Families Matter: A Cross-Sectional Study of Parent and Child Mental Health During COVID-19 (Preprint)
Authors: Friis Elsa , Erwin Savannah R. , Daniel Jasmine , Egger Rebecca , Egger Helen
Published: December 2021

BACKGROUND

Background: The pandemic has disrupted all aspects of children’s lives and has increased children’s exposure to adversity and traumas known to increase the risk of mental health challenges. Recent studies have reported increased rates of mental health challenges in youth during the pandemic, yet few studies have examined the impact of the pandemic on the mental health of toddlers, preschoolers, and elementary school-age children. The pandemic has also adversely impacted caregiver mental health and other indirect factors, including economic instability, known to increase children’s risk for impairing mental health challenges.

OBJECTIVE

Objective: This study aimed to characterize the social-emotional challenges of children ages 2 to 12 years old during the pandemic and identify modifiable child, caregiver, and family-related risk factors that contribute to risk and are additional targets for intervention.

METHODS

Methods: Caregivers (N = 676) of children ages 2-12 completed an online survey in early fall 2021 using standardized screening tools to assess child social-emotional challenges and caregiver anxiety and depression. We used a new 16 scale to assess the impact of the pandemic at the child, caregiver, and family levels. We used hierarchical linear regression and logistic regression to explore the relationship between children’s mental health and caregivers’ mental health. We used path analysis to explore direct and indirect effects of the impact of pandemic stress on child emotional and peer challenges, mediated by caregiver anxiety and depression.

RESULTS

Results: Eighty-seven percent of the children were ages 2-8 years old (n=588) with 13% (n=88) between 9-12 years old. Caregivers endorsed significant child emotional and peer challenges with 80% (n = 536) of children at risk for clinically-significant emotional challenges and 57% (n = 388) at risk for clinically-significant peer social challenges. Emotional challenges increased with age (r = .20, P <.001). 50% (n=330) of caregivers screened positive for generalized anxiety and 24% (n=160) screened positive for depression. Cumulative COVID-19 impact was directly associated with increased child emotional challenges (r=.29, P<.001), peer challenges (r=.29, P<.001), caregiver anxiety (r = .32, P<.001), and caregiver depression (r = .42, P<.001). Caregiver anxiety accounted for 31% of the total effect of COVID-19 impact on child emotional challenges and 18% of the total effect on peer challenges.

CONCLUSIONS

Conclusions: The results of our study show that the COVID-19 pandemic is having direct and indirect adverse impacts on the social-emotional health of children ages 2 to 12 years old with impacts on very young children similar to impacts for older children. Only with an integrated, family-focused approach that includes young children will we be able to mitigate the current pediatric mental health crisis.

Shifting the Blame: Storm and Wildfire Dramatic Images in American News Media
Authors: Munandar Aris , Basuki Amin
Published: December 2021

Some media frames might be likely to seek to evoke a certain sentiment, and that natural disaster coverage by the media focuses on the current impact of disasters. In their coverage, American news media use polar sentiment words to create bleeding images of natural disasters, potentially counter-productive to the wisdom of dealing with the natural disaster. Identifying the sentiment words that lead to a misperception of natural disasters can help journalists adopt the wisdom that natural disasters are not a human enemy. The corpus-assisted discourse studies (CADS) reported in this article investigates the American media's issues for dramatic reporting and the polar sentiment words utilized in the framing. The corpus is built from 100 news articles reporting wildfires and storms by ten major online American news media published from January 1, 2018, through December 31, 2020. It uses AntConc to generate word-list and word-link from which it identifies the dominant issues. Subsequently, it compares the AntConc word-list with A List of Sentiment Words to reveal the tones and dramatic imaging. The findings show that the dominant issues in storm reporting are description, impact, and prediction, while wildfire reporting are cause, impact, action, and prediction. The negative polar words produce dramatic images of storm as a violent beast and wildfire as a vengeful invader. Such description is provocative to blaming natural disasters as a cause of human suffering rather than improving our behaviors to reduce the suffering. Thus, it is counter-productive to acquiring wisdom for dealing with natural disasters.

