Serial position effects in social transmission of food preference     

Juárez-Maldonado CE  Ortega-Saavedra G  Huichan-Olivares F  Gómez-Romero J  Cruz-Morales SE  Arriaga-Ramírez JC 《Learning & behavior》2006,34(4):374-378

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.  相似文献

University Efficiency: Complementariness versus Trade‐off between Teaching,Research and Administrative Activities     

Ricardo Sellers‐Rubio  Francisco J. Mas‐Ruiz  Ana B. Casado‐Díaz 《Higher Education Quarterly》2010,64(4):373-391

University managers should be aware of the importance that efficiency has for their own universities, orientating their actions towards research and teaching excellence. This study estimates teaching and research efficiency of the different departments of a university and tests the complementariness versus trade‐off between them. The results obtained show high levels of efficiency for the departments analysed, which is important for budget allocation, as one of the main challenges faced by a university is the allocation of budgets to different departments. The results also support the trade‐off between teaching efficiency and research activity, the complementariness between teaching efficiency and research efficiency, between research efficiency and time deducted from teaching, as well as the complementariness between research efficiency and administration activity.  相似文献

Physiological determinants of speciality of elite middle- and long-distance runners     

Rabadán M  Díaz V  Calderón FJ  Benito PJ  Peinado AB  Maffulli N 《Journal of sports sciences》2011,29(9):975-982

The aim of this study was to determine which physiological variables predict excellence in middle- and long-distance runners. Forty middle-distance runners (age 23 ± 4 years, body mass 67.2 ± 5.9 kg, stature 1.80 ± 0.05 m, VO(2max) 65.9 ± 4.5 ml · kg(-1) · min(-1)) and 32 long-distance runners (age 25 ± 4 years, body mass 59.8 ± 5.1 kg, stature 1.73 ± 0.06 m, VO(2max) 71.6 ± 5.0 ml · kg(-1) · min(-1)) competing at international standard performed an incremental running test to exhaustion. Expired gas analysis was performed breath-by-breath and maximum oxygen uptake (VO(2max)) and two ventilatory thresholds (VT(1) and VT(2)) were calculated. Long-distance runners presented a higher VO(2max) than middle-distance runners when expressed relative to body mass (P < 0.001, d = 1.18, 95% CI [0.68, 1.68]). At the intensities corresponding to VT(1) and VT(2), long-distance runners showed higher values for VO(2) expressed relative to body mass or %VO(2max), speed and oxygen cost of running (P < 0.05). When oxygen uptake was adjusted for body mass, differences between groups were consistent. Logistic binary regression analysis showed that VO(2max) (expressed as l · min(-1) and ml · kg(-1) · min(-1)), VO(2VT2) (expressed as ml · kg(-0.94) · min(-1)), and speed at VT(2) (v(VT2)) categorized long-distance runners. In addition, the multivariate model correctly classified 84.7% of the athletes. Thus, VO(2max), VO(2VT2), and v(VT2) discriminate between elite middle-distance and long-distance runners.  相似文献

Spelling errors in Spanish     

Francisco Valle-Arroyo 《Reading and writing》1990,2(1):83-98

The main purpose of this paper was to see whether dual-route models of spelling, developed within the context of opaque languages and supported mainly by the spelling patterns of acquired dysgraphics, could account for the misspellings of Spanish children of different educational levels. Sixty children (20 second, 20 fourth and 20 eighth graders) were dictated 216 verbal stimuli. Half of these stimuli were words and the other half were matched nonwords. The dependent variable was the number of errors made. Words were controlled for frequency, length and regularity. Results show that second graders rely heavily on phonological mediation with:

a)	a significantly higher number of errors committed in words than in nonwords;
b)	length affects accuracy, with more errors produced on longer words (or nonwords); and
c)	regular words are spelled significantly better than irregular words.

Eighth graders, on the other hand, show the complementary pattern of results and, consequently, seem to use a lexical strategy (via the graphemic output lexicon). The only deviant result in this group is a significant regularity effect, although the degree of this effect is smaller than in second graders. Fourth grade children show an intermediate pattern. A qualitative analysis (error types) also supports predictions made by the dual-route models. Some final considerations are proposed to explain the regularity effect in eighth graders and, based on the pattern of phonological errors, the possibility of a functional interdependence of both strategies of spelling.  相似文献   

The evolution of the MasAgro hubs: responsiveness and serendipity as drivers of agricultural innovation in a dynamic and heterogeneous context

ABSTRACT

Purpose: Little is known about effective ways to operationalize agricultural innovation processes. We use the MasAgro program in Mexico (which aims to increase maize and wheat productivity, profitability and sustainability), and the experiences of middle level ‘hub managers’, to understand how innovation processes occur in heterogeneous and changing contexts. Design/methodology/approach: We use a comparative case study analysis involving research tools such as documentary review, key informant interviews, focus group discussions, and reflection workshops with key actors. Findings: Our research shows how a program, that initially had a relatively narrow technology focus, evolved towards an innovation system approach. The adaptive management of such a process was in response to context-specific challenges and opportunities. In the heterogeneous context of Mexico this results in diverse ways of operationalization at the hub level, leading to different collaborating partners and technology portfolios. Practical implications: MasAgro experiences merit analysis in the light of national public efforts to transform agricultural advisory services and accommodate pluralistic agricultural extension approaches in Latin America. Such efforts need long-term coherent macro level visions, frameworks and support, while the serendipitous nature of the process requires meso-level implementers to respond and adapt to and move the innovation process forward. Originality/value: This paper contributes to the debate on how to operationalize large programs by showing that the innovation support arrangements enacted in the field should allow for diversity and have a degree of flexibility to accommodate heterogeneous demands from farmers in different contexts as well as continuous changes in the politico- institutional environment.  相似文献
