Authors: Rodriguez Benavides Domingo , Ceballos Mina Owen Eli
Published: September 2022

Los análisis de convergencia económica en Colombia han mostrado resultados en distintas direcciones; aportar evidencia para enfocar los esfuerzos de política pública en la reducción de las brechas regionales resulta muy pertinente. Usando como variable de análisis el PIB per cápita de los departamentos y la capital del país en el periodo 2000-2016, este artículo evalúa la hipótesis de convergencia total frente a la presencia de clubes regionales por medio de la prueba de Phillips y Sul (2007). Después de excluir del análisis las principales regiones mineras del país se identifican seis clubes de convergencia departamental y un grupo que diverge. Los resultados sugieren la persistencia de la desigualdad en el conjunto nacional, pero múltiples equilibrios o estados estacionarios por grupos de departamentos.
Income-Inequality Relationship within U.S. Metropolitan Areas 1980—2016
Authors: Seifert Friederike
Published: September 2022

Economic growth might both increase and decrease income inequality, also at the city level. This paper examines the income-inequality relationship within US metropolitan areas and finds that it changes over time. A higher average income per capita level was associated with a lower inequality level in earlier years, but this association vanished later. For the 1980-2000 panel, increases in the average income per capita are associated with decreases in inequality. In contrast, increases in the average income per capita are associated with increases in inequality in the 2006-2016 panel. The obtained results hint at polarization resulting from technological change substituting middle-skill routine tasks.
seguridad alimentaria en la encrucijada de las desigualdades regionales de México
Authors: Torres Torres Felipe , Rojas Martínez Agustín
Published: September 2022

El propósito del presente trabajo es analizar las dimensiones regionales de la seguridad alimentaria, vista como problema estructural del desarrollo en México durante el periodo 2000-2020. La hipótesis es que la apertura comercial implementada en el país bajo un marco de desarrollo económico asimétrico, amplió sus desigualdades socio-territoriales y con ello la brecha de la inseguridad alimentaria. Para investigar este fenómeno, aplicamos los métodos Análisis de Componentes Principales (ACP) y estratificación DaleniusHodges, con los cuales construimos un índice de medición a escalas municipal y regional. Los resultados obtenidos señalan que, visto tanto por número de regiones como de proporción de población, más de la mitad de los mexicanos enfrenta algún grado de inseguridad alimentaria. Revertir esta situación implica desplegar una política alimentaria orientada a recuperar la autosuficiencia en la producción de granos básicos y garantizar el acceso a los alimentos, principalmente mediante el mejoramiento del ingreso entre la población ubicada en los rangos de pobreza y pobreza extrema.

Using spatially resolved Hα emission line maps of star-forming galaxies, we study the spatial distribution of star formation over a wide range in redshift (0.5 ≲ z ≲ 1.7). Our z ∼ 0.5 measurements come from deep Hubble Space Telescope (HST) Wide Field Camera 3 G102 grism spectroscopy obtained as part of the CANDELS Lyα Emission at Reionization Experiment. For star-forming galaxies with log(M
*/M
⊙) ≥ 8.96, the mean Hα effective radius is 1.2 ± 0.1 times larger than that of the stellar continuum, implying inside-out growth via star formation. This measurement agrees within 1σ with those measured at z ∼ 1 and z ∼ 1.7 from the 3D-HST and KMOS3D surveys, respectively, implying no redshift evolution. However, we observe redshift evolution in the stellar mass surface density within 1 kpc (Σ1kpc). Star-forming galaxies at z ∼ 0.5 with a stellar mass of log(M
*/M
⊙) = 9.5 have a ratio of Σ1kpc in Hα relative to their stellar continuum that is lower by (19 ± 2)% compared to z ∼ 1 galaxies. Σ1kpc,Hα
/Σ1kpc,Cont decreases toward higher stellar masses. The majority of the redshift evolution in Σ1kpc,Hα
/Σ1kpc,Cont versus stellar mass stems from the fact that log(Σ1kpc,Hα
) declines twice as much as log(Σ1kpc,Cont) from z ∼ 1 to 0.5 (at a fixed stellar mass of log(M
*/M
⊙) = 9.5). By comparing our results to the TNG50 cosmological magneto-hydrodynamical simulation, we rule out dust as the driver of this evolution. Our results are consistent with inside-out quenching following in the wake of inside-out growth, the former of which drives the significant drop in Σ1kpc,Hα
from z ∼ 1 to z ∼ 0.5.

