THE ACTIVITY OF THE MIRROR SYSTEM OF THE BRAIN DURING THE PERCEPTION OF SPEECH AND ITS RELATIONSHIP WITH THE LEVEL OF INTELLIGENCE AND EMPATHY
Authors: Portugalskaia A. A. , Levenchik G. Ja. , Pavlenko V. B.
Published: July 2021

Previously, researchers hypothesized that the emergence of a system of mirror neurons (MNS) in the process of evolution could be a key mechanism that ensured the appearance of speech in humans. The aim of this work was to establish a relationship between the activity of the MNS in the perception of speech messages, indicators of intelligence and empathy. 25 healthy men and women (18–35 years old) were test subjects. We found that when observing hand movements with a computer mouse on a monitor screen and performing such movements independently, the power of EEG mu- and tau rhythms in the central and temporal cortical regions decreased in subjects. Based on this, we consider it probable that a certain contribution to the dynamics of neocortex activity in this situation is made by the activation of neurons in the MNS.
Upon presentation of speech utterances to the research participants, the EEG amplitude changed, including in the range of the alpha rhythm. The most pronounced EEG changes developed 0.3–0.5 s after the end of the keywords. The processing of information during the perception of the phrase “I raise my hands and raise my head” in most of the subjects was reflected in the desynchronization of the indicated rhythm. The perception of the absurd phrase «I run around my hands and run around my head» was often accompanied by an increase in EEG oscillations in the range of the alpha rhythm. The perception of such a phrase, including the awareness of its contradiction to common sense, apparently caused stress in memory processes with an attempt to actively inhibit irrelevant information. These processes probably led to an increase in the amplitude of mu and tau rhythms in the central and temporal regions of the neocortex.
The subjects with the highest IQs showed the greatest activation of the mu-rhythm when perceiving the correct phrase. When an absurd phrase was perceived, the greatest desynchronization in the central regions of the neocortex developed in subjects with high indices of various dimensions of empathy. Probably people with a high level of empathy, i.e. with a good development of emotional intelligence, they more easily and quickly realized the absurdity of the specified phrase. We consider the obtained results as evidence of the participation of MNS in the perception and awareness of speech messages describing a person’s physical actions.

Published: July 2021

The paper presents the study on the static mechanical properties of PLA (Polylactic Acid) produced with entry-level additive technologies using three printing directions. During the experimental work were tested a total of 15 �dog bone� ASTM D638-14 standard specimens made from additively manufactured polymer (PLA) through FDM (Fused Deposition Modelling) technique, where the material and rectilinear pattern infill geometry and infill percentage of 100% were constant and the printing orientation was varied. Usually technical data sheets that are delivered by filament materials producers include the most satisfactory data which are valid for only one specific printing direction. The printing direction is deliberately selected, in such way that the best material characteristics are achieved. In addition to this matter, as the additive manufacturing market grew significantly in the past couple of years, the filament production market showed a consequential growth. The aftermath of this expansion had a direct impact towards the quality and costs of the filaments used for 3D printing, in order to satisfy both the low-end and high-end users. Therefore, in this frame, the present research provides entry-level additively manufactured PLA performances showing significant changes depending on the different printing directions and determine the build orientation influence on the mechanical properties, in the aim of providing aid for both mechanical designer and product manufacturer at the stage of the printed product mechanical properties.
Artificial and Natural Aging of Polypropylene Used in Passenger Vehicle Bumpers
Authors: Zhang Hongshen , Zheng Hongfei
Published: July 2021

Polypropylene (PP) has a wide range of applications in the automobile bumpers due to its many excellent properties. Mechanical properties of PP for automobile bumpers are investigated through an artificial accelerated aging test. The aging rules after different years of normal use and the artificial accelerated aging test are analyzed. The correlation between natural and artificially accelerated aging is also explored. It provides a reference for the study of the aging properties of polymers for automotive applications. Results show that the UV aging test can effectively simulate changes in tensile and bending strengths after natural aging and can be used to evaluate the weathering resistance of PP materials used in automotive bumpers. The tensile and bending strengths of these materials remain good during aging, and elongation is sensitive to aging. The short-term artificial accelerated aging test does not exert a significant influence on the impact strength of materials, and artificial accelerated aging does not completely reproduce the aging process of the material.
Impact of Covid-19 on the dynamics of MTPL insurance premiums and claims paid in Latvia
Authors: Spilbergs Aivars , Fomins Andris , Krastins Maris
Published: July 2021

