ARLINGTON, Va.--(BUSINESS WIRE)--CACI International Inc (NYSE: CACI) announced today the release of Combating Asymmetric Threats: Offset Strategies to Prevail Against Asymmetric Threats, a report from the ninth symposium in the Asymmetric Threat symposia series co-sponsored by the Association of Old Crows (AOC), CACI, and the Center for Security Policy (CSP). Summarizing discussions and comments from the symposium, the report considers how offset strategies attempt to position the U.S. to prevail against resurging global power competition, multiregional conflicts, and cross-domain challenges. Copies of the report may be downloaded from the dedicated Asymmetric Threat website at asymmetricthreat.net, or from AOC, CACI, or CSP websites at www.crows.org, www.caci.com, or www.centerforsecuritypolicy.org. Held September 22, 2016 at the Gannett Conference Center in McLean, Va., the symposium featured keynote speakers Lieutenant General Jack Weinstein, Deputy Chief of Staff for Strategic Deterrence and Nuclear Integration, Headquarters, USAF; and Lieutenant General Michael T. Flynn, USA (Ret), Chairman and Chief Executive, Flynn Intel Group and former Director of the Defense Intelligence Agency. Panelists included leaders and experts from government, industry, and academia examining the technologies and operational concepts needed to support offset strategies and how these strategies may be applied across federal agencies to gain the advantage against asymmetric threats. The report content reflects the invocation of the Chatham House rule for the symposium and report as non-attributable forums. The report also presents the symposium’s discussions on additional national security challenges, many of the hybrid kind, stemming from the erosion of the U.S.’s technology advantages, constrained budgets, and convoluted acquisitions processes. Opportunities that may be found in offset strategies involving technologies such as human-machine teaming may need to be applied across federal agencies and the private sector, and may further involve pursuing agile acquisition processes and legal tools. Comments by the symposium leadership emphasized several aspects of the event’s proceedings. CACI Executive Chairman and Chairman of the Board Dr. J.P. (Jack) London, who gave the welcoming remarks at the symposium, said, “The Combating Asymmetric Threats: Offset Strategies to Prevail Against Asymmetric Threats report articulates the opportunities and pitfalls of countervailing strategies to give the U.S. an edge on today’s complex battlefields. We need innovative, multi-dimensional, and nuanced approaches that incorporate new technologies and coordinate resources across government and industry to defeat adversaries who challenge us in every domain. CACI and its partners also look forward to hosting the 10th symposium in the Asymmetric Threat series next fall to continue this critical national dialogue promoting our nation’s security and its position as a global leader.” According to AOC President Lisa Frugé-Cirilli, “Electromagnetic spectrum (EMS) operations have become a decisive and discriminating enabler of hybrid warfare and offset strategies. The Association of Old Crows continues to advocate harvesting the constructive synergies between cyber and electronic warfare to ensure technological superiority and multi-domain dominance. We recognize that we must be able to manage the EMS much better than we do today, respond more quickly to adaptive threats, and seek a better balance between defensive and offensive EMS operations. Participating in the Asymmetric Threat IX symposium allowed the AOC to underscore its focus on finding, forging, and fielding offset technologies, capabilities, and operational concepts. The EMS technological opportunities we have yet to master are no greater than those we have already overcome.” CSP President and Chief Executive Officer Frank Gaffney stated, “The Ninth Asymmetric Threat Symposium presented an array of timely treatments of critical national security topics. Especially valuable was an insightful discussion of how we can win against the global jihad movement and its allies.” Since its founding in 2008 by CACI Executive Chairman and Chairman of the Board Dr. J.P. (Jack) London and Lead Director on CACI’s Board of Directors Dr. Warren Phillips, the Asymmetric Threat symposium series has provided a forum for thought leadership on national security. Symposium One, co-sponsored by CACI and the National Defense University and held May 8, 2008 at the National Defense University in Washington, DC, defined the asymmetric threat problem. Symposium Two, co-sponsored by CACI and the U.S. Naval Institute (USNI) and held October 21, 2008 at Ft. Myer, Virginia, addressed the efficacy of soft power. Symposium Three, co-sponsored by CACI and USNI and held March 24, 2009 at Ft. Myer, concluded the series by addressing the role of smart power in defeating asymmetric threats. Symposium Four, co-sponsored by CACI and USNI and held March 2, 2010 at Ft. Myer, centered on countering challenges to the global supply chain. Symposium Five, co-sponsored by CACI, USNI, and CSP and held March 1, 2011 at the Carnegie Institution for Science in Washington, DC, focused on cyber challenges to the U.S.’s economy and industrial base. Symposium Six, co-sponsored by CACI, USNI, and CSP and held May 8, 2012 at the U.S. Navy Memorial in Washington, DC, addressed decision superiority. Symposium Seven, co-sponsored by AOC, CACI, and CSP and held April 2, 2013 at the Ronald Reagan Building and International Trade Center in Washington, DC, addressed the interplay of offensive and defensive measures in shaping the outcomes of asymmetric conflicts. Symposium Eight, co-sponsored by AOC, CACI, and CSP and held October 1, 2014 at the Gannett Conference Center in McLean, Virginia addressed role of cyber, electromagnetic spectrum dominance, and electronic warfare in defending the U.S. and assuring military operational superiority.

