Authors: McArt Ronan , McCauley Veronica , Flynn Paul
Published: September 2022

Abstract:  Social Entrepreneurship has been recognised as a means of improving the welfare and quality of life for marginalised and neglected communities around the world. Social entrepreneurs apply entrepreneurial approaches to identify problems; create solutions and marshal the necessary resources to form social ventures. To meet an increased demand for socially driven entrepreneurs we need to increase the supply of citizens armed with the competencies and desires to address future social issues. Society’s capacity to solve both social and economic problems can be augmented through the implementation of carefully designed, multidisciplinary educational programmes in second level education.

This paper presents the findings of the theoretically informed Design Thinking process, that sought to explore how adolescent learners develop shared meaning through collaborative, social interactions centered around solving localised societal challenges. This pedagogical approach, informed by a social constructionist paradigm, required students to collaborate in teams for the creation of an artefact that addressed the sustainable transport needs of their community. The study employed a mixed methods data collection strategy that included both the student and the teacher voice. Data sources included interviews, questionnaires, lesson evaluations and classroom resources. Results from the Social Entrepreneurship Pilot Programme conducted with a teacher and 20 students in small rural post-primary school revealed that social learning is an effective approach to increasing Social Entrepreneurial Intention, 47% of students would consider starting a social venture with their group. Collaborative approaches to problem solving proved an effective means of enhancing student efficacy, empathy, and engagement. 82% of students reported confidence in solving social problems in groups but students reported a decline Social Entrepreneurial Self-Efficacy – indicating collaborative learning works better to increase Perceived Collective-Efficacy. It is anticipated that the research will be of interest to those involved in the delivery of Social Entrepreneurship education and applied research within this field.
The impact of organizational culture on business innovativeness
Authors: Panagiota Xanthopoulou  , Alexandros Sahinidis
Published: September 2022

Τhe majority of studies in the ‘80s and ‘90s proposed that a strong culture is essential to the success of an organization. However, some researchers have since disputed this claim, arguing that while some strong cultures lead to success, others fail. Examining several examples from the market, over time, the so-called "case for a strong culture" presents significant weaknesses. The present study, based on the Competing Values Model, examines the effects of a culture’s strength on the innovativeness of the organization. A sample of 110 Greek Small and Medium Enterprises (SMEs) was examined, of which a total of 504 people responded to a questionnaire. The participating companies range in size, in terms of the number of their staff, from 20 to 250 members, and come from different market segments. The results showed that organizational culture strength is inversely related to a company’s innovativeness and that strong cultures have a negative impact on a company’s innovativeness. The main objective of this research is to reinforce the existing knowledge in the relationship between culture and innovativeness, especially in the field of small and medium enterprises since the vast majority of studies concern culture comparisons between large companies using mainly small samples. The focus of this research is on the growing importance of culture given the globalization of the market, the increasing pace of mergers, acquisitions, and strategic alliances between companies with different cultures.
Consumer innovativeness: cross-cultural differences and influence on acceptance of Product Service Systems
Authors: Németh Anna
Published: September 2022

Product Service Systems are considered a new, circular business model that could help businesses be sustainable while maintaining economic growth at the same time. Consumer innovativeness can predict and influence acceptance of such novel business models. However, differences in innovativeness can vary across countries and should be considered in research. This study aims to examine differences and influence of consumer innovativeness on consumer acceptance of Product Services Systems based on data collected from Czech Republic, Sweden and Hungary. For the analysis pay-per-wash was chosen, as washing machines are one of the most used everyday products. This paper takes a descriptive and quantitative approach while using regression as a data analysis method.

The findings enrich current scarce knowledge of differences and influence of consumer innovativeness on consumer acceptance of Product Service Systems, especially considering that Central- and Eastern European countries are underrepresented in the literature. For the managerial contribution, the study offers insights for more efficient consumer segmentation and targeting for introduction of pay-per-wash services.

