Exploring the factor structure of the Passion Scale: Are the dualistic types of passion relevant for workers in the South African context?
Authors: Bester Marais S. , Coetzee Melinde , Van Lill Xander
Published: November 2020

Orientation: It is not clear from research whether the dualistic model holds true across binary ethnic and gender groups in the South African organisational context.Research purpose: The present research aimed to test the validity and reliability of the two-factor Passion Scale and to assess for measurement invariance of the two-factor scale across binary ethnic and gender groups in the South African context.Motivation of the study: The construct of passion helps to better understand some of the psychological attributes that contribute to experiences of either well-being or strain at work and is therefore an important attribute to measure.Research approach, design and method: The study involved a convenience sample (N = 550) of managerial and staff-level South African employees from various industries with a mean age of 34 years (SD = 10.95). Confirmatory factor analysis, exploratory structural equation modelling, t-tests and tests for measurement invariance were performed.Main findings: The results confirmed the validity and measurement invariance of the two-factor structure of the Passion Scale in the South African work context. The observed differences between the ethnic groups and men and women were practically small.Practical/managerial implications: Well-being interventions should consider the use of the Passion Scale as a measure of the psychological attributes that explain differentiating experiences of harmonious and obsessive passion in the workplace.Contribution/value-add: The findings provided encouraging evidence for the relevance and usefulness of the Passion Scale’s dualistic model of passion for people of different binary ethnic and gender groups in South African organisations.

Aproximación a la prueba ilícita en el proceso laboral
Authors: Soto Zevallos María Stephany
Published: November 2020

El presente trabajo tiene por objetivo poner en evidencia la ductibilidad del límite legislativo del poder de fiscalización del empleador. Este es favorecido por el uso de términos abstractos como «razonable y necesario». Dichos términos quedan al arbitrio del empleador para su definición y para justificar la aplicación de medidas de control laboral, como por ejemplo la videovigilancia. La referida ductilidad permite la obtención de evidencia con vulneración del derecho fundamental del trabajador a la protección de datos personales relacionados con su dignidad. Frecuentemente, la evidencia llega a ser relevante —especialmente cuando guarda relación con imposiciones de medidas disciplinarias— y es admitida en el procesal laboral sin ningún filtro adicional. Esto último atenta contra el debido proceso, debido a que permite el ingreso de una prueba ilícita; por consiguiente, se produce una transgresión que también repercute en el uso ineficiente de los recursos disponibles, así como la incorporación de información contaminada al proceso.
La suspensión perfecta en tiempos de COVID-19. ¿Una alternativa o abuso del empleador?
Authors: Torres Cadillo Rosa Isabel
Published: November 2020

La pandemia de la COVID-19 puso al mundo contra la pared. Como consecuencia de esta, la crisis sanitaria obligó a todos los gobernantes a implementar medidas restrictivas, como los confinamientos obligatorios (cuarentena), suspensión de algunos derechos fundamentales, suspensión temporal de varios rubros económicos que dañó gravemente la economía, a tal punto que muchos negocios cerraron y se vieron obligados a despedir trabajadores, entre otras. Ante ello, el Gobierno peruano implementó algunas medidas alternativas para cautelar los derechos laborales, como por ejemplo la suspensión perfecta de labores —que procura mantener el vínculo laboral entre el empleador y el trabajador— o también la reactivación económica por etapas y otros beneficios como Reactiva Perú.

К 85-летию со дня рождения. Экономический кризис в России: причины и пути выхода
Authors: Ярёменко Ю. В.
Published: November 2020

В нижеприводимом докладе обосновываются направления структурной перестройки экономики РФ, предлагавшиеся в исследованиях Института народнохозяйственного прогнозирования РАН для властных органов в период преобразований в 1990-е годы. Предлагаемые меры исходили из учета особенностей структурно-технологической несбалансированности экономики России, требующих направленных действий государства. Реформы в стране проводились по самым общим монетаристским рецептам, которые имеют мало общего с реальной действительностью нашей неравновесной экономики. Неверный выбор курса во многом объясняется ошибочной трактовкой опыта других стран. Либерализацией цен была нарушена та мера продвижения в сторону мировых цен, которая могла быть усвоена нашей экономикой. Новая ценовая политика должна создать возможности восстановить инвестиционный спрос и начать технологическую модернизацию отставших отраслей, наверстывая упущенное время.

