Illegal fishing and catch potentials among small-scale fishers: application of an endogenous Switching regression model
Authors: Akpalu Wisdom , Normanyo Ametefee K. 
Published: October 2013

AbstractCapture fish stocks are facing an increasing threat of extinction, partly due to the use of illegal fishing methods. In developing coastal countries – where fishing activities are the mainstay of the population along the coast – livelihoods are being directly threatened. Although a number of studies exist on fishing regulations and those who violate them, little has been done on the relationship between intrinsic catch potentials/fishing skills and illegal fishing behavior. Using data on violations of light attraction regulation among small-scale fishers in Ghana, our results show that the risk of punishment, the amount of fishing experience, the skipper's age, and religious norms all influence the decision to violate fishing regulations. Most importantly, we found that violators and non-violators have different fishing skills. Consequently, policies targeting illegal fishing must focus on equalizing efficiency and/or fishing skills among the fishermen as well as on traditional variables that influence violation decisions.
Charge-dependent secretion of an intrinsically disordered protein via the autotransporter pathway
Authors: Kang’ethe Wanyoike , Bernstein Harris D. 
Published: October 2013

Significance
Bacterial autotransporter proteins contain a large segment that is transported from the periplasm (the space between the inner and outer membranes) to the extracellular milieu. Because the periplasm lacks ATP, the energy required for the transport reaction is thought to be derived from the folding of this segment following its secretion. Contrary to the prevailing view, we found that a heterologous polypeptide that cannot fold was secreted efficiently when it was fused to an autotransporter. Reducing the negative charge of this polypeptide, however, strongly impaired secretion. Our results identify net charge as a potentially important factor that drives autotransporter secretion.
After the financial crisis: a cost efficiency analysis of banks from Saudi Arabia
Authors: Hanif Akhtar Mohammad 
Published: October 2013

Purpose
– This paper aims to estimate the cost efficiency scores of banks in KSA before and during financial crisis by using a data envelopment analysis (DEA) approach.

Design/methodology/approach
– The study uses the intermediation approach of banking services where banks are considered as manufacturing units. The research methodology consists of cost efficiency DEA and a second stage Tobit regression model.

Findings
– The results reveal that banks in KSA are least affected by the crisis as the efficiency scores remain the same during all the periods. However, the average levels of inefficiency remain higher suggesting that KSA banks are lagging behind in exploiting the resources fully. The major source of cost inefficiency stems from allocative inefficiency rather than the technical one. Results of the Tobit regression also disclose that the impact of financial crisis across bank efficiency remains weak and inconclusive.

Research limitations/implications
– The study bears some useful managerial implications for various stakeholders. Although banks do not seem to be affected by the crisis, yet they need to improve their efficiency since the levels are far below the frontier. For successful existence and growth of banking, it remains vital that these banks control their costs regardless of the fact are operating in a concentrated market.

Practical implications
– The paper suggests that the banks in KSA need to bring down their operating expenses to reach the efficiency frontier. The average level of inefficiency (82 per cent) reflects a greater amount of input waste which needs to be controlled by these banks.

Originality/value
– The study is novel in a way that it evaluates the cost efficiency performance of KSA banks before and during the financial crisis, followed by a second stage regression on the determinants of cost efficiency. It provides valuable insights to both the bank managers and public policy makers who can look for the optimal levels of efficiency and competitiveness of Saudi banking sector.
Islamic rates of return and conventional interest rates in the Malaysian deposit market
Authors: Ito Takayasu 
Published: October 2013

Purpose– This paper aims to analyze Islamic rates of return, conventional interest rates in the Malaysian deposit markets, and Kuala Lumpur Interbank Offered Rate (KLIBOR) rates in the short-term money market from the view point of co-movement and transmission.Design/methodology/approach– The non-stationary time series models such as cointegration and Granger causality tests are applied to analyze the daily data.Findings– Islamic rates of return and conventional interest rates co-move in the Malaysian deposit market. The Islamic rates of return propel conventional interest rates in the three-, six-, and 12-month maturities. Islamic rates of return and conventional interest rates form a short-term money market with KLIBOR rates.Research limitations/implications– The author analyzes econometrically the sample period from May 16, 2005 to January 12, 2012. This paper concentrates on the period after the development of Islamic banking in Malaysia.Practical implications– Islamic and conventional deposit markets are competitive in Malaysia; in particular, the competition in the one-month deposit market is very keen. Islamic rates of return have more impact on the formation of short-term interest rates than conventional interest rates.Originality/value– This paper makes three contributions to the related literatures. First, it uses daily data in the maturities of one month, three months, six months and 12 months for its analyses. Second, it uses the Granger causality method of Toda and Yamamoto to avoid the issue of the non-stationarity of the data. The results of the Granger causality tests in this paper are different from related literatures. Third, this paper focuses on the relationship of KLIBOR rates and Islamic rates of return, and of KLIBOR rates and conventional interest rates.
Males' trust and mistrust of females in Muslim matrimonial sites
Authors: Al-Saggaf Yeslam 
Published: October 2013