COVID-19 has devastated societies and economies around the world, leaving no sector untouched. The unprecedented crisis caused by Covid-19 led to unexpected changes in public behaviour: the restrictions imposed, especially during the pandemic outbreaks in March-April and November-December 2020, left a significant impact on traffic volumes. By the spring of 2020, more than half of the world’s population had been isolated with tough containment measures. Opportunities to work from home reduced the need to use private cars and, consequently, the demand for motor third party liability (MTPL) insurance. In order to understand the significance of the impact of the pandemic on MTPL insurance premiums and claims, the authors studied the impact of macroeconomic factors on the insurance market in Latvia in the period from 2005-2020. Using regression analysis methods, the evidence was obtained that changes in the macroeconomic situation significantly affect one of the main non-life insurance segments MTPL insurance. A set of indicators, that most significantly affect revenues and expenses in this business segment of insurance companies, was determined. The findings provide useful recommendations for insurance companies to reduce business risks and promote sustainable development. The results of the study are important for insurance-related econometric analysis, investment decisions, forecasting, and policy development.

Published: July 2021

The paper analyzes and marks the advantages and shortcomings of up-to-date methods of wastewater cleaning from oil products. Combined usage of distillation, electro-coagulating methods enabling to water clean to the maximum admissible li-mits is justified. The modified technological scheme of wastewater cleaning from petrochemicals is proposed and the data before and after wastewater cleaning presented as well. The combination methods of distillation, electro-coagulation and adsorption in the technological scheme increases the cleaning efficiency of the wastewater heavily emulsified with oil products. In distillation phase, 10-15 % of petrochemicals is removed from the wastewater from overall volume of feed water. Afterwards, the cleaning of emulsified and suspended petrochemicals rises up to 80-85 % of total feed wastewater. Finally, the emulsified petrochemicals from the wastewater may be removed for 99 % via adsorption method.

Published: July 2021

The development of oil-gas sector in Azerbaijan since the second half of the XX century was achieved mainly due to the exploitation of offshore fields. However, as a result of harsh hydro-meteorological conditions in the Caspian Sea, the exploration, as well as the development of offshore oil-gas deposits was not so easy. Exactly in such conditions due to the efforts of the scientists and experienced engineers and technicians specialized in this sphere, the hard exploration problem was solved both from geological and technical points of view. However, even today there are some technological and geological-technical issues during the operation of offshore oil-gas fields or in whole development of the resources. From this point of view Bahar field as the all fields being in long-term operation still have a large capacity of unused residual reserves of great importance. Therefore, accurate and detailed study of complicated oil recovery processes is a significant and current task. Thus, for the analysis of oil recovery processes it is necessary to select the optimum and economically feasible methods and practical to involve into the investigation dynamic model of “Stewhart control charts” for its solution.

Authors: Ali Shaista , Waqar Muhammad , Anwar Musarrat , Zahid Muhammad , Sattar Abdul , Arif Muhammad
Published: July 2021

OBJECTIVES:

To examine the psychological issues following acquired limb amputation and examine the significance of positive self-esteem in the psychological adjustment of amputation.

METHODOLOGY:

This case study was conducted in the surgical and orthopedic units of different government and private hospitals of Peshawar district. The study includes a sample of 100 acquired limb amputees,both adult males and females admitted in different hospitals of Peshawar. Patients with congenital limb loss or with preexisting psychological issues were excluded from the study. Psychological adjustment scale developed by Sabir (1999) and Self-Esteem scale developed by Rifai’s (1999) was used to determine the amputee’s level of psychological adjustment and self-esteem.

RESULTS:

Results revealed that amputation leads to number of psychological issues. It was found that males had lowered self-esteem and severe adjustment issues then females while young amputees exhibit greater signs of maladjustment as compared to older amputees. Regression analysis for selfesteem predicting psychological adjustment also displayed pronounced differences in the level of psychological adjustment due changing level of self-esteem. The model suggested a strong positive relation between self-esteem and psychological adjustment (r=0.880, B=0.867, t=18.37, p<.001) and 77.5% of the variance in the dependent variable (psychological adjustment) was caused by predictor variable i.e. self-esteem (R2=0.775, F (98)=337.6, p<.001).

