Anomaly Detection using Generative Adversarial Network VAE
Authors: Jaiprakash Prajapati  , Prof. Nilesh Choudhary
Published: March 2023

Fraudulent credit card transactions continue to be one of the problems facing businesses and banks. It causes us to lose billions of dollars each year. Designing efficient algorithms is one of the most important challenges in this field. This paper aims to propose an efficient approach that automatically detects fraud in credit card transactions using Generative Adversarial Network Variational Auto encoders.
The effectiveness of the proposed method (Generative Adversarial Network VAE) has been proved in identifying fraud in actual data from transactions made by credit cards. However, the typical credit card data set presents an imbalanced classification landscape due to highly skewed class distributions. Researchers have proposed several strategies to address these imbalances, but draw backs still remain. The proposed method is tested on an open credit card fraud dataset, which contains 20 million transactions generated from a multi-agent virtual world simulation performed by IBM. Experimental results show that the VAE method performs better than traditional deep neural network methods. Through experiments, compared with the VAE and traditional fully connected neural networks, the results showed the proposed algorithm improves the classification accuracy of a minority class of imbalanced datasets.
Baptiste-Louis Garnier e Louis Hachette: contatos internacionais, direitos autorais e tradução
Authors: Granja Lucia , Bezerra Valéria Cristina
Published: March 2023

A definição do repertório literário no século XIX em diferentes países foi decorrente da atuação de agentes, que estabeleciam redes internacionais de contatos e, a partir delas, efetuavam escolhas de obras que atenderiam ao leitorado e delineavam estratégias de atuação no mercado livreiro. Baptiste-Louis Garnier entreteve relação com diversos intermediários e profissionais do campo editorial, coadunando suas ações com os interesses das pessoas com quem negociava, com as demandas de seu público e, claro, com seus próprios anseios de êxito de seus empreendimentos. Este artigo tem como objetivo compreender as ações de Garnier e sua interferência no delineamento da literatura traduzida oferecida aos leitores brasileiros. A partir de correspondências desse editor enviadas a Louis Hachette, buscaremos analisar como a preservação dos direitos autorais de autores estrangeiros ou sua violação impactou a circulação no Brasil de obras traduzidas de dois dos mais célebres romancistas de seu tempo, Jules Verne e Condessa de Ségur.
Analyzing translations of culturally-bound expressions in span of Time
Authors: Afrouz Mahmoud
Published: March 2023

Translation of masterpieces of a nation’s classic literature poses great challenges to translators. One of the major challenges is the issue of dealing with culturally-bound expressions (CBEs). In the current study, the researcher aimed at exploring the effect of time-span on rendering Sa’di’s Gulistan. To this end, two English translations by Ross (1823) and Arnold (1899) were studied based on Davies’s (2003) model. She has proposed seven procedures among which ‘Preservation’, ‘Transformation’, and ‘Omission’ were deemed low-productive. These, together with ‘Mistranslated’ CBEs, were regarded as a criterion for assessing the performance of the two translators on lexical-semantic level. As far as rendering CBEs were concerned, findings of the study showed that time-span has had no positive effect on avoiding low-productive procedures. Since most of the challenging CBEs were categorized in the realm of ‘Social life’ and ‘Religion’, the prospective translators, who intend to re-translate a classical Persian masterpiece, are highly recommended to gain adequate knowledge in the two realms. Inaccessibility to other translations of the Gulistan was a limitation of the study; therefore, researchers are suggested to find other translations from the 20th or 21st century and also focus on other potential factors affecting the quality of rendering CBEs.
A critical analysis of the celebrity chef Jamie Oliver's discourse of fastness and BBC Persian’s dubbing strategies
Authors: Afzali Katayoon , Hadi Maryam
Published: March 2023

Translation Studies scholars have recently indicated the emergence of a political ecology of translation. Viewing this new trend, the present study aimed to explore discoursal features of Jamie Oliver's talk in Jamie’s Thirty Minute Meals cookery show and the way they were rendered in the dubbed version broadcast by BBC Persian. To this end, the comparative model of research and the notion of tertium comparationis was used. To analyze the discoursal features of Jamie Oliver, the principles of the grounded theory were applied. The findings indicate that the predominant stylistic features of fastness in Jamie Oliver’s talk are repetition of title, using time phrases indicating fastness, and using words implying easiness and briskness. Analysis of the dubbed version revealed that all the identified expressions of fastness were translated literally into Persian, though they do not sound natural. In other words, in Toury’s (1980) term adequate or source-oriented strategies were used to dub the show into Persian. The findings can shed some light on the realization of food colonization in translation.