Purpose– The aim of this study is to examine interpersonal trust in Muslim matrimonial sites (MMS) from a male perspective. Specifically how users perceive interpersonal trust in MMS; what are the signs of lack of trust in MMS (if any); and what strategies do users adopt to handle the lack of trust in MMS.Design/methodology/approach– This empirical qualitative study used ethnographic techniques to collect data. In addition to briefly observing five MMS, the study conducted semi-structured interviews with ten participants, who were all males, between the ages of 25-35, and residing in different locations, including the USA, the UK, the UAE, Australia and Bahrain. While the interviews focused on participants' experience in MMS, the analysis of these interviews focused on the issue of trust in these sites.Findings– The analysis has revealed that participants associated trust with “risk taking”, “reliance” on one's abilities, “self-confidence” and honesty with the first three being the major themes that transpired from the analysis of data. The analysis has also revealed three signs of lack of trust in MMS. Users expressed concern over a large number of members' profiles being fake; they appeared suspicious about these sites and approached them with caution and felt intimidated by the unrealistic expectations members placed on them. However, it was found users adopted several strategies to handle the lack of trust in MMS including using their communication skills to study others carefully, doing “police work” to uncover any inconsistencies in their statements, “interrogating” them using a pre-developed list of questions and involving their family members in their negotiations.Originality/value– Despite MMS immense popularity within the Islamic world, with the exception of a few articles, there are not many articles available in the academic literature on them. This article seeks to address this imbalance.
Open source assessment of academic library patron satisfaction
Authors: Angell Katelyn 
Published: October 2013

Purpose
– While academic libraries have often purchased proprietary software to assess patron satisfaction, the open source movement has generated high-quality software available free of charge. These tools are useful alternatives in an era marked by tremendous budget cuts familiar to many academic libraries. The purpose of this paper is to demonstrate the ability of open source software to effectively and affordably measure the quality of service at academic libraries.

Design/methodology/approach
– The author's experience with using the open source tool LimeSurvey to administer a library survey over a three-year period serves as a case study for other institutions. A literature review contextualizes the history of patron satisfaction surveys within academic libraries and questions the lack of an open source presence. Popular proprietary survey software is reported as a viable but expensive option, leading to a detailed case study of Sarah Lawrence College's successful addition of open source software to its assessment procedures.

Findings
– LimeSurvey is a flexible, customizable, and cost-effective tool for a small college library investing in querying its patrons for constructive feedback as a means of improving user experience.

Originality/value
– This paper will be of value to any library on a fixed budget looking to assess patron satisfaction with resources and services. Very little literature currently exists on this topic, but as the open source movement continues to flourish this software can play an integral role in allowing libraries to cut costs but not indispensable patron feedback.
Detection of Anthrax and Other Pathogens Using a Unique Liquid Array Technology
Authors: Schweighardt Andrew J. , Battaglia Amanda , Wallace Margaret M. 
Published: October 2013

AbstractA bead‐based liquid hybridization assay, Luminex® 100™, was used to identify four pathogenic bacteria, Bacillus anthracis, Clostridium botulinum, Francisella tularensis subsp. tularensis, and Yersinia pestis, and several close relatives. Hybridization between PCR‐amplified target sequences and probe sequences (located within the 23S ribosomal RNA gene rrl and the genes related to the toxicity of each bacterium) was detected in single‐probe or multiple‐probe assays, depending on the organism. The lower limits of detection (LLDs) for the probes ranged from 0.1 to 10 ng. Sensitivity was improved using lambda exonuclease to digest the noncomplementary target strand. All contributors in 33 binary, ternary, and quaternary mixtures in which all components were present in a 1:1 ratio were identified with an 80% success rate. Twenty‐eight binary mixtures in which the two components were combined in various ratios were further studied. All target sequences were detected, even when the minor component was overshadowed by a tenfold excess of the major component.
A Test of a Recently Devised Method of Estimating Skeletal Age at Death using Features of the Adult Acetabulum
Authors: Mays Simon 
Published: October 2013

AbstractEstimation of age at death from adult skeletal remains is highly problematic, due in great part to interpopulation variability in skeletal age changes. Thorough testing of aging methods is therefore of key importance. A method recently devised by Calce (Am J Phys Anthropol 148 (2012): 11–23) for placing adult skeletons into three broad age at death classes (17–39, 40–64, 65+ years) on the basis of acetabular morphology is tested on a collection of 18–19th century AD skeletons (N = 185) of documented age at death from London. Results showed that 45% were correctly assigned to age class using this method. This compares with 81% reported by Calce on 20th century North American material. This indicates significant interpopulation differences in the relationship between the Calce acetabular variables and age, even between populations of European ancestry. Until the sources of this variation are better understood, caution should be used before applying this method to estimate age in unknown skeletons.
Use of Craniofacial Superimposition in Historic Investigation
Authors: Bailey James A. , Brogdon G. B. , Nichols Brandon 
Published: October 2013

