Site–Year Characteristics Have a Critical Impact on Crop Sensor Calibrations for Nitrogen Recommendations
Authors: Colaço A.F. , Bramley R.G.V.
Published: May 2019

Core Ideas

Reflectance sensors are often calibrated to predict yield potential and crop nitrogen response.

Site–year characteristics affect crop sensor calibrations.

Univariate sensor models (e.g. those focused solely on normalized difference vegetation index) derived from multi site–year experimentation can have low accuracy.

Soil moisture and crop sensor information should be combined for more holistic calibrations.

Sensor‐based approaches to delivering nitrogen (N) fertilizer recommendations often rely on field experimentation to build calibrations between sensor readings and particular crop variables of interest. One important question is the extent to which calibrations derived from specific locations in specific seasons can be confidently extrapolated to other locations in future seasons. In this study, we examined a dataset covering 19 yr of wheat (Triticum aestivum L.) yield potential and crop N response calibrations to help answer two questions. First, what drives the variability in sensor calibration between different years? Second, what are the consequences of seasonal variability for the accuracy of sensor predictions and N recommendations? Deep soil moisture information, measured between 50 and 90 d after sowing, helped to explain the variability in the R2 and equation coefficients of yield potential and response index sensor calibrations between years. When data from multiple experimental years were combined to build generalized models, the R2 was quite low (∼0.25 for all 19 yr of data). Consequently, the benefit of the N rates recommended by the sensor over a conventional application based on historical optimum N rates was insignificant. We suggest that, rather than increasing experimental years indiscriminately, the relevant seasonal covariates should be incorporated into the sensor predictions in order build holistic sensor models. The results also highlight the likelihood that relevant site‐specific information, such as soil moisture status, may also explain between‐site variation in sensor calibration and so promote an enhanced ability to extrapolate calibrations from one location to another.

Core Ideas

Wheat simulations occurred in over 2000 site–years for semiarid and subhumid climates.

Limited transpiration trait increased wheat yield in 12 g m−2 in semiarid climate.

Root exploration traits improved wheat yield by 60 g m−2 in semiarid climate.

Faster leaf development trait increased wheat yield by 21 g m−2 across the entire study‐region

Genetic variability exists for the above traits for breeding programs to explore.

Genetic variability exists for plant traits that confer drought tolerance to wheat (Triticum aestivum L.); however, there are limited quantitative assessments on the long‐term effects of these traits on wheat yield. As some of these traits might be detrimental in wet years, our objectives were to assess predicted winter wheat yield gains resulting from six altered traits in a moist subhumid to semiarid climate transition area. We used a mechanistic crop simulation model and daily weather data for 30 consecutive years at semiarid (n = 27), dry‐ (n = 23) and moist‐subhumid (n = 18) locations in the US Southern Great Plains. Modified traits were limited transpiration rate under elevated vapor pressure deficit, deeper root system, faster root development, early or late stomata closure in response to soil drying, faster or slower leaf area development, and shorter vegetative cycle. Probability of water‐deficit, defined as fraction of transpirable soil water (FTSW) < 0.3 (i.e., limiting to transpiration), was 0.1 and 0.9 for the moist subhumid and semiarid environments, respectively. Increased root depth and rate of root development resulted in 35.5 to 87.3 g m−2 yield increases and probabilities of yield gain > 0.7 in dry subhumid and semiarid environments. Faster leaf area development resulted in probabilities of yield gain > 0.85 in subhumid environments. Limited transpiration rate increased grain yield by 12 g m−2 in semiarid environments. Neutral traits were early‐ and late‐stomatal closure in response to soil drying, reduced length of vegetative cycle, and slow rate of leaf area development.

Core Ideas

Cover crops improve soil microbial biomass compared to no cover crop and influence soil microbial community structure.

Soil microbial communities change both spatially and temporally.

Results of the study imply that integration of CC in a regular corn–soybean rotation can improve soil quality and environmental benefits.

