Institutional entrepreneurs
Authors: Wahid Fathul , Sein Maung K. 
Published: March 2013

PurposeWhile institutional theory is used widely in the information system (IS) literature to study implementation of systems, the actual process of institutionalization has received less attention. The purpose of this paper is to address this gap in the literature by using three concepts drawn from the theory, namely, institutional isomorphism, institutional logic and institutional entrepreneurship, and the interplay between them to explore the role of the dominant institutional entrepreneur in the institutionalization of a public system, as an instance of e‐government initiatives.Design/methodology/approachIn an interpretive case study, this study examined the institutionalization process of an e‐procurement system over a four‐year period (2007‐2011) in the Indonesian city of Yogyakarta.FindingsThis study reveals that different institutional isomorphism mechanisms emerge during the process and institutional logics evolve over time. More interestingly, it uncovers the dominant role of an institutional entrepreneur, the city's mayor, who mobilized resources and support to drive the institutionalization process. At the beginning stage, institutionalization is best described as a process of instilling values, cultivated by the mayor, followed by a process of creating reality through a typification process, whereby the e‐procurement system is embedded in the existing practices and institutionalized.Research limitations/implicationsAs an interpretive study, the findings are generalized to theoretical concepts rather than the population. The interrelationship between the three concepts of institutional theory represents plausible rather than deterministic links. It also offers practical insights, such as e‐procurement implementation strategy.Originality/valueThis paper goes beyond simply using institutional theory as an interpretive lens by examining the interrelationship between the mechanisms of institutionalization. It shows that the main catalyst of the institutionalization process is the institutional entrepreneur who managed the institutional isomorphism and was instrumental in changing the institutional logic. It also presents lessons from a successful case where corrupt practices were highly institutionalized at the beginning but were decreased through the system.

Published: March 2013

PurposeThe purpose of this study is three fold: to provide a preliminary exploration of meeting planners' use and perceived usefulness of the different types of social media; to examine why meeting planners use social media and; to investigate the perception of adopting the social media, especially as perceived critical mass impacts the adoption of social networking media.Design/methodology/approachData were collected from the members of a professional association for meeting professionals in the Southwest US using an online self‐administered questionnaire. A total of 510 members received an invitation to take the survey and 120 responses were received, representing a 23.5 percent response rate. Descriptive analysis, discriminant validity, reliability and path analysis were used to estimate the relationships between the five constructs: perceived critical mass, usefulness, ease of use, attitudes and intention to use social network media in the future.FindingsThe most commonly preferred social network sites were Facebook (29 percent), LinkedIn (15 percent), YouTube (13 percent), Twitters (11 percent) and My Space (11 percent) and the social networking media rated most useful were Facebook (mean=3.7), LinkedIn (mean=3.1), YouTube (mean=3.0), Blogs (mean=2.7), Webinars (mean=2.6) and Twitter (mean=2.5), The top three reasons for using social media were: to communicate with other planners easily and quickly through chat or discussion boards (80.4 percent), to share queries, problems, solutions and opinions with other meeting planners (70.1 percent) and to get feedback from attendees after meeting/event/convention (69.9 percent). Additionally, the path model used in the analysis indicated that perceived critical mass not only directly influences intention to use social network media but also indirectly affects attitude toward using social media and intention to use social media simultaneously through perceived ease of use and perceived usefulness.Originality/valueEven though the social networking media has previously been used by many meeting planners to find information, few research studies have explored the meeting planners' perception of social networking media and what factors may have an effect on meeting planners' adoption of using social network media. This study provides a preliminary empirical analysis of meeting planners' perception of these tools and the factors that influence their utilization.
Factors influencing customer acceptance of kiosks at quick service restaurants
Authors: Kim Jungsun (Sunny) , Christodoulidou Natasa , Choo Yunjeong (Clara) 
Published: March 2013

