How effective are social engineering interventions? A meta-analysis
Authors: Bullee Jan-Willem , Junger Marianne 
Published: August 2020

PurposeSocial engineering is a prominent aspect of online crime. Various interventions have been developed to reduce the success of this type of attacks. This paper aims to investigate if interventions can help to decrease the vulnerability to social engineering attacks. If they help, the authors investigate which forms of interventions and specific elements constitute success.Design/methodology/approachThe authors selected studies which had an experimental design and rigorously tested at least one intervention that aimed to reduce the vulnerability to social engineering. The studies were primarily identified from querying the Scopus database. The authors identified 19 studies which lead to the identification of 37 effect sizes, based on a total sample of N = 23,146 subjects. The available training, intervention materials and effect sizes were analysed. The authors collected information on the context of the intervention, the characteristics of the intervention and the characteristics of the research methodology. All analyses were performed using random-effects models, and heterogeneity was quantified.FindingsThe authors find substantial differences in effect size for the different interventions. Some interventions are highly effective; others have no effect at all. Highly intensive interventions are more effective than those that are low on intensity. Furthermore, interventions with a narrow focus are more effective than those with a broad focus.Practical implicationsThe results of this study show differences in effect for different elements of interventions. This allows practitioners to review their awareness campaigns and tailor them to increase their success.Originality/valueThe authors believe that this is the first study that compares the impact of social engineering interventions systematically.

Published: August 2020

PurposeBased on the DVS1608-2011 and IIW-2008 and BS EN15085-3 standards, the stress state grade of welded joints of aluminum alloy EMU (Electric Multiple Units) body was studied.Design/methodology/approachFirst, the calculation methods of the stress state grade of aluminum alloy welded joints analyzed by DVS1608-2011 and IIW-2008 standards were studied, and the two methods were programmed by the APDL language of ANSYS. Then, the finite element model of aluminum alloy EMU body was established; the static strength calculation result of the body was compared with the test result, and the error is basically within 10%. Finally, under the acceleration fatigue load provided by BS EN12663 standard, the fatigue analysis was carried out on the welded joint of the vehicle body, and the stress state of the welded joint of the vehicle body was studied according to IIW-2008 and DVS1608 standards, respectively.FindingsThe results show that the assessment method based on IIW-2008 standard is more rigorous, and the maximum stress factor of the longitudinal weld between the side beam and the side wall is 0.811; the position occurs in the area where the longitudinal weld of the side beam and the side wall is close to the lower door angle.Originality/valueThe stress state is medium, and the rest of the weld stress states are low.
Addressing the contamination issue in collaborative consumption of fashion: does ownership type of shared goods matter?
Authors: Kim Naeun Lauren , Jin Byoungho Ellie 
Published: August 2020

PurposeOne of the major concerns in the emerging phenomenon of collaborative consumption (CC) is the issue of contamination (i.e. feeling “grossed out” when sharing items with others). Guided by the law of contagion and the consumer contamination effect theory, this research investigated the ways in which companies can manipulate in order to reduce the negative contamination when renting or purchasing used fashion items from others. Specifically, this research examines this issue of contamination through the ownership type of the shared goods (e.g. corporate-ownership or B2C exchange, and consumer-ownership or C2C exchange) and its effect on consumers' CC intentions in two distinct sharing contexts (i.e. rental and secondhand purchase).Design/methodology/approachA total of 181 American female consumers were assigned to an experimental CC scenario, and their rental/secondhand purchase intentions were compared through ANCOVA analysis.FindingsIn both rental and secondhand purchase contexts, consumers displayed greater intentions to shop in B2C setting (i.e. corporate-ownership) with no direct contact with the previous owner, than in C2C setting (i.e. consumer-ownership) with a greater association with the previous owner and the shared items. Such inclination was more prevalent when purchasing a shirt than a handbag, suggesting that consumers feel more grossed out when there is greater physical contact with the shared item.Originality/valueThe findings of the study suggest a possible solution to alleviate the contamination effect, and the discovery of the degree of contact as a moderator provides new insight into contamination research.

