Examining the role of depression in the Filipino elderly’s food preferences in prison setting: data from conjoint analysis and SEM
Authors: de Guzman Allan , Barredo Sean Frances , Caillan Kim Rajah 
Published: March 2020

Purpose
Previous studies suggest that the care for elderly prisoners is a growing problem. The emerging phenomenon such as the correctional ageing crisis is an urgent concern that needs to be collectively and holistically addressed from a multi-sectoral perspective. In a developing country, like the Philippines, where prison congestion is alarming, the need for more empirical investigations that probe into the prison life and services is warranted to better inform penal policy and practice that would improve health outcomes among incarcerated individuals. The purpose of this study is to examine the extent to which depression among Filipino elderly prisoners shape their food choices.

Design/methodology/approach
A survey of 160 Filipino elderly prisoners of age 60 and above from October to November 2018 was conducted using a three-part research instrument, which consists of a personal and nutrition-related checklist, 15-point geriatric depression scale and a set of cards that were ranked and sorted through the balanced incomplete block design.

Findings
Results of the survey were subjected to conjoint analysis and structural equation modeling using the Statistical Package for the Social Sciences 24. Interestingly, taste was the most considered attribute (30.765%) while portion size (9.759%) is the least considered by the Filipino elderly prisoners. Notably, depression has a significant positive effect on their food preferences in all attributes except portion size.

Research limitations/implications
This study was limited to two prison settings in the Philippines. Considering the results from the conjoint analysis, strategies can be developed in designing an individualized meal plan suitable for the needs of each elderly prisoner. Also, sizeable government appropriations should be in place to ensure the nutritional quality of food served to aging Filipino prisoners.

Practical implications
Provisions for a pool of nutritionists working hand in hand with other health members would guarantee a prison system that promotes the overall well-being of each prisoner. Further, this study can contribute valuable inputs in the menu cycle practice of prisons in the country. There may be a need to prioritize the nutritional aspect of these vulnerable and deprived groups so as to promote a better quality of life among elderly prisoners. Also, other forms of psychosocial, physical and spiritual health activities extended to elderly prisoners may prevent depressive symptoms.

Originality/value
Conjoint analysis is remarkably gaining prominence in not only the health-care setting (Phillips et al., 2002; Ryan and Farrar, 2000) but also the field of nutrition. It holds a number of unique and practical promises to prison settings.
Universities speak up regarding the implementation of sustainable development challenges
Authors: Farinha Carla Sofia , Caeiro Sandra Sofia , Azeiteiro Ulisses 
Published: March 2020

Purpose
This study aims to expand knowledge and provide further insights on how education for sustainable development (ESD) has been integrated into programmes at higher education institutions (HEIs) in Portugal.

Design/methodology/approach
A questionnaire survey was given to key actors in charge of sustainability implementation at each Portuguese public university. Semi-structured interviews were also conducted with 13 of the survey respondents and the data were analysed.

Findings
Results showed that Portuguese public universities have their own strategies and policies on ESD, leading them to introduce initiatives arising from their proactiveness rather than governmental edicts. Some universities implemented ESD planning and beneficial “green” practices such as waste separation and recycling and ways to reduce energy consumption that can be a result of the improvement after the United Nations Decade 2005-2014. However, these actions seem to have been taken in isolation and not holistically integrated. Universities face many barriers including lack of funding, not properly trained people and inept government policies. They also must overcome challenges in implementing ESD.

Research limitations/implications
This research into the implementation of ESD has a national scope; the findings should be interpreted only in a Portuguese university context despite the high number of interviewees.

Practical implications
The study has increased knowledge, provided further insights on how ESD has been integrated at HEIs and provided examples of integrated practices at Portuguese universities. A Sustainability4U platform was proposed for enhancing awareness of the need for increasing sustainable development.

Originality/value
This study contributes to defining a country’s profile and how to implement sustainability in HEIs. The importance of obtaining information from key actors in sustainability at Portuguese public universities was highlighted.
Determining wine relevant markets
Authors: Romero-Gómez Exequiel , Ferro Gustavo 
Published: March 2020

Purpose
This study aims to verify how the product-relevant market for wines should be defined. To do so, the authors apply an empirical methodology to determine the levels of substitution among wine-categories, identifying each relevant market in Argentina.

