Aplicación del Teorema de Bayes en la selección de personal para disminuir la deserción laboral
Authors: Terreros Ríos Armando Josué , Vega Villavicencio Augusta Janneth , Pupo Francisco Juan Marco
Published: November 2019

El teorema de Bayes es un método analítico el cual no descarta casos para calcular las probabilidades de ocurrencia de un suceso, utiliza una estadística que se puede retroalimentar continuamente y obtiene mejores resultados conforme incrementen la cantidad de casos a considerar. La deserción laboral por otra parte es un fenómeno natural en las empresas, se presenta en distinta proporción según variables como el género, edad, escolaridad o incluso según el estado de salud de las personas, que incitan a la desvinculación voluntaria unilateral de los dependientes laborales. La gestión del talento humano convencional realiza evaluaciones puntuales en los procesos de selección de personal, para vincular a la empresa a personas con las más altas habilidades y destrezas para ejercer actividades específicas, sin embargo, no es común que se haga uso de la estadística descriptiva para dar soporte a la toma de decisiones en esta etapa. El presente estudio identificó ocho perfiles de desertores laborales según los casos observados en el cantón Machala a través del uso de la estadística descriptiva para la construcción de una red bayesiana; al principio se realizó una investigación exploratoria para reconocer la problemática, posteriormente se fundamentó teóricamente y describieron las variables asociadas a la deserción laboral, luego se aplicó una encuesta a una muestra de 384 personas para levantar información que se procesó a través del rechazo de casos, conteo de frecuencias y cálculo de probabilidades. La situación laboral de Machala comparte algunas características descritas en otros estudios, sin embargo, también existieron anomalías respecto a la deserción según el género y edad de las personas. Se concluye que la red bayesiana de deserción laboral es una herramienta de soporte del proceso de selección de personal la cual orienta a la elección del perfil idóneo como el menos propenso a desertar.
Pancasila Dalam Interaksi Kearifan Lokal Dan Ideologi Transnasional
Authors: Bhagaskoro Pradipto , Utungga Pasopati Rommel , Syarifuddin Syarifuddin
Published: November 2019

Today, 'transnational ideology' is much assumed as a threat for Indonesian local wisdom. Then, how can local wisdom survive amid the spread of transnational ideology? In essence, current recognized Indonesian religions, even coming from outside Nusantara, are well received because of their interaction with local conditions. These religions open, understand, and accommodate local conditions in order to conform to their teachings. The key point of religious life in Indonesia is the spectrum of its understanding with local wisdom. This paper describes the interaction between local wisdom and transnational ideology in Indonesia and how Pancasila should function in this condition. The first part of this paper describes local wisdom as a cultural product and its habitual manifestations. Second, explanations of transnational ideology and its relations to religions in Indonesia. Third, Pancasila is a reflection of local Indonesian wisdom and a path of interaction with any party, including transnational ideologies that are not yet understood. Fourth, conclusion that explains Pancasila as a form of nation-state presence that provides further understanding for local wisdom towards transnational ideology. This condition may happen as long as the spirit of mutual understanding becomes the basis for every interaction that may come.
Multikulturalisme Desa Di Bali Dalam Kontrol Negara: Implementasi Dana Desa bagi Kegiatan Lintas Budaya di Badung dan Buleleng
Authors: Andreas Noak Piers , Putra Erawan I Ketut
Published: November 2019

