Company Analysis – The Beginning Step for Scholarly Research
Authors: Aithal P. S.
Published: November 2020

Company analysis is the important type of case method in Research Methodology and is
commonly used by the beginners of scholarly research. A case study based management research and teaching pedagogy are adopted by many business schools with the belief that it is a most powerful way to study and learn new lessons required to identify, understand, and solve the problems in the process of managing and leading the organizations. Developing a business case on various managing aspects of a company and analysing case forces students to grapple with exactly the kinds of situations, decisions, and dilemmas managers confront every day. Company analysis is a powerful tool in developing both research case study and teaching case study in business management subject. Compared to industry analysis, company analysis gives focused and deeper insight into a company and its business in terms of challenges and opportunities. In this paper, we have discussed the procedure of writing company focussed case study based on a newly developed company analysis framework. We
also recommend the Company analysis as a class of case study methodology in management research for the beginners and budding researchers as a beginning step in scholarly research.
Post-secondary Students’ Perceptions of Career Readiness Skills
Authors: DiBenedetto Catherine A. , Willis Victoria C.
Published: November 2020

Awareness of one’s knowledge, skills, and dispositions are important for college graduates to excel in the workforce. The purpose of this study was to administer a needs assessment to students enrolled in the Agricultural Sciences department at Clemson University to determine areas of discrepancy based on perceived levels of proficiency and importance of knowledge, skills, and dispositions for career readiness. The Borich needs assessment model was used to discern between student’s perceived competency and importance of career readiness skills within nine constructs. Constructs were analyzed and ranked using mean and grand mean weighted discrepancy scores. We found career skills, interdisciplinary skills, life skills, and learning skills ranked as the highest areas of need. Some differences were revealed among the three majors in the department, but career skills were consistently ranked as students’ highest priority need. The majority of the students believed they were most responsible for developing skills to prepare themselves to be career ready. Recommendations included expanded data collection among employers, faculty, secondary education teachers and students, and post-secondary students enrolled at technical colleges and conducting a pre/post survey of students as they enter their first semester and complete their final semester to determine any change in student perception over time.
The Effect of Virtual Reality Technology on Welding Skill Performance
Authors: Wells Trent , Miller Greg
Published: November 2020

Simulator technologies such as virtual reality (VR) can serve as practical tools in the educational process. VR technology applications can be effectively used for weld process training. Weld process training can often be found in university-level agricultural education settings. We sought to determine if using a VR technology application within the context of a one-hour-long gas metal arc welding (GMAW) process training impacted welding skill performance as determined by certified welding inspectors (CWIs) who used a weld evaluation rubric based on American Welding Society (AWS) standards. One-hundred-and-one students from Iowa State University participated in our study. Participants were randomly placed into one of four protocol groups: (1) 100% live welding, (2) 100% VR welding, (3) 50% live welding / 50% VR welding, or (4) 50% VR welding / 50% live welding. A one-way analysis of variance (ANOVA) indicated there were no statistically significant differences (p > .05) in total weld scores between participants in the four training protocol groups. We recommend this study be replicated.

Authors: Bird William A. , Bowling Amanda M. , Ball Anna L.
Published: November 2020

This study’s purpose was to determine the influence of involvement level, autonomy, and reflection during FFA civic engagement activities on students’ self-perceived civic responsibility levels. The study utilized a quasi-experimental, non-equivalent comparison group design. The treatment consisted of two groups: an experimental reflection group and a control group. Four school-based agriculture programs agreed to participate, providing a time and place sample of 282 respondents. Simultaneous multiple linear regression models explained significant variance in students' levels of self-perceived civic responsibility scores using a linear combination of involvement level, autonomy, and structured, guided reflection. Data analysis revealed positive, statistically significant relationships between the autonomy and reflection variables and youths’ perceived levels of civic responsibility. These findings can inform educator practices for designing FFA civic engagement programming
Exploring Motivational Strategies, Outcomes, and Theories within the Career Development Event Preparation Process
Authors: Bowling Amanda M. , Ball Anna L. , Bird William A.
Published: November 2020

