A Combined Experimental and Theoretical Study on the Magnetic Properties of a Family of Bis(μ‐phenoxido)dicopper(II) Complexes Bearing ω‐[Bis(2‐hydro…
2009
Five new neutral bis(μ-phenoxido)dicopper(II) complexes, [Cu2(μ-HL1)2]·3EtOH·H2O (1), [Cu2(μ-HL2)2]·1.65H2O (2), [Cu2(μ-HL3)2(μ-H2O)] (3), [Cu2(μ-HL4)2] (4) and [Cu2(μ-HL5)2(μ-H2O)] (5), were prepared from a family of ω-[bis(2-hydroxy-3,5-dimethylbenzyl)amino]alkan-1-ol ligands (H3L1–H3L5 derived from 2-aminoethanol, 3-aminopropanol, 4-aminobutanol, 5-aminopentanol and 6-aminohexanol, respectively) bearing a [O,N,O,O′] donor set. In complexes 3 and 5, there is also a bridging water molecule between the metallic centres. The copper(II) coordination planes of all these complexes form a roof-like structure (the bridging O atoms are located at the top of the roof). The structural differences fo…
The curvilinear effect of manufacturing outsourcing and captive-offshoring on firms' innovation: The role of temporal endurance
2019
Abstract This paper aims to contribute to the open debate in the literature on the effect of global sourcing strategies on firm performance by studying the consequences of manufacturing outsourcing and captive-offshoring for the innovation capability of the firm. We grounded our hypotheses based on the outsourcing and offshoring literature and by narrowing our focus to the effects of persisting in their adoption over time. We tested our hypotheses using data from a sample of 368 manufacturing companies listed on NASDAQ stock market. The paper provides theoretical explanations and empirical findings for the inverted U-shaped influence of keeping doing captive-offshoring on new product develo…
Commitment of independent and institutional women directors to corporate social responsibility reporting
2018
This paper examines how independent and institutional women directors on boards affect corporate social responsibility (hereafter CSR) reporting. Most of the previous empirical evidence has shown a linear association between female directors and CSR disclosure, but to the best of our knowledge, no research has investigated the individual effect of independent and institutional female directors on CSR reporting. Therefore, the analysis of how the disclosure of CSR information is affected by independent and institutional women directors in a separate way merits our attention. Thus, we posit that there is a nonlinear association, concretely quadratic, between independent and institutional fema…
Concurrent and lagged effects of counterdispositional extraversion on vitality
2020
Abstract There are two contrasting perspectives on the effects of state extraversion. One states that people benefit from behaving extraverted, regardless of their level of trait extraversion. The second entails that behaving concordant to one’s trait is natural while deviations from the trait level— counterdispositional behaviors—are effortful to maintain, leading to mental fatigue. We test the possibility that both perspectives are correct, with beneficial effects of high state extraversion showing immediately, while the depleting counterdispositional effects are delayed. Experience sampling data from 67 employees (N = 1,664), shows that extraverted behaviors are associated with high leve…
Extraversion and performance approach goal orientation : An integrative approach to personality
2019
Abstract Research shows that extraversion is unrelated to performance approach goal orientation, both at the trait- and the state-level. However, since previous studies have either focused on the trait- or the state-level, such a conclusion may be premature. Building upon the idea that acting against one’s trait consumes self-control resources, we reason that within-person deviations from one’s level of trait extraversion might negatively relate to performance approach goal orientation. Using experience sampling data from 47 employees across 10 days (N = 307), we found that deviations from one’s trait extraversion levels are associated with lower levels of performance approach goal orientat…
Aportaciones al cálculo de la latitud en la náutica española de principios del siglo XVII contenidas en el manuscrito de Diego Ramírez de Arellano &l…
2013
In 1620, was named chief pilot of the Casa de Contratación de Sevilla Diego Ramírez de Arellano, author of a manuscript entitled Reconocimiento de los estrechos de Magallanes y San Vicente, con algunas cosas curiosas de navegación. He had participated in the reconnaissance mission referred by the title of the manuscript, and in that book developed same methods and tools for a nautical understood scientifically, and even used a methodology close to modern science, as in refuting the theory about Figueiredo of the linear relationship between longitude and magnetic variation of the needle navigation. This article is based on some conclusions that can get an analysis of the manuscript. It focus…
SO2emissions and the environmental Kuznets curve: the case of Chinese provinces
2009
This paper aims at estimating the Environmental Kuznets Curve (EKC) for the sulphur dioxide (SO2) emissions in a panel of 28 Chinese provinces. First, using a fixed effects model, econometric findings reveal an N shape EKC with a turning point of 4500 yuans (index 1990). However, a Chow test reveals a break in 1995, so that the estimation of the model indicates an increasing linear relationship between GDP per capita and SO2 emissions. The previous results imply that the decrease of the Chinese sulphur dioxide emissions during 1996–1999 did not result from the ECK but from an exogenous public action.
Comment on “Determining soil erodibility for the USLE-MM rainfall erosion model by P.I.A. Kinnell”
2018
Abstract The measurements units of the USLE-MM soil erodibility factor are dependent on the exponent of the erosivity term. This circumstance prevents to compare soil erodibility values of sites differing by the value of this exponent. To overcame this problem, Kinnell (2018) suggested to relate the soil erodibility factor of the USLE-MM with that of USLE-M by a linear relationship with the objective to obtain a soil erodibility factor independent of the power of the erosivity term. The USLE-MB, which is a recently proposed model, has also a soil erodibility factor having measurement units common to USLE modelling environment. Kinnell (2018) also showed that the relationship between the pow…
Stationary–mobile phase distribution coefficient for polystyrene standards
2002
The measured shifts of the retention volume V R of polystyrene (PS) towards lower values in benzene–methanol (Bz–MeOH), and towards higher values in butanone–heptane (But–Hep) are in agreement with our theoretical model, in which both MeOH and But are adsorbed on Lichrospher. This paved way for us to model the chromatographic stationary (s)-phase as MeOH and the mobile (m)-phase as Bz–MeOH, and to calculate the distribution coefficients for PS. For But–Hep, the s-phase has been modeled as But, and the m-phase as But–Hep. A linear relation for the experimental equilibrium distribution P sm of PS is shown between the s- and m- phases in Bz–MeOH and But–Hep vs. the logarithm of the molecular m…
Muscular performances at the ankle joint in young and elderly men.
2005
The effect of aging on mechanical and electromyographic characteristics of ankle joint muscles was investigated in 11 young (mean age 24 years) and 12 elderly (mean age 77 years) males. Maximal and submaximal isometric voluntary torques were measured during ankle plantarflexion and dorsiflexion. Electromyographic activities of triceps surae and tibialis anterior muscles were recorded. The elderly group developed equal maximal dorsiflexion torques (42 vs 45 N.m, p >.05), but in plantarflexion, the elderly group was weaker (80 vs 132 N.m, p <.001) and presented a decreased twitch amplitude (11 vs 16 N.m) and lower coactivation (8% vs 15%) than that of the young adults. We established a linear…
