Human resource management and developing proactive environmental strategies: The influence of environmental training and organizational learning

The need to implement advanced approaches to protect the environment is forcing companies to refocus their internal procedures and actions. To match employees' capabilities and the organization itself to these new requirements, the human resource management department can offer some key tools. This article analyzes whether environmental training (ET) and organizational learning (OL) positively influence the development of proactive environmental strategies (PESs) and compares the two processes, which differ in the time, costs, and difficulty required to implement them. Companies in the tourism sector are currently facing a highly dynamic environment where innovativeness is a decisive factor for achieving competitiveness. As such, we analyze whether the presence or absence of innovativeness influences the development of these two mechanisms. Using a sample of 252 tourism companies, we tested these relationships using structural equation modeling. The findings showed that (1) innovativeness is an antecedent of implementing ET and OL in the companies sampled, (2) both mechanisms promote implementing PESs, and (3) ET is equally as effective as OL for this purpose. Managers should take these findings into account when deciding which mechanism to apply when striving to achieve environmental proactivity.

Combining Formal Controls to Improve Firm Performance

Formal controls are an essential part of organizational design, and are theorized to positively influence organizational performance. Mello and Hunt ([2009] Transportation Journal, 48:20–39) were the first to suggest using formal controls to influence truck drivers' behavior. Extending the salesperson control literature, they documented an underresearched method of formal control that we term technology control, whereby firms use on‐board and communications technology to influence drivers. We build on their work by investigating the contingent effects of formal controls that influence the behavior of truck drivers and thereby influence the operational performance of firms in the U.S. motor carrier industry. Our work integrates the monitoring aspect of agency theory with the theory of operant conditioning and the theory of psychological reactance to develop a rationale for hypothesized contingent effects of formal controls on motor carriers' operational performance. We collected primary data pertaining to the controls used to influence truck drivers' behavior from a large sample of U.S. motor carrier firms. The results of our analyses using nonlinear structural equation modeling suggest a complex set of relationships between formal controls and operational performance. Our results shed light on scenarios where using technology to monitor driver behavior can result in positive and/or negative organizational outcomes.     

Turnpike property and convergence rate for an investment model with general utility functions

In this paper we aim to address two questions faced by a long-term investor with a power-type utility at high levels of wealth: one is whether the turnpike property still holds for a general utility that is not necessarily differentiable or strictly concave, the other is whether the error and the convergence rate of the turnpike property can be estimated. We give positive answers to both questions. To achieve these results, we first show that there is a classical solution to the HJB equation and give a representation of the solution in terms of the dual function of the solution to the dual HJB equation. We demonstrate the usefulness of that representation with some nontrivial examples that would be difficult to solve with the trial and error method. We then combine the dual method and the partial differential equation method to give a direct proof to the turnpike property and to estimate the error and the convergence rate of the optimal policy when the utility function is continuously differentiable and strictly concave. We finally relax the conditions of the utility function and provide some sufficient conditions that guarantee the turnpike property and the convergence rate in terms of both primal and dual utility functions.     

Testing a Structural Model of Psychological Well-Being,Leisure Negotiation,and Leisure Participation with Taiwanese College Students

A theoretically constructed model combining psychological well-being, negotiation, and participation was tested using structural equation modeling on Taiwanese college students (N = 464). The results provided partial support for the proposed model in that the autonomy and self-acceptance dimensions of psychological well-being had significant positive effects on negotiation strategies. However, contrary to predictions, the personal growth and purpose in life dimensions had significant negative effects on college students’ use of negotiation strategies. Developing a psychological profile of successful negotiation among college students using this framework may aid in predicting who will activate their negotiation efforts, and thus enhance the effectiveness of interventions for health promotion.     

From mode choice to modal diversion: A new behavioural paradigm and an application to the study of the demand for innovative transport services

We analyse past research efforts that focus on modal diversion in the transport sector, as opposed to the classical mode choice concept, showing the added value of this alternative framework that emerges from the existing scientific literature. The modal diversion paradigm is then used to assess the relative importance of the technical performances of transport services on one hand and of the subjective factors of its potential users on the other, when forecasting the use of a new means among a group of white-collars working in a French research institute. We quantitatively show that multimodal habits and cognitive attitudes have an importance that is in general not negligible for this group, compared to that of the transport services performances, even if only these latter are routinely considered by engineers and planners. Beyond this, we find that the role of self-related factors further increased when the group was less familiar with the technological background and the subsequent operation of the new system, such as in the case of demand responsive transport services.     

Knowledge absorptive capacity: New insights for its conceptualization and measurement

The processes for absorbing external knowledge become an essential element for innovation in firms and in adapting to changes in the competitive environment. Despite the huge growth in the absorptive capacity literature, a methodological gap still remains about a certain ambiguity in the definition of the construct specifying its theoretical domain and dimensionalization, and a lack of validation of the construct in most studies. The aim of this paper is to contribute to the literature on absorptive capacity through the creation and validation of two scales, justified with a thorough analysis of the literature, to measure the key components of the absorptive capacity construct: potential and realized absorptive capacities. The study includes confirmatory factor analysis on a sample of 952 Spanish firms to verify that the scales meet the psychometric properties the literature requires. The study results confirm the validity of the proposed scales and support their consolidation as a commonly used instrument with which to measure absorptive capacity.     

Store-, Market-, and Consumer-Characteristics: The Drivers of Store Performance

Four factors have traditionally been identified in influencing store performance: store-, market-, and consumer characteristics and competition. Given partially conflicting and, in some cases, dated findings in the literature we want to re-assess the effects. In particular, past research has usually considered only two out of the four constructs at any time, which is likely to result in erroneous interpretation of results. We draw upon a unique cross-sectional sample of grocery stores with a wide array of store characteristic, store performance, trade area, and consumer demographic variables. Using structural modeling, our prime interest is to assess the differential impact of store attractiveness, market potential, and socio-economic status on two different store performance measures, while controlling for competitive effects. We find that the market potential of a store is by far the most important driver of store sales performance and sales productivity performance. With one exception, the model and the data support the hypothesized relationships about the direction and the strength of the impact of a store's attractiveness, market potential and socio-economic characteristics of the trade area on a store's performance.

Firm growth,adaptive capability,and entrepreneurial orientation

Research summary: This paper posits adaptive capability as a mechanism through which a firm's prior growth influences the exhibition of future entrepreneurial action. Defined as the firm's proficiency in altering its understanding of market expectations, increased adaptive capability is a consequence of the new resource combinations that result from expanding organizational boundaries. Increased adaptive capability in turn corresponds to expansion of entrepreneurial activity, as firms increase their entrepreneurial orientation as the strategic mechanism to capitalize on their improved understanding of market conditions. We find support for our research model in a two‐study series conducted in South Korea and the United Kingdom. Managerial summary: Most would agree that entrepreneurially oriented firms—being innovative, entering new markets, and taking risk—grow faster. But how a firm becomes entrepreneurial is a complicated question. In this study, we flipped the growth relationship around and found support for growth contributing to a firm's entrepreneurial orientation. But between growth and being more entrepreneurial is the firm's ability to recognize changes in market expectations. We argue that as a firm grows, it acquires new resources and new knowledge of how to use those resources. These new resource combinations increase its ability to recognize changes in market expectations—its adaptive capability. This capability uncovers new entrepreneurial opportunities for value creation. To capture this potential value, firms expand their entrepreneurial orientation. Copyright © 2016 John Wiley & Sons, Ltd.
