Testing a Warmth-Based Instruction Intervention for Reducing Library Anxiety in First-Year Undergraduate Students
Authors: Parks Cecelia
Published: June 2019

Abstract

Objective – This study aimed to test the efficacy of a warmth-based library instruction intervention in reducing rates of library anxiety in first-year undergraduate students. "Warmth" is a concept that is commonly discussed within literature on library anxiety, but to date no studies have explicitly tested the application of a warmth-based instruction intervention. First-year students are ideal targets for this intervention because they are the most likely to experience library anxiety.

Methods – A quasi-experiment was conducted examining library anxiety rates in first-year undergraduate students at a public research university in the U.S. South. A one-shot warmth-based instruction session focusing on the emotional dimensions of library use was compared to a standard one-shot instruction session. Library anxiety was measured using a modified version of Bostick's Library Anxiety Scale as a pretest and posttest.

Results – Results indicated that both warmth-based and standard library instruction were associated with a decrease in participants' library anxiety rates without significant differences between the types of instruction. However, warmth-based instruction was correlated with greater reductions in areas of library anxiety related to interactions with library workers. Though library anxiety rates decreased significantly after experiencing library instruction, participants exhibited low levels of library anxiety before their library instruction session occurred.

Conclusion – Though warmth-based instruction did not have a significantly different impact than standard library instruction on general library anxiety, the intervention tested in this study suggests strategies that could be used to increase student comfort with library workers. This study also demonstrates a successful method to include emotional factors such as library anxiety in academic libraries' regular assessment programs. Focusing assessment on students' skills and knowledge alone risks ignoring an important aspect of student engagement and missing opportunities for academic libraries to connect with students. Assessment of emotional components of library instruction initiatives is especially crucial to ensure and demonstrate that libraries are using their resources effectively to maximize student success.
Green Deposit Rates in LIS Taylor & Francis Journals: Are Librarians “Practicing What They Preach?”
Authors: Koos Jessica A.
Published: June 2019

A Review of:

Emery, J. (2017). How green is our valley: Five year study of selected LIS journals from Taylor & Francis for green open access. Insights, 31(23). http://doi.org/10.1629/uksg.406

Abstract

Objective – To investigate the green deposit rate for articles published in five Taylor & Francis LIS journals.

Design – Content analysis.

Setting – The author conducted an analysis of the following journals: Behavioral & Social Sciences Librarian, Collection Management, College & Undergraduate Libraries, Journal of Electronic Resources Librarianship and Journal of Library Administration. 

Subjects – 87 articles/columns in Behavioral & Social Sciences Librarian, 78 in Collection Management, 134 in College & Undergraduate Libraries, 108 in Journal of Electronic Resources Librarianship, and 264 in Journal of Library Administration. 

Methods – The author chose five Taylor & Francis LIS journals to analyze over a period of five years for the green open access article deposit rate. The author selected Taylor & Francis journals due to the publisher’s policy of not requiring an embargo period on LIS journals. The specific journal titles were selected based on the author’s perception of their relevance to a broad array of academic libraries. The author determined if green deposit had occurred by first using the “OA Button” on the article’s homepage to locate the full text. If nothing was found, the author then searched each author’s institutional repository using the DOI. If the full text was still not located using this method, then a Google Scholar search for the full text was performed.

Main Results – The author found that the full text was available for 22% of the 671 total articles included in the study, which was significantly below the author’s proposed success rate of 50%.

Conclusion – The results of this study indicate that a relatively low number of articles in the LIS field are available via open access, even though there were no restrictions from the publisher on green deposits. Some potential influencing factors for the low deposit rate include lack of encouragement from administration on utilizing repositories, imposter syndrome, and a lack of awareness of Taylor & Francis’s green deposit policies. The author recommends that librarians and their administrators support and encourage one another to make articles available via open access. The author also recommends that Taylor & Francis further publicize this policy to make more authors aware of it.

