AbstractRising concentrations of carbon dioxide (CO2) is likely to have important effects on growth and development of plants and on their relationship with symbiotic microbes. A rise in CO2 could increase demand by plant hosts for nutrient resources, which may increase host investments in beneficial symbionts. In the legume-rhizobia mutualism, while elevated CO2 is often associated with increased nodule growth and investment in N2-fixing rhizobia, it is yet unclear if this response depends on the mutualistic quality of the rhizobia. To test if host carbon allocation towards more-beneficial nodules are similar to less-beneficial (but still effective) nodules when plant N demand changes, we manipulated plant C and N status with elevated CO2 and additional nitrate. We used two isogenic Rhizobium etli strains that differ in their ability to synthesize an energy reserve compound, poly-beta-hydroxybutyrate (PHB), as well as their efficiencies for nitrogen fixation and nodulation rates, resulting in two Phaseolus vulgaris host groups with either large number of small nodules or small number of large nodules. The addition of nitrate negatively affected carbon allocation towards nodules, and elevated CO2 reversed this effect, as expected. However, this alleviation of nodule inhibition was greater on plants that started with greater numbers of smaller nodules. If smaller nodules indicate less-efficient or low-fixing rhizobia, this study suggests that increased demand for nitrogen in the face of elevated CO2 has the potential to disproportionately favor less-beneficial strains and increase variation of nitrogen fixation quality among rhizobia.

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.

The use of videoconferencing in psychotherapy remains largely unexplored. Videoconferencing compromises the range and quality of interactional information and thus might be expected to affect the working alliance (WA) between client and therapist, and consequently the process and outcome of therapy. A single case study exploring the effect of videoconferencing on the development of the WA in the psychological treatment of a female–male transsexual is described. The self-rated Working Alliance Inventory (WAI) was used to measure client and therapist perceptions of the WA after each session over 10 sessions of eclectic therapy conducted over a videolink. The serial WAI measurements charting the development of the WA in 4 cases of 10-session, face-to-face therapy by Horvath and Marx1 were used as a quasi-control. Therapist and client impressions of teletherapy are described. WAI scores were essentially similar to the face-to-face control group except for lower client-rated bond subscale scores. It is suggested that client personality factors accounted for this difference and that videoconferencing did not impair the development of an adequate working alliance or successful therapeutic outcome.

Classical Style

Although Europa 51 (1952) was the most commercially successful of the films Roberto Rossellini made with the Hollywood star, Ingrid Bergman, the reception by the Italian press was largely negative. Many critics focussed on what they saw to be the ‘unreal’ or abstract quality of the films portrayal of the postwar urban milieu and on the Bergman character‘s isolation from the social world. This article looks at how certain structures of seeing that are associated in the classical style with the woman as star or spectacle - e.g., the repetitious return to her fixed image, the resistance to pulling back from the figure of the woman in order to situate her within a determinate location and set of relationships between characters and objects - are no longer restricted to her image but in fact bleed into or “contaminate” the depiction of the world she inhabits. In other words, whereas the compulsive return to the fixed image of the woman tends to be contained or neutralised by the narrative economy and editing patterns (ordered by sexual difference) of the classical style, in Rossellini‘s work this ‘insistent’ even aberrant framing in relation to the woman becomes a part of the (female) characters and the cameras vision of the ‘pathology’ of the urban landscape in the aftermath of the war.

The mandible is the most important bone structure of the facial makeup. Its morphology differs with respect to genetic factors, sexual dimorphism, and age. Among its particular characteristics is the ability to adapt with its counterpart, the base of the skull, conferring a dynamic quality of this bone, by the mechanism of constant remodeling. In order to understand the involvement of the mandible in the evaluation of the lower third of the face, a fractional analysis of its parts is necessary considering morphological parameters of the mandibular angle. The purpose of this study is to demonstrate the importance of the mandible as an instrument in the analysis of the lower third of the face, allowing the accomplishment of aesthetic treatment, respecting the individual characteristics.

