In the South Urals, numerous wells have been found inside dwellings in settlements of the Bronze Age. These features are of great interest, not only because of the artifacts found inside the wells, but also as the first hydrotechnical structures within the territory of northern Eurasia. Geophysical studies were carried out over the area of two Bronze Age settlements: the fortified settlement of Konoplyanka and the unfortified settlement of Konoplyanka 2. A gradient magnetic survey was carried out and settlement plans reconstructed, which formed the basis for the selection of sites for the archaeological excavations. Comparison of geophysical and archaeological results showed that, using magnetic maps, it was possible to accurately reconstruct the plans of ancient settlements and localize the positions of wells. At the excavation site of the settlement of Konoplyanka 1, as a result of the magnetic susceptibility survey, it was established that the edges of the wells were reinforced with a special soil that has higher magnetic properties than the subsoils present. At the excavation site at the settlement of Konoplyanka 2, ground penetrating radar (GPR) prospection of the four wells was carried out, the depth and structural features of these wells being determined. Excavations at two of the wells confirmed the results of the geophysical studies.

Authors: Sathi Sadhana Sruveera , Dugan Elizabeth M. , Skelsey Maral
Published: March 2022

Skin cancers are often misdiagnosed or diagnosed late in skin of color (Fitzpatrick types 4-6) resulting in increased morbidity and mortality. Rare skin cancers such as Eccrine Porocarcinoma (EPC), which accounts for 0.005% to 0.01% of all epidermal skin neoplasms, are even less likely to be accurately diagnosed in skin of color.  Eccrine Porocarcinoma  is often misdiagnosed as Squamous cell carcinoma (SCC), Basal Cell Carcinoma (BCC),  melanoma, and seborrheic keratosis. The paucity of case reports of EPC in skin of color adds to the challenge of achieving accurate, timely diagnosis and treatment in this patient population. The purpose of this research is to review case reports of EPC documented in skin of color, highlighting salient clinical and histopathological characteristics of EPC, and to describe an additional case of EPC in skin of color that was initially misdiagnosed as seborrheic keratosis. Our search combined “eccrine porocarcinoma” and one of the following terms: “ethnic skin”, “skin of color”, “black”, “dark skin”, “African American”, “Indian”, “Native American”, “Asian”, “Hispanic”, “Indigenous Peoples”, “Middle Eastern” —as these tend to correspond with Fitzpatrick IV – VI types. Google scholar, PubMed, and Ovid MedLine Databases were used to search for articles. Case reports ranging from 1994 to present day were included in analysis.
Olumlu çocukluk yaşantılarının bireysel yaratıcılıkla ilişkisinde öz-saygının aracılık etkisi
Authors: TAŞ Sinem
Published: March 2022

Olumlu çocukluk yaşantıları; bireylerin öz-saygı ve bireysel yaratıcılık düzeylerinin belirleyicisi konumundadır. Ergenlik ve yetişkinlik dönemindeki olumlu veya olumsuz davranışlar çocukluk yaşantılarının mesajını taşımaktadır. Bu savı test etmek ve ilgili kavramların ilişkisini araştırmak amacıyla Burdur Mehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi lisans öğrencileri üzerinde bir araştırma yürütülmüştür. Kolayda örnekleme yöntemi ve anket tekniği kullanılarak toplamda 327 kişiden veri toplanmıştır. Bu verileri analiz etmek için AMOS 23 ve SPSS 22 paket programları kullanılmıştır. Elde edilen bulgular incelendiğinde; Olumlu çocukluk yaşantılarının hem bireysel yaratıcılığı hem de öz-saygıyı pozitif şekilde etkilediği tespit edilmiştir. Öz-saygının da bireysel yaratıcılığı olumlu yordadığı saptanmıştır. Dikkat çekici bir bulgu olarak da olumlu çocukluk yaşantılarının bireysel yaratıcılık üzerindeki etkisinde öz-saygının aracılık etmesidir. Ancak bu etkinin kısmi aracılık etkisi olduğu tespit edilmiştir. Buradan hareketle, olumlu çocukluk yaşantılarının öz-saygı düzeyini arttırdığından dolayı bireysel yaratıcılık üzerinde anlamlı bir etkisinin olduğu sonucuna ulaşılabilir. Dolayısıyla bireylerin çocukluk yaşamında deneyimledikleri olumlu duygu ve yaşantılarının yetişkinlik dönemlerinde iş hayatları için önemli sonuçlar doğurduğu söylenebilir.
Hydrogen-Bonding Capacity and Brain Penetration
Authors: Van de Waterbeemd Han , Kansy Manfred
Published: March 2022

