‘It's the organization that is wrong’:Exploring disengagement from organizations through leadership development

This research explores the relationship between participation in leadership development programmes and disengagement from the employing organization. Based on repeated interviews with 10 managers participating in an open leadership development programme, our analysis shows that half of the participants reflected a sense of distancing themselves from how their organizations practiced leadership, and for some, an emotional disengagement with their home organization which we see as analogous to changes in social identity. We problematize the role of management and leadership development programmes with regard to the relationship between organizations and employees. A series of paradoxes are reflected in our critique of this relationship. The most prominent in terms of implications is that a successful management and leadership development programme – recognized by employees and employers – can generate dissatisfaction with the home organization as a consequence of the purpose of the programme: to increase confidence and enhanced agency. This paradox has significant implication to the leadership development industry and we explore these implications

Galaxy and Mass Assembly (GAMA): merging galaxies and their properties

We derive the close pair fractions and volume merger rates for galaxies in the Galaxy and Mass Assembly (GAMA) survey with −23 < Mr < −17 (ΩM = 0.27, ΩΛ = 0.73, H0 = 100 km s−1 Mpc−1) at 0.01 < z < 0.22 (look-back time of <2 Gyr). The merger fraction is approximately 1.5 per cent Gyr−1 at all luminosities (assuming 50 per cent of pairs merge) and the volume merger rate is ≈3.5 × 10−4 Mpc−3 Gyr−1. We examine how the merger rate varies by luminosity and morphology. Dry mergers (between red/spheroidal galaxies) are found to be uncommon and to decrease with decreasing luminosity. Fainter mergers are wet, between blue/discy galaxies. Damp mergers (one of each type) follow the average of dry and wet mergers. In the brighter luminosity bin (−23 < Mr < −20), the merger rate evolution is flat, irrespective of colour or morphology, out to z ∼ 0.2. The makeup of the merging population does not appear to change over this redshift range. Galaxy growth by major mergers appears comparatively unimportant and dry mergers are unlikely to be significant in the buildup of the red sequence over the past 2 Gyr. We compare the colour, morphology, environmental density and degree of activity (BPT class, Baldwin, Phillips & Terlevich) of galaxies in pairs to those of more isolated objects in the same volume. Galaxies in close pairs tend to be both redder and slightly more spheroid dominated than the comparison sample. We suggest that this may be due to ‘harassment’ in multiple previous passes prior to the current close interaction. Galaxy pairs do not appear to prefer significantly denser environments. There is no evidence of an enhancement in the AGN fraction in pairs, compared to other galaxies in the same volume

Online and print newspapers in Europe in 2003. Evolving towards complementarity

This article assesses online newspapers in Europe from a media evolutionary perspective, ten years after the introduction of the World Wide Web. Comparing print and online front pages of 51 newspapers in 14 countries in 2003, we argue that online newspapers complement print newspapers in modest ways. Online, publishers put more emphasis on service information, offer additional news items, that nonetheless report on similar topics in similar ways, and add personal interactivity, content selectivity and realtime news to the print news offering. One subset of online newspapers charges for services, and offers more content and personal interactivity. Another, partly overlapping subset offers more original news; in a short and anonymous format. Overall, however, online newspapers in Europe make up a heterogeneous group, suggesting that online newspapers still have to find their definite form and role in the European news market

A systematic review of randomised controlled trials of radiotherapy for localised prostate cancer

Background: Prostate cancer is the second most frequently diagnosed cancer and the sixth leading cause of cancer death in males. A systematic review of randomised controlled trials (RCTs) of radiotherapy and other non-pharmacological management options for localised prostate cancer was undertaken. Methods: A search of thirteen databases was carried out until March 2014.RCTs comparing radiotherapy (brachytherapy (BT) or external beam radiotherapy (EBRT)) to other management options i.e. radical prostatectomy (RP), active surveillance, watchful waiting, high intensity focused ultrasound (HIFU), or cryotherapy; each alone or in combination, e.g. with adjuvant hormone therapy (HT), were included. Methods followed guidance by the Centre for Reviews and Dissemination and the Cochrane Collaboration. Indirect comparisons were calculated using the Butcher method. Results: Thirty-six randomised controlled trials (RCTs, 134 references) were included. EBRT, BT and RP were found to be effective in the management of localised prostate cancer. While higher doses of EBRT seem to be related to favourable survival-related outcomes they might, depending on technique, involve more adverse events, e.g. gastrointestinal and genitourinary toxicity. Combining EBRT with hormone therapy shows a statistically significant advantage regarding overall survival when compared to EBRT alone (Relative risk 1.21, 95% confidence interval 1.12-1.30). Aside from mixed findings regarding urinary function, BT and radical prostatectomy were comparable in terms of quality of life and biochemical progression-free survival while favouring BT regarding patient satisfaction and sexual function. There might be advantages of EBRT (with/without HT) compared to cryoablation (with/without HT). No studies on HIFU were identified. Conclusions: Based on this systematic review, there is no strong evidence to support one therapy over another as EBRT, BT and RP can all be considered as effective mono therapies for localised disease with EBRT also effective for post-operative management. All treatments have unique adverse events profiles. Further large, robust RCTs which report treatment-specific and treatment combination-specific outcomes in defined prostate cancer risk groups following established reporting standards are needed. These will strengthen the evidence base for newer technologies, help reinforce current consensus guidelines and establish greater standardisation across practices

Undersea Constellations: The Global Biology of an Endangered Marine Megavertebrate Further Informed through Citizen Science

The whale shark is an ideal flagship species for citizen science projects because of its charismatic nature, its size, and the associated ecotourism ventures focusing on the species at numerous coastal aggregation sites. An online database of whale shark encounters, identifying individuals on the basis of their unique skin patterning, captured almost 30,000 whale shark encounter reports from 1992 to 2014, with more than 6000 individuals identified from 54 countries. During this time, the number of known whale shark aggregation sites (hotspots) increased from 13 to 20. Examination of photo-identification data at a global scale revealed a skewed sex-ratio bias toward males (overall, more than 66%) and high site fidelity among individuals, with limited movements of sharks between neighboring countries but no records confirming large, ocean basin-scale migrations. Citizen science has been vital in amassing large spatial and temporal data sets to elucidate key aspects of whale shark life history and demographics and will continue to provide substantial long-term value

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Measurements of the Electroweak Diboson Production Cross Sections in Proton-Proton Collisions at root s=5.02 TeV Using Leptonic Decays

The first measurements of diboson production cross sections in proton-proton interactions at a center-of-mass energy of 5.02 TeV are reported. They are based on data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 302 pb(-1). Events with two, three, or four charged light leptons (electrons or muons) in the final state are analyzed. The WW, WZ, and ZZ total cross sections are measured as sigma(WW) = 37:0(-5.2)(+5.5) (stat)(-2.6)(+2.7) (syst) pb, sigma(WZ) = 6.4(-2.1)(+2.5) (stat)(-0.3)(+0.5)(syst) pb, and sigma(ZZ) = 5.3(-2.1)(+2.5)(stat)(-0.4)(+0.5) (syst) pb. All measurements are in good agreement with theoretical calculations at combined next-to-next-to-leading order quantum chromodynamics and next-to-leading order electroweak accuracy
