Exploring the Effect of Supplier Management on Performance in the Korean Automotive Supply Chain
Authors: Park Seungwook , Hartley Janet L. 
Published: April 2006

SUMMARYThis article explores the relationship between supply management practices and performance from a supply chain perspective. A conceptual model of suppliermanagement practices and performance was developed and tested using covariance structural modeling. Survey data were gathered from first‐tier suppliers in the Korean automotive industry. The results showed that in a supply chain, the suppliermanagement practices adopted by first‐tier suppliers affected second‐tier suppliers' performance. Second‐tier suppliers' performance consequently influenced both first‐tier suppliers' quality and delivery performance. These findings suggest that best practices in supplier management should be transferred upstream in the supply chain to improve overall performance of the entire supply chain.
Enhancing Supply Decisions through the Use of Efficient Marginal Costs Models
Authors: Talluri Srinivas 
Published: April 2006

SUMMARYSupply managers are often faced with the challenge of making effective purchasing decisions in acquiring production materials, supplies, and capital equipment. The complexity of the procurement process has mainly intensified due to the increased emphasis on delivery performance, product quality, and technical service apart from traditional cost measures This article presents a set of multi‐criteria models for estimation of efficient marginal costs of supplier outputs, which provide critical information to managers on the values of outputs. The marginal costs are utllized for making effective purchasing decisions by setting optimal output prices for negotiation on supplier bids. The models are tested on an actual dataset of suppliers.
A Multi‐Criteria Group Decisionmaking Model for Supplier Rating
Authors: Muralidharan C. , Anantharaman N. , Deshmukh S.G. 
Published: April 2006

SUMMARYAn important problem in decision analysis is the evaluation of the difference between two or more different rankings for a set of alternatives. A novel model based on the aggregation technique for combining group member's preferences into one consensus ranking is suggested in this article. The model developed may be used to develop consensus and evolve ranking of alternatives. The application of the model is demonstrated through a case for supplier rating. The advantages of the proposed approach are also highlighted.
What is SCM? And, Where is It?
Authors: Larson Paul D. , Halldorsson Arni 
Published: April 2006

SUMMARYThis article provides insight on the evolution and emergence of the supply chain management(SCM) concept and shares conclusions about the future of SCM from the perspective of educators, researchers, and practitioners. Based on a survey of SCM educators, the article seeks to delimit the scope or domain of SCM and how the boundaries have changed and continue to change. This is done by contrasting four perspectives on SCM versus purchasing: traditionalist, relabeling, unionist, and intersectionist.

Creating Corporate Advantage through Purchasing: Toward a Contingency Model
Authors: Rozemeijer Frank A. , van Weele Arjan , Weggeman Mathieu 
Published: April 2006

SUMMARYThis study was undertaken to address the need for empirical research for improving and sustaining corporate advantage through purchasing. This article explains how large corporations may effectively manage purchasing synergies among individual business units. It will become clear that in doing so, corporate purchasing officers (CPOs) need to tailor their approach depending on three constructs, i.e., purchasing maturity, corporate coherence, and business context. Based upon these constructs, they may select five different coordinating mechanisms to foster purchasing synergies within their corporation.

The Impact of Cycle Time on Supplier Selection and Subsequent Performance Outcomes
Authors: Sharland Alex , Eltantawy Reham A. , Giunipero Larry C. 
Published: April 2006

SUMMARYCycle time is among the emerging performance criteria for purchasing and supply management. However, little empirical research has been conducted for actually evaluating the impact of cycle time on strategic issues, such as long‐term business relationships and supplier selection and evaluation processes. This study empirically tests the impact of cycle time on supplier selection and on the effectiveness of long‐term relationships with suppliers, as reflected in the commitment and trust developed. Findings indicate that initial cycle time is not a significant predictor of trust and commitment in the context of supplier‐buyer long‐term relationships. However, cycle time reduction along with consistently high quality were found to be significant predictors of trust and commitment in long‐term relationships.
An Agency Theory Investigation of Supply Risk M anagement
Authors: Zsidisin George A. , Ellram Lisa M. 
Published: April 2006

