Implementation of Web-Based Virtual Laboratory Media in Learning
Authors: Susilawati Puspita Ratna
Published: January 2020

The integration of information and communication technology in learning through the application of virtual laboratory media can be an alternative solution to overcome the constraints of time, cost, and laboratory safety in biology labs. Virtual laboratories are very suitable to be applied to the mechanism of evolution because they involve the context of space and time, and can provide opportunities for students to learn independently and increase active student involvement in learning. These study aims are to determine the effect of the application of virtual laboratory media on the understanding of student concepts; knowing increasing students' understanding of the concept of evolutionary mechanisms, and knowing students' responses after learning with virtual laboratories.This type of research is a pre-experimental design (nondesign) with one group pretest-posttest design. The research subjects were 37 students. The media used as many as 8 web-based virtual laboratory programs (online) that can be freely accessed. Data collection techniques include tests (pretest and posttest) and questionnaires. The pretest and posttest values were analyzed by the T-test while the questionnaire data were analyzed descriptively. The application of web-based virtual laboratory media on the evolution mechanism material influences the understanding of student concepts (t arithmetic> t table then H0 is rejected and H1 is accepted) The application of these media increases students' understanding of the concept of evolutionary mechanisms. The mean value increased from pretest 23.65 to 56.08 at the posttest with an increase of 32.43. Student responses to the application of media in learning showed 91.89% of students felt helped in understanding the process of evolution while 100% of students felt helped in understanding the role of evolution in causing evolution.

El fantasma de la nación cultural en el edificio del Estado racional
Authors: Ehret Peter
Published: January 2020

A pesar de la legitimación cívica de los Estados constitucionales, la población sigue reproduciendo las identidades de una nación cultural. El enfoque unilateral sobre la legitimidad jurídica de los Estados modernos obvia su anclaje en una identidad cultural particular. De ese modo, no se cumplen las premisas universalistas del Estado racional, ya que nos encontramos con una implícita aceptación de la nación cultural. Frente a ello, la reflexión hegeliano sobre las premisas culturales de Herder indica hacia a una posible salida de este dilema. Hegel sitúa su Estado en un concepto dinámica de sociedad que posibilita anclar el Estado racional en la diversidad cultural de la población.
Francisco Suárez: La emergencia de los tiempos modernos
Authors: Carpintero Benítez Francisco
Published: January 2020

Francisco Suárez se inserta en la línea de los escolásticos españoles del siglo XVI, especialmente de los dos jesuitas que, junto con él, culminan esta escuela: Gabriel Vázquez de Belmonte y Luis de Molina. Se diferencia de ellos en que él es nominalista. Se adelantó a los autores de la Edad Moderna en la carrera por las libertades típicamente modernas, tales como la afirmación de los derechos subjetivos naturales, la democracia como la forma más natural o más próxima a la libertad del hombre, la libertad de conciencia (no de cultos). Estuvo omnipresente en los escolásticos de las Edades Modernas y Contemporánea que, de hecho, entendieron que él culminó la escolástica, de forma tal que también Tomás de Aquino debe ser interpretado a la luz de sus escritos.
El proceso o de cómo Kavka ayunó en el vientre del cuervo
Authors: Fersini Maria Pina
Published: January 2020

Las páginas de Kafka están repletas de figuras animales, cuya compleja simbología, que ha dado lugar a distintas interpretaciones, es capaz de hospedar también una lectura político-jurídica. Partiendo de un diálogo entre las historias con motivo animal de Franz Kafka y los seminarios de Jacques Derrida sobre la bestia y el soberano, el trabajo aspira: por un lado, a aclarar el sentido político-jurídico que, en la narrativa de Kafka, adquieren tanto el devenir animal como el devenir humano; y, por el otro, a indagar el papel del cuervo y de su complejo simbolismo en determinados escritos del escritor checo. De ahí, dirige la mirada al apetito corvino que Kafka escenifica en El proceso para demostrar que la pasión del derecho moderno por la carne pertenece a la naturaleza más primitiva del mismo.
Multidimensional Understanding of Religiosity/Spirituality: Relationship to Major Depression and Familial Risk
Authors: McClintock Clayton , Anderson Micheline , Svob Connie , Wickramaratne Priya , Neugebauer Richard , Miller Lisa , Weissman Myrna M.
Published: January 2020