AbstractA skeleton discovered in Grand Forks, North Dakota was purported to belong to Clelland “Clell” Miller, a James‐Younger gang member, who was killed during the Northfield Bank robbery on September 7, 1876. A 3‐D image from a computer tomography (CT) scan of the skull was obtained, and a craniofacial superimposition was conducted to determine if the skull could belong to Miller. The superimposition method used in this case was to overlay the CT image of the skull onto Miller's postmortem photograph. In addition to the craniofacial superimposition, the images were juxtaposed to compare similarities or differences in facial morphology between the skull and photograph. Superimposition methods can be used to exclude identifications; however, they should not be used as a conclusive method for identification. In this case, there were sufficient similarities between the skull and Miller's photograph; therefore, the skull could not be eliminated as possibly being that of Miller.
The Discrimination of Colored Acrylic, Cotton, and Wool Textile Fibers Using Micro‐Raman Spectroscopy. Part 1: In situ Detection and Characterization of Dyes
Authors: Buzzini Patrick , Massonnet Genevieve 
Published: October 2013

AbstractRaman spectroscopy has been applied to characterize fiber dyes and determine the discriminating ability of the method. Black, blue, and red acrylic, cotton, and wool samples were analyzed. Four excitation sources were used to obtain complementary responses in the case of fluorescent samples. Fibers that did not provide informative spectra using a given laser were usually detected using another wavelength. For any colored acrylic, the 633‐nm laser did not provide Raman information. The 514‐nm laser provided the highest discrimination for blue and black cotton, but half of the blue cottons produced noninformative spectra. The 830‐nm laser exhibited the highest discrimination for red cotton. Both visible lasers provided the highest discrimination for black and blue wool, and NIR lasers produced remarkable separation for red and black wool. This study shows that the discriminating ability of Raman spectroscopy depends on the fiber type, color, and the laser wavelength.

Published: October 2013

AbstractAimPreterm children are at risk of developing increased blood pressure (BP). We evaluated possible associations between BP, early insulin‐like growth factor‐1 (IGF‐1) and IGF‐binding protein‐1 (IGFBP‐1) levels and retinopathy of prematurity (ROP) in preterm children.MethodsThe study included 32 infants: median gestational age 28.1 weeks (range 24.6–31.3) and birthweight standard deviation scores (SDS) (±SD) 1.0 ± 2.7. IGF‐1 and IGFBP‐1 at postnatal weeks 32.6–34.6 and ROP stages were established after birth. BP was measured at the age of 4 years. The ratio (IGF‐1)2/IGFBP‐1 was created to investigate the influence of both IGF‐1 and IGFBP‐1 to later BP.ResultsDiastolic BP correlated with IGFBP‐1, inversely correlated with IGF‐1 and IGF‐12/IGFBP‐1 (r = −0.71, p < 0.0001) and positively correlated with catch‐up growth velocity from lowest weight SDS to age 36.5 weeks (r = 0.48, p < 0.01), independent of gestational age. Children with moderate‐to‐severe ROP as neonates had higher mean arterial BP [78 (±95%CI 74–83) vs 71 (±95%CI 68–75) mm Hg, p < 0.05] adjusted for gestational age and birthweight SDS compared to children diagnosed with no to mild ROP.ConclusionLow neonatal IGF‐12/IGFBP‐1 and severe ROP were associated with higher BP in 4‐year‐old children born very preterm and may thus predict future cardiovascular morbidity.
Mitochondrial dysfunction in amyotrophic lateral sclerosis – a valid pharmacological target?
Authors: Muyderman H , Chen T 
Published: October 2013

Amyotrophic lateral sclerosis (ALS) is an adult‐onset neurodegenerative disease characterized by the selective death of upper and lower motor neurons which ultimately leads to paralysis and ultimately death. Pathological changes in ALS are closely associated with pronounced and progressive changes in mitochondrial morphology, bioenergetics and calcium homeostasis. Converging evidence suggests that impaired mitochondrial function could be pivotal in the rapid neurodegeneration of this condition. In this review, we provide an update of recent advances in understanding mitochondrial biology in the pathogenesis of ALS and highlight the therapeutic value of pharmacologically targeting mitochondrial biology to slow disease progression.Linked ArticlesThis article is part of a themed issue on Mitochondrial Pharmacology: Energy, Injury & Beyond.

