Abstract
The monitoring of respirable particulate matter (PM10) and of total carbon percentage (mass basis) in the atmosphere of São Carlos (SP) was performed in the period between September 1997 and January 2000. São Carlos, located in the central region of the state of São Paulo, has a population of close to 180,000 inhabitants and about 500 industrial establishments of medium to small size, mainly dealing with metallurgy, textiles, food and ceramics. The equipment used for air monitoring was a high volume sampler (GVS‐GRASEBY/GMW) equipped with a one‐stage inertial separator for a 10μm particle cut diameter. The PM10 concentration was determined by gravimetry and the total carbon concentration by the Ströheim method. The results show a well defined seasonal dependence of both the PM10 and of the total carbon concentration. Higher concentrations of PM10 and carbon were observed in autumn and winter, which also coincided with low relative humidity and precipitation. The measured trends were compared with the PM10 data from the city of São Paulo in the same period and showed similar seasonal dependence. However, in relative terms, the PM10 concentration in São Carlos showed stronger seasonal dependence than in São Paulo.

Abstract
Purpose
There has been a growing concern about air quality because in recent years, industrial and vehicle emissions have resulted in unsatisfactory human health conditions. There is an urgent need for the measurements and estimations of particulate pollutants levels, especially in urban areas. As a contribution to this issue, the purpose of this paper is to use data from measured concentrations of particulate matter and meteorological conditions for the predictions of PM10.
Design/methodology/approach
The procedure included daily data collection of current PM10 concentrations for the city of São Carlos-SP, Brazil. These data series enabled to use an estimator based on artificial neural networks. Data sets were collected using the high-volume sampler equipment (VFA-MP10) in the period ranging from 1997 to 2006 and from 2014 to 2015. The predictive models were created using statistics from meteorological data. The models were developed using two neural network architectures, namely, perceptron multilayer (MLP) and non-linear autoregressive exogenous (NARX) inputs network.
Findings
It was observed that, over time, there was a decrease in the PM10 concentration rates. This is due to the implementation of more strict environmental laws and the development of less polluting technologies. The model NARX that used as input layer the climatic variables and the PM10 of the previous day presented the highest average absolute error. However, the NARX model presented the fastest convergence compared with the MLP network.
Originality/value
The presentation of a given PM10 concentration of the previous day improved the performance of the predictive models. This paper brings contributions with the NARX model applications.

Abstract
Purpose
The purpose of this paper is to develop a nuanced framework for evaluating a channel partner’s performance in distribution channel relationships. Given a channel partner’s task environment characteristics (high/low munificence, dynamism and complexity), the study examines which performance metrics (output, activity or capability) are most relevant for evaluating its performance levels effectively.
Design/methodology/approach
The study adopts self-administered cross-sectional survey-based research design. Matched data were collected from 252 channel partners – manager relationship dyads. The latent change score (LCS) model within SEM framework provides mean paired-differences of the relevance ratings for each metrics. This was used to assess the empirical validity of the hypothesized relationships.
Findings
The study demonstrates the importance of calibrating performance evaluation metrics to a channel partner’s task environment state, made possible by its holistic approach to performance evaluation. Based on an extensive analysis, it shows that no single metric is relevant within all environmental states; rather, it could be dysfunctional, a result that differs from vast majority of the literature.
Research limitations/implications
Investigates individual linkages between task environment dimensions and performance metrics to provide a fuller understanding of these relationships. Also provides a theoretical framework to support further research on the topic.
Practical implications
The study provides managerial guidelines (and extensive graphical analysis) for nuanced and dynamic evaluation of channel partners’ performance that can enable firms to identify and promote their most valuable channel partners and prevent the deterioration of others.
Originality/value
First one to develop and empirically validate a nuanced framework for evaluating performance of exchange partners that operate under diverse task environment states.