Статья представляет не только исторический интерес. Сегодня острая необходимость структурно-технологических преобразований не только сохраняется, но и усугубляется, поскольку упорно сохраняется сырьевая экономика с небольшим довеском в виде ВПК. «Сама задача проведения новой индустриализации страны не ставится… В 12-ти нацпроектах Президента РФ индустриализации не значится, как и необходимого для нее протекционизма». Обсуждение этих задач и сегодня остается актуальным.

Денежно-финансовые ограничения экономического роста в России
Authors: Говтвань О.Дж.
Published: November 2020

Денежно-кредитная и налогово-бюджетная политика, ориентированные на макроэкономическую стабилизацию, с одной стороны, демонстрируют формальные успехи, что подтверждается динамикой показателей инфляции, бюджетного дефицита и государственного долга. С другой стороны, это не приводит к повышению бизнес-активности, экономическому росту и повышению благосостояния населения. В данной статье предпринята попытка анализа причин, по которым стандартные инструменты макроэкономической стабилизации, применяемые в России, не позволяют активизировать финансирование экономического роста: высокий уровень рисков в экономике, искажения в кредитной селекции, недостаток селективных мер в денежной политике. Это неполный перечень, но и его достаточно, чтобы сделать выводы о необходимости создания целого ряда новых институтов и инструментов и корректировки старых, без чего российская макроэкономическая политика не в состоянии справиться с задачей обеспечения экономического роста.

Published: November 2020

Los guajolotes criollos en el medio rural han tenido un papel de suma importancia ya que han aportado a la población humana proteínas de alta calidad biológica (carne y huevo) por lo general en condiciones adversas. La presente investigación tiene como objetivo describir el perfil hematológico del guajolote criollo de traspatio de la región de Tecamachalco, Puebla. Se seleccionaron y adquirieron 23 guajolotes criollos (GC), que se mantuvieron en confinamiento durante un mes alimentándose con maíz molido y alfalfa, similar al lugar de origen. Para el estudio hematológico se tomó una muestra de dos ml de sangre del ala. Se colocó en un tubo vial con anticoagulante EDTA rotulándose para su identificación. Se realizaron las siguientes determinaciones: Hematocrito (método del Micro hematocrito con tubos capilares, centrifugados a 12.000 r.p.m. durante 5 minutos), Hemoglobina (método de Drabkin), Glóbulos blancos (Neubauer) y Formula leucocitaria (recuento diferencial en frotis según Giemsa). Los resultados obtenidos fueron los siguientes: para hematocrito, proteínas plasmáticas, leucocitos totales, linfocitos, heterófilos, eosinòfilos, basófilos y monocitos, 49.39%, 5.56 g/dl, 22.55x 103/ul, 50.48%,35.35%, 11.57%, 1.65% y 5.87%, respectivamente. Los valores de referencia son: 49.39%, 5.56g/dl, 20 x 103/ul, 50%, 43%, 19%, 3% y 9%, por lo que se considera mínima la diferencia entre lo obtenido y los rangos referenciales. Esta información hematológica de los GCM en las condiciones descritas es la base para futuras investigaciones sobre esta especie animal, en particular para los estudios de resistencia a enfermedades y otros factores ambientales.

Se identificó también que las familias que realizan algún proceso de producto alimenticio, en su gran mayoría, es para autoconsumo y/o para venta informal. Las personas que contestaron los cuestionarios en su mayoría son personas de la tercera edad y a los proyectos a los que se les dio más importancia son de carácter ejidal; como la producción del carbón y la goma de mezquite.
ZUM VERHALTNIS VON ATARAXIE UND WAHRHEITSSUCHE BEI SEXTUS EMPIRICUS
Authors: Maslov Denis

This paper concentrates on the relation between two core components in
Sextus Empiricus: tranquility and the search for the truth. Against the view
of M. Gabriel, who denied the consistency of these elements, I argue that
these components can be practiced consistently. I argue that a non-dogmatic concept of investigation could be used by the sceptic to seek the truth
and remain tranquil. Positing something as good and evil by nature is revealed as the proper source of anxiety since it causes an intensive longing
for the item deemed good. The sceptic refuses to hold the truth for the good
through suspension of judgement; as a result, he becomes able to seek the

A Mathematical Model for Randomly-Occurring Low-Rate Denial of Service Attacks
Authors: Chaturvedi Nahush , Mohanty Hrushikesha
Published: November 2020

