This paper investigates retirees’ optimal purchases of fixed and variable longevity income annuities using their defined contribution (DC) plan assets and given their expected Social Security benefits. As an alternative, we also evaluate using plan assets to boost Social Security benefits through delayed claiming. We determine that including deferred income annuities in DC accounts is welfare enhancing for all sex/education groups examined. We also show that providing access to well-designed variable deferred annuities with some equity exposure further enhances retiree wellbeing, compared to having access only to fixed annuities. Nevertheless, for the least educated, delaying claiming Social Security is preferred, whereas the most educated benefit more from using accumulated DC plan assets to purchase deferred annuities.
The authors examine the effectiveness of labor cost reductions as a means to stimulate economic activity and assesses the differences which may occur with the prevailing exchange rate regime. They develop a medium-scale three-region DSGE model and show that the impact of a cut in the employers’ social security contributions rate does not vary significantly under different exchange rate regimes. They find that both the interest rate and the exchange rate channel matters. Furthermore, the measure appears to be effective even if it comes along with a consumption tax increase to preserve long-term fiscal sustainability.
Finally, they assess whether obtained theoretical results hold up empirically by applying the local projection method. Regression results suggest that changes in employers’ social security contributions rates have statistically significant real effects – a one percentage point reduction leads to an average cumulative rise in output of around 1.3 percent in the medium term. Moreover, the outcome does not differ significantly across the different exchange rate regimes.
In this paper, I argue that this apparent problem is accounted for by the interaction of constraints. For the fixed segment [ɛ] in Cɛ-reduplication, I argue that [ɛ] is the second least marked vowel in Palauan, which appears when the default vowel [ǝ] cannot appear. I show that the Palauan facts are not only consistent with the proposals of Urbanczyk (1999) and Alderete et. al (1999), but they actually provide support of their claims. In the following section, I discuss Urbanczyk's (1999) arguments concerning ROOT faithfulness in reduplication and possible asymmetries between affix reduplicants and root reduplicants. In Section 3, I introduce Palauan reduplication and discuss Finer's (1986) observations on the resulting state verb (RSV) form. I show that the RSV forms support the classification that Cɛ-reduplicants are affixes, and CVCV -reduplicants are roots. In Section 4, I discuss the shape and vowel quality of the two reduplicants. The CVCV-reduplicant has three variants: CǝCǝ, CǝC and CV. I explain this variation, illustrating why [ǝ] appears in the first two variations. Then, I discuss the shape and vowel quality of the Cɛ-reduplicant, arguing that the fixed segment [ɛ] in Cɛ-reduplication is a special case of TETU. I show that root faithfulness constraints are crucial in determining the shape and vowel quality of the reduplicants. Section 5 is the conclusion.
Limbic encephalitis (LE) is an autoimmune syndrome often associated with temporal lobe epilepsy. Recent research suggests that particular structural changes in LE depend on the type of the associated antibody and occur in both mesiotemporal gray matter and white matter regions. However, it remains questionable to what degree conventional diffusion tensor imaging (DTI)-methods reflect alterations in white matter microstructure, since these methods do not account for crossing fibers. To address this methodological shortcoming, we applied fixel-based analysis as a novel technique modeling distinct fiber populations. For our study, 19 patients with LE associated with autoantibodies against glutamic acid decarboxylase 65 (GAD-LE, mean age = 35.9 years, 11 females), 4 patients with LE associated with autoantibodies against leucine-rich glioma-inactivated 1 (LGI1-LE, mean age = 63.3 years, 2 females), 5 patients with LE associated with contactin-associated protein-like 2 (CASPR2, mean age = 57.4, 0 females), 20 age- and gender-matched control patients with hippocampal sclerosis (19 GAD-LE control patients: mean age = 35.1 years, 11 females; 4 LGI1-LE control patients: mean age = 52.6 years, 2 females; 5 CASPR2-LE control patients: mean age = 42.7 years, 0 females; 10 patients are included in more than one group) and 33 age- and gender-matched healthy control subjects (19 GAD-LE healthy controls: mean age = 34.6 years, 11 females; 8 LGI1-LE healthy controls: mean age = 57.0 years, 4 females, 10 CASPR2-LE healthy controls: mean age = 57.2 years, 0 females; 4 subjects are included in more than one group) underwent structural imaging and DTI at 3 T and neuropsychological testing. Patient images were oriented according to lateralization in EEG resulting in an affected and unaffected hemisphere. Fixel-based metrics fiber density (FD), fiber cross-section (FC), and fiber density and cross-section (FDC = FD · FC) were calculated to retrieve information about white matter integrity both on the micro- and the macroscale. As compared to healthy controls, patients with GAD-LE showed significantly (family-wise error-corrected, p < 0.05) lower FDC in the superior longitudinal fascicle bilaterally and in the isthmus of the corpus callosum. In CASPR2-LE, lower FDC in the superior longitudinal fascicle was only present in the affected hemisphere. In LGI1-LE, we did not find any white matter alteration of the superior longitudinal fascicle. In an explorative tract-based correlation analysis within the GAD-LE group, only a correlation between the left/right ratio of FC values of the superior longitudinal fascicle and verbal memory performance (R = 0.64, Holm-Bonferroni corrected p < 0.048) remained significant after correcting for multiple comparisons. Our results underscore the concept of LE as a disease comprising a broad and heterogeneous group of entities and contribute novel aspects to the pathomechanistic understanding of this disease that may strengthen the role of MRI in the diagnosis of LE.
