Customers’ intentions to use mobile payment service: a comparative study of payment system types

With the development of mobile technology, mobile payment services are some of the fastest growing transaction systems in the industry. However, studies of mobile payment systems have focused on retailing settings; few studies have examined them in the service setting. Thus, this research explores the effects of mobile payment system–related characteristics (i.e. perceived ubiquity, perceived security, perceived ease of use, perceived cost) on customers’ intentions to use mobile payments in the restaurant setting. An online survey (n = 370⁣) was conducted in the United States. The data are analyzed by partial least squared-structured equation modeling. The study results demonstrate that restaurant customers’ intentions to use mobile payment are largely determined by perceived usefulness, trust, and attitude. Among them, perceived usefulness is the most important factor for predicting customers’ intentions across different types of mobile payment systems (i.e. mobile proximity payment, mobile peer-to-peer payment, mobile in-app payment). These findings have useful theoretical and practical implications for better understanding customers’ mobile payment usage behavior.
Expression of early transcription factors by mesenchymal stem cells derived from ovine umbilical cord Wharton’s jelly

Mesenchymal stem cells (MSCs) are multipotent stem cells that can differentiate into mesodermal lineages. Despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow MSCs has remained to be challenged. In this study, we utilized ovine umbilical cord Wharton’s jelly as a primary source for isolation of MSCs since it is a rich source of MSCs and no ethical issues were involved. Ovine umbilical cord Wharton’s jelly segments were digested enzymatically and cultured in vitro in culture medium. In addition to the study of their morphology and colony forming units, the expression of pluripotent stem cell markers by the isolated MSCs were also studied. The MSCs were plastic adherent, clonogenic and their morphology were polygonal, star shaped and fibroblast like. They revealed a strong expression of pluripotent stemness markers Oct4, Sox2, Nanog and Alkaline phosphatase. These cells confirmed their ability of self-renewal by expressing Sox2 gene and their properties of pluripotency and plasticity by expressing Oct4, Nanog and Alkaline phosphatase. The study revealed that Wharton’s jelly is a rich source of stem cells with stemness properties and mesenchymal like morphology and could be used as an alternate for the bone marrow derived MSCs for cell based regenerative therapies.
The Relationship of Integrated Geriatric Assessment and Effective Communication Towards Holistic Nursing Care With Caring Nurse Behavior as an Intervening Variable at Islamic Hospital Siti Khadijah Palembang City

In the world of health, Holistic Nursing Care is a standard with a multi-disciplinary approach through integrated and holistic assessment. Geriatric patients have complex needs that must be identified to address the needs that must be met by a hospital service to provide patient survival, quality of life and satisfaction. Holistic nursing care is influenced by several variables such as integrated geriatric assessment and effective communication. In addition to these two variables, there are other variables that can affect this relationship, one of which is the caring behavior of nurses. The purpose of this study was to analyze the relationship between Integrated Geriatric Assessment and Effective Communication of Holistic Nursing Care with Nurse Caring Behavior as Intervening Variables at Siti Khadijah Islamic Hospital, Palembang City. This research is explanatory research with a quantitative approach in the form of causality using 7 hypotheses with a sample of 80. The conclusion in this study is that there is a significant relationship between integrated geriatric assessment and effective communication on nurse caring behavior and holistic nursing care, besides that caring behavior turns out to be able to Intervene a significant relationship between integrated geriatric assessment and effective communication of holistic nursing care. Meanwhile, another significant relationship is between the caring behavior of nurses and holistic nursing care at Siti Khadijah Islamic Hospital, Palembang. The theoretical implications of this study will prove the effect of research variables and managerially will further improve the evaluation system for the quality of nursing care for geriatric services in hospitals and the overall management of geriatric patients for healthy old age.
Experimental investigation of clogging mechanism of pervious concrete made with variable aggregate gradations

