Authors: Antunes Júnior José Antônio Valle , Leis Rodrigo Pinto , Palmeiro Maria Isabel Marcantonio
Published: June 2017

O artigo analisa a evolução do Polo de Inovação Tecnológica da Região Norte do Rio Grande do Sul, inserido em Programa da Secretaria de Ciência & Tecnologia do RS. O referencial teórico adotado baseia-se principalmente no conceito de Sistemas Regionais de Inovação. O método utilizado foi o estudo de caso com a incorporação de subunidades de análise. O objetivo do artigo é identificar os fatores facilitadores e limitadores do desenvolvimento do Polo, tendo sido, inicialmente, identificadas três fases distintas ao longo da sua evolução histórica. Os principais aspectos facilitadores para o Polo foram: constituição de uma política na região; visão explícita e clara da atuação; estabelecimento de uma lógica de governança; autonomia dos pesquisadores para o desenvolvimento de projetos; e transferência de conhecimento entre os atores. Já os aspectos limitadores foram: dificuldade de estabelecer confiança entre os atores; dificuldade de acesso a fontes de financiamento; e dificuldades na gestão da oferta de tecnologia.

Authors: Herscovici Alain
Published: June 2017

O objetivo deste trabalho consiste em realizar, a partir do modelo de Rohfls,  uma análise micro e mesoeconômica das redes eletrônicas e da internet. Em função da complexificação dos Sistemas de Informação e Comunicação (SIC) , acrescentarei as  variáveis que correspondem a essas evoluções, e analisarei as novas formas concorrenciais que caracterizam esses mercados. A este respeito, proporei uma tipologia dos diferentes mercados, e mostrarei porque os mercados nos quais se exerce uma concorrência qualitativa são os mais concorrenciais. Em uma primeira parte, apresentarei o modelo de Rohlfs (1974),  mostrarei em que medida   a complexificação do SIC se traduz por novas modalidades de concorrência, e ressaltarei os limites explicativos deste modelo diante dessas evoluções. Numa segunda parte,  acrescentarei uma série de variáveis ao modelo original de Rohlfs, e  construirei assim uma tipologia das diferentes formas de concorrência e das estruturas de mercado.

Objective: It is controversial whether microorganisms play a role in the pathogenesis of large and medium vessel vasculitides (eg, giant cell arteritis [GCA], Takayasu arteritis [TAK] and focal idiopathic aortitis [FIA]). Recent studies have reported the presence of Varicella Zoster Virus (VZV) within formalin-fixed, paraffin-embedded temporal arteries and aortas of about three-quarters or more of patients with these conditions, and in a minority of controls. In a prospective study, we sought to confirm these findings using DNA extracted from vessels that were harvested under surgically aseptic conditions and snap frozen.Methods and Results: DNA samples extracted from 11 surgically sterile temporal arteries and 31 surgically sterile thoracic aortas were used in an attempt to identify the vessel-associated VZV genome. Two different validated PCR methods were used. Thirty-one thoracic aorta aneurysm specimens included biopsies from 8 patients with GCA, 2 from patients with TAK, 6 from patients with FIA, and 15 from patients without vasculitis, who had non-inflammatory aneurysms. Eleven temporal artery biopsies were collected from 5 patients with GCA and 6 controls. The presence of VZV was not identified in either the specimens from patients with large vessel vasculitis or from the controls.Conclusions: Using surgically sterile snap-frozen specimens, we were unable to confirm recent reports of the presence of VZV in either aortas or temporal arteries from patients with large vessel vasculitis or controls.Keywords: Aorta and temporal artery biopsies, Varicella Zoster Virus, Large Vessel Vasculitis
Configural, Metric and Scalar Invariance Measurement of Academic Delay of Gratification Scale
Authors: Chakraborty Rajib
Published: June 2017