Published: August 2020

PurposeThe objectives of this study is first to assess the effect of organizational antecedents on knowledge management capability and its effect on innovation strategy through the moderating effect of environmental dynamism.Design/methodology/approachThe data were collected from SMEs in central region of Malaysia through a cross-sectional survey of 202 owners and analyzed through structural equation modeling using SmartPLS software.FindingsThe results show that while formal structure, selection policies, incentives and training and development policies have positive affect on knowledge management capability, there is no effect of innovation culture on knowledge management capability. Knowledge management capability has a positive and significant effect on innovation strategy. Interestingly, the findings show that environmental dynamism strengthens the positive effect of knowledge management capability on innovation strategy.Practical implicationsThe findings of this study emphasize on the potential of collaboration among people for creating effective knowledge sharing in organizations and modalities in order to successfully design a collaborative knowledge-based work environment.Originality/valueThe model links organizational antecedents with knowledge management capability and the critical role of knowledge management capability on innovation strategy of SMEs considering environmental dynamism.
Couples’ experiences of using DemPower in everyday life
Authors: Bielsten Therése , Keady John , Kullberg Agneta , Lasrado Reena , Hellström Ingrid 
Published: August 2020

Purpose
Interventions aimed at couples where one partner has dementia are often targeting burden, depression and cognitive function and do not focus on relationship and interpersonal issues. Furthermore, interventions within this population do not seem to have embraced a salutogenic and authentic dyadic approach where both partners’ experiences are considered. To address this gap, a self-management app, DemPower, which was piloted and tested among couples where one partner has dementia living at home, has been developed. This study explores couples‘ everyday experiences of engaging with the DemPower.

Design/methodology/approach
Semi-structured interviews with couples were analysed using thematic analysis.

Findings
The findings resulted in the following themes: growth of the relationship; we are not alone; and positive approach. The findings indicated that the experiences of a salutogenic and dyadic intervention can contribute to the feelings of empowerment, satisfaction of couples’ achievements and a sense of support through peers and with the intervention itself.

Originality/value
The findings of this study indicate that couples where one partner has dementia appreciate interventions that focuses on a salutogenic approach to their everyday life and relationship. The dyadic intervention contributed to feelings of empowerment, satisfaction of couples’ achievements and a sense of support through peers and through the intervention itself. Discussing, inventory and focus on strengths, resources and quality of life can therefore give couples insight in their growth of the relationship and their transitions during the dementia trajectory. Furthermore, this study can serve as an eye opener in health care for the type of support couples need and wishes to receive. This means that care for people with dementia and partners should adopt a more health-promoting approach.
The role of universities in times of crisis: a vice-chancellor's perspective
Authors: Dewar John 
Published: August 2020

PurposeUniversity responses to crises range from providing practical support to affected students and staff; providing leadership to the community; contributing to the development of government policy; developing new knowledge; establishing new qualifications to reskill the workforce in areas of need; and working with industry partners to solve commercial and manufacturing problems.Design/methodology/approachUniversities play a vital role in times of crisis. This undertaking is exemplified by the important contribution made by universities to the societal response to recent crisis events including bushfires and the COVID-19 pandemic. It is not surprising that universities play this role, however, because it is a natural extension of a modern university's mission of promoting sustainable development and making positive contributions to the communities which it serves. Importantly, the role of universities is multifaceted and encompasses both applied and theoretical elements.FindingsEach of these responses demonstrates the way that modern universities have become permeable institutions that are responsive to society and the people around them.Originality/valueThis is an original opinions piece.
Income comparison and happiness: The role of fair income distribution
Authors: Chen Yongwei , Fu Dahai , Ye Xinyue 
Published: August 2020

AbstractRelative income gap is one of the most popular approaches for explaining the income–happiness relationship. We argue in this article that when people compare their incomes, they care about distributional fairness more than relative income disparity. It is difficult for us to explain China's income–happiness paradox if we simply compare the income gap and do not explore the income‐generation process leading to income inequality. We therefore employ an approach based on a responsibility‐sensitive theory of justice that decomposes individual income into fair and unfair components. As a proxy for distributional unfairness, unfair income is considered the main source of unhappiness. Using data from the Chinese Household Income Project survey, we find strong support for the negative relationship between income unfairness and happiness. We also find a significantly positive relationship between the relative income gap and income unfairness, which leads us to consider the income comparison hypothesis as the explanation for the income–happiness paradox in a new light. Sensitivity analyses confirm the robustness of our results.
Local house price comovements
Authors: Fischer Marcel , Füss Roland , Stehle Simon 
Published: August 2020