Haplosclerid sponges possessing a unique asymmetric flagelliform type of sigmoid microsclere have been reported from all global oceans. This peculiar spicule, characterized by a circular or elliptical shape, with a longer and sharper curved ending at one side and a shorter and more gradually curved ending at the opposing side, is proposed to be termed ‘flagellosigma’. These sponges invariably also possess smaller normal sigmas while their skeletal structure of oxea megascleres is markedly confused. They are assigned to the large genus Haliclona Grant, 1841 (family Chalinidae) in a new subgenus, Haliclona (Flagellia) subgen. nov. The species belonging to the new subgenus are reviewed and four species new to science are described, Haliclona (Flagellia) indonesiae subgen. et sp. nov., H. (F.) amirantensis subgen. et sp. nov., H. (F.) hiberniae subgen. et sp. nov. and H. (F.) hajdui subgen. et sp. nov. One species, H. (F.) hentscheli nom. nov., is given a new name on account of secondary homonymy caused by its transfer to the genus Haliclona. One species remains unnamed because of paucity of material. Already known species, reassigned to the new subgenus are H. (F.) hamata subgen. et comb. nov., H. (F.) flagellifera subgen. et comb. nov., H. (F.) porosa subgen. et comb. nov., H. (F.) edaphus subgen. et comb. nov. and H. (F.) anataria subgen. et comb. nov. Additional species are likely hiding among many erroneous records of ‘Gellius flagellifer’ from wide ranging parts of the global oceans.
Flame and Song
(2016)
PKK's soul-warming memoir tells of a life enriched by song, literature, food and spirituality at the heart of a loving family. Born into a newly independent Uganda, she grew up in a volatile political landscape but never lacked the inspiration and protection of generations of friends and relatives. Her story travels from her expansive childhood homes in Uganda, to the novelties of living in Addis Ababa, before settling in Cape Town, her current home. But no matter how far her journeys take her, it's clear that home is not only about places but people.

The powerful Oyo has a Shadow Chasers knife and only the cleverest and bravest can withstand the Flame of Truth to win it back from her. With the guidance of Zulaika, a helpful ghost, Nom, Zithembe and Rosy travel through the unknown terrors of the dreamworld to find Oyo and regain the knife.
Flashlight on Drama and Film succinctly describes how to use drama to afford target audiences opportunities to analyse environmental situations, presented through drama, with a view to enabling them to make informed decisions and take responsible actions in similar situations in the real world. This constitutes the guiding principle of Drama for Situation Analysis (DRASA), with Flashlight on Drama and Film as its training guide.in the drama effort. The guide is divided into three parts. Part One looks at the development of the play script from the research stage. Part Two describes the stages involved in interpreting a play, including the skills, techniques and terminology of acting, from a simple definition of drama. Part Three gives a rundown of the stages in rehearsing and presenting a play, either as stage drama or film production.
