Abstract

Purpose

To improve the frequency of adoption of mobile health services (MHSs) by users (consumers), it is critical to understand users' MHS adoption behaviors. However, the literature primarily focuses on MHS adoption-related factors and lacks consideration of the joint impacts of reasons for (RF) and reasons against (RA) on users' attitudes and adoption behaviors regarding MHSs. To fill this gap, this study integrates behavioral reasoning theory (BRT) and protective motivation theory (PMT) to develop a research model by uncovering the reasoning process of personal values, RF and RA, adoption attitudes and behavior toward MHSs. In particular, health consciousness (HC) is selected as the value. Comparative advantage, compatibility and perceived threat severity are considered the RF subconstructs; value barriers, risk barriers and tradition and norm barriers are deemed the RA subconstructs.

Design/methodology/approach

A total of 281 responses were collected to examine the model with the partial least squares structural equation modeling (PLS-SEM) method.

Findings

The results show that HC positively affects attitude through RA and RF. Additionally, RF partially mediates the relationship between HC and adoption behavior. This study contributes to a deeper understanding of user adoption behavior in MHS and provides practical guidance for the health services industry.

Originality/value

This study contributes to the existing MHS literature by understanding the joint influences of personal values, RF and RA on user attitude, which eventually determines users' adoption decisions regarding MHSs.

Abstract

Purpose

The paper aims to take stock of China’s recent biopharmaceutical industry development by analyzing product innovation and changes in the firms’ product portfolios during the five-year period between 2012 and 2017.

Design/methodology/approach

The paper introduces a classification of biopharmaceutical products. By applying the classification to the product data of China’s drug regulator, the CFDA, it becomes possible to trace the developments within the sector by looking at changes in the number of firms within each subgroup and changes in the number of subgroups in which each firm is involved. The classification allows an evaluation of the latest product innovation achievements.

Findings

The paper demonstrates a mild shakeout of firms in the relatively long-existing domestic market segments, a trend toward more specialized product portfolios and an enduring prevalence of innovation strategies aimed at exploiting relatively unpopulated domestic market niches instead of pioneering entirely new products. Especially the capability of upgrading to second-generation protein therapeutics has become a key criterion for separating the wheat and the chaff in China’s domestic sector. The paper moreover points out the relevance of acquisitions as a corporate growth strategy.

Research limitations/implications

The research does not consider complementary indicators, product pipelines in particular. Future research should compare patterns across emerging economies.

Originality/value

The paper is unique in using the CFDA database for systematic academic research on (bio)pharmaceutical innovation and in introducing a biopharmaceutical product classification to trace innovative activities and changes in corporate product portfolios over time.

Abstract

Purpose

Phenolic epoxy vinyl ester resin (PEVER) is an advanced resin matrix, which has excellent heat resistance, electrical insulation. However, the brittleness and poor toughness of its curing product limited its application, so this paper aims to modify the PEVER with hyperbranched polyimide (HBPI), so as to enhance the toughness, heat resistance and dielectric properties of PEVER.

Design/methodology/approach

Hexamethylene diisocyanate trimer was used as the central reactant. Methyl tetrahydrophthalic anhydride was used as the branching unit, stannous octoate was used as the catalyst and hydroquinone was prepared as the inhibitor. Then, the hyperbranched structure of HBPI was characterized by Fourier transform infrared spectrometer and 13C-NMR. Next, PEVER was mixed with different contents of HBPI, and then the authors tested its curing product.

Findings

It is found that with the addition of HBPI, the free volume of the system was increased and the content of polar groups was decreased in each unit space, so the dielectric constant (ε) and the dielectric loss (tanδ) were decreased. In addition, PEVER could be well toughened by HBPI and the thermal stability of PEVER was improved.

Originality/value

HBPI has excellent heat resistance. The addition of hyperbranched polymer increases the free volume of the system so it can slow down the transfer of stress and its nearly circular structure can absorb the impact energy from all directions. Moreover, an appropriate amount of free volume can decrease the dielectric constant of PEVER by reducing the content of polar groups.

Abstract

Purpose

Epoxy resin (EP) is a kind of thermosetting resin, and its application is usually limited by poor toughness. In this case, a type of new flexible chain blocking hyperbranched polyester (HBP) was designed and synthesized. The purpose of this study is to enhance the toughness and dielectric properties of EP.

Design/methodology/approach

P-toluene sulfonic acid was used as the catalyst, with dimethy propionic acid as the branch unit and pentaerythritol as the core in the experiment. Then, n-hexanoic acid and n-caprylic acid were, respectively, put to gain HBP with a n-hexanoic acid and n-caprylic acid capped structure. The microstructure, mechanical properties, insulation properties and dielectric properties of the composite were characterized for the purpose of finding the appropriate proportion of HBP.

