El presente trabajo caracteriza la afectación al patrimonio inmueble y turismo ocasionado por la actividad minera ilegal desarrollada en cantón Zaruma, Provincia de El Oro, conocida como aquella ciudad que posee emblemáticos patrimonios culturales y cuya economía se basa en gran parte a la explotación minera. Siendo esta actividad una problemática para sus habitantes y entorno, puesto que, se desarrolla de forma ilegal y crea consecuencias irreparables para el medioambiente; La explotación minera ha estado presente desde años remotos generando así un descontrol en la parte alta de la Provincia. Por ello, el objetivo central de la investigación es analizar la afectación de la minería sobre el patrimonio inmueble y con ello su repercusión al sector turístico. Por consiguiente, se enfatizó una investigación descriptiva, tomando una visión general para la explicación de la problemática y mediante la aplicación de una metodología mixta, que a través del uso de instrumentos de recolección de datos como lo es la encuesta y entrevista a los pobladores y a su vez la ejecución de la técnica de observación, por lo que, en ese sentido los resultados determinan que en conclusión que la minería ilegal ha afectado directamente a los bienes patrimoniales esencialmente al patrimonio inmueble y con ello también ha afectado al sector turístico dado que siendo el patrimonio inmueble uno de los principales atractivos de Zaruma, evidentemente el turismo se ha visto aminorado generando así la pérdida de puestos de trabajo, pérdida de ingresos, entre otros.

Background: Despite many publications on rehabilitation after repair of flexor tendon injuries of the hand, there is no consensus as to which method is superior. It is clear that nonadherence to postoperative therapy adversely affects the outcome after flexor tendon surgery. In the context of a developing country, the most important factor associated with poor outcome is late onset of rehabilitation therapy. An autonomous rehabilitation program is proposed, with the use of a low-cost splint and based on an online illustrative video with the expectation to improve adherence and patient compliance, thus ensuring satisfactory outcome. Methods: Twenty-two consecutive digits of 14 patients after flexor tendon repair in zone II were included. Autonomous early passive mobilization physical therapy and splinting started shortly after surgery, supported by an online available video depicting prescribed exercises; follow-up was continued until postoperative week 20. Patients were evaluated regarding range of motion, grip strength, and the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) disability scale. Results: Range of motion after 20 weeks according to the scoring system of the American Society of Surgery of Hand was excellent in 4, good in 11, and fair in 4 fingers. The mean total active motion score was 86% (95% confidence interval, 78%-93%). The mean grip strength at final follow-up was 86% of the contralateral hand. The mean QuickDASH score was 12.5 (2.3-31.8). Conclusion: This protocol achieves good results in range of motion and early return of function of the hand. We propose this simple, nonexpensive method to developing countries with less than optimal availability of health care.

El presente estudio tuvo como objetivo desarrollar el proceso de galletería sin gluten, utilizando como materia prima principal la avena, miel de abeja y quinua, las mismas que fueron parte de las recetas en las variedades de sucreé, briseé y sablée. La metodología fue experimental, con diferentes tratamientos para poder identificar la mejor forma de aplicar la formulación, en los resultados pudieron desarrollarse de manera bastante interesante gracias a la versatilidad de la avena pulverizada y la harina de quinua, en vista de que su valor nutricional es ausente de gluten y por las características de la galletería. Como conclusión, cabe mencionar que la avenina se caracteriza por ser una proteína potencialmente nociva para el celíaco, pero al compartir contenido con la harina de quinua disminuye el riesgo de intoxicación por parte de este producto generando de esta manera una alternativa de alimentación para las personas intolerantes al gluten.

Human actions compromise the many life-supporting functions provided by the freshwater cycle. Yet, scientific understanding of anthropogenic freshwater change and its long-term evolution is limited. Using a multi-model ensemble of global hydrological models, we estimate how, over a 145-year industrial period, streamflow and soil moisture have deviated from pre-industrial baseline conditions (defined by 5th–95th percentiles, at 0.5° grid level and monthly time step). We find increased frequency of local deviations on ~45% of land area, mainly in regions under heavy direct or indirect human pressures. To estimate humanity’s aggregate impact on the freshwater cycle, we present the evolution of deviation occurrence at regional to global scales. Currently, local streamflow and soil moisture deviations occur on 18.2% and 15.8% of global land area, respectively, which is 8.0 and 4.7 percentage points beyond the ~3 percentage point wide pre-industrial variability envelope. Finally, we discuss applying our approach to define a planetary boundary for freshwater change. Our results indicate a substantial shift from stable pre-industrial streamflow and soil moisture conditions to persistently increasing change and a transgression of the freshwater change planetary boundary, calling for urgent actions to reduce human disturbance of the freshwater cycle.

