A Cross‐Validation of Statistical Models for Zoned‐Based Prediction in Cultivar Testing
Authors: Buntaran Harimurti , Piepho Hans‐Peter , Hagman Jannie , Forkman Johannes
Published: May 2019

The principal goals of a plant breeding program are to provide breeders with cultivar information for selection purposes and to provide farmers with high‐yielding and stable cultivars. For that reason, multi‐environment trials need to be done to predict future cultivar yield, and a robust statistical procedure is needed to provide reliable information on the tested cultivars. In Sweden, the statistical procedure follows the tradition of modeling cultivar effects as fixed. Moreover, the analysis is performed separately by zone and level of fungicide treatment, and so the factorial information regarding cultivar × zone × fungicide combinations is not explored. Thus, the question arose whether the statistical method could be improved to increase accuracy in zone‐based cultivar prediction, since the cultivar recommendation is zone based. In this paper, the performance of empirical best linear unbiased estimation (E‐BLUE) and empirical best linear unbiased prediction (E‐BLUP) are compared using cross‐validation for winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.), in single‐year and multiyear series of trials. Data were obtained from three agricultural zones of Sweden. Several linear mixed models were compared, and model performance was evaluated using the mean squared error of prediction criterion. The E‐BLUP method outperformed the E‐BLUE method in both crops and series. The prediction accuracy for zone‐based yield was improved by using E‐BLUP because the random‐effects assumption for cultivar × zone interaction allows information to be borrowed across zones. We conclude that E‐BLUP should replace the currently used E‐BLUE approach to predict zone‐based cultivar yield.

Published: May 2019

Multistage linear phenotypic selection indices predict the individual net genetic merit at different individual ages or stages and are cost‐saving strategies for improving several traits. In a two‐stage context, we compared the relative efficiency of the optimum multistage linear phenotypic selection index (OMLPSI) and the decorrelated multistage linear phenotypic selection index (DMLPSI) theory to predict the individual net genetic merit and selection response using a real and a simulated dataset. In addition, we described a method for obtaining the OMLPSI selection intensity in a two‐stage context. The criteria used to compare the relative efficiency of both indices were that the total selection response of each index must be lower than or equal to the single‐stage linear phenotypic selection index (LPSI) selection response, similar to the accuracy of each index to predict the net genetic merit. Using four different total proportions (p = 0.05, 0.10, 0.20, and 0.30) for the real dataset, the total DMLPSI selection response was 22.80% higher than the estimated single‐stage LPSI selection response, whereas the total OMLPSI selection response was only 2.21% higher than the estimated single‐stage LPSI selection response. In addition, at Stage 2, OMLPSI accuracy was 62.24% higher than the DMLPSI accuracy for predicting the net genetic merit. We found similar results for the simulated data. Thus, we recommend using OMLPSI when performing the multistage phenotypic selection.

Published: May 2019

Nutritive value of alfalfa (Medicago sativa L.) is limited by indigestible cell wall constituents, especially lignin. Commercially released genetically engineered alfalfa cultivars with reduced lignin (RL) concentration were developed recently by downregulation of the caffeoyl CoA 3‐O‐methyltransferase (CCoAOMT) enzyme in the lignin pathway. This research compared forage nutritive value and dry matter yield of a RL cultivar (‘HarvXtra‐008’) with non‐RL cultivars (‘54R02’ and ‘WL355RR’) across six states in the northern United States. A randomized complete block design with a split‐plot restriction on treatment randomization was used, where harvest intervals (28, 33, and 38 d) were assigned to whole plots and cultivars were the subplots. Harvest interval and cultivar effects were significant (P < 0.001) for all variables, and cultivars responded similarly across harvest intervals in that forage yield increased and nutritive value declined with increasing harvest interval. HarvXtra‐008 was consistently greater in forage nutritive value than non‐RL cultivars averaged across harvest intervals: it was 8.4% lower in acid detergent lignin, 3.5 to 7.5% lower in amylase‐treated neutral detergent fiber, and 5.3 to 7.7% greater in neutral detergent fiber digestibility, but 4.8 to 7.0% lower in dry matter yield. HarvXtra‐008 was slightly higher or similar in nutritive value and had similar or greater dry matter yield compared with non‐RL cultivars harvested on a harvest schedule 5 to 10 d earlier and more frequent. Thus, RL alfalfa can extend the time interval when it is possible to harvest forage with adequate fiber digestibility for animals with high energy requirements.

Core Ideas

Bray‐1, Mehlich‐3, Haney–Haney–Hossner–Arnold, and Olsen‐P were compared on primarily alkaline calcareous soils.

