Measurement of Cancer-Related Fatigue Based on Heart Rate Variability: Observational Study (Preprint)
Authors: Shih Chi-Huang , Chou Pai-Chien , Chou Ting-Ling , Huang Tsai-Wei
Published: July 2021

BACKGROUND

Cancer-related fatigue is a serious side effect of cancer, and its treatment can disrupt the quality of life of patients. Clinically, the standard method for assessing cancer-related fatigue relies on subjective experience retrieved from patient self-reports, such as the Brief Fatigue Inventory (BFI). However, most patients do not self-report their fatigue levels.

OBJECTIVE

In this study, we aim to develop an objective cancer-related fatigue assessment method to track and monitor fatigue in patients with cancer.

METHODS

In total, 12 patients with lung cancer who were undergoing chemotherapy or targeted therapy were enrolled. We developed frequency-domain parameters of heart rate variability (HRV) and BFI based on a wearable-based HRV measurement system. All patients completed the BFI-Taiwan version questionnaire and wore the device for 7 consecutive days to record HRV parameters such as low frequency (LF), high frequency (HF), and LF-HF ratio (LF-HF). Statistical analysis was used to map the correlation between subjective fatigue and objective data.

RESULTS

A moderate positive correlation was observed between the average LF-HF ratio and BFI in the sleep phase (ρ=0.86). The mapped BFI score derived by the BFI mapping method could approximate the BFI from the patient self-report. The mean absolute error rate between the subjective and objective BFI scores was 3%.

CONCLUSIONS

LF-HF is highly correlated with the cancer-related fatigue experienced by patients with lung cancer undergoing chemotherapy or targeted therapy. Beyond revealing fatigue levels objectively, continuous HRV recordings through the photoplethysmography watch device and the defined parameters (LF-HF) can define the active phase and sleep phase in patients with lung cancer who undergo chemotherapy or targeted chemotherapy, allowing a deduction of their sleep patterns.

The Influence of Gamification and Information Technology Identity on Postadoption Behaviors of Health and Fitness App Users: Empirical Study in the United States (Preprint)
Authors: Esmaeilzadeh Pouyan
Published: July 2021

BACKGROUND

The use of health and fitness apps has been on the rise to monitor personal fitness and health parameters. However, recent research discovered that many users discontinue using these apps after only a few months. Gamification has been suggested as a technique to increase users’ interactions with apps. Nevertheless, it is still not clear how gamification mechanisms encourage continued use and inspire user self-management.

OBJECTIVE

The main objective of this study was to articulate how gamification mechanisms in studies of designing and using health and fitness apps can contribute to the realization of information technology (IT) identity and positive behavioral outcomes. The broader goal was to shed light on how gamification mechanisms will translate into positive use behaviors in the context of mobile health apps.

METHODS

Data were collected from 364 users of health and fitness apps through an online survey to empirically examine the proposed model.

RESULTS

Based on identity theories, this study suggests the fully mediating role of IT identity to describe how gamification elements can lead to continued intention to use health and fitness apps, and increase users’ tendency for information sharing through the apps. The findings indicate that perceived gamification can increase users’ IT identity. In turn, a higher IT identity would encourage users to continue using the apps and share more personal health information with others through the apps.

CONCLUSIONS

The results of this study can have practical implications for app designers to use gamification elements to increase users’ dependency, relatedness, and emotional energy associated with health apps. Moreover, the findings can have theoretical contributions for researchers to help better articulate the process in which gamification can be translated into positive use behaviors.
Left Ventricular Outflow Tract Obstruction in Patients Treated With Milrinone for Cerebral Vasospasm: Case Report and Literature Review (Preprint)
Authors: Baulier Charles , Lessert Marc , Chauvet Jean-Louis , Garel Pauline , Bergis Alexandre , Burdeau Julie , Clavier Thomas
Published: July 2021

