MULHERES E DIREITOS HUMANOS: uma perspectiva normativa acerca do enfrentamento da violência de gênero
Authors: Alencar Gabriela Serra Pinto de , Locatelli Laís , Aquino Maria da Glória Costa Gonçalves de Sousa
Published: December 2022

Objetiva discutir a violência de gênero enquanto uma violação dos direitos humanos das mulheres. Considerando a escassez de estudos que abordem a temática sob o aspecto internacional, propõe-se a traçar um panorama dos instrumentos normativos de enfrentamento à violência contra as mulheres em âmbito internacional e seus impactos na adoção de políticas públicas pelo Brasil. Reflete acerca das contradições no processo de efetivação das disposições normativas e nos desafios a serem rompidos para garantir a integridade da mulher, não só física. Aborda, em específico, a violência sexual que, à despeito de ser considerada como um problema de saúde global pela Organização Mundial da Saúde (OMS), ainda apresenta elevados índices de ocorrência e esbarra na fragilidade dos sistemas de justiça. Elenca sujeitos de políticas públicas diversos que contribuíram para a promulgação dos marcos regulatórios a serem discutidos, com destaque aos movimentos de mulheres e aos organismos internacionais.
O SISTEMA DA DÍVIDA PÚBLICA, A CONTRARREFORMA DA PREVIDÊNCIA E O RISCO PARA A SEGURIDADE SOCIAL
Authors: Gonçalves Filho Antônio , Gomes José Menezes , Fattorelli Maria Lúcia , Alencar Júnior Osmar Gomes de
Published: December 2022

Desde o governo de FHC (1994-2002) até os governos de Lula-Dilma (2003-2015), a Previdência com maior ou menor grau é apresentada para a sociedade como deficitária e o Estado como incapaz de mantê-la. Inúmeros estudos demonstraram que este não passa de um discurso ideológico, cujo objetivo central trata de uma aberta privatização da previdência social. O governo Bolsonaro, com bases em falsas notícias, apresenta uma proposta de “reforma” da previdência que coloca em risco o Sistema de Seguridade Social. Além de dificultar o acesso aos benefícios previdenciários dos mais pobres, mantendo os privilégios dos mais ricos, a proposta desestrutura e asfixia financeiramente a seguridade social para alimentar o sistema da dívida pública, que remunera cada vez mais os banqueiros e rentistas nacionais e internacionais. É necessária uma ampla discussão na sociedade, para que se desvelem as verdadeiras intenções por trás da contrarreforma privatista.

Do inhaled or oral glucocorticoids more effectively control feline asthma?
Authors: Williams Savannah
Published: December 2022

PICO question

In cats with chronic bronchospasm and airway hypersensitivity (asthma) do oral glucocorticoids or inhaled glucocorticoids more effectively control the clinical signs?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

Three prospective randomised clinical trials were appraised. Two of the studies followed a crossover design and had a control group, whilst the third study described an interrupted time series

Strength of evidence

Weak

Outcomes reported

The available studies deemed a reduction in eosinophilia on bronchoalveolar lavage fluid analysis, and a reduction in airway resistance as markers of treatment efficacy

Conclusion

There is weak evidence to suggest equal treatment efficacy of oral and inhaled glucocorticoid therapy for management of feline asthma. Higher powered studies would be required before a definitive recommendation can be made

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

Knowledge Summaries are a resource to help reinforce or inform decision making. They do not override the responsibility or judgement of the practitioner to do what is best for the animal in their care.
An Analysis of the Relationship Between Self-Compassion, Psychological Inflexibility, Psychological Health, and PTSD Severity in a Partial Hospitalization Program
Authors: Grau Peter P. , Adams Thomas G. , Wetterneck Chad T.
Published: December 2022

