Incentivizing of inside sales units — the interplay of incentive types and unit structures

Abstract Although companies are increasingly deploying inside sales units, knowledge is scarce regarding how to effectively incentivize them. In addressing this neglect, this study draws on network theory to scrutinize how various unit and individual financial and non-financial incentives affect inside sales units’ performance. In addition, the authors examine the contingent roles of two unit-level network measures, density and centralization. Using data from 366 salespeople working in 118 inside sales units, the authors empirically test the predicted relationships. Results reveal that unit incentives are positively related to unit performance, whereas individual incentives notably have a negative relationship with unit performance. Results further reveal that both density and centralization influence the incentive–unit performance relationships. Overall, findings indicate that the effects of various incentives in the inside sales unit context differ from those in other contexts, resulting in important implications for managers.
Portraits of teachers in neoliberal times: projections and reflections generated by shadow education research

ABSTRACT Shadow education (or private supplementary tutoring) has grown exponentially both as a phenomenon and an area of research. Based on a qualitative content analysis of international research on private tutoring published in the last four decades (1980–2018), this study explores how teachers and their teaching practices are represented in this literature and what such constructions mean for teacher professionalism. The findings reveal a variety of competing views about school teachers and the teaching profession, reflecting a partial and particular conception of the teaching profession. Influenced by the neoliberal logic, many of these projections portray teachers who participate in tutoring activities as corrupt or narrowly frame their work in terms of profit, competition, or entrepreneurship. Given that most of the reviewed research does not draw on teachers’ own perspectives, we call for more nuanced and multidimensional approaches to understanding teachers’ complicated roles and negotiations in this time of neoliberal globalisation.
High-Temperature Oxide and Hydroxide Vapor Species of Technetium

In order to better characterize the high-temperature chemistry of technetium, its oxide was exposed to low pressures ( ~ 10 Pa) of oxygen and/or water vapor up to 1100°C in a platinum Knudsen cell reactor. The resulting volatile products were identified mass spectrometrically. The significant technetium vapor species identified from the mass spectra were the following: Tc03(g), Tc207(g), Tc03(0H)(g), Tc2Os(g) and Tc02(0H)3(g); the last two of these were previously unreported. The identification of these species and their relative concentrations are discussed, and comparison is made with the corresponding hightemperature chemistry of homologous rhenium.
Exploiting weighted association rule mining for indicating synergic formation tactics in soccer teams

Managers make decisions on team tactics, formations, and player selection based on their own experiences. The managers have limitations in understanding the team's situation and sometimes they can think wrong. The purpose of this study is to make decisions on player selection and tactical formation according to the level of the opponent based on the data, not on the intuition of the manager. In our previous study, the Boruta algorithm was used to extract important features from 69 features in soccer player data by position. The detailed roles of each position were defined by using K‐means algorithm. For example, the detailed roles of each position were defined as Mezzala, Shadow Striker, Deep‐lying playmaker, and so on. That is, forward positions are classified as Target Man (TM) and Shadow Striker (SS). TM is a high‐goal, high‐competitive forward, and SS is a high‐dribble, high‐pass forward. In this study, we analyze a clustering dataset and the game appearance dataset. The game appearance dataset are divided into CL (Champions league Level), EL (Europa league Level), ML (Middle Level), and RL (Relegation Level). Association rule mining algorithm analyzes the synergy between positions, and selects a position with high synergy. Weighted association rule mining algorithm establishes player selection and tactical formation with the weight, which is the player's rating data. Finally, using the obtained results, we visualize the synergy between positions, tactical formation, and player characteristics depending on the level of the opponent.
Managers' and auditors' narcissism on the management team's stability and relative corporate performance

PurposeSuccess in corporate relative performance is one of the factors for the growth and durability of firms. Since the relative performance is a function of managers' decisions and such decisions are under the influence of behavioral and psychological characteristics, this paper aims to assess the managers’ and auditors’ narcissism's effect on the management team's stability relative to corporate performance.Design/methodology/approachThis paper has used the signature magnitude for examining narcissism and the regression model of Jenter and Kanaan (2015) for assessing relative corporate performance. The logistic regression is used to test the model of the management team's stability, and the multivariate regression is used to test the model of relative corporate performance. Research hypotheses were also examined using a sample of 768 listed year-companies on the Tehran Stock Exchange during 2012–2017 and by employing a panel data approach and fixed effects method.FindingsThe obtained results show a negative and significant relationship between managers' and auditors' narcissism and the management team's stability. The relationship between the narcissism of managers and auditors and relative corporate performance is positive and significant. Moreover, managers' narcissism positively and significantly impacts the relationship between auditors' narcissism and team management stability. A negative and significant relationship is evident between auditors’ narcissism and relative corporate performance.Originality/valueThis study's results can identify the effect of psychological components such as narcissism on people's performance by directing and influencing their decisions. Many studies have been conducted on narcissism, but none of them have examined the impact auditors’ and managers' narcissism has on the management team's stability and the corporate relative performance. Therefore, considering the importance of success in the corporate relative performance and benefits of the management team's stability, this study's results can reveal the importance of such features in accounting research. Also, the results of this research can make it important to know more about financial behavioral theory.
Surface complexation modeling of U(VI) sorption on TiO2 in the presence of fulvic acid

