Resistivity-depth Imaging with the Airborne Transient Electromagnetic Method Based on an Artificial Neural Network
Authors: Feng Bing , Zhang Ji-feng , Li Dong , Bai Yang
Published: December 2020

We developed an artificial neural network to map the distribution of geologic conductivity in the earth subsurface using the airborne transient electromagnetic method. The artificial neural network avoids the need for complex derivations of electromagnetic field formulas and requires only input and transfer functions to obtain a quasi-resistivity image. First, training sample set from the airborne transient electromagnetic response of homogeneous half-space models with different resistivities was formed, and network model parameters, including the flight altitude, time constant, and response amplitude, were determined. Then, a double-hidden-layer back-propagation (BP) neural network was established based on the mapping relationship between quasi-resistivity and airborne transient electromagnetic response. By analyzing the mean square error curve, the training termination criterion of the BP neural network was determined. Next, the trained BP neural network was used to interpret the airborne transient electromagnetic responses of various typical layered geo-electric models, and the results were compared with that from the all-time apparent resistivity algorithm. The comparison indicated that the resistivity imaging from the BP neural network approach was much closer to the true resistivity of the model, and the response to anomalous bodies was better than that from an all-time apparent resistivity. Finally, this imaging technique was used to process field data acquired by employing the airborne transient method from the HuaYin survey area. Quasi-resistivity depth sections calculated with the BP neural network and the actual geological situation were in good.

Published: December 2020

The apparel industry is one of the largest export earning industries in Sri Lanka and provides ample job opportunities for society. Despite that industry is facing a large labour deficiency which can lead to a shift in the industry in near future. It stresses that there is a less attraction of potential employees towards the industry. Employer attractiveness is the envisioned benefits that a potential employee sees in working for a specific organization consist with five dimensions, namely interest value, social value, economic value, application value and development value. The dissimilarity of potential employees can be caused to prevailed differences in employer attractiveness. Therefore this study aims to investigate what demographic differences are exist in the employer attractiveness in terms of gender (Male & Female), age (Young & Middle-aged) and previous experiences in employment (Experienced & In-experienced) of potential employees in the apparel industry. Findings revealed that the perceived level of the employer attractiveness varies according to the gender, age and previous experiences in employment. The highest attracting dimension of males was economic value while the least was application value. Females were more attracted to social value and less attractive to development and interest value. Both young and middle-age people tend to attract more towards the economic value while the young category is least attracted to development value and middle age category is to application value. Experienced employees are highly attracted to the economic value of the employer while least attractive to the application value. Inexperienced people tend to attract more towards social value and least to development value.

Published: December 2020

In light of the fourth industrial revolution, human resources management (HRM) is considered to be an integral part of any competitive organization and it is responsible for shaping organizational behavior and culture. With the increasing awareness of the industrial impact on the environment, sustainability innovation is a vital discourse for scholars, academicians, and practitioners. This work uses literature from diverse schools of thought that explored the role of the human resource discipline in advancing sustainability innovation. This paper also presents a unique model for human resource and talent development practitioners towards an authentic response to eco-sustainability innovation. A contextualized matrix on implications for sustainability (Crew 2010) incorporating special approaches for sustainability innovation (McCarthy, Garavan, and O’Teele, 2003), green initiatives of human resource department (Milliman, 2013) and the promotion of sustainability culture (Blake, 2016) was outlined that serves as authentic approach to eco-sustainability for practitioners to realistically carry out human resource initiatives in their respective organization. This study further directs human resource professionals to act as boundary spanners in order to facilitate strategic teams who are paramount to responding to the external environment for organizational performance.

