| The aim of this study was to examine the morphometric characteristics of the infraorbital foramen of skulls of people living in modern society and in the late Byzantine period, to ascertain the symmetry or asymmetry of the two halves of the skulls by measuring the linear distance between various landmarks, to evaluate at the conformity between the infraorbital foramen and the golden ratio by calculating the ratios between these linear distances, and to set out the differences or similarities between the skulls of these different periods. It was found in the study that the morphometric characteristics of the infraorbital foramen in skulls of the modern period were 47.05 % circular, 41.17 % oval and 11.76 % atypical (semilunar and triangular) on the right,... |

| The recently examined durability-asymmetry hypothesis of Cook (1999) is re-evaluated using the diagnostic tests of time deformation proposed by Stock (1987, 1988). An application of these tests to disaggregated data on U.S. consumers’ expenditure provides further support for this hypothesis, with the findings given an economic interpretation in terms of variables evolving at differing speeds over different phases of the business cycle. Additionally, building upon the studies of Cover (1992), Karras (1996) and Rhee and Rich (1995), recent research by Arden et al. (2000) has shown the relaxation of the assumptions of linearity and symmetry typically employed in macroeconometric models to result in monetary policy having clear asymmetric effects on the... |

| Anatomical brain asymmetries are subtle and still little studied in humans. Among all the animals, humans have the most asymmetric brains Crow (2004). The language faculty and handedness are localized on the left side. The objective this paper is to verify whether the temporal lobes are anatomically different. Our sample was composed of 40 post mortem adult brains of both sexes, which were investigated at the Human Anatomy Laboratory of the Nove de Julho University Center in Sao Paulo, Brazil. The brains were fixed in a solution of 5% paraformaldehyde. Three different measurements were taken using a pachimeter (Mitutoyo) and a goniometer (Card) on both hemispheres: Ml - the length of the lateral sulcus; M2 - the distance from the lateral sulcus to the... |

| Knowledge about human skull asymmetry in normal dry specimens is useful as a parameter for medical and dentistry practice. Skull base was investigated with the objective to validate the method of indirect measurement with digital pictures and to evaluate the degree of asymmetry from human skull base in different ages. We analyzed 176 normal identified human skulls, divided by age in the following groups: Fetuses, newborn, children and adults. Measures were taken from a central point: pharyngeal tubercle and 4 lateral points: foramen ovale, foramen spinosum, carotid canal and stylomastoid foramen using digital biometry after a comparative validation with directed method performed with caliper. Results were presented as asymmetry indexes and data were... |

| This study looked at the dynamics of conditional correlations and hedging strategies in the US main cotton producing regions. A two-step procedure was utilized to model, estimate, and analyze volatility, conditional correlations, and the optimal hedge ratios using spot prices in the Delta, Southeast, Southern Plains, and the Southwest regions and the New York commodity exchanges December futures contracts. The results indicate that volatilities in most of the regions are asymmetric and persistent. The derived conditional correlations and the optimal hedging ratios are dynamic although they do not have unit root. Moreover, the changes in agricultural policies altered the dynamics of correlations and producers' hedging strategies in the Delta, Southeast,... |

| Morphological asymmetry has been described as a potential broiler welfare indicator, for interpreting the birds' ability to cope with the challenges that may affect its growth. The objective of this study was to evaluate the use of morphological asymmetry data to estimate broiler walking ability and welfare.dBroilers werefed diets supplemented or not with vitamin D. Toes were measured when birds were 42 and 49 days old using digital caliper.the left and right sides of the following four bilateral traits (tarsometatarsus length, outer toe length, mid toe length, and back toe length) were measured twice on intact alive birds by two different researcherh. Data from right and left sides were compared in the two treatments using the Student t-test, and... |

| Alstroemeria L., one of the most diverse genera of the Chilean flora and of high floricultural value, is represented by 35 species, most of them distributed between 28–38° S in the Mediterranean zone of Central Chile. There are 24 complex-forming taxa, of which 18 have conservation problems (8 are considered “endangered” and 10 as “vulnerable”). One of these complexes is Alstroemeria presliana Herb. with two subspecies: subsp. presliana and subsp. australis Bayer. Alstroemeria presliana grows in Chile and Argentina: subsp. presliana is distributed from Reserva Nacional Siete Tazas (35°27′ S, Region of Maule) to Antuco, (37°25′ S, Region of Bío-Bío), and is also found in Neuquén, Argentina; subsp. australis is endemic to the Cordillera of Nahuelbuta.

