Effects of alcohol drinking of employee on job engagement and interpersonal conflict at work
Authors: Lee Sunhee , Ji Ok Young , Lee Philseok
Published: March 2019

The purpose of the study was to investigate the effects of alcohol drinking of employee on job engagement and interpersonal conflict at work. In order for a better understanding of the effects, we distinguished drinking based on whom they drank with: work-related vs. non-work related. Based on self-control strength theory(Baumeister, Vohs, & Tice, 2007) and effort-recovery model(Meijman & Mulder, 1998), we hypothesized that self-control plays a key role in the process by which work-related drinking influences job engagement and interpersonal conflict. Multi-level analyses on daily survey data from a total of 367 employees for two weeks showed that as participants drank more alcohol with work-related person(s), the level of ego-depletion got worse, and as a result, job engagement faltered. As for interpersonal conflict, the effects of work-related alcohol consumption and ego-depletion varied according to the level of trait self-control. On the other hand, non-work related drinking was positively related to ego-depletion, which was related to only interpersonal but to job engagement. Theoretical and practical implications of the findings and future research directions were discussed.

Published: March 2019

The aim of this study is to depict the
effect of Cooperative Learning (CL) on primary-elementary pre-service teachers’
academic achievement in Turkey in a systematic review. With respect to this
aim, as Turkey adopted Constructivism in education in 2005 which is the major
theory underlying CL, as a time span the search was confined to the literature
between 2005 and 2018. Major search data bases scanned were ULAKBİM, ERIC, Metulib,
MetUnique, J-STOR, Google Scholar, EPÖDER and DergiPark, tezYÖK (national
database for accessing theses). As a
result of this search, based on pre-determined criteria, twelve (13) studies
are included into the review. The themes emerging are as (a) comparison of
cooperative learning (CL) with traditional methods (TMs), (b) comparison of
different methods of CL, (d) Jigsaw as a CL method. As a result of the review,
CL is found to have a significant effect on primary-elementary pre-service
teachers’ academic achievement in Turkey.

Published: March 2019

A two-bed pressure swing adsorption system on a commercial type of zeolite 13X adsorbent has been studied numerically over a wide range of operating conditions to helium separation from gaseous mixture. The model includes energy, mass and momentum balances. The coupled partial differential equations are solved using fully implicit forth order Rung-Kutta scheme in the simulation. The effects of adsorption step pressure, adsorption step time and feed flow rate on the helium purity and recovery were investigated. Results shown that as the adsorption step pressure increases the helium purity will be increased. In addition, the helium recovery increases, and the helium purity decreases when the feed flow rate increases. Finally, the simulation results indicated a very good agreement with some current literature experimentally work.

Published: March 2019

ABSTRACTDifferent periodontal surgical techniques have been proposed for the treatment of periodontal recessions. Among these, the graft of gingival connective tissue stands out for the high predictability of success. This work compared the clinical outcomes of treatment of periodontal recessions, using the gingival connective tissue grafts and acellular dermal matrix. A total of 72 recessions constituted the sample, divided equally into 2 groups. Group 1: treated with acellular dermal matrix graft (MDA) associated with the displaced: Group 2: treated with gingival connective tissue graft, also associated with the flap offset coronally. We evaluated the clinical parameters of probing depth, insert, clinical periodontal recession towards coronal-apical diameter mesio-distal of recessions, keratinized and mucosa thickness flap and influence of grafts in relation to root coverage. The initial measures were compared to those obtained with 45, 90 and 120 days after surgery. No statistically significant differences were found between the groups in terms of reduction of periodontal recessions, keratinized and mucosa flap thickness and of grafts in relation to root coverage. The Group 2 (CG) showed statistically significant reduction in the depth of drilling and clinical level of insertion, compared to group 1 (MDA). However, these differences were not clinically relevant. It was concluded that both the gingival connective tissue graft as the acellular dermal matrix can be used in the treatment of periodontal recessions, with a high predictability of success.Keywords: Gingival recession, connective tissue graft, acellular dermal matrix, periodontal surgery, gum recession, root coverage.

