Wzrost zainteresowania problematyką zaburzeń odżywiania jest uzasadniony ze względu na jednostkowe, ale i społeczne konsekwencje wynikające z nieprawidłowości w obszarze realizowania potrzeby pokarmowej. Ponadto dane epidemiologiczne wskazują na zwiększanie się liczebności oraz spadek wieku osób z objawami zaburzeń łaknienia. Przyczyn tego może być wiele, ponieważ anoreksja ma wieloczynnikowe podłoże. W literaturze przedmiotu podkreśla się znaczenie relacji w rodzinach anorektycznych. Realiz...

Full Text Available Co zmieniło się we Francji w zarządzaniu ryzykiem powodziowym na wybrzeżach po sztormie Xynthia. W rok po sztormie Xynthia, który w nocy z 27 na 28 lutego 2010 roku w tragiczny sposób dotknął departamenty Vendée i Charente-Maritime francuskiego wybrzeża Atlantyku, władze wprowadziły krajowy plan ograniczania skutków szybkich powodzi (MEDDTL 2011. Dotyczy on także sposobów zarządzania zalewami morskimi. W niniejszym artykule analizowano częściowe wyniki realizacji tego planu oraz jego skuteczności w perspektywie katastrofy Xynthia oraz w świetle innych dramatycznych powodzi przybrzeżnych, które wystąpiły w okresie zimowym 2013/2014 w Bretanii. Jedną z długoterminowych lekcji, która należy wyciągnąć z Xynthii, jest pilna potrzeba całkowitej zmiany gospodarki przestrzennej nadbrzeżnych osiedli, która od ponad dwóch wieków nie miała wiele wspólnego z zasadami zrównoważonego rozwoju. Sam żywioł i jego następstwa objawiły również słabą świadomość ryzyka powodziowego na terenach przybrzeżnych i głęboki brak odpowiedzialności zbiorowej zarówno władz samorządowych, jak i administracji.

Możliwości polderyzacji obszaru zawala w rejonie Stężycy nad Wisłą

Full Text Available Temat ochrony przeciwpowodziowej, w tym polderów, jest zwykle podnoszony przy okazji każdej większej powodzi i po pewnym czasie, gdy zastosowano już doraźne środki naprawcze, dyskusja cichnie. Poldery jako obiekty hydrotechniczne, mające za zadanie przejąć szczyt fali powodziowej, wzbudzają wiele przeciwstawnych emocji. Z jednej strony uważa się, że są to obiekty, które mogą skutecznie uzupełniać system ochrony przeciwpowodziowej i pozytywnie wpływać na środowisko przyrodnicze. Z drugiej strony wysokie koszty, niska efektywność i wiele innych elementów sprawiają, że nie jest to popularna forma ochrony przed powodzią. W części obliczeniowej pracy skupiono się na nieistniejącym polderze w Stężycy o całkowitej pojemności równej około 24 mln m3. Model odcinka Wisły z uwzględnieniem istnienia polderu wykonano w programie HEC-RAS. Obliczenia dotyczyły szybkości napełniania tego zbiornika przy trzech różnych wariantach przepływu nieustalonego i przy różnych długościach przelewu na wlocie do polderu. Symulacje wykazały, że w krytycznym przypadku niezbędny byłby wlot o długości ok. 400 m, aby w całości napełnić polder podczas trwania wezbrania. W drugiej części pracy podjęto dyskusję na temat pozytywnych i negatywnych aspektów budowy polderów.

Charakterystyczne dla każdego nacjonalizmu, każdej struktury ideologicznej (ale nie tylko, jest to, że się rozszerza, w naszym przypadku – szuka swoich początków coraz bardziej wstecz w czasie. Proces ten można zaobserwować i w konstrukcjach nacjonalizmu bułgarskiego, ale z o wiele późniejszego okresu. W drugiej połowie XX wieku i na początku XXI wieku widać wyraźny zwrot ku czasom sprzed rządów założyciela chana Asparucha (VII w., tj. kiedy powstawały inne bułgarskie organizmy państwowe (zob. Р. Даскалов, Чудният свят на прабългарите, София 2011. Natomiast przed wyzwoleniem (1878 i powstaniem Księstwa Bułgarii można zaobserwować tendencję przeciwną. Przedstawiciele ruchu rewolucyjnego, a przynajmniej część z nich, odrzuca okres średniowiecza i kieruje swą uwagę ku innym początkom, o wiele bliższym w czasie, nawet pokrywającym się czasem aktualnym lub wręcz odnoszącym się do niedalekiej przyszłości. Wyobrażenie to – mniej lub bardziej nieoczekiwa­nie – zostało zreaktualizowane przez często powtarzającą pod koniec XX wieku frazę „czas najbardziej bułgarski” (E. Karanfiłow, odsyłającą do lat 70.

Wiele zawodów – jedna waga? O zróżnicowaniu kosztów kształcenia zawodowego

2016-03-01

Full Text Available W artykule podjęto problematykę publicznego finansowania edukacji zawodowej w Polsce. Na podstawie danych pochodzących z Systemu Informacji Oświatowej z 2012 r. przeanalizowano wydatki bieżące na ucznia w zasadniczych szkołach zawodowych i technikach. Wyniki analiz stawiają pod znakiem zapytania efektywność algorytmu finansowania szkół kształcących zawodowo w Polsce, który nie różnicuje wysokości subwencji w zależności od oferty nauczanych zawodów oraz sposobu organizacji praktycznej nauki zawodu. Może to mieć niebagatelne znaczenie w przypadku mniej zamożnych organów prowadzących szkoły. Jak wynika z analiz, wydatki bieżące na ucznia są zróżnicowane w zależności od obszaru kształcenia zawodowego. Istnieją istotne różnice w poziomie wydatków szkół kształcących w obszarze rolniczo-leśnym z ochroną środowiska w stosunku do szkół kształcących w mniej kosztownych zawodach z obszaru ekonomiczno-administracyjnego. Ponadto szkoły, które kształcą młodych pracowników oraz organizują praktyczną naukę zawodu poza placówką, np. w centrach kształcenia praktycznego, ponoszą istotnie niższe wydatki na ucznia niż pozostałe. Analizy ukazały również odmienne realia finansowania kształcenia zawodowego przez miasta na prawach powiatu i uboższe powiaty ziemskie. Zróżnicowanie wydatków jest wyraźniejsze w przypadku miast, które posiadają zasoby finansowe pozwalające na swobodniejsze kształtowanie wydatków w zależności od specyficznych potrzeb szkół kształcących w różnych zawodach. Oznacza to, że wydatki na kształcenie zawodowe bogatszych samorządów mogą stanowić lepsze przybliżenie realnych kosztów kształcenia w zależności od zawodu.

Full Text Available W klasyfikacjach ICD-10 i DSM-IV zespół Aspergera należy do kategorii całościowych zaburzeń rozwoju. Nie w pełni zdefiniowane kryteria diagnostyczne są przedmiotem dyskusji badaczy i klinicystów. W nowym systemie klasyfikacji – DSM-5 – zespół Aspergera nie występuje, pojawiła się za to szeroka jednostka „spektrum zaburzeń autystycznych”. Do najpowszechniejszych objawów zespołu Aspergera zalicza się: zaburzenia komunikacji werbalnej i niewerbalnej, egocentryzm, upośledzenie umiejętności społecznych, stereotypowość zachowań, zawężenie zainteresowań, problemy z koordynacją. Manifestacja symptomów zmienia się w ciągu życia – z powodu wzrastających wymagań społecznych objawy stają się wyraźniejsze w okresie dorastania. Świadomość bycia innym prowadzi do pogłębiającego się wycofania. Postawienie właściwej diagnozy jest szczególnie trudne u osób dorosłych. Wielu pacjentów psychiatrycznych, w których przypadku istnieją duże trudności z ustaleniem rozpoznania, cierpi na – wcześniej niezdiagnozowany – zespół Aspergera. Jego objawy bywają błędnie rozpoznawane jako symptomy zaburzeń osobowości czy schizofrenii. Co więcej, wiele zaburzeń może współwystępować z zespołem Aspergera (np. zaburzenia obsesyjno-kompulsyjne, zaburzenia afektywne, schizofrenia, zaburzenia odżywiania. Agresja, uzależnienia, myśli i tendencje samobójcze także mogą zaciemniać jego objawy. Podsumowując: istnieje wiele zaburzeń współwystępujących i problemów towarzyszących, które utrudniają rozpoznanie omawianego zespołu u dorosłych.

Full Text Available Harmonizacja rachunkowości finansowej jest procesem przynoszącym wiele korzyści, ale także generującym poważne zagrożenia. Wśród pozytywnych stron harmonizacji wymienić należy: wzmocnienie funkcji alokacyjnej rynków kapitałowych, wzrost zaufania inwestorów do sprawozdań finansowych, rozszerzenie możliwości pozyskiwania kapitału pożyczkowego, obniżenie kosztów funkcjonowania korporacji międzynarodowych. Towarzyszące harmonizacji zjawiska niepożądane to: wyeliminowanie porównywalności sprawozdań finansowych na poziomie krajowym, przekreślenie znacznej części dorobku szkoły kontynentalnej rachunkowości, ustanowienie monopolu w tworzeniu standardów, zanik normatywnego nurtu badań w rachunkowości.

W pracy zanalizowano główne problemy związane z zagrożeniem powodziowym w dolinie przedgórskiego odcinka Wisły (południowa Polska. Ten odcinek rzeki podlega pracom regulacyjnym od połowy XIX wieku. Omówiono wiele problemów wpisujących się w główny nurt dyskusji na temat efektywności stosowanych metod regulacji rzek. Główną uwagę zwrócono na: (1 aktualny stan zagrożenia powodziowego, (2 wielkość odpływu rzeki, (3 zmiany w zagrożeniu powodziowym od początku prac regulacyjnych z uwzględnieniem zmian w geometrii koryta i zmian w wielkości odpływu rzeki odzwierciedlających efekty prac regulacyjnych. Za główną cechę hydrologiczną badanego odcinka Wisły należy uznać znaczny od zapoczątkowania prac regulacyjnych wzrost wielkości przepływu pełnokorytowego, który trwa nadal. Oznacza to, że zmniejsza się ilość wody w rzece, która podczas stanów wyższych od stanu pełnokorytowego może zatapiać strefę międzywala. Tą uwagę uznano za podstawę analizy zmian w zagrożeniu powodziowym w przedgórskim odcinku Wisły. Ocenę tych zmian w badanym odcinku rzeki nie można jednak uznać za jednoznaczną, gdyż niektóre zmiany w warunkach odpływu przyczyniają się do zmniejszenia ryzyka powodzi, podczas gdy inne są odpowiedzialne za jego zwiększenie. W pracy wykorzystano dane z ponad 100-letniego okresu udostępnione przez Państwową Służbę Hydrologiczną, uwzględniono również mapy opublikowane w dużej skali w ostatnich 230 latach, a także wyniki badań terenowych autora.

Wybrane aspekty wpływu asymetrii funkcjonalnej półkul mózgowych na funkcjonowanie poznawcze oraz emocjonalne człowieka

Full Text Available Przez wiele lat asymetria półkul mózgowych rozpatrywana była jako wyraźny podział funkcjonalny. W tym dychotomicznym modelu badacze wiązali półkulę lewą wyłącznie z funkcjami werbalnymi, a prawą – ze zdolnościami niewerbalnymi. Podział ten jest jednak niewyczerpujący i zdecydowanie upraszcza tematykę specjalizacji półkul mózgowych. Najnowsze doniesienia wskazują na współpracę i zarazem pewną niezależność międzypółkulową w zakresie kontroli funkcjonowania człowieka. Ponadto podkreśla się, że różnice funkcjonalne istnieją, ale są znacznie subtelniejsze, niż zakładano na początku badań dotyczących tej tematyki. Aby ułatwić zrozumienie istoty asymetrii funkcjonalnej, stworzono modele, które wyjaśniały mechanizm specjalizacji półkulowej i odrębność stylów przetwarzania bodźców. Dane potwierdzające istnienie asymetrii funkcjonalnej półkul pochodzą m.in. z doniesień o jednostronnych uszkodzeniach mózgu, agenezji spoidła wielkiego, zabiegach komisurotomii czy hemisferektomii. Na tej podstawie dokonano analizy funkcjonowania kognitywnego i emocjonalnego pacjentów. Wykryto pewne prawidłowości dotyczące różnic i podobieństw w funkcjonowaniu półkul mózgowych w zakresie percepcji wzrokowej, funkcji werbalnych, praksji, uwagi, pamięci i uczenia się czy funkcji wykonawczych. Jeśli chodzi o lateralizację emocji w mózgu, pojawia się wiele sprzecznych doniesień. Potrzebne są dalsze, dobrze zaprojektowane badania, które pomogą zrozumieć, czy istnieje lateralizacja emocji w mózgu, a jeśli tak, to jakich aspektów funkcjonowania afektywnego ona dotyczy. Niniejsza praca przedstawia przegląd poglądów na wpływ asymetrii półkul mózgowych na funkcjonowanie poznawcze, emocjonalne i behawioralne człowieka.

Wpro‑ wadzenie leków przeciwpsychotycznych zahamowało jednak ten nurt badań, bowiem od tej pory koncentrowano się wyłącznie na objawach zaburzeń ruchowych powstałych w wyniku stosowania neuroleptyków. W kilku pracach wy‑ kazano również, że niektóre zaburzenia ruchowe są częstsze i bardziej nasilone u krewnych I stopnia osób chorych, lecz rzadsze i mniej nasilone niż u chorych na schizofrenię. Obecnie istnieje wiele narzędzi – skal klinicznych, używa‑ nych w praktyce i badaniach, opartych na obserwacji klinicznej, służących do oceny występowania i nasilenia zabu‑ rzeń motorycznych zarówno spontanicznych, jak i związanych z leczeniem lekami przeciwpsychotycznymi. Najczęściej przy pomocy tych skal ocenia się i monitoruje objawy parkinsonizmu, dystonie oraz akatyzję.

Instrumentalne metody oceny zaburzeń ruchowych (spontanicznych i spowodowanych leka‑ mi przeciwpsychotycznymi pozwalają na wykrycie właśnie subtelnych, słabo nasilonych objawów i dlatego mogą być przydatne przy identyfikacji osób z tzw. stanem wysokiego ryzyka rozwoju psychozy, ocenie występowania dysfunkcji motorycznych u krewnych osób chorych na schizofrenię, a także określaniu stopnia i rodzaju odpowiedzi na leczenie lekami przeciwpsychotycznymi.

Climate change and precipitation: Detecting changes Climate change and precipitation: Detecting changes

International Nuclear Information System (INIS)

Van Boxel, John H

2001-01-01

Precipitation is one of the most, if not the most important climate parameter In most studies on climate change the emphasis is on temperature and sea level rise. Often too little attention is given to precipitation. For a large part this is due to the large spatial en temporal variability of precipitation, which makes the detection of changes difficult. This paper describes methods to detect changes in precipitation. In order to arrive at statistically significant changes one must use long time series and spatial averages containing the information from several stations. In the Netherlands the average yearly precipitation increased by 11% during the 20th century .In the temperate latitudes on the Northern Hemisphere (40-60QN) the average increase was about 7% over the 20th century and the globally averaged precipitation increased by about 3%. During the 20th century 38% of the land surface of the earth became wetter, 42% experienced little change (less than 5% change) and 20% became dryer. More important than the average precipitation is the occurrence of extremes. In the Netherlands there is a tendency to more extreme precipitations, whereas the occurrence of relatively dry months has not changed. Also in many other countries increases in heavy precipitation events are observed. All climate models predict a further increase of mean global precipitation if the carbon dioxide concentration doubles. Nevertheless some areas get dryer, others have little change and consequently there are also areas where the increase is much more than the global average. On a regional scale however there are large differences between the models. Climate models do not yet provide adequate information on changes in extreme precipitations

Highlights: ► We show development of flood policy frames in context of climate change attention. ► Rising attention on climate change influences traditional flood policy framing. ► The new framing employs global-scale scientific climate change knowledge. ► With declining attention, framing disregards climate change, using local knowledge. ► We conclude that frames function as sensemaking devices selectively using knowledge. -- Abstract: Water management and particularly flood defence have a long history of collective action in low-lying countries like the Netherlands. The uncertain but potentially severe impacts of the recent climate change issue (e.g. sea level rise, extreme river discharges, salinisation) amplify the wicked and controversial character of flood safety policy issues. Policy proposals in this area generally involve drastic infrastructural works and long-term investments. They face the difficult challenge of framing problems and solutions in a publicly acceptable manner in ever changing circumstances. In this paper, we analyse and compare (1) how three key policy proposals publicly frame the flood safety issue, (2) the knowledge referred to in the framing and (3) how these frames are rhetorically connected or disconnected as statements in a long-term conversation. We find that (1) framings of policy proposals differ in the way they depict the importance of climate change, the relevant timeframe and the appropriate governance mode; (2) knowledge is selectively mobilised to underpin the different frames and (3) the frames about these proposals position themselves against the background of the previous proposals through rhetorical connections and disconnections. Finally, we discuss how this analysis hints at the importance of processes of powering and puzzling that lead to particular framings towards the public at different historical junctures

Zaburzenia odżywiania, takie jak ortoreksja, anoreksja, pregorekscja, bulimia czy otyłość to nieprawidłowe zachowania w obszarze nawyków żywieniowych, które prowadzą do znacznych zakłóceń masy ciała. Stanowią istotny problem zdrowotny, który dotyka głównie dziewczęta oraz młode kobiety, powodujący wiele negatywnych konsekwencji zarówno zdrowotnych, psychologicznych, jak i społecznych dla osoby chorej. Złożona etiologia zaburzeń odżywiania wymaga interdyscyplinarnego podejścia, uwzględniającego m. in. modyfikację stylu życia, w szczególności zachowań żywieniowych, wsparcie psychologiczne czy postępowanie farmakologiczne.     ABSTRACT Recent years have seen an increase in the occurrence of eating disorders in Western countries, with sociocultural changes being one of the main reasons for this trend. Eating disorders, such as anorexia, pregorexia, bulimia or obesity, are abnormal behaviours related to eating habits, which lead to serious disturbances in body weight. They are a major health problem mostly in girls and young women, negatively affecting their physical health, mental condition and social life in many different ways. The complex etiology of eating disorders requires an interdisciplinary approach, including methods such as change of lifestyle, in particular eating habits, psychological support and pharmacological treatment.

ENGLISH ABSTRACT: Omni-directionality is the ability of a mobile robot to move instantaneously in any direction. This paper describes the wheel and controller designs of a Mecanumwheeled, autonomous guided vehicle (AGV for reconfigurable manufacturing systems. Mecanum wheels use slip developed between rollers and surface, surface and ground, to achieve omni-directionality. An advantage of omni-directional robotic platforms is that they are capable of performing tasks in congested environments such as those found in factory workshops, narrow aisles, warehouses, etc. Controller Area Network (CAN is implemented as a distributed controller to control motion and navigation tasks of the developed robot. The design of the distributed controller is described and its performance analyzed. This increases the reliability and functionality of the mobile robot.

Full Text Available This article explains the change management process and resistance to organizational change through examining causes of resistance to change, diagnosing them, and finding the ways to deal with resistance to change. In business environment, the one thing any company can be assured of is change. If an organization experiences change it may also need to implement new business strategies, which can create resistance among employees. Managers need to know in which phase they have to expect unusual situations, problems, and resistance to change. Most successful organizations are those that are able to adjust themselves to new conditions quickly. Preparing for change, managing change through resistance management plan and reinforcing change have been identified in the article as the main phrases of change management process that lead to improve the organization performance. Managing resistance to change is important part for success of any change effort in each company. Dealing with resistance in large part will depend on timely recognition of the real causes of resistance to change and finding the ways to reduce, overcome or eliminate the resistance to change. Developing efficient ways to introduce and implement change can ease the stress the staff feels when change is introduced. Different resistance states, causes of change resistance and forms of change resistance have been emphasized in the change management process. The proposed diagnosing model has been used to identify significant and weighty causes of resistance to change by using the expert survey and ranking causes of resistance to change. The ways to reduce and overcome resistance to change have been explained.

iSeeChange: Crowdsourced Climate Change Reporting

2012-12-01

Directly engaging local communities about their climate change experiences has never been more important. As weather and climate become more unpredictable, these experiences provide a baseline for community decisions, developing adaptation strategies, and planning for the future. Typically, climate change is documented in a top-down fashion: a scientist has a question, makes observations, and publishes a study; in the best case scenario, a journalist reports on the results; if there's time, a local anecdote is sought to put the results in a familiar context. iSeeChange, a public media project funded by the Corporation for Public Broadcasting, reports local environmental change in reverse and turns community questions and conversations with scientists into reported stories that promote opportunities to learn about climate change's affects on the environment and daily life. iSeeChange engages residents of the North Fork Valley region of western Colorado in a multiplatform conversation with scientists about how they perceive their environment is changing through the course of a year - season to season. By bringing together public radio, a mobile reporting and cellular engagement strategy, and a custom crowdsourcing multimedia platform, iSeeChange provides a central access point to collect observations (texts, photographs, voice recordings, and video), organize conversations and interviews with scientists, and report stories online and on air. In this way, iSeeChange is building a dynamic crowdsourced reservoir of information that can increase awareness of environmental problems and potentially disseminate useful information about climate change and successful adaptation strategies. Ultimately, by understanding the community's information needs in a localized question-driven context, the iSeeChange platform presents opportunities for the science community to better understand the value of information and develop better ways to tailor information for communities to use

Changes in requirements may result in the increasing of product development project cost and lead time, therefore, it is important to understand how requirement changes propagate in the design of complex product systems and be able to select best options to guide design. Currently, a most approach for design change is lack of take the multi-disciplinary coupling relationships and the number of parameters into account integrally. A new design change model is presented to systematically analyze and search change propagation paths. Firstly, a PDS-Behavior-Structure-based design change model is established to describe requirement changes causing the design change propagation in behavior and structure domains. Secondly, a multi-disciplinary oriented behavior matrix is utilized to support change propagation analysis of complex product systems, and the interaction relationships of the matrix elements are used to obtain an initial set of change paths. Finally, a rough set-based propagation space reducing tool is developed to assist in narrowing change propagation paths by computing the importance of the design change parameters. The proposed new design change model and its associated tools have been demonstrated by the scheduling change propagation paths of high speed train's bogie to show its feasibility and effectiveness. This model is not only supportive to response quickly to diversified market requirements, but also helpful to satisfy customer requirements and reduce product development lead time. The proposed new design change model can be applied in a wide range of engineering systems design with improved efficiency.

Stages of Geoinformation Evolution Related to the Territories Described in the Bible - from the 3Rd Millennium B.C. to Modern Times

Linsenbarth, Adam

2012-09-01

The paper presents consecutive stages of the evolution of geoinformation related to the territories of the events described in the Bible. Two geoinformation sources are presented: the Bible and non-Bible sources. In the Bible there is much, often some highly detailed information regarding terrain topography. The oldest non-Bible sources are incorporated in the ancient documents, which were discovered in Egypt and Mesopotamia. Some of them are related to the 3rd millen- nium B.C. The further stages are related to the onomasticons and itineraries written by travellers and pilgrims to the Holy Land. The most famous onomasticons include: onomasticons prepared by bishop Eusebius from Caesarea and those pre- pared by St. Jerome. One of the oldest maps of Palestine's territory is the so-called mosaic map of Madaba dated to 565. In the 15th century several Bible maps were edited. The most rapid evolution occurred in the 16th and 17* centuries, when the world famous cartographers such as Mercator and Ortelius edited several maps of Palestine's territory. Cartographers from several European countries edited more than 6,000 maps presenting the Biblical territories and Biblical events. Modem maps, based on detailed topographical surveys, were edited m the second half of the 19* and 20th centuries. W artykule przedstawiono kolejne etapy rozwoju geoinformacji dotyczącej terenówr biblijnych. Omówiono dwa źródła informacji, a mianowicie geoinformacje biblijne i pozabiblijne. W tekstach biblijnych można znaleźć wiele, często bardzo detalicznych informacji topograficznych. Najstarsze źródła pozabiblijne, to starożytne dokumenty odnalezione na terenach Egiptu i Mezopotamii. Niektóre z nich pochodzą z trzeciego milenium przed Chr. Kolejnym etapem geoinformacji były onomastikony oraz dzienniki podróży pisane przez podróżników i pielgrzymów do Ziemi Świętej. Do najbardziej znanych należy onomastikon sporządzony przez biskupa Euzebiusza z Cezarei oraz

Scaling Climate Change Communication for Behavior Change

Ultimately, effective climate change communication results in a change in behavior, whether the change is individual, household or collective actions within communities. We describe two efforts to promote climate-friendly behavior via climate communication and behavior change theory. Importantly these efforts are designed to scale climate communication principles focused on behavior change rather than soley emphasizing climate knowledge or attitudes. Both cases are embedded in rigorous evaluations (randomized controlled trial and quasi-experimental) of primary and secondary outcomes as well as supplementary analyses that have implications for program refinement and program scaling. In the first case, the Girl Scouts "Girls Learning Environment and Energy" (GLEE) trial is scaling the program via a Massive Open Online Course (MOOC) for Troop Leaders to teach the effective home electricity and food and transportation energy reduction programs. The second case, the Alliance for Climate Education (ACE) Assembly Program, is advancing the already-scaled assembly program by using communication principles to further engage youth and their families and communities (school and local communities) in individual and collective actions. Scaling of each program uses online learning platforms, social media and "behavior practice" videos, mastery practice exercises, virtual feedback and virtual social engagement to advance climate-friendly behavior change. All of these communication practices aim to simulate and advance in-person train-the-trainers technologies.As part of this presentation we outline scaling principles derived from these two climate change communication and behavior change programs.

Change the World by Changing Economics

Full Text Available We live in a world of opportunity – the opportunity to use the insight generated through the multiple crises humanity finds itself in to transit into a much more liveable, sustainable and equitable society. A paradigm change seems to be taking place, a movement for change seems to be in the making, but at the same time there is a widespread feeling that things are getting worse instead of better and there is no guarantee that change will lead us into a better future in the next few decades. To effectively guide the direction of change we need to address the root causes of today’s global challenges and take a close look at what drives human society and human beings. In doing so we realize that we are looking at a holographic picture which contains different layers, which are interdependent: Human biology; values and belief systems; the changing narrative underlying the development of human society; economics and governance and the many tools as well as special interests, support and uphold the outdated paradigms. The one element which influences all people nearly every day and is behind just about each and every crisis is the theory and practice of current economics. The article explores the debate on current economics and proposes mechanisms of change.

Results of the MATRIC (Management of Technology Responses to the Climate Change Challenge) project are summarized. The project empirically studied technological change and innovation to learn more about the contingencies conditioning and influencing these processes with the aim to recommend national technology oriented climate change policies. The first chapter explains the background, the central research question, the structure and the methodology of Matric. The central research question was how to modulate the ongoing dynamics of socio-technical change to the climate change needs. Chapter two summarizes the core of the analytical framework of Matric. The fundamental idea of social embedding of technology has been the analytical point of departure of the Matric project. It says that innovations emerge and technology changes in close interaction with its social environment. The social environment turns out to be a strong conditioner of technological change and development and therefore, technology and its embedding social environment tend to co-evolve in the course of time. Co-evolution of technology and its social environment theoretically draws on evolutionary oriented economics and sociology. Both theoretical traditions are in turn inspired by biologically oriented. Chapter three summarizes the empirical findings of the analysis of socio-technical change patterns in three cases: electricity generation and use, car-based transport and mobility and eco-efficiency in industrial production. The cases have been selected for their climate change impact and for their social and economic significance. Chapter four comparatively analyzes the significance of the analytical and empirical findings of Matric for the central research question of the project. The chapter comparatively analysis the general pattern of the development, the change and development of the socio-technical regimes, the socio-technical governance arrangements and processes and the public policy

Changing fields of rationality - a policy for change?

