Risk factors of social assistance transitions: a case-control study for Germany
Authors: Fuchs Benjamin 
Published: November 2017

PurposePoverty transitions can be explained by two opposing theories: the traditional sociological approach that focusses on social stratification and individualisation theory, which emphasises on life course risks for all strata. Both perspectives have been investigated extensively for income poverty while neglecting other important poverty indicators, such as deprivation or the receipt of social assistance. The purpose of this paper is to focus on the latter to investigate the impact of social stratification (e.g. social class), life course risks (e.g. health problems), and their interactions on the probability of social assistance entry for Germany.Design/methodology/approachThe analysis utilises survey data containing a sample of first-time social assistance entrants and a sample of the residential population. Applying case-control methodology, logistic regression is conducted to model the impact of social stratification determinants, life course risks, and their interactions on the probability of social assistance entry.FindingsSocial stratification determinants, particularly social class, have a significant effect. However, their effect is weaker than the effect of life course risks. Contrary to the prediction of individualisation theory, the poverty-triggering impact of life course risks varies substantially by social stratum. The combination of both theories yields high predictive power.Originality/valueThis paper is the first to comprehensively test social stratification and individualisation theory with respect to social assistance receipt as a poverty indicator. It is the first paper that investigates the entire population at risk of social assistance entry in Germany.

Continued value creation in crowdsourcing from creative process engagement
Authors: Piyathasanan Bhuminan , Mathies Christine , Patterson Paul G. , de Ruyter Ko 
Published: November 2017

Purpose
Crowdsourcing delivers creative ideas for the issuing firm, but participants’ engagement in the creative process also creates additional benefits to firms and participating customers. The purpose of this study is to investigate if these spill-over values endure over time. With data from two time point, i.e. at submission and after announcement of the contest winners, we examine the relationship between the degree of a participant’s creative process engagement (CPE) and value creation from a crowdsourcing contest, and how these perceptions of value change over time.

Design/methodology/approach
Data were collected from 154 participants in a crowdsourcing contest at two time points with an online survey: at submission, and after receiving feedback (in term of rankings, rewards, and comments) from the community. Partial Least Square path modelling was used to estimate both main and moderating effects.

Findings
CPE increases the perceived value of customers (social and epistemic value) and firms alike (knowledge-sharing intention and customer loyalty), though all but epistemic values decrease over time. Disconfirmation of expectations and need for recognition moderate these effects.

Originality/value
This paper is the first longitudinal study that helps understanding the effect of CPE on value creation from crowdsourcing across time. It also uses the theoretical lens of the honeymoon hangover effect to explain how perceived value changes. The resulting insights into the role of customer engagement in crowdsourcing contests and subsequent value creation will be beneficial to the growing research stream on consumer value co-creation and user innovation.
Disgust images and nonprofit children’s causes
Authors: Allred Anthony T. , Amos Clinton 
Published: November 2017

Purpose
The purpose of this study is to examine the usefulness of disgust imagery in a nonprofit organization context as one part of the broader social marketing paradigm.

Design/methodology/approach
An experiment was conducted in the child victim segment of the market using disgust and nondisgust images. Data were collected from 167 subjects via Amazon’s Mechanical Turk. Dependent variables measured included donation intention, empathy and guilt. Control variables included religiosity and attitude toward helping others, along with demographic factors.

Findings
MANCOVA results indicate that while the disgust image evoked greater empathy, the nondisgust image evoked greater donation intentions. The disgust image had a nonsignificant effect on the level of guilt felt by subjects. Mediation analysis indicates that empathy serves as a competitive mediator for the disgust–donation intentions relationship.

Research limitations/implications
This study examines the effects of disgust images on empathy, guilt and donation intentions. Although the findings indicate a contrasting effect of disgust on empathy and donation intentions, more research is needed to validate these findings with diverse samples, contexts and various donation behavior measures. Regarding charitable giving, the current findings suggest caution should be used when using disgust images to evoke empathy, as the tactic may also negatively affect donation intentions.

Social implications
Nonprofits that effectively apply marketing can change individual and community behavior. To continue their work, they rely on donors and volunteers. This study provides social marketers.