Abstract In this work, experiments and modeling for the interactions between uranyl ion and TiO2 in the presence of fulvic acid are presented. The results demonstrated that FA is strongly bound to TiO2, and these molecules have a very large effect on the U(VI) sorption, and vice versa. The results also demonstrated that U(VI) sorption to TiO2 in the presence and absence of sorbed FA can be well predicted with the SCD model (surface and complex distribution). According to the model calculations, the nature of the interactions between FA with U(VI) at TiO2 surface is mainly surface complex and electrostatic potential.
A new divide? Assessing the transnational-nationalist dimension among political parties and the public across the EU

European politics is increasingly being contested along two dimensions: the economic left-right dimension and a relatively new dimension focused on European integration and immigration. We test this framework at the party and individual-levels in the European Union. First, we use the Chapel Hill Expert Survey to demonstrate that there is no simple relationship between these dimensions at the party level in many European Union countries, and in fact the two dimensions are increasingly orthogonal. We then use the 2019 European Elections Study to show that the transnational-nationalist dimension significantly improves vote choice models relative to models that ignore this dimension. Even more striking, the transnational-nationalist dimension is not just significant, but actually improves vote choice models as much or more than the economic left-right dimension.
Pediatric Ocular Trauma From A Tertiary Public Hospital in Colombia: Epidemiological Characterization

BackgroundEye injury is a serious public health problem being in the world, that causes unilateral blindness, a particular condition in children due to the functional impact and psychosocial implications. The eye injury can be prevented thanks to the identification of risk factors associated with the socio-cultural context, this aspect has motivated studies in the pediatric population in United States, India, Australia, Cuba, Egypt, United Kingdom, Brazil, Colombia, Marathwada and Canada, among others. So the objetive of the present study is to describe the sociodemographic and epidemiological characteristics of pediatric eye injury and its effects on ocular structures in a tertiary public hospital from Colombia.MethodA retrospective cross-sectional study was carried out between January 1, 2015, and December 31, 2017, in a tertiary public hospital of a medium-sized city located in the Northeast of Colombia. Children under 15 years old with trauma to the eyeball or its adnexa were included. The Birmingham Eye Trauma Terminology System (BETTS) was used. Eye burns and Ocular adnexa were also included.Results61 cases of eye injuries were recorded, 67.21% (41 cases) of which were males. 57.37%(35 of the cases) corresponded to closed-globe injuries both contusion and lamellar laceration. Visual acuity fluctuated between 20/20 and 20/40. 14.75% (9 cases) were Open-globe injuries while 50% (4 cases) were penetrating trauma. 27.86% of the injuries (17 cases) did not directly compromise the eyeball, 58.82% (10 of these cases) of which corresponded to eyelid wounds, and neither of those had the visual acuity informationConclusionThe study showed that the majority of eye traumas are closed globe, caused by
Theoretical and experimental evidence on stock market volatilities: a two-phase flow model

Abstract The volume–volatility relationship usually ignores possible effects of stock shares. This article proposes a two-phase flow model assuming that capital and stock flows determine stock price and return volatility. Computational simulations suggest that monodirectional capital or stock flows and collective flows exert different effects on stock return volatilities. Considering the impact of stock flows, the positive relationship between capital and return volatility is no longer guaranteed. The inflow of capital and the outflow of stock increase stock price similarly; but exhibit completely different effects on stock return volatilities. A persistent stock inflow (outflow) reduces (intensifies) return volatilities, whereas a monodirectional persistent capital outflow has no such effect. When capital and stock flows’ velocities satisfy critical values determined by the initial state of the market, the market enlargement accompanied with increasing stock and capital shows no impact on market stability because of stable return volatilities. Otherwise, stock flows drive return volatilities with stronger effects than capital flows. Further experimental studies that simulate the real stock market through a trading system provide strong evidence supporting the two-phase flow model. Given similar driving forces of capital and stock flows, the interaction of them should be considered in constructing investment strategies and setting policies.
Experimental Study on the Behaviours of Post-tensioned Concrete Members with Unbonded Tendons

