Authors: Sami Parinaz , Rahnavard Farajollah , Alavi Tabar Alireza 
Published: June 2019

PurposeThe purpose of this study is to investigate the mediator role of product innovation in the relationship between political and business ties (independent variables) and firm performance (dependent variable).Design/methodology/approachIn this study, research hypotheses were tested using the structural equation modeling method.FindingsThe findings from 267 manufacturing companies in Iran show that business ties have an effect on firm performance through product innovation, while the role of innovation is not proved as a mediating variable in the relationships between political ties and firm performance. In addition, business ties have an effect on product innovation and firm performance, whereas political ties have no such effect.Practical implicationsThese results provide useful points for developing economies, theoretically and practically.Originality/valueDespite the increasing attention to the role of managerial ties (political and business ties) in improving product innovation and firm performance, there is no study conducted on the mediating role of product innovation in the relationship between managerial ties and firm performance.

Authors: Moravejolahkami Amir Reza , Paknahad Zamzam , Chitsaz Ahmad 
Published: June 2019

PurposeDietary fiber and energy intakes seem to be related to disability and anthropometric indices in multiple sclerosis (MS), a chronic inflammatory disorder of the central nervous system. So, this study was designed to investigate the association between dietary fiber and energy intakes with systemic inflammation, disease severity and anthropometric measurements in MS subjects.Design/methodology/approachFour subtypes of 261 MS volunteers were recruited (female = 210, male = 51; mean age 38.9 ± 8.3). A 168-item food frequency questionnaire and nutritionist IV software were used to estimate the amounts of dietary, insoluble, soluble, crude fiber and energy intakes. Serum hs-CRP, extended disability status scale (EDSS), height, weight and Deurenberg equation were also used to evaluate systemic inflammation, disease severity, body mass index (BMI) and percentage body fat, respectively.FindingsMean differences among the three hs-CRP and EDSS subgroups for dietary fibers and energy intake were significant (p < 0.001). Dietary fiber intake (M = 19.9 ± 4.3 g/day) was a good predictor for EDSS (B = −0.196,p = 0.012), and insoluble fiber intake was introduced as the best predictor of hs-CRP (B = −3.293,p < 0.001). Energy intake predicted both BMI (B = 0.007,p < 0.001) and percentage body fat (B = 0.015,p < 0.001).Originality/valueHypocaloric and high prebiotic fiber diet may suppress systemic inflammation and thereby modulate disease severity, as well as control anthropometric indices.
China’s Guangdong-Hong Kong-Macao Greater Bay Area: a new development opportunity for Hong Kong
Authors: Lau Siu-kai 
Published: June 2019

Purpose
The Guangdong-Hong Kong-Macao Greater Bay Area (GBA) Strategy is an important component of the “Belt and Road Initiative” of China. The purpose of this Project is to develop the GBA into the most open, market-oriented and innovative pole of economic growth in China. The GBA Project provides Hong Kong with a rare opportunity to diversify its industrial structure and to move into a new and higher stage of economic development.

Design/methodology/approach
Being an integral part of the GBA, Hong Kong is expected and supported by the Central Government to develop into a hub of the Area, and, leveraging on Hong Kong’s status as an international metropolis, to connect the Area as a whole with the world.

Findings
China’s Guangdong-Hong Kong-Macao Greater Bay Area Project is a major national development strategy and is a major part of the Belt and Road Initiative. Hong Kong is going to play an important role in the Project and will benefit from it enormously in the future in terms of economic growth and the upgrading of its industrial structure. However, in order to take full advantage of participation in the Project, the way Hong Kong is governed, particularly the government's role in economic development, has to be modified significantly.

Originality/value
In order to take advantage of the Project, the Hong Kong SAR Government has to play a bigger and more proactive role in Hong Kong’s socioeconomic development and to strengthen its capacity to mobilize societal participation in the Project.
Earnings forecast revisions and securities prices evolution in the Tunisian stock market
Authors: Bouteska Ahmed , Regaieg Boutheina 
Published: June 2019

Purpose
The purpose of this paper is to investigate the effect of forecast earnings’ revision on the evolution of securities prices in the Tunisian stock market.

Design/methodology/approach
A portfolio study of investor reaction and stock prices following revisions is first conducted to highlight the existence of abnormal return related to analysts’ earnings revisions. Analysis is then supplemented by a second empirical investigation based on the panel data to quantify the effect of revision on the abnormal profitability of securities.

Findings
The evidence found in this paper validates the fundamental theoretical hypothesis according to which the psychological bias resulting from the effect of the forecast earnings revision is related to the abnormal profitability of the securities. The authors conclude the importance of the revision impact on investors’ behavior on one hand, and the informational content of the analysts’ forecasts and the biases which they lead on the other hand.