Strumse, Einar; Westskog, Hege; Winther, Tanja

2010-07-01

Work objective: To analyze effective strategies for changing households' energy consumption based on an interdisciplinary model for understanding change. Methodology: In this paper we develop a conceptual model for understanding individuals' energy consumption. We synthesize insights from anthropology, social psychology and economics grasping perspectives from behaviour to practice and from the Bourdieu's fields to rationality thinking in economics. We use this insight to analyze strategies for change. Abstract: In this paper we analyze effective strategies for changing households' energy consumption based on an interdisciplinary model for understanding change. The model focuses on four main categories for understanding individual consumption: a. Material constraints b. Values and identity c. Norms d. Ability These are the main influencing factors of the individual's consumption level, but in interaction with the corresponding group and the societal levels for the same factors. The model can be illustrated. One combination of factors on all levels constitutes a field of rationality. We claim that an important strategy for changing energy consumption towards sustainability is changing the field of rationality of the individual. Changing of rationality fields would from our point of view initiate reflection which is an important condition for changed behavior. One example of changing of fields is information measures that relates energy consumption to the 'citizen' field rather than the 'consumer' field. Hence, according to our conceptual framework - how policy should be framed (information measures for instance ) would be an important knowledge area for design of effective policy measures. (Author)

Assessing sensitivity to change: choosing the appropriate change coefficient

Full Text Available Abstract The past 20-years have seen the development and evaluation of many health status measures. Unlike the high standards demanded of those who conduct and report clinical intervention trials, the methodological rigor for studies examining the sensitivity to change of health status measures are less demanding. It is likely that the absence of a criterion standard for change in health status contributes to this shortcoming. To increase confidence in the results of these types of studies investigators have often calculated multiple change coefficients for the same patient sample. The purpose of this report is to identify the conflict that arises when multiple change coefficients are applied to the same patient sample. Three families of change coefficients based on different assumptions concerning the sample composition are identified: (1 the sample is homogeneous with respect to change; (2 subgroups of patients who truly change by different amounts exist; (3 individual patients, many of whom truly change by different amounts exist. We present several analyses which illustrate a major conceptual conflict: the signal (a measure's true ability to detect change for some of these coefficients appears in the noise term (measurement error of the others. We speculate that this dilemma occurs as a result of insufficient preparatory work such as pilot studies to establish the likely change characteristic of the patient population of interest. Uncertainty in the choice of change coefficient could be overcome by conducting pilot studies to ascertain the likely change characteristic of the population of interest. Once the population's change characteristic is identified, the choice of change coefficient should be clear.

Organizational readiness to change may be a key determinant of implementation success and a mediator of the effectiveness of implementation interventions. If organizational readiness can be reliably and validly assessed at the outset of a change initiative, it could be used to assess the effectiveness of implementation-support activities by measuring changes in readiness factors over time. We analyzed two waves of readiness-to-change survey data collected as part of a three-arm, randomized controlled trial to implement evidence-based health promotion practices in small worksites in low-wage industries. We measured five readiness factors: context (favorable broader conditions); change valence (valuing health promotion); information assessment (demands and resources to implement health promotion); change commitment (an intention to implement health promotion); and change efficacy (a belief in shared ability to implement health promotion). We expected commitment and efficacy to increase at intervention sites along with their self-reported effort to implement health promotion practices, termed wellness-program effort. We compared means between baseline and 15 months, and between intervention and control sites. We used linear regression to test whether intervention and control sites differed in their change-readiness scores over time. Only context and change commitment met reliability thresholds. Change commitment declined significantly for both control (-0.39) and interventions sites (-0.29) from baseline to 15 months, while context did not change for either. Only wellness program effort at 15 months, but not at baseline, differed significantly between control and intervention sites (1.20 controls, 2.02 intervention). Regression analyses resulted in two significant differences between intervention and control sites in changes from baseline to 15 months: (1) intervention sites exhibited significantly smaller change in context scores relative to control sites

Rigorous Photogrammetric Processing of CHANG'E-1 and CHANG'E-2 Stereo Imagery for Lunar Topographic Mapping

Science.gov (United States)

Di, K.; Liu, Y.; Liu, B.; Peng, M.

2012-07-01

Chang'E-1(CE-1) and Chang'E-2(CE-2) are the two lunar orbiters of China's lunar exploration program. Topographic mapping using CE-1 and CE-2 images is of great importance for scientific research as well as for preparation of landing and surface operation of Chang'E-3 lunar rover. In this research, we developed rigorous sensor models of CE-1 and CE-2 CCD cameras based on push-broom imaging principle with interior and exterior orientation parameters. Based on the rigorous sensor model, the 3D coordinate of a ground point in lunar body-fixed (LBF) coordinate system can be calculated by space intersection from the image coordinates of con-jugate points in stereo images, and the image coordinates can be calculated from 3D coordinates by back-projection. Due to uncer-tainties of the orbit and the camera, the back-projected image points are different from the measured points. In order to reduce these inconsistencies and improve precision, we proposed two methods to refine the rigorous sensor model: 1) refining EOPs by correcting the attitude angle bias, 2) refining the interior orientation model by calibration of the relative position of the two linear CCD arrays. Experimental results show that the mean back-projection residuals of CE-1 images are reduced to better than 1/100 pixel by method 1 and the mean back-projection residuals of CE-2 images are reduced from over 20 pixels to 0.02 pixel by method 2. Consequently, high precision DEM (Digital Elevation Model) and DOM (Digital Ortho Map) are automatically generated.

Full Text Available This paper uses the World Trade Model with Climate Sensitive Land (WTMCL to evaluate possible future land-use changes associated with adaptations to climate change in a globalized world. In this approach, changes in regional agricultural production, which are based on comparative advantage, define patterns of land use change in agriculture in all regions of the world. We evaluate four scenarios that combine assumptions about future increases in food demand and future changes in land endowments of different productivities associated with climatic conditions: each scenario generates distinct patterns of regional specialization in the production of agricultural commodities and associated land-use change. The analysis also projects future food availability under the simulated conditions and the direction of likely changes in prices of the major agricultural commodity groups.

This chapter summarises recent quantitative research on phonetic variation and change in Received Pronunciation (RP) as an elite sociolect, the vernacular of a multiplex socio-economically privileged group in the UK. The ‘elite sociolect’ is distinct from the ‘standard variety’, a term which should...... be reserved to refer to a socially generated mental ‘construct’, a set of expressed and tacit norms for ‘status-bearing’ language practice learned through the educational system and evident in the public domain. The chapter discusses variationist findings on word-final /t/, prevocalic /r/ and a range of vowel...... qualities. It also addresses evidence of sociolinguistic change, in the form of ongoing de-standardisation processes in the speech community of England, as well as the changing language-ideological and language-attitudinal place of RP in the sociolinguistic landscape....

RIGOROUS PHOTOGRAMMETRIC PROCESSING OF CHANG'E-1 AND CHANG'E-2 STEREO IMAGERY FOR LUNAR TOPOGRAPHIC MAPPING

Full Text Available Chang'E-1(CE-1 and Chang'E-2(CE-2 are the two lunar orbiters of China's lunar exploration program. Topographic mapping using CE-1 and CE-2 images is of great importance for scientific research as well as for preparation of landing and surface operation of Chang'E-3 lunar rover. In this research, we developed rigorous sensor models of CE-1 and CE-2 CCD cameras based on push-broom imaging principle with interior and exterior orientation parameters. Based on the rigorous sensor model, the 3D coordinate of a ground point in lunar body-fixed (LBF coordinate system can be calculated by space intersection from the image coordinates of con-jugate points in stereo images, and the image coordinates can be calculated from 3D coordinates by back-projection. Due to uncer-tainties of the orbit and the camera, the back-projected image points are different from the measured points. In order to reduce these inconsistencies and improve precision, we proposed two methods to refine the rigorous sensor model: 1 refining EOPs by correcting the attitude angle bias, 2 refining the interior orientation model by calibration of the relative position of the two linear CCD arrays. Experimental results show that the mean back-projection residuals of CE-1 images are reduced to better than 1/100 pixel by method 1 and the mean back-projection residuals of CE-2 images are reduced from over 20 pixels to 0.02 pixel by method 2. Consequently, high precision DEM (Digital Elevation Model and DOM (Digital Ortho Map are automatically generated.

Human-induced climate change: the impact of land-use change

Science.gov (United States)

Gries, Thomas; Redlin, Margarete; Ugarte, Juliette Espinosa

2018-02-01

For hundreds of years, human activity has modified the planet's surface through land-use practices. Policies and decisions on how land is managed and land-use changes due to replacement of forests by agricultural cropping and grazing lands affect greenhouse gas emissions. Agricultural management and agroforestry and the resulting changes to the land surface alter the global carbon cycle as well as the Earth's surface albedo, both of which in turn change the Earth's radiation balance. This makes land-use change the second anthropogenic source of climate change after fossil fuel burning. However, the scientific research community has so far not been able to identify the direction and magnitude of the global impact of land-use change. This paper examines the effects of net carbon flux from land-use change on temperature by applying Granger causality and error correction models. The results reveal a significant positive long-run equilibrium relationship between land-use change and the temperature series as well as an opposing short-term effect such that land-use change tends to lead to global warming; however, a rise in temperature causes a decline in land-use change.

Indigenous Arctic and Subarctic communities currently are facing a myriad of social and environmental changes. In response to these changes, studies concerning indigenous knowledge (IK) and climate change vulnerability, resiliency, and adaptation have increased dramatically in recent years. Risks to lives and livelihoods are often the focus of adaptation research; however, the cultural dimensions of climate change are equally important because cultural dimensions inform perceptions of risk. Furthermore, many Arctic and Subarctic IK climate change studies document observations of change and knowledge of the elders and older generations in a community, but few include the perspectives of the younger population. These observations by elders and older generations form a historical baseline record of weather and climate observations in these regions. However, many indigenous Arctic and Subarctic communities are composed of primarily younger residents. We focused on the differences in the cultural dimensions of climate change found between young adults and elders. We outlined the findings from interviews conducted in four indigenous communities in Subarctic Alaska. The findings revealed that (1) intergenerational observations of change were common among interview participants in all four communities, (2) older generations observed more overall change than younger generations interviewed by us, and (3) how change was perceived varied between generations. We defined “observations” as the specific examples of environmental and weather change that were described, whereas “perceptions” referred to the manner in which these observations of change were understood and contextualized by the interview participants. Understanding the differences in generational observations and perceptions of change are key issues in the development of climate change adaptation strategies.

Minimal changes in health status questionnaires: distinction between minimally detectable change and minimally important change

Directory of Open Access Journals (Sweden)

Knol Dirk L

2006-08-01

Full Text Available Abstract Changes in scores on health status questionnaires are difficult to interpret. Several methods to determine minimally important changes (MICs have been proposed which can broadly be divided in distribution-based and anchor-based methods. Comparisons of these methods have led to insight into essential differences between these approaches. Some authors have tried to come to a uniform measure for the MIC, such as 0.5 standard deviation and the value of one standard error of measurement (SEM. Others have emphasized the diversity of MIC values, depending on the type of anchor, the definition of minimal importance on the anchor, and characteristics of the disease under study. A closer look makes clear that some distribution-based methods have been merely focused on minimally detectable changes. For assessing minimally important changes, anchor-based methods are preferred, as they include a definition of what is minimally important. Acknowledging the distinction between minimally detectable and minimally important changes is useful, not only to avoid confusion among MIC methods, but also to gain information on two important benchmarks on the scale of a health status measurement instrument. Appreciating the distinction, it becomes possible to judge whether the minimally detectable change of a measurement instrument is sufficiently small to detect minimally important changes.

Changing scenes: memory for naturalistic events following change blindness.

Science.gov (United States)

Mäntylä, Timo; Sundström, Anna

2004-11-01

Research on scene perception indicates that viewers often fail to detect large changes to scene regions when these changes occur during a visual disruption such as a saccade or a movie cut. In two experiments, we examined whether this relative inability to detect changes would produce systematic biases in event memory. In Experiment 1, participants decided whether two successively presented images were the same or different, followed by a memory task, in which they recalled the content of the viewed scene. In Experiment 2, participants viewed a short video, in which an actor carried out a series of daily activities, and central scenes' attributes were changed during a movie cut. A high degree of change blindness was observed in both experiments, and these effects were related to scene complexity (Experiment 1) and level of retrieval support (Experiment 2). Most important, participants reported the changed, rather than the initial, event attributes following a failure in change detection. These findings suggest that attentional limitations during encoding contribute to biases in episodic memory.

Westerberg, Kristina; Tafvelin, Susanne

2015-07-06

The purpose of the this study was to explore the development of commitment to change among leaders in the home help services during organizational change and to study this development in relation to workload and stress. During organizational change initiatives, commitment to change among leaders is important to ensure the implementation of the change. However, little is known of development of commitment of change over time. The study used a qualitative design with semi-structured interviews with ten leaders by the time an organizational change initiative was launched and follow-up one year later. Thematic content analysis was used to analyze the interviews. Commitment to change is not static, but seems to develop over time and during organizational change. At the first interview, leaders had a varied pattern reflecting different dimensions of commitment to change. One year later, the differences between leaders' commitment to change was less obvious. Differences in commitment to change had no apparent relationship with workload or stress. The data were collected from one organization, and the number of participants were small which could affect the results on workload and stress in relation to commitment to change. It is important to support leaders during organizational change initiatives to maintain their commitment. One way to accomplish this is to use management team meetings to monitor how leaders perceive their situation. Qualitative, longitudinal and leader studies on commitment to change are all unusual, and taken together, this study shows new aspects of commitment.

The present research investigated the longitudinal relations between personality traits and narratives. Specifically, the authors examined how individual differences in 170 college students' narratives of personality change (a) were predicted by personality traits at the beginning of college, (b) related to actual changes and perceived changes in personality traits during college, and (c) related to changes in emotional health during college. Individual differences in narratives of personality trait change told in the 4th year of college fell into 2 dimensions: affective processing, characterized by positive emotions, and exploratory processing, characterized by meaning making and causal processing. Conscientious, open, and extraverted freshmen told exploratory stories of change as seniors. Emotionally healthy freshmen told stories of change that were high in positive affect. Both positive affective and exploratory stories corresponded to change in emotional stability and conscientiousness during college above and beyond the effects of perceived changes in these traits. In addition, both positive affective and exploratory narratives corresponded to increases in emotional health during college independent of the effects of changes in personality traits. These findings improve our understanding of how individuals conceptualize their changing identity over time.

Rendezvous with Toutatis from the Moon: The Chang'e-2 mission

Chang'e-2 probe was the second lunar probe of China, with the main objectives to demonstrate some key features of the new lunar soft landing technology, and its applications to future exploration missions. After completing the planned mission successfully, Chang'e-2 flew away from the Moon and entered into the interplanetary space. Later, at a distance of 7 million km from the Earth, Chang'e-2 encountered asteroid (4179) Toutatis with a very close fly-by distance and obtained colorful images with a 3-m resolution. Given some surplus velocity increment as well as the promotion of autonomous flight ability and improvement of control, propulsion, and thermal systems in the initial design, Chang'e-2 had the capabilities necessary for escaping from the Moon. By taking advantage of the unique features of the Lagrangian point, the first close fly-by of asteroid Toutatis was realized despite the tight constraints of propellant allocation, spacecraft-Earth communication, and coordination of execution sequences. Chang'e-2 realized the Toutatis flyby with a km-level distance at closest approach. In the absence of direct measurement method, based on the principle of relative navigation and through the use of the sequence of target images, we calculated the rendezvous parameters such as relative distance and image resolution. With the help of these parameters, some fine and new scientific discoveries about the asteroid were obtained by techniques of optical measurements and image processing. Starting with an innovative design, followed by high-fidelity testing and demonstration, elaborative implementation, and optimal usage of residual propellant, Chang'e-2 has for the first time successfully explored the Moon, L2 point and an asteroid, while achieving the purpose of 'faster, better, cheaper'. What Chang'e-2 has accomplished was far beyond our expectations. *J. Huang is the chief designer (PI) of Chang'e-2 probe, planned Chang'e-2's multi-objective and multitasking exploration

Latent change models of adult cognition: are changes in processing speed and working memory associated with changes in episodic memory?

Hertzog, Christopher; Dixon, Roger A; Hultsch, David F; MacDonald, Stuart W S

2003-12-01

The authors used 6-year longitudinal data from the Victoria Longitudinal Study (VLS) to investigate individual differences in amount of episodic memory change. Latent change models revealed reliable individual differences in cognitive change. Changes in episodic memory were significantly correlated with changes in other cognitive variables, including speed and working memory. A structural equation model for the latent change scores showed that changes in speed and working memory predicted changes in episodic memory, as expected by processing resource theory. However, these effects were best modeled as being mediated by changes in induction and fact retrieval. Dissociations were detected between cross-sectional ability correlations and longitudinal changes. Shuffling the tasks used to define the Working Memory latent variable altered patterns of change correlations.

Future changes in extratropical storm tracks and baroclinicity under climate change

2014-01-01

The weather in Eurasia, Australia, and North and South America is largely controlled by the strength and position of extratropical storm tracks. Future climate change will likely affect these storm tracks and the associated transport of energy, momentum, and water vapour. Many recent studies have analyzed how storm tracks will change under climate change, and how these changes are related to atmospheric dynamics. However, there are still discrepancies between different studies on how storm tracks will change under future climate scenarios. Here, we show that under global warming the CMIP5 ensemble of coupled climate models projects only little relative changes in vertically averaged mid-latitude mean storm track activity during the northern winter, but agree in projecting a substantial decrease during summer. Seasonal changes in the Southern Hemisphere show the opposite behaviour, with an intensification in winter and no change during summer. These distinct seasonal changes in northern summer and southern winter storm tracks lead to an amplified seasonal cycle in a future climate. Similar changes are seen in the mid-latitude mean Eady growth rate maximum, a measure that combines changes in vertical shear and static stability based on baroclinic instability theory. Regression analysis between changes in the storm tracks and changes in the maximum Eady growth rate reveal that most models agree in a positive association between the two quantities over mid-latitude regions.

If Canada intends to meet its greenhouse gas reduction target of 6 per cent below 1990 levels, a fundamental shift in energy use by Canadians is required. The health sector will also be required to change. Global climate change is expected to affect regions differently, some might get wetter, some might get warmer, and others still might get colder. Climate changes will influence a number of health determinants: the geographical range of disease organisms and vectors; temperature extremes and violent weather events; air, food and water quality; the stability of ecosystems. There is a requirement to strongly regulate the emissions of carbon dioxide, methane and other greenhouse gases to limit health risks. Increased air pollution could negatively affect large numbers of people, especially asthma sufferers and people suffering from chronic respiratory ailments and cardiovascular diseases. Changes in precipitation and temperature could increase insect-borne diseases. Water sources could be badly affected by drought, flooding or increased glacial runoff. The thinning of the ozone layer could result in additional skin cancers, impaired vision and other diseases. The document explores the various impacts resulting from climate change. A chapter is devoted to each topic: air pollution, temperature extremes, extreme weather events, vector borne diseases, drought and increased evaporation, food supply and ecosystem range, sea level rise, stratospheric ozone depletion and describes the health impacts. In addition, a chapter deals with aboriginal communities. The topic of environmental refugees is discussed, followed by an historical perspective into climate change policy in Canada. The author concludes with adaptation measures. Further emphasis must be placed on priority topics such as the estimation of future emissions and modelling of climate processes. refs., tabs., figs

As the effects of climate change become more profound, climate literacy becomes increasingly important. The American Meteorological Society (AMS) responds to this need through the publication of Our Changing Climate and Living With Our Changing Climate. Both publications incorporate the latest scientific understandings of Earth's climate system from reports such as IPCC AR5 and the USGCRP's Third National Climate Assessment. Topic In Depth sections appear throughout each chapter and lead to more extensive, multidisciplinary information related to various topics. Additionally, each chapter closes with a For Further Exploration essay, which addresses specific topics that complement a chapter concept. Web Resources, which encourage additional exploration of chapter content, and Scientific Literature, from which chapter content was derived can also be found at the conclusion of each chapter. Our Changing Climate covers a breadth of topics, including the scientific principles that govern Earth's climate system and basic statistics and geospatial tools used to investigate the system. Released in fall 2015, Living With Our Changing Climate takes a more narrow approach and investigates human and ecosystem vulnerabilities to climate change, the role of energy choices in affecting climate, actions humans can take through adaption, mitigation, and policy to lessen vulnerabilities, and psychological and financial reasons behind climate change denial. While Living With Our Changing Climate is intended for programs looking to add a climate element into their curriculum, Our Changing Climate is part of the AMS Climate Studies course. In a 2015 survey of California University of Pennsylvania undergraduate students using Our Changing Climate, 82% found it comfortable to read and utilized its interactive components and resources. Both ebooks illuminate the multidisciplinary aspect of climate change, providing the opportunity for a more sustainable future.

OPPORTUNITY TO REDUCE RESISTANCE TO CHANGE IN A PROCESS OF ORGANIZATIONAL CHANGE

Full Text Available This paper aims to present the research results conducted on several models of organizational change regarding the identification of the appropriate moment in which the managers interest should turn towards the reduction of the employees resistance to change. More specifically, we intend to identify when is the best moment to reduce the resistance to change, depending on the change we want to achieve. After more research of organizational change models, we have reached the following conclusions: -not all models of organizational change present reducing resistance to change as a necessary stage; -the place of this phase in the models of organizational change is not considered to be the same; -some models of organizational change recommend indirectly reducing employee resistance to change by indicating the use of some methods, techniques, processes that would lead to this result. Here we include mainly: communication, training, positive motivation of employees; -we recommended that the place of this stage should vary depending on the desired change to achieve; -in strategic changes, which are extremely important for an organization and which affect a large number of employees, we recommend that the reduction of the employee resistance to change be achieved before passing to the implementation of the plan developed to implement the change; -in imposed changes, in conditions of crisis when we have no time available to plan the change, immediately after it had been implemented it is necessary to conduct effective actions meant to ensure, even if the change has been made, the reduction of the resistance to change of the affected employees -to achieve time savings in the process of organizational change, we recommend that after having obtained a certain attachment of some employees to change, the implementation of the methods, of the techniques that would increase their commitment to continue to be developed in parallel with the implementation of the

USGS science for the Nation's changing coasts; shoreline change assessment

Thieler, E. Robert; Hapke, Cheryl J.

2011-01-01

The coastline of the United States features some of the most popular tourist and recreational destinations in the world and is the site of intense residential, commercial, and industrial development. The coastal zone also has extensive and pristine natural areas, with diverse ecosystems providing essential habitat and resources that support wildlife, fish, and human use. Coastal erosion is a widespread process along most open-ocean shores of the United States that affects both developed and natural coastlines. As the coast changes, there are a wide range of ways that change can affect coastal communities, habitats, and the physical characteristics of the coast?including beach erosion, shoreline retreat, land loss, and damage to infrastructure. Global climate change will likely increase the rate of coastal change. A recent study of the U.S. Mid-Atlantic coast, for example, found that it is virtually certain that sandy beaches will erode faster in the future as sea level rises because of climate change. The U.S. Geological Survey (USGS) is responsible for conducting research on coastal change hazards, understanding the processes that cause coastal change, and developing models to predict future change. To understand and adapt to shoreline change, accurate information regarding the past and present configurations of the shoreline is essential. A comprehensive, nationally consistent analysis of shoreline movement is needed. To meet this national need, the USGS is conducting an analysis of historical shoreline changes along open-ocean coasts of the conterminous United States and parts of Alaska and Hawaii, as well as the coasts of the Great Lakes.

Previous research findings display that after having seen popular climate change films, people became more concerned, more motivated and more aware of climate change, but changes in behaviors were short-term. This article performs a meta-analysis of three popular climate change films, The Day after Tomorrow (2005), An Inconvenient Truth (2006), and The Age of Stupid (2009), drawing on research in social psychology, human agency, and media effect theory in order to formulate a rationale about how mass media communication shapes our everyday life experience. This article highlights the factors with which science blends in the reception of the three climate change films and expands the range of options considered in order to encourage people to engage in climate change mitigation actions. © The Author(s) 2014.

Reliable change indices (RCIs) and standardized regression-based (SRB) change score norms permit evaluation of meaningful changes in test scores following treatment interventions, like epilepsy surgery, while accounting for test-retest reliability, practice effects, score fluctuations due to error, and relevant clinical and demographic factors. Although these methods are frequently used to assess cognitive change after epilepsy surgery in adults, they have not been widely applied to examine cognitive change in children with epilepsy. The goal of the current study was to develop RCIs and SRB change score norms for use in children with epilepsy. Sixty-three children with epilepsy (age range: 6-16; M=10.19, SD=2.58) underwent comprehensive neuropsychological evaluations at two time points an average of 12 months apart. Practice effect-adjusted RCIs and SRB change score norms were calculated for all cognitive measures in the battery. Practice effects were quite variable across the neuropsychological measures, with the greatest differences observed among older children, particularly on the Children's Memory Scale and Wisconsin Card Sorting Test. There was also notable variability in test-retest reliabilities across measures in the battery, with coefficients ranging from 0.14 to 0.92. Reliable change indices and SRB change score norms for use in assessing meaningful cognitive change in children following epilepsy surgery are provided for measures with reliability coefficients above 0.50. This is the first study to provide RCIs and SRB change score norms for a comprehensive neuropsychological battery based on a large sample of children with epilepsy. Tables to aid in evaluating cognitive changes in children who have undergone epilepsy surgery are provided for clinical use. An Excel sheet to perform all relevant calculations is also available to interested clinicians or researchers. Copyright © 2015 Elsevier Inc. All rights reserved.

Measuring Historical Coastal Change using GIS and the Change Polygon Approach

Smith, M.J.; Cromley, R.G.

2012-01-01

This study compares two automated approaches, the transect-from-baseline technique and a new change polygon method, for quantifying historical coastal change over time. The study shows that the transect-from-baseline technique is complicated by choice of a proper baseline as well as generating transects that intersect with each other rather than with the nearest shoreline. The change polygon method captures the full spatial difference between the positions of the two shorelines and average coastal change is the defined as the ratio of the net area divided by the shoreline length. Although then change polygon method is sensitive to the definition and measurement of shoreline length, the results are more invariant to parameter changes than the transect-from-baseline method, suggesting that the change polygon technique may be a more robust coastal change method. ?? 2012 Blackwell Publishing Ltd.

Climate for Change?

DEFF Research Database (Denmark)

Wejs, Anja

Cities rather than national governments take the lead in acting on climate change. Several cities have voluntarily created climate change plans to prevent and prepare for the effects of climate change. In the literature climate change has been examined as a multilevel governance area taking place...... around international networks. Despite the many initiatives taken by cities, existing research shows that the implementation of climate change actions is lacking. The reasons for this scarcity in practice are limited to general explanations in the literature, and studies focused on explaining...... the constraints on climate change planning at the local level are absent. To understand these constraints, this PhD thesis investigates the institutional dynamics that influence the process of the integration of climate change into planning practices at the local level in Denmark. The examination of integration...

Forcings and feedbacks by land ecosystem changes on climate change

Science.gov (United States)

Betts, R. A.

2006-12-01

Vegetation change is involved in climate change through both forcing and feedback processes. Emissions of CO{2} from past net deforestation are estimated to have contributed approximately 0.22 0.51 Wm - 2 to the overall 1.46 Wm - 2 radiative forcing by anthropogenic increases in CO{2} up to the year 2000. Deforestation-induced increases in global mean surface albedo are estimated to exert a radiative forcing of 0 to -0.2 Wm - 2, and dust emissions from land use may exert a radiative forcing of between approximately +0.1 and -0.2 Wm - 2. Changes in the fluxes of latent and sensible heat due to tropical deforestation are simulated to have exerted other local warming effects which cannot be quantified in terms of a Wm - 2 radiative forcing, with the potential for remote effects through changes in atmospheric circulation. With tropical deforestation continuing rapidly, radiative forcing by surface albedo change may become less useful as a measure of the forcing of climate change by changes in the physical properties of the land surface. Although net global deforestation is continuing, future scenarios used for climate change prediction suggest that fossil fuel emissions of CO{2} may continue to increase at a greater rate than land use emissions and therefore continue to increase in dominance as the main radiative forcing. The CO{2} rise may be accelerated by up to 66% by feedbacks arising from global soil carbon loss and forest dieback in Amazonia as a consequence of climate change, and Amazon forest dieback may also exert feedbacks through changes in the local water cycle and increases in dust emissions.

Pigeons (Columba livia) show change blindness in a color-change detection task.

Herbranson, Walter T; Jeffers, Jacob S

2017-07-01

Change blindness is a phenomenon whereby changes to a stimulus are more likely go unnoticed under certain circumstances. Pigeons learned a change detection task, in which they observed sequential stimulus displays consisting of individual colors back-projected onto three response keys. The color of one response key changed during each sequence and pecks to the key that displayed the change were reinforced. Pigeons showed a change blindness effect, in that change detection accuracy was worse when there was an inter-stimulus interval interrupting the transition between consecutive stimulus displays. Birds successfully transferred to stimulus displays involving novel colors, indicating that pigeons learned a general change detection rule. Furthermore, analysis of responses to specific color combinations showed that pigeons could detect changes involving both spectral and non-spectral colors and that accuracy was better for changes involving greater differences in wavelength. These results build upon previous investigations of change blindness in both humans and pigeons and suggest that change blindness may be a general consequence of selective visual attention relevant to multiple species and stimulus dimensions.

The fate of object memory traces under change detection and change blindness.

