CONSUMERS ’ UNDERSTANDING AND USE OF TEXTILE ECO-LABELS DURING PRE-PURCHASE DECISION MAKING

Eko-etikette het ʼn groot impak op die waarskynlikheid dat verbruikers omgewingsvriendelike produkte sal koop en dit is ʼn hulpmiddel om beter ingeligte aankoopbesluite gedurende hulle besluitnemingsproses te neem. Die tekstielindustrie is verantwoordelik vir ʼn groot hoeveelheid besoedeling, maar het begin om ʼn meer holistiese, omgewingsvriendelike benadering te volg. Inligting rakende tekstiele se eko-vriendelike eienskappe word aan verbruikers gekommunikeer deur middel van eko-etikette. Deur aan te dring op ekotekstielprodukte kan verbruikers die tekstielindustrie beïnvloed om meer produkte met eko-etikette in hul tekstielreekse in te sluit. Internasionale studies toon egter aan dat verbruikers nie tekstiel-eko-etikette of die inligting daarop verstaan nie. ʼn Gebrek aan begrip verhoed hulle om omgewingsvriendelike produkte in die aankoopbesluitnemingsproses in te sluit. Daar is wel verbruikers in ontwikkelde en ontwikkelende lande wat eko-etiketprodukte aankoop en bereid is om meer daarvoor te betaal. Daar is egter beperkte navorsing op die gebied, veral in ʼn Suid Afrikaanse konteks, wat dus meer navorsing in hierdie studieveld genoodsaak het. Daarom het hierdie studie dit ten doel gestel om verbruikers se begrip en gebruik van tekstiel-eko-etikette tydens die aankoopverbruikerbesluitnemingsproses te verken.
Implied Market Loss Given Default: structural-model approach

This paper focuses on the key credit risk parameter–Loss Given Default (LGD). We describe its general properties and determinants with respect to seniority of debt, characteristics of debtors or macroeconomic conditions. Further, we illustrate how the LGD can be extracted from market observable information with help of the adjusted Mertonian structural approach. We present a derivation of the formula for expected LGD and show its sensitivity analysis with respect to other structural parameters of the company. Finally, we estimate the 5-year expected LGDs for companies listed on Prague Stock Exchange and find out, that the average LGD for this analyzed sample is around 20%. To the author’s best knowledge, those are the first implied market estimates of LGD in the Czech Republic.
Study of anatomical changes of bread wheat (Triticumaestivum.L) due to different saline conditions

Present study focused on the response of two different varieties of wheat (Triticum aestivum. L) against salinity. Salinity treatments were made by measuring half the amount of NaCl ds m−1 needed to be prepared in distilled water. Anatomical alterations were seen in all treatments and the alterations increased as saline concentration increased. However, both the varieties managed to survive and bring about changes in stem, root and leaf. The anatomical features of both the varieties were observed under microscope and photographs were taken.
GENETIC VARIABILITY OF THE TOMATO LEAF MINER (Tuta absoluta MEYRICK; LEPIDOPTERA: GELECHIIDAE), IN TUNISIA, INFERRED FROM RAPD-PCR

El minador de hojas de tomate Tuta absoluta Meyrick ha invadido el cultivo del tomate (Solanum lycopersicum L.) en Tunez desde 2008 y actualmente representa una importante amenaza para su produccion. En este estudio usamos la tecnologia de ADN polimorfico amplificado al azar-reaccion de cadena polimerasa (RAPD-PCR) para evaluar la variabilidad genetica dentro y entre siete poblaciones de T. absoluta, colectadas desde tomate en diferentes regiones de Tunez. Usando cinco primers RAPD-PCR y 108 individuos, se registraron 140 fragmentos polimorficos. Se generaron 335 fenotipos RAPD diferentes, entre los cuales 71 fueron redundantes y 264 unicos para una poblacion especifica. La estructura genetica de T. absoluta se investigo usando analisis de varianza molecular (AMOVA), distancias geneticas (Fst) y escalamiento multidimensional (MDS). Detectamos una alta diversidad genetica dentro y entre poblaciones en conjunto con una diferenciacion significativa entre poblaciones, sugiriendo que los genotipos fundadores podrian haber sido responsables de la introduccion de T. absoluta en Tunez. La presencia de fenotipos superpuestos probablemente indica eventos de migracion entre poblaciones, principalmente a traves de material vegetal infestado transportado por humanos.
Synthesis of geranylhydroquinone derivatives with potencial cytotoxic activity

