Short-term load forecasting for microgrids based on DA-SVM
Authors: Zhang Anan , Zhang Pengxiang , Feng Yating 
Published: September 2018

Purpose
The study aims to accomplish the short-term load forecasting for microgrids. Short-term load forecasting is a vital component of economic dispatch in microgrids, and the forecasting error directly affects the economic efficiency of operation. To some extent, short-term load forecasting is more difficult in microgrids than in macrogrids.

Design/methodology/approach
This paper presents the method of Dragonfly Algorithm-based support vector machine (DA-SVM) to forecast the short-term load in microgrids. This method adopts the combination of penalty factor C and kernel parameters of SVM which needs to be optimized as the position of dragonfly to find the solution. It takes the forecast accuracy calculated by SVM as the current fitness value of dragonfly and the optimal position of dragonfly obtained through iteration is considered as the optimal combination of parameters C and s of SVM.

Findings
DA-SVM algorithm was used to do short-term load forecast in the microgrid of an offshore oilfield group in the Bohai Sea, China and the forecasting results were compared with those of PSO-SVM, GA-SVM and BP neural network models. The experimental results indicate that the DA-SVM algorithm has better global searching ability. In the case of study, the root mean square errors of DA-SVA are about 1.5 per cent and its computation time is saved about 50 per cent.

Originality/value
The DA-SVM model presented in this paper provides an efficient and effective method of short-term load forecasting for a microgrid electric power system.

Published: September 2018

PurposeThis paper is a part of the application trend of the development of the grey systems theory. The purpose of this paper is to present the use of the GDM model in the diagnosis of the occurrence of crises in family businesses. The issue of the occurrence of conflicts and crises in family businesses is one of the most important and common in management science in Poland.Design/methodology/approachIn the paper using the GDM model (in which the weights of the criteria were determined using the modified Thurstone method), the authors presented a way to diagnose the occurrence of crises in family businesses for a sample of Polish family businesses using, among others, a questionnaire-based survey.FindingsAs a result of the conducted research, it turned out that in eight surveyed businesses no symptoms of conflicts were diagnosed. In three businesses, the symptoms of conflicts were diagnosed, but they did not threaten their existence. In the case of four businesses, the symptoms of crisis that threaten their existence were diagnosed and immediate remedial action was recommended to them.Originality/valueThe authors are of the opinion that the presented research results may be a reason for the validity of using the GDM model in the diagnosis of crises in family businesses. At the same time, it is recommended to undertake further research on,inter alia, conflict fields in family businesses, or on the use of the modified Thurstone method as a part of determining the validity of decision-making criteria in GDM models.
Using stage theorizing to make anti-phishing recommendations more effective
Authors: Tambe Ebot Alain 
Published: September 2018

Purpose
This paper aims to review the behavioral phishing literature to understand why anti-phishing recommendations are not very effective and to propose ways of making the recommendations more effective. The paper also examines how the concept of stages from health communication and psychology can be used to make recommendations against phishing more effective.

Design/methodology/approach
This literature review study focused on the behavioral phishing literature that has relied on human subjects. Studies were excluded for reasons that included lacking practical recommendations and human subjects.

Findings
The study finds that phishing research does not consider where victims are residing in qualitatively different stages. Consequently, the recommendations do not often match the specific needs of different victims. This study proposes a prototype for developing stage theories of phishing victims and identifies three stages of phishing victims from analyzing the previous phishing research.

Research limitations/implications
This study relied on published research on phishing victims. Future research can overcome this problem by interviewing phishing victims. Further, the authors’ recommendation that phishing researchers categorize phishing victims into stages and develop targeted messages is not based on direct empirical evidence. Nonetheless, evidence from cancer research and health psychology suggests that targeted messaging is efficacious and cost-effective. Thus, the impact of targeted messaging in phishing could be quite large.

Practical implications
The study recommends categorizing individuals into stages, based on their security knowledge and online behaviors, and other similar characteristics they may possess. A stage approach will consider that individuals who at one time clicked on a phishing link because they lacked the requisite security knowledge, after receiving security training, may click on a link because they are overconfident.

