An integrated evaluation framework for Environmental, Social, and Governance-driven social media performance through Multi-criteria Decision-Analysis

Social media is crucial in providing data for networking with individuals, companies, or industries. This study deals with the topic of Environmental, Social and Governance (ESG). These can be seen as a set of standards which impacts a corporation’s structure and performance. Twenty years ago, when ESG started to gain notoriety, ESG initiatives were labeled as a tool to ensure ‘ethical’ and/or ‘responsible’ investing. This study collects data from LinkedIn company profiles on the industry, the staff, the number of followers, and the state where the company has its headquarters. In addition, the media’s take on pending legislation on ESG was assessed. Based on data from 537 companies, indicators were created, either normalized, the median, or ranked, and analyzed with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The current work provides information on this variation of ESG activity within the different states in the USA. Multi-criteria Decision Analysis (MCDA) was applied by weighing four criteria. The overall assessment was presented depending on the combined weighted performance score of the four criteria. The results showed that 36% of the companies active within the ESG landscape represent the “Financial Services” and “Management Consulting” industries. 65% of the investigated sample represented companies with up to 10 employees. Moreover, eight states perform well on both median of staff and followers (in alphabetical order: Michigan, Mississippi, Missouri, New Hampshire, New Mexico, Ohio, Oklahoma, and Wisconsin). Lastly, through the MCDA method, it was also observed that there are not many variations when different weights are applied to the four criteria: i.e., “the normalized number of companies by state,” “the median of the followers of the company per state,” “the median of the staff of the company per state,” and the “sentiment of the legislation.” Finally, the top five highly ranked states considering ESG visibility on LinkedIn through their companies are Ohio, Michigan, Delaware, Georgia, and Pennsylvania. The results indicate that companies can more proactively advertise themselves as compliant with current ESG principles. This methodology can also be applied to other topics and regions to assess online activity in line with existing indicators.

Enrichment culture evaluation and characterization of Streptococcus agalactiae among pregnant women in Japan.

Introduction. Maternal screening tests and prophylactic antibiotics are important to prevent neonatal and infant group B streptococcal (GBS) infections.Hypothesis/Gap Statement. The performance of enrichment broth media for GBS screening that are available in Japan is unclear. Whole-genome data of GBS isolates from pregnant women in Japan is lacking.Aim. The aim of this study was to compare the protocol performance of six enrichment broths and two subculture agar plates, which were all available in Japan, for GBS detection. In addition, we showed whole-genome data of GBS isolates from pregnant women in Japan.Methodology. We collected 133 vaginal-rectal swabs from pregnant women visiting clinics and hospitals in Nagasaki Prefecture, Japan, and compared the protocol performance of 6 enrichment broths and 2 subculture agar plates. All GBS isolates collected in this study were subjected to whole-genome sequencing analysis.Results. We obtained 133 vaginal-rectal swabs from pregnant women at 35-37 weeks of gestation from 8 private clinics and 2 local municipal hospitals within Nagasaki Prefecture, Japan. The detection rate of the protocol involving the six enrichment broths and subsequent subcultures varied between 95.5 and 100 %, depending on the specific choice of enrichment broth. The GBS carriage rate among pregnant women in this region was 18.8 %. All 25 isolates derived from the swabs were susceptible to penicillin, whereas 48 and 36 % of the isolates demonstrated resistance to erythromycin and clindamycin, respectively. The distribution of serotypes was highly diverse, encompassing seven distinct serotypes among the isolates, with the predominant serotype being serotype V (n = 8). Serotype V isolates displayed a tendency towards increased resistance to erythromycin and clindamycin, with all resistant isolates containing the ermB gene.Conclusion. There was no difference in performance among the culture protocols evaluated in this study. GBS strains isolated from pregnant women appeared to have greater genomic diversity than GBS strains detected in neonates/infants with invasive GBS infections. To confirm this result, further studies with larger sample sizes are needed.

Underwater sound absorption characteristics of water-saturated porous materials

In this research, the underwater sound absorption performance of porous media saturated with water is investigated through long straight tubes (LSTs) with circular cross-section and sintered fibrous metals (SFMs) containing complex pores, and effective underwater sound absorption capability is demonstrated theoretically, numerically and experimentally. Specifically, the theoretical model for LSTs, verified by direct numerical simulations (DNSs), reveals that much smaller pore diameter and much larger layer thickness of porous material is needed to gain high waterborne sound absorption coefficient than to obtain large airborne sound absorption coefficient. Besides, to examine the sound absorption capacity of realistic porous materials, SFMs backed with a finite cavity are experimentally measured under 7 different hydrostatic pressures in a water-filled tube, and numerically characterized via multi-physics couplings. Insensitivity of effective sound absorption capability to high pressure is established, which stems from the different underwater wave energy consumption mechanism (i.e. viscous-thermal effect) of porous materials from conventional rubber kind of underwater sound absorption materials. Physically, porous materials possess great potential in developing the next generation of high-performance underwater sound absorption materials.