Tropical Alpine Ecosystems are high-altitude grasslands located above 3000 m.a.s.l. along the tropical belt of three continents. Their unique vegetation and soil characteristics, in combination with low temperature and abundant precipitation, create the most advantageous conditions for regulating and storing surface and groundwater. However, increasing temperatures and changing patterns of precipitation due to greenhouse-gas-emission climate change are threatening these fragile environments, reducing their extent and modifying their altitudinal distribution range. Here, we investigate the impact of climate change on the distribution and extent of global Tropical Alpine Ecosystems. We use an ensemble of historical and projected climate data (SSP585) from seven General Circulation Models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) to estimate annual average values of temperature and annual accumulated values of precipitation for reference (1985-2014) and far future (2070-2100) 30-year periodos. We produced the 95% probability current and future hydroclimatic spaces for every ecosystem to determine the range at which Tropical Alpine Ecosystem currently thrives in the climatic space, and investigate a number of hydroclimatic variables. Then, we used the projected climate time-series data to assess the current Tropical Alpine Ecosystem areas that will be unable to keep up with the temperature and precipitation changes by exceeding their reference climatic boundaries in the far future. Overall, our results showed that the Tropical Alpine ecosystem would drastically reduce its extent. Approximately 45% of its current extent will experience hydroclimatic conditions beyond their reference climatic boundaries. For example, the Ethiopian montane moorlands in Africa will be the most impacted ecoregion with a reduction of approximately 95% of its current extent. For the case of páramos in the North of the South American continent, increasing temperatures and changing precipitation will render ~50% of the current extent unsuitable for these ecosystems during the dry season. Our results highlight the magnitude of the impacts of climate change on Tropical Alpine Ecosystem and the vulnerability of water security of millions of people who depend on its ecological functioning. These results also have implications for biodiversity conservation, as endemic species will be threatened by habitat reduction and shifts in their distribution ranges.

The loss of hydrological connectivity and fragmentation of natural wetlands have driven widespread wetland degradation worldwide. Monitoring techniques are needed to assess the degree of fragmentation and to aid with the restoration of affected wetlands. Hydrogeodetic tools such as wetland Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor wetland hydrology as it provides information on three-dimensional flow dynamics at a high spatial resolution. While this technique has been utilized previously for the manual assessment of hydrological connectivity in wetlands, this study proposes the first deep learning-based approach for the automated detection of barriers to the natural water flow that cannot otherwise be identified by conventional space imagery. To this end, a deep convolutional network is trained by segmenting edge features in ALOS PALSAR-1 L-Band InSAR images captured between 2006 and 2011. The training dataset consists of manually labelled and delineated barriers showing abrupt changes in water surface elevation and 22 wrapped interferograms with high coherence across several sample sites in the Everglades and the wetlands of southern Louisiana, United States. The scenes were processed in the Interferometric synthetic aperture radar Scientific Computing Environment (ISCE). The network is set up using a UNet structure with alternating convolutional and pooling or upsampling layers along a contracting and expanding part. The validation of the resulting pixel-wise segmentation shows that the network can successfully detect hydrological barriers in wetlands. Apart from identifying the location of barriers, the CNN can be applied to identify the type and persistence of the fragmentation over the entire wetland. Utilizing the multitemporal data additionally helps detect seasonal changes in the presence or absence of hydrological barriers in the sample sites. This study demonstrates the potential of deep learning techniques for the automated detection of hydrological parameters in InSAR imagery and sets the groundwork for the automated monitor of wetland fragmentation across the world.

