Fulltext The role of parenting styles on effort perseverance: the mediating role of conscientiousness and mindfulness

Ghannad SZ, Chegeni SA, Mohammad G, Allipour S

Jurnal Psikologi Malaysia, 2018;32:73-83.

The present study investigates the role of parenting styles on effort perseverance with mediating roles of conscientiousness and mindfulness as moderators. For this purpose, 272 Iranian high school girl students were chosen by stratified random sampling. Data were analyzed by Path Analysis and Hierarchical Regression methods. The results showed that maternal control, parental control and maternal responsibility predict effort perseverance through conscientiousness; and paternal responsibility indicates positive and significant relationship with effort perseverance. Furthermore, findings showed that the relationship between conscientiousness and effort perseverance was moderated by mindfulness. Parenting style is an important factor in predicting effort perseverance through conscientiousness. In addition, being mindfulness has an effective role in relation to conscientiousness and effort perseverance.

Lameness continues to be a welfare and economic issue for dairy cows. However, the consequences of lameness seem to be better understood by veterinarians and related personnel in comparison to dairy farmers. Prompt detection and treatment of lame cows is essential in reducing its negative impact on milk processing systems. To that end, understanding farmers' perceptions regarding the significance of lameness to dairy cows is vital. One fundamental aspect is the underestimation of lameness prevalence by dairy farmers, which is as a result of different understanding of the problem. The same applies to their decision to treat lame cows and to adopt various detection and management practices. All of these shortcomings contribute to poor cattle welfare and economic losses in dairy production. This review summarizes the results of studies that have investigated dairy farmers' perceptions of lameness and the associated implications on the wellbeing and productivity of dairy cows. Factors associated with farmers' attitudes toward claw health and lameness management are also presented. Additionally, economic observations relating to lameness prevention, treatment and the adoption of lameness detection systems are also highlighted. To strengthen these points, interventional programmes requiring farmers' participation are discussed as a promising approach in answering some of these challenges. A review of the literature indicates both the opportunities and barriers inherent in the tackling the lameness issue from the farmers' perspectives. Such knowledge is crucial in identifying measures on how to motivate dairy farmers towards proper lameness management.

Performance comparison of serum and urine biomarkers from independent samples for ovarian cancer screening

Song HJ, Kim JD, Park CY, Kim YS, Jeong KS

Sains Malaysiana, 2015;44:1671-1676.

This study compares the diagnostic performance of urine and serum multiple biomarkers for early diagnosis of ovarian
cancer. The sample population includes 119 benign and 101 ovarian cancer patients. The marker combinations used
to compare performance include 16 markers whose concentration values were obtained using the Luminex assay. In
order to identify an optimal marker combination that could classify ovarian cancer and benign patients, the area under
the curve (AUC) is used to evaluate 2-, 3-, and 4-marker combinations and the classification is performed by using
logistic regression. In the case of urine samples, the best AUC values are 87.89% for the 2 protein markers combination,
90.22% for the 3 markers combination, and 92.43% for the 4 marker combination. In contrast, the best AUC values
for serum sample are 92.4% for the 2 marker combination, 93.63% for the 3 marker combination and 94.63% for the
4 marker combination. This study confirmed that combining multiple biomarkers could improve diagnostic accuracy.
Even though the urine sample shows relatively lower performance than serum, urine could be utilized more widely for
its simple usability.

Relative growth of Harpiosquilla raphidea (Fabricius, 1798) (Crustacea: Stomatopoda) male and female populations

Antony P, Rahman M, Rajkumar M, Kamaruzzaman Yunus, Ajmal Khan S

Sains Malaysiana, 2014;43:1305-1310.

