Machine learning methods for results merging in patent retrieval
Authors: Stamatis Vasileios , Salampasis Michail , Diamantaras Konstantinos 
Published: March 2023

PurposeIn federated search, a query is sent simultaneously to multiple resources and each one of them returns a list of results. These lists are merged into a single list using the results merging process. In this work, the authors apply machine learning methods for results merging in federated patent search. Even though several methods for results merging have been developed, none of them were tested on patent data nor considered several machine learning models. Thus, the authors experiment with state-of-the-art methods using patent data and they propose two new methods for results merging that use machine learning models.Design/methodology/approachThe methods are based on a centralized index containing samples of documents from all the remote resources, and they implement machine learning models to estimate comparable scores for the documents retrieved by different resources. The authors examine the new methods in cooperative and uncooperative settings where document scores from the remote search engines are available and not, respectively. In uncooperative environments, they propose two methods for assigning document scores.FindingsThe effectiveness of the new results merging methods was measured against state-of-the-art models and found to be superior to them in many cases with significant improvements. The random forest model achieves the best results in comparison to all other models and presents new insights for the results merging problem.Originality/valueIn this article the authors prove that machine learning models can substitute other standard methods and models that used for results merging for many years. Our methods outperformed state-of-the-art estimation methods for results merging, and they proved that they are more effective for federated patent search.
Asymmetric link between economic well-being and labour market equity in Turkey
Authors: Beton Kalmaz Demet 
Published: March 2023

PurposeFemale labour force participation (FLFP) is undeniably critical for both developing and developed countries. This study aims to investigate the impact of economic risk on FLFP, controlling economic well-being, fertility rate and education, considering the asymmetric relationship among the indicators in Turkey.Design/methodology/approachTime series data covering years from 1988Q1 to 2019Q4 is deployed for the empirical analysis to identify the long-run asymmetric link. Empirical analysis of the study starts with the employment of the Augmented Dickey-Fuller unit root test with the breakpoint to test for the order of integration of time series and to capture the breakpoints. The Brock-Dechert-Scheibkman test is applied to determine if or not the econometric model is correctly identified. Nonlinear autoregressive distributed lag (NARDL) bounds test is used to examine the existence of an asymmetric link between FLFP and economic well-being. The empirical analysis follows the investigation of the determinants of FLFP through the employment of the NARDL model.FindingsThe existence of long-run link among the time series is confirmed through the results obtained from the NARDL bounds test. Furthermore, long-run NARDL estimations confirm that (i) positive shocks in economic well-being increases FLFP; (ii) positive shock in education negatively impacts FLFP; (iii) FLFP is negatively affected by economic risk; and (iv) finally, increased fertility rate increases FLFP in Turkey.Originality/valueThis paper is checked from turnitin for the plagiarism which is estimated to be less than 20%. It is an original paper that fills the gap in literature and provides meaningful insight both for the policymakers and academics.

Authors: Wang Rensheng , Sun Cong , Xiu Shichao , Wang Qi , Liang Dongming , Zhao Qi 
Published: March 2023

Purpose
This paper aims to study the effects of the processing parameters in the reciprocating magnetorheological polishing (RMRP) on abrasive particle trajectory by the simulation analysis, which provides a basis for the machining uniformity of the workpiece.

Design/methodology/approach
The principle of the RMRP method is discussed, and a series of simulation analysis of the abrasive particle trajectory are performed to evaluate the effects of the workpiece’s rotational speed, the eccentric wheel’s rotational speed, the eccentricity and the frame gap on abrasive particle trajectory by using the RMRP method.

Findings
The processing parameters have a significant influence on the abrasive particle trajectory, and then the machining uniformity of the workpiece is affected. Under certain experimental conditions, the height difference of workpiece measuring points varies between 4 and 11 µm, and the height difference of equal radial measuring points is less than 1.5 µm by optimizing processing parameters.

Originality/value
In this study, the optimal processing parameters can be obtained by the simulation analysis of abrasive particle trajectory, which can replace the experimental methods to obtain the reasonable processing parameters for the machining uniformity of the workpiece. It provides references for the selection of processing parameter values in magnetorheological polishing process.

Published: March 2023

Purpose
Public higher education institutions (HEIs) infrastructure funding is challenging in many developing countries. Encouraging private investment in HEIs infrastructure via a developed expanded corporate social responsibility (ECSR) may improve physical facilities. ECSR is a form of infrastructure tax relief providing physical facilities for HEIs. Academic literature is scarce concerning how ECSR can improve Nigeria’s public HEIs infrastructure and achieve education infrastructure related to Sustainable Development Goal 4 (SDG 4). Therefore, this study aims to proffer measures to improve public HEIs infrastructure and achieve sustainable development connected to Goal 4 focussing on infrastructure via a developed framework.

