Understanding the Concept of Agentic Engagement
Authors: Montenegro Aida
Published: June 2017

Bearing in mind that agentic engagement has a recent history in comparison to the other types of engagement (behavioural, emotional and cognitive), this paper will present a theoretical review of this concept, including the reasons it has been denominated as the fourth type of student engagement. Agentic engagement is understood as the observable classroom event in which the learner constructively contributes to his/her learning and the instruction he/she receives (Reeve, 2012). The revision of research and theory on agentic engagement included in this paper supports the idea that it provides a consistent researchable field. Future research contributions may focus on (1) the disaffected face of agentic engagement, its conceptualization and its effects (Reeve & Tseng, 2011; Reeve, 2013) and (2) the understanding (description, typology and analysis) of students’ self-initiated contributions (proactive actions) in the classroom (Waring, 2011) in order to identify which strategies may facilitate students’ learning processes, teacher’s agentic engagement interventions, and student-teacher interaction.
Discovering Students’ Preference for Classroom Activities and Teachers’ Frequency of Activity Use
Authors: Samperio Sanchez Nahum
Published: June 2017

Choosing what activities to include in a class is not an easy task. Teachers often tend to include activities based on their teaching styles and sometimes students are not included in these decisions. This paper explores the preference students have for classroom activities and the frequency in which teachers include certain classroom activities in their practicum. The study followed a quantitative research methodology by collecting numerical data through a 62-items questionnaire developed from a pool of items gathered from different questionnaires. Analysis indicate a coefficient of reliability of α=.907; data were analyzed with the SPSS software. 20 English language teachers and their 263 students of a language school were included in the study. Students’ levels ranged from 1 to 6, being the 6th the equivalent to B1 of the Common European Framework (CFE). Results indicated a mismatch between teachers’ frequently used activities and students’ preference of activities, however, there is a match in speaking activities.

Published: June 2017

Los laboratorios de experimentación para los cursos de formación superior en sistemas de control pueden llegar a ser costosos, ya sea en su adquisición, operación o mantenimiento. Un recurso alternativo para disponer plataformas de experimentación son los laboratorios remotos; sin embargo, no siempre es posible obtener sistemas complejos. Una solución a este problema son los laboratorios de emulación remotos. En este artículo se describe el desarrollo de una aplicación web para la emulación de sistemas dinámicos utilizando una herramienta software de prototipado rápido de control de libre distribución basada en Linux/RTAI. La aplicación está enfocada especialmente a la experimentación con sistemas dinámicos que no están disponibles fácilmente en un laboratorio, donde el modelo es configurado por el usuario. Se presenta el diseño de la interfaz de usuario y el motor de procesamiento de los datos enviados. Se verificaron en el servidor de aplicación los tiempos de latencia del sistema operativo en tiempo real y la capacidad del sistema para reproducir señales similares a las de un sistema real a partir de un modelo emulado. El modelo de un evaporador fue utilizado como ejemplo para probar la funcionalidad de la aplicación. Una de las ventajas de la aplicación es la metodología de trabajo, que está basada en el desarrollo de bloques en Scicos, esto permite al usuario reutilizar esos parámetros y el código que implementó para construir un bloque sobre el Toolbox Scicos en el entorno Linux/RTAI/ScicosLab; además, se requiere solamente un navegador web y la máquina virtual de Java.

Individual Test Rig for Measuring the Creep Behaviour of Corrugated Board for Packaging
Authors: Köstner V. , Ressel JB. , Sadlowsky B. , Böröcz P.
Published: June 2017

Corrugated board is one of the most important and most popular packaging materials worldwide for transporting goods. Due to its hygroscopic behavior, it has a tendency to creep when subjected to stress under a constant load, which can ultimately result in loss of strength, with possible damage to products. The creep behavior of corrugated board is still a largely under-researched area. This paper attempts to examine the long-term behavior of corrugated board during use more precisely than before, and presents the first step and results of the research process. For the measurement, a compact and high-precision individual test rig was developed and used, in order to reduce the side effect of coupled systems, that is, to avoid their mutual influence. This paper successfully presents results reproducible with the described test rig apparatus for determining the creep behavior of corrugated board. It will be continued to publish further results of the research in the near future.
La competencia socioemocional docente en el logro del aprendizaje de las competencias genéricas del perfil de egreso de educación media superior / Teacher’s socio-emotional competency in achieving generic skills of the graduate profile in higher secondary
Authors: Garrido Natarén Patricia , Gaeta González Martha Leticia
Published: June 2017

