Authors: Shreya Gupta
Published: October 2024

The purpose of this study is to report a link between the three disciplines of human resource accounting, accounting and finance and performance evaluation through a conceptual framework highlighting the interfaces between them. The term interface here refers to the points of interaction, connection or overlap between these three disciplines, highlighting how these disciplines interact, intersect or work together within the conceptual framework. The conceptual framework is designed based on a previous literature review. The final outcome of this study is a conceptual framework which reports the interface areas between human resource accounting and accounting and finance and between human resource accounting and performance evaluation, along with the individual roles of accounting and finance, human resource accounting, and performance evaluation disciplines in the interface development. This study contributes to the existing body of accounting literature by showing how accounting and finance lays down the foundation for the valuation and reporting of human resources in an organization, which in turn, facilitates in performance evaluation.

Authors: Martinez-Balderrama Raul , Rodriguez-Urrea Marcela Deyanira , García-Vázquez Juan Pablo , Mendoza-Muñoz Ismael , Jacobo-Galicia Gabriela
Published: October 2024

Purpose: To identify which psychosocial factors can be related to the increasing automation of work processes, determining practical implications relevant to the evaluation of psychosocial risk factors at work within organizations before the imminent transition towards industry 4.0
Design/methodology/approach: A systematic review of the literature was carried out. The review structure was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approach for the studies selection and the Noblit and Hare's meta-ethnographic approach for data analysis and synthesis.
Findings: Thirty-five studies were selected which passed all the selection stages. Six psychosocial risk factors were detected whose behaviors may be influenced by the increasing automation of work. Evidence suggests that the factors of development possibility, change management, mental load, routine content, and job insecurity may increase their exposure due to job modifications owing to new automation technologies. On the other hand, social relationships at work have the ability to positively influence the successful implementation of new automated processes.
Originality/value: The results obtained represent excellent indications of an overview of psychosocial risk factors that may increase their danger due to the increasing automation of work processes and Industry 4.0.

Published: October 2024

Cybersecurity is a critical aspect in the digital age,and one of the most recurrent challenges facing companies, especially large ones, is cyberattacks aimed at stealing valuable information. These attacks not only pose a threat to data integrity but can also cause significant economic damage and erode customer trust. In this research, the primary objective is to shed light on a particularly insidious form of cyberattacks targeting companies, an ostensibly weak yet critical link in thecybersecurity chain. Understanding this phenomenon isessential for preventing these attacks, as companies must recognize that through their personnel, they can lose critical information. This awareness is crucial for implementing effective measures to safeguard the company's digital assets.

The inclination to pursue fashion and beauty digital entrepreneurship amongst selected final year Diploma students in a South African university
Authors:   , Maphanga Ezile
Published: October 2024

In the age of digital transformation, the inclination to pursue digital entrepreneurship has become rampant, bringing about a broader acceptance of the idea of conducting business online especially by young people. In that regard, entrepreneurs are seizing the opportunity through digital entrepreneurship, with the fashion and beauty industry being a prominent sector for online business. Despite the growth in online fashion and beauty trading, there is limited research and understanding with the discourse surrounding it. The aim of the study was to examine the inclination to pursue fashion and beauty digital entrepreneurship amongst selected final year Diploma students in a South African university. The objectives of the study were: to establish the level of interest in pursuing digital entrepreneurship with regards to fashion and beauty amongst selected final year Diploma students, to determine factors that would influence the uptake of digital entrepreneurship with reference to fashion and beauty amongst selected final year Diploma students, and to assess using the Technology Acceptance Model (TAM) the inclination to pursue digital entrepreneurship in fashion and beauty amongst selected final year Diploma students. The study employed the Technology Acceptance Model to determine whether students intended to accept digital entrepreneurship. Methodologically, the study implemented the positivist research paradigm. The research approach chosen was quantitative. A survey research design was conducted through a questionnaire, as a data collection tool, from a census of the 29 final year students studying their Diploma in Fashion Design and 65 studying for their Diploma in Somatology. Instruments were pre-tested on 10 students, 5 in the Advanced Diploma in Fashion Design and 5 in the Advanced Diploma in Somatology at DUT. Findings showed a strong interest to pursue digital entrepreneurship in the fashion and beauty space. However, hesitations related to ‘customer satisfaction’ and ‘trust’ negatively influence the uptake of digital entrepreneurship. The findings also revealed that respondents were most likely to incorporate digital technologies in their businesses and saw the importance of administrative functions and advertising skills to have when venturing into digital entrepreneurship. The study recommends the youth to: be encouraged to consider entrepreneurship by South African universities; familiarize themselves with digital entrepreneurship and get education and knowledge in that regard; acquire the necessary skills in order to venture into digital entrepreneurship.