Low rate attacks, or Denial-of-Service (DoS) attacks of the occasional misbehaviour, can throttle the throughput of robust timed-protocols, like the Transmission Control Protocol(TCP), by creating either periodic or exponentially distributed outages, or transmission disruptions. Such attacks are as effective as full-fledged DoS with high undetectability of the misbehaving network entity. In this paper, we present a mathematical model of Low-Rate. randomly occurring, Denial-of-Service attacks. By viewing the process as a twostate Continuous-Time Markov Chain(CTMC), we have successfully computed the transition and state probabilities of a compromised network entity that can behave normally, while in the normal state. and abnormally, when in the abnormal state.
A Secure Short Signature Scheme Based upon Biometric Security
Authors: Parida Mousumi , Mohanty Sujata
Published: November 2020

This paper presents a short signature scheme whose security is based upon two computationally hard problems, namely, discrete logarithm problem (DLP) and Integer factorization problem (IFP). In this scheme, biometric feature values of the signer are used to compute biometric cryptographic key, which is further used in signature generation. As biometric data is unique to a person, the signature cannot be forged. Also the length of the signature is short, which helps to reduce communication overhead. The verification cost of the proposed scheme is low, thus applicable in real life scenarios, such as e-voting, e-cash and e-commerce.
Coding Schemes for Distributed Storage Systems: Implementation and Improvements
Authors: Tabatabaeian Saman , Lal Rajendra P. , Naik Wilson
Published: November 2020

Distributed data storage systems are used to store data reliably over a distributed collection of storage locations, called peers. Coding schemes are used to store a portion of the data in the peers ensuring the complete retrieval of data, during peer failures. This has applications in various areas like Wireless Networks, Sensor Networks etc. In this framework we consider a large file to be stored in a distributed manner over few peers of limited capacity. Each peer stores a portion of the coded data, without the knowledge of the contents of other peers. Random Coding is one of the coding schemes used for this. In [1] coding coefficients are chosen randomly from a finite field to encode the data. The encoding is basically a linear combination of file pieces (pieces are elements of finite fields). The data downloader downloads these coded data from several peers and decodes to get the original data. The decoding is basically solving a system of linear equations over a finite field, which is the most time consuming step in the whole process. We give a simple C++ implementation of the schemes in [1] and plot the results. We are trying to find a scheme where coding vectors can be chosen such that the decoding complexity is reduced significantly. Also in a dynamic setting where nodes enter and leave system intermittently, are discussed.
A Shared-Disk Database Approach towards Securing Data in the Cloud
Authors: Mishra Debi Prasad , Mishra Ranjita , Tripathy Animesh
Published: November 2020

The increasing popularity of cloud computing in distributed computing environment may have positive as well as negative effects on the data security of service consumers. This paper highlights some major security issues existing in current cloud computing environments. The primary issue to be dealt with when talking about security in a cloud is protection of the data. The idea is to construct a privacy preserving repository where data sharing services can update and control the access and limit the usage of their shared data, instead of submitting data to central authorities, and, hence, the shared-disk database architecture will promote data sharing and privacy of data. This paper aims at simultaneously achieving data confidentiality while still keeping the harmonizing relations intact in the cloud. Our proposed scheme enables the data owner to delegate most of computation intensive tasks to cloud servers without disclosing data contents or user access privilege information.
Goal Programming Approach for Selection of COTS Components in Designing a Fault Tolerant Modular Software System under Consensus Recovery Block Scheme
Authors: Jha P. C. , Bali Vikram
Published: November 2020

The application of computer systems has now crossed many different fields. Systems are becoming more software intensive. The requirements of the customer for a more reliable software led to the fact that software reliability is now an important research area. One method to improve software reliability is by the application of redundancy. A careful use of redundancy may allow the system to tolerate faults generated during software design and coding thus improving software reliability. The fault tolerant software systems are usually developed by integrating COTS (commercial off-the-shelf) software components. This paper is designed to select optimal components for a fault tolerant modular software system so as to maximize the overall reliability of the system with simultaneously minimizing the overall cost. A chance constrained goal programming model has been designed after considering the parameters corresponding to reliability and cost of the components as random variable. The random variable in this case has been considered as value which has known mean and standard deviation. A chance constraint goal programming technique is used to solve the model. The issue of compatibility among different commercial off-the shelf alternatives is also considered in the paper. Numerical illustrations are provided to demonstrate the model.