Science.gov (United States)

Busch, Niko A

2013-07-03

Observers often fail to detect substantial changes in a visual scene. This so-called change blindness is often taken as evidence that visual representations are sparse and volatile. This notion rests on the assumption that the failure to detect a change implies that representations of the changing objects are lost all together. However, recent evidence suggests that under change blindness, object memory representations may be formed and stored, but not retrieved. This study investigated the fate of object memory representations when changes go unnoticed. Participants were presented with scenes consisting of real world objects, one of which changed on each trial, while recording event-related potentials (ERPs). Participants were first asked to localize where the change had occurred. In an additional recognition task, participants then discriminated old objects, either from the pre-change or the post-change scene, from entirely new objects. Neural traces of object memories were studied by comparing ERPs for old and novel objects. Participants performed poorly in the detection task and often failed to recognize objects from the scene, especially pre-change objects. However, a robust old/novel effect was observed in the ERP, even when participants were change blind and did not recognize the old object. This implicit memory trace was found both for pre-change and post-change objects. These findings suggest that object memories are stored even under change blindness. Thus, visual representations may not be as sparse and volatile as previously thought. Rather, change blindness may point to a failure to retrieve and use these representations for change detection.

Climate change (including climate variability) refers to regional or global changes in mean climate state or in patterns of climate variability over decades to millions of years often identified using statistical methods and sometimes referred to as changes in long-term weather conditions (IPCC, 2012). Climate is influenced by changes in continent-ocean configurations due to plate tectonic processes, variations in Earth’s orbit, axial tilt and precession, atmospheric greenhouse gas (GHG) concentrations, solar variability, volcanism, internal variability resulting from interactions between the atmosphere, oceans and ice (glaciers, small ice caps, ice sheets, and sea ice), and anthropogenic activities such as greenhouse gas emissions and land use and their effects on carbon cycling.

As human activity adds more greenhouse gases to the atmosphere, most climate change scenarios predict rising temperatures and decreased rainfall in the east of New Zealand. This means eastern parts of the country are expected to experience more droughts as the 21st century goes on. Our report seeks for the first time to define the possible range of changes in future drought risk. This report was commissioned because of the importance of drought for agriculture and water resources. The report aims to give central and local government and the agriculture sector an indication of how big future drought changes could be in the various regions. This information can be relevant in managing long-term water resources and land use, including planning for irrigation schemes.

Changing Educational Traditions with the Change Laboratory

Directory of Open Access Journals (Sweden)

Louis Royce Botha

2017-07-01

Full Text Available This paper outlines the use of a form of research intervention known as the Change Laboratory to illustrate how the processes of organisational change initiated at a secondary school can be applied to develop tools and practices to analyse and potentially re-make educational traditions in a bottom-up manner. In this regard it is shown how a cultural-historical activity theory (CHAT perspective can be combined with a relational approach to generate the theoretical and practical tools for managing change at a school. Referring to an ongoing research project at a school, the paper describes how teachers and management there, with the aid of the researcher, attempt to re-configure their educational praxis by drawing on past, present and future scenarios from their schooling activity. These are correlated with similarly historically evolving theoretical models and recorded empirical data using the Vygotskyian method of double stimulation employed by the Change Laboratory. A relational conceptualisation of the school’s epistemological, pedagogical and organisational traditions is used to map out the connections between various actors, resources, roles and divisions of labour at the school. In this way the research intervention proposes a model of educational change that graphically represents it as a network of mediated relationships so that its artefacts, practices and traditions can be clearly understood and effectively manipulated according to the shared objectives of the teachers and school management. Such a relationally-oriented activity theory approach has significant implications in terms of challenging conventional processes of educational transformation as well as hegemonic knowledge-making traditions themselves.

Neuromorphic optical sensor chip with color change-intensity change disambiguation

Science.gov (United States)

Fu, ZhenHong; Mao, Rui; Cartwright, Alexander N.; Titus, Albert H.

2010-02-01

In this paper, we describe the development of a novel, retina-like neuromorphic chip that has an array of two types of retina 'cells' arranged to mimic the fovea structure in certain animals. One of the two retina cell types performs irradiance detection and the other can perform color detection. Together, via the two parallel pathways the retina chip can perform color change intensity change disambiguation (CCICD). The irradiance detection cell has a wide-dynamic detection range that spans almost 3 orders of magnitude. The color detection cell has a buried double junction (BDJ) photodiode as the photoreceptor followed by two parallel logarithmic I-V convertors. The output from this is a color response which has at least a 50nm resolution for wavelengths from 400nm to 900nm. With these two cells, the array can perform color change -intensity change disambiguation (CCICD) to determine if a change in the output of the irradiance pathway is because of irradiance change, color change, or both. This biological retina-like neuromorphic sensor array is implemented in ON-SEMI 0.5μm technology, a standard CMOS fabrication process available at MOSIS.

Harper, S L; Edge, V L; Cunsolo Willox, A

2012-03-01

Global climate change and its impact on public health exemplify the challenge of managing complexity and uncertainty in health research. The Canadian North is currently experiencing dramatic shifts in climate, resulting in environmental changes which impact Inuit livelihoods, cultural practices, and health. For researchers investigating potential climate change impacts on Inuit health, it has become clear that comprehensive and meaningful research outcomes depend on taking a systemic and transdisciplinary approach that engages local citizens in project design, data collection, and analysis. While it is increasingly recognised that using approaches that embrace complexity is a necessity in public health, mobilizing such approaches from theory into practice can be challenging. In 2009, the Rigolet Inuit Community Government in Rigolet, Nunatsiavut, Canada partnered with a transdisciplinary team of researchers, health practitioners, and community storytelling facilitators to create the Changing Climate, Changing Health, Changing Stories project, aimed at developing a multi-media participatory, community-run methodological strategy to gather locally appropriate and meaningful data to explore climate-health relationships. The goal of this profile paper is to describe how an EcoHealth approach guided by principles of transdisciplinarity, community participation, and social equity was used to plan and implement this climate-health research project. An overview of the project, including project development, research methods, project outcomes to date, and challenges encountered, is presented. Though introduced in this one case study, the processes, methods, and lessons learned are broadly applicable to researchers and communities interested in implementing EcoHealth approaches in community-based research.

Lateral Attitude Change.

Glaser, Tina; Dickel, Nina; Liersch, Benjamin; Rees, Jonas; Süssenbach, Philipp; Bohner, Gerd

2015-08-01

The authors propose a framework distinguishing two types of lateral attitude change (LAC): (a) generalization effects, where attitude change toward a focal object transfers to related objects, and (b) displacement effects, where only related attitudes change but the focal attitude does not change. They bring together examples of LAC from various domains of research, outline the conditions and underlying processes of each type of LAC, and develop a theoretical framework that enables researchers to study LAC more systematically in the future. Compared with established theories of attitude change, the LAC framework focuses on lateral instead of focal attitude change and encompasses both generalization and displacement. Novel predictions and designs for studying LAC are presented. © 2014 by the Society for Personality and Social Psychology, Inc.

Chang'E-3 mission is the main task of Phase two of China Lunar Exploration Program (CLEP), and also is Chinese first probe of landing, working and roving on the moon. Chang'E-3 craft composed of a lander and a rover, and each of them carry four scientific payloads respectively. The landing site of Chang'E-3 was located at 44.12 degrees north latitude and 19.51 degrees west longitude, where is in the northern part of Imbrium Which the distance in its west direction from the landing site of former Soviet probe Luna-17 is about 400 km, and about 780km far from the landing site of Appolo-17 in its southeast direction. Unfortunately, after a series of scientific tests and exploration on the surface of the moon, the motor controller communication of the rover emerged a breakdown on January 16, 2014, which leaded the four payloads onboard the rover can't obtain data anymore. However, we have received some interesting scientific data which have been studied by Chinese scientists. During the landing process of Chang'E-3, the Landing camera got total 4673 images with the Resolution in millimeters to meters, and the lander and rover took pictures for each other at different point with Topography camera and Panoramic camera. We can find characteristic changes in celestial brightness with time by analyzing image data from Lunar-based Ultraviolet Telescope (LUT) and an unprecedented constraint on water content in the sunlit lunar exosphere seen by LUT). The figure observed by EUV camera (EUVC) shows that there is a transient weak area of the Earth's plasma sphere; This event took place about three hours. The scientists think that it might be related to the change of the particle density of mid-latitude ionosphere. The preliminary spectral and mineralogical results from the landing site are derived according to the data of Visible and Near-infrared Imaging Spectrometer (VNIS). Seven major elements including Mg, Al, Si, K, Ca, Ti and Fe have been identified by the Active Particle

Toward a Psychology of Social Change: A Typology of Social Change

Science.gov (United States)

de la Sablonnière, Roxane

2017-01-01

Millions of people worldwide are affected by dramatic social change (DSC). While sociological theory aims to understand its precipitants, the psychological consequences remain poorly understood. A large-scale literature review pointed to the desperate need for a typology of social change that might guide theory and research toward a better understanding of the psychology of social change. Over 5,000 abstracts from peer-reviewed articles were assessed from sociological and psychological publications. Based on stringent inclusion criteria, a final 325 articles were used to construct a novel, multi-level typology designed to conceptualize and categorize social change in terms of its psychological threat to psychological well-being. The typology of social change includes four social contexts: Stability, Inertia, Incremental Social Change and, finally, DSC. Four characteristics of DSC were further identified: the pace of social change, rupture to the social structure, rupture to the normative structure, and the level of threat to one's cultural identity. A theoretical model that links the characteristics of social change together and with the social contexts is also suggested. The typology of social change as well as our theoretical proposition may serve as a foundation for future investigations and increase our understanding of the psychologically adaptive mechanisms used in the wake of DSC.

Changing historical flood behaviour - is there a link to landscape changes?

Science.gov (United States)

Rogger, Magdalena; Kiss, Andrea; Bloeschl, Guenter

2014-05-01

Although large-scale changes in flood behaviour are usually related to the variability and changes of climatic conditions and atmospheric patterns, human impact clearly also played an important role in changing flood behaviour by various types of river regulations and by land use changes (vegetation cover and soil conditions). The influence of land use changes on the flood regime is, however, still poorly understood. Based on scientific literature, we present the major phases of historical landscape changes of the last 1000 years in Europe discussing possible impacts on the related flood regimes. On the one hand, we provide an overview of major landscape changes and phases of changes in Europe dividing the available evidence into four major regions (Central Europe, Mediterranean, North- and West-Europe). On the other hand, we present case studies where we discuss the potential differences in the impacts of changes in specific vegetation types or the abandonment of formerly cultivated areas (with special emphasis on hilly areas) on the flood regime. In this sense, we make a special emphasis on the LIA-MWP (Little Ice Age - Medieval Warm Period) transition (i.e. 13th-15th centuries) as well as on the period of the early industrial revolution (18th-19th centuries).

Does changing social influence engender changes in alcohol intake? A meta-analysis.

Science.gov (United States)

Prestwich, Andrew; Kellar, Ian; Conner, Mark; Lawton, Rebecca; Gardner, Peter; Turgut, Liz

2016-10-01

Past research has suggested that social influences on drinking can be manipulated with subsequent reductions in alcohol intake. However, the experimental evidence for this and the best strategies to positively change these social influences have not been meta-analyzed. This research addressed these gaps. Randomized controlled trials testing social influence-based interventions on adults' drinking were systematically reviewed and meta-analyzed. The behavior change techniques used in each study were coded and the effect sizes showing the impact of each intervention on (a) social influence and (b) alcohol intake were calculated. Metaregressions identified the association between these effect sizes, as well as the effect of specific behavior change techniques on social influences. Forty-one studies comprising 17,445 participants were included. Changes in social influences were significantly associated with changes in alcohol intake. However, even moderate-to-large changes in social influences corresponded with only a small change in drinking behavior and changing social influences did not reduce alcohol-related problems. Providing normative information about others' behavior and experiences was the most effective technique to change social influences. Social influences and normative beliefs can be changed in drinkers, particularly by providing normative information about how much others' drink. However, even generating large changes in these constructs are likely to engender only small changes in alcohol intake. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Probabilistic BPRRC: Robust Change Detection against Illumination Changes and Background Movements

Science.gov (United States)

Yokoi, Kentaro

This paper presents Probabilistic Bi-polar Radial Reach Correlation (PrBPRRC), a change detection method that is robust against illumination changes and background movements. Most of the traditional change detection methods are robust against either illumination changes or background movements; BPRRC is one of the illumination-robust change detection methods. We introduce a probabilistic background texture model into BPRRC and add the robustness against background movements including foreground invasions such as moving cars, walking people, swaying trees, and falling snow. We show the superiority of PrBPRRC in the environment with illumination changes and background movements by using three public datasets and one private dataset: ATON Highway data, Karlsruhe traffic sequence data, PETS 2007 data, and Walking-in-a-room data.

Microenvironmental change as a mechanism to study global change.

Science.gov (United States)

Lortie, C. J.

2016-12-01

Global change is a set of significant processes that influence all aspects of ecosystem functioning and often-natural services within Santa Barbara County. The sensitivity of coastal and urban systems is certainly very high. However, profound changes are also predicted for arid and semi-arid systems globally, and California is no exception. These dryland systems are less buffered by oceanic processes and typically express high inter-annual variation in precipitation and temperatures in addition to perturbations associated with long-term droughts. However, climate estimates and downscaled values can present challenges in providing evidence at the scale relevant to individual species or individuals, and the importance of biotic interactions must be coupled to these estimates in space and time. Coupled indicators of key micro-environmental measures to both positive and negative interactions between foundation species and other organisms provide a metric of buffering capacity and resilience to global change at fine spatial scales. Consequently, the primary objective of this research project is to provide both the a well-articulated, ecologically relevant micro-environmental big data measure of global change within Santa Barbara County and a coupled estimate of concurrent changes in interactions in key species within the region. Shrubs directly and indirectly buffered local changes in the microenvironment thereby functioning as refuges for other species within arid and semi-arid regions subject to dramatic global change drivers. The following major patterns were identified: (i) shrub micro-environments reduce the level of stress and amplitude of variation associated with temperature and moisture, (ii) many plant and animal species including threatened lizards are relatively more common with shrubs within the region, and (iii) the variation in the interaction patterns between species relates to the extent of amelioration provided by shrub-biodiversity complexes within

Received ideas about climatic change are a mixture of right and wrong information. The authors use these ideas as starting points to shade light on what we really know and what we believe to know. The book is divided in three main chapters: should we act in front of climatic change? How can we efficiently act? How can we equitably act? For each chapter a series of received ideas is analyzed in order to find those which can usefully contribute to mitigate the environmental, economical and social impacts of climatic change. (J.S.)

Consumers world-wide are driving changes in the agriculture and food sector. Rising consumer income, changing demographics and lifestyles, and shifting preferences due to new information about the links between diet and health all contribute to new demands for foods. At the same time, technological changes in production, processing and distribution, growth in large-scale retailing, and changes in product availability, as well as expansion of trade world wide, have contributed to a rapidly changing market for food products. Changes in seafood consumption reflect these changes. The changes in consumer consumption patterns, new technologies and trade in product offer both expanded markets as well as new challenges to consumer exposure to food-borne risks. The strict quality control requirements of retail brokers, growth of private labels, and development of value-protecting marketing channels have become increasingly important in food markets. This paper addresses major trends that affect seafood consumption and the market for seafood products and the implications of these changes for consumer risk exposure to food safety hazards. The current economic environment highlights similarities and differences between the developed and developing countries, as well as diversity worldwide in consumption of seafood. Within this context, four major trends affect consumer consumption of foods, including seafood and fish products today: rising income; changing demographics; changing markets for food; and an increasingly global market for food products. Changes in consumer risk exposure to food safety problems are addressed in the context of these trends.

International aspects of climate change: The intergovernmental panel on climate change

1990-01-01

The impact of various international conferences concerning global climate change on international opinions and attitudes is discussed. A number of conferences over the past two decades have drawn attention to the large socio-economic consequences of climate change. There has been increasing attention given to the likely affect of anthropogenically derived greenhouse gases on the global climate. Some early uncertainty over the likely long term changes in global temperature have been replaced by a scientific consensus that global temperatures are increasing and will continue to do so into the next century. Public awareness of the possibility of climate change and severe socio-economic consequences has been increasing and was given a major impetus by the Toronto Conference on the Changing Atmosphere. An estimate of the possible time to solution of the climate change issue is given as 1988-2005, a span of 17 years. The Intergovernmental Panel on Climate Change has focused work into three working groups examining science, impacts and response strategies. 28 refs., 3 figs., 6 tabs

Changing micronutrient intake through (voluntary) behaviour change. The case of folate.

Jensen, Birger B; Lähteenmäki, Liisa; Grunert, Klaus G; Brown, Kerry A; Timotijevic, Lada; Barnett, Julie; Shepherd, Richard; Raats, Monique M

2012-06-01

The objective of this study was to relate behaviour change mechanisms to nutritionally relevant behaviour and demonstrate how the different mechanisms can affect attempts to change these behaviours. Folate was used as an example to illuminate the possibilities and challenges in inducing behaviour change. The behaviours affecting folate intake were recognised and categorised. Behaviour change mechanisms from "rational model of man", behavioural economics, health psychology and social psychology were identified and aligned against folate-related behaviours. The folate example demonstrated the complexity of mechanisms influencing possible behavioural changes, even though this only targets the intake of a single micronutrient. When considering possible options to promote folate intake, the feasibility of producing the desired outcome should be related to the mechanisms of required changes in behaviour and the possible alternatives that require no or only minor changes in behaviour. Dissecting the theories provides new approaches to food-related behaviour that will aid the development of batteries of policy options when targeting nutritional problems.

FUNDAMENTALS OF CHANGE MANAGEMENT

Directory of Open Access Journals (Sweden)

Alexandra Patricia Braica

2013-12-01

Full Text Available To understand the mechanisms of change within an organization, as well as those of innovation, one must consider the constructed character of change. Change is not a natural phenomenon, it is an issue that requires research. However, change should not be understood as a crisis, or even as a mere process of adaptation or development, but rather as a manifestation of a multitude of mutations within institutions. The main subject of study in change management is organization. The exercise of management functions in processes of change comprises diverse activities starting at the moment of realizing the need for change, and up until the moment of transformations imposed by the implementation of these changes.

Planned change or emergent change implementation approach and nurses' professional clinical autonomy.

Luiking, Marie-Louise; Aarts, Leon; Bras, Leo; Grypdonck, Maria; van Linge, Roland

2017-11-01

Nurses' clinical autonomy is considered important for patients' outcome and influenced by the implementation approach of innovations. Emergent change approach with participation in the implementation process is thought to increase clinical autonomy. Planned change approach without this participation is thought not to increase clinical autonomy. Evidence of these effects on clinical autonomy is however limited. To examine the changes in clinical autonomy and in personal norms and values for a planned change and emergent change implementation of an innovation, e.g. intensive insulin therapy. Prospective comparative study with two geographically separated nurses' teams on one intensive care unit (ICU), randomly assigned to the experimental conditions. Data were collected from March 2008 to January 2009. Pre-existing differences in perception of team and innovation characteristics were excluded using instruments based on the innovation contingency model. The Nursing Activity Scale was used to measure clinical autonomy. The Personal Values and Norms instrument was used to assess orientation towards nursing activities and the Team Learning Processes instrument to assess learning as a team. Pre-implementation the measurements did not differ. Post-implementation, clinical autonomy was increased in the emergent change team and decreased in the planned change team. The Personal Values and Norms instrument showed in the emergent change team a decreased hierarchic score and increased developmental and rational scores. In the planned change team the hierarchical and group scores were increased. Learning as a team did not differ between the teams. In both teams there was a change in clinical autonomy and orientation towards nursing activities, in line with the experimental conditions. Emergent change implementation resulted in more clinical autonomy than planned change implementation. If an innovation requires the nurses to make their own clinical decisions, an emergent change

Change Blindness in Pigeons (Columba livia: the Effects of Change Salience and Timing

Directory of Open Access Journals (Sweden)

Walter Troy Herbranson

2015-08-01

Full Text Available Change blindness is a well-established phenomenon in humans, in which plainly visible changes in the environment go unnoticed. Recently a parallel change blindness phenomenon has been demonstrated in pigeons. The reported experiment follows up on this finding by investigating whether change salience affects change blindness in pigeons the same way it affects change blindness in humans. Birds viewed alternating displays of randomly generated lines back-projected onto three response keys, with one or more line features on a single key differing between consecutive displays. Change salience was manipulated by varying the number of line features that changed on the critical response key. Results indicated that change blindness is reduced if a change is made more salient, and this matches previous human results. Furthermore, accuracy patterns indicate that pigeons’ effective search area expanded over the course of a trial to encompass a larger portion of the stimulus environment. Thus, the data indicate two important aspects of temporal cognition. First, the timing of a change has a profound influence on whether or not that change will be perceived. Second, pigeons appear to engage in a serial search for changes, in which additional time is required to search additional locations.

Climatic change is gaining ground and with no doubt is stimulated by human activities. It is therefore urgent to better understand its nature, importance and potential impacts. The chapters of this book have been written by US and French experts of the global warming question. After a description of the Intergovernmental Panel on Climate Change (IPCC, GIEC in French) consensus, they present the past and present researches on each of the main component of the climate system, on the question of climatic change impacts and on the possible answers. The conclusion summarizes the results of each chapter. Content: presentation of the IPCC; greenhouse effect, radiation balance and clouds; atmospheric aerosols and climatic change; global water cycle and climate; influence of climatic change on the continental hydrologic cycle; ocean and climate; ice and climate; global carbon cycle; about some impacts of climatic change on Europe and the Atlantic Ocean; interaction between atmospheric chemistry and climate; climate and society, the human dimension.

Global change and marine communities: Alien species and climate change

International Nuclear Information System (INIS)

Occhipinti-Ambrogi, Anna

2007-01-01

Anthropogenic influences on the biosphere since the advent of the industrial age are increasingly causing global changes. Climatic change and the rising concentration of greenhouse gases in the atmosphere are ranking high in scientific and public agendas, and other components of global change are also frequently addressed, among which are the introductions of non indigenous species (NIS) in biogeographic regions well separated from the donor region, often followed by spectacular invasions. In the marine environment, both climatic change and spread of alien species have been studied extensively; this review is aimed at examining the main responses of ecosystems to climatic change, taking into account the increasing importance of biological invasions. Some general principles on NIS introductions in the marine environment are recalled, such as the importance of propagule pressure and of development stages during the time course of an invasion. Climatic change is known to affect many ecological properties; it interacts also with NIS in many possible ways. Direct (proximate) effects on individuals and populations of altered physical-chemical conditions are distinguished from indirect effects on emergent properties (species distribution, diversity, and production). Climatically driven changes may affect both local dispersal mechanisms, due to the alteration of current patterns, and competitive interactions between NIS and native species, due to the onset of new thermal optima and/or different carbonate chemistry. As well as latitudinal range expansions of species correlated with changing temperature conditions, and effects on species richness and the correlated extinction of native species, some invasions may provoke multiple effects which involve overall ecosystem functioning (material flow between trophic groups, primary production, relative extent of organic material decomposition, extent of benthic-pelagic coupling). Some examples are given, including a special

"In this paper I use microdata from the [U.S.] Panel Study of Income Dynamics to measure the financial returns to intercounty and interstate migration for individuals in a temporal framework accounting for gains that accrue over time.... To account for the indirect effects of migration on earnings, explanatory variables are created by interacting migration status with: (1) occupational change, (2) employer change and (3) changes in both occupation and employer. These interaction terms are then included in the earnings functions. Earnings are estimated for three years subsequent to the migration decision to account for the financial returns to migration accruing over time. Results indicate that, when estimating earnings, the use of a simple migration dummy variable will mask the indirect effects of migration on earnings." excerpt

Changes to Watershed Hydrology due to Changing Snowmelt Patterns, Michigan, US

Ford, C.; Kendall, A. D.; Hyndman, D. W.

2017-12-01

With increasing temperatures and changing precipitation patterns associated with global climate change, the future of hydrologic resources related to snowmelt is less certain than ever. Most existing snowmelt hydrology research focuses on mountainous regions such as the western United States, where snowpack is a primary reservoir of available freshwater. Less research has been done on snowmelt hydrology in non-mountainous, temperate middle to upper latitude regions such as the Midwestern US, where snowmelt is still an important contributor to water budgets (and critically summer water supplies). This study examines the changes to watershed hydrology due to changing snowmelt patterns in Michigan, which has a tension line between seasonally-persistent snowpacks in the north, and episodic snowpacks in the south. This transition varies in space and time, and is likely moving northward as a consequence of climate change. Changes to snow and winter weather were statistically determined from output of the NOAA's Snow Data Assimilation System (SNODAS) model along with historical weather data from the Global Historical Climatology Network. Stream data from the USGS, combined with in-house monitoring data from groundwater and soil moisture networks provide insight into the hydrologic changes. Snowmelt in years with warmer winter temperatures tend to end earlier in the year, resulting in earlier peak stream flows. These changes become more noticeable in the northern regions of the state, where snowfall amounts can be amongst the largest in the country. This study also examines the changing spatial transition zone between regions with snow lasting throughout the season and regions with a more episodic snow presence. In an area with some of the largest freshwater resources in the world, significant changes to streamflow and groundwater recharge could impact already stressed ecosystems and local water supplies.

Changing an undergraduate medical curriculum is a recurring, high-stakes undertaking at medical schools. This study aimed to explore how people leading major curriculum changes conceived of the process of enacting change and the strategies they relied on to succeed in their efforts. The first author individually interviewed nine leaders who were leading or had led the most recent undergraduate curriculum change in one of the eight medical schools in the Netherlands. Interviews were between December 2015 and April 2016, using a semi-structured interview format. Data analysis occurred concurrently with data collection, with themes being constructed inductively from the data. Leaders conceived of curriculum change as a dynamic, complex process. They described three major challenges they had to deal with while navigating this process: the large number of stakeholders championing a multitude of perspectives, dealing with resistance, and steering the change process. Additionally, strategies for addressing these challenges were described. The authors identified an underlying principle informing the work of these leaders: being and remaining aware of emerging situations, and carefully constructing strategies for ensuring the intended outcomes were reached and contributed to the progress of the change process. This empirical, descriptive study enriches the understanding of how institutional leaders navigate the complexities of major medical curriculum changes. The insights serve as a foundation for training and coaching future change leaders. To broaden the understanding of curriculum change processes, future studies could investigate the processes through alternative stakeholder perspectives.Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a "work of the United States Government" for which copyright protection under Title 17 of the United States Code is not available.

Neural correlates of change detection and change blindness in a working memory task.

Science.gov (United States)

Pessoa, Luiz; Ungerleider, Leslie G

2004-05-01

Detecting changes in an ever-changing environment is highly advantageous, and this ability may be critical for survival. In the present study, we investigated the neural substrates of change detection in the context of a visual working memory task. Subjects maintained a sample visual stimulus in short-term memory for 6 s, and were asked to indicate whether a subsequent, test stimulus matched or did not match the original sample. To study change detection largely uncontaminated by attentional state, we compared correct change and correct no-change trials at test. Our results revealed that correctly detecting a change was associated with activation of a network comprising parietal and frontal brain regions, as well as activation of the pulvinar, cerebellum, and inferior temporal gyrus. Moreover, incorrectly reporting a change when none occurred led to a very similar pattern of activations. Finally, few regions were differentially activated by trials in which a change occurred but subjects failed to detect it (change blindness). Thus, brain activation was correlated with a subject's report of a change, instead of correlated with the physical change per se. We propose that frontal and parietal regions, possibly assisted by the cerebellum and the pulvinar, might be involved in controlling the deployment of attention to the location of a change, thereby allowing further processing of the visual stimulus. Visual processing areas, such as the inferior temporal gyrus, may be the recipients of top-down feedback from fronto-parietal regions that control the reactive deployment of attention, and thus exhibit increased activation when a change is reported (irrespective of whether it occurred or not). Whereas reporting that a change occurred, be it correctly or incorrectly, was associated with strong activation in fronto-parietal sites, change blindness appears to involve very limited territories.

Changes in Dimethyl Sulfide Oceanic Distribution due to Climate Change

Energy Technology Data Exchange (ETDEWEB)

Cameron-Smith, P; Elliott, S; Maltrud, M; Erickson, D; Wingenter, O

2011-02-16

Dimethyl sulfide (DMS) is one of the major precursors for aerosols and cloud condensation nuclei in the marine boundary layer over much of the remote ocean. Here they report on coupled climate simulations with a state-of-the-art global ocean biogeochemical model for DMS distribution and fluxes using present-day and future atmospheric CO{sub 2} concentrations. They find changes in zonal averaged DMS flux to the atmosphere of over 150% in the Southern Ocean. This is due to concurrent sea ice changes and ocean ecosystem composition shifts caused by changes in temperature, mixing, nutrient, and light regimes. The largest changes occur in a region already sensitive to climate change, so any resultant local CLAW/Gaia feedback of DMS on clouds, and thus radiative forcing, will be particularly important. A comparison of these results to prior studies shows that increasing model complexity is associted with reduced DMS emissions at the equator and increased emissions at high latitudes.

