Published: March 2023

Rehoming is a potentially stressful process for dogs retired from commercial breeding (CB) kennels, as they may struggle to cope with the myriad novel factors associated with transitioning to a home environment. Failure to adapt may increase the risk of an unsuccessful adoption, jeopardizing dog welfare and the benefits of rehoming programs. Little is known about relationships between welfare in the kennel of origin and a dog’s ability to transition to a family home. This study aimed at investigating the welfare states of dogs retiring from CB kennels in relation to varying management practices across kennels, and understanding how behavioral and management factors might be associated with rehoming outcomes. A total of 590 adult dogs from 30 US CB kennels were included in the study. Dog behavioral and physical health metrics were collected through direct observation, while management information was obtained through a questionnaire. One month after adoption, 32 dog owners completed a follow-up questionnaire (CBARQ). A principal component analysis extracted four behavioral components (PCs) which included food interest, sociability, boldness, and responsiveness. Factors such as sex, housing, breed, and the number of dogs per caretaker were reported as significant sources of variation for some of those PC scores (p<0.05). For instance, lower dog to caretaker ratio was linked to better health, sociability, and food interest scores. Significant relationships were also found between in-kennel PC scores and CBARQ scores (p<0.05). Most interestingly, higher levels of sociability in the kennel were associated with lower levels of social and non-social fear, and higher trainability after rehoming. Overall, dogs were found to be physically healthy, and a moderate proportion showed fearful responses toward either social or non-social stimuli. Results suggest that a comprehensive behavioral assessment of rehoming candidates while in the kennel may help identify dogs that may have more difficulty coping during rehoming. The implications for developing management strategies and necessary interventions that support positive dog welfare outcomes within the kennel and when rehomed are discussed.

Published: March 2023

Objectives

In the current study, we examined the relationship between differentiation of self (DoS) and key relationship functioning variables among couples. This is the first study to test such relationships using a cross-cultural longitudinal approach (i.e., samples from Spain and the U.S.) while controlling for stressful life events–a key theoretical construct in Bowen Family Systems Theory.

Methods

A sample of 958 individuals (n = 137 couples from Spain, and n = 342 couples from U.S.) was used in cross sectional and longitudinal models to analyze the effects of a shared reality construct of DoS on anxious attachment, avoidant attachment, relationship stability, and relationship quality while considering gender and culture.

Results

Our cross-sectional results indicated that men and women from both cultures experienced an increase in DoS over time. DoS predicted increased relationship quality and stability and decreased anxious and avoidant attachment in U.S. participants. Longitudinally, DoS predicted increased relationship quality and decreased anxious attachment for Spanish women and men, while it predicted greater relationship quality and stability and decreased anxious and avoidant attachment of U.S. couples. Implications of these mixed findings are discussed.

Conclusions

Higher levels of DoS are linked with a better couple relationship across time, despite varying levels of stressful life events. Although some cultural differences regarding the links between relationship stability and avoidant attachment exist, this positive link between differentiation and the couple relationship is mostly consistent across the U.S. and Spain. The implications and relevance for integration into research and practice are discussed.

Published: March 2023

Background

Evidence on tobacco use among indigenous communities is scarce with available literature based either on a specific region or a particular tribe. Considering the large tribal population in India, it is pertinent to generate evidence on tobacco use among this community. Using nationally representative data, we aimed to estimate the prevalence of tobacco use and assess its determinants and regional variations among older tribal adults in India.

Methods

We analysed data from Longitudinal Ageing Study in India (LASI), wave-1 conducted in 2017–18. A sample of 11,365 tribal individuals aged ≥ 45 years was included in this study. Descriptive statistics was used to assess the prevalence of smokeless tobacco (SLT), smoking, and any form of tobacco use. Separate multivariable regression models were executed to assess the association of various socio-demographic variables with different forms of tobacco use, reported as adjusted odds ratio (AOR) with 95% confidence interval.

Results

The overall prevalence of tobacco use was around 46%, with 19% of smokers and nearly 32% smokeless tobacco (SLT) users. Participants from the lowest MPCE quintile group had a significantly higher risk of consuming (SLT) [AOR: 1.41 (95% CI: 1.04–1.92)]. Alcohol was found to be associated with both smoking [AOR: 2.09 (95% CI: 1.69–2.58)] and (SLT) [AOR: 3.05 (95% CI: 2.54–3.66)]. Relatively higher odds of consuming (SLT) were associated with the eastern region [AOR: 6.21 (95% CI: 3.91–9.88)].

