A Study of Analyst-Run Mutual Funds: The Abilities and Roles of Buy-Side Analysts

We assess the abilities and the role of buy-side analysts within mutual fund families by analyzing mutual funds managed by buy-side analysts from fourteen fund families. Buy-side analysts exhibit investment abilities by realizing positive style- and risk-adjusted returns and generating superior risk-return tradeoffs. Analysts' skills have a positive impact on the performance of funds from the same family. Although some managers benefit from closely following their buy-side analysts' ideas, research generated by these analysts is generally being underutilized by affiliated managers. The underutilization is consistent with longer-tenured managers choosing to forgo some of the analysts' ideas due to career considerations.
Evaluating the potential of renewable energy technologies for buildings in Nigeria

The impact of greenhouse gas emission resulting from burning of fossil fuel for electricity generation is a global challenge that can be tackled by using renewable energy sources. Nigeria is a fast growing country with population estimated at about 140 million people. Steady economic and population growth is putting significant strain on the country’s electricity supply and distribution infrastructure. More than 64% of Nigeria’s electricity is generated from fossil fuel sources. However, the direct cost of infrastructure required for generation, transmission and the environmental implication of burning additional fossil fuel will have significant impact on the country’s rate of growth and the global carbon dioxide emission. Abundant renewable energy sources all over the country can be utilised to reduce greenhouse gas emissions as well as a strategy for rural electrification. One of the key constraints affecting the use of alternative or renewable energy technologies is the lack of understanding of the factors that affect performance of the system. To remove this constraint, the potential of solar PV systems have been evaluated using the TRNSYS Simulation Environment and RETSCREEN Simulation Tool to establish performance data for a range of solar PV products and locations. Results show that PV systems have significant potential as stand alone applications in buildings and other application.
A narrative analysis of educators’ lived experiences of motherhood and teaching

In this article we argue that mothers often construct images of what they perceive as society’s expectations of them. These images become the parameters in the eyes of society to which they aspire. This is reminiscent of the adage: “I am not who you think I am. I am not who I think I am. I am who I think you think I am”. This study is based on analysis of the life-stories of four professional female educators. These mother-educators shared their assumptions, cultural values and beliefs and showed how these shaped the subjective construction and harmonisation of the multiple roles of mother and educator. It was found that they often find themselves faced with the conflicting and complementary dimensions of the multiple roles of mother and professional. We contend that these mothers set high standards and expectations for themselves as mother-educator and they worry about failing, not only themselves, but also ‘others’. They see the world of work, including parents, educators and school principal, as being against them — which is possibly a manifestation of a faltering self-image and linked to feelings of inadequacy. It is argued that mother educators need to negotiate new meaning in terms of their own perceived multiple role expectations so as to enable them to experience success as both homemakers and professionals. The challenge for the mother then is to engage in a constant search for her own identity.
A customized construct of sequential service quality in service encounter chains: time, context, and performance threshold

Studies of the construct of service quality have traditionally been undertaken from the perspective of the service receiver. More recently, research has focused on both the service provider's perspective and the service receiver's perspective. In addition, there have also been some triadic network approaches to the study of service quality. However, there has been very little research into sequential service quality in service‐encounter chains (that is, consecutive service performances in a series of service encounters). The incorporation of connected service encounters in services management can improve understanding of sequential service quality in service‐encounter chains. This paper provides a customized construct of sequential service quality and highlights the importance of time, context, and performance threshold in service‐encounter chains. Furthermore, the paper presents a generic five‐phase performance process, and a customized six‐dimensional construct of sequential service quality.
Strategies and effectiveness of diabetes self-management education interventions for Bangladeshis