Brain penetration has been reported to correlate with Δlog P, defined as log P (octan-1-ol/H2O) – log P (alkane/H2O). Another recent development, describing log P as the Sum of a cavity or volume contribution and H-bonding capability, the latter expressed by Asolvent values, prompted us to reinvestigate the properties accounting for brain penetration. It was found that Aalkane and the hydrophilic part of the van der Waals surface both correlate well with brain uptake. These findings offer new opportunities for the design of compounds which either should or should not be active at sites located in the brain.
Trade-off between redox potential and strength of electrochemical CO2 capture in quinones
Authors: Bui Anna T , Hartley Niamh A , Thom Alex J W , Forse Alexander C
Published: March 2022

Electrochemical carbon dioxide capture has recently emerged as a promising alternative approach to conven- tional energy-intensive carbon capture methods. The most common electrochemical capture approach is to employ redox-active molecules such as quinones. Upon electrochemical reduction, quinones become activated for the chemical capture of CO2. The main disadvantage of this method is the possibility of side-reactions with oxygen, which is present in almost all gas mixtures of interest for carbon capture. This issue can potentially be mitigated by fine-tuning redox potentials through the introduction of electron-withdrawing groups on the quinone ring. In this article, we investigate the thermodynamics of the electron transfer and chemical steps of CO2 capture in different anthraquinone derivatives with a range of substituents. By combining density functional theory calculations and cyclic voltammetry experiments, we discover a trade-off between redox potentials and the strength of CO2 capture. We show that redox potentials can readily be tuned to more positive values to impart stability to oxygen, but as a consequence, significant decreases in CO2 binding free energies are observed. This trade-off must be taken into consideration for the design of improved redox active molecules for electrochemical CO2 capture.
An Importance-Performance Analysis Of Halal Tourism Attributes And Tourist Satisfaction: Evidence From The New Zealand Muslim Community
Authors:   , Liallahu Grace
Published: March 2022

Tourist satisfaction has a vital role in success destination management. In the context of the Halal tourism market, Muslim tourists have different needs than other tourists, therefore, specific attributes such as Islamic attributes are needed. Many studies of Islamic attributes focus on the context of international tourists' satisfaction. However, no study of tourist satisfaction with Generic and Islamic tourism attributes with Importance-Performance Analysis has been undertaken in a non-Muslim country focusing on the Muslim domestic tourists.

This paper attempts to fill the research gap in the literature by exploring tourist satisfaction with tourism attributes in a non-Muslim country using Importance Performance Analysis and analyse tourism attributes by comparing it to tourists’ characteristics. The research aims are: (i) identify the importance and performance of generic and Islamic destination and accommodation attributes from the New Zealand Muslim domestic tourist perspectives; (ii) investigate Muslim domestic tourists' Satisfaction with New Zealand generic and Islamic destination and accommodation attributes using Importance-Performance Analysis; (iii) analyse differences in generic and Islamic attributes according to different tourists’ characteristics.

This study adopts the post-positivist paradigm with a quantitative research approach. The sample study of 225 Muslim domestic respondents was analysed with relevant statistical analyses. Means analysis, Importance-Performance analysis, and T-test to develop tourists’ characteristics analysis were also implemented to analyse the data.

The finding show that generic attributes were more important than Islamic attributes. Moreover, Islamic attributes need to be enhanced and develop to meet Muslim domestic tourists’ needs and satisfaction. Furthermore, the tourists’ characteristics found (11) significant differences on the attributes, with the most significant differences found in Islamic attributes at destination (5). Additionally, some suggestions affiliated with the practical recommendation and the future development of the New Zealand tourism industry are presented for the destinations and accommodation managers.
Am I Luckier Than You? Individual Differences in Precognition Performance
Authors:   , Zdrenka Marco
Published: March 2022