Published: September 2022

The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight into galaxy formation and early chemical enrichment, but identifying them is difficult. Clustering stellar dynamics in 4D phase space (E, L

) is one method of identifying accreted structure that is currently being utilized in the search for accreted UFDs. We produce 32 simulated stellar halos using particle tagging with the Caterpillar simulation suite and thoroughly test the abilities of different clustering algorithms to recover tidally disrupted UFD remnants. We perform over 10,000 clustering runs, testing seven clustering algorithms, roughly twenty hyperparameter choices per algorithm, and six different types of data sets each with up to 32 simulated samples. Of the seven algorithms, HDBSCAN most consistently balances UFD recovery rates and cluster realness rates. We find that, even in highly idealized cases, the vast majority of clusters found by clustering algorithms do not correspond to real accreted UFD remnants and we can generally only recover 6% of UFDs remnants at best. These results focus exclusively on groups of stars from UFDs, which have weak dynamic signatures compared to the background of other stars. The recoverable UFD remnants are those that accreted recently, z
accretion ≲ 0.5. Based on these results, we make recommendations to help guide the search for dynamically linked clusters of UFD stars in observational data. We find that real clusters generally have higher median energy and J

In this data paper, we present a specimen-based occurrence dataset compiled in the framework of the Conservation of Endemic Central African Trees (ECAT) project with the aim of producing global conservation assessments for the IUCN Red List. The project targets all tree species endemic or sub-endemic to the Central African region comprising the Democratic Republic of the Congo (DR Congo), Rwanda, and Burundi. The dataset contains 6361 plant collection records with occurrences of 8910 specimens from 337 taxa belonging to 153 genera in 52 families. Many of these tree taxa have restricted geographic ranges and are only known from a small number of herbarium specimens. As assessments for such taxa can be compromised by inadequate data, we transcribed and geo-referenced specimen label information to obtain a more accurate and complete locality dataset. All specimen data were manually cleaned and verified by botanical experts, resulting in improved data quality and consistency.

The current randomized controlled trial investigated the effect of a robotic pet on social and physical frailty in community-dwelling older adults. The intervention group (
n
= 107) received a robotic pet and the control group (
n
= 113) received usual care following hospital discharge. Social and physical frailty were measured using the Questionnaire to Define Social Frailty Status and the FRAIL questionnaire. Cognitive function and depression were assessed using the Short Portable Mental Status Questionnaire and Geriatric Depression Scale, respectively. Continuous outcomes were compared between groups using
t
tests or Wilcoxon rank sum tests, as appropriate. Categorical outcomes were compared between groups using chi-square tests or Fisher's exact tests, as appropriate. Main findings showed the robotic pet positively impacted cognitive status in participants who reported they enjoyed engaging with their pet. This finding supported the theoretical premise of the current study that greater engagement with the robotic pet would yield greater improvement in study outcomes. [

New application of MOL-PACT for simulating buoyancy convection of a copper-water nanofluid in a square enclosure containing an insulated obstacle
Authors: Alsharari Fahad , Mousa Mohamed M.
Published: September 2022

In this study, we have simulated transient and steady state free convection flow and heat transfer inside a square enclosure filled with a copper-water nanofluid of spherical shape nanoparticles following Tiwari-Das model. The cavity containing an insulated rectangular obstacle of height ranging from 0% to 50% of the cavity side-length. The vertical sides of the enclosure are kept at different temperatures, while the flat sides are assumed to be adiabatic as the obstacle. The combined method of lines/penalty-artificial compressibility technique (MOL-PACT) has been applied to solve the dimensional time dependent mathematical model after converting it into a non-dimensional structure. The combined method of lines/penalty-artificial compressibility technique is recently successfully applied to simulate free convection of MHD fluid in square enclosure with a localized heating. The extension of this promising technique for studying heat transfer of nanofluids is one of the objectives of this paper. Another objective of the study is to inspect the impact of several model parameters such as, the obstacle height, nanoparticles volume-fraction, nanoparticles radius and Rayleigh number on streamlines, temperature distribution and Nusselt number as an expression of heat transfer inside the enclosure. The results have been discussed and shown graphically. Comparisons with former results for related cases in the literature are made and reasonably good agreements are observed.