The Fourth Santa Fe Conference on Global & Regional Climate Change will be held on Feb 5-10, 2017. It is the fourth in a series organized and chaired by Petr Chylek of Los Alamos National Laboratory (LANL) and takes place intervals of 5 years or thereabouts. It is sponsored this year by LANL’s Center for Earth and Space Science and co-sponsored by the American Meteorological Society. I attended the Third in the series, which was held the week of Oct 31, 2011. I reported on it here in my essay “Climate cynicism at the Santa Fe conference”. In that report, I described my experiences and interactions with other attendees, whose opinions and scientific competence spanned the entire spectrum of possibility. Christopher Monckton represented one extreme end-member, with no scientific credibility, total denial of facts, zero acknowledgment of uncertainty in his position, and complete belief in a global conspiracy to promote a global warming fraud. At the opposite end were respected professional climate scientists at the top of their fields, such as Richard Peltier and Gerald North. Others, such as Fred Singer and Bill Gray, occupied different parts of the multi-dimensional phase space, having credentials but also having embraced denial—each for their own reasons that probably didn’t intersect. For me, the Third Conference represented an opportunity to talk to people who held contrary opinions and who promoted factually incorrect information for reasons I did not understand. My main motivation for attending was to engage in dialogue with the contrarians and deniers, to try to understand them, and to try to get them to understand me. I came away on good terms with some (Bill Gray and I bonded over our common connection to Colorado State University, where I was an undergraduate physics student in the 1970s) but not so much with others. I was ambitious and submitted four abstracts. I and my colleagues were pursuing uncertainty quantification for climate change in collaboration with other DOE labs. I had been collaborating on several approaches to it, including betting markets, expert elicitation, and statistical surrogate models, so I submitted an abstract for each of those methods. I had also been working with Lloyd Keigwin, a senior scientist and oceanographer at Woods Hole Oceanographic Institution and another top-of-his-field researcher. We submitted an abstract together about his paleotemperature reconstruction of Sargasso Sea surface temperature, which is probably the most widely reproduced paleoclimate time series other than the Mann et al. “Hockey Stick” graph. I had updated it with modern SST measurements, and in our abstract we pointed out that it had been misused by contrarians who had removed some of the data, replotted it, and mislabeled it to falsely claim that it was a global temperature record showing a cooling trend. The graph continues to make appearances. On March 23, 2000, ExxonMobil took out an advertisement in the New York Times claiming that global warming was “Unsettled Science”. The ad was illustrated with a doctored version of Lloyd’s graph (the inconvenient modern temperature data showing a warming trend had been removed). This drawing was very similar to one that had been generated by climate denier Art Robinson and his son for a Wall Street Journal editorial a couple months earlier. It wasn’t long before other distorted versions started showing up elsewhere, such as the Albuquerque Journal opinion page. The 2000 ExxonMobil version was just entered into the Congressional Record last week by Senator Tim Kaine during the Tillerson confirmation hearings. In 2011, my abstracts on betting, expert elicitation, and statistical models were all accepted, and I presented them. But the abstract that Lloyd and I submitted was unilaterally rejected by Chylek who said, “This Conference is not a suitable forum for [the] type of presentations described in [the] submitted abstract. We would accept a paper that spoke to the science, the measurements, the interpretation, but not simply an attempted refutation of someone else’s assertions (especially when made in unpublished reports and blog site).” The unpublished report he spoke of was the NIPCC/Heartland Institute report, which Fred Singer was there to discuss. After the conference, I spoke to one of the co-chairs about the reasons for the rejection. He said that he hadn’t seen it and did not agree with the reasons for the rejection. He encouraged Lloyd and me to re-submit it again for the 4th conference. So we did. Lloyd sent the following slightly-revised version on January 4. Keigwin (Science 274:1504–1508, 1996) reconstructed the SST record in the northern Sargasso Sea to document natural climate variability in recent millennia. The annual average SST proxy used δ18O in planktonic foraminifera in