Authors: Rizki Wahyu Mutia , Dewanti-Hariyadi Ratih , Kusumaningrum Harsi Dewantari
Published: March 2023

This study aimed to develop and compare growth models of Bacillus cereus in cooked and fried rice. A cocktail of B. cereus was inoculated into cooked and fried rice to obtain an initial concentration of ca. 2 log CFU g-1 and stored at 13, 30, 42, and 60oC. The cell concentration of B. cereus during storage were fitted to the primary models of Baranyi, Huang, and modified Gompertz. The maximum specific growth rates (µmax) were fitted to the Ratkowsky model, while the lag phase was fitted using the first-order polynomial model. There was no significant difference (p>0.05) in the µmax and lag phase of B. cereus in cooked rice or fried rice at 13 and 30oC. However, at 42oC the µmax in fried rice was significantly higher (p<0.05) and the lag phase was significantly longer (p<0.05) than those in cooked rice. No growth was observed at 60oC. The Baranyi model showed the best performance in fitting the µmax of B. cereus in cooked and fried rice. The validation study confirmed that the Ratkowsky and the first-order polynomial model could satisfactorily fit the µmax and the lag phase, respectively.  Modeling of B. cereus growth in cooked and fried rice can use the primary model of Baranyi fitted to the secondary model of Ratkowsky and first-order polynomial to predict the growth rate and lag phase, respectively. The model suggests that B. cereus grows significantly faster in fried rice at 42oC.
Cuentapropismo juvenil en el Gran Resistencia (Chaco).
Authors: Barbetti Pablo , Sobol Blanca
Published: March 2023

El artículo propone una caracterización del cuentapropismo de jóvenes que residen en el aglomerado urbano Gran Resistencia (provincia del Chaco), mostrando algunas variaciones en este grupo en dos contextos temporales (prepandemia/pandemia) y comparando las mismas con algunas tendencias a nivel nacional y en la región NEA (nordeste argentino).

Se parte de un diseño metodológico cuantitativo, recurriendo al procesamiento estadístico descriptivo, utilizando como fuente las bases de microdatos individuales de la Encuesta Permanente de Hogares (EPH) perteneciente al Instituto Nacional de Estadística y Censos de la República Argentina (INDEC). Los resultados obtenidos muestran que el cuentapropismo juvenil en el territorio analizado se incrementó en el contexto de pandemia, especialmente en jóvenes de menor edad y nivel educativo. Si bien en este aglomerado urbano se observan tendencias y características similares de esta categoría ocupacional en la población total, el grupo de jóvenes se encuentran en una posición de mayor desventaja en términos de condiciones de trabajo.
¿Idealismo realista?
Authors: Dieguez Martin
Published: March 2023

El objetivo de este artículo es investigar la incidencia de los condicionantes internos y externos en la conformación y la ejecución de los principales lineamientos de la política exterior de la presidencia de Alberto Fernández. En el frente doméstico, se estudia el sistema de creencias del presidente, la dinámica coalicional y el delicado estado de la economía. En el frente externo, se examinan las situaciones disparadas por la pandemia COVID-19 y la guerra entre Rusia y Ucrania, así como también el giro ideológico de la región y Estados Unidos. Estos factores, combinados con un análisis de los principales espacios geográficos de la política exterior argentina más los temas de agenda centrales, permiten sistematizar ocho lineamientos seguidos por el gobierno. De ellos, se extraen una serie de hipótesis principales: los condicionantes ideacionales parecen tener un mayor impacto en la conformación de los lineamientos, mientras que el juego político local y los condicionantes externos parecen afectar más fuertemente a su ejecución.
Cooperación y dependencia en la relación bilateral de China y Argentina:
Authors: Treacy Mariano
Published: March 2023