Published: March 2023

Objectives

Shared decision-making between rheumatologists and patients has become an overarching principle in current treatment recommendations in rheumatoid arthritis (RA). Therefore, in the present study, we aimed to assess the satisfaction of patients with RA with their treatment and to investigate the associated factors.

Material and methods

A cross-sectional study was carried out in the Rheumatology Department of Mongi Slim Hospital. We included adults with RA receiving their current disease-modifying anti-
rheumatic drugs for at least 12 months.
Satisfaction among patients was assessed by the Treatment Satisfaction Questionnaire for Medica-tion (TSQM) and it was defined by a score ≥ 80%. The factors indirectly influencing patient satisfac-tion that were assessed were: satisfaction with medical care management, disease activity, function-al impact, professional impact, and the impact of RA. Multivariable regression analysis was applied to determine the predictors of satisfaction.

Results

We included 70 patients (63 female/7 male) with a mean age of 57.8 ±10.6 years. The mean disease duration was 13.71 ±7.2 years.
Mean TSQM scores were 65.42 ±14.77 for convenience, 68.71 ±18 for effectiveness, 70.60 ±24.5 for side effects, and 67.95 ±17.10 for global satisfaction. Satisfaction rates were: 20% for convenience, 39% for effectiveness, 46% for side effects and 30% for global satisfaction.
In multivariable analysis, the predictors of global dissatisfaction were Rheumatoid Arthritis Impact of Disease (RAID) overall score (p = 0.003) and the degree of physical difficulties (p = 0.001). Satisfac-tion with the physician was correlated with better global satisfaction (p = 0.029). Difficulties in adapt-ing to RA (p = 0.043) and current treatment with biologics (p = 0.027) were predictors of dissatisfaction with convenience. Predictors of dissatisfaction with efficiency were the RAID over-all score (p = 0.032) and the difficulties of adapting to RA (p = 0.013). The predictors of satisfaction with side effects were a lower degree of interference with domestic work (p = 0.02) and better in-volvement of the patient in the treatment decision (p = 0.014).

Conclusions

The satisfaction with the attending physician, the participation in the treatment decision, and the impact of RA seem to influence treatment satisfaction the most. These data suggest that a better understanding of patients’ medical needs and preferences would improve satisfaction outcomes.
Pope Gregory IX (1227-1241):
Power and Authority
Authors: Smith Damian J.
Published: March 2023

As Cardinal Hugo and as pope, Gregory was one of the dominant figures in the history of the papacy of the High Middle Ages. Coming to prominence under Pope Innocent III, Hugo played an important political role, particularly as legate on various occasions, as well as being a major promoter of the new religious orders. As pope, his battle with Emperor Frederick II is one of medieval history’s most absorbing conflicts. But he also acted as peacemaker, promoter of the Crusades, instigator of mission for the sake of conversion, refomer of the Curia, patron of arts and liturgy, and as a passionate advocate of Church reform. His decretal collection, the Liber Extra, was the most influential of the Middle Ages. A full examination of Gregory’s pontificate is very long overdue. The current volume brings together a team of international scholars, each of them expert in dealing with a particular aspect of the pontificate, and provides what will be a collection of studies of lasting scholarly value on a central figure of the medieval papacy.

Poesia e verdade: um diálogo entre Ferreira Gullar e H.-G. Gadamer
Authors: Viana Passos Rodrigo
Published: March 2023

O presente texto pretende realizar um diálogo introdutório entre o filósofo alemão H.-G. Gadamer e o poeta brasileiro Ferreira Gullar. Apesar de caminhos iniciais distintos, eles confluem para um tema comum a ambos e extremamente central para o humano: a experiência artística como acontecimento da verdade. É um autêntico movimento de defesa contra alguns efeitos nefastos da tecnização do mundo. Nesse caminho, pensar a poesia como verdade nos possibilita reabilitar sua voz para nós, na medida em que nos revela que, para além de puro objeto estético, a arte em geral – e assim a “literatura” também – é, como nos ensina Gadamer, uma [re]presentação (Darstellung) do ser, e sua linguagem é a própria possibilidade de recriarmos o mundo linguisticamente configurado, e, assim, mudarmos a nós mesmos – uma exigência prática. Da parte de Ferreira Gullar, um testemunho categórico disso é sua obra poética engajada, não apenas socialmente, mas antes de mais nada poeticamente – englobando de maneira original tudo aquilo que podemos chamar de mundo –, e que possui como momento áureo o Poema sujo. Nos valeremos do espaço de jogo poético deste poema de Ferreira Gullar para pensarmos com ambos como é possível nos dias atuais fazermos e experimentarmos arte verdadeiramente.
Heidegger e a essência mundana do existir humano
Authors: Dias Jose Ricardo Barbosa
Published: March 2023

