Debt and Growth: Is There a Non-Monotonic Relation?

In this note we theoretically investigate the question of whether the relationship between public debt and economic growth is characterized by an inverse U-shaped functional form. Starting point of our analysis is the paper by Checherita-Westphal et al. (2012) who present an endogenous growth model with public capital and public debt that displays a hump-shaped relation between debt and economic growth. We highlight the mechanism that generates this outcome and we generalize their model by allowing for a more general debt policy. We demonstrate that this nonmonotonic relation only holds if public deficits are exogenously fixed and exactly equal to public investment at each point in time. With a more general debt policy, one realizes that smaller public deficits and lower public debt always lead to a higher balanced growth rate. Thus, starting from a situation where the public deficit equals public investment, governments can raise the long-run growth rate by reducing their deficits.
Rules of (household) engagement: technology as manager, assistant and intern

PurposePractitioners need to understand how households will engage with connected-home technologies or risk the failure of these innovations. Current theory does not offer sufficient explanation for how households will engage; hence, this paper aims to address an important gap by examining how households set “rules of engagement” for connected-home technologies in the context of electricity use and monitoring.Design/methodology/approachA review of the extant psychology, technology and engagement literature is conducted and yields two research questions for exploration. The research questions are addressed via 43 in-depth household interviews. Analysis includes thematic analysis and computerized text analysis.FindingsThe results include a typology of technology engagement (the “PIP typology”) and discuss three main roles for technology in assisting households: intern, assistant and manager. Key contributions are as follows: consumers in household settings may experience “compromised engagement” where the perceived middle option is selected even if no-one selected that option originally; households open to using connected-home technologies are often taking advantage of their ability to “delegate” engagement to technology, and because consumers humanize technology, they also expect technology to follow social roles and boundaries.Research limitations/implicationsFuture research may examine the PIP typology quantitatively and/or in different contexts and would benefit from a longitudinal study to examine how household technology engagement evolves. Four research propositions are provided, which may form the basis for future research.Practical implicationsRecommendations for practitioners are presented regarding the benefits of keeping consumers at the heart of connected-home technology goods and services. Specific design principles are provided.Originality/valueThis paper fulfills the need to understand how households will engage with connected-home technologies and the roles this technology may fulfill in the complex household service system.
Recent Advances in Thyroid Hormone Regulation: Toward a New Paradigm for Optimal Diagnosis and Treatment

In thyroid health, the pituitary hormone thyroid-stimulating hormone (TSH) raises glandular thyroid hormone production to a physiological level and enhances formation and conversion of T4 to the biologically more active T3. Overstimulation is limited by negative feedback control. In equilibrium defining the euthyroid state, the relationship between TSH and FT4 expresses clusters of genetically determined, interlocked TSH–FT4 pairs, which invalidates their statistical correlation within the euthyroid range. Appropriate reactions to internal or external challenges are defined by unique solutions and homeostatic equilibria. Permissible variations in an individual are much more closely constrained than over a population. Current diagnostic definitions of subclinical thyroid dysfunction are laboratory based, and do not concur with treatment recommendations. An appropriate TSH level is a homeostatic concept that cannot be reduced to a fixed range consideration. The control mode may shift from feedback to tracking where TSH becomes positively, rather than inversely related with FT4. This is obvious in pituitary disease and severe non-thyroid illness, but extends to other prevalent conditions including aging, obesity, and levothyroxine (LT4) treatment. Treatment targets must both be individualized and respect altered equilibria on LT4. To avoid amalgamation bias, clinically meaningful stratification is required in epidemiological studies. In conclusion, pituitary TSH cannot be readily interpreted as a sensitive mirror image of thyroid function because the negative TSH–FT4 correlation is frequently broken, even inverted, by common conditions. The interrelationships between TSH and thyroid hormones and the interlocking elements of the control system are individual, dynamic, and adaptive. This demands a paradigm shift of its diagnostic use.
Behavioral Activity of Catnip (Lamiaceae) Essential Oil Components to the German Cockroach (Blattodea: Blattellidae)