The present study measured the partial (configural, metric and scalar) invariance of Academic Delay of Gratification Scale (ADOGS) for college students prepared by Hefer Bembenutty and Stuart Karabenick (1996), with respect to gender. 488 students (277 boys and 211 girls) from engineering, law, pharmacy, and education faculties of Sultan Ul Uloom Education Society, Hyderabad, were samples of the study. Confirmatory Factor Analysis framework was used to test the three invariance, one at a time, using SPSS AMOS Ver.23. This was done by constraining the factor structure, factor loadings and intercepts for the genders boys and girls simultaneously. The SPSS AMOS CFA test provided Chi-square value and degree of freedom for the unconstrained and the constrained structures. By comparing the difference in the Chi-square test p-value for a degree of freedom of the constrained factor structure with the unconstrained structure’s Chi-Square p-value and its degree of freedom using an excel sheet calculator of Chi-square test available on the Internet, the measurement invariance of the instrument was verified. The findings of the study reveal that the scale is configural and metric invariant, as there is no significant difference between constrained and unconstrained structures. However, the scale is not scalar invariant. The educational implications are discussed.

Vehicle to vehicle (V2V) and Vehicle to infrastructure (V2I) or briefly V2X communications are the one of hot topics in automotive industry. Therefore, this situation is providing many advantages of connected vehicles and infrastructures which bring to human life. For instance, vehicles and road infrastructures which shares information with each other, provides a neat flow regulation, more ordered traffic flow and therefore jammed traffic dependent accident’s percentage will be decreased. On the other hand, security is the most important issue for these systems because the operation of V2X networks is completely dependent on uninterrupted and accurate information sharing. In the light of these information, in this paper we review security issues and current solution architectures. We also propose some open problems in this lively field.

This paper deals with the environmental characterization of a large and densely populated area, with a poor reputation for contamination, considering the contribution of environmental features (air, soil, soil hydraulic and groundwater) and the potential effects on human health. The use of Geographic Information System (GIS) has made possible a georeferenced inventory and, by overlaying environmental information, an operational synthesis of comprehensive environmental conditions. The cumulative effects on environmental features were evaluated, taking into account superposition effects, by means of the spatial multicriteria decision analysis (S-MCDA). The application of the S-MCDA for converging the combination of heterogeneous factors, related to soil, land and water, deeply studied by heterogeneous groups of experts, constitutes the novelty of the paper. The results confirmed an overall higher potential of exposure to contaminants in the environment and higher mortality rates in the study area for some tumours, but hospital admissions for tumours were generally similar to the regional trend. Besides, mortality data may be strictly dependent on the poor socioeconomic conditions, quality of therapy and a lack of welfare in the area relative to the rest of Italy. Finally, as regards the possible relationship between presence of contaminants in the environment and health conditions of the population no definite conclusions can be drawn, although the present study encourages the use of the new proposed methods, that increase the possibilities for studying the combined effect of more environmental factors.

Published: June 2017

Flower bud formation and flowering in chrysanthemum occur under short day conditions (SD), but the molecular basis for the switch to reproductive growth is less well understood than in model plants. Here, a spontaneous mutant able to flower under long days is described. In an attempt to reveal the pathway(s) involved in the formation of flower buds under contrasting daylengths, transcriptome sequencing was carried out in plants grown both under SD and under long day conditions (LD). A number of differentially transcribed genes involved in the various known flowering pathways were identified. Both circadian clock genes and CmFTL3 were up-regulated under SD, thereby inducing floral bud formation and flowering. The gibberellin (GA) signalling pathway-related genes GA20ox and GID1 were up-regulated in the mutant under LD, while the catabolic gene GA2ox and GAI was down-regulated, thereby inducing the transcription of CmFTL1, SOC1 and LFY. The GA content of the leaf was higher in the mutant than in the wild type under LD. When treated with GA, the mutant flowered earlier under both SD and LD, but there was no other detectable phenotype difference between the two lines. The indication was that the photoperiod pathway majorly regulates flower bud formation and flowering time in chrysanthemum under SD. GA signalling pathway only plays a subsidiary role for flowering. However, the GA signalling pathway predominated for flowering under LD.

