AbstractThis paper deals with the category of number in Latin, specifically with the different meanings of the plural with verbal nouns. In the first section, I establish a reference framework on the concept of number, and in particular the so-called “number anomalies”. The second part of the paper addresses the functional complexity of the category of number itself, so it presents and exemplifies the four different meanings of plural forms with verbal nouns and explains them in light of the concepts of prototype and recategorization. The third section aims to identify the factors yielding a determined plural reading; in this way, I explain the connection between some meanings of the plural and the types of events that verbal nouns describe. Lastly, in the final section, I discuss the main results of this study.

Cultural Developments

A growing number of urban interventions, such as culture-led regeneration strategies, has emerged alongside growing awareness of the concept of re-urbanization. These interventions evolve to create a holistic urban vision, with aims to promote social cohesion and strengthen local identity as opposed to traditional goals of measuring the economic impact of new cultural developments. Szczecin’s, Poland urban strategy is focused on the expansion of culture—a condition for improving the quality of life and increasing the city’s attractiveness. This article assesses the potential for re-urbanization of Szczecin’s flagship cultural developments. Questionnaire surveys and qualitative research methods were used to assess the characteristics that distinguish cultural projects in the formal, location-related, functional, and symbolic layers, as well as examining their social perception. The results show that the strength of these indicators of urbanscape identity affects how the cultural developments are assessed by the society. Semiotic coherence and functional complexity of the structures have a significant impact on the sense of identification, while their monumentality and exposure contribute to the assessment of the impact on their surroundings. A development with a firm identity, embedded in the city’s tradition not only preserves the cultural heritage of the city but also makes inhabitants feel association with the new project.

Wrong Interpretation

A targeted search for heliotropin (or piperonal) in the flower fragrance of heliotrope and in cured vanilla beans of Tahitian origin is reported. Heliotropin is not detected in the fragrance emitted by heliotrope, using dynamic headspace SBSE sampling, followed by thermal desorption and analysis by conventional GC-MS. Main constituents are anisaldehyde and benzaldehyde, which confirms previous findings. Less than one part per million of heliotropin is accurately detected in authentic Tahitian vanilla bean, in using both GC-MS and LC-MS/MS. This confirms previous observations, which had shown that 4-methoxyaromatic compounds are the characteristic elements in the flavor of Tahitian vanilla, with p-anisaldehyde as the the main aroma donator. We suggest that heliotropin was named after the discovery of piperonal by degradation of piperine, the odor of which was reminiscent of the heliotrope flower. Later, its identification in vanilla extracts was the result of either a wrong interpretation of analytical data, or, much more probably, adulterations of these extracts. As a result, heliotropin should not be cited any longer as a characteristic consituent of Tahitian vanilla.

Abstract We show by molecular analysis of behavioral and physiological mutants that the Drosophila Dmca1A calcium-channel α1 subunit is encoded by the cacophony (cac) gene and that nightblind-A and lethal(1)L13 mutations are allelic to cac with respect to an expanded array of behavioral and physiological phenotypes associated with this gene. The cacS mutant, which exhibits defects in the patterning of courtship lovesong and a newly revealed but subtle abnormality in visual physiology, is mutated such that a highly conserved phenylalanine (in one of the quasi-homologous intrapolypeptide regions called IIIS6) is replaced by isoleucine. The cacH18 mutant exhibits defects in visual physiology (including complete unresponsiveness to light in certain genetic combinations) and visually mediated behaviors; this mutant (originally nbAH18) has a stop codon in an alternative exon (within the cac ORF), which is differentially expressed in the eye. Analysis ofthe various courtship and visual phenotypes associated with this array ofcac mutants demonstrates that Dmca1A calcium channels mediate multiple, separable biological functions; these correlate in part with transcript diversity generated via alternative splicing.
