Ontslag op staande voet. Dringende reden. Diefstal. Alle omstandigheden van het geval.

Artikel 7:677 lid 1 BW regelt het ontslag op staande voet (hierna: o.o.s.v.). Uit deze bepaling zijn drie voorwaarden af te leiden, waaraan zal moeten zijn voldaan wil het o.o.s.v. rechtsgeldig zijn gegeven. Zo moet er allereerst sprake zijn geweest van een dringende reden, moet er, in de tweede plaats een onverwijlde opzegging van de arbeidsovereenkomst hebben plaatsgevonden, terwijl, in de derde plaats, de dringende reden voor het o.o.s.v. gelijktijdig aan de werknemer moet zijn medegedeeld. In het hier te annoteren arrest staat de vraag centraal wanneer sprake is van een ‘dringende reden’. De literatuur spreekt in dit verband wel over de ‘objectiviteit’ (is er naar objectieve maatstaven sprake van een dringende reden?) en ‘subjectiviteit’ (is in dit concrete geval ook sprake van een dringende reden?, hetgeen onder meer kan blijken uit de onverwijldheid) van de dringende reden (zie C.J. Loonstra & W.A. Zondag, Arbeidsrechtelijke Themata, Den Haag: BJu 2010, p. 426). Het arrest handelt over het o.o.s.v. van een medewerker van de Bijenkorf die geweigerd was in het kader van een uitverkoopactie twee artikelen meer van de Bijenkorf af te nemen dan de vijf toegestane artikelen (tegen betaling van € 10), en vervolgens – daarbij een kennelijk wat minder door de Bijenkorf op prijs gestelde interpretatie gevende aan het begrip ‘Doldwaze Dagen’ – deze twee artikelen alsnog zelf (tegen betaling van € 0) afnam

Resonant cancellation of off-resonant effects in a multilevel qubit

Off-resonant effects are a significant source of error in quantum computation. This paper presents a group theoretic proof that off-resonant transitions to the higher levels of a multilevel qubit can be completely prevented in principle. This result can be generalized to prevent unwanted transitions due to qubit-qubit interactions. A simple scheme exploiting dynamic pulse control techniques is presented that can cancel transitions to higher states to arbitrary accuracy.Comment: 4 pages, Revtex, submitted for publicatio

"Plantar pro gasto": a importância do autoconsumo entre famílias de agricultores do Rio Grande do Sul.

O artigo discute a valoração e importância da produção para o autoconsumo na reprodução social das unidades familiares e caracteriza os alimentos autoconsumidos. Vale-se da pesquisa "Agricultura Familiar, Desenvolvimento Local e Pluriatividade" (UFRGS/UFPel/ CNPq-2003) que propiciou a formação de um banco de dados com informações sobre a dinâmica da agricultura familiar em quatro regiões distintas da geografia gaúcha, suas fontes e tipos de renda, entre estas o autoconsumo. Trazer este debate significa retomar um tema pouco discutido até então, e que, embora marginalizado ou considerado sem importância, desenvolve importante papel como renda não monetária, fortalece a segurança alimentar e adentra esferas da sociabilidade e identidade social. Além da introdução, apresenta-se o papel do autoconsumo na agricultura familiar, o cálculo da produção para o autoconsumo, discussão dos objetivos e resultados, e considerações finais. Os resultados demonstram que a produção para o autoconsumo é uma estratégia recorrente pelas unidades familiares e se diferencia de acordo com a dinâmica da agricultura familiar. Diferença esta expressa em valores relativos (%) e no número de estabelecimentos pertencentes a estratos diferenciados de autoconsumo, e pouco nos tipos de alimentos produzidos para este fim, observando-se uma homogeneidade dos hábitos alimentares

When work keeps us apart: a thematic analysis of the experience of business travellers

Whilst business travel is deemed important for organizational success and economic outcomes, little is known about the actual process of business travelling from the perspective of individuals who undertake such travel on a regular basis. Thus the current qualitative study examined how business travellers (three women and eight men) attempt to find a balance between work and family, by focusing on how time together and time apart are experienced. The results can be interpreted and framed within work/family border theory in that business travellers’ borders are less defined and less permeable, thus requiring them to border-cross more frequently. This necessitates a process of negotiation with key border-keepers (their spouse/partner). Business travellers also undertake compensatory behaviours to make up for their time away from family. In order to find a work/family balance they go through a process of adapting, negotiating and tailoring their lives around their work commitments to alleviate work-life conflict

Nutrient deficiencies in apple plants (Pyrus malus L.)

O ensaio foi conduzido com macieiras 'Ohio Beauty' com 1 ano, cultivadas em vaso para se verificar sintomas e níveis de deficiências de N, P, K, Ca, Mg, S e B. Conclui - se que: os níveis de nutrientes em folhas sadias e com sintomas de deficiência são: N -2,22 e 1,53%, P - 0,17 e 0,05%; K - 1,32 e 0,22%, Ca - 0,9¹* e 0,52%, Mg - 0,37 60,06%, S - 0,18 e 0,08%, B - 62 e 2k ppm. Os níveis de deficiência em folhas,a fome oculta" são: N - 1,74%, P - 0,07%, K - 0,30%, Ca - 0,65%, Mg - 0,09%, S - 0,09%, B-33ppm.A trial was carried out with one year old 'Ohio Beauty apples (grafted on 'Doucin'), grown on sand cu1ture, receining nutrient solutions lacking the following nutrients at the time: N, P, K, Ca, Mg, S, and B. The main conclusions are as follows: as the adequate and inadequate levels from leaf analysis were, respectively: N -2.22 and 1.53%, P - 0,17 and 0.05%, K - 1.32 and 0.33%; Ca -0.9.4 and 0.52%, Mg - 0.37 and 0.06%; S -0.18 and 0.08%; B -62 and 2k ppm

Quasars and their host galaxies

This review attempts to describe developments in the fields of quasar and quasar host galaxies in the past five. In this time period, the Sloan and 2dF quasar surveys have added several tens of thousands of quasars, with Sloan quasars being found to z>6. Obscured, or partially obscured quasars have begun to be found in significant numbers. Black hole mass estimates for quasars, and our confidence in them, have improved significantly, allowing a start on relating quasar properties such as radio jet power to fundamental parameters of the quasar such as black hole mass and accretion rate. Quasar host galaxy studies have allowed us to find and characterize the host galaxies of quasars to z>2. Despite these developments, many questions remain unresolved, in particular the origin of the close relationship between black hole mass and galaxy bulge mass/velocity dispersion seen in local galaxies.Comment: Review article, to appear in Astrophysics Update

Weak lensing, dark matter and dark energy

Weak gravitational lensing is rapidly becoming one of the principal probes of dark matter and dark energy in the universe. In this brief review we outline how weak lensing helps determine the structure of dark matter halos, measure the expansion rate of the universe, and distinguish between modified gravity and dark energy explanations for the acceleration of the universe. We also discuss requirements on the control of systematic errors so that the systematics do not appreciably degrade the power of weak lensing as a cosmological probe.Comment: Invited review article for the GRG special issue on gravitational lensing (P.
