RESUMEN
BACKGROUND: It can be challenging for support staff to develop meaningful moments of interaction with people with profound intellectual disabilities. Gathering information on observable behaviour characterising such meaningful moments is expected to be beneficial. METHOD: Three staff-client dyadic interactions were videotaped for 30 min. During reviewing the recording, staff members indicated which moments of interaction they experienced as meaningful. Per dyad, one meaningful moment was microanalytically coded via a developed coding system, and behaviourally described. RESULTS: The coding system reliably coded behaviour at the micro level. Exploratory results indicated that looking, movement and touching were most shown, and that staff displayed this behaviour more frequently than their clients. Both exhibited behaviours substantially more often during meaningful moments than at their onset. DISCUSSION: People with profound intellectual disabilities are more engaged during meaningful moments of interaction compared to at their onset. In daily practice, cultivating circumstances increasing their involvement is important.

This study aimed to examine the level of discrimination against people with intellectual disability during COVID-19, and assessed stereotypes, levels of familiarity with people with intellectual disability, and personal experiences with COVID-19 as potential correlates. A cross-sectional study was conducted using a large sample from the Dutch population (n = 1,797). Salient stereotype factors of people with intellectual disability were "friendly" and "in need of help," but not "give nuisance." Those respondents who were unfamiliar with people with intellectual disability in real life demonstrated higher levels of discrimination, perceiving them as more of a nuisance and as being less in need of help, in comparison to those who were more familiar. People with intellectual disability were judged by an ambivalent set of stereotypes during the COVID-19 pandemic that were in line with pre-COVID-19 findings and as such seemed to be fairly persistent and robust. There is a pressing need to both raise awareness of stereotypes towards and discrimination against people with intellectual disability via advocacy and education, and to facilitate positive encounters.

This study examined the general public's perceptions of how the COVID-19 pandemic has impacted the elderly and people with intellectual disabilities as well how these perceptions relate to people's level of familiarity and contact quality with these groups. A cross-sectional survey was administered to a sample of the Dutch population (n = 1458 and n = 1761, comprising questions related to the elderly and people with intellectual disabilities, respectively). The general public was found to be generally aware of the deleterious impact of the pandemic upon the elderly and people with intellectual disabilities. Specifically, the respondents reported that both groups' quality of life, physical and mental health, and quality and frequency of social contact was lower than it was prior to COVID-19, in addition to perceiving them as lonelier and less self-reliant. Notably, the impact on the elderly was considered to be greater than that on people with intellectual disabilities. Furthermore, those who had no familiarity with people with intellectual disabilities in real life perceived the impact to be lower than those who had a greater degree of familiarity. These findings have important implications, both for increasing awareness of the pandemic's negative impact on these vulnerable groups and in terms of sufficiently addressing their specific needs and concerns. The findings also underscore that, particularly during the COVID-19 pandemic, it is important to increase the visibility of groups who already relied more on help and support from others in society prior to the pandemic, such as the elderly and people with intellectual disabilities, via, among other things, self-advocacy, education, and enhanced intergroup contact, in order to be able to sufficiently address their needs during these challenging times.

Families play an important role in the lives of people with intellectual disability as they do for everyone. However, little research has addressed the views of people with intellectual disability about their families by using self-report. Individual family members may hold different views about their family relationships. Therefore, we used a social capital theoretical perspective to examine (a) how perceptions of people with mild intellectual disability (MID) about their family support networks compare to those of their family members and (b) what factors are associated with any diverging perceptions. Randomly selected participants with MID (n = 111) and their family members (n = 111) were interviewed individually at their homes using the Family Network Method-Intellectual Disability (FNM-ID). The FNM-ID examines how people define their family groups and how they perceive existing supportive relationships within this group. The findings showed that participants with MID perceived that they had somewhat denser family networks (i.e., bonding social capital) than family members perceived them to have and were more likely to report bridging social capital. They reported more relationships that involved them providing support to family members. This difference in estimation was greater when the participant with MID displayed higher levels of externalizing behaviour problems. They also perceived more reciprocity in their relationships with family. No differences were found in the estimated numbers of significant family members and relationships in which support was received. It is concluded that people with MID and their family members have different perceptions on several aspects of the family support network. Family professionals and services should seek the views of people with intellectual disability and their family members when carrying out assessments or organizing supports.

