This paper aims to explore the relationship between gender occupational intensity and wages in the Northern Triangle of Central America using national surveys carried out in 2014.

A harmonized occupational classification at the -digit level is built with the objective of analyzing the occupational distribution across countries. Then, quantile regressions (QRs) are estimated to explore in detail which factors are affecting the wages of both females and males; in particular, this paper pays special attention to female occupational intensity (the share of females within each occupation).

The comparative analysis suggests that women are overrepresented in certain occupations, and they are much more likely to be working in part-time jobs than men in all countries. Furthermore, findings reveal that working in female-dominated occupations has a negative effect on wages along the distribution across countries. However, the effect of this variable is higher at the lower quantile of the distribution for women, especially in El Salvador and Honduras.

This paper first proposes a new typology of occupations, which allows a consistent and comparable analysis of the occupational structure. The results then provide a picture to address gender occupational intensity and its links with wages. Further, the characteristics of the labor market and differences in trends across these countries suggest that this topic requires challenging research for the region.

The purpose of this paper is to suggest the application of systemic methodologies, such as Soft Systems Methodology (SSM), to develop sustainability strategies and solve problems involving the sustainability of organizations and their operations. The sustainability paradigm implies the need for changes in current production systems, societal organization and use of the natural resources that are essential to all life forms. Sustainability, as a new paradigm, modifies the way in which organizations operate to make companies responsible for sustainable development and ensure that resources are available for future generations. Sustainable development requires a broad new development strategy that encompasses political, economic, social, technological and environmental dimensions.

As a method of analysis the research will use the application of SSM in a case study from the sugarcane industry. The basic scientific thought paradigm, inherited from Bacon and Descartes, no longer holds in modern society, which requires a new way of perceiving the world by following a systemic and integrated approach to address complex problems.

This study advances the understanding of how the systemic approach can aid the development of corporate sustainability strategies.

The basic pillar of the new sustainability paradigm is the systemic view. The systemic approach should guide the development of corporate strategies. This study followed a qualitative approach to better understand how organizations can use the systemic approach in the development of sustainability strategies.

This work focused on the sulphonation modification research of highly crosslinking non-polarity macroporous adsorption resin (MAR) LX1180; the adsorption behaviour of LX1180 and its chloromethylation- and sulphonation-modified products (LX1180-Cl and LX1180-SO₃₋); and the influence of the structure parameters matching degree of MAR and flavonoids on the adsorption feature and adsorption kinetics.

LX1180-SO₃₋ was obtained by the processes of chloromethylation first and then sulphonation. LX1180-Cl and LX1180-SO₃₋ were prepared through the principle of substitution reaction from LX1180 and LX1180-Cl, respectively. First, Monochloromethyl ether (ME), pre-treated ZnCl₂, NaCl and iron powder were added into the swollen LX1180 to obtain the chloromethylated LX1180. Thereafter, NaCl, NaOH and SAA were added into the swollen LX1180-Cl to obtain the sulphonation modification LX1180. The conditions were investigated and optimised; the structures of LX1180-Cl and LX1180-SO₃₋ were characterised by Fourier transform infrared chromatography (FTIR) and a specific surface area instrument. Finally, the adsorption kinetics and adsorption isotherm were used to evaluate the adsorption capacity of LX1180-Cl and LX1180-SO₃₋ for flavonoids, and the adsorptions and desorptions of LX1180-SO₃₋ with different sulphonation degree on different flavonoids were investigated systemically.

Results showed that LX1180-Cl and LX1180-SO₃₋ had been prepared successfully, and that after the sulphonation, the adsorption capacity tended to increase with the increase of adsorption time, and the equilibrium adsorption capacity of LX1180-SO₃₋ was also higher than that of LX1180.

The research only investigated the adsorption and desorption properties for only one kind of functional group, and other functional groups should also be studied in future work.

This contribution can provide a further base for the research of separation and purification of natural products with the aim to improve food additive removal or isolation and purification of flavonoids used for healthcare applications.

The adsorptions and desorptions of LX1180-SO₃₋ with different sulphonation degree on different flavonoids were investigated. The relationship between sulphonation degree and the adsorption and desorption capacities of flavonoids were also explored, and the results showed that with the increase of sulphonation degree, the adsorption of LX1180-SO₃₋ to rutin and cyanidin was maximum, while the desorption ratio was minimum at the same sulphonation degree; this phenomenon could be ascribed to the variation in the polarity matching degree.

This study investigates which dimensions of the management control system (MCS) increase the perception of organizational justice and reduce unethical behavior in the perception of managers. The purpose of this paper is to validate the theoretical model of the study of Langevin and Mendoza (2012), testing the theoretical hypotheses formulated by the authors.

A survey was performed in companies listed among the Best and Largest of Exame Magazine, and the sample is composed of 102 respondents of the research, which consists of 41 assertions.

The results of the structural equation modeling show that the definition of objectives increases the perception of procedural justice, but the same was not observed regarding the remuneration of the managers. Likewise, disregarding aspects that are uncontrollable by managers in performance evaluation does not lead to the perception of procedural and distributive justice. However, feedback quality leads to the understanding that the MCS is fair. Perception of procedural and distributive justice was also observed in the use of multiple measures of performance by the company.

Other factors that have not been investigated may interfere with and contribute to the reduction of unethical behavior (budget slack and data manipulation).

The only variable that interferes in the reduction of unethical behavior is feedback quality. The non-confirmation of all the hypotheses instigates the replication of the research in other contexts for empirical validation of the theoretical model of Langevin and Mendoza (2012).