PurposeThis study aims to explore: the impact of customers' previous experience on their likelihood of using kiosks at quick service restaurants (QSRs); a mediating role of customer readiness (i.e. role clarity, ability, extrinsic motivation, intrinsic motivation) between customers' previous experience and their likelihood of using kiosks; and a moderating effect of gender in the relationships among customers' previous experience, readiness, and likelihood of using kiosks.Design/methodology/approachA total of 614 complete responses were obtained through an online survey. Structural equation modeling was developed and tested.FindingsThe results demonstrated that extrinsic motivation in using SSTs directly influenced the likelihood of using kiosks, and previous experience with SSTs indirectly influenced the likelihood of using kiosks through customer readiness in both male and female groups. This study also revealed that both male and female respondents who perceived their roles in using SST more clearly were more likely to use kiosks at QSRs. However, their perceived ability and levels of intrinsic motivations did not significantly influence the likelihood of using kiosks in both groups. Overall, gender did not play a significant moderating role in the relationships among experience, readiness, and likelihood of using kiosks at QSR.Originality/valueSince very few studies have investigated the kiosks adoption at QSR settings, the findings and suggestions from this study will provide practical insight for QSR operators. Future research could attempt to draw a comprehensive kiosk acceptance model by incorporating the current study's framework with other demographic variables or other antecedent variables.
Participant observation at events: theory, practice and potential
Authors: Mackellar Joanne 
Published: March 2013

PurposeThe purpose of this paper is to review the techniques involved in participant observation and to assess the strengths and weaknesses of the method as related to event research.Design/methodology/approachA review of the literature examines applications of the research method and discusses the steps of the research cycle. Using the example of the Swell Sculpture Festival, participant observation is demonstrated to be a highly appropriate method to gather data on interactions and relationships through the recording of behaviour, conversation and experience in situ.FindingsParticipant observation has been used to inform the development of management strategies, including management of crowd behavior, public risk and safety.Research limitations/implicationsThe paper suggests that methods of participant observation can be used to gain a deeper understanding of social dynamics of audiences and the affective dimensions of their behaviour. It is suggested that the method is highly appropriate to the context of event environments, where the use of surveys can interrupt the flow of the event experience for audiences, or be made impossible by the structure of the event.Practical implicationsThe case study demonstrates the application of the methodology by event managers to gaining a better understanding of audience behaviour and expectations.Originality/valueThe methods of participant observation, as part of the broader qualitative research paradigm, are somewhat neglected by event researchers, despite their utility in other disciplines such as retail, education and tourism. This paper highlights the potential of the method for use in future studies of events and their audiences.
Management accounting change in an Egyptian organization: an institutional analysis
Authors: Youssef Mayada A. 
Published: March 2013

PurposeThe purpose of this paper is to investigate the process of management accounting change within an Egyptian organization that implemented an extranet.Design/methodology/approachOld institutional economic (OIE) theory and Hardy's model of power mobilisation are chosen as a theoretical framework to inform the analysis of the case.FindingsThe results show that the extranet facilitated changes in information availability and business process re‐design. The findings confirm that management accounting practices have changed in the case under study and show how management accountants have become more involved in planning and control. The case highlighted some factors that facilitate the natural processes of routinisation and institutionalisation over time.Research limitations/implicationsIt could be argued that one limitation of this research is related to the gap between the change in leadership in TexCo (1993) and the timing of the visits (2001, 2002, 2003 and 2005). However, this problem has been minimized by crosschecking memories of events through interviews. Another limitation of this study is that the author was not allowed to review some of the financial documents in TexCo. However, the author tried to verify the financial figures given by them through inter‐subject checking.Originality/valueThis paper fills a gap in the literature as it focuses on the process of management accounting change associated with the implementation of business‐to‐business (B‐to‐B) e‐commerce. The findings, indicate that the B‐to‐B e‐commerce has facilitated the change in the management accounting practices towards decision support and control. Implementing the B‐to‐B e‐commerce system in TexCo facilitated greater control over inventory and invoicing. It improved the planning process through providing the accountants with accurate and real time information about sales, receivables, cash collection and inventory turnover. The system also facilitated the settlement process, the performance evaluation of TexCo's exhibitions; and saved the time and effort of the accountants during the stocktaking process. The case suggested that there are some factors that may facilitate the processes of routinisation and institutionalisation.
A profile of violent female offenders in secure psychiatric care
Authors: Evans Rebecca , Hollin Clive , Long Clive 
Published: March 2013

