Do funding applications where peer reviewers disagree have higher citations? A cross-sectional study
Authors: Barnett Adrian G , Glisson Scott R. , Gallo Stephen
Published: July 2018

Background: Decisions about which applications to fund are generally based on the mean scores of a panel of peer reviewers. As well as the mean, a large disagreement between peer reviewers may also be worth considering, as it may indicate a high-risk application with a high return.

Methods: We examined the peer reviewers' scores for 227 funded applications submitted to the American Institute of Biological Sciences between 1999 and 2006. We examined the mean score and two measures of reviewer disagreement: the standard deviation and range. The outcome variable was the relative citation ratio, which is the number of citations from all publications associated with the application, standardised by field and publication year.

Results: There was a clear increase in relative citations for applications with a higher mean. There was no association between relative citations and either of the two measures of disagreement.

Conclusions: We found no evidence that reviewer disagreement was able to identify applications with a higher than average return. However, this is the first study to empirically examine this association, and it would be useful to examine whether reviewer disagreement is associated with research impact in other funding schemes and in larger sample sizes.
Fortress with Sticky Moats: the Functional Role of Small Particles around Tetragonisca angustula Latreille (Apidae: Hymenoptera) Nest Entrance
Authors: Alves Amaro , Sendoya Sebastian F. , Rech André Rodrigo
Published: July 2018

Many bee species are able to defend themselves against pollen or honey thievery. We herein report the functional role of small sticky particles deposited by Tetragonisca angustula Latreille in its nest entrance external side. This strategy was very effective to prevent ants from invading the bees’ nest. We reported many dead ants attached to the nest entrance and different ant species easily immobilized after being moved onto the entrance tube containing sticky particles. This is the first description of the functional role played by the nest entrance sticky particles under natural conditions..
Seed removal by ants in Brazilian savanna: optimizing fieldwork
Authors: Angotti Marina Acero , Rabello Ananza , Santiago Graziele , Ribas Carla
Published: July 2018

There has been an increase in the number of studies using seed removal by ants to evaluate ecosystem functioning; however, these studies encompassed varying time periods and used different types of seeds. Therefore, our aim was to evaluate differences in the proportion of seeds removed by ants in impacted and non-impacted sites in Brazilian savanna. Furthermore, we evaluated seed removal (1) during the morning and after a 24h period of seed exposure and (2) using natural and artificial seeds (manipulated resource to resemble natural seeds). The proportion of seeds removed was higher after the 24h exposure period (artificial seeds) regardless of site status, and more artificial seeds were removed than natural seeds. Our recommendations regarding sampling period depend on whether evaluating impacted or non-impacted sites. Although seed removal was greater after 24h in both impacted and non-impacted sites, we suggest that research evaluating the proportion of seeds removed in non-impacted sites should be performed only in the morning period to optimize the sampling time (removal of 60% during this period). When the aim is to compare non-impacted and impacted sites, we suggest evaluating after 24h of exposure, since the impacted sites experienced a higher proportion of seed removal during the afternoon and/or night time periods. Furthermore, we recommend the use of artificial seeds because they are easier to obtain and manipulate, and allow us to do comparisons between studies at different regions. We consider these findings an important first step towards standardizing future research on seed removal in Brazilian savannas by facilitating fieldwork and allowing comparisons to be made among different studies.
The Influence of Extrafloral Nectaries on Arboreal Ant Species Richness in Tree Communities
Authors: Madureira Marcelo Silva , Sobrinho Tathiana Guerra , Schoereder José Henrique
Published: July 2018

