The diminishing signaling value of patents between early rounds of venture capital financing     

Sebastian Hoenen  Christos Kolympiris  Wilfred Schoenmakers  Nicholas Kalaitzandonakes 《Research Policy》2014

A long stream of research has documented the positive effects that patents bring about to emerging firms in high technology industries. The general consensus is that patents contribute to firm growth because they confer monopolistic market rights, offer protection from competitors, increase the negotiating position of patent holders and other benefits. What has received relatively less attention in the literature is whether patents act as a signal that attracts investors such as venture capital firms. The handful of studies that have addressed that question has not analyzed whether the signaling function of patents decreases after the initial attraction of venture capital, as information asymmetries between investors and target firms reduce. In this study we hypothesize that patent activity has a signaling value that diminishes once information asymmetries between investors and funded firms lessen. To study our proposition we draw upon a longitudinal dataset of more than 580 U.S.-based biotechnology firms to empirically demonstrate that biotechnology firms that have submitted patent applications substantially increase the level of funding they receive for their first round of financing. In line with a reduction of information asymmetries once the initial investment has materialized, patent applications and granted patents have no effect on the growth of venture capital funds raised during the second round of financing. We conclude the study with a discussion of avenues for new research, implications for policy makers that consider the usefulness of the current patent system and with insights that can be employed by managers of firms in knowledge intensive areas such as biotechnology.  相似文献   

The use of source-related strategies in evaluating multiple psychology texts: a student–scientist comparison     

Sarah von der Mühlen  Tobias Richter  Sebastian Schmid  Elisabeth Marie Schmidt  Kirsten Berthold 《Reading and writing》2016,29(8):1677-1698

Multiple text comprehension can greatly benefit from paying attention to sources and from using this information for evaluating text information. Previous research based on texts from the domain of history suggests that source-related strategies are acquired as part of the discipline expertise as opposed to the spontaneous use of these strategies by students just entering a field. In the present study, we compared the performance of students and scientists in the domain of psychology with regard to (a) their knowledge of publication types, (b) relevant source characteristics, (c) their use of sources for evaluating the credibility of multiple texts, and (d) their ability to judge the plausibility of argumentative statements in psychological texts. Participants worked on a battery of newly developed computerised tests with a think-aloud instruction to uncover strategies that scientists and students used when reading a text. Results showed that scientists scored higher in all of the assessed abilities and that these abilities were positively correlated with each other. Importantly, the superior performance of scientists in evaluating the credibility of multiple texts was mediated by their use of source information. Implications are discussed in terms of discipline expertise.  相似文献   

Incidental vocabulary acquisition from listening to stories: a comparison between read-aloud and free storytelling approaches     

Jan Lenhart  Wolfgang Lenhard  Enni Vaahtoranta  Sebastian Suggate 《教育心理学》2018,38(5):596-616

Shared-book reading is a well-established intervention to foster vocabulary development. Factors influencing its effectiveness are, however, less well studied, particularly with regard to story-delivery. We contrasted a read-aloud with a free storytelling approach and tested effects on vocabulary learning. In the first study, 83 preschoolers aged three to six were told six stories in a randomised, single-blind and counterbalanced design. Stories were either read aloud or told freely and included rare target-words. Measures of target-word acquisition, receptive vocabulary, phonological working memory and speech comprehension were administered. There was a small to moderate learning gain (d = .37), but no effect of story-delivery. In a second study, 24 of the youngest and 24 of the oldest participants were tested again, using the same procedure but with stories designed to be more intrinsically motivating and age-appropriate. Results indicated negligible vocabulary gains (d = .08) and no effect of story-delivery, except for small differences in child behaviour during storytelling.  相似文献

Motivational interference in learning: The impact of leisure alternatives on subsequent self-regulation     

Stefan Fries  Franziska Dietz  Sebastian Schmid 《Contemporary educational psychology》2008,33(2):119-133

Students are often obliged to fulfill home assignments for school. While being engaged into such compulsory schooling, learners may be tempted to switch to a leisure alternative. Whenever students pursue the learning task although attractive leisure alternatives are present, thoughts about the missed activity can lead to motivational interference. Thus, self-regulation in learning does not only depend on the learning task itself but also on the dismissed alternatives. In a questionnaire study 704 students (mean age: 13.5) were confronted with hypothetical conflicts between a school activity and a leisure activity. The students envisioned themselves in the course of both activities after the decision. As predicted, self-reported self-regulation depended on the valences of both activities. High valence of the performed activity was related to better self-regulation, whereas high valence of the alternative activity resulted in worse self-regulation.  相似文献   

Effect of Internet Literacy in Understanding Older Adults’ Social Capital and Expected Internet Support     

