Published: October 2023

Coconut fiber has excellent permeability and water retention properties, making it a popular choice as an organic substrate for cultivation in the field of facility agriculture. To investigate the dielectric properties of coconut fiber and develop an accurate measurement model for dielectric water content, a vector network analyzer was used to measure the relative dielectric permittivity of coconut fiber and study the dielectric properties of coconut fiber under different volumetric water contents, temperatures, and salinities. The results indicated that the relative dielectric permittivity of the coconut fiber increased with increasing volumetric water content. The optimal frequency range for measuring the water content of the coconut fiber was 200 MHz–3 GHz, with an optimal frequency of 210 MHz. The dielectric measurement model for the water content in the coconut fiber established at this frequency demonstrated good applicability, with an R2 of 0.9704 and RMSE of 0.0453 cm3/cm3. At the same moisture level (θV of approximately 30% and 50%), the error in the real part of the dielectric permittivity was less than 1.35 between 15 and 35 °C, and the error in the moisture content was less than 0.0339 cm3/cm3. The error due to the salinity was 0.0750 cm3/cm3. The experimental results showed that the modeling of the water content measurement of coconut fiber at 210 MHz can be applied to general greenhouse environmental conditions. This study serves as a valuable reference for calibrating the moisture monitoring sensors used in greenhouses for coir cultivation substrates, emphasizing the need for non-destructive, real-time monitoring of moisture content.

The Mediterranean region is highly vulnerable to climate change, soil and water resource degradation, and biodiversity loss. These challenges disproportionately affect disadvantaged rural areas, impacting both natural resources and the livelihoods of local agricultural societies. Urgent transformative measures are essential to address land and water management as well as food security challenges in these disadvantaged areas. Living labs are being called upon to play a key role in addressing these challenges through the development of Nature-based Solutions (NbSs) that are able to provide environmental and socioeconomic benefits towards the achievement of Sustainable Development Goals. The aim of this work is to provide insights on an open innovation ecosystem of Mediterranean Living Labs for the synergetic development and participatory assessment of decentralized wetland-aquaponics, as NbSs are able to address environmental and food security challenges in disadvantaged rural areas. The study addresses the knowledge gap of Living Labs contribution to the development of decentralized wetland-aquaponics and the limited research on small-scale aquaponics systems in rural Mediterranean settings, while revealing the role of public participation in ascertaining the solution and evaluating its feasibility and impacts in light of the local social values and interests in the mountainous area of Akkar al-Atika in Lebanon.
Estimating Energy Efficiency and Energy Saving Potential in the Republic of Korea’s Offshore Fisheries
Authors: Jeon Yonghan , Nam Jongoh
Published: October 2023

The Republic of Korea’s government has established a carbon negativity policy to mitigate climate change in the fisheries sector. To achieve this objective, the government proposed enhancing energy efficiency in vessel fisheries, known for high carbon emissions. However, it was difficult to find research that investigated the energy consumption status of vessel fisheries. Thus, this study aims to calculate the offshore fisheries’ energy efficiency (EE) and to estimate the energy saving potential (ESP) needed in order to achieve efficient energy consumption. For this purpose, annual fisheries management surveys and data on the tax-free petroleum supply are employed. This study measures the EE and the ESP of offshore fisheries by year and fishing gear by employing the stochastic frontier analysis (SFA), which considers exogenous determinants of energy inefficiency. The analysis results show a decline in the EE over time and an increasing trend in the ESP. Notably, the trawl and fleet fisheries tend to have lower energy efficiency. Furthermore, the trawl and fleet fisheries were identified as having the highest ESP. Therefore, to utilize energy efficiently and reduce energy consumption in offshore fisheries, this study suggests scaling down fleet fisheries, developing energy saving fishing nets and eco-friendly fishing vessels, expanding modernization projects for fishing vessels, and revising the related acts.
Logistics Efficiency Evaluation and Empirical Research under the New Retailing Model: The Way toward Sustainable Development
Authors: Jiang Tongtong , Wu Xiuguo , Yin Yunxiao
Published: October 2023