This study examines the implementation of village funds related to the development of cross-cultural activities in Badung and Buleleng. Whether the pattern is instructive translation of sloganitic deconcentration tasks or participatory institutionalization that sets out the need for cross-cultural issues in the village. The Tamatea Study (2006), Parker (2017), and Gottowick (2010) discuss multiculturalism as the nature of local wisdom which is described as responding to people's daily problems. Another study, Kwon (2018) and Selenica (2018) looked at multiculturalism in the perspective of intercultural conflict. This research takes a different position from previous research by criticizing the construction of state control over multiculturalism that runs at the grassroots. Control construction is seen from the management of village funds for cross-cultural activities that are operationalized through guaranteed equality of ethnic and religious groups. The research paradigm is non-positive with case studies. Data collection methods utilize observation, interviews and documentation. The perspective used is interpretive with the theory of discourse. Research results show that state control is firmly embedded in the development of multiculturalism in villages. The nature of control is meaningfully driven, administrative control of budgeting has the potential to have an inhibiting effect on the development of the potential of the village concerned, including the development of multiculturalism activities in the village. Such as overlapping regulations on financial accountability, lack of socialization of regulations and assume that village human resources have understood every multicultural development program (especially the deconcentration program), injustice attitude views the potential of the village and bias behavior rules that are biased. Various attitudes are often shown by vertical government officials, such as sub-districts, offices (OPD), and ministries, which are counterproductive to oversee the development of the attitude of the development of multiculturalism in the village. Villages are forced to translate multicultural development programs that are trapped in administrative accountability which in reality compartmentalize the potential of the resources within.

The impact of possible changes to nitrogen loss regulations on the financial viability of dairy farms in the Upper Manawatu River catchment
Authors: Parminter Terry G. , Ridsdale Scott D. , Bryant Stefan A. , McNab Ian G. , Proctor Kate A. , Baish Lynette A.
Published: November 2019

The ManawatÅ«-Wanganui Regional Council regional plan (the One Plan) regulates the use of natural resources in the Region and includes a table of nitrogen leaching maxima reflecting the natural capital of soils in the Region and based on OverseerÂ® results from 2007. Dairy farms applying for controlled consents for intensive land-use activities in the Region need to comply with these maxima. However, the maxima in the Table have not been adjusted as new versions of OverseerÂ® have been introduced since the table was produced.This study compares the impact on representative dairy farms of complying with the original figures in the table with results from a revised table that takes into account more recent versions of OverseerÂ®. Cluster analysis was used to select five representative farms in the Tararua District and their farm systems were modified to comply with both the original and the revised table. The current version of OverseerÂ® was used to model the farm outputs based on the original table of leaching maxima. Compared with the baseline farm results, nitrogen losses were reduced by over 50% and milk production by 40%. When the same comparison was undertaken with the table of revised maxima, the nitrogen losses were expected to reduce by almost 40% and milk production by 5%. Applying the original nitrogen leaching maxima to the five representative farms resulted in about two thirds of farms within the catchment being unable to pay the interest on their debts. The revised nitrogen leaching maxima reduced this to <10%.The nitrogen leaching maxima in the One Plan should be revised to: better reflect the changes in the science underpinning current versions of OverseerÂ®; achieve the nitrogen reduction targets in the region; and minimise the impact of the One Plan policies and rules on the financial viability of existing dairy farms.
Inclusion of persistence in the DairyNZ Forage Value Index
Authors: Ludemann Cameron I. , Chapman David F.
Published: November 2019

Inclusion of a persistence trait into the DairyNZ Forage Value Index (FVI) is an important step toward developing a holistic assessment of the relative value to dairy farm businesses of perennial ryegrass (Lolium perenne) cultivars. For the purposes of the FVI, â€˜persistenceâ€™ was defined as the persistence over time of yield differences between diploid and tetraploid functional groups, and implemented (as an interim step) via two measures: a mean persistence scaling factor (Î¼PS) and a relative pasture renewal cost (RRC). The values of Î¼PS and RRC were estimated by analysing four long-term dry matter (DM) production data sets from across New Zealand, then applied to all cultivars in the 2019 FVI lists. Incorporating persistence reduced the difference in overall FVI value between tetraploids and diploids between $117 and $202/ha (depending on diploid heading date, and region), partially re-balancing the sharp rise in tetraploid values and rankings resulting from incorporation of the metabolisable energy (ME) content trait. Implementing persistence in the FVI at the ploidy level is the first step toward inclusion of cultivar-specific persistence information. This next step will require persistence data for cultivars, plus more information on processes and criteria used by farmers when they decide to renew pastures.
Barriers to IPM adoption for insect pests in New Zealand pastures