CONCLUSION:

Amputation badly disturbs the psychological state of an amputee and an amputee’s self-esteem is an important coping tool and has a direct relation with better psychological adjustment to limb loss.
A STUDY OF EMOTIONAL INTELLIGENCE COMPETENCIES POSSESSED BY THE YOUTH
Authors: Mehta Mona , Dasgupta Rakhi , Modi Rutu
Published: July 2021

Emotional Intelligence Competencies amongst undergraduate university youth at a Higher Education Institution is one of the areas less ventured upon. Gardner (1983; 1991) reported that business-related graduate programmes focused primarily on indicators of individual competence such as logical and linguistic intelligence, with less attention being given to spatial, interpersonal and naturalist forms of intelligence. Later research reported increased calls from industry to make curricula more relevant to `today's global workplace' through improved instruction in communication, leadership, as well as intrapersonal and interpersonal skills (Cherniss 1999; Doria, Rozanski and Cohen, 2003; Jaeger 2003; Myers and Tucker 2005). Lately, Daniel Goleman's research on emotional intelligence as a predictor of work performance has emerged (Goleman 1998, 2000; Weisinger, 1998) and continues to be highly influential. The traditional approach by educationists, however, has been to focus on logical and linguistic intelligence. This view have been challenged by many studies recently where researchers are beginning to argue that interpersonal and intrapersonal competencies and Emotional Intelligence (EQ) may be more important for success. Educational institutions have traditionally focussed primarily on logical and linguistic intelligence, with less attention given to other types of intelligence. Yet many researchers are beginning to argue that intrapersonal and interpersonal competencies, or emotional intelligence, may be more important for success in life than logical or linguistic intelligence (Tucker, Sojka, Barone & McCarthy, 2000). Though the concept of emotional intelligence was first introduced in organizations, its relevance made the concept an inevitable concept of consideration in the educational sector too. Developing emotional intelligence skills amongst youth is very important because it can positively affect academic achievement not only during the session they are taught, but in subsequent years as well (Elias, Brune, Butler, Blum & Schumler, 1997). According to Caruso, Mayer and Salovey (2002), emotional intelligence skills and knowledge can be developed and learned and it matters most in times of change. Emotional intelligence is an ability to recognize one„s own feeling and those of others, for motivating self as well as one„s relationship with others. Studies (e.g. Ediger, 1997; Parker, Summerfeldt, Hogan & Majeski 2004)) have shown that the acquisition of emotional intelligence skills can significantly contribute to positive thinking in students and increase their ability to concentrate for a long time. The present research was thereby undertaken with the main aim of investigating the emotional intelligence competencies by the youth. Descriptive research design was taken up with questionnaire as a tool for the present
CENTRE AND THE MARGIN: INVESTIGATING THE POLITICS OF POWER IN LITTLE MAGAZINES OF THE 20TH CENTURY AMERICA
Authors: Surve Anshu , Basu Anwesha
Published: July 2021

During the 1920s, popularly known as the period of Harlem Renaissance, there was a rift in the society which impacted the entire social fabric poignantly the sufferings of the AfroAmericans in terms of racism, lynching, segregation problematizing the power structures and the societal ideology. Power, from an ideological point of view, can be described as an instrument of controlling the society, influencing people’s lives in myriad ways and achieving the intended targets as set by the centre. Power and politics can be viewed conjointly when we critically explore the Little Magazines brought out by the ones in the centre of the power structure and the other- in the periphery. Little Magazines, avant-garde and non-commercial in nature, served as cultural intermediaries, a medium of expression and a literary space mediating between the political, social and literary dimensions. The publication of the Little Magazines periodically by the people in power in the 20th century America, that is, the Whites reflected their domination in the printing industry; Little Magazines published by the Afro-Americans were mostly short-lived for paucity of support, funding and response. These little magazines brought to the surface issues like marginalization, subjugation, alienation, exploitation issues while, those published by the power centre celebrated the literary and artistic writings of the individuals and focused on creating “an alternative form of cultural capital in relation to mainstream magazines”, also aiming at expanding nationally and internationally. The paper attempts to closely look at the theorists Gayatri Chakraborty Spivak, Homi Bhabha, Judith Butler associated with the concept of class and race. This paper addresses the impact of the dynamics of power and its operation on the Afro-Americans in relation to identity and its representation.

