This study investigates the relationship of University Social Responsibility (USR) initiatives, its social media communication and faculty satisfaction. The increasing importance of USR for ...stakeholders is reflected in relevant rankings, accreditation institutions, and the expectations of faculty and students. However, most researchers have ignored this topic. This study adopted social identity theory to explore the effects of USR on faculty satisfaction. We surveyed 107 academics from top 50 business schools listed in the Financial Times. Our survey was based on the Collaborative on Academic Careers in Higher Education (COACHE) scale and a pre-established USR scale. Using the PLS-SEM analysis, we found that the relationship between USR communication and the general satisfaction of faculty is mediated through the faculty's satisfaction with university management.
•The effect xenobiotics (DDT, DDE, aldrine and dieldrine) on the secretory activity of smooth chorion slices was tested.•The synthesis and release of prostaglandin F2α, E2, oxytocin, progesterone, ...and estradiol and was studied.•The expression of enzymes participate in synthesis of these hormones was determined.•Used xenobiotics unfavorably affect the releasing studied hormones from smooth chorion.
Chlorooganic xenobiotics (XBs) such as DDT, DDE, aldrin and dieldrin interfere with release of hormones from chorionic villi that are necessary for sustaining the normal course pregnancy: prostaglandins (PGs), oxytocin (OT), progesterone (P4) and estradiol (E2). Approximately 20 %–40 % of these hormones originate from the smooth chorion. The aim of current studies was to investigate effects of these XBs on synthesis and release of PGE2, PGF2α, OT, P4 and E2 from explants of smooth chorion of cattle, obtained during the120–150 and 151–180 day gestational period. Explants were incubated with DDT, DDE, aldrin or dieldrin at concentrations of 1 and 10 ng/mL for 24 h, and concentrations of PGE2, PGF2α, OT, P4 and E2 in post incubation medium and the relative abundances of COX-2, PTGES, AKR1B1, NP-I/OT, PAM, HSD3B, and CYP19A1 mRNA transcripts in tissue explants were determined. The XBs did not have effects on cell viability in explants (P > 0.05), however, there were effects on prostaglandins, OT and P4 secretion and relative abundance of mRNA transcript for genes encoding the main enzymes involved in synthesis of these hormones (P < 0.05). The XBs that were evaluated did not have effects on E2 synthesis and secretion (P > 0.05). In summary, XBs evaluated in the present study had effects on the pattern of prostaglandin secretion, and can increase OT and P4 release from smooth chorion explants. Because XBs inhibit hormonal action throughout the chorion, there is an increase in risk of abortions or premature births in animals.
There are a number of conceptual models of dementia, capturing a range of biopsychosocial factors. Few integrate the lived experience of dementia. The aim of this study was to develop a ...conceptualisation grounded in the first-hand accounts of living with the condition and reflecting its complexity.
The study was conducted within an explanatory, critical realist paradigm. An overarching narrative approach, informed by a previously completed systematic review and metasynthesis of research on the lived experience of dementia and the assumptions of complexity theory, was used to guide data collection and analysis. Data were contributed by 31 adults, including 12 people living with dementia and 19 family caregivers.
The experience of living with dementia was conceptualised as a process of adaptation through participation, emerging from ongoing, dynamic and nonlinear interactions between the adaptive capacity of a person with dementia and the adaptive capacity within the environment. The proposed conceptual model describes contexts and mechanisms which shape this capacity. It identifies a range of potential outcomes in dementia. These outcomes reflect interactions and the degree of match between the adaptive capacity of a person and the adaptive capacity within the environment.
By recognising and exploring the potential for adaptation and enduring participation in dementia, findings of this research can support practitioners in facilitating positive outcomes for people affected by the condition.

Abstract
Compared with the ancestral C3 state, C4 photosynthesis occurs at higher rates with improved water and nitrogen use efficiencies. In both C3 and C4 plants, rates of photosynthesis increase ...with light intensity and are maximal around midday. We determined that in the absence of light or temperature fluctuations, photosynthesis in maize (Zea mays) peaks in the middle of the subjective photoperiod. To investigate the molecular processes associated with these temporal changes, we performed RNA sequencing of maize mesophyll and bundle sheath strands over a 24-h time course. Preferential expression of C4 cycle genes in these cell types was strongest between 6 and 10 h after dawn when rates of photosynthesis were highest. For the bundle sheath, DNA motif enrichment and gene coexpression analyses suggested members of the DNA binding with one finger (DOF) and MADS (MINICHROMOSOME MAINTENANCE FACTOR 1/AGAMOUS/DEFICIENS/Serum Response Factor)-domain transcription factor families mediate diurnal fluctuations in C4 gene expression, while trans-activation assays in planta confirmed their ability to activate promoter fragments from bundle sheath expressed genes. The work thus identifies transcriptional regulators and peaks in cell-specific C4 gene expression coincident with maximum rates of photosynthesis in the maize leaf at midday.
