Effects of self-efficacy on healthy eating depends on normative support: a prospective study of long-haul truck drivers
2017
Purpose Fruit and vegetable intake (FV) is insufficient in industrialized nations and there is excess of discretionary food choices (DC; foods high in fat, sugar, and salt). Long-haul truck drivers are considered a particularly at-risk group given the limited food choices and normatively reinforced eating habits at truck rest-stops. Self-efficacy and normative support are key determinants of eating behavior yet the processes underlying their effects on behavior are not well understood. We tested the direct and interactive effects of self-efficacy and normative support on healthy eating behaviors in long-haul truck drivers in a prospective correlational study. Method Long-haul truck drivers …
KLUM@GTAP: Introducing biophysical aspects of land-use decisions into a general equilibrium model: A coupling experiment
2006
In this paper the global agricultural land use model KLUM is coupled to an extended version of the computable general equilibrium model (CGE) GTAP in order to consistently assess the integrated impacts of climate change on global cropland allocation and its implication for economic development. The methodology is innovative as it introduces dynamic economic land-use decisions based also on the biophysical aspects of land into a state-of-the-art CGE; it further allows the projection of resulting changes in cropland patterns on a spatially more explicit level. A convergence test and illustrative future simulations underpin the robustness and potentials of the coupled system. Reference simulat…
Time-delay control for stabilization of the Shapovalov mid-size firm model
2020
Control and stabilization of irregular and unstable behavior of dynamic systems (including chaotic processes) are interdisciplinary problems of interest to a variety of scientific fields and applications. Using the control methods allows improvements in forecasting the dynamics of unstable economic processes and offers opportunities for governments, central banks, and other policy makers to modify the behaviour of the economic system to achieve its best performance. One effective method for control of chaos and computation of unstable periodic orbits (UPOs) is the unstable delay feedback control (UDFC) approach, suggested by K. Pyragas. This paper proposes the application of the Pyragas' me…
The Lorenz system : hidden boundary of practical stability and the Lyapunov dimension
2020
On the example of the famous Lorenz system, the difficulties and opportunities of reliable numerical analysis of chaotic dynamical systems are discussed in this article. For the Lorenz system, the boundaries of global stability are estimated and the difficulties of numerically studying the birth of self-excited and hidden attractors, caused by the loss of global stability, are discussed. The problem of reliable numerical computation of the finite-time Lyapunov dimension along the trajectories over large time intervals is discussed. Estimating the Lyapunov dimension of attractors via the Pyragas time-delayed feedback control technique and the Leonov method is demonstrated. Taking into accoun…
Experimental and computational studies of unconventional main group compounds : stable radicals and reactive intermediates
2017
Ever since their discovery, radicals have intrigued the minds of experimental and theoretical chemists alike. While the vast majority of radicals are transient species, a large number of stable and persistent radicals are also known. This has enabled the use of radicals in different applications. For example, radicals are highly useful in chemical synthesis due to their selectivity and functional group tolerance. Detailed knowledge of the electronic structure of synthetic intermediates, both radical and non-radical, enables chemists to improve existing synthesis routes and to design completely new ones. This thesis is divided into two parts. The first part begins with an introduction to the…
An Overview on the Associations between Health Behaviors and Brain Health in Children and Adolescents with Special Reference to Diet Quality.
2020
Unhealthy diet has been associated with overweight, obesity, increased cardiometabolic risk, and recently, to impaired cognition and academic performance. The aim of this review is to provide an overview of the associations between health behaviors and cognition and academic achievement in children and adolescents under 18 years of age with a special reference to diet quality. Dietary patterns with a low consumption of fish, fruits, and vegetables, and high in fast food, sausages, and soft drinks have been linked to poor cognition and academic achievement. The studies on the associations between the high intake of saturated fat and red meat and low intake of fiber and high-fiber grain produ…
Tabletit opetuskäytössä : opettajien kokemuksia Mobiluck-hankkeesta
2013
Tableteista on muodostunut potentiaalinen vaihtoehto kouluissa käytettäväksi teknologiaksi. Tutkimuksessa haastateltiin yhteensä kahtatoista opettajaa Mobiluck- hankkeen lukioista. Tutkimusongelmana oli selvittää, miten tabletteja on hyödynnetty opetuksessa ja millaisia vaikutuksia niillä on ollut. Opettajien kokemuksien perusteella tablettien opetuskäytöstä muodostettiin pedagogisia esimerkkejä. Lisäksi kartoitettiin, miten opettajat käyttivät tablettia henkilökohtaisena välineenä, mitä hyötyä tableteista oli ja millaisia ongelmia kohdattiin. Tutkimuksessa havaittiin, että tabletti mahdollisti paikasta riippumattoman oppimisen ja opiskeltavan sisällön integroimisen autenttiseen maailmaan. …
Tabletti liikunnanopettajan työvälineenä : viiden liikunnanopettajan kokemuksia taulutietokoneen käytöstä opetustyössä
2015
Karppinen, Mauno (2015). TABLETTI LIIKUNNANOPETTAJAN TYÖVÄLINEENÄ. Viiden liikunnanopettajan kokemuksia taulutietokoneen käytöstä opetustyössä Liikuntakasvatuksen laitos, Jyväskylän yliopisto, Liikuntapedagogiikan pro gradu -tutkielma, 62 s. 1 liite. Tämän tutkimuksen tavoitteena oli kuvata yhtenäis- ja yläkoulujen liikunnanopettajien koke-muksia taulutietokoneesta eli tabletista työvälineenä. Tutkimuksessa etsittiin vastauksia seu-raaviin kysymyksiin: Onko taulutietokoneen käytöstä ollut apua liikunnan opetuksessa? Li-sääkö ja nopeuttaako taulutietokoneen käyttö liikunnanopettajan tekemiä merkintöjä oppilai-den suorituksista ja tekemisistä? Mitkä tabletin ominaisuudet ovat tärkeitä liikunn…
Effect of abrasive pretreatment on hot dried goji berry
2015
Goji (Lycium barbarum L.) is a Solanaceous deciduous shrub that grows in China, Tibet and other parts of Asia. Nowadays, goji berries are known as being very rich in nutrients with high antioxidant capacity, fact for which they were included in the novel category of “superfruits”. Goji berries contain high amounts of antioxidants, carotenoids, vitamin A and zeaxanthin. Most of goji berries produced are dried because they are very delicate fruits. Drying process improves fruit stability, since it decreases considerably the water activity of the food, reduces microbiological and enzymatic activity and minimizes physical and chemical reactions during storage. However, drying of goji berries ca…
EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE
2009
The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…
