Abstract:This study explores the conceptual investigational foundations of how two existing concepts of supply chain exploitative practices and supply chain explorative practices together may further inform the balanced theory of port competitiveness (BTOPC). The defined and validated factors of the BTOPC are further investigated via the lens offered by ambidextrous supply chain strategy, which is defined and measured through the simultaneous practice of exploitative and explorative activities. The exploratory nature of this study aims to help academics to further the theory of port competitiveness and assist practitioners in improving port management. Eight in-person interviews with practitioner and academic port experts were conducted in addition to follow-up telephone conversations. This study finds that supply chain exploitative and explorative practices indeed offer a unique vantage view for assessing the port competitiveness when utilizing the BTOPC factors.

Abstract:The container shipping industry has undergone a substantial structural alteration recently, the main cause of which stems from the enlargement of ship sizes. Previous research on the topic lacked the discussion of the impact of an upsizing policy on the inner operation and management of carriers. Through cognition agreement and decision importance, this study investigated 32 factors that may affect industrial experts whose companies own or order mega containerships. The results of this investigation reveal that cash-flow control, increasing profits, increasing feeders to collect cargo, and gaining competitive advantage are the most determinant factors that affect decision making. European carriers are more concerned than Asian carriers about the potential safety risks in navigation and the trend of persistently ordering megaships. Asian carriers recognize the decreased agility of megaship deployment but strongly dissent from European carriers.

Abstract:As Brazilian soybean exports doubled between 2001/02 and 2011/12 and major production areas consolidated in remote inland Cerrado regions, moving product to port has proven to be a challenge. A review of the literature, data analysis, and interviews with experts in the logistics chain revealed that a lack of grain storage, overreliance on trucking, poor road conditions, and inefficient operations at rail terminals and ports impede a smooth flow of grain from farm to port. Because of the comparatively low per-unit values of agricultural bulk commodities, transportation may account for a large share of the total cost of soybean exports. As a result, it was hypothesized that increases in transportation costs may reduce farm-gate prices, affecting producer profitability and, thus, national production. To test that hypothesis, this study examined transportation costs from inland production regions to traffic hubs and the Santos seaport. A comparison of theoretical producer prices calculated based on logistics costs versus actual local prices was employed to confirm that transport inefficiencies have led to depressed farm gate prices.

Frontotemporal degeneration (FTD) and amyotrophic lateral sclerosis (ALS), once considered separate neurodegenerative disorders, are now recognized to have many commonalities at the molecular, cellular, and clinical level. Behavioral and language symptoms characteristic of FTD can appear concurrently or over time in persons diagnosed with ALS; similarly, symptoms of motor neuron disease can occur in persons diagnosed with FTD. In addition, the hallmark pathological feature in both disorders is the aggregation of the RNA-binding protein TDP-43, while a hexanucleotide repeat expansion in C9orf72 is the most common genetic mutation in hereditary FTD, ALS, and FTD-ALS (also known as FTD-MND). As a result, experts have proposed that these disorders constitute a clinical spectrum, with some patients exhibiting primarily ALS symptoms, some exhibiting primarily FTD symptoms, and still others with overlapping symptom profiles. This intersection of FTD and ALS is a compelling argument for prioritizing the development of diagnostic tools and therapeutics applicable to both disorders to facilitate the alignment of clinical care practices as well as drug and biomarker development.

Abstract:Accidents involving large commercial trucks kill over 3,000 motorists every year in the United States. A substantial number of these accidents stem from truck drivers operating their trucks while excessively fatigued. This concern has resulted in regulatory agencies establishing hours-of-service (HOS) rules that carriers must ensure their drivers abide by. In this study we examine the relationship between carriers’ capability at monitoring their truck drivers using electronic technologies and carrier-level compliance with HOS rules. Drawing on principles from deterrence theory, we explain why this relationship should be sigmoidal (S-shaped) in nature such that motor carriers receive the greatest gains from investing in electronic monitoring capability when they have a moderate level of this capability. We subject our theorized prediction to empirical testing using a longitudinal research design that combines primary data on motor carriers’ electronic monitoring capability and secondary data from regulators regarding carrier-level compliance with HOS rules. Results from our econometric analysis corroborate the hypothesized sigmoidal relationship, which stands up to stringent robustness testing. These results hold important implications for theory and practice.

Abstract:This article scrutinizes the link between supplier leveraging and product innovation performance with the contingency of intellectual capital. Supplier leveraging refers to the utilization of knowledge obtained from suppliers for the benefit of the firm and product innovation performance to the firm’s ability to introduce new and radically different products. Intellectual capital is represented by the trichotomy of structural, human, and social capital. Applying the knowledge-based view, a positive moderation effect emanating from structural and human capital is hypothesized, with however a negative moderation effect emanating from social capital. The expectation for the positive moderation is grounded in the enabling knowledge processing capabilities of structural and human capital, enhancing the effectiveness of supplier leveraging for the generation of product innovation performance. The negative moderation of social capital is suggested due to it likely limiting the transferability and aggregation capacity for knowledge, in addition to also potentially questioning the legitimacy of the suppliers’ information, and thus making knowledge leveraged from suppliers less effective in informing product innovation performance. Data collected from 576 manufacturing firms confirm these hypotheses. Overall, by considering the interplay between supplier leveraging and intellectual capital, and its effect on product innovation performance, this study offers important new insight on the dynamics governing product innovations within supply chains.

Abstract:City express delivery demand is characterized by large quantities, small parcel sizes, dense batch frequency, and timeliness. To meet demand and control costs and CO2 emissions from parcel delivery, a collaborative delivery mode using bus vehicles and a truck fleet is proposed. A model is built to optimize delivery schemes based on a bus–road mixed network and thus minimize the fixed cost, the delivery cost, the compensation cost for the emitted CO2, and the unpunctuality penalty cost. An ant-colony algorithm is designed to solve the model. Delivery schemes for the 97 demand sites in a Chinese city are calculated under collaborative mode and truck-only mode. The advantages of a collaborative mode are verified by comparing the two types of delivery schemes.

Abstract:In the years following an initial public offering (IPO), firms have to manage portfolios of customers and suppliers in order to achieve growth goals during this particularly uncertain time in a firm’s lifecycle. The current research sheds light on three key questions: (1) Do firms benefit from conducting a large portion of business with a large customer or supplier? (2) Is it beneficial if the focal firm represents a large portion of business for customers and suppliers? And, (3) is balanced portfolio dependence helpful to a focal firm? The extant literature, drawing insights from the logics of power and embeddedness, is divided on these questions. We utilize a secondary data set of focal firms (post-IPO) and their portfolios of relationships with customers and suppliers to explain where each theoretical perspective applies to the management of supply chain portfolios.
