The purpose of this paper is to investigate ethical implications of surveillance by means of the care software “I‐Care” in the Swedish home‐help service sector.

A small‐scale interview study on home helpers' experiences of and reactions to the implementation of the care software “I‐Care” in their workspace has been conducted. The interview serves as the starting point for an ethical analysis of the impact of the care software “I‐Care” on key values within ethics: privacy, autonomy and equality.

The implementation and use case of surveillance capable technology in a home‐help service sector is assessed from the perspective of ethics. It is concluded that employees' level of awareness, access to sufficient and relevant information, as well as their chances of influencing surveillance conduct, are significant for their acceptance of the surveillance regime.

Surveillance in the home‐help service setting has been investigated from the perspective of ethnology and organizational studies but not, as here, from the perspective of ethics. Conditions for the ethical acceptance of workspace surveillance are suggested.

This paper aims to deal with an increasing securitization and criminalisation of migration in Europe highlighting ethical implications of the current surveillance-based EU migration governance. It is shown that EU member states employ surveillance regimes to control movements across borders and to restrict migrants' access to their territories. The ethical acceptability of such practices is questioned with a particular focus on the “freedom of movement”.

In order to establish the extent to which the current EU migration governance can be considered ethically justifiable, the article starts out from the right to mobility as coded in the UN Declaration of Human Rights. It is shown that the current migration governance obstructs the rights specified in Articles 13 and 14. At the same time, shortcomings of the UN declaration are discussed and the need for a better protection of the freedom of movement is suggested.

It is established that human rights are such that promote normative agency and a type of rights that trump, for example, states interests in restricting access to their territories do not outweigh individuals rights to seek asylum. In order to make this relation more clear however, the right to mobility should be made symmetric, including both a right to leave and to enter (but not a right to immigrate and settle). An extensive right to freedom of movement is advocated based on the significance of mobility for normative agency. A substantial right to mobility supports the right to seek asylum.

As of yet, ethical implications of surveillance-based border control are under-researched.

The purpose of this study was to investigate the efficiency of low temperature fractional crystallization to increase polyunsaturated fatty acid (PUFA) content of fish oil. Effects of temperature, stages of crystallization, rate of cooling, agitation and addition of primary nucleus on separation efficiency were evaluated. Low temperature crystallization of triacylglycerols (TAGs) was used to increase PUFA content of fish oil (initial PUFA content ∼30 g/100 g oil).

To optimize the fractionation process, the effect of fractionation temperature (7, 5, 0 and −5°C), crystallization procedures, cooling rate, agitation and addition of primary nucleus on PUFA content was evaluated.

The best relationship between PUFA concentration (45.8 g/100 g oil) and PUFA yield (51.5 per cent) was attained by performing two-stage crystallization of TAGs at the final temperatures of 5 and 0°C under slow cooling rate (3°C h−1 for first fractionation procedure and 0.7°C h−1 for second stage, until the final fractionation temperature, 0°C, was reached) and slow agitation (3 rpm) and in the presence of primary nucleus, which resulted in 50 per cent increase in PUFA content over the original fish oil.

Determination of iodine and saponification values, refractive index, solid fat content, melting point, cholesterol content of original oil and final fractionated product with the highest PUFA ratio showed that fractionation significantly alters physical and chemical properties of the fraction.

Comparison of iodine value, saponification value, refractive index, solid fat content, melting point and cholesterol content of original oil and the final fractionated product (with the highest PUFA ratio) showed that the fractionation process significantly alters mentioned properties of the initial oil.