Authors: Tandon Praveen Kumar , Chaurasia Girdhari Lal
Published: June 2019

Water, the Nectar of Life’, is fundamental resource which is essential for the survival of different sectors, such as agricultural sector, industrial sector and small business units. In the absence of proper planning, urbanization and industrial/agricultural activities have adversely affected many regions around the world. This has led to indiscriminate actions, including dumping of wastes into the water and washing and bathing in open surface water bodies. In the present study groundwater samples from five sampling locations were collected and the analyses were done for nine physicochemical parameters. Water quality index assessment was carried out by using physicochemical analysis results. Water quality index of the sampling locations of Allahabad city has been divided into five categories. Good water quality index has been put into location 1 while locations 2, 3 and 4 indicate bad quality index. Very bad water quality index has been denoted in location 5. Correlation, the descriptive relationship among the physicochemical parameters, were also studied and it was found that the highly positively correlated values were among the parameters TDS vs EC (r=1.00), TS vs TSS (r=0.91), Temp vs TSS (r=0.87), Phosphate vs TSS (r=0.823) and highly negatively correlation was shown among TA vs Chloride. The result shows that the water quality of Allahabad city is not good and there is an urgent need for the preliminary treatment of water before it is used for the drinking purposes. There is also the need for the proper waste disposal and treatment system for the contaminants which seep in the groundwater and deteriorate groundwater quality. Awareness programmes should also be organized to educate the masses for the conservation and management of groundwater resources and the need to reduce of overuse and wastage of the groundwater resources should be emphasized. Sustainable water development in the city is needed to fulfill the demand of water for future.
BINDING OF RUTHENIUM(II)POLYPYRIDYL COMPLEXES WITH POLYPHENOLS IN AQUEOUS MEDIUM
Authors: Raj G.Allen Gnana
Published: June 2019

The binding of three Ru(II)-polypyridyl complexes with polyphenols (gallic acid and quercetin) have been studied in aqueous medium at pH 11 by means of absorption spectral technique. The absorption and emission maximum of this complexes are in the range of 451-457 nm and 612-626 nm respectively. The binding constant (Kb) for these reactions are determined from the Benesi-Hildebrand equation using absorption intensity data.The observed binding constant values are sensitive to the nature of the ligand and the structure of the gallic acid and quercetin. Quercetin binds strongly with Ru(II) complexes than gallic acid owing to the presence of more phenolic –OH groups. Structural effect seems to play a vital role on the binding of the antioxidants with these complexes.
MANAGING FORMER LANDFILL SITES A CASE STUDY OF ECORESTORATION FROM KOCHI, KERALA
Authors: Chandran Smitha
Published: June 2019

This paper describes the dramatic success in the eco-restoration of a heavy-metal contaminated open garbage dump at the Amrita Institute of Medical Sciences (AIMS), a 1450-bed super-specialty hospital located in Kochi, Kerala, India. Today, the hospital caters to over 10 lakh patients annually. Inspired by our Chancellor’s vision of zero-waste, the hospital undertook its journey with a view to also reducing massive greenhouse gas emissions that result from improper handling of waste. Today, the hospital manages its municipal solid waste on an industrial scale, composting some eight metric tonnes of organic waste daily.

This case study outlines the path followed to achieve zero-waste. Alongside, the rehabilitation of a former dump site is described in detail at this very site are carried out all composting operations of AIMS. Within three years of the restoration activities, heavy metal concentrations in the contaminated soil reduced drastically.

There was relatively low uptake of the heavy metals by the plants; however, they might have been crucially responsible for providing a favorable environment for soil restoring microorganisms in their rhizosphere. Observable habitat-restoration continues at the site, including the return of birds and insects and other wildlife, making this an ideal site for further research and demonstration for community awareness and education.
SYNTHESIS AND CHARACTERIZATION OF ORGANICALLY MODIFIED GD2O3 - NATURAL RUBBER COMPOSITES AS EFFECTIVE X-RAY SHIELDING MATERIALS
Authors: Sambhudevana Sreedha
Published: June 2019