The results found in parapsychological research have not been
particularly persuasive, in large part due to a lack of replicability of
those studies purporting evidence in support of the existence of psi
phenomena. I propose that a more promising avenue of research into psi
focuses on the potential correlates of psi performance (i.e. factors
that correlate with above- or below-chance performance on luck-based
tasks without any known causal mechanism). Specifically, individual
differences, such as belief in ESP or extraversion, have been shown to
correlate with psi performance in forced- choice precognition
experiments (where participants predict a future chance- event by
choosing one option from a limited number of options). Thus, the goal of
this thesis was to synthesise existing literature on predictors of psi
performance, to identify the best predictors of psi performance, and to
test these predictors using the latest experimental paradigms while also
examining its external validity in the real world.
Simplifying Semiclassical Electron Transport in Highly Inhomogeneous Fields
Authors:   , Minnee Thomas
Published: March 2022

The Boltzmann transport equation describes the dynamics of electrons via
the time evolution of a 6-D scalar field. This semiclassical
description is valid in any device where the external field is
relatively constant over the decoherence length. Near equilibrium, the
electron distribution can be characterized by a local chemical potential
and the lattice temperature, leading to a simplified electron state
described by a 3-D scalar field. When external fields are large, this
approximation breaks down as the electrons are accelerated far away from
a lattice temperature thermal equilibrium. If the external field is
quasi-homogeneous, the local field or average kinetic energy can be used
to characterize the shape of the distribution function, leading to an
electron state described by one or two 3-D scalar fields. However, if
the external field is not quasi-homogeneous, there is currently no
significant simplification of the Boltzmann transport equation that is
widely accepted as being theoretically sound.
Topics in matroid union
Authors:   , Hameed Ali M.
Published: March 2022

The operation of matroid union was introduced by Nash-Williams in 1966. A
matroid is indecomposable if it cannot be written in the form M = M1 V
M2, where r(M1),r(M2) > 0. In 1971 Welsh posed the problem of
characterizing indecomposable matroids, this problem has turned out to
be extremely difficult. As a partial solution towards its progress,
Cunningham characterized binary indecomposable matroids in 1977. In this
thesis we present numerous results in topics of matroid union. Those
include a link between matroid connectivity and matroid union, such as
the implication of having a 2-separation in the matroid union, and under
what conditions is the union 3-connected. We also identify which
elements in binary and ternary matroids are non-fixed. Then we create a
link between having non-fixed elements in binary and ternary matroids
and the decomposability of such matroids, and the effect of removing
non-fixed elements from binary and ternary matroids. Moreover, we show
results concerning decomposable 3-connected ternary matroids, such as
what essential property every decomposable 3-connected ternary matroid
must have, how to compose a ternary matroid, and what a 3-connected
ternary matroid decomposes into. We also give an alternative statement
and an alternative proof of Cunningham's theorem from the perspective of
fixed and non-fixed elements.

Objective: To correlate the prevalence of COVID-19 and the rhinopathological conditions simultaneously in the population visiting the hospital of Mirpur, Azad Jammu and Kashmir. Study Design: Case-control study. Setting: District Head Quarter (DHQ) Teaching Hospital Located in Mirpur, Azad Jammu and Kashmir. Period: September 2020 to February 2021. Material & Methods: Patients visiting the DHQ teaching hospital, Mirpur, Azad Jammu and Kashmir for their COVID-19 related symptoms were included in the study. Demographic data was obtained. Prevalence of DNS and nasal polyps was recorded for further statistical analysis of the symptoms in the population. The obtained patient data was evaluated for the rhinopathological conditions that exists with the prevailing COVID-19 or may even aggravate the situation. Although nasal polyps and DNS are not among the typical symptoms of the COVID-19 but they may add to the results of PCR testing following swab testing. Conclusion: Despite being a significant relationship, there lies a chance of misleading results of swab testing as these rhinopathies obstruct the airway hindering the path. Therefore, while carrying out a confirmation test for the infection it is important to consider the chances of rhinopathies in patients beforehand.

