Sequential Temporal Discrimination in Humans and Mice
Authors: Çoşkun Filiz , Berkay Dilara , Sayalı Zeynep Ceyda , Balcı Fuat
Published: March 2021

Previous studies showed that humans and mice can maximize their rewards in two alternative temporal discrimination tasks by incorporating exogenous probabilities and endogenous timing uncertainty into their decisions. The current study investigated if the probabilistic relations modulated the temporal discrimination performance in scenarios with more than two temporal options. In order to address this question, we tested humans (Experiment 1) and mice (Experiment 2) in the dual-switch task, which required subjects to discriminate three time intervals (short, medium, and long durations) in a sequential fashion. The latencies of switches from short to medium and from medium to long option were the main units of analysis. The results revealed that the timing of switches between the first two options (short-to-medium) were sensitive to probabilistic information in both humans and mice. However, mice but not humans adapted the timing of their subsequent switches between the last two options (medium-to-long) based on the probabilistic information associated with these latter options. These results point at a suboptimal tendency in the temporal decisions of humans with multiple options.
A Need for Individual Data Analyses for Assessments of Temporal Control: Invertebrate Fixed Interval Performance
Authors: Craig David Philip Arthur , Abramson Charles I.
Published: March 2021

We outline several experimental variables and addressed the inconsistencies of these variables within the invertebrate fixed interval literature. We posit previous inconsistencies within the invertebrate fixed interval literature may be due to the utilization of aggregate versus individual analyses and contend individual analyses are critical in order for conclusions to be made about species’ abilities to emit responses that can come under temporal control. To exemplify these statements, we exposed honey bees Apis mellifera lingustica (N=13) to either an FI 15-sec or FI 30-sec schedule of reinforcement and analyzed subjects’ cumulative response records, response bin levels, quarter lives, inter-response time patterns, response duration patterns, and trial durations. No measures clearly indicated individual subjects’ responding came under temporal control of the fixed interval schedules; however, pooled group analyses did produce seemingly clear evidence of temporal control.

Published: March 2021

Indonesia memiliki keanekaragaman kebudayaan hasil dari warisan nenek moyang terdahulu dengan nilai-nilai luhur di dalamnya. Budaya yang sesuai dengan nilai-nilai karakter bermartabat menjadi salah satu sumber nilai yang termuat dalam pendidikan karakter bangsa Indonesia. Salah satu budaya bangsa Indonesia yang memuat pendidikan karakter adalah permainan tradisional. Namun, anak-anak sekarang lebih banyak bermain permainan digital dibandingkan permainan tradisional. Hal ini dikarenakan permainan tradisional sudah asing di telinga generasi muda disebabkan generasi mereka sebelumnya meninggalkan permainan tradisional tersebut sejak mengenal permainan digital. Padahal, permainan tradisional banyak memuat pendidikan karakter dibandingkan permainan digital. Di lain sisi, dunia pendidikan pada masa pandemi yang dilakukan dengan pembelajaran jarak jauh membuat penanaman pendidikan karakter pada anak dianggap minim. Padahal, fungsi pendidikan adalah pembentukan nilai karakter dimana Indonesia memiliki 18 nilai karakter. Menanggapi hal tersebut, salah satu wujud melestarikan permainan tradisional yang memuat pendidikan karakter yaitu dengan dibuatnya inovasi MANTRA (Permainan Tradisional). MANTRA merupakan aplikasi android yang memberikan informasi berbagai permainan tradisional di Indonesia dan dilengkapi dengan adanya fitur Pesan, fitur Buat Grup, fitur Tentang MANTRA, fitur Pengaturan, fitur Pilih Permainanmu, fitur Info, fitur Ayo Main, dan fitur Ulasan. Sehingga tujuan penelitian ini yaitu menjelaskan konsep penerapan MANTRA (Permainan Tradisional) sebagai sarana penanaman pendidikan karakter melalui pelestarian kebudayaan bangsa. Metode penelitian yang digunakan adalah metode deskriptif dengan menggunakan data kualitatif. Teknik pengumpulan data menggunakan teknik analisis data dari literatur yang terkait. Harapannya, dengan fitur yang ditawarkan MANTRA dan peran berbagai pihak, maka dapat terbentuk generasi muda yang unggul dan luhur dan lestarinya kebudayaan bangsa khususnya permainan tradisional.