This paper presents experimental results regarding the behaviours of eight simply supported partially prestressed concrete beams with internally unbonded tendons, focusing particularly on the effect of three different variables: concrete compressive strength, fc ′; jacking stress, fj ; and the prestressing index, ω. Increasing the concrete compressive strength from 35 MPa to 60 MPa was seen to lead to an increase in load-carrying capacity by about 10%. The load capacity was also affected, though to a lesser extent, by the jacking stress. The failure load of partially prestressed concrete beams with internally unbonded strands was increased by about 2.5%, to 10%, when the jacking stress increased from 0.5 to 0.7 of the strand’s ultimate strength, fpu . The test results showed that the prestressing index was the most influential parameter among the examined variables. The experimental results of the stress increase in unbonded strands at failure and the ultimate load resistance of members were also compared to the analytical results of various standards and research methodologies for verification.
Prevalence, predictors and associations of complex post-traumatic stress disorder with common mental disorders in refugees and forcibly displaced populations: a systematic review

ABSTRACT Background: The inclusion of complex post-traumatic stress disorder (CPTSD) in ICD-11 represents a turning point for the field of traumatic stress, with accumulative evidence of this disorder in refugees and displaced populations. Objective: The objectives of this systematic review are to examine, in refugee and displaced populations: 1) the prevalence of CPTSD; 2) factors contributing to CPTSD; and 3) and associations between CPTSD and other common mental disorders including: PTSD, depression, anxiety and somatisation. Method: We followed the Joanna Briggs Institute Methodology for Systematic Reviews. Papers published in English language were included, with date of publication between 1987 and June 2019. We searched six relevant databases: MEDLINE, PsycINFO, Embase, Scopus, CINAHL, and PILOTS, and the grey literature. We included observational studies with prevalence data on CPTSD. Results: 19 articles met all inclusion criteria. Quality assessment was performed on each included study using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data. Based on this, 13 moderate and high-quality studies were included in our narrative synthesis. The included studies reported prevalence of CPTSD in refugees and displaced populations ranging from 2% to 86%. Conclusions: Reasons for the wide variation in prevalence may include contextual and geographical differences, the influence of post-migration difficulties, and sample population characteristics such as treatment seeking versus general population. We found higher prevalence rates (range: 16–82%) in more studies with treatment seeking samples, followed by convenience and snowball samples (40–51%), and lower rates in more studies utilising random sampling techniques (2–86%). Consistent with the broader literature, the studies in our review supported an association for complex post-traumatic stress disorder with prolonged, repeated trauma, and post-migration living difficulties, with the latter association being specific to refugee and displaced populations. Further research on this construct in this population group, including effective treatments, is required. HIGHLIGHTS • Complex traumatic stress disorder in refugees and forcibly displaced populations.
A new perspective of innovation-driven agricultural sustainable development: a case of China

The experience of many countries shows that the agriculture relying on factors input is unsustainable and technological innovation is the support for improving productivity and comprehensive strength. In the critical period of transformation and upgrading, China's launch of an innovation-driven development strategy which is an inherent demand for the sustainable development of multiple industries, including agriculture. Among the entities undertaking this task, innovation-driven agricultural subjects are an important carrier. However, due to the inherent limitations and high risks of technological innovation, they are subject to strong constraints under the traditional model. In order to solve this bottleneck, innovation-driven agricultural subjects have a strong desire to seek innovation channels, and agricultural crowdfunding mode meets their requirements.
An Evaluation of Massive Land Interventions for the Relocation of Capital Cities

Across the world, capital cities are being relocated. Such practices have existed almost as long as capitals themselves. Against the background of the relocation of Indonesia’s seat of government from Jakarta to East Kalimantan, it is clear that such processes will continue to take place in the future. Especially if one considers the reasons for the move: climate change is leading to an increasing inhabitability of the Indonesian capital. Therefore, it is important to understand the processes behind such megaprojects and their impacts on the surroundings in order to build new capitals sustainably. Hence, this paper deals with examples from the past seven decades and examines them from different perspectives, such as the underlying politics and economy, planning approaches, reasons for relocation, as well as cultural and ecological backgrounds. With an analytical methodology based on eight aspects of responsible land management interventions (the 8R-framework), it is possible to assess the degree to which these moves are responsible. Combined with a literature review of past documented evidence, we derived 8R-matrices, inferred recurring issues and constructed a database containing multiple aspects of capital relocations. This database allowed simple SQL-coding, which enabled describing commonalities among the different land interventions for the capital relocations. These results help to connect occurring sets of problems to particular political, economic and planning backgrounds and to identify different frameworks within which most new capitals are situated. These new insights make future capital relocations better manageable and can support the process of capital relocation in Indonesia.
The effect of warm additive on the properties and behavior of an asphalt binder

