A measure of knowledge flow between specific fields: Implications of interdisciplinarity for impact and funding.

ABSTRACT: Encouraging knowledge flow between mutually relevant disciplines is a worthy aim of research policy makers. Yet, it is less clear what types of research promote cross-disciplinary knowledge flow and whether such research generates particularly influential knowledge. Empirical questions remain as to how to identify knowledge-flow mediating research and how to provide support for this research. This study contributes to addressing these gaps by proposing a new way to identify knowledge-flow mediating research at the individual research article level, instead of at more aggregated levels. We identify journal articles that link two mutually relevant disciplines in three ways-aggregating, bridging, and diffusing. We then examine the likelihood that these papers receive subsequent citations or have funding acknowledgments. Our case study of cognitive science and educational research knowledge flow suggests that articles that aggregate knowledge from multiple disciplines are cited significantly more often than are those whose references are drawn primarily from a single discipline. Interestingly, the articles that meet the criteria for being considered knowledge-flow mediators are less likely to reflect funding, based on reported acknowledgements, than were those that did not meet these criteria. Based on these findings, we draw implications for research policymakers.

Project description:BackgroundNormal cell function requires timely and accurate transmission of information from receptors on the cell membrane (CM) to the nucleus. Movement of messenger proteins in the cytoplasm is thought to be dependent on random walk. However, Brownian motion will disperse messenger proteins throughout the cytosol resulting in slow and highly variable transit times. We propose that a critical component of information transfer is an intracellular electric field generated by distribution of charge on the nuclear membrane (NM). While the latter has been demonstrated experimentally for decades, the role of the consequent electric field has been assumed to be minimal due to a Debye length of about 1 nanometer that results from screening by intracellular Cl- and K+. We propose inclusion of these inorganic ions in the Debye-Huckel equation is incorrect because nuclear pores allow transit through the membrane at a rate far faster than the time to thermodynamic equilibrium. In our model, only the charged, mobile messenger proteins contribute to the Debye length.FindingsUsing this revised model and published data, we estimate the NM possesses a Debye-Huckel length of a few microns and find this is consistent with recent measurement using intracellular nano-voltmeters. We demonstrate the field will accelerate isolated messenger proteins toward the nucleus through Coulomb interactions with negative charges added by phosphorylation. We calculate transit times as short as 0.01 sec. When large numbers of phosphorylated messenger proteins are generated by increasing concentrations of extracellular ligands, we demonstrate they generate a self-screening environment that regionally attenuates the cytoplasmic field, slowing movement but permitting greater cross talk among pathways. Preliminary experimental results with phosphorylated RAF are consistent with model predictions.ConclusionThis work demonstrates that previously unrecognized Coulomb interactions between phosphorylated messenger proteins and intracellular electric fields will optimize information transfer from the CM to the NM in cells.

Project description:BackgroundIn this study, we aimed to assess health research funding allocation in South Korea by analysing the relationship between government funding and disease burden in South Korea, specifically focusing on cancers.MethodsThe relationship between research funding and the cancer burden, measured in disability-adjusted life-years (DALYs), was analysed using a linear regression method over a 10-year interval. Funding information on 25 types of cancer was obtained from the National Science and Technology Information Service portal in South Korea. Measures of cancer burden were obtained from Global Burden of Disease studies. The funding predictions were derived from regression analysis and compared with actual funding allocations. In addition, we evaluated how the funding distribution reflected long-term changes in the burden and the burden specific to South Korea compared with global values.ResultsKorean funding in four periods, 2005-2007, 2008-2010, 2011-2013 and 2015-2017, were associated with the cancer burden in 2003, 2006, 2009 and 2013, respectively. For DALYs, the correlation coefficients were 0.79 and 0.82 in 2003 and 2013, respectively, which were higher than the values from other countries. However, the changes in DALYs (1990-2006) were not associated with the funding changes (from 2005 to 2007 to 2015-2017). In addition, the value differences between Korean and global DALYs were not associated with Korean government research funding.ConclusionsAlthough research funding was associated with the cancer burden in South Korea during the last decade, the distribution of research funds did not appropriately reflect the changes in burden nor the differences between the South Korean and global burden levels. The policy-makers involved in health research budgeting should consider not only the absolute burden values for singular years but also the long-term changes in burden and the country-specific burden when they prioritise public research projects.

Project description:BackgroundEstablishment of the Canadian Institutes of Health Research (CIHR) in 2000 resulted in increased funding for health research in Canada. Since 2001, the number of proposals submitted to CIHR that, following peer review, are judged to be of scientific merit to warrant funding, has grown by 77%. But many of these proposals do not receive funding because of budget constraints. Given the role of Members of Parliament in setting government funding priorities, we surveyed Members of Parliament about their knowledge of and attitudes toward health research, health research funding and CIHR.MethodsAll Members of Parliament were invited to participate, or to designate a senior aide to participate, in a 15-minute survey of knowledge of and attitudes toward health research, health research funding and CIHR. Interviews were conducted between July 15, 2006, and Dec. 20, 2006. Responses were analyzed by party affiliation, region and years of service as a Member of Parliament.ResultsA total of 101 of 308 Members of Parliament or their designated senior aides participated in the survey. Almost one-third of respondents were senior aides. Most of the respondents (84%) were aware of CIHR, but 32% knew nothing about its role. Participants believed that health research is a critical component of a strong health care system and that it is underfunded. Overall, 78% felt that the percentage of total government spending directed to health research funding was too low; 85% felt the same way about the percentage of government health care spending directed to health research. Fifty-four percent believed that the federal government should provide both funding and guidelines for health research, and 66% believed that the business sector should be the primary source of health research funding. Participants (57%) most frequently defined health research as study into cures or treatments of disease, and 22% of participants were aware that CIHR is the main federal government funding organization for health research. Participants perceived health research to be a low priority for Canadian voters (mean ranking 3.8/10, with 1 being unimportant and 10 being extremely important [SD 1.85]).InterpretationOur results highlight significant knowledge gaps among Members of Parliament regarding health research. Many of these knowledge gaps will need to be addressed if health research is to become a priority.
