In [13], Migliore–Miró-Roig–Nagel show that the Weak Lefschetz property can fail for an ideal I ⊆ K[x1, . . . , x4] generated by powers of linear forms. This is in contrast to the analogous situation in K[x1, x2, x3], where WLP always holds [16]. We use the inverse system dictionary to connect I to an ideal of fat points, and show that failure of WLP for powers of linear forms is connected to t...

let $l$ be a completely regular frame and $mathcal{r}l$ be the ‎ring of continuous real-valued functions on $l$‎. ‎we show that the‎ ‎lattice $zid(mathcal{r}l)$ of $z$-ideals of $mathcal{r}l$ is a‎ ‎normal coherent yosida frame‎, ‎which extends the corresponding $c(x)$‎ ‎result of mart'{i}nez and zenk‎. ‎this we do by exhibiting‎ ‎$zid(mathcal{r}l)$ as a quotient of $rad(mathcal{r}l)$‎, ‎the‎ ‎...

This study aimed to characterize midwives according to current concepts among health professionals and to identify the ideological premises underlying proposals for their training. Data from interviews with nine midwives, nurses, and physicians were interpreted using discourse analysis. The resulting empirical categories were "The Situation of Maternity Care in Brazil", "The Ideal (or Necessary...

This paper studies the notion of ability and its relation with the notion of action in a multi-agent context. It introduces the distinction between two notions respectively called “theoretical ability” and “ability”. The main contribution of this paper is a model of these notions in the Situation Calculus.

Infraocclusion is a clinical situation of teeth with occluding surfaces below the plane of occlusion. Treatment of infraocclusion depends on the severity of the situation. This article shows the results of a non-invasive prosthetic approach applied to a young female patient having two infraoccluded premolars. The choice of treatment was to raise the level of these teeth by closing the space wit...

â  the aim of this study was to investigate the postgraduate students' views regarding their current and desired participation in curriculum development and compare their views with the curriculum experts' opinions. this study is a descriptive-analytical and both qualities and quantitative methods were used/ the population consisted of two groups. the first group consists of all curri...

Agent supervision is a form of control/customization where a supervisor restricts the behavior of an agent to enforce certain requirements, while leaving the agent as much autonomy as possible. This is done in a setting based on the situation calculus and a variant of the ConGolog programming language that is situation-determined, i.e., the remaining program is a function of the action performe...

This paper introduces GLAM, a system based on situation calculus and meta-rules, which is able to provide adaptation by means of selection of actions. It is primarily designed to provide adaptive navigation. The different levels of conception, related to different aspects of the available metadata, are split in different layers in GLAM, in order to ease the conception of the adaptation system a...
