Motivational Regulations Across the Stages of Change for Exercise in the General Population of Monterrey (Mexico)
2018
Few studies have examined exercise adherence in the Mexican population using self-determination theory proposals and the stages of change model. The objectives of this study were:(a) to translate and adapt the Behavioral Regulation in Exercise Questionnaire-3 (BREQ-3) to Mexican Spanish and examine its internal consistency and factorial structure (six dimensions); and (b) to analyse variations in behavioral regulations using the stages of change model. This study included 530 participants between 11 and 76 years old who lived in the metropolitan area of the city of Monterrey, Nuevo Leon, Mexico. The Mexican version of the BREQ-3 presented an acceptable six-factor model that agrees with the …
Simuloidun jäähdytyksen suppenemislause
2013
Tämä pro gradu -tutkielma käsittelee simuloitu jäähdytys -nimisen kombinatorisen optimointimenetelmän teoriaa ja käytäntöä. Esimerkiksi kuvankäsittelyssä sovelletun algoritmin ideana on löytää annetulla joukolla määritellyn reaaliarvoisen energiafunktion globaali minimikohta sallimalla - ei pelkästään energiaa vähentäviä - vaan myös energiaa kasvattavia siirtymiä lähtöjoukon alkioiden välillä. Tilastolliseen fysiikkaan analogian omaavan, Gibbsin jakauman ominaisuuksiin pohjautuvan menetelm än matemaattisena perustana toimivat epähomogeeniset Markovin ketjut, joiden suppenemista tarkastellaan Dobrushinin kontraktiokerroinmenetelmän avulla. Simuloidun jäähdytyksen suppenemislause, joka takaa …
The system of protected areas as the core element in a new vision of the Metropolitan City of Palermo
2022
Un processo di urbanizzazione può certamente essere considerato una delle più significative alterazioni antropiche del sistema ambientale in un territorio. Il presente studio vuole comprendere le caratteristiche spaziali della crescita urbana e i suoi impatti sulle componenti ambientali nella Città Metropolitana di Palermo, un'area in cui i livelli di consumo di suolo inedificato e di pregio, e le conseguenti forme di frammentazione ambientale e territoriale, rischiano di compromettere non solo il valore paesaggistico-ambientale dei territori coinvolti ma anche la loro identità. Partendo da queste premesse, questo contributo esplora il rapporto di reciprocità tra ambiente costruito e territ…
Social housing e interazione multietnica: un’ipotesi di progetto nel centro storico di Palermo
2015
Nelle città odierne il diritto alla casa è sempre più compromesso da molteplici fattori, primo fra tutti le conseguenze della crisi economica attuale, per cui si assiste ad una diminuzione drastica del livello di reddito delle famiglie. Vi sono anche altri fenomeni che ostacolano l’accesso al mercato immobiliare in specifiche aree urbane, come la gentrification o diverse dinamiche di trasformazione del contesto urbano, come si rileva nella città di Palermo. In contesti sociali sempre più multietnici e caratterizzati dalla presenza di varie categorie di users che risiedono in città per periodi brevi o in modo saltuario (lavoratori che si spostano da una città all’altra in cerca di occupazion…
Sociocoltura. La riscoperta del rapporto con la terra come "balsamo" per la società ibrida urbana
2014
What is the role of agriculture in contemporary societies? Two thousand years ago, Cicero stated that tending fields is among the noblest occupations for grown men, but our contemporary lifestyle seems to have forgotten that lesson. For a very long time, agriculture has been considered a relic of ancient times, and not to be pursued by techno-friendly citizens. However, we are experiencing a renaissance of attention and importance, as urban gardening and other innovative forms of agriculture and horticulture are spreading throughout our hyper-technological postmetropolises. These forms of crop tending are also stimulating new forms of relationships, spurring people to regain some control ov…
Urban Heat Island Monitoring and Impacts on Citizen's General Health Status in Isfahan Metropolis: A Remote Sensing and Field Survey Approach.
2020
Urban heat islands (UHIs) are one of the urban management challenges, especially in metropolises, which can affect citizens’ health and well-being. This study used a combination of remote sensing techniques with field survey to investigate systematically the effects of UHI on citizens’ health in Isfahan metropolis, Iran. For this purpose, the land surface temperature (LST) over a three-year period was monitored by Landsat-8 satellite imagery based on the split window algorithm. Then, the areas where UHI and urban cold island (UCI) phenomena occurred were identified and a general health questionnaire-28 (GHQ-28) was applied to evaluate the health status of 800 citizens in terms o…
Can the adaptive Metropolis algorithm collapse without the covariance lower bound?
2011
The Adaptive Metropolis (AM) algorithm is based on the symmetric random-walk Metropolis algorithm. The proposal distribution has the following time-dependent covariance matrix at step $n+1$ \[ S_n = Cov(X_1,...,X_n) + \epsilon I, \] that is, the sample covariance matrix of the history of the chain plus a (small) constant $\epsilon>0$ multiple of the identity matrix $I$. The lower bound on the eigenvalues of $S_n$ induced by the factor $\epsilon I$ is theoretically convenient, but practically cumbersome, as a good value for the parameter $\epsilon$ may not always be easy to choose. This article considers variants of the AM algorithm that do not explicitly bound the eigenvalues of $S_n$ away …
Planeamiento territorial sostenible: un reto para el futuro de nuestras sociedades; criterios aplicados
2016
Resumen En buena parte de los 17 objetivos de desarrollo sostenible marcados como metas de la humanidad por la ONU se deja entrever la sostenibilidad. Debido al modelo socioproductivo dominante, el único modo de avanzar hacia territorios más sostenibles que permitan alcanzar y mantener el bienestar de la población mundial, es tener presente la necesidad de planificar adecuadamente el desarrollo territorial. Este trabajo reflexiona sobre esta necesidad y avanza en la definición de los principales criterios para alcanzar la sostenibilidad territorial en las escalas regionales y locales.
Rozwój miast metropolitalnych Polski w kontekście rozwoju zrównoważonego
2020
Celem artykułu jest określenie poziomu rozwoju zrównoważonego miast metropolitalnych w Polsce w ramach trzech podstawowych wymiarów tego zjawiska. W analizie uwzględniono wymiar społeczny (w tym instytucjonalny), gospodarczy i środowiskowo-przestrzenny. Zastosowano metodę taksonomiczną, pozwalającą na porządkowanie badanych jednostek terytorialnych w sposób zhierarchizowany. Określono poziomy ich rozwoju w poszczególnych wymiarach z uwzględnieniem struktury cech, które je opisują. Zidentyfikowanie struktury cech pozwala na określenie, w jakiej odległości od idealnej struktury tych cech są badane miasta. Badania przeprowadzono w ujęciu dynamicznym, analizując cztery wybrane okresy czasowe (2…
