G-RAM framework for software risk assessment and mitigation strategies in organisations
Authors: Biswas Baidyanath , Mukhopadhyay Arunabha 
Published: January 2018

PurposeMalicious attackers frequently breach information systems by exploiting disclosed software vulnerabilities. Knowledge of these vulnerabilities over time is essential to decide the use of software products by organisations. The purpose of this paper is to propose a novel G-RAM framework for business organisations to assess and mitigate risks arising out of software vulnerabilities.Design/methodology/approachThe G-RAM risk assessment module uses GARCH to model vulnerability growth. Using 16-year data across 1999-2016 from the National Vulnerability Database, the authors estimate the model parameters and validate the prediction accuracy. Next, the G-RAM risk mitigation module designs optimal software portfolio using Markowitz’s mean-variance optimisation for a given IT budget and preference.FindingsBased on an empirical analysis, this study establishes that vulnerability follows a non-linear, time-dependent, heteroskedastic growth pattern. Further, efficient software combinations are proposed that optimise correlated risk. The study also reports the empirical evidence of a shift in efficient frontier of software configurations with time.Research limitations/implicationsExisting assumption of independent and identically distributed residuals after vulnerability function fitting is incorrect. This study applies GARCH technique to measure volatility clustering and mean reversal. The risk (or volatility) represented by the instantaneous variance is dependent on the immediately previous one, as well as on the unconditional variance of the entire vulnerability growth process.Practical implicationsThe volatility-based estimation of vulnerability growth is a risk assessment mechanism. Next, the portfolio analysis acts as a risk mitigation activity. Results from this study can decide patch management cycle needed for each software – individual or group patching. G-RAM also ranks them into a 2×2 risk-return matrix to ensure that the correlated risk is diversified. Finally the paper helps the business firms to decide what to purchase and what to avoid.Originality/valueContrary to the existing techniques which either analyse with statistical distributions or linear econometric methods, this study establishes that vulnerability growth follows a non-linear, time-dependent, heteroskedastic pattern. The paper also links software risk assessment to IT governance and strategic business objectives. To the authors’ knowledge, this is the first study in IT security to examine and forecast volatility, and further design risk-optimal software portfolios.
Linking place attachment and social interaction: towards meaningful public places
Authors: Ujang Norsidah , Kozlowski Marek , Maulan Suhardi 
Published: January 2018

PurposeA public space is a place of significance when it fulfils the human need for social interaction and attachment. However, the scarcity of public spaces poses a challenge to support socialisation for people within a defined social and cultural group. The purpose of this paper is to explore the association between place attachment and social interaction within public spaces in the city centre of Kuala Lumpur, Malaysia.Design/methodology/approachFace-to-face interviews with urban users were conducted to examine the users’ engagement in three main public spaces in the city and the significance of these spaces to everyday social interaction. Field observations were carried out to examine patterns of users’ activities and interactions.FindingsThe authors uncover a lack of multi-functional spaces to support diverse forms of interactions in the city. A street has an important function to generate activities. However, spaces for people to sit and stay remain scarce, and are in most cases consumed by extended commercial use and thus considered private. Opportunities for social interaction are very limited. The significance of the places relates strongly to commercial and tourism functions, and hence place attachment evolves around those activities. Participants associated their familiarity and engagement with interaction between familiar people, close ethnic relationships and business acquaintances.Practical implicationsThe authors argue that more robust and socially responsive public spaces should be reclaimed for the culturally diverse users.Social implicationsDevelopment of attachment through meaningful spaces for people to stay and interact could enhance the role of public spaces in the city.Originality/valueBy understanding the social meanings of places, particularly in a multi-cultural setting, a stronger basis for designing and managing urban places towards resiliency and social sustainability can be provided.
How do university workers eat at the workplace?
Authors: Lima João , Costa Sofia , Rocha Ada 
Published: January 2018

Purpose
Food consumed at work can be brought from home or taken in private or university restaurants. Knowing the contribution of food consumption in the workplace allows for the identification of bad practices to modulate food availability in the work environment and raise consumer awareness for a more balanced food intake. This paper aims to characterize food consumption and to determine the contribution of food consumption at the workplace to daily food intake of employees of the University of Porto (UP).

Design/methodology/approach
A cross-sectional observational study was conducted. The project was approved by Ethical Commission of the UP. The principles of Helsínquia Declaration were respected and the workers under examine accept to participate in the study, through an inform consent. Data were obtained through the application of a self-administrated questionnaire and through the application of a questionnaire including a 24 h recall. There were assessed 513 individuals randomly selected, and the majority of them were women.

