Letrozole compared with tamoxifen for elderly patients with endocrine-responsive early breast cancer: the BIG 1-98 trial

PURPOSE: To explore potential differences in efficacy, treatment completion, and adverse events (AEs) in elderly women receiving adjuvant tamoxifen or letrozole for five years in the Breast International Group (BIG) 1-98 trial. METHODS: This report includes the 4,922 patients allocated to 5 years of letrozole or tamoxifen in the BIG 1-98 trial. The median follow-up was 40.4 months. Subpopulation Treatment Effect Pattern Plot (STEPP) analysis was used to examine the patterns of differences in disease-free survival and incidences of AEs according to age. In addition, three categoric age groups were defined: "younger postmenopausal" patients were younger than 65 years (n = 3,127), "older" patients were 65 to 74 years old (n = 1,500), and "elderly" patients were 75 years of age or older (n = 295). RESULTS: Efficacy results for subpopulations defined by age were similar to the overall trial results: Letrozole significantly improved disease-free survival (DFS), the primary end point, compared with tamoxifen. Elderly patients were less likely to complete trial treatment, but at rates that were similar in the two treatment groups. The incidence of bone fractures, observed more often in the letrozole group, did not differ by age. In elderly patients, letrozole had a significantly higher incidence of any grade 3 to 5 protocol-specified non-fracture AE compared with tamoxifen (P = .002), but differences were not significant for thromboembolic or cardiac AEs. CONCLUSION: Adjuvant treatment with letrozole had superior efficacy (DFS) compared with tamoxifen in all age groups. On the basis of a small number of patients older than 75 years (6%), age per se should not unduly affect the choice of adjuvant endocrine therapy.

Legislative Legacy: Big Changes in Legislative Article of 1972 Constitution -- Jerry Loendorf, Arlyne Reichert & Rich Bechtel “In the Crucible of Change”