Background. Previous research has shown prospectively that religiosity/spirituality protects against depression, but these findings are commonly critiqued on two grounds, namely: 1) apparent religiosity/spirituality reflects merely an original absence of depression or elevated mood and 2) religiosity/spirituality too often is measured as a global construct. The current study investigates the relationship between depression and religiosity/spirituality by examining its multidimensional structural integrity. Method. Confirmatory factor analyses with a previously observed cross-cultural factor structure of religiosity/spirituality variables were conducted on an independent sample, diagnostic and familial risk subgroups from this sample, and a subsample of the original cross-cultural sample. Linear regressions onto a previous diagnosis of major depressive disorder (MDD) five years prior to assess potential attenuating impact of a previous depression were explored.Results. Across familial risk groups and clinical subgroups, each of the previously validated religiosity/spirituality domains was confirmed, namely: religious/spiritual commitment, contemplative practice, sense of interconnectedness, experience of love, and altruistic engagement. Previous MDD diagnosis was associated with lower religious/spiritual commitment among high risk individuals, higher contemplation among low risk individuals, and lower importance of religion or spirituality regardless of risk group. Conclusions. Structural integrity was found across familial risk groups and diagnostic history for a multidimensional structure of religiosity/spirituality. Differential associations between a previous diagnosis of MDD and level of religiosity/spirituality across domains suggest a complex and interactive relation between depression, familial risk, and religiosity/spirituality. Accounting for an empirically valid, multidimensional understanding of religiosity/spirituality may advance research on mechanisms underlying the relationship between religiosity/spirituality and mental health.

Sex, drugs, and early emerging risk: Examining the association between sexual debut and substance use across adolescence
Authors: Clark D. Angus , Donnellan M. Brent , Durbin C. Emily , Nuttall Amy K. , Hicks Brian M. , Robins Richard
Published: January 2020

Sexual debut, or first intercourse, predicts problem behaviors such as substance use. This association could reflect a direct effect of debut itself, general developmental trends, or the fact that some youth are more predisposed to a wide array of problem behaviors (e.g., risky sex, substance use). Understanding the association between sexual debut and substance use thus requires methods that can distinguish between these various accounts. In this study the association between sexual debut and substance use was investigated in a longitudinal sample of Mexican-origin youth (N = 674) assessed annually from 5th (Mage = 10.86 years, SD = 0.51) through 12th grade (Mage = 17.69 years, SD = 0.48). The longitudinal aspect of the data allowed the direct effect of sexual debut on substance use to be tested while accounting for long-term trends in substance use, and stable individual differences in those trends based on early risk and debut timing. Substance use increased over time, and early risk and debut were consistently associated with more substance use. Sexual debut also modestly predicted an increase in substance use after accounting for these effects, however. Taken together, results provide some evidence consistent with each of the potential explanations for the association between sexual debut and substance use across adolescence.
The Dynamic Processing Model of Working Memory
Authors: Rose Nathan
Published: January 2020

Recent shifts in the understanding of how the mind and brain retain information in working memory (WM) call for revision to traditional theories. Evidence for the existence of dynamic, “activity-silent” short-term retention processes in the brain diverge from conventional models that have argued that information is always retained in WM by sustained neural activity in buffers. Such evidence comes from the use of machine-learning analytic approaches to decode patterns of brain activity and the simultaneous administration of transcranial magnetic stimulation (TMS) to causally manipulate brain activity in specific areas and time-points. TMS has been used to 'ping' brain areas and reactivate latent representations retained in WM and affect memory performance. These findings argue for a supplement to the sustained retention mechanisms associated with attending to information in WM. Moreover, brain decoding methods reveal that dynamic levels of representational codes are retained in WM, which vary according to task context, from perceptual/sensory codes in posterior areas to more abstract, recoded representations distributed across frontal-parietal regions. A Dynamic Processing Model of WM is advanced to account for the overall pattern of results.Keywords: activity-silent, short-term memory, working memory, sensory-motor recruitment
Overconfidence Bias for Location Unaffected by Metacognitive Aid
Authors: Hutcheson Adam , Vilkov Olga
Published: January 2020