UNSTRUCTURED

Subarachnoid hemorrhage is associated with high morbidity and mortality, and cerebral arterial vasospasm is one of its main complications that determines neurological prognosis. The use of intravenous milrinone is becoming more common in the treatment of vasospasm. This molecule has positive inotropic and vasodilating properties by inhibiting phosphodiesterase-3. Its most described side effects are cardiac arrhythmias and arterial hypotension. In this paper, we raise a new issue concerning milrinone and discuss an undescribed side effect of this treatment, left ventricular outflow tract obstruction (LVOTO). Dynamic LVOTO is a clinical situation favored by hypovolemia, decreased left ventricular afterload, and excessive inotropism that can lead to severe hemodynamic failure and pulmonary edema. To our knowledge, this is the first study describing milrinone-induced LVOTO. This could compromise cerebral perfusion and therefore the neurological prognosis of patients. While it is known that catecholamines may induce LVOTO, milrinone-induced LVOTO appears to be a new pathophysiological entity of which neurosurgical intensivists should be aware.
Assessment of Glycemic Control at St. Luke’s Free Medical Clinic: Retrospective Chart Review (Preprint)
Authors: Hopper Wade , Fox Justin , Dimucci-Ward JuliSu
Published: July 2021

BACKGROUND

A free clinic is a health care delivery model that provides primary care and pharmaceutical services exclusively to uninsured patients. With a multidisciplinary volunteer clinical staff, which includes physicians, social workers, dieticians, and osteopathic medical students, St. Luke’s Free Medical Clinic (SLFMC) cares for over 1700 patients annually in Spartanburg, South Carolina.

OBJECTIVE

This study aims to measure the change, over time, in patient hemoglobin A1c measurements at the SLFMC to quantify the success of the clinic’s diabetes treatment program.

METHODS

A prospective-retrospective chart review of patients (n=140) enrolled at the SLFMC between January 1, 2018, and January 1, 2021, was performed. Patients were stratified as having controlled (hemoglobin A1c<7.0, n=53) or uncontrolled (hemoglobin A1c≥7.0, n=87) diabetes relative to a therapeutic hemoglobin A1c target of 7.0, which is recommended by the American Diabetes Association. For both controlled and uncontrolled groups, baseline hemoglobin A1c values were compared to subsequent readings using a Wilcoxon matched-pairs signed rank test. Results from the SLFMC population were compared to the published literature on hemoglobin A1c from other free clinics.

RESULTS

Patients with uncontrolled diabetes experienced significant reductions in median hemoglobin A1c at both 6 months (P=.006) and 1 year (P=.002) from baseline. Patients with controlled diabetes showed no significant changes. Black and Hispanic patients with uncontrolled diabetes experienced a 1.0% mean improvement in hemoglobin A1c over the study window. The SLFMC’s wholly uninsured patient population showed a population rate of controlled diabetes (42%), which was similar to recent nationwide averages for adults with diabetes (51% to 56%), as reported by the National Health and Nutrition Examination Survey. The clinic’s Hispanic population (n=47) showed the greatest average improvement in hemoglobin A1c of any ethnic group from baseline. Additionally, 61% of the SLFMC’s Black population (n=33) achieved a hemoglobin A1c of <7.0 by the end of the study window, which surpassed the nationwide averages for glycemic control.

CONCLUSIONS

We present free clinic hemoglobin A1c outcomes obtained through a retrospective chart review. Uninsured patients treated for diabetes at the SLFMC show a reduction in hemoglobin A1c, which is comparable to nationwide standards, although average hemoglobin A1c levels in this study were higher than nationwide averages. Black and Hispanic patients with uncontrolled diabetes showed a mean 1% improvement in hemoglobin A1c levels. These results represent some of the first in the literature emerging from a free clinic that is not affiliated with a major medical school.

Published: July 2021

BACKGROUND

Training physicians to provide effective behavior change counseling using approaches such as motivational communication (MC) is an important aspect of noncommunicable chronic disease prevention and management. However, existing evaluation tools for MC skills are complex, invasive, time consuming, and impractical for use within the medical context.

OBJECTIVE

The objective of this study is to develop and validate a short web-based tool for evaluating health care provider (HCP) skills in MC—the Motivational Communication Competency Assessment Test (MC-CAT).

METHODS

Between 2016 and 2021, starting with a set of 11 previously identified core MC competencies and using a 5-step, mixed methods, integrated knowledge translation approach, the MC-CAT was created by developing a series of 4 base cases and a scoring scheme, validating the base cases and scoring scheme with international experts, creating 3 alternative versions of the 4 base cases (to create a bank of 16 cases, 4 of each type of base case) and translating the cases into French, integrating the cases into the web-based MC-CAT platform, and conducting initial internal validity assessments with university health students.

