Published: May 2021

Trim loss merupakan kerugian yang timbul dari hasil pemotongan yang tidak optimal. Trim loss dipengaruhi beberapa faktor salah satunya yaitu peletakan pola pemotongan yang kurang tepat. Trim loss dapat diselesaikan dengan beberapa metode salah satunya menggunakan metode cutting stock. cutting stock digunakan pada pengoptimalan pemotongan sisa material yang tidak dapat digunakan lagi. Pada cutting stock dipengaruhi oleh masalah pola pemotongan disebut cutting stock problem(CSP). CSP dapat diselesaikan dengan menggunakan pendekatan integer linear programming (ILP). ILP adalah salah satu model dalam program linear yang variabel keputusannya berbentuk bilangan positif atau nol.

Developing a Comprehensive Framework for Crowd Funding Factors by Using the Hexagon Technique
Authors: Haji Gholam Saryazdi Ali , Rajabzadeh Ghatari Ali , Mashayekhi Alinaghi , Hasanzadeh Alireza
Published: May 2021

In recent years, crowd funding has seriously been considered as a novel method of financing start-up businesses and innovative ideas. In its short life time so far, the method has significantly grown in different aspects such as the number of proposed platforms, the number of campaigns and their success rate, the amount of capital provided, and the number of proposed models. In addition, various researchers have investigated the phenomenon from different points of view. Nevertheless, just a few studies have carried out a comprehensive review of the factors affecting this method. The main purpose of this research is to design and implement a comprehensive framework for factors that affect crowd funding. In order to achieve this goal, the effective factors in this regard were first identified through systematic review of the literature on crowd funding. Then, they were classified and clustered in a hexagonal framework based on the stakeholder's model. In other words, a qualitative method is used to extract the factors affecting crowd funding. The hexagons extracted from the literature were in 82 clusters out of which 38 were accounted for by capital seekers, 16 by investors and platforms, and 12 by other stakeholders. This study is the first effort to design a comprehensive framework for factors that affect crowd funding. Doi: 10.28991/HIJ-2021-02-02-07 Full Text: PDF
Relativistic Extended Thermodynamics of Polyatomic Gases with Rotational and Vibrational Modes
Authors: Pennisi Sebastiano
Published: May 2021

In a recent article an infinite set of balance equations has been proposed to modelize polyatomic gases with rotational and vibrational modes in the non-relativistic context. To obtain particular cases, it has been truncated to obtain a model with 7 or 15 moments. Here the following objectives are pursued: 1) to obtain the relativistic counterpart of this model which, at the non-relativistic limit, gives the same balance equations as in the known classical case; 2) to obtain the previous result for the model with an arbitrary but fixed number of moments, 3) to obtain the closure of the resulting relativistic model so that all the functions appearing in the balance equations are expressed in terms of the independent variables. To achieve these goals, the following methods are used: 1) The Entropy Principle is imposed. As a result is obtained that the closure is determined up to a single 4-vectorial function usually called 4-potential. 2) To determine this last function, a more restrictive principle is imposed, namely the Maximum Entropy Principle (MEP). 3) Since all the functions involved must be expressed in the covariant form, so as not to depend on the observer, the Representation Theorems are used. Findings of this article are exactly the goals outlined earlier. They are clearly novelty because they had never been achieved before. They can be considered also improvements because, if the aforementioned arbitrary number of moments is restricted to 16, the present work coincide with that already known in literature. Doi: 10.28991/HIJ-2021-02-03-04 Full Text: PDF

On k-Fair Total Domination in Graphs
Authors: Bent-Usman Wardah Masanggila , Isla Rowena T.
Published: May 2021

Let G = (V (G), E(G)) be a simple non-empty graph. For an integer k â‰¥ 1, a k-fairtotal dominating set (kf td-set) is a total dominating set S âŠ† V (G) such that |NG(u) âˆ© S| = k for every u âˆˆ V (G)\S. The k-fair total domination number of G, denoted by Î³kf td(G), is the minimum cardinality of a kf td-set. A k-fair total dominating set of cardinality Î³kf td(G) is called a minimum k-fair total dominating set or a Î³kf td-set. We investigate the notion of k-fair total domination in this paper. We also characterize the k-fair total dominating sets in the join, corona, lexicographic product and Cartesian product of graphs and determine the exact values or sharpbounds of their corresponding k-fair total domination number.

