How fundamental and supplemental interactions affect users’ knowledge sharing in virtual communities? A social cognitive perspective
Authors: Zhou Junjie , Zuo Meiyun , Yu Yan , Chai Wen 
Published: September 2014

Purpose– The purpose of this paper is to investigate the effects of the environment of a virtual community (users’ interactions inside and outside of a community which are defined as the fundamental and supplemental interaction (FI and SI), respectively) on its users’ knowledge sharing (KS) and the underlying cognitive mechanism.Design/methodology/approach– A survey was conducted among the users who had experience of participating in a domain knowledge specific online community. A total of 479 valid observations were collected. Structural equation modeling was used to test the research model and hypotheses.Findings– The empirical results show that the fundamental interaction (FI) not only directly affects users’ knowledge acquisition (KA) and contribution, but also indirectly affects users’ KA and contribution partially through the users’ self-efficacy and outcome expectation. While the supplemental interaction (SI) negatively affects users’ KA, it positively affects the users’ knowledge contribution and this effect is also partially mediated by the users’ self-efficacy and outcome expectation. The mediators of self-efficacy and outcome expectation play distinct role on users’ KA and contribution in virtual communities (VCs).Originality/value– This research conceptualizes the users’ interaction inside and outside of a particular virtual community as FI and SI, respectively, and reveals the mechanism how they affect users’ KA and contribution. The results shed light on the literature of KS in VCs and extend social cognitive theory's application into a complex environment with blended interactions in a virtual world. The research also provides insights for virtual community designers, administrators and users.
Managerial implications in solution business studies: analysis of type of relevance addressed
Authors: Tapio Salminen Risto , Oinonen Minna , Haimala Juha 
Published: September 2014

Purpose
– The purpose of this paper is to gain knowledge on the character of managerial implications within business-to-business (B2B) marketing, in terms of type of relevance addressed in research articles on solution business and integrated solutions.

Design/methodology/approach
– Use of Jaworski’s framework on role-relevance to classify the type of relevance addressed in 29 journal articles. A systematic literature review on solution business preceded the selection of articles and a concern to include different journal categories.

Findings
– Managerial implications in the studied articles within solution business do not seem to emphasize role-relevance particularly; they rather address applicability of findings on a company level and for B2B marketing in a more general sense. The majority of implications for practice are framed to have an impact on “present actions”. Managerial knowledge needs are dominantly addressed by “empirical findings” or “frameworks”. The dominating managerial core tasks addressed are “transformer of marketing” and “marketing strategy”.

Research limitations/implications
– There do not seem to be studies with managerial implications addressing future actions and thinking; providing instruments, methods or models that are role- relevant; focusing on the challenges of a “coordinator”, “strategist” or “performance controller”. The focus on solution business limits the generalizability of findings.

Practical implications
– Results suggest that implications for practice potentially would benefit from being written in the form of explicit recommendations; targeted to a particular managerial role; and increasingly developed when it comes to proposed frameworks for them to be useful for managers in industrial marketing.

Originality/value
– This is one of the first studies to systematically examine the character of managerial implications by categorizing results in accordance with a framework specifically addressing role-relevance.
The theory/practice gap in B2B marketing: reflections and search for solutions
Authors: Gummesson Evert 
Published: September 2014

Purpose– The purpose of this study was to suggest pragmatic ways of dealing with the business-to-business (B2B) theory/practice gap.Design/methodology/approach– Reflecting on experience both as a researcher and practitioner.Findings– B2B marketing is characterized by complexity. There is no straight way to harmonize the relationship between its theory and practice but there are ways to make the two benefit from each other. A dilemma is that academics and practitioners are rewarded for different types of achievements.Research limitations/implications– Scholars can be made aware of the need for close involvement through action research and case theory to secure access to high-quality data in a complex B2B reality, and to their mission to contribute better real world based theory.Practical implications– The article can make practitioners aware of the value of grand theory to improve the pragmatic use of mid-range theory as it materializes in models, checklists and heuristics.Originality/value– The simultaneous emphasis on explicit and tacit knowledge in both theory generation and practice, and a framework of theory generation that sorts out substantive, mid-range and grand theory relationships.
Conceptualizing for managerial relevance in B2B research: a grounded theory approach
Authors: Gustavsson Bengt , Åge Lars-Johan 
Published: September 2014

Purpose
– This study aims to formulate recommendations for business-to-business (B2B) researchers, with the potential to increase the extent to which B2B research is relevant to managers.

