An IoT-based risk warning system for smart libraries
Authors: Xie Yi , Liu Jia , Zhu Shufan , Chong Dazhi , Shi Hui , Chen Yong 
Published: July 2019

Purpose
When integrating smart elements offered by emergent technologies, libraries are facing the challenges of technological renovation and maintaining their operation using emerging technology. Given the importance of smart library, new technologies are needed in building new libraries or renovation of existing libraries. The purpose of this paper is to propose a risk warning system for library construction or renovation in the aspect of risk management.

Design/methodology/approach
The proposed Internet of Things (IoT)-based system consists of sensors that automatically monitor the status of materials, equipment and construction activities in real time. AI techniques including case-based reasoning and fuzzy sets are applied.

Findings
The proposed system can easily track material flow and visualize construction processes. The experiment shows that the proposed system can effectively detect, monitor and manage risks in construction projects including library construction.

Originality/value
Compared with existing risk warning systems, the proposed IoT-based system requires less data for making dynamic predictions. The proposed system can be applied to new builds and renovation of libraries.
Consumers’ CSR boycott: the mediating role of psychological contract violation
Authors: Deng Xinming , Long Xianyi 
Published: July 2019

Purpose
Consumers may boycott firms’ corporate social responsibility (CSR) activities, but little is known about when, why and how they would respond in this way. Based on psychological contract violation and discount principles, the purpose of this paper is to argue that timing and fit of CSR activities are the main dimensions of consumers’ psychological contract. It is posited that CSR activities would be boycotted if consumers perceived violation of their psychological contract, and their altruistic tendency would have a moderating effect on this mechanism.

Design/methodology/approach
This paper takes the form of an empirical study using a sample of 434 respondents through scene-questionnaire survey in central China.

Findings
It is found that (1) low fit or reactive CSR activities would induce consumers’ psychological contract violation, and the latter has a more significant influence; (2) perceived CSR is negatively related with consumers’ boycott behaviors, but CSR activities would be boycotted if consumers’ psychological contracts are violated; (3) the negative relationship between perceived CSR and consumers’ boycott behaviors would be strengthened by consumers’ altruistic tendency, and the positive relationship between consumers’ psychological contract violation and their boycott behaviors would also be strengthened by their altruistic tendency.

Research limitations/implications
This paper has significant theoretical implications, as it answers the question that when, why and how CSR activities would be boycotted. Besides, it contributes to literature on psychological contract for applying it to CSR research field. Furthermore, the double-edged effect of consumers’ altruistic tendency extends literature on pro-social behaviors.

Social implications
This paper is of interests to corporate management and academics who wish to understand when and why consumers would boycott CSR activities and the factors that would relax consumers’ negative responses.

Originality/value
This is the first paper that investigates when, why and how CSR activities would be boycotted from the perspective of consumers’ psychological contract violation.
Loneliness in later life: a cross-sectional survey analysis of place-based factors in Ireland
Authors: Gibney Sarah , Moore Tara , Shannon Sinead 
Published: July 2019

Purpose
The purpose of this paper is to investigate the relationship between the age-friendliness of local environments and self-reported loneliness for a representative sample of community-dwelling adults aged 55+ in Ireland.

Design/methodology/approach
Data were from the Healthy and Positive Ageing Initiative Age friendly Cities and Counties Survey (n=10,540) (2016). Several age friendly indicators, as proposed by World Health Organisation, were included in this study: outdoor spaces and buildings; access to social services; social participation; respect and social inclusion; and transport. Loneliness was measured using five items from the UCLA Loneliness Scale. Informed by an ecological approach to ageing, multi-level negative binomial regression models were used to investigate the association between each age friendly indicator and social loneliness. Models were adjusted for known demographic, socio-economic and health correlates of loneliness.

Findings
Average loneliness scores were significantly higher for those in poorer health, who lived alone, were materially deprived and those never or formerly married. Lower ratings and poorer outcomes for several interrelated age friendly place-based factors were significantly associated with higher loneliness scores: difficulty with transport, difficulty accessing social services, barriers to community activities, lower social engagement, and experiences and perceptions of ageism in the community; however, the effect sizes were small.

