Targeting fertility and female participation through the income tax

We evaluate the effect of a 2003 reform in the Spanish income tax on fertility and the employment of mothers with small children. The reform introduced a tax credit for working mothers with children under the age of three, while also increasing child deductions for all households with children. Theoretically, given the interplay of these two components, the expected effect of the reform is ambiguous on both outcomes. We find that the combined reforms significantly increased both fertility (by almost five percent) and the employment rate of mothers with children under three (by two percent). These effects were more pronounced among less-educated women. In addition, to disentangle the impact of the two reform components, we use an earlier reform that increased child deductions in 1999. We find that the child deductions affect mothers employment negatively, which implies that the 2003 tax credit would have increased employment even more (up to five percent) in the absence of the change in child deductions.

Traitement des fractures de l'enfant par enclouage centro-médullaire élastique stable (ECMES) [Treatment of pediatric fractures by intramedullary stable elastic pinning]

During the past decade several new techniques for the treatment of children's fractures respecting the specificity of the growing bone have been described. The goal of all these techniques was to mechanically stabilise the fracture however to preserve a certain instability of the fracture gap itself inducing early callus formation and subsequent consolidation. The dynamic external fixation as well as the elastic stable intramedullary pinning have become accepted means in the treatment of long bone fractures in the paediatric age group. We report our experience of the last seven years with the intramedullary pinning of 105 fractures. Eighty-four were fractures of the femur, 9 of the humerus, 8 of the forearm, and a further 4 of the tibial shaft. The intramedullary elastic pinning represents a simple technique which supports or even enhances the natural process of fracture healing of the growing bone. The method is not very invasive, is cost effective, and allows short hospitalisation. Early physical activity is guaranteed due to early consolidation of the fracture. Complications are rare and the final orthopedic and cosmetic outcome is excellent.

Myospila bekilyana (Séguy) (Diptera, Muscidae, Mydaeinae): redescription of male and female and description of terminalia

Myospila bekilyana Séguy (Diptera, Muscidae, Mydaeainae) is an endemic species from Madagascar. Since the original description, the species has been referred in literature only in catalogues. A material recently collected by the Madagascar Arthropod Biodiversity project, mostly deposited at the California Academy of Sciences collection enabled the exam of a large series of this species. Male and female are herein redescribed and the terminalia of both sexes are described and illustrated for the first time. The paper also records Myospila as a new host for Stylogaster Macquart (Diptera, Conopidae).

Prevalence of restless legs syndrome in female blood donors 1 week after blood donation.

BACKGROUND AND OBJECTIVE: Restless legs syndrome (RLS) is a frequent condition with a prevalence of 5-15% in the general population. Clinical and genetic observations have shown that iron deficiency, highly prevalent among blood donors, can be related to RLS. The objective of this study was to assess the prevalence of RLS in female blood donors 1 week after blood donation. METHODS: One week after blood donation, 291 female blood donors, aged <50 years, self-responded to all four RLS questions defined by the 1995 International RLS study group. Blood donation rate, fatigue, aerobic capacity, menstruation, mood disorder and quality of life were also assessed along with haemoglobin and ferritin blood concentrations. RESULTS: Prevalence of RLS in female blood donors 1 week after blood donation was 6·9% (CI 95% 4·2-10·4%). Female blood donors with RLS had a higher prevalence of hyper-menorrhaea (P = 0·033) and were significantly more tired (P = 0·001). We observed no associations between RLS and number of previous donations (P = 0·409), aerobic capacity (P = 0·476), mood disorder (P = 0·169), quality of life (P = 0·356), haemoglobin (P = 0·087), and serum ferritin level (P = 0·446). CONCLUSION: Restless legs syndrome prevalence in female blood donors is not as important as described in some other studies, which could reassure blood donors. The prevalence of hypermenorrhaea and fatigue is higher in RLS blood donors. Therefore, screening for fatigue and hypermenorrhaea could be considered as these symptoms are associated with RLS in female blood donors.

