USING CONJOINT ANALYSIS TO PREDICT TRIAL AND REPEAT-PURCHASE PATTERNS OF NEW FREQUENTLY PURCHASED PRODUCTS*

A new approach is proposed to evaluate new-product opportunities. This approach uses the distribution of brand-purchase probability of the new product over a population of potential customers and the outputs from conjoint analysis. The heterogeneous distribution of brand-purchase probability is expressed by a beta binomial brand-choice model compounded with a negative binomial product-class purchase-incidence model. The resulting model provides a way to predict trial and repeat-purchase patterns of new-product concepts. The paper discusses the development of the model. It also discusses issues of measurement, estimation, testing, and implementation of the proposed approach based on actual empirical data.     

The shifting ‘stages’ of performance: a study of ‘Chavang Kut’ festival in Manipur

Chavang Kut, a post-harvesting festival in Manipur, represents an important cultural expression of the Chin-Kuki-Mizo group of people. The article looks at the participation of the Thadou community in the celebration by tracing their performative historiography. In the past, the celebration was primarily important in the religio-cultural sense. The rhythmic movements of the dances in the festival were inspired by animals, agricultural techniques and showed their relationship with ecology. Today, the celebration witnesses the shifting of stages and is revamped to suit new contexts and interpretations. The traditional dances which forms the core of the festival is now performed in the out-of-village settings and are staged in a secular public sphere. While used by the state as a political project to bring unity amongst the different communities of Manipur, recent socio-political occasions showed how it is used as a site of contestations against the state.     

Cognitive skills and leadership performance: The nine critical skills

Over the years, a growing body of evidence indicates that certain cognitive skills are a critical determinant of leader performance. In the present effort we show that application of these skills is typically founded in case-based knowledge. Subsequently, we identify nine key skills people in leadership positions employ when working with case-based knowledge to address leadership problems: 1) problem definition, 2) cause/goal analysis, 3) constraint analysis, 4) planning, 5) forecasting, 6) creative thinking, 7) idea evaluation, 8) wisdom, and 9) sensemaking/visioning. Individual and situational contingencies shaping effective application of these thinking skills is discussed. In addition, the implications of findings bearing on leader thinking skills for leader assessment and leader development are considered.     

Linking Electronic Medical Records Use to Physicians’ Performance: A Contextual Analysis

Electronic Medical Records (EMR) studies have broadly tested EMR use and outcomes, producing mixed and inconclusive results. This study carefully considers the healthcare delivery context and examines relevant mediating variables. We consider key characteristics of: (i) interdependence in healthcare delivery processes, (ii) physician autonomy, and (iii) the trend of hospital employment of physicians, and draw on theoretical perspectives in coordination, shared values, and agency to explain how the use of EMR can improve physicians’ performance. In order to examine the effects of physician employment on work practices in the hospital, we collected 583 data points from 302 hospitals in 47 states in the USA to test two models: one for employed and another for nonemployed physicians. Results show that information sharing and shared values among healthcare delivery professionals fully mediate the relationship between EMR use and physicians’ performance. Next, physician employment determines which mediating variable constitutes the pathway from EMR use to physicians’ performance. Finally, we highlight the impact of shared values between the hospital and physicians in enhancing information sharing and physicians’ performance, extending studies of these behaviors among network partners in industrial settings. Overall, our study shows that EMR use should be complemented by processual (information sharing), social (shared values), and structural (physician employment) mechanisms to yield positive effects on physicians’ performance.     

The efficiency of mutual fund companies: Evidence from an innovative network SBM approach

This paper is the first DEA (Data Envelopment Analysis) evaluation of the efficiency of a sample of mutual fund companies in a large Euro fund industry, i.e. Spain. Our novel network model links the efficiency of the core activities (portfolio management and marketing/distribution) of a mutual fund company to the efficiency of its operational management function. Our results highlight the important networking effects at the marketing stage and question the prime role of portfolio management skills in the overall efficiency of a mutual fund company. The evaluation of robust efficiency clusters indicates that the efficiency rankings obtained with our network model persist significantly along our sample period. Finally, the application of the SBM (Slacks-Based Measure) Variation III to our network model allows us to identify a large number of globally inefficient but locally efficient companies with reference to competitors with similar management resources.     

服务企业绩效差异源泉的理论与实证分析

"服务企业绩效差异的主要源泉是来自行业效应还是企业效应?",通过对2002-2009年中国服务业上市公司的研究,利用方差分析法衡量了行业、企业、年份的主效应以及年份与行业的交互效应对服务企业绩效差异的影响程度。结果显示:(1)服务业有较强的成长能力,可能会有一轮新的资本规模扩张形势;(2)企业效应对服务业上市公司盈利能力起着决定性影响,服务企业要获得可持续超常盈利能力的根本途径,是运用其独特的、无法被模仿的资源来创造可持续的竞争优势,而非多元化进入更有获利能力的产业,更不可能依赖于宏观经济环境的变动;(3)与盈利能力不同,年份效应对服务业上市公司成长能力的影响仅次于企业效应,这种差异性深刻地揭示出投资者的非理性和资本市场亟待完善。     

AD HOC MODEL BUILDING USING TIME-VARYING PARAMETER MODELS*

Decision support for managers and policy makers, such as required in planning and evaluation efforts, often requires ad hoc behavioral modeling to account for context-specific phenomena and to handle data limitations. This paper introduces a systematic approach useful for meeting these requirements in which time-varying parameter estimation plays an important role. A case study evaluating the impacts of public policy actions on residential natural gas conservation illustrates the approach.     

Graphic Feedback,Performance Feedback,and Goal Setting Increased Staff Compliance With a Data Collection Task at a Large Residential Facility

Because of budgetary constraints, human service organizations frequently expect consultants to recommend methods to enhance staff performance that require little or no additional funding. The current study utilized a multiple baseline across settings design to evaluate and compare the effects of a single intervention and a packaged intervention including graphic feedback and goal setting on approximately 200 direct care staff as a group, to improve the data collection procedure at a residential treatment facility. The single intervention showed some improvement, whereas the packaged intervention yielded substantial improvements and was maintained.     

Network learning: Episodes of interorganizational learning towards a collective performance goal

Little is known about learning processes in horizontal networks. This study focuses on networks as learning entities, i.e. learning by multiple organizations as a group, and the mechanisms involved in developing and addressing a network-level performance goal. By using a narrative approach, we gather in-depth primary data from network members to examine: how do firms engage in network learning? and, how is network learning coordinated towards a performance goal in a horizontal inter-firm network? Our findings comprise two learning episodes: ‘learning how to compete’ and ‘learning how to perform’. These episodes help us to understand network learning processes; the relationship between network learning and organizational learning; and the regulatory role a hub firm provides towards a collective performance goal.     

Keeping an Uphill Edge

Abstract

Several behaviors in a ski shop were identified as being deficient using Austin's Performance Diagnostic Checklist (2000) and Daniels and Daniels' PIC/NIC Analysis (2004). During a 4-week baseline, 7 cleaning behaviors were monitored and 5 were subsequently targeted in an intervention package using an ABC design. The intervention included: a task clarification session, a posted behavioral checklist, graphic feedback of the group's performance for the previous week, and daily task-specific feedback. Immediately after the checklist was posted, the frequency of employee cleaning behaviors increased 52%. Cleaning behaviors increased an additional 12% after the implementation of daily task-specific feedback. Results suggest the interventions generalized to the 2 cleaning behaviors not mentioned in the task-clarification session.