Protective materials based on lead are the usual X- ray shielding materials but their extended use leads to severe health problems due to the toxic nature of lead. Moreover, lead based materials are not appropriate for absorbing the regular energy region of X-ray used in medical field and hence natural rubber composites containing modified Gadolinium oxide (Gd2O3) as filler is suggested as an alternative. Natural rubber composites were prepared with organically modified Gd2O3 at various filler loadings.The structural features of modified Gd2O3 were examined using FTIR, X-ray diffraction and SEM. The particle size of organically modified Gd2O3 was found to be in the nano range which contributes to the enhanced properties of the composites. The increase of filler loading improved the shielding effectiveness of the rubber composites. Examination of mechanical and X-ray shielding properties show the effectiveness of the material to be used as potential shielding materials.

Authors: Tandon Praveen Kumar , Shukla Neelam
Published: June 2019

Presence of microscopic algae can cause taste and odour problems, water discoloration, or form large mats that can interfere with boating, swimming, and fishing. The present study was conducted to assess the phytoplankton assemblages which in turn can serve as a suitable method to assess the quality of river ecosystem. Diversity of phytoplankton in river Ganga in Allahabad at five sampling stations was conducted from March to April 2014. Plankton identified in the river mainly composed of the members of Bacillariophyceae, Chlorophyceae and Cyanophyceae families. The Palmer pollution index values were calculated to know the level of organic pollution and to support the data. On the basis of quantitative and qualitative estimates 15 significant algal species were identified which can tolerate high degree of pollution. The abundance of phytoplanktons in april was greater than in march. Abundance of phytoplanktons and algal bloom was maximum at Chhatnag ghat whereas at Sangam low phytoplankton diversity was found. In general, moderate temperature, low current velocity and high transparency of water appear to be better the conditions for algal growth in the river Ganga. These findings highlighted the deterioration of water quality of the river due to industrial, commercial and anthropogenic activities. The status of phytoplankton diversity of river Ganga was quite low indicating that the river is highly polluted.

COMPARATIVE ANALYSIS OF SOME MINERAL PROFILE OF HONEY MARKETED AND CONSUMED IN SOME OF THE STATES IN NORTHERN PART OF COUNTRY (NIGERIA)
Authors: Odoh R.
Published: June 2019

Honey and honey trade is an important economic activity for many tropical rural and urban areas worldwide. In West Africa and other part of the world, honey and honey products holds high socio–cultural, religious, medicinal and traditional values. Therefore, to maximize benefits or to enhance profit, a variety of components are added to the raw, fresh and unprocessed honey, introducing the possibility of heavy metals contaminants. Therefore the honey sold in various places, markets and shops  in some states in Northern Nigeria (Benue, Nassarawa and Taraba) including Abuja FCT, in Nigeria was analyzed to determine the level of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn). All the honey samples contain heavy metals. The results ranged from 0.028–0.070, 0.023–0.058, 0.042–0.092, 4.231–8.589, 8.115–14.892, 0.078–0.922, 0.044–0.092, 0.041–0.087 and 18.234–28.654 μg/L for Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn respectively. The mean concentration (μg/L) of the heavy metals Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn of the regularly marketed honey is significantly higher than the mean concentration observed in raw, fresh and unprocessed honey. However, continued consumption of honey with high heavy metal content might lead to exposure to chronic heavy metal poisoning.

Published: June 2019

Biomaterials, chemicals and energy from renewable resources have been the object of considerable interest in recent years. Vegetable oils are one of the cheapest and most abundant biological sources available in large quantities and their use as starting materials has numerous advantages such as low toxicity, inherent biodegradability and high purity. They are considered to be one of the most important classes of renewable resources for the production of bio-based thermosets. As a substitute to the use of conventional reinforcing synthetic resins, biobased resins were synthesized from cardanol, renewable and low cost industrial grade oil obtained by vacuum distillation of Cashew Nut Shell Liquid (CNSL), an abundant agricultural byproduct of cashew industry. On the other hand to further expand the field of application, cardanol-based novolac scaffolds, used in the formulation of thermosetting resins by blending with a conventional epoxy resin, especially designed to be compatible with conventional bisphenol- A epoxy resins. In the present study resins have been synthesized by condensing diazotized p-anisidine cardanol dye with urea, resorcinol and furfural as condensing agent.. The resins have been characterised by FT-IR, 1H-NMR and XRD studies. Thermal behavior of the resins has been studied by Thermogravimetric Analysis (TGA) and Differential thermal analysis (DTA). The DTA, SEM and XRD data indicated the percentage of crystallinity associated with the thermal stability of the resins.

