Impacto da internacionalização no risco financeiro das empresas listadas na B3: análise dos efeitos moderadores do desempenho ESG e dos períodos de crise
Authors: Rosa Arthur Antonio Silva , Ribeiro Kárem Cristina de Sousa
Published: September 2023

Objetivo: Analisar a relação entre a expansão internacional e o risco financeiro das empresas brasileiras não financeiras de capital aberto, considerando os efeitos moderadores do desempenho ESG e dos períodos de crise.
Método: Utilizou-se como amostra empresas brasileiras não financeiras listadas na B3, no período de 2010 a 2020, e realizou-se regressões lineares múltiplas com efeitos fixos ou aleatórios e com dados em painel, de forma que os resultados foram controlados por variáveis corporativas e macroeconômicas.
Resultados: Empresas com maior grau de expansão internacional tendem a apresentar um maior risco total, no entanto, apresentam um menor risco sistemático. Também se constatou que o desempenho ESG possui um efeito moderador negativo na relação entre expansão internacional e risco financeiro. Ademais, em períodos de crise, empresas mais internacionalizadas e com maior desempenho ESG, tendem a diminuir o seu risco total. Dessa forma, embora a internacionalização possa aumentar o risco financeiro, o desempenho ESG pode ser utilizado como uma estratégia para atenuá-lo, sobretudo em períodos de crise.
Contribuições: O estudo contribui para a teoria por indicar que a expansão internacional se relaciona de forma distinta com o risco total e com o risco sistemático, no contexto das empresas brasileiras. Além disso, a pesquisa indica que o desempenho ESG e os períodos de crise exercem um efeito moderador na relação entre internacionalização e risco financeiro. Também possui implicações práticas, pois pode auxiliar os gestores cujas empresas estão em processo de internacionalização a utilizarem o desempenho ESG como estratégia para atenuar o risco financeiro dessas companhias, sobretudo em períodos de crise.

Published: August 2023

Objetivo: O objetivo do presente estudo foi determinar a prevalência de periodontite apical e sua relação com a presença de tratamento endodôntico e diferentes tipos de restaurações em uma população turca adulta selecionada. Métodos: O estudo foi composto por 1.002 pacientes e 5.764 dentes. O estado de saúde periapical foi avaliado pelo índice periapical sugerido por Ørstavik et al. Para a análise estatística, foram utilizados os testes qui-quadrado e Exato de Fisher. Resultados: As doenças periapicais (2%) foram significativamente menores na faixa etária entre 50 e 59 anos (p = 0,000; p < 0,05). A presença de periodontite apical foi estatisticamente maior na mandíbula (6,1%) (p = 0,000; p < 0,05). A maior incidência de doença periapical foi observada nos dentes anteriores (7,3%) (p = 0,000; p < 0,05). Dentes submetidos a tratamento endodôntico apresentaram maior taxa de periodontite apical (10,8%). Com relação aos tipos de restauração, tanto os dentes com pino e coroa (13%) quanto apenas coroa (9,4%) apresentaram a maior taxa de doença periapical (p < 0,05). Conclusões: A presença de tratamento do canal radicular é o fator mais importante para o aumento do risco de periodontite apical, entre os outros parâmetros examinados. Entre os tipos de restaurações examinados, as restaurações tipo pino e coroa tiveram o maior risco de doença periapical, seguidas pelas do tipo coroa.

Published: September 2023

Pop-up stores are a way to promote exposure in ambient media, which stimulates the interest of potential customers. The study examines how in-store atmosphere, surprise factors, brand experience, brand attitude, word-of-mouth (WOM), and purchase intentions are structured and influence each other. The study chooses a pop-up store that is an online women's shoe brand to conduct the research. A total of 480 usable samples were used in the study. The study has adopted structural equation modeling (SEM) with the help of AMOS software to bring the outcomes of the research. The study finds that the store atmosphere affects the surprise factors, brand experience, and brand attitude. Whereas, surprise factors positively affect the brand experience and brand attitude. The brand experience impacts brand attitude and WOM. However, the brand experience is affecting the purchase intention in the study. The study also finds that the brand attitude affects the WOM and purchase intention. Further, WOM is affects the purchase intention in the study. So far, there has been no research conducted on the attitudes and behaviors of consumers affected by online-to-offline pop-up shops. Therefore, as part of the present study, consumer sentiment generated by pop-up stores is explored concerning consumers' attitudes and behaviors towards the brand, thereby providing the industry with a reference for creating pop-up stores. The gap in research regarding setting up online to offline pop-up stores that are currently lacking is filled by researchers, academicians, and the sector.

