Single-molecule magnet properties of a monometallic dysprosium pentalene complex
2018
The pentalene-ligated dysprosium complex [(η8-Pn†)Dy(Cp*)] (1Dy) (Pn† = [1,4-(iPr3Si)2C8H4]2−) and its magnetically dilute analogue are single-molecule magnets, with energy barriers of 245 cm−1. Whilst the [Cp*]− ligand in 1Dy provides a strong axial crystal field, the overall axiality of this system is attenuated by the unusual folded structure of the [Pn†]2− ligand. peerReviewed
Synthesis of isomorphous cobalt and nickel thiocyanate coordination compounds: Effect of metals on compound properties
2019
The reaction of 2-methylpiperazine with the thiocyanate ligand and two transition metals leads to the production of two new isomorphous [ML2SCN4] where L is the 2-methylpiperazine and [M =Co (1), and Ni (2)], presenting an octahedral configuration. These compounds were characterized by single crystal X-ray crystallography, TG-DTA analysis, as well as infrared and UV-Vis spectroscopy and TG-DTA. The magnetic and antibacterial properties were also determined. Through the link with N-H···S hydrogen bonds, a global 3D network was established. The studied compounds show the metal center’s impact leading to different properties. Indeed, the first compound shows high spin orbit coupling, whereas t…
Coordination mechanisms and parent-subsidiary relationships in volatile environments: a theoretical approach
2015
Este trabajo es una reflexión sobre cómo puede influir la volatilidad del entorno local de una filial sobre los mecanismos de coordinación que estructuran las relaciones matriz-filial: centralización, formalización y socialización, en presencia de algunos factores de contingencia tales como el enfoque estratégico de la multinacional, el país de origen, la complejidad, el tamaño y la edad. De igual manera se emplea la tipología sobre las relaciones matriz-filial de Ghoshal y Nohria (1989) para valorar su aplicabilidad en entornos volátiles. A partir de los razonamientos realizados se plantean algunas proposiciones y se presenta como principal conclusión que, en entornos volátiles, las relaci…
Intensidade das relaciones matriz-filial em filiais venezuelanas de empresas multinacionais
2012
Este trabajo estudia la intensidad de las relaciones matriz-filial en filiales establecidas en Venezuela, a través del análisis de la presencia de mecanismos de coordinación y control dominantes en esas relaciones, tomando en consideración la naturaleza del entorno venezolano. Se utilizó una metodología de carácter cualitativo, basada en el estudio de casos en 41 filiales de diferentes sectores, países de origen y nivel de recursos. El análisis evidenció que la formalización es el mecanismo de coordinación y control que más se emplea en las relaciones matriz-filiales, seguida por la socialización. Igualmente se observó que son factores moderadores en el uso de los mecanismos de coordinación…
Mechanizm cenowy w powiązaniach kontraktowych z perspektywy teorii agencji. Przykład koordynacji transakcji na rynku ziemniaka między grupami produce…
2016
Kontrakty stanowią jedną z form pionowej koordynacji transakcji w agrobiznesie. Kluczowym aspektem umów jest odpowiednie motywowanie stron do właściwego działania oraz optymalny wybór kontrahentów. Może to się odbywać poprzez ustanowienie odpowiedniej formuły cenowej. Koncepcją teoretyczną umożliwiającą badanie tych problemów jest model pryncypał–agent w ramach teorii agencji. Celem głównym przeprowadzonych badań była identyfikacja powiązań kontraktowych między grupami producentów rolnych a pierwszym odbiorcą. Celem szczegółowym było rozpoznanie formuły cenowej. Przedmiotem badań były kontrakty między grupami producentów rolnych na rynku ziemniaka a pierwszym odbiorcą w 2014 r., dlatego zas…
Overexpression of G6PD as a model of robustness
2018
Introduction Frailty is a major geriatric syndrome that has been associated to oxidative stress. The antioxidant system is largely based on the reducing power of NADPH, whose levels are mainly determined by the enzyme glucose-6-phosphate dehydrogenase (G6PD). Material and methods Using old female Tg-mice overexpressing G6PD (18 to 26 months old), we measured frailty and different muscle parameters: oxidative stress, cross-sectional area (CSA), markers regulating protein synthesis, mitochondrial dynamics, and apoptosis. Results Our results show that 18–24 months old G6PD-Tg animals performed better in the motor coordination and grip strength test than the WT. We also found lower changes in b…
Cerebellar granule-cell-specific GABAAreceptors attenuate benzodiazepine-induced ataxia: evidence from α6-subunit-deficient mice
1999
Benzodiazepine- and alcohol-induced ataxias in rodents have been proposed to be affected by the gamma-aminobutyric acid type A (GABAA) receptor alpha 6 subunit, which contributes to receptors specifically expressed in cerebellar granule cells. We have studied an alpha 6 -/- mouse line for motor performance and drug sensitivity. These mice, as a result of a specific genetic lesion, carry a precise impairment at their Golgi-granule cell synapses. On motor performance tests (rotarod, horizontal wire, pole descending, staircase and swimming tests) there were no robust baseline differences in motor function or motor learning between alpha 6 -/- and alpha 6 +/+ mice. On the rotarod test, however,…
Important challenges for coordination and inter-municipal cooperation in health care services: a Delphi study
2013
Published version of an article in the journal: BMC Health Services Research. Also available from the publisher at: http://dx.doi.org/10.1186/1472-6963-13-451 Open Access Background: Demographical changes have stimulated a coordination reform in the Norwegian health care sector, creating new working practices and extending coordination within and between primary and hospital care, increasing the need for inter-municipal cooperation (IMC). This study aimed to identify challenges to coordination and IMC in the Norwegian health care sector as a basis for further theorizing and managerial advice in this growing area of research and practice. Methods. A Delphi study of consensus development was …
Trajectories of motor coordination in 4–7-years-old children: A latent growth curve analysis
2014
Introduction For being able to take part in physical activities typical to the given age, children need proficiency in several motor tasks. Gross motor coordination (MC) is a basis for executing motor tasks and for learning new movement patterns. This study aimed to identify different MC trajectories in children aged 4–7-years-old. Methods Motor coordination of children ( n = 94, mean age 6.1 ± 1.3 years at baseline) was measured at 0, 6 and 12 months by KTK-test battery [1] . To identify different MC trajectories, developmental trend of the mean score of KTK was analyzed by using a latent growth curve and growth mixture analysis. Results In general, MC developed significantly over the yea…
Can bureaucrats order public health? The case of Norway
2013
Introduction: The implementation of a new structural reform, the Coordination Reform, prioritizing a new public health agenda, was initiated to develop a more decentralized, integrated health care system in Norway in 2012. The same year, new health legislation was implemented and due to the new Public Health Act the responsibility for implementing a new public health agenda was decentralized to the local level. Historically, due to lack of funding – these issues have got low priority among local authorities. The new public health legislation reflects a shift in policy focus from treatment to illness prevention – where planning and partnership among primary end specialist health care, as wel…