Studies investigating the role of resource availability in the species richness patterns can elucidate ecological processes and contribute to conservation strategies. In this study, we test two hypotheses: i) arboreal ant species richness increases with abundance of extrafloral nectaries-bearing trees; and ii) arboreal ant species richness increases with the diversity of extrafloral nectaries-bearing trees. We used data of ant sampling and tree inventories from 30 plots of Brazilian Cerrado. Arboreal ant species richness was positively influenced by the proportional abundance of extrafloral nectaries-bearing trees, total tree density and total tree diversity. There was no effect of species richness of extrafloral nectaries-bearing trees. Coefficient of determination of proportional abundance of extrafloral nectaries-bearing trees was larger when compared to coefficient obtained using tree density as explanatory variable. These results suggest that variation in arboreal ant species richness is better explained by extrafloral nectaries-bearing tree abundance than total tree density. Generalist foraging behavior of sampled ant species may explain their association with proportional abundance of extrafloral nectariesbearing trees and their non-significant relation with proportional richness of extrafloral nectaries-bearing tree species. Extrafloral nectaries-bearing trees abundance may be a specific estimate of the amount of food resource available in plots. Thus, this is a more specific way to quantify which resources may explain variation of the arboreal ant species richness in tree communities. We hope these results will be helpful to understanding the local variation in ant species richness and as criteria to biodiversity conservation.

Published: July 2018

In order to understand the effects of human impacts on structure and functioning of tropical forests, we should consider studies on animal-plant interactions such as antplant mutualistic interactions.We investigated the mutualistic interactions between ants (Azteca genera) and Cecropia plants in habitats of secondary forest and pasture used as cattle fields. We tested for the following hyphothesis: (i) Cecropia from pasture are more susceptible to foliar herbivory than the Cecropia from the forest, and (ii) the defense promoted by ants of Azteca genus is less efficient in the pasture when compared to the forested areas. We selected four areas inserted in Atlantic rain forest domain surrounded by secondary forest and by cattle pastures. The herbivory was more intense in the pasture than in the secondary forest. The presence of Azteca species diminished foliar herbivory only in the forested areas, where we observed a significant increase in herbivory after the removal of A. alfari colony. We argue that the greater herbivory in pasture occurs probably due the lack of other plant resource, being Cecropia paschystachya Trécul and C. glaziovii Snethl., isolated in a “sea of grass” without connection with other tree vegetation, opposite scenario observed in forested habitats. The defense of Azteca only in the secondary forest, leading us to suppose that: 1) not even the your aggressive behavior is able to reduce the intense herbivory in the pasture; 2) the your behavioral pattern in forest is not the same in deforested environments and / or 3) mutualism may be undergoing changes due to abiotic effects on pasture.
Review of Ants (Hymenoptera: Formicidae) as bioindicators in the Brazilian Savanna
Authors: Tibcherani Mariáh , Nacagava Vivian Ayumi Fujizawa , Aranda Rodrigo , Mello Ramon Luciano
Published: July 2018

The Brazilian Savanna is threatened mainly by the expansion of agriculture and livestock. Regarding environmental problems, habitat loss in the biome and the need to verify studies on ants as bioindicators, the goal of this paper was to carry out a bibliographic review of the literature about ants as bioindicators in this biome from the last 30 years. We searched papers about ants as bioindicators in the Brazilian Savanna from the last 30 years, refining the search between the years 1986 to 2016 and we analyzed 16 papers about ants as bioindicators. Monitoring studies focusing on ants as bioindicators in the Brazilian Savanna started in 1992 and increased since 2002. The results obtained in the studies presented changes in the species richness and composition in relation to potential bioindication. In general, 167 species are defined as bioindicators of the Brazilian Savanna and are related to specific habitats. We verified that most studies were done Minas Gerais state. We noted that the absence of rigorous analysis damaged the results of the studies, as well as the knowledge of ant fauna biology for correct attribution of indication characteristics of preserved or degraded areas.
Discovery of the termite specialist ant genus Centromyrmex, Mayr 1866 (Hymenoptera: Formicidae: Ponerinae) for the Guiana Shield
Authors: Franco Weslly , Feitosa Rodrigo Machado
Published: July 2018

The ponerine ant genus Centromyrmex is recorded for the first time in French Guiana. The specimens reported here were collected by the SEAG (Société Entomologique Antilles-Guyane) team in the commune of Saül, French Guiana. The ants were collected in a region of Amazon Forest with flight interception traps. Two out of the three species currently recognized for the genus in South America were here recorded in French Guiana, Centromyrmex alfaroi and Centromyrmex gigas. In total, 24 specimens were collected, all represented by alate queens. This record expands the knowledge about the distribution of this rarely collected genus and reinforces the importance of alternative sampling techniques for collecting cryptobiotic ants and unknown alate forms.