Conclusion

This study highlights the high burden of tobacco use and its social determinants among the tribal population in India, which can help tailor anti-tobacco messages for this vulnerable population to make tobacco control programs more effective.
Barriers and facilitators of vaccine hesitancy for COVID-19, influenza, and pertussis during pregnancy and in mothers of infants under two years: An umbrella review
Authors: Nichol Bethany , McCready Jemma Louise , Steen Mary , Unsworth John , Simonetti Valentina , Tomietto Marco
Published: March 2023

Background

Vaccination during pregnancy has been repeatedly demonstrated to be safe and effective in protecting against infection and associated harms for the mother, developing baby, and subsequent infant. However, maternal vaccination uptake remains low compared to the general population.

Objectives

An umbrella review to explore the barriers and facilitators to Influenza, Pertussis and COVID-19 vaccination during pregnancy and within 2 years after childbirth, and to inform interventions to encourage uptake (PROSPERO registration number: CRD42022327624).

Methods

Ten databases were searched for systematic reviews published between 2009 and April 2022 exploring the predictors of vaccination or effectiveness of interventions to improve vaccination for Pertussis, Influenza, or COVD-19. Both pregnant women and mothers of infants under two years were included. Barriers and facilitators were organised using the WHO model of determinants of vaccine hesitancy through narrative synthesis, the Joanna Briggs Institute checklist assessed review quality, and the degree of overlap of primary studies was calculated.

Results

19 reviews were included. Considerable overlap was found especially for intervention reviews, and the quality of the included reviews and their primary studies varied. Sociodemographic factors were specifically researched in the context of COVID-19, exerting a small but consistent effect on vaccination. Concerns around the safety of vaccination particularly for the developing baby were a main barrier. While key facilitators included recommendation from a healthcare professional, previous vaccination, knowledge around vaccination, and communication with and support from social groups. Intervention reviews indicated multi-component interventions involving human interaction to be most effective.

Conclusion

The main barriers and facilitators for Influenza, Pertussis and COVID-19 vaccination have been identified and constitute the foundation for policy development at the international level. Ethnicity, socioeconomic status, concerns about vaccine safety and side effects, and lack of healthcare professionals’ recommendations, are the most relevant factors of vaccine hesitancy. Adapting educational interventions to specific populations, person-to-person interaction, healthcare professionals’ involvement, and interpersonal support are important strategies to improve uptake.
‘In it for the money, not the science’?1 Problems and potentials of stormchasing media
Authors: Beattie Melissa Anne
Published: March 2023

Stormchasing is the practice of following storm systems and storms in progress over land. Though a critical part of research into meteorology by providing on the ground data for comparison with remote radar, satellite and/or other mechanized sources, stormchasing has more recently become part of the journalistic and digital media landscape. Despite its importance, stormchasing media has not been studied as either a media form and industry in its own right or in regard to reception by its audience. This article will begin to redress this absence through a pilot study encompassing the analysis of stormchasing texts, industrial context(s) and audience reception.
Modern vocal pedagogy: Investigating a potential curricular framework for training popular music singing teachers
Authors: Sear Joanna
Published: March 2023

This study explores the content and pertinence of a curricular framework for training popular music (PM) singing teachers. The author conducted three extensive literature review studies over two years via an action research framework to investigate common areas of interest for potential pedagogical strategy. She developed a draft curricular topic framework, incorporating five PM-specific areas: vocal health and hygiene, PM stylistic advice, microphones/audio technology, resonance and breathing technique. Five international PM voice teaching representatives took part in the research as focus group participants and provided feedback on the curriculum content. Data from this feedback were analysed in an iterative cycle process and adjustments suggested. Findings from this study indicate that such a curriculum would be both necessary and timely. Suggestions were made to amend some elements and to place greater emphasis on aesthetic artistry, cultural context and emotional intent.
Different Ways to Die: Cell Death Pathways and Their Association With Spinal Cord Injury
Authors: Guha Lahanya , Singh Nidhi , Kumar Hemant
Published: March 2023

Cell death is a systematic/nonsystematic process of cessation of normal morphology and functional properties of the cell to replace and recycle old cells with new also promoting inflammation in some cases. It is a complicated process comprising multiple pathways. Some are well-explored, and others have just begun to be. The research on appropriate control of cell death pathways after acute and chronic damage of neuronal cells is being widely researched today due to the lack of regeneration and recovering potential of a neuronal cell after sustaining damage and the inability to control the direction of neuronal growth. In the progression and onset of various neurological diseases, impairments in programmed cell death signaling processes, like necroptosis, apoptosis, ferroptosis, pyroptosis, and pathways directly or indirectly linked, like autophagy as in nonprogrammed necrosis, are observed. Spinal cord injury (SCI) involves the temporary or permanent disruption of motor activities due to the death of a neuronal and glial cell in the spinal cord accompanied by axonal degeneration. Recent years have seen a significant increase in research on the intricate biochemical interactions that occur after a SCI. Different cell death pathways may significantly impact the subsequent damage processes that lead to the eventual neurological deficiency after an injury to the spinal cord. A better knowledge of the molecular basis of the involved cell death pathways might help enhance neuronal and glial survival and neurological deficits, promoting a curative path for SCI.

