The illusion of technique: sustained enterprise innovation as an aspirational problem
Authors: Duening Thomas 
Published: June 2018

Purpose
This paper is based on insights from philosophy of science, centered in Gilbert Ryle’s notion of “category mistakes”. A category mistake occurs in a science when scholars have been thinking of a phenomenon as of a certain sort, when it is really nothing of the kind. This paper aims to claim that regarding sustained enterprise innovation (SEI) as a strictly operational problem commits such a category mistake. Instead, SEI is an aspirational problem and thus requires scholars to examine it from that perspective as well.

Design/methodology/approach
This paper begins by explicating Ryle’s notion of a category mistake. It develops the suggestion that innovation scholars have made such a mistake by thinking of innovation as a strictly operational problem. In reality, it is as much an aspirational problem. The paper then builds on the metaphor made famous by Isaiah Berlin, distinguishing between hedgehogs and foxes. A hedgehog is a leader who copes with the non-predictive nature of innovation. The paper builds on the findings from positive psychology and virtue epistemology to highlight how humans can act rationally in the face of non-predictive outcomes. Four virtues of hedgehog leadership are proposed and defined.

Findings
The paper concludes that hedgehog leadership is necessary for sustained enterprise innovation. It also concludes that hedgehogs can act rationally in pursuit of non-predictive outcomes by practicing a set of governing virtues.

Research limitations/implications
Further research needs to be conducted to validate the proposed governing virtues, to illuminate the optimal hedgehog/fox balance within the enterprise, and to validate through longitudinal work the impact of hedgehogs on sustained enterprise innovation.

Practical implications
Based on the continuing interest in innovation expressed by enterprise leaders around the world, hedgehogs are in increasing demand. Fortunately, hedgehogs can be made (and self-made) via deliberate practice of the governing virtues. Aspiring and current hedgehogs can be confident that practicing these virtues and becoming increasingly adept at their application will promote and effect enterprise innovation.

Originality/value
Very little research has been conducted on the aspirational aspect of SEI. This is an insidious gap in the literature, as it affects scholars and practitioners alike. Scholars are trapped in the “normal science” paradigm that treats the innovation problem as if it can be solved through operational techniques. This paper contends that this ubiquitous category mistake has led scholars down a blind alley. Instead, it is important for scholars and practitioners alike to view SEI as an aspirational problem that requires vastly different research frameworks and practitioner prescriptions.

Authors: Liu Jinliang , Jia Yanmin , Zhang Guanhua , Wang Jiawei 
Published: June 2018

Purpose
In the freeze-thaw zone, the pre-stressed concrete of bridge structure will be damaged by freezing-thawing, the bearing capacity of structure will decrease and the safety will be affected. The purpose of this paper is to establish the time-dependent resistance degradation model of structure in the freeze-thaw zone, and analysis the structural reliability and remaining service life in different freeze-thaw zones.

Design/methodology/approach
First, according to the theory of structural design, a calculation model of the resistance of pre-stressed concrete structures in f freeze-thaw zone is established. Second, the time-dependent resistance model was verified by the test beam bending failure test results done by the research group, which has been in service for 20 years in freeze-thaw zone. Third, using JC algorithm in MATLAB to calculate the index on the reliability of pre-stressed concrete structure in frozen thawed zones, forecasting the s remaining service life of structure.

Findings
First, the calculation model of the resistance of pre-stressed concrete structures in freeze-thaw zone is accurate and it has excellent applicability. Second, the structural resistance deterioration time in Wet-Warm-Frozen Zone is the earliest. Third, once the pre-stressed reinforcement rusts, the structural reliability index will reach limit value quickly. Finally, the remaining service life of structure meets the designed expectation value only in a few of freeze-thaw zones in China.

Originality/value
The research will provide a reference for the design on the durability of a pre-stressed concrete structure in the freeze-thaw zone. In order to verify the security of pre-stressed concrete structures in the freeze-thaw zone, engineers can use the model presented in this paper for durability checking, it has an important significance.
Mesh sensitivity analysis on implicit and explicit method for rolling simulation
Authors: Gavalas Evangelos , Pressas Ioannis , Papaefthymiou Spyros 
Published: June 2018

Purpose
The purpose of this paper is to compare the performance of implicit and explicit integration schemes for simulating the metal rolling process using commercial software packages ANSYS™ and LS-DYNA™.

