Evaluation on Maturity Assessment System of Government Internal Control System (SPIP) in Local Government
Authors: Mukhlis Mukhlis , Sumirah Sumirah , Prahesta Adhitya Latif
Published: September 2021

The purpose of this research is to identify problems existing in the maturity assessment system of Government Internal Control System (SPIP) based on the Regulation of the Head of Finance and Development Supervisory Agency (BPKP) Number 4 of 2016 and provide the solutions. The research method was qualitative, using primary data through interview and focus group discussion. Secondary data were in the form of laws and regulations, guidelines, as well as maturity assessment instrument for SPIP. The data analysis used an interactive model. This research found that the current assessment system did not direct the assessment team and quality assurance team to perform an analysis of relationship among SPIP indicators and between SPIP indicators and other governance indicators. In addition, the scoring system is considered to be emphasized more on the fulfillment of administrative evidence rather than the substance of the assessment. Therefore, the assessment system should consider the relationship of variables in the assessment process and put forward the substance of the assessment rather than the completeness of documentation.

Differential expression of glutamic-oxaloacetic transaminase 1-like 1 in human epithelial ovarian cancer.
Authors: Mamoor Shahan
Published: September 2021

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding glutamic-oxaloacetic transaminase 1-like 1, GOT1L1, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. GOT1L1 expression was significantly higher in high-grade serous ovarian tumors relative to normal fallopian tube. GOT1L1 expression correlated with progression-free survival in patients with p53 mutant ovarian cancer. These data indicate that expression of GOT1L1 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. GOT1L1 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.

Epithelial ovarian cancer (EOC) is the most lethal gynecologic cancer (1). We performed discovery of genes associated with epithelial ovarian cancer and of the high-grade serous ovarian cancer (HGSC) subtype, using published and public microarray data (2, 3) to compare global gene expression profiles of normal ovary or fallopian tube with that of primary tumors from women diagnosed with epithelial ovarian cancer or HGSC. We identified the gene encoding pre-B-cell leukemia homeobox 1, PBX1, as among the genes whose expression was most different in epithelial ovarian cancer as compared to the normal fallopian tube. PBX1 expression was significantly lower in high-grade serous ovarian tumors relative to normal fallopian tube. PBX1 expression correlated with progression-free survival in patients with p53 mutant ovarian cancer. These data indicate that expression of PBX1 is perturbed in epithelial ovarian cancers broadly and in ovarian cancers of the HGSC subtype. PBX1 may be relevant to pathways underlying ovarian cancer initiation (transformation) or progression.
Predictive neuronal adaptation as a basis for consciousness.
Authors: Luczak Artur
Published: September 2021

Being able to correctly predict the future and to adjust own actions accordingly, offers great survival advantage. In fact, this could be the main reason for organisms to evolve their brains. The most mysterious feature of brain activity: consciousness, also seems to be related to predicting the future and detecting surprise: a mismatch between actual and predicted situation. Even at the single neuron level, predicting future activity and adapting synaptic inputs accordingly, is the best strategy to maximize metabolic energy for a neuron. Following on those ideas, here we examine if surprise minimization by single neurons could be a basis for consciousness. First, we show in simulations that as a neural network learns a task, then the surprise within neurons, defined as: difference between actual and expected activity, changes similarly as consciousness of a learned skill in humans. Moreover, implementing adaptation of neuronal activity to minimize surprise at fast time scales (tens of ms), resulted in improved network performance. This improvement is likely due to the fact that adapting activity based on the internal predictive model, allows each neuron for a more “educated” response to stimuli. Based on those results, we propose that: neuronal predictive adaptation to minimize surprise could be a basic building block of conscious processing. This is because, adapting activity toward a predicted level, allows neurons to exchange not only information about stimulus but also about its internal model predictions and thus, to build more complex predictive models. To be precise, we provide an equation to quantify consciousness as the amount of surprise minus the size of the adaptation error. Since neuronal adaptation can be studied experimentally, this allows for directly testing our hypothesis. Specifically, we postulate that any substance affecting neuronal adaptation will also affect consciousness. Interestingly, our predictive adaptation hypothesis is consistent with multiple ideas presented previously in diverse theories of consciousness, such as global workspace theory, integrated information, attention schema theory, and predictive processing framework. In summary, we present a theoretical, computational and experimental support for the hypothesis that neuronal adaptation is a possible biological mechanism of conscious processing, and we discuss how this could provide a step toward a unified theory of consciousness.
Seeing Matters: The Remarkable Relevance of the Object-Representation Relationship to Science … and to Society!
Authors: Rosseinsky Nicholas Martin
Published: September 2021