Published: November 2019

New Zealandâ€™s pastoral sector faces significant challenges to pest management as long-standing insecticides are deregistered. To protect their pastures, farmers need to shift from reactive responses that lead to poor economic outcomes to pre-emptive responses that are viable in the long term. Current management practices (insecticides, endophytes, biological control) for New Zealandâ€™s pasture insect pests were assessed from the perspective of Integrated Pest Management (IPM). Potential impacts from novel control strategies and emerging digital technologies were evaluated to determine how these could improve pest management. Cryptic IPM is present within the New Zealand pastoral sector: that is, farmers practise various elements of IPM but these elements are not integrated into a cohesive system, so farmers often fail to recognise pest impacts until significant economic losses have occurred. We identified important networks by which farmers, industry and researchers communicate and share information, and can develop strategies to raise awareness of IPM. To encourage adoption, farmers need to feel ownership of pasture IPM. Investment in IPM training for farmers through industry extension networks is essential to prepare farmers for the shift away from chemical insecticides to new biologically based control methods. Adoption of IPM will help pastoralists respond to current and new pest challenges.
Animal performance changes over 11 years after implementing a lucerne grazing system on Bog Roy Station
Authors: Moot Derrick J. , Anderson Pete V.A. , Anderson Lisa J. , Anderson David K.
Published: November 2019

In 2008, Bog Roy was run as a typical high-country station with merino ewes and lambs set stocked for long periods of the year, with 60 ha of lucerne grown for hay. Over the next 7 years, the lucerne and ryecorn areas increased by 30 ha per year. Total lamb meat weaned increased from 91 to 130 t in the first three years direct feeding of lucerne commenced, which improved ewe and two-tooth performance at lambing (% and survival). In the second phase, ewe numbers and pre-weaning lamb growth rates increased. Lambs were weaned earlier and ewes returned to higher pasture covers on hills, which improved their condition score and weights at mating and lambing. In 2016, a change from flood to pivot irrigation resulted in a further production increase to 160 t weaned lamb. By 2018, the mixed age ewes had 141% lambing (to tailing), and pre-weaning lamb growth rates of over 270 g/hd/d which allowed weaning after 80 days. The lamb weaned per ewe mated has increased from 25 to 37 kg over the decade despite increased feed demand from 900 more ewes. These animal performance indicators quantify the transformational change achieved through a focus on grazing and increasing the area of lucerne. This was followed by lucerne and red clover based pastures being established under pivots. The ability to record and quantify changes in stock performance has given the farmer confidence to trust and embrace the transformational change.
The influence of spring grazing management on yield and water use of rainfed lucerne
Authors: Sim Richard E. , Moot Derrick J.
Published: November 2019

Flexible spring grazing management can increase the use of lucerne on farms. However, the negative impacts of set stocking on the survival of plants usually preclude its use. In this experiment, crops of â€˜Stamina 5â€™ lucerne at Ashley Dene, Lincoln University were rotationally grazed, semi-set stocked or set stocked from September to December 2011. Dry matter (DM) yield to December was 6.3 t DM/ha, and consistent among crops. However, the larger leaf area of the semi-set- and set-stocked crops intercepted 45% more solar radiation and transpired 25% more water than the rotationally grazed crop. The set-stocked regime had a lower efficiency of resource use. This was probably due to greater respiration and/or partitioning of DM to the root mass. Set-stock regimes required continual initiation of new shoots from basal buds, which remobilised and, therefore depleted, stored assimilates. To minimise this impact, farmers should maintain a canopy cover of 2 to 2.5 t DM/ha (~20 cm tall) on any set-stocked lucerne. This will maximise radiation interception and compensate for reserve losses. In the study year, grazing management did not influence feed supply through the manipulation of water use because soil evaporation losses were inversely related to crop water use. Consequently, total water use was consistent among crops, with higher soil evaporation from frequent rewetting of the soil for rotationally grazed crops. For farmers, these results suggest continuous grazing of lucerne is possible, but it should be managed to maintain full canopy cover and minimise reserve depletion that will reduce DM yields and stand persistence.
Identifying the pasture potential for New Zealand dairy farms
Authors: Neal Mark B. , Woodward Simon J.R. , Dela Rue Brian T.
Published: November 2019