Abstract
Purpose
This study aims to address the question of why managers make different decisions in employee downsizing when their firms face external threats. Our research intends to shed light on whether and how CEOs' cognition (motivational attributes associated with regulatory focus) influences their decision-making and firms’ strategic actions on downsizing under high resource scarcity in the industry environment.
Design/methodology/approach
We used a longitudinal panel of 5,544 firm-year observations of US firms from 2003 to 2015 to test our conceptual model. The data was obtained from various sources, including corporate earnings call transcripts and archival databases. We used panel logistic regressions with both fixed and random effects in our research design.
Findings
Our results suggest that CEOs' motivational attributes could influence their employee downsizing decisions in response to external threats. We find that CEOs who are more promotion-focused (a stronger drive towards achieving ideals) are less likely to lay off employees during high resource scarcity. Conversely, CEOs with a higher prevention focus (a greater concern for security) do not have a meaningful impact on employee downsizing during periods of external resource scarcity.
Originality/value
Previous research has argued that a significant external threat would diminish individuals' impact on firm strategies and outcomes. Our findings challenge this idea, indicating that CEOs with a stronger drive towards achieving ideals are less inclined to lay off employees when resources are scarce in the environment. This study contributes to behavioral strategy research by providing new insights into how upper echelons’ cognition can influence their decision-making and firms’ employee downsizing.

Abstract
Purpose
This paper presents an overview of Latin American (LA) publications on corporate social responsibility (CSR) and closely related themes that appear in ISI Thompson Reuters Social Science Citation Index journals, in the period 2000-2017. The purpose of this paper is twofold. The first is to understand the institutional context in which this research is being produced, and to reflect on how it can be improved. The second is to map out key research strands in this literature, to discuss its achievements and limitations, and identify opportunities for future research.
Design/methodology/approach
A quantitative-qualitative systematic review was performed using a standard bibliometric approach. A total of 148 articles from 36 journals, indexed in the ISI Thompson Reuters Social Science Citation Index, were selected and analyzed. A systematic analysis was performed, based on a review protocol, which comprised following eight steps: research objectives, article search, articles selection, article identification, root themes coding, data coding, data coding validation and content analysis.
Findings
Research about CSR Latin America features a very low citation record. It is also very fragmented. Both of these characteristics reflect little conversation amongst scholars publishing on this topic in indexed venues. More generally, participation in these venues reflects the location of scholars working on this topic as peripheral actors in scholarly conversations. The study identifies many opportunities for future research that attend to key issues that are relevant for Latin America and that will stimulate a more dynamic conversation among scholars interested in the region.
Research limitations/implications
First, this study is limited to articles on CSR research on LA published in ISI journals. It does not show the whole trend of other academic and managerial publications in the region. Second, although the articles selected were retrieved based on 17 search terms derived from the theoretical framework, the complexity of CSR-related themes and its evolution could have caused some terms, and therefore publications, to be left out.
Practical implications
Results provide scholars interested in the region with updated information about the state of research on the topic and about opportunities for future research. They also provide business schools in the region with a valuable input for a comprehensive reflection on research policy.
Social implications
In the 30th anniversary of Academia (Revista Latinoamericana de Administración), this study offers recommendations on how research on CRS in Latin America could be made more visible and relevant.
Originality/value
This is the first bibliometric analysis of scholarly publications on CSR and related issues in Latin America. It is also unique in addressing institutional factors that may be conditioning intellectual production on the topic.
Propósito
Este artículo presenta una descripción general de las publicaciones sobre América Latina (AL) acerca de la Responsabilidad Social Empresarial (RSE) y temas estrechamente relacionados que aparecen en las revistas del Índice ISI Thompson Reuters de Ciencias Sociales, en el período 2000-2017. El propósito de este estudio es doble. El primero es comprender el contexto institucional en el que se está produciendo esta investigación, y reflexionar sobre cómo se puede mejorar dicho contexto. El segundo es trazar líneas de investigación clave en esta literatura, para discutir sus logros y limitaciones, e identificar oportunidades para futuras investigaciones.
Metodología
Se realizó una revisión sistemática cualitativa-cuantitativa utilizando un enfoque bibliométrico estándar. Se seleccionaron y analizaron un total de 148 artículos de 36 revistas indexadas en el Índice de citas de Ciencias Sociales de ISI Thompson Reuters. Se realizó un análisis sistemático, basado en un protocolo de revisión que comprendía ocho pasos: objetivos de la investigación, búsqueda de artículos, selección de artículos, identificación de artículos, codificación de temas raíz, codificación de datos, validación de codificación de datos y análisis de contenido.
Recomendaciones
Las publicaciones sobre RSE en AL presentan un registro de citas muy bajo, además de muy fragmentado. Ambas características reflejan poca conversación entre los académicos que publican sobre este tema en revistas indexadas. En términos más generales, la participación en estas publicaciones refleja la ubicación de los académicos que trabajan en este tema como actores periféricos en las conversaciones académicas. El estudio identifica muchas oportunidades para futuras investigaciones que atienden temas clave que son relevantes para AL y que estimularán una conversación más dinámica entre los académicos interesados en la región.
Limitaciones
En primer lugar, este estudio se limita a artículos sobre investigación de RSE en AL publicados en revistas ISI. No muestra la tendencia general de otro tipo de publicaciones académicas y gerenciales sobre la región. En segundo lugar, aunque la búsqueda en esta investigación se hizo con base en 17 términos derivados del marco teórico, la complejidad de los temas relacionados con la RSE y su evolución podrían haber ocasionado que algunos términos, y por lo tanto publicaciones, hayan quedado fuera del análisis.
Implicaciones prácticas
Los resultados proporcionan a los estudiosos interesados en la región información actualizada sobre el estado de la investigación sobre el tema y sobre las oportunidades para investigaciones futuras. También le ofrecen a las escuelas de negocios de la región un aporte valioso para una reflexión integral sobre la política de investigación.
Implicaciones sociales
En el 30 aniversario de Academia (Revista Latinoamericana de Administración), este estudio ofrece recomendaciones sobre cómo la investigación sobre RSE en AL podría hacerse más visible y relevante.
Originalidad
Este es el primer análisis bibliométrico de publicaciones académicas sobre RSE y temas relacionados en AL. También es único al abordar los factores institucionales que pueden condicionar la producción intelectual sobre el tema.