Published: July 2018

Since the middle of the 20th century, human activities have led to overall ecosystem contamination and to major modifications in landscape structure and composition. Mining activities represent a major source of environmental contamination by metal residues. The objective of our study was to evaluate the presence of heavy metals and other elements on stingless bee pollen, and compare them to samples of Suspended Particulate Material (SPM) in five points a Mineral Province, in Brazil. More than 50 elements were identified by ICP-OES and ICP-MS, after microwave digestion. Overall, we found a strong relation among elements present on pollen and SPM. Samples from the four areas exhibited higher levels of minerals compared to the reference site. Mineral levels varied widely within the two seasonal periods. Some elements, like Pb, Cd, As, Cu, Zn, and Fe were found at levels considered potentially toxic to human health. Pollen stored by stingless bees was a successful bioindicator, and demonstrated the value of quantitative ecological information for detecting air pollution.
Characterization of Epidermal Lipoxygenase Expression in Normal Human Skin and Tissue-Engineered Skin Substitutes
Authors: Simard-Bisson Carolyne , Parent Lorraine Andrée , Moulin Véronique J. , Fruteau de Laclos Bernard
Published: July 2018

Lipoxygenases (LOXs) are enzymes likely to be involved in corneocyte lipid envelope formation and skin barrier function. In humans, mutations in epidermis-type lipoxygenase 3 ( eLOX-3) and 12R–lipoxygenase ( 12R-LOX) genes are associated with autosomal recessive congenital ichthyosis (ARCI), whereas deletion of these genes in mice causes epidermal defects. LOXs also represent a matter of interest in psoriasis as well as in cancer research. However, their expression as well as the exact role of these enzymes in normal human skin have not been fully described. Our goal was to characterize the expression of epidermal LOXs in both normal human skin and Tissue-Engineered Skin Substitutes (TESS) and to consider TESS as a potential model for LOX functional studies. Staining for epidermal differentiation markers and LOXs was performed, in parallel, on normal human skin and TESS. Our results showed similar expression profiles in TESS when compared with native skin for e-LOX3, 12R-LOX, 12S-lipoxygenase (12S-LOX), and 15-lipoxygenase 2 (15-LOX-2) but not for 15-lipoxygenase 1 (15-LOX-1). Because of their appropriate epidermal differentiation and LOX expression, TESS represent an alternative model for future studies on LOX function.
La sistematización de la ducha. Del instrumento de cura al dispositivo de higiene
Authors: De Gispert Hernández Jordi
Published: July 2018

La sistematización de la ducha popular desde finales del siglo XIX, es producto de la voluntad de eficacia militar. Este proceso parte de la centralización radial de sus instalaciones y tiende a fragmentar y seriar programáticamente su espacio y tiempo. La ducha se promueve y obliga en los establecimientos públicos, instruyendo a los niños, a los locos y a los delincuentes en la práctica de la ducha periódica como una obligación necesaria, para posteriormente resurgir como un deseo.La guerra iguala a todo el mundo como combatiente en una causa de Estado. La ducha, que inicialmente parecía exponerse como un arma de guerra, pasa a ser una máquina de Estado y presenta, para el individuo nómada, la movilidad de la ducha colectiva, concluyendo con su individualización. La ducha se introduce en el camino de su comercialización masiva, presentándose la paradoja de la individualización como síntesis de la sistematización y de la eficacia en fase de itinerancia.