Higher amounts of pasture and crop eaten on farm are associated with higher profit, and it is likely that many dairy farms have an opportunity to improve their financial performance. Regional averages of pasture and crop eaten are readily available but locally relevant estimates of achievable potential pasture and crop eaten are not, so farmers do not know what improvement to pasture and crop eaten and profitability might be possible. The Pasture Potential Tool was developed to provide a locally relevant estimate of that potential. Data on pasture and crop eaten were sourced from DairyNZâ€™s DairyBase farm performance database, and made available using an interactive web-based tool after testing with pilot groups of farmers. The tool defined a farmâ€™s potential pasture and crop eaten in a particular year as the 90th percentile of farms within a defined radius, or the level that is exceeded by only one in ten farmers, with the data being filtered for comparable soil type and elevation, and adjusted for nitrogen fertiliser application. The tool is available on the DairyNZ website, and has been accessed more than 1300 times in the first 5 months since it went live (as of May 2019).

Space Medicine has grown in parallel to Space Exploration since the second half of the 20th century. Surgery and anesthesia procedures with a special focus on acute surgical conditions management have been investigated and/or performed on animal models and astronauts/cosmonauts. Although total anesthesia has been successfully performed on animal models it is considered of high risk for humans and regional anesthesia techniques have been the method of choice so far. The history of surgery and anesthesia in Space has expanded the limits of these fields and is expected to skyrocket their conjugation with modern technology such as 3D printing.

Published: November 2019

The results of field experiments show that acoustic noise can be used to diagnose the technical state of pipeline supports. The accumulating amplitude spectra of acoustic noise recorded on the pipe surface, allows you to determine frequency and shape of flexural standing waves formed in it. A sharp increase of number of such waves in the studied frequency range and the appearance of antinodes at the pipe fixing points indicate a possible instability of the investigated section of the pipeline.
ON THE INFLUENCE OF SEASONAL CHANGES IN THE NEAR SURFACE RESONANT PROPERTIES ON THE SEISMIC SAFETY OF STRUCTURES
Authors: Fedin Konstantin , Kolesnikov Yury , Ngomayezwe Luckymore
Published: November 2019

The results of experiments to assess the possible influence on seismic safety of structures of seasonal changes in the natural frequencies of the underlying soils are given. It is shown that the resonance properties of the surface soil layer during the year can vary more significantly than the properties of the structures built on them. This can lead to the coincidence of natural frequencies of the soil layer and the structures standing on it, which ultimately reduces their seismic safety.

Knowing that addition of inorganic salts, such as potassium iodide (KI), can modulate the photodynamic action of the photosensitizer (PS), we report in this study the antimicrobial effect of eosin (EOS) and rose bengal (RB) combined with KI against Salmonella enterica serovar Typhimurium and Staphylococcus aureus. Additionally, the possible development of bacterial resistance after this combined aPDT protocol was evaluated. The combination of EOS or RB, at all tested concentrations, with KI at 100 mM, was able to efficiently inactivate S. Typhimurium and S. aureus. This combined approach allows a reduction in the PS concentration up to 1000 times, even against one of the most common foodborne pathogenics, S. Typhimurium, a gram-negative bacterium which is not so prone to inactivation with xanthene dyes when used alone. The photoinactivation of S. Typhimurium and S. aureus by both xanthenes with KI did not induce the development of resistance. The low price of the xanthene dyes, the non-toxic nature of KI, and the possibility of reducing the PS concentration show that this technology has potential to be easily transposed to the food industry.

