Despite the vitality and dynamism that the field of entrepreneurship has experienced in the last decade, the issue of whether it comprises an effective network of (in)formal communication linkages among the most influential scholars within the area has yet to be examined in depth. This study follows a formal selection procedure to delimit the ‘relational environment’ of the field of entrepreneurship and to analyze the existence and characterization of (in)visible college(s) based on a theoretically well-grounded framework, thus offering a comprehensive and up-to-date empirical analysis of entrepreneurship research. Based on more than a 1,000 papers published between 2005 and 2010 in seven core entrepreneurship journals and the corresponding (85,000) citations, we found that entrepreneurship is an (increasingly) autonomous, legitimate and cohesive (in)visible college, fine tuned through the increasing visibility of certain subject specialties (e.g., family business, innovation, technology and policy). Moreover, the rather dense formal links that characterize the entrepreneurship (in)visible college are accompanied by a reasonably solid network of informal relations maintained and sustained by the mobility of ‘stars’ and highly influential scholars. The limited internationalization of the entrepreneurship community, reflected in the almost total absence of non-English-speaking authors/studies/outlets, stands as a major quest for the field.
Although there is considerable consensus that Finance, Management and Marketing are ‘science’, some debate remains with regard
to whether these three areas comprise autonomous, organized and settled scientific fields of research. In this paper we aim
to explore this issue by analyzing the occurrence of citations in the top-ranked journals in the areas of Finance, Management,
and Marketing. We put forward a modified version of the model of science as a network, proposed by Klamer and Van Dalen (J
Econ Methodol 9(2):289–315, <cite>2002</cite>), and conclude that Finance is a ‘Relatively autonomous, organized and settled field of research’, whereas Management and
(to a larger extent) Marketing are relatively non-autonomous and hybrid fields of research’. Complementary analysis based
on sub-discipline rankings using the recursive methodology of Liebowitz and Palmer (J Econ Lit 22:77–88, <cite>1984</cite>) confirms the results. In conclusions we briefly discuss the pertinence of Whitley’s (The intellectual and social organization
of the sciences, <cite>1984</cite>) theory for explaining cultural differences across these sub-disciplines based on its dimensions of scholarly practices,
‘mutual dependency’ and ‘task uncertainty’.

L.) population density (PD) could be used to improve the wheat production technology in Northwestern Mexico. Tillering capacity is a characteristic of the variety. Theoretically, the recommended PD should not be modified by the variety. The objective of this study was to determine the effects of the variety (V) and PD on wheat yield and other components. A field study was carried out at the Yaqui Valley Agricultural Experimental Station, in Sonora, Mexico. It consisted of a complete factorial of five wheat varieties: Aconchi C89, Tepoca T89, Oasis F86, Altar C85, and Rayon F89, and seven PD treatments: 20, 40, 80, 160, 240, 320 and 800 thousand plants per hectare (TPPH)) in a split plot design with varieties as main plots and the PD as subplots in a complete randomized block design with five replications. For all the evaluated variables, the response to PD was different according to the variety, mainly in treatments with low PD, and as this was increased, the response turned asymptotic, with optimum PD being different for each variety. The maximum yield and the other wheat components were reached with the optimum PD, around 160 TPPH. The number of tillers per plant (TPP) always decreased with increased PD, while the harvest index (HI) was not affected by the studied factors.
A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.
