Kristevas teorier i en återvändsgränd
Authors: Järvstad Kristin
Published: June 2022

Julia Kristeva has been ver)' populär in the Scandinavian countries among feminist literary critics because of her subverting the essentialist definitions of woman by talking about 'the feminine', not as related to sex but as a linguistically and psychoanalytically founded term. But what is she actually saying about woman as a temporal and social being, the kind of being feminists are dealing with? And where in her theories floes the woman author fit in? In spite of woman's closeness to the semiotic and revolutionary aspects of language, due to her marginalized position in the phallocentric structure, she suffers from great difflculties, even psychically threatening ones according to Kristeva, when exploring this kind of language in her writing. The first article of some length which Kristeva has written about a female author cleai ly discloses an ambivalent stance: when discussing Duras she finds that Duras' language is not able to transcend her depressive melancholia in the way Dostoievski's is. On the whole, niale authors are able to use the semiotic aspects of language and tum it into an artistic ttiumph whereas women authors, like Virginia Woolf, Sylvia Plath and Maria Tsvetaeva, grapple with their mothers and thence are threatened by either madness or suicide. This is in accordance with Kristeva's view of the mother/- daughter-relationship where separation is all but impossible, whereas the little boy is taught to look upon himself as a distinct and separate being. According to Kristeva, woman is able to express herself mainly through her body, especially through her pregnancies, but this only leaves her where she was positioned long ago, as the sacred object of procreation. Kristeva is critical to feminism in many respects and therefore introduces an alternative of her own, namely tlie so called 'third generation' of feminism. As a solution to what she terms 'the war of the sexes' and the implacable difference that separates them. Kristeva proposes a deconstruction of the subject, down to its very nucleus, but in doing so removes ever\' trace of a politically and socially anchored feminism. The problem also is that the acomplishments of the former generations of feminism vanish. And what is the starting point of feminism once we have been told that the sexual differences belong to metaphysics, as Kristeva claims? After having left feminism with this ultimate deconstruction, there is hardly any possibilitiy of construction: the subversion of Kristeva's has been too thoroughgoing.
Det oskrivna fyrtiotalet

Published: June 2022

Vart tog kvinnorna vägen när männen skrev fyrtiotalets litteraturhistoria? På fyrtiotalet var de många och fullt synliga: Rut Hillarp, Elsa Grave, Maria Wineoch många fler. I litteraturhistorien har de alla hamnat i marginalernas väglösa land. De kvinnliga poeternas oskrivna historia är samtidigt en historia om hur synen på kön och pä litterärt värde vävs samman i litteraturens kanoniseringsprocess.

Ökad press på allt fler ensamstående mödrar
Authors: Björnberg Ulla
Published: June 2022

The article illuminates the situation for single mothers in the ex-communist countries - Poland, Russia (the European part), ex. DDR and in Sweden and West Germany. The purpose is to discuss the mothers' situation with reference to their relation to three spheres - tlie family and social networks, public social policies and the working life. One basic question that is if the situation of single women with children is more exposed tlian that of the married women, and what possible consequences this might have for themselves and their children. How do single mothers differ from married mothers in the respective countries as far as education, incomes, work and views on the future are concerned? Despite comprising economic and social dissimilarities between these countries, comparisons are interesting since we focus the comparisons on married and single mothers with children. Hereby we get a measure of the structures and processes within these countries, and it can be discussed whether these are generally applied or not. An important aspect is to what extent the social policies or other factors lead to different attitudes in the countries. The results show that the transformation in the former communist nations afflict particularly women, and only in a negative manner. Large groups of women are rejected from the labour märket, and end up in a situation of poverty and dependence. The investigations in all the countries show that single mothers are more exposed than married mothers. They run a greater risk of losing their jobs than the married mothers do, and they thus run a greater risk of ending up in miserable poverty - particularly the mothers in Poland and Russia. The situation of single mothers in Sweden is better from a material point of view. In spite of this, many lone mothers feel worried about their economy - a worry that can be expected to increase along with increasing fees for social services, child care, health- and medical care, increased residential costs etc. The results indicate that the largest disability that women have on the labour märket is not the motherhood in itself, nor is it the gender, but the absence of marriage, in combination with being female. Comprising international research shows that poverty and exposition in one-parent families tend to be reproduced to the next generation. There is no automatic relationship in the relation between divorce, one-parenthood and social problems. It is rather the stigmatisation in different forms that is concerned, in combination with shortages in the possibilities of support that can lead to an assimilation of prolems. Via stigmatising treatment, both the mothers and the children lose their dignity and their self-assured identity.
Det bor också kvinnor i det europeiska huset
Authors: Rosenbeck Bente
Published: June 2022