a radiocarbon-dated 1990 Bermuda Rise box core. Keigwin’s Fig. 4B (K4B) shows a 50-year-averaged time series along with four decades of SST measurements from Station S near Bermuda, demonstrating that at the time of publication, the Sargasso Sea was at its warmest in more than 400 years, and well above the most recent box-core temperature. Taken together, Station S and paleotemperatures suggest there was an acceleration of warming in the 20th century, though this was not an explicit conclusion of the paper. Keigwin concluded that anthropogenic warming may be superposed on a natural warming trend. In a paper circulated with the anti-Kyoto “Oregon Petition,” Robinson et al. (“Environmental Effects of Increased Atmospheric Carbon Dioxide,” 1998) reproduced K4B but (1) omitted Station S data, (2) incorrectly stated that the time series ended in 1975, (3) conflated Sargasso Sea data with global temperature, and (4) falsely claimed that Keigwin showed global temperatures “are still a little below the average for the past 3,000 years.” Slight variations of Robinson et al. (1998) have been repeatedly published with different author rotations. Various mislabeled, improperly-drawn, and distorted versions of K4B have appeared in the Wall Street Journal, in weblogs, and even as an editorial cartoon—all supporting baseless claims that current temperatures are lower than the long term mean, and traceable to Robinson’s misrepresentation with Station S data removed. In 2007, Robinson added a fictitious 2006 temperature that is significantly lower than the measured data. This doctored version of K4B with fabricated data was reprinted in a 2008 Heartland Institute advocacy report, “Nature, Not Human Activity, Rules the Climate.” On Jan. 9, Lloyd and I got a terse rejection from Chylek: “Not accepted. The committee finding was that the abstract did not indicate that the presentation would provide additional science that would be appropriate for the conference.” I had also submitted an abstract with Stephen Lewandowsky and James Risbey called “Bets reveal people’s opinions on climate change and illustrate the statistics of climate change,” and a companion poster entitled “Forty years of expert opinion on global warming: 1977-2017” in which we proposed to survey the conference attendees: Forecasts of anthropogenic global warming in the 1970s (e.g. Broecker, 1975, Charney et al., 1979) were taken seriously by policy makers. At that time, climate change was already broadly recognized within the US defense and intelligence establishments as a threat to national and global security, particularly due to climate’s effect on food production. There was uncertainty about the degree of global warming, and media-hyped speculation about global cooling confused the public. Because science-informed policy decisions needed to be made in the face of this uncertainty, the US Department of Defense funded a study in 1977 by National Defense University (NDU) called “Climate Change to the Year 2000” in which a panel of experts was surveyed. Contrary to the recent mythology of a global cooling scare in the 1970s, the NDU report (published in 1978) concluded that, “Collectively, the respondents tended to anticipate a slight global warming rather than a cooling”. Despite the rapid global warming since 1977, this subject remains politically contentious. We propose to use our poster presentation to survey the attendees of the Fourth Santa Fe Conference on Global and Regional Climate Change and to determine how expert opinion has changed in the last 40 years. I had attempted a similar project at the 3rd conference with my poster “Comparison of Climate Forecasts: Expert Opinions vs. Prediction Markets” in which my abstract proposed the following: “As an experiment, we will ask participants to go on the record with estimates of probability that the global temperature anomaly for calendar year 2012 will be equal to or greater than x, where x ranges in increments of 0.05 °C from 0.30 to 1.10 °C (relative to the 1951-1980 base period, and published by NASA GISS).” I included a table for participants to fill in, and even printed extra sheets to tack up on the board with my poster so I could compile them and report them later. This idea was a spinoff of work I had presented at an unclassified session of the 2006 International Conference on Intelligence Analysis on my research in support of the US intelligence community for which a broad spectrum of opinion must be used to generate an actionable consensus with incomplete or conflicting information. That was certainly the case in Santa Fe, where there were individuals (e.g. Don Easterbrook) who were going on record with predictions of global cooling. By the last day of the conference, several individuals had filled in the table with their probabilistic