This paper analyzes the relation between the patenting behavior of startup firms and the progress of those firms through the venture capital cycle. Linking data relating to venture capital financing of software startup firms with data concerning the patents obtained by those firms, we find significant and robust positive correlations between patenting and several variables measuring the firm's performance (including number of rounds, total investment, exit status, receipt of late stage financing, and longevity). The data also show that (1) only about one in four venture-backed software firms acquired even one patent during the period of the study; (2) patenting practices very considerably among the sub-sectors of the software industry; and (3) the relationship between patent metrics and firm performance depends less on the size of the patent portfolio than on the firm's receipt of at least one patent.  相似文献   

Writing it down—writing it out—writing it up: researching our practice through action learning   总被引：1，自引：1，他引：0  

Pete Mann  Davina M. Clarke 《Action Learning: Research and Practice》2007,4(2):153-171

We dedicate this article to the late Professor John Morris, an appreciative inquirer into and true enabler of the writing of practice for each of us.

What value is added for writer and reader by intentionally keeping personal learning part of public researching? When a practitioner attends conscientiously to ‘the relationship with their research,’ does it make a difference to their learning and researching? If it does, can this difference also make a difference to the reader …? This paper addresses these kinds of queries from the standpoint of ‘scholarly practice,’ the research undertaken by mature managers and professionals who account in text for initiating and sustaining change within their complex contexts of work. Through exploring a variety of learning frames, the authors identify the distinctive opportunities and challenges in practice-led enquiry, and raise implications critically for the researching professional as well as for their ‘enablers’—the academic supervisors or fellow action-learning set members—who support and challenge the efforts of scholarly practitioners to make sense of and explicate their action. Revans's praxeology of action-based learning (systems alpha, beta and gamma) is extended as a research analogue for practice-led knowing. Ontological, methodological and epistemological perspectives are progressively deployed to examine critically the essentially reflexive nature of scholarly practice. The authors depict challenges in scholarly practice of establishing focus, incorporating others' thinking alongside one's own and asserting one's own voice. The paper concludes by warning of two ways in which enablers can unwittingly hijack the purpose of practice-led research.  相似文献   

Louisa's Birth     

R Mann 《The Journal of perinatal education》2011,20(4):182-184

In this column, Rachel Mann shares the story of the birth of her third daughter, Louisa. After a previous pregnancy loss, Mann chose to give birth to her third baby in a hospital with attending care from an obstetrician. In spite of the high-risk medical environment, she was able to have an unmedicated, powerful birth. Mann's careful planning, the support of her husband and doula, and her confidence in her ability to give birth helped make Louisa's birth all that Mann hoped it would be.  相似文献   

Motherhood,choice and the British media: a time to reflect     

L. Hadfield  N. Rudoe  J. Sanderson‐Mann 《Gender and education》2007,19(2):255-263

In this paper we ask: How is motherhood being represented in the British media, especially in relation to choice, age and fertility? Do media discourses reflect a redefinition or transformation of ‘motherhood’ in the twenty‐first century, and what implications do they have for feminist research into maternal identity and motherhood? As three Ph.D. students from The Open University, all working on different aspects of motherhood, we examine and discuss the significant debates around motherhood, fertility and choice taking place recently in the British media. In the context of increasing divergence from traditional family forms, advances in medical technology such as assisted reproductive techniques, and changing attitudes to sexual behaviour and marriage over the past few decades, motherhood and parenting remain contested sites in the public domain. The availability of contraception and of abortion has given rise to increased choice, and yet women’s fertility choices are increasingly subject to scrutiny and criticism. In particular, media debate in the UK has focused on challenges to traditional motherhood and the implication that the family is ‘in crisis’. This is particularly evident in the coverage of teenage mothers, older mothers and women who delay motherhood. Such media representations of older and younger mothers and those women who ‘leave it too late’ reveal significant insights into the social construction of motherhood.  相似文献   

Maintaining Suitable Standards of Scholarship     

Ronald A. Mann 《Computer Science Education》2013,23(3):309-311

If instruction is to command equal respect with research within academe, it must manifest the same high standards of scholarship expected of research. Journals devoted to pedagogy support this by maintaining high standards of scholarship in the articles they publish. This commentary identifies two examples of articles in Volume 1 of Computer Science Education which fail to meet even the most elementary standards of scholarship.  相似文献   

Involvement with child protective services: Is this a useful question in population-based surveys?     