Published: June 2017

p-Hydroxyphenylpyruvate dioxygenase (HPPD) is not only the useful molecular target in treating life-threatening tyrosinemia type I, but also an important target for chemical herbicides. A combined in silico structure-based pharmacophore and molecular docking based virtual screening were performed to identify novel potential HPPD inhibitors. The complex based pharmacophore model (CBP) with 0.721 of ROC used for screening compound showed remarkable ability to retrieve known active ligands from decoy molecule. The ChemDiv database was screened using CBP-Hypo2 as a 3D query, and the best-fit hits subjected to molecular docking with two methods of LibDock and CDOCKER in Accelrys Discovery Studio 2.5(DS 2.5) to discern interactions with key residues at the active site of HPPD. 4 Compounds with top rank in HipHop model and well-known binding model were finally chosen as identification of lead compounds with potentially inhibitory effects on active site of target. The results provided powerful insight to the development of novel HPPD inhibitors herbicides using computational techniques.

This study investigated the presence of human Norovirus (HuNoV) by genotype in 1,486 groundwater samples, collected from 843 groundwater wells suspected of contamination during 2007-2016, in Republic of Korea. We identified and genotyped 186 HuNoV sequences in 178 HuNoV-positive samples using the RIVM-NoroNet norovirus genotyping tool (NGT) and phylogenetic tree analysis based on RIVM-NoroNet reference sequences. HuNoV GII was more prevalent than GI. The major genotypes detected were HuNoV GII.4 (43.0%), GII.22 (15.6%), GI.5 (10.2%) and GI.1 (8.6%); 14 genotypes accounted for < 5.0%. Increasing HuNoV GII.17 has displayed a worldwide trend, including in Europe and Asia since 2010, and it was the dominant HuNoV genotype during 2013-2014 in Korea. However, HuNoV GII.4 was the major genotype detected in groundwater in Korea in 2015-2016, and it is becoming increasingly prevalent similar to HuNoV GII.17.

As organizações de alta confiabilidade são caracterizadas pelo alto nível de complexidade e de exposição contínua a riscos. Sob esse ambiente, observa-se o surgimento de estresse e de conflitos interpessoais que, para adequada gestão, demandam habilidades de comunicação. Esta pesquisa qualitativa, com delineamento documental, tem por objeto de estudo a comunicação documentada nos casos de incidentes e acidentes ocorridos na Aviação Civil, investigados pela Federal Aviation Administration e pelo Centro de Investigação e Prevenção de Acidentes Aeronáuticos. De acordo com dados das agências, deficiências na comunicação respondem por aproximadamente 80% das ocorrências. Contudo, os resultados da pesquisa, confirmam não haver carga horária suficiente de treinamento de habilidades de comunicação para atendimento específico de situações de extremo risco e de contínua pressão. O treinamento é mais focado em habilidades técnicas do que em habilidades sociais.

ABSTRACT

This article aimed to observe the safety protection of public road transportation and some public areas in Yogyakarta and Surakarta. The Road and urban public transport terminals, station, and transshipment centres were mainly established at the meeting points of different traffic lines.  If we compare the terror-threat against infrastructure, building, and vehicles, then we can see that much more terrorist attacks were directed against the vehicles, than against bridges or tunnels. Safety protection on public road transportation and its  public areas is one of the efforts to enforce  right to life and right to sustain life in line with article 28A of Indonesian Constitution of 1945.  This issue is  important to be observed because two cities are prone to be attacked by terrorist and sometimes passengers or visitors are not responsive to disasters as long as they are on public road transportation and public areas.  This article have two important problem to be observed, first problem is  how already passengers  or visitors of public road transportation and its  public areas understand safety procedures of those areas?; second problem is how policy of safety protection need to be enforced on two public road transportation and public areas in order to protect right to life safely of passengers? The normative and empirical legal research is used  to this research by using interviews and field observation. The result of this research concisely state that at this time the bus station and rail  station is still not implemented maximum safety and security procedures to passengers and passengers or visitors do not understand about safety procedures and are not responsive to dangerous circumtances surrounded  them. Maximum safety protection is important to prevent  terrorism  crime, narcoticss crime, and prevent any casualties due disasters. Security officers should check the condition of bags and luggage of passengers or visitors in order to prevent any threats there. Safety briefing is also implemented to keep a passengers concer.