As an innovative retailing mode, “new retailing” is making the distinction between physical and virtual commerce obsolete, where offline stores attract customers and supply them with the opportunity of experiences, and online stores provide services for placing orders and transactions. However, many new retailing companies are beset by their logistics efficiency evaluations because evaluation indicators and methods differ significantly from those with traditional business patterns. In this way, considering the sustainable development principle, this study focuses on the approach of logistics efficiency evaluation and empirical analysis under the new retailing model, explores the main factors related to logistics efficiency improvement, and proposes corresponding measures to reinforce the core competence of companies. We first establish a novel logistics efficiency evaluation index system by word frequency and correlation analysis from a sustainable development view, including six first-level indicators and twenty-seven second-level indicators; then, the logistics efficiency evaluation framework is presented: the static evaluation is made using cross-efficiency DEA and IAHP entropy; the dynamic evaluation is performed using the Malmquist index. After that, a demonstrated analysis of logistics efficiency is conducted with 15 listed companies in China. Furthermore, efficiency-influencing factors are identified using Tobit regression, and countermeasures are proposed to promote the development of new retailing. Comparison results show that the proposed logistics efficiency evaluation framework can be scientific and reliable, helping managers to identify the weaknesses and influencing factors in enterprise logistics operations, therefore improving the performance and competitiveness of new retailing companies.
The Risk of Household Socioeconomic Deprivation Related to Older Long-Term Care Needs: A Qualitative Exploratory Study in Italy and Spain
Authors: Casanova Georgia , Fernández-Salido Mirian , Moreno-Castro Carolina
Published: October 2023

Background: Older individuals with long-term care (LTC) needs represent a risk factor for poverty and socioeconomic deprivation (SED) for households. This challenge threatens the overall sustainability of health and social care systems. Spain and Italy have a robust family-based care regime with a high level of informal long-term care. Aims: This qualitative study aims to provide empirical evidence of the socioeconomic risks for Spanish and Italian households related to long-term care needs by identifying the phenomenon’s main characteristics and suggestions for innovative policies and solutions. In particular, this qualitative study examines the opinions of experts and stakeholders from both countries to: (a) explore the relationship between LTC needs and household SED risk in Spain and Italy; (b) identify key associations between words and concepts, highlighting their specific characteristics in both countries; and (c) perform an in-depth analysis of the interviewees’ views on designing innovative policies to support households, aimed at coping with the SED risk arising from the challenges posed by meeting the LTC needs of older people and their relatives Methods: National experts and stakeholders were involved in interviews and focus groups in both countries. A linguistic and content analysis of the transcriptions produced was performed and supported by T-LAB. Results: The SED risk for households was confirmed in both countries. Informal carers, often women, contend with a higher risk of material and social deprivation. To improve the coordination and integration strategy of public LTC, policies should contrast the SED risk of households. Moreover, an innovative integrated welfare model should consider valorizing different existing resources (e.g., informal care, neighbors, and NGOs). Conclusions: Long-term care policies aimed at promoting ageing need to pay more attention to such a risk as a structural component to be addressed and tackled with more specific and effective strategies.

Published: October 2023

Individuals and digital organizations deal with a substantial amount of collected data required for performing various data management strategies, such as replacing, upgrading, and migrating existing data from one system to another, while supporting the data’s complexity, authenticity, quality, and precision. Failures in data migration can result in data and service interruptions, financial losses, and reputational harm. This research aims to identify the specific challenges of a data management strategy, develop a comprehensive framework of data migration practices, and assess the efficacy of data validation and high availability for optimizing complex data and reducing the need to minimize errors during data migration. Combining trickle and zero-downtime migration techniques with a layering approach, a hybrid-layering framework was designed to encompass the entire spectrum of data migration techniques, beginning with system requirements and data transformation, rigorous functions, and evaluation metrics for sustainable data validation. The evaluation metric criteria are defined to evaluate data migration based on data consistency, integrity, quality, accuracy, and recall. The experiment demonstrated a real-world scenario involving a logistics company with 222 tables and 4.65 GB of data. The research compared various data migration strategies. The outcomes of the hybrid-layering framework’s examination of the final system’s functionality are satisfactory, emphasizing the critical importance of data migration sustainability to ensure data validity and high availability. This study is useful for individuals and organizations seeking to sustainably improve their data management strategies to minimize disruptions while preserving data integrity.

