Leadership and succession in Trinidadian family businesses

This research examines the qualities required for establishing effective leadership succession in private Family Businesses (pFB) in Trinidad, private meaning those still wholly-owned by family members. Trinidad’s pFB are major employers and contributors to economies globally and, yet, prior research shows that only around a quarter to a third survive to a second generation and only one-in-ten to a third. Therefore, identifying and developing the factors that support pFB continuity and transition are important both locally and internationally. This study identifies the key leadership and related elements for successful pFB continuity and succession in the Caribbean nation of Trinidad. The research is based on a qualitative approach, using in-depth, semi-structured, and open-ended interviews with eleven purposively-selected local pFB leaders. Interviewees comprised first- and second-generation leaders with ten existing pFB’s and one now-dormant pFB. The results show that none had established formal succession plans, but achieved success principally through effective face-to-face conversations between the leader, typically the parent, and the successor, typically one of the parents’ children. The research provides a valuable insight into the critical qualities deemed necessary for leaders to achieve continuity in their family business. The eight qualities identified for pFB success emanated from the data gathered (capability; honesty; and integrity), from the conceptual framework developed based on prior literature (vision; and effective communication), and from the discussions held (industry knowledge; a sound knowledge of the pFB organisational structures; and the support of the incumbent leader). These, alongside some measures of financial performance, lead to long-term success, and therefore generational continuity. This research extends current knowledge on how pFB continuity in Trinidad may be achieved, based on identifying the leadership qualities required. Further research is recommended on refining such knowledge across the Caribbean and into different territories, sectors, markets and industries

Validity of the CMSSM interpretation of the diphoton excess

It has been proposed that the observed diphoton excess at 750 GeV could be explained within the constrained minimal supersymmetric standard model via resonantly produced stop bound states. We reanalyze this scenario critically and extend previous work to include the constraints from the stability of the electroweak vacuum and from the decays of the stoponium into a pair of Higgs bosons. It is shown that the interesting regions of parameter space with a light stop and Higgs of the desired mass are ruled out by these constraints. This conclusion is not affected by the presence of the bound states because the binding energy is usually very small in the regions of parameter space which can explain the Higgs mass. Thus, this also leads to strong constraints on the diphoton production cross section which is in general too small.Comment: 8 pages, 5 figures; v2: added Fig. 5, matches published versio

Particles of Moisture or other Substance Suspended in Air and Visible as Clouds: Complexity in Site-Related Creative Practices

Outlining a history, theory and practice of site-related creative practices across poetry, art and architecture, this book chapter works to contextualise the practice-based research of the creative collaborative pair Kreider + O’Leary. Alongside this written component, Kreider + O’Leary engage with an expanded drawing technique to delineate the specific narrative of one of their site-related projects

Homelessness and the Private Rented Sector

Homelessness has a devastating effect on those who experience it and is costly to the public purse. Homelessness acceptances have been increasing since 2009, with the most significant growth being from the private rented sector. The number of such households has grown in absolute terms – from 4580 acceptances in 2009 to 16,320 acceptances in 2017, and as a proportion of all acceptances, from eleven percent to twenty eight percent (MHCLG, 2018). Yet, while there has been some excellent research published recently about particular aspects of this growth, there remain a number of gaps in our understanding. Knowing what is driving recent increases in homelessness from the private rented sector is key to understanding what policy and other changes are necessary to address this proble

Leukotrienes provide an NFAT-dependent signal that synergizes with IL-33 to activate ILC2s.