AbstractWe study the microlevel evolution of residential house prices using data on repeat sales on Manhattan Island from 2004 to 2015. We document that price comovement, even within a ZIP code, is a highly local and persistent phenomenon. The strength of such comovements vanishes with both spatial and temporal distance. Local underperformance is more persistent than local overperformance, particularly when house prices on aggregate level increase.
Rib Variation at Multiple Locations and Implications for Histological Age Estimation*
Authors: Dominguez Victoria M. , Harden Angela L. , Wascher Matthew , Agnew Amanda M. 
Published: August 2020

AbstractExisting histological age estimation methods using the rib were developed mainly from the midshaft; however, in forensic practice, uncertainty of sampling location often arises due to fragmented or previously sampled ribs. The potential for error increases when sampling location is uncertain and utilizing a section beyond the midshaft (either anterior or posterior) may result in erroneous age estimates. Additionally, there is debate within the field regarding the minimum number of sections needed for accurate age estimation. The aim of this research is to determine the importance of the midshaft distinction for age‐at‐death assessment and the necessity of analyzing serial sections by evaluating histological variables at sampling locations along the length of the rib. Three seriated histological sections at three sampling locations (anterior, midshaft, and posterior) were obtained from sixth ribs of ten postmortem human subjects. Cortical area (Ct.Ar) and osteon population density (OPD) were collected from each section (n = 90). Significant differences were determined in Ct.Ar between sampling locations, demonstrating the variation present along the length of the rib. A comparison of OPD at sampling locations revealed significant differences, suggesting that sampling site is critical to accurate age estimates. When sampling location is uncertain, a more anterior section should be taken. Analysis of serial sections within locations revealed no significant differences in OPD or Ct.Ar, supporting the practice of collecting data from one section for age estimation. While an age estimate can be achieved through the analysis of one section, best practice suggests reading two sections to capture intraindividual variation.
Nemo‐age: Spatially explicit simulations of eco‐evolutionary dynamics in stage‐structured populations under changing environments
Authors: Cotto Olivier , Schmid Max , Guillaume Frédéric 
Published: August 2020

Abstract

Anticipating and preparing for the effect of environmental changes on biodiversity requires to understand and predict both the ecological and evolutionary responses of populations. Tools and methods to efficiently integrate these complex processes are lacking.

We present the genetically and spatially explicit individual‐based simulation software Nemo‐age combining ecological and evolutionary processes. Nemo‐age has a strong emphasis on modelling complex life histories. We here provide a methodology to predict changes in species distribution for given climate projections using Nemo‐age.

Modelling complex life histories, spatial distribution and evolutionary processes unravel possible eco‐evolutionary mechanisms that have been previously overlooked when populations endure rapid environmental changes.

The interface of Nemo‐age is designed to integrate species' data from different fields, from demography to genetic architecture and spatial distributions, thus representing a versatile tool to model a variety of applied and theoretical scenarios.

AbstractHow complex interactions of genetic, environmental factors and aging jointly contribute to dopaminergic degeneration in Parkinson's disease (PD) is largely unclear. Here, we applied frequent gene co‐expression analysis on human patient substantia nigra‐specific microarray datasets to identify potential novel disease‐related genes. In vivo Drosophila studies validated two of 32 candidate genes, a chromatin‐remodeling factor SMARCA4 and a biliverdin reductase BLVRA. Inhibition of SMARCA4 was able to prevent aging‐dependent dopaminergic degeneration not only caused by overexpression of BLVRA but also in four most common Drosophila PD models. Furthermore, down‐regulation of SMARCA4 specifically in the dopaminergic neurons prevented shortening of life span caused by α‐synuclein and LRRK2. Mechanistically, aberrant SMARCA4 and BLVRA converged on elevated ERK‐ETS activity, attenuation of which by either genetic or pharmacological manipulation effectively suppressed dopaminergic degeneration in Drosophila in vivo. Down‐regulation of SMARCA4 or drug inhibition of MEK/ERK also mitigated mitochondrial defects in PINK1 (a PD‐associated gene)‐deficient human cells. Our findings underscore the important role of epigenetic regulators and implicate a common signaling axis for therapeutic intervention in normal aging and a broad range of age‐related disorders including PD.

