implementing individual corporate governance functions and outlines the relationship of some functions with others. The authors call the features of the implementation of the analytical function associated with the opposite of interests. So, if for the management of the company carrying out analytical calculations should contribute to the scientific justification of management decisions, then carrying out analytical calculations by owners is most often aimed at assessing the effectiveness of the enterprise through the activities of management personnel. It is substantiated that the need to study the analytical subsystem, taking into account the requirements of a system-functional approach, is dictated by the fact that it is a subsystem in the general corporate management system, which has an informational relationship with other functional subsystems and is implemented both by the owners and the management of the enterprise.
In the course of the study, it was found that the main feature of corporate governance is associated with the distribution of the overall management system between the enterprise management and its owners. At the same time, certain functions are implemented only by certain corporate governance bodies, while others are inherent to both owners and management.

Published: June 2020

ABSTRACT Introduction: Narcolepsy patients have higher prevalence of comorbidities, such as obesity, depression, and pain. Narcolepsy symptoms and concomitant medical conditions can impact the daily activities of patients. The objective of this study is to describe the quality of life in a sample of patients with narcolepsy, and the influence of the nutritional status in health domains. Methods: At Unifesp, two groups of 33 patients (narcolepsy types 1 and 2 meeting 2014 criteria, concerning hypocretin-1) and 33 controls without sleepiness, matched by age and sex, filled out the SF-36. Results: Narcolepsy groups, regardless of their nutritional status, had significantly lower scores in all domains, compared to controls, mainly in Role-physical, Role-emotional, and Energy/Fatigue. Role-physical score was lower in type 1 than in type 2 and controls (37.8±1.0 vs. 50.0±1.2 vs. 85.6±1.6; p<0.0001). Obese with type 2 narcolepsy scored lower than type 1 in physical scales. Conclusion: In a Sleep Center in São Paulo, Brazil, physical and mental health were impaired in narcolepsy types 1 and 2. The first report of the poor health status in Brazilians with narcolepsy type 2 suggests that obesity negatively affects physical domains.

Published: June 2020

ABSTRACT The objective of this study was to determine the effective hydraulic conductivity of six areas located in the Cerrado region of Mato Grosso, Brazil, and to identify physical attributes of soils with potential for predicting effective hydraulic conductivity. The tests to determine the effective hydraulic conductivity were carried out in six areas, covering the textural classes sand, sandy loam and clay, and the following uses: pasture, Cerrado and agriculture. Particle size, sand fractionation, total carbon content, degree of clay flocculation, bulk density, macroporosity, microporosity, mean weight diameter, mean geometric diameter and aggregate stability index were determined. From the data, statistical analyses of contrasts were performed by the Kruskal - Wallis test, and simple Pearson’s correlation coefficient was determined between variables. The average values of effective hydraulic conductivity for the pasture, agriculture and Cerrado areas were 95.73, 27.83 and 48.31 mm h-1, respectively. Higher value of effective hydraulic conductivity was observed in the Pasture area point 2 when compared to the Agriculture area point 2, because the amount of clay determined in Agriculture area was approximately 16 times greater than that of the area Pasture point 2, conditioning lower water infiltration in the soil profile of the area Agriculture point 2. Among the physical attributes analyzed, those with the highest potential for Ke prediction were: clay, silt, sand (coarse, medium and fine), total carbon and aggregate stability index.