Plants of the genus Wikstroemia have long been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. This study was designed to determine the effect of chamaejasmine, a biflavonoid present in W. dolichantha, on atopic dermatitis (AD)-like skin lesions in a 2,4-dinitrochlorobenzene (DNCB)-induced murine model of AD. Initially, we examined the anti-allergic activities of ten flavonoids from W. dolichantha by measuring β-hexosaminidase release from RBL-2H3 cells. Subsequently, an SKH-1 hairless mouse model of AD was developed based on the topical application of DNCB. Chamaejasmine (0.5%) or pimecrolimus (1%, positive control) were applied to dorsal skins of DNCB-sensitized AD mice for two weeks. Serum IL-4 and IgE levels were determined using enzyme-linked immunosorbent assay kits and transepidermal water loss (TEWL) and skin hydration were measured using a Tewameter TM210 and a SKIN-O-MAT, respectively. Of the ten flavonoids isolated from W. dolichantha, chamaejasmine most potently inhibited DNP-specific IgE-induced degranulation in RBL-2H3 cells. Topical administration of chamaejasmine attenuated the clinical symptoms of DNCB-induced dermatitis (i.e., itching, dryness, erythema, and edema). Histological analyses demonstrated that dermal thickness and mast cell infiltration in dermis were significantly reduced by chamaejasmine. In addition, 0.5% chamaejasmine inhibited DNCB-induced increases in total IL-4 and IgE levels in serum, improved skin barrier function, and increased epidermis moisture. Our findings suggest chamaejasmine might be an effective therapeutic agent for the treatment of atopic diseases.

Steccherinum ochraceum is a white rot basidiomycete with wide ecological amplitude. It occurs in different regions of Russia and throughout the world, occupying different climatic zones. S. ochraceum colonizes stumps, trunks, and branches of various deciduous (seldom coniferous) trees. As a secondary colonizing fungus, S. ochraceum is mainly observed at the late decay stages. Here, we present the de novo assembly and annotation of the genome of S. ochraceum, LE-BIN 3174. This is the 8th published genome of fungus from the residual polyporoid clade and the first from the Steccherinaceae family. The obtained genome provides a first glimpse into the genetic and enzymatic mechanisms governing adaptation of S. ochraceum to an ecological niche of pre-degraded wood. It is proposed that increased number of carbohydrate-active enzymes (CAZymes) belonging to the AA superfamily and decreased number of CAZymes belonging to the GH superfamily reflects substrate preferences of S. ochraceum. This proposition is further substantiated by the results of the biochemical plate tests and exoproteomic study, which demonstrates that S. ochraceum assumes the intermediate position between typical primary colonizing fungi and litter decomposers or humus saprotrophs. Phylogenetic analysis of S. ochraceum laccase and class II peroxidase genes revealed the distinct evolutional origin of these genes in the Steccherinaceae family.

A study was undertaken of the presence of Listeria monocytogenes in 260 samples of poultry meat obtained from retail outlets in northwestern Spain. L. monocytogenes was detected in 20 samples (7.7%). Twenty strains (one strain per positive sample) were characterized. The strains belonged to 10 serotypes: 1/2a (2 strains), 1/2b (2), 1/2c (2), 3a (1), 3b (2), 3c (2), 4a (2), 4b (4), 4c (1), and 4d (2). Cluster analysis (ribotyping; EcoRI) showed a strong genetic relationship between strains isolated from samples coming from different outlets. Ribotyping permitted some isolates of the same serotype to be differentiated, which points to the possible usefulness of this technique in the epidemiological surveillance of L. monocytogenes. All strains formed biofilm on polystyrene, as shown by confocal laser scanning microscopy. The biovolume (between 621.7 ± 36.0 µm3 and 62,984.0 ± 14,888.2 µm3 in the observational field of 14,161 μm2), percentage of surface coverage (from 2.17 ± 0.84% to 94.43 ± 3.97%), roughness (between 0.399 ± 0.052 and 0.830 ± 0.022), and maximum thickness (between 9.00 ± 0.00 µm and 24.00 ± 14.93 µm) of biofilms varied between strains (p < 0.05). These results expand knowledge of the characteristics of L. monocytogenes isolates from poultry.