Published: October 2023

Singular singularly-perturbed problems (SSPPs) are a powerful mathematical tool for modelling a variety of real phenomena, such as nuclear reactions, heat explosions, mechanics, and hydrodynamics. In this paper, the numerical solutions to fourth-order singular singularly-perturbed boundary and initial value problems are presented using a novel quintic B-spline (QBS) approximation approach. This method uses a quasi-linearization approach to solve SSPNL initial/boundary value problems. And the non-linear problems are transformed into a sequence of linear problems by applying the quasi-linearization approach. The QBS functions produce more accurate results when compared to other existing approaches because of their local support, symmetry, and partition of unity features. This method can be applied to immediately solve the SSPPs without reducing the order in which they are presented. It has been demonstrated that the suggested numerical approach converges uniformly over the whole domain. The proposed approach is implemented on a few problems to validate the scheme. The computational results are compared, and they illustrate that the proposed approach performs better.
A Novel Hybrid MSA-CSA Algorithm for Cloud Computing Task Scheduling Problems
Authors: Alsubai Shtwai , Garg Harish , Alqahtani Abdullah
Published: October 2023

Recently, the dynamic distribution of resources and task scheduling has played a critical role in cloud computing to achieve maximum storage and performance. The allocation of computational tasks in the cloud is a complicated process that can be affected by some factors, such as available network bandwidth, makespan, and cost considerations. However, these allocations are always non-symmetric. Therefore, it is crucial to optimize available bandwidth for efficient cloud computing task scheduling. In this research, a novel swarm-based task scheduling with a security approach is proposed to optimize the distribution of tasks using available resources and encode cloud information during task scheduling. It can combine the Moth Swarm Algorithm (MSA) with the Chameleon Swarm Algorithm (CSA) for the task scheduling process and utilizes the Polymorphic Advanced Encryption Standard (P-AES) for information security of cloud scheduled tasks. The approach offers a new perspective for utilizing swarm intelligence algorithms to optimize cloud task scheduling. The integration of MSA and CSA with P-AES enables the approach to provide efficient and secure task scheduling by exploiting the strengths of used algorithms. The study evaluates the performance of the proposed approach in terms of the degree of imbalance, makespan, resource utilization, cost, average waiting time, response time, throughput, latency, execution time, speed, and bandwidth utilization. The simulation is carried out using a wide range of tasks from 1000 to 5000. The results show that the approach provides an innovative solution to the challenges of task scheduling in cloud environments and improves the performance of cloud services in terms of effectiveness and security measures.
A Narrative Literature Review of the Established Safety of Human Serum Albumin Use as a Stabilizer in Aesthetic Botulinum Toxin Formulations Compared to Alternatives
Authors: Sattler Sonja , Gollomp Stephen , Curry Andrew
Published: October 2023

Despite more than 80 years of use in a number of conditions, including in critically ill patients, comments have recently arisen regarding the safety and efficacy of human serum albumin (HSA) as a therapeutic product and stabilizer/excipient in botulinum neurotoxins. This review summarizes the literature on the safety of HSA. Beyond decades of safe use, the largest clinical dataset of HSA safety is a large meta-analysis of HSA supplier data, which found only an extremely remote risk of serious adverse events across millions of doses of therapeutic concentrations of HSA. There is a paucity of literature identifying HSA-specific adverse events when used as a stabilizer/excipient; however, studies of HSA-containing botulinum neurotoxins (BoNTs) suggest that adverse events are not related to HSA. Polysorbates, which are synthetically produced and not physiologically inert, are contained in pending or new-to-market BoNT formulations. In contrast to HSA, evidence exists to suggest that polysorbates (particularly PS20/PS80) can cause serious adverse events (e.g., hypersensitivity, anaphylaxis, and immunogenicity).

The rise in international travel has led to an increase in travel-related infectious diseases. It is predicted that by 2030, the number of international travelers will reach 1.8 billion, with over 250 million people affected globally. This issue also has an economic impact, as the eradication of travel-related infectious diseases leads to a loss of USD 12 billion in tourism. To understand the association between demographic variables and knowledge, attitude, and behaviors related to travel-related infectious diseases, a cross-sectional survey-based study was conducted among 1191 individuals in the metropolitan city of Naples, Italy. Multiple linear regression was performed over three models. The results revealed that knowledge about travel-related infectious diseases was positively associated with age, female gender, non-smoking habits, being single, and higher education attainment. The attitude towards travel-related infectious diseases was positively associated with being female, non-smoking habits, being single, higher education attainment, and a higher level of knowledge. A statistically significant association was observed between behaviors and non-smoking habits and between higher levels of knowledge and attitudes. To address this issue, public health programs could be implemented to improve behaviors in the general population. Overall, this study provides valuable information about the determinants of knowledge, attitude, and behaviors related to travel-related infectious diseases in the general population.
Detection of a Novel Alphaherpesvirus and Avihepadnavirus in a Plantar Papilloma from a Rainbow Lorikeet (Trichoglosis moluccanus)
Authors: Sarker Subir , Phalen David N.
Published: October 2023

