Selecting the individual numerical scale and prioritization method in the analytic hierarchy process : a 2-tuple fuzzy linguistic approach

The validity of the priority vector used in the analytic hierarchy process (AHP) relies on two factors: the selection of a numerical scale and the selection of a prioritization method. The traditional AHP selects only one numerical scale (e.g., the Saaty scale) and one prioritization method (e.g., the eigenvector method) for each particular problem. For this traditional selection approach, there is disagreement on which numerical scale and prioritization method is better in deriving a priority vector. In fact, the best numerical scale and the best prioritization method both rely on the content of the pairwise comparison data provided by the AHP decision makers. By defining a set of concepts regarding the scale function and the linguistic pairwise comparison matrices (LPCMs) of the priority vector and by using LPCMs to unify the format of the input and output of AHP, this paper extends the AHP prioritization process under the 2-tuple fuzzy linguistic model. Based on the extended AHP prioritization process, we present two performance measure criteria to evaluate the effect of the numerical scales and prioritization methods. We also use the performance measure criteria to develop a 2-tuple fuzzy linguistic multicriteria approach to select the best numerical scales and the best prioritization methods for different LPCMs. In this paper, we call this type of selection the individual selection of the numerical scale and prioritization method. We also compare this individual selection with traditional selection by using both random and real data and show better results with individual selection.

Need to know : lessons from Sino-Australian business negotiators on the importance of guanxi, emotions and generational differences in Chinese negotiation behaviour

The forces of globalisation over the last few decades have created opportunities for intemational business as never before, whilst leaving no organisation immune to competition. With the Global Financial Crisis impacting the world economy, the BRIC economies as a group - Brazil, Russia, India and China, have steadily benefited from continuing growth in 2008 and 2009 (Bhattacharya, Hemerling and Waltermann,2010). Despite China being a key international trading partner for Australia, the number of successful joint ventures and negotiations between the two countries remains limited. A closer examination of the international business interactions between Australia and China is thus urgently needed. When negotiating with the Chinese, Western managers may not always be aware of what they are really negotiating for. To be successful, they have to be equipped with the 'specialised knowledge', a form of 'tacit or implicit knowledge', which comes with experience (Nonaka, 1994, Pavesi, 2003) in communicating and negotiating with their Chinese counterparts. The Chinese way of business negotiation can challenge the logic of Western business thinking. This, coupled with possible generational differences or changes in the Chinese business counterpart's way of doing business, means we must try to understand the business communication and negotiation process from not only the Western but also the Chinese perspective. In particular, in addition to the contextual (Phatak, & Habib, 1996; Risberg, 1997), social (Ghauri, & Fang, 2001), and cognitive factors (George, Gareth, & Gonzalez, 1998) focused on by past researchers, the intangible aspects of negotiation must also be considered. These include trust, reputation, relationship quality (guanxi in the case of the Chinese), and the moods and emotions that shape the processes and outcomes of communication and negotiation (Griffith, 2002; Hartel & Ma, 2006; Ma & Hartel 2005; and Zhao & Krohmer, 2006). This paper reports on a qualitative investigation of the communication processes occurring in negotiations between Australian and Chinese managers and entrepreneurs. The examination is based on a theoretical framework looking at emotions and culture from an affective events theory (AET) perspective. Both interview and focus groups techniques were used. Findings identified guanxi, core to relationship development and maintenance in Chinese culture, together with emotions as major determining factors of negotiation outcomes. Findings also suggest there are generational differences in attitudes among Chinese managers with Gen. X and Gen. Y placing a different emphasis on guanxi in business. These findings suggest that the popular advice to people doing business in China is out of date.

Management as a contextual practice : the need to balance science, skills and practical wisdom

This paper contributes to the debate regarding whether or not management is, or should become, a profession. Using the principles of dialectic logic, arguments for the thesis that management is a profession and the antithesis that management is more akin to an art or a craft are critically reviewed. Aristotle’s intellectual virtues episteme (science), techne (skills) and phronesis (practical wisdom) are introduced as a synthesis to this debate. Rather than characterizing management as a profession, it is argued that management is a contextual practice that requires a blend of all three intellectual virtues.

Do we need to flick the switch? The need for a broader conceptualization of iatrogenic course aggravation in clinical trials of bipolar disorder?

