Every Olive Tree in the Garden of Gethsemane is a suite of photographic images of each of the twenty-three olive trees in the garden. Situated at the foot of the Mount of Olives in Jerusalem, the Garden of Gethsemane is known to many as the site where Jesus and his disciples prayed the night before his crucifixion. The oldest trees in the garden date to 1092 and are recognized as some of the oldest olive trees in existence. The older trees are a living and symbolic connection to the distant past, while younger trees serve as a link to the future. The gnarled trunks seem written with the many conflicts that have been waged in an effort to control this most-contested city; a city constantly on the threshold of radical transformation.

In analysing Lester Beall's posters for the U.S. government between 1937-1941, Michael Golec demonstrates the twofold character of facts in art and design appearing even when they are applied to guarantee distinct messages. Commissioned by the governmental agencies to develop a series of posters to increase the electrification of rural farms, Beall introduces pictograms in his first series to represent electrification as “facts of the future.” Its simple forms facilitate the travelling of this facts without loss of their integrity. The same holds true for the use of photographic images for the second campaign of 1939. Following the revaluation of photography as a means for the documentation of social reality, as represented by the FSA photographers under the guidance of Roy Stryker, the medium served here as the authentication of facts. Golec holds, that Beall by reducing the complexity of the photographic images, to create a pictorial integrity of his posters, even despite of the use of a seemingly documentary medium, reinforces the ambivalent factual character of the pictures. So, paradoxically by heightening the communicative character of the design and hence stressing the idea of facts as integral realities outside of artworks, Beall's posters reveal the ambiguous character of pictorial facts creating their own specific qualities. Golec concludes, that facts in works of art and design have a twofold character resulting from their belonging to different spaces, which although meant to accomplish and address different facts, inevitably travel, overlap and bleed into each other. Thus oddly these facts refer or represent reality and simultaneously are a thing made (factum) that present and hold their own pictorial reality.

Olive trees constitute one of the largest agroindustries in the Mediterranean area, and their cultivation generates a diverse pool of biomass by-products such as olive tree pruning (OTP), olive leaves (OL), olive stone (OS), and extracted olive pomace (EOP). These lignocellulosic materials have varying compositions and potential utilization strategies within a biorefinery context. The aim of this work was to carry out an integral analysis of the aqueous extractives fraction of these biomasses. Several analytical methods were applied in order to fully characterize this fraction to varying extents: a mass closure of >80% was reached for EOP, >76% for OTP, >65% for OS, and >52% for OL. Among the compounds detected, xylooligosaccharides, mannitol, 3,4-dihydroxyphenylglycol, and hydroxytyrosol were noted as potential enhancers of the valorization of said by-products. The extraction of these compounds is expected to be more favorable for OTP, OL, and EOP, given their high extractives content, and is compatible with other utilization strategies such as the bioconversion of the lignocellulosic fraction into biofuels and bioproducts.

Wild olive trees have important potential, but, to date, the oil from wild olives has not been studied significantly, especially from an analytical point of view. In Spain, the wild olive tree is called “Acebuche” and its fruit “Acebuchina”. The objective of this work is to optimize the olive oil production process from the Acebuchina cultivar and characterize the oil, which could be marketed as healthy and functional food. A Box–Behnken experimental design with five central points was used, along with the Response Surface Methodology to obtain a mathematical experimental model. The oils from the Acebuchina cultivar meet the requirements for human consumption and have a good balance of fatty acids. In addition, the oils are rich in antioxidants and volatile compounds. The highest extraction yield, 12.0 g oil/100 g paste, was obtained at 90.0 min and the highest yield of phenolic compounds, 870.0 mg/kg, was achieved at 40.0 °C, and 90.0 min; but the maximum content of volatile compounds, 26.9 mg/kg, was obtained at 20 °C and 30.0 min. The oil yield is lower than that of commercial cultivars, but the contents of volatile and phenolic compounds is higher.