Cutaneous plantar papillomas are a relatively common lesion of wild psittacine birds in Australia. Next-generation sequencing technology was used to investigate the potential aetiologic agent(s) for a plantar cutaneous papilloma in a wild rainbow lorikeet (Trichoglosis moluccanus). In the DNA from this lesion, two novel viral sequences were detected. The first was the partial sequence of a herpesvirus with the proposed name, psittacid alphaherpesvirus 6, from the Mardivirus genus of the family alphaherpesviruses. This represents the first mardivirus to be detected in a psittacine bird, the first mardivirus to be detected in a wild bird in Australia, and the second mardivirus to be found in a biopsy of an avian cutaneous papilloma. The second virus sequence was a complete sequence of a hepadnavirus, proposed as parrot hepatitis B genotype H (PHBV-H). PHBV-H is the first hepadnavirus to be detected in a wild psittacine bird in Australia. Whether other similar viruses are circulating in wild birds in Australia and whether either of these viruses play a role in the development of the plantar papilloma will require testing of biopsies from similar lesions and normal skin from other wild psittacine birds.

Published: October 2023

Viruses that are transmitted by arthropods, or arboviruses, have evolved to successfully navigate both the invertebrate and vertebrate hosts, including their immune systems. Biting midges transmit several arboviruses including vesicular stomatitis virus (VSV). To study the interaction between VSV and midges, we characterized the transcriptomic responses of VSV-infected and mock-infected Culicoides sonorensis cells at 1, 8, 24, and 96 h post inoculation (HPI). The transcriptomic response of VSV-infected cells at 1 HPI was significant, but by 8 HPI there were no detectable differences between the transcriptome profiles of VSV-infected and mock-infected cells. Several genes involved in immunity were upregulated (ATG2B and TRAF4) or downregulated (SMAD6 and TOLL7) in VSV-treated cells at 1 HPI. These results indicate that VSV infection in midge cells produces an early immune response that quickly wanes, giving insight into in vivo C. sonorensis VSV tolerance that may underlie their permissiveness as vectors for this virus.

Published: October 2023

The impact of pregnancy on human papillomavirus (HPV) natural antibody levels is not fully understood. We tested the seroprevalence and levels of HPV 6, 11, 16, 18 and 45 antibodies at different time points among 89 women with a second pregnancy and 238 nonpregnant women during their 36-month followup. All participants were unvaccinated for HPV and pregnant at the enrollment of the study. Serum samples were collected from the mothers at baseline and at the 12-month, 24-month, and 36-month followup visits. No statistically significant differences in mean antibody levels were observed in women who developed a second pregnancy compared to their nonpregnant counterparts. Between these two groups, statistically significant differences in serostatus were observed, particularly if the second pregnancy was ongoing at the 24-month timepoint. Accordingly, women with a second pregnancy were more likely to be seronegative for HPV 6, 11, 18, and 45 as compared to the nonpregnant women, the reverse being true for HPV16. In contrast, the women with an ongoing second pregnancy showed a higher prevalence of HPV16 seropositivity at the 36-month followup. These data suggest that a second pregnancy does not seem to have a major impact on the levels of HPV antibodies, but it might influence the serological outcomes.

Published: October 2023

This paper assesses the performance of waste heat recovery from commercial kitchen wastewater in practice. A pilot study of heat recovery from the kitchen at Penrhyn Castle, a tourist attraction in North Wales (UK), is outlined. The pilot heat recovery site was designed and installed, comprising a heat exchanger, recirculation pumps, buffer tank and an extensive temperature/flow monitoring system for performance monitoring of the waste heat recovery system. Continuous monitoring was conducted for a period of 8 months, covering the 2022 tourist season. The recovered heat from the kitchen wastewater preheats the incoming cold freshwater supply and consequently reduces the amount of energy consumed for subsequent water heating. Retrofitting the pilot heat recovery system to the kitchen drains resulted in a heat saving of 240 kWh per month on average, a reduction of 928.8 kg CO2e per year, and a payback period for the investment costs of approximately two years, depending on the cost of energy supply. The presented results illustrate the potential of this form of renewable heat in reducing the carbon footprint of water heating activities in buildings and the hospitality sector.
Research on Threshold Selection Method in Wave Extreme Value Analysis
Authors: Liu Huashuai , Yang Fan , Wang Hongchuan
Published: October 2023

