An Experimental Study on the Buffering Mechanism of College Students' Entrepreneurial Failure from the Perspective of Customer Loyalty

Since the “mass entrepreneurship and innovation” was put forward, the innovation and entrepreneurship activities of college students have gradually become the new focus of social development. However, problems such as insufficient practical experience also make college students encounter many difficulties in innovation and entrepreneurship. Especially under the attack of the epidemic this year, uncertain and unstable factors are increasing, the problem of entrepreneurial failure has attracted great attention from all sectors of society. Th research results related to “mass entrepreneurship and innovation” mainly focus on the education model of “mass entrepreneurship and innovation” in colleges and universities and the cultivation of “mass entrepreneurship and innovation” ability of college students. There are few in-depth demonstrations from the perspective of customer loyalty of “mass entrepreneurship and innovation” products. Based on this, the project team focused on the customer loyalty of college students' mass entrepreneurship and innovation products, used experiments and questionnaires as the main research methods, and collected valid data from 505 college students online. The data analysis adopted descriptive statistics, correlation analysis, partial correlation analysis, crosstab analysis, correspondence analysis, independent sample T test, hierarchical regression analysis and other methods to gradually model, and obtain the following results: “perceived quality”, “perceived value”, and the mediating effects of “brand image” have all been tested, and the situational moderation effect is relatively obvious. In both scenarios, the brand image, perceived value, and perceived quality all had a positive impact on loyalty, but the coefficient changes before and after the situation changes. However, the influence of customer expectations on perceived quality shifted from positive to negative. The correct positioning of the brand image and the high experience of perceived value could well stabilize customer loyalty in risk situations. Finally, the project team put forward countermeasures based on the above conclusions on the three levels of the government, entrepreneurship and innovation teams and schools.
Preliminary Evaluation of Speech-to-Text Query Application for Parts Database

— To ensure the safety and security of workplaces and homes, parts replacement of mechanical/electric/electronic devices is inevitable, because they will gradually break down. Users have to search for the appropriate part numbers from a parts database to order and replace the parts. In many cases, users make phone calls to the support center of the vendors instead of searching by themselves, which can be inconvenient for the support center staff. In this paper, to reduce the number of phone calls to support centers, we propose a prototype of an automatic part number answering system from natural language. This system consists of open-source speech-to-text conversion and Structured Query Language (SQL) generation from the natural language. Preliminary evaluation results show that 83% of the voice questions returned the correct part numbers. In addition, the search with our system was executed an average of 3.86 times faster than with the conventional manual keyword search.
Rough-Sea-Horizon-Line Detection using a Novel Color Clustering and Least Squares Regression Method

: Sea horizon line (SHL) detection is the first step in maritime image processing. It is aimed at object detection, navigation of autonomous aerial and sea surface vehicles, and distance estimation. Many methods have been proposed to detect SHL, however, their focus remains on SHL detection in calm sea conditions. For this reason, this study is designed to fill this gap and investigate an efficient method to detect a sea horizon line under rough sea conditions. A novel color clustering and least-squares regression-based method is proposed to solve the issue. Minimizing computational cost, our method identifies the candidate region of interest (CROI) from grayscale image ROIs by analyzing the modality of its pixel intensity histogram. It then applies k -mean clustering to highlight potential sea-sky regions. The regional boundary pixel coordinates are used to construct a horizon line by applying the least-squares regression method. The results of the proposed method were compared to the Canny Edge and Hough Transform (CEHT) method. The gale state sea images were used to test the efficiency of both methods, correctly detecting the starting and ending coordinates of a horizon line and its slope. The results highlight the superiority of the proposed method over the CEHT method. On average, the proposed method identified the horizon line within one degree of error as opposed to CEHT method with the average of five degrees. In half of the images, the error in detecting the horizon starting and ending coordinates for the proposed method was within five or fewer pixels. The overall results show the superiority of the proposed method over the CEHT method in rough sea conditions. The novelty of this study is two-fold. Firstly, it is a pioneering study that proposes a novel method to detect SHL under rough sea conditions. Secondly, the proposed method yielded superior SHL detection results compared to its peers.
Post-operative pain after 38% silver diamine fluoride application in primary molars with deep caries versus interim restorative therapy: A randomized pilot study

