Third party social sustainability assessment: Is it a multi-tier supply chain solution?

The paper examines the different third party approaches used to assess the social sustainability of global multi-tier supply chains. Information asymmetries between supply chain actors and stakeholders can result in uncertainty about how a good has been produced and traded, resulting in sustainability uncertainty. Third party social sustainability assessment is one mechanism used to monitor and communicate the credentials of everyday products to stakeholders. We frame our study using information processing theory to discuss how third party assessors can help to reduce sustainability uncertainty. As social sustainability is of particular importance in labor-intensive industries, empirical data is drawn from agriculture, textiles, handicrafts, footwear and consumer electronics supply chains. The analysis of semi-structured interviews with assessors reveals differing approaches to assessment. We show how these approaches utilize differing numbers of supply chain tiers. Some, for example, focus only on the farmer or raw material supplier when assessing social sustainability, which raises questions about the credentials of actors further downstream. The communities and livelihoods of supply chain actors, often located in the global South, can be dependent on the new, niche and potentially more profitable markets made available to goods that can demonstrate their social sustainability credentials. Robust assessment is therefore integral in accessing these new markets. The study offers a comparison between different assessors that will be of interest to scholars and also to supply chain actors considering engaging in social sustainability assessment

Using organisational theories to further our understanding of socially sustainable supply chains

Purpose – This paper aims to use organisational theories to frame research questions examining how to embed social sustainability in supply chain management (SCM) by focusing on fair trade. Design/methodology/approach – Drawing on previous organisational theory review papers in SCM, institutional theory and the extended resource-based view have been used as theoretical lenses to develop research questions for further studies. Findings – The authors developed seven research questions that enable and encourage the further examination of the factors impacting fair trade supply chains, as well as identify approaches to improve social sustainability in SCM practice. Social implications – As the aim of fair trade is to rebalance inequities inherent in North–South trading relationships, further work in this area has the potential for positive economic, environmental and social impact. Originality/value – The paper discusses two key themes: whether fair trade is changing SCM practices, and whether fair trade is a source of competitive advantage in supply chains. Using established theory to develop research questions encourages further examination of this important topic

Missing Attention to Power Dynamics in Collaborative Multi-Actor Business Models for Sustainability

Advances within the Sustainability Business Models (SBMs) literature from the perspective of boundary-spanning business models have received limited attention. Further, discourse within the SBMs literature exploring collaborative practices adopts the perspective that collaborative forums are always a ‘force for good’. This paper reviews important theories and relevant literature and calls into question the dearth of research examining business models for sustainability and focuses on the role that power, and power relations, play in the shaping and steering of value creation. In advancing research on sustainable operations, we assess the implications of ignoring uneven power, and draw attention to the affects and consequences of this omission in the study of SBMs. By embracing an alternative, deliberative democracy perspective, we challenge the sub-literature on collaborative multi-actor business models. In taking an inquisitive and critical stance on omnipresent power dynamics, we shine a light on the consequences of uneven power across multi-actor structures by augmenting research with practical insights from selected vignettes. Our proposed concept of a democratic business model for sustainability offers a new strand of theoretical development and a fresh perspective on the sustainability and business models literature

Sports operations management: examining the relationship between environmental uncertainty and quality management orientation

Research question: The outcome of a sporting competition is uncertain and one of the key reasons for the sustained popularity of spectator sport. Whilst unique and exciting, this context poses challenges for the management of the sporting experience as there is no control over the outcome of the competition; a disappointing result on-field may translate to a disappointing overall experience for the spectators. We wish to understand if and how quality management practices can be used in off-field operations to mitigate on-field uncertainty, and thus have greater control over spectator perception of the sporting experience. Research methods: A multi-country survey of operations managers of sporting stadia in the United Kingdom, United States, Canada, Australia and New Zealand was conducted. We operationalize environmental uncertainty as spectator co-creation and enforced collaboration, and assess quality management orientation from both a customer and process perspective. Linear regression is used for data analysis. Results and Findings: Surprisingly, we find that environmental uncertainty does not encourage the orientation of quality management practices towards the customer. Instead, we find a greater application of process focus. In considering sporting fans as passive customers rather than active co-creators of value, quality management practices seem to have skewed towards process rather than person. Implications: Customer satisfaction appears as secondary to process performance in the sample of stadia examined. This is in contrast to studies that have encouraged a focus on the customer in contexts of environmental uncertainty. We suggest a renewed focus on the customer for the longevity of sporting stadia