We explore Chatman’s theory of life in the round, that people living in small worlds will not cross their world’s boundaries to seek information, and examine its application to small populations of China’s ethnic minorities. Method. A qualitative investigation was conducted on information seeking, related to the daily lives of China’s ethnic minorities, and data were collected through in-depth interviews and observations of seventy-eight participants. Analysis. The data were processed by three levels of qualitative data coding. Results. In China, it seems that ethnic minorities with small populations prefer not to cross ethnic borders when seeking information, as they may not want to deviate from their traditions and customs, lifestyles or ethnic identities. Information is sought across borders when the information is general knowledge and important, or in an emergency. Conclusion. It seems that China’s ethnic minorities’ information seeking is consistent with Chatman’s fifth proposition of the theory of life in the round and that this behaviour may be influenced by their traditions and customs, lifestyles and ethnic identities. By applying Chatman’s theory to previously unstudied populations, this research enhances the understanding of ethnic characteristics and traditional culture, as contextual factors that can influence information-seeking behaviour.

What makes a successful business model is a million dollar question. The success or failure of every business depends solely on its business model. Designing a business model is not simply about completing a business plan or determining which products to pursue, it is also about mapping out how one will create on-going value for the customers. It defines where and how the business idea starts, how should it progress, and when it will be successful to create value for the customers? In this era of emerging technologies many start-ups reach to a particular level and fail as they are unable to compete with the current market trends and scenario, but some startups, however, reach to a significant level of success in a very small period of time and then they redefine their strategies of various aspects and then just grow and prosper throughout just through analysing the market and the target customers. The main objective of this paper is to analyse the strategies adopted by three successful companies in designing their business models so that others can take it as a lesson or learning. The paper analysed the business model design strategies of three giant companies which are Paytm, OnePlus and TenCent’s PUBG (player unknown battleground).

Authors: Sethi Amanjeet Singh
Published: November 2020

The existing state of affairs in the hill and rural areas of Uttarakhand is very dangerous as the state has more than fifteen hundred ghost villages and this number is growing day in day out. The villagers from these places are moving out to plain areas within and outside the state mainly for employment opportunities and a variety of other reasons also contributes to this unfortunate process. Comprehending the urgency of the situation several individuals, non-government organizations, self help groups and the different agencies of the government have started a number of initiatives to curb this serious issue of migration. This research article makes an effort to study the circumstances, current scenario and predominant causes in relation to migration for the state of Uttarakhand. The research article mainly focusses on some of the successful cases of social initiatives attempted for helping to create a viable environment so that people do not have to migrate out of their home in search for facilities. The article concludes that such kind of social initiatives have the potential to stop the process of migration and to initiate reverse migration in the state but still a fair distance has to be covered to make this vision palpable.

Published: November 2020

Human senses are natural contributions which transform the information to the brain for further processing to understand what is being presented to an individual through sight, hearing, touch, smell, taste. Senses will also determine the understanding of the different concept being presented and recall those contents or information for the right situation for the right action. To help the individual learner, teachers in various educational institutions should understand and apply the Multi-Sensory Approach in presenting their teaching contents in a classroom teaching to reach out the uniqueness of the individual learner’s learning style and bring the best academic excellence. With the main aim of helping learners with their unique learning style, the “Itagi’s Model of Multi-Sensory Approach” is been developed by Gururaj Itagi. Highlighting various methods, strategies and techniques in teaching process focussing on individual learning style to maximize student’s academic excellence. This model is framed based on the different learning style of students. This framework considers integrated phases of teaching such as auditory, visual and kinaesthetic approach. The model focuses on Adolescence (aged 12-18 years) mainly on students with scholastic backwardness.

A rust fungus, Puccinia paederiae (Dietel) Gorlenko causing galls on the stem of the skunk vine (Paederia linearis Hook. f. var. linealis and P. linealis var. palida (Craib) Puff) was collected for phylogenetic study as no molecular data was exclusively available for this fungus. Three regions of ribosomal DNA sequences, small subunit (SSU), large subunit (LSU) and internal transcribed spacer region 1 (ITS1) were employed. The results of maximum parsimony and Bayesian methods suggested that among the trees with these sequences, this fungus was nested in Pucciniaceae clades and Puccinia species with supportive statistical values. This is the first report on the phylogenetic analysis using multiple genes of the rust, P. paederiae.