Due to the competitive nature of Career Development Events (CDEs), teachers must utilize various instructional and motivational strategies to engage students and encourage student participation. This qualitative intrinsic case study analyzed the motivational practices of a previously successful agriculture education teacher to determine the motivational strategies and the underlining motivational theories utilized during the CDE preparation process. Researchers conducted field observations and interviews during CDE practices. The teacher employed numerous motivational strategies to improve the motivation and preparation of the CDE teams. The teacher’s motivational strategies can be aligned to the theories of self-determination theory (SDT), expectancy-value theory (EVT), goal setting, and mastery goal orientation. Through this analysis, the researchers developed a visual model to align the progress of motivation and preparation, theories, related strategies, and subsequent student outcomes. Teachers should use the findings to reflect on their current CDE motivational practices, determine how their strategies align with the visual model and develop a set of motivational strategies to achieve the desired student outcomes within the CDE preparation process. More research should be conducted to better understand the use of motivational strategies and theories within the CDE preparation process.
Qualitative Analysis of PLP in LSTM for Bangla Speech Recognition
Authors: Al Mahmud Nahyan , Amjad Munni Shahfida
Published: November 2020

The performance of various acoustic feature extraction methods has been compared in this work using Long Short-Term Memory (LSTM) neural network in a Bangla speech recognition system. The acoustic features are a series of vectors that represents the speech signals. They can be classified in either words or sub word units such as phonemes. In this work, at first linear predictive coding (LPC) is used as acoustic vector extraction technique. LPC has been chosen due to its widespread popularity. Then other vector extraction techniques like Mel frequency cepstral coefficients (MFCC) and perceptual linear prediction (PLP) have also been used. These two methods closely resemble the human auditory system. These feature vectors are then trained using the LSTM neural network. Then the obtained models of different phonemes are compared with different statistical tools namely Bhattacharyya Distance and Mahalanobis Distance to investigate the nature of those acoustic features.
Impact of biomass burning aerosols on radiation, clouds, and precipitation over the Amazon: relative importance of aerosol–cloud and aerosol–radiation interactions

Abstract. Biomass burning (BB) aerosols can influence regional and global
climate through interactions with radiation, clouds, and precipitation.
Here, we investigate the impact of BB aerosols on the energy balance and
hydrological cycle over the Amazon Basin during the dry season. We performed simulations with a fully coupled meteorology–chemistry model, the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem), for a range of different BB emission scenarios to explore and characterize nonlinear effects and individual contributions from
aerosol–radiation interactions (ARIs) and aerosol–cloud interactions (ACIs).
The ARIs of BB aerosols tend to suppress low-level liquid clouds by local
warming and increased evaporation and to facilitate the formation of
high-level ice clouds by enhancing updrafts and condensation at high
altitudes. In contrast, the ACIs of BB aerosol particles tend to enhance the
formation and lifetime of low-level liquid clouds by providing more cloud
condensation nuclei (CCN) and to suppress the formation of high-level ice
clouds by reducing updrafts and condensable water vapor at high altitudes
(>8 km). For scenarios representing the lower and upper limits of BB emission
estimates for recent years (2002–2016), we obtained total regional BB
aerosol radiative forcings of −0.2 and 1.5 W m−2,
respectively, showing that the influence of BB aerosols on the regional
energy balance can range from modest cooling to strong warming. We find that
ACIs dominate at low BB emission rates and low aerosol optical depth (AOD),
leading to an increased cloud liquid water path (LWP) and negative radiative
forcing, whereas ARIs dominate at high BB emission rates and high AOD,
leading to a reduction of LWP and positive radiative forcing. In all
scenarios, BB aerosols led to a decrease in the frequency of occurrence and
rate of precipitation, caused primarily by ACI effects at low aerosol
loading and by ARI effects at high aerosol loading. The dependence of
precipitation reduction on BB aerosol loading is greater in a strong
convective regime than under weakly convective conditions. Overall, our results show that ACIs tend to saturate at high aerosol loading,
whereas the strength of ARIs continues to increase and plays a more important
role in highly polluted episodes and regions. This should hold not only for
BB aerosols over the Amazon, but also for other light-absorbing aerosols
such as fossil fuel combustion aerosols in industrialized and densely
populated areas. The importance of ARIs at high aerosol loading highlights
the need for accurately characterizing aerosol optical properties in the
investigation of aerosol effects on clouds, precipitation, and climate.

