Purpose-This study aims to explore what an authentic approach to engagement with historically underserved and under-resourced communities looks like for social marketers. This helps ensure the voices of the marginalised are heard, and their interests are authentically represented in the development of social marketing interventions. This further reduces risk and unintended negative outcomes from groups engaging in social marketing interventions. Design/methodology/approach-This research follows Podsakoff et al.'s (2016) conceptualisation protocol to answer the research purpose by first identifying the dimensions of authenticity and engagement in social marketing separately, then finding a harmonious link between the core dimensions and thereafter developing and refining a definition. Findings-The research shows that dimensions of authenticity include honesty and transparency, an attitude that is well-meaning, caring, helpful and having a desire for a positive impact, a familiar relationship between social marketers and priority communities, congruous heritage and reputation of change providers with supporting community welfare, effective intervention development and implementation and genuine representation. Moreover, the key dimensions of engagement in social marketing include interacting with or participating in the intervention, building relationships with stakeholders, interaction between social marketers, priority audiences and stakeholders and co-creation between social marketers, priority audiences and other stakeholders. Originality/value-The research contributes to social marketing literature by defining authentic engagement with historically underserved and under-resourced communities. Additionally, as authentic engagement requires considerable collaboration and participation, this research responds to a recent call for more participatory approaches in social marketing. Also, the other contribution includes the key factors needed to operationalise this concept. Accepted
The contributions of potential drivers of uplift and erosion in subduction zone forearcs over geologic time remain unknown. Proposed drivers include coseismic and interseismic earthquake cycle deformation associated with upper-plate forearc faults and the underlying subduction interface. The Hikurangi subduction zone (HSZ), along the eastern North Island of Aotearoa New Zealand, provides a unique location to examine these controls, given both along-strike variations in subduction zone coupling, as well a record of vertical motion from modern and prehistoric earthquakes on forearc faults and the plate interface. There, the Palliser-Kidnappers coastline (PKC) obliquely parallels the plate boundary in proximity to a number of forearc faults and spans a transitional boundary between currently locked and freely slipping portions of the subduction interface. Using digital topographic analysis and catchment-averaged erosion rates from cosmogenic Be-10, we examined the geomorphology of the HSZ forearc to evaluate connections between plate coupling and forearc erosion and uplift. In general, we find overall low concentrations of Be-10 and consequently high rates of erosion that mimic coastal uplift along the PKC, with high rates (>1 mm year(-1)) of erosion concentrated in the south near Cape Palliser. There, the southern Aorangi Range exposes deeper basement terrane rocks that are incised by the steepest fluvial drainages along the PKC, with positive correlation between normalised channel steepness (k(sn)), erosion rate and Late Pleistocene-Holocene uplift rates from marine terraces. Our findings indicate the highest forearc uplift rates occur above the narrow, locked portion of the HSZ, in an area near offshore oblique contractional deformation on the Palliser-Kaiwhata fault.
: With increasing political polarization accompanied by various economic threats and crises, the interplay of politics and work is crucial to understanding emerging phenomena. With this position paper, we highlight what work and organizational psychology can offer in the work-politics nexus. We classify three broad streams in which we see the need for more research on the work-politics nexus: (a) politics affecting work, (b) work affecting political attitudes and engagement, and (c) political participation at work. Using these areas, we highlight the urgency for organizations and practitioners to pay attention and provide future research directions for work and organizational psychology scholars. This position paper aims to highlight initial work and organizational psychological research in the work-politics nexus and encourages work and organizational psychologists to direct more attention toward the intersection of work and the broader civic sphere. Zusammenfassung: Angesichts der zunehmenden politischen Polarisierung, begleitet von verschiedenen wirtschaftlichen Bedrohungen und Krisen, ist das Zusammenspiel von Politik und Arbeit entscheidend f & uuml;r das Verst & auml;ndnis neu auftretender Ph & auml;nomene. Mit diesem Positionspapier heben wir hervor, was die Arbeits- und Organisationspsychologie im Zusammenhang zwischen Arbeit und Politik leisten kann. Wir unterscheiden drei gro ss e Bereiche, in denen wir einen Forschungsbedarf zum Zusammenhang zwischen Arbeit und Politik sehen: (a) Politik, die sich auf die Arbeit auswirkt, (b) Arbeit, die sich auf die Politik auswirkt, und (c) politische Partizipation am Arbeitsplatz. Anhand dieser Bereiche betonen wir die Dringlichkeit f & uuml;r Organisationen, diesem Thema Aufmerksamkeit zu schenken, und geben zuk & uuml;nftige Forschungsrichtungen f & uuml;r Wissenschaftler und Wissenschaftlerinnen der Arbeits- und Organisationspsychologie vor. Dieses Positionspapier soll erste arbeits- und organisationspsychologische Forschungsarbeiten im Zusammenhang zwischen Arbeit und Politik hervorheben und Arbeits- und Organisationspsychologen und -psychologinnen dazu ermutigen, mehr Aufmerksamkeit auf die Schnittstelle zwischen Arbeit und dem breiteren zivilgesellschaftlichen Bereich zu richten.
Although reduced ejection fraction (EF, normal range: 50%-70%) is a hallmark of systolic heart failure, the pathogenesis underlying impaired systolic function remains unclear, and the hemodynamics may play an important role in the process. Here, we present a two-way coupled three-dimensional fluid-structure interaction (FSI) study to compare hemodynamic and biomechanical behavior in a left heart (LH) model with two pathological EF values: severely impaired (24%) and moderately impaired (40%). FSI of the mitral valve (MV) and the aortic valve (AV) has been included. The hemodynamic outputs, detailed flow field, valvular dynamics, and the energy balance are discussed. The results show coordinated opening and closing of the valves and corresponding pressure rise and fall in the ventricle. Comparison of the two EF cases reveals that EF = 40% improves the performance of the MV, achieving a significantly higher inflow velocity and a larger geometric orifice area (GOA) while maintaining the GOA of the AV. Both cases show a competent closure of the AV with negligible regurgitation. The opening of the diastolic MV initiates a bifurcated jet that transitions to a central high-speed stream, generating left ventricle (LV) vortices that mitigate the risk of stasis, a mechanism that is attenuated at EF = 24%. Energy analysis shows EF = 40% requires a greater input of LV work, coupled with an elevated power and kinetic energy flux at the aortic outlet, and dissipation within LH. These findings may help elucidate the EF-dependent hemodynamic coupling underlying pathological and compensatory cardiac functions and may provide a framework for future study of a pathological feedback loop linking valvular function, ventricular filling, and cardiac output.
Understanding plant competitive outcomes, driven by niche and fitness differences, requires exploring these differences across simultaneous changes in abiotic and biotic conditions, such as soil properties, mutualisms and natural enemies. Here, we combined coexistence theory with detailed field observations in an annual grassland over two consecutive years and in silico simulations to assess changes in competitive outcomes, from coexistence to competitive exclusion, and from exclusion to priority effects. Our analysis shows that competitive exclusion is the most common outcome but with marked changes in the identity of the superior competitor under abiotic and biotic variation, highlighting the potential for regional coexistence. Herbivores were identified as the factor with the largest effect on the sensitivity of species pairs to shifts between coexistence and exclusion, although the effect size reflects sensitivity rather than the direction of change. Additionally, herbivores strongly influence the identity of the superior competitor, which can promote coexistence at larger spatial scales. Local coexistence was rarely predicted in our system. Finally, priority effects were mostly observed in the absence of a deterministic driver, as expected. Overall, our results suggest that while local coexistence is limited, species diversity can be maintained across larger spatial scales through shifts in competitive dominance mediated by multiple abiotic and biotic drivers.
