Effects of Emotion on Binge-Watching
Previous studies have shown that binge-watching produces emotional effects. The current study examined whether there was an association between the frequency of binge-watching and negative and positive emotions. A survey was administered to 66 participants recruited from a Southern private institution. A multiple regression and correlation analysis were run on the data. Results from the analysis were significant, confirming our hypothesis that people who binge-watched more experienced negative emotions such as loss of control and dependency, and people who binge-watched less experienced more positive emotions. The implications do not show that binge-watching effects psychosocial outcomes. Suggestions for future research are discussed
Enthroning Responsible Democratic Culture in Nigeria through Christian Values
This paper looks at the devastating democratic activities in Nigeria. Governments in Nigeria have tended to be pre-occupied with power and its material perquisites. Corrupt politicians with questionable pedigree occupy the political sit of Nigeria. Corruption is the ocean which separates Nigeria from prosperity, and good living conditions such as good roads, social amenities, viable industries and employment opportunities. Nigerians require deep re-orientation. Christian values play vital role in any democratic government. Therefore, the potentials of enthroning responsible democratic culture in Nigeria through Christian values are the discourse of this paper
It’s More Than Nursing: The Experiences Of Psychological Safety of Pre-licensure Nursing Students Who Identify As Black, Indigenous, And People of Color
The healthcare environment mandates its staff are able to communicate freely and openly to provide high quality patient care leading to positive patient outcomes. As the largest healthcare profession and those who are at the bedside most often with patients, registered nurses play a vital role in ensuring these outcomes. As advocates for the most vulnerable, nurses must communicate often but before doing so, they must feel psychologically safe. Psychological safety is how one perceives the benefits, risks, and consequences of asking a question, sharing an opinion, reporting an error, or revealing one’s true self to others. It is a belief that one would not be shamed, punished, or humiliated for speaking up with questions, concerns, or mistakes. Although vital in the profession, psychological safety has been found to be essential to the learning process in nursing education. As the demographic of the United States changes and becomes more diverse, the healthcare workforce has been challenged with mirroring that population including nursing education. The minority experience in nursing school has been studied; what is not known is this population’s experiences of psychological safety. The purpose of this unique study was to know the experiences of psychological safety of nursing students who identify as Black, indigenous, and people of color (BIPOC). Eleven BIPOC, pre-licensure, Bachelor of Science in Nursing (BSN) students from across the United States participated in this qualitative, descriptive study. In-depth, semi-structured interviews were conducted, recorded, and analyzed by the researcher to identify repeated themes. Six themes were identified, giving nursing faculty a preliminary understanding of BIPOC nursing students’ experiences: (a) the past informs the present, (b) feeling dismissed, (c) it\u27s just too risky, (d) I will speak up for patients, (e) the learning community is key, and (f) I am needed! The findings revealed nursing faculty must do more to ensure BIPOC students feel included and wanted by enhancing their psychological safety and willingness to participate in class discussions. Furthermore, the discussion provided several recommendations for nursing faculty to create an environment that is not only inclusive of BIPOC students but celebrates the different perspective they bring. Increasing the psychological safety of BIPOC nursing students would benefit all students in learning to care for a highly diverse patient population
Quality indicators of excellence for doctoral program assessment in industrial education
The problem of this study was to generate, identify, and analyze a list of quality indicators for doctoral program assessment in the field of industrial education. The objective of the study was to produce objective indicators of excellence which would be used to assess industrial education doctoral programs;In the first phase of the study, a list of quality indicator variables was rated on a 99-point scale by a sample of industrial education faculty, doctoral students and recent doctoral alumni from 16 institutions. The resulting responses were factor analyzed to elicit (1) areas of (consensus) no significant differences in the main effects or interactions and (2) areas of variability. The results of the analysis yielded 60 indicators of consensus;In the second phase of the study, the results of the factorial analysis were resubmitted to a committee of industrial education experts in doctoral studies for review and recommendations. The committee\u27s reactions yielded 49 accepted quality indicators. These final indicators stem from the following programmatic dimensions: quality of the faculty, quality of the students, quality of the curriculum and instruction, and the quality of the facilities;The conclusion of this study, which was based on the findings related to specific research questions, was as follows: There was a consensus among the various respondents that the 49 variables constitute indicators of quality;In view of the fact that there were possibly other dimensions of quality which remained to be identified or that the identified quality indicators do not constitute the totality of quality considerations, further research in this area was highly recommended
Career readiness of final year agriculture students in tertiary institutions in South West region of Nigeria
Readiness to transit from school to work could arise from training at school. This study assessed the career readiness of final year agriculture students of tertiary institutions in the southwestern Nigeria. Multistage sampling procedure was used to select 240 students from universities (180) and polytechnics (60). Data were collected using structured questionnaire and analyzed with percentages, means and t-test. Results show that a higher percentage (51.1%) of final year students of university and polytechnic (71.7%) had a mean age of 24.5 years. Their perception of sufficiency of agriculture technical content for career readiness was about average for both universities and polytechnics respectively: theory (= 2.85; 2.72), practical (= 2.67; 2.78) and entrepreneurship (=2.53; 2.55). However, skills in Information Technology (IT), modern equipment and facilities usage and interactional/social skills were deficient for both institution types. Results further revealed that respondents in the universities showed the readiness to further their education/academics (= 2.24) while polytechnic showed more readiness to engage in agricultural enterprises (= 2.10). Most severe constraint to agriculture career readiness for the university students is inadequate government funding = 2.77) and for their counterpart low job prospects = 2.88). There was significant difference between university and polytechnics with respect to career readiness (t=-2.51; p=0.01) in which polytechnic students demonstrated more readiness. The plethora of constraints that militated against career readiness could be addressed through adequate funding to ensure more practical skills for university students.
 