Trata-se de apresentar o sentido existencial de mundo em Heidegger como a essência mesma do existir humano na contraposição, que ele mesmo articulou, com o sentido metafísico de mundo tal como se dá em Descartes. Heidegger se depara com esse sentido existencial de mundo já no início do pensamento ocidental. Contudo, segundo ele, esse sentido se encontra ali, e até o momento atual, indeterminado em seu nexo com o Dasein. Ele, então, pretende tirar esse sentido dessa indeterminação. Tal pretensão heideggeriana é o que aqui apresentamos ao mostrar que essa indeterminação se desfaz nele a partir do momento em que o mesmo faz coincidir a mundanidade do mundo com a transcendência ou existir mesmo do Dasein.
Automatic Stop Orders for Opioids
Authors: Jafari Zahra , Bailey Sharon
Published: March 2023

Automatic stop orders may reduce or have no significant effect on opioid-based prescriptions at the institutional level.

We did not find any evidence regarding a range of clinical outcomes (e.g., rates of opioid dependence, misuse, and diversion; reduction in opioid dependence, health-related quality of life, and adverse events) associated with automatic stop orders.

We did not find any evidence-based guidelines regarding the use of automatic stop orders for opioid prescriptions.

Given the limited number and observational, nonrandomized design of the included studies, as well as the absence of any evidence-based guidelines regarding the use of automatic stop orders for opioid prescriptions, it was difficult to draw any firm conclusions about the clinical effectiveness of automatic stop orders for opioid prescriptions in the Canadian context.

Die Raum- und Ufersäuberung des Flusses Mieresch im Jahre 1778 und ihre Auswirkungen auf die Navigation und Landschaft in Siebenbürgen
Authors: Rus Dorin-Ioan
Published: March 2023

Diese Studie konzentriert sich auf die Beschreibung der technischen Neuerungen in Bezug auf den Transport von Salz im habsburgischen Siebenbürgen des 18. Jahrhunderts. Die ab 1699 beginnende habsburgische Landesverwaltung maß dem Salzbergbau und dem Salzhandel große Bedeutung zu. Der Transport von Salz erfolgte auf dem Landweg, wenn es der Zustand der Straßeninfrastruktur zuließ, und auf dem Wasserweg, was die billigere Option war. Im Zusammenhang mit der lokalen Holzkrise, insbesondere der gravierenden Knappheit an Eichenholz, das für den Bau von Frachtschiffen für den Salztransport benötigt wird, war der habsburgische Staat gezwungen, für diesen Zweck auf Nadelholz umzusteigen, da es verfügbarer und billiger war . Da die neuen Nadelholzschiffe jedoch zerbrechlicher und unfallanfälliger waren, mussten bestimmte schiffbare Wasserstraßen in Siebenbürgen reguliert werden.Die Primärquellen für diese Studie wurden in Archiven in Wien, Cluj-Napoca und Budapest gesammelt.

Abstract. Soot, or black carbon (BC), aerosol is a major climate
forcer with severe health effects. The impacts depend strongly on particle
number concentration, size and mixing state. This work reports on two field
campaigns at nearby urban and rural sites, 65 km apart, in southern Sweden
during late summer 2018. BC was measured using a single-particle soot
photometer (SP2) and Aethalometers (AE33). Differences in BC concentrations
between the sites are driven primarily by local traffic emissions.
Equivalent and refractory BC mass concentrations at the urban site were on
average a factor 2.2 and 2.5, with peaks during rush hour up to a factor
∼4, higher than the rural background levels. The number
fraction of particles containing a soot core was significantly higher in the
city. BC particles at the urban site were on average smaller by mass and had
less coating owing to fresh traffic emissions. The organic components of the
fresh traffic plumes were similar in mass spectral signature to
hydrocarbon-like organic aerosol (HOA), commonly associated with
traffic. Despite the intense local traffic (∼ 30 000 vehicles
passing per day), PM1, including organic aerosol, was dominated by aged
continental air masses even at the curbside site. The fraction of thickly
coated particles at the urban site was highly correlated with the mass
concentrations of all measured chemical species of PM1, consistent with
aged, internally mixed aerosol. Trajectory analysis for the whole year
showed that air masses arriving at the rural site from eastern Europe
contained approximately double the amount of BC compared to air masses from
western Europe. Furthermore, the largest regional emissions of BC transported to the rural site, from the Malmö–Copenhagen urban area, are discernible above background levels only when precipitation events are excluded. We show
that continental Europe and not the Malmö–Copenhagen region is the
major contributor to the background BC mass concentrations in southern
Sweden.