The fulcrum upon which were leveraged many of the dramatic progressive changes in Montana that are documented "In the Crucible of Change" series was the lead up to, preparation, writing and adoption of the 1972 Montana Constitution. As Montana citizens exhibited their concern over the dysfunctional state government in MT under its 1889 Constitution, one of the areas that stood out as needing serious change was the Montana Legislature. Meeting for only sixty calendar days every two years, the Legislature regularly tried to carry off the subterfuge of stopping the wall clock at 11:59 PM on the sixtieth day and placing a shroud over it so they could continue to conduct business as if it were still the 60th day. Lawyers hired by the Anaconda Company drafted most bills that legislators wanted to have introduced. Malapportionment, especially in the State Senate where each county had one Senator regardless of their population, created a situation where Petroleum County with 800 residents had one senator while neighboring Yellowstone County with 80,000 people also had one senator -- a 100-1 differential in representation. Reapportionment imposed by rulings of the US Supreme Court in the mid-1960s created great furor in rural Montana to go along with the previous dissatisfaction of the urban centers. Stories of Anaconda Company “thumbs up – thumbs down” control of the votes were prevalent. Committee meeting and votes were done behind closed doors and recorded votes were non-existent except for the nearly meaningless final tally. People were in the dark about the creation of laws that affected their daily lives. It was clear that change in the Legislature had to take the form of change in the Constitution and, because it was not likely that the Legislature would advance Constitutional amendments on the subject, a convention seemed the only remedy. Once that Convention was called and went to work, it became apparent that the Legislative Article provided both opportunity for change and danger that too dramatic a change might sink the whole new document. The activities of the Legislative Committee and the whole Convention when acting upon Legislative issues provides one of the more compelling stories of change. The story of the Legislative Article of the Montana Constitution is discussed in this episode by three major players who were directly involved in the effort: Jerry Loendorf, Arlyne Reichert and Rich Bechtel. Their recollections of the activities surrounding the entire Constitutional Convention and specifically the Legislative Article provide an insider’s perspective of the development of the entire Constitution and the Legislative portion which was of such a high degree of interest to the people of Montana during the important period of progressive change documented “In the Crucible of Change.” Jerry Loendorf, who served as Chair of the Legislative Committee at the 1972 Montana Constitutional Convention, received a BA from Carroll College in 1961 and a JD from the University of Montana Law School in 1964. Upon graduation he served two years as a law clerk for the Montana Supreme Court after which he was for 34 years a partner in the law firm of Harrison, Loendorf & Posten, Duncan. In addition to being a delegate to the Constitutional Convention, Jerry served on the Board of Labor Appeals from 2000 to 2004. He was designated a Montana Special Assistant Attorney General to represent the state in federal court on the challenge to the results of the ratification election of Montana's Constitution in 1972. Jerry served on the Carroll College Board of Directors in the late 1960s and then again as a member of the Board of Trustees of Carroll College from 2001 to 2009. He has served on the Board of Directors of the Rocky Mountain Development Council since 1970 and was on the board of the Helena YMCA from 1981 to 1987. He also served on the board of the Good Samaritan Ministries from 2009 to 2014. On the business side, Jerry was on the Board of Directors of Valley Bank to Helena from 1980 to 2005. He is a member of the American Bar Association, State Bar of Montana, the First Judicial District Bar Association, and the Montana Trial Lawyers Association. Carroll College awarded Jerry the Warren Nelson Award 1994 and the Insignias Award in 2007. At Carroll College, Jerry has funded the following three scholarship endowments: George C and Helen T Loendorf, Gary Turcott, and Fr. William Greytek. Arlyne Reichert, Great Falls Delegate to the Constitutional Convention and former State Legislator, was born in Buffalo, NY in 1926 and attended University of Buffalo in conjunction with Cadet Nurses Training during WWII. She married a Montanan in Great Falls in 1945 and was widowed in 1968. She is mother of five, grandmother of seven, great-grandmother of four. Arlyne was employed by McLaughlin Research Institute in Great Falls for 23 years, serving as Technical Editor of Transplantation Journal in 1967, retiring as Assistant Director in 1989. In addition to being a state legislator (1979 Session) and a delegate to the 1972 Montana Constitutional Convention, she has filled many public roles, including Cascade County Study Commissioner (1974), MT Comprehensive Health Council, US Civil Rights Commission MT Advisory Committee, MT Capitol Restoration Committee, and Great Falls Public Library Trustee. Arlyne has engaged in many non-profit activities including League of Women Voters (State & Local Board Officer – from where her interest in the MT Constitutional change developed), Great Falls Public Radio Association (President & Founder), American Cancer Society (President Great Falls Chapter), Chair of MT Rhodes Scholarship Committee, and Council Member of the National Civic League. She also served a while as a Television Legislative Reporter. Arlyne has been recipient of numerous awards, the National Distinguished Citizens Award from the National Municipal League, two Women of Achievement Awards from Business & Professional Women, the Salute to Women Award by YWCA, Heritage Preservation Award from Cascade County Historical Society and the State of Montana, and the Heroes Award from Humanities Montana. She remains active, serving as Secretary-Treasurer of Preservation Cascade, Inc., and as Board Member of the McLaughlin Research Institute. Her current passion is applied to the preservation/saving of the historic 10th Street Bridge that crosses the Missouri River in Great Falls. Rich Bechtel of Helena was born in Napa, California in 1945 and grew up as an Air Force brat living in such places as Bitberg, Germany, Tripoli, Libya, and Sevilla, Spain. He graduated from Glasgow High School and the University of Montana. Rich was a graduate assistant for noted Montana History professor Professor K. Ross Toole, but dropped out of graduate school to pursue a real life in Montana politics and government. Rich has had a long, varied and colorful career in the public arena. He currently is the Director of the Office of Taxpayer Assistance & Public Outreach for MT’s Department of Revenue. He previously held two positions with the National Wildlife Federation in Washington, DC (Sr. Legislative Representative [1989-91] and Sr. Legislative Representative for Wildlife Policy [2004-2006]). While in Washington DC, he also was Assistant for Senator Lee Metcalf (D-MT), 1974-1976; Federal-State Coordinator for State of Montana, 1976-1989; Director of the Western Governors’ Association Washington Office, 1991-2000; and Director of Federal Affairs for Governor Kitzhaber of Oregon, 2001- 2003. Earlier in Montana Government, between 1971 and 1974, Rich was Research Analyst for MT Blue Ribbon Commission on Postsecondary Education, Legislative Consultant and Bill Drafter for MT Legislative Council, Research Analyst for the MT Constitutional Convention Commission where he provided original research on legislatures, as well as Researcher/Staff for the MT Constitutional Convention Legislative Committee, from where he drafted the various provisions of the Legislative Article and the majority and minority reports on behalf of the Committee members. Rich has represented Montana’s Governor on a trade and cultural mission to Republic of China and participated in US-German Acid Rain Committee sessions in Germany and with European Economic Community environmental officials in Belgium. He is married to Yvonne Seng (Ph.D.) - T’ai Chi apprentice; author and birder.