The study aimed to review the evidence regarding the effectiveness of diabetes health-education trategies used for Bangladeshi populations, who are among the most susceptible of the UK communities for developing diabetes, and unfortunately receive inequitable care. Reducing health inequalities and improving health education for patients living with chronic conditions is central to national policy, and the National Service Framework for Diabetes has set nationwide standards for diabetes health education. The development of effective structured patienteducation programmes is an important public health challenge, and more so for hard-to-reach black and minority ethnic (BME) groups. Such programmes rely on the evidence base, and this review sets out to investigate the effectiveness of health-education strategies used for a vulnerable and particularly high-risk group. The literature was searched using the following databases from inception to August 2008: AMED, CAB Abs, CINAHL, EMBASE, vidMEDLINE(R), PsycINFO, DARE. Cochrane, NIH and the NHS ethnicity and health library. Two reviewers independently assessed studies for inclusion in the review against the following inclusion criteria: a health-education intervention of any setting and type with the aim of providing diabetes-related health education to Bangladeshis. Data were extracted on the participants, interventions, delivery methods, comparison groups and outcome measures. The search strategy revealed four interventions. The authors of the only randomised controlled trial explain that a community lay-led intervention in providing diabetes education was successful, but the benefits were restricted due to a lack of uptake and attendance. Three others have qualitatively described the beneficial effects of link workers/health advocates within the communities, but have not systematically reported outcome measures. The small number of studies retrieved, and the heterogeneity between the studies, make it difficult to make recommendations on particular strategies that are most beneficial to this group. There is an urgent need for further quantitative and qualitative research, including formative, process and outcome evaluations, in order to ascertain the most effective education models for specific minority groups, especially for those who are disadvantaged and more susceptible to disease progression.
Temporal changes in bacterial rRNA and rRNA genes in Delaware (USA) coastal waters

The diversity and abundance of bacterial 16S rRNA genes (rDNA) and associated 16S rRNA were assessed to examine community structure and potential activity in a 2 yr seasonal study of marine surface waters along the Delaware (USA) coast. The majority of the ribotypes appearing as rRNA or rDNA were present at least 50% of the time, and their variation over time was less than that of most biotic and abiotic factors. Even though there were no predictable seasonal patterns in com- munity structure, environmental parameters explained between 40 and 50% of the observed varia- tion in community structure. In general, summer communities correlated positively with temperature, light, bacterial production, and phosphate levels, while winter communities correlated with dissolved organic carbon concentrations. The abundance of 3 select ribotypes (SAR11, a Cytophaga subgroup, SAR116-like) varied some over time as measured by quantitative PCR (qPCR). The SAR11 clade was 10 times more abundant than the other 2 groups. However, the 16S rRNA to rDNA ratios, as mea- sured by qPCR and reverse transcription-qPCR, varied greatly over time and were highest in the SAR11 population and the Cytophaga subgroup. The rRNA to rDNA ratio of the Cytophaga subgroup and SAR116-like group significantly correlated with some environmental parameters. Taken together, these results suggest that the community composition of the major members does not change much over time, but individual members do vary in abundance and activity and can be influ- enced by environmental factors.
Impact tensile cracking behavior of oxide scale in Q235 strip iron

Scanning electron microscopy (SEM) is used to observe the fracture surface morphology of Q235 steel. The cracking law/crack rule principle of strip surface under tension is studied via universal tensile testing machine. The results show that the thickness of the scale is relatively uniform, about 10 μm, and the structure is dense and well attached to the matrix. Tensile experiments show that as the strain increases, the cracks increase slowly in the initial stage, rapidly in the middle period, and slowly in the final period. When the strain exceeds 0.15%, the cracks are difficult to increase. In order to avoid direct erosion of the abrasive on the substrate, a reasonable range of tension setting should be 0.15%-0.18% in the pretreatment process without acid descaling.
Tanousia zrmanjae (Brusina, 1866) (Caenogastropoda: Truncatelloidea: Hydrobiidae): a living fossil

A living population of Tanousia zrmanjae (Brusina, 1866) was found in the mid section of the Zrmanja River in Croatia. The species, found only in the freshwater part of the river, had been regarded as possibly extinct. A few collected specimens were used for this study. Morphological data confirm the previous descriptions and drawings while molecular data place Tanousia within the family Hydrobiidae, subfamily Sadlerianinae Szarowska, 2006. Two different sister-clade relationships were inferred from two molecular markers. Fossil Tanousia, represented probably by several species, are known from interglacial deposits of the late Early Pleistocene to the early Middle Pleistocene of several European countries. Thus T. zrmanjae may be regarded as a living fossil restricted to the short section of the Zrmanja River. key wordS: protoconch, radula, reproductive organs, DNA, COI, 18S, phylogeny, Pleistocene
Effects of combination gene therapy system pcDNA3.1(-)-shVEGF/yCDglyTK on proliferation of gastric cancer cells

