The Impact of a Computerized Cognitive Training on Healthy Older Adults: A Systematic Review Focused on Processing Speed and Attention

As the world around us evolves into one with an aging population, it is essential to consider various strategies to reduce challenges encountered by older adults. Cognitive declination can be diminished through computerized cognitive interventions that employ frameworks of neuroplasticity to improve specific cognitive abilities. The speed of processing Brain HQ training by Posit Science Corporation has been frequently utilized for research purposes but its sole clinical validation of literature has yet to be reviewed. Therefore, the aim of this systematic review is to identify the benefits this training program confers to various cognitive abilities and everyday functions in addition to summarizing the similarities and differences across intervention characteristics. A search on a shared database of computerized cognitive training based research containing relevant studies from this program, PubMed and Google Scholar revealed a final list of 23 studies that were analyzed. Information obtained were segregated by benefits conferred to near transfer cognitive dimensions of processing speed and attentional domains, far transfers to other cognitive abilities and everyday functioning variables as well as intervention characteristics such as training exposure, adherence and implementation. Overall, most studies possessed low risk of bias and were of good quality. Small to large effect sizes were noted in near transfers to trained cognitive abilities while small to moderate effects sizes were observed in far transfers to untrained cognitive abilities and everyday functioning variables. Sufficient exposures at a laboratory, of four exercises and above, over a duration of 60 minutes or more per session and a total of more than 25 hours of training produces better effectiveness of the training program itself. Despite the presence of other biases in each individual research, current evidence supports the notion that Brain HQ is a clinically meaningful cognitive intervention that can promote healthy aging among older adults.
Corporate Governance Disclosure and Ownership Concentration in Non-Financial Listed Firms in Kuwait Stock Exchange (KSE)

This paper demonstrates the effect of ownership concentration among large shareholders on corporate governance disclosure (CGD) in Kuwait. Secondary data were collected from 82 non-financial firms listed on the Kuwait Stock Exchange in 2018. The study used an ordinary least square regression. The 35-item CGD index served as the dependent variable while the independent variables comprised four variables of ownership and four control variables. Ownership concentration by institutions and government negatively affected the CGD index; ownership concentration by blockholders or families (individuals) had no significant impact on the CGD index.

Awareness, handling and storage factors associated with aflatoxin contamination in spices marketed in Dar es Salaam, Tanzania

A structured questionnaire was used to collect information of awareness, knowledge and practices associated with aflatoxin contamination in spices from 30 retailers in Dar es Salaam. Aflatoxin contamination in spices was analysed using high performance liquid chromatography (HPLC) with fluorescence detection using post column derivatization. Data were statistically analysed to assess factors associated with aflatoxin contamination in the study community. 58% of the spice samples were contaminated and the mean of total aflatoxin level in ginger, cinnamon, cloves and cardamom was 2.67, 2.88, 2.79 and 2.26 μg/kg, respectively. Significant majorities (96.7%) of the respondents were not aware of aflatoxin contamination of spices during storage and its effect on health. Farmers as source where spices were procured and storage time of more than 14 days showed significant association with aflatoxin contamination with odds ratio (OR) = 0.178, 95% confidence interval (CI) = 0.061-0.525, P=0.002 and OR=3.608, 95% CI=1.099-11.845, P=0.034, respectively. This is the first report of aflatoxin contamination in spices consumed in Tanzania. The levels of contamination are high and associated spices that was procured from farmers and long storage time. This calls for urgent raising of awareness and knowledge on good management practices for prevention of aflatoxin contamination of spices in Tanzania.
Spin evolution of Ceres and Vesta due to impacts