Published: November 2020

Abstract. We present new estimates of the regional North Atlantic (15° N–80° N) CO2 flux for the 2000–2017 period using atmospheric CO2 measurements from the NOAA long term surface site network in combination with an atmospheric data assimilation system (GEOSChem–LETKF). We also assess the sensitivity of flux estimates to the representation of the prior ocean flux distribution and to the associated specification of prior flux uncertainty, including a specification that is dependent on the agreement among the multiple representations of the prior ocean flux. Long term average flux estimates for the 2000–2017 period are −0.26±0.04 PgC y−1 for the subtropical basin (15° N–50° N), and −0.25±0.04 PgC y−1 for the subpolar region (50° N–80° N, west of 20° E). Our basin–scale estimates of the amplitude of interannual variability (IAV) are 0.037±0.006 PgC y−1 and 0.025±0.009 PgC y−1 for subtropical and subpolar regions respectively. We find a statistically significant trend in carbon uptake for the subtropical North Atlantic of −0.062±0.009 PgC y−1 decade−1 over this period.
The Influence of Dune Aspect Ratio, Beach Width and Storm
Characteristics on Dune Erosion for Managed and Unmanaged
Beaches
Authors: Itzkin Michael , Moore Laura J. , Ruggiero Peter , Hacker Sally D. , Biel Reuben G.
Published: November 2020

Abstract. Dune height is an important predictor of dune impact during a storm event given that taller dunes have a lower likelihood of being overtopped. However, the temporal dominance of the wave collision regime, wherein significant volume loss (erosion) from the dune will occur through dune retreat without the dune being overtopped, suggests that dune width must also be considered when evaluating the vulnerability of dunes to erosion. We use XBeach, a numerical model that simulates hydrodynamic processes, sediment transport, and morphologic change during a storm, to analyze dune erosion as a function of dune aspect ratio (i.e., dune height versus dune width) for storms of varying intensity and duration. We find that low aspect ratio (low and wide) dunes lose less volume than high aspect ratio (tall and narrow) dunes during longer storms, especially if they are fronted by a narrow beach. During more intense storms, low aspect ratio dunes experience greater erosion as they are more easily overtopped than high aspect ratio dunes. In managed scenarios where sand fences are used to construct a fenced dune seaward of the existing natural dune, we find that the fenced dune effectively prevents the natural dune behind it from experiencing any volume loss until the fenced dune is sufficiently eroded, reducing the magnitude of erosion of the natural dune by up to 50 %. We also find that beach width exerts a significant influence on dune erosion; a wide beach offers the greatest protection from erosion in all circumstances regardless of dune morphology or storm characteristics. These findings suggest that efforts to maintain a wide beach may be effective at protecting coastal communities from dune loss. However, in maintaining wide beaches and dunes, the protection offered in the short-term must be considered against long-term detrimental effects of potentially limiting overwash fluxes, which are critical to maintaining island elevation as sea level rises.
Die geographischen Grenzen abstrakter Gleichheit
Authors: Belina Bernd
Published: November 2020

Abstract. Equality, a concept so central to democratic societies, is being scrutinized in a critical manner in this paper. It argues that the spatial borders of territorial states are also the limits of the validity of the principle of abstract equality, of its ideological productivity as well as its emancipatory potential. The paper discusses the Marxist critique of the limitations of the merely abstract, formal understanding of equality that is inscribed into the structures of democratic states, and the ways in which both the Marxist tradition and current theories of radical democracy find an emancipatory potential in the demand for abstract equality that makes possible going beyond its very abstractions. The focus of these discussions is on how spatiality is integrated into theories of radical democracy on the level of theory. The paper suggests that combining the insights on the productivity of spatial forms from discussions in human geography with the critique of merely abstract equality is a decidedly geographical contribution to the development of theories of the political.