Findings
In total, 92.8 per cent of them preferred to have meals at the workplace that contributed to about 39.6 per cent of the daily energy intake. Reported food consumption at the workplace contributed about 42.6 per cent of carbohydrates, 39.4 per cent of total fat and 36.8 per cent of proteins for daily intake. A low intake of water (39.2 per cent of whole ingestion) and a huge amount and contribution of the workplace (48.4 per cent) to daily sugar intake was observed. Higher nutritional intake was observed for women (p < 0.05). The energy contribution of meals at the workplace is in accordance with recommendations, except for breakfast, that is below.

Originality/value
This work allows to characterize food habits of university employees at the workplace and the identification of the contribution of meals eaten at the workplace for daily energy and nutritional intake. These data allow to modulate food availability in the work environment and raise consumer awareness for a more balanced food intake.
Prediction of adulteration of game meat using FTIR and chemometrics
Authors: Moreira Maria Joao Pinho , Silva Ana , Saraiva Cristina , Marques Martins de Almeida José Manuel 
Published: January 2018

Purpose
Consumption of game meat is growing when compared to other meats. It is susceptible to adulteration because of its cost and availability. Spectroscopy may lead to rapid methodologies for detecting adulteration. The purpose of this study is to detect the adulteration of wild fallow deer (Dama dama) meat with domestic goat (G) (Capra aegagrus hircus) meat, for samples stored for different periods of time using Fourier transform infrared (FTIR) spectroscopy coupled with chemometric.

Design/methodology/approach
Meat was cut and mixed in different percentages, transformed into mini-burgers and stored at 3°C from 12 to 432 h and periodically examined for FTIR, pH and microbial analysis. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were applied to detect adulteration.

Findings
The PCA model, applied to the spectral region from 1,138 to 1,180, 1,314 to 1,477, 1,535 to 1,556 and from 1,728 to 1,759 cm−1, describes the adulteration using four principal components which explained 95 per cent of variance. For the levels of Adulteration A1 (pure meat), A2 (25 and 50 %w/wG) and A3 (75 and 100 %w/wG) for an external set of samples, the correlation coefficients for prediction were 0.979, 0.941 and 0.971, and the room mean square error were 8.58, 12.46 and 9.47 per cent, respectively.

Originality/value
The PLS-DA model predicted the adulteration for an external set of samples with high accuracy. The proposed method has the advantage of allowing rapid results, despite the storage time of the adulterated meat. It was shown that FTIR combined with chemometrics can be used to establish a methodology for the identification of adulteration of game meat, not only for fresh meat but also for meat stored for different periods of time.
Distance bias of socially responsible investment
Authors: Chen En Te , Nainggolan Yunieta Anny 
Published: January 2018

Purpose
Despite the benefits of international diversification, the home equity bias phenomenon is well documented in the portfolio choice literature. The purpose of this paper is to investigate whether the same investment behavior applies to domestic socially responsible investments (SRIs) where ethical screenings should be the selection criteria.

Design/methodology/approach
The authors apply the model by Coval and Moskowitz (1999), Grinblatt and Keloharju (2001) and Agarwal and Hauswald (2010) to uncover the effect of distance relative to screenings on SRI domestic portfolio choice. For the first time, the authors test the robustness of distance effect by using time bias, which is the travel time between the fund manager and the company’s headquarter.

Findings
The authors find that SRIs exhibit a strong preference for locally headquartered firms. After controlling for screening activity and other fund characteristics, the authors still find a strong distance bias in SRI fund portfolio decision-making. The authors find that this bias is mostly observed in SRI fund with social screening and that fund holding characteristics determine the propensity of fund managers to invest locally. The results suggest that the local bias puzzle exists in SRI.

Research limitations/implications
This study provides avenue for future research to examine whether the same local bias is found in SRI investment in other countries where they have different characteristics and behavior. Also, the evidence that local bias exists in SRI investment may need further analysis as to whether this is conflicting with the objectives of SRI, which focus more on ethical beliefs.

Practical implications
The results suggest that many local firms in the same city currently held by an SRI fund will not be held by this fund if it is in another city. The implications of the findings are that geographic proximity, along with ethical screenings, is an important dimension to how SRI fund invests.

