Computer software patents: Some perspectives and misunderstandings

The importance that in-house software plays today in many organizations is without question. Perspectives of efficiencies, effectiveness, competitive advantage, and so on are but three areas where such applications exist. Many organizations have adopted measures to protect such software as a specific type of intellectual property. In the 1990s quite often the form of protection taken is software patents. The understanding and enthusiasm about software patents that is exhibited by organizations is not often shared by information systems researchers, however. For the most part, IS researchers dismiss software patents as an appropriate protective measure. This paper presents some background on patents and their applicability to software. Some US and international perspectives are also discussed to provide the reader with a somewhat broader perspective. We then discuss several IS research endeavors that either dismiss patents, or treat them incorrectly. We conclude with a research agenda for IS researchers. the Department of Computer Information Systems & Quantitative Analysis, University of Arkansas. She has conducted extensive research in the area of the law and information technology. Her published research has appeared in MIS Quarterly, Journal of Management Information Systems, and Knowledge and Policy. His research interests include examination of the strategic aspects of information systems and the relationship between the law and information technology. His research has been published in Information Systems Research, MIS Quarterly, and the Journal of Management Information Systems. Her current research is focused on interogranizational systems and the human relationships that exist in parallel to these systems.     

Prime time advertisements: Repetition priming from faces seen on subject recruitment posters

Repetition priming is defined as a gain in item recognition after previous exposure. Repetition priming of face recognition has been shown to last for several months, despite contamination by everyday exposure to both experimental and control faces in the interval. Here we show that gains in face recognition in the laboratory are found from faces initially seen in a rather different context— on subject recruitment posters, even when the advertisements make no specific mention of experiments involving face recognition. The priming was greatest when identical pictures were shown in the posters and in the test phase, although different views of faces did give significant priming in one study. Follow-up studies revealed poor explicit memory for the faces shown on the posters. The results of these experiments are used to develop a model in which repetition priming reflects the process of updating representations of familiar faces.     

The importance of ‘mass’ in line drawings of faces

Previous research (Davies, Ellis and Shepherd, 1978; Rhodes, Brennan and Carey, 1987) has shown that accurate line drawings of familiar faces are identified rather poorly. However, artists can produce lifelike portraits with pen and ink, and Pearson and Robinson (1985) described an automatic method for producing computer-drawn sketches (‘cartoons’) of faces which appear very similar to those produced by a human artist. In this paper we show that subjects can identify famous faces depicted in such computer-drawn ‘cartoons’ almost as well as full grey-scale images. The cartoon algorithm comprises two components. One component draws lines at the locations of intensity changes corresponding to luminance valleys and edges (the ‘valledge’ detector). The other component applies a ‘threshold’ to the original intensity distribution, and replaces any area darker than threshold with black. Thus the full cartoon contains both ‘line’ and ‘mass’. Neither the valledges nor the threshold components alone were as well identified as full cartoons containing both components. The results suggest that the addition of the threshold component adds significantly to the identifiability of line drawings of faces.     

Social Comparisons and Adjustment Among Cardiac Patients1

The research examined social comparisons, affiliative choices, and their relation to adjustment among patients in a cardiac rehabilitation program. Consistent with Taylor and Lobel (1989), evaluative and affiliative processes diverged, with patients making downward evaluations (Wills, 1981) but choosing to affiliate with those who were better off than themselves. Consistent with predictions, downward evaluation was associated with better psychological adjustment, supporting the idea that these comparisons meet self-enhancement needs; upward affiliations were associated with hopefulness and inspiration, as well as with the perception that such comparisons provide information that is useful for improving one's own condition. The implications of evaluative comparison and affiliative activities for coping is discussed.     

The role of movement in the recognition of famous faces

The effects of movement on the recognition of famous faces shown in difficult conditions were investigated. Images were presented as negatives, upside down (inverted), and thresholded. Results indicate that, under all these conditions, moving faces were recognized significantly better than static ones. One possible explanation of this effect could be that a moving sequence contains more static information about the different views and expressions of the face than does a single static image. However, even when the amount of static information was equated (Experiments 3 and 4), there was still an advantage for moving sequences that contained their original dynamic properties. The results suggest that the dynamics of the motion provide additional information, helping to access an established familiar face representation. Both the theoretical and the practical implications for these findings are discussed.     

