The evolution of holiday system in China and its influence on domestic tourism demand
Authors: Shen Han , Wang Qiucheng , Ye Chuou , Liu Jessica Shihchi 
Published: October 2017

Purpose
The purpose of this paper is to focus on the reforms in the public-holiday-policy system and their influence on the domestic tourism in China. The major reforms in the Chinese holiday system in the last 20 years and the overall changes in the demand for domestic tourism are analyzed in this paper to provide a better understanding of China’s holiday-system reform for policy makers in the future.

Design/methodology/approach
This paper summarizes the development and reform of the holiday system in China. Policy review and domestic tourism statistics were applied to study the intrinsic relationship between the holiday system and the domestic tourism. The statistics of domestic tourism are cited, including the growth rates of both urban and rural tourists, the domestic tourism expenditure per capita, etc. Finally, this research explains the trends of these rates in a comprehensive background.

Findings
The increasing length of holidays positively affects the domestic tourism demand by increasing the leisure time. Yet, the holiday-tourism activities lead to a series of problems, such as a huge pressure on transportation, overloaded tourist attractions, and threats to safety precautions. Paid leave, price leverage, and more reasonable tourist-attraction arrangements will be effective in easing China’s holiday rush.

Originality/value
Through studying the intrinsic relationship between the holiday system and the domestic tourism, this paper points out the problems of excessive concentration of domestic tourism demand in a particular time, caused by the holiday system. Solutions and suggestions are provided on the basis of the analysis.
Managerial education and the wealth effect of corporate capital investment in Taiwan
Authors: Tseng Pi-Hsun , Su Xuan-Qi , Tsai Hsiu-Jung 
Published: October 2017

PurposeThe purpose of this paper is to study the effect of managerial education levels on the wealth effect at the time of investment announcements, by testing two competitive hypotheses: the agency theory-based overinvestment hypothesis vs the Q-theory-based organizational legitimacy hypothesis.Design/methodology/approachThe authors construct the sample by hand-collecting the announcement dates of capital investments from major newspapers published in Taiwan from 2006 to 2014. The authors then use the event study methodology to estimate cumulative abnormal returns at the time of investments announcements to measure the wealth effect. Finally, the authors examine the wealth effect for capital-investing firms with higher managerial education vs those with lower managerial education. The authors also conduct a cross-sectional regression to test the relation between the wealth effect of capital investment and managerial education.FindingsThe empirical results indicate that the wealth effect at the time of investment announcements is less favorable for firms with better-educated managers; this negative relation is mitigated for firms with higher institutional ownership and is aggravated for family-controlled firms; and the overall findings are supported by the agency theory-based overinvestment hypothesis, suggesting that higher managerial education lead to greater managerial optimism/overconfidence, which in turn increases the likelihood of overinvestment and implies a less favorable wealth effect associated with capital investment.Originality/valueThis study contributes to the literature by proposing a new, unexplored stock market’s reaction channel through which managerial education signals adverse information about potential overinvestment behavior, even though many studies suggests that managerial education serves as an indication of knowledge/capability and improves firm performance.
IPO overvaluation and returns prior to lockup expiration
Authors: Haggard K. Stephen , Xi Yaoyi 
Published: October 2017

Purpose
Conventional wisdom says that the price reduction stocks experience at expiration of the initial public offering (IPO) lockup period is due to relaxation of selling constraints. Findings from more recent literature question this explanation. The purpose of this paper is to examine a different cause for this price drop, IPO overvaluation.

Design/methodology/approach
Using the IPO overvaluation measures of Purnanandam and Swaminathan (2004), the authors examine IPO lockup period stock return differences between stocks in the highest and lowest overvaluation quintiles.

Findings
The authors show that the IPO lockup period price reduction is strongly related to overvaluation. Zero-investment portfolios long in the lowest overvaluation quintile and short in the highest overvaluation quintile of IPO firms have positive significant returns.

Practical implications
IPO investors can use the technique to identify firms likely to underperform in the IPO lockup period, potentially avoiding bad investments.

Originality/value
This is the first study to link IPO lockup period stock returns to IPO overvaluation, providing evidence on the impact of both overvaluation and short-selling constraints on stock returns in the IPO lockup period.
A novel tactile probe with medical and surgical applications
Authors: Afshari Elnaz , Sarkhosh Hadi , Najarian Siamak 
Published: October 2017

Purpose
The paper aims to discuss design, fabrication, testing and simulation of a novel tactile probe used for measuring the stiffness of biological soft tissues/materials with a view to medical and surgical applications.