Los cambios en la estructura familiar, las dinámicas y crecientes exigencias sociales, las nuevas competencias exigidas a los docentes y los pobres resultados alcanzados en la Educación Media Superior del Sistema Educativo Mexicano (INEE, 2012), hace de la enseñanza un proceso complejo que incrementa las tensiones emocionales del profesor (Marchesi, 2008). De ahí que en este trabajo se busca indagar sobre el nivel de desarrollo de la competencia socioemocional docente que contribuya al logro del aprendizaje de las competencias genéricas del perfil de egreso de Educación Media Superior en México. Se utilizó una metodología mixta; en la fase cuantitativa se usaron dos instrumentos estandarizados: el Test de Inteligencia Emocional Mayer-Salovey-Caruso (MSCEIT) y el Maslach Burnout Inventory (MBI), los cuales se aplicaron a 172 profesores de educación media superior. En la fase cualitativa se entrevistó a cinco docentes con los niveles más altos y cinco con los más bajos de competencia socioemocional (según los resultados del MSCEIT).En el presente texto se dan a conocer los hallazgos de la indagación cuantitativa. Los resultados del estudio mostraron que, en general, los docentes poseen una habilidad suficiente que les permite un desenvolvimiento con cierto grado de éxito, es decir, capacidad de percibir emociones; de acceder, generar y utilizar las emociones para ayudar al pensamiento, y regular las emociones para que promuevan el crecimiento emocional e intelectual. Asimismo, se encontraron parámetros no indicativos de diagnóstico de Síndrome de Burnout según el MBI.
Modulation of Complex-Spike Duration and Probability during Cerebellar Motor Learning in Visually Guided Smooth-Pursuit Eye Movements of Monkeys
Authors: Yang Yan , Lisberger Stephen G.
Published: June 2017

Activation of an inferior olivary neuron powerfully excites Purkinje cells via its climbing fiber input and triggers a characteristic high-frequency burst, known as the complex spike (CS). The theory of cerebellar learning postulates that the CS induces long-lasting depression of the strength of synapses from active parallel fibers onto Purkinje cells, and that synaptic depression leads to changes in behavior. Prior reports showed that a CS on one learning trial is linked to a properly timed depression of simple spikes on the subsequent trial, as well as a learned change in pursuit eye movement. Further, the duration of a CS is a graded instruction for single-trial plasticity and behavioral learning. We now show across multiple learning paradigms that both the probability and duration of CS responses are correlated with the magnitudes of neural and behavioral learning in awake behaving monkeys. When the direction of the instruction for learning repeatedly was in the same direction or alternated directions, the duration and probability of CS responses decreased over a learning block along with the magnitude of trial-over-trial neural learning. When the direction of the instruction was randomized, CS duration, CS probability, and neural and behavioral learning remained stable across time. In contrast to depression, potentiation of simple-spike firing rate for ON-direction learning instructions follows a longer time course and plays a larger role as depression wanes. Computational analysis provides a model that accounts fully for the detailed statistics of a complex set of data.
Context Mediated
Authors: Pickford Benjamin
Published: June 2017

Benjamin Pickford, “Context Mediated: Ralph Waldo Emerson’s Political Economy of Plagiarism” (pp. 35–63)

Context has long been a critical determiner of methodologies for literary studies, granting scholars the tools to make objective claims about a text’s political or economic relation to the situation of its genesis. This essay argues that Ralph Waldo Emerson anticipatively criticizes our commitment to such practices through his use of plagiarism—a literary mode that exemplifies the denial of the sovereignty of context. I focus on two core principles that underlie Emerson’s conception of literature’s civic role in Essays: Second Series (1844): first, that literature is driven by an impulse to decontextualize; second, that this means that it has a deep affinity with the deterritorializing logic of capital. Provocatively proposing Emerson as a theorist of the relation between literature and economics, I argue that Essays: Second Series shows how the literary text can negotiate its ineluctable culpability with capitalism, but this does not mean that it can presume to possess a privileged point of vantage that might deny such culpability. Given that this is precisely what much historicizing or contextualizing scholarship implies, I contend that Emerson gives us a case study in the limits of literature and criticism’s economic agency.