The Dunning-Kruger overconfidence bias is found in many domains of cognitive performance. Prior studies have shown that people can accurately judge their ability to point to familiar locations relative to other cognitive tasks. This research attempted to investigate the existence of the overconfidence bias in a spatial location task. In doing so, we hope to shed light on the underlying theoretical explanation for the overall effect. It was found that giving participants a chance to use their spatial location memory before having to assess their ability did not affect their self-assessments. It was concluded that the dual-curse account of the Dunning-Kruger effect is a better explanatory position than the metacognitive view, as the dual-curse holds that those with lower performance in a domain have a diminished ability to assess their performance in that domain.
Known Knowns and Known Unknowns on Behavior Change Interventions and Mechanisms of Action
Authors: Hagger Martin S , Moyers Susette , McAnally Kaylyn , Mckinley Lauren
Published: January 2020

Systematic reviews and meta-analyses play an important role in summarizing current research on the efficacy of behavior change interventions and their mechanisms of action. The reviews in this special issue represent a ‘step change’ in evaluating current evidence on behavior change interventions and mechanisms. This article outlines the findings and emerging issues identified in the reviews (‘known knowns’), and summarizes evidence gaps to be addressed in future research (‘known unknowns’). Findings indicate that tests of mechanisms of behavior change interventions are not routinely conducted in primary studies and research syntheses; reviews and studies do not sufficiently account for study quality; substantive variability exists in descriptions of intervention content and putative mediators implicated in their mechanisms of action; limited data is available on the efficacy of many behavior change techniques; and moderators of intervention effects and mechanisms are seldom taken into account. Possible solutions include testing effects of isolated behavior change techniques and mechanisms of action; routine evaluation of study quality in behavioral intervention research; development of an evidence base linking behavior change techniques with theory-based constructs that comprise mechanisms of action; adoption of fit-for-purpose methods for synthesizing behavioral intervention mechanisms of action; and routine testing of moderators in intervention research.
Computational and Behavioral Markers of Model-based Decision Making in Childhood
Authors: Smid Claire Rosalie , Kool Wouter , Hauser Tobias U. , Steinbeis Nikolaus
Published: January 2020

Human decision-making is underpinned by distinct systems that differ in flexibility and associated cognitive cost. A widely accepted dichotomy distinguishes between a cheap but rigid model-free system and a flexible but costly model-based system. Typically, humans use a hybrid of both types of decision-making depending on environmental demands. However, children’s use of a model-based system during decision-making has not yet been shown. While prior developmental work has identified simple building blocks of model-based reasoning in young children (1-4 years old), there has been little evidence of this complex cognitive system influencing behavior before adolescence. Here, by using a modified task to make engagement in cognitively costly strategies more rewarding, we show that children aged 5 to 11-years (N = 85), including the youngest children, displayed multiple indicators of model-based decision making, and that the degree of its use increased throughout childhood. Unlike adults (N = 24), however, children did not display adaptive arbitration between model-free and model-based decision making. Our results demonstrate that throughout childhood, children can engage in highly sophisticated and costly decision-making strategies. However, the flexible arbitration between decision-making strategies might be a critically late-developing component in human development.
System justification among the disadvantaged: A triadic social stratification perspective
Authors: Caricati Luca , Owuamalam Chuma Kevin
Published: January 2020

