Unraveling the complexity of the organizational adoption of electronic procurement: a direction for future research
No full textThis paper describes directions for future research to study the organizational adoption of electronic procurement (EP). An extensive exploratory study of EP adoption is taken as a starting point. In this study issues were identified that influence individual level adoption across different roles and phases in an organizational change process. An extension is proposed to this exploration of issues in order to develop insights in the way that management can effectively intervene in the organizational adoption process of EP. Specific topics that are addressed in this\u3cbr/\u3eextension are the derivation of interventions from issues, dealing with roles, change phases, the link between individual and organizational level, different EP types and industries. Finally, some closing remarks are made
Coping with individuals' resistance to change
No full textProbably every purchasing manager is familiar with the employee who just won't change. Sametimes it is easy to understand why: the employee might fear losing his or her job, notwant to learn new skills or notlook forward to join a new team. On most other occasions employee resistance is more difficult to understand. This chapter deals with the effects of individual behaviour on strategie change processes and how change leaders can anticipate or react to this. The impartanee of individual behaviour in such processes was already briefly mentioned in Chapter 2. Individual purchasers or buyers can play an active role in realizing change, a passive role or even actively resist change. The latter will be even more strongly demonstrated in Chapter 11 and- tosome extent- in Chapter 12. A better understanding of possible individual reactions to a change initiative, and the
underlying reasons, may help the change leader to better manage the process. The
purpose of this chapter is therefore to explore the effect of individual behaviour on the process of strategie change and to derive some lessans for rnanaging individual behaviour. The different concepts that are introduced in this chapter will be illustrated by the TradeRanger case. This case describes how a number of companies in the oii and chemieals industry developed and implemented an e-procurement tool
Decline in terrestrial moisture sources of the mississippi river basin in a future climate
No full textAssessment of the impact of climate change on water resources over land requires knowledge on the origin of the precipitation and changes therein toward the future. We determine the origin of precipitation over the Mississippi River basin (MRB) using high-resolution (~25 km) climate model simulations for present and future climate (RCP4.5). Moisture resulting in precipitation over the MRB is tracked back in time using Eulerian offline moisture tracking, in order to find out from where this water originally evaporated (i.e., the moisture sources). We find that the most important continental moisture sources are the MRB itself and the area southwest of the basin. The two most relevant oceanic sources are the Gulf of Mexico/Caribbean and the Pacific. The distribution of sources varies per season, with more recycling of moisture within the basin during summer and more transport of moisture from the ocean toward the basin in winter. In future winters, we find an increase in moisture source from the oceans (related to higher sea surface temperatures), resulting in more precipitation over the MRB. In future summers, we find an approximately 5% decrease in moisture source from the basin itself, while the decrease in precipitation is smaller (i.e., lower recycling ratios). The results here are based on one climate model, and we do not study low-frequency climate variability. We conclude that Mis-sissippi’s moisture sources will become less local in a future climate, with more water originating from the oceans.Water Resource
Socio-hydrologic modeling to understand and mediate the competition for water between agriculture development and environmental health: Murrumbidgee River Basin, Australia (discussion paper)
No full textCompetition for water between humans and ecosystems is set to become a flash point in the coming decades in many parts of the world. An entirely new and comprehensive quantitative framework is needed to establish a holistic understanding of that competition, thereby enabling the development of effective mediation strategies. This paper presents a modeling study centered on the Murrumbidgee River Basin (MRB). The MRB has witnessed a unique system dynamics over the last 100 years as a result of interactions between patterns of water management and climate driven hydrological variability. Data analysis has revealed a pendulum swing between agricultural development and restoration of environmental health and ecosystem services over different stages of basin scale water resource development. A parsimonious, stylized, quasidistributed coupled socio-hydrologic system model that simulates the two-way coupling between human and hydrological systems of the MRB is used to mimic dominant features of the pendulum swing. The model consists of coupled nonlinear ordinary differential equations that describe the interaction between five state variables that govern the co-evolution: reservoir storage, irrigated area, human population, ecosystem health, and a measure of environmental awareness. The model simulations track the propagation of the external climatic and socio-economic drivers through this coupled, complex system to the emergence of the pendulum swing. The model results point to a competition between human “productive” and environmental “restorative” forces that underpin the pendulum swing. Both the forces are endogenous, i.e., generated by the system dynamics in response to external drivers and mediated by humans through technology change and environmental awareness, respectively. We propose this as a generalizable modeling framework for coupled human hydrological systems that is potentially transferable to systems in different climatic and socio-economic settings.Water ManagementCivil Engineering and Geoscience