В статті здійснено аналіз кредитування аграрних підприємств банківськими установами України. Аргументовано, що найбільшим фінансовим донором для суб’єктів господарювання аграрного сфери виступає банківський сектор. Доведено, що сутність державного регулювання у вирішенні питань кредитування аграрного бізнесу полягає у створенні сприятливої політики кредитування через часткову компенсацію ставки за кредитами банківських структур.  Умотивовано, що зменшення рівня кредитування сільськогосподарських товаровиробників в період фінансової кризи обумовлено низкою чинників. Обгрунтовано, що ефективне господарювання не можливе без поповнення обсягів фінансових ресурсів для збільшення оборотного капіталу та інвестування діяльності суб’єктів господарювання, а, звідси,  збільшення їх прибутковості. Аргументовано, що поповнення коштів можливе через залучення інвестицій з метою поповнення оборотних активів, що, у свою чергу, дасть можливість поповнити, оновити основні засоби виробництва та збільшити прибутковість господарюючих суб’єктів  і для вирішення даних питань потрібна нагальна участь державних регуляторів.
Dissecting the Satellite DNA Landscape in Three CactophilicDrosophilaSequenced Genomes
Authors: de Lima Leonardo G , Svartman Marta , Kuhn Gustavo C S
Published: June 2017

Eukaryote genomes are replete with repetitive DNAs. This class includes tandemly repeated satellite DNAs (satDNA) which are among the most abundant, fast evolving (yet poorly studied) genomic components. Here, we used high-throughput sequencing data from three cactophilic Drosophila species, D. buzzatii, D. seriema, and D. mojavensis, to access and study their whole satDNA landscape. In total, the RepeatExplorer software identified five satDNAs, three previously described (pBuM, DBC-150 and CDSTR198) and two novel ones (CDSTR138 and CDSTR130). Only pBuM is shared among all three species. The satDNA repeat length falls within only two classes, between 130 and 200 bp or between 340 and 390 bp. FISH on metaphase and polytene chromosomes revealed the presence of satDNA arrays in at least one of the following genomic compartments: centromeric, telomeric, subtelomeric, or dispersed along euchromatin. The chromosomal distribution ranges from a single chromosome to almost all chromosomes of the complement. Fiber-FISH and sequence analysis of contigs revealed interspersion between pBuM and CDSTR130 in the microchromosomes of D. mojavensis. Phylogenetic analyses showed that the pBuM satDNA underwent concerted evolution at both interspecific and intraspecific levels. Based on RNA-seq data, we found transcription activity for pBuM (in D. mojavensis) and CDSTR198 (in D. buzzatii) in all five analyzed developmental stages, most notably in pupae and adult males. Our data revealed that cactophilic Drosophila present the lowest amount of satDNAs (1.9–2.9%) within the Drosophila genus reported so far. We discuss how our findings on the satDNA location, abundance, organization, and transcription activity may be related to functional aspects.

Activity and isozyme content of aspartate transaminase in cow reproductive organs at different physiological states and ovarian hypofunction were studied. It was registered, that activity of aspartate transaminase (AST) in ovarian tissue and endometrium at corpus luteum state is 132.0 ± 8.23 and 172.9 ± 8.70 μm/min×mg of protein, lower on 26.3 and 5.5% at follicle growth and at early corpus luteum is 66.5 ± 2.10 and 147.1 ± 13.26 μm/min×mg of protein. Lowest AST activity is registered at hypofunction state (61.8 ± 4.57 і 146.1 ± 9.33 μm/min×mg of protein). In cow reproductive organ tissues and antral fluid from ovarian follicles was registered two bands of proteins, that have AST activity. In reproductive organs main part is mitochondrial isozyme (АSТ2; 78.8–97.7%) in antral fluid – cytosole (АSТ1; 72.8–88.2%). In ovarian and uterus tissues was established high enzyme activity at late corpus luteum, that characterizes intensive aspartate conversion to oxaloacetate and possible utilization of substeates to maintain energetic and sytnthetic needs in cow reproductive organs. Antral fluid of big follicles from ovarian at follicle growth and at state of late corpus luteum characterizes by high activity and content of AST, that points on follicle cell growth – granulose and oocyte. In ovarian tissue and endometrium at hypofunction lower activity and isozyme content point on substrate deficiency for transamination and violation of physiological functions.