Authors: Talal Lillian A. , Wang Huipei , Williams Brian T. , Morris Matthew J. , Horvath Peter J.
Published: March 2023

Background
To determine the acute effects on postprandial lipemia and glycemia by supplementing a high-fat meal with either white button (WB) or shiitake (SH) mushroom powder.

Methods
Nine healthy participants (4-male, 5-female, 23.3±1.3 years, 17.8±6% body fat, 56.2±11.4kg fat free mass) consumed a control hamburger. At one-week intervals, after consumption of a control meal, participants consumed hamburgers in random order, supplemented with 14g of either WB or SH mushroom powder. Peripheral blood for lipids (triglycerides, high-density lipoprotein HDL, low-density lipoprotein LDL), and glucose was obtained at baseline (t=0 hours) and postprandially every two hours for six hours. Data were analyzed using linear mixed effects models.

Results
Lower LDL levels were observed for both SH and WB burgers compared to the control burger (p=0.0007) over the six-hour period. Mushroom powder content did not alter triglyceride, HDL, or glucose levels. Gender affected triglyceride and HDL levels over the treatment course. Triglyceride levels were higher in males (p=0.0084), and HDL levels were lower in females (p=0.0005). Triglyceride and glucose levels were higher, (p< 0.001 and p< 0.0001 respectively), during the postprandial time course (t=0, 2, 4, 6 hours).

Conclusions
Supplementing SH or WB mushrooms during a high-fat meal may lower serum LDL levels.

Authors: Bakhshwin Ahmed , Robertson Jessica , Sarwate Mrinal , Roberts Daniel
Published: March 2023

Recently, the use of immunotherapy has increased substantially for the treatment of several malignancies. It is associated with several gastrointestinal adverse events; however, severe complications such as intestinal perforation are rare. We present a 75-year-old man with metastatic melanoma, presented with profuse diarrhea and abdominal pain, after ipilimumab and nivolumab administration. Shortly after, he developed fulminant colitis and intestinal perforation and was found to have concurrent Rosai-Dorfman disease of pericolonic lymph nodes. With the increasing use of immunotherapy, reporting of serious adverse events and their mimics is essential. In addition, further studies are required to investigate whether an association exists between Rosai-Dorfman disease and immunotherapy.

Published: March 2023

Actinomyces israelii is a filamentous, gram-positive anaerobic bacterium commonly found in the upper gastrointestinal tract, colon, and female genital tract. Rarely, actinomycosis can infect the pancreas most commonly after pancreatic instrumentation, often mimicking malignancy. We describe a case of a 26-year-old woman who presented with epigastric abdominal pain and nausea without prior pancreatic instrumentation. Abdominal imaging demonstrated a mass in the pancreatic head with fine-needle biopsy revealing Actinomyces. The patient was successfully treated with long-term antibiotic therapy resulting in resolution of the mass. Our case emphasizes the importance of considering nonmalignant etiologies in the differential diagnosis of pancreatic masses.
Preserving home: resistance to cholera sanitation procedures in Egypt
Authors: Schultz Alexandra , Hipwood Tara , Lee Seyeon
Published: March 2023

Less than a year after the British occupation of Egypt in 1882, cholera struck in late June 1883. The country experienced three subsequent epidemics in 1895–6, 1902 and 1947. Over the course of these four epidemics, the British colonial government and its agencies closed access to water resources, forcibly entered homes and removed sick people from their families, ostensibly to prevent the spread of the disease. Concerns for the public’s health served as a convenient pretext to practice emergency sanitary measures which were cheaper than comprehensive reform and reinforced the British colonial view of Egyptians as inferior to European colonisers. Public health measures also supported subsidiary goals to control water, control bodies and police the private spaces of the home. The British characterisation of Egyptian water practice and home sanitation as unclean, even dirty, underpinned these methods, even though proper sanitation had always been an important part of Egyptian and Ottoman culture. In response, people resisted the home invasions and forced family separations. People lied, eluded, spread rumours, persuaded others to lie, fled their homes and concealed family members. Evidence includes government reports, Egyptian daily newspapers, photographs, plans and memoirs. Although these are documents produced by government officials and members of Egypt’s elite, they include evidence of substantial public resistance to cholera policing. They can be read against the grain to reveal the power of this resistance.