Measurements of Coronal Magnetic Field Strengths in Solar Active Region Loops
Authors: Brooks David H. , Warren Harry P. , Landi Enrico
Published: July 2021

The characteristic electron densities, temperatures, and thermal distributions of 1 MK active region loops are now fairly well established, but their coronal magnetic field strengths remain undetermined. Here we present measurements from a sample of coronal loops observed by the Extreme-ultraviolet Imaging Spectrometer on Hinode. We use a recently developed diagnostic technique that involves atomic radiation modeling of the contribution of a magnetically induced transition to the Fe x 257.262 Å spectral line intensity. We find coronal magnetic field strengths in the range of 60–150 G. We discuss some aspects of these new results in the context of previous measurements using different spectropolarimetric techniques, and their influence on the derived Alfvén speeds and plasma β in coronal loops.

Published: July 2021

Individuals of mussels were collected in ponds from a commercial shrimp farm in the Unare region, Anzoátegui State, Venezuela. Identification was carried out using dichotomous keys and corroborated via analysis of similarities between the sequences of partial mitochondrial DNA of the cytochrome oxidase gene and Mytella strigata (Hanley, 1843) reported in GenBank with 99-100% similarity. Morphological analyses further supported the identification of the specimen. The first report of M. strigata in the Venezuelan Caribbean coast suggests that it could be a transplanted species. Possible negative effects of M. strigata on commercial shrimp production systems are discussed.

Among Bagre genera, there is a high variation in the estimation of age, a concern due to overexploitation risk in fisheries because of age underestimation. Bagre panamensis is an important fishery resource of the Mexican Pacific and the Gulf of California. Its age is known from otoliths, but its accuracy needs to be confirmed, and the periodicity of the otoliths record validated. The external morphology, some microstructure attributes, and age record of B. panamensis' otoliths were described from 371 specimens collected southeast of the Gulf of California. The lapilli otoliths were larger than the sagittae and asterisci otoliths. The lapilli otoliths present aragonite crystals with a prismatic shape, and their growth is radial, from the core to the otolith edge. The lapilli otoliths form an annual growth ring, defined by the slowdown in the growth that occurs during April to July, during the breeding season. The ages of the individuals ranged from 1 to 15 years, and the applied method is considered adequate and accurate for its estimation (otolith cross-sectioning and red-neutral staining).

Among the predatory ladybird beetles (Coccinellidae: Coleoptera), members of the Coccinellini, predators of aphids and psyllids, stand out. Although the beneficial status of these beetles has been acknowledged by biological control researchers, there are no keys or detailed studies on the immature stages of South American Coccinellidae, especially Coccinellini. We provide descriptions and illustrations of the immatures and adults of major predatory Coccinellini species in southern Brazil along with an identification key for fourth instar larvae and pupae. The following species are included:Cycloneda sanguinea(Linnaeus, 1763),Eriopis connexa(Germar, 1824),Harmonia axyridis(Pallas, 1773),Hippodamia convergensGuérin-Méneville, 1842 andOlla v-nigrum(Mulsant, 1866). The morphological study, which included the use of scanning electron microscopy, revealed new characters such as the type of tarsal claws, spiracles, chalazae, parascoli and strumae. The identification key provided here may be useful in biological control programs.

Published: July 2021

Purpose:

To evaluate risk factors and outcomes of preferred practice for infants with aggressive posterior retinopathy of prematurity (APROP) at a tertiary eye center in India.

Methods:

This was an observational study of infants with APROP where patients were divided into three groups after 2 weeks of initial treatment depending on the treatment received: anti-VEGF only, laser only, and combination of anti-VEGF injection followed by laser within 2 weeks of anti-VEGF injection (combined group). All infants were evaluated for risk factors and followed up at 1, 2, 4, 8, and 12 weeks to determine treatment outcomes in terms of regression, vascular re-growth, progression, and recurrence of the disease.

Results:

Sixty eyes of 31 infants were included in the study, with 26 eyes in the anti-VEGF only group, 19 eyes in the laser-only group, and 15 eyes in the combined group. Infants in the combined group presented late with lower birth weight (BW), smaller gestational age (GA), and a history of longer duration of ventilatory support. After 3 months of follow-up, regression occurred in 73.08% in the anti-VEGF only group, 89.5% in the laser-only group, and 86.66% in the combined group (
P
= .07). Zone of vascularization was greater in the anti-VEGF only group and the combined group compared to the laser-only group. Disease recurrence was seen in 27% in the anti-VEGF group, none in the laser-only group, and 13.33% in the combined group (
P
< .001). However, progression to stage 4 ROP requiring surgery was noted in 2 eyes in the laser-only group.