Natural geranylhydroquinone 1 and geranyl-p-methoxyphenol 2 were prepared by Electrophilic Aromatic Substitution (EAS) reactions between geraniol and 1,4-hydroquinone or p-methoxyphenol respectively, using BF3∙Et2O as a catalyst. Furthermore, natural geranylquinone 3, geranyl-1,4-dimethoxyquinone 4 and the new geranyl-4-methoxyphenyl acetate 5 were obtained by chemical transformations of 1 and 2. The compounds were evaluated for their in vitro cytotoxicity activities against cultured human cancer cells of PC-3 human prostate cancer, MCF-7 and MDA-MB-231 breast carcinoma, and Dermal Human Fibroblasts DHF. IC50 values were in the µM range.
Impact of board structure on firm performance: Evidence from an emerging economy

Purpose The aim of this paper is to examine the association between board demographics and firm financial performance of Karachi Stock Exchange companies and describe the attributes of these firms and their boards. The connection between board structure and firm performance has attracted much attention, especially in emerging economies, yet yielded many inconsistent empirical results. Design/methodology/approach This study examines the relationship between board structure and the performance of Pakistani public listed companies by using a sample of Karachi Stock Exchange 100 (KSE-100) indexed companies. This study exploits the corporate performance by accounting-based measures (return on assets), market-based measures (Tobin’s Q), and economic profit (economic value added). Findings The outcome of the study shows the positive relationship between the board size, minority representation in board, and family director’s in-board and firm performance. The authors also find that, instead of adding value, independent directors in Pakistan are negatively associated with firm value. Research limitations/implications The study is based on KSE-100 indexed companies from 2009 to 2013; however, a large sample and multiple years’ data are required. Practical implications The paper provides empirical evidence that board independence is not necessary for public-listed companies in Pakistan and would be of interest to regulatory bodies, business practitioners, and academic researchers. Originality/value The paper contributes to the literature on corporate governance and firm performance by introducing a framework for identifying and analyzing moderating variables that affect the relationship between board structure and firm performance.
Evaluation of the biological activity of crude latex and ethanolic leaves extract of Calotropis procera (Asclepiadaceae) against the mosquito vector Culex quinquefasciatus (Diptera: Culicidae)

In recent years, use of environmentally friendly and biodegradable natural insecticides of plant origin have received a great attention as agents for disease vector control. Crude latex and ethanolic extract of leaves from the Saudi plant Calotropis procera (Asclepiadaceae) were tested against 3rd instar larvae of Culex quinquefasciatus mosquito. The obtained results indicated that crude latex was more efficient than ethanolic leaves extract. The LC50 values of the crude latex and ethanolic leaves extract were found to be 57.3 and 388.7 ppm, respectively. Also, a remarkable reduction in both the pupation percent and adult emergence was obtained. Moreover, the latex showed a highly delayed toxic effect on the pupae and adults resulted from treated larvae, where the pupal mortality was 100% at the highest concentrations used (75 and 150ppm). The current results were considered promising to proceed in studying the bioactive plants which represent an environmentally sound alternative for the synthetic larvicides.
Microbiological Profile and Antibiogram of Blood Stream Isolates at a Referral Hospital in North Delhi: A One Year Study

Introduction: Blood culture is the gold standard for diagnosis of bacteremia. It identifies the pathogen and allows susceptibility testing. Objective: To identify Blood stream infections (BSI) which are critical and may prove fatal if not treated promptly. Material and Methods: This was a retrospective study done at our institution to identify the prevalent microbial agents causing infections in hospitalized patients. A total of 1521 blood cultures were processed. Antimicrobial susceptibility was performed for clinically significant isolates. Results: Of total cultures, 16.1% were positive for bacterial growth and 3.1%for fungal growth. Conclusion: Local microbiological profile with antibiogram of frequently isolated organisms should be known to limit the severity of disease and initiate empiric treatment for blood stream infections.
VALIDITY OF THE TECHNOLOGY ACCEPTANCE MODEL (TAM): A SENSEMAKING PERSPECTIVE