Authors: Mohammed Farhan Qureshi  , Shoeb Qureshi
Published: March 2022

Before the end of December 2019, the epidemic was mainly localized in Wuhan, Hubei Province, China. Most of the cases in this stage were related to exposure to Huanan seafood market. "The virus is transmitted through human-to-human contact and rapidly spread across the world, and soon turned into a pandemic." Its symptoms can be divided to two main groups of majors (fever, cough, and dyspnea) and minors (anosmia, dysgeusia, headache, gastrointestinal symptoms, and skin lesions). Ever since, it has caused worldwide social and economic disruption, there are no universally recognized clinically useful antiviral drugs against COVID-19 so far (actually remdesivir showed good efficacy in many trials, but it needs to be further realized). Although there are several effective vaccines to prevent infection with SARS-CoV-2, efforts to develop medications and vaccines are continuing. Recently, a novel coronavirus, severe acute respiratory syndrome SARS-CoV-2, causing coronavirus disease 2019 (COVID-19), emerged in late 2019. During February 1-July 13, 2020, were identified 4,080 transmission pairs in Georgia, USA, by using contact tracing information from COVID-19 cases reported to the Georgia Department of Public Health. The novel coronavirus disease 2019 (COVID-19) outbreak and Italy has caused 6088 cases and 41 deaths in Republic of Korea and 3144 cases and 107 deaths in Italy by 5 March 2020. Currently, the following variants; Alpha, Beta, Gamma, Delta and Omicron were originated from United Kingdom, South Africa, Brazil/Japan, and India, respectively. The classification of SARS-CoV-2 variants is based on the mutations in the structure-based inclusions. Transmission varied not only by time and place but also by persons' sex and race. Younger adults (20–50 years of age) were involved in most transmission events.

Published: March 2022

This research aims at explaining more in-depth about Islamic hedging related to the problem of muwaâ€™adah status in Islamic hedging. The use of muwaâ€™adah as an Islamic hedging instrument which promises to carry out transactions in the future, actually still becomes a subject of debate since there are some different opinions about whether or not it is permissible to carry out the concept of muwaâ€™adah in a transaction. This research is descriptive qualitative research and uses qualitative data analysis, by conducting a direct analysis of the hedging scheme through the process of data reduction, data display, and verification. The results of this study reveal that in sharia hedging, swap and forward contracts should not be used, because swaps and forwards contain elements of usury. While the option contract contains speculation (maysir). If the forbidden aspects (haram) in â€˜forwardâ€™ and â€˜swapâ€™ instruments are analyzed, generating al-sharf al-ajil and maysir (khathar/speculation), then the alternatives are 1) forward agreement by way of a price-fixing agreement; 2) bayâ€™ al-iltizam; 3) bayâ€™ al-â€˜urbun; and 4) al-bayâ€™ bi al-shart.

Published: March 2022

Nowadays, the detection of sucralose sodium adduct under electrospray ionization in mass spectrometry analysis is a common analysis method, but its high chemical stability is not fully understood. In this work, we use quantum chemistry calculations and mass spectrometry data to understand why sodiated sucralose presents this behavior in mass spectrometry conditions. The potential energy and the position of sodium ions were evaluated using different basis sets in order to comprehend the importance of sodiation in sucralose properties. Quantum-chemical calculations show higher reliability to explain the behavior of sucralose sodium adduct under mass spectrometry conditions, especially when its molecular geometry and potential energies are evaluated.
Factor bioconcentración en Ailanthus altissima (Mill.) Swingle. Análisis preliminar
Authors: Corral Ribera Mario
Published: March 2022

El ailanto (Ailanthus altissima (Mill.) Swingle) es una de las especies exóticas invasoras más extendida a escala global. Su principal distribución está relacionada con ambientes antropizados, donde las concentraciones en suelo de elementos (metales pesados o elementos traza) pueden ser tóxicas para otros organismos vegetales. El ailanto tiene la capacidad de bioacumular estos contaminantes en sus tejidos vegetales (hojas). Se ha empleado esta especie para analizar el factor bioconcentración en diferentes ambientes antropizados (escombreras, vías de comunicación y zonas verdes) así como espacios naturalizados en la región de Madrid. También se han analizado las estrategias de Ailanthus altissima para los diferentes compuestos analizados en suelo. Los resultados indican que Ailanthus altissima absorbe del suelo una gran cantidad de elementos tóxicos de procedencia antrópica. En este sentido, la especie podría emplearse como fitorremediadora de espacios con suelos contaminados, como sucede en regiones de China.
INSTITUTIONAL STRENGTHENING OF MSMES THROUGH EASY COOPERATIVE PROTECTION
Authors: Kusumastuti Dora
Published: March 2022