This article is based on Den möderne tid volume 5 in Det europceiske hus written together with Karin Liitzen. It focus on certain characteristic aspects in women's situation in the western world in the periode 1870 to 1945. The quality of the population became a central factor in modern society: object of population policy and social policy. This made women a key figure in the care of the population and in the reformation of industrial society ancl made gender central in many modern institutions. The western european marriage pattern characterised by high age at marriage and by a big part of a generation never marryingwasunique in the world. This pattern made it possible for young people to save money in their youth: money intended for their future marriage. This saving of money on a mass scale was important for the european "take off' into modern economic growth. This marriage pattern was also very important for women, who did not have to get married at young age. They had to earn their own living, and in order to get work they often had to move to the towns, which meant independency of their family. But it also meant that they became part of the modern city. But it is important to be aware of the differences between married and unmarried women. The unmarried were emancipated and received the same opportunity as men, but married women had lo be different from men in every direction. But even if their role was supposed to be traditionel, demografic changes (concerning the marriage pattern, fertility and death) revolutionized the life-cycles of women. This development also had political importance.

Med hjälp av psykoanalytisk teori tolkas kvinnor på vita duken alltid som objekt. För att hitta ett kvinnligt subjekt krävs helt andra verktyg. Feministiska forskare har framför sig en angelägen uppgift att ge kvinnorna en plats i filmhistorien - både som åskådare och upphovspersoner. Vem är förresten "författaren " till den filmiska texten ? Ar det regissören - som nästan alltid är en man? Eller är det producenten, manusförfattaren eller författaren till boken som filmen bygger på?

Published: June 2022

The rapid development in the field of information technology has provided significant benefits to both society and the business world. There are numerous ethical challenges that computer users must deal with. These include violation of intellectual property, hacking, invasion of privacy, honesty, secrecy, loyalty, accountability, and responsibility. Situational and individual characteristics influence information systems employees' behavioral intentions to act ethically. The situational variables that affect employee ethical behavior and financial losses can be controlled and influenced by organizations to determine and control employee ethical conduct and financial losses. Ethics-related losses caused by information systems employees can be successfully resolved by incorporating the code of ethics into the code of professional conduct and employee contract, incorporating ethics into organizational culture, designing rewards for ethical behavior and severe punishments for unethical behavior, and incorporating ethics into the code of professional conduct and employee contract.

Published: June 2022

Radiotherapy has become one of the promising modalities in cancer treatment either as primary or in combination with other forms of therapy. But is also associated with a number of short and long term adverse effects such as pain, mucositis, erythema, ulceration, soft tissue necrosis, altered taste /olfaction, edema, radiation induced fibrosis, trismus, dysphagia, radiation caries, salivary gland dysfunction and Osteoradionecrosis. In almost every case, the adjacent normal tissue also gets irradiated because of its close proximity and worsens the scenario. Hence, their tissue tolerance exceeds, which leads to cell injury and a vicious cycle of adverse effects follows. Radiation stents can be a boon in sparing the adjacent tissues. This literature review summarizes the evidence which suggest actual reduction of adverse effects due to decline in levels of radiation in adjacent tissues.
DATAISM AS A NEW FORM OF POLITICS
Authors: BULUR Neslihan
Published: June 2022