Pengembangan Lahan Skala Besar dan Transformasi Sosial-Ekonomi Masyarakat di Sekitarnya: Bukti dari Pengembangan Summarecon Bandung dan Rencana Pengembangan TOD Tegalluar
Authors: Kaffah Mukhlis Silmi , Winarso Haryo
Published: September 2023

Beberapa tahun terakhir, pengembangan lahan skala besar kian intensif dilaksanakan, terkhusus di wilayah perbatasan kota dengan ketersediaan lahan yang memadai sehingga relatif terbebas dari konflik. Pengembangan lahan skala besar menghasilkan pengaruh yang besar serta kurun waktu yang lama untuk masyarakat. Hal tersebut dapat menciptakan transformasi sosial-ekonomi seperti perpindahan penduduk, pergantian jenis pekerjaan, serta kenaikan penghasilan keluarga. Di samping itu, akan terdapat pergeseran dari kegiatan utama pedesaan (pertanian) menjadi kegiatan utama perkotaan (perdagangan dan jasa). Riset ini hendak memaparkan transformasi sosial-ekonomi masyarakat di sekitar pengembangan lahan skala besar Summarecon Bandung dan TOD Tegalluar. Riset ini fokus pada sejumlah aspek transformasi, yaitu perpindahan penduduk, jenis pekerjaan, serta penghasilan dan pengeluaran keluarga. Lingkup wilayah studi mencakup lima desa/kelurahan, yaitu Kelurahan Cisaranten Kidul, Kelurahan Rancabolang, Kelurahan Cimincrang, Kelurahan Rancanumpang, dan Desa Tegalluar. Riset ini menggunakan metode campuran dengan analisis deskriptif dan statistik terhadap hasil kuesioner pada rumah tangga di sekitar pembangunan Summarecon Bandung dan TOD Tegalluar. Riset memperlihatkan bahwa telah terjadi transformasi sosial-ekonomi pada masyarakat sekitar pengembangan lahan skala besar, walaupun tidak secara signifikan. Transformasi tersebut terlihat dari adanya perpindahan penduduk ke wilayah studi dengan persentase yang meningkat, semakin beralihnya jenis pekerjaan dari sektor primer ke sektor sekunder dan tersier, serta semakin baiknya perekonomian masyarakat.
Rescue of the critically endangered long-stalked pondweed (Potamogeton praelongus) in the Czech Republic
Authors: Prausová Roamana , Janova Jana , Adamec Lubomir
Published: August 2023

Potamogeton praelongus occurs in the Czech Republic at only one natural site. As part of a rescue programme, micropopulations were introduced into new locations. The aim of the paper is to describe the realised measures: monitoring micropopulations and habitat factors at P. praelongus sites, investigation of seed germination, and preparation of a sterile in-vitro culture for plant propagation and conservation purposes. Between 2008–2010, both micropopulations in the Orlice floodplain increased their size by three times annually. In 2010, 1461 shoots occurred at the natural site and 199 at the artificial one. In 2010, stand areas varied between 12–50 m2. The most effective treatment to break seed dormancy involved 2-h surface sterilisation in 5 % or 2.5 % NaClO solution proceeded by a period of desiccation, temperature variation, hypoxic conditions, and mechanical abrasion of the seed coat.Using similar methods of NaClO sterilisation, an in-vitro culture of P. praelongus was prepared and 30 clones with an expected genetic variability are available.

Authors: Fuxjäger Christian , Laass Jens , Molinari-Jobin Anja
Published: August 2023

To assess the status of Eurasian lynx (Lynx lynx) in the Austrian Alps we evaluated signs of lynx presence collected from 2005 to 2009. The spatial distribution and the number of records collected (228 versus 225) remained stable compared to the 5-year period 2000–2004. The distribution of the signs of presence showed three clusters: (1) the clearest in Upper Austria (Kalkalpen National Park), (2) in Styria (NiedereTauern), and (3) in southern Carinthia (Carnic Alps). From other regions, only isolated or unverified records are reported. In fact, based on an analysis of the spatial and temporal distribution of the information we conclude that there is no population established, presumably even reproductive units are lacking. Instead, the scattered observations rather indicate the presence of single individuals only.
Nestling growth of Great Tits Parus major with comparison among altitudes
Authors: Bordjan Dejan
Published: August 2023