The changing world of climate change: Oregon leads the states

Following on the heels of recent national and international developments in climate change policy, Oregon's open-quote best-of-batch close-quote proceeding has validated the use of CO 2 offsets as a cost-effective means of advancing climate change mitigation goals. The proceeding was a first in several respects and represents a record commitment of funds to CO 2 mitigation by a private entity. In December 1995, the Intergovernmental Panel on Climate Change (IPCC), issued its Second Assessment Report. The IPCC's conclusion that open-quotes[t]he balance of evidence suggests a discernible human influence on global climateclose quotes fundamentally changed the tenor of the policy debate regarding potential threats associated with global climate change. At the Climate Change Convention's Conference of the Parties (COP) in Geneva in July 1996, most countries, including the United States, advocated adopting the IPCC report as the basis for swift policy movement toward binding international emissions targets. The next COP, in December 1997, is scheduled to be the venue for the signing of a treaty protocol incorporating such targets. Binding targets would have major consequences for power plant operators in the US and around the world. Recent developments in the state of Oregon show the kinds of measures that may become commonplace at the state level in addressing climate change mitigation. First, Oregon recently completed the first administrative proceeding in the US aimed at offsetting the greenhouse gas emissions of a new power plant. Second, a legislatively mandated energy facility siting task force recently recommended that Oregon adopt a carbon dioxide (CO 2 ) standard for new power plant construction and drop use of the open-quotes need for powerclose quotes standard. This article reviews these two policy milestones and their implications for climate change mitigation in the United States

Moving communities toward policy change: APPEAL's 4-prong policy change model.

Science.gov (United States)

Tong, Elisa K; Lew, Rod

2013-09-01

Policy change is recognized for underlying much of the success of tobacco control. However, there is little evidence and attention on how Asian American and Native Hawaiian and Pacific Islander (AA and NHPI) communities may engage in policy change. Challenges for AA and NHPI communities include the racial/ethnic and geographic diversity, and tobacco data accurately representing the communities. Over the past decade, the Asian Pacific Partners for Empowerment, Advocacy and Leadership (APPEAL) has worked to develop and implement policy change for AA and NHPI communities. This article describes APPEAL's 4-prong policy change model, in the context of its overall strategic framework for policy change with communities that accounts for varying levels of readiness and leadership capacity, and targets four different levels of policy change (community, mainstream institution, legislative, and corporate). The health promotion implication of this framework for tobacco control policy engagement is for improving understanding of effective pathways to policy change, promoting innovative methods for policy analysis, and translating them into effective implementation and sustainability of policy initiatives. The APPEAL strategic framework can transcend into other communities and health topics that ultimately may contribute to the elimination of health disparities.

"You've Changed": Low Self-Concept Clarity Predicts Lack of Support for Partner Change.

Science.gov (United States)

Emery, Lydia F; Gardner, Wendi L; Finkel, Eli J; Carswell, Kathleen L

2018-03-01

People often pursue self-change, and having a romantic partner who supports these changes increases relationship satisfaction. However, most existing research focuses only on the experience of the person who is changing. What predicts whether people support their partner's change? People with low self-concept clarity resist self-change, so we hypothesized that they would be unsupportive of their partner's changes. People with low self-concept clarity did not support their partner's change (Study 1a), because they thought they would have to change, too (Study 1b). Low self-concept clarity predicted failing to support a partner's change, but not vice versa (Studies 2 and 3), and only for larger changes (Study 3). Not supporting a partner's change predicted decreases in relationship quality for both members of the couple (Studies 2 and 3). This research underscores the role of partners in self-change, suggesting that failing to support a partner's change may stem from self-concept confusion.

Visual long-term memory and change blindness: Different effects of pre- and post-change information on one-shot change detection using meaningless geometric objects.

Science.gov (United States)

Nishiyama, Megumi; Kawaguchi, Jun

2014-11-01

To clarify the relationship between visual long-term memory (VLTM) and online visual processing, we investigated whether and how VLTM involuntarily affects the performance of a one-shot change detection task using images consisting of six meaningless geometric objects. In the study phase, participants observed pre-change (Experiment 1), post-change (Experiment 2), or both pre- and post-change (Experiment 3) images appearing in the subsequent change detection phase. In the change detection phase, one object always changed between pre- and post-change images and participants reported which object was changed. Results showed that VLTM of pre-change images enhanced the performance of change detection, while that of post-change images decreased accuracy. Prior exposure to both pre- and post-change images did not influence performance. These results indicate that pre-change information plays an important role in change detection, and that information in VLTM related to the current task does not always have a positive effect on performance.

Detecting changes, in performance, sales, markets, risks, social relations, or public opinions, constitutes an important adaptive function. In a sequential paradigm devised to investigate detection of change, every trial provides a sample of binary outcomes (e.g., correct vs. incorrect student responses). Participants have to decide whether the proportion of a focal feature (e.g., correct responses) in the population from which the sample is drawn has decreased, remained constant, or increased. Strong and persistent anomalies in change detection arise when changes in proportional quantities vary orthogonally to changes in absolute sample size. Proportional increases are readily detected and nonchanges are erroneously perceived as increases when absolute sample size increases. Conversely, decreasing sample size facilitates the correct detection of proportional decreases and the erroneous perception of nonchanges as decreases. These anomalies are however confined to experienced samples of elementary raw events from which proportions have to be inferred inductively. They disappear when sample proportions are described as percentages in a normalized probability format. To explain these challenging findings, it is essential to understand the inductive-learning constraints imposed on decisions from experience.

Human-experienced temperature changes exceed global average climate changes for all income groups

Global climate change alters local climates everywhere. Many climate change impacts, such as those affecting health, agriculture and labor productivity, depend on these local climatic changes, not global mean change. Traditional, spatially averaged climate change estimates are strongly influenced by the response of icecaps and oceans, providing limited information on human-experienced climatic changes. If used improperly by decision-makers, these estimates distort estimated costs of climate change. We overlay the IPCC’s 20 GCM simulations on the global population distribution to estimate local climatic changes experienced by the world population in the 21st century. The A1B scenario leads to a well-known rise in global average surface temperature of +2.0°C between the periods 2011-2030 and 2080-2099. Projected on the global population distribution in 2000, the median human will experience an annual average rise of +2.3°C (4.1°F) and the average human will experience a rise of +2.4°C (4.3°F). Less than 1% of the population will experience changes smaller than +1.0°C (1.8°F), while 25% and 10% of the population will experience changes greater than +2.9°C (5.2°F) and +3.5°C (6.2°F) respectively. 67% of the world population experiences temperature changes greater than the area-weighted average change of +2.0°C (3.6°F). Using two approaches to characterize the spatial distribution of income, we show that the wealthiest, middle and poorest thirds of the global population experience similar changes, with no group dominating the global average. Calculations for precipitation indicate that there is little change in average precipitation, but redistributions of precipitation occur in all income groups. These results suggest that economists and policy-makers using spatially averaged estimates of climate change to approximate local changes will systematically and significantly underestimate the impacts of climate change on the 21st century population.

Assessment of Change in Psychoanalysis: Another Way of Using the Change After Psychotherapy Scales.

Science.gov (United States)

Pires, António Pazo; Gonçalves, João; Sá, Vânia; Silva, Andrea; Sandell, Rolf

2016-04-01

A systematic method is presented whereby material from a full course of psychoanalytic treatment is analyzed to assess changes and identify patterns of change. Through an analysis of session notes, changes were assessed using the CHange After Psychotherapy scales (CHAP; Sandell 1987a), which evaluate changes in five rating variables (symptoms, adaptive capacity, insight, basic conflicts, and extratherapeutic factors). Change incidents were identified in nearly every session. Early in the analysis, relatively more change incidents related to insight were found than were found for the other types of change. By contrast, in the third year and part of the fourth year, relatively more change incidents related to basic conflicts and adaptive capacity were found. While changes related to symptoms occurred throughout the course of treatment, such changes were never more frequent than other types of change. A content analysis of the change incidents allowed a determination of when in the treatment the patient's main conflicts (identified clinically) were overcome. A crossing of quantitative data with clinical and qualitative data allowed a better understanding of the patterns of change. © 2016 by the American Psychoanalytic Association.

Simulation of Land-Cover Change in Taipei Metropolitan Area under Climate Change Impact

International Nuclear Information System (INIS)

Huang, Kuo-Ching; Huang, Thomas C C

2014-01-01

Climate change causes environment change and shows up on land covers. Through observing the change of land use, researchers can find out the trend and potential mechanism of the land cover change. Effective adaptation policies can affect pattern of land cover change and may decrease the risks of climate change impacts. By simulating land use dynamics with scenario settings, this paper attempts to explore the relationship between climate change and land-cover change through efficient adaptation polices. It involves spatial statistical model in estimating possibility of land-cover change, cellular automata model in modeling land-cover dynamics, and scenario analysis in response to adaptation polices. The results show that, without any control, the critical eco-areas, such as estuarine areas, will be destroyed and people may move to the vulnerable and important economic development areas. In the other hand, under the limited development condition for adaptation, people migration to peri-urban and critical eco-areas may be deterred

Climate for Change: Non-State Actors and the Global Politics of the Greenhouse provides a challenging explanation of the forces that have shaped the international global warming debate. Unlike existing books on the politics of climate change, this book concentrates on how non-stage actors, such as scientific, environmental and industry groups, as opposed to governmental organisations, affect political outcomes in global fora on climate change. It also provides insights in to the role of the media in influencing the agenda. The book draws on a range of analytical approaches to assess and explain the influence of these non-governmental organisations in the course of global climate change politics. The book will be of interest to all researchers and policy-makers associated with climate change, and will be used on university courses in international relations, politics and environmental studies.

[The history of facial paralysis].

Science.gov (United States)

Glicenstein, J

2015-10-01

Facial paralysis has been a recognized condition since Antiquity, and was mentionned by Hippocratus. In the 17th century, in 1687, the Dutch physician Stalpart Van der Wiel rendered a detailed observation. It was, however, Charles Bell who, in 1821, provided the description that specified the role of the facial nerve. Facial nerve surgery began at the end of the 19th century. Three different techniques were used successively: nerve anastomosis, (XI-VII Balance 1895, XII-VII, Korte 1903), myoplasties (Lexer 1908), and suspensions (Stein 1913). Bunnell successfully accomplished the first direct facial nerve repair in the temporal bone, in 1927, and in 1932 Balance and Duel experimented with nerve grafts. Thanks to progress in microsurgical techniques, the first faciofacial anastomosis was realized in 1970 (Smith, Scaramella), and an account of the first microneurovascular muscle transfer published in 1976 by Harii. Treatment of the eyelid paralysis was at the origin of numerous operations beginning in the 1960s; including palpebral spring (Morel Fatio 1962) silicone sling (Arion 1972), upperlid loading with gold plate (Illig 1968), magnets (Muhlbauer 1973) and transfacial nerve grafts (Anderl 1973). By the end of the 20th century, surgeons had at their disposal a wide range of valid techniques for facial nerve surgery, including modernized versions of older techniques.

Co istotne, nie potwierdzają się wcześniejsze opinie o znacznej hepatotoksyczności leku. Rezultaty badań kontrolowanych niemal jednoznacznie wskazują, że pod względem skuteczności i bezpieczeństwa agomelatyna nie ustępuje lekom przeciwdepresyjnym z grupy selektywnych inhibitorów wychwytu zwrotnego serotoniny. Przeprowadzone w ostatnich latach badania dotyczące wpływu agomelatyny na anhedonię mają charakter badań otwartych, agomelatyna nie była w nich porównywana z innymi lekami przeciwdepresyjnymi, stąd też trudno jednoznacznie zinterpretować uzyskane wyniki.

Changing climate, changing forests: the impacts of climate change on forests of the northeastern United States and eastern Canada

Decades of study on climatic change and its direct and indirect effects on forest ecosystems provide important insights for forest science, management, and policy. A synthesis of recent research from the northeastern United States and eastern Canada shows that the climate of the region has become warmer and wetter over the past 100 years and that there are more extreme precipitation events. Greater change is projected in the future. The amount of projected future change depends on the emissions scenarios used. Tree species composition of northeast forests has shifted slowly in response to climate for thousands of years. However, current human-accelerated climate change is much more rapid and it is unclear how forests will respond to large changes in suitable habitat. Projections indicate significant declines in suitable habitat for spruce-fir forests and expansion of suitable habitat for oak-dominated forests. Productivity gains that might result from extended growing seasons and carbon dioxide and nitrogen fertilization may be offset by productivity losses associated with the disruption of species assemblages and concurrent stresses associated with potential increases in atmospheric deposition of pollutants, forest fragmentation, and nuisance species. Investigations of links to water and nutrient cycling suggest that changes in evapotranspiration, soil respiration, and mineralization rates could result in significant alterations of key ecosystem processes. Climate change affects the distribution and abundance of many wildlife species in the region through changes in habitat, food availability, thermal tolerances, species interactions such as competition, and susceptibility to parasites and disease. Birds are the most studied northeastern taxa. Twenty-seven of the 38 bird species for which we have adequate long-term records have expanded their ranges predominantly in a northward direction. There is some evidence to suggest that novel species, including pests and

The signature of undetected change: an exploratory electrotomographic investigation of gradual change blindness.

Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, "mudsplashes"), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected changes was contrasted with activity linked to their absence using standardized low-resolution brain electromagnetic tomography (sLORETA). Although an insufficient number of detections were present to allow for analysis of actual change detection, increased beta-2 activity in the right inferior parietal lobule (rIPL), a region repeatedly associated with change blindness in disruption paradigms, followed by increased theta activity in the right superior temporal gyrus (rSTG) was noted in undetected visual change responses relative to the absence of change. We propose the rIPL beta-2 activity to be associated with orienting attention toward visual changes, with the subsequent rise in rSTG theta activity being potentially linked with updating preconscious perceptual memory representations. NEW & NOTEWORTHY This study represents the first neuroimaging-based investigation of gradual change blindness, a visual phenomenon that has significant potential to shed light on the processes underlying visual detection and conscious perception. The use of gradual change materials is reflective of real-world visual phenomena and allows for cleaner isolation of signals associated with the neural registration of change relative to the

Global vs climate change

The various agents of global change that will affect the state of natural resources 50-100 years from now are discussed. These include economic and population growth, technological progress, and climatic change. The importance of climatic change lies in its effects on natural resources and on human activities that depend on those resources. Other factors affecting those resources include the demand on those resources from an increasing population and from a growing economy, and a more efficient use of those resources that comes from technological changes and from the consequences of economic growth itself. It is shown that there is a considerable ability to adapt to climatic change, since humans already have an intrinsic ability to adapt to the wide variations in climates that already exist and since technological developments can make it easier to cope with climatic variability. It appears that agents other than climatic change are more significant to the future state of natural resources than climatic change. Criteria for selecting options for addressing climatic change are outlined. Technological change and economic growth are seen to be key response options, since the vulnerability to climatic change depends on economic resources and technological progress. Specific options to stimulate sustainable economic growth and technological progress are listed. 16 refs., 1 fig., 2 tabs

Widespread climate change in the Himalayas and associated changes in local ecosystems.

2012-01-01

Climate change in the Himalayas, a biodiversity hotspot, home of many sacred landscapes, and the source of eight largest rivers of Asia, is likely to impact the well-being of ~20% of humanity. However, despite the extraordinary environmental, cultural, and socio-economic importance of the Himalayas, and despite their rapidly increasing ecological degradation, not much is known about actual changes in the two most critical climatic variables: temperature and rainfall. Nor do we know how changes in these parameters might impact the ecosystems including vegetation phenology. By analyzing temperature and rainfall data, and NDVI (Normalized Difference Vegetation Index) values from remotely sensed imagery, we report significant changes in temperature, rainfall, and vegetation phenology across the Himalayas between 1982 and 2006. The average annual mean temperature during the 25 year period has increased by 1.5 °C with an average increase of 0.06 °C yr(-1). The average annual precipitation has increased by 163 mm or 6.52 mmyr(-1). Since changes in temperature and precipitation are immediately manifested as changes in phenology of local ecosystems, we examined phenological changes in all major ecoregions. The average start of the growing season (SOS) seems to have advanced by 4.7 days or 0.19 days yr(-1) and the length of growing season (LOS) appears to have advanced by 4.7 days or 0.19 days yr(-1), but there has been no change in the end of the growing season (EOS). There is considerable spatial and seasonal variation in changes in climate and phenological parameters. This is the first time that large scale climatic and phenological changes at the landscape level have been documented for the Himalayas. The rate of warming in the Himalayas is greater than the global average, confirming that the Himalayas are among the regions most vulnerable to climate change.

Identification during imposed change: the roles of personal values, type of change, and anxiety.

Sverdlik, Noga; Oreg, Shaul

2015-06-01

Using a person-situation perspective, we explain what happens to individuals' identification with a collective in the context of a change. We propose that given the anxiety that often emerges during change, individuals' personal values (conservation and openness to change) interact with type of change (imposed vs. voluntary) in predicting identification following change. In a pilot, longitudinal field study (N = 61, 67% female) of an imposed university campus relocation, we measured employees' values and identification with the university before and several months after the relocation. In two lab experiments (Study 1: N = 104, 91.3% female; Study 2: N = 113, 75.2% female), we manipulated a change to be either imposed or voluntary and compared the relationships between values and identification across types of change. In Study 2, we also measured anxiety from the change. When change was imposed (all three studies), but not when voluntary (Studies 1 and 2), individuals' conservation was positively, and openness negatively, related to individuals' post-change identification. The effects emerged only for individuals who experienced change-related anxiety (Study 2). Our findings demonstrate that individuals' identification with a changing collective depends on the amount of anxiety change elicits and on the particular combination of their values and type of change. © 2014 Wiley Periodicals, Inc.

This paper presented indicators of climate change for British Columbia (BC) with an emphasis on the coastal region. An overview of global effects of climate change was presented, as well as details of BC's current climate change action plan. Indicators examined in the paper for the BC coastal region included long-term trends in air temperature; long-term trends in precipitation; coastal ocean temperatures; sea levels on the BC coast; and the sensitivity of the BC coast to sea level rise and erosion. Data suggested that average air temperatures have become higher in many areas, and that Springtime temperatures have become warmer over the whole province. Winters have become drier in many areas of the province. Sea surface temperature has risen over the entire coast, with the North Coast and central Strait of Georgia showing the largest increases. Deep-water temperatures have also increased in 5 inlets on the South Coast. Results suggested that the direction and spatial pattern of the climate changes reported for British Columbia are consistent with broader trends in North America and the type of changes predicted by climate models for the region. Climate change will likely result in reduced snow-pack in southern BC. An earlier spring freshet on many snow-dominated river systems is anticipated as well as glacial retreat and disappearance. Warmer temperatures in some lakes and rivers are expected, as well as the increased frequency and severity of natural disturbances such as the pine mountain beetle. Large-scale shifts in ecosystems and the loss of certain ecosystems may also occur. BC's current climate plan includes cost effective actions that address GHG emissions and support efficient infrastructure and opportunities for innovation. Management programs for forest and agricultural lands have been initiated, as well as programs to reduce emissions from government operations. Research is also being conducted to understand the impacts of climate change on water

Land cover is the biophysical material on the surface of the earth. Land-cover types include grass, shrubs, trees, barren, water, and man-made features. Land cover changes continuously.  The rate of change can be either dramatic and abrupt, such as the changes caused by logging, hurricanes and fire, or subtle and gradual, such as regeneration of forests and damage caused by insects (Verbesselt et al., 2001).  Previous studies have shown that land cover has changed dramatically during the past sevearal centuries and that these changes have severely affected our ecosystems (Foody, 2010; Lambin et al., 2001). Lambin and Strahlers (1994b) summarized five types of cause for land-cover changes: (1) long-term natural changes in climate conditions, (2) geomorphological and ecological processes, (3) human-induced alterations of vegetation cover and landscapes, (4) interannual climate variability, and (5) human-induced greenhouse effect.  Tools and techniques are needed to detect, describe, and predict these changes to facilitate sustainable management of natural resources.

Climate change is a cause for concern both globally and locally. In order for it to be tackled holistically, its governance is an important topic needing scientific and practical consideration. Climate change governance is an emerging area, and one which is closely related to state and public administrative systems and the behaviour of private actors, including the business sector, as well as the civil society and non-governmental organisations. Questions of climate change governance deal both with mitigation and adaptation whilst at the same time trying to devise effective ways of managing the consequences of these measures across the different sectors. Many books have been produced on general matters related to climate change, such as climate modelling, temperature variations, sea level rise, but, to date, very few publications have addressed the political, economic and social elements of climate change and their links with governance. This book will address this gap. Furthermore, a particular feature of this book is that it not only presents different perspectives on climate change governance, but it also introduces theoretical approaches and brings these together with practical examples which show how main principles may be implemented in practice.

Change Agent – A Force Generating Resistance To Change Within An Organization?

Full Text Available The purpose of this research is to identify if the change agent represents or not a force generating resistance to change within an organization. The employees affected by a change process are usually the ones who oppose to new implementations. Their opposition is bigger or smaller, depending on the extent that they are affected and also by the direction, either positive or negative. However, employee’s opposition can be potentiated or reduced, depending on the manifestation of the following forces within an organization: communications, the type of organizational structure, management style and organizational culture, forces which refer to the organizational climate. To answer our question, we have researched the current literature and discovered that the change agent can represent a force generating resistance to change within an organization in those situations when he or she identifies with a middle or top manager from the organizational pyramid. This information is valuable to researchers and practitioners, as for a long time, employees were considered the only ones manifesting resistance, the possibility that the change agent can oppose new changes being ignored.

The data is collected from Polish and Slovene. The basic methodological device is a paraphrase which obligatorily includes an adjective. Special attention is paid to operator verbs, which often have their own semantic features. Some of them are verbs of transfer, others – verbs of motion. In most cases, however, they are causatives which denote change of features. Apart from the basic causative category, the material is classified according to its semantic features, including especially inchoativeness, terminativeness and restorativeness. In conclusion it is emphasized that analytic causatives show their semantic parameters more explicitly than is the case with verbal units and that they demonstrate considerable semantic condensity.   Z problematyki polskich i słoweńskich analityzmów kauzatywnych z parafrazą przymiotnikową Artykuł dotyczy analitycznych realizacji predykatu kauzatywnego.

Quality Climate Change Professional Development Translates into Quality Climate Change Education (Invited)

Holzer, M. A.

2013-12-01

Perhaps one of the reasons we have so many climate change deniers in the United States is that to them climate change is not occurring. This is a valid claim about climate change deniers considering that the effects of climate change in the mid-latitudes are quite subtle as compared to those found in low-latitude and high-latitude regions. A mid-latitude classroom teacher is saddled with the challenge of enlightening students about our changing climate and empowering students to assist in making necessary lifestyle changes, all the while the students don't understand the urgency in doing so. Quality climate change data and resources from the Polar Regions and low latitudes, as well as connections to researchers from these regions help to bridge the understanding of our changing climate from the extreme latitudes to the mid-latitudes. Connecting science teachers with data, resources, and researchers is one way of ensuring our mid-latitude students understand the urgency in taking appropriate actions to adapt, mitigate, and show resilience. This presentation will highlight a few of the many impacts of an authentic research experience for teachers that not only provides teachers with data, resources, and researchers, but changes the way a science teacher teaches where the methods they use mirror the methods used by scientists. National projects like PolarTREC connect educators with the science of climate change as well as the reality of impacts of climate change. For example, research expeditions in the Arctic and in Antarctica connect teachers with the content and practices of climate change science preparing them to replicate their experiences with their students. A PolarTREC experience does not end with the close of the expedition. Teachers continue their connections with the program through their educator network, the integration of PolarTREC resources into their curriculums, and communications with their principal investigators either virtually or with school

Hydrological Responses to Land-Use Change Scenarios under Constant and Changed Climatic Conditions.

Zhang, Ling; Nan, Zhuotong; Yu, Wenjun; Ge, Yingchun

2016-02-01

This study quantified the hydrological responses to land-use change scenarios in the upper and middle Heihe River basin (HRB), northwest China, under constant and changed climatic conditions by combining a land-use/cover change model (dynamic conversion of land use and its effects, Dyna-CLUE) and a hydrological model (soil and water assessment tool, SWAT). Five land-use change scenarios, i.e., historical trend (HT), ecological protection (EP), strict ecological protection (SEP), economic development (ED), and rapid economic development (RED) scenarios, were established. Under constant climatic condition, hydrological variations are only induced by land-use changes in different scenarios. The changes in mean streamflow at the outlets of the upper and the middle HRB are not pronounced, although the different scenarios produce different outcomes. However, more pronounced changes are observed on a subbasin level. The frequency of extreme flood is projected to decrease under the SEP scenario, while under the other scenarios, no changes can be found. Two emission scenarios (A1B and B1) of three general circulation models (HadCM3, CGCM3, and CCSM3) were employed to generate future possible climatic conditions. Under changed climatic condition, hydrological variations are induced by the combination of land-use and climatic changes. The results indicate that the impacts of land-use changes become secondary when the changed climatic conditions have been considered. The frequencies of extreme flood and drought are projected to decrease and increase, respectively, under all climate scenarios. Although some agreements can be reached, pronounced difference of hydrological responses can be observed for different climate scenarios of different GCMs.

Full Text Available In the 21st century all organizations have to cope with challenges caused by trigger events in the environment. The key to organizational success is how fast and efficiently they are able to react. In 2014 we conducted a research survey on this topic with the contribution of Hungarian students on Bachelor courses in Business Administration and Management. They visited organizations which had gone through a significant programme of change within the last 5 years. The owners, managers or HR managers responsible for changes were asked to fill in the questionnaires about the features of these organisational changes. Several issues regarding change management were covered, besides general information about the companies. Respondents were asked about the trigger events and the nature of changes, and about the process of change and participation in it. One group of questions asked leaders about employees’ attitude to change, another section sought information about the methods used in the process. In this paper, after a short literature review, we will analyse the adaptation methods used by organizations and the connection between the scope of change and employees’ attitude toward change.

[Intention for self-change across the life span: Focusing on concern about self-change].

Chishima, Yuta

2016-06-01

The purpose of the present study was to examine intention for self-change across the life span using measures of self-esteem, frequency of self-reflection, and concern about self-change. We hypothesized that: (a) Intention for self-change decreases with age because of increased self-esteem, decreased self-reflection and concern about self-change, and (b) Associations among self-esteem, frequency of self-reflection, and intention for self-change are mediated by concern about self-change. Participants (N = 997; age range, 15 to 69 yrs) completed an internet survey. ANOVA results suggested that intention for self-change, concern about self-change, and frequency of self-reflection decreased with age, and that self-esteem-scores increased with age. Simultaneous analysis of multiple age groups showed that for all groups of low self-esteem and frequent self-reflection promoted intention for self-change and that there were significant mediating effects for concern about self-change. Therefore, these findings supported out research hypotheses.

Bayesian change-point analysis reveals developmental change in a classic theory of mind task.

Although learning and development reflect changes situated in an individual brain, most discussions of behavioral change are based on the evidence of group averages. Our reliance on group-averaged data creates a dilemma. On the one hand, we need to use traditional inferential statistics. On the other hand, group averages are highly ambiguous when we need to understand change in the individual; the average pattern of change may characterize all, some, or none of the individuals in the group. Here we present a new method for statistically characterizing developmental change in each individual child we study. Using false-belief tasks, fifty-two children in two cohorts were repeatedly tested for varying lengths of time between 3 and 5 years of age. Using a novel Bayesian change point analysis, we determined both the presence and-just as importantly-the absence of change in individual longitudinal cumulative records. Whenever the analysis supports a change conclusion, it identifies in that child's record the most likely point at which change occurred. Results show striking variability in patterns of change and stability across individual children. We then group the individuals by their various patterns of change or no change. The resulting patterns provide scarce support for sudden changes in competence and shed new light on the concepts of "passing" and "failing" in developmental studies. Copyright © 2016 The Authors.

Culture and change blindness.

Science.gov (United States)

Masuda, Takahiko; Nisbett, Richard E

2006-03-04

Research on perception and cognition suggests that whereas East Asians view the world holistically, attending to the entire field and relations among objects, Westerners view the world analytically, focusing on the attributes of salient objects. These propositions were examined in the change-blindness paradigm. Research in that paradigm finds American participants to be more sensitive to changes in focal objects than to changes in the periphery or context. We anticipated that this would be less true for East Asians and that they would be more sensitive to context changes than would Americans. We presented participants with still photos and with animated vignettes having changes in focal object information and contextual information. Compared to Americans, East Asians were more sensitive to contextual changes than to focal object changes. These results suggest that there can be cultural variation in what may seem to be basic perceptual processes. 2006 Lawrence Erlbaum Associates, Inc.

