    Optical dating has been applied to sediments preserved in Little Sippewissett Marsh, Massachusetts, USA, which are associated with overwashing of the beach barrier during hurricane strikes on the coast. The aims were to determine the hurricane landfall frequency, and make comparisons with independent age control and the historical record. Written sources of hurricane activity along the American east coast are only considered reliable back to the mid 19th century, but the sedimentary record is potentially much longer. Optical dating was applied to quartz grains extracted from thirteen samples within a sediment core from the salt-marsh. Variability in the luminescence characteristics between aliquots was observed and ~ 33% of the measured aliquots were discarded based upon the ratio of the fast component to the medium component. The majority of the samples gave normal dose distributions implying homogeneous resetting of the luminescence signal at the time of deposition, but three of the samples required application of the minimum age model (MAM). Ages ranging between 20 ± 2 and 594 ± 38 years were obtained and are broadly in agreement with independent chronologies, thus demonstrating the potential of optical dating in this setting. The hurricane record based upon optical dating extends approximately 300 years further back in time than the official National Oceanic Atmospheric Administration (NOAA) record. The localised nature of hurricane landfalls means that it will be necessary to collect multiple cores from a number of different sites in order to build up a complete hurricane record for this part of the coast.

    Science.gov (United States)

    Butman, Bradford

    Construction of a new treatment plant and outfall to clean up Boston Harbor is currently one of the world's largest public works projects, costing about $4 billion. There is concern about the long-term impact of contaminants on Massachusetts Bay and adjacent Gulf of Maine because these areas are used extensively for transportation, recreation, fishing, and tourism, as well as waste disposal. Public concern also focuses on Stellwagen Bank, located on the eastern side of Massachusetts Bay, which is an important habitat for endangered whales. Contaminants reach Massachusetts Bay not only from Boston Harbor, but from other coastal communities on the Gulf of Maine, as well as from the atmosphere. Knowledge of the pathways, mechanisms, and rates at which pollutants are transported throughout these coastal environments is needed to address a wide range of management questions.

    2013-01-01

    The luminescence techniques have evolved over the last 40 years to a powerful dating instrument in archaeology and geoscience. Depending on how the luminescence is stimulated, one distinguishes the phenomena of thermoluminescence (TL), optically stimulated luminescence (OSL) and infrared stimulated luminescence (IRSL). Each of these phenomena has its specific potential for dating various archaeological materials in the time range from medieval back to palaeolithic periods, or, speaking in geological terms, for dating of Holocene and late Pleistocene objects. The OSL and IRSL techniques are sometimes treated together as 'optical dating'. The luminescence techniques differ from other major dating techniques, such as 14 C, essentially by their applicability to inorganic materials, their wide age-range from about 100 years to more than 100,000 years and the kind of datable events which are the last exposure to heat or to light.

    2017-01-01

    Since the discovery of natural radioactivity in uranium, in the last decade of the nineteenth century, the nuclear property of radioactive decay of radionuclides at immutable rates has been effectively utilized in dating of varieties of naturally occurring geological matrices and the organisms which constantly replenish their 14 C supply through respiration when alive on earth. During the period, applications of radiometric dating techniques have been extensively diversified and have enabled the geologists to indicate the absolute time scales of geological formations and the evolution of the solar system, the earth, meteorites, lunar rocks, etc. and the archaeologists to record the facts of history of several important events like dinosaur era, Iceman, the Shroud in Turin and many other ancient artefacts. In the development of dating methods, varieties of naturally occurring radio-isotopic systems with favorable half-lives ranging from about 10 years to over 100 billion years have been used as radiometric clocks.

    Purpose This study examines worksite health promotion (WHP) and occupational health and safety (OHS) activities by Massachusetts employers, and the extent to which workplaces with programming in one domain were more likely to have the other as well. Design In 2008, the Massachusetts Department of Public Health surveyed a stratified sample of Massachusetts worksites. Setting A mailed questionnaire to be completed by workplace representatives. Subjects Massachusetts worksites returning the questionnaire. Measures Questionnaire items about worksite characteristics, WHP, and some OHS practices. Analysis We scored levels of WHP and OHS activity; examined the relationship between activities in the two domains by employer characteristics; and assessed self-reported coordination between them. Results The 890 responding worksites had higher scores for OHS (mean = 48% of practices, SD = 24%) than WHP (mean = 20%, SD = 12%). The difference between these scores varied by a factor of two across industry sectors and was smallest for workforces of 100+ employees (p = .001). Employers with no unionized workers reported fewer activities in both domains (p workplaces in Massachusetts were more likely to offer both WHP and OHS programming. Self-reported coordination was somewhat associated with more activity in both domains, although levels of WHP activity varied widely. PMID:23470184

  4. Thermoluminescence dating

    International Nuclear Information System (INIS)

    Price, D.M.

    1999-01-01

    Thermoluminescence (TL) dating of sediments depends upon the acquisition and long term stable storage of TL energy by crystalline minerals contained within a sedimentary unit. This energy is stored in the form of trapped electrons and quartz sand is the most commonly used mineral employed in the dating process. Prior to the final depositional episode it is necessary that any previously acquired TL is removed by exposure to sunlight. After burial the TL begins to build up again at a rate dependent upon the radiation flux delivered by long-lived isotopes of uranium, thorium and potassium. The presence of rubidium and cosmic radiation generally play a lesser but contributory roll, and the total radiation dose delivered to the TL phosphor is modified by the presence of water. The period since deposition is therefore measured by determining the total amount of stored TL energy, the palaeodose (P), and the rate at which this energy is acquired, the annual radiation dose (ARD). TL dating may be applied to eolian, fluvial, coastal and in some cases, marine sediments. the technique is also successfully applied to volcanic materials and to a certain extent to archeological specimens

  5. Cranberry flowering times and climate change in southern Massachusetts

    2014-09-01

    Plants in wild and agricultural settings are being affected by the warmer temperatures associated with climate change. Here we examine the degree to which the iconic New England cranberry, Vaccinium macrocarpon, is exhibiting signs of altered flowering phenology. Using contemporary records from commercial cranberry bogs in southeastern Massachusetts in the United States, we found that cranberry plants are responsive to temperature. Flowering is approximately 2 days earlier for each 1 °C increase in May temperature. We also investigated the relationship between cranberry flowering and flight dates of the bog copper, Lycaena epixanthe—a butterfly dependent upon cranberry plants in its larval stage. Cranberry flowering and bog copper emergence were found to be changing disproportionately over time, suggesting a potential ecological mismatch. The pattern of advanced cranberry flowering over time coupled with increased temperature has implications not only for the relationship between cranberry plants and their insect associates but also for agricultural crops in general and for the commercial cranberry industry.

  14. Medical bankruptcy in Massachusetts: has health reform made a difference?

    Science.gov (United States)

    Himmelstein, David U; Thorne, Deborah; Woolhandler, Steffie

    2011-03-01

    Massachusetts' recent health reform has decreased the number of uninsured, but no study has examined medical bankruptcy rates before and after the reform was implemented. In 2009, we surveyed 199 Massachusetts bankruptcy filers regarding medical antecedents of their financial collapse using the same questions as in a 2007 survey of 2314 debtors nationwide, including 44 in Massachusetts. We designated bankruptcies as "medical" based on debtors' stated reasons for filing, income loss due to illness, and the magnitude of their medical debts. In 2009, illness and medical bills contributed to 52.9% of Massachusetts bankruptcies, versus 59.3% of the bankruptcies in the state in 2007 (P=.44) and 62.1% nationally in 2007 (Pbankruptcy filings in Massachusetts increased 51%, an increase that was somewhat less than the national norm. (The Massachusetts increase was lower than in 54 of the 93 other bankruptcy districts.) Overall, the total number of medical bankruptcies in Massachusetts increased by more than one third during that period. In 2009, 89% of debtors and all their dependents had health insurance at the time of filing, whereas one quarter of bankrupt families had experienced a recent lapse in coverage. Massachusetts' health reform has not decreased the number of medical bankruptcies, although the medical bankruptcy rate in the state was lower than the national rate both before and after the reform.

    Veterans Health Administration (VA) operates the largest integrated health system in the nation. The Affordable Care Act (ACA) does not require any changes to VA, but the individual mandate and expanded health insurance options may change veterans' preferences for coverage. We examined the impact of healthcare reform in Massachusetts, which also included these policy changes, on veterans' enrollment in VA, private insurance, and Medicaid. Massachusetts' healthcare reform in June 2006 served as a natural experiment. Using data from the 2004-2013 Current Population Surveys, we examined enrollment in VA, private insurance, and Medicaid, comparing veterans residing in Massachusetts with veterans residing in neighboring New England states that did not undergo health reform. We estimated the probability of being enrolled in VA, private insurance, and Medicaid before and after healthcare reform, using multivariate probit models while adjusting for individual characteristics. Using a difference-in-difference approach, we compared pre-post changes in enrollment probability among Massachusetts and non-Massachusetts veterans, respectively. Compared with other New England veterans, Massachusetts veterans decreased their enrollment in VA and private insurance by 0.2 (P = .857) and 0.9 (P = .666) percentage points, respectively, following health reform. In contrast, Medicaid enrollment increased by 2.5 percentage points (P = .038). Healthcare reform in Massachusetts was associated with greater Medicaid enrollment, but was not significantly associated with VA and private insurance enrollment. Our results are significant for informing VA fiscal planning in the post ACA era.

  16. Adolescent dating violence and date rape.

    Science.gov (United States)

    Rickert, Vaughn I; Vaughan, Roger D; Wiemann, Constance M

    2002-10-01

    In this review we intend to examine recent literature on dating violence among female adolescents, including prevalence, risk factors, sequelae, screening practices, and potential interventions. Dating violence is perpetrated by both males and females and occurs frequently within heterosexual dating relationships. Attitudes toward physical aggression, including those of peers, and abuse by siblings predict later violence as victim and perpetrator. Victims of childhood or dating violence may be at greater risk of developing eating disorders. New strategies and measures to promote screening are available. Dating violence occurs among all groups of adolescents with common and unique risk factors for dating violence found across adolescents grouped by race/ethnicity, sex, and prior victimization. Efforts to decrease dating violence should (1) increase the use of screening tools that measure victimization as well as attitudes and contextual parameters that promote dating violence; (2) increase self-efficacy to negotiate safer sex; (3) reduce the use/abuse of alcohol and other drugs that facilitate dating violence; and (4) eliminate the influence of negative peer behavior. Interventions to prevent dating violence will likely also reduce rates of unintended pregnancies, HIV, and sexually transmitted diseases among adolescents.

    Davis, S.H.

    1982-01-01

    The accident at Three Mile Island affected the attitudes not only of residents in the immediate vicinity of Middletown, Pennsylvania, but also of citizens in other communities that hosted nuclear plants. This chapter describes the evolution of public attitudes toward nuclear power in the town of Plymouth, Massachusetts, from the time plans for the construction of the Pilgrim-1 plant were announced in 1967 until after the accident at Three Mile Island in March 1979. The ideas developed here arose from three summers of anthropological fieldwork in Plymouth. This study includes a review of the social science literature on nuclear-power plant sitings, interviews with town officials and utility-company representatives, a content analysis of articles in the local newspaper, collection of demographic and other social statistics, attendance at public hearings and town meetings, and interviews with Plymouth citizens

    Although the responses of living organisms to climate change are being widely investigated, little attention has been given to such effects late in the growing season. We studied the late-season flight times of 20 species of butterflies in a geographically limited region, the state of Massachusetts in the USA, by examining change in dates of flight over a 22-year period and in response to average monthly temperature and precipitation. By analyzing the last 10% of each year's observations reported by observers of the Massachusetts Butterfly Club, we found that seven species remain in flight significantly later into the fall than they did two decades earlier, while two species show reduced late-season flight. Life history characteristics of the species, particularly voltinism and average fall flight dates, influenced whether warmer fall months led to increases or decreases in fall flight. Warmer Novembers often led to later fall flight, and wetter Augusts usually extended fall flight. These results document the effects of climate on late-season flight times of butterflies, add to an understanding of how warmer autumn conditions alter the phenology of different butterfly species, and show the usefulness of citizen science data.

    2011-01-01

    The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation, Massachusetts Department of Environmental Protection, and the Massachusetts Department of Fish and Game, conducted an investigation of fish assemblages in small- to medium-sized Massachusetts streams. The objective of this study was to determine relations between fish-assemblage characteristics and anthropogenic factors, including impervious cover and estimated flow alteration, relative to the effects of environmental factors, including physical-basin characteristics and land use. The results of this investigation supersede those of a preliminary analysis published in 2010. Fish data were obtained for 669 fish-sampling sites from the Massachusetts Division of Fisheries and Wildlife fish-community database. A review of the literature was used to select fish metrics - species richness, abundance of individual species, and abundances of species grouped on life history traits - responsive to flow alteration. The contributing areas to the fish-sampling sites were delineated and used with a geographic information system to determine a set of environmental and anthropogenic factors that were tested for use as explanatory variables in regression models. Reported and estimated withdrawals and return flows were used together with simulated unaltered streamflows to estimate altered streamflows and indicators of flow alteration for each fish-sampling site. Altered streamflows and indicators of flow alteration were calculated on the basis of methods developed in a previous U.S. Geological Survey study in which unaltered daily streamflows were simulated for a 44-year period (water years 1961-2004), and streamflow alterations were estimated by use of water-withdrawal and wastewater-return data previously reported to the State for the 2000-04 period and estimated domestic-well withdrawals and septic-system discharges. A variable selection process, conducted using principal

    Insurance impacts access to therapeutic options, yet little is known about how healthcare reform might change the pattern of surgical admissions. We compared rates of emergent admissions and outcomes after colectomy before and after reform in Massachusetts with a nationwide control group. This study is a retrospective cohort analysis in a natural experiment. Prereform was defined as hospital discharge from 2002 through the second quarter of 2006 and postreform from the third quarter of 2006 through 2012. Categorical variables were compared by χ. Piecewise functions were used to test the effect of healthcare reform on the rate of emergent surgeries. The study included acute care hospitals in the Massachusetts Healthcare Cost and Utilization Project State Inpatient Database (2002-2012) and the Nationwide Inpatient Sample (2002-2011). Patients aged 18 to 64 years with public or no insurance who underwent inpatient colectomy (via International Classification of Diseases, Ninth Revision, Clinical Modification procedural code) were included and patients with Medicare were excluded. Massachusetts health care reform was the study intervention. We measured the rate of emergent colectomy, complications, and mortality. The unadjusted rate of emergent colectomies was lower in Massachusetts after reform but did not change nationally over the same time period. For emergent surgeries in Massachusetts, a piecewise model with an inflection point (peak) in the third quarter of 2006, coinciding with implementation of healthcare reform in Massachusetts, had a lower mean squared error than a linear model. In comparison, the national rate of emergent surgeries demonstrated no change in pattern. Postreform, length of stay decreased by 1 day in Massachusetts; however, there were no significant improvements in other outcomes. The study was limited by its retrospective design and unadjusted analysis. There was a unique and sustained decline in the rate of emergent colon resection among

  15. [Book review] Massachusetts breeding bird atlas

    Science.gov (United States)

    Robbins, Chandler S.

    2005-01-01

    A glance at the dust jacket of this handsome volume drives home the conservation message that breeding bird atlases are designed to promote—that bird populations are changing over vast areas and, unless we become aware of changes in status and take remedial action, some species will disappear from our neighborhoods and even our county or state. A case in point involves the closely related Golden-winged Warbler (Vermivora chrysoptera) and Blue- winged Warbler (Vermivora pinus). The males are shown in the atlas with their breeding distribution maps. When I was an active birder in the Boston suburbs in the 1930s, the Golden-winged Warbler was a common breeder and it was a treat to find a Blue-winged Warbler. The atlas map 40 years later (1974–1979) shows only five confirmed records statewide for the Golden-winged Warbler, compared with 73 for the Blue-winged Warbler, and the Golden-winged Warbler is now listed as endangered by the Massachusetts Division of Fisheries and Wildlife. Nationally, it is a species of management concern.

  16. Massachusetts Large Blade Test Facility Final Report

    Rahul Yarala; Rob Priore

    2011-09-02

    Project Objective: The Massachusetts Clean Energy Center (CEC) will design, construct, and ultimately have responsibility for the operation of the Large Wind Turbine Blade Test Facility, which is an advanced blade testing facility capable of testing wind turbine blades up to at least 90 meters in length on three test stands. Background: Wind turbine blade testing is required to meet international design standards, and is a critical factor in maintaining high levels of reliability and mitigating the technical and financial risk of deploying massproduced wind turbine models. Testing is also needed to identify specific blade design issues that may contribute to reduced wind turbine reliability and performance. Testing is also required to optimize aerodynamics, structural performance, encourage new technologies and materials development making wind even more competitive. The objective of this project is to accelerate the design and construction of a large wind blade testing facility capable of testing blades with minimum queue times at a reasonable cost. This testing facility will encourage and provide the opportunity for the U.S wind industry to conduct more rigorous testing of blades to improve wind turbine reliability.

    2013-12-01

    Massachusetts enacted health care reform in 2006 to expand insurance coverage and improve access to health care. The objective of our study was to compare trends in health status and the use of ambulatory health services before and after the implementation of health reform in Massachusetts relative to that in other New England states. We used a quasi-experimental design with data from the Behavioral Risk Factor Surveillance System from 2001 to 2011 to compare trends associated with health reform in Massachusetts relative to that in other New England states. We compared self-reported health and the use of preventive services using multivariate logistic regression with difference-in-differences analysis to account for temporal trends. We estimated predicted probabilities and changes in these probabilities to gauge the differential effects between Massachusetts and other New England states. Finally, we conducted subgroup analysis to assess the differential changes by income and race/ethnicity. The sample included 345,211 adults aged eighteen to sixty-four. In comparing the periods before and after health care reform relative to those in other New England states, we found that Massachusetts residents reported greater improvements in general health (1.7%), physical health (1.3%), and mental health (1.5%). Massachusetts residents also reported significant relative increases in rates of Pap screening (2.3%), colonoscopy (5.5%), and cholesterol testing (1.4%). Adults in Massachusetts households that earned up to 300% of the federal poverty level gained more in health status than did those above that level, with differential changes ranging from 0.2% to 1.3%. Relative gains in health status were comparable among white, black, and Hispanic residents in Massachusetts. Health care reform in Massachusetts was associated with improved health status and the greater use of some preventive services relative to those in other New England states, particularly among low

  18. Less Truth Than Error: Massachusetts Teacher Tests

    Directory of Open Access Journals (Sweden)

    Walt Haney

    1999-02-01

    Full Text Available Scores on the Massachusetts Teacher Tests of reading and writing are highly unreliable. The tests' margin of error is close to double to triple the range found on well-developed tests. A person retaking the MTT several times could have huge fluctuations in their scores even if their skill level did not change significantly. In fact, the 9 to 17 point margin of error calculated for the tests represents more than 10 percent of the grading scale (assumed to be 0 to 100. The large margin of error means there is both a high false-pass rate and a high false-failure rate. For example, a person who received a score of 72 on the writing test could have scored an 89 or a 55 simply because of the unreliability of the test. Since adults' reading and writing skills do not change a great deal over several months, this range of scores on the same test should not be possible. While this test is being touted as an accurate assessment of a person's fitness to be a teacher, one would expect the scores to accurately reflect a test-taker's verbal ability level. In addition to the large margin of error, the MTT contain questionable content that make them poor tools for measuring test-takers' reading and writing skills. The content and lack of correlation between the reading and writing scores reduces the meaningfulness, or validity, of the tests. The validity is affected not just by the content, but by a host of factors, such as the conditions under which tests were administered and how they were scored. Interviews with a small sample of test-takers confirmed published reports concerning problems with the content and administration.

  19. Managing low-level radioactive waste in Massachusetts. Final report

    Bander, S.R.; Goldstein, M.E.

    1983-12-01

    As one of the country's largest generators of low-level radioactive waste, Massachusetts has begun independently seeking solutions to the questions surrounding low-level waste management issues. The Massachusetts Department of Public Health, Radiation Control Program, obtained funding from the U.S. Department ofEnergy through EG and G, Idaho, Inc. to develop a low-level waste management strategy for the Commonwealth. The Working Group was made up of individuals from various waste generating industries, environmental and public interest groups, medical and academic institutions, and affected state agencies. This final report document contains the following staff project reports: Proposed Low-Level Radioactive Waste Management Plan for The Commonwealth of Massachusetts, February 1983 and Low-Level Radioactive Waste Management in Massachusetts - Actions to be Considered for Implementation in 1984-1986, December 1983. These two staff reports represent the completion of the Massachusetts Low-Level Radioactive Waste Management Project. The first report provides some of the background material to the issues and some of the alternative courses of action which can be considered by state policy-makers. The second report provides the next phase in the process by delineating specific steps which may be taken before 1986 in order to address the low-level waste problem, and the estimated amount of time needed to complete each step

  2. Case study: Massachusetts Department of Public Health's Southeastern Massachusetts health study on leukemia around Pilgrim Nuclear Power Station: Who won?

    International Nuclear Information System (INIS)

    Flanagan, Anita

    1993-01-01

    In October 1990, the Massachusetts Department of Public Health released their Southeastern Massachusetts health study. This is a study of leukemia incidence in 22 towns around Pilgrim NPP, for the period 1978 through 1986. Pilgrim Station had been returned to operation following a 3 year outage, from 1986-1989. During this period, some $300 million in capital outlay was invested by Boston Edison in upgrading safety systems and installing the so-Called Three Mile Island upgrades. A copy of the peer review panel report is attached to this paper. Because of the interest in the Southeastern Massachusetts Health Study in Europe. There are three major points the Panel made which can summarized: 1. No excess of leukemia was found around Pilgrim Station. 2. The Southeastern Massachusetts Health Study over-predicted by a factor of 90 the number of leukemia cases attributable to plant operation. 3. The Southeastern Massachusetts Health Study failed to account for exposure to natural background radiation, which represents far larger biological exposure than plant Operation. Given All Of This, One Might Ask Why Didn't Common Sense Prevail In The Beginning? One Answer Might Be The Energy Of The Media In Pursuing The Story And Playing It Up No Matter What. Another Answer Might Be That The Original Study Purported To Show 'What Everyone Knows'. No One Really Stopped To Question Whether The Study Was Politically Motivated, Given That The Division of Environmental Health's Budget Had Been Cut

  4. Massachusetts reform plus President Bush's tax credits: a national model?

    Science.gov (United States)

    Etheredge, Lynn M

    2006-01-01

    The Massachusetts health reform offers an important opportunity for a new federal-state strategy to cover the uninsured. President George Bush's proposed health insurance tax credits could be added to the Massachusetts health reform. The combined plan would include Medicaid expansions; offer workers affordable coverage through competitive insurance markets; and provide federal, state, employer, and individual financing. Many other states might be interested in similar federal-state partnerships for the forty-five million uninsured Americans. Ending the national impasse on coverage needs this kind of bold initiative.

    2010-08-01

    Full Text Available As states across the country struggle to increase local development of renewable energy, policymakers are turning to innovative program designs to meet their renewable electricity targets. Massachusetts recently adopted a unique, auction-based price support mechanism for the solar portion of its renewable portfolio standard. During the program development process, the Massachusetts Department of Energy Resources (DOER used system dynamics to simulate potential solar renewable energy certificate market conditions under the proposed regulations. The modeling exercise resulted in several program design changes that will lead to a more stable certificate market. System dynamics can be a useful tool for developing and improving sustainability programs.

    The date of the Crucifixion has been debated for many years, but there has been no agreement on the year nor the day. Astronomical calculations have now been used to reconstruct the Jewish calendar in the first century AD and to date a lunar eclipse that biblical and other references suggest followed the Crucifixion. The evidence points to Friday 3 April AD 33 as the date when Jesus Christ died.

    When dating unburnt bone, bone collagen, the organic fraction of the bone, is used. Collagen does not survive the heat of the cremation pyre, so dating of cremated bone has been considered impossible. Structural carbonate in the mineral fraction of the bone, however, survives the cremation process. We developed a method of dating cremated bone by accelerator mass spectrometry (AMS), using this carbonate fraction. Here we present results for a variety of prehistoric sites and ages, showing a r...

    Testing of the technical feasibility of radurization of fresh dates was attempted. In addition preliminary studies were carried out to investigate the applicability of gamma rays to date syrup manufacture. The varieties Zahdi, Lelwi and Tabarzel were studied at different stages of ripening. The eating quality of fresh dates was not affected significantly by irradiation even with doses of 270 and 540 krad. The duration of the softening process, after-ripening, of dates was prolonged by low doses of 10-30 krad in the majority of the experimental batches. The time period of after-ripening was reduced with 270 krad, as well as with 540 krad as a result of shortening of the induction period, i.e. the time after which the date begins to soften. The microbial spoilage of khalaal Lelwi dates was considerably reduced by irradiation with doses above 90 krad. The dibis yield of fully rutab dates was highly increased by the radiation doses of 375 to 2000 krad. The darkness and viable cell count of dibis pressed from irradiated dates were significantly lower than that of untreated dates. (F.J.)

    Purpose: The aim of this qualitative, phenomenological study was to explore the attitudes and perceptions of public health dental hygienists on providing preventive care to underserved populations in Massachusetts. Methods: Non-probability purposive sampling was used for initial participant recruitment, and snowball sampling occurred thereafter. Data collection occurred through semi-structured interviews. Qualitative analysis was conducted using Pitney and Parker's eight-step CREATIVE process. Results: Data saturation occurred with 10 participants (n=10), one-third of the public health dental hygienists who are practicing in Massachusetts. The majority of practice settings included school-based programs (70%), while programs for children with special needs (10%) were the least common. Two major themes emerged from the data; (a) the opportunity to be an oral health change agent and (b) barriers to practice. Six subcategories emerged from the data and are reviewed within the context of their associated themes. Additionally, career satisfaction emerged as an unintended theme, and was reported as the driving force for the majority of participants. Conclusion: This study revealed a better understanding of the public health dental hygiene workforce model in Massachusetts. Public health dental hygienists in Massachusetts perceive themselves as change agents within the health care profession, and although barriers to practice are plentiful, these oral health care professionals are committed to improving access to dental care.

  16. Luminescence dating in archaeology

    International Nuclear Information System (INIS)

    Wintle, A.G.

    2001-01-01

    Thermoluminescence (TL) dating is routinely applied to burnt lithic material. Simple fires are capable of enabling stones weighing a few hundred grams to reach 450 o C, thus zeroing the TL signal. TL dates have been obtained for Upper and Lower Paleolithic sites in Europe and the Near East. TL dating continues to be used for dating pottery and for authentification of ceramic works of art. Some recent studies report the use of optically stimulated luminescence (OSL) (also know as photoluminescence) for dating very small samples of quartz, e.g. from small pieces of pottery or frm metallurgical slag The major recent advance has been in the development of a reliable laboratory procedure for using the OSL signal from quartz to obtain the past radiation exposure. The quartz OSL signal is extremely sensitive to light and is reduced to a negligible level on exposure to direct sunlight for radionuclides during burial, signal to date san.sized quartz grains extracted from sediments, The OSL signal is stimulated by 470 nm light from emitting diodes and the detected using flirters centred on 340 nm A similar signal can be obtained from feldspar grain when are exposed to infrared wavelengths around 880 nm. The infrared stimulated luminescence (IRSL) signals is also rapidly depleted by exposure to sunlight, and dating of colluvial deposits from archaeological sites has been reported

    Scientific methods of dating, born less than thirty years ago, have recently improved tremendously. First the dating principles will be given; then it will be explained how, through natural radioactivity, we can have access to the age of an event or an object; the case of radiocarbon will be especially emphasized. The principle of relative methods such as thermoluminescence or paleomagnetism will also be shortly given. What is the use for dating. The fields of its application are numerous; through these methods, relatively precise ages can be given to the major events which have been keys in the history of universe, life and man; thus, dating is a useful scientific tool in astrophysics, geology, biology, anthropology and archeology. Even if certain ages are still subject to controversies, we can say that these methods have confirmed evolution's continuity, be it on a cosmic, biologic or human scale, where ages are measured in billions, millions or thousands of years respectively [fr

  2. Dating fossil opal phytoliths

    International Nuclear Information System (INIS)

    Lentfer, C.; Boyd, B.; Torrence, R.

    1999-01-01

    Full text: Opal phytoliths are microscopic silica bodies formed by the precipitation of hydrated silica dioxide (SiO 2 nH 2 0) in, around and between cell walls. They are relatively resistant to degradation in most environments and thus, can occur in large quantities in palaeosediments. Consequently, they are valuable tools for environmental reconstruction. Furthermore, phytoliths are often the only recoverable organic material in well oxidised sediments, the occluded carbon provides the opportunity for dating sediment whose ages have previously been difficult to determine, and thus, increase the potential for fine resolution determination of environmental change. This poster describes the results of an investigation assessing the viability of AMS radiocarbon dating of fossil phytolith inclusions using samples from Garua Island, West New Britain, PNG. Thirteen phytolith samples, isolated from sediments previously dated using tephrastratigraphy and C14 dating of macroremains of nutshells and wood charcoal, were used in the analysis. As a control measure, thirteen parallel samples of microscopic charcoal were also dated using AMS. The results show that the AMS dates for the microscopic charcoal samples are consistent with ages anticipated from the other dating methods, for all but one sample. However, the dates for eight of the thirteen phytolith samples are considerably younger than expected. This bias could be explained by several factors, including downwashing of phytolith through soils, bioturbation, carbon exchange through the siliceous matrix of the phytolith bodies, and contamination from extraneous sources of modern carbon retained in the samples. Research is currently focusing on the investigation of these issues and selected samples are in the process of being retreated with strong oxidising agents to clear contaminants prior to re-dating. Further to this, a full investigation of one profile with a long sequence is underway. High concentrations of

    Chaput, M. A.; Gajewski, K. J.