Abstract The essential oil of catnip, Nepeta cataria L. , contains two isomers of nepetalactone, E,Z- and Z,E-nepetalactone, and was tested for repellent activity to adult male German cockroaches, Blattella germanica (L.), in a choice-test arena. The two isomers of nepetalactone were purified by using preparative thin-layer chromatography and tested for behavioral activity in the choice-test arena. Significant differences due to concentration were detected by analysis of variance, and the responses were compared by least-squared means analysis. The activities of the essential oil and purified isomers were compared with N,N-diethyl-3-methylbenzamide (DEET) by a paired t-test. E,Z-Nepetalactone was the most active of the compounds tested, being significantly more active to this species than equivalent doses of DEET, the essential oil, or Z,E-nepetalactone. Antennectomized insects showed no response to concentrations that were active against intact insects.
Randomised controlled study of two different techniques of skin suture in endoscopic release of carpal tunnel

In a prospective, randomised trial of 54 hands in 47 patients incisions were randomised to be closed by either absorbable subcuticular (polyglytone 6211, Caprosyn®), or non-absorbable interrupted (polybutester, Novafil®), sutures after single-portal endoscopic release of the carpal tunnel. There was a significant reduction in pain scores on days 1 and 2 in the patients treated with an absorbable continuous subcuticular suture, and no difference in inflammation or infection. There was no difference in the cosmetic appearance between the two groups after three months.
Is Trading Fast Dangerous?

This chapter discusses the findings of the growing theoretical and empirical literature on trading speed in financial markets. The speed of trading has increased significantly in recent years, due to progress in information technologies and automation of the trading process. This evolution raises many questions about the effects of trading speed. It is argued that an increase in trading speed raises adverse selection costs but increases competition among liquidity providers and the rate at which gains from trade are realized. Thus, the effect of an increase in trading speed on market quality and welfare is inherently ambiguous. This observation is important for assessing empirical findings regarding the effects of trading speed and policy-making.

Ghrelin, insulin sensitivity and postprandial glucose disposal in overweight and obese children.

OBJECTIVE To explore the changes of ghrelin circulating levels induced by a mixed meal and their relationship with postprandial substrate oxidation rates in overweight and obese children with different levels of insulin sensitivity. METHODS A group of ten boys (age 9-12 years) with different levels of overweight (standard deviation score of body mass index: 1.6-3.2) was recruited. Body composition was measured by dual-energy X-ray absorptiometry. Insulin sensitivity was assessed by a frequently sampled i.v. glucose tolerance test. Pre-prandial and postprandial (3 h) substrate oxidation was measured by indirect calorimetry. The energy content of the test meal (16% protein, 36% carbohydrate and 48% fat) was 40% of pre-prandial energy expenditure (kJ/day). RESULTS Pre-prandial serum concentration of total ghrelin was 701.4+/-66.9 pg/ml (S.E.M.). The test meal induced a rapid decrease in ghrelin levels and maximal decrease was 27.3+/-2.7% below baseline. Meal intake induced a progressive increase of the carbohydrate oxidation rate for 45 min after food ingestion, followed by a slow decrease without returning to pre-prandial values. Postprandial cumulative carbohydrate oxidation was 16.9+/-0.8 g/3 h. Insulin sensitivity and postprandial maximal decrease of ghrelin concentration showed a significant correlation (r = 0.803, P < 0.01). Moreover, the postprandial carbohydrate oxidation rate correlated with the area under the curve for both insulin (r = 0.673, P < 0.03) and ghrelin (r = -0.661, P < 0.04). CONCLUSIONS A relevant association between postprandial insulin-mediated glucose metabolism and ghrelin secretion in children with different levels of overweight was found. It is possible that the maintenance of an adequate level of insulin sensitivity and glucose oxidation may affect appetite regulation by favoring a more efficient postprandial ghrelin reduction.
Factors differentiating between concentric and sprinkled multiple-patronage shoppers in Kuwait

Abstract Two types of hypermarket spenders with multi-patronage behavior were identified; namely, “Concentric” and “Sprinkled. ” The objective of this study is to examine which of hypermarket store attributes differentiate between the two types of spenders, and to determine the differences of their demographic characteristics. Six store attributes including the depth of the product assortment, store services, location convenience, sales promotion, prices, and store reputation were examined. Also, five different demogrpaphics were tested including gender, nationality, marital status, education and monthly income. A cross sectional design with an intercept survey was used. Three hundered cusdtomers were intercepted at diffeerent hypermarket store locations and asked to fill out the survey instrument. Two research hypotheses were tested using the survey data. The interpretation of the discriminant function showed that “concentric” spenders score quite high on store services, moderately on convenience and sales promotion, and low on prices. Both product assortment depth and store reputation were not important to the discriminant function interpretation. Results also indicated that only two demographics were significantly differentiating between the two types of spenders. Several recommendations were made based on the study findings to enable each hypermaqrket store in Kuwait to increase its share of a consumer’s wallet.
Nutritional impacts of a fruit and vegetable subsidy programme for disadvantaged Australian Aboriginal children