All asteroid spins evolve due to collisions. Geophysical analysis (Mao and McKinnon 2018b) implies Ceres might have been modestly despun (by ~6.5%) by impacts. Vesta’s postaccretion rotation rate, before the formation of the Veneneia and Rheasilvia basins, has also been proposed to have been higher (by ~6%) than today (Fu et al. 2014). We have designed Monte Carlo simulations to investigate Ceres’ and Vesta’s plausible spin evolution by impacts. We use the main belt asteroid size–frequency distribution, Ceres’ and Vesta’s cratering records, and their present‐day impact velocity probability distributions to quantify possible spin histories. We consider dynamical effects from escaping ejecta, adopt mass‐velocity scaling laws for two endmember surface materials (porous and nonporous), and track potential catastrophic disruptions. Results show that Ceres’ spin period likely changed by a fraction of an hour (up or down) compared with its “initial,” accretional spin, mostly due to large impacts. Different surface materials do not yield statistically distinguishable final spin distributions, but imply opposite crustal evolutions where Ceres loses/accretes mass, depending on surface porosity; as much as several 100 m worth of exogenous material, globally averaged, can be accreted if the surface remains porous. Vesta’s final Monte Carlo spin distribution is more concentrated around its “initial” value, possibly implying a more relict spin state than Ceres. However, explicitly modeling the angular momentum changes wrought by Vesta’s two existing planetary‐scale impact basins shows that their formation alone can account for Vesta’s proposed spindown, although spinup is a much more likely outcome because of the scale and location of the impacts.
Exploring moral distress among critical care nurses at a private hospital in Kwa-Zulu Natal, South Africa

Background Moral distress resulting from frequent and intense exposures to morally challenging encounters with critically ill patients, their families and other healthcare professionals negatively impacts on the personal and professional wellbeing of critical care nurses. Objectives To determine the frequency, intensity and overall severity of moral distress among critical care nurses working in the critical care environment of a private hospital in the eThekwini district of KwaZulu-Natal Province, South Africa. Methods A descriptive survey was conducted using a 21-item moral distress scale revised questionnaire. We assessed the influence of sociodemographic variables of the respondents on the moral distress composite scores. Results The moral distress composite scores of the 74 critical care nurses who completed the questionnaires ranged from 0 - 303 out of a possible 336. The mean (standard deviation (SD)) composite moral distress score was 112.12 (73.21). Analysis of the relationship between sociodemographic variables and the moral distress composite scores revealed that female respondents experienced higher distress scores than males (p=0.013). There was an inverse relationship between composite scores and an increase in age (p=0.009) and years of service (p=0.022). Conclusion The mean composite score of the critical care nurses was suggestive of moderate levels of moral distress. Counselling services and empowerment skills training are advocated to support critical care nurses to manage moral distress. Contributions of the study Findings of the study can be used to identify sources of the distress, potential interventions, as well as the risks and benefits of taking action to assist critical care nurses to overcome moral distress.
Migration of phosphate into aggregated particles of ferrihydrite

SUMMARY The slow reaction of phosphate with aggregated particles of ferrihydrite, after initial rapid phosphate sorption, was investigated by measuring the changes, with time and temperature, in the amount of phosphate sorbed, and the extractability of the sorbed phosphate. The ferrihydrite was, subsequently, recovered and examined by infra–red spectrometry (IR) and electron probe micro–analysis. Phosphate continued to react with ferrihydrite for at least 90 d at 25°C, but was completely recovered by extraction with 0.1 m NaOH. The IR spectra of sorbed phosphate was insensitive to the temperature and duration of the reaction. Electron probe micro–analysis of the aggregates showed that phosphate migrated to surface sorption sites within the aggregated particles of ferrihydrite. There was no evidence for the formation of surface coatings of ferric phosphate, for changes in the type of bonding, or for penetration of phosphate into the crystal lattice. The slow reaction was attributed to the migration of phosphate to surface sorption sites of decreasing accessibility within aggregates.
Factors Related to Academic Stress During the Covid-19 Pandemic in Nursing Students of UPN Veteran Jakarta

Background: Academic stress is one of the biggest health problems that have an impact on academic performance. Students become a group that is vulnerable to the stress that comes from academic life. Academic stress that is usually experienced by students is due to academic responsibility. The online learning system that has changed during the Covid-19 pandemic requires students to get more assignments and a busy lecture schedule. Method: This study used a cross-sectional study design. The respondents were 175 students using the accidental sampling technique. The instrument used was a questionnaire consisting of demographic data and a statement regarding the level of academic stress with the modified Depression Anxiey and Stress Scale 42. Result: From the results of statistical tests, it was found that most of the respondents had a moderate stress level (34.3%), the variable age value p-value = 0.001, college load p-value = 0.045, achievement index p-value = 0.302, and residence status p-value = 0.166. Conclusion: So that there is a relationship between age and study load with academic stress on students. Students who cannot adapt to environmental changes will result in impaired ability to adapt to stressors received from the academic process.
Superstoichiometric Alloying of H and Close‐Packed Fe‐Ni Metal Under High Pressures: Implications for Hydrogen Storage in Planetary Core

