Ammonium Uptake Is the Main Driver of Rhizosphere pH in Southern Highbush Blueberry
Authors: Imler Christopher S. , Arzola Camila I. , Nunez Gerardo H.
Published: May 2019

Unlike most horticultural crops, blueberry (Vaccinium spp. section cyanococcus) prefers low-pH (4.2–5.5) soils. Other plants can acidify their rhizosphere to create a hospitable microenvironment. Southern highbush blueberry (SHB; Vaccinium corymbosum interspecific hybrids) plants do not acidify their rhizosphere in response to Fe deficiency, but other factors that affect rhizosphere pH have not been elucidated. We report results from two hydroponic experiments exploring N uptake effects on the rhizosphere pH of ‘Emerald’ SHB. Ammonium (NH4+) uptake led to rhizosphere acidification, whereas nitrate (NO3–) uptake led to rhizosphere alkalization. When grown in a split-root hydroponic system, roots that took up NH4+ acidified the rhizosphere to a greater extent that roots not exposed to NH4+. Rhizosphere acidification was observed even in a nontreated control. These results suggest that NH4+ uptake is the main driver of rhizosphere pH in SHB. N form effects suggest that fertilization with NO3– might lead to undesirable rhizosphere alkalization.
Drought Tolerance of Navajo and Lovell Peach Trees: Precision Water Stress Using Automated Weighing Lysimeters

Published: May 2019

Native American tribes have been cultivating peaches [Prunus persica (L.) Batsch] since their introduction to North America in the 1600s. In the American Southwest, peach orchards derived from centuries of seed selections have been maintained in relative isolation from commercial cultivars. These Native American peach selections may be better adapted to the arid climate of the Intermountain West. We compared physiological robustness during water stress of seedling peaches from a 60-year-old orchard maintained by Navajo farmers in southwestern Utah to the commercial peach rootstock Lovell. Six replicate trees of each rootstock were subjected to eight cycles of controlled drought on an automated lysimeter system, which monitored transpiration rate continuously. Trees were selected for uniform size and transpiration rate at the start of the study. During the drought cycles, individual trees were watered when their transpiration rate decreased to less than 250 g of water per day, ≈20% of their well-watered daily transpiration rate. After the first cycle of drought, the transpiration rate of the Navajo trees was greater than the Lovell trees, so they depleted their root-zone water more rapidly and experienced greater water stress. Despite greater stress, the Navajo selection had greater leaf area and dry weight at harvest. Because the root system was confined, these results indicate that the Navajo selection may have greater resilience when experiencing drought, independent of the depth and distribution of the root system. However, this study was not able to determine whether physiological resilience during drought was a result of canopy or root characteristics. Field studies are needed to determine whether root distribution or depth also contribute to drought tolerance in the Navajo selection.
Morphophysiological Effects of Chromium in Sour Orange (Citrus aurantium L.)
Authors: Shiyab Safwan
Published: May 2019

This is the first study on the performance of sour orange (Citrus aurantium L.) in soil contaminated with chromium (Cr). A greenhouse experiment was conducted to determine the phytotoxic effect of Cr on seed germination and seedling growth of sour orange. Cr treatments were applied as Cr(NO3)3 in five concentrations (0, 50, 100, 150, and 200 ppm). A gradual increase in Cr concentration leads to inhibition of seed germination and other growth parameters. Phytotoxicity, relative water content (RWC), seed vigor index (SVI), and the tolerance index (TI) show a significant decrease up to 100 ppm as a result of the presence of metal. Biochemical constituents, nutrient uptake, antioxidative enzymes, and lipid peroxidation under Cr stress were also investigated. The results indicate that concentrations greater than 100 ppm Cr cause an increase in plant antioxidative enzymes—superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX)—and increased lipid peroxidation. On the other hand, sour orange effectively generated an enzymatic antioxidant defense system (especially CAT) to scavenge hydrogen peroxide (H2O2), resulting in less H2O2 in shoots with greater Cr concentrations. A majority of Cr accumulated in the shoots and low translocations to shoots. However, sour orange is the best universal rootstock for citrus because of its resistance to salinity and disease. It also grows well in heavy soils. Based on the results of this study, sour orange might be a potential candidate plant for phytofiltration of contaminated water and phytostabilization of Cr-contaminated soils.
Analysis of Flower Color Variations at Different Developmental Stages in Two Honeysuckle (Lonicera Japonica Thunb.) Cultivars
Authors: Li Jianjun , Lian Xiaoya , Ye Chenglin , Wang Lan
Published: May 2019

