Dinas Penanaman Modal dan Pelayanan Satu Pintu Kota Jambi adalah instansi pemerintah yang mempunyai kewenangan yang bersifat konkuren. Tugas dari Dinas ini  ialah menberikan pelayanan terhadap penanaman modal dan pelayanan perizinan serta non perizinan di Kota Jambi. Dalam pembuatan Surat Izin Tempat Usaha (SITU) khususnya izin usaha pada hiburan umum yang memanfaatkan ruang perkotaan harus berdasarkan konsep dari tata ruang perkotaan sesuai dengan peraturan perundang-undangan yang berlaku. Penelitian ini bertujuan untuk mengetahui bagaimana pembuatan dan penegakan sanksi administrasi terhadap penerbitan SITU khususnya izin usaha hiburan umum. Penelitian ini merupakan penelitian yuridis normatif yang bersifat deskriptif kualitatif. Hasil penelitian memperlihatkan bahwa penerbitan SITU Kota Jambi tidak didasarkan pada konsep tata ruang yang telah diatur didalam PERDA. Hal ini terjadi karena dalam Peraturan Daerah Kota Jambi Nomor 9 Tahun 2010 Tentang Rencana Tata Ruang Wilayah (RTRW) Kota Jambi terdapat ketidakjelasan norma yang mengakibatkan timbulnya penafsiran dan pemahaman yang berbeda terhadap persyaratan pembuatan SITU. Hal ini disebabkan oleh (1) adanya norma yang melahirkan ketidakjelasan dalam pengambilan keputusan pejabat Tata Usaha Negara (TUN) yang menimbulkan kerugian pada masyarakat berupa gangguan di wilayah tempat usaha tersebut berdiri, (2) adanya tindakan terhadap penegakan hukum administrasi yang berupa keputusan. Saran untuk pejabat pemerintah Kota Jambi yang berwenang untuk merevisi atau memperbaiki Peraturan Daerah Nomor 9 Tahun 2013 Tentang Rencana Tata Ruang Wilayah Kota Jambi mengenai isi dalam pengaturan kawasan peruntukan perdagangan dan jasa serta ketentuan perizinan agar usaha-usaha yang memanfaatkan ruang Kota Jambi dapat terarah sehingga terpenuhinya hak-hak dan kewajiban masyarakat sekitar khususnya Kota Jambi dalam pembangunan, pelaksanaan, dan pengawasan tata ruang Kota Jambi.

A didática da matemática, nestes quase 50 anos, vem desenvolvendo modelos conceituais e um vocabulário específico cuja complexidade é adaptada à complexidade dos fenômenos do ensino e da aprendizagem dos saberes. Esta complexidade, como em toda ciência, dificulta a disseminação da pesquisa em didática da matemática, nos diferentes estratos da sociedade. Pensando neste desafio, este artigo se situa na dimensão da popularização da ciência, um problema difícil, de natureza didática, que não pode ser ignorado pela comunidade em didática da matemática. Considerando o artigo da Maria Rita Otero, onde a mesma apresenta o significado para o termo situação, em diferentes teorias, apresentaremos aqui exemplos de situações à luz destas diferentes teorias objetivando contribuir para popularização da didática da matemática. Acreditamos que com este trabalho poderemos contribuir para o enfrentamento do fenômeno do vazio didático.

A ciência forense foi utilizada de modo a capturar a atenção dos alunos e propiciar uma apresentação dos temas inter-relacionados das disciplinas de física, química e biologia a partir de perspectivas cotidianas e reais. Segundo o enfoque na Teoria da Aprendizagem Significativa de David Ausubel, buscou-se a aplicação de temáticas do senso comum que pudessem constituir o maior número de subsunçores presentes na estrutura cognitiva dos alunos. Obteve-se como resultado da aplicação de questionários ante e pós conclusão do minicurso, uma significante melhora de 83 alunos do total de 92 participantes. A percepção que se teve do processo de ensino-aprendizagem obtido no presente trabalho, foi de que o mesmo se deu de forma mais concreta e dinâmica para os alunos, e que a relação entre discente – docente é vital para o conhecimento de características individuais de cada estudante, e portanto, conseguindo identificar suas respectivas realidades, de modo a acarretar em melhorias no desenvolvimento do processo educacional.
O DEBATE ENTRE INTELECTUAIS MARXISTAS SOBRE CIÊNCIA, CULTURA E LUTA DE CLASSES NOS MEADOS DO SÉCULO XX
Authors: Loula Dourado Viana Marta
Published: June 2022