Comparison of Full Wavefield Synthetics with Frequency-Dependent Traveltimes Calculated Using Wavelength-Dependent Velocity Smoothing
Authors: Chen Jianxiong , Zelt Colin A.
Published: June 2017

Ray theory-based traveltime calculation that assumes infinitely high frequency wave propagation is likely to be invalid in the near-surface (upper tens of meters) due to the relatively large seismic wavelength compared with the total travel path lengths and the scale of the near-surface velocity heterogeneities. The wavelength-dependent velocity smoothing (WDVS) algorithm calculates a frequency-dependent, first-arrival traveltime by assuming that using a wavelength-smoothed velocity model and conventional ray theory is equivalent to using the original unsmoothed model and a frequency-dependent calculation. This paper presents comparisons of WDVS-calculated traveltimes with band-limited full wavefield synthetics including the results from 1) different velocity models, 2) different frequency spectra, 3) different values of a free parameter in the WDVS algorithm, and 4) different levels of added noise to the synthetics. The results show that WDVS calculates frequency-dependent traveltimes that are generally consistent with the first arrivals from band-limited full wavefield synthetics. Compared to infinite-frequency traveltimes calculated using conventional ray theory, the WDVS frequency-dependent traveltimes are more consistent with the first arrivals picked from full wavefield synthetics in terms of absolute time and trace-to-trace variation. The results support the use of WDVS as the forward modeling component of a tomographic inversion method, or any seismic method that involves modeling first-arrival traveltimes.
A Finite-Conductivity Horizontal-Well Model for Pressure-Transient Analysis in Multiple-Fractured Horizontal Wells
Authors: Chen Zhiming , Liao Xinwei , Zhao Xiaoliang , Dou Xiangji , Zhu Langtao , Sanbo Lyu
Published: June 2017

In this paper, we propose a new model for pressure-transient analysis in multiple-fractured horizontal wells (MFHWs) with consideration of pressure drop along the wellbore. To make the physical model better understood, the whole formation is divided into three parts: (1) reservoir, (2) fracture, and (3) wellbore. With incorporating frictional and acceleration pressure drops, a mathematical model with a finite-conductivity horizontal well (FCHW) is developed. Newton-Raphson iterations are used to solve the mathematical model and obtain the transient-pressure solutions of the MFHW. Model verification is performed by comparing with the solutions from a numerical software. On the basis of the field cases from the Ordos Basin, performance prediction, sensitivity analysis, type-curve matching, and evaluations of uncertainty parameters are conducted.

Results show that the contribution of wellbore hydraulics to the total pressure drop increases first and then decreases after reaching the peak value. Ignoring wellbore hydraulics would cause erroneous results during the well-performance forecast. In addition, the dimensionless wellbore pressure of the MFHW increases with an increase in Reynolds number (Re); it decreases as the reservoir/wellbore constant (ChD) increases. Furthermore, the impact of pressure drop on the pressure performance of the MFHW becomes more serious with the increasing Re or the decreasing ChD.

