Logistics salience impact on logistics capabilities and performance

Purpose – The purpose of this manuscript is to assess the impact of logistics salience on logistics capabilities and performance. Specifically, the impact of logistics salience on logistics innovativeness and logistics service differentiation is measured along with logistics innovativeness and logistics service differentiation effect on logistics performance. Design/methodology/approach – Conclusions were drawn from survey data gathered from logistics and supply chain managers at US firms. Structural equation modelling was utilized to measure the statistical significance of the hypothesized model paths with all findings meeting the basic requirements of interpretation. Findings – The results suggest that logistics salience positively impacts both logistics innovativeness and logistics service differentiation. Logistics innovativeness and logistics service differentiation both positively influence logistics performance. These findings give credence to the resource based view of the firm which states that resources lead to capabilities which leads to performance. Research limitations/implications – Conclusions based on the study’s results highlight the importance of logistics within firms and indicate that the function must be made salient throughout the firm to further capitalize on the benefits of logistics. These benefits include enhanced logistics capabilities and their eventual impact on logistics performance. Originality/value – Using the resource based view of the firm as the theoretical framework, the manuscript supports the notion that logistics salience is an important resource for firms looking to provide differentiated services and innovative logistics operations to their customers

Enhancing Dyadic Performance Through Boundary Spanners and Innovation: An Assessment of Service Provider–Customer Relationships

Firms recognize that working together through collaborative relationships offers potential benefits such as improving cooperation, information sharing, and overall performance. An additional and extremely valuable benefit of working together is the potential for creating innovative business approaches and solutions. Thus, developing external linkages has become a higher priority within many organizations. Boundary spanning employees offer one means of achieving closer cross‐firm relationships. We investigate the roles of boundary spanners by examining service providers and their relationships with customers. More specifically, we examine boundary spanning employees that are physically on‐site at customer facilities. Results provide strong support that boundary spanners perceiving higher levels of external organizational support from a client subsequently develop affective commitment to the customer. This, in turn, drives knowledge exchange and logistics innovation. A relationship between logistics innovation and performance (of service providers and of customers) was also found. Managerial implications of the research findings are discussed and suggestions presented covering future research

Your community gets a B-: analysis of the specific and curious realm of airport bond rating

Commercial airports are publicly-owned transportation infrastructure, usually funded with bonds. The bond rating decision for these entities thus has important ramifications for bond investors, issuers, airport managers, and even the communities the airports serve, but the rating decision process is not well understood. This paper discusses a simulation of the rating process in two decision environments, including a downgrade. The effect of information framing in an environment of incomplete data is examined using amateur evaluators. Amateur evaluators were utilized to understand how people with limited financial analysis skills would respond when presented with incomplete information and a primed scenario. The results indicate that amateur evaluators were more likely to downgrade a bond grade than a ratings agency, but this effect was moderated for amateur evaluators with more work experience. Implications for airport and supply chain infrastructure are discussed

Urbanness and Its Implications for Logistics Strategy: A Revised Perspective

Due to rapid urbanization, logistics providers are dealing with the conundrum of misaligned strategies for urban environments. Logistics providers often see the urbanness of an activity region as a constraint, while at the same time urban actors view logistics activities within their immediate environment as disruption. These attitudes obscure the value that logistics can provide for urban areas. The current research synchronizes the notions of urban and logistics by reconceptualizing urbanness (i.e., an area’s state of being urban) from the logistics service provider’s perspective. Utilizing a conceptual abstraction technique, the concept of urbanness is revised and differentiated to redefine urban areas as value clusters looking to balance supply and demand globally while also providing access to service at the local urban level. Further, logistics service providers are seen as offering value to urban areas through network logistics and localized logistics. Identifying these differentiated value propositions suggests that transportation providers should respond to urbanness not as a constraint, but as a context where ambidextrous strategies provide the greatest return. Our conceptual revision of urbanness offers promising future avenues of research dealing with urban complexity and logistics providers value appropriation

A Structure–Conduct–Performance Perspective of How Strategic Supply Chain Integration Affects Firm Performance

There are several factors that affect a firm\u27s ability to successfully integrate internally and externally for organizational improvement. This study seeks to understand the relationship between a firm\u27s strategy, its supply chain integration efforts, and firm performance. Leveraging the theoretical lens of structure–conduct–performance from the industrial organization economics literature, and utilizing both archival and survey data, we describe how firms may align their internal and external supply chain integration strategies with customers and suppliers. In doing so, these internal and external integration strategies affect the firm\u27s ability to respond to customer demand, which then impacts operational and financial performance. Our work provides theoretical and empirical evidence of these relationships and thus extends prior strategic supply chain integration literature

Magnetization screening from gluonic currents and scaling law violation in the ratio of magnetic form factors for neutron and proton