Design/methodology/approach
Both finite element modeling and experimental approach were used in this research. The novel tactile probe capable of recording force-deformation feedback is accompanied with the tactile-status-display which is a custom-designed user-friendly interface. This system can evaluate the stiffness in each part of force-deformation status.

Findings
The new system named novel tactile probe was fabricated, and the results on artificial materials (with different stiffnesses) and the sheep kidney (containing a hard object) were reported. Recording different stiffnesses, detecting hard object embedded in soft tissue and predicting the exact location of it are the main results that have been extracted through the diagrams obtained by the novel tactile probe system.

Research limitations/implications
The designed and fabricated system can be modified and miniaturized to be used during different minimally invasive surgeries in the future.

Practical implications
The most distinguishing feature of this novel tactile probe is its applicability during different laparoscopic surgeries, so the in vivo data can be obtained.

Originality/value
For the first time, a tactile probe has been designed and tested in the form of laparoscopic instrument which upgrades the efficiency of available laparoscopic instruments. Also, the novel tactile probe can be used in both in vivo and in vitro experimental setups for measuring the stiffness of sensed objects.
Generalized eruptive keratoacanthoma with vitiligo followed by the development of prurigo nodularis: A case report and published work review
Authors: Xu Qianyue , Li Congying , Zhang Jia , Ling Bo , Yu Hong , Yao Zhirong 
Published: October 2017

AbstractHerein, we report a unique case of generalized eruptive keratoacanthoma (GEKA) in a 47‐year‐old Chinese man presenting with extensive pruritic papules and nodules accompanied by oral lesions. He also had a 2‐year history of vitiligo and long‐term experience of working outdoors. Biopsies were consistent with keratoacanthoma . Interestingly, prurigo nodularis (PN) was found in histopathology at 1‐year follow up. To our knowledge, this is the first report describing a case of GEKA with oral lesions complicated with vitiligo and developed with PN.

Published: October 2017

AbstractThe purpose of this work was to improve the oral bioavailability of a poorly soluble functional food ingredient, the total flavones of Hippophaë rhamnoides L. (TFH). A self‐microemulsion drug delivery system (SMEDDS) was developed to overcome the problems of poor absorption of TFH in vivo. The optimal SMEDDS significantly enhanced the solubility of TFH up to 530 times compared to that in water. The mean droplet size was 61.76 nm with uniform distribution. And the loaded system was stable at 25 °C for 3 mo with transparent appearance. The in vitro release of TFH from SMEDDS was faster and more complete than that from suspension. After oral administration of TFH–SMEDDS in rats, the relative bioavailability of TFH was dramatically improved for 3.09 times compared with the unencapsulated form. The investigation indicated the potential application of SMEDDS as a vehicle to improve the oral bioavailability of TFH.Practical ApplicationThe lipid‐based nanotechnology, namely self‐microemulsion drug delivery system (SMEDDS) was used to improve the bioavailability and oral delivery of total flavones of Hippophaë rhamnoides L. (TFH). The relevant bioavailability of TFH could be remarkably 3‐fold improved by the optimized SMEDDS. The SMEDDS produced via a simple one‐step process for poorly soluble TFH to achieve a significant improvement in the bioavailability, may endorse the promising utilization of TFH in functional foods as well as pharmaceutical fields with an enhanced absorption in vivo.
Scenario‐Based and Scenario‐Neutral Assessment of Climate Change Impacts on Operational Performance of a Multipurpose Reservoir

Published: October 2017

AbstractScenario‐based and scenario‐neutral impacts assessment approaches provide complementary information about how climate change‐driven effects on streamflow may change the operational performance of multipurpose dams. Examining a case study of Cougar Dam in Oregon, United States, we simulated current reservoir operations under scenarios of plausible future hydrology. Streamflow projections from the CGCM3.1 general circulation model for the A1B emission scenario were used to generate stochastic reservoir inflows that were then further perturbed to simulate a potentially drier future. These were then used to drive a simple reservoir model. In the scenario‐based analysis, we found reservoir operations are vulnerable to climate change. Increases in fall and winter inflow could lead to more frequent flood storage, reducing flexibility to store incoming flood flows. Uncertainty in spring inflow volume complicates projection of future filling performance. The reservoir may fill more or less often, depending on whether springs are wetter or drier. In the summer, drawdown may occur earlier to meet conservation objectives. From the scenario‐neutral analysis, we identified thresholds of streamflow magnitude that can predict climate change impacts for a wide range of scenarios. Our results highlight projected operational challenges for Cougar Dam and provide an example of how scenario‐based and scenario‐neutral approaches may be applied concurrently to assess climate change impacts.