Hydrolysis is considered to be the rate-limiting step in anaerobic digestion of waste activated sludge (WAS). In this study, an innovative 4 stages cascade anaerobic digestion system was researched to (1) comprehensively clarify whether cascading configuration enhances WAS hydrolysis, and to (2) better understand the governing hydrolysis kinetics in this system. The cascade system consisted of three 2.2 L ultra-short solids retention times (SRT) continuous stirred tank reactors (CSTRs) and one 15.4 L CSTR. The cascade system was compared with a reference conventional CSTR digester (22 L) in terms of process performance, hydrolytic enzyme activities and microbial community dynamics under mesophilic conditions (35 °C). The results showed that the cascade system achieved a high and stable total chemical oxygen demand (tCOD) reduction efficiency of 40-42%, even at 12 days total SRT that corresponded to only 1.2 days SRT each in the first three reactors of the cascade. The reference-CSTR converted only 31% tCOD into biogas and suffered process deterioration at the applied low SRTs. Calculated specific hydrolysis rates in the first reactors of the cascade system were significantly higher compared to the reference-CSTR, especially at the lowest applied SRTs. The activities of several hydrolytic enzymes produced in the different stages revealed that protease, cellulase, amino peptidases, and most of the tested glycosyl-hydrolases had significantly higher activities in the first three small digesters of the cascade system, compared to the reference-CSTR. This increase in hydrolytic enzyme production by far exceeded the increase in specific hydrolysis rate, indicating that hydrolysis was limited by solids-surface availability for enzymatic attack. Correspondingly, high relative abundances of hydrolytic-fermentative bacteria and hydrogenotrophic methanogens as well as the presence of syntrophic bacteria were found in the first three digesters of the cascade system. However, in the fourth reactor, acetoclastic methanogens dominated, similarly as in the reference-CSTR. Overall, the results concluded that using multiple CSTRs that are operated at low SRTs in a cascade mode of operation significantly improved the enzymatic hydrolysis rate and extend in anaerobic WAS digestion. Moreover, the governing hydrolysis kinetics in the cascading reactors were far more complex than the generally assumed simplified first-order kinetics.

BACKGROUND: Based on self-reported social capital, different typologies of family networks of people with intellectual disabilities were examined. Associations between behavioural and emotional problems or well-being and typologies were investigated. METHOD: 137 participants with mild intellectual disability were interviewed using the Family Network Method-Intellectual Disability to assess their emotionally supportive family relationships. Data on participants' well-being and behavioural and emotional problems were also gathered. Latent class analysis was used to identify family typologies based on social network measures. RESULTS: Four distinguishable typologies were identified, two supportive and two less supportive. A small association was found with behavioural and emotional problems and one of the supportive typologies. Associations with constructs of well-being were found for both supportive and less supportive typologies. CONCLUSIONS: A variety of family types were found, with implications for sensitive professional support.

Even though family plays a significant role in the lives of people with intellectual disability, little research has included their own views about their families. This study examined how 138 people with mild intellectual disability describe their family group, with a focus on the reciprocal nature of the emotional support in relationships with family members. Participants reported "significant" family members beyond the nuclear family, and parents were seen as the main provider of support. Only half of participants had a support relationship with siblings and just 13% of participants reported partners. About 30% of support was reciprocal, and reciprocity varied greatly with the types of family connection (e.g., siblings, peers). Implications for future research as well as practice are discussed.

The thermal hydrolysis process (THP) is a sludge treatment technique which affects anaerobic biodegradability, viscosity and dewaterability of waste activated sludge (WAS). In 2011 a THP-pilot plant was operated, connected to laboratory-scale digesters, at the water board Regge en Dinkel and in cooperation with Cambi A.S. and MWH Global. Thermal hydrolysis of WAS resulted in a 62% greater volatile solids (VS) reduction compared to non-hydrolysed sludge. Furthermore, the pilot digesters could be operated at a 2.3 times higher solids loading rate compared to conventional sludge digesters. By application of thermal sludge hydrolysis, the overall efficiency of the sludge treatment process can be improved.
