The objective of this work was to evaluate the use of the conductivity test as a means of predicting seed viability in seven Passiflora species: P. alata, P. cincinnata, P. edulis f. edulis, P. edulis f. flavicarpa, P. morifolia, P. mucronata, and P. nitida. Conductivity of non?desiccated (control), desiccated, and non?desiccated cryopreserved seeds was determined and related to their germination percentage. The obtained results suggest that the electrical conductivity test has potential as a germination predictor for P. edulis f. flavicarpa seed lots, but not for the other tested species. Index terms: Passiflora, seed cryopreservation, seed desiccation, seed viability.

My project in this paper is to provide a plausible idea of Christ’s suffering and death in terms of a theory of the human person. More specifically, I want to contrast two major theories of the person-body relation. One is dualism. Dualism is the view that a human person is composed of two substances, that is, a soul and a body, and he (strictly speaking) is identical with the soul. On the other hand, physicalism is the view that a human person is numerically identical with his biological body. I will argue that dualism is not successful in explaining Christ’s passion for some reasons. Rather, physicalism, as I shall argue, provides a better explanation of how Christ’s physical suffering and death are real just like everyone else’s, so it is philosophically and theologically more plausible than dualism.

Studies of the continuum between geographic races and species provide the clearest insights into the causes of speciation. Here we report on mate choice and hybrid viability experiments in a pair of warningly colored butterflies, Heliconius erato and Heliconius himera, that maintain their genetic integrity in the face of hybridization. Hybrid sterility and inviability have been unimportant in the early stages of speciation of these two Heliconius. We find no evidence of reduced fecundity, egg hatch, or larval survival nor increases in developmental time in three generations of hybrid crosses. Instead, speciation in this pair appears to have been catalyzed by the association of strong mating preferences with divergence in warning coloration and ecology. In mate choice experiments, matings between the two species are a tenth as likely as matings within species. F1 hybrids of both sexes mate frequently with both pure forms. However, male F1 progeny from crosses between H. himera mothers and H. erato fathers have somewhat reduced mating success. The strong barrier to gene flow provided by divergence in mate preference is probably enhanced by frequency-dependent predation against hybrids similar to the type known to occur across interracial hybrid zones of H. erato. In addition, the transition between this pair falls at the boundary between wet and dry forest, and rare hybrids may also be selected against because they are poorly adapted to either biotope. These results add to a growing body of evidence that challenge the importance of genomic incompatibilities in the earliest stages of speciation.

The purpose of the present study was to examine the relationship of harmonious and obsessive passion to perceptions of task and social cohesion in team sport athletes. Participants were 370 competitive (N=252) and recreational (N=118) athletes ranging from 18- to 28-years-old (Mage=20.20, SD=1.52) from a wide variety of team sports. Participants completed the Passion Scale (Vallerand et al., 2003) and the Group Environment Questionnaire (Carron et al., 1985). A MANOVA revealed that competitive athletes were more passionate and had higher perceptions of cohesion than did recreational athletes. Multiple regression analyses revealed a positive relationship between both harmonious and obsessive passion and both task (ATG-T, GI-T) and social (ATG-S, GI-S) cohesion. Theoretical and practical implications are discussed pertaining to the importance of harmonious and obsessive passion in athletes and perceptions of cohesion in competitive and recreational sport.

Individuals often pursue activities for which they are passionate about, and this passion is operationalized as being harmonious (an autonomous desireto engage in the activity) or obsessive (a controlled desire to engage in the activity) in nature (Vallerand et al., 2003). With regard to harmonious passion, Vallerand et al. (2003) suggests that it is fostered in environments that nurture innate needs for autonomy, competence, and relatedness. The purpose of the present study was to explore the nature of the passion-basic psychological needs (competence, autonomy, relatedness) relationship. Kinesiology students (N = 917; Mage = 18.54 SD = 1.66) completed the Passion Scale (Vallerand et al., 2003) and the Psychological Need Satisfaction in Exercise Scale (Wilson et al., 2006). Results from the SEM path analysis indicated that harmonious passion was positively related to competence (SPE = .43) and relatedness (SPE = .43) and obsessive passion was negatively related to autonomy (SPE = -.18)(CFI = .90, RMSEA = .07, SRMR = .07). Implications for exercise participation/enjoyment are discussed.