Design/methodology/approach
This is an expansion of an ongoing study, and data were collated via virtual interviews across the six geo-political zones in Nigeria. The analysed data were presented in a thematic pattern.

Findings
A total of 18 measures (sub-variables) emerged and were re-grouped into six variables. This includes institutionalising ECSR, HEIs infrastructure via ECSR awareness, HEIs infrastructure incentives, national and state action plans on HEIs infrastructure, a legal framework for HEIs infrastructure and key stakeholders’ participation. Also, the study used the generated six main variables to develop the improved public HEIs infrastructure via ECSR in developing countries, using Nigeria as a case study. This can enhance achieving infrastructure associated with SDG 4 (quality education) and targets.

Originality/value
This study intends to develop the philosophy (ECSR) with an implementable framework to encourage the private sector further to expand their CSR in the infrastructure development to the educational sector, especially in developing countries higher institutions, using Nigeria as a case study.

Published: March 2023

PurposeWhile the economic benefits of the exhibition industry for the hotel sector have been addressed, the impact of exhibitions on individual hotels is unknown, especially when individual hotels’ star classification and locations are considered. This study aims to provide a better understanding of how room rates of different hotels change during different stages of the Canton Fair in China from a spatial-temporal perspective.Design/methodology/approachRoom rates of 681 star-hotels within the city of Guangzhou before, during and after the Fair were extracted from websites. Through spatial interpolation and autocorrelation analysis and geographical detector (GeoDetector) technique, spatial and temporal patterns of hotel room rates and the interdependence between the convention center and the hotels with different star classification and locations were examined.FindingsAn inverse-U shape of room rate change was identified before, during and after the Fair, and the five-star hotels had the sharpest increase. Moreover, the distribution of hotel room rates followed the law of distance decay. The variation of hotel rates became larger when the distance to the convention center was larger. Spatial high-high clusters varied among hotels with different star classification.Originality/valueThis study contributed to the hotel literature by providing empirical evidence regarding how hotels with different star classification and locations were affected by events. This study also advanced the event literature by introducing GeoDetector. The findings of this study offered insights into the hotel location selection, pricing strategies and hotel collaboration with events.

Authors: Bozkurt Sıddık , Gligor David , Locander Jennifer , Ahmad Rather Raouf 
Published: March 2023

PurposeThis study aims to contribute to the social media agility literature by examining the impact of perceived social media agility on customer purchases. More specifically, this study seeks to reveal whether perceived social media agility positively affects customer purchases. Furthermore, this study examines the moderating roles of social media self-efficacy and social anxiety to increase the model's explanatory power. That is, this study investigates whether social media self-efficacy positively moderates the impact of perceived social media agility on customer purchases. Similarly, this study examines whether social anxiety negatively moderates the impact of perceived social media agility on customer purchases.Design/methodology/approachAn online survey was conducted on Qualtrics platforms to test the research hypotheses. To test the main effect, a linear regression was used. To test moderating relationships, PROCESS Macro Model 1 was used. Finally, the moderating effects were probed with the Johnson–Neyman technique to gain further insights into the interaction effects.FindingsThe study results show that when customers perceive a brand as agile on social media platforms, they are more willing to buy the goods/services of the brand. Notably, individuals who are high on social media self-efficacy (relative to low on it) display more willingness to purchase the brand's products/services. However, customers who are high on social anxiety (relative to low on it) are less willing to purchase the brand's products/services.Originality/valueThis study examines the effect of perceived social media agility on customer purchases while accounting for the moderating role of perceived social media self-efficacy and social anxiety. The results provide noteworthy theoretical and managerial contributions.
Cultural capital and perception of teacher‐student relationships: Uncovering inequalities at schools in China
Authors: Olivos Francisco , Araki Satoshi 
Published: March 2023

AbstractA long tradition in stratification research argues students with higher cultural capital are likely to be treated by their teachers as possessing the “right culture,” which positively affects their academic performance. Nevertheless, the literature has paid little attention to the role of students' perception in this process. Using two waves of the China Educational Panel Survey, we investigate how students' cultural capital affects their own understanding of teacher‐student interactions, including its gender difference. Fixed effects regressions show a substantially positive effect of cultural capital on the perceived frequency of teachers praising and calling on students to answer questions across subjects. Nonetheless, we also find the lack of cultural capital is not punished and that the cultural capital's effect varies across its specific components and gender. These findings pave the way for elucidating the entire causal chain of intergenerational social inequality via cultural capital, teacher bias, students’ perception, and their educational outcomes.
Profession and residency matter: Farmers' preferences for farmland price regulation in Germany
Authors: Jauernig Johanna , Brosig Stephan , Hüttel Silke 
Published: March 2023