Prácticas curriculares para una convivencia y cultura de paz positiva
Authors: Villalba Cano Janner
Published: June 2017

Las prácticas curriculares de la escuela tradicional aún siguen vigentes en el bordaje y manejo de las conductas violentas y los conflictos escolares. La anterior situación contribuye con una cultura de paz negativa, ya que estas solo centran su atención en la violencia directa generada por los estudiantes, buscan reducirla, no tienen en cuenta la violencia estructural o indirecta, que puede estar arraigada en estructuras de desequilibrio de poder institucional, jerárquico, autoritario. De ahí que la violencia estructural se corresponde con las relaciones, que contribuyen con la injusticia social. Así mismo en esta convivencia la paz que se manifiesta es negativa, donde los conflictos no se toleran, en la medida en que estos se consideran un problema, algo difícil de manejar, una alteración de la tranquilidad, siendo la principal vía para el manejo de estos la sancionatoria o punitiva, la cual lejos de mejorar las conductas de violencia o conflictos los incrementa. Visto esto, los conflictos se consideran un problema y no una oportunidad de potenciar la convivencia. Las actitudes que rigen estas prácticas son dominio, sumisión con habilidades, de individualismo y competencia, esto conlleva a que el estudiante se convierta en un receptor pasivo, acrítico de los problemas sociales del contexto particular y global, lo cual no permite formar un ser humano en valores, frente a las problemáticas sociales que afectan la sociedad. Mientras que las practicas curriculares para la convivencia con un enfoque positivo, propician unos valores de solidaridad, respecto por los derechos humanos, democracia real, con plena participación, inclusión y justicia, además de centrar la atención en disminuir la violencia directa, también intervienen la violencia indirecta o estructural, y consideran los conflictos inherentes al desarrollo de toda estructura social, abordándolos en forma positiva.

El hecho de estar en los tres primeros países en el mundo con mayor número de nuevas víctimas anuales, ser el único país de América Latina en donde aún se siembran minas antipersonal (MAP) de manera indiscriminada, donde existen municiones sin explotar (MUSE), y tener un reporte de más de 9.500 víctimas (entre civiles y militares) desde 1990 hasta la fecha, son algunas de las razones que justifican este estudio.
Effect of age and type of reinforcer in the equivalence – equivalence by a partition procedure
Authors: Garcia Andres , Pérez González Fatima , Martín Vera Rocío , Gutiérrez Domínguez Mayte , Gómez Bujedo Jesús , Pérez Fernández Vicente , Benjumea Rodriguez Santiago
Published: June 2017

Equivalence – Equivalence responding (Barnes et al., 1997), based on derived or non-explicitly trained relational responding, supports a behaviour-analytic model of analogical reasoning. Conditional discriminations are the most common procedure used to train its prerequisites. In this exploratory work we test Vaughan’s (1988) simple discrimination procedure instead to derive Eq-Eq responses in children. Two factors were assessed: type of reinforcer used (primary or secondary) and age of participants (9-10 or 12-13 years). The procedure successfully leaded to the derivation of equivalence – equivalence responses, and both factors influenced the results: selecting older children and applying primary reinforcement leaded to faster learning and better results in the equivalence – equivalence test. No interaction between factors was found. This training procedure can provide a new way to investigate the behavioural prerequisites of this important ability

Male position against violence: preliminary reflections.
Authors: Blanca Franco Mary , Cardona Marín Álvaro Diego , Molina Velasquez David
Published: June 2017

This article is the progress of the first phase of research that seeks to identify the male position against domestic violence developed by the Fundación Universitaria Católica del Norte. The results are documentary reports. During the second phase we will do fieldwork with the male perpetrators that are being attended in public institutions related to domestic violence research. The article discusses 2 aspects: the first refers to the masculine identity and the second involves the Latino men’s perspective on violence. While analyzing the primary sources, it is evident that male population has been conceived as a figure of ostentatious power; responsible for making family decisions. Similarly, research conducted with Latino male aggressors, there are some phenomena associated with violence shown in the first review of documents. In short, male Identity is a psychosocial construction that reflects itself on the linkage to familial ties.
Gaining confidence with intervals: practical guidelines, advices and tricks of the trade to face real-life situations.
Authors: Beaulieu-Prévost Dominic
Published: June 2017