    2015-12-01

    The Anthropocene has no agreed start date since current suggestions for its beginning range from Pre-Industrial times to the Industrial Revolution, and from the mid-twentieth century to the future. To set the boundary of the Anthropocene in geological time, we must first understand when, how and to what extent humans began altering the Earth system. One aspect of this involves reconstructing the effects of prehistoric human activity on the physical landscape. However, for global reconstructions of land use and land cover change to be more accurately interpreted in the context of human interaction with the landscape, large-scale spatio-temporal demographic changes in prehistoric populations must be known. Estimates of the relative number of prehistoric humans in different regions of the world and at different moments in time are needed. To this end, we analyze a dataset of radiocarbon dates from the Canadian Archaeological Radiocarbon Database (CARD), the Palaeolithic Database of Europe and the AustArch Database of Australia, as well as published dates from South America. This is the first time such a large quantity of dates (approximately 60,000) has been mapped and studied at a global scale. Initial results from the analysis of temporal frequency distributions of calibrated radiocarbon dates, assumed to be proportional to population density, will be discussed. The utility of radiocarbon dates in studies of the Anthropocene will be evaluated and potential links between population density and changes in atmospheric greenhouse gas concentrations, climate, migration patterning and fire frequency coincidence will be considered.

    The goal of this paper is to assess the frequency of depression symptoms among Brazilian immigrants living in Massachusetts, the second largest Brazilian immigrant population in the United States, and to identify correlates of depression. A convenience sample of Brazilian immigrants aged 18 or older residing in Massachusetts was used. Data were collected from December 2013 to March 2014, in the Consulate General of Brazil in Boston and in three religious events, using a structure questionnaire and the Center for Epidemiological Studies Depression Scale (CES-D). Depression symptoms were observed in 35.3% of the respondents, with equal distribution by sex. Correlates of depression were low income, being single, poor English proficiency, and poor self-perception of health. These results suggest a need for community outreach, sensitization, and counseling, in Portuguese and adapted to the culture of Brazilian immigrants.

    A series of maps that describe the distribution and texture of sea-floor sediments and physiographic zones of Massachusetts State waters from Nahant to Salisbury, Massachusetts, including western Massachusetts Bay, have been produced by using high-resolution geophysical data (interferometric and multibeam swath bathymetry, lidar bathymetry, backscatter intensity, and seismic reflection profiles), sediment samples, and bottom photographs. These interpretations are intended to aid statewide efforts to inventory and manage coastal and marine resources, link with existing data interpretations, and provide information for research focused on coastal evolution and environmental change. Marine geologic mapping of the inner continental shelf of Massachusetts is a statewide cooperative effort of the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management.

  6. Economic Disparities and Syphilis Incidence in Massachusetts, 2001-2013.

    We used area-level indicators of poverty to describe economic disparities in the incidence rate of infectious syphilis in Massachusetts to (1) determine whether methods developed in earlier AIDS analyses in Massachusetts could be applied to syphilis and (2) characterize syphilis trends during a time of increased rates of syphilis incidence. Using census tract data and population counts from the US Census Bureau and Massachusetts data on syphilis, we analyzed the incidence rate of syphilis infection from 2001 to 2013 by the poverty level of the census tract in which people with syphilis resided, stratified by age, sex, and race/ethnicity. The syphilis incidence rate increased in all census tract groups in Massachusetts from 2001 to 2013, and disparities in incidence rates by area poverty level persisted over time. The overall incidence rate of syphilis increased 6.9-fold from 2001 to 2013 in all census tract poverty-level groupings (from 1.5 to 10.3 per 100 000 population), but the rise in rate was especially high in the poorest census tracts (from 5.6 to 31.0 per 100 000 population) and among men (from 2.2 to 19.4 per 100 000 population). The highest syphilis incidence rate was among non-Hispanic black people. The largest changes in incidence rate occurred after 2010. One region had a disproportionate increase in incidence rates and a disproportionate impact on the statewide trend. Census tract poverty analyses can inform the targeting of interventions that make progress toward reducing disparities in rates of syphilis incidence possible.

    2007-01-01

    Introduction The U.S. Geological Survey (USGS) has mapped the sea floor of the Stellwagen Bank National Marine Sanctuary and western Massachusetts Bay, offshore of Boston, Massachusetts (figure 1a, figure 1b). The mapping was carried out using a Simrad Subsea EM1000 Multibeam Echo Sounder (95 kHz) on the Frederick G. Creed on four cruises between 1994 and 1998. The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick. This GIS Library contains images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys in an Environmental Systems Research Institute (http://www.esri.com) (ESRI) ArcMap 9.1 Geographic Information System (GIS) project. The shapefiles, images, grids and associated metadata may also be downloaded individually. Descriptions and interpretations of the data are available in a series of published maps.

    This report is divided into two parts. The first half describes on the history of thermoluminescence dating, and the latter half, the principle and measurement examples. It was in late 1955 that the measurement of radiation dose using thermoluminescence began. The method to thermoluminescence dating was developed when it was found that most natural stones emit the thermoluminescence. About Greek earthen wares, the study of which was presented in 1961 by G. Kennedy of University of California, the dating was able to be made within the standard deviation of 10%. Since then, this dating method progressed rapidly, and a number of laboratories are now forwarding the investigation. In the samples of natural materials, intensity of thermoluminescence I is proportional to natural radiation dose D which has been absorbed by the samples, i.e. I = kD, where k is the susceptibility of thermoluminescence of the samples. Since k is different in each sample, D can be determined by irradiating the sample with β or γ ray of known dose D 0 , measuring its luminescence I 0 , and eliminating k through these two equations, because i 0 = kD 0 . Next, if t is assumed to be the time passed since a pottery was made, D is expressed as Rt, where R is the natural radiation dose per year absorbed by the pottery. Thus t is determined if R is known. The report describes on the method of measuring R. As an example, the results of measurement of the potteries excavated at Iwakura remains, Yorikura, Taishaku-kyo, are listed. Results by 14 C dating are also described for reference. (Wakatsuki, Y.)

  12. Local and Cumulative Impervious Cover of Massachusetts Stream Basins

    2009-01-01

    Impervious surfaces such as paved roads, parking lots, and building roofs can affect the natural streamflow patterns and ecosystems of nearby streams. This dataset summarizes the percentage of impervious area for watersheds across Massachusetts by using a newly available statewide 1-m binary raster dataset of impervious surface for 2005. In order to accurately capture the wide spatial variability of impervious surface, it was necessary to delineate a new set of finely discretized basin boundaries for Massachusetts. This new set of basins was delineated at a scale finer than that of the existing 12-digit Hydrologic Unit Code basins (HUC-12s) of the national Watershed Boundary Dataset. The dataset consists of three GIS shapefiles. The Massachusetts nested subbasins and the hydrologic units data layers consist of topographically delineated boundaries and their associated percentage of impervious cover for all of Massachusetts except Cape Cod, the Islands, and the Plymouth-Carver region. The Massachusetts groundwater-contributing areas data layer consists of groundwater contributing-area boundaries for streams and coastal areas of Cape Cod and the Plymouth-Carver region. These boundaries were delineated by using groundwater-flow models previously published by the U.S. Geological Survey. Subbasin and hydrologic unit boundaries were delineated statewide with the exception of Cape Cod and the Plymouth-Carver Region. For the purpose of this study, a subbasin is defined as the entire drainage area upstream of an outlet point. Subbasins draining to multiple outlet points on the same stream are nested. That is, a large downstream subbasin polygon comprises all of the smaller upstream subbasin polygons. A hydrologic unit is the intervening drainage area between a given outlet point and the outlet point of the next upstream unit (Fig. 1). Hydrologic units divide subbasins into discrete, nonoverlapping areas. Each hydrologic unit corresponds to a subbasin delineated from the

    Murray-Wallace, C.V.

    1999-01-01

    The potential of the time-dependent amino acid racemisation reaction as a method of age assessment was first reported by Hare and Abelson (1968). They noted that in specimens of the bivalve mollusc Mercenaria sp., greater concentrations of amino acids in the D-configuration with increasing fossil age. Hare and Abelson (1968) also reported negligible racemisation in a modern specimen of Mecanaria sp. On this basis they suggested that the extent of amino acid racemisation (epimerisation in the case of isoleucine) may be used to assess the age of materials within and beyond the range of radiocarbon dating. For the past thirty years amino acid racemisation has been extensively applied in Quaternary research as a method of relative and numeric dating, and a particularly large literature has emerged on the subject

    2011-11-15

    Aim: To document the timing of the appearance of the radiological features of fracture healing in a group of infants in which the date of injury was known and to assess the degree of interobserver agreement. Materials and methods: Three paediatric radiologists independently assessed 161 images of 37 long bone fractures in 31 patients aged 0-44 months. The following features were assessed: soft-tissue swelling, subperiosteal new bone formation (SPNBF), definition of fracture line, presence or absence of callus, whether callus was well or ill defined, and the presence of endosteal callus. Results: Agreement between observers was only moderate for all discriminators except SPNBF. SPNBF was invariably seen after 11 days but was uncommon before this time even in the very young. In one case SPNBF was seen at 4 days. Conclusion: With the exception of SPNBF, the criteria relied on to date fractures are either not reproducible or are poor discriminators of fracture age.

Together we had a group of 6 faculty members and approximately 30 undergraduate students. Our house is ‘The EASI’ House, which stands for Efficient, Affordable, Solar Innovation. The EASI house is rectangular with two bedrooms and one bath, and offers a total square footage of 680. Based on competition estimates, The EASI house costs roughly $121,000. The EASI house has a 5kW solar system. Faculty and students from all three institutions were represented at the competition in Irvine California. Team MASSCA did well considering this was our first entry in the Solar Decathlon competition. Team MASSCA won the following awards: First Place – Affordability Contest Second Place – Energy Balance Contest. The competition provided a great experience for our students (and faculty as well). This competition provided leadership, endurance, and technical knowledge/skills for our students, and was the single most important hands-on experience during their undergraduate years. We are extremely pleased with the awards we received. At the same time we have learned from our efforts and would do better if we were to compete in the future. Furthermore, as a result of our team’s Inter-Americas collaborative effort, UTP and WNE have partnered to form Team PANAMASS (PANAma and MASSachusetts) and have developed The 3 SMART House for the inaugural Solar Decathlon Latin America & Caribbean competition held in Colombia.

    Despite prior focus on high-impact inpatient cases, there are increasing data and awareness that malpractice in the outpatient setting, particularly in primary care, is a leading contributor to malpractice risk and claims. To study patterns of primary care malpractice types, causes, and outcomes as part of a Massachusetts ambulatory malpractice risk and safety improvement project. Retrospective review of pooled closed claims data of 2 malpractice carriers covering most Massachusetts physicians during a 5-year period (January 1, 2005, through December 31, 2009). Data were harmonized between the 2 insurers using a standardized taxonomy. Primary care practices in Massachusetts. All malpractice claims that involved primary care practices insured by the 2 largest insurers in the state were screened. A total of 551 claims from primary care practices were identified for the analysis. Numbers and types of claims, including whether claims involved primary care physicians or practices; classification of alleged malpractice (eg, misdiagnosis or medication error); patient diagnosis; breakdown in care process; and claim outcome (dismissed, settled, verdict for plaintiff, or verdict for defendant). During a 5-year period there were 7224 malpractice claims of which 551 (7.7%) were from primary care practices. Allegations were related to diagnosis in 397 (72.1%), medications in 68 (12.3%), other medical treatment in 41 (7.4%), communication in 15 (2.7%), patient rights in 11 (2.0%), and patient safety or security in 8 (1.5%). Leading diagnoses were cancer (n = 190), heart diseases (n = 43), blood vessel diseases (n = 27), infections (n = 22), and stroke (n = 16). Primary care cases were significantly more likely to be settled (35.2% vs 20.5%) or result in a verdict for the plaintiff (1.6% vs 0.9%) compared with non-general medical malpractice claims (P < .001). In Massachusetts, most primary care claims filed are related to alleged misdiagnosis. Compared with malpractice

    Armstrong, David S.; Richards, Todd A.; Brandt, Sara L.

    2010-01-01

    The U.S. Geological Survey, in cooperation with the Massachusetts Department of Conservation and Recreation (MDCR), Massachusetts Department of Environmental Protection (MDEP), and the Massachusetts Department of Fish and Game (MDFG), conducted a preliminary investigation of fish communities in small- to medium-sized Massachusetts streams. The objective of this investigation was to determine relations between fish-community characteristics and anthropogenic alteration, including flow alteration and impervious cover, relative to the effect of physical basin and land-cover (environmental) characteristics. Fish data were obtained for 756 fish-sampling sites from the Massachusetts Division of Fisheries and Wildlife fish-community database. A review of the literature was used to select a set of fish metrics responsive to flow alteration. Fish metrics tested include two fish-community metrics (fluvial-fish relative abundance and fluvial-fish species richness), and five indicator species metrics (relative abundance of brook trout, blacknose dace, fallfish, white sucker, and redfin pickerel). Streamflows were simulated for each fish-sampling site using the Sustainable Yield Estimator application (SYE). Daily streamflows and the SYE water-use database were used to determine a set of indicators of flow alteration, including percent alteration of August median flow, water-use intensity, and withdrawal and return-flow fraction. The contributing areas to the fish-sampling sites were delineated and used with a Geographic Information System (GIS) to determine a set of environmental characteristics, including elevation, basin slope, percent sand and gravel, percent wetland, and percent open water, and a set of anthropogenic-alteration variables, including impervious cover and dam density. Two analytical techniques, quantile regression and generalized linear modeling, were applied to determine the association between fish-response variables and the selected environmental and

  13. Temporal patterns of migration and spawning of river herring in coastal Massachusetts

    Migrations of springtime Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis, collectively referred to as river herring, are monitored in many rivers along the Atlantic coast to estimate population sizes. While these estimates give an indication of annual differences in the number of returning adults, links to the subsequent timing and duration of spawning and freshwater juvenile productivity remain equivocal. In this study, we captured juvenile river herring at night in 20 coastal Massachusetts lakes using a purse seine and extracted otoliths to derive daily fish ages and back-calculate spawn dates. Estimates of spawning dates were compared with fishway counts of migrating adults to assess differences in migration timing and the timing and duration of spawning. We observed a distinct delay between the beginning of the adult migration run and the start of spawning, ranging from 7 to 28 d across the 20 lakes. Spawning continued 13–48 d after adults stopped migrating into freshwater, further demonstrating a pronounced delay in spawning following migration. Across the study sites the duration of spawning (43–76 d) was longer but not related to the duration of migration (29–66 d). The extended spawning period is consistent with recent studies suggesting that Alewives are indeterminate spawners. The long duration in freshwater provides the opportunity for top-down (i.e., predation on zooplankton) and bottom-up (i.e., food for avian, fish, and other predators) effects, with implications for freshwater food webs and nutrient cycling. General patterns of spawn timing and duration can be incorporated into population models and used to estimate temporal changes in productivity associated with variable timing and density of spawning river herring in lakes.

  14. Dating technique tested

    An analytical technique for dating ground water and polar ice up to a million years old has been successfully tested by scientists at Oak Ridge National Laboratory (ORNL). The system, known as a rare gas atom counter, extends the capabilities of resonance ionization mass spectrometry to include counting single atoms of krypton-81. The counter is composed of a pulsed dye laser operated in tandem with a mass spectrometer to separate the various isotopes of krypton. In a collaborative study, ORNL scientists recently used the method for the first time to count krypton-81 in a liter of ground water removed from a sandstone aquifer near Zurich. Fewer than 1000 krypton-81 atoms were isolated from the ground water samples. According to Bernard Lehman, a collaborating geochemist at the University of Bern, this first test proved that counting the small numbers of krypton-81 atoms necessary to make an estimate of the age of water could actually be done. Among the applications of this method, Lehman says, could be improved siting of locations for the disposal of radioactive wastes

    2005-01-01

    From its headwaters in Westborough, Massachusetts, to its confluence with the Sudbury River, the 53-kilometer-long Assabet River passes through a series of small towns and mixed land-use areas. Along the way, wastewater-treatment plants release nutrient-rich effluents that contribute to the eutrophic state of this waterway. This condition is most obvious where the river is impounded by a series of dams that have sequestered large amounts of sediment and support rooted and floating macrophytes and epiphytic algae. The water in parts of these impoundments may also have low concentrations of dissolved oxygen, another symptom of eutrophication. All of the impoundments had relatively shallow maximum water depths, which ranged from approximately 2.4 to 3.4 meters, and all had extensive shallow areas. Sediment volumes estimated for the six impoundments ranged from approximately 380 cubic meters in the Aluminum City impoundment to 580,000 cubic meters in the Ben Smith impoundment. The other impoundments had sediment volumes of 120,000 cubic meters (Powdermill), 67,000 cubic meters (Gleasondale), 55,000 cubic meters (Hudson), and 42,000 cubic meters (Allen Street). The principal objective of this study was the determination of sediment volume, extent, and chemistry, in particular, the characterization of toxic inorganic and organic chemicals in the sediments. To determine the bulk-sediment chemical-constituent concentrations, more than one hundred sediment cores were collected in pairs from the six impoundments. One core from each pair was sampled for inorganic constituents and the other for organic constituents. Most of the cores analyzed for inorganics were sectioned to provide information on the vertical distribution of analytes; a subset of the cores analyzed for organics was also sectioned. Approximately 200 samples were analyzed for inorganic constituents and 100 for organics; more than 10 percent were quality-control replicate or blank samples. Maximum bulk

  18. The effect of climate change on electricity expenditures in Massachusetts

    Climate change affects consumer expenditures by altering the consumption of and price for electricity. Previous analyses focus solely on the former, which implicitly assumes that climate-induced changes in consumption do not affect price. But this assumption is untenable because a shift in demand alters quantity and price at equilibrium. Here we present the first empirical estimates for the effect of climate change on electricity prices. Translated through the merit order dispatch of existing capacity for generating electricity, climate-induced changes in daily and monthly patterns of electricity consumption cause non-linear changes in electricity prices. A 2 °C increase in global mean temperature increases the prices for and consumption of electricity in Massachusetts USA, such that the average household’s annual expenditures on electricity increase by about 12%. Commercial customers incur a 9% increase. These increases are caused largely by higher prices for electricity, whose impacts on expenditures are 1.3 and 3.6 fold larger than changes in residential and commercial consumption, respectively. This suggests that previous empirical studies understate the effects of climate change on electricity expenditures and that policy may be needed to ensure that the market generates investments in peaking capacity to satisfy climate-driven changes in summer-time consumption. - Highlights: • Climate change increases summer peak of load curve in US state of Massachusetts. • Climate change increases electricity prices more than consumption. • Previous studies understate the effect of climate change on electricity expenditures. • Adaptation that reduces electricity demand may reduce the price effect. • Adaptation may raise prices by increasing capacity but lowering utilization rate.

    Geologic, sediment texture, and physiographic zone maps characterize the sea floor of Vineyard and western Nantucket Sounds, Massachusetts. These maps were derived from interpretations of seismic-reflection profiles, high-resolution bathymetry, acoustic-backscatter intensity, bottom photographs/video, and surficial sediment samples collected within the 494-square-kilometer study area. Interpretations of seismic stratigraphy and mapping of glacial and Holocene marine units provided a foundation on which the surficial maps were created. This mapping is a result of a collaborative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to characterize the surface and subsurface geologic framework offshore of Massachusetts.

  1. Radiocarbon Dating, Memories, and Hopes

    Science.gov (United States)

    Libby, W. F.

    1972-10-01

    The history of radiocarbon dating from 1939 to the present is reviewed. The basic principles of radiocarbon dating are that cosmic rays make living things radioactive with {sup 14}C to a certain level fixed by the environment and that at death the intake of food stops so no replenishment of the {sup 14}C steadily lost by the immutable decay occurs. Therefore measurement of the degree of decay gives the time lapse since death, i.e., the radiocarbon age. The equipment developed and experiments performed to measure the specific activity of specimens to be dated are described. The results obtained by world-wide experimenters are discussed. These showed that on simultaneity radiocarbon dating is apparently reliable but that absolute dates may be incorrect by as much as 600 to 700 y. The value of radiocarbon dating to archaeologists, geologists, climatologists, and historians is stressed. (LCL)

    International Nuclear Information System (INIS)

    Banerjee, D.

    1999-01-01

    Since the pioneering work by Huntley et al. (1985), optical dating is being increasingly recognised as an important technique for establishing a time frame of deposition of sediments (Aitken, 1998). Optical dating differs from thermoluminescence (TL) dating in that visible/infrared light from lasers or LEDs (light-emitting-diodes) is used as a means of stimulation, in contrast to thermal stimulation. It has several advantages over TL dating: (i) the resetting of the OSL (optically stimulated luminescence) clock is more effective than that of TL clock; for sediments transported under water or in other situations where the sediment grains have undergone inhomogeneous bleaching, this property ensures that ages based on optical dating are generally more reliable than TL ages, (ii) the optical dating technique is non-destructive, and multiple readouts of the optical signal is possible; this feature has resulted in the development of single-aliquot and single-grain protocols (Murray and Wintle, 1999; Banerjee et al. 1999), (iii) the sample is not heated as in TL; thus, spurious luminescence is avoided and there is a significant reduction in blackbody radiation. Dating of materials which change phase on heating is also practical, and finally, (iv) thermal quenching of luminescence is negligible, allowing accurate estimation of kinetic parameters using standard techniques and providing access to deep OSL traps.

    The Hartford-Deerfield basin, a Late Triassic to Early Jurassic rift basin located in central Connecticut and Massachusetts, is the northernmost basin of the onshore Mesozoic rift basins in the eastern United States. The presence of asphaltic petroleum in outcrops indicates that at least one active petroleum system has existed within the basin. However, to-date oil and gas wells have not been drilled in the basin to test any type of petroleum trap. There are good to excellent quality source rocks (up to 3.8% present day total organic carbon) within the Jurassic East Berlin and Portland formations. While these source rock intervals are fairly extensive and at peak oil to peak gas stages of maturity, individual source rock beds are relatively thin (typically less than 1 m) based solely on outcrop observations. Potential reservoir rocks within the Hartford-Deerfield basin are arkosic conglomerates, pebbly sandstones, and finer grained sandstones, shales, siltstones, and fractured igneous rocks of the Triassic New Haven and Jurassic East Berlin and Portland formations (and possibly other units). Sandstone porosity data from 75 samples range from less than 1% to 21%, with a mean of 5%. Permeability is equally low, except around joints, fractures, and faults. Seals are likely to be unfractured intra-formational shales and tight igneous bodies. Maturation, generation, and expulsion likely occurred during the late synrift period (Early Jurassic) accentuated by an increase in local geothermal gradient, igneous intrusions, and hydrothermal fluid circulation. Migration pathways were likely along syn- and postrift faults and fracture zones. Petroleum resources, if present, are probably unconventional (continuous) accumulations as conventionally accumulated petroleum is likely not present in significant volumes.

    Influenza peaks during the wintertime in temperate regions and during the annual rainy season in tropical regions - however reasons for the observed differences in disease ecology are poorly understood. We hypothesize that episodes of extreme precipitation also result in increased influenza in the Northeastern United States, but this association is not readily apparent, as no defined 'rainy season' occurs. Our objective was to evaluate the association between extreme precipitation (≥ 99th percentile) events and risk of emergency room (ER) visit for influenza in Massachusetts during 2002-2008. A case-crossover analysis of extreme precipitation events and influenza ER visits was conducted using hospital administrative data including patient town of residence, date of visit, age, sex, and associated diagnostic codes. Daily precipitation estimates were generated for each town based upon data from the National Oceanic and Atmospheric Administration. Odds ratio (OR) and 95% confidence intervals (CI) for associations between extreme precipitation and ER visits for influenza were estimated using conditional logistic regression. Extreme precipitation events were associated with an OR = 1.23 (95%CI: 1.16, 1.30) for ER visits for influenza at lag days 0-6. There was significant effect modification by race, with the strongest association observed among Blacks (OR = 1.48 (1.30, 1.68)). We observed a positive association between extreme precipitation events and ER visits for influenza, particularly among Blacks. Our results suggest that influenza is associated with extreme precipitation in a temperate area; this association could be a result of disease ecology, behavioral changes such as indoor crowding, or both. Extreme precipitation events are expected to increase in the Northeastern United States as climate change progresses. Additional research exploring the basis of this association can inform potential interventions for extreme weather events and influenza

    The absolute dating (radiocarbon, 14 C dating) and relative dating of Pringapus and Gondosuli temples in Temanggung regency (district) of Central Java Province have been carried out. The field sampling was done especially with the purpose to obtain vertical data, so that excavation method was adopted in the case. The main data were the ecofacts of organic habitation such as bones, woods, charcoals, shells, and paper artefacts. The artefacts data were used as a comparison. The comparative data analysis were conducted at Yogyakarta archaeological Department Laboratory, thus included dating of artefacts which were performed according to archaeological analysis procedures, generally based on the attributes attached to the artefacts, whereas the absolute dating of charcoal samples were performed in the Radiocarbon Dating Laboratory at Yogyakarta Nuclear Research Centre. Based on the relative dating of epigraphy content on the andesit rock from Gondosuli Temple which showed the year of 754 Saka or 832 AD, the Pringapus Temple was estimated to be built in the 850 AD. According to the absolute dating (Radiocarbon Dating with delta 13 C and tree ring corrections) the age for Gondosuli temple based on GDS/LU-2/Spit-7 samples is (384 -602) AD and from GDS/LU-2/Spit-8 = (452 - 652) AD. With these significant differences in the results obtained, it can be concluded that culture environment where the sample were collected already existed before the temple was built. Further investigation is still required

  12. Delineation of groundwater recharge areas, western Cape Cod, Massachusetts

    2000-01-01

    The unconfined sand-and-gravel aquifer in western Cape Cod, Massachusetts, which is the sole source of water supply for the communities in the area, is recharged primarily from precipitation. The rate of recharge from precipitation is estimated to be about 26 inches per year (in/yr), or about 60 percent of the precipitation rate. This recharge rate yields a flow through the aquifer of about 180 million gallons per day (Mgal/d). Groundwater flows radially outward from the top of the water-table mound in the north-central part of the flow system toward the coast, as indicated by the water-table contours on the large map on this sheet. Recharge that reaches the water table near the top of the mound travels deeper through the aquifer than recharge that reaches the water table closer to the coast. All recharge to the aquifer ultimately discharges to pumping wells, streams, or coastal areas; however, some of this recharge may flow first through kettle ponds before eventually reaching these discharge points.

    A supportive school-based physical activity environment (PAE) is integral to children's physical activity behaviors, but less understood is its association with academic achievement. We aimed to assess the association between PAE and academic performance and whether a stronger relationship exists in lower-income schools (LIS) compared to middle-income schools (MIS). Schoolchildren (grades 3rd to 5th) were recruited from 17 Massachusetts public schools. Schools were classified based on geographic characteristics and free/reduced-price lunch (FRPL) eligibility (LIS = 7, Median FRPL = 86%; MIS = 10, Median FRPL = 20%). PAE was measured using a 10-item survey. Mixed-effects logistic regression models were used to examine associations between PAE and scoring Advanced/Proficient on standardized Math and English Language Arts (ELA) tests. Demographic characteristics differed between LIS (N = 278, 5% non-Hispanic white) and MIS (N = 297, 73% non-Hispanic white). In LIS, PAE was associated with Math (odds ratio = 5.40, 95% CI = 2.52-11.54 p .05). There was no relationship between PAE and MIS test scores (p > .05). Schooltime moderate-to-vigorous physical activity was not associated with test scores (p > .05). A beneficial relationship exists between a high-PAE and test scores among LIS children, suggesting that the PAE may be associated with a more supportive environment and may be more fundamentally important for lower-income students. © 2017, American School Health Association.

    Child maltreatment is a serious public health concern, and its detrimental effects can be compounded by traumatic experiences associated with the child welfare (CW) system. Trauma-informed care (TIC) is a promising strategy for addressing traumatized children's needs, but research on the impact of TIC in CW is limited. This study examines initial findings of the Massachusetts Child Trauma Project, a statewide TIC initiative in the CW system and mental health network. After 1 year of implementation, Trauma-Informed Leadership Teams in CW offices emerged as key structures for TIC systems integration, and mental health providers' participation in evidence-based treatment (EBT) learning collaboratives was linked to improvements in trauma-informed individual and agency practices. After approximately 6 months of EBT treatment, children had fewer posttraumatic symptoms and behavior problems compared to baseline. Barriers to TIC that emerged included scarce resources for trauma-related work in the CW agency and few mental providers providing EBTs to young children. Future research might explore variations in TIC across service system components as well as the potential for differential effects across EBT models disseminated through TIC. © The Author(s) 2015.