Healthy food subsidy programmes have not been widely implemented in high-income countries apart from the USA and the UK. There is, however, interest being expressed in the potential of healthy food subsidies to complement nutrition promotion initiatives and reduce the social disparities in healthy eating. Herein, we describe the impact of a fruit and vegetable (F&V) subsidy programme on the nutritional status of a cohort of disadvantaged Aboriginal children living in rural Australia. A before-and-after study was used to assess the nutritional impact in 174 children whose families received weekly boxes of subsidised F&V organised through three Aboriginal medical services. The nutritional impact was assessed by comparing 24 h dietary recalls and plasma carotenoid and vitamin C levels at baseline and after 12 months. A general linear model was used to assess the changes in biomarker levels and dietary intake, controlled for age, sex, community and baseline levels. Baseline assessment in 149 children showed low F&V consumption. Significant increases (P< 0·05) in β-cryptoxanthin (28·9 nmol/l, 18 %), vitamin C (10·1 μmol/l, 21 %) and lutein–zeaxanthin (39·3 nmol/l, 11 %) levels were observed at the 12-month follow-up in 115 children, although the self-reported F&V intake was unchanged. The improvements in the levels of biomarkers of F&V intake demonstrated in the present study are consistent with increased F&V intake. Such dietary improvements, if sustained, could reduce non-communicable disease rates. A controlled study of healthy food subsidies, together with an economic analysis, would facilitate a thorough assessment of the costs and benefits of subsidising healthy foods for disadvantaged Aboriginal Australians.
Exploring Determinants of Productivity in Pakistani Manufacturing Firms

This study examines the determinants of productivity among manufacturing firms in Pakistan using firm level data gathered in the World Bank Enterprise Survey of 2007. The research econometrically investigates the impact of various structural, organizational and technological characteristics of firms on the level of Total Factor Productivity (TFP). Findings of The study suggest thatfactors which enhance the firms’ performance and level of productivity include; foreign ownership, use of information and communication technology, schooling of production workers, presence of labor welfare programs, access to international market and use of innovative production process. In contrast, unionization of workforce and power outages are negatively associated with TFP
Embedding research in clinical practice: differences in attitudes to research participation among clinicians in a tertiary teaching hospital

Despite a drive to increase research in healthcare settings, clinician participation in research remains infrequent. This paper describes an online survey comparing attitudes with research participation among clinicians (doctors, nurses and allied health professionals) at an Australian tertiary children's hospital. Differences between professional groups support the existence of different professional cultures surrounding research, suggesting that multiple strategies are required to improve participation in research.
Removal of Copper and Zinc Ions onto Biomodified Palm Shell Activated Carbon

commercially produced in Malaysia granular palm shell activated carbon (PSAC) was biomodified with bacterial biomass (Bacillus subtilis) to produce a hybrid biosorbent of higher efficiency. The obtained biosorbent was evaluated in terms of adsorption capacity to remove copper and zinc metal ions from aqueous solutions. The adsorption capacity was evaluated in batch adsorption experiments where concentrations of metal ions varied from 20 to 350 mg/L. A range of pH from 3 to 6 of aqueous solutions containing metal ions was tested. Langmuir adsorption model was used to interpret the experimental data. Comparison of the adsorption data of the biomodified and original palm shell activated carbon showed higher uptake of metal ions by the hybrid biosorbent. A trend in metal ions uptake increase with the increase in the solution's pH was observed. The surface characterization data indicated a decrease in the total surface area for the hybrid biosorbent; however the uptake of copper and zinc by it was at least equal to the original PSAC at pH 4 and 5. The highest capacity of the hybrid biosorbent was observed at pH 5 and comprised 22 mg/g and 19 mg/g for copper and zinc, respectively. The adsorption capacity at the lowest pH of 3 was significantly low. The experimental results facilitated identification of potential factors influencing the adsorption of copper and zinc onto biomodified and original palm shell activated carbon.
The baculovirus transactivator IE1 binds to viral enhancer elements in the absence of insect cell factors