Published: November 2020

Abstract. Ground Penetrating Radar (GPR) survey was carried out to estimate the ice thickness and mapping the bedrock topography at Znosko glacier on King George Island, Antarctic Peninsula during 25th Peruvian Antarctic Expedition (2018). GPR surveying did at 5.2 MHz frequency with a 16 m antenna gap (transmitter and receiver). The mean ice thickness profiles vary from 7 to 123 m across the 350 m profile length. This high-resolution survey also identified a different type of ices and glaciological features which will help in modelling the nature of the glaciers in the future.
Impact of water vapor diffusion and latent heat on the effective
thermal conductivity of snow
Authors: Fourteau Kévin , Domine Florent , Hagenmuller Pascal
Published: November 2020

Abstract. Heat transport in snowpacks is generally thought to occur through two independent processes: heat conduction and latent heat transport carried by water vapor. This paper investigates the coupling between both these processes in snow, with an emphasis on the impacts of the kinetics of the sublimation and deposition of water vapor onto ice. In the case where kinetics is fast, latent heat exchanges at ice surfaces modify their temperature, and therefore the thermal gradient within ice crystals and the heat conduction through the entire microstructure. Furthermore, in this case, the effective thermal conductivity of snow can be expressed by a purely conductive term complemented by a term directly proportional to the effective diffusion coefficient of water vapor in snow, which illustrates the inextricable coupling between heat conduction and water vapor transport. Numerical simulations on measured three-dimensional snow microstructures reveal that the effective thermal conductivity of snow can be significantly larger, up to about 50 % for low-density snow, than if water vapor transport is neglected. Comparison of our numerical simulations with literature data suggests that the fast kinetics hypothesis could be a reasonable assumption to model snow physical properties. Lastly, we demonstrate that under the fast kinetics hypothesis the effective diffusion coefficient of water vapor is related to the effective thermal conductivity by a simple linear relationship. Under such condition, the effective diffusion coefficient of water vapor is expected to lie in the narrow 100 % to about 80 % range of the value of the diffusion coefficient of water vapor in air for most seasonal snows. This may greatly facilitate the parameterization of water vapor diffusion of snow in models.
The role of heat-flux–temperature covariance in the evolution of weather systems
Authors: Marcheggiani Andrea , Ambaum Maarten H. P.
Published: November 2020

Abstract. Local diabatic heating and temperature anomaly fields need to be positively correlated for the diabatic heating to maintain a circulation against dissipation. Here we quantify the thermodynamic contribution of local air–sea heat exchange on the evolution of weather systems using an index of the spatial covariance between heat flux at the air–sea interface and air temperature at 850 hPa upstream of the North Atlantic storm track, corresponding with the Gulf Stream extension region. The index is found to be almost exclusively negative, indicating that the air–sea heat fluxes act locally as a sink on potential energy. It features bursts of high activity alternating with longer periods of lower activity. The characteristics of these high-index bursts are elucidated through composite analysis and the mechanisms are investigated in a phase space spanned by two different index components. It is found that the negative peaks in the index correspond with thermodynamic activity triggered by the passage of a weather system over a spatially variable sea-surface temperature field; our results indicate that most of this thermodynamically active heat exchange is realised within the cold sector of the weather systems.

