The impact of income growth on quality structure improvement of imported food: evidence from China's firm-level data
Authors: Sun Lin , Ye Li Tao , Reed Michael R. 
Published: August 2020

PurposeAgainst the background of the rapid increase of total imported food in China, China's imported high-quality food has increased more than low-quality ones, and China's imported food quality structure has continuously improved. It is a new issue that needs further examination.Design/methodology/approachBased on the assumption of non-homothetic preference, this paper apply the method provided by Eaton and Kortum (2002) in a new theoretical model and empirically analyzes the impact of per capita income on the quality structure of imported food by using SYS-GMM with firm import data from Chinese customs.FindingsThe study finds that income is a significant factor which affects the imported food quality structure in China. The higher the per capita income, the higher the imported food quality structure. Furthermore, per capita income has a significant positive impact on the imported food quality structure in different quality groups. The research confirms that China import more food with the highest quality as its per capita income increases.Research limitations/implicationsChinese policymaker needs to reconsider the role of food imports in improving food quality structure. The aim of the Chinese food industry's supply-side reform should be not only to remove excess capacity but also to produce high-quality products that meet the demand of discriminating consumers.Originality/valueThis paper constructs a new theme for imported food quality structure and investigates import food quality structure improvement from the perspective of demand by incorporating non-homothetic preferences. Another feature of this paper is that it conducts an empirical analysis with unique and highly disaggregated firm import data from Chinese customs to measure imported food quality, which is more refined than the national-product dimension data.
Organisational learning as a mediator in the host-home country similarity–international firm performance link: the role of exploration and exploitation
Authors: Arzubiaga Unai , Castillo-Apraiz Julen , Palma-Ruiz Jesús Manuel 
Published: August 2020

Purpose
This study aims to shed light on the lack of understanding and previous mixed results regarding why and how some internationalised firms take advantage of host-home country similarity (HHS) while others do not.

Design/methodology/approach
Direct and mediating hypotheses are examined through an empirical investigation of 156 CEOs in internationalised Spanish companies, using structural equation modelling validated by factor analysis.

Findings
The results suggest that exploitation (EI) and exploration (ER) constitute important learning mechanisms that impact on the liability of foreignness when internationalising a business. In particular, the positive influence that HHS has in international firm performance (IP) depends on both exploitative and exploratory learning.

Practical implications
This research adds insights into the importance of two of the main components of organisational learning (i.e. ER and EI) as mediators of the HHS and IP relationship, which can help senior managers or business owners make consistent decisions by matching potential international market locations with firm learning factors.

Originality/value
This study clarifies contradictory theoretical assertions and mixed empirical results about how HHS impacts on international performance. In particular, by responding to recent calls for research, this study has shown that organisational learning is a key component in the aforementioned link where ER and EI positively mediate this relevant relationship.
Numerical simulation of the electric field induced in a contactless dielectrophoretic quadrupole cell separator
Authors: Tada Shigeru 
Published: August 2020

Purpose
This study aims to propose a contactless and continuous dielectrophoretic cell-separation device using quadrupole electric field. To examine the separation performance, numerical simulations of the electric field in the cross-section of the glass capillary installed in the center of the quadrupole electrode were conducted.

Design/methodology/approach
To estimate the magnitude of the dielectrophoretic force induced on cells, electrostatic analysis was performed by using a boundary-fitted coordinate system.Distribution of the electric field and gradient of the electric field square in the cross-section of the glass capillary were simulated for various ratios of radii of the glass capillary to the electrode rod.

Findings
The distribution of the electric field was found to have a cone-like profile about the center axis of the glass capillary with maximum at the internal surface of the glass capillary. The magnitude of the gradient of electric field square had similar distribution as that of the electric field, but had steeper slope near the internal surface of the glass capillary. The optimal values of the ratio of radii and the applied voltage were also estimated to achieve the local electric field strength suitable for cell separation.