Water availability can be linked to a country's stability, internal security, and the occurrence of violence and governability, in the environmental change context. For instance, lack of access to water resources can trigger political conflicts, be used as a tool for political negotiation or attacks on water infrastructure can be used as a source of intimidation. The potential political risks associated with water availability take particular relevance at the scale of international and transboundary hydrological basins and under conditions of water-food scarcity or political instability. To date, although water risks occurring within the boundaries of the hydrological basin have been studied across several case studies in the literature, the issue of risks arising from water upwind-downwind dependency has been overlooked. For instance, precipitation in a hydrological basin or agricultural centre regions with a high dependency on terrestrial moisture recycling may originate in upwind terrestrial areas outside of the basin boundaries. Here we study geopolitical risk related to this water dependency by analizing terrestrial moisture recycling. Our analysis shows that some hydrological basins in Africa, Asia and South America present a high risk of experiencing geopolitical conflicts when there is a large extension of croplands, high moisture recycling dependency and their precipitationsheds extend over warmongering countries. Hence, our results indicate that addressing transboundary water security from a surface perspective can underlook potential geopolitical conflicts that may threaten regional water-food security and peace. These risks need special international attention to guarantee global peace and agricultural production.

Research on the protection and preservation of wetlands has traditionally focused on direct human drivers and impacts of climate change occurring in their upstream hydrological basin. However, since precipitation falling in the hydrological basin comprises both oceanic and terrestrial evaporation originating mostly outside of the basin boundaries, upwind land use and hydroclimatic changes affecting this supply of precipitation also need to be assessed. This study assesses the vulnerability of 40 wetlands of international importance to land use and hydroclimatic changes occurring upwind (i.e., in their precipitationsheds). We here use a dataset containing atmospheric moisture flows in combination with evaporation from natural and current vegetation to analyse the impact of extra-basin vegetation changes on the precipitation over the wetland basins. The analysis shows that historical land-use conversion has already caused reduced incoming precipitation into most wetland hydrological basins. The strongest effects are seen in (sub)tropical wetlands in South America, Africa and Asia and especially those located downwind of large agricultural areas. Based on our results and current wetland decline rates, we find that wetland sites in China, India, South America and Sub-Saharan Africa are especially threatened by hydroclimatic and vegetation changes outside of their basins. Additionally, larger basins appear to be more reliant on evaporation from within their basin boundaries than smaller hydrological basins. Using wetland ecosystems as an exemplary case, this study stresses the need to incorporate downwind effects to land-use changes in sustainable ecosystem management approaches. Since the transition from potential natural vegetation to agricultural land is often associated with changes in evaporation, land conversion may affect the resilience of wetland water availability. Following this analysis of the upwind moisture sources of wetland basins, future studies should investigate the potential effect of wetland loss on downwind precipitation patterns.

The purpose of the research is to determine the relationship between the teaching attitude associated with new information and communication technologies in times of the COVID-19 pandemic. For this, a quantitative, basic approach was applied, with a hypothetical-deductive method, non-experimental design, correlational descriptive. The sample consisted of 105 primary school teachers from UGEL No. 15. The technique applied was a survey through two questionnaires, validation through expert judgment, and reliability was determined with Cronbach's Alpha coefficient (0.97). According to the results, it was obtained that the Spearman's Rho correlation coefficient equal to 0.656 and the significance is ρ = 0.01 (ρ < 0.05), so the null hypothesis is rejected and it is accepted that there is a direct relationship between attitude teacher and the use of new information and communication technologies in times of pandemic by COVID-19.

La violencia es considerada como toda acción que usa la fuerza física o abuso del poder en contra de la integridad de una persona o de uno mismo, la cual se encuentra en relación con factores biológicos, psicológicos, estructurales, sociales, entre otros. Muchas de las veces la gran parte de la población desconoce de estos temas, convirtiéndose en un problema que se suscita a diario a nivel mundial.

The global target to protect 30% of Earth’s land and ocean by 2030 has prompted governments to report their progress in biodiversity conservation. Announcements of countries reaching 30 % of conservation area are widely commended by the international community, despite signs of increasing pressures within protected areas, poor representativity of key threatened ecosystems, and a lack of indicators to monitor the impact of conservation areas on people. Using Colombia’s experience, we urge megadiverse countries to report indicators of how conservation actions at local scales impact global outcomes, how other effective area-based conservation measures (OEMCs) enhance the impacts of the existing protected area network, and how conservation areas promote an equitable and efficient distribution of benefits to people.