This study investigates whether sensemaking activities influence technology acceptance and if the strength of relationship between TAM’s constructs changes over a period of time. This study was a panel-based longitudinal study, whereby data was collected in three stages within a single semester. The setting of the study was at the School of Management, USM. The major findings of the study showed that sensemaking does influence the TAM if activities are undertaken at high and low levels and also sensemaking influences individual constructs of TAM rather than the whole model. This study failed to prove that there is a significant change in the strength of relationship between TAM constructs over a period of time under sensemaking influence, which is that sensemaking activities were found not to exhibit any moderation effect on the TAM constructs. Sensemaking acts as an external variable which influences TAM rather than moderate the strength of the relationship between TAM constructs. This could be because the technology in question was mandatory to be used by the subjects rather than voluntary. Implications for managers are discussed.
The physical activity and mental health relationship - a contemporary perspective from qualitative research

There is a known positive relationship between physical activity and mental health, and in the treatment and maintenance of mental illness. Despite this relationship however, there still remains a lack of consensus on the mechanism responsible for the relationship. This paper explores the physical activity and mental health relationship by reviewing and critiquing the biochemical, physiological and psychological mechanisms proposed to explain this phenomenon. Through this review it becomes apparent that although there are varied explanations proposed, there is little agreement except that the relationship is complex and the responsible mechanism(s) are likely to be interrelated combining the disciplines of psychology, biochemistry and physiology. In an attempt to understand further the complexities of the relationship the paper presents findings from qualitative research that investigated the relationship from the perspectives of people that experience mental health benefits from exercise. Using grounded theory methodology the study investigated the experiences of participants on exercise programmes in the UK. The paper concludes that qualitative methodologies which explore people experiences, and what helps to facilitate them, provide further insight into the interrelated nature of the physical activity and mental health relationship.
Are mobile researchers more productive and cited than non-mobile researchers? A large-scale study of Norwegian scientists

The scientific performance of mobile and non-mobile researchers is analysed using publication and citation indicators in a study of more than 11,000 Norwegian university researchers. Two types of mobility are investigated: change of work place during the scientific career and mobility from an academic institution granting the highest degree to another work place for the scientific career. The study shows that mobile researchers tend to have slightly higher publication and citation rates than other researchers, but the results are not unambiguous.
Fish community in a surf zone of the northern Sicilian coast (Mediterranean Sea): diversity and functional guild composition

Fish assemblage in a surf zone of the southern Tyrrhenian Sea was investigated for the first time. Samples were collected during four surveys by a modified beach-seine, from June 2005 to May 2006. Overall, 42 species belonging to 19 families were recorded. Among them, Sardina pilchardus showed the highest abundance values, while Mugilids ( Oedalechilus labeo and Liza aurata ) were the most frequently caught species. The fish community was dominated by pelagic and gregarious species using this habitat as a foraging ground and recruitment area. Juveniles and early adults made up the largest proportion of the ichthyofauna. Fishes inhabiting the surf zone were mainly strictly benthic invertebrate feeders and invertivorous/piscivorous fish; strictly planktivorous were represented by few species but strongly dominant in terms of catch per unit effort; strictly piscivorous fish were poorly represented. Fish composition varied over the study period with the greatest abundance in May and December, and the highest richness and diversity in October.
Asylum Seekers in the News: Frames of Illegality and Control

Since the early 1990s migration policies in Europe have thematically shifted from human-rights issues to control policies. Distinguishing political refugees from economic migrants has become more difficult. Analyses of this shift cannot overlook the role of journalism. By setting the agenda news journalism defines what is discussed and by framing the issues it selects how these issues are discussed. This article uses frame analysis for foreign and domestic news of asylum seeking in the National Finnish News Agency (STT). The data consists of news published in 2002, total of 237 news items. Two frames are the most dominant. Firstly, the news are more often linked with trans-national crime and clandestine travel than with humanitarian issues. The illegality frame links foreign news with domestic news. Small incidents of ‘illegal immigration’ in Finland are covered since ‘illegality’ is on the agenda through news flows from other countries. Asylum seeking is presented as a common European problem. Additionally, the news construct a frame of controlled immigration in Finland. Often, insignificant details are reported which produce a panoptic eye on asylum seekers: they are being watched, moved and removed. The news construct a panopticon over asylum seekers.
The Time Gap between Repeated Re-Happening Opportunistic Infections among People Living with HIV/AIDS Commencing Antiretroviral Treatment