Published: March 2019

The liver is the second largest human organ and has got a complex internal vascular and ductal anatomy. It is subdivided into lobes, sections and segments and receives dual blood supply from the hepatic artery and portal vein. The hepatic veins drain the liver directly into the inferior vena to which the liver is intimately related. Anatomical variations are common. A thorough knowledge of the liver anatomy and its variations is of critical importance for safe and successful procedures and surgeries involving the liver.
The Performance of Stock Portfolios formed using Fuzzy Logic
Authors: Sinha 1 Amit K. , Jacob 2 Andrew J.
Published: March 2019

Expert systems, a type of artificial intelligence that replicate how experts think, can aide unskilled users in making decisions or apply an expert’s thought process to a sample much larger than could be examined by a human expert. In this paper, an expert system that ranks financial securities using fuzzy membership functions is developed and applied to form portfolios. Our results indicate that this approach to form stock portfolios can result in superior returns than the market as measured by the return on the S&P 500. These portfolios may also provide superior risk-adjusted returns when compared to the market.
KSG: indicator of economic concentration
Authors: Meireles Manuel
Published: March 2019

In the fields of Management and Economics, there are many studies that have made use of the degree of concentration of a market or industry, especially when dealing with subjects such as industrial concentration. However, these indexes do not adequately present the level of significance. This problem is overcome by the proposed KSG indicator based on the Kolmogorov-Smirnov test and whose interpretation of significance is given by Goodman. Hence the name: KSG. The proposed model uses non-parametric techniques to establish the dimension of concentration and defines the level of significance of the value found. This is a quantitative study using parametric statistics (polynomial regression) on data generated through simulation. In each data simulation, for the given value of n companies, the share of Company 1 is made to vary, with the other shares being maintained unchanged. For each simulation, data related to values of "Share of Company 1" were extracted and corresponding indexes: KSG, CR4, CR8 and HHI. The results show that the indicator proposed in this study is fully justified.
Column-wise relative degree and it’s properties
Authors: Kraev 1 Andrey Vladimirovich , Rogovskiy 1 A. I.
Published: March 2019

Many questions of control theory are well studied for systems which satisfy to the relative degree definition. If this definition is fulfilled then there exists linear state-space transform reducing system to a very convenient canonical form where zero dynamics is a part of system’s equations. Algorithms of such reduction are well-known. However, there exist systems which don’t satisfy this definition. Such systems are the subject of investigation in the presented paper. To investigate their properties here we suggest to consider an analogue of the classical relative degree definition – the so-called column-wise relative degree. It turned out that this definition is satisfied in some cases when classical relative degree doesn’t exist. We introduce this notion here, investigate it properties and suggest algorithm for reducing systems to the column-wise relative degree compliant form if possible. It is possible to show that systems with column-wise relative degree also can be reduced to a convenient canonical form by a linear state-space transformation. Some problems arise from the fact that some systems which do not have relative degree can be reduced to a form with it using linear inputs or outputs transform. Here we show that this is an interesting mathematical problem, which can be solved with the help of properties of relative degree, formulated and proved in this paper.
A Lattice Boltzmann Scheme for Diffusion Equation in Spherical Coordinate
Authors: Datta Debabrata , Pal T K
Published: March 2019

Lattice Boltzmann models for diffusion equation are generally in Cartesian coordinate system. Very few researchers have attempted to solve diffusion equation in spherical coordinate system. In the lattice Boltzmann based diffusion model in spherical coordinate system extra term, which is due to variation of surface area along radial direction, is modeled as source term. In this study diffusion equation in spherical coordinate system is first converted to diffusion equation which is similar to that in Cartesian coordinate system by using proper variable. The diffusion equation is then solved using standard lattice Boltzmann method. The results obtained for the new variable are again converted to the actual variable. The numerical scheme is verified by comparing the results of the simulation study with analytical solution. A good agreement between the two results is established.