Originality/value
One major advantage of the proposed device is simple and low fabrication cost, in addition to its contactless structure free from cell damage. Derived knowledge is instructive in achieving high-throughput cell separation without the use of devices of complex structure.
The role of firm location and agglomeration economies on export propensity: the case of Portuguese SMEs
Authors: Forte Rosa Portela , Sá Ana Rita 
Published: August 2020

PurposeThe present study seeks to assess whether the firm's location and agglomeration economies affect the firm's export propensity.Design/methodology/approachThis work is based on a sample of 20,234 Portuguese manufacturing small and medium enterprises (SMEs) and resort to the estimation of a probit model.FindingsEmpirical results show that the location and agglomeration economies have an important role in determining the firm's export propensity. In particular, the study concludes that SMEs located in coastal areas or close to the border are more likely to export. Furthermore, the study also concludes that specialization economies are an important driver of small and medium-sized firms' export propensity while export spillovers are particularly relevant for micro firms. However, urbanization, measured through firms density in NUTS3 region, negatively affects firms' export propensity, which may be due to high congestion costs in the regions with a high firms density.Originality/valueThis study focus on the determinants of the decision to export or the export propensity, particularly the external factors such as the firm's location and agglomeration economies. This is a relatively neglected topic in the literature that has focused on the determinants of export intensity.
A new similarity solution with stability analysis for the three-dimensional boundary layer of hybrid nanofluids
Authors: Khashi'ie Najiyah Safwa , Arifin Norihan M. , Pop Ioan , Nazar Roslinda , Hafidzuddin Ezad Hafidz 
Published: August 2020

Purpose
The purpose of this study is to implement a new class of similarity transformation in analyzing the three-dimensional boundary layer flow of hybrid nanofluid. The Cu-Al2O3/water hybrid nanofluid is formulated using the single-phase nanofluid model with modified thermophysical properties.

Design/methodology/approach
The governing partial differential equations are reduced to the ordinary (similarity) differential equations using the proposed similarity transformation. The resulting equations are programmed in Matlab software through the bvp4c solver to obtain their solutions. The features of the reduced skin frictions and the velocity profiles for different values of the physical parameters are analyzed and discussed.

Findings
The non-uniqueness of the solutions is observed for certain physical parameters. The dual solutions are perceived for both permeable and impermeable cases and being the main agenda of the work. The execution of stability analysis proves that the first solution is undoubtedly stable than the second solution. An increase in the mass transpiration parameter leads to the uniqueness of the solution. Oppositely, as the injection parameter increase, the two solutions remain. However, no separation point is detected in this problem within the considered parameter values. The present results are decisive to the pair of alumina and copper only.

Originality/value
The present findings are original and can benefit other researchers particularly in the field of fluid dynamics. This study can provide a different insight of the transformation that is applicable to reduce the complexity of the boundary layer equations.

Authors: Moscovici Daniel , Rezwanul Rana , Mihailescu Radu , Gow Jeff , Ugaglia Adeline Alonso , Valenzuela Lionel , Rinaldi Azzurra 
Published: August 2020

Purpose
This study aims to analyze the wine industry’s response to changing societal attitudes towards the environment. Environmental considerations are now an increasingly important factor in both production and purchasing behavior. While many eco-certifications exist, there is still consumer confusion between the multitude of eco wine certifications, lack of clarity about what consumers think about the wines, and not enough data about their willingness to pay (WTP) for these environmental characteristics.

Design/methodology/approach
This study clarifies what the various wine eco certifications are, quantifies consumer knowledge and ascertains their WTP for five environmental or sustainable wine certifications, namely, biodynamic, fair trade, organic, natural and sustainable. The authors surveyed 456 wine drinkers in the USA.

Findings
The authors found that millennials, women, unmarried individuals, those purchasing eco-certified foods, low-income individuals and those looking to celebrate a special occasion have a higher WTP for eco-certified wines compared to respondents who are older, male, married, do not buy eco-certified goods, have higher incomes and are purchasing the wine for a regular occasion. They recommend marketing and targeting those in the former group for environmental or sustainable wines.

