Społeczny ethos uczonych a procesy "zurzędniczania" nauki

2018

Niniejszy artykuł stawowi wynik namysłu nad zagadnieniem społecznego ethosu uczonych w kontekście dominacji ujmowania nauki w perspektywie ilościowej. Przedstawione stanowiska dotyczące ról przypisywanych luminarzom nauki są wybraną reprezentacją podejść klasycznych nauki polskiej. Uzupełniają się zarówno w kontekście instytucjonalnym (prof. K. Twardowski), jak i społecznym (prof. F. Znaniecki). Pozostają również w ścisłym związku z uniwersalnym przesłaniem zawartym w rocie ślubowania składanego przez pracowników nauki podczas uroczystości promocji doktorskiej, czyli na progu ich inicjacji akademickiej. Intencją zestawienia klasycznych podejść do ról i wynikającego z nich ethosu uczonych z …

Dihydrogen Activation by Antiaromatic Pentaarylboroles

2010

Facile metal-free splitting of molecular hydrogen (H2) is crucial for the utilization of H2 without the need for toxic transition-metal-based catalysts. Frustrated Lewis pairs (FLPs) are a new class of hydrogen activators wherein interactions with both a Lewis acid and a Lewis base heterolytically disrupt the hydrogen−hydrogen bond. Here we describe the activation of hydrogen exclusively by a boron-based Lewis acid, perfluoropentaphenylborole. This antiaromatic compound reacts extremely rapidly with H2 in both solution and the solid state to yield boracyclopent-3-ene products resulting from addition of hydrogen atoms to the carbons α to boron in the starting borole. The disruption of antiar…

Dire institutionnel et espaces de langage - le cas de l'Algérie - Essai d'une sémio-didactique

1992

This thesis is 1) an discourse analysis of the institution' texts (Algeria, in the eighties) + analysis of the young people in secondary school (part I) ; 2) a semiotic analysis of spaces in Algeria (country, village, secondary school). The results : we showed many contraints in a collective speech, through 2 dominant themas : time, action ; and 2 recessive themas : subject (speaker), mirror. So, education and didactic perspective are useful.

The development of work values during the transition to adulthood : A two-country study

2017

This study addresses the development of work values—the desired characteristics of one's current or future job—during young adulthood. Using two panel studies from Germany (N = 2506) and Finland (N = 1326), we investigated (a) mean-level and rank-order change and stability in work values across three biennial waves (age 20/21 to age 25/26); and (b) the influence of stable background characteristics as well as of major transitions in family and work roles on inter-individual differences and intra-individual changes in work values. Latent measurement models with three work value dimensions showed good fit in both countries: extrinsic (importance of job security and material rewards), intrinsi…

Personāla atlases speciālista personības iezīmju un kontroles lokusa saistība ar kandidātu uzrunāšanas veidiem

2020

Uzņēmēju lokā popularitāti guva tendence vairāk darbā pieņemt pieredzējušus speciālistus, nekā jauniešus vai cilvēkus bez pieredzes konkrētā nozarē. 2014. gada rakstā (Blacksmith & Poeppelman, 2014) tika minēts, ka šī tendence parādījās pēc sociālo tīklu ieviešanas, radot izmaiņas arī personāla atlases metodēs. Pieredzējuši speciālisti, lielākoties, jau ir nodarbināti un aktīvi darbu nemeklē. Līdz ar to kļuva nozīmīgāks kandidātu uzrunāšanas posms. Tā mērķis ir panākt, lai atbilstoši kandidāti ir ieinteresēti atnākt uz interviju. Personāla piesaiste kļuva līdzīga pārdošanai. Šajā darbā tiek izskatīti 6 kandidātu uzrunāšanas veidi jeb darba sludinājuma izvietošana darba meklēšanas portālā, p…

Model of hydrocarbons transport through the porous ground media

2014

Dispersion model of hydrocarbons transport in porous media has been presented. Mathematical description of this process allows to estimate whether the menace of ground waters can occur as a result of hydrocarbons transport through the soil. The convection term in the mass transport equation is taken into account due to the higher velocity of propagation in vertical direction. Additionally, introduction to the balance equation the biosorption link allows to take into account microorganisms influence on impurities concentration, especially on heavy oils derived compounds. To verify the theoretical model series of the experiment in the soil filter has been carried out.

Influence of bioremediation stimulators in soil on development of oat seedlings (Avena sativa) and their aminopeptidase activity

2015

Dobór technik bioremediacji jest bardzo ważny w oczyszczaniu gleby skażonej substancjami ropopochodnymi, która ma być wykorzystywanej rolniczo. Prezentowane wyniki wskazują, że na rozwój siewek owsa większy wpływ ma stosowana metoda bioremediacji niż poziom zanieczyszczenia węglowodorami. Z zastosowanych technik najbardziej przyjazne dla wegetacji owsa były te, w których wykorzystywano szczepionkę drożdżową.

The Particularities of Pharmaceutical Care in Improving Public Health Service during the COVID-19 Pandemic

2021

Nowadays, humanity is confronted with one of the most difficult challenges. Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was identified for the first time in Hubei, China in December 2019 and produced the COVID-19 pandemic, a devastating disease that led to many complications and deaths. The authorities and the global healthcare system have been alerted regarding the prevention and treatment of this pathology. Even though worldwide quarantine was declared, health care professionals, including pharmacists, have been at the frontline in this war. Since the beginning of the pandemic, the authorities relied on the involvement of the community, hospital, or clinical pharmacists i…