The compound was further characterized by Thin Layer Chromatography (TLC) with the retention value, Rf was found to be in the range of 0.78-0.83 run using a combination of solvent systems water and methanol.  The molecular weight of the compound was found to be 492.2614 g mol-1 identified and analyzed by UHPLC–QTOF-MS analysis. Due to its significant pharmacological importance in proliferative diseases, further studies on production and optimization of these compounds are necessary.
Techniques and methods of seismic data processing in active volcanic areas: some applications to multichannel seismic profiles (Gulf of Naples, Southern Tyrrhenian sea, Italy)
Authors: Gemma Aiello
Published: March 2019

The techniques of seismic surveying, especially reflection seismic, considerably varied during last year’s. The contribution to this variation mainly came from the oil industry, which has developed the geophysical methods for oil searching. The basic techniques of seismic exploration consist of the generation of seismic waves artificially in the ground (source) and of the measurement of the requested times to cover the source-receiver path. Seismic data processing of three multichannel seismic profiles located in the Gulf of Naples for an overall length of 150 kilometers is herein presented. The techniques of seismic processing used for the elaboration of the seismic data are up-to-date. Some of them are based on complex mathematical models, allowing obtaining good velocity analysis for the production of stacked sections, ready to be interpreted. In this paper the procedures of processing of multichannel seismic data starting from the field data are shown. Sketch diagrams of the elaboration processes applied during several phases of the whole processing have been constructed. The used software are the Promax2D (Landmark Ltd.) and the Seismic Unix (Colorado School of Mines). The steps of the seismic data processes included the pre-processing, the sorting, the velocity analysis, the normal move-out (NMO), the stacking, the band-pass filtering, the multiple removals, the predictive de-convolution and the spiking de-convolution.
Exact analysis of MHD Walters’-B fluid flow with non-singular fractional derivatives of Caputo-Fabrizio in the presence of radiation and chemical reaction
Authors: Asjad Muhammad Imran , Aleem Maryam , Riaz M. Bilal
Published: March 2019

The present article reports the applications of Caputo-Fabrizio time-fractional derivatives. This article generalizes the idea of unsteady MHD free convective flow in a Walters.-B fluid with heat and mass transfer study over an exponential isothermal vertical plate embedded in a porous medium. The governing equations are converted into dimensionless form and extended to fractional model. The generalized Walters-B fluid model has been solved analytically using the Laplace transform technique. From the general solutions we reduce limiting solutions when  to the similar motion for Newtonian fluid. The corresponding expressions for and Nusselt and Sherwood numbers are also assessed. Numerical results for velocity, temperature and concentration are demonstrated graphically for various factors of interest and discussed. As a result, we have plotted the influence of fractional parameter on fluid flow and drawn comparison between fractional Walters’-B and fractional Newtonian fluid and found that fractional Newtonian fluid is faster than fractional Walters’-B fluids.

Published: March 2019

In this study, the effect of porogenic solvents on pore size distribution of the polycaprolactone (PCL) thin films was investigated. Five thin PCL films were prepared using the solvent-casting method. Chloroform, Methylene Chloride (MC) and three different compositions of MC/ Dimethylformamide (DMF) (80/20, 50/50 and 20/80) were used as solvents. Scanning Electron Microscopy (SEM) investigations were employed to study morphology and consequently the pore size distribution of the prepared films. The PCL films made by chloroform and MC as a solvent were completely non-porous. Whereas the other films (made by a combination of MC and DMF) showed both uni-modal and bi-modal pore size distributions.

