Selective search, sectoral patterns, and the impact on product innovation performance

The shift toward more open and interconnected innovation activities has been a major topic in recent academic and practitioner discussions. Firms must connect their in-house R&D activities with external partners, such as leading customers or universities, to increase the effectiveness of their innovation activities. Hence, management needs to define where to search for valuable knowledge in its environment. In this paper we argue that knowledge search has to reflect the heterogeneity of various knowledge sources with regard to the knowledge they can provide and how these sources can be activated. We hypothesize that search strategies driven by science, suppliers and the product market will contribute differently to innovation success with new-to-market versus imitated products. Moreover, we explore the effect of these types of knowledge search within different sectoral patterns of innovation. Our empirical analysis rests on a sample of almost 5000 firms from five Western European countries. The results support our hypotheses and highlight the potentials and shortcomings of different types of knowledge search.     

Degrees of value: comparing the contextual complexities of UK transnational education in Malaysia and Hong Kong

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage.

A network under stress: using embeddedness to understand uncertainty management and resilience in campus emergencies

Persistent school shootings have generated ongoing pressure to assess and enhance crisis communication effectiveness via strategies such as resilience-building and post-crisis restoration. A network perspective offers a robust, multilevel approach for examining complex information flows among community, campus, and individual actors affected by crises. Drawing on relational and structural embeddedness and Uncertainty Management Theory, we offer nine propositions that help explain structural and relational changes in a network over time. Although theoretically driven, these propositions are primarily functional, offering practical implications for safety officials and administrators trying to understand, prepare for, and respond to crises. Thus, we suggest measures and recommendations to improve information flow, uncertainty management, and resilience before, during, and after a crisis.     

Good intentions: providing students with skills to avoid accidental plagiarism

This article explores one librarian's experience with creating and implementing a plagiarism seminar as part of the library liaison program to the School of Public Health and Health Professions at the University at Buffalo. The changes and evolution of the seminar over several iterations are described. This article also examines student perceptions, misperceptions, and reactions to the plagiarism workshop.     

Effects of Methylphenidate on Academic Achievement from First to Second Grade

The objectives of the current study were to identify the long‐term effects of Methylphenidate (Ritalin) on cognitive ability and academic achievement. A retrospective/longitudinal design was utilised in the study with dependent measures being scores from the Iowa Tests of Basic Skills (ITBS). The study included 17 experimental subjects who were identified with ADHD and placed on Methylphenidate between first and second grade. For each experimental child, a control child without ADHD was matched based on gender, Verbal IQ score, and family structure. Results of the study revealed that the Methylphenidate group's achievement was lower both before and after medication even after being matched on verbal abilities. The results also indicated that after receiving medication the Methylphenidate group's rate of learning was similar to the Control groups on Reading, Word Analysis, Listening, Vocabulary, and overall achievement. Finally, a positive relationship between dosage level and Listening subtest scores was observed while a negative relationship was obtained between dosage level and Vocabulary subtest scores.

Encouraging intelligent failure in an MBA class

Failure has an important role to play in learning how to navigate highly uncertain organizational environments. But “failing fast” just for its own sake may in fact undermine learning if not set up or handled correctly. Using failure-based pedagogy, including generative failure, whole-person learning, and entrepreneurial thinking, an MBA course was designed and experienced by 48 students in three instances. Structured around a novel guiding framework of “brains, bravery, and belief,” the course has resulted in highly impactful learning for students. Student experiments are typically based around either exploring an entrepreneurial idea, developing or enhancing a particular skill, or applying skills and knowledge to help improve a societal problem. In each case, students are supported but also challenged to go beyond their comfort zones and encounter some intelligent failure in the journey. Regular reflection on their experiences, both from a cognitive and an affective perspective, is an essential element built into the course experience. The course, which itself was an experiment and not without its own instructive failures, is now an essential part of the MBA experience.     

Simplified method of designing FIR filter with controllable center frequency

A novel simplified method is presented to design FIR filter with controllable center frequency. The properties of transfer curves for all-phase filters are illustrated under 3 windowing conditions. By combining single-window all-phase filter design steps and double phase-shift combination, a series of design formulas for point-pass filter, notch filter, band-pass filter and band-stop filter are derived, thus the design computation complexity is greatly reduced. Experiments prove that the center frequency of all the filters can be accurately specified at arbitrary position by adjusting frequency parameters m and λ.
