CHALLENGES ENCOUNTERED AND STRATEGIES EMPLOYED IN MANAGING STUDENTS’ BEHAVIOR OF JUNIOR HIGH SCHOOL TEACHERS OF A PRIVATE SCHOOL IN QUEZON PROVINCE
Authors: LINGON GARRY
Published: September 2019

This
study determined and analyzed the challenges encountered and strategies
employed by Junior High School Teachers in managing the students' behavior, who
were the respondents of the study, in a private school in Quezon Province that
gave way to the creation of a Teachers' Guidebook on Managing the Students'
Behavior as an output. The descriptive-evaluative method of research was used
in the study together with the Weighted Arithmetic Mean (WAM) as the
statistical tool. Further, a validated researcher-made instrument was used to
gather the needed data in the study.
 Based on the findings of the study,
under the code of conduct related to discipline, the respondents revealed the
challenges encountered in managing students' behavior. The statements that got
the highest WAM rating were (1) Failure of students to wear their uniform in
official activities held inside or outside the school; (2) Students forget
their ID at Home; and, (3) Failure of the students to accomplish their excuse
slip form.

 In addition, the code of conduct
related to decorum, the following are some of the challenges encountered by the
respondents: (1) Students do not maintain silence when no teacher is around;
(2) Students fight with their classmates when they lose their temper; (3)
Students disrespect the sacredness of the chapel by uttering nasty words inside
the place; (4) Students ignore teacher’s instructions and do some foolishness
with their friends; (5) Students disobey the rules and regulations of the
school; (6) Students are buying foods even though it is not a break time; (7) Students fail to maintain silence
inside the library; (8) Students do not observe silence while buying in the
cafeteria; (9) Students do not participate in the mass instead they talk to
their classmate; and, (10) Students talk
with their classmate while flag ceremony is on-going.

 The
findings of the study revealed that the orientation of the students was needed
to familiarize the students on the rules and regulations implemented in the
school and to consistently impose discipline.

 The
following recommendations are made by the researcher: The students should
understand fully the importance of following the school's rules and regulations
by taking seriously the identified school policy on the code of conduct. The teachers should conduct an annual
orientation/re-orientation program that emphasizes the findings of this
research, and seriously consider more effective strategies to overcome problems
on code of conduct and use the output of this study. The school administrators
should issue a school memorandum requiring all teachers and school staff to
strictly implement the school policies. The future researchers should make a
study on the assessment of the quality of the school policies implemented in
the private schools in Quezon Province.

The Theory of Unitrons - A Classical Physical Approach for Fundamental Particles and Forces
Authors: Forster Tibor
Published: September 2019

This fundamentally new conception is a candidate for the Theory of Everything. According to this classical physical approach, all elementary particles are electric multipole composite and made up of smaller, fundamental building blocks named unitrons. The unitron is the ultimate constituents of matter with an invariable mass, spatial extension and positive (u+) or negative (u-) electric charge. There is only one fundamental interaction between unitrons: the attractive or repulsive electric force, which corresponds to the macroscopically described Coulomb force. The model can explain the electric, magnetic, gravitational and nuclear forces furthermore the inertia and inertia forces as the manifestation of the attractive and repulsive fundamental forces of unitrons. The fundamental force propagates at speed of light. It holds the elementary particles together and determines their motion too. Every elementary particle contains both positively and negatively charged unitrons; their net charge is a resultant charge of unitrons. The elementary particles can be described as electromagnetic gyroscopes. The electromagnetic radiation is a wave-like change in the electromagnetic field generated by the electromagnetic force of a photon spinning around its axis. The energy of a photon is proportional to its rotational frequency. Only this rotational frequency changes when it is absorbed or emitted.
On how religions could accidentally incite lies and violence: Folktales as a cultural transmitter
Authors: Vuong Quan-Hoang , La Viet-Phuong , Ho Tung Manh , Nguyen Hong-Kong T. , Vuong Thu-Trang , Hanh Vu Thi , Nguyen Minh-Hoang , Ho Manh-Toan
Published: September 2019

