Food Miles, Carbon Footprinting and their potential impact on trade

To obtain market access for NZ food exports to high value developed country markets exporters are having to comply and consider environmental factors such as carbon footprinting. This growth in demand for environmental attributes is shown in the rise of the food miles debate or concept. Food miles is a concept which has gained traction with the popular press arguing that the further food travels the more energy is used and therefore carbons emissions are greater. This paper assesses, using the same methodology, whether this is the case by comparing NZ production shipped to the UK with a UK source. The study found that due to the different production systems even when shipping was accounted for NZ dairy products used half the energy of their UK counterpart and in the case of lamb a quarter of the energy. In the case of apples the NZ source was 10 per cent more energy efficient. In case of onions whilst NZ used slightly more energy in production the energy cost of shipping was less than the cost of storage in the UK making NZ onions more energy efficient overall. The paper then explores other developments in market access to developed markets especially the rise in demand for products to be carbon footprinted and the introduction of carbon labelling. A review of latest methodology in carbon footprinting the PAS from the UK is reviewed and implications for trade assessed.

Is the System Flawed? Legal Ramifications of the Bowl Championship Series and Conference Alignment

Vice Chancellor Williams: Let me start -this is really a discussion, or a panel that deals with the BCS and conference alignment. So why don\u27t we just jump right in it, and I think the first question that I would like to ask is --we\u27ll throw it up, really I think I\u27d like to go to both Mike and Gary on this --why are we seeing all the movement around of the schools from conference to conference? What is this all about? Gary Roberts: That\u27s 95% of it. It is schools trying to reposition themselves better in their industry, which is largely driven by an effort to increase your revenues. Boston College and Miami and Virginia Tech thought they were in a better position, for a variety of reasons, to make more money in the Atlantic Coast Conference; the Atlantic Coast Conference thought it, as a conference --because it could now have a football championship --was certainly strengthened by those schools, so it can make more money. That sort of left the Big East hanging out there to dry, so they went after schools from the next conference down on the food chain, which was our Conference USA, and they picked off Louisville and Cincinnati and South Florida; those schools wanted to go to the Big East because it\u27s a BCS conference and Conference USA isn\u27t --money. So there are some realignments that I think are to some extent driven by --at least in part --some other factors --natural rivalries and what have you. I\u27m still trying to figure out why TCU went to the Mountain West, that\u27s just a total mystery to me. So some of these movements are not explainable solely on the basis of money, but most of them are just a desire to position yourself to increase your revenues

Simulation assisted machine learning

Motivation: In a predictive modeling setting, if sufficient details of the system behavior are known, one can build and use a simulation for making predictions. When sufficient system details are not known, one typically turns to machine learning, which builds a black-box model of the system using a large dataset of input sample features and outputs. We consider a setting which is between these two extremes: some details of the system mechanics are known but not enough for creating simulations that can be used to make high quality predictions. In this context we propose using approximate simulations to build a kernel for use in kernelized machine learning methods, such as support vector machines. The results of multiple simulations (under various uncertainty scenarios) are used to compute similarity measures between every pair of samples: sample pairs are given a high similarity score if they behave similarly under a wide range of simulation parameters. These similarity values, rather than the original high dimensional feature data, are used to build the kernel. Results: We demonstrate and explore the simulation based kernel (SimKern) concept using four synthetic complex systems--three biologically inspired models and one network flow optimization model. We show that, when the number of training samples is small compared to the number of features, the SimKern approach dominates over no-prior-knowledge methods. This approach should be applicable in all disciplines where predictive models are sought and informative yet approximate simulations are available.