The transregulatory IE1 protein of Autographa californica nuclear polyhedrosis virus binds to the viral enhancer element hr5. To test whether IE1 binds independently of host cell factors, IE1 was translated in rabbit reticulocyte extracts and tested for DNA binding activity by an electrophoretic mobility shift assay. Complexes with the hr5 probe were detected with translation reaction mixtures primed with ie1 RNA but not with control translation reaction mixtures. However, the DNA-protein complexes formed with IE1 translated in vitro migrated more slowly than complexes formed with IE1 that was transiently expressed in insect cells. Phosphatase treatment of the translation reactions resulted in an increase in the mobility of the DNA-protein complexes, suggesting that hyperphosphorylation was responsible for the altered migration. To further verify that IE1 was capable of binding DNA in the absence of host cell factors, an N-terminal truncation of IE1 was synthesized in vitro, and shown to interact with hr5. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of IE1 translated in vitro revealed that the mobility of the protein was heterogeneous. This pattern was altered by translation in the presence of an oligonucleotide corresponding to the IE1 specific binding site but was not affected by translation in the presence of a nonspecific DNA. These results suggest that binding of IE1 to DNA causes a conformational change in the protein that alters the accessibility of IE1 to protein kinases.
From Temporary Competitive Advantage to Sustainable Competitive Advantage

Both industrial organization theory (IO) and the resource-based view of the firm (RBV) have advanced our understanding of the antecedents of competitive advantage but few have attempted to verify the outcome variables of competitive advantage and the persistence of such outcome variables. Here by integrating both IO and RBV perspectives in the analysis of competitive advantage at the firm level, our study clarifies a conceptual distinction between two types of competitive advantage − temporary competitive advantage and sustainable competitive advantage − and explores how firms transform temporary competitive advantage into sustainable competitive advantage. Testing of the developed hypotheses, based on a survey of 165 firms from Taiwan's information and communication technology industry, suggests that firms with a stronger market position can only attain a better outcome of temporary competitive advantage whereas firms possessing a superior position in technological resources or capabilities can attain a better outcome of sustainable competitive advantage. More importantly, firms can leverage a temporary competitive advantage as an outcome of market position to improving their technological resource and capability position, which in turn can enhance their sustainable competitive advantage.
The reliability of hand-held dynamometry in measuring isometric strength of the shoulder internal and external rotator musculature using a stabilization device

Although hand-held dynamometry is considered an objective method of measuring strength, the reliability of the procedure can be compromised by inadequate tester strength and insufficient stabilization of the dynamometer and subject. The purpose of this study was to investigate the test-retest reliability of a hand-held dynamometer with the use of a portable stabilization device while testing the shoulder internal and external rotator musculature. The isometric strength of the shoulder rotator musculature was tested twice in 30 asymptomatic adult volunteers (15 male and 15 female) between 18 and 63 years of age by using an intrasession design. Consistency of the testing protocol was maintained through the use of an arm stabilization apparatus, which fixed the arm in 30° of the scapular plane and a portable dynamometer stabilization device. Intraclass correlation coefficients (ICC's) were high, ranging from ICC (3,1) = 0.971–0.972 for the test-retest trials of internal and external rotation. There was no significant difference between sessions one and two for maximum internal rotation (p = 0.431) and maximum external rotation strength (p = 0.780). The results indicate that the testing protocol with stabilization device is a reliable method for measuring strength of the internal and external rotator shoulder musculature.
Effect of family size and income on the biochemical indices of urban school children of Bangladesh.

The relationship between family size and income and the biochemical indices of 242 children (aged from 5 to 12 years) from five schools in Dhaka City, Bangladesh, was investigated. Socio-economic data were collected by questionnaire and blood samples were drawn by visiting each school on a prefixed date. Mean levels of all measures, except for serum zinc, fell within the normal range. Older boys, but not girls (10-12 years of age) had statistically significantly higher haemoglobin, serum protein and serum vitamin A levels compared with those of the younger boys (5-9 years of age). The children were divided into three family size groups (small, up to 4 members; medium, 5-7 members; and large, 8 or more) to investigate the effect of family size on the biochemical data. The children from smaller families showed significantly higher levels of haemoglobin and serum vitamin A compared with the children from large families. For serum protein, copper and zinc, there was no statistically significant difference between the children of different family size groups. To analyse the effect of family income, children were divided into three income groups (low, up to taka 2000; medium, taka 2001-4500; and high, 4501 or more). The children from the low family income group had significantly lower serum protein (7.5 g/100 ml) and haemoglobin (13.4 g/100 ml) levels compared with those of the children from the high family income group (for protein, 7.7 g/100 ml and haemoglobin, 14.1 g/100 ml).