Published: October 2017

AbstractWe describe the performance of a new metabarcoding approach to investigate the environmental diversity of a prominent group of widespread unicellular organisms, the Cercozoa. Cercozoa is an immensely large group of protists, and although it may dominate in soil and aquatic ecosystems, its environmental diversity remains undersampled. We designed PCR primers targeting the hypervariable region V4 of the small subunit ribosomal RNA (SSU or 18S) gene, which is the recommended barcode marker for Cercozoa. The length of the amplified fragment (c. 350 bp) is suitable for Illumina MiSeq, the most cost‐effective platform for molecular environmental surveys. We provide barcoded primers, an economical alternative to multiple libraries for multiplex sequencing of over a hundred samples. In silico, our primers matched 68% of the cercozoan sequences of the reference database and performed better than previously proposed new‐generation sequencing primers. In mountain grassland soils and in biological soil crusts from a variety of climatic regions, we were able to detect cercozoan sequences encompassing nearly the whole range of the phylum. We obtained 901 operational taxonomic units (OTUs) at 97% similarity threshold from 26 samples, with c. 50,000 sequences per site, and only 8% of noncercozoan sequences. We could report a further increase in the diversity of Cercozoa, as only 43% of the OTUs were 97%–100% similar to any known sequence. Our study thus provides an advanced tool for cercozoan metabarcoding and to investigate their diversity and distribution in the environment.
The Relation Between Walking and Language in Infant Siblings of Children With Autism Spectrum Disorder
Authors: West Kelsey L. , Leezenbaum Nina B. , Northrup Jessie B. , Iverson Jana M. 
Published: October 2017

In typical development, walk onset is accompanied by increased language growth (e.g., Walle & Campos, 2014). The present study explored whether this relation may be disrupted in the infant siblings of children with autism spectrum disorder (ASD; heightened risk of receiving an ASD diagnosis; HR), a population exhibiting substantial variability in motor and language development (e.g., Gamliel, Yirmiya, & Sigman, 2007; Landa & Garrett‐Mayer, 2006). Receptive and expressive language were examined across the transition to walking in three groups of HR infants (no diagnosis, language delay, and ASD; N = 91, 8–18 months) and in infants with no family history of ASD (N = 25; 9–15 months). Only infants with an eventual ASD diagnosis did not show increased language growth following walk onset.

Published: October 2017

AbstractAimPrevious studies have raised concerns that the use of anti‐tumour necrosis factor (anti‐TNF) therapy in patients with ulcerative colitis (UC) undergoing surgery may increase the risk of postoperative complications. We have taken a population‐based approach to investigate whether there is an association between anti‐TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy.MethodHospital Episode Statistics (HES) data and procedural coding were used to identify all patients in England between April 2006 and March 2015 undergoing subtotal colectomy for UC. Patients were grouped into those who received anti‐TNF therapy within 12 or 4 weeks of surgery and those who did not. The incidence of postoperative complications was evaluated by HES coding and compared between groups.ResultsIn all, 6225 UC patients underwent subtotal colectomy. 753 patients received anti‐TNF therapy within 12 weeks prior to surgery (418 within 4 weeks). There was no difference in postoperative complications between groups although groups were not comparable for age and comorbidities. Logistic regression with complications as the outcome variable did not show any significant association between anti‐TNF therapy and complications. Colectomy performed during an unplanned admission (vs planned admission) and smoking were associated with complications.ConclusionThis large population‐based study does not demonstrate any association between preoperative anti‐TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy. The only variables associated with complications were colectomy performed during an unplanned admission and smoking.

