Temporal Induction of Missing Birdsong Segments in European Starlings
Authors: Braaten Richard F. , Leary Jennifer C.
Published: March 2003

Four European starlings ( Sturnus vulgaris) discriminated a 300-ms segment of starling song from a 300-ms segment of budgerigar song in three contexts in a two-choice key-peck operant discrimination task. In the starling-song context, on each trial, one of the song segments was presented in the context of starling song; in the budgerigar-song context, the segments were presented in the context of budgerigar song. In the no-song context, the song segments were presented outside of a song context. On occasional unreinforced probe trials, the song segments were replaced by either white noise or silence. On noise trials in the two song contexts, but not on silent trials in the song contexts or noise trials in the no-song context, the starlings were significantly more likely to respond to the key associated with the starling song segment than to the key associated with the budgerigar song segment. This effect was especially pronounced in the starling-song context. The results indicate that noise induces perceptual restoration of missing birdsong segments in songbirds.
Neurocognitive Performance in Alcoholics: Is Polysubstance Abuse Important?
Authors: Jo Nixon Sara
Published: March 2003

The neurocognitive effects of alcohol have been frequently examined. Studies reveal a wide array of cognitive deficits. Attempts to develop a parsimonious model for these effects have been difficult because of the intra- and intersubject variability. Complicating the development of a model of cognitive deficits in substance abusers is the common practice of polysubstance abuse. The use of theoretical models that focus on the underlying cognitive processes offers flexibility while maintaining sufficient theoretical precision. This article briefly reviews the literature on neurocognitive changes associated with substance abuse as well as the various theoretical models that have been studied. It also provides an overview of recovery of function. Its primary objective is to evaluate cognitive function among alcoholic subtypes, defined by patterns of other drug use. This analysis suggests there are significant differences in neurocognitive function among these subtypes.
Animal Cognition: The Bridge Between Animal Learning and Human Cognition
Authors: Zentall Thomas R.
Published: March 2003

Carefully controlled research with animals has demonstrated cognitive capacities for which traditional theories of associative learning cannot account. One example is the symbolic representation of stimuli. If two arbitrary stimuli are associated with a third event, an emergent relation can be shown to develop. A second example is the ability of animals to plan ahead, and to choose whether to plan ahead or not. Although animals have often been used to model drug effects in humans, these models have rarely been used to examine the effects of drugs on cognitive functioning. Furthermore, examination of the effects of drugs on the cognitive behavior of animals may help to identify the nature of the representations underlying the cognition.
Hale-Bopp and Handedness: Individual Differences in Memory for Orientation
Authors: Martin Maryanne , Jones Gregory V.
Published: March 2003

The accuracy with which a person recalls the orientation of a human figure or head has been shown to depend systematically on the person's handedness. This study investigated whether memory for the orientation of an inanimate object displays a similar effect. In contrast to previous work investigating memory for depictions encountered over many years, the present work focused on memory for a unique event that engaged considerable attention over a relatively brief period—Comet Hale-Bopp. The results showed that although right-handed and left-handed individuals did not differ in their memory for semantic information concerning the comet, they did differ in their memory for its orientation. Right-handed people were significantly more likely than left-handed people both to recall and to recognize the comet as facing to the left. The results suggest that memory performance may be influenced by patterns of underlying cerebral motor activation.
Top-Down Attentional Guidance Based on Implicit Learning of Visual Covariation
Authors: Chun Marvin M. , Jiang Yuhong
Published: March 2003

The visual environment is extremely rich and complex, producing information overload for the visual system. But the environment also embodies structure in the form of redundancies and regularities that may serve to reduce complexity. How do perceivers internalize this complex informational structure? We present new evidence of visual learning that illustrates how observers learn how objects and events covary in the visual world. This information serves to guide visual processes such as object recognition and search. Our first experiment demonstrates that search and object recognition are facilitated by learned associations (covariation) between novel visual shapes. Our second experiment shows that regularities in dynamic visual environments can also be learned to guide search behavior. In both experiments, learning occurred incidentally and the memory representations were implicit. These experiments show how top-down visual knowledge, acquired through implicit learning, constrains what to expect and guides where to attend and look.
Unitization of Sublexical Components in Implicit Memory for Novel Words
Authors: Dorfman Jennifer
Published: March 2003