PurposeThis study aims to explore whether female psychiatric homicide offenders form a distinct group when compared to women who have committed other types of serious violent offences.Design/methodology/approachA range of background and psychological characteristics for 13 homicide and 13 non‐homicide offenders, matched by date of birth, were compared. In addition, change in psychological and behavioural presentation after 12 months stay at a registered charity trust hospital in England was considered.FindingsThe findings indicate that the two groups were broadly similar, although the non‐homicide violent offenders had somewhat more troubled backgrounds. The two groups responded similarly to treatment, although the homicide offenders displayed significantly fewer aggressive risk behaviours whilst in care.Practical implicationsIt is concluded that the two groups present with similar needs, with indications of greater treatment need for polynomial substance misuse for the non‐homicide group.Originality/valueThis is the first study to compare directly these two specific groups of violent female offenders, considering both static background variables, and behaviour whilst in security.
Forensic psychological public safety risk assessment integrated with culturally responsive treatment for juvenile fire setters: DSM‐5 implications
Authors: Johnson Ronn , Beckenbach Heidi , Kilbourne Samantha 
Published: March 2013

PurposeThis paper aims to present an overview of a variety of risk assessment issues that are of particular relevance for work with juvenile fire setters in clinical and forensic settings. The paper seeks to consider Juvenile Fire Setting (JFS)‐Youthful Misuse of Fire (YMF) across a broad array of clinical domains, including developmental, prognostic, and the diagnostic utility anticipated by using the DSM‐5. National standards and risk assessment levels are to be examined.Design/methodology/approachThe paper includes a comprehensive review of the research and practices related to juvenile fire setters. This review included assessment and intervention resources that are used in diverse practice environments. The authors reviewed the literature to establish a nexus between risk assessment and community‐based interventions which were illustrated by a nationally recognized YMF mental health program (FATJAM).FindingsThe paper provides empirically‐based insights into key issues for working with these forensic cases. It offers discussion regarding diagnostic issues that are relevant to the DSM‐5.Research limitations/implicationsBecause of the conceptual or theoretical approach used, the research basis for generalizations is restricted to the practice‐based analyses provided by the authors. Therefore, practitioners and researchers are urged to further test the observations and conclusions presented.Originality/valueThis paper is unique in that it increases the knowledge base related to the diagnostic applications with the DSM‐5, as well as evidence‐based interventions for JFS as it pertains to public safety.
Decomposing variation in male reproductive success: age‐specific variances and covariances through extra‐pair and within‐pair reproduction
Authors: Lebigre Christophe , Arcese Peter , Reid Jane M. 
Published: March 2013

SummaryAge‐specific variances and covariances in reproductive success shape the total variance in lifetime reproductive success (LRS), age‐specific opportunities for selection, and population demographic variance and effective size. Age‐specific (co)variances in reproductive success achieved through different reproductive routes must therefore be quantified to predict population, phenotypic and evolutionary dynamics in age‐structured populations.While numerous studies have quantified age‐specific variation in mean reproductive success, age‐specific variances and covariances in reproductive success, and the contributions of different reproductive routes to these (co)variances, have not been comprehensively quantified in natural populations.We applied ‘additive’ and ‘independent’ methods of variance decomposition to complete data describing apparent (social) and realised (genetic) age‐specific reproductive success across 11 cohorts of socially monogamous but genetically polygynandrous song sparrows (Melospiza melodia). We thereby quantified age‐specific (co)variances in male within‐pair and extra‐pair reproductive success (WPRSandEPRS) and the contributions of these (co)variances to the total variances in age‐specific reproductive success andLRS.‘Additive’ decomposition showed that within‐age and among‐age (co)variances inWPRSacross males aged 2–4 years contributed most to the total variance inLRS. Age‐specific (co)variances inEPRScontributed relatively little. However, extra‐pair reproduction altered age‐specific variances in reproductive success relative to the social mating system, and hence altered the relative contributions of age‐specific reproductive success to the total variance inLRS.‘Independent’ decomposition showed that the (co)variances in age‐specificWPRS,EPRSand total reproductive success, and the resulting opportunities for selection, varied substantially across males that survived to each age. Furthermore, extra‐pair reproduction increased the variance in age‐specific reproductive success relative to the social mating system to a degree that increased across successive age classes.This comprehensive decomposition of the total variances in age‐specific reproductive success andLRSinto age‐specific (co)variances attributable to two reproductive routes showed that within‐age and among‐age covariances contributed substantially to the total variance and that extra‐pair reproduction can alter the (co)variance structure of age‐specific reproductive success. Such covariances and impacts should consequently be integrated into theoretical assessments of demographic and evolutionary processes in age‐structured populations.