Published: October 2013

SummaryBackgroundSevere asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory airway diseases in which the mechanisms are not fully understood. A disintegrin and metalloproteinase domain 8 (ADAM8) is an enzyme expressed on most leucocytes and may be important for facilitating leucocyte migration in respiratory disease.ObjectiveTo investigate ADAM8 mRNA and protein expression in asthma and COPD and its relationship between asthma severity and inflammatory phenotypes.MethodsInduced sputum was collected from 113 subjects with asthma (severe n = 31, uncontrolled n = 39 and controlled n = 35), 20 subjects with COPD and 21 healthy controls. Sputum ADAM8 mRNA expression was measured by qPCR, and soluble ADAM8 (sADAM8) protein was measured in the sputum supernatant by validated ELISA.ResultsADAM8 mRNA correlated with ADAM8 protein levels (r = 0.27, P < 0.01). ADAM8 mRNA (P = 0.004) and sADAM8 protein (P = 0.014) levels were significantly higher in both asthma and COPD compared with healthy controls. ADAM8 mRNA (P = 0.035) and sADAM8 protein (P = 0.002) levels were significantly higher in severe asthma compared with controlled asthma. Total inflammatory cell count (P < 0.01) and neutrophils (P < 0.01) were also elevated in severe asthmatic sputum. Although ADAM8 mRNA was significantly higher in eosinophilic and neutrophilic asthma (P < 0.001), sADAM8 did not differ between asthma inflammatory phenotypes. ADAM8 expression positively correlated with sputum total cell count and sputum neutrophils.Conclusions and Clinical RelevanceADAM8 expression is increased in both severe asthma and COPD and associated with sputum total cell count and neutrophils. ADAM8 may facilitate neutrophil migration to the airways in severe asthma and COPD.

Published: October 2013

AbstractObjectiveTo compare implant stability throughout osseointegration, peri‐implant marginal bone loss, and success rates of implants placed with conventional and mixed drilling/piezoelectric osteotomy.Materials and methodsA pilot randomized‐controlled trial was performed on 15 patients. Each patient received two implants in the mandibular molar region. All sites were prepared with conventionally up to the 2.8 mm wide drill. Osteotomies were randomly finalized with a 3 mm diameter drill (control group) or with two consecutive ultrasonic tips (2.8 mm and 3 mm wide, respectively) (test group). Resonance frequency analysis measurements were taken at implant placement and after 1, 3, 8, and 12 weeks. Peri‐implant marginal bone loss 12 months after loading was calculated using periapical radiographs. Wilcoxon test for related samples was used to study differences in implant stability and in peri‐implant marginal bone loss between the two groups.ResultsTwenty‐nine of 30 implants osseointegrated successfully (one failure in the control group). Stability was significantly higher in the test group at the 8th week assessment; differences were non‐significant at all other time‐points. Longitudinally, differences were observed between the patterns of implant stability changes: in the test group stability increased more progressively, while in the control group an abrupt change occurred between the 8th and 12th weeks assessments. No difference was found in peri‐implant marginal bone loss between the groups. All 29 implants were functionally successful at the 15‐month visit.ConclusionsWithin the limit of this pilot study (small sample size, short follow‐up), data suggested that implant stability might develop slightly faster when implant site osteotomy is performed with a mixed drilling/ultrasonic technique.
Factors influencing egg parasitism in sub‐social insects: insights from the treehopper Alchisme grossa (Hemiptera, Auchenorrhyncha, Membracidae)
Authors: CAMACHO LUIS , KEIL CLIFFORD , DANGLES OLIVIER 
Published: October 2013

Subsocial insects rely on maternal care in order to enhance offspring survival. Subsocial Hoplophorionini treehoppers defend their egg masses from predatory and parasitoid attacks. Egg parasitic wasps are important enemies of the Membracidae.
We examined parasitism patterns and female defence mechanisms in the Hoplophorionini treehopper Alchisme grossa (Fairmaire). We examined the effect of aggregations of egg‐guarding females, spatial aggregations of host plants and female A. grossa, and host plant identity on the incidence of egg mass parasitism. Additionally, we measured the effect of female maternal care strategies on reducing the amount of parasitism on their egg masses.
Aggregation of egg‐guarding females on a single host plant was the most important factor affecting egg mass parasitism. Increased numbers of aggregated females lowered both parasitism risk and parasitism levels on their egg masses. When spatial clumping of host plants and egg‐guarding females occurred simultaneously, parasitism risk was also reduced. Maternal care strategies such as coverage of the egg mass by the females' pronota and intensity of female defensive behaviour also seemed to lower parasitism on egg masses.
A reduction of parasitism by female aggregation on host plants can be explained by a selfish herd dilution effect. This dilution effect was potentiated by a possible cooperation between aggregated egg‐guarding females on the host plant. The present study provides a new dimension to sub‐sociality in Hoplophorionini treehoppers.
