A Corrected Plug-in Method for Quantile Interval Construction Through a Transformed Regression

We propose a corrected plug-in method for constructing confidence intervals of the conditional quantiles of an original response variable through a transformed regression with heteroscedastic errors. The interval is easy to compute. Factors affecting the magnitude of the correction are examined analytically through the special case of Box–Cox regression. Monte Carlo simulations show that the new method works well in general and is superior over the commonly used delta method and the quantile regression method. An empirical application is presented.     

A Study of the Relationship Between Innovation and Performance Among NPOs in Pakistan

Abstract

Innovation has become a core driver for the success and survival of organizations regardless of their size and nature. A plethora of literature has discussed the importance of innovation in profit-based organizations, while nonprofit organizations (NPOs) have generally been ignored in research. This study examines the influence of the sub-dimensions of innovation on the performance of NPOs. Data were collected through structured questionnaires using a sample size of 309 NPOs operating in the emerging market Pakistan. The hypotheses were tested through structural equation modeling (SEM) in AMOS.21. The results indicate that process innovation and organization innovation have significant positive influence on the performance of NPOs, while product innovation and marketing innovation have insignificant influence on the performance of NPOs. NPOs are advised to give enough attention to process and organization innovation in order to boost their performance. Future researchers are encouraged to test the model in other environmental settings. Implications for practice were discussed.     

Supply chain relationship quality and its impact on firm performance

Abstract

This paper examines the impact of supply chain relationship quality (SCRQ) on firm performance (FP) through the mediators of supply chain management processes (SCMP) and supply chain performance (SCP). In the literature, these linkages have been examined separately; in contrast, this study takes a holistic perspective on the antecedents of FP. The model was tested using survey data from manufacturing companies. Variance-based structural equation modelling revealed that both SCMP and SCP lead to FP, unlike SCRQ. On the other hand, SCRQ affects SCMP. Drawing on the resource-based view, consistency in SCRQ can lead to not only efficient and effective supply chain management but also improvements in FP and SCP. This research has practical implications, providing supply chain decision makers with insights on enhancing FP. Supply chain decision makers will be able to benefit from the findings of our study by improving supply chain relationships with supply chain members and ensuring FP. This research also highlights how effective management of SCRQ, SCMP and SCP can provide better FP and a competitive advantage.     

Preference and performance linkage in aPhyllocolpa sawfly on the willow,Salix miyabeana, on Hokkaido

A leaf-folding sawfly in the genusPhyllocolpa (Hymenoptera: Tenthredinidae) attackingSalix miyabeana (Salicaceae) was studied near Sapporo, Hokkaido, along the Ishikari River in 1993. Host plant individuals were young trees 4–7 years old which were growing rapidly, producing some long shoots with large leaves. On a gradient of shoot length classes from 0–5 cm long to over 80 cm long, shoots were much more abundant in the shorter shoot length classes. However, attacks by ovipositing females increased as shoot length increase from 0 attacks on the shortest shoots to 5.17 attacks per shoot on the longest shoots. The frequency of attack per leaf increased from 0 to 0.13 over the same range of shoot lengths. This pattern of attack resulted in a high frequency of larval establishment in feeding sites, between 0.96 and 1.00, in all attacked shoot length categories. However, probability of survival to a late instar larva increased with shoot length and corresponded to the attack pattern, indicating a preference-performance linkage between female ovipositional decisions and larval survival. The patterns found for thisPhyllocolpa species are similar for galling sawflies in North America and Europe, especially in the genusEuura, members of which make stem, bud and leaf midrib galls. Extending the pattern to aPhyllocolpa species broadens identification of pattern and ultimately the generality of the emerging theory on populations of galling sawflies.

Feedback-conditional regret theory and testing regret-aversion in risky choice

Regret is an aversive emotion experienced upon the discovery that, had a different choice been made, a higher level of utility would have obtained than actually did. Because regret can be anticipated prior to choice it can lead to regret-minimising decisions. It has been shown that the experience of post-decisional regret is generally dependent on discovering the outcome of foregone acts as well as chosen acts. The most popular version of regret theory does not include an explicit account of the impact of foregone act resolution on anticipated regret-aversion as a decision motive. This restricts its domain of applicability. This paper modifies regret theory to accommodate the impact of outcome feedback on anticipated regret-aversion. The theoretical and empirical implications of this new version of regret theory are discussed.     