La República Popular China es un socio estratégico integral de Argentina. El crecimiento de la importancia de las inversiones y préstamos chinos en Argentina y América Latina ha respondido a la estrategia de política exterior de China, que ha puesto en marcha numerosos programas para consolidar su liderazgo internacional en el contexto de una disputa con Estados Unidos. En febrero de 2022 la Argentina ingresa a la Iniciativa de la Franja y la Ruta (BRI). Si bien la firma del memorándum es aún demasiado reciente para evaluar su impacto, en este trabajo nos proponemos realizar un aporte a la comprensión de las razones económicas, políticas y geopolíticas que explican el ingreso a la BRI y los efectos que este hecho podría tener en el futuro de las relaciones bilaterales y en la estrategia de desarrollo de la Argentina. Para ello analizamos en primer lugar la estrategia de política exterior y la consolidación del liderazgo internacional de China en el marco del programa Go Out y del lanzamiento de la Iniciativa de la Franja y la Ruta, y presentamos su estrategia de política exterior específica para América Latina y para Argentina a través de un análisis de las inversiones directas y los préstamos de la banca estatal, principalmente el Eximbank y el China Development Bank (CDB).

Published: March 2023

Mexico is one of the main consumers of PET worldwide. In Mexico, urban solid waste has not received adequate attention due to a series of factors of various kinds, among which are: Collection of mixed garbage (in 95% of the national territory) [I, II], public services insufficient and inefficient cleanliness, poor coordination between the different levels of government, incomplete legal framework and legislative work with a particular vision, passivity in ecological matters and little culture of recycling in society [III, IV, V]. Sustainable development, as it is currently disseminated, begins in 1983, when the United Nations (UN) created the Commission on Environment and Development, chaired by Gro Harlem Brundtland, who was Prime Minister of Norway. The Brundtland Commission, carried out studies, analyses, and public consultations [VI], all over the world, for approximately three years, ending in April 1987, with the publication and dissemination of the report called Our Better Common Future known as The Brundtland Report [VII, VIII, IX]. The objective of this study was to determine the temperature at which polyethylene terephthalate (PET) in the form of granules, changes from amorphous to crystalline, since recrystallization improves the properties, which is necessary for the reuse of the material.
Oxidative stress in the central nervous system of iron-deficient females
Authors: VIEYRA-REYES Patricia , BLANCAS-CASTILLO Sergio E.
Published: March 2023

Iron deficiency is a worldwide public health problem associated with behavioral and cognitive disturbances. These disturbances are irreversible if not treated during the perinatal period. Iron is a structural part of several proteins, such as the antioxidant enzyme catalase. It has been shown that females are less susceptible to oxidative stress. However, the levels of oxidative stress at the central system in the presence of chronic iron deficiency or post-weaning supplementation are unknown. Objective: to determine the levels of oxidative stress and antioxidant defense in females with chronic iron deficiency, untreated or treated with iron supplementation. Methodology: female Wistar rats with chronic iron deficiency and rats supplemented from weaning to adulthood (70 postnatal days) were euthanized to analyze brain tissue and determine oxidative stress through lipid peroxidation; and antioxidant effect by superoxide dismutase, catalase and total proteins. Contribution: in the presence of chronic iron deficiency, lipid peroxidation levels at the central system are so high that they cannot be counteracted by superoxide dismutase or catalase. However, postnatal supplementation prevents lipid peroxidation from being altered due to the high production of iron-induced antioxidant defense.

Published: March 2023

Proposing animal models that allow predicting results in humans becomes critical when the analogies in physiology between both entities are reviewed. About heart disease, the heart rate in humans is more similar to that of chickens than that of the mouse, rat or other mammalian models generally used to study this disease. In the present work, the ethology on the attraction of chickens to earthworms as a food source was reviewed, in addition hematological, organ and urological parameters were measured in chickens fed with double and triple the protein percentage supplied with Eisenia foetida live added to the feed. commercial for the Cobb500 line. The results show a marked attraction depending on the nutritional status of the birds for Eisenia foetida and differences in hematological parameters, but not for urological parameters. The morphological characteristics of the heart showed a clear association between three times the protein load in the food and cardiac damage in 2 of 7 animals fed during 7 weeks of study. The present work represents the first contribution with the animal model approach in chickens to study cardiac damage and its possible prediction for humans.

