THE IMPACT OF ENVIRONMENTAL LIGHT ON GROWTH PERFORMANCE OF JUVENILE CATFISH (SILURUS GLANIS, L., 1758) REARED IN A RECIRCULATING AQUACULTURE SYSTEM

The experiment aimed to determine the impact of environmental light (spectrum, intensity, and photoperiodicity) on the growth performance of juvenile catfish (Silurus glanis, L., 1758), reared in a recirculating industrial aquaculture system (RAS). The experiment was conducted over 60 days and was organized two variants of light intensity, were compared, in replicate, as follows: in first variant (V1) we used green light with an intensity of 80 lx and in the second version (V2) white light with an intensity of 260 lx. The same photoperiodicity regime was applied in both variants 12L:12D. The initial stocking density was 15.66 kg m-3. The indicators of growth performance, obtained at the end of the experimental period, registered the following results: in the experimental variant V1 (white light), the final stocking density was 28.75 kg m-3, SGR 1.44 %/day compared to V2 experimental variant (light green), compared to a final stocking density of 29.99 kg m-3, a value of 1.31% day-1 for SGR were recorded. The final results of the study indicate a higher growth performance for the experimental variant with a green light (V2), a fact which demonstrates that juvenile catfish show technological plasticity concerning light regime.
Cross-Platform News Media Repertoires and Their Political Implications

With the expansion of news media platforms, news media usage patterns and their implications on civic and political engagement have become complex. To better understand these complexities, this study examines cross-platform news media repertoires and their associations with civic and political engagement. By using singlesource data that merged electronic and survey measures of digital and traditional media usage, we investigated the formation of news media repertoires and the influence of news media repertoires on civic and political engagement. We found that South Korean media users form four cross-platform news media repertoires, which significantly differed in age, education, and region. A close examination of news media repertoires revealed that Traditional + Social News Users had higher odds of civic and political engagement compared with News Avoiders. The findings demonstrate how individuals navigate various media platforms and how a combination of such platforms differentially contributes to civic and political engagement.
Microdroplet formation in a t-junction with xanthan gum solutions

The T-junction microchannel device provides a sharp edge to generate microdroplets from polymeric solutions. Different concentrations of xanthan gum solutions were employed as dispersed phase and were compared with Newtonian reference. Canola oil, paraffin oil, and silicone oils (with viscosities varied from 65 to 500 cP) were used for the continuous phase. Experimental results showed that increasing the dispersed phase viscosity resulted in decreasing droplet size for the Newtonian fluids but increasing droplet size for the xanthan gum solutions. Two critical concentrations (0.15% and 0.3%) of xanthan gum solutions were observed resulting in three distinct regimes. The droplet diameter increased with increasing xanthan gum concentration within each regime but transition through each critical concentration was accompanied by a significant reduction in droplet size. For both Newtonian and non-Newtonian dispersed phases, smaller droplets were generated by a higher continuous phase viscosity (muc). A continuous phase with a viscosity around 200 cP was found to result in the minimum drop size distribution. Two critical continuous phase flow rates (2.5 and 7.5 ml/h) were identified that separated the result into three droplet formation regimes - squeezing, transition and dripping. The droplet formation mechanism for each regime is discussed in the paper.
Response of 'Anna' Apple Trees Growth and Yield to Foliar Application Brassinolide, Promalin and Fulvic Acid

This study was carried out during the two successive seasons 2016 and 2017 on eight years old "Anna" apple trees (Malus domestica L.) budded on Balady rootstock, grown in a sandy soil under drip irrigation system in a private orchard located at El-Nubaria, EL-Beheira Governorate, Egypt. The aim of this research was to investigate the response of 'Anna' apple trees growth and yield to foliar application with Brassinolide, Promalin and Fulvic acid. The experimental design was randomized complete block design with four replicates. Results indicated that all foliar application treatments, significantly (P≤0.05) increased vegetative growth characters, fruit set (%) and number fruits per tree as compared with the control during both seasons. Also, all treatments, significantly (P≤0.05) increased fruit weight, yield (kg/tree) and total yield (ton/feddan) as compared with the control treatment, except Promalin treatments during both seasons. It was evident that the application of Brassinolide 0.06 gm/l treatment or Fulvic acid 3 g/l application treatment caused a higher significant increase in yield (18.33 and 18.63 ton/feddan), (18.07 and 18.24 ton/feddan), each in turn, as compared with the control (13.25 and 13.50 ton/feddan) during both 2016 and 2017 seasons. Moreover, all Fulvic acid and Brassinolide application treatments, significantly (P≤0.05) increased fruit size, fruit length, diameter, firmness, total soluble solids (%), total sugars but decrease fruit juice acidity (%) as compared with the control, while no significant differences were recorded between Promalin treatments and control treatment during both seasons. On the other hand, all treatments, significantly (P≤0.05) increased anthocyanin and vitamin C as compared with the control, except Promalin 0.3 g/l and Fulvic acid 1 g/l treatments during both 2016 and 2017 seasons.
Teachers’ Teaching Habits and Academic Achievements of Geography Students in Senior Secondary Schools in Uyo Local Government Area of Akwa Ibom State, Nigeria

