The Effect of Electronic Service Quality, Customer Shopping Experience, And Trust on Repurchase with Customer Involvement as Mediation on Shopee Customers in Banda Aceh
Authors: Fitria Iqa , Adam Muhammad , Hafasnuddin
Published: August 2023

This research aims to examine the electronic service quality, customer shopping experience, and trust role in repurchase with customer involvement as mediation on Shopee customers in Banda Aceh City. In this study, the population was all the people of Banda Aceh City who have made purchases at the Shopee Marketplace. This study used non-probability sampling - Quota Sampling as a method of sampling the respondents who have made purchases on Shopee ecommerce. The number of samples is 150. Data were collected by distributing questionnaires and were tested using SPPS, AMOS, and Sobel calculator as statistical tools. The results prove that according to the perspective of Shopee customers in Banda Aceh, Electronic Service Quality, Customer Experience, Trust, Customer Involvement, and Repurchase have been Good; Electronic Service Quality significantly affects Customer Involvement; Customer Shopping Experience significantly affects Customer Involvement; Trust significantly affects Customer Involvement; Electronic Service Quality significantly affects Repurchase; Customer Shopping Experience does not significantly affect Repurchase, Trust does not significantly affect Repurchase, Customer Involvement significantly affects Repurchase, Electronic Service Quality significantly affects Repurchase Through Customer Involvement, Customer Shopping Experience does not significantly affect Repurchase through Customer Involvement, and Trust significantly affects Repurchase through Customer Involvement. The findings also prove that customer involvement serves as a partial mediator for the Electronic Service Quality role in Repurchase and as a full mediator for the Trust role in Repurchase. So it is evident that the model of increasing Repurchases for Shopee customers in Banda Aceh is a function of improving its Shopee Electronic Service Quality, increasing customer Trust, and increasing customer involvement.

Deviants violating higher-order auditory regularities can become predictive and facilitate behaviour
Authors: Coy Nina , Bendixen Alexandra , Grimm Sabine , Roeber Urte , Schröger Erich
Published: August 2023

The human auditory system is believed to represent regularities inherent in auditory information in internal models. Sounds not matching the standard regularity (deviants) elicit prediction error, alerting the system to information not explainable within currently active models. Here, we examine the widely neglected characteristic of deviants bearing predictive information themselves. In a modified version of the oddball paradigm, using higher-order regularities, we set up different expectations regarding the sound following a deviant. Higher-order regularities were defined by the relation of pitch within tone pairs (rather than absolute pitch of individual tones). In a deviant detection task participants listened to oddball sequences including two deviant types following diametrically opposed rules: one occurred mostly in succession (high repetition probability) and the other mostly in isolation (low repetition probability). Participants in Experiment 1 were not informed (naïve), whereas in Experiment 2 they were made aware of the repetition rules. Response times significantly decreased from first to second deviant when repetition probability was high—albeit more in the presence of explicit rule knowledge. There was no evidence of a facilitation effect when repetition probability was low. Significantly more false alarms occurred in response to standards following high compared with low repetition probability deviants, but only in participants aware of the repetition rules. These findings provide evidence that not only deviants violating lower- but also higher-order regularities can inform predictions about auditory events. More generally, they confirm the utility of this new paradigm to gather further insights into the predictive properties of the human brain.

Based on the materials of research in 2015 and 2018, data on the spatial distribution and biological state of crabs in one of the new fishing areas for the Russian Federation are presented - subregion 61.52 Central part of the Sea of Okhotsk. In the area studied, the following commercial crab species were recorded in crab trap catches: Lithodes aequispinus, L. couesi, Paralomis multispina, P. verrilli, Chionoecetes opilio and Ch. angulatus. A single capture of 2 individuals of the sharp-winged crab Oregonia bifurca, which had not previously been encountered in the Sea of Okhotsk, was noted. The main clusters of commercial species of crabs were confined to the northern site at depths of 300-500 m. Of the entire variety of species, only the equidistant crab forms dense aggregations, the stocks of which have been exploited by industry since 2017. Chionoecetes opilio and Ch. angulatus stocks in the area of «polygon» can also recruit the resource base of commercial fishing.