The use of LED technology advances rapidly in different fields of agricultural sciences, among others to generate stimulating effects to the physiological development of exposed plants. The objective of the present study was to characterize the physiological response to photoperiod with LED light in corn plants. Four genotypes and four photoperiod treatments were evaluated with LED lighting (white, blue, green, red). The experimental design was randomly complete blocks with three repeats, the treatments were the combination of genotypes and light spectra. The response variables were: height, stem diameter, radicle length, radicle volume and leaf area. The data were analyzed by ANOVA, running a multiple comparison test of means by Tukey. The results showed similarity in the behavior of LED light in some variables, while in the genotypes there was a different interaction before each treatment. For physiological stimulation it was obtained that, blue LED improves root quality (absorbent capillaries and water storage content) in the B1G, RG and B2G genotypes, while the red LED in the WG, B1G and B2G genotypes and in the green LED the B1G, RG and B2G materials, stimulated the vegetative growth of stem in the seedling respectively.

Published: March 2023

Poor oral hygiene in adult patients, reported and analyzed in different studies that have been done worldwide, has generated a high rate of dental loss. Partial edentulism is defined as a state of oral health that is the cause of an adverse effect of the state of oral health that corresponds to the absence of a certain number of teeth in the mouth. Most of the population has an incomplete but functional dentition, there is another large population group that does not have prosthetic restorations, which are very necessary. The causes of partial edentulism can be congenital or acquired. Total congenital edentulism manifests as a very serious congenital syndrome, which, generally, are not compatible with the patient's life. On the other hand, acquired edentulism refers to dental loss during one’s life and can be of secondary causes such as caries or dental loss as mentioned, such is determining the prevalence of partial edentulism in patients of the Faculty of Dentistry at the Universidad Autónoma de Campeche with the Kennedy classification. The loss of dental pieces results in the alteration of the stomatognathic system, resulting in the alteration of the masticatory function, affecting the nutritional state, general health and quality of life. Several studies have affirmed that edentulism, in addition to being related to the patient’s nutritional state, is also associated with the following factors: quality of life, age, gender of the patient. An observational, descriptive cross-sectional study was carried out at the Universidad Autónoma de Campeche, in the clinics of the Faculty of Dentistry. The population for this study was 100 subjects. The total number of subjects studied was 100 subjects (n=100), 51% were male and 49% female, the mean age was 59 years with a standard deviation of 11 and a range of 53. Regarding the variable, educational stage, the majority only studied middle school followed by primary school. The distribution of the prevalence of partial edentulism with respect to sex, Kennedy class II reported prevalence in males with 21%. It is followed by class I in males with 10%, class III in third place but in females with 18% and finally class IV where females also prevail with 12%. This study shows that the most prevalent of evaluated patients was found to be Kennedy class II in the male sex, since it was the most representative of the population with 21%, while, on the part of the female patients, it was 18% in class III.

O presente estudo teve como objetivo traduzir para o português do Brasil e analisar a validade de conteúdo da Leisure Attitude Scale (LAS), propondo assim a versão brasileira do instrumento a Escala de Atitudes ao Lazer (EAL). Seguindo os critérios estabelecidos por Herdman, Fox-Rushby e Badia (1998) o método utilizado para a tradução e adaptação transcultural foi constituído pelas análises das equivalências conceitual, de itens, semântica, operacional e de mensuração. As etapas do processo foram: tradução e retrotradução, revisão técnica, avaliação da clareza da linguagem, pertinência prática e relevância teórica, aplicação dos instrumentos em grupo focal; reteste, e, por fim, a aplicação do instrumento finalizado em amostra de indivíduos adultos. Participaram do estudo adultos de ambos os sexos, trabalhadores do setor industriário da Grande Florianópolis – SC/Brasil. A amostra foi composta por 180 trabalhadores para análise da reprodutibilidade e 992 para os indicadores de consistência interna. Além disso, onze especialistas na área do lazer contribuíram para o processo de adaptação transcultural e validade de conteúdo do instrumento. Os especialistas atribuíram valores satisfatórios para a análise de conteúdo nos itens clareza e linguagem (CVCt = 0,818), pertinência prática (CVCt = 0,782) e relevância teórica (X = 3,91; DP = 0,83). Os índices de reprodutibilidade por meio da análise de correlação intraclasse em teste-reteste foram considerados adequados em todos os domínios da LAS (cognitivo = 0,785 - bom; emocional = 0,847 - ótimo; comportamental = 0,923 - excelente). Além disso, o Alpha de Cronbach apresentou valor de 0,958. Pode-se afirmar que a EAL se constitui em instrumento válido para a investigação das atitudes dos adultos face ao lazer nos domínios cognitivo, afetivo e comportamental, apresentando adequados indicadores psicométricos de validade, reprodutibilidade e consistência interna.

