The Philippine gambling industry, and particularly online gaming, has recently emerged as a major driver of the country’s economy. The rise of this controversial industry has become a cause of concern for many Filipino citizens. For the past two decades, Business Process Outsourcing (BPO) has been a major driver of the Philippine economy. However, a new sector of the economy has emerged that appears poised to take over traditional BPOs: online gambling. With the emergence of online gambling, any citizen can simply log into a website and they can play the usual casino games like poker, roulette, and slot machines or even sports betting. Online gambling is just like having a wallet in your pocket right now and just waiting for the money to come in, you just pull out your cellphone and you gamble already right away, that easy. Technically, engaging in online gambling is legal unless operated by a Philippine-licensed offshore company. Unlike other countries, the Philippines does not have strict mandates against gambling. The research aims to cover if consumer attitude and government regulations are significantly proportion with the effect of online gambling behavior. Adding to that, the researcher has added an intervening variable which is promotional ads if it has a direct impact adopting online gambling behavior. By using a quantitative analysis, the study recorded 100 respondents residing in the Philippines and studying their opinion towards this new addictive behavior relating to money. The materials and resources collected have concluded that consumer attitude and government regulations have significant impact towards this unlikely behavior, while promotional ads remain irrelevant.

Coins recognition systems have humungous applications from vending and slot machines to banking and management firms which directly translate to a high volume of research regarding the development of methods for such classification. In recent years, academic research has shifted towards a computer vision approach for sorting coins due to the advancement in the field of deep learning. However, most of the documented work utilizes what is known as ‘Transfer Learning’ in which we reuse a pre-trained model of a fixed architecture as a starting point for our training. While such an approach saves us a lot of time and effort, the generic nature of the pre-trained model can often become a bottleneck for performance on a specialized problem such as coin classification. This study develops a convolutional neural network (CNN) model from scratch and tests it against a widely-used general-purpose architecture known as Googlenet. We have shown in this study by comparing the performance of our model with that of Googlenet (documented in various previous studies) that a more straightforward and specialized architecture is more optimal than a more complex general architecture for the coin classification problem. The model developed in this study is trained and tested on 720 and 180 images of Indian coins of different denominations, respectively. The final accuracy gained by the model is 91.62% on the training data, while the accuracy is 90.55% on the validation data.

The article is devoted to some aspects of card games, and the evolution of casinos in modern Russia. It is shown that in connection with criminalization and other negative phenomena, the gambling business was equated with “alcoholization of the population”. The problem of criminalization could not be solved, since casinos and slot machines migrated largely underground. The internet has become another loophole. In the mid-2000s, the loss of income from casinos to the state budget was a drop in the ocean. After 15 years, the situation has changed. Budget deficits of municipalities have become almost the norm, many subjects of the Federation have become chronic debtors. New non-trivial sources of state and municipal revenues are required. If, taking into account the pros and cons, it turns out to be possible to legalize the gambling business in the country, it should be based on new principles. Among them, locations far from cities, in regional centers, strict state control, a special (but not stifling) tax regime, no credits to players, and wide scale restrictions.

<p>Electronic gaming machines (slot machines) contribute to problem gambling in New Zealand and worldwide. Information displays are one harm minimisation feature of New Zealand electronic gaming machines that has been investigated in recent years. New Zealand gamblers see two types of displays: interruptive pop-up displays after a set period of time has passed, and elective displays if a player presses an information button. These displays inform the gambler about their current session with the intention that they will facilitate informed decisions about continuing play or quitting. The current study used a week-long set of electronic gaming machine data from across New Zealand to run an exploratory investigation into the utility of these information displays. We first observed that fewer than 2% of pop-up displays resulted in people quitting. On this basis it is unlikely that interruptive pop-up displays are meaningfully reducing harm. Our analysis also revealed timing differences in how pop-up displays are scheduled on machines produced by different manufacturers. The likelihood of quitting on a pop-up was influenced by complex interactions of machine and session characteristics, however these effects were small. Secondly, our investigation of elective displays also identified a low rate of access, indicating they are also unlikely to be working effectively as a harm minimisation tool. Analysis revealed players’ likelihood of accessing an elective display was mostly influenced by the venue type they were in and the manufacturer of the machine. Possible recommendations to improve both types of displays include changes to message content, scheduled timing and visual features.</p>