This synonymic list of the flat bugs (Aradidae) ofthe world enumerates 1,798 species in 211 genera. Names of eight fossil species are given in their original combination in modern genera. The list is introduced by brief discussions of habits, food, ecology and distribution. Many taxonomic innovations are included, as follows: Subfamily Chinamyersiinae is divided into two new tribes, Chinamyersiini and Tretocorini; the subfamily Prosympiestinae is divided into two new tribes, Llaimacorini and Prosympiestini. All currently recognized subgenera are raised to generic rank: Aneurillus, Breviscutaneurus, lralunelus, and Paraneurus from Aneurus; Miraradus and Quilnus from Aradus; Lissaptera and Nesiaptera from Acaraptera; Neoproxius and Nesoproxius from Proxius (see list below for new combinations resulting). Three genus-group names are raised from synonymy: Aneurosoma; Burgeonia and Brachyrhynchus. One genus-group name is reduced to synonymy; Zimera as a junior synonym of Brachyrhynchus. The following new species-genus combinations are made, these mostly resulting from elevation of subgenera to generic status or species transfers. In Aneurillus - borneensis, cetratus, cheesmanae, consimilis, doesbergi, foliaceus, glaberrimus, gracilis, jacobsoni, longicollis, papuasicus, pumilus, superbus; in Aneurosoma - dissimile; in Aneurus - septentrionalis; in Aradus - dignatus; in Arbanatus - asiaticus, loriae; in Brachyrhynchus - affinis, amplicollis, andamanensis, angolensis, armigerus, australis, bergrothi, bergrothianus, bhoutanensis, breuiceps, burmensis, confectus, confusus, consimilis, crenatus, dentipes, discrepans, dispar, duboisi, elegans, exarmatus, funebrus, furcatulus, furcatus, germari, gracilicornis, granos us, hospidus, hoberlandti, horridus, hsiaoi, incisus, incognitus, insignis, intermedius, javanensis, kachenensis, kerzhneri, lindemannae, longicornis, longirostris, luberoensis, luzonicus, machadoi, madagascariensis, mauricii, membranaceus, micronesicus, monedulus, mario, ouerlaeti, parallelus, pauper, philippinensis, piliferus, poriaicolus, projectus, quadridentatus, quadrispinosus, rossi, rugosus, scrupulosus, serratus, similis, solomonensis, spinipes, stolidus, subinermis, subtriangulus, sulcatus, sulcicornis, sumatrensis, taiwanicus, teter, thailandicus, triangulus, tristis, urijdaghi; in Breviscutaneurus - breviscutatus, helenae, madagascariensis, medioscutatus; in Burgeonia - burgeon, dilatatus, froidebisei, intermedius, kormileui, madagascariensis, maynei, paruus, schoutedeni, usingeri; in Chiastoplonia - pusio; in lralunellus - aibonitensis, bergi, bispinosus, boliuianus, carioca, costariquensis, flavomaculatus, ftitzi, gallicus, leptocerus, longicornis, marginalis, monrosi, plaumanni, politus, sahlbergi, simulans, subdipterous, tenuis, westwoodi, wygodzinsky; in Miraradus - foliaceus, himalayensis, mirabilis, oeruendetes; in Neoproxius - amazonicus, carioca, costariquensis, gypsatus, incaicus, lindemannae, magdalenae, nicaraguensis, palliatus, panamensis, personatus, peruuianus, schwarzii; in Nesiaptera - denticulata, gibbosa, ouata, rotundata, tuberculata, zimmermani; in Nesoproxius - angulatus, constrictus, gracilis, hexagonalis, malayensis, minutus, punctulatus, vietnamensis, yoshimotoi; in Neuroctenus - ghesqueri; in Oreossa - insignis; in Quilnus - amurensis, breuirostris, discedens, heidemanni, niger, nigrinus, oregonicus, paruicollis, subsimilis, usingeri. Three new species names are proposed: Brachyrhynchus pauper for the preoccupied Mezira modesta Kormilev, 1972; Mezira uicina for the preoccupied Mezira proxima Kormilev, 1982; and Mezira doesburgi for the preoccupied Mezira surinamensis Kormilev, 1974. Five new species-synonymys are made: Aradus centriguttatus as a junior synonym of Aradus similis; Mezira jacobsoni as a junior synonym of Daulocoris cornigerus; Mezira modesta as a junior synonym of Brachyrhynchus membranaceus; Neuroctenus breuicornis as a junior synonym of Neuroctenus ater; Notoplocaptera malaisei as a junior synonym of Zoroaptera malaisei. Four new emendations of gender endings are proposed for the species name "halaszfyi": Artabanus halaszfyae, Chelysosoma halaszfyae, Ctenoneurus halaszfyae, Mezira halaszfyae.
The Gottfried sum-rule violation reported by the New Muon Collaboration was interpreted as an indication for a flavor asymmetry of the sea quark in the nucleon. We investigate the alternative possibility that isospin symmetry between the proton and the neutron is breaking. We examine systematically the consequences of this possibility for several processes, namely, neutrino deep inelastic scattering, the charged pion Drell-Yan process, the proton Drell-Yan process, and semi-inclusive deep inelastic scattering, and conclude that a decision between the two alternative explanations is possible.
