Purpose The purpose of this paper is to estimate the mean life expectancy (LE) and the expected years of life lost (EYLL) for ischemic stroke and intracerebral hemorrhage. Design/methodology/approach This retrospective cohort study included 5,210 patients with a diagnosis of first ischemic stroke or intracerebral hemorrhage between 2005 and 2013 from Ramathibodi Hospital, Bangkok, Thailand. The survival of each case was followed until December 31, 2016. A semiparametric extrapolation method was applied to estimate the lifetime survival function relative to an age and sex-matched reference population. Findings Of 5,210 patients, 74.2 percent experienced ischemic stroke. About 54.3 percent were men. Mean age at diagnosis was 64.3 years. The mean LE was 12.5 years for ischemic stroke and 12.0 years for intracerebral hemorrhage. The EYLL among patients with intracerebral hemorrhage was significantly higher than among those with ischemic stroke (10.1 vs 5.7). Women were expected to lose more LE than men for both types of stroke (p-value<0.05), while younger aged patients were expected to lose more years of life than older ones. Originality/value This study fulfilled an identified need to estimate LE and EYLL among patients with ischemic stroke and intracerebral hemorrhage.

Purpose – Family businesses represent the largest share of small-sized firms in majority of economies around the world. Having in mind the global economic situation this trend is expected to be continued. With the goal of better understanding of the process of transferring the business to the next generation, which ensures a long-term success, the purpose of this paper is to investigate expectations of student’s with family business background. Design/methodology/approach – The research addresses the issue of an individual’s perception of entrepreneurship and the related factors that influence individual’s decision on whether to build a career as an employee, become a successor of family business or start own business as an independent entrepreneur. The authors separately analyzed West European (data from another study), East European and Slovenian senior student population for the purpose of comparative study. Students were surveyed and binominal regression was used for statistics. Findings – The results show differences between investigated populations and positions Slovenian students in the mean. The authors anticipate that differences are caused by historical, cultural and educational backgrounds. This challenging area is raising a lot of sub-questions for possible future research. Originality/value – The value of the study is in the replication of the existing methodology from the benchmarking study and result comparison.

People Search

PurposePrevious research has repeatedly shown that people only search for files in a small minority of cases when they do not remember the file's location. The current study aimed to examine whether there is a group of hyper-searchers who search significantly more than others. Based on previous neurocognitive studies, this study aims to hypothesize that if such a group exists, they will have superior verbal memory and reduced visuospatial memory.Design/methodology/approachIn total, 65 participants completed a questionnaire estimating their search percentages, as well as reporting demographic data. Verbal memory was measured using the Wechsler logical memory test, and visuospatial memory was assessed using an online card memory game.FindingsHyper-searchers were defined as participants with search percentage of over one standard deviation (SD) above the mean. The average search percentage of the seven participants who met this criterion was 51% (SD = 14%), over five times more than the other participants (M = 10%, SD = 9%). Similar results were obtained by re-analyzing data from four previous papers (N = 1,252). The results further confirmed the hypothesis that hyper-searchers have significantly better verbal memory than other participants, possibly making searching easier and more successful for them. Lastly, the search percentage was positively predicted by verbal memory scores and negatively predicted by visuospatial memory scores. Explanations and future research are discussed.Originality/valueThis preliminary study is the first to introduce the concept of hyper-searchers, demonstrate its existence and study its causes.

Purpose The purpose of this paper is to review and evaluate the methods commonly used in accounting literature to correct for cointegrated data and data that are neither stationary nor cointegrated. Design/methodology/approach The authors conducted Monte Carlo simulations according to Baltagi et al. (2011), Petersen (2009) and Gow et al. (2010), to analyze how regression results are affected by the possible nonstationarity of the variables of interest. Findings The results of this study suggest that biases in regression estimates can be reduced and valid inferences can be obtained by using robust standard errors clustered by firm, clustered by firm and time or Fama–MacBeth t-statistics based on the mean and standard errors of the cross section of coefficients from time-series regressions. Originality/value The findings of this study are suited to guide future researchers regarding which estimation methods are the most reliable given the possible nonstationarity of the variables of interest.