Authors: Ahrendt Kai , Scalise A. , Sterr H. , Müller F. , Ruljevic I.
Published: March 2019

Based on GIS data sets an add-on for a coastal classification system was developed which takes Ecosystem Services (ESS) into account. The coastal area is segmented and afterwards classified. The segmentation is based on Google Earth. Each segment can be characterized by 10 different features including ecosystem services perpendicular to the coastline. If one of the features is changing a new segment will be specified. Therefore, a world-wide application is possible. Tests show that the classification can be easily done. The included ESS can be used to develop a vulnerability index for future development, e.g. for the years 2050 and 2100, based on scenarios for climate and demographic land use change.
Why do birds matter to us-a perspective from Kashmir valley, India in light of declaration of 2018 as the year of birds?
Authors: Tariq Khurshid Ahmad
Published: March 2019

The year 2018 has been declared as the Year of Birds with the aim of celebrating and protecting them. Birds are mysterious, cheerful and a marvellous creation with some unique and peculiar features. They are ecologically crucial in maintaining the balance of many ecosystems by sustaining various food chains and energy cycles. With their colourful bright plumage they enrich the natural scenic beauty of earth. Their migration, foraging, singing, breeding and nesting behaviour is quite astonishing. Birds make a variety of calls, sounds and songs with a language as complex as any spoken words that have many meanings, purposes and uses. Birds are the indicators of climatic conditions, natural calamities and bio-indicators of potential human impact and environmental degradation. Birds are facing continuous natural and anthropogenic threats due to multiple problems in the environment. The unregulated and unsustainable tourism and poaching threatens the habitat of so many game birds. Climate change, chemical use, loss of food source, overharvesting are the other impacts on bird loss. Awareness about stopping of habitat destruction, indiscriminate poaching birds, and regulated bird watching is the need of the time. We need to use more resources and put more sincere efforts for their management and conservation in view of the changing environment. Climate change has already altered the biological life on this planet, it would be interesting to know how climate change threatens bird’s life and survival. That will enable us in true sense to fulfil the objectives of the year of birds.
Biotechnological interventions for sustainable conservation of plant genetic resources in the scenario of climate change

Published: March 2019

Climate change is an unequivocal fact and its impacts are already perceptible today. Climate change will profoundly alter the present conditions of agriculture in almost all countries with variable severity from region to region. On one hand unpredicted changes in climatic parameters are likely to threaten the production and productivity of economically important plant species particularly that of food crops, at the same time agriculture productivity requires significant increase to meet the expected growth in demand for food by the ever increasing world population. Conservation and sustainable use of diversity present in plant genetic resources and traditional knowledge of germplasm within and among plant species represent economic, scientific and societal value which has tendency to solve the food security problems erupt due to expanding global population. An advance made in biotechnology field such as in vitro culture technology, cryopreservation and molecular markers technology has generated significant contributions to improve the methods of conservation of rare and endangered plant genetic resources and traditional knowledge of germplasm and their valuable management in an effective way. A strategic and forward vision for conservation of plant genetic resources and traditional knowledge of germplasm and sustainable use of plant resources in the 21st century is of far reaching significance for sustainable development.
Salinity: A primary growth driver of mangrove forest
Authors: Mitra ABHIJIT
Published: March 2019

The biomass of three dominant mangrove species (Sonneratia apetala, Avicennia alba and Excoecaria agallocha) in the Indian Sundarbans, the designated World Heritage Site was evaluated to understand whether the biomass vary with spatial locations (western region vs. central region) and with seasons (pre-monsoon, monsoon and post-monsoon). The reasons for selecting these two regions and seasons are the contrasting variation in salinity. Among the three studied species, Sonneratia apetala showed the maximum biomass followed by Avicennia alba and Excoecaria agallocha. We also observed that the biomass varied significantly with spatial locations (p<0.05), but not with seasons. The variation may be attributed to different environmental conditions to which these forest patches are exposed to.

The Improvement of Phytomediation on the Treatment Effectiveness of Heavy Metals with Energy Sunflower Plants with Calcium Peroxide and Phytohormones
Authors: TEH T Y , Wu Wuminhao , Chen Kf , Peng Yp
Published: March 2019