This study examines the role of componential knowledge and unitization processes in implicit memory. In two experiments, subjects studied novel words formed out of morphemes, syllables, or pseudosyllables. They then completed an implicit task requiring a judgment as to which of two items (one old, one new) was a better English word. Experiment 1 replicated previous results showing priming for nonwords formed out of morphemes and syllables but not pseudosyllables. This effect was present when orthographic factors were controlled and, unlike explicit (recognition) memory, was equally strong following visual and semantic processing. Experiment 2 showed that little priming was present across a variety of conditions in which the connections between components were altered across study and test. Results are interpreted as evidence for the role of perceptually based activation and integration processes in implicit memory for novel stimuli.
Neural Correlates of Theory-of-Mind Reasoning: An Event-Related Potential Study
Authors: Sabbagh Mark A. , Taylor Marjorie
Published: March 2003

Everyday understanding of human behavior rests on having a theory of mind—the ability to relate people's actions to underlying mental states such as beliefs and desires. It has been suggested that an impaired theory of mind may lie at the heart of psychological disorders that are characterized by deficits in social understanding, such as autism. In this study, we employed the event-related potential methodology to index the activity of neural systems that are engaged during theory-of-mind reasoning in adults. Specifically, neural activity elicited by tasks that required thinking about mental as compared with nonmental representations (i.e., beliefs vs. photographs) was characterized by a focally enhanced positivity over left frontal areas, which was diminished over left parietal areas. These findings provide an important perspective on both children's theory-of-mind development and the neurobiology of disorders in which theory of mind seems to be impaired.
The Effect of Callosotomy on Novel Versus Familiar Bimanual Actions: A Neural Dissociation Between Controlled and Automatic Processes?
Authors: Franz Elizabeth A. , Waldie Karen E. , Smith Melissa J.
Published: March 2003

The corpus callosum is the large band of fibers that connects the two cerebral hemispheres of the brain. Individuals who have had the fibers of these tracts surgically severed by callosotomy are able to draw two different spatial figures simultaneously using the left and right hands, without evidence of interactions in the spatial planning processes. Paradoxically, tasks (e.g., tying shoes) that appear to depend on spatial interactions between the left and right hands, each of which is controlled by a separate cerebral hemisphere, pose little difficulty. How can this be? In the study reported here, we observed that well-learned cooperative actions of the hands remain intact in 2 callosotomy patients, whereas actions novel to these patients are virtually impossible for them to produce without visual guidance. We infer that duplicate memory engrams of well-learned actions can be accessed by both cerebral hemispheres without callosal mediation, whereas callosal interactions are necessary for precise cross-matching of sensory information during spatial planning or perceptual-motor learning.
Using a Cognitive Architecture to Examine what Develops
Authors: Jones Gary , Ritter Frank E. , Wood David J.
Published: March 2003

Different theories of development propose alternative mechanisms by which development occurs. Cognitive architectures can be used to examine the influence of each proposed mechanism of development while keeping all other mechanisms constant. An ACT-R computational model that matched adult behavior in solving a 21-block pyramid puzzle was created. The model was modified in three ways that corresponded to mechanisms of development proposed by developmental theories. The results showed that all the modifications (two of capacity and one of strategy choice) could approximate the behavior of 7-year-old children on the task. The strategy-choice modification provided the closest match on the two central measures of task behavior (time taken per layer, r = .99, and construction attempts per layer, r = .73). Modifying cognitive architectures is a fruitful way to compare and test potential developmental mechanisms, and can therefore help in specifying “what develops.”
Age Differences in the Control of Looking Behavior: Do You Know Where Your Eyes Have Been?
Authors: Kramer Arthur F. , Hahn Sowon , Irwin David E. , Theeuwes Jan
Published: March 2003

Previous research has shown that during visual search young and old adults' eye movements are equivalently influenced by the appearance of task-irrelevant abrupt onsets. The finding of age-equivalent oculomotor capture is quite surprising in light of the abundant research suggesting that older adults exhibit poorer inhibitory control than young adults on a variety of different tasks. In the present study, we examined the hypothesis that oculomotor capture is age invariant when subjects' awareness of the appearance of task-irrelevant onsets is low, but that older adults will have more difficulty than young adults in inhibiting reflexive eye movements to task-irrelevant onsets when awareness of these objects is high. Our results were consistent with the level-of-awareness hypothesis. Young and old adults showed equivalent patterns of oculomotor capture with equiluminant onsets, but older adults misdirected their eyes to bright onsets more often than young adults did.
A Threatening Intellectual Environment: Why Females Are Susceptible to Experiencing Problem-Solving Deficits in the Presence of Males
Authors: Inzlicht Michael , Ben-Zeev Talia
Published: March 2003