Authors: Elias Rafaela , Reis Luciana , Delfino Thaise , Fernandes June
Published: September 2022

The COVID-19 pandemic significantly influenced the purchasing behavior of consumers, who began to see in the tools available in the virtual environment the necessary allies to satisfy their consumption desires. Given the relevance achieved by the virtual environment, organizations began to explore more intensively the various digital platforms to enhance their reach to their customers. The traditional electronic commerce then evolved into what we call Social Commerce (S-commerce), which allowed a substantial increase in the way of interacting and promoting sales. Despite the limitations and incipient studies on how organizations use their strategies and explore digital media tools to leverage sales, it is perceived as relevant to understand how the process of joining these organizations to digital media and the influence they have passed to exercise in the reformulation of its strategies and business models. Focusing on the Instagram environment, the objective of this research is to characterize the sales strategies used by three female-owned enterprises, through Instagram, during the pandemic by COVID-19. As a methodological research strategy, the study of multiple cases was used. Three Brazilian female-owned enterprise were analyzed, being: a jewelry company, a women's adult footwear company and a beauty salon. The entrepreneurs responsible for the companies were submitted to a semi-structured questionnaire, which was conducted in loco. As a result, it was observed that the most used Instagram tools are feed resources, stories and metrics. On the other hand, the sales strategies most used by entrepreneurs were e-WOM, recommendations and feedbacks and, finally, encouraging user participation. In conclusion, it was noticed that both the entrepreneur and the company that wants to implement sales strategies in digital media, need to understand the functions and objectives of the set of tools made available by Instagram. Once the functionalities present in these resources are understood, entrepreneurs and managers can formulate their strategies in an assertive way, being more efficient in their commercial transactions, since the actions aim to promote involvement with the public that follows the business. Instagram proved to be a tool with great potential for business in the female sector.

Authors: Suman Swadesh , Gaikwad Sanjay Mahadev
Published: September 2022

This work investigates the effect of different parameters of a static wavy flag vortex generator on the heat transfer in a rectangular channel using Computational Fluid Dynamics (CFD) analysis. This work encompasses optimizing several parameters of a flag such as flag height from the surface, position in the channel, number of triangular shapes in a flag, and rectangular surface area of the flag. Post analysis results exhibit encouraging results with average Nusselt number in flag height (FH) optimization exceeding that in no flag condition by 41.84%, 47.79%, 54.68% for Re 8236, 12354, and 18344, respectively whereas further position optimization of FH optimized flag exceeds average Nusselt number in no flag condition by 46.86%, 70.68% and 87.26% for the corresponding Re. With significantly less practical application of flags for heat transfer enhancement in industry, this work aims to establish flags as an effective heat transfer enhancement device and demonstrate that with the right optimized parameters, a significant increase of heat transfer in the channel can be achieved.

Published: September 2022

The research team at ERAU and UTHSCSA analyzed the effects of suborbital flight stressors and various light conditions (red, white, no light) on the Arthrospira platensis (Spirulina), onboard Blue Origin’s New Shepard vehicle. Commercially available cyanobacterium species were cultivated and closely monitored in mother colonies several months before the suborbital flight mission. The aim of this study was to estimate the biomass production and growth as a potential dietary alternative for prospective human spaceflight's life support system. Spirulina samples were flown in a NanoLab with adjacent avionics supporting the light conditions and sensors to monitor the temperature, relative humidity, and accelerations. The various flight parameters measured in the NanoLab were validated with the flight data gathered by Nanoracks, the flight integrator. Thus, we also assessed the effect of microgravity and different light conditions on the gene expression. Our data indicates that the Spirulina samples onboard the rocket had significant (p < 0.01-0.0001) downregulation of majority of the gene expression.
AFIS based Advanced Power Control Scheme for Grid-Connected DFIG-Driven WECS
Authors: Amin Ifte Khairul , Uddin M. Nasir
Published: September 2022

In wind energy conversion system, extraction of optimum power and efficient operation are two major challenges. In grid connected mode, a doubly fed induction generator (DFIG) control unit is designed to operate at optimum speed to deliver maximum output power in the grid while the voltage, frequency and harmonic regulations need to be fulfilled. Vector control associated with proportional-integral (PI) controllers has been widely applied in wind farms for reliable power regulation of DFIG. As DFIG based wind energy conversion system (WECS) experiences strong nonlinearity and uncertainties originated from the aerodynamics of the wind turbine and magnetic saturation of the generator, different adaptive and nonlinear control schemes have been proposed to resolve the problems associated with fixed-gain PI controllers.
Coupled Error Dynamic Formulation for Modal Control of a Two Link Manipulator having Two Revolute Joints
Authors: Mishra Natraj
Published: September 2022