El Derecho a la Educación Intercultural Bilingüe en el Ecuador
Authors: Rodriguez Caguana Adriana
Published: May 2021

La vigencia de los derechos de los pueblos indígenas se encuentra ligada a su propia historia política, la misma que se articuló entre derrotas y paulatinas reivindicaciones, para finalmente llegar al reconocimiento de un Estado Plurinacional (2008). En la actualidad la Educación Intercultural Bilingüe (EIB) ya no es una institución autónoma del Movimiento Indígena (MI) -la autonomía se perdió desde la aprobación de la nueva ley de Educación Intercultural, el 11 de enero de 2011- lo que nos invita a reflexionar sobre el rol del Movimiento Indígena en la consecución del derecho a la educación indígena. El MI mantuvo su lengua como símbolo de resistencia contra el conquistador; sin embargo, el camino recorrido detalla algo más que la permanencia, o resistencia de un símbolo; la necesidad de autodefinirse como pueblo. En el presente trabajo se trata de articular la relación histórica del MI con el Estado ecuatoriano en cuanto a la reivindicación paulatina del derecho a la educación indígena hasta llegar a la nueva ley de Educación Intercultural del 2011.

The composition of the surface of natural diamonds in interaction with kimberlite minerals and the aqueous phase in the depositand enriched ore is studied. The sequence and conditions for the formation of minerals on the surface of crystals under conditionsof processing of kimberlites have been determined. Confirmed the mechanism of hydrophilization of diamonds comprising crystallizationof hydroxides and oxides of iron as a mandatory initial stage. A method of destruction or subsequent dissolution of mineralsaggregates by the impact of electrolysis products of aqueous systems has been proposed, which allows to restore the hydrophobicityof diamonds. The use of electrochemically treated water in the froth separation cycle with high diamond recovery made it possibleto increase their recovery in the factory’s concentrate by 8.8%.

Published: May 2021

Prevalence of non-communicable diseases (NCDs) is growing globally, with the greatest increase in NCD deaths expected to occur in sub-Saharan Africa (SSA) over the next five to 15 years. Tobacco use is implicated in all leading NCDs, and is one of the biggest global public health threats. Despite the projected increase in tobacco-related NCD deaths in low- and Middle-income countries (LMICs), research on tobacco control policy and implementation in SSA and more specifically, Ghana, is a low priority. To address these challenges, the School of Public Health (KNUST, Ghana) with support from the Tobacco Control Capacity Program (TCCP) funded by the Global Challenges Research Fund (GCRF) organized a 1-day stakeholder’s meeting to discuss the advancement of tobacco control research in Ghana. The aim was to propose the way forward for strengthening applied research that can inform the development of health policies and programs focused on tobacco control. Participants were drawn from academia, research and health institutions, civil society and non-governmental organisations. In this meeting overview, we present the key themes that emerged from the meeting and some strategies for advancing tobacco control research in Ghana and beyond. Directions for future research agenda include building institutional research capacity, strengthening stakeholder and public engagement on tobacco control, need for more local and comprehensive data and research, improve sustainable funding of comprehensive programs on tobacco control in Ghana and social and behavior change communication on tobacco use.

Published: May 2021

Aim: Varicocele, abnormal dilatation of pampiniform venous plexus, is classified into three groups: 1st, 2nd and 3rd grade. The aim of our research is to show the differences among the three different varicocele grades based on the results of their sperm DNA damage and blood biochemical parameters.Methods: We examined 30 patients which were classified into three groups: Group 1 (healthy), Group 2 (grades 1 and 2) and Group 3 (grade 3). The semen samples were examined in terms of DNA damage via comet assay. The blood samples were assessed using catalase (CAT), superoxide dismutase (SOD) enzyme activities and malondialdehyde (MDA) levels.Results: According to the comet findings, Group 2 and Group 3 parameters were significantly higher than Group 1 (p < 0.01). In the biochemical findings, we observed decreased CAT and SOD activities and an increased MDA level for Group 2 and Group 3. In our research, we showed that grades 1 and 2 had significant DNA damage in terms of infertility as much as grade 3.Conclusion: The results we derived indicate that the detection of DNA damage could be used as a predictor of infertility alongside routine semen and morphological analysis.

O multilinguismo caracteriza a existência, no interior de um mesmo território, de diferentes comunidades linguísticas. O objetivo deste artigo é mostrar através de um percurso histórico sobre o Estado de Mato Grosso, o multilinguismo que se instaurou nesse Estado nos últimos 50 anos e as consequências que isso vem causando no sistema linguístico da região, o mosaico linguístico que vem se tornando o falar mato-grossense. Para o desenvolvimento deste estudo, focou-se nas políticas de povoamento do Estado, processos migratórios e expansão territorial pelos quais Mato Grosso passou ao longo de sua história, principalmente na onda migratória provocada pela divisão do Estado em 1979. Apresenta-se aqui a área de estudo, e, para análise, focaliza-se na política de povoamento, nas ondas migratórias, como se deram e os efeitos por elas causados no sistema linguístico do Estado e, com base em elementos que dão sustentação teórica à área da pesquisa sociolinguística, busca-se entender a atual situação do falar mato-grossense. Os resultados do estudo apontam para a expansão territorial do Estado de Mato Grosso, seguida dos processos migratórios e da expansão populacional como fatores que muito contribuíram para a formação no interior do Estado de comunidades linguísticas, que levaram ao multilinguismo na região, contribuindo para que o Estado de Mato Grosso se tornasse um Estado com diversos falares.
Varianti anatomiche
Authors: Mariani Giulia Adalgisa
Published: May 2021

Con il termine variante anatomica si definisce una particolare struttura anatomica la cui morfologia si discosta da quella osservata nella maggior parte degli individui. Diversamente dalle anomalie congenite, che per definizione sono considerate patologiche, le varianti rientrano in un quadro di normalità. È però evidente che conformazioni anatomiche peculiari possono interferire con le procedure diagnostiche e aumentare il rischio di complicanze durante gli interventi chirurgici. La conoscenza dell’anatomia umana e lo studio delle sue varianti rappresentano perciò un requisito indispensabile per ogni pratica medica, e l’attività settoria, che consente di individuare e documentare eventuali varianti rispetto alla normale anatomia umana, costituisce un supporto fondamentale alla medicina e alla chirurgia. Il volume propone un excursus storico sulla pratica settoria, una introduzione alle attuali tecniche di dissezione e lo studio di alcune significative varianti anatomiche.

Kısmi bir tartışma dâhilinde de olsa; sanatın ilkel mi yoksa bilinçli ve çağdaş bir edim mi olduğu yönündeki ayrışma devam ediyor. Bir yönüyle de bu, sanatçının yüklendiği / yüklenmesi gereken rolün ve esas olarak sanatın mahiyeti konusunda yeni fikirlerin birbiriyle çatışmasına yol açıyor. Bugün dahi kesin bir yargıya varılamamış olması, ilkel ve tarih öncesi estetik yaratı yetisini tanımlamayı zorlaştırsa da daha yakıcı bir mesele olarak, modern sanatçının ilkel benliğiyle hareket ettiği ve kendisini tarih öncesi insan ile özdeşleştirme çabasında olduğu da dikkatlerden kaçmıyor. Post-modern çağın materyalist hükmü, efsane ve büyü odaklı bu tutumun üzerini örtmüştür kuşkusuz ama yeni, köklü bir dönüşüm ile burun buruna gelindiği şu günlerde, tarih öncesinin uhrevi edimiyle arasındaki benzerlikleri ararken ilkellik kavramı ve modern müze politikalarına da değinerek sanatın esası sorunsalına göndermelerde bulunmak yararlı olacaktır.

Organisms are increasingly facing multiple, potentially interacting stressors in natural populations. The ability of populations coping with combined stressors depends on their tolerance to individual stressors and how stressors interact, which may not be correctly captured in controlled laboratory settings. One largely unexplored reason for this is that the microbial communities in laboratory settings often differ from the natural environment, which could result in different stressor responses and interaction patterns. In this study, we investigated the impact of single and combined exposure to a toxic cyanobacterium and an oomycete-like parasite on the performance of three Daphnia magna genotypes. Daphnia individuals were first sterilized and then experimentally given a natural or a laboratory-derived microbial inoculum. Survival, reproduction and body size were monitored for three weeks and gut microbiomes were sampled and characterized at the end of the experiment. Our study confirmed that natural and laboratory microbial inocula and gut microbiomes are differently structured with natural microbiomes being more diverse than laboratory microbiomes. Our results showed that exposure to the stressors reduced D. magna performance compared to the control. An antagonistic interaction between the two biotic stressors was revealed with respect to D. magna survival, when Daphnia individuals were exposed to the laboratory microbial inoculum. This effect was consistent across all three genotypes. In Daphnia exposed to a natural microbial inoculum this antagonistic interaction could not be detected and the genotype x exposure interaction was genotype dependent. Our results indicate that host-stressor interactions depend on the microbial inoculum and that the gut microbiome has potentially a strong role in this, thereby providing an unexplored dimension to multiple-stressor research.

Fundamental Flaws in Academic, Employment and Professional Tests: Test Score Misuses Are Responsible for Ruined Student Health, Social Injustice and Diminished Competitiveness
Authors: Wu Jianqing
Published: May 2021

In this research, I investigate inherent limitations in school tests and employment tests. I found there is no statistical distribution and no defined observation for test scores. One problem is that personal knowledge must have different substances, degrees and scopes notwithstanding contrary unproved hypotheses. No real test data support the claim that human knowledge follows a well known distribution. A related but more fatal problem is that points of individual questions are assigned arbitrarily, and different points for individual test questions represent things that differ in nature, scope and significance. There is no valid basis for adding points up to arrive at an objective test score. Those findings are strongly backed up by very poor test scores in published studies. Without understanding both flaws in near a century, test scores have been improperly used as ranking parameters and passing criteria. While grades ware kept as secret in early time, the letter grading system became the standard in the U.S. in the 1940’s. Without exploring deep flaws in GPAs, GPAs are improperly used as artificial impediments to student careers. A natural response to the abuse of GPAs is cheating in test to neutralize their unfair effects. Misuse of test scores and GPAs are responsible for the vicious competition, and cheating by some students must force others to do the same. A century of abuse of test scores and GPAs have fostered a cheating culture in the U.S., which fuels a huge international cheating service industry. Now cheating was found among nearly 70% U.S. college students, nearly 90% of high school students, and a good portion of job applicants. This cheating culture and score-based employment practices are about to ruin everything from social justice, fair employment opportunities, U.S. legal process legitimacy, student health, and U.S. competitiveness. Measures for rooting out this cancer must be to reform the test system, change employment practices and eliminate the motivation of cheating.

Dispositional optimism as a buffer against emotional reactivity to daily stressors: A daily diary approach
Authors: Majeed Nadyanna M. , Tan Jacinth Jia Xin , Tov William , Hartanto Andree
Published: May 2021

The current research examined if dispositional optimism buffers against the negative influences of daily stressors on affective experiences, using a daily diary study of two large and nationally-drawn samples of American adults (N=2,349). Optimism, exposure to daily stressors, and daily positive and negative affect were assessed over eight days. Multilevel modelling revealed that optimism significantly attenuated the associations between daily stressor exposure and negative affect reactivity even after controlling for demographic factors, subjective physical health, and socioeconomic status. However, in a similar analysis, the inclusion of socioeconomic variables fully accounted for the moderating effect of optimism on stress and positive affect reactivity. The findings suggest distinct processes that are involved in how optimism reduces daily stress reactivity.

Researchers and practitioners have long been concerned about detrimental effects of socially desirable responding on the structure and criterion validity of personality assessments. The current research examined the effect of reducing evaluative item content of a Big Five personality assessment on test structure and criterion validity. We developed a new public domain measure of the Big Five called the Less Evaluative Five Factor Inventory (LEFFI), adapted from the standard 50-item IPIP NEO, and intended to be less evaluative. Participants (n = 3164) then completed standard (IPIP) and neutralized (LEFFI) measures of personality. Criteria were also collected, including academic grades, age, sex, smoking, alcohol consumption, exercise, protesting, religious worship, music preferences, dental hygiene, blood donation, other-rated communication styles, other-rated HEXACO personality, and cognitive ability (ICAR). Evaluativeness of items was reduced in the neutralized measure. Cronbach's alpha and test-retest reliability were maintained. Correlations between the Big Five were reduced in the neutralized measure and criterion validity was similar or slightly reduced in the neutralized measure. The large sample size and use of objective criteria extend past research. The study also contributes to debates about whether the general factor of personality and agreement with socially desirable content reflect substance or bias.