Although cover crops (CC) are believed to play a major role in soil quality improvement, the effects of CC on microbial populations and community structure is not well understood. The objective of this study was to quantify CC effects on soil microbial biomass and community structure under a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation. The study was conducted at the Chariton County Cover Crop Soil Health Research and Demonstration Farm (CCSH) in Missouri, USA, where CC were first established in 2012. Soils were sampled in 2016, 2017, and 2018 from the 0‐ to 10‐cm depth layer using a grid sampling design and phospholipid fatty acid (PLFA) profiles were determined. Microbial biomass and microbial community structure (total fungi, total bacteria, rhizobia, gram (−), and actinomycetes biomass), as estimated from the PLFA biomarkers, were significantly greater (P < 0.05) in the CC treatment compared to no cover crop (NCC) in 2016 and 2018 (2.4‐ and 1.7‐fold larger, respectively). Within the CC treatment, differences by soil type were also observed, finding that the silt loam soil supported greater total microbial biomass than the loam soil in 2018. Spatial distribution patterns of total microbial biomass, bacteria biomass and fungi biomass differed with time. Overall, this study demonstrated that the CC treatment affected the soil microbial community biomass and structure, which has potential environmental, production, and soil quality benefits.

Published: May 2019

Diets of West African (WA) smallholder farmers are built on pearl millet [Pennisetum glaucum (L.) R. Br.]. Sustainable pearl millet hybrid breeding is challenging in WA, mostly due to an extensive genetic diversity combined with a high degree of admixture. In the absence of natural heterotic groups, understanding combining ability patterns can enable systematic development of heterotic groups and make sustainable hybrid breeding feasible. The objectives of this study were to evaluate heterosis and combining ability patterns and their relationship with genetic distance among WA pearl millets based on population hybrids, and to derive conclusions for future breeding programs. Therefore, 17 open‐pollinated varieties (OPVs) were crossed in a diallel mating design and tested together with their offspring in nine environments over 2 yr in Niger and Senegal. Genetic distances between the OPVs were evaluated with twenty microsatellite markers. Average panmictic better‐parent heterosis (PBPH) was 18% (1–47%) for panicle yield. A principal coordinate analysis based on genotyping results separated parental OPVs clearly by geographic origin. Although there was no relationship between genetic distance among OPVs and PBPH, we confirmed good combining ability among selected OPVs from Niger vs. Senegal. The identified cultivars (Nigerien CIVT, H80‐10Gr, and Taram and Senegalese Thialack 2 and Souna 3) with high combining ability are recommended for founding divergent heterotic pools targeting long‐panicle pearl millet hybrids. Our study shows the benefits of population hybrids and represents an important step to identify combining ability patterns and initial heterotic groups for WA pearl millet hybrid breeding.
Soil Nitrogen and Greenhouse Gas Dynamics in a Temperate Grassland under Experimental Warming and Defoliation

Published: May 2019

Core Ideas

Warming but not defoliation increased short‐term N mineralization.

The CO2efflux initially increased with warming and defoliation but promptly stabilized.

Warming and defoliation reduced N2O emissions but not when combined.

Soil responses to warming were complex and transient in this temperate grassland.

Grasslands are important for C storage and supporting livestock production, yet little is understood about how warming interacts with defoliation to alter soil C and N dynamics. We examined how increased growing season temperature and defoliation influenced soil microbial biomass C (MBC) and N (MBN), N mineral dynamics, and greenhouse gas (GHG) flux within the top 15 cm of mineral soil in a northern temperate grassland of Alberta, Canada. We performed a 2‐yr experiment with open‐top chambers to increase soil temperatures, with warming assessed alone and combined with a single intense midsummer defoliation treatment. Soil MBC and MBN did not respond to warming or defoliation (P> 0.05). Warming increased soil nitrification and net N mineralization in the spring of the second growing season (P< 0.05) but did not persist beyond May. Although warming and defoliation both increased CO2efflux separately during the first growing season (P< 0.05), the combination of these treatments reduced CO2efflux to levels similar to the controls, with no lasting effects into the following growing season. Warming also interacted with defoliation to increase N2O flux in the second growing season relative to plots under either warming or defoliation treatment, whereas CH4uptake was not influenced by our treatments. These results show the complex but transient impacts of warming and defoliation on soil C and N, particularly GHGs. Further research is needed to understand how these northern temperate grasslands respond to long‐term factorial experiments involving warming, defoliation, and variation in other factors (e.g., precipitation).
Simulation of Channelized Gas Flow Pattern in Heterogeneous Porous Media: A Feasibility Study of Continuum Simulation at Bench Scale
Authors: Samani Shirin , Geistlinger Helmut
Published: May 2019

Core Ideas

A continuum model can predict quantitative and qualitative properties of gas flow patterns.

