Older workers and learning in industrial activities: when objects and personal senses matter
The issue of vocational learning (VL) for older workers (OWs) has become pivotal in
European regions with an ageing workforce and facing economic changes and pressure
to innovate. European Union policies recognize the value of formal, non-formal and
informal learning to enhance workersâ skills, but report low participation of OWs in
continuing formal VL.
I contend that EU documents conceptualize learning according to a âcognitivistâ view
and motivation as an individual endeavour, failing to acknowledge OWsâ subjectivities
and working activities in providing the context for the development of their motives for
learning.
I adopt Cultural-Historical Activity Theory (CHAT) to direct the attention to the OWsâ
subjectivities and their personal relationships with their objects of activities (work).
CHAT allows subjectivities and activities to be brought together in a holistic framework.
To illuminate the different ways in which objects influence motivation and learning, I
introduce sociological strategies of production as objects of industrial activities and
identify two radically different models as mass production and flexible specialization.
Two case studies, based on unstructured interviews with OWs and managers in two
firms representing both production models, provide elements to analyse the interrelation
between OWsâ activities objects and their personal senses of these.
My thesis concludes that:
(i) OWsâ relation with their work contexts, rather than their personal qualities,
influences their engagement in their working practices and leads to the
development of motives for learning;
(ii) strategies of production influence the intensity and richness of OWsâ
workplace learning;
(iii) OWsâ previous and parallel experiences of active roles contribute to the
judgement of the current work and to engagement in this;
(iv) EU policies for VL need to take into account how to support the OWsâ
engagement in their jobs

Evidence of another anthropic impact on iguana delicatissima from the lesser Antilles: the presence of antibiotic resistant enterobacteria
The improper use of antibiotics by humans may promote the dissemination of resistance in wildlife. The persistence and spread of acquired antibiotic resistance and human-associated bacteria in the environment, while representing a threat to wildlife, can also be exploited as a tool to monitor the extent of human impact, particularly on endangered animal species. Hence, we investigated both the associated enterobacterial species and the presence of acquired resistance traits in the cloacal microbiota of the critically endangered lesser Antillean iguana (Iguana delicatissima), by comparing two separate populations living in similar climatic conditions but exposed to different anthropic pressures. A combination of techniques, including direct plating, DNA sequencing and antimicrobial susceptibility testing allowed us to characterize the dominant enterobacterial populations, the an- tibiotic resistant strains and their profiles. A higher frequency of Escherichia coli was found in the samples from the more anthropized site, where multi-drug resistant strains were also isolated. These results confirm how human-associated bacteria as well as their antibiotic-resistance determinants may be transferred to wildlife, which, in turn, may act as a reservoir of antibiotic resistance
Diverse MicroRNAs-mRNA networks regulate the priming phase of mouse liver regeneration and of direct hyperplasia
OBJECTIVES: Adult hepatocytes are quiescent cells that can be induced to proliferate in response to a reduction in liver mass (liver regeneration) or by agents endowed with mitogenic potency (primary hyperplasia). The latter condition is characterized by a more rapid entry of hepatocytes into the cell cycle, but the mechanisms responsible for the accelerated entry into the S phase are unknown. MATERIALS AND METHODS: Next generation sequencing and Illumina microarray were used to profile microRNA and mRNA expression in CDâ1Â mice livers 1, 3 and 6Â h after 2/3 partial hepatectomy (PH) or a single dose of TCPOBOP, a ligand of the constitutive androstane receptor (CAR). Ingenuity pathway and DAVID analyses were performed to identify deregulated pathways. MultiMiR analysis was used to construct microRNAâmRNA networks. RESULTS: Following PH or TCPOBOP we identified 810 and 527Â genes, and 102 and 10Â miRNAs, respectively, differentially expressed. Only 20Â genes and 8Â microRNAs were shared by the two conditions. Many miRNAs targeting negative regulators of cell cycle were downregulated early after PH, concomitantly with increased expression of their target genes. On the contrary, negative regulators were not modified after TCPOBOP, but Ccnd1 targeting miRNAs, such as miRâ106bâ5p, were downregulated. CONCLUSIONS: While miRNAs targeting negative regulators of the cell cycle are downregulated after PH, TCPOBOP caused downregulation of miRNAs targeting genes required for cell cycle entry. The enhanced Ccnd1 expression may explain the more rapid entry into the S phase of mouse hepatocytes following TCPOBOP

Tracking Acquired Antibiotic Resistance in Commensal Bacteria of GalĂĄpagos Land Iguanas: No Man, No Resistance
BACKGROUND: Antibiotic resistance, evolving and spreading among bacterial pathogens, poses a serious threat to human health. Antibiotic use for clinical, veterinary and agricultural practices provides the major selective pressure for emergence and persistence of acquired resistance determinants. However, resistance has also been found in the absence of antibiotic exposure, such as in bacteria from wildlife, raising a question about the mechanisms of emergence and persistence of resistant strains under similar conditions, and the implications for resistance control strategies. Since previous studies yielded some contrasting results, possibly due to differences in the ecological landscapes of the studied wildlife, we further investigated this issue in wildlife from a remote setting of the Galapagos archipelago. METHODOLOGY/PRINCIPAL FINDINGS: Screening for acquired antibiotic resistance was carried out in commensal enterobacteria from Conolophus pallidus, the terrestrial iguana of Isla Santa Fe, where: i) the abiotic conditions ensure to microbes good survival possibilities in the environment; ii) the animal density and their habits favour microbial circulation between individuals; and iii) there is no history of antibiotic exposure and the impact of humans and introduced animal species is minimal except for restricted areas. Results revealed that acquired antibiotic resistance traits were exceedingly rare among bacteria, occurring only as non-dominant strains from an area of minor human impact. CONCLUSIONS/SIGNIFICANCE: Where both the exposure to antibiotics and the anthropic pressure are minimal, acquired antibiotic resistance traits are not normally found in bacteria from wildlife, even if the ecological landscape is highly favourable to bacterial circulation among animals. Monitoring antibiotic resistance in wildlife from remote areas could also be a useful tool to evaluate the impact of anthropic pressure
