LEVERAGING ACADEMIC AND VOCATIONAL PERFORMANCE THROUGH SELF-EFFICACY

The majority of research examining the impact of self-efficacy on performance across a variety of settings has provided evidence to validate the claim that agency beliefs facilitate human achievement. However, such inquiries have focused within a single domain of functioning. The present study explores the influence of agency beliefs on academic success and the counteraction of the lack of decisiveness in the case of career choice, also known as career indecision. The first part of the paper is conceptual and provides the reader with the theoretical background behind both constructs. The quantitative analysis supported the existence of a bi-directional relationship between the study variables. The last section of the paper is devoted to the qualitative investigation and discussion of the implications prompted by our examination and reveals several noteworthy conclusions: the inability of the participants to extend their agency beliefs from one domain of functioning to another domain without initial guidance and the lack of a clear vision of a future career path stemming from insufficient career counselling.
Investigation on photoluminescence emission of (reduced) graphene oxide paper

In order to contrastively investigate optical properties of graphene oxide (GO) and reduced graphene oxide (rGO) paper, GO is prepared by improved Hummer method and controlled reduced using hydration hydrazine to obtain good dispersive rGO in organic solvent. Finally, GO and rGO paper are obtained by vacuum filtration method. Samples morphology and optical properties are analyzed by scanning electron microscopy (SEM) images, Raman spectra, absorbance spectra and photoluminescence (PL) spectra. Results indicate that there are large numbers of localized states in both GO and rGO paper, and optical gaps of two samples are 0.62 eV. In PL spectra of GO paper, we observe three emission peaks at 565, 578 and 608 nm, respectively whose intensity decreases evidently after reduced, which is due to the decrease of oxide functionalized groups and expansion of sp2 clusters. PL emission will gradually decrease during GO are reduced.
Early effects of the Covid-19 on the Agricultural field: Evidence from two major commodities

: The Covid-19 pandemic has changed the dynamics of the overall economy, impacting many fields. Such a case is the agricultural sector, which was impacted in a significant manner. In this paper, we examine two most important commodities from the agricultural sector, namely the Oats and the Wheat, during the Covid-19 spread and the lockdown measures. Using relevant time series specifications, we establish a hypothesis regarding the effect of the Covid-19 pandemic on the values of these two commodities. Based on our findings, the values of the commodities were affected by the Covid-19 spread and moreover, the Covid-19 spread provides useful information for the predicting and forecasting of these values. Our findings are robust, since the out-of-sample forecasting accuracy of the alternative model employed, that explicitly incorporate the pandemic induced by the SARS-COV-2 virus, is superior to the baseline model.
Ion effect on the dynamics of water hydrogen bonding network: A theoretical and computational spectroscopy point of view

Understanding the elementary hydration dynamics of the ions and their couplings with the aqueous environments is important for researches in fields including energy, molecular biology, biomedical sciences, and chemical reactions. The concept of hydration shell is ubiquitously used to rationalize the differences of water behavior near the ions with respect to those in the bulk water. One intriguing issue, however, is to decide the spatial range of these hydration shells. Different experimental spectroscopic techniques such as the femtosecond infrared at high frequency and optical Kerr effect, dielectric relaxation, as well as terahertz measurements at low frequency often give controversial indications on this matter. As the optical transition observables provided by the spectroscopic measurements only indirectly reflect the real‐space structure and dynamics information, the theoretical modeling of these signals is often desired in order to reveal the underlying physics in each of these measurements, and to understand the aforementioned apparent controversy. In this review, we outline recent progresses in the theoretical modeling of water dynamics around the ions and ionic moieties and the related vibrational spectroscopy, especially on the femtosecond infrared related single molecular water reorientation and the low‐frequency vibrational spectra related collective water dynamics.
Prospective Comparison of Three Risk Score Models at Three Different Surgical Intensive Care Units

