Published: September 2022

Aim: To carry out the comparative analysis of the indicators of working capacity (physical and mental) of law enforcement officers in the conditions of educational process and service activities.
Materials and Methods: The research of physical working capacity was carried out using the Harvard step test and mental working capacity was assessed by means of the correction test. The cadets (n=72) who studied at the higher educational institution for 3 years (2017-2021) and served in the practical police units after the training were involved in the testing. The testing was carried out in 3 stages: 1st – the beginning of the first training year (2017); 2nd – the end of the third training year (2020); 3rd – after 1 year of service (2021).
Results: Significant (p 0.05) deterioration after 1 year of their service (by 1.9 % and 5.4 % respectively) was established.
Conclusions: It was found that the organization of the educational process in higher educational institutions is quite effective in improving both physical and mental working capacity of future law enforcement officers. However, the decrease of their working capacity after 1 year of service indicates the complexity and extremity of service activities in practical units.

Authors: Mwandembwa Tumaini C. , Matiku Emmanuel
Published: September 2022

The advancement of science and technology has caused a revolution in procurement processes among public organisations worldwide. The purpose of the study was to examine the influence of e-procurement on ethical conduct improvement in Mzinga Corporation. The case study design was employed to collect qualitative data from the departments of procurement, stores, ICT, and Human Resource Management in Mzinga Corporation. A total of 45 participants were involved in interviews and Focus Group Discussions. Data analysis involved thematic analysis. The findings of the study showed that the use of e-procurement has an influence on employee ethical conduct. E-procurement, unethical conduct such as reduced collusion and corruption, having a single platform for all procurement activities and all specifications are open in the procurement system. All these reduced unethical conduct related to corruption and theft. Furthermore, it was found by the study that the use of e-procurement had reduced conflicts through strengthening relationships, observing equality and equity for bidders/suppliers, and reducing bureaucratic complexities. It was concluded that e-procurement is an important tool and a platform that links the pool of suppliers with public organisations. Mzinga Corporation has ethical standards to guide the employees to act ethically and one of the benefits of e-procurement is that it can control the behaviour of the employees in the public service. It is recommended that the procurement system should be open and accessible to all employees so as to strengthen participation and inclusion for the best of the institution in managing the resources.
Efectos de los factores demográficos y de la felicidad laboral sobre la productividad académica investigativa
Authors: Ramírez Pérez Martha Elena , Ontiveros Ramírez Flor , Del Valle López Jair Arody
Published: September 2022

La felicidad laboral es una prioridad a nivel personal y empresarial, incluyendo el ámbito educativo. Se dice que los trabajadores con un alto nivel de felicidad son más productivos, por lo cual este estudio tuvo como objetivo determinar si el nivel de felicidad laboral es predictor significativo del grado de productividad académica investigativa en docentes de una universidad del noreste de México.

El constructo nivel de felicidad laboral obtuvo una buena confiabilidad (α = .852). En cuanto al constructo grado de productividad académica investigativa, el cual fue considerado unidimensional, obtuvo una confiabilidad aceptable (α = .771).

Las técnicas estadísticas utilizadas fueron ANOVA general, ANCOVA y regresión lineal simple.

Se encontró que los actores demográficos edad y grado académico y las interacciones género * edad y género * grado académico tienen un efecto sobre el grado de productividad académica investigativa (F(23, 70) = 4.027, p = .000, n2p = .668).

Se consiguió evidencia de que el nivel de felicidad laboral, como covariable, no tiene un efecto significativo sobre las diferencias de medias aritméticas de la autopercepción del grado de productividad académica investigativa en función de las poblaciones definidas por los niveles de respuesta de los factores demográficos (F(1, 69) = 2.550, p = .117, n2p = .054).