A Cooperative is a business entity consisting of individuals or legal entities based on their activities based on the cooperative principle as well as a people's economic movement based on the principle of kinship. Raden Aria Wiria Atmadja was recorded in history in 1986 in Purwokerto as a pioneer or at least the inspiration for the establishment of cooperatives in Indonesia, motivated to improve the condition of civil servants, most of whom were in debt from loan sharks. Small, Micro, and Medium Enterprises (MSMEs) as the embodiment of a people's economy are able to contribute to economic growth and absorb labor. The growth of MSMEs with all their problems needs to get support through the establishment of cooperative institutions. This type of normative juridical research with secondary data sources is analyzed using deductive logic. Government Regulation Number 7 of 2021 concerning Ease, Protection, and Empowerment of Cooperatives and MSMEs is a form of support from the government for strengthening MSMEs and cooperatives in Indonesia. Support for MSMEs and cooperatives is provided by the distribution of authority to the central government and local governments in supporting the growth of cooperatives and MSMEs.

The innovation of P2P Lending that actualizes the Business-to-Business and Business-to-Consumer system has elevated economic productivity. P2P Lending offers a relatively fast and flexible money lending mechanism in which collateral is not mandatory as occurred in banking. However, the issue that arises in P2P Lending is the escalation of non-performing loan percentage that must be prevented through the implementation of effective risk mitigation by the Administrator of the Information Technology-Based Borrowing-Lending Services (Administrator). The research method used in this study is juridical-normative that utilizes the approach of laws, regulations and legal theory to analize the practice of P2P Lending within society. The results of this study indicate that Indonesia’s positive law has accommodated the risk mitigation procedures to reduce operational risk and credit risk, which are the root of the P2P Lending non-performing loan issue, namely through the implementation of CDD and EDD. OJK has a role to regulate and supervise such risk mitigation, especially to eradicate the emergence of unregistered and unlicensed Administrators by coordinating with SWI.

Published: March 2022

We present new guidelines for choosing hyperparameters for t-SNE and an evaluation comparing these guidelines to current ones. These guidelines include a proposed empirically optimum guideline derived from a t-SNE hyperparameter grid search over a large collection of data sets. We also introduce a new method to featurize data sets using graph-based metrics called scagnostics; we use these features to train a neural network that predicts optimal t-SNE hyperparameters for the respective data set. This neural network has the potential to simplify the use of t-SNE by removing guesswork about which hyperparameters will produce the best embedding. We evaluate and compare our neural network-derived and empirically optimum hyperparameters to several other t-SNE hyperparameter guidelines from the literature on 68 data sets. The hyperparameters predicted by our neural network yield embeddings with similar accuracy as the best current t-SNE guidelines. Using our empirically optimum hyperparameters is simpler than following previously published guidelines but yields more accurate embeddings, in some cases by a statistically significant margin. We find that the useful ranges for t-SNE hyperparameters are narrower and include smaller values than previously reported in the literature. Importantly, we also quantify the potential for future improvements in this area: using data from a grid search of t-SNE hyperparameters we find that an optimal selection method could improve embedding accuracy by up to two percentage points over the methods examined in this paper.

Everyday AI ethics: from the global to local through facial recognition
Authors: Daly Angela
Published: March 2022

The focus of AI ethics discussions, and flows of funding, have been concentrated at national or international levels. This contribution seeks to investigate the more ‘everyday’ practices and applications of AI ethics in local settings where individuals and communities encounterAI applications. I do this by looking at one, controversial, application of AI in the form of facial recognition technology, with a focus on how this has played out in local settings in the UK. Through the lens of legal, policy and activist activities around this technology, including protest and social movement activities, bans and moratoriums on police use of facial recognition, and litigation – I will demonstrate how a grounded, localized, everyday approach is needed in addition to higher level approaches and initiatives to understand practical implementations and contestations of AI ethics, especially emanating from protest, social movements and legal mobilisations. We must look to local settings to understand how AI ethics are negotiated, implemented and where they have actual impact. However, this ‘impact’ may not align with what researchers in AI ethics find important or are incentivized to achieve, as it may not align with government and corporate goals in AI, and instead involve prohibitions or restrictions of problematic AI uses.