Noninvasive temporal detection of early retinal vascular changes during diabetes

Diabetes associated complications, including diabetic retinopathy and loss of vision, are major health concerns. Detecting early retinal vascular changes during diabetes is not well documented, and only few studies have addressed this domain. The purpose of this study was to noninvasively evaluate temporal changes in retinal vasculature at very early stages of diabetes using fundus images from preclinical models of diabetes.Non-diabetic and Akita/+ male mice with different duration of diabetes were subjected to fundus imaging using a Micron III imaging system. The images were obtained from 4 weeks- (onset of diabetes), 8 weeks-, 16 weeks-, and 24 weeks-old male Akita/+ and non-diabetic mice. In total 104 fundus images were subjected to analysis for various feature extractions. A combination of Canny Edge Detector and Angiogenesis Analyzer plug-ins in ImageJ were utilized to quantify various retinal vascular changes in fundus images. Statistical analyses were conducted to determine significant differences in the various extracted features from fundus images of diabetic and non-diabetic animals. Our novel image analysis method led to extraction of over 20 features. These results indicated that some of these features were significantly changed with a short duration of diabetes, and others remained the same but changed after longer duration of diabetes. These patterns likely distinguish acute (protective) and chronic (damaging) associated changes with diabetes. We show that with a combination of various plugging one can extract over 20 features from retinal vasculature fundus images. These features change during diabetes, thus allowing the quantification of quality of retinal vascular architecture as biomarkers for disease progression. In addition, our method was able to identify unique differences among diabetic mice with different duration of diabetes. The ability to noninvasively detect temporal retinal vascular changes during diabetes could lead to identification of specific markers important in the development and progression of diabetes mediated-microvascular changes, evaluation of therapeutic interventions, and eventual reversal of these changes in order to stop or delay disease progression

Delineation of the ancestral tus-dependent replication fork trap

In Escherichia coli, DNA replication termination is orchestrated by two clusters of Ter sites forming a DNA replication fork trap when bound by Tus proteins. The formation of a ‘locked’ Tus– Ter complex is essential for halting incoming DNA replication forks. However, the absence of replication fork arrest at some Ter sites raised questions about their significance. In this study, we examined the genome-wide distribution of Tus and found that only the six innermost Ter sites (TerA–E and G) were significantly bound by Tus. We also found that a single ectopic insertion of TerB in its non-permissive orientation could not be achieved, advocating against a need for ‘back-up’ Ter sites. Finally, examination of the genomes of a variety of Enterobacterales revealed a new replication fork trap architecture mostly found outside the Enterobacteriaceae family. Taken together, our data enabled the delineation of a narrow ancestral Tus-dependent DNA replication fork trap consisting of only two Ter sites

Experience and Outcomes of a Pharmaceutical Care Leadership Residency Program

The University of Minnesota College of Pharmacy’s Ambulatory Care Residency Program has graduated 22 residents from its Leadership Emphasis program from 1999 to 2014. The Leadership Emphasis program is unique in its design, providing a set of experiences over two years focused on developing leadership skills in practice development, establishing personal influence, advocacy in the profession, and teaching. The program’s design has focused on bringing value to three distinct audiences: pharmacists enrolled in the program, the local pharmacy practice community, and the College of Pharmacy. This paper explores the program’s contributions in each of these areas. Program graduates from 1999-2009 were interviewed and cited the independent, yet mentored, activities of the program as instrumental to their professional and personal development. The program has provided significant value to the College of Pharmacy, primarily in the form of instructional support, service to faculty practice sites and development of new practice sites for APPEs. Teaching and precepting hours offset the salary of the residents, resulting in financial benefits for the College. In the second year of the program, residents pursue development of new practice sites, 15 of which have been sustained to provide at least a half-time pharmacist position, having a direct impact on pharmacy practice development in the region. The program provides a win-win-win situation for all the stakeholders involved. Schools and colleges of pharmacy are encouraged to consider whether a similar program may assist in achieving its own goals in practitioner development, teaching and learning, and community engagement

Sociological and Human Developmental Explanations of Crime: Conflict or Consensus

This paper examines multidisciplinary correlates of delinquency in an attempt to integrate sociological and environmental theories of crime with human developmental and biological explanations of crime. Structural equation models are applied to assess links among biological, psychological, and environmental variables collected prospectively from birth through age 17 on a sample of 800 black children at high risk for learning and behavioral disorders. Results show that for both males and females, aggression and disciplinary problems in school during adolescence are the strongest predictors of repeat offense behavior. Whereas school achievement and family income and stability are also significant predictors of delinquency for males, early physical development is the next strongest predictor for females. Results indicate that some effects on delinquency also vary during different ages. It is suggested that behavioral and learning disorders have both sociological and developmental correlates and that adequate educational resources are necessary to ensure channels of legitimate opportunities for high-risk youths