Fledgling mass can have great influence on individual’s life history and reflects the availability and quality of food in the breeding territory. Thus growth curve is used to compare the difference in the quality between different ecological conditions. The aim of the study was to fill the knowledge gap on nestling growth in Great Tit in Slovenia, to determine the influence of altitude on it and to present a tool for estimating age of nestlings and key dates in breeding phenology of Great Tit. Great Tits young were monitored using nest-boxes at three locations between years 2010 and 2012. At two locations nest-boxes were placed on three separate altitudinal belts. Weight growth curve was compared with the curves from other parts of Europe. Growth curve from Slovenia differs in growth parameters from other European populations but falls within their range. Difference in growth parameters betweenseparate populations probably comes from the difference in ecological conditions. When comparing three altitudes weight parameters of hatchlings were similar at lower and middle but different at upper altitudes indicating that weigh growth changes with the altitude. Lower food abundance that comes with rising altitude may be offset by lower competition through lower breeding density (hence similar growth parameters in lower and middle altitude), but not past certain altitude. Weight parameters are usefulwhen comparing different populations, but wing-length is better in determining the age of young in the nest.
Seed banks as a partnership for global plant conservation
Authors: Bavcon Jože , Ravnjak Blanka
Published: August 2023

A seed bank is a collection of plant seeds stored under appropriate conditions in which seeds are periodically checked for their germination ability – viability of seeds. Botanic gardens have been issuing lists of seeds (Index seminum) for several centuries. This old tradition has also encouraged the formation of botanic gardens seed banks. University Botanic Gardens Ljubljana actively works on plant diversity conservation. In 2013, the Garden participated in the collection of seeds for the Millennium Seed Bank in order to contribute to a faster achievement of the goal of seed banking of 25 % of the total world flora. For this reason, in 2013, seeds of 59 target plant species of Slovenian flora (already selected before for routine collection) and seeds of 24 other randomly selected plant species for the Millennium Seed Bank were collected.
Relationship of nuclear genome size, cell volume and nuclei volume in endosperm of Sorghum bicolor
Authors: Kladnik Aleš
Published: August 2023

Endosperm cells of Sorghum bicolor undergo several rounds of endoreplication during seed development, resulting in somatic endopolyploidy with cells containing 3 C to 96 C nuclei (1 C represents the amount of DNA in an unreplicated haploid genome). Cells with higher DNA content are larger and contain larger nuclei. The function of large endosperm cells in Sorghum bicolor is storage of starch that will be used in germination. We analysed the ratios of nuclear genome size and volume of nuclei and cells to determine if karyoplasmic ratio is constant in cells of different endopolyploidy levels. Interestingly, the volume of cells and nuclei increases more than can be expected from the increase in genome size alone. Instead, a constant ratio was observed between genome size and surface of cells and nuclei. However, an isometric relationship was found between volume of nuclei and volume of cells, indicating that karyoplasmic ratio is constant in sense of dimensions of cellular compartments, rather than with nuclear genome size alone.

Published: August 2023

Cyanobacterial blooms in fresh water bodies have a serious negative impact on human, animal and environmental health. The impact of electro-oxidation of water containing Planktothrix rubescens in electrolytic cell equipped with diamond electrodes has been tested. The treatment had an immediate effect on cyanobacterial phycocyanin and chlorophyll fluorescence response and total cell biovolume. Cyano-bacterial number reduced for 80 % 130 h after a single treatment of 500 mL of a water sample through electrolytic cell with a flow rate 1 L/min. Obtained results indicate a great potential of the method for in-lake cyanobacterial control.
Fluorescent markers in microscopy: photophysical characteristics and applications in cell biology
Authors: Bogataj Urban , Štrus Jasna , Žnidaršič Nada , Kreft Marko
Published: August 2023