Authors: Zhu Jing , Deng Aidong , Zhang Shun , Ding Xue , Xue Shuo
Published: March 2021

When deep learning is used for rolling bearing fault diagnosis, there are problems of high model complexity, time-consuming, and large memory. In order to solve this problem. This paper presents an intelligent diagnosis method of rolling bearings based on VMD-CWT feature extraction and MobileNet, VMD is used to extract the signal features, and then wavelet transform is used to extract the timefrequency features. After the image is enhanced, the MobileNet network is trained. In order to accelerate the convergence speed, this paper adds transfer learning in the network training process, and migrates the weights of the first several layers pretrained to the corresponding network. Experimental results based on bearing fault data sets show that after adopting VMD-CWT, the accuracy of mobilenet increased from 68.7% to 94%, and its network parameters were reduced by an order of magnitude compared with CNN.

Authors: Zheng Zhihao , Zhang Yao , Gurram Vinay , Salazar Useche Jose , Roth Isabella , Hu Yi
Published: March 2021

At present, the development and innovation in any business/engineering field are inseparable from the computer and network infrastructure that supports the core business. The world has been turning into an era of rapid development of information technology. Every year, there are more individuals and companies that start using cloud storages and other cloud services for computing and information storage. Therefore, the security of sensitive information in cloud becomes a very important challenge that needs to be addressed. The cloud authentication is a special form of authentication for today’s enterprise IT infrastructure. Cloud applications communicate with the LDAP server which could be an on-premises directory server or an identity management service running on cloud. Due to the complex nature of cloud authentication, an effective and fast authentication scheme is required for successful cloud applications. In this study, we designed several cloud authorization schemes to integrate an onpremises or cloud-based directory service with a cloud application. We also discussed the pros and cons of different approaches to illustrate the best practices on this topic.
Investigating Data Sharing in Speech Recognition for an Under-Resourced Language: The Case of Algerian Dialect
Authors: Amine Menacer Mohamed , Smaïli Kamel
Published: March 2021

The Arabic language has many varieties, including its standard form, Modern Standard Arabic (MSA), and its spoken forms, namely the dialects. Those dialects are representative examples of under-resourced languages for which automatic speech recognition is considered as an unresolved issue. To address this issue, we recorded several hours of spoken Algerian dialect and used them to train a baseline model. This model was boosted afterwards by taking advantage of other languages that impact this dialect by integrating their data in one large corpus and by investigating three approaches: multilingual training, multitask learning and transfer learning. The best performance was achieved using a limited and balanced amount of acoustic data from each additional language, as compared to the data size of the studied dialect. This approach led to an improvement of 3.8% in terms of word error rate in comparison to the baseline system trained only on the dialect data.
An Analysis of Consumption Function: A Case Study of Upper Middle Income Economies
Authors: Et al., Sarfaraz Ahmed Shaikh
Published: March 2021

This paper draws on evidence of consumption function from four-country group case-studies of upper middle-income economies (together termed as developing economies). The ARDL model is applied to the time series data from 1985 to 2017 to understand the major components of the aggregate consumption function. The result reveals that labor income and wealth impact in all economies are similar and have a significant positive impact on real private aggregate consumption. Similarly, the real interest rate and unemployment have an analogous effect on real private aggregate consumption. The real interest rate has a negative effect on aggregate real private consumption supporting income effect. In the short run real GDP and wealth have a positive impact on aggregate real private consumption while real interest rate and unemployment rate have a negative effect on aggregate real private consumption for selected economies. Moreover, overall PIH is valid for long-run, while AIH is valid for short-run in the selected countries.
Impact of Islamic Label on Firm’s Governance: Evidence from Pakistan
Authors: Et al., Naeem Ullah
Published: March 2021