Development of an adaptive coaxial concrete rheometer and rheological characterisation of fresh concrete
Authors: Josch Sebastian , Jesinghausen Steffen , Schmid Hans-Joachim
Published: March 2023

The accessibility to rheological parameters for concrete is becoming more and more relevant. This is mainly related to the constantly emerging challenges, such as not only the development of high-strength concretes is progressing very fast but also the simulation of the flow behaviour is of high importance. The main problem, however, is that the rheological characterisation of fresh concrete is not possible via commercial rheometers. The so-called concrete rheometers provide valuable relative values for comparing different concretes, but they cannot measure absolute values. Therefore, we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement of fresh concrete with particles up to

d

max

=
5.5

mm

{d}_{{\rm{\max }}}=5.5\hspace{.5em}{\rm{mm}}

. The comparison of the ACCR with a commercial rheometer showed very good agreement for selected test materials (Newtonian fluid, shear thinning fluid, suspension, and yield stress fluid), so that self-compacting concrete was subsequently measured. Since these measurements showed a very high reproducibility, the rheological properties of the fresh concrete could be determined with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified Bingham (MB) models) were also tested for their applicability, with the Bingham and the modified Bingham model proving to be the best suitable ones.

Published: March 2023

Non-spatial structure of forest is an important aspect for harvesting regimes, silvicultural treatments, and ecosystem service provisions. In this pursuit, the present research envisaged the measurement of the crown and diameter structure ofPinus massonianaLamb. Specifically, the forests were assessed with a range of nine cities in Hunan Province, China. The gradient boosting model was used to quantify the contribution of seven drivers of the diameter at breast height (DBH) diversity. Moreover, the relationship between the crown structure and DBH/tree height was explored using TSTRAT and path analysis. The Anderson–Darling test results indicated that DBH distributions of nine cities did not occur from the same population, the maturing diameter distribution was the main type among the cities. Slope direction was identified as the most impacted factor affecting the DBH diversity, followed by landform and stand density. The vertical stratification indicated a simple vertical structure, and the relationship between the DBH/tree height and crown structure changed in different stages, which reflected the competition mechanism and adaption strategy in the forest. Our study summarized the diameter and crown structure of pureP. massonianaforest in Hunan province, which can provide valuable information in the forest management, planning, and valuation of ecosystem services.
Hyperspectral imaging-based cutaneous wound classification using neighbourhood extraction 3D convolutional neural network
Authors: Cihan Mücahit , Ceylan Murat
Published: March 2023

Objectives

Hyperspectral imaging is an emerging imaging modality that beginning to gain attention for medical research and has an important potential in clinical applications. Nowadays, spectral imaging modalities such as multispectral and hyperspectral have proven their ability to provide important information that can help to better characterize the wound. Oxygenation changes in the wounded tissue differ from normal tissue. This causes the spectral characteristics to be different. In this study, it is classified cutaneous wounds with neighbourhood extraction 3-dimensional convolutional neural network method.

Methods

The methodology of hyperspectral imaging performed to obtain the most useful information about the wounded and normal tissue is explained in detail. When the hyperspectral signatures of wounded and normal tissues are compared on the hyperspectral image, it is revealed that there is a relative difference between them. By taking advantage of these differences, cuboids that also consider neighbouring pixels are generated, and a uniquely designed 3-dimensional convolutional neural network model is trained with the cuboids to extract both spatial and spectral information.

Results

The effectiveness of the proposed method was evaluated for different cuboid spatial dimensions and training/testing rates. The best result with 99.69% was achieved when the training/testing rate was 0.9/0.1 and the cuboid spatial dimension was 17. It is observed that the proposed method outperforms the 2-dimensional convolutional neural network method and achieves high accuracy even with much less training data. The obtained results using the neighbourhood extraction 3-dimensional convolutional neural network method show that the proposed method highly classifies the wounded area. In addition, the classification performance and the2computation time of the neighbourhood extraction 3-dimensional convolutional neural network methodology were analyzed and compared with existing 2-dimensional convolutional neural network.

Conclusions

As a clinical diagnostic tool, hyperspectral imaging, with neighbourhood extraction 3-dimensional convolutional neural network, has yielded remarkable results for the classification of wounded and normal tissues. Skin color does not play any role in the success of the proposed method. Since only the reflectance values of the spectral signatures are different for various skin colors. For different ethnic groups, The spectral signatures of wounded tissue and the spectral signatures of normal tissue show similar spectral characteristics among themselves.

