Abstract
Purpose
The purpose of this paper is to design the geometrical structure of banana screen, and this study aims to improve the screen efficiency.
Design/methodology/approach
The discrete element method was used to simulate the sieving process of banana screen with the inclinations of decks improved by Fibonacci sequence. The effect of each deck along screen length on the screening efficiency of particles was studied in this paper.
Findings
The comparisons among three groups of industrial banana screens with five different consecutive Fibonacci numbers have been made, and the variations of fine particle ratio were also investigated. The results show that the banana screening improved by the 5 Fibonacci sequence, 3, 5, 8, 13 and 21, has the good screening performance in the simulation. It is found that the inclination degree of the first deck at the feed end is the key factor to determine screening efficiency of banana screens.
Practical implications
It is not possible to consider all real physical factors exactly in a virtual model. The experiment prototype of banana screen was used to simply verify the feasibility of the methodology.
Originality/value
This work is helpful for designing the geometric parameters of the curved screen and gives a broad perspective to improve the efficiency of banana screens.

Abstract
Purpose
The purpose of this paper is to present information from the Joint Health and Social Care Self-Assessment Framework (JHSCSAF) on reported rates of cervical cancer, breast cancer and bowel cancer screening for eligible people with learning disabilities in England in 2012/2013 compared to screening rates for the general population.
Design/methodology/approach
Between 94 and 101 Learning Disability Partnership Boards, as part of the JHSCSAF, provided information to allow the calculation of rates of cervical cancer, breast cancer and bowel cancer screening in their locality, for eligible people with learning disabilities and for the population as a whole.
Findings
At a national level, reported cancer screening coverage for eligible people with learning disabilities was substantially lower than for the population as a whole (cervical cancer screening 27.6 per cent of people with learning disabilities vs 70 per cent of total population; breast cancer screening 36.8 per cent of people with learning disabilities vs 57.8 per cent of total population; bowel cancer screening 28.1 per cent of people with learning disabilities vs 40.5 per cent of the general population). There were considerable geographical variations in reported coverage for all three screening programmes.
Originality/value
Consistent with previous research, localities in England report cancer screening rates for eligible people with learning disabilities considerably below those of the general population. There is an urgent need to address data availability and quality issues, as well as reasonable adjustments to cancer screening programmes to ensure uniformly high rates of cancer screening for people with learning disabilities across England.

Abstract
Purpose
Aims to establish the critical score and screening accuracy of the CAGE Questionnaire in three treatment settings – primary health care, walk‐in (triage) clinic and the emergency room.
Design/methodology/approach
Taguchi methods are applied to three screens of the CAGE questionnaire.
Findings
Analysis of the sensitivity and specificity data of three CAGE screens by leveling factor (p′), signal‐to‐noise ratios (S/N, SS/N) and their dependent relation resulted in critical CAGE scores of 1, 1 and 2; and high screening accuracy levels of 98.44, 97.20 and 94.92 percent, respectively. The illustrated method yielded excellent (≥95 percent) screening accuracy values for primary health care, emergency room and walk‐in clinic patients.
Originality/value
To reduce misclassification rates of alcohol abuse, screening systems should concentrate first on developing ways to standardize protocols. Further work is needed to establish high screening accuracy in other clinical settings, and particularly in those at risk of alcohol abuse in the general population.

Abstract
The purpose of this article is to show the importance of pre‐employment screening for hospitals. Pre‐employment screening in the hiring process is a must for hospitals, especially in the health care industry, where financial damages and lawsuits for hospitals recently increased because of negligent hiring. The information in this article is based on books about human resources in the health care industry, journals about medicine and law, and mostly articles from outsourced screening firms that provide service in the health care field. The scope of the article is to show the effectiveness of employee screening for hospitals in order to prevent or minimise lawsuits because of negligent hiring. Based on information about the benefits of employment screening in the health care industry, it is important for hospitals to implement “due diligence” by including screening programmes in their hiring process. The screening process can be done in‐house or be delegated to outside service providers that match the criteria. It is better to outsource these tasks so that hospitals can focus on other human resources tasks such as managing their employees to improve services for their visitors or customers.

