Listening to the patient voice: using a sentic computing model to evaluate physicians’ healthcare service quality for strategic planning in hospitals

Online physician reviews (OPRs), also known as electronic word of mouth, have become the primary source of information for patients while making health consultation decisions. However, different techniques to analyze these reviews by machines have not been frequently applied yet in this domain. In this study, a novel method for opinion mining is being proposed to fill the existing research gap, that is, a hybrid approach to sentic computing. This approach integrates artificial intelligence and semantic web techniques to implicitly analyze OPRs in order to evaluate patient perceptions of healthcare service quality. We develop our methodology by using the following three main tasks: (1) sentence-level topic spotting (a topic-analysis procedure) to extract major topics, (2) a sentic computing framework to perform concept-level sentiment analysis (polarity detection on the categorized sentences), and (3) root cause and strengths, weaknesses, opportunities, and threats (SWOT) analyses to identify SWOT for healthcare organizations. Analyses results of 47,499 OPRs from the UK-based website (Iwantgreatcare.org) show that the proposed hybrid approach has accurately classified concept words to their corresponding topics, and it has also outperformed the similar other methods of topic extraction in the healthcare domain. The results also indicate that the proposed approach can better contribute to the overall performance analyses for healthcare organizations, which could help practitioners in improving service-quality measures based on the real voices of patients. The proposed model also provides a theoretical basis for formulating quality measures for the healthcare sector.

     

Does ownership matter for service delivery value? an examination of citizens’ service satisfaction

Governments across the world outsource service delivery to external agents, but does ownership matter for service delivery value? Though theory points to clear ownership differences on effectiveness, there remains limited empirical evidence of the impact of ownership on citizens’ satisfaction. Focusing on local authorities in England, we draw on secondary data (2007 and 2009) to examine if ownership type matters. The findings indicate that ownership – public, non-profit, private – confers no direct benefits for citizens’ satisfaction suggesting that the outsourcing decision should not rely on unfounded assumptions about performance differentials between ownership types. The implications for public management are explored.     

How do managerial techniques evolve over time? The distortion of “facilitation” in healthcare service improvement

When applied to solving real-world problems in the public sector, managerial techniques are likely to evolve over time in response to the context of their implementation. The temporal dynamics of this evolution and its underlying processes, however, remain under-researched. To address this gap, we present a qualitative longitudinal case study of a UK-based knowledge mobilization programme utilizing “facilitation” as a service improvement approach. We describe the processes underpinning the distortion of facilitation over time and argue that an uncritical and uncontrolled adaptation of managerial techniques may mask the unsustainable nature of the resulting improvement outcomes captured by conventional performance measurement.     

HR managers in five countries: what do they do and why does it matter?

The 1980s saw the need for change in the organizational role of human resource (HR) professionals, from the traditional employee champion and administrative expert to strategic business partner and change agent. The argument posited was that a more challenging environment compels organizations to turn to managing their HRs as a source of competitive advantage and that means an increasing business partnership for HR professionals. However, very few studies examine the execution of these multiple, sometimes contradictory roles, despite the risk that neglecting traditional roles endanger organizational performance in the long term. This five-country comparative study finds that multiple roles are at least moderately executed, and that these HR roles have different impact depending on the aspect of organizational performance. As well, a more challenging environment, defined here as legal constraints and industry challenges, generally does not have a significant moderating effect on the impact of the different HR roles on organizational performance.     

Building dynamic capabilities in product development: How do contextual antecedents matter?

This paper contributes to elucidate the nature, antecedents and outcomes of dynamic capabilities in product development. Building on the organizational context literature, the paper uses an input–process–output framework to argue that a context characterized by a combination of autonomy, performance management, support and trust facilitates dynamic capabilities for continuous product development. Further, dynamic capabilities shape product development competences. Empirical evidence is provided by performing survey research with data collected from 80 product development efforts developed in Spain. The paper includes conclusions, limitations and future research potentials for those with an interest in supporting dynamic capabilities.     

Social capital and cultural adjustment of international assignees in NGOs: do support networks really matter?