Climate change poses higher requirements on ocean engineering design, and reasonable estimation of design wave heights plays a crucial role in coastal protection and offshore engineering. Extreme value analysis is widely used in frequency calculations of wave parameters, among which the peak over threshold method based on the generalized Pareto distribution is proven to be an effective method, and the different selection of extreme wave samples in this method has a great influence on the calculation results. In this study, long-term significant wave height series were utilized to investigate the long-range correlation of significant wave heights, and thresholds were determined based on the changes of long-range correlations. This approach assumes that extreme events and non-extreme events are generally caused by different physical processes, where extreme events result from massive disturbances leading to abnormal states, and long-range correlations are not affected or minimally affected by extreme events. Thus, thresholds can be determined based on changes of long-range correlations by removing extreme events. Comparing this method to graphical diagnostic techniques, we demonstrated its rationality in determining extreme wave height thresholds. Moreover, the automatic threshold selection offered by this method helps to mitigate errors associated with subjective judgments in traditional approaches.
Clustering Daily Extreme Precipitation Patterns in China
Authors: Huang Hefei , Cui Huijuan , Singh Vijay P.
Published: October 2023

Different regions exhibit significant differences in the characteristics of extreme precipitation, and the differentiation of such characteristics is not reported for all regions. To distinguish the characteristics of extreme precipitation in different regions in China, we extracted the distribution characteristics of extreme precipitation from daily precipitation data at 649 stations in China, 1961–2017, spatially grouped them by cluster analysis, and, finally, evaluated the effectiveness of zoning by a homogeneity test. Results showed that China can be divided into 33–35 extreme precipitation zones. Our map exhibits better homogeneity than the conventional climate map and other methods reported in the literature and better characterizes the regional distribution characteristics of extreme precipitation. It is noted that long–duration extreme precipitation has a more significant regional distribution consistency than short–duration extreme precipitation. Further, the western and northern regions of China are more prone to sudden, high–intensity extreme precipitation events, whereas the southeastern region is more vulnerable to frequent, high–intensity extreme precipitation events.

Published: October 2023

The study of aquifers of the Lece andesite complex (LAC) and its surroundings yielded a new procedural stepwise analysis that allowed the assessment of the origin of elements, particularly in areas affected by both anthropogenic and natural influences. The methodology uses the mineralogical composition of the rocks, including the elements available in rocks and groundwater. This study analyzes the element ratios B/Cl−, Na+/Ca2+, Ca2+/Mg2+, HCO3−/Cl−, and Na+/Na+ + Cl−; the correlations are coupled with a statistical analysis. In addition to reevaluating the already published water content, we provide an important new dataset. The results show that the main source of the water contamination with the elements B, F, U, As, Cu, Fe, Zn, Co, and Ni is the processes occurring at the contact between the groundwaters and non-altered/altered (propylitized) andesite rocks. This is also observed in the waters extracted from crystalline schists. The results may help develop an efficient use and assessment of the qualitative water potential of the LAC reservoirs. Similarly, the results highlight the applicability of the groundwaters, facilitating their regional research and use, further encouraging new initiatives for the preservation and protection of human and animal health.
Stability Analysis of a Transmission Line Tower and Slope under Heavy Rainfall

Published: October 2023

In recent years, our country’s transmission lines have often been in danger due to geological disasters such as landslides when passing through fragile geological environments, which has brought great challenges and risks to the operation and maintenance of transmission lines. In order to understand the impact of transmission line towers on tower foundation slopes under heavy rainfall conditions, the influence of towers at different locations, rainfall intensities, and slopes on slope stability was analyzed by using Geo-Studio finite element analysis software. The results show that the slope has an important influence on the selection of the reasonable position of the tower. When the tower is located at the lower part of the slope, the safety factor of the slope is the highest. The safety factor of the slope is also reduced, and eventually the slope will be unstable and destroyed; the stability coefficient of the slope in the natural state is 1.221, which is in a stable state. Slopes are prone to overall sliding, with the spoil and overburden as the sliding body and the rock–soil contact surface as the sliding surface. This result provides a scientific basis for further understanding the influence mechanism of the slope angle at the location of the tower pole on this type of landslide under rainfall conditions. Further research can use the results of this paper as a benchmark to carry out corresponding experimental analysis and verification work.