THE DEFINING MOMENTS OF BUSINESS SUCCESS AMONG WOMEN MICRO-ENTREPRENEURS
Authors: Gano-an Jonathan C
Published: December 2020

Empirical studies indicate that the unprecedented number of women who engaged in entrepreneurial endeavors is significantly increasing and their participation in entrepreneurship was fueled by their experiences, role at home, and societal norms. This paper defines the business success and illuminates its meaning from the perspective of women micro-entrepreneurs. A systematic literature review approach was employed in using pre-determined keywords. For the purpose of this study, these literatures are limited within the scope of women micro-entrepreneurship which are published in peer reviewed journals from 2001 to 2019. Findings of this literature review showed that women micro-entrepreneurs used subjective terms to define and interpret success instead of solely using quantitative criteria. From the selected readings, the definition of success has been refined and illuminated and expressed such in specific circumstance that translates to ‘moments of success’. Among the moments that define their success are autonomy, personal contentment, enjoyment, being able to control destiny, survival during hard times, and the skills developed. These moments further have afforded them to attain empowerment allowing them to gain status in the society. Philosophically, most of these researches are considered within post-positivist and constructivist worldviews and it is suggested that future studies, in view of multiple realities and innovative approach, a pragmatist view may be considered.

The focus of the article is on how knowledge is created, who creates knowledge, how knowledge is co-constructed, whose knowledge is excluded and how knowledge is being used to challenge inequalities and strengthen social movement capacity. This article grew from a fascinating conversation that the three of us had in Montreal in September of 2019. We decided to share our stories about knowledge and justice with a wider audience in part as a way for us to reflect further on the meaning of our initial conversation, but also to invite others into the discussion. Baptiste Godrie works in a research centre (CREMIS) affiliated  with Quebec’s health care and social services system, Isabel Heck works with the anti-poverty organization Parole d’excluEs, both affiliated to universities, and Budd Hall works at the University of Victoria and is the Co-Chair of the UNESCO Chair in Community-Based research and social responsibility in higher education.
Foraging habitat of North Atlantic right whales has declined in the Gulf of St. Lawrence, Canada, and may be insufficient for successful reproduction
Authors: Gavrilchuk K , Lesage V , Fortune SME , Trites AW , Plourde S
Published: December 2020

Climate-induced changes in calanoid copepod (Calanusspp.) availability in traditional feeding areas might explain why a large proportion of the North Atlantic right whaleEubalaena glacialispopulation has fed in the Gulf of St. Lawrence (Canada) in recent years. However, little is known about the distribution of copepods in the gulf, and whether their abundance is sufficient to energetically sustain right whales. We used a mechanistic modelling approach to predict areas within the gulf that have foraging potential for adult female right whales, based on the annual energetic needs of resting, pregnant and lactating females, and their theoretical prey density requirements. We identified suitable foraging areas for right whales by coupling a foraging bioenergetics model with a 12 yr data set (2006-2017) describing the abundance and 3-dimensional distribution of late-stageCalanusspp. in the gulf. Prey densities in the southern gulf (from Shediac Valley to the Magdalen Islands) supported all 3 reproductive states in most (≥6) years. However, foraging habitat became progressively sparse in the southern gulf over time, with noticeably less suitable habitat available after 2014. Few other potentially suitable foraging areas were identified elsewhere in the gulf. Overall, the availability of foraging habitat in the gulf varied considerably between years, and was higher for resting females than for pregnant and lactating females. Our findings are consistent with the recent low calving rates, and indicate that prey biomass in the Gulf of St. Lawrence may be insufficient in most years to support successful reproduction of North Atlantic right whales.
Improving farm practices and productivity through training needs assessment of sugarcane farmers: the case of Davao Mill District, the Philippines
Authors: Padilla-Fernandez Marietta Dina , Gonzales Joseph P. , Mamauag Miguel J. C.
Published: December 2020