International assignees face cultural adjustment challenges in their host countries in work and nonwork situations. At the same time, social capital theory suggests that individuals can access and mobilize resources from their social networks. We explore the use of social networks by international assignees from a non-governmental organization in their cross-cultural adjustment to the host country. Specifically, we are interested in the individuals who directly provided support to the expatriate, a network that we term the ‘current assignment support network’. We focus on the size, type and frequency of contact of the international assignee's support network, and investigate to what extent these variables can predict overall cultural adjustment to the host country, or separate dimensions of cultural adjustment such as interaction adjustment, general adjustment and work adjustment. Our findings indicate that certain characteristics of the international assignee's current assignment support network do impact their cultural adjustment to the host country, but that the effects are moderated by whether the assignee has prior international experience.

Are there major differences in the attitudes and service quality of standard and seasonal employees? An empirical examination and implications for practice

Despite the increased use of seasonal employees by organizations, few studies have been completed on the attitudes and service quality of seasonal office workers. Using Lautsch's classification model, we analyzed the organizational context in which the standard and seasonal workers in this study were employed. Hypotheses were developed based upon the organizational analysis and social exchange theory. Results from archival data obtained from a web‐based organizational survey of 205 clerical and professional workers indicated contrary to expectations, standard and seasonal employees did not significantly differ in terms of perceptions of overall job conditions, perceived organizational support (POS), or job engagement. However, seasonal employees did report significantly fewer opportunities to work on challenging tasks, less comfortable physical working conditions, and less job security than the standard workers. As predicted, standard employees reported significantly higher levels of service quality performance than seasonal employees. Additionally, job engagement mediated the relationship between POS and service quality for both the standard and seasonal employees. Implications for managing seasonal employees are discussed.     

The patterns of cross-border portfolio investments in the GCC region: do institutional quality and the number of expatriates play a role?

In this paper, we document the determinants of portfolio investments to Gulf Cooperation Council (GCC) economies by bringing up the role played by market forces, cultural affinities, and institutional quality. We classify the GCC economies as host to 35 countries as per the Coordinated Portfolio Investment Surveys (CPIS) of the IMF for the period 2001–2006. Using the CPIS data and data from various other reliable sources and appropriate panel data analysis techniques, we find a number of interesting results: 1) the relatively higher quality of institutional set up in GCC in comparison to other countries; 2) the relative volume of expatriates across source countries in GCC soil; and 3) bilateral factors such as trade linkages between GCC and source countries, all statistically and significantly explain portfolio investments to the GCC region. Additionally, we uncover the existence of a portfolio “GCC bias”. That is, GCC investors exhibit a strong preference towards their own markets when allocating their cross border financial asset holdings.     

Determinants of bank interest margins in Russia: Does bank ownership matter?

This paper analyzes interest margin determinants in the Russian banking sector with a particular emphasis on the bank ownership structure. Using unique bank-level data covering Russia's entire banking sector for the 1999–2007 period, we find that the impact of a number of commonly used determinants such as market structure, credit risk, liquidity risk and size of operations differs across state-controlled, domestic-private and foreign-owned banks. At the same time, the influence of operational costs and risk aversion is homogeneous across ownership groups. The results overall suggest that the form of bank ownership needs to be considered when analyzing interest margin determinants.     

How do firm characteristics affect behavioural additionalities of public R&D subsidies? Evidence for the Austrian transport sector

Interest of STI policies to influence the innovation behaviour of firms has been increased considerably. This gives rise to the notion of behavioural additionality, broadening traditional evaluation concepts of input and output additionality. Though there is empirical work measuring behavioural additionalities, we know little about what role distinct firm characteristics play for their occurrence. The objective is to estimate how distinct firm characteristics influence the realisation of behavioural additionalities. We use survey data on 155 firms, considering the behavioural additionalities stimulated by the Austrian R&D funding scheme in the field of intelligent transport systems in 2006. We focus on three different forms of behavioural additionality—project additionality, scale additionality and cooperation additionality—and employ binary regression models to address this question. Results indicate that R&D related firm characteristics significantly affect the realisation of behavioural additionality. R&D intensive firms are less likely to substantiate behavioural additionalities, while small, young and technologically specialised firms more likely realise behavioural additionalities. From a policy perspective, it may be concluded that direct R&D promotion of firms with a high R&D intensity may be misallocated. Attention of public support should be shifted to smaller, technologically specialised firms with lower R&D experience. The findings deliver important insights into interactions of public R&D support and R&D behaviour of firms operating in the Austrian transport sector, bearing significant implications for future policy designs.     