Authors: Bates Cynthia T. , Shaw Julia Penn , Thomas Stephanie L. , Lawless John J.
Published: December 2021

This paper presents the Process Improvement Request System initiated at SUNY Empire State College as a case study for institutional change management. Through this system, employees can submit suggestions for improving any kind of institutional processes at the college using an Information Technology “ticketing” system like the one used for technical issues. These communications are addressed, tracked, and stored by the Process Improvement Committee which includes representatives from all areas of the college. The Process Improvement Request System addresses many critical goals including 1) the storage of process issues, concerns, and suggestions; 2) a mechanism for addressing these; 3) open access to all employees (and to students through employee representatives) to submit ideas; 4) the ability to make suggestions about all levels of process issues, from college wide to personnel specific; 5) anonymity for making a request when desired; and 6) a feedback loop about the effectiveness of new processes. In this paper, the essential aspects of this project are discussed and analyzed. The paper also enables readers to ascertain the viability of such a project at their campuses and invites them to reach out to the authors if they have questions about doing so.
Analysis of Operating Modes of Oil-Immersed Power Transformers with a Voltage of 10 (6) / 0.4 kV
Authors: Fokeev A.E. , Tumakov I.N.
Published: December 2021

The rate of thermal aging of the power transformers windings insulation depends on the effects of the electric field, mechanical stresses, temperature and processes that cause changes in these factors. A calculation algorithm is considered that allows determining the temperature of the most heated point of the windings of an oil power transformer at known values of the load current and ambient temperature. Calculation of the most heated winding point temperature and the rate of thermal aging of insulation for an oil power transformer at different ambient temperatures during the year, different values and different spectral composition of the electric load current showed that in some cases it is possible to violate the permissible operating conditions of power transformers. According to the calculation results, the dependences of the thermal aging rate of insulation on the ambient temperature are constructed, with different load parameters and different load coefficients of power transformers. For the considered modes, in the warm season, the value of the thermal aging rate of insulation significantly exceeds the nominal value. Based on mathematical models of oil power transformers with natural and forced oil circulation, expressions are obtained for determining the coefficient of reduction of the oil power transformers permissible load when the ambient temperature exceeds the normal value of 20 °C. On the basis of these expressions, for practical use, the dependences of the coefficient of reduction of the permissible load on the ambient temperature are constructed. The influence of ambient temperature must be taken into account when choosing the power of oil power transformers, for which it is assumed to operate in full redundancy mode or high load factor values (³ 0.8) in normal mode. To ensure the normative service life of the insulation of the windings, it is necessary to determine the design power of oil power transformers using the coefficient of reduction of the permissible load under the influence of higher harmonics of the current and the coefficient of reduction of the permissible load under the influence of ambient temperature.

School Leadership and the Experience of Education Under Oppression
Authors: Deitle Kevin , Lee Daniel
Published: December 2021

Background: This qualitative study examined apartheid-era South Africa, from 1948 to 1994, which established social and administrative policies that deliberately curtailed the education of Indigenous and other South Africans as a means of oppressing non-European ethnic groups.
Analysis: In lieu of face-to-face interviews, the experience of education under apartheid is examined through stories and interviews submitted to the Apartheid Archives Project, curated by the University of the Witwatersrand, in Johannesburg, South Africa. The central question asks how the personal experiences of an oppressive school system, as interpreted through the framework of Freirean education, informs school leaders.
Conclusion: Oppression infiltrates school systems, impinges on the educational process, and robs students of learning opportunities. In recognizing this, educators engage their responsibility as school leaders, and embrace the pivotal role education plays in social reconstruction, liberation, and humanization.

La investigación tuvo por objetivo determinar la eficacia jurídica de las normas que regulan la comercialización de madera en el departamento de Caldas. Desde lo meto-dológico, el estudio se desarrolló mediante un enfoque mixto, con método inductivo y alcance hermenéutico descriptivo; las técnicas de recolección de información fueron la encuesta Delphi y el nivel de acuerdo entre los expertos temáticos (kappa de Cohen). Como resultado de la investigación, se presenta el recuento normativo respecto a la comercialización de madera, desde las clases de eficacia de la norma, para el departamento de Caldas. Se evidenció que las mayores infracciones se presentan en el aprovechamiento, identificando a su vez que, para consolidar el análisis de la comercialización desde la perspectiva normativa, procedimental y de eficacia, todo se resume en estrategias de educación ambiental, que permitan a los actores de la cadena conocer y aplicar la norma, a fin de lograr mejores resultados en la legalidad de la madera y su comercio. Es necesaria la actualización normativa, que se ajuste a juicios técnicos asociados con la protección y diagnósticos ambientales particulares para las zonas de Colombia, teniendo en cuenta que, acorde a lo identificado en la investigación, algunos criterios se fundamentan en conocimientos propios del profesional que atiende el caso y aplica los lineamientos normativos, y no a parámetros estandarizados frente a las particularidades ambientales y de especificidad en cada contexto.