Adaptar a educação a uma sociedade em mudança: Redes de circulação do escolanovismo e a difusão do pragmatismo em África nos anos 20 e 30
Authors: Madeira Ana Isabel
Published: July 2018

Educational Adaptations in a Changing Society is the final report arising from two conferences that took place, in July 1934, in Johannesburg and Cape Town, under the auspices the New Education Fellowship. These conferences addressed three fundamental questions related to the role of education in leading social change: the aim of the educational effort, the methods involved, and the content of what should be taught and when. These general concerns sought to respond to the rapid social and economic changes taking place in South Africa (and in other European colonies) at that period: urbanization, school massification, racial conflict, etc. By urging educationalists, philosophers, teachers, administrators and churchmen alike to co-operatively discuss educational reforms and pedagogical technologies adapted to the African context (vocational training, adapted curricula, rural education, moral instruction, etc.) the conference sought to create a reformist environment were the ideals of progressive educational thought intertwined neatly with the social gospel of the protestant movement. It is in this context that I propose to address Dewey’s participation in the conference, not as an individual outstanding pragmatist voice, but as a conceptual persona, who makes it possible to understand theories, ideas and visions of educational modernization as discursive constructs envisaged for the colonial terrain. I will try to tackle the question of policy transfer not as an active borrowing strategy from one context to another, but as an indigenization of concepts and ideas that are passed on by threads of broader colonial discourses and modes of colonial governance.
The Experience of Being a Lay Teacher in Catholic Schools: An Approach for Investigating the History of an Under-researched Field
Authors: O'Donoghue Tom
Published: July 2018

Internationally, there has been a major output of empirical research on Catholic education over the last two decades. However, it has not been accompanied by a similar corpus of related work indicating possible new directions such research could take, including those that could be undertaken by using a diverse range of methodologies on a wide range of topics neglected to date. This paper indicates one such direction that could be taken in relation to historical research on lay teachers in Catholic schools from the 1940s to the present. First, the historiographical work that has been undertaken on the history of teachers more broadly is considered. An overview on the official status of the laity and the lay teacher historically within the Church is then considered. Finally, an argument for the use of a «life story» research approach for the generation of research questions to investigate the experience of being a lay teacher in Catholic schools. The approach is suitable for «insider research», where the focus is on investigating issues that were of concern for participants, rather than on pursuing pre-ordained questions of interest to the researcher and which usually arise primarily from a reading of the relevant background literature only.
West Meets East. A Well-Rounded Education versus an Angular Education in Japan
Authors: Obara Kazuhito
Published: July 2018

The idea of a well-rounded education is widely recognized, and as IB programs and the concept of an IB education are gradually yet steadily infiltrating the Japanese education system, Japan can no longer ignore the existence of a Zenjin («whole person») education, which was first practiced in 1921 by a Japanese philosopher of education named Kuniyoshi Obara. This paper compares the philosophical and theoretical foundations of Obara’s Zenjin education and a so-called «well-rounded» education, revealing the similarities between them and using these as a rationale for educational reform in Japan. In the literature review, the recent debate between well-rounded and angular education proponents is addressed, and it is concluded that a well-rounded education still has a role to play, even though there are a certain number of competitive and prestigious universities/colleges that question its merits and give priority to high school graduates who have specialized solely in one area, such as sports, arts, or a standard-deviation-value-oriented, angular education. Regardless of the fact that attaining good scores on academic tests is often thought to be a reasonable way for children to meet their aspirations and expectations and receive benefits from a meritocracy and an academic hierarchy, especially in Japan, this paper insists that a true form of education should be concerned with each individual’s whole personality, and therefore a Zenjin, or well-rounded, education must play a core role in the education system. Indeed, the current Japanese education system is collapsing and deteriorating, exposing children to serious problems such as bullying, school-related suicides, etc. so preventative measures urgently need to be put in place, and it is time to think carefully about what a Zenjin education has to teach us.
History of the Reception of Montessori Education in Japan
Authors: Yonezu Mika
Published: July 2018