Lonicera japonica Thunb., known as Japanese honeysuckle or golden-and-silver honeysuckle, belongs to the honeysuckle family and is native to eastern Asia, including China, Japan, and Korea. Microscopy, spectrophotometry, colorimetry, and the Royal Horticulture Society of Colorimetric Card (RHSCC) were used to compare and analyze the pigment distribution, content, and color variations in the Yujin 2 and Damaohua cultivars at different developmental stages. There were notable differences in the corolla color and the cross-section color between different developmental stages and different varieties. The lightness (L*), redness (a*), and yellowness (b*) values were calculated for each period for the two cultivars to observe variation trends. The chlorophyll content in the corollas of both cultivars showed declining trends with different rates. The chlorophyll content decreased rapidly from the young period to the two white period, and changed gradually from the two white period to the golden period. Moreover, the carotenoid content declined slightly from the young period to the silver period and rose sharply during the golden period. The ratio of these two pigment contents increased dramatically during the golden period: by 11.51 and 6.53 times in ‘Yujin 2’ and ‘Damaohua’, respectively. There were significant differences in corolla color, cross-section color, and the content of three pigments between the two varieties of honeysuckle. distribution and variation of pigments were the key factors affecting the flower color of honeysuckle. This study provides a basis for the identification and breeding of honeysuckle varieties and lays a foundation for further studies on the function and molecular mechanisms of pigments.
UV-blocking High-tunnel Plastics Reduce Japanese Beetle (Popillia japonica) in Red Raspberry
Authors: Cramer Maria E. , Demchak Kathleen , Marini Richard , Leskey Tracy
Published: May 2019

Insecticides are the primary tool raspberry growers use to control Japanese beetles (Popillia japonica), but reliance on pesticides is costly and there are risks to nontarget species. Based on observations that Japanese beetles were less abundant on raspberries in high tunnels than in fields, we investigated the effects of plastic films that transmit different amounts of ultraviolet (UV) light to Japanese beetles. Many insects are sensitive to light in the UV-A range and use it for navigation. High-tunnel plastics that block varying percentages of UV radiation are increasingly available. We grew two primocane-fruiting red raspberry cultivars, Polka and Josephine, in tunnels with six different covering treatments. Five were plastics that blocked the UV range to varying degrees, and one was a no-plastic treatment. In 2016, beetles were counted and removed from the plants by hand daily. In 2017, beetles were removed by hand every 4 to 5 days. Foliage temperature was measured in each tunnel twice in 2017 with an infrared (IR) thermometer. Spectral transmittance characteristics of the plastics were measured with a spectroradiometer in 2015 and 2018. Mean beetle counts by date and for the whole season were compared for the plastics and cultivars. Japanese beetle numbers were significantly greater in the no-cover treatment than in all plastic treatments. The plastic that blocked more than 90% of the UV-A range usually had significantly lower beetle populations than the plastics that blocked the least UV-A. Overall, it appears that using a UV-blocking plastic can reduce Japanese beetle aggregation and feeding damage on raspberries, decreasing the need for other control. This could benefit growers by reducing the cost of insecticides and decreasing exposure risk for nontarget organisms.
Identification and Characterization of a Loquat Aneuploid with Novel Leaf Phenotypes

Published: May 2019

A loquat (Eriobotrya japonica) seedling obtained from an open-pollinated triploid variety ‘Wuheguoyu’ (2n = 3x = 51) was verified as aneuploid and designated H39. It was shown to have five extra chromosome copies (2n = 39) compared with the diploid plant (2n = 2x = 34), one additional copy each for the 2nd, 4th, 7th, 9th, and 11th chromosomes. A number of novel features of leaf morphology was observed for H39 in comparison with ‘Ruantiaobaisha’ (2x, female progenitor) and ‘Wuheguoyu’ (3x, female parent), including increased leaf width, reduced leaf thickness, and narrowed palisade mesophyll and wax coat. Total chlorophyll content in unit area of H39 leaves was close to or slightly less than the diploid and triploid parent lines. Chlorophyll content in unit mass showed the opposite trend, with H39 having higher amount than the 2x and 3x. As we expected, H39 had the lowest net photosynthetic rates among the three lines. Furthermore, 8-month-old scions of H39 grew more slowly than those of the diploid and triploid lines, especially in plant height, which was much reduced (P < 0.01). These results indicated that the aneuploid H39 was a potential germplasm for breeding dwarfing loquat rootstock or interstock.
Puccinia sambuci Infection of American Elderberry Plants
Authors: Warmund Michele R. , Mihail Jeanne D. , Hensel Kaley
Published: May 2019