Originality/value
The paper explains why proposing anti-phishing recommendations, based on a “one-size fits all” approach has not been very effective (e.g. because it simplifies why people engage in different behaviors). The proposals introduce a new approach to designing and deploying anti-phishing recommendations based on the concept of stages.
Establishing information security policy compliance culture in organizations
Authors: Amankwa Eric , Loock Marianne , Kritzinger Elmarie 
Published: September 2018

PurposeThis paper aims to establish that employees’ non-compliance with information security policy (ISP) could be addressed by nurturing ISP compliance culture through the promotion of factors such as supportive organizational culture, end-user involvement and compliance leadership to influence employees’ attitudes and behaviour intentions towards ISP in organizations. This paper also aims to develop a testable research model that might be useful for future researchers in predicting employees’ behavioural intentions.Design/methodology/approachIn view of the study’s aim, a research model to show how three key constructs can influence the attitudes and behaviours of employees towards the establishment of security policy compliance culture (ISPCC) was developed and validated in an empirical field survey.FindingsThe study found that factors such as supportive organizational culture and end-user involvement significantly influenced employees’ attitudes towards compliance with ISP. However, leadership showed the weakest influence on attitudes towards compliance. The overall results showed that employees’ attitudes and behavioural intentions towards ISP compliance together influenced the establishment of ISPCC for ISP compliance in organizations.Practical implicationsOrganizations should influence employees’ attitudes towards compliance with ISP by providing effective ISP leadership, encouraging end-user involvement during the draft and update of ISP and nurturing a culture that is conducive for ISP compliance.Originality/valueThe study provides some insights on how to effectively address the problem of non-compliance with ISP in organizations through the establishment of ISPCC, which has not been considered in any past research.
Unemployment invariance hypothesis, added and discouraged worker effects in Canada
Authors: Tansel Aysit , Ozdemir Zeynel Abidin 
Published: September 2018

Purpose
The purpose of this paper is to explore the long-run relationship between unemployment rate (UR) and labor force participation rate (LFPR) for men and women in Canada. Given that there are differences in the URs and participation rates of men and women, the authors perform separate analysis for them also.

Design/methodology/approach
The authors use co-integration analysis to investigate the existence of a long-run relationship between UR and LFPR in Canada using time series monthly data for the past 40 years.

Findings
The finding that there is long-run relationship between UR and LFPR leads the authors to doubt the pertinence of the unemployment invariance hypothesis for Canada. The authors further find evidence for added-worker effect for men and discouraged-worker effect for women in Canada and the authors elaborate on the possible explanations for this seemingly contradictory finding.

Practical implications
The lack of support for the unemployment invariance hypotheses implies that changes in the participation rate which may be due to aging population, policies of early retirement or constraints on working time will affect the UR in the long run.

Originality/value
This paper investigates the unemployment invariance hypothesis in Canada to come up with policy implications about long-run UR. The authors further elaborate on the possible explanations for the added-worker effect for men and the discouraged-worker effect for women that the authors find in this study.
Chinese online public opinions on the Two-Child Policy
Authors: Wang Shixiong , Song Yu 
Published: September 2018

Purpose
The purpose of this paper is to use Weibo as a window to examine the Chinese netizens’ online attitudes and responses to two sets of population policy: the Selective Two-Child Policy (Phase 2) and the Universal Two-Child Policy. The population policy change from the rigid One-Child Policy to the Selective Two-Child Policy then to the Universal Two-Child Policy aroused great attention of the Chinese people.

Design/methodology/approach
This research uses the crawler technique to extract data on the Sina Weibo platform. Through opinion mining of Weibo posts on two sets of population policy, the Weibo users’ online opinions on the Two-Child Policy are analyzed from two perspectives: their attention intensity and sentiment tendency. The research also use the State Bureau of Statistics of China’s national population data between 2011 and 2016 to examine the Chinese people’s actual birth behaviors after implementing the two different sets of the Two-Child Policy.

Findings
The research findings indicate that the Selective Two-Child Policy (Phase 2) and the Universal Two-Child Policy are good examples of thematic public sphere of Weibo. Weibo posts on the two sets of the Two-Child Policy have undergone different opinion cycles. People from economically developed regions and populous regions have paid more attention to both sets of Two-Child Policy than their counterparts in the less developed and less populated regions. Men pay more attention to the Two-Child Policy than women do. Despite people’s huge attention to the new population policy, the population growth after the policy is not sustainable.

Research limitations/implications
The new population policy alone is difficult to boost China’s population within a short period of time. The Chinese Government must provide its people with enough incentives and supporting welfare to make the population growth happen.

Originality/value
These findings have important implications for understanding the dynamics of online opinion formation and changing population policy in China.
Peripheral apelin mediates stress‐induced alterations in gastrointestinal motor functions depending on the nutritional status