Design/methodology/approach
– These recommendations are derived from and inspired by the grounded theory methodology.

Findings
– In this article, we argue that conceptualizations which are potentially relevant to managers are those that discover new perspectives, simplify complexity, enable managers to take action and have an instant grab. To accomplish this as researchers, the authors emphasize fostering a beginner’s mind, creating umbrella models, increasing the level of abstraction of concepts and finding the core process in data.

Originality/value
– In this article, we translate the basic principles within the grounded theory methodology into more general recommendations that can be used by B2B researchers.
Accentuate the positive: how identity affects customer satisfaction
Authors: Ghosh Chowdhury Tilottama , Desai Kalpesh Kaushik , Bolton Lisa 
Published: September 2014

Purpose
– The purpose of this research is to address an important gap in identity research – how does consumer identity affect satisfaction following an unambiguous product experience.

Design/methodology/approach
– Two experiments were conducted involving a product experience scenario and a service recovery encounter.

Findings
– Study results demonstrate that experience valence moderates the impact of identity on customer satisfaction. Specifically, we find that identity improves satisfaction with a positive (but does not increase dissatisfaction with a negative) experience, and this effect arises via enhanced performance perceptions under positive experience rather than expectations.

Research limitations/implications
– Our research investigates whether the prior research argument that identity is a powerful and “sticky” source of brand evaluation is robust to product experience. Specifically, we extend the disconfirmation paradigm of satisfaction by identifying identity as a driver of satisfaction and by testing whether identity effects emerge via biased perceptions of performance or altered expectations.

Practical implications
– Our findings offer interesting managerial implications in terms of using identity marketing to enhance customer satisfaction with positive experiences and to increase the effectiveness of recovery from brand failures, but identity marketing cannot shield a brand from negative product experience.

Originality/value
– To our knowledge, this research is first to demonstrate the joint effects of identity and experience information on satisfaction using two different identities and settings.
Effects of show windows on female consumers’ shopping behaviour
Authors: Jain Varsha , Takayanagi Mika , Malthouse Edward Carl 
Published: September 2014

Purpose– The purpose of this study if to investigate the effects of show windows on shopping behaviour among female consumers to provide insights that a manager can use to encourage purchase behaviour.Design/methodology/approach– On the basis of 20 in-depth interviews, we developed a survey, which we administered to female consumers (n= 209). The survey was based on a stimulus–organism–response framework. Each respondent was exposed to an image of a show window (images were taken from apparel departments of well-known department stores) and rated her perceptions of the window and intentions to purchase items sold in the store.Findings– Using factor analysis, we identify five components of the show window: social, hedonic, informational, image and “feel-good” factors. The first four factors are aggregated into a “show window” metric, which is shown to influence purchase intentions; this influence is fully mediated by the feel-good factor. The image factor and the social and hedonic factors each significantly influence the feel-good factor.Practical implications– When developing show windows, brand managers should aim to touch on all factors of the show window to make shoppers “feel good”; these positive feelings might intensify shoppers’ purchase intentions.Originality/value– This study identifies five factors that make up consumers’ perceptions of show windows. It shows that exposure to a show window affects consumers’ purchase intentions, and that this influence is determined primarily by the extent to which consumers “feel good” about the store.
Potential agency problems in European club football? The case of UEFA Financial Fair Play
Authors: Schubert Mathias 
Published: September 2014

Purpose– With the licence season 2013/2014 onwards Union of European Football Associations (UEFA) Financial Fair Play (FFP) fully came into force. Among other things, FFP demands from the clubs to operate within their own revenues in order to counteract the increasing over indebtedness in European club football. The purpose of this paper is to cast further light on the relationship between UEFA and the clubs as the main actors of FFP and to derive implications to UEFA to improve the efficacy of this regulatory intervention.Design/methodology/approach– This paper explicitly examines the case of FFP from an agency theory perspective. A positivist agency approach is applied in order to describe and explain (potential) problems in the relationship between UEFA and the clubs.Findings– The paper demonstrates that the relationship between UEFA and the clubs corresponds in many aspects to a classic principal-agent problem. A potential conflict of interest between both actors is outlined which together with asymmetric information creates incentives for opportunistic behaviour on the part of the clubs. The necessity of a stronger emphasis and communication of the economic and sport ethical legitimacy of FFP is detected.Practical implications– It is suggested that UEFA should consider taking a more proactive stance and endeavour to prevent non-compliance not only by limiting the opportunities to do so but also by providing information as well as education.Originality/value– FFP is supposed to have ground-breaking consequences for European club football. This is the first paper to systematically examine (potential) agency problems inherent in FFP.
Dynamic leadership – a leadership shortage solution
Authors: Tucker Elissa , Lam Sue 
Published: September 2014

Purpose
– The purpose of this research paper is to explore how organizational leadership style is related to employee leadership skills, leadership and business trends, as well as leadership practices.