Adotando os pressupostos teórico-metodológicos da Onomástica e vinculado ao Projeto ATEMIG – Atlas Toponímico do Estado de Minas Gerais –, projeto em desenvolvimento, desde 2005, na Faculdade de Letras da Universidade Federal de Minas Gerais (FALE/UFMG), este trabalho tem por objetivo apresentar um estudo toponímico, focalizando os topônimos relativos aos membros de associações religiosas em todo o território mineiro, tais como bispo, cônego, dom, frade, frei, monge, monsenhor, padre e papa. Trazida pelos portugueses para o Brasil, no início do século XVI, a fé cristã ganhou extensão territorial, à medida em que se dava o povoamento das terras recém-descobertas e, nesse contexto, merece destaque, a presença dos membros de diferentes irmandades e associações religiosas. Nessa perspectiva, verificou-se que a importância desses religiosos pode ser percebida na toponímia mineira, tanto diacrônica – a partir da observação dos mapas históricos – quanto sincronicamente, quando se observa a tessitura atual do léxico toponímico do Estado.

Published: November 2020

This study investigates employees’ attitudes towards women managers in different types of organizations in the context of Bangladesh. Two groups of respondents – supervisors of the women managers and other employees who report to the women managers were selected for data collection through a multistage procedure. The study found that employees, on the whole, have an indifferent attitude towards women managers at the workplace. Among different aspects pertinent to women's leadership, the employees demonstrated a favorable attitude about the women managers’ knowledge and skill, while the employees feel that maternity and other feminine issues make women less desirable in the managerial positions. As the differences were investigated among the respondents of different demographic groups, significant differences were found among various groups based on gender, age, and sectors of employment. However, no significant difference was found among the employees based on their reporting relation with (supervisor and sub-ordinate) the women managers.

Published: November 2020

The expanding number of chronic respiratory diseases and the new Covid-19 outbreak create an increasing demand for mechanical ventilation (MV). As MV is no longer limited to intensive care units (ICU) and operating rooms (OR), more clinicians should acquaint themselves with the principles of mechanical ventilation. To fully acknowledge contemporary concepts of MV, it is crucial to understand the elemental physiology and respiratory machine nuances. This paper addresses the latter issues and provides insight into ventilation modes and essential monitoring of MV.

A Comparative Study Evaluating C-Reactive Protein, Sputum Eosinophils and Forced Expiratory Volume in One Second in Obese and Nonobese Asthmatics
Authors: Mahender Harish , Amarnath Raja , Vadivelu Sreenivasan
Published: November 2020

Introduction: Asthma and obesity are considered inflammatory disorders. Inflammatory markers—sputum eosinophils, C-reactive protein (CRP) and the forced expiratory volume in one second (FEV1) were analysed to find their association in obese asthmatics and compared with their asthma control test (ACT) to understand these parameters in this phenotype. Material and methods: After completing the asthma control test (ACT), the CRP, FEV1 and sputum eosinophils of sixty asthmatics were compared to find the association of them in obese and nonobese asthmatics and contrasted with their ACT. The data were analysed using IBM SPSS V20.0, Mann-Whitney U test (non-parametric test), Pearson’s correlation coefficient and Fisher’s exact test. Results: We found significant differences for CRP (P = 0.001) and sputum eosinophils (P = 0.001) between obese and nonobese asthmatics, both higher in obese asthmatics and with a significant association with body mass index (BMI) (P < 0.05). The FEV1 levels were independent of the BMI levels of asthmatics. There was a significant correlation between the CRP and sputum eosin-ophils (0.52, P = 0.001) for all asthmatics. There was no significant correlation between FEV1 and sputum eosinophils (nonobese P = 0.120, obese P = 0.388) and between FEV1 and CRP (obese P = 0.423, nonobese P = 0.358) in both obese and nonobese asthmatics. Obesity had an association (P = 0.001) with ACT scores (≤ 19). Conclusions: Sputum eosinophils and CRP were raised in obese asthmatics and had a positive association with BMI. Obese asthmatics had a poorer subjective asthma control than nonobese asthmatics despite FEV1 being independent of the BMI levels. Measuring the systemic inflammatory markers could help in additional interventions in reducing systemic inflammation and thus possibly facilitating better symptom control.