Does placing females in environments in which they have contact with males cause deficits in their problem-solving performance? Is a situational cue, such as gender composition, sufficient for creating a threatening intellectual environment for females—an environment that elicits performance-impinging stereotypes? Two studies explored these questions. Participants completed a difficult math or verbal test in 3-person groups, each of which included 2 additional people of the same sex as the participant (same-sex condition) or of the opposite sex (minority condition). Female participants in the minority condition experienced performance deficits in the math test only, whereas males performed equally well on the math test in the two conditions. Further investigation showed that females' deficits were proportional to the number of males in their group. Even females who were placed in a mixed-sex majority condition (2 females and 1 male) experienced moderate but significant deficits. Findings are discussed in relation to theories of distinctiveness, stereotype threat, and tokenism.
On the Bistability of Sine Wave Analogues of Speech
Authors: Remez Robert E. , Pardo Jennifer S. , Piorkowski Rebecca L. , Rubin Philip E.
Published: March 2003

Our studies revealed two stable modes of perceptual organization, one based on attributes of auditory sensory elements and another based on attributes of patterned sensory variation composed by the aggregation of sensory elements. In a dual-task method, listeners attended concurrently to both aspects, component and pattern, of a sine wave analogue of a word. Organization of elements was indexed by several single-mode tests of auditory form perception to verify the perceptual segregation of either an individual formant of a synthetic word or a tonal component of a sinusoidal word analogue. Organization of patterned variation was indexed by a test of lexical identification. The results show the independence of the perception of auditory and phonetic form, which appear to be differently organized concurrent effects of the same acoustic cause.
Numerical Subtraction in the Pigeon: Evidence for a Linear Subjective Number Scale
Authors: Brannon Elizabeth M. , Wusthoff Courtney J. , Gallistel C.R. , Gibbon John
Published: March 2003

When humans and animals compare two numbers, responding is faster and more accurate with increasing numerical disparity and decreasing numerical size. Researchers explaining these distance and size effects often assume that the subjective number continuum is logarithmically compressed. An alternative hypothesis is that the subjective number continuum is linear, but positions farther along it are proportionately fuzzier, that is, less precisely located. These two hypotheses have been treated as functionally equivalent because of their similar empirical predictions. The current experiment sought to resolve this issue with a paradigm originally developed to address the subjective representation of time (time left). In our adaptation, pigeons were required to compare a constant number with the number remaining after a numerical subtraction. Our results indicate that subjective number is linearly, not logarithmically, related to objective number.
Children Creating Language: How Nicaraguan Sign Language Acquired a Spatial Grammar
Authors: Senghas Ann , Coppola Marie
Published: March 2003

It has long been postulated that language is not purely learned, but arises from an interaction between environmental exposure and innate abilities. The innate component becomes more evident in rare situations in which the environment is markedly impoverished. The present study investigated the language production of a generation of deaf Nicaraguans who had not been exposed to a developed language. We examined the changing use of early linguistic structures (specifically, spatial modulations) in a sign language that has emerged since the Nicaraguan group first came together. In under two decades, sequential cohorts of learners systematized the grammar of this new sign language. We examined whether the systematicity being added to the language stems from children or adults; our results indicate that such changes originate in children aged 10 and younger. Thus, sequential cohorts of interacting young children collectively possess the capacity not only to learn, but also to create, language.
Driven to Distraction: Dual-Task Studies of Simulated Driving and Conversing on a Cellular Telephone
Authors: Strayer David L. , Johnston William A.
Published: March 2003

Dual-task studies assessed the effects of cellular-phone conversations on performance of a simulated driving task. Performance was not disrupted by listening to radio broadcasts or listening to a book on tape. Nor was it disrupted by a continuous shadowing task using a handheld phone, ruling out, in this case, dual-task interpretations associated with holding the phone, listening, or speaking. However, significant interference was observed in a word-generation variant of the shadowing task, and this deficit increased with the difficulty of driving. Moreover, unconstrained conversations using either a handheld or a hands-free cell phone resulted in a twofold increase in the failure to detect simulated traffic signals and slower reactions to those signals that were detected. We suggest that cellular-phone use disrupts performance by diverting attention to an engaging cognitive context other than the one immediately associated with driving.
Very Happy People
Authors: Diener Ed , Seligman Martin E.P.
Published: March 2003

A sample of 222 undergraduates was screened for high happiness using multiple confirming assessment filters. We compared the upper 10% of consistently very happy people with average and very unhappy people. The very happy people were highly social, and had stronger romantic and other social relationships than less happy groups. They were more extroverted, more agreeable, and less neurotic, and scored lower on several psychopathology scales of the Minnesota Multiphasic Personality Inventory. Compared with the less happy groups, the happiest respondents did not exercise significantly more, participate in religious activities significantly more, or experience more objectively defined good events. No variable was sufficient for happiness, but good social relations were necessary. Members of the happiest group experienced positive, but not ecstatic, feelings most of the time, and they reported occasional negative moods. This suggests that very happy people do have a functioning emotion system that can react appropriately to life events.
Variability and Detection of Invariant Structure
Authors: Gómez Rebecca L.
Published: March 2003

