Business students’ intentions to apply to business-to-business sales jobs: A case study

Abstract As modern business-to-business (B2B) sales have become more complex; recruiters are turning to business schools to find educated and motivated sales professionals to fill the employment demand gap that has risen. This study provides important information about business students’ intentions regarding pursuing careers in B2B sales, as there are no up-to-date studies investigating the phenomenon. The purpose of this study is to investigate how business students’ attitudes and perceptions of personal sales competence affect their intentions to apply to B2B sales positions. The empirical data for the present study was collected by an online survey from business school students (n = 243). The conceptual framework was constructed by integrating the theory of reasoned action (TRA) and self-determination theory (SDT) and therefore this study contributes to aforementioned research. The results from structural equation modelling (SEM) indicate that the students were not eager to apply for B2B sales jobs. However, students’ attitudes positively influenced their intentions to apply for B2B sales jobs. The students’ intentions to apply for B2B sales jobs were also positively influenced by their perceptions of personal sales competence. The results of the study show that the industry and the business educators still have work to do to increase the appeal of professional sales jobs to attract business students to work in B2B sales jobs. Furthermore, the results inform companies’ human resource management to enhance B2B sales force recruitment.
Design and Analysis of Printed Lossy Capacitive Surface-Based Ultrawideband Low-Profile Absorber

In this communication, an ultrawideband low-profile absorber is designed using printed lossy capacitive surface on a ground-backed substrate. Simple guidelines are proposed to design the absorber using the impedance analysis of its equivalent circuit model. The 10 dB reflection reduction for 120% fractional bandwidth from 3 to 12 GHz is achieved by generating three resonances using a single element in the unit cell. The thickness at the lowest cutoff frequency of the proposed absorber is thus obtained as $0.080\lambda _{L} (\lambda _{L} $ is the wavelength at the lowest cutoff frequency). It is shown that the proposed absorber is polarization insensitive and capable of reducing radar cross section for all the reflection angles in both monostatic and bistatic scenarios. To manufacture the absorber, commercially available low-cost resistive ink, Y-shield HSF 74 is used. The measurement results are provided to validate both the full-wave and circuit simulated results.
Assessment of Vibrio populations in a transect of Rhizophora mangle in Punta Galeta, Panamá: culture-dependent analyses reveal biotechnological applications

Introduction: Rhizophora mangle is considered a niche for microorganisms with potentially novel and complex degrading enzymes. Objective: To characterize Vibrio populations using culture-dependent methods, from samples collected from sediments and water along a red mangrove transect composed of three sites. Methods: Strains were characterized according to their distribution, diversity, degradation of organic matter, and environmental parameters. Results: Bacterial densities were strongly associated with temperature and salinity. A total of 87 good-quality sequences representing the isolates from the three sites, were binned into eight OTUs (Operational taxonomic units). Taxonomic assignment indicated that the dominant members were Vibrionaceae. Beta diversity analyses showed that bacterial communities clustered by sample source rather than spatial distribution, and that alpha diversity was found to be higher in water than in sediment. Three percent of the strains from water samples could degrade carboxyl-methyl cellulose with the smallest enzymatic indexes compared to 4 % of the strains from sediment samples that showed the highest enzymatic indexes. Two strains identified as Vibrio agarivorans degraded cellulose and agarose, producing the highest enzymatic indexes. Conclusions: We found higher bacterial densities and diversity in the bacterial communities of the water samples compared to the sediment, with different OTUs including those similar to Ferrimonas, Providencia, or Shewanella which were not isolated in the sediment. Vibrio OTUs were shown to degrade cellulose in both sample types. The results of this study highlight the importance of red mangroves as Vibrio habitats and as reservoirs of potential enzyme sources with biotechnological applications.
Health factors associated with cognitive frailty in older adults living in the community