Abstract
Purpose
The purpose of this paper is to develop a conceptual framework for performance evaluation of channel partners in distribution relationships and develop a scale to measure the proposed dimensions of performance.
Design/methodology/approach
The proposed framework is built on the theoretical foundations of salesforce control systems and organizational performance. The authors developed the measurement scale by the three-stage protocol and established the scale’s reliability, factor structure and validity through the data collected from 252 firm-channel partner dyads across automobile firms in India.
Findings
The proposed framework highlights three distinct dimensions of channel partners’ performance, i.e. output performance, the financial/other objective results; activity performance, the activities, behavior and process-compliance levels; and capability performance, the resources and capabilities of channel partners. An 18-item measurement scale is developed to measure the three proposed dimensions of channel partners’ performance.
Research limitations/implications
The proposed framework conceptualizes the three key dimensions of channel partners’ performance that can assist firms in exercising a focussed approach to performance management in distribution channel relationships and other inter-firm contexts. This study contributes to the legitimacy and further development of research in the area.
Practical implications
The measurement scale provides valid and reliable items for a rigorous performance analyses of channel partners, both at the individual level as well as at the level of the distribution channel as a whole. These performance analyses have multiple applications, right from managing the day-to-day channel activities to steering the channel strategy.
Originality/value
The paper presents a multidimensional conceptual framework for performance evaluation of channel partners and provides a suitable instrument for operationalizing future empirical research in the area.

Abstract
This chapter adopts the midrange theories schema to expand Pels and Sheth (2017) matrix on business models to serve the low-income consumers (LIC): market adaptation, mission focus, radical innovation, and inclusive ecosystems. To this end, it identifies the underlying general business theories (systems theory and neo-classical economics) and ontological theories (positivism and interpretivist) nested in each of the matrix’s four cells.
Understanding the general theories from which concepts and guidelines are drawn allows a two-way contribution. On one hand, it comprehends which other concepts can be integrated into the LIC literature. Alternatively, it highlights what insights generated from the study of the LIC markets bring to these theories.
