selektywno

Selektywno is a term encountered in Polish-language texts to refer to the property or action of being selective. In standard Polish, the noun is selektywność and the adverb is selektywnie; "selektywno" is not a standard inflected form but may appear in technical shorthand, multilingual borrowings, or as part of compound terms. The concept denotes the preference for certain targets, outcomes, or components over others.

Etymology: It derives from Latin selectivus via French sélectif and the Polish root selektyw-, with related forms used in various technical contexts.

Applications: In pharmacology, selectivity describes a drug's higher affinity for a specific receptor or transporter, yielding targeted effects with reduced off-target activity. In chemistry and materials science, selectivity refers to preferential reaction, binding, or separation of a substance from a mixture, often quantified by a selectivity factor or distribution coefficient. In ecology and physiology, selective processes influence which traits persist or which resources are chosen. In cognitive science and psychology, selective attention refers to narrowing perception to particular stimuli.

In information technology and media, selective filtering and targeted dissemination shape what information is processed or delivered. High selectivity is generally valued for efficiency and safety, but excessive selectivity can lead to bias or reduced diversity.