Published: October 2024

Abstract. The Benguela Upwelling System (BUS), located in the southeastern Atlantic Ocean, represents one of the world's most productive regions. This system is delimited to the south by the Agulhas retroflection region. The northern boundary of the BUS is, instead, represented by the Angola–Benguela Front (ABF), which is a thermal feature separating warm waters of the Angola Basin (including the South Atlantic Central Water; SACW) from the cooler Benguela Oceanic Current (BOC). We performed statistical analyses on planktonic foraminiferal assemblages in 94 samples from Holes U1575A and U1576A, cored during International Ocean Discovery Program (IODP) Expedition 391. Drilled sites are located along the Tristan–Gough–Walvis Ridge (TGW) seamount track in the northern sector of the BUS (offshore the Namibian continental margin). The analyzed stratigraphic intervals span the Early–Late Pleistocene, marked by the Early–Middle Pleistocene transition (EMPT; 1.40–0.40 Myr), during which important glacial–interglacial sea surface temperature (SST) variabilities occurred. This work provides novel insights on the local paleoceanographic evolution of the northern BUS and associated thermocline variability based on the ecological significance of the foraminiferal assemblages. Specifically, variations in the assemblage content allowed us to characterize the different water masses (BOC, SACW, and Agulhas waters) and reconstruct their interactions during the Quaternary. The interplay of the previously mentioned water masses induced perturbations in the BUS (ABF latitudinal shifts and input of tropical waters from the Agulhas retroflection region). Furthermore, we investigated the possible link between changes in the paleoceanographic conditions and climatic events (e.g., Benguela Niño-/Niña-like phases and deglaciation stages) recorded since the EMPT.

Abstract. Soot aerosol generated from the incomplete combustion of biomass and fossil fuels is a major light-absorber, however its spectral optical properties for varying black carbon (BC) and brown carbon (BrC) content remains uncertain. In this study, propane soot aerosols with varying size, maturity, and composition, i.e. elemental to total carbon ratio (EC/TC), have been studied systematically in a large simulation chamber to determine their mass absorption, scattering, and extinction cross sections (MAC, MSC, MEC), single scattering albedo (SSA), and Absorption and Scattering Ångström Exponents (AAE, SAE). Apart from the MSC, all other parameters show a variability associated with the soot EC/TC ratio in soot. The MAC at 550 nm increases for increasing EC/TC, with values of 1.0 m2g-1 for EC/TC=0.0 (BrC-dominated soot) and 4.6 m2g-1 for EC/TC=0.79 (BC-dominated soot). The AAE and SSA at 550 nm decrease from 3.79 and 0.29 (EC/TC=0.0) to 1.27 and 0.10 (EC/TC=0.79). A combination of our results for propane soot with literature data for laboratory flame soot from diverse fuels supports a generalized exponential relationship between particle EC/TC and its MAC and AAE values, representing the spectral absorption of soot with varying maturity to lie in an optical continuum. From this, we extrapolate a MAC of 7.9 and 1.3 m2g-1 (550 nm) and an AAE (375–870 nm) of 1.05 and 4.02 for pure EC (BC-like) and OC (BrC-like) propane soot. The established relationship can provide a useful parameterization for models to estimate the absorption from combustion aerosols and its BC and BrC contributions.
Drought propagation in high-latitude catchments: Insights from a 60-Year Analysis Using Standardized Indices

Published: October 2024

Abstract. Droughts, traditionally less associated with high-latitude regions, are emerging as significant challenges due to changing climatic conditions. Recent severe droughts in Europe have exposed the vulnerability of these northern catchments, where shifts in temperature and precipitation patterns may intensify drought impacts. This study investigates the dynamics of drought propagation in high-latitude regions, focusing on four key aspects: (1) the typical lag time for drought conditions to propagate from initial precipitation deficits to impacts on soil moisture, streamflow, and groundwater systems, (2) the probability of precipitation deficits leading to these droughts, (3) the key factors influencing drought propagation, and (4) how drought propagation has evolved under changing climate conditions. By analyzing long-term observational records from 50 Swedish catchments, the study reveals that drought propagation is highly variable and influenced by a complex interplay of catchment characteristics, hydroclimatic conditions, and soil properties. Soil moisture exhibits the shortest propagation times, often responding within a month to precipitation deficits, while groundwater shows the longest and most variable response times, sometimes exceeding several months. The probability of precipitation deficits propagating into soil moisture droughts is highest, followed by streamflow and groundwater, with these probabilities increasing over time. Across all drought types, annual precipitation and streamflow are the strongest governing factors, driving both propagation time and probability. Despite ongoing changing climate, drought propagation times or probabilities have not significantly changed over the past 60 years. However, while most catchments are becoming wetter across all seasons, southern catchments become more vulnerable to spring drought due to increased evaporative demand. These findings highlight the need for tailored, region-specific water management strategies to address seasonal and regional variations in drought risks, particularly as climate change continues to evolve.
Variation of the interspecific forest mass-density relationship along gradients of leaf area and global radiation
Authors: van Roestel Jan J. M.
Published: October 2024