Este texto analisa o debate entre intelectuais marxistas sobre ciência, cultura e luta de classes nos meados século XX. No contexto da política anticomunista e retrocesso democrático no Brasil, de intensificação das forças hegemônicas do capitalismo estadunidense na exploração dos recursos naturais e do trabalho. Esta conjuntura impôs a necessidade de defesa nacional de modo particular e polarizado nas produções artístico-culturais e científicas. O posicionamento político e a abordagem da realidade brasileira tornaram-se condições para superar o abstrato, o elitismo e as ilusões nas produções intelectuais bem como contribuir para o processo de transformação social. Este debate se caracterizou, por um lado, complexo devido ao voluntarismo político e aos embates entre os intelectuais marxistas brasileiros, por outro lado, enriquecedor e promotor de um salto artístico-cultural e científico por considerar à realidade sociocultural do país e representação do povo brasileiro.
RETORNO ELEITORAL DO PROGRAMA BOLSA FAMÍLIA NA ELEIÇÃO PRESIDENCIAL DE 2018: UMA ANÁLISE PARA DIFERENTES GRUPOS DE MUNICÍPIOS
Authors: Machado Lopes Roberto Paulo , Gonçalves Souto Lucas
Published: June 2022

Este estudo investiga a existência de condicionantes que potencializam o retorno eleitoral do Programa Bolsa Família (PBF). Para tanto, e tendo como base de análise a votação de Fernando Haddad em cada município no segundo turno da eleição presidencial de 2018, estima e avalia coeficientes de retorno eleitoral do PBF para diferentes níveis do Índice de Desenvolvimento Humano Municipal (IDHM). A hipótese básica é que o retorno eleitoral do bolsa família é influenciado pelo IDHM e que existe uma possível não-linearidade nesse retorno. O objetivo é encontrar o IDHM em que ocorre a inversão na tendência dos retornos eleitorais do PBF. O estudo apoia-se nos modelos de ciclos eleitorais, mais especificamente no modelo de controle eleitoral. Os coeficientes são estimados por meio do método dos Mínimos Quadrados Ordinários (MQO). Os dados são de corte transversal (cross section) e a amostra é formada por 5.452 observações. Os principais resultados mostram que existe uma inversão na tendência dos retornos eleitorais do PBF em relação ao IDHM para o caso geral, mas não é possível concluir que o índice de desenvolvimento dos municípios influencie os retornos do PBF quando são considerados apenas municípios com elevada participação de famílias no programa.

Authors: Menezes Laiane Barros dos Santos , Rehem Faní Quitéria Nascimento
Published: June 2022

Gênero é uma categoria que abarca idealizações que foram construídas e desenvolvidas na sociedade a partir um determinado espaço e período, também pode ser entendida por problematizações das diversas ações que organiza a vida dos indivíduos no mundo. Neste trabalho gênero se sustenta como um princípio que é sistemático e complexo, sua compreensão é histórica. Trata-se de um recorte de um trabalho de monografia, uma pesquisa de abordagem qualitativa do tipo documental. Teve como objetivo analisar a existência da discussão política educacional sobre gênero na Educação Infantil nos principais documentos nacionais de Educação. Os referenciais que se destacam nesse trabalho são: Vianna, Louro (1997), Hooks (2019). Nesse sentido, compor estudos acadêmicos sobre gênero assinala um propósito de resistência diante das diversas ameaças conservadoras que vêm sendo postas em nosso país. Todo o percurso encaminhou-se para levantar algumas questões sobre como tem se desenvolvido o debate de gênero nas políticas educacionais no viés da infância, a fim também de colaborar com os diversos estudos já existentes no campo educacional.
Entre as médias e pequenas, a dinâmica das cidades sub-regionais na Bahia
Authors: Santos Janio
Published: June 2022

O texto avalia as características e papéis das chamadas cidades sub-regionais, aquelas que transitam entre pequenas (que não apresentam funções regionais) e as médias (que se articulam a lógicas escalares mais amplas). Na Bahia, há várias cidades sub-regionais e face às políticas de descentralização/desconcentração econômicas e administrativas elas adquiriram novos papéis ao receber estabelecimentos estatais de gestão regional. Em certos casos, sediam filiais de empresas, empreendimentos imobiliários, etc. Espera-se com este artigo permitir novos olhares sobre tais cidades existentes na Bahia e, certamente, em outras partes do Brasil, para avançar na elaboração de um conceito ou mesmo noção que permita melhor compreender os seus traços, lógicas e articulações, o que, consequentemente, evitaria, do nosso ponto de vista, generalizações incorretas.