This study focuses on investigating and comparing the influence of the surface functional groups and chemical matrices of macroporous resin on the Cr(III) exchange mechanism. The results discussed herein indicate that sulfonic resin removed Cr(III) ions with faster kinetics than carboxylic resin. Equilibrium was established within 15 and 7 min for the carboxylic and sulfonic resins, respectively, with a 99.5% removal efficiency at 333 K. The Langmuir exchange capacity was observed to be higher for the sulfonic resin (1.5 mmol∙g−1) than the carboxylic resin (0.80 mmol∙g−1) at 333 K. The adsorption isotherms obtained for the carboxylic and sulfonic resins were H and S types, respectively, representing a higher affinity of the carboxylic resin for Cr(III) removal at a low metal ion concentration. Additionally, it was noted that the carboxylic resin preferentially co-sorbed H+ and Cr(OH)2+ ions below Cr(III) concentrations of 6–8 mmol.L−1. The H+ ions co-sorption was almost negligible, whereas the Cr(III) exchange was 87 and 34.5% for the carboxylic acid resin and sulfonic acid resins, respectively. The data of the concentration studies were evaluated using non-linear forms of Freundlich, Langmuir, and Dubinin–Radushkevich adsorption isotherm models, and the kinetic data were analyzed using pseudo-Ist- and pseudo-IIst-order kinetic models. The activation energy Ea for Amberlite IRC-50 (Na+) was greater (22.4 kJ∙mol−1) than that of Amberlyst-15 (Na+) 17 kJ∙mol−1, indicating a higher energy barrier for the ion exchange reaction on carboxylic resin. As per the findings of a statistical error analysis (RMSE and SSE) and absolute average relative distribution (AARD) statistical model, a close agreement between the experimental and theoretical values suggested that the Langmuir isotherm was well-fitted to the current adsorptive investigations. The interaction of the COO− and SO3− functional sites of the resins for the exchange of Cr(III) ions was validated through an FT-IR analysis. The macroporous resins used in the current study for Cr(III) exchange showed promising performances compared to other resins. The current investigations revealed valuable insights for choosing macroporous resins as adsorbents in water filtration systems.

Published: October 2023

Herbicides (weed control agents) are used in crops on a massive scale. MCPA (2-methyl-4-chlorophen- oxyacetic acid) is a herbicide used to control weeds in cereals and other crops. The aim of this study was to investigate the toxic effects of an MCPA-based herbicide formulation (Chwastox
Extra® 300 SL) in the common carp (Cyprinus carpio). The fish were exposed for 10 days, to a concentration which corresponded to 1 mg/l or 5 mg/l of MCPA. Our analysis showed fluctuations of the haematological parameters during the treatment. Plasma biochemical changes
that were statistically significant, i.e.a decrease of the total protein concentration and alanine aminotransferase activity, were observed after 1 day of exposure. No histopathological lesions in the gills, trunk kidney and liver were identified. The results of the present study indicate
that Chwastox Extra® 300 SL has a relatively low toxicity for the common carp. It was also observed that the blood indices were more sensitive to the tested herbicide formulation than the microstructure of the selected organs. Further research aimed at studying the effects of
Chwastox on water invertebrates and fish of other taxa is recommended.

Die sich rasch ändernden Rahmenbedingungen der modernen Arbeitswelt sorgen dafür, dass Spannungen innerhalb von Organisationen stetig zunehmen. Den Mitarbeitern wird in den Transformationsprozessen eine hohe Veränderungsbereitschaft abverlangt, die nicht selten zu einer Zunahme des individuell wahrgenommenen Stresses fuhrt, der in einer höheren Zahl sozialer Differenzen mündet, die sich zunehmend in Konflikten entlädt. Diese wachsende Zahl an Konflikten fordert die Führungskräfte. Die rechtzeitige Unterbrechung der Konfliktdynamik zahlt daher heutzutage zu den größten Führungsherausforderungen. Um Führungskräfte bei der Einordnung des Konfliktes und der Wahl der richtigen Strategie zur Konfliktbehandlung zu unterstutzen, hat Friedrich Glasl sein bekanntes Stufenmodell der Konflikteskalation entwickelt.