In this study, the clogging mechanism of pervious concrete was evaluated using three different cloggers such as, Sand (S), Clay (C), and combination of sand and clay (S &C). The clogging mechanism was performed through falling head permeability apparatus, using clogger sediment load at the rate of 50, 150, and 200 grams in repetitive clogging cycles. It was observed from the results that combined (S & C) clogger shows overall critical results of clogging as 80% of the clogging was seen in 3 to 4 cycles. Moreover, it was observed from the results that pervious concrete mix made with R- type of aggregate gradation shows optimum compressive strength of the order of 8.6, 15.9, and 17 MPa at 7, 28 and 56 days of curing. Furthermore, the visual inspection test shows that clogging by clay clogger shows an even distribution of sediment on the whole length of the sample.
An evaluation of sweet sorghum as a sugar crop in the Midlands mistbelt.

Moench) varieties, RIO, RAMADA and ROMA were grown experi- mentally from seed that was imported from the USA and subsequently from seed that was bulked locally, in the mist- belt of the Natal Midlands. ROMA, the tallest and latest maturing variety outyielded the other two sorghum cultivars in a variety trial and in observation and bulking plots. In another trial ROMA was sown on three dates in spring and the crop was harvested either at the hard-dough stage or one month later. Yields decreased rapidly with delays in sowing. This was due not only to a reduction in the growing period of the crop but also to a lower rate of growth per unit time. Sucrose yields remained fairly constant between harvests but juice purities and sucrose contents rose considerably when harvesting was delayed. Of the herbicides tested, atra- zine sprayed pre-emergence at a rate of 3 kg ailha, was the most successful but gave limited control of grasses. Although in some respects the performance of sweet sorghum com- pared reasonably well with that of sugarcane in the Natal Midlands, it was concluded that sorghum would be of more use in the drier, warmer areas that are marginal for sugar- cane. Introduction "Sorgo" is the vernacular in North America for the juiciest and sweetest variants found in many species of the genus So,rghum and for S. bicolor
Six-year source apportionment of submicron organic aerosols from near-continuous highly time-resolved measurements at SIRTA (Paris area, France)

Abstract. Organic aerosol (OA) particles are recognized as key factors influencing air quality and climate change. However, highly time-resolved long-term characterizations of their composition and sources in ambient air are still very limited due to challenging continuous observations. Here, we present an analysis of long-term variability of submicron OA using the combination of an aerosol chemical speciation monitor (ACSM) and a multiwavelength Aethalometer from November 2011 to March 2018 at a peri-urban background site of the Paris region (France). Source apportionment of OA was achieved via partially constrained positive matrix factorization (PMF) using the multilinear engine (ME-2). Two primary OA (POA) and two oxygenated OA (OOA) factors were identified and quantified over the entire studied period. POA factors were designated as hydrocarbon-like OA (HOA) and biomass burning OA (BBOA). The latter factor presented a significant seasonality with higher concentrations in winter with significant monthly contributions to OA (18 %–33 %) due to enhanced residential wood burning emissions. HOA mainly originated from traffic emissions but was also influenced by biomass burning in cold periods. OOA factors were distinguished between their less- and more-oxidized fractions (LO-OOA and MO-OOA, respectively). These factors presented distinct seasonal patterns, associated with different atmospheric formation pathways. A pronounced increase in LO-OOA concentrations and contributions (50 %–66 %) was observed in summer, which may be mainly explained by secondary OA (SOA) formation processes involving biogenic gaseous precursors. Conversely, high concentrations and OA contributions (32 %–62 %) of MO-OOA during winter and spring seasons were partly associated with anthropogenic emissions and/or long-range transport from northeastern Europe. The contribution of the different OA factors as a function of OA mass loading highlighted the dominant roles of POA during pollution episodes in fall and winter and of SOA for highest springtime and summertime OA concentrations. Finally, long-term trend analyses indicated a decreasing feature (of about −175 ng m−3 yr−1) for MO-OOA, very limited or insignificant decreasing trends for primary anthropogenic carbonaceous aerosols (BBOA and HOA, along with the fossil-fuel and biomass-burning black carbon components) and no statistically significant trend for LO-OOA over the 6-year investigated period.
Unveiling the Impact of COVID-19 Vaccines: A Meta-Analysis of Survival Rates Among Patients in the United States Based on Vaccination Status