This chapter presents collaborative peace education as a perspective to the development of capacities for conflict transformation in countries that have experienced socio-political violence. For this, it takes the Colombian violence as a context to integrate principles of peace education, conflicts transformation, social constructionism, and collaborative practices in order to establish working premises and ideas for scenarios where strengthening a culture of peace is required. From the revision of these concepts, the authors propose four principles that support the collaborative peace education, some contents that can be developed in an initiative of this type and relevant ideas to choose the format to be used in a collaborative peace education program.

HSCs were isolated from umbilical cord blood, MSCs were isolated from human bone marrow and a microvasculature EC line (CC-2811, Lonza®) was used. For the formation of a 3D structure, a magnetic levitation culture system was used. Cultures were maintained in 21%, 3% and 1% O2 for 15 days. Culture volume, sphericity index and cell viability were determined. Also, human HSC proliferation, phenotype and production of reactive oxygen species were evaluated.Results: After 15 days, 3D-MS exhibited viability greater than 80%. Histology results showed structures without necrotic centers, and higher cellular proliferation with 3% O2. An increase in the expression of the CD34 antigen and other hematopoietic antigens were observed to 1% O2 with MSCs plus ECs and low ROS levels.Conclusion: These findings suggest that 3D-MS formed by MSCs, ECs and HSCs exposed to low concentrations of oxygen (1– 3% O2) modulate human HSC behavior and mimics some features of the perivascular niche, which could reduce the use of animal models and deepen the relationship between the microenvironment of HSC and human hematological diseases development.Keywords: hematopoietic stem cells, niche, bone marrow, microenvironment, 3D culture

Study region: Selenga River Delta (SRD), Russia. Study focus: How is water occurrence changing in the SRD, and what are the hydroclimatic drivers behind these changes? The presence of water on the surface in river deltas is governed by land use, geomorphology, and the flux of water to and from the Delta. We trained an accurate image classification of the Landsat satellite imagery during the last 33 years to quantify surface water occurrence and its changes in the SRD. After comparing our estimations with global-scale datasets, we determined the hydrological drivers of these changes. New hydrological insights for the region: We find mild decreases in water occurrence in 51% of the SRD's surface area from 1987–2002 to 2003–2020. Water occurrence in the most affected areas decreased by 20% and in the most water-gaining areas increased by 10%. We find a significant relationship between water occurrence and runoff (R2 =0.56) that does not exist between water occurrence and suspended sediment concentration (SSC), Lake Baikal's water level, and potential evapotranspiration. The time series of water occurrence follows the peaks in the runoff but not its long-term trend. However, the extremes in SSC do not influence surface water occurrence (R2

Este estudio combina análisis socio-históricos y funcionales, bajo una perspectiva regional, de una microcuenca hidrológica; intenta entender los patrones de uso pasados e identificar debilidades y fortalezas hacia un plan de manejo integral del territorio y el agua. El análisis reveló que, en términos del funcionamiento, esta microcuenca depende de un sistema de flujo regional y conexión a otras microcuencas adyacentes, y que las interrelaciones entre los componentes natural y social, así como los movimientos ciudadanos organizados fueron aspectos clave en el rescate de la microcuenca y en la creación de un programa de manejo dinámico adaptativo.

