The highly prized black truffle (Tuber melanosporum) has become a model species for ectomycorrhizal fungi biology. However, several questions concerning its reproductive phase remain unanswered. To provide new hypotheses on the fruitbody formation process, we have explored the causal links among development characters of black truffle fruitbodies that are primarily linked to either the mating process, fruitbody growing stage, or maturation. Path analysis was applied to test causal models outlining the relationships among fruitbody development characters such as fruiting depth, weight, shape, and spore maturity. These characters were investigated over a two-season survey and three soil typologies (plus peat-based substrate) under irrigated conditions. We found a clear and generalized relationship between fruitbody weight and shape. Among clusters of fruitbodies we found a positive relationship between the weight of the largest fruitbody and the weight of the remaining fruitbodies. However, no generalized relationships among characters linked to different development stages appeared. Our results were noticeably consistent across soil typologies, both for fruitbodies growing singly and in clusters, indicating that early-developing fruitbody characters did not influence characters linked to subsequent morphogenetic stages. The lack of links among stages opens new perspectives for pre-harvest quality management with stage-specific cultivation practices.

This study aims to determine the effect of Total Quality Management (TQM) on employee productive behavior and company performance at PT. Tomorrow’s Antiques Indonesia. This study uses a quantitative method with a sample of 104 employees. Data was collected by observation, interviews, documentation, literature, and questionnaires. The analysis technique used descriptive analysis, path analysis (analysis path), and sobell test. The results of the total quality management (TQM) research have a positive and significant effect on employee productive behaviour at PT. Tomorrow's Antiques with coefficient of 0.986 and a sig value of 0.00 <0.05; employee productive behavior has a positive and significant effect on company performance at PT. Tomorrow's Antiques with coefficient of 0.606 and a sig value of 0.00 <0.05; total quality management (TQM) has a positive and significant effect on company performance at PT. Tomorrow's Antiques with coefficient of 0.396 and a sig value of 0.00 <0.05, and employee productive behaviour can mediate the effect of total quality management (TQM) on company performance at PT. Tomorrow's Antiques with Z value (17,311) > Z table (1,96).

Quality Management Practices

Micro, Small and medium-sized enterprises (MSMEs) are important to national development as they produce a huge percentage of the national output and provide an even greater proportion of employment. They play a significant role in economic growth, innovation, poverty alleviation and raise standard of living.  Research has shown that most manufacturing SMEs that adopt and implement TQM practices exhibited a significant positive relationship and confirmed that TQM practices are indicators of firm performance.  The study examines the benefits of TQM implementation, and the challenges these manufacturing SMEs face in their attempt to implement TQM practices.  The study which was exploratory in nature used descriptive survey and a structured interview to collect data from the SMEs who were purposively selected for the interview.  The study purposively selected fifty (50) owner-managers for the interview, but due to the COVID-19 health pandemic, only five (5) participated in the interview.  A sample size of 5 respondents were selected for exploratory study in Accra metropolitan area of the Greater Accra region to respond to the interview instrument.   The tool for qualitative data analysis was NVivo version 11.  The study discovered that manufacturing SMEs adopted and implemented TQM practices in their organisations. The TQM practices which were analysed were: organisational leadership; strategic planning and development; customer focus; human resource focus; continuous improvement and process management.  The study established that effective implementation of TQM practices led to financial performance of these manufacturing SMEs as there was a significant positive relationship between the TQM practices and firm performance.   The study although confirmed a direct positive relationship between quality management practices and firm performance, there were numerous challenges that serves as barriers to TQM implementation in the organisations. The challenge of downsizing was the most reported among the SMEs.  It is recommended that manufacturers in the SME sector must be aware of the prospects of quality management practices since the success of its implementation depends largely on its awareness.  It is also recommended that SMEs identifies challenges that face its implementation of TQM, so as to eliminate any barrier to its implementation.

The Relationship

The development of Islamic economics in banking practices in society develops innovatively. Various sharia banking products have become the people's choice in supporting their daily economic activities. The same thing also happened to students. The purpose of study is to analyze the religiosity effect of students' interest in saving for Islamic banking with knowledge as intervening variable. Multiple linear regression is an analytical technique used here, with hypothesis testing and path analysis to support its conclusions. The result of this study is that the level of religiosity significantly effects on students' interest in saving for Islamic banking with positive relationship. Likewise, knowledge is able mediate the relationship between the religiosity variable and students' interest in saving.

Collective Influence

Although soil is one of the factors in the biology of Tuber melanosporum (black truffle of Périgord), which has been the subject of much study, there are few quantitative analyses relating to its effects on carpophore production. The aim of this work is to establish the statistical relationship between T. melanosporum productivity in 20 soil surface horizons and their conventional soil properties (granulometric texture, pH, calcareous fractions, organic carbon, total nitrogen, exchangeable cations). The study area is situated in the centre of the Iberian Peninsula under a Mediterranean climate. Statistical analysis shows that the collective influence of these conventional soil features is low, as principal component analysis explains only 27% of the variance in T. melanosporum production. However, a high percentage of active limestone (calcium carbonate extractable with ammonium oxalate) accounts for 40% of the variance in T. melanosporum production. Active limestone is very important to T. melanosporum because it regulates soil pH and exchangeable Ca2+ availability and participates in the organisation and maintenance of the soil structure; it also plays a role in the truffle’s nutrition. These results obtained for active limestone may be of use in truffle cultivation.