Originality/value
This study identified several modifiable age friendly features of local environments that are associated with loneliness in this older population. The results of this study can inform coordinated local and national efforts to enhance the age-friendliness of local environments and reduce the risk and experience of loneliness among the ageing population in Ireland.
Does corporate social responsibility lead to improved firm performance? The hidden role of financial slack
Authors: Lin Woon Leong , Ho Jo Ann , Ng Siew Imm , Lee Chin 
Published: July 2019

PurposeThe purpose of this study is to investigate the relationship between corporate social responsibility (CSR) and corporate financial performance (CFP), as the findings on the relationship have been inconsistent and have led to calls to further examine this relationship. However, instead of investigating the connection between CSR and CFP, academics have stated that a contingency viewpoint must be used for uncovering the context and conditions which catalyse the relationship between both constructs.Design/methodology/approachThis study acquired the CSR data from 100 companies listed in Fortune’s most admired US companies between 2007 and 2016. These data were used to investigate the CSR–CFP link with the help of the dynamic panel data system, which is the generalised method of moments (GMM) estimator.FindingsThe results indicate that CSR and CFP have a neutral relationship which characterises the effect between CFP and CSR. However, this study found that financial slack positively affected the CSR–CFP relationship, implying that companies will only benefit from CSR activities if they have excess financial resources.Originality/valueThis study offers a very distinctive perspective regarding the CSR–CFP link according to the financial slack perspective.
Filifactor alocis and Dialister pneumosintes in a Mexican population affected by periodontitis and rheumatoid arthritis: An exploratory study
Authors: Ayala Herrera José Luis , Apreza Patrón Luis , Martínez Martínez Rita Elizabeth , Domínguez Pérez Rubén Abraham , Abud Mendoza Carlos , Hernández Castro Berenice 
Published: July 2019

AbstractFilifactor alocis and Dialister pneumosintes have been associated with the initiation and progression of periodontitis (PE). We determined and compared the frequency of both bacteria in patients with PE, rheumatoid arthritis (RA), and PE/RA simultaneously. Detection was performed by polymerase chain reaction in the subgingival biofilm. Bacteria were more frequent in patients with PE, and clinical periodontal parameters such as pocket depth (PD) and clinical attachment loss (CAL) were significantly higher in patients with PE/RA. F. alocis and D. pneumosintes could influence PD and CAL, hence participating in the initiation and progression of PE in patients with RA.
The attenuated Ricker wavelet basis for seismic trace decomposition and attenuation analysis
Authors: Zhang Xuebing , Liu Cai , Feng Xuan , Li Bonan , Li Kexin , You Qin 
Published: July 2019

ABSTRACTThe widely used wavelets in the context of the matching pursuit are mostly focused on the time–frequency attributes of seismic traces. We propose a new type of wavelet basis based on the classic Ricker wavelet, where the quality factor Q is introduced. We develop a new scheme for seismic trace decomposition by applying the multi‐channel orthogonal matching pursuit based on the proposed wavelet basis. Compared with the decomposition by the Ricker wavelets, the proposed method could use fewer wavelets to represent the seismic signal with fewer iterations. Besides, the quality factor of the subsurface media could be extracted from the decomposition results, and the seismic attenuation could be compensated expediently. We test the availability of the proposed methods on both synthetic seismic record and field post‐stack data.