Pituitary Adenylate Cyclase-Activating Polypeptide Stimulates Glucose Production via the Hepatic Sympathetic Innervation in Rats

OBJECTIVE-The unraveling of the elaborate brain networks that control glucose metabolism presents one of the current challenges in diabetes research. Within the central nervous system, the hypothalamus is regarded as the key brain area to regulate energy homeostasis. The aim of the present study was to investigate the hypothalamic mechanism involved in the hyperglycemic effects of the neuropeptide pituitary adenylyl cyclase-activating polypeptide (PACAP). RESEARCH DESIGN AND METHODS-Endogenous glucose production (EGP) was determined during intracerebroventricular infusions of PACAP-38, vasoactive intestinal peptide (VIP), or their receptor agonists. The specificity of their receptors was examined by coinfusions of receptor antagonists. The possible neuronal pathway involved was investigated by 1) local injections in hypothalamic nuclei, 2) retrograde neuronal tracing from the thoracic spinal cord to hypothalamic preautonomic neurons together with Fos immunoreactivity, and 3) specific hepatic sympathetic or parasympathetic denervation to block the autonomic neuronal input to liver. LTS-Intracerebroventiicular infusion of PACAP-38 increased EGP to a similar extent as a VIP/PACAP-2 (VPAC2) receptor agonist, and intracerebroventricular administration of VIP had significantly less influence on EGP. The PACAP-38 induced increase of EGP was significantly suppressed by preinfusion of a VPAC2 but not a PAC1 receptor antagonist, as well as by hepatic sympathetic but not parasympathetic denervation. In the hypothalamus, Fos immunoreactivity induced by PACAP-38 was colocalized within autonomic neurons in paraventricular nuclei projecting to preganglionic sympathetic neurons in the spinal cord. Local infusion of PACAP-38 directly into the PVN induced a significant increase of EGP. CONCLUSIONS-This study demonstrates that PACAP-38 signaling via sympathetic preautonomic neurons located in the paraventricular nucleus is an important component in the hypothalamic control of hepatic glucose production.

Output from VIP cells of the mammalian central clock regulates daily physiological rhythms

The suprachiasmatic nucleus (SCN) circadian clock is critical for optimising daily cycles in mammalian physiology and behaviour. The roles of the various SCN cell types in communicating timing information to downstream physiological systems remain incompletely understood, however. In particular, while vasoactive intestinal polypeptide (VIP) signalling is essential for SCN function and whole animal circadian rhythmicity, the specific contributions of VIP cell output to physiological control remains uncertain. Here we reveal a key role for SCN VIP cells in central clock output. Using multielectrode recording and optogenetic manipulations, we show that VIP neurons provide coordinated daily waves of GABAergic input to target cells across the paraventricular hypothalamus and ventral thalamus, supressing their activity during the mid to late day. Using chemogenetic manipulation, we further demonstrate specific roles for this circuitry in the daily control of heart rate and corticosterone secretion, collectively establishing SCN VIP cells as influential regulators of physiological timing

Alternative Splicing of sept9a and sept9b in Zebrafish Produces Multiple mRNA Transcripts Expressed Throughout Development

Background: Septins are involved in a number of cellular processes including cytokinesis and organization of the cytoskeleton. Alterations in human septin-9 (SEPT9) levels have been linked to multiple cancers, whereas mutations in SEPT9 cause the episodic neuropathy, hereditary neuralgic amyotrophy (HNA). Despite its important function in human health, the in vivo role of SEPT9 is unknown. Methodology/Principal Findings: Here we utilize zebrafish to study the role of SEPT9 in early development. We show that zebrafish possess two genes, sept9a and sept9b that, like humans, express multiple transcripts. Knockdown or overexpression of sept9a transcripts results in specific developmental alterations including circulation defects and aberrant epidermal development. Conclusions/Significance: Our work demonstrates that sept9 plays an important role in zebrafish development, an