Published: September 2018

SummaryExposure to stress induces gastrointestinal (GI) dysmotility. In rodents, acute restraint stress (ARS) inhibits gastric emptying (GE) and intestinal transit (IT) via central and peripheral corticotropin‐releasing factor (CRF)‐mediated pathways. Peripherally administered apelin‐13 was shown to inhibit GI motor functions; moreover, stress‐induced upregulation of gastric apelin content was demonstrated in rats suggesting that peripheral apelin may mediate stress‐induced alterations in GI motility. We investigated the role of endogenous peripheral apelin in stress‐induced GI dysfunction. GE, IT and gastro‐duodenal fasting motility were measured in non‐stressed (NS), CRF‐injected and ARS‐loaded rats. CRF and apelin receptor antagonists astressin or F13A was administered before ARS or peripheral CRF injection. Apelin and APJ receptor expressions were determined using immunohistochemistry and quantified by qRT‐PCR. Double immunofluorescence was performed for enteric neuronal apelin. GE and IT were delayed by CRF and ARS. ARS‐induced changes were attenuated by F13A, whereas astressin was ineffective. CRF‐induced alterations in GE and IT were restored completely by astressin, while they were diminished by F13A. Antral phase III‐like contractions were disturbed following ARS which were preserved by preadministration of astressin, but not F13A. CRF impaired gastric and duodenal fasting contractions, while these changes were not altered by F13A. ARS increased apelin expression in stomach and duodenum. Apelin immunoreactivity was detected in mucosa, smooth muscles and myenteric plexi, whereas dense APJ receptor expression was observed within tunica muscularis. APJ receptor was downregulated in rats fasted overnight. These results suggest that enteric apelin acts as an inhibitor stress mediator in the postprandial state.

Published: September 2018

AbstractMaintenance hemodialysis (HD) patients often experience fluctuations of volume status. Although hypervolemia possibly induces systemic inflammation, the relationship between volume status and leptin has not yet been well defined. The aims of this study were to determine the levels of leptin, C‐reactive protein (CRP), and ferritin in relation to volume status and to assess the relationship between leptin and volume and inflammatory status in chronic HD patients. This prospective study included 93 HD patients divided, based on evaluation using the body composition monitor, into normovolemic and hypervolemic groups (overhydration/extracellular water [OH/ECW] ≤ 15% and OH/ECW > 15%, respectively). The levels of leptin and inflammatory markers (CRP, ferritin) were determined during a mid‐week dialysis session in all patients. There were more hypervolemic patients after 12 months of follow up than at baseline (41% vs. 38%). Hypervolemic patients had significantly lower leptin levels (11.42 ± 19.24 ng/mL vs. 34.53 ± 40.32 ng/mL at baseline and 13.41 ± 22.04 ng/mL vs. 41.54 ± 21.78 ng/mL at 12 months), longer time on dialysis, and poorer nutritional status than normovolemic patients. Inflammation was present regardless of the volume status, but hypervolemic patients had significantly higher CRP and ferritin than normovolemic patients. A statistically significant reverse correlation was found between leptin level, hyperhydration index, and OH/ECW. No significant correlation was found between leptin and inflammatory markers CRP and ferritin.

Published: September 2018

AbstractThe application of high‐throughput sequencing (HTS) for metabarcoding of mixed samples offers new opportunities in conservation biology. Recently, the successful detection of prey DNA from the guts of leeches has raised the possibility that these, and other blood‐feeding invertebrates, might serve as useful samplers of mammals. Yet little is known about whether sympatric leech species differ in their feeding preferences, and whether this has a bearing on their relative suitability for monitoring local mammalian diversity. To address these questions, we collected spatially matched samples of two congeneric leech species Haemadipsa picta and Haemadipsa sumatrana from lowland rainforest in Borneo. For each species, we pooled ~500 leeches into batches of 10 individuals, performed PCR to target a section of the mammalian 16S rRNA locus and undertook sequencing of amplicon libraries using an Illumina MiSeq. In total, we identified sequences from 14 mammalian genera, spanning nine families and five orders. We found greater numbers of detections, and higher diversity of OTUs, in H. picta compared with H. sumatrana, with rodents only present in the former leech species. However, comparison of samples from across the landscape revealed no significant difference in mammal community composition between the leech species. We therefore suggest that H. picta is the more suitable iDNA sampler in this degraded Bornean forest. We conclude that the choice of invertebrate sampler can influence the detectability of different mammal groups and that this should be accounted for when designing iDNA studies.
A late pre‐Islamic bowl with Levantine‐inspired decoration from ed‐Dur (UAE)
Authors: Overlaet Bruno , Yule Paul Alan 
Published: September 2018

AbstractAround 1977 the British engineer Peter Hudson found a corroded copper alloy bowl during a walk c.100–150 m south‐east of the ed‐Dur fort in Umm al‐Qaiwain. Ed‐Dur is one of the largest and most extensively explored sites along the UAE Gulf coast. Its main occupation dates from the late first century BCE to the early second century CE (PIR, Période préislamique récente, C). After cleaning, the bowl showed profuse engraved and repoussé decoration. It is compared with Levantine bowls from Nimrud, with several unprovenanced “South Arabian” bowls and with excavated bowls from the UAE and Oman. Although the bowl’s iconography copies familiar themes from Early Iron Age Levantine bowls, the data suggest a much later, local production. The bowl is attributed to the late pre‐Islamic period (PIR), phases A to C (third century BCE–early second century CE).
The dopamine transporter VNTR polymorphism moderates the relationship between acute response to alcohol and future alcohol use disorder symptoms

