Impact of economic and market factors on the market liquidity timing ability of mutual fund managers in Turkey
Authors: Yalcin Hale , Dube Sema 
Published: August 2021

PurposeThe authors examine whether Turkish fund managers employ liquidity timing along with market return timing, and if additional economic and market factors could affect their timing abilities, to help explain the contradictory results in literature vis-a-vis market timing ability.Design/methodology/approachThe authors apply panel data analyses, with interaction terms and incorporating structural breaks, to monthly data for 96 out of 131 Turkish variable mutual funds which have available data for the sample period of 2011–2018. The authors employ the Amihud (2002) illiquidity measure to study market liquidity timing ability along with how additional economic and market factors affect this ability.FindingsThe authors find liquidity timing to be the performance enhancing method employed by Turkish variable fund managers in conjunction with market timing and that evidence for market timing may depend on whether structural breaks, that may be present in returns, are incorporated in the analysis. The authors also find that economic, technology and market-related factors affect timing abilities of fund managers.Research limitations/implicationsConclusions are for Turkey, for the sample period studied, and for the control factors selected based on literature.Practical implicationsIt is important to understand the role of market liquidity in making investment decisions and the paper contributes toward an understanding of how managers design their timing strategies in order to enhance portfolio performance, as well as the impact of additional factors on their ability to time market returns and liquidity. This is also important for evaluating fund managers' performance in terms of contribution to portfolio value.Originality/valueTo the authors knowledge this is the first study on Turkish markets to employ liquidity timing in the context of panel data analyses using interaction terms, as well as structural breaks, to distinguish the extent of liquidity timing from return timing, while incorporating the effect of additional factors on timing ability.
Impact of financial inclusion on economic development of marginalized communities through the mediation of social and economic empowerment
Authors: Lal Tarsem 
Published: August 2021

PurposeThe purpose of this paper is to check the impact of financial inclusion on economic development of marginalized communities through the mediation of socio-economic empowerment.Design/methodology/approachIn order to fulfil the objectives of the study, primary data were collected from 382 bank customers belonging to marginalized communities breathing in Jammu district of J and K by using purposive sampling technique. The data were collected during the month of April–August 2020. Multivariate statistical techniques such as EFA, CFA and SEM were used for data analysis and scale purification.FindingsThe study’s results reveal that financial inclusion has a direct and significant impact on economic development of marginalized communities through the mediation of social and economic empowerment. The study highlights that despite various initiatives taken by the government towards financial inclusion, there is a denial from the financial institutions to extend the credit to the marginalized communities due to lack of education, illiteracy, lack of awareness, attitude of bankers and policy directions to the banking sector, which confine these communities to feel proud, dignified, confident and self-reliant to face any financial crisis.Research limitations/implicationsFirst the in-depth analysis of the study is restricted to Jammu district only that restricts the generalization of the results to the whole population of J and K. Second, the data were collected from respondents belonging to marginalized communities only. Third, comparative study of marginalized households who are covered under the financial inclusion drive and those who are still financially excluded has not been done yet. Fourth, the questionnaire approach was the only way to gather primary data and thus, the results might have a common-method bias.Originality/valueThe study makes contribution in the direction of financial inclusion narrative relating to socio-economic empowerment and economic development of marginalized communities. It looks into how for the socio-economic aspects of marginalized communities influence their exclusion from the financial system of the country. The study also provides valuable insights for the policymakers, researchers and academicians both at the countrywide and intercontinental level to devise and put into practice programmes that will widen right to use financial products and services leading to cutback of poverty incidence, income parity, social and economic empowerment, economic development and reduction in caste and gender based discrimination.
Reconstruction and information entropy analysis of frictional vibration signals in running-in progress
Authors: Yu Haijie , Wei Haijun , Zhou Daping , Li Jingming , Liu Hong 
Published: August 2021

Purpose
This study aims to reconstruct the frictional vibration signal from noise and characterize the running-in process by frictional vibration.

Design/methodology/approach
There is a strong correlation between tangential frictional vibration and normal frictional vibration. On this basis, a new frictional vibration reconstruction method combining cross-correlation analysis with ensemble empirical mode decomposition (EEMD) was proposed. Moreover, the concept of information entropy of friction vibration is introduced to characterize the running-in process.