Originality/value
Globally, the empirical illustrations largely validate the findings of behavioral models particularly that of Kormendi and Lippe (1987), Cornell and Letsman (1989), Beaver et al. (2008) which states that investors under psychological bias, react to the effect of forecast earnings revision by an abnormal variation in stock prices.
Journal of Behavioral Finance in retrospect
Authors: Calma Angelito 
Published: June 2019

Purpose
The purpose of this paper is to examine the impact and contribution of the Journal of Behavioral Finance (JBF).

Design/methodology/approach
It uses the metadata from 328 journal articles (2004–2017) extracted from Scopus and Web of Science. The data included 2,602 author-submitted keywords, 1,825 index keywords and 310 abstracts.

Findings
Results indicate that JBF is still a young journal with 196 academic articles cited by 372 documents. Most citations come from JBF itself and the Journal of Behavioral and Experimental Finance. Mesly and Seiler are the most published, University of Gothenberg has more contributions than any other institution while the USA, Australia and UK represent nearly half of those citations. Investment policy is the most used author keyword next to behavioural finance, while risk is the most used index keyword. The most commonly used words in abstracts are investor or investors. The implications of and for JBF are discussed.

Originality/value
It is a unique and novel approach to analysing almost the entire publication history of the journal by using citation analysis.
The unspoken facets of buying by individual investors in Indian stock market
Authors: Bondia Ripsy , Biswal Pratap Chandra , Panda Abinash 
Published: June 2019

PurposeThe purpose of this paper is to develop an in-depth contextualized understanding of individual investors’ buying decision in Indian stock market. Specifically, it provides answers to: how do individual investors make buying decision in stock market; and how and when do biases set in during such decisions. The paper also brings forward some aspects of individual’s journey as an investor.Design/methodology/approachGiven the exploratory nature of this study, the paper takes a step away from typically used variance approach and instead uses a process approach. The authors do in-depth one-on-one interview, where each respondent shares his/her lived experiences as an investor retrospectively. To understand buying decision, each respondent is asked to elaborate three significant buying transactions carried out by him/ her in stock market.FindingsSocio-cultural factors are found to have significant influence in inducing respondents to enter market. “Safe” vs “Risky” mental account emerges as the prominent stock categorization done by Indian investors. Three building blocks, namely, Identification, Rationalization and Further Validation emerge as the building blocks that culminate into buying decision of individual investors. The biases are seen to play a dual role in such decisions; as Attention Boosters and Rationales.Originality/valueThis study, to the best of authors’ knowledge, is first of its kind which amalgamates behavioral biases with phenomenon such as attention and Rationalization, to understand “how” behavioral biases set in during buying decision of individual investors.
Relationship Among Coping Strategies, Quality of Life, and Anxiety and Depressive Disorders in Hemodialysis Patients
Authors: Işık Ulusoy Selen , Kal Öznur 
Published: June 2019

AbstractPatients with hemodialysis face many physical and emotional stressors; yet little is known regarding coping strategies and their effects on patients' quality of life (QOL) and anxiety and depressive disorders. A total of 117 patients were enrolled in this cross‐sectional study between October 2016 and April 2017. This study assessed QOL (Medical outcome short form 36—MOS 36), coping (Assessment Scale for Coping Attitudes—COPE) and psychiatric comorbidities in hemodialysis patients. Beck Depression Scale and Beck Anxiety Scale were also applied. Differences between groups were evaluated using Student's t‐tests and anova. Correlations among parameters were performed. Patients with any depressive disorder (22.2%, n = 26) and patients with any anxiety disorder (19.6%, n = 23) reported more impaired QOL. The most frequently used coping strategy in all patients was religious coping. Use of instrumental social support, humor, and positive reinterpretation scores were lower in patients with any depressive disorder (P = 0.009, P = 0.034, P = 0.047).The total score of emotion‐focused coping strategies was lower with patients with any depressive disorder (P = 0.021) and emotion‐focused coping strategies were positively correlated with QOL scores. Younger age and longer duration of hemodialysis have significant negative correlation with emotion‐focused coping strategies' total score (P = 0.01, P = 0.02). Patients with hemodialysis use variety of coping strategies. The use of emotion‐focused coping was associated with better QOL and reducing the risk of depressive disorder. Interventions to facilitate the use of adaptive coping strategies may improve patients' QOL and mood.
Deciding on Appropriate Use of Force: Human‐machine Interaction in Weapons Systems and Emerging Norms
Authors: Huelss Hendrik 
Published: June 2019

