Building top management muscle in a slow growth environment: How different is better at Greyhound Financial Corporation

The turbulence experienced in the 1980s in the U.S. business environment has led to something of a motivational crisis among corporate managers. Increased competition, budget constraints, and changing demographics are forcing companies into adopting strategies geared toward downsizing and flatter organizational structures. While corporate America probably has begun to accept its leaner profile, it has not yet successfully addressed the issue of how to keep the best managerial talent tuned in and turned on in an era of dwindling resources. This article describes and assesses one corporation\u27s efforts to maintain top-managerial motivation through a unique form of job swapping called the Muscle Building program at Greyhound Financial Corporation in Phoenix, Arizona. Muscle building. a top-management job rotation program, helps prevent career gridlock, fosters management diversity, and provides for top-management succession. Hidden costs and benefits of the program and issues concerning its implementation are discussed

Borgs in the Org? Organizational Decision Making and Technology

Data warehousing and the development of the World Wide Web both augment information gathering (search) processes in individual decision making by increasing the availability of required information. Imagine, for example, that one wanted to buy new golf clubs. Thirty years ago, the cost of information gathering would likely have limited an individual\u27s search process to geographically proximal vendors and the golf clubs they stocked. Today, a prospective purchaser can log onto the World Wide Web to find out what types of golf clubs are available anywhere; consult databases, chat rooms, and bulletin boards (e.g., epinions.com) to gather product information and user opinions; and compare prices across vendors around the world

Anti-Circumvention: Has Technology\u27s Child Turned Against Its Mother?

Because its function is to protect and support innovation, copyright has been deemed a child of technology. Yet, as copyright laws increase the scope of protection for copyrighted material, one may wonder when such protection will begin to stymie, rather than encourage, emerging technology. The global trend toward internationalizing copyright protection has resulted in the World Intellectual Property Organization (WIPO) Copyright Treaty, which was intended, in part, to bring international copyright protection into the digital age. The treaty, however, extends traditional copyright protections by including a requirement that member nations implement anti-circumvention provisions into their laws. Great debate has emerged about whether anti-circumvention provisions are a permissible extension of traditional copyright law. This Note considers some of the primary criticisms of anti-circumvention laws and the dangers inherent in an overly broad interpretation of Article 11 of the WIPO Copyright Treaty on anti-circumvention. Indeed, this Note argues that instead of encouraging creativity and the production of technology, overly broad anti-circumvention provisions have thwarted research into and development of advancing technologies. As a result, this Note considers how the goals of the WIPO and its Copyright Treaty could be achieved and concludes that anti-circumvention provisions would be more effective if limited by narrow interpretation or reasoned exceptions

Leaving Nothing to Chance: Modeling the Proactive Structuration of a New Technology

Adaptive structuration theory (AST, DeSanctis and Poole 1994) describes how people come to understand and use a technology. In this paper we develop the idea of proactive structuration--how social networking can be proactively managed in order to speed the comprehensive adaptation of a technology within a community of users. We examine two facets of proactive structuration--formal institutionalization of a community of practice and socialization of users--and stochastically model the impact of proactive structuration on comprehensive adaptation latency. Implications for the effective management of new technology adoption are discussed.

Promises, pitfalls, and paradox: Cognitive elements in the implementation of new technology

Offers a model of new technology implementation (NTI) that elaborates the role of cognitions, specifically user and implementer frames in NTI. The model reveals the paradox of value (PV) and the paradox of experience (PE). The PV occurs when the divergence between user frames (the balanced information that users need) and implementer frames (the unbalanced information that implementers provide) creates negative surprises for users when they experience a new technology. The PE is that these negative surprises need not be costly and may be key components of successful implementation. The key proposition is that the pitfall of unbalanced implementation frames and the PV and PE may be turned into promises of successful implementation. Managers must prepare and accept the costs of the users learning to become experts. Managers wanting to apply this philosophy to their NTI need only to challenge their users with the technology