Today, when big data technology has made great progress, it is discussed whether digital technologies can be used as a mechanism for social benefit that exceeds human will. The development that forms the basis of these discussions is algorithms and artificial intelligence technologies. The fact that our entire lives are connected to the internet reveals the possibility that algorithms that know us better than ourselves can make better predictions for both individuals and the benefit of society. On the other hand, there are also hesitations that the existence of technology as a technical infrastructure will encompass the whole society as a social benefit. The purpose of this study is to discuss whether algorithms will further marginalize existing unequal social relations at the point of social benefit or will they build an ideal social order as the philosophy of dataism advocates. For this purpose, in the first part of the study, the new power technique that neoliberalism emerged with the developing technology and the effect of this technique on people's consciousness were emphasized. The first part provides a basis for the purpose of the study, as the power techniques also give a clue about the way politics is implemented. In the second part of the study, it is questioned how the philosophy of dataism, which approaches the sovereignty of algorithms from a cyber-utopian perspective, will change the way of doing politics. In the conclusion and discussion part, algorithms are evaluated in the context of politics, human will and social benefit. The study is an evaluation article and is based on theoretical analysis.

Published: June 2022

Atualmente, o diabetes mellitus é a doença endócrina mais prevalente em todo o mundo. Segundo o atlas de 2019 da IDF (International Diabetes Federation), estima-se uma prevalência mundial de 463 milhões de indivíduos diabéticos, considerando a faixa etária entre 20 a 79 anos. Destes, cerca de 90% correspondem a portadores de diabetes mellitus tipo 2 e cerca de metade (50,1%) desconhece o diagnóstico. Diversos estudos têm demonstrado que a prevenção e educação em diabetes é uma poderosa ferramenta para reduzir a incidência crescente desta doença e reduzir o impacto desta patologia a longo prazo, tanto na qualidade de vida como na manifestação de complicações crônicas, além de reduzir gastos de saúde pública. Neste trabalho, procuramos avaliar o conhecimento do paciente diabético e sua influência no controle glicêmico e na evolução natural da doença.

Investigation of the Effect of Cutting Directions On the Improvement of Mechanical Parameters of Treated Cork by THT: Experimental Measurement, Modelling and Optimization of Mass Transfer
Authors: ZEMIRLINE Abdelkrim , KERMEZLI Tayeb , ANNOUN Mohamed , DOUANI Mustapha
Published: June 2022

This work aims to investigate the impact of the cutting direction on the transfer properties of both the native cork and the treated by an optimized cycle at high temperature and boiling for the purpose to improve its mechanical characteristics in all three orthotropic directions. The study of the insulation performance is based on tracking the apparent mass diffusion coefficient (Dapp) variation in order to evolve a new material with the thermal, mass, acoustic and vibratory properties needed for various applications. TGA, IR and SEM analyzes are used to confirm the enhancement of the treated cork. The Dapp of the diffusing chemical species, NaCl (0.7M), is determined by conductimetric method. In transient mode, a mathematical model of mass transfer, which includes the diffusion parameters of the chemical species, is developed. Through the calibration of the model with the experimental measurements the Dapp values ​​were determined and then refined numerically by optimization using the Bat-Algorithm. The obtained results showed that the treatment improves the diffusion property of the native (DN) compared to the treaty (DA) with the values in the order of 10-12 and 10-13 m2.s-1 respectively with a relative uncertainty of 10-7. In addition, this investigation reveals that the radial diffusion coefficient (DR) is significantly higher than the tangential diffusion (DT) and longitudinal (DL) diffusion coefficients which both are almost of the same.
Multiscale Analysis of the Performance of Micro/nano Porous Filtration Membranes with Double Concentric Cylindrical Pores: Part I-Analysis Development
Authors: TANG Zhipeng , ZHANG Yongbin
Published: June 2022