Design/methodology/approach
For the industrial application of finite element method, the time discretization is one of the most important factors that determine the stability and efficiency of the analysis. An iterative approach, which is unconditionally stable in linear analyses, is the obvious choice for a quasi-static problem such as metal rolling. However, this approach may be challenging in achieving convergence with non-linear material behavior and complicated contact conditions. Therefore, a non-iterative method is usually adopted, in order to achieve computational accuracy through very small time steps. Models using both methods were constructed and compared for computational efficiency.

Findings
The results indicate that the explicit method yields higher levels of efficiency compared to the implicit method as model complexity increases. Furthermore, the implicit method displayed instabilities and numerical difficulties in certain load conditions further disfavoring the solver’s performance.

Originality/value
Comparison of the implicit and explicit procedures for time stepping was applied in 3D finite element analysis of the plate rolling process in order to evaluate and quantify the computational efficiency.

Published: June 2018

PurposeThe purpose of this paper is to investigate the fracture properties of hybrid woven bamboo (WB)/woven e-glass (EG) fiber composites with various layer arrangements. This paper utilized a specific type of bamboo species namedGigantochloa Scortechinii(Buluh Semantan).Design/methodology/approachIn these experiments, unsaturated polyester, woven EG and WB fibers were prepared through the hand lay-up technique. The composite bamboo strips were prepared in 1.5 mm thickness. The strips are woven to make a single layer. The layer was then laminated into several thicknesses. The specimens were then characterized using compact tension fracture tests.FindingsThe fracture toughness of 12–14 MPa was obtained. These findings suggest that this hybrid bamboo composite provides superior fracture strength that is equivalent with steel alloy and is extremely a good alternative for reinforcing fibers to combat fracture failures of materials and structures.Originality/valueIn this paper, experimental determination of newly developed composite made of WB and woven EG is presented.
Culture, consent and confidentiality in workplace autoethnography
Authors: Lee Catherine 
Published: June 2018

PurposeThe purpose of this paper is to examine the author’s experiences as a school teacher and a lesbian. It considers the culture and discourses of power in the school and the ethical implications of telling the author’s story. Utilizing autoethnography as a method of inquiry, it draws on a critical incident to explore the incompatibility of the author’s private and professional identities, and reflect on the impact of homophobic and heteronormative discursive practices in the workplace, on health, well-being and identity.Design/methodology/approachThis research is grounded in an interpretivist philosophy. It utilizes writing about the self as a method of inquiry.FindingsThis research examines the incompatibility of the author’s private and professional identities and offers insight into the steps that those in positions of power will take to protect and perpetuate the heteronormative discourse of rural life.Research limitations/implicationsThis research presents the perspective of only one lesbian teacher in a rural context. Consequently, generalizations are inappropriate and recommendations are difficult. Whilst the absence of clear ethical regulation presents an infinite number of possibilities for autoethnographers, the silence that surrounds the prescription of the ethics of autoethnography leaves those of us at the beginnings of our research careers without clear guidance.Originality/valueThis research specifically addresses a dearth of research examining the experiences of the rural lesbian (or gay) teacher in the UK. Headteachers of rural schools must ensure that their schools are inclusive and welcoming environments for teachers, and their equalities policies are living documents that are not simply cast aside in the face of rural parent power. Young people in the countryside deserve access to the full pool of teaching talent and should have access to the diverse role models that their urban and suburban counterparts are beginning to enjoy.
Implementation and evaluation of online, synchronous research consultations for graduate students
Authors: Bezet Amanda , Duncan Taylor , Litvin Kira 
Published: June 2018

Purpose
Librarians at Northcentral University (NCU) provide online synchronous research consultations for students to discuss resources and search strategies for class assignments, papers, presentations, theses and dissertations. The purpose of this paper is to document the implementation and assessment of this service and to seek to demonstrate that research consultations provided by NCU librarians contribute to students’ learning and success.

Design/methodology/approach
Research consultations are scheduled using Springshare LibCal and are conducted via Citrix GoToMeeting. Students report their satisfaction and skills learned via the Research Consultation Satisfaction Survey. Dissertation chairs and faculty instructors complete separate surveys, which assess the effect that research consultations had on their students’ work. All surveys were created using Qualtrics.

Findings
Assessment data reveal that students are satisfied with the research consultation service and can identify specific skills learned. Additionally, faculty and dissertation chairs report an improvement in students’ citations and ability to locate relevant sources. Future research may include examination of learning analytics or citation analysis for students who participated in research consultations.