Authors: Raza Zahid , Singh Akhilesh Kumar
Published: September 2022

Supply chain management (SCM) applications are being developed using blockchain technologies (BCT). This work proposes a blockchain and IoT-based supply chain system (BITS) framework to help create permanent records using smart contracts that can be shared and acted across a product supply chain in the SCM in a decentralized fashion. BITS ensures improved trust, security, transparency, and traceability among the participants aided with BCT and IoT. A demonstration of the data flow and the conceptual illustration of BITS is presented. Algorithms for node authorization and verification based on threshold values are presented. The framework has been rigorously tested for performance considering increasing malicious nodes and over various performance evaluation determining factors (i.e., computational power, memory consumption, time delay, and stability analysis based on the block arrival rate). BITS was evaluated by comparing its performance with consensus algorithm peers (i.e., PoW, PoS, and DPoS). Simulation study reveals the efficient performance of BITS under various test conditions.
Preservice and In-Service EFL Teachers' Assessment Preferences
Authors: Hafour Marwa F.
Published: September 2022

In an authentic class experience, preservice (N = 54) and in-service (N = 65) EFL teachers were assigned digitized formative assessment tasks, and their preferences were assessed using an assessment preferences questionnaire, with both open- and closed-ended questions. Following the pretest-posttest mixed-method design, data were collected and analyzed both qualitatively and quantitatively. Quantitative findings revealed that, though the variety of their preferences increased, both groups had similar preferences after the intervention. Thematic analysis of their responses showed that most preservice and in-service teachers preferred online assessment methods to traditional and formative ones. With respect to the reasons they mentioned for selecting or avoiding a particular method, in-service teachers tended to be more practical and time-oriented than preservice ones, who were more precautious about the intricacies of preparing, responding, and reviewing the assessment task. Both groups also shared a number of emotional reasons and even prioritized them over all the other reasons.

To explore and examine the role of social media as a tool for professional learning within teacher preparation, this qualitative case study examined 73 preservice teachers' observations of literacy teaching on Twitter. Findings indicate that visual posts enhanced teaching strategies and lesson ideas, posts influenced beliefs about teaching and connections to practice, and observations increased enthusiasm toward becoming a teacher. Attention was given to students learning in-action. Reflections emphasize what to teach using a specific strategy or idea. Findings imply that expanding professional learning networks to digital spaces can cultivate teacher knowledge, foster creative teaching practices, and enhance self-critique.
Classroom Behavior Analysis and Evaluation in Physical Education by Using Structure Representation
Authors: Yu Qiufen , Liu Baishan
Published: September 2022

Behavior analysis plays a critical role in physical education. This paper resorts to computer vision technology to establish a classroom behavior analysis system for physical education. First, the behavior video is collected by a Kinect camera. Then, the behavior is recognized based on the symbiotic relationship and geometric constraints between human posture and interactive objects. The human skeleton is used to describe the behavior subject and the local area boundary boxes are divided with each node in the skeleton as the center. The human posture features are used to learn a structural classification model to recognize human behavior sequence. Finally, the behavior recognition results are used to analyze physical education. The experimental results show that the proposed behavior analysis framework can accurately recognize human behavior during physical education classes.

Published: September 2022

The main purpose of this study is to reveal the impact of consumer satisfaction on continuance intention to use wearable fitness devices. Building upon the IS Continuance Intention Model, the authors explored the effects of confirmation of ease of use, confirmation of perceived usefulness, positive and negative feelings, and perceived control on consumer satisfaction. The effects of health motivation and social influence on continuance intention were examined alongside satisfaction. Our model consists of twelve constructs and eleven hypotheses. An online survey was conducted among 216 Amazon M-Turk workers to collect data. The measurement model was first tested and validated. Next, structural equation modeling was used to test the hypotheses in the research model. Nine out of eleven hypotheses were supported. The model explains 50.1% of variances in continuance intention, and 63.9% of variance in consumer satisfaction is explained by the aforementioned factors. Both theoretical contributions and practical implications are discussed in the context of wearable technology.

