Abstract. Cartographic maps are a form of communication. Through signs and symbols, they give rise to ideas and thoughts of geospatial phenomena, enabling us to relate to, think about, and to imagine events from a viewpoint beyond direct experience. By applying a mutually shared set of signs and semiotic rules, sheer unlimited, meaningful, novel messages about space and time can be communicated through maps. As such, maps are considered a means of conceiving, articulating, and structuring the human world (Harley, 1989).Maps are human-made artifacts, based on a myriad of choices concerning what to communicate and how to communicate. Maps are, therefore, never neutral but based on decisions which will influence how maps are perceived, how information is interpreted, and how phenomena and events are imagined (Chandler, 2007; Monmonier, 1996). Cartographic communication, therefore, requires deliberate choices to share and express information successfully. To this day, the cartographer faces the challenge of near-infinite variations of visual variables to choose from. Yet, which ones are most suitable for a given context, for a given type of spatial information, object, or phenomenon? The choice for the aptest cartographic signifier is still a challenging task. In cartography, there remains a need for a differentiated understanding of how visual variables can be used to encode information (MacEachren et al., 2012).While all map signs can be considered to be identifiers which aim to denote and inform about spatial phenomena, research from related fields show that signs and symbols may also imbue connotative qualities that influence human affect and modulate cognitive processes (e.g. Feldman Barrett et al., 2007; Loftus & Palmer, 1974). In as far as cartographic semiology provides a theoretical framework addressing the denoting qualities of cartographic visual variables (Bertin, 1974), it, hitherto, does not encompass their connotative effects on human affect, perception, and cognition. At the same time, empirical research on the connotative meaning of map signs is still scarce, and semiotic differentiations between the denoting and connoting qualities of signifiers are often neglected in cartographic research and applications of semiotics. Consequently, “the difference of what a map sign means and what it represents has become blurred” (MacEachren, 1995, p.245).Between the intersection of psychology, cartography, and semiotics, this research draws attention to the connotative qualities of shape symbols in cartographic communication. In qualitative and quantitative empirical studies, abstract map symbols are studied in cartographic and non-cartographic contexts, and their connotative effects on human judgments and affective responses are explored (Klettner, 2019, 2020). Shape symbols, in these studies, refer to commonly used graphic variables in visual communication and thematic cartography (e.g. circle, triangle, square, etc.) to indicate nominal data. Findings strongly indicate that some map symbols do not only depict and denote but also express and connote and that these connotative qualities can be as powerful as to modulate affective responses and cognitive processes, such as influencing judgments about the depicted phenomena.A better understanding of how map signs and symbols are perceived can allow for more accurate discrimination between them. By unraveling some of the connotative qualities of cartographic point symbols, this research aims to contribute towards more informed choices and towards creating more effective and associative cartographic visualizations.

The Difference

The auditing “expectation gap” refers to the difference between (1) what the public and other financial statement users perceive auditors' responsibilities to be and (2) what auditors believe their responsibilities entail. The notion of this divergence receives much attention in the accounting literature (i.e., Commission on Auditors' Responsibilities 1978; Guy and Sullivan 1988; AICPA 1993; U.S. Government Accounting Office 1996). Although prior empirical studies encompass certain expectations associated with a range of audit services, these papers often involve the opinions of bankers as the primary user group employed in the research (Nair and Rittenberg 1987; Lowe and Pany 1995). In contrast, this study extends the prior research by directly comparing audit partners' and investors' perceptions of auditors' responsibilities involving various dimensions of the attest function. We conducted the study to determine if an expectation gap currently exists and we find that it does; investors have higher expectations for various facets and/or assurances of the audit than do auditors. Our findings serve as evidence that the accounting profession should engage in appropriate measures to reduce this expectation gap.