The lack of knowledge, both theoretically and practically, regarding the benefits, functions and methods of making organic fertilizers made most of the residents of Jejel village, Lamongan district use chemical fertilizers or inorganic fertilizers as the main ingredients to increase their agricultural yields. Communities/farmers do not really understand that in the long term the use of inorganic fertilizers will erode nutrients and various important minerals in the soil, causing the soil to become less fertile and in the end this will result in minimal crop yields and even crop failure. Residents complain about the high price of inorganic fertilizers in the market so that the profits generated by residents from agricultural products are smaller and not sufficient to support the economy of farmers in general. Based on the above data, which the author obtained through direct observation and interviews with residents of Jejel village, the author took the initiative to conduct counseling and training on how to make organic fertilizer from cow dung using the main ingredient EM-4 plus other materials around the residents. The choice of cow manure as an alternative to making organic fertilizer is due to the fact that the average resident keeps cows as livestock. This service activity starts from the socialization stage, ensuring the availability of the main ingredients and media for making fertilizer to direct practice with residents. As a result, residents then began to be aware of the benefits of organic fertilizers and the dangers of inorganic fertilizers. Residents also finally realized that the use of organic fertilizers is more cost-effective and interested in starting to use cow manure as a soil fertilizer to replace inorganic fertilizers.

Agriculture is an essential part of our country and is only necessary for its development. The problem here is leaf spot disease, which significantly affects the growth of food production. Food production is considered one of the most important in our nation. We must detect it early and bring it under control. It is important to analyze one of the versions of leaf disease in its development. The existing system of machine learning could not give the proper prediction result of the lead disease prediction and classification. Various plant diseases affect leaf areas, and leaf areas have some black marks. Black marks are one type of leaf disease in plants. Find out the disease levels and accuracy. One standard learning method of deep learning classification has been used to classify leaf disease prediction. Here pre-processing and feature extraction using CNN and feature extraction and type using the RNN-based LSTM method are used. The data has been found in the Kaggle dataset; the total dataset is divided into 20000 plant village dataset images using training, and the validation dataset has available there. This dataset predicts the disease name and related data is collected to gather the leaf disease information. The RNN algorithm result is improved accuracy of identification compared to other methods but best performance for the LSTM method.

Published: August 2023

Gender classification is used in numerous applications such as biometrics, criminology, surveillance, HCI, and business profiling. Although biometric factors like gait, face, hand shape, and iris have been used to classify people into genders, the majority of research has focused on facial traits due to their more recognisable qualities. This research employs fingerprints to classify gender, with the intention of being relevant for future studies. Several methods for gender classification utilising fingerprints have been presented in the literature, including ANN, KNN, Naive Bayes, the Gaussian mixture model, and deep learning-based classifiers. Although these classifiers have shown good classification accuracy, gender classification remains an unexplored field of study that necessitates the development of new approaches to enhance recognition accuracy, computation, and running time. In this paper, a CNN-SVM hybrid framework for gender classification from fingerprints is proposed, where preprocessing, feature extraction, and classification are the three main components. The main goal of this study is to use CNN to extract fingerprint information. These features are then sent to an SVM classifier to determine gender. The hybrid model's performance measures are examined and compared to those of the conventional CNN model. Using a CNN-SVM hybrid model, the accuracy of gender classification based on fingerprints was 99.25%.

Authors: SETIYONO Joko , NABELA Nadia
Published: August 2023

The criminal act of terrorism is a serious crime and an extraordinary crime which has an adverse impact on the sovereignty of the state and the security of the citizens' livelihood. The responsibility of the state in protecting all citizens is an obligation mandated in the constitution (1945 Constitution). Law Number 5 of 2018 is a legal umbrella in carrying out law enforcement efforts, countermeasures and measures to prevent criminal acts of terrorism. The government plays an active role in taking strategic steps to tackle and prevent criminal acts of terrorism by revising Law no. 15 of 2003 became Law Number 5 of 2018, forming the Special Anti-Terror Special Detachment 88 Task Force, as well as the National Counterterrorism Agency (BNPT). The community also plays an active role in efforts to prevent criminal acts of terrorism by having high awareness of the law, increasing knowledge and awareness of the dangers of terrorism, so that they can carry out early detection of potential terrorism and report things that are considered suspicious in the surrounding environment to the authorities.

Published: August 2023

Coronal mass ejections (CMEs) are violent ejections of magnetized plasma from the Sun that can trigger geomagnetic storms, endanger satellite operations, and destroy electrical infrastructures on the Earth. After systematically searching Sun-as-a-star spectra observed by the Extreme Ultraviolet Variability Experiment on board the Solar Dynamics Observatory (SDO) from 2010 May to 2022 May, we identified eight CMEs associated with flares and filament eruptions by analyzing the blue-wing asymmetry of the O iii 52.58 nm line profiles. Combined with images simultaneously taken by the 30.4 nm channel of the Atmospheric Imaging Assembly on board SDO, the full velocity and propagation direction for each of the eight CMEs are derived. We find a strong correlation between geomagnetic indices (Kp and Dst) and the angle between the CME propagation direction and the Sun–Earth line, suggesting that Sun-as-a-star spectroscopic observations at extreme-ultraviolet wavelengths can potentially help to improve the prediction accuracy of the geoeffectiveness of CMEs. Moreover, an analysis of synthesized long-exposure Sun-as-a-star spectra implies that it is possible to detect CMEs from other stars through blue-wing asymmetries or blueshifts of spectral lines.
SO and SiS Emission Tracing an Embedded Planet and Compact 12CO and 13CO Counterparts in the HD 169142 Disk
Authors: Law Charles J. , Booth Alice S. , Öberg Karin I.
Published: August 2023