Design/methodology/approach
The authors perform an econometric analysis applying the nested logit methodology that will enable us to estimate cross elasticities in wine segments in the Argentine market. The database contains 1,367 brands and a maximum of 395 firms offering products of different segments. If cross elasticities between wine segments are positive and significantly different to zero, the products belong to the same relevant market. In the methodological section, the authors discuss the pros and cons of this approach and its alternatives, while in the empirical analysis, they perform several robustness controls.

Findings
The proposed method and results provide an alternative to exogenously defining where each product category begins and ends. The results show that the relevant market for wines should be segmented by categories as the substitution between each one is very low.

Research limitations/implications
In this empirical work, the study analyzes whether each segment constitutes a relevant, independent market. In Argentina, the practice of competition policy does not recognize substitution between different categories of wine; thus, each category constitutes a relevant market by itself, while according to the international practice, the relevant market includes all wine categories. The results suggest exploring the existence of different relevant markets of wine.

Practical implications
Under the label “wine,” different types or qualities can act as substitutes among them in different possible relevant markets. A more precise definition of relevant markets permits informed decisions facing proposed mergers or anticompetitive practices.

Social implications
This study provides a mechanism to determine the levels of substitution among wine categories (i.e. to find the boundaries of each relevant market). Wine is a differentiated product and, as such, offers different qualities (categories) for consumers. The consideration of those differences in winery mergers has consequences on social welfare.

Originality/value
According to the international practice in competition policy, the relevant market includes all wine categories. This study provides an alternative to defining exogenously where each category of product begins and ends and does not assume a priori the direction or intensity of substitution among products.
Tribological behaviors of water-based drilling mud with oleic acid-filled microcapsules as lubricant additives for steel-steel contact
Authors: Ji Min , Liu Shuhai , Xiao Huaping 
Published: March 2020

Purpose
The purpose of this paper is to study the tribology behavior of steel–steel contact under the lubrication of water-based drilling mud with different oleic acid-filled microcapsules as lubricant additives.

Design/methodology/approach
A ball-on-disc tribometer was used to evaluate the lubrication properties of the steel–steel contact. The wear tracks of the worn surfaces were observed by a scanning electron microscope.

Findings
Results show that the dependence of both friction and wear on the category of additives shares a consistent pattern. In contrast to oleic acid and empty microcapsules, oleic acid-filled microcapsules achieve the best tribological performance which is related to the lubricant effect of oleic acid and the isolation and rolling abilities of microcapsules.

Practical implications
This study provides a helpful method of encapsulated lubricant additives to prolong lubrication performance for steel–steel contact.

Originality/value
This study has applied microcapsules to improve the tribological properties of drilling mud.

Applying big data to guide firms’ future industrial marketing strategies
Authors: Gnizy Itzhak 
Published: March 2020

Purpose
While big data (BD), a transformative emerging phenomenon on its youth, plays a growing role in organizations in improving marketing decision-making, few academic works examine the mechanism through which BD can be applied to guide future competitive advantage strategies. The purpose of this paper is to examine if BD’s predictive power helps business to business (B2B) firms selecting their intended generic (differentiation, focus, and cost leadership) strategies.

Design/methodology/approach
Drawing on the learning theory, the study proposes the use of BD as a key driver of intended strategies. Based on data from a cross-industry sample of executives, a conceptual model is tested using path and robustness analyses.

Findings
The use of BD plays a prominent role in the selection of intended future strategies in industrial markets. Additional tests demonstrate conditions of competitive intensity and strategic flexibility where BD is more and less beneficial.

Research limitations/implications
The study furthers the understanding of traditional learning and intelligence use frameworks and of contemporary future strategies drivers.

Practical implications
BD availability enables managers leveraging knowledge embedded in data-rich systems to gain predictive insights that help in guiding new strategic directions to maintain competitive advantage.

Originality/value
The study reinforces the continued applicability of Porter’s generic positioning strategies in the digital era. It addresses the paucity of research on BD in B2B context and is the first to provide theoretical and practical reflections on how BD utilization influences industrial intended strategies. The study strengthens contemporary managerial views defending that data drive strategies rather than the opposite.