Published: December 2021

Urban tourism is identified as one of the main destinations of the XXI century. Its intensification is associated with overcoming the critical situation in the industry, which will require expanding the variety of tourist products. The potential opportunity for this matter will include active involvement of botanical resources in them, which will enable increasing interest for the existing projects as well as selecting the most promising ones. It is noted that vegetation cover is an integral component of all urbanized territories not used in the full volume in the tourist product of cities despite the resources’ high potential. Cartographic method is presented as the universal, informative, visual and operational-predictive one. The purpose of the study was to create a cartographic interpretation of the botanical resources potential usage for urban tourism development using the example of Khabarovsk. For the first time, a map “Objects with high potential of botanical resources for tourism development in Khabarovsk” (scale 1
Geodetic foundations of cartography in Europe in 19th century
Authors: Lapaine М.
Published: December 2021

Geodetic surveying comprises the determination of locations on and the dimensions of the earth’s surface at a various scales. In the 19th century, its technologies are those of direct measurement of the earth’s surface combined with astronomical observations. Its social context encompasses all those individuals and institutions involved in the creation, preservation, use, and arrangement of knowledge of the earth. In the introductory part of the paper the author mentions several important events in the history of the 19th century geodesy. Geodetic work on determining the size of the Earth by measuring the lengths of the meridian arcs continues in this century. An international surveying organization was established and the international meter convention adopted. Basing on a detailed research of geodetic surveying in Central, Eastern and Southeastern Europe in the 19th century, a part of these surveys is presented that relates to Switzerland, Austro-Hungarian Monarchy, Austria, Hungary, Slovenia and Croatia. Common to all these geodetic surveys is that they were necessary for the development of cartography and were carried out by military institutions. The developed geodetic networks are characterized by the use of different ellipsoids, different prime meridians, different coordinate systems and their origin. In the area under consideration in the 19th century, there were five different ellipsoids in use suggested by Bessel, Bonenberger, Schmidt, Valbeck and Zach. Prime meridians were
Gravity acceleration changes in Russian stations of comparing absolute gravimeters
Authors: Yushkin V.D. , Zotov L.V. , Basmanov A.V. , Sermyagin R.A.
Published: December 2021

The article deals with the study of changes in the values of gravitational accelerations at the Russian comparison’s sites of the absolute gravimeters “Pulkovo”, “Svetloye” and “Zvenigorod” for the years of 2007–2013. A significant increase of the values instead of the expected decrease was obtained. The authors make an attempt to reveal the reasons for that basing on the calculation of the change in the gravitational field using the Bouguer and Faye corrections. The estimates do not fully explain the phenomenon, according neither to gravimeters nor to satellite data. At the sites of “Pulkovo” and “Svetloye”, the measured changes in the values differ from the calculated ones by +5,7 and 6,6 μGal, which significantly exceeds the errors of the absolute gravimeters. The change of the gravity varies from satellites GRACE data by 9,4 μGal at the “Zvenigorod” site. This may be due to local hydrological reasons. Determining the causes of gravity changes at the absolute stations of gravity network is an urgent task.
Reseña del libro Sapiens. De animales a dioses. Una breve historia de la humanidad de Yuval Noah Harari (2014)
Authors: Arcila Rojas Claudia , Arcila Rojas María Camila
Published: December 2021

Aunque tal vez sea muy ambicioso iniciar este escrito con la intención de responder por qué Yuval Noah Harari habría escrito el libro Sapiens. De animales a dioses. Una breve historia de la humanidad, nos hemos dispuesto a dialogar con nuestras sospechas, intuiciones y riesgos en una especie de intimidad compartida con el texto frente a los mensajes que nos atravesaron y nos sensibilizaron a pensarnos como sujetos en las dinámicas de este mundo moderno, el cual, como lo propone el autor, está dirigido por la ambición en las lógicas del dinero. Con esta premisa decidimos, desde la misión de pensar en la razón de la escritura de este texto, iniciar con la hipótesis de que la intención de Harari es alertarnos frente al tiempo de la globalización y su dominio a través de los imperios. Para el caso de nuestro continente latinoamericano, este dominio no corresponde solamente a los tentáculos de presión que genera el imperio norteamericano a nivel económico.