Yak yogurt is a type of naturally fermented dairy product prepared by herdsmen in the Qinghai-Tibet Plateau, which is rich in microorganisms. In this study, a strain of Lactobacillus plantarum was isolated and identified from yak yogurt in Hongyuan, Sichuan Province and named Lactobacillus plantarum HFY05 (LP-HFY05). LP-HFY05 was compared with a common commercial strain of Lactobacillus delbrueckii subsp. bulgaricus (LDSB). LP-HFY05 showed better anti-artificial gastric acid and bile salt effects than LDSB in in vitro experiments, indicating its potential as a probiotic. In animal experiments, long-term alcohol gavage induced alcoholic liver injury. LP-HFY05 effectively reduced the liver index of mice with liver injury, downregulated the levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglyceride, total cholesterol, blood urea nitrogen, nitric oxide, and MDA and upregulated the levels of albumin, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase in the serum of liver-injured mice. LP-HFY05 also reduced the levels of interleukin (IL)-6, IL-12, tumor necrosis factor-alpha, and interferon-gamma in the serum of liver-injured mice. The pathological observations showed that LP-HFY05 reduced the damage to liver cells caused by alcohol. Quantitative polymerase chain reaction and Western blot assays further showed that LP-HFY05 upregulated neuronal nitric oxide synthase, endothelial nitric oxide synthase, manganese-SOD, cuprozinc-SOD, CAT, and inhibitor of κB-α mRNA and protein expression and downregulated the expression of nuclear factor-κB-p65 and inducible nitric oxide synthase in the livers of liver-injured mice. A fecal analysis revealed that LP-HFY05 regulated the microbial content in the intestinal tract of mice with liver injury, increased the content of beneficial bacteria, including Bacteroides, Bifidobacterium, and Lactobacillus and reduced the content of harmful bacteria, including Firmicutes, Actinobacteria, Proteobacteria, and Enterobacteriaceae, thus, regulating intestinal microorganisms to protect against liver injury. The effect of LP-HFY05 on liver-injured mice was better than that of LDSB, and the effect was similar to that of silymarin. LP-HFY05 is a high-quality microbial strain with a liver protective effect on experimental mice with alcoholic liver injury.

High fluctuation in cyclic variations influences engine combustion negatively, leading to higher fuel consumption, lower performance, and drivability problems. This paper examines the impacts of injection strategies (injection pressure, injection timing and injection duration) on the cyclic variation of gasoline spark ignition (SI) optical engine under clean and fouled injectors. The principal oscillatory modes of the cycle to cycle variation have been identified, and the engine cycles over which these modes may persist are described. Through the wavelet power spectrum, the presence of short, intermediate and long-term periodicities in the pressure signal have been detected. It was noticed that depending on the clean and fouled injector, the long and intermediate-term periodicities may span many cycles, whereas the short-period oscillations tend to appear intermittently. Information of these periodicities could be helpful to promote efficient control strategies for better combustion. The outcomes report that the cyclic variation of the IMEP happens on multiple timescales, and thus, display complex dynamics. As the fouled injector used, mainly intermittent high-frequency fluctuations are recognized.

Current product composition and quality test methods for the paper and pulp industries are rooted in wet-bench chemistry techniques which cannot be used to distinguish between virgin and secondary fibers. We have recently demonstrated the application of an in situ and nondestructive assessment method based on dielectric spectroscopy (DS), which can address this deficiency in the testing of paper. The DS technique, which employs a resonant microwave cavity, could be applicable to quality assurance techniques such as gauge capability studies and real-time statistical process control (SPC), and may have inherent forensic capabilities. In this paper, we show how this DS technique can be used to distinguish between office copier paper products which may contain recycled fibers. We show a reasonable correlation between the dielectric characteristics (e.g., dielectric loss) and the atomistic level chemical changes that result from the paper recycling process.
