Inspire Intrapreneurship through Management Support: The New Competitive Edge

In the contemporary business world, innovation is more critical than ever. Unlike before, every organization is aware of the significance of innovation in gaining and sustaining competitive advantage over rivals. However, organizations can be more innovative just by triggering and uplifting the intrapreneurial spirit of the employees with the management support. But currently the policies, structures and systems which are developed by the management of the organization tend to isolate innovative and creative employees by demoralizing them from sharing valuable novel insights. There are certain instances where the management agrees with the new idea but later on they encourage employees to continue their work in the traditional way as they are reluctant to move away from their comfort zones. However, there is scant number of evidences from Sri Lankan context. Therefore, the objective of the study is to assess the impact of management support on intrapreneurship with special reference to apparel industry in Sri Lanka. With a standard questionnaire, responses were obtained from 240 non-executive employees from three leading apparel sector organizations in Sri Lanka. Results of regression analysis proved that managerial support significantly impacts on intrapreneurship and as a percentage it is 53.2%. Even in reality, intrapreneurs cannot recognize, nurture or inspire without the support of the management. Hence, management of the organization needs to create a better atmosphere not just to create intrapreneurs but also to recognize and encourage such intrapreneurial employees at
Learning 2-opt Local Search from Heuristics as Expert Demonstrations

Deep Reinforcement Learning (RL) has achieved high success in solving routing problems. However, state-of-the-art deep RL approaches require a considerable amount of data before they reach reasonable performance. This may be acceptable for small problems, but as instances grow bigger, this fact severely limits the applicability of these methods to many real-world instances. In this work, we study a setting where the agent can access data from previously handcrafted heuristics for the Traveling Salesman Problem. In our setting, the agent has access to demonstrations from 2-opt improvement policies. Our goal is to learn policies that can surpass the quality of the demonstrations while requiring fewer samples than pure RL. In this study, we propose to first learn policies with Imitation Learning (IL), leveraging a small set of demonstration data to accelerate policy learning. Afterward, we combine on policy and value approximation updates to improve performance over the expert's performance. We show that our method learns good policies in a shorter time and using less data than classical policy gradient, which does not incorporate demonstration data into RL. Moreover, in terms of solution quality, it performs similarly to other state-of-the-art deep RL approaches.
Relationships between land use and nitrogen and phosphorus concentrations in Berze river basin

According to the latest HELCOM eutrophication assessment excessive inputs of nitrogen and phosphorus to the riverine and marine environments are one of the main reasons for water quality deterioration in the Baltic Sea. Both nitrogen and phosphorus are natural elements in terrestrial and aquatic ecosystems as essential for the plant growth. There are many factors both natural and anthropogenic that impact the amount of excess nutrients discharged in streams and rivers. This research examines how catchment area characteristics in terms of share of different land uses influence nutrient concentrations in water at a sub-basin level. Using the CORINE Land Cover 2018 data and results of Agricultural Runoff Monitoring Programme, as collected in the fifteen Berze river sub-basins during the time period of 2005-2020, the relationships between land use and concentrations of nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), total nitrogen (TN), orthophosphate-phosphorus (PO4P), and total phosphorus (TP) were assessed. In general, the results suggest that with increasing proportion of agricultural land in the catchment area the mean TN, NO3-N, TP, PO4-P concentrations in water are expected to increase. Contrary to agricultural land with increasing proportion of forest and semi-natural areas, the mean TN, NO3-N, TP, PO4-P concentrations in water decrease. With higher proportion of water bodies in the catchment area, the mean concentrations of NH4-N in water decrease as well. The conclusions of this study can be used to evaluate the current situation in the catchment areas where no water quality sampling and hydrology measurements are carried out, as well as for planning purposes of land use change in a given catchment area, which allows to forecast future changes in water quality.
ROBUST PORTFOLIO SELECTION WITH CLUSTERING BASED ON BUSINESS SECTOR OF STOCKS

