Assessing the potential economic benefits to farmers from various GM crops becoming available in the European Union by 2025: results from an expert survey
This paper reports on a study that identified a range of crop-trait combinations that are: agronomically suited to the EU; provide advantages to arable farmers and consumers; and are either already available in international markets, or advancing along the development pipeline and likely to become available by 2025. An expert stakeholder panel was recruited and asked for their views, using the Delphi approach, on the impact of these crop-traits on enterprise competitiveness, through changes to yields, production costs and product prices. In terms of input traits, there was consensus that traits such as herbicide tolerant/insect resistant (HT/IR) maize, HT sugar beet and HT soya bean would provide positive benefits for farmers. Output-side traits such as winter-sown rape with reduced saturated fats, were seen as offering benefits to consumers, but were either likely to be restricted to niche markets, or offer relatively modest price premia to farmers growing them. Our analysis of the financial impact of the adoption of GM crops more widely in the EU, showed that the competitiveness of the agricultural sector could well be improved by this. However, such improvements would be relatively small-scale in that large-scale national natural advantages from either economic or environmental conditions is unlikely to be overturned
The Role of Futureproofing in the Management of Infrastructural Assets
Ensuring long-term value from infrastructure is essential for a sustainable economy. In this context, futureproofing
involves addressing two broad issues:
i. Ensuring the ability of infrastructure to be resilient to unexpected or uncontrollable events e.g. extreme weather
events; and
ii. Ensuring the ability to adapt to required changes in structure and / or operations of the infrastructure in the future
e.g. expansion of capacity, change in usage mode or volumes.
Increasingly, in their respective roles, infrastructure designers/builders and owners/operators are being required to develop
strategies for futureproofing as part of the life cycle planning for key assets and systems that make up infrastructure.
In this paper, we report on a preliminary set of studies aimed at exploring the following issues related to infrastructure
/ infrastructure systems:
• What is intended by the futureproofing of infrastructural assets?
• Why and when to futureproof critical infrastructure?
• How can infrastructure assets and systems be prepared for uncertain futures?
• How can futureproofing be incorporated into asset management practice?
In order to seek answers to the above questions, the Cambridge Centre for Smart Infrastructure and Construction
(CSIC) has conducted two industrial workshops bringing together leading practitioners in the UK infrastructure
and construction sectors, along with government policy makers. This paper provides an initial summary of the
findings from the workshops (part presentation, part working sessions), and proposes a simple framework for linking
futureproofing into broader asset management considerations.
To begin, an overview of futureproofing and motivate the need for futureproofing infrastructure assets is provided.
Following this, an approach to futureproofing infrastructure portfolios is presented that organisations in the
infrastructure sector can use. Key barriers to futureproofing are also presented before examining the ISO 55001 asset
management standard to highlight the interplay between futureproofing and infrastructural asset management. Finally,
different ways by which an effective futureproofing strategy can enhance the value of infrastructure are examined

Evaluating the applicability of multi-agent software for implementing distributed industrial data management approaches
Distributed approaches to industrial control or information management problems are often tackled using Multi-agent methods. Multi-Agent systems – solutions resulting from taking a Multi-agent based approaches - often come with a certain amount of “overhead” such as communication systems, but can provide a helpful tool with the design and implementation. In this paper, a distributed data management problem is addressed with both a bespoke approach developed specifically for this problem and a more general Multi-agent approach. The two approaches are compared using architecture and software metrics. The software metric results show similar results, although overall the bespoke approach was more appropriate for the particular application examined. The architectural analysis indicates that the main reason for this difference is the communication and computation overhead associated with the agent-based system. It was not within the scope of this study to compare the two approaches under multiple application scenarios.BoeingThis is the author accepted manuscript.