Abstract How can one assess which countries select more experienced leaders for the highest office? There is wide variation in prior career paths of national leaders within, and even more so between, regime types. It is therefore challenging to obtain a truly comparative measure of political experience; empirical studies have to rely on proxies instead. This article proposes PolEx, a measure of political experience that abstracts away from the details of career paths and generalizes based on the duration, quality and breadth of an individual's experience in politics. The analysis draws on a novel data set of around 2,000 leaders from 1950 to 2017 and uses a Bayesian latent variable model to estimate PolEx. The article illustrates how the new measure can be used comparatively to assess whether democracies select more experienced leaders. The authors find that while on average they do, the difference with non-democracies has declined dramatically since the early 2000s. Future research may leverage PolEx to investigate the role of prior political experience in, for example, policy making and crisis management.

Hyperspectral (HS) images usually have high spectral resolution and low spatial resolution (LSR). However, multispectral (MS) images have high spatial resolution (HSR) and low spectral resolution. HS–MS image fusion technology can combine both advantages, which is beneficial for accurate feature classification. Nevertheless, heterogeneous sensors always have temporal differences between LSR-HS and HSR-MS images in the real cases, which means that the classical fusion methods cannot get effective results. For this problem, we present a fusion method via spectral unmixing and image mask. Considering the difference between the two images, we firstly extracted the endmembers and their corresponding positions from the invariant regions of LSR-HS images. Then we can get the endmembers of HSR-MS images based on the theory that HSR-MS images and LSR-HS images are the spectral and spatial degradation from HSR-HS images, respectively. The fusion image is obtained by two result matrices. Series experimental results on simulated and real datasets substantiated the effectiveness of our method both quantitatively and visually.

Main Consumer

The article reflects the author’s position on the adjustment of the so-called substitution bias, which affects the value of the consumer price index, currently calculated using the Laspeyres formula. The author proposes a solution to the problem of the adequacy of statistical measurements of the dynamics of consumer prices in the case when, as a result of changing cost of the consumer basket, a buyer replaces a relatively expensive product with a relatively cheaper one. This solution is based on the existing index construction methodology (axiomatic, economic and stochastic approaches). The article substantiates the use of the Törnqvist formula, which has better properties in comparison with other formulae used in the construction of superlative indices. The authors calculated the Törnqvist price index for Russia based on Rosstat methodology and data using country-level quarterly group price indices and shares of consumer spending. To evaluate the results of empirical testing Laspeyres price index was compiled using the same quarterly data as the Törnqvist index. The values of the Törnqvist price index in most cases are less than the price dynamics obtained according to the Laspeyres formula. This conclusion is proved both theoretically and empirically, and it is confirmed for Russia as well. However, due to the non-observance of the conditions of smooth trends in consumer prices, the difference between the values of the Törnqvist and Laspeyres indices is significantly larger in certain quarters than that presented in empirical studies in other countries. Consumer price index, calculated using the Törnqvist formula, in the system of indicators of price statistics in Russia can be defined as an indicator that specifies the main consumer price index. Calculation of its value is necessary for a more realistic description of the processes taking place in the consumer market.

<p><strong>Abstract.</strong> Reading spatial information from topographic maps to form mental representations that guide spatial orientation and navigation is a rather complex cognitive process. Perceptual and knowledge-driven processes interact to support the map reader in building these mental representations. The resulting cognitive maps are not one-to-one mappings of the spatial information and known to be distorted systematically. It is assumed that spatial information is hierarchically organized in these mental models. We are interested in how map design based on cognitive principles supports memory formation and leads to less distorted mental representations.</p><p>Based on the results of empirical studies we are able to show that overlaid grids in these maps address the hierarchical nature of these mental representations of map space. When map users are asked to learn object locations in a map the availability of overlaid grid layers improve object location memory. This effect is independent of the shape of these grid patterns (square grids or hexagonal grids) and, moreover, can be shown to be effective even in situations where the grids are interrupted by other maps layers (i.e. so-called illusory grids).</p><p>These results seem best explained by the formation of less distorted mental representations based on the availability of superordinate hierarchical information and the application of Gestalt principles by the map user. Thus again, point to the interaction between perceptual and knowledge-driven processes in the formation of these mental representations of map space. This assumption receives further support by eye-tracking data that reveal that grids do not only attract attention towards their own location but also seem to structure the gaze patterns in relation to the relevant object locations that are not necessarily located close to a grid line.</p>