RESULTS

The MC-CAT assesses MC competency in 20 minutes by presenting HCPs with 4 out of a possible 16 cases (randomly selected and ordered) addressing various behavioral targets (eg, smoking, physical activity, diet, and medication adherence). Individual and global competency scores were calculated automatically for the 11 competency items across the 4 cases, providing automatic scores out of 100. From the factorial analysis of variance for the difference in competency and ranking scores, no significant differences were identified between the different case versions across individual and global competency (P=.26 to P=.97) and ranking scores (P=.24 to P=.89). The initial tests of internal consistency for rank order among the 24 student participants were in the acceptable range (α=.78).

CONCLUSIONS

The results suggest that MC-CAT is an internally valid tool to facilitate the evaluation of MC competencies among HCPs and is ready to undergo comprehensive psychometric property analyses with a national sample of health care providers. Once psychometric property assessments have been completed, this tool is expected to facilitate the assessment of MC skills among HCPs, skills that will better support patients in adopting healthier lifestyles, which will significantly reduce the personal, social, and economic burdens of noncommunicable chronic diseases.
Pediatric Tele–Home Care Compared to Usual Care: Cost-Minimization Analysis (Preprint)

Published: July 2021

BACKGROUND

Although home hospitalization has been a well-known and widespread practice for some time in the adult population, it has not been the same case in the pediatric setting. Simultaneously, telemedicine tools are a facilitator of the change in the health care model, which is increasingly focused on home care. In a pioneering way in Spain, the in-home hospitalization program of the Hospital Sant Joan de Déu in Barcelona allows the child to be in their home environment at the time they are being monitored and clinically followed by the professionals. Besides being the preferred option for families, previous experience suggests that pediatric home hospitalization reduces costs, primarily thanks to savings on the structural cost of the stay.

OBJECTIVE

The aim of this study is to compare the average cost of a discharge by tele–home care with the usual care and to analyze the main drivers of the differential costs of both care models.

METHODS

A cost-minimization analysis is conducted under a hospital’s perspective, based on observational data, and estimated retrospectively. A historical control group of similar patients in terms of clinical casuistry to children hospitalized at home was used for comparison.

RESULTS

A 24-hour stay at the hospital costs US $574.19, while the in-home hospitalization costs US $301.71 per day, representing a saving of almost half (48%) of the cost compared to usual care. The main saving drivers were the personnel costs (US $102.83/US $284.53, 35.5% of the total), intermediate noncare costs (US $6.09/US $284.53, 33.17%), and structural costs (US $55.16/US $284.53, 19.04%). Home hospitalization involves a total stay 27.61% longer, but at almost half the daily cost, and thus represents a saving of US $176.70 (9.01%) per 24-hour stay.

CONCLUSIONS

The cost analysis conducted under a hospital perspective shows that pediatric tele–home care is 9% cheaper compared to regular hospital care. These results motivate the most widespread implementation of the service from the point of view of economic efficiency, adding to previous experiences that suggest that it is also preferable from the perspective of user satisfaction.
The Effect of Internet-Delivered Cognitive Behavioral Therapy Versus Psychoeducation Only on Psychological Distress in Patients With Noncardiac Chest Pain: Randomized Controlled Trial (Preprint)
Authors: Mourad Ghassan , Eriksson-Liebon Magda , Karlström Patric , Johansson Peter
Published: July 2021

BACKGROUND

Patients with recurrent episodes of noncardiac chest pain (NCCP) experience cardiac anxiety as they misinterpret the pain to be cardiac related and avoid physical activity that they think could threaten their lives. Psychological interventions, such as internet-delivered cognitive behavioral therapy (iCBT), targeting anxiety can be a feasible solution by supporting patients to learn how to perceive and handle their chest pain.

OBJECTIVE

This study aims to evaluate the effects of a nurse-led iCBT program on cardiac anxiety and other patient-reported outcomes in patients with NCCP.

METHODS

Patients with at least two health care consultations because of NCCP during the past 6 months, and who were experiencing cardiac anxiety (Cardiac Anxiety Questionnaire score ≥24), were randomized into 5 weeks of iCBT (n=54) or psychoeducation (n=55). Patients were aged 54 (SD 17) years versus 57 (SD 16) years and were mainly women (32/54, 59% vs 35/55, 64%). The iCBT program comprised psychoeducation, mindfulness, and exposure to physical activity, with weekly homework assignments. The primary outcome was cardiac anxiety. The secondary outcomes were fear of bodily sensations, depressive symptoms, health-related quality of life, and chest pain frequency. Intention-to-treat analysis was applied, and the patients were followed up for 3 months. Mixed model analysis was used to determine between-group differences in primary and secondary outcomes.