Elderberry rust (Puccinia sambuci Schwein.) Arthur (=P. bolleyana) (Arthur, 1921) disease is frequently found in commercial American elderberry (Sambucus nigra L. subsp. canadensis L.) plantings when an alternate host, Carex sp., is present. To evaluate potential infection periods of P. sambuci on elderberry plants, micrometeorological conditions were monitored. Rust symptoms were observed on elderberry on 5 Apr. 2016, and conditions favorable for possible infection were 9 to 18 °C, ≥3 hours of continuous leaf wetness, and ≥85% relative humidity. Studies were also conducted to ascertain whether P. sambuci with varying pustule numbers affects fruiting, berry puree quality, or vegetative growth. Fruit yield was reduced by 31% when potted ‘Bob Gordon’ elderberry averaged six rust pustules per plant compared with noninfected plants. In another experiment, field-grown ‘Wyldewood’ plants averaging 137 rust pustules/cane at harvest had 47% less fruit weight on canes than uninfected canes. Titratable acidity of fruit puree from plants was lower when plants had either 690 rust pustules/plant or 137/pustules/cane, but soluble solids and pH of puree were unaffected by P. sambuci infection. The effect of rust infection on vegetative growth of elderberry plants also varied with pustule numbers. With a low infection level (six pustules per plant), P. sambuci did not induce premature leaf loss on ‘Bob Gordon’ plants or adversely affect shoot dry weight at the end of the growing season. When P. sambuci infection on ‘Wyldewood’ plants was more severe (137 pustules/cane), greater leaf loss occurred on infected canes than on uninfected canes. At very high infection levels (690 pustules/plant), ‘Bob Gordon’ plant dry weight was reduced. Because of the potential for fruit yield loss on elderberry plants, control of P. sambuci at relatively low infection levels on this plant may be warranted. Strategies that eliminate or suppress the alternate host would likely reduce the P. sambuci inoculum and limit the potential for elderberry plant infection.
Effect of Tomato Rootstock on Hybrid and Heirloom Tomato Performance in a Midwest High Tunnel Production System
Authors: Lang Kristine M. , Nair Ajay
Published: May 2019

High tunnels allow vegetable growers to extend the growing season, increase crop production, and improve produce quality. Tomatoes (Solanum lycopersicum L.) are the most widely grown crops in high tunnels; however, tomato production in high tunnels can be challenging. Continuous cropping in high tunnels can increase soil-borne disease pressure and can lead to soil salinity or nutrient depletion issues. Based on preliminary research, we hypothesized that use of the rootstock ‘RST-04-106-T’ would increase yield and quality of heirloom and hybrid tomato scions compared with nongrafted plants. To test this hypothesis, our research objectives were to assess marketable yields, fruit quality and nutritional value, and plant growth of grafted and nongrafted hybrid and heirloom tomatoes in a high tunnel production system. Grafted and nongrafted ‘Cherokee Purple’ (heirloom) and ‘Mountain Fresh Plus’ (hybrid) tomatoes were grown in the same high tunnel for two seasons (7 May–20 Oct. 2015 and 29 April–7 Oct. 2016) at the Horticulture Research Station in Ames, IA. Grafted plants produced significantly more marketable fruit, although marketable and total fruit weight did not increase significantly. Individual fruit size was unaffected by grafting. Across cultivars, mean soluble solids content (SSC) in fruit was 0.3 °Brix lower in grafted plants as compared with the nongrafted control. Grafting did not affect lycopene content of fruit. Grafting increased stem diameter by an average of 0.8 mm, but overall plant biomass was unaffected. The effect of grafting on leaf chlorophyll concentration (SPAD readings) was mixed. In addition, grafting increased leaf chlorophyll concentration in ‘Cherokee Purple’ but decreased it in ‘Mountain Fresh Plus’ plants. Grafting is a valuable tool in tomato production, but the impact of ‘RST-04-106-T’ rootstock use appears to be specific to certain soil types with high incidence of bacterial wilt.
Redde Rationem: Keynes, Minsky and the Collapse of Long-Term Capital Management Twenty Years Later
Authors: Radonjić Ognjen
Published: May 2019