Confidence intervals and measures of effect size are gradually becoming the standard way of reporting the results of statistical analyses in research articles, used instead of or in addition to p values. However, this shift in research practices barely affected teaching practices up to now. This paper is the third of a series written to serve as a general reference on the use of confidence intervals in quantitative social sciences. Its purpose is to provide guidelines, advices and useful tricks of the trade that will allow readers (a) to face most of the statistical problems emerging in real-life research settings and (b) to improve their understanding of confidence intervals and answer more efficiently their questions of interest. The first part of the article briefly introduces the basic elements of an approach based on confidence intervals: Calculations, interpretation, and hypothesis testing. The second part is an attempt to present some of the most important (but sometimes neglected) advanced issues concerning confidence intervals: Graphic representations, complex distributions, national surveys, the larger family of interval statistics (e.g., prediction intervals), and the Bayesian approach to probabilities.
The best of both worlds: a joint modeling approach for the assessment of change across repeated measurements
Authors: An Hsieh Chueh , Von Eye Alexander
Published: June 2017

The usefulness of Bayesian methods in estimating complex statistical models is undeniable. From a Bayesian standpoint, this paper aims to demonstrate the capacity of Bayesian methods and propose a comprehensive model combining both a measurement model (e.g., an item response model, IRM) and a structural model (e.g., a latent variable model, LVM). That is, through the incorporation of the probit link and Bayesian estimation, the item response model can be introduced naturally into a latent variable model. The utility of this IRM-LVM comprehensive framework is investigated with a real data example and promising results are obtained, in which the data drawn from part of the British Social Attitudes Panel Survey 1983-1986 reveal the attitude toward abortion of a representative sample of adults aged 18 or older living in Great Britain. The application of IRMs to responses gathered from repeated assessments allows us to take the characteristics of both item responses and measurement error into consideration in the analysis of individual developmental trajectories, and helps resolve some difficult modeling issues commonly encountered in developmental research, such as small sample sizes, multiple discretely scaled items, many repeated assessments, and attrition over time.
Some thoughts on empirical research
Authors: Juárez Fernando
Published: June 2017

There is currently a great interest in empirical research, ie those using subjects or participants, who undergo some kind of observation, assessment or intervention; still, this type of work is, generally, well received by the scientific community, as they show field, or laboratory, data that allow checking the existence of some phenomenon of interest.

The aim of this study was to assess whether the intervention model in organizational climate PMCO, was effective in the Hospital of Yopal, Colombia. The following five phases, proposed by the model, were implemented: 1) problem analysis, 2) awareness, 3) strategies design and planning, at the individual, intergroup, and organizational levels, 4) implementation of the strategy, and 5) process evaluation. A design composed of two groups, experimental and control, was chosen, analyzing whether there was significant differences between the means of the groups; the t test was applied to high risk dimensions in the organizational climate, such as level of work (t = 2.65), organizational communication (t = 4.32), and the management model (t = 7.99), showing all of them a significant difference (p = ,01) between experimental and control group. It is concluded that the implementation of this model improved the organizational climate in the entity.

This research describes the motivational facts in the soccer professional players, as sportment and internal clients of the corporation Boyacá Chicó Soccer Club. Escala de Motivacion Deportiva (EMD), and Cuestionario de Motivación para el Trabajo (CMT) were both applied. Participants were twenty eight soccer players, whose ages were between 17-39. The results found that in EMD, the internal motivation, by stimulation, predominates over the rest subscales, the lack of motivation is not determinant in the sport behavior. The CMT, allowed finding the factors of salary, recognition and requisition, the latter understood as behavior aimed at obtaining desired rewards, yielded high scores, the self-realization and the content of the task scored low.
Los sesgos cognitivos en la toma de decisiones
Authors: Cortada de Kohan Nuria
Published: June 2017