<p>Slot-machine gambling is disproportionately associated with problem gambling. It is therefore important to develop an understanding of how the programming and features of slot machines influence gambling. The current research programme investigated a major feature of many slot machines which has so far been neglected by experimental research – the free-spins bonus feature.  The first major focus of this research was a series of experiments that investigated whether participants prefer to play a slot-machine simulation with a free-spins bonus feature. In each experiment participants gambled on two simulations, one with a free-spins feature and a similar machine without free spins. Following this, participants could switch between the same simulations and the number of spins they made on each simulation was measured. Participants preferred the free-spins simulation, but only when the free-spins feature incorporated an increased rate of wins, music, animations, and graphics advertising the presence of the free-spins feature. In the final experiment investigating preference, we investigated whether responding was influenced by whether participants gambled with hypothetical money, or credit that could be exchanged for tangible rewards. Participants preferred the complex free-spins simulation similarly regardless of what they were gambling with, but selected larger bet amounts and gambled for longer when gambling with hypothetical money.  The second major focus of this research programme was an investigation of whether free-spins features cause increased gambling persistence – a hallmark of disordered gambling. We developed a new persistence-measuring task which was adapted from research investigating Behavioural Momentum Theory. Participants gambled on two simulations in a multiple schedule design. An initial baseline phase consisted of four alternations of each component, one of which had the complex free-spins feature demonstrated to increase preference in the earlier experiments. Baseline phases then alternated with disruption phases where video-clips were embedded into the top right corner of the simulations. The rate at which participants gambled during baseline was compared to the rate at which they gambled when the videos were present, with bigger relative decreases in response rate during the disruption phases indicating less persistence. The free-spins feature did not cause participants to gamble more persistently. Further experiments also assessed whether different frequencies of wins caused participants to gamble more persistently, and results indicated that they did not. The findings of this research programme have implications for Behavioural Momentum Theory, suggesting that comparing response rate during disruption to response rate during baseline is not highly sensitive to small differences in reinforcement schedules. The findings are also relevant for slot-machine legislation, providing an indication that limiting or removing free-spins features may reduce player enjoyment without reducing persistent gambling. Furthermore, the task developed in the persistence investigation provides a useful tool which can be used to investigate how other features of slot machines influence persistence. Future research could, for example, investigate how free-spins features interact with other slot-machine features to influence gambling behaviour.</p>

<p>Slot machines are a remarkably popular mode of gambling even though they are programmed to make a profit by paying out less money than is put in. One common feature of slot machines, which may increase the likelihood of persistent gambling in the face of this monetary loss, is the near win. This study’s aim was to investigate the conditioned reinforcing properties of near wins using an observing response procedure in the context of a simulated slot machine. In an observing response procedure, participants can use an observing button to produce a stimulus correlated with the availability of reinforcement (S+) or a stimulus correlated with no reinforcement or less reinforcement (S-). The percentage of observing responses made for each stimulus is thought to reflect the reinforcing efficacy of the reinforcer correlated with each stimulus. Experiment 1 successfully tested the procedure with an obvious reinforcer - wins - and found consistently more observing for the S+. In Experiment 2 and 3 the S+ was correlated with near wins, and in Experiment 2 only those with slot-machine experience had consistently more observing for the S+. Experiment 3 increased the probability of wins to enhance the reinforcing efficacy of near wins, but failed to find consistently more observing for the S+, regardless of slot machine or scratchie card experience. These results indicated that near wins are not conditioned reinforcers. However, participants tended to bet more following near wins than losses, which suggested that near wins may instead function as discriminative stimuli.</p>

Since the slot opening is large in the uniform slot machine, the torque ripple generated by overlapping or misaligning with the rotor cavity is remarkably large in the case of interior permanent magnet (IPM) machine. In this work, it is observed that the magnitude of torque ripple depends strongly on the phase difference between air-gap field harmonics: The ripple is minimized when the two dominant harmonic components cancel each other. Based on this fact, a condition is developed to minimize torque ripple by adjusting the q-flux channel width and d-flux barrier width. The torque ripple minimizing solution is found from a level chart made by subdomain time-stepping analysis. Finite element analysis (FEA) also gives a very similar minimizing solution. A prototype machine is manufactured, and its performances are validated through experiments.