Se halló que el nivel de felicidad laboral, aunque es un predictor significativo, solo explica el 7% de la varianza del grado de productividad académica investigativa (F(1,70) = 5.340, p = .024, R2 = .071, f2 = .185, 1-b = 0.95, n = 72).
¿Es Wikipedia una fuente de información confiable? La multitud responde
Authors: Rodríguez Antonio Raúl
Published: September 2022

A pesar de su popularidad, citar a Wikipedia en un trabajo académico es una práctica generalmente no aceptada por docentes e investigadores. La principal razón argumentada a este respecto es también la característica distintiva de Wikipedia: ser una enciclopedia libre donde cualquier persona, sin importar su nivel de erudición, puede escribir contenidos. En primera instancia, esta cualidad supondría que sus contenidos son de inferior calidad y confiabilidad con relación a las enciclopedias tradicionales, que cuentan con el respaldo de un equipo editorial experto. Problemas tales como editores amateurs, volatilidad de contenidos y vandalismo se argumentan como factores que desacreditan la confiabilidad de Wikipedia. En este trabajo se discute el fenómeno de la sabiduría de las multitudes como el fundamento de la confiabilidad de Wikipedia, lo que, aunado a sus características epistemológicas, la posicionan como una fuente de conocimiento digna de ser consultada por estudiantes y docentes.

The Predictive Role Of Cognitive Flexibility And Cognitive Control On Aggression and Anger İn Sports
Authors: YAZICI Ömer Faruk , MERGAN Barış
Published: September 2022

At the time of competition, athletes experience instant emotional change and stress in the face of both adaptation and change demands. Therefore, athletes need skills such as cognitive control and cognitive flexibility to control their aggression and anger during stress while competing. From this point of view, the research aims to determine the role of cognitive control over emotions, evaluation and coping flexibility in aggression and anger in sports and to examine their relationships according to some variables. The study group of the research consists of a total of 442 athletes, 205 females (46.4%) and 237 males (53.6%). "Competitive Aggressiveness and Anger Scale" and "Cognitive Control and Flexibility Scale" were used in the research. Descriptive statistics, MANOVA Test and Multiple Linear Regression (MLR) were used for data analysis. In the findings of the research, it was seen that the aggression mean scores of males were high, and anger and aggression mean scores were higher in athletes who smokes and used alcohol. Another important result of the study is that cognitive control over emotions and evaluation and coping flexibility explain 17% of the total variance in aggression and anger in sports. In particular, it can be said that cognitive control over emotions has a higher effect on determining aggression and anger in sports.
Change and Continuity in Quality of Government:
Authors: Charron Nicholas , Lapuente Víctor , Bauhr Monika , Annoni Paola
Published: September 2022

Despite massive investments, studies suggest that anticorruption efforts often times fail and that countries and regions with historically deficient quality of government tend to be stuck in a vicious cycle of high levels of corruption and inadequate public service delivery. However, this study suggests that despite the stickiness of subnational quality of government, regional quality of government does shift over time. Using the 2021 European Quality of Government Index (EQI), and comparing the results to previous rounds of this survey, we show that there has indeed been noticeable shifts in the regional level of Quality of Government both within countries and across time. Overall, we find a slight increase in the perceived quality of government of European regions compared with 2017. However, some regions have evaded the positive trend, most notably in Poland and Hungary, whose response to the pandemic – probably not coincidentally – has involved important infringements of democratic rights and institutions. These changes in Quality of government call for a close mapping of the trends within countries and across regions and a focus on their determinants. To this end, the paper also serves as an introduction to the use of 2021 European Quality of Government (EQI) index, which is the most comprehensive survey to date to measure perceptions of subnational quality of government with a total of 129,000 respondents in 208 NUTS 1 and NUTS 2 regions and all EU 27-member state countries.
Actions fostering adoption of Industry 4.0 technologies in manufacturing companies in European regions
Authors: Dyba Wojciech , Di Maria Eleonora , Chiarvesio Maria
Published: September 2022

