Associations between parenting styles and nutrition knowledge and 2–5-year-old children's fruit, vegetable and non-core food consumption
Authors: Peters Jacqueline , Dollman James , Petkov John , Parletta Natalie 
Published: October 2012

AbstractObjectiveDuring the early years, parents have a major influence on children's diets and developing food choices. We investigated parenting styles as predictors of 2–5-year-old children's diets and whether general nutrition knowledge (GNK) mediated these influences.DesignCross-sectional research. Questionnaires measured demographic and lifestyle variables, family environment, parenting styles and feeding practices, child diet and GNK. Regression models tested GNK as a mediator of relationships between parenting variables and child diet (fruit/vegetable and non-core food consumption), controlling for confounders and family environment.SettingQuestionnaires were completed by main caregivers at home.SubjectsParents of children aged 2–5 years (n269).ResultsHigher child fruit/vegetable consumption was associated with lower over-reactive parenting and restriction, higher authoritative parenting and dining together as a family; with lax parenting approaching statistical significance (P= 0·083) and 19 % of variance explained by the model. GNK was not a significant predictor. Conversely, non-core food consumption was associated with higher over-reactive and lax parenting as well as child age, increased takeaway food consumption and higher television viewing; GNK had a small effect (P= 0·043) and 28 % of variance was explained by the model. GNK was a significant mediator only for authoritative parenting on non-core food (effect = −0·005).ConclusionsThese findings highlight that young children's diets may be improved by interventions targeting a range of positive and supportive parenting practices in conjunction with nutrition knowledge education for parents of young children. Further insights will come from closer attention to the nature and role of restrictive feeding practicesv. laxness and longitudinal research.
Property, possession and natural resource management: towards a conceptual clarification
Authors: HOFFMANN SABINE 
Published: October 2012

Abstract:There are few concepts that are more central to natural resource management than those of property and property rights. Given their importance, it might be expected that there would be some consensus in the economic literature about what property and property rightsare. However, no such consensus seems to exist. In fact, different authors use the same terms to denote quite disparate concepts and ideas, impeding rather than advancing progress in understanding natural resource management. As but one example, there is hardly a concept that has been as fundamentally misunderstood as that of the commons. That misunderstanding notwithstanding, there is another, less familiar, more common and even more fundamental one: the persistent confusion of possession with property. This article argues that the distinction between possession and property is of particular importance for comprehending the meaning of institutional shifts from one resource management regime to another. It therefore reviews concepts central to natural resource management, by distinguishing between state, private, common property and possession on the one hand and open access on the other.
Citizen, interrupted: the 2011 English riots from a psychosocial perspective
Authors: Aiello G. , Pariante C. M. 
Published: October 2012

Aims.This is a contribution to the debate over the 2011 English riots from a psychosocial perspective.Methods.We compare the impulsive and ‘mindless’ behaviour of rioters with the impulsive, violent and contradictory behaviour of people affected by severe personality disorders.Results.We propose that the lack of a sense of social identity and of mentalization skills is a common feature of the two conditions – the lack of social identity, leading to frustration and anger, coupled with a lack of mentalization, leading to the impulsive and violent expression. Furthermore, we highlight the confusing impact that the social marginalization and consumerism can have on young generations from lower classes in cities from the Western world.Conclusions.By building a parallel with the therapeutic intervention offered to severe personality disorders, we speculate on how the community, by modifying its communication's style and actively intervene in deprived socio-economic contexts, could inspire more confidence, trust and sense of belonging in its marginalized members.
Coverage of mental health and substance misuse topics in the Cochrane review system
Authors: Green-Hennessy S. 
Published: October 2012

Aims.To assess the breadth of mental and substance coverage in the Cochrane review system.Methods.All mental health and substance entries were identified from the 2005 to April 2012 Cochrane Database of Systematic Reviews.Results.A total of 1019 entries focused on mental health or substance misuse, with 698 (68.5%) being completed reviews. One out of every five entries focused on serious mental illness/psychosis. Systematic reviews addressing unipolar depression, dementia and certain substance disorders also appeared well-represented. In contrast, a number of impairing disorders frequently seen in practice received less attention, with bipolar disorder, obsessive compulsive disorder (OCD), post-traumatic stress disorder (PTSD) and autism spectrum disorders each accounting for less than 2% of the entries. The majority of interventions reviewed involved medication (57.1%), although this was not the case for a number of childhood-onset disorders. Some diagnostic areas (sleep, anxiety, mood and substance) were addressed by multiple Cochrane review groups (CRGs).Conclusions.The Cochrane Collaboration is well poised to be a strong guiding influence to those seeking to employ evidence-based mental health care. Broadening its diagnostic coverage and diversifying types of intervention reviewed would probably further maximize its impact. A more centralized and directed approach of prioritizing topics could help ensure more comprehensive coverage.