Introduction This study aims to investigate the health factors associated with cognitive frailty in frail and pre-frail older adults living in the community. Methods A total of 233 older adults meeting Fried’s criteria for pre-frailty or frailty were included. Cognitive status was evaluated using the Short Portable Mental Status Questionnaire. Health factors encompassed nutritional status (evaluated using the Mini Nutritional Assessment tool, body mass index, and waist, arm, and leg circumferences), physical function (assessed with the Short Physical Performance Battery), quality of life (measured with the total index of the EuroQoL 5-Dimension 5-Level questionnaire - EQoL-Index -, and the Visual-Analogue Scale - QoL-VAS - for today’s health state), as well as sleep, physical activity, and inactivity estimated through wrist-worn accelerometers. Multivariable logistic regression analyses were conducted to identify potential predictors of cognitive frailty, considering age as a confounding factor. Results Cognitive frail participants exhibited advanced age, heightened self-reported exhaustion, diminished overall physical performance, reduced leg perimeter, decreased engagement in moderate-to-vigorous physical activity, and higher levels of inactivity (all p<0.05). However, after adjusting for age, only QoL-VAS emerged as a cognitive frailty risk factor (Odds ratio: 1.024), while the EQoL-Index, calf perimeter, and levels of moderate-to-vigorous physical activity were identified as protective factors (Odds ratios: 0.025, 0.929, and 0.973, respectively). Discussion This study highlights the complex relationship between non-modifiable factors such as age, and modifiable factors including quality of life, nutritional status, and physical activity in the development of cognitive frailty among older adults with a frailty phenotype living in the community.
Novel Non-Centrosymmetric NdSr4O(BO3)3 Borate and Nd(Ca1−xSrx)4O(BO3)3 Solid Solutions: Preparation, Crystal Structures, Thermal Expansion and Optical Properties

A novel non-centrosymmetric NdSr4O(BO3)3 borate and solid solutions of Nd(Ca1−xSrx)4O(BO3)3 (x = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.7, 1.0) were synthesized by solid-state reactions as well as crystallization from a melt. The crystal structures of the Nd(Ca1−xSrx)4O(BO3)3 solid solutions with x = 0.2, 0.5 and 1.0 were determined from single crystal X-ray diffraction data and refined in the monoclinic space group Cm to Robs = 0.028, 0.034 and 0.028, respectively. The thermal expansion of the samples with x = 0, 0.2 and 0.5 was investigated using powder high-temperature X-ray diffraction in the temperature range of 25–1000 °C. A similarity of the thermal and compositional (Ca-Sr substitution) deformations of Nd(Ca1−xSrx)4O(BO3)3 solid solutions is revealed: Heating of Nd(Ca0.5Sr0.5)4O(BO3)3 by 1 °C leads to the same deformations of the crystal structure as increasing the amount of Sr atoms in Nd(Ca0.5Sr0.5)4O(BO3)3 by 0.26 at% Sr. The SHG signal of the series of Nd(Ca1−xSrx)4O(BO3)3 solid solutions has a maximum at approximately x = 0.2.
Does service sector growth influence tax revenue in Tanzania?

Abstract The study of the influence of service sector expansion on tax revenue is critical, but it has received little attention. The majority of the studies focused on how the service sector affects economic growth. This study aims to investigate how Tanzania’s expanding service sector affects tax revenue. This study used autoregressive distributed lag (ARDL) bounds testing to examine the influence of service sector growth on tax revenue in Tanzania for the period 1970–2018. Results show that service sector growth has a positive influence on tax revenue. Specifically, the government service sector and the trade service sector are confirmed to have a positive and significant influence on tax revenue in Tanzania. The business service sector, the transport service sector, and the personal service sector show insignificant results. This study contributes to the service sector and tax revenue literature by providing evidence showing that service sector growth can influence tax revenue. This paper presents a straightforward tax revenue collection model within the service sector, which holds significant implications for tax authorities, government entities, and policymakers. These findings suggest that improving tax policy can be achieved by targeting specific service subsectors.
THE UTILIZATION OF DUOLINGO TO BOOST STUDENTS’ GRAMMAR MASTERY IN SENIOR HIGH SCHOOL

This classroom action research utilized Duolingo to enhance the grammar mastery of 31 senior high school students in Reported Speech. The research procedures cover; planning, acting, observing, and reflecting. The researchers collected data through tests. The results demonstrated a significant improvement in students' grammar of Reported Speech mastery, with test average scores increasing from 56.77 to 85.16. Regarding the result, teachers are suggested to integrate technology-based learning tools like Duolingo to create engaging and interactive learning environments and enhance students‘ mastery. However, it is important to note that individual student progress varied, and some students showed more substantial improvements compared to others. Further analysis and consideration of factors such as individual learning styles, frequency of Duolingo usage, and additional instructional support may help understand the variations in student performance.
Cardiac Dose Predicts the Response to Concurrent Chemoradiotherapy in Esophageal Squamous Cell Carcinoma