AbstractThis article considers the role of norms in the debate on autonomous weapons systems (AWS). It argues that the academic and political discussion is largely dominated by considerations of how AWS relate to norms institutionalised in international law. While this debate on AWS has produced insights on legal and ethical norms and sounded options of a possible regulation or ban, it neglects to investigate how complex human‐machine interactions in weapons systems can set standards of appropriate use of force, which are politically normatively relevant but take place outside of formal, deliberative law‐setting. While such procedural norms are already emerging in the practice of contemporary warfare, the increasing technological complexity of AI‐driven weapons will add to their political‐normative relevance. I argue that public deliberation about and political oversight and accountability of the use of force is at risk of being consumed and normalised by functional procedures and perceptions. This can have a profound impact on future of remote‐warfare and security policy.
Market response to syndicated loan announcements from high‐profile failed and acquiring banks during the global financial crisis
Authors: Gasbarro Dominic , Le Kim‐Song , Schwebach Robert G. , Zumwalt J. Kenton 
Published: June 2019

AbstractPrevious studies that have examined the impact of the 2008 financial crisis on syndicated loans have ignored potential differences between lending banks by explicitly or implicitly aggregating all lenders together and focusing on borrower characteristics. One must jointly consider both borrower and lender to fully understand the complex role of the syndicate during this period. We consider the identity of the lender, with a focus on five major US banks that failed and their five corresponding acquirers. Our results highlight the distinct roles of investment and commercial banks and facilitate an understanding of relationship and transactional‐based lending.

Published: June 2019

BackgroundExisting evidence indicates that social support may enhance recipients’ self‐efficacy (enabling hypothesis) or that self‐efficacy facilitates support receipt (cultivation hypothesis). However, less is known about the time‐lagged support–self‐efficacy relationship in couples. Our aim was to disentangle reciprocal interrelations among stable and time‐varying components of support provision and self‐efficacy in couples over time.MethodsWe conducted secondary analyses of a published randomised controlled trial with six assessments, spanning 1 year andN = 338 heterosexual couples (age range: 18–80 years). Women's and men's reports on physical activity‐specific provided support and physical activity‐specific self‐efficacy were analysed.ResultsBased on the actor‐partner interdependence model, we compared nested random intercepts cross‐lagged panel models. The final model revealed no gender effects. Stable levels of both partners’ support provision and self‐efficacy were positively associated. At the time‐varying level, one partner's self‐efficacy predicted the other partner's support provision later on. No lagged‐association emerged for the opposite predictive direction.ConclusionsPartners’ stable shares of provided support and self‐efficacy were interrelated, whereas higher time‐varying self‐efficacy of one partner seemed to activate support provision from the other partner, confirming the cultivation hypothesis but not the enabling hypothesis.
Making New Year's Resolutions that Stick: Exploring how Superordinate and Subordinate Goals Motivate Goal Pursuit
Authors: Höchli Bettina , Brügger Adrian , Messner Claude 
Published: June 2019

BackgroundNew Year's Eve is a time when people make resolutions, but, more often than not, fail to achieve them. Previous research highlighted the positive effect of subordinate goals in goal pursuit. We argue that combining superordinate and subordinate goals contributes to successful goal pursuit, especially in the long run. We test whether a simultaneous focus on both goal types helps people to keep their resolutions.MethodsUsing a 2 × 2 between‐subjects design, participants (N = 256) formulated a resolution from which they derived either a superordinate (yes/no) or a subordinate goal (yes/no). The control group focused exclusively on a self‐set resolution. Main outcome measures were effort in goal pursuit and intentions to further pursue the goal after 3 months.ResultsFocusing on superordinate and subordinate goals increased the amount of effort invested in goal pursuit. A group difference was found only between the group focusing on both goal types and the group focusing on a superordinate goal. No statement could be made about intentions for further goal pursuit and processes by which goal type affects goal pursuit.ConclusionThe study provides preliminary insights into how combining superordinate and subordinate goals may be a helpful strategy to pursue long‐term goals.
Culture, Burnout, and Engagement: A Meta‐Analysis on National Cultural Values as Moderators in JD‐R Theory
Authors: Rattrie Lucy T.B. , Kittler Markus G. , Paul Karsten I. 
Published: June 2019

Despite prominence and increasing application of the Job Demands‐Resources (JD‐R) theory across national contexts, the role of culture has not yet been systematically explored. We conducted a meta‐analysis of 132 independent samples from 120 studies across 5 global regions (total N = 101,073) to fill this void. Our paper responds to long‐standing concerns around neglecting differences in the relationships of workplace factors with burnout and engagement across national cultures by testing for a moderating role within JD‐R theory. Results suggest strong support for the direct job demands‐burnout and job resources‐engagement pathways. Regarding the role of culture, our study reveals moderating roles for five out of six cultural dimensions using Hofstede’s framework. Interestingly, these cultural dimensions present a moderating impact towards relationships with either job demands or job resources, yet not both. Our findings offer a valuable starting point for further theoretical developments that can impact international business and global mobility. While these insights suggest a role of national cultural context in JD‐R studies, sensitivity analyses showed that the findings were only partly stable.