ABSTRACT Use of warm asphalt mix has been recently receiving a great attention because it allows decreasing production and distribution temperatures about 30–40°C by either reducing bitumen viscosity or enhancing mixture performance. These mixes also have other advantages such as a low pollution, reduced fuel consumption, and more implementation seasons. Despite these benefits, there is a constant concern about the performance of these mixes under the conditions such as permanent deformation, fatigue cracking, and low-temperature cracking. In the present study, two types of bitumen modifiers including liquid additive and Sasobit were used to adjust rheological properties of bitumen. After conducting the required tests on bitumen specimens prepared using these two additives and comparing the results obtained from two common and Strategic Highway Research Program tests under aged and nonaged conditions, it was revealed that, considering the viscosity of bitumen, these additives improve bitumen performance at ambient temperatures. Besides, the results indicate the improvement in rutting criteria (G*/sinδ) and fatigue criterion (G*×sinδ).
Optimization of dyeing process variables for eco-friendly dyeing of cotton fabric with babul bark extract as a natural dye and gallnut extract as a bio-mordant

ABSTRACT In the present study, cotton fabric has been dyed with aqueous extract of babul bark (Acacia nilotica) using gallnut (Quercus infectoria) as bio-mordant containing hydrolyzable tannins like gallic acid, elagic acid and polyphenolic gallotannins to produce light yellow color. On the other hand when gallnut bio-mordanted cotton is subsequently dyed with babul bark extract as a natural dye containing similar but non-hydrolyzable tannin-rich color component including small amount of catechin and epi-gallo-catechin, it produces a medium to deep brown color through formation of giant insoluble colored complex of cotton-gallotannins (gallnut)-catechin/epigallocatechin and other color components present in babul bark extract. The process variables for extraction, pre-mordanting and dyeing have been optimized to standardize this dyeing technique. Scattered CDI values for dye-bath pH and dye concentration identified them as the most important dyeing parameters that need to be controlled for obtaining uniform dyeing. High UPF value of upto 35 rendered by application of both gallnut and babul bark through preferential absorption of UV light by the gallotannins in both gallnut and babul bark indicates good UV protection properties of dyed cotton fabrics.
Depth Constraints on Coseismic Velocity Changes From Frequency‐Dependent Measurements of Repeating Earthquake Waveforms

We revisit velocity changes caused by the 2004 Parkfield earthquake through the analysis of the coda of repeating earthquakes. Our results reveal the change to be strongly frequency dependent. Low‐frequency components of the coda of repeating earthquakes are more affected by the velocity alteration than high‐frequency components. We interpret this to indicate that the coseismic velocity reduction primarily occurs at a shallow depth, and is expressed in low‐frequency energy resulting from reverberations near the Earth's surface. This can only be observed at low frequencies because the shallow crust is highly dissipative. The high‐frequency component is relatively unaffected, as it is comprised of body waves scattered throughout the crust. We support this argument with direct observations of seismic wavefields across a wide range of depths in the shallow crust, supplemented by using downhole geophones and distributed acoustic sensing measurements.
Ultrasonic and thermographic fatigue monitoring on a full-scale CFRP aeronautical component after repairing

The identification of defects in real components made in composite material assumes considerable importance in the aeronautical field, as irregularities in the material can compromise its functionality. Also, the possibility (NDT) to verify the effectiveness of repairing on the component during exercise through non-destructive testing techniques has great importance. The goal of the present study is the application of the ultrasound and thermographic techniques for the identification of defects in a repaired component and the evaluation of the damage caused by the application of cyclical fatigue loads. All the important factors were studied, improving ultrasound scanning and allowing evaluating the effectiveness of the techniques used. In this paper, one case of study was proposed for non-destructive damage evaluation employing Phased Array ultrasonic and thermographic methods on aeronautical CFRP component. The structural element analysed is a spar with a double-T section with a hole and presents a repair by scarfing and hot bond process. The experimental results obtained shown the validity of the ultrasonic and thermographic technique for the sensitivity in detecting defects on full-scale aeronautical components with short execution and scan times.
