Global Journal of Sociology: Current Issues A survey of lasting marriages among husbands and wives in Malaysia

Recent statistics have shown the increasing trend of divorce cases among Malay Muslims in Malaysia. Past research has focused on marriage satisfaction and the quality of the relationship in marriages. However, there is limited research on the factors that contribute significantly to a long-lasting marriage, particularly among the Malay Muslim community. This paper aims to share the initial findings to explore the strength of relationships in a lasting marriage among Muslim Malay couples in Malaysia. This paper adopts a qualitative approach. The study conducts an extensive literature review to find out some of the causes of divorce and factors that improve a long marriage. The findings indicate that three main considerations in the choice of a spouse are religion, responsible character good mannerisms and race. Age, looks and job are the least considered factors that account for the sustenance of marriage.
Shocks and angular momentum flips: a different path to feeding the nuclear regions of merging galaxies

We study the dynamics of galaxy mergers, with emphasis on the gas feeding of nuclear regions, using a suite of hydrodynamical simulations of galaxy encounters. The high spatial and temporal resolution of the simulations allows us to not only recover the standard picture of tidal-torque-induced inflows, but also to detail another, important feeding path produced by ram pressure. The induced shocks effectively decouple the dynamics of the gas from that of the stars, greatly enhancing the loss of gas angular momentum and leading to increased central inflows. The ram-pressure shocks also cause, in many cases, the entire galactic gas disc of the smaller galaxy to abruptly change its direction of rotation, causing a complete ‘flip’ and, several 108 yr later, a subsequent ‘counter-flip’. This phenomenon results in the existence of long-lived decoupled gas–stellar and stellar–stellar discs, which could hint at a new explanation for the origin of some of the observed kinematically decoupled cores/counter-rotating discs. Lastly, we speculate, in the case of non-coplanar mergers, on the possible existence of a new class of remnant systems similar to some of the observed X-shaped radio galaxies.
Deterministic processes drive national‐scale patterns in lake surface sediment bacteria and eukaryotic assemblage composition

Biological communities within lake surface sediments play a vital role in biogeochemical cycling and ecosystem services. Knowledge on abundance‐occupancy patterns and assembly processes across large spatial scales and over multiple environmental gradients is limited, yet essential to aid in protection and restoration. In the present study, surface sediment samples were collected from 296 lakes across a wide spatial scale and covering multiple interacting environmental gradients including size, depth, altitude, and trophic state. A suite of physicochemical parameters were used to characterize the environmental conditions and bacterial and eukaryotic assemblages were determined using 16S and 18S rRNA metabarcoding. The majority (~ 55%) of amplicon sequence variants were only found in a single lake with eukaryotes having a more restricted distribution than bacteria. Deterministic processes were inferred to be dominant for both bacteria (78%) and eukaryotes (51%), with variable selection being especially important for bacteria (49%). Variation partitioning indicated that land use in the catchment, which is strongly related to trophic state, was the most important environmental factor in explaining the assemblage composition. This nationwide study across broad gradients provides new insights into the ecology of bacteria and eukaryotes in lake surface sediments and a platform to better understand the effects of multiple environmental stressors on lake sediment assemblages.
Characteristics of the ocean simulations in the Max Planck Institute Ocean Model (MPIOM) the ocean component of the MPI‐Earth system model

MPI‐ESM is a new version of the global Earth system model developed at the Max Planck Institute for Meteorology. This paper describes the ocean state and circulation as well as basic aspects of variability in simulations contributing to the fifth phase of the Coupled Model Intercomparison Project (CMIP5). The performance of the ocean/sea‐ice model MPIOM, coupled to a new version of the atmosphere model ECHAM6 and modules for land surface and ocean biogeochemistry, is assessed for two model versions with different grid resolution in the ocean. The low‐resolution configuration has a nominal resolution of 1.5°, whereas the higher resolution version features a quasiuniform, eddy‐permitting global resolution of 0.4°. The paper focuses on important oceanic features, such as surface temperature and salinity, water mass distribution, large‐scale circulation, and heat and freshwater transports. In general, these integral quantities are simulated well in comparison with observational estimates, and improvements in comparison with the predecessor system are documented; for example, for tropical variability and sea ice representation. Introducing an eddy‐permitting grid configuration in the ocean leads to improvements, in particular, in the representation of interior water mass properties in the Atlantic and in the representation of important ocean currents, such as the Agulhas and Equatorial current systems. In general, however, there are more similarities than differences between the two grid configurations, and several shortcomings, known from earlier versions of the coupled model, prevail.
H_inf Performance to Stability and Stabilization for Singular Time Delay Systems