In the fluorescence microscopy of biological specimens the structures in cells and tissues usually need to be labelled with various fluorescent markers. The three main groups of fluorescent markers are small organic fluorochromes, fluorescent proteins and quantum dots. Fluorescent markers differ according to photophysical properties and binding specificity for the selected target structures in the sample. For the labelling of specific structures with small organic fluorochromes or quantum dots it is usually necessary to conjugate them with target-specific macromolecules. For the labelling with fluorescent proteins it is necessary to introduce a fluorescent protein gene into the observed cells or organism. The most important photophysical properties of fluorescent markers are absorption and emission spectra, Stokes shift, extinction coefficient and quantum yield. Currently, various super-resolution fluorescent microscopy techniques exploit special fluorochromes that enable fluorescence modulation by specific wavelength illumination, to achieve the resolution below the diffraction limit.
Eterična olja s potencialom za zatiranje varoje (Varroa destructor): mehanizmi toksičnosti in negativen vpliv na medonosno čebelo (Apis mellifera)
Authors: Jemec Kokalj Anita , Glavan Gordana
Published: August 2023

Varoja (Varroa destructor) je pomemben dejavnik umiranja čebel, zato njeno učinkovito zatiranje predstavlja enega izmed osrednjih problemov čebelarjenja. Trenutno čebelarji za zatiranje varoje največ uporabljajo sintetične akaricide. Zaradi njihovih negativnih učinkov na čebele ter kemičnih ostankov v čebeljih pridelkih je velik trend k vzpodbujanju uporabe naravnih akaricidov. Med naravne snovi s potencialnim akaricidnim delovanjem sodijo eterična olja in njihove aktivne učinkovine. Med njimi se nekatere, kot je timol, že dlje časa uporabljajo v čebelarstvu. V tem prispevku povzemamo dosedanje znanje o mehanizmih toksičnosti eteričnih olj, s poudarkom na delovanju na živčni in imunski sistem, ter o ostalih vplivih na čebele. Ugotavljamo, da bi lahko bila nekatera eterična olja glede na ugotovljene mehanizme toksičnosti uporabna za zatiranje varoje, vendar pa so njihovi negativni učinki na čebele zelo slabo raziskani. Še posebej so pomembna znanja o njihovem vplivu na imunski odziv, saj so spremembe le tega navedene kot eden izmed potencialnih možnih vzrokov za upad čebeljih družin. Med eteričnimi olji prevladujejo podatki za timol ter njegove pripravke(Apiguard®, Api Life VAR®), precej manj pa je podatkov o drugih pogostih aktivnih učinkovinah eteričnih olj. Zaključujemo, da obstaja potreba po sistematičnem testiranju vplivu akaricidnih eteričnih olj na čebele, s poudarkom na dolgotrajnih izpostavitvahizvedenih po principu aktualnih smernic testiranja strupenosti. Velik izziv za prihodnje raziskave predstavlja optimizacija nanosa in standardizacija uporabe eteričnih olj in njihovih učinkovin v čebelarstvu.
Identification of alien Fallopia taxa using molecular methods
Authors: Strgulc Krajšek Simona , Bjelić Mersiha , Anžlovar Sabina
Published: August 2023

The non-native species of knotweeds (Fallopia sect. Reynoutria) are morphologically very similar and it is often difficult to distinguish between the hybrid F. ×bohemica and parental taxa, F. japonica and F. sachalinensis. To distinguish 30 samples of knotweeds, collected in Slovenia, we used PCR RFLP analysis of the trnK intron of plastid DNA in combination with the amplification of microsatellite nuclear locus KW6, which is a specific diagnostic marker for F. sachalinensis. We established that the combination of both markers unambiguously identifies the following samples: F. japonica (var. japonica), F. sachalinensis and F. ×bohemica. Basedon described molecular markers we confirmed that the maternal parent of the taxon F. ×bohemica was F. japonica for all analysed hybrids. In addition, two species from Fallopia sect. Sarmentosae (F. baldschuanica and F. multiflora) were also analysed.Both could be distinguished from species of Fallopia sect. Reynoutria, but for the discrimination between them, some other markers should be used.

Quasilinear problems with nonlinear boundary conditions in higher-dimensional thin domains with corrugated boundaries
Authors: Nakasato Jean Carlos , Pereira Marcone Corrêa
Published: August 2023

In this work, we analyze the asymptotic behavior of a class of quasilinear elliptic equations defined in oscillating(N+1)\left(N+1)-dimensional thin domains (i.e., a family of bounded open sets fromRN+1{{\mathbb{R}}}^{N+1}, with corrugated bounder, which degenerates to an open bounded set inRN{{\mathbb{R}}}^{N}). We also allow monotone nonlinear boundary conditions on the rough border whose magnitude depends on the squeezing of the domain. According to the intensity of the roughness and a reaction coefficient term on the nonlinear boundary condition, we obtain different regimes establishing effective homogenized limits inNN-dimensional open bounded sets. In order to do that, we combine monotone operator analysis techniques and the unfolding method used to deal with asymptotic analysis and homogenization problems.
TRIM29 knockdown prevented the colon cancer progression through decreasing the ubiquitination levels of KRT5
Authors: Sun Lihui , Wang Dawei , Chen Zhenyu , Zhu Xu
Published: August 2023