Correlated spatial variability can capture dynamic features of gas flow channels.

Connectivity metrics, like Euler number, provide a practical method for quantifying gas channels.

In remediation technologies, air or O2 gas is injected into a polluted aquifer to remove organic contaminants. A gas injection process is also applied in enhanced oil recovery and CO2 sequestration. The wide range of gas injection processes into porous media necessitates accurate gas flow modeling. The focus of this study was to determine whether a continuum model with stochastic parameters can represent the properties of gas flow patterns. We applied stochastic heterogeneity in TOUGH2 simulation and used the experimental observations to validate simulation results. We created two types of stochastic heterogeneity: correlated heterogeneity, generated by an assigned covariance function, and uncorrelated heterogeneity, which distributes uniformly. We used Euler characteristics to quantify the gas channel properties and to determine whether the heterogeneity applied in a continuum model can represent gas channel properties. The results of this investigation confirm that the continuum model, which includes correlated heterogeneity, can predict the quantitative properties of gas flow, such as gas volume. Also, it can create gas channels that have Euler characteristics close to those obtained by experimental observation. In conclusion, the continuum model can predict the properties of gas flow if the spatial variability and correlation structure of the characteristic properties applied to the model are representative of the medium.

Published: May 2019

The aim of this study was to compare diagnostic techniques for the assessment of cartilage damage in the carpal and fetlock joints in horses with arthritis. The techniques compared were synovial fluid analysis, as well as radiographic, thermographic, ultrasonographic, and arthroscopic examinations. Sixteen horses of both sexes with arthritis, weighing 438 + 51 kg and at different ages were used as material. Before a detailed examination, an evaluation of the conformation and symmetry of the musculoskeletal system was performed. Nerve blocks definitively localized lameness to a specific site. Thermographic, radiographic, ultrasonographic, and arthroscopic examinations were performed after routine clinical examination. Synovial fluid and sera were collected for further analysis. In conclusion, although all examination techniques may yield useful information, their severe limitations were revealed, particularly in the detection of early articular cartilage damage. Arthroscopy is more reliable than other methods in cases of joint capsule lesions and intra-capsular lesions, as well as cartilage and synovial hyperplasia. Arthroscopy is considered to be advantageous and necessary.

Published: May 2019

The purpose of this study was to evaluate the effects of ketoprofen (KTP), flunixin meglumine (FLM), and meloxicam (MLX) administration on acute-phase proteins after dehorning in Holstein heifers. A total of 21 Holstein heifers were enrolled into three groups of equal size (n=7) and administered ketoprofen, flunixin meglumine, or meloxicam, at doses of 2.2 mg/kg, 1.1 mg/kg, and 1 mg/kg body weight, respectively. Serum amyloid A, haptoglobin, and ceruloplasmin levels were determined before the administration of the three drugs (0 hrs) and at 6, 12, 24, 48, and 96 hours post-administration. The mean values (±SD) obtained revealed no significant alteration in APP levels at 0 hrs in any of the three groups. Time-dependent alterations, however, were significant in all groups. Group-time interactions were significant (P < 0.001) for ceruloplasmin concentrations, whereas results for serum amyloid A and haptoglobin levels were deemed non-significant. Inter-group interaction revealed no significant findings regarding serum amyloid A and ceruloplasmin levels, but haptoglobin levels showed a significant difference between the KTP and FLM groups at 48 hrs. It may therefore be reasonably suggested that KTP, FLM, and MLX could all be administered to effect slight changes in acute phase proteins.

Published: May 2019

Based on the typical start and stop conditions of aeroengine high pressure rotor, the problem of flow-thermo-elastic coupling is solved in this research. Applying basic theory and control equation, it is analyzed the fields of transient temperature, thermal stress and thermal deformation in the start and stop process. Then the temperature at last stopping moment is selected as the boundary condition. With the flow-thermo-elastic coupling method, the distributions of air flow, heat transfer and temperature are discussed in high pressure rotor cavity. The results show the rotor has a higher temperature, and the density of temperature contour is much larger at the beginning of stop period. The temperature of each node gradually decreases as stop time increases. When the stop time is within 40-90 minutes, temperature difference between the upper and lower surfaces is larger than 20 °C. The distribution of transient temperature is different when restart process is taken at different stop moments. If the stop time is short, temperature distribution of the rotor is decreased firstly, then increased, and finally decreased. The time corresponding to the lowest temperature is also different in each node. It is the longest in the 3rd disk, and the shortest in the 8th disk.