Introduction: According to 2011 Ethiopian demographic health survey, the national and Amhara Regional state administration adult HIV prevalence was 1.5 % and 2.2% respectively. The major causes of morbidity and mortality of PLWHA (people living with HIV/AIDS) patients are OIs (opportunistic infections) that would occur in up to 40% of PLWHA. OIs are repeatedly happening in HIV (Human Immunodeficiency Virus) infected patients though there is no prior local evidence on time gap of repetition. Therefore the current study is aimed to determine time gap between repeated re-happening OIs and its associated factors among PLWHA who are initiated ART (Anti-Retroviral Treatment). Method: Institution based retrospective cohort study was conducted among 364 systematically selected PLWHA commencing ART. Time-gap was estimated using Kaplan-meier survival and actuarial life table. Hazard rate was calculated using Cox proportional-hazard model. Result: during follow up OIs were re-diagnosed in about three quarter (76.9%) of participants. In each week the probability of getting the re-happened OI was 1.1 per 100 persons. The median duration of staying free of OI re-happening was 66 weeks. In multivariate analysis using logistic regression, educational status, marital status, Prophylaxisis exposure, ART and Prophylaxisis drug adherence, hemoglobin and CD4 level were significantly associated with time gap of relapse. Thus organizations working on HIV/AIDS should further work to enhance time gap of relapse.
Analyzing the Influence of Neighborhood Development Pattern on Modal Choice

Although several studies have been undertaken on the association between built environmental characteristics and travel patterns in western societies, the impacts of the local built environment on individuals’ travel behavior considering the specific conditions of developing nations have remained largely unknown. Thus, this paper investigates the travel behavior effects of local planning and design in three residential neighborhoods of Shiraz, a city in the southwest of Iran. The data on land use and built environment characteristics were extracted primarily from an existing digital map and GIS, whereas the data on individuals’ socioeconomics and their daily travel behavior were purposefully collected using a field questionnaire survey (). A nested logit model (NLM) based on the microeconomic utility concept was then applied to discover the impacts of personal characteristics and built environment factors on the choice mode of the individuals. The results and the associated policy implications can be helpful in defining a strategic agenda for neighborhood design and planning.
Photosynthesis, Resource Acquisition and Growth Responses of Two Biomass Crops Subjected to Water Stress

This study compares photosynthesis, growth, 13C and 15N labelling patterns of two biomass crops (Arundo donax L. and Panicum virgatum L.) grown under water stress in greenhouse conditions. Plants were exposed to three water stress levels: control (C, 100% Pot Capacity), mild stress (MS, 50% PC) and severe stress (SS, 25% PC). Photosynthesis, fluorescence parameters and relative water content were measured at the beginning (Ti) and the end of the experiment (Tf). Biomass parameters were measured at Tf. Short-term double labelling with 13C and 15N stable isotopes was performed in both species. Isotopic analyses of total organic matter, total soluble sugars and the CO2 respired were undertaken at T0 (pre-labelling), T1 (24h after labelling) and T2 (7 days after labelling). Immediately after the 13C and 15N labelling, stems and rhizomes seemed to be the main sinks for labelled carbon and nitrogen in both species. Moreover, not all of the labelled carbon and nitrogen substrate was used by plant metabolism after seven days. Decreases in photosynthesis parameters were observed as a consequence of the increase in water stress (WS) in both species, with a greater magnitude decline in giant reed than in switchgrass. A decrease in height, number of green leaves and total dry weight due to WS was observed in both species. Both species were more 13C-enriched and more 15N-depleted during the increases in WS due to lower stomatal conductance and transpiration. In general, WS accelerated plant phenology and, consequently, the accumulation of storage compounds in the rhizome occurred in response to stress. This effect was more clearly visible in switchgrass than in giant reed.
On The Possibility to Trace Frozen Curd in Buffalo Mozzarella Cheese