This research employs the Bayesian network modeling approach, and the Markov chain Monte Carlo technique, to learn about the role of lies and violence in teachings of major religions, using a unique dataset extracted from long-standing Vietnamese folktales. The results indicate that, although lying and violent acts augur negative consequences for those who commit them, their associations with core religious values diverge in the final outcome for the folktale characters. Lying that serves a religious mission of either Confucianism or Taoism (but not Buddhism) brings a positive outcome to a character (βT_and_Lie_O= 2.23; βC_and_Lie_O= 1.47; βT_and_Lie_O= 2.23). A violent act committed to serving Buddhist missions results in a happy ending for the committer (βB_and_Viol_O= 2.55). What is highlighted here is a glaring double standard in the interpretation and practice of the three teachings: the very virtuous outcomes being preached, whether that be compassion and meditation in Buddhism, societal order in Confucianism, or natural harmony in Taoism, appear to accommodate two universal vices—violence in Buddhism and lying in the latter two. These findings contribute to a host of studies aimed at making sense of contradictory human behaviors, adding the role of religious teachings in addition to cognition in belief maintenance and motivated reasoning in discounting counterargument.

A survey on the role of deck officers with experience of ship operations in ice-covered waters - training aspects
Authors: Southwell Natacha
Published: September 2019

A continued multidecadal decline in sea-ice extent has led to the opening up of the polar regions to emerging maritime opportunities. In spite of this decline, extreme variability in ice, temperature and weather conditions remains a significant navigational challenge to mariners. Thus, the emerging opportunities for increased maritime operations in the polar regions present significant safety and environmental risks. As such, seafarers with ice navigation expertise is a necessity for polar operations. An exploratory study was carried out into contemporary navigation skills in ice-covered waters worldwide, with a focus on current training requirements, knowledge and skills required for safe polar operations, This poster only presents the findings on training aspects of the survey.
Generics designate kinds but not always essences
Authors: Noyes Alexander , Keil Frank
Published: September 2019

People believe that some categories are kinds with reliable causal structure and high inductive potential (e.g., Tigers). Widely endorsed theories propose that people are biased to assume kinds are essential, and so naturally determined by internal causal properties. Generic language (e.g., “Men like sports”) is one mechanism thought to evoke this bias. We propose instead that generics principally designate that categories are kinds. Participants can entertain diverse causal structures in the presence of generics: Hearing that biological properties generalize to a category (e.g., “Men grow beards”) prompts participants to infer essential structure, but hearing neutral or social properties (“Women are underpaid”) generalize prompts other causal beliefs. Thus, generics induce essentialism only in in interaction with cues that reasonably prompt essentialist explanation. We tested our model with adult participants (N = 739 total), using measures that disentangle essentialist beliefs from kind beliefs. In Study 1, we replicate prior methods with our new measures, and find that generics influence kind beliefs more than essentialism. In Study 2, we vary property content (biological vs. cultural properties), and show that generics only increase essentialism when paired with biological properties. In Study 3, we show that generics designate kinds but not essentialism when neutral properties are used across animals, tools, and people. In Study 4, we show that believing a category is a kind increases the spontaneous production of generic statements, regardless of whether the kind is essential or socially constructed. Generics do not necessitate essentialist beliefs. Participants were flexible in their reasoning about kinds.
Therapist Guided Activity Practice for Depressive Symptoms in University Students: A Randomized Controlled Trial
Authors: Stein Aliza , Shumake Jason , Beevers Christopher G , Smits Jasper A. J.
Published: September 2019

Behavioral activation (BA) interventions are efficacious for depression, yet a substantial minority of patients do not respond to treatment. Strategies that facilitate activity outside of session may improve BA treatment outcomes. The objective of the current study was to examine whether briefly practicing a target activity (guided practice) during a modified single session of BA resulted in higher homework completion compared to activity planning alone (control). Participants (n=100) were college students with depressive symptoms. All participants selected an activity to monitor for 7 days with a goal of completing the activity 5 times. Self-report questionnaires were completed at baseline and 7-days later. Contrary to our hypothesis, participants assigned to the guided practice condition did not evidence a greater improvement in self-efficacy for completing the targeted activity relative to the control condition. However, there was a positive effect of guided practice on activity completion. Participants assigned to the guided practice condition evidenced a higher rate of activity completion relative to those assigned to the control condition. These results support the utility of guided practice as a strategy for improving homework compliance in BA.
Activating episodic simulation increases affective empathy
Authors: Vollberg Marius C. , Gaesser Brendan , Cikara Mina
Published: September 2019