Geologic Map of the Southern Half of the Rill Creek and Northern Half of the Kane Springs 7.5' Quadrangles, Grand and San Juan Counties, Utah
Authors: Mauch James P. , Pederson Joel L.
Published: October 2023

The adjoining southern half of the Rill Creek and northern half of the Kane Springs 7.5′ quadrangles are southeast of Moab, Utah. This area includes the southeastern half of the Moab-Spanish Valley salt graben and the neighboring bedrock plateaus to the southwest and northeast. Mapping of this quadrangle-sized area is part of a broader effort to understand active salt deformation and the associated landscape evolution and geologic hazards in the ancestral Paradox Basin. Strata from Late Triassic to Late Cretaceous age are exposed in the map area, and Quaternary-age units include alluvial, colluvial, eolian, mass-wasting, and fluvial terrace deposits. Graben subsidence is accommodated by systems of shallowly seated, near-vertical, gravitational faults along the margins of Spanish Valley. The two graben-margin fault zones display contrasting deformation styles and fault geometries. Ongoing Quaternary subsidence in Spanish Valley is documented in the spatial and temporal distribution of terrace deposits along Mill and Pack Creeks, which confirms previous hypotheses of active salt deformation. The hazard of active, aseismic, salt-dissolution collapse and faulting appears to be modest, with greater concern relating to attendant mass-wasting processes along the valley margins.
Utah Mineral Occurrence System (UMOS) Database, 2023 Update
Authors:   Utah Geological Survey (Energy and Minerals Program)
Published: October 2023

The Utah Mineral Occurrence System (UMOS) is a database that includes known mineral mines, quarries, prospects, and deposits in Utah. The database focuses on metallic and industrial minerals, but also includes information on energy minerals (particularly uranium). The database includes extensive information for each record including location, related mineral commodities, geology, mineralogy, production data, resource size, important references, and other relevant information. Over recent decades, UMOS has been a useful tool for mineral explorers, mining companies, land managers, and the general public. We are releasing the current version of UMOS as an Open-File Report (OFR) in order to preserve versioning of the database. Over the years, UMOS or parts thereof have been released in UGS publications and a few of those references are cataloged below. We consider it worth noting that the current digital database consists solely of point data for each record, but many of the paper files and maps from the initial UMOS records provide additional information on the aerial extent of an occurrence or deposit. Some records also include substantial details or other reports that are not captured in the digital database. These paper files remain available at the UGS office in Salt Lake City.

Con 17.4 millones de toneladas, México es el principal importador de grano de maíz amarillo a nivel internacional (SIAP, 2022), su uso es para alimentos balanceados pecuarios, industria porcina, bovinos, ovinos, avicultura, huevo y otros rubros. El maíz es el grano de mayor relevancia en la alimentación para México, por su consumo per cápita de 346.4 kg por año, así como por el área de cultivo (7.3 millones de hectáreas), si bien el país es autosuficiente en producción de maíz blanco, ya que de 27.5 millones de toneladas, se destinan 13.5 millones para su consumo en tortillas (SIAP, 2022), la importación de maíz amarillo, así como los problemas internacionales para adquirir este grano, hacen urgente el incremento de producción y el fortalecimiento de este cultivo en la agricultura tradicional y de subsistencia, para ello se requieren variedades mejoradas de grano amarillo, con buena productividad para las áreas donde se siembra este tipo de variedades (Espinosa-Calderón et al., 2021b; Tadeo-Robledo et al., 2015). En la Mesa Central de México (2200 a 2600 msnm), en más del 50 % de las 1.5 millones de hectáreas, la humedad para el cultivo proviene de la precipitación pluvial, que con frecuencia llega retrasada, es insuficiente e irregular y obliga a sembrar con retraso, con afectación del cultivo por heladas tempranas, ya que las variedades empleadas de ciclo largo no logran su madurez y su rendimiento es escaso (1.2 t ha-1) (Espinosa-Calderón et al., 2021a).
As Escolas Mundiais IB em São Paulo, Lisboa e Maputo. Crescimento e diversificação do campo
Authors: Anne Schippling  , Abrantes Pedro
Published: October 2023

O artigo analisa o crescimento recente das escolas internacionais, centrando-se nos estabelecimentos de ensino que oferecem currículos e exames da International Baccalaureate® (IB), a partir de três eixos de pesquisa que se intersetam. Primeiro, procura-se mapear a investigação já produzida sobre este movimento, a nível internacional. Segundo, discute-se a evolução do número de escolas e de estudantes no mundo, com particular atenção às tendências observadas nos países lusófonos e ibero-americanos. Terceiro, apresentam-se resultados de uma análise documental sobre as escolas IB em São Paulo, Lisboa e Maputo, com enfoque nas suas missões e visões institucionais. Além de uma menor expressão, em comparação com o observado em países de língua espanhola, concluiu-se que o crescimento das escolas IB nas metrópoles de língua oficial portuguesa tem sido alimentado tanto pela conversão do modelo das escolas internacionais tradicionais, como pelo surgimento de projetos empresariais especializados neste tipo de escolas. A narrativa da excelência escolar e da formação de líderes globais tende a tornar-se hegemónica. Existem semelhanças, mas também variações entre as escolas IB destas três cidades, as quais relacionamos com os respetivos contextos.

