Thirty-six softwater lakes in central Ontario were sampled during 1988 to determine the relationship between metaphytic Zygnematacean algae and lake pH and the degree of complementarity between the presence of metaphyton and that of crayfish and tadpoles. A stratified sequential sampling program was developed to quantitatively measure and to objectively categorize average metaphyton abundance for each lake. A significantly greater proportion of lakes below pH 6 were found to contain extensive accumulations of metaphyton compared with lakes above pH 6. Lake pH and alkalinity were significantly correlated with metaphyton abundance. Macro-grazer density did not significantly influence the presence or absence of metaphyton, but reduced metaphyton abundance in those lakes which, because of their low pH or shallow depth, were predisposed to its accumulation. Managerial implications regarding the stocking of crayfish or tadpoles to limit the nuisance proliferation of metaphyton, and the importance of predaceous fishes in structuring this interaction, are discussed.

AbstractA sequential sampling program was designed for Coccinella septempunctata L. adults in wheat fields, based on a rapid visual counting method. This program takes into account the spatial heterogeneity of coccinellids and the efficiency of the counting method. The relationship between the mean and variance of the numbers sampled was described by Taylor’s power law.

An increasing demand for Islamic tourism has driven the concept of a ‘Halal’ (or permissible) friendly hotel into another level of business insight within the consumers’ travel market. The concept via its unique value proposition has rapidly become very attractive not only to Muslim tourists, but also to non-Muslim tourists globally. This study aims to examine the relationship linking ‘Halal’ friendly hotel attributes and customer satisfaction. Using purposive sampling, a total of 410 survey questionnaires were distributed to targeted respondents with only 323 usable feedbacks and used for data analysis. Regression results revealed that four main “Halal-friendly hotel” attributes have significant relationships with customer satisfaction. These include prayer facilities, Halal food, Islamic dress code and general Islamic morality. Of these four attributes, prayer facilities proved to have the most significant impact on customer satisfaction. Findings and managerial implications were further discussed in this article.

The paper has a two fold purpose - examine the impact of bar service operation practices (BSOP) on organizational performance (OP) and study the relationship between organizational performance and demographic variables. Based on a survey of 362 bar managers perceptions on the impact of bar service operation practices on organizational performance were assessed by 59 practices and 6 demographic variables. Bivariate test and ANOVA were employed to test the working hypothesis in the study. Results indicated that there is a positive relationship between the bar service operation practices and organizational performance. Further, the results indicate some practical and managerial implications to improve organizational overall performance.

We investigated the mediating effects of positive affect and strengths use in the relationship between perceived organizational support for strengths use (POSSU) and employees' task performance. Data were gathered at 2 time points, separated by a 2-week interval, from 157 employees working in various Chinese enterprises. We applied structural equation modeling and PROCESS macro analysis to the data. The results indicate that POSSU was positively related to task performance and that this relationship was mediated by strengths use. In addition, positive affect and strengths use played a sequential mediating role in the relationship between POSSU and task performance. However, positive affect was not a significant mediator in the POSSU–task performance relationship. Theoretical and managerial implications are discussed in the context of the literature on POSSU and task performance.

We applied role theory to test a theoretical model that explained how and why an implicit prototype match influences employees' proactive behavior in interpersonal contexts. After analyzing the reliability and validity of the variables, we used correlation and regression analyses to test our hypotheses with 342 participants from enterprises in China. The results show that (a) a stronger implicit prototype match increased employees' proactive behavior, (b) leader–member exchange mediated the relationship between implicit prototype match and proactive behavior, and (c) leader–member liking (employee's liking for leader and vice versa) moderated the relationship between implicit prototype match and leader–member exchange. Our findings provide theoretical support for implicit prototype theory from the implicit match perspective and have managerial implications for organizations seeking to improve employees' proactive behavior.