ABSTRACT Purpose: Although risk score models are of great value, their use is restricted because of the additional effort involved. The aim of this study was to compare three different score systems. Each of these requires a different degree of effort by the medical staff. One of the score systems is solely based on routine laboratory parameters. Data were collected on three different ICUs units, with each showing a large variety in patients’ health conditions. Methods: Prospective data of 588 surgical patients were collected by means of Acute Physiology and Chronic Health Evaluation II (APACHE II), Dense Laboratory Whole Blood Applied Risk Estimation (DELAWARE), and Simplified Acute Physiology Score II (SAPS II) score systems. These patients were admitted to three different intensive care units over a period of 12 months. On the day of admission, predicted hospital survival and mortality were evaluated. Results: With a cutoff value of 0.6, the sensitivity of the APACHE II, DELAWARE, and SAPS II was at 0.19, 0.24, and 0.21; the specificity was at 0.98, 0.92, and 0.98; and the correct classification rate at 0.86, 0.83, and 0.86. The r2 value was 0.35 for the APACHE II, 0.12 for the DELAWARE, and 0.21 for the SAPS II. The hospital mortality rate was overestimated in all three score systems. Conclusions: The results of this first multicenter study comparing three risk score systems indicate that it is possible to establish a general risk score for surgical intensive care patients on admission date. Such a risk score is solely based on quality-controlled, low-cost routine laboratory parameters.
The comparison of survival between active surveillance or watchful waiting and focal laser ablation in patients with low-risk prostate cancer

Prostate cancer (PCa) is the second-most common cancer among men. Both active surveillance or watchful waiting (AS/WW) and focal laser ablation (FLA) can avoid the complications caused by radical treatment. How to make the choice between these options in clinical practice needs further study. Therefore, this study aims to compare and analyze their effects based on overall survival (OS) and cancer-specific survival (CSS) to obtain better long-term benefits. We included patients with low-risk PCa from the Surveillance Epidemiology and End Results database of 2010–2016. Multivariate Cox proportional hazard analyses were conducted for OS and CSS in the two groups. To eliminate bias, this study applied a series of sensitivity analyses. Moreover, Kaplan–Meier curves were plotted to obtain survival status. A total of 18 841 patients with low-risk PCa were included, with a median of 36-month follow-up. According to the multivariate Cox proportional hazard regression, the FLA group presented inferior survival benefits in OS than the AS/WW group (hazard ratio [HR]: 2.13, 95% confidence interval [CI]: 1.37–3.33, P < 0.05). After adjusting for confounders, the result persisted (HR: 1.69, 95% CI: 1.02–2.81, P < 0.05). According to the results of the sensitivity analysis, the inverse probability of the treatment weighing model indicated the same result in OS. In conclusion, AS/WW and FLA have the advantage of fewer side effects and the benefit of avoiding overtreatment compared with standard treatment. Our study suggested that AS/WW provides more survival benefits for patients with low-risk PCa. More relevant researches and data will be needed for further clarity.
Multi-binding biotinylated iron oxide nanoparticles as a promising versatile material for magnetic biomedical applications

The tetrameric streptavidin and avidin both have four sites that can specifically bind with biotin. Taking advantage of this high affinity binding, it is possible to realise multi-binding of biotinylated nanoparticles to avidin or streptavidin molecules. The iron oxide nanoparticles (IONPs) have been actively investigated in biomedical applications. In this work, biotinylated IONPs (biotin-IONPs) with around 10.5 nm magnetic core size were synthesised. They exhibited long-term hydrophilic stability, and the activity of the biotin content was verified by avidin-horseradish peroxidase induced chromogenic experiment. These biotin-IONPs were then studied as magnetic labels in substrate-based and substrate-free magnetic bio-labelling scheme of alpha-fetoprotein. The multi-binding ability of these biotin-IONPs with streptavidin functionalised detection antibody (streptavidin-detection antibody) was proved both on microplate well surfaces and in solution. Consequently, biotin-IONPs are promising magnetic label materials for the improvement of magnetic biodetection. In addition, the avidin-induced biotin-IONP assemblies were produced in MilliQ water solution and in water-in-oil microemulsion system. In summary, based on their multi-binding nature, the biotin-IONPs can be considered as a versatile material to improve the sensitivity of magnetic biodetection and to be further built into assemblies for future biomedical applications such as magnetic resonance imaging and target drug delivery.