Published: March 2023

The objective of this study was to demonstrate the importance of chironomid (Diptera, Insecta) larvae as food resource for Leporinus amblyrhynchus Garavello & Britski, 1987 (Anostomidae, Characiformes) and Pimelodus maculatus Lacépède 1803 (Pimelodidae, Siluriformes) and to call attention for the importance of the trophic relation between fish and chironomids assemblages in Miranda reservoir in Araguari River (Minas Gerais State, Brazil), focusing on the influence of the dam on the structure and taxonomic composition of chironomid assemblage. A total of 318 stomach contents of L. amblyrhynchus and P. maculatus were checked of which 108 had chironomid larvae. The number of chironomid larvae observed in stomach contents was higher for L. amblyrhynchus (86.3%) than for P. maculatus (52.7%). The recorded taxonomic richness of chironomid larvae in the stomach contents, suggest that these two fish species invest considerable time and energy feeding on chironomid larvae, thus consisting an important food resource. The recorded data constitute important additional information on the biology of the two studied fish species.

A floristic survey of pteridophytes was carried out in two forest areas of Minas Gerais, Brazil: Estação Biológica de Caratinga (EBC), and Parque Estadual do Rio Doce (PERD). We identified 102 species, 43 genera, and 18 families for EBC and 123 species, 43 genera, and 19 families at PERD. Seventy five species were common to both areas, 27 were found, exclusively in EBC, and 40, in PERD. Families with highest number of species, in EBC, were Pteridaceae (15 species), Thelypteridaceae (11), Tectariaceae (10), Polypodiaceae (8), Aspleniaceae and Dennstaedtiaceae (7 each), Cyatheaceae and Schizaeaceae (6 each); and in PERD Pteridaceae (24 species), Thelypteridaceae (17), Polypodiaceae (11), Tectariaceae (10), Aspleniaceae (9), Schizaeaceae (8), and Aspleniaceae (7), Cyatheaceae and Woodsiaceae (6 each). Most of the species in both areas are terrestrial. Most of the species presented a wide geographical distribution in Brazil, with only 25% restricted to Southeastern Brazil. We presented the list of taxa of the two studied areas, data about species habit, and the geographical distribution of some species reported for the first time in Minas Gerais state and discuss about richness of these species.
Descrição da ninfa e redescrição dos adultos de Callibaetis radiatus Navás (Insecta: Ephemeroptera: Baetidae)

Published: March 2023

The nymph of Callibaetis radiatus Navás (Insecta: Ephemeroptera: Baetidae) is described for the first time based on reared specimens. The following characteristics distinguish the species in the nymphal stage: labium slightly excavated medially; lingua of hypopharynx with three apical lobes; left prostheca robust, apically bifurcate, outer branch robust and with setae on inner margin inner branch slender; femur pale white, with dark gray punctuations anteriorly; tarsal claws with two rows of slender denticles; and arrangement of posterior spines on terga and paraprocts. Male and female adults are redescribed and are distinguished from other adults of Callibaetis by the following combination of characteristics: forewing costal and subcostal area strongly pigmented in females and without pigmentation in males; marginal intercalary veins of forewing mostly single; hindwing transparent, relatively narrow, with apex of costal process truncate and cross veins thicker than longitudinal veins; abdominal color pattern; and first segment of male genital forceps with acute internal process and third segment truncate. The species is reported for the first time from Brazil, thus expanding considerably its known range to the north.
Convergent characteristics of begging vocalisations in Australian birds
Authors: Jurisevic Mark A.
Published: March 2023