Juan Sebastian Rios  Donghee Yvette Wohn  Yu-Hao Lee 《Communication Research Reports》2019,36(2):93-102

This article investigates whether knowledge of Internet usage among older adults is related to social capital as well as their expectations to obtain social support online. A U.S. national survey of adults aged 60 and older (n = 1,101) found that Internet literacy is significantly associated with their expected Internet support and bridging and bonding social capital even after controlling for age, Internet use, and other factors.  相似文献   

Cognitive and Attitudinal Predictors Related to Line Graphing Achievement among Elementary Pre-service Teachers     

Sebastian Szyjka  Frackson Mumba  Kevin C. Wise 《Journal of Science Teacher Education》2011,22(7):563-578

The purpose of this study was to determine the extent to which six cognitive and attitudinal variables predicted pre-service elementary teachers’ (N = 87) performance on line graphing. Predictors included reading comprehension and mathematics scores, logical thinking performance scores, as well as measures of attitudes toward science, mathematics and graphing. Results indicated that mathematical and logical thinking ability were the most significant predictors of line graph performance among the other variables, accounting for 41% of the total variability. Findings from this study suggest that elementary science education programs augment instruction to include aspects of mathematics and logical thinking.  相似文献   

Peer acceptance and peer status in relation to students’ special educational needs,migration biography,gender and socio-economic status     

Sebastian Wahl  Mike Trauntschnig  Lisa Hoffmann  Susanne Schwab 《Journal of Research in Special Educational Needs》2022,22(3):243-253

Research within the context of inclusive education is strongly focused on the investigation of students’ special educational needs (SEN). However, a broader understanding of inclusion requires consideration of other factors that may compromise inclusion, especially when it comes to social participation. This study investigates the social participation of 512 students from Austrian secondary mainstream schools. Aside from students’ SEN, their migration biography, gender and socio-economic status (SES) were also considered. Students’ social participation was measured using peer nominations and peer status. The results indicate that, apart from students with SEN, those with a migration biography and low SES are at risk of low social participation. Amongst the popular students, those with SEN were significantly underrepresented. Regarding peer nominations, students with SEN received less positive and more negative nominations compared to those without SEN. Similar effects for negative nominations were found for students with migration biography and extreme SES. The results suggest that being at risk of low social participation is not only a problem for students with SEN but also a problem for those belonging to minority groups. In terms of research and practical implications (e.g., prevention of the negative outcomes of low social participation), the results of the current study suggest considering student diversity in a broader sense. Furthermore, students from other minority groups, such as those with a migration biography or students from low socio-economic status backgrounds (SES), are likely to suffer from social exclusion.  相似文献   

Conflicting values and their impact on learning     

Stefan Fries  Sebastian Schmid  Franziska Dietz  Manfred Hofer 《European Journal of Psychology of Education - EJPE》2005,20(3):259-273

Based on Inglehart’s (1997) idea that the importance of modern values is challenged by a growing importance of postmodern values in postindustrialised sociaties, we analyse the consequences of students’ attempts to integrate (modern) achievement values and (postmodern) well-being values. Since opportunities for value integration are limited, students should frequently experience conflicts, whether to work for school or to engage in free time activities. In a questionnaire study, students (n=184) showed mostly high scores in both, achievement and well-being values. Value conflict — measured by a specific conflict formula — was related to the frequency of action conflicts as well as to the reported difficulty to decide which action to pursue. Values predicted the students’ school-related decisions. Furthermore, students with high achievement values reported better performance in school-related tasks than students with high well-being values. Finally, values were systematically related to time investment and grades.  相似文献   

Links between early oral narrative and decoding skills and later reading in a New Zealand sample*     

Elizabeth Schaughency  Sebastian Suggate  Elaine Reese 《Australian Journal of Learning Difficulties》2017,22(2):109-132

Abstract

We examined earlier oral narrative and decoding and later reading in two samples spanning the first four years of reading instruction. The Year 1 sample (n = 44) was initially assessed after one year of instruction (M = 6; 1 years) and followed through their third year (M = 8; 1 years); the Year 2 sample (n = 34) assessed after two years of instruction (M = 7; 0 years) and followed to their fourth year (M = 9; 0 years). Oral narrative and decoding were assessed initially, oral reading, retell, and maze fluency, plus reading age, obtained at outcome. For the Year 2 sample, oral narrative and decoding contributed to oral reading and comprehension two years later. For the Year 1 sample, decoding contributed to most reading outcomes, with narrative quality uniquely predicting Year 3 retell fluency. Post-hoc exploratory analyses suggest story memory indirectly contributed to Year 3 reading via Year 2 retell.  相似文献