Published: October 2012

AS160 (Akt substrate of 160 kDa) is a Rab GTPase-activating protein implicated in insulin control of GLUT4 (glucose transporter 4) trafficking. In humans, a truncation mutation (R363X) in one allele of AS160 decreased the expression of the protein and caused severe postprandial hyperinsulinaemia during puberty. To complement the limited studies possible in humans, we generated an AS160-knockout mouse. In wild-type mice, AS160 expression is relatively high in adipose tissue and soleus muscle, low in EDL (extensor digitorum longus) muscle and detectable in liver only after enrichment. Despite having lower blood glucose levels under both fasted and random-fed conditions, the AS160-knockout mice exhibited insulin resistance in both muscle and liver in a euglycaemic clamp study. Consistent with this paradoxical phenotype, basal glucose uptake was higher in AS160-knockout primary adipocytes and normal in isolated soleus muscle, but their insulin-stimulated glucose uptake and overall GLUT4 levels were markedly decreased. In contrast, insulin-stimulated glucose uptake and GLUT4 levels were normal in EDL muscle. The liver also contributes to the AS160-knockout phenotype via hepatic insulin resistance, elevated hepatic expression of phosphoenolpyruvate carboxykinase isoforms and pyruvate intolerance, which are indicative of increased gluconeogenesis. Overall, as well as its catalytic function, AS160 influences expression of other proteins, and its loss deregulates basal and insulin-regulated glucose homoeostasis, not only in tissues that normally express AS160, but also by influencing liver function.
An Analysis of Malar Fat Volume in Two Age Groups: Implications for Craniofacial Surgery
Authors: Corey Christina L. , Popelka Gerald R. , Barrera Jose E. , Most Sam P. 
Published: October 2012

Objective To evaluate how malar fat pad (MFP) volumes vary with age, after controlling for gender and body mass index (BMI). Study Design A prospective case–control study evaluating volume of the MFP in women of two age groups. Methods Soft tissue dimensions were measured in eight subjects using magnetic resonance imaging. A multiplanar localizing sequence, followed in sagittal and coronal orientations using a turbo spin echo sequence, was performed to define the MFP. Volumetric calculations were then performed using a 3D image analysis application (Dextroscope, Volume Interactions, Republic of Singapore) to circumscribe areas, orient dimensions, and calculate volumes of the MFP. Results These data reveal no significant difference in the mean (standard deviation) right MFP ( p = 0.50), left MFP ( p = 0.41), or total MFP ( p = 0.45) volumes when comparing the two age groups. In addition, these data indicate that there was no correlation between age and total MFP volume (Pearson correlation coefficient 0.27). Moreover, there was no correlation between age and the ratio of total volume/BMI (Pearson correlation coefficient −0.18). Conclusions Although the sample size of this study was small, these data indicate that ptosis of midfacial fat is more important than volume loss in midfacial aging. These data would suggest repositioning as the primary modality for craniofacial reconstruction.
Near-coincident K-line and K-edge energies as ionization diagnostics for some high atomic number plasmas

For some high atomic number atoms, the energy of the K-edge is tens of eVs higher than the K-line energy of another atom, so that a few eV increase in the line's energy results in a decreasing transmission of the x-ray through a filter of the matching material. The transmission of cold iridium's ≃63.287 keV Kα2 line through a lutetium filter is 7% lower when emitted by ionized iridium, consistent with an energy increase of Δε≃10±1 eV associated with the ionization. Likewise, the transmission of the Kβ1 line of ytterbium through a near-coincident K-edge filter changes depending on plasma parameters that should affect the ionization. Systematic exploration of filter-line pairs like these could become a unique tool for diagnostics of suitable high energy density plasmas.

First Report of Bacterial Spot Caused by Xanthomonas campestris pv. vesicatoria on Sweet Pepper (Capsicum annuum L.) in Saudi Arabia
Authors: Ibrahim Y. , Al-Saleh M. 
Published: October 2012

