The Consistency of Rural Development Policies with the Position of the European Union on NTCS

The set of policy tools that the EU puts under the heading of Rural Development is extremely heterogeneous, such heterogeneity translates into a different degree of coupling support with agriculture production and also brings out the need to discuss the actual consistency of such tools with the UE position on NTCs at WTO. Examined in the present work are the Rural Development Plans (RDPs) and the Regional Operative Plans (ROPs) recently approved by the European Commission for the Italian Regions. The analysis is of a purely qualitative type and is based on currently available information, that is, the measures and the relative project typologies approved within the Plans. Taking into account the EU position on NTCs and their relation with multifunctionality we look at the tools applied for Rural Development in Italy with respect to their degree of de-coupling, production of externalities/non marketable goods and consistency with the EU position on NTCs. Financial allotment by measure typology is also examined. We found out that the present set of actions that fall under rural development is still dominated by a sector−based intervention, even in the case of measures aimed at safeguarding the environment, the least contestable ones. Paradoxically, the measures aimed at the promotion of Rural Development and at training, that better respond to the NTC objectives, are those for which the least resources are located.Non trade concerns, multifunctionality, rural development policies., Community/Rural/Urban Development,

Schur Subalgebras and an Application to the Symmetric Group

AbstractLet K be an infinite field of prime characteristic p and let d≤r be positive integers of the same parity satisfying a certain congruence condition. We prove that the Schur algebra S(2,d) is isomorphic to a subalgebra of the form eS(2,r)e, where e is a certain idempotent of S(2,r). Translating this result via Ringel duality to the symmetric groups Σd and Σr, we obtain lattice isomorphisms between Specht modules, between Young modules, and between permutation modules. Here modules labelled by the partitions (r−k,k) correspond to modules labelled by (d−k,k). This provides a representation theoretical interpretation for part of the fractal structures observed for the decomposition numbers of the symmetric groups corresponding to two-part partitions

Coyotes: Friends or Foe of Northern Bobwhite in Southern Texas

Food habits of 407 coyotes (Canis latrans), intermittently collected in southern Texas from March 1994 to January 1997, were determined from coyote stomachs. Mammalian prey was the most prevalent diet item as calculated by frequency of occurrence and aggregate percent methods, followed by insects, vegetation, birds, and reptiles. The remains of northern bobwhite (Colinus virginianus) or their eggs were found in only 12 coyote stomachs, which constituted 1% of the coyote diet as calculated by the aggregate percent method. Northern bobwhite appear to be an incidental prey item for coyotes in southern Texas. Therefore, coyote removal programs designed to lessen quail depredation appear unwarranted

Use of Passive Integrated Transponders in Hatchling Texas Horned Lizards

The Texas horned lizard (Phrynosoma cornutum) is a Texas state-threatened species and acquisition of data related to the species\u27 ecology is essential. To accomplish this task individual animals need to be marked. Many marking techniques are available for lizards, however the majority of techniques have been tested on adults only. Studies involving hatchling and juvenile horned lizards are scarce due to problems associated with marking and relocating individuals in these age classes. I demonstrated that injection of passive integrated transponders (PIT\u27s) can safely be used as a marking method in young Texas horned lizards. Thirty-two captive bred hatchling lizards were used. Hatchlings were allowed to grow to 20 mm snout-vent length (SVL) before PIT\u27s were inserted into 16 hatchlings while the other 16 hatchlings were used as control animals. Hatchlings were measured and weighed weekly for 14 weeks and blood samples obtained weekly for 3 weeks to assess if PIT\u27s affected lizard growth and health. No differences were noted in treatment effects for SVL (F1450 = 0.85, P = 0.37), weight (F1,450 = 1.60, P = 0.22), or white blood cell and differential counts (F1,30 \u3c 1.47, P \u3e 0.23). However, an interaction between treatment and week occurred (F I4.450 = 1.79, P = 0.04) for SVL. Texas horned lizard hatchlings that were PIT-tagged were larger in SVL during weeks 3, 7 to 10, and 12 than control lizards. No ditferences in SVL were noted between treatment groups during the remaining weeks. A duration effect was noted for both SVL (F 14,450 = 7654.0, P = 0.0001) and mass (F14,450 = 1595.1, P = 0.000 I). Snout-vent length for both PIT-tagged and control lizards increased weekly until week 12 when growth rate began to slow down. Mass gain for both groups of lizards was similar, with weekly spurts occurring except between weeks 0 and 1,7 and 8, 12 and 13, and 13 and 14. Passive integrated transponders did not interfere with the growth or health of young Texas horned lizards; therefore, they can be safely used as a marking tool

Sensible introduction of MR-guided radiotherapy: A warm plea for the RCT

Magnetic resonance guided radiotherapy (MRgRT) is the newest face of technology within a field long-characterized by continual technologic advance. MRgRT may offer improvement in the therapeutic index of radiation by offering novel planning types, like online adaptation, and improved image guidance, but there is a paucity of randomized data or ongoing randomized controlled trials (RCTs) to demonstrate clinical gains. Strong clinical evidence is needed to confirm the theoretical advantages of MRgRT and for the rapid dissemination of (and reimbursement for) appropriate use. Although some future evidence for MRgRT may come from large registries and non-randomized studies, RCTs should make up the core of this future data, and should be undertaken with thoughtful preconception, endpoints that incorporate patient-reported outcomes, and warm collaboration across existing MRgRT platforms. The advance and future success of MRgRT hinges on collaborative pursuit of the RCT