To investigate the specific role of TRIM29 in colon cancer progression, bioinformatic analysis was performed on TRIM29. Colon cancer tissues were collected and colon cancer cells were cultured for further experiments. Cell viability and proliferation were determined using CCK-8, colony formation, and EDU staining assays. The mRNA and protein levels of TRIM29 and KRT5 were determined using quantitative real-time PCR and western blotting, respectively. The interaction between TRIM29 and KRT5 was detected using a co-immunoprecipitation (CO-IP) assay. Cycloheximide treatment was performed to analyse the stability of KRT5. TRIM29 was upregulated in colon cancer tissues and cells. TRIM29 knockdown decreased the cell viability and proliferation and ubiquitination levels of KRT5 and enhanced the protein stability and expression of KRT5. The CO-IP assay confirmed that TRIM29 and KRT5 binded to each other. KRT5 knockdown neutralises the inhibitory effect of sh-TRIM29 on colon cancer cell growth and TRIM29 knockdown prevented the proliferation of colon cancer cells by decreasing ubiquitination of KRT5, which enhanced the protein stability and expression of KRT5 in cancer cells. Thus, targeting TRIM29-mediated ubiquitination levels of KRT5 might be a new direction for colon cancer therapy.
Attitude and practice of secondary school students towards voluntary counselling and testing in Mwanza, North-West Tanzania
Authors: Majeshi Joshua , Mweya Clement N.
Published: August 2023

Objectives

Voluntary Counselling and Testing (VCT) has become popular in many parts of the world, especially in Africa, for people to learn about their HIV status and get motivation for positive sexual behaviour change. Our study explored the attitude and practice of secondary school students towards VCT.

Methods

A cross-sectional descriptive study was conducted in Magu, Mwanza, North-West Tanzania. Recorded information included sex, factors promoting or hindering VCT attendance, reasons why attending VCT is necessary, awareness of VCT locations and source of information.

Results

Of the 340 students interviewed, 93.2 % knew that VCT was necessary and had reasons such as getting Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) education, checking HIV status and getting advice if found to be HIV positive. The majority (74.4 %) knew the location of the VCT centres. However, only 20.3 % made use of the VCT services. Those who did not use VCT services had reasons such as time limitations, believing they were not infected and fear of being labelled HIV positive.

Conclusions

Our study shows that most secondary school students know that VCT is necessary and the locations of the VCT centres, but only a few use VCT services. More effort should be put into educating students and society on the importance of using VCT services.
Determining the L2 academic writing development stage: a corpus-based research on doctoral dissertations
Authors: Ahmad Muhammad , Mahmood Muhammad Asim , Siddique Ali Raza
Published: August 2023

This corpus-based research investigates features representing different stages of development in Pakistani academic writing (AW) to determine the stage of Pakistani AW in physical and social sciences. Corpus for this research comprises texts from 80 doctoral dissertations and is analyzed through AntConc after tagging with Multidimensional Analysis Tagger (MAT) and TagAnt. Results show Pakistani AW in both disciplines frequently comprising nouns as pre-modifiers that represent Stage-3. These are lower level features used by the writers developing towards higher levels. Therefore, Pakistani advanced level AW in physical and social sciences is positioned at Stage-3. This suggests that Pakistani writers in these disciplines are operating below the expected developmental level specifically Stage-5. These results are found to oppose the general hypothesis i.e. L2 (English as a second language) academic writers frequently use phrasal features at the advanced level. Consequently, Pakistani AW is concluded to be below the required level of language development.

Authors: Odeh Rasha , Gharaibeh Lobna , Ibrahim Sarah , Alassaf Abeer
Published: September 2023

Objectives

To investigate the prevalence of thyroid autoimmunity and related thyroid disorders among children and adolescents with type 1 diabetes in Jordan.

Methods

In a retrospective study, thyroid stimulating hormone and thyroid hormone (Free T4) levels were measured in 684 children with type 1 diabetes who presented to Jordan University Hospital between January 2012 and February 2021. Anti-thyroid peroxidase (TPOAb) and anti-thyroglobulin (TGAb) antibodies were measured in 526 and 438 subjects with type 1 diabetes, respectively.