This paper is concerned with delay-dependent control of linear singular time delay systems. Based on linear matrix inequality (LMI) approach, we design a state feedback controller, which guarantees the resultant closed-loop system is regular, impulse free, and stable with performance constraint. The results are delay dependent. Numerical examples show that significant improvements are achieved over some existing methods.
Odor Pleasantness Modulates Functional Connectivity in the Olfactory Hedonic Processing Network

Olfactory hedonic evaluation is the primary dimension of olfactory perception and thus central to our sense of smell. It involves complex interactions between brain regions associated with sensory, affective and reward processing. Despite a recent increase in interest, several aspects of olfactory hedonic evaluation remain ambiguous: uncertainty surrounds the communication between, and interaction among, brain areas during hedonic evaluation of olfactory stimuli with different levels of pleasantness, as well as the corresponding supporting oscillatory mechanisms. In our study we investigated changes in functional interactions among brain areas in response to odor stimuli using electroencephalography (EEG). To this goal, functional connectivity networks were estimated based on phase synchronization between EEG signals using the weighted phase lag index (wPLI). Graph theoretic metrics were subsequently used to quantify the resulting changes in functional connectivity of relevant brain regions involved in olfactory hedonic evaluation. Our results indicate that odor stimuli of different hedonic values evoke significantly different interaction patterns among brain regions within the olfactory cortex, as well as in the anterior cingulate and orbitofrontal cortices. Furthermore, significant hemispheric laterality effects have been observed in the prefrontal and anterior cingulate cortices, specifically in the beta ((13–30) Hz) and gamma ((30–40) Hz) frequency bands.
The role of emotionally persuasive messages in the skin cancer prevention campaign

ABSTRACT Despite a multitude of social campaigns and widely publicized scientific evidence of how excessive, unprotected sun exposure damages the skin and is a key cause of the skin cancer, people continue to crowd the beaches, oftentimes without any sunscreen protection. Also numbers of those who use sunscreen on a daily basis remain low. In this study, we analyze how the attitudes toward tanning and behavior of sunscreen use change under the influence of persuasive messages. We compare the effectiveness of an emotionally neutral persuasive message to an emotionally negative persuasive message. We show that persuasive messages combining fear with other negative emotions are successful, however, those generating negative emotions are not significantly more effective than emotionally neutral messages. Furthermore, our results show that while persuasive messages can change the attitudes toward tanning, they do not directly lead to a behavioral change in terms of sunscreen use intentions. However, as we show, the tanning attitude mediates the relationship between persuasive message and the attitude toward sunscreen use and intentions to use it. The resulting change in the tanning attitude contributes to a change in the attitude toward use of sunscreen.
Alternation biases in corpora vs. picture description experiments: DO-biased and PD-biased verbs in the Dutch dative alternation

In semantic studies of argument structure alternations as well as in recent psycholinguistic research on syntactic priming, the concept of alternation bias, i.e. the lexical preferences of individual verbs for one of two (or more) alternating constructions, plays a crucial role. This paper offers a detailed comparison of the results from Colleman’s (2009) corpus-based investigation of the dative alternation in Dutch with the findings from a series of picture description experiments reported in Bernolet (2008). On the one hand, this comparison reveals a striking contrast between both datasets in terms of the overall proportions of double object (DO) versus prepositional dative (PD) instances. On the other hand, it will be shown that the alternation biases of individual dative verbs are actually quite consistent across both the corpus and the experimental data, provided these are measured in a way which evaluates the observed frequencies for individual verbs against the overall observed frequencies in the respective datasets.
Africa and Ethnic Politics

Abstract This article provides an overview of the theoretical and empirical contributions made by scholars of ethnic politics in Africa. I first discuss the definitions and measures of ethnic politics most commonly used. I then review the main explanations of the prevalence of ethnic politics. The following sections discuss the consequences of politicized ethnicity, variation in ethnic politics, and the relationship between ethnicity and other social identities, such as national identity. I conclude with some remarks about existing gaps and promising future avenues of research.
Electrostatic Wave Generation and Transverse Ion Acceleration by Alfvenic Wave Components of BBELF Turbulence