The aim of this paper is to indicate, through study of the Long-Term Capital Management near-bankruptcy case, fallacies of modern financial theory. Model assumptions that determine the validity of theory must be realistic. The responsibility of academic community in the process of creating economic policy is significant since only valid theory could result in economic policies that would successfully deal with the instability of global world economy. On the other hand, if this fact remains ignored, it is reasonable to expect recurrent financial shocks in the future.
Music as a Tool for Informants’ Self-Representation at the Anthropological Field
Authors: Ćuković Jelena
Published: May 2019

It has been shown multiple times so far, in ethnological and anthropological literature, that music is very important for studying cultural identity, precisely because it is a significant part of it. In this exposition, based on parts of the interviews that I conducted on several different fields, I wish to deepen the general thesis that the role the music has in creating our identity is not only known to the researchers, but also to the informants, hence it could be deliberately used for representative purposes. This actually concerns three cultural (ethnic) groups: a group of Slovak women, a Serbian family that emigrated from Croatia, and a group of students from Jamaica who were at the students’ programme in South Carolina. What all of these groups’ informants had in common was the fact that instead of using oral answers, they were representing themselves (through belonging to the certain community) using the songs and their lyrics from the music contingent, which they considered to originate from their community, and these were expected to answer my questions more appropriately than their verbal answers. The aim of this paper is to examine whether this type of informants’ expression, if it has been used as a part of a representative strategy, can be interpreted through the analytical concept of identity politics, and if the anthropologists’ and ethnologists’ position can be problematized in the complex process of decoding the informants’ answers in the methodological sense, and as a passive participant in the interviewees’ strategy.
The Concept of Culture between Enlightenment and Counter-Enlightenment
Authors: Kulenović Nina
Published: May 2019

The paper seeks to show that criticisms directed at the expense of the concept of culture from the sixties, and especially the eighties of the twentieth century, only but re-actualized the dispute present in the discipline at least from the end of the second decade of the twentieth century between two sides. On the one hand, we have those anthropologists who perceived culture as (a) homogeneous, static, closed, holistic, sui generis system that, in the ontological sense, "exists" outside and above individuals, and determines their thinking and actions by anticipating them, and which "represents" in a monographic study, and in a methodological sense, explains the totality of life, beliefs and behavior of its members. On the other hand, there are anthropologists who perceived culture as (b) in the ontological sense "nonexistent", fragmentary, heterogeneous, variable set of actions of numerous individuals struggling to create, interpret or legitimize its rules, and whose disagreements, in a methodological sense, are taken as the starting point of the culture’s explanation, understood as an aggregate of numerous individuals’ work and their unintended consequences. The aim of the paper is to contextualize the Individualism-Holism Dispute into the Enlightenment and Counter-Enlightenment dispute, and answer the question why rationalists, agents of transcultural commensurability and advocates of universally applicable, cosmopolitan anthropological science, when writing "against culture," refer to the defense of Enlightenment from Counter-Enlightenment.

We have conducted a molecular genetic study of the pectinase PGU genes of 74 strains of the yeast Saccharomyces bayanus var. uvarum, isolated from various fermentation processes and natural sources in different regions of Europe and in the USA. Unlike S. cerevisiae, each having a PGU gene, strains of S. bayanus var. uvarum have three divergent genes PGU1b, PGU2b and PGU3b, located respectively on chromosomes X, I and XIV. The high pectinolytic activity of these yeasts appears to be related to the presence of several PGU polymeric genes in their genome.

The applicability of laser aerosol particle counters for the registration of microscopic fungal spores in the airborne state (including in the presence of background concentrations of atmospheric airborne particles) was demonstrated during the experiments, and a technique was developed to transfer large (from one to several tens of microns in diameter) fungal spores to the air-suspended state, and to register them confidently with a resolution ensuring their identification. Despite the relatively large size of spores, their detection by the aerosol particle counter is possible for a period of time sufficient to track the movement of spores over significant (compared to conventional dust particles) distances. At the same time, according to the results of measurements, it is possible to judge not only the presence of spores in the air, their size, quantity and ways of movement, but also to draw some preliminary conclusions about their properties, in particular, about the tendency to glue and form aggregates.