Published: June 2022

A universalização do direito à aposentadoria rural no Brasil é recente. O sistema de proteção social antes da Constituição Federal de 1988 possuía exigências que segregava os pequenos agricultores familiares. Diante disso, o presente trabalho busca refletir num viés empírico-analítico, o processo histórico da previdência rural no Brasil e seus impactos socioeconômicos na vida dos agricultores familiares no município de Itabaiana-SE. Os procedimentos metodológicos perpassaram por reflexões teóricas, levantamentos de dados e trabalho de campo. No recorte espacial estudado em 2020, segundo o INSS, existiam 2.989 aposentados urbanos e 6.364 rurais. Fato que demonstra a importância socioeconômica que a previdência tem na vida dos atores sociais que vivem no meio rural de Itabaiana-SE e na redução da pobreza no Brasil.

Published: June 2022

Na crise capitalista, há intensificação dos conflitos pelos recursos ambientais, provocando a exploração da natureza. A concentração de terras e o assalariamento altera os princípios do trabalho concreto, gerando o estranhamento. No município de Encruzilhada/BA, o eucalipto na lógica da extração de madeira para produção de carvão vegetal exporta os recursos naturais provocando a insustentabilidade desse modelo. A relação sociedade-trabalho-natureza se torna fundamental para explicar as formas de sujeição dos camponeses ao capitalismo, essa compreensão possibilita o entendimento do real concreto vivenciado no território do agronegócio. Com esses embates, os camponeses buscam resistir, permanecendo no campo, através das organizações da sociedade civil, via associativismo, movimentos sociais, organizações não governamentais e Igrejas.
Assisted dispersal and reproductive success in an ant species with matchmaking
Authors: Vidal Mathilde , Heinze Jürgen
Published: June 2022

Workers of the ant Cardiocondyla elegans drop female sexuals into the
nest entrance of other colonies to promote outbreeding with unrelated,
wingless males. Corroborating results from previous years we document
that carrier and carried female sexuals are typically related and that
the transfer initially occurs mostly from their joint natal colonies to
unrelated colonies. Female sexuals mate multiply with up to seven
genetically distinguishable males. Contrary to our expectation, the
colony growth rate of multiple-mated and outbred female sexuals was
lower than that of inbred or single-mated females, leading to the
question of why female sexuals mate multiply at all. Despite the obvious
costs, multiple mating might be a way for female sexuals to “pay rent”
for hibernation in an alien nest. We argue that in addition to evading
inbreeding depression from regular sibling mating over many generations,
assisted dispersal might also be a strategy for minimizing the risk of
losing all reproductive investment when nests are flooded in winter.

Objective: Gestational hyperglycemia is associated
with deleterious neonatal outcomes, but long-term risks for offspring obesity
are less clear. We estimated the odds for offspring adolescent overweight and obesity
among mothers with gestational glucose intolerance.

Research Design and Methods: In a mother-offspring,
historical cohort, the Israel military conscription dataset was linked to a
large health maintenance organization. Included were women who were evaluated at
adolescence and performed two-step gestational diabetes screening (mean age, 31
years) with a 50-g glucose challenge test (GCT), followed by a 100-g oral glucose
tolerance test (OGTT) if abnormal. Glucose tolerance categories included gestational
normoglycemia, abnormal GCT with normal OGTT, impaired glucose tolerance (IGT;
one abnormal OGTT value), and gestational diabetes. The primary outcome was
offspring overweight/obesity (BMI≥85th percentile) at adolescence,
measured prior to military conscription. Logistic regression models were
applied.

