Abstract
Describes a prospective study to establish the clinical outcome of patients who had undergone Doppler ultrasound for symptomatic suspected deep vein thrombosis, focusing on 142 consecutive patients referred for ultrasound investigation of their leg symptoms. Outcome measures included presence or absence of thrombus on ultrasound; re‐admission or outpatient investigations post ultrasound; and mortality at one year. Concludes that no patient with a negative Doppler ultrasound examination subsequently developed a thrombus in the following year although 18.8 per cent had died. Suggests that patients with leg symptoms of venous thrombosis but negative ultrasound should be followed up closely because of the likelihood of underlying pathology.

Abstract
Purpose
As social media have become very popular and an integral part of the world economy in recent years, identifying factors that influence consumers’ attitudes toward social media sites has become a major goal of many researchers in academia and industry. This paper aims to identify factors that predict consumers’ attitudes and intentions toward usage of Instagram, a relatively new social media tool. In addition, it examines the role of an important dimension of culture – individualism vs collectivism –to determine cultural influences on the adoption of social media in the USA (i.e. an individualistic culture) and Kuwait (i.e. a collectivist culture).
Design/methodology/approach
Data were collected from a convenience sample of undergraduate business and MBA students from Kuwait and the USA. To validate the measures for the constructs depicted in the conceptual model, the authors conducted an exploratory factor analysis using all items. They then conducted a confirmatory factor analysis to further evaluate the adequacy and validity of the measurement model. They also tested the hypotheses using structural equation modeling (SEM).
Findings
Out of the nine hypotheses that were tested for significance, the SEM results indicated that seven hypotheses were significant. The results indicated a non-significant result between perceived critical mass is not a predictor of perceived usefulness and social influence to attitude.
Research limitations/implications
The current study has some limitations that need to be recognized and can be used as guidelines for future research. First, college students represent only a portion of online users and may impact the external validity of our study. Hence, a more diverse sample with a broader range of ages, incomes, education levels, cultures and national origins would be advisable. Second, this study featured a dynamically continuous innovation (Instagram) rather than a discontinuous innovation. Third, other factors can be carried out to see other variables other than those described in this study to predict consumer’s attitude and intention to use the social media.
Practical implications
Cultural characteristics such as individualism/collectivism would seem to be potentially useful when segmenting countries. The results of the current study indicate that the modified model is applicable to a cross-national group of social media users. This study demonstrates the impact of cultural characteristics on various technology adoption. Hence, managers must be aware that countries can be grouped according to the type of cultural effect within each. Each social media category, clusters can be formed consisting of countries that are expected to have similar usage patterns based on technological capability and social norms. By understanding the factors that influence each cluster of countries, firms can design customized social media programs.
Social implications
This research provides valuable information to better understand the consumers’ attitudes and intentions toward the emerging social media landscape. Indeed, the popularity of social media has greatly changed the way in which people communicate in today’s world. In particular, Instagram has gradually become a major communication media for both social and business purposes. This research shed light into the factors that influence intentions to adopt social media across different cultures. It empirically examines the role of culture – individualism vs collectivism – by using two samples (i.e. Kuwait and the USA) to determine cultural influences on the adoption of social media in different cultures.
Originality/value
Using data drawn from Kuwait and US samples, this current study draws upon the theory of reasoned action (Fishbein and Ajzen, 1975) and the technology acceptance model (Davis, 1989). The results of the analysis indicate that the modified model is applicable to a cross-national group of social media users. Moreover, this study demonstrates the impact of cultural characteristics on various technology adoption constructs in the model.

Abstract
Purpose
The purpose of this paper is to examine the antecedents of organizational ambidexterity of foreign ventures in an emerging market. Organizational ambidexterity, the simultaneous pursuit of exploration and exploitation, represents a key innovation strategy. Yet, the driving factors of such innovation strategies for foreign ventures competing in emerging markets have been underresearched. In this study, unpacking the construct of organizational ambidexterity into two dimensions (i.e. the combined dimension [CD] and the balance dimension [BD]), the authors aim to investigate how firm-level and industry-level factors drive foreign ventures in pursuing exploration and exploitation and maximizing the benefits of both.
Design/methodology/approach
This study adopts the hierarchical multiple regression approach using a sample of foreign ventures operating in high-tech manufacturing industries in China.
Findings
The authors find that the firm-level factor of strategic flexibility leads positively to the CD of organizational ambidexterity, whereas the industry-level factor of technological turbulence has a significantly positive impact on the BD.
Originality/value
This study provides important insights into the driving factors of organizational ambidexterity for foreign ventures competing in emerging markets.