Nowadays the role of green manufacturing (GM) in sustainable development is evident and irrefutable therefore organizations seek to introduce themselves green in order to maintain their image toward their community. The usual method of sustainability and greenness assessment of a system is making use of indicators and indexes which are classified into several groups based on their characteristics. An important type of index categorization is based on four sustainability attributes including economic, energy, environment and recourses as well as pressure-state-response model (PSR). Because of the research gap about interactions relationships on indexes and investigating their influence others and influence by others. Since, indexes in each group could be effective on other indexes and be overlapped to some extent, it is necessary to prioritize and evaluate cause and effect relations by use of an appropriate method. We consider the relationship and prioritize most important indexes to evaluate manufacturing' greenness based on aforementioned sustainability attributes and PSR model. Purpose data is gathered by survey GM experts questionnaires, including 41 indexes plus 4 mentioned attributes, totally as 45 factors in 13 groups. In order to data analysis, with respect to the non-certainty and insufficient information, Grey DEMATEL method is used.

Anti-Inflammatory Properties of Plant Derived Natural Products – A Systematic Review
Authors: Allijn Iris E. , Brinkhuis René P. , Storm Gert , Schiffelers Raymond M.
Published: May 2019

Traditionally, natural medicines have been administered as plant extracts, which
are composed of a mixture of molecules. The individual molecular species in this mixture
may or may not contribute to the overall medicinal effects and some may even oppose the
beneficial activity of others. To better control therapeutic effects, studies that characterized
specific molecules and describe their individual activity that have been performed over the
past decades. These studies appear to underline that natural products are particularly effective
as antioxidants and anti-inflammatory agents. In this systematic review we aimed to identify
potent anti-inflammatory natural products and relate their efficacy to their chemical structure
and physicochemical properties. To identify these compounds, we performed a comprehensive
literature search to find those studies, in which a dose-response description and a positive
control reference compound was used to benchmark the observed activity. Of the analyzed
papers, 7% of initially selected studies met these requirements and were subjected to further
analysis. This analysis revealed that most selected natural products indeed appeared to possess
anti-inflammatory activities, in particular anti-oxidative properties. In addition, 14% of the
natural products outperformed the remaining natural products in all tested assays and are attractive
candidates as new anti-inflammatory agents.
Far Infrared-assisted Sample Extraction and Solvent Removal for Capillary Electrophoretic Determination of the Bioactive Constituents in Citri Reticulatae Pericarpium
Authors: Zhang Yan , Zhang Luyan , Chen Gang
Published: May 2019

Background:

Sample preparation is crucially important for the capillary electrophoretic
measurement of the bioactive constituents in Citri Reticulatae Pericarpium because conventional
solvent extraction is time-consuming and the solvent peaks seriously interfere with the measured
capillary electropherograms.

Objective:

The objective of the present study is to establish far infrared-assisted sample preparation
approaches for the analysis of Citri Reticulatae Pericarpium.

Methods:

Synephrine and hesperidin in Citri Reticulatae Pericarpium were determined by capillary
electrophoresis in combination with far infrared-assisted sample extraction and solvent removal.

Results:

The effects of detection potentials, irradiation times and the voltages applied to the infrared
generator were investigated to acquire the optimal assay conditions. Synephrine and hesperidin
could be well separated within 6 min at a separation voltage of 9 kV in an alkaline borate solution.
Satisfactory linearity was observed over the concentration range of 0.001 to 1 mM with the detection
limits of 0.43 and 0.52 μM for synephrine and hesperidin, respectively. The results exhibited
that far infrared irradiations could enhance the efficiencies of sample extraction and solvent removal
during the sample preparation of Citri Reticulatae Pericarpium. The extraction time was
significantly reduced to 6 min while the interference of the solvent peaks towards the electropherograms
was eliminated.