The U6-shRNA expression cassette of pGenesil-1-hVEGF4-shRNA was subcloned into the skeleton vector, fusion suicide gene pCDNA3.1(-)-CV-yCDglyTK synthesized in preliminary studies to establish the combination gene therapy system pCDNA3.1(-)-shVEGF/yCDglyTK, so as to investigate the effects of the combination gene therapy system on proliferation and apoptosis of gastric cells. MTT assay showed that cell growth in the pcDNA3.1(-)-CV-yCDglyTK and pcDNA3.1(-)-shVEGF/yCDglyTK groups was significantly inhibited. Compared with cells transfected with pcDNA3.1(-)-CV-yCDglyTK, cells transfected with pcDNA3.1(-)-shVEGF/yCDglyTK were more sensitive to 5-fluorocytosine (5-FC) (P < 0.05). Flow cytometry indicated that the apoptotic rate of SGC7901 cells in the pcDNA3.1(-)shVEGF/yCDglyTK group was as high as (67.9 ± 4.78)%, which was significantly higher than the other four groups (P < 0.05). The combination gene therapy system pcDNA3.1(-)-shVEGF/yCDglyTK can effectively suppress SGC7901 cell proliferation and induce apoptosis of these gastric cancer cells, the effects of which is higher than simple RNA interference (RNAi) or suicide gene therapy.
Essays on pig production efficiency and farmers' financial decisions under uncertainty

Recent structural changes in agricultural production towards fewer, but larger, units pose challenges for farmers in decision making about practical production and about managerial practices to increase efficiency, which are vital for farm productivity and profitability. In studies using mathematical programming and econometric models, this thesis evaluated farm-specific characteristics related to the individual technical efficiency (TE) of each input and output factor and of managerial characteristics associated with persistent TE (PTE) and residual TE (RTE). Regarding farm-specific variables, the results indicated that advisory services, farm location and most housing practices were not significant for technical efficiency, with the exception of recent technology such as heated floors. Use of written instructions on feeding and in preventing infectious diseases was associated with higher technical efficiency. For the best results, decision makers should use separate approaches depending on pig production specialisation and the input or output efficiency requiring improvement. Regarding managerial practices, managerial experience, economy-driven goals and use of strategic management accounting practices were drivers of PTE. In contrast, conducting bookkeeping checks more frequently and focusing on meeting market demands in terms of quality were negatively associated with PTE. Joint time significance evaluation of lagged individual technical efficiency on variables of structural change in the regression model confirmed the long-term nature of investments in Swedish pig farming. Under uncertainty, decisions made by farmers may be biased, producing suboptimal solutions. For example, illusion of control can give a sense of controlling power in situations where the outcome is determined by chance. Alternative ways to collate and analyse data are needed to evaluate behaviours under uncertainty. Presence of illusion of control in farmers’ financial decisions was explored in a study with a framed economic experimental design, survey data and a psychological scale. The results did not indicate the presence of illusion of control in the sample of Swedish farmers studied. The outcome measures showed low levels of correlation, suggesting that different methods and measurement instruments are complements, rather than substitutes. Findings provide information that could help farmers in their complex production and managerial decisions.

A cross-sectional analysis of industrialization and growth in Africa

Industrialization, particularly manufacturing, has been identified as an engine of growth. The industrial revolution and the dynamic growth of East Asian economies attest to this. The paper finds that the structure of industry in most African economies, with the exception of the Southern African economies and the Eastern African economies, are geared more towards mining and utilities industries rather than manufacturing which is more growth stimulating. Based on the Lewis –Kaldor theoretical framework, this paper employs cross sectional analysis of 54 African countries to draw the linkages between industrialization and growth. The regression analyses confirm the relationship between industrial development and economic growth. However, industrial development on the African continent has no transfer effects across member countries. Policy attention should therefore focus on manufacturing and the domestic private sector.
Tensile properties of earlywood and latewood from loblolly pine (Pinus taeda) using digital image correlation

The goal of this research was to measure the elastic properties and strength of earlywood and latewood from two growth-ring positions of loblolly pine. Because of the small specimen size, a contactless strain measurement was applied using a microscope with an appropriate field of view. The tensile properties of the earlywood and latewood were calculated from load data from a Minimat tester coupled with elastic strain data from a digital image correlation technique. Incremental loading was applied until specimen failure occurred. Elastic modulus, Poisson ratio, and strength generally increased as the growthring numbers increased, except for the strength of latewood that slightly decreased. Elastic properties and strength were significantly different for different growth-ring positions and intraring layers. The elastic modulus for earlywood and latewood were best fitted by Weibull distributions regardless of growth-ring positions, whereas Poisson ratios were best fitted by Weibull distributions for earlywood 1 - 10 and latewood 11 - 20 groups, and gamma distributions for earlywood 11 - 20 and latewood 1 - 10 groups. Strain distribution analysis showed nonuniform strain distributions for the four groups and also showed more resistance to load for earlywood and latewood from a higher growth-ring position.
Effect of addition of organic and inorganic combinations to soil on growing property of greenhouse cucumber