Authors: Yang Naiding , Song Yue , Zhang Yanlu , Wang Jingbei 
Published: March 2020

PurposeThe purpose of this study is to enhance the comprehensive understanding of the roles of resource investments, explicit contracts and three components ofguanxi(i.e.renqing,ganqingandmianzi) in asymmetric research and development (R&D) partnerships. Treating dependence asymmetry as a multidimensional construct, this study examines the moderating effects of these elements on the relationships between resources and information asymmetry and opportunism.Design/methodology/approachThe study was executed by issuing questionnaires to R&D managers participating in R&D projects and collaborations in the Shanghai and Jiangsu provinces via e-mail and face to face surveys. A multiple regression analysis was used to test the hypotheses.FindingsThe empirical test generally supported the conceptual model and produced the following findings: first, resources and information asymmetry significantly and positively affect opportunism. Second, the partner’s resource investments can weaken the effect of resources and information asymmetry on the partner’s opportunism. Third, explicit contracts can reduce the impact of information asymmetry on the partner’s opportunism. Fourth,renqingandganqingbut notmianzican weaken the influence of information asymmetry on the partner’s opportunism.Originality/valueThis study provides a comprehensive and clear understanding of how opportunism can be curbed by jointly considering resource investments, explicit contracts andguanxiin asymmetric R&D cooperative relationships. Moreover, dependence asymmetry andguanxiare measured as a multidimensional construct and reveal their underlying structure, which expands previous understandings of risk management in R&D collaborations.
Open strategy: role of organizational democracy
Authors: Adobor Henry 
Published: March 2020

PurposeA core premise of the paper is that participative, democratic organizational forms have a direct effect on openness. A key proposition is that organizational forms that promote inclusion, transparency and shared decision-making more broadly as part of their structure and culture would enhance greater openness. However, democratic forms are not a panacea when it comes to openness, there are inherent paradoxes, leading to inevitable tradeoffs that democratic organizations must manage.Design/methodology/approachThe theoretical framework in the study explores the interaction between open strategy making and organizational democracy. This paper reviews the literature on open strategy and organizational democracy and presents propositions linking openness and elements of democratic organizations.FindingsOpen strategy requires a level of inclusion and transparency not typically associated with hierarchical organizations. This paper proposed that an organizational context where there are institutionalized processes that promote both transparency and inclusiveness, shared decision-making and a supportive organizational culture would promote openness. At the same time, these organizations need to manage key paradoxes associated with organizational democracy to benefit from its positive effect on openness. The idea is not that hierarchies cannot be open; they may simply need to be more creative and work harder at providing the scaffolding for participation.Research limitations/implicationsThis is a conceptual paper and we cannot make any claims of causality. It is also possible to refine the framework by adding or eliminating some of the conceptual variables.Practical implicationsOpening up the strategy process to non-traditional stakeholders can improve the strategy formation process. Non-traditional stakeholders can bring new insight, and be motivated and prepared for strategy implementation when they are part of the strategy formation process. Organizations need to focus on creating a climate that supports openness by emphasizing structural forms that promote openness. Sharing decision-making, profits and creating a democratic culture are important for successful openness. In addition, organizations need to manage the tradeoffs that arise as they link organizational democracy to openness.Originality/valueThis paper discusses the link between open strategy and organizational democracy. The research sheds light on how organizational forms, specifically structure affects openness, as well as the limits to structure and openness.
Customer concentration types and public debt contracts
Authors: Na HyunJun 
Published: March 2020

Purpose
This paper aims to examine how a firm’s customer concentration, which is the amount of sales between a supplier firm and the major customers, affects corporate bond contracts. This study also investigates how the types of customer concentration have a significant impact on bond contracts.

Design/methodology/approach
The research uses the Compustat’s segment customer database and the Mergent fixed income securities database, which provides details about publicly offered US bond issues and issuers. The sample also includes the US Congressional committees’ data from the 96th to 115th congresses. To control any endogenous concerns, the author uses changes in the seniority of US senators on powerful committees and the American Recovery and Reinvestment Act of 2009 (ARRA) as exogenous shocks. For a robustness test, the author also uses the propensity score-matched pairs.

Findings
While higher customer concentration, on average, leads to higher yield spreads and strict covenants, firms that have the US Government as a major customer pay lower yield spreads and have higher issue ratings. However, as a firm’s sales depend too heavily on the US Government customer channel, the bond issuance is likely to have lower issue ratings. The main findings also show that firms with government concentrations take advantage of political links, leading to lower yield spreads after two exogenous events.

Originality/value
The findings in this paper show the importance of a firm’s customer types in bond markets by emphasizing the positive impact of the US Government as the sales channel. Exogenous event studies based on the propensity-matched sample alleviate the endogenous concerns.