The need to improve the farm practices and productivity in the Davao mill district was examined through Training Need Assessment.  The aim is to develop a well-designed and need-based training program for its sugarcane farmers. A two-stage stratified random sampling technique was employed to select 112 respondents. A well-structured questionnaire was used and data were analyzed using Likert Scale and multiple regression analysis. The areas of training needs identified for sugarcane production were on the application/computation of chemical fertilizer, soil fertility management, selection of varieties, seizing fertilization and irrigation before harvesting, managing disease control and designing a weed control program. The information on the processing of sugar, the current situation of the sugarcane industry in the domestic and world markets, and farm plan and budgeting were also identified. For other crop production, the training needs were on swine, corn production and poultry raising. Farmers also need training on product quality and packaging and marketing for muscovado, vinegar and wine making for their source of livelihood. The relational analysis showed a positive and significant relationship between age and access to high yielding varieties with training needs expressed by the farmers on sugarcane production. Training could be more effective by targeting older farmers as they seemed to be more receptive to technology although young farmers also need to be trained due to succession in sugarcane farming. The study recommends to assess the interventions given to the Davao MDDC particularly the nursery farms under the Rapid Propagation and Distribution Program of SRA especially on the accessibility of HYV seeds. It also recommends for SRA and the Davao MDDC to increase extension contact and develop training modules and re-orient training schedules with training needs expressed by the farmers to improve the farm practices and productivity in the study area.

RUS DİPLOMATİK BELGELERİNE GÖRE BİRİNCİ DÜNYA SAVAŞI'NDA BULGARİSTAN'IN TARAFSIZLIĞI MESELESİ
Authors: BAYRAMOL Eray
Published: December 2020

Balkan Savaşları'nın Bulgaristan üzerinde ortaya çıkardığı sonuçlar Bulgaristan'ı yeni stratejiler belirlemeye sevk etti. Özellikle İkinci Balkan Savaşı'nda Rusya'dan istediği desteği alamayan Bulgaristan, Birinci Dünya Savaşı'nda Rus politikalarına karşı temkinli davrandı. Karşılıklı çıkarlar üzerine kurulu Türk-Bulgar ilişkileri neticesinde Osmanlı Devleti Bulgaristan'ı bir müttefik olarak kendi tarafına çekmek istedi. Sonuç itibariyle Bulgaristan, Birinci Dünya Savaşı'na Osmanlı Devleti saflarında girme kararı aldı.

Birinci Dünya Savaşı'na İtilaf Devletleri saflarında giren Rusya ise, savaştığı cepheleri olabildiğince dar tutmak niyetindeydi. Bu sebeple savaştan hemen önce Osmanlı Devleti'nin tarafsızlığını devam ettirmesi yönünde girişimlerde bulunduğu gibi Bulgaristan'ın da savaşta tarafsız kalması için çeşitli politikalar geliştirdi. Bulgaristan'ın Osmanlı Devleti saflarında savaşa girmesi, Osmanlı Devleti ile müttefikleri arasındaki kara bağlantısının sağlanması anlamına gelmekteydi. Böylesi bir gelişmenin kendisi için yıkım olacağını gören Rusya, Bulgaristan'ın tarafsız kalması ya da Rusya saflarında savaşa girmesi için uzun uğraşlar verdi.

Rusya'nın bu girişimleri Rusya Dışişleri Bakanlığı ile İstanbul ve Sofya'daki diplomatik misyonları arasındaki yazışmalara konu olmuştur. Bu çalışmada Rusya'nın Birinci Dünya Savaşı'nda Bulgaristan'ı İttifak Bloğu'ndan uzak tutma çabaları, Rusya'nın diplomatik belgelerine dayanılarak ortaya konulmaya çalışılacaktır.

In this protocol, Fucoidan (FU), a fucose-rich sulfated polysaccharide extracted from brown algae Fucus vesiculosus was used for in situ preparation of magnetic Fe3O4@FU. Nanoco magnetic properties of Fe3O4@FU were investigated by energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), Brunauer–Emmett–Teller (BET) adsorption method, and vibrating sample magnetometer (VSM). The catalytic activity of Fe3O4@FU was employed for the synthesis of tri- and tetra-substituted imidazoles through three- and four-component reactions respectively, between benzyl, aldehydes, NH4OAc and benzyl, aldehydes, NH4OAc, and amine under reflux in ethanol. It is worth nothing that excellent yields, short reaction times, chromatography-free purification, and environmental friendliness are highlighted features of this protocol.