    Children with special health care needs (CSHCN) face unique challenges in accessing affordable health care. Massachusetts implemented major health reform in 2006; little is known about the impact of this state's health reform on uninsurance, access to care, and financial protection for privately and publicly insured CSHCN. We used a difference-in-differences (DD) approach to compare uninsurance, access to primary and specialty care, and financial protection in Massachusetts versus other states and Washington, DC before and after Massachusetts health reform. Parent-reported data were used from the 2005-2006 and 2009-2010 National Survey of Children with Special Health Care Needs and adjusted for age, gender, race/ethnicity, non-English language at home, and functional difficulties. Postreform, living in Massachusetts was not associated with significant decreases in uninsurance or increases in access to primary care for CSHCN. For privately insured CSHCN, Massachusetts was associated with increased access to specialists (DD = 6.0%; P ≤ .001) postreform. For publicly insured CSHCN, however, there was a significant decrease in access to prescription medications (DD = -7.2%; P = .003) postreform. Living in Massachusetts postreform was not associated with significant changes in financial protection compared with privately or publicly insured CSHCN in other states. Massachusetts health reform likely improved access to specialists for privately insured CSHCN but did not decrease instances of uninsurance, increase access to primary care, or improve financial protection for CSHCN in general. Comparable provisions within the Affordable Care Act may produce similarly modest outcomes for CSHCN. Copyright © 2014 by the American Academy of Pediatrics.

  18. Dating the humans by radiocarbon

    2011-01-01

    Radiocarbon has become a very powerful tool used for dating. This paper deals with a specific application of 1 4C i.e. dating of humans. Attention is focused on those aspects that, if neglected, might lead to a misinterpretation of the results or to an unsatisfying accuracy of the measurement. After a brief description of the main principles on which the radiocarbon method is based and of Accelerator Mass Spectrometry, examples taken from the research activity of INFN-LABEC (Laboratorio di Tecniche Nucleari per I Beni Culturali) in Florence are presented. The case of the relic of St. Francis represents an example of dating not directly human remains but other objects that can be associated to them. The case of two burials from the archaeological area of Baratti-Populonia, in Tuscany, gives the possibility to show the importance of estimating the human palaeodiet when dating bone samples.

  19. Linguistic Dating of Biblical Texts

    For two centuries, scholars have pointed to consistent differences in the Hebrew of certain biblical texts and interpreted these differences as reflecting the date of composition of the texts. Until the 1980s, this was quite uncontroversial as the linguistic findings largely confirmed...... the chronology of the texts established by other means: the Hebrew of Genesis-2 Kings was judged to be early and that of Esther, Daniel, Ezra, Nehemiah, and Chronicles to be late. In the current debate where revisionists have questioned the traditional dating, linguistic arguments in the dating of texts have...... come more into focus. The study critically examines some linguistic arguments adduced to support the traditional position, and reviewing the arguments it points to weaknesses in the linguistic dating of EBH texts to pre-exilic times.

    Full Text Available To evaluate date stones as dietary component for broilers, two trials were carried out. In the first trial, Tunisian Deglet date stones were used and in the second one, stones were the waste product of an Italian distillery. One-day-old Arbor Acres chickens were cage reared and fed for 6 weeks on 4 experimental diets, which were formulated to be isonitrogenous and isocaloric and differed in cereal component (maize or low tannin sorghum and in inclusion level (0 or 10 % of ground date stones. Birds ' performances were slightly different in the two trials, but overall results indicate that date stones are suitable for use in broiler's feeding under such conditions.

    2006-01-01

    The methods that can be used for the direct dating of human remains comprise of radiocarbon, U-series, electron spin resonance (ESR), and amino acid racemization (AAR). This review gives an introduction to these methods in the context of dating human bones and teeth. Recent advances in ultrafiltration techniques have expanded the dating range of radiocarbon. It now seems feasible to reliably date bones up to 55,000 years. New developments in laser ablation mass spectrometry permit the in situ analysis of U-series isotopes, thus providing a rapid and virtually non-destructive dating method back to about 300,000 years. This is of particular importance when used in conjunction with non-destructive ESR analysis. New approaches in AAR analysis may lead to a renaissance of this method. The potential and present limitations of these direct dating techniques are discussed for sites relevant to the reconstruction of modern human evolution, including Florisbad, Border Cave, Tabun, Skhul, Qafzeh, Vindija, Banyoles, and Lake Mungo.

  7. Radiocarbon dating of iron artefacts

    1997-12-31

    Iron artefacts are generally dated by association or on stylistic grounds. This may not give a true indication of the date of manufacture, or may not be possible if the piece is out of context, ambiguous in style, or a copy. Obtaining a direct date on the artefact would be preferable. During the processes of manufacture, carbon is incorporated into the iron from the fuel source. If the fuel is of a material containing contemporaneous carbon, i.e. has an ambient radiocarbon signature, e.g. charcoal, then we may reliably radiocarbon date the artefact by extracting this carbon. Care must be taken, however, to ensure that re-working has not introduced multiple sources of carbon that would give an erroneous date. Detailed chemical analysis must precede radiocarbon analysis. Sample size is determined by carbon content, and before the advent of accelerator mass spectrometry, several tens of grams of carbon were required for radiocarbon dating (van der Merwe, 1969), prohibiting this method except for high-carbon cast-irons and bulk samples, e.g. caches of nails. AMS permits the analysis of sub-gram pieces of iron (Cresswell, 1991), thereby permitting the analysis of museum pieces with only minimal loss of material, and small fragments of iron recovered from archaeological sites. A few examples are given to illustrate these points. Paper no. 41; Extended abstract. 6 refs.

  10. Walden Pond, Massachusetts: Environmental Setting and Current Investigations

    Colman, John A.; Waldron, Marcus C.

    1998-01-01

    Introduction Walden Pond, in Concord, Massachusetts, is famous among lakes because of its unique social history. Walden was the setting for American naturalist Henry David Thoreau's well-known essay 'Walden; or, Life in the Woods,' first published in 1854. Thoreau lived and wrote at Walden Pond from July 1845 to September 1847. In 'Walden,' Thoreau combined highly admired writing on Transcendental philosophy with pioneering observations of aquatic ecology and physical aspects of limnology, the study of lakes. Because Thoreau also defended so effectively the value of living close to nature in the Walden woods, the pond is considered by many to be the birthplace of the American conservation movement. Visitors come from all over the world to the pond, which has been designated a National Historic Landmark, and its fame has resulted in a major fund drive to preserve the surrounding woods. Walden Pond has no surfacewater inflow or outflow, and much of its ground-water contributing area likely is preserved within the Walden Pond Reservation area (fig. 1). Only 15 miles from Boston, the pond is unusually clear and pristine for an urban-area lake. However, point sources of nutrients near the pond, and a large annual visitor attendance, concentrated during the summer when the swimming beach (fig. 2) is open, may contribute a nutrient load sufficient to change the pond environment. The occurrence of nuisance algal species, a recent beach closing, and an awareness of water-quality problems suffered by other ponds in the region raise concerns about the risk of ecological change at Walden Pond. Despite the role of Walden Pond as a cultural and environmental icon, little is known about the pond's ecological features, such as its internal nutrient cycling or the structure of its food web, nor have consistent measurements been made to determine whether these features are changing or are stable. Production rates of aquatic plants in lakes and ponds naturally undergo a slow increase

    Background The 2006 Massachusetts health reform substantially decreased uninsurance rates. Yet, little is known about the reform’s impact on actual healthcare utilization among poor and minority populations, particularly for receipt of inpatient surgical procedures that are commonly initiated by outpatient physician referral. Methods Using discharge data on MA hospitalizations for 21 months preceding and following health reform implementation (7/1/2006 – 12/31/2007), we identified all non-obstetrical major therapeutic procedures for patients aged ≥ 40 and for which ≥70 percent of hospitalizations were initiated by outpatient physician referral. Stratifying by race/ethnicity and patient residential zip code median (area) income, we estimated pre- and post-reform procedure rates, and their changes, for those aged 40–64 (non-elderly), adjusting for secular changes unrelated to reform by comparing to corresponding procedure rate changes for those aged >= 70 (elderly), whose coverage (Medicare) was not affected by reform. Results Overall increases in procedure rates (among 17 procedures identified) between pre- and post-reform periods were higher for non-elderly low area income (8%, p=0.04) and medium area income (8%, preform, post-reform increases in procedure utilization among non-elderly were: by area income, low=13% (95% CI=[9%, 17%]), medium=15% ([6%, 24%]) and high=2% ([−3%, 8%]), and by race/ethnicity, Hispanics=22% ([5%, 38%]), Blacks=5% ([−20%, 30%]) and Whites=7% ([5%, 10%]). Conclusions Post-reform use of major inpatient procedures increased more among non-elderly lower and medium area income populations, Hispanics, and whites, suggesting potential improvements in access to outpatient care for these vulnerable subpopulations.

    Fourteen years of newborn screening in Massachusetts for congenital toxoplasmosis infection identified subpopulations that appeared to have higher rates of infection. Elaborating an epidemiologic profile and risk correlates might aid implementing targeted prenatal education and newborn screening strategies with the goal of early postnatal treatment to prevent morbidity. To describe the epidemiology of congenital toxoplasmosis in Massachusetts and risk correlates of infection using birth certificate data. A case-control study was conducted based on Massachusetts birth certificate data. Cases were all infants with congenital toxoplasmosis identified by statewide universal newborn screening from 1988 to 1999. Controls were all children born on the same day as those infants in Massachusetts. Factors that strongly predicted congenital toxoplasmosis infection were mother's country of birth outside the US (especially the southeast Asian refugee origin countries of Cambodia and Laos), mother's educational level and higher gravidity. More extensive, culturally and linguistically appropriate, prenatal education is needed for pregnant women, regardless of a mother's educational level, especially for non-US-born mothers, and not focused only on primiparous women. Other states may be able to use their state-specific birth certificate data to compare risk profiles with those of Massachusetts to guide a toxoplasmosis screening policy on the basis of population similarities and differences.

    An environmental and economic evaluation of the smoke-free law in Massachusetts provides a broad appreciation of how a state-wide smoking ban affects the health of patrons and workers as well as the industries that are commonly concerned about the effects of smoking bans on business. The aim of this study is to evaluate environmental and economic effects of the statewide Massachusetts statewide Smoke-Free Workplace Law. Before and after the smoking ban, air quality testing was conducted in a sample (n = 27) of hospitality venues and state-wide economic changes were assessed. Compliance, in terms of patronage was measured by person-counts. Environmental outcomes were respirable suspended particles (RSP) less than 2.5 microns in diameter (PM2.5). Economic outcomes were meals tax collections, employment in the food services and drinking places and accommodations industries. On average, levels of respirable suspended particles (RSPs) less than 2.5 microns in diameter (PM2.5) decreased 93% in these venues after the Massachusetts Smoke-free Workplace Law went into effect. No statistically significant changes were observed among the economic indicators. This evaluation demonstrates that the state-wide Massachusetts law has effectively improved indoor air quality in a sample of Massachusetts venues and has not negatively affected several economic indicators.

    Access to behavioral health care for children is essential to achieving good health care outcomes. Pediatric primary care providers have an essential role to play in identifying and treating behavioral health problems in children. However, they lack adequate training and resources and thus have generally been unable to meet children's need for behavioral health care. The Massachusetts Child Psychiatry Access Project has addressed this problem by delivering telephone child psychiatry consultations and specialized care coordination support to over 95 percent of the pediatric primary care providers in Massachusetts. Established in 2004, the project consists of six regional hubs, each of which has one full-time-equivalent child psychiatrist, licensed therapist, and care coordinator. Collectively, the hubs are available to over 95 percent of the 1.5 million children in Massachusetts. In fiscal year 2013 the Massachusetts Child Psychiatry Access Project served 10,553 children. Pediatric primary care providers enrolled in the project reported a dramatic improvement in their ability to meet the psychiatric needs of their patients. Telephone child psychiatry consultation programs for pediatric primary care providers, many modeled after the Massachusetts project, have spread across the United States.

    States frequently expand or limit dental benefits for adults covered by Medicaid. As part of statewide health reform in 2006, Massachusetts expanded dental benefits to all adults ages 19-64 whose annual income was at or below 100 percent of the federal poverty level. We examined the impact of this reform and found that it led to an increase in dental care use among the Massachusetts adult population, driven by gains among poor adults. Compared to the prereform period, dental care use increased by 2.9 percentage points among all nonelderly adults in Massachusetts, relative to all nonelderly adults in eight control states. For poor Massachusetts adults, the effect was larger-an eleven-percentage-point increase in dental care use above the increase among the state's nonpoor residents. The Massachusetts experience provides evidence that providing dental benefits to poor adults through Medicaid can improve dental care access and use. Our results imply that the lack of expanded dental coverage for low-income adults under the Affordable Care Act is a missed opportunity to improve access to oral care.

    The U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM) have mapped approximately 340 square kilometers of the inner continental shelf in Vineyard Sound, Massachusetts, under a cooperative mapping program. The geophysical data collected between 2009 and 2011 by the U.S. Geological Survey as part of this program are published in this report. The data include (1) swath bathymetry from interferometric sonar, (2) acoustic backscatter from sidescan sonar, and (3) seismic-reflection profiles from a chirp subbottom profiler. These data were collected to support research on the influence of sea-level change and sediment supply on coastal evolution and sediment transport processes and to provide baseline seabed characterization information required for management of coastal and offshore resources within the coastal zone of Massachusetts.

    The authors examined trends and predictors of public support for smoke-free restaurants in Massachusetts. Since 1992, the Massachusetts Behavioral Risk Factor Surveillance System has asked survey respondents about their attitudes toward smoking in restaurants. Analyses using data from 1992 to 1999 characterized changes over time in support for smoke-free restaurants and the role of demographic and smoking-related factors in predicting support. During 1992 to 1999, the rate of support for smoke-free restaurants increased from 37.5% to 59.8%, with similar increases among current, former, and never smokers. After adjustment for smoking status, support was associated with socioeconomic characteristics, race/ethnicity, and household smoking rules. Among current smokers, lighter smokers and those who were trying to quit were more likely to endorse smoke-free restaurants. There has been a substantial increase in support for smoke-free restaurants among both smokers and nonsmokers in Massachusetts.

  2. What Health Care Reform Means for Immigrants: Comparing the Affordable Care Act and Massachusetts Health Reforms.

    2016-02-01

    The 2010 Patient Protection and Affordable Care Act (ACA) was passed to provide more affordable health coverage to Americans beginning in 2014. Modeled after the 2006 Massachusetts health care reform, the ACA includes an individual mandate, Medicaid expansion, and health exchanges through which middle-income individuals can purchase coverage from private insurance companies. However, while the ACA provisions exclude all undocumented and some documented immigrants, Massachusetts uses state and hospital funds to extend coverage to these groups. This article examines the ACA reform using the Massachusetts reform as a comparative case study to outline how citizenship status influences individuals' coverage options under both policies. The article then briefly discusses other states that provide coverage to ACA-ineligible immigrants and the implications of uneven ACA implementation for immigrants and citizens nationwide.

    2009-01-01

    For the waiting world, and indeed for most of us here at CERN, ‘the LHC schedule’ simply means the date that the LHC will restart - and we only take notice when that end-date changes. But in fact the schedule is a constantly evolving intricate document coordinating all the repairs, consolidation and commissioning in every part of the machine. So, what actually goes on behind the scenes in timing and planning all the work on one of the most complex scientific instruments ever built?

  6. Medicaid coverage for tobacco dependence treatments in Massachusetts and associated decreases in smoking prevalence.

    Directory of Open Access Journals (Sweden)

    Thomas Land

    2010-03-01

    Full Text Available Approximately 50% of smokers die prematurely from tobacco-related diseases. In July 2006, the Massachusetts health care reform law mandated tobacco cessation coverage for the Massachusetts Medicaid population. The new benefit included behavioral counseling and all medications approved for tobacco cessation treatment by the U.S. Food and Drug Administration (FDA. Between July 1, 2006 and December 31, 2008, a total of 70,140 unique Massachusetts Medicaid subscribers used the newly available benefit, which is approximately 37% of all Massachusetts Medicaid smokers. Given the high utilization rate, the objective of this study is to determine if smoking prevalence decreased significantly after the initiation of tobacco cessation coverage.Smoking prevalence was evaluated pre- to post-benefit using 1999 through 2008 data from the Massachusetts Behavioral Risk Factor Survey (BRFSS. The crude smoking rate decreased from 38.3% (95% C.I. 33.6%-42.9% in the pre-benefit period compared to 28.3% (95% C.I.: 24.0%-32.7% in the post-benefit period, representing a decline of 26 percent. A demographically adjusted smoking rate showed a similar decrease in the post-benefit period. Trend analyses reflected prevalence decreases that accrued over time. Specifically, a joinpoint analysis of smoking prevalence among Massachusetts Medicaid benefit-eligible members (age 18-64 from 1999 through 2008 found a decreasing trend that was coincident with the implementation of the benefit. Finally, a logistic regression that controlled for demographic factors also showed that the trend in smoking decreased significantly from July 1, 2006 to December 31, 2008.These findings suggest that a tobacco cessation benefit that includes coverage for medications and behavioral treatments, has few barriers to access, and involves broad promotion can significantly reduce smoking prevalence.

  7. Expanding coverage to low-income childless adults in Massachusetts: implications for national health reform.

    2014-12-01

    To draw on the experiences under Massachusetts's 2006 reform, the template for the Affordable Care Act (ACA), to provide insights into the potential impacts of the ACA Medicaid expansion for low-income childless adults in other states. The study takes advantage of the natural experiment in Massachusetts and combined data from two surveys-the Massachusetts Health Reform Survey (MHRS) and the National Health Interview Survey (NHIS)-to estimate the impacts of reform on low-income adults. Difference-in-differences models of the impacts of health reform, using propensity-score reweighting to improve the match between Massachusetts and the comparison states. Data for low-income adults are obtained by combining data from the MHRS and the NHIS, where the MHRS provides a relatively large Massachusetts sample and the NHIS provides data for samples in other states to support the difference-in-differences model. Supplemental data on county economic and health care market characteristics are obtained from the Area Health Resource File. There are strong increases in coverage and access to health care for low-income adults under health reform in Massachusetts, with the greatest gains observed for childless adults, who were not eligible for public coverage prior to reform. In the states that implement the Medicaid provisions of the ACA, we would expect to see large increases in coverage rates and commensurate gains in access to care for low-income childless adults. Linking state and federal surveys offers a strategy for leveraging the value of state-specific survey data for stronger policy evaluations. © Health Research and Educational Trust.

    Full Text Available This paper uses a sociological stress process model to explore the Khmer adult refugees' experience in Massachusetts. The analysis is based on the responses of three focus groups in the Khmer communities of Lowell, Lynn, and Revere, Massachusetts. The focus groups provided an in-depth understanding of sources of stress, stress mediators, and psychosocial adjustment/adaptational patterns for Khmer refugees who had experienced the Cambodian genocide. Symptoms and reactions associated with underlying causes of mental health problems had culturally specific relevance to physical illness and mental health.

    2005-01-01

    Since their inception in 1965, community health centers have thrived against tough odds, including patchwork funding, an unpredictable public policy environment, and a volatile healthcare marketplace. Much of this long-term success has been attributed to the centers' ability to affect their economic and political environment. Massachusetts provides an excellent example of this outward orientation. It was here that the centers first took hold, grew rapidly as a result of grassroots activity, and came together as a group for advocacy and mutual assistance. This article examines the Massachusetts experience in light of the health centers' ability to survive and grow.

    The geologic framework of the Massachusetts inner continental shelf between Cape Ann and Salisbury Beach has been shaped by a complicated history of glaciation, deglaciation, and changes in relative sea level. New geophysical data (swath bathymetry, sidescan sonar and seismic-reflection profiling), sediment samples, and seafloor photography provide insight into the geomorphic and stratigraphic record generated by these processes. High-resolution spatial data and geologic maps in this report support coastal research and efforts to understand the type, distribution, and quality of subtidal marine habitats in the Massachusetts coastal ocean.

    High-dose ionizing radiation is associated with circulatory disease. Risks from lower-dose fractionated exposures, such as from diagnostic radiation procedures, remain unclear. In this study we aimed to ascertain the relationship between fractionated low-to-medium dose radiation exposure and circulatory disease mortality in a cohort of 13,568 tuberculosis patients in Massachusetts, some with fluoroscopy screenings, between 1916 and 1961 and follow-up until the end of 2002. Analysis of mortality was in relation to cumulative thyroid (cerebrovascular) or lung (all other circulatory disease) radiation dose via Poisson regression. Over the full dose range, there was no overall radiation-related excess risk of death from circulatory disease (n = 3221; excess relative risk/Gy −0.023; 95 % CI −0.067, 0.028; p = 0.3574). Risk was somewhat elevated in hypertensive heart disease (n = 89; excess relative risk/Gy 0.357; 95 % CI −0.043, 1.030, p = 0.0907) and slightly decreased in ischemic heart disease (n = 1950; excess relative risk/Gy −0.077; 95 % CI −0.130, −0.012; p = 0.0211). However, under 0.5 Gy, there was a borderline significant increasing trend for all circulatory disease (excess relative risk/Gy 0.345; 95 % CI −0.032, 0.764; p = 0.0743) and for ischemic heart disease (excess relative risk/Gy 0.465; 95 % CI, −0.032, 1.034, p = 0.0682). Pneumolobectomy increased radiation–associated risk (excess relative risk/Gy 0.252; 95 % CI 0.024, 0.579). Fractionation of dose did not modify excess risk. In summary, we found no evidence of radiation-associated excess circulatory death risk overall, but there are indications of excess circulatory death risk at lower doses (<0.5 Gy). Although consistent with other radiation-exposed groups, the indications of higher risk at lower doses are unusual and should be confirmed against other data.

    Childhood obesity is a multifaceted disease that requires sustainable, multidimensional approaches that support change at the individual, community, and systems levels. The Massachusetts Childhood Obesity Research Demonstration project addressed this need by using clinical and public health evidence-based methods to prevent childhood obesity. To date, little information is known about successes and lessons learned from implementing such large-scale interventions. To address this gap, we examined perspectives of community stakeholders from various sectors on successes achieved and lessons learned during the implementation process. We conducted 39 semistructured interviews with key stakeholders from 6 community sectors in 2 low-income communities from November 2013 through April 2014, during project implementation. Interviews were audio-recorded, transcribed, and analyzed by using the constant comparative method. Data were analyzed by using QSR NVivo 10. Successes included increased parental involvement in children's health and education, increased connections within participating organizations and within the broader community, changes in organizational policies and environments to better support healthy living, and improvements in health behaviors in children, parents, and stakeholders. Lessons learned included the importance of obtaining administrative and leadership support, involving key stakeholders early in the program planning process, creating buffers that allow for unexpected changes, and establishing opportunities for regular communication within and across sectors. Study findings indicate that multidisciplinary approaches support health behavior change and provide insight into key issues to consider in developing and implementing such approaches in low-income communities.

  4. Adolescent Bullying, Dating, and Mating

    Directory of Open Access Journals (Sweden)

    Anthony A. Volk

    2015-11-01

    Full Text Available Traditionally believed to be the result of maladaptive development, bullying perpetration is increasingly being viewed as a potentially adaptive behavior. We were interested in determining whether adolescents who bully others enjoy a key evolutionary benefit: increased dating and mating (sexual opportunities. This hypothesis was tested in two independent samples consisting of 334 adolescents and 144 university students. The data partly supported our prediction that bullying, but not victimization, would predict dating behavior. The data for sexual behavior more clearly supported our hypothesis that bullying behavior predicts an increase in sexual opportunities even when accounting for age, sex, and self-reports of attractiveness, likeability, and peer victimization. These results are generally congruent with the hypothesis that bullying perpetration is, at least in part, an evolutionary adaptive behavior.

  5. Neutrino, radioactivity and dating wines

    International Nuclear Information System (INIS)

    Hubert, Ph.

    2004-01-01

    Wine is a witness of the radioactivity of the atmosphere at the moment of grapes were collected. The possibility of measuring very low radioactivity levels (that was developed for studying neutrinos) has permitted the design of a new non-destructive method of dating bottled wines. This method is based on the detection of the 661 keV photon released whenever an atom of cesium 137 decays. This photon has enough energy to cross the thickness of glass and be detected. The presence of cesium 137 in the atmosphere is mainly due to the military atomic tests performed from 1950 to 1963 and to the Chernobyl accident that took place in 1986, as a consequence this method is valid to date wines that were produced only after 1950.

We carried out ESR dating of fault rocks collected near the Gori nuclear reactor. Most of the ESR signals of fault rocks collected from the basement are saturated. This indicates that the last movement of the faults had occurred before the Quaternary period. However, ESR dates from the Oyong fault zone range from 370 to 310 ka. Results of this research suggest that long-term cyclic fault activity of the Oyong fault zone continued into the Pleistocene

  7. Current topics in ESR dating

    International Nuclear Information System (INIS)

    Skinner, Anne R.

    2011-01-01

    After over 25 years, the use of electron spin resonance (ESR) is well-established in dating sites of geological, paleontological and archaeological interest. Like any scientific technique, there have been changes in understanding and in methodology. Improvements have not, however, changed the observation that external dose calculations are still a significant source of uncertainty in ages. Examples from Europe, Africa and the Americans illustrate this point. For Pradayrol Cave (France), the occupation age, 330 ka, is unchallenged, making this the oldest known Neanderthal site in France. For Roc de Marsal, also in France, on the other hand, discrepancies between TL and sedimentary dose rates imply substantial differences in interpretation. In the Western Egyptian Desert, where artifacts and datable material are not well-correlated, the dating results show consistency with expectations based on global climate change, even in deflated sites. Climate change is also the question in geological studies in the Bahamas where, despite concerns about cosmic dose history, ESR dates confirm other evidence for sea level changes. We show that an uncertain age is not the same as an impossible one.

    2017-12-01

    The prescription opioid crisis has involved all sectors of U.S. society, affecting every community, socioeconomic group, and age group. While federal and state agencies are actively working to deal with the epidemic, medical and dental providers have been tasked to increase their awareness of the issues and consider ways to safely prescribe opioids and, at the same time, effectively treat their patients' pain. The Commonwealth of Massachusetts, under the leadership of Governor Charles D. Baker and his administration, challenged the state's four medical schools and three dental schools to improve their curricula to prepare the next generation of clinicians to deal with this crisis in an evidence-based, effective, and sympathetic way. This Perspectives article outlines the national prescription opioid crisis, details its effects in Massachusetts, and describes the interdisciplinary collaboration among the Commonwealth, the three dental schools, the Massachusetts Dental Society, and a concerned student group. The article also describes the efforts each dental school is undertaking as well as an assessment of the challenges and limitations in implementing the initiative. The authors hope that the Massachusetts model will be a useful resource for dental schools in other states.

  4. Surficial and applied surficial geology of the Belchertown Quadrangle, Massachusetts

    Science.gov (United States)

    Caggiano, Joseph A.

    1977-01-01

    Till and stratified drift overlie maturely dissected topography in the Belchertown quadrangle, an area that straddles the New England Upland and Connecticut Valley Lowland in central Massachusetts. Lower Paleozoic, massive quartzo-feldspathic gneiss, quartzite and schist of the Pelham dome and Devonian granodiorite and quartz diorite of the Belchertown intrusive complex are in contact with Triassic arkosic fanglomerate and basalt along a lengthy normal fault separating the New England Upland from the Connecticut Valley Lowland. The orientation of striae, roches moutonnees, and streamline ridges indicate that the last Wisconsinian glacier advanced generally south 12? east. This glacier removed several meters of rock from the upland and an unknown larger quantity from the preglacial valley of the Connecticut River. Till is thin in the uplands, but several tens of feet of drift overlie bedrock in the lowland. Three lithic facies of sandy, clast-rich, non-compact, subarkosic till derived from the three major source rocks rest on bedrock or on highly weathered, compact, clast-poor, fissile probably older till. The mean for all upper till is 69.6% sand, 21.7% silt, and 8.8% clay; lower till consists of 48% sand, 23% silt and 29% clay. Mud-rich, compact, sparsely stony till in drumlins in and along the flank of the Connecticut Valley Lowland is composed of 51.5% sand, 28% silt, and 20.5% clay. Upper tills are facies equivalent deposits of the youngest Wisconsinian drift. Lower till is compact deeply weathered, jointed and stained suggesting it is correlative with other lower till in New England deposited by an earlier Wisconsinian glacier. Drumlin till may be a facies equivalent of a lower till or a mud-rich upper till derived from earlier glaciolacustrine deposits. Upper and lower till of the Belchertown quadrangle is texturally similar to other New England upper and lower tills to which they are equivalent. Both tills are interpreted as lodgment till derived from

    To assess the validity of outcome data reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) compared with data from vital records and the birth defects registry in Massachusetts. Longitudinal cohort. Not applicable. A total of 342,035 live births and fetal deaths from Massachusetts mothers giving birth in the state from July 1, 2004, to December 31, 2008; 9,092 births and fetal deaths were from mothers who had conceived with the use of assisted reproductive technology (ART) and whose cycle data had been reported to the SART CORS. Not applicable. Percentage agreement between maternal race and ethnicity, delivery outcome (live birth or fetal death), plurality (singleton, twin, or triplet+), delivery date, and singleton birth weight reported in the SART CORS versus vital records; sensitivity and specificity for birth defects among singletons as reported in the SART CORS versus the Massachusetts Birth Defects Monitoring Program (BDMP). There was >95% agreement between the SART CORS and vital records for fields of maternal race/ethnicity, live birth/fetal death, and plurality; birth outcome date was within 1 day with 94.9% agreement and birth weight was within 100 g with 89.6% agreement. In contrast, sensitivity for report of any birth defect was 38.6%, with a range of 18.4%-50.0%, for specific birth defect categories. Although most SART CORS outcome fields are accurately reported, birth defect variables showed poor sensitivity compared with the gold standard data from the BDMP. We suggest that reporting of birth defects be discontinued. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  6. Reactive-transport simulation of phosphorus in the sewage plume at the Massachusetts Military Reservation, Cape Cod, Massachusetts

    Science.gov (United States)

    Parkhurst, David L.; Stollenwerk, Kenneth G.; Colman, John A.

    2003-01-01

    The subsurface transport of phosphorus introduced by the disposal of treated sewage effluent to ground-infiltration disposal beds at the Massachusetts Military Reservation on western Cape Cod was simulated with a three-dimensional reactive-transport model. The simulations were used to estimate the load of phosphorus transported to Ashumet Pond during operation of the sewage-treatment plant?from 1936 to 1995?and for 60 years following cessation of sewage disposal. The model accounted for spatial and temporal changes in water discharge from the sewage-treatment plant, ground-water flow, transport of associated chemical constituents, and a set of chemical reactions, including phosphorus sorption on aquifer materials, dissolution and precipitation of iron- and manganese-oxyhydroxide and iron phosphate minerals, organic carbon sorption and decomposition, cation sorption, and irreversible denitrification. The flow and transport in the aquifer were simulated by using parameters consistent with those used in previous flow models of this area of Cape Cod, except that numerical dispersion was much larger than the physical dispersion estimated in previous studies. Sorption parameters were fit to data derived from phosphorus sorption and desorption laboratory column experiments. Rates of organic carbon decomposition were adjusted to match the location of iron concentrations in an anoxic iron zone within the sewage plume. The sensitivity of the simulated load of phosphorus transported to Ashumet Pond was calculated for a variety of processes and input parameters. Model limitations included large uncertainties associated with the loading of the sewage beds, the flow system, and the chemistry and sorption characteristics in the aquifer. The results of current model simulations indicate a small load of phosphorus transported to Ashumet Pond during 1965?85, but this small load was particularly sensitive to model parameters that specify flow conditions and the chemical process by

  7. Predicting Teen Dating Violence Perpetration.

    Science.gov (United States)

    Cohen, Joseph R; Shorey, Ryan C; Menon, Suvarna V; Temple, Jeff R

    2018-04-01

    With our study we aimed to (1) understand what factors uniquely conferred risk for physical and sexual forms of teen dating violence (TDV) perpetration and (2) create a screening algorithm to quantify perpetration risk on the basis of these factors. A total of 1031 diverse public high school students living in Southeast Texas participated in our study (56% female; 29% African American, 28% white, and 31% Hispanic). Self-report measures concerning TDV and associated risk factors were completed annually for 6 years. Results suggested that family violence (domestic violence exposure, maltreatment) together with deficits in conflict resolution incrementally improved our forecasts above and beyond lifetime history of physical TDV perpetration (net reclassification improvement = 0.44; 95% confidence interval [CI] = 0.30-0.59). Meanwhile, a violent dating history (TDV sexual perpetration, sexual victimization, and emotional perpetration) and acceptance of TDV incrementally improved our models for forecasting sexual forms of perpetration (net reclassification improvement = 0.41; 95% CI = 0.24-0.58). These models adequately discriminated between future perpetrators and nonoffenders (area under the curve statistic >0.70; 95% CI: 0.69-0.74). Overall, adolescents with positive test results on our algorithms were over twice as likely to perpetrate dating violence over the course of 6 years. Our study represents one of the first applications of reclassification analyses to psychosocial research in a pediatric population. The result is a theoretically informed, empirically based algorithm that can adequately estimate the likelihood of physical and sexual TDV perpetration during vulnerable developmental periods. These findings can immediately aid emerging preventive initiatives for this increasing public health concern. Copyright © 2018 by the American Academy of Pediatrics.

    The extent to which an accurate determination of the age of the Galaxy, and thus a lower bound on the age of the universe, can be obtained from radioactive dating is discussed. Emphasis is given to the use of the long-lived radioactive nuclei Re-187, Th-232, U-238, and U-235. The nature of the production sites of these and other potential Galactic chronometers is examined along with their production ratios. Age determinations from models of nucleocosmochronology are reviewed and compared with age determination from stellar sources and age constraints form cosmological considerations.

    Long, Sharon K; Stockley, Karen

    2011-01-01

    Objective To analyze the effects of health reform efforts in two large states—New York and Massachusetts. Data Sources/Study Setting National Health Interview Survey (NHIS) data from 1999 to 2008. Study Design We take advantage of the “natural experiments” that occurred in New York and Massachusetts to compare health insurance coverage and health care access and use for adults before and after the implementation of the health policy changes. To control for underlying trends not related to the reform initiatives, we subtract changes in the outcomes over the same time period for comparison groups of adults who were not affected by the policy changes using a differences-in-differences framework. The analyses are conducted using multiple comparison groups and different time periods as a check on the robustness of the findings. Data Collection/Extraction Methods Nonelderly adults ages 19–64 in the NHIS. Principal Findings We find evidence of the success of the initiatives in New York and Massachusetts at expanding insurance coverage, with the greatest gains reported by the initiative that was broadest in scope—the Massachusetts push toward universal coverage. There is no evidence of improvements in access to care in New York, reflecting the small gains in coverage under that state's reform effort and the narrow focus of the initiative. In contrast, there were significant gains in access to care in Massachusetts, where the impact on insurance coverage was greater and a more comprehensive set of reforms were implemented to improve access to a full array of health care services. The estimated gains in coverage and access to care reported here for Massachusetts were achieved in the early period under health reform, before the state's reform initiative was fully implemented. Conclusions Comprehensive reform initiatives are more successful at addressing gaps in coverage and access to care than are narrower efforts, highlighting the potential gains under national

    The possibility of 85 Kr dating of groundwater is being investigated. The method of gas extraction from 200 to 300 litres of water sample has been developed. The Argon and Krypton mixture, separated from the gas extracted from water, was counted in a 1.5 ml volume proportional counter. The amount of krypton gas in the counter was determined by mass spectrometry. A number of surface and groundwater samples were analyzed indicating an 85 Kr concentration ranging from present atmospheric content (river water) to zero values. 85 Kr 'blank value' was determined to be about 5 per cent of present 85 Kr atmospheric content. For groundwater samples, the mean residence time in the system was calculated assuming the exponential model and known 85 Kr input function. Further improvement of the method should bring higher yield of krypton separation and lower volume of water necessary for analysis. (orig.) [de

  14. Blind-date Conversation Joining

    Full Text Available We focus on a form of joining conversations among multiple parties in service-oriented applications where a client may asynchronously join an existing conversation without need to know in advance any information about it. More specifically, we show how the correlation mechanism provided by orchestration languages enables a form of conversation joining that is completely transparent to clients and that we call 'blind-date joining'. We provide an implementation of this strategy by using the standard orchestration language WS-BPEL. We then present its formal semantics by resorting to COWS, a process calculus specifically designed for modelling service-oriented applications. We illustrate our approach by means of a simple, but realistic, case study from the online games domain.

    Before the Affordable Care Act (ACA), many surveys showed majority support for national health insurance (NHI), also known as single payer; however, little is currently known about views of the ACA's targeted population. Massachusetts residents have had seven years of experience with state health care reform that became the model for the ACA. We surveyed 1,151 adults visiting safety-net emergency departments in Massachusetts in late 2013 on their preference for NHI or the Massachusetts reform and on their experiences with insurance. Most of the patients surveyed were low-income and non-white. The majority of patients (72.0%) preferred NHI to the Massachusetts reform. Support for NHI among those with public insurance, commercial insurance, and no insurance was 68.9%, 70.3%, and 86.3%, respectively (p reform, a reappraisal of the ACA's ability to meet the needs of underserved patients is warranted. © The Author(s) 2015.

  19. Thermoluminescence dating of Hawaiian basalt

    Science.gov (United States)

    May, Rodd James

    1979-01-01

    The thermoluminescence (TL) properties of plagioclase separates from 11 independently dated alkalic basalts 4,500 years to 3.3 million years old and 17 tholeiitic basalts 16 years to 450,000 years old from the Hawaiian Islands were investigated for the purpose of developing a TL dating method for young volcanic rocks. Ratios of natural to artificial TL intensity, when normalized for natural radiation dose rates, were used to quantify the thermoluminescence response of individual samples for age-determination purposes. The TL ratios for the alkalic basalt plagioclase were found to increase with age at a predictable exponential rate that permits the use of the equation for the best-fit line through a plot of the TL ratios relative to known age as a TL age equation. The equation is applicable to rocks ranging in composition from basaltic andesite to trachyte over the age range from about 2,000 to at least 250,000 years before present (B.P.). The TL ages for samples older than 50,000 years have a calculated precision of less than :t 10 percent and a potential estimated accuracy relative to potassium-argon ages of approximately :t 10 percent. An attempt to develop a similar dating curve for the tholeiitic basalts was not as successful, primarily because the dose rates are on the average lower than those for the alkalic basalts by a factor of 6, resulting in lower TL intensities in the tholeiitic basalts for samples of equivalent age, and also because the age distribution of dated material is inadequate. The basic TL properties of the plagioclase from the two rock types are similar, however, and TL dating of tholeiitic basalts should eventually be feasible over the age range 10,000 to at least 200,000 years B.P. The average composition of the plagioclase separates from the alkalic basalts ranges from oligoclase to andesine; compositional variations within this range have no apparent effect on the TL ratios. The average composition of the plagioclase from the tholeiitic

  1. What's the matter with Kansas? Legislative debates over stem cell research in Kansas and Massachusetts.

    Science.gov (United States)

    Stabile, Bonnie

    2009-03-01

    This paper examines the contextual factors shaping legislative debates affecting stem cell research in two states, Kansas and Massachusetts, which both permit therapeutic cloning for stem cell research but markedly vary in their legislative approach to the issue. In Kansas, restrictive legislation was proposed but effectively blocked by research proponents, while in Massachusetts permissive legislation was successfully implemented under the auspices of an act to promote stem cell research. The importance of university and industry involvement is highlighted in each case, as are the roles of enterprising and persistent policy entrepreneurs. Providing a close examination of the policy process attending the cloning debate in these states is intended to contribute to an enhanced understanding of the cloning-policy process as it has played out at the state level, with an eye toward informing legislative debates over related biotechnical advances in the future.

  2. Mandate-Based Health Reform and the Labor Market: Evidence from the Massachusetts Reform*

    Kolstad, Jonathan T.; Kowalski, Amanda E.

    2016-01-01

    We model the labor market impact of the key provisions of the national and Massachusetts “mandate-based” health reforms: individual mandates, employer mandates, and subsidies. We characterize the compensating differential for employer-sponsored health insurance (ESHI) and the welfare impact of reform in terms of “sufficient statistics.” We compare welfare under mandate-based reform to welfare in a counterfactual world where individuals do not value ESHI. Relying on the Massachusetts reform, we find that jobs with ESHI pay $2,812 less annually, somewhat less than the cost of ESHI to employers. Accordingly, the deadweight loss of mandate-based health reform was approximately 8 percent of its potential size. PMID:27037897

    Chronic absenteeism is associated with poorer academic performance and higher attrition in kindergarten to 12th grade (K-12) schools. In prior research, students who were chronically absent generally had fewer employment opportunities and worse health after graduation. We examined the impact that environmental factors surrounding schools have on chronic absenteeism. We estimated the greenness (Normalized Difference Vegetation Index (NDVI)) and fine particulate matter air pollution (PM 2.5 ) within 250 m and 1000 m respectively of each public school in Massachusetts during the 2012-2013 academic year using satellite-based data. We modeled chronic absenteeism rates in the same year as a function of PM 2.5 and NDVI, controlling for race and household income. Among the 1772 public schools in Massachusetts, a 0.15 increase in NDVI during the academic year was associated with a 2.6% ( p value schools.

    2007-03-01

    Full Text Available This article discusses the Massachusetts Afterschool Research Study (MARS. Conducted during 2003-2005, MARS took an in-depth look at program structure and quality in 78 varied programs across Massachusetts, using data sources that included interviews with program directors, afterschool program site observations, school district student data, attendance data, and surveys with afterschool program staff, day school teachers, and afterschool program youth. The MARS study offers many useful insights into what afterschool programs look like, approaches to providing high quality experiences for youth, and the connections between high quality and improved outcomes for the young people attending these programs. The results may be useful to programs, policy makers, and others in the field by deepening our understanding of how youth participation leads to a variety of youth outcomes.

  9. Lower electricity prices and greenhouse gas emissions due to rooftop solar: empirical results for Massachusetts

    International Nuclear Information System (INIS)

    Kaufmann, Robert K.; Vaid, Devina

    2016-01-01

    Monthly and hourly correlations among photovoltaic (PV) capacity utilization, electricity prices, electricity consumption, and the thermal efficiency of power plants in Massachusetts reduce electricity prices and carbon emissions beyond average calculations. PV utilization rates are highest when the thermal efficiencies of natural gas fired power plants are lowest, which reduces emissions of CO 2 and CH 4 by 0.3% relative to the annual average emission rate. There is a positive correlation between PV utilization rates and electricity prices, which raises the implied price of PV electricity by up to 10% relative to the annual average price, such that the average MWh reduces electricity prices by $0.26–$1.86 per MWh. These price reductions save Massachusetts rate-payers $184 million between 2010 and 2012. The current and net present values of these savings are greater than the cost of solar renewable energy credits which is the policy instrument that is used to accelerate the installation of PV capacity. Together, these results suggest that rooftop PV is an economically viable source of power in Massachusetts even though it has not reached socket parity. - Highlights: •Implied price of PV up to 10% greater than the annual average price. •PV saves Massachusetts rate-payers $184 million in 2010–2012. •Annual savings are greater than the cost of solar renewable energy credits. •Savings rise longer lifetime of PV systems and pay period for SREC's shortened. •PV reduces emissions of CO 2 and CH 4 by 0.3% relative to the annual average.

  10. A comparison of Massachusetts and Texas high school biology teachers' attitudes towards the teaching of evolution

    Science.gov (United States)

    Howarth, Richard T.

    Darwin's theory of evolution by natural selection is considered to be the unifying theory for all life sciences (American Association for the Advancement of Science, AAAS, 1990; National Academy of Sciences, 1998; National Research Council, NRC, 1996; National Science Teachers Association, NSTA, 2010a) and as such, the biology topic has been established as a central learning standard by the National Science Education Science Standards (NSES, 2005). The purpose of this study was to compare how Massachusetts and Texas high school biology teachers' attitudes toward the teaching of evolution differ as compared to other biology topics. Texas and Massachusetts are two states that exemplify standards based education yet differ dramatically in their histories surrounding the topic of evolution. A survey was conducted among 217 Massachusetts and 139 Texas in-service high school biology teachers to help provide a sense of the phenomena surrounding biology teachers in respect to how their attitudes towards the teaching of evolution are shaped. Additionally, an open-ended question was asked to help contextualize the results of the survey between teachers of these two states. The findings in this study suggest that community appears to be a powerful persuasive message and socialization experience that shapes the development of attitudes towards evolution for some educators, especially when it is highly intertwined with religion. For biology teachers in the state of Texas, the synergistic result of this relationship has resulted in statistically significant differences in regards to attitudes towards evolution as compared to teachers in Massachusetts. These findings yield implications regarding scientific literacy, student learning, assessment, the quality of science instruction, curriculum, undergraduate biology programs, and the needs of biology teachers in terms of professional development.

Quasi-experimental difference in differences study examining change after reform in the share of procedures performed in safety net hospitals by race/ethnicity and area income, with adjustment for patients' residence, demographics, and comorbidity. State of Massachusetts, United States. Massachusetts residents aged 40-64 as the target beneficiaries of reform and similarly aged residents of New Jersey, New York, and Pennsylvania as the comparison (control) population. Number of knee and hip replacement procedures per 10 000 population and use of safety net hospitals. Procedure counts from state discharge data for 2.5 years before and after reform, and multivariate difference in differences. Poisson regression was used to adjust for demographics, economic conditions, secular time, and geographic factors to estimate the change in procedure rate associated with health reform by race/ethnicity and area income. Before reform, the number of procedures (/10 000) in Massachusetts was lower among Hispanic people (12.9, Preform in Massachusetts was associated with a 4.7% increase. The increase associated with reform was significantly higher among Hispanic people (37.9%, Preform. The reduction was larger among Hispanic people (-6.4%, P<0.001) than white people (-1.0%), and among low income residents (-3.9%, p<0.001) than high income residents (0%). Insurance expansion can help reduce disparities by race/ethnicity but not by income in access to elective surgical care and could shift some elective surgical care away from safety net hospitals. © Hanchate et al 2015.

    Pharmaceutical industry payments to physicians may affect prescribing practices and increase costs if more expensive medications are prescribed. Determine the association between industry payments to physicians and the prescribing of brand-name as compared with generic statins for lowering cholesterol. Cross-sectional linkage of the Part D Medicare prescriptions claims data with the Massachusetts physicians payment database including all licensed Massachusetts physicians who wrote prescriptions for statins paid for under the Medicare drug benefit in 2011. The exposure variable was a physician's industry payments as listed in the Massachusetts database. The outcome was the physician's rate of prescribing brand-name statins. We used linear regression to analyze the association between the intensity of physicians' industry relationships (as measured by total payments) and their prescribing practices, as well as the effects of specific types of payments. Among the 2444 Massachusetts physicians in the Medicare prescribing database in 2011, 899 (36.8%) received industry payments. The most frequent payment was for company-sponsored meals (n = 639 [71.1%]). Statins accounted for 1 559 003 prescription claims; 356 807 (22.8%) were for brand-name drugs. For physicians with no industry payments listed, the median brand-name statin prescribing rate was 17.8% (95% CI, 17.2%-18.4%). For every $1000 in total payments received, the brand-name statin prescribing rate increased by 0.1% (95% CI, 0.06%-0.13%; P brand-name prescribing (P = .004); other forms of payments were not. Industry payments to physicians are associated with higher rates of prescribing brand-name statins. As the United States seeks to rein in the costs of prescription drugs and make them less expensive for patients, our findings are concerning.

    A plume of contaminated groundwater extends from former disposal beds at the Massachusetts Military Reservation's wastewater-treatment plant toward Ashumet Pond, coastal ponds, and Vineyard Sound, Cape Cod, Massachusetts. Treated sewage-derived wastewater was discharged to the rapid-infiltration beds for nearly 60 years before the disposal site was moved to a different location in December 1995. Water-quality samples were collected from monitoring wells, multilevel samplers, and profile borings to characterize the nature and extent of the contaminated groundwater and to observe the water-quality changes after the wastewater disposal ceased. Data are presented here for water samples collected in 2007 from 394 wells (at 121 well-cluster locations) and 780 multilevel-sampler ports (at 42 locations) and in 2006-08 at 306 depth intervals in profile borings (at 20 locations) in and near the treated-wastewater plume. Analyses of these water samples for field parameters (specific conductance, pH, dissolved oxygen and phosphate concentrations, and alkalinity); absorbance of ultraviolet/visible light; and concentrations of nitrous oxide, dissolved organic carbon, methylene blue active substances, selected anions and nutrients, including nitrate and ammonium, and selected inorganic solutes, including cations, anions, and minor elements, are presented in tabular format. The natural restoration of the sand and gravel aquifer after removal of the treated-wastewater source, along with interpretations of the water quality in the treated-wastewater plume, have been documented in several published reports that are listed in the references.

    2009-12-01

    We report on work which has been undertaken towards developing an improved methodology for archaeomagnetic dating of archaeological samples through the use of a dedicated field model. In this talk, we focus on the more general (non-archaeological) implications of our results. Our work has focused on Europe, taking advantage of the better spatial and temporal coverage of available samples. Nevertheless, we model the field globally, using an a priori model (such as, for example, CALS7K) to constrain the field away from the regions of available data. This is advantageous over the use of a local field modelling methodology, as it allows us to examine the physical consequences of structure in our model (for example, in terms of the spectra of the field and secular variation at the core-mantle boundary), and to control possible edge effects in the model, which in a local model might produce an unphysical solution. By focusing on one particular region, we produce models that may not be optimal in terms of global structure, but allow us to investigate the data content in the region where it may provide the most information on core-field evolution. In parallel, we have been expanding the archaeointensity record for Great Britain, towards producing an archaeointensity curve for the UK which could ultimately be used for dating of unoriented samples (such as pot sherds). This new record, combined with other recently acquired high-quality intensity data, allows us to consider the evolution of global geomagnetic field strength in parallel with a good model of directional measurements; from 1590, the GUFM model is appropriate. Recent attempts to determine global intensity variation have used all available data (some of uncertain quality) to quantify variations in field strength. By instead focusing on a more limited dataset of known quality, we are able to examine intensity trends in greater detail. We present evidence that the intensity of the field was higher prior to 1840 than

  20. The impact of state intervention on "underperforming" schools in Massachusetts: Implications for policy and practice.

    Directory of Open Access Journals (Sweden)

    Patrick J. McQuillan

    2008-09-01

    Full Text Available Since passage of the federal No Child Left Behind Act (NCLB in 2002, state departments of education across the U.S. have been busy creating or modifying school accountability systems to meet NCLB guidelines. Ultimately, NCLB seeks to have all public school students proficient in English/Language Arts and mathematics by 2014. To identify schools in danger of not meeting this goal, states must establish student performance benchmarks and identify schools not making adequate yearly progress (AYP. Those consistently failing to make AYP can be ordered into "radical restructuring," which may include having the state intervene in running the school (U. S. Department of Education, 2002. Given these NCLB provisions and the growing number of schools not meeting AYP, the number of state interventions in low-performing schools will certainly increase. Accordingly, this article explores two questions about state-led interventions. First, how have teachers and administrators in underperforming schools in Massachusetts perceived state intervention? In addition, based on their perceptions, what might be done to make the process more effective? At three schools that experienced interventions from the Massachusetts Department of Education, a qualitative study explored the process of state intervention. A survey to principals in 22 of the 23 schools deemed underperforming by the state between 2000 and 2004 supplemented the in-depth qualitative work. Drawing on these mixed methods data sources, this article offers a series of proposals aimed at informing future state interventions in Massachusetts and elsewhere.

  1. Barriers to contraceptive access after health care reform: experiences of young adults in Massachusetts.

    To explore how Massachusetts' 2006 health insurance reforms affected access to sexual and reproductive health (SRH) services for young adults. We conducted 11 focus group discussions across Massachusetts with 89 women and men aged 18 to 26 in 2009. Most young adults' primary interaction with the health system was for contraceptive and other SRH services, although they knew little about these services. Overall, health insurance literacy was low. Parents were primary decision makers in health insurance choices or assisted their adult children in choosing a plan. Ten percent of our sample was uninsured at the time of the discussion; a lack of knowledge about provisions in Chapter 58 rather than calculated risk analysis characterized periods of uninsurance. The dynamics of being transitionally uninsured, moving between health plans, and moving from a location defined by insurance companies as the coverage area limited consistent access to contraception. Notably, staying on parents' insurance through extended dependency, a provision unique to the post-reform context, had implications for confidentiality and access. Young adults' access to and utilization of contraceptive services in the post-reform period were challenged by unanticipated barriers related to information and privacy. The experience in Massachusetts offers instructive lessons for the implementation of national health care reform. Young adult-targeted efforts should address the challenges of health service utilization unique to this population. Copyright © 2015 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Today MACRIS holds over 206,000 records from the 351 towns and cities across the Commonwealth. Since 2004, a selection of the more than 150 MACRIS fields has been available online at mhcmacris. net. MACRIS is widely used by independent consultants preparing project review files, by MHC staff in its regulatory responsibilities, by local historical commissions monitoring threats to their communities, as well as by scholars, historical organizations, genealogists, property owners, reporters, and the general public interested in the history of the built environment. In 2016 MACRIS began migration off of its three-decade old Pick multivalue database to SQL Server, and in 2017, the first redesign of its thirteen-year old web interface should start to improve usability. Longer-term improvements have the goal of standardizing terminology and ultimately bringing interoperability with other heritage databases closer to reality.

    Education and practice partnerships are key to effective academic program design and implementation in a time of decreasing supply and increasing demands on the nursing profession. An integrated education/practice competency model can positively impact patient safety, improve patient care, increase retention, and ensure a sufficient and competent nursing workforce, which is paramount to survival of the health care system. Through the contributions of nursing leaders from the broad spectrum of nursing and industry organizations within the state, the Massachusetts Nurse of the Future project developed a competency-based framework for the future design of nursing educational programs to meet current and future practice needs. The Massachusetts Nurse of the Future Nursing Core Competencies(©) expand on the Institute of Medicine's core competencies for all health care professionals and the Quality and Safety Education for Nurses competencies for quality and safety to define the expectations for all professional nurses of the future. The Massachusetts Nurse of the Future Nursing Core Competencies define the knowledge, attitude, and skills required as the minimal expectations for initial nursing practice following completion of a prelicensure professional nursing education program. These competencies are now being integrated into new models for seamless, coordinated nursing curriculum and transition into practice within the state and beyond. Copyright © 2011 Elsevier Inc.

    Objective Evaluate Massachusetts pediatricians' views toward school-based body mass index screening since its implementation. Methods Survey of 286 members of the Massachusetts Chapter of the American Academy of Pediatrics on attitudes toward screening and perceived impact on clinical practice. Results Overall, 36.3% supported screening, with suburban or rural pediatricians significantly less likely (vs urban) to indicate support. Less than 10% of pediatricians agreed or strongly agreed that screening improved communication with schools (4.2%), communication with families (8.9%), or helped them care for patients (7.0%), with suburban or rural pediatricians significantly less likely to agree. Most pediatricians reported contact from patients regarding screening (59.4%) and identifying concerns from patients regarding screening during office visits (60.4%), including bullying and self-esteem. Suburban or rural pediatricians were significantly more likely to report patient contact and concerns related to screening. Conclusions Support for school-based body mass index screening is low among Massachusetts pediatricians, particularly among suburban and rural pediatricians. © The Author(s) 2015.

    The U.S. Geological Survey conducted a high-resolution geophysical survey within Red Brook Harbor, Massachusetts, from September 28 through November 17, 2009. Red Brook Harbor is located on the eastern edge of Buzzards Bay, south of the Cape Cod Canal. The survey area was approximately 7 square kilometers, with depths ranging from 0 to approximately 10 meters. Data were collected aboard the U.S. Geological Survey Research Vessel Rafael. The research vessel was equipped with a 234-kilohertz interferometric sonar system to collect bathymetry and backscatter data, a dual frequency (3.5- and 200-kilohertz) compression high-intensity radar pulse seismic reflection profiler to collect subbottom data, a sound velocity profiler to acquire speed of sound within the water column, and a sea floor sampling device to collect sediment samples, video, and photographs. The survey was part of an ongoing cooperative effort between the U.S. Geological Survey and the Massachusetts Office of Coastal Zone Management to map the geology of the Massachusetts inner continental shelf. In addition to inclusion within the cooperative geologic mapping effort, these data will be used to assess the shallow-water mapping capability of the geophysical systems deployed for this project, with an emphasis on identifying resolution benchmarks for the interferometric sonar system.

  6. Estimated hydrologic budgets of kettle-hole ponds in coastal aquifers of southeastern Massachusetts

    Kettle-hole ponds in southeastern Massachusetts are in good hydraulic connection to an extensive coastal aquifer system that includes the Plymouth-Carver aquifer system on the mainland and aquifers underlying Cape Cod. The ponds receive water from, and contribute water to, the underlying glacial aquifer; ponds also receive water from precipitation and lose water to evaporation from the pond surface. Some ponds are connected to surface-water drainage systems and receive water from or contribute water to streams or adjacent wetlands. The Massachusetts Department of Environmental Protection currently (2011) is developing Total Maximum Daily Loads of phosphorus for the freshwater ponds in the region to maintain the health of pond ecosystems; the amounts and sources of water fluxes into and out of the ponds are important factors in determining the amount of phosphorus that can be assimilated into a pond. To assist in this effort, the U.S. Geological Survey used groundwater-flow models of the coastal aquifer system to estimate hydrologic budgets-including inflows and outflows from the aquifer system and adjacent streams and wetlands, and recharge from precipitation-for 425 ponds in southeastern Massachusetts.

    Dating violence during adolescence negatively influences concurrent psychosocial functioning, and has been linked with an increased likelihood of later intimate partner violence. Identifying who is most vulnerable for this negative outcome can inform the development of intervention practices addressing this problem. The two goals of this study were to assess variations in the prevalence of dating violence across different measures of sexual minority status (e.g., sexual minority identity or same-sex sexual behavior), and to assess whether this association was mediated by bullying, the number of sexual partners, binge drinking or aggressive behaviors. These goals were assessed by employing the Massachusetts Youth Risk Behavior Survey (N = 12,984), a regionally representative sample of youth ages 14-18. In this sample, a total of 540 girls and 323 boys reported a non-heterosexual identity, and 429 girls and 230 boys reported having had one or more same-sex sexual partners. The results generally supported a higher prevalence of dating violence among sexual minority youth. This vulnerability varied considerably across gender, sexual minority identity and the gender of sexual partners, but generally persisted when accounting for the mediating variables. The findings support investigating dating violence as a mechanism in the disparities between sexual minority and heterosexual youth, and the importance of addressing sexual minority youth specifically in interventions targeting dating violence.

  16. Reservoir effects in radiocarbon dating

    International Nuclear Information System (INIS)

    Head, M.J.