Indian healthcare is described as the largest sector, both in revenue and employment. The quality of service—the characteristics that shape care experience beyond technical competence—is rarely discussed in the medical literature. This study reveals the determinants that affect the perception of quality of healthcare services from the patients' and service providers' points of view. A cross-sectional method was followed to determine the perception of quality of healthcare services and relating variables including infrastructure, reliability and responsiveness, empathy, affordability, and administration. The data collected from 400 respondents, including patients and service providers, for the study were analyzed using confirmatory factor analysis. Results confirmed that healthcare service quality aspects (i.e., physical environment, staff behavior, responsiveness, affordable services, admission process) positively relate to customers' perception. Findings will help the hospital managers articulate effective strategies to ensure superior quality of healthcare services to customers.

Published: September 2022

During this pandemic outbreak of COVID-19, the whole world is getting severely affected in respect of population health and economy. This novel virus has brought the whole world including the most developed countries to a standstill in a very short span like never before. The prime reason for this unexpected outburst of COVID-19 is lack of effective medicine and lack of proper understanding of the influencing factors. Here, the authors aim to find the effect of epidemiological factors that influence its spread using a fuzzy approach. For the same, a total of nine factors have been considered which are classified into risk and preventive factors. This fuzzy model supports to understand and evaluate the impact of these factors on the spread of COVID-19. Also, the model establishes a basis for understanding the effect of risk factors on preventive factors and vice versa. It is worth mentioning that this is the first attempt to analyze the effect of clinical and epidemiological factors with respect to COVID-19 using a fuzzy approach.

Volatility Analysis in International Indices
Authors: Altin Hakan
Published: September 2022

Modeling and the estimation of volatility in financial time series are important research subjects for which ARCH family models are recommended. These models are widely used to analyze volatility and manage risk in financial assets. In this study, share indices from the BRIC countries, Europe and the United States were analyzed to determine volatility in international indices. Current data was used to examine the period 1982-2021. Within this framework, the existence of asymmetric information, the leverage effect and the permanence of shocks were examined. Estimation results show the existence of asymmetric information. Bad news affects the system more than good news. The leverage effect is also experienced. Estimation results show that the shocks affecting the system are permanent. At the last stage, static foresight estimations were conducted on the explanatory power of the estimation results. Static foresight estimations present strong and weak evidence together. All parameters are statistically significant.

Engagement in international trade and investment affects the attainment of macroeconomic objective of a nation. The purpose of this research was to assess the effect of international trade and investment on economic growth of Bangladesh measured by GDP, GDP growth, per capita income, unemployment rate, and capital investment. Type of data was secondary, and nature of data was time series. Study period was from 2000-2018. Ordinary least square regression has been applied to explore the impact. The study showed that exchange rate significantly positively impacts, but foreign remittances significantly negatively impact GDP, per capita income, and capital investment. GDP growth is significantly influenced only by exchange rate, and international trade and investment have an insignificant impact on unemployment. The findings of the study are beneficial for national economic and industrial policymakers, government, ministry of commerce and industry, and Bangladesh Bank as formulating appropriate policy regarding exchange rate and foreign remittance could contribute to Bangladesh's economic growth.
Exploring Business Ecosystem Dynamics Using Agile Structuration Theory
Authors: Beckett Ronald C. , O'Loughlin Andrew
Published: September 2022

The authors' background interest is in innovation and entrepreneurship as elements of business strategy.  Business ecosystems are viewed as complex adaptive systems, and engagement with such systems is explored utilising an analytical technique  based on an agile structuration theory model.  In this model, motivated knowledgeable agents act within an institutional (structuration) framework to implement a business idea, drawing on accessible resources from a broader business ecosystem and then learn from the outcomes. In a particular instance, this learning may lead to enhanced agent absorptive capacity, to an adaptation of an institutional framework, and to enhanced ecosystem resources that may be built on in another instance. Formal and informal interaction across boundaries is seen as important in accessing a broader socio-economic ecosystem which may be time-place sensitive. Longitudinal studies of one business model innovation and one technological innovation case, both embedded in the same regional business ecosystem, provide an illustration of the model's application.