The so-called 'external partners' in the groups of corporations: A model of presentation in the consolidated statements

This paper studies, on the one hand, theories set out around theconsideration of the external partners in the consolidated informationand on the other hand, financial models that discuss the convenience ofthe separation or not of the different elements that form part of theliabilities of the balance sheet of the companies. A Model is proposed,the External Partners Model, which financially argues a certain presentationand processing of such and that, in our opinion, facilitates the analysisof the consolidated financial statements. This model is based on twohypotheses: (1) the economic and financial variables are not independentand (2) the value of the company depends, among other factors, of thetype of sources that constitute their capital. These two hypotheses willimply that a separation should be included in the consolidated balance sheet between equity and liabilities as they are different sources ofcapital and then its separation will give relevant information to itsusers.

Female labour supply in Spain: The importance of behavioural assumptions and unobserved heterogeneity specification

We estimate four models of female labour supply using a Spanish sampleof married women from 1994, taking into account the complete form of theindividual s budget set. The models differ in the hypotheses relating tothe presence of optimisation errors and/or the way non-workers contributeto the likelihood function. According to the results, the effects of wagesand non-labour income on the labour supply of Spanish married women dependon the specification used. The model which has both preference andoptimisation errors and allows for both voluntarily and involuntarilyunemployed females desiring to participate seems to better fit the evidencefor Spanish married women.

More than one inseminated female in colonies of the independent-founding wasp Mischocyttarus cassununga von Ihering (Hymenoptera, Vespidae)

In the primitively eusocial wasps, especially Polistini and Mischocyttarini tribes, the physiological condition of each individual is strongly associated with its dominance status in the colonial hierarchy. As a rule, in independent-founding wasps, female wasps are all morphologically alike, and their role is apparently quite flexible even as adults. However, some studies have shown that differences in body size can exist between reproductive and non-reproductive females. Thus, the present study aimed at detecting differences between reproductive (inseminated) and non-reproductive (uninseminated) individuals based on morphological and physiological parameters. We tape-recorded the daily behavioural repertory of six colonies of Mischocyttarus cassununga for determining the hierarchical dominance in the field, and then collected these colonies (in different cycle stages) for measuring 13 set characters, and assessing the physiological condition of each individual by inspecting their fat bodies and ovaries. Our results revealed that inseminated and uninseminated females are not significantly different in relation to body size, in spite of first group shows higher average than second in almost all measured parts. The physiological evaluation of each individual demonstrated more than one inseminated female per colony during all stages of the colony cycle, suggesting a strategic condition of this species against difficulties (predation and parasitism of the colony) in nature.

Exposure of a single host (Chrysomya megacephala) (Calliphoridae) to different quantities of female parasitoids (Nasonia vitripennis) (Pteromalidae)

The aim of this study was to verify the duration of the development period, number of parasitoids produced per pupa, parasitism rate and sex ratio of Nasonia vitripennis (Hymenoptera, Pteromalidae), when they were exposed to a single host: Chrysomya megacephala (Diptera, Calliphoridae). One pupa was exposed in glass tubes to different numbers of female parasitoids (1, 3, 5, 7, 9 and 11) during 48 h. Twenty replications/treatment were used, under controlled conditions (T= 27 °C day/ 25 °C night, 60 ± 10% RH). Statistical analysis of the data was made using the ANOVA test and the "a posteriori" comparisons were made using the Tukey-HSD test (both tests with a significance level of 5%). The duration of the development period was longer in treatments where a higher density of females per host was used. When five females per host were used, the mean number of parasitoids that emerged per pupa was higher. The data showed a tendency to a decrease in the amount of parasitoids emerged per host, especially of female, when used high quantities of female per host. Higher parasitism rates were observed in the 3:1 and 5:1 treatments and an increase in the percentage of unviable pupae was observed, probably due to an increase of female densities in the treatments, possibly a consequence of superparasitism.

Functional response of Telenomus remus Nixon(Hymenoptera, Scelionidae) to Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) eggs: effect of female age

Functional response of Telenomus remus Nixon (Hymenoptera, Scelionidae) to Spodoptera frugiperda (J. E. Smith) (Lepidoptera, Noctuidae) eggs: effect of female age. Functional response of 24-h and 48-h-old Telenomus remus adults was studied on Spodoptera frugiperda eggs. The study was carried out in climatic chamber regulated at 25 ± 1°C, 70 ± 10% RH and 12:12h (L: D). Females of T. remus were honey fed and individualized in glass vials along with 25, 50, 75, 100, 150, 200, 250 or 300 eggs of S. frugiperda for 24 h. Complete randomized design with ten replications was adopted. The parameters evaluated to construct the functional response curve were daily average parasitism, searching rate and oviposition time. It was observed that the higher the egg density, the higher the parasitism for 24-h and 48-h-old females although there was a tendency of parasitism stabilization at 150-egg density. The results showed a type II functional response curve for both 24-h and 48-h-old female.

