Analyzing Factors Influencing Continuance Intention of a Digital Walet: a Study of Digicash by Using Modified UTAUT 2 Model

As time goes, the support for information technology is increasing as the development of internet technology is rapidly increases. E-wallets, which can also be called electronic money, is one of the application of the increasing development of the internet. One of the activities of using the internet is Electronic Money transactions through digital wallets (e-wallets). In 2020, bank bjb launched its e-wallet service, Digicash, entering the industry. However, Digicash has observed relatively low user numbers and transactions compared to its competitors like Gopay and OVO. This research aims to analyze the factors that influences user’s intention of contiuing the use of Digicash application to adress the issue. The theoretical approach employed is the UTAUT 2 model, developed by Venkatesh, Thong, and Xu in 2012. Additionally, this study incorporates additional factors such as Price Saving Orientation, Trust, Perceived Security, and Perceived Privacy to modify the UTAUT2 model. Data collection involved distributing online questionnaires via Google Forms to 464 respondents residing in Indonesia. The questionnaire consisted of 32 questions from 8 constructs. The data analysis technique employed in this study is Structural Equation Modeling (SEM) with SmartPLS 4 Software.The results indicate that the factors influencing the continuance intention to use Digicash, ranked from highest to lowest, are Social Influence, Price Saving Orientation, Perceived Risk, Hedonic Motivation, Habit, and Performance Expectancy. The model’s category is considered 'good' as it can predict the continuance intention of consumers towards Digicash services in Indonesia with an R2 value of 56%. Moreover, the Age variable is moderated by Habit. This model can assist the management of bank bjb, the creator of Digicash, in making decisions to enhance and maintain the continuance intention to use Digicash by paying attention to the identified factors and indicators.
Just a crush? Contamination of archaeological samples by different grinding media

A chert cobble from an archaeological quarry on southern Baffin Island, Canada, was divided and crushed using five different methods: i) agate mortar and pestle, ii) stainless steel shatterbox, iii) tungsten carbide shatterbox, iv) alumina ceramic shatterbox, and v) zirconia ceramic shatterbox. Powders produced by each method were submitted for acid digestion and analysis by inductively coupled plasma mass spectrometry. The trace element results indicate that different crushing media can contribute significant trace element contamination to chert during the grinding process. These results demonstrate the need for an informed approach to the selection of sample preparation methods when submitting archaeological samples for solution or pellet based geochemical analysis.
MPPT with INFO Algorithm Tuned Nonlinear PI Control for a PV Array

In real-time PV applications, it is a problem that the maximum benefit cannot be obtained from PV systems at all times due to the nonlinearity of the PV structure and the dynamic nature of meteorological conditions. Maximum power point tracking (MPPT) is used to overcome this problem and to benefit from PV systems in the most efficient way. In this study, an MPPT method based on the perturb&observe (P&O) technique with nonlinear proportional-integral (NPI) control is proposed. In this method, the parameters of the NPI are adjusted with weighted mean of vectors (INFO) algorithm. Integral of time-weighted absolute error (ITAE) performance index is used for parameter setting, and control parameter behavior is added to the ITAE index to prevent control parameter noises. To validate the proposed method, it is compared with the classical PI control whose parameters are adjusted with the INFO algorithm. The proposed method exhibits 59% faster settling and 63% less overshoot in response to a pulse radiation change of 500W/m2. In addition, performance of the proposed method is 42% better according to the ITAE index. Consequently, it is confirmed that the proposed method is promising for future studies due to its simplicity, fast response, and these satisfactory results.
British scholarship on Greek colonisation in context1780-1990

This thesis examines British scholarly perceptions of Greek colonisation from the eighteenth century to the present. Beginning with a study of the ancient sources for Greek colonisation and the key themes which preoccupied ancient authors, the thesis proceeds to argue that, modifying recent interpretations of work from this age of empire, British scholarship did not, as a whole, simplistically distort ancient evidence so as to create a version of Greek colonisation which mirrored, in a self-congratulatory way, contemporary British experiences. We should therefore position this scholarship within its appropriate historical context (with special attention to politics, empire, colonisation, and perceptions of antiquity). In addition to enabling us to trace the impact of the great events of the modern era upon classical scholarship, in doing so we can also gain insight into the complexities, hopes, and anxieties which characterised British thinking about such themes as empire, colonisation, political freedom, and the place of Western civilisation in historical perspective.
Wasatchian (Early Eocene) pollen floras from the Red Hot Truck Stop, Mississippi, USA