Industry 4.0, a concept comprising a range of promising innovations enabled by the recent advancements in digital technologies, has become a priority of industrial policy in many European countries and regions. In this paper we present actions undertaken by regional organisations (including the so called Digital Innovation Hubs), fostering adoption of Industry 4.0 technologies in manufacturing companies. Using examples from Germany, Italy and Poland, we show actions that both allow to create general conditions for such implementations, but also help individual companies to create individual strategy for adopting Industry 4.0 innovations.
Inferred Properties of Planets in Mean-motion Resonances are Biased by Measurement Noise
Authors: Jensen David , Millholland Sarah C.
Published: September 2022

Planetary systems with mean-motion resonances hold special value in terms of their dynamical complexity and their capacity to constrain planet formation and migration histories. The key toward making these connections, however, is to have a reliable characterization of the resonant dynamics, especially the so-called “libration amplitude,” which qualitatively measures how deep the system is into the resonance. In this work, we identify an important complication with the interpretation of libration amplitude estimates from observational data of resonant systems. Specifically, we show that measurement noise causes inferences of the libration amplitude to be systematically biased to larger values, with noisier data yielding a larger bias. We demonstrated this through multiple approaches, including using dynamical fits of synthetic radial velocity data to explore how the libration amplitude distribution inferred from the posterior parameter distribution varies with the degree of measurement noise. We find that even modest levels of noise still result in a slight bias. The origin of the bias stems from the topology of the resonant phase space and the fact that the available phase-space volume increases nonuniformly with increasing libration amplitude. We highlight strategies for mitigating the bias through the usage of particular priors. Our results imply that many known resonant systems are likely deeper in resonance than previously appreciated.

The rest are evenly distributed as incidental and transient irregulars or spheroids. These fractions are roughly independent of redshift and stellar mass up to ∼1010

at z > 4 form at initial peaks of the matter-density field. Large-scale structures in the universe emerge and grow like cosmic rhizomes as the underlying matter-density fluctuations grow and form associations of galaxies in rare overdense regions and the realm of the galactic world is stretched into relatively lower-density regions along evolving filaments. The cosmic web of galaxies forms at lower redshifts when most rhizomes globally percolate. The primordial angular momentum produced by the induced tidal torques on protogalactic regions is correlated with the internal kinematics of galaxies and tightly aligned with the angular momentum of the total galaxy mass. The large-scale tidal field imprinted in the initial conditions seems responsible for the dominance of disk morphology and for the tendency of galaxies to reacquire a disk postdistortion.
Reconstruction of Coronal Magnetic Fields Using a Poloidal–Toroidal Representation
Authors: Yi Sibaek , Choe G. S. , Cho Kyung-Suk , Solanki Sami K. , Büchner Jörg
Published: September 2022

A new method for reconstruction of coronal magnetic fields as force-free fields (FFFs) is presented. Our method employs poloidal and toroidal functions to describe divergence-free magnetic fields. This magnetic field representation naturally enables us to implement the boundary conditions at the photospheric boundary, i.e., the normal magnetic field and the normal current density there, in a straightforward manner. At the upper boundary of the corona, a source surface condition can be employed, which accommodates magnetic flux imbalance at the bottom boundary. Although our iteration algorithm is inspired by extant variational methods, it is nonvariational and requires far fewer iteration steps than most others. The computational code based on our new method is tested against the analytical FFF solutions by Titov & Démoulin. It is found to excel in reproducing a tightly wound flux rope, a bald patch, and quasi-separatrix layers with a hyperbolic flux tube.

Authors: Alkhalidi Emad Farhan , Ahmad Zena A.
Published: September 2022

AIM: The aim of this in vitro study is to determine the push-out bond strength of bundle glass fiber post (Rebilda GT) and tapered glass fiber post (Rebilda fiber post).