Originality/value
The study is the only research project, of this kind, to evaluate five types of eco-certifications for wine in a single WTP analysis.
Investigating the role of leader-member exchange for goal commitment in system implementation
Authors: Hwang Yujong , Kim Soyean , Shin Donghee 
Published: August 2020

PurposeAlthough Leader-Member Exchange (LMX) has been studied within the domain of organizational psychology, it has not received major attention from information systems literature and researchers. Drawing on LMX theory and the theory of reasoned interaction, this study investigates the roles of LMX, individual member's attitude toward system adoption, supervisor influence and goal commitment on mandatory system implementation. Specifically, our model investigates the moderating role of LMX and how it can be interpreted for an individual member's system adoption in an organization.Design/methodology/approachPartial least square (PLS) technique with the field survey of 148 participants was used for this analysis.FindingsThe empirical test results in the field setting show that attitude and supervisor influence positively affect goal commitment in the system implementation. Furthermore, LMX is a significant moderator between attitude and goal commitment within organizations, but this moderating effect is not valid in the relationship between supervisor influence and goal commitment since it is a more complex process influenced by variables other than supervisor influence.Originality/valueThe results showed that the model in this research has high explanatory and predictive power and is valuable in offering insights and guidance for implementers initiating technology-related changes within organizations.
A model of cultural intelligence and global identity
Authors: Randrianasolo Arilova , Semenov Alexey , Arnold Mark , Reynolds Kristy 
Published: August 2020

Purpose
This paper aims to propose an original model of cultural intelligence (CQ), global identity and consumer willingness to buy foreign products. Previous research has discussed the relationships between CQ and global identity but only in the context of multi-cultural management teams. The research presented here proposes a model that is applicable to consumer marketing.

Design/methodology/approach
Online surveys are used to collect data from the USA with a snowball sampling technique and from the UK with panel data. A structural equation model (SEM) is estimated in analysis of moment structures 25 and Hayes bootstrap mediation tests are used to test the hypotheses.

Findings
The SEM results show that global identity influences motivational CQ, motivational CQ influences cognitive, metacognitive and behavioral CQ and cognitive and behavioral CQ influence consumer willingness to buy foreign products. Results from Hayes Bootstrap mediation tests show that motivational CQ mediates the relationships between global identity and the other three CQ dimensions.

Practical implications
The findings imply that firms can gauge and enhance consumer CQ levels by investigating or influencing levels of global identity; managers can influence or gauge consumer metacognitive, cognitive and behavioral CQ through motivational CQ; and managers can target consumers with high cognitive and behavioral CQ levels when marketing foreign products.

Originality/value
This paper not only provides a deeper understanding of the relationships between global identity and cultural intelligence but also incorporates CQ in a consumer context. Previous research has only discussed CQ in the context of managers.
Macroprudential ring-fencing
Authors: Konečný Tomáš , Pfeifer Lukáš 
Published: August 2020

Purpose
This paper aims to focus on capital-related macroprudential policies in the context of recent policy discussions on the removal of barriers to the mobility of capital and liquidity of cross-border banks in the European Union (EU).

Design/methodology/approach
This study first discusses the link between financial stability and internal resource mobility of cross-border banks. Then, it examines past heterogeneity in structural capital buffers as key macroprudential capital instruments applied in the EU and relate them to costs of policy action, degree of foreign penetration and membership in the Banking Union.

Findings
Observed phase-in patterns of structural capital buffers in the EU are broadly consistent with costs of policy action, degree of foreign penetration and membership in the Banking Union as potential factors. The process of financial integration could be further enhanced through reduced uncertainty in the application of macroprudential policies that constrain capital mobility of cross-border banks.

Originality/value
This paper anchors macroprudential policies into a wider discussion on the mechanism and implications of ring-fencing in the EU over time. It discusses two policy areas, macroprudential policies and proposals for deeper financial integration, that share the same financial stability objective but tend to emphasize different implications of the mobility of capital and liquidity of cross-border banks in the EU. The study provides a discussion of potential implications of the recent adoption of the CRRII/CRDV legislation for future heterogeneity of macroprudential policies in the EU.
Does bruising influence the volatile profile of pears?
Authors: Bodner Martina , Scampicchio Matteo 
Published: August 2020

Purpose
Volatile flavor plays a main role in defining the fruit quality by consumers. Bruising leads often to dark spots on fruits and its amount could highly affect product quality. This paper aims to study the effect of bruising on the volatilome released by pears by using proton transfer reaction – mass spectrometry (PTR-MS).

Design/methodology/approach
Fingerprints of non-bruised and bruised pear samples were collected through PTR-MS for 28 days, and discriminant analysis was used to discriminate the fruit products. The CIELAB color changes were also measured during the entire ripening period.