In recent years there have been numerous studies on portfolio selection using cluster analysis in conjunction with Markowitz model which used mean vectors and covariance matrix that are estimated from a highly volatile data. This study presents a more robust way of portfolio selection where stocks are grouped into clusters based on business sector of stocks. A representative from each cluster is selected from each cluster using Sharpe ratio to construct a portfolio and then optimized using robust FCMD and S-estimation. Calculation Sharpe ratio showed that this method works efficiently on large number of data while also robust against outlier in comparison to k-mean clustering. Implementation of this method on stocks listed on the Indonesia Stock Exchange, which included in the LQ-45 indexed for the period of August 2017 to July 2018 showed that portfolio performance obtained using clustering base on business sector of stocks combine with robust FMCD estimation is outperformed the other possible combination of the methods.
Performance of different process additives on the properties of mango powder obtained by drum drying

ABSTRACT The use of process additives was evaluated in the drum drying of commercial mango pulp, using corn starch, maltodextrin 10/20 DE, and glyceryl monostearate (GMS). The mass flow rate (MFR) and some powder properties were analyzed: moisture content, vitamin C, total phenolic compounds, carotenoids, β-carotene, glass transition temperature (Tg), hygroscopicity, solubility, color, rheological behavior and color of reconstituted pulp. The pulps presented non-Newtonian and pseudoplastic fluid behavior, while Tg values ranged from 29°C to 38°C. The process performed with 3% corn starch and 0.5% GMS (dry basis) resulted in greater MFR (8.0 ± 0.2 kg/h m2) and vitamin C retention (61.0 ± 0.7%).
Can citizen science increase trust in research? A case study of delineating Polish metropolitan areas

We assess the relationship between citizens’ participation in scientific research and public trust in research results within social sciences. We conduct an online citizen science quasi-experiment concerning the delineation of metropolitan areas of Poland’s two major cities. It consists of two stages. In stage one, participants in one region are exposed to citizen science and directly involved in delineating the boundaries of their local metropolitan area. In stage two, we add another region in which participants are not involved in the research process. In both regions we ask the participants to evaluate the level of their trust in the presented maps of respective metropolitan areas: based on citizen science in one region and historical data regression analysis in the other region. Our contribution to the literature lies in two areas. First, we demonstrate how citizen science can be used in urban studies to delineate boundaries of urban and metropolitan areas exhibiting strong functional connections. Second, we show that the participation of local residents in the research process increases public trust in the study results compared to non-participatory ‘traditional academic’ research. These results confirm that citizen science programs deserve to be strongly supported by European institutions as a possible means to resolving the credibility crisis of science, research and evidence-based policies.
Parametrization of effect of metro wagon basic structure door force model

We live in the age, when the speed and quality are in the front partitions of transport. Time between a presentation of a concept and production of a prototype is still shorter. There is mainly the field of automatization of systems. Purely mechanic systems are used in many branches less and less. This is also the case with the issue of a metro door presented by the authors. Manual opening of a door is not currently used. This manner of door opening has been replaced by pneumatic and electric systems. In the process of door design for the solved metro wagon, a pre-sliding type of a door was designed. In case of a metro vehicle, where opening and closing of the door is relatively often, the door and door mechanisms are significantly loaded. By this reason, extraordinary reliability requirements of their functionality have to be taken into account. These forces represent the effect of the door system on a wagon basic structure. Because this problem is quite large, the authors do not present all details related with the design of the door system, however, in this article, they focus mainly on parametrization of a model, which will serve for calculation of loading forces, methodology of creation of equations for calculation of the loads due to the pressure differences, as well as normative requirements in terms of other loads. In order to speed up the process of further proposals, the authors present the methodology of the process of parametrization for determination of force effects in the important structural unit.