Published: March 2023

The structure of the bamboo node obviously differs from that of the internode and largely affects the mechanical properties of bamboo. However, the node structure of moso bamboo, an important economic and ecologic bamboo species, was still unclear. Thus, in this study, the 3D structural changes of the vascular bundle (VB) in the moso bamboo node were visualized and quantified. The compressive properties and failure mechanisms of the bamboo node were discussed based on the structural changes. The results showed that the horizontal VB in bamboo node was classified into three types: branching, cross-linking, and thickening. The cross-sectional area of the vertical VB in bamboo node increased, and the vertical VBs shifted to the outer side after passing through the node. Due to the “wire hoop” effect of the horizontal VBs, the longitudinal compressive strength of the node was greater than that of the internode. The deflection of VBs caused slippage between VBs and resulted in the decrease of the node’s transversal compressive strength. This research provided key information for a deeper understanding of the structure and mechanical properties of bamboo for potential applications.

Published: March 2023

The construction of Samoan identity in New Zealand is shaped by complex historical and contemporary social, economic, cultural and political factors. In addition, New Zealand-born Samoans are negotiating an ethnic and identity that incorporates their experience with the intergenerational stories and cultural knowledge of their ancestors. Such cultural and identity negotiations are occurring through the practice of Siva Samoa, Samoan dance. Using Multimodal (Inter)action Analysis we conduct a micro analysis of two excerpts of video data involving female Samoan dancers rehearsing for a dance showcase. Vertical identity production (Norris, S. (2011). Identity in (inter)action: introducing multimodal (inter)action analysis. Berlin and Boston: Mouton: 179, 2020:85) is used as a framework to analyze the multiple layers of discourse within each site of engagement that shape the construction of Samoan Identity for the participants involved.

The continuous increase in communication capacity is accompanied by an increase in transmission frequency, which creates new demands on the transmission efficiency in modern. Signal relay transmission can increase the transmission distance, however, conventional repeaters relay the signal in a specified direction, which is difficult to accommodate communication when a receiving device suddenly appears around the repeater. In this work, we propose a new signal transmission repeater, which is implemented by an adaptively reconfigurable multi-beam reflective metasurface based on multispectral detection. The reconfigurable metasurface with varactor diodes is designed and the mapping of phase profiles to voltages is established by polynomial fitting method. Visual, laser, infrared and ultrasonic detectors are used to detect targets in different scenarios. Thus, the detection information is fed back to the reconfigurable metasurface for adaptively multi-beam switching. As verification, the adaptive metasurface repeater was fabricated and measured to verify our design. All the results exhibit consistency with theoretical design. Importantly, this work paves a new way to intelligent metasurfaces and may find applications in intelligent communications, smart home, etc.
A novel design of impeller cavity pre-swirl system for efficient supercharging and low power consumption
Authors: Lian Wenlei , Zhu Yu , Chen Xiaoming , Zhou Zhixiang , Huang Yong
Published: March 2023

A design for a turbine pre-swirl system with impeller cavity is proposed to improve the quality of cooling air supplied to the turbine blades of an aeroengine. Impeller cavity is analyzed in order to increase the system pressure ratio with a low system power consumption at the system outlet. Theoretical and numerical investigation are used to investigate the flow characteristics in an impeller cavity pre-swirl system. The conclusions in this study indicate that the impeller structure can increases the pressure ratio by changing the power consumption and distribution of the absolute velocity in the impeller cavity and system outlet. To obtain high pressure ratio and low power consumption, the impeller should have a structure with a high outlet installation radius and low outlet angle. The highest increase in the pressure ratio compared with the empty cavity pre-swirl system is 6.4% and the corresponding increase in the power consumption is 2620 W.
Loading Variable Effects on Fatigue Behavior of Wood Flour High-Density Polyethylene Composites
Authors: Mokhtarnia Babak , Layeghi Mohammad
Published: March 2023

This article investigated the flexural fatigue properties of wood flour high-density polyethylene composites. Composites with polymer matrix were fabricated and subjected to three-point bending fatigue tests. Cyclic loads were performed at different loading ratios (0.1 and 0.3) and frequencies (0.9 and 5.2 Hz) to determine the effect of these parameters on the fatigue behavior of composite samples. Cyclic stress amplitude versus number of cycles to failure curves of experiments were plotted and compared. For safe fatigue design and material reliability index, a 95 % confidence interval band of fatigue lives were plotted. Stiffness reduction approach was used to evaluate and monitor damage evolution. An experiment like this provides insight into fatigue properties of wood-fiber plastic composites to improve the life of parts under cyclic loading.

