Experimental Study on the Crushing Properties of Corn Stalks in Square Bales

With the development of straw baling mechanization technology, straw is stored in the form of square baling or round baling. At present, hammer mill or the guilt-cutting and rubbing combined mill is widely used to crush square bales of straw. These two kinds of crushing equipment have disadvantages such as low productivity, large power consumption, and poor crushing effect. This paper aims to study and analyze the crushing characteristics of square baled straw after unbaling, and lay a theoretical foundation for the later research and development of a special square baled straw crusher with high productivity, low power consumption, good crushing effect, and the simulation of the square baled corn straw crushing process. For this purpose, this study carried out a corn bale crushing experiment on the Instron 8801 fatigue test machine, and studied the effects of blade angle, water content and loading speed on corn bale crushing force through the response surface method. Test results showed that the crushing process includes the compression stage and shearing stage; in terms of single factor effect, with the increase in water content and blade angle, the crushing force of the corn bale increased, but the loading speed had no significant effect on the crushing force of the corn bale. In terms of interaction effect, there was interaction effect between moisture content and blade inclination angle, when moisture content was 10%, with the increase in blade inclination angle, the incremental speed of the crushing force also increased gradually. When the blade inclination angle was 10°, with the increase in moisture content, the incremental speed of the crushing force also increased, and the interaction effect of them jointly acted on the crushing force of the corn bales.

The mediation of matchmaking: a comparative study of gender and generational preference in online dating websites and offline blind date markets in Chengdu

Online dating has modernized traditional partner search methods, allowing individuals to seek a partner that aligns with their preferences for attributes such as age, height, location, or education. Yet traditional forms of partner selection still exist, with continued parental involvement in the matching process. In this paper, we exploit different matchmaking methods with varying degrees of youth autonomy versus parental involvement. We use a unique dataset collected in Chengdu, China, where profiles from the blind date market (n = 158) capture parental preferences and profiles from an online dating website (n = 500) capture individual preferences. Regarding gender, we find that men generally display a desire for women younger, shorter, and less educated than themselves, while women desire older and taller men of the same education as themselves. With regards to parental influences, we find parents specify a narrower range of accepted partner attributes. Further, we find an interaction effect between gender and generational influences: the preferences of parents advertising their daughters on the blind date market show a greater discrepancy in attribute preferences to the online daters than parents advertising their sons.

The Effect of Economic Crises on Japan’s Bilateral Trade Distribution: Examination of the Tohoku Earthquake Impact on African Markets

This paper examines the Japanese International Bilateral Trade Flow (JIBTF) in relation to economic crises, such as the Tohoku earthquake, and focuses on changes in the Distribution Networks of JIBTF (DNoJ) concerning African countries and Japanese Major Trade Partners (JMTP). The Harmonized System 6-digit level (“total” and product level) panel data from 2001 to 2019 are analyzed by employing the (structural) gravity method. First, the results of the study find that the Tohoku earthquake, compared to the 2008 crisis, has a stronger negative impact on the JIBTF and affects the DNoJ among Japanese trade partners. Second, the results prove that Japanese trade intention with African markets decreases relatively. In other words, exporting to African countries has a negative interaction effect after 2015. On the contrary, this interaction effect on JMTP comparatively increases; thus, Japan relocates its export to other markets such as JMTP. The Tohoku earthquake shaped the JIBTF to be more integrated with the Asia-Pacific and the EU regions, instead of African markets.JEL Classification Codes: F10, F14, C23, C24

An Islamic Form of Logotherapy in the Treatment of Depression, Anxiety and Stress Symptoms in University Students in Iran

Previous research demonstrated that spiritually sensitive psychotherapy is an effective treatment for clients with depression or anxiety, with outcomes equivalent to secular control interventions. The goal of this study was to evaluate the efficacy of spiritually sensitive logotherapy intervention in the treatment of depression, anxiety, and stress symptoms in university students in Iran. Sixty students with elevated depression symptoms (Beck Depression Inventory II, BDI-II, 22 or greater) were randomly assigned to either a twelve-session group logotherapy programme or a control group. Results showed that spiritually sensitive logotherapy significantly reduced depression, anxiety, and stress, and significantly more so than in the control group (e.g. interaction effect for BDI-II: F = 56.8, p < 0.001, with a large effect size).

Re-examining Gender Earning Differentials in Malaysian Manufacturing

The manufacturing sector is a major avenue for female employment in the urban labor market in Malaysia. Only two studies, both published more than two decades ago, have examined gender earning differentials in this sector. Since then, the percentage of women being educated has increased, along with their participation rate, and several laws protecting their rights have also been passed, making it timely to re-examine the earnings gap. We do this by drawing on more recent data from a larger representative survey of manufacturing employees. The Blinder-Oaxaca technique, utilized in the previous two studies, was used to estimate the existing earnings gap and to decompose it to differences attributable to endowments, coefficients (traditionally viewed as subsuming discrimination), and the interaction between the two. We found a smaller gap than previously reported, with better female endowments helping to narrow the gap, and unexplained differences in coefficients being responsible for the remaining gap. The interaction effect was not statistically significant. Contrary to the earlier studies, the differential treatment of women in the manufacturing sector, rather than endowment differences, is hampering the equalization of earnings. This calls for newer approaches to closing the earnings gap.