Do I Speak Anxiously? A Correla t ion of Sel f -Eff icacy, Foreign Language Learning Anxiety and Speaking Performance

Background: Self-efficacy and anxiety associated with foreign language learning are now recognized as two critical affective factors in foreign language learning. However, little is known about the relationships between these two affective variables and learners' performance while speaking. As a result, the current research aims to determine: EFL learners' self-efficacy, foreign language learning anxiety (FLLA), speaking performance, and the relationship between speaking performance and self-efficacy, speaking performance and FLLA, and selfefficacy and FLLA. Methodology: This research enlisted the participation of seventy sixth-semester students. Three testing instruments were used: a self-efficacy questionnaire, an FLLA questionnaire, and one speech test to assess students' speaking abilities. Findings: Based on these findings, the null hypothesis (Ho) was rejected while accepting the alternative hypothesis (Ha). As a result, there was a substantial positive association between speaking success and self-efficacy, as well as a negative correlation between speaking performance and FLLA and self-efficacy and FLLA. It means that students with high-level speaking performance will have high-level of self-efficacy. Then, the higher students’ speaking performance is, the lower their FLLA becomes. It is in line with the correlation between students’ selfefficacy and FLLA, that students with high-level of self-efficacy would have low FLLA. Conclusion: According to the findings of this study, self-efficacy and FLLA were both positively and negatively related to speaking performance. When the two affective variables were correlated to see whether they had a meaningful relationship, it was discovered that the relationship was both negative and important.

Primary B19V infection during pregnancy is accompanied by a 30% risk of fetal infection, especially in epidemic conditions. Given the important impact of parvovirus B19 infection on maternal and neonate health, this study assessed parvovirus B19 susceptibility among women of childbearing age in Mashhad, northeast Iran. Materials & Methods: Serum samples were collected from 185 women aged 20-35 years living in Mashhad. Cluster sampling was performed in different health centers located in the city to cover the main city area. A commercial ELISA kit was used to measure IgG antibodies against B19V. This study was performed in accordance with the ethical standards mentioned in the declaration of Helsinki. Informed consent was taken from all participants. A questionnaire was filled by each participant. SPSS software Version 11.5 was used for statistical analyses. Findings: Anti-B19 IgG was observed in about 31% of women. Seroprevalence of antiB19 antibodies among different age groups (with 5-year intervals) was not significantly different (p=.839). Also, there was no significant difference among different city areas of Mashhad in terms of anti-B19 IgG seropositivity (.39, p>.05). Conclusion: The prevalence of parvovirus B19 infection varies in different parts of the world. Comparing to other reports, the present study revealed a rather low immunity against parvovirus B19 among women in Mashhad. These findings highlight the potential risk of B19 infection in non-immune/susceptible mothers, which may lead to sever outcomes, especially during epidemics. Copyright© 2021, TMU Press.

Superheroines and superstereotypes? Queer postfeminism, intersectionality and female superheroes in Supergirl

Since the new millennium, there has been a remarkable increase in audio-visual adaptations of superhero comic books (Garcia-Escriva, 2018). Whereas these adaptations used to include predominantly male superheroes, they have started to feature more female superheroes (Curtis & Cardo, 2018). An increase, however, does not imply diverse and rounded representations, since women in superhero movies tend to be depicted in stereotypical and sexualized ways (Kaplan, Miller & Rauch, 2016). Even though previous research has addressed the genre's politics of gender representation, there is a need for research that looks at televised female superheroes from a queer postfeminist lens. Therefore, this study conducted a textual analysis, informed by queer postfeminism and intersectionality theory, to explore how leading female superheroes in the series Supergirl are represented. We concluded that the superhero series Supergirl subverts hegemonic gendered identities through its depiction of both traditional and queer femininities.