The ratio ${\mu_p}G_E^p/G_M^p$ exhibits a decrease for four-momentum transfer Q^2 increasing beyond 1 GeV^2 indicating different spatial distributions for charge and for magnetization inside the proton. One-gluon exchange currents can explain this behaviour. The SU(6) breaking induced by gluonic currents predicts furthermore that the ratio of neutron to proton magnetic form factors ${\mu_p}G_M^n/{\mu_n}G_M^p$ falls with increasing Q^2. We find that the experimental data are consistent with our expectations of an almost linear decrease of the ratio ${\mu_p}G_M^n/{\mu_n}G_M^p$ with increasing Q^2, supporting the statement that the spatial distributions of magnetization are different for protons and for neutrons.Comment: 10 pages, 3 figure

Labor Markets: preventing rivalry and myopia through HRM

Purpose: The purpose of this paper is to extend the concept of myopia and introduce the concept of labor market myopia (LMM), as well as the role that human resources management (HRM) plays in its prevention and resolution. LMM, a more specific form of factor market myopia (FMM), is a myopic view of labor needs. LMM is only going to increase as human capital becomes increasingly scarce due to labor shortages. Design/methodology/approach: This conceptual review focuses on research on factor market rivalry (FMR) in the supply chain. Using three sample job categories, the concept of myopia is applied toward the human resources context to propose a new term describing a failure to consider future labor needs. Findings: The authors position HRM/talent management as critical in preventing and addressing LMM at both firm and industry levels and the critical role of labor markets in FMR. HR strategies are suggested to prevent LMM include: expansion of the available workforce; increasing current workforce productivity, economic remedies like paying higher wages and proactively assessing and forecasting the current and future human resource capacity and needs. Practical implications: Labor needs to be considered as a factor in the same realm of importance as other resources. The HR strategies discussed are key to preventing LMM and improving organizational performance and effectiveness. Originality/value: The authors argue that organizations not only compete for resources downstream (i.e. customers and markets) but also upstream, such as with human resources. The authors introduced a new concept/term to frame the effect on organizations when supply chain planning and HR strategy do not take labor into consideration. This was accomplished by first narrowing the concept of marketing myopia to FMM, and in this conceptual paper, it was subsequently narrowed to introduce the term LMM

Meaning behind measurement : self-comparisons affect responses to health related quality of life questionnaires

Purpose The subjective nature of quality of life is particularly pertinent to the domain of health-related quality of life (HRQOL) research. The extent to which participants’ responses are affected by subjective information and personal reference frames is unknown. This study investigated how an elderly population living with a chronic metabolic bone disorder evaluated self-reported quality of life. Methods Participants (n = 1,331) in a multi-centre randomised controlled trial for the treatment of Paget’s disease completed annual HRQOL questionnaires, including the SF-36, EQ-5D and HAQ. Supplementary questions were added to reveal implicit reference frames used when making HRQOL evaluations. Twenty-one participants (11 male, 10 female, aged 59–91 years) were interviewed retrospectively about their responses to the supplementary questions, using cognitive interviewing techniques and semi-structured topic guides. Results The interviews revealed that participants used complex and interconnected reference frames to promote response shift when making quality of life evaluations. The choice of reference frame often reflected external factors unrelated to individual health. Many participants also stated that they were unclear whether to report general or disease-related HRQOL. Conclusions It is important, especially in clinical trials, to provide instructions clarifying whether ‘quality of life’ refers to disease-related HRQOL. Information on selfcomparison reference frames is necessary for the interpretation of responses to questions about HRQOL.The Chief Scientist Office of the Scottish Government Health Directorates, The PRISM funding bodies (the Arthritis Research Campaign, the National Association for the Relief of Paget’s disease and the Alliance for Better Bone Health)Peer reviewedAuthor final versio

Investigating the missing data mechanism in quality of life outcomes: a comparison of approaches

Background: Missing data is classified as missing completely at random (MCAR), missing at random (MAR) or missing not at random (MNAR). Knowing the mechanism is useful in identifying the most appropriate analysis. The first aim was to compare different methods for identifying this missing data mechanism to determine if they gave consistent conclusions. Secondly, to investigate whether the reminder-response data can be utilised to help identify the missing data mechanism. Methods: Five clinical trial datasets that employed a reminder system at follow-up were used. Some quality of life questionnaires were initially missing, but later recovered through reminders. Four methods of determining the missing data mechanism were applied. Two response data scenarios were considered. Firstly, immediate data only; secondly, all observed responses (including reminder-response). Results: In three of five trials the hypothesis tests found evidence against the MCAR assumption. Logistic regression suggested MAR, but was able to use the reminder-collected data to highlight potential MNAR data in two trials. Conclusion: The four methods were consistent in determining the missingness mechanism. One hypothesis test was preferred as it is applicable with intermittent missingness. Some inconsistencies between the two data scenarios were found. Ignoring the reminder data could potentially give a distorted view of the missingness mechanism. Utilising reminder data allowed the possibility of MNAR to be considered.The Chief Scientist Office of the Scottish Government Health Directorate. Research Training Fellowship (CZF/1/31

The Abdominal Circulatory Pump

Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs) is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50–75 ml with an ejection fraction of 4–6% and an output of 750–1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61±0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57±0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC) and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart
