\"Public trust in business is one of the most important but least understood issues for business leaders, public officials, employees, NGOs and other key stakeholders. This book provides much-needed thinking on the topic. Drawing on the expertise of an international array of experts from academic disciplines including business, sociology, political science and philosophy, it explores long-term strategies for building and maintaining public trust in business. The authors look to new ways of moving forward by carefully blending the latest academic research with conclusions for future research and practice. They address core drivers of public trust, how to manage it effectively, the consequences of low public trust, and how best to trust challenges and restore trust when it has been lost. This is a must-read for business practitioners, policy makers and students taking courses in corporate social responsibility or business ethics\"-- Provided by publisher.

Understanding magma fragmentation mechanisms in explosive eruptions is a key requirement for volcanic hazard assessment, eruption management and risk mitigation. This paper focuses on a type case small explosivity eruption (July–August 2015 eruption of Piton de la Fournaise). These eruptions, despite being often overlooked, are exceedingly frequent on local-to-global scales and constitute a significant hazard in vent-proximal areas, which are often populated by guides, tourists and, indeed, volcanologists due to their accessibility. The explosions presented here are ideal cases for the study of the dynamics of magma fragmentation and how it relates to the size distribution of scoria generated at the vent. We documented these events visually and thermally, and characterised the products through sample-return. This allowed us to describe small-scale gas bursts sending ejecta up to 30 m during intermittent lava fountains. Surface tension instabilities and inertial forces played a major role in fragmentation processes and generated particles with coarse-skewed distributions and median diameters ranging from − 8 to − 10 ϕ. However, with time distributions of particles in the most energetic fountains shifted towards more symmetrical shapes as median grains sizes became finer. Analyses of sequences of images demonstrate that the evolution of particle size distributions with time is due to instability of magma droplets and (in-flight) fragmentation.

Gentrification has become a global phenomenon over the past 15 years and has been understood as an increasingly important strategy within neo-liberal policy-making. Focusing on London and Mumbai, this paper details how public policies and planning regimes have been reconfigured and rescaled to facilitate and encourage new property speculation. However, against more generalised and abstract accounts of the neo-liberal city, the paper uses its comparative perspective to emphasise the geographically and historically specific manifestations and effects of gentrification processes. By highlighting different forms of state intervention and sharper socio-spatial impacts in Mumbai, the paper challenges the Eurocentric framing of a global spread of gentrification and argues that Mumbai can act as an important source of learning for gentrification research.

Piton de la Fournaise, situated on La Réunion island (France), is one of the most active hot spot basaltic shield volcanoes worldwide, experiencing at least two eruptions per year since the establishment of the volcanological observatory in 1979. Eruptions are typically fissure-fed and form extensive lava flow fields. About 95 % of some ∼ 250 historical events (since the first confidently dated eruption in 1708) have occurred inside an uninhabited horseshoe-shaped caldera (hereafter referred to as the Enclos), which is open to the ocean on its eastern side. Rarely (12 times since the 18th century), fissures have opened outside of the Enclos, where housing units, population centers, and infrastructure are at risk. In such a situation, lava flow hazard maps are a useful way of visualizing lava flow inundation probabilities over large areas. Here, we present the up-to-date lava flow hazard map for Piton de la Fournaise based on (i) vent distribution, (ii) lava flow recurrence times, (iii) statistics of lava flow lengths, and (iv) simulations of lava flow paths using the DOWNFLOW stochastic numerical model. The map of the entire volcano highlights the spatial distribution probability of future lava flow invasion for the medium to long term (years to decades). It shows that the most probable location for future lava flow is within the Enclos (where there are areas with up to 12 % probability), a location visited by more than 100 000 visitors every year. Outside of the Enclos, probabilities reach 0.5 % along the active rift zones. Although lava flow hazard occurrence in inhabited areas is deemed to be very low (< 0.1 %), it may be underestimated as our study is only based on post-18th century records and neglects older events. We also provide a series of lava flow hazard maps inside the Enclos, computed on a multi-temporal (i.e., regularly updated) topography. Although hazard distribution remains broadly the same over time, some changes are noticed throughout the analyzed periods due to improved digital elevation model (DEM) resolution, the high frequency of eruptions that constantly modifies the topography, and the lava flow dimensional characteristics and paths. The lava flow hazard map for Piton de la Fournaise presented here is reliable and trustworthy for long-term hazard assessment and land use planning and management. Specific hazard maps for short-term hazard assessment (e.g., for responding to volcanic crises) or considering the cycles of activity at the volcano and different event scenarios (i.e., events fed by different combinations of temporally evolving superficial and deep sources) are required for further assessment of affected areas in the future – especially by atypical but potentially extremely hazardous large-volume eruptions. At such an active site, our method supports the need for regular updates of DEMs and associated lava flow hazard maps if we are to be effective in keeping up to date with mitigation of the associated risks.

At hydrothermal systems, heat transfer across the final surface layer is driven by permeable convection and conduction, so that soil permeability and thermal conductivity play fundamental roles in controlling heat flux to the atmosphere. We build a Rayleigh-number driven heat transfer model for a bottom-heated surface that uses measurements of heat flux density (radiation and convection to the atmosphere in W/m 2 ), surface temperature, and soil temperature to solve for soil conductivity, density, and permeability for such a bottom-heated surface. At Vulcano in 2019, we measured an ASTER-derived heat flux density of 240 ± 70 W/m 2 and a difference between soil and surface temperature of 18 ± 6 °C. The surface layer is a 7.5 ± 2.5 cm thick case-hardened crust across which heat transfer is conduction dominated. We invert our heat transfer model using the temperature (T) gradient derived from a trench dug into the soil: T  =  − 49.7y 2  + 113.6y + 35 ( R 2  = 0.9997), where y is depth in meters between the surface and 70 cm. The result is a conductivity for the case-hardened surface layer of 1.0 ± 0.3 W/(m K) and a density of 2440 ± 120 kg/m 3 . Below this case-hardened crust, heat transfer is dominated by permeable convection in a soil comprised of highly altered trachytic blocks in an ash matrix. Our model gives permeabilities of 1–19 × 10 −10 m 2 for this layer in 2019. In 2021, Vulcano entered a phase of unrest. Our model reveals that this was associated with an increase in permeability to 10 −7 m 2 . However, by 2023 permeabilities had reverted to pre-unrest levels. Using simple measurements of surface and soil temperature, coupled with heat flux density from a satellite overpass, the model can be used as a basis to constrain heat transfer and to assess permeability at any hydrothermal system.

السعي وراء ما يبنغي للناس عمله في شركاتهم إن أول سؤال قد يخطر ببال المستثمر هو كيف أتميز ؟ وأول عمل يسعى له هو التميز. ولا شك أن الشركات المميزة خططها مميزة وطاقمها مميز وقادرة على المواكبة والناعمة ولكن الحظ السئ يكون عند الشركات الناشئة، فعلى اجتهادهم لتكون أعمالهم في أكمل صورة وأحسن جودة، إلا أنهم يرون عملهم قد أصبح فوضى عارمة، مع أنهم يضعون الأساس ويرسمون الصور وينفذون الخطط، وحينما يبحثون عن أسرع حل لترتيب هذه الفوضى، يزيد عليهم الطين بلة، فما هي أسباب هذا الإخفاق؟ وما الذي قد يساعدهم لتجنب ذلك؟ ‪‪‪‪‪‪‪‪‪‪