Although high pressure enables alloying between hydrogen and iron, hydrogen‐to‐iron molar ratio (H/Fe) so far found in experiments is mostly limited to 1 in the close‐packed iron metal under high pressure. We report a H/(Fe + Ni) ratio of 1.8 ± 0.1 from (Fe,Ni)Hx (or x ≥ 1.8) quenched from liquid, exceeding the amounts so far reported for densely packed Fe alloys. From the metastable behavior of the frozen (Fe,Ni)Hx liquid during decompression, we infer that the amount is a lower bound and therefore even a greater amount of H can be dissolved in the liquid part of Fe‐rich cores of planets. The significant H storage capacity of liquid Fe‐Ni alloy is important to consider for potential storage of H in the interiors of low‐density planets as well as rocky planets.
Green Synthesis of Renewable Dimethyl Terephthalate-Like Monomer from Eugenol

Dimethyl terephthalate, a diester monomer derived from petroleum-based resources, plays important role in the production of polyester such as polyethylene terephthalate (PET), resins for polyester, fibres, and films as well as engineering polymers. High demand on PET together with environmental concerns require to find alternative for renewable monomers urgently whenever or wherever to substitute the exhausting crude oil-based monomers. A simple and highly efficient method to prepare PET analogue monomer, methyl 2-[2-methoxy-4-[3-(2-methoxy-2-oxoethyl)] thiopropyl]phenoxy acetate (4), from renewable eugenol is described. The key step involves successive Williamson etherification, esterification, to be followed by thiol-ene reaction. Remarkably, it turned out that the thiol-ene reaction has proven to be effective in the introduction of the ester group to the olefinic substrate without the use of solvent and initiator leading to diester 4. The technique offered here comprises advantages i.e. excellent yields, mild reaction condition, and easy to perform, thus, provide a sustainable alternative to synthesize diester from eugenol.
Synthesis of sesquiterpene allylic alcohols and sesquiterpene dienes from Cupressus bakeri and Chamaecyparis obtusa

Five muurolane (1–5), one nor-seco-muurolane (6) and one nor-muurolane (7) sesquiterpene natural products recently reported from Cupressus bakeri have been obtained by chemical synthesis together with the unnatural 7-epimeric amorphane analogues of four of these sesquiterpenes (15, 16, 18 and 19). The conversion of sesquiterpene allylic tertiary alcohols 1, 2, 15 and 16 into regioisomeric sesquiterpene dienes 3–5 and 17–20 was investigated in vitro by NMR and the mechanism for such dehydrations and their relevance to the origins of sesquiterpene dienes which have been reported as natural products (such as 3–5) is discussed.
The Challenging Experiences of Nursing Students in South Korea: A Qualitative Inquiry of International Students

South Korea is one of the popular destinations for international students to achieve their education. In 2019, due to the development of the Study Korea Project, more than 160 thousand international students were studying at one of the Korean colleges and universities. Due to sociocultural differences (in language, religion, race, and nationality), international students often encounter difficulties caused by discrimination, bias, and stigma during their time in Korea. In other words, while classrooms may be ready for the enrolment of additional international students, local communities, support services, and residents are not. Based on the Social Stigma approach, the researcher collected qualitative interview data of 99 international students from China, Vietnam, Mongolia, Japan and the United States, who are majoring in nursing about their sense-making process and the experiences in Korea. The finding indicated that almost all participants experienced discrimination due to their foreign status, skin colour, language, nationality, and place of origin insides and outsides of the university environment. Furthermore, all expressed negative academic and living experiences in the region and will leave the region once they completed their education. The results demonstrate the necessity for various parties in Korea, including school leaders, government agencies, policymakers, faculty heads, and NGOs, to rethink and reform the country's approach to attracting international students.
Les écueils de la transition universitaire : validation française du questionnaire des obstacles académiques (QoA)

First year experience is an extensive topic of investigation in the field of educational psychology. Most of the research addressed this question through the specific perspective of the student and identified major individual predictors of achievement and retention. Yet, the analysis of the contextual obstacles to student’s adjustment has been left out of the picture. In order to overcome this limitation, the present manuscript investigated the validity of the French version of a questionnaire based on the critical requirement taxonomy from Trautwein and Bosse (2017)? This questionnaire depicted the contextual obstacles to first year student’s adjustment. A sample of more than 1.200 students were used to test the validity. Exploratory and confirmatory factor analysis sustained the 10 factors structure advocated by the original taxonomy. Results also showed a good internal consistency of the 10 factors. Predictive validity was also tested on motivation, social integration and academic achievement. The added value of this questionnaire for the field were discussed at the end of the paper.
The vegetation of a historic road system in the suburban area of Monte Pellegrino (Palermo, Sicily)