Mineralogical and geochemical data from five lake sediment cores of Lake Donggi Cona

Sediments of Lake Donggi Cona on the northeastern Tibetan Plateau were studied to infer changes in the lacustrine depositional environment, related to climatic and non-climatic changes during the last 19 kyr. The lake today fills a 30 X 8 km big and 95 m deep tectonic basin, associated with the Kunlun Fault. The study was conducted on a sediment-core transect through the lake basin, in order to gain a complete picture of spatiotemporal environmental change. The recovered sediments are partly finely laminated and are composed of calcareous muds with variable amounts of carbonate micrite, organic matter, detrital silt and clay. On the basis of sedimentological, geochemical, and mineralogical data up to five lithological units (LU) can be distinguished that document distinct stages in the development of the lake system. The onset of the lowermost LU with lacustrine muds above basal sands indicates that lake level was at least 39 m below the present level and started to rise after 19 ka, possibly in response to regional deglaciation. At this time, the lacustrine environment was characterized by detrital sediment influx and the deposition of siliciclastic sediment. In two sediment cores, upward grain-size coarsening documents a lake-level fall after 13 cal ka BP, possibly associated with the late-glacial Younger Dryas stadial. From 11.5 to 4.3 cal ka BP, grainsize fining in sediment cores from the profundal coring sites and the onset of lacustrine deposition at a litoral core site (2m water depth) in a recent marginal bay of Donggi Cona document lake-level rise during the early tomid-Holocene to at least modern level. In addition, high biological productivity and pronounced precipitation of carbonate micrites are consistent with warm and moist climate conditions related to an enhanced influence of summer monsoon. At 4.3 cal ka BP the lake system shifted from an aragonite- to a calcite-dominated system, indicating a change towards a fully open hydrological lake system. The younger clay-rich sediments are moreover non-laminated and lack any diagenetic sulphides, pointing to fully ventilated conditions, and the prevailing absence of lake stratification. This turning point in lake history could imply either a threshold response to insolation-forced climate cooling or a response to a non-climatic trigger, such as an erosional event or a tectonic pulse that induced a strong earthquake, which is difficult to decide from our data base.

Echo-delay resolution in sonar images of the big brown bat, Eptesicus fuscus

Echolocating big brown bats (Eptesicus fuscus) broadcast ultrasonic frequency-modulated (FM) biosonar sounds (20–100 kHz frequencies; 10–50 μs periods) and perceive target range from echo delay. Knowing the acuity for delay resolution is essential to understand how bats process echoes because they perceive target shape and texture from the delay separation of multiple reflections. Bats can separately perceive the delays of two concurrent electronically generated echoes arriving as little as 2 μs apart, thus resolving reflecting points as close together as 0.3 mm in range (two-point threshold). This two-point resolution is roughly five times smaller than the shortest periods in the bat’s sounds. Because the bat’s broadcasts are 2,000–4,500 μs long, the echoes themselves overlap and interfere with each other, to merge together into a single sound whose spectrum is shaped by their mutual interference depending on the size of the time separation. To separately perceive the delays of overlapping echoes, the bat has to recover information about their very small delay separation that was transferred into the spectrum when the two echoes interfered with each other, thus explicitly reconstructing the range profile of targets from the echo spectrum. However, the bat’s 2-μs resolution limit is so short that the available spectral cues are extremely limited. Resolution of delay seems overly sharp just for interception of flying insects, which suggests that the bat’s biosonar images are of higher quality to suit a wider variety of orientation tasks, and that biosonar echo processing is correspondingly more sophisticated than has been suspected.