MATERIALS AND METHODS: Twenty freshly extracted human single rooted premolar teeth were used, all teeth were endodontically treated, after 24 h from obturation the gutta-percha removed leaving 5 mm apically to ensure clinically acceptable apical seal. Finally, all canals were flushed with 2 ml NaOcl 5.25% and 2 ml distilled water, respectively, then the canals were dried using paper points. The roots were divided randomly into two sets with ten roots for each group according to post-type. Group A: Rebilda fiber posts were used. Group B: Rebilda GT bundle fiber posts were used. The posts were inserted into the canals according to the manufacturer instructions. All specimens were stored for 72 h in an incubator. Slices of 2 mm thickness were cut from the roots at different levels (cervical, middle, and apical thirds), bond strength was determined using universal testing machine at a speed of 0.5 mm/min.

RESULTS: One-way analysis of variance and Tukey HSD tests showed that the (bundle fiber) Rebilda GT fiber post had bond strength higher than that of the Rebilda fiber post in all regions. (p < 0.05), also the cervical area showed higher bond strength in both groups than the middle and the apical areas, respectively.

CONCLUSIONS: The bundle glass fiber post (Rebilda GT) showed bond strength higher than the taper glass fiber (Rebilda fiber) post in all regions (apical, middle, and cervical). The cervical region showed higher bond strength than the middle and the apical thirds.
Adalimumab Biosimilar Efficacy and Safety in a 5-Year-Old Patient with Severe Plaque Psoriasis During SARS-CoV-2 Pandemic Outbreak
Authors: Gallo Lucia , Capasso Gianmarco , Nastro Francesca , Fabbrocini Gabriella , Megna Matteo
Published: September 2022

BACKGROUND: Psoriasis is a chronic inflammatory disease that affects 2% of population. About 0.5–2% of psoriatic cases develop during pediatric age. In most cases, the condition is responsive to topical treatment. However, a small percentage of children require systemic treatment with conventional systemic drugs or biological agents, such as anti-tumor necrosis factor (TNF)-α. Adalimumab (ADA) is an anti-TNF-α recently approved for pediatric psoriasis in the European Union (from 4 years of age, 2015).

CASE PRESENTATION: We describe our experience treating a 5-year-old female patient affected by severe plaque psoriasis with ADA biosimilar during SARS-CoV-2 pandemic outbreak also using teledermatology.

CONCLUSION: The case reported in this article highlights the safety and the effectiveness of ADA biosimilar MSB11022 (Idacio®) in the treatment of a 5-year-old female affected by plaque psoriasis and paves the way to bigger trials for a more extensive use of TNF-α inhibitor biosimilars for psoriasis in pediatric population.
From Biodiversity Observation Networks to Datasets and Workflows Supporting Biodiversity Indicators, a French Biodiversity Observation Network (BON) Essential Biodiversity Variables (EBV) Operationalization Pilot using Galaxy and Ecological Metadata Language

Published: September 2022

Integration of biological data with different ecological scales is complex! The biodiversity community (scientists, policy makers, managers, citizen, NGOs) needs to build a framework of harmonized and interoperable data from raw, heterogeneous and scattered datasets. Such a framework will help observation, measurement and understanding of the spatio-temporal dynamic of biodiversity from local to global scales. One of the most relevant approaches to reach that aim is the concept of Essential Biodiversity Variables (EBV). As we can potentially extract a lot of information from raw datasets sampled at different ecological scales, the EBV concept represents a useful leverage for identifying appropriate data to be collated as well as associated analytical workflows for processing these data.

Thanks to FAIR data and source code implementation (Findable, Accessible, Interoperability, Reusable), it is possible to make a transparent assessment of biodiversity by generating operational biodiversity indicators (that can be reused / declined) through the EBV framework, and help designing or improving biodiversity monitoring at various scales.