Published: September 2022

'Hearables' have become important in the aging population. This study investigates whether smart technologies help middle-aged and elderly people accept hearing aid devices in smart cities of China. The authors adopt the PLS-SEM framework to analyze the factors that affect behavioral intention towards adopting hearing aids in smart cities. In order to avoid common method bias, Harman's single factor method is also carried out to make sure the instrument does not introduce a bias. The findings suggest that perceived playfulness and perceived usefulness are principal determinants of hearing aids adoption. In contrast, perceived ease of use, a factor always stressed in literature, does not matter significantly. The results reveal that smart technologies enable patients to access professional services and instructions playfully, which reduces obstacles to adopt hearing aids. This study provides novel insights for policymakers and manufacturers to expand hearing aid adoption by facilitating smart infrastructure and technologies.

Trichilemmal cysts constitute the second most common cutaneous cysts and are mostly presented on the scalp of middle aged women. It is, therefore, unusual for a young person to have a trichilemmal cyst and it is extremely rare for a trichilemmal cyst to be ossified. In literature, only 8 cases of trichilemmal cysts with concomitant ossification have been described. We report the case of a 22 year old female who presented with a scalp nodule and was treated via surgical excision of the lesion. The pathology examination of the surgical specimen revealed a lesion consisting of a multilayered squamous epithelium of slightly eosinophilic maturing keratinocytes. There was no granular layer, whereas the core of the lesion was occupied by mature bone tissue with calcium deposits. The definite diagnosis of the pathology report was ossifying trichilemmal cyst. The aim of this report is, to enlighten clinicians about this rare pathological entity.

In multiple sclerosis patients (MS), symptoms such as fatigue, lack of physical energy, spasticity, motor coordination disorders, tremors, dizziness and postural instability are most common. Cattaneo et al. (2007) studied the effects of stability training on MS patients, describing its efficacy in reducing all risks, by improving stability, and strength. The present study aimed to confirm our 2021 results on MS patients, combining the Taopatch® device with a proprioceptive rehabilitation protocol (PRP) targeting strength, balance, and biochemical parameters including vitamin D levels. Twenty MS patients, 8 males and 12 females, volunteered in the study. A KERN MAP Version 1.2 08/2012, Hand Grip Dynamometer was used to determine handgrip strength, whilst baropodometric and stabilometric measurements were assessed using the Sensor Medica® systems. The proprioceptive rehabilitation protocol included: 10 minutes of Motomed; 10 minutes of Human Tecar proprioceptive path; 15 minutes of physical exercises; and 15 minutes of massage therapy of whole spine. All patients wore the Taopatch photo emission devices (Tao Technologies), applied with the protocol of Carbonari B, et al. (2021) Testing procedures and blood sampling were carried out before and after the rehabilitation protocol. The paired sample t-test revealed statistically significant improvements for the baropodometric measures (p<0.05). In addition, the intervention induced a statistically significant improvement in the right (p = 0.023) and left (p = 0.021) handgrip strength. We didn’t highlighted any statistically significant variation in hemathological parameters, but an increasing trend of vitamin D levels was detected. Combination of an adequate and specific rehabilitation protocol with application of Taopatch®, a photon emission device, improved handgrip strength of the upper limbs, rebalanced body structure decompensated in MS patients and also acting on vitamin D levels. In conclusion, Taopatch® is a supportive therapy for home-based PRP intervention, inducing an improvement in the quality of life and reducing spasticity associated with the disease.
When the judiciary disbelieves the victim: Stereotypes and their influence on assessments of the credibility of victims of sexual abuse – a case study
Authors: Wojciechowska Małgorzata
Published: September 2022

This paper addresses the psychological assessment of victims and the credibility of their statements in cases of child sexual abuse. With reference to the presence of manifestations of stress and to how victims behave when giving a statement, it discusses issues associated with assessment in such cases. It then considers existing inventories of possible physical and psychological consequences of sexual abuse and the frequency of PTSD symptoms among victims, before examining how these manifestations are modified by the context of the abuse, the characteristics of the offender, the characteristics of the victim, and how those in the victims’ life contexts react to disclosure of the abuse. Finally, the paper presents a case study illustrating these issues.