Purpose The purpose of this paper is to investigate the effects of negotiation process and outcome on an individual’s desire to negotiate again with the same counterpart. Design/methodology/approach Data were collected from 115 dyads representing two companies negotiating an eight-issue property leasing agreement via e-mail. Desire to negotiate again was regressed on demographic/personality, process, and outcome measures. Findings Reaching an agreement was found to be significantly related to desire to negotiate again, while the number of messages exchanged and the mean number of competitive tactics employed were positively and negatively associated with reaching an agreement, respectively. Further, perceived honesty of self and counterpart were also associated with an individual’s desire to negotiate again. Originality/value This study focuses on an aspect of real negotiations often overlooked by researchers – the likelihood of future encounters with the same party – and examines three categories of factors that could affect a party’s desire to negotiate with a counterpart again – demographic/personality, process, and outcome (actual and perceived).

Purpose – The purpose of this paper is to deal with the qualitative analysis of hydrodynamic lubrication of asymmetric rollers with non-Newtonian incompressible power law lubricants including Newtonian. Design/methodology/approach – The fluid flow governing equations such as equation of motion along with continuity and thermal equations are solved first analytically and investigated numerically by the Runge-Kutta Fehlberg method. Findings – As a result of this work, it is found that there is a significant change in temperature, pressure, load and traction with Newtonian and non-Newtonian fluids. Research limitations/implications – The authors considered incompressible hydrodynamic lubrication of two rigid asymmetric rollers, one of them is assumed to be adiabatic. The convection term of the heat flow equation is taken in its average form. Originality/value – It is a theoretical problem of two heavily loaded rigid cylindrical rollers with cavitations, where the consistency of the power law lubricant is assumed to vary with pressure and the mean film temperature. It has not appeared in the literature.

Purpose – In recent years, there has been a big increase in the use of ethical attributes as marketing appeals. The purpose of this paper is to examine consumers’ willingness to pay for three selected ethical attributes, namely “Organic”, “Recyclable Packaging” and “Fairtrade” in monetary terms. Design/methodology/approach – A modified choice-based experimental design with manipulation of the key constructs was used to estimate the mean value of how much consumers are willing to pay for the selected attributes attached to a box of premium chocolates. The results are based on the responses of a total of 208 consumers. Findings – Of the three attributes, “Recyclable Packaging” has the strongest influence on the purchase decision, although this attribute generates the least additional value. The aggregated result shows that although consumers are willing to pay more for the product with ethical attributes than the one that is without, still around a half of them are not willing to pay more. In terms of demographics, the results show no significant differences between the two genders or different age groups in their willingness to pay for ethical attributes. As might be expected, willingness to pay was correlated with the level of consciousness of the ethical attributes. Originality/value – The findings of this study help management to think practically about the value consumers willing to pay for the selected attributes. The results show a significant synergy in a combination of ethical attributes in products.

Poultry Farmers

PurposeThe purpose of this paper is to examine the poultry farmer's willingness to pay for agricultural tax in the Dormaa Municipality of Ghana. Besides, the study analysed the mean agricultural tax and constraints impeding the payment of the agricultural tax.Design/methodology/approachOne hundred (100) poultry farmers were selected for the study. The logit and Kendall’s coefficient of concordance were used to examine the factors that influence payment of agricultural tax and the constraints impeding the payment of the agricultural tax, respectively.FindingsInstructively, 83% of the respondents were interested in the regressive taxation model relative to 12 and 5% who were interested in the proportional and progressive taxation model, respectively. The empirical results of the logit model revealed that tax awareness, probability of being audited and public service provision of roads influenced the poultry farmer's decision to pay for the agricultural tax. Perception of corruption and high tax rates were the primary constraints impeding the payment of the agricultural tax. The results further revealed that the farmers are willing to pay an average maximum amount of Ghc 152.00 (US 26 dollars) agricultural tax per month.Originality/valueDespite the increasing relevance of agricultural tax, studies on poultry farmer's willingness to pay agricultural tax have been scarce in West Africa, particularly, Ghana. As a consequence, this paper broadens the frontiers of the existing literature on agricultural tax as well as the constraints impeding the poultry farmers to pay agricultural tax.