RESULTS

No significant differences were found between the iCBT and psychoeducation groups regarding cardiac anxiety or any of the secondary outcomes in terms of the interaction effect of time and group over the 3-month follow-up. iCBT demonstrated a small effect size on cardiac anxiety (Cohen d=0.31). In the iCBT group, 36% (16/44) of patients reported a positive reliable change score (≥11 points on the Cardiac Anxiety Questionnaire), and thus an improvement in cardiac anxiety, compared with 27% of (13/48) patients in the psychoeducation group. Within-group analysis showed further significant improvement in cardiac anxiety (P=.04) at the 3-month follow-up compared with the 5-week follow-up in the iCBT group but not in the psychoeducation group.

CONCLUSIONS

iCBT was not superior to psychoeducation in decreasing cardiac anxiety in patients with NCCP. However, iCBT tends to have better long-term effects on psychological distress, including cardiac anxiety, health-related quality of life, and NCCP frequency than psychoeducation. The effects need to be followed up to draw more reliable conclusions.

Published: July 2021

Wastewater produced from cheese industry is rich in biological component such as whey protein, fat and lactose. Whey protein is the residual liquid of cheese making process with a high protein efficiency ratio. The wastewater source used in this study was whey liquid from cheese processing industry located at West Java, Indonesia. Conversion of soluble whey protein into whey protein microparticle is required to produce food with nutritional value that can be adjusted to the needs of the specific target with high digestibility and palatability. Whey protein was collected by separation technique through heat treatment at specific condition. This was done by changing the heat treatment condition and pH of the samples. Changing the pH of the samples before heat treatment affect the ionic strength of the whey protein hence, altering the properties of the concentrate. This study aims to produce whey protein concentrate heated at various pH level and to observe physicochemical and functional properties of the concentrates. The method used in this research was a descriptive method conducted on three treatments and two replications namely whey protein concentrate production in a pH condition 6.4; 6.65; and 7.0. The parameters observed were physicochemical and functional properties. Furthermore, the result showed that there were decrease in protein content, along with the increasing pH before heat treatment. Microstructure image (SEM) showed a finer particles with the increasing pH. Meanwhile, solubility of the rehydrated samples tends to increase along with the increasing pH. The measurement of functional properties of the samples showed that denatured whey protein produced at different pH before heat treatment have different water holding capacity and a tendency to form bonds between protein particles thereby increasing the viscosity value. These physicochemical and functional properties were suitable for denatured whey protein to be used as a texture controller in whey protein based-food production.

20 years Collaborative Governance and Action Research: Evaluation Process of the Regional Spatial Planning of Mappi Regency, Papua
Authors: Iskandar Doddy Aditya
Published: July 2021

This paper evaluates planners’ capacity to influence the plan-making process where it often involves actors and institutions with various interests. Relegating planners’ roles by providing mere technical inputs to those who seek advice would not alleviate spatial imbalance and unequal power structure embedded in the community. Planners should be reflexive and accountable, as it will lead them to aspire to a contested ideal rather than to simply optimize the current system in which they are in. Drawing from our experience in reviewing regional spatial plan of Kabupaten Mappi, providing an alternative approach to current development strategies would help balancing the local community’s power structure. Planners should master the politics of planning as it would help them influence the decision-making process.