3-D struktura serumske paraoksonaze 1 objašnjava njezinu aktivnost, stabilnost, topljivost i kristalizaciju

Serum paraoxonases (PONs) exhibit a wide range of physiologically important hydrolytic activities, including drug metabolism and detoxification of nerve gases. PON1 and PON3 reside on high-density lipoprotein (HDL) (the “good cholesterol”), and are involved in the alleviation of atherosclerosis. Members of the PON family have been identified not only in mammals and other vertebrates, but also in invertebrates. We earlier described the first crystal structure of a PON family member, a directly-evolved variant of PON1, at 2.2 Å resolution. PON1 is a 6-bladed beta-propeller with a unique active-site lid which is also involved in binding to HDL. The 3-D structure, taken together with directed evolution studies, permitted analysis of mutations which enhanced the stability, solubility and crystallizability of this PON1 variant. The structure permits a detailed description of PON1’s active site and suggests possible mechanisms for its catalytic activity on certain substrates.Serumske paraoksonaze (PONs) imaju široki raspon fiziološki važnih hidrolitičkih aktivnosti uključujući metabolizam lijekova i detoksikaciju nervnih plinova. PON1 i PON3 smještene su na lipoproteinima visoke gustoće (engl. high-density lipoprotein; HDL - “dobri kolesterol”) i uključene su u ublažavanje ateroskleroze. Članovi skupine PON identificirani su ne samo u sisavaca i drugih kralježnjaka već i kod beskralješnjaka. Prije smo opisali prvu kristalnu strukturu člana PON skupine, direktno razrađenu varijantu PON1 pri rezoluciji 2,2 Å. PON1 je beta-propeler sa šest lopatica s jedinstvenim poklopcem aktivnog mjesta, koji je tako|er uključen u vezanje na HDL. 3-D struktura, gledana zajedno s direktnim razvojnim istraživanjima, omogućila je analizu mutacija koje povećavaju stabilnost, topljivost i kristalizaciju te PON1 varijante. Struktura dopušta detaljan opis aktivnog mjesta PON1 i sugerira moguće mehanizme za njezinu katalitičku aktivnost prema odre|enim supstratima

Reductions in circulating levels of IL-16, IL-7 and VEGF-A in myalgic encephalomyelitis/chronic fatigue syndrome

Recently, differences in the levels of various chemokines and cytokines were reported in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) as compared with controls. Moreover, the analyte profile differed between chronic ME/CFS patients of long duration versus patients with disease of less than 3 years. In the current study, we measured the plasma levels of 34 cytokines, chemokines and growth factors in 100 chronic ME/CFS patients of long duration and in 79 gender and age-matched controls. We observed highly significant reductions in the concentration of circulating interleukin (IL)-16, IL-7, and Vascular Endothelial Growth Factor A (VEGF-A) in ME/CFS patients. All three biomarkers were significantly correlated in a multivariate cluster analysis. In addition, we identified significant reductions in the concentrations of fractalkine (CX3CL1) and monokine-induced-by-IFN-γ (MIG; CXCL9) along with increases in the concentrations of eotaxin 2 (CCL24) in ME/CFS patients. Our data recapitulates previous data from another USA ME/CFS cohort in which circulating levels of IL-7 were reduced. Also, a reduced level of VEGF-A was reported previously in sera of patients with Gulf War Illness as well as in cerebral spinal fluid samples from a different cohort of USA ME/CFS patients. To our knowledge, we are the first to test for levels of IL-16 in ME/CFS patients. In combination with previous data, our work suggests that the clustered reduction of IL-7, IL-16 and VEGF-A may have physiological relevance to ME/CFS disease. This profile is ME/CFS-specific since measurement of the same analytes present in chronic infectious and autoimmune liver diseases, where persistent fatigue is also a major symptom, failed to demonstrate the same changes. Further studies of other ME/CFS and overlapping disease cohorts are warranted in future