Abstract
Purpose
The paper aims to present results of investigations carried out on the front electrode of the solar cell. The front-side electrode for solar cells based on crystalline material is obtained by the screen printing method. Screen printing has been the prevailing method of electrode deposition because of its low cost. One of the ways to improve the cell efficiency and reduce the production costs is a further refinement of the metal electrode screen printing process.
Design/methodology/approach
The researches were focused on the modification of mechanical parameters of screen printing process to ensure the best possible cross-section of the front electrode geometry. The main printing process parameters were constant, however, the print speed was variable. The obtained fine line of front contact was characterized morphologically – the dimension and geometry of the front contact cross-section – by scanning electron microscopy technique.
Findings
The thin paths of 100 μm in width were screen printed applying a new silver-paste made by Du Pont. The printing speed has significant effect on print quality in the way that the lower speed enhanced the printed results.
Research limitations/implications
For newest pastes (e.g. PV17D) influence of screen printing parameters on the front metallic electrodes geometry of solar cell is not so significant. Presented screen printing process can still give good results, but the further optimization for the new paste must be performed to achieve better cross-section geometry.
Originality/value
This paper confirms that one-step screen printing process can still give good results. The screen printed thin paths of 100 μm in width have good cross-section aspect ratio.

Abstract
Purpose
The purpose of this paper is to describe the role of the screening liaison nurses for adults with learning disabilities employed by Peninsula Community Health.
Design/methodology/approach
This paper reports on the national situation in regard to cancer screening for people with learning disabilities and explores the barriers which limit their participation in these screening programmes. It describes the screening liaison nurse role and presents case examples of the work they do.
Findings
The local screening rates for people with learning disabilities have increased since the creation of this role in 2011.
Originality/value
Increasing the uptake of cancer screening by people with learning disabilities is clearly in line with existing national priorities. To the author’s knowledge this is a unique role in this country and the authors propose that other areas would benefit from adopting this model of working.

Abstract
Purpose
It is widely established that many hiring managers view social networking websites (SNWs) such as LinkedIn and/or Facebook in the employment selection process, leading to the acceptance or rejection of job applicants. Due to the rapid evolution of social media, scientific study of SNWs has been substantially outpaced by organizational practice. This chapter focuses on a wide range of issues related to SNW screening relevant to research and practice.
Design/methodology/approach
The chapter: (1) reviews the current state of SNW screening practices, (2) describes a wide range of HR issues that should be considered such as privacy, discrimination, negligent hiring, validity, reliability, generalizability, impression management, applicant reactions, and utility, (3) draws connections to related issues already addressed by established employment selection methods to inform SNW screening, (4) discusses pros and cons of potential SNW screening approaches, and (5) provides a framework of best practices that should be incorporated into social network screening policies.
Findings
As an emerging employment selection approach, SNW screening demonstrates potential as a rich source of applicant information, but includes numerous legal and ethical issues. Further, these potential benefits and risks vary widely depending on the approaches used.
Originality/value
Provides HR practitioners with a wide range of information necessary to develop an effective social network screening policy, while making the case for academics to pursue research in this nascent area.

Abstract
Law on the screen goes beyond film. It takes us to the domains of mind and culture, power and politics, technology and rhetoric, and the changing contours and norms of professional practice, craft, and pedagogy. Law on the screen is a multidisciplinary affair. It embraces empirical/descriptive, political/normative, and jurisprudential/theoretical dimensions of scholarship. By codifying what we know and how we know it, culture and technology mimic the regulatory force of law. But just as law is shaped and informed by technology and culture so, too, are technology and culture shaped and informed in turn by law's power to regulate. Code is a two-way street. Who gets to design the code, how, and with what effect? That is the political question par excellence of our day.

Abstract
This study applies asymmetric rather than conventional symmetric analysis to advance theory in occupational psychology. The study applies systematic case-based analyses to model complex relations among conditions (i.e., configurations of high and low scores for variables) in terms of set memberships of managers. The study uses Boolean algebra to identify configurations (i.e., recipes) reflecting complex conditions sufficient for the occurrence of outcomes of interest (e.g., high versus low financial job stress, job strain, and job satisfaction). The study applies complexity theory tenets to offer a nuanced perspective concerning the occurrence of contrarian cases – for example, in identifying different cases (e.g., managers) with high membership scores in a variable (e.g., core self-evaluation) who have low job satisfaction scores and when different cases with low membership scores in the same variable have high job satisfaction. In a large-scale empirical study of managers (n = 928) in four (contextual) segments of the farm industry in New Zealand, this study tests the fit and predictive validities of set membership configurations for simple and complex antecedent conditions that indicate high/low core self-evaluations, job stress, and high/low job satisfaction. The findings support the conclusion that complexity theory in combination with configural analysis offers useful insights for explaining nuances in the causes and outcomes to high stress as well as low stress among farm managers. Some findings support and some are contrary to symmetric relationship findings (i.e., highly significant correlations that support main effect hypotheses).