Obesity is associated with metabolic disorders and chronic inflammation. However, the obesity‐associated metabolic contribution to inflammatory induction remains elusive. Here, we show that, compared with lean mice, CD4+ T cells from obese mice exhibit elevated basal levels of fatty acid β‐oxidation (FAO), which promote T cell glycolysis and thus hyperactivation, leading to enhanced induction of inflammation. Mechanistically, the FAO rate‐limiting enzyme carnitine palmitoyltransferase 1a (Cpt1a) stabilizes the mitochondrial E3 ubiquitin ligase Goliath, which mediates deubiquitination of calcineurin and thus enhances activation of NF‐AT signaling, thereby promoting glycolysis and hyperactivation of CD4+ T cells in obesity. We also report the specific GOLIATH inhibitor DC‐Gonib32, which blocks this FAO‐glycolysis metabolic axis in CD4+ T cells of obese mice and reduces the induction of inflammation. Overall, these findings establish a role of a Goliath‐bridged FAO‐glycolysis axis in mediating CD4+ T cell hyperactivation and thus inflammation in obese mice.

U teorijskom dijelu rada raspravlja se o određenju paronima i predstavljaju rezultati malobrojnih dosadašnjih istraživanja. U drugome dijelu rada prikazano je istraživanje u kojemu je sudjelovalo 109 ispitanika. Kao instrument poslužio je upitnik koji se sastojao od dva zadatka nadopunjavanja rečenica. Svaki je zadatak sadržavao po deset rečenica s glagolskim paronimnim parnjacima (korijenskim i prefiksalnim). Prikazani su rezultati svih ispitanika, a zatim su se odgovori raščlanjivali prema trima kriterijima (obrazovanje, materinsko narječje i odraz jata). Cilj je istraživanja utvrditi odstupaju li ispitanici od norme hrvatskoga standardnog jezika pri upotrebi paronimnih glagola, odnosno prepoznaju li razliku između paronimnih parnjaka te služe li se odgovarajućim parnjakom u zadanom kontekstu. Rezultati istraživanja potvrdili su hipotezu da ispitanici bolje razlikuju prefiksalne paronime. Lošiji su rezultat ispitanici postigli u zadatku u kojemu se tražilo da prepoznaju korijenske paronimne parnjake u određenom kontekstu. Rezultati istraživanja potvrđuju Tafrin (2003) zaključak o nužnosti izrade rječnika paronima u kojemu bi se nalazilo objašnjenje paronima i njihove tvorbe te popis najčešćih pogrješaka kod govornika.

U radu se obrađuju morfološki oblici krša u toponimiji u naselju Dubrava u Poljicima u omiškom zaleđu. Prikupljeni su toponimi uspoređeni s dostupnim zemljovidima te su toponomastički obrađeni s obzirom na motivaciju njihova nastanka. Sveukupno je prikupljeno i analizirano 78 toponima. Obrađeni su toponimi koji se odnose na oblik tla (npr. Brdo, Kuk, Ober), oni motivirani terminima metaforičnog postanja (npr. Daske, Sedlo, Ždrilo), koji se odnose na oblik i površinska svojstva tla (npr. Crveni klanac, Duga bađina, Lipe rudine), sastav tla (npr. Bilaje, Ljut, Sedra), na njegov položaj i odnos prema drugim toponimima (npr. Dočići, Jezerine, Mali rat), koji su motivirani biljnim (npr. Dračeva rudina, Komorikov brig) i životinjskim svijetom (npr. Orlov kuk, Vučja kamenica), potom vjerskim životom zajednice (npr. Antonska jezera, Ivanjske stine) te one s antroponimnom sastavnicom (npr. Petrov dolac). Prikupljeni su toponimi uglavnom jednorječni. Među dvorječnima, morfološke oblike tla nalazimo među toponimijskim metaforama, toponimima koji označuju oblik i površinska svojstva tla, onima koji se odnose na sastav i osobitosti tla ili vode, određenima položajem i odnosom prema drugim toponimima ili predjelima, motiviranima nazivima biljaka i biljnih zajednica, nazivima životinja i zoonimima, odnosom prema postojećim crkvenim građevinama ili njihovim posjedima te antroponimima. Prikupljeni toponimi u kojima su odraza našli apelativi za geomorfološke oblike krškoga dubrovskoga područja najvećim su dijelom slavenskoga podrijetla. Apelativ stranoga podrijetla koji se odrazio u analiziranim toponimima primili smo posredstvom dalmatskoga (Makirina).
Encyklopedyzm jako sposób myślenia
Authors: Rogić Musa Tea
Published: March 2023