SUMMARYManaging supply risk is an essential element of the overall supply management task. As the complexity of risk management has increased, responsiveness seems dominated by varying the level of inventory and using multiple supply sources as means of creating buffers. This research uses the framework of agency theory in managing supplier behaviors as a means to reduce supply risk and the impact of detrimental events. Empirical results indicate that purchasing organizations address various sources of supply risk by implementing management techniques that reduce the likelihood that detrimental events will occur. Firm size, purchases as a percentage of sales, and industry characteristics were also found to influence the manner in which supplier behaviors are managed.
Deciding on the Mode of Negotiation: To Auction or Not to Auction Electronically
Authors: Kaufmann Lutz , Carter Craig R. 
Published: April 2006

SUMMARYPurchasing transactions are increasingly conducted through electronic auctions. Some companies already source 25 percent of their total purchase volume through this electronic mechanism. However, most of these purchasing transactions could, alternatively, be conducted as face‐to‐face negotiations. This article examines (a) when it is feasible to conduct an electronic auction in purchasing, and (b) under what circumstances it is better to source items through an electronic auction as opposed to sourcing them through face‐to‐face negotiations.
The Use of Organizational Design Features in Purchasing and Supply Management
Authors: Trent Robert J. 
Published: April 2006

SUMMARYThis article presents findings from a study examining organizational design features used by organizations in pursuing their procurement and supply objectives. The research purpose was to gain a better understanding of the organizational design features that firms currently use or may use in the future. The results should encourage organizations to address design issues as they relate to overall supply management effectiveness. Given the dynamics of the current competitive global supply landscape, organizational design concerns are critical to sustained organizational success.
Gender Issues in Buyer‐Seller Relationships: Does Gender Matter in Purchasing?
Authors: Pullins Ellen Bolman , Reid David A. , Plank Richard E. 
Published: April 2006

SUMMARYWhile differences between male and female salespeople are well documented in the literature, evidence is less clear whether these differences matter to the buyer or whether buyers of different gender make decisions differently. The article reports results of a survey of male and female purchasers on the behaviors, trust, credibility and customer orientation of a salesperson. Almost no differences were found on any of the variables for male or female buyers. This calls into question past research that has found differences, and this paper argues that previous findings, while statistically significant, are probably not managerially significant.
Understanding and Managing the Services Supply Chain
Authors: Ellram Lisa M. , Tate Wendy L. , Billington Corey 
Published: April 2006

SUMMARYServices have become increasingly important as the driving force in the U.S. economy. However, there has been little research to date on services supply chains. It is believed that service businesses can benefit by applying some best practices from manufacturing to their processes. However, the inherent differences in services create a need for supply chain management tools specific to the services sector. This article documents the growing importance of the services sector and of services purchasing. Next, it develops a supply chain framework appropriate for a services supply chain by comparing and contrasting the applicability of three product‐based manufacturing models: Global Supply Chain Forum Framework, SCOR and Hewlett‐Packard's Supply Chain Management Model. Finally, this research describes the challenges for procurement professionals managing purchases for a services supply chain and provides suggestions for use of supply chain management theory, and practices for improvement.
Firm and Individual Choice Drivers in Make‐or‐Buy Decisions: A Diminishing Role for Transaction Cost Economics?
Authors: McNally Regina C. , Griffin Abbie 
Published: April 2006

SUMMARYTransaction cost economics (TCE) is an empirically supported, theoretical paradigm that has been used to understand and predict the outcomes of make‐or‐buy decisions. At the same time, TCE research has been criticized for focusing solely on firm‐level economic determinants of decision outcomes without considering other factors that may impact decision making in organizations. The purpose of this research is to examine the effects of variables associated with TCE and compensation systems on the outcomes of make‐or‐buy decisions to compare the predictive ability of these variables in the current business environment. Findings indicate that functional group reward systems are associated with the outcomes of make‐or‐buy decisions. Surprisingly, no support is found for the association between the TCE variables and decision outcomes.
Evaluating the Performance of Third‐Party Logistics Arrangements: A Relationship Marketing Perspective
Authors: Knemeyer A. Michael , Murphy Paul R. 
Published: April 2006

SUMMARYBy 2005, users of third‐party logistics services may be spending an average of nearly one‐third of their total logistics budgets (compared to 20 percent today) to support 3PL services (Gooley 2000). Yet, very little research has examined managerial activities that might influence the performance of these logistics outsourcing relationships. Over the past several years, the management approach that views relationships as key assets of the organization has gained increased prominence in the priorities and practices of many companies (Gruen, Summers and Acito 2000). The current study utilizes this relationship marketing perspective as the basis for evaluating the perceived performance of third‐party logistics arrangements. In particular, the current study examines the influence of six key relationship marketing dimensions on a customer's perceptions of their 3PL provider's performance. In so doing, the article builds on research (e.g., Goldsby and Stank 2000) that focuses on potential linkages between logistical performance metrics and managerial activities. The results suggest linkages between relationship marketing activities and the perceived performance of the 3PL arrangement.