    1997-01-01

    Full text: The radiocarbon dating technique depends essentially on the assumption that atmospheric carbon dioxide containing the cosmogenic radioisotope 14 C enters into a state of equilibrium with all living material (plants and animals) as part of the terrestrial carbon cycle. Terrestrial reservoir effects occur when the atmospheric 14 C signal is diluted by local effects where systems depleted in 14 C mix with systems that are in equilibrium with the atmosphere. Naturally, this can occur with plant material growing close to an active volcano adding very old CO 2 to the atmosphere (the original 14 C has completely decayed). It can also occur in highly industrialised areas where fossil fuel derived CO 2 dilutes the atmospheric signal. A terrestrial reservoir effect can occur in the case of fresh water shells living in rivers or lakes where there is an input of ground water from springs or a raising of the water table. Soluble bicarbonate derived from the dissolution of very old limestone produces a 14 C dilution effect. Land snail shells and stream carbonate depositions (tufas and travertines) can be affected by a similar mechanism. Alternatively, in specific cases, these reservoir effects may not occur. This means that general interpretations assuming quantitative values for these terrestrial effects are not possible. Each microenvironment associated with samples being analysed needs to be evaluated independently. Similarly, the marine environment produces reservoir effects. With respect to marine shells and corals, the water depth at which carbonate growth occurs can significantly affect quantitative 14 C dilution, especially in areas where very old water is uplifted, mixing with top layers of water that undergo significant exchange with atmospheric CO 2 . Hence, generalisations with respect to the marine reservoir effect also pose problems. These can be exacerbated by the mixing of sea water with either terrestrial water in estuaries, or ground water where

So far we have provided a chronology for seven important Indian archaeological sites. The dated cultures include: 1) the Ochre Colour Ware culture, 2) the Pre-Harappan culture, 3) the megalithic culture and 4) the Painted Grey Ware culture. A complete survey of recently measured TL dates are presented in a model format similar to that used in Radiocarbon. (author)

  18. AMS Radiocarbon Dating at Notre Dame

    2014-09-01

    Current development of a local radiocarbon dating method using Accelerator Mass Spectrometry (AMS) at the University of Notre Dame seeks to provide sensitive, reproducible, and accurate measurements for future interdisciplinary projects. While AMS has been the premier radiocarbon dating method for a few decades, repurposing Notre Dame's FN Tandem accelerator for radiocarbon dating has provided many unique challenges. Experiments have shown radiocarbon dating possible and reproducible using the FN Tandem accelerator, found optimal settings for said accelerator, and established sensitivity limits comparable to dedicated radiocarbon dating facilities. In addition, there is ongoing work to create a local chemistry lab to convert organic artifacts into graphite samples to be dated locally. Once the chemistry side has been completed, several artifacts from the IAEA's radiocarbon intercomparison have been procured. Dating these previously studied artifacts will provide an additional measure on the accuracy and repeatability of both the accelerator and chemical treatment. Provided that these IAEA artifacts are dated successfully, exciting projects will ensue, such as the authentication of artwork and dating of anthropological samples.

  20. Estimating costs of low-level radioactive waste disposal alternatives for the Commonwealth of Massachusetts

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-01

    This report was prepared for the Commonwealth of Massachusetts by the Idaho National Engineering Laboratory, National Low-Level Waste Management Program. It presents planning life-cycle cost (PLCC) estimates for four sizes of in-state low-level radioactive waste (LLRW) disposal facilities. These PLCC estimates include preoperational and operational expenditures, all support facilities, materials, labor, closure costs, and long-term institutional care and monitoring costs. It is intended that this report bc used as a broad decision making tool for evaluating one of the several complex factors that must be examined when deciding between various LLRW management options -- relative costs. Because the underlying assumptions of these analyses will change as the Board decides how it will manage Massachusett`s waste and the specific characteristics any disposal facility will have, the results of this study are not absolute and should only be used to compare the relative costs of the options presented. The disposal technology selected for this analysis is aboveground earth-mounded vaults. These vaults are reinforced concrete structures where low-level waste is emplaced and later covered with a multi-layered earthen cap. The ``base case`` PLCC estimate was derived from a preliminary feasibility design developed for the Illinois Low-Level Radioactive Waste Disposal Facility. This PLCC report describes facility operations and details the procedure used to develop the base case PLCC estimate for each facility component and size. Sensitivity analyses were performed on the base case PLCC estimate by varying several factors to determine their influences upon the unit disposal costs. The report presents the results of the sensitivity analyses for the five most significant cost factors.

    Assisted Reproductive Technology (ART) includes fertility procedures where both egg and sperm are handled in the lab. ART use has increased considerably in recent years, accounting for 47,090 livebirths in the U.S. in 2010. ART increases the probability of multiple gestation births, which are at higher risks than singletons for adverse outcomes. Additionally, ART is associated with a greater risk of complications during pregnancy, labour, and delivery, and increased risk of adverse perinatal outcomes in singleton births. We merged Florida and Massachusetts birth records from 2004-06 with the National ART Surveillance System (NASS) and using NASS as the gold standard, calculated sensitivity, specificity, and positive predictive value (PPV) of ART reporting on the birth certificates by maternal, infant, and hospital characteristics. We fit random-effects logistic regression models to evaluate simultaneously the association of ART reporting with these predictors while accounting for correlation among births occurring in the same hospital. Sensitivity of ART reporting on the birth certificate was 28.9% in Florida and 41.4% in Massachusetts. Specificity was >99% in both states. PPV was 45.5% in Florida and 54.6% in Massachusetts. The odds of ART reporting varied by state and by several maternal and delivery characteristics including age, parity, history of fetal loss, plurality, race/Hispanic ethnicity, delivery payment source, pre-existing conditions, and complications during pregnancy or labour and delivery. There was significant under-reporting of ART procedures on the birth certificates. Using data on ART births identified only from birth certificates yields a biased sample of the population of ART births. © 2014 John Wiley & Sons Ltd.

    To determine whether hospital processes and hospital quality associated with the care of femoral neck fractures were significantly altered by the implementation of healthcare reform in Massachusetts. Pre-post retrospective study. Massachusetts Statewide Inpatient Dataset (SID). Patients treated for femoral neck fracture (n = 23,485) in the periods prehealth (2003-06) and posthealth reform (2008-10). Differences in hospital processes for fracture care and quality measures were assessed for the periods before and after health reform. Differences in hospital processes for fracture care (type of surgical intervention, length of stay, and discharge disposition) and quality metrics [mortality, complications, re-operation, and failure to rescue (FTR)] in the periods before and after health reform were assessed using regression techniques to adjust for differences in case mix and the type of surgical intervention. There were no significant differences in the type of surgical intervention performed prereform and postreform (P = 0.27). After adjustment for case mix and surgical intervention, length of stay was significantly reduced {regression coefficient -0.07 [95% confidence interval (CI), -0.09 to -0.06]} as were the odds of FTR [odds ratio 0.73 (95% CI, 0.59-0.92)]. Discharges to skilled nursing facilities significantly increased in the postreform period [relative risk ratio 1.15 (95% CI, 1.03-1.30)]. Findings associated with FTR were driven by changes in the detection of surveillance sensitive complications. Health reform in Massachusetts led to no clinically meaningful differences in hospital processes for femoral neck fracture care. Although some differences in quality measures were noted, these cannot necessarily be attributed to health care reform.

    Inadequate access to care for mentally ill children and their families is a persistent problem in the United States. Although promotion of pediatric primary care clinicians (PCCs) in detection, management, and coordination of child mental health care is a strategy for improving access, limitations in training, time, and specialist availability represent substantial barriers. The Massachusetts Child Psychiatry Access Project (MCPAP), publicly funded with 6 regional consultation teams, provides Massachusetts PCCs with rapid access to child psychiatry expertise, education, and referral assistance. Data collected from MCPAP teams measured participation and utilization over 3.5 years from July 1, 2005, to December 31, 2008. Data were analyzed for 35,335 encounters. PCC surveys assessed satisfaction and impact on access to care. The MCPAP enrolled 1341 PCCs in 353 practices covering 95% of the youth in Massachusetts. The MCPAP served 10,114 children. Practices varied in their utilization of the MCPAP, with a mean of 12 encounters per practice per quarter (range: 0-245). PCCs contacted the MCPAP for diagnostic questions (34%), identifying community resources (27%), and consultation regarding medication (27%). Provider surveys revealed improvement in ratings of access to child psychiatry. The rate of PCCs who reported that they are usually able to meet the needs of psychiatric patients increased from 8% to 63%. Consultations were reported to be helpful by 91% of PCCs. PCCs have used and value a statewide system that provides access to teams of psychiatric consultants. Access to child mental health care may be substantially improved through public health interventions that promote collaboration between PCCs and child mental health specialists.

    Since 2005, after a pilot program, the Massachusetts Child Psychiatry Access Project (MCPAP) has provided point-of-care psychiatry expertise and referral assistance by telephone to primary care providers. We examined its adoption and use and the practice characteristics associated with different adoption timelines and use patterns. We merged data on calls to MCPAP in 2005 to 2011 with practice data (enrollment year, panel size, regional team assignment). We categorized practices' days from enrollment to first call (adoption) (0-100, 101-365, > 365 days) and quartile of call frequency (use) (annual highest, middle, and lowest quartiles of number of calls per 1000 empanelled patients). We determined associations between adoption and use and practice characteristics using multivariate models. Among 285 practices, adoption and use varied: 55% called 0 to 100 days from enrollment and 16% called >365 days from enrollment. Practices in the highest quartile of use made a mean 15.5 calls/year per 1000 patients, whereas the lowest quartile made 0.4 calls/year per 1000 patients. Adoption within 100 days was associated with enrollment during or after 2007 (odds ratio [OR] 4.09, 95% confidence interval [CI] 2.23-7.49) and assignment to the team at the pilot site (OR 4.42, 95% CI 2.16-9.04 for central Massachusetts). Highest-quartile use was associated with team assignment (OR 3.58, 95% CI 1.86-6.87 for central Massachusetts) and panel size (OR 0.10, 95% CI 0.03-0.31 for ≥ 10,000 vs < 2000 patients). Adoption and use of MCPAP varied widely. Timing of enrollment, assignment to the team from the program's pilot site, and panel size were associated with patterns of adoption and use. Findings may help other programs design effective implementation strategies. Copyright © 2015 by the American Academy of Pediatrics.

    Various studies have reported the physical and mental health benefits from exposure to "green" neighborhoods, such as proximity to neighborhoods with trees and vegetation. However, no studies have explicitly assessed the association between exposure to "green" surroundings and cognitive function in terms of student academic performance. This study investigated the association between the "greenness" of the area surrounding a Massachusetts public elementary school and the academic achievement of the school's student body based on standardized tests with an ecological setting. Researchers used the composite school-based performance scores generated by the Massachusetts Comprehensive Assessment System (MCAS) to measure the percentage of 3rd-grade students (the first year of standardized testing for 8-9 years-old children in public school), who scored "Above Proficient" (AP) in English and Mathematics tests (Note: Individual student scores are not publically available). The MCAS results are comparable year to year thanks to an equating process. Researchers included test results from 2006 through 2012 in 905 public schools and adjusted for differences between schools in the final analysis according to race, gender, English as a second language (proxy for ethnicity and language facility), parent income, student-teacher ratio, and school attendance. Surrounding greenness of each school was measured using satellite images converted into the Normalized Difference Vegetation Index (NDVI) in March, July and October of each year according to a 250-meter, 500-meter, 1,000-meter, and 2000-meter circular buffer around each school. Spatial Generalized Linear Mixed Models (GLMMs) estimated the impacts of surrounding greenness on school-based performance. Overall the study results supported a relationship between the "greenness" of the school area and the school-wide academic performance. Interestingly, the results showed a consistently positive significant association between the

    The date palm plays a very significant role in Tunisia in term of culture as well as social, economic and ecological aspects. The production of the dates which is estimated to 120.000 tons/year ensures the principal income for the majority of the oasis population of the South of Tunisia and constitutes the basis for agricultural, industrial, commercial and tourist activities, offering million of working days. The date palm is cultivated mainly for the production of dates which are consumed locally or also exported abroad but for its by-products (food of the cattle, wind breaks, fuel, construction) which are marketed and/ or used in the everyday life thus taking part in the sedentarisation of the populations and the maintenance of a fragile socio-economic balance. The date moth, Ectomyelois ceratoniae Zell. ( L will epidoptera, Pyralidae) is without question the most significant problem of the Tunisian date palm. The infestation of dates in the field and in the storage and packing houses enormously depreciates the marketable quality of dates and risk to compromise exports in particular those of the variety Deglet Nour. rates of infestations of about 20% are often recorded in Tunisia where as the European standards require rates lower than 5%. In Tunisia the desinsectisation of dates is done until now by the use of methyl bromide, its high toxicity substantially reduces the duration of date treatment, and consequently the treated volumes. The replacement of this product becomes an urgent need its use will not be authorized by 2015. Within the framework of a agreement between the Regional Research Center in Oasis Agriculture (CRRAO), The Interprofessional Grouping of Fruits (GIF), and the Italian Company IMETEC, the use one of micro-waves as a desinsectisation method of dates was evaluated. The results of this present work showed that total desinsectisation of dates by microwaves can be obtained only with homogeneous dates in term of water content. Total

    The case of Hanna Porn affords an opportunity to examine how the laws that led to the abolition of midwifery in Massachusetts evolved and were applied to the midwife whose case set the state legal precedent. Mrs Porn served primarily a Finnish-Swedish clientele of wives of laborers. The outcomes of the births she attended appear to have been positive, and she maintained a neonatal mortality rate of less than half that of local physicians. She also repeatedly defied court orders to stop practicing. Her case exemplifies the efforts that occurred nationally to abolish midwifery in the United States.

    The Albany 1 0 x 2 0 Quadrangle, Massachusetts, New York, Connecticut, Vermont, and New Hampshire, was evaluated to a depth of 1500 m for uranium favorability using National Uranium Resource Evaluation criteria. Areas of favorable geology and aeroradioactivity anomalies were examined and sampled. Most Triassic and Jurassic sediments in the Connecticut Basin, in the central part of the quadrangle, were found to be favorable for sandstone uranium deposits. Some Precambrian units in the southern Green Mountains of Vermont were found favorable for uranium deposits in veins in metamorphic rocks

    Full Text Available In June 1993, Governor William Weld signed into law the Massachusetts Education Reform Act (MERA. MERA greatly increased the state role both in funding public education and in guiding the local educational process. The state’s role changed to incorporate setting curriculum frameworks and holding schools accountable for student performance. Because MERA was designed to be a systemic reform of education, all of the various state activities and policies needed to fit together into a coherent whole based on state educational standards.

  11. Performance Results for Massachusetts and Rhode Island Deep Energy Retrofit Pilot Community

    2014-03-01

    Between December, 2009 and December, 2012, 42 deep energy retrofit (DER) projects were completed through a pilot program sponsored by National Grid and conducted in Massachusetts and Rhode Island. Thirty-seven of these projects were comprehensive retrofits while five were partial DERs, meaning that high performance retrofit was implemented for a single major enclosure component or a limited number of major enclosure components. Building Science Corporation developed a consistent "package" of measures in terms of the performance targeted for major building components. Based on the community experience, this DER package is expected to result in yearly source energy use near 110 MMBtu/year or approximately 40% below the Northeast regional average.

  12. Increased use of the emergency department after health care reform in Massachusetts.

    With implementation of the Patient Protection and Affordable Care Act, 30 million individuals are predicted to gain access to health insurance. The experience in Massachusetts, which implemented a similar reform beginning in 2006, should provide important lessons about the effect of health care reform on emergency department (ED) utilization. Our objective is to understand the extent to which Massachusetts health care reform was associated with changes in ED utilization. We compared changes in ED utilization at the population level for individuals from areas of the state that were affected minimally by health care reform with those from areas that were affected the most, as well as for those younger than 65 years and aged 65 years or older. We used a difference-in-differences identification strategy to compare rates of ED visits in the prereform period, during the reform, and in the postreform period. Because we did not have population-level data on insurance status, we estimated area-level insurance rates by using the percentage of actual visits made during each period by individuals with insurance. We studied 13.3 million ED visits during 2004 to 2009. Increasing insurance coverage in Massachusetts was associated with increasing use of the ED; these results were consistent across all specifications, including the younger than 65 years versus aged 65 years or older comparison. Depending on the model used, the implementation of health care reform was estimated to result in an increase in ED visits per year of between 0.2% and 1.2% within reform and 0.2% and 2.2% postreform compared with the prereform period. The implementation of health care reform in Massachusetts was associated with a small but consistent increase in the use of the ED across the state. Whether this was due to the elimination of financial barriers to seeking care in the ED, a persistent shortage in access to primary care for those with insurance, or some other cause is not entirely clear and will

    At the request of the US Department of Energy (DOE), a team from Oak Ridge National Laboratory conducted a radiological survey at the Porter Street City Park, Beverly, Massachusetts. The survey was performed in May 1991. The purpose of the survey was to determine if uranium from work performed under government contract at the former Ventron facility had migrated off-site to neighboring areas. The survey included a surface gamma scan and the collection of soil samples for radionuclide analyses. Results of the survey demonstrated no radionuclide concentrations or radiation measurements in excess of the DOE Formerly Utilized Sites Remedial Action Program guidelines

  16. Obtaining Streamflow Statistics for Massachusetts Streams on the World Wide Web

    Science.gov (United States)

    Ries, Kernell G.; Steeves, Peter A.; Freeman, Aleda; Singh, Raj

    2000-01-01

    A World Wide Web application has been developed to make it easy to obtain streamflow statistics for user-selected locations on Massachusetts streams. The Web application, named STREAMSTATS (available at http://water.usgs.gov/osw/streamstats/massachusetts.html ), can provide peak-flow frequency, low-flow frequency, and flow-duration statistics for most streams in Massachusetts. These statistics describe the magnitude (how much), frequency (how often), and duration (how long) of flow in a stream. The U.S. Geological Survey (USGS) has published streamflow statistics, such as the 100-year peak flow, the 7-day, 10-year low flow, and flow-duration statistics, for its data-collection stations in numerous reports. Federal, State, and local agencies need these statistics to plan and manage use of water resources and to regulate activities in and around streams. Engineering and environmental consulting firms, utilities, industry, and others use the statistics to design and operate water-supply systems, hydropower facilities, industrial facilities, wastewater treatment facilities, and roads, bridges, and other structures. Until now, streamflow statistics for data-collection stations have often been difficult to obtain because they are scattered among many reports, some of which are not readily available to the public. In addition, streamflow statistics are often needed for locations where no data are available. STREAMSTATS helps solve these problems. STREAMSTATS was developed jointly by the USGS and MassGIS, the State Geographic Information Systems (GIS) agency, in cooperation with the Massachusetts Departments of Environmental Management and Environmental Protection. The application consists of three major components: (1) a user interface that displays maps and allows users to select stream locations for which they want streamflow statistics (fig. 1), (2) a data base of previously published streamflow statistics and descriptive information for 725 USGS data

    Gridded multibeam bathymetry covers approximately 10.4 square kilometers of sea floor in the vicinity of Cross Rip Channel in Nantucket Sound, offshore southeastern Massachusetts. Although originally collected for charting purposes during National Oceanic and Atmospheric Administration hydrographic survey H12007, these acoustic data, and the sea-floor sediment sampling and bottom photography stations subsequently occupied to verify them, show the composition and terrain of the seabed and provide information on sediment transport and benthic habitat. This report is part of an expanding series of cooperative studies by the U.S. Geological Survey, National Oceanic and Atmospheric Administration, and Massachusetts Office of Coastal Zone Management that provide a fundamental framework for research and resource-management activities (for example, windfarms, pipelines, and dredging) along the inner continental shelf offshore of Massachusetts.

    2014-01-01

    Objectives To analyse changes in overall readmission rates and disparities in such rates, among patients aged 18-64 (those most likely to have been affected by reform), using all payer inpatient discharge databases (hospital episode statistics) from Massachusetts and two control states (New York and New Jersey). Design Difference in differences analysis to identify the post-reform change, adjusted for secular changes unrelated to reform. Setting US hospitals in Massachusetts, New York, and New Jersey. Participants Adults aged 18-64 admitted for any cause, excluding obstetrical. Main outcome measure Readmissions at 30 days after an index admission. Results After adjustment for known confounders, including age, sex, comorbidity, hospital ownership, teaching hospital status, and nurse to census ratio, the odds of all cause readmission in Massachusetts was slightly increased compared with control states post-reform (odds ratio 1.02, 95% confidence interval 1.01 to 1.04, P<0.05). Racial and ethnic disparities in all cause readmission rates did not change in Massachusetts compared with control states. In analyses limited to Massachusetts only, there were minimal overall differences in changes in readmission rates between counties with differing baseline uninsurance rates, but black people in counties with the highest uninsurance rates had decreased odds of readmission (0.91, 0.84 to 1.00) compared with black people in counties with lower uninsurance rates. Similarly, white people in counties with the highest uninsurance rates had decreased odds of readmission (0.96, 0.94 to 0.99) compared with white people in counties with lower uninsurance rates. Conclusions In the United States, and in Massachusetts in particular, extending health insurance coverage alone seems insufficient to improve readmission rates. Additional efforts are needed to reduce hospital readmissions and disparities in this outcome. PMID:24687184

  7. Ambiguity and violence in adolescent dating relationships.

    Science.gov (United States)

    Draucker, Claire Burke; Martsolf, Donna; Stephenson, Pam Shockey

    2012-08-01

    Little is known about dyadic processes that lead to adolescent dating violence. The purpose of this study was to examine the phenomenon of relationship ambiguity in adolescent dating relationships to better understand how ambiguity contributes to violence and aggression between dating partners. Data were drawn from 88 narratives of young adults who had participated in a study on adolescent dating violence. Interpretive phenomenology was used to produce an in-depth description of the phenomenon of relationship ambiguity. Relationship ambiguity results in differing expectations between partners regarding closeness and intimacy, fidelity, and obligation. These differences lead to conflicts that set the stage for violence and aggression in adolescent dating relationships. A series of recommendations for clinicians working with adolescents are presented. © 2012 Wiley Periodicals, Inc.

    2017-08-01

    Immigrants' perceptions of affordability of insurance and knowledge of insurance after health reform are unknown. We conducted face-to-face surveys with a convenience sample of 1124 patients in three Massachusetts safety net Emergency Departments after the Massachusetts health reform (August 2013-January 2014), comparing immigrants and non-immigrants. Immigrants, as compared to non-immigrants, reported more concern about paying premiums (30 vs. 11 %, p = 0.0003) and about affording the current ED visit (38 vs. 22 %, p reform, raising concern about potential disparities under the Affordable Care Act that is based on the MA reform.

    1997-02-01

    The US Nuclear Regulatory Commission (NRC) has prepared this Environmental Assessment (EA) to evaluate environmental issues associated with the renewal of licenses issued by NRC for facilities operated by Nuclear Metals, Inc. (NMI) in Concord, Massachusetts. By renewing the licenses, NRC proposes to allow the continuation of ongoing operations involving radioactive materials at NMI's facilities. This EA focuses on the potential impacts related to air emissions at NMI during normal (incident-free) operations and accidental releases. Findings indicate that there are only two areas of potential concern. First, modeling results for sulfur dioxide (SO 2 ) emissions from the boilers during normal operations indicate that the potential exists for exceeding the short-term National Ambient Air Quality Standards (NAAQS). NMI is prepared to undertake mitigative action to prevent potential exceedances of the short-term SO 2 NAAQS, and the Massachusetts Department of Environmental Protection is prepared to resolve the issue via a permit/approval change or through a Consent Order. Second, in the unlikely event of a severe fire, predicted sulfuric acid (H 2 SO 4 ) concentrations based on conservative (upper bound) modeling exceed the Emergency Response Planning Guideline (ERPG) levels. NMI has committed to NRC to give a briefing for local emergency response officials regarding the potential for an accidental H 2 SO 4 release

    2007-08-01

    A study of water quality, land use, and population variations over the past three decades was conducted in eastern Massachusetts to examine the impact of urban sprawl on water quality using geographic information system and statistical analyses. Since 1970, eastern Massachusetts has experienced pronounced urban sprawl, which has a substantial impact on water quality. High spatial correlations are found between water quality indicators (especially specific conductance, dissolved ions, including Ca, Mg, Na, and Cl, and dissolved solid) and urban sprawl indicators. Urbanized watersheds with high population density, high percentage of developed land use, and low per capita developed land use tended to have high concentrations of water pollutants. The impact of urban sprawl also shows clear spatial difference between suburban areas and central cities: The central cities experienced lower increases over time in specific conductance concentration, compared to suburban and rural areas. The impact of urban sprawl on water quality is attributed to the combined effects of population and land-use change. Per capita developed land use is a very important indicator for studying the impact of urban sprawl and improving land use and watershed management, because inclusion of this indicator can better explain the temporal and spatial variations of more water quality parameters than using individual land use or/and population density.

    This report presents results of marine studies conducted by the U.S. Geological Survey (USGS) during the summers of 1975 and 1976 in eastern Rhode Island Sound and Vineyard Sound (fig. 1) located off the southeastern coast of Massachusetts. The study was made in cooperation with the Massachusetts Department of Public Works and the New England Division of the U.S. Army Corps of Engineers. It covered an area of the Atlantic Inner Continental Shelf between latitude 41 deg 12' and 41 deg 33'N, and between longitude 70 deg 37' and 71 deg 15'W (see index map). Major objectives included assessment of sand and gravel resources, environmental impact evaluation both of offshore mining of these resources and of offshore disposal of solid waste and dredge spoil material, identification and mapping of the offshore geology, and determination of the geologic history of this part of the Inner Shelf. A total of 670 kilometers (km) of closely spaced high-resolution seismic-reflection profiles, 224 km of side-scan sonar data, and 16 cores totaling 90 meters (m) of recovered sediment, were collected during the investigation. This report is companion to geologic maps published for Cape Cod Bay (Oldale and O'Hara, 1975) and Buzzards Bay, Mass. (Robb and Oldale, 1977).

    The Massachusetts Institute of Technology (MIT) reactor (MITR-II), based in Cambridge, Massachusetts, is a research reactor designed primarily for experiments using neutron beam and in-core irradiation facilities. It delivers a neutron flux comparable to current LWR power reactors in a compact 6 MW core using Highly Enriched Uranium (HEU) fuel. In the framework of its non-proliferation policies, the international community presently aims to minimize the amount of nuclear material available that could be used for nuclear weapons. In this geopolitical context, most research and test reactors both domestic and international have started a program of conversion to the use of Low Enriched Uranium (LEU) fuel. A new type of LEU fuel based on a mixture of uranium and molybdenum (UMo) is expected to allow the conversion of compact high performance reactors like the MITR-II. This report presents the results of steady state neutronic safety analyses for conversion of MITR-II from the use of HEU fuel to the use of U-Mo LEU fuel. The objective of this work was to demonstrate that the safety analyses meet current requirements for an LEU core replacement of MITR-II.

    To determine levels of families' satisfaction and anxiety associated with the early hearing detection and intervention (EHDI) process in Massachusetts, and to assess the relationship between a child's hearing status and levels of family satisfaction. Surveys were mailed to families whose infants (a) passed their initial hearing screening (Group 1), (b) did not pass their initial screening but subsequently passed an outpatient rescreen or diagnostic evaluation (Group 2), or (c) were identified with permanent hearing loss (Group 3). Survey instruments measured families' satisfaction and anxiety associated with each stage of the EHDI process. Of the 4,138 families surveyed, 1,106 (27%) responded. Families reported satisfaction with screening services (Group 1 = 88%; Group 2 = 86%; Group 3 = 75%), and few reported anxiety prior to the hearing screening (Group 1= 4%; Group 2 = 15%; Group 3 = 19%). Among families requiring retesting services, 97% of Group 2 and 87% of Group 3 families were satisfied. Among Group 3 families, 94% reported satisfaction with the care their audiologist was providing, and 79% were satisfied with their early intervention services overall. Families reported satisfaction with the EHDI services they received in Massachusetts and expressed strong support for the universal newborn hearing screening initiative.

    2015-01-01

    Objectives To assess the Massachusetts Benchmark ‘Study’ (MBS) that the tobacco companies presented to the Massachusetts Department of Public Health (MDPH) in 1999 in response to ingredient disclosure regulations in the state. This case study can inform future ingredient disclosure regulations, including implementation of Articles 9 and 10 of the WHO Framework Convention on Tobacco Control (FCTC). Methods We analysed documents available at http://legacy.library.ucsf.edu to identify internal communications regarding the design and execution of the MBS and internal studies on the relationship between tar, nicotine and carbon monoxide and smoke constituents and reviewed publications that further evaluated data published as part of the MBS. Results The companies conducted extensive studies of cigarette design factors and ingredients that significantly impacted the levels of constituents. While this study asserted that by-brand emissions could be estimated reliably from published tar, nicotine, and carbon monoxide levels, the tobacco companies were well aware that factors beyond tar, nicotine and carbon monoxide influenced levels of constituents included in the study. This severely limited the potential usefulness of the MBS predictor equations. Conclusions Despite promises to provide data that would allow regulators to predict constituent data for all brands on the market, the final MBS results offered no useful predictive information to inform regulators, the scientific community or consumers. When implementing FCTC Articles 9 and 10, regulatory agencies should demand detailed by-brand information on tobacco product constituents and toxin deliveries to users. PMID:26292701

    Quality improvement collaboratives are a popular model used to address gaps between evidence-based practice and patient care. Little is known about use of such collaboratives in emergency medical services, particularly for improving prehospital stroke care. To determine the feasibility of using this approach to improve prehospital stroke care, we conducted a pilot study of the Emergency Medical Services Stroke Quality Improvement Collaborative. Seventeen Massachusetts emergency medical service agencies participated in the quality improvement collaborative pilot project. We identified 5 prehospital stroke performance measures to assess the quality of prehospital care, guide collaborative activities, and monitor change in performance over time. During learning sessions, participants were trained in quality improvement and performance measurement, analyzed performance measure results, and shared successes and challenges. Focus groups were conducted to understand participants' experiences with the collaborative. Participating emergency medical service agencies collected stroke performance measures on 3,009 stroke patients during the pilot study. Adherence to 4 of 5 performance measures increased significantly over time. Participants acknowledged that the collaborative provided them with an efficient and effective framework for stroke quality improvement and peer-learning opportunities. As evidenced in Massachusetts, quality improvement collaboratives can be an effective tool to improve prehospital stroke care. The data collected, improvements made, participation of emergency medical service agencies, and positive experiences within the collaborative support the continued use of this approach.