Results

681 children were included in the study (52.4 % females, average current age 14.3 years, average age at diagnosis 8.0 years, and average diabetes duration 6.2 years). Of the whole group, 18 children (2.6 %) were diagnosed with subclinical hypothyroidism and 31 children (4.4 %) had overt hypothyroidism. Of those who were tested for TPOAb and TGAb, 22.6 and 23.1 % were positive respectively. Predictors for developing hypothyroidism were female sex and positive antibodies to glutamic acid decarboxylase.

Conclusions

Screening for associated thyroid autoimmunity in children and adolescents with type one diabetes from Jordan is advised with a special focus on females and those with positive antibodies to glutamic acid decarboxylase.
Building a Cultural Learning Resource Based on the Community’s Needs
Authors: Jarusawat Piyapat
Published: September 2023

This study aims to investigate community needs in order to develop the cultural learning resource of Suandok Temple, one of the most important religious monasteries in Chiang Mai, Thailand. This is where, in the Lanna kingdom, now the northern part of Thailand, Lanka Wong Theravada Buddhism was founded. The study is based on interviews, with historical procedures, Shalaginova’s concept of Heritage Interpretation, and Berlo’s SMCR Model of Communication applied to the data analysis. The findings reveal the needs of the community, which can be divided into six themes: (1) important persons to Suandok Temple; (2) outstanding arts and architecture; (3) holy landmark; (4) community center; (5) education hub and tourism; and (6) cultural learning resources. While the first five themes are the contents of the cultural learning resources, the sixth theme offers the guideline and elements, particularly target group, type, and form of presentation, that would be appropriate to cultural learning. With suitable learning resources, users could become aware of and understand the importance of cultural heritage in their community. Consequently, the community as a whole could share a sense of ownership and a determination to maintain, protect, and preserve their cultural heritage.
How intergenerational farmers negotiate their identity in the era of Agriculture 4.0: A multiple-case study in Indonesia
Authors: Widiyanti Emi , Karsidi Ravik , Wijaya Mahendra , Utari Prahastiwi
Published: September 2023

Identity has become a fascinating object of exploration in various aspects of life and work, including farming. Many studies have examined the extent to which farmers reconstruct their identities, and only a limited number have evaluated the forms of negotiation from a communication perspective. Therefore, herein, we addressed this gap by analysing the identity challenges experienced by farmers in the agricultural era 4.0. A comprehensive farmer identity negotiation model was developed by conducting a multi-case study involving millennial and Generation X farmers from different regions in Indonesia. Data were collected through in-depth interviews with 16 farmers who have embraced Agriculture 4.0 across five regencies in Indonesia. The results showed that farmer identity is maintained and built through various processes, including education, outreach, affiliation, and social networking. Farmer identity negotiation also involves self-preparedness, such as developing communication competence and receiving environmental support through social connections, media, and access to information. The process of farmer identity negotiation ultimately leads to the affirmation of identity, manifesting in changes in social roles, lifestyle changes, and improved farming quality. The advent of Agriculture Revolution 4.0 has necessitated the availability of innovative information, provided access to information and communication technology, and spaces for farmer communities to improve their farming competence.
Understanding Humor: Four Conceptual Approaches to the Elusive Subject
Authors: Hietalahti Jarno , Pennanen Joonas
Published: August 2023

This article discusses four ways of understanding the concept of humor: 1) in terms of necessary and sufficient conditions, as 2) a cluster concept, 3) an interpretive concept, and 4) a dual character concept. We peruse both historical and contemporary research on humor, but instead of asking “What is humor?,” we draw conclusions regarding what humor research tells us of the ways to conceptualize humor. The main merits and shortcomings of different approaches are explicated. We suggest that the increased awareness of conceptual options will help the field of humor research to construct ever better theories on the elusive subject matter.
An integrated structure of air spring for ships and its strength characteristics
Authors: Cheng Yuqiang , He Lin , Shuai Changgeng , Cai Cunguang , Gao Hua
Published: August 2023

The increasing demand for the impact resistance of ships entails the excellent impact resistance and deformability of air spring (AS) for ships under high internal pressure. However, an AS of traditional structure is difficult to satisfy such new demand since it is designed with only 10 mm maximum deformation under high internal pressure and strong impact. For this reason, an integrated structure of filament winding reinforced bellows is proposed to ensure the structural strength at the connection of AS bellows and flanges under strong impact and high internal pressure. On this basis, a parameterized design of integrated bellows strength is explored, and we analyzed how the strength of the bellows was affected by the parameters of geometrical structure, material features, and filament winding. As proved in tests, the integrated structural design of the bellows could ensure the strength of AS under strong impact and high internal pressure, and the test result perfectly matches with the calculated strength of the integrated bellows as well as the optimized design.