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a significant number of cases and deaths worldwide. Vaccination is the most effective preventive measure against the disease. This study aimed to assess the mortality rates of COVID-19 patients in the United States and the effectiveness of Pfizer (Pfizer, NY, USA), Moderna (Moderna, MA, USA), and Janssen (Johnson & Johnson, NJ, USA) vaccines in preventing mortality. A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA-2020) guidelines. Eligible studies reporting on the effectiveness of COVID-19 vaccines on patient outcomes were included. The search was performed in PubMed, Cochrane, and Google Scholar databases. The data were extracted, and risk ratios (RR) were calculated for mortality outcomes. The analysis was performed using Review Manager software, and bias assessments were conducted using the Joanna Briggs Institute (JBI) Meta-Analysis tools. A total of seven studies with 21,618,297 COVID-19 patients were included in the meta-analysis. The odds ratio (OR) for mortality among unvaccinated patients compared to vaccinated patients was 2.46 (95% CI: 1.71-3.53), indicating that unvaccinated patients were 2.46 times more likely to die from COVID-19. The findings of this study support the effectiveness of COVID-19 vaccination in reducing mortality among infected individuals. Unvaccinated patients had a significantly higher risk of mortality compared to vaccinated patients. Vaccination remains a crucial strategy to mitigate the severity of the disease and reduce mortality rates. Efforts should be made to address vaccine hesitancy and ensure widespread vaccine coverage.
Enhanced Removal of Phosphorus from Aqueous Solutions by Cation-Modified Hydrochar

In this study, cassava stem-derived hydrochar was modified with sodium hydroxide (NaOH) treatment, followed by loading of minerals, was used to prepare cation-modified hydrochars with enhanced phosphate removal ability. Cassava stems were converted to hydrochar by hydrothermal carbonization at 240 °C for 60 min, then it was soaked in 2 M NaOH for 3 h. The NaOH-treated hydrochars were then loaded with iron (Fe), magnesium (Mg) and calcium (Ca). The cassava stems and the derived hydrochars were analyzed for carbon, hydrogen, nitrogen and oxygen content, surface morphology and elemental compositions. Methylene Blue Numbers (MBN) measured surface area and porosity, and pH at the point of zero charge (pHpzc) was determined. Modification with Fe, Mg and Ca improved phosphate removal efficiency of the resulting hydrochars. Treatment of synthetic wastewater containing 50 mg P/L at pH 7 with the dosage of 2 g/L of the cation-modified hydrochars for 360 min showed that phosphate removal efficiency of these modified hydrochars were - Fe-modified 81 %, Mg-modified 66 % and Ca-modified 56 %. When the adsorbent dosage increased to 20 g/L, more than 98 % of phosphate was removed by the hydrochars modified with Fe, Ca and Mg. In the same conditions, phosphate removal efficiency was for the NaOH-treated hydrochars - 89 %, hydrochar derived from cassava steam - 69 % and the starting material - 59 %. The phosphate removal ability of these cation-modified hydrochars increased even when initial phosphorus concentration was increased to 100 mg P/L. This work demonstrated that an abundant agricultural residue, cassava stems, can be converted into effective phosphate adsorbents. HIGHLIGHTS Cassava stem were converted to hydrochar by aqueous carbonization at elevated temperature and pressure - hydrothermal carbonization (HTC) Sequential steps of alkali treatment and chemical modification, following HTC, were used to improve the phosphate removal ability of the cassava stem-derived hydrochar Loading of minerals (Fe, Mg and Ca) was a vital way to increase the adsorption of phosphates on hydrochar Phosphorus removal efficiency of Fe-loaded hydrochar was better than Mg- and Ca-loaded hydrochars Cation-modified hydrochars showed good phosphate removal ability over a wider concentration range GRAPHICAL ABSTRACT
A controlled, randomized nonblinded clinical trial to assess the ef ﬁ cacy of amphotericin B deoxycholate as compared to pentamidine for the treatment of antimony unresponsive visceral leishmaniasis cases in Bihar, India