Mehlich‐3 was correlated with the Olsen‐P extractant regardless of pH or inorganic C content.

Soil P testing is critical to ensure the accuracy of fertilizer recommendations and to optimize crop yield while minimizing negative environmental consequences. Olsen‐P is the most commonly used soil P test for alkaline calcareous soils found in Idaho and the western United States. The Bray‐1 test is commonly used in the Pacific Northwest on neutral to acidic soils but underestimates P in alkaline calcareous soils. Mehlich‐3 has been evaluated throughout various regions in the United States. Few data evaluating Mehlich‐3 exist for soils in the western United States. Additionally, the comparatively newly developed Haney–Haney–Hossner–Arnold (H3A) test, a component of the soil health tool, has not been widely evaluated on alkaline calcareous soils. Soil samples from the 0‐ to 30‐cm depth were collected from agricultural fields throughout Idaho and analyzed with Bray‐1, H3A, Mehlich‐3, and Olsen‐P extractants. The results indicate that Olsen‐P was correlated with Mehlich‐3, whereas Bray‐1 and H3A were not correlated with Olsen‐P. Both Bray‐1 and H3A resulted in lower values of extractable P than the Olsen‐P test, whereas Mehlich‐3 resulted in greater values. A threshold point in CaCO3 (i.e., inorganic C) of 6.7 and 5.1 mg kg‐1 for the Bray‐1 and H3A was obtained, respectively, which indicated that inorganic C concentrations at or above these levels resulted in a reduction in extractable soil P. Thus Mehlich‐3 could be evaluated for use in alkaline calcareous soils, whereas Bray‐1 and H3A have notable issues that would limit their applicability.

Core Ideas

Chronic N enrichment increased N exports, although ecosystem N retention was still high.

Soil was the largest ecosystem N pool, but it was not significantly altered by chronic N enrichment.

Chronic N enrichment increased biomass N accumulation in hardwood but not in softwood stands.

We examine the temporal trend of input–output N fluxes and net ecosystem N retention, and estimate a mass balance for ecosystem soil and vegetation pools, after 25 yr of chemical manipulation at the Bear Brook Watershed in Maine (BBWM). The BBWM is a paired whole watershed manipulation experiment designed to study the effects of elevated N and S deposition on forest ecosystem function. Starting in 1989, 25.2 kg N ha−1 was added annually to the West Bear (treated) watershed. The N additions in West Bear stimulated N loss through stream exports, and West Bear retained 81% of the annual N inputs, compared to 94% retention in the reference, East Bear. After 25 yr of N additions, the West Bear watershed had accumulated ∼700 kg ha−1 more N than East Bear in soils and vegetation, with ∼10% of the accumulated N stored in forest biomass. The treatment increased recent biomass N accumulation rates in the hardwood stands, but not in the softwoods. Soils did not show detectable differences in total N content between watersheds, although the organic soils had greater N in West Bear. This paper presents a unique set of findings from one of the few long‐term whole forest ecosystem N enrichment studies in the world. While N dynamics were clearly altered in West Bear, with evidence of accelerated N cycling, the treated watershed did not attain an advanced stage of N saturation during the study period, based on the evidence from forest growth and stream N exports.
Removal of crystal violet dye by a novel adsorbent derived from waste active sludge used in wastewater treatment
Authors: Sahbaz Deniz Akin , Dandil Sahra , Acikgoz Caglayan
Published: May 2019

This study dealt with preparation of the activated carbon derived from active sludge as an adsorbent for the adsorption of crystal violet (CV) from aqueous solution. The waste active sludge was activated chemically with KOH and carbonized to get activated carbon with a large surface area and a high porosity. The activated carbon was characterized by Fourier transform infrared (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET) instrument, and scanning electron microscopy (SEM). Adsorption of CV from aqueous solution onto the activated carbon was investigated under varying conditions, such as adsorbent dosage (1–6 g/L), solution pH (4–9), contact time period (0–150 min), initial dye concentration (20–100 mg/L), and temperature (25–55 °C). 4.0 g/L of adsorbent dosage was chosen as the optimum level due to having a high removal rate (96.2%) (initial CV concentration 60 mg/L; 150 rpm; pH 6; 25 °C). The adsorption kinetic and adsorption isotherms were well described by the pseudo second order kinetic and the Freundlich isotherm model, respectively. The thermodynamic parameters indicated that the adsorption is a spontaneous process and favored at higher temperatures. The results show that the activated carbon derived from active sludge could be employed as a low-cost material for the removal of CV dye.