  20. Middle school science curriculum design and 8th grade student achievement in Massachusetts public schools

    Science.gov (United States)

    Clifford, Betsey A.

    The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used teaching middle school science: integrated and discipline-based. In the proposed standards, the Massachusetts DESE uses grade-by-grade standards using an integrated approach. It was not known if there is a statistically significant difference in student achievement on the 8th grade science MCAS assessment for students taught with an integrated or discipline-based approach. The results on the 8th grade science MCAS test from six public school districts from 2010 -- 2013 were collected and analyzed. The methodology used was quantitative. Results of an ANOVA showed that there was no statistically significant difference in overall student achievement between the two curriculum models. Furthermore, there was no statistically significant difference for the various domains: Earth and Space Science, Life Science, Physical Science, and Technology/Engineering. This information is useful for districts hesitant to make the change from a discipline-based approach to an integrated approach. More research should be conducted on this topic with a larger sample size to better support the results.

    We evaluated the Massachusetts Fire Safe Cigarette Law's (FSCL's) effectiveness in preventing residential fires. We examined unintentional residential fires reported to the Massachusetts Fire Incident Reporting System from 2004 to 2010. We analyzed FSCL effect on the likelihood of cigarette- versus noncigarette-caused fires and effect modification by fire scenario factors by using an interrupted time series regression model. We analyzed the effect of FSCL on monthly fire rates with Poisson regression. Cigarettes caused 1629 unintentional residential fires during the study period. The FSCL was associated with a 28% (95% confidence interval = 12%, 41%) reduction in the odds of cigarette- versus noncigarette-caused fires, although not in analyses restricted to casualty fires, with smaller sample size. The largest reductions were among fires in which human factors were involved; that were first ignited on furniture, bedding, or soft goods; that occurred in living areas; or that occurred in the summer or winter. The FSCL appears to have decreased the likelihood of cigarette-caused residential fires, particularly in scenarios for which the ignition propensity standard was developed. Current standards should be adopted, and the need for strengthening should be considered.

  2. Storm tide monitoring during the blizzard of January 26-28, 2015, in eastern Massachusetts

    2015-01-01

    The U.S. Geological Survey (USGS) deployed a temporary monitoring network of six storm surge sensors and four barometric pressure sensors along the Atlantic coast in eastern Massachusetts, from Plymouth to Newburyport, before the blizzard of January 26–28, 2015 (Blizzard of January 2015), to record the timing and magnitude of storm tide at select locations where forecasters had predicted the potential for coastal flooding. Additionally, water-level data were recorded and transmitted in near real-time from four permanent USGS tidal stations—three on Cape Cod and one near the mouth of the Merrimack River in Newburyport. The storm surge sensors were deployed at previously established fixed sites outfitted with presurveyed mounting brackets. The mounting brackets were installed in 2014 as part of the USGS Surge, Wave, and Tide Hydrodynamic (SWaTH) Network (https://water.usgs.gov/floods/STN/), which was funded through congressional supplemental appropriations for the U.S. Department of the Interior after the devastating landfall of Hurricane Sandy on October 29, 2012 (Simmons and others, 2014). The USGS received this funding to enable better understanding of coastal flooding hazards in the region, to improve preparedness for future coastal storms, and to increase the resilience of coastal cities, infrastructure, and natural systems in the region (Buxton and others, 2013). The USGS established 163 monitoring locations along the New England coast for the SWaTH Network, including 70 sites in Massachusetts.

    This is the third year of operations for work under the Cooperative Agreement between the Commonwealth of Massachusetts Photovoltaic Center and the U.S. Department of Energy. As a collaborative effort with shared resources, the activity at the Photovoltaic Center and the University of Lowell Photovoltaic Program has continued to advance the utilization and implementation of photovoltaic-powered systems into society. The programs and activities developed over the past three years have supported strategies that cover both international utilization as well as domestic application. Three major areas of activities have centered around the following themes: (1) The identification of market opportunities to enlarge sales potential for the photovoltaic industry. (2) The development of a knowledgeable infrastructure to support PV diffusion in Massachusetts, in the United States, and around the world. (3) The analysis of the physical, economic, and regulatory environment in which PV must compete with mature energy technologies. This past year has been an experience of contrasts for the Photovoltaic Center. Projects and activities have resulted in the successful completion of programs goals.

  4. Evaluation of the home-energy-rating concept and the Massachusetts Pilot Project

    1983-06-01

    This is a report on the results of an evaluation of a home-energy-rating concept based on a Massachusetts pilot project. The focus of the evaluation was on: (1) the compatibility of the Massachusetts rating with the RCS program, (2) who would use the rating and how, (3) qualitative estimates of benefits and costs, and (4) recommendations for further use and testing of the rating. In addition the evaluation of the rating concept also attempted to determine what if any effect the home energy rating has on the demand for energy audits, on the propensity of customers who received ratings to undertake recommended energy-efficiency home improvements, and on changes in mortgage-lending procedures for energy-efficient homes. The evaluation consisted of telephone and in-person discussions with the project developers, the various professional user groups, the recipients of the energy ratings, and control groups of audit customers that did not receive the energy rating. The evaluation was designed to determine the results of the pilot project, assess the project's effectiveness, and analyze the potential for transferring the rating procedure to other geographic locations.

    Reducing the incidence and negative consequences of concussion among youth athletes is a public health priority. In 2010, Massachusetts passed legislation aimed at addressing the issue of concussions in school athletics. We sought to understand local-level implementation decisions of the Massachusetts concussion law. A qualitative multiple-case study approach was utilized. Semi-structured interviews with school-employed actors associated with the law's implementation were used for analysis. Interview data were subjected to a conventional content analysis. A total of 19 participants from 5 schools were interviewed. Schools were purposefully selected from communities varying in socioeconomic status and population. Participants included 5 athletic directors, 5 coaches, 4 athletic trainers, 4 school nurses, and 1 health and wellness coordinator. Eight themes emerged regarding specific ways schools have implemented the law. Six themes emerged regarding factors influencing implementation. All cases employ neurocognitive testing as a means to assess concussions, place decision-making authority in athletic trainers' hands, and use a 30-minute online video to disseminate concussion education. Employing athletic trainers could pose challenges to school districts with limited financial capacity, as financial assistance from the state is not provided under the law. The validity of neurocognitive testing and the effectiveness of online concussion training need further study. Cooperation from student athletes, their parents, and physicians is necessary for full implementation of the law. © 2016 American Society of Law, Medicine & Ethics.

  6. The Massachusetts Sustainable-Yield Estimator: A decision-support tool to assess water availability at ungaged stream locations in Massachusetts

    Federal, State and local water-resource managers require a variety of data and modeling tools to better understand water resources. The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, has developed a statewide, interactive decision-support tool to meet this need. The decision-support tool, referred to as the Massachusetts Sustainable-Yield Estimator (MA SYE) provides screening-level estimates of the sustainable yield of a basin, defined as the difference between the unregulated streamflow and some user-specified quantity of water that must remain in the stream to support such functions as recreational activities or aquatic habitat. The MA SYE tool was designed, in part, because the quantity of surface water available in a basin is a time-varying quantity subject to competing demands for water. To compute sustainable yield, the MA SYE tool estimates a daily time series of unregulated, daily mean streamflow for a 44-year period of record spanning October 1, 1960, through September 30, 2004. Selected streamflow quantiles from an unregulated, daily flow-duration curve are estimated by solving six regression equations that are a function of physical and climate basin characteristics at an ungaged site on a stream of interest. Streamflow is then interpolated between the estimated quantiles to obtain a continuous daily flow-duration curve. A time series of unregulated daily streamflow subsequently is created by transferring the timing of the daily streamflow at a reference streamgage to the ungaged site by equating exceedence probabilities of contemporaneous flow at the two locations. One of 66 reference streamgages is selected by kriging, a geostatistical method, which is used to map the spatial relation among correlations between the time series of the logarithm of daily streamflows at each reference streamgage and the ungaged site. Estimated unregulated, daily mean streamflows show good agreement with observed

  10. Magnitude of flood flows for selected annual exceedance probabilities for streams in Massachusetts

    Science.gov (United States)

    Zarriello, Phillip J.

    2017-05-11

    The U.S. Geological Survey, in cooperation with the Massachusetts Department of Transportation, determined the magnitude of flood flows at selected annual exceedance prob­abilities (AEPs) at streamgages in Massachusetts and from these data developed equations for estimating flood flows at ungaged locations in the State. Flood magnitudes were deter­mined for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent AEPs at 220 streamgages, 125 of which are in Massachusetts and 95 are in the adjacent States of Connecticut, New Hamp­shire, New York, Rhode Island, and Vermont. AEP flood flows were computed for streamgages using the expected moments algorithm weighted with a recently computed regional skew­ness coefficient for New England.Regional regression equations were developed to estimate the magnitude of floods for selected AEP flows at ungaged sites from 199 selected streamgages and for 60 potential explanatory basin characteristics. AEP flows for 21 of the 125 streamgages in Massachusetts were not used in the final regional regression analysis, primarily because of regulation or redundancy. The final regression equations used general­ized least squares methods to account for streamgage record length and correlation. Drainage area, mean basin elevation, and basin storage explained 86 to 93 percent of the variance in flood magnitude from the 50- to 0.2-percent AEPs, respec­tively. The estimates of AEP flows at streamgages can be improved by using a weighted estimate that is based on the magnitude of the flood and associated uncertainty from the at-site analysis and the regional regression equations. Weighting procedures for estimating AEP flows at an ungaged site on a gaged stream also are provided that improve estimates of flood flows at the ungaged site when hydrologic characteristics do not abruptly change.Urbanization expressed as the percentage of imperviousness provided some explanatory power in the regional regression; however, it was not statistically

  11. Bone organic matter and radiocarbon dating

    1967-01-01

    Unsatisfactory results with the carbon-14 dating of bone organic matter have caused bone radiocarbon dates to be considered unreliable. Even the so-called collagen dates are commonly erroneous for samples more than a few thousand years old. Current efforts at the University of Arizona are directed towards understanding why bone yields erroneous results, what is the nature of the contaminants, and what can be done to obtain accurate dates from bone organic matter. Bone from extinct Pleistocene animals from stratified sites with adequate geochronological control was selected for analysis. From each sample four organic fractions (humic acids, fulvic acids, soluble bone organic matter, and insoluble bone organic matter) were chemically separated and analysed for carbon-14. The results were then compared to radiocarbon dates on associated wood or charcoal or age estimates based upon other data. Results suggest that collagen, free of humic acids, yields reliable results and is the only reliable organic fraction for dating fossil bone. Humic acids that are not removed by standard pre-treatment are a prime suspect in the contamination of 'collagen' and can lead to dates that are too old as well as too young. (author)

  12. Dating of fossil hominid: problems and perspectives

    The hominid dating anterior to the Homo Erectus has been based up to now on the rocks and minerals geochronology of vulcanic origem in stratigraphic relation with the fossils. Two methods are widely used, potassium-argon and uranium fission track dating. The vulcanic material dating; lava, lephra, associated with the hominid leavings show big difficults essentially connected to several types of contamination and modification. Two available examples inside the east-african rift show the probelms linked to these dating. The current progresses in the dating methods can contribute by one hand to a better utilization of the K-Ar and fisson track methods for the vulcanic materials. By other hand, with the introduction of new dating methods (thermoluminescence and electron paramagnetic resonance) will be possible to date directly whether the fossil bone itself or the associated sedimentar material. This open new perspectives in particular for every sites which are not inter-stratified with the vulcanic material. (L.C.) [pt

  13. Date palm micropropagation: Advances and applications

    Directory of Open Access Journals (Sweden)

    Jameel Mohammed Al-Khayri

    Full Text Available ABSTRACT Date palm (Phoenix dactylifera L. is a fruit tree resilient to adverse climatic conditions predominating in hot arid regions of the Middle East and North Africa. The date fruit contains numerous chemical components that possess high nutritional and medicinal values. Traditional propagation by offshoots is inefficient to satisfy current demands for date palm trees. Alternatively, micropropagation provides an efficient means for large-scale propagation of date palm cultivars. Both somatic embryogenesis and organogenesis, either directly or indirectly though the callus phase, have been demonstrated in date palm in vitro regeneration. Culture initiation commonly utilizes shoot-tip explants isolated from young offshoots. Recently, the immature inflorescences of adult trees were utilized as an alternative nondestructive source of explants. In addition to the nature of the explant used, successful plant regeneration depends on the cultivar, composition of the culture medium and physical status. Challenges of date palm micropropagation include long in vitro cycle, latent contamination, browning, somaclonal variation as well as ex vitro acclimatization and transplanting. A remarkable amount of research investigating these factors has led to optimized protocols for the micropropagation of numerous commercially important cultivars. This has encouraged the development of several international commercial tissue culture laboratories. Molecular characterization provides an assurance of genetic conformity of regenerated plantlets, a key feature for commercial production. This article describes date palm micropropagation protocols and also discusses recent achievements with respect to somaclonal variation, molecular markers, cryopreservation and future prospects.

  14. Luminescence dating of glaciofluvial deposits: A review

    2009-12-01

    For glacigenic sediments, Optically Stimulated Luminescence (OSL) dating offers an opportunity to date the time of deposition of quartz and feldspar minerals that are ubiquitous within the sediment matrix, rather than relying upon the chance occurrence of organic material for radiocarbon dating. The OSL dating signal or charge accumulates in crystal defects of individual quartz and feldspar minerals through exposure to environmental radiation within their depositional setting. The OSL signal within individual grains can be reset or bleached through exposure to daylight during transportation processes. Thus OSL dating of sediments attempts to determine the time elapsed since burial. Glacigenic sediments present considerable challenges for OSL dating not only in terms of poor bleaching of the OSL signal during the transport and deposition cycle, but also poor quartz luminescence characteristics which are often related to sediment provenance, the nature of the bedrock or source material, and the freshly eroded nature of many such deposits. This paper reviews luminescence dating techniques as applied to glaciofluvial sediments and explores the challenges that such deposits present to the technique. Successful application of OSL techniques can be judged in a number of ways: comparison with the 'independent' chronologies is prevalent in the literature, but recently the movement towards measurement of large numbers of small aliquots and single grains allows a more robust assessment of luminescence properties and behaviour for individual samples and ultimately more precise luminescence ages to be determined. For glaciofluvial sediments in particular, it is important to investigate the depositional sub-environment of each sample in relation to the chance of sufficient bleaching during transport and deposition. A lithofacies-based approach to sampling for optically stimulated luminescence dating of these sediments is suggested whereby hypothetically well-bleached deposits

    Most of Earth's present-day crust formed at mid-ocean ridges. High-precision uranium-lead dating of zircons in gabbros from the Vema Fracture Zone on the Mid-Atlantic Ridge reveals that the crust there grew in a highly regular pattern characterized by shallow melt delivery. Combined with results from previous dating studies, this finding suggests that two distinct modes of crustal accretion occur along slow-spreading ridges. Individual samples record a zircon date range of 90,000 to 235,000 years, which is interpreted to reflect the time scale of zircon crystallization in oceanic plutonic rocks.

    The two-decade long history of thermoluminescene as a pottery dating method is surveyed with particular reference to the various problems that have been encountered in the Oxford Laboratory's research programme. Effects, such as supralinearity and radon emanation, are explained in terms of how they are measured and how their existence influences thermoluminescence (TL) dating accuracy (currently close to plus minus 7% per analysis). Illustrations of Thermoluminescence (TL) applications include a Nok culture terracotta from Nigeria and a Cambodia bronze Buddha figure of the Khmer period, dated ising the ceramic-like casting-core retained within it.

    The intensity of thermoluminescence light emitted by a crystal is a function of radiation dose. The number of defects or of radicals in a crystal or organic substances is also a function of radiation dose. Since such defects or radicals present EPR signals, the EPR intensity is also a function of radiation dose. These facts are basis for radiation dosimetry and can be applied in dating of archaeological potteries or other materials, as well as in dating geological substances such as sediments, caves speleothemes, animal teeth and bones. Recent investigation on sensitized quartz based dosimeters and dating calcite covering ancient wall painting to find early settlers in Brazil will be presented. (Author)

    Adolescent dating violence (ADV) is a prevalent social and health problem associated with a number of adolescent risk behaviors and negative outcomes. The purpose of this study was to identify patterns of dating violence across adolescence. We used cross-case analysis to analyze interviews with 88 young adults (men and women aged 18 to 21) who were involved in violent dating relationships as teens. We identified four patterns of dating violence throughout adolescence. We also identified two patterns for adolescents who had only one violent relationship based on the length of the relationship-contained ADV and prolonged ADV-and two patterns for those who had multiple violent relationships based on the level of violence severity-repetitive ADV and escalating ADV. Knowledge of these four patterns can be used to guide therapeutic interactions with teens and to develop pattern-specific prevention and intervention strategies.

    Introduction Theoretic models suggest that associations between substance use and dating violence perpetration may vary in different social contexts, but few studies have examined this proposition. The current study examined whether social control and violence in the neighborhood, peer, and family contexts moderate the associations between substance use (heavy alcohol use, marijuana, and hard drug use) and adolescent physical dating violence perpetration. Methods Adolescents in the eighth, ninth, and tenth grades completed questionnaires in 2004 and again four more times until 2007 when they were in the tenth, 11th and 12th grades. Multilevel analysis was used to examine interactions between each substance and measures of neighborhood, peer, and family social control and violence as within-person (time-varying) predictors of physical dating violence perpetration across eighth through 12th grade (N=2,455). Analyses were conducted in 2014. Results Physical dating violence perpetration increased at time points when heavy alcohol and hard drug use were elevated; these associations were weaker when neighborhood social control was higher and stronger when family violence was higher. Also, the association between heavy alcohol use and physical dating violence perpetration was weaker when teens had more-prosocial peer networks and stronger when teens’ peers reported more physical dating violence. Conclusions Linkages between substance use and physical dating violence perpetration depend on substance use type and levels of contextual violence and social control. Prevention programs that address substance use–related dating violence should consider the role of social contextual variables that may condition risk by influencing adolescents’ aggression propensity.

    2017-12-01

    OBJECTIVE Several similarities exist between the Massachusetts health care reform law of 2006 and the Affordable Care Act (ACA). The authors' prior neurosurgical research showed a decrease in uninsured surgeries without a significant change in surgical volume after the Massachusetts reform. An analysis of the payer-mix status and the age of spine surgery patients, before and after the policy, should provide insight into the future impact of the ACA on spine surgery in the US. METHODS Using the Massachusetts State Inpatient Database and spine ICD-9-CM procedure codes, the authors obtained demographic information on patients undergoing spine surgery between 2001 and 2012. Payer-mix status was assigned as Medicare, Medicaid, private insurance, uninsured, or other, which included government-funded programs and workers' compensation. A comparison of the payer-mix status and patient age, both before and after the policy, was performed. The New York State data were used as a control. RESULTS The authors analyzed 81,821 spine surgeries performed in Massachusetts and 248,757 in New York. After 2008, there was a decrease in uninsured and private insurance spine surgeries, with a subsequent increase in the Medicare and "other" categories for Massachusetts. Medicaid case numbers did not change. This correlated to an increase in surgeries performed in the age group of patients 65-84 years old, with a decrease in surgeries for those 18-44 years old. New York showed an increase in all insurance categories and all adult age groups. CONCLUSIONS After the Massachusetts reform, spine surgery decreased in private insurance and uninsured categories, with the majority of these surgeries transitioning to Medicare. Moreover, individuals who were younger than 65 years did not show an increase in spine surgeries, despite having greater access to health insurance. In a health care system that requires insurance, the decrease in private insurance is primarily due to an increasing elderly

  19. Flooding and emergency room visits for gastrointestinal illness in Massachusetts: a case-crossover study.

    Full Text Available INTRODUCTION: Floods and other severe weather events are anticipated to increase as a result of global climate change. Floods can lead to outbreaks of gastroenteritis and other infectious diseases due to disruption of sewage and water infrastructure and impacts on sanitation and hygiene. Floods have also been indirectly associated with outbreaks through population displacement and crowding. METHODS: We conducted a case-crossover study to investigate the association between flooding and emergency room visits for gastrointestinal illness (ER-GI in Massachusetts for the years 2003 through 2007. We obtained ER-GI visits from the State of Massachusetts and records of floods from the National Oceanic and Atmospheric Association's Storm Events Database. ER-GI visits were considered exposed if a flood occurred in the town of residence within three hazard periods of the visit: 0-4 days; 5-9 days; and 10-14 days. A time-stratified bi-directional design was used for control selection, matching on day of the week with two weeks lead or lag time from the ER-GI visit. Fixed effect logistic regression models were used to estimate the risk of ER-GI visits following the flood. RESULTS AND CONCLUSIONS: A total of 270,457 ER-GI visits and 129 floods occurred in Massachusetts over the study period. Across all counties, flooding was associated with an increased risk for ER-GI in the 0-4 day period after flooding (Odds Ratio: 1.08; 95% Confidence Interval: 1.03-1.12; but not the 5-9 days (Odds Ratio: 0.995; 95% Confidence Interval: 0.955-1.04 or the 10-14 days after (Odds Ratio: 0.966, 95% Confidence Interval: 0.927-1.01. Similar results were observed for different definitions of ER-GI. The effect differed across counties, suggesting local differences in the risk and impact of flooding. Statewide, across the study period, an estimated 7% of ER-GI visits in the 0-4 days after a flood event were attributable to flooding.

    There is a substantial concern among spine surgeons that healthcare reform efforts will alter the processes through which spinal care is delivered and decrease overall quality. We used the Statewide Inpatient Dataset for Massachusetts to evaluate changes in hospital processes and quality of care for patients with cervical fractures following the implementation of health reform. This was a pre-post retrospective analysis of patients (n=9,387) treated for cervical fractures in Massachusetts between 2003-2006 and 2008-2010. Changes in hospital processes (surgical intervention, length of stay (LOS) and environment of care) and quality of care (mortality, complications, reoperation and failure to rescue (FTR)) were the outcomes of interest. FTR is a quality measure that evaluates a hospital's capacity to avoid mortality following the occurrence of a sentinel complication. Patients treated between 2003 and 2006 were considered the pre-reform group. The post-reform cohort consisted of those treated from 2008 to 2010. Baseline differences between cohorts were evaluated using chi-square or Mann-Whitney U tests. Unadjusted comparisons between the dependent variables and the onset of healthcare reform were performed, followed by regression techniques that adjusted for differences in case-mix and whether a surgical intervention was performed. Multivariable logistic regression was used for categorical variables and negative binomial regression was employed for continuous variables. The rates of surgical intervention remained unchanged pre- and post-reform (p=0.25). Hospital length of stay (RC: -0.18, 95% CI: -0.22, -0.14) and the FTR rate following surveillance insensitive complications (OR: 0.49, 95% CI: 0.25, 0.94) were significantly reduced following health reform. Post-reform, academic centers experienced a 22% reduction in mortality (95% CI: 0.61, 0.99) a 40% decrease in FTR (95% CI: 0.40, 0.89), a 30% decrease in surveillance insensitive complications (95% CI: 0.51, 0

  1. Linking student performance in Massachusetts elementary schools with the "greenness" of school surroundings using remote sensing.

    Full Text Available Various studies have reported the physical and mental health benefits from exposure to "green" neighborhoods, such as proximity to neighborhoods with trees and vegetation. However, no studies have explicitly assessed the association between exposure to "green" surroundings and cognitive function in terms of student academic performance. This study investigated the association between the "greenness" of the area surrounding a Massachusetts public elementary school and the academic achievement of the school's student body based on standardized tests with an ecological setting. Researchers used the composite school-based performance scores generated by the Massachusetts Comprehensive Assessment System (MCAS to measure the percentage of 3rd-grade students (the first year of standardized testing for 8-9 years-old children in public school, who scored "Above Proficient" (AP in English and Mathematics tests (Note: Individual student scores are not publically available. The MCAS results are comparable year to year thanks to an equating process. Researchers included test results from 2006 through 2012 in 905 public schools and adjusted for differences between schools in the final analysis according to race, gender, English as a second language (proxy for ethnicity and language facility, parent income, student-teacher ratio, and school attendance. Surrounding greenness of each school was measured using satellite images converted into the Normalized Difference Vegetation Index (NDVI in March, July and October of each year according to a 250-meter, 500-meter, 1,000-meter, and 2000-meter circular buffer around each school. Spatial Generalized Linear Mixed Models (GLMMs estimated the impacts of surrounding greenness on school-based performance. Overall the study results supported a relationship between the "greenness" of the school area and the school-wide academic performance. Interestingly, the results showed a consistently positive significant association

  2. Dating ancient monuments by nuclear radiation

    In the fifties and sixties several disciplines dealing with chronologies but lacking precise methods of measurements (geology, biology, archaeology and art history) became aware of the radioactive decay as a tool of measuring elapsed time. Among the disciplines that benefit most from physical methods archaeology has to be named first. So was archaeological work revolutionised by the introduction of the C-14 dating method. A wider selection of material became datable after the introduction of luminescence techniques using the effect of nuclear radiation on semiconductors. These minerals are widespread among archaeological materials. In ancient monuments, the objective of this paper, semiconductors almost exclusively form the material basis. Over the last four millennia wood, stone, mortar and fired bricks have been used for the construction of buildings. After discussing methods taking wood as a dating material, a broader view will be given on the results achieved by luminescence dating of fired bricks, mortar and stone. For many years brick dating was performed by thermoluminescence, the recipes followed those of ceramic dating. Preferably multiple aliquot additive dose protocols were used on polymineral fine grain fractions (1-10 μm). It was expected that the error in dating monuments would be smaller compared to ceramic dating, because of the constancy of the environmental conditions which a brick experiences during its lifetime. However, the variability of firing temperatures in brick kilns overthrows this advantage. Therefore, the demands of art historians to fall short of an error margin of 5% could generally not be fulfilled. Especially in medieval or renaissance times the temporal resolution of thermoluminescence is inferior to traditional stylistic dating as long as specific stylistic forms are present. New optical luminescence techniques and a new philosophy of dose evaluation, based on single aliquot regeneration protocols, produce less scatter, and in

    Background Patients with venous thromboembolism (VTE) require access to comprehensive physician and pharmacy benefits to prevent recurrence and hemorrhage. Prior to 2006, Massachusetts provided these benefits through a program restricted to safety net hospitals called Free Care. Providing portable health insurance through Massachusetts health reform could improve outcomes for uninsured with VTE but its cost-effectiveness is unknown. Methods and Results We constructed a Markov decision analysis model comparing our conceptualization of the Massachusetts health reform (“health reform strategy”) to no health reform strategy for a patient beginning warfarin for new episode of VTE. In the model, a patient may develop recurrent VTE or develop hemorrhage or stop warfarin after 6 months if no event occurs. To measure effectiveness, we analyzed laboratory data from Boston Medical Center, the largest safety net hospital in Massachusetts. Specifically, we measured the probability of having a subtherapeutic warfarin level for patients newly insured compared to those on Free Care pre-reform adjusting for secular trends. To calculate inpatient costs, we used the Health Care Utilization Project (HCUP). We then calculated the incremental cost effectiveness ratio (ICER) for the health reform strategy adjusted to 2014 USD per quality adjusted life year (QALY) and performed sensitivity analyses. The health reform strategy cost less and gained more QALYS than the no health reform strategy. Our result was most sensitive to the odds that Health Reform protected against a subtherapeutic warfarin level, the cost of Health Reform, and the percentage of total health care costs attributable to VTE in Massachusetts. Conclusions The health reform strategy cost less and was more effective than the no health reform strategy for patients with VTE. PMID:26908086

    The relationship between reported bullying, reported dating violence, and dating relationship quality measured through couple observations was examined. Given past research demonstrating similarity between peer and dating contexts, we expected that bullying would predict negative dating experiences. Participants with dating experience (n = 585; 238 males, M(age) = 15.06) completed self-report assessments of bullying and dating violence perpetration and victimization. One month later, 44 opposite-sex dyads (M(age) = 15.19) participated in behavioral observations. In 10-min sessions, couples were asked to rank and discuss areas of relationship conflict while being video-recorded. Qualities of the relationship were later coded by trained observers. Regression analysis revealed that bullying positively predicted dating violence perpetration and victimization. Self-reported bullying also predicted observations of lower relationship support and higher withdrawal. Age and gender interactions further qualified these findings. The bullying of boys, but not girls, was significantly related to dating violence perpetration. Age interactions showed that bullying was positively predictive of dating violence perpetration and victimization for older, but not younger adolescents. Positive affect was also negatively predicted by bullying, but only for girls. These findings add to the growing body of evidence that adolescents carry forward strategies learned in the peer context to their dating relationships. © The Author(s) 2014.

    We develop and implement what we believe is the first conceptually valid health-inclusive poverty measure (HIPM) - a measure that includes health care or insurance in the poverty needs threshold and health insurance benefits in family resources - and we discuss its limitations. Building on the Census Bureau's Supplemental Poverty Measure, we construct a pilot HIPM for the under-65 population under ACA-like health reform in Massachusetts. This pilot demonstrates the practicality, face validity and value of a HIPM. Results suggest that public health insurance benefits and premium subsidies accounted for a substantial, one-third reduction in the health inclusive poverty rate. Copyright © 2016 Elsevier B.V.