PurposeThe purpose of this paper is twofold: first, to examine a customer orientation mechanism through which abusive supervision influences retail salespeople’s job performance; and second, to investigate how abusive supervision’s effects may be moderated by the same leader’s use of contingent punishment and contingent reward.Design/methodology/approachTwo studies provide consistent findings. Study 1 used the field survey data from 129 salespeople in 42 retail stores. The proposed moderated mediation model was estimated using the random coefficient modeling technique. Findings were replicated in Study 2, in which data were collected from a sample of 679 US retail salespeople recruited through M-Turk.FindingsResults from both studies show that abusive supervision reduces salespeople’s job performance through lowering their customer orientation. Furthermore, the use of contingent punishment from the same supervisor buffers abusive supervision’s detrimental effect, whereas the use of contingent reward augments it.Research limitations/implicationsThe issues the authors address in this research have significant implications for the literature of abusive supervision and retail selling. First, the authors contribute to the abusive supervision literature by pointing it out that the negative effect of abusive supervision can spill over to organizations’ external stakeholders, namely, customers. Previous research on abusive supervision has mainly focused on how abused subordinates exhibit hostile acts directed against the supervisor, coworkers and the organization (Tepperet al., 2017), with little attention paid to abusive supervision’s impact on organizations’ external stakeholders such as customers. This research fills the void by placing impaired customer-orientation as a critical consequence of abusive supervision. Second, this research tests a contingent self-regulation impairment model of abusive supervision and advances our understanding about how the same supervisor’s functional leadership behaviors (contingent reward/punishment) may set contingencies for the effect of abusive supervision on employee outcomes. This investigation clears the doubts about whether the use of functional leadership behaviors along with abusive supervision buffers or aggravates the detrimental effect of the latter. Finally, this study’s findings shed new insights to marketing practitioners, especially in understanding how salespeople may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. This research shows that abusive supervision can lower employees’ customer orientation, which will hurt the company in the long run.Practical implicationsThe findings intend to provide important guidelines for companies to develop effective workshops and training programs to combat the detrimental effects of abusive supervision in the retailing industry. For example, the findings shed new insights in understanding how employees may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. Another important managerial implication of this research is that the use of contingent reward after mistreating subordinates can backfire. Supervisor abuses, followed by a contingent reward, send an inconsistent signal to the employee that creates confusion and strain. Inconsistent actions from the supervisor also produce ethical tensions that reduce customer-oriented behaviors and a company’s ability to serve the customer (Friend et al., 2020). These training programs are important methods to combat the detrimental effects of abusive supervision in the workforce.Originality/valueThis research draws on the contingent self-regulation impairment model as an overarching framework to unpack the relationship between abusive supervision and salespeople’s job performance. Integrating three research streams (i.e. abusive supervision, leadership reinforcement and retail selling), this study proposes customer orientation as a novel mechanism and sheds light on how abusive supervision interplays with contingent punishment/reward to impact salespeople’s outcomes.

We use a dynamic international trade model to analyse the implications of international trade for agents’ preferences and economic growth. This model is based on the home market effect with external habit formation (“catching up with the Joneses”) and “learning by doing” in production. We demonstrate the following: the historical composition of consumption in countries determines industrialization after trade; the preferences of agents converge after trade, independent of the economic results; and the welfare effects of trade may be positive or negative depending on trading partner characteristics. In some scenarios, autarky is strictly preferred to trade. Thus, international trade does not necessarily imply greater welfare, as is the typical result in a static context under CES preferences.

Long-term customer relationships develop over repeated interactions, underscoring the importance of frontline employees (FLEs) engaging in ethical behaviors. Therefore, organizations must understand how a strong ethical climate (EC) may affect attitudes and behaviors among FLEs. This study reviews frontline-related EC research and employs a meta-analytic approach to investigate the direct, indirect, and contingent effects of EC on FLE actions, attitudes, and outcomes. The authors reviewed 67 frontline-related studies comprising a sample of 21,118 respondents to assess meta-analytic associations and derive a model for structural testing. The findings from this study show that a strong EC drives customer-oriented behaviors, fosters desirable job attitudes, reduces felt stress, increases perceived performance, and decreases turnover intentions among FLEs. The strength of theses associations is often predicated on individual-level (FLE experience), study-level (response rate), and country-level (perceived corruption, individualism/collectivism) factors. This study offers theoretical and managerial contributions germane to multiple uncertainties in service literature about EC’s implications on FLEs, including EC’s ability to break through sources of tension-facing FLEs, the mediated nature of EC’s impact on perceived performance through frontline actions, and the generalizability of the economic and human benefits of EC across service contexts and frontline roles that foster greater diffusion in practice.