Aim: To compare the post-operative pain after application of Silver Diamine Fluoride (SDF) 38% in cavitated primary molars, in relation to Interim Restorative Therapy (IRT). Design: The study was performed on 20 carious primary molars in children aged 4-6 years attending the clinic in Pediatric Dentistry and Dental Public Health Department- Faculty of Dentistry -Cairo University. Partial excavation of caries on the walls of the cavity was performed then in group (A) SDF was applied in two visits with one-week interval, and finally Resin Modified Glass Ionomer Restoration (RMGI) was applied to the cavity. While, in group (B) Resin Modified Glass Ionomer restoration was applied immediately after partial caries excavation. Clinical and radiographic examinations were performed at three and six month’s follow-up periods for both groups.Results: In both groups, 100% of patients had no complications at three and six months follow up periods; except for 10% of patients experienced failure of restoration at three months in group B. The results showed insignificant differences between groups regarding clinical and radiographic outcomes at both three and six months. Conclusions: Silver Diamine Fluoride and Interim Restorative Therapy were clinically and radiographically successful when used in primary molars with cavitated dentin carious lesions.
Smartphone addiction, selected psychological status and clinical variables among undergraduates in a Nigerian population

Background. The use of smartphones in our current digital society has resulted in the development of musculoskeletal and emotional symptoms among undergraduates. Objectives. To determine the correlations among smartphone addiction, selected psychological status and clinical variables among undergraduates in the College of Medicine, University of Lagos, Nigeria. Methods. A cross-sectional survey was conducted among 837 undergraduates (500 females, 337 males). Questionnaires comprising a smartphone addiction scale, depression, stress and anxiety scale, neck disability index and shoulder pain disability index were used to collect self-report measures. Assessment of selected anthropometric variables (weight, height and body mass index (BMI)) was done. Pearson’s correlation coefficient and Spearman’s ρ were used to determine the correlation between variables at an α value of p <0.05. Results. The outcome of this study revealed that more than half, 447 (53.4%), of the undergraduates were addicted to smartphone use. Eighty (9.6%) participants had severe depression, 155 (18.5%) had severe anxiety while 59 (7%) were severely stressed. It was observed that there was a significant relationship ( p <0.05) but a weak correlation between smartphone addiction, psychological status, pain-related disability of neck and shoulder, BMI and weight. Conclusion. Smartphone addiction is prevalent among undergraduates, and is correlated with their psychological status, selected anthropometric variables and pain-related disability of the neck and shoulder. It is recommended that undergraduates be enlightened on the impact of smartphone addiction on psychological health and the musculoskeletal system.
Dielectric Studies of PEO-based Polymer Electrolytes Doped with LiTFSI Salt and EMIMTFSI Ionic Liquid

In this work, poly (ethylene oxide) (PEO) is doped with Lithium bis (trifluoromethanesulfonyl) imide (LiTFSI) salt and 1-Ethyl-3-methylimidazolium bis (trifluromethanesulfonyl) imide (EMIm-TFSI) ionic liquid, a plasticiser, for preparation of PEO-LiTFSI-EMImTFSI plasticised polymer electrolyte (PPE) system. Impedance spectroscopy is used to analyse the dependence of dielectric behaviour of the films on frequency and temperature. It is performed in the temperature range between 303K to 343K for frequencies between 50 Hz to 1 MHz. The cationic transport in the films may be explained from the dielectric constant, ԑr and dielectric loss, ԑi where they are found to increase with temperature at lower frequency and decrease at higher frequency, showing that the electrodes were being polarized. Both real parts, Mr and imaginary part, Mi of the modulus showed an increase at high frequency that indicates the spread of conductivity relaxation. The highest temperature (343K) achieved the lowest relaxation time, τ due to increase in number of ions and increase in mobility of ions in the polymer system indicating that conductivity in this system is thermally activated.
Synthesis and Characterization of Photocatalytic Activity of Hematite/ Cobalt Oxide/ Graphite Nanocomposites

