Abstract A. donax has played an important role in the culture of the western world through its influence on the development of music, which can be traced back 5000 years. A. donax cane was the source of the original Pan pipe or syrix and to this day the A. donax culms remain an unrivalled source of reeds for woodwind instruments. A. donax has been purposefully introduced by man and cultivated into many of the subtropical and warm temperate areas of the world for a number of uses. It is planted as an ornamental and cultivated for a variety of uses including erosion control along ditches and drainage canals. It is available via the nursery trade and spreads as a garden escapee and through the disposal of garden waste.

Arundo Donax L

Arundo donax L. (giant reed) is a perennial rhizomatous grass and has been identified as an important non-food biomass crop with capacity for cultivation in marginal and degraded lands where water scarcity conditions frequently occur due to climate change. This review analyzes the effect of water stress on photosynthetic capacity and biomass production in multiple giant reed ecotypes grown in different regions around the world. Furthermore, this review will attempt to explain the reason for the high photosynthetic capacity of giant reed even under changing environmental conditions as well as indicate other morphological reasons that could contribute to maintaining this high photosynthetic rate. Finally, future research in favor of selecting ecotypes with drought tolerance is proposed.

The Voice

There are two most inevitable issues on national literature, in this case Indonesian literature. First is the translation and the second is the standard of world literature. Can one speak for the other as a representative? Why is this representation matter? Does translation embody the voice of the represented? Without translation Indonesian literature cannot gain its recognition in world literature, yet, translation conveys the voice of other. In the case of production, publication, or distribution of Indonesian Literature to the world, translation works can be very beneficial. The position of Indonesian literature is as a part of world literature. The concept that the Western world should be the one who represent the subaltern can be overcome as long as the subaltern performs as the active speaker. If the subaltern remains silent then it means it allows the “representation” by the Western.

BACKGROUND Western world health care systems have been trying to improve their efficiency and effectiveness in order to respond properly to the aging of the population and the epidemic of noncommunicable diseases. Errors in drugs administration is an actual important issue due to different causes. OBJECTIVE Aim of this study is to measure interest in online seeking medical errors information online related to interest in risk management and shift work. METHODS We investigated Google Trends® for popular search relating to medical errors, risk management and shift work. Relative search volumes (RSVs) were evaluated for the period November 2008-November 2018 all around the world. A comparison between RSV curves related to medical errors, risk management and shift work was carried out. Then we compared world to Italian search. RESULTS RSVs were persistently higher for risk management than for medication errors during the study period (mean RSVs 74 vs. 51%) and RSVs were stably higher for medical errors than shift work during the study period (mean RSVs 51 vs 23%). In Italy, RSVs were much lower than the rest of the world, and RSVs for medication errors during the study period were negligible. Mean RSVs for risk management and shift work were 3 and 25%, respectively. RSVs related to medication errors and clinical risk management were correlated (r=0.520, p<0.0001). CONCLUSIONS Google search query volumes related to medication errors, risk management and shift work are different. RSVs for risk management are higher, are correlated with medication errors, and the relationship with shift work appears to be even worse, by analyzing the entire world. In Italy such a relationship completely disappears, suggesting that it needs to be emphasized by health care authorities.

Riparian Systems

Arundo donax (giant reed) is invasive in Mediterranean, sub-, and tropical riparian systems worldwide. The armored scale Rhizaspidiotus donacis is approved for biocontrol in North America, but an adventive population was recently discovered in southern California. We documented this population’s distribution, phylogeny, phenology, potential host spillover to Phragmites spp., and potential for parasitism by a common biocontrol parasitoid of citrus scale. The adventive scale was found within a single watershed and is genetically closest to Iberian scale genotypes. Rhizaspidiotus donacis developed on Phragmites haplotypes but at much lower densities than Arundo. The adventive population is univoltine, producing crawlers from March-June. Aphytis melinus parasitoids exhibited sustained interest in R. donacis during choice and no-choice trials and oviposition resulted in a small second generation. Rhizaspidiotus donacis appears limited in distribution by its univoltinism and sessile adult females. This presents challenges for broad biocontrol implementation but allows for targeted application. The genetic differentiation between imported biocontrol samples and adventive populations presents an opportunity for exploring benefits of hybrids and/or alternative genotypes where establishment has been difficult. While unlikely to occur in situ, spillover to vulnerable endemic Phragmites or deleterious parasitoid effects on scale biocontrol agents warrants consideration when planning use of R. donacis.

The Impact

Estimating the main hydrodynamic features of real vegetated water bodies is crucial to assure a balance between their hydraulic conveyance and environmental quality. Riparian vegetation stands have a high impact on vegetated channels. The present work has the aim to integrate riparian vegetation’s reflectance indices and hydrodynamics of real vegetated water flows to assess the impact of riparian vegetation morphometry on bulk drag coefficients distribution along an abandoned vegetated drainage channel fully covered by 9–10 m high Arundo donax (commonly known as giant reed) stands, starting from flow average velocities measurements at 30 cross-sections identified along the channel. A map of riparian vegetation cover was obtained through digital processing of Unnamed Aerial Vehicle (UAV)-acquired multispectral images, which represent a fast way to observe riparian plants’ traits in hardly accessible areas such as vegetated water bodies in natural conditions. In this study, the portion of riparian plants effectively interacting with flow was expressed in terms of ground-based Leaf Area Index measurements (LAI), which easily related to UAV-based Normalized Difference Vegetation Index (NDVI). The comparative analysis between Arundo donax stands NDVI and LAI map enabled the analysis of the impact of UAV-acquired multispectral imagery on bulk drag predictions along the vegetated drainage channel.