Knowledge of the processes by which plants colonize old structures is a key element for nature-based design both in urban and suburban contexts. This paper analyses the natural vegetation on walls and in other microhabitats of the roadway structures of Monte Pellegrino (606 m a.s.l.) near Palermo (Sicily), built in the first half of the 1900s. The historical road has particular construction and architectural features, and its characteristics have been maintained to this day. The route, approximately 16 kilometers long, is well integrated within a site of high naturalistic value which has been designated as a Special Area of Conservation (ITA020014) of the Natura 2000 network, and it is also a regional natural reserve. The survey was carried out on different homogeneous ecological contexts based on different microhabitats (masonry retaining walls, masonry guardwalls, road margins, and rock cut slopes) which are diversified according to other environmental factors (building materials, inclination, height, and exposure). The phytosociological and statistical analysis has led to the description of six new associations (Crepido bursifoliae-Parietarietum judaicae ass. nov., Athamanto siculae-Parietarietum judaicae ass. nov., Helichryso panormitani-Hypochaeridetum laevigatae ass. nov., Diantho siculi-Helichrysetum panormitani Gianguzzi ass. nov., Olopto miliacei-Pennisetetum setacei Gianguzzi ass. nov., Teucrio flavi-Rhoetum coriariae Gianguzzi ass. nov.) and one sub-association (Rhamno alaterni-Euphorbietum dendroidis Géhu & Biondi 1997 artemisietosum arborescentis subass. nov.). Other chasmophytic formations (Centranthetum rubri Oberd. 1969, Antirrhinetum siculi Bartolo & Brullo 1986) were reported for the first time in this area.
Response Times of Motorcycle Ambulances during the COVID-19 Pandemic

BACKGROUND: Motorcycles (motorlance) are often deployed as ambulances to the scene of an emergency to reduce response time. The COVID-19 pandemic has affected emergency medical services (EMS) in Thailand in many respects, and this study was conducted to examine its effect on motorlance operation time. AIM: The aim of the study was to examine motorlance operation time during the COVID-19 pandemic in comparison to normal periods. METHODS: This cross-sectional study examined all EMS motorlance operations dispatched from Srinagarind Hospital (Thailand). Data were collected from the Srinagarind Hospital EMS operation database and hospital information database system. Data from June 1, 2018, to December 31, 2019 (normal period) were compared with those from January 13 to April 21, 2020 (COVID-19). RESULTS: Eight hundred seventy-one EMS operations were examined over two periods. Mean patient age during the COVID-19 pandemic was 41.5 ± 6.2 years, and 54.6% (n = 59) were male. Average response time was 6.20 ± 1.35 min during the normal period and 3.48 ± 1.01 min during the pandemic (p = 0.021). Transport time was also significantly shorter during the latter period (2.35 vs. 5.20 min). CONCLUSIONS: Motorlance response and transport time during the COVID-19 pandemic were significantly shorter than usual.
Low-frequency vibrational modes of benzoic acid investigated by terahertz time-domain spectroscopy and theoretical simulations

In this paper, the low-frequency vibrational modes of crystalline benzoic acid (BA) have been investigated by terahertz time-domain spectroscopy (THz-TDS) and theoretical simulations based on the linearity combination of atomic orbital within the Density Functional Theory (DFT) as well as ab initio molecular orbital method at second-order Moller-Plesset Perturbation Theory (MP2) level for single molecule and dimer. Experimentally, a series of prominent absorption features of pure benzoic acid relevant to intra- and inter-molecular vibrational modes have been obtained below 4 THz at room temperature. For the theoretical simulations, geometry-optimization results of bond lengths and dihedral angles in both BA monomer and dimer are very close to experimental neutron diffraction measurements. Furthermore, the simulation results demonstrate absorption profile centered at 1.89 THz contains low-frequency modes of Ph-COOH twisting due to intramolecular motion and cogwheel owing to intermolecular motion. All the intra- and inter-molecular vibrational modes measured have also been assigned.