Conclusions:

Infants with APROP who have a lower GA or BW or require longer ventilatory support are possibly a subset best suited for planned combination therapy. A combination of anti-VEGF therapy followed by laser treatment within 2 weeks allows for early regression, a stable course, lower recurrence, and a larger area of retinal vascularization.

Comparison of Two Photoscreeners in a Population of Syrian Refugee Children
Authors: Gorham John P. , Behshad Soroosh , Weil Natalie C.
Published: July 2021

Purpose:

To evaluate children in the Za'atari refugee camp in Jordan to better understand the prevalence of ocular pathology and to compare two photoscreening devices to evaluate their utility.

Methods:

Families at the Syrian American Medical Society Clinic were offered vision screening for children aged 1 to 18 years. Participants were offered visual acuity measurement and photoscreening with two devices approved for use in the United States. If visual acuity in either eye was worse than 20/40 or either photoscreening device indicated possible pathology, a complete eye examination was performed with cycloplegic refraction and dilated examination.

Results:

Ninety-one participants completed the screening protocol. The average age of participants who completed the study was 7.8 years (range: 1 to 16 years). Twenty-eight participants (30.8%) failed at least one screening component. In this population, the following pathology was identified: astigmatism (12.1%), esotropia (9.9%), amblyopia (9.9%), hyperopia (7.7%), exotropia (3.3%), and myopia (1.1%). The Plusoptix vision screener (Plusoptix) had a sensitivity of 100% for the identification of amblyopia and 85% specificity. The GoCheck Kids application (Gobiquity) had a sensitivity of 66.67% for the identification of amblyopia and 94% specificity. The positive predictive value for the Plusoptix vision screener and the GoCheck Kids application for the detection of amblyopia risk factors was 77% for both.

Conclusions:

The high rate of ophthalmic pathology identified in this study reinforces the urgent need for proper vision screening and intervention in this population.

Sutureless Scleral-Fixated Intraocular Lens Implantation in the Treatment of Congenital Lens Subluxation Related to Marfan Syndrome
Authors: Bulut Muhammed Nurullah , Göktaş Eren , Karadağ Erdi , Bulut Kezban , Oral Ayşe Yeşim , Şimşek Şaban
Published: July 2021

Purpose:

To evaluate the efficacy and safety of bimanual capsulorhexis combined with sutureless scleral-fixated intraocular lens (IOL) implantation in children diagnosed as having Marfan syndrome.

Methods:

The study included 14 eyes with subluxated lenses of 7 children who were diagnosed as having Marfan syndrome and underwent bimanual capsulorhexis combined with sutureless scleral-fixated IOL implantation by the same surgeon between 2015 and 2019 at the University of Health Sciences, Kartal Dr. Lütfi Kirdar City Hospital's Eye Department.

Results:

The mean preoperative and postoperative uncorrected visual acuity was 1.47 ± 0.41 and 0.42 ± 0.15 logarithm of the minimum angle of resolution (logMAR), respectively (
P
= .001). The preoperative best corrected visual acuity (BCVA) ranged from 1.30 to 0.40 logMAR with a mean value of 0.81 ± 0.30 logMAR. Postoperatively, all patients had an increase in the BCVA with a mean value of 0.20 ± 0.11 logMAR, which was statistically significant (
P
= .001). The mean preoperative and postoperative spherical equivalent was −9.69 ± 4.59 and −0.27 ± 1.21 diopters, respectively.

Conclusions:

Despite the small number of patients in this study, good visual results and a low complication rate were obtained in patients with ectopic lens. The long-term IOL status in patients who have undergone sutureless scleral-fixated IOL implantation will make it possible to better evaluate the safety and applicability of the technique.

Associations Between Adverse Childhood Experiences and Substance Use in Nursing Students
Authors: Kameg Brayden , Mitchell Ann
Published: July 2021

Adverse childhood experiences (ACEs) are a public health problem, and exposure to ACEs can lead to negative health consequences, including substance use. Little is known about ACEs and substance use in the nursing student population. The purpose of the current study was to describe the types of ACEs encountered by nursing students and the rate at which they occur; and examine associations between individual ACEs and alcohol and drug use. This study uses a cross-sectional, descriptive design. Measurements were used to assess and quantify ACEs and alcohol and drug use. There were small to medium associations between alcohol use and ACE items, and more modest associations found between drug use and ACE items (
p
< 0.001). Findings highlight the need for a trauma-informed approach to nursing education. [