Originality/value
Research consultations are rarely documented in the scholarly literature. An opportunity exists to make virtual research consultations more widely adopted as a distinct library reference service, and further, to measure the impact of this service. This project demonstrates how to successfully implement and assess online research consultations. Techniques discussed may be used in 100 per cent virtual environments, as well as within traditional, brick and mortar schools that may already offer face-to-face research consultations.
Portfolio construction and risk management: theory versus practice
Authors: Lee Stefan Colza , Eid Junior William 
Published: June 2018

Purpose
This paper aims to identify a possible mismatch between the theory found in academic research and the practices of investment managers in Brazil.

Design/methodology/approach
The chosen approach is a field survey. This paper considers 78 survey responses from 274 asset management companies. Data obtained are analyzed using independence tests between two variables and multiple regressions.

Findings
The results show that most Brazilian investment managers have not adopted current best practices recommended by the financial academic literature and that there is a significant gap between academic recommendations and asset management practices. The modern portfolio theory is still more widely used than the post-modern portfolio theory, and quantitative portfolio optimization is less often used than the simple rule of defining a maximum concentration limit for any single asset. Moreover, the results show that the normal distribution is used more than parametrical distributions with asymmetry and kurtosis to estimate value at risk, among other findings.

Originality/value
This study may be considered a pioneering work in portfolio construction, risk management and performance evaluation in Brazil. Although academia in Brazil and abroad has thoroughly researched portfolio construction, risk management and performance evaluation, little is known about the actual implementation and utilization of this research by Brazilian practitioners.

Authors: Guimaraes Tomas Aquino , Gomes Adalmir Oliveira , Guarido Filho Edson Ronaldo 
Published: June 2018

Purpose
The purpose of this paper is to discuss the concept of Administration of Justice as a research field and set out an agenda for future studies that could promote the production of scientific knowledge in this area.

Design/methodology/approach
This paper explores the idiosyncratic features, dimensions of analysis upon the Administration of Justice, states a research agenda and discusses the main challenges on this theme. This paper conceptualizes Administration of Justice as a research field and discusses related phenomena from institutional and economic perspectives on innovation, performance, governance and legitimacy.

Findings
As a research field, Administration of Justice is defined as a set of theoretical concepts, research methods and techniques, aiming to investigate the management processes associated with the use and articulation of resources, knowledge and institutions, at different levels of the justice system, and their influence on the provision of justice in a given social context. As social phenomena, four levels of analysis are proper to investigate the justice system: societal, inter-organizational, organizational and operational. Innovation, performance, governance and legitimacy are central themes of the Administration of Justice and present various gaps and research opportunities.

Research limitations/implications
The main implications is the proposal of an agenda for future studies on the Administration of Justice field, which is an important step in raising awareness of the issue.

Originality/value
Administration of Justice encompasses a growing interest among academics, justice practitioners and public managers regarding managerial and political practices carried out in the justice system. Although relevant, this subject has been scarcely studied by the management community. This paper invites community to adopt an organizational and institutional perspective to Administration of Justice, setting an agenda for future research.
Mother knows best: exploring the matrilineal influence in family tourism among Filipinos living in New Zealand
Authors: Capistrano Robert Charles , Bernardo Maria Aurora Correa 
Published: June 2018

PurposeThis paper aims to examine the personal meanings of hosting experiences of first-generation immigrant families, particularly Filipino mothers in New Zealand, with their visiting relatives (VRs) from the Philippines by using the conceptual lens of hospitality.Design/methodology/approachThrough a qualitative approach, a multi-sited fieldwork was carried out to examine kinship ties that bind immigrant-host families in New Zealand with their VRs from the Philippines. Results of in-depth interviews of immigrant-host mothers on their recollections of family visits were thematically analysed.FindingsThe main drivers that shape the hosting experiences of the research participants are modelling filial piety, fulfilling cultural expectations and strengthening family bonds. These main drivers enable sustaining intergenerational ties that unite the mother’s families in the Philippines and those in New Zealand.Research limitations/implicationsThe study elucidates the complex dynamics of culturally connected and motivated domestic hospitality, where the mother is the main protagonist and orchestrator. This dominance is often subdued, and thus, marketing for family often misses the mark. While the study has a small sample size and therefore lacks representativeness, qualitative accounts have produced an enriched cognitive schema that would enable an interesting way of examining the phenomenon.Practical implicationsThis study reveals that matrilineal influence on family tourism among migrant Filipinos in New Zealand is strong and culturally influenced. Further studies may be done with families from other cultures and families. From a practical perspective, the findings suggest the importance of marketing tourism or hospitality products that facilitate visiting friends and relatives’ travel through domestic hospitality.Social implicationsThis research calls for reforms in the way family tourism is marketed. While commercial imperatives did not drive this research, findings indicate that certain cultures adhere to the wisdom of mothers on making the final decision on how hospitality has to be extended and manifested.Originality/valueIn the context of family tourism, inadequate research has been undertaken to examine the perspectives of women and their role as host in the travel of VFR. This study purports to fill in the gap in literature related to hosting experiences of women in the context of family tourism and VFR travel and to consider the voices of women in their new homeland.