The term ‘switching’ is often used in bipolar disorder when describing polarity changes in bipolar disorder, but this term is ambiguous and imprecise, and is sometimes used interchangeably with the term ‘cycling’. Furthermore, polarity changes in bipolar disorder can be understood in different ways, because their clinical manifestations range from the emergence of subthreshold symptoms to a full episode of the opposite pole. Besides the need to tighten the meaning of the term ‘switching’, this paper also argues that switching does not adequately describe the complex phenomena that occur with course aggravation of bipolar disorder, such as alteration in episode frequency or amplitude. A more-fine grained approach to course aggravation in bipolar disorder is proposed, which incorporates trans-polar switching, index polarity aggravation, as well as alterations in episodic amplitude, episodic duration, and interepisode length. This approach has the potential to capture a broader, more fine-grained and clinically relevant picture of the process of aggravation of the bipolar cycle.

Pilot Study of clinician attitudes to insulin pump therapy: international differences and the need for a greater understanding of the patient perspective

OBJECTIVES: To identify and survey health care professionals (HCPs) attitudes to insulin pump therapy (CSII).

METHODS: Eight specialists were interviewed to explore the attitudes and beliefs about CSII. Responses were analysed thematically and used to inform the design of a new 22-item questionnaire: the Attitudes to Pump Therapy (APT) Survey. The APT was pilottested among 95 HCPs (54% male; 75.5% diabetologists/DSNs, 13.8% general practitioners) at the International Diabetes Federation (IDF) conference, 2006. Results were analysed using non-parametric statistics with bonferroni correction.

RESULTS: Analyses of interview data identified 9 themes: biomedical, perceived control of care/diabetes, technology, quality of life, financial resources, training, education & support, suitability, and evidence-base. Items were designed to reflect these themes with responses scored on a 5-point Likert scale (strongly agree—strongly disagree). No statistically significant differences
were found by gender, HCP speciality, country (and continent) of origin or proportion of patients using CSII. Most notable differences were found in relation to gross domestic product (GDP) and the potential for pump therapy to achieve tight blood glucose control (lower GDP = more agreement: p = 0.001), and result in diabetic ketoacidosis (DKA) (lower GDP = less agreement: p < 0.005). Ranked mean scores showed a split between biomedical/clinical items (N = 11) and items concerned with patient experience (N = 11). Attitudes about biomedical/clinical issues were generally clear (i.e. for 7/11 items, the mean score was “agree”) but less decisive about patient experience (i.e. for 8/11 items, the mean score was “neither agree nor disagree”).

CONCLUSION: Few subgroup differences existed, but those that did may be explained by lack of access to treatment (directly corresponding to GDP). Clinicians’ were generally clear in their attitudes regarding biomedical aspects but less so regarding patient experience. Research focusing on patient-reported outcomes is likely to offer clinicians a greater understanding of the patients’ perspective of insulin pump therapy.

Is it green marketing, greenwash or hogwash? We need to know if we want to change things

This paper explores the issue of sustainable marketing practices; more explicitly: whether or not marketers will trade off profitability for the environment. To examine this notion, a question was asked of certified practicing marketers (CPM) during a webinar on hot topics in marketing. Results show that the long term environment is still at risk as marketers are unwilling to trade off profits for sustainable practice. This implies that social marketing activities may require more intense efforts to redress this situation. These activities may need to include upstream social marketing that will require underpinning research for strategic direction.

Is there a need to reform the corporate class action procedure in Australia?

This article argues for a need to reform the corporate class action procedure in Australia. The reason is that the statutory procedure for an “opt out” class action is beginning to appear more like an “opt in” class action. The confusion relates to the poor drafting of Part IVA of the Federal Court of Australia Act 1976, which contains the class action procedure. The involvement of a commercial litigation funder has also contributed to the complexity in the interpretation of the law. The article provides a review of why s 33J and s 33E are conceptually difficult to apply. It highlights the key areas that require legislative amendments in order for the class action procedure to operate more effectively.

Nonpharmacologic interventions need outcomes for evaluating complex interventions in rheumatic diseases

Introduction. Nonpharmacologic interventions are themselves complex and are often combined with drugs and other interventions in the treatment of rheumatic diseases. Therefore, overall strategies for treatment are complex interventions. These should be evaluated regarding their processes and outcomes.
Methods. The CARE network, an international organization of health professionals (physicians and nonphysicians) and patients conducted a survey in 2008 to identify core outcomes in the ICF perspective, completed with a second survey (2009–2010) with patients in routine practice. These surveys have provided new information about domains to investigate as a basis for evaluating complex interventions.
Results. Outcome Measures in Rheumatology Clinical Trials (OMERACT) participants in this Special Interest Group agreed that current outcomes used in pharmacological research are not sufficient if the nonpharmacologic independent or combined contributions are to be assessed; other domains need to be addressed. This is an area of interest for further development.
Conclusion. Recommendations are proposed to develop research in the area of outcome for evaluation of complex interventions in rheumatic diseases.