In nanoporous filtration membranes, when the radius of the filtration pore is so big that the flow of the adsorbed layer on the pore wall is comparable with the flow of the continuum fluid in the central region of the pore, the multiscale analysis is required for estimating the performance of the membranes. The present paper presents such a multiscale analysis for the performance of nanoporous filtration membranes with double concentric cylindrical pores. The dimensionless flow resistance of the membrane was calculated for a weak fluid-pore wall interaction for varying operational parameter values. It was found that there is the optimum ratio of the radius of the filtration pore to the radius of the other bigger pore for the highest flux of the membrane.
Multiscale Analysis of the Performance of Micro/nano Porous Filtration Membranes with Double Concentric Cylindrical Pores: Part II-Optimization Results
Authors: TANG Zhipeng , ZHANG Yongbin
Published: June 2022

The multiscale calculation results for the values of the optimized parameters are presented for the micro/nano porous filtration membranes with double concentric cylindrical pores where multiscale flows occur. For a weak liquid-pore wall interaction, the optimum ratio of the radius of the bigger pore to the radius of the smaller pore (i.e. the filtration pore) can be calculated from the classical equation, however the corresponding lowest flow resistance of the membrane should still be calculated from the multiscale analysis owing to the adsorbed layer effect when the ratio Landax of the thickness of the adsorbed layer to the radius of the smaller pore is greater than 0.1. For medium and strong liquid-pore wall interactions, the optimum ratios of the pore radii should be calculated from the multiscale analysis, and the corresponding lowest flow resistances of the membrane are much higher than the classical calculation showing the significant effect of the adsorbed layer when Landax>=0.1.
Ontology for the User-Learner Profile Personalizes the Search Analysis of Online Learning Resources
Authors: Kordahi Marilou
Published: June 2022

We hope to contribute to the field of research in information technology and digital libraries by analyzing the connections between Thematic Digital Universities and digital user-learner profiles. Thematic Digital Universities are similar to digital libraries, and focus on creating and indexing open educational resources, as well as improving learning in the information age. The digital user profile relates to the digital representation of a person’s identity and characteristics. In this paper we present the design of an ontology for the digital User-Learner Profile (OntoULP) and its application program. OntoULP is used to structure a user-learner’s digital profile. The application provides each user-learner with tailor-made analyses based on informational behaviors, needs, and preferences. We rely on an exploratory research approach and on methods of ontologies, user modeling, and semantic matching to design the OntoULP and its application program. Any user-learner could use the OntoULP and its application program.

Contactless services have become a common way for public libraries to provide services. As a result, the strategy used by public libraries in China will effectively stop the spread of epidemics caused by human touch and will serve as a model for other libraries throughout the world. The primary goal of this study is to gain a deeper understanding of the contactless service measures provided by large Chinese public libraries for users in the pandemic era, as well as the challenges and countermeasures for providing such services. The data for this study was obtained using a combination of website investigation, content analysis, and telephone interviews for an analytical survey study of 128 large public libraries in China. The study finds that touch-free information dissemination, remote resources use, no-touch interaction self-services, network services, online reference, and smart services without personal interactions are among the contactless services available in Chinese public libraries. Exploring the current state of contactless services in large public libraries in China will help to fill a need for empirical attention to contactless services in libraries and the public sector. Up-to-date information to assist libraries all over the world in improving their contactless services implementation and practices is provided.