Abstract The purpose of this paper is to showcase initial considerations taken in the process of Product-Service Systems (PSS) development in the capital goods manufacturing companies. The focus is on the identification of both generic drivers and barriers that typically present themselves. Drivers and barriers are classified and compared, with respect to developed dimensions that aim to encompass different aspects relevant to PSS development. The classification presented in this paper has promise when researching how to support companies that aspire to develop and implement PSS, both to invigorate internal motivation for change and to understand crucial obstacles that might arise in the process. Furthermore, a chain of discovered motives and challenges for PSS is discussed, in an attempt to relate and connect the general manufacturing industry to the capital goods manufacturing industry.
Synthesis, characterization, and voltammetric hydrogen peroxide sensing on novel monometallic (Ag, Co/MWCNT) and bimetallic (AgCo/MWCNT) alloy nanoparticles

ABSTRACT Multiwall carbon nanotube supported (MWCNT) Ag, Co, and Ag-Co alloy nanocatalysts were synthesized at varying metal loadings by borohydride reduction methods without stabilizers to obtain enhanced hydrogen peroxide sensitivity. The resulting materials were characterized employing Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). For electrochemical measurements carried out cyclic voltammetry (CV) and differential pulse voltammetry (DPV), glassy carbon electrode (GCE) was modified with Ag/MWCNT, Co/MWCNT, and Ag-Co/MWCNT alloy nanoparticles. Ag-Co/MWCNT/GCE exhibited the highest performance toward electrochemical oxidation of H2O2 in 0.1 M phosphate buffered solution (PBS). Furthermore, the sensitivity and the limit of detection values for Ag-Co/MWCNT/GCE were obtained as 57.14 µA cm−2 mM−1and 0.74 µM, respectively. However, the sensitivity values for Ag/MWCNT/GCE, and Co/MWCNT/GCE are 41.66 and 13.88 µA cm−2 mM−1, respectively. The LOD values were predicted as 1.84 µM for Ag/MWCNT/GCE and 3.3 µM for Co/MWCNT/GCE. In addition, the interference experiment indicated that the Ag-Co/MWCNT alloy nanoparticles have good selectivity toward H2O2.
Plasma p tau 181 levels is associated with white matter microstructural changes in across the Alzheimer’s disease stages

Alzheimer’s Disease (AD) is characterized by cognitive impairments and memory difficulties, which hinder daily activities and lead to personal and behavioral problems. In recent years, blood-based biomarkers like plasma phosphorylated tau protein at threonine 181 (p tau 181) emerged as new tools and showed sufficient power in detecting AD patients from healthy people. Here we investigate the correlation between p tau 181 and white matter microstructural changes in AD. We add 41 patients diagnosed with Alzheimer’s, 119 patients with mild cognitive impairments and 43 healthy controls with baseline plasma p tau 181 level and DTI values for each region of interest from the ADNI database. The analysis revealed that the plasma level of p tau 181 could predict changes of MD (Mean Diffusivity), RD (Radial Diffusivity), DA (Axial Diffusivity) and FA (Fractional Anisotropy) parameters in widespread regions and there is a significant association between white matter pathway alteration in different regions and p tau 181 plasma measurements within each group. In conclusion, our findings showed that plasma p tau 181 levels are associated with cellular and molecular changes in AD, which enhance the biomarkers for diagnostic procedures and support the application of plasma p tau 181 as a biomarker for white matter changes and neurodegeneration. Longitudinal studies are also necessary for proving the efficacy of these biomarkers and predicting the role in structural changes.
Seasonal Breeding Leads to Changes for Gut Microbiota Diversity in the Wild Ground Squirrel (Spermophilus Dauricus)

Background: Seasonal breeding is a normal phenomenon that animals adapt to natural selection and reproduce only in specific seasons. With the gradual popularization of Next-generation sequencing (NGS), large studies have shown that seasonal breeding has been affected by gut microbiota. Consequently, the purpose of this study is to explore the effect of seasonal breeding on the gut microbiota of wild ground squirrel (Spermophilus dauricus). We used 16S rRNA gene sequencing technology to sequence the gut microbiota of the wild ground squirrel in the breeding season and non-breeding season. We also predicted the function of gut microbiota by bioinformatic software.Results: The results showed that the main components of gut microbiota in all samples consisted of Firmicutes (61.8%), Bacteroidetes (32.4%), and Proteobacteria (3.7%). Microbial community composition analyses revealed significant differences between these two groups. At the genus level, Alistipes, Mycoplasma, Anaerotruncus, and Odoribacter were up-regulated in the non-breeding season, while Blautia and Streptococcus spp. were up-regulated in the breeding season. The result of function prediction suggested that the relative abundance of functional categories related to lipid metabolism, carbohydrate metabolism, and nucleotide metabolism was higher in the breeding season. The expression of transcription, energy metabolism, and signal transduction was enriched in the non-breeding season. Conclusions: Overall, the results of this study emphasized the significant effects of seasonal breeding on gut microbiota community composition of the wild ground squirrel and laid a foundation for further study of gut microbiota on seasonal breeding in the future.
A Right or Privilege: Provision of Spiritual Care to Patients within Health Care Setting in Northern Ghana