This paper focuses on the history of the reception of Montessori Education, and sheds light on the development of childhood education in Japan. From its first adoption in the 1910s until today, the Montessori style of Education has been both praised and criticised. Nevertheless, this period has seen three distinct phases of theory and practice. The first stage (1910s-1930s) saw, from its initial adoption, a rapid acceptance of Montessori Education, due to its promise of early education and new teaching methods promoting freedom for children. However, the method soon lost popularity because some educators criticized the weakness of Montessori’s theory. In the second stage (1930s-post-World War II), interest in the method continued to grow, albeit gradually, and several books published on the Montessori Method in Europe and America were translated into Japanese. The third stage (1950s-present) saw the so-called «Montessori revival», in which the method caught on again with many educators. Many original works were translated, numerous studies on Montessori appeared, and the number of kindergartens and nursery schools using the Montessori Method increased. Much has been said both for and against Montessori’s concept of «freedom for children». Recently, however «learning from the environment» has become an important topic in early childhood education in Japan. Montessori attaches importance to children’s freedom to interact with each other and their environment, leading to a renewed interest in the Montessori method and the theory behind it. This paper seeks to clarify the transitions in the popularity of Montessori Education and analyse its value to Japan.
Formulation of a Carbonated Herbal Health Drink with Hemidesmus indicus root extract
Authors: Singh Ritesh Ranjan
Published: July 2018

The study was done to formulate a drink from an old medicinal herb and retain all the potential benefits with a new taste and flavor. For this an herbal drink was formulated and its quality ascertained. In the first part of the study, syrup was prepared from the raw roots of the herb with addition of acids and flavors. Then this syrup was diluted (in the ratio of 20:80, i.e., 20% syrup and 80% water) further followed by carbonation with the rate of 6.2 g of CO2 per liter of the diluted drink and bottled. Three samples were prepared namely, Control samples T0(Control sample, without essence), T1(Kewada essence) and T2 (Rose essence). In the next part, prepared samples were subjected to sensory evaluation and chemical analysis when fresh and after regular intervals at room temperature (27±1 °C) and refrigerated temperature (below 70C). Microbial analysis of the product was done to check the quality of the herbal drink and self-life of the product. The control sample T0 was the most acceptable due to its unique taste and flavor, followed by samples T1 and T2. The present study entailed to conclude that preparation of a drink with hemidesmus indicus roots extracts gives a new taste and flavor with high nutritional values. This drink can be stored safe for nearly a month if carbonated and storage at refrigerated temperature (below 50C).
Research on IP fast Recovery based on Multi-topology Routing
Authors: Liu Xinyuan , Wang Hui , Zhang Limin
Published: July 2018

In order to reduce the need for rerouting of IP fast rerouting (rerouting the number of hops added by the packet). Based on the basic principle of multi-route backup configuration, this paper proposes a new backup topology generation method based on the ordering of important nodes in complex networks. The main idea is to sort the nodes in the network topology by using the K-Shell decomposition algorithm and introduce the contribution between the nodes, and then select the key nodes for the generation of the backup topology. The experimental results show that the proposed algorithm can effectively reduce the number of rerouting hops and verify the feasibility and effectiveness of the algorithm.

This paper proposes a nonlinear control methodology for three phase grid connected of PV generator. It consists of a PV arrays; a voltage source inverter, a grid filter and an electric grid. The controller objectives are threefold: i)
ensuring the Maximum power point tracking (MPPT) in the side of PV panels, ii) guaranteeing a power factor unit in
the side of the grid, iii) ensuring the global asymptotic stability of the closed loop system. Based on the nonlinear
model of the whole system, the controller is carried out using a Lyapunov approach. It is formally shown, using a
theoretical stability analysis and simulation results that the proposed controller meets all the objectives.
Seismic Analysis of Multi-Storied Building with Shear Walls using ETABS
Authors: Jaswanth B. , Surendra Y. L. , Kumar M. Ravi
Published: July 2018

Shear walls are structural members used to elongate the strength of R.C.C. structures. These shear walls will be
construct in each level of the structure, to form an effective box structure. Equal length shear walls are placed
symmetrically on opposite sides of outer walls of the building. Shear walls are added to the building interior to
provide more strength and stiffness to the building when the exterior walls cannot provide sufficient strength and
stiffness. It is necessary to provide these shear walls when the tolerable span- width ratio for the floor or roof
diaphragm is exceeded. The present work deals with a study on the improvement location of shear walls in
symmetrical high rise building. Position of shear walls in symmetrical buildings has due considerations. In
symmetrical buildings, the center of gravity and center of rigidity coincide, so that the shear walls are placed
symmetrically over the outer edges or inner edges (like box shape). So, it is very necessary to find the efficient and
ideal location of shear walls in symmetrical buildings to minimize the torsion effect. In this work a high rise building
with different places of shear walls is considered for analysis. The multi storey building with 8 story’s is analyzed for
its displacement, strength and stability using ETABS-2015 software. For the analysis of the building for seismic
loading with Zone-III is considered with soil III. The analysis of the building is done by using equivalent static method
and dynamic method.