Fascismo e grande capital
Authors: Guérin Daniel
Published: June 2022

Fascismo e grande capital é um clássico. Publicado em 1936, foi editado e reeditado em diversos países. No Brasil, permanecia inédito. O autor viajara pela Alemanha nazista e escrevera um livro relatando essa viagem. Impressionada com a qualidade do material, uma companheira o incitou a fazer uma pesquisa sistemática sobre o tema. O resultado foi este livro repleto de ideias, de teses originais e também de tratamento mais fundamentado e desenvolvido para teses que já circulavam sobre o fascismo. O objetivo de Fascismo e grande capital é elaborar o conceito de fascismo. Para tal elaboração conceitual, o autor examina o fascismo na Itália e na Alemanha. Guérin apresenta o fascismo como um movimento pequeno-burguês e de classe média, reacionário, que, numa conjuntura determinada, é cooptado pela burguesia e, particularmente, pela grande burguesia, que disputa a hegemonia política com o médio capital. O livro de Daniel Guérin, tratando de fenômeno aparentemente tão distante, contribui para a compreensão da natureza da extrema direita no mundo contemporâneo. (Armando Boito Jr.)
Modulation of topological phase transitions and topological quantum states in one-dimensional superconducting transmission line cavities lattice
Authors: Wang Wei , Wang Yi-Ping ,   College of Science, Northwest A&F University, Yangling 712100, China
Published: June 2022

We propose a theoretical scheme for a one-dimensional lattice based on a superconducting quantum circuit system consisting of two types of superconducting microwave cavities, the interaction between nearest-neighbor and next-nearest-neighbor unit cells that can be adjusted by the magnetic flux, the system can obtain the collective dynamic evolution and study the topological properties of the system.First, we investigate the energy spectrum and edge states of the odd-even lattice size and find that the odd-even lattice number affects the topological properties of the system. Furthermore, considering the next-nearest interactions, it is found that there are constraints on the next-nearest interactions, which can be tuned to study the topological phase transitions of the system and the transfer of topological quantum states.In addition, considering the influence of defects on topological properties, it is found that the defect potential energy is small, the system energy band is stable, the edge states remain unchanged, and the energy spectrum fluctuation is small and distinguishable. Conversely, the energy band distribution is destroyed, it will become disordered and chaotic. The research results can design some new quantum devices for quantum optics and quantum information processing.

Diamond/graphene composite three-dimensional electrode has attracted extensive attention because of its low background current, wide potential window from diamond component, and high electrochemical activity from graphite component. In this work, by using the hot wire chemical vapor deposition method, nano diamonds are embedded in the vertical graphene sheet on the surface of single particle layer of nano diamond by regulating the short-term growth time to form a composite three-dimensional electrode. The results show that the electrode exhibits a wide potential window (3.59 V) and a very low background current (1.27 mA/cm2) when nano-diamond crystals grow on the top of the vertical graphene sheet. The composite structure of nano-diamond crystals coated with graphite on the top of the graphene sheet is the key to broadening the potential window and reducing the background current. With the increase of growth time, the vertical graphene sheet grows and nano-diamond grains are embedded into the lamellae, and a novel nano-diamond/graphene composite vertical lamellae structure is constructed. The ordered graphite structure increases the electrochemical active area to 677.19 μC/cm2 and the specific capacitance to 627.34 μF/cm2. The increase of graphite components makes the potential window narrow, and the embedded nano-diamond crystals effectively reduce the background current. This study provides a new method for preparing three-dimensional nanodiamond/graphene composite electrodes by hot wire chemical vapor deposition, and provides a new idea for fully exploiting the synergistic effect of diamond/graphene composite films.
Influence of driving-laser wavelength on emission of high-order harmonic wave generated by atoms irradiated by ultrashort laser pulse

Published: June 2022

With the numerical solution of the time-dependent Schrodinger equation, we theoretically investigate the high-order harmonic emissions generated by the atoms irradiated by the ultrashort lasers with different wavelengths but the same pondermotive energy. As the driving-laser wavelength increases, the intensity of the high-harmonic emission decreases. Comparing with the harmonic spectra of atoms driven by a 1000-nm-wavelength laser pulse, a new peak structure appears in the spectra of atoms driven by a 5000-nm-wavelength laser wavelength. It is shown by the time-frequency analysis of the harmonic emission, the time-dependent evolution of the electron density, and the time-dependent population analysis of the eigenstate, that the physical mechanism behind the new peak appearing in the harmonic spectra is the interference between the harmonic emission generated by the electrons ionized out of the excited atoms returning to the parent ions and the harmonic emissions resulting from the ground state ionization.