Reliable Change Indices and Standardized Regression-Based Change Score Norms for Evaluating Neuropsychological Change in Children with Epilepsy

Science.gov (United States)

Busch, Robyn M.; Lineweaver, Tara T.; Ferguson, Lisa; Haut, Jennifer S.

2015-01-01

Reliable change index scores (RCIs) and standardized regression-based change score norms (SRBs) permit evaluation of meaningful changes in test scores following treatment interventions, like epilepsy surgery, while accounting for test-retest reliability, practice effects, score fluctuations due to error, and relevant clinical and demographic factors. Although these methods are frequently used to assess cognitive change after epilepsy surgery in adults, they have not been widely applied to examine cognitive change in children with epilepsy. The goal of the current study was to develop RCIs and SRBs for use in children with epilepsy. Sixty-three children with epilepsy (age range 6–16; M=10.19, SD=2.58) underwent comprehensive neuropsychological evaluations at two time points an average of 12 months apart. Practice adjusted RCIs and SRBs were calculated for all cognitive measures in the battery. Practice effects were quite variable across the neuropsychological measures, with the greatest differences observed among older children, particularly on the Children’s Memory Scale and Wisconsin Card Sorting Test. There was also notable variability in test-retest reliabilities across measures in the battery, with coefficients ranging from 0.14 to 0.92. RCIs and SRBs for use in assessing meaningful cognitive change in children following epilepsy surgery are provided for measures with reliability coefficients above 0.50. This is the first study to provide RCIs and SRBs for a comprehensive neuropsychological battery based on a large sample of children with epilepsy. Tables to aid in evaluating cognitive changes in children who have undergone epilepsy surgery are provided for clinical use. An excel sheet to perform all relevant calculations is also available to interested clinicians or researchers. PMID:26043163

Assessing changes in failure probability of dams in a changing climate

Science.gov (United States)

Mallakpour, I.; AghaKouchak, A.; Moftakhari, H.; Ragno, E.

2017-12-01

Dams are crucial infrastructures and provide resilience against hydrometeorological extremes (e.g., droughts and floods). In 2017, California experienced series of flooding events terminating a 5-year drought, and leading to incidents such as structural failure of Oroville Dam's spillway. Because of large socioeconomic repercussions of such incidents, it is of paramount importance to evaluate dam failure risks associated with projected shifts in the streamflow regime. This becomes even more important as the current procedures for design of hydraulic structures (e.g., dams, bridges, spillways) are based on the so-called stationary assumption. Yet, changes in climate are anticipated to result in changes in statistics of river flow (e.g., more extreme floods) and possibly increasing the failure probability of already aging dams. Here, we examine changes in discharge under two representative concentration pathways (RCPs): RCP4.5 and RCP8.5. In this study, we used routed daily streamflow data from ten global climate models (GCMs) in order to investigate possible climate-induced changes in streamflow in northern California. Our results show that while the average flow does not show a significant change, extreme floods are projected to increase in the future. Using the extreme value theory, we estimate changes in the return periods of 50-year and 100-year floods in the current and future climates. Finally, we use the historical and future return periods to quantify changes in failure probability of dams in a warming climate.

Conceptual Change regarding middle school students' experience with Global Climate Change

Science.gov (United States)

Golden, B. W.; Lutz, B.

2011-12-01

Given the complexity of the science involving climate change (IPCC, 2007), its lack of curricular focus within US K-12 schooling (Golden, 2009), and the difficulty in effecting conceptual change in science (Vosniadou, 2007), we sought to research middle school students' conceptions about climate change, in addition to how those conceptions changed during and as a result of a deliberately designed global climate change (GCC) unit. In a sixth grade classroom, a unit was designed which incorporated Argumentation-Driven Inquiry (Sampson & Grooms, 2010). That is, students were assigned to groups and asked to make sense of standard GCC data such as paleoclimate data from ice cores, direct temperature measurement, and Keeling curves, in addition to learning about the greenhouse effect in a modeling lesson (Hocking, et al, 1993). The students were then challenged, in groups, to create, on whiteboards, explanations and defend these explanations to and with their peers. They did two iterations of this argumentation. The first iteration focused on the simple identification of climate change patterns. The second focused on developing causal explanations for those patterns. After two rounds of such argumentation, the students were then asked to write (individually) a "final" argument which accounted for the given data. Interview and written data were analyzed prior to the given unit, during it, and after it, in order to capture complicated nuance that might escape detection by simpler research means such as surveys. Several findings emerged which promised to be of interest to climate change educators. The first is that many students tended to "know" many "facts" about climate change, but were unable to connect these disparate facts in any meaningful ways. A second finding is that while no students changed their entire belief systems, even after a robust unit which would seemingly challenge such, each student engaged did indeed modify the manner in which they discussed the

Moving Communities Toward Policy Change: APPEAL’s 4-Prong Policy Change Model

Science.gov (United States)

Tong, Elisa K.; Lew, Rod

2014-01-01

Policy change is recognized for underlying much of the success of tobacco control. However, there is little evidence and attention on how Asian American and Native Hawaiian and Pacific Islander (AA and NHPI) communities may engage in policy change. Challenges for AA and NHPI communities include the racial/ethnic and geographic diversity, and tobacco data accurately representing the communities. Over the past decade, the Asian Pacific Partners for Empowerment, Advocacy and Leadership (APPEAL) has worked to develop and implement policy change for AA and NHPI communities. This article describes APPEAL’s 4-prong policy change model, in the context of its overall strategic framework for policy change with communities that accounts for varying levels of readiness and leadership capacity, and targets four different levels of policy change (community, mainstream institution, legislative, and corporate). The health promotion implication of this framework for tobacco control policy engagement is for improving understanding of effective pathways to policy change, promoting innovative methods for policy analysis, and translating them into effective implementation and sustainability of policy initiatives. The APPEAL strategic framework can transcend into other communities and health topics that ultimately may contribute to the elimination of health disparities. PMID:23707962

Analysis for orbital rendezvous of Chang'E-5 using SBI technique

Science.gov (United States)

Huang, Y.; Shan, Q.; Li, P.

2016-12-01

Chang'E-5 will be launched in later 2017/early 2018 using a new generation rocket from Wenchang satellite launch center, Hainan, China. It is a lunar sampling return mission, and it is the first time for China to carry out orbital rendezvous and docking in the Moon. How to achieve orbital rendezvous successfully in the Moon is very important in Chang'E-5 mission. Orbital rendezvous will be implemented between an orbiter and an ascender 200 km above the Moon. The ground tracking techniques include range, Doppler and VLBI, and they will be used to track the orbiter and the ascender when the ascender is about 70 km farther away from the orbiter. Later the ascender will approach the orbiter automatically. As a successful example, in Chang'E-3, the differential phase delay (delta delay) data between the rover and the lander are obtained with a random error of about 1 ps, and the relative position of the rover is determined with an accuracy of several meters by using same beam VLBI (SBI) technique. Here the application of the SBI technique for Chang'E-5 orbital rendezvous is discussed. SBI technique can be used to track the orbiter and the ascender simultaneously when they are in the same beam. Delta delay of the two probes can be derived, and the measurement accuracy is much higher than that of the traditional VLBI data because of the cancelation of common errors. Theoretically it can result in a more accurate relative orbit between the two probes. In the simulation, different strategies are discussed to analyze the contribution of SBI data to the orbit accuracy improvement especially relative orbit between the orbiter and ascender. The simulation results show that the relative position accuracy of the orbiter and ascender can reach about 1 m with delta delay data of 10 ps.

Strategies are identified that family physicians can use to overcome the barriers.

Self-guided Change: The most common form of long-term, maintained health behavior change

Science.gov (United States)

Bishop, F Michler

2018-01-01

Millions of people change risky, health-related behaviors and maintain those changes. However, they often take years to change, and their unhealthy behaviors may harm themselves and others and constitute a significant cost to society. A review—similar in nature to a scoping review—was done of the literature related to long-term health behavior change in six areas: alcohol, cocaine and heroin misuse, gambling, smoking, and overeating. Based on the limited research available, reasons for change and strategies for changing and for maintaining change were also reviewed. Fifty years of research clearly indicate that as people age, in the case of alcohol, heroin and cocaine misuse, smoking, and gambling, 80–90 percent moderate or stop their unhealthy behaviors. The one exception is overeating; only 20 percent maintain their weight loss. Most of these changes, when they occur, appear to be the result of self-guided change. More ways to accelerate self-guided, health-related behavior change need to be developed and disseminated. PMID:29375888

Changing Energy Requirements in the Mediterranean Under Changing Climatic Conditions

Directory of Open Access Journals (Sweden)

George Demosthenous

2009-09-01

Full Text Available This study investigates the impacts of climate change on energy requirements in the Mediterranean. Energy requirements, especially for space heating and cooling, are closely linked to several weather variables, mainly air temperature. The analysis is based on daily temperature outputs from several regional climate models run at a resolution of 25 km × 25 km in the framework of EU project ENSEMBLES using the A1B emissions scenario. The impacts of changes in temperature on energy requirements are investigated using the concept of degree days, defined as the difference of mean air temperature from a base temperature. Base temperature should be chosen to coincide with the minimum energy consumption. In this way, changes in heating and cooling requirements between the reference and the future period are calculated and areas about to undergo large changes identified. These changes are calculated between a 30-year reference period 1961–1990 and a near future period 2021–2050 taking the ensemble mean of all regional climate models. The near-term future has been chosen instead of the frequently used end-of-the-century period to assist policy makers in their planning. In general, a decrease in energy requirements is projected under future milder winters and an increase under hotter summers.

Learning a Transferable Change Rule from a Recurrent Neural Network for Land Cover Change Detection

Directory of Open Access Journals (Sweden)

Haobo Lyu

2016-06-01

Full Text Available When exploited in remote sensing analysis, a reliable change rule with transfer ability can detect changes accurately and be applied widely. However, in practice, the complexity of land cover changes makes it difficult to use only one change rule or change feature learned from a given multi-temporal dataset to detect any other new target images without applying other learning processes. In this study, we consider the design of an efficient change rule having transferability to detect both binary and multi-class changes. The proposed method relies on an improved Long Short-Term Memory (LSTM model to acquire and record the change information of long-term sequence remote sensing data. In particular, a core memory cell is utilized to learn the change rule from the information concerning binary changes or multi-class changes. Three gates are utilized to control the input, output and update of the LSTM model for optimization. In addition, the learned rule can be applied to detect changes and transfer the change rule from one learned image to another new target multi-temporal image. In this study, binary experiments, transfer experiments and multi-class change experiments are exploited to demonstrate the superiority of our method. Three contributions of this work can be summarized as follows: (1 the proposed method can learn an effective change rule to provide reliable change information for multi-temporal images; (2 the learned change rule has good transferability for detecting changes in new target images without any extra learning process, and the new target images should have a multi-spectral distribution similar to that of the training images; and (3 to the authors’ best knowledge, this is the first time that deep learning in recurrent neural networks is exploited for change detection. In addition, under the framework of the proposed method, changes can be detected under both binary detection and multi-class change detection.

Effecting dietary change.

Science.gov (United States)

Adamson, Ashley J; Mathers, John C

2004-11-01

A world epidemic of diet-related chronic disease is currently being faced. In the UK incidence of obesity alone has tripled in the last 20 years and this trend is predicted to continue. Consensus exists for the urgent need for a change in diet and other lifestyle factors and for the direction and targets for this change. The evidence for how this change can be achieved is less certain. It has been established that disease processes begin in childhood. Recent evidence indicates that dietary habits too are established in childhood but that these habits are amenable to change. While establishing a healthy lifestyle in childhood is paramount, interventions have the potential to promote positive change throughout the life course. Success in reversing current trends in diet-related disease will depend on commitment from legislators, health professionals, industry and individuals, and this collaboration must seek to address not only the food choices of the individual but also the environment that influences such choices. Recent public health policy development in England, if fully supported and implemented, is a positive move towards this goal. Evidence for effective strategies to promote dietary change at the individual level is emerging and three reviews of this evidence are discussed. In addition, three recent dietary intervention studies, in three different settings and with different methods and aims, are presented to illustrate methods of effecting dietary change. Further work is required on what factors influence the eating behaviour and physical activity of individuals. There is a need for further theory-based research on which to develop more effective strategies to enable individuals to adopt healthier lifestyles.

Changing families, changing workplaces.

Science.gov (United States)

Bianchi, Suzanne M

2011-01-01

American families and workplaces have both changed dramatically over the past half-century. Paid work by women has increased sharply, as has family instability. Education-related inequality in work hours and income has grown. These changes, says Suzanne Bianchi, pose differing work-life issues for parents at different points along the income distribution. Between 1975 and 2009, the labor force rate of mothers with children under age eighteen increased from 47.4 percent to 71.6 percent. Mothers today also return to work much sooner after the birth of a child than did mothers half a century ago. High divorce rates and a sharp rise in the share of births to unmarried mothers mean that more children are being raised by a single parent, usually their mother. Workplaces too have changed, observes Bianchi. Today's employees increasingly work nonstandard hours. The well-being of highly skilled workers and less-skilled workers has been diverging. For the former, work hours may be long, but income has soared. For lower-skill workers, the lack of "good jobs" disconnects fathers from family obligations. Men who cannot find work or have low earnings potential are much less likely to marry. For low-income women, many of whom are single parents, the work-family dilemma is how to care adequately for children and work enough hours to support them financially. Jobs for working-class and lower middle-class workers are relatively stable, except in economic downturns, but pay is low, and both parents must work full time to make ends meet. Family income is too high to qualify for government subsidized child care, but too low to afford high-quality care in the private market. These families struggle to have a reasonable family life and provide for their family's economic well-being. Bianchi concludes that the "work and family" problem has no one solution because it is not one problem. Some workers need more work and more money. Some need to take time off around the birth of a child

Climate variability: Possible changes with climate change and impacts on crop yields

International Nuclear Information System (INIS)

Mearns, L.O.

1991-01-01

A pilot study was carried out of the sensitivity of the CERES wheat model, a deterministic crop-climate model, to changes in the interannual variability of temperature and precipitation. The study was designed to determine the effect of changed temperature variance on the mean and variance of the simulated yields, to compare the effect with the effect of mean temperature changes, and to determine the interacting effects of changes in mean and variance of temperature. The CERES model was applied to 29 cropping years (1952-1980), using three different soil types and two different management practices (fully irrigated and dryland). The coefficients of variation of the yields for irrigated and dryland conditions are plotted against variance change. It was found that in both management systems, the yield response is usually greater to increases rather than decreases in variance. The combined effect of mean and variance temperature changes are most striking under irrigated conditions, with a dramatic decrease in yield variability in the high mean climate change scenario with decreased temperature variance. This suggests that the variability decrease might mitigate the effect of a mean increase in temperature. This result is not found with the dryland case, where decreased temperature variability has little impact on yield variability. 12 refs., 4 figs

Contributions of changes in climatology and perturbation and the resulting nonlinearity to regional climate change.

Future changes in large-scale climatology and perturbation may have different impacts on regional climate change. It is important to understand the impacts of climatology and perturbation in terms of both thermodynamic and dynamic changes. Although many studies have investigated the influence of climatology changes on regional climate, the significance of perturbation changes is still debated. The nonlinear effect of these two changes is also unknown. We propose a systematic procedure that extracts the influences of three factors: changes in climatology, changes in perturbation and the resulting nonlinear effect. We then demonstrate the usefulness of the procedure, applying it to future changes in precipitation. All three factors have the same degree of influence, especially for extreme rainfall events. Thus, regional climate assessments should consider not only the climatology change but also the perturbation change and their nonlinearity. This procedure can advance interpretations of future regional climates.

Asia's changing role in global climate change.

Science.gov (United States)

Siddiqi, Toufiq A

2008-10-01

Asia's role in global climate change has evolved significantly from the time when the Kyoto Protocol was being negotiated. Emissions of carbon dioxide, the principal greenhouse gas, from energy use in Asian countries now exceed those from the European Union or North America. Three of the top five emitters-China, India, and Japan, are Asian countries. Any meaningful global effort to address global climate change requires the active cooperation of these and other large Asian countries, if it is to succeed. Issues of equity between countries, within countries, and between generations, need to be tackled. Some quantitative current and historic data to illustrate the difficulties involved are provided, and one approach to making progress is suggested.

Contribution of human and climate change impacts to changes in streamflow of Canada.

Climate change exerts great influence on streamflow by changing precipitation, temperature, snowpack and potential evapotranspiration (PET), while human activities in a watershed can directly alter the runoff production and indirectly through affecting climatic variables. However, to separate contribution of anthropogenic and natural drivers to observed changes in streamflow is non-trivial. Here we estimated the direct influence of human activities and climate change effect to changes of the mean annual streamflow (MAS) of 96 Canadian watersheds based on the elasticity of streamflow in relation to precipitation, PET and human impacts such as land use and cover change. Elasticities of streamflow for each watershed are analytically derived using the Budyko Framework. We found that climate change generally caused an increase in MAS, while human impacts generally a decrease in MAS and such impact tends to become more severe with time, even though there are exceptions. Higher proportions of human contribution, compared to that of climate change contribution, resulted in generally decreased streamflow of Canada observed in recent decades. Furthermore, if without contributions from retreating glaciers to streamflow, human impact would have resulted in a more severe decrease in Canadian streamflow.

Multiscale Region-Level VHR Image Change Detection via Sparse Change Descriptor and Robust Discriminative Dictionary Learning

Directory of Open Access Journals (Sweden)

Yuan Xu

2015-01-01

Full Text Available Very high resolution (VHR image change detection is challenging due to the low discriminative ability of change feature and the difficulty of change decision in utilizing the multilevel contextual information. Most change feature extraction techniques put emphasis on the change degree description (i.e., in what degree the changes have happened, while they ignore the change pattern description (i.e., how the changes changed, which is of equal importance in characterizing the change signatures. Moreover, the simultaneous consideration of the classification robust to the registration noise and the multiscale region-consistent fusion is often neglected in change decision. To overcome such drawbacks, in this paper, a novel VHR image change detection method is proposed based on sparse change descriptor and robust discriminative dictionary learning. Sparse change descriptor combines the change degree component and the change pattern component, which are encoded by the sparse representation error and the morphological profile feature, respectively. Robust change decision is conducted by multiscale region-consistent fusion, which is implemented by the superpixel-level cosparse representation with robust discriminative dictionary and the conditional random field model. Experimental results confirm the effectiveness of the proposed change detection technique.

Changes in the Perceived Risk of Climate Change: Evidence from Sudden Climatic Events

Science.gov (United States)

Anttila-Hughes, J. K.

2009-12-01

In the course of the past two decades the threat of anthropogenic climate change has moved from a scientific concern of relative obscurity to become one of the largest environmental and public goods problems in history. During this period public understanding of the risk of climate change has shifted from negligible to quite large. In this paper I propose a means of quantifying this change by examining how sudden events supporting the theory of anthropogenic climate change have affected carbon intensive companies' stock prices. Using CAPM event study methodology for companies in several carbon-intensive industries, I find strong evidence that markets have been reacting to changes in the scientific evidence for climate change for some time. Specifically, the change in magnitude of response over time seems to indicate that investors believed climate change was a potentially serious risk to corporate profits as early as the mid 1990s. Moreover, market reaction dependence on event type indicates that investors are differentiating between different advances in the scientific knowledge. Announcements by NASA GISS that the previous year was a “record hot year” for the globe are associated with negative excess returns, while news of ice shelf collapses are associated with strong positive excess returns. These results imply that investors are aware of how different aspects of climate change will affect carbon intensive companies, specifically in terms of the link between warming in general and polar ice cover. This implies that policy choices based on observable public opinion have lagged actual private concern over climate change's potential threat.

Climate Change, Politics and Religion: Australian Churchgoers’ Beliefs about Climate Change

Directory of Open Access Journals (Sweden)

Miriam Pepper

2016-05-01

Full Text Available A growing literature has sought to understand the relationships between religion, politics and views about climate change and climate change policy in the United States. However, little comparative research has been conducted in other countries. This study draws on data from the 2011 Australian National Church Life Survey to examine the beliefs of Australian churchgoers from some 20 denominations about climate change—whether or not it is real and whether it is caused by humans—and political factors that explain variation in these beliefs. Pentecostals, Baptist and Churches of Christ churchgoers, and people from the smallest Protestant denominations were less likely than other churchgoers to believe in anthropogenic climate change, and voting and hierarchical and individualistic views about society predicted beliefs. There was some evidence that these views function differently in relation to climate change beliefs depending on churchgoers’ degree of opposition to gay rights. These findings are of interest not only for the sake of international comparisons, but also in a context where Australia plays a role in international climate change politics that is disproportionate to its small population.

Mapping change in large networks.

Directory of Open Access Journals (Sweden)

Martin Rosvall

2010-01-01

Full Text Available Change is a fundamental ingredient of interaction patterns in biology, technology, the economy, and science itself: Interactions within and between organisms change; transportation patterns by air, land, and sea all change; the global financial flow changes; and the frontiers of scientific research change. Networks and clustering methods have become important tools to comprehend instances of these large-scale structures, but without methods to distinguish between real trends and noisy data, these approaches are not useful for studying how networks change. Only if we can assign significance to the partitioning of single networks can we distinguish meaningful structural changes from random fluctuations. Here we show that bootstrap resampling accompanied by significance clustering provides a solution to this problem. To connect changing structures with the changing function of networks, we highlight and summarize the significant structural changes with alluvial diagrams and realize de Solla Price's vision of mapping change in science: studying the citation pattern between about 7000 scientific journals over the past decade, we find that neuroscience has transformed from an interdisciplinary specialty to a mature and stand-alone discipline.

Changes in crash risk following re-timing of traffic signal change intervals.

Science.gov (United States)

Retting, Richard A; Chapline, Janella F; Williams, Allan F

2002-03-01

More than I million motor vehicle crashes occur annually at signalized intersections in the USA. The principal method used to prevent crashes associated with routine changes in signal indications is employment of a traffic signal change interval--a brief yellow and all-red period that follows the green indication. No universal practice exists for selecting the duration of change intervals, and little is known about the influence of the duration of the change interval on crash risk. The purpose of this study was to estimate potential crash effects of modifying the duration of traffic signal change intervals to conform with values associated with a proposed recommended practice published by the Institute of Transportation Engineers. A sample of 122 intersections was identified and randomly assigned to experimental and control groups. Of 51 eligible experimental sites, 40 (78%) needed signal timing changes. For the 3-year period following implementation of signal timing changes, there was an 8% reduction in reportable crashes at experimental sites relative to those occurring at control sites (P = 0.08). For injury crashes, a 12% reduction at experimental sites relative to those occurring at control sites was found (P = 0.03). Pedestrian and bicycle crashes at experimental sites decreased 37% (P = 0.03) relative to controls. Given these results and the relatively low cost of re-timing traffic signals, modifying the duration of traffic signal change intervals to conform with values associated with the Institute of Transportation Engineers' proposed recommended practice should be strongly considered by transportation agencies to reduce the frequency of urban motor vehicle crashes.

Commitment to Change and Challenges to Implementing Changes After Workplace-Based Assessment Rater Training.

Kogan, Jennifer R; Conforti, Lisa N; Yamazaki, Kenji; Iobst, William; Holmboe, Eric S

2017-03-01

Faculty development for clinical faculty who assess trainees is necessary to improve assessment quality and impor tant for competency-based education. Little is known about what faculty plan to do differently after training. This study explored the changes faculty intended to make after workplace-based assessment rater training, their ability to implement change, predictors of change, and barriers encountered. In 2012, 45 outpatient internal medicine faculty preceptors (who supervised residents) from 26 institutions participated in rater training. They completed a commitment to change form listing up to five commitments and ranked (on a 1-5 scale) their motivation for and anticipated difficulty implementing each change. Three months later, participants were interviewed about their ability to implement change and barriers encountered. The authors used logistic regression to examine predictors of change. Of 191 total commitments, the most common commitments focused on what faculty would change about their own teaching (57%) and increasing direct observation (31%). Of the 183 commitments for which follow-up data were available, 39% were fully implemented, 40% were partially implemented, and 20% were not implemented. Lack of time/competing priorities was the most commonly cited barrier. Higher initial motivation (odds ratio [OR] 2.02; 95% confidence interval [CI] 1.14, 3.57) predicted change. As anticipated difficulty increased, implementation became less likely (OR 0.67; 95% CI 0.49, 0.93). While higher baseline motivation predicted change, multiple system-level barriers undermined ability to implement change. Rater-training faculty development programs should address how faculty motivation and organizational barriers interact and influence ability to change.

Change Ringing - communicating climate change through contemporary classical music

Science.gov (United States)

Kapur, Ravi; Osborn, Laurence; Shenai, Peter

2016-04-01

Change Ringing is a collaborative artwork by artist Peter Shenai and composer Laurence Osborn that forms around a playable sculpture and a large-scale composition. The sculpture incorporates a set of six bronze bells designed and cast by artist Peter Shenai. Their shapes are mathematically derived from graphic statistical representations of summer temperatures at seventeen-year intervals over the course of the twentieth century. Arranged according to the chronology of their corresponding data sets and struck in order, the bells voice a series of inharmonic spectra that communicate sonically the story of climate change during the twentieth century. This series forms the basis for Laurence Osborn's twenty-five minute composition, scored for string orchestra and the bells themselves. In Change Ringing, an artwork that combines music, sculpture, performance, and ritual, we want to move audiences and, in doing so, facilitate their engagement with ideas that are highly relevant today. We believe that the medium of musically organized sound, so often wrongly dismissed as "abstract" and non-referential, can be a more than adequate reflection of lived human experience in the 21st Century, and we work in the hope that Change Ringing will connect with contemporary audiences on the most fundamental level.

The Report aims to improve understanding about the linkages between trade and climate change. It shows that trade intersects with climate change in a multitude of ways. For example, governments may introduce a variety of policies, such as regulatory measures and economic incentives, to address climate change. This complex web of measures may have an impact on international trade and the multilateral trading system. The Report begins with a summary of the current state of scientific knowledge on climate change and on the options available for responding to the challenge of climate change. The scientific review is followed by a part on the economic aspects of the link between trade and climate change, and these two parts set the context for the subsequent parts of the Report, which looks at the policies introduced at both the international and national level to address climate change. The part on international policy responses to climate change describes multilateral efforts to reduce greenhouse gas emissions and to adapt to the effects of climate change, and also discusses the role of the current trade and environment negotiations in promoting trade in technologies that aim to mitigate climate change. The final part of the Report gives an overview of a range of national policies and measures that have been used in a number of countries to reduce greenhouse gas emissions and to increase energy efficiency. It presents key features in the design and implementation of these policies, in order to draw a clearer picture of their overall effect and potential impact on environmental protection, sustainable development and trade. It also gives, where appropriate, an overview of the WTO rules that may be relevant to such measures. (author)

The Intergovernmental Panel on Climate Change (IPCC) has finalized its Third Assessment Report. Among its conclusions is that we must expect continued changes in our climate, despite our efforts to reduce greenhouse gas emissions. Planning for and adapting to climate change are therefore necessary. As a starting point, CICERO has written this short note on expected impacts in Norway. The main conclusions are that (1) Adaptation to climate change is necessary (2) Substantial impacts are expected for several important sectors in Norway (3) The local and central authorities should now consider and start planning for adaptation measures. (4) There is still a need for more knowledge about potential impacts of climate change in Norway. (author)

This paper presents a new approach to the design and implementation of community change efforts like a System of Care. Called the ABLe Change Framework, the model provides simultaneous attention to the content and process of the work, ensuring effective implementation and the pursuit of systems change. Three key strategies are employed in this model to ensure the integration of content and process efforts and effective mobilization of broad scale systems change: Systemic Action Learning Teams, Simple Rules, and Small Wins. In this paper we describe the ABLe Change Framework and present a case study in which we successfully applied this approach to one system of care effort in Michigan.

N-doping into GeTe is investigated with the aim of reducing the volume change upon crystallization, which usually induces a huge internal stress in phase-change memory devices. It is demonstrated that the thickness change upon crystallization of a N-doped GeTe (GeTeN) film is almost zero when N is doped in an appropriate amount. Cracks resulting from the stress caused by volume change disappear and the mean crystal size decreases by more than 50% upon N-doping into GeTe. It is thought that the volume-change-free behaviour is due to the formation of low-density nitride and grain refinement. (paper)

On the role of circulation changes in future Northern Hemisphere hydroclimate change

Science.gov (United States)

Seager, R.; Ting, M.; Simpson, I.; Shaw, T.