The Policies and Process of Preserving the Historical and Heritage Buildings in Dubai City: Case Study of Historical District
Authors: Alhasawi Mai
Published: May 2019

Preserving historical buildings is considered of one of the major priorities in many cities in both developed anddeveloping countries. Dubai is one of the major world cities that is experiencing rapid architectural transformations, thus the Dubai Municipality has taken the initiative to preserve historical buildings maintaining the culture and identity of the city’s heritage. This initiative started in 1991 under a unit called ‘The Unit for the Restoration of Historic Buildings’, which expanded further in 1994 to become ‘Architectural Heritage Department’. Over the years, the department has developed a mechanism of action, objectives, laws and strategies to keep abreast of progress and modernity in the field of repair, conservation and project management. In accordance with international and international standards while preserving the architectural character of the Emirate of Dubai.This paper is it a critical review to assert advantages and disadvantages of the policies and regulations that were set up by Dubai Municipality in terms of how they support the preservation of historical heritage and culture within the city. This paper is related my PhD research, Data was attained using existing documentations on policies, regulations, plans, books and available articles on historical buildings preservation. Findings show that the plan of work for preserving heritage and historical areas in Dubai is efficient and dynamic as it encompasses international standards and regulations while maintaining the cultural values of the city.The analysis shed light upon potentially creative perspectives in terms of protecting and preserving heritage buildings in similar environments. The paper provides a solid foundation for future research on heritage buildings, related complexities and the strategies employed by different governments to make informed decisions.
Votive Altars: Domestic Signals to Inhabit the Sacred
Authors: Sapio Valentina
Published: May 2019

«“Sacred” is an Indo-European word meaning ”separate”. The Sacred, therefore, [. . . is] a quality that is inherent in that which has relation and contact with powers that man, not being able to dominate, perceives as superior to himself, and as such attributable to a dimension [. . . ] thought however as ”separate” and ”other” with respect to the human world » Galimberti, (2000). The so-called votive altar, autonomous or attached to a major building often present in the Mediterranean countries, belong to the dimension of the Sacred.Votive altars - present in an old neighborhood of peasant origin in the suburbs of Naples called Ponticelli - are almost always placed in the interstices between street and courtyard (a self-built residential typology modeled over time by the inhabitants and which often forms the matrix of many neighborhoods popular Neapolitan). They keep and exhibit little sculptures and drawings of Jesus, Madonnas, and Saints of the Catholic religion, mixed with ancestors portraits and photos of relatives dead of the inhabitants, drawing on the ancient domestic cult of the Romans of Lari and Penati; it is certainly not a consciously cultured reference, but a mysterious ”feeling” that is common among primitive and popular cultures and that unravels through the centuries unscathed. Placed at the entrance of the living space, the altar expresses the sign of a difference, of a territorial change, separates ”ours” from ”yours”, welcomes, does not reject, but marks an open and inclusive threshold.With the paper, we want to study this phenomenon of ”primitive” culture and not regulated by laws, a mix of diffuse sacredness and popular magic, deepening the ”design” aspects of it, building an abacus in which to highlight potential and free references to the visual arts of these ”design works without designers”, and finding out new signs of the Sacred in the City in our time.

Clinical Management of Drug-resistant Mycobacterium tuberculosis Strains: Pathogen-targeted Versus Host-directed Treatment Approaches
Authors: Al-Ghafli Hawra , Al-Hajoj Sahal
Published: May 2019

Background:

Despite exerted efforts to control and treat Mycobacterium tuberculosis (MTB)
strains, Tuberculosis (TB) remains a public health menace. The emergence of complex drug-resistant profiles,
such as multi-drug resistant and extensively drug-resistant MTB strains, emphasizes the need for
early diagnosis of resistant cases, shorter treatment options, and effective medical interventions.

Objective:

Solutions for better clinical management of drug-resistant cases are either pathogencentered
(novel chemotherapy agents) or host-directed approaches (modulating host immune response
to prevent MTB invasion and pathogenesis).