Findings
Compared with the wavelet packet method, the tangential friction vibration and the normal friction vibration reconstructed by the method presented in this paper have a stronger correlation. More importantly, during the running-in process, the information entropy of friction vibration gradually decreases until the equilibrium point is reached, which is the same as the changing trend of friction coefficient, indicating that the information entropy of friction vibration can be used to characterize the running-in process.

Practical implications
The study reveals that the application EEMD method is an appropriate approach to reconstruct frictional vibration and the information entropy of friction vibration represents the running-in process. Based on these results, a condition monitoring system can be established to automatically evaluate the running-in state of mechanical parts.

Originality/value
The EEMD method was applied to reconstruct the frictional vibration. Furthermore, the information entropy of friction vibration was used to analysis the running-in process.
Comparative study of different solid lubricants towards friction stability in a non-asbestos disc brake pad
Authors: P. Baskara Sethupathi , J. Chandradass 
Published: August 2021

Purpose
This study aims to compare the influence of different solid lubricants on the friction stability of a non-asbestos disc brake pad.

Design/methodology/approach
Three brake pads were developed using three lubricants, namely, non-asbestos brake pad with sulfide mix (NASM), non-asbestos brake pad with bismuth sulfide (NABS) and non-asbestos brake pad with molybdenum disulfide (NAMO). Sulfide mix was indigenously developed by physically mixing friction modifiers, alkaline earth chemicals and various metallic sulfides homogeneously dispersed in graphite medium. The physical, chemical, mechanical and thermal properties of brake pads were characterized as per industrial standards. The tribological performances were studied using the Chase testing machine as SAE-J661-2012. The worn surface of the pads was studied using scanning electron microscope to analyze the dominating wear mechanism.

Findings
NASM was excellent in fade as well as wear resistance. NABS was better from a wear point of view, but fade resistance was moderate despite its higher cost. NAMO fared average in fade and wear despite its excellent dry lubricating properties. NASM was excellent in terms of fade as well as wear resistance.

Originality/value
Among the selected metal sulfides, the indigenously developed sulfide mix was better than the other two sulfides, which indicates that the synergetic effect of metal sulfides was always preferable to the individual sulfides.
The fringe or national brand manufacturer? An analysis of private label sourcing strategy
Authors: Li Xue 
Published: August 2021

PurposePrivate labels (PLs) have flowed into a wide range of categories and continue to expand especially in the mass channel. This paper aims to investigate the optimal PL sourcing strategy for a retailer and the impact of different sourcing strategies on the interaction between the upstream national brand (NB) manufacturer and the downstream retailer in a dyadic supply chain.Design/methodology/approachThe authors develop a game-theoretic model that allows for vertical differentiation, where a retailer may choose between two types of PL sourcing strategies, i.e. fringe and NB manufacturer sourcing (NBMS). Under fringe manufacturer sourcing, the procurement cost is low but the PL recognition is also low. There exists a group of loyal consumers who only choose the NB. Under NBMS, the procurement cost is high but the loyal consumers may switch between two products. The channel members engage in a three-stage sequential game and the authors analyze the subgame perfect equilibrium by comparing the retailer’s best profits in the two subgames, i.e. fringe and NBMS.FindingsThe model shows that the retailer inclines to source from the NB manufacturer if the size of the loyal consumer group is relatively large, which provides a rationale for the existence of NBMS. It is also shown that the NB quality plays a positive role on NBMS. As the NB quality becomes higher, the retailer is more likely to procure the PL from the NB manufacturer instead of the fringe manufacturer. In addition, both channel members can be better off and more consumer surplus is provided by expanding the market under NBMS. Overall, sourcing from the NB manufacturer may improve channel profit, consumer welfare and social welfare.Originality/valueThe research contributes to explaining why the practice of sourcing PLs from NB manufacturers is widely adopted by retailers and can help retailers to make appropriate PL sourcing strategies under various circumstances.
The relationship between political connections, auditor characteristics and auditor narcissism
Authors: Khaksar Jalil , Salehi Mahdi , Lari DashtBayaz Mahmoud 
Published: August 2021

Purpose
This study aims to assess the relationship between political connections, auditor characteristics (audit quality and industry specialization) and auditors’ intrinsic characteristics (narcissism) in listed firms on the Tehran Stock Exchange. In other words, this paper attempts to answer the question “whether political connections, audit quality and industry specialization contribute to the growth of narcissism and overconfidence of auditors of listed firms on the Tehran Stock Exchange or not.”

