The impact of collaborative engagement on knowledge and performance gains in episodic collaborations
Authors: W. Nix Nancy , G. Zacharia Zach 
Published: July 2014

Purpose– Supply chains are embedded in a larger network of enterprises where firms exchange offerings, often compete for the same customers, and constantly innovate to improve their performance. In these dynamic environments, firms are increasingly dependent on the knowledge and expertise in external organizations to innovate, problem-solve, and improve performance. Firms are increasingly collaborating to exchange and pool skills and knowledge and deploy resources and capabilities not found in their own firm. This research using both structured interviews and survey data seeks to determine what are the direct benefits and the ancillary benefits of collaboration. The paper aims to discuss these issues.Design/methodology/approach– A mixed methodology approach was utilized, using qualitative structured interviews leading to developing a research model and then an empirical survey of 473 participants who are involved in their respective organization's collaboration projects. The data were analyzed using structural equation modeling to examine relationships between collaborative engagement, knowledge gained, operational outcomes and relational outcomes.Findings– The results of the study indicate that collaborative engagement has a direct effect on knowledge gained, operational outcomes and relational outcomes in collaboration. The ancillary benefit of collaboration is the learning that takes place leads to improved operational outcomes and relational outcomes.Research limitations/implications– In this research study all the constructs are only examined from a single perspective. This can be a limitation as it would be of greater value to collect data from all the members involved in the collaboration.Originality/value– Collaboration has been well studied in many fields but this research suggests an important ancillary benefit that needs to be considered when deciding to collaborate is the knowledge and learning that happens during a collaboration.
A reverse logistics inventory model for plastic bottles
Authors: Matar Nouri , Y. Jaber Mohamad , Searcy Cory 
Published: July 2014

Purpose
– The purpose of this paper is to present an original model for the production-recycling-reuse of plastic beverage bottles.

Design/methodology/approach
– It is assumed that discarded two-liter plastic polyethylene terephthalate (PET) bottles are collected from the market. The bottles are then sorted into non-contaminated and contaminated streams. The non-contaminated PET bottles are either remanufactured or used as regrind mixed with virgin PET to produce new bottles to satisfy varying demand. The contaminated bottles are either sold to industries using low-grade plastic or disposed of in a landfill. Numerical studies are used to illustrate the behaviour of the model, with an emphasis on exploring the reduction of total system cost and the amount of bottles going into a landfill.

Findings
– Numerical analyses conducted on the model found that the amount of bottles collected had the largest influence on the outcome of the total system unit time cost. Alternative materials to PET are surveyed and used to demonstrate a significant reduction in the cost of landfill disposal due to their more rapid degradation in the landfill.

Research limitations/implications
– Several areas for future work are highlighted. Potential modifications to the model could focus on accommodating bottles made of material other than plastic, incorporating the effects of learning on manual tasks, and on accommodating shortages or excess inventory.

Originality/value
– The model incorporates several unique aspects, including accounting for the cost of land use and associated environmental damage through the calculation of a present value that is charged to the manufacturer.
Correlates of customer loyalty to financial institutions: a case study
Authors: Yavas Ugur , Babakus Emin , D. Deitz George , Jha Subhash 
Published: July 2014

Purpose
– The purpose of this study is to investigate the relative efficacies of intrinsic and extrinsic cues as drivers of customer loyalty to financial institutions between male and female bank customers.

Design/methodology/approach
– A large-scale survey of 872 customers of a national bank serves as the study setting.

Findings
– Results showed that extrinsic cues were the more effective correlates of customer loyalty and that gender does not moderate the relationships between image cues and customer loyalty.

Research limitations/implications
– The cross-sectional nature of the current study does not allow causal inferences. Therefore, future studies should adopt longitudinal designs.

Practical implications
– Results suggest that, although transmitting a favorable image through extrinsic cues is critical, nevertheless, intrinsic cues (interactions among customers and bank personnel) should not be ignored. To reinforce this not only among current customers but also among potential customers, banks should use advertisements featuring favorable testimonials.