In the summer of 2009 and 2010, 18 sweet pepper fruit with blister-like, raised, rough lesions were collected from four greenhouses (total of 0.1 ha) in the Al-Kharj region of Saudi Arabia. All samples were collected from commercial crops of the sweet pepper cv. California Wonder. Disease incidence was ≤5%. Isolations were made from all diseased fruits. A small piece (3 mm2) of symptomatic tissue from pepper fruit was placed in a sterile mortar and macerated in sterile distilled water with a pestle. A loopful of bacterial suspension from each sample was streaked onto Tween B agar medium (3). Plates were incubated at 28°C for 48 h. Single yellow, circular, butyrous, shiny colonies were picked from the plates and transferred to nutrient agar plates containing 5% D+ glucose agar (NGA). Gram-negative, rod-shaped bacteria were consistently isolated from the fruit and 10 of the isolates were identified as Xanthomonas campestris pv. vesicatoria on the basis of morphological, physiological, and biochemical tests (1,2). The isolates were oxidase positive and levan negative, arginine-dihydrolase positive, and did not macerate potato discs. The isolates were also non-fluorescent, grew at 37 and 4°C but not at 40°C, did not liquefy gelatine or starch, but did produce H2S. The identity of the 10 bacterial strains was confirmed by PCR assay using primers RST65 and RST69 (4). Four-week old pepper plants (cv. California Wonder) were inoculated by spraying five potted plants with each isolate using a bacterial suspension (108 CFU/ml). Sterile distilled water was sprayed on an additional five plants as a negative control treatment. The bacterial isolates caused necrotic lesions, each with a yellow halo, on leaves of inoculated plants. Bacteria reisolated from the necrotic lesions using the technique previously described were identical to the original strains according to the morphological, cultural, and biochemical tests described above. Negative control plants inoculated with sterile distilled water did not show symptoms and no bacterial colonies were recovered from them. To our knowledge, this is the first report of bacterial spot on pepper fruits in Saudi Arabia. References: (2) R. F. Bradbury. Genus II Xanthomonas Dowson 1939.

Effects of agricultural policy reforms and farm characteristics on income risk in Swiss agriculture
Authors: El Benni Nadja , Finger Robert , Mann Stefan 
Published: October 2012

PurposeThe purpose of this study is to examine the effects of agricultural policy reform – specifically the change from market to direct payment support – on income variability of Swiss farming households. In addition, the observed heterogeneity in income risks across farms and time is explained in terms of farm and regional characteristics.Design/methodology/approachUnbalanced farm‐level panel data of the Swiss farm accountancy network (FADN) are used to construct coefficients of variation of five‐year overlapping time intervals for total household income and gross farm revenues over the period 1992 to 2009. Linear fixed effect models are applied to measure the effect of specialization, off‐farm income, direct payments, farm size, and liquidity on the variability of gross farm revenues and household income in the valley, hill, and mountain regions.FindingsThe switch from market‐based support to direct payments has decreased the variability of farm revenues and household income. The strong reliance on direct payments serves as insurance for most farmers and reduces both household income and revenue risk. Off‐farm income can be used by farmers to reduce household income risk but it increases revenue risk in the valley regions. In all of the regions considered, farm size has a positive effect on household income risk and a negative effect on revenue risk. A high degree of specialization increases both gross revenue and household income risk. Potential revenue insurance contracts should specify farmers' off‐farm employment, the degree of specialization, farm size, and regional specific risk profiles.Originality/valueThis paper assesses the complementary effects of specific farm characteristics and risk management strategies with regard to both farm revenue and household income risk. Influences of agricultural policy changes on income risks are also empirically assessed at different spatial scales.
The role of an agribusiness index in a modern portfolio
Authors: Clark Benjamin M. , Detre Joshua D. , D'Antoni Jeremy , Zapata Hector 
Published: October 2012

PurposeThe purpose of this research is to develop a composite agribusiness stock index and then compare the returns and volatility to other broad‐based market indices. The paper then evaluates the diversification potential of agribusiness stocks in the context of an investment portfolio.Design/methodology/approachThis agribusiness index (AGB Index) is market‐capitalization weighted. Only firms traded on the NYSE, AMEX, or NASDAQ and meeting ERS SIC classification for industries related to agriculture are included in the index. The paper then uses standard financial metrics to measure the historical risk, return, and correlation.FindingsUntil recent years, the AGB Index has historically exhibited lower returns than the market indices. The AGB Index has also exhibited lower risk and correlation with treasury securities than broad market indices.Practical implicationsIn recent years, portfolio managers and large investors have invested considerably in asset classes like farmland for stable returns, an inflation hedge, and diversification tool. This agribusiness index may further this trend and lead to the development of an alternative Exchange Traded Fund (ETF). This product would make investment in agriculture possible for virtually all investors.Originality/valueDespite increasing popularity, very little research exists on the performance of agricultural stocks in an investment portfolio. This study develops a large‐cap agribusiness stock price index to help fill this void in the literature.
Effects of crop acreage and aggregation level on price‐yield correlations
Authors: Finger Robert 
Published: October 2012