Abstract. Phase correlation (PC) is a well-known method for estimating cloud motion vectors (CMVs) from infrared and visible spectrum images. Commonly, phase shift is computed in the small blocks of the images using the fast Fourier transform. In this study, we investigate the performance and the stability of the blockwise PC method by changing the block size, the frame interval, and combinations of red, green, and blue (RGB) channels from the total sky imager (TSI) at the United States Atmospheric Radiation Measurement user facility's Southern Great Plains site. We find that shorter frame intervals, followed by larger block sizes, are responsible for stable estimates of the CMV, as suggested by the higher autocorrelations. The choice of RGB channels has a limited effect on the quality of CMVs, and the red and the grayscale images are marginally more reliable than the other combinations during rapidly evolving low-level clouds. The stability of CMVs was tested at different image resolutions with an implementation of the optimized algorithm on the Sage cyberinfrastructure test bed. We find that doubling the frame rate outperforms quadrupling the image resolution in achieving CMV stability. The correlations of CMVs with the wind data are significant in the range of 0.38–0.59 with a 95 % confidence interval, despite the uncertainties and limitations of both datasets. A comparison of the PC method with constructed data and the optical flow method suggests that the post-processing of the vector field has a significant effect on the quality of the CMV. The raindrop-contaminated images can be identified by the rotation of the TSI mirror in the motion field. The results of this study are critical to optimizing algorithms for edge-computing sensor systems.
Deep learning models for generation of precipitation maps based on numerical weather prediction
Authors: Rojas-Campos Adrian , Langguth Michael , Wittenbrink Martin , Pipa Gordon
Published: March 2023

Abstract. Numerical weather prediction (NWP) models are atmospheric simulations that imitate the dynamics of the atmosphere and provide high-quality forecasts. One of the most significant limitations of NWP is the elevated amount of computational resources required for its functioning, which limits the spatial and temporal resolution of the outputs. Traditional meteorological techniques to increase the resolution are uniquely based on information from a limited group of interest variables. In this study, we offer an alternative approach to the task where we generate precipitation maps based on the complete set of variables of the NWP to generate high-resolution and short-time precipitation predictions. To achieve this, five different deep learning models were trained and evaluated: a baseline, U-Net, two deconvolution networks and one conditional generative model (Conditional Generative Adversarial Network; CGAN). A total of 20 independent random initializations were performed for each of the models. The predictions were evaluated using skill scores based on mean absolute error (MAE) and linear error in probability space (LEPS), equitable threat score (ETS), critical success index (CSI) and frequency bias after applying several thresholds. The models showed a significant improvement in predicting precipitation, showing the benefits of including the complete information from the NWP. The algorithms doubled the resolution of the predictions and corrected an over-forecast bias from the input information. However, some new models presented new types of bias: U-Net tended to mid-range precipitation events, and the deconvolution models favored low rain events and generated some spatial smoothing. The CGAN offered the highest-quality precipitation forecast, generating realistic outputs and indicating possible future research paths.
GeoINR 1.0: an implicit neural representation network for three-dimensional geological modelling
Authors: Hillier Michael , Wellmann Florian , de Kemp Eric , Schetselaar Ernst , Brodaric Boyan , Bédard Karine
Published: March 2023

Abstract. Implicit neural representation (INR) networks are emerging as a powerful framework for learning three-dimensional shape representations of complex objects. These networks can be used effectively to implicitly model three-dimensional geological structures from scattered point data, sampling geological interfaces, units, and orientations of structural features, provided appropriate loss functions associated with data and model constraints are employed during training. The flexibility and scalability of these networks provide a potential framework for integrating new forms of related geological data and knowledge that classical implicit methods cannot easily incorporate. We present a methodology using an efficient INR network architecture, called GeoINR, consisting of multilayer perceptrons (MLP) that advance existing implicit methods for structural geological modelling. The developed methodology expands on the modelling capabilities of existing methods using these networks by: (1) including unconformities into the modelling, (2) introducing constraints on stratigraphic relations as well as global smoothness along with their associated loss functions, and (3) improving training dynamics through the geometrical initialization of learnable network variables. These three enhancements enable the modelling of more complex geology, improved data fitting characteristics, and reduction of modelling artifacts in these settings, as compared to existing INR frameworks for structural geological modelling. A provincial scale case study for the Lower Paleozoic portion of the Western Canadian Sedimentary Basin (WCSB) in Saskatchewan, Canada is presented to demonstrate the modelling capacity of the MLP architecture using the developed methodology. Modelling results illustrate the method’s capacity to fit noisy datasets, represent unconformities, and implicitly model large regional scale three-dimensional geological structures.