Planets form in dusty, gas-rich disks around young stars, while at the same time, the planet formation process alters the physical and chemical structure of the disk itself. Embedded planets will locally heat the disk and sublimate volatile-rich ices, or in extreme cases, result in shocks that sputter heavy atoms such as Si from dust grains. This should cause chemical asymmetries detectable in molecular gas observations. Using high-angular-resolution ALMA archival data of the HD 169142 disk, we identify compact SO J = 88 − 77 and SiS J = 19 − 18 emission coincident with the position of a ∼ 2 M
Jup planet seen as a localized, Keplerian NIR feature within a gas-depleted, annular dust gap at ≈38 au. The SiS emission is located along an azimuthal arc and has a morphology similar to that of a known 12CO kinematic excess. This is the first tentative detection of SiS emission in a protoplanetary disk and suggests that the planet is driving sufficiently strong shocks to produce gas-phase SiS. We also report the discovery of compact 12CO and 13CO J = 3 − 2 emission coincident with the planet location. Taken together, a planet-driven outflow provides the best explanation for the properties of the observed chemical asymmetries. We also resolve a bright, azimuthally asymmetric SO ring at ≈24 au. While most of this SO emission originates from ice sublimation, its asymmetric distribution implies azimuthal temperature variations driven by a misaligned inner disk or planet–disk interactions. Overall, the HD 169142 disk shows several distinct chemical signatures related to giant planet formation and presents a powerful template for future searches of planet-related chemical asymmetries in protoplanetary disks.

Authors: Tarhan Merve , Şahin Kaya Dilan , Tetik Nurefşan , Karayılan Simge
Published: August 2023

Background:

Transition shock is prevalent among new graduate nurses. Coping effectively with stress may be essential for a successful transition into practice. The relationship between transition shock and style of coping with stress remains unexplored. The goal of this study was to determine the relationship between style of coping with stress and level of transition shock among new graduate nurses.

Method:

This descriptive, cross-sectional study was carried out with 252 new graduate nurses in two public hospitals in Istanbul, Turkey. Data were collected with a personal information form, the Coping Styles with Stress Scale, and the Nursing Transition Shock Scale.

Results:

Seeking social support, self-confidence, and optimism were the most commonly used styles of coping with stress, with median scores of 7 (range, 6–9), 12 (range, 10–14), and 8 (range, 7–10), respectively. Levels of transition shock for new graduate nurses were moderate, with a median score of 2.61 (range, 2.05–3.33). The helpless (

Conclusion:

The level of transition shock increases with the helpless style and decreases with the use of the social support-seeking style. New graduates can cope with transition shock with simulation-based learning, effective orientation programs, a supportive working environment, and flexibility in the work shift.

Effect of Simulation-Based Training on the Self-Confidence of New Nurses in the Care of Patients With Acute Deterioration and Activation of the Rapid Response Team
Authors: Lambert Carl , Wiencek Clareen , Francis-Parr Jill
Published: August 2023

Background:

New nurses report feeling unprepared and having low levels of self-confidence. High-fidelity simulation (HFS) is frequently used to increase confidence and improve patient safety. This study assessed whether HFS training increased new nurses' self-confidence and activation of the rapid response team (RRT) when caring for patients with clinical deterioration.

Method:

A quality improvement design was used. New nurses on two units at a Level I trauma center completed a 70-minute HFS. The change in self-confidence was measured by Grundy's C-Scale, and the change in percentage of staff-initiated RRT calls versus auto-triggered calls was calculated 3 months after HFS.

Results:

All 12 nurses who participated in the HFS showed improved self-confidence immediately after simulation. A Wilcox-on signed-rank paired data test showed statistically significantly improved confidence scores for all five items of the C-Scale from preintervention to immediately postintervention as well as 5 months later. One unit showed an increase in percentage of staff-initiated RRT calls 3 months postsimulation, and the other unit showed a decline in staff-initiated versus auto-triggered RRT calls.

Discussion:

The HFS increased self-confidence scores from preintervention to immediately postintervention, with the increase sustained 5 months later. However, how this increase translated into practice when activating RRT calls cannot be determined because many factors can influence RRT call patterns.

Conclusion:

The literature review and study results suggest that HFS training embedded into an existing nurse residency program can build self-confidence in caring for patients with clinical deterioration.