PurposeThe purpose of this paper is to analyze the effects of data aggregation and farm‐level crop acreage on the level of natural hedge, i.e. the level of price‐yield correlations, which is an important issue in risk modeling and management.Design/methodology/approachSwiss FADN data for five crops covering the period 2002‐2009 are used to estimate price‐yield correlations at the farm‐ as well as on an aggregated level. Tobit regressions are used to estimate empirical relationships between the level of natural hedge and the underlying crop acreage.FindingsPrice‐yield correlations differ significantly between farm‐ and aggregated‐level. More specifically, the natural hedge observed at the farm‐level is much smaller, i.e. correlations are closer to zero. Taking correlations from aggregated levels thus leads to an underestimation of farm‐level revenue variability. Furthermore, it is found that larger farms have a stronger natural hedge. For instance, a 1 percent increase in area under maize and intensive barley leads to a change in the correlation by −0.02 and −0.08, respectively.Practical implicationsThe natural hedge is often approximated with correlations observed at more aggregated levels, e.g. the county level. The results show that this implies errors in risk assessment and modeling as well as insurance applications. Thus, farm‐level estimates should be used. The here presented relationship between price‐yield correlations and farm‐level crop acreage can be used to derive better information on levels of the natural hedge.Originality/valueEven though the effects of data aggregation on price‐yield correlations have been discussed in earlier research, this paper is the first to also account for on‐farm effects of underlying crop acreage on levels of natural hedge. It is found that this simple relationship can be useful in risk management and modeling applications.
Hedging weather risk on aggregated and individual farm‐level
Authors: Erec Heimfarth Leif , Finger Robert , Musshoff Oliver 
Published: October 2012

PurposeSince the 1990s, there has been a discussion about the use of weather index‐based insurance, also called weather derivatives, as a new instrument to hedge against volumetric risks in agriculture. It particularly differs from other insurance schemes by pay‐offs being related to objectively measurable weather variables. Due to the absence of individual farm yield time series, the hedging effectiveness of weather index‐based insurance is often estimated on the basis of aggregated farm data. The authors expect that there are differences in the hedging effectiveness of insurance on the aggregated level and on the individual farm‐level. The purpose of this paper is to estimate the magnitude of bias which occurs if the hedging effectiveness of weather index‐based insurance is estimated on aggregated yield data.Design/methodology/approachThe study is based on yield time series from individual farms in central Germany and weather data provided by the German Meteorological Service. Insurance is structured as put‐option on a cumulated precipitation index. The analysis includes the estimation of the hedging effectiveness of insurance on aggregated level and on individual farm‐level. The hedging effectiveness is measured non‐parametrically regarding the relative reduction of the standard deviation and the value at risk of wheat revenues.FindingsFindings indicate that the hedging effectiveness of a weather index‐based insurance estimated on aggregated level is considerably higher than the realizable hedging effectiveness on the individual farm‐level. This refers to: hedging effectiveness estimated on the aggregated level is higher than the mean of realized hedging effectiveness on the individual farm‐level and almost every evaluated individual farm in the analysis realizes a lower hedging effectiveness than estimated on the aggregated level of the study area. Nevertheless, weather index‐based insurance designed on the aggregated level can lead to a notable risk reduction for individual farms.Originality/valueTo the authors’ knowledge, this paper is the first that analyzes the influence of crop yield aggregation with regard to the hedging effectiveness of weather index‐based insurance.

Published: October 2012

PurposeThe purpose of this study was to investigate the effect of information on English consumers' evaluation of fresh and thawed cod fillets which in English retail stores is referred to as “chilled” seafood.Design/methodology/approachAfter the exploration of consumers' impressions of thawed fish, this study followed a pair‐wise comparison approach in a central location consumer test. Fish fillets were evaluated on liking, smell and texture by means of a questionnaire with additional behavioural and attitudinal questions.FindingsThis study showed that consumers in England may prefer thawed over fresh cod fillets without information. However, consumers' evaluations increased for labelled fresh cod fillets and decreased for thawed. Finally, consumers reported positive expectations about fillets labelled “fresh” or “frozen at sea”.Research limitation/implicationsThis study involved testing cod fillets in a central location test. Consumers do not usually evaluate cod fillets in this way in their daily life. The quality of the two types of fillets made especially for this test may vary compared to the ones usually sold and consumed.Practical implicationsThis study can inform producers and retailers about what to expect by means of sales of fresh and thawed cod products with or without information.Social implicationsIt was shown that consumers are positively influenced by information and are willing to consume more fish if they know that the fish is fresh or thawed properly.Originality/valueThis is the first paper to present English consumers' evaluations of thawed cod.