Authors: Yu Jin , Xiang Bo , Song Yun , Chen Hu , Li Youchang , Liu Chun 
Published: June 2019

AbstractObjectivesSufentanil has favourable pharmacodynamic and pharmacokinetic properties as an opioid, and it is usually co‐administered with propofol as intravenous anaesthesia for hysteroscopic examination or therapeutic surgery. However, the optimal dosage of propofol when it is co‐administered with low‐dose sufentanil has not yet been established. This study was designed to find the median effective dose of propofol for intravenous anaesthesia when combined with low‐dose sufentanil.MethodsFifty‐four patients were enrolled and randomized into two groups in this prospective study. Sufentanil 0.2 μg/kg (Group A) or 0.1 μg/kg (Group B) was given intravenously before speculum placement. The initial propofol dose was set at 2 mg/kg and varied by 0.1 mg/kg according to the sequential allocation up‐and‐down rule designed by Dixon and Massey. Respiratory depression, duration of initial dose of propofol, total drug quantity administered and recovery time were recorded.ResultsThe ED50 of propofol was 1.651 mg/kg (95% CI, 1.561‐1.722 mg/kg) in Group A and 1.991 mg/kg (95% CI, 1.902‐2.081 mg/kg) in Group B. The ED95 of propofol was 1.827 mg/kg (95% CI, 1.746‐2.236 mg/kg) in Group A and 2.153 mg/kg (95% CI, 2.070‐2.73 7 mg/kg) in Group B. The initial and total dosage of propofol in Group A were significantly lower than those in Group B, but the incidence of respiratory depression in Group A (26.67%) was significantly higher than that in Group B (4.17%).ConclusionThe ED50 values for propofol when co‐administered with low‐dose sufentanil for intravenous anaesthesia in hysteroscopy were 1.651 mg/kg (sufentanil 0.2 μg/kg) and 1.991 mg/kg (sufentanil 0.1 μg/kg).

Published: June 2019

AbstractIn recent years, gene editing, especially that using clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9, has made great progress in the field of gene function. Rapid development of gene editing techniques has contributed to their significance in the field of medicine. Because the CRISPR/Cas9 gene editing tool is not only powerful but also has features such as strong specificity and high efficiency, it can accurately and rapidly screen the whole genome, facilitating the administration of gene therapy for specific diseases. In the field of tumor research, CRISPR/Cas9 can be used to edit genomes to explore the mechanisms of tumor occurrence, development, and metastasis. In these years, this system has been increasingly applied in tumor treatment research. CRISPR/Cas9 can be used to treat tumors by repairing mutations or knocking out specific genes. To date, numerous preliminary studies have been conducted on tumor treatment in related fields. CRISPR/Cas9 holds great promise for gene‐level tumor treatment. Personalized and targeted therapy based on CRISPR/Cas9 will possibly shape the development of tumor therapy in the future. In this study, we review the findings of CRISPR/Cas9 for tumor treatment research to provide references for related future studies on the pathogenesis and clinical treatment of tumors.

AbstractAimsFunctional brain abnormalities, including altered cerebral perfusion and functional connectivities, have been illustrated in adults with attention‐deficit/hyperactivity disorder (aADHD). The present study attempted to explore the alterations of cerebral blood flow (CBF) and resting‐state functional connectivity (RSFC) simultaneously to understand the neural mechanisms for adults with ADHD comprehensively.MethodsResting‐state arterial spin labeling (ASL) and blood oxygenation level‐dependent (BOLD) magnetic resonance imaging (MRI) data were acquired for 69 male aADHD and 69 matched healthy controls (HCs). The altered CBFs associated with aADHD were explored based on both categorical (aADHD vs HCs) and dimensional (correlation with aADHD core symptoms) perspectives. Then, the seed‐based RSFC analyses were developed for the regions showing significant alterations of CBF.ResultsSignificantly decreased CBF in the large‐scale resting‐state networks regions (eg, ventral attentional network, somatomotor network, limbic network) and subcortical regions was indicated in aADHD compared with HCs. The correlation analyses indicated that the hypoperfusion in left putamen/global pallidum and left amygdala/hippocampus was correlated with ADHD inattentive and total symptoms, respectively. Further, weaker negative functional connectivity between left amygdala and bilateral supplementary motor area, bilateral superior frontal gyrus, and left medial frontal gyrus was found in adults with ADHD.ConclusionThe present findings suggested alterations of both cerebral perfusion and functional connectivity for the left amygdala in aADHD. The combination of CBF and RSFCs may help to interpret the neuropathogenesis of ADHD more comprehensively.