| Abstract Alstroemeria L. (Alstroemeriaceae) represents one of the most diverse genera of vascular plants in Chile. It contains approximately 54 taxa, 40 of which are endemic. The “complex” Alstroemeria magnifica is endemic to Chile, and it comprises four varieties: A. magnifica var. magenta, A. magnifica var. magnifica, A. magnifica var. sierrae, and A. magnifica var. tofoensis. It is distributed from Coquimbo to the Valparaíso Region. We analyzed karyotypes of 10 populations along its natural distribution. All the populations presented an asymmetric karyotype, with 2n = 16 chromosomes but with three different karyotypic formulae. Alstroemeria magnifica var. magnifica and A. magnifica var. sierrae presented the same karyotypic fomula, and A. magnifica var.... |

| ABSTRACT The present study was conducted to investigate the effect of hatching egg weight of broiler parent stocks on hatching results, chick performance, carcass characteristics, internal organ weights and some blood stress parameters. Eggs were divided into 3 egg weight groups (55.0 to 60.0 g (light), 60.1 to 65.0 g (medium) and 65.1 to 70.0 g (heavy)) for the experiments. After incubation, mixed-gender broiler chicks from the hatcher were placed into 27 grower pens (2x1 m) with 9 replications for 3 weight groups by using randomized block design. Each pen had 25 broiler chicks. Therefore, 225 chicks were used for each group and 675 chicks in total. The experiment was designed with nine replicates. Chi-square test, variance analysis test and Duncan... |

| This paper analyzes a game theoretic model of groundwater extraction in an asymmetric two-cell aquifer under incomplete information about the extent to which the local stock of groundwater depends on the extraction histories at nearby wells. A novel assumption is that the elevation of the bottom of the aquifer differs across, otherwise identical, cells. Asymmetry creates a strategic advantage (disadvantage) for the user in the deep (shallow) cell in “stealing” neighbor’s water. The user with a larger initial stock actually benefits from the commonality of groundwater provided that the asymmetry is not too small or too great. Assuming that the asymmetry between users is sufficiently large, better informed, non-cooperative users attain a higher joint... |

| Research on collective action and common-pool resources is extensive. However, little work has concentrated on the effect of variability in resource availability and collective action, especially in the context of asymmetric access to resources. Earlier works have demonstrated that environmental variability often leads to a reduction of collective action in the governance of shared resources. Here we assess how environmental variability may impact collective action. We performed a behavioral experiment involving an irrigation dilemma. In this dilemma participants invested first into a public fund that generated water resources for the group, which were subsequently appropriated by one participant at a time from head end to tail end. The amount of resource... |

| Tennis is a sport that requires asymmetric movements of dominat limbs and may lead to an asymmetric distribution of muscle mass. The main aim of the presented study was to determine the volume and degree of lateral asymmetry of the upper and lower limbs in youth tennis players using a bioelectrical impedance analysis. T-test was applied to find differences between the dominant and non-dominant arm and the right and left leg and thigh in four age categories. There were no significant differences between the right and left leg lean mass in the 12 and under, 14 and under and 16 and under age groups, but there were significant differences between the dominant and non-dominant arm lean mass and arm circumferences in all four age groups. All young tennis players... |

| This paper uses a gravity-like structure derived from a monopolistic competition model to measure market access among Canada, USA, Japan and EU Quad countries over the 1996-2001 period. We explore the overall asymmetry and 18 food industrial-level asymmetries of bilateral trade openness. Using actual bilateral estimates of tariffs and nontariff barriers, we investigate their role in explaining the trade reduction effect of national borders. A representative estimate of market access shows that higher asymmetries exist in USA, Canada and EU trade with Japan. Quite surprisingly, the last country is always more open than the reverse. Finally, we found that tariffs and NTBs explain a significant part of the border effects and that the NTB role is often... |