In this research, an experimental investigation to examine the behavior of piled-raft foundations in loose sand is introduced. A small-scale model was tested in a sandy soil container. Three sensors were fabricated on the pile heads to record the axial load induced by any pile in the group, and the foundation’s settlement was also measured. In addition to experiments for an unpiled raft, model groups for 1 pile, 1 × 2, 1 × 3, 2 × 2, 2 × 3, 3 × 3, 3 × 3 triangle heaps, 4 diamond piles, 5 piles, and 9 circle piles were tested in the lab. The loading test was carried out until a relative pile displacement of 10 % of the length of the raft was passed. It was found that the piled-raft models with piles placed in uniform configurations (2 × 2 and 3 × 3) showed an increase in bearing capacity higher than that of piled rafts with the circle and diamond configurations, but not higher than that of triangular configuration. Also, it was found that when the value of loading was 1,000 N and the pile spacing increased from 2.5d to 3d, the settlement increased from 11 to 13 mm, 9.5 to 11 mm, 8.5 to 10 mm, and 7 to 9 mm for models PR2, PR3, PR4, and PR5 (referring to 2-, 3-, 4-, and 5-piled-raft models), respectively. In practically the whole settlement range tested, the results demonstrated that the contribution of the edge and center piles was considerably higher than that of the single piles underneath the raft. The axial loads carried by the edge and the center piles for the PR9, PR5, and PR3 piled-raft types, respectively, were roughly 40 % and 70 %, 52 % and 70 %, and 20 % and 60 % higher than those for the PR1 pile capacity.

Medium alloy steels are used in several components in the industry where wear and corrosion resistance are required. Different treatments can be used to enhance the surface properties. In this work, the tribological and corrosion behavior of the nitrided and post-oxidized AISI 4140 steel was studied. The samples were plasma nitrided in a 25 %/75 % (N2/H2) gas mixture at 500°C for 15 h. They were oxidized in the same chamber for 1 h in a water steam atmosphere at 400°C. The microstructure of the nitrided and oxidized layer was analyzed using X-ray diffraction (XRD) and scanning electron microscopy. The pin-on-disk tests were performed according to ASTM G99-17, Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus, with a 6-mm diameter alumina ball as counterpart, a sliding distance of 500 m and 1,100 MPa of applied Hertzian pressure. Moreover, reciprocating sliding tests with a stroke length of 5 mm were performed using am AISI 52100 steel ball as a counterpart under a Hertzian pressure of 354 MPa in both dry and lubricated conditions. Salt spray tests following ASTM B117-19, Standard Practice for Operating Salt Spray (Fog) Apparatus, and electrochemical tests in sodium chloride were carried out to evaluate the corrosion behavior. The thickness was 0.5 μm and 3 μm for the oxide layer and the nitrided layer, respectively. Magnetite was detected by XRD. In the pin-on-disk tests conducted under high pressure, the nitrided + oxidized and only nitrided samples presented similar wear resistance. However, the oxide layer allowed a reduction in the friction coefficient in the first cycles with respect to the only nitrided sample in the sliding reciprocating test under low pressure. This behavior was observed in both the dry and lubricated conditions, but it was more noticeable in lubricated ones. Regarding the corrosion behavior, the nitrided + oxidized samples showed better corrosion resistance than the other samples in a chloride solution.