DENEYİME AÇIKLIK VE İŞLE BÜTÜNLEŞME ARASINDAKİ İLİŞKİDE ÖZ-YETERLİĞİN VE MÜKEMMELİYETÇİLİĞİN ROLLERİ: DÜZENLEYİCİ ARACI MODEL

Published: October 2023

Mevcut araştırmanın temel amacı, deneyime açıklığın işle bütünleşme üzerindeki doğrudan ve dolaylı etkilerini (öz yeterlik aracılığıyla) mükemmeliyetçiliğin koşullu etkilerine göre düzenleyici-aracı model kapsamında incelemektir. Araştırmada nicel araştırma yöntemleri kullanılmıştır. Akademisyen ve öğretmenlerden oluşan 539 katılımcıya ilişkin veri, analizlerde kullanılmıştır. Araştırma hipotezlerini test etmek için Hayes Process Macro uzantısı (Model 58) kullanılmıştır. Araştırma sonuçlarında, deneyime açıklığın, öz-yeterliği ve işle bütünleşmeyi pozitif etkilediği; öz yeterliğin işle bütünleşmeyi pozitif etkilediği bulgulanmıştır. Deneyime açıklık ve öz-yeterlik arasındaki ilişkide mükemmeliyetçiliğin düzenleyici rolü olduğu görülmüştür. Düşük mükemmeliyetçilik koşulunda deneyime açıklığın öz-yeterliği pozitif etkilediği, yüksek mükemmeliyetçilik koşulunda deneyime açıklığın öz-yeterliği negatif etkilediği, orta mükemmeliyetçilik koşulunda deneyime açıklığın öz-yeterliği etkilemediği saptanmıştır. Benzer şekilde, öz-yeterlik ve işle bütünleşme arasında mükemmeliyetçiliğin düzenleyici rolü olduğu gözlemlenmiştir. Düşük ve orta mükemmeliyetçilik koşulunda öz-yeterliğin işle bütünleşmeyi pozitif etkilediği, yüksek mükemmeliyetçilik durumunda öz-yeterliğin işle bütünleşmeyi istatiksel olarak etkilemediği görülmüştür. Deneyime açıklığın işle bütünleşme üzerinde öz-yeterlik aracılığıyla dolaylı pozitif etkisinin sadece düşük düzeyde mükemmeliyetçilik koşulunda anlamlı olduğu tespit edilmiştir. Bu çalışmada, ikili zıtlıklar sadece düşük ve orta düzeyde mükemmeliyetçilik koşulunda anlamlı olduklarından, düşük ve orta düzeyde mükemmeliyetçi bireylerde, deneyime açıklığın öz-yeterlik aracılığıyla işle bütünleşme üzerindeki dolaylı etkilerin mükemmeliyetçilik seviyelerine göre koşullu olduğu; yüksek mükemmeliyetçilik düzeyine sahip bireylerde deneyime açıklığın öz-yeterlik aracılığıyla işle bütünleşme üzerindeki dolaylı etkisinin, mükemmeliyetçiliğe bağlı olmadığı ortaya konmuştur.
Traces of Anti-Technology (Ludist) Movement: Bibliometric Analysis
Authors: AYDIN Erdal
Published: October 2023

The concept of technological progress; It is used to describe the changing production processes with the effect of industrial revolutions, the effects of individuals on employment structures, and the changes and developments in this field. The increase in productivity with the inclusion of machines in the production processes, the savings in time and the idea that artificial intelligence can replace the human brain in the future have made the changes in employment processes and the effects of technological progress on this process controversial. The view that emerged as machine crushing and focused on the negative effects of technological progress on employment in the literature as a ludist movement suggests that machines in production will replace individuals over time and cause negative effects on human welfare. In addition, with the industrial revolutions and technological advances, the dimensions of the ludist movement have shifted to different points such as the use of artificial intelligence instead of the human brain, the disappearance of professions and the emergence of new professions, the development of skills and abilities. In this study, Ludism was considered as a concept that was the subject of research in different fields and it was aimed to contribute to the researchers in the context of the literature by analyzing it bibliometrically.