In the present work, reformulation of the dynamics of a planar two-link manipulator has been presented in the form of joint errors and their derivatives. The linear second-order differential equations with time-varying coefficients represent the Coupled Error Dynamics of the system. In these equations, the non-linear centrifugal and Coriolis terms are expressed as linear functions of joint error rates and the non-linear gravity terms as a linear function of joint errors with time-varying coefficients. After inclusion of linearized version of these terms, the concept of modal analysis is used in the design of a control system for the robot. The developed control approach is compared with the commonly used computed-torque control approach, as applied for a high-speed direct-drive two-link manipulator with revolute joints. Thus in the proposed approach for controller design, the system non-linearities are taken as part of the system representation itself instead of disturbances as assumed in existing approaches.
CO2-Foam Monitoring using Resistivity and Pressure Measurements
Authors: Karakas Metin , Aminzadeh Fred , Graue Arne
Published: September 2022

This paper focuses on combining resistivity and pressure measurements to determine the effectiveness of foam as a mobility control method. It presents a theoretical framework to describe the expected resistivity changes during CO2-foam displacements. With this objective, we first provide equations to estimate the resistivity for CO2-foam systems and then utilize two distinct foam models to quantify these effects. Using analytical solutions based on the fractional flow theory, we present resistivity and mobility distributions for ideal and non-ideal reservoir displacement scenarios. Additionally, assuming pressure measurements only, we examine the inter-dependency between various foam parameters. Our results suggest that the combination of pressure and resistivity measurements in time-lapse mode could be deployed as an effective monitoring tool in field applications of the (CO2) foam processes. The proposed method is novel as it could be employed to predict under-performing CO2-foam floods and improve oil recovery and CO2 storage.
Tidal Force Leap May Cause Malignant Impact on Zener Standard Measurement and Even Aircraft Instrumentation System
Authors: Liu Ling-Xiang
Published: September 2022

From 1996 to 1997, the National Metrology Centre of Singapore (NMC) coordinated the 3rd Asia Pacific Metrology Program (APMP) comparison of dc voltage using a Zener traveling standard. The comparison results at 1.018 V showed a zigzag curve among those laboratories that used their Josephson Array Voltage Standards (JAVSs) for this comparison. The amplitude of the zigzag was more than 1 part in 107, much larger than the typical uncertainty of such standards. These results motivated NMC to search for an explanation, which finally led to the development of an approximate mathematical model to describe this phenomenon [1]. During this developing period a surprising phenomenon was observed: Continuously measured dc voltage output with a periodic fluctuation pattern correlated with the times of tide high and tide low [2]. In addition to this, [2] also mentioned another observation that some of measurements carried out exhibit vast errors during spring tide. Through water molecules’ adsorption or desorption on the insulation of a wiring harness forming the voltage divider, which is situated in an air sealed thermostat of a measured Zener cell, the dc voltage output was very strongly disturbed by spring tides.

Published: September 2022

Desde las últimas décadas del siglo xix y durante la primera mitad del siglo siguiente, la feminización del magisterio primario se consolidó como un fenómeno generalizado en varios países de Latinoamérica. Este artículo analiza comparativamente este proceso, identificando los factores materiales y simbólicos que posibilitaron el incremento sostenido de maestras en el ejercicio de la docencia en Argentina, Uruguay, Perú, Ecuador y Chile. Metodológicamente, el trabajo se basa en el análisis de fuentes documentales de diverso tipo, como censos y compilaciones estadísticas, informes ministeriales y memorias de los ministerios de instrucción pública. El estudio comparado de estas fuentes permitió identificar dos principales trayectorias de feminización del magisterio: por un lado, una feminización temprana, relacionada con la expansión de los sistemas nacionales de educación bajo el alero del Estado Docente. Por otro lado, se reconoció un proceso de feminización de desarrollo más tardío, vinculado a sistemas escolares más descentralizados y con una mayor influencia de la Iglesia Católica. Mientras que la primera trayectoria está representada por los casos de Argentina, Uruguay y Chile; la segunda trayectoria comprende las experiencias de los sistemas educativos de Perú y Ecuador.

Decision-making for granting credit to BUMDes XYZ customers, which is still done manually, allows the results of decisions taken to be subjective, resulting in inaccurate decision results. This inaccurate credit decision has the potential to increase the number of bad loans that occur. This article presents a Decision Support System (DSS) model for assessing creditworthiness using the Simple Additive Weighting (SAW) method, with reference to the 5C criteria (Character, Capacity, Capital, Collateral and Condition). The performance accuracy of the SAW method was tested with 30 samples of bad credit data and current loans of customers of a BUMDes in Bali, using the Confusion Matrix technique. The test results show the Precision value of 95.4% and recall of 91.3%. The accuracy value is classified as Excellent Classification based on the ROC (Receiver Operating Characteristic) curve. The final result of the SAW-based SPK model is then implemented in the form of an SPK application for providing credit to BUMDes XYZ customers.