PTSD symptoms and psychological inflexibility have been linked to a lack of self-compassion and poor psychological health. Prior work has explored these relationships in a trauma-exposed undergraduate population and found that, while self-compassion was correlated with PTSD symptom severity at the bivariate level, this relationship was no longer significant when accounting for psychological inflexibility. Additionally, self-compassion and psychological inflexibility predicted psychological health. The present study sought to test these findings in PTSD patients enrolled in an exposure-based partial hospitalization program. Acceptance and Commitment Therapy (ACT)-consistent measures (i.e., Valued Living Questionnaire, Behavioral Activation for Depression Scale [Short Form], Quality of Life Enjoyment and Satisfaction Questionnaire [Short Form]) were used to assess psychological health. The PTSD checklist for DSM-5 and the Acceptance and Action Questionnaire (II) were used to measure PTSD symptoms and Psychological Inflexibility, respectively. Our results were largely consistent with previous investigations. We found a negative relationship between psychological inflexibility and psychological health, as well as a positive relationship between psychological inflexibility and PTSD symptom severity. Future research should measure these constructs across different time points to explore the benefit of viewing self-compassion and other related constructs (e.g., courage and love) as values in an ACT model for PTSD treatment.

A Cayley-Dickson-féle mátrixok algebrájáról
Authors: Péntek Kálmán
Published: December 2022

Minden véges dimenziós asszociatív algebra a teljes mátrixalgebra egy alkalmas részalgebrájával reprezentálható. Ismertek azonban olyan véges dimenziós algebrák, amelyek nem asszociatívak, így nem írhatók le klasszikus mátrixok segítségével. Max August Zorn 1931-ban értelmezte a vektor-mátrixok struktúráját, amelyek a klasszikus mátrixok egy természetes általánosítását alkotják. Zorn a split oktoniók alternatív algebráját eredményesen írta le ezen vektor-mátrixok segítségével. Mi egy tetszőleges, nem kettő karakterisztikájú 𝐹 test fölé építünk vektor-mátrix struktúrát, s megvizsgáljuk a legfontosabb algebrai tulajdonságait. Ha az 𝐹3 vektortérben alkalmas skaláris és vektoriális szorzat van értelmezve, akkor a felépített vektor-mátrixok struktúrája egy alternatív algebra lesz akkor és csakis akkor, ha az 𝐹3 vektortérben érvényes a Grassmann-azonosság. E vektor-mátrixok struktúrája viszont egy kompozíciós algebrát alkot akkor és csakis akkor, ha az 𝐹3 vektortérben a Lagrange-azonosság teljesül.

This study focuses on bibliometric indicators of Islamic accounting research development, such as trends in Islamic accounting research and its distribution, topics and themes in Islamic accounting research, significant contributors to Islamic accounting research, the pattern of collaboration in Islamic accounting research, and the most significant texts in the Islamic accounting literature. Four hundred eighty-three pieces of scientific literature were entered into the Scopus database for bibliometric analysis on January 10, 2022. Various programs were used to analyze frequency, metrics, and citations, including Microsoft Excel, VOS viewer, and Harzing's Publish or Perish. Over the last ten years, Islamic accounting publications have grown significantly and steadily. Islamic accounting literature is based in Asia, Europe, America, and the Middle East, and it can be found in social science, business, management, accounting, economics, and finance. With a few exceptions in Malaysian, Arabic, German, Indonesian, Slovak, and Turkish, the majority of Islamic accounting literature is written in English. The study also discovered that terms like Islamic bank, banking, Islamic performance, Islamic accounting standards, and Islamic finance are commonly used. The seven countries that contributed the most to the development of scholarly collaborations in Islamic accounting were Malaysia, Indonesia, the United States, Saudi Arabia, the United Kingdom, Pakistan, and Australia. This is critical in assisting academics in making recommendations for future study in the field of Islamic accounting.
THE SECTORAL FINANCING DIVERSIFICATION AND THE PROFITABILITY OF ISLAMIC BANKING IN INDONESIA
Authors: Widarjono Agus , Sidiq Sahabudin Sidiq
Published: December 2022