The heart failure group's left ventricular torsion parameters were all lower than the control group's: Peak-AR (4.56 ± 2.960 versus 10.41 ± 3.060; p<0.001), Peak-BR (-4.04 ± 2,250 vs -8.97 ± 2.750; p<0.001), Peak-Twist (7.94 ± 4.280 vs 18.99 ± 4.280; p<0.001), and Torsion (1.01 ± 0.560 vs 2.42 ± 0.600; p<0.001) and decreased in both the preserved EF group and the control group: Peak-AR (6.63 ± 2.49 vs 10.41 ± 3.06, p<0.05), Peak-BR (-5.02 ± 3,040 vs -8.97 ± 2.750; p<0.05), Peak-Twist (10.96 ± 4,740 vs 18.99 ± 4,280, p<0.05), Torsion (1.46 ± 0.600 vs 2.42 ± 0.600, p<0.05). The absolute value of left ventricular torsion parameters gradually decreased from heart failure with EF 50% to heart failure with a slight decrease in ejection fraction to heart failure with EF 40%. From the group of heart failure with grade I diastolic dysfunction to the group of heart failure with grade III diastolic dysfunction, the absolute value of the parameters of left ventricular torsion decreased statistically significantly. Apical rotation and left ventricular torsion have a moderate relationship with EF, left ventricular longitudinal strain as measured by 2D speckle tracking echocardiography. On 2D speckle tracking echocardiography, the angle of rotation should be weakly correlated with EF and left ventricular longitudinal strain drived from 2D speckle tracking echocardiography (2D–GLPS). Conclusion: Torsional deformation parameters of the left ventricle were lower in heart failure patients compared to controls, and they changed earlier in the group with preserved ejection fraction. Torsion deformation parameters, despite being the last variable parameter, are still quite sensitive in detecting left ventricular dysfunction.

Objective: To investigate the clinical and paraclinical characteristics and electrophysiological features after cardioversion in patients with persistent atrial fibrillation (AF). Subejct and method: This was a prospective study of 40 patients with persistent AF who underwent catheter ablation of AF using a three-dimensional (3D) system at the Vietnam Heart Institute, Bach Mai Hospital. Result: The mean age of the patients was 54.25 ± 12.54 years, and 80% of patients were male, the symptoms (according to EHRA) of patients ranged from grade IIb (67.5%) to grade III (32.5%). Hypertension (42.5%) and alcohol abuse (37.5%) were the most common risk factors. After cardioversion, patients with persistent AF exhibited longer sinus node recovery time (SNRT) (1445.11 ± 547.33ms) and corrected SNRT (667.03 ± 517.21ms) than healthy controls. Conclusion: Persistent AF is common in the elderly, especially men, with prevalent risk factors, such as hypertension and alcohol abuse. After cardioversion, patients with persistent AF have an SNRT longer than normal.

Published: March 2023

As the rubber industry turns its focus to sustainability, recovered carbon black (rCB) has emerged as a commercial candidate to replace conventional fossil-based fillers. Since rCB is a new class of rubber filler, much is still to be understood regarding which of its properties influence final applications performance. The research presented in this paper demonstrates the importance of controlling the aggregate size distribution, silica content, carbonaceous residue content, and organic residue content in producing a consistent rCB product. These parameters are also demonstrated to be the fundamental reasons behind the disparity in performance of rCB and carbon black of similar colloidal properties. The findings of this study also reveal that the properties of an rCB can be tailored for a given application with precise control of the process conditions.

