A caracterização do solo desempenha um papel importante no conhecimento de suas propriedades, como, por exemplo, os índices que demonstram o seu comportamento na presença de água ou a resistência quando são submetidos a esforços. A presença de solos adversos ao uso em pavimentação e o avanço da engenharia de rodovias direcionam os estudos geotécnicos para a busca de conhecimento que propicie o melhoramento dos índices das amostras de solo, a fim de torná-las aceitáveis para o uso. A amostra de solo utilizada no presente estudo foi coletada às margens do Rio Itapocu, no município de Jaraguá do Sul, região norte do estado de Santa Catarina, Brasil. Foram preparados corpos de prova estabilizados com cal e com adição de cimento, sendo para os dois métodos de estabilização o agente estabilizador adicionado em substituição de material nas porcentagens de 4% e 7%. A substituição do solo (argila siltosa) por estabilizantes mostrou resultados mais satisfatórios quando utilizada a porcentagem de 7% em vez de 4%, tanto para estabilização com cal quanto com cimento. O cimento apresentou um ganho de resistência de 259% e 244% em relação à cal, para 4% e 7% respectivamente, mesmo com um tempo de cura menor, sendo de 7 dias para o cimento e 14 dias para a cal.

Published: January 2024

A field experiment was conducted under irrigated condition to study the effect of planting geometry and intercropping on growth characters, leaf yield and quality in newly evolved, triploid, high yielding, recommended and popular S 1635 mulberry (Morus alba L.) along with intercrop yield and additional net profit. The plants were established through saplings in seven different spacing with variable number of plants / ha and were maintained through recommended package of practices for irrigated garden. Four different suitable intercrops, one in each season and one green manure crop in July September were taken up annually in mulberry for judicious utilization of space, time, nutrients and also for soil enrichment.
Significant differences were observed among the treatments in all the parameters studied. Growth attributes and leaf quality were improved along with soil nutrient status in paired row system, particularly in (90cm + 120cm) × 60cm spacing. Besides, it registered almost similar leaf yield (29 488.98kg/ha/year) compared to 60cm × 60cm spacing (control) in spite of 42.9% less plant population (15 873/ha) over control (27 777/ha), higher leaf yield / plant (0.37kg) and optimum intercrop yield as well as additional net profit of r35 368/ha/year (r5974.00 more over control).
Hence, this paired row spacing [(90cm + 120cm) × 60cm] may be useful and recommended to the farmers for mass practice in the cultivation of S 1635 mulberry with four intercrops and one green manure crop / year at least up to three years which did not adversely affect mulberry under irrigated condition. In addition, there is also a scope for partial mechanization which enables to reduce manpower requirement as well as economy in cultivation.

Métaphore et universaux grammaticaux et sémantiques : vers une représentation substantielle de la langue
Authors: Zaghouani Afifa 
Published: January 2024

Cet article traite la problématique des « universaux langagiers » à travers la question de la métaphore qui est une figure de discours partagée par plusieurs langues naturelles. L’enjeu de cette réflexion est de montrer comment ces universaux participent à repenser les faits de paroles en lien avec les faits de pensée. La métaphore développe deux types d’universaux : grammaticaux (liés à la prédication et à la modalisation) et sémantiques (relatifs à la signification et à la référenciation) lesquels contribuent à édifier une conception substantielle de la langue qui prouve que la substance n’est pas extralinguistique ; elle devient plus importante que la forme quand il s’agit d’appréhender le langage dans sa réalisation figurale.
Task-Related Leadership Competencies and Physical Work Environment as Predictors of Organizational Effectiveness in The Cameroon Baptist Convention Primary Schools
Authors: Godlove Ngalla , Kongnyuy Patrick 
Published: January 2024

Aim: The research addresses two primary objectives: examining the impact of headteachers' task-related leadership competencies (TR_competencies) and work environment (WE_index) on organizational effectiveness in terms of stakeholder involvement (SI_OE).
Methods: This study employs ordinary least squares (OLS) regression analysis to scrutinize the predictive efficacy of leadership competence and conditions of service on organizational effectiveness in Cameroon Baptist Convention (CBC) primary schools.
Results: Statistically significant relationships are identified. Regression coefficients underscore the robustness of CBC headteachers' task-related leadership competencies, encompassing accountability, creativity, diversity promotion, culture shaping, and strategic planning. Challenges in change management highlight areas necessitating targeted professional development. A negative coefficient for the work environment implies an inverse relationship with organizational effectiveness in terms of stakeholder involvement. The F-statistic tests the overall model significance, yielding p-values of 0.0001 and 0.0000 for Models 1 and 2, respectively.
Conclusion: These results prompt rejection of the null hypothesis, confirming the overall model significance. Furthermore, the coefficients for TR_competencies and WE_index are statistically significant at the 0.01 level, affirming their individual impact.
Recommendations: This study recommends that the CBC Education Department should engage comprehensive strategy to bring about organisational effectiveness in the primary schools. That strategy should involve targeted professional development for headteachers on key leadership competencies, simultaneous improvements in the physical work environment, and stronger stakeholder engagement strategies. Policymakers are equally encouraged to translate these findings into actionable policies. This should organisational effectiveness in the CBC Primary schools.
