Abstract

Purpose

Hospital at Home (HAH) is a concept slowly expanding over time. At first this type of organization was used to accomplish low‐technical tasks. The main objective was to increase bed availability in hospitals for new patients. Nowadays, HAH structures are able to undertake more technical complex care such as (but not limited to) end‐of‐life care, chemotherapy and rehabilitation. The purpose of this paper is to propose a new methodology to make an unbiased economic comparison between HAH structures and traditional hospitalization.

Design/methodology/approach

This article accomplishes two main objectives: in the first part the authors propose a comprehensive literature review dealing with the comparison between traditional hospital and home care structures from an economic standpoint, showing that results are highly dependent on initial conditions of the study (patient health state, territory settings, bio‐medical parameters); in the second part the authors propose an unbiased economic comparison approach between health care provided in traditional hospital and home care network using formal modelling with Petri nets and discrete event simulation. As an example for the comparison a multi‐session treatment is proposed. Various scenarios are tested to ensure that results will be maintained even if initial conditions change. Relevant performance indicators used for comparison are economic costs from the point of view of the insurance and economic costs related to the consumption of resources.

Findings

It is found that HAHS can be used to control and improve patients flow on hospitals. Decisions about offering a multi‐session treatments at home must be taken, not only because of economic impacts on hospitals, but also because it follows strategic goals of the organization. This decision must be issued following a strategic analysis. Some important questions are: How should newly available beds be used in the hospital? Which territories will be covered? What is the best logistic strategy for delivering the medicines?

Originality/value

Comparing HAH with traditional hospitalization can provide useful information to healthcare authorities when deciding to create, or not, new HAH structures.

Abstract

Purpose

This study aims to propose an improved affine interval truncation algorithm to restrain interval extension for interval function.

Design/methodology/approach

To reduce the occurrence times of related variables in interval function, the processing method of interval operation sequence is proposed.

Findings

The interval variable is evenly divided into several subintervals based on correlation analysis of interval variables. The interval function value is modified by the interval truncation method to restrain larger estimation of interval operation results.

Originality/value

Through several uncertain displacement response engineering examples, the effectiveness and applicability of the proposed algorithm are verified by comparing with interval method and optimization algorithm.

Abstract

Purpose

In response to the government’s decision to make “entrepreneurship and innovation for all” a national strategy in its 2015 annual work report, Chinese professionals in the library field have expressed a growing interest in makerspaces. This study aims to provide an overview of their current research studies and attempts in constructing makerspaces.

Design/methodology/approach

The authors aggregated research materials on library makerspaces in China from two sources: journal articles from the China National Knowledge Infrastructure Database and online news reports from the search engine Baidu.com. Content analysis was used to extract information regarding visions and perceived values, service models and technology adoption.

Findings

While a growing number of Chinese academic publications are concerned with library makerspaces, the existing research focuses on foreign cases and offers few empirical studies on domestic application scenarios. Libraries and researchers in China hold a positive and supportive attitude toward makerspaces. 3D printing is the most frequently mentioned technology, and free-to-use, promoting communication and realization of ideas and dreams are the most emphasized values. Libraries should highlight their own unique advantages and tap into their resources and services in mutually beneficial collaborations with other types of makerspaces.

Research limitations/implications

First, the results of this study cannot fully summarize the development status of makerspaces in Chinese libraries. Second, the research materials used in this study may be biased, especially the news reports.

Practical implications

This paper presents a semantic, visualized analysis of aggregated online news articles and journal articles on library makerspaces in China in an attempt to summarize their characteristics and guiding values, validate the advantages of library makerspaces and give suggestions on improving their service models.

Social implications

This paper introduces the development trend of makerspace in Chinese libraries, so that researchers at home and abroad can learn more about the development of Chinese library.

Originality/value

This study comprehensively overviews the development of library makerspaces in China. The results provide suggestions to improve maker services in library.

Abstract

Purpose

The purpose of this paper is to examine the effects of cross-border mergers and acquisitions (M&As) by firms in the emerging marketing on stock market cumulative abnormal returns (CARs). This research focuses on the acquiring firms in emerging markets and broadens the existing scope which highlights the M&As by firms in developed countries.

Design/methodology/approach

Regarding the controversial argument on the effect of cross-border M&As, the authors introduce a resource-based theory to explain the motivation of M&As by Chinese firms, conduct an event study analysis of 472 international acquisitions by Chinese firms from 2010 to 2015 and indicate cross-border M&As as a positive signal in the stock market.