Adaptive evolution of centromere proteins in plants and animals

BACKGROUND: Centromeres represent the last frontiers of plant and animal genomics. Although they perform a conserved function in chromosome segregation, centromeres are typically composed of repetitive satellite sequences that are rapidly evolving. The nucleosomes of centromeres are characterized by a special H3-like histone (CenH3), which evolves rapidly and adaptively in Drosophila and Arabidopsis. Most plant, animal and fungal centromeres also bind a large protein, centromere protein C (CENP-C), that is characterized by a single 24 amino-acid motif (CENPC motif). RESULTS: Whereas we find no evidence that mammalian CenH3 (CENP-A) has been evolving adaptively, mammalian CENP-C proteins contain adaptively evolving regions that overlap with regions of DNA-binding activity. In plants we find that CENP-C proteins have complex duplicated regions, with conserved amino and carboxyl termini that are dissimilar in sequence to their counterparts in animals and fungi. Comparisons of Cenpc genes from Arabidopsis species and from grasses revealed multiple regions that are under positive selection, including duplicated exons in some grasses. In contrast to plants and animals, yeast CENP-C (Mif2p) is under negative selection. CONCLUSIONS: CENP-Cs in all plant and animal lineages examined have regions that are rapidly and adaptively evolving. To explain these remarkable evolutionary features for a single-copy gene that is needed at every mitosis, we propose that CENP-Cs, like some CenH3s, suppress meiotic drive of centromeres during female meiosis. This process can account for the rapid evolution and the complexity of centromeric DNA in plants and animals as compared to fungi

Reaching for the Moon: Expanding transactive memory\u27s reach with wikis and tagging

Transactive memory systems (TMS) support knowledge sharing and coordination in groups. TMS are enabled by the encoding, storage, retrieval, and communication of knowledge by domain experts-knowing who knows what. The NASA Ames Intelligent Robotics Group provides an example of how TMS theoretical boundaries are stretched in actual use. This group is characterized as being highly innovative as they routinely engage in field studies that are inherently difficult due to time and technology resource constraints. We provide an expanded view of TMS that includes the technology support system available to this group, and possible further extensions to NASA\u27s or other such dynamic groups\u27 practice

Virtual study groups: A challenging centerpiece for working adult management education

Groups and teams are critical to modern organizations, and consequently management education has incorporated groups as a centerpiece of both content (the study of group process) and process (the use of study groups and group projects). Unfortunately, working-adult educational programs appear to have yet to take an important final step - acknowledging that study groups often interact virtually and then providing support for virtual study group interaction. We provide both theory and data concerning the use of study groups as virtual teams. We believe that there are important benefits to be gained when study groups make educated decisions about the design and process of their virtual interaction

Adapting Urban Water Systems to Manage Scarcity in the 21st Century: The Case of Los Angeles.

Acute water shortages for large metropolitan regions are likely to become more frequent as climate changes impact historic precipitation levels and urban population grows. California and Los Angeles County have just experienced a severe four year drought followed by a year of high precipitation, and likely drought conditions again in Southern California. We show how the embedded preferences for distant sources, and their local manifestations, have created and/or exacerbated fluctuations in local water availability and suboptimal management. As a socio technical system, water management in the Los Angeles metropolitan region has created a kind of scarcity lock-in in years of low rainfall. We come to this through a decade of coupled research examining landscapes and water use, the development of the complex institutional water management infrastructure, hydrology and a systems network model. Such integrated research is a model for other regions to unpack and understand the actual water resources of a metropolitan region, how it is managed and potential ability to become more water self reliant if the institutions collaborate and manage the resource both parsimoniously, but also in an integrated and conjunctive manner. The Los Angeles County metropolitan region, we find, could transition to a nearly water self sufficient system

Differential rates of perinatal maturation of human primary and nonprimary auditory cortex

Abstract Primary and nonprimary cerebral cortex mature along different timescales; however, the differences between the rates of maturation of primary and nonprimary cortex are unclear. Cortical maturation can be measured through changes in tissue microstructure detectable by diffusion magnetic resonance imaging (MRI). In this study, diffusion tensor imaging (DTI) was used to characterize the maturation of Heschl’s gyrus (HG), which contains both primary auditory cortex (pAC) and nonprimary auditory cortex (nAC), in 90 preterm infants between 26 and 42 weeks postmenstrual age (PMA). The preterm infants were in different acoustical environments during their hospitalization: 46 in open ward beds and 44 in single rooms. A control group consisted of 15 term-born infants. Diffusion parameters revealed that (1) changes in cortical microstructure that accompany cortical maturation had largely already occurred in pAC by 28 weeks PMA, and (2) rapid changes were taking place in nAC between 26 and 42 weeks PMA. At term equivalent PMA, diffusion parameters for auditory cortex were different between preterm infants and term control infants, reflecting either delayed maturation or injury. No effect of room type was observed. For the preterm group, disturbed maturation of nonprimary (but not primary) auditory cortex was associated with poorer language performance at age two years