Cooperation and Partner Choice Among Agta Hunter-Gatherer Children: An Evolutionary Developmental Perspective

Published: March 2022

Examining development is essential for a full understanding of behaviour, including how individuals acquire traits and how adaptive evolutionary forces shape these processes. The present study explores cooperative development among the Agta, a Filipino hunter-gatherer population. A simple resource allocation game assessing both levels of cooperation (how much children shared) and patterns of partner choice (who they shared with) was played with 179 children between the ages of 3 and 18. Children were given five resources (candies) and for each was asked whether to keep it for themselves or share with someone else, and if so, who this was. Between-camp variation in children’s cooperative behaviour was substantial, and the only strong predictor of children’s cooperation was the average level of cooperation among adults in camp; that is, children were more cooperative in camps where adults were more cooperative. Neither age, sex, relatedness or parental levels of cooperation were strongly associated with the amount children shared. Children preferentially shared with close kin (especially siblings), although older children increasingly shared with less-related individuals. Findings are discussed in terms of their implications for understanding cross-cultural patterns of children’s cooperation, and broader links with human cooperative childcare and life history evolution.
Effects of malonic acid input on fungi in dark brown soil
Authors: The Annals of Research
Published: March 2022

In this study, malonic acid was used to simulate the organic acids in the root exudates of Fraxinus mandshurica to study the impact of organic acids in root exudates on the community of fungi. Through incubation experiments and Illumina sequencing, we found that the addition of organic acids changed the relative abundance of soil fungi at the level of “phylum” and “genus”. At the fungal level, the whole process is dominated by Ascomycota fungi. The initial of priming effect may be caused by the metabolism of Trichoclaudium; the medium of priming effect may be caused by the metabolism of Penicillium; the final of the priming effect may be caused by the metabolism of Trichoderma. Upon the study, it was found that the structure of dominant bacterial communities in soil’s microflora was not changed after addition of malonic acid, but distribution pattern of relative abundance and diversity varied among microbial communities at different stages of cultivation.

Gender specificity of self- stigma, public stigma, and help-seeking sources of mental disorders in youths
Authors: Pfeiffer Simone , In-Albon Tina
Published: March 2022

Self-stigma and public stigma are major barriers to seeking help for mental health problems and they are sensitive to gender. This study investigated self-stigma and public stigma toward peers with mental disorders in a youth sample and evaluated gender differences in stigma scores. The sample consists of 1,113 youths (M = 16.96 years, SD = 1.88, 56% female) that were randomly assigned to a self-evaluation or a peer-evaluation condition using a vignette describing symptoms fulfilling DSM-5 diagnostic criteria of one of five mental disorders (depressive disorder, social anxiety disorder, ADHD, substance abuse, and bulimia). Stigma was assessed using a questionnaire assessing eight emotional reactions and attitudes toward the protagonist in the vignette. Stigma scores were significant higher in the self-evaluation condition (self-stigma) compared to the peer-evaluation condition (public stigma) in terms of a higher minimization of symptoms, higher blame for mental disorders, less pity and (self) compassion. Results indicated that prior or current experience of psychotherapy and familiarity with people seeking psychotherapy were predictors for less blame for mental disorders for the peer-evaluation but not for the self-evaluation. Gender-differences were found for public stigma, not for self-stigma. Interventions that aim to increase help-seeking intentions in youths might focus more on the reduction of self-stigma in addition to public stigma. Gender-sensitive approaches should be developed to achieve a decrease in self-stigma and public stigma especially in male youths.
On the bias in structural equation modeling when treating discrete variables as ordinal instead of continuous
Authors: Robitzsch Alexander
Published: March 2022

Structural equation modeling and confirmatory factor analysis are some of the most widely used statistical techniques in the social sciences. Frequently, variables (i.e., items) stemming from questionnaires are analyzed. Two competing approaches for estimating confirmatory factor analysis can be distinguished. First, ordinal variables could be treated as in the case of continuous variables using Pearson correlations, and maximum likelihood estimation method would be applied. Second, an ordinal factor analysis based on polychoric correlations can be fitted. In the majority of the psychometric literature, there is a preference for the ordinal factor analysis based on polychoric correlations because the continuous treatment of variables results in biased factor loadings and biased factor correlations. This article argues that it is not legitimate to speak about bias when comparing the two competing factor analytic approaches because it depends on how true model parameters are defined. This decision can be made individually by a researcher. It is shown in simulation studies and analytical derivations that treating variables ordinally using polychoric correlations instead of continuous using Pearson correlations can also lead to biased estimates of factor loadings and factor correlations. Consequently, it should only be stated that different model parameters are defined in a continuous and an ordinal treatment, and one approach should not generally be preferred over the other.
