The purpose of this research was to relate the influence of specific site suitability variables to eastern monarch butterfly migratory patterns and behavior. Elevation, temperature, precipitation, and land use data layers were overlaid to collectively consider how these variables affected the way that butterflies migrated and recolonized during the 2016/2017 migratory cycle. The variables were reclassified into layers ranking suitability as either unsuitable, suitable, or optimal with respective scores of one, three, and five. Three uninhabitable variables were identified that deemed a site unsuitable despite the influence and possible optimal suitability of the other variables. The results of this study indicated that site suitability was a large driving factor for migratory monarchs with a heavier emphasis placed on average temperature and land/cropland use. Possible displaced and sink populations were identified for further study, while the effects of agriculture, development, and climate change were considered regarding flyway connectivity and behavior.

Français. Un inventaire des ptéridophytes a été entrepris dans les forêts de la région de Tlemcen. L’inventaire de ces populations constitue une étape importante pour le développement des stratégies de conservation des ressources génétiques et de la diversité de ces populations sur l’ensemble de leur aire de distribution naturelle. Nous avons ainsi effectué le recensement et l’identification des fougères existantes dans la région de Tlemcen. Au total, plusieurs stations dont les caractéristiques écologiques diffèrent d’un site à un autre ont été prospectées, cela a permis l’identification de 26 taxons (dont 5 exceptionnellement rare). La création de réserves naturelles forestières renforcée par une protection réglementaire des espèces les plus menacées est nécessaire pour le maintien de ces communautés si particulières. English. An inventory of Pteridophyta was begun in the forests of the Tlemcen region. The inventory of these populations constitutes an important stage for the developement of the strategies of preservation of the genetic resources and the diversity of these populations on their whole area of natural distribution. We so made the inventory and the identification of the existing ferns in the region of Tlemcen. On the whole, several stations the ecological characteristics differ from a site in the other one were canvassed; they allowed the identification of 26 taxes (among which 5 exceptionally rare). The creation of forest nature reserves strengthened by a statutory protection of the most threatened species is necessary for the preservation of these particular communities.

The introduction first sets out some preliminary definitions of sex, sexuality, and gender. It then turns from the sexual part of Sexual Identities to the identity part. A great deal of confusion results from failing to distinguish between identity in the sense of a category with which one identifies (categorial identity) and identity in the sense of a set of patterns that characterize one’s cognition, emotion, and behavior (practical identity). The second section gives a brief summary of this difference. The third and fourth sections sketch the relation of the book to social constructionism and queer theory, on the one hand, and evolutionary-cognitive approaches to sex, sexuality, and gender, on the other. The fifth section outlines the value of literature in not only illustrating, but advancing a research program in sex, sexuality, and gender identity. Finally, the introduction provides an overview of the chapters in this volume.

Based on surveys of winter roost sites, the eastern migratory population of the monarch butterfly (Danaus plexippus) in North America appears to have declined in the last 20 years and this has prompted the implementation of numerous conservation strategies. However, there is little information on the survivorship of first-generation monarchs in the core area of occupancy in Texas, Oklahoma, and Louisiana where overwinter population recovery begins. The purpose of this study was to determine the survivorship of first-generation eggs to third instars at a site in north Texas and to evaluate host plant arthropods for their effect on survivorship. Survivorship to third instar averaged 13.4% and varied from 11.7% to 15.6% over three years. The host plants harbored 77 arthropod taxa, including 27 predatory taxa. Despite their abundance, neither predator abundance nor predator richness predicted monarch survival. However, host plants upon which monarchs survived often harbored higher numbers of non-predatory arthropod taxa and more individuals of non-predatory taxa. These results suggest that ecological processes may have buffered the effects of predators and improved monarch survival in our study. The creation of diverse functional arthropod communities should be considered for effective monarch conservation, particularly in southern latitudes.