New results on the effect of maternal work hours on children's overweight status: Does the quality of child care matter?

Existing empirical research on child overweight derives mainly from North America and points at rising maternal employment as an explanation for the increasing trend in child weight. These results cannot be replicated in Denmark, where an increase in maternal work hours does not increase the likelihood of weight problems for their children. This paper tests four possible explanations for this difference: (1) the effect of maternal employment on child obesity is heterogeneous and varies according to the country's weight distribution; (2) the quality of child care is on average higher in Denmark; (3) the counterfactual care provided by Danish mothers is of lower quality; and (4) Danish fathers contribute significantly to their children's health. This paper finds evidence consistent with the hypotheses that Danish child care and fathers play a significant role in explaining the absence of a significant relationship between maternal work hours and children's overweight status.     

Impact of high-speed railway on urban resilience in China: Does urban innovation matter?

Based on calculating the urban resilience index from five aspects of economy, society, institutions, infrastructure, and ecology by adopting the entropy method, this study applies the time-varying DID model to systematically examine HSR's impact on China's urban resilience, on basis of which its heterogeneities and the mediating effect of urban innovation are also quantified. The findings reveal that: (1) HSR can significantly promote China's urban resilience, as supported by various robustness tests. (2) HSR can significantly improve economic and institution resilience of cities, but does not play a significant role on social resilience and infrastructure resilience, and has a negative effect on ecological resilience. (3) The driving effects of HSR on the resilience of core cities, large cities, and non-resource-based cities are more significant. (4) Urban innovation is an important channel through which HSR impacts urban resilience. The conclusions of this study can offer useful insights for China's future HSR planning and resilient cities construction.     

Does entrepreneurial activity matter for economic growth in developing countries? The role of the institutional environment

The discussion on which institutions determine entrepreneurial activity – and the role of institutions in the aggregated output for developing countries – is as yet unresolved. The extant literature about entrepreneurship recognizes new ventures as potential mechanisms for long-term development. Yet, there is a consensus on the lack of evidence, particularly for these countries. Drawing on institutional economics, this article explores the interrelationships among institutional environment, entrepreneurial activity, and economic growth. To this end, we use simultaneous-equation panel data models for a sample of 14 developing countries (78 observations) over the period of 2004–2012. The main findings suggest a causal chain running from institutions to opportunity entrepreneurship, which is linked to the economic growth of emerging economies. In particular, we find that institutional factors – such as the number of procedures to start a new business, private credit coverage ,, and access to communication– influence entrepreneurial activity driven by opportunity. Policy implications for developing countries could be derived in order to enhance their economic performance through entrepreneurial activity.

     

Self-employment and business cycle persistence: Does the composition of employment matter for economic recoveries?

Self-employment comprises an important share of employment in many countries, and tends to expand during downturns through higher inflows from unemployment. Furthermore, countries with higher self-employment shares exhibit lower cyclical output persistence. I build a business cycle model with frictional labor markets where individuals can be self-employed or salaried employed. I show that economies with larger self-employment shares exhibit faster economic recoveries. Differences in the ease of entry into self-employment as the economy recovers explain the contrasting cyclical dynamics. The model successfully captures the cyclical patterns of self-employment and the relationship between self-employment and output persistence in the data.     

Technological changes in the era of digitalization: What do collective agreements tell us?

Unionized organizations are implementing more than ever technological changes to cope with an increasingly changing and highly digital environment. Despite the extensive literature on union responses to changes, there is not much evidence on how unions and employers draft provisions pertaining to technological changes in collective agreements. Therefore, this paper aims to conduct an in-depth analysis of these provisions in over 500 collective agreements signed between 2000 and 2020. Specifically, this study focuses on office workers in two of the most important Canadian industries, namely, the healthcare and manufacturing sectors. The findings indicate that within the examined provisions, the regulation of technological change varies along a continuum that extends from no obligations to stringent obligations on the part of the employer. Moreover, the results show that these provisions have remained stable over the past two decades.     