Results: Of 33,482 mother-offspring
pairs, overweight and obesity were observed in 6,516 offspring. Across
increasing categories of pregnancy glycemia, the proportions of offspring with
adolescent overweight/obesity increased: normoglycemia, 19%; abnormal GCT with
normal OGTT, 22%; gestational IGT, 24%; and gestational diabetes, 25%, P<0.0001.
Corresponding odds ratios after adjustment for mother’s late-adolescent
characteristics (sociodemographic confounders and BMI) and pregnancy age were 1.2
(95%CI, 1.1-1.4), 1.3 (1.2-1.5), and 1.4 (1.3-1.6), respectively. Further
adjustment for offspring birth weight percentile and sociodemographic variables
did not materially change results. Associations were more pronounced with
increasing obesity severity.

Conclusions: Gestational glucose intolerance, including categories not meeting the
gestational diabetes threshold, were associated with increased odds for
offspring overweight/obesity at late adolescence.
Propuesta de un modelo de evaluación integral para cursos en línea en la institución educativa Cenid
Authors: Santillán Castillo Francisco Michael
Published: June 2022

El presente trabajo surge de un proyecto macro del Centro de Estudios e Investigaciones para el Desarrollo Docente (Cenid) titulado “Integración de las TIC a la actividad docente universitaria”. El objetivo fue presentar una propuesta metodológica para realizar los elementos de diseño, evaluación y seguimiento de un curso en línea a impartirse entre los docentes de la institución en cuestión. Se trata de una investigación exploratoria descriptiva cuya finalidad fue la de contribuir al establecimiento de lineamientos curriculares y pedagógicos para la creación de cursos en línea. Para validar el curso se implementó un curso piloto y al final de este una encuesta. Los resultados obtenidos indican que para los involucrados el curso piloto fue enriquecedor y de provecho para su trayectoria profesional. Como ventajas más importantes están la realización de actividades prácticas, la gran participación en los foros de debate, las actividades elaboradas por cada profesor, la claridad y la calidad de sus presentaciones, así como la calidad del material. Finalmente, aunque el curso fue valorado generalmente de manera positiva, también hubo algunas desventajas: la falta de un curso de inducción en línea donde se planteara cada punto a trabajar, las escasas actividades que promuevan el trabajo colaborativo y en especial los desfases que se presentaban en algunos módulos, ya que el tiempo otorgado para la realización de cada una de las actividades en ocasiones o era demasiado o era muy recortado para su entrega. Estas observaciones realizadas por los participantes invitan a reflexionar sobre la necesidad de planificar más adecuadamente los elementos pedagógicos.
ACCESO A LA LENGUA ESPAÑOLA EN LA ESCUELA BRASILEÑA: BASES PARA EL FORTALECIMIENTO DEL PLURILINGÜISMO
Authors: Carvalho Tatiana Lourenço de
Published: June 2022

La enseñanza de español viene siendo marcada por diferentes movimientos de inclusión y exclusión en las instituciones educacionales brasileñas a más de un siglo. La aprobación de la Ley 11.161/05, la llamada “Ley del Español”, seguida de su derogación con la Ley 13.415/17, que pasa a ofrecer solamente el inglés como posibilidad de aprendizaje de un idioma extranjero en las escuelas brasileñas, es ejemplo de esto. Teniendo en cuenta este revés educativo, traemos en este artículo una revisión crítica de base documental acerca de la enseñanza de español, sobre todo considerando lo que concierne al plurilingüismo en estos documentos.

This paper presents a study of a single-phase cascaded H-bridge multilevel converter-based Distribution Static Synchronous Compensator (D-STATCOM) with active harmonic filtering capability. For the proper operation of the proposed D-STATCOM, a constant voltage is maintained at its DC bus link using a proportional and integral (PI) controller. Based on instantaneous current errors, gate pulses for controlling duty cycles of the D-STATCOM operation are generated using the hysteresis current control (HCC) technique. The proposed D-STATCOM was modeled and simulated in MATLAB. Simulation results show that the proposed method effectively compensates for reactive power and mitigates current harmonics. The proposed method offers structural simplicity and efficiency without complex calculations.

