The strong Lefschetz property of monomial complete intersections in two variables
In this paper we classify the monomial complete intersection algebras, in two
variables, and of positive characteristic, which has the strong Lef- schetz
property. Together with known results, this gives a complete classi- fication
of the monomial complete intersections with the strong Lefschetz property
Subalgebras generated in degree two with minimal Hilbert function
What can be said about the subalgebras of the polynomial ring, with minimal
or maximal Hilbert function? This question was discussed in a recent paper by
M. Boij and A. Conca. In this paper we study the subalgebras generated in
degree two with minimal Hilbert function. The problem to determine the
generators of these algebras transfers into a combinatorial problem on counting
maximal north-east lattice paths inside a shifted Ferrers diagram. We
conjecture that the subalgebras generated in degree two with minimal Hilbert
function are generated by an initial Lex or RevLex segment.Comment: To appear in Mathematica Scandinavic
Toric and non-toric Bayesian networks
In this paper we study Bayesian networks from a commutative algebra
perspective. We characterize a class of toric Bayesian nets, and provide the
first example of a Bayesian net which is proved non-toric under any linear
change of variables. Concerning the class of toric Bayesian nets, we study
their quadratic relations and prove a conjecture by Garcia, Stillman, and
Sturmfels for this class. In addition, we give a necessary condition on the
underlying directed acyclic graph for when all relations are quadratic
Meditation and the Inner Life of Todayâs Educator
This project stemmed from the researcherâs feeling stress as a new teacher and the need for self-care. The study is contextualized and the theoretical frameworks include meditation and mindfulness. (Venditti et al., 2020). Teaching is a stressful profession and many teachers experience daily stresses that can often lead to teacher burnout. When teachers are stressed, their ability to effectively teach and connect with students is diminished. This is further exacerbated by the fact that educators are teaching through the unprecedented times of COVID-19. Meditation and mindfulness are universal and free tools that educators can use to decrease stress and increase joy in their own lives.
This study used a mixed methods approach to the study in a group setting with 8 educational professionals who met weekly for 6 weeks. The findings of this research indicate a universal sense that these educators are feeling lonely and seeking community, that there are high levels of criticism around meditation and self-care, and that the impact of participants in group mediation resulted in participants engaging in activities beyond the core practice of the group. This has important implications for time and resources for teachers to gather and for community practices that focus on meditation or other self-care practices
"Det skall löna sig att plugga"  En undersökning av processerna bakom det nya betygsförslaget (Ds 2008:13), samt tidigare betygsskiften, utifrÄn aspekter sÄsom politiska ideologier.
Syfte
I detta arbete tas en nÀrmare till pÄ Jan Björklunds förslag pÄ ny betygsskala (Ds 2008:13) samt hur den process
som ligger bakom förslaget har sett ut. Syftet Àr att utifrÄn aspekter som bland annat politiska ideologier och
kunskapssyner studera vad som lett fram till förslaget.
HuvudfrÄga
Hur mycket och pÄ vilket sÀtt pÄverkar politiska ideologier i det nya och tidigare betygsystembyte?
Metod och material
En historisk tillbakablick med fokus pÄ betyg och de olika betygsreformer som skett i Sverige genomförs genom
en litteraturstudie. Vidare har Àven olika propositioner, betÀnkande samt dokument frÄn Statens offentliga
utredningar kring betygsfrÄgan studerats men ocksÄ artiklar av betyg- och bedömningsforskare har granskats.
DÀrefter utfördes en kvalitativ undersökning i form av intervjuer med betyg- och bedömningsforskare samt en
politisk sakkunnig frÄn den nu sittande regeringen(2008).
Resultat
I analys och resultat genomförs en jÀmförande analys utifrÄn vÄra kvalitativa intervjuer. Slutsatsen Àr att
politiska ideologier tydligt pÄverkar beslut vid betygsystembyten. Genom historien kan man se att inflytande i
debatten flyttats frÄn forskare till allmÀnheten, men att det ÀndÄ Àr politikerna som tar det slutgiltiga beslutet i
processen.
Betydelse för lÀraryrket
Det Àr viktigt att som lÀrare ha kunskap i vilka olika kunskapssyner och politiska influenser som styr och
pÄverkar i skolreformer. Det Àr viktigt för att ha en medvetenhet och ett kritiskt förhÄllningssÀtt till olika
styrdokumen
Gorenstein rings generated by strongly stable sets of quadratic monomials
We characterize all Gorenstein rings generated by strongly stable sets of
monomials of degree two. We compute their Hilbert series in several cases,
which also provides an answer to a question by Migliore and Nagel