Through the BiodiFAIRse GO FAIR implementation network, we established how ecological and environmental sciences can benefit from existing open standards, tools and platforms used by European, Australian and United States infrastructures, particularly regarding the Galaxy platform for code sources accessiblility and the DataOne network of data catalogs and the Ecological Metadata Language standard for data management. We propose that these implementation choices can help fight the biodiversity crisis by supporting the important mission of GEO BON (Group on Earth Observation Biodiversity Observation Network): “Improve the acquisition, coordination and delivery of biodiversity observations and related services to users including decision makers and the scientific community” (GEO BON 2022).
A case of frozen behaviour: A flat wasp female with a beetle larva in its grasp in 100-million-year-old amber

Published: September 2022

Parasitism, a malignant form of symbiosis, wherein one partner, the parasite, derives benefits to the detriment of another, the host, is a widespread phenomenon. Parasitism sensu lato is understood here to include many phenomena, like parasitoidism, kleptoparasitism, phoresy and obligate parasitism. Insecta has many in-groups that have evolved a parasitic life-style; one of the largest in-groups of these is probably the group of Hymenoptera. Bethylidae, the group of flat wasps, is a smaller in-group of Aculeata, the group of hymenopterans with venom stings; representatives of Bethylidae are parasitic. They are more specifically larval ectoparasitoids, meaning that their immature stages are externally developing parasites that kill their host organism at pupation (end of interaction). They mostly parasitise immature representatives of Coleoptera and Lepidoptera. Female flat wasps search for a host for their progeny, paralyse it with their venom sting and then oviposit onto it.

Herein we describe one of the oldest findings of parasitic interactions of parasitoid wasps with their progenies’ hosts, specifically a flat wasp female grasping and (potentially) stinging a beetle immature in Cretaceous Kachin (Myanmar) amber (ca. 100 million years old). This finding indicates that this type of parasitic interaction existed since the Cretaceous, temporally close to the earliest findings of representatives of Bethylidae.
Urban ecosystems and heavy rainfall – A Flood Regulating Ecosystem Service modelling approach for extreme events on the local scale
Authors: Wübbelmann Thea , Bouwer Laurens , Förster Kristian , Bender Steffen , Burkhard Benjamin
Published: September 2022

Increasing urbanisation in combination with a rise in the frequency and intensity of heavy rain events increase the risk of urban flooding. Flood Regulating Ecosystem Services (FRES) address the capacity of ecosystems to reduce the flood hazard and lower damage. FRES can be estimated by quantification of supply (provision of a service by an ecosystem) and demand (need for specific ES by society). However, FRES for pluvial floods in cities have rarely been studied and there is a gap in research and methods on FRES supply and demand quantification.

In this study, we assessed FRES of an urban district in the City of Rostock (Germany) for a one-hour heavy rainfall event using the hydrological model LEAFlood. The hydrological model delivered the FRES supply indicators of soil water retention and water retained by canopies (interception). An intersection of the potential demand (based on indicators of population density, land reference value, monuments and infrastructure) and the modelled surface water depth revealed the actual demand. Comparing the actual demand and supply indicated the budget of FRES to identify unmet demand and supply surplus.

Results show highest mean FRES supply on greened areas of forests, woodlands and green areas, resulting in a supply surplus. Whereas, sealed areas (paved surface where water cannot infiltrate into the soil), such as settlements, urban dense areas, traffic areas and industry, have an unmet demand resulting from low supply and relatively high actual demand.

With the hydrological model LEAFlood, single landscape elements on the urban scale can be evaluated regarding their FRES and interception can be considered. Both are important for FRES assessment in urban areas. In contrast to flood risk maps, the study of FRES gives the opportunity to take into account the contribution of nature to flood regulation benefits for the socio-economic system. The visualisation of FRES supply and demand balance helps urban planners to identify hotspots and reduce potential impacts of urban pluvial flooding with ecosystem-based adaptations.