2015-12-01

The "dry-get-drier, wet-get-wetter", otherwise known as "rich-get-richer, poor-get-poorer" concept of the hydrological cycle response to rising greenhouse gases was a major advance in terms of perception of climate change in the research community and the winder public. It provides a good description of hydroclimate change in many regions but especially over the oceans. Here there is a clear divide between wet regions, with positive precipitation minus evaporation (P-E), and dry regions with negative P-E. However over land, long term P-E is either zero or positive and balanced by streamflow and it is not so simple to divide between wet and dry regions. What is more, the simple wet-get-wetter, dry-get-drier paradigm is based only on thermodynamics with rising humidity causing increased amplitude of moisture convergence and moisture divergence and, hence, larger variations in P-E. It is now being realized more and more that changes in atmospheric circulation can also drive changes in moisture convergence/divergence and that a full explanation of hydrological cycle change requires attention to circulation change. This will be illustrated with reference to North America and the Mediterranean region. In both case changes in the mean circulation are important drivers of regional hydroclimate change. Model-projected North American hydroclimate change in winter is strongly influenced by a lengthening of the zonal scale of intermediate-scale stationary waves forced by extratropical heating. Wetting at the west coast, drying in the interior southwest and wetting at the US east coast are stronger in models that have a climatological wave field that exaggerates these waves than in models that have more realistic amplitude wave fields. Intense Mediterranean region drying in both summer and winter is also explained in part by shifts towards regional high pressure that, as of now, have not been fully explained. In neither southwest North America nor the Mediterranean, despite the

To support the development of a National Climate Change Policy Framework (NCCPF) and a further harmonization of climate change related activities in Ghana, the Ministry of Finance and Economic Planning (MoFEP) and the Ministry of Environment, Science and Technology (MEST) expressed demand for a mapping of the most important past and current climate change related initiatives in the country, and of international climate change related funding opportunities, that Ghana might be able to access. The initiatives mapping demonstrates Ghana's longstanding engagement with climate change, dating back to more than 15 years ago. The report shows a multitude of activities including a number of large (5 mln. USD to > 100 mln. USD), GEF or World Bank financed projects, and a range of smaller projects (in the order of 100 000 - 500 000 USD). The majority of current initiatives are related to forestry and REDD. This report concludes with a discussion on observed trends, such as a broadening involvement of MDAs in adaptation initiatives and a focus on low carbon growth, and of points for attention, such as a need for coordination, for private sector involvement and supporting systems (such as institutional capacity, governance and monitoring systems)

The effects of transformational leadership on the outcomes of specific change initiatives are not well understood. Conversely, organizational change studies have examined leader behaviors during specific change implementations yet have failed to link these to broader leadership theories. In this study, the authors investigate the relationship between transformational and change leadership and followers' commitment to a particular change initiative as a function of the personal impact of the changes. Transformational leadership was found to be more strongly related to followers' change commitment than change-specific leadership practices, especially when the change had significant personal impact. For leaders who were not viewed as transformational, good change-management practices were found to be associated with higher levels of change commitment. Copyright 2008 APA

Because the nervous system is at the forefront of animals' interactions with the environment, the neurobiological implications of climate change are central to understanding how individuals, and ultimately populations, will respond to global warming. Evidence is accumulating for individual level, mechanistic effects of climate change on nervous system development and performance. Climate change can also alter sensory stimuli, changing the effectiveness of sensory and cognitive systems for achieving biological fitness. At the population level, natural selection forces stemming from directional climate change may drive rapid evolutionary change in nervous system structure and function.

Objective: To report the bone X-ray changes in phenylketonuria. Methods: Thirty-seven cases of phenylketonuria were reported. Among the 37 cases, 25 were males and 12 were females. The age of this series ranged from 6 months to 9 years. X-ray examination of the hands, wrists, and knees and laboratory examination were performed in all cases. Results: The bone changes of the 37 cases were divided into 6 groups: no abnormal findings, osteoporosis, metaphyseal changes, special changes, the bone age method, and miscellaneous changes. Special changes included striations into the diaphysis (12 cases) and beak of the metaphyseal margin (21 cases). Conclusion: The mechanism causing the bone changes in phenylketonuria is not quite clear. The authors conclude that specific bone changes may be important X-ray signs suggestive of phenylketonuria

Climate change and skin disease.

Despite commanding essentially universal scientific consensus, climate change remains a divisive and poorly understood topic in the United States. Familiarity with this subject is not just for climate scientists. The impact of climate change on human morbidity and mortality may be considerable; thus, physicians also should be knowledgeable in this realm. Climate change science can seem opaque and inferential, creating fertile ground for political polemics and undoubtedly contributing to confusion among the general public. This puts physicians in a pivotal position to facilitate a practical understanding of climate change in the public sphere by discussing changes in disease patterns and their possible relationship to a changing climate. This article provides a background on climate change for dermatologists and highlights how climate change may impact the management of skin disease across the United States.

Climate Change Mitigation A Balanced Approach to Climate Change

CERN Document Server

2012-01-01

This book provides a fresh and innovative perspective on climate change policy. By emphasizing the multiple facets of climate policy, from mitigation to adaptation, from technological innovation and diffusion to governance issues, it contains a comprehensive overview of the economic and policy dimensions of the climate problem. The keyword of the book is balance. The book clarifies that climate change cannot be controlled by sacrificing economic growth and many other urgent global issues. At the same time, action to control climate change cannot be delayed, even though gradually implemented. Therefore, on the one hand climate policy becomes pervasive and affects all dimensions of international policy. On the other hand, climate policy cannot be too ambitious: a balanced approach between mitigation and adaptation, between economic growth and resource management, between short term development efforts and long term innovation investments, should be adopted. I recommend its reading. Carlo Carraro, President, Ca�...

The development of the future atmospheric chemical composition, with respect of NO{sub y} and O{sub 3} is investigated by means of the off-line coupled dynamic-chemical general circulation model ECHAM3/CHEM. Two time slice experiments have been performed for the years 1992 and 2015, which include changes in sea surface temperatures, greenhouse gas concentrations, emissions of CFCs, NO{sub x} and other species, i.e., the 2015 simulation accounts for changes in chemically relevant emissions and for a climate change and its impact on air chemistry. The 2015 simulation clearly shows a global increase in ozone except for large areas of the lower stratosphere, where no significant changes or even decreases in the ozone concentration are found. For a better understanding of the importance of (A) emissions like NO{sub x} and CFCs, (B) future changes of air temperature and water vapour concentration, and (C) other dynamic parameters, like precipitation and changes in the circulation, i.e. wind speed, diabatic circulation, stratosphere-troposphere-exchange, the simulation of the future atmosphere has been performed stepwise. This method requires a climate-chemistry model without interactive coupling of chemical species. Model results show that the direct effect of emissions (A) plays a major role for the composition of the future atmosphere, but they also clearly show that climate change has a significant impact and strongly reduces the NO{sub y} and ozone concentration in the lower stratosphere.

Accurate and precise measurements of creatinine are necessary to evaluate changes in kidney function related to a decreased glomerular filtration rate (GFR). When serial measurements of creatinine are monitored in an individual, it is useful to know what magnitude of an analytical change in creatinine indicates a true physiologic/biologic change in plasma creatinine that might warrant clinical intervention. We compared results between three different methods for creatinine using large chemistry analyzers, two based on alkaline picrate (AP1 and AP2), and one based on dry-slide enzymatic conversion (ENZ). On each of three different segments or days of the study spaced 1-2months apart, we selected 10 different plasma samples having creatinine concentrations ranging from about 0.5mg/dL to 4.5mg/dL (44 to 400μmol/L). Each sample was analyzed in triplicate on each of two same-model analyzers at each institution, then from this data we determined the precision of each model of analyzer. The within-instrument precision of each analyzer was evaluated from the differences between the triplicate results on each sample by each analyzer (mean and SD of the differences). The between-instrument precision was evaluated as the differences between results on the same sample (1, 2, 3, etc.) analyzed on different analyzers of the same model (A and B). This between-analyzer precision data was used to determine both the range and mean±2SD of the differences that could be used to indicate that greater changes in creatinine concentrations would represent a biologic change. The within-instrument precision was best for the ENZ method in comparison to the two alkaline picrate rate methods. The between-instrument precision of the 90 consecutive measurements (30 samples×triplicate analyses) between the same-model analyzers were (mean and SD of differences in mg/dL): -0.018 and 0.029 (ENZ); 0.016 and 0.11 (AP1), and -0.058 and 0.071 (AP2).

The family food environment is an important influence in the development of children's dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1) investigate the association between the food environment at baseline and change in children's saturated fat intake; and (2) to explore whether a change in the food environment was associated with a change in children's saturated fat intake. Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30 minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment--Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children's dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat) were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (pchange in saturated fat. An increase in nutrition knowledge (β=-0.2), perceived responsibility (β=-0.3) and restriction (β=-0.3) from baseline to week 12 were associated with greater reduction in saturated fat intake. The present study was one of the first to quantify changes in the family food environment, and identify a number of factors which were associated with a positive dietary change. Because interventions focus on behaviour change, the findings may provide specific targets for intervention strategies in the future. Australia New Zealand Clinical

Attention to change: A multilevel theory on the process of emergent continuous organizational change.

Science.gov (United States)

Wee, Elijah X M; Taylor, M Susan

2018-01-01

Increasingly, continuous organizational change is viewed as the new reality for organizations and their members. However, this model of organizational change, which is usually characterized by ongoing, cumulative, and substantive change from the bottom up, remains underexplored in the literature. Taking a multilevel approach, the authors develop a theoretical model to explain the mechanisms behind the amplification and accumulation of valuable, ongoing work-unit level changes over time, which then become substantial changes at the organizational level. Drawing on the concept of emergence, they first focus on the cognitive search mechanisms of work-unit members and managers to illustrate how work-unit level routine changes may be amplified to the organization through 2 unique processes: composition and compilation emergence. The authors then discuss the managers' role in creating a sense of coherence and meaning for the accumulation of these emergent changes over time. They conclude this research by discussing the theoretical implications of their model for the existing literature of organizational change.

Construction of climate change scenarios from transient climate change experiments for the IPCC impacts assessment

International Nuclear Information System (INIS)

Viner, D.; Hulme, M.; Raper, S.C.B.; Jones, P.D.

1994-01-01

This paper outlines the different methods which may be used for the construction of regional climate change scenarios. The main focus of the paper is the construction of global climate change scenarios from climate change experiments carried out using General Circulation Models (GCMS) An introduction to some GCM climate change experiments highlights the difference between model types and experiments (e.g., equilibrium or transient). The latest generation of climate change experiments has been performed using fully coupled ocean-atmosphere GCMS. These allow transient simulations of climate change to be performed with respect to a given greenhouse gas forcing scenario. There are, however, a number of problems with these simulations which pose difficulties for the construction of climate change scenarios for use in climate change impacts assessment. The characteristics of the transient climate change experiments which pose difficulties for the construction of climate change scenarios are discussed. Three examples of these problems are: different climate change experiments use different greenhouse gas concentration scenarios; the 'cold-start' problem makes it difficult to link future projections of climate change to a given calendar year; a drift of the climate is noticeable in the control simulations. In order to construct climate change scenarios for impacts assessment a method has therefore to be employed which addresses these problems. At present the climate modeling and climate change impacts communities are somewhat polarized in their approach to spatial scales. Current GCMs model the climate at resolutions larger than 2.5 x 3.75 degree, while the majority of impacts assessment studies are undertaken at scales below 50km (or 0.5 degree). This paper concludes by addressing the problems in bringing together these two different modeling perspectives by presenting a number of regional climate change scenarios. 35 refs., 8 figs., 2 tabs

You changed your mind! Infants interpret a change in word as signaling a change in an agent's goals.

Language provides information about our psychological states. For instance, adults can use language to convey information about their goals or preferences. The current research examined whether 14- and 12-month-old infants could interpret a change in an agent's word as signaling a change in her goals. In two experiments, 14-month-olds (Experiment 1) and 12-month-olds (Experiment 2) were first familiarized to an event in which an agent uttered a novel word and then reached for one of two novel objects. During the test trials, the agent uttered a different novel word (different-word condition) or the same word (same-word condition) and then reached for the same object or the other object. Both 14- and 12-month-olds in the different-word condition expected the agent to change her goal and reach for the other object. In contrast, the infants in the same-word condition expected the agent to maintain her goal. In Experiment 3, 12-month-olds who heard two distinct sounds instead of the agent's novel words expected the agent to maintain her goal regardless of the change in the nonlinguistic sounds. Together, these results indicate that by 12months of age infants can use an agent's verbal information to detect a change in her goals. Copyright © 2017 Elsevier Inc. All rights reserved.

Ocean Observations of Climate Change

Science.gov (United States)

Chambers, Don

2016-01-01

The ocean influences climate by storing and transporting large amounts of heat, freshwater, and carbon, and exchanging these properties with the atmosphere. About 93% of the excess heat energy stored by the earth over the last 50 years is found in the ocean. More than three quarters of the total exchange of water between the atmosphere and the earth's surface through evaporation and precipitation takes place over the oceans. The ocean contains 50 times more carbon than the atmosphere and is at present acting to slow the rate of climate change by absorbing one quarter of human emissions of carbon dioxide from fossil fuel burning, cement production, deforestation and other land use change.Here I summarize the observational evidence of change in the ocean, with an emphasis on basin- and global-scale changes relevant to climate. These include: changes in subsurface ocean temperature and heat content, evidence for regional changes in ocean salinity and their link to changes in evaporation and precipitation over the oceans, evidence of variability and change of ocean current patterns relevant to climate, observations of sea level change and predictions over the next century, and biogeochemical changes in the ocean, including ocean acidification.

Frameworks for change in healthcare organisations: a formative evaluation of the NHS Change Model.

Science.gov (United States)

Martin, Graham P; Sutton, Elizabeth; Willars, Janet; Dixon-Woods, Mary

2013-08-01

Organisational change in complex healthcare systems is a multifaceted process. The English National Health Service recently introduced a 'Change Model' that seeks to offer an evidence-based framework for guiding change. We report findings from a formative evaluation of the NHS Change Model and make recommendations for those developing the Model and its users. The evaluation involved 28 interviews with managers and clinicians making use of the Change Model in relation to a variety of projects. Interviews were fully transcribed and were analysed using an approach based on the Framework method. Participants saw the Change Model as valuable and practically useful. Fidelity to core principles of the Model was variable: participants often altered the Model, especially when using it to orchestrate the work of others. In challenging organisational contexts, the Change Model was sometimes used to delegitimise opposition rather than identify shared purpose among different interest groups. Those guiding change may benefit from frameworks, guidance and toolkits to structure and inform their planning and activities. Participants' experiences suggested the Change Model has much potential. Further work on its design and on supporting materials may optimise the approach, but its utility rests in particular on organisational cultures that support faithful application. © The Author(s) 2013 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

Politics of change: the discourses that inform organizational change and their capacity to silence.

Science.gov (United States)

McMillan, Kim

2016-09-01

Changes in healthcare organizations are inevitable and occurring at unprecedented rates. Such changes greatly impact nurses and their work, yet these experiences are rarely explored. Organizational change discourses remain grounded in perspectives that explore and explain systems, often not the people within them. Change processes in healthcare organizations informed by such organizational discourses validate only certain perspectives and forms of knowledge. This fosters exclusionary practices, limiting the capacity of certain individuals or groups of individuals to effectively contribute to change discourses and processes. The reliance on mainstream organizational discourses in healthcare organizations has left little room for the exploration of diverse perspectives on the subject of organizational change, particularly those of nurses. Michel Foucault's work challenges dominant discourse and suggest that strong reliance's on specific discourses effectively disqualify certain forms of knowledge. Foucault's writings on disqualified knowledge and parrhesia (truth telling and frank speech) facilitate the critical exploration of discourses that inform change in healthcare organizations and nurses capacities to contribute to organizational discourses. This paper explores the capacity of nurses to speak their truths within rapidly and continuously changing healthcare organizations when such changes are often driven by discourses not derived from nursing knowledge or experience. © 2016 John Wiley & Sons Ltd.

Effect of lunar gravity models on Chang'E-2 orbit determination using VLBI tracking data

Full Text Available The precise orbit determination of Chang'E-2 is the most important issue for successful mission and scientific applications, while the lunar gravity field model with big uncertainties has large effect on Chang'E-2 orbit determination. Recently, several new gravity models have been produced using the latest lunar satellites tracking data, such as LP165P, SGM150J, GL0900D and GRGM900C. In this paper, the four gravity models mentioned above were evaluated through the power spectra analysis, admittance and coherence analysis. Effect of four lunar gravity models on Chang'E-2 orbit determination performance is investigated and assessed using Very Long Baseline Interferometry (VLBI tracking data. The overlap orbit analysis, the posteriori data residual, and the orbit prediction are used to evaluate the orbit precision between successive arcs. The LP165P model has better orbit overlap performance than the SGM150J model for Chang'E-2100 km × 100 km orbit and the SGM150J model performs better for Chang'E-2100 km × 15 km orbit, while GL0900D and GRGM900C have the best orbit overlap results for the two types of Chang'E-2 orbit. For the orbit prediction, GRGM900C has the best orbit prediction performance in the four models.

Even though most work on change-point estimation focuses on changes in the mean, changes in the variance or in the tail distribution can lead to more extreme events. In this paper, we develop a new method of detecting and estimating the change-points in the tail of multiple time series data. In addition, we adapt existing tail change-point detection methods to our specific problem and conduct a thorough comparison of different methods in terms of performance on the estimation of change-points and computational time. We also examine three locations on the U.S. northeast coast and demonstrate that the methods are useful for identifying changes in seasonally extreme warm temperatures.

2009-12-01

Previous research on appraisal theories of emotion has shown that emotions and appraisals are related but has not specified the nature of the relationships. This research examined the functional forms of appraisal-emotion relationships and demonstrated that for all seven appraisals studied, appraisals relate to emotions in an S-shaped (ogival) fashion: Changes in appraisals at extreme levels are associated with only small changes in emotions, but changes at moderate levels are associated with substantial changes in emotions. With a few exceptions, ogival relationships were found for the relationships between seven appraisals (Goal Achievement Expectancy, Agency, Control, Certainty, Fairness, Pleasantness, and Motive Congruence) and numerous relevant emotions across different sample-types, cultures, and methods.

Does facial processing prioritize change detection?: change blindness illustrates costs and benefits of holistic processing.

Science.gov (United States)

Wilford, Miko M; Wells, Gary L

2010-11-01

There is broad consensus among researchers both that faces are processed more holistically than other objects and that this type of processing is beneficial. We predicted that holistic processing of faces also involves a cost, namely, a diminished ability to localize change. This study (N = 150) utilized a modified change-blindness paradigm in which some trials involved a change in one feature of an image (nose, chin, mouth, hair, or eyes for faces; chimney, porch, window, roof, or door for houses), whereas other trials involved no change. People were better able to detect the occurrence of a change for faces than for houses, but were better able to localize which feature had changed for houses than for faces. Half the trials used inverted images, a manipulation that disrupts holistic processing. With inverted images, the critical interaction between image type (faces vs. houses) and task (change detection vs. change localization) disappeared. The results suggest that holistic processing reduces change-localization abilities.

The Impact of Climate Change on Recent Vegetation Changes on Dovrefjell, Norway

Directory of Open Access Journals (Sweden)

Jarle Inge Holten

2011-01-01

Full Text Available The ongoing climate warming has been reported to affect a broad range of organisms, and mountain ecosystems are considered to be particularly sensitive because they are limited by low temperatures. Meteorological data show an increased temperature for the alpine areas at Dovrefjell, Norway, causing a prolonged growing season and increased temperature sum. As part of the worldwide project Global Observation Research Initiative in Alpine Environments (GLORIA, the short-term changes in vascular plant species richness, species composition of lichen and vascular plant communities, and abundance of single species were studied at four summits representing an altitudinal gradient from the low alpine to the high alpine zone. During the period from 2001 to 2008, an increase in species richness at the lowest summit, as well as a change in the composition of vascular plant communities, was found at the two lowest summits. The results also indicate an increase in abundance of some shrubs and graminoids and a decline in the cover of some species of lichens at the lowest summit. These changes are in accordance with climate induced changes reported in other studies, but other causes for the observed vegetation changes, in particular changes in grazing and trampling pressure, cannot be ruled out.

Sandy beaches of the United States are some of the most popular tourist and recreational destinations. Coastal property constitutes some of the most valuable real estate in the country. Beaches are an ephemeral environment between water and land with unique and fragile natural ecosystems that have evolved in equilibrium with the ever-changing winds, waves, and water levels. Beachfront lands are the site of intense residential and commercial development even though they are highly vulnerable to several natural hazards, including marine inundation, flooding and drainage problems, effects of storms, sea-level rise, and coastal erosion. Because the U.S. population continues to shift toward the coast where valuable coastal property is vulnerable to erosion, the U.S. Geological Survey (USGS) is conducting a national assessment of coastal change. One aspect of this effort, the National Assessment of Shoreline Change, uses shoreline position as a proxy for coastal change because shoreline position is one of the most commonly monitored indicators of environmental change (for example, Fletcher, 1992; Dolan and others, 1991; Douglas and others, 1998; Galgano and others, 1998). Additionally, the National Research Council (1990) recommended the use of historical shoreline analysis in the absence of a widely accepted model of shoreline change.

Changing Consumption, Changing Consumers: An Analysis of Changing Food Consumption in Southern Italy in the Mid-twentieth Century

Directory of Open Access Journals (Sweden)

Ailhlin Jane Clark

2008-11-01

Full Text Available Italy’s “Economic Miracle” is often perceived as a time of change in living conditions as accelerating economic development led to more affluent lifestyles. Such changes are thought to have been reflected in what people ate and how they thought about food. While the post-World War Period has been identified as a time of radical improvements in living conditions and expectations, we can question the assumption that this was a one-way, sudden process whereby new consumer ideals simply superseded previously held values and behaviours. This paper identifies the impact of these changes on food consumption in the Amalfi Coast in the period 1945-1960. These changes may have influenced the homes in which people lived, what they did during leisure time, and what they ate, on an everyday level. It is clear, however, that pre-existing socio-economic conditions, and geographical and cultural factors, shaped both the extent to which new patterns of consumerism were adopted and the ways in which new behaviours and attitudes were worked into daily life in the area. Using information drawn from interviews conducted with inhabitants of the Amalfi Coast, this paper explores changing patterns of food consumption by assessing how food habits and traditions were directly influenced by the physical landscape, and this framed the reception of new ideas, as well as the ways by which new products were introduced into peoples’ lives and changed them in the process. The paper argues that the purchase and integration of consumable and durable items were not influenced solely by the physical possibility of buying something, but also by an element of local acceptance of the product and an understanding of how it might be integrated into daily life - factors that were constantly being negotiated with pre-existing socio-economic habits and wider cultural influences.

Signalling changes to individuals who show resistance to change can reduce challenging behaviour.

Bull, Leah E; Oliver, Chris; Woodcock, Kate A

2017-03-01

Several neurodevelopmental disorders are associated with resistance to change and challenging behaviours - including temper outbursts - that ensue following changes to routines, plans or expectations (here, collectively: expectations). Here, a change signalling intervention was tested for proof of concept and potential practical effectiveness. Twelve individuals with Prader-Willi syndrome participated in researcher- and caregiver-led pairing of a distinctive visual-verbal signal with subsequent changes to expectations. Specific expectations for a planned subset of five participants were systematically observed in minimally manipulated natural environments. Nine caregivers completed a temper outburst diary during a four week baseline period and a two week signalling evaluation period. Participants demonstrated consistently less temper outburst behaviour in the systematic observations when changes imposed to expectations were signalled, compared to when changes were not signalled. Four of the nine participants whose caregivers completed the behaviour diary demonstrated reliable reductions in temper outbursts between baseline and signalling evaluation. An active control group for the present initial evaluation of the signalling strategy using evidence from caregiver behaviour diaries was outside the scope of the present pilot study. Thus, findings cannot support the clinical efficacy of the present signalling approach. Proof of concept evidence that reliable pairing of a distinctive cue with a subsequent change to expectation can reduce associated challenging behaviour is provided. Data provide additional support for the importance of specific practical steps in further evaluations of the change signalling approach. Copyright © 2016 Elsevier Ltd. All rights reserved.

The present article deals with the potential impact of structural changes and changes in hospital control or ownership on the employment contracts of the physicians concerned. While taking the applicable jurisdiction into consideration, the author examines the options of assigning new responsibilities or decreasing compensation opportunities, amending or even terminating employment contracts, outsourcing hospital-related services, or allowing physicians in the future to provide these services at their own risk. Furthermore, the article outlines the change in employer in various "change of control" scenarios such as in the case of hospital privatisation.

Changes in Arctic and Antarctic Sea Ice as a Microcosm of Global Climate Change

Science.gov (United States)

Parkinson, Claire L.

2014-01-01

Polar sea ice is a key element of the climate system and has now been monitored through satellite observations for over three and a half decades. The satellite observations reveal considerable information about polar ice and its changes since the late 1970s, including a prominent downward trend in Arctic sea ice coverage and a much lesser upward trend in Antarctic sea ice coverage, illustrative of the important fact that climate change entails spatial contrasts. The decreasing ice coverage in the Arctic corresponds well with contemporaneous Arctic warming and exhibits particularly large decreases in the summers of 2007 and 2012, influenced by both preconditioning and atmospheric conditions. The increasing ice coverage in the Antarctic is not as readily explained, but spatial differences in the Antarctic trends suggest a possible connection with atmospheric circulation changes that have perhaps been influenced by the Antarctic ozone hole. The changes in the polar ice covers and the issues surrounding those changes have many commonalities with broader climate changes and their surrounding issues, allowing the sea ice changes to be viewed in some important ways as a microcosm of global climate change.

Recent studies projecting future climate change impacts on forests mainly consider either the effects of climate change on productivity or on disturbances. However, productivity and disturbances are intrinsically linked because 1) disturbances directly affect forest productivity (e.g. via a reduction in leaf area, growing stock or resource-use efficiency), and 2) disturbance susceptibility is often coupled to a certain development phase of the forest with productivity determining the time a forest is in this specific phase of susceptibility. The objective of this paper is to provide an overview of forest productivity changes in different forest regions in Europe under climate change, and partition these changes into effects induced by climate change alone and by climate change and disturbances. We present projections of climate change impacts on forest productivity from state-of-the-art forest models that dynamically simulate forest productivity and the effects of the main European disturbance agents (fire, storm, insects), driven by the same climate scenario in seven forest case studies along a large climatic gradient throughout Europe. Our study shows that, in most cases, including disturbances in the simulations exaggerate ongoing productivity declines or cancel out productivity gains in response to climate change. In fewer cases, disturbances also increase productivity or buffer climate-change induced productivity losses, e.g. because low severity fires can alleviate resource competition and increase fertilization. Even though our results cannot simply be extrapolated to other types of forests and disturbances, we argue that it is necessary to interpret climate change-induced productivity and disturbance changes jointly to capture the full range of climate change impacts on forests and to plan adaptation measures.

Issues in evaluation of ecosystem change in response to global change

Dowlatabadi, H.; Shevliakova, E.; Kandlikar, M.

1994-12-31

Uncertainty analysis of our integrated climate assessment model has revealed the importance of obtaining better market and non-market impacts. Improving market and non-market damage assessments has necessitated advances in the theoretical and applied dimensions of the problem. The assessment of climate change impacts on ecosystems provides a severe test for the new ideas being put forward. This paper provides a brief overview of, (i) the challenges inherent in modeling ecosystem dynamics; (ii) the problem of selecting an appropriate metric of change; and, (iii) the thorny issue of how to place a monetary value on market and non-market impacts. We focus on two central issues in estimation of impacts: (i) before climate change, are the systems being impacted (both ecological and economic) in equilibrium? and (ii) how quickly do ecological and related economic systems adapt to change? In addition, we attempt to be comprehensive in laying out the magnitude of the challenge ahead.

Changing Minds about the Changing Climate: a Longitudinal Study of the Impacts of a Climate Change Curriculum on Undergraduate Student Knowledge and Attitudes.

Science.gov (United States)

Burkholder, K. C.; Mooney, S.