The objective of the present study was to report the resting and lying behaviour of hospitalised horses, and whether lying behaviours differ depending on the physiological severity of joint damage. We hypothesised that the resting and lying behaviour can change during the hospitalisation and physiological severity of joint damage affect the time of rest in horses. A descriptive observational study was performed to evaluate the effect of hospitalisation on the recumbency time of 8 adult horses with different degrees of osteoarthritis of the metacarpophalangeal joint. The horses’ rest time was monitored using cameras during the first 5 days of hospitalisation. The total time of lateral recumbency and frequency of recumbency were greater after the 4th day of hospitalisation (P

The Budyko framework consists of a curvilinear relationship between the evaporative ratio (i.e., actual evaporation over precipitation) and the aridity index (potential evaporation over precipitation) and defines evaporation’s water and energy limits. A basin’s movement within the Budyko space illustrates its hydroclimatic change and can help identify the main drivers of change. Basins are expected to move along their Budyko curves when only long-term changes in the aridity index drive changes in the evaporative ratio. We hypothesize that the increasing effects of global warming on the hydrological cycle will cause basins to move along their Budyko curves. To test our hypothesis, we quantify the movement in Budyko space of 353 river basins from 1901 to 2100 based on the outputs of nine models from the Coupled Model Intercomparison Project - Phase 5 (CMIP5). We find that significant increases in potential evaporation due to global warming will lead to basins moving primarily horizontally in Budyko space accompanied by minor changes in the evaporative ratio. However, 37% of the basins will still deviate from their Budyko curve trajectories, with less evaporation than expected by the framework. We elaborate on how land-use change, vegetation changes, or shifts in precipitation or snow to rain ratios can explain these deviations.

Despite its importance in sales, listening is an overlooked concept in research with limited empirical studies examining the construct since the work conducted by Castleberry and Shepherd (1993) and Ramsey and Sohi (1997) . Knowledge of the role listening plays in sales and the processes involved in explaining listening in relationship performance is limited with many discrepancies identified between studies. Using meta-analytical techniques, this study summarizes approximately 20 years of research on salesperson listening. The study developed a meta-analytical model based on the marketing and psychology literature to build an underlying framework for listening theory, advance research in listening, and provide theoretical and managerial implications. The obtained results show that customer-oriented salespeople express their care toward customers through listening, which helps them adapt their selling behaviors to fit customers' demands. Salesperson relational and sales outcomes are driven by listening through direct and mediated mechanisms.

El objetivo de este estudio fue describir y analizar el proceso de certificación de muerte y nacimiento de un hospital docente en Bogotá en el año 2014, tanto en términos de flujo de información como de calidad de la causa de muerte asignada. Se diseñó una metodología para monitorear la calidad y cobertura de las estadísticas de nacimientos y muertes hospitalarias. Durante su práctica de salud pública, diecisiete estudiantes de noveno semestre de Medicina participaron en la recopilación de información sobre 511 registros clínicos de muertes no fetales, excluyendo las muertes por una causa externa que ocurrieron en 2014 (58 % de todas las muertes no fetales ocurridas en el hospital ese año). Los estudiantes, previamente entrenados, completaron los certificados de defunción, supervisados ​​por profesores de diferentes especialidades, de acuerdo con el diagnóstico, mediante el acceso a los registros médicos de los fallecidos. La causa básica de muerte asignada después de la revisión se comparó con la causa básica originalmente certificada por médicos del hospital, en el sistema de registro en línea en uso en Colombia: RUAF-ND. Se estimó el acuerdo en la identificación de la causa básica de muerte. Se obtuvo una concordancia bruta del 80 % y un acuerdo de Kappa entre el 57 % y el 95 %, todos superiores, estadísticamente, a cero, al agrupar las causas básicas de muerte por capítulos de la CIE10, con un 6 % de códigos inutilizables en las dos bases. Este estudio podría ser replicado en otros hospitales universitarios y así fortalecer la capacitación de estudiantes de medicina en estadísticas vitales mientras se monitorea la calidad del registro de nacimientos y muertes en hospitales docentes.

Impression management tactics have recently been identified as effective strategies for coping with work stressors. However, despite the evidence that using a combination of tactics can provide more favorable outcomes than using a single tactic, previous studies have often examined impression management tactics in isolation. Furthermore, many sales organizations view their employees' proactive behaviors as essential for gaining a competitive advantage, but our knowledge about the antecedents of proactivity at work is still limited. To address this knowledge gap, we introduce a theoretical model that explains the joint moderating effects of combining two forms of impression management tactics on the relationship between work-family conflict and salespeople's proactive behaviors. We study 249 salesperson-supervisor dyads, and the results indicate that work-family conflict is negatively related to salespeople's proactive behaviors through emotional exhaustion. In addition, the combination of ingratiation and self-promotion has a buffering effect on the relationship between work-family conflict and emotional exhaustion.