Two experiments investigated learning of nonadjacent dependencies by adults and 18-month-olds. Each learner was exposed to three-element strings (e.g., pel-kicey-jic) produced by one of two artificial languages. Both languages contained the same adjacent dependencies, so learners could distinguish the languages only by acquiring dependencies between the first and third elements (the nonadjacent dependencies). The size of the pool from which the middle elements were drawn was systematically varied to investigate whether increasing variability (in the form of decreasing predictability between adjacent elements) would lead to better detection of nonadjacent dependencies. Infants and adults acquired nonadjacent dependencies only when adjacent dependencies were least predictable. The results point to conditions that might lead learners to focus on nonadjacent versus adjacent dependencies and are important for suggesting how learning might be dynamically guided by statistical structure.
Perceived Discrimination in the Context of Multiple Group Memberships
Authors: Levin Shana , Sinclair Stacey , Veniegas Rosemary C. , Taylor Pamela L.
Published: March 2003

This study examined the joint impact of gender and ethnicity on expectations of general discrimination against oneself and one's group. According to the double-jeopardy hypothesis, women of color will expect to experience more general discrimination than men of color, White women, and White men because they belong to both a low-status ethnic group and a low-status gender group. Alternatively, the ethnic-prominence hypothesis predicts that ethnic-minority women will not differ from ethnic-minority men in their expectations of general discrimination because these expectations will be influenced more by perceptions of ethnic discrimination, which they share with men of color, than by perceptions of gender discrimination. All results were consistent with the ethnic-prominence hypothesis rather than the double-jeopardy hypothesis.
Electrophysiological Responses to Errors and Feedback in the Process of Action Regulation
Authors: Luu Phan , Tucker Don M. , Derryberry Douglas , Reed Marjorie , Poulsen Catherine
Published: March 2003

The anterior cingulate cortex (ACC) is believed to be involved in the executive control of actions, such as in monitoring conflicting response demands, detecting errors, and evaluating the emotional significance of events. In this study, participants performed a task in which evaluative feedback was delayed, so that it was irrelevant to immediate response control but retained its emotional value as a performance indicator. We found that a medial frontal feedback-related negativity similar to the error-related negativity (ERN) tracked affective response to the feedback and predicted subsequent performance. Source analysis of the feedback-related negativity and ERN revealed a common dorsomedial ACC source and a rostromedial ACC source specific to the ERN. The oscillatory nature of these sources provides further evidence that the ERN reflects ongoing theta activity generated in the mediofrontal regions. These results suggest that action regulation by the cingulate gyrus may require the entrainment of multiple structures of the Papez corticolimbic circuit.
Phonological Influences on Lexical (Mis)Selection
Authors: Ferreira Victor S. , Griffin Zenzi M.
Published: March 2003

Speakers produce words to convey meaning, but does meaning alone determine which words they say? We report three experiments that show independent semantic and phonological influences converging to determine word selection. Speakers named pictures (e.g., of a priest) following visually presented cloze sentences that primed either semantic competitors of the target object name (“The woman went to the convent to become a …”), homophones of the competitors (“I thought that there would still be some cookies left, but there were …”), or matched unrelated control object names. Primed semantic competitors (nun) were produced instead of picture names more often than primed unrelated control object names, showing the well-documented influence of semantic similarity on lexical selection. Surprisingly, primed homophone competitors (none) also substituted for picture names more often than control object names even though they only sounded like competitors. Thus, independent semantic and phonological influences can converge to affect word selection.
Competition and Contracting in the Transition from CCT to Best Value: Towards a More Reflexive Regulation?
Authors: Vincent‐Jones Peter
Published: March 2003