Synthetic seed technology is becoming popular due to its wide application in germplasm conservation and for exchanges among countries in the floriculture trade. This method was used to study the bead formations and the conversion capabilities of Cymbidium finlaysonianum Lindl. For artificial seeds, new protocorm-like bodies (PLBs) (about 4 - 5 mm in diameter) of Cymbidium finlaysonianum Lindl. were isolated individually from 2-month-old proliferating PLB-clusters cultured in Vacin and Went (VW) liquid medium supplemented with 8.84 µM 6-benzyl-aminopurine (BAP). Different concentrations of sodium alginate (2, 3, 4 and 5 %) and calcium chloride (CaCl2.2H2O) (75, 85 and 100 mM) were tested to prepare bead formation. The ideal bead was obtained using 3 % sodium alginate and 100 mM CaCl2 for 30 min, resulting in uniform spherical beads. Effects of different media (full-strength MS, ½ MS or ¼ MS liquid medium with 3 % (w/v) sucrose) in gelling matrix on artificial seed germination were explored. Of the various gelling matrices for germination, the ¼ MS liquid medium was the most effective in terms of germination percentage (90 %) and germination date (28 days). Germination of the artificial seeds was observed within 28 - 56 days of formation on various gelling matrices. The effects of different storage conditions and intervals on conversion (into plantlets with shoot and root) ability of artificial seeds were determined. Among the 4 temperature regimes of storage (0 ± 2, 4 ± 2, 8 ± 2 and 25 ± 2 °C), artificial seeds were successfully stored at 8 ± 2 °C, till 105 days showed percentage of conversion frequency at 44.0 % when cultured on a VW medium supplemented with 2 % (w/v) sucrose with 0.2 % (w/v) activated charcoal. The complete plantlets derived from germinated-encapsulated PLBs showed 90 % survival rate during their gradual acclimatization to greenhouse conditions after transferal of rooted plantlets to sterilized coconut husks and irrigation with water twice a day for 3 months under 70 - 80 % relative humidity and about 12 h photoperiod. The highest percentage of plantlet survival recorded at 12 months after reestablishment in the forest was 75.8 %.

An in vitro plant regeneration protocol was successfully established for Cymbidium finlaysonianum Lindl., an epiphytic endangered medicinal orchid, by culturing seeds from 4-month-old green self-pollinated fruits. Tetrazolium (TZ) viability test indicated a mean embryo viability of 97.80 %. Three asymbiotic orchid seed germination media, namely Knudson C medium (KC), New Dogashima medium (ND), and Vacin and Went medium (VW), were studied to select a suitable medium for seed germination. The highest seed germination percentage was 83.8 % on VW medium. Protocorm-like bodies (PLBs) of C. finlaysonianum Lindl. induced from protocorm segments cultured in VW liquid medium supplemented with 8.84 µM 6-benzylaminopurine (BAP) gave the highest % PLB formation and number of PLBs per explant, at 85.7 and 5.2, respectively. VW medium supplemented with 0.2 % (w/v) activated charcoal (AC) gave the highest number of roots per plantlet and root length, at 6.4 roots and 5.2 cm, respectively. The highest percentage of plantlet survival recorded at 24 months after reestablishment in the forest was 71.6 %.

Authors: JIAMJARIYATAM Rossaporn
Published: November 2020

The objective of this research was to study the effect of the ratio between wheat flour (WF) and jackfruit seed starch (JS) on the physical, chemical quality and sensory characteristics of batter coating. The ratio of WF to JS used in the study to make batter coating were 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, 10:90 and 0:100. The WF and JS exhibited the “A-type” crystal form. Increasing JS content in the starch mixture was found to increase amylose content and relative crystallinity significantly. The amount of oil absorption in the battered product decreased significantly with increasing amylose content. The microstructure of the batter coating differed significantly depending on the ratio of WF to JS from 100: 0, 80: 20, 60: 40, 40: 60, 20: 80 and 0: 100. Higher JS content in the batter provided greater homogeneity with a fine starch network and less porosity. In terms of sensory descriptive analysis, adding JS resulted in increased hardness and crispness, but significantly decreased brittleness, puffiness, oiliness and oil coating (p ≤ 0.05). It was found that the highest acceptance levels of batter used the ratio of WF to JS of 50:50 which obtained the highest score in appearance, color, taste, flavor, texture and overall preference.