The spinal motor neurons are the only neural cells whose individual activity can be noninvasively identified. This is usually done using grids of surface electromyographic (EMG) electrodes and source separation algorithms; an approach called EMG decomposition. In this study, we combined computational and experimental analyses to assess how the design parameters of grids of electrodes influence the number and the properties of the identified motor units. We first computed the percentage of motor units that could be theoretically discriminated within a pool of 200 simulated motor units when decomposing EMG signals recorded with grids of various sizes and interelectrode distances (IEDs). Increasing the density, the number of electrodes, and the size of the grids, increased the number of motor units that our decomposition algorithm could theoretically discriminate, i.e., up to 83.5% of the simulated pool (range across conditions: 30.5–83.5%). We then identified motor units from experimental EMG signals recorded in six participants with grids of various sizes (range: 2–36 cm2) and IED (range: 4–16 mm). The configuration with the largest number of electrodes and the shortest IED maximized the number of identified motor units (56 ± 14; range: 39–79) and the percentage of early recruited motor units within these samples (29 ± 14%). Finally, the number of identified motor units further increased with a prototyped grid of 256 electrodes and an IED of 2 mm. Taken together, our results showed that larger and denser surface grids of electrodes allow to identify a more representative pool of motor units than currently reported in experimental studies.
A Metatheoretical Review of Cognitive Load Lie Detection
Authors: Neequaye David A.
Published: September 2023

This article examines the idea that cognitive load interventions can expose lies—because lying is more demanding than truth-telling. I discuss the limitations of that hypothesis by reviewing seven of its justifications. For example, liars must suppress the truth while lying, and this handicap makes lying challenging such that one can exploit the challenge to expose lies. The theoretical fitness of each justification is variable and unknown. Those ambiguities prevent analysts from ascertaining the verisimilitude of the hypothesis. I propose research questions whose answers could assist in specifying the justifications and making cognitive load lie detection amenable to severe testing.

General decrease in business activity and revenues of business structures, insufficient level of profitability in the conditions of growing socio-economic turbulence, indicate the need for organizational transformations in management that will provide conditions for improving economic efficiency. The fundamental changes in the business environment caused by the COVID-19 pandemic necessitate a thorough redesign of business processes using reengineering methods. The reengineering algorithm involves consistent assessment of current efficiency, identification of the need for change, design of updated business processes, testing their effectiveness and implementation in the organizational structure. The main areas of reengineering are organizational transformation based on the principles of process approach, total quality management and implementation of digital technologies.

The maximum positive result in the tasks of increasing the mobility of modern industrial production may be possible by using such areas of improvement of factors of production as simplification of labor and expanding the adaptive qualities of the process. In such conditions the principle of universalization in the development of production on the basis of automated control systems is activated and at the same time high levels of automation and integration are guaranteed. The paper proposes an approach to building an algorithm for creating a system for monitoring the parameters of the flexible production process, which leads to maximizing the actual productivity of each object that passes through such a universal organizational and technological system. The process of monitoring a flexible production system exists under the conditions of a set of observations, assessments and forecasts, which can be successful in controllability, continuity, adaptability, targeting, alternative, parallelism and accuracy of its implementation. To achieve this set of actions, there are information systems with means of registration, recording, collection, generalization, analysis, processing, presentation, exchange and storage of production information. In general, the elements of the decision-making process are consistently related mechanisms of transition to probabilistic estimates, which receive information from the system under study. The amount of information for decision-making must be necessary and sufficient, for which the information is universalized and decomposed. An attempt is also made to solve the problem of exclusion, and in case of impossibility - to compensate for the impact of extra-cycle losses on the indicator of actual productivity. There are two ways to do this in a multi-connected organizational and technological system: disabling the influence of subjective factors and using the functional potential of the system.

Indonesian Legal Compliance with International Human Rights Law on Female Genital Mutilation
Authors: Fitriani Nurul Fazrie , Trisnawati Elvita
Published: August 2023

The absence of a law that strictly prohibits female genital mutilation in Indonesia has increased the number of women and girls victimized by this practice. While some communities may justify female genital mutilation as a religious practice, there is no religious justification for this, and neither is Islam, the dominant religion in Indonesia. The United Nations has defined female genital mutilation as a harmful practice that can cause physical and psychological harm to women and girls. Moreover, it is also closely linked with violations of the right to freedom of religion or belief. This qualitative research uses a normative approach by analyzing Indonesian laws related to female genital mutilation and its compatibility with international human rights legal obligations. This research describes Indonesia's role in preventing, addressing, and protecting women and girls who have undergone female genital mutilation. The results show that Indonesian laws on female genital mutilation do not comply with international human rights laws, which prohibit all types of female genital mutilation practices. This research suggests that the Indonesian government should take all measures to eliminate the practice of female genital mutilation through legal action, creating binding and gender-perspective regulations and policies. Eliminating female genital mutilation will contribute to achieving gender equality and women's empowerment in Indonesia, as the country's commitment to the Sustainable Development Goals.