Geomorphic Impacts of the 2013 Colorado Front Range Flood on Black Canyon Creek and North Fork Big Thompson River

In September 2013, the Colorado Front Range experienced a five-day storm that brought record-breaking precipitation to the region. As a consequence, many Front Range streams experienced flooding, leading to erosion, debris flows, bank failures and channel incision. I compare the effects that debris flows and flooding have on the channel bar frequency, frequency and location of wood accumulation, and on the shape and size of the channel along two flood impacted reaches located near Estes Park and Glen Haven, Colorado within Rocky Mountain National Park and Arapaho-Roosevelt National Forest: Black Canyon Creek (BCC) and North Fork Big Thompson River (NFBT). The primary difference between the two study areas is that BCC was inundated by multiple debris flows, whereas NFBT only experienced flooding. Fieldwork consisted of recording location and size of large wood and channel bars and surveying reaches to produce cross-sections. Additional observations were made on bank failures in NFBT and the presence of boulders in channel bars in BCC to determine sediment source. The debris flow acted to scour and incise BCC causing long-term alteration. The post-flood channel cross-sectional area is as much as 7 to 23 times larger than the pre-flood channel, caused by the erosion of the channel bed to bedrock and the elimination of riparian vegetation. Large wood was forced out of the stream channel and deposited outside of the bankfull channel. Flooding in NFBT caused bank erosion and widening that contributed sediment to channel bars, but accomplished little stream-bed scour. As a result, there was relatively little damage to mid-channel and riparian vegetation, and most large wood remained within the wetted channel.

Jazz band arranging : original big band arrangements

This paper examines five big band arrangements written during a period of two semesters from 1998-1999. I will provide an overview and performance considerations for each arrangement. Each arrangement uses common conventions such as unison lines, octave doubling, four and five part voicings, found in closed, semi-open, and open position. Approach techniques include diatonic, dominant, diminished, chromatic, and parallel. Choice was based primarily on two considerations: desired texture and the best voice leading options identified to provide each part with a swinging line and maintain melodic integrity. Other conventions applied include chord substitution, upper structure triads, and altered and diminished scales to provide harmonic contrast and color. Each arrangement supplied new challenges and the tunes selected provided the arranger with a diverse experience of styles. The inherent qualities of the melody and harmonic progression of each piece were the primary considerations for selection.

Big Data Analysis in Social Networks : Extracting Food Preferences of Vegans from Twitter

Market research is often conducted through conventional methods such as surveys, focus groups and interviews. But the drawbacks of these methods are that they can be costly and timeconsuming. This study develops a new method, based on a combination of standard techniques like sentiment analysis and normalisation, to conduct market research in a manner that is free and quick. The method can be used in many application-areas, but this study focuses mainly on the veganism market to identify vegan food preferences in the form of a profile. Several food words are identified, along with their distribution between positive and negative sentiments in the profile. Surprisingly, non-vegan foods such as cheese, cake, milk, pizza and chicken dominate the profile, indicating that there is a significant market for vegan-suitable alternatives for such foods. Meanwhile, vegan-suitable foods such as coconut, potato, blueberries, kale and tofu also make strong appearances in the profile. Validation is performed by using the method on Volkswagen vehicle data to identify positive and negative sentiment across five car models. Some results were found to be consistent with sales figures and expert reviews, while others were inconsistent. The reliability of the method is therefore questionable, so the results should be used with caution.

