Operational Capabilities: The Secret Ingredient

We develop a theoretical definition of operational capabilities, based on the strategic management and operations management literature, and differentiate this construct from the related constructs of resources and operational practices, drawing upon the resourcebased view of the firm as our foundation. We illustrate the key features of operational capabilities using the illustration of a restaurant kitchen. Because the traits of operational capabilities are distinct, they create a barrier to imitation, making them a potential source of competitive advantage. However, operational capabilities are particularly challenging to measure, because they emerge gradually and are tacit, embedded, and manifested differently across firms. In solving this measurement conundrum, we draw upon similar situations experienced by Schein (2004) and Eisenhardt and Martin (2000) in operationalizing organizational culture and dynamic capabilities. A taxonomy of six emergent operational capabilities is developed: operational improvement, operational innovation, operational customization, operational cooperation, operational responsiveness, and operational reconfiguration. A set of measurement scales is developed, in order to measure each of the operational capabilities, and validated using two different datasets. This allows replication of the psychometric properties of the multi-item scales and helps to ensure the validity of the resulting measures

Adaptive Backstepping Controller Design for Stochastic Jump Systems

In this technical note, we improve the results in a paper by Shi et al., in which problems of stochastic stability and sliding mode control for a class of linear continuous-time systems with stochastic jumps were considered. However, the system considered is switching stochastically between different subsystems, the dynamics of the jump system can not stay on each sliding surface of subsystems forever, therefore, it is difficult to determine whether the closed-loop system is stochastically stable. In this technical note, the backstepping techniques are adopted to overcome the problem in a paper by Shi et al.. The resulting closed-loop system is bounded in probability. It has been shown that the adaptive control problem for the Markovian jump systems is solvable if a set of coupled linear matrix inequalities (LMIs) have solutions. A numerical example is given to show the potential of the proposed techniques

The Relationship Between Information and Communication Technologies and the Delivery of Public Health: A Country-level Study

We empirically investigate the relationship between information and communication technologies (ICTs) and the delivery of country-level public health. Our underlying hypothesis is that ICTs can improve the efficiency and effectiveness of public health delivery mechanisms. In our framework, we include the ICT factors of accessibility, quality, affordability, applications, and institutional efficiency and sustainability. The public health delivery is represented by the changes in the indicators of immunization coverage, TB infection, sanitation, undernourishment, life expectancy, mortality rate, and health care expenses. Results indicate in most cases ICT factors have a significant correlation to a country’s delivery of public health over and above a country’s income level. The “Accessibility” ICT factor contributes to improved delivery for nearly all of the public health indicators. This is followed by “ICT Applications.” Increased ICTs usage leads to increased health care expenditure. Our findings are useful at the country level for informing policy decisions regarding the nature and extent of investment in ICT infrastructure for the delivery of public health. We do caution that merely investing in more ICTs does not imply an automatic improvement in public health. Rather, ICTs have the potential to improve the delivery process

The Relationship Between Information and Communication Technologies and Country Governance: An Exploratory Study

In this exploratory study we investigate the relationship between information and communication technologies (ICTs) and country-level governance. We include in our framework the five factors of ICTs: access, quality, affordability, applications and institutional efficiency & sustainability. Governance indicators include voice and accountability, political stability and absence of violence, government effectiveness, regulatory quality, rule of law, and control of corruption. Using secondary data on ICTs and governance indicators for countries from the World Bank, and controlling for the wealth effect, our main multivariate result indicates that ICTs—with the exception of the institutional efficiency and sustainability factor—have a positive relationship with governance indicators. ICTs therefore, have the potential to promote good governance. We also find that accessibility is the most important ICTs’ factor to enhance governance. Our results are useful in shaping policy decisions involving the nature and extent of investment in ICT infrastructure at the country level

The Role of Information and Communication Technologies in Global Sustainability: A Review

This article discusses ways in which ICTs contribute to several aspects of global sustainability. We examine how economic development, education, energy, environment, and transportation at the country level benefit from ICTs, along with several orders of effects on global sustainability. We also examine rebound effects. The anecdotal and theoretical research suggests that the impact of ICTs is felt primarily in sustainable development. We thus identify the key challenges to be addressed in bringing about an ICTs-based sustainable world. Studying the macro impacts of ICT investments can also guide countries in setting policy and making selective investments in ICTs that will promote global sustainability