Morphometric analysis was carried out to find out changes in the growth pattern of male and female stomatopod, Harpiosquilla raphidea. Six morphometric relationships were examined on 105 males and 105 females, ranging in size from 103 to 207 mm and from 104 to 222 mm in total length, respectively. In both the sexes, the relative growth of carapace length, propodus length of raptorial claw and total weight in relation to total length was found positively allometric. Telson width in both the sexes and abdomen width in males showed slightly negative allometry, while the abdomen width of females showed slightly positive allometry, indicating some variation in the growth between sexes which could be attributed to the energy requirement for maturation in females. The propodus of females was also found to be bigger than that of males. It is quite interesting as males only have larger chela in other crustaceans. It has a functional significance in that it is of immense help at the time of intense feeding during maturation of oocytes which requires higher energy.

Nurul Hidayah Che Mat, Md Atiqur Rahman Bhuiyan, Senan S, Ratnam W, Zahira Yaakob

Sains Malaysiana, 2015;44:1567-1572.

Phenotypic selection of individuals is the first step in a selective breeding program for elite hybrid seed production. In
this study, a total of 295 Jatropha curcas individuals raised from cuttings representing 21 accessions, collected from eight
different countries were evaluated for growth performance. The evaluation was done at the Biodiesel Research Station
of Universiti Kebangsaan Malaysia, Kuala Pilah from December 2012 to December 2013. Individual plants from each
accession were observed on several agronomic and yield related traits and all the data were recorded periodically.
Performance of each accession was analyzed using Statistical Analysis System (SAS) 9.4. Four traits which were plant
height (PH), number of flowers per inflorescence (NFI), number of female flowers per inflorescence (NFFPI) and hundred
seed weight (HSW) showed significant differences among the accessions after one year of planting. Maximum values for
each trait were 115.5 cm for PH, 6 for number of branches per plant (BPP), 9 for number of inflorescences per plant
(NIPP), 25 for number of fruits per plant (NFPP), 5 for number of fruits per inflorescence (NFPI), 191 for NFI, 10 for
NFFPI, 81.0 g for HSW and 70 for number of seeds per plant (NSPP). Accession number 1 from Thailand showed the best
performance for most traits. A highly significant and positive correlation was found between NFPP and NSPP. Based on
superior trait values for NIPP, NFPP, NFPI, NFI, NFFPI and HSW, five plants from accession UKMJC 01, 04, 05, 13 and 14
have been selected for generating elite intraspecific hybrids.

Introduction: Understanding the prevalence of secondhand smoke (SHS) exposure and the associated factors is beneficial for the formulation of effective measures to reduce exposure to SHS. The purpose of this study was to determine SHS exposure at home and workplace, and its associated factors among non-smoker Malaysian adults. Methods: Data were extracted from the Global Adult Tobacco Survey-Malaysia (GATS-M) that involved a representative sample of 5112 Malaysian adults. Logistic regression analyses were performed to examine the association between SHS exposure, sociodemographic factors, knowledge on the danger of SHS, and smoking restrictions at home and at work among non-smokers. Results: Among non-smoker Malaysians, age ≥15 years, 27.9% (equivalent to approximately 4.21 million non-smokers) and 33.9% (equivalent to approximately 1.37 million non-smokers) reported that they were exposed to SHS at home and the workplace, at least once a month, respectively. Women (AOR=2.12, 95% CI: 1.61.2.78), young individuals (AOR=3.06, 95% CI: 1.48.6.33), Malays (AOR=2.39, 95% CI: 1.56.3.64) or other Bumiputra ethnic groups (AOR=2.40, 95% CI: 1.39.4.19) and those who worked as other than government employees were more likely to report SHS exposure at home (non-government employee: AOR=1.88, 95% CI: 1.06.3.36). Respondents with a total smoking restriction at home did not report any SHS exposure at home. Similarly, those whose workplace had smoking restrictions were less likely to report SHS exposure at the work compared to their counterparts whose workplace had partial (AOR=3.08, 95% CI: 1.84.5.15) or no smoking restrictions (AOR=15.33, 95% CI: 6.75.34.86). Conclusions: A substantial proportion of Malaysian adults were exposed to SHS at home and at work. The findings emphasize the need for policies on smoking restrictions at work and the need to promote the adoption of a completely smoke-free home, among the Malaysian population.