Results:

Despite the overall potentiality of several chemotherapy agents, it is feared that their effectiveness
could be challenged by sequential pathogen adaptation tactics. On the contrary, host-directed
therapy options might offer a long-term conceivable solution.

Conclusion:

This review discusses the main suggestions proposed so far to resolve the clinical challenges
associated with drug resistance, in the context of TB. These suggestions include novel drug delivery approaches
that could optimize treatment outcome and increase patients’ compliance to the treatment.
What Role Does Distributed Leadership Play in Implementing Professional Learning Communities?
Authors: Goos Nick , Martin Barbara N.
Published: May 2019

This multiple case study examined three Midwestern elementary schools identified as having successfully implemented professional learning communities for many years. From the data, themes emerged indicating that there are key distributive components to successful leadership in implementation of the school improvement initiative. The findings in this study demonstrate that successful leaders create a collaborative culture, seek shared leadership and decision-making practices and have a narrow focus on student learning. Implications for principals and leadership preparatory programs are significant.
Medical Tourism and the Egress of Economic Depression: The Case of Assisted Reproduction Services in Greece
Authors: Laspa Christina
Published: May 2019

While the international literature has examined how the domestic population growth and domestic fertility rates affect economic growth, there is no research about how the foreign fertility rates can affect the domestic economic growth. The bridge on foreign fertility rates and domestic economic growth is the assisted reproductive health services provided through the market of medical tourism. Libertarian legal frameworks may attract health travelers for In Vitro Fertilization (IVF) and contribute to GDP growth from the side of the tourism industry. The present paper discusses this point of view as a vehicle for depressed economies such as Greece that enjoys a high expertise in IVF and tourism. A simplistic attempt of the potential turnover to the clinics is presented by estimating the future medically assisted births. The results give a clue of how a dynamic part of medical tourism can result beneficially for the exodus of economic depression.

QoS Analysis Of Kinematic Effects For Bluetooth HC-05 And NRF24L01 Communication Modules On WBAN System
Authors: Faiqurahman Mahar , Novitasari Diyan Anggraini , Sari Zamah
Published: May 2019

Wireless Body Area Network (WBAN) consists of a number of sensor nodes that are attached to the human body, and intended for monitor the human body condition. The WBAN system has several wireless communication modules that are used for sending or exchanging data between sensor nodes and gateway nodes or gateway nodes. There are some factors that are used to decide which communication modules should be implemented on WBAN system, including communication efficiency, distance range, power consumption, and the effect of mobility on QoS. In this study, we analyze the impact of the kinematic movement of sensor nodes on QoS parameter of HC-05 Bluetooth and NRF25L01 communication modules, during sending and receiving process among nodes. We assume that the sensor node and gateway node are attached on the limbs to catch the movement. We use Quality of Service (QoS) parameters such as delay, jitter, and packet loss, to analyze the impact of movement on communication modules. Based on the experimental result, it was found that the average value of delay and jitter for booth communication modules was slightly influenced by the speed of the sensor node movement. During the sensor node movement and data transmission, we found that the NRF24L01 module have a lower delay and jitter value than Bluetooth HC-05 module. The percentage of packet loss tends to be stable at 0% value, even though the speed value becomes higher.