S-triazoles are significant five-membered heterocyclic scaffolds due to their wide range of biological activities. Materials & Methods: A new series of Schiff bases (5a-f) were synthesized by the reaction of 4-amino-S-triazoles (3a-c) with furan and benzaldehyde 4(d-e). Then a novel series of triazole thioglycosides (7a-f) were synthesized by the reaction of Schiff bases (5a-f) and T-O-acetyle-α-D-glucopyranosyle-Br in the presence of potassium carbonate as a weak base in acetone. The structure of the products was confirmed by FT-IR, H-NMR, and C-NMR assays. The antimicrobial properties of the newly synthesized compounds were studied against four bacterial strains, including Bacillus cereus, Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli, and two fungal strains, including Aspergillus niger and Candida albicans. Findings: The synthesized compounds exhibited better antifungal activity than antibacterial activity, espetially 7d. Among all the compounds, the compound 7d was found to have the highest activity against C. albicans with IZ=18±0.7 mm, MIC=250 mg/mL, and
Impact of Conversation MapTM Education Tools Versus Regular Care on Diabetes-Related Knowledge of People With Type 2 Diabetes: A Randomized, Controlled Study

Objective. This study compared the effectiveness of Conversation MapTM (CM) education tools versus regular care of adults with type 2 diabetes. Methods. Participants from Spain and Germany were randomized to either four CM education sessions or regular care. Data were collected at baseline (visit 1), immediately posteducation (visit 2), and 6 months later (visit 3). The primary objective was to compare diabetes knowledge between education groups at visit 3, using the Audit of Diabetes Knowledge (ADKnowl) questionnaire (score range 0–100). Results. Of 681 participants randomized (CM 330, regular care 351), 91.8% completed visit 3. Median ADKnowl scores increased significantly (P < 0.001) in both groups (CM visit 1, 60.3; visit 2, 73.5; and visit 3, 72.5; regular care visit 1, 63.3; visit 2, 73.5; and visit 3, 73.6). At visit 3, scores were not ranked significantly differently between education groups (P = 0.284). In Spain (n = 310), visit 3 scores were ranked higher for CM than for regular care (P < 0.001); in Germany (n = 371), the opposite was true (P < 0.001). Of participants receiving regular care, 78.3% of those in Germany and 13.5% of those in Spain had nonCM structured education between visits 1 and 2. In Spain, CM patients had higher satisfaction with care and goal attainment than regular-care patients at visit 2 (visit 2 P < 0.001, visit 3 P = 0.055). In Germany, CM patients had less emotional distress than regular-care patients (visit 2 P = 0.025, visit 3 P = 0.003). Median A1C decreased similarly in both groups and countries. Conclusion. Diabetes knowledge and clinical outcomes improved in both education groups. At visit 3, diabetes knowledge in the CM group was not ranked higher than in the regular-care group. In Germany, where regular care frequently involves structured education programs, diabetes knowledge was ranked higher with regular care than with CM. In Spain, where no structured national diabetes education and awareness programs are in place, scores were ranked higher with CM than with regular care.
Numerical investigation of temperature increment effect on bubble dynamics in stagnant water and Al2O3 nanofluid column

ABSTRACT Formation, growth, and detachment of injected air bubble from a submerged needle in stagnant liquid at the different temperature of fluid, investigated numerically. Experiments have been done for validation of numerical simulation results. The injection flow rate of air was varied between 600 and 1200 mL/h in experimental study. Bubble formation, growth, and detachment information were obtained using high speed camera and visual photography technique. Young–Laplace equation that was derived from the force balance on the bubble, was utilized in numerical simulation. A novel method was used for solution of Young–Laplace equation. The bubble diameter, instantaneous contact angle, volume, and other characteristics of bubble were studied at different temperature of operating condition. Also, the enhancement of temperature in Al2O3 nanofluid with 0.01% volume concentration (φ = 0.01%) was compared with deionized water results. The results reveal that by increasing the Al2O3 nanofluid and the deionized water temperature, the diameter, volume, and center of gravity of bubble decrease; however, the instantaneous contact angle increases. Meanwhile, the size of bubble at Al2O3 nanofluid is larger than of that in deionized water at same temperature. Also, the bubble aspect ratio is almost senseless to temperature increment in both deionized water and Al2O3 nanofluid. Eventually, the variation of operating temperature and adding of nanoparticle to the deionized water have significant influence on behavior of growing bubble.
