Community violence in Dar es Salaam, Tanzania: A mixed methods study

Most homicide deaths in Dar es Salaam, Tanzania (DSM) are a result of violence arising from within the community. This type of violence is commonly called, by perpetrators and victims, “mob justice”. Unilateral non-state collective violence can take four forms: lynching, vigilantism, rioting, and terrorism. The purpose of this paper is to report what leads to death by such violence in DSM. A cross-sectional mixed methods study design was used. Surveillance data were collected on all 206 victims of “mob justice” in DSM for the year 2005. Fifteen in-depth interviews were conducted with the relatives of deceased victims, a policeman, a journalist, community members, and youths who survived these types of community violence. A focus group discussion was conducted with eight youths at risk of such violence. The deceased were young adult males and differed significantly from assault victims as to age, occupation, weapon causing death, and injury site. Ninety percent were identified as: unemployed, thieves, unknowns, or street vendors. The immediate history of the deceased usually involved theft. The stated desire of community members was to live in peace; they acknowledged that murder is unlawful. Often the victims had been warned; if transgressions continued, male community members punished the individual, which led to death. Family reactions varied from relief, to confusion, and loss. Community level violence in DSM is defensive; the goal is to protect the community. It is focused on individuals, not groups; incidents can be classified along the continuum of lynching and vigilantism in which lynching is a spontaneous reaction to deviance and vigilantism is an organised activity. Decreasing the number of deviant social acts should theoretically decrease cases of lynching and vigilantism. The most humane way to decrease petty theft is through appropriate employment.Keywords: homicide; Africa; Tanzania; vigilantism; lynching; community; mo

Until death do they part: preventing intimate partner homicide\ud

Just under one quarter of all homicide victims in England and Wales were killed by an intimate partner in the year 2008/9, according to Home Office statistics. In the aftermath of such fatalities, where the offender was clearly well known to the victim, questions are often raised about whether the attack could have been foreseen and whether services had failed the victim in not preventing the sometimes seemingly inevitable event. This article considers how psychological theory and research can lend itself to the prevention of serious and fatal intimate partner violence and looks at the current state of practice in this domain

The heterogeneity of family violence and its implications for practice

Reviews on the causes of aggression in the family have emphasised the extensive overlap between all forms of partner violence and child maltreatment. However, research into family violence has often investigated child and partner maltreatment as separate entities, frequently\ud examining the violent man in order to understand the correlates and potential causes of his violent behaviour within the family. This review highlights the importance of examining intimate partner violence within the context of the family. First the violent man is considered in\ud isolation, exploring the heterogeneity of men who abuse and murder their female partner and the implications this has for future practice and research. Second, taking into account the overlap of partner and child maltreatment and the reciprocal nature of intimate partner violence, the utility of examining family violence from a more family focused perspective is considered. It is concluded that an integrated perspective will increase interagency collaboration and integrative treatment for the family

Lack of Mutual Respect in Relationship The Endangered Partner

Violence in a relationship and in a family setting has been an issue of concern to various interest groups and professional organizations. Of particular interest in this article is violence against women in a relationship. While there is an abundance of knowledge on violence against women in general, intimate or partner femicide seems to have received less attention. Unfortunately, the incidence of violence against women, and intimate femicide in particular, has been an issue of concern in the African setting. This article examines the trends of intimate femicide in an African setting in general, and in Botswana in particular. The increase in intimate femicide is an issue of concern, which calls for collective effort to address. This article also examines trends offemicide in Botswana, and the antecedents and the precipitating factors. Some studies have implicated societal and cultural dynamics as playing significant roles in intimate femicide in the African setting. It is believed that the patriarchal nature of most African settings and the ideology of male supremacy have relegated women to a subordinate role. Consequently, respect for women in any relationship with men is lopsided in favor of men and has led to abuse of women, including intimate femicide. Other militating factors in intimate femicide ,are examined and the implications for counseling to assist the endangered female partner are discussed

Analysis of the high-speed polysilicon photodetector in fully standard CMOS technology

A high-performance lateral polysilicon photodiode was designed in standard 0.18 um CMOS technology. The device has a frequency bandwidth far in the GHz range: the measured bandwidth of the poly photodiode was 6 GHz, which gure was limited by the measurement equipment. The high intrinsic (physical) bandwidth is due to a short excess carrier lifetime. The external (electrical) bandwidth is also high because of a very small parasitic capacitance (<0.1 pF). This is the best bandwidth performance among all reported diodes designed in a standard CMOS. The quantum efficiency of this poly photodiode is 0.2% due to the very small light sensitive diode volume. The diode active area is limited by a narrow depletion region and its depth by the technology

High-resolution optical frequency dissemination on a telecommunication network with data traffic

We transferred the frequency of an ultra-stable laser over a 108 km urban fiber link comprising 22 km of optical communications network fiber simultaneously carrying Internet data traffic. The metrological signal and the digital data signal are transferred on two different frequency channels in a dense wavelength division multiplexing scheme. The metrological signal is inserted into and extracted from the communications network by using bidirectional off-the-shelf optical add-drop multiplexers. The link-induced phase noise is measured and cancelled with round-trip technique using an all-fiber-based interferometer. The compensated link shows an Allan deviation of a few 10-16 at one second and below 10-19 at 10,000 seconds. This opens the way to a wide dissemination of ultra stable optical clock signals between distant laboratories via the Internet network

Intimate partner violence and stalking\ud

“Stalker guilty of stabbing ex-girlfriend to death in "brutal' attack”, reads the London Evening Standard news headline (Bailey, 2010). This article goes onto describe how Gemma Doorman, 24, was stabbed to death in July 2008, as she left a restaurant in South-West London, by her ex-partner Vikramgit Singh. The ‘frenzied attack’ occurred after months of stalking and harassment, which Miss Doorman had previously reported to the police. This is just one example of many worldwide media headlines that depict stories of relationships that have culminated in the murder of one partner. While, not all cases of partner homicide are characterised by stalking and harassment, most victims of stalking know their perpetrator, and in a large proportion of stalking cases the target is an ex-intimate partner (Spitzberg, 2002). Such murder cases provoke questions about why the fatality occurred and whether this arguably foreseeable event could have been prevented. These are questions that many academics and practitioners in the field have endeavoured to answer

Sb-based low-noise avalanche photodiodes

Accurate detection of weak optical signals is a key function for a wide range of applications. A key performance parameter is the receiver signal-to-noise ratio, which depends on the noise of the photodetector and the following electrical circuitry. The circuit noise is typically larger than the noise of photodetectors that do not have internal gain. As a result, a detector that provides signal gain can achieve higher sensitivity. This is accomplished by increasing the photodetector gain until the noise associated with the gain mechanism is comparable to that of the output electrical circuit. For avalanche photodiodes (APDs), the noise that arises from the gain mechanism, impact ionization, increases with gain and depends on the material from which the APD is fabricated. Si APDs have established the state-of-the-art for low-noise gain for the past five decades. Recently, APDs fabricated from two Sb-based III-V compound quaternary materials, AlxIn1-xAsySb1-y and AlxGa1-xAsySb1-y, have achieved noise characteristics comparable to those of Si APDs with the added benefit that they can operate in the short-wave infrared (SWIR) and extended SWIR spectral regions. This paper describes the materials and device characteristics of these APDs and their performance in different spectral regions