The change in platelet function that occurs in patients during treatment for a new coronavirus infection can be determined using the platelet aggregation method. Objectives. To determine optimal inducer of platelet aggregation and to assess its prognostic significance in intensive therapy of patients with COVID-19 infection. Material and methods. 34 patients with new coronavirus infection were included in group 1, and 30 healthy women were included in group 2. The study of platelet aggregation was carried out by the turbidimetric method with AP2110 analyzer (SOLAR, Results. The area under the aggregation curve was statistically significantly greater in patients in group 1 when using an ADP inducer at a dose of 0.3 μg/ml (69.1 (27.3; 164.4) unit in comparison with 55.3 (31.5; 68.2) units in group 2, p<0.001). When using an ADP inducer in high concentrations of 1.25 and 2.5 μg/ml and an adrenaline inducer in concentrations of 2.5 and 5 μM, the area under the curve in patients with COVID-19 infection was statistically significantly lower compared to group 2. The area under the aggregation curve according to the Hosmer-Lemeshov criterion has been found to be an independent predictor of death in the intensive care unit (Chi-square=5.074, p=0.06 for ADP 0.3 μg/ml and Chi square=15.121, p=0.057 for ADP 0.6 μg/ml). Conclusions. A comparative analysis of platelet aggregation using inducers of ADP, adrenaline and collagen has shown that in patients with new coronavirus infection, the degree of coagulation imbalance should be determined according to the indications obtained with an ADP inducer at a dose of 0.3 and 0.6 μg/ml.
PSYCHOMETRIC PROPERTIES AND DIAGNOSTIC CRITERIA OF THE SCALE FOR POSITIVE SYMPTOMS ASSESSMENT - SAPS IN PATIENTS WITH SCHIZOPHRENIA
Authors:   Grodno State Medical University, Assanovich M.V.
Published: July 2021

Objectives. To assess psychometric properties of Scale for the Assessment of Positive Symptoms (SAPS) and to develop criteria for assessing the severity of positive symptoms in the dynamics of therapy, to clinically verify SAPS metric criteria. Material and methods. The study involved 157 patients with the diagnosis of schizophrenia. Psychometric analysis of SAPS was carried out on the basis of the Rasch metric system with the development of criteria for assessing the severity of positive symptoms based on the index of minimum detectable changes for 95% probability (Minimum detectable change 95% - MDC95%). Clinical verification was conducted by statistical analysis of contingency tables of clinical and metric criteria using the Clinical Global Impression Scale (CGI). Results. All items of SAPS have reasonable level of construct validity. The scale is characterized by moderate reliability (r= 0.84) and high discrimination. Factor analysis has revealed heterogeneity of SAPS metric structure: items in the first group assess hallucinatory and delusional symptoms, items in the second group characterize behavioral disorders and formal thinking disorders. The heterogeneity of SAPS reflects dimensional structure of positive syndrome, which allows to consider total score on the scale as an indicator of this psychopathological construct severity. On the basis of metric approach, criteria for assessing the severity of positive symptoms in the dynamics of therapy have been developed. Statistically significant linear relationship has been found between the levels of SAPS and CGI scales: SAPS has shown higher discriminativeness in assessing severe levels and less marked discriminativeness in assessing low levels of positive symptoms compared to CGI. Conclusions. SAPS has acceptable psychometric characteristics. The developed diagnostic criteria are suitable for the use in clinical practice and research.

Mobile ropeways for carrying out loading and unloading and transport and transfer operations in previously unsettled or inaccessible areas, formed with the help of terminal base stations connected by a single rope system on the basis of self-propelled wheeled or tracked chassis of increased carrying capacity and cross-country ability, are a promising type of lifting and transport equipment ensuring the prompt deployment of the necessary technological tools. The article deals with the layout of the mechanism for installing and fixing the end tower using a folding bar, consisting of two articulated links. A mathematical model has been developed that provides the required normative vertical dimension of a self-propelled base station of a mobile ropeway with the aim of its safe independent movement to the place of deployment of the ropeway along general roads. The analysis of the influence of standard dimensional requirements, design dimensions of the chassis carrying frame and the height of the end tower on the main design dimensions of the articulated folding rod in the transport position is carried out. Calculations have shown that the considered design makes it possible to provide the standard vertical dimension of a base station on a 6-axle self-propelled chassis with an end tower length of up to 18 m.

APUESTAS EDUCATIVAS EN MOMENTOS DE TRANSICIÓN HACIA LA PAZ
Authors: Fernández Guayana Tany Giselle
Published: July 2021

El actual ensayo presenta una reflexión crítica en torno a las apuestas educativas necesarias para los momentos de transición por los cuales está pasando Colombia. El posconflicto es hoy una demanda educativa que requiere de respuesta por parte de los formadores y agentes educativos. Debido a ello, el país tiene como tarea trazar nuevos horizontes de sentido, tomando como base aquellas apuestas que ha logrado instaurar políticamente desde la educación pero que, en medio de los constantes cambios sociales, requieren de mayor atención: los ambientes educativos, el currículo y la cátedra de la paz. No obstante, se hace necesario como elemento transversal, establecer lazos sinérgicos entre los demás agentes que rodean la niñez y la juventud a fin de trascender el escenario de la escuela y, por tanto, la labor formativa de los colombianos que deseamos ser. Es así como se concluye que, en momentos de transición, todo acto educativo debe propender al emprendimiento, a la explotación de la creatividad, a nuevas formas de interacción, al establecimiento de espacios dialógicos, al tejido de las subjetividades, a la configuración de colectivos y, por tanto, al rescate de lo humano.
Practices of the I'adah Zuhur after Friday Prayers in Aceh Besar District: An Analysis with the perspectives of Islamic Law Approaches
Authors: Muthalib Salman Abdul , Amri Furqan , Ali Bukhari
Published: July 2021

This study discusses the practice of i'adah dzuhur after the Friday Prayers in Aceh Besar. I'adah dzuhur is carried out by some people as they see that the performance of Friday Prayers is considered to have ignored several conditions. This leads to some people’s decisions to re-perform the dzuhur prayer. This fact encourages the author to explore reasons that some people consider carrying out the i'adah dzuhur after Friday prayers. In addition, the performance is i'adah dzuhur was also driven by perspectives of Muslim scholars graduated from Islamic traditional boarding schools suggesting that the performance of Friday praying has yet to meet certain level of validity. This study is an empirical juridicial study using the Islamic legal approach. The data for the study was collected through interviews, observation and document analysis. In addition, the data was analyzed using qualitative data analysis procedures. The results showed that the performance of Friday prayers in Aceh Besar has met the rules as mandated in the fiqh. However, some people in Aceh Besar are cautious on the eligibility of the Friday prayer performances. This caution is in regard with the two requirements for the validity of Friday: First, the location between mosques should be adjacent with each other. Second, there should be the minimum number of 40 Friday prayer congregations, and all of them should be well educated on the nature of Friday prayers. As a result of being unsure about the fulfillment of these two conditions and caution (ihtiyati), some people perform the i'adah dzuhur after Friday. Such communal understanding is influenced by the alumni of Islamic traditional Boarding schools (dayah) due to several factors. First, the emergence of Islamic figures from the traditional Islamic boarding school; second, the alumni has been active in various socio-religious activities, and third, the alumni have gained some charisma.
The Petta Kalie’s Contribution in The Development of Islamic Law during The Kingdom of Bone
Authors: Ridhwan Ridhwan , A Nuzul A Nuzul
Published: July 2021

This article examines Petta Kalie's contribution to the development of Islamic law in the Kingdom of Bone. Petta Kalieor qadhi has the same position as an advisor or counselor to the sultan. This was similar to the qadhi al-qudhat in Baghdad, syekh Islam in Turkey, sadar-i azam in India, qadhil malikul adil in Aceh or Wali Songo in Java. This study uses a historical approach to understanding the Islamic law as an analytical tool by looking at Petta Kalie as a collective history that contributes to the development of the Islamic law. The study concluded that there were four contributions of Petta Kalie in the development of Islamic law: affirming the integration of sara’ (Islamic law) and ade’ (adat), such as the sompa, mappacci, barzanji and meppanre tamme traditions. The internalization of the Islamic law with the style of Syafi’i school of thought  was carried out by Patte Kalie assisted by puang imang, katte’, bilal, doja and amil who are in charge of teaching and disseminating the Islamic laws such as marriage, divorce, reconciliation, inheritance distribution, and the management of zakat. In addition, Petta Kalie also promotes women’s equality in the Islamic law, supports female Sultanah to appear as kings and initiates education in studying Islamic sciences especially for women called makkamisi’. Finally, a legal fatwa related to resistance to the Netherlands and refusal to cooperate with them. Some of these arguments and findings are indisputable historical facts that Petta Kalie made a major contribution to the development of Islamic law in the Bugis Bone society.
The Study of Islamic Law About The Deceased Muslim and Its Cultural Symbols in Sumpur Kudus, West Sumatera, Indonsia
Authors: Salma Salma
Published: July 2021

