Follow the leader or the pack? Regulatory focus and academic entrepreneurial intentions

Drawing on the academic entrepreneurship and regulatory focus theory literature, and applying a multilevel per- spective, this paper examines why university academics intend to engage in formal (spin-off or start-up companies and licensing university research) or informal (collaborative research, contract research, continuous professional development, and contract consulting) commercialization activities and the role local contextual factors, in partic- ular leaders and work-group colleagues (peers), play in their commercialization choices. Based on a survey of 395 science, technology, engineering, and mathematics (STEM) academics working in 14 Scottish universities, the research findings suggest that an individual’s chronic regulatory focus has a direct effect on their formal and informal commercialization intent. The results reveal that the stronger an individual’s chronic promotion focus the stronger their formal and informal commercialization intentions and a stronger individual chronic prevention focus leads to weaker intentions to engage in informal commercialization. In addition, when contextual interaction effects are considered, leaders and workplace colleagues have different influences on commercialization intent. On the one hand, promotion-focused leaders can strengthen and prevention-focused leaders can under certain cir- cumstances weaken a promotion-focused academic’s formal commercialization intent. On the other hand, the level of workplace colleague engagement, acting as a reference point, strengthens not only promotion-focused academ- ics’ intent to engage in formal commercialization activities, but also prevention-focused academics’ corresponding informal commercialization intent. As such, universities should consider the appointment of leaders who are strong role models and have a track record in formal and/or informal commercialization activities and also con- sider the importance workplace colleagues have on moderating an academic’s intention to engage in different forms of commercialization activities

Strong Hall voltage modulation in hybrid ferromagnet/semiconductor microstructures

We present a new magnetoelectronic device consisting of a µm-scale semiconductor cross junction and a patterned, electrically isolated, ferromagnetic overlayer with in-plane magnetization. The large local magnetic field emanating from the edge of the thin ferromagnetic film has a strong perpendicular magnetic component, B[perpendicular](r), which induces a Hall resistance, RH, in the microjunction. External application of a weak in-plane magnetic field reverses the magnetization of the ferromagnet and with it B[perpendicular](r), thus modulating RH. Our data demonstrate that this strong "local" Hall effect is operative at both cryogenic and room temperatures, and is promising for device applications such as field sensors or integrated nonvolatile memory cells

Transcutaneous electrical nerve stimulation for cancer pain in adults.

Background Cancer-related pain is complex and multi-dimensional but the mainstay of cancer pain management has predominately used a biomedical approach. There is a need for non-pharmacological and innovative approaches. Transcutaneous Electric Nerve Stimulation (TENS) may have a role for a significant number of patients but the effectiveness of TENS is currently unknown. Objectives The aim of this systematic review was to determine the effectiveness of TENS for cancer-related pain in adults. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE, CINAHL, PsychINFO, AMED and PEDRO databases (11/04/08). Selection criteria Only randomised controlled trials (RCTS) investigating the use of TENS for the management of cancer-related pain in adults were included. Data collection and analysis The search strategy identified 37 possible published studies which were divided between two pairs of review authors that decided on study selection. A study eligibility form was used to screen each abstract and where study eligibility could not be determined from the abstract, the full paper was obtained and assessed by one pair of review authors. A standardised data extraction sheet was used to collect information on the studies and the quality of the studies was assessed independently by two review authors using the validated five-point Oxford Quality Scale. Final scores were discussed and agreed between all four review authors. The small sample sizes and differences in patient study populations of the two included studies prevented meta-analysis. Main results Only two RCTs met the eligibility criteria (64 participants). These studies were heterogenous with respect to study population, sample size, study design, methodological quality, mode of TENS, treatment duration, method of administration and outcome measures used. In one RCT, there were no significant differences between TENS and placebo in women with chronic pain secondary to breast cancer treatment. In the other RCT, there were no significant differences between acupuncture-type TENS and sham in palliative care patients; this study was underpowered. Authors' conclusions The results of this systematic review are inconclusive due to a lack of suitable RCTs. Large multi-centre RCTs are required to assess the value of TENS in the management of cancer-related pain in adults

Economic Impacts of Yellow Starthistle on California Ranchers

While the significant ecosystem damage caused by invasive weeds has been well documented, the economic impacts of specific invasive weed species are poorly understood. Yellow starthistle (Centaurea solstitialis L., hereafter YST) is the most widespread non-crop weed in California, resulting in serious damage to forage on natural range and improved pasture. A survey was administered to California cattle ranchers to investigate YST infestation rates, loss of forage quantity and value, and control or eradication efforts. The results were used to estimate county-wide economic losses for three focus counties, as well as state-wide economic losses, due to YST in California. Total losses of livestock forage value due to YST on private land for the state of California are estimated at $7.96 million/year, with ranchers’ out-of-pocket expenditures on YST control amounting to$9.45 million/year. Together, these costs are the equivalent of 6-7% of the total annual harvested pasture value for the state. Therefore, while the impacts are relatively small within the statewide total agricultural production system, costs due to YST infestation significantly constrain California’s livestock grazing sector.nonnative species, invasive weeds, yellow starthistle, ranching profitability, forage, livestock