Counting family support

Preventative family support approaches are positioned as central to child welfare policy reforms aiming to address the problems of relying upon investigation and out‐of‐home care as the main modes of intervention. Extensive claims are made for family support but relatively little is known about its scope, processes and impact. This study examines the provision of family support in one jurisdiction. A census‐type survey of family support services in one Australian state was conducted using a performance measurement framework in which inputs, outputs, processes and outcomes were measured. Family support services constituted a minor part of child welfare expenditure. They provided a narrow range of service types, and most families received short duration, low intensity services. Workers had difficulty identifying the specific child and family needs that were met by services. For family support to be a genuinely alternative response to concerns about the care of children, it must be capable of making an observable difference in the lives of families experiencing serious difficulties. The collection of aggregate performance data on family support would assist in understanding the nature and outcomes of service provision, as well as ensure family support is ‘counted’ in measurement‐orientated policy and budget processes.     

Using a Consultant Workshop Model to Improve Performance Management in Chinese Autism Agencies: A Preliminary Study

ABSTRACT

This study investigated the outcomes of using a consultant workshop model to help implement performance management (PM) methods in selected Chinese autism agencies. A need for improvement of educational services in Chinese autism agencies was identified. However, the theory and methods of organizational behavior management (OBM) in general and PM in particular are still foreign in the Chinese autism community. The primary research question of the current study was whether first-line teacher performance in Chinese autism agencies could be improved by the use of a consultant workshop model to train management staff to implement a PM system. Four autism agencies in different Chinese provinces participated in this study. Results demonstrated that after the implementation of the PM system through a consultant workshop model in the participating agencies, the performance of first-line teachers in these agencies improved in several important areas. The intervention appeared modestly effective. Implications of the outcome data and future directions for practitioners and researchers are discussed.     

Work Productivity as a Function of the Percentage of Monetary Incentives to Base Pay

In many individual monetary incentive systems workers receive an hourly base pay and can earn incentives when productivity exceeds a specified standard. The total amount that can be earned in incentives is often expressed as a percentage of base pay. This study examined the effects of different percentages of incentive pay to base pay on work productivity. Seventy-five college students were randomly assigned to one of five incentivebase pay conditions: 0% (no incentives), l0%, 30%. 60% or 100%. Subjects participated in 15 forty-five minute sessions during which they assem: bled parts made from bolts, nuts and washers. Subjects received a base pay amount for assembling a minimum of 50 quality parts per session and a per piece incentive for parts over 50. If subjects assernbled 120 quality parts, the production maximum, the total amount they could earn in incentives equaled 0%, l0%, 30%, 60% or 100% of their base pay. Results indicated that the productivity of subjects in the l0%, 30%, 60% and 100% groups was significantly greater than that of subjects in the 0% incentive group; however, the productivity of subjects in the l0%, 30%, 60% and 100% incentive groups did not differ.     

Absenteeism in Health Care: Using Interlocking Behavioral Contingency Feedback to Increase Attendance With Certified Nursing Assistants

This research used an ABA multiple baseline design across hospitals to evaluate a behavioral intervention designed to reduce absenteeism among 64 certified nursing assistants (CNA) in a rural health care organization. Pre-baseline assessments suggested that when CNAs were absent from work, other employees had to work unscheduled shifts. Because of this metacontingency, employees reported that they skipped work themselves to make up for the extra shifts they had to cover. This cycle created more unscheduled shifts and potentially caused the high absenteeism prevalent at the organization. An intervention with normative and metacontingency feedback significantly decreased the total number of days CNAs were absent per week across the three hospitals from a baseline mean of 0.24 (SD?=?0.19) days per week (7.74% of their scheduled hours) to a mean of 0.13 (SD?=?0.17) days per week (3.81% of their scheduled hours) during the intervention. In a return to baseline the total number of days CNAs were absent per week across the three hospitals increased to a mean of 0.24 (SD?=?0.20) days per week (7.47% of their scheduled hours).