Published: September 2018

AbstractAlcohol use disorder (AUD) is a genetically influenced disease with peak onset in young adulthood. Identification of factors that predict whether AUD symptoms will diminish or persist after young adulthood is a critical public health need. King and colleagues previously reported that acute response to alcohol predicted future AUD symptom trajectory. Genes associated with brain dopamine signaling, which underlies alcohol's rewarding effects, might influence this finding. This study analyzed whether variation at a variable number tandem repeat polymorphism in DAT1/SLC6A3, the gene encoding the dopamine transporter, moderated the predictive relationships between acute response to alcohol and future AUD symptoms among participants enrolled in the Chicago Social Drinking Project (first two cohorts). Heavy‐drinking young adults (N = 197) completed an alcohol challenge, in which acute response (liking, wanting, stimulation, and sedation) was measured. Alcohol use disorder symptoms were assessed over the following 6 years. DAT1 genotype significantly moderated the interactions between follow‐up time and alcohol liking (P = 0.006) and wanting (P = 0.006) in predicting future AUD symptoms. These predictive effects were strongest among participants who carried the DAT1 9‐repeat allele, previously associated with enhanced striatal dopamine tone relative to the 10‐repeat allele. Exploratory analyses indicated that DAT1 effects on the relationship between alcohol liking and AUD symptoms appeared stronger for females (n = 79) than males (n = 118) (P = 0.0496). These data suggest that heavy‐drinking DAT1 9‐repeat allele carriers who display high alcohol‐induced reward in young adulthood may be predisposed to persistent AUD symptoms and support combining genotypic and phenotypic information to predict future AUD risk.

AbstractAlthough the involvement of dopamine in gambling disorder (GD) has long been hypothesized, its precise role remains unclear. The action of dopamine in the synapses is regulated by the dopamine transporter (DAT). We hereinafter present significant differences between a sample of 15 treatment‐seeking GD subjects and 17 healthy controls in terms of striatal DAT availability, and we explore its association with reward‐based decision making. We performed 123I‐FP‐CIT Single‐photon emission computed tomography (SPECT) and correlated DAT binding ratios in the bilateral caudate and putamen with gambling symptoms (G‐SAS, PG‐YBOCS) and behaviors, as well as other psychometric variables (anhedonia and impulsivity). Gambling disorder (GD) subjects were also administered a computerized version of the Iowa gambling task (IGT) to assess reward‐based decision making. We found reduced DAT availability in GD subjects compared with healthy controls (−13.30% in right caudate, −11.11% in right putamen, −11.44% in left caudate, and −11.46% in the left putamen). We also found that striatal DAT availability was inversely correlated with days spent gambling and IGT performance in GD subjects. These results provide evidence for a presynaptic dopaminergic dysfunction in striatal regions of GD subjects. Functional DAT down‐regulation possibly sustains the transition towards compulsive gambling addiction, characterized both by hyperdopaminergic and hypodopaminergic states in the context of a sensitized dopaminergic system.

AbstractBackgroundThere are limited data on the feasibility, efficacy and safety of high‐dose oral immunotherapy (OIT) in children highly allergic to peanuts.ObjectiveIn children highly allergic to peanut, we primarily aimed to determine the feasibility of reaching the maximum maintenance dose (MMD) of 5000 mg peanut protein or, alternatively, a lower individual maintenance dose (IMD), by OIT up‐dosing. Secondarily, we aimed to identify adverse events (AEs) and determine factors associated with reaching a maintenance dose.MethodsThe TAKE‐AWAY peanut OIT trial enrolled 77 children 5‐15 years old, with a positive oral peanut challenge. Fifty‐seven were randomized to OIT with biweekly dose step‐up until reaching MMD or IMD and 20 to observation only. Demographic and biological characteristics, AEs, medication and protocol deviations were explored for associations with reaching maintenance dose.ResultsAll children had anaphylaxis defined by objective symptoms in minimum two organ systems during baseline challenge. The MMD was reached by 21.1%, while 54.4% reached an IMD of median (minimum, maximum) 2700 (250, 4000) mg peanut protein, whereas 24.5% discontinued OIT. During up‐dosing, 19.4% experienced anaphylaxis. Not reaching the MMD was caused by distaste for peanuts (66.7%), unacceptable AEs (26.7%) and social reasons (6.7%). Increased peanut s‐IgG4/s‐IgE ratio (OR [95% CI]: 1.02 [1.00, 1.04]) was associated with reaching MMD.ConclusionAlthough 75.5% of children with peanut anaphylaxis reached a maintenance dose of 0.25‐5 g, only 21.1% reached the MMD. Distaste for peanuts and AEs, including high risk of anaphylaxis, limited the feasibility of reaching MMD.