Spiritual care recognizes and responds to the needs of the human spirit in the face of ill health or sadness. These include but not limited to the need for a meaning of existence, self-worth, express oneself, faith, support and perhaps for rites, prayer, sacrament or simply for a sensitive listener. The study assesses the role of health care providers in providing the emotional and spiritual needs of the patients in adult wards. The study adopted the mix method approach. The study reveals a mean value of 4.04 meaning nurses regularly listen actively to patients talk about their religious/spiritual beliefs, strengths, and beliefs about God. Data from the study further reveal that nurses regularly give patients or caretakers the opportunity to talk about God and support coming from God. The study further revealed the following as the barrier to providing emotional/spiritual care to patients admitted to the adult ward of the hospital; Because of different beliefs of the staffs and the patients, most of the patients do not believe in superstition, lack of communication skills in giving this care, Lack of pastors and imams in the hospitals, multiple beliefs of the patients. Thus, it is recommended that policymakers like the government and the Ghana health service should be encouraged to capture the spiritual needs of patients in the management protocols. The Tamale central hospital should employ people who are well versed in spiritual health care in the hospital. The hospital should employ an Imam and a Pastor to complement the nurse’s role in taking care of the spiritual needs of the patient.

Phase-Controlled Colloidal Syntheses of Iron Sulfide Nanocrystals via Sulfur Precursor Reactivity and Direct Pyrite Precipitation

In the colloidal synthesis of iron sulfides, a series of dialkyl disulfides, alkyl thiols, and dialkyl disulfides (allyl, benzyl, tert-butyl, and phenyl) were employed as sulfur sources. Their reactivity was found to tune the phase between pyrite (FeS2), greigite (Fe3S4), and pyrrhotite (Fe7S8). DFT was used to show that sulfur-rich phases were favored when the C–S bond strength was low in the organosulfurs, yet temperature dependent studies and other observations indicated the reasons for phase selectivity were more nuanced; the different precursors decomposed through different reaction mechanisms, some involving the oleylamine solvent. The formation of pyrite from diallyl disulfide was carefully studied as it was the only precursor to yield FeS2. Raman spectroscopy indicated that FeS2 forms directly without an FeS intermediate, unlike most synthetic procedures to pyrite. Diallyl disulfide releases persulfide (S–S)2– due to the lower C–S bond strength relative to the S–S bond strength, as well as facile .

Preparation of Phthalocyanine Immobilized Bacterial Cellulose Nanocomposites for Decoloration of Dye Wastewater: Key Role of Spacers

: We report the preparation of a series of spacer-incorporated, tetra-amino cobalt (II) phthalocyanine (CoPc)-immobilized bacterial cellulose (BC) functional nanocomposites (CoPc@s-BC). Four kinds of ﬂexible spacers with different lengths—diethylenetriamine (DT), triethylenetetramine (TT), tetraethylenepentamine (TP) and pentaethylenehexamine (PH)—were covalently attached onto pre-oxidized BC for the synthesis of the spacer-attached BC, and the attached spacers’ contents were carefully quantiﬁed. Using glutaraldehyde as a cross-linker, the CoPc catalyst was covalently immobilized onto the spacer-attached BC, and the immobilization steps were optimized by monitoring both the residual spacer contents and the resulting immobilized CoPc. All of the functionalization processes were characterized and conﬁrmed by X-ray photoelectron spectroscopy (XPS). The series of spacer-incorporated, CoPc-immobilized BC nanocomposites, CoPc@s-BC, were used for the decoloration of dye wastewater. Both the adsorption capacity and adsorption rate were increased after the incorporation of spacers. When H 2 O 2 was employed as an oxidant, dye molecules were catalytically oxidized with these nanocomposites. Electron paramagnetic resonance (EPR) spin-trapping results showed that the highly reactive hydroxyl radical ( · OH) was involved in the catalytic oxidation process. The spacer length had a direct effect on the catalytic efﬁciency of CoPc@s-BC—the decoloration rate for CoPc@TP-BC was as high as 41 µ mol · min − 1 · g − 1 , which was more than 50% higher than that without spacer.