ABSTRACT The objective of this study was to evaluate the uniformity of distribution in drip units applying dilutions of treated water produced by oil exploration. The experiment was set up in a completely randomized design in a split-split-plot scheme, with three replicates. The plots were composed of the treatments P0 - 100% groundwater, control; P10 - 90% groundwater and 10% produced water; P20 - 80% groundwater and 20% produced water; P30 - 70% groundwater and 30% produced water; and P40 - 60% groundwater and 40% produced water; the subplots had the types of non-pressure compensating drippers (D1 - 1.6 L h-1, Netafim Super Typhoon, D2 - 1.6 L h-1, Netafim Streamline and D3 - 1.7 L h-1, NaanDanJain TalDrip); and the sub-subplots contained the evaluation times (0, 40, 80, 120 and 160 h). Distribution uniformity and statistical uniformity coefficients were evaluated every 40 h, until completing 160 h. The pH of the dilutions was the attribute posing the highest risk of clogging to the emitters. Also in relation to dilutions, P40 caused greater application non-uniformity in D2, while the highest values of application uniformity were achieved in treatments P10 and P20 with D1 and D3, indicating the effectiveness of dilution in minimizing clogging.
A presença do capital social nas comunidades atendidas pelos projetos de combate à pobreza rural (PCPR) em Pernambuco

Published: June 2020

Resumo Os programas de desenvolvimento têm contemplado cada vez mais a participação das comunidades na sua gestão. As idéias de participação tão conhecidas e defendidas pelas ciências sociais começaram a fazer sentido, mesmo que, pelo viés utilitarista, com o aparecimento do que se entende hoje por capital social. o capital social seria uma riqueza oriunda das relações sociais, possibilitando certos objetivos que sem ele não seriam alcançados. Os projetos de combate à pobreza rural (PCPR) em Pernambuco partem da crença de que mecanismos que incluem maior participação da sociedade civil e maior descentralização nas decisões sobre alocação de recursos financeiros tendem a gerar melhores resultados para comunidades rurais pobres. O capital social seria o fator que potenc1al1zana este modelo de desenvolvimento empregado no PCPR. A metodologia de trabalho do PCPR se dá através de financiamentos de projetos, onde a elaboração, implantação e operação são acompanhadas pelas comunidades, representadas pelas associações. O que se busca· entender, neste trabalho, é em que medida o capital social presente nas comunidades influencia a qualidade das organizações políticas que as representa.
O conceito de sociedade civil: em busca de uma repolitização
Authors: Alves Mário Aquino
Published: June 2020

Resumo Nos anos 90, os estudos sobre desenvolvimento, muitas vezes promovidos pelas agências internacionais de financiamento, passaram a atribuir uma ênfase muito grande nas ONGs e no seu papel crucial na construção da democracia e do desenvolvimento, tanto nos países pós-comunistas do Leste Europeu quanto nos países e desenvolvimento. Esta ênfase fez com que o termo "Sociedade Civil" passasse ao uso corrente em diversas esferas de conhecimento e, mais recentemente, também nos estudos organizacionais. Não raro, o conceito de "Sociedade Civil" está atrelado ao de "Terceiro Setor", funcionando mesmo como seu sucedâneo. A confusão entre os dois conceitos retrata uma forma de representação despolitizada da "parte pelo todo". O presente ensaio tem o propósito de resgatar o conceito de Sociedade Civil a partir de suas origens e principais linhas conceituais, procurando constituir um quadro referencial multidimensional para fixar um sentido mais "politizado" ao termo.
Reflexões sobre a autogestão a partir da experiência da cidade das cidades

Published: June 2020

Resumo Temos como objetivos, ao redigir esse texto: registrar um pouco da história e da experiência de um dos aspectos mais interessantes e menos abordados do Fórum Social Mundial - o Acampamento da Juventude; aportar alguma contribuição teórica para a reflexão sobre o que foi realizado e, principalmente, levantar questões para o futuro. A forma do texto é a de uma bricolagem de narrativas, percepções e reflexões. Um pouco revisamos a teoria, um pouco fazemos registros, um pouco analisamos, muito deixamos questões sem resposta... A idéia é que essas partes, ainda que não exatamente articuladas entre si, portem sentidos e despertem conversas. O artigo apresenta, sempre de forma breve, uma mistura d conceitos e revisões de abordagens sobre o tema da autogestão; a história do Acampamento Intercontinental da Juventude em cada um dos três Fóruns, destacando a proposta e a organização da gestão da Cidade das Cidades; segue-se, então, um item com reflexões críticas e perguntas em aberto provocadas pela narrativa, tendo como perspectiva a continuidade do processo de experimentação em torno do desenvolvimento de práticas de gestão (das organizações e do espaço) compatíveis com a possibilidade de um outro mundo.
Management techniques and organizational silencing: a manager’s account
Authors: Moura-Paula Marcos Júnior de , Moreira Patricia Aparecida Abreu , Ferraz Deise Luiza da Silva
Published: June 2020