This research was carried out using a completely randomized design with seven treatments and seven replications. The treatments were perlite‚ date palm waste, soil, perlite + soil (Pe + s, w/w= 5/95), perlite + soil (w/w = 10/90), date palm waste + soil (w/w = 5/95) and date palm waste + soil (Pa+s, w/w= 10/90). The physiochemical characteristics of substrates were measured before plant cultivation. Some growth indices were measured at the end of the growth period. The results show that the amount of cucumber yield, number of fruit, biomass weight, plant height, stem diameter of plant and leaf area index in date palm wastes were highest. The amount of fruit stiffness index in date palm wastes and perlite media were highest but the amount of fruit total soluble solids (TSS) in date palm wastes media was lowest and had significant difference with other substrates. The concentration of P, K and Ca in all substrates had no significant difference. The concentration of Mg in Pa+s (w/w=10/90) and Pe + s (w/w= 5/95) substrates had the lowest content and had significant differences as compared with other treatments. The concentration of Fe, Mn and Zn in plant leaf in perlite media was higher than for the other treatments. Keywords: Date palm waste, perlite, substrate, greenhouse, cucumber
The Danish National Tests – A Practical Guide

In 2010, the Danish National Tests were implemented in the public compulsory schools as a mean of evaluating the performance of the public school system. The extensive test program consists of ten mandatory tests in six subjects in grades 2 through 8. In this paper, we share our insights from working with the first four rounds of the test data. We provide a brief introduction to adaptive testing, the available data and general data issues including missing data, test participation and data transformations. Additionally, we construct a standardized measure of the raw pupil ability estimate within each test and argue that this is often a more feasible measure for data analyses compared to the transformed test score presented to pupils and teachers. We provide the reader with preliminary analyses of the relation between pupils’ national test results and a wide range of pupil background characteristics as well as pupils’ 9th grade examination marks. We document a stable test score gap across grade levels and socio economic background and discuss the prospects of the national test data for future research.
A comparison of observed and simulated absorption from H I, C IV, and Si IV around z ≈ 2 star-forming galaxies suggests redshift–space distortions are due to inflows

We study H I and metal-line absorption around z ≈ 2 star-forming galaxies by comparing an analysis of data from the Keck Baryonic Structure Survey to mock spectra generated from the Evolution and Assembly of Galaxies and their Environments (EAGLE) cosmological, hydrodynamical simulations. We extract sightlines from the simulations and compare the properties of the absorption by H I, C IV, and Si IV around simulated and observed galaxies using pixel optical depths. We mimic the resolution, pixel size, and signal-to-noise ratio of the observations, as well as the distributions of impact parameters and galaxy redshift errors. We find that the EAGLE reference model is in excellent agreement with the observations. In particular, the simulation reproduces the high metal-line optical depths found at small galactocentric distances, the optical depth enhancements out to impact parameters of 2 proper Mpc, and the prominent redshift–space distortions which we find are due to peculiar velocities rather than redshift errors. The agreement is best for halo masses ∼10^(12.0) M⊙, for which the observed and simulated stellar masses also agree most closely. We examine the median ion mass-weighted radial gas velocities around the galaxies, and find that most of the gas is infalling, with the infall velocity depending on halo rather than stellar mass. From this, we conclude that the observed redshift–space distortions are predominantly caused by infall rather than outflows.
Influence of quinoa roasting on sensory and physicochemical properties of allergen‐free, gluten‐free cakes

Summary The objectives of this study were to determine pasting properties of non-roasted (NR) and roasted quinoa (RQ) and to investigate the effect of RQ on consumer acceptance and physicochemical properties of an allergen-free, gluten-free cake formulation. Quinoa seeds were roasted at 177 °C for 15 (R15), 30 (R30) and 45 min (R45), and flours were analysed for pasting properties. Five cakes including a commercial chocolate cake (CCC) and cakes made with NR and RQ flours were evaluated for preference by fifty panelists. Quality parameters included colour, water activity, moisture content, firmness, weight and height. Peak and final viscosity increased with roasting time. The NR cake had the highest sensory scores for appearance, colour and texture. On flavour and overall acceptability, CCC was the highest. Regarding quality data, CCC, NR and R15 cakes had similar L* values, while CCC had the lowest a*, b*, aw, moisture content and firmness values.