Sediments at the Red Hot Truck Stop (RHTS), Mississippi, USA are important because they contain the lowest latitude record of both the earliest known Eocene plant and mammal fossils in North America. The RHTS contains the uppermost Tuscahoma Formation and the lowermost part of the basal Bashi and Hatchetigbee formations. The Tuscahoma Formation is composed of glauconitic sands and silts that represent estuarine to shallow marine sediments. Faunal remains indicate that the RHTS section belongs to the Wasatchian North American land mammal age and specifically to the lower Graybullian subdivision. Pollen and spore floras from the RHTS are moderately diverse (113 taxa) and contain families that today are associated with warm‐adapted vegetation types such as Annonaceae, Bombacaceae, Burseraceae and palms. Eocene first occurrences are represented by Brosipollis sp. , Celtispollenites sp. , Interpollis microsupplingensis, cf. Nuxpollenites psilatus, Platycarya spp. , Retistephanocolporites sp. and Symplocos? contracta and by one genus of pteridophyte spore (Granulatisporites sp.). The overall composition and within‐sample diversity of the sporomorph flora is more similar to the Hatchetigbee Formation (early Eocene) than to the middle Tuscahoma Formation (late Palaeocene) but among‐sample diversity remains unchanged across the Palaeocene/Eocene boundary. The distinct composition of the RHTS demonstrates that floral change across the Palaeocene/Eocene boundary is complex and composed of several phases of floral change.
A LiDAR survey of Stromboli volcano (Italy): Digital elevation model-based geomorphology and intensity analysis

LiDAR (Light Detection and Ranging) is a novel and very useful active remote sensing system which can be used to directly identify geomorphological features as well as the properties of materials on the ground surface. In this work, LiDAR data were applied to the study of the Stromboli volcano in Italy. LiDAR data points, collected during a survey in October 2005, were used to generate a Digital Elevation Model (DEM) and a calibrated intensity map of the ground surface. The DEM, derived maps and topographic cross-sections were used to complete a geomorphological analysis of Stromboli, which led to the identification of four main geomorphological domains linked to major volcanic cycles. Moreover, we investigated and documented the potential of LiDAR intensity data for distinguishing and characterizing different volcanic products, such as fallout deposits, epiclastic sediments and lava flows.
Depositional Setting of Upper Cretaceous-Lower Tertiary Currant Creek Formation, North-Central Utah

Abstract Braided streams within a humid alluvial fan network largely deposited the Cretaceous through early Tertiary Currant Creek Formation in the northwestern Uinta Basin, northeast Utah. These fans extended into the north-central Utah foreland basin from the tectonically active Sevier orogenic belt on the west. The synorogenic conglomerate ranges in type from boulder-sized clast-supported strata to pebble-and granule-sized matrix-supported conglomerate. The interbedded sandstone increases in textural maturity with distance from source areas. The sandstone composition ranges from quartz arenite to lithic arenite. Conglomerate and sandstone that formed as longitudinal bars, channel fills or sieve deposits characterize the proximal fan facies. Distal facies consist principally of sandstone and finer grained clastic strata that were deposited within channels or overbank areas.
Ocean Currents along a Nearshore Frontal Zone on the Continental Shelf of the Southeastern United States

