Purpose: This study examines the distribution of income diversification in improving the financial sustainability of private universities amidst difficulties in operational funding during the Covid-19 pandemic with IT Capability moderation. Research design, data and methodology: Closed survey aimed at 468 financial sector leaders from 189 private universities in ten provinces in Indonesia. Results: All income diversification activity variables have a significant positive effect on financial sustainability. In the analysis of liquidity indicators, there are two activities that have a significant positive effect, namely goods and services (β=0.337) and profitable financial management (β=0.124). Furthermore, the results of the solvency indicator test obtained significant positive results in Goods and Services Activities (β=0.337), Commercial Intellectuals (β=0.161), Commercial Contracts (β=0.103), and Profitable Financial Management (β=0.147). The results of the test of higher education growth indicators on three activities have a significant positive effect, namely Goods and Services (β = 0.290), Endowments (β = 0.158), and Commercial Contracts (β = 0.134). The results of the moderation test conclude that IT Capability strengthens the effect of income diversification on financial sustainability. Conclusion: The results of the study as a recommendation for private universities in developing income diversification with information system technology-based management.

The present study aimed to determine the effect of co-pyrolysis of sawdust biomass and scrap tyre waste employing different blending ratios of sawdust to waste tyre such as 100:0, 75:25, 50:50, 25:75, and 0:100. The thermochemical characterization of feedstocks was carried out by employing the proximate, ultimate analysis, and thermogravimetric (TGA) analyses, calorific values, and scanning electron microscope coupled with energy dispersive x-ray analysis (SEM-EDX) to select the blending ratio having better bioenergy potential amongst the studied ratios. The blending ratio of 25:75 (sawdust to waste tyre) was selected for the co-pyrolysis study in a fixed-bed pyrolysis reactor system based on its solid biofuels properties such as heating value (30.18 MJ/kg), and carbon (71.81 wt%) and volatile matter (63.82 wt%) contents. The pyrolysis temperatures were varied as 500, 600 and 700 ℃ while the other parameters such as heating rate and nitrogen flowrate were maintained at 30 ℃/min and 0.5 L/min respectively. The bio-oil yields as 31.9, 47.1 and 61.2 wt%, bio-char yields as 34.5, 34.2 and 31.4 wt% and gaseous product yields as 33.6, 18.60 and 7.3 wt% at the pyrolysis temperatures of 500, 600 and 700 ℃ respectively were obtained. The blends of sawdust and waste tyres showed the improved energy characteristics which could provide the solution for the beneficial management of sawdust and scrape tyre wastes via co-pyrolysis processing.
Adaptive Rule: A Novel Framework for Recommender System

Determining minimum support value on association rule is not easy to users. Hurdles such as data locations and data origins are a mountain that should be overcome by association rule. In addition, rules generated do not necessarily fit user’s needs, thereby, requiring the rules to be put in order based on certain criteria. This paper will discuss a model to produce adaptive rules that originate from a number of different databases, automated threshold determination and rule ranking based on predetermined criteria. The adaptive rule model produced can be implemented in recommender systems in various fields.

Current interest in mathematics learning that focuses on understanding, mathematical reasoning and meaning making underscores the need to develop ways of analyzing classrooms that foster these types of learning. In this paper, the author show that the constructs of social and socio-mathematical norms, which grew out of taking a symbolic interactionist perspective, and Toulmins scheme for argumentation, as elaborated for mathematics education by Krummheuer [The ethnology of argumentation. In: The emergence of mathematical meaning: Interaction in classroom cultures (1995, pp. 229-269). Hillsdale, NJ: Erlbaum], provide us with means to analyze aspects of explanation, justification and argumentation in mathematics classrooms, including means through which they can be fostered. Examples from a variety of classrooms are used to clarify how these notions can inform instruction at all levels, from the elementary grades through university-level mathematics.

Objective The present meta-analysis aimed to analyze the cognitive performance of schizophrenia patients measured by Trail Making Tests (TMT) and the contribution of socio-demographic factors to cognitive impairments. Methods PubMed and PsycARTICLES databases were searched for the studies published between January 1985 and November 2017. Data were drawn from 19 studies encompassing 1095 patients and 324 controls. The effect size and heterogeneity were assessed with Comprehensive Meta-Analysis version 2 using random-effect model. Results Overall, the results showed that the schizophrenia patients performed significantly (p<0.001) worse than healthy controls in both TMT-A and B. However, concurrent substance abuse, clinical status (inpatient or outpatient), duration of education and duration of illness were not associated with cognitive impairment among the schizophrenia patients. Conclusion The present meta-analysis confirmed the cognitive processing speed and flexibility of schizophrenia patients were impaired. However, their duration of education, duration of illness and clinical status (inpatient or outpatient) were not the risk factors.

The study aims to analyze the influence of egoistic, altruistic and biospheric value on green functional benefit, green monetary cost, green satisfaction and green loyalty. The study analyzes the effect of green functional benefit and green monetary cost on green satisfaction and green loyalty, as well as green satisfaction on green loyalty. The study employs quantitative methods with customers who have green brand purchase experience in Indonesia. Non-probability sampling was conducted using purposive sampling method based on predetermined criteria, which are customers who have already purchase and use green brand products. A total of 402 samples were analyzed using Structural Equation Modelling. The result shows that the data support hypotheses on egoistic and biospheric value, hypotheses on green functional benefit effect to green satisfaction and green loyalty, as well as green monetary cost effect to green loyalty. The other hypotheses are not supported by data. As a conclusion, it is egoistic and biospheric value that has positive effect on green loyalty, while green functional benefit and green monetary cost act as mediation between the value orientation and green loyalty. As managerial implication, green brand marketing strategy should incorporate egoistic and biospheric values in messages in advertising and promotion.