Silk fibroin (SF) is a natural protein largely used in the textile industry but also in biomedicine, catalysis, and other materials applications. SF is biocompatible, biodegradable, and possesses high tensile strength. Moreover, it is a versatile compound that can be formed into different materials at the macro, micro- and nano-scales, such as nanofibers, nanoparticles, hydrogels, microspheres, and other formats. Silk can be further integrated into emerging and promising additive manufacturing techniques like bioprinting, stereolithography or digital light processing 3D printing. As such, the development of methodologies for the functionalization of silk materials provide added value. Inorganic nanoparticles (INPs) have interesting and unexpected properties differing from bulk materials. These properties include better catalysis efficiency (better surface/volume ratio and consequently decreased quantify of catalyst), antibacterial activity, fluorescence properties, and UV-radiation protection or superparamagnetic behavior depending on the metal used. Given the promising results and performance of INPs, their use in many different procedures has been growing. Therefore, combining the useful properties of silk fibroin materials with those from INPs is increasingly relevant in many applications. Two main methodologies have been used in the literature to form silk-based bionanocomposites: in situ synthesis of INPs in silk materials, or the addition of preformed INPs to silk materials. This work presents an overview of current silk nanocomposites developed by these two main methodologies. An evaluation of overall INP characteristics and their distribution within the material is presented for each approach. Finally, an outlook is provided about the potential applications of these resultant nanocomposite materials.

Inclined wells has recently been adopted to develop fractured-vuggy carbonate hydrocarbon reservoirs (FVCHRs) composed by matrix, fracture and vug system. Therefore, it is significant for us to describe pressure transient of inclined well for FVCHRs. In this paper, it is assumed that vug and fracture system connect with wellbore, and inter-porosity flow from vug to fracture system appears. Therefore, the pressure transient responses model of inclined well with triple-porosity dual-permeability behavior was built. The model is solved by employing Laplace integral transform and finite cosine Fourier transform. Real-domain solution of the model is obtained by Stehfest inversion algorithm. On the basis model of the published paper, the solution of the simplified model of this paper was validated with horizontal and vertical well of FVCHRs with triple-porosity dual-permeability behavior, and results reach a good agreement. Type curve, according to pressure derivative curve characteristic, can be divided into eight flow regimes, which includes wellbore storage, skin reflect, early vertical radial flow, top and bottom boundary reflection, linear flow, inter-porosity flow from vug to fracture, inter-porosity from matrix to vug and fracture and pseudo-radial flow regimes. The influence of some vital parameters (inclination angle, inter-porosity flow coefficient, well length and permeability ratio etc.) on dimensionless pressure and its derivative curves are discussed in detail. The presented model can be used to understand pressure transient response characteristic of inclined wells in FVCHRs with dual-permeability behavior.

We untangled key regions of the genetic architecture of grain yield (GY) in CIMMYT spring bread wheat by conducting a haplotype-based, genome-wide association study (GWAS), together with an investigation of epistatic interactions using seven large sets of elite yield trials (EYTs) consisting of a total of 6,461 advanced breeding lines. These lines were phenotyped under irrigated and stress environments in seven growing seasons (2011–2018) and genotyped with genotyping-by-sequencing markers. Genome-wide 519 haplotype blocks were constructed, using a linkage disequilibrium-based approach covering 14,036 Mb in the wheat genome. Haplotype-based GWAS identified 7, 4, 10, and 15 stable (significant in three or more EYTs) associations in irrigated (I), mild drought (MD), severe drought (SD), and heat stress (HS) testing environments, respectively. Considering all EYTs and the four testing environments together, 30 stable associations were deciphered with seven hotspots identified on chromosomes 1A, 1B, 2B, 4A, 5B, 6B, and 7B, where multiple haplotype blocks were associated with GY. Epistatic interactions contributed significantly to the genetic architecture of GY, explaining variation of 3.5–21.1%, 3.7–14.7%, 3.5–20.6%, and 4.4– 23.1% in I, MD, SD, and HS environments, respectively. Our results revealed the intricate genetic architecture of GY, controlled by both main and epistatic effects. The importance of these results for practical applications in the CIMMYT breeding program is discussed.