Authors: Pu Qiang , Kazemi Mosstafa , Mohammadi Masoud
Published: May 2019

Sulfoxides are key scaffolds in the synthesis of pharmaceutically active molecules. A large
number of sulfoxides are indispensable ingredients in the structure of most antibiotics, biological and
natural products such as Modafinil, Adrafinil, CRL-40,941 or fladrafinil, Fipronil, Oxydemetonmethyl,
Omeprazole, Pantoprazole, Lansoprazole and Rabeprazole. The oxidation of sulfides is the
most common and efficient strategy for the preparation of sulfoxides. Recently, many protocols
based on using transition metals have been reported for the oxidation of sulfides to the sulfoxides. In
this paper, we summarized a nice category of the reported protocols in the literature for the oxidation
of sulfides to sulfoxides.

Efficient Dynamic Resource Allocation in Hadoop Multiclusters for Load- Balancing Problem
Authors: S. Karthikeyan , Seetha Hari , R. Manimegalai
Published: May 2019

Background:

‘Map-Reduce’ is the framework and its processing of data by rationalizing
the distributed servers. also its running the various tasks in parallel way. The most important problem
in map reduce environment is Resource Allocation in distributed environments and data locality
to its corresponding slave nodes. If the applications are not scheduled properly then it leads to
load unbalancing problems in the cloud environments.

Objective:

This Research suggests a new dynamic way of allocating the resources in hadoop multi
cluster environment in order to effectively monitor the nodes for faster computation, load balancing
and data locality issues. The dynamic slot allocation is explained theoretically in order to address
the problems of pre configuration, speculative execution, delay in scheduling and pre slot allocation
in hadoop environments. Experiment is done with Hadoop cluster which increases the efficiency
of the nodes and solves the load balancing problem.

Methods:

The Current design of Map Reduce Hadoop systems are affected by underutilization of
slots. The reason is the number of maps and reducer is allotted is smaller than the available number
of maps and reducers. In Hadoop most of the times its noticed that dynamic slot allocation policy,
the mapper or reducers are idle. So we can use those unused map tasks to overloaded reducer tasks
in-order to increase the efficiency of MR jobs and vice versa.

Results:

The real time experiment was implemented with Multinode Hadoop cluster map reduce
jobs of file size 1giga bytes to 5 giga bytes and various performance test has been taken.

Conclusion:

This paper focused on Hadoop map reduce resource allocation management techniques
for multi cluster environments. It proposes a novel dynamic slot allocation policy to
improve the performance of yarn scheduler and eliminates the load balancing problem. This
work proves that dynamic slot allocation is outperforms more than yarn framework. In future
it considered to concentrate on CPU bandwidth and processing time.

O segundo trata da relação entre políticas regulatórias e a defesa da concorrência, sobretudo por conta da adoção de várias medidas por parte das agências reguladoras com o objetivo de promover concorrência, sendo o maior exemplo as políticas de portabilidade. O terceiro e último bloco estimula o aluno a estudar a interação entre inovação e defesa da concorrência, de forma a avaliar se os instrumentos tradicionais utilizados em atos de concentração e condutas anticompetitivas se aplicam ou não a mercados caracterizados por alta tecnologia.
O FENÔMENO DA ILICITUDE LUCRATIVA
Authors: Fortes Pedro Rubim Borges
Published: May 2019

O presente artigo discute o fenômeno da ilicitude lucrativa. Como as empresas privadas tomam decisões racionais sobre a violação das leis consumeristas e a observação empírica mostra que as empresas brasileiras continuam violando o Código de Defesa do Consumidor (CDC), o sistema de tutela coletiva não consegue prevenir essas irregularidades devido à insuficiência de sanções. Analisando todas as 405 ações coletivas movidas contra empresas privadas pelas Promotorias de Justiça de Tutela Coletiva de Defesa do Consumidor da Capital no Ministério Público do Estado do Rio de Janeiro, entre 1991 e 2010, as sanções impostas pelos juízes não foram suficientes para prevenir novas transgressões coletivas. Os tribunais brasileiros não devem apenas condenar essas empresas por suas violações dos direitos do consumidor, mas também impor sanções econômicas e obrigá-las a reembolsar efetivamente as tarifas ilegais que cobraram de forma abusiva. Os danos punitivos devem ser ótimos, dissuadindo as empresas sem causar custos excessivos que possam prejudicar acionistas e consumidores. A ilicitudade não deve ser lucrativa. No cenário atual de dissuasão imperfeita, as instituições financeiras, as empresas de telecomunicações e outras empresas privadas continuarão a infringir a lei, uma vez que tenham incentivos econômicos para fazê-lo.
A Virtual Counseling Application Using Artificial Intelligence for Communication Skills Training in Nursing Education: Development Study (Preprint)
Authors: Shorey Shefaly , Ang Emily , Yap John , Ng Esperanza Debby , Lau Siew Tiang , Chui Chee Kong
Published: May 2019