Purpose This study aims to determine the threshold of salt taste recognition and to evaluate differences by sex, age and body mass index (BMI) among a sample of Moroccan population. Design/methodology/approach A simple-blind experimental study was conducted among 201 healthy subjects to determine the threshold of salt taste recognition and to evaluate differences by sex, age and BMI among a sample of Moroccan population. The threshold of salt taste recognition was determined based on the validated the three alternatives forced choice method. A total of 11 prepared solutions of sodium chloride at different concentrations ranging from 0–500 mmol/L were used. Findings The average of the total population was 14.6 ± 10.9 mmol/L. And, 84% of the total population recognized the salt taste at the concentration of 15 mmol/L. Women participants detected the salt taste at a lower rate (53% versus 38% at 8 mmol/L, p = 0.02, in women and men, respectively). The mean values of the threshold among women was significantly lower (12.6 ± 8.1 mmol/L) compared to men (16.7 ± 12.8 mmol/L), p < 0.001. No statistical difference was obtained among either age groups or BMI categories. Originality/value The present study showed that the average threshold of salt taste recognition is high, and that it is even higher in men compared to women. At a community level, a progressive reduction of salt in food items is recommended.

Background: The etiology of remote DWI lesions in acute intracerebral hemorrhage (ICH) is still unknown. Postulated mechanisms include intracranial or extracranial emboli, small vessel abnormalities and ischemia following acute intracranial hypertension. Our aim is to evaluate the presence of spontaneous microembolic signals (MES) using transcranial Doppler (TCD) in acute ICH patients. Methods: Twenty patients with acute ICH were prospectively enrolled and monitored with TCD for 1 hour on admission days 1, 3 and 7. TCD monitoring was performed using 2MHz probes. Results: Of the 20 patients evaluated, 40% were females and mean age was 55.6±14.1. Eight patients (40%) had dyslipidemia, 15 (75%) hypertension, 5 (20%) diabetes, 2 (10%) ethanol abuse, 6 (30%) smoking and 1 (10%) had prior ischemic stroke. Most frequent location was lobar (9 patients). The mean hematoma volume was 13,5±17,9 ml. Of six patients who underwent MRI, 2 (20%) had remote DWI lesions. Embolic sources were found in 3 patients (1 with atrial fibrillation and 2 with large artery atherosclerosis). Microembolic signals were detected in seven patients (35%). Conclusion: The high occurrence of microemboli in patients admitted with acute ICH indicates a possible embolic mechanism for DWI lesions in these patients.

Depositary Receipts

Purpose – Single-listed American depositary receipts (ADRs) are traded in US markets, while their underlying share is not listed in the firm’s home market. The purpose of this paper is to empirically examine the factors affecting the returns and volatility of a sample of Chinese single-listed ADRs, in comparison with traditional Chinese ADRs. Design/methodology/approach – The methods used in this paper are similar to those used in the examination of traditional or dual-listed Chinese ADRs. However, motivated by the very nature of single-listed ADRs, the authors estimate a base model which includes factors from the two presumably most important markets for single-listed Chinese ADRs (i.e. the Chinese and US markets). In all of the estimations, the authors follow a two-step procedure. First, the authors estimate a GARCH(1,1) model with the mean equation modeled as an AR(p) process and from those models estimate GARCH (conditional) variances. Findings – In line with the evidence on traditional Chinese ADRs, the authors find that both the Chinese and the US markets are important predictors of single-listed ADR returns. The results are robust to variations in the model specifications. Originality/value – Single-listed ADR return behavior is still an under-researched topic. In this paper, the authors contribute to the literature on Chinese single-listed ADRs by empirically examining the determinants of their mean return and volatility.