The manufacturing of Buffalo Mozzarella PDO (Protected Designation of Origin) cheese requires the exclusive use of fresh buffalo milk, which must be transformed into cheese within 60 hours after milking. The limited availability of buffalo milk and simultaneous increase in Mozzarella demand during the summer cause producers to use frozen intermediates (milk and/or curd) in the cheese-making process. These practices are not allowed. Few data are available in the literature about the effects of freezing on buffalo milk and curd. Recent studies demonstrated that the use of frozen buffalo milk can be detected in mozzarella cheese based on the increase in casein fragment γ4-CN. This work aims to verify the possibility of tracing the presence of frozen curd in Buffalo Mozzarella PDO cheese. The electrophoresis technique was used to reveal the presence of γ4-CN. Equivalent concentrations of this fragment were found in fresh and frozen curd that were stored for 9 months. Our results suggest that γ4-CN cannot be used to discriminate fresh PDO Mozzarella and Mozzarella cheese produced from frozen curd. A second objective of the work was to evaluate the effects of freezing on curd lipids. In particular, the fatty acid and mono-diglyceride profiles were evaluated. Significant differences were found in the amounts of 1,2-Dipalmitin and 1,3-Diolein between fresh curd and curd that was stored for 9 months at freezing temperatures. Although some significant differences were found in the mono-diglyceride profiles, no objective marker that can distinguish between fresh and frozen products is currently available.
OBSERVATIONAL CONSTRAINTS ON FIRST-STAR NUCLEOSYNTHESIS. II. SPECTROSCOPY OF AN ULTRA METAL-POOR CEMP-no STAR

We report on the first high-resolution spectroscopic analysis of HE 0020–1741, a bright (V = 12.9), ultra metal-poor ( = −4.1), carbon-enhanced ( = +1.7) star selected from the Hamburg/ESO Survey. This star exhibits low abundances of neutron-capture elements ( = −1.1) and an absolute carbon abundance A(C) = 6.1; based on either criterion, HE 0020–1741 is subclassified as a carbon-enhanced metal-poor star without enhancements in neutron-capture elements (CEMP-no). We show that the light-element abundance pattern of HE 0020–1741 is consistent with predicted yields from a massive (M = ), primordial-composition, supernova (SN) progenitor. We also compare the abundance patterns of other ultra metal-poor stars from the literature with available measures of C, N, Na, Mg, and Fe abundances with an extensive grid of SN models (covering the mass range ), in order to probe the nature of their likely stellar progenitors. Our results suggest that at least two classes of progenitors are required at , as the abundance patterns for more than half of the sample studied in this work (7 out of 12 stars) cannot be easily reproduced by the predicted yields.
MeV dark matter complementarity and the dark photon portal

We discuss the phenomenology of an MeV-scale Dirac fermion coupled to the Standard Model through a dark photon with kinetic mixing with the electromagnetic field. We compute the dark matter relic density and explore the interplay of direct detection and accelerator searches for dark photons. We show that precise measurements of the temperature and polarization power spectra of the Cosmic Microwave Background Radiation lead to stringent constraints, leaving a small window for the thermal production of this MeV dark matter candidate. The forthcoming MeV gamma-ray telescope e-ASTROGAM will offer important and complementary opportunities to discover dark matter particles with masses below ∼ 10 MeV . Lastly, we discuss how a late-time inflation episode and freeze-in production could conspire to yield the correct relic density while being consistent with existing and future constraints.
Mechanical Properties of Mg–Al–Ca Alloy Recycled by Solid–State Recycling

Solid-state recycling for runner scraps of Mg-Al-Ca alloy was carried out by extrusion at 673 K and mechanical properties of the recycled Mg alloy were investigated by tensile tests. At room temperature, the recycled specimen showed a good combination of high ultimate tensile strength (348 MPa), high 0.2% proof stress (305 MPa) and large elongation (9%). Additionally, the recycled specimen exhibited superplastic behavior at 573 and 673 K. The excellent mechanical properties of the recycled specimen result most likely from fine dispersion of precipitates which is attained by hot extrusion.