BACKGROUND

The ability of nursing undergraduates to communicate effectively with health care providers, patients, and their family members is crucial to their nursing professions as these can affect patient outcomes. However, the traditional use of didactic lectures for communication skills training is ineffective, and the use of standardized patients is not time- or cost-effective. Given the abilities of virtual patients (VPs) to simulate interactive and authentic clinical scenarios in secured environments with unlimited training attempts, a virtual counseling application is an ideal platform for nursing students to hone their communication skills before their clinical postings.

OBJECTIVE

The aim of this study was to develop and test the use of VPs to better prepare nursing undergraduates for communicating with real-life patients, their family members, and other health care professionals during their clinical postings.

METHODS

The stages of the creation of VPs included preparation, design, and development, followed by a testing phase before the official implementation. An initial voice chatbot was trained using a natural language processing engine, Google Cloud’s Dialogflow, and was later visualized into a three-dimensional (3D) avatar form using Unity 3D.

RESULTS

The VPs included four case scenarios that were congruent with the nursing undergraduates’ semesters’ learning objectives: (1) assessing the pain experienced by a pregnant woman, (2) taking the history of a depressed patient, (3) escalating a bleeding episode of a postoperative patient to a physician, and (4) showing empathy to a stressed-out fellow final-year nursing student. Challenges arose in terms of content development, technological limitations, and expectations management, which can be resolved by contingency planning, open communication, constant program updates, refinement, and training.

CONCLUSIONS

The creation of VPs to assist in nursing students’ communication skills training may provide authentic learning environments that enhance students’ perceived self-efficacy and confidence in effective communication skills. However, given the infancy stage of this project, further refinement and constant enhancements are needed to train the VPs to simulate real-life conversations before the official implementation.

The data used for this article originate from a database compiled from the Handboek voor cultuuren handelsondernemingen in Nederlandsch-Indië (Handbook for cultivation and trading companies in the Netherlands Indies) and will also be incorporated into my PhD dissertation entitled ‘Foreign investment and colonial economic growth in Indonesia’, which forms part of the larger research project ‘Foreign capital and colonial development in Indonesia’.
“Saudagar Bandoeng”, 1906—1930-an
Authors: Rohayati Dede
Published: May 2019

The growth of Bandung as a city at the beginning of the 20th century, has produced urban groups that dominate parts of the urban economy. One group was known as Saudagar Bandoeng or the Bandung indigenous Muslim merchants. They started growing as middle-class urban Muslims who rely on their economic life in the commercial sector. There are three reasons for the emergence of Saudagar Bandoeng, namely the rejuvenation of Pasar Baru market in 1906, the rise of batik trading and the modernization of Bandung facilitated the traffic goods and people to and from the city of Bandung. The Saudagar Bandoeng emerged as a community of santri traders which were relatively different from that of rural santri traders. The birth of the Soedara Association (Himpoenan Soedara) as an organization for santri traders to promote indigenous economic sector in Bandung represented one of the rise of merchant nationalist identity as has been seen in other cities such as Surakarta.

Big demands of women have given them freedom to participate in the works, choosing professions in the movie industry based upon their respective passion. In the development, they began to be driving forces of the expansion of public spaces for women in their locality, especially within the movie industry. These actresses were promoted intensively as a way to legitimate commercial movies. Apart from earning proper wages, they also were widely exposed but also objectified.
Pembentukan Identitas Sosial Komunitas Hadhrami di Batavia Abad XVIII-XX
Authors: Athoillah Ahmad
Published: May 2019

This paper discusses the process of forming identities carried out by the Hadhrami community in Batavia throughout the late 18th century until the beginning of the 20th century. The taking of the topic was motivated by the strong social identity of the Hadhrami community in Batavia, especially in religion and economy since the 19th century to the present. The problem of this research is about the form and process of forming Hadhrami social identity from the end of the 18th century to the beginning of the 20th century. To answer these problems, a critical historical method is used by using various historical sources and relevant reference studies.Some of the results obtained from this study are various historical realities, such as the formation of social religious symbols including mosques and religious teaching forum. Some important things are the formation of economic identities such as wholesale trade, shipping businesses and property businesses. In addition, there were also shifting settlements from Hadhrami over the Koja people in Pekojan in the early 19th century, as well as the shift of the Hadhrami to the inland of Batavia in the late 19th century. These various realities ultimately affected various forms and processes of forming the social identity of the Hadhrami community, such as the material aspects, language, behavior, and collective ideas of the Hadhrami community especially at the beginning of the 19th century. Generally the Hadhrami community had transformed themselves and their collective parts into colonial society in Batavia until the beginning of the 20th century.