    Cetacean (whales, dolphins and porpoises) mass strandings are a longstanding mystery in the field of marine biology that continue to be recorded in coastal environments around the world. For each of these events, anywhere from a few to several hundred otherwise healthy animals strand in onshore environments, often for no apparent reason. While the causes of these events remain unclear, anthropogenic and naturogenic mechanisms have been suggested. We present results of an inter-disciplinary study that draws expertise from space weather, marine mammal biology and ecology, and marine mammal stranding response. This study assessed 16 years of cetacean stranding events in the Cape Cod (Massachusetts, USA) area concurrently with a large dataset of meteorological, geophysical, biological, oceanographic and space weather data to produce inferences about possible causes for these unexplained events.

    In almost all states in the United States, to carry a concealed handgun legally requires a permit from the police. Many states have changed from may-issue laws (where the local police chief has discretion about to whom to issue a license) to shall-issue laws (where the police chief must issue a permit if the applicant passes a computerized federal background check). Studies conflict on the effect on crime. None considered the situation in may-issue states when police used discretion and refused to issue a permit. We provide suggestive evidence from a December 2013 survey of police chiefs in Massachusetts' 351 cities and towns. Of the 121 responding police chiefs, a large majority favored retaining police discretion. Chiefs issued few discretionary denials - median 2 per year, citing providing false information, a history of assault (often domestic violence), a history of drug or alcohol abuse, or of mental-health issues as the most common reasons for denial.

    2018-01-01

    We examine the impact of the 2006 Massachusetts healthcare reform on substance use disorder (SUD) treatment facilities' provision of care. We test the impact of the reform on treatment quantity and access. We couple data on the near universe of specialty SUD treatment providers in the USA with a synthetic control method approach. We find little evidence that the reform lead to changes in treatment quantity or access. Reform effects were similar among for-profit and non-profit facilities. In an extension, we show that the reform altered the setting in which treatment is received, the number of offered services, and the number of programs for special populations. These findings may be useful in predicting the implications of major health insurance expansions on the provision of SUD treatment. Copyright © 2017 John Wiley & Sons, Ltd.

    Amersham Corporation, Burlington, Massachusetts, a licensee of the US Nuclear Regulatory Commission (NRC), authorized to manufacture and distribute iridium-192 and cobalt-60 source assemblies for use in radiography equipment, received a shipment of 14 source changer son March 8, 1990, that were being returned from their product distributor, NDI Corporation in Seoul, Korea. One source changer contained a small sealed source in an unshielded location. Amersham employees retrieved the source, secured it in a hot cell, and notified NRC's Region I. Subsequently, NRC dispatched an Incident Investigation Team to perform a comprehensive review of this incident and determine the potential for exposure to those who handled the source changer and to members of the general public. This report describes the incident and the methodology used in the investigation and presents the Team's findings and conclusions

    The objective of this study was to compare the prevalence of home care practices in very to moderately preterm (VPT), late preterm (LPT) and term infants born in Massachusetts. Using 2007 to 2010 Massachusetts Pregnancy Risk Assessment Monitoring System data, births were categorized by gestational age (VPT: 23 to 33 weeks; LPT: 34 to 36 weeks; term: 37 to 42 weeks). Home care practices included breastfeeding initiation and continuation, and infant sleep practices (supine sleep position, sleeping in a crib, cosleeping in an adult bed). We developed multivariate models to examine the association of infant sleep practices and breastfeeding with preterm status, controlling for maternal sociodemographic characteristics. Supine sleep position was more prevalent among term infants compared with VPT and LPT infants (77.1%, 71.5%, 64.4%; P=0.02). In the adjusted model, LPT infants were less likely to be placed in supine sleep position compared with term infants (adjusted prevalence ratio=0.86; 95% confidence interval: 0.75 to 0.97). Breastfeeding initiation and continuation did not differ among preterm and term groups. Nearly 16% of VPT and 18% of LPT and term infants were not sleeping in cribs and 14% of LPT and term infants were cosleeping on an adult bed. Compared with term infants, LPT infants were less likely to be placed in supine sleep position after hospital discharge. A significant percent of preterm and term infants were cosleeping on an adult bed. Hospitals may consider improving their safe sleep education, particularly to mothers of LPT infants.

    This report presents high-resolution maps of the seafloor offshore of Massachusetts, from Nahant to Gloucester. Approximately 134 km² of the inner shelf were mapped with a focus on the nearshore region in water depths less than 40 m (fig. 1.1). The maps were prepared as part of a cooperative mapping program between the U.S. Geological Survey (USGS) and the Massachusetts Office of Coastal Zone Management (CZM). They are based on marine geophysical data, sediment sampling, and bottom photography obtained on two research cruises carried out in 2003 and 2004. The primary objective of this program is to develop a suite of seafloor maps that provide geologic information for management of coastal and marine resources. Accurate maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine reserves, and assessing environmental changes due to natural or human impacts. The maps also provide a geologic framework for scientific research, industry and the public. The organization of this report is outlined in the navigation bar along the left-hand margin of the page. This is section 1, the introduction. Section 2 briefly describes the mapping products contained in this report and has links to large-format map sheets, that can be viewed on line or downloaded. Section 3 is a description of the data collection, processing, and analysis procedures used to create the map products. Section 4 examines the geologic framework and late Quaternary evolution of the region, and presents two different strategies for mapping the complex seafloor. This report also contains four appendices that include GIS layers of all data collected in this study, and copies of the sample and photographic data used to validate the interpretations.

    Highlights: • This study examines the relationship between recycling rate of solid waste and air pollution. • Fixed effects Stochastic Frontier Analysis model with panel data are employed. • The case study is a waste municipality survey in the state of Massachusetts during 2009–2012. • The findings support that a negative relationship between air pollution and recycling. - Abstract: This study examines the relationship between recycling rate of solid waste and air pollution using data from a waste municipality survey in the state of Massachusetts during the period 2009–2012. Two econometric approaches are applied. The first approach is a fixed effects model, while the second is a Stochastic Frontier Analysis (SFA) with fixed effects model. The advantage of the first approach is the ability of controlling for stable time invariant characteristics of the municipalities, thereby eliminating potentially large sources of bias. The second approach is applied in order to estimate the technical efficiency and rank of each municipality accordingly. The regressions control for various demographic, economic and recycling services, such as income per capita, population density, unemployment, trash services, Pay-as-you-throw (PAYT) program and meteorological data. The findings support that a negative relationship between particulate particles in the air 2.5 μm or less in size (PM{sub 2.5}) and recycling rate is presented. In addition, the pollution is increased with increases on income per capita up to $23,000–$26,000, while after this point income contributes positively on air quality. Finally, based on the efficiency derived by the Stochastic Frontier Analysis (SFA) model, the municipalities which provide both drop off and curbside services for trash, food and yard waste and the PAYT program present better performance regarding the air quality.

    Full Text Available Less than one third of American eighth graders score in the two highest performance levels on the grade 8 mathematics test given by the National Assessment of Educational Progress. Only a little over one third of Massachusetts eighth graders score at the two highest performance levels on the state’s own grade 8 mathematics test. In 2002, the Massachusetts Department of Education funded research to explore why there had been no significant growth in the percent of grade 8 students performing at the two highest levels on the state’s grade 8 mathematics tests. An analysis of quantitative data obtained from administrators and teachers in a representative sample of 60 schools throughout the state in 2003 identified school-based factors that were significantly associated with the 20 of the 60 schools that both increased above the state average increase the percent of grade 8 students performing at the two highest performance levels on the state’s grade 8 mathematics test and simultaneously decreased above the state average decrease the percent of grade 8 students performing at the lowest performance level. A significantly higher percent of teachers in these 20 schools reported spending a great deal of time reviewing and using test results, having a voice in the choice of their instructional materials, using accelerated and leveled algebra I classes to address the needs of above grade students, and less frequent use of calculators in non-algebra classes. At a time when teachers in all states are being held accountable for increasing the achievement of all their students, these findings warrant exploration on a nationwide scale.

    Massachusetts and Cape Cod Bays form a semienclosed coastal basin that opens onto the much larger Gulf of Maine. Subtidal circulation in the bay is driven by local winds and remotely driven flows from the gulf. The local-wind forced flow is estimated with a regional shallow water model driven by wind measurements. The model uses a gravity wave radiation condition along the open-ocean boundary. Results compare reasonably well with observed currents near the coast. In some offshore regions however, modeled flows are an order of magnitude less energetic than the data. Strong flows are observed even during periods of weak local wind forcing. Poor model-data comparisons are attributable, at least in part, to open-ocean boundary conditions that neglect the effects of remote forcing. Velocity measurements from within Massachusetts Bay are used to estimate the remotely forced component of the flow. The data are combined with shallow water dynamics in an inverse-model formulation that follows the theory of Bennett and McIntosh [1982], who considered tides. We extend their analysis to consider the subtidal response to transient forcing. The inverse model adjusts the a priori open-ocean boundary condition, thereby minimizing a combined measure of model-data misfit and boundary condition adjustment. A "consistency criterion" determines the optimal trade-off between the two. The criterion is based on a measure of plausibility for the inverse solution. The "consistent" inverse solution reproduces 56% of the average squared variation in the data. The local-wind-driven flow alone accounts for half of the model skill. The other half is attributable to remotely forced flows from the Gulf of Maine. The unexplained 44% comes from measurement errors and model errors that are not accounted for in the analysis.

    A current crisis in education is leaving students less prepared to succeed in the working world than any generation before them. Increasingly complex external, nonacademic pressures have an impact on many of today's students, often causing them to drop out of school. Only 76 percent of Massachusetts high school students graduate, and only 29 percent earn a college degree. National figures are worse. Most educational institutions share a common goal to support students in becoming skilled, productive, successful members of society, but the author argues that this goal is not being met. Despite the constant changes in the world, educational practices have remained static. Most public schools are not adapting to meet the shifting needs of students. Universities are not able to prepare the right mix of prospective employees for the demands of the job market; for example, schools are graduating only 10 percent of the needed engineers. Institutions of higher learning cannot keep up with employers' needs in an evolving global market: strong math, science, and writing abilities; critical thinking skills; and the ability to work in teams. The author draws on exemplary efforts at work in his home state of Massachusetts--whose improvements in student achievement outcomes have been some of the best in the nation--to suggest there is promise in twenty-first century learning. Middle school students involved in a NASA-funded project write proposals, work in teams, and engage in peer review. Older students participate in enhanced, hands-on cooperative school-to-work and after-school programs. Schools are starting to offer expanded day learning, increasing the number of hours they are engaged in formal learning. Yet such programs have not reached significant levels of scale. The author calls for a major shift in education to help today's students be successful in the twenty-first century.

    Electronic cash (e-cash) is definitely one of the most popular research topics in the e-commerce field. It is very important that e-cash be able to hold the anonymity and accuracy in order to preserve the privacy and rights of customers. There are two types of e-cash in general, which are online e-cash and offline e-cash. Both systems have their own pros and cons and they can be used to construct various applications. In this paper, we pioneer to propose a provably secure and efficient offline e-cash scheme with date attachability based on the blind signature technique, where expiration date and deposit date can be embedded in an e-cash simultaneously. With the help of expiration date, the bank can manage the huge database much more easily against unlimited growth, and the deposit date cannot be forged so that users are able to calculate the amount of interests they can receive in the future correctly. Furthermore, we offer security analysis and formal proofs for all essential properties of offline e-cash, which are anonymity control, unforgeability, conditional-traceability, and no-swindling.

    The number eight is considered lucky in Chinese culture, e.g. the Beijing Olympics began at 8:08 pm on 8/8/2008. Given the potential for discretion in selecting particular dates of labor induction or scheduled Cesarean section (C-section), we consider whether Chinese-American births in California occur disproportionately on the 8th, 18th, or 28th day of the month. We find 2.3% "too many" Chinese births on these auspicious birth dates, whereas Whites show no corresponding increase. The increase in Chinese births is driven by higher parity C-sections: the number of repeat C-sections is 6% "too high" on auspicious birth dates. Sons born to Chinese parents account for the entire increase; daughter deliveries do not seem to be timed to achieve "lucky" birth dates. We also find avoidance of repeat C-section deliveries on the 4th, 14th, and 24th of the month, considered unlucky in Chinese culture. Finally, we replicate earlier work finding that Friday the 13th delivery dates are avoided and document a particularly large decrease among Chinese. For Whites and Chinese in California, mothers with higher levels of education are particularly likely to avoid delivering on the 13th. Copyright © 2015 Elsevier B.V. All rights reserved.

  20. Dating phylogenies with sequentially sampled tips.

    2013-09-01

    We develop a Bayesian Markov chain Monte Carlo (MCMC) algorithm for estimating divergence times using sequentially sampled molecular sequences. This type of data is commonly collected during viral epidemics and is sometimes available from different species in ancient DNA studies. We derive the distribution of ages of nodes in the tree under a birth-death-sequential-sampling (BDSS) model and use it as the prior for divergence times in the dating analysis. We implement the prior in the MCMCtree program in the PAML package for divergence dating. The BDSS prior is very flexible and, with different parameters, can generate trees of very different shapes, suitable for examining the sensitivity of posterior time estimates. We apply the method to a data set of SIV/HIV-2 genes in comparison with a likelihood-based dating method, and to a data set of influenza H1 genes from different hosts in comparison with the Bayesian program BEAST. We examined the impact of tree topology on time estimates and suggest that multifurcating consensus trees should be avoided in dating analysis. We found posterior time estimates for old nodes to be sensitive to the priors on times and rates and suggest that previous Bayesian dating studies may have produced overconfident estimates.

  1. ESR dating of the fault rocks

    2005-01-01

    We carried out ESR dating of fault rocks collected near the nuclear reactor. The Upcheon fault zone is exposed close to the Ulzin nuclear reactor. The space-time pattern of fault activity on the Upcheon fault deduced from ESR dating of fault gouge can be summarised as follows : this fault zone was reactivated between fault breccia derived from Cretaceous sandstone and tertiary volcanic sedimentary rocks about 2 Ma, 1.5 Ma and 1 Ma ago. After those movements, the Upcheon fault was reactivated between Cretaceous sandstone and fault breccia zone about 800 ka ago. This fault zone was reactivated again between fault breccia derived form Cretaceous sandstone and Tertiary volcanic sedimentary rocks about 650 ka and after 125 ka ago. These data suggest that the long-term(200-500 k.y.) cyclic fault activity of the Upcheon fault zone continued into the Pleistocene. In the Ulzin area, ESR dates from the NW and EW trend faults range from 800 ka to 600 ka NE and EW trend faults were reactivated about between 200 ka and 300 ka ago. On the other hand, ESR date of the NS trend fault is about 400 ka and 50 ka. Results of this research suggest the fault activity near the Ulzin nuclear reactor fault activity continued into the Pleistocene. One ESR date near the Youngkwang nuclear reactor is 200 ka

  2. Equations for estimating bankfull channel geometry and discharge for streams in Massachusetts

    2013-01-01

    Regression equations were developed for estimating bankfull geometry—width, mean depth, cross-sectional area—and discharge for streams in Massachusetts. The equations provide water-resource and conservation managers with methods for estimating bankfull characteristics at specific stream sites in Massachusetts. This information can be used for the adminstration of the Commonwealth of Massachusetts Rivers Protection Act of 1996, which establishes a protected riverfront area extending from the mean annual high-water line corresponding to the elevation of bankfull discharge along each side of a perennial stream. Additionally, information on bankfull channel geometry and discharge are important to Federal, State, and local government agencies and private organizations involved in stream assessment and restoration projects. Regression equations are based on data from stream surveys at 33 sites (32 streamgages and 1 crest-stage gage operated by the U.S. Geological Survey) in and near Massachusetts. Drainage areas of the 33 sites ranged from 0.60 to 329 square miles (mi2). At 27 of the 33 sites, field data were collected and analyses were done to determine bankfull channel geometry and discharge as part of the present study. For 6 of the 33 sites, data on bankfull channel geometry and discharge were compiled from other studies done by the U.S. Geological Survey, Natural Resources Conservation Service of the U.S. Department of Agriculture, and the Vermont Department of Environmental Conservation. Similar techniques were used for field data collection and analysis for bankfull channel geometry and discharge at all 33 sites. Recurrence intervals of the bankfull discharge, which represent the frequency with which a stream fills its channel, averaged 1.53 years (median value 1.34 years) at the 33 sites. Simple regression equations were developed for bankfull width, mean depth, cross-sectional area, and discharge using drainage area, which is the most significant explanatory

    2015-09-01

    An important piece of metadata for any astronomical image is the date and time at which it was observed (and the exposure time). Unfortunately, the values of the observation epoch found in the FITS headers of digitized photographic plates, for example, are not always accurate. There can be many different sources of error: mistakes in the original observation log, errors when converting between different dates and time format (calendar date, Julian days, decimal years, etc.). We present in this paper an analysis of the different values that can be found for the observation epoch of several image sets in various metadata sources. We show how the presence of known asteroids in the field of view can be used to recover the correct time values with a good accuracy.

  5. Radiocarbon dating with accelerator mass spectrometry

    1985-01-01

    Radiocarbon dating by means of accelerator mass spectrometry (AMS) has two great advantages over conventional dating: 1) much smaller samples can be handled and 2) counting time is significantly shorter. Three examples are given for Holocene-age material from east-central Ellesmere Island. The results demonstrate the potential use of this technique as a powerful research tool in studies of Quaternary chronology. Individual fragments of marine shells as small as 0.1 g have been dated successfully at the IsoTrace Laboratory, University of Toronto. In the case of an aquatic moss from a lake sediment core, an increment 0.5 cm thick could be used instead of a 5 cm-thick slice, thus allowing a much more precise estimate of the onset of organic sedimentation

    Irradiation dis infestations of Siwa date fruits seems to be a very promising method. Considerations of the health safety of irradiated date fruits involve nutritional contents has been investigated by chemical analysis. The dose of 400 and 1000 Gy were lethal for the different stages of oases date moth, Ephestia calidella. Dates are a good source of iron and potassium, they also contain calcium, magnesium, copper and other minerals. The radiation dose 1000 Gy had mostly affected the carbohydrates content, some minerals as Fe, Ca and Na partially changed by the treatment. Protein and vitamin contents were slightly affected

    1997-01-01

    The age determination of ancient porcelain using the pre-dose technique in TL dating was reported. The variation of beta dose with depth below the surface of the porcelain slice, the thermal activation characteristic (TAC) for 110 degree C peak, the measurement of paleodose and the estimation of annual dose were studied. The results show that this technique is suitable for authenticity testing of ancient porcelain, but both accuracy and precision for porcelain dating are worse than those for pottery, because porcelain differs from pottery on composition, structure and firing temperature. Besides, some complicated factors in the pre-dose technique would be the possible cause of the greater errors

    The famous catacombs of ancient Rome are huge underground cemeteries, of which two Jewish catacomb complexes of uncertain age and 60 early-Christian catacombs have survived. Here we use radiocarbon dating to determine the age of wood originating from one of the Jewish catacombs and find that it pre-dates its Christian counterparts by at least 100 years. These results indicate that burial in Roman catacombs may not have begun as a strictly Christian practice, as is commonly believed, but rather that its origin may lie in Jewish funerary customs.

    1981-01-01

    A series of replicate experiments, involving analysis of homogenized wood and identical tree-ring sections, suggests that the 14 C counting error in radiocarbon dating quantifies only part of the total variability of measurement. Statistical modelling implies that a more realistic assessment of error is provided by a value approximately three times the counting error. The incorporation of this more realistic measure of variability into an appropriate procedure for calibrating a single date and for matching a floating chronology to a master chronology is described.

    case studies will show the degree of variability of the freshwater reservoir effect over short and long timescales. Radiocarbon dating of recent water samples, aquatic plants and animals, shows that age differences of up to 2000 years can occur within one river. In the Limfjord, freshwater influence...... caused reservoir ages to vary between 250 and 700 years during the period 5400 BC - AD 700. Finally, I will discuss the implications of the freshwater reservoir effect for radiocarbon dating of Mesolithic pottery from inland sites of the Ertebølle culture in Northern Germany....

    The study of radiation defects created in biomaterials, such as bone and teeth, can be used in dating with importance to palaeontology and archaeology. Two Stegomastodon teeth (AL1 and AL2) from north-eastern Brazilian megafauna were studied by electron spin resonance (ESR) spectroscopy. The samples were collected in Fazenda Ovo da Ema, (913349 / 3714965) UTM, Alagoas state, Brazil. The dating of these samples can contribute to the better knowledge of megafauna presence in this region as well as to the events associated to the extinction of these species.

    2018-01-01

    The primary aims of this study were to test whether perceived dating success would differ between offline and online zero-acquaintance dating contexts and to investigate the role that self-esteem might play in these evaluations. Participants were presented with the same photos of targets in either an offline or online dating scenario and rated their chances of dating success along with their perceptions of how attractive they thought the target would consider them. Higher self-esteem individuals believed they would be rated as more attractive. There was an overall perception that, irrespective of self-esteem level, meeting online would lead to better chances of dating success. These findings are considered in relation to an increased ability to more precisely manage impressions and develop an image of the self which would be evaluated more positively online.

  10. Internet dating as a project: the commodification and rationalisation of online dating

    Directory of Open Access Journals (Sweden)

    Tjaša Žakelj

    2015-04-01

    Full Text Available Based on qualitative empirical data from two studies on Internet dating in Slovenia, this paper discusses the social contexts of the Internet dating of heterosexual men and women and homosexual men. Special attention is given to different aspects of the commodification and rationalisation of dating in the process of forming potential (romantic partnerships. First, we discuss our respondents’ reasons for using the Internet to get in touch with potential (romantic partners. Second, we focus on the demands and strategies of targeted market- ing in personal profile writing and, finally, on the process of selecting potential partners. Our study shows that the primary understanding of Internet dating among people who engage in it is its economic nature. Together with targeted marketing and the predeter- mined criteria for choosing interesting others, Internet dating can thus be understood as a market that encourages rationalisation and commodification in the process of forming intimate relationships.

    2017-01-01

    Chronic absenteeism is associated with poorer academic performance and higher attrition in kindergarten to 12th grade (K-12) schools. In prior research, students who were chronically absent generally had fewer employment opportunities and worse health after graduation. We examined the impact that environmental factors surrounding schools have on chronic absenteeism. We estimated the greenness (Normalized Difference Vegetation Index (NDVI)) and fine particulate matter air pollution (PM2.5) within 250 m and 1000 m respectively of each public school in Massachusetts during the 2012–2013 academic year using satellite-based data. We modeled chronic absenteeism rates in the same year as a function of PM2.5 and NDVI, controlling for race and household income. Among the 1772 public schools in Massachusetts, a 0.15 increase in NDVI during the academic year was associated with a 2.6% (p value schools. PMID:28230752

    Shindul-Rothschild, Judith; Gregas, Matt

    2013-01-01

    The Affordable Care Act is modeled after Massachusetts insurance reforms enacted in 2006. A linear mixed effect model examined trends in patient turnover and nurse employment in Massachusetts, New York, and California nonfederal hospitals from 2000 to 2011. The linear mixed effect analysis found that the rate of increase in hospital admissions was significantly higher in Massachusetts hospitals (p<.001) than that in California and New York (p=.007). The rate of change in registered nurses full-time equivalent hours per patient day was significantly less (p=.02) in Massachusetts than that in California and was not different from zero. The rate of change in admissions to registered nurses full-time equivalent hours per patient day was significantly greater in Massachusetts than California (p=.001) and New York (p<.01). Nurse staffing remained flat in Massachusetts, despite a significant increase in hospital admissions. The implications of the findings for nurse employment and hospital utilization following the implementation of national health insurance reform are discussed.

    Few population-based surveys in the United States include sexual orientation as a demographic variable. As a result, estimating the proportion of the U.S. population that is gay, lesbian, or bisexual (GLB) is a substantial challenge. Prior estimates vary widely, from 1-21%. In 2001, questions on sexual orientation and sexual behavior were added to the Massachusetts Behavioral Risk Factor Surveillance System (MA BRFSS) and have been asked continually since that time. The purpose of this study was to determine the prevalence of adults in Massachusetts identifying as GLB and providing a demographic description of this group. The study also examined the correlation of reported sexual behavior and sexual identity within this group. Overall, 1.9% of Massachusetts adults identified as gay or lesbian and 1.0% of Massachusetts adults identified as bisexual. Of those identifying as gay or lesbian, 95.4% reported sexual behavior concordant with this identification, and 99.4% of respondents identifying as heterosexual reported behavior concordant with heterosexual sexual orientation. Among those reporting a GLB sexual orientation, men were more likely than women to identify as gay, and women were more likely than men to identify as bisexual. Younger adults (18-25 years old) were more likely than people in other age groups to identify as bisexual. Respondents with 4 or more years of education were more likely to identify as gay or lesbian than those in all other education categories. The addition of sexual orientation to population-based surveys will allow for research on the health of GLB adults and provide critical information for those charged with the creation of public policy regarding sexual orientation.

    During the MED/AEC era, work involving radioactive materials was conducted at various sites within the arsenal complex. Building 34 housed a uranium machine shop, and a portion of Building 41 contained a foundry that was used for uranium work. Information provided by site personnel indicated that only depleted uranium was used in these buildings. Results of radiological analyses of contaminated material found at these sites indicated depleted uranium with uranium-236. Both buildings have been razed. The remnants still in place consist of the concrete floor slabs, access drives, and underground utility service trenches. This area is currently under the control of the Watertown Redevelopment Authority of Watertown, Massachusetts. During the period from June 25 through July 1, 1981, the Argonne National Laboratory (ANL), Occupational Health and Safety Division (OHS) Radiological Survey Group (RSG), conducted a radiological survey of Building Sites 34 and 41 at the direction of the US Department of Energy. Significant levels of contamination were found at 33 locations on the pad of Site 34 and in 5 out of 15 soild corings from the perimeter of the pad. No contamination was found on the pad of Site 41; however, two-thirds of this pad was covered with soil up to 4 ft thick. One of the 14 soil corings taken adjacent to the pad of Site 41 had elevated levels of uranium. Levels of contamination in excess of criteria, as identified in ANSI 13.12 and NRC Guidelines, were found at this site. The analyses of the samples from the sewer access points also revealed uranium and radium-226 anomalies. Therefore, according to NRC guidelines dated July 1982, it must be concluded that they are contaminated

    This report presents results of a study conducted by the U.S. Geological Survey (USGS), in cooperation with the Massachusetts Department of Environmental Protection, to determine the occurrence of 14 commonly used human-health pharmaceutical compounds and fecal-indicator bacteria in Merrimack River water used as a drinking-water source by 135,000 residents in eastern Massachusetts. The study was designed to complement the USGS National Water-Quality Assessment Program's Source Water-Quality Assessment, which identifies patterns of occurrence of 280 primarily unregulated organic wastewater contaminants in source water used by community water systems and determines whether these patterns also occur in treated drinking water prior to distribution. The study involved periodic collection and analysis of raw Merrimack River water and treated drinking water over the course of 1 year. Water samples were collected periodically without regard to flow regime or antecedent weather conditions at the Lowell Regional Water Utility's Merrimack River intake upstream from Lowell, Mass. The same parcel of water was then sampled as finished water following treatment. Despite the presence of many potential sources of contamination in the drinking-water source area, only 2 of the 14 pharmaceutical analytes were detected at reportable concentrations in the source-water samples, and these occurred in only one set of periodic samples. Acetaminophen, a nonprescription analgesic, and caffeine were detected in the September source-water samples at concentrations of 0.084 and 0.068 micrograms per liter, respectively. Three other compounds-carbamazepine, an antiepileptic; cotinine, a metabolite of nicotine; and diphenhydramine, a nonprescription antihistamine-were detected in source-water samples, but at concentrations too low to be reliably quantified. None of the 14 pharmaceuticals was found in the finished water at a reportable concentration, defined as two times the long-term detection

  19. Should precise numerical dating overrule glacial geomorphology?

    Science.gov (United States)

    2016-04-01

    Numerical age dating techniques, namely different types of terrestrial cosmogenic nuclide dating (TCND), have achieved an impressive progress in both laboratory precision and regional calibration models during the past few decades. It is now possible to apply precise TCND even to young landforms like Late Holocene moraines, a task seemed hardly achievable just about 15 years ago. An increasing number of studies provide very precise TCND ages for boulders from Late Holocene moraines enabling related reconstruction of glacier chronologies and the interpretation of these glacial landforms in a palaeoclimatological context. These studies may also solve previous controversies about different ages assigned to moraines obtained by different dating techniques, for example relative-age dating techniques or techniques combining relative-age dating with few fixed points derived from numerical age dating. There are a few cases, for example Mueller Glacier and nearby long debris-covered valley glacier in Aoraki/Mt.Cook National Park (Southern Alps, New Zealand), where the apparent "supremacy" of TCND-ages seem to overrule glacial geomorphological principles. Enabled by a comparatively high number of individual boulders precisely dated by TCND, moraine ridges on those glacier forelands have been primarily clustered on basis of these boulder ages rather than on their corresponding morphological position. To the extreme, segments of a particular moraine complex morphologically and sedimentologically proven to be formed during one event have become split and classified as two separate "moraines" on different parts of the glacier foreland. One ledge of another moraine complex contains 2 TCND-sampled boulders apparently representing two separate "moraines"-clusters of an age difference in the order of 1,500 years. Although recently criticism has been raised regarding the non-contested application of the arithmetic mean for calculation of TCND-ages for individual moraines, this

    2002-01-01

    The MINT radiocarbon dating technique was introduced and a very well-designed vacuum line was developed to generate benzene from samples containing carbon. A liquid scintillation counter provides a very good prerequisite for precise measurement of the C-14 activity in the benzene. From time to time, assessment on the status of the analytical capabilities of the system and advice on improvement and upgrading required was made. For routine analysis, standard sampling, pretreatment, carbon dioxide conversion and measurement procedures were adopted. Radiocarbon dating is now, one of the most important developments of the twenties century in the comprehension of the history of human development, a quick, easy, reliable and scientifically acceptable method to determine the age of historical artefacts and archaeological samples.