The focus of the study was on teacher’s teaching habits and academic achievement of geography students in senior secondary schools in Uyo Local Government Area of Akwa Ibom State. Variables namely teacher’s communication effectiveness and teacher’s classroom management strategies, were examined to see how they differ in academic achievement of students in Geography. To guide the study, two specific objectives, two research questions and two research hypotheses were formulated. Ex-post facto research design was used. The population of the study consisted of all the 2,043 senior secondary two (SS-II) Geography students in public secondary schools in Uyo Local Government Area of Akwa Ibom State. Stratified random sampling technique was used to sample 50% of schools per location while proportional sampling technique was used to obtain a sample size of 201 Geography students for the study. Two instruments namely, Teachers’ Teaching Habits Questionnaire (TTHQ) and Geography Academic Achievement Test (GAAT) were used to collect the data. The instruments were duly validated while their reliability was tested using Cronbach’s Alpha formula 21 of internal consistency. Mean and t-test statistic were used to analyze the data and test the hypotheses at p<. 50 significant level and 199 degree of freedom. The findings of the study showed that there were significant differences in students’ academic achievement in Geography based on the examined independent sub-variables. It was, therefore, concluded that teachers’ teaching habits do enhance students’ academic achievement in Geography. The work recommended, inter alia, that teachers should communicate effectively with their students and that classroom management should not be considered in isolation but from a systems analysis framework.
Environmental training and individual skills for environmental sustainability: a study of three Brazilian chemical companies

This paper aims to analyze how the environmental training process can contribute to the development of individual competencies associated with the environmental dimension of sustainability in large companies in the Brazilian chemical sector. The need to fill theoretical and methodological gaps on the role of the environmental training process, targeted at the environmental dimension of sustainability in the context of companies in the Brazilian chemical sector justifies this study. A qualitative research approach with multiple case studies based on triangulation of evidence sources addressed the theme. The results confirmed that the systematization of the environmental training process can potentiate the development of individual competencies, essential to the sustainability of the companies of the Brazilian chemical sector, considering that the environmental training process is directed at stimulating and developing the competencies aligned with the organizational strategy, based on identified competence gaps.
Salmacis sphaeroides-White Sea Urchin

Cute and cuddly are words people happily associate with furry mammals, particularly if they were recently born. But isn’t the sea urchin in the picture above at least fairly adorable? Most people associate sea urchins either with venomous spines or their edible gonads ( in Japanese), but I like to think uni Salma with its awkward dome shape and a penchant for dressing itself up, is very cute indeed. cis sphaeroides, And yes it can be cuddled, as long as you take care to not damage its spines, which are incapable of drawing blood (unless you throw it at someone, and with quite a bit of force too).
The Impact of Organizational Culture on the Sustainable Competitive Advantage of Commercial Banks: A Case Study in Vietnam

A bank’s competitive advantage helps in enhancing its ability to maintain a competitive advantage in product consumption, expand the consumption market, and effectively use business factors to maximize economic growth. The research aims to investigate the impact of organizational culture on the sustainable competitive advantage of commercial banks in Vietnam. The study adopts a quantitative research method, through structural equation modeling analysis (SEM). A survey was conducted on 608 participants who are staff at commercial banks in Vietnam. Research results show that organizational culture has both a direct and indirect impact on sustainable competitive advantage through factors of social responsibility and knowledge sharing. Based on these findings, the study gives some recommendations to contribute to the creation, maintenance, and development of sustainable competitive advantages of commercial banks. The findings of this study have shown the importance and impact of organizational culture on many aspects of a bank’s sustainable competitive advantage. These are meaningful contributions in both theory and practice to help banks gain more insight into human resources management. The study also raises an issue on the need to care about and develop an organizational culture to bring professionalism, initiative, and fairness in all activities of commercial banks.
The relationship between emotional competence, classroom climate and school achievement in high school students