Published: July 2019

AbstractUnopened flower buds of Capparis spinosa L. (capers), generally used in the Mediterranean area as food flavoring, are known to be a good source of bioactive compounds. The aim of this work was to evaluate the nutraceutical value of salt‐fermented capers collected from different areas of Pantelleria Island (Italy), testing their methylglyoxal and glyoxal trapping capacity and antioxidant activity by 2,2‐diphenyl‐1‐picryl hydrazyl (DPPH), [2,2‐azinobis(3‐ethylben‐ zothiazoline‐6‐sulfonic acid)] diammonium salt (ABTS), and oxygen radical absorbance capacity (ORAC) assays. Hydrophilic extracts were also characterized by high‐performance liquid chromatography–electrospray ionization/mass spectrometry. Among 24 detected compounds, several flavonol derivatives and glucosinolates were identified. The levels of kaempferol and quercetin derivatives varied considerably among the five accessions considered (6.46 to 267.93 and 22.39 to 367.14 mg kaempferol and quercetin equivalent /g fresh weight, respectively), with kaempferol derivatives more representative than quercetin ones. Person's coefficient indicated a high correlation between total phenolic content and anti‐DPPH radical capacity (R2 = 0.665), as well as between total flavonoid content and antioxidant capacity (by ORAC assay; R2 = 0.888) and between total flavonoid content and glyoxal and methylglyoxal trapping capacity (R2 = 0.918). Results indicate that capers from Pantelleria Island represent a rich source of bioactive compounds with potential nutraceutical relevance.Practical ApplicationThe findings of this study highlight the health benefits of Pantelleria capers consumption due to their composition in antioxidants and their biological properties (antiradical and alpha‐dicarbonyls trapping) correlated with the development of a high number of chronic–degenerative diseases. These results are also important for the agricultural and commercial sectors involved in the production of capers from Pantelleria, which received the Protected Geographical Indications recognition.
Competitive cross‐subsidization
Authors: Chen Zhijun , Rey Patrick 
Published: July 2019

AbstractCross‐subsidization arises naturally when firms with different comparative advantages compete for consumers with heterogeneous shopping patterns. Firms then face a form of co‐opetition, as they offer substitutes for one‐stop shoppers and complements for multi‐stop shoppers. When intense competition for one‐stop shoppers drives total prices down to cost, firms subsidize weak products with the profits made on strong products. Moreover, firms have incentives to seek comparative advantages on different products. Finally, banning below‐cost pricing increases firms' profits at the expense of one‐stop shoppers, which calls for a cautious use of below‐cost pricing regulations in competitive markets.
Corporate governance and family firm performance during the Global Financial Crisis
Authors: Aldamen Husam , Duncan Keith , Kelly Simone , McNamara Ray 
Published: July 2019

AbstractWe investigate the impact of corporate governance on accounting and market performance relationships of family firms during the Global Financial Crisis (GFC). We expect the monitoring aspects of corporate governance to complement the long‐term orientation of family firms, improving the value relevance of accounting and market performance during times of exogenous financial shocks such as the GFC. We find that the family‐firm value is more sensitive to book value than earnings changes. We also find better corporate governance, irrespective of whether it is a family firm or non‐family firm, is associated with better accounting and market performance during the GFC.
Interleukin‐22 secreted by ectopic endometrial stromal cells and natural killer cells promotes the recruitment of macrophages through promoting CCL2 secretion

Published: July 2019

AbstractProblemDuring endometriosis, there is an increase in the number of dysfunctional macrophages; however, the mechanisms underlying macrophage recruitment are not well understood. The aim of the present study was to determine the role of natural killer (NK) cell‐mediated secretion of chemokine (C‐C motif) ligand 2 (CCL2) from endometrial stromal cells (ESCs) in the recruitment of macrophages.Method of studyNormal ESCs (nESC) and ectopic ESCs (eESCs) were separately co‐cultured with NK cells for a macrophage chemotaxis assay, and the number of chemotactic macrophages was counted. The expression of interleukin‐22 (IL‐22) and IL‐22 receptors was detected by ELISA and flow cytometry, respectively. eESCs were treated with 0.01, 0.1, and 1 ng/mL recombinant human IL‐22 (rhIL‐22) to determine the most effective concentration for stimulating CCL2 production. Following treatment with 1 ng/mL rhIL‐22, secretion of CCL2 was detected from both the eESC monoculture and the eESC/NK co‐culture.ResultsCompared with the eESC monoculture, the eESC/NK co‐culture recruited a significantly higher number of chemotactic macrophages. There was also an increase in the levels of IL‐22 and CCL2 secreted when eESCs were co‐cultured compared with the monoculture. Treatment with rhIL‐22 resulted in an increase in the levels of CCL2 secreted by eESCs, and the IL‐22‐induced CCL2 secretion was reversed by the IL‐22 antagonist, αIL‐22. Increased expression of IL‐22 resulted in an increase in the number of chemotactic macrophages, but was reversed by αIL‐22 and CCL2 antagonist (αCCL2).ConclusionInterleukin‐22 and CCL2 secretion by eESCs stimulated by NK cells contributes to the induction of macrophage recruitment and is thus implicated in the development of endometriosis.
High birthweight was not associated with altered body composition or impaired glucose tolerance in adulthood
Authors: Johnsson Inger Wahlström , Ahlsson Fredrik , Gustafsson Jan 
Published: July 2019