The acoustic structure and sound pressure level (i.e. loudness) of begging calls from nestlings and fledglings were examined for 12 species of Australian passerines and three species of parrots. There was a great deal of variation in the acoustic structure of the begging calls between species. Some calls were quite short in duration (0.06-0.1 s) while others were very long (0.98-1.51 s). However, most begging calls were loud and covered a wide range of frequencies consisting of noisy and/or harmonic components. These acoustic characteristics, which were observed in all species, presumably allow for efficient detection and location of the calling bird by parents, as well as signalling the birds’ nutritional requirements. The potential negative consequences of producing these vocalisations are an increased risk of detection by predators and a high metabolic cost. The findings of this study suggest that the potential risks associated with begging in Australian birds are offset by the benefits gained from producing loud, wide band vocalisations that can be easily detected and located by parents.

Do peacocks devote maintenance time to their ornamental plumage? Time budgets of male blue peafowl Pavo cristatus
Authors: Walther Bruno A.
Published: March 2023

Elaborate secondary sexual traits, such as the ornamental plumage of birds, appear to be favoured by female choice because they serve as honest advertisements of male quality. Elaborate plumage is thought to be an honest signal because it is energetically expensive to produce and to carry, and it may also increase the vulnerability of males to predators. According to several recent studies, the elaborate ornamental train of male blue peafowls (Pavo cristatus) appears to be such an honest signal. In this paper, I explore another potential cost of such plumage, which is the daily time and energy investment required to maintain the plumage in good condition. Since time devoted to maintenance cannot be devoted to feeding, vigilance, or other activities, the maintenance cost of ornamental plumage should reinforce the honesty of such plumage as an advertisement of male quality. I observed free-ranging peacocks for 30 hours at the Denver Zoo in June 2002 and April 2003. Preening, scratching and dusting took up more than 99% of maintenance time. Long bouts of maintenance behaviour were performed while peacocks were resting or standing, while short bouts occurred while peacocks were walking or feeding. No maintenance behaviours were observed while peacocks displayed their trains. Peacocks spent 14.9% of their total time budget on maintenance behaviours and 7.2% on displaying their trains, and 25.2% of their total grooming time on preening their trains. Consequently, peacocks not only incur the costs of producing and carrying their trains, but they also pay an additional maintenance cost. Hypotheses concerning the indicator mechanism of ornamental plumage need to consider these additional costs, as any additional cost should make the signal even more “honest”.

Male euglossine bees were sampled with chemical attractants in September 2003 at five sites at Parque Estadual do Rio Preto, Minas Gerais state, Brazil. Two sites were located in typical "cerrado" area, two in gallery forests and one in "campo rupestre" formation. We collected 222 bees of ten species; Euglossa melanotricha was the most common at every site, followed by Euglossa fimbriata, and cineole was the most attractive bait. Comparisons with Atlantic Forest fragments suggest a relatively high diversity of orchid bees in the cerrado domain.

A study on the structure and distribution of Chironomidae fauna was carried out in a third order section of the Cascatinha River, Nova Friburgo, Rio de Janeiro, Brazil. The samples were taken out from four substrate types: litter from riffles, litter from pools, and sand and rock in erosional areas. A total of 4,973 larvae were collected, among which, those of Chironominae were the most abundant and diverse. The most abundant taxa were: Rheotanytarsus in the litter from riffles, Polypedilum in the litter from pools, Cryptochironomus in sand, and Cricotopus in rocks. The functional feeding groups predominant during the dry and rainy seasons were filtering-collectors and scrapers, respectively. In relation to substrate, the filtering-collectors were the most abundant in litter from riffles and rock, the gathering-collectors in litter from pools and the predators in sand. The shredders showed a low relative contribution in this study. The current flow, the nature of substrate and the food availability showed great influence on the distribution and structure of the chironomid community in the ecosystem.