A speech test that emphasizes on fricatives and affricates with high-frequency components is recommended for testing individuals with high-frequency hearing loss. Validation of the frequency-lowering feature in modern hearing aids are also important. There has been no recorded speech material in Malaysia that focuses on Mandarin fricatives and affricates. Therefore, the objective of this study was to develop a nonsense word test that contains Mandarin sibilant fricatives and affricates. A total of 180 vowel-consonant-vowel (vcv) nonsense syllables were recorded from a female and a male talker. These vcv syllables included six targeted Mandarin fricatives and affricates in three vowel contexts. Perceptual and acoustic analysis were conducted and selected vcv syllables were validated by 24 native Mandarin talkers with normal hearing through identification testing. Hundred and three syllables were rated as having a good or excellent sound quality and free from at least one of the idiosyncrasy elements. The average percentage of correct identification of vcv tokens for the female and male talkers were 85.38% and 82. 73%, respectively. Syllables that received the highest correct identification scores above the group mean were taken as the best exemplars. In total, 29 best exemplars were selected from 180 vcv syllables for the development of the Mandarin fricative-affricate nonsense word test. Future studies should include the development of performance-intensity function for individuals with normal hearing and a test manual so that the test can be used by non-native Mandarin clinicians.

MyJurnal

Enhancement of physical function had been shown in older adults who actively participate in physical activities, particularly in the form of aerobic training with addition of progressive resistance training (PRT). However, it is quite challenging and risky for most older adults to exercise in standing position without any support. Chair Based Exercise (CBE) is an alternative mode of exercise for older adult to facilitate exercise participation and increase safety. Its effect when combined with resistance training is unknown to date. Therefore, the aim of this study was to evaluate the outcome of CBE with PRT on physical performances among older adults. A total of 18 older adults (13 females (72%)) and 5 males (28%)), aged 60 to 83 years with mean age (SD) 72.67 (6.17) years completed the study. All subjects performed CBE with PRT intervention twice weekly for 8 weeks, with individually-tailored exercise progressions. Pre and post measurements of physical performance were performed using Six MinutesWalk Test (6MWT), Five Times Sit to Stand (FTSTS) and Hand Grip Strength (HGS) test. Significant improvement in 6MWT (p < .001), HGS Right hand (p = .043), HGS Left hand (p < .001), FTSTS (p < .001) was shown after the eight-week intervention. Adding PRT into seated exercises results in further improvement in physical performance of older adults. CBE-PRT may be recommended as an exercise routine for older adults living in the community.

Fulltext The academic consequences of problem behaviours in middle childhood and linkages between externalising and internalising difficulties

Kong K

Jurnal Psikologi Malaysia, 2017;31:84-95.

Numerous studies have documented relationships between problem behaviours and academic achievement measures. This study was initiated to address the relationship between parentreported problem behaviour symptoms (externalising and internalising) and standardised measures of academic achievement. The sample comprised of 3678 boys and 3846 girls in Ireland who were tracked over two time points. The first wave of data was collected when the children were 9 years old, followed by a second wave when they turned 13 years. An autoregressive model linking data at age 9 and age 13 was used to test the linkages between problems behaviours (externalising and internalising) and academic achievement over time, while simultaneously controlling for within-time association. Secondarily, the study also seeks to clarify the association between symptoms of externalising and internalising within the broader domain of problem behaviours itself. Results suggested that problems behaviours evident in middle childhood appeared to undermine academic competence by early adolescence. Likewise, early academic failures were associated with later problem behaviours. On the other hand, externalising and internalising difficulties showed reciprocal relationships over time. Implications of cascade effects for research and intervention are discussed

Assessment of GHG emission reduction potential from Source-separated Organic Waste (SOW) management: case study in a Higher Educational Institution in Malaysia

Chee GN, Sumiani Yusoff

Sains Malaysiana, 2015;44:187-192.