Affective empathy, feeling what others feel, is a powerful emotion that binds us to one another. Here we ask whether how we mentally represent the scene in which another suffers informs our emotions. For example, when we learn about someone suffering outside of the here and now, such as a refugee devastated by violence or famine, does a manipulation potentiating our ability to simulate the scene around the victim heighten our empathic response? Expanding recent advances in the memory literature, we investigate the link between activating our ability to imagine events—episodic-simulation—and empathy for in-group and out-group members in a series of online and laboratory studies (N = 1010). Incidental manipulations of episodic-simulation, unrelated in content and structure to the empathy judgment task, increased overall empathy for both in-group as well as out-group members. Critically, this relationship was mediated by participant-generated episodic detail of the victim’s surroundings
Speech-in-noise recognition and the relation to vocal pitch perception in adults with autism spectrum disorder and typical development
Authors: Schelinski Stefanie , von Kriegstein Katharina
Published: September 2019

We tested the ability to recognise speech-in-noise and its relation to the ability to discriminate vocal pitch in adults with high-functioning autism spectrum disorder (ASD) and typically developed adults (matched pairwise on age, sex, and IQ). Typically developed individuals understood speech in higher noise levels as compared to the ASD group. Within the control group but not within the ASD group, better speech-in-noise recognition abilities were significantly correlated with better vocal pitch discrimination abilities. Our results show that speech-in-noise recognition is restricted in people with ASD. We speculate that perceptual impairments such as difficulties in vocal pitch perception might be relevant in explaining these difficulties in ASD.
Institutional actors: Children’s emerging beliefs about the causal structure of social roles
Authors: Noyes Alexander , Keil Frank , Dunham Yarrow
Published: September 2019

Institutions make new forms of acting possible: Signing executive orders, scoring goals, and officiating weddings are only possible because of the U.S. government, the rules of soccer, and the institution of marriage. Thus, when an individual occupies a particular social role (President, soccer player, and officiator) they acquire new ways of acting on the world. The present studies investigated children’s beliefs about institutional actions, and in particular whether children understand that individuals can only perform institutional actions when their community recognizes them as occupying the appropriate social role. Two studies (Study 1, N = 120 children, 4-11; Study 2, N = 90 children, 4-9) compared institutional actions to standard actions that do not depend on institutional recognition. In both studies, 4- to 5-year-old children believed all actions were possible regardless of whether an individual was recognized as occupying the social role. In contrast, 8- to 9-year-old children robustly distinguished between institutional and standard actions; they understood that institutional actions depend on collective recognition by a community.
The value of communication: Evidence from a field experiment with entrepreneurs in Togo
Authors: Dimitriadis Stefan , Koning Rembrand
Published: September 2019

Why do some entrepreneurs benefit from their portfolio of peer advisers while others do not? In this study, we argue that communication practices are an important but overlooked factor in the formation of useful advice relationships between entrepreneurs, particularly in the context of developing economies. We hypothesize that improving entrepreneurs’ communication practices will affect the relationships they form and have implications for their business performance. To test our theory, we conducted a field experiment in Togo with 301 entrepreneurs who were randomized into a communication practices intervention that was embedded in a business training program. We found that entrepreneurs who were exposed to better communication practices perceived interactions more cooperatively and exchanged more information during those interactions. Moreover, improving communication practices also led to a 50 percent increase in the number of relationships entrepreneurs formed with peers. These relationships exhibited more matching based on skill and were more ethnically diverse. Finally, communication practices training also substantially increased entrepreneurs’ business performance. Our findings highlight how communication practices play a central role in entrepreneurs’ ability to form portfolios of relationships and perform in challenging business environments.
The visible hand of research performance assessment
Authors: Hamann Julian
Published: September 2019

Far from allowing a governance of universities by the invisible hand of market forces, research performance assessments do not just measure differences in research quality, but yield themselves visible symptoms in terms of a stratification and standardization of disciplines. The article illustrates this with a case study of UK history departments and their assessment by the Research Assessment Exercise (RAE) and the Research Excellence Framework (REF), drawing on data from the three most recent assessments (RAE 2001, 2008, REF 2014). Symptoms of stratification are documented by the distribution of memberships in assessment panels, of research active staff, and of external research grants. Symptoms of a standardization are documented by the publications submitted to the assessments. The main finding is that the RAEs/REF and the selective allocation of funds they inform consecrate and reproduce a disciplinary center that, in contrast to the periphery, is well-endowed with grants and research staff, decides in panels over the quality standards of the field, and publishes a high number of articles in high-impact journals. This selectivity is oriented toward previous distributions of resources and a standardized notion of “excellence” rather than research performance.
Computer-Cognition Interfaces: Sensing and influencing mental processes with computer interaction
Authors: Mottelson Aske
Published: September 2019

The variety of information about users hidden in the details of interaction data is increasingly being utilized for recognizing complex mental processes. Digital systems can correspondingly influence mental processes of users, paving the way for new interactive systems that interface with the human mind. This thesis presents advances to such interfaces: through four papers I show how human affect and cognition can be sensed and influenced computationally.Paper 1 presents two studies that together show that affect influences mobile interaction, which allows for binary discrimination between neutral and positive affect using sensor led machine learning classification. Paper 2 builds upon the methods presented in Paper 1 and extends the classification domain to dishonesty, also using mobile interaction data. The paper shows across three studies how dishonesty and honesty vary in interactional details, and how this difference can be utilized for estimating the veracity of user behavior based on features that are engineered by mobile interaction data.Paper 3 presents a feasibility study of conducting virtual reality studies outside a laboratory, to increase heterogeneity and power. The paper shows through two studies how a range of VR tasks can be conducted without the use of an immediate experimenter, with participants carrying out experiments themselves. In Paper 4 I apply this methodology, and conduct a VR study with more than 200 participants to study how manipulations to avatars can influence affect responses. The paper presents evidence supporting the link between affect and avatars, and additionally discusses the interplay between positive affect and body ownership.

The financial crisis is a condition where a country's finances experience a disruption which is characterized by a drastic increase in the inflation rate, a weakening currency exchange rate, and a decrease in other economic activities. Indonesia experienced financial crises in 1997 and 1998 which resulted in a collapse of financial conditions and national stability. Therefore, it is necessary to have a model to find out the crisis, so that efforts to recover the impact of the crisis can be done as early as possible from the model. This study aims to apply the Markov Switching Error Correction Model to detect a crisis. Based on the indicator of real deposit interest rates it can be concluded that the MS-ECM can explain the crisis that occurred in mid-1997 and late 2005

Published: September 2019

Agricultural products are types of products that have disadvantages, among others: perishable and short shelf life, especially for horticulture. These weaknesses cause horticultural products to require special treatment from pre-harvest to post-harvest so that the quality does not decrease. A decrease in product quality will affect its sale value in the market. However, special handling requires additional costs, so the amount of post-harvest handling must also consider the demand of the buyer.This research aims to find out and understand the best storage treatment for fruits and vegetables to maintain the physical condition of the products and marketing strategies in traditional and modern markets.Based on the results of research shows that most of the people of Serang City tend to prefer shopping in traditional markets, but most also choose to shop in traditional and modern markets, in their opinion it can be concluded that if they shop at traditional markets they can bargain from prices that have been set and they can also directly, whereas if in the modern market they can only see the prices available on the desired goods.
Crash Injury Analysis of Knee Joint Considering Pedestrian Safety
Authors: Asgari M , Keyvanian Sh S
Published: September 2019

Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pedestrian accidents and to predict the effect of parameters such as collision speed and height due to the car speed and bumper height on knee joint injuries, especially in soft tissues such as ligaments, cartilages and menisci.Methods: A 3D finite element (FE) model of human body knee joint is developed based on human anatomy. The model consists of femur, tibia, menisci, articular cartilages and ligaments. Material properties of bones and soft tissues were assumed to be elastic, homogenous and isotropic.Results: FE model is used to perform injury reconstructions and predict the damages by using physical parameters such as Von-Mises stress and equivalent elastic strain of tissues.Conclusion: The results of simulations first show that the most vulnerable part of the knee is MCL ligament and second the effect of speed and height of the impact on knee joint. In the critical member, MCL, the damage increased in higher speeds but as an exception, smaller damages took place in menisci due to the increased distance of two bones in the higher speed.