AbstractIn a recent paper by one of the authors and collaborators, motivated by the Olive Quick Decline Syndrome (OQDS) outbreak, which has been ongoing in Southern Italy since 2013, a simple epidemiological model describing this epidemic was presented. Beside the bacterium Xylella fastidiosa, the main players considered in the model are its insect vectors, Philaenus spumarius, and the host plants (olive trees and weeds) of the insects and of the bacterium. The model was based on a system of ordinary differential equations, the analysis of which provided interesting results about possible equilibria of the epidemic system and guidelines for its numerical simulations. Although the model presented there was mathematically rather simplified, its analysis has highlighted threshold parameters that could be the target of control strategies within an integrated pest management framework, not requiring the removal of the productive resource represented by the olive trees. Indeed, numerical simulations support the outcomes of the mathematical analysis, according to which the removal of a suitable amount of weed biomass (reservoir of Xylella fastidiosa) from olive orchards and surrounding areas resulted in the most efficient strategy to control the spread of the OQDS. In addition, as expected, the adoption of more resistant olive tree cultivars has been shown to be a good strategy, though less cost-effective, in controlling the pathogen. In this paper for a more realistic description and a clearer interpretation of the proposed control measures, a spatial structure of the epidemic system has been included, but, in order to keep mathematical technicalities to a minimum, only two players have been described in a dynamical way, trees and insects, while the weed biomass is taken to be a given quantity. The control measures have been introduced only on a subregion of the whole habitat, in order to contain costs of intervention. We show that such a practice can lead to the eradication of an epidemic outbreak. Numerical simulations confirm both the results of the previous paper and the theoretical results of the model with a spatial structure, though subject to regional control only.

The future of the field of entrepreneurship is bright primarily because of the many research opportunities to make a difference. However, as scholars how can we find these opportunities and choose the ones most likely to contribute to the literature? This essay introduces me-search and a special issue of research-agenda papers from leading scholars as tools for blazing new trails in entrepreneurship research. Me-search and the agenda papers point to the importance of solving a practical problem; problematizing, contextualizing, and abstracting entrepreneurship research; and using empirical theorizing to explore entrepreneurial phenomena.

Several species of the genus Phytophthora are associated with root rot and trunk cankers in olive trees (Olea europaea L.). Among them, Phytophthora megasperma has been cited as being associated with olive root rots in Greece (1). Unidentified species of Pythium and Phytophthora have also been associated with olive tree root rots in the United States. However, the status of P. megasperma and Pythium spp. as olive tree root pathogens has remained unclear. Following a 5-year period of severe drought in southern Spain, autumn-winter rainfall rates in 1996 to 1997 steadily increased in both quantity and frequency. Under these unusually wet conditions, olive trees remained waterlogged for several months. During this period, we observed foliar wilting, dieback, and death of young trees, and later found extensive root necrosis. In 46 of 49 affected plantations surveyed, P. megasperma was consistently isolated from the rotted rootlets, particularly in young (<1- to 10-year-old trees) plantations. This fungus was not detected on plant material affected by damping-off from several Spanish olive tree nurseries. The opposite situation occurred with P. irregulare. This species was not associated with rotted rootlets in the field. In contrast, it was consistently isolated from necrotic rootlets from young olive plants affected by damping-off. These plants were grown in a sand-lime-peat soil mixture under greenhouse conditions and showed foliar wilting and extensive necrosis of the root systems. Pathogenicity tests were conducted with several isolates of P. megasperma and P. irregulare on 6-month-old rooted cuttings of olive, under both weekly watering and waterlogged conditions. Under waterlogged conditions, both fungal species produced extensive root necrosis 2 weeks after inoculation that resulted in wilting of the aerial parts and rapid plant death. Waterlogged control plants remained without foliar symptoms but a low degree of root necrosis was recorded. In addition, under weekly watering conditions, plants inoculated with either species showed some degree of root rot but foliar symptoms were not evident. No differences in pathogenicity were observed within the Phytophthora or Pythium isolates. Reference: (1) H. Kouyeas and A. Chitzanidis. Ann. Inst. Phytopathol. Benaki 8:175, 1968.

The present study on olive tuberculosis commenced by isolating bacteria of the genus Pseudomonas from the soils and necrosis of collected olive trees. A total of 180 samples were used in this study: (100) rhizospheric soil samples: (60) samples at the region of Ain Témouchent and (40) at the region of Sig in western of Algeria. In total, (80) galls were collected (40) at branch level and (40) galls at olive tree leaf (level). The isolates were identified by microbiological (macroscopic and microscopic examination), physiological (growth in the presence of Salt (NaCl), growth at different pH values and growth at different temperatures) and biochemical methods (the LOPAT and Galeries Api 20 NE test to identify species of the Pseudomonas group and conventional biochemical tests to identify the subspecies P. syringae pv. Savastanoi).This allowed to identify 110 isolates of Pseudomonas (60 isolates of P. aeruginosa, 35 isolates of P. fluorescens and 15 isolates of P. syringae pv Savastanoi the causal agent of olive node disease) which are now part of the collection of Pseudomonas bacteria of the laboratory of the Biotechnology Department (USTO-MB). The selection of technological performance isolates useful for our agriculture could solve phytopathological problems and finally constitute a collection of the bacteria preserved.
