In recent years, the dynamic capabilities view has attracted attention in the management literature, and theoretical papers note many research challenges. Currently, one of the most significant issues is the role of the marketing function in the development of dynamic capabilities, and some recent discussions have even introduced the new term ‘dynamic marketing capabilities’. The main area of interest is how to achieve a well‐integrated framework to serve as the starting point for empirical papers. Although the most recent research proposes a wide range of processes as possible dynamic marketing capabilities, it is difficult to find consensus among these proposals. To resolve this difficulty, this paper seeks to define the dynamic marketing capabilities construct based on accepted components in the generic dynamic capabilities view. More specifically, it defines the role of dynamic marketing capabilities through absorptive capacity and knowledge management. By identifying these components and relating them in an integrative model, the authors propose to explain how dynamic marketing capabilities work and precisely which marketing processes promote both components.  相似文献

The aim of the study was to obtain anthropometric data of adult wheelchair users at Mexico. This study count with 108 disabled people (56 men and 52 women) using the wheelchair and having the upper extremities sufficiently efficient to perform professional activities. The subjects were aged 18-60. From the measurements obtained, it can be said that in each of these measures was observed that men have larger dimensions than women, except for body depth, in which women had a slightly greater difference. When comparing the data in this study against other studies it shows that there is a significant difference between the averages of these studies. Similar results were obtained when comparing our data against data of standard population. Anthropometric data obtained through this study appear to be the only of this kind in Mexico and showed significant differences between measures of disabled persons and standard persons. the use of these data may be helpful for the proper design of workstations designed for use by adults who use.  相似文献

Despite the practical importance of Personal Protective Equipment (PPE), both in production and in consumption, it is observed a main problem regarding the quality of many PPE?s used in Brazil. This study found a gap between the state of the art and the state of prevailing practices in the design of PPE?s, which main consequences affect the health of workers who use PPE in agriculture activities. The results of this study identified legal constraints of this occurrence, involving the validation of PPE designed for isolate agents, without the analysis of relevant activities and without prototypes experiments in more frequent use situation.  相似文献

Resumen

El miedo, como una de las consecuencias de la situación sociopolítica de Argentina en los últimos años, ha afectado, y sigue afectando, a la mayor parte de los miembros de esa sociedad, presentando características diferentes según el periodo considerado, es decir, dictadura, transición a la democracia o gobierno democrático concreto. Se discuten sus implicaciones para la sociedad y se sugieren algunas formas de afrontarlo.  相似文献

Most real‐life decisions are made with less than perfect information and there is often some opportunity to acquire additional information to increase the quality of the decision. In this article, we define and study the sequential information acquisition process of a rational decision maker (DM) when allowed to acquire any finite amount of information from a set of products defined by vectors of characteristics. The information acquisition process of the DM depends both on the values of the characteristics observed previously and the number and potential realizations of the remaining characteristics. Each time an observation is acquired, the DM modifies the probability of improving upon the products already observed with the number of observations available. We construct two real‐valued functions whose crossing points determine the decision of how to allocate each available piece of information. We provide several numerical simulations to illustrate the information acquisition incentives defining the behavior of the DM. Applications to knowledge management and decision support systems follow immediately from our results, particularly when considering the introduction and acceptance of new technological products and when formalizing online search environments.  相似文献

On beta regression residuals   总被引:1,自引:0,他引:1  
We propose two new residuals for the class of beta regression models, and numerically evaluate their behaviour relative to the residuals proposed by Ferrari and Cribari-Neto. Monte Carlo simulation results and empirical applications using real and simulated data are provided. The results favour one of the residuals we propose.  相似文献

This paper presents an algorithm to obtain near optimal solutions for the Steiner tree problem in graphs. It is based on a Lagrangian relaxation of a multi-commodity flow formulation of the problem. An extension of the subgradient algorithm, the volume algorithm, has been used to obtain lower bounds and to estimate primal solutions. It was possible to solve several difficult instances from the literature to proven optimality without branching. Computational results are reported for problems drawn from the SteinLib library.  相似文献