Authors: Perdomo Mauro Andrés , Armand Ugon Gustavo , Sciuto Pablo , Ferreira Martín , González Daniel
Published: September 2019

Introducción

 El abordaje laparoscópico para hernioplastias inguinales requiere un conocimiento exhaustivo de la anatomía posterior de la región, distinto al utilizado para los procedimientos por vía anterior. Esto supone un desafío para los cirujanos.

 Descripción de contenidos

 En el video se presenta la correlación entre el modelo cadavérico y el procedimiento laparoscópico de la hernioplastia transabdominal preperitoneal (TAPP), identificando las estructuras que permiten la realización de un procedimiento seguro. Se presenta el concepto de  visión crítica de seguridad del orificio miopectíneo de Fruchaud y la técnica utilizada en nuestro servicio.

 Observaciones y comentarios

 La reparación laparoscópica de las hernias inguinales es técnicamente más demandante que el procedimiento de Lichtenstein (hasta ahora gold standard) con una curva de aprendizaje más larga y mayor número de complicaciones. Por lo tanto resulta fundamental la utilización de recursos a que favorezcan la familiarización con la anatomía y técnica quirúrgica, entre ellos el material cadavérico.
Non-equilibrium thermodynamics and stoichiography in studying solid-phase preparation processes of functional materials
Authors: Malakhov V. V. , Parmon V. N.
Published: September 2019

The application of the general principles of the non-equilibrium thermodynamics and stoichiography allows obtaining novel information on the solid-phase transformations happening in multielement and heterophase substances and materials. Without the solid-phase standards, the use of stoichiography allows detecting, identifying and quantitative determining known and unknown crystalline and amorphous phases being of constant or variable composition. For the first time, reliable results concerning evolution of solid products during preparation of the Mo-V-Te-Nb-O catalyst of propane ammoxidation are presented.
Origin, sites and mobility of helium and argon isotopes in meliphanite

Published: September 2019

The similarity of U-Th-4He age of meliphanite and the age of regional metamorphism (1800 Ma) seems to indicate a good retention of radiogenic 4He in the mineral, but contradicts with the experience of U-Th-4He dating. To analyze this result 3He concentration was measured, which appeared to be very low, about 2 % of the totally produced 3He. Radiogenic 3,4He isotopes occupier radiation tracks. Intersections of these tracks with cleavage planes provide migration of He atoms from the mineral and 4He, produced due to U and Th decay, should be almost completely lost. Instead, meliphanite contains trapped He occurring in specific cavities of the crystalline structure. Extraction of He isotopes from meliphanite by its step-wise heating in vacuum confirmed this conclusion. Using U-Th-4He system for dating (as it is often done in thermochronology) can lead to incorrect results. Both isotopes, 3He and 4He, should be used to identify the origin of helium in minerals.

One of the highly debatable issue of the Altai Pleistocene paleogeography is the chronology and extension of the last ice-dammed lakes. For the first time paleontological, mineralogical characteristics, and optically stimulated luminescence (OSL) ages for lacustrine deposits confirm accumulation of ice-dammed lake with depth at least 170 m in Kurai basin at the end of the Late Pleistocene - 16-19 ka. New data provide information about the ecology and evolution of this Sartan reservoir. Draining of this lake less affected the topography in comparison with earlier cataclysmic glacier-lakes outburst floods. Nevertheless, the lake controlled human settlement of the basin in the Late Paleolithic. Drying of this reservoir defined formation of the modern hydrological network, including flowing of the Chuya River along the steep gorge between the Maashey and Belgibash mouths. New data evidence for significant difference in evolution of the Kurai-Chuya system of intermountain depressions and Uimon basin at the end of the Late Pleistocene.