Traducción del francés al español de Luis Alfonso Paláu-Castaño

«Una de las cuestiones fundamentales a las que toda interrogación filosófica termina por conducir es probablemente la del sentido. Inmediatamente, el sentido no es el objeto de una averiguación; está dado primitivamente como una evidencia inmediata. Una vez planteada la pregunta, en un segundo tiempo el filósofo se dedica a cuestionar esa evidencia como si ella velase un irritante misterio. Es solamente entonces cuando la averiguación comienza. Esta búsqueda pasa por un examen minucioso de todos los órdenes, de todas las estructuras, tanto las del universo como las que resultan de nuestras actividades más diversas. Hemos esbozado un examen tal en dos obras precedentes (Chazal, 2011, 2000).»
Features of the Oceanological Values Fields in the Sivash Bay (The Sea of Azov)
Authors: Lomakin P. D. ,   Marine Hydrophysical Institute, Russian Academy of Sciences, Sevastopol, Russian Federation
Published: December 2021

Purpose. The study is aimed at revealing the structural regularities and variability of the fields of temperature, salinity, the colored dissolved organic matter and total suspended matter concentrations, and also the factors that form them in the Sivash Bay. Besides, the results obtained are to be compared with the already known features of the fields of the values under investigation which are typical of the Azov-Black Sea coastal zone; and the response in the considered fields to the North Crimean Canal damming is to be assessed. Methods and Results. Based on the data of 8 expeditions carried out by Marine Hydrophysical Institute in 2013–2016, the structural regularities and variability of the fields of temperature, salinity, the colored dissolved organic matter and total suspended matter concentrations, and the factors that form the fields of these values in the Sivash Bay were revealed. The quantitative indicators of changes in the fields of the considered values, which arose after the North Crimean Canal was dammed, are represented. Conclusions. In the region under study, a number of constantly acting factors that determine formation of special, not typical of the coastal area, features of the oceanological values fields are identified, namely: the influence of the Azov Sea and the North Crimean Canal waters, the rivers inflowing to the water area of the Sivash western coast, the isolated lakes, the swampy shallow bays and the isolated, relatively deep, parts of the coastline. Three years after the North Crimean Canal was dammed, in the northwestern Sivash salinity increased by 20 PSU. The opinion that Sivash is not a typical sea bay, but a connected with the Azov Sea reservoir with the signs of a salt swamp is confirmed

Published: December 2021

A membrane adsorber with hierarchically porous HKUST-1 (HP-HKUST-1)
immobilized in membrane pores has been fabricated by flowing synthesis.
The XRD characteristics indicated that the structure integrity of the
HP-HKUST-1 immobilized in the membrane pores can be kept after template
agent removed. Other characteristics presented by XPS, FTIR, SEM, TEM
and BET proved the effective immobilization of HP-HKUST-1 in membrane
pores. Compared with hydrothermal HKUST-1 powder, the adsorption
capacity for Congo red and Methylene blue adsorption can be increased
several times by hydrothermal HP-HKUST-1 powder, owing to the mesopores
with rich active sites for adsorption. When the solution was flowed
through the membrane adsorber, the adsorption rate for these adsorbates
increased significantly, owing to the enhanced mass transfer in the
confined space of the membrane pores with micro or nano scale. After
going through seven adsorption-desorption experiments, the membrane
adsorber with HP-HKUST-1 immobilized in membrane pores shows a
remarkable repeatability.

Published: December 2021

Infectious complications have been shown to increase the morbidity of
venous-venous extracorporeal membrane oxygenation (VV-ECMO) population,
including the use of right ventricular assist devices. We aimed to
evaluate our VV-ECMO population for ECMO related bloodstream infections
(E-BSI) and characteristics that affect risk and overall outcomes. We
report a low infection rate of 2.7%. We postulate our low BSI rate may
be due to our use of perioperative antimicrobials as well as a majority
of our cannulations occurring in the operating room. Further
investigation into trends, risks, and outcomes related to E-BSI is
needed.
An individually-controlled multi-tined expandable electrode using active-cannula-based shape morphing for on-demand conformal radiofrequency ablation lesions
Authors: Chai Zhiping , Lyu Liangxiong , Pu Menghao , Liang Huageng , Ding Han , Wu Zhigang
Published: December 2021