Every living thing dies. The death of a person leaves an obligation for the living to perform some rituals for the deceased. The rituals have been regulated in such a way according to Islamic Sharia (law). Nevertheless, the practices could not be separated from the local traditions and customs. Their influences can be seen through various symbols used in the rituals for the deceased, as found in Sumpur Kudus, West Sumatra. The community has been using many symbols in carrying out the various rituals for the dead, such as kain unduang-unduang (a kind of white cloth stretched above the grave), parian (a bamboo tree that is used as a water container), payuang panji (an umbrella protecting the dead body along the way to the grave) and daun sicerek (a plant used for fragrance). The people stated that, in general, these symbols contain a deep affection of the living towards the deceased. The type of the study was field research with a qualitative approach. The data was gathered by observation, in-depth interviews, and documentation study. The analysis was done descriptively by data reduction, display, and verification (drawing conclusion). The result showed that the Sumpur Kudus community is a Muslim community that does not ignore Islamic law in the organization of their deceased. These symbols serve as tools to show affection of the living towards the deceased. The symbols do not only serve as symbols of affection, but they are also laden with the belief that contain transcendental values.
Understanding Multiple Interpretations on the Hadith that Husbands Allow Wives to have Outdoor Activities: A Study of Islamic Law Perspectives
Authors: M. Jakfar Tarmizi , Fitria Arifah
Published: July 2021

Understanding the interpretation of a hadith is multifaceted, in which the Muslim clerics have multiple perspectives on certain hadith, including hadith on husband’s permission to wife to engage in outdoor activities. This is a library research, in which we explore some literature on this issue. The analysis technique used is descriptive-analytical and comparative, while the approach used is historical-sociological. The focuses of this study are threefold: to understand the mazhab(traditional) scholars’ and contemporary scholars’ perspectives, and to review the Islamic law on the Muslim clerics’ understanding of this issue. This paper concludes that mazhab scholars tend to understand the hadith textually, strictly and non-contextual-that is, asking permission to engage in outdoor activities is an obligation of the wife, otherwise it is considered disobedient to the husband. Meanwhile, contemporary scholars understand the hadith contextually and more flexible. They perceive that asking for permission to do outdoor activities is not an obligation; it is rather a recommendation for wives to seek for their husbands’ permission. In fact, in the recent times, wives working outdoor would in fact support husbands in fulfilling household’s needs. This difference can be understood because historically-sociologically the condition of the society has shifted and transformed. In the past, for instance, when women left the house they would cause danger in the middle of the desert such as robbery or wild animals. Meanwhile, nowadays mass communication and mass transportation have enabled families: husbands and wives to connect with each other. Likewise, when women going outdoor to seek knowledge, attending mosques for congregations, and or going for work, contemporary scholars do not see it as prohibited. Women doing activities outdoor has existed even by the time of the prophet and the companions, showing that most wives work outdoor for family benefits.

Sexual violence was prevalent in many settings, including in religious educational institutions. This article analyzed cases of sexual violence at an Islamic higher education institution in West Java, Indonesia, using the maqasid al-shariah and Foucault's theory of sexuality as the theoretical frameworks. This mixed-method research used Google form's surveys, in-depth interviews, and observations as the data collection methods. The data were analyzed using a flow model, which comprised selection, display, analysis or discussion, and conclusion. This study showed that verbal and non-verbal sexual violence was rampant. It occurred between student and student, lecturer and staff, staff and staff, and lecturer and student. Four models of sexual violence were found based on the typology designed by Dzeich and Weiner, who categorized thirteen forms of sexual violence. The maqasid al-shariah analysis outlined that sexual violence was against the fundamental values and objectives of sharia and human rights. Additionally, Foucault's theory identified patriarchal and cultural hegemony aspects in sexual violence. This study's intriguing part was the findings that combined in-depth interviews, observations, and surveys, intended to understand the intensity of existing cases. On the other hand, the power of analysis was centered on normative fiqh and sociological aspects. According to the literature reviews, these two approaches had not been administered by previous researchers.

Authors: Zada Khamami , Irfan M. Nurul
Published: July 2021

The European Muslims, the majority of them come from Muslim countries, are facing the identity dilemma. On the one hand, they are the Muslims who are obliged to carry out their religious teaching, but on the other hand, they are the Muslims who have acquired European citizenship who cannot enforce religious laws and instead submit to secular state laws. The study analyzes French and Germany Muslim aspirations and their negotiations on carrying out sharia in the secular state. This is field study by qualitative approach. Primary data was collected by interviews with Muslims of Moroccan, Tunisian, Algerian, and Turkish descent living in France and Germany. The study found that French and German Muslims want to apply sharia, but France and Germany do not allow religious law to be made a state law. These have left French and German Muslims to negotiate without opposition, resistance, and conflict. As European citizens, they accept secular law without losing their religious and social identity, though couldn’t fully implement Sharia.