Penelitian ini bertujuan untuk menganalisis seberapa maksimal proses kebijakan retrukturisasi Kredit UMKM dalam Pemulihan Ekonomi di Masa Pandemi Covid-19. Kondisi perekonomian global sedang mengalami goncangan hebat akibat mewabahnya Covid-19. Dampak dari pandemic ini sangat mempengaruhi segala aspek terutama pada kondisi Kesehatan dan perekonomian suatu negara, tidak terkecuali Indonesia. Secara keseluruhan, hampir semua sektor industry mengalami goncangan dan tidak terkecuali sektor UMKM. Maka dari itu dikeluarkanlah kebijakan retrukturisasi Kredit UMKM guna mendorong optimalisasi fungsi intermediasi pada perbankan dan menjaga stabilitas sistem keuangan serta mendukung pertumbuhan perekonomian. Program restrukturisasi kredit menjadi program dari OJK yang dapat diterapkan oleh perbankan kepada UMKM. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan menggunakan studi empiris dari penelitian terdahulu serta peraturan-peraturan terkait dengan restrukturisasi kredit yang dikeluarkan oleh Otoritas Jasa Keuangan. Hasil penelitian ini menunjukkan bahwa implementasi kebijakan restrukturisai kredit bagi UMKM sudah berjalan dan digunakan oleh para pelaku UMKM. Kemudian berdasarkan implementasinya kebijakan ini merupakan kebijakan top-down dimana memerlukan banyak Lembaga untuk bekerja sama dan keputusan berasal dari Peraturan pemerintah baru di teruskan ke Lembaga-lembaga lain di bawahnya hingga informasinya sampai dan bisa dirasakan oleh para UMKM.  This research aims to analyze the policy of restructuring SMEs Credit in Economic Recovery during the Covid-19 Pandemic. The global economy is experiencing severe shocks due to the outbreak of Covid-19. The impact of this pandemic greatly affects all aspects, especially on the health and economic condition of a country, not least Indonesia. Overall, almost all industry sectors are experiencing shocks and are no exception to the SMEs sector. Therefore, the policy of restructuring SMEs Credit was issued to encourage optimization of intermediation function in banking and maintain the financial system stability and support economic growth. Credit restructuring program becomes a program from OJK that can be applied by banks to SMEs. The method used in this research is a qualitative method using empirical studies from previous research as well as regulations related to credit restructuring issued by the Financial Services Authority. The results of this research show that the implementation of credit restructuring policy for SMEs is already running and used by SMEs. Then based on the difference in implementation of this policy is a top-down policy that requires many Institutions to cooperate and decisions derived from the new government regulations are forwarded to other institutions under it until the information reaches and can be felt by SMEs.

In this study, the consumer types were divided into two groups: power and powerless. First, depending on the sense of power, the interaction effect between power and powerless was verified based on two types of weather: sunny and cloudy. Secondly, the purchase intention of luxury goods was examined as a dependent variable and the difference in purchase behavior patterns were observed. Lastly, based on the mood-congruent effect of consumer purchase intentions, it was confirmed that power influences weather, and the weather and mood are influenced by each other, as also manifested in empirical studies. In particular, the power group had a more significant effect than the powerless group, and the positive mood and weather played a big role for consumers’ intention to purchase luxury goods. Therefore, this study can contribute both theoretically and practically to prepare appropriate marketing strategy plans based on weather and consumer roles—power and powerless.