Marine renewable energy is still in its infancy and poses serious challenges due to the harsh marine conditions encountered for wave or tidal installations and the survivability of devices. Geophysical and hydrodynamic initial site surveys need to be able to provide repeatable, reliable, and economical solutions. An oscillating water column wave energy converter is to be installed on the west coast of King Island, Tasmania. The location is in a high-energy nearshore environment to take advantage of sustained shoaling non-breaking waves of the Southern Ocean and required site-specific information for the deployment. We provide insight into scalable geophysical site surveys capable of capturing large amounts of data within a short time frame. This data was incorporated into a site suitability model, utilising seabed slope, sediment depth, and water depth to provide the terrain analysis needed to match deployment-specific characteristics. In addition, short-term hydrology and geotechnical work found a highly energetic seabed (near seafloor water velocities <1 m/s) with sufficient bearing capacity (6 MPa). In a highly energetic environment, care was taken to collect the relevant data needed for an assessment of critical information to an emerging technology companies primary project. This is in addition to the malleable methodology for a site suitability model that can incorporate various weighted parameters to prioritise the location for shallow wave energy sites in general.

The title compound, lithium/sodium iron(III) bis[orthomolybdate(VI)], was obtained by a solid-state reaction. The main structure units are an FeO6octahedron, a distorted MoO6octahedron and an MoO4tetrahedron sharing corners. The crystal structure is composed of infinite double MoFeO11chains along theb-axis direction linked by corner-sharing to MoO4tetrahedra so as to form Fe2Mo3O19ribbons. The cohesion between ribbonsviamixed Mo—O—Fe bridges leads to layers arranged parallel to thebcplane. Adjacent layers are linked by corners shared between MoO4tetrahedra of one layer and FeO6octahedra of the other layer. The Na+and Li+ions partially occupy the same general position, with a site-occupancy ratio of 0.631 (9):0.369 (1). A comparison is made withAFe(MoO4)2(A= Li, Na, K and Cs) structures.

This paper marks the relation between humanities education and democracy as one of mutual necessity, since the pragmatic value of each is dependent on the other to be recognizable and realizable. Such an understanding is drawn from the ideas of the American philosopher and educator John Dewey. Dewey’s system clearly reveals the nature of the stakes of the assault on the humanities; it also indicates the educational measures democratic societies should take in response. By instantiating the “conjoint communicated experience” of democracy in a public, shared space in which differences are respected, human meanings are explored, and the expansion of knowledge and experience is valued as an end in itself, the humanities classroom emerges as a site of social renewal, as well as one of resistance to illiberalism. In order to present such a site in a manner befitting Dewey’s pragmatism, a lesser-known, local example of the value of humanities education is examined in this paper: that of the International Institute in Spain, located in Madrid. Beginning with its founding as a school for girls by Boston missionaries in 1892, and through its role at the center of a network of institutions invested in progressive educational reform in Spain during the pre-civil war period, IIE stands as a testament to the continuity through renewal that defines both liberal democracy and humanities education.

Sleep, food and language are pillars of children’s healthy lives, are intertwined from birth and make up the dynamic structure of child development. These are the effects of interdependent conditions: organic, psychic and social, which involve the child and result, simultaneously, from organic and symbolic inheritances. The latter overdetermines and modulates the interaction of the child with the environment, especially with the other human who is there. This heritage will draw patterns of conduct and behavior that can often contribute to changes that compromise, to some extent, the overall development of the child. In the children’s clinic, the description of developmentdisorders, from the mildest to the most severe, includes, as a rule, food, sleep and language aspects, which suggests, then, a base triad, questioning clinicians as to the possibility of there being, more than a simple coincidence, a correlation between fundamental biological functions. If this is the case, it will be important for the clinician to appropriate this perspective, since the implication will probably determine particularities in the diagnostic and treatment procedures. In this direction, it is worth deepening and discussing the development of these functions (sleep, diet, language), seeking to clarify their constitutive correlation, the link between them.

Consumer ethnocentrism implies the consumers? orientation to the purchasing of domestic goods, disapproval of purchasing of foreign goods, and the attitude that the buyers of foreign goods are responsible for domestic economic problems and unemployment. This paper presents the results of measurement of consumer ethnocentrism in Central Serbia, five administrative districts precisely (Sumadijski, Pomoravski, Rasinski, Moravicki, and Raski). Results show the moderate level of consumer ethnocentrism, which is now higher than before economic crisis, but still at the same level as the ethnocentrism in other counties of the region (B&H, Croatia, and Montenegro). At the segment level, consumer ethnocentrism is higher among rural, older and male population. Results also display the high and statistically significant correlation between level of consumer ethnocentrism, on one side, and consumer?s preferences and behavior, on the other.