Conclusion:

Far infrared-accelerated extraction and solvent removal were employed in the capillary
electrophoretic determination of the bioactive constituents in Citri Reticulatae Pericarpium
with satisfactory results. The ease, simplicity, efficiency and low cost of the novel sample preparation
approaches indicate they may find a wide range of applications.
Coreceptor-Based Hematopoietic Stem Cell Gene Therapy for HIV Disease

:

Combination antiretroviral therapy (cART) has significantly reduced the mortality rate and
morbidity, and has increased the life expectancy of the human immunodeficiency virus (HIV) infected
patients. However, the current cART is incapable of eradicating viruses from the human body, and HIV
remains one of the most notorious viruses mankind has ever faced. HIV-1 enters target cells through the
binding of gp120 viral protein to a CD4 receptor and then to a coreceptor, C-C chemokine receptor 5
(CCR5) or C-X-C chemokine receptor type 4 (CXCR4). Individuals homozygous for a 32-bp deletion
in the CCR5 allele, CCR5Δ32, are almost completely resistant to HIV-1 acquisition. Moreover, several
of natural CXCR4 mutants which have been identified can reduce HIV-1 entry without impairing either
ligand binding or signaling. In order to get rid of indefinite treatment for HIV patients, there is a growing
interest in creating an HIV-resistant immune system through the use of CCR5 and CXCR4-modified
hematopoietic stem cells (HSCs). Proof of concept for this approach has been provided in the instance
of “Berlin patient” transplanted with allogeneic stem cells from a donor with homozygosity for the
CCR5Δ32 deletion. Here, we review the progress of coreceptor-based HSC gene therapy for HIV disease
and present new strategies.
Implementation Science Research Examining the Integration of Evidence-Based Practices Into HIV Prevention and Clinical Care: Protocol for a Mixed-Methods Study Using the Exploration, Preparation, Implementation, and Sustainment (EPIS) Model (Preprint)
Authors: Idalski Carcone April , Coyle Karin , Gurung Sitaji , Cain Demetria , Dilones Rafael E , Jadwin-Cakmak Laura , Parsons Jeffrey T , Naar Sylvie
Published: May 2019

BACKGROUND

The Exploration, Preparation, Implementation, and Sustainment (EPIS) model is an implementation framework for studying the integration of evidence-based practices (EBPs) into real-world settings. The EPIS model conceptualizes implementation as a process starting with the earliest stages of problem recognition (Exploration) through the continued use of an EBP in a given clinical context (Sustainment). This is the first implementation science (IS) study of the integration of EBPs into adolescent HIV prevention and care settings.

OBJECTIVE

This protocol (ATN 153 EPIS) is part of the Scale It Up program, a research program administered by the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN), described in this issue by Naar et al. The EPIS study is a descriptive study of the uptake of 4 EBPs within the Scale It Up program. The goal of EPIS is to understand the barriers and facilitators associated with the Preparation, Implementation, and Sustainment of EBPs into HIV prevention and clinical care settings.

METHODS

The EPIS study is a convergent parallel mixed-methods IS study. Key implementation stakeholders, that is, clinical care providers and leaders, located within 13 ATN sites across the United States will complete a qualitative interview conducted by telephone and Web-based surveys at 3 key implementation stages. The Preparation assessment occurs before EBP implementation, Implementation occurs immediately after sites finish implementation activities and prepare for sustainment, and Sustainment occurs 1 year postimplementation. Assessments will examine stakeholders’ perceptions of the barriers and facilitators to EBP implementation within their clinical site as outlined by the EPIS framework.

RESULTS

The EPIS baseline period began in June 2017 and concluded in May 2018; analysis of the baseline data is underway. To date, 153 stakeholders have completed qualitative interviews, and 91.5% (140/153) completed the quantitative survey.

CONCLUSIONS

The knowledge gained from the EPIS study will strengthen the implementation and sustainment of EBPs in adolescent prevention and clinical care contexts by offering insights into the barriers and facilitators of successful EBP implementation and sustainment in real-world clinical contexts.