The basic relationship between consciously-experienced representations, and material objects they represent, is hotly debated in some circles. But is it practically important? To investigate this, I introduce new symbolic notation, capable of labelling object, brain-perception, and conscious representation. Simple physics-based reasoning argues against identity of object and representation (rejecting e.g., direct realism). Nevertheless, a pivotal concern of the direct-realism school remains: how do we have knowledge of the world, if it’s only experienced indirectly? I sketch an indirect-school response, and review recent theoretical results showing how it simply doesn’t work in the dynamically-conventional setting (which is the hallmark of modern mainstream science). After illustrating how dynamically-conventional dysfunctions affect the foundations of science itself, I point to an experimentally-based resolution of knowledge-problems (and of the direct/indirect debate itself). Because the foundational problems for science affect its standing in society (for example, in its conflict with postmodernist ‘post-Truth’), the object-representation debate does turn out to have a practical significance, far beyond its conventional, academic/abstract/technical, framing.

Published: September 2021

In the Covid-19 pandemic, digital social connections have taken on a new level of significance. Building on our previous work, we propose a decentralised service model for a digital resilience network (DRN) which enables people with mental and physical illness as well as those experiencing adverse social events to align themselves, provide peer support, share and access resources. The model has five domains: Biopsychosocial, geographical, technological, information and rule domains. Each application of the model can be described using the five domain descriptors and can thereby function as an index which can allow the individual to navigate the networks according to their individual circumstances.
Drifting pitch awareness after exposure to altered auditory feedback
Authors: Franken Matthias K. , Hartsuiker Robert , Johansson Petter , Hall Lars , Lind Andreas
Published: September 2021

Various studies have claimed that the sense of agency is based on a comparison between an internal estimate of an action’s outcome and sensory feedback. With respect to speech, this presumes that speakers have a stable pre-articulatory representation of their own speech. However, recent research suggests that the sense of agency is flexible and thus in some contexts we may feel like we produced speech that was not actually produced by us. The current study tested whether the estimated pitch of one’s articulation (termed ‘pitch awareness’) is affected by manipulated auditory feedback. In four experiments, fifty-six participants produced isolated vowels while being exposed to pitch-shifted auditory feedback. After every vocalization, participants indicated whether they thought the feedback was higher or lower than their actual production. After exposure to a block of high-pitched auditory feedback (+500 cents pitch shift), participants were more likely to label subsequent auditory feedback as “lower than my actual production”, suggesting that prolonged exposure to high-pitched auditory feedback led to a drift in participants’ pitch awareness. The opposite pattern was found after exposure to a constant -500 cents pitch shift. This suggests that pitch awareness is not solely based on a pre-articulatory representation of intended speech or on a sensory prediction, but also on sensory feedback. We propose that this drift in pitch awareness could be indicative of a sense of agency over the pitch-shifted auditory feedback in the exposure block. If so, this suggests that the sense of agency over vocal output is flexible.