In Malaysia, the greenhouse gases (GHGs) emissions reduction via composting of source-separated organic waste (SOW) in municipal solid waste (MSW) has not been assessed. Assessment of GHG emissions reduction via composting of SOW is important as environmental impacts from waste management are waste-specific and local-specific. The study presents the case study for potential carbon reduction via composting of SOW in University of Malaya (UM). In this study, a series of calculations were used to evaluate the GHG emission of different SOW management scenarios. The calculations based on IPCC calculation methods (AM0025) include GHGs emissions from landfilling, fuel consumption in transportation and SOW composting activity. The methods were applied to assess the GHG emissions from five alternative SOW management scenarios in UM. From the baseline scenario (S0), a total of 1,636.18 tCO2e was generated. In conjunction with target of 22% recycling rate, as shown in S1, 14% reduction in potential GHG emission can be achieved. The carbon reduction can be further enhanced by increasing the SOW composting capacity. The net GHG emission for S1, S2, S3 and S4 were 1,399.52, 1,161.29, 857.70 and 1,060.48 tCO2e, respectively. In general, waste diversion for composting proved a significant net GHG emission reduction as shown in S3 (47%), S4 (35%) and S2 (29%). Despite the emission due to direct on-site activity, the significant reduction in methane generation at landfill has reduced the net GHG emission. The emission source of each scenario was studied and analysed.

Sains Malaysiana, 2016;45:745-751.

The aim of the present study was to estimate the epidemic situation of mites, in rabbit dermatologic disease in and around
Qena province, in the southern region of Egypt. Two hundred cases of dermatologic disease from the formentioned province
were investigated by conducting deep skin scraping between May 2011 and October 2012. The overall prevalence was
25%. Sarcoptic scabiei uniculi (22.5%) was the most frequent mite, followed by Notoedres cati cuniculi (2.5%). To the
best of our knowledge this is the first report of Notoedres cati cuniculi among studied rabbits in the study region. Study
on different breeds, English represents highest prevalence of mites 30%. Moreover, there was no significant difference
in the prevalence of mange mite infection between male and female rabbits (p > 0.05). Similarly, the prevalence was not
significant among the age groups and rabbit breeds (p > 0.05). In conclusion, the present prevalence of mange mites
was still high enough to cause significant economic losses in the study area. Therefore, strengthening the control effort
was suggested.

Fulltext Morphological descriptions and morphometric discriminant function analysis reveal an additional four groups of Scylla spp

Fazhan H, Waiho K, Quinitio E, Baylon JC, Fujaya Y, Rukminasari N, et al.

PMID: 31915566 DOI: 10.7717/peerj.8066

There are four species of mud crabs within the genus Scylla, and most of them live sympatrically in the equatorial region. Apart from a report in Japan about the finding of a natural Scylla hybrid more than a decade ago after the division of genus Scylla into four species by Keenan, Davie & Mann (1998), no subsequent sighting was found. Thus, this study investigates the possible natural occurrence of potential hybridization among Scylla species in the wild. A total of 76,211 individuals from mud crab landing sites around the Malacca Straits, South China Sea and Sulu Sea were screened. In addition to the four-purebred species, four groups (SH 1, n = 2, 627; SH 2, n = 136; SH 3, n = 1; SH 4, n = 2) with intermediate characteristics were found, mostly at Sulu Sea. Discriminant Function Analysis revealed that all Scylla species, including SH 1 - 4, are distinguishable via their morphometric ratios. The most powerful discriminant ratios for each character and the top five discriminant ratios of males and females were suggested. The carapace width of SH 1 males and females were significantly smaller than pure species. Based on the discriminant ratios and the description of morphological characters, we hypothesize that the additional four groups of Scylla with intermediate characteristics could be presumed hybrids. Future work at the molecular level is urgently needed to validate this postulate.