Abstract River and estuarine discharges mix to form a frontal zone along a 400 km length of the coast of the south-eastern United States. The frontal width extends from the coast outward 10–20 km. Two ships, anchored across the frontal zone during autumn, obtained simultaneous hourly profiles of currents and density for, five consecutive tidal cycles. The frontal zone contained a baroclinic coastal current flowing southward. The flow was strongly convergent; more water entered on the coastal side than exited on the seaward side. Much of the inflow was apparently turned southward. Thus, the frontal zone acted as a dynamic barrier that inhibited the advection of mixed river discharge farther offshore. A thermal wind relationship suitably predicted vertical shear through the frontal zone. Bottom friction seemed to play only a secondary role. Data suggest that the baroclinic coastal current was modified by the presence of a barotropic current seaward of the frontal zone. The force responsible for the barotrop.
A Modeling Perspective on Cloud Radiative Forcing

Radiation fields from a perpetual July integration of a T106 version of the ECMWF operational model are used to identify the most appropriate way to diagnose cloud radiative forcing in a general circulation model, for the purposes of intercomparison between models. Differences between the methods 1 and 2 of Cess and Potter (1987) and a variant method are addressed. Method 1 is shown to be the least robust of all methods, due to the potential uncertainties related to persistent cloudiness, length of the sampling period, and biases in retrieved clear sky quantities due to insufficient sampling of the diurnal cycle. Method 2 is proposed as an unambiguous way to produce consistent radiative diagnostics for intercomparing model results. The impact of the three methods on the derived sensitivites and cloud feedbacks following an imposed change in sea surface temperature is discussed. The sensitivity of the results to horizontal resolution is considered by using the diagnostics from parallel integrations with T21 version of the model. 20 refs., 2 figs., 1 tab.
Siracusa: A Low-Power On-Sensor RISC-V SoC for Extended Reality Visual Processing in 16nm CMOS

Extended Reality (XR) has become increasingly popular in recent years, with applications in entertainment, education, healthcare, and more. However, mass adoption of XR technology still faces several challenges in meeting stringent latency and power consumption requirements. On-sensor computing, where a capable XR processor is tightly packaged with an image sensor, is a promising technology that can help address these challenges as it provides several benefits, including reduced data analysis latency, low power consumption, small form factor, and greater privacy. This work introduces Siracusa, an on-camera computing platform for next-generation XR devices. Siracusa features a flexible mixed-precision Machine Learning (ML) accelerator and a cluster of application-tuned RISC-V cores, sharing a highly configurable on-chip memory hierarchy designed to minimize expensive data copies. As a result, Siracusa achieves a peak energy efficiency of 9.9 $\mathrm{T}\mathrm{O}\mathrm{p}/\mathrm{J}$ for deep neural network (DNN) inference, an increase of 1.2 x compared to similar designs, while supporting complex, heterogeneous application workloads, which combine ML with conventional signal processing and control.
Patterns of Coherent Climate Signals in the Indian Ocean during the 20th Century

QBO, ENSO, and BDO fluctuations are identified in the Indian Ocean from a joint frequency domain analysis of sea surface temperature (SST) and sea level pressure (SLP) conducted over the 20th Century. Within the ENSO band (3‐ to 7‐year period), local fractional variance (LFV) is maximum near 3.4‐year period, revealing spatially coherent SST and SLP variability propagating eastward from the Horn of Africa and southwest Indian Ocean respectively, toward the eastern tropical Indian Ocean. Within the QBO band (2.1‐ to 2.8‐ year period), LFV is maximum near 2.2‐year period revealing spatially coherent SST and SLP variability propagating northward and eastward from Southwestern Ocean, toward the South China Sea. The 3.4‐year period ENSO signal diminished in intensity in the 1920s and 1950s, whilst the 2.2‐year period QBO signal diminished in the 1910s, 1940s, and 1950s, as observed for the global QBO and ENSO signals [ White and Tourre, 2003 ].
Kelvin-Helmholtz waves at the Earth's magnetopause: Multiscale development and associated reconnection