Simple Summary Pursuing a maximal clinical response for esophageal cancer after definitive chemoradiation is crucial, as it may be an integral surrogate endpoint for survival. In addition, radiation dosimetry parameters and treatment-induced inflammation have been validated in terms of survival outcomes. This study evaluated the treatment response and clinical variables to determine whether there were correlations between them. In non-surgical candidates, the optimization of radiation techniques to spare cardiac irradiation should be emphasized. Abstract Definitive concurrent chemoradiation (CCRT) is the standard treatment for cervical esophageal cancer and non-surgical candidates. Initial treatment response affects survival; however, few validated markers are available for prediction. This study evaluated the clinical variables and chemoradiation parameters associated with treatment response. Between May 2010 and April 2016, 86 completed CCRT patients’ clinical, dosimetric, and laboratory data at baseline and during treatment were collected. Cox regression analysis assessed the risk factors for overall survival (OS). A receiver operating characteristic curve with Youden’s index was chosen to obtain the optimal cut-off value of each parameter. Treatment response was defined per Response Evaluation Criteria in Solid Tumors v.1. 1 at the first post-CCRT computed tomography scan. Responders had complete and partial responses; non-responders had stable and progressive diseases. Logistic regression (LR) was used to evaluate the variables associated with responders. The Cox regression model confirmed the presence of responders (n = 50) vs. non-responders (n = 36) with a significant difference in OS. In multivariate LR, cardiac dose–volume received ≥10 Gy; the baseline hemoglobin level, highest neutrophil to lymphocyte ratio during CCRT, and cumulative cisplatin dose were significantly associated with the responders. The initial clinical treatment response significantly determines disease outcome. Cardiac irradiation may affect the treatment response.
Simulation Study of the Effect of Microscopic Disturbances on the Propagation of Initial Streamer and Branching Characteristics in Transformer Oil

The governing equations of charged carriers were formulated using COMSOL simulation software. Various ionization sources, including field ionization, impact ionization, ion dissociation, and microscopic disturbance ionization charges, were employed to perform numerical simulations on a 2-D model of a needle-plate electrode submerged in transformer oil. This investigation analyzed the distribution of charge generation rates under different ionization mechanisms and explored the effects of varying microscopic disturbance source positions, radii, and charge generation rates on streamer propagation. The study also examined the branch shape and characteristics of the streamer under different voltage peaks and disturbance source distributions. The results highlight the predominant role of the field ionization mechanism as the primary ionization source for streamer discharge in transformer oil. Regarding disturbance source properties, larger disturbance source radii exerted a more significant effect on the streamer, whereas distances exceeding 0.1 mm from the axis center and lower charge generation rates (below ${2} {}\times {}{10} ^{{9}}$ A/ $\text{m}^{{3}}$ ) resulted in a reduced effect on streamer behavior. Furthermore, the research explored the effect of multiple stochastic disturbance sources on streamer propagation, revealing a close correlation between the shape of streamer branches and the distribution of disturbance sources within the discharge region. Higher voltage peaks were associated with extended streamer propagation distances and an increased number of streamer branches within the same rise time. This study provides a reference for advancing the propagation of partial discharge in liquid dielectric and the study of its branch formation mechanism.
Landowner Attitudes and Perceptions of Impact from Wind and Natural Gas Development in Northern Pennsylvania: Implications for Energy Landscapes in Rural America

The United States has undergone a recent boom in the development of onshore wind farm and natural gas energy projects and contentious debates over the construction of these projects are common in communities across the United States. A survey of landowners in a region of Northern Pennsylvania (N = 1028) undergoing simultaneous development of both wind and natural gas development shows that landowners are generally much more polarized and negative towards gas development than wind farm development, and that attitudes toward natural gas development is highly dependent on environmental attitudes and industry leasing, development, or employment experience. Landowner proximity to the development explains a small amount of the variation in attitudes towards wind energy. Recommendations for energy policy and future research are discussed.
The Impact of Abnormal Lipid Metabolism on the Occurrence Risk of Idiopathic Pulmonary Arterial Hypertension

The aim was to determine whether lipid molecules can be used as potential biomarkers for idiopathic pulmonary arterial hypertension (IPAH), providing important reference value for early diagnosis and treatment. Liquid chromatography–mass spectrometry-based lipidomic assays allow for the simultaneous detection of a large number of lipids. In this study, lipid profiling was performed on plasma samples from 69 IPAH patients and 30 healthy controls to compare the levels of lipid molecules in the 2 groups of patients, and Cox regression analysis was used to identify meaningful metrics, along with receiver operator characteristic curves to assess the ability of the lipid molecules to predict the risk of disease in patients. Among the 14 lipid subclasses tested, 12 lipid levels were significantly higher in IPAH patients than in healthy controls. Free fatty acids (FFA) and monoacylglycerol (MAG) were significantly different between IPAH patients and healthy controls. Logistic regression analysis showed that FFA (OR: 1.239, 95%CI: 1.101, 1.394, p < 0.0001) and MAG (OR: 3.711, 95%CI: 2.214, 6.221, p < 0.001) were independent predictors of IPAH development. Among the lipid subclasses, FFA and MAG have potential as biomarkers for predicting the pathogenesis of IPAH, which may improve the early diagnosis of IPAH.
Event‐triggered adaptive control for a class of switched nonlinear interconnected systems