Findings

HBP enhanced the toughness of epoxy-cured products by interpenetrating polymer network structure between the flexible chain of HBP and the EP molecular chain. Meanwhile, HBP reduced the ε and tgδ of the epoxy anhydride-cured product by reducing the number of polar groups per unit volume of the EP through free volumes.

Research limitations/implications

Yet EP is a kind of thermosetting resin, which is widely used in coating, aerospace, electronics, polymer composites and military fields, but it is usually limited by poor toughness. In a word, it is an urgent priority to develop new EP with better toughness and mechanical properties.

Originality/value

At present, HBP has been applied as a new kind of toughening strategy and as a modifier for EP. According to the toughening mechanism of HBP modified EP, the free volume of HBP creates a space for the EP molecule to move around when loaded. Moreover, the free volume could cause the dielectric constant of EP to diminish by reducing the content of polarizable groups. Meanwhile, the addition of HBP with flexible chains grafted to the EP could develop an interpenetrating network structure, thus further enhancing the toughness of EP

Abstract

Purpose

The paper aims to address how firms make strategic adjustment to the changing resource availability in different monetary policy conditions and how the stickiness of cost influences the strategic adjustment, and to dig out the major internal and industrial factors that influence the relationship between strategic change and monetary policy conditions.

Design/methodology/approach

The mechanism of how monetary policy affects strategic change is expounded by resource-based view and transaction cost theory. The balanced panel data of 422 companies of manufacturing industry listed in Chinese A share market before the end of 2003 from 2004-2013 are selected as sample to test the theoretic hypotheses.

Findings

It was found that looser monetary policy results in greater strategic change than the tighter one for the high adjustment cost. External capital dependence and industrial competition intensity strengthen the positive correlation between monetary policy condition and strategic change. Private firms are more susceptible to money supply condition change compared with state-owned enterprises. Companies tend to expand investment on fixed asset but to shrink investment on R & D and trademark in looser money supply condition.

Practical implications

Companies make bigger strategic adjustment in looser monetary policy condition for the greater availability of financial resources and lower market risk, but smaller adjustment in the tight one. However, owing to the sunk cost and the high adjustment cost, companies are not suggested to make aggressive strategic adjustment in the loose monetary conditions so as to avoid overcapacity and financial risk in tight monetary policy condition. For the policy-maker, as loose monetary policy cannot stimulate innovation but boost expansion on capacity, it is better to strengthen the resources configuration mechanism of monetary policy when making monetary policy.

Originality/value

This paper fulfils a theoretic gap to study the mechanism of how monetary policy influence corporate strategic resource reconfiguration via affecting the resource base of a company by combining resource-based view and transaction cost theory.

Abstract

Purpose

In this study, fabrication of polymer and cotton fabric exhibiting stimuli-responsive wetting and water vapor permeability features together with antibacterial activity was aimed.

Design/methodology/approach

Temperature and pH-responsive poly(N-isopropyl acrylamide-graft-chitosan) (PNIPAM-g-CS) copolymer were produced via the free radical addition polymerization method and fixed to the cotton fabric using butane tetracarboxylic acid (BTCA) cross-linker by double-bath impregnation method. The chemical structure of the graft copolymer was characterized by Fourier-transform infrared spectroscopy (FT-IR) spectroscopy and H-Nuclear magnetic resonance (1H NMR) analyses. Thermo-responsive behavior of the fabric was investigated by wetting time and water uptake tests, contact angle measurement and surface energy calculation. Additionally, antibacterial activity of the fabric treated with copolymer was studied against S. aureus bacterium.

Findings

PNIPAM-g-CS graft copolymer was synthesized successfully, which had lower critical solution temperature (LCST) value of 32 °C and exhibited thermo-responsive property. The treated fabrics exhibited hydrophilic character at temperatures below the LCST and hydrophobic character at temperatures above the LCST. It was found that polymer-coated fabric could have regulated the water vapor permeability by the change in its pore size and hydrophilicity depending on the temperature. Additionally, treated fabric displayed a pH-responsive water absorption behavior and strong antibacterial activity against S.aureus bacterium.

Originality/value

In the study, it has been shown that the cotton fabrics can be fabricated which have antibacterial activity and capable of pH and temperature responsive smart moisture/water management by application of copolymer. It is thought that the fabric structures developed in the study will be promising in the production of medical textile structures where antibacterial activity and thermophysiological comfort are important.