Published: June 2022

La disfagia es la dificultad para transportar un bolo alimenticio de forma segura y efectiva desde la boca hasta el estómago. Los métodos de diagnóstico de la disfagia son invasivos y altamente dependientes de la experiencia del personal asistencial. El estudio de bioseñales, como los registros de voz, se ha propuesto con el fin de desarrollar herramientas complementarias al diagnóstico. El presente trabajo explora características extraídas de señales de habla en un grupo de 30 personas sanas y 45 pacientes con disfagia diagnosticada. Los registros de los pacientes se dividieron en voz húmeda, voz disfónica y sin alteración. Se evaluaron espacios de características clásicas del análisis de voz mediante pruebas estadísticas y se encontró que las características asociadas a fonación, prosodia y diadococinesia son potenciales biomarcadores para la evaluación de pacientes con voz disfónica y voz húmeda en presencia de disfagia. Este trabajo constituye una aproximación preliminar basada en señales de voz para el diagnóstico no invasivo y objetivo de la disfagia.
Monetary policy and long-run share price reversals on the Johannesburg Securities Exchange
Authors:   Department of Business Finance, University of Witwatersrand, South Africa, Ayaya Rollins NG , Lin Runxin ,   Department of Business Finance, University of Witwatersrand, South Africa, Ayaya Onesmus ,   School of Accountancy, University of Limpopo, South Africa
Published: June 2022

Purpose: The study expounds on the phenomenon of long-run reversal and monetary policy in the financial markets. The study used Johannesburg Securities Exchange (JSE) data to determine whether the monetary policy changes implemented by the South African Reserve Bank impact long-run reversals in the JSE. Context: Long-run share value reversals have occurred in various regional financial markets in the US, Europe, Asia, and South Africa. Long-run share value reversals occur when firms with poor past performance rebound and produce superior returns compared to firms with good historical past performance. South Africa has a monetary policy of inflation targeting, leading to upward lending rate adjustments whenever consumer inflation threatens to exceed 6%. Methods: The regressions of the Fama-French three factors model and Fama-MacBeth model were used to estimate the relationship between the excess return of different portfolio returns and the Fama-French three factors. Furthermore, we split our sample under expansive and restrictive monetary conditions. We ran the regression of the Fama-MacBeth model again to see whether the monetary conditions will influence the long-run share price reversal. Results: The sample results over the near 15-year sample period showed that firms with poor past performance failed to outperform those with past solid performance. The gap is closed under restrictive monetary conditions that tighten the liquidity conditions of an economy. In addition, monetary policy changes led to long-run reversals among poor performing firms. Practical value: The study contributes to momentum theory. It is recommended that further research do a detailed examination of the relationship between firm characteristics and long-run reversals under various monetary conditions. Monetary conditions are worth watching for when constituting a portfolio because they create arbitrage opportunities for astute investors.
The Sundarbans: Sustainable tourism, livelihoods and economies involving Bangladesh and India
Authors:   Bucks New University, UK, Das Sarat Chandra
Published: June 2022

The Sundarbans, considered as the tourism heartland of South Asia and compared to Amazon rainforest for its expanse and biodiversity of flora and fauna spanning over 36,000 square kilometers, is currently at risk of massive depletion. The disaster can be avoided through sustainable tourism that minimizes negative social or environmental impacts and conserve fragile ecosystem consisting of flora and fauna and their habitats. This sustainable tourism can draw upon its basic tenets from the ‘’Sustainable Development Goals’’ propagated by World Tourism Organization. For both Bangladesh and India, it is obligatory under the remit of sustainable tourism to shift policy focus from growth to equity, thus, paving the way for strong institutions capability of regulating the tourism industry and distributing assets to facilitate ‘pro-poor growth’ policies and actions. As the current sustainable tourism debate is patchy, disjointed and often flawed with false assumptions and arguments the discourse on sustainable tourism of the Sundarbans needs to be oriented towards a thoroughbred scientific level, a systemic perspective and an interdisciplinary approach.

Data were collected and analyzed utilizing walkthroughs, questionnaires, interviews, and document review. Results indicate that the flipbook demonstrates the stages of flipped learning from out-of-class activities (independent learning experience at home, do assignments, and takes notes of less understandable) to in-class activities (deepening understanding of statistics through class discussions and working on problem-solving tasks). The flipbook developed meets the criteria of validity in terms of content and construct and ease of use. In addition, it has the potential effect to develop students' numeracy based on the document analysis of student responses regarding the process of formulating problems mathematically, employing formal mathematical structure, and interpreting solutions on a set of numeracy tasks.