It is found that the imaginary potential leads the imaginary energy spectra to appera in the topologically nontrivial region of this system, and the \begin{document}${\cal {PT}}$\end{document} phase transition to happen in the topologically trivial region. In addition, the imaginary potential energy and spin-orbit coupling work together to make the topological phase transition occur in the topologically trivial region, and the topological non-trivial region becomes wider. The energy spectrum results show that the imaginary potential energy and the spin-orbit coupling can obviously control the zero-energy states of the system, which mainly lies in the presence of four zero-energy states with four different localities and numbers. This shows the special adjustment effect of imaginary potential energy and spin-orbit coupling on the energy band structure of the system. It is believed that these results are helpful in understanding the topological phase transition behavior of \begin{document}${\cal {PT}}$\end{document}-symmetric non-Hermitian system.

Combining with in situ nanomechanical testing system and video module of scanning electron microscope, the nanoindentation testing is performed to study the peeling-tearing behavior of two-dimensional material van der Waals heterostructures. After two-dimensional MoS2 nanosheets prepared by chemical vapor deposition are assembled into MoS2/SiO2 heterostructures by wet transfer, the nanoindentation is carried out by manipulating the tungsten probe in the in situ nanomechanical testing system. When the tungsten probe is tightly indenting into MoS2 nanosheets, a new W/MoS2/SiO2 heterostructure is assembled. With the tungsten probe retracting, the adhesive effect makes the two-dimensional MoS2 nanosheet peel off from SiO2/Si substrate to form a bulge. After reaching a certain height, under the van der Waals adhesion interaction, an incomplete penetration fracture occurs along the arc line contacting the needle. Then cleavage appears and produces two strip cracks and MoS2/SiO2 interface separation takes place simultaneously, before a large area of MoS2 nanosheet is teared. Based on the density functional theory calculation of interface binding energy density of van der Waals heterogeneous interface, the interface binding energy density of MoS2/W is verified to be larger than that of MoS2/SiO2, which explains the adhesion peeling behavior of MoS2 induced by van der Waals force between heterogeneous interfaces, perfectly. By using the peeling height and tearing length of MoS2 recorded by video module, the fracture strength of MoS2 is obtained to be 27.055 GPa and stress-strain relation can be achieved according to the film tearing model. The density functional theory simulation results show that the fracture strength of MoS2 is in a range of 21.7–32.5 GPa, and the stress-strain relation is consistent with the experimental result measured based on film tearing model. The present work is expected to play an important role in measuring the fracture strengths of two-dimensional materials, the assembly, disassembly manipulation and reliability design of two-dimensional materials and van der Waals heterostructures devices.

Tuberculosis (TB), caused by Mycobacterium tuberculosis (M. tb), is a leading cause of death due to infectious disease. TB is not traditionally associated with biofilms, but M. tb biofilms are linked with drug and immune tolerance and there is increasing recognition of their contribution to the recalcitrance of TB infections. Here, we used M. tb experimental evolution to investigate this complex phenotype and identify candidate loci controlling biofilm formation. We identified novel candidate loci, adding to our understanding of the genetic architecture underlying M. tb biofilm development. Under selective pressure to grow as a biofilm, regulatory mutations rapidly swept to fixation and were associated with changes in multiple traits, including extracellular matrix production, cell size, and growth rate. Genetic and phenotypic paths to enhanced biofilm growth varied according to the genetic background of the parent strain, suggesting that epistatic interactions are important in M. tb adaptation to changing environments.