Two decades of cognitive bias research in entrepreneurship: What do we know and where do we go from here?

The study of entrepreneurial cognitive bias emerged about two decades ago and has received growing attention in entrepreneurial research. However, this is the first comprehensive review of the studies published in this field and therefore describes the current state of the art of cognitive bias research in entrepreneurship. This paper identified a total of 54 relevant articles and structures them by a typology of bias. It shows that a considerable number of articles cover overoptimism and overconfidence, while limited attention has been given to other biases such as illusion of control, the belief in the law of small numbers, escalation of commitment, planning fallacy, status quo bias, self-serving bias, and hindsight bias. Results of this review show that studies examining overoptimism and overconfidence have delivered most consistent results. The focus of the review lies on logically structuring the body of research by assessing the key issues in the determinants and in the consequences of each bias and thereby identifying a range of new research opportunities. Special emphasis was placed on incorporating insights from conceptual papers.     

Trading and non-trading period realized market volatility: Does it matter for forecasting the volatility of US stocks?

We study the potential merits of using trading and non-trading period market volatilities to model and forecast the stock volatility over the next one to 22 days. We demonstrate the role of overnight volatility information by estimating heterogeneous autoregressive (HAR) model specifications with and without a trading period market risk factor using ten years of high-frequency data for the 431 constituents of the S&P 500 index. The stocks’ own overnight squared returns perform poorly across stocks and forecast horizons, as well as in the asset allocation exercise. In contrast, we find overwhelming evidence that the market-level volatility, proxied by S&P Mini futures, matters significantly for improving the model fit and volatility forecasting accuracy. The greatest model fit and forecast improvements are found for short-term forecast horizons of up to five trading days, and for the non-trading period market-level volatility. The documented increase in forecast accuracy is found to be associated with the stocks’ sensitivity to the market risk factor. Finally, we show that both the trading and non-trading period market realized volatilities are relevant in an asset allocation context, as they increase the average returns, Sharpe ratios and certainty equivalent returns of a mean–variance investor.     

Measuring the concentration of information and communication technology infrastructure in Australia: Do affordability and remoteness matter?

This study measures the concentration of information and communication technology (ICT) infrastructure and expenditure inequality in the disaggregated spatial unit of various locations in Australia. Using survey data from the Household, Income and Labour Dynamics in Australia, a composite concentration index for ICT infrastructure is constructed for urban and rural households. In addition, the Gini coefficient of ICT expenditure is computed to measure the concentration of affordability of ICT services. Findings demonstrate that the concentrations of ICT infrastructure and affosrdability are profound in the Greater Sydney and Greater Melbourne areas. Nevertheless, results indicate that the remoteness of spatial units has a noteworthy impact on the concentration of ICT infrastructure. In addition, canonical correlation analysis reveals that the association between the concentration of ICT infrastructure and inequality in the affordability of ICT services is statistically significant. These findings imply that policy makers should employ a holistic approach that will not only include technological and economic considerations but also examine place-based context in designing an all-inclusive ICT policy.     

Foreign capital inflows and poverty linkages in South Asia: Do the forms of capital inflows matter?

The relationship between foreign direct investment and poverty reduction has received modest attention in the empirical literature. However, little is known about the relative significant impact of different forms of capital inflows on poverty reduction. This study attempts to investigate the impact of different forms of capital inflows (foreign direct inflows, portfolio equity and portfolio debt inflows) on poverty reduction in major South Asian economies during the post-reform period. The capital inflows-poverty nexus is explored using panel econometric methods robust to cross-sectional dependence. Our empirical results show that while portfolio equity inflows exert a favorable impact on poverty reduction, foreign direct inflows and debt inflows fail to influence poverty. The panel causality results demonstrate that portfolio equity inflows also support poverty alleviation via stimulating economic growth and trade openness. The findings of our study highlight the importance of considering the differential welfare impacts of different forms of capital inflows while implementing capital account liberalization.