Originality/value
Past research has demonstrated the effectiveness of disgust appeals for deterring behavior. In contrast, this research provides unique insights into disgust appeals as a catalyst for motivating behavior. This research provides a much-needed empirical evaluation of disgust appeals in a social marketing context.
Look before you LIEEP
Authors: Gordon Ross , Butler Katherine , Cooper Paul , Waitt Gordon , Magee Christopher 
Published: November 2017

Purpose
This paper aims to present a discursive and evaluative analysis of Energy + Illawarra, an Australian Government Low Income Energy Efficiency Program (LIEEP) funded interdisciplinary social marketing energy efficiency programme. Energy + Illawarra was a community programme working with low-income older people in Australia and involving social marketers, human geographers and engineers. The paper aims to identify how ecological systems theory can inform social marketing, and what practicalities there may be in doing so. The paper also aims to assess whether a social marketing programme that draws on ecological systems theory can have a positive impact on people’s thermal comfort.

Design/methodology/approach
First, the paper uses critical discursive analysis to examine the use of various elements of a social marketing energy efficiency programme in relation to the different levels of ecological systems theory. Second, a longitudinal cohort survey study design is used to evaluate the programme’s influence on people’s perceptions of thermal comfort and satisfaction with thermal comfort in their homes.

Findings
The study found that ecological systems theory could be an effective framework for social marketing programmes. The evaluation study found that the intervention had a positive impact on participant’s perceptions of thermal comfort, satisfaction with thermal comfort and attitudes towards energy efficiency. However, the paper identifies some potential tensions in using ecological systems theory and suggests that issues of power, representation, agenda setting, the need for reflexive practice and consideration of unintended consequences are important considerations in social marketing programmes.

Originality/value
The work presented here suggests that multi-level social marketing programmes that draw on ecological systems theory can make a useful contribution to social change as demonstrated by the evaluation survey finding positive impacts on thermal comfort and attitudes of participants. However, issues of power, representation, agenda setting, the need for reflexive practice and consideration of unintended consequences should be considered in social marketing programmes.
Traffic systems in smart cities using LabVIEW
Authors: Farooq Aqeel , Alhalabi Wadee , Alahmadi Sara M. 
Published: November 2017

Purpose
The purpose of this research work is to design and apply LabVIEW in the area of traffic maintenance and flow, by introducing improvements in the smart city. The objective is to introduce the automated human–machine interface (HMI) – a computer-based graphical user interface (GUI) – for measuring the traffic flow and detecting faults in poles.

Design/methodology/approach
This research paper is based on the use of LabVIEW for designing the HMI for a traffic system in a smart city. This includes considerable measures that are: smart flow of traffic, violation detection on the signal, fault measurement in the traffic pole, locking down of cars for emergency and measuring parameters inside the cars.

Findings
In this paper, the GUIs and the required circuitry for making improvements in the infrastructure of traffic systems have been designed and proposed, with their respective required hardware. Several measured conditions have been discussed in detail.

Research limitations/implications
PJRC Teensy 3.1 has been used because it contains enough general-purpose input–output (GPIO) pins required for monitoring parameters that are used for maintaining the necessary flow of traffic and monitor the proposed study case. A combination of sensors such as infrared, accelerometer, magnetic compass, temperature sensor, current sensors, ultrasonic sensor, fingerprint readers, etc. are used to create a monitoring environment for the application. Using Teensy and LabVIEW, the system costs less and is effective in terms of performance.

Practical implications
The microprocessor board shields for placing actuators and sensors and for attaching the input/output (I/O) to the LED indicators and display have been designed. A circuitry for scaling voltage, i.e. making sensor readings to read limits, has been designed. A combination of certain sensors, at different signals, will lead to a secure and more durable control of traffic. The proposed applications with its hardware and software cost less, are effective and can be easily used for making the city’s traffic services smart. For alarm levels, the desired alarm level can be set from the front panel for certain conditions from the monitoring station. For this, virtual channels can be created for allowing the operator to set any random value for limits. If the sensor value crosses the alarm value, then the corresponding alarm displays an alert. The system works by using efficient decision-making techniques and stores the data along with the corresponding time of operation, for future decisions.

Originality/value
This study is an advanced research of its category because it combines the field of electrical engineering, computer science and traffic systems by using LabVIEW.
English vocabulary learning through recommender system based on sentence complexity and vocabulary difficulty
Authors: Okhdar Mahboub , Ghaffari Ali 
Published: November 2017

Purpose
Based on consideration of learner needs for expanding vocabulary and the complexity of educational content, this paper introduces a model aimed at facilitating English vocabulary learning.

Design/methodology/approach
By measuring a set of effective variables regarding simplicity of English sentences, a ranking algorithm is presented in the proposed model. According to this ranking, the simplest sentence in the recommender system (RS) is selected and recommended to the user. Furthermore, Pearson correlation coefficient was used for checking the degree of correlation among the respective parameters on sentence simplicity. For evaluating the efficiency of the recommended algorithm, a prototype was designed by programming using Embarcadero Delphi XE2.

