The aim of this paper is to suggest a framework for research on non-native bilingualism (NNB) in Poland (www.nnbproject.eu). The term non-native bilingualism refers to a situation where, in a Polish family residing in Poland, one or both parents resolve to permanently use a non-native language when communicating with their child or children. The research problems of the “NNB in Poland” project are discussed briefly; the author explains the origins of the term „non-native bilingualism”, defines other terms used in the research, presents the case for and against NNB and collates the common beliefs with the results of contemporary research on bilingualism, including non-native bilingualism.

Globally more than 5.2 billion hectares of farming fields are damaged through erosion, salinity and soil deterioration. Many salt stress tolerant bacteria have plant growth promoting (PGP) characteristics that can be used to overcome environmental stresses. Isolation and screening of salt-tolerant endophytes from Salicornia brachiata were achieved through surface sterilization of leaves followed by cultivation on 4% NaCl amended media. Performance of isolates towards indole-3-acetic acid (IAA) production, phosphate solubilization, ACC deaminase activity, ammonia production, siderophore production and stress tolerance were determined. On the basis of the highest plant growth promoting activity, SbCT4 and SbCT7 isolates were tested for plant growth promotion with wheat and maize crops. In the present study, a total of 12 morphologically distinct salt-tolerant endophytic bacteria was cultured. Out of 12 isolates, 42% of salt-tolerant endophytes showed phosphate solubilization, 67% IAA production, 33% ACC-deaminase activity, 92% siderophore production, 41.6% ammonia production and 66% HCN production. A dendrogram, generated on the basis of stress tolerance, showed two clusters, each including five isolates. The bacterial isolates SbCT4 and SbCT7 showed the highest stress tolerance, and stood separately as an independent branch. Bacterial isolates increased wheat shoot and root dry weights by 60–82% and 50–100%, respectively. Similarly, improved results were obtained with maize shoot (27–150%) and root (80–126%) dry weights. For the first time from this plant the bacterial isolates were identified as Paenibacillus polymyxa SbCT4 and Bacillus subtilis SbCT7 based on phenotypic features and 16S rRNA gene sequencing. Paenibacillus polymyxa SbCT4 and B. subtilis SbCT7 significantly improved plant growth compared to non-inoculated trials.

This article reflects on key concepts of historical thinking proposed by doctoral students and young researchers. Established concepts such as the social role of history, professional historian and (imagined) space are still important to the new generation of historians. At the same time, some new concepts are emerging, such as political exhumations, mass graves, motion, embodied historical research, ahistorical memory politics, websites as historical sources, critical heritage studies and heritagisation, treason, preposterous history – an idea taken from Mieke Bal, and “Supreme Peace” – a notion drawn from the Chinese philosophy of history. To interpret these concepts, I build word clouds as a way of creating knowledge involving non‑human factors (algorithms) while enabling speculative interpretations of the relations between words. The idea of a secure past comes to the fore and I therefore examine whether historical security and being secure in history could be considered important elements of interdisciplinary security studies.