The changes of calcium, phosphorus, magnesium foals for hypercalcitoninemia was studied. In the first months of life calcium metabolism were altered. During the first month of life the majority of foals (85.7 percent) is hypocalcemia. Obviously, it is physiological, because in this period of life calcitonin promotes in osteocytes inhibition of enzymes that break down bone tissue to ensure the consolidation of the skeleton. In later life foals for hypercalcitoninemia hypocalcemia was observed less in one - and two-month old she was found in 57.1% of the foals; in three - to five-month old – at 42.9%. In the six-month old foals, values of total calcium in blood serum were within the physiological range (2.15–of 2.63 mmol/l). Relatively ionized calcium, its content in foals for hypercalcitoninemia was practically the same during the whole period of studies (0.96 ± 0.019 mmol/l in first day of life – 1.0 ± 0.014 mmol/l at six months of age). The proportion of the ionized form of macroelements to total calcium was stable and ranged from 48.8 per cent after the birth to 47.0% in 5 months old. Only six-month foals she was the lowest and amounted to 43.0% of the content of total calcium in serum. The other macroelements – phosphorus and magnesium in foals with hypercalcitoninemia were not significantly different from animals with physiological quantities of the hormone. In particular, the content of phosphorus, regardless of age, almost all animals were within the range of 0.9 to 1.18 mmol/l (only in some animal figures were less – 0.81–0.76 mmol/l). The content of magnesium in the blood serum of foals with hypercalcitoninemia was in the range of 0.91 – of 1.16 mmol/l.

The dependence of the criteria of the reproductive ability of cows on the duration of lactation was studied. The duration of the lactation period (300–450 days) for highly productive cows is optimal for: the service period, the insemination index, the interval interval and the exit of the calves. On average, on farms, the average duration of the service period did not differ significantly between them and did not depend on the system of cows' content and amounted to 302 ± 60.9 and 307 ± 61.3 days, respectively. A similar tendency can be naturally traced in the parameters of the inter-interval interval. The increase in lactation time of cows negatively affects the indicators of their reproductive capacity and economic data. The total costs for one animal from additional changes and shortages of calves were the highest in the third research groups and amounted to 1458 and 1946 UAH. according. It is established that the duration of the lactation period affects the reproductive performance of cows

The study shows works of numerous authors considerable variability organ localization of tumors in different animal species. 135 cases of neoplasms of different localization were analyzed. Among the animals that had tumors, there were dogs, cats, rats, guinea pigs, gerbils, hamsters, hares, rabbits and reptiles. The largest proportion were dogs and cats. The average age of dogs with neoplasms ranged about 8 years, cats – about 9. The number of dogs with neoplasms up to a year was less than that of cats. The level of detection of tumors in dogs remained equally high throughout life, and in cats gradually grew to 10 years and was a maximum of 13 years. It is shown that irrespective of the type of small animals kept by the inhabitants of Kiev, the greatest percentage of tumors falls on the skin and the mammary gland. In dogs, skin tumors are placed in the first place, while in cats and rodents, neoplasms of the mammary gland are on the first place. Frequent in dogs were neoplasms of testes, whereas in cats this pathology was not recorded. In dogs and rodents ovarian tumors had a significant percentage. Ovarian tumors in cats giving place colon tumors. In dogs and cats almost at the same level recorded tumors localized in the mouth. In addition to these noted a tumor of the uterus, spleen, kidneys, lungs, eyes and more. But the frequency of detection was less than 3% of cases. Features of organ localization of tumors is important for understanding the tumors nature.

The aim of the study was to explore the impact of the preparation «Fos-Bevit» on cholesterol content and the concentration of uric acid in the organism of cows and the course of their postnatal period. The experiment conducted in LLC «Agroprodservice-Invest» of Kozivskyi district, Ternopil region on cows of Ukrainian black and white dairy cattle breed. In order to design the scheme of the preparation usage with immunostimulating properties we used «Fos-Bevit» – a complex preparation of production of LLC SPC «Brovafarma» based on butafosfan and three group B vitamins (nicotinamide, folic acid, cyanocobalamin), which apply to cattle metabolic disorders, vitamin deficiency, as a stimulant and a tonic preparation to boost the body's resistance to diseases of various etiologies, improving the growth and development. Having used the preparation «Fos-Bevit» intramuscular in dose of 0,3 ml/10 kg of body mass for 1.5 day after calving in the blood of cows increases the cholesterol content by 10.69% (P ≤ 0.05) and decreases by 14.27% (P ≤ 0.05) the concentration of uric acid, which contributes to the activation of the body's antioxidant system and metabolism. The preparation «Fos-Bevit» positively influence the after born period that can be observed the decrease of service period by 75 days (Р ≤ 0,01) and decrease of the index of insemination for 0.4 item in comparison with cows of the control group in which subclinical endometritis and mastitis were diagnosed. The preparation «Fos-Bevit» is recommended for including into the technological scheme of prophylaxis of afterbirth diseases in cows.