La valoración económica de los recursos naturales ayuda a identificar opciones que permitancompatibilizar el desarrollo de una localidad y la conservación de sus ambientes naturales.Una de las metodologías que suele emplearse para estimar dicha valoración es la Disposicióna Pagar (DAP). El objetivo de nuestro trabajo fue evaluar la DAP por los serviciosecosistémicos que brindan dos áreas protegidas de la localidad de Puerto Deseado. Para ellose utilizó el método de valoración de contingente, que a través de la realización de encuestaspermite estimar la DAP de los individuos por la provisión o mejora de un bien ambiental.Para el armado de la encuesta se consideraron diferentes dimensiones: socioeconómicas; depreferencias de visita; estado de las áreas protegidas; problemas detectados; disponibilidad ymodo de pago para conservar el status ambiental de las áreas protegidas. Se encuestó un totalde 126 personas (74 residentes y 52 turistas). Para determinar cuál o cuáles variablesconsideradas pueden determinar la DAP se utilizaron análisis univariados y modelos deregresión logística. El modelo que mejor explicó la DAP incluyó como variables predictivas:lugar de residencia, si posee o no empleo y la percepción sobre el estado de las áreasprotegidas. Según las encuestas, y en comparación a la respuesta de los turistas, la comunidadde Puerto Deseado mostró una mayor disposición a invertir en mantener o mejorar el estadode conservación de ambas áreas. Personas con empleo y con mayor salario mostraron unamayor DAP positiva. Los que están dispuestos a pagar demandan mayor control, vigilancia einfraestructura en las áreas protegidas. La fauna y paisaje local son los principales motivos devisitas, lo que señala la importancia de políticas de gestión tendientes a conservar el entornolo más prístino posible. Se espera que los resultados obtenidos en este trabajo, sumados afuturos, sirvan para que el concepto de valoración de los servicios ecosistémicos pueda seraplicado en una gestión más equitativa y efectiva de las áreas protegidas y sus recursosnaturales.
Agregando valor al bosque fueguino. Una descripción de las Políticas públicas para la segunda transformación de la madera en Tierra Del Fuego. 2004 – 2017
Authors: Delgado Juan
Published: May 2019

El presente trabajo propone realizar una descripción de las políticas públicas para el sector foresto-industrial  de Tierra Del Fuego durante el período 2004 – 2017. Este sector cuenta con más de un siglo de antigüedad en la Provincia, basando su actividad principalmente en la madera de lenga (Nothofagus Pumilio) proveniente del Bosque Andino Patagónico  generando en la actualidad alrededor de unos 70 mil metros cúbicos de rollizos, de los cuales menos del 20% se destina a la transformación secundaria en la Provincia. Si bien el primer antecedente de participación del Estado en la organización de una exhibición es del año 1986, esta estrategia vuelve a ser retomada fuertemente en el periodo abordado. En el marco de la realización de un Trabajo Final de Grado se propone un abordaje cualitativo de análisis documental de normativas e informes de organismos públicos para recorrer las sucesivas tomas de posición del Estado Fueguino desde la declaración de la Emergencia Forestal en el año 2004. A partir de lo cual, de acuerdo a la hipótesis de este trabajo, es posible observar una direccionalidad hacia el agregado de valor, mediante el fortalecimiento de diversos espacios de gobernanza de los recursos naturales cuyo objetivo es hacer más sostenible el sector foresto-industrial.
El fin de la divulgación
Authors: Sánchez Mora Ana María
Published: May 2019

Es necesario reconocer que dentro de la ahora llamada comunicación pública de ciencia conviven posturas, objetivos, actores y actividades muy diversos; sin embargo, las más recientes manifestaciones de la actividad han eliminado prácticamente a la ciencia de su discurso al tiempo que limitan su finalidad a influenciar la agenda pública. La preponderancia de esta visión en detrimento de otras manifestaciones, en parte debido al ascendiente académico, podría llevar a la pérdida de diversidad en la comunicación de la ciencia, y en particular a menospreciar la divulgación, un género original y complejo que comunica la ciencia de la mano de lo literario.
Predicting Alzheimer's Disease Onset
Authors: Zeliger Harold I.
Published: May 2019

Recently, a method for assigning the probability of disease onset to all people, those clinically ill as well as those without prevalent disease has been described and termed the Oxidative Stress Index (OSI). The OSI, as originally formatted, does not predict which disease will more likely develop, only that further disease is predicted with increased OSI. It is hypothesized here that the OSI may be used to demonstrate which parameters are more contributory to the onset of a particular disease if it is measured at the time of onset of that disease. To test this hypothesis, the OSI has been reformatted to serve in that capacity for Alzheimer's disease (AD) with the anticipation that the OSI could serve to predict not only the likelihood of onset, but also identify those parameters that are most contributory to AD.

Published: May 2019

O presente artigo apresenta uma análise acerca do Programa Tempo Juvenil, proposta do Estado da Bahia para a educação de jovens e adultos na faixa etária dos 15 aos 17 anos. Discutimos quais os elementos que compõem a proposta e o conceito de currículo nela presente. Para isso, valemo-nos de conceitos da teoria sociológica de Basil Bernstein. O texto da proposta curricular é analisado como documento do Campo Recontextualizador Oficial (CRO). As conclusões apontam que o currículo está organizado em eixos temáticos e temas geradores, possui uma classificação diferente do ensino seriado e é compatível com um currículo do tipo integrado.