In this study, at first step nanopowder particles of α-Fe2O3 (Hematite) and Co3O4 were synthesized separately thorough simple chemical method from an aqueous solution of iron (III) nitrate nonahydrate (Fe(NO3)3.9H2O) and cobalt (II) nitrate hexahydrate (Co(NO3)2.6H2O) as precursors. After that, three composites from synthesized nanopowders of Fe2O3 with 8, 16 and 24 wt. % of Co3O4 were prepared. Graphite nanopowder was added to one composition of samples in weight percentages of 1.17 and 2.35. The composition and morphology of the composites were investigated by XRD and FE-SEM, respectively. FE-SEM analysis showed that the morphology of the powders and composites were all spherical in nanoscale. The photocatalytic activity of the composites was examined by measuring the photo-degradation of the aqueous solution of methylene blue under simulated solar light. To determine the photo catalytic activity, the degradation of methylene blue (MB) in the absence of light (dark test) was taken as well. Results showed that addition of Co3O4 to Fe2O3 decrease the activity of photo-catalytic process while nano-graphite enhanced photo-catalytic process by upward of ~2 % with respect to the composite without graphite nanoparticles. Stoichiometric calculations showed that the amount of hydrogen produced by water by the composite of Fe2O3-16% Co3O4- 2.35% Graphite nanoparticles was 27 μmol H2/h.g under solar light irradiation.
Monocopper Active Site for Partial Methane Oxidation in Cu-Exchanged 8MR Zeolites

Direct conversion of methane to methanol using oxygen is experiencing renewed interest owing to the availability of new natural gas resources. Copper-exchanged zeolites such as mordenite and ZSM-5 have shown encouraging results, and di- and tri-copper species have been suggested as active sites. Recently, small eight-membered ring (8MR) zeolites including SSZ-13, -16, and -39 have been shown to be active for methane oxidation, but the active sites and reaction mechanisms in these 8MR zeolites are not known. In this work, we use density functional theory (DFT) calculations to systematically evaluate monocopper species as active sites for the partial methane oxidation reaction in Cu-exchanged SSZ-13. On the basis of kinetic and thermodynamic arguments, we suggest that [CuIIOH]+ species in the 8MR are responsible for the experimentally observed activity. Our results successfully explain the available spectroscopic data and experimental observations including (i) the necessity of water for methanol extraction.
Subjective Norms and Academic Dishonesty : A Decision Tree Algorithm Analysis

Academic dishonesty becomes an exciting phenomenon to be examined. This research aimed to examine the effect of subjective norms on academic dishonesty. Data were collected from 426 accounting students from public and private universities in Yogyakarta, Indonesia. The data were analyzed with the J48 algorithm decision tree. The interest that happened in the low subjective norms node was divided into public universities and private universities. Based on the decision of tree visualization, male students with the more extended length of study in public universities tended to have lower subjective norms but higher academic dishonesty than their counterparts. The results were discussed, and recommendations were also provided to several relevant parties.
Targeted search of hypoglycemic agents among N-substituted isoindoline-1,3-diones and its analogues

It is known, that increasing of glucose level in the blood is an important factor at the risk of vascular complications in diabetes mellitus type 2 development. Taking this into account, short-acting priming regulators of glycemia (meglitinides) are designed, such as tableted sugar-reducing drugs with short acting insulin secretion stimulation. They are characterized by a slight decrease of glycohemoglobin content, the risk of body weight gain and decrease of efficacy during long-term usage despite their effectiveness. The solution of this problem can be as following: the creation of more effective drugs, which would contain known antidiabetic “pharmacophore” fragments able to provide a long-term hypoglycemic effect and having a polyvectoral mechanism of activity and effect both on symptoms of the disease and on disease etiology.
Methane Recovery and Microbial Community Analysis of a High Solid Thermophilic Co-digestion of Sewage Sludge and Waste Fried Tofu