Published: July 2021

Este artigo objetiva analisar, a partir do método marxista, o perfil e as condições de trabalho de Assistentes Sociais. Trata-se do resultado de uma pesquisa de caráter misto, realizada em 2019-2020, com Assistentes Sociais ativos das Seccionais do CRESS 10ª Região, para a qual realizou-se pesquisa bibliográfica, grupos focais e aplicação de questionário. Utilizou-se a análise de conteúdo e do tipo inferencial para o tratamento dos dados. Os resultados indicaram que o perfil de Assistentes Sociais é majoritariamente composto por mulheres (84,58%) brancas (74,86%), casadas (41,35%) ou em união estável (16,9%), formadas presencialmente (72,41%) e que estão trabalhando na área (81,68%). A maioria está inserida no âmbito das políticas sociais de seguridade social, 78% em Pelotas e 83% em Caxias do Sul, sendo a política de Assistência Social a de maior inserções, 58,79%. O vínculo estatutário em Caxias do Sul (51,26%) é maior que em Pelotas (49,33%). Identificamos outros vínculos como o temporário, o terceirizado e o intermitente que se intensificam durante a pandemia. Podemos concluir que as transformações do mundo do trabalho implementadas no Brasil vêm repercutindo na classe trabalhadora, e, portanto, no trabalho dos(as) Assistentes Sociais suscitando desafios que requerem estratégias coletivas para o seu enfrentamento.
ATUAÇÃO DO SERVIÇO SOCIAL COM POPULAÇÃO LGBT EM CONTEXTO ULTRACONSERVADOR E PANDÊMICO
Authors: Dantas Michael Hudson , Souza Luana Vanessa Soares Pinto de , Pinheiro Samya Katiane Martins
Published: July 2021

O objeto de análise desse estudo são as implicações do contexto ultraconservador e pandêmico para a atuação profissional do (a) assistente social no processo de atendimento e intermediação do acesso aos direitos da população LGBT a partir da experiência de atuação no Centro Municipal de Cidadania LGBT de Natal/RN. A metodologia utilizada parte da reflexão ética, por meio de reuniões e estudos temáticos a partir das demandas do Centro LGBT de Natal/RN e a análise bibliográfica, tendo em vista apreensão crítica da totalidade da vida social. Assim, temos o entendimento que o aprofundamento da desigualdade social, em tempos de pandemia sanitária é parte fundamental da sociabilidade do capital e o ataque orquestrado pela classe dominante heteropatriarcal e racista contra a vida de trabalhadores (as), em toda sua diversidade, é inerente ao projeto de hegemonia social do capital, o que impacta, indiscutivelmente, o exercício profissional de assistentes sociais, uma vez que essa atuação é direcionada ao enfrentamento das expressões da questão social e se pauta em projeto contra hegemônico de sociedade.
EXPLORAÇÃO TRIBUTÁRIA, OU, COMO O TRABALHO NECESSÁRIO SUSTENTA O FUNDO PÚBLICO
Authors: Nogueira Yan Carlos
Published: July 2021

Resumo: O presente artigo levanta reflexões sobre o fundo público como terreno de disputas entre as classes sociais. Para tal, em termos metodológicos, recorremos a revisão bibliográfica, ancorados em autores que têm se debruçado sobre o tema. Na primeira parte, centramos nossa atenção em discorrer sobre o caráter do fundo público no capitalismo monopolista, colocando em destaque o papel do estado na sua mediação e o movimento – entre o “privado” e o “público” – das lutas de classes. Na segunda, buscamos qualificar a constatação de que o fundo público é sustentado pelo trabalho necessário, a partir da maior presença de impostos indiretos que incidem sobre o consumo. Nosso intuito, todavia, foi o de problematizar o conceito de “exploração tributária”, recorrentemente utilizado para designar esse fenômeno. Estamos convencidos de que não é possível falar de exploração em matéria de tributação, visto que o que se opera é apenas uma mobilização de recursos presentes na esfera da circulação que não gera mais-valor. Diante desses elementos, concluímos com a exposição de alguns dados acerca do Brasil que ilustram a exposição teórica feita ao longo do texto.

Palavras-chave: Estado. Fundo Público. Esfera Pública. Lutas de classes. “Exploração Tributária”.