W artykule zostanie przedstawiona interpretacja metodologiczna i narracyjna Leksykonu tradycji chorwackich Joanny Rapackiej z perspektywy nowoczesnego gatunku encyklopedycznego.Jego podstawową jest tezą jest, że Leksykon, niezależnie od tytułu, stanowi – zgodnie ze swoją wewnętrzną koncepcją i realizacją tekstową – przykład hybrydowego gatunku nowoczesnej autorskiej encyklopedii i syntezy historycznokulturowej oraz – biorąc pod uwagę cechy stylu leksykograficznego autorki – przykład tradycji encyklopedycznej, którą rozpoczął i eseistycznie realizował Miroslav Krleža. Konkretne cechy leksykograficznego stylu Joanny Rapackiej zostaną ocenione zgodnie z tradycyjną metodologią nowoczesnej encyklopedii chorwackiej i zasadami zawodu leksykografa przedstawionymi we wczesnej fazie tworzenia (chorwackiej i jugosłowiańskiej) encyklopedii narodowej, zaraz po założeniu Instytutu Leksykograficznego. Intencją i celem niniejszej pracy jest udowodnienie, że Leksykon jest podwójnie udanym projektem. Na poziomie faktograficznym jest on reprezentatywny dzięki profesjonalnej rekonstrukcji danych, osób, terminów i zjawisk z przeszłości, historii i historiografii Chorwacji. Natomiast na poziomie gatunkowym z powodzeniem odpowiada najlepszej tradycji nowoczesnego encyklopedyzmu, w środowisku chorwackim ugruntowanego dzięki wizji Krležy i jego rozumieniu charakteru pracy leksykograficznej. Synergię Leksykonu Rapackiej z chorwacką tradycją encyklopedyzmu drugiej połowy XX wieku, zwłaszcza w obszarze prezentacji historii kultury i literatury w encyklopediach, uznaję za przekonujący dowód wzorcowej erudycji i naukowego ugruntowania autorki w szeroko rozumianym Leksykonie – skarbcu chorwackich studiów i wiedzy historiograficznej.
„Aber wohin konnte man gehen?“ Interkulturelle Räume in Fred Wanders Exilant*innen-Roman Hôtel Baalbek (1991)
Authors: Hermes Stefan
Published: March 2023

Der Aufsatz untersucht, auf welche Weise in Fred Wanders autobiographisch gefärbtem Roman Hôtel Baalbek (1991) interkulturelle Räume inszeniert werden. Dabei ist es von besonderem Belang, dass der Text diverse positiv konnotierte Elemente des mediterranistischen Diskurses aufgreift, sie aber ins Negative wendet, um so die katastrophale Lage seiner Protagonist*innen zu veranschaulichen: Diese hat es zu Beginn der 1940er Jahre auf der Flucht vor Hitlers Terrorregime nach Marseille verschlagen, wo sie sich verzweifelt und überwiegend vergeblich darum bemühen, nach Amerika weiterreisen zu können. Angesichts dessen leuchtet es ein, dass der Roman eine Reihe nicht zuletzt touristischer Topoi und Motive dergestalt variiert, dass von den Verheißungen des Interkulturellen kaum etwas übrigbleibt.
Prostorna dimenzija depopulacije Hrvata u Bosni i Hercegovini
Authors: Bašić Ksenija , Malović Martin
Published: March 2023

