De la popularité à l’obscurité : Les rouages de la montée et du déclin de Federal Union, Inc. aux États-Unis, 1939-1945

Ce mémoire examine les fondements de la montée ainsi que du déclin de l’organisation non gouvernementale Federal Union, Inc. aux États-Unis entre 1939 et 1945. Ce regroupement, mis sur pied par Clarence K. Streit dans l’optique de faire la promotion de son projet internationaliste décrit dans son livre intitulé Union Now: A Proposal for a Federal Union of the Democracies of the North Atlantic, connut durant la Seconde Guerre mondiale un élan de popularité remarquable qui l’amena à l’avant-scène des débats sur la gestion des relations interétatiques, avant de s’essouffler rapidement, malgré l’intérêt qu’il suscita au cours de ses premières années d’existence. Dans les faits, ce phénomène, s’avéra étroitement lié au contexte historique, à l’idéologie défendue par le mouvement, de même qu’à l’organisation et à la gestion des activités de Federal Union, Inc. Ainsi, par l’étude d’un cas particulier, ce mémoire ouvre une nouvelle fenêtre sur l’internationalisme américain durant la Seconde Guerre mondiale, un champ d’études négligé par les chercheurs. Avec pour principal objectif d’offrir une réflexion articulée sur le fédéralisme mondial, une idéologie toujours très peu étudiée à ce jour par les historiens, cette étude mettra en lumière les rouages expliquant les hauts et les bas de cette ligne de pensée politique à l’époque. Ce faisant, le lecteur sera amené à repenser le mouvement internationaliste américain, traditionnellement perçu comme triomphant au cours de la guerre de 1939 à 1945. Il permettra de surcroît de réfléchir aux facteurs favorisant la transformation de la pensée politique au sein d’une société, tels que l’opinion publique et le rôle des organisations non gouvernementales ainsi que des groupes d’intérêt.

Poetry and transcendence in the A Túnica Inconsútil, of Jorge de Lima

We intend to study this text as Jorge de Lima establishes the relationship between two distinct activities, poetry and religion, for the elaboration of the A Túnica Inconsútil. In our perspective, the effective union of these two perspectives will be accomplished through the technique of surrealist collage, which makes use of the combination of disparate elements, together with the exploitation of classic tops of literature, such as the trip and the island. Join this practice the metaphysical poet's ideological project, which aims to establish the "poetry in Christ".

Tris[4,4,4-trifluoro-1-(2-thienyl)butane-1,3-dionato]aluminium(III)-tris[4,4,4-trifluoro-1-(2-thienyl)butane-1,3-dionato]iron(III) (3/1)

In the title compound, [Al(C8H4F3O2S)3]3[Fe(C8H4F3O2S)3], the metal centre is statistically occupied by AlIII and FeIII cations in a 3:1 ratio. The metal centre is within an octahedral O6 donor set defined by three chelating substituted acetoacetonate anions. The ligands are arranged around the periphery of the molecule with a mer geometry of the S atoms.

Cross-cultural differences in self-reported decision-making style and confidence

The Melbourne Decision Making Questionnaire (Mann, Burnett, Radford, & Ford, 1997) measures selfreported decision-making coping patterns. The questionnaire was administered to samples of University students in the US (N = 475), Australia (N = 262), New Zealand (N = 260), Japan (N = 359), Hong Kong (N = 281), and Taiwan (N = 414). As predicted, students from the three Western, individualistic cultures (US, Australia, and New Zealand) were more con® dent of their decision-making ability than students from the three East Asian, group-oriented cultures (Japan, Hong Kong, Taiwan). No cross-cultural differences were found in scores on decision vigilance (a careful decision-making style). However, compared with Western students, the Asian students tended to score higher on buck-passing and procrastination (avoidant styles of decision making) as well as hypervigilance (a panicky style of decision making). Japanese students scored lowest on decision self-esteem and highest on procrastination and hypervigilance. It was argued that the con¯ ict model and its attendant coping patterns is relevant for describing and comparing decision making in both Western and Asian cultures.

Merging business process models

This paper addresses the following problem: given two or more business process models, create a process model that is the union of the process models given as input. In other words, the behavior of the produced process model should encompass that of the input models. The paper describes an algorithm that produces a single configurable process model from an arbitrary collection of process models. The algorithm works by extracting the common parts of the input process models, creating a single copy of them, and appending the differences as branches of configurable connectors. This way, the merged process model is kept as small as possible, while still capturing all the behavior of the input models. Moreover, analysts are able to trace back from which original model(s) does a given element in the merged model come from. The algorithm has been prototyped and tested against process models taken from several application domains.