The questions asked by the teacher affect students' thinking processes. So, it is necessary to do research that aims to describe what types of questions can provoke students to behave critically. The research subjects were 40 junior high school students around a coffee plantation in Jember, Indonesia. The data collection methods in this study were (1) test, (2) observation, and (3) interview. Each test was given two questions that meet the criteria for critical thinking behavior with the theme of coffee. The test is given at the end of mathematics lessons every Monday. Observations focused on three critical thinking behaviors, namely truth-seeking, open-mindedness, and inquisitiveness. Interviews were conducted at the end of the activity, namely after five learning meetings.  There are two findings in this research. First, junior high school students around coffee plantations are accustomed to truth-seeking, open-mindedness, and inquisitiveness in responding to questions from teachers. The habit of students in responding to teacher questions begins at the third meeting in learning. Second, there are three types of questions that can provoke students to behave critically. The three types of questions are questions that require students to construct concepts, principles, and procedures.Soal-soal yang diberikan oleh guru selama pembelajaran di kelas mempengaruhi proses berpikir siswa.

Solving mathematical problems require knowledge and experiences to determine the right strategy. One of the efforts that can be used to encourage problem-solving skills is to develop reflective thinking. Reflective thinking can be a strategy to explore mathematical problem-solving abilities by questioning the answers or questioning the problems encountered so that new thoughts can be used to determine appropriate problem-solving strategies. Therefore, this study aims to explain the reflective thinking process carried out by prospective teachers in solving mathematical problems. This study used a qualitative research design with data collection through test and interview process as a triangulation stage. Participants in this study were 2 prospective teachers who carried out a reflective thinking process and were known through think aloud in implementing the test. The results showed that scaffolding was needed to complete the reflective thinking process in problem-solving. Two scaffolding positions appeared in the reflective thinking stage: (1) after the questioning and evaluating stages, scaffolding is needed as a bridge to the reasoning stage; (2) After the questioning stage, scaffolding is needed to bridge the evaluating and reasoning stages. In the reflective thinking process, scaffolding generates new knowledge to find the right problem-solving strategy.
De la comunicación a la propaganda en la agitación política de la modernidad: legado para el mundo contemporáneo
Authors: Fernández García Eduardo
Published: June 2022

Las enseñanzas históricas sobre los detonantes de la acción política demuestran que la movilización requiere apoyarse en potentes canales comunicativos de legitimación. No es un fenómeno de la contemporaneidad, sino una constante verificable desde las contiendas dialécticas del mundo clásico. En el caso español, la apertura de cauces para la participación que abrió la Modernidad alcanzó también al lenguaje político, con una semántica moralizada de la política que aunaba discurso virtuoso del gobierno y relato dinástico. Lo hizo tanto para la aculturación en la ideología regia como para la justificación de la resistencia a ella, desde la publicística y hasta la insurrección armada. Este artículo postula, desde una mirada interdisciplinar, la conveniencia de elevar al primer plano de análisis los componentes comunicativos del mensaje político que se asentaron con el surgimiento del Estado moderno; no sólo como precursores de la propaganda, sino como constituyentes discursivos de la llamada al cambio en distintos momentos históricos a lo largo del siglo XX. La cultura política española no podría comprenderse adecuadamente sin este elemento duradero que la Edad Moderna legó a la contemporánea para rescatar la política de la retórica y entregársela a la pragmática.

Currently the division of matrimonial property after death of spouse is proportionated according to spouse’s contribution in acquiring the property. The share of deceased then be distributed to deceased heirs according to the legal portion provided by faraid law. This practice apparently could affect the interest of deceased spouse in the circumstance where the property of the spouse is only one asset particularly matrimonial home. The wife might lose the ownership of the home which resulted to the deceased wife lose her home to live. Moreover, the existing methods of distributions seem rigid and might take longer period to be settled. Thus, this study aims to examine the position of joint tenancy as a distribution of sole matrimonial property after spouse death from Shariah perspective and its practices in Malaysia. The study adopts qualitative methods where the data is collected from library resources including fiqh books, legal provisions and reported cases. The data was analysed using content analysis methods. The finding showed that joint tenancy is one of the instruments of estate planning for Muslims objectively to safeguard the interests of deceased spouse after the death of the spouse. The process of ownership and transfer of property will be implemented through the right of survivorship principle as well as facilitate the process of claims in shariah courts. It seems in line with the principles of maqasid syariah which prioritizes the maslahah of couples and children as well as avoiding disputes on the property between the deceased's heirs and the surviving co-owners.
