The paper deals with questions of extending the scope of justice to environmental prob- lems. In investigating the available political and environmental philosophies the author comes to the following conclusion: for the proper theoretical handling of environmental problems ethics integrating social and environmental aspects should be worked out.

A 2020-as évektől nagy kihívásokkal találta magát szemben az autóipar. A Covid-19 jelentősen megváltoztatta az ellátási láncok működését, az addig kiszámítható beszerzési és elosztási rendszerek teljes egészében bizonytalanná váltak. Szükség volt a logisztikai folyamatok áttervezésére. Az ezt megelőző időszakban jól alkalmazható logisztikai módszerek - (JIT, JIS, ABC elemzésen alapuló beszerzési stratégiák) amelyek az iparra jellemző sajátosággal rendelkeztek és segítették a Lean alapú gyártást a készletszintek csökkentését és a pontos szállításokat - felhasználásukat tekintve a változó gazdasági környezet miatt hatékonyságuk csökkent és vagy átalakult. 2022-ben az Orosz-Ukrán háború és az azt követő időszak energiaválsága újabb feladatok elé állította az autóipari logisztikai rendszereket. Ezen tényezők miatt a logisztikai folyamatokban jelentős átalakulások következtek be, hiszen az állandóan változó gazdasági környezet, a hektikusan alakuló energiaköltségek és a munkabérek jelentős növekedése a stratégiai szint mellett az tervezési és operatív folyamatok pontos és naprakész mérését és kontrollját tette szükségessé. A gazdasági teljesítő képesség mellett megjelentek olyan a túlélést biztosító tulajdonságok az autóipari vállalkozásoknál, mint a rugalmasság, az alkalmazkodó képesség, a modularitás vagy a nagyobb rendszerekbe való kapcsolódás és beágyazódottság képessége. Mindezen tulajdonságok megléte már alapvető szükséglet az autóipari folyamatok zavartalan működéséhez. A korábban működő logisztikai szabályokat újra kellett a vállalkozásoknak gondolni, így a Kühne+Nagel Kft-nek is, mint logisztikai szolgáltatónak tanulva az elmúlt 3 év gazdasági változékonyságaiból másfajta módon kell meghozni a stratégiai döntéseit. 2023-ban újabb hosszú távú kihívások elé állították az autóipari beszállítókat és logisztikai szolgáltatókat, hiszen az elektromos autóipari folyamatokra való felkészülés és átállás teljesen más alkatrészek és készletezési rendszerek valamint beszállítók megjelenését hozta magával.

Growing global social and environmental problems draw attention to rethinking traditional marketing approaches. There are many signs of social and environmentally conscious marketing being now rediscovered. The main objectives of our comprehensive research project on social marketing were to find out how values influence general environmental behaviour. In order to achieve our objectives, we conducted a questionnaire survey with a representative sample of 501 respondents in 2011 in Hungary. Security proved to be the most important, extremely important value, which supports pro-environmental behaviour. Excitement, followed by being well respected and fun and enjoyment in life, all of which are negatively correlated by pro-environmental behaviour, are the least important values in Hungary. Additionally, we found that more than the half of the Hungarian population usually lived green. However, only weak correlations were found between environmentally conscious behaviour and value items. Since the direct influence of values on GEB is only weak, more variables (e.g. attitudes) are needed when modelling someone's pro-environmental behaviour.DOI: http://dx.doi.org/10.5755/j01.em.17.1.2278

Well defined periodic light curves are obtained in six cases allowing us to derive rotational periods, a notable increase in the number of Centaurs with known rotational properties. The low amplitude light curves of (471931) 2013 PH44 and (250112) 2002 KY14 can be explained either by albedo variegations, binarity or elongated shape. (353222) 2009 YD7 and (514312) 2016 AE193 could be rotating elongated objects, while 2017 CX33 and 2012 VU85 are the most promising binary candidates due to their slow rotations and higher light curve amplitudes. (463368) 2012 VU85 has the longest rotation period, P = 56.2 h observed among Centaurs. The P > 20 h rotation periods obtained for the two potential binaries underlines the importance of long, uninterrupted time series photometry of solar system targets that can suitably be performed only from spacecraft, like the Kepler in the K2 mission, and the currently running TESS mission. © 2020 The Authors ; The research leading to these results has received funding from the European Union 's Horizon 2020 Research and Innovation Programme, under Grant Agreement No. 687378 ; from the K-125015 , PD-116175 , PD-128360 , and GINOP-2.3.2-15-2016-00003 grants of the National Research Development and Innovation Office (NKFIH, Hungary); and from the LP2012-31 and LP2018-7/2019 Lendület grants of the Hungarian Academy of Sciences .

Context. Thanks to the Gaia mission, it will be possible to determine the masses of approximately hundreds of large main belt asteroids with very good precision. We currently have diameter estimates for all of them that can be used to compute their volume and hence their density. However, some of those diameters are still based on simple thermal models, which can occasionally lead to volume uncertainties as high as 20–30%. Aims. The aim of this paper is to determine the 3D shape models and compute the volumes for 13 main belt asteroids that were selected from those targets for which Gaia will provide the mass with an accuracy of better than 10%. Methods. We used the genetic Shaping Asteroids with Genetic Evolution (SAGE) algorithm to fit disk-integrated, dense photometric lightcurves and obtain detailed asteroid shape models. These models were scaled by fitting them to available stellar occultation and/or thermal infrared observations. Results. We determine the spin and shape models for 13 main belt asteroids using the SAGE algorithm. Occultation fitting enables us to confirm main shape features and the spin state, while thermophysical modeling leads to more precise diameters as well as estimates of thermal inertia values. Conclusions. We calculated the volume of our sample of main-belt asteroids for which the Gaia satellite will provide precise mass determinations. From our volumes, it will then be possible to more accurately compute the bulk density, which is a fundamental physical property needed to understand the formation and evolution processes of small Solar System bodies. ; The research leading to these results has received funding from the European Union's Horizon 2020 Research and Innovation Programme, under Grant Agreement no 687378 (SBNAF).