Od prvog austro-ugarskog popisa stanovništva na području Bosne i Hercegovine najveći udio Hrvata u ukupnom stanovništvu utvrđen je 1948. godine, a otada se, zbog intenzivnog iseljavanja, svakim sljedećim popisom smanjivao. Unatoč tome broj Hrvata kontinuirano je rastao do 1971. godine jer je do tada visoki prirodni priraštaj pokrivao demografske gubitke uzrokovane migracijom, no nakon toga iseljavanje postaje determinirajuća sastavnica ukupnoga kretanja. U ratu, devedesetih godina, poginulo je između osam i devet tisuća Hrvata, no znatno su veći demografski gubici nastali prisilnom migracijom. Od 312 000 izbjeglih Hrvata u zemlju ih se vratilo manje od 30 %, a toliko je i raseljenih koji su se vratili u svoje domove. Kao posljedica toga iz nekih su dijelova Bosne i Hercegovine Hrvati potpuno nestali, oko polovine ih je koncentrirano u zapadnoj Hercegovini i Završju, dio u hrvatskim enklavama u središnjoj Bosni i Bosanskoj Posavini dok ostali čine manjinu uglavnom u većinski bošnjačkim područjima. Odljevom stanovništva u optimalnoj radnoj i reproduktivnoj dobi ubrzano je demografsko starenje i smanjen bioreprodukcijski potencijal stanovništva te nakon kratkotrajne natalitetne kompenzacije u prvim poratnim godinama dolazi do pada rodnosti i povećanja smrtnosti. Loša ekonomska situacija i politička nestabilnost u poslijeratnom razdoblju doveli su do pada fertiliteta i rastućeg trenda iseljavanja, naročito nakon pristupanja Hrvatske Europskoj uniji. Sveukupno se broj Hrvata u Bosni i Hercegovini od 1991. do 2013. godine smanjio za 216 000, odnosno 28,4 %, a trend smanjenja se nastavlja. Najnepovoljniju demografsku perspektivu imaju Hrvati u područjima gdje ih je najmanje – Republici Srpskoj i pretežno bošnjačkim kantonima. Povoljnija obilježja i potencijal za revitalizaciju imaju u središnjoj Bosni, a relativno najbolja je demografska slika Hrvata u zapadnoj Hercegovini i Završju – najvećem kontinuiranom području s većinskim hrvatskim stanovništvom. Međutim, uz aktualne negativne trendove jedino hitna provedba odgovarajuće razvojne i populacijske politike može osigurati dugoročnu opstojnost i konstitutivnost Hrvata u Bosni i Hercegovini.
Višekriterijsko ispitivanje učinka nastave na daljinu tijekom prve pandemijske godine COVID-19
Authors: Cindrić Josip
Published: March 2023

Jedna od primarnih pretpostavki postdigitalnih teorija je nerazdvojivost tehnologije i digitalnih medija od društvenih i humanih aktivnosti. Otvorena ostaju pitanja definiranja humanog identiteta, posebice u okvirima obrazovanja. Ovaj rad prikazuje prikupljene informacije o nastavi na daljinu tijekom prve pandemijske godine od globalnog zatvaranja u ožujku 2020. do kraja ljetnog semestra iste godine. Prije, tijekom i nakon prve pandemijske godine i nastave na daljinu za studente Odjela za izobrazbu učitelja i odgojitelja Sveučilišta u Zadru, pratilo se nekoliko globalnih parametara kod studenata s ciljem poboljšanja izvedbe nastave na daljinu. 311 (47% od ukupno upisanih) studenata svih studijskih godina na Odjelu za izobrazbu učitelja i odgojitelja (Sveučilište u Zadru) participiralo je u istraživanju. Korišteni su upitnici o organizaciji nastave na daljinu, teškoće u koncentraciji i motivaciji, opterećenost nastavom na daljinu, stres vezan uz nastavu na daljinu , stav o nastavi na daljinu općenito. Rezultati na početku pandemije su pokazali umjerenu razinu teškoća u koncentraciji i motivaciji i opterećenosti nastavom, nešto pozitivnije procjene organizacije nastave na daljinu i optimizma, dok je najviša bila procjena stresa vezanog za nastavu na daljinu a najniža procjena nastave na daljinu općenito kao alternative klasičnoj nastavi. Utvrđene su razlike u procjeni teškoća u koncentraciji i motivaciji, opterećenosti, procjeni stresa i akademskog postignuća s obzirom na studijsku godinu. Na kraju prve pandemijske godine porastao je postotak studenata koji su bili redovitiji na nastavi, kao i onih koji smatraju da će im uspjeh biti bolji, povećale se vrijednosti za procjenu organizacije, motivaciju, stav prema nastavi na daljinu kao alternativi klasičnoj nastavi, te smanjio strah od ispita (zadovoljstvo provedbom ispita 3.94).
‘Dios perdone a Castillejo, que bien habló destas trovas’
Authors: Gamba Corradine Jimena
Published: March 2023

En este artículo analizo las ideas poéticas y amorosas en dos poemas de Gregorio Silvestre (1520-1569), la Visita de amor y la Residencia de Amor, cuya escritura posiblemente estuvo separada por una década (c. 1555-1565). Si en la Visita Silvestre bebe del debate entre lírica tradicional y lírica italianizante, expuesto en textos como la Reprehensión de Cristóbal de Castillejo, en la Residencia, mediante un juego intertextual con el Infierno de amor de Garci Sánchez de Badajoz, el poeta critica el tipo de amor sufriente propio de los poetas de cancionero más representativos y defiende un proyecto poético y amatorio de tendencia racional y platonizante, que se concreta especialmente en las figuras de Jorge de Montemayor y Luis Barahona de Soto. Las posiciones de Silvestre en ambos textos no solo dan cuenta de su evolución poética, sino también de la ambigüedad y diversificación que podían suscitar en un poeta de la mitad de siglo xvi los debates entre lírica tradicional y lírica petrarquista.