Originality/value
– Empirical research in the banking services literature pertaining to the efficacies of intrinsic and extrinsic cues in forming customer loyalty is scarce. This study fills in the void. Also, in determining if the relationships between image and customer loyalty vary by gender, the authors not only looked at male versus female differences on the basis of average construct scores but also examined the structural relationships among the constructs.
Functional assessment of mycosporine‐like amino acids in Microcystis aeruginosa strain PCC 7806

Published: July 2014

SummaryThe biological role of the widespread mycosporine‐like amino acids (MAAs) in cyanobacteria is under debate. Here, we have constructed and characterized two mutants impaired in MAA biosynthesis in the bloom‐forming cyanobacterium Microcystis aeruginosa PCC 7806. We could identify shinorine as the sole MAA type of the strain, which is exclusively located in the extracellular matrix. Bioinformatic studies as wells as polymerase chain reaction screening revealed that the ability to produce MAAs is sporadically distributed within the genus. Growth experiments and reactive oxygen species quantification with wild‐type and mutant strains did not support a role of shinorine in protection against UV or other stress conditions in M. aeruginosa PCC 7806. The shinorine content per dry weight of cells as well as transcription of the mys gene cluster was not significantly elevated in response to UV‐A, UV‐B or any other stress condition tested. Remarkably, both mutants exhibited pronounced morphological changes compared with the wild type. We observed an increased accumulation and an enhanced hydrophobicity of the extracellular matrix. Our study suggests that MAAs in Microcystis play a negligible role in protection against UV radiation but might be a strain‐specific trait involved in extracellular matrix formation and cell–cell interaction.
An Investigation of Red Fox (Vulpes vulpes) and Eurasian Badger (Meles meles) Scavenging, Scattering, and Removal of Deer Remains: Forensic Implications and Applications

Published: July 2014

AbstractWithin northwest Europe, especially the United Kingdom, the red fox (Vulpes vulpes) and the Eurasian Badger (Meles meles) are the largest wild scavengers capable of modifying a set of remains through scavenging. Knowledge of region‐specific and species‐typical scavenging behaviors of scavengers within the crime scene area and surroundings can aid in more efficient and accurate interpretations. The scavenging behaviors of captive and wild foxes and badgers were recorded and compared through actualistic methods and direct observation. The scavenging by wild foxes and badgers of surface‐deposited baits and whole deer (Cervus nippon; Capreolus capreolus) in a woodland was observed and analyzed. Wild foxes were found to scavenge deer more frequently than badgers. The scavenging of deer remains by foxes was also compared with forensic cases. The scavenging pattern and recovery distances of deer and human remains scavenged by foxes were similar but were potentially affected by the condition and deposition of a body, and the presence of clothing.
The Analysis of a World War I U.S. Service Member's Dental Remains Recovered in France
Authors: Shiroma Calvin Y. 
Published: July 2014

AbstractIn October 2009, the grave of an unknown World War I (WWI) U.S. service member was exhumed in Rembercourt‐Sur‐Mad Village, in the Lorraine Region of France. The skeletal remains and material evidence were accessioned into the Joint POW/MIA Accounting Command's (JPAC) Central Identification Laboratory (CIL). The personnel records for the associated casualty were requested, received, and reviewed. A dental profile was present among the service member's personal information. There were multiple points of concordance between the dental records of the associated casualty, and the recovered dental remains to include eight restored teeth, 15 unrestored teeth, and three antemortem missing teeth. Distinctive restorations which compared favorably included a porcelain crown and multiple gold foil fillings. All lines of evidence (historical, material evidence/personal effects, anthropological, and dental) and the circumstances of loss compared positively with the associated casualty. On April 1, 2010, the previously unaccounted‐for U.S. service member was positively identified and on June 23, 2010, was buried with full military honors at Arlington National Cemetery.
Surface Modification for the Collection and Identification of Fingerprints and Colorimetric Detection of Urea Nitrate
Authors: Cross Shoronia N. , Quinteros Elliot , Roberts Marcel 
Published: July 2014

AbstractGlass surfaces were modified with a combination of dyes and reagents to allow for the potential simultaneous recording of a detailed fingerprint and the detection of the explosive urea nitrate (UN), as a proof of principle of surface modification for simultaneous linking of identity to manipulation of explosives. By coating microscope slides with 9,10‐diphenylanthracene (DPA), p‐dimethylaminobenzaldehyde (p‐DMAB) and p‐dimethylaminocinnamaldehyde (p‐DMAC), a colorimetric change was observed in the presence of UN, while revealing a fingerprint with enough resolution to isolate at least 10 minutiae. This is the first step in creating point‐of‐care devices capable of detecting low concentrations of explosives and drug metabolites and connecting them to a fingerprint.
Establishing Tobacco Origin from Pollen Identification: An Approach to Resolving the Debate
Authors: Williams Shane , Hubbard Shelby , Reinhard Karl J. , Chaves Sergio Miranda 
Published: July 2014