Big Bath and Impairment of Goodwill : A study of the European telecommunications industry

Income decreasing strategies conducted by management could be harmful for various stakeholders. One example is big bath accounting, which could be accomplished in numer- ous ways. This study focus on big baths achieved by recognising impairments of goodwill. Purpose - The purpose of this study is to examine patterns of association between big bath accounting and impairment of goodwill within the telecommunication service industry in Europe. Further, this study aim at contributing to the discussion regarding utilisation of big baths through impairments of goodwill, and takes the perspective of an external stakehold- er. Delimitations - The study is restricted to European telecommunication entities comprised in STOXX Europe 600 Index. Method - This study was conducted using a hybrid of qualitative and quantitative research strategy with a deductive approach. The five indicators used to identify various big bath behaviours were inspired and derived from theory and previous research. Data from 2009 to 2015 was collected from the companies’ annual reports and websites, and analysed by the help of codification of each fulfilled indicator where 2009 merely served as a compara- tive year for 2010. By the use of a scoreboard the collected data was summarised on an ag- gregated yearly basis as the industry, not the specific companies, were analysed. Empirical findings - The results of this study suggests that big baths are executed among tele- communication companies within Europe. These are conducted simultaneously as impair- ments of goodwill are present, facilitated by earning management. A possible explanation is considered to be the room for interpretation inherent in IAS 36, enabling goodwill impair- ments to be recognised on managers’ command. Thereby an impairment could be “saved” for better or worse circumstances, or recognised when there exist an opportunity to max- imise (the manager's) wealth in the future. This study reveal the co-occurrence of goodwill impairments and big bath-indications, however a review of causal relationships are not en- abled by the limitations of the chosen method. 

The big four skills: Teachers’ assumptions on measurement of non-native students cognition

The four-skills on tests for young native speakers commonly do not generate correlation incongruency concerning the cognitive strategies frequently reported. Considering the non-native speakers there are parse evidence to determine which tasks are important to assess properly the cognitive and academic language proficiency (Cummins, 1980; 2012). Research questions: It is of high probability that young students with origin in immigration significantly differ on their communication strategies and skills in a second language processing context (1); attached to this first assumption, it is supposed that teachers significantly differ depending on their scientific area and previous training (2). Purpose: This study intends to examine whether school teachers (K-12) as having different origin in scientific domain of teaching and training perceive differently an adapted four-skills scale, in European Portuguese. Research methods: 77 teachers of five areas scientific areas, mean of teaching year service = 32 (SD= 2,7), 57 males and 46 females (from basic and high school levels). Main findings: ANOVA (Effect size and Post-hoc Tukey tests) and linear regression analysis (stepwise method) revealed statistically significant differences among teachers of different areas, mainly between language teachers and science teachers. Language teachers perceive more accurately tasks in a multiple manner to the broad skills that require to be measured in non-native students. Conclusion: If teachers perceive differently the importance of the big-four tasks, there would be incongruence on skills measurement that teachers select for immigrant puppils. Non-balanced tasks and the teachers’ perceptions on evaluation and toward competence of students would likely determine limitations for academic and cognitive development of non-native students. Furthermore, results showed sufficient evidence to conclude that tasks are perceived differently by teachers toward importance of specific skills subareas. Reading skills are best considered compared to oral comphreension skills in non-native students.

Why the “Big Deal” continues to persist

The advantages of bundling e-journals together into publisher collections include increased access to information for the subscribing institution’s clients, purchasing cost-effectiveness and streamlined workflows. Whilst cataloguing a consortial e-journal collection has its advantages, there are also various pitfalls and the author outlines efforts by the CAUL (Council of Australian University Libraries) Consortium libraries to further streamline this process, working in conjunction with major publishers. Despite the advantages that publisher collections provide, pressures to unbundle existing packages continue to build, fuelled by an ever-increasing selection of available electronic resources; decreases in, and competing demands upon, library budgets; the impact of currency fluctuations; and poor usage for an alarmingly high proportion of collection titles. Consortial perspectives on bundling and unbundling titles are discussed, including options for managing the addition of new titles to the bundle and why customising consortial collections currently does not work. Unbundling analyses carried out at Queensland University of Technology during 2006 to 2008 prior to the renewal of several major publisher collections are presented as further case studies which illustrate why the “big deal” continues to persist.