AbstractAimTo investigate whether a high birthweight was associated with an increased proportion of body fat or with impaired glucose tolerance in adulthood.MethodsOur cohort comprised 27 subjects with birthweights of 4500 g or more, and 27 controls with birthweights within ±1 standard deviation scores, born at Uppsala University Hospital 1975‐1979. The subjects were 34‐40 years old at the time of study. Anthropometric data was collected, and data on body composition was obtained by air plethysmography and bioimpedance and was estimated with a three‐compartment model. Indirect calorimetry, blood sampling for fasting insulin and glucose as well as a 75 g oral glucose tolerance test were also performed. Insulin sensitivity was assessed using homoeostasis model assessment 2 and Matsuda index.ResultsThere were no differences in body mass index, body composition or insulin sensitivity between subjects with a high birthweight and controls.ConclusionIn this cohort of adult subjects, although limited in size, those born with a moderately high birthweight did not differ from those with birthweights within ±1 standard deviation scores, regarding body composition or glucose tolerance.
The Hand of God or the Work of the Devil? Spiritual Appraisals and Psychological Adjustment After the 2016 U.S. Presidential Election

Published: July 2019

AbstractTo what extent do people perceive the election of President Trump as the work of evil forces, a violation of the sacred, or the will of God? Demonization and desecration are negative spiritual appraisals associated with psychological maladjustment across political and relational contexts. Sanctification refers to the imbuing of persons, objects, or events with sacred qualities or as manifestations of a higher power. The authors examined the prevalence and role of spiritual appraisals related to the 2016 U.S. presidential election result on psychological adjustment and behaviors using a cross‐sectional online sample of 252 American voters. Approximately one‐fifth of participants sanctified the election of President Trump to some degree. Conversely, approximately one‐third of participants endorsed some level of negative spiritual appraisals. Desecration and demonization also uniquely predicted maladjustment. Moreover, the interactive effect between vote and negative spiritual appraisals accounted for unique variance in maladjustment. At higher levels of demonization and desecration, those who voted for President Trump reported greater difficulties with emotion regulation than those who voted against President Trump. Negative spiritual appraisals also moderated the relations between vote and thought suppression, in addition to vote and information seeking behavior. For the small fraction of Trump voters with negative spiritual appraisals, their efforts to suppress misgivings, struggle with emotions, and seek information may be understood as attempts to reduce cognitive dissonance.

