A Lisrel Model for Country Risk Assessment
2015
As German industry is very much export-oriented, country risk assessment is a major problem in international marketing for German suppliers. The data from several country risk assessment indicator concepts were collected and put into a LISREL model to test which hypothesized relationships between the measured variables and hypothetical constructs can be empirically proved. A structural equation model will be developed to be able to test the causal relationships between the hypothetical constructs over time (multi-wave, multi-variable model).

A path analysis model of self-rated health among older people.
1999
The aim of this study was to examine the structure of self-rated health among 75-year-old men and women. The study was part of the Evergreen project, comprising all the 75-year-old residents (N = 382) of Jyväskylä, in central Finland, in 1989. The data were collected by interviews, questionnaires and laboratory examinations, focusing on different domains of health and functional capacity. Of the target group, 91.6% (119 men and 231 women) participated in the interview, and 77.2% (104 men and 191 women) took part in the clinical and laboratory examinations. Path analysis models (LISREL 8) were used to examine the structure of self-rated health. About half the participants self-rated their he…
Mobility limitations and cognitive deficits as predictors of institutionalization among community-dwelling older people.
2006
<i>Purpose:</i> Mobility limitations and cognitive disorders have often been observed as risks for institutionalization. However, their combined effects on risk of institutionalization among initially community-dwelling older people have been less well reported. <i>Design:</i> A prospective cohort study with 10-year surveillance on institutionalization. <i>Subjects:</i> Study population (n = 476) consisted of 75- and 80-year-old people who were community-dwelling, had not been diagnosed with dementia, and participated in tests on walking speed and cognitive capacity at a research centre. <i>Measures:</i> Cognitive capacity was measured with th…
Quality of Life and Barriers in the Urban Outdoor Environment in Old Age
2010
OBJECTIVES: To examine the association between barriers in the outdoor environment and perceived quality of life (QoL) in old age and to assess whether fear of moving outdoors and unmet physical activity need contribute to this association. DESIGN: Cross-sectional. SETTING: Community and research center. PARTICIPANTS: Five hundred eighty-nine, community-dwelling people aged 75 to 81 took part in face-to-face home-interviews and examinations in the research center. MEASUREMENTS: QoL was assessed using the LEIPAD questionnaire. Environmental barriers were studied based on self-reports of lack of resting places or long distances (distances), noisy traffic or dangerous crossroads (traffic), and…
Disability, physical activity, and muscle strength in older women: The women's health and aging study
1999
Abstract Objective: To study associations of motor disability, physical activity, and muscle strength in older women, in particular to investigate whether model of spiraling decrease is expressed in the data. Design: Cross-sectional analysis using data from the base-line measurements of The Women's Health and Aging Study (WHAS). Setting: Participants' homes. Participants: A total of 1,002 disabled women aged 65 years and older living in the community. Outcome Measures: Motor disability was measured by the number of self-reported difficulties in grasping, lifting 101b, walking across a small room, walking 14 mile, climbing 10 steps, and doing heavy housework. Level of physical activity was d…
Long-Term Behavioral Programming Induced by Peripuberty Stress in Rats Is Accompanied by GABAergic-Related Alterations in the Amygdala
2014
Stress during childhood and adolescence is a risk factor for psychopathology. Alterations in γ-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain, have been found following stress exposure and fear experiences and are often implicated in anxiety and mood disorders. Abnormal amygdala functioning has also been detected following stress exposure and is also implicated in anxiety and social disorders. However, the amygdala is not a unitary structure; it includes several nuclei with different functions and little is known on the potential differences the impact of early life stress may have on this system within different amygdaloid nuclei. We aimed here to evaluate pote…
Vaakakupissa vaarat ja vastuu: Julkisen palvelun median arvot sosiaalisen median alustojen paineessa
2021
Sosiaalisen median alustat ovat muovanneet media-alan prosesseja ja käytäntöjä merkittävästi. Alustayritysten toimintaa ohjaavat erilaiset arvot ja tavoitteet kuin mediaorganisaatioita, mikä aiheuttaa toimijoiden välille ristiriitaa. Toimintatavoistaan ja arvoistaan sosiaalisessa mediassa joutuvat neuvottelemaan erityisesti julkisen palvelun mediayhtiöt, joiden peruskivenä ovat julkisen palvelun arvot. Tarkastelemme tässä artikkelissa suomalaisen julkisen palvelun mediayhtiön Yleisradion alustasuhdetta laadullisen haastatteluaineiston avulla. Kysymme, miten Yleisradiossa kuvataan ja perustellaan suhdetta sosiaalisen median alustoihin ja minkälaiseen arvopuheeseen suhteen kuvaaminen kytkeyty…
The electronic substituent influence on the thermally allowed electrocyclic interconversion cyclobutene/butadiene. A MNDO study
1984
The effects of donor/acceptor substitution on the conrotatory cyclobutene/butadiene interconversion have not yet been experimentally studied. MNDO Synchronous Transit/MINIMAX calculations for all possible combinations of NH2/NH3 + 3 groups at the fissile single bond reveal very large substituent effects on the opening reactions and reverse cyclisations. Diamino(1b/2b), diammonio-(1c/2c) and amino-ammonio-substitutions (1d/2d) change the activation energy of the reference ring opening reaction (1a →2a) from 49.9 kcal/mol to 34.7, 29.8 and 26.0 kcal/mol, respectively. This rate enhancement parallels the monotone shift of the transition state pathcoordinate towards the cyclobutenes. Relative t…