Chapitre 2. La réglementation en matière de logement social
Authors: Brouant Jean-Philippe
Published: September 2022

Afin de préciser le rôle respectif de chacun dans la « chaîne du logement », on retient traditionnellement trois secteurs d’intervention. Le premier recouvre la programmation du logement, c’est-à-dire à la fois la définition d’objectifs, de priorités et les modalités de réalisation de ces objectifs. Le deuxième secteur d’intervention constitue, d’une façon globale, la réalisation des objectifs en termes de financement. Enfin, au bout de la « chaîne du logement », se trouvent les éléments relatifs à la gestion des logements sociaux, à savoir les politiques de peuplement. Analyser dans le détail la réglementation du logement social et sa mise en œuvre répond à un objectif audacieux. Il impliquerait une enquête lourde sur la mise en œuvre réelle des compétences et les mécanismes qui dépasse les compétences du juriste. L’étude s’est néanmoins appuyée sur l’analyse de certains documents locaux qui permettent de dégager des traits généraux sans prétendre à la fixation de constats définitifs. De plus ont été prises en compte les expériences sur sites menées par les associations régionales HLM.

Yeast are a powerful material for the encapsulation of compounds. Usually, yeast used as capsules are inactivated by the encapsulation treatment, which is stressful to cells. However, if kept active, cells can bring their own activity in addition to the encapsulated compound. We have observed previously that lipid-grown Yarrowia lipolytica were more resistant to encapsulation. The objective of the present study was to identify physiological markers involved in this resistance. Cells were cultured in the presence of glucose or methyl-oleate as the sole carbon source and submitted to a γ-dodecalactone stress. This paper focuses on the role of intracellular lipid droplets (LDs) and of the ergosteryl content to protect cells during the lactone treatment. Lipid-grown cells were more resistant to lactone and the presence of LDs before the shock increased significantly the resistance. The ergosteryl esters from the LD pool were hydrolysed to release ergosterol able to strenghten the plasma membrane during the shock. For cells devoid of LDs, membrane ergosterols were esterified concomitantly with LDs growth, resulting in a membrane weakening. By using pox3-mutant strains, which possesse numerous and small-sized LDs, we observed the original behaviour: these mutants showed no increased resistance and their LDs exploded in the cytoplasma during the shock. These results point out the role of LDs in cell resistance to amphiphilic stresses as a storage compartment as well as in ergosterol homeostasis.
A hybrid algorithm based on parareal and Schwarz waveform relaxation
Authors: Yang Liping , Li Hu
Published: September 2022

In this paper, we present a hybrid algorithm based on parareal and Schwarz waveform relaxation (SWR) for solving time dependent partial differential equations. The parallelism can be simultaneously realized in the time direction by using a parareal and in the space direction via SWR. We give a convergence analysis for the hybrid algorithm for a 1D model problem, the reaction-diffusion equation. Weak scaling of the algorithm in terms of both the number of space subdomains and the number of paralleled time intervals were investigated via theoretical analysis and numerical experiments.

Published: September 2022

A concept of fuzzy projection operator is introduced and use to investigate the non-emptiness of the fuzzy proximal pairs. We then consider the classes of noncyclic contractions and noncyclic relatively nonexpansive mappings and survey the existence of best proximity pairs for such mappings. In the case that the considered mapping is noncyclic relatively nonexpansive, we need a geometric notion of fuzzy proximal normal structure defined on a nonempty and convex pair in a convex fuzzy metric space. We also prove that every nonempty, compact and convex pair of subsets of a strictly convex fuzzy metric space has the fuzzy proximal normal structure.