SummaryProteostasis is critical for maintaining cell function and proteome stability may play an important role in human embryonic stem cell (hESC) immortality. Notably, hESC populations exhibit a high assembly of active proteasomes, a key node of the proteostasis network. FOXO4, an insulin/IGF‐1 responsive transcription factor, regulates proteasome activity in hESCs. We find that loss of FOXO4 reduces the potential of hESCs to differentiate into neural lineages. Therefore, FOXO4 crosses evolutionary boundaries and links hESC function to invertebrate longevity modulation.

Published: March 2013

ObjectiveThis study examined general medical illnesses and their association with clinical features of bipolar disorder.MethodData were cross‐sectional and derived from the Lithium Treatment – Moderate Dose Use Study (LiTMUS), which randomized symptomatic adults (n = 264 with available medical comorbidity scores) with bipolar disorder to moderate doses of lithium plus optimized treatment (OPT) or to OPT alone. Clinically significant high and low medical comorbidity burden were defined as a Cumulative Illness Rating Scale (CIRS) score ≥4 and <4 respectively.ResultsThe baseline prevalence of significant medical comorbidity was 53% (n = 139). Patients with high medical burden were more likely to present in a major depressive episode (P = .04), meet criteria for obsessive–compulsive disorder (P = .02), and experience a greater number of lifetime mood episodes (P = 0.02). They were also more likely to be prescribed a greater number of psychotropic medications (P = .002). Sixty‐nine per cent of the sample was overweight or obese as defined by body mass index (BMI), with African Americans representing the racial group with the highest proportion of stage II obesity (BMI ≥35; 31%, n = 14).ConclusionThe burden of comorbid medical illnesses was high in this generalizable sample of treatment‐seeking patients and appears associated with worsened course of illness and psychotropic medication patterns.

SummaryThe third interosseous muscle (suspensory ligament,TIOM) is composed of connective tissue (CT) with a variable proportion of muscle (MT) and adipose tissue (AT). The aim of our study is to quantify theCT,MTandATwithin the body and the branches of right thoracic and pelvic limbsTIOMin sound horses to determine whether there are differences inCT,MTandATbetween age, sex, limbs and levels. Right limbs from 11 sound horses were collected. Samples from 6 levels of theTIOMwere embedded in paraffin or in Tissue‐Tek®. Most of the paraffin sections were shredded. Using the cryosection, some artefacts appeared. Cryoprotection was carried out, which produced the best results. Hematoxylin–phloxine–saffron and Hematoxylin–eosin gave a good contrast of colours between the tissues observed allowing the use of an image analysis programme to calculate percentage of each tissue within theTIOM. The percentage ofMTandATdecreased significantly (P < 0.0001), whereas the percentage ofCTincreased significantly (P < 0.0001) with age and when descending from the proximal to the distal level of theTIOM. The percentage ofMTwas significantly higher (P < 0.0001) in females than males, while the percentage ofCTwas significantly higher (P < 0.0001) in males than females. The percentage ofATwas significantly higher (P = 0.0278) in pelvic limbs than in thoracic limbs. These results confirm the variation in tissue composition within theTIOMof sound horses.

AbstractBackgroundNasal polyposis frequently occurs within the clinical picture of aspirin‐exacerbated respiratory disease (AERD).A derailed arachidonic acid metabolism is regarded to be part of the pathophysiology of AERD, and aspirin desensitization is the only causal therapeutic option, so far. The optimal maintenance dose of aspirin desensitization to prevent nasal polyp recurrence on the one hand and to minimize aspirin‐related side‐effects, on the other hand, is still a matter of debate. The aim of this trial was to investigate the efficacy and safety of a low‐dose aspirin desensitization protocol.MethodsAfter sinus surgery, 70 individuals with AERD were randomly allocated to a prospective double‐blind placebo‐controlled aspirin desensitization protocol with a maintenance dose of 100 mg daily. The primary outcome was polyp relapse after 36 months. Nasal endoscopy status, quality of life, and patients' symptom score as well as aspirin‐related side‐effects were monitored.ResultsDue to the high dropout rate, only 31 individuals were evaluated. After 36 months, nasal polyp relapse was less frequent (P = 0.0785) and the polyposis score was lower (P = 0.0702) in the therapy group. Quality of life obviously improved (P = 0.0324), clinical complaints (P = 0.0083) were significantly reduced, and no severe aspirin‐related side‐effects were observed.ConclusionAspirin desensitization with a maintenance dose of 100 mg daily has a positive impact on nasal polyp relapse and seems to be a safe and suitable therapy to improve clinical complaints and the quality of life of individuals with AERD.