AbstractSubstance use disorder is a complex disease created in part by maladaptive learning and memory mechanisms following repeated drug use. Exposure to drug‐associated stimuli engages prefrontal cortex circuits, and dysfunction of the medial prefrontal cortex (mPFC) is thought to underlie drug‐seeking behaviors. Growing evidence supports a role for parvalbumin containing fast‐spiking interneurons (FSI) in modulating prefrontal cortical microcircuit activity by influencing the balance of excitation and inhibition, which can influence learning and memory processes. Most parvalbumin FSIs within layer V of the prelimbic mPFC are surrounded by specialized extracellular matrix structures called perineuronal nets (PNN). Previous work by our group found that cocaine exposure altered PNN‐surrounded FSI function, and pharmacological removal of PNNs reduced cocaine‐seeking behavior. However, the role of FSIs and associated constituents (parvalbumin and PNNs) in cocaine‐related memories was not previously explored and is still unknown. Here, we found that reactivation of a cocaine conditioned place preference memory produced changes in cortical PNN‐surrounded parvalbumin FSIs, including decreased parvalbumin intensity, increased parvalbumin cell axis diameter, decreased intrinsic excitability, and increased excitatory synaptic input. Further investigation of intrinsic properties revealed changes in the interspike interval, membrane capacitance, and afterhyperpolarization recovery time. Changes in these specific properties suggest an increase in potassium‐mediated currents, which was validated with additional electrophysiological analysis. Collectively, our results indicate that cocaine memory reactivation induces functional adaptations in PNN‐surrounded parvalbumin neurons, which likely alters cortical output to promote cocaine‐seeking behavior.

Published: August 2020

AbstractObjectivesTo evaluate outcomes associated with pharmacist‐led medication reviews in residential aged care facility (RACF) residents with dementia.MethodsSix scientific databases were searched. All study designs investigating pharmacist‐led medication reviews in RACF residents with dementia were considered. The protocol was registered with PROSPERO (CRD42019121681).ResultsOne randomised controlled trial (RCT) and five observational studies were identified. Two studies reported reductions in medication usage per resident, and one study reported improved appropriateness of psychotropic use following reviews as part of multi‐faceted, collaborative interventions. In three studies, reviews undertaken as an isolated intervention or by a visiting pharmacist with minimal collaboration with physicians were associated with low implementation rates of recommendations to alter therapy.ConclusionPharmacist‐led medication reviews, when conducted collaboratively, may improve the use of medicines in RACF residents with dementia. However, robust conclusions cannot be drawn, largely due to the low quality of evidence available, including only one RCT.

AbstractPurposeTo evaluate the clinical features, diagnostic challenges, management, and prognosis of sebaceous carcinoma (SC) of the eyelids and periocular region in a Nordic country.MethodsPatients were identified from the Finnish Cancer Registry and the Helsinki University Hospital databases during the 21‐year period 1998–2018. Age, sex, location, clinical and histopathologic diagnosis, treatment and outcome were registered.ResultsSebaceous carcinoma (SC) was diagnosed in 32 patients. The incidence was 0.6 per million. Median age at the time of histopathologic diagnosis was 74 years, and 72% of patients were women. Diagnostic delay was often long, median 12 months. The most common cause for delay was misdiagnosis (72%): a chalazion in 34% and a benign tumour in 22%. The most common location was the upper eyelid (53%) and tumour type a solitary nodule (94%). The SC was not correctly diagnosed in 12 (40%) of 30 preoperative biopsies. The treatment for 31 (97%) patients was complete surgical removal with reconstruction. Conjunctival intraepithelial growth was found in 50%. The leading postoperative problem was ocular irritation (30%). During a median follow‐up of 58 months, two patients (6%) experienced a local recurrence and one patient died from metastatic SC.ConclusionsThe estimated incidence of SC in Finland was somewhat higher than in other Western countries. The diagnosis was often markedly delayed. Especially differentiation from chalazion continues to be essential. To improve outcomes, it is essential to inform the pathologist about the possibility of SC in eyelid biopsies and specimens and ideally submit them to an ophthalmic pathology service.