TEACHING GENERALIZED RECEPTIVE AND PRODUCTIVE BEHIND-FRONT DISCRIMINATIONS TO TWO RETARDED CHILDREN1

Typically, a generalized discrimination for two linguistic forms (e.g., “behind the (noun)” and “in front of the (noun)”) has been developed in a sequence of three treatment conditions, with generative usage developed for each form consecutively in the first two conditions and a generalized discrimination developed for those forms in the third condition. Moreover, generalized discriminations have typically been measured by a set of unreinforced probes, rather than by first-trial performances across a series of new tasks, as in some studies that have taught generative usage of a single form of language. In this study, successive sets of instructions were presented to two children. Each set contained four tasks, the four possible combinations of two new nouns with the linguistic forms “Put the (noun) behind the (noun)” and “Put the (noun) in front of the (noun)”. For each set, receptive usage of nouns was taught, and then the four instructions were presented, once each, to test for generative usage of the prepositional forms. First-trial performances were never prompted. After a baseline of five sets of tasks, correct first-trial performances earned praise and tokens. Also, in each set with three or fewer such performances, the specific receptive discriminations were taught to a criterion before presentation of the next set. Successive sets were presented until all first-trial performances were correct in five consecutive sets, whereupon this generalized discrimination was reversed and subsequently reinstated. Similar procedures were then used to teach the same children a generalized productive-discrimination for the forms “behind the (noun)” and “in front of the (noun)”. This study demonstrated the development of generalized receptive and productive behind-front discriminations without the prior development of generative usage in each linguistic form and with measurement of the generalized discrimination across first-trial performances. The method may offer a less time-consuming procedure for the development and measurement of generalized discriminations in receptive and productive language.     

The linkages of cognitive processes, stress propensity, affect, and strain: experimental test of a cognitive model of the stress response

This research examined a model of the stress response that includes cognitive-affective stress propensity, cognitive-affective processes, experienced affective reactions, subjective stress, and strain constructs. Using partial least squares analysis, this model was found to provide a good fit with the data. Moderated multiple regression analyses found support for the hypothesized moderating effects of individual stress propensity on the relationships of stressors with cognitive-affective processes. The research and practical implications of these findings are discussed.     

The effects of alcohol and the salience of aggressive cues on triggered displaced aggression

Alcohol increases the aggression-augmenting effects of provocation. Theories of alcohol and aggression suggest that impaired cognitive processing induced by acute intoxication leads individuals to process aggression-inducing social cues differently depending on whether they are high or low in salience. We examined the effects of intoxication and aggressive cue salience within the triggered displaced aggression paradigm. An ethnically diverse sample of 74 primarily young adult participants (40 men and 34 women; M=23.28, SD=3.14 years) were recruited from the university community and surrounding area. All participants were provoked by an experimenter, randomly assigned to a 2 (alcohol condition: alcohol vs. placebo) x 2 (trigger salience: high vs. low salience) between-subjects design, and then given the opportunity to aggress against the undeserving triggering agent. As expected, intoxication combined with a salient triggering cue elicited the most displaced aggression among all conditions. These results provide the first evidence that the effect of alcohol on triggered displaced aggression is moderated by the salience of the triggering event.     

Slurs, Snubs, and Queer Jokes: Incidence and Impact of Heterosexist Harassment in Academia

Previous research has suggested that overt hostility against sexual minorities is associated with decrements in their well-being. However, subtler forms of heterosexism and their potential effects have been overlooked, heterosexuals have not been asked how they fare in a heterosexist environment, and no research has examined whether women and men might respond differently to heterosexism. Data from 3,128 northwestern US university students (representing all sexual orientations) address these gaps. Approximately 40% reported experiences of heterosexist harassment (HH) in the past year, and those who encountered both ambient and personal HH reported worse psychological and academic well-being than those who encountered no HH. Similar patterns of findings held for sexual minorities and heterosexuals, and for women and men. This paper is based on a presentation given at the American Psychological Association Convention in Toronto, Ontario in August 2003.     

Transactional Leadership Revisited: Self–Other Agreement and Its Consequences

In a field study involving 209 leader–follower dyads, we examined leader–follower agreement regarding perceptions of the leaders' behavior style and follower outcomes of performance, organizational citizenship behavior, affective commitment, and trust in the leader. Using the self–other agreement paradigm, we found that agreement about a leader's style as transactional was positively related to these outcomes, whereas there was no relationship between agreement about a leader's transformational style and any of the outcomes. These findings support our view that a shared interpretation of the leader's transactional behavior is essential for positive follower outcomes, and may also be a necessary precondition for the effective use of transformational leader behavior. Implications for theory and future research are discussed.