IN SILICO MODELING OF PORCINE PERICARDIAL TISSUE LEAFLETS FOR TRANSCATHETER MITRAL VALVE REPLACEMENT
Authors: Jeevan Ranjitha Rebecca , Murari Bhaskar Mohan
Published: August 2023

Tissue valve in combination with a mechanical valve is predominantly used in stented valvular prostheses. Porcine pericardium (PP) is a promising xenograft in addition to the predominately used porcine aortic valve (PAV) and bovine pericardium (BP) in heart valve replacement. Tissue valves are structurally similar to the valve cusps, upon fixation they function as structural and functional units to restore the failing heart valves. In this paper, the characterization, design and performance of PP based prosthetic mitral leaflets are analyzed. Uniaxial tensile test was performed to characterize glutaraldehyde (GA)-treated PP and evaluate its mechanical properties. Finite element methods were instrumental to design and analyze the performance of PP leaflets. Different geometric parameters were analyzed to obtain ideal valve performance. Since geometrical parameters influence valve performance, two leaflet models of trileaflet and quadrileaflet configuration were studied. BP and PAV leaflet models were designed and analyzed as controls to compare the performance of PP. The stress distribution, bending momentum and coaptation pattern from the finite element determine the performance of the geometrical models. PP exhibited anisotropy, promising tensile strength and pliability. A thinner porcine pericardium with promising tensile strength and pliability is ideal for the development of low-profile prosthetic valves. The quadrileaflet model exhibited.
The Russian-Ukrainian Conflict

Thirty-three years after the fall of the Berlin Wall, one thing is obvious: The resolution of several international crises still depends on relations between the West and Russia. Like it or not, this geopolitical situation is a fact which, however, Americans and Europeans have not been duly taken into consideration since 1989. This crisis, which has not stopped, experienced a more expansive phase on February 24, 2022: it is the Russian special military operation for some leaders in Ukraine, Russian interventionism for others, and the war in Ukraine for still others. It is particularly notable in the soaring prices of raw materials essential for the functioning of industries. The Ukrainian crisis has revealed the fragilities of the dependence of certain States and Unions on raw materials, but also certain military fragilities. A critical situation therefore prevails, and many hypotheses remain perceptible given the existence of several scenarios and possible balances. This insight analyzes the current geopolitical situation between blocs and considers a possible vision of the blocs by 2050.

Food security is a major problem worldwide. Ensuring that the crops produced are both safe and wholesome is crucial not only for people as the ultimate consumers of the crops, but also for farmers. Plant diseases are responsible for a significant percentage of crop losses. This alleviates the need for a fast and accurate model to discriminate and identify plants with diseases. The chapter aims to achieve the same through deep learning. The data set used in the work was obtained from Plant Village Dataset. The work customs deuce pre-trained models, EfficientNetB0 and DenseNet121, to citation the traits of the plants. The extracted traits are then fused together through concatenation to allow the model to read the more meaningful crop trait data. This also ensures that the different sets of feature data read by the two models compensate for any feature loss during extraction. It turns out that the above method gives better results associated to other models.
Transendothelial Migration of Human B Cells: Chemokine versus Antigen
Authors: Wang Vivian , Pober Jordan S , Manes Thomas D
Published: August 2023

B cells, like T cells, can infiltrate sites of inflammation, but the processes and B cell subsets involved are poorly understood. Using human cells and in vitro assays, we find only a very small number of B cells will adhere to TNF-activated (but not to resting) human microvascular endothelial cells (ECs) under conditions of venular flow and do so by binding to ICAM-1 and VCAM-1. CXCL13 and, to a lesser extent, CXCL10 bound to the ECs can increase adhesion and induce transendothelial migration (TEM) of adherent naive and memory B cells in 10–15 min through a process involving cell spreading, translocation of the microtubule organizing center (MTOC) into a trailing uropod, and interacting with EC activated leukocyte cell adhesion molecule. Engagement of the BCR by EC-bound anti-κ L chain Ab also increases adhesion and TEM of κ+ but not λ+ B cells. BCR-induced TEM takes 30–60 min, requires Syk activation, is initiated by B cell rounding up and translocation of the microtubule organizing center to the region of the B cell adjacent to the EC, and also uses EC activated leukocyte cell adhesion molecule for TEM. BCR engagement reduces the number of B cells responding to chemokines and preferentially stimulates TEM of CD27+ B cells that coexpress IgD, with or without IgM, as well as CD43. RNA-sequencing analysis suggests that peripheral blood CD19+CD27+CD43+IgD+ cells have increased expression of genes that support BCR activation as well as innate immune properties in comparison with total peripheral blood CD19+ cells.