Abstract. Stand mass scales as the -1/3 exponent of plant density for large compilations of plant communities on a continental or global scale, being the slope of the regression line in a log–log plot, where the intercept is a normalization constant reflecting the assumption of a constant rate of energy use by the species and environments involved. Here the normalization constant is replaced by a light absorption function, enabling to investigate how the interspecific mass–density relationship varies along spatial, largely latitudinal gradients of leaf area and the sum of global radiation over the growing season for relatively undisturbed forests. The test of the model for globally distributed forest communities shows the highest explained variance when both gradients are included in the light absorption function, meaning that the exponent is determined not only by the rate but also the sum of energy use over the growing season. The exponent of tree density converges to 1/2 instead of the expected 1/3 value based on the -1/3 exponent value in the bivariate biomass–density relationship. The 1/2 value corresponds with the so-called self-thinning rule that applies to the self-thinning line constructed as the upper boundary of mass–density points for monospecific even-aged plant stands, where gradients in energy use can be neglected. The results demonstrate the appropriateness of introducing a light absorption function in the bivariate mass–density relationship, suggesting a thermodynamic interpretation that may be of interest to other plants and even animals when gradients in energy use similarly affect the intercept and slope of the interspecific mass–density relationship.

Abstract. A substantial portion of tropospheric O3 dry deposition occurs after diffusion of O3 through plant stomata. Simulating stomatal uptake of O3 in 3D atmospheric chemistry models is important in the face of increasing drought induced declines in stomatal conductance and enhanced ambient O3. Here, we present a comparison of the stomatal component of O3 dry deposition (egs) from chemical transport models and estimates of egs from observed CO2, latent heat, and O3 flux. The dry deposition schemes were configured as single-point models forced with data collected at flux towers. We conducted sensitivity analyses to study the impact of model parameters that control stomatal moisture stress on modeled egs. Examining six sites around the northern hemisphere, we find that the seasonality of observed flux-based egs agrees with the seasonality of simulated egs at times during the growing season with disagreements occurring during the later part of the growing season at some sites. We find that modeled water stress effects are too strong in a temperate-boreal transition forest. Some single-point models overestimate summertime egs in a seasonally water-limited Mediterranean shrubland. At all sites examined, modeled egs was sensitive to parameters that control the vapor pressure deficit stress. At specific sites that experienced substantial declines in soil moisture, the simulation of egs was highly sensitive to parameters that control the soil moisture stress. The findings demonstrate the challenges in accurately representing the effects of moisture stress on the stomatal sink of O3 during observed increases in dryness due to ecosystem specific plant-resource interactions.
Phytoplankton responses to iron and macronutrient fluxes from subsurface waters in the western North Pacific in summer

Published: October 2024

Abstract. Iron (Fe) and macronutrient supplies and their ratios are major factors determining phytoplankton abundance and community composition in the North Pacific. Previous studies have indicated that Okhotsk Sea Intermediate Water and North Pacific Intermediate Water (NPIW) transport sedimentary Fe to the western subarctic Pacific. Although the supply of Fe and macronutrients from subsurface waters is critical for surface phytoplankton productivity, return paths from NPIW to the subsurface and their impact on the abundance and community composition of the organisms have not been fully understood. In this study, Fe and macronutrient turbulent fluxes, as well as the flux ratios from NPIW to surface waters, were calculated based on a chemical dataset, which included Fe and macronutrient concentrations, with turbulent mixing parameters obtained from the same cruise and same station along the 155° E transect in summer. Additionally, vertical flux divergence was calculated from the estimated vertical fluxes. Surface and subsurface phytoplankton community composition was evaluated in the CHEMTAX program based on algal pigment measurements. The results show that diatom abundance is significantly correlated with the vertical fluxes of Fe and macronutrients, especially with Fe and silicate (Si) fluxes, and with the Fe/N flux ratio along the section line. These results suggest that diatom abundance was controlled by Fe supply from subsurface waters in summer. The computed turbulent flux divergence in the subarctic and Kuroshio-Oyashio Transition Area suggests that enhanced concentrations of Fe and Si in the subsurface layer were supplied from NPIW.
RASCAL v1.0: an open-source tool for climatological time series reconstruction and extension
Authors: González-Cervera Álvaro , Durán Luis
Published: October 2024