[1] We examine traversals on 20 November 2001 of the equatorial magnetopause boundary layer simultaneously at ∼1500 magnetic local time (MLT) by the Geotail spacecraft and at ∼1900 MLT by the Cluster spacecraft, which detected rolled-up MHD-scale vortices generated by the Kelvin-Helmholtz instability (KHI) under prolonged northward interplanetary magnetic field conditions. Our purpose is to address the excitation process of the KHI, MHD-scale and ion-scale structures of the vortices, and the formation mechanism of the low-latitude boundary layer (LLBL). The observed KH wavelength (>4 × 104 km) is considerably longer than predicted by the linear theory from the thickness (∼1000 km) of the dayside velocity shear layer. Our analyses suggest that the KHI excitation is facilitated by combined effects of the formation of the LLBL presumably through high-latitude magnetopause reconnection and compressional magnetosheath fluctuations on the dayside, and that breakup and/or coalescence of the vortices are beginning around 1900 MLT. Current layers of thickness a few times ion inertia length ∼100 km and of magnetic shear ∼60° existed at the trailing edges of the vortices. Identified in one such current sheet were signatures of local reconnection: Alfvenic outflow jet within a bifurcated current sheet, nonzero magnetic field component normal to the sheet, and field-aligned beam of accelerated electrons. Because of its incipient nature, however, this reconnection process is unlikely to lead to the observed dusk-flank LLBL. It is thus inferred that the flank LLBL resulted from other mechanisms, namely, diffusion and/or remote reconnection unidentified by Cluster.
Enhancing the

Whatfactors determine the quality of end-user computing services in local governments? In a survey of 1,869 end users in 46 U.S. cities, the authors examine three major "controllable"factors that the literature indicates might influence the quality of computing sewices: (1) the structure of service provision, (2) the level of techno-logicalproblems, and (3) the service orientation of computing service specialists. The survey results do not support the popular argument that structuralfactors (e.g., whether computing services are centralized or decentralized within an organization) are most important; both the level of operational problems and the attitudes of the service providers were more significant. Thefind-ings were especially supportive of explanations that focus on sevice-orientationfactors, leading the authors to stress strategiesfor service improvement that concentrate on the "sociotechnical interface" (ST! ) between end users and computing service providers.
clinical effect of a positive surgical margin after hepatectomy on survival of patients with intrahepatic cholangiocarcinoma

Background: Several unfavorable prognostic factors have been proposed for peripheral cholangiocarcinoma (PCC) in patients undergoing hepatectomy, including gross type of tumor, vascular invasion, lymph node metastasis, a high carbohydrate antigen 19-9 level, and a positive resection margin. However, the clinical effect of a positive surgical margin on the survival of patients with PCC after hepatectomy still needs to be clarified due to conflicting results. Methods: A total of 224 PCC patients who underwent hepatic resection with curative intent between 1977 and 2007 were retrospectively reviewed. Eighty-nine patients had a positive resection margin, with 62 having a microscopically positive margin and 27 a grossly positive margin (R2). The clinicopathological features, outcomes, and recurrence pattern were compared with patients with curative hepatectomy. Results: PCC patients with hepatolithiasis, periductal infiltrative or periductal infiltrative mixed with mass-forming growth, higher T stage, and more advanced stage tended to have higher positive resection margin rates after hepatectomy. PCC patients who underwent curative hepatectomy had a significantly higher survival rate than did those with a positive surgical margin. When PCC patients underwent hepatectomy with a positive resection margin, the histological grade of the tumor, nodal positivity, and chemotherapy significantly affected overall survival. Locoregional recurrence was the most common pattern of recurrence. Conclusion: A positive resection margin had an unfavorable effect on overall survival in PCC patients undergoing hepatectomy. In these patients, the prognosis was determined by the biology of the tumor, including differentiation and nodal positivity, and chemotherapy increased overall survival.
Classification of the LCVF AVIRIS test site with a Kohonen artificial neural network