Consumer Liking and Descriptive Flavor Attributes of M. Longissimus Lumborum and M. Gluteus Medius Beef Steaks Held in Varied Packaging Systems
Authors: Ponce Jacqueline , Brooks J. Chance , Legako Jerrad F.
Published: May 2019

Sensory evaluation was conducted to investigate the impact of packaging system and muscle type on beef flavor. Beef M. Longissimus lumborum (LL) and M. Gluteus medius (GM) steaks were produced from vacuum packaged subprimals at 14 d postmortem. Steaks were placed in various packaging types and held for 7 d prior to 48 h of retail display under continuous fluorescent lighting. Packaging types included: high-oxygen modified atmosphere lidded trays (80% O2/20% CO2, HIOX), carbon monoxide modified atmosphere lidded trays (0.4% CO/30% CO2/69.6%N2, CO), rollstock (forming/non-forming films, ROLL), vacuum packaging (stored in darkness, VAC), and traditional overwrap (foam trays wrapped with polyvinyl chloride film immediately before display, OW). Steaks were evaluated after cooking by consumer panelists and a trained descriptive attribute panel. For consumer evaluation, a muscle × package type interaction (P = 0.040) occurred for juiciness. Overall liking, tenderness, and liking of flavor were influenced (P ≤ 0.003) by package type. Overall liking, liking of flavor, and tenderness of HIOX was lower (P < 0.05) than all other package types. Additionally, package type impacted (P ≤ 0.030) overall, flavor, and tenderness acceptability. Overall and flavor acceptability was the lowest (P < 0.05) for the HIOX treatment. From trained panel attribute evaluation, muscle × package type interactions were detected (P ≤ 0.021) for brown/roasted, bloody/serumy, and juiciness. Juiciness was the least (P < 0.05) desirable for GM HIOX compared to all other muscle and package type combinations. Steaks from HIOX packages had the highest (P < 0.05) ratings for oxidized and cardboardy, and were rated lowest (P < 0.05) in beef flavor ID and umami compared with all other package types. The LL had greater (P < 0.05) beef flavor ID, fat-like, umami, sweet, and overall tenderness ratings than the GM. The GM was more (P < 0.05) liver-like and oxidized compared with the LL. These data indicate a high oxygen packaging environment has the potential to accentuate negative descriptive sensory attributes and lower consumer sensory scores, while diminishing palatability in both muscles.

The heterogeneity of students in Indonesia is a challenge for teachers today. Creativity is not only for students with high mathematical abilities, but also introduced to students who are in the slow learner category. This research is a qualitative descriptive study that aims to describe the level of creativity of the slow learner, and to describe how to develop creative thinking skills for slow learners. The subjects in this study from one of the schools in Yogyakarta whose students were included in the slow learner category. The subjects were selected by purposive sampling. Data collection had been done by giving problems solving to subjects, then interviewing them to clarify the answers that have been written. Data analysis had been stopped on the third subject because the data from the third subject was no difference with data from the previous subject. The results of this study indicate that slow learners are not able to show the three indicators of creativity in solving mathematical problems (fluency, flexibility, and novelty), so that the slow learners are classified as creative thinking skills level 0 or included in not creative students. Other findings indicate that one subject indicated being able to show one indicator of creativity, namely fluency, so that subject classified as level 1 (almost not creative).

To be able to hone students 'mathematical abilities, a learning model is needed that is appropriate to the students' character and the material being taught. One learning model that can improve student learning outcomes is the Contextual Teaching and Learning (CTL) model. The method used in this study is Classroom Action Research (CAR). Subjects in this study were fifth grade in Elementary School. The instruments used in this study were tests and observation sheets of teacher and student activities. Based on the analysis of research data, it is concluded that CTL can improve the ability of mathematical understanding of fraction concept for elementary students. Thus, the use of CTL learning models can be used as an alternative learning to be applied to learning mathematics in elementary school especially on learning concept of fractions.

The Florida tomato industry is facing challenges of increased production costs and decreased yields resulting from the methyl bromide (MBr) phase-out under the Montreal Protocol for environmental concerns. MBr and several accepted alternative soil fumigant systems are analyzed in this study from an economic perspective. This article focuses on identifying optimal fumigant systems by analyzing the cost effectiveness and economic risk associated with MBr and several other commercially available soil fumigant systems using data collected from scientific field trials. The results obtained show that a 67:33 formulation of MBr: chloropicrin is the most cost-effective treatment, and no alternative fumigant systems investigated can substitute MBr cost-effectively in Florida tomato production. The analysis indicated that switching from MBr (67:33) to the new industry standard PicChlor 60 approximately resulted in a loss of $3,569 per acre in gross revenue and $1,656 per acre in profit using market prices in the 2013/14 season. Higher market prices would further increase the loss.