AbstractAim:  To determine the roles of myostatin and insulin‐like growth factor‐I (IGF‐I) during postnatal growth, we examined IGF‐I and myostatin mRNA expression in the skeletal muscles of hypophysectomized and underfed rats during postnatal growth.Methods:  Five‐week‐old rats were divided into four groups: freely fed control, moderately underfed, severely underfed and hypophysectomized. Four weeks later, blood and muscle samples were gathered to determine serum IGF‐I, myosin heavy chain (MHC) isoforms, IGF‐I Ea, IGF‐I Eb and myostatin mRNA.Results:  The weights of soleus, plantaris and masseter muscles were decreased in underfed and hypophysectomized rats. Hypophysectomy resulted in significant increases of type I MHC at the expense of type IIx in plantaris muscle and of neonatal MHC at the expense of types IIx and IIb in masseter muscle. Serum IGF‐I was decreased by underfeeding and hypophysectomy. Plantaris muscle IGF‐I Ea mRNA in underfed and hypophysectomized rats was significantly lower than in normal controls. Plantaris muscle IGF‐I Eb mRNA in underfed rats was significantly lower than in normal controls. Masseter muscle IGF‐I Eb mRNA in severely underfed rats was significantly lower than in normal control and hypophysectomized rats. Soleus muscle myostatin mRNA in hypophysectomized rats was significantly higher than in normal and significantly underfed rats. No significant differences in plantaris and masseter muscle myostatin mRNA were observed between groups.Conclusion:  Suppressed muscle growth caused by hypophysectomy and underfeeding may be attributed mainly to reduced circulating IGF‐I and partially to reduced IGF‐I mRNA, rather than to a change in myostatin.
Does central nitric oxide chronically modulate the acute hypoxic ventilatory response in conscious rats?
Authors: Schwenke D. O. , Pearson J. T. , Kangawa K. , Shirai M. 
Published: April 2006

AbstractAim:  Hypoxia initiates an increase in ventilation (VE) through a cascade of events of which central nitric oxide (NO) has been implicated as an important neuromodulator. There have not been any reports describing the consequences of long‐term imbalances in the central NO pathways on the modulation of the acute hypoxic ventilatory response (HVR). Chronic hypoxia (CH) can potentially modify the HVR, and so we hypothesized that central NO may be involved. In this study we describe the long‐term role of central NO in the modulation of HVR before and after CH.Methods:  Male Sprague–Dawley rats (BW c. 200–320 g; n = 21) were implanted with an osmotic pump for continuous intracerebroventricular administration of either artificial cerebrospinal fluid (control), Nω‐nitro‐l‐arginine methyl ester (l‐NAME) (150 μg kg−1 day−1) or the NO‐donor, 3‐[4‐morpholinyl]‐sydnonimine‐hydrochloride (SIN‐1) (100 μg kg−1 day−1). The VE response to acute poikilocapnic hypoxia (8% O2 for 20 min) was measured by plethysmography seven days after surgery, in normoxia, and again after 14 days of exposure to CH (CH = 12% O2).Results:  The magnitude of the HVR (c. 230% increase in VE) was unaltered by centrally infusing either l‐NAME or SIN‐1 for 1 week. CH did not modify the HVR, although baseline VE and HVR were shifted downward by l‐NAME during CH – because of a reduction in the frequency component.Conclusions:  These results suggest that long‐term alterations in central NO levels may not alter the HVR under moderate CH, presumably because of the onset/development of compensatory mechanisms. However, NO appears to be an important component of the HVR following CH.
Approximating fixed points of total asymptotically nonexpansive mappings

Published: April 2006

AbstractWe introduce a new class of asymptotically nonexpansive mappings and study approximating methods for finding their fixed points. We deal with the Krasnosel'skii-Mann-type iterative process. The strong and weak convergence results for self-mappings in normed spaces are presented. We also consider the asymptotically weakly contractive mappings.