Phytomediation is an environmentally friendly green rehabilitation technology that is often incorporated with an application to improve calcium peroxide and phytohormones required for the growth of agricultural plants with the expectation to improve the effectiveness of plant rehabilitation. This study mainly consists of two parts: (1) water culture experiment and (2) pot culture experiment. In the water culture experiment, we attempt to understand the influence of the addition of calcium peroxide, phytohormones (IAA and GA3) and a chelating agent on the growth of sunflower plants. From the growth, we are then able to know the effectiveness of the addition of phytohormones. However, in the pot culture experiment, when hormones and the chelating agent EDTA are introduced to different plant groups at the same time, if the nutrition in the water required by plants is not available, the addition of the hormone cannot negate the toxicity caused by EDTA. In terms of calcium peroxide, due to quick release of oxygen in water, this study fails to apply calcium peroxide to the water culture experiment.     When the pot culture experiment is used to examine the influence of hormones at different concentration levels on the growth of sunflowers, GA3 10-8M is reported to have the optimal effectiveness, followed by IAA 10-8M; IAA 10-12M has the lowest effectiveness. According to an accumulation analysis of heavy metals at different levels, GA3 concentrates in leaves to transport nutrition in soil to leaves. This results in an excellent TF value of 2.329G of GA3 than 1.845 of the control group indicating that the addition of the hormone and chelating agent to GA3 increases the TF value and the chelating agent is beneficial to the sunflower plant. If we examine phytoattenuation ability, the one-month experiment was divided into three stages for ten days each. The concentration level of heavy metals in the soil at each stage dropped continuously while that of the control group decreased from 31.63 mg/kg to 23.96 mg/kg, GA3 from 32.09 mg/kg to 23.04 mg/kg and EDTA from 30.65 mg/kg to 25.93 mg/kg indicating the quickest growth period of the sunflowers from the formation of the bud to blossom. During the stage, the quick upward transportation of nutrition results in quick accumulation of heavy metals; the accumulated speed of heavy metals is found higher than that of directly planted plants. This study shows an improvement in the effectiveness of the addition of hormones on plant extraction and when rehabilitation is incorporated with sunflowers with the beginning bud formation, better treatment effectiveness can be reached.

Waste management using vermicompost derived liquids in sustainable horticulture
Authors: Shirani Bidabadi Siamak
Published: March 2019

The technology of vermicomposting containing their leachates, teas and other extracts such as vermiwash as a result of earthworm action is widely applied for safe management of agricultural, industrial, domestic and hospital wastes. Remediation of polluted soils, improving crop productivity and inducing the resistance against biotic and abiotic stresses are other advantages of vermicompost derived liquids when used in agriculture. Contrary to the fact that chemical fertilizers are still widely used in agriculture, societies gradually become aware of the negative effects of these fertilizers on their health. Therefore, vermicompost derived liquids contain high amount of valuable plant nutrients which has the potential to be used as liquid fertilizer. This paper reviews the potential of vermicompost derived liquids as as an efficient combination of nutrient source of vermicompost derived liquids contributing to plant growth and acting as a deterrent to biotic and abiotic stresses.

Authors: Yadav R.C. , Yadav Jaya
Published: March 2019

Some developmental projects are created by people- private -partnership (PPP), particularly where recovery is acquirable by levying the users. Such PPPs are successful for construction of roads, bridges, running toilet facilities and conveyance facility in mode of use and pay.  Likewise, public Scientist Partnership (PSPs) will be successful, where monitored impacts can be used to derive benefit. But, such example cases are not so popular in utilizing new research results and derive benefits from natural resources and enhance productivity. There exists need of similar partnership projects in research area. In this study modality of the PSP to create boost engine for natural resource conservation and bringing economic prosperity is established. A novel PSP launch was synthesized on useful food crop viz finger millet (Elusiane corcona (l)), known since long past, and now regaining popularity. It was possible to enhance additional annual production of 5.755 million Tonnes of finger millet grain, equivalent to additional income of Rs 11,510 crores. Against this the scientist partnership share was 0.49x million Tonnes grain and economic equivalency of Rs 992 crores, which was just 7-8%, with same level of input in agriculture. Additional benefits were sustainability of production and resources consecration, reduction of Green House Gas emission (GHGs), particularly nitrous oxide (N2O), largely emanating from agriculture and responsible for depletion of ozone layer. The finger millet stiff stem will be useable for production of ply-board filling material that will be innovative  building material for housing and infrastructure developments. and making furniture.