A continuous high solid co-digestion experiment of dewatered sludge from an oxidation ditch process and waste fried tofu was conducted at 55°C in the present study. Sludge retention time was 10 days, and the mixing ratio of sludge, dry and raw fried tofu was 1:0.39:0.06 (dry weight basis). Total solids (TS) of substrate was increased gradually (30, 50, 70, 100 g/L) in the sludge digestion, while TS was increased and then decreased in the co-digestion (43.5, 72.5, 101.5, 72.5 g/L). In the sludge digestion, performance was stable when the TS was below 70 g/L (organic loading rate (OLR) was 5.9 kg-volatile solids (VS)/(m 3 ·d)), and methane yields of sludge were 0.05–0.08 L/g-TS. In the co-digestion, biogas production significantly increased by the fried tofu addition. When total TS was increased to 101.5 g/L (OLR 8.8 kg-VS/(m 3 ·d)), accumulation of ammonia and volatile fatty acid was observed, inhibition was indicated. Methane fermentation failed to recover when the TS was decreased to 72.5 g/L (OLR 6.3 kg-VS/(m 3 ·d)). Results of the denaturing gradient gel electrophoresis analysis of the microbial community revealed a significant difference in the bacterial community with the fried tofu addition, while no major difference in the archaeal community was recognized.
GINN: Fast GPU-TEE Based Integrity for Neural Network Training

Machine learning models based on Deep Neural Networks (DNNs) are increasingly deployed in a wide variety of applications, ranging from self-driving cars to COVID-19 diagnosis. To support the computational power necessary to train a DNN, cloud environments with dedicated Graphical Processing Unit (GPU) hardware support have emerged as critical infrastructure. However, there are many integrity challenges associated with outsourcing the computation to use GPU power, due to its inherent lack of safeguards to ensure computational integrity. Various approaches have been developed to address these challenges, building on trusted execution environments (TEE). Yet, no existing approach scales up to support realistic integrity-preserving DNN model training for heavy workloads (e.g., deep architectures and millions of training examples) without sustaining a significant performance hit. To mitigate the running time difference between pure TEE (i.e., full integrity) and pure GPU (i.e., no integrity) , we combine random verification of selected computation steps with systematic adjustments of DNN hyperparameters (e.g., a narrow gradient clipping range), which limits the attacker's ability to shift the model parameters arbitrarily. Experimental analysis shows that the new approach can achieve a 2X to 20X performance improvement over a pure TEE-based solution while guaranteeing an extremely high probability of integrity (e.g., 0.999) with respect to state-of-the-art DNN backdoor attacks.
Catechin Contents, Antioxidant and Antibacterial Activities of Different Types of Indonesian Tea (Camellia sinensis)

Tea is one of the most popular beverages in the world. Produced from Camellia sinensis leaves, tea has been studied to provide health benefits due to the content of important metabolites. This study aimed to investigate the catechin contents, antioxidant, and antibacterial activities of Indonesian tea varieties, namely green tea, black tea, and white tea. Tea infusion was prepared by extracting 1 g of each sample into 10 mL of distilled water and incubated at 80 ° C for 60 min. The catechin and epigallocatechin gallate (EGCG) contents of tea extracts were determined using high-performance liquid chromatography (HPLC). Antioxidant activity was measured using the free radical method with 2,2-diphenyl-1-pycrylhidrazyl (DPPH), while antimicrobial activity was assesed using paper disc diffusion assay. The results indicated that green tea had the highest contents of catechin (646 ± 17.14 mg/L) and EGCG (997.8 ± 36.72 mg/L), and antioxidant activity with IC 50 of 5.65 µg/mL. Furthermore, green tea and white tea extracts showed inhibitory activity against Gram-positive bacteria such as Micrococcus luteus, Bacillus subtilis , and Staphylococcus aureus whereas black tea had no activity against all bacterial strains tested. Generally, we concluded that white tea and green tea contributed to the higher content of catechins and exhibited strong antioxidant and antibacterial properties.
Running Head: SOCIAL INTERACTION IN BORDERLINE PERSONALITY Social Interaction Patterns, Therapist Responsiveness and Outcome in Treatments for Borderline Personality Disorder