We register wheat (Triticum aestivum L.) lines MNR434 (Reg. no. GP‐1041, PI 689522) and MNR527 (Reg. no. GP‐1040, PI 689521) as new sources of rust resistance germplasm. These two wheat lines were developed via ethyl methane sulfonate (EMS) mutagenesis of ‘Alpowa’ and identified after stem rust screening using a Puccinia graminis f. sp. tritici isolate virulent to the wild‐type followed by one backcross to Alpowa and six generations of self‐pollination. MNR434 has shown new resistance to stem, stripe, and leaf rusts, and MNR527 has new resistance to stem and stripe rusts, but not leaf rust. The mutations that conferred rust resistance did not significantly reduce grain yield compared with the wild‐type allele in a near isogenic background under greenhouse and field conditions.

Sistem informasi adalah kumpulan eleman yang saling berhubungan satu sama lain yang berbentuk satu kesatuan untuk mengintegrasikan data; memproses dan menyimpan serta mendistribusikan informasi. Sistem informasi dapat di definisikan sebagai suatu sistem yang dapat dibuat oleh manusia yang terdiri dari beberapa komponen dalam organisasi untuk mencapai suatu tujuan yang menyajikan informasi. Sistem informasi ini dapat diakses menggunakan computer ataupun smartphone. Pada sistem informasi ini terdapat beberapa menu yang menyediakan banyak informasi antara lain seperti kegiatan-kegiatan yang akan diselenggarakan oleh Suku Dinas Kehutanan Kota Administrasi Jakarta Utara; pendaftaran TPU; penyimpanan data-data TPU di Kota Jakarta Utara dan pembayaran tagaihan TPU Kota Jakarta Utara.
Pengenalan Wajah Menggunakan Metode Principal Component Analysis (PCA) dan Canberra Distance
Authors: Rosyani Perani
Published: September 2019

Wajah merupakan salah satu karakteristik biometrik yang digunakan untuk mengenali seseorang selain karakteristik yang lain seperti ucapan; sidik jari; retina; dll. Wajah adalah struktur multidimesi yang sangat kompleks dan membutuhkan tehnik komputasi yang baik untuk pengenalan. Di dalam penelitian ini; penulis mengambil 10 pose wajah yang berbeda kemudian menggunakan metode PCA untuk pengoptimalan dalam mereduksi dimensi. Setelah citra original di ekstraksi menggunakan PCA maka akan di hitung tingkat kesamaan (similarity degree)  antara gambar test dengan gambar training menggunakan metode jarak. Hasil dari penelitian ini adalah tingkat kesamaan yang dihasilkan setelah proses reduksi dan ekstraksi menggunakan PCA didapatkan rata-rata nilai untuk Canbera Distance adalah 77;59.

Pengaruh Hasil Belajar Siswa dengan Menggunakan Multi Media Pembelajaran Interaktif untuk Sekolah Menengah Pertama dan Sekolah Menengah Atas
Authors: Wijoyo Agung
Published: September 2019

Multimedia Interaktif adalah suatu media yang terdiri dari bayak komponen atau media yang terhubung satu sama lain dan mampu berinteraksi. Pengajaran media dalam bentuk multimedia interaktif memiliki kemampuan untuk menyimpan audio visual data, membuat multimedia interaktif khususnya interaktif pembelajaran sebagai pendukung metode pembelajaran konvensional yang dulu disampaikan melalui buku dan penjelasan langsung tanpa contoh dianggap kurang mudah dicerna oleh anak-anak, sehingga diharapkan pemanfaatan media interaktif yang bertujuan untuk meningkatkan hasil belajar dapat menjelaskan bahwa media pembelajaran interaktif mampu memberikan informasi dengan lebih menarik dan menyenangkan dari pada harus mendengarkan materi yang diberikan oleh pendidik.Seperti kita ketahui pelajaran Fisika merupakan momok bagian sebagian siswa-siswi SMP-SMA. Mereka sulit menyerap pelajaran Fisika karena guru sudah membebani siswa dengan rumus-rumus yang membuat siswa semakin pusing.Dengan Multimedia Pembelajaran Interaktif Fisika diharapkan para siswa dapat memahami konsepnya terlebih dahulu, sehingga siswa yang awalnya tidak menyukai pelajaran Fisika maka akan menyukai Pelajaran Fisika dan sekaligus dapat meningkatkan prestasi belajar.