Public Health Informatics in Local and State Health Agencies: An Update From the Public Health Workforce Interests and Needs Survey
OBJECTIVE:
To characterize public health informatics (PHI) specialists and identify the informatics needs of the public health workforce.
DESIGN:
Cross-sectional study.
SETTING:
US local and state health agencies.
PARTICIPANTS:
Employees from state health agencies central office (SHA-COs) and local health departments (LHDs) participating in the 2017 Public Health Workforce Interests and Needs Survey (PH WINS). We characterized and compared the job roles for self-reported PHI, "information technology specialist or information system manager" (IT/IS), "public health science" (PHS), and "clinical and laboratory" workers.
MAIN OUTCOME MEASURE:
Descriptive statistics for demographics, income, education, public health experience, program area, job satisfaction, and workplace environment, as well as data and informatics skills and needs.
RESULTS:
A total of 17 136 SHA-CO and 26 533 LHD employees participated in the survey. PHI specialist was self-reported as a job role among 1.1% and 0.3% of SHA-CO and LHD employees. The PHI segment most closely resembled PHS employees but had less public health experience and had lower salaries. Overall, fewer than one-third of PHI specialists reported working in an informatics program area, often supporting epidemiology and surveillance, vital records, and communicable disease. Compared with PH WINS 2014, current PHI respondents' satisfaction with their job and workplace environment moved toward more neutral and negative responses, while the IT/IS, PHS, and clinical and laboratory subgroups shifted toward more positive responses. The PHI specialists were less likely than those in IT/IS, PHS, or clinical and laboratory roles to report gaps in needed data and informatics skills.
CONCLUSIONS:
The informatics specialists' role continues to be rare in public health agencies, and those filling that role tend to have less public health experience and be less well compensated than staff in other technically focused positions. Significant data and informatics skills gaps persist among the broader public health workforce
Above all, do no harm: Towards more ethical ways of being and acting in psychological formulation
Recent evidence seems to suggest mental health service users can be at risk of persistent harm as a result of psychological interventions. This article analyses ways of addressing harm by using the ‘lenses’ of four ethical theories to view psychological formulation
The divergence of theoretical and actual designs in a holonic packing cell
The aim of this paper is to take the reader through the decisions made in designing a holonic system architecture to support customised packing of gift boxes with personal grooming (Gillette) products. The paper highlights issues that cause a divergence between a theoretical model of a holonic system and the approach that was actually encoded

New directions for warehousing data management research: Extensions to an existing review: Special session on 'Emerging technologies in logistics'
Existing research has conducted reviews of warehousing research and has suggested potential important areas for future work. In this paper we focus on warehousing data management-related issues and augment the findings from a recent review of warehousing research to suggest new areas of future work. To determine these potential areas we visited a large, national warehousing organisation and observed their warehouses, operations, and information systems. We compared our findings against the recommendations from an academic review, and identified five new areas of important future research.This is the author accepted manuscript.

The practical feasibility of using RFID in a metal environment
Passive Radio Frequency Identification (RFID) has revolutionized the way in which products are identified. This paper considers the effect of metals on the performance of RFID at ultra high frequency (UHF). The paper establishes read patterns in space, highlighting the interference of RF waves due to three different metals, one ferrous and the other two non ferrous, when placed behind a transponder. The effect of thickness of the metal plate is also examined. Different metals have been found to have different interference effects although there are some similarities in their read patterns related to their material properties. Also experiments have been carried out to identify and establish various methods of improving this performance. Finally, differences between performance-measuring parameters, namely attenuating transmitted power and calculating read rate at a fixed attenuation are established and possible reasons of these observations are presented
Overcoming limited dataset availability when working with industrial organisations
Increasing data security and privacy requirements combined with the need for additional data management research leads to a conflict for industrial companies. In order to solve their industrial data management problems companies need to share some of their data, but their internal confidentiality rules sometimes hamper this sharing process. Existing techniques for sharing data without releasing company secrets often loose some of the problems/characteristics within the data. This paper therefore presents a qualitative process to overcome this problem of industrial data sharing while still enabling external researchers to develop relevant solutions to organizational problems. It is based on initial trials with two industrial case studies and showed some promising results.BoeingThis is the author accepted manuscript.

Light response of pure CsI calorimeter crystals painted with wavelength-shifting lacquer
We have measured scintillation properties of pure CsI crystals used in the
shower calorimeter built for a precise determination of the pi+ -> pi0 e+ nu
decay rate at the Paul Scherrer Institute (PSI). All 240 individual crystals
painted with a special wavelength-shifting solution were examined in a
custom-build detection apparatus (RASTA=radioactive source tomography
apparatus) that uses a 137Cs radioactive gamma source, cosmic muons and a light
emitting diode as complementary probes of the scintillator light response. We
have extracted the total light output, axial light collection nonuniformities
and timing responses of the individual CsI crystals. These results predict
improved performance of the 3 pi sr PIBETA calorimeter due to the painted
lateral surfaces of 240 CsI crystals. The wavelength-shifting paint treatment
did not affect appreciably the total light output and timing resolution of our
crystal sample. The predicted energy resolution for positrons and photons in
the energy range of 10-100 MeV was nevertheless improved due to the more
favorable axial light collection probability variation. We have compared
simulated calorimeter ADC spectra due to 70 MeV positrons and photons with a
Monte Carlo calculation of an ideal detector light response.Comment: Elsevier LaTeX, 35 pages in e-print format, 15 Postscript Figures and