NK cells are phenotypically and functionally diverse lymphocytes due to variegated expression of a large array of receptors. NK-cell activity is tightly regulated through integration of receptor-derived inhibitory and activating signals. Thus, the receptor profile of each NK cell ultimately determines its ability to sense aberrant cells and subsequently mediate anti-viral or anti-tumor responses. However, an in-depth understanding of how different receptor repertoires enable distinct immune functions of NK cells is lacking. Therefore, we investigated the phenotypic diversity of primary human NK cells by performing extensive phenotypic characterization of 338 surface molecules using flow cytometry (n = 18). Our results showed that NK cells express at least 146 receptors on their surface. Of those, 136 (>90%) exhibited considerable inter-donor variability. Moreover, comparative analysis of CD56bright and CD56dim NK cells identified 70 molecules with differential expression between the two major NK-cell subsets and allowed discrimination of these subsetsviaunsupervised hierarchical clustering. These receptors were associated with a broad range of NK-cell functions and multiple molecules were not previously associated with predominant expression on either subset (e.g. CD82 and CD147). Altogether, our study contributes to an improved understanding of the phenotypic diversity of NK cells and its potential functional implications on a cellular and population level. While the identified distinct signatures in the receptor repertoires provide a molecular basis for the differential immune functions exerted by CD56bright and CD56dim NK cells, the observed inter-individual differences in the receptor repertoire of NK cells may contribute to a diverging ability to control certain diseases.

The morphology and taxonomy of three scuticociliates found in China, viz. Citrithrix smalli sp. nov., Homalogastra binucleata sp. nov., and Uronema orientalis Pan et al., 2015, were investigated. The small subunit ribosomal RNA (SSU rRNA) gene of these species, and the cytochrome c oxidase subunit I (COI) gene of Uronema orientalis, were sequenced and compared with those of related taxa to determine their systematic positions. The new monotypic genus Citrithrix gen. nov. is characterized by its lemon-shaped body, posteriorly located cytostome, dominant oral groove, and the compact structure of its multi-rowed membranelles 1 and 2 (M1, M2). Based on both morphological and molecular data, this new genus cannot be assigned to any known family and thus, a new family, Citrithrixidae fam. nov., is proposed within the order Philasterida. Homalogastra binucleata sp. nov., a brackish water form (salinity 2‰), differs from all congeners in having two macronuclear nodules. Uronema orientalis closely resembles the type population in all respects other than having fewer somatic kineties.

Boldness and aggressiveness are crucial behavioral traits in the field of animal personality, and both have important ecological and evolutionary significance. As swimming crabs (Portunus trituberculatus) are aggressive, their production is affected; thus, it is important to study their behavior. To assess the relationship between boldness and aggressiveness of male P. trituberculatus and the differences between their different life stages, we determined the individual differences in these two traits in juvenile and adult crabs under laboratory conditions. Based on the k-means cluster analysis, boldness of crabs is classified according to their rush to adventure, and aggressiveness of crabs is classified according to their aggressive behavior toward conspecifics. The results show that the personality classification of juvenile and adult crabs was consistent. Boldness was divided into three levels: bold, middle, and shy. Aggressiveness was divided into two levels: aggressiveness and non-aggressiveness. The personality of juveniles and adults P. trituberculatus males was significantly different; juveniles presented higher aggressiveness and lower boldness than adults. Additionally, a significant positive correlation between boldness and aggressiveness of adult crabs was verified (P = 0.001, ρ = 0.271). However, this correlation in juvenile crabs was not significant (P = 0.702, ρ = 0.042). These preliminary results indicate that the personality of P. trituberculatus males has developmental plasticity and adults have the boldness-aggressiveness behavioral syndrome.