Authors: Hernández Liz C. , Bahamón Nelson
Published: June 2017

Se presenta el procedimiento matemático para estimar la incertidumbre en la calibración de tacómetros ópticos. Por tratarse de un dispositivo de baja jerarquía en mediciones de tiempo y frecuencia, se utiliza el concepto estadístico de desviación estándar para considerar la componente de incertidumbre por repetibilidad en lugar de la estabilidad.Se considera una situación relevante y frecuente en tacómetros consistente en que la componente por resolución es dominante; esto tiene una importante implicación al momento de escoger el factor de cobertura para la obtención de la incertidumbre expandida ya que no se tienen las condiciones para satisfacer de forma aproximada el teorema del límite central.

Published: June 2017

En este trabajo se propone e investiga un modelo matemático de redes delincuenciales. Este problema se formula en el marco de la teoría de juegos, uno de cuyos conceptos principales es el de equilibrio de Nash. Se discute cómo el problema de encontrar un equilibrio de Nash da lugar a un problema de satisfacción de restricciones y cómo éste se puede analizar usando métodos de la mecánica estadística, cuya formalización matemática es un tema de investigación muy activo en la actualidad. Desde el punto de vista computacional, tales métodos dan lugar a algoritmos de paso de mensajes que permiten obtener propiedades estadísticas de interés, tales como el nivel de actividad delincuencial promedio y el número de equilibrios de Nash.
Evasão e abandono escolar na educação básica no Brasil: fatores, causas e possíveis consequências
Authors: Silva Filho Raimundo Barbosa , Araújo Ronaldo Marcos De Lima
Published: June 2017

Neste artigo, objetivou-se trazer para o debate algumas considerações sobre evasão e abandono escolar na educação brasileira. Verifica-se a necessidade de ter como eixo a compreensão de suas dimensionalidades, pois suas formas de interpretação não permitem chegar a uma definição precisa. Os próprios órgãos oficiais da educação trazem à tona a falta de conceito claro. Fatores internos e externos contribuem diretamente para que a evasão e o abandono se perpetuem. O Brasil tem a terceira maior taxa de abandono escolar entre os 100 países com maior IDH. A evasão é um processo muito complexo, dinâmico e cumulativo de saída do estudante e pode ser vista como expulsão escolar. As metas estipuladas pela Constituição Federal de 1988, que determinam a universalização do ensino fundamental e a “erradicação” do analfabetismo, ainda não se concretizaram. A “evasão” pode ser considerada um “ato solitário” e pode denotar o próprio fracasso das relações sociais; não tem uma origem definida e por isso não terá um fim por si só. Drogas, sucessivas reprovações, prostituição, falta de incentivo da família e da escola são alguns dos fatores que podem levar o educando a sair da escola. Observa-se que existem três dimensões conceituais indispensáveis à investigação da evasão escolar.

O PIBID/CAPES constitui-se em um espaço privilegiado para a formação dos estudantes de licenciatura, proporcionando uma inter-relação entre teoria e prática necessárias para o cotidiano profissional docente. As discussões que sustentam este trabalho tratam das contribuições do programa para a formação inicial de professores na área de Pedagogia. Utilizou-se uma abordagem quanti/qualitativa, do tipo estudo de caso, aplicando questionários que foram respondidos por 23 dos 30 bolsistas de Iniciação à Docência (ID) do subprojeto Pedagogia, de uma Instituição de Educação Superior comunitária e filantrópica do Rio Grande do Sul. O instrumento fez parte da autoavaliação institucional com o objetivo de analisar os impactos dos projetos desenvolvidos na formação dos estudantes na instituição. Foram avaliadas sete questões de múltipla escolha relativas ao desenvolvimento profissional docente dos bolsistas ID; segundo as respostas dos acadêmicos, os fatores de contribuição do PIBID agruparam-se nas seguintes categorias: relação teoria-prática, estímulo à produção de conhecimento a partir da prática, interesse em formação permanente e necessidade de inter-relação entre as áreas de conhecimento. Além disso, todos esses aspectos foram percebidos de forma consciente pelos estudantes, o que deixou evidente que o PIBID também contribui para a maturidade deles no exercício da futura profissão.