The aim of this study is, on the one hand, to find out if differences exist in emotional competence and secondary school students’ perceptions of classroom climate according to gender and educational level and, on the other hand, to analyse the relationship between emotional competence, classroom climate and school achievement in secondary school students. The study advances the hypothesis that emotional competences and classroom climate are mediators in school achievement. For this purpose, 420 students from secondary and further education were selected with an average age of 14.29 ± 1.52. In emotional competence, the results showed differences according to gender and educational level, while in classroom climate, differences were only found according to educational level. The mediational analysis showed that classroom climate is an influential variable in the predictive value of emotional competence in relation to school achievement. Likewise, emotional competence acts as a mediating influence on classroom climate and school achievement. This study thus highlights the need to implement training processes to help teachers to promote positive socio-emotional contexts and programmes to develop students’ emotional competence, which will improve their school achievement.
Knowledge level of Rural Women Regarding Home Science Technologies

Women play a key role in food production and form a large proportion of the agricultural work force globally. Knowledge empowerment is crucial in women development. Rural women can create wonders in their society with knowledge gain about different Home Science Technologies. A study was conducted in three randomly selected districts of Andhra Pradesh with sample size of 270 Krishi Vigyan Kendra trained respondents with an objective to measure the knowledge level of rural women regarding Home Science Technologies. Knowledge level was measured in seven different areas – Value addition to millets, nutrition garden, fruit and vegetable preservation, tailoring and embroidery, seed bag technology, vermicompost technology and backyard poultry. The study revealed that average knowledge scores obtained by respondents were medium. The knowledge scores in the areas of fruit and vegetable preservation, value addition to millets. nutrition garden, tailoring and embroidery, vermicompost technology and backyard poultry were in an ascending order. Knowledge scores were significantly related with age, social capital, information source utilisation, innovativeness, value orientation, perception about dissemination method, input availability, market facility and institutional support. The degree of contribution and influence exerted by the different precursor variables than studied variables was observed. Further studies to explore other correlated factors are needed.
The canine adenovirus type 2 (CAdV-2) in Italian wolves: a preliminary study

The canine adenovirus type 2 (CAdV-2) is associated with the infectious tracheobronchitis com- monly called “kennel cough”, cosmopolitan in dogs but little explored in gray wolves. Our goals were (i) to evaluate the presence and circulation of CAdV-2 in free-ranging Italian wolves ( Canis lupus italicus ), through the analysis of spleens and tongues collected from 56 carcasses sampled in three Italian regions between August 2017 and July 2020, and (ii) to support the validity of a matrix such as the tongue, which was never used before. Samples were screened for the presence of CAdV-2 DNA using both PCR and real-time PCR assay. Positive results were related to sampling year, location, sex, age, genetic determination of species, and matrices tested. Three male wolves (5.4%) tested positive in tongue samples, demonstrating that the tongue is an excellent matrix for the detection of CAdV-2. To the best of our knowledge, no studies were performed to evaluate the usability of tongue samples to detect CAdV-2 DNA in grey wolves or other wild animals. The number of wolves tested positive suggests that, during the studied years, the circulation of CAdV-2 in Italian wolves showed a low frequency, consistent with irregular introductions of the virus by dogs or other wild carnivores in these populations. This preliminary study provides new data on the eco- logy of CAdV-2 in Italian wolves, although future studies are needed to fully understand its real circulation at a national scale, its pathogenetic role in gray wolves, and its risk of transmission to other wild carnivores.
Material computation—4D timber construction: Towards building-scale hygroscopic actuated, self-constructing timber surfaces

The implementation of active and responsive materials in architecture and construction allows for the replacement of digitally controlled mechanisms with material-based systems that can be designed and programmed with the capacity to compute and execute a behavioral response. The programming of such systems with increasingly specific response requires a material-driven computational design and fabrication strategy. This research presents techniques and technologies for significantly upscaling hygroscopically actuated timber-based systems for use as self-constructing building surfaces. The timber’s integrated hygroscopic characteristics combined with computational design techniques and existing digital fabrication methods allow for a designed processing and reassembly of discrete wood elements into large-scale multi element bilayer surfaces. This material assembly methodology enables the design and control of the encoded direction and magnitude of humidity-actuated responsive curvature at an expanded scale. Design, simulation, and material assembly tests are presented together with formal and functional configurations that incorporate self-constructing and self-rigidizing surface strategies. The presented research and prototypes initiate a shift toward a large-scale, self-construction methodology.
Skill-Biased Technical Change and Employment in U.S. Manufacturing∗