Being minimally invasive and highly effective, radiofrequency ablation
(RFA) is widely used for small size malignant tumors treatment. However,
in clinical practice, a large number of tumors are found in irregular
shape, while the current RFA devices are hard to control their
morphologic appearance of RFA lesions on demand, which usually ends up
excessively ablating the tissues and often brings excessively
irreversible damage to the organs’ functions. Here, we introduce active
cannulas for each of individually-controlled sub-electrodes to achieve
an on-demand shape morphing and thus conformal RFA lesion. The shape as
well as the length of inserted sub-electrode can be precisely controlled
by tuning the expanded length of the active stylet and relative position
of the active cannula. Furthermore, owing to independent movement and
energy control of each sub-electrodes, our electrode is shown to be not
only efficient enough to accomplish accurate trajectory to target tissue
in a single insertion, but also adaptive enough to ablate target tissues
with diverse morphologic appearances and locations. Potentially, our RFA
electrode is a better choice in the future clinical practice for
minimally invasive treatments of malignant tumors of which preferred
treatment is conformal ablation.

Procjena utjecaja pandemije bolesti COVID-19 na poslovanje elektroničkih medija u Republici Hrvatskoj
Authors: Popovac Josip , Gavran Vanja
Published: December 2021

Pandemija bolesti COVID-19 utjecala je na sve segmente društva pa tako i na medije. Narušavanje ukupne ekonomije utjecalo je na ekonomsko poslovanje medija, ali i na kvalitetu programskih sadržaja jer su društvene aktivnosti reducirane uslijed niza mjera kojima se sprječava širenje virusa. Mediji gotovo da nisu imali o čemu izvještavati ako to nisu bile teme vezane za pandemiju i, dakako, političke teme. Cilj je ovog rada procijeniti koliko je pandemija utjecala na ukupno poslovanje elektroničkih medija u Republici Hrvatskoj. Prije svega, u teorijskom je dijelu rada bilo riječi o samoj medijskoj regulaciji općenito te u Hrvatskoj, kao i aktivnostima koje su poduzete kako bi negativan utjecaj pandemije na hrvatske elektroničke medije bio što manji. U drugom dijelu rada predstavljeni su rezultati istraživanja koje su proveli autori ovog rada u okviru Agencije za elektroničke medije upravo kako bi se dobila jasnija slika o utjecaju pandemije. Kvantitativno istraživanje, online anketa, provedeno je u siječnju 2021. godine među pružateljima različitih elektroničkih medija koji su upisani u Upisnik pružatelja medijskih usluga, elektroničkih publikacija i neprofitnih proizvođača audiovizualnog i radijskog programa, a koji vodi Agencija za elektroničke medije. Istraživanjem su prikupljeni podaci o financijskom utjecaju pandemije, ali i o njezinu utjecaju na kvalitetu programa pružatelja medijskih usluga. Isto tako, autori su istraživanjem dobili informacije o broju zaposlenika u ispitanim medijima koji su bili zaraženi virusom COVID-19 te broju preminulih, kao i podatke tj. ocjenu medija o načinu kako su sami mediji informirali javnost o pandemiji i kako su mjerodavne institucije informirale medije o pandemiji.

Drazin inverse. Let R be a ring, and let a, b, c, d ? R satisfying (ac)2 =
(db)(ac), (db)2 = (ac)(db), b(ac)a = b(db)a, c(ac)d = c(db)d. Then ac ? Rd
if and only if bd ? Rd. In this case, (bd)d = b((ac)d)2d: We also present
generalized Cline?s formulas for Drazin and group inverses. Some weaker
conditions in a Banach algebra are also investigated. These extend the main
results of Cline?s formula on g-Drazin inverse of Liao, Chen and Cui (Bull.
Malays. Math. Soc., 37(2014), 37-42), Lian and Zeng (Turk. J. Math.,
40(2016), 161-165) and Miller and Zguitti (Rend. Circ. Mat. Palermo, II.
Ser., 67(2018), 105-114). As an application, new common spectral property of
bounded linear operators over Banach spaces is obtained.