Following publication of the government’s proposals for a statutory framework of Best Value, and the introduction of regulations increasing the flexibility of CCT pending its abolition, this paper examines the relationship between the compulsory regime and its likely successor. First, the paper suggests that the Best Value frame‐work is likely to impose a range of regulatory, monitoring and enforcement constraints similar in effect to the formal requirements that operate under CCT. Continuity with Conservative policy will be reinforced practically through transitional arrangements for the gradual abolition of CCT and the phased introduction of its replacement. Second, the paper argues that contracting is likely to continue to have a significant role under the new regime as the natural adjunct to the voluntary competitive processes that will be the preferred management tools for securing improvements in service performance. Open tendering and public‐private sector partnership arrangements, both of which imply contractual governance, are given explicit priority in the consultation document over benchmarking, performance indicators and other comparative public management mechanisms. Third, the paper argues that local authorities are likely to want to retain and develop contracting arrangements that potentially permit a degree of control over service provision that might not be available were more radical service‐providing alternatives to be adopted, involving the complete transfer of functions outside the public sector and/or their vesting in independent companies. Finally, the paper assesses the transition from CCT to Best Value from the theoretical perspective of responsive and reflexive regulation. Following a brief account of the reflexive failures of CCT, the paper argues that, although the Best Value framework is characterized by inherently reflexive processes involving self‐review, consultation and standard‐setting, its relative success is likely to depend ultimately both on the tightness with which legislation is drafted and on the manner of its practical interpretation, implementation and enforcement.
Exploring Contracts as Reinvented Institutions in the Danish Public Sector
Authors: Greve Carsten
Published: March 2003

Contracts have been on the agenda in public sector reform in most OECD countries. In Denmark, contracts have been considered as one of the most important tools in reorganizing the public sector. The article examines the implementation of contract agencies in central government in Denmark during the 1990s. First, a review of contractual theory distinguishes between ‘hard’ and ‘soft’ contracting. Second, recent developments in contracting in Denmark are examined, and three phases of contract agencies are identified. Contracts have been supported by other tools for reporting on performance like annual reports. Third, it is argued that Denmark has put co‐operation and negotiation before more strict management and control. The Danish experience can be seen as an alternative to the principal‐agent model. The article finishes by discussing the pros and cons of the Danish approach, and suggests that although the pragmatic approach has merits, it may lead to problems in the future concerning the credibility of the whole project.
‘Accountability’: An Ever‐Expanding Concept?
Authors: Mulgan Richard
Published: March 2003

The scope and meaning of ‘accountability’ has been extended in a number of directions well beyond its core sense of being called to account for one’s actions. It has been applied to internal aspects of official behaviour, beyond the external focus implied by being called to account; to institutions that control official behaviour other than through calling officials to account; to means of making officials responsive to public wishes other than through calling them to account; and to democratic dialogue between citizens where no one is being called to account. In each case the extension is readily intelligible because it is into an area of activity closely relevant to the practice of core accountability. However, in each case the extension of meaning may be challenged as weakening the importance of external scrutiny
Local Councillors: Between Local ‘Government’ and Local ‘Governance’
Authors: Hansen Karin
Published: March 2003

With a two‐dimensional concept of ‘New Public Management’ as its point of departure, the article points to the development of a specific Danish model of NPM at the local level of government. In the municipalities the market‐oriented NPM dimension has been almost absent and the managerial dimension has been interpreted and translated into a ‘governance’‐oriented model that combines decentralized self‐ and user‐governance from below with centralized goal‐steering from above. This combined model institutes new governing roles including a new leadership role for elected councillors as central goal‐steering decision and policy makers. Rather than strengthening the local councillors, the new leadership role has turned out to be problematic for the elected councillors. The problems inherent in the new institutional role as goal‐steering decision makers are discussed and arguments are put forward in favour of a more ‘governance’ and less NPM and government‐oriented role for elected councillors. What seems to be needed is another new role that stresses local councillors as co‐governors and guardians of an inclusive and democratic form of local governance.
Improving Public Service Delivery: The Crossroads Between NPM and Traditional Bureaucracy
Authors: De Araújo Joaquim Filipe Ferraz Esteves
Published: March 2003

This article analyses a New Public Management (NPM) style of reform recently introduced in Portuguese public administration. The reform introduces new organizations to a method of delivering public services called ‘Citizen Shops’ (CS) (Lojas dos Cidadãos). Several public services are concentrated in a single building whose management follows the practices of the private sector concerning service delivery and opening times, rather like a ‘shopping centre’. ‘Citizen Shops’ is a kind of agencification and is an attempt to avoid the constraints of civil service red tape and bureaucratic resistance to change. The author argues that the extent to which new ideas were imported from NPM was limited and constrained by the institutional framework and the culture prevailing in Portuguese bureaucracy. Citizen Shops reproduced the hierarchical and centralized nature of service delivery and followed the traditional patterns of control. The prevailing structure is an important constraint on NPM development.
Groupware and teamwork in R&D: limits to learning and innovation
Authors: Ciborra Claudio U. , Patriotta Gerardo
Published: March 2003