Background: There is signiﬁ cant variation in Amphotericin B (AMB) efﬁ cacy and relapses in antimony unresponsive visceral leishmaniasis (VL) cases over a period of time (10–15 years). Keeping in mind the above mentioned view this study was undertaken with an objective to assess the magnitude of cure and relapse rates of AMB in the treatment of antimony unresponsive VL cases. Methods: In a controlled, randomized nonblinded clinical trial, we evaluated the cure and relapse rate of Amphotericin B deoxycholate as compared to pentamidine. A total of 82 sodium stibogluconate (SSG) unresponsive and parasitologically conﬁ rmed VL cases were included in this study and randomized into two groups, test (Amphotericin B) and control (Pentamidine). Both the groups were treated with recommended dosages (as per World Health Organization guidelines) of respective medicines. All the patients were followed up on 1st, 2nd, and 6th month after end of treatment. Results: Apparent cure rate in the Amphotericin B group was found to be 95% (39/41) compared with 83% (34/41) in the Pentamidine group, which shows signiﬁ cant statistical difference (p = 0.05). The ultimate cure rate was found 92% (38/41) in the Amphotericin B group compared to 73% (30/41) in the Pentamidine group, which shows a signiﬁ cant statistical difference (Yates corrected chi-square = 4.42, p = 0.04). Similarly, signiﬁ cant statistical difference was observed in the relapse rate of the Amphotericin group compared to the Pentamidine group (p = 0.03). Conclusions: AMB may still be the drug of choice in the management of resistant VL cases in Bihar, India. This is due to its consistent apparent cure rate (95%), low relapse rate (2.5%), and cost effectiveness compared with other available antileishmanial drugs. It is a safe drug even in case of pregnancy. Efforts should be taken to form a future strategy so that this drug and coming newer drugs do not meet a similar fate as has happened to SSG and pentamidine over a span of 10–15 years.
When do the effects of single‐session interventions persist? Testing the mindset + supportive context hypothesis in a longitudinal randomized trial

Abstract Background Single‐session interventions have the potential to address young people's mental health needs at scale, but their effects are heterogeneous. We tested whether the mindset + supportive context hypothesis could help explain when intervention effects persist or fade over time. The hypothesis posits that interventions are more effective in environments that support the intervention message. We tested this hypothesis using the synergistic mindsets intervention, a preventative treatment for stress‐related mental health symptoms that helps students appraise stress as a potential asset in the classroom (e.g., increasing oxygenated blood flow) rather than debilitating. In an introductory college course, we examined whether intervention‐consistent messages from instructors sustained changes in appraisals over time, as well as impacts on students' predisposition to try demanding academic tasks that could enhance learning. Methods We randomly assigned 1675 students in the course to receive the synergistic mindsets intervention (or a control activity) at the beginning of the semester, and subsequently, to receive intervention‐supportive messages from their instructor (or neutral messages) four times throughout the term. We collected weekly measures of students' appraisals of stress in the course and their predisposition to take on academic challenges. Trial‐registration: OSF.io; DOI: 10.17605/osf.io/fchyn. Results A conservative Bayesian analysis indicated that receiving both the intervention and supportive messages led to the greatest increases in positive stress appraisals (0.35 SD; 1.00 posterior probability) and challenge‐seeking predisposition (2.33 percentage points; 0.94 posterior probability), averaged over the course of the semester. In addition, intervention effects grew larger throughout the semester when complemented by supportive instructor messages, whereas without these messages, intervention effects shrank somewhat over time. Conclusions This study shows, for the first time, that supportive cues in local contexts can be the difference in whether a single‐session intervention's effects fade over time or persist and even amplify.