Heavy Metals Concentrations in Five Brands of Lip Gloss and Mascara Cosmetics Sold and Used in Calabar, Cross River State, Nigeria
This study is evaluated the concentration of some toxic heavy metals present in selected cosmetics sold and used in Calabar, Cross River State, Nigeriausing aFlame Atomic Absorption Spectrophotometer (AAS), VGP 210 (BUCK Scientific) Model. The result revealed that the average concentration of the metals in mg/L ranged thus: Cadmium (0.012- 0.046), Chromium (0.002- 0.022), Lead (0.004- 0.024) and Nickel (0.140- 0.416). The concentration of Arsenic and Mercury was not detected, and were considered string variables in this study. From the results, the concentration of the metals detected were within the permissible limit of the World Health Organization (WHO) except Cadmium that was slightly above the WHO limit in one of the samples with a value of 0.046 mg/L. These results indicate that the selected cosmetics used in Calabar contains low amounts of the heavy metals analyzed in this study and may not pose any health risk for now, except that the accumulation of such little amounts over timedue to prolonged use of these cosmetics may cause harm.

Pore-scale modelling of biofilm activity in the underground storage of hydrogen
The storage of hydrogen in the subsurface to compensate fluctuations in energy demand and supply is considered an important part of future energy strategies. It has been observed that, within the period of storage, there is a partial conversion of hydrogen in the presence of carbon dioxide to methane. This has been attributed to the activity of microorganisms (archaea and bacteria) indigenous to the storage site. The talk will look at pore-scale phenomena including the interplay of different microbes (methanogens, acetogens, and acetotrophs) within a biofilm at the gas—water interface, the growth and decay of the multi-species biofilm, and the diffusion, consumption, and production of the dissolved gases. A numerical model with interface tracking, based on a volume-of-fluid method, is proposed for investigating these effects. The aim of the study is the description and quantification of the dominant processes which determine the amount of biomass such a reservoir can support and the rate at which the microorganisms produce methane as a contribution to explaining the observed field-scale phenomenon
Studies on industrially processed fruit juice and freshly prepared fruit juice sold in Enugu State, Nigeria
The sugar and mineral levels of industrially processed fruit juices (mainly 100% and 50% fruit juices) sold to consumers in Enugu state, Nigeria were determined and compared with that of freshly prepared fruit juices. The fruit juices tested included apple, orange, pineapple and red grape juices. The industrially processed and the freshly prepared fruit juices were tested for total soluble solid (TSS) content, fructose, glucose, sucrose, minerals such as sodium, potassium, magnesium, calcium, phosphorus, iron and heavy metals such as copper, zinc, arsenate and lead. Findings from the analysis of the TSS content of fruit juice samples demonstrated no significant (p > 0.05) difference between the industrially processed and freshly prepared fruit juices; however, differences in sugar and mineral levels between industrially processed and freshly extracted fruit juices were significant (p < 0.05). Industrially processed fruit juices contained higher glucose, sucrose, sodium, calcium, phosphorus, copper and zinc contents, and lower fructose, potassium and magnesium contents when compared to freshly prepared fruit juices. There was no significant (p > 0.05) difference in iron and arsenate contents of industrially processed fruit juices when compared with the freshly extracted juices. Lead (Pb) was not detected in any of the samples. This study demonstrated no quality issues of concern in relation to the products because all the parameters considered in the study were within the standard acceptable range for fruit juices and nectar.Keywords: Fruit juice, sugar content, mineral content, heavy metals, Enugu Stat
The relevance of microbial processes in geo-energy applications
The subsurface is a vast reservoir which we exploit in various ways. We extract energy in the form of oil/gas or heat from it. We use it for the storage of energy, e.g., in shallow geothermal applications or for the underground storage of natural gas. A lot of recent research has studied the potential for storing hydrogen (H2) in the subsurface. We also use the subsurface to dispose of energy-related waste, e.g., radioactive materials, carbon dioxide (CO2), and acid gas.For a long time, the subsurface was considered sterile below a few metres, probably stemming from work carried out in the 1950s which suggested that bacteria in Pacific sediments most likely disappeared somewhere just below 8m (Morita and ZoBell, 1955). This observation seems to have been extrapolated to the subsurface in general, but over time, as methods developed and microbiologists probed harder, this view changed, and it is now recognised that microbial communities exist at depths where the subsurface is exploited for most types of geo-energy. This raises questions about what sort of microbial community exists, how active it is, what limits and drives that activity and how this might impact geo-energy operations.Cited as: Ebigbo, A., Gregory, S.

Optimization of Atmospheric Distillation Unit of Warri Refinery Using Artificial Neural Network and Exergy Rate Profiles
In this paper, the operation of atmospheric distillation unit (ADU) of Warri refinery was optimized using Artificial Neural Network (ANN) method of optimization and exergy rate profiles (ERP). Optimization of ADU exergy efficiency using nine operating variables and ANN method of optimization improved exergy efficiency from 33% to 53%. The vapour and liquid exergy rate profiles in the distillation column were used to reveal points of inefficiency within the column and as a retrofit tool to suggest possible column modification alternatives for energy efficient operations. The exergy rate profiles in the column were found to be crossing each other. Optimization of the ADU when the crossing of the exergy rate profiles in the column was removed further improved ADU exergy efficiency from 53% to 60%. Artificial neural network was shown to be a powerful and suitable optimization method for solving constrained optimization problems such as in atmospheric distillation unit with several operating variables with constraints. Exergy rate profiles depict the driving forces between the liquid and the vapour states in a column and were shown to be a suitable tool for further improvement of ADU exergy efficiency