For the past 25 years, the field of social and political psychology has embraced the idea that humans possess a special system justification motivation which causes even members of disadvantaged groups to support societal systems that ostensibly operate against their personal and group interests. Recently, this system justification motive explanation has been challenged, based on mounting empirical evidence to the contrary. However, the potential demise of this dominant perspective invites explanations for the system justification phenomenon, especially amongst the disadvantaged. Existing interest-based accounts, such as the social identity model of system attitudes have tried to fill this gap, but have generally focused on system rationalisation processes within dyadic systems that pitch disadvantaged groups against their privileged counterparts alone. The current contribution extends the existing interest-based accounts by explaining system justification effects in multi-stratified social systems. Based on the triadic social stratification theory, we propose that system justification among the disadvantaged may result from favourable inter-status comparisons within a multi-stratified social system.
Platform Governance as Reflexive Coordination – Mediating Nudity, Hate Speech And Fake News On Facebook
Authors: Katzenbach Christian , Gollatz Kirsten
Published: January 2020

Digital platforms have become dominant players in contemporary societies by positioning themselves as key sites for social communication and transactions. While there is already a growing body of research on specific aspects of platform governance (algorithms, content moderation, policies), there is still only little theoretical grounding of these debates in social theory. This paper addresses this gap by proposing a concept of platform governance based on institutional theory that understands governance as reflexive coordination, and thus different from regulation. Such a concept promises instructive insights into different forms of mediating communication and transactions by platforms. In the second part of the paper, we apply this concept to content moderation and regulation on Facebook. This empirical part is based on a study of the evolving policies and practices with regard to handling controversial content (nudity, hate speech, fake news) on the platform over a timeframe of 10 years. This is contextualised with a discourse analysis of public debates and policy proposals on these issues.
Population Change and Income Inequality in Rural America
Authors: Butler Jaclyn L.W. , Wildermuth Grace , Thiede Brian C. , Brown David L.
Published: January 2020

This paper examines the effects of population growth and decline on county-level income inequality in the United States from 1980 to 2016. Findings from previous research have shown that income inequality is positively associated with population change, but these studies have not explicitly tested for differences between the impacts of population growth and decline. Understanding the implications of population dynamics is particularly important given that many rural areas are characterized by population decline. We analyze county-level data (n=15,375 county-decades) from the Decennial Census and American Community Survey (ACS), applying fixed effects models to estimate the respective effects of population growth and decline on income inequality, to identify the processes that mediate the links between population change and inequality, and to assess whether these effects are moderated by county-level economic and demographic characteristics. We find evidence that population decline is associated with increased levels of income inequality relative to counties experiencing stable and high rates of population growth. This relationship remains robust across a variety of model specifications, including models that account for changes in counties’ employment, sociodemographic, and ethnoracial composition. We also find that the relationship between income inequality and population change varies by metropolitan status, baseline level of inequality, and region.
Reply to: Nix and Lozada (2020), “Do police killings of unarmed persons really have spillover effects? Reanalyzing Bor et al. (2018)”
Authors: Brr Jacob , Venkataramani Atheendar , Williams David , Tsai Alexander C.
Published: January 2020

Nix and Lozada (2020) provide a critique of our 2018 paper, “Police killings and their spillover effects on the mental health of black Americans: a population-based, quasi-experimental study.” They take issue to our use of crowdsourced data from the Mapping Police Violence project database on whether or not a given victim was unarmed, our main exposure measure, and argue that 93 cases were miscoded as unarmed in these data. They then argue that recoding or dropping these 30% cases led to an attenuated and statistically non-significant estimate of the effect of these events on mental health outcomes among black American adults. In this reply, we argue that (1) our use of the Mapping Police Violence project data was carefully considered and scientifically valid both from a theoretical and analytic perspective, and (2) that the difference between our estimates and Nix and Lozada’s do not arise from “miscoding” as the authors claim, but rather a different definition of what constitutes an unarmed victim. To probe the robustness of our results, we estimate 128 regressions models representing all combinations of exclusions of the seven classes of events Nix and Lozada dispute as being unarmed. The estimates are uniformly positive (i.e., all indicative of a harmful relationship between exposure to these events at the state-level and mental health outcomes), and the range of estimates overlap substantially with the 95% confidence interval for our original point estimate.
Scaling Occupations in Intergenerational Research - An Evaluation with Swedish register data
Authors: Hällsten Martin
Published: January 2020