AbstractAimReconstruction with an ileosigmoidal anastomosis (ISA) or ileorectal anastomosis (IRA) is a surgical option after a subtotal colectomy. Anastomotic leakage (AL) is a problematic complication and high rates have been reported, but there is limited understanding of the risk factors involved. The aim of this study was to assess the established and potential predictors of AL following ISA and IRA.MethodThis was a retrospective cohort study including all patients who had undergone ISA or IRA at three Swedish referral centres for colorectal surgery between January 2007 and March 2015. Data regarding clinical characteristics, treatment and outcome were collected from medical records. Univariate and multivariate logistic regression models were used to determine the association between patient and treatment related factors and the cumulative incidence of AL.ResultsIn total, 227 patients were included. Overall, AL was detected amongst 30 patients (13.2%). Amongst patients undergoing colectomy with synchronous ISA or IRA (one‐stage procedure), AL occurred in 23 out of 120 (19.2%) compared with seven out of 107 (6.5%) after stoma reversal with ISA or IRA (two‐stage procedure) (P = 0.004). In addition, the multivariate analyses revealed a statistically significantly lower odds ratio for AL following a two‐stage procedure (OR 0.10, 95% CI 0.03–0.41, P = 0.001).ConclusionsThis study confirms high rates of AL following ISA and IRA. In particular, a synchronous procedure with colectomy and ISA/IRA carries a high risk of AL.
When Cars Hit Trucks and Girls Hug Boys: The Effect of Animacy on Word Order in Gestural Language Creation
Authors: Kocab Annemarie , Lam Hannah , Snedeker Jesse 
Published: October 2017

AbstractA well‐known typological observation is the dominance of subject‐initial word orders, SOV and SVO, across the world's languages. Recent findings from gestural language creation paradigms offer possible explanations for the prevalence of SOV. When asked to gesture transitive events with an animate agent and inanimate patient, gesturers tend to produce SOV order, regardless of their native language biases. Interestingly, when the patient is animate, gesturers shift away from SOV to use of other orders, like SVO and OSV. Two competing hypotheses have been proposed for this switch: the noisy channel account (Gibson et al., 2013) and the role conflict account (Hall, Mayberry, & Ferreira, 2013). We set out to distinguish between these two hypotheses, disentangling event reversibility and patient animacy, by looking at gestural sequences for events with two inanimate participants (inanimate‐inanimate, reversible). We replicated the previous findings of a preference for SOV order when describing animate‐inanimate, irreversible events as well as a decrease in the use of SOV when presented with animate‐animate, reversible events. Accompanying the drop in SOV, in a novel condition we observed an increase in the use of SVO and OSV orders when describing events involving two animate entities. In sum, we find that the observed avoidance of SOV order in gestural language creation paradigms when the event includes an animate agent and patient is driven by the animacy of the participants rather than the reversibility of the event. We suggest that findings from gestural creation paradigms are not automatically linkable to spoken language typology.
Below‐ground organic matter accumulation along a boreal forest fertility gradient relates to guild interaction within fungal communities
Authors: Kyaschenko Julia , Clemmensen Karina E. , Karltun Erik , Lindahl Björn D. 
Published: October 2017

AbstractPlant–soil interactions link ecosystem fertility and organic matter accumulation below ground. Soil microorganisms play a central role as mediators of these interactions, but mechanistic understanding is still largely lacking. Correlative data from a coniferous forest ecosystem support the hypothesis that interactions between fungal guilds play a central role in regulating organic matter accumulation in relation to fertility. With increasing ecosystem fertility, the proportion of saprotrophic basidiomycetes increased in deeper organic layers, at the expense of ectomycorrhizal fungal species. Saprotrophs correlated positively with the activity of oxidative enzymes, which in turn favoured organic matter turnover and nitrogen recycling to plants. Combined, our findings are consistent with a fungus‐mediated feedback loop, which results in a negative correlation between ecosystem fertility and below‐ground carbon storage. These findings call for a shift in focus from plant litter traits to fungal traits in explaining organic matter dynamics and ecosystem fertility in boreal forests.
Beyond “Lots of Hugs and Kisses”: Expressions of Parental Love From Parents and Their Young Children in Two‐Parent, Financially Stable Families

Published: October 2017

Given that parental love is essential for children's optimal development, the current study gathered examples of how parental love was demonstrated within parent–child relationships. Fifty‐eight two‐parent, financially stable families consisting of a mother, father, and young child (3–7 years old) from the Midwest were interviewed regarding how they demonstrated or perceived parental love. Results from an inductive thematic analysis revealed considerable variability in how parental love was demonstrated, with five themes emerging that overlapped between parents and their children: playing or doing activities together, demonstrating affection, creating structure, helping or supporting, and giving gifts or treats. Some gendered patterns among these themes were found with mothers emphasizing physical and verbal affection and fathers highlighting their more prominent role as playmates. The lay examples provided by parents and children in this exploratory study extend previous conceptualizations of parental love and underscore the importance of parents being attuned and responsive to the specific needs of their children.