In this article, the adaptive event‐triggered control issue is researched for a kind of switched nonlinear interconnected systems subject to unknown backlash‐like hysteresis and control coefficients. The fuzzy logic systems (FLSs) are employed to approximate the unknown nonlinear functions. To deal with the unknown control coefficients, the Nussbaum method and adaptive control are introduced. The proposed event‐triggered controller can effectively lessen the communication burden, meanwhile, the Zeno behavior is eliminated. It is guaranteed that the system outputs can track the reference signals and all the system signals are semi‐globally uniformly ultimately bounded (SGUUB). Finally, the simulation results verify the effectiveness of this control scheme.
The effect of premium income, expenses claim, and underwriting on profitability of Indonesia joint enterprises insurance companies

Purpose – This research has purposes to scrutinize over the role of premium income, expenses claim and underwriting results towards profitability of Indonesia Joint Enterprises Insurance Companies. Design/methodology/approach – The sample used is general insurance company that presents complete financial statements during 2018-2021 and listed by Otoritas Jasa Keuangan through its official website. Purposive sampling used as sampling technique with several samples are 48 data. Panel data regression used as analysis technique which then processed by Eviews-9 application. Findings – Its results showed that only underwriting results which significantly affect on profitability, while the others variables such as premium income had significantly negative affect on profitability so did with the expense claims which turn out had no affect towards profitability. At the level of significance (α = 0.05), it has small effect, while at the significance level of (α = 0.10), the expense claims seem had significant negative affect on profitability of Indonesia general insurance industry. Research limitations/implications – This research has certainly limitations such as the research object used relatively small only the joint general insurance companies which submitted complete financial reports which are listed by Otoritas Jasa Keuangan and followed by the company’s official website. Practical implications – This research indicates that those companies are noticed about an increase in premiums, but on the other hand they have also received many claims, therefore those premiums will be diverted to finance the claims which occur lately, then this certainly would decrease an income or profitability of the insurance company itself. Originality/value – This research also has a different research object and research period compared to previous research, therefore it can be used as a complement the research which have done before.
Hyperspectral Imaging Based Corrosion Detection in Nuclear Packages

In the Sellafield nuclear site, Cumbria, U.K., intermediate-level waste and special nuclear material are stored above ground in stainless steel packages or containers, with thousands expected to be stored for several decades before permanent disposal in a geological disposal facility. During this intermediate storage, the packages are susceptible to corrosion, which can potentially undermine their structural integrity. Therefore, long-term monitoring is required. In this work, hyperspectral imaging (HSI) was evaluated as a nondestructive tool for detecting corrosion on stainless steel surfaces. Real samples from Sellafield, including stainless steel 1.4404 (known as 316L) and 2205 plates from the Sellafield atmospheric testing corrosion site, were imaged in the experiments, measuring the spectral responses for corrosion in the visible near-infrared (VNIR, 400–1000 nm) and short-wave-infrared (SWIR, 900–2500 nm) regions. Based on the spectral responses observed, a new concept denoted as corrosion index (CI) was introduced and evaluated to estimate corrosion maps. With the CI, every pixel in the hyperspectral image is given a value between zero and one, aimed at representing corrosion intensity for a given location of the sample. Results suggest that HSI, combined with our proposed CI analysis techniques, could be used for effective automated detection of corrosion in nuclear packages.
Education and Fertility: A Review of Recent Research in Europe

This paper reviews research on education and childbearing in Europe over the last decade. Early demographic research attributed declining fertility in advanced economies in the second half of the twentieth century to increasing female educational levels. The twenty-first century has witnessed further increases in educational attainment coupled with trend reversals in fertility. The relationship between education and fertility has become more complex, sparking renewed interest in the interplay between the two life domains. We examine how educational enrolment and attainment influence individuals’ fertility behaviour – both fertility timing and level – and how the relationship between education and fertility is shaped by contextual factors such as family policies, macroeconomic shocks, and normative changes in gender attitudes. We also summarise the recent literature on educational gradients in male fertility and review methodological developments to address issues of self-selection and unmeasured heterogeneity in the study of education and fertility. Finally, this paper identifies and discusses challenges and important areas for future research.