The value was in demonstrating that there are a wide variety of strategies businesses can use to improve engagement, using technology as well as traditional methods to ensure they reach all members of staff.
Different impacts of pMP19 on the virulence of Melissococcus plutonius strains with different genetic backgrounds
Authors: Nakamura Keiko , Okumura Kayo , Harada Mariko , Okamoto Mariko , Okura Masatoshi , Takamatsu Daisuke 
Published: March 2020

SummaryVirulence factors responsible for bacterial pathogenicity are often encoded by plasmids. In Melissococcus plutonius, the causative agent of European foulbrood of honey bees, a putative virulence plasmid (pMP19) possessing mtxA, which encodes a putative insecticidal toxin, was found by comparative genome analyses. However, as the role of pMP19 in the pathogenesis of European foulbrood remains to be elucidated, we generated pMP19 cured‐M. plutonius from representative strains of the three genetically distinct groups (CC3, CC12 and CC13) and compared their virulence against Apis mellifera larvae using our in vitro infection model. Under the conditions tested, the loss of pMP19 abrogated the pathogenicity in CC3 strains, and > 94% of pMP19‐cured CC3 strain‐infected larvae became adult bees, suggesting that pMP19 is a virulence determinant of CC3 strains. However, introduction of mtxA on its own did not increase the virulence of pMP19‐cured strains. In contrast to CC3 strains, the representative CC12 strain remained virulent even in the absence of pMP19, whereas the representative CC13 strain was avirulent even in the presence of the plasmid. Thus, pMP19 plays a role in the virulence of M. plutonius; however, its impact on the virulence varies among strains with different genetic backgrounds.

Authors: Wang Jun , Yao Shupeng , Diao Yanping , Geng Yan , Bi Yanling , Liu Guangyue 
Published: March 2020

BackgroundLung adenocarcinoma (LUAD) is a subtype of lung cancer (LC), which is the most common tumor worldwide. Accumulating evidence has elucidated an important role of microRNAs (miRNAs) in mediating the development and progression of several tumors. The purpose of this study was to explore the role and underlying mechanism of miR‐15b in LUAD.MethodsCCK‐8 and Transwell assays were conducted to measure the capacities of cell viability and migration in SPC‐A1 cells. Luciferase assay was utilized to verifymiR‐15b direct binding to BCL2 mRNA 3′‐UTR.ResultsWe determined that miR‐15b was overexpressed in LUAD and miR‐15b overexpression predicted a significantly worse outcome in patients with LUAD. miR‐15b improved LUAD growth in vitro and vivo. miR‐15b enhanced cell migration and epithelial–mesenchymal transition (EMT) in LUAD. miR‐15b promoted cell viability, migration and EMT through inhibiting BCL2 expression by targeting to its mRNA 3′‐UTR. BCL2 reversed functions of miR‐15b on promoting cell proliferation, migration and EMT in SPC‐A1 cells.ConclusionsmiR‐15b promoted cell viability, migration and EMT by targeting BCL2 in LUAD. The newly identified miR‐15b/BCL2 axis provides a novel insight into the pathogenesis of LUAD.
Lung cancer in patients with and without rheumatoid arthritis: A propensity score‐matched survival analysis cohort study
Authors: Zhang Lei , Zhao Qiliang , Yuan Fan , Liu Min 
Published: March 2020

BackgroundConnective tissue disease increases the risk of lung cancer, but whether rheumatoid arthritis (RA) has an effect on the overall survival (OS) rate in this population has not been well studied.MethodsPatients diagnosed with lung cancer between January 2015 and December 2017 were enrolled in this retrospective analysis. Propensity score matching was performed to balance the baseline of the two groups, whereas the differences between patients with and without RA were compared using survival analysis. Further, the effects of interstitial lung disease (ILD) and qi deficiency on survival in cases of RA with lung cancer were examined. Cox regression analysis was applied to predict the factors that influenced the survival of lung cancer to one year.ResultsOverall, 154 lung cancer patients, including 136 (88.3%) without RA and 18 (11.7%) with RA, were included. Two comparison cohorts were matched by 1:2 propensity score matching, which yielded 18 lung cancer patients with RA and 36 lung cancer patients without RA. Ultimately, the survival prognosis of lung cancer and RA was worse than that without RA, that of patients with ILD with RA and lung cancer was worse than that among those without RA, and that of patients with qi deficiency with RA and lung cancer was worse than that among those without RA.ConclusionsThe survival prognosis of lung cancer patients with RA is worse than that of those without RA. ILD and qi deficiency promote reduced survival when found in conjunction with RA in patients with lung cancer.