Originality/value
This study is the first that examines local bias in SRI funds by using portfolio holding data.
The importance of CSR practices carried out by sport teams and its influence on brand love: the Real Madrid Foundation
Authors: Baena Verónica 
Published: January 2018

PurposeThis paper aims to to provide a better understanding of the effect that the corporate social responsibility (CSR) practices might have on brand love. It also analyzes the importance of making supporters be aware and involved in such initiatives.Design/methodology/approachThis study focuses on the Real Madrid Foundation, which is the most followed charitable sport institution worldwide. Data have been collected through a survey that was available online from January through April 2016. Participation has been solicited among the supporters of Real Madrid on fan sites. This produced a total of 402 completed questionnaires. In addition, the Managing Director of the Real Madrid Foundation has been interviewed.FindingsThe CSR activities carried out by the team positively influence fan commitment toward the club. Keeping the supporters updated about such initiatives through social networks also helps to increase the bonds between the club and its followers. Moreover, the fans’ use of the club’s website and their involvement in the club’s CSR activities may have a positive impact on the love the supporters profess toward the team’s brand. This claim, however, must be treated with some caution because it has not been proved to be statistically significant.Originality/valueThis study suggests that developing a website is not enough to get brand love from supporters. Experiential marketing does not seem to have statistical impact on brand love either. Conversely, the CSR actions and the use of social networks to keep followers updated about the social initiatives carried out by the team do provide new opportunities to achieve an emotional attachment toward the club and therefore, positively affect brand love.

Authors: Baldassarre Fabrizio Flavio , Ricciardi Francesca , Campo Raffaele 
Published: January 2018

PurposeThe purpose of this paper is to promote a business process approach for developing and improving the efficiency of hospital service quality in order to reduce clinical risks and increase patients satisfaction. The problems healthcare facilities face are how to reduce waste and risk and improve quality. The adoption of a process-focused organization could reduce organizational errors which have a negative influence on performance.Design/methodology/approachThe research is based on a case study methodology, analyzing a specific real-life case. It is shown a practical example in the surgery department of an Italian hospital, identifying, analyzing and managing critical situations, in terms of improvement. To this end, national and international contributions, public documents, institutional websites, conference papers, books, workshops and hospital websites have been analyzed. Moreover, other data were collected through questionnaires.FindingsResults show how a comprehensive view of the processes may lead to improvement in operations by identifying different risks and bottlenecks, suggesting the rapid implementation of corrective policies and improvements, in terms of overall efficiency.Practical implicationsBy implementing innovative organizational processes to identify and reduce bottleneck a healthcare system could achieve a competitive advantage.Originality/valueWithin the Italian healthcare system, limited attention has been paid to the design of healthcare facilities. Flexible solutions are necessary for lean management. The originality of this work lies in the analysis applied to a complex organization, through which hidden critical situations have been identified, and solutions to improve and provide better healthcare management have been suggested.
Novel cardiovascular magnetic resonance oxygenation approaches in understanding pathophysiology of cardiac diseases
Authors: Sree Raman Karthigesh , Nucifora Gaetano , Selvanayagam Joseph B 
Published: January 2018

SummaryCardiovascular magnetic resonance imaging (CMR) permits accurate phenotyping of many cardiac diseases. CMR’s inherent advantages are its non‐invasive nature, lack of ionizing radiation and high accuracy and reproducibility. Furthermore, it is able to assess many aspects of cardiac anatomy, structure and function. Specifically, it can characterize myocardial tissue, myocardial function, myocardial mass, myocardial blood flow/perfusion, irreversible and reversible injury, all with a high degree of accuracy and reproducibility. Hence, CMR is a powerful tool in clinical and pre‐clinical research. In recent years there have been novel advances in CMR myocardial tissue characterization. Oxygenation‐sensitive CMR (OS‐CMR) is a novel non‐invasive, contrast independent technique that permits direct quantification of myocardial tissue oxygenation, both at rest and during stress. In this review, we will address the principles of the OS‐CMR technique, its recent advances and summarize the studies in the effects of oxygenation on cardiac diseases.

Authors: Grytten Jostein , Skau Irene , Sørensen Rune , Eskild Anne 
Published: January 2018

ObjectiveTo examine the effect that the introduction of new diagnostic technology in obstetric care has had on fetal death.Data SourceThe Medical Birth Registry of Norway provided detailed medical information for approximately 1.2 million deliveries from 1967 to 1995. Information about diagnostic technology was collected directly from the maternity units, using a questionnaire.Study DesignThe data were analyzed using a hospital fixed‐effects regression with fetal mortality as the outcome measure. The key independent variables were the introduction of ultrasound and electronic fetal monitoring at each maternity ward. Hospital‐specific trends and risk factors of the mother were included as control variables. The richness of the data allowed us to perform several robustness tests.Principal FindingThe introduction of ultrasound caused a significant drop in fetal mortality rate, while the introduction of electronic fetal monitoring had no effect on the rate. In the population as a whole, ultrasound contributed to a reduction in fetal deaths of nearly 20 percent. For post‐term deliveries, the reduction was well over 50 percent.ConclusionThe introduction of ultrasound made a major contribution to the decline in fetal mortality at the end of the last century.