Published: March 2019

This paper deals with joint production and corrective maintenance problem of a transported material network failure-prone manufacturing system along which two aspects are supposed. First, each non-identical machine are subject to degradation with failure phenomena. When a failure occurs, system is either repaired or replaced with new one, repairing activity not only degrades machine operating state, but also increases with the next repair time. Second, optimality production control policy called Modified Hedging Point Policy (MHPP) and Modified Hedging Corridor Policy (MHCP) are applied for given network machine. The aim of this article is to find decision variables so as to minimize incurred cost function, including repair costs, stock related costs (i.e., holding costs, backlog and shortage) and setup cost, over an finite-horizon time. Simulation experimental approach with meta-heuristic algorithm is applied to obtain near-optimum decision variables.

The Monti di Pietà in the Middle Ages from a Privileged Point of View: the Marches
Authors: Lambertini Roberto
Published: March 2019

Studies concerning the Monti di Pietà have quite a long tradition; in the past decades, however, this institution has been studied from new perspectives. After arguing in favor of the Marches (central Italy) as a privileged view angle on the phenomenon, the paper touches upon some complex relationships existing between political authorities and Observant Franciscan preachers, who campaigned in favor of the Monti on explicit invitation of local authorities. The question of the actual functioning of the Monti is also connected with the mechanisms of social inclusion and exclusion; the role of Jewish moneylenders, who were the major targets of Observant preaching in favor of the Monti, is also a key issue for the understanding of the institution.

The paper defends the thesis that a proper understanding of Sturzo’s thought and work can be achieved only within the perspective of the civil economy paradigm. After exposing the main pillars characterizing the civil economy research program, the argument proceeds indicating the reasons why Sturzo did not consider adequate, for a country like Italy, the proposal of the social market economy. The paper concludes suggesting same reasons to explain the fin de non recevoir of the political establishment with respect to Sturzo’s testimony.
Reciprocity in the Civil Economy: a Critical Assessment
Authors: Martino María Guadalupe , Müller Christian
Published: March 2019

The civil economy approach is an attempt to reconcile economic market interactions with the normative standards of traditional virtue ethics. We analyze critically some of its main elements with a special focus on the concept of reciprocity, which plays a central role in the whole approach. Its strengths include, among others, virtue orientation, emphasis on happiness rather than utility, and in particular the notion of reciprocity. However, we argue that this concept of reciprocity would on average not be incentive compatible, and from a methodological point of view, the implied hypothesis of a homo reciprocans is not a viable alternative to the standard model of homo oeconomicus. We also consider that the approach is not entirely new, as it shares many characteristics with the social market economy conception.
Civil Economy in the Social Market Economy: a Theoretical Perspective
Authors: Felice Flavio
Published: March 2019

What do we mean by “civil” and “civil society”? This paper attempts to describe a complex notion of “civil economy” in Sturzo’s theoretical perspective of the social market economy. According to this political theory, “civil” is not opposed to “market,” which is not opposed to “the political” (the state). Rather, instead of being the transmission belt between the state and market, civil is the galaxy in which we find also the market and the state (but not only), each with its own functions. This tradition – rooted in Christianity – was able to oppose both Nazi and communist totalitarianism, while many Catholics made an impossible attempt to exhume corporatism.
Sources of “Public Reason” in Europe: Perspectives from Theological Ethics
Authors: Junker-Kenny Maureen
Published: March 2019

Welcoming the turn toward including normative conceptions of the human into the remit of economics, this paper compares philosophical frameworks that guide principles such as dignity and justice as one source of theological ethics. Recent political crises show the importance of analyzing the public sphere with which Christian ethics in its various approaches interacts. The place given to religions in Rawls’s and Habermas’s concepts of “public reason” is compared with Ricoeur’s understanding of religions as cofounding traditions. They can contribute to a necessary exchange of memories, also of conflict and conquest, inspired by the undelivered hopes of their own founding memories, precluding triumphalism and fostering “intellectual solidarity” (Hollenbach).
The Effect of Survey Mode on Data Quality: Disentangling Nonresponse and Measurement Error Bias
Authors: Felderer Barbara , Kirchner Antje , Kreuter Frauke
Published: March 2019

More and more surveys are conducted online. While web surveys are generally cheaper and tend to have lower measurement error in comparison to other survey modes, especially for sensitive questions, potential advantages might be offset by larger nonresponse bias. This article compares the data quality in a web survey administration to another common mode of survey administration, the telephone.