Design of inherently polarized nanofiber-based membranes for superior filtration performance

As airborne particulate matter (PM) such as pathogens and ultrafine dust threaten the human health, air quality control technologies are becoming increasingly important. Herein, poly(vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) nanofibers with various fiber diameters and pore size distributions were prepared using various compositions of volatile (acetone) and less volatile N,N-dimethylformamide (DMF) solvent mixtures to design the optimum filtration media. Morphologies and molecular configurations were examined thoroughly with respect to the filtration performance. Among the various solvent compositions, the specimen prepared with the lowest DMF content (denoted as ePVdF-HFP55) showed the best filtration performance, with a filtration efficiency of 99.95% and a pressure drop of 29.0 mmH2O. The quality factor (QF) of ePVdF-HFP55 (0.0266 Pa−1) is superior to that achieved in electrospun nanofibrous media in previous works. In addition, the QF was further improved to 0.0276 Pa−1, with a remarkably reduced resistance of 14.45 mmH2O achieved by employing the layered nanofiber media with a PVdF-HFP top layer. Our work demonstrates that optimization of the inherently polarized nanofiber synthesis is a fruitful pathway to enhancing the filtration performance of air filter media.

Optimizing germination: comparative assessment of various growth media on dragon fruit germination and early growth

Dragon fruit (Selenicereus undatus), known for its captivating appearance and remarkable nutritional profile, has garnered considerable attention in recent years. Despite its popularity, there's a dearth of research on optimal conditions for seed germination and early growth stages such as seedling shoot length, which are crucial for optimal crop yield. This study aims to bridge this gap by evaluating various growing media's performance on dragon fruit germination and early growth stages. Dragon fruit seeds were obtained from local markets in Pakistan and evaluated in five different growing media: cocopeat, peat moss, sand, vermiculite, and compost. Germination parameters were observed for 45 days, including seed germination percentage, mean germination time, and mean daily germination percentage, among others while early growth was monitored for 240 days. Statistical analysis was conducted using ANOVA and Tukey’s HSD test. Significant differences were found among the growing media regarding germination percentage, mean germination time, and mean daily germination. Vermiculite exhibited the highest germination rate (93.33%), while compost showed the least (70%). Peat moss and sand media facilitated rapid germination, while compost showed slower rates. Stem length was significantly influenced by the growth media, with compost supporting the longest stems. Vermiculite emerged as the most effective medium for dragon fruit seed germination, while compost showed slower but steady growth. These findings provide valuable insights for optimizing dragon fruit cultivation, aiding commercial growers and enthusiasts in achieving higher yields and quality. Further research could explore additional factors influencing dragon fruit growth and development.

Increased customer engagement through social media can also be strengthened by the Brand Exposure strategy applied in marketing through social media.

Numerical Study on Fluid Flow Behavior and Heat Transfer Performance of Porous Media Manufactured by a Space Holder Method.

The velocity field and temperature field are crucial for metal foams to be used as a heat exchanger, but they are difficult to obtain through physical experiments. In this work, the fluid flow behavior and heat transfer performance in open-cell metal foam were numerically studied. Porous 3D models with different porosities (55-75%) and pore sizes (250 μm, 550 μm, and 1000 μm) were created based on the porous structure manufactured by the Lost Carbonate Sintering method. A wide flow velocity range from 0.0001 m/s to 0.3 m/s, covering both laminar and turbulent flow regimes, is fully studied for the first time. Pressure drop, heat transfer coefficient, permeability, form drag coefficient, temperature and velocity distributions were calculated. The calculated results agree well with our previous experimental results, indicating that the model works well. The results showed that pressure drop increased with decreasing porosity and increasing pore size. Permeability increased and the form drag coefficient decreased with increasing porosity, and both increased with increasing pore size. The heat transfer coefficient increased with increasing velocity and porosity, whereas it slightly decreased with increasing pore size. The results also showed that at high velocity, only the metal foam close to the heat source contributes to heat dissipation.

Investigating The Impact of Digital Technology on Adolescent Identity Formation on Selected Students in SAIS: A Psychological Approach

Teenagers are today living in a hybrid world that connects digital spaces to offline contexts; we are amid a global shift where digital "screens" are no longer only entertainment devices yet a major distraction. Adolescence is a period of self-actualization, self- integration, and, in the current era, consistent social media performance. Conflicts in the identity vs. role confusion stage of Erik Erikson and James Marcia theory of identity statues model are addressed throughout this research. A survey, sent to Sharjah American International School high school students, explores the aftermath of the online metaverse impact on their identity development. The aim of the present study was to examine the interrelationships between adolescent media activity and identity development through studying behavioral outcomes to psychological analyze results. Participating in the study were 19 adolescents ages 13 to 19 (mean age 17). The results showed identity was however negatively associated with time spent using the network on social media and communicating. On the other hand, identity style was also positively associated with adaptive media- related cognitions, such as benefiting from the online metaverse to absorb new knowledge constantly. The results are discussed regarding practical implications and recommendations for enhancing parenting styles and guidance of adolescents.