Red imported fire ants (RIFA) are an alien invasive pest that can cause serious ecosystem damage. Timely detection, location and elimination of RIFA nests can further control the spread of RIFA. In order to accurately locate the RIFA nests, this paper proposes an improved deep learning method of YOLOv4. The specific methods were as follows: 1) We improved GhostBottleNeck (GBN) and replaced the original CSP block of YOLOv4, so as to compress the network scale and reduce the consumption of computing resources. 2) An Efficient Channel Attention (ECA) mechanism was introduced into GBN to enhance the feature extraction ability of the model. 3) We used Equalized Focal Loss to reduce the loss value of background noise. 4) We increased and improved the upsampling operation of YOLOv4 to enhance the understanding of multi-layer semantic features to the whole network. 5) CutMix was added in the model training process to improve the model's ability to identify occluded objects. The parameters of improved YOLOv4 were greatly reduced, and the abilities to locate and extract edge features were enhanced. Meanwhile, we used an unmanned aerial vehicle (UAV) to collect images of RIFA nests with different heights and scenes, and we made the RIFA nests (RIFAN) airspace dataset. On the RIFAN dataset, through qualitative analysis of the evaluation indicators, mean average precision (MAP) of the improved YOLOv4 model reaches 99.26%, which is 5.9% higher than the original algorithm. Moreover, compared with Faster R-CNN, SSD and other algorithms, improved YOLOv4 has achieved excellent results. Finally, we transplanted the model to the embedded device Raspberry Pi 4B and assembled it on the UAV, using the model's lightweight and high-efficiency features to achieve flexible and fast flight detection of RIFA nests.
Runtime verification in uncertain environment based on probabilistic model learning

Published: September 2022

Runtime verification (RV) is a lightweight approach to detecting temporal errors of system at runtime. It confines the verification on observed trajectory which avoids state explosion problem. To predict the future violation, some work proposed the predictive RV which uses the information from models or static analysis. But for software whose models and codes cannot be obtained, or systems running under uncertain environment, these predictive methods cannot take effect. Meanwhile, RV in general takes multi-valued logic as the specification languages, for example the $ true $, $ false $ and $ inconclusive $ in three-valued semantics. They cannot give accurate quantitative description of correctness when $ inconclusive $ is encountered. We in this paper present a RV method which learns probabilistic model of system and environment from history traces and then generates probabilistic runtime monitor to quantitatively predict the satisfaction of temporal property at each runtime state. In this approach, Hidden Markov Model (HMM) is firstly learned and then transformed to Discrete Time Markov Chain (DTMC). To construct incremental monitor, the monitored LTL property is translated into Deterministic Rabin Automaton (DRA). The final probabilistic monitor is obtained by generating the product of DTMC and DRA, and computing the probabilities for each state. With such a method, one can give early warning once the probability of correctness is lower than a pre-defined threshold, and have the chance to do adjustment in advance. The method has been implemented and experimented on real UAS (Unmanned Aerial Vehicle) simulation platform.

Published: September 2022

To be successful, BDA applications must be capable of producing actionable information useful to support managerial decisions throughout the organization. Some authors have proposed that BDA projects differ from IT projects by requiring extra analytical capabilities, special software, and more specialized application developers to enhance decision modelling effectiveness. This study used a two-respondent survey of decision makers using BDA applications fully operational for between 1-3 years and the corresponding CDOs in 282 organizations in various industry sectors. Using stepwise multivariate regression analysis, this convenience sample with a response rate of 32% was used to test hypotheses regarding the importance of some factors proposed in the literature as likely to improve the success of BDA applications. The results corroborate the importance of these factors by explaining a substantial percentage of the variance in decision modelling effectiveness and support several insights on a few success factors corporate managers should focus on.

Authors: Nigam Sucheta , Kapoor Vibha
Published: September 2022

Interior designers own an exceptional ability to engender novel ideas and solutions. It is important to express or convey this idea to clients effectively so that clients can understand the project. Designers and architects validated that they have two ways to express their ideas or communicate with their clients: 2-D and 3-D presentations. Clients have their own experience and perception of these presentations, based on a few elements that they perceive from this presentation. This paper compares 2-D and 3-D presentations, as well as the elements that shape the client's experiences and the propensity towards 2-D and 3-D presentations. The study attempted to investigate a method for perceiving and persuading clients to accept a creative idea without wasting time. The outcomes of the study can be utilized by the designers and institutes to focus more on this skill, as it plays an undeniable role in interior design as it saves them time and money.