4-(2-hydroxyethyl)anilinium 3-carboxy-4-hydroxybenzenesulfonate monohydrate

In the structure of the title compound C8H12NO+ C7H5O6S- . H2O, from the reaction of 2-(4-aminophenyl)ethanol with 5-sulfosalicylic acid, the cations form head-to-tail hydrogen-bonded chains through C1/1(9) anilinium N+-H...O(hydroxyl} interactions while the anions also form similar but C1/1(8)-linked chains through carboxylic acid O-..O(sulfonate) interactions. The chains inter-associate through a number of N-H...O and O-H...O bridging interactions giving a two-dimensional array in the ab plane.

Guanidinium quinoline-2-carboxylate

In the structure of the guanidinium salt of quinaldic acid, CH6N3+ C10H6NO2-, the asymmetric unit contains two independent cations and anions having similar inter-species hydrogen-bonding environments which include cyclic R2/2(8), R1/2(6) and R2/1(5) associations. These and additional weak aromatic ring pi-pi interactions [minimum ring centroid separation, 3.6621(16)A] give a two-dimensional layered structure.

Isopropylaminium 2-carboxy-4, 5-dichlorobenzoate

In the structure of the 1:1 proton-transfer compound of isopropylamine with 4,5-dichlorophthalic acid, C3H10N+·C8H3Cl2O4-, the three cation H-atom donors associate with three separate carboxyl O-atom anion acceptors, giving conjoint cyclic R44(12), R44(16) hydrogen-bonding cation-anion interactions in a one-dimensional ribbon structure. In the anions, the carboxyl groups lie slightly out of the plane of the benzene ring [maximum deviations = 0.439 (1) for a carboxylic acid O atom and 0.433 (1) Å for a carboxylate O atom]. However, the syn-related proton of the carboxylic acid group forms the common short intramolecular O-HOcarboxyl hydrogen bond.

Ethane-1,2-diaminium 4,5-dichlorophthalate

In the structure of the title compound, C2H10N22+·C8H2Cl2O42-, the dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R21(7), R12(7) and R42(8) associations and extend down the c-axis direction. These ribbons inter-associate down b, giving a two-dimensional sheet structure. In the dianions, one of the carboxylate groups is essentially coplanar with the benzene ring, while the other is normal to it [C-C-C-O torsion angles = 177.67 (12) and 81.94 (17)°, respectively].

Bis[2-(2,4-dinitrobenzyl)pyridinium] biphenyl-4,4'-disulfonate

In the structure of the title compound, the salt 2(C12H10N3O4+) (C12H8O6S2)2- . 3H2O, determined at 173 K, the biphenyl-4,4'-disulfonate dianions lie across crystallographic inversion centres with the sulfonate groups interacting head-to-head through centrosymmetric cyclic bis(water)-bridged hydrogen-bonding associations [graph set R4/4(11)], forming chain structures. The 2-(2,4-dinitrobenzyl)pyridinium cations are linked to these chains through N+-H...O(water) hydrogen bonds and a two-dimensional network structure is formed through water bridges between sulfonate and 2-nitro O atoms, while the structure also has weak cation--anion pi-pi aromatic ring interactions [minimum ring centroid separation 3.8441(13)A].

2-(2,4-dinitrobenzyl)pyridinium 2-hydroxy-3,5-dinitrobenzoate

In the structure of the title compound, the salt C12H10N3O4+ C7H3N2O72-, the cations and the anions are linked by a single N+-H...O(carboxyl) hydrogen bond, the discrete cation-anion unit having no intermolecular associations other than weak cation--anion aromatic ring pi--pi interactions [ring centroid separation, 3.7320(14)A] and a number of weak inter-unit aromatic C-H...O contacts.

Guanidinium 2-phenylacetate

In the structure of CH6N3+ C8H7O2-, the guanidinium cation gives three cyclic hydrogen-bonding interactions with O acceptors of three independent phenylacetate anions, one R2/2(8) and two R1/2(6), giving one-dimensional columnar structures which extend down the 4~2~ axis in the tetragonal cell. Within these structures there are 86.5A^3^ solvent accessible voids.