Objective: The objective of the study was to compare the effects of long-term and short-term embryo culture to assess whether there is a correlation between culture duration and clinical outcomes. Methods: Embryos were divided into two study groups depending on whether their post-warming culture period was long-term (20–24 hours) or short-term (2–4 hours). Embryo morphology was analyzed with a time-lapse monitoring device to estimate the appropriate timing and parameters for evaluating embryos with high implantation potency in both groups. Propensity score matching was performed to adjust the confounding factors across groups. The grades of embryos and blastoceles, morphokinetic parameters, implantation rate, and ongoing pregnancy rate were compared.Results: No significant differences were observed in the implantation rate or ongoing pregnancy rate between the two groups (56.3% vs. 67.9%, p=0.182; 47.3% vs. 53.6%, p=0.513). After warming, there were more expanded and hatching/hatched blastocysts in the long-term culture group than in the short-term culture group, but there was no significant between-group difference in embryo grade. Regarding pregnancy outcomes, the completion of re-expansion was faster in women who became pregnant than in those who did not for both culture durations (long-term: 2.19±0.63 vs. 4.11±0.81 hours, p=0.003; short-term: 1.17±0.29 vs. 1.94±0.76 hours, p=0.018, respectively). Conclusion: The outcomes of short-term culture and long-term culture were not significantly different in vitrified-warmed blastocyst transfer. Regardless of the post-warming culture time, the degree of blastocyst re-expansion 3–4 hours after warming is an important marker for embryo selection.

Published: November 2020

Abstract— The evolution of computational techniques in the field of virtual reality has enabled new ways of discussing and using information technology in educational contexts. Given this scenario, new challenges have emerged and, among them, the need to verify the efficiency of teaching techniques in interactive three-dimensional environments must be highlighted. This work aims to show the comparison between the experimental results of the evaluation of a theoretical evaluation model carried out by human experts and the results of an automated theoretical model of evaluation and sensorimotor skills acquisition in an Interactive Virtual Environment. The experiment involved procedures such as needle positioning, insertion, and withdrawal operations in injections in the gluteal region. Results indicate that the evaluation of sensory-motor skills is feasible in interactive 3-D virtual environments, showing a higher level of agreement with the human evaluation within the stage of discriminatory evaluation, followed by a relative agreement in evaluating processes of skill degrees distributed on the basis of an average point found in the experts’ evaluation and that of an automated method.

Published: November 2020

This paper proposes using a wearable device for visualization and control in association with an Unmaned Aerial Vehicle applied to structural inspection of buildings. More specifically, an AR.Drone is controlled through head positions and gestures performed by an operator wearing a Google Glass, and the images captured by the drone are visualized on Glass’s screen. We discuss the problems that arise when such a solution is developed, along with limitations that come from today's available technology and how to overcome them.

Virtual Reality (VR) is becoming a mature technology field. To understand its origins and foresee strategies, a study on the last decade of papers published in the Brazilians´ most prominent symposium (the SVR – Symposium on Virtual and Augmented Reality) has been carried out. Papers were classified according to subject of study (including application domains, sub-areas and technologies, among others) as well asresearch structure (including authorship counts and geographical distribution, research approaches, among others). The study shows that health related applications have received most of the attention although techniques and tools proposal have raised the most recently which could be related to the lowlevel programming languages and frameworks preferences found to this community. The number of Augmented Reality (AR) papers has grown steadily and a great variety of underlying knowledge fields (such as 3D interaction and real-time simulation) is a persistent aspect of SVR. Data also show that expected shift from VRML to other 3D Web technologies have already happened. Although oversees participation has been not constant, papers published in English has proven stable in SVR editions. Few institutions from Southeast have dominated the research area but another few from Northeast have just surpassed them. Regarding the research, a lack of higher-level maturity research approaches has been noticed. In addition, it was found difficult to assess the relevance of papers to other researches due to poor abstracts and no centralized database of papers. The analysis of 262 papers suggest that (i) by improving the research budget to the area could impact productivity; (ii) a centralized database would facilitate recovering past contributions and; (iii) that enforcing more scientifically rigorous papers with better abstracts and written in English could raise the visibility of Brazilians´ research in VR/AR.