We evaluate how different occupational scales prevalent in the literature can capture intergenerational transmissions in Sweden. Previous research is limited by not taking competing dimensions of SES transmission into account when assessing performances of occupational scales. Using Swedish administrative data, we find, in contrast to classical findings, that the composite International Socio-Economic Index of occupational status (ISEI) has the highest intergenerational correlations net of other SES dimensions (education, income and wealth), followed by Treiman measure of occupational prestige (SIOPS). The now popular measure of occupational education following from Hauser and Warren (1997) suffer from slightly larger overlap with education; more of its intergenerational correlation is explained by parents’ education. However, similar to Hauser and Warren, we find monetary scales of occupations based on earnings or wages to have lower intergenerational significance. The CAMSIS scale for status lies in between occupational earnings and education.

Selling off the Crown Jewels: Socialization of Costs and Privatization of Profits in the Canadian Isotopes Industry
Authors: Khelfaoui Mahdi
Published: January 2020

This article explores the privatization process of a nuclear Crown corporation, the Radiochemical Company (rcc), under Brian Mulroney’s two Progressive Conservative governments. The rcc specialized in processing and commercializing radioactive isotopes for the medical market, an industry in which it was a major global player. Between 1984 and 1991, several stakeholders, including the rcc’s parent company Atomic Energy of Canada Limited, the Ministry of Energy, Mines and Resources, the Ministry of Finance, and the Canada Development and Investment Corporation, tried to define and shape the terms of the privatization. As a result, the process did not follow a straightforward path since it triggered conflicting political and strategic interests. Through the rcc’s case, this article provides a comprehensive account of the institutional mechanisms that were at play during the application of the Conservatives’ divestiture policy. Contrary to what the government’s rhetoric suggested, privatizing the rcc did not put an end to public spending in the medical isotopes business. The opposite actually happened as the rcc’s sale resulted in socializing the costs and privatizing the profits of this lucrative branch of the Canadian nuclear industry.

Published: January 2020

SMEs have been efficiently used as the vehicles for promoting innovation, productivity, and the competitiveness of a country's national economy. Across the globe, SMEs have been playing a distinctive role in achieving the socio-economic objectives such as employment generation, poverty reduction, equalizing the distribution of national wealth, fostering innovation, and nurturing institutional competitiveness. The main objective of this study is to empirically examine the extent to which financial constraints hamper the growth of SMEs in Sindh, Pakistan. To collect the primary data, survey questionnaires were distributed to 100 SMEs from different economic sectors and registered in the Chamber of Commerce Offices in Sindh. Seven (7) critical financial constraints to SMEs were determined through the literature and included in the questionnaire. The data were analyzed through descriptive analysis and correlation techniques. The results show that SMEs in Pakistan are severely constrained by financing, particularly external equity. Financial ecosystem for SMEs in Pakistan is not friendly and one-size fits all rules and regulations may not suffice the financing needs of SMEs in Pakistan. It has been observed that the institutional weaknesses and market failures exacerbate the financial constraints of SMEs. The government, exclusively, should develop specialized banks and funds to cater to the financing needs of SMEs in their various stages of the business cycle. Furthermore, the Credit Guarantee Schemes (CGS) should also be launched to share the risk of Financial Institutions for lending to the SMEs

PENGARUH PENERAPAN GOVERNANCE, RISK, AND COMPLIANCE (GRC) TERHADAP KINERJA PERUSAHAAN
Authors: Dian Anatasy dan Novita
Published: January 2020