Published: April 2006

AbstractSuppose "Equation missing" is a nonempty closed convex subset of a real Banach space "Equation missing". Let "Equation missing" be two asymptotically quasi-nonexpansive maps with sequences "Equation missing" such that "Equation missing" and "Equation missing", and "Equation missing". Suppose "Equation missing" is generated iteratively by "Equation missing" where "Equation missing" and "Equation missing" are real sequences in "Equation missing". It is proved that (a) "Equation missing" converges strongly to some "Equation missing" if and only if "Equation missing"; (b) if "Equation missing" is uniformly convex and if either "Equation missing" or "Equation missing" is compact, then "Equation missing" converges strongly to some "Equation missing". Furthermore, if "Equation missing" is uniformly convex, either "Equation missing" or "Equation missing" is compact and "Equation missing" is generated by "Equation missing", where "Equation missing", "Equation missing" are bounded, "Equation missing" are real sequences in "Equation missing" such that "Equation missing" and "Equation missing", "Equation missing" are summable; it is established that the sequence "Equation missing" (with error member terms) converges strongly to some "Equation missing".
Common fixed point and invariant approximation results in certain metrizable topological vector spaces
Authors: Hussain Nawab , Berinde Vasile 
Published: April 2006

AbstractWe obtain common fixed point results for generalized "Equation missing"-nonexpansive "Equation missing"-subweakly commuting maps on nonstarshaped domain. As applications, we establish noncommutative versions of various best approximation results for this class of maps in certain metrizable topological vector spaces.

Authors: Benevieri Pierluigi , Calamai Alessandro , Furi Massimo 
Published: April 2006

AbstractIn a recent paper we gave a notion of degree for a class of perturbations of nonlinear Fredholm maps of index zero between real infinite dimensional Banach spaces. Our purpose here is to extend that notion in order to include the degree introduced by Nussbaum for local "Equation missing"-condensing perturbations of the identity, as well as the degree for locally compact perturbations of Fredholm maps of index zero recently defined by the first and third authors.
Fixed points and controllability in delay systems
Authors: Gao Hang , Zhang Bo 
Published: April 2006

AbstractSchaefer's fixed point theorem is used to study the controllability in an infinite delay system "Equation missing". A compact map or homotopy is constructed enabling us to show that if there is an a priori bound on all possible solutions of the companion control system "Equation missing", then there exists a solution for "Equation missing". The a priori bound is established by means of a Liapunov functional or applying an integral inequality. Applications to integral control systems are given to illustrate the approach.

The anosov theorem for infranilmanifolds with an odd-order abelian holonomy group
Authors: Dekimpe K , De Rock B , Pouseele H 
Published: April 2006

AbstractWe prove that "Equation missing" for any continuous map "Equation missing" of a given infranilmanifold with Abelian holonomy group of odd order. This theorem is the analogue of a theorem of Anosov for continuous maps on nilmanifolds. We will also show that although their fundamental groups are solvable, the infranilmanifolds we consider are in general not solvmanifolds, and hence they cannot be treated using the techniques developed for solvmanifolds.
Autoreactive MZ and B-1 B-cell activation by Faslpr is coincident with an increased frequency of apoptotic lymphocytes and a defect in macrophage clearance

Published: April 2006

AbstractMurine autoreactive anti-Smith (Sm) B cells are negatively regulated by anergy and developmental arrest, but are also positively selected into the marginal zone (MZ) and B-1 B-cell populations. Despite positive selection, anti-Sm production occurs only in autoimmune-prone mice. To investigate autoreactive B-cell activation, an anti-Sm transgene was combined with the lpr mutation, a mutation of the proapoptotic gene Fas (Faslpr), on both autoimmune (MRL) and nonautoimmune backgrounds. Faslpr induces a progressive and autoantigen-specific loss of anti-Sm MZ and B-1 B cells in young adult Faslpr and MRL/Faslpr mice that does not require that Faslpr be B-cell intrinsic. This loss is accompanied by a bypass of the early pre–plasma cell (PC) tolerance checkpoint. Although the MRL bkg does not lead to a progressive loss of anti-Sm MZ or B-1 B cells, it induces a robust bypass of the early pre-PC tolerance checkpoint. Faslpr mice have a high frequency of apoptotic lymphocytes in secondary lymphoid tissues and a macrophage defect in apoptotic cell phagocytosis. Since Sm is exposed on the surface of apoptotic cells, we propose that anti-Sm MZ and B-1 B-cell activation is the result of a Faslpr-induced defect in apoptotic cell clearance.