Whole brain radiotherapy with a conformational external beam radiation boost for lung cancer patients with 1-3 brain metastasis: a multi institutional study.

BACKGROUND: To determine the outcome of patients with brain metastasis (BM) from lung cancer treated with an external beam radiotherapy boost (RTB) after whole brain radiotherapy (WBRT). METHODS: A total of 53 BM patients with lung cancer were treated sequentially with WBRT and RTB between 1996 and 2008 according to our institutional protocol. Mean age was 58.8 years. The median KPS was 90. Median recursive partitioning analysis (RPA) and graded prognostic assessment (GPA) grouping were 2 and 2.5, respectively. Surgery was performed on 38 (71%) patients. The median number of BM was 1 (range, 1-3). Median WBRT and RTB combined dose was 39 Gy (range, 37.5-54). Median follow-up was 12.0 months. RESULTS: During the period of follow-up, 37 (70%) patients died. The median overall survival (OS) was 14.5 months. Only 13 patients failed in the brain. The majority of patients (n = 29) failed distantly. The 1-year OS, -local control, extracranial failure rates were 61.2%, 75.2% and 60.8%, respectively. On univariate analysis, improved OS was found to be significantly associated with total dose (< or = 39 Gy vs. > 39 Gy; p < 0.01), age < 65 (p < 0.01), absence of extracranial metastasis (p < 0.01), GPA > or = 2.5 (p = 0.01), KPS > or = 90 (p = 0.01), and RPA < 2 (p = 0.04). On multivariate analysis, total dose (p < 0.01) and the absence of extracranial metastasis (p = 0.03) retained statistical significance. CONCLUSIONS: The majority of lung cancer patients treated with WBRT and RTB progressed extracranially. There might be a subgroup of younger patients with good performance status and no extracranial disease who may benefit from dose escalation after WBRT to the metastatic site.

Shoulder arthroplasty for patients with juvenile idiopathic arthritis.

Between 1986 and 1997, 13 shoulders in adult patients who had severe polyarticular juvenile idiopathic arthritis were treated with primary arthroplasty. Eleven shoulders were evaluated retrospectively by an independent observer with a mean follow-up of 9 years. Patient evaluation included pain Visual Analogue Scale, range of motion, Disabilities of the Arm, Shoulder and Hand score, and Short-Form 36. Patients' pain decreased significantly after surgery (mean 6.7). Forward elevation improved on average by 41.1 degrees and external rotation by 39.1 degrees , without evidence of shoulder instability. Final Short-Form 36 scores and Disabilities of the Arm, Shoulder and Hand results (mean, 44.7) were poor, but all patients rated themselves satisfied with the procedure. Shoulder arthroplasty provided pain relief for end-stage shoulder involvement in adult juvenile idiopathic arthritis. Improvement in external rotation in this severely affected group appears to have a beneficial effect on functional outcome.

Comparative morphology of the mandibles of female polistine social wasps (Hymenoptera, Vespidae, Polistinae)

Comparative morphology of the mandibles of female polistine social wasps (Hymenoptera, Vespidae, Polistinae). Diversity of mandibular forms in female polistines is explored and compared among 116 species of all polistine genera. Inferences about function are made and discussed based on observed form differences. Mandible length and width measurements are analyzed for a subset of polistine species plus two vespines and two eumenines. A variable expressing the ratio between these variables is also considered in morphometric analyses. The following mechanical interactions among mandible structural elements are highlighted: opposition and crossing of mandibles' apical teeth at the middle of the closing trajectory; shearing action of the apical teeth against mesial denticles of the opposite mandible; shearing action of the mandible anterior margin against the ventral margin of the clypeus. In the genera Agelaia and Angiopolybia, exceptionally developed mesial mandibular structures may be related to necrophagy. In some epiponine genera, poorly developed mesial denticles and strong torsion of mandibles may be partially related to use of short wood fibers in nest construction as advanced by Sarmiento (2004). The considerable morphological variation found across the subfamily Polistinae is certain to be important in taxonomic and phylogenetic studies at the genus and species levels.