N Demand

Abstract In legumes interacting with rhizobia the formation of symbiotic organs involved in the acquisition of atmospheric nitrogen is depending of the plant nitrogen (N) demand. We used Medicago truncatula plants cultivated in split-root systems to discriminate between responses to local and systemic N signalings. We evidenced a strong control of nodule formation by systemic N-signaling but obtained no clear evidence of a local control by mineral nitrogen. Systemic signaling of the plant N demand controls numerous transcripts involved in the root transcriptome reprogramming associated to early rhizobia interaction and nodule formation. SUNN has an important role in this control but major systemic N signaling responses remained active in the sunn mutant. Genes involved in the activation of nitrogen fixation are regulated by systemic N signaling in the mutant, explaining why the hypernodulation phenotype is not associated to a higher nitrogen fixation of the whole plant. The control of the transcriptome reprogramming of nodule formation by systemic N signaling requires other pathway(s) that parallel the SUNN/CLE pathway.

Why does professional misconduct persist in the face of media scrutiny? In this study, we explain how professional norms can be at odds with societal norms and how the behaviours they trigger can be perceived as misconduct. Most audiences tend to disapprove of wrongdoings, but specific stakeholders may interpret this disapproval as an indication of the focal organization’s level of adherence to professional norms. Building on mixed methods, we explore the case of the investment banking industry during the financial crisis and suggest that corporate customers were favourably biased by the reporting of banks’ misconduct in the print media as they linked it to the banks’ quality of service. We capture the extent to which banks are associated with misconduct, signalling their adherence to negatively perceived professional norms. We then look at how such signalling affects the likelihood for banks to be invited into initial public offerings syndicates. Our findings show that the more banks are disapproved of for their wrongdoings, the more likely they are to be selected to join a syndicate. This study suggests that the coverage of misconduct can actually act as a positive signal providing banks with incentives to engage in what is broadly perceived as professional misconduct.

Background. Vascularized osteoseptocutaneous radial flap is commonly used in the reconstruction of composite bony and soft tissue defects of the lower third of the face due to the outstanding quality of its cutaneous component. The aim was to evaluate the primary and overall success in the reconstruction of mandibular defects, following war injuries, with vascularized osteoseptocutaneous radial flap. Methods. At the Department of Maxillofacial Surgery of the Military Medical Academy Belgrade, there were eight patients with this kind of defect following war injury, and the mandible was reconstructed with a vascularized osteoseptocutaneous radial flap. Bony compartment of the graft was harvested as up to 11 cm long segment of radial circumference. Results. The localization and structure of the defect, features of a harvested compound graft, the procedure of the reestablishment of the mandibular continuity was presented as well as immediate and late complications during the consolidation period, and the primary successful reconstruction in 87.5% of the patients. Conclusion. The primary and overall success in the mandibular defects reconstruction with a vascularized osteoseptocutaneous radial flap was equal or even better than those presented in the literature on the reconstruction of the similar defects after tumor resections.

Satisfaction with quality of life and self-attitude in patients operated by «traditional» (conventional surgical methods) and endoscopically assisted methods are considered in the article. Differences in the quality of life in patients, self-attitude to ones appearance are described. 65 patients were surgically operated and examined. Control group – patients operated by «traditional» techniques (35 patients), the average age of patients was 38 ± 11,1 years. The comparison group – patients operated using endoscopically assisted methods (30 patients), the average age of patients was 44 ± 17,7 years. Psychodiagnostic methods: 1. N. E. Vodopyanova`s scale of life quality; 2. The Short Form-36; 3. S.R. Panteleev`s Assessment of self-relationship. Complaints of paresthesia and pain experienced by patients who underwent a “traditional” operation were revealed as a result of the examination. Operated on with an endoscopically assisted method patients did not present any complaints. Differences between the assessment of the life quality and self-relationship in examined groups were found. Operated on with an endoscopically assisted method patients evaluated life quality, satisfaction with their appearance and physical condition higher than patients operated on with a “traditional” method.