Hayley A. Hamilton  Angela Boak  Robert E. Mann 《Child abuse & neglect》2013

Direct questions on child maltreatment in population-based surveys are often limited by ethical and methodological issues. This restricts the ability of researchers to examine an important aspect of early adversity and its relationship to health and behavior. An alternative to excluding issues of maltreatment entirely in population-based surveys is to include questions on child and family involvement with child protective services (CPS). A school-based adolescent survey that included a question on child and family involvement with CPS yielded results that were generally consistent with other studies relating child maltreatment to health and behavioral outcomes such as psychological distress symptoms, delinquency, aspects of bullying, and health service utilization. Such findings suggest that questions on involvement with CPS may be a reasonable proxy for child maltreatment. Despite the lack of information on the reason for involvement or specific categories of maltreatment, CPS involvement questions highlight the shared familial experience that surrounds CPS involvement and serves as a general reflection of an adverse experience that can be utilized by researchers interested in early experiences.  相似文献

A Kinetic Analysis of the Ground Leg During Sprint Running     

Ralph Mann  Paul Sprague 《Research quarterly for exercise and sport》2013,84(2):334-348

Abstract

Fifteen highly skilled sprinters were filmed while running at maximum velocity. The results were digitized and computer processed with interest focused on the muscle moments generated about the hip, knee, and ankle of the ground leg. Muscle activity about the hip consisted of extensor (concentric) dominance from foot descent, through foot strike, and into mid-support. Muscle dominance shifted to the hip flexors (eccentric) during mid-support and continued through takeoff. Muscle dominance at the knee demonstrated a pattern of flexor (eccentric, then concentric) dominance from foot descent through foot strike and into mid-support. Knee extensors (eccentric, then concentric) then achieved dominance through takeoff. During the later stages of takeoff, the dominance decreased or reversed briefly to flexor (eccentric) activity prior to a period of minimal activity following the toe-off position. From a period of minimal activity prior and subsequent to ground contact, the plantar flexors (eccentric, then concentric) of the foot were dominant throughout the ground phase. Qualitatively, the unexpected knee flexor dominance during foot strike was generated to limit the braking action created during this portion of ground contact. The unanticipated hip flexor dominance during takeoff served to rotate the upper body forward and into the approaching air phase. In addition, both of these actions allowed efficient use of the two-joint muscles of the leg during the critical phases of ground contact. Finally, the minimizing or reversing of the knee extensor dominance during the later stages of takeoff served to protect the joint from injury. Quantitatively, the magnitude of hip extensor/knee flexor activity during foot strike was significantly related (r = .70, p = .01) to the prior occurrences of related leg injury in the subjects.  相似文献   

Longitudinal prediction and prevention of early reading difficulty   总被引：5，自引：4，他引：1  

Virginia A. Mann 《Annals of dyslexia》1984,34(1):117-136

The results of many studies suggest that early reading problems are associated with deficiencies in certain spoken language skills. Children who encounter reading difficulty tend to be deficient in the perception of spoken words, the ability to retain linguistic material in temporary memory, and the ability to comprehend certain spoken sentences, as well as in their awareness about the phonological structure of spoken words. This paper summarizes these findings and provides an explanation in terms of the requirements of skilled reading. It further reviews the results of two longitudinal studies which show that inferior performance in kindergarten tests of language skills may presage future reading problems in the first grade. Based on these studies, procedures are suggested for kindergarten screening and for some ways of aiding children who, by virtue of inferior performance on the screening tests, might be considered at risk for early reading difficulties.
