Evolving conceptions of work-family boundaries: In defense of the family as stakeholder

In the management and organization studies literature, a key question to explore and explain is that of the family as an organizational stakeholder, particularly when working-from-home became the “new normal”. Departing from meta-analytic studies on the work-family relation and connecting with scholarly conversation on work-family boundary dynamics, we identify three main narratives. In the separation narrative, work and family belong to different realms, and including the family in the domain of organizational responsibility is seen as pointless. The interdependence narrative stresses that organizations and families are overlapping domains in which it is important to acknowledge that the policies and practices of the former might have an impact on family life, and vice-versa. The embeddedness narrative, brought to the fore by the COVID-19 pandemic, sees employment and family as progressively convergent and hybrid work domains. The evolution of employment relations towards increased hybridity of the work situation being embedded in the familial/household context increasingly calls for consideration of the family/household as an integral rather than a peripheral stakeholder.info:eu-repo/semantics/publishedVersio

Efeito do manejo de rebrotas de espécies lenhosas da caatinga sobre o crescimento em altura das hastes.

Resumo: O experimento foi conduzido para avaliar o efeito do manejo de rebrotas de cinco espécies lenhosas da caatinga sobre o crescimento em altura das hastes. As espécies lenhosas foram submetidas aos seguintes tratamentos no delineamento inteiramente casualizado: 1 - preservação de uma haste; 2 - preservação de duas hastes; 3 - preservação de três hastes; 4 - preservação de todas as hastes. As plantas submetidas ao manejo de preservação de uma haste apresentaram maior crescimento de haste e o menor crescimento de haste foi observado para plantas submetidas ao tratamento de preservação de todas as hastes. Dentre as espécies lenhosas estudadas, a jurema preta (Mimosa hostilis) apresentou maior crescimento das hastes e a catingueira (Caesalpinia bracteosa), o menor crescimento de hastes sendo recomendada a sua preservação e uso como recurso forrageiro. A preservação de uma haste por planta propicia o maior crescimento em altura de hastes de espécies lenhosas da caatinga e, a exceção da catingueira, as demais espécies apresentam potencial para produção simultânea de lenha e forragem. [Effect of the management of the sprouts of the tree species of caating on the growth in the height of the stems]. Abstract - The experiment was carried to evaluate the effect of the management of sprouts of five woody species of caatinga on the growth in height of the stems. The woody species were assigned to a completely randomized design to the following treatments: 1-preservation of one stem; 2-preservation of two stems; 3-preservation of three stems; 4-preservation of all of the stems. Plants submitted to the management of preservation of one stem presented larger stem growth and the smallest stem growth was observed for plants submitted to the treatment of preservation of all of the stems. Among the studied woody species, the Mimosa hostilis presented larger growth of the stems and Caesalpinia bracteosa, the smallest growth of stems being recommended to preservation and use as resource forage. The preservation of one stem for plant propitiates the largest growth in height of stems of woody species of caatinga and, the exception of the Caesalpinia bracteosa, the other species present potential for simultaneous production of firewood and forage

Influence of a Physiologically Formed Blood Clot on Pre-Osteoblastic Cells Grown on a BMP-7-Coated Nanoporous Titanium Surface

Titanium (Ti) nanotopography modulates the osteogenic response to exogenous bone morphogenetic protein 7 (BMP-7) in vitro, supporting enhanced alkaline phosphatase mRNA expression and activity, as well as higher osteopontin (OPN) mRNA and protein levels. As the biological effects of OPN protein are modulated by its proteolytic cleavage by serum proteases, this in vitro study evaluated the effects on osteogenic cells in the presence of a physiological blood clot previously formed on a BMP-7-coated nanostructured Ti surface obtained by chemical etching (Nano-Ti). Pre-osteoblastic MC3T3-E1 cells were cultured during 5 days on recombinant mouse (rm) BMP-7-coated Nano-Ti after it was implanted in adult female C57BI/6 mouse dorsal dermal tissue for 18 h. Nano-Ti without blood clot or with blood clot at time 0 were used as the controls. The presence of blood clots tended to inhibit the expression of key osteoblast markers, except for Opn, and rmBMP-7 functionalization resulted in a tendency towards relatively greater osteoblastic differentiation, which was corroborated by runt-related transcription factor 2 (RUNX2) amounts. Undetectable levels of OPN and phosphorylated suppressor of mothers against decapentaplegic (SMAD) 1/5/9 were noted in these groups, and the cleaved form of OPN was only detected in the blood clot immediately prior to cell plating. In conclusion, the strategy to mimic in vitro the initial interfacial in vivo events by forming a blood clot on a Ti nanoporous surface resulted in the inhibition of pre-osteoblastic differentiation, which was minimally reverted with an rmBMP-7 coating

Generalized Heisenberg Algebras and Fibonacci Series

We have constructed a Heisenberg-type algebra generated by the Hamiltonian, the step operators and an auxiliar operator. This algebra describes quantum systems having eigenvalues of the Hamiltonian depending on the eigenvalues of the two previous levels. This happens, for example, for systems having the energy spectrum given by Fibonacci sequence. Moreover, the algebraic structure depends on two functions f(x) and g(x). When these two functions are linear we classify, analysing the stability of the fixed points of the functions, the possible representations for this algebra.Comment: 24 pages, 2 figures, subfigure.st