We present results here from 2.5-D particle-in-cell simulations showing that the electrostatic (ES) components of broadband extremely low frequency (BBELF) waves could possibly be generated by cross-field plasma instabilities driven by the relative drifts between the heavy and light ion species in the electromagnetic (EM) Alfvenic component of the BBELF waves in a multi-ion plasma. The ES components consist of ion cyclotron as well as lower hybrid modes. We also demonstrate that the ES wave generation is directly involved in the transverse acceleration of ions (TAI) as commonly measured with the BBELF wave events. The heating is affected by ion cyclotron resonance in the cyclotron modes and Landau resonance in the lower hybrid waves. In the simulation we drive the plasma by the transverse electric field, E(sub y), of the EM waves; the frequency of E(sub y), omega(sub d), is varied from a frequency below the heavy ion cyclotron frequency, OMEGA(sub h), to below the light ion cyclotron frequency, OMEGA(sub i). We have also performed simulations for E(sub y) having a continuous spectrum given by a power law, namely, |Ey| approx. omega(sub d) (exp -alpha), where the exponent alpha = _, 1, and 2 in three different simulations. The driving electric field generates polarization and ExB drifts of the ions and electrons. When the interspecies relative drifts are sufficiently large, they drive electrostatic waves, which cause perpendicular heating of both light and heavy ions. The transverse ion heating found here is discussed in relation to observations from Cluster, FAST and Freja.
Caregiving for People With Dementia or Cognitive Impairment During the COVID-19 Pandemic: A Review

The COVID-19 pandemic has been a major source of stress for informal caregivers for people with dementia. Studies show the unique challenges caregivers face, such as social isolation, extended work hours, and adherence to public health guidelines. We conducted a narrative review of factors impacting well-being of informal caregivers of older adults with dementia during the COVID-19 pandemic. Sixty-four papers were identified as published between June 2020 and December 2021. All studies were conducted in the U.S. or other Western countries and were cross-sectional and conducted prior to COVID-19 vaccines. Articles highlighted increasing burdens such as financial and physical stress, as well as worsened psychological well-being from anxiety and depression. Protective factors such as social support and telehealth interventions also emerged. Limitations include lack of longitudinal information to identify broader themes on caregiving during the pandemic. Studies not only identified new, pandemic-related risk factors, but also a heightened effect of pre-existing risk factors (e.g., income, living situation) on caregiver burden.
Phenotypes of Floral Nectaries in Developmental Mutants of Legumes and What They May Tell about Genetic Control of Nectary Formation

Simple Summary The third largest angiosperm family, Leguminosae, is remarkable with the outstanding diversity of its flowers, usually monosymmetric and adapted to different pollination strategies. A key attractant of leguminous flowers is nectar. Compared with Arabidopsis (Brassicaceae), very little is known about regulation of floral nectaries development in legumes. This work aimed to investigate details of these nectaries’ morphology in flowers of mutants of different legume species. It was found that the changes in identity of petals and stamens usually do not affect a proper structure and position of nectaries in leguminous flowers, thus suggesting a high stability of attracting structures versus the pronounced plasticity of perianth and stamens. Some of genes involved in regulation of nectary development in Arabidopsis seem to have the same functions in legumes. The principal difference between Arabidopsis and legumes is connected with a flower monosymmetry in most representatives of the latter taxon, which is also reflected in structure of their floral nectaries. Abstract The vast majority of angiosperms attracts animal pollinators with the nectar secreted through specialized floral nectaries (FNs). Although there is evidence that principal patterns of regulation of FN development are conserved in large angiosperm clades, these structures are very diverse considering their morphology and position within a flower. Most data on genetic control of FN formation were obtained in surveys of a model plant species, Arabidopsis thaliana (Brassicaceae). There are almost no data on genetic factors affecting FN development in Leguminosae, the plant family of a high agricultural value and possessing outstandingly diverse flowers. In this work, the morphology of FNs was examined in a set of leguminous species, both wild-type and developmental mutants, by the means of a scanning electron microscopy. Unlike Brassicaceae, FNs in legumes are localized between stamens and a carpel instead of being associated with a certain floral organ. FNs were found stable in most cases of mutants when perianth and/or androecium morphology was affected. However, regulation of FN development by BLADE-ON-PETIOLE-like genes seems to be a shared feature between legumes (at least Pisum) and Arabidopsis. In some legumes, the adaxial developmental program (most probably CYCLOIDEA-mediated) suppresses the FN development. The obtained results neither confirm the role of orthologues of UNUSUAL FLORAL ORGANS and LEAFY in FN development in legumes nor reject it, as two studied pea mutants were homozygous at the weakest alleles of the corresponding loci and possessed FNs similar to those of wild-type.
The Impacts of Stress and Resilience on Intentions to Leave the Nursing Profession among Newly Graduated Nurses

: Registered nurses are a professional group that suffer from high levels of stress-related conditions. Thus, this study aimed to identify the impacts of stress and resilience on intentions to leave the nursing profession among newly graduated nurses (n = 165). A descriptive cross-sectional design and purposive sampling were used. Most of the respondents showed a moderate level of resilience and a high level of stress. Of the participants, 12.7% reported an intention to leave the nursing profession. A strong correlation was found between levels of resilience and stress among newly graduated nurses. Effective stress management and interventions to improve resilience in newly graduated nurses are highly recommended.
LMC K‐Band Distance from Precision Measurements—and Implications for fhe Cepheid PL Relation