A partir do depositário nacional de teses e dissertações e bases de periódicos escolhidos foi possível identificar quarenta e duas produções acadêmico-científicas que investigam a eficácia-escolar e/ou o efeito-escola, sendo a maioria veiculadas por meio de dissertações e artigos científicos. Os estudos de casos que enfocam a relação entre organização, gestão escolar e clima acadêmico em face aos efeitos na aprendizagem dos alunos representam uma tendência dos estudos na área.
Paradigmas da intervenção e pedagogia social
Authors: Vieira Ricardo Manuel das Neves , Vieira Ana Maria de Sousa Neves
Published: May 2019

Face ao modelo clássico de intervenção social que parte do diagnóstico com vista à resolução de “problemas sociais”, aproximando-se do trabalho do médico, pelo que tantas vezes é classificado de paradigma biomédico, emerge, hoje, um modelo alternativo mais preocupado com a mudança, transformação, educação e autonomização dos sujeitos e comunidades intervencionadas, aqui designado de intervenção socioeducativa, assente na Pedagogia Social e na mediação intercultural. O texto começa por apresentar os paradigmas clássicos da mudança socioeducativa, tece críticas à intervenção social paliativa e assente em diagnósticos realizados por especialistas sem recurso à voz dos sujeitos, e termina apontando para uma intervenção social mediadora e empoderadora assente na Pedagogia Social e na mediação intercultural como pilares fundamentais da Educação Social.
A educação social ao serviço das trajetórias dos indivíduos e das comunidades
Authors: Samagaio Florbela
Published: May 2019

Considerando as transformações sociais ocorridas no século XIX, este artigo propõe um olhar cruzado entre a Pedagogia Social e a Sociologia na construção do conhecimento sobre a intervenção socioeducativa, cujo domínio de atuação tem vindo a ganhar terreno enquanto prática de trabalho social nos últimos anos em Portugal. Neste sentido, o artigo procura apresentar a Educação Social como uma prática de trabalho única e original, partindo das problemáticas sociais singulares, conjugando as perspetivas social e educativa num olhar diferenciador face às mesmas. Procura-se salientar a potencialidade da Educação Não Formal na conceção de políticas educacionais inovadoras na medida em que se ajustam às exigências sentidas no (i)mediato no contexto das realidades sociais. Destaca-se fundamentalmente o caráter dinâmico inerente à prática socioeducativa para o qual se convoca a noção de trajetória de mudança ao serviço dos indivíduos e das comunidades.

Desafios do envelhecimento populacional
Authors: Loureiro Armando Paulo Ferreira
Published: May 2019

O envelhecimento populacional é um facto social. Tal faz com que vários desafios se coloquem e se procure dar-lhes resposta em diversos setores. O da educação é um deles. Como bem sabemos, este é um setor que normalmente se tem dedicado à educação de tipo escolar e, dentro desta, a faixas etárias mais jovens. Ou seja, a tendência das políticas e da própria investigação tem recaído nessa parte da educação. No entanto, há uma outra educação que tem cada vez maior relevo na nossa sociedade e sobre a qual é necessário intensificar a reflexão e o investimento político e científico. Neste artigo procura-se dar um pequeno contributo no sentido de reforçar o relevo que a educação permanente de caráter não formal tem junto da população idosa.

Published: May 2019

Numa sociedade e numa economia que recorre cada vez mais ao digital e que disponibiliza o conhecimento pela tecnologia, o domínio de competências digitais é importante para a promoção da inclusão social. Tendo esta problemática como foco, a pesquisa identifica contextos e usos de tecnologias digitais nos processos de aprendizagem ao longo da vida de adultos em situações de vulnerabilidade social e potenciais efeitos para a inclusão social a partir da análise de artigos alojados na base de dados EBSCOhost, publicados em revistas académicas entre 2012 e 2017. A análise revela como mais referenciados os contextos de formação, seguindo-se a tecnologia/ferramentas usadas, com destaque para a aprendizagem online, dispositivos móveis e aplicações offline. Menos referenciadas são as práticas pedagógicas e os formandos envolvidos nas aprendizagens, essenciais para a inclusão social.