2016-12-01

In the fall of 2013, 24 sophomore students enrolled in a three-course Learning Community entitled "The Ethics and Science of Climate Change." This learning community was comprised of two disciplinary courses in environmental ethics and environmental science as well as a seminar course in which the students designed and delivered climate change education events in the community beyond campus. Students were surveyed prior to and upon completion of the semester using a variant of the Yale Climate Literacy Survey in order to assess their knowledge of and attitudes towards climate change. An analysis of those survey results demonstrated that the non-traditional curriculum resulted in significant improvements that extended beyond disciplinary knowledge of climate change: the student attitudes about climate change and our cultural response to the issues associated with climate change shifted as well. Finally, a third administration of the survey (n=17) plus follow up interviews with 10 of those original students conducted during the students' senior year in 2016 suggest that the changes that the students underwent as sophomores were largely retained.

As part of continuing compliance, the U.S. Environmental Protection Agency (EPA) requires the U.S. Department of Energy (DOE) to provide any change in information since the most recent compliance application. This requirement is identified in Title 40 Code of Federal Regulations (CFR), Section 194.4(b)(4), which states: 'No later than six months after the administrator issues a certification, and at least annually thereafter, the Department shall report to the Administrator, in writing, any changes in conditions or activities pertaining to the disposal system that were not required to be reported by paragraph (b)(3) of this section and that differ from information contained in the most recent compliance application.' In meeting the requirement, the DOE provides an annual report of all changes applicable under the above requirement each November. This annual report informs the EPA of changes to information in the most recent compliance application, or for this report the 1996 Compliance Certification Application (CCA). Significant planned changes must be reported to the EPA prior to implementation by the DOE. In addition, Title 40 CFR, Section 194.4(b)(3) requires that significant unplanned changes be reported to the EPA within 24 hours or ten days, depending on the severity of the activity or condition. To date, there have been no significant unplanned changes to the certification basis. Planned changes have been submitted on an individual basis. All other changes are reported annually. The period covered by this Annual Change Report includes changes that occurred between July 1, 2003, and June 30, 2004. Changes in activities or conditions are reviewed to determine if 40 CFR Section 194.4(b)(3) reporting is necessary. As indicated above, no significant unplanned changes were identified for the time period covered by this report. The enclosed tables list those items identified for reporting under 40 CFR Section 194.4(b)(4). The majority of the changes described in

Change in the family food environment is associated with positive dietary change in children

Full Text Available Abstract Background The family food environment is an important influence in the development of children’s dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1 investigate the association between the food environment at baseline and change in children’s saturated fat intake; and (2 to explore whether a change in the food environment was associated with a change in children’s saturated fat intake. Method Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment – Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children’s dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (p Results After adjustments for child and family demographics, higher levels of perceived food availability (β=-0.2 at baseline was associated with greater reduction in saturated fat intake, where as higher perceived responsibility (β=0.2, restriction (β=0.3 and pressure to eat (β=0.3 were associated with lesser change in saturated fat. An increase in nutrition knowledge (β=-0.2, perceived responsibility (β=-0.3 and restriction (β=-0.3 from baseline to week 12 were associated with greater reduction in

To test whether changes in the patient activation measure (PAM) are related to changes in health status and healthy behaviors. Data for this secondary analysis were taken from a group-randomized, controlled trial comparing a traditional health promotion program for employees with an activated consumer program and a control program. The study population included 320 employees (with and without chronic disease) from two U.S. companies: a large, integrated health care system and a national airline. Survey and biometric data were collected in Spring 2005 (baseline) and Spring 2007 (follow-up). Change in PAM was associated with changes in health behaviors at every level (1-4), especially at level 4. Changes related to overall risk score and many of its components: aerobic exercise, safety, cancer risk, stress and mental health. Other changes included frequency of eating breakfast and the likelihood of knowing about health plans and how they compare. Level 4 of patient activation is not an end-point. People are capable of continuing to make significant change within this level. Interventions should be designed to encourage movement from lower to higher levels of activation. Even people at the most activated level improve health behaviors. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Changes in continental Europe water cycle in a changing climate

Science.gov (United States)

Rouholahnejad, Elham; Schirmer, Mario; Abbaspour, Karim

2015-04-01

Changes in atmospheric water vapor content provide strong evidence that the water cycle is already responding to a warming climate. According to IPCC's last report on Climate Change (AR5), the water cycle is expected to intensify in a warmer climate as the atmosphere can hold more water vapor. This changes the frequency of precipitation extremes, increases evaporation and dry periods, and effects the water redistribution in land. This process is represented by most global climate models (GCMs) by increased summer dryness and winter wetness over large areas of continental mid to high latitudes in the Northern Hemisphere, associated with a reduction in water availability at continental scale. Observing changes in precipitation and evaporation directly and at continental scale is difficult, because most of the exchange of fresh water between the atmosphere and the surface happens the oceans. Long term precipitation records are available only from over the land and there are no measurement of evaporation or redistribution of precipitation over the land area. On the other hand, understanding the extent of climate change effects on various components of the water cycle is of strategic importance for public, private sectors, and policy makers when it comes to fresh water management. In order to better understand the extent of climate change impacts on water resources of continental Europe, we developed a distributed hydrological model of Europe at high spatial and temporal resolution using the Soil and Water Assessment Tool (SWAT). The hydrological model was calibrated for 1970 to 2006 using daily observation of streamflow and nitrate loads from 360 gauging stations across Europe. A vegetation growth routine was added to the model to better simulate evapotranspiration. The model results were calibrated with available agricultural crop yield data from other sources. As of future climate scenarios, we used the ISI-MIP project results which provides bias-corrected climate

Little is known about how optimism differs by age and changes over time, particularly among older adults. Even less is known about how changes in optimism are related to changes in physical health. We examined age differences and longitudinal changes in optimism in 9,790 older adults over a four-year period. We found an inverted U-shaped pattern between optimism and age both cross-sectionally and longitudinally, such that optimism generally increased in older adults before decreasing. Increases in optimism over a four-year period were associated with improvements in self-rated health and fewer chronic illnesses over the same time frame. The findings from the current study are consistent with changes in emotion regulation strategies employed by older adults and age-related changes in well-being. PMID:27114753

Campbell, S.; Calderazzo, J.; Changing Climates, Cmmap Education; Diversity Team

2011-12-01

We would like to talk about a multidisciplinary education and outreach program we co-direct at Colorado State University, with support from an NSF-funded STC, CMMAP, the Center for Multiscale Modeling of Atmospheric Processes. We are working to raise public literacy about climate change by providing information that is high quality, up to date, thoroughly multidisciplinary, and easy for non-specialists to understand. Our primary audiences are college-level students, their teachers, and the general public. Our motto is Climate Change is Everybody's Business. To encourage and help our faculty infuse climate-change content into their courses, we have organized some 115 talks given by as many different speakers-speakers drawn from 28 academic departments, all 8 colleges at CSU, and numerous other entities from campus, the community, and farther afield. We began with a faculty-teaching-faculty series and then broadened our attentions to the whole campus and surrounding community. Some talks have been for narrowly focused audiences such as extension agents who work on energy, but most are for more eclectic groups of students, staff, faculty, and citizens. We count heads at most events, and our current total is roughly 6,000. We have created a website (http://changingclimates.colostate.edu) that includes videotapes of many of these talks, short videos we have created, and annotated sources that we judge to be accurate, interesting, clearly written, and aimed at non-specialists, including books, articles and essays, websites, and a few items specifically for college teachers (such as syllabi). Pages of the website focus on such topics as how the climate works / how it changes; what's happening / what might happen; natural ecosystems; agriculture; impacts on people; responses from ethics, art, literature; communication; daily life; policy; energy; and-pulling all the pieces together-the big picture.

How industries change.

Science.gov (United States)

McGahan, Anita M

2004-10-01

It's fairly obvious: To make intelligent investments within your organization, you need to understand how your whole industry is changing. But such knowledge is not always easy to come by. Companies misread clues and arrive at false conclusions all the time. To truly understand where your industry is headed, you have to take a long-term, high-level look at the context in which you do business, says Boston University professor Anita McGahan. She studied a variety of businesses from a cross section of industries over a ten-year period, examining how industry structure affects business profitability and investor returns. Her research suggests that industries evolve along one of four distinct trajectories--radical, progressive, creative, and intermediating--that set boundaries on what will generate profits in a business. These four trajectories are defined by two types of threats. The first is when new, outside alternatives threaten to weaken or make obsolete core activities that have historically generated profits for an industry. The second is when an industry's core assets--its resources, knowledge, and brand capital--fail to generate value as they once did. Industries undergo radical change when core assets and core activities are both threatened with obsolescence; they experience progressive change when neither are jeopardized. Creative change occurs when core assets are under threat but core activities are stable, and intermediating change happens when core activities are threatened while core assets retain their capacity to create value. If your company's innovation strategy is not aligned with your industry's change trajectory, your plan for achieving returns on invested capital cannot succeed, McGahan says. But if you understand which path you're on, you can determine which strategies will succeed and which will backfire.

Accelerating the culture change!

Exide Electronics, a major supplier of uninterruptible power system equipment, embarked on a journey of changing a culture to improve quality, enhance customer responsiveness, and reduce costs. This case study examines the evolution of change over a period of seven years, with particular emphasis on the most recent years, 1992 through 1995. The article focuses on the Raleigh plant operations and describes how each succeeding year built on the successes and fixed the shortcomings of the prior years to accelerate the culture change, including corrective action and continuous improvement processes, organizational structures, expectations, goals, achievements, and pitfalls. The real challenge to changing the culture was structuring a dynamic approach to accelerate change! The presentation also examines how the evolutionary process itself can be created and accelerated through ongoing communication, regular feedback of progress and goals, constant evaluation and direction of the process, and measuring and paying for performance.

Change, technology and higher education: are universities capable of organisational change?

Directory of Open Access Journals (Sweden)

Stephen Marshall

2010-12-01

Full Text Available Technology and change are so closely related that the use of the word innovation seems synonymous with technology in many contexts, including that of higher education. This paper contends that university culture and existing capability constrain such innovation and to a large extent determine the nature and extent of organisational change. In the absence of strong leadership, technologies are simply used as vehicles to enable changes that are already intended or which reinforce the current identity. These contentions are supported by evidence from e-learning benchmarking activities carried out over the past five years in universities in the United States, the United Kingdom, Australia and New Zealand.

The geoscience professoriate continues to under represent women and minorities, yet the value of diversity, both for science as well as recruiting and retaining diverse students, is well known. While there are growing numbers of early career tenure-track minority faculty, low retention rates pose a challenge for sustained diversity in the professoriate. Part of this challenge is the lack of institutional support and recognition in tenure and promotion pathways for faculty who undertake broadening participation efforts. Sparks for Change is a NSF Geoscience Opportunities for Leadership in Diversity (GOLD)-funded project that aims to change departmental culture to better value and reward inclusion and broadening participation efforts. By encouraging, recognizing, and rewarding diversity, equity, and inclusion (DEI) efforts at the department level, we aim to support and retain underrepresented minority (URM) faculty, who often disproportionately undertake these efforts, and to build more inclusive environments for faculty, staff and students alike. Sparks for Change utilizes a small group theory of change, arguing that the effort of a small group of committed individuals inside the organization is the best way to overcome the institutional inertia of academic departments that makes them resistant to change. For this effort, we propose that the ideal composition of these small groups is a junior faculty URM who is interested in DEI in the geosciences, a senior member of that same department who can lend weight to efforts and is positioned to help enact department policy, and an external broadening participation expert who can share best practices and provide accountability for the group. Eleven of these small groups, representing a range of institutions, will be brought together at the Sparks for Change Institute in Boulder, CO, in September. There they will receive leadership training on adaptive, transformative, and solidarity practices, share DEI experiences and

Full Text Available Narrating the Racialization of Space in Austin, Texas and Nashville, Tennessee People of color in the United States have been obligated to move through public space in particular ways, dictated by law and social custom. Narrators create cognitive maps of movement in the city shaped by racial codes of behavior. The maps change over time as law and social custom changes. The fluidity of the maps is also influenced by status, gender, class, and skin tone. This paper examines a rich body of oral narratives co-created with African Americans from 2004 to 2014 focusing on how men and women narrate their concepts of racialized space. It moves from narratives about the larger landscape — the city — to smaller, more personal public places — the sidewalk and the store — to intimate sites of contact in the public sphere. Many of the narratives describe complex flows of controlled movement dictated by racial boundaries in the context of capitalism. The narratives form an urban ethnography of the power relations inscribed on the landscape by racializing movement in space.   Narracje o urasowieniu przestrzeni w Austin (Teksas i Nashville (Tennessee Nie-Biali w Stanach Zjednoczonych byli zmuszeni do poruszania się w przestrzeni publicznej w szczególny sposób, określony przez prawo i zwyczaj społeczny.

Abrupt climate-independent fire regime changes

Science.gov (United States)

Pausas, Juli G.; Keeley, Jon E.

2014-01-01

Wildfires have played a determining role in distribution, composition and structure of many ecosystems worldwide and climatic changes are widely considered to be a major driver of future fire regime changes. However, forecasting future climatic change induced impacts on fire regimes will require a clearer understanding of other drivers of abrupt fire regime changes. Here, we focus on evidence from different environmental and temporal settings of fire regimes changes that are not directly attributed to climatic changes. We review key cases of these abrupt fire regime changes at different spatial and temporal scales, including those directly driven (i) by fauna, (ii) by invasive plant species, and (iii) by socio-economic and policy changes. All these drivers might generate non-linear effects of landscape changes in fuel structure; that is, they generate fuel changes that can cross thresholds of landscape continuity, and thus drastically change fire activity. Although climatic changes might contribute to some of these changes, there are also many instances that are not primarily linked to climatic shifts. Understanding the mechanism driving fire regime changes should contribute to our ability to better assess future fire regimes.

Climate Change Conceptual Change: Scientific Information Can Transform Attitudes.

Science.gov (United States)

Ranney, Michael Andrew; Clark, Dav

2016-01-01

Of this article's seven experiments, the first five demonstrate that virtually no Americans know the basic global warming mechanism. Fortunately, Experiments 2-5 found that 2-45 min of physical-chemical climate instruction durably increased such understandings. This mechanistic learning, or merely receiving seven highly germane statistical facts (Experiment 6), also increased climate-change acceptance-across the liberal-conservative spectrum. However, Experiment 7's misleading statistics decreased such acceptance (and dramatically, knowledge-confidence). These readily available attitudinal and conceptual changes through scientific information disconfirm what we term "stasis theory"--which some researchers and many laypeople varyingly maintain. Stasis theory subsumes the claim that informing people (particularly Americans) about climate science may be largely futile or even counterproductive--a view that appears historically naïve, suffers from range restrictions (e.g., near-zero mechanistic knowledge), and/or misinterprets some polarization and (noncausal) correlational data. Our studies evidenced no polarizations. Finally, we introduce HowGlobalWarmingWorks.org--a website designed to directly enhance public "climate-change cognition."

The current consensus on climatic change in Canada is briefly summarized, noting the results of modelling of the effects of a doubling of atmospheric CO 2 , the nonuniformity of climate change across the country, the uncertainties in local responses to change, and the general agreement that 2-4 degrees of warming will occur for each doubling of CO 2 . Canadian government response includes programs aimed at reducing the uncertainties in the scientific understanding of climate change and in the socio-economic response to such change. Canadian climate change programs include participation in large-scale experiments on such topics as heat transport in the ocean, and sources and sinks of greenhouse gases; development of next-generation climate models; studying the social and economic effects of climate change in the Great Lakes Basin and Mackenzie River Basin; investigation of paleoclimates; and analysis of climate data for long-term trends

Full Text Available Language can change and develop by itself slowly. Language can change and development because of adaptation of development and pattern change and system of society life, such as level of education, social, culture and technology mastery. Language change and development can occur internally and externally. In this article the changes internally and language development will be reviewed by looking through the study of historical change and development language based on the history of its development. While changes in external and development will be explored through the study of Sociolinguistics by examining and looking at changes and developments that language is influenced by socio-cultural factors that occur in society. Changes internally initially occurred in the behavior of speakers in their everyday lives to adjust to each other, and followed by a tendency to innovate in groups of people who are already familiar, then followed by other changes in sequence, which ultimately makes a language different each other, although originally derived from a single language family. Changes in the external language change and language development is caused by the contact of a language with other languages, where humans as social beings who have been cultured either interconnected or inter-ethnic nations in the world in a country.

Renal transplantation (RTx) is considered the treatment of choice for end-stage renal disease (ESRD) given its association with lower mortality, and improved overall quality of life and psychological functioning compared to dialysis. However, much less is known about which factors underlie these psychological improvements across RTx. Goal theory suggests that experienced disturbances in important goals are related to lower psychological functioning. This study aimed to (1) identify the most disturbed and most important goals for patients before RTx, (2) to examine changes in goal disturbance and goal importance pre/post-RTx, and (3) to examine whether changes in goal disturbance are associated with changes in psychological distress over time, and whether this relationship is mediated by changes in perceived control. In this longitudinal study, 220 patients completed questionnaires before and after RTx, including questionnaires to assess goals (GOALS questionnaire), psychological distress (GHQ-12), and perceived control (Mastery scale). End-stage renal disease affected both general and disease-specific goals. Approximately 30% of the patients indicated to experience high or very high disturbance before transplantation. Goal disturbance generally decreased significantly pre- to post-RTx, whereas goal importance did not change significantly pre- to post-RTx. No mediation effect of perceived control was found. Instead, both changes in goal disturbance and perceived control showed independent effects on changes in distress. Intervention strategies targeting attainable and realistic goal setting, and perceived control in RTx recipients who do not benefit optimally from RTx, might enhance psychological functioning in this population. Statement of contribution What is already known on this subject? Kidney transplantation improves patients' psychological functioning. Experienced disturbances in important life goals are related to lower psychological functioning in chronic

Surface water change as a significant contributor to global evapotranspiration change

Science.gov (United States)

Zhan, S.; Song, C.

2017-12-01

Water comprises a critical component of global/regional hydrological and biogeochemical cycles and is essential to all organisms including humans. In the past several decades, climate change has intensified the hydrological cycle, with significant implications for ecosystem services and feedback to regional and global climate. Evapotranspiration (ET) as a linking mechanism between land surface and atmosphere is central to the water cycle and an excellent indicator of the intensity of water cycle. Knowledge of the temporal changes of ET is crucial for accurately estimating global or regional water budgets and better understanding climate and hydrological interactions. While studies have examined changes in global ET, they were conducted using a constant land and surface water (SW) area. However, as many studies have found that global SW is very dynamic and their surface areas have generally been increasing since the 1980s. The conversion from land to water and vice versa significantly changes the local ET since water bodies evaporate at a rate that can be much higher than that of the land. Here, we quantify the global changes in ET caused by such land-water conversion using remotely-sensed SW area and various ET and potential ET products. New SW and lost SW between circa-1985 and circa-2015 were derived from remote sensing and were used to modify the local ET estimates. We found an increase in ET in all continents as consistent with the net increase in SW area. The increasing SW area lead to a global increase in ET by 30.38 ± 5.28 km3/yr. This is a significant contribution when compared to the 92.95 km3/yr/yr increase in ET between 1982-1997 and 103.43 km3/yr/yr decrease between 1998-2008 by Jung et al., (2010) assuming a constant SW. The results enhance our understanding of the water fluxes between the land and atmosphere and supplement land water budget estimates. We conclude that changes in SW lead to a significant change in global ET that cannot be neglected in

Land-use change may exacerbate climate change impacts on water resources in the Ganges basin

Tsarouchi, Gina; Buytaert, Wouter

2018-02-01

Quantifying how land-use change and climate change affect water resources is a challenge in hydrological science. This work aims to quantify how future projections of land-use and climate change might affect the hydrological response of the Upper Ganges river basin in northern India, which experiences monsoon flooding almost every year. Three different sets of modelling experiments were run using the Joint UK Land Environment Simulator (JULES) land surface model (LSM) and covering the period 2000-2035: in the first set, only climate change is taken into account, and JULES was driven by the CMIP5 (Coupled Model Intercomparison Project Phase 5) outputs of 21 models, under two representative concentration pathways (RCP4.5 and RCP8.5), whilst land use was held fixed at the year 2010. In the second set, only land-use change is taken into account, and JULES was driven by a time series of 15 future land-use pathways, based on Landsat satellite imagery and the Markov chain simulation, whilst the meteorological boundary conditions were held fixed at years 2000-2005. In the third set, both climate change and land-use change were taken into consideration, as the CMIP5 model outputs were used in conjunction with the 15 future land-use pathways to force JULES. Variations in hydrological variables (stream flow, evapotranspiration and soil moisture) are calculated during the simulation period. Significant changes in the near-future (years 2030-2035) hydrologic fluxes arise under future land-cover and climate change scenarios pointing towards a severe increase in high extremes of flow: the multi-model mean of the 95th percentile of streamflow (Q5) is projected to increase by 63 % under the combined land-use and climate change high emissions scenario (RCP8.5). The changes in all examined hydrological components are greater in the combined land-use and climate change experiment. Results are further presented in a water resources context, aiming to address potential implications of

Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. Clinical Relevance: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.

Conflicts between increasing irrigated agricultural area, commercial crops, shifting cultivation and ever increasing domestic and industrial demand has already been a cause of tension in the society over water in the Ganga River Basin, India. For the development of sustainable water resource strategies, it is essential to establish interaction between landuse changes and local hydrology through proper assessment. Precisely, seeing how change in each LULC affects hydrologic regimes, or conversely evaluating which LULC shall be appropriate for the local hydrological regime can help decision makers to incorporate in the policy instruments. In this study, we assess hydrologic regimes of the Ganga River basin with landuse change. Catchment hydrologic responses were simulated using Soil and Water Assessment Tool (SWAT). Meteorological data from IMD of 0.25°×0.25° spatial resolution were taken as the climate inputs. Simulated stream flow was compared at different gauge stations distributed across the Gang basin and its tributaries. Urbanization was the topmost contributor to the increase in surface runoff and water yield. While, increased irrigation demands was the dominant contributor to the water consumption and also added to the increased evapotranspiration. In addition scenarios have been generated to study the impact of landuse change on various components of hydrology including groundwater recharge, with different cropping patterns and increased irrigation efficiency to determine various mitigation strategies that can be adopted. This study can be important tool in quantifying the changes in hydrological components in response to changes made in landuse in especially basins undergoing rapid commercialization. This shall provide substantive information to the decision makers required to develop ameliorative strategies. Keywords: Landuse and Landcover change, Hydrologic model, Soil Water Assessment Tool (SWAT), Urbanization, Ganga River, Watershed hydrology.

Sustained change blindness to incremental scene rotation: a dissociation between explicit change detection and visual memory.

Science.gov (United States)

Hollingworth, Andrew; Henderson, John M

2004-07-01

In a change detection paradigm, the global orientation of a natural scene was incrementally changed in 1 degree intervals. In Experiments 1 and 2, participants demonstrated sustained change blindness to incremental rotation, often coming to consider a significantly different scene viewpoint as an unchanged continuation of the original view. Experiment 3 showed that participants who failed to detect the incremental rotation nevertheless reliably detected a single-step rotation back to the initial view. Together, these results demonstrate an important dissociation between explicit change detection and visual memory. Following a change, visual memory is updated to reflect the changed state of the environment, even if the change was not detected.

Climate change, conflict and health.

Science.gov (United States)

Bowles, Devin C; Butler, Colin D; Morisetti, Neil

2015-10-01

Future climate change is predicted to diminish essential natural resource availability in many regions and perhaps globally. The resulting scarcity of water, food and livelihoods could lead to increasingly desperate populations that challenge governments, enhancing the risk of intra- and interstate conflict. Defence establishments and some political scientists view climate change as a potential threat to peace. While the medical literature increasingly recognises climate change as a fundamental health risk, the dimension of climate change-associated conflict has so far received little attention, despite its profound health implications. Many analysts link climate change with a heightened risk of conflict via causal pathways which involve diminishing or changing resource availability. Plausible consequences include: increased frequency of civil conflict in developing countries; terrorism, asymmetric warfare, state failure; and major regional conflicts. The medical understanding of these threats is inadequate, given the scale of health implications. The medical and public health communities have often been reluctant to interpret conflict as a health issue. However, at times, medical workers have proven powerful and effective peace advocates, most notably with regard to nuclear disarmament. The public is more motivated to mitigate climate change when it is framed as a health issue. Improved medical understanding of the association between climate change and conflict could strengthen mitigation efforts and increase cooperation to cope with the climate change that is now inevitable. © The Royal Society of Medicine.

Healthy freshwater ecosystems are a critical component of the world's economy, with a critical role in maintaining public health, inland biological diversity, and overall quality of life. Globally, our climate is changing, with air temperature and precipitation regimes deviating significantly from historical patterns. Healthy freshwater ecosystems are a critical component of the world's economy, with a critical role in maintaining public health, inland biological diversity, and overall quality of life. Globally, our climate is changing, with air temperature and precipitation regimes deviating significantly from historical patterns. Changes anticipated with climate change in the future are likely to have a profound effect on inland aquatic ecosystems through diverse pathways, including changes in water quality. In this brief article, we present an initial discussion of several of the water quality responses that can be anticipated to occur within inland water bodies with climate change and how those changes are likely to impact fishes.

Carpet is a textile structure that composed of three components: warp (stuffer and chain warp), weft and pile yarns. These textile products are used for areas which will stand up to the use of home, hotel, work place etc. Furthermore, the capable of carpets are related to it’s especially pile performance during use in various areas. During usage, carpets made from various type of raw materials of pile yarn also acts differently that these differentiate determines carpet performance, as well.This study was focused on the compression and resilience behaviour of carpet composed of 100% viscose and 100% acrylic pile yarns and blended pile yarns of blend ratios, 80%/20%, 50%/50% and 20%/80% viscose/acrylic. During the yarn production process, all spinning conditions were kept constant in order to eliminate the yarn production parameters. Five different types of wilton face to face carpet samples were produced from these yarns at the same pile height and pile density on Van de Wiele carpet weaving machine at 110 picks/min machine speed and 1/1 V carpet construction. Compressibility properties of carpets were examined whether blend ratio was statistically significant on carpet resilience or not. The behaviour of pile yarns under pressure is important that leads to understand the growth characteristic which is exposed to decrease and increase loadings during usage of carpet made from these yarns. Results indicated that blend ratio of pile yarns have significance effect on compression behaviour of carpet samples.

New Zealand Freshwater Management: Changing Policy for a Changing World

Science.gov (United States)

Rouse, H. L.; Norton, N.

2014-12-01

Fresh water is essential to New Zealand's economic, environmental, cultural and social well-being. In line with global trends, New Zealand's freshwater resources are under pressure from increased abstraction and changes in land-use which contribute contaminants to our freshwater systems. Recent central government policy reform introduces greater national direction and guidance, to bring about a step-change in freshwater management. An existing national policy for freshwater management introduced in 2011 requires regional authorities to produce freshwater management plans containing clear freshwater objectives (measurable statements about the desired environmental state for water bodies) and associated limits to resource use (such as environmental flows and quantity allocation limits, and loads of contaminants to be discharged). These plans must integrate water quantity and quality management, consider climate change, and incorporate tangata whenua (New Zealand māori) roles and interests. In recent (2014) national policy amendments, the regional authorities are also required to implement national 'bottom-line' standards for certain attributes of the system to be managed; undertake accounting for all water takes and all sources of contaminants; and to develop and implement their plans in a collaborative way with communities. This rapid change in national policy has necessitated a new way of working for authorities tasked with implementation; many obstacles lie in their path. The scientific methods required to help set water quantity limits are well established, but water quality methods are less so. Collaborative processes have well documented benefits but also raise many challenges, particularly for the communication of complex and often uncertain scientific information. This paper provides background on the national policy changes and offers some early lessons learned by the regional authorities implementing collaborative freshwater management in New Zealand.

Phase-change related epigenetic and physiological changes in Pinus radiata D. Don.

Science.gov (United States)

Fraga, Mario F; Cañal, Maria Jesús; Rodríguez, Roberto

2002-08-01

DNA methylation and polyamine levels were analysed before and after Pinus radiata D. Don. phase change in order to identify possible molecular and physiological phase markers. Juvenile individuals (without reproductive ability) were characterised by a degree of DNA methylation of 30-35% and a ratio of free polyamines to perchloric acid-soluble polyamine conjugates greater than 1, while mature trees (with reproductive ability) had 60% 5-methylcytosine and a ratio of free polyamines to perchloric acid-soluble polyamine conjugates of less than 1. Results obtained with trees that attained reproductive capacity during the experimental period confirmed that changes in the degree of DNA methylation and polyamine concentrations found among juvenile and mature states come about immediately after the phase change. We suggest that both indicators may be associated with the loss of morphogenic ability during ageing, particularly after phase change, through a number of molecular interactions, which are subsequently discussed.