In recent years the re‐engineering of R&D functions in large multinationals has often been accompanied by the emergence of groupware applications as strategic decision‐making tools, while the organization of work has shifted towards various forms of teamworking. There is however, little empirical evidence on the conditions and processes through which groupware and teamworking practices can be efficiently linked. This paper examines the experience in groupware adoption by two large multinationals, Hoffmann la Roche and Unilever, in selected areas of new product development: the final New Drug Application phase for a new anti AIDS drug in Roche and the development along an ‘innovation funnel’ of new oral care products in Unilever. Despite the variety of tasks, organizations, missions and technology deployed, similar themes seem to emerge regarding how large organizations are able to ‘host’ the new groupware applications. Learning processes seem to play a key role in the final integration of the technology in the workflow. Still, what seems to emerge is that despite its critical role, learning is not a sufficiently valued competence, at least in the organizations examined. As a consequence, the innovations tend to drift, lead to unexpected outcomes and many opportunities for learning from (mistakes and) innovations are simply missed. Factors responsible for such a state of affairs seem to be the power of the hierarchical context into which groupware and teamwork are introduced; the continuous jolts to which such context must undergo because of radical shifts in management and R&D strategy; the dialectics between local and global changes.
Career orientations of R&D professionals in Korea
Authors: Kim Youngbae , Cha Jongseok
Published: March 2003

This study empirically examined the relationships between career orientations of R&D professionals in Korea and other personal characteristics such as demographic factors, work‐related outcomes, and reward preferences. The results, based on the survey about 1,240 technical people in 15 R&D organizations, revealed five distinctive and independent career orientations: technical, manager, project, technical transfer, and entrepreneurial orientations. The career orientations of R&D professionals are found to be different between private and public sectors and to be associated with their education level and organizational tenure. It is also observed that R&D professionals with different career orientations exhibit different work‐related outcomes and reward preferences. For instance, technical‐oriented professionals tend to be more educated, to exhibit better job attitudes and technical performances, and to favor professional rewards. While those with manager and transfer orientations are longer‐tenured, have more positive job attitudes but lower technical performances, and prefer social status and prestige and career rewards in their organization. Both project‐ and entrepreneur‐oriented professionals exhibit a less positive attitude toward their organizations, but seek different reward schemes: the former pursues challenging R&D projects with autonomy and the latter favors financial returns. Finally, the implications of these findings for managing careers of R&D professionals are discussed.
Managing the process of market orientation by publicly funded laboratories: the case of CSIR, India
Authors: Gupta Ashok K. , Bhojwani H.R. , Koshal Rajindar , Koshal Manjulika
Published: March 2003

User‐interaction is the most important ingredient in achieving market orientation. In this paper, perceptions of senior scientists and directors in publicly funded R&D labs in India with primary mission to conduct applied research, were analysed to learn about their interaction with industry. The areas examined included: importance and frequency of labs' interaction with industry; barriers faced by labs in their efforts to interact with industry; and initiatives taken by labs to improve their interaction with industry. Recommendations are presented to improve lab‐industry interaction by analysing actions of labs that are more successful in transferring their technologies to industry as compared to their less successful counterparts.
Exploitation and diffusion of public research: the case of academic spin‐off companies in Italy
Authors: Chiesa Vittorio , Piccaluga Andrea
Published: March 2003

Scientific and technological knowledge is considered the most important raw material for economic growth. The attention on the exploitation of public research, undoubtedly one of the main sources of new scientific and technological knowledge, has increased in recent years. After reviewing some concepts regarding the exploitation of public research results, the paper focuses on the analysis of academic spin‐off companies as one of the most promising ways to transfer research results to the market place. The phenomenon of academic spin‐off companies is described using both international evidence and a recent survey regarding 48 Italian spin‐off companies.
Teamwork for innovation – the ‘troika’ of promotors
Authors: Hauschildt Jürgen , Kirchmann Edgar
Published: March 2003

The management of innovation requires ‘champions’ or ‘promotors’ who commit with enthusiasm to the new product or the new process idea. More complex innovations will require more than one promotor. Division of labour becomes an essential success factor. According to the promotor model, at least a dyad of a ‘power promotor’ and a ‘technology promotor’ is necessary to overcome the barriers of unwillingness and of ignorance. With growing complexity, additional problems of communication and process management will occur. This will demand a third team member, the ‘process promotor’, who is needed to overcome the barriers of non‐responsibility and non‐communication between the organisational units involved and to act as navigator of the process. In this article, we present an empirical investigation of 133 innovations in the German plant construction and engineering industry. The results strengthen the hypothesis that the level of success of an innovation depends on the existence of a ‘troika’ of promotors.
A comparative analysis of R&D project evaluation methods
Authors: Poh K.L. , Ang B.W. , Bai F.
Published: March 2003