Findings

The results reveal that cross-border M&As result in significantly positive CARs in a short term for the acquiring firms listed in mainland markets but not for that in the Hong Kong market. Furthermore, consistent with signaling theory and the investors’ heuristic thinking in decision-making, investors may adopt the technological innovation capability of the country where the target firms locate, and the acquiring firm’s preannouncement in shaping their positive judgment of the acquiring firm’s near future performance.

Originality/value

The authors distinguished the responses of the investors from the mainland and Hong Kong stock markets and investigated how the knowledge of the national innovation capability of the target firm and acquisition preannouncement influence the investors’ interpretation of the cross-border M&As as a market signal.

Abstract

Purpose

China has proposed two-stage goals of carbon peaking by 2030 and carbon neutralization by 2060. The carbon emission reduction effect of the power industry, especially the thermal power industry, will directly affect the progress of the goal. This paper aims to reveal the spatial-temporal characteristics and influencing factors of carbon emission efficiency of the thermal power industry and proposes policy suggestions for realizing China’s carbon peak and carbon neutralization goals.

Design/methodology/approach

This paper evaluates and compares the carbon emission efficiency of the thermal power industry in 29 provinces and regions in China from 2014 to 2019 based on the three-stage slacks-based measure (SBM) of efficiency in data envelopment analysis (DEA) model of undesired output, excluding the influence of environmental factors and random errors.

Findings

Empirical results show that during the sample period, the carbon emission efficiency of China’s thermal power industry shows a fluctuating upward trend, and the carbon emission efficiency varies greatly among the provincial regions. The carbon emission efficiency of the interregional thermal power industry presents a pattern of “eastern > central > western,” which is consistent with the level of regional economic development. Environmental factors such as economic level and environmental regulation level are conducive to the improvement of carbon emission efficiency of the thermal power industry, but the proportion of thermal power generation and industrial structure is the opposite.

Originality/value

This paper adopts the three-stage SBM–DEA model of undesired output and takes CO2 as the undesired output to reveal the spatial-temporal characteristics and influencing factors of carbon emission efficiency in China’s thermal power industry. The results provide a more comprehensive perspective for regional comparative evaluation and influencing factors of carbon emission efficiency in China’s thermal power industry.

Abstract

Purpose

This study aims to reduce the weight of the door, improve the operating efficiency and ensure the safety of vehicle operation.

Design/methodology/approach

Based on traditional aluminium alloy doors, a new type of honeycomb composite material was developed. Tests were conducted to determine the honeycomb compression resistance, honeycomb and skin shear performance, plate bending, thermal conductivity and environmental protection. Eight doors were developed based on the full-side open structure, and static strength and stiffness analyses were performed simultaneously. To solve door vibration problems, modal analysis and test were carried out.

Findings

The test results showed that the weight of the door was reduced by more than 40% whilst ensuring the strength and stiffness of the vehicle. The first–sixth-order test mode of the door was increased by more than 14% compared with existing aluminium alloy doors.

Originality/value

A new type of honeycomb composite material was used in this study. The test results showed that the weight of the door was reduced by more than 40% whilst ensuring the strength and stiffness of the vehicle. The 1st-to-6th order test mode of the door was increased by more than 14% compared with the existing aluminium alloy door.

This paper aims to develop an efficient numerical method for nonlinear transient heat conduction problems with local radiation boundary conditions and nonlinear heat sources.

Abstract

Purpose

This paper aims to develop an efficient numerical method for nonlinear transient heat conduction problems with local radiation boundary conditions and nonlinear heat sources.

Design/methodology/approach

Based on the physical characteristic of the transient heat conduction and the distribution characteristic of the Green’s function, a quasi-superposition principle is presented for the transient heat conduction problems with local nonlinearities. Then, an efficient method is developed, which indicates that the solution of the original nonlinear problem can be derived by solving some nonlinear problems with small structures and a linear problem with the original structure. These problems are independent of each other and can be solved simultaneously by the parallel computing technique.

Findings

Within a small time step, the nonlinear thermal loads can only induce significant temperature responses of the regions near the positions of the nonlinear thermal loads, whereas the temperature responses of the remaining regions are very close to zero. According to the above physical characteristic, the original nonlinear problem can be transformed into some nonlinear problems with small structures and a linear problem with the original structure.

Originality/value

An efficient and accurate numerical method is presented for transient heat conduction problems with local nonlinearities, and some numerical examples demonstrate the high efficiency and accuracy of the proposed method.
