Grammatical gaps, grammatical invention and grammatical theory
No full textVogel R. Grammatical gaps, grammatical invention and grammatical theory. In: Strobel T, Weiß H, eds. Grammatical gaps: definition, typology and theory. Linguistische Berichte Sonderheft. Vol 34. Hamburg: Helmut Buske Verlag; 2023: 15-49.This paper focuses on the solutions that speakers find when they are faced with a grammatical
gap, i.e. a complication that occurs within the production of an utterance for which no conven-
tionalised solution is available to the speaker. I introduce the term ad hoc construction for
these solutions and analyse them as instances of linguistic (more specifically, grammatical)
creativity. Section 1 introduces the topic of this paper, section 2 discusses and rejects a psy-
cholinguistic account of ad hoc constructions in terms of grammatical illusions (Haider 2011)
for a kind of infinitival verbal complexes in German that have been subject to a controversy
(Reis 1979, Vogel 2009, Haider 2011, a.o.). An alternative in terms of grammatical creativity
is proposed. Section 3 sketches the concept of linguistic creativity in a more general way,
based on a neo-Saussurean conception of language. Section 4 highlights a number of insights
for the study of grammatical gaps

Desenvolvimento do botão floral de Rhododendron simsii cv. Helmut Vogel : controle ambiental e hormonal
No full textOrientador: Maria de Fatima D. Aleixo PereiraDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de BiologiaResumo:Rhododendron simsii é uma espécie ornamental, tendo uma grande importância comercial. Esta espécie apresenta dormência
do botão floral. o objetivo deste trabalho foi estudar o desenvolvimento do botão floral e o tempo médio de antese desta espécie, mais especificamente da cultivar Helmut Vogel, examinando a influência de baixas temperaturas (vernalização), fotoperíodo, ácido giberélico e cicocel, bem como estudar o
envolvimento de substâncias giberelínicas endógenas. Foi também construída uma escala, demonstrando vários estádios de desenvolvimento do botão floral, que abrange do estádio vegetativo até o floral completo. Os tratamentos com baixas temperaturas ou GA3, promoveram o desenvolvimento e a quebra da dormência do botão floral e consequentemente o tempo para antese foi diminuído. A vernalização pode ser substituída por tratamento com ácido giberélico, sendo que foi verificado que a concentração e o momento de aplicação de ácido giberélico influenciam a resposta. Em relação ao fotoperíodo, quando este apresentou influência, dias longos (DL) foi o fotoperíodo promotor. O tratamento com cicocel evidenciou o envolvimento de substâncias plantas que não foram tratadas com cicocel. O envolvimento de giberelínicas nos processos estudados, pois as plantas que
foram tratadas com cicocel demonstraram menor desenvolvimento do botão floral e atraso na antese, quando comparados com substâncias com atividade gibere],ínica foi também demonstrado através da análise cromatográfica e bioensaios de extratos de folhas de plantas logo após serem vernalizadas. Os resultados sugerem que o controle do desenvolvimento do botâo floral em Rhododendron simsii cv. Helmut Vogel, pode
ser controlado pelo tratamento de vernalização e a ação deste envolve alterações nos níveis de substâncias giberelínicasAbstract: Rhododendron simsii is a species considered ornamental and has a great commercial importance. This species presents
dormancy in its floral bud. The objective of this study was the observation of the floral bud development and the average time for the species anthesis, more specifically for the Helmut Vogel cv., through the investigation of the influences of the low temperatures (vernalization), photoperiod, gibberellic acid and cycocel, as well as studying the involvement of endogenous gibberellic substances. A scale was also built, showing several stages of the floral bud development, which comprises from the vegetative stage to the complete floral stage. The treatments with low temperatures or GA3 promoted
greater development and the breaking flower bud dormancy, and consequently the anthesis time was decreased. The vernalization
could be substituted through gibberellic acid treatment. However, it was observed that the concentration and the time of the gibberellic acid application do influence the result. Regarding the photoperiod, when it showed influence, the photoperiod promoter was the LD. The cycocel treatment proved
the influence of the gibberellinic substances in the studied processes, since the plants which were treated with cycocel showed lower floral bud development and the delay of the anthesis, when compared with control plants.ubstances wi th gibbereiiinic acti vi ty were demonstrated when extracted from piant ieaves just after they had been vernaiized. These resui ts suggest the participation of gibbereiiinic substances influencing the bud deveiopment and the breaking dormancy, speeding up the anthesis. The vernalization treatment is involved in the controi of these substancesMestradoMestre em Ciências Biológica
Unterstützung bei Arbeitshandlungen durch ein digitales adaptives Diagnose- und Trainingssystem

Dritte Transdisziplinäre Konferenz "Technische Unterstützungssysteme, die die Menschen wirklich wollen". Hamburg: Helmut-Schmidt-Universität; 2018: 391-398.The diagnostic and training system is a smart terminal developed as part of the project “Adap-tive Cognitive Training” (ACT). It identifies the cognitive action patterns established through education. Based on this individualized examination, a feedback on the cognitive structure of the work actions is given for each individual case. Each new test at the training terminal doc-uments the learning progress and is associated with an adapted (adaptive-learning-oriented) feedback. Through this system, it is possible to stimulate the learning potential of trainees and thus support teaching/learning processes in the training individualized and problem-oriented. Exemplary, we examined in a study the cognitive action structures of novices and compared them with an expert. We found significant differences between the memory structures of the expert and the novices. The expert showed task-specific cognitive structures with structured representations, whereas the novices showed faulty and functionless structures. With this di-agnostic and training system, we present a cognitive-technical approach, which is able to indi-vidualize feedback in learning processes