AbstractLocal farmers' preferences for farmland price regulations in competitive markets have not been studied systematically. We investigate farmers' preferences in Germany, where recent price increases have driven calls for regulatory changes. The results of an online vignette experiment show that farmers prefer stricter regulation against the admission of non‐local (but even more so of non‐farmer) land buyers. Our analysis also shows that local farmers' preferences are motivated primarily by self‐interest rather than adherence to principles. We conclude that most farmers prefer price regulations that consider their particular concerns about increasing competition in Germany.
Research progress on the application of different controlling strategies to minimizing ethyl carbamate in grape wine
Authors: Deng Huan , Ji Lin , Han Xiaoyu , Wu Tianyang , Han Bing , Li Chenyu , Zhan Jicheng , Huang Weidong , You Yilin 
Published: March 2023

AbstractEthyl carbamate (EC) is a probable carcinogenic compound commonly found in fermented foods and alcoholic beverages and has been classified as a category 2A carcinogen by the International Agency for Research on Cancer (IARC). Alcoholic beverages are one of the main sources of EC intake by humans. Therefore, many countries have introduced a standard EC limit in alcoholic beverages. Wine is the second largest alcoholic beverage in the world after beer and is loved by consumers for its rich taste. However, different survey results showed that the detection rate of EC in wine was almost 100%, while the maximum content was as high as 100 μg/L, necessitating EC content regulation in wine. The existing methods for controlling the EC level in wine mainly include optimizing raw fermentation materials and processes, using genetically engineered strains, and enzymatic methods (urease or urethanase). This review focused on introducing and comparing the advantages, disadvantages, and applicability of methods for controlling EC, and proposes two possible new techniques, that is, changing the fermentation strain and exogenously adding phenolic compounds. In the future, it is hoped that the feasibility of this prospect will be verified by pilot‐scale or large‐scale application to provide new insight into the regulation of EC during wine production. The formation mechanism and influencing factors of EC in wine were also introduced and the analytical methods of EC were summarized.

Authors: Wang Jiaqi , Ma Tingting , Wei Mengyuan , Lan Tian , Bao Shihan , Zhao Qinyu , Fang Yulin , Sun Xiangyu 
Published: March 2023

AbstractHeavy metals are of particular concern in grape and wine processing, especially copper. The sources of copper are diverse, including vineyard soil, copper‐containing pesticides on the fruit surface, copper wine‐making equipment, and exogenous addition in winemaking. Copper has potential risks to human nerves, metabolism, and others. It can inhibit yeast growth, delay fermentation, and also mediate oxidation reactions, which has a huge impact on the nutritional quality and sensory quality of fresh wine and aged wine. It is therefore crucial to detect, quantify, and remove copper from grapes and wine. However, the copper situations in the wine industries of various countries are complicated and diverse, and the existing forms of copper are quite different, which makes the research challenging. This review summarizes and analyzes the existence and influence of copper in the wine industry by analyzing the sources of, the current situation regarding, and the detection and removal methods for copper in wine. With the study, a better understanding of copper's impact on wine production will be gained, facilitating further control of copper in wine and helping the wine industry grow.

Published: March 2023

AbstractVolatile compounds in wine have a critical impact on the consumers’ senses. In this study, the effect of diammonium phosphate (DAP) and glutamine on sulfur‐containing volatiles and sensory properties of Chardonnay wine fermented with Saccharomyces cerevisiae yeast were evaluated. Fermentation kinetics was determined by monitoring reducing sugar consumption rates during fermentation. The volatile profile of wines was analyzed by headspace solid phase microextraction (HS‐SPME) coupled with gas‐chromatography‐mass spectrometry (GC‐MS). The volatile sulfur compounds (VSCs) were analyzed by HS‐SPME‐GC‐MS/MS. Flavor attributes of wines were assessed by a sensory panel with quantitative descriptive analysis. A total of 53 volatiles, including 6 VSCs, were identified and quantified in the Chardonnay wine. The results suggested that glutamine supplementation at the beginning of fermentation could help to initiate fermentation earlier and promote the formation of isoamyl acetate, phenethyl acetate, ethyl nonanoate, methyl decanoate, diethyl succinate and phenethyl alcohol, isobutanol, while DAP supplementation had no obvious effect on the volatile composition of the resulting wine and fermentation kinetics.Practical ApplicationSuitable nitrogen source is helpful to a healthy fermentation, and can also prevent the off‐flavor and regulate aroma profile of wine. This study provides insights on the volatile and sensory characteristics of Chardonnay wines affected by different nitrogen source addition.