    1981-09-01

    This report examines one criterion for introducing a commercial FBR: economic competitiveness with a Light Water Reactor (LWR). For this analysis, the commercial FBR is assumed to be the fifth-of-a kind replicate which represents an economically mature plant. This FBR is deemed economically competitive when its life-cycle energy cost is less than or equal to that of an LWR. Results of this analysis are used in a comparative analysis of alternative FBR development stategies. The strategies evaluated in these studies assume both 1000- and 1457-MWe FBRs. Since the capital costs per kilowatt, and therefore the energy costs, for these two FBR sizes are different, they will become economically competitive at different times. The probability density function for the 1457-MW(e) FBR has an expected value date or weighted average date of 2030, compared with 2033 for the probability density function for the 1000-MW(e) FBR

Meaningful developments are traced in this review of C-14 dating by gas proportional (GP) and liquid scintillation (LS) spectrometry. The performance of characteristic as well as state of the art GP and LS systems is tabulated and their merit for low-level counting of C-14 is evaluated. Future developments in radiometry will lie in the updating of existing systems to incorporate new technologies and the refinement of resolution and identification of extreme low-level signals. Parallel development with AMS, sharing on merit the ever widening applied C-14 research field, and enhanced interdisciplinary collaboration are foreseen as the scenario leading to the year 2000

  5. 210Pb dating of Baltic Sea sediments

    Gellermann, R.

    1990-01-01

    The paper reports on the results of 210 Pb measurement in sediment cores from the Baltic Sea. The models used for the interpretation are derived and discussed. In general, the sedimentation parameters calculated with different models are consistent. However, parameters of cores independently taken on same partly show clearly differing values. The reasons of this observation have to be analysed by further studies. An essential problem considered in this paper is the dating of disturbed sediments. The use of such cores for the reconstruction of the input history of chemical indicators requires a deconvolution of data. The response function necessary for this procedure can be derived from 210 Pb measurements. The results of such a reconstruction considerably differ from those obtained by conventional dating models. The analysis of the measuring uncertainty of the indicator (e.g. lead) in the deconvolution procedure unveals the limits of the method and prevents it from overinterpretation. (orig.) [de

    Full Text Available Thessaly in Central Greece is famous for settlement mounds (magoules that were already partly formed in the Early Neolithic period. Some of these long-lived sites grew to many metres in height during the subsequent Middle, Late and Final Neolithic periods, and were also in­habited in the Bronze Age. Such magoules served as the backbone for defining relative chronolo­gical schemes. However, their absolute dating is still a topic of debate: due to a lack of well-defined se­quences, different chronological schemes have been proposed. New radiocarbon dates obtained in the last few years allow a better understanding of the duration not only of the main Neolithic pe­riods, but also of the different phases and sub-phases.

    The radiocarbon dating method using benzene liquid scintillation is reported in detail. The results of measurement of NBS oxalic acid agree with the recommended value, indicating that isotopic fractionation during benzene synthesis can be negligible. Ten samples which have been already measured by gas counter are dated by benzene liquid scintillation. There is no significant difference in age for the same sample between benzene liquid scintillation and gas counters. It is shown that quenching has to be corrected for the young sample. Memory effect in stainless steel reaction vessel can be removed by using an exchangeable inner vessel and by baking it in the air. Using this method, the oldest age that can be measured with 2.3 g carbon is 40,000 years B.P. (author)

  8. Relationship between leukemia incidence and residing and/or working near the Pilgrim 1 nuclear power plant in Plymouth, Massachusetts

    Morris, M.S.

    1992-01-01

    To determine whether a strong association between leukemia incidence between 1978 and 1986 and potential for exposure to radiation emitted from the Pilgrim 1 nuclear power plant in Plymouth, Massachusetts was a spurious finding resulting from either (1) failure to account for temporal variation in the level of radioactivity released from the plant or (2) inattention to certain potentially confounding factors, additional age/sex-matched case-control analyses controlled for the effects of socioeconomic status (SES), work history, and cigarette smoking were performed with data collected in the Southeastern Massachusetts Health Investigation -- a study of leukemia among residents aged 13 and older of 22 southeastern Massachusetts towns. None of the additional analyses, including incorporation of emissions data into the exposure-assessment scheme and crude attempts to control for (1) medical-radiation exposure, (2) potential for exposure to pesticides sprayed on cranberry bogs, or (3) workplace exposure to radiation, chemical solvents, dust, or fumes, altered the finding of a statistically significant dose-response relationship between leukemia incidence and potential for exposure to radioactive emissions. The trend in the association over time was not entirely consistent, however, with the hypothesis that unusually large amounts of radioactivity reportedly released from the plant during the mid-1970s were responsible for the observed effects. Recommendations were made for further study of the Plymouth-area population for studies of this problem elsewhere

    In October 1990 the Massachusetts Department of Public Health released a report of an epidemiologic study of adult leukemia occurring in the vicinity of the Pilgrim 1 Nuclear Power Plant near Plymouth, Massachusetts. The study used a case-control design in which adult leukemia cases occurring between 1978 and 1986 in 22 towns were compared with persons without leukemia (controls) selected from the same study population. Exposure scores, used to estimate potential for exposure to radioactive emissions from Pilgrim, were calculated for all cases and controls. When the exposure scores of cases were compared with those of controls, the analyses showed the scores to be higher for the leukemia cases, suggesting that individuals with the highest potential for exposure to Pilgrim emissions had a significantly increased risk of leukemia. This association was found only for cases diagnosed before 1984; for cases diagnosed during 1984, 1985, or 1986, no association was observed between leukemia case status and potential for exposure to emissions from the plant. Our review of the report and supporting documents shows no major methodologic problems that would account for the finding of an association between leukemia risk and the Pilgrim plant. Examination of the study findings in relation to what is known about leukemia risks associated with radiation exposure, however, indicates that the results of the Southeastern Massachusetts Health Study are inconsistent with a large body of evidence from a number of other studies

    The biggest island in South Korea is Jeju Island, which lies 80 km south of the mainland and has one shield volcano, Mt. Halla. The volcanic island and its lava tubes were added to the world heritage list by UNESCO in 2007. Among the many lava tubes on the island, a unique cave had been accidentally found in 2005 while some workers were replacing a telephone pole. Until the discovery, it had been completely isolated from the outside by naturally-built sand blocks. Yongcheon cave is a lime-decorated lava tube showing both the properties of a volcanic lava tube and a limestone cave. This cave, about 3 km in length, is acknowledged to be the best of this type in the world and includes a large clean-water lake, lava falls, and richly developed speleothems inside it. Even though there is archaeological evidence from well preserved pottery that ancient people entered this place, the preservation of artifacts was ensured by a geological change that made later entrance difficult. We have collected charcoal samples scattered around the cave and dated them using AMS. Ages were in the range of ca. 1570-1260 BP (A.D. 340-880) and this corresponds to the Ancient Three Kingdoms and the Unified Silla era in Korean history. The {sup 14}C AMS measurement results presented in this paper on wood charcoal provide precise dates which will be very useful not only to clarify the nature of human activities in this cave but also to provide reference dates when comparing other dating methods.

    A Geothermal field is usually associated with a volcanic region and, therefore, with an abundance of volcanic glasses such as obsidians. The magmatic chambers constitute an excellent source of heat for a geothermical system. These chambers can be geologically identified from the surface by its recent volcanic products. Therefore, the geological age of the volcanic units is of great interest for a location of a worthwile thermal energy field. This paper presents some preliminary results of the ages obtained by dating obsidians.

    2017-03-01

    This study explores factors that influence matches of online dating participants' stated preference for particular characteristics in a potential partner and compares these with the characteristics of the online daters actually contacted. The nature of online dating facilitates exploration of the differences between stated preference and actual choice by participants, as online daters willingly provide a range of demographics on their ideal partner. Using data from the Australian dating website RSVP, we analyze 219,013 contact decisions. We conduct a multivariate analysis using the number of matched variables between the participants' stated preference and the characteristics of the individuals contacted. We find that factors such as a person's age, their education level, and a more social personality all increase the number of factors they choose in a potential partner that match their original stated preference. Males (relative to females) appear to match fewer characteristics when contacting potential love interests. Conversely, age interaction effects demonstrate that males in their late 60's are increasingly more selective (than females) regarding who they contact. An understanding of how technology (the Internet) is impacting human mating patterns and the psychology behind the participants informs the wider social science of human behavior in large-scale decision settings.

  19. Progress in ESR dating of fossils

    Ikeya, M.

    1983-01-01

    In this review the progress of ESR dating is briefly described together with its historical development. Examples of fossil dating include shells and corals in geological sediments, fossil bones and teeth in anthropology and fossil woods in geology. The total dose of natural radiation (TD) equivalent to the archaeological dose in TL dating was obtained by the additive dose method. Initially, the TDs were plotted against the known ages; using the apparent annual dose-rate thus obtained gives the ESR age within a factor of 2 or 3 for a fossil. Precise assessment of the radiation environment was made later taking the disequilibrium of uranium series disintegration into account. ESR ages of corals agreed well with those obtained by radiocarbon and uranium-thorium methods. The time-independent accumulation rate or a linear accumulation or uranium was adopted as a first sensible model for the opensystem fossil bones: the relation between the TD and the age explains the ages of anthropologically important bones. Lastly, geological assessment of fossil woods was made by ESR based on the organic radicals and electron traps in the silicified part. (author)

    2002-01-01

    The measurement of a radiocarbon date is a complex process which involved all the stages from advice given prior to submission of samples right through to reporting of results. The aim of our radiocarbon dating is to determine the residual 14 C content of a sample, the value of which is translated into an age that is an estimate of the time elapsed since the given sample was removed from the environment in which it had formed in equilibrium with respect to 14-C radioactive decay and metabolic assimilation. Carbon is obtained from carbon containing samples in the form of carbon dioxide, which is then reacted with lithium forming lithium carbide. The carbide is then hydrolysed to acetylene before it was polymerised to benzene using a high-efficiency vanadium-alumina-silica catalyst to produce benzene with up to 96% yield. Sample, background and modem standard activities are measured with a coincidence scintillation counter using in glass vials of 21 ml capacity. An improved chemical procedure was used to obtain and purify the benzene from the samples for measurement using a liquid scintillation counter. Radiocarbon dating measurements of samples collected reveal some results. The validity of the data have yet to be confirmed by the results of the measurements on two international control samples.

  1. Environmental history and dating of coastal dunefields

    International Nuclear Information System (INIS)

    Illenberger, W.K.; Verhagen, B.T.

    1990-01-01

    Sand pulses can be inferred from the geomorphologic evolution of coastal dunefields over the last 6500 years in the eastern Cape Province, South Africa. These pulses correlate with erosion cycles and variation in sea-level, temperature and effective moisture. The concept that sand dunes have a wind memory and represent a record of the wind that blew to produce them can be modified and applied to dunefields: the morphology of dunefields represents an environmental record, going back thousands of years. The carbonate content of eastern Cape coastal sands is biogenic with young coarse carbonate grains constantly being added to the system, resulting in a pronounced negative correlation of radiocarbon age with grain size. It takes thousands of years for an average mollusc shell to be broken to 1-mm-diameter fragments, and a further couple of thousand years to break these sizes down to 0.2-0.3 mm diameter. Eastern Cape coastal dunefields have for the first time been dated definitively via the radiocarbon ages of the carbonate component of the sand. These dunefields have been forming during the past 5000 years or so. Dating wind-blown sand transport is feasible, and correlates with dates inferred from the dunefield morphology. 5 figs., 1 tab., 18 refs

    2003-04-01

    A model of phytoplankton, dissolved oxygen and nutrients is presented and applied to the Charles River, Massachusetts within a framework of Monte Carlo simulation. The model parameters are conditioned using data from eight sampling stations along a 40 km stretch of the Charles River, during a (supposed) steady-state period in the summer of 1996, and the conditioned model is evaluated using data from later in the same year. Regional multi-objective sensitivity analysis is used to identify the parameters and pollution sources most affecting the various model outputs under the conditions observed during that summer. The effects of Monte Carlo sampling error are included in this analysis, and the observations which have least contributed to model conditioning are indicated. It is shown that the sensitivity analysis can be used to speculate about the factors responsible for undesirable levels of eutrophication, and to speculate about the risk of failure of nutrient reduction interventions at a number of strategic control sections. The analysis indicates that phosphorus stripping at the CRPCD wastewater treatment plant on the Charles River would be a high-risk intervention, especially for controlling eutrophication at the control sections further downstream. However, as the risk reflects the perceived scope for model error, it can only be recommended that more resources are invested in data collection and model evaluation. Furthermore, as the risk is based solely on water quality criteria, rather than broader environmental and economic objectives, the results need to be supported by detailed and extensive knowledge of the Charles River problem.

    To describe prescriber response to unsolicited patient reports from the Massachusetts prescription drug monitoring program (PDMP). Prescribers were surveyed upon receipt of unsolicited reports of their patients' prescription history and three months later. We assessed prescribers' awareness of other prescribers listed in the report, their clinical assessment of medical necessity of all prescribed medications, actions taken by prescribers after receiving the report, and usefulness of the report. Of the 333 respondents to the initial survey, only 28 (8.4%) were aware of most, all, or nearly all other prescribers. A total of 146 (43.8%) reported having sufficient knowledge to determine whether the prescriptions were medically necessary, of whom 102 (69.6%) felt the prescriptions were unwarranted. Of the 163 respondents to the follow-up survey, 31.3% added the report to the patient's file, 22.7% discussed the report with other prescribers on the report, 21.5% took no action, and 6% discussed the report with the patient (representing two-thirds of respondents who saw the patient after receiving the report). Most respondents felt that the report was useful for their practice and easy to understand. Unsolicited reporting of PDMP data has the potential to improve clinical practice by alerting providers about patients with multiple prescribers and potentially medically unnecessary prescriptions.

    Given the complex issues associated with plug-in electric vehicle (PEV) charging and options in deploying charging infrastructure, there is interest in exploring scenarios of future charging infrastructure deployment to provide insight and guidance to national and regional stakeholders. The complexity and cost of PEV charging infrastructure pose challenges to decision makers, including individuals, communities, and companies considering infrastructure installations. The value of PEVs to consumers and fleet operators can be increased with well-planned and cost-effective deployment of charging infrastructure. This will increase the number of miles driven electrically and accelerate PEV market penetration, increasing the shared value of charging networks to an expanding consumer base. Given these complexities and challenges, the objective of the present study is to provide additional insight into the role of charging infrastructure in accelerating PEV market growth. To that end, existing studies on PEV infrastructure are summarized in a literature review. Next, an analysis of current markets is conducted with a focus on correlations between PEV adoption and public charging availability. A forward-looking case study is then conducted focused on supporting 300,000 PEVs by 2025 in Massachusetts. The report concludes with a discussion of potential methodology for estimating economic impacts of PEV infrastructure growth.

    Growing evidence that certain poly- and perfluoroalkyl substances (PFASs) are associated with negative human health effects prompted the U.S. Environmental Protection Agency to issue lifetime drinking water health advisories for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in 2016. Given that groundwater is a major source of drinking water, the main objective of this work was to investigate geochemical and hydrological processes governing the subsurface transport of PFASs at a former fire training area (FTA) on Cape Cod, Massachusetts, where PFAS-containing aqueous film-forming foams were used historically. A total of 148 groundwater samples and 4 sediment cores were collected along a 1200-m-long downgradient transect originating near the FTA and analyzed for PFAS content. The results indicate that unsaturated zones at the FTA and at hydraulically downgradient former domestic wastewater effluent infiltration beds both act as continuous PFAS sources to the groundwater despite 18 and 20 years of inactivity, respectively. Historically different PFAS sources are evident from contrasting PFAS composition near the water table below the FTA and wastewater-infiltration beds. Results from total oxidizable precursor assays conducted using groundwater samples collected throughout the plume suggest that some perfluoroalkyl acid precursors at this site are transporting with perfluoroalkyl acids.

    To examine the extent to which a clinical intervention resulted in reduced BMI z scores among 2- to 12-year-old children compared to routine practice (treatment as usual [TAU]). The Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project is a multifaceted initiative to prevent childhood obesity among low-income children. At the federally qualified community health centers (FQHCs) of two communities (Intervention Site #1 and #2), the following were implemented: (1) pediatric weight management training, (2) electronic decision supports for clinicians, (3) on-site Healthy Weight Clinics, (4) community health worker integration, and (5) healthful clinical environment changes. One FQHC in a demographically matched community served as the TAU site. Using electronic health records, we assessed BMI z scores and used linear mixed models to examine BMI z score change over 2 years in each intervention site compared to a TAU site. Compared to children in the TAU site (n = 2,286), children in Intervention Site #2 (n = 1,368) had a significant decline in BMI z scores following the start of the intervention (-0.16 units/y; 95% confidence interval: -0.21 to -0.12). No evidence of an effect was found in Intervention Site #1 (n = 111). The MA-CORD clinical interventions were associated with modest improvement in BMI z scores in one of two intervention communities compared to a TAU community. © 2017 The Obesity Society.

    Through communication-and-resolution programs, hospitals and liability insurers communicate with patients when adverse events occur; investigate and explain what happened; and, where appropriate, apologize and proactively offer compensation. Using data recorded by program staff members and from surveys of involved clinicians, we examined case outcomes of a program used by two academic medical centers and two of their community hospitals in Massachusetts in the period 2013-15. The hospitals demonstrated good adherence to the program protocol. Ninety-one percent of the program events did not meet compensation eligibility criteria, and those events that did were not costly to resolve (the median payment was $75,000). Only 5 percent of events led to malpractice claims or lawsuits. Clinicians were supportive of the program but desired better communication about it from staff members. Our findings suggest that communication-and-resolution programs will not lead to higher liability costs when hospitals adhere to their commitment to offer compensation proactively.

    Double stud walls have a higher risk of interior-sourced condensation moisture damage when compared with high-R approaches using exterior insulating sheathing. In this project, Building Science Corporation monitored moisture conditions in double-stud walls from 2011 through 2014 at a new production house located in Devens, Massachusetts. The builder, Transformations, Inc., has been using double-stud walls insulated with 12 in. of open cell polyurethane spray foam (ocSPF); however, the company has been considering a change to netted and blown cellulose insulation for cost reasons. Cellulose is a common choice for double-stud walls because of its lower cost (in most markets). However, cellulose is an air-permeable insulation, unlike spray foams, which increases interior moisture risks. The team compared three double-stud assemblies: 12 in. of ocSPF, 12 in. of cellulose, and 5-½ in. of ocSPF at the exterior of a double-stud wall (to approximate conventional 2 × 6 wall construction and insulation levels, acting as a control wall). These assemblies were repeated on the north and south orientations, for a total of six assemblies.

  11. The Massachusetts Toxics Use Reduction Act: a model for nanomaterials regulation?

    International Nuclear Information System (INIS)

    Nash, Jennifer

    2012-01-01

    Nanomaterials exemplify a new class of emerging technologies that have significant economic and social value, pose uncertain health and environmental risks, and are entering the marketplace at a rapid pace. Effective regimes for regulating emerging technologies generate information about known or suspected hazards and draw on private sector expertise to guide managers’ behavior toward risk reduction, even in the absence of clear evidence of harm. This paper considers the extent to which the federal Toxic Substances Control Act (TSCA) accomplishes those objectives. It offers the approach of the Massachusetts Toxics Use Reduction Act (TURA) as a possible supplement to TSCA, filling gaps in agency knowledge and private sector capacities. TURA is notable for its focus on chemicals use and hazard and its emphasis on strengthening firms’ internal management systems. Given the current deadlock in Congressional efforts to modernize federal laws such as TSCA, the role of state laws like TURA merit attention. Absent definitive information about risk, a governance strategy that generates information and focuses management attention on reducing hazards is worth considering.

    We evaluated the impact of the 3-year Healthy Futures program on reducing sexual behaviors among middle school students. Fifteen public middle schools in Haverhill, Lowell, and Lynn, Massachusetts, participated in this longitudinal school-cluster randomized controlled trial (2011-2015), which included 1344 boys and girls. We collected student survey data at baseline, immediately after each Nu-CULTURE curriculum (classroom component of Healthy Futures) in the sixth, seventh, and eighth grades, and at a 1-year follow-up in the ninth grade (cohort 1 students only). Healthy Futures did not reduce the overall prevalence of eighth-grade students who reported ever having vaginal sex. In the eighth-grade follow-up, fewer girls in the treatment group than in the control group reported ever having vaginal sex (P = .04), and fewer Hispanic treatment students than Hispanic control students reported ever having vaginal sex (P = .002). There was some evidence of delaying sexual initiation by the end of Nu-CULTURE, for girls and Hispanics, but not for boys. Future research should focus on improving implementation of the supplemental components intended to foster interpersonal and environmental protective factors associated with sustained delays in sexual activity.

    2004-01-01

    An extensive investigation at the Camp Edwards, Massachusetts Military Reservation (MMR) demonstrates that assessment of groundwater and soil contamination at military ranges can be limited primarily to explosive-related compounds such as RDX, HMX, perchlorate, TNT and their transformation products. A modified analytical method is recommended to expand the list of explosives and to improve the detection limits. Analyses of metals, VOCs, SVOCs, and TICs are unnecessary. Soil samples may require the analyses of PAHs and PCNs for burn areas. Camp Edwards, as one of the few military ranges that have been exhaustively investigated for contaminants, is an ideal point of departure for evaluating other ranges. The permeable site soils promote leaching of contaminants and inhibit biotic and abiotic transformations. Moreover, the site has experienced an unusual extent of activities in its more than ninety years of active use. The recommendations in this report are based on data obtained for more than 200 analytes from more than 15,000 environmental samples. - Assessment of groundwater and soil contamination at US military ranges can be limited primarily to explosive-related compounds

    In the early morning of Dec. 16, 1991, a severe accident occurred when a passenger vehicle traveling in the wrong direction collided with a tractor trailer carrying 24 unirradiated nuclear fuel assemblies in 12 containers on Interstate I-91 in Springfield, Massachusetts. The purpose of this report is to document the mechanical circumstances of the severe accident, confirm the nature and quantity of the radioactive materials involved, and assess the physical environment to which the containers were exposed and the response of the containers and their contents. The report consists of five major sections. The first section describes the circumstances and conditions of the accident and the finding of facts. The second describes the containers, the unirradiated nuclear fuel assemblies, and the tie down arrangement used for the trailer. The third describes the damage sustained during the accident to the tractor, trailer, containers, and unirradiated nuclear fuel assemblies. The fourth evaluates the accident environment and its effects on the containers and their contents. The final section gives conclusions derived from the analysis and fact finding investigation. During this severe accident, only minor injuries occurred, and at no time was the public health and safety at risk

    A detailed description is given of the laws and programs of the State of Massachusetts governing the regulation of public energy utilities, the siting of energy generating and transmission facilities, the municipal franchising of public energy utilities, and the prescription of rates to be charged by utilities including attendant problems of cost allocations, rate base and operating expense determinations, and rate of return allowances. These laws and programs are analyzed to identify impediments which they may present to the implementation of Integrated Community Energy Systems (ICES). This report is one of fifty-one separate volumes which describe such regulatory programs at the Federal level and in each state as background to the report entitled Community Energy Systems and the Law of Public Utilities - Volume One: An Overview. This report also contains a summary of a strategy described in Volume One - An Overview for overcoming these impediments by working within the existing regulatory framework and by making changes in the regulatory programs to enhance the likelihood of ICES implementation.

    2001-01-01

    The species composition and relative abundance of aquatic macrophytes was evaluated in five Cape Cod, Massachusetts, freshwater kettle ponds, representing a range of trophic conditions from oligotrophic to eutrophic. At each pond, aquatic vegetation and environmental variables (slope, water depth, sediment bulk density, sediment grain size, sediment organic content and porewater inorganic nutrients) were measured along five transects extending perpendicular to the shoreline from the upland border into the pond. Based on a variety of multivariate methods, including Detrended Correspondence Analysis (DCA), an indirect gradient analysis technique, and Canonical Correspondence Analysis (CCA), a direct gradient approach, it was determined that the eutrophic Herring Pond was dominated by floating aquatic vegetation (Brasenia schreberi, Nymphoides cordata, Nymphaea odorata), and the algal stonewort, Nitella. Partial CCA suggested that high porewater PO4-P concentrations and fine-grained sediments strongly influenced the vegetation of this eutrophic pond. In contrast, vegetation of the oligotrophic Duck Pond was sparse, contained no floating aquatics, and was dominated by emergent plants. Low porewater nutrients, low sediment organic content, high water clarity and low pH (4.8) best defined the environmental characteristics of this oligotrophic pond. Gull Pond, with inorganic nitrogen-enriched sediments, also exhibited a flora quite different from the oligotrophic Duck Pond. The species composition and relative abundance of aquatic macrophytes provide good indicators of the trophic status of freshwater ponds and should be incorporated into long-term monitoring programs aimed at detecting responses to anthropogenically-derived nutrient loading.

    OBJECTIVE: To examine whether the obesity prevalence is increasing, level, or decreasing among young US children (aged children) at a multisite pediatric practice in eastern Massachusetts during 1999–2008. By using the Centers for Disease Control and Prevention 2000 gender-specific growth charts, we defined obesity as weight-for-length ≥95th percentile for children aged children aged 24 to obesity trends in 2 separate periods, 1999–2003 and 2004–2008, adjusting for age group, race/ethnicity, health insurance, and practice site. RESULTS: From 1999 to 2003, the obesity prevalence was fairly stable among both boys and girls. From 2004 to 2008, the obesity prevalence substantially decreased among both boys and girls. The decline in obesity prevalence during 2004–2008 was more pronounced among children insured by non-Medicaid health plans than among those insured by Medicaid. CONCLUSIONS: Among children aged obesity prevalence decreased during 2004–2008, which is in line with national data showing no increase in prevalence during this time period. The smaller decrease among Medicaid-insured children may portend widening of socioeconomic disparities in childhood obesity. PMID:22529276

  18. Relationship between recycling rate and air pollution: Waste management in the state of Massachusetts.

    This study examines the relationship between recycling rate of solid waste and air pollution using data from a waste municipality survey in the state of Massachusetts during the period 2009-2012. Two econometric approaches are applied. The first approach is a fixed effects model, while the second is a Stochastic Frontier Analysis (SFA) with fixed effects model. The advantage of the first approach is the ability of controlling for stable time invariant characteristics of the municipalities, thereby eliminating potentially large sources of bias. The second approach is applied in order to estimate the technical efficiency and rank of each municipality accordingly. The regressions control for various demographic, economic and recycling services, such as income per capita, population density, unemployment, trash services, Pay-as-you-throw (PAYT) program and meteorological data. The findings support that a negative relationship between particulate particles in the air 2.5 μm or less in size (PM2.5) and recycling rate is presented. In addition, the pollution is increased with increases on income per capita up to $23,000-$26,000, while after this point income contributes positively on air quality. Finally, based on the efficiency derived by the Stochastic Frontier Analysis (SFA) model, the municipalities which provide both drop off and curbside services for trash, food and yard waste and the PAYT program present better performance regarding the air quality.

    Healthy, productive employees are an integral part of school health programs. There have been few assessments of work productivity among secondary school staff. This study describes the frequency of 3 common health risk factors--obesity, depressive symptoms, and smoking--and their impact on work productivity in secondary school employees. Employees of secondary schools in Massachusetts (N = 630) participated in a longitudinal weight gain prevention intervention study. Assessment completed at baseline, 1-year and 2-year follow-up included survey assessments of health risk factors as well as measurements for height, weight, and body mass index (BMI). The survey also included a depression inventory and Work Limitations Questionnaire. Data analysis included multivariate mixed effect models to identify productivity differences in relation to BMI, depressive symptoms, and smoking in this population stratified by position type (teacher and other school staff). The sample included 361 teachers and 269 other school staff. Obesity, depressive symptoms, and smoking were significantly associated with work productivity, including workdays missed because of health concerns (absenteeism) and decreases in on-the-job productivity because of health concerns (presenteeism). Three common health conditions, namely obesity, depressive symptoms, and smoking, adversely affect the productivity of high school employees. © 2015, American School Health Association.

    Moving to the ASHRAE Standard 90.1-2013 (ASHRAE 2013) edition from Standard 90.1-2010 (ASHRAE 2010) is cost-effective for the State of Massachusetts. The table below shows the state-wide economic impact of upgrading to Standard 90.1-2013 in terms of the annual energy cost savings in dollars per square foot, additional construction cost per square foot required by the upgrade, and life-cycle cost (LCC) per square foot. These results are weighted averages for all building types in all climate zones in the state, based on weightings shown in Table 4. The methodology used for this analysis is consistent with the methodology used in the national cost-effectiveness analysis. Additional results and details on the methodology are presented in the following sections. The report provides analysis of two LCC scenarios: Scenario 1, representing publicly-owned buildings, considers initial costs, energy costs, maintenance costs, and replacement costs—without borrowing or taxes. Scenario 2, representing privately-owned buildings, adds borrowing costs and tax impacts.
