Combining war damages accounting and accounting for the natural world with social-organisational repercussions
No full textThe authors propose a critical reinterpretation of a case study embedded in the historical period of post-WWII in Southern Italy. This period is characterised by relevant socio-political and economic consequences at a global scale, and it has been scarcely investigated from a business perspective. The authors consider the connections between war damages accounting, adverse collateral events, and agricultural accounting as tools to claim for social changes. The analysis specifically concerns the damages caused to the warehouses of hemp growers in the province of Caserta (Campania region, Italy). This area was known as Terra di Lavoro (‘land of work’ (authors’ translation)) since the Middle Ages to outline the poor conditions of hemp growers. The features of the accounting analysed herein, in the light of neo-institutional theory, show how it was used as a technology for problem-solving and a potential trigger for the agrarian reform of 1950
Photosynthesis in Ranunculus asiaticus L.: characterization in two Mediterranean hybrids under fluorescent white light
No full textRanunculus asiaticus L. is a quantitative long-day species, originating from Mediterranean area, grown in cold greenhouse for cut flowers and potted plants. Flowering in ranunculus is a complex process, strongly steered by the temperature and the photoperiod. Vernalization of rehydrated tuberous roots, used as propagation material, anticipates sprouting and leaf rosette formation and flowering. It is known that the time for flowering and the sensitivity to cold treatment vary in the numerous commercial hybrids, while no information seems to be available on the influence of vernalization on the photosynthetic process.
The aim of the experiment was to investigate the influence of two hybrids, MDR (medium earliness) and MBO (early flowering), and two preparation treatments of tuberous roots, only rehydration (Control, C) and rehydration plus vernalisation (V), on photosynthesis and photochemistry and photosynthetic pigments content in plants grown in pot in growth chamber, under controlled environment.
In control plants, photosynthesis was higher in MDR-C than in MBO-C, while the maximal PSII photochemical efficiency (Fv/Fm) slightly decreased in the first hybrid. MBO-C developed more leaves and a consequent higher plant leaf area.
Compared to only rehydration, vernalization of rehydrated tuberous roots increased the number of leaves and the plant leaf area in both the hybrids. The preparation treatment did not affect photosynthetic rate while it decreased the maximal PSII photochemical efficiency (Fv/Fm) in both the hybrids. A significant interaction was found between the hybrid and the preparation treatment in the content of photosynthetic pigments, which decreased in plants from vernalized tuberous roots compared to those from only rehydrated roots in MDR, while increased with vernalization in MBO

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
From suburb to ‘glocal’ innovation hub: Troisi Park, a potential agro-social plaza to intensify the renewal value of the eastern district of Naples
No full textUrban agriculture can play a key role in achieving environmental, social and economic well-being of neighbourhoods, by activating direct and indirect services and opportunities for citizens and contributing to the requalification of neglected suburban areas of big cities. Troisi Park is one of the larger urban parks of the Metropolitan City of Naples. Accomplished in the 1980s on a brownfield area, nowadays the park is experiencing a decline period. In the framework of the H2020 FoodE project, aiming to create sustainable and resilient City/Region Food Systems, the municipality of Naples in collaboration with the Department of Agricultural Sciences of the University of Naples Federico II will bring new life and essence to this park, and in turn to the surrounding area. Through co-designing and planning activities already in progress, Troisi Park will become a ‘global but local' agro-biodiversity hub. Knowledge, nature and culture en masse will engender job opportunities for disadvantaged-people, beside a space for youths, families and people eager to have a healthy lifestyle, being concurrently part of a sustainable inclusive food system, from food production to consumption. Furthermore, the core area of the park will host a greenhouse cluster for horticultural crop production as well as small allotments to be rented to locals and for educational purposes. Owing to an active and inclusive collaboration between local schools, initiatives, the municipality and the University of Naples Federico II, creating a sustainable future for this district of the city is achievable
Photosynthesis in Ranunculus asiaticus L.: characterization in two Mediterranean hybrids under fluorescent white light
No full textRanunculus asiaticus L. is a quantitative long‐day (LD) flower species, originating from Mediterranean area. Cultivation of this crop for cut flowers has been rising during the last years.
Flowering in ranunculus is a complex process, in which the thermal history of tuberous roots and the photoperiod play crucial roles. Specifically, cold treatments of tuberous roots anticipates sprouting and leaf rosette formation, and flowering. Similarly, LD anticipates flowering, but inhibiting the meristematic activity and reducing the number of flower stems. Based on literature, no information seems to be available for ranunculus about the hormonal balance at the different phenological phases, and on the influence of vernalisation on the hormones involved in flowering, and the effects of exogenous gibberellins is controversial.
The aim of the experiment was to asses, in two hybrids of R. asiaticus, the influence of tuberous roots vernalisation on plant photosynthesis and photochemistry, gibberellic acid (GA3) and indoleacetic acid (IAA) biosynthesis, and flowering earliness and characteristics.
Plants of the hybrids MDR (medium earliness) and MBO (early flowering) (Biancheri Creations, Italy), from rehydrated tuberous roots, were grown in climatic chamber at 18°C, under white fluorescent light (PPFD 170 mol m‐2 s‐1, 16 hours), in a mixture of perlite and peat (70:30 in vol.).
In both the treatments, Control (only rehydration) and Vernalisation (exposure of rehydrated tuberous roots to 3,5 °C for 10 days), GA3 and IAA content was determined on tuberous roots at the sowing, and at the rosette stage. Light saturation curves of photosynthesis were determined at the rosette stage, while instantaneous photosynthetic rate and photochemistry, and chlorophyll content were measured at both vegetative and reproductive stages.
Results provide a useful characterization of photosynthetic performance of ranunculus during plant development. Data on the influence of corm vernalisation on the hormonal profile in tuberous roots will help the comprehension on the process of flowering in this species. These information have physiological and practical value, as cultivation of ranunculus is increasing worldwide
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