Design/methodology/approach
A multivariate regression model is used for hypothesis testing. The study’s hypotheses were also examined using a sample of 768-year firm listed on the Tehran Stock Exchange during 2013–2018 and by using the multiple regression pattern.

Findings
The obtained results indicate a negative and significant association between political relations, narcissism and overconfidence. The auditor’s overconfidence will go down by increasing political relations. Moreover, the results show a positive and significant relationship between audit quality, industry specialization and narcissism. On the other hand, to the best of authors’ knowledge, this study measured, for the first time, the severity of political connections by using the exploratory factor analysis of eight variables (long-term liabilities, firm size, financial leverage, export, human resources, major governmental shareholders, board members affiliated to the government and institutional ownership).

Originality/value
The authors figured out that few studies carried out, so far, in the emergent markets on political connections and their impacts on narcissism and overconfidence of auditors, so this paper aims to assess the effect of such a phenomenon in the emergent markets and contributes to the development of knowledge and science in this field.

Beyond species richness and community composition: Using plant functional diversity to measure restoration success in jarrah forest
Authors: Standish Rachel Jayne , Gove Aaron David , Grigg Andrew Haden , Daws Matthew Ian 
Published: August 2021

AbstractAimThe importance of restoring ecosystem functions to native systems that have been degraded, damaged or destroyed is increasingly recognised. Yet few studies have measured the effect of restoration efforts on ecosystem functioning or the functional diversity (FD) that underpins it. Here we assessed change in FD of restored assemblages one to 25 years after the onset of post‐mine restoration.LocationNorthern Jarrah (Eucalyptus marginata Donn ex Sm.) Forest bioregion of southwestern Australia.MethodsFunctional richness, evenness, divergence and dispersion were derived from five plant functional traits relevant to community reassembly. Effects of three explanatory variables (i.e. age, year restoration was initiated, and time since fire) on six response variables (i.e. four FD indices, species richness, and compositional similarity to nearby reference forest) were analysed using linear mixed models for a data set with repeated measures of plots through time (n = 810 plots), and linear models for a subset of one‐time measures of different aged assemblages (i.e. space‐for‐time approach; n = 490 plots).ResultsFunctional evenness and functional dispersion increased with age, while functional divergence and functional richness decreased with age. Functional dispersion increased with time since fire, while functional richness decreased with time since fire. Species richness decreased with age, but at 25 years, species richness was comparable to that observed in reference forest. In contrast, similarity showed no relationship with age of restored forest, and at 25 years, similarity of restored forest to reference was low compared with similarity of reference forest to itself. Three of four FD indices had not reached those of reference jarrah forest 25 years after restoration had been initiated.ConclusionsReassembly of FD suggests importance of environmental filtering and high functional redundancy. A longer time frame may be needed to assess FD of restored assemblages, and in the meantime, species richness is not an adequate surrogate of FD.

AimsIxekizumab is a high‐affinity monoclonal antibody that selectively targets interleukin‐17A used in the treatment of adult and paediatric patients with moderate‐to‐severe psoriasis. This analysis evaluated the pharmacokinetics (PK) of ixekizumab and the exposure–efficacy relationship in paediatric patients aged 6 to <18 years with psoriasis.MethodsPopulation PK and exposure–efficacy models were developed. The models used data from paediatric patients with psoriasis participating in the Phase 3 IXORA‐PEDS trial in which patients were dosed according to weight categories. The exposure–efficacy model is a Psoriasis Area and Severity Index (PASI) time course model using data up to Week 12, a co‐primary efficacy endpoint.ResultsA 2‐compartment population PK model describes the PK of ixekizumab in paediatric patients with the effect of body weight incorporated on clearance and volume terms using an allometric relationship. The weight category‐based dosing ensured that ixekizumab mean trough serum concentrations in paediatric patients with psoriasis (3.20–3.33 μg/mL) were within the range of concentrations observed in adult patients with psoriasis (mean [standard deviation]: 3.48 [2.16] μg/mL) administered an efficacious dosing regimen. The observed PASI response rates at Week 12 in paediatric patients (91.9/81.8/52.5% for PASI75/90/100) are well predicted by the final exposure–efficacy model and response rates are similar or higher than those achieved in adults (86.2/66.6/35.0% for PASI75/90/100).ConclusionThis analysis is the first to describe the PK and exposure–efficacy relationship of ixekizumab in paediatric patients with psoriasis. The analyses support the selection of the weight category‐based ixekizumab dosing regimens approved for use in paediatric patients with psoriasis.