Findings
Bruised pears released a higher intensity of volatile organic compounds (VOCs) compared to non-bruised pears (p16days = 0.049, p22days = 0.012, p28days = 0.006). In particular, the release of m/z 45 and m/z 47 were significantly (pm/z 45 = 0.076, pm/z 47 = 0.095.) higher in bruised samples, suggesting that the bruising event accelerated the natural ripening process. CIELAB color coordinates were also recorded. The coordinate a* showed a linear increase during the whole 28 days because of the loss of the green component. The CIELAB ΔE* was higher in the bruised pears than the non-bruised pears (p = 0.022).

Originality/value
Bruising can affect food quality and taste. Bruise susceptibility has been largely studied on apples, tomatoes and peaches, but rarely on pears. Very little is known about the effect of bruising on the volatilome of pears. Moreover, bruising research usually involved the study of physical properties; on the contrary, PTR-MS, applied to bruising research, has never been used before. Besides the analysis of volatilome, the changes in color were also recorded for the whole 28 days of analysis. The proposed method could be applied for the monitoring of pears quality in the food industry.
Risk of predation on offspring reduces parental provisioning, but not flight performance or survival across early life stages
Authors: Mouton James C. , Tobalske Bret W. , Wright Natalie A. , Martin Thomas E. 
Published: August 2020

Abstract

Developmental responses can help young animals reduce predation risk but can also yield costs to performance and survival in subsequent life stages with major implications for lifetime fitness. Compensatory mechanisms may evolve to offset such costs, but evidence from natural systems is largely lacking.

In songbirds, increased nest predation risk should favour reduced provisioning, but also young that fledge (leave their nest) at an earlier age. Both responses can result in fledglings with shorter wings, reduced mobility and decreased survival. Young may compensate for shorter wings developmentally by reallocating resources towards feather development or behaviourally by adjusting flight kinematics or habitat use. However, underfed young may lack the capacity to express these phenotypes due to insufficient resources or an inability to adjust allocation of resources.

Using predation risk experiments and 29 years of observational field data, we test whether increased nest predation risk reduces flight performance and survival during the fledgling stage and explore potential mechanisms that might underlie these effects. We show that young from high‐risk nests did not leave the nest earlier on average, but wing growth was slower likely due to observed reductions in parental feeding rates. Wings were shorter in high‐risk nests when fledglings left the nest early. Yet, fledglings from high‐risk nests showed improved flight performance for a given wing length such that flight performance at fledging did not differ between young from high‐risk and low‐risk nests. Young from high‐risk nests may have offset the costs of shorter wings on flight performance by accelerating the emergence of flight feathers from their sheaths to reduce wing porosity, though evidence for this mechanism was mixed. Fledglings from high‐risk nests also selected habitat with denser woody vegetation compared with young from low‐risk nests.

Together, these developmental and behavioural responses seem to mitigate the expected effects of increased nest predation risk on fledgling survival. Ultimately, our results show that offspring predation risk can affect parental provisioning and offspring morphology without major implications for performance and survival in subsequent life stages.

The relationship ageing of the population and saving in an unemployment context: Empirical evidence using an autoregressive distributed lag bounds testing approach
Authors: Frini Olfa 
Published: August 2020

AbstractIn this article, we emphasised that ageing population does not systematically depress savings by drawing attention to the factors that may distort that prediction of the life‐cycle hypothesis (LCH). To demonstrate it, we used two indicators for ageing: the total and aged dependency ratios and we looked at the economic context influence on national saving evolution through considering the labour market imbalance interference. By applying the autoregressive distributed lag approach, with Tunisian data during 1970–2018, a dynamic long‐run relationship between ageing and national saving is found, although it seemed to be sensitive to the used ageing indicator and the economic context. Indeed, the LCH is proved only by the total dependence ratio whereas the aged dependence ratio puts a significant long‐run upward pressure on saving. Further, in a context of unemployment without any benefit scheme, the LCH prediction cannot be endorsed by the two indicators. Hence, the social and economic conditions limit the LCH scope, bearing out that elderly not depress systematically savings. Therefore, to sustain saving major economic and financial reforms are needed, as to postpone the retirement age, to move from pay‐as‐you‐go system towards funded pension system, to promote life insurance and to diversify the long‐run savings products.