Authors: Chmielewská Eva
Published: June 2019

Coagulation/flocculation and ion exchange onto natural zeolite clinoptilolite are reviewed and discussed in this paper based on their pilot or industrial applications. Surface water purification by means of chemical coagulation and flocculation supported by the powdered natural zeolite was carried out industrially to save drinking water reservoir (upper part of Ondava river) settled by about ten thousands inhabitants. Therefore, several other surface water samples from the Slovakian reservoirs potentially impacted by contamination were examined to treat with alum coagulation/flocculation and powdered clinoptilolite tuff addition at the laboratory, respectively. Ammonia removal from tannery wastewater using the clinoptilolite tuff with chemical regeneration and regenerant recovery by air stripping, carried out in pilot measure during the several months at the mixed Wastewater Treatment Facility in Otrokovice - WTFO is discussed and evaluated, respectively.

Authors: Kalita Himani , Pathak Amita
Published: June 2019

The present work reports the preparation of hollow TiO2 nanospheres through sacrificial core templating method where, the sacrificial core of carbon spheres were indigenously synthesized and mixed into the starting ethanolic solution of titanium tetraisopropoxide (TTIP) under ambient condition. The solid obtained on the hydrolysis of TTIP were dried and calcined in air to acquire the hollow nanospheres of TiO2 in anatase phase. The acquired samples were further doped with varying mole % of Mn(II) to invoke magnetism in the material. X-ray diffraction and thermal studies reflected the anatase to rutile phase transformation of TiO2 at 550 °C when the dopant (i.e., Mn) concentration was increased from 0 to 6 mol % (with respect to Ti). The hollow and spherical morphology of the TiO2 nanostructures were confirmed through scanning electron microscopic studies while their ferromagnetic behaviour (at 300 K) was affirmed through SQUID analysis. For intracellular applications, the biocompatibility of the nanospheres was tested through conventional MTT assay, performed on MDA-MB 231 cancer cell lines.

Authors: Patowary Manoj , Pathak Khanindra
Published: June 2019

The present work reports the preparation of super hydrophobic and oleophilic sorbent powder for the selective removal of spilled-oil from oil-polluted water surface. The sorbent powder was prepared by the surface modification of commercially available pure barium sulfate (BS) with palmitic acid via a simple one-step synthetic approach. The powder was observed to exhibit super hydrophobic character with a static water contact angle value of 152±2°. The powder also possesses sufficient buoyancy and exhibits high selectivity towards oil, vital for a sorbent for use in oil spill clean-ups. The oil sorption capacity of the sorbent material was also investigated.
EFFECT OF INCREASING NCO/OH MOLAR RATIO ON THE CHEMICAL AND MECHANICAL PROPERTIES OF ISOCYANATE TERMINATED POLYURETHANE PREPOLYMER DERIVED FROM BIO-MASS
Authors: Rathika K. , David S. Begila
Published: June 2019

The study deals the effect of increasing NCO/OH molar ratio on the physico-mechanical properties of isocyanate terminated polyurethane prepolymer. The prepolymer was prepared using castor oil and toluene-2,4-diisocyanate. The NCO/OH molar ratio has been varied from 1.6 to 2.0. The formation of the prepolymer was confirmed by UV and FTIR spectroscopy. The results reveal that the curing time of the prepolymer decreased with increase in NCO/OH molar ratio. When NCO/OH molar ratio increased, the tensile strength of the polyurethane film increased, while percent elongation decreased due to increase in hard segment content.