Published: September 2021

We discuss an important issue that is not directly related to the main theses of the van Doorn et al. (2021) paper, but which frequently comes up when using Bayesian linear mixed models: how to determine sample size in advance of running a study when planning a Bayes factor analysis. We adapt a simulation-based method proposed by Wang and Gelfand (2002) for a Bayes-factor based design analysis, and demonstrate how relatively complex hierarchical models can be used to determine approximate sample sizes for planning experiments.
Helping in the context of refugee immigration

Published: September 2021

We review psychological approaches of helping behavior in the context of refugee immigration. Refugee migration, compared to non-refugee migration, is characterized by greater forcedness and related perils. Taking into account perceptions of forcedness and perils, we examine potential helpers’ responses at each of four successive stages towards helping people in perilous, distressing, or emergency situations: (1) noticing and recognizing distressing, help-demanding conditions, (2) taking responsibility, (3) knowing how to help, and (4) transfer of one’s knowledge into action. In so doing, we discuss the role of different motives and functions of providing help (e.g., preserving refugees’ dependency or facilitating their autonomy), and implications of unequal power relations between help providers and refugees.
Does Eco Certification Sell Tourism Services? Evidence from a Quasi-Experimental Observation Study in Iceland
Authors: Karlsson Logi , Dolnicar Sara
Published: September 2021

This study investigates – using a quasi-experimental field design – whether eco certification of tourism services affects tourists’ choices of service providers. Results indicate that, in times of high tourism demand, eco certification is unlikely to offer a competitive advantage. In times of low tourism demand, however, the niche segment of tourists who consider environmental impact when booking a tourism service may be of critical value to tourism businesses, making eco certification an attractive long-term risk minimization strategy. The study also shows that tourists’ self-reports of factors affecting their choice of a tour are heavily affected by social desirability bias. As such, they should not be used as a basis for managerial decision making with respect to whether or not eco certification pays should be pursued.
The Nation of Vaccine Development Influences Vaccine Acceptance
Authors: Barceló Joan , Sheen Greg Chih-Hsin , Tung Hans , Wu Wen-Chin
Published: September 2021

What types of vaccines are citizens most likely to accept? We administered a conjoint experiment requesting 15,000 adult citizens across 14 countries from around the world to assess 450,000 profiles of vaccines that randomly varied on seven attributes. Beyond vaccine fundamentals such as efficacy rate, number of doses, and duration of the protection, we find that citizens systematically favor vaccines developed and produced in their own country of residence. These results indicate that a sociological form of vaccine nationalism shapes vaccine acceptance. The extent of preference in favor of vaccines developed and produced within the national borders is particularly large among citizens who identify more strongly with their nation, suggesting nationalism plays a role in explaining the bias in favor of vaccines developed and produced locally. This public opinion bias on vaccine preferences has significant theoretical and practical implications.

Published: September 2021

Osteochilus melanopleurus can be found in the Siak and Kampar Rivers. The Kampar Rivers waters are better than that of the Siak River and it affects the growth of the fish. The growth pattern is reflected in the pattern of otolith growth rings. The research aims to understand the pattern of otolith growth rings of the O. melanopleurus from both rivers has been conducted from January to February 2021. There were 55 fishes captured (28 males and 27 females). The otolith was taken using tweezers and shaved manually using a soft grindstone. The dark growth ring pattern was investigated using a binocular microscope. Results showed the size of fish captured was 220 to 360 mm from Siak River and 310 to 370 mm from Kampar River. In the fish with the same standard length, the size of the otolith from the Siak River is heavier and longer than that of the Kampar River, which means that fish growth from the Kampar River is better than that of the Siak River. The length of an otolith from Siak River ranged from 1.875 – 3.275 mm, the width was ranged from 1.575–2.75 mm and the weight of otolith was 0.0039 – 0.0098 g, while the length of an otolith from Kampar River ranged from 2.375–3.275 mm, the width was ranged from 1.85–2.575 mm and the weight of otolith was 0.0042 –0.0076 g. The maximum number of the dark ring in the otolith from the Siak River was 4 and Kampar River was 2. The distance between the nucleus and the first dark ring of fish from both rivers was varied from 0.1–0.525 mm, and there was no special pattern. This fact indicates that the first dark ring was formed individually and they were not formed by a periodical incidents during the fish life