Published: July 2019

AbstractIntramuscular fat (IMF) content has been identified as a crucial factor of porcine meat quality. MAT2A and MAT2B coordinately catalyzes the synthesis of the major biological methyl donor S‐adenosylmethionine (SAMe). However, the regulatory effect of MAT2A and MAT2B on porcine intramuscular preadipocyte proliferation has not been clarified. In this study, we investigated the effect of MAT2A and MAT2B and its potential mechanism during porcine intramuscular proliferation. We demonstrated that overexpression of MAT2A and MAT2B promoted the cell cycle progression of porcine preadipocyte by flow cytometry and EdU‐labeling assay, as well as promoted the expression of cell cycle marker genes including Cyclin B, Cyclin D, and Cyclin‐dependent kinase 4, but reduced the expression of cell cycle inhibitor P27. Consistently, knockdown of MAT2A and MAT2B inhibited cell cycle progression and downregulated the mRNA and protein levels of the above genes. Furthermore, overexpression of MAT2A and MAT2B activated the phosphorylation of ERK1/2. Moreover, the inhibitory effect of U0126 (a specific ERK1/2 inhibitor) on the ERK1/2 activities was partially recovered by overexpression of MAT2A and MAT2B in porcine intramuscular preadipocytes. Taken together, our findings suggested that MAT2A and MAT2B promote porcine preadipocyte proliferation by ERK1/2 signaling pathway.
Measuring preschool children's knowledge of the principle of static equilibrium in the context of building blocks: Validation of a test instrument
Authors: Weber Anke Maria , Leuchter Miriam 
Published: July 2019

BackgroundPreschoolers’ knowledge of the principle of static equilibrium is an important research focus for understanding children's science content knowledge. Hitherto studies have mainly used behavioural observation with small samples. Thus, extending these studies with a validated test instrument is desirable.AimsThe aim was to validate an instrument (the Centre‐of‐Mass Test), which is concerned with preschoolers’ knowledge of the principle of static equilibrium, using item response theory. In Study 1, the construct structure was tested, and in Study 2, its relationship with stabilities of symmetrical blocks, figural reasoning, figural perception, mental rotation, level of interest, self‐concept, motivation, and language capacity was investigated.SamplesA total of 217 five‐ and six‐year‐old children participated in Study 1 and 166 five‐ and six‐year‐old children in Study 2.MethodsAll tests were administered as paper–pencil picture tests in groups and single interviews.ResultsIn Study 1, the Centre‐of‐Mass Test's conformity with a 1PL‐testlet model with an overall knowledge of static equilibrium and with two subtests, estimation of stable and unstable constructions, was confirmed. Using a 95% binomial distribution, children were categorized into three knowledge categories: geometrical‐centre, centre‐of‐mass, and undifferentiated knowledge. In Study 2, knowledge of the principle of static equilibrium showed positive correlations with figural perception and reasoning, language capacity, and estimation of the stabilities of symmetrical objects.ConclusionsThe Centre‐of‐Mass Test measures knowledge of the principle of static equilibrium as a unidimensional construct and mirrors preschoolers’ estimations found in previous studies. The acquisition of a more sophisticated static equilibrium knowledge is related to spatial knowledge and language capacity.

AbstractEvery year, approximately 1.2 million cases of colorectal carcinoma (CRC) are newly diagnosed worldwide. Although metastases to distant organs are often fatal complications of CRC, little information is known as to how such metastatic lesions are formed. To reveal the genetic profiles for CRC metastasis, we conducted whole‐exome RNA sequencing on CRC tumors with liver metastasis (LM) (group A, n = 12) and clinical stage‐matched larger tumors without LM (group B, n = 16). While the somatic mutation profiles were similar among the primary tumors and LM lesions in group A and the tumors in group B, the A‐to‐C nucleotide change in the context of “AAG” was only enriched in the LM regions in group A, suggesting the presence of a DNA damage process specific to metastasis. Genes already known to be associated with CRC were mutated in all groups at a similar frequency, but we detected somatic nonsynonymous mutations in a total of 707 genes in the LM regions, but not in the tumors without LM. Signaling pathways linked to such “LM‐associated” genes were overrepresented for extracellular matrix‐receptor interaction or focal adhesion. Further, fusions of the ADAP1 (ArfGAP with dual PH domain 1) were newly identified in our cohort (3 out of 28 patients), which activated ARF6, an ADAP1‐substrate. Infrequently, mutated genes may play an important role in metastasis formation of CRC. Additionally, recurrent ADAP1 fusion genes were unexpectedly discovered. As these fusions activate small GTPase, further experiments are warranted to examine their contribution to CRC carcinogenesis.