Esters of angelic, senecioic and tiglic acids with various saturated/
unsaturated/aromatic alcohols contribute to the aroma of many essential
oils. However, mass spectrometry with electron-impact ionization sometimes
fails to distinguish these regio-/geometric isomers and this was the case
with the minor constituent of Helichrysum italicum (immortelle) essential
oil that was tentatively identified as the ester of 2- phenyl-1-ethanol with
one of the mentioned acids. Our efforts to identify this phenethyl ester
were also hampered by the inconsistency or by the lack of appropriate RI
data in the literature. Therefore, we prepared and fully spectrally
characterized (1D- and 2DNMR, IR, MS) synthetic samples of all three
isomeric esters. Subsequent GC analyses of immortelle oil samples with
spiked synthetic phenethyl esters unambiguously confirmed that the compound
in question was phenethyl angelate. This rare plant secondary metabolite has
been previously reported only twice as a constituent of samples of natural
origin. However, the outcomes of our study strongly imply that this molecule
was misidentified in these earlier studies with the corresponding
senecioate/tiglate. Thus, the existing libraries of RI/MS data for tiglates
and angelates have to be upgraded with appropriate data for senecioates to
avoid these kinds of errors in the future.
Assignment of 1H and 13C NMR spectral data of diastereomeric acetals directly from their mixture by spectral simulation
Authors: Nesic Milan , Radulovic Niko
Published: December 2021

Herein, an NMR spectral analysis was performed of a mixture of diastereomeric
acetals synthesized from 2-fluorobenzaldehyde and a racemic mixture of
4-methylpentan-2-ol. The simulated 1H- and 13C-NMR spectra of individual
diastereomers, as well as their superimposed and summed spectra, were
compared with the obtained experimental spectra. Spin simulation of proton
signals was particularly useful for the assignment of the aromatic part of
the molecules and of the diastereotopic protons of the methylene groups. The
isomer NMR spectral data - chemical shifts, coupling constants, HMBC and
NOESY interactions were systematized in appropriate tables and schemes.

After potato, tomato (Solanum lycopersicum) is the world?s second-largest
vegetable crop. More than 80% of tomato consumption comes from processed
products such as ketchup, tomato juice, pickled tomatoes, sauces, paste,
pur?e. Samples of mild ketchup from two different manufacturers (A and B)
were selected for the analysis of the content of natural food colors E160a
and E160d. Using a UV-Vis spectrophotometric method and Lambert-Beer law, a
system of two linear equations with two unknowns was set up, which was used
to determine the concentrations of colors E160a and E160d. The antioxidant
capacity of the two selected samples was determined using the DPPH assay.
The obtained results indicated that the content of colors E160a and E160d
was higher in the sample of ketchup B. Also, the DPPH assay showed that the
sample of ketchup B had a higher antioxidant capacity.
Greek books of the Dimitrije Davidovic’s printing house in Vienna
Authors: Vojnovic Zarko
Published: December 2021

Dimitrije Davidovic's printing house did not fulfill the expectations of
Serbs, nor his personal ones, during its three years of work in Vienna.
Because he did not get the general printing right, he got into big financial
trouble. Using his acquaintance with the rich Greek-Aromanian family Darvar,
he tried to overcome these problems by printing books in Greek. Taking into
account the fact that this is still unknown in Serbian science, we present
the available data on it, considering it important for the Serbian national
bibliography, and in this way specific international cultural relations are
additionally presented. At the end of the paper, a list of all Greek books
that Davidovic printed is given.
Jovan Ducic and the Serbian citizenship
Authors: Stanic Mile
Published: December 2021

This paper is based on data from the archives of the official institutions of
the Kingdom of Serbia, namely the Serbian Ministry of Interior?s Registry
for the years 1907 and 1908 and the Belgrade City Administration?s Registry
of Persons Granted the Serbian Citizenship. Due to a lack of documents and
archival material destroyed in World War I, these formal registries were
used as proof of completed administrative procedure for granting the
citizenship of the Kingdom of Serbia to Jovan Ducic at his request. The
paper also presents a facsimile of the Terazije Square hotels guest list on
3rd January 1907, featuring the name of Jovan Ducic, who had only just
arrived in Serbia. In addition, the paper features a drawing of the Serbian
Ministry of Interior building, torn down just before World War I, in which
Ducic started his diplomatic career.

Using Storytelling to Apply Lessons from PCAOB Enforcements
Authors: Herron Terri L. , McNellis Casey J.
Published: December 2021

The real-life failures of others provide opportunities to learn. Audit failures and rule infractions stemming from Public Company Accounting Oversight Board (PCAOB) inspections represent the few instances for which detailed information about financial statement audits is made publicly available. The PCAOB enforcement reports contain key information and offer greater transparency in regard to the audits of SEC registrants. This project uses these reports to teach real-life lessons in the context of the complex regulatory environment in which registered audit firms operate. Students examine the information from these enforcements, and craft and present stories of the related audit failures. This approach has a proven impact on learning, and students who completed the project reported enhanced knowledge of the regulatory process and audit standards. The student presentations can be used in a professional environment for CPAs to earn CPE. We provide advice to faculty who wish to pursue a similar option.