Vegetation height is an important parameter in monitoring peatlands. Vegetation height can be estimated using remote sensing. Vegetation height can be estimated by utilizing DSM and DTM. The data that can be used are LiDAR, X-SAR, and SRTM C. In this study, LiDAR data is used for DSM2018 and DTM2018 extraction. The purpose of this research is to detect the vegetation height in Central Kalimantan peatlands using remote sensing technology. The research location is in Bakengbongkei, Kalampangan, Central Kalimantan. The integration of X-SAR and SRTM C is used for DSM2000 and DTM2000 extraction. DSM2000, DTM2000, DSM2018, and DTM2018 performed height error correction with tolerance of 1.96? (95%). Then do the geoid undulation correction to EGM2008. The results obtained are DSM and DTM with a similar height reference field. If it meets these conditions it can be calculated the vegetation height estimation. Vegetation height can be obtained using the Differential DEM method. The Changing in vegetation height from 2000 to 2018 can be estimated from the difference in vegetation height from 2000 to vegetation height in 2018. Results of spatial information on vegetation height and its changes need to be tested for the accuracy. This accuracy-test includes a cross section test, height difference test, and comparison with measurements of vegetation height in the field. The results of this research can be used to monitor the changing the vegetation height in peatlands.

Asymmetrical neural networks are shown in the biological neural network as the catfish retina. Horizontal and bipolar cell responses are linearly related to the input modulation of light, while amacrine cells work linearly and nonlinearly in their responses. These cells make asymmetrical neural networks in the retina. Several mechanisms have been proposed for the detection of motion in biological system. To make clear the difference among asymmetrical networks, we applied non-linear analysis developed by N. Wiener. Then, we can derive α-equation of movement, which shows the direction of movement. During the movement, we also can derive the movement equation, which implies that the movement holds regardless of the parameter α. By analyzing the biological asymmetric neural networks, it is shown that the asymmetric networks are excellent in the ability of spatial information processing on the retinal level. Then, the symmetric network was discussed by applying the non-linear analysis. In the symmetric neural network, it was suggested that memory function is needed to perceive the movement.

Multiple Sleep Latency

The less rigid architecture of sleep in patients with narcolepsy type 1 (NT1) compared with healthy subjects may provide new insights into some unresolved issues of dream experience (DE), under the assumption that their DE frequencies are comparable. The multiple transition from wakefulness to REM sleep (sleep onset REM period: SOREMP) during the five trials of the Multiple Sleep Latency Test (MSLT) appears of particular interest. In MSLT studies, NT1 patients reported a DE after about 80% of SOREMP naps (as often as after nighttime REM sleep of themselves and healthy subjects), but only after about 30% of NREM naps compared to 60% of daytime and nighttime NREM sleep of healthy subjects. To estimate accurately the “real” DE frequency, we asked participants to report DE (“dream”) after each MSLT nap and, in case of failure, to specify if they were unable to retrieve any content (“white dream”) or DE did not occur (“no-dream”). The proportions of dreams, white dreams, and no dreams and the indicators of structural organization of DEs reported after NREM naps by 17 adult NT1 patients were compared with those reported by 25 subjects with subjective complaints of excessive daytime sleepiness (sc-EDS), who take multiple daytime NREM naps. Findings were consistent with the hypothesis of a failure in recall after awakening rather than in generation during sleep: white dreams were more frequent in NT1 patients than in sc-EDS subjects (42.86 vs 17.64%), while their frequency of dreams plus white dreams were similar (67.86 and 61.78%) and comparable with that of NREM-DEs in healthy subjects. The longer and more complex NREM-DEs of NT1 patients compared with sc-EDS subjects suggest that the difficulty in DE reporting depends on their negative attitude toward recall of contents less vivid and bizarre than those they usually retrieve after daytime SOREMP and nighttime REM sleep. As this attitude may be reversed by some recall training before MSLT, collecting wider amounts of DE reports after NREM naps would cast light on both the across-stage continuity in the functioning of cognitive processes underlying DE and the difference in content and structural organization of SOREM-DEs preceded by N1 or also N2 sleep.