Orientation: Literature shows that job description and career prospect are connected to job satisfaction and it is seen that, in Mauritius, job description and career prospect impact job satisfaction.Research purpose: The purpose of the study was to determine the relationship between job description, career prospect and job satisfaction in Mauritius.Motivation for the study: It has been noticed that employees are dissatisfied when they perform duties outside their job description and also when they see that they do not have a good career prospect. Despite the existence of several researches, limited research exists in the Mauritian context. The outcome will provide significant relevance to existing knowledge.Research approach/design and method: A quantitative approach was adopted and a survey was conducted in a multinational company in Mauritius. A sample of 132 employees was chosen.Main findings: This research unravelled significant negative relationships between job description, career prospect and job satisfaction. The results revealed that, when duties are not well described or when duties are not in line with current responsibilities, the employees are dissatisfied. Similarly, the greater the chances that employees are not given the opportunity to get promoted, the more they are dissatisfied.Practical/managerial implications: Human resource practitioners, managers and team leaders need to recognise that employee’s moods influence the work pattern in the organisation and a clear job description and an appropriate career plan should exist.Contribution/value-add: Literature on the relationship between job description, career prospect and job satisfaction in the context of Mauritius is almost inexistent. This study will add to existing knowledge.

Purpose The purpose of this paper is to examine the relationship of business strategies with executive staffing of multinational companies (MNCs). Design/methodology/approach Based on in-depth interviews conducted with top executives of 22 MNCs’, the authors identify important connections between international business strategies and staffing orientation. The authors used the qualitative research approach of building theory from interviews; thus, creating theoretical propositions from empirical evidence. Findings The authors find that when the pressure for global integration is high, MNCs use more parent-country national (PCNs) (ethnocentric staffing) as against the use of host-country managers (HCNs) (polycentric staffing) when this pressure is low. Additionally, MNCs using a global strategy are more likely to use an ethnocentric staffing approach, those using a multi-domestic strategy use a polycentric approach and firms using transnational strategy adopt a mix of ethnocentric and polycentric approaches. Research limitations/implications Although the authors derive theoretical patterns based on rich qualitative data, their sample is relatively small and comprises mostly of French MNCs. Generalizability to a broader context is limited. However, the authors’ findings have critical implications for future research. Practical implications The authors’ findings provide critical managerial implications for MNCs in matching their HR strategies with business strategies. These are important for effective strategy implementation. Originality/value Although MNC staffing orientations have been studied for a long time, their relationship to international business strategies is still not clearly understood. The authors contribute to the literature by investigating the relationship between MNCs’ business strategy types with staffing orientations.

This study explores which metrics are considered important in measuring marketing performance in Turkish firms. In addition, the study examines the effects of sectoral differences and market dynamism, and the relationship between the importance attached to metrics and firm performance. The data collected from a sample of 145 Turkish firms via a structured questionnaire derived from the literature reveals that the most importance is attached to consumers’ attitudes metrics. Economic value added and customer lifetime value are the least important metrics in performance evaluation. No significant relationship occurs between the importance that executives attach to metrics and firm performance. Managerial implications and future research opportunities will be presented at the end. The study is, as far as is known, the first attempt at aiming to explore marketing metrics in Turkey, and one of a limited number of studies in emerging economies.

Digitalization has posed severe challenges to traditional businesses. Traditional firms are still not sure of the benefits of digitally engaging their customers. In contrast, the new-age firms have successfully leveraged digital media. This article examines the relationship between digital adoption by customers and customer lifetime value (CLV). This study analysed the mobile recharges by 13 million rural and urban prepaid telecom customers over 60 million transactions from January 2019 to June 2019 in the Indian telecom industry. The computed predictive CLV has been computed and compared across various customer segments (digitally engaged, partially digitally engaged and digitally unengaged customers). The studied data were statistically validated using the Kruskal–Wallis test. The data proved to be non-normally distributed as per the Kolmogorov–Smirnov test. The results supported that digital adoption helps increase customer engagement, loyalty and CLV. The study presents several managerial implications, such as digitally engaged customers being a surrogate for high value and more profitable customers. Also, digitally engaged customers are relatively more loyal, contributing higher CLV than digitally unengaged customers.