Abstract. The reduction of in situ observations over the last few decades poses a potential risk of losing important information in regions where local effects dominate the climatology. Reanalyses face challenges in representing climatologies with highly localized effects, especially in regions with complex orography. Empirical downscaling methods offer a cost-effective and easier-to-implement alternative to dynamic downscaling methods and can partially overcome the aforementioned limitations of reanalyses by taking into account the local effects through statistical relationships. This article introduces RASCAL (Reconstruction by AnalogS of ClimatologicAL time series), an open-source Python tool designed to extend time series and fill gaps in observational climate data, especially in regions with limited long-term data and significant local effects, such as mountainous areas. Employing an object-oriented programming style, RASCAL's methodology effectively links large-scale circulation patterns with local atmospheric features using the analog method in combination with principal component analysis (PCA). The package contains routines for preprocessing observations and reanalysis data, generating reconstructions using various methods, and evaluating the reconstruction's performance in reproducing the time series of observations, statistical properties, and relevant climatic indices. Its high modularity and flexibility allow fast and reproducible downscaling. The evaluations carried out in central Spain, in mountainous and urbanized areas, demonstrate that RASCAL performs better than the ERA20C and ERA20CM reanalysis, as expected, in terms of R2, standard deviation, and bias. When analyzing reconstructions against observations, RASCAL generates series with statistical properties, such as seasonality and daily distributions, that closely resemble observations. This confirms the potential of this method for conducting robust climate research. The adaptability of RASCAL to diverse scientific objectives is also highlighted. However, as with any other method based on empirical training, this method requires the availability of sufficiently long-term data series. Furthermore, it is susceptible to disruption caused by changes in land use or urbanization processes that might compromise the homogeneity of the training data. Despite these limitations, RASCAL's positive outcomes offer opportunities for comprehensive climate variability analyses and potential applications in downscaling short-term forecasts, seasonal predictions, and climate change scenarios. The Python code and the Jupyter Notebook for the reconstruction validation are publicly available as an open project.

Published: October 2024

This study designs and builds a PLC application to optimize the dynamic braking process of a three-phase induction motor for safer and more efficient operation. This application monitors the motor braking system and calculates the motor braking time through a computer. The method used is experimental with the aim of designing a PLC application as a motor braking system using the dynamic braking method. The braking system utilizes PLC as the control system. To achieve dynamic braking, the stator coil of the motor receives an injection of direct current (DC) from a directed power source. In this testing, the observed variables are the injected DC current value and the duration of the injection time. The test results demonstrate that the implementation of PLC in the dynamic braking of a three-phase induction motor performs well in calculating the motor braking time and monitoring the braking process. With a DC current injection of 0,5 A in the dynamic braking test, an average stopping time of 2,63 seconds was obtained. With a DC current injection of 0,75 A in the dynamic braking test, an average stopping time of 2,13 seconds was obtained. .
Stability Analysis Of Two-Position Control System In Interacting Tanks Using Describing Function Method
Authors: Andi Purwandito Tulus Asmoro
Published: October 2024

In a water storage unit consisting of 3 interacting tanks, in its operation there will be problems if manual control is used, because if manual control is not optimal, then when filling water in the three tanks it will cause water overflow, which results in a lot of water being wasted. Two-position control, or "on-off," is a control system that is suitable for use in regulating the water level in the storage unit tank. In a two-position control system, if the frequency of water up and down (Limit Cycle) is large, it will cause an increase in the number of "switching" and "on-off" operations of the switch and solenoid valve per minute, so that the system becomes unstable and will shorten the life of the component. The Describing Function (DF) method is an analysis method that can determine the Limit Cycle frequency based on the width of the water up and down range (hysteresis) of the two-position control system, with the aim of determining the hysteresis parameters that cause the system to be stable.

Capacity building can be done in two ways, namely through hard skills (work skills) and soft skills (personal and behavioral skills). Soft skills is a sociological term that refers to personality characteristics, social attractiveness, negotiation skills, personal habits, caring, and optimism. Soft Skills are personality and behavioral abilities and skills. These soft skills complement hard skills as technical requirements for a job. The objectives of the service activities that will be carried out include (a) providing understanding to village officials about the capacity building needed in community service and (b) providing skills in community service in the form of personal skills and behavior so as to improve the quality of community service. Village officials and other community servants have not been able to provide maximum services due to lack of discipline and responsibility, lack of cooperation both among officers and with the community. Village officials and other community servants such as posyandu officers, members of village PKK mobilizers, are officers who provide services to the community. Village officials and other community servants have not been able to provide maximum services due to lack of discipline and responsibility, lack of cooperation both among officers and with the community. This phenomenon is an indicator of a lack of ability or capacity as a public servant. Their main tasks and functions related to village government are quite well understood, but the supporting factors for their tasks which are directly related to their personal capacity as servants are still lacking. Capacity building through outbound activities is an outdoor activity which is training in the form of games to build personal abilities and behavior in improving the quality of service to the community. Capacity building activities can build aspects of personality and behavior of village officials as soft skills which are an inseparable part of basic skills in the form of basic tasks (hard skills) and functions as village government officials.