Authors: Thakur Ashish , Leake Okqubamariam , Mariam Micheal G.
Published: July 2018

The main purpose of this research was to investigate crack propagation resistance of shaft. Hollow transmission
composite shafts were produced and their crack behavior was investigated. Glass fiber-reinforced polyester polymer
composite material is used for the hollow transmission shaft of Hidasie H260 helicopter model of Dejen Aviation
Engineering Complex, DAEC. The elastic engineering constants of composite transmission shaft are determined using
the Classic Laminate Theory, CLT. Linear Elastic Fracture Mechanics, LEFM was used to analyze its crack
propagation by taking a through-thickness central crack. The stress at the crack tip is analyzed and it was found that
the glass fiber-reinforced polyester polymer composite transmission shaft has good resistance to crack propagation.
FEA method was used to crack propagation analyses. The model of shaft is generated using Finite Element Method.
Due to the symmetry of the problem, only a quarter part of it is modeled and analyzed. The crack-tip region was
meshed using quarter point (singular) 8-node quadrilateral elements to get accurate results and the analysis used a
fit of the nodal displacements in the vicinity of the crack tip. The maximum stress is at the crack tip since there is a
stress concentration at sharp edges.
Challenges in Circumferential Entry Blades for Structural Integrity of Closing Blade in Steam Turbines
Authors: SureshBabu A. S. , G Jeevan Gowda , Reddy M. V.
Published: July 2018

The bladed disc of an LP last stage rotor assembly in a steam turbine often employs circumferential entry blades. The closing blade is fastened with the aid of a pin type locking mechanism, which locks the closing blade onto the disc. Radial entry blade root design demands for a groove in the disc through which blades are inserted and guided to their respective final positions which alters the stiffness in the disc. Closing blade is the most highly stressed weak link zone in the circumferential entry rotor disc achieving mechanical integrity for in-service condition is a challenge. Location of pin and its insertion is the key to achieve the desired in-service life with good material model. The present research work focus on emphasis of pin positioning to lock the T-root blade at operating range. Various material model configurations and pin positions are considered in both blade and disc to improve the reliability in design. Customized methodology is developed to address the elasto-plastic kinematic hardening in pin, disc and blade grove during in-service life. Finite element approach along with classical design equations followed by API 616 standards is employed to achieve the mechanical integrity in bladed disc assembly.

Published: July 2018

This paper presents the concepts of three evolutionary algorithms i.e, ant colony optimization and particle swarm
optimization algorithm. An evolutionary algorithm copies the way how evolution occurs in the nature. There are
various types of evolutionary algorithms. This paper focuses on ACO and PSO algorithms. ACO provides solution to
various optimization problems. It follows the principle of survival of the fittest. Various problems such as knapsack
problem, TSP(travelling salesman problem) can be solved using genetic algorithm. Ant colony optimization is a
heuristic algorithm which follows the behaviour of ants i.e., the way ants seek food in their environment by starting
from their nest. Particle swarm optimization algorithm (PSO) is also an optimization algorithm which also uses a
method of searching using some heuristics.
Micronuclei Formation Is Prevented by Aurora B-Mediated Exclusion of HP1a from Late-Segregating Chromatin inDrosophila