Design/methodology/approach
– In total, 547 participants representing a variety of industries and organization sizes completed an online survey on the current state of leadership at their organizations. We compared the responses of participants working in organizations using a traditional leadership style (n = 121) with those in organizations with a dynamic leadership style (n = 105).

Findings
– Consistent with hypotheses, the results show that the traditional, hierarchical and command-and-control style of organizational leadership is associated with larger leadership skills gaps, while a more dynamic, all-inclusive and collaborative leadership style is associated with smaller leadership skills gaps. Specific business trends and leadership practices partially explain the association between organizational leadership style and organizational leadership shortages. These factors provide guidance for human resources practitioners looking to set priorities and plans for fostering dynamic leadership within their organizations.

Originality/value
– This study provides insights into why the leadership deficit endures and what organizations can do to put the issue to rest. This research is unique in that it goes beyond identifying and quantifying specific leadership skills gaps to also reveal which factors may be driving these leadership deficits. This research also isolates which organizational practices and leadership approaches are associated with smaller leadership skills gaps.

Published: September 2014

AbstractMaintaining current, relevant curriculum in undergraduate Food Microbiology courses is essential for training future experts in food quality and safety. Having an understanding of the fundamental techniques (for example, polymerase chain reaction [PCR]) that are used in the food industry and regulatory agencies is critical for students entering the workforce. The purpose of this study was to assess the efficacy of integrating molecular methods into an undergraduate Food Microbiology course in both lecture and laboratory settings. Modules on PCR and pulsed‐field gel electrophoresis (PFGE), both of which are currently used by government agencies and the food industry to investigate the presence and persistence of foodborne pathogens, were developed, introduced, and evaluated among 269 students over 4 y. Multiple teaching and learning styles were incorporated through (i) traditional lecture format on the basics of PCR and PFGE; (ii) hands‐on group activities to build upon the lecture instruction; (iii) performing PCR and PFGE in the laboratory; and (iv) group discussions to analyze results from laboratory exercises. Pre‐ and postinstruction evaluations revealed significant increases in understanding and application of both methods in lecture and laboratory settings as demonstrated by 0.60 and 0.51 mean normalized gains for respective PCR and PFGE lectures and 0.50 and 0.56 mean normalized gains in respective labs. Academic year significantly impacted score improvement, potentially due to hidden factors, such as previous exposure to material and student aptitude. This study provides the platform for successful introduction of molecular techniques in an undergraduate Food Microbiology course. The guidelines and materials developed by our group are publicly available for use by other institutions.
Food Science Education and the Cognitive Science of Learning
Authors: Chew Stephen L. 
Published: September 2014

AbstractIn this essay, I argue that the traditional view of teaching, that the teacher's responsibility is to present information that students are solely responsible for learning, has been rendered untenable by cognitive science research in learning. The teacher can have a powerful effect on student learning by teaching not only content, but how to study and think about information. Student learning is a shared responsibility between teacher and students, and effective teaching is much more challenging than traditionally believed.
Magnetic resonance imaging aspects of giant‐cell tumours of bone
Authors: Pereira Helcio Mendonça , Marchiori Edson , Severo Alessandro 
Published: September 2014

AbstractIntroductionThis study aimed to describe the magnetic resonance imaging (MRI) features of giant‐cell tumours of bone.MethodsWe analysed the clinical and MRI features of patients diagnosed with giant‐cell tumours of bone confirmed by histopathology at our institution between 2010 and 2012.ResultsThe peak incidence was between the second and third decades of life. There was no gender predominance. The most frequent locations were the knee and wrist. Pain and swelling were the prevailing symptoms. Fifty‐one per cent of the patients were found to have associated secondary aneurysmal bone cysts on histopathology. On MRI, lesions demonstrated signal intensity equal to that of skeletal muscle on T1‐weighted images and low signal intensity on T2‐weighted images in 90% of cases. In gadolinium‐enhanced T1‐weighted images, 76.6% of cases demonstrated heterogeneous enhancement. We observed cystic components involving more than 50% of the lesion in 17 cases (56.6%). There was extra‐osseous involvement in 13 cases (43.3%).ConclusionMRI offers a valuable diagnostic tool for giant‐cell tumours of bone. Contrast‐enhanced MRI can distinguish between cystic and solid components of the tumour. MRI is also the imaging modality of choice for evaluation of soft‐tissue involvement, offering a complete preoperative diagnosis.
Expression of programmed death 1 is correlated with progression of osteosarcoma
Authors: Zheng Wenjie , Xiao Hong , Liu Huan , Zhou Yue 
Published: September 2014