Between August 1998 and August 1999, hummingbirds and plant species used by an them as nectar sources were recorded in the Mata do Paraíso forest reserve. This area is a regeneration of Atlantic Forest with an area of 194.36 ha. It is located in the municipality of Viçosa, in the Forest Zone of Minas Gerais. Fourteen plant species were visited by the hummingbirds as floral resources, 11 of them ornitophilous and three entomophilous. Most of the plant species occures in the understore or in the forest edges, presenting herbaceous or creeper habitus and bloom in during the rainy season. During the dry season, Geissomeria schottiana and Ruellia brevifolia seemed to be the main nectar sources for the hummingbirds. In five ornitophilous species of Acanthaceae, we recorded six of the eight hummingbird species, confirming the importance of this family for the maintenance of hummingbirds in the reserve. Phaethornis ruber was the most common hummingbird observed (it visited flowers of 10 species), followed by P. squalidus (nine species) and Thalurania glaucopis (four species). Males of T. glaucopis displayed territorial behavior when visiting flowers of G. schottiana and Mendoncia velloziana.
Quirópteros da Estação Ecológica da Serra das Araras, Mato Grosso, Brasil, com o primeiro registro de Artibeus gnomus e A. anderseni para o cerrado

Published: March 2023

We present the results of the first bat inventory at the ‘Serra das Araras’ Ecological Station, MT, in the northwestern portion of the Cerrado domain. We captured bats using the traditional ground-level mist netting and, occasionally, high nets placed 3 m above the ground, and hand nets for hoosting bats. We recorded 23 species distributed in six families (Emballonuridae, Noctilionidae, Mormoopidae, Phyllostomidae, Molossidae, and Vespertilionidae), including Artibeus gnomus and A. anderseni, which had never been recorded in the Cerrado domain.
Observações sobre aves granívoras (Columbidae e Emberizidae) associadas à frutificação de taquaras (Poaceae, Bambusoideae) na porção meridional da Cadeia do Espinhaço, Minas Gerais, Brasil

Published: March 2023

We present the results of observations on the birds associated to the seeding of two bamboo species in southern Espinhaço Range, Minas Gerais, Brazil. The sooty grassquit (Tiaris fuliginosa – Emberizidae) was recorded feeding on seeds of Parodiolyra micrantha (Kunth) Davidse & Zuloaga. Further, T. fuliginosa and the blue ground-dove (Claravis pretiosa – Columbidae) were recorded in another area, apparently associated with the seeding of P. micrantha. The uniform finch (Haplospiza unicolor – Emberizidae) was a common species in an area dominated by Chusquea attenuata (Döll) L. G. Clark. Although H. unicolor was not observed feeding on bamboo seeds, we presume that the concentration observed was due to the massive seeding of C. attenuata at Serra do Caraça, since it is not a common bird species in this area. Possibly, the absence of threatened and rare bird species previously recorded as associated to bamboo seeding is related to the fragmentation of forests and capture for illegal trade.
Ocorrência de Pseudomenopon pilosum (Scopoli, 1763) (Phthiraptera: Amblycera) no Brasil

P. pilosum is recorded for the first time in Brazil. This is a species of chewing louse that participates as an invertebrate host in the biological cycle of a bird filarid. The possibility for this transmission to be occurring in Brazil is discussed and the reports about the participation of these parasites as bioagents spreaders are summarized.
Zygosaccharomyces machadoi sp. n., a yeast species isolated from a nest of the stingless bee Tetragonisca angustula
Authors: Rosa Carlos A. , Lachance Marc-André
Published: March 2023

A new yeast species, Zygosaccharomyces machadoi, was discovered in garbage pellets of the stingless bee Tetragosnica angustula in Brazil. Analysis of the sequence of the D1/D2 domains of the large-subunit rDNA showed that the new species is related to Zygosaccharomyces rouxii. Z. machadoi probably causes food spoilage in hives of stingless bees. It assimilates only a few carbon sources such that it is difficult to distinguish it from other Zygosaccharomyces species based on conventional physiological tests. The type strain of Z. machadoi is UFMG-J01-63.2T (CBS10264T).