A large number of methodologies for Research and Development (R&D) project evaluation have been developed and reported in the literature over the last few decades. Almost all of this literature focused on the mechanisms and underlying theoretical foundation on which the evaluation methods are based. Very little attention has been paid to the effectiveness and suitability of the techniques, especially a comparison of the techniques. This paper presents a comparative study on a number of classes of R&D evaluation methods based on the Analytic Hierarchy Process. We look into the various factors and characteristics of R&D evaluation methods that affect their suitability. A sensitivity analysis was also carried out to determine the critical factors.
A gene to drug venture: Poisson options analysis
Authors: Brach Marion A. , Paxson Dean A.
Published: March 2003

We provide a Poisson real option model of a gene‐to‐drug venture. First we describe a general new drug discovery programme as well as a specific secretory protein research programme. Then we model both the candidate secretory gene and the ‘hot’ gene discoveries as Poisson processes. Gene deal value sizes are modeled as lognormal distributions. Then we calculate the expected R&D value (EV) of the Poisson discoveries times the value distributions, for both stages. Finally, for generic collaborating‐funding arrangements, we show the Merton (1976) standard mixed diffusion‐jump option value, compared to a risk neutral ‘intrinsic’ value. Under simple assumptions, the real option value is substantial, even if there is no intrinsic value.
Valuation of venture capital investments: empirical evidence
Authors: Seppä Tuukka J. , Laamanen Tomi
Published: March 2003

Using the valuation data of 421 US venture capital transactions and 176 initial public offerings, we test a simple binomial valuation model in modelling the risk‐return profiles of venture capital investments. We find that the model is consistent with the previous knowledge on the risk‐return profile of venture capital investments. The results also confirm the hypotheses that early‐stage ventures have higher implied risk and implied volatility of the returns than more established ones.

Additionally, we analyse the predictive power of the binomial pricing model and compare it to corresponding ‘traditional’ models that utilize risk‐adjusted rates of return. We construct one‐step ex post return forecasts for the sample ventures and compare the results to the actually realized returns. The findings indicate that the fit of the binomial model is better than the fit of the corresponding ‘traditional’ models.

The results imply that option‐based methods have empirical relevance in the pricing analysis of privately held companies and projects. Furthermore, practitioners can benefit from using these methods when analysing the risk‐return structure of private companies and R&D projects.
Evaluating growth options as sources of value for pharmaceutical research projects
Authors: Loch Christoph H. , Bode‐Greuel Kerstin
Published: March 2003

The financial value of research projects is difficult to assess because they are highly uncertain. Often, the result is either an overly conservative approach to strategic innovation, based on net present value analyses, or an overly aggressive approach based on optimistic qualitative portfolios. R&D project evaluation requires recognizing threats as well as opportunities from uncertain events, and incorporating flexibility in managerial action in response to them. Real options pricing analysis is a widely discussed tool for evaluating such managerial flexibility.

The limitation of options pricing lies in its requirement for complete financial markets, in which a replicating asset can be found that reproduces (or, at least, is correlated with) the project’s payoffs in all possible states of the world. However, the major risks of research projects are typically project specific and cannot be replicated in external markets. In this situation, a decision tree is a better tool to represent managerial options during execution of the project, and to evaluate its value. A decision tree is equivalent to options pricing for risks that can be priced in the financial markets (if trading of securities is explicitly included), and moreover, it can incorporate risks and flexibility that are not traded in financial markets.

Using decision trees, we demonstrate a quantitative evaluation of compound growth options from research at BestPharma, a large international pharmaceutical company. A growth option is a future opportunity that may arise from a current R&D investment. The growth option may not be related to the primary purpose of the R&D project, or not even be directly foreseeable. Kester (1984) has argued that growth options may account for a large part of project value. BestPharma faced the problem of choosing among several strategic research initiatives. They developed a decision tree representation of the projects, which helped to provide transparency about project value and strategic options. Most importantly, carefully thinking through the tree helped to identify growth options, represented by additional branches in the tree, and to quantify that they represented major sources of value.
The influence of project novelty on the new product development process

Published: March 2003

In this paper we review the range of formal tools and techniques available to support the new product development process, and examine the use and usefulness of these by means of a survey of 50 projects in 25 firms. For each firm, we compare routine and novel development projects, and identify the influence of project novelty on the frequency of use and perceived usefulness of a range of different tools and methods. In terms of usefulness, focus groups, partnering customers and lead users and prototyping are all considered to be more effective for high novelty projects, and segmentation least useful. Cross‐functional development teams are commonplace for all types of project, but are significantly more effective for the high novelty cases. In addition, many tools rated as useful are not commonly used, and conversely some tools in common use are considered to be of limited use.
Small firm networks: a successful approach to innovation?
Authors: Hanna Victoria , Walsh Kathryn
Published: March 2003