En este trabajo se hace una presentación del Programa de Heurísticos y sesgos que iniciaron Tversky y Kahneman en el año 1970 y que en el 2002 le valió a Daniel Kahneman compartir el Premio Nobel de Economía. Estos autores han demostrado que en las intuiciones de las personas sobre la probabilidad de los hechos se producen muchos sesgos y, en este trabajo, se señalan algunos de ellos y se dan los ejemplos usados para ello, como la falacia de la ley de los pequeños números, el sesgo de conjunción y otros Se señala, además, el complejo problema de la toma de decisiones en los casos de incertidumbre, se presenta la teoría de las expectativas (prospect theory) y el sesgo de sobre confianza en el que actualmente trabaja la autora de este artículo.
Do the organization types of audit firms matter to earnings conservatism? Evidence from China
Authors: Weng Tzu-Ching
Published: June 2017

This study explores whether legal liability of audit firms is associated with client’s earnings conservatism. In China, audit firms are allowed to choose between legal forms of general partnership (GP) and limited liability corporation (LLC). Because partner auditor is personally liable for all partners’ service in general partnership form, that will provide an incentive for audit partners to monitor each other’s audit quality. Conversely, personal assets of individual partner, under LLC, are no longer available to pay a partnership’s liability, thus reducing the incentives for intrafirm monitoring by partners within an audit firm. Using several different methods for identifying earnings conservatism, this study finds that LLC audit firms are associated with reduced conservatism.
First choice or fallback option? The attractiveness of South Africa’s retail industry for Gen Y members
Authors: Heidig Wibke , Dobbelstein Thomas , B. Mason Roger , Jooste Wayne
Published: June 2017

The wholesale and retail industry is the fourth largest contributor to South Africa’s Gross Domestic Product. However, it faces the major challenge of attracting highly skilled and motivated workers. Although South African universities launched programs in retail management, attracting young talents to a career in retailing remains a tough challenge. Drawing on previous findings from the field of graduate decision-making and industry image from other countries, this research examines the perceptions and expectations of Gen Y members with regard to their field of study and their prospective career. A nationwide survey with 1363 South African first year students, in their first week at university, shows significant differences between freshmen enrolled in retail business management and those enrolled in other business majors. While retail students, as compared to other participants, tend to hold stronger positive associations with their field of study and a retail career, majoring in retailing appears to be a fallback option. Over all participants, the analysis reveals that the perception of retailing careers primarily exceeds expectations on attributes that are only of minor importance. When it comes to important career attributes like payment, work-life balance and advancement issues, the retail image lags behind that of other industries. Comparing the field of study with the preferred industry, we identify four different segments of students that qualify to be targeted by companies and universities in different ways.
Engineering patterns of supply chain optimization to manage oscillation effect
Authors: Patmond Mbhele Thokozani
Published: June 2017

The cascading order variability from downstream trumping up the upstream site of the supply chain network indicates the deleterious effect to the performance of the fast moving consumer goods industry. The fundamental likelihood to optimization in this industry requires dexterous flows of quasi-real-time information, as well as reliable product availability. In this context, this study analyzes the challenges of bullwhip effect on the perspective of ingenious optimization strategies, and further contemplates to establish the engineering patterns of interrelationships on the magnitude of pooling the resources to advance supply chain capabilities. The suppression of bullwhip effect on underlying optimization strategies is sought to elevate accelerated responsiveness, improve network demand visibility and reduce volatility in frequencies to inventory replenishment. A rigorous and disciplined quantitative approach afforded the tentatively development of pattern of interrelated supply chain dimensions. The factor analysis method was used on 448 responses and insightful findings were produced from the compelling purposive sampling technique. The findings indicate that the magnitude of better ameliorating bullwhip effect, the value of competitive economic information and strength of selected optimization strategies depend on the model of unified engineering patterns. This paper provides insights to FMCG industry on using innovative strategies and modern technology to enhance supply chain visibility through integrated systems networks.