Penelitian ini bertujuan untuk mengetaui pengaruh penerapan Governance, Risk, and Compliance terhadap kinerja perusahaan baik kinerja keuangan maupun non keuangan. Untuk perusahaan yang bergerak dalam penyediaan jasa keuangan, hasil penelitian ini diharapkan dapat memberikan kontribusi terkait penerapan GRC agar dapat meningkatkan kualitas kinerja BPR dan mencapai tujuan yang diharapkan. Responden yang digunakan dalam penelitian ini adalah karyawan dari BPR. Data dikumpulkan dengan menggunakan wawancara, observasi dan kuesioner. Metode analisis deskriptif dan analisis verifikatif digunakan untuk menguji hipotesis dan structural modeling dengan aplikasi Partial Least Square yaitu Program SmartPLS versi 3. Hasil penelitian menunjukkan bahwa dari ketiga konsep yang digunakan yaitu Governance (GCG), Risk, and Compliance hanya Risk yang memiliki pengaruh secara signifikan terhadap kinerja perusahaan baik kinerja keuangan dan non keuangan. Hal tersebut dikarenakan ada beberapa faktor seperti lingkup BPR yang lebih kecil jika dibangdingkan Bank Konvensional, BPR memiliki jumlah karyawan yang kecil maka dari itu implementasi dari penerapan GRC belum secara optimal diterapkan
The effectiveness of tranexamic acid on operative and perioperative blood loss in long-segment spinal fusions: a consecutive series of 119 primary procedures

Published: January 2020

OBJECTIVE

The aim of this study was to determine if the use of tranexamic acid (TXA) in long-segment spinal fusion surgery can help reduce perioperative blood loss, transfusion requirements, and morbidity.

METHODS

In this retrospective single-center study, the authors included 119 consecutive patients who underwent thoracolumbar fusion spanning at least 4 spinal levels from October 2016 to February 2019. Blood loss, transfusion requirements, perioperative morbidity, and adverse thrombotic events were compared between a cohort receiving intravenous TXA and a control group that did not.

RESULTS

There was no significant difference in any measure of intraoperative blood loss (1514.3 vs 1209.1 mL, p = 0.29) or transfusion requirement volume between the TXA and control groups despite a higher number of pelvic fusion procedures in the TXA group (85.9% vs 62.5%, p = 0.003). Postoperative transfusion volume was significantly lower in TXA patients (954 vs 572 mL, p = 0.01). There was no difference in the incidence of thrombotic complications between the groups.

CONCLUSIONS

TXA appears to provide a protective effect against blood loss in long-segment spine fusion surgery specifically when pelvic dissection and fixation is performed. TXA also seems to decrease postoperative transfusion requirements without increasing the risk of adverse thrombotic events.

Published: January 2020

OBJECTIVE

Posterior fixation with interbody cage placement can be accomplished via numerous techniques. In an attempt to expedite recovery by limiting muscle dissection, midline lumbar interbody fusion (MIDLIF) has been described. More recently, the authors have developed a robot-assisted MIDLIF (RA-MIDLIF) technique. The purpose of this study was to compare the index episode-of-care (iEOC) parameters between patients undergoing traditional open transforaminal lumbar interbody fusion (tTLIF), MIDLIF, and RA-MIDLIF.

METHODS

A retrospective review of a prospective, multisurgeon surgical database was performed. Consecutive patients undergoing 1- or 2-level tTLIF, MIDLIF, or RA-MIDLIF for degenerative lumbar conditions were identified. Patients in each cohort were propensity matched based on age, sex, smoking status, BMI, diagnosis, American Society of Anesthesiologists (ASA) class, and number of levels fused. Index EOC parameters such as length of stay (LOS), estimated blood loss (EBL), operating room (OR) time, and actual, direct hospital costs for the index surgical visit were analyzed.

RESULTS

Of 281 and 249 patients undergoing tTLIF and MIDLIF, respectively, 52 cases in each cohort were successfully propensity matched to the authors’ first 55 RA-MIDLIF cases. Consistent with propensity matching, there was no significant difference in age, sex, BMI, diagnosis, ASA class, or levels fused. Spondylolisthesis was the most common indication for surgery in all cohorts. The mean total iEOC was similar across all cohorts. Patients undergoing RA-MIDLIF had a shorter average LOS (1.53 days) than those undergoing either MIDLIF (2.71 days) or tTLIF (3.58 days). Both MIDLIF and RA-MIDLIF were associated with lower EBL and less OR time compared with tTLIF.

CONCLUSIONS

Despite concerns for additional cost and time while introducing navigation or robotic technology, a propensity-matched comparison of the authors’ first 52 RA-MIDLIF surgeries with tTLIF and MIDLIF showed promising results for reducing OR time, EBL, and LOS without increasing cost.