AbstractPrevious research into pollen content of tobacco resulted in a debate. We address this debate and determine that pollen analysis may be able to assist with identifying geographical origin of tobacco. However, the value of any results should be assessed on a case‐by‐case regional basis until sufficient database information is available for an objective interpretation to be undertaken on a global basis. As a first step toward developing comparative data for South America, we analyzed a tobacco sample from Brazil in an effort to identify signature taxa from the state of Minas Gerais. We also assessed the role of honey additives to tobacco to assess this issue. Comparing the data to previously published data, we conclude that pollen signatures can distinguish broad geographic areas. We conclude that this forensic interpretation framework needs to be developed in context of the National Academy of Sciences recommendations for tightening methods in forensic science.
Mid‐level providers and emergency care: Let's not lose the force
Authors: Tintinalli Judith E 
Published: July 2014

AbstractThe progressive rise of ED visits globally, and insufficient numbers of emergency physicians, has resulted in the use of mid‐level providers as adjuncts for the provision of emergency care, especially in the US and Canada. Military medics, midwives, aeromedical paramedics, EMT‐Ps, flight nurses, forensic nurses, sexual assault nurse examiner nurses ‐ are some examples of well‐established mid‐level provider professionals who achieve their clinical credentials through accredited training programmes and formal certification. In emergency medicine, however, mid‐level providers are trained for general care, and typically acquire emergency medicine skills through on‐the‐job experience. There are very few training programmes for NPs and PAs in emergency care. The manpower gap for physicians in general, and emergency physicians specifically, will not be eliminated in the reasonable future. Mid‐level providers – ENTs, paramedics, NPs, PAs – are an excellent addition to the emergency medicine workforce. However, the specialty of emergency medicine developed because specific and focused training was needed for physicians to practice safe and qualify emergency care. This same principle applies to mid‐level providers. Emergency Medicine needs to develop a vision and a plan to train emergency medicine specialist NPs and PAs, and explore other innovations to expand our emergency care workforce.
Review article: Maxillofacial emergencies: Oral pain and odontogenic infections
Authors: DeAngelis Adrian F , Barrowman Roland A , Harrod Richard , Nastri Alf L 
Published: July 2014

AbstractOral pain and odontogenic infections are common reasons for patients to present to EDs and general medical practice in Australia. Although most odontogenic infections can be managed on an outpatient basis, because of their proximity to the airway, infections in this region can be life threatening, requiring urgent surgical intervention and ICU management. This article focuses on the emergency assessment, triage and non‐specialist management of oral pain and odontogenic infections.
Suburban Toxicity: A Political Ecology of Asbestos in Australian Cities
Authors: HOUSTON DONNA , RUMING KRISTIAN 
Published: July 2014

AbstractThis paper explores the toxic legacy of asbestos in Australian suburbs and cities. During the post‐war period, Australia had one of the highest per capita rates of asbestos use in the developed world. As a consequence of this indiscriminate use, Australia also has one of the highest rates of asbestos dust disease in the world. Drawing on feminist approaches to urban political ecology (UPE) and the materialities of waste, we trace the entanglement of asbestos within the everyday spaces of homes and suburbs and through urban governance structures and processes of urban regeneration. We argue that UPE provides an important framework for putting asbestos stories and practices in the city together. UPE highlights the relational entanglements and injustices of asbestos, which render it as matter that circulates through bodies, homes, infrastructures, working‐class histories and suburban imaginaries. This approach challenges the construction of asbestos in terms of its hazardous obsolescence and resituates it as complex matter that continues to be lived with and practiced.

AbstractBackgroundThe aim of the present study was to assess the role of a concomitant type 2 diabetes as a potentially negative factor in the management of low‐risk myelodysplastic syndrome (MDS) patients treated with high‐dose (40 000 UI s.c. 2 times/week) recombinant human erythropoietin (EPO) alpha (rHuEPO alpha).MethodsOne hundred and forty patients (M/F 69/71, median age 76, interquartile range [IR] 68–81) were included in the analysis: 27/140 (19.2%) had a concomitant type 2 diabetes.ResultsNo difference was reported between patients with and without diabetes as to the grade of anemia, the EPO endogenous levels and the need for transfusional requirement at baseline. Erythroid response was achieved in 79/140 patients (56.4%): factors associated with response were lower EPO levels (P < 0.0001), higher baseline Hb levels (P < 0.0001) and transfusion independence (P < 0.0001). Diabetes was not predictive of response: 17/27 (62.9%) patients with diabetes were responsive to high‐dose EPO compared with 62/113 (54.8%) patients without diabetes (P = 0.446). This was confirmed in multivariate analysis, controlling for the effects of Hb levels, transfusion‐dependence and serum EPO levels. No difference was observed in relapse rate, response duration and OS between patients with and without diabetes.ConclusionsConcomitant type 2 diabetes was not a major concern in the management of MDS patients.

