Signaling valuable human capital: Advocacy group work experience and its effect on employee pay in innovative firms

© 2018 John Wiley & Sons, Ltd. Research Summary: The ability of innovative firms to create and capture value depends on innovations that are quickly and widely adopted. Yet, stakeholder concerns can establish important barriers to diffusion. We study the human capital aspect of this challenge and investigate whether innovative firms pay salary premiums to new hires with work experience from advocacy groups like Transparency International. We integrate strategic human capital with stakeholder theory and suggest that advocacy group experience creates signals for valuable human capital in terms of stakeholder knowledge and legitimacy transfers to innovative firms. Using matched data for 3,562 employees in Denmark, we find that new hires with advocacy group experience enjoy larger salary premiums at technologically leading firms, in occupations with direct stakeholder interaction, and for advocacy group top management. Managerial Summary: Innovation research is increasingly aware of the non-technological factors behind successful innovations. Users, regulators, or public opinion can be benevolent supporters or stingy opponents of innovations. Employees with an understanding of the needs and sensitivities of societal stakeholders should therefore be valuable to innovative firms. We find this to be the case when innovative firms hire employees from advocacy groups representing such stakeholders (e.g., Transparency International). Such employees receive higher salaries than an otherwise comparable reference group. These findings indicate that recruiting needs of innovative firms reward stakeholder experience, not merely technological expertise. They demonstrate how firms can create value in the pursuit of the public interest. Further, advocacy groups emerge as an important career stage allowing individuals to develop credible signals for stakeholder expertise

Unintended signals: Why companies with a history of offshoring have to pay wage penalties for new hires

We explore how companies with a history of offshoring attract their future employees. We reason that offshoring decisions send unintended signals about job insecurity to companies’ onshore labor markets. This signaling effect implies that offshoring companies must pay higher salaries for new hires than non-offshoring companies. We tested our predictions on a sample of 7971 matched managers and professionals recently hired by offshoring and non-offshoring companies. Our results indicate a 3–7% wage penalty for offshoring companies. Thus, we conclude that not only is offshoring challenging to implement, but it can also entail a number of general ramifications for the domestic labor market

Provision of foot health services for people with rheumatoid arthritis in New South Wales: a web-based survey of local podiatrists

Background: It is unclear if podiatric foot care for people with rheumatoid arthritis (RA) in New South Wales (NSW) meets current clinical recommendations. The objective of this study was to survey podiatrists' perceptions of the nature of podiatric foot care provision for people who have RA in NSW.Methods: An anonymous, cross-sectional survey with a web-based questionnaire was conducted. The survey questionnaire was developed according to clinical experience and current foot care recommendations. State registered podiatrists practising in the state of NSW were invited to participate. The survey link was distributed initially via email to members of the Australian Podiatry Association (NSW), and distributed further through snowballing techniques using professional networks. Data was analysed to assess significant associations between adherence to clinical practice guidelines, and private/public podiatry practices.Results: 86 podiatrists participated in the survey (78% from private practice, 22% from public practice). Respondents largely did not adhere to formal guidelines to manage their patients (88%). Only one respondent offered a dedicated service for patients with RA. Respondents indicated that the primary mode of accessing podiatry was by self-referral (68%). Significant variation was observed regarding access to disease and foot specific assessments and treatment strategies. Assessment methods such as administration of patient reported outcome measures, vascular and neurological assessments were not conducted by all respondents. Similarly, routine foot care strategies such as prescription of foot orthoses, foot health advice and footwear were not employed by all respondents.Conclusions: The results identified issues in foot care provision which should be explored through further research. Foot care provision in NSW does not appear to meet the current recommended standards for the management of foot problems in people who have RA. Improvements to foot care could be undertaken in terms of providing better access to examination techniques and treatment strategies that are recommended by evidence based treatment paradigms. © 2013 Hendry et al.; licensee BioMed Central Ltd

Delineamentos para uma teoria da Museologia

The guiding principles in the formulation of a Museology theory were established\ud and disseminated internationally from the mid-1980s, and are related to the creation of the\ud International Committee for Museology (Icofom), associated with the International Council of\ud Museums (Icom). The opinions regarding the nature of so-called museological knowledge\ud were issued under the very specific conditions of each groups composition and of the intellectual\ud work undertook in the occasion. Despite the difficulties with the wording, risen in tandem with\ud the exercise (the terminology problem), we focused on the conjuncture that surrounded the\ud formulation: the environment, the aims, the way in which it was composed and the foundations\ud that characterise it, as well as some of the discussions that took place, which revealed aspects\ud that have been handed down as a legacy in this field of specialization

Looking through the 'window of opportunity': is there a new paradigm of podiatry care on the horizon in early rheumatoid arthritis?

Over the past decade there have been significant advances in the clinical understanding and care of rheumatoid arthritis (RA). Major paradigm changes include earlier disease detection and introduction of therapy, and 'tight control' of follow-up driven by regular measurement of disease activity parameters. The advent of tumour necrosis factor (TNF) inhibitors and other biologic therapies have further revolutionised care. Low disease state and remission with prevention of joint damage and irreversible disability are achievable therapeutic goals. Consequently new opportunities exist for all health professionals to contribute towards these advances. For podiatrists relevant issues range from greater awareness of current concepts including early referral guidelines through to the application of specialist skills to manage localised, residual disease activity and associated functional impairments. Here we describe a new paradigm of podiatry care in early RA. This is driven by current evidence that indicates that even in low disease activity states destruction of foot joints may be progressive and associated with accumulating disability. The paradigm parallels the medical model comprising early detection, targeted therapy, a new concept of tight control of foot arthritis, and disease monitoring

First Results from the LUX Dark Matter Experiment at the Sanford Underground Research Facility

The Large Underground Xenon (LUX) experiment is a dual-phase xenon time-projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota). The LUX cryostat was filled for the first time in the underground laboratory in February 2013. We report results of the first WIMP search data set, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data with a fiducial volume of 118 kg. A profile-likelihood analysis technique shows our data to be consistent with the background-only hypothesis, allowing 90% confidence limits to be set on spin-independent WIMP-nucleon elastic scattering with a minimum upper limit on the cross section of 7.6 × 10−46 cm2 at a WIMP mass of 33 GeV=c2. We find that the LUX data are in disagreement with lowmass WIMP signal interpretations of the results from several recent direct detection experiments

Radio Frequency and DC High Voltage Breakdown of High Pressure Helium, Argon, and Xenon

[EN] Motivated by the possibility of guiding daughter ions from double beta decay events to single-ion sensors for barium tagging, the NEXT collaboration is developing a program of R&D to test radio frequency (RF) carpets for ion transport in high pressure xenon gas. This would require carpet functionality in regimes at higher pressures than have been previously reported, implying correspondingly larger electrode voltages than in existing systems. This mode of operation appears plausible for contemporary RF-carpet geometries due to the higher predicted breakdown strength of high pressure xenon relative to low pressure helium, the working medium in most existing RF carpet devices. In this paper we present the first measurements of the high voltage dielectric strength of xenon gas at high pressure and at the relevant RF frequencies for ion transport (in the 10MHz range), as well as new DC and RF measurements of the dielectric strengths of high pressure argon and helium gases at small gap sizes. We find breakdown voltages that are compatible with stable RF carpet operation given the gas, pressure, voltage, materials and geometry of interest.Woodruff, K.; Baeza-Rubio, J.; Huerta, D.; Jones, BJP.; Mcdonald, AD.; Norman, L.; Nygren, DR....