OXIDATIVE STRESS IN OVARIES OF FEMALE WISTAR RATS EXPOSED TO GEOPHAGIC CLAY (EKO)

The impacts of geophagy on reproductive health, especially the ovaries remain unexplored. The reproductive health of individuals (mostly pregnant women) may be impacted, by exposure to geophagic clay, as there is evidence to substantiate the presence of some contaminants in the studied geophagic clay. The ovary which is the site of production of female egg cells, in the female reproductive system can give useful information on the reproductive effects of this practice in exposed organisms. In this study, thirty-six (36) healthy adult female rats of the Wistar strain, were placed in six (6) groups, of six (6) animals each (A-F) and administered geophagic clay orally with gavage, for forty-two (42) days. Group (A) which served as the control group received feed and distilled water only. Groups (B-F) were administered (250, 500, 1000, 1500, and 2000) mg/kg bw geophagic clay dissolved in distilled water. Markers of oxidative stress were assessed. Histopathological examinations were also carried out on the ovaries. Comparison of the results obtained, by matching control group with the treatment groups, revealed that oxidative stress markers [superoxide dismutase (SOD) and malondialdehyde (MDA)] were elevated significantly (p < 0.05) mostly in the groups administered high doses (1000-2000 mg/kg bw) of geophagic clay. There was a marked depletion (p < 0.05) in reduced glutathione (GSH) level (2000 mg/kg bw). Histopathological examination of the ovaries revealed slight alterations in the anatomic features predominantly in the group administered the highest dose (2000 mg/kg bw). This finding infers possible toxicity in the ovaries especially when geophagic clay is consumed in high concentrations. This implies that geophagic clay may cause a redox imbalance in the ovary, altering female reproductive function, especially when consumed in high doses.
The Chattahoochee Chiefdoms

"This book provides a much needed summary of the excavations at several important but poorly documented mound sites and nicely synthesizes this data into a phase-by-phase history of chiefdom development in the Chattahoochee Valley. At the same time, the authors present a provocative model for the development and spread of Mississippian societies through the Southeast. " Along the banks of the lower Chattahoochee River, the remains of ancient settlements are abundant, including archaeological sites produced by Native Americans between 900 and 350 years ago, and marked by the presence of large earthen mounds. Like similar monuments elsewhere in the Southeastern United States, the lower Chattahoochee River mounds have long attracted the attention of travelers, antiquarians, and archaeologists. As objects from the mounds were unearthed, occasionally illustrated and discussed in print, attention became focused on the aesthetic qualities of the artifacts, the origins of the remains, and the possible relationship to the Creek Indians. Beginning in the 20th century, new concerns emerged as the developing science of archaeology was introduced to the region. As many of the sites became threatened or destroyed by reservoir construction, trained archaeologists initiated extensive excavations of the mounds. Although classification of artifacts and sites into a chronological progression of cultures was the main objective of this effort, a second concern, sometimes more latent than manifest, was the reconstruction of a past way of life. Archaeologists hoped to achieve a better understanding of the sociopolitical organization of the peoples who built the mounds and of how those organizations changed through time. Contemporary archaeologists, while in agreement on many aspects of the ancient cultures, debate the causes, forms, and degrees of sociopolitical complexity in the ancient Southeast. Do the mounds mark the capitals of political territories? If so, what was the scale and scope of these ancient "provinces"? What manner of society constructed the mound settlements? What was the sociopolitical organization of these long-dead populations? How can archaeologists answer such queries with the mute and sometimes ordinary materials with which they work: pottery, stone tools, organic residues, and the strata of remnant settlements, buildings, and mounds?