Authors: D.I. Chude , N.P. Chude
Published: March 2023

The broad objective of this study is to examine the influence of an ethical environment on managers’ opportunistic behaviour. The study specifically addressed the following, the influence of the ethical environment on the reliability and quality of financial information, the influence of the ethical environment on managers’ responsibility for corporate actions and whether a corporate ethical culture can boost investor confidence in the financial activities of the company. This study utilised a survey research design and the sample comprised ninety-four employees from selected firms. The data were analysed descriptively and the t-test was used to test the hypotheses. The analytical results showed that the ethical environment influences the reliability and quality of financial information; it also influences managers’ responsibility for corporate actions. Lastly, corporate ethical culture can boost investor confidence in the financial activities of the company. Based on this, the study recommends that corporations should create an ethical culture that encourages all corporate governance participants including directors, officers, auditors, financial advisors, employees, and others to do the right thing and understand that this is vital to the company’s sustainable financial performance. The promotion of ethics in accounting professions remains critical for maintaining high standards. The use of judiciary orders to discover, trace and freeze benefits accruing from bad conduct should be possible. There is a need for stricter monitoring of stockbrokers to ensure that depositors’ funds are protected. Investors should be enlightened on their rights and encouraged to seek redress where their rights have been violated.

Human activities more and more intensify the imbalance of aquatic systems causing the reduction of biodiversity. The aim of the study was to identify the microalgae and to determine their distribution in the Mezam River (Bamenda, Cameroon). Sampling took place monthly from July 2021 to August 2022 using plankton net for phytoplankton and scrubbing for periphyton upstream, middle, and downstream of the river. SpeciAJENSR_O9H3LUP0es richness of microalgae amounts to 11 classes divided into 45 genera and 75 species. The most represented class was Bacillariophyceae with 42.67% and the dominant family was the Naviculaceae in terms of abundance with 10 species. Shannon-Weaver diversity index ranges from 2.055 (downstream) to 1.313 (upstream). Spatio-temporal variation of genera revealed 3 groups; group 1 brings together the genera exclusive to phytoplankton, upstream: Pleurotaenium, Synechocystis, Microcystis, and Phormidium. Group 2 brings together the genera exclusive to epiphyte, middle: Encyonema, Trachelomonas, Gloeotrichia, Aphanizomenon, and Peridinium. Group 3 brings together the common genera in the different habitats: Fragilaria, Gomphonema, Synedra, Coscinodiscus, Navicula, Cyclotella, Cymatopleura, Cymbella, Eunotia, Tabellaria, Gyrosigma, Melosira, Pinnularia, Diatoma, Cocconeis, Thalassiosira, Achnanthidium, Nitzschia, Luticola, Rhopalodia, Euglena, Clostrium, Ulothrix, Cryptomonas, Scenedesmus, Spirogyra, Uronema, Mougeotia, Oedogonium, Calothrix, Nostoc, Rivularia, Oscillatoria and Gymnodinium. These results show that Mezam River has a highly diversified community of diatoms that can be used as bio-indicators of pollution.

Predictive policing in an Australian context: assessing viability and utility
Authors: Birks Daniel , Townsley Michael , Hart Timothy
Published: March 2023

Studies in the United States and Europe have demonstrated that burglary and vehicle crime exhibit consistent patterns, supporting the application of crime prediction techniques to proactively deploy police resources to reduce incidents of crime. Research into whether these techniques are applicable in an Australian context is currently limited. Using crime data from the Queensland Police Service, this study assessed the presence of spatio-temporal patterns in burglary, theft of motor vehicle and theft from motor vehicle offences in three distinct local government areas. After establishing the presence of spatiotemporal clustering, the forecasting performance of two predictive algorithms and a retrospective crime mapping technique was evaluated. Forecasting performance varied across study regions; however, the prediction algorithms performed as well as or better than the retrospective method, while using less data. The next step in evaluating predictive policing within Australia is to consider and design effective tactical responses to prevent crime based on the forecast locations and identified patterns.

Authors:   Faculty of Logistics – International Trade, Hoa Sen University, Ho Chi Minh City, Vietnam, Le Nha D.
Published: March 2023

Agricultural export has contributed greatly to Vietnamese economy over the past decades. Nevertheless, logistics performance and institutional quality have been identified as chronic inhibitors and bottlenecks which hamper the export growth of Vietnam. This paper aimed at investigating whether agricultural export was hindered logistically and institutionally. The considered case was Vietnam and major trading partners in the 2007-2018 period. The panel data analysis with fixed and random effects for the baseline estimation was used. Findings indicated that the agricultural export was positively influenced by income per capita and economic and institutional quality similarity between trading partners. Improved logistics performance may unintentionally cause a short term decrease in agricultural export. Institutional quality needs to be enhanced with substantive and specific contents related to the agricultural sector, which mitigates the institutional inequality between industries and locals in the economy.