The unique feature of this study is the availability of administrative records for all sampled individuals in combination with a random assignment of survey mode. This specific design allows us to investigate and compare potential bias in survey statistics due to 1) nonresponse error, 2) measurement error, and 3) combined bias of these two error sources and hence, an overall assessment of data quality for two common modes of survey administration, telephone and web.

Our results show that overall mean estimates on the web are more biased compared to the telephone mode. Nonresponse and measurement bias tend to reinforce each other in both modes, with nonresponse bias being somewhat more pronounced in the web mode. While measurement error bias tends to be smaller in the web survey implementation, interestingly, our results also show that the web does not consistently outperform the telephone mode for sensitive questions.
How Standardized is Occupational Coding? A Comparison of Results from Different Coding Agencies in Germany

Published: March 2019

As occupational data play a crucial part in many social and economic analyses, information on the reliability of these data and, in particular on the role of coding agencies, is important. Based on our review of previous research, we develop four hypotheses, which we test using occupation-coded data from the German General Social Survey and the field test data from the German Programme for the International Assessment of Adult Competencies. Because the same data were coded by several agencies, their coding results could be directly compared. As the surveys used different instruments, and interviewer training differed, the effects of these factors could also be evaluated.

Our main findings are: the percentage of uncodeable responses is low (1.8–4.9%) but what is classified as “uncodeable” varies between coding agencies. Inter-agency coding reliability is relatively low κ ca. 0.5 at four-digit level, and codings sometimes differ systematically between agencies. The reliability of derived status scores is satisfactory (0.82–0.90). The previously reported negative relationship between answer length and coding reliability could be replicated and effects of interviewer training demonstrated. Finally, we discuss the importance of establishing common coding rules and present recommendations to overcome some of the problems in occupation coding.
Modeling a Bridge When Survey Questions Change: Evidence from the Current Population Survey Health Insurance Redesign
Authors: O’Hara Brett , Medalia Carla , Maples Jerry J.
Published: March 2019

Most research on health insurance in the United States uses the Current Population Survey Annual Social and Economic Supplement. However, a recent redesign of the health insurance questions disrupted the historical time trend in 2013. Using data from the American Community Survey, which has a parallel trend in the uninsured rate, we model a bridge estimate of the uninsured rate using the traditional questions. Also, we estimate the effect of changing the questionnaire. We show that the impact of redesigning the survey varies substantially by subgroup. This approach can be used to produce bridge estimates when other questionnaires are redesigned.

The aim of this study is to evaluate and compare the impacts of heat recovery ventilation (HRV) and exhaust air heat pump (EAHP)-based solutions used in renovated buildings, which make it possible to reach performance class C in district heating (DH) area CO2 emissions, primary energy consumption and total energy costs for consumers. Evaluation is based on the methodology presented in the previous research paper [1]. Calculation results show that the use of EAHP has a negative impact on DH sustainability (heat losses in the DH network, DH heat price, reduced consumption of DH heat) and CO2 emissions related to energy delivery (heat and electricity) to consumers in the DH area. Positive aspects of the EAHP use include the fact that almost the same primary energy consumption level can be achieved with lesser (up to 7 %) annual costs (annual capital costs, DH heat costs and electricity costs) and lower initial investments (about 10 %). At the same time, every renovated building with EAHP will experience a negative impact on heat prices. In DH areas where almost all buildings are renovated with EAHP, cost savings are not as evident compared to buildings with HRV in DH areas where the use of parallel consumption solutions (EAHP) is minimized. It is reasonable to promote these renovation packages and solutions that benefit the building’s primary energy reduction, and also do not increase electric energy consumption (additional electric power generators are needed) and do not damage DH networks.