Land change monitoring, assessment, and projection (LCMAP) revolutionizes land cover and land change research

Science.gov (United States)

Young, Steven

2017-05-02

When nature and humanity change Earth’s landscapes - through flood or fire, public policy, natural resources management, or economic development - the results are often dramatic and lasting.Wildfires can reshape ecosystems. Hurricanes with names like Sandy or Katrina will howl for days while altering the landscape for years. One growing season in the evolution of drought-resistant genetics can transform semiarid landscapes into farm fields.In the past, valuable land cover maps created for understanding the effects of those events - whether changes in wildlife habitat, water-quality impacts, or the role land use and land cover play in affecting weather and climate - came out at best every 5 to 7 years. Those high quality, high resolution maps were good, but users always craved more: even higher quality data, additional land cover and land change variables, more detailed legends, and most importantly, more frequent land change information.Now a bold new initiative called Land Change Monitoring, Assessment, and Projection (LCMAP) promises to fulfill that demand.Developed at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota, LCMAP provides definitive, timely information on how, why, and where the planet is changing. LCMAP’s continuous monitoring process can detect changes as they happen every day that Landsat satellites acquire clear observations. The result will be to place near real-time information in the hands of land and resource managers who need to understand the effects these changes have on landscapes.

Dimensions of organizational change

Jure Kovač

2000-01-01

Full Text Available A basic characteristic of business operations in developed economic environments is their continuous search for responses to very rapid changes in their broader and closer environment. Adjustment to the changing situation of market and technology is an inevitable challenge to every company. This means a never-ending search for and verification on the market, as well as preservation of the acquired position. The tasks connected with the company's adjustment to the requirements of the market are very complex. Due to the increasingly turbulent business environment, the management responsible for the implementation of the change process is taking on new obligations. Change management is moving away from the traditional understanding of that notion as being just a set of functions, comprising the tasks of both designing and implementing a process of changing the organization. The request to establish such an organization, which will be able to follow the extremely rapid and perpetual urge for adaptation to the requirements of the environment, is coming to the forefront.

NSB organizational changes

Science.gov (United States)

To increase its involvement in National Science Foundation (NSF) policy and program oversight, the National Science Board (NSB), which is the NSF governing body, has instituted a number of changes in its committee structure and operations.One reason for the changes, according to Roland Schmitt, senior vice president for corporate research and development at the General Electric Company and chairman of NSB, is to move away from approval of NSF awards as the primary mechanism for NSB oversight of NSF programs. By law, NSB must approve awards that are above a certain dollar value. Most awards above that limit come from only a few NSF programs. The new changes will allow NSB to review programs and projects throughout NSF earlier in the review process and to affect major program decisions when they are being made.

Detecting abrupt dynamic change based on changes in the fractal properties of spatial images

Liu, Qunqun; He, Wenping; Gu, Bin; Jiang, Yundi

2017-10-01

Many abrupt climate change events often cannot be detected timely by conventional abrupt detection methods until a few years after these events have occurred. The reason for this lag in detection is that abundant and long-term observational data are required for accurate abrupt change detection by these methods, especially for the detection of a regime shift. So, these methods cannot help us understand and forecast the evolution of the climate system in a timely manner. Obviously, spatial images, generated by a coupled spatiotemporal dynamical model, contain more information about a dynamic system than a single time series, and we find that spatial images show the fractal properties. The fractal properties of spatial images can be quantitatively characterized by the Hurst exponent, which can be estimated by two-dimensional detrended fluctuation analysis (TD-DFA). Based on this, TD-DFA is used to detect an abrupt dynamic change of a coupled spatiotemporal model. The results show that the TD-DFA method can effectively detect abrupt parameter changes in the coupled model by monitoring the changing in the fractal properties of spatial images. The present method provides a new way for abrupt dynamic change detection, which can achieve timely and efficient abrupt change detection results.

SECULAR GROWTH AND MATURATION CHANGES IN HUNGARY IN RELATION TO SOCIOECONOMIC AND DEMOGRAPHIC CHANGES.

2016-03-01

This paper analyses the secular changes in the body development patterns of Hungarian children between the 1910s and the beginning of the 2000s in relation to socioeconomic and demographic changes in the country. Individual growth data of children were available from two national growth studies (1983-86, 2003-06), while sample-size weighted means of children's body dimensions were collected through regional studies between the 1920s and 1970s. Gross domestic product, Gini index, life expectancy at birth and under-5 mortality rate were used to assess the changes in economic status, income inequalities of the society and the population's general health status, respectively. Secular changes in food consumption habits were also examined. The positive Hungarian secular changes in socioeconomic status were associated with a continuous increase in children's body dimensions. The negative socioeconomic changes reflected only in wartime and post-war periods of children's growth, and the considerable socioeconomic changes at the beginning of the 1990s did not appear to influence the positive trend in children's growth. The positive secular trend in stature and body mass did not level off at the beginning of the 2000s: the socioeconomic conditions that support optimal growth and maturation could improve in Hungary.

Operational compliance engineers review all changes as part of a change control process. Each change, permanent or temporary, is required to undergo an intricate review process to ensure that the benefits associated with the change outweigh the risk. For permanent changes, it is necessary to ensure that the proposed design meets the nuclear safety requirements, conforms to the licensing requirements and complies with regulatory requirements. In addition, during installation of the permanent change and prior to in-service, a configuration management process is in place to align the change with operating and maintenance documents.

Cracking the code of change.

Science.gov (United States)

Beer, M; Nohria, N

2000-01-01

Today's fast-paced economy demands that businesses change or die. But few companies manage corporate transformations as well as they would like. The brutal fact is that about 70% of all change initiatives fail. In this article, authors Michael Beer and Nitin Nohria describe two archetypes--or theories--of corporate transformation that may help executives crack the code of change. Theory E is change based on economic value: shareholder value is the only legitimate measure of success, and change often involves heavy use of economic incentives, layoffs, downsizing, and restructuring. Theory O is change based on organizational capability: the goal is to build and strengthen corporate culture. Most companies focus purely on one theory or the other, or haphazardly use a mix of both, the authors say. Combining E and O is directionally correct, they contend, but it requires a careful, conscious integration plan. Beer and Nohria present the examples of two companies, Scott Paper and Champion International, that used a purely E or purely O strategy to create change--and met with limited levels of success. They contrast those corporate transformations with that of UK-based retailer ASDA, which has successfully embraced the paradox between the opposing theories of change and integrated E and O. The lesson from ASDA? To thrive and adapt in the new economy, companies must make sure the E and O theories of business change are in sync at their own organizations.

Projected hydrologic changes in monsoon-dominated Himalaya Mountain basins with changing climate and deforestation

Neupane, Ram P.; White, Joseph D.; Alexander, Sara E.

2015-06-01

In mountain headwaters, climate and land use changes affect short and long term site water budgets with resultant impacts on landslide risk, hydropower generation, and sustainable agriculture. To project hydrologic change associated with climate and land use changes in the Himalaya Mountains, we used the Soil and Water Assessment Tool (SWAT) calibrated for the Tamor and Seti River basins located at eastern and western margins of Nepal. Future climate change was modeled using averaged temperature and precipitation for 2080 derived from Special Report on Emission Scenarios (SRES) (B1, A1B and A2) of 16 global circulation models (GCMs). Land use change was modeled spatially and included expansion of (1) agricultural land, (2) grassland, and (3) human settlement area that were produced by considering existing land use with projected changes associated with viability of elevation and slope characteristics of the basins capable of supporting different land use type. From these simulations, higher annual stream discharge was found for all GCM-derived scenarios compared to a baseline simulation with maximum increases of 13 and 8% in SRES-A2 and SRES-A1B for the Tamor and Seti basins, respectively. On seasonal basis, we assessed higher precipitation during monsoon season in all scenarios that corresponded with higher stream discharge of 72 and 68% for Tamor and Seti basins, respectively. This effect appears to be geographically important with higher influence in the eastern Tamor basin potentially due to longer and stronger monsoonal period of that region. However, we projected minimal changes in stream discharge for the land use scenarios potentially due to higher water transmission to groundwater reservoirs associated with fractures of the Himalaya Mountains rather than changes in surface runoff. However, when combined the effects of climate and land use changes, discharge was moderately increased indicating counteracting mechanisms of hydrologic yield in these mountains

Smooth random change point models.

Science.gov (United States)

van den Hout, Ardo; Muniz-Terrera, Graciela; Matthews, Fiona E

2011-03-15

Change point models are used to describe processes over time that show a change in direction. An example of such a process is cognitive ability, where a decline a few years before death is sometimes observed. A broken-stick model consists of two linear parts and a breakpoint where the two lines intersect. Alternatively, models can be formulated that imply a smooth change between the two linear parts. Change point models can be extended by adding random effects to account for variability between subjects. A new smooth change point model is introduced and examples are presented that show how change point models can be estimated using functions in R for mixed-effects models. The Bayesian inference using WinBUGS is also discussed. The methods are illustrated using data from a population-based longitudinal study of ageing, the Cambridge City over 75 Cohort Study. The aim is to identify how many years before death individuals experience a change in the rate of decline of their cognitive ability. Copyright © 2010 John Wiley & Sons, Ltd.

Marked climate change has been forecast for regions in high latitudes by global climate models presented by the Intergovernmental Panel on Climate Change. Observations and reports of significant alterations to the natural environment of Canada's north have been reported by Inuit and other indigenous peoples using their traditional ecological knowledge as a reference. Global climate change appears to be the cause for the changes noted. Many aspects of climate change need to be addressed, such as research, outreach, impacts, adaptations and international negotiations. Based on the strong partnership that had been developed between the Inuit and four federal agencies, three territorial governments and four indigenous people's organizations in support of the Northern Contaminants Program, Inuit are now seeking a partnership with the federal government to address the issues mentioned above concerning climate change. refs., 1 tab.

Attribution of projected changes in summertime US ozone and PM2.5 concentrations to global changes

A. Guenther

2009-02-01

Full Text Available The impact that changes in future climate, anthropogenic US emissions, background tropospheric composition, and land-use have on summertime regional US ozone and PM2.5 concentrations is examined through a matrix of downscaled regional air quality simulations, where each set of simulations was conducted for five months of July climatology, using the Community Multi-scale Air Quality (CMAQ model. Projected regional scale changes in meteorology due to climate change under the Intergovernmental Panel on Climate Change (IPCC A2 scenario are derived through the downscaling of Parallel Climate Model (PCM output with the MM5 meteorological model. Future chemical boundary conditions are obtained through downscaling of MOZART-2 (Model for Ozone and Related Chemical Tracers, version 2.4 global chemical model simulations based on the IPCC Special Report on Emissions Scenarios (SRES A2 emissions scenario. Projected changes in US anthropogenic emissions are estimated using the EPA Economic Growth Analysis System (EGAS, and changes in land-use are projected using data from the Community Land Model (CLM and the Spatially Explicit Regional Growth Model (SERGOM. For July conditions, changes in chemical boundary conditions are found to have the largest impact (+5 ppbv on average daily maximum 8-h (DM8H ozone. Changes in US anthropogenic emissions are projected to increase average DM8H ozone by +3 ppbv. Land-use changes are projected to have a significant influence on regional air quality due to the impact these changes have on biogenic hydrocarbon emissions. When climate changes and land-use changes are considered simultaneously, the average DM8H ozone decreases due to a reduction in biogenic VOC emissions (−2.6 ppbv. Changes in average 24-h (A24-h PM2.5 concentrations are dominated by projected changes in anthropogenic emissions (+3 μg m−3, while changes in chemical boundary conditions have a negligible effect. On average, climate change reduces A24-h PM2

In the face of accelerating climate change and the parlous state of its politics, despair is tempting. This paper analyses two manifestations of despair about climate change related to (1) the inefficacy of personal emissions reductions, and (2) the inability to make a difference to climate change through personal emissions reductions. On the back of an analysis of despair as a loss of hope, the paper argues that the judgements grounding each form of despair are unsound. The paper concludes w...

Purpose - The sustainability of the Japanese healthcare system is in question because the government has had a huge fiscal debt. Despite an enormous effort to cut the deficit, our healthcare expenditure is increasing every year because of the rapidly aging population. One of the solutions for this problem is to improve the productivity of healthcare. The purpose of this paper is to determine the factors that change surgeons' productivity in one year. Design/methodology/approach - The authors collected data of all surgical procedures performed at Teikyo University Hospital from April 1 through September 30 in 2014 and 2015, and computed the surgeons' Malmquist index (MI), efficiency change (EC) and technical change (TC) using non-radial and non-oriented Malmquist model under the constant returns-to-scale assumptions. The authors then divided the surgeons into two groups; one whose productivity progressed and the other whose productivity regressed. These two groups were compared to identify factors that may influence their MI. Findings - The only significant difference between the two groups was ECs (p productivity change. The best way to improve surgeons' productivity may be to enhance their efficiency regardless of their surgical volume and personal backgrounds.

The present work shows the existence of systematic individual differences in change blindness. It can be concluded that the sensitivity for changes is a trait. That is, persons differ in their ability to detect changes, independent from the situation or the measurement method. Moreover, there are two explanations for individual differences in change blindness: a) capacity differences in visual selective attention that may be influenced by top-down activated attention helping to focus attentio...

Managing change in nuclear utilities

International Nuclear Information System (INIS)

2001-07-01

The nuclear power industry has undergone change since inception, but never so much as now. The rewards for proactively changing in anticipation of emerging demands are great, but the cost of failure is also great. Today nuclear plants are being shut down by socio-political and economic processes. The survival of the technology as a clean energy source for the future depends on the demonstration of long term safety to the public, protection of the environment, and economic superiority to competing energy sources. The overriding influence on these factors is strong management of the business with effective regulation. In particular it is necessary for both utility and regulator to believe that enhancing safety is part of being successful. This publication has been developed for all levels of management who are developing and implementing changes within their areas of responsibility. The safety conscious, continuous improvement, management culture, which has proven successful in today's nuclear business, has taken time to develop. Many utilities have difficulty sustaining this culture during the transitions that are intrinsic to change. Properly managed however, changes can enhance nuclear safety, plant reliability and cost competitiveness, from the design stage to decommissioning. Change has no respect for timing and regardless of the level of experience managers may have in its management, large scale change is confronting every nuclear utility world wide. These take the form of government policy changes, open market demands, privatization with the demand for increased shareholder returns, regulatory and social pressures, and economic and political transition. The danger from such issues for the nuclear company executive and the regulator is that they are powerful distractions, particularly for those executives who are not experienced in the unique managerial requirements of the nuclear business.

Attitudes and Attitude Change.

Science.gov (United States)

Albarracin, Dolores; Shavitt, Sharon

2018-01-04

This review covers research on attitudes and attitude change published between 2010 and 2017. We characterize this period as one of significant progress toward an understanding of how attitudes form and change in three critical contexts. The first context is the person, as attitudes change in connection to values, general goals, language, emotions, and human development. The second context is social relationships, which link attitude change to the communicator of persuasive messages, social media, and culture. The third context is sociohistorical and highlights the influence of unique events, including sociopolitical, economic, and climatic occurrences. In conclusion, many important recent findings reflect the fact that holism, with a focus on situating attitudes within their personal, social, and historical contexts, has become the zeitgeist of attitude research during this period.

Attitudes and attitude change remain core topics of contemporary social psychology. This selective review emphasizes work published from 2005 to 2009. It addresses constructionist and stable-entity conceptualizations of attitude, the distinction between implicit and explicit measures of attitude, and implications of the foregoing for attitude change. Associative and propositional processes in attitude change are considered at a general level and in relation to evaluative conditioning. The role of bodily states and physical perceptions in attitude change is reviewed. This is followed by an integrative perspective on processing models of persuasion and the consideration of meta-cognitions in persuasion. Finally, effects of attitudes on information processing, social memory, and behavior are highlighted. Core themes cutting across the areas reviewed are attempts at integrative theorizing bringing together formerly disparate phenomena and viewpoints.

Landscape changes have greater effects than climate changes on six insect pests in China.

Zhao, Zihua; Sandhu, Hardev S; Ouyang, Fang; Ge, Feng

2016-06-01

In recent years, global changes are the major causes of frequent, widespread outbreaks of pests in mosaic landscapes, which have received substantial attention worldwide. We collected data on global changes (landscape and climate) and economic damage caused by six main insect pests during 1951-2010 in China. Landscape changes had significant effects on all six insect pests. Pest damage increased significantly with increasing arable land area in agricultural landscapes. However, climate changes had no effect on damage caused by pests, except for the rice leaf roller (Cnaphalocrocis medinalis Guenee) and armyworm (Mythimna separate (Walker)), which caused less damage to crops with increasing mean temperature. Our results indicate that there is slight evidence of possible offset effects of climate changes on the increasing damage from these two agricultural pests. Landscape changes have caused serious outbreaks of several species, which suggests the possibility of the use of landscape design for the control of pest populations through habitat rearrangement. Landscape manipulation may be used as a green method to achieve sustainable pest management with minimal use of insecticides and herbicides.

Climate change and food security

Science.gov (United States)

Gregory, P.J; Ingram, J.S.I; Brklacich, M

2005-01-01

Dynamic interactions between and within the biogeophysical and human environments lead to the production, processing, distribution, preparation and consumption of food, resulting in food systems that underpin food security. Food systems encompass food availability (production, distribution and exchange), food access (affordability, allocation and preference) and food utilization (nutritional and societal values and safety), so that food security is, therefore, diminished when food systems are stressed. Such stresses may be induced by a range of factors in addition to climate change and/or other agents of environmental change (e.g. conflict, HIV/AIDS) and may be particularly severe when these factors act in combination. Urbanization and globalization are causing rapid changes to food systems. Climate change may affect food systems in several ways ranging from direct effects on crop production (e.g. changes in rainfall leading to drought or flooding, or warmer or cooler temperatures leading to changes in the length of growing season), to changes in markets, food prices and supply chain infrastructure. The relative importance of climate change for food security differs between regions. For example, in southern Africa, climate is among the most frequently cited drivers of food insecurity because it acts both as an underlying, ongoing issue and as a short-lived shock. The low ability to cope with shocks and to mitigate long-term stresses means that coping strategies that might be available in other regions are unavailable or inappropriate. In other regions, though, such as parts of the Indo-Gangetic Plain of India, other drivers, such as labour issues and the availability and quality of ground water for irrigation, rank higher than the direct effects of climate change as factors influencing food security. Because of the multiple socio-economic and bio-physical factors affecting food systems and hence food security, the capacity to adapt food systems to reduce their

Annual Change Report 2006/2007

International Nuclear Information System (INIS)

2007-01-01

As part of continuing compliance, the U.S. Environmental Protection Agency (EPA) requires the U.S. Department of Energy (DOE) to provide information on any change in conditions or activities pertaining to the disposal system since the most recent compliance application. This requirement is identified in Title 40 Code of Federal Regulations (CFR), Section 194.4(b)(4), which states: 'No later than six months after the administrator issues a certification, and at least annually thereafter, the Department shall report to the Administrator, in writing, any changes in conditions or activities pertaining to the disposal system that were not required to be reported by paragraph (b)(3) of this section and that differ from information contained in the most recent compliance application.' In meeting the requirement, the DOE provides an annual report each November of all applicable changes under the above requirement. This annual report informs the EPA of changes to information in the most recent compliance recertification (the 2004 Compliance Recertification). Significant planned changes must be reported to the EPA prior to implementation by the DOE. In addition, Title 40 CFR, Section 194.4(b)(3) requires that significant unplanned changes be reported to the EPA within 24 hours or ten days, depending on the severity of the activity or condition. To date, there have been no significant unplanned changes to the certification basis. Planned changes have been submitted on an individual basis. All other changes are reported annually. Changes in activities or conditions are reviewed to determine if 40 CFR Section 194.4(b)(3) reporting is necessary. As indicated above, no significant unplanned changes were identified for the time period covered by this report. The enclosed tables list those items identified for reporting under 40 CFR Section 194.4(b)(4). The majority of the items described in this report are inspections, reports, and modifications to written plans and procedures for

Changes of benthic fauna in the Kattegat - An indication of climate change at mid-latitudes?

Science.gov (United States)

Göransson, Peter

2017-07-01

Several predictions point to changes in the marine benthic macrofauna associated with climate change, but so far only a few and minor changes have been reported. This study relates observed changes in the species composition to climate change by looking on the past decades in the Kattegat between Denmark and Sweden. A reduction of the total number species and a reduction of species with a northern range parallel to an increase of species with a southern range have been observed. The most likely explanation of the changes is the increase in temperature of the bottom water. Increased temperature could change the species distributions but also decrease primary production which impacts recruitment and growth. Hypoxia and bottom trawling could also act synergistic in this process. A sparse occurrence of previously encountered Arctic-Boreal species and critical foundation species, which gives the area its special character, suggests a change in biodiversity and might therefore be designated as early warning signals of a warmer climate. The northern fauna below the halocline with limited capacity of dispersal and low reproduction potential, can be considered as sensitive with low adaptive capacity to climate change. Therefore, not only tropical and high-latitude species, but also benthos on deep bottoms at mid-latitudes, could be vulnerable to warming. As many species live at the edge of their range in the Kattegat, and also are dependent of distant recruitment, large scale changes will probably be detected here at an early stage. It is important to protect relatively undisturbed reference areas in the Kattegat for future studies, but also for preserving a large number of ecosystem services, biotopes, habitats, and fish species.

Biological diversity or biodiversity is crucial for ecological stability including regulation of climate change, recreational and medicinal use; and scientific advancement. Kenya like other developing countries, especially, those in Sub-Saharan Africa, will continue to depend greatly on her biodiversity for present and future development. This important resource must, therefore be conserved. This chapter presents an overview of Kenya's biodiversity; its importance and initiatives being undertaken for its conservation; and in detail, explores issues of climate change and biodiversity, concentrating on impacts of climate change

Incrementally Detecting Change Types of Spatial Area Object: A Hierarchical Matching Method Considering Change Process

Directory of Open Access Journals (Sweden)

Yanhui Wang

2018-01-01

Full Text Available Detecting and extracting the change types of spatial area objects can track area objects’ spatiotemporal change pattern and provide the change backtracking mechanism for incrementally updating spatial datasets. To respond to the problems of high complexity of detection methods, high redundancy rate of detection factors, and the low automation degree during incrementally update process, we take into account the change process of area objects in an integrated way and propose a hierarchical matching method to detect the nine types of changes of area objects, while minimizing the complexity of the algorithm and the redundancy rate of detection factors. We illustrate in details the identification, extraction, and database entry of change types, and how we achieve a close connection and organic coupling of incremental information extraction and object type-of-change detection so as to characterize the whole change process. The experimental results show that this method can successfully detect incremental information about area objects in practical applications, with the overall accuracy reaching above 90%, which is much higher than the existing weighted matching method, making it quite feasible and applicable. It helps establish the corresponding relation between new-version and old-version objects, and facilitate the linked update processing and quality control of spatial data.

Forestry Canada's perspectives on climate change

1990-01-01

The impacts of climatic change on Canada's forestry sector are discussed, in the context of major research priorities relating to forecasting climate, forecasting forest responses, monitoring changes, mitigating effects, and understanding the forest carbon balance. There are five major concerns that affect policy decisions: effects of climatic change on forests; adaptation to climate change; impacts of changing crops on forestry; changing forestry values in changing sociological settings; and international implications of the changing climate. A scientific program to respond to climate change issues is required, and should include the following concentrations of research effort. Planning requires projections of likely future climates, and efforts should concern relations between pre-historic climates and forest ecosystems and integrating data into predictive models. Forecasting of response of forests should include tree physiology, factors controlling reforestation, variations in forest trees, effects of pollutants, damage to forests, and forest decline

Leading change: a concept analysis.

To report an analysis of the concept of leading change. Nurses have been called to lead change to advance the health of individuals, populations, and systems. Conceptual clarity about leading change in the context of nursing and healthcare systems provides an empirical direction for future research and theory development that can advance the science of leadership studies in nursing. Concept analysis. CINAHL, PubMed, PsycINFO, Psychology and Behavioral Sciences Collection, Health Business Elite and Business Source Premier databases were searched using the terms: leading change, transformation, reform, leadership and change. Literature published in English from 2001 - 2015 in the fields of nursing, medicine, organizational studies, business, education, psychology or sociology were included. Walker and Avant's method was used to identify descriptions, antecedents, consequences and empirical referents of the concept. Model, related and contrary cases were developed. Five defining attributes of leading change were identified: (a) individual and collective leadership; (b) operational support; (c) fostering relationships; (d) organizational learning; and (e) balance. Antecedents were external or internal driving forces and organizational readiness. The consequences of leading change included improved organizational performance and outcomes and new organizational culture and values. A theoretical definition and conceptual model of leading change were developed. Future studies that use and test the model may contribute to the refinement of a middle-range theory to advance nursing leadership research and education. From this, empirically derived interventions that prepare and enable nurses to lead change to advance health may be realized. © 2016 John Wiley & Sons Ltd.

Change Communication: Facts and Fictions

Directory of Open Access Journals (Sweden)

Jürgen Mühlbacher

2012-11-01

Full Text Available Change communication is today seen as one of the most important tools enabling successful change processes. Unfortunately, change communication literature is mainly dominated by consultants. This leads to a high number of different checklists and lists of change communication tools, selling different concepts of consulting, most of them with a holistic, one-size-fits-all perspective. However, corporate communication in general and change communication in particular has to be seen as core competence of management. Top managers have to develop trust and communicate their vision of the future; middle managers should communicate and operationalize goals, so that employees have a sense of hope and orientation. These functions cannot easily be outsourced! What are missing in the majority of publications are empirically based tests of the effectiveness and the efficiency of change communication tools. Therefore, in order to increase the efficiency of change communication, this explorative study will offer an empirical survey of different tools and their attribution concerning informational aspects and behavioural influence in the context of a present day merger in the banking sector. Based on 39 semi-structured interviews, the results will show the different information needs of employees and managers and a lack of behavioural modifications. The current distribution of information leads to high costs and a high degree of confusion. Therefore, a kind of target group segmentation is needed to improve information flows and to develop motivation. This can be a first step to developing a new approach for change communication with a company-specific perspective on efficient change communication.

The user's influence on air change

Kvisgaard, B.; Collet, P.F.

1990-01-01

Of the various parameters deciding the air change in a building, the influence of wind and the stack effect have in particular been focused on. Concurrently, with the increase in quality of buildings and the tightening of existing buildings, the influence of the climatic parameters is reduced, and other parameters gain a greater influence on the air change. One of the parameters having a great influence on the air change in tight buildings are the users. The air change rate is greatly influenced by the users not only in naturally ventilated buildings, but also in mechanically ventilated buildings. On the basis of continuous measurement of the air change in 28 dwellings, the proportion between the total air change (air change in house with occupants) and the basic air change (air change in a sealed house) is discussed. The air change in each of the dwellings has been measured for a period of about one week during occupancy. The measuring principle applied is the method with constant concentration of tracer gas

A workshop was organised to evaluate and discuss the report 'Scientific Assessment of Climate Change (1990)' of the Intergovernmental Panel on Climate Change (IPCC). Thirty prominent Dutch experts in the field attended the workshop. The introductions and discussions held on our knowledge of climatic change as a result of the growth of the greenhouse effect caused by the emission of greenhouse gases from human actions are presented. It is concluded that the IPCC-report shows in a clear and balanced way the certainties and uncertainties in our knowledge of climate change. There is a large chance that the earth's climate will change considerably, if the policy remains unamended. 15 figs., 2 apps

It remains unclear whether changes in arterial wall inflammation are associated with subsequent changes in the rate of structural progression of atherosclerosis. In this sub-study of the dal-PLAQUE clinical trial, multi-modal imaging was performed using 18-fludeoxyglucose (FDG) positron emission tomography (PET, at 0 and 6 months) and magnetic resonance imaging (MRI, at 0 and 24 months). The primary objective was to determine whether increasing FDG uptake at 6 months predicted atherosclerosis progression on MRI at 2 years. Arterial inflammation was measured by the carotid FDG target-to-background ratio (TBR), and atherosclerotic plaque progression was defined as the percentage change in carotid mean wall area (MWA) and mean wall thickness (MWT) on MRI between baseline and 24 months. A total of 42 participants were included in this sub-study. The mean age of the population was 62.5 years, and 12 (28.6 %) were women. In participants with (vs. without) any increase in arterial inflammation over 6 months, the long-term changes in both MWT (% change MWT: 17.49 % vs. 1.74 %, p = 0.038) and MWA (% change MWA: 25.50 % vs. 3.59 %, p = 0.027) were significantly greater. Results remained significant after adjusting for clinical and biochemical covariates. Individuals with no increase in arterial inflammation over 6 months had no significant structural progression of atherosclerosis over 24 months as measured by MWT (p = 0.616) or MWA (p = 0.373). Short-term changes in arterial inflammation are associated with long-term structural atherosclerosis progression. These data support the concept that therapies that reduce arterial inflammation may attenuate or halt progression of atherosclerosis. (orig.)