Group 2 innate lymphoid cells (ILC2s) and type 2 helper T cells (Th2 cells) are the primary source of interleukin 5 (IL-5) and IL-13 during type 2 (allergic) inflammation in the lung. In Th2 cells, T cell receptor (TCR) signaling activates the transcription factors nuclear factor of activated T cells (NFAT), nuclear factor κB (NF-κB), and activator protein 1 (AP-1) to induce type 2 cytokines. ILC2s lack a TCR and respond instead to locally produced cytokines such as IL-33. Although IL-33 induces AP-1 and NF-κB, NFAT signaling has not been described in ILC2s. In this study, we report a nonredundant NFAT-dependent role for lipid-derived leukotrienes (LTs) in the activation of lung ILC2s. Using cytokine reporter and LT-deficient mice, we find that complete disruption of LT signaling markedly diminishes ILC2 activation and downstream responses during type 2 inflammation. Type 2 responses are equivalently attenuated in IL-33- and LT-deficient mice, and optimal ILC2 activation reflects potent synergy between these pathways. These findings expand our understanding of ILC2 regulation and may have important implications for the treatment of airways disease

Payment by results and social impact bonds: Outcome-based payment systems in the UK and US

All right reserved. As public services budgets are cut, the 'Payment by Results' (or Pay for Success) model has become a popular choice in public sector commissioning. Social Impact Bonds are a variant of Payment by Results also promoted by proponents of social (or impact) investing. But how effective are these approaches? This short book asks whether the Payment by Results model is an efficient way to unlock new capital investment, help new providers to enter the 'market' and foster innovation, or whether the extension of 'neoliberal' thinking, complexity and the effects of managerialism undermine the effective delivery of social outcomes. Synthesising lessons from the UK and US for the first time, the book draws on published work in both countries together with insights from the authors' own research and consultancy experience to offer a balanced and bipartisan overview of a field where the evidence has been weak and there are strong ideological agendas in play

Non-invasive and non-destructive measurements of confluence in cultured adherent cell lines

Many protocols used for measuring the growth of adherent monolayer cells in vitro are invasive, destructive and do not allow for the continued, undisturbed growth of cells within flasks. Protocols often use indirect methods for measuring proliferation. Microscopy techniques can analyse cell proliferation in a non-invasive or non-destructive manner but often use expensive equipment and software algorithms. In this method images of cells within flasks are captured by photographing under a standard inverted phase contract light microscope using a digital camera with a camera lens adaptor. Images are analysed for confluence using ImageJ freeware resulting in a measure of confluence known as an Area Fraction (AF) output. An example of the AF method in use on OVCAR8 and UPN251 cell lines is included. •Measurements of confluence from growing adherent cell lines in cell culture flasks is obtained in a non-invasive, non-destructive, label-free manner. •The technique is quick, affordable and eliminates sample manipulation. •The technique provides an objective, consistent measure of when cells reach confluence and is highly correlated to manual counting with a haemocytometer. The average correlation co-efficient from a Spearman correlation (n = 3) was 0.99 ± 0.008 for OVCAR8 (p = 0.01) and 0.99 ± 0.01 for UPN251 (p = 0.01) cell lines

Nuclear alpha-clustering, superdeformation, and molecular resonances

Nuclear alpha-clustering has been the subject of intense study since the advent of heavy-ion accelerators. Looking back for more than 40 years we are able today to see the connection between quasimolecular resonances in heavy-ion collisions and extremely deformed states in light nuclei. For example superdeformed bands have been recently discovered in light N=Z nuclei such as $^{36}$Ar, $^{40}$Ca, $^{48}$Cr, and $^{56}$Ni by $\gamma$-ray spectroscopy. The search for strongly deformed shapes in N=Z nuclei is also the domain of charged-particle spectroscopy, and our experimental group at IReS Strasbourg has studied a number of these nuclei with the charged particle multidetector array {\sc Icare} at the {\sc Vivitron} Tandem facility in a systematical manner. Recently the search for $\gamma$-decays in $^{24}$Mg has been undertaken in a range of excitation energies where previously nuclear molecular resonances were found in $^{12}$C+$^{12}$C collisions. The breakup reaction $^{24}$Mg$+^{12}$C has been investigated at E$_{lab}$($^{24}$Mg) = 130 MeV, an energy which corresponds to the appropriate excitation energy in $^{24}$Mg for which the $^{12}$C+$^{12}$C resonance could be related to the breakup resonance. Very exclusive data were collected with the Binary Reaction Spectrometer in coincidence with {\sc Euroball IV} installed at the {\sc Vivitron}.Comment: 10 pages, 4 eps figures included.