Epimedium elatum (Morren & Decne) of family Berberidaceace is a rare perennial medicinal plant, endemic to high altitude forests of Northwestern Himalayas in India. Ethnobotanically, it has been used as an ingredient for treatment of bone-joint disorders, impotence and kidney disorders in Kashmir Himalayas. Phytochemically, it is rich in Epimedin ABC and Icariin; all of these have been demonstrated to possess remarkable biological activities like PDE-5 inhibition (treatment of erectile dysfunction), anticancer, antiosteoporosis antioxidant and antiviral properties. The present investigation reports its traditional usage, comprehensive distribution and conservation status from twenty ecogeographical regions in Kashmir Himalayas, India. The species was reported from Gurez valley for the first time. Numerous threats like excessive grazing, deforestration, habitat fragmentation, tourism encroachment, landslides and excessive exploitation have decreased its natural populations in most of the surveyed habitats. Consequently, its existence may become threatened in near future if timely conservation steps are not taken immediately by concerned stakeholders involved in medicinal plant research. Moreover, use of plant tissue culture techniques is recommended for development of its in vitro propagation protocols. Therefore, introduction of this medicinal plant in botanical gardens, protected sites and development of monitoring programmes are needed for its immediate conservation in Northwestern Himalayas, India.

The indiscriminate use Â of chemicals fertilizers and pesticides have not only deteriorated Â Â the environment but also the groundwater resources as well .Their intensive consumption Â Â causesÂ  Â deleterious effects on plant, animal and aquatic ecosystems thereby causing serious problems related to health. Â Â Since these Â are one of theÂ  factors Â which are Â responsible for Â the contamination of air, water and terrestrial ecosystems and also Â the cause of Â Â disruption of biogeochemical cycling, Â it is extremely important to bring down ,the toxicity Â levels Â that these chemicals impose on the environment, by the use of effective technology, which Â is Â Â Â cost effective and safe. It has been suggested that biodegradation becomes an attractive option for destruction of pesticides since it utilizes a natural process and offers the potential for being cost effective as well as safe technology Thus the present study deals with the isolation and Â Â use indigenous bacteria for degradation ofÂ  an organophosphorous pesticide- methyl parathion Â present in the soil samples which were collected from the pesticide contaminated agricultural field.

Septate gregarines or Cephaline gregarines are a group of parasitic protozoans of Grasshopper. Eugregarines are the most common; these species inhabit the midgut though rarely pathogenic in the mid-gut, they have been reported to block the gut of the host. Those inhabiting the gastric caeca cause serious pathologies than the midgut-inhabiting species. Some of the best known genera found in Manipur are Gregarina, Phleobum, Didymophyes, Amphiplatyspora, Lepismatophila, Quadruspinospora and Quadruknobspora. The study reports the morphological details of 16species of the above genera collected from Imphal. Illustrative diagrams and photomicrographs are provided for better species identification.

La consagración de la selfie: una historia cultural
Authors: Gunthert André , Aparacio Erazo Jorge Luis
Published: March 2019

El término “selfie” corresponde a un proceso de identificación tardío de un conjunto de prácticas reflexivas fotográficas o de video, relacionadas con el surgimiento de una estética de la subjetividad. Al explorar la articulación entre la autonomía del registro y la participación del actor en la acción, al igual que el despegue producido por los usos conversacionales, este artículo muestra que una controversia mediática desencadenó este fenómeno. La denuncia en 2013 del carácter narcisista de la auto representación o la falta de respeto a los valores y normas, presenta la autofotografía a manera de subcultura. Esta condena implicó una respuesta de adhesión a un gesto ahora identificado como una firma impertinente y progresiva, lo que contribuye a su promoción. La controversia consagró a la selfie al estilo de una forma cultural y la impuso como la práctica fotográfica más representativa de la expresión visual contemporánea.