Abstract
Purpose
The purpose of this paper is to analyze possible causal relationships between exports, inward foreign investment and economic growth in Portugal and identify their direction.
Design/methodology/approach
The paper uses a three‐stage procedure based on unit root, cointegration and causality tests applied to annual data from 1977 to 2004.
Findings
The paper reveals that exports and FDI foster growth in the long‐run while in the short‐run there is a bi‐directional causal relationship between FDI and growth and a univariate causal relationship running from FDI to exports. FDI is viewed as a major determinant of economic growth, both directly and indirectly, via exports for both long and short‐run cases.
Practical implications
The results provide important corollaries in terms of policy implications and their relevance is far from being parochial. Some lessons in terms of domestic policies can be drawn by many countries that are now becoming EU members with economic structures and problems similar to those presented by the Portuguese economy in the 1980s.
Originality/value
This paper is the first of its kind to analyze the role of both FDI and exports in the Portuguese economy during the 1977‐2004 period, over which many efforts were developed in order to increase the external competition of the economy, in particular in the context of community structural frameworks. In order to reinforce the inflows of FDI, authorities should continue the progressive reduction of barriers to FDI and the reforms of the labour market which started in the early 2000s.

The purpose of this paper is to develop the notion of collaborative practice from theoretical and empirical bases.
Abstract
Purpose
The purpose of this paper is to develop the notion of collaborative practice from theoretical and empirical bases.
Design/methodology/approach
The research analysed the concepts of collaboration, reflective practice and the primary task. It also examined the ways of working of 18 primary schools in Wales where the level of student attainment in national test scores was high, despite the pupils experiencing considerable social and economic disadvantage.
Findings
From the conceptual analysis, we contend that established models of joint working accord insufficient significance to the work task and that reflective practice is essentially a social process, which requires a task focus to be successful. In the schools we studied, there was a particular way of working which we have called “collaborative practice”. It contributed substantively to their success. Collaborative practice is highly developed and inclusive joint working on a clearly defined main task, or primary task, in a reflective way. There are thus three elements to collaborative practice: collaboration, reflective practice and focus on the primary task. All three elements must be present for collaborative practice to be successful.
Originality/value
The collaborative practice model provides a straightforward framework for analysing work in schools. It also gives a secure foundation on which to base successful practice in educational institutions. The collaborative practice model therefore has implications for research and practice in educational settings, for the practice of educational leaders and managers, and for the professional development of those who work in schools.

Abstract
Purpose
Food industry players obtain the advantages of profits growth within the halal industry whereby the market is dynamic to generate profit. Hence, this study aims to analyse the perception of food manufacturers towards the adoption of the halal food supply chain (HFSC).
Design/methodology/approach
For this study, 103 halal food manufacturers in Malaysia were selected as respondents. Perceptions of respondents towards HFSC were recorded using a five-point questionnaire. The questionnaire was designed by authors and adapted from a previous study. The questionnaire was circulated by two experts with proficiency in this filed.
Findings
By conducting exploratory factor analysis, the study found the perception of food manufacturers, which is expected business benefits play an important role in the adoption of HFSC. Halal integrity becomes the second factor to lead the company to its adoption. Organizational readiness is the third factor that drives the company to adopt HFSC.
Research limitations/implications
Majority of the sample was responded by Bumiputera companies. The study suggests focussing the study for non-Bumiputera companies to examine their influence towards HFSC. Furthermore, future studies should explore different sectors of halal, such as pharmaceuticals, cosmetics, travel and tourism, logistics, finance and e-commerce. Moreover, ensuring the status of halal should be more emphasized in food chains; thus, the source of risk in HFSC should be explored to secure the integrity of halal.
Practical implications
The paper includes implications for the halal food industry, whereby the adoption of HFSC will contribute to the business benefits to create a more competitive advantage to the industry. Moreover, the implications of halal practice can create consumers’ trust on the halal product.
Originality/value
This paper fulfils an analysed need to study specifically on upstream parties by adopting HFSC.

Abstract
Purpose
The purpose of this paper is to consider a discrete‐time, Markov, regime‐switching, affine term‐structure model for valuing bonds and other interest rate securities. The proposed model incorporates the impact of structural changes in (macro)‐economic conditions on interest‐rate dynamics. The market in the proposed model is, in general, incomplete. A modified version of the Esscher transform, namely, a double Esscher transform, is used to specify a price kernel so that both market and economic risks are taken into account.
Design/methodology/approach
The market in the proposed model is, in general, incomplete. A modified version of the Esscher transform, namely, a double Esscher transform, is used to specify a price kernel so that both market and economic risks are taken into account.
Findings
The authors derive a simple way to give exponential affine forms of bond prices using backward induction. The authors also consider a continuous‐time extension of the model and derive exponential affine forms of bond prices using the concept of stochastic flows.
Originality/value
The methods and results presented in the paper are new.

Abstract
A sample of twenty‐six Mexican and fifty‐nine Canadian equities listed on the New York Stock Exchange are examined to determine whether these foreign equities outperform the S&P 500 as a result of the North American Free Trade Agreement of 1994. Data are tested for significant differences in performance before and after the introduction of NAFTA during the period 1980‐2000. Findings show no significant post‐NAFTAdifference in the three‐year performance of the Mexican equities. However, the post‐NAFTA sample of Canadian equities significantly outperformed the S&P 500 by 28.8 percent, perhaps suggesting a NAFTA‐related wealth effect for the Canadian firms.