Accumulating bodies of evidence indicate that immune dysregulation plays a key role in the development of osteosarcoma (OS). Programmed death 1 (PD‐1) is a surface receptor expressed on activated and exhausted T cells, which mediate T‐cell inhibition upon binding with its ligand. Researches on PD‐1 and OS remain extremely limited. Here, we investigated whether PD‐1 could be involved in the development of OS. Expression of PD‐1 was measured by flow cytometry on peripheral CD4+ and CD8+ T cells from 56 OS cases and 42 healthy controls. Data revealed that percentages of PD‐1 were significantly upregulated on both peripheral CD4+ and CD8+ T cells from OS patients (p < 0.001 and p < 0.001, respectively). Patients with different tumor locations did not present obvious variations in PD‐1 level. However, patients with metastasis showed significantly higher level of PD‐1 on CD4+ T cells than those without metastasis (p < 0.001). Furthermore, PD‐1 expression on CD4+ T cells started to increase in stage III, whereas PD‐1 expression on CD8+ T cells started to increase in stage II. In addition, patients with pathological fracture were observed to have elevated PD‐1 on both CD4+ and CD8+ T cells. These data suggest that PD‐1 is involved in the pathogenesis of OS, especially in the progression of disease.
Chronic lymphocytic leukaemia, monoclonal B‐lymphocytosis and pregnancy: five cases, a literature review and discussion of management
Authors: Hamad Nada , Kliman David , Best O. Giles , Caramins Melody , Hertzberg Mark , Lindeman Robert , Porter Ric , Mulligan Stephen P. 
Published: September 2014

SummaryChronic lymphocytic leukaemia (CLL) occurs rarely with pregnancy and monoclonal B‐Lymphocytosis (MBL) has not previously been described in this setting. CLL is predominantly a disease of the elderly and affects men twice as often as women and hence only an estimated 2% of patients are females of childbearing age. We identified only five reported cases of CLL in pregnancy in the literature. We describe two additional cases, plus three other women with CLL dealing with pregnancy‐related decisions. We review the literature and discuss proposals for management and issues that arise in this relatively uncommon occurrence. In contrast to many other haematological malignancies where longer remissions are typically associated with a lower risk of relapse, most patients with CLL who require treatment will ultimately relapse with current therapy. This complex setting requires careful consideration and well informed patients to assist with decisions related to pregnancy.

SummaryBackgroundShellfish allergy in Singapore is highly prevalent, and shrimp allergy is the most common.ObjectiveThis study aims to evaluate the clinical characteristics and immunological phenotype of shellfish allergy in this population.MethodsPatients with self‐reported shellfish allergy were recruited from outpatient clinics of three large hospitals and from a population survey. Open oral food challenges (OFC) to glass prawn (Litopenaeus vannamei) and tiger prawn (Penaeus monodon) were carried out on all patients except for those who had a history of severe anaphylaxis. Skin prick tests (SPT) and specific IgE to crude and recombinant allergens were carried out to evaluate shrimp and dust mite sensitization. Immunoblots were used to assess IgE‐binding proteins.ResultsThe 104 patients recruited were categorized into shellfish allergic (SA) when OFC was positive or had a history of severe anaphylaxis (n = 39), shellfish tolerant (ST) when OFC was negative (n = 27), and house dust mite positive controls (HDM+) who were ST (n = 38). Oral symptoms (87.1%) were the predominant clinical manifestation. Positive challenge doses ranged from 2 to 80 g of cooked shrimp, with 25/52 patients reacting to either one or both shrimps challenged. The presence of specific IgE to shrimp either by SPT and/or ImmunoCAP® assay provided diagnostic test sensitivity of 82% and specificity of 22.2%. The inclusion of specific IgE to shrimp tropomyosin and IgE immunoblots with shrimp extracts did not improve the diagnostic proficiency substantially.Conclusions and Clinical RelevanceThis study highlights the predominance of oral symptoms in shrimp allergy in tropical Asia and that a high provocation dose may be necessary to reveal shrimp allergy. Furthermore, specific IgE diagnostic tests and immunoblots were of limited use in this population.