Wavefronts for degenerate diffusion-convection reaction equations with sign-changing diffusivity
Authors: Berti Diego , Corli Andrea , Malaguti Luisa
Published: July 2021

We consider in this paper a diffusion-convection reaction equation in one space dimension. The main assumptions are about the reaction term, which is monostable, and the diffusivity, which changes sign once or even more than once; then, we deal with a forward-backward parabolic equation. Our main results concern the existence of globally defined traveling waves, which connect two equilibria and cross both regions where the diffusivity is positive and regions where it is negative. We also investigate the monotony of the profiles and show the appearance of sharp behaviors at the points where the diffusivity degenerates. In particular, if such points are interior points, then the sharp behaviors are new and unusual.
Collection decisions and coordination in a closed-loop supply chain under recovery price and service competition
Authors: Feng Dingzhong , Zhang Xiaofeng , Zhang Ye
Published: July 2021

With the increasing growth of consumers' request for recovery channels, in addition to collecting price, the collecting service has gradually become a competitive point for collectors to collect used products. Focusing on a closed-loop supply chain (CLSC) with recovery competition (on collecting price and collecting service) and distinguishing collecting quality, we propose two models (decentralized and centralized models) to study the collection strategies and profits of the CLSC. Moreover, we analyze the impact of the collecting competition and quality on the CLSC. Finally, a revenue-cost sharing contract (RCSC) is introduced to coordinate the supply chain. And a numerical example is illustrated to verify the contract's efficiency. It is found that the collected quantities and profits of the CLSC members are positively correlated with the remanufacturable ratio. The collecting competition dampens consumers' enthusiasm for recycling, which is not conducive to collectors to carry out collecting activity, resulting in the reduction of the CLSC's profit. The collectors appropriately improving collecting prices and service levels can increase the collected quantities, but to cope with the increasing competition, increasing collecting price is the main means for collectors to attract consumers to recycle. In addition, the designed RCSC can effectively improve the CLSC's efficiency and increase the profits of each party.
Consensus stability analysis for stochastic multi-agent systems with multiplicative measurement noises and Markovian switching topologies
Authors: Huang Xiaojin , Yang Hongfu , Huang Jianhua
Published: July 2021

We investigate the consensus stability for linear stochastic multi-agent systems with multiplicative noises and Markovian random graphs and investigate the asymptotic consensus in the mean square sense for the systems. To establish the consensus stability for the systems, we analysis the consensus error systems by developing general stochastic differential equation with jumps, matrix theory and algebraic graph theory, and then show that the error consensus in the mean square sense finally tending to zero as time goes on is determined by the strongly connected property of union of topologies. Finally, we provide an example to demonstrate the effectiveness of our theoretical results.
Campaña contra la bidʿa conyugal en el norte de Marruecos durante el siglo XVI
Authors: Shinoda Tomoaki
Published: July 2021

El presente trabajo es una investigación sobre la campaña librada por los eruditos islámicos afiliados a la orden sufí Shādhiliyya-Jazūliyya entre las tribus en la región montañosa del norte de Marruecos en el siglo XVI. Se examina específicamente la campaña de estos eruditos contra bidʿa en las montañas, con un enfoque en sus ataques contra las prácticas tradicionales relacionadas con el matrimonio y la vida conyugal que consideraban religiosa y moralmente aberrante. La fuente primaria discutida aquí es una guía para el matrimonio, titulada Etiqueta de marido y mujer, que contiene diversas doctrinas legales, fatwās, anécdotas, y otros relatos. Basándose en este documento, examinamos el trasfondo ideológico de estos eruditos, los métodos que usaban y los tipos de prácticas que censuraban. Esta campaña tuvo como objetivo realzar la estricta segregación sexual mediante el uso de la autoridad religiosa de los maestros sufíes y ḏikr para vencer la resistencia de las tribus quienes habían permitido que hombres y mujeres se mezclarán públicamente entre sí. También exigió una estructura jerárquica de la educación religiosa, con la familia como base para la islamización de las normas jurídicas en la sociedad tribal. Este trabajo considera que no se siguieron rigurosamente los dictados de los eruditos porque eran incompatibles con el modo de vida en esta región. Parece probable que los líderes de la campaña apoyaron la causa de los Saʿdids porque habían esperado que su actividad procedería mejor bajo un nuevo régimen con un gobierno más eficaz y con mejor control sobre la sociedad.