Abstract this study analyzes the changes in the relations established in the work environment conditioned by the implementation of management techniques characterizing a Toyotist model and that produced the phenomenon of organizational silence. The story of a financial system worker was used as a guide for structuring our argument. Observations and documents mediated the understanding of the individual story along with the general social relations. Guided by the categories singularity, particularity and universality, we established the links among the worker’s situation, the company’s management techniques and the productive restructuring movement. The results show that the various management techniques were means of silencing built up throughout the worker’s career, as frustrations accumulated and the needs of the work process changed. What in the life of a manager is frustration and silence, in the totalization movement are changes in the being manager marked by the emptying of planning and controlling functions.

Abstract: The objective of this work was to evaluate the potential damage of the green-belly stink bug, Dichelops melacanthus, to corn in greenhouse and field conditions. Three trials were carried out. In the greenhouse, corn plants in the V1 stage were evaluated after each of them was infested with one insect in four developmental stages (nymphs of the third, fourth, and fifth instars and adults) during 14 days. In the field, corn plants in four developmental stages (V1, V3, V5, and V7) were infested inside cages with five adult stink bugs, also during 14 days. In another trial in the greenhouse, the same treatments of the field trial were conducted during 14 days, but with an infestation intensity of one bug per plant per pot. The control treatment was without infestation. In all trials, damage scores were attributed to the corn plants and the dry matter of the aerial part of the plants was determined. In the field, stem diameter and grain yield were also evaluated. Third-instar nymphs do not cause significant changes in the dry weight of the aerial part of the plant and in the damage scores, compared with the control treatment. Infestations by adult stink bugs cause more damage to corn plants in the V1 and V3 stages, both in field and greenhouse conditions.
Chain Length and CSPs Learnable with Few Queries

Published: June 2020

The goal of constraint acquisition is to learn exactly a constraint network given access to an oracle that answers truthfully certain types of queries. In this paper we focus on partial membership queries and initiate a systematic investigation of the learning complexity of constraint languages. First, we use the notion of chain length to show that a wide class of languages can be learned with as few as O(n log(n)) queries. Then, we combine this result with generic lower bounds to derive a dichotomy in the learning complexity of binary languages. Finally, we identify a class of ternary languages that eludes our framework and hints at new research directions.
Guiding CDCL SAT Search via Random Exploration amid Conflict Depression
Authors: Chowdhury Md Solimul , Müller Martin , You Jia
Published: June 2020

The efficiency of Conflict Driven Clause Learning (CDCL) SAT solving depends crucially on finding conflicts at a fast rate. State-of-the-art CDCL branching heuristics such as VSIDS, CHB and LRB conform to this goal. We take a closer look at the way in which conflicts are generated over the course of a CDCL SAT search. Our study of the VSIDS branching heuristic shows that conflicts are typically generated in short bursts, followed by what we call a conflict depression phase in which the search fails to generate any conflicts in a span of decisions. The lack of conflict indicates that the variables that are currently ranked highest by the branching heuristic fail to generate conflicts. Based on this analysis, we propose an exploration strategy, called expSAT, which randomly samples variable selection sequences in order to learn an updated heuristic from the generated conflicts. The goal is to escape from conflict depressions expeditiously. The branching heuristic deployed in expSAT combines these updates with the standard VSIDS activity scores. An extensive empirical evaluation with four state-of-the-art CDCL SAT solvers demonstrates good-to-strong performance gains with the expSAT approach.