Hamiltonisation, measure preservation and first integrals of the multi-dimensional rubber Routh sphere
Authors: García-Naranjo Luis
Published: May 2019

We consider the multi-dimensional generalisation of the problem of a sphere, with axi-symmetric mass distribution, that rolls without slipping or spinning over a plane. Using recent results from Garc?a-Naranjo [21] and Garc?a-Naranjo and Marrero [22], we show that the reduced equations of motion possess an invariant measure and may be represented in Hamiltonian form by Chaplygin?s reducing multiplier method. We also prove a general result on the existence of first integrals for certain Hamiltonisable Chaplygin systems with internal symmetries that is used to determine conserved quantities of the problem.

Authors: Djurickovic Mirjana , Ivanovic Mirjana
Published: May 2019

Background/Aim. The number of children with diabetes is constantly
increasing. The aim of this study was to evaluate oral health in children
with type 1 diabetes mellitus compared to healthy children. Methods. The
study included 177 patients aged 10-15 years, divided into two groups. Group
T1DM, made up of children with type I diabetes mellitus. Control group was
healthy children. The dental health was assessed using the DMFT index. The
Plaque Index (PI) according to Silness-L?e and the Calculus Index (CI) by
Green were used to determine oral hygiene. Salivary status involved
determining the amount of secreted stimulated saliva and buffer capacity of
the same patient. Results. In terms of average values of DMFT index of
permanent teeth, there were no statistically significant differences in study
groups. A significant difference in PI value in group T1DM (1.29 ? 0.56) and
control group (1.01 ? 0.50) was observed (p =0.001). Also, a significant
difference in CI value in group T1DM (0.09 ? 0.23) and in control group (0.03
? 0.14) was observed (p=0.047). The average amount of secreted stimulated
saliva for diabetic children was significantly lower (0.99 ? 0.14 ml/min),
compared to healthy children (1.06 ? 0.20 ml/min; p=0.020). Conclusion:
Children with type 1 diabetes mellitus have no more diseased teeth; however,
they have more dental plaque, dental calculus and lower saliva than children
in the control group. Also, our results point to the absence of preventive
measures and programs in Montenegro.

Beberapa tahun terakhir ini, koruptor semakin kreatif dengan melakukan tindak korupsi di negara asalnya dan melarikan diri ke negara lain berikut dengan aset-aset yang telah diambilnya ditanam di negara tempatnya bersembunyi. Kehadiran orang tersebut kenegara lain adalah untuk menghindari upaya penangkapan atas dirinya sehubungan dengan kejahatan yang telah dilakukannya di negara asal. Dengan larinya orang tersebut ke negara lain, ini berarti ada negara lain yang kepentingannya dirugikan karena tidak dapat menangkap orang tersebut, padahal orang tersebut telah melakukan pelanggaran hukum. Komitmen masyarakat internasional untuk menanggulangi kejahatan-kejahatan lintas batas melalui kerjasama internasional dapat terlihat dari instrument-instrumen hukum internasional yang lahir belakangan ini, baik yang bersifat hard law maupun soft law. Salah satunya adanya perjanjian ekstradisi. Pada 27 April 2007, pemerintah Republik Indonesia dengan gagah berani menandatangani perjanjian ekstradisi dan perjanjian kerjasama pertahanan (Defense Cooperation Agreement) dengan Singapura.

Dengan adanya lembaga ekstradisi ini maka pelaku kejahatan yang melarikan diri ke negara lain diharapkan tidak akan lepas dari jangkauan hukum. Dalam penelitian ini yang akan dibahas adalah permasalahan mengenai: Apakah norma-norma yang ada dalam Undang-undang No. 1 Tahun 1979 Tentang Ekstradisi masih relevan dan selaras/harmonis dengan perkembangan hukum ekstradisi internasional dalam hal ini perjanjian ekstradisi antara Indonesia dan Singapura. Penelitian ini dilakukan dengan melakukan pendekatan normatif yang bersifat Library Research (penelitian Kepustakaan) dan deskriptif, penulisan ini menggunakan data sekunder dengan bahan hukum primer berupa peraturan perundang-undangan, bahan hukum sekunder seperti buku-buku maupun karya ilmiah, serta bahan hukum tersier berupa kamus. Analisa dilakukan dengan menggunakan metode analisa data secara kualitatif yang bersifat perspektif analitis.
