Education, Job Insecurity and the Within Country Migration of Couples

Abstract We consider the migration movements of power couples (couples where both members have at least a college degree), half-power and no-power couples within Australia. We explicitly allow for potential association of these movements with local labour market features including perceived job insecurity. The results support an urbanisation hypothesis; partnered college graduates like to live in major cities regardless of their gender or the qualifications of their partner. JEL Classification: J3, J

Gibberellins modulate auxin responses during tomato (Solanum lycopersicum L.) fruit development

In tomato, auxin and gibberellins (GAs) interact with each other to drive fruit growth and development. While the role of auxin in directing GA biosynthesis and signal is already known, very little information has been obtained about GA-mediated control of auxin signalling and response. Interestingly, we show that gibberellic acid (GA 3 ) is able to modify the expression of several auxin signalling genes in the partial auxin-insensitive diageotropica (dgt) mutant, suggesting that GAs may override the control of DGT on auxin signal. Procera (pro) mutation, which confers a constitutively active GA signal, enhances the effects of exogenous auxin, indicating that PRO may act as a negative effector of auxin responses in fruits. Indeed, transcript modulation of some auxin/indole acetic acid and auxin response factor genes in auxin-treated dgt/pro fruits suggests that PRO controls their expression possibly bypassing DGT. It was also shown that GA biosynthesis, in response to auxin treatment, is largely controlled by DGT. It is therefore conceivable that the DGT-mediated increase of active GAs in auxin-treated or pollinated fruits would promote PRO degradation, which in turn activates part of the auxin signalling cascade.Fil: Mignolli, Francesco.

Job Insecurity within the Household : Are Australian Householders Caring when it Comes to Risk Sharing?

We investigate perceived job security risk and the distribution of non-labour income between spouses in a household context. In the process, the restrictions implied by Beckerian-caring preferences in the Chiappori (2002) Collective model are considered, and estimates of the sharing rule are derived. The findings support the idea of household formation as a tool that caring partners use to share risk. Our results provide further insight as to how unemployment risk may affect interaction between Australian spouses

Embolization of iliac metastasis during lenvatinib treatment in patient with advanced Hürthle cell thyroid carcinoma

Lenvatinib is a tyrosine kinase inhibitor (TKI) with antiproliferative and antiangiogenic effects indicated for the treatment of progressive, locally advanced or metastatic progressive thyroid carcinoma, refractory to radioactive iodine therapy. Antiangiogenic therapies induce ischemic necrosis of tumor tissue, with increased risk of hemorrhagic complications. The management of hemorrhagic risk is based on precautionary measures and for any surgical procedure, it is advised to interrupt the treatment in order to avoid complications. 'Flare-up' of tumor activity may follow TKI interruption. However, it is not known if continuing TKIs during minimally invasive interventions is safe. We report here the first case in which an embolization of metastasis is performed without interrupting lenvatinib treatment. The procedure was successful and free of complications

Ethylene and Chitosan Affected the Seed Yield Components of Onion Depending More on the Dose than Timing of Application

(1) Background: the production of onion seeds is limited by the competition between seeds and the vegetative organs and by scape lodging. However, information on the effects of plant growth regulation on onion seed production is scarce. Aim of the present study was to evaluate the seed yield components and germination ability of onion seeds as affected by the timing and dose of an ethylene application, a plant growth regulator able to modulate shoot–flower competition; and chitosan, an elicitor of plant defense mechanisms able to increase its tolerance to various stresses. (2) Methods: Onion was treated with ethylene at the recommended dose (100% RD) of a commercial product, at 150% RD in two contrasting phenological phases or untreated (control), or ‘with’ or ‘without’ chitosan, and the seed yield components and germination trend were measured. (3) Results: 100% RD at an early phase of growth did not influence the seed yield and increased the thousand seed weight (TSW) by 3.2%. The application of 150% RD decreased the seed yield by 33.5%, and this occurred irrespective of the timing of application. Such decreases were due to a reduction in the number of seeds per flower. The application of chitosan did not affect the crop at 100% RD and increased the seed yield and slightly increased, but not significantly, the TSW under 150% RD. Germination of the fresh seed was 92%, and 17 months of aging reduced it by 14%, with no effects of the treatments on the germination pattern. (4) Conclusions: the ethylene application mostly affected TSW but not the yield, whereas high doses of ethylene reduced yields irrespective of the timing of application. Such a result may have been due to a delay in the flowering onset that occurred in a relatively dry month. Chitosan sustained its yield when the yield potential was reduced by 150% RD, and such a result was likely due to physical protection from the transpiration since the synthetic fungicides applied did not likely allow the pathogens to infections. These results have implications for establishing the timing and dose of application of plant growth regulators and elicitors in seed onions to sustain the seed quality

Forest Road Planning, Construction and Maintenance to Improve Forest Fire Fighting: a Review

Forest roads play a key-role in fire fighting activities. In fact, all ground-based activities are strictly related to the presence of forest roads as access to fire edge. In spite of this important role, forest roads are often planned and built without considering their use in fire fighting, and this also occurs in literature, where few studies are dedicated to the importance of forest roads in fire fighting. A well-developed and well-maintained forest road network is the answer to different needs in fire management. The objective of this review is to clarify basic principles for obtaining efficient road network also for fire fighting, collecting, defining and resuming the main roles, the most important aspects and the reported experiences to be taken into account in forest road network planning and maintenance in fire-prone areas. The most important themes treated are related to: i) the analysis of the functions of forest roads in fire prevention and suppression; ii) the importance of forest road planning and building also considering their importance for protecting forests against fires: iii) the construction and maintenance characteristics to be considered for building and maintaining an efficient forest road network against fires; iv) the importance of fire prevention and the related role of forest roads. Special attention has been dedicated to maintenance activities, because a not well-maintained forest road is a not efficient forest road, and it represents a useless economic and environmental cost

Structural changes of in vitro matured buffalo and bovine oocytes following cryopreservation.

The aim of this work was to evaluate chromatin and spindle organization of buffalo and bovine in vitro matured oocytes after vitrification/warming by Cryotop and after their exposure to cryoprotectants (CP). In vitro matured oocytes were vitrified/warmed and exposed to the vitrification/warming solutions containing ethylene glycol (EG), dimethyl sulfoxide (DMSO) and sucrose as CP. Two hours after warming, oocytes were fixed and immunostained for microtubules and nuclei and examined by fluorescence microscopy. Data were analyzed by Chi Square test. A higher percentage of Telophase II stage oocytes was found in the toxicity (26 and 34% in bovine and buffalo) and the vitrification groups (13 and 7% in bovine and buffalo) compared to the control, indicating occurrence of activation. An increased percentage of oocytes with abnormal spindle and chromosome organization was found in oocytes exposed to CP (24 and 13% in bovine; 32 and 30% in buffalo respectively) and in those vitrified (26 and 31% in bovine; 26 and 29% in buffalo respectively) compared to the control (0 in bovine and 2.5 % in buffalo)