Findings
The results of the study indicated that the correlation among the parameters of word frequency, sentence length and average dependency distance were 0.723, 0.683 and 0.589, respectively. The computed final score is considered to be more accurate.

Practical implications
The application of RS in language learning and education sheds light on the theoretical validity of system thinking by highlighting its key features: its multidisciplinary nature, complexity, dynamicity and the interdependence and relation of micro and macro levels in a system.

Social implications
The proposed method has significant pedagogical implications; it can be used by second language teachers and learners for checking the degree of complexity/learnability of discourse and text.

Originality/value
This paper proposes an alternate model with a significantly higher speed for computing final sentence score.
“Well it is for their sake we are here”: meaningful work tasks from care workers’ view
Authors: Vidman Åsa , Strömberg Annika 
Published: November 2017

Purpose
Employees in elderly care have a high rate of sick leave. One explanation is that employees that experience a low level of meaning of work are at a higher risk for long-term sick leave. The paper aims to discuss these issues.

Design/methodology/approach
This qualitative interview study aims to examine what employees in residential care facilities experience as the meaningful aspects of their work tasks. Interviews with 14 persons employed in residential care facilities were conducted.

Findings
The findings show that meaningful work tasks are about organizing the work to make use of the creativity and knowledge of the staff in order to support relations with older people.

Originality/value
The knowledge about what constitutes a healthy work environment is not as comprehensive as it is about what constitutes health risks. Furthermore, these issues have been considered by only a few qualitative studies about social care in the field of sick leave. Therefore, this qualitative interview study examines what employees in residential care facilities experience as meaningful aspects of their work tasks.
Peptides Derived from Foods as Supportive Diet Components in the Prevention of Metabolic Syndrome
Authors: Iwaniak Anna , Darewicz Małgorzata , Minkiewicz Piotr 
Published: November 2017

AbstractMetabolic syndrome (MSyn) includes physiological, biochemical, clinical, and metabolic abnormalities, leading to an increase in health problems like obesity, dyslipidemia, cardiovascular diseases, and diabetes, which contribute to an increase in mortality rate. One of the main factors having a key impact on our health is the food we consume. Thus, scientists work towards the discovery of novel bioactive compounds with therapeutic potential to address MSyn. According to scientific reports, peptides derived from food proteins exhibit bioactivities important for the prevention of MSyn diseases; that is, they regulate blood pressure and glycemia; reduce cholesterol level and body mass; and scavenge free radicals. The aim of this review is to study the potential role of peptides in the prevention of MSyn. Particularly peptides which exhibit the following activities: antihypertensive [angiotensin‐converting enzyme (ACE) inhibition (EC 3.4.15.1)], antidiabetic [dipeptidyl peptidase IV (DPP‐IV) (EC 3.4.14.5)/α‐glucosidase (EC 3.2.1.20)/α‐amylase (EC 3.2.1.1) inhibition)], cholesterol level reduction, antioxidative, and obesity prevention, were studied. If possible, special attention is paid in the review to the bioactivities of peptides that were measured in vivo. Some examples of peptides showing dual or multiple action against MSyn targets are presented. Moreover, using the database of bioactive peptide sequences (BIOPEP) we made a list of peptides serving simultaneous functions in counteracting MSyn dysfunctions. Such an approach may simplify the discovery of MSyn preventive peptides, as well as highlight some of them as potent bioactive ingredients that may be incorporated into foods. Moreover, the research strategy involving the in silico and in vitro/in vivo methodologies may be useful in the production of food protein hydrolysates supporting the treatment of MSyn dysfunctions.

Published: November 2017

AbstractThe objective of this study was to investigate the physicochemical properties and changes in the microbial counts of boiled salted duck (BSD) meat packed under various conditions. BSD meat was stored under normal atmosphere (C) and two modified atmosphere packaging (MAP) conditions: M1 (N2, 100%) and M2 (CO2/N2, 30%/70%) at 4 °C. Microbiological quality, pH, redness, lipid oxidation, headspace gas composition, and water activity of BSD meat were measured. The results showed that the time to reach the maximum acceptable total viable counts (TVC, 4.9 log CFU/g) was 12, 18, and 21 d in C, M1, and M2 samples, respectively. Significant difference in the redness values was observed in all treatments during storage. The redness value of C group was significantly lower than that in M1 and M2 groups at the end of storage. The thiobarbituric acid‐reactive substances (TBARS) values under MAP were 0.24 to 0.26 mg MDA/kg meat at the end of storage, lower (P < 0.05) than that in C group (0.78 mg MDA/kg meat). The water activity in M2 group was the lowest among all 3 groups. The CO2 concentration in M2 decreased significantly during storage. Our study demonstrates that packaging with 30% CO2 and 70% N2 (M2) could extend the shelf‐life of BSD meat to 21 d during storage at 4 °C, suggesting that MAP can be a practical approach to extend the shelf‐life and maintain the quality of BSD products.Practical ApplicationThis study evaluated the application of MAP for a cooked duck product. Our results showed that MAP can be utilized to extend the shelf‐life. This technology may be used for preservation of other cooked meat products.
Towards a Kieselguhr‐ and PVPP‐Free Clarification and Stabilization Process of Rough Beer at Room‐Temperature Conditions
Authors: Cimini Alessio , Moresi Mauro 
Published: November 2017