SummaryRecent large‐scale genetic studies have proposed a new genetic classification of diffuse large B‐cell lymphoma (DLBCL), which is clinically and biologically heterogeneous. However, the classification methods were complicated to be introduced into clinical practice. Here we retrospectively evaluated the mutational status and copy number changes of 144 genes in 177 Japanese patients with DLBCL, using targeted DNA sequencing. We developed a simplified algorithm for classifying four genetic subtypes—MYD88, NOTCH2, BCL2, and SGK1—by assessing alterations in 18 representative genes and BCL2 and BCL6 rearrangement status, integrating the significant genes from previous studies. In our cohort and another validation cohort from published data, the classification results in our algorithm showed close agreement with the other established algorithm. A differential prognosis among the four groups was observed. The NOTCH2 group showed a particularly poorer outcome than similar groups in previous reports. Furthermore, our study revealed unreported genetic features in the DLBCL subtypes that are mainly reported in Japanese patients, such as CD5‐positive DLBCL and methotrexate‐associated lymphoproliferative disorders. These results indicate the utility of our simplified method for DLBCL genetic subtype classification, which can facilitate the optimisation of treatment strategies. In addition, our study highlights the genetic features of Japanese patients with DLBCL.
Molecular imaging of cardiovascular inflammation
Authors: MacRitchie Neil , Noonan Jonathan , Guzik Tomasz J. , Maffia Pasquale 
Published: August 2021

Cardiovascular diseases (CVDs), including atherosclerosis, are chronic inflammatory diseases characterised by a complex and evolving tissue micro‐environment. Molecular heterogeneity of inflammatory responses translates into clinical outcomes. However, current medical imaging modalities are unable to reveal the cellular and molecular events at a level of detail that would allow more accurate and timely diagnosis and treatment. This is an inherent limitation of the current imaging tools, which are restricted to anatomical or functional data. Molecular imaging—the visualisation and quantification of molecules in the body—is already established in the clinic in the form of PET, yet the use of PET in CVD is limited. In this visual review, we will guide you through the current state of molecular imaging research, assessing the respective strengths and weaknesses of molecular imaging modalities, including those already being used in the clinic such as PET and MRI and emerging technologies at preclinical stage, such as photoacoustic imaging. We discuss the basic principles of each technology and provide key examples of their application in imaging inflammation in CVD and the added value into the diagnostic decision‐making process. Finally, we discuss the barriers to the rapid successful clinical translation of these novel diagnostic modalities.LINKED ARTICLESThis article is part of a themed issue on Molecular imaging ‐ visual themed issue.

Published: August 2021

AbstractBackgroundChlorhexidine (CHX) is a broad‐spectrum antimicrobial agent commonly used in medicine. Application of (CHX) during abutment connection reduced the bacterial load at the implant–abutment interface. We hypothesize this treatment may consequently reduce peri‐implant soft tissue inflammation and marginal bone loss.PurposeTo evaluate the effect of a single application of CHX gel inside the dental implant internal hexagon on peri‐implant tissue.MethodsForty patients were recruited to this randomized, double‐blinded, clinical trial. At the time of implant installation, a 4‐mm healing abutment was connected to the implant. In the test group, chlorhexidine gel 1% was applied inside the implant hex, whereas control implants did not receive any gel. Clinical and radiographic measurements included soft tissue recession (REC), plaque index (PI), gingival index (GI), plaque index (PI), keratinized mucosa width (KM), probing depth (PD), and a peri‐apical parallel x‐ray. Peri‐implant crevicular fluid (PICF) was collected for cytokine analysis. t‐Test was used to compare changes from baseline to 3 months. Mann–Whitney U test and t test were used to compare test and control groups.ResultsTwenty patients in the test group and 17 in the control group completed the study. One implant in the control group failed to osteointegrate. There were no significant differences between the control and test groups for REC changes, bone loss, and PD. GI was significantly lower in the test group after 1 week (1.79 ± 0.24 vs 0.75 ± 0.18, respectively) and 3 months (1.18 ± 0.21 vs 0.25 ± 0.12, respectively) although PI was equal. At 3 months, interleukin 1‐β (IL1‐β) was higher in the control group (p < 0.01) and a positive correlation was found between GI and IL1‐β (rs = 0.60424, p = 0.00032).ConclusionsApplication of chlorhexidine gel reduced inflammation and IL1‐β levels in the peri‐implant soft tissue.