This study investigates the influence of sectoral financing concentration on the profitability of Islamic banking in Indonesia. The data is aggregated by Indonesian Islamic banks from January 2015 to June 2021. Islamic banks are divided into two, namely Islamic commercial banks and Islamic window banks. The study used Autoregressive distributed lag (ARDL) and Panel Mean Group (PMG). The results showed that sectoral financing concentration increased the profitability of Islamic commercial banks while diversification of sectoral financing boosted the profitability of Islamic window banks. In addition, this study also showed that size and inefficiency negatively affected the profitability of Islamic commercial banks and window banks. This result implies that the right sectoral financing policy for Islamic commercial banks is financing concentration. This strategy implies that Islamic commercial banks must build competitiveness in certain sectors of the economy. For this reason, there is a need to increase the skills of the worker to build a competitive advantage in the sector that is the focus of financing. In comparison, sectoral financing diversification is more applicable for Islamic window banks. To support this diversification strategy, banks must conduct good supervision in the financing, especially sectoral financing based on profit-sharing contracts.

Kale (Brassica oleracea) contains some nutritional values like: vitamin C, pro vitamin A (carotenoids), and some compound belong to polyphenol are flavonoids that benefit to its consumer for the growth and health of the body. Polyphenols are bioactive molecules which play an essential role in plants response to ultraviolet irradiation, and high temperature. Flavonoids comprise the most studied group of polyphenols. This group has a common basic structure consisting of two aromatic rings bound together by three carbon atoms that form an oxygenated heterocycle. In order to support growth and increase it’s productivity, cultivation of Kale supposed to be done in good planting media. The addition of organic subtances like humic acid in planting media has proven to increase plant growth and increase productivity in several plants. The objectives of this research were to know the influence of the influence of humic acid on the growth of plant varieties and polyphenol content and to determine the best concentration of humic acid in increasing growth and polyphenol content. The current research method was carried out experimentally a completely randomize design in a split plot method. The main plot was plant’s varieties in 2 levels: V1: Kale Nero toscana (Brassica oleracea var. palmifolia), V2: Siberian dwarf Kale (Brassica oleracea Var. Sabellica). while the sub plot was the HA concentrations in 4 levels i.e 0 g.kg-1, 4 g.kg-1, 8 g.kg-1, and 12 g.kg-1 of planting medium, The parameters used in this study are fresh and dry weight.

One of the aims of the care service in the Intensive Care Unit (ICU) is to prepare patients in end-of-life conditions to die in a dignified manner. This can be challenging due to decision-making problems and result in a dilemma. Therefore, this study explores the ethical dilemmas experienced by nurses that provide end-of-life care in the ICU. The qualitative phenomenological methodology was used to describe the ethical dilemmas nurses face during these conditions. The data were collected through in-depth interviews and were analyzed using Colaizzi. Purposive sampling was used to select a total of eight participants, i.e., ICU nurses, who have treated end-of-life patients. Four themes were obtained from this study, namely, “the dilemma between the family’s decisions and continuing care”, “patient’s life expectancy and the family’s hope”, “DNR decisions and the nurse’s confidence”, and “the family’s understanding of the information provided”. This study recommends that the assessment of end-of-life status in critical care areas, especially the ICU, should be conducted as soon as possible to have a clearer purpose for the care provided.

Many women living with HIV intend to become pregnant. This is especially true for women who have received ARV treatment for a certain period. The purpose of this study was to explore the perspectives of nurses and Thai pregnant women living with HIV on pregnancy decision-making processes. This is a descriptive and qualitative study. Small group discussions were conducted with five nurses working with HIV-positive women and in-depth interviews were conducted with five Thai HIV-positive pregnant women. A model of the pregnancy decision-making process was provided to participants for the discussion. The nurses’ and women's perspectives on the model can be divided into two themes: 1) The perspective of the selected model and its five sub-themes, namely: 1.1) How the substantive model reflects the pregnancy decision-making process; 1.2) Complexity; 1.3) Usability; 1.4) Strength; 1.5) Weaknesses, in addition to the perspectives of women and nurses on the application of the model. The model reflects the real-life experiences and decision-making processes of Thai women with HIV, where each category shows the trail of the women's decision-making process. However, the model is complex and requires substantial explanation. From the participant's point of view, the model reflects the barriers to the practices and services provided.