BackgroundThe risk of depressive relapse and recurrence is associated with social risk factors that may be amplified by a submissive socio-cognitive profile.MethodsIn Study 1 we aimed to identify perceptions of low social status in a community sample (N=613) with a self-reported history of mental health difficulties (n=232) and, more specifically in Study 2 (N=122), in individuals in clinical remission from depression (n=18), relative to a never-depressed control group (n=64), and relative to a group experiencing a current depressive episode (n=40).ResultsIn Study 1, a total of 225 of the 232 participants in the self-reported mental health difficulties group opted to provide further information regarding their mental health history, of whom 153 (68%) reported a history of anxiety, 168 (74.7%) reported a history of depression, and 13 (5.8%) reported an unspecified mental health history. Elevated depressive symptoms were associated with perceptions of low social status which significantly differed between individuals with and without a self-reported history of mental health difficulties. In Study 2 we found enduring perceptions of low social status in remitted depressed individuals.LimitationsWe were unable to discern between historical or current clinical diagnosis in the community sample of Study 1, as we were reliant on self-report. We were unable to explore the effects of medication or causal relationships between depressive symptoms and social status as the studies were cross-sectional in nature.ConclusionsThese findings suggest that evolutionarily rooted socio-cognitive profiles could impact affiliative processes and may confer increased vulnerability to future depressive episodes.
Creating ad hoc graphical representations of number
Authors: Holt Sebastian , Fan Judith , Barner David

The ability to communicate about exact number is critical to many modern human practices spanning science, industry, and politics. Although some early numeral systems used 1-to-1 correspondence (e.g., ‘IIII’ to represent 4), most systems provide compact representations via more arbitrary conventions (e.g., ‘7’ and ‘VII’). When people are unable to rely on conventional numerals, however, what strategies do they initially use to communicate number? Across three experiments, participants used pictures to communicate about visual arrays of objects containing 1-16 items, either by producing freehand drawings or combining sets of visual tokens. We analyzed how the pictures they produced varied as a function of communicative need (Experiment 1), spatial regularities in the arrays (Experiment 2), and visual properties of tokens (Experiment 3). In Experiment 1, we found that participants often expressed number in the form of 1-to-1 representations, but sometimes also exploited the configuration of sets. In Experiment 2, this strategy of using configural cues was exaggerated when sets were especially large, and when the cues were predictably correlated with number. Finally, in Experiment 3, participants readily adopted salient numerical features of objects (e.g., four-leaf clover) and generally combined them in a cumulative-additive manner. Taken together, these findings corroborate historical evidence that humans exploit correlates of number in the external environment – such as shape, configural cues, or 1-to-1 correspondence – as the basis for innovating more abstract number representations.
A Complete Method for Assessing the Effectiveness of Eyewitness Identification Procedures: Expected Information Gain
Authors: Starns Jeffrey Joseph , Cohen Andrew L. , Rotello Caren M.
Published: May 2021

We present a method for measuring the efficacy of eyewitness identification procedures by applying fundamental principles of information theory. The resulting measure evaluates the Expected Information Gain (EIG) for an identification attempt, a single value that summarizes an identification procedure’s overall potential for reducing uncertainty about guilt or innocence across all possible witness responses. In a series of demonstrations, we show that EIG often disagrees with existing measures (e.g., diagnosticity ratios or area under the ROC) about the relative effectiveness of different identification procedures. Each demonstration is designed to highlight key distinctions between existing measures and EIG. An overarching theme is that EIG provides a complete measure of evidentiary value, in the sense that it factors in all aspects of identification performance. Collectively, these demonstrations show that EIG has substantial potential to inspire new discoveries in eyewitness research and provide a new perspective on policy recommendations for the use of identifications in real investigations.