X-ray Diffraction for Detecting Starch Adulteration and Measuring the Crystallinity Indices of the Polymorphic Modifications of Starch

Introduction: Starch is widely used in the food industry and biotechnology, including for manufacturing food packaging materials. Native starches from various sources exist in the form of three polymorphic modifications (A-, B- and C-types) differing in their crystal structure, which has an indirect effect on their physicochemical and technological properties.

Purpose: To properly and efficiently use starch as a raw material for biotechnology, one needs to preliminarily identify its polymorphic modification and crystallinity, as well as detect and discard adulterants or substandard raw materials. X-ray diffraction is suggested to be a rapid and accurate method for solving the outlined problems.

Methods: In this study, properties of commercial starch from various plant sources (corn, rice, wheat, potatoes, peas, and tapioca) were analyzed by X-ray diffraction and scanning electron microscopy.

Results and conclusion: Starch of some brands was shown to be adulterated: the more expensive potato starch was replaced with cheaper corn starch. The crystallinity indices were determined for all the selected samples; the crystal structure of corn starch was found to be most highly ordered. Contrariwise, the C-type pea starch was characterized by the lowest degree of crystal structure ordering. The findings obtained in this study show that it is necessary to preliminarily determine the source of starch in order to identify its polymorphic modification, as well as physical and chemical properties by X-ray diffraction. This information will be demanded for developing the new types of functional foods and reproducing the currently used biotechnologies.

Published: September 2022

The pervasiveness of online mis/disinformation escalated during the COVID-19 pandemic. To address the proliferation of online mis/disinformation, it is critical to build reliability into the tools older adults use to seek health information. On average, older adult populations demonstrate disproportionate susceptibility to false messages spread under the guise of accuracy and were the most engaged with false information about COVID-19 across online platforms when compared to other age-groups. In a design-thinking challenge posed by AARP to graduate students in a Digital Health course at Tufts University School of Medicine, students leveraged existing solutions to design a web browser extension that is responsive to both passive and active health information-seeking methods utilized by older adults in the United States. This paper details the design-thinking process employed, insights gained from primary research, an overview of the prototyped solution, and insights relating to the design of effective health information-seeking platforms for older adults.
Amplitude Matching for Multizone Sound Field Control

Published: September 2022

A multizone sound field control method, called amplitude matching, is proposed. The objective of amplitude matching is to synthesize a desired amplitude (or magnitude) distribution over a target region with multiple loudspeakers, whereas the phase distribution is arbitrary. Most of the current multizone sound field control methods are intended to synthesize a specific sound field including phase or to control acoustic potential energy inside the target region. In amplitude matching, a specific desired amplitude distribution can be set, ignoring sound propagation directions. Although the optimization problem of amplitude matching does not have a closed-form solution, our proposed algorithm based on the alternating direction method of multipliers (ADMM) allows us to accurately and efficiently synthesize the desired amplitude distribution. We also introduce the differential-norm penalty for a time-domain filter design with a small filter length. The experimental results indicated that the proposed method outperforms current multizone sound field control methods in terms of accuracy of the synthesized amplitude distribution. 
Competitive Indoor-Outdoor User Pairing Algorithms and Resource Optimization in DL-NOMA Systems

Published: September 2022

This work proposes two algorithms for maximizing the sum-rate and fairness in downlink non-orthogonal multiple-access (DL-NOMA) systems with indoor-outdoor user pairing. Specifically, one of the proposed algorithms is based on the streamlined simplex method (SSM), while the other utilizes the least and most cost method (LMCM). The fairness rate in both cases is optimized using the max-min approach for the indoor device, which is assumed to have a lower channel gain due to its inherently more challenging environment. Various performance metrics such as the achievable data rate, fairness index, and energy-efficiency are analyzed to evaluate the effectiveness of the proposed algorithms relative to different benchmarks such as the Near-Far pairing (NFP) and the random user-pairing (RUP). The results show that the LMCM algorithm incurs lower complexity and offers better data rate and energy-efficiency when compared to the SSM algorithm, the NFP and RUP methods.