AbstractIn this work, the main constraint (that is, beer chilling and chill haze removing) of the current beer conditioning techniques using Kieselguhr filtration and Polyvinylpolypyrrolidone (PVPP) treatment was overcome by developing a novel higher‐throughput conditioning process, operating at room temperatures with no use of filter aids. The effect of filtration temperature (TF) in the range of 0 to 40 °C on the hydraulic permeability of ceramic hollow‐fiber (HF) membranes with nominal pore size of 0.2 to 1.4 μm, as well as on their limiting permeation flux (J*) when feeding precentrifuged rough beer, was preliminarily assessed. When using the 1.4‐μm HF membrane operating at TF ≥ 20 °C, it was possible to enhance the average permeation flux at values (676 to 1844 L/m2/h), noticeably higher than those (250 to 500 L/m2/h) characteristics of conventional powder filtration. Despite its acceptable permanent haze, the resulting beer permeate still exhibited colloidal instability. By resorting to the commercial enzyme preparation Brewers Clarex® before beer clarification, it was possible to significantly improve its colloidal stability as measured using a number of European Brewing Convention forcing tests, especially with respect to that of precentrifuged rough beer by itself. By combining the above enzymatic treatment with membrane clarification at 30 °C across the ceramic 1.4‐μm HF membrane module, it was possible to limit the haze development due to chilling, sensitive proteins, and alcohol addition to as low as 0.78, 4.1, and 4.0 EBC‐U, respectively, the enzymatic treatment being by far more effective than that using PVPP.Practical ApplicationA novel Kieselguhr‐ and PVPP‐free rough beer conditioning process at room temperatures was set up. By submitting precentrifuged rough beer to commercial preparation Brewers Clarex ® and then to membrane clarification at 30 °C across a ceramic 1.4‐μm hollow‐fiber membrane module, it was possible to obtain a clear and stable beer with a throughput (1306 ± 72 L/m2/h) by far higher than that (250 to 500 L/m2/h) characterizing the current powder filters. The haze development due to chilling, sensitive proteins, and alcohol adding was by far lower than that observed when microfiltering PVPP‐pretreated rough beer.

Published: November 2017

BackgroundThis prospective, randomised, controlled study was performed to evaluate the usefulness of the McGrath VL compared with Macintosh laryngoscopy in children with expected normal airway during endotracheal intubation, by comparing the time to intubation and difficulty of intubation.MethodsEighty‐four patients aged 1–10 years who underwent endotracheal intubation for elective surgery were randomly assigned to the McGrath group (n = 42) or the Macintosh group (n = 42). Anaesthesia was induced with 2.5–3.0 mg/kg of propofol and sevoflurane 5–8 vol%. Orotracheal intubation was performed 2 min after injection of rocuronium 0.6 mg/kg with McGrath VL or Macintosh laryngoscope; the primary outcome was the time to intubation. The Cormack and Lehane glottic grade, intubation difficulty score (IDS), and success rate on intubation were assessed. Haemodynamic changes were also recorded.ResultsAs the primary outcome, median time to intubation [interquartile range] did not differ between the McGrath group and the Macintosh group (25.0 [22.8–28.3] s vs. 26.0 [24.0–29.0] s, P = 0.301). The incidence of grade I glottic view was significantly higher in the McGrath group than in the Macintosh group (95% vs. 74%, P = 0.013). Median IDS was lower in the McGrath group than in the Macintosh group (0 [0–0] vs. 0 [0–1], P = 0.018). There were no significant differences in success rate on intubation or haemodynamics between the two groups.ConclusionsMcGrath VL provides better laryngeal views and lower IDS but similar intubation times and success rates compared with the Macintosh laryngoscope in children with normal airway.