This paper considers the increasing trend of inter–working among small firms. Networks of small firms co–operate in certain activities, such as marketing, purchasing, R&D, training or manufacturing. But does co–operation lead to innovation? To answer this question published evaluations of small firms co–operating for mutual benefit are reappraised. Inter–working among small firms is then investigated further by interviewing three network brokers. The brokers were funded by regional governments and they facilitated co–operation between small firms. These semi–structured discussions explored the key characteristics of successful networks, the responsibilities of the broker and the level of innovation occurring.

Networking is primarily a competitive response. It needs to evolve into a mechanism to enable small firms to develop innovative products and processes jointly. Small firms may have to rethink their approach to co–operation, and their motives for initiating inter–working if they are to benefit fully from co–operation.
Stakeholder analysis for R&D project management

R&D projects affect the interests of different stakeholders in different ways. Understanding the stakeholders and analysing their interests helps in the better management of R&D projects. In this paper we discuss a methodology to systematically analyse the stakeholders of R&D projects. This methodology includes Freeman’s (1984) three levels of analysis: rational, process and transactional. Based on these three levels, the stakeholder management capability of an R&D project is determined. The final stage is based on Mitchell et al. (1997) approach to analysing the dynamics of stakeholders. This methodology is illustrated using a New Zealand case relating to a road pricing R&D project.
Collaboration in R&D with universities and research centres: an empirical study of Spanish firms

Innovation is sometimes the result of collaboration between different agents with complementary resources. When companies make formal agreements to collaborate in R&D they do so with different types of organizations, such as their competitors, suppliers, and customers, or universities and research centres. This paper focuses on attempting to understand the reasons that lead companies to cooperate with universities and research centres and the characteristics of the relationship that this involves. The empirical study is based on a sample of 747 Spanish firms that took part in some type of collaborative R&D project between 1994 and 1996. Results indicate that cooperation with centres is a nation–wide phenomenon involving basic research, conducted under the sponsorship of different research support schemes promoted by central and regional administrations.
A portfolio–evaluation framework for selecting R&D projects
Authors: Chien Chen–Fu
Published: March 2003

This study aims to form the basis for constructing a framework for evaluating alternative portfolios of R&D projects. This study provides an extensive literature review on portfolio selection. Most of the existing studies deal with the portfolio selection problem by evaluating individual projects and then seeking ways to combine them for an R&D portfolio. However, the combination of individually good projects unnecessarily constitutes the optimal portfolio. In particular, this study discusses three portfolio effects: (1) the difference between the preference for the portfolio as a whole and the preference for the projects, (2) the interrelation among projects, (3) the size of portfolio selection problems. This study develops a three–phase framework for evaluating R&D portfolios and proposes a new taxonomy of the portfolio attributes (i.e. independent, interrelated, and synergistic). This study concludes with a discussion of future research, directed toward increasing the applicability of portfolio–selection approaches for managing R&D portfolios.
Standard–setting processes: evidence from two case studies
Authors: Chiesa Vittorio , Manzini Raffaella , Toletti Giovanni
Published: March 2003

In many hi–tech sectors one of the most important dimensions of competition is standardisation. This is particularly true in modular markets (i.e. markets characterised by the existence of modular architectures) and in network markets (i.e. markets where users would like to buy products compatible with those bought by others). Different processes may lead to the standard–setting. Sometimes there are fierce standardisation wars whereas in other cases competitors are able to agree on a common standard before the introduction of the technology on the market. In this paper we endeavour to provide an interpretative framework of the standardisation process and validate such a framework through an in–depth analysis of two case studies in a typical network market (the multimedia sector): the case of the Modem 56k and the case of the Information Appliances–Enhanced TV.

The two case studies offer some evidence of the standardisation process and of the growing importance of super–partes organisations (Standard Development Organisations) in the mediation process between different interests and technologies to impose a common standard on the market.
A utopian view of R&D functions
Authors: Brockhoff Klaus
Published: March 2003

Technology management research appears to have a much longer history than is commonly assumed. In this short paper attention is drawn to some of Francis Bacon's writings which appeared in the early seventeenth century, and which contain ideas on laboratory organization that still have relevance today. In fact, it is only recently that the same broadness of laboratory functions described in the earlier text has been re–discovered.