Published: June 2018

SummaryA genome‐wide association study (GWAS) was conducted for two carcass traits in Chinese Simmental beef cattle. The experimental population consisted of 1301 individuals genotyped with the Illumina BovineHD SNP BeadChip (770K). After quality control, 671 990 SNPs and 1217 individuals were retained for the GWAS. The phenotypic traits included carcass weight and bone weight, which were measured after the cattle were slaughtered at 16 to 18 months of age. Three statistical models—a fixed polygene model, a random polygene model and a composite interval mapping polygene model—were used for the GWAS. The genome‐wide significance threshold after Bonferroni correction was 7.44E‐08 (= 0.05/671 990). In this study, we detected eight and seven SNPs significantly associated with carcass weight and bone weight respectively. In total, 11 candidate genes were identified within or close to these significant SNPs. Of these, we found several novel candidate genes, including PBX1, GCNT4, ALDH1A2, LCORL and WDFY3, to be associated with carcass weight and bone weight in Chinese Simmental beef cattle, and their functional roles need to be verified in further studies.

Authors: Bean M. K. , Ingersoll K. S. , Powell P. , Stern M. , Evans R. K. , Wickham E. P. , Mazzeo S. E. 
Published: June 2018

SummaryThe aim of this study is to examine outcomes from MI Values, a motivational interviewing (MI) intervention implemented adjunctive to obesity treatment. Adolescents (n = 99; 73% African American; 74% female; mean body mass index [BMI] percentile = 98.9 ± 1.2) were randomized to receive two MI sessions or education control. All adolescents participated in structured behavioural weight management treatment. Baseline, 3‐ and 6‐month assessments of anthropometrics, dietary intake and physical activity were obtained. Both groups had significant reductions in BMI z‐scores and energy intake and increased physical activity at 3 and 6 months (P < 0.05). MI participants reported greater reductions in 3‐month energy intake compared with controls. Participation in MI is associated with reduction in energy intake, consistent with better adherence to dietitian visits previously reported from MI Values. MI might be an effective adjunct to adolescent obesity treatment; future research is needed to determine if motivational interviewing can enhance BMI outcomes, via greater adherence to behavioural intervention.

Published: June 2018

AbstractBackgroundIn COPD, weight loss and muscle wasting contribute significantly to morbidity, disability, and handicap. Dominant‐handgrip strength for evaluation of muscle strength has not been tested as a parameter to predict outcome of weaning from mechanical ventilation (MV).ObjectivesTo evaluate the association between handgrip strength and the duration and success of weaning and extubation outcome.Materials and methodsThis prospective study included 34 COPD patients requiring MV for at least 48 hours. Recovery from sedation and muscle relaxants was assessed before recruitment. Serial meseaurment of handgrip strength were assessed by trained personnel.ResultsThere was a significant negative correlation between baseline hand grip and duration of MV (P = .047, r = −.343). The mean day 5 hand grip was significantly lower in person who died compared to survivors (5.7 ± 5.5 vs 18.2 ± 14.5, P = .044). The mean day 5 hand grip was significantly lower in patients who needed reintubation compared to those in patients who did not need reintubation (2.8 ± 2 vs 17.2 ± 13.9, P = .029). There was no significant difference in the mean baseline, day 2, day 3, day 4 and day 5 hand grip in weaning success compared to those in failure (P > .05).ConclusionHandgrip strength may be good predictor for duration of MV, extubation outcome, ICU mortality and prognosis.