Objectives: Inflexible social interaction patterns are defining features of borderline personality disorder (BPD). Specific beliefs about the self and others may be activated across interaction situations, often leading to instable relationships. It may be pivotal to address these difficulties in early treatment phases, through appropriate therapist responsiveness, which means an adaptation of therapist’s activity to their client’s behaviors using emerging information in the process (Stiles, 2009). Design: In this process-outcome study, responsiveness is operationalized by the motive-oriented therapeutic relationship (Caspar, 2007), based on the Plan analysis case formulation. The present study assesses the interplay between social interaction problems and therapist responsiveness, explaining symptoms at discharge and the therapeutic alliance. Method: In total, N = 50 clients with BPD entered the study, and standard and responsive treatments were compared. Social interaction patterns were assessed by the newly developed borderline interaction patterns scale (BIPS), applied to recorded material of three sessions per therapy. Outcome was measured by general symptoms (OQ-45), borderline symptoms (BSL-23), interpersonal problems (IIP), as well as the therapeutic alliance (WAI). Results: Results suggest that in standard treatment, social interaction patterns are neither related to outcome nor the therapeutic alliance. In responsive treatment, more activation of social interaction patterns predicted better outcome on IIP and lower therapist ratings of the alliance. Conclusions: The conclusions seem promising for specific effectiveness of responsive treatments in particular in the interpersonal problem area of BPD. Identifying social interaction patterns early in treatment may be a crucial pathway to change for BPD. Practitioner Points: • Responsive therapy activating social interaction patterns may be crucial for better outcome. • Future research should focus on mechanisms of change in early treatment phases for BPD. SOCIAL INTERACTION IN BORDERLINE PERSONALITY DISORDER 3 • New scale for assessing social interaction patterns specific to borderline personality disorder.
A Salamander tale: Relative abundance, morphometrics and microhabitat of the critically endangered Mexican salamander Pseudoeurycea robertsi (Taylor, 1939)

Roberts’ False Brook Salamander (Pseudoeurycea robertsi) is a critically endangered plethodontid salamander, endemic to the Nevado de Toluca Volcano (NTV), Mexico. Little is known about the biology and ecology of this species, including its microhabitats. Thus, this study aimed to collect basic information about P. robertsi. We sampled fourteen forested sites in the NTV; to corroborate the correct identification of the species we used genetic data, we assessed the variation in head morphometric measurements and dorsal colouration patterns amongst localities and the microhabitat features associated with P. robertsi presence. Of the four potential salamander species, P. robertsi was the most abundant (89.80%) and widely distributed (approximately within 130 km2) salamander in the NTV. We did not find significant variations in morphometry; however, we found significant differences in dorsal patterns between populations (in the number and size of segments of the dorsal stripe). The average total length for 185 adults was 89.15 mm (38.7–117.9 mm); we found seven patterns of dorsal stripe. We found 98% of P. robertsi individuals under the bark of fallen logs in Abies religiosa and A. religiosa-Pinus sp. forests, with a higher number of detected salamanders in naturally-fallen logs than in cut logs (34% vs. 10%). Thus, keeping well-preserved A. religiosa forests and retaining fallen logs is essential to P. robertsi conservation.
INVESTIGATING LINKAGES OF PERFORMANCE APPRAISAL, EMPLOYEE PROMOTION AND JOB SATISFACTION WITH EMPLOYEE PERFORMANCE IN BANKING SECTOR OF PAKISTAN

This research investigated the association between performance appraisal, employee promotion job satisfaction with employee performance in the banking sector of Pakistan. The SEM analysis approach was utilized in Smart PLs on 280 samples of bank officers. It has been revealed by the results that performance appraisal has a constructive relationship with employee promotion, satisfaction, and performance. Moreover, rewards and appreciations are not based on the number of tasks or workload. Additionally, research explicated and expressed the worthiness of human resource practices from the perspective of the private banking sector of Pakistan. The research implications suggest that authorities of private banks must pay significant attention to recognition and reward practices as workers expecting rewards accordingly to their efforts.