The spatial partitioning of C4 gene expression between mesophyll and bundle sheath strands is dependent on time of day.
Purpose: This study aims to empirically present the process of personal branding of CEOs. Building on the theoretical model proposed by Wojtaszczyk and Maszewski (2014), the study illustrates how ...CEOs build their personal brands. Methodology: The study is based on twelve semi-structured interviews with the CEOs of Poland’s strongest brands. Results were coded and analyzed with the use of MAXQDA software. Results: The research allowed us to understand the process of creating a personal brand by CEOs. Moreover, interviews revealed that the personal brand reflects the true self of CEOs. However, it is also adjusted to the target audience; consequently, CEOs show diverse identities to the outside world. Implications: Through the empirical investigation of the branding process, the findings fill a certain research gap. Insights gained in the process may prove useful for practitioners. Originality/value: The article explores the subject of the personal brand, which continues to be the focus of many researchers, particularly in the CEE region. This research gave voice to CEOs, who explained how they build their personal brand and shared detailed information whose scope greatly exceeds what they present in the media.
A new maternity colony of lesser horseshoe bats (Rhinolophus hipposideros) was found and described in an abandoned building in Aljezur, Portugal. Between June 25 and July 4, 2022, we conducted ...emergence and juvenile counts, took light intensity measurements during emergence times and evaluated microclimatic conditions inside the roost, namely temperature and relative humidity. Moreover, we took ultrasound recordings in the open and performed transects to locate foraging areas and commuting corridors. We found the colony amounted to at least 501 individuals (371 adults and 130 juveniles), currently the largest known in Portugal and one of the biggest in Europe. Sixteen matching echolocation calls were recorded away from the colony near a water reservoir, a probable foraging area together with the Vale da Telha valley connecting the roost to the water body, which may also serve as a commuting corridor. Considering the threatened conservation status of the lesser horseshoe bat, the large colony size and its lack of protection, we proposed several conservation measures aimed at preserving the colony. We hope our recommendations will be included in the management plan currently being prepared for the Natura 2000 site Costa Sudoeste. Following up on this research, a radio-tracking study would definitively confirm the bats’ movements and foraging grounds.

The Monte-Carlo simulated response for γ-ray detection of the FAst TIMing Array (FATIMA) for exploitation within the DEcay SPECtroscopy (DESPEC) experimental system at the FAIR Phase-0 facility at ...Darmstadt, Germany is presented. In this configuration, FATIMA consisted of 36 LaBr3(Ce) detectors surrounding the AIDA, position-sensitive charged-particle active stopper. The decay of the Iπ=8+ isomer-fed decay cascade in 96Pd, measured in the first DESPEC experiment at the FAIR-0 facility was used to validate the simulations. The experimental data yielded in-situ full-energy peak efficiency values for FATIMA of 11.2(11)%, 6.8(7)%, 3.8(4)% and 2.1(4)% at 106, 325, 684 and 1415 keV respectively, consistent with the values derived from the simulated response.
This work aims at presenting an alternative approach to the long standing problem of the B(E2) values in Sn isotopes in the vicinity of the N=Z double-magic nucleus 100Sn, until now predominantly ...measured with relativistic and intermediate-energy Coulomb excitation reactions. The direct measurement of the lifetime of low-lying excited states in odd-even Sn isotopes provides a new and precise guidance for the theoretical description of the nuclear structure in this region. Lifetime measurements have been performed in 105Sn for the first time with the coincidence Recoil Distance Doppler Shift technique. The lifetime results for the 7/21+ first excited state and the 11/21+ state, 2+(104Sn) ⊗ν1g7/2 multiplet member, are discussed in comparison with state-of-the-art shell model and mean field calculations, highlighting the crucial contribution of proton excitation across the core of 100Sn. The reduced transition probability B(E2) of the 11/21+ core-coupled state points out an enhanced staggering with respect to the B(E2; 21+→01+) in the even-mass 104Sn and 106Sn isotopes.
The shell structure of atomic nuclei is associated with 'magic numbers' and originates in the nearly independent motion of neutrons and protons in a mean potential generated by all nucleons. During ...β(+)-decay, a proton transforms into a neutron in a previously not fully occupied orbital, emitting a positron-neutrino pair with either parallel or antiparallel spins, in a Gamow-Teller or Fermi transition, respectively. The transition probability, or strength, of a Gamow-Teller transition depends sensitively on the underlying shell structure and is usually distributed among many states in the neighbouring nucleus. Here we report measurements of the half-life and decay energy for the decay of (100)Sn, the heaviest doubly magic nucleus with equal numbers of protons and neutrons. In the β-decay of (100)Sn, a large fraction of the strength is observable because of the large decay energy. We determine the largest Gamow-Teller strength so far measured in allowed nuclear β-decay, establishing the 'superallowed' nature of this Gamow-Teller transition. The large strength and the low-energy states in the daughter nucleus, (100)In, are well reproduced by modern, large-scale shell model calculations.