Published: March 2023

The paper explores the key factors relevant to the development of micro and small businesses in the Andaman and Nicobar Islands. This study specifically focused on the relevant factors from the islands' perspectives. This study used primary sources of data collected in the South Andaman Islands (Andaman and Nicobar Islands), and the obtained data were analyzed using SPSS. The findings of the study proved that tourism business and marine and wood-based businesses have huge potential in the Andaman Islands. The study's findings highlighted the significance of subsidies and incentives for island promotion and sustainable development, which could be accomplished through capital investment, as well as transportation subsidies, which are critical for new and existing businesses on islands. Cargo transportation from the mainland to islands is the primary mode of sea transportation and the only mode between island regions. Under this situation, the Andaman and Nicobar Islands totally rely on manufacturing or service businesses as a lifeline. Hence, micro- and small businesses will play a vital role in employment generation, production, investments, and the growth of a small business. As a result, the administration of the islands should implement appropriate policy measures based on the relevant factors in the islands' region. The local administration needs to support and provide easy access to finance, transportation, and other facilities for small businesses in the Andaman and Nicobar Islands.
L’evoluzione della percezione della mafia italiana e l’impatto di Saviano sulla stampa francese
Authors: Canto Anne-Sophie
Published: March 2023

The aim of this article is to show how the perception of the Italian mafia phenomenon, which was initially a paradox, has evolved over the last few years in France. Indeed, for a long time it seems to have been the object of a surprising paradox: while it was factually present on French territory, the press seemed to focus mainly on its role in Italy. However, in recent years, two events have gradually overturned this view: the attacks on the newspaper Charlie Hebdo in January 2015, and then the presence of Saviano who, as a literary and media figure, has liberated the word around the organisation and expansion of Italian organised crime.

إحدى المناقشات الهامة في الأوساط العلمية هي المناقشة التاريخية للأحاديث النبوية. يعتقد أتباع الأحاديث النبوية التاريخية أن الأحاديث النبوية تعتبر تاريخية ولا يمكن بأي حال من الأحوال أن تنتقل إلى أوقات أخرى. موضحا أن الأحاديث النبوية هي نتاج الثقافي وتحديدا في حقبة تاريخية ولا يمكن أن تكون نصا مرجعيا في أوقات لاحقة. الأحاديث النبوية لها تأثيرات مختلفة في مجتمعات اليوم. وقد ورد ذكر بعض هذه الأحاديث في كلام الإمام علي () وتعامل مع هذه الأعمال في خطبه. ولكن إلى جانب كلمات الإمام علي () ، يمكن تقديم أعمال الحديث النبوية المختلفة ، مثل أعمال الأحاديث المتعلقة بمؤسسة الأسرة. الأسرة مؤسسة لا يمكن أن تكون مؤسسة أكثر احترامًا أمام الله ، فهذه المؤسسة تحتاج إلى قوانين وأنظمة خاصة لتكون قوية و مستمرة قدر الإمكان. الزواج هو النواة الأساسية لأي مجتمع ، وهو يعني بقاء الجنس البشري خلال العلاقات المقدسة. للعقد النكاح أهمية خاصة ومكانة في الشريعة الإسلامية ، لدرجة أن الله يذكر هذا العقد كالمبثاق الغليظ. في هذا الصدد ، أدخلت الأحاديث النبوية أعمالًا مختلفة مثل تشجيع الزواج ، وتقديم مبادئ تربية الأطفال ، وما إلى ذلك فيما يتعلق بهذه المؤسسة
The Impact of Performance Management on Employee Performance
Authors: Almulaiki Waleed Ameen
Published: March 2023

In order to discuss the most significant findings of those studies in four main axes—the impact of PMS on employee performance, the components of the PMS, and the literature review—this paper reviews the literature on the impact of performance management practices on employee performance during the period (2015–2020). Additionally, the traits of a successful PMS and the challenges faced when implementing the system. The article came to the conclusion that the performance system has a significant moral impact on how well workers perform in firms. These studies provided conclusive evidence that, in addition to the PMS, working conditions, compensation, and promotion are organizational elements that influence employees' performance. Performance monitoring is carried out with performance assessment by management since, according to the research; performance planning has a limited impact on workers' performance while performance appraisal has been the most precise of employee performance.