Akhtar M, Fatima T

J Pak Med Assoc, 2020 Jan;70(1):90-95.
PMID: 31954030 DOI: 10.5455/JPMA.8682

Objective: To study the phenomenon of cyberchondria and related worries about health among individuals without any diagnosed medical condition. .
METHODS: The survey-based, cross-sectional study was conducted from January to July 2018 in the twin cities of Rawalpindi and Islamabad, Pakistan, and comprised graduates of either gender aged at least 35 years with access to internet and means of use, and with no current diagnosed medical condition. The self-reporting Cyberchondria Severity Scale was used data-collection along with a demographic sheet. SPSS 21 was used for data analysis.
RESULTS: Of the 150 subjects, 90(60%) were men and 60(40%) were women. A total of 40(26.6%) subjects had low level of cyberchondria, while 35(23.3%) experienced a higher level of it. Mean scores of men on total CSS were slightly higher than those of women (p>0.05). Men also scored higher on compulsion, distress, excessiveness and reassurance subsclaes (p>0.05 each), whereas women scored slightly higherthan men on 'mistrust of medical profession' subscale (p>0.05). No significant gender differences werefound on cyberchondria and its subscales (p>0.05 each).
CONCLUSIONS: Doctors / health professionals may benefit from the findings by focussing on their patients who use internet as a major source of medical information.

One of the goals for primate feeding ecology is to understand the factors that affect inter- and intra-specific variations. Therefore, a detailed description of basic feeding ecology in as many populations as possible is necessary and warrants further understanding. The black-and-white colobus (Colobus guereza) or guereza is widely distributed in Africa and is one of the well-studied colobines in terms of their feeding; they demonstrate considerable variation in their diets in response to local conditions. We studied the diet of a group of guerezas in the Kalinzu Forest, Uganda, for over 30 consecutive months using behavioral observation (4308 h in total), phenology, and vegetation surveys. A total of 31 plant species were consumed by the study group. This study group was predominantly folivorous; the majority of their feeding time was involved in feeding on young leaves (87%). However, during certain times of the year, fruits and seeds accounted for 45% of monthly feeding time. Young leaves of Celtis durandii were by far the most important food, which constituted 58% of the total feeding records. There was a significant increase in the consumption of fruits and flowers once young leaf availability was low, but their consumption of fruits did not significantly increase even when fruit availability was high. Their monthly dietary diversity increased as the number of available plants with young leaves declined, suggesting that much of the dietary diversity in the study group may be attributable to the young leaf portion of their diet. Our findings may help contribute to a better understanding of the dietary adaptations and feeding ecology of guerezas in response to local environmental conditions.

The Breast Size Satisfaction Survey (BSSS): Breast size dissatisfaction and its antecedents and outcomes in women from 40 nations

Swami V, Tran US, Barron D, Afhami R, Aimé A, Almenara CA, et al.

Body Image, 2020 Mar;32:199-217.
PMID: 32032822 DOI: 10.1016/j.bodyim.2020.01.006

The Breast Size Satisfaction Survey (BSSS) was established to assess women's breast size dissatisfaction and breasted experiences from a cross-national perspective. A total of 18,541 women were recruited from 61 research sites across 40 nations and completed measures of current-ideal breast size discrepancy, as well as measures of theorised antecedents (personality, Western and local media exposure, and proxies of socioeconomic status) and outcomes (weight and appearance dissatisfaction, breast awareness, and psychological well-being). In the total dataset, 47.5 % of women wanted larger breasts than they currently had, 23.2 % wanted smaller breasts, and 29.3 % were satisfied with their current breast size. There were significant cross-national differences in mean ideal breast size and absolute breast size dissatisfaction, but effect sizes were small (η2 = .02-.03). The results of multilevel modelling showed that greater Neuroticism, lower Conscientiousness, lower Western media exposure, greater local media exposure, lower financial security, and younger age were associated with greater breast size dissatisfaction across nations. In addition, greater absolute breast size dissatisfaction was associated with greater weight and appearance dissatisfaction, poorer breast awareness, and poorer psychological well-being across nations. These results indicate that breast size dissatisfaction is a global public health concern linked to women's psychological and physical well-being.