predictions and I decided to leave my poster up until the end of the day, which was how long they could be displayed according to the conference program. I wanted to plug it during my oral presentation on prediction markets so that I could get more participation. Unfortunately when I returned to the display room, my poster had been removed. Hotel employees did not know where it was, and the diverse probability estimates were lost. This year I would be more careful, as announced in my abstract. But the committee would have no part of it. On Jan 10 I got my rejection letter: Of the hundreds of abstracts I’ve submitted, this is the only conference that’s ever rejected one. As a frequent session convener and program committee chair myself, I am accustomed to providing poster space for abstracts that I might question, misunderstand, or disagree with. It has never occurred to me to look at the publication list of a poster presenter, But if I were to do that, I would be more thorough and look other information, including their coauthors’ publication lists and CVs as well. In this case, the committee might have discovered more than a few papers by one of them on the subject, such as Risbey and Kandlikar (2002) “Expert Assessment of Uncertainties in Detection and Attribution of Climate Change” in the Bulletin of the American Meteorological Society, or that Prof. Risbey was a faculty member in Granger Morgan’s Engineering and Public Policy department at CMU for five years, a place awash in expert elicitation of climate (I sent my abstract to Prof. Morgan–who I know from my AGU uncertainty quantification days–for his opinion before submitting it to the conference). At the very least, I would look at the previous work cited in the abstract. The committee would not have been puzzled by how to transform survey data into probabilistic projections if they had done so. They would have learned that the 1978 NDU study we cited had already established the methodology we were proposing to use. The NDU “Task I” was “To define and estimate the likelihood of changes in climate during the next 25 years…” using ten survey questions described in Chapter One (Methodology). The first survey question was on average global temperature. So the legitimacy of the method we were planning to use was established 40 years ago. I concluded after the 3rd Santa Fe conference that cynicism was the only attribute that was shared by the minority of attendees who were deniers, contrarians, publicity-seekers, enablers, or provocateurs. I now think that cynicism has something in common with greenhouse gases. Cynicism begets cynicism, to the detriment of society. There are natural-born cynics, and if they turn the rest of us into cynics then we are their amplifiers, just like water vapor is an amplifier of carbon dioxide’s greenhouse effect. We become part of a cynical feedback loop that generates distrust in science and the scientific method. I refuse to let that happen. I might have gotten a little steamed by an unfair or inappropriate rejection, but I’ve cooled off and my induced cynicism has condensed now. I am not going to assume that everyone is a cynic just because of a couple of misguided and misinformed decisions. As President Obama said in his farewell address, “If you’re tired of arguing with strangers on the Internet, try talking with one of them in real life.” So if you are attending the Santa Fe conference, I would like to meet with you. If you are flying into Albuquerque, where I live, drop me a line. Or meet me for a drink or dinner in Santa Fe. I can show you why Lloyd’s research really does provide additional science that is relevant to the conference. I can try to convince you that prediction markets are indeed superior to expert elicitation in their ability to forecast climate change. Maybe I can even talk you into going on record with your own probabilistic global warming forecast!

A field emission cathode comprises at least one electron emitting parcel, and at least one ion absorbing parcel each being electrically connected with each of the at least one electron emitting parcel. The electron emitting parcel includes a first substrate and a nano emission component disposed on the first substrate for emitting electrons in an electric field. The ion absorbing parcel is constituted by a second substrate, in which the electric conductivity of the first substrate is less than that of the second substrate. A field emission light comprises the said field emission cathode, a field emission anode and a power supply. Thus the positive ions in an electric field can be absorbed by ion absorbing parcels to suppress an ion bombardment in the electric field. The efficiency of the electric field of the field emission is then maintained, and the lifetime of the field emission light is enhanced.