While it is known that micronuclei pose a serious risk to genomic integrity by undergoing chromothripsis, mechanisms preventing micronucleus formation remain poorly understood. Here, we investigate how late-segregating acentric chromosomes that would otherwise form micronuclei instead reintegrate into daughter nuclei by passing through Aurora B kinase-dependent channels in the nuclear envelope of Drosophila melanogaster neuroblasts. We find that localized concentrations of Aurora B preferentially phosphorylate H3(S10) on acentrics and their associated DNA tethers. This phosphorylation event prevents HP1a from associating with heterochromatin and results in localized inhibition of nuclear envelope reassembly on endonuclease- and X-irradiation-induced acentrics, promoting channel formation. Finally, we find that HP1a also specifies initiation sites of nuclear envelope reassembly on undamaged chromatin. Taken together, these results demonstrate that Aurora B-mediated regulation of HP1a-chromatin interaction plays a key role in maintaining genome integrity by locally preventing nuclear envelope assembly and facilitating the incorporation of late-segregating acentrics into daughter nuclei.
Parents’ Adverse Childhood Experiences and Their Children’s Behavioral Health Problems
Authors: Schickedanz Adam , Halfon Neal , Sastry Narayan , Chung Paul J.
Published: July 2018

BACKGROUND AND OBJECTIVES:

Adverse childhood experiences (ACEs) include stressful and potentially traumatic events associated with higher risk of long-term behavioral problems and chronic illnesses. Whether parents’ ACE counts (an index of standard ACEs) confer intergenerational risk to their children’s behavioral health is unknown. In this study, we estimate the risk of child behavioral problems as a function of parent ACE counts.

METHODS:

We obtained retrospective information on 9 ACEs self-reported by parents and parent reports of their children’s (1) behavioral problems (using the Behavior Problems Index [BPI]), (2) attention-deficit/hyperactivity disorder diagnosis, and (3) emotional disturbance diagnosis from the 2013 Panel Study of Income Dynamics (PSID) core interview and the linked PSID Childhood Retrospective Circumstances Study and 2014 PSID Child Development Supplement. Multivariate linear and logistic regression models were used to estimate child behavioral health outcomes by parent retrospective ACE count.

RESULTS:

Children of parents with a history of 4 or more ACEs had on average a 2.3-point (95% confidence interval [CI]: 1.3–3.2) higher score on the BPI, 2.1 times (95% CI: 1.1–3.8) higher odds of hyperactivity, and 4.2 times (95% CI: 1.7–10.8) higher odds of an emotional disturbance diagnosis than children of parents with no ACEs. Maternal ACEs revealed a stronger association with child behavior problems than paternal ACEs. Relationships between parents’ 9 component ACEs individually and children’s BPI scores revealed consistently positive associations. Mediation by parent emotional distress and aggravation were observed.

CONCLUSIONS:

Parents with greater exposure to ACEs are more likely to have children with behavioral health problems.

Published: July 2018

В статті розглядаються процеси розвитку земельних відносин та становлення ринку землі вконтексті формування продовольчої політики України. Обґрунтовується необхідність капіталізації рин-ку землі для забезпечення сталого розвитку нашої країни. Зазначається, що основною умовою збіль-шення внеску земельного капіталу в економічне зростання є застосування економічних методів регу-лювання землекористуванням, спрямованих на гарантування стабільності і добробуту суспільства приодночасному збереженні екологічного потенціалу. Тому в форматі сучасних трансформаційних зру-шень важливу роль відіграє визначення вартості землі, яка б відповідала наявним умовам господарю-вання та сприяла доходності національної економіки. Ефективна аграрна, а отже і продовольча полі-тика щодо земель сільськогосподарського призначення повинна бути обумовлена завданнями із за-безпечення власної продовольчої безпеки, створенням домінантних позицій на світових ринках про-довольства.

The problems of formation of revenues of local budgets are investigated in the article. It has been established that significant centralization has affected the reduction of financial independence of local selfgovernment bodies. Changes in the management of local budgets caused by the introduction of a decentralized model encourage local self-government bodies to attract additional financial resources and form a certain economic potential. The feasibility of introducing a public-private partnership through the application ofdifferent methods and tools based on the form of interaction of project participants is substantiated. Suchcooperation requires the organization of complex, mixed private-public structures that can provide largescale infrastructure projects with resources. The advantages of project financing of economic development ofterritories in the framework of public-private partnership (PPP) are revealed.In order to ensure the financial attractiveness of projects implemented on the basis of public privatepartnership and aimed at ensuring the sustainable economic development of regions, it is recommended touse organizational models such as DBFO (Design, Build, Finance, Operate) and DBO (Design, Build, Operate).