Authors: Gómez Inmaculada , Sarriés María Victoria , Ibañez Francisco C. , Beriain María José 
Published: January 2018

AbstractOlive and linseed oils have high contents of oleic acid and n‐3 fatty acids (FA), respectively. Vitamin D3, an essential nutrient, is in low contents in meat. This study investigated the potential application of olive and linseed oils’ mixture as a backfat replacer, and vitamin D3 as a supplement, in order to develop a product enriched by polyunsaturated FAs and vitamin D3. Two treatments were manufactured: conventional (C: 0% emulsion, 0 μg vitamin D3/100 g product) and modified (M: 10.9% emulsion/, 8.3 μg vitamin D3/100 g product). The quality characteristics and cooking effects on the FA and vitamin D3 contents were assessed. The sensory properties of cooked patties were not affected by olive and linseed oils’ mixture (P > 0.05). The instrumental textural parameters were lower in cooked M patties (P < 0.01), except springiness (P = 0.766) that was not affected by formulation. The contents of α‐linoleic acid in M patty were 19‐fold higher than those from C patty. The contents of n‐3 and n‐6 were higher in M patty (P < 0.05) than in C patty. Although cooking decreased the content of vitamin D3 in M patty (6.7 compared with 5.2 μg/100 g product), considerable increments were achieved compared to C patty.Practical ApplicationThere is an increasing demand of consumers for healthier meat products; therefore, the improvement of their nutritional profile without negatively affecting quality characteristics is key factor for meat sector. This study emphasizes the feasibility of using the combination of olive and linseed oils’ mixture and vitamin D3 to yield new meat products with high contents of polyunsaturated fatty acids and vitamin D3. The effectiveness of combination of oils mixture and vitamin D3 tested in this study is proven and the high contribution of vitamin D3 and some fatty acids of nutritional interest identified.

Authors: Zhai Xingchen , Yang Xin , Zou Pan , Shao Yong , Yuan Shoujun , Abd El‐Aty A. M. , Wang Jing 
Published: January 2018

AbstractChitosan oligosaccharides (COS), hydrolyzed products of chitosan, was found to display various biological activities. Herein, we assessed the immunostimulatory activity of COS both in in vitro and in vivo studies. In vitro cytotoxicity studies to murine macrophage RAW264.7 revealed that COS is safe even at the maximum tested concentration of 1000 μg/mL. It also stimulates the production of nitric oxide (NO) and tumor necrosis factor (TNF‐α) and enhances the phagocytosis in COS‐stimulated RAW264.7. We have shown that the COS could significantly (P < 0.05) restore the reduced immune organs indices, phagocytic index, lymphocyte proliferation, natural killer cell activity, and antioxidant enzyme activities in a cyclophosphamide‐induced immunosuppressed mice model. COS can also improve the survival rate in irradiation injury mice and significantly (P < 0.05) increased the spleen indices and up‐regulates the CD4+/CD8+ ratio in splenocytes. In sum, the aforementioned results suggest that COS might has the potential to be used as an immunostimulatory agent in patients with immune dysfunctions or be a model for functional food development.Practical ApplicationCOS might has the potential to be used as an immunostimulatory agent in patients with immune dysfunctions or be a model for functional food development.

Published: January 2018

BackgroundIn‐bed cycling (IBC) is gaining interest for implementation in intensive care units. Our main objective was to explore patient recollections and experiences of early mobilization, including IBC. Secondly, we aimed to examine if IBC was safe and feasible.MethodsEleven participants were interviewed about their experiences during their critical illnesses and active mobilization in the intensive care unit. The interviews were analyzed thematically. Six participants were also monitored for physiological reactions and adverse events during IBC while mechanically ventilated.ResultsFrom the interviews, one main theme with three subthemes was identified. The main theme was: Early mobilization gave a direction toward normalization. The three subthemes were: (1) IBC gave a feeling of control over recovery early on during the critical illness (2) Early mobilization, including IBC, with continuous support from health care professionals gave a feeling of safety and hope for recovery for the patient; and (3) Unpleasant experiences and disorientation were felt during the critical illness and IBC. Furthermore, IBC did not induce large physiological changes or major adverse events in the participants who were monitored for feasibility and safety.ConclusionsPatient interviews indicated that the patients’ participation in early mobilization with emphasis on IBC motivated them to be active in their recovery to regain a good level of health after their earlier critical illness during their intensive care stay. IBC was, in this small study, safe and feasible in the two participating intensive care units.