PMID: 32140592 DOI: 10.1016/j.heliyon.2020.e03476

A growing number of Cambodian children without legal documentary evidence of date of birth are vulnerable to exploitation. This study aimed to evaluate the applicability of southern Chinese reference dataset for dental age estimation on Cambodian children and young adults of different socioeconomic status. Dental panoramic tomographs (DPT) of 371 Cambodian children and young adults belonging to lower and higher socioeconomic status (SES) groups were analyzed. All the left maxillary and mandibular permanent teeth including the third molars were scored based on Demirjian's classification of tooth development stages. Chronological age (CA) was calculated from the date of birth and date of exposure of radiograph. The mean age of attainment for each stage of development was obtained from the southern Chinese reference dataset. Dental age (DA) was calculated by averaging the mean age scores for all the teeth. Paired t-test and correlation analysis were conducted to measure associations between the chronological age and the dental age for males and females in the lower and higher socio-economic status groups. Underestimation of age was observed in both SES groups using the southern Chinese reference dataset. For the higher SES group, the difference between the chronological and dental age (CA-DA) was 0.26 years for females and 0.11 years for males. The difference was statistically significant only in females (p < 0.05). In the low SES group, the results showed a difference of 0.07 years in females and 0.01 years in males; the differences were not statistically significant in both sexes (p > 0.05). A strong correlation was observed between the CA and DA in both sex and SES groups ranging from 0.969 to 0.988 (p < 0.05). The southern Chinese dental reference dataset can be used to estimate the age of undocumented Cambodian male and female children and young adults of both higher and lower SES.

Fulltext Ultrasound-guided Percutaneous Lavage in the Treatment of Calcific Tendinopathy of Elbow Extensor Tendons: A Case Report

Abate M, Salini V, Schiavone C

Malays Orthop J, 2016 Jul;10(2):53-55.
PMID: 28435563 DOI: 10.5704/MOJ.1607.011

We report the efficacy of the ultrasound-guided percutaneous treatment in the management of elbow extensor tendons calcific tendinopathy. The ultrasound-guided percutaneous treatment is broadly used with positive results in patients suffering from rotator cuff calcific tendinopathy. However, this interventional method has been reported only in one patient in the medical literature. A 34 years-old female who complained pain, swelling and severe functional limitation of the right elbow was referred to our unit. Elbow radiographs and ultrasound examination showed a soft-fluid calcification above the origin of the extensor tendons. Ultrasound-guided percutaneous treatment was therefore performed. After one year, the patient reported no pain and regained complete range of elbow motion. This method, in well trained hands, is an alternative treatment in the management of the uncommon elbow calcific deposit.

The electronic song "Scary Monsters and Nice Sprites" reduces host attack and mating success in the dengue vector Aedes aegypti

Dieng H, The CC, Satho T, Miake F, Wydiamala E, Kassim NFA, et al.

Acta Trop, 2019 Jun;194:93-99.
PMID: 30922800 DOI: 10.1016/j.actatropica.2019.03.027

Sound and its reception are crucial for reproduction, survival, and population maintenance of many animals. In insects, low-frequency vibrations facilitate sexual interactions, whereas noise disrupts the perception of signals from conspecifics and hosts. Despite evidence that mosquitoes respond to sound frequencies beyond fundamental ranges, including songs, and that males and females need to struggle to harmonize their flight tones, the behavioral impacts of music as control targets remain unexplored. In this study, we examined the effects of electronic music (Scary Monsters and Nice Sprites by Skrillex) on foraging, host attack, and sexual activities of the dengue vector Aedes aegypti. Adults were presented with two sound environments (music-off or music-on). Discrepancies in visitation, blood feeding, and copulation patterns were compared between environments with and without music. Ae. aegypti females maintained in the music-off environment initiated host visits earlier than those in the music-on environment. They visited the host significantly less often in the music-on than the music-off condition. Females exposed to music attacked hosts much later than their non-exposed peers. The occurrence of blood feeding activity was lower when music was being played. Adults exposed to music copulated far less often than their counterparts kept in an environment where there was no music. In addition to providing insight into the auditory sensitivity of Ae. aegypti to sound, our results indicated the vulnerability of its key vectorial capacity traits to electronic music. The observation that such music can delay host attack, reduce blood feeding, and disrupt mating provides new avenues for the development of music-based personal protective and control measures against Aedes-borne diseases.