I propose a new method to decompose employment changes by skill type into changes caused by output, labor supply, production task concentration, and laboraugmenting technology, using market equilibrium conditions within a constant elasticity of substitution production framework. I apply this method to manufacturing industries between 1990 and 2007, a period of steep employment declines for noncollege workers. I find that labor-augmenting technology, by reducing labor per unit of output, is the leading source of displacement overall. However, a shift toward highskill tasks is even more important in displacing non-college workers, who represent a majority of employment. In contrast, output changes have little influence on upskilling or aggregate job loss. In applications, I explore the impacts of import penetration from China and susceptibility to automation and offshoring. Of these, only offshoring is associated with some task upgrading, suggesting these mechanisms are not the primary drivers of employment loss. Finally, I assess the ability of local labor markets to absorb job losses predicted by each channel, and provide evidence that task shocks lead to higher unemployment and labor force non-participation relative to displacement by output decreases or labor-augmenting technology. ∗I am immensely grateful to my dissertation committee Timothy N. Bond, Kevin Mumford, Jack Barron, and David Hummels for their continued advice and support.

Transmission Line Reliability: Climate Change and Extreme Weather

Transmission lines in service today in the US have been designed using a multitude of design approaches and structural loading criteria. The principal cause of structural failures is associated with weather events that produce loads that exceed the structural loading design criteria. In some cases, failures have been the result of inadequate design, construction and/or maintenance practices, airplane or vehicle accidents and criminal activities. The cost of storm-caused transmission outages is significant, costing utilities and users on the order of $270 million per year and $2.5 billion per year (2003 $'s) respectively. The cost of storm damages may be under-appreciated by utilities and regulators since standard industry reliability indices (SAIDI & SAIFI) omit the costs of large storm related outages. Currently available data suggest that the frequency and severity of hurricanes and ice storms will increase in the future. There has been a doubling of Category 4 and 5 Atlantic hurricanes from 1970 to 2004 which is the same time period during which ocean temperatures have increased. If this trend continues, it will have a significant impact on utility and user costs due to structural failures. Studies have shown that increases in CO 2 levels in the atmosphere could increase hurricane wind velocities by about 10%, resulting in an increase in wind loading of about 20%. Under current policy, there is a lack of financial incentives for transmission line owners to upgrade/uprate, refurbish and/or build new lines. For example transmission line owners in restricted jurisdictions do not incur penalties associated with user costs caused by storm outages.
The components and determinants of FDI within firms: A case study of Zambia

This study investigates the response of the components of FDI flows to macroeconomic variables within firms. The analysis uses a new firm-level database constructed from anonymised confidential data held by the Zambian Central Bank, covering the period 2008 – 2017. Applying the fixed effects estimation method, the study confirms a positive association between FDI inflows and commodity prices. The study also confirms a positive correlation between reinvested earnings and exchange rate depreciation. Furthermore, the study accepts, but with a qualification, the preference for intra-company debt financing when there is policy uncertainty in a host country. However, the proposition of a positive relationship between equity financing and currency appreciation in the host country is rejected. The study proposes instead a new hypothesis, a negative relationship between equity financing and the exchange rate appreciation.
Validating DSGE models with VARs and Large-Dimensional Dynamic Factor Models

A popular validation procedure for DSGE models consists in comparing the structural shocks and impulse-response functions obtained by estimation-calibration of the DSGE with those obtained in a SVAR identified by means of some of the DSGE restrictions. The variables included in the VAR are all or part of the variables in the DSGE, usually augmented with measurement errors. The paper argues that this practice can be seriously misleading. For generic values of the parameters of the DSGE, the shocks estimated in the VAR are not “made of” the corresponding structural shocks plus measurement error. Rather, each of the VAR shocks is contaminated by non-corresponding structural shocks. We argue that Large-Dimensional Dynamic Factor Models are free from this drawback and are the natural model to use in validation procedures for DSGEs. JEL classification: C32, C55, E32.
The power of grit on lecturer’s job satisfaction through affective commitment

This study explores the empirical effect of grit on job satisfaction mediating by affective commitment. This research uses a quantitative approach to the survey method through a Likert scale model questionnaire. The research participants are 230 lecturers in Indonesia selected by accidental sampling. Data analysis uses path analysis supported by descriptive statistics and correlational matrics. The research result indicates that grit significantly affects job satisfaction, directly and indirectly, mediating by affective commitment. Thus, the lecturer’s job satisfaction can improve through grit and affective commitment. A new model about the effect of grit on job satisfaction mediating by affective commitment was confirmed. Therefore, researchers and practitioners can adopt a new empirical model to increase job satisfaction through grit and affective commitment in the future.
