- We report a patient with advanced Parkinson's disease, including severe and frequent off periods with freezing of gait, moderate dysphonia, and some cognitive impairment, who underwent bilateral subthalamic nucleus (STN) stimulation. The patient was followed for 1 year after surgery, showing persistent good mobility without off periods and without freezing, which reverted completely when stopping the stimulation. There was deterioration of cognition as well as increased aphonia and drooling, all of which remained when the stimulation was turned off. The striking improvement in motor symptoms following STN stimulation was not paralleled by improvement in disability, probably as a result of a cognitive decline, suggesting a diagnosis of Parkinson's disease with dementia. We conclude that chronic STN stimulation is efficient in alleviating akinetic motor symptoms including gait freezing; this surgery should be offered before patients start to exhibit speech or cognitive disturbances.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- ABSTRACTMany studies have been conducted on infanticide and child homicide. Researchers have approached the subject with different theoretical frameworks and explored it from different dimensions, geographical areas, and time periods. As much as the questions have varied so have the answers. This study contributes to greater clarity on the causes of infanticide. Despite numerous studies on the subject, there is still no consensus its causes. My aim has been to combine different strategies for understanding the subject. I have used material both from an aggregated level and from an individual level. The main question I sought to answer was whether social causes rather than individual factors force or trigger women to kill their newborn child? Court material also provides for an in-depth understanding of our history. The social sciences have frequently drawn sketches of the social world with big lines. These lines have been necessary and useful to point at large-scale transformations of civilisation and modernisation but, in terms of understanding real life, they can provide us with a foggy and even mistaken picture. When social scientists enter the historical archives and similar sources, we often blunder in its richness and variation. Society may, in any case, have always been complicated and the every day life for each person as well.My findings show that infanticide signals low tolerance. In general, the women did not want to kill their own children. Moreover, my findings, like the results of other studies before mine, demonstrate that women who carry out infanticide represent normal women. To my knowledge, there isn’t one study on infanticide that claims the women were not normal. Women who committed infanticide did so out of fear: fear of losing their social bonds. They killed their children if the existence of the bonds was endangered or threatened. Often social bonds were related to their work situation as maids in farming households. If they couldn’t stay in the household after having the baby, many women had no where else to go. Their parents – poor, elderly or deceased – were unable to help. Sometimes the social bonds were threatened by other factors, often related to the child’s father. If he was already married or had a close relation with the woman’s family, their relationship could in fact, break her bonds to her own family and other relatives. Some women already had an illegitimate child. With a child out of wedlock, they had a difficult time getting work and housing. If they got pregnant again and the father to the new child refused to marry her or to support the child, she could in fact lack any resources for handling the situation.Finally: the findings talk about honour and infanticide. It was always shameful to get a child out of wedlock. But demographic research from North of Sweden has shown that these children had almost the same chances of survival during their first year as legitimate children. Sexuality outside marriage was not respected but much discussion around honour was more related to how the women would manage with the child. In my findings, shame seems to be related to having no support. Extramarital relations were not accepted but people probably didn’t care to much about it as far as they managed on their own. Being rejected, helpless, not able to work and not able to take care of the child that was what shame was about.Keywords: Infanticide, child homicide, illegitimacy, social bonds, shame

Predictive control over wireless multi-hop networks

- Remote control over wireless multi-hop networks is considered. Time-varying delays for the transmission of sensor and control data over the wireless network are caused by a randomized multi-hop routing protocol. The characterstics of the routing protocol together with lower-layer network mechanisms give rise to a delay process with high variance and stepwise changing mean. A new predictive control scheme with a delay estimator is proposed in the paper. The estimator is based on a Kalman filter with a change detection algorithm. It is able to track the delay mean changes but efficiently attenuate the high frequency jitter The control scheme is analyzed and its implementation detailed. Network data from an experimental setup are used to illustrate the efficiency of the approach.

- Designing quality of service (QoS) guaranteed communication protocol for wireless sensor networks (WSNs) is essential to exploit the advantages and flexibilities offered by this technology for real-time control and actuation applications. A novel cross-layer protocol that embraces altogether a semirandom routing, MAC, data aggregation, and radio power control for clustered WSNs is presented. The protocol leverages the combination of a randomized and a deterministic approach to ensure robustness over unreliable channels and packet losses. An optimization problem, whose objective function is the network energy consumption, and the constraints are reliability and latency of the packets is modelled and solved to adaptively select the protocol parameters by a simple algorithm. As a relevant contribution, the proposed protocol is completely implemented on a test-bed, and it is compared to existing protocols. Experimental results validate the analysis and show excellent performance in terms of reliability, latency, low node duty cycle, load balancing and dynamic adaptation to the application requirements.

Medium Access Control Analytical Modeling and Optimization in Unslotted IEEE 802.15.4 Wireless Sensor Networks

Konferensbidrag (refereegranskat)abstract
- Accurate analytical expressions of delay and packet reception probabilities, and energy consumption of duty-cycled wireless sensor networks with random medium access control (MAC) are instrumental for the efficient design and optimization of these resource-constrained networks. Given a clustered network topology with unslotted IEEE 802.15.4 and preamble sampling MAC, a novel approach to the modeling of the delay, reliability, and energy consumption is proposed. The challenging part in such a modeling is the random MAC and sleep policy of the receivers, which prevents to establish the exact time of data packet transmission. The analysis gives expressions as function of sleep time, listening time, traffic rate and MAC parameters. The analytical results are then used to optimize the duty cycle of the nodes and MAC protocol parameters. The approach provides a significant reduction of the energy consumption compared to existing solutions in the literature. Monte Carlo simulations by ns2 assess the validity of the analysis.

Nordic Children's Foodscapes: Images and Reflections
- 2009

Ingår i: Food, Culture and Society: An International Journal of Multidisciplinary Research. ; 12:1
-
Tidskriftsartikel (refereegranskat)abstract
- A study of the different food messages that children encounter and their own reflections of these messages was carried out among fifty-nine children from Denmark, Finland, Norway and Sweden. The children took photos of their "foodscapes," including school, home, shops, streets, cafés and restaurants. The themes were healthy and unhealthy food, everyday and festive food and their favorite food. The children were well aware of common understandings of healthy/unhealthy food. They labeled fruit, vegetables and fiber-rich foods as healthy and foods rich in sugar, fat and salt as unhealthy. Unhealthy eatables belonged to festive contexts, such as cozy evenings and birthday parties. The everyday food in school and at home was considered healthier, often consisting of well-composed meals including vegetables. The children's favorite foods belonged to both the healthy and unhealthy categories. The children also dealt with the contradictions between everyday healthy food and unhealthy festive food, which involved adjusting to different social and spatial contexts.