A Servant of the Authorities or an Ally of Civil Society? The Role Perceptions and Role Performance of Local Interloper Media

ABSTRACT The study explores the journalistic role perceptions and role performance of local interloper media practitioners in Finland. The examined media include non-commercial outlets funded by a city administration or other local authorities as well as commercial online-only outlets. The outlets are conceptualised as interlopers because they apply journalistic forms, styles and methods in their content but do not necessarily consider themselves as journalists or adhere to the ethical guidelines of journalism. The outlets’ role performance is analysed in their published content, while the practitioners’ role perceptions are analysed via semi-structured interviews. The analysis reveals that the non-commercial practitioners primarily perceive and perform the loyal facilitator role, whereas the commercial practitioners serve the disseminator role. The watchdog role is virtually absent among all the examined outlets. The lack of critical perspectives indicates a selective and strategic adoption of journalistic roles aimed at enhancing public relations efforts and appearing more trustworthy and interesting to audiences or advertisers. The investigated outlets and practitioners therefore challenge the monopoly of local legacy news media over local news. Their adoption of certain journalistic roles while abstaining from critical scrutiny of local authorities shows a tendency to disguise political or private ambitions as public interest news.

Interplay of Corporate Sector, Politics, and Media in Shaping News Contents in Nepal

This paper examines the intricate implications arising from the symbiotic relationship among the corporate sector, politics, and media in shaping news content in Nepal. This study analyzes the dynamics and interplay between politics, corporate sectors and the influence they can have on the media content largely within the privately run for-profit media outlets in Nepal. The theoretical foundation for this study has been rooted in Habermas’ public sphere model of mass media (1989). The study revealed that vested corporate and political interests are hugely influential both in shaping the opinion and performance of the news media. Besides, the corporate influence, the ideological division of media outlets and journalists not only raises ethical concerns but also the quality of discourse. Taken together, they only undermine the very credibility of the media institutions which does not allow them to become what Habermas calls the public sphere.

A novel pulse-jet cleaning method to effectively extend the lifetime of pleated filter and reduce dust emission

To solve the problem of poor cleaning effect of pleated filter, this study explored in detail the impact of various cleaning method on the filtration and cleaning performance of the filter media in clean-on-demand mode. Furthermore, the clogging mechanism of the filter and the deposition structure of dust on the filter media were analyzed based on the effective filtration area ratio and true resistance coefficient calculated by the proposed model. The results demonstrated that for the constant pulse-jet cleaning pressure (PJCP), increasing PJCP was more conducive to removing dust deposited on the filter media and improving regeneration efficiency, although higher PJCP increased power consumption. Different from the thick primary dust layer formed on the filter surface under the constant PJCP of 0.3 MPa, the dust was mainly deposited inside the filter media under the constant PJCP of 0.5 and 0.7 MPa. In contrast, stepwise increasing PJCP was more effective in cleaning and regenerating the filter media, which was reflected in further extending the filter lifetime, increasing the processing air volume and reducing the dust emission concentration with acceptable energy consumption. Moreover, the filter media mainly clogged itself and formed a medium thickness primary dust layer on the filter surface.

Acidic Derivatization of Thiols Using Diethyl 2-Methylenemalonate: Thiol-Michael Addition Click Reaction for Simultaneous Analysis of Cysteine and Cystine in Culture Media Using LC-MS/MS.

Cysteine (Cys) and its oxidized form, cystine (Cys2), play crucial roles in biological systems and have considerable applications in cell culture. However, Cys in cell culture media is easily oxidized to Cys2, leading to solubility issues. Traditional analytical methods struggle to maintain the oxidation states of Cys and Cys2 during analysis, posing a significant challenge to accurately measuring and controlling these compounds. To effectively control the Cys and Cys2 levels, a rapid and accurate analytical method is required. Here, we screened derivatizing reagents that can react with Cys even under acidic conditions to realize a novel analytical method for simultaneously determining Cys and Cys2 levels. Diethyl 2-methylenemalonate (EMM) was found to possess the desired traits. EMM, characterized by its dual electron-withdrawing attributes, allowed for a rapid reaction with Cys under acidic conditions, preserving intact information for understanding the functions of target compounds. Combined with LC-MS/MS and an internal standard, this method provided high analytical accuracy in a short analytical time of 9 min. Using the developed method, the rapid oxidation of Cys in cell culture media was observed with the headspace of the storage container considerably influencing Cys oxidation and Cys2 precipitation rates. The developed method enabled the direct and simplified analysis of Cys behavior in practical media samples and could be used in formulating new media compositions, ensuring quality assurance, and real-time analysis of Cys and Cys2 in cell culture supernatants. This novel approach holds the potential to further enhance the media performance by enabling the timely optimal addition of Cys.