We present a classification of an AVIRIS spectral image of the Lunar Crater Volcanic Field (LCVF). Geologic mapping from such data is made possible by distinctive mineral signatures: absorption features and the shape of the spectral continuum. The subtle spectral shape differences between some of the geological units in this scene along with the high dimensionality of the spectral presents a challenging pattern recognition task. We found an artificial neural network powerful in separating 13 geological units based on the full spectral resolution. The LCVF, in northern Nye County, Nevada, was the primary focus of the NASA-sponsored Geologic Remote Sensing Field Experiment in the summer of 1989. It consists of over 100 square miles of Quaternary basaltic pyroclastic and flow deposits. These deposits lie atop ignimbrites and silicic lava flows of Tertiary age and in turn are overlain by Quaternary alluvial and playa deposits. This AVIRIS image was collected on September 29, 1989 at 11:44 at 11:44 PDT. The 256-by-256 pixel subsection in this study contains oxidized basaltic cinder deposits, the southern half of the Lunar Lake playa, and outcrops of the Rhyollite of Big Sand Spring Valley. Vegetation in LCVF is sparse, but locally abundant within washes and near springs.
Advantages of Intravenous Administration of Amisulpride Over Ondansetron for Prophylaxis of Postoperative Nausea and Vomiting: An Educational Module

Title: Advantages of Intravenous Administration of Amisulpride Over Ondansetron for Prophylaxis of Postoperative Nausea and Vomiting: An Educational Module Impact Statement: In patients undergoing general anesthesia, the administration of intravenous amisulpride has proven to be effective in preventing Post Operative Nausea and Vomiting (PONV) while having a safer profile when compared to ondansetron. Background: PONV is, after pain, the second most frequent complaint after surgery, and it may contribute to severe complications, decrease patient satisfaction, extend the hospital stay and increase healthcare costs. Despite the potential for serious side effects, ondansetron remains the preferred drug used to prevent PONV. Objective: This project aims to compare the effectiveness and safety profile of ondansetron and amisulpride as a prophylaxis for PONV and present the findings through an educational module to anesthesia providers and assess the degree of knowledge gained. Method: We conducted a literature review comparing amisulpride and ondansetron as prophylactic agents for PONV. We created an online educational module to present to anesthesia providers and a pre and post surveys to assess the degree of knowledge acquired. The project was developed in a large level 1 trauma center, using anonymous and online platform for survey and module delivery and data collection. Results: We found amisulpride to be effective as a prophylactic drug for PONV; it also decreases the severity of nausea in the high-risk patient. Amisulpride has a safer profile and fewer potential for side effects when compared to ondansetron. Discussion: Data from surveys shows anesthesia providers increased their knowledge about PONV and effective prophylaxis treatments after the educational module. Small sample size, short duration of this project, and the use of online platform were limitations of this project. Conclusion: The educational module improved anesthesia providers’ knowledge and attitude about Postoperative Nausea and Vomiting and the administration of intravenous amisulpride as an effective and safe prophylactic alternative.
Occupational Hazard Prevention And Control In A Quarry Environment: Exposure To Airborne Dust

Dust emissions may be considered among the most critical hazards to be found in quarries due to the design and nature of this working environment. Not only does dust impair the quality of the air from an environmental perspective, but it also impinges on the health and safety of workers. Those responsible for the quarry must demonstrate their compliance with industry standards and legal regulations, and are thereby required to implement several dust mitigation techniques in order to comply with air quality standards and pollutant emission limits. The aim of this paper is firstly to evaluate how quarry workers are affected by the mitigation techniques designed to reduce the impact of dust emissions on the environment. Secondly, an attempt is made to determine which of the proposed strategies is the most effective both in reducing emissions and in reducing the workers’ exposure, and thus defining a suitable strategy on which to focus. The analysis is carried out in four consecutive phases. In the first, the PM10 concentration is sampled and the daily exposure of workers to the respirable fraction of airborne dust is measured. In the second, mitigation techniques, are applied to the main sources of dust according to the technical guidelines stipulated in international standards and norms. In the third phase, the pollutant concentration (PM10) is resampled at various points throughout the quarry plant and a further sampling campaign is carried out with personal samplers to assess workers’ exposure and their daily dose. A comparison of these two sets of values allows both the effectiveness of the applied dust mitigation techniques and the influence of PM10 concentration on the respirable fraction of airborne dust to be quantified. In the final phase, personal samplers are used in order to test the Functional Analysis Space Technique risk assessment procedure in forecasting the daily dose.