This paper aims to study the impact of Islamic Label on the firm’s governance quality. The recent literature indicates that debt can discipline managers to work efficiently in the interest of the firm. Thus low leverage can proxy for good governance. Since Islamic firms are low on debt, thus we may extend that Islamic label can proxy for good governance. To test our hypothesis, we obtained data from 231 nonfinancial firms listed on Pakistan stock exchange out of which 53 were declared as sharia-compliant. The results indicate that the Islamic label has a positive significant impact on a firm’s governance quality and Islamic label can proxy for good governance. This study aims to form a nexus between Islamic label, leverage, and governance on which there is little or no literature. It will also be important for investors and managers of Islamic funds who have little or no research support about the governance aspect of Islamic firms.

Authors: Et al., Habib Elahi
Published: March 2021

The education system in Pakistan does not cater to the need of the society especially inculcating the unity of thought, skills, and attitudes among the learners. The serious efforts to improve the standard of Higher Education for the commercialization of education especially higher education have not been made by the government. A number of policies were framed for the betterment of the education system but there could not be a single unanimous policy framed and materialized. Pakistan is a country that has invested meager resources in the education sector. The countries which invested in the human resource are now leading the economic arena and are counted as developed countries. With the reasonable allocation of funds and expertise in this field, the priorities can be fixed to correlate with the standards of the higher education of developed countries. Higher Education Commission or the like bodies of developed countries have played a pivotal role in making their educational standards and these are role model for Pakistan. In this respect, some practical suggestions are recommended for enhancing the marketability and commercialization of education in Pakistan.

Published: March 2021

In this study, the sample of newly IPO firms at PSX from 2000 to 2018 is selected to observe the performance in the long run, under different maturity level. The analysis is based on Jensen’s alpha obtained through CAPM, four factors (4-F), and three factors model (3-F). Based on the analysis of Jensen’s alpha, the underpricing of IPOs disappeared after the periods of one to three years to suggest that investors can not earn risk-adjusted positive returns accounting for market, momentum, value and size factors. In the analysis of GCT regression model, for the three different maturity level, the severe underperformance of these new firms are to be observed. Further, the result of new firms through GCT model show that different maturity (1-5 years, 6-10 years, and more than 10 years) of firms do not matter, and overall newly firms underperform in long run.

The objective of the current study is to investigate the impact of business strategies on the future crash risk of stock prices by considering the role of overvalued equity. This relationship is checked by taking non-financial firms from Pakistan Stock Exchange from 2008-2016. To evaluate the business strategy, composite strategy score is used which considers the firm's development and research costs to look for new products, sales ratio to determine the firm’s capacity to manufacture the product efficiently, standard deviation of employees, sales growth, marketing expense to sales ratio to locate the firms’ emphasis on marketing, and intensity of assets expenditures to capture the firms’ emphasis on production. Market to book decomposition method is used to calculate the equity overvaluation whereas the negative conditional skewness is used as a measure of crash risk. Random and fixed effect panel regression models are used to estimate the results. The results of the present study indicate that firms pursuing innovative strategies have a higher probability to face crash price risk. Outcomes of the study also confirm that such strategies also increase the likelihood of equity overvaluation which increases the risk of stock price crash in the future. The results of the current study are helpful for the investors in allocating the assets cautiously among companies with diverse strategies.

After that, these hypotheses are tested through the questionnaires which are distributed to individual equity investors at Pakistan’s Stock Exchanges. Then the collected data are analyzed by using Exploratory Factor Analysis (EFA), Cronbach’s Alpha, Pearson Correlation Coefficient and Multiple Linear Regression (MLR) tests. The results show that there are two mainly behavioral factors: Heuristic Theory (Overconfidence Bias) and Prospect Theory (Loss Aversion Bias), affecting the investment decisions making process and performance of individual equity investors. Most of the sub-variables of both behavioral biases directly contain positive impact. But, when the mediating variable: decision making process was used; these biases contain high positive impact on the performance of equity investors which concludes the better decision-making ability of investors help them to improve their performance.