High‐precision (σ<0.01) new K‐band observations of a sample of the brightest and nearest red clump stars in the solar neighborhood are used to determine a distance modulus for the LMC. The resulting value of 18.47±0.03 implies a very small correction to the Cepheid PL relation due to the difference in metallicity between LMC Cepheids and Cepheids in the solar neighborhood.
Linear perturbation analysis of hairy black holes in shift-symmetric Horndeski theories: Odd-parity perturbations

We analyze the mode stability of odd-parity perturbations of black holes with linearly time-dependent scalar hair in shift-symmetric Horndeski theories. We show that a large class of black hole solutions in these theories suffer from ghost or gradient instability, while there are some classes of solutions that are stable under linear odd-parity perturbations in the context of mode analysis.
Three carbon-enhanced metal-poor dwarf stars from the SDSS - Chemical abundances from CO5BOLD 3D hydrodynamical model atmospheres

Context. The origin of carbon-enhanced metal-poor stars enriched with both s and r elements is highly debated. Detailed abundances of these types of stars are crucial to understand the nature o f their progenitors. Aims. The aim of this investigation is to study in detail the abunda nces of SDSS J1349-0229, SDSS J0912+0216 and SDSS J1036+1212, three dwarf CEMP stars, selected from the Sloan Digital Sky Survey. Methods. Using high resolution VLT/UVES spectra (R�30 000) we determine abundances for Li, C, N, O, Na, Mg, Al, Ca, Sc, Ti, Cr, Mn, Fe, Co, Ni and 21 neutron-capture elements. We made use of CO 5 BOLD 3D hydrodynamical model atmospheres in the analysis of the carbon, nitrogen and oxygen abundances. NLTE corrections for Ci and Oi lines were computed using the Kiel code. Results. We classify SDSS J1349-0229 and SDSS J0912+0216 as CEMP-r+s stars. SDSS J1036+1212 belongs to the class CEMPno/s, with enhanced Ba, but deficient Sr, of which it is the third m ember discovered to date. Radial-velocity variations have been observed in SDSS J1349-0229, providing evidence that it is a member of a binary system. Conclusions. The chemical composition of the three stars is generally compatible with mass transfer from an AGB companion. However, many details remain diffi cult to explain. Most notably of those are the abundance of Li at the level of the Spite plateau in SDSS J1036+1212 and the large over-abundance of the pure r-process element Eu in all three stars.
Etiological spectrum of cardioembolic strokes in a tertiary care hospital of India: Analysis of one year data

Background: Traditionally rheumatic heart disease with mitral stenosis and atrial fibrillation has been the common mechanism of cardioembolic strokes in India. However, with the increase in life span and higher detection and development of cardiac diseases, the frequency and etiologic spectrum of cardioembolic stroke in an Indian hospital may be changing. Methods: The case records of patients admitted in the year 2020 were analyzed for the presence of risk factors and identified stroke mechanisms. Results: Among 538 patients of ischemic strokes, cardioembolic source was identified in 156 (29.8%) patients. Five major cardiac sources of embolism were identified: Coronary artery disease (with acute or remote myocardial infarction) 56/156 (35.89%), non valvular atrial fibrillation, 34/156(21.79%), post cardiac intervention 28/156 (17.94%), left atrial cardiomyopathy 20/156 (12.8%), and rheumatic heart disease 13/156 (8.3%). Conclusion: Coronary artery disease, non valvular atrial fibrillation, post intervention stroke and left atrial cardiomyopathy are emerging as common causes of cardioembolic strokes. Rheumatic heart disease continues to be an important but less frequent cause of cardioembolic strokes.
Scaffolding Junior Middle School Students’ Engagement in Online Project-based Learning During the COVID-19 Pandemic: A Case Study from East China

During the COVID-19 pandemic, online learning has experienced increasing utilization and poses new challenges for schoolteachers to engage students. Project-based Learning (PBL) is widely acknowledged as an effective pedagogy for motivating and involving students. However, few studies have examined scaffolds that facilitate student engagement in the context of distance PBL. This mixed-method study was conducted with grade 7 teachers and students in a junior middle school in East China from March 2020 to April 2020. Qualitative analysis was employed in interviews with 2 teachers and 21 students. Quantitative analysis was used to visualize the self-reflection reports of 39 students. The findings suggest that the scaffolds of teacher direction, technology support, peer collaboration, and parental assistance play a significant role. In addition, specific scaffolding within the above categories was revealed. The results highlight the problem-oriented, methodological, and synthesized application of various scaffold(ing)s in engaging students and emphasize that scaffolding students emotionally is the core issue to support engagement for remote learning.
