Rainfall erosivity, soil erodibility and natural water erosion potential in the Huambo region, Angola
(2021-12-06)
The use of erosion assessment methods is critical for the sustainability of land use in tropical and subtropical regions, especially in countries lacking national information on soil erosion development, which is the case of Angola. This study aimed to evaluate the rainfall erosivity (R), soil erodibility (K), soil loss tolerance (T) and natural erosion potential (NEP) in Huambo (Angola). The R value estimated for a 25-year period was 7463 MJ·mm·ha-¹·h-¹·y-¹. K values estimated from 25 soil profiles, described in the ...

The role of crop protection products of multinational brands for agricultural sustainability in the cotton-growing zone in Pakistan
(2022-01-22)
Despite the use of Bt (Bacillus thuringiensis) cotton in Pakistan, the country is still far behind in farm harvest per unit compared to other cotton-producing countries such as China and Turkey. Cotton is a pest-sensitive crop, and inappropriate crop protection products contribute to lower agricultural sustainability. This issue attracts additional attention in developing countries such as Pakistan, where generic formulation/sub-standard crop protection products are easily and abundantly available. However, the impact ...

Eugenio Coseriu and pragmatics
(Walter de Gruyter, 2021-09-07)
Eugenio Coseriu’s linguistic thinking is essentially based on the concept of speaking as activity. This understanding is absolutely central to Coseriu’s system of linguistic competence, whose core are the rules and traditions that govern language use. Pragmatics is thus not a discipline focused on the analysis of specific linguistic structures of the language system (langue), but rather a perspective on language (Verschueren 1995: 11, 2009: 14–16) that explores its use and its potential in speaking as an activity ...

Significado y efectos de sentido. El gérondif francés en el contexto románico
(2021)
En las lenguas románicas una función central de los gerundios consiste en crear vínculos o junciones (Raible 1992) entre acciones diversas en el marco oracional. El concepto de junción implica que dos acciones –la actividad expresada por el gerundio y la actividad de la oración matriz– se agrupan para formar una unidad estructurada. El punto de partida de nuestro estudio es el análisis del gérondif en francés, cuyo perfil semántico-pragmático se elabora en primer lugar y constituye la base de un estudio contrastivo ...

Determinants of Willingness to Pay (WTP) for organic fertiliser: a case of smallholder potato farmers in KwaZulu-Natal, South Africa
(2021-12-01)
The South African smallholder sector is characterised by relatively low productivity due to persistent deterioration in soil fertility owing to declining organic matter and other essential soil nutrients. Consequently, adoption of sustainable agricultural inputs like organic fertiliser is essential. Although there is sufficient advocacy in the adoption of organic fertiliser, the economic linkage between farmers' socioeconomic factors and willingness to pay (WTP) remains under-explored. This study investigated the ...

Profiling Tunisian olive oil Consumers based on the Environmental Sustainability value perception
(2022-04-15)
Most of the research works about consumer behavior toward olive oil are based on quality attributes and indicators. Consumption values have not been explored, especially for olive oil consumption. Thus, the present work proposes an analysis of the Tunisian consumer’s behavior towards olive oil, based on consumption values, especially environmental sustainability value since olive oil is typically a green and sustainable product. Drawing on the findings of a survey of a Tunisian household’s sample, an exploratory ...

Drivers of adaptation to climate change in vulnerable farming communities: a micro analysis of rice farmers in Ndop, Cameroon
(2021-11-04)
Farmers in developing economies often struggle to adapt to climate change and their decisions to adapt usually hinges on perception and prevailing socio-economic factors. This study examines factors controlling farmers’ decision to adapt to climate change and evaluate the impact of such decisions on farm output. Using primary data from 138 rice farming households in Ndop-Cameroon, we employ the probit model with endogenous switching regression to investigate the impact of the farmers’ adaptation decisions on output. ...

Influence of Microstructure and Defects on Mechanical Properties of AISI H13 Manufactured by Electron Beam Powder Bed Fusion
(2021-08-04)
Electron beam powder bed fusion (E-PBF) is a well-known additive manufacturing process. Components are realized based on layer-by-layer melting of metal powder. Due to the high degree of design freedom, additive manufacturing came into focus of tooling industry, especially for tools with sophisticated internal cooling channels. The present work focuses on the relationships between processing, microstructure evolution, chemical composition and mechanical properties of a high alloyed tool steel AISI H13 (1.2344, ...

Is the Mafia a State Apparatus?
(2021-12)
Starting from the relations of production, this paper examines the role of mafia for the preservation of social power and class relations in Sicily. To this end, the concept of the informal state apparatus is introduced. Following the approach of Critical Grounded Theory, this paper proposes to fill explanatory gaps in conventional mafia research by means of Nicos Poulantzas’ historical materialist state theory. In-depth field research confirms the systematic generation of irregularity through conditions in which it ...