Cancer’s genomic complexity is gradually increasing as we learn more about it. Genomic classification of various cancers is crucial in providing oncologists with vital information for targeted therapy. Thus, it becomes more pertinent to address issues of patient genomic classification. Prostate cancer is a cancer subtype that exhibits extreme heterogeneity. Prostate cancer contributes to 7.3% of new cancer cases worldwide, with a high prevalence in males. Breast cancer is the most common type of cancer in women and the second most significant cause of death from cancer in women. Breast cancer is caused by abnormal cell growth in the breast tissue, generally referred to as a tumour. Tumours are not synonymous with cancer; they can be benign (noncancerous), pre-malignant (pre-cancerous), or malignant (cancerous). Fine-needle aspiration (FNA) tests are used to biopsy the breast to diagnose breast cancer. Artificial Intelligence (AI) and machine learning (ML) models are used to diagnose with varying accuracy. In light of this, we used the Genetic Folding (GF) algorithm to predict prostate cancer status in a given dataset. An accuracy of 96% was obtained, thus being the current highest accuracy in prostate cancer diagnosis. The model was also used in breast cancer classification with a proposed pipeline that used exploratory data analysis (EDA), label encoding, feature standardization, feature decomposition, log transformation, detect and remove the outliers with Z-score, and the BAGGINGSVM approach attained a 95.96% accuracy. The accuracy of this model was then assessed using the rate of change of PSA, age, BMI, and filtration by race. We discovered that integrating the rate of change of PSA and age in our model raised the model’s area under the curve (AUC) by 6.8%, whereas BMI and race had no effect. As for breast cancer classification, no features were removed.

Massive multiple-input multiple-output (massive-MIMO) is considered as the key technology to meet the huge demands of data rates in the future wireless communications networks. However, for massive-MIMO systems to realize their maximum potential gain, sufficiently accurate downlink (DL) channel state information (CSI) with low overhead to meet the short coherence time (CT) is required. Therefore, this article aims to overcome the technical challenge of DL CSI estimation in a frequency-division-duplex (FDD) massive-MIMO with short CT considering five different physical correlation models. To this end, the statistical structure of the massive-MIMO channel, which is captured by the physical correlation is exploited to find sufficiently accurate DL CSI estimation. Specifically, to reduce the DL CSI estimation overhead, the training sequence is designed based on the eigenvectors of the transmit correlation matrix. To this end, the achievable sum rate (ASR) maximization and the mean square error (MSE) of CSI estimation with short CT are investigated using the proposed training sequence design. Furthermore, this article examines the effect of channel hardening in an FDD massive-MIMO system. The results demonstrate that in high correlation scenarios, a large loss in channel hardening is obtained. The results reveal that increasing the correlation level reduces the MSE but does not increase the ASR. However, exploiting the spatial correction structure is still very essential for the FDD massive-MIMO systems under limited CT. This finding holds for all the physical correlation models considered.
Research Competency among Elementary School Teachers: An evaluative assessment for School-Based Action Research (SBAR)

Teachers have been challenged to become professionally productive through research outputs. DepEd Memorandum no.114 s. 2014 mandated the teachers to conduct action research or assessment within their realm. A yearly congress for School-Based Action Research (SBAR) was done. However, the lack of research output remains a problem in every school district. This study aimed to determine the level of research competency among the elementary school teachers in Makilala West and Makilala Central Districts, Cotabato Division. Anchored on Corey's Theory on Curriculum Development and Research and Lewin's Theory on Research, this study employed a mixed method design. On the quantitative strand, 114 elementary classroom teachers were the respondents while 16 schools participated in the qualitative strand of the study. Following the merging of the data, the quantitative and qualitative data showed divergence. Results revealed that the respondents were moderately competent in research. Digging on the problems encountered by the teachers for not conducting any research activity, the findings exposed that the poor background of teachers in research, the problem on schedule, overlapping of activities, and too much administrative work were the reasons behind their failure to submit their research output. To aid teachers in the preparation of scholarly research, an intervention plan was made.