Chitinase-3-like Protein 1 (YKL-40): A New Biomarker of Inflammation in Pyoderma Gangrenosum
Authors: Jankowska-Konsur Alina , Łyko Magdalena , Rubas Klaudia , Nowicka-Suszko Danuta , Maj Joanna , Szepietowski Jacek C.
Published: December 2021

Pyoderma gangrenosum (PG) is a rare, neutrophilic dermatosis with unclear aetiopathology, considered as an autoinflammatory disease, associated with other immune-mediated disorders. Chitinase-3-like protein 1 (YKL-40) is an inflammatory biomarker secreted by a wide variety of cells, including neutrophils. To evaluate YKL-40 serum level in relation to clinicopathological data, 48 patients with PG and 40 healthy controls were enrolled in the study. Skin lesions were measured to calculate the affected area. Inflammatory parameters (C-reactive protein, white blood cell count with neutrophils) were determined from blood samples. YKL-40 and IL-6 levels were measured in serum by enzyme-linked immunosorbent assay. YKL-40 serum level was significantly higher in patients with PG than in controls (58.4 vs 36.4 ng/ml, respectively; p < 0.00001). The positive correlation between YKL-40 level and IL-6 level was observed (r=0.48, p = 0.0006) along with a trend towards significance of relationship between YKL-40 level and C-reactive protein (r=0.28, p = 0.052). YKL-40 can be considered a valuable biomarker of inflammation in PG.
Effect of wire feeding speed on dissimilar laser welding of NiTi shape memory alloy and 2A12 aluminum alloy
Authors: Cheng Qi , Guo Ning , Zhang Di , Fu Yunlong , Zhang Xin , Chen Hao , He Jinlong
Published: December 2021

Laser welding of NiTi shape memory alloy (SMA) and 2A12 aluminum alloy was realized by using a TC4 wire. Due to the poor metallurgical compatibility of Ti and Al elements, the surface appearance of welded joints was uneven and fluctuated. No obvious cracks were found on the surface. When the wire feeding speed increased to 280 cm/min, the pores at the interface disappeared. There were mainly a fusion zone (FZ), the NiTi SMA/FZ interface, and the 2A12 aluminum alloy/FZ interface in the welded joints. Some dendritic microstructures grew vertically toward the FZ at the NiTi SMA/FZ interface. The distance grown of the microstructure at the interface reduced while the wire feeding speed increased. Due to the increase of wire feeding speed and the decrease of the heat input per unit volume, the ability of the atoms to diffuse and migrate reduced and the trend grown of the microstructure was inhibited. For the FZ, there were α-Ti + β-Ti + Ti2Ni phases. The difficulty of decomposition for the β-Ti phase increased because the molten pool contained a large amount of the Ni elements and a small amount of Fe and V elements. After the molten pool cooled, there would be the β-Ti phase in the FZ. With the increase of wire feeding speed, the intermetallic compounds changed from Ni–Ti to Al–Ti. Besides, the fracture load of welded joints first increased and then decreased. When the wire feeding speed was 280 cm/min, the maximum fracture load of the welded joint was 176 N/mm and the fracture mode of the joint was an intergranular brittle fracture.
„Wieczny jak piramidy pomnik nieśmiertelnej pamięci”. Uwagi o epitafijnej funkcji portretu trumiennego w okresie nowożytnym
Authors: Jankowski Aleksander
Published: December 2021

Artykuł poświęcono dotychczas nieopracowanej w literaturze przedmiotu kwestii funkcji, jakie portret trumienny spełniał po pochówku. Wizerunek zmarłego zawieszany w przestrzeni sakralnej utrwalał pamięć o nim oraz podkreślał jego „obecność” w czasie liturgii. Podstawą analiz są przede wszystkim inskrypcje identyfikujące zmarłego, towarzyszące wizerunkowi, przeważnie umieszczane na osobnych blachach mocowanych z portretem do trumny. Teksty te często mają formę panegiryku, a zawierają zwroty adresowane głównie do uczestników praktyk religijnych już po pochówku. Inskrypcje odzwierciedlają odmienne wizje zaświatów u katolików i protestantów.