AbstractBackgroundThe aim of this study was to investigate the early onset effects of diabetes on pro‐angiogenic signaling pathway, total number of bone marrow cells, organs (pancreas and kidney) damage and the reversal effect of diabetes by combinatorial treatment of curcumin and bone marrow transplantation in streptozotocin (STZ) induced diabetic mice.MethodsIn the present study, Streptozotocin induced diabetic mice were transplanted with bone marrow cells (2 × 106) followed by the administration of curcumin (80 mg/kg bodyweight). Effect of diabetes on the different organs was studied by H&E, Western blotting and immunofluorescence using vascular endothelial growth factor (VEGF), platelet/endothelial cell adhesion molecule (PECAM), insulin, Caspase‐9 and Caspase‐3 antibodies.ResultsThe effect of diabetes results in the reduction of the total cell number and viability of the bone marrow cells, organ degeneration and lower VEGF/PECAM expression. However, transplantation with normal bone marrow cells significantly reduced the blood glucose levels (above normal range) and initiated the organ regeneration via the VEGF/PECAM mediated manner. Curcumin treatment further reduced the blood glucose level (near normal); and accelerated the organ regeneration, enhanced VEGF/PECAM expression and decreased caspase expression level in the organs. Curcumin also had a protective role against the glucotoxicity test performed on the bone marrow cells.ConclusionThis study suggests that bone marrow transplantation and curcumin administration is an effective treatment in reversing the early onset effects of diabetes via the VEGF/PECAM signaling pathway.
Phylogenetic exploration of commonly used medicinal plants in South Africa
Authors: Yessoufou Kowiyou , Daru Barnabas H. , Muasya Abraham Muthama 
Published: July 2014

AbstractThe rapid growth rate of human population, along with the public health crisis encountered in many regions, particularly in developing world, creates an urgent need for the discovery of alternative drugs. Because medicinal plants are not distributed randomly across lineages, it has been suggested that phylogeny along with traditional knowledge of plant uses can guide the identification of new medicinally useful plants. In this study, we combined different statistical approaches to test for phylogenetic signal in 33 categories of plant uses in South Africa. Depending on the null models considered, we found evidence for signal in up to 45% of plant use categories, indicating the need for multiple tests combination to maximize the chance of discovering new medicinal plants when applying a phylogenetic comparative approach. Furthermore, although there was no signal in the diversity of medicinal uses—that is, total number of medicinal uses recorded for each plant—our results indicate that taxa that are evolutionarily closely related have significantly more uses than those that are evolutionarily isolated. Our study therefore provides additional support to the body of the literature that advocates for the inclusion of phylogeny in bioscreening medicinal flora for the discovery of alternative medicines.
A systematic review and meta‐analysis of ketamine for the prevention of persistent post‐surgical pain
Authors: MCNICOL E. D. , SCHUMANN R. , HAROUTOUNIAN S. 
Published: July 2014

While post‐operative pain routinely resolves, persistent post‐surgical pain (PPSP) is common in certain surgeries; it causes disability, lowers quality of life and has economic consequences. The objectives of this systematic review and meta‐analysis were to evaluate the effectiveness of ketamine in reducing the prevalence and severity of PPSP and to assess safety associated with its use.We searched the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE through December 2012 for articles in any language. We included randomized, controlled trials in adults in which ketamine was administered perioperatively via any route.Seventeen studies, the majority of which administered ketamine intravenously, met all inclusion criteria. The overall risk of developing PPSP was not significantly reduced at any time point in the ketamine group vs. placebo, nor did comparisons of pain severity scores reach statistical significance. Sensitivity analysis of exclusively intravenous ketamine studies included in this meta‐analysis demonstrated statistically significant reductions in risk of developing PPSP at 3 and 6 months (P = 0.01 and P = 0.04, respectively). Adverse event rates were similar between ketamine and placebo groups.The study data from our review are heterogeneous and demonstrate efficacy of intravenously administered ketamine only in comparison with placebo. Highly variable timing and dosing of ketamine in these studies suggest that no unifying effective regimen has emerged. Future research should focus on clinically relevant outcomes, should stratify patients with pre‐existing pain and possible central sensitization and should enroll sufficiently large numbers to account for loss to follow‐up in long‐term studies.