The influence of game genre on Internet gaming disorder
Authors: Na Euihyeon , Choi Inyoung , Lee Taek-Ho , Lee Hyeseon , Rho Mi Jung , Cho Hyun , Jung Dong Jin , Kim Dai-Jin
Published: June 2017

Background and aims

Although Internet gaming disorder (IGD) has been investigated in detail, minimal research has been conducted regarding the influence of different game genres on IGD. The aim of this study is to compare the characteristics of members of game genre-specific groups with IGD and to identify factors associated with IGD status in each group in a large sample of adults.

Methods

Internet games were categorized into four genres: real-time strategy games, massive multiplayer online role-playing games (MMORPG), sport games, and first-person shooter (FPS) games. Participants (n = 2,923) who usually played one of these games completed an anonymous online survey that collected sociodemographic, game usage pattern, and psychopathological assessment data.

Results

MMORPG and FPS game players more frequently met the criteria for IGD than participants in the other two groups. Differences between the IGD-suspected gamers within the genre-specific groups were observed for a few items, such as average game-playing time and the subscales of the behavioral activation system; however, the factors that contributed to the development of IGD within each game genre-specific group were found to be considerably different.

Discussion and conclusions

The findings of this study suggest that IGD is a stable psychiatric diagnosis encompassing users of a broad range of game genres. In addition, the development of strategies for the prevention of and early intervention on individuals at high risk for developing IGD may require consideration of the distinct characteristics identified as effective predictors of IGD in users of each game genre.

Usługi publiczne w polityce zrównoważonego rozwoju gmin − wybrane problemy
Authors: Słupik Sylwia
Published: June 2017

The aim of this study is to identify the main barriers municipalities face and the benefits they gain from implementing sustainable development from authorities point of view. The paper also presents the main directions and activities public authorities have implemented in technical and environmental public services. It also discusses the results of empirical research conducted in 2015 in municipalities in the voivodeships of Wielkopolska, Silesia and Podlasie. The main conclusion of the research is that effectively implementing sustainable development policy largely depends on the awareness and involvement of local authorities. The paper shows that in many municipalities, economic, social and environmental development factors aren’t balanced. Moreover, sustainable development programming and activity should improve the quality of life for inhabitants, but they often fail to leave the planning stage.
Otoczenie fiskalne jako czynnik rozwoju biznesu i konkurencyjności gospodarki
Authors: Sosnowski Michał
Published: June 2017

The article examines the impact of the fiscal environment on business development and increasing competitive advantage, both in individual companies and the economy as a whole. This issue is particularly challenging in the context of Poland’s membership in the European Union and the globalisation of economic processes. For this purpose, I have analysed and evaluated tax policy used by OECD countries, particularly the level of taxation, tax burden, tax wedge and the shadow economy. In my research I have sought to find a relationship between these values and the development of entrepreneurship and an economy’s competitiveness. The conclusion is that excessive tax burdens have a negative impact on activity by registered enterprises, may decrease the economy’s competitiveness and stimulate harmful activities from a social and economic point of view. In contrast, the experience of many OECD countries shows that reducing fiscal burden is a worthwhile measure to take.
Rolnictwo ekologiczne i perspektywy jego rozwoju w Polsce w świetle doświadczeń unijnych
Authors: Golik Danuta , Żmija Dariusz
Published: June 2017

The aim of the paper is to analyse the potential and development of organic farming in selected countries of the European Union, so as to assess the prospects for its development in Poland. Organic farming is currently one of the fastest growing agricultural sectors in the European Union. In Poland, the market for organic products is at an early stage of development. Barriers to development are associated with both the area of supply and the demand for organic products, which is increasing but still limited. With demand occurring mostly in large cities, organic products have limited availability and are expensive.