Authors: Fuadzy Hubullah
Published: May 2019

Latar belakang: Kota Bandung merupakan wilayah endemik Demam Berdarah Dengue (DBD) tertinggi di Jawa Barat. Satu di antara faktor risiko peningkatan kasus DBD adalah infestasi Aedes aegypti di pemukiman penduduk. Infestasi Ae. aegypti tersebut dipengaruhi oleh tindakan masyarakat dalam melaksanakan 3M Plus di rumah tinggal. Penelitian yang membahas sumber informasi yang diperoleh masyarakat untuk meningkatkan pengetahuan DBD dan dampaknya terhadap tindakan PSN di Kota Bandung masih sangat terbatas. Tujuan: Penelitian ini bertujuan untuk menganalisis hubungan pengetahuan terhadap tindakan PSN Plus. Metode: Analisis ini merupakan lanjutan dari penelitian “penentuan faktor risiko sanitasi rumah tinggal pada kejadian demam berdarah dengue (DBD) di Kota Bandung”. Total data yang dianalisis adalah 783 responden. Tahapan analisisnya adalah pertama menentukan hubungan sumber informasi dengan tingkat pengetahuan responden mengenai DBD secara umum, kedua menentukan hubungan pengetahuan dengan tindakan PSN Plus, dan ketiga menentukan hubungan pengetahuan jenis kontainer dengan infestasi Ae. aegypti pradewasa. Hasil: Penelitian ini memberikan gambaran bahwa berbagai jenis sumber  informasi mengenai DBD dapat meningkatkan pengetahuan responden di Kota Bandung. Pengetahuan mengenai PSN Plus dapat meningkatkan 1,4 kali kebiasaan responden untuk melakukan tindakan menguras dan menutup kontainer air. Namun, tindakan tersebut belum mampu membasmi infestasi Ae. aegypti pradewasa pada kontainer air di rumah tinggal. Kesimpulan: Pengetahuan responden di Kota Bandung berhubungan dengan tindakan PSN plus tetapi belum mampu membasmi infestasi Ae. aegypti di rumah tinggal.

Plasmodium knowlesi was the fifth Plasmodium which can infect malaria into human. Even though it has already been identified since 1931, the first case of natural human infection was known in 1965. Knowlesi malaria spread among South East Asia where population of monkeys Macaca fascicularis, M. nemestrina, or Presbytis melalophos existed along with malaria vector Anopheles from leucosphyrus group. This review aimed to describe the diversity of P. knowlesi vector. We have done profound literature review on 6 articles from 219 articles related to P. knowlesi published within 2008 to 2015. Our study found that      P. knowlesi was recorded only in two countries; Malaysia and Vietnam. In Malaysia, Anopheles cracens, An. introlatus, An. latens, and An. balabacensis were found in Kuala Kapis Pahang, Hulu Selangor, Kapit Serawak, and Kudat Sabah, respectively. While in Vietnam, only a single species An. dirus found to be P. knowlesi vector. This review conclude that positive leucosphyrus mosquitoes most likely to be different among different region. The more abundance, the higher chance of mosquito species to become vector.

Published: May 2019

La teoría del marketing de la cultura se ha desarrollado desde una visión romántica del arte. Bajo este enfoque se considera que el marketing no puede ser aplicado durante la producción artística pues se corre el riesgo de que éste contribuya a su banalización en aras de alcanzar una mayor audiencia. Este trabajo expone las principales contribuciones del estudio del marketing de la cultura desde sus inicios en donde se sugería su uso como mera herramienta útil para incrementar los beneficios, hasta los actuales enfoques en donde se discute si este debe ser aplicado o no en el proceso de producción del arte. El objetivo es sistematizar la evolución que ha experimentado esta disciplina, y a partir de ello ofrecer argumentos a favor de la aplicación del marketing antes, durante y después del proceso creativo
