We have studied the properties of low-lying ${}^{18}\mathrm{F}+p$ resonances as excited states in ${}^{19}\mathrm{Ne}.$ Three new levels been found range $0<~{E}_{\mathrm{c}.\mathrm{m}.}<~1 \mathrm{MeV}$ just above threshold, and partial decay widths isospin-mirror connections are suggested to known ${}^{19}\mathrm{F}$ for each nine this energy range. The these used calculate reaction rate ${N}_{A}〈\ensuremath{\sigma}v〉$ ${}^{18}\mathrm{F}(p,\ensuremath{\gamma}{)}^{19}\mathrm{Ne}$...

We used the $^{16}\mathrm{O}$${(}^{3}$He,n${)}^{18}$Ne, $^{12}\mathrm{C}$${(}^{12}$C${,}^{6}$He${)}^{18}$Ne, and $^{20}\mathrm{Ne}$(p,t${)}^{18}$Ne reactions to study $^{18}\mathrm{Ne}$ states up an excitation energy of 10 MeV, with emphasis on levels corresponding $^{14}\mathrm{O}$(\ensuremath{\alpha},p${)}^{17}$F $^{17}\mathrm{F}$(p,\ensuremath{\gamma}${)}^{18}$Ne resonances that could strongly affect these reaction rates in hot stellar environments. Excitation energies, widths, absolute...

A choice function is list rational(izable) if there a fixed such that for each set, successive comparison of the alternatives by following retrieves chosen alternative. We extend formulation rationality to stochastic setup. say two are related path independence condition violated between these alternatives. show random rational and only this relation acyclic. Our characterization deterministic functions follows as corollary. By using characterization, we relate two-stage procedures.

A choice rule with affirmative action decides on the recipients of a limited number identical objects by reconciling two objectives: respecting priority ordering over applicants and supporting minority group. We extend standard formulation problem incorporating type function introduce monotonicity axioms how should respond to variations in these parameters. show that monotonic substitutable rules are ones admit bounded reserve representation. As prominent class satisfy axioms, we...

Abstract In several matching markets, to achieve diversity, agents' priorities are allowed vary across an institution's available seats, and the institution is let choose agents in a lexicographic fashion based on predetermined ordering of called ( capacity‐constrained ) choice rule . We provide characterization rules deferred acceptance mechanisms that operate structure under variable capacity constraints. discuss some implications for Boston school system show our analysis can be helpful...

In several matching markets, in order to achieve diversity, agents’ priorities are allowed vary across an institution’s available seats, and the institution is let choose agents a lexicographic fashion based on predetermined ordering of called choice rule. Lexicographic rules have been particularly useful achieving diversity at schools while allocating school seats. We provide characterization rules, which reveals their distinguishing properties from other plausible rules. Moreover, we study...

Each capacity-filling and substitutable choice rule is known to have a maximizer-collecting representation: There exists list of priority orderings such that from each set includes more alternatives than the capacity, union orderings’ maximizers. We introduce notion critical constructively prove number sets for determines its smallest-size representation. show responsive rules require maximal in their representations among all rules. also analyze which equals capacity. if capacity greater...

Dogan and Yildiz introduce analyze the pro-con model that is inspired by Franklin’s prudential algebra. Consider an agent who endowed with two sets of orderings: pro- con-orderings. For each choice set, if alternative top-ranked a pro-ordering (con-ordering), then this pro (con) for choosing alternative. The more pros than cons chosen from set. Each ordering may have weight reflecting its salience. In case, probability equals difference between total weights cons. Although, additive similar...

Energy-integrated one- and two-proton transfer cross sections fusion excitation functions have been measured for at energies near the Coulomb barrier. As in previous results with projectiles, anomalous dependence of probability on distance closest approach is observed only slightly above Measured show sub-barrier enhancement similar to that other systems. Coupled-channel calculations including form factors extracted from measurements come closer data produce full .

The aim of this study is to explore the levels workers' willingness unionize, their perceptions about substitution effect and suppression effect, relationship between effects.To do so, a survey was conducted among 215 workers.Descriptive statistics were used determine mentioned levels, multiple linear regression analysis utilized reveal relationship.At end research, we discover that there high level low workers stronger tendency on robustly predicted by effect.

We present a characterization of the Luce rule in terms positivity and new choice axiom called odds supermodularity that strengthens regularity axiom. This illuminates connection goes unnoticed sheds light on behavioral underpinnings its extensions from different perspective. show per se characterizes structured extension accommodates zero probability choices. identify random model characterized via stochastic counterpart Plott (1973)’s path independence axiom, which supermodularity.

Büyüyen bir ekonomi ve genç işgücüne sahip Türkiye’de mesleki eğitim oldukça önemli konudur. Aktif işgücü politikalarının uygulayıcısı olan İŞKUR, 2008 Ekonomik Krizinden sonra faaliyetlerine hız vermiştir. Aslında yapısal problemleri çözmek için uygulanan bu faaliyetler ilk defa kriz döneminde hızlandırılmış olsa da doğru yaklaşımla sonrası dönemde de artırılarak devam ettirilmiştir. Yaşanan süreçte alınan geri bildirimler çerçevesinde çeşitli uygulama değişikliklerine gidilmiştir. Yapılan...

This paper is an attempt to investigate boundedly rational choice theories based on the structure of axioms that these satisfy. We propose regularities classify according underlying axioms. Based regularities, we characterize rendering characterizations are as simple theory. Then, and illustrate a method identify behavioral differences distinguish theory in given family theories.