This study aimed to determine the relationship between COVID-19 prevention measures and the quality of life for the elderly with hypertension during the COVID-19 pandemic. This was a descriptive correlation study that applied a cross-sectional approach that involved 133 respondents who were selected using the convenience sampling technique. Data were collected using questionnaires from the World Health Organization Quality of Life – BREF (WHOQOL-BREF) and COVID-19 prevention measures. The collected data were processed using the Chi-Square test in univariate and bivariate analyses. The results showed that the number of elderly participants who took positive and negative efforts in preventing COVID-19 transmission was almost equal, with a slightly higher number of participants taking positive efforts with a total of 69 people (51.9%). There was also a higher number of elderly participants who had a good quality of life with 71 people (53.4%). The Chi-Squared test results indicated a relationship between COVID-19 prevention measures and the quality of life of elderly patients with hypertension during the COVID-19 pandemic with a p-value of 0.008. Therefore, it can be concluded that prevention efforts in the form of health behaviors for the elderly with certain chronic diseases comorbid with COVID-19 can affect their quality of life.

Anthropogenic activities have the potential to put pressure on the marine environment. Crude oil was one of the pressure that give rise to any response of the aquatic organism, such as sound. This study aimed to analyze the sound productivity of spiny lobster Panulirus homarus (Linnaeus, 1758) in waters contaminated with crude oil. Observation of lobster sound was carried out on a laboratory scale using the passive acoustic method. A hydrophone and Closed Circuit Television (CCTV) camera coupled with a decoder and personal computer used to record the movements and sounds of P. homarus during the treatment of crude oil at concentrations 1; 5; 10 and 100 mgL-1. The result showed that crude oil contamination in water was impacted the sound productivity of P. homarus. In the low concentration of crude oil (1 - 5 mgL-1), P. homarus was responded with more sound produced. Afterwar, until concentration off 10 mgL-1, the response of P homarus showed different between individuals. In the 100 mgL-1 concentration, the sound productivity of all P. homarus was decreased. Based on this study, we concluded that the sound of P. homarus has the potential as an indicator of water pollution.Keywords: Panulirus houmarus, crude oil, fish sound

Ammonia (NH3) is one of the impurities in salt-producing water, which is often found in the traditional salt ponds of the Madurese. The purpose of this study was to determine the concentration of ammonia contamination as an impurity in salt production process water from raw water, reservoir ponds, evaporator ponds to geomembrane crystallizer ponds when salt production takes place in the salt ponds of Tanjungan Village, Bangkalan Regency. Determination of ammonia concentration using the phenate method based on SNI 06-6989.30-2005 with a spectrophotometer reading tool (UV-2700 Serial No. A11674900027) at a wavelength of 420 nm. The average concentration of ammonia as an impurity in raw materials in traditional pond ponds in Tajungan village, namely raw water is 2.31Â±0.24 mg/L, reservoir ponds are 2.56Â±0.57 mg/L, evaporator ponds are 2, 39Â±0.84 mg/L and the geomembrane crystallizer ponds are 1.37Â±0.09 mg/L. The highest average ammonia concentration was found in the reservoir ponds raw saltwater sample, while the lowest concentration was found in the geomembrane crystallizer ponds sample. The high average ammonia concentration in the salt ponds of Tajungan Village, Bangkalan Regency indicates that all raw saltwater in these ponds is contaminated with ammonia. The high concentration of ammonia in the salt ponds may be due to the entry of household waste.Â Keywords: (NH3), raw water, reservoir ponds, evaporation ponds, geomembrane crystallizer ponds
